The History Of Travel Agencies

The History Of Travel Agencies Travel agencies exist mainly as intermediaries among suppliers of travel services such as carriers and hotels, and customers. Travel agencies do not deal with tangible products but with information where it is different from other distributors in many industries (Cheung Lam, 2009). As for the travel agent it is best defined as an individual who undertakes a work for another individual, who is being the principal. The principal in such an affiliation not only sets the aims of the work, such as selling tickets, however can also control the means and way in which the work is completed (Cheung Lam, 2009). Cheung Lam (2009) added that modifications in the business over the past ten years have affectedly changed the environment and significance of info in the travel industry and, subsequently, the role of travel agency. Lately, the technology advancement has brought changes in tourism industry. Why did the Internet so affectedly affect the travel industry? What impact do the changes have on travelers? (Harrell Associates, 2002). The Internet has revolutionized the method in which customers make their travel choices (Anon, 2012). Customers nowadays have several additional selections because the Internet offers providers additional chances to generate direct customer relations and allows a varied range of pricing (Harrell Associates, 2002). The Internet offers an influential atmosphere for the conception of virtual representations of tourism destinations permitting indirect experience that really exceeds the potentials of traditional travel agents (Bogdanovych, Berger, Simoff Sierra, 2005). Currently the Internet is the perfect connection among customers and dealers, over hundreds of websites, travelers have sufficient information for their travel preparation (Ortega, 2008). According to Travel Indus try Association of America (TIA) over 75 million online travelers used the Internet for their travel planning such as to look for places to stay, rental car prices, also searching for maps and driving directions, searching for airfares and schedules and other information about tourist destinations (Ortega, 2008). According to Ortega (2008), he said that the travel planning and booking on the Web are among the greatest popular online activities in best important e-commerce markets and online travel sales are rising at an explosive amount (over $115 billion this year) in the US, Europe and the Asia-Pacific regions. Therefore, because of the growing of the e-commerce in the tourism industry, the tourists have numerous selections provided by the Internet to obtain online, in the ease of their houses or offices, touristic services and products (Ortega, 2008). Furthermore, the Internet assists to locate low prices in tourist services such as air tickets and hotel rooms. In conclusion, it offers tourists a remarkable total of information to make an exclusive trip. According to Vrana (2010), she claimed that a main forte to travel agencies is the capability to offer personal information and assistance to tourists endlessly, along with consultancy service for corporations and will keep on secure if their advice-offering ability remained supported by the existence of the Internet. Even though there are many online travel services, a traditional travel agent is as far a vital part of the trip as ease is to traveling! (Will, 2012). The travel industry is comprised of over a dozen related industries: airlines, restaurants, hotels/motels, travel agencies, gift shops, auto rentals, and a host of other businesses that may not be even recognized their dependence on travel and tourism since travelers are usually indistinguishable from local customers (Cheung Lam, 2009). Will (2012) also stated that, the part of a travel agent has remained growing with the eras and currently most people are reliant on them for fulfilling most of their travel plans so tha t they can rest calmly and just relish their trip. This study aims to examine the factors involves in sustaining travel agencys operation in order to survive in this tourism industry and evaluate their performance or sales of travel agency that can affected by the uses of technology such as Internet. 1.1 RESEARCH ISSUES Tourism has become the second largest economy contributor after manufacturing. One of the factors that contributes to the boom of tourism market is the advancement of technology. Travel industry are comprises of variety related industries, such as airlines, travel agencies, restaurants, hotel/motel and more (Cheung Lam, 2009). More or less, each of the related industry will get at least a little impact from the technology advancement, notably these travel agencies. There is some research that indicates that tourism product is popular to be bought through online (Nysveen Lexhagen, 2001). Online tourism has grown rapidly as the consumer nowadays are using the advancement of technology to acquire information and also purchasing tourism products and services (Dixit, Belwal Singh, n.d). There are many reasons why consumer tends to choose Internet as one their medium in purchasing tourism product and services. One of it is Internet are giving them cost-saving convenience (Cheung Lam, 2009). Cost-saving convenience means that there are no efforts required for the consumer to spend their time and money to seek for information needed about a certain package. Some of the consumers also choosing Internet rather than looking for travel agencies because of the flexibility that Internet has to offer. The consumer are seeking flexible tourism product to suit their travel needs (Harris Duckworth, 2005). Based on their research, the consumers buying pattern recently has change rapidly to independent travel from the typical package holiday. To support this statement, they are adapting a research done by Mintel, in UK independent travel has conquered the travel market in 2004 with 55%. The other reason why consumers tend to choose Internet over travel agencies is because of online experience has greater potential in visualizing travel destinations (Bogdanovych, Berger, Simoff Sierra, n.d). They also stated that online technology offers 3D interactive tours that can deliver clearer image on the destination. Interactive videos can also be shown online without interrupting other customers. Based on a study done by Daugherty, Hairong Biocca (2005) which they wanted to get consumers reaction on the product presentation method. The two choices are indirect experience (virtual presentation), and direct experience (direct product manipulation). The results proved that, product knowledge and decision quality made by the consumer are both significantly higher when they are exposed to interactive 3D products than to static products presented in a form-based way. Despite from all the factors, travel agencies which are at stake need to survive in order to sustain their spot in the travel industry. They have to differentiate themselves more than what technology advancement has to offer. Based on the statement of research problem, we want to conduct a research on how travel agencies can sustain their operation. There are a few factors that make travel agencies can sustain themselves in tourism industry in Malaysia. These factors can determine the sales of the travel agencies because the trade travel agency community has sustained substantial losses due to the mutual effect of the growth of Internet (Cole, 2009) 1.2 STATEMENT OF RESEARCH PROBLEM Generally, in real world, an increasing competition from other channel had caused the number of traditional travel agents nearly decrease (Buhalis, 2003). The Internet is changing the industrys structure and the consumers behavior. Widely used of technology in tourism industry has affect the operation of the travel agencies in Malaysia. The usage of Internet by travelers has decreased the number of travel agencies sales in Malaysia. Besides that, Internet also has caused the high street travel agencies to close, thus creating job losses within the businesses (Anon, 2010). Many studies have looked into The Internet Travel Industry: What Consumers Should Expect and Need to Know, and Options for a Better Marketplace (Harrell Associates, 2002), Travel Agents vs. Online Booking: Tackling the Shortcomings of Nowadays Online Tourism Portals (Bogdanovych, Berger, Simoff Carles Sierra, n.d), Evaluating the Adoption and Use of Internet-based Marketing Information Systems to Improve Marketing Intelligence : The Case of Tourism SMEs in Jordan, AL-allak, 2010), Attitudes Towards Internet Use Among Travel Agencies In Greece (Vasiliki, Costas Savvas) and Travel Agents Fight A Losing Battle With the Internet (World Airline News, 2008). Unfortunately, there is no specific study that evaluates or observes on the factors that lead to the methods of sustaining the travel agencies operation in Malaysia regarding on the technology advancement. 1.3 RESEARCH OBJECTIVES 1) To identify the factors that capable to sustain the operation of travel agencies in Malaysia 2) To identify whether the performance or sales of travel agency are affected by the uses of technology such as Internet or not. 1.4 RESEARCH QUESTION 1) What are the factors that can sustain the operation of travel agencies in Malaysia? 2) Does the performance or sales of travel agency are affected by the uses of technology such as Internet? 1.5 CONCEPTUAL FRAMEWORK Independent variables Dependent variable Sustainability factors: à ¢Ã¢â€š ¬Ã‚ ¢ Human Touch à ¢Ã¢â€š ¬Ã‚ ¢ Negotiation Power à ¢Ã¢â€š ¬Ã‚ ¢ Interpersonal Skills à ¢Ã¢â€š ¬Ã‚ ¢ Niche Market Travel agencys operation Figure 1: Proposed framework for the study 1.6 SCOPE OF THE STUDY The scope of the study is using the travel agencies around the Klang Valley area. All the travel agencies that took part in this study offers wide-range of services and products in their company. These travel agencies have been selected according to their location that located in Kuala Lumpur and Selangor. Most of the travel agencies are located in Kuala Lumpur. 1.7 SIGNIFANCE OF THE STUDY This study will basically benefit few categories of organizations that play important key roles in the tourism industry. Firstly, the government bodies such as the Ministry of Tourism, Tourism Malaysia and travel agencies in Malaysia. Secondly, this study will benefit the educational institution especially academicians and students in the tourism line. Therefore, it is hoped that this study can act as a guide and reference in future studies. There might be some filed in this study that is not investigate thoroughly due to constraint of time and funding and therefore it is welcome for any future researcher to examine those intended field. 1.8 LIMITATIONS OF THE STUDY For this study, we were using online survey. In order to deliver the questionnaires, we need to use an email. We took the email address of travel agencies from MATTA website, MOTOUR website and also their own website, however, some of the emails are not valid. This problem leads to the difficulty in collecting the information and giving us some difficulties in processing the result. Other than that, some of travel agencies did not give cooperation to us. They were not answering the questionnaires even though we already stated that all information are confidential and only use for study purposes. Lack of the cooperation and resources limit the researchers to gain extra information to enhance the study. 1.9 SUMMARY This chapter has presented the background of the research and research problem, outlining the research objectives and questions relevant to the research topic. This chapter also covered the scope of the study together with the importance in conducting the research. CHAPTER 2 LITERATURE REVIEW 2.0 INTRODUCTION This study aims to discover the factors that can make the travel agencies in Malaysia sustain its operation in this tourism industry. In order to achieve the objectives of the study, literatures regarding the sustainability factors will be examine. 2.1 HUMAN TOUCH According to a professor of psychology, Dacher Keltner from a University of California, Berkeley, he says that, touch is our richest means of emotional expression. The researcher found out that, touch interconnects in ways that words cannot (Moll, 2012). In retail store settings, concisely touching customers has been shown to rise the consumers shopping times, store valuations and purchase volumes (Lynn, Le, Sherwyn, 1998). According to Jochman (2009) in his article title The Benefit of Human Touch, he said that the quantity of body contact plays an important role in peoples physical growth and mental as infants and in our happiness as an adults as shown by the scientists. Human touch has experience of working with banks, credit unions, insurers and other financial service providers to increase awareness of how service excellence can have a dramatic impact on their bottom line (Anon, 2012). A service representative asking the right questions and being sensitive to a customers needs can make all the difference between the sale of a financial product and the loss of that business to a competitor (Anon, 2012). In the years of computer-generated workplaces, where e-mail, teleconferencing and fax machines increase, something is missing that American business people need to close a deal the human touch (Seaberry, 2000). In other words, handshake and looking at each others eyes are still needed by the business people. According to James J. Green (2012) in his article, he said that the personal touch-the person-to-person touch-that you offer to your clients the one that distinguishes you. He added that talking to your peers, in person, provides you with perceptions that you cannot get electronically. Individuals play an important role in any business relationship because it is actually managed by individuals (Nguyen Nguyen, 2011). In manufacturer-distributor relationships, personal interactions talk about the communication at the individual level between distributors and manufacturers vital contact people (Ulaga, 2003). Furthermore, research has shown that personal interaction can play a critical role in distributors valuations of suppliers performance (Ulaga, 2003). As said by Kaufman (2012), automation is vital for growing and speeds up service in many industries. However, he added that when individual care or courtesy is required, customers require contact with real people. Once human energy fl ows and connects, good things can get completed and you can increase customer experience to your advantage (Kaufman, 2012). Scholars in marketing and organizational behavior are present giving increasing attention to the personal interaction among the customer and the employee on the frontline of service businesses (Mattsson, 1994). The personal interaction is recognized to be one of the important subjects in business and industrial marketing, both in terms of practice and theory (Mainela Ulkuniemi, 2012). Mainela and Ulkuniemi (2012) also stated in their journal that, personal interaction is also required to exchange social values and it may weaken the involvement of price in determining the behavior of the two parties. According to Pinnington and Scanlon (2009), business relationships are actually managed by individuals and there is extensive personal interaction in any business relationship (Pinnington Scanlon, 2009). Research has shown that a lot of companies are moving from transactional separate relations to relational ones (Nguyen Nguyen, 2011). In addition, Tho D. Nguyen, Trang T.M. Nguyen (201 1) said that, committed relationships are among the most durable because they are difficult for competitors to comprehend, to duplicate, or to relocate. Thus, scholars and practitioners have agreed that two-way relationships between buyers and sellers represent a source of competitive advantage (Nguyen Nguyen, 2011). Travel agent might look similar to a profession of the past, just like elevator operators and milkmen, however they are not merely hanging on, certain of them are successful. In actual fact, the February/March topic of Shop Smart magazine has a story on travel agents, saying that they are a lot better than online travel services (Williams, 2008). In the article title Travel agents: Hong Kongers prefer the real thing, Hong Kong travelers blame the online trend and continue to choose for humans when booking vacations (Li, 2012). Li (2012) also said that, Hong Kong is not a huge city; it is appropriate for people to make straight contact with travel agents as they are the expertise and backing that an offline travel adviser can convey additional value to the holiday. Travel agents will make sure that you will have an incredible experience on your trip. They are excited and will show their enthusiasm in helping you, their clients, have the best vacation possible (Bow, 2012). Travel profe ssionals are individually invested in seeing your trip come to be a success trip. This personal interaction with existent, live agents undermines the frequent dull experience of doing it yourself online (Bow, 2012). As soon as you book a trip or a holiday with a travel agent, you create a personal as well as a business rapport with that travel agent. If something goes incorrect, your travel agent is your personal representative who has an entrusted concern in resolving the problem to your satisfaction (Morris, 2012). According to Geoff Williams (2008), if you are afraid that you will need to change your flight or your travel plans at the last minute, a travel agent might be capable to talk to an airline directly and will save you away from those worries and stresses. Even though growing numbers of people turning to technology, specialists on both sides of the bureau are saying that there will always be a space for the human touch (The Syedney Morning Herald, 2007). Wherever travel agents remain incomparable is in their capability to offer a personal service. Naisbitt (2001) refers to it as high-touch, the antidote to high-tech. Moreover, it is becoming increasingly evident that agencies will need a high-touch high-tech strategy to satisfy the customers of the future (Naisbitt, 2001). A website cannot provide what the travel agent can offer such offering help, advice and also that personal touch to your travel planning experiences (McNally, 2007). According to the technology advisor Mary O Haver, the experience that travel agent has is part of the personal touch that travel agents can offer. Besides that, according to Hoffman (2012) who is an online travel expert and managing director of the worlds largest online travel agency, expedia.com.au, peo ple will always like to walk into a store and get personal service. He also said that, the more complex the trip, the more cooperative an experienced agent will be. He continued that, an agent can guide an inexperienced traveler over foreign travel or travel to exotic destinations. When travel in less developed tourism destination, the travel agents may have more knowledge of travel about that destination (Morris, 2012). Complicated arrangements like various destinations on one ticket or group travel might turn into difficult and an agent with experience can help (Morris, 2012). According to Olmsted (2012) in his article, between the several main advantages of high-powered agents carry to the table is individual connections and influence. If you have problems while you remain away, your travel agent is there to help you in resolving your concerns. If you make a booking with a travel agency, you are less likely to experience flight, city, or accommodation changes by the tour company, as they know the agent will be there to stand behind you (Travel Cafà © Inc, 2012). If you have at present reserved your trip but before you go to travel you want to adjust some details, your travel agency can assist you by get all the required steps complete, leaving you without the difficulty and confusion (McNally, 2007). Travel agencies take care of all travel particulars form reserving tickets to booking hotels that can give the tourist sufficient time to plan the travel (McNally, 2007). According to Donvan Lieberman (2011), the human touch that makes travel agencies different is when something goes wrong with our trip; we have someone to call or refer to solve the problem. Compared to persons who booked their accommodation or flight tickets online, there was no one for them to refer to help them resolve that situation. Secondly, according to them, travel agents are giving services by giving real information or their personal experience on the destination spots they send people to. They can also give travel tips that maybe useful where we cannot get them from online information. If a person booked online, if there is any mistakes happen during their bookings, they will have to carry the burden for themselves. But, using by the travel agents, they will do anything in order to personalize the needs and wants of their customer (Travel Cafà © Inc, 2011). Besides that, the travel agents are giving their specialized expertise that an individual does not have, or might fo rget during a trip. For example, visas, insurance, currency exchange and also custom regulation of a destination (Cole, 2009). Travel agents can help you to arrange and organize any compulsory official papers that you possibly will need in order to travel outside of the country (McNally, 2007). Rand McNally (2007) added that, travel agents know the necessary documents that you may need for your traveling such as visa and they can direct you to your local passport office too. Furthermore, travel agent can give extra services that an individual cannot get from online booking. One of the example is they have the ability to source and different travel experience and help to book hard booked restaurant (Talwar, 2011). Other than that, when you call with any problems during your trip, an online travel agency is not going to pick-up the phone but then a travel agent will remains to give you that personal care even though you are away (McNally, 2007). Building that personal relationship pro vides you the assurance that you can reliance on your agents expertise and no matter the situation, they will be around to assist you to find a resolution (Bow, 2012). Additionally, if you should have any enquiries after booking your trip, you know exactly how to contact your travel agent and can escape the uncertain FAQ section on a website (McNally, 2007). The services that serve with the human touch and worth deal will make the travel agency retain in the business. According to Geoff Williams in his article, he said that as soon as the tourism space getting bigger, you are going to have a choice in the middle of a thinking, helpful individual and a capable unfeeling internet site that does not surely care if you travel on Saturn whereas your baggage bursts into flames on Mercury. As for that, who are you going to trust? Smart Money magazine summarized the whole thing moderately well on the cover of the June 2007 edition. FORGET ONLINE! TRAVEL AGENTS GET BETTER DEALS. 2.2 NEGOTIATION POWER In general, negotiation mean bargaining process between two or more parties seeking to discover a common ground and reach an agreement to settle a matter of mutual concern or resolve a conflict (Business Dictionary.com). According to Fisher Ury in their book Getting to YES: Negotiating Agreement without Giving In, negotiating is a basic way in getting what you want from other people (1981). While in Oxford Dictionary, negotiation means discussion is aimed at reaching an agreement. In Women Are Getting Even (WAGE) website, they interpret negotiation as conversation between two parties in order to make an exchange. According to Rusk (2006), the meaning of negotiation is discussion intended to produce an agreement. It also can be referring as common solutions that used to make a decisions and settle down the problems (Moore, 2012), a process which is two or more parties attempt to agree on the rate of goods and services that they exchange (Robbins Judge, 2003). Conflict and negotiatio n are a fact of everyday work-life, yet it often produces anxiety (Cutts, 2012). The UK Border Agency has announced that there are still technical problems with online booking service (Kelly, 2012). This statement shows that sometimes online booking faced a problem such as lost record (Kirschbaum, 2009), security issues (Fane, 2010) and technical issues (Scoot, 2012). There are problems that faced by customer when they used online booking system. Despite the fact that all the respondents (except for one) use computers almost every day, 14% believe that booking online is not securing in general (Bogdanovych et al, 2006). Conflict happen because of these problems. Conflict happen when people did not agree with the issue, it will create a friction or tension between that individual or groups (Nahavandi, 1999). Negotiation is a process that examining the facts of situation, exposing the interest of both parties involved and bargaining to solve the conflict as many as possible (Moore, 2012). Negotiation permeates the interaction of almost everybody in the organization (Robbins Judge, 2003). According to Lucas (2008), conflict might occur because of differing perception, inadequate or poor communication and also contrary expectations. These problems often happen when dealing with customer especially in travel agency. In tourism industry, negotiation is an important process to gain a mutual agreement of something, especially for the travel agencies. It is crucial for them to confirm what their customer wants and need. Through negotiation conflict between travel agency and customer can be reduced. Negotiating through areas of conflict can often lead to win-win situations agreeable to parties, reducing ill felling and conflict (Queensland Government, 2011). Travel agents have the negotiation power because they have maximum choice to offer to their clients (Travel Cafà © Inc 2011). This means they have variety of choices that they can get from their travel suppliers and they can give us the best deal with best value of possible. Online booking lack of firsthand knowledge and rarely gives customer opportunity to speak with someone knowledgeable about service that they are booking (Morelock, 2012). The clients and travel agents can assists us to get what we need in our vacation and help us to get the best offer. Online booking allows customer to make all travel plans on the Internet means they can do it any time of the day or night at home or while theyre on their lunch break at the office (Oakley, 2012). It is true when we are doing booking online we can make a booking everywhere and anytime, where it will be more convenient to us, but we cannot negotiate the price of the tourism product that we wish to book. If we are negotiating with travel agents, we have the chance to get lower prices as possible. Price negotiation usually occurs during purchasing of materials or supplies (Francois, 2012). For example, if a travel package to Cameron Highlands costs about RM300 for two nights, the clients can negotiate to get the lower price and finally they will get the offer around RM250 only. With negotiations, both parties will receive their own benefits and it is a win-win situation (Rusk, 2006). When customer asks an agent to negotiate, means customer are essentially asking the agent to subsidize t heir vacation (Brock, 2009) but through online system, customer had no change to negotiate with an agent because the price is fixed. The Marriott International, Hilton Hotels, Sheraton Hotels Resorts and others was charged in San Francisco Federal Court on charges conspired to use their market dominance to fix the hotel prices with travel websites like Travelocity, Booking.com and Expedia, a subsidiary of Priceline.com From this case we can see that customer cannot negotiate the price because the price is fixed. The aim of the negotiations is to decide the price that is acceptable for both parties (Francois, 2012) From price negotiation process it becomes bargaining process. Negotiations commonly follow a process of positional bargaining (Cutts, 2012). Oxford Online Dictionary give two interpretation of bargaining, the first is an agreement between two or more people or groups as to what each will do for the other. The second is a thing bought or offered for sale much more cheaply than usual or expected. There are two types of negotiation which are distributive bargaining and integrative bargaining (Robbins Judge, 2003). Distributive bargaining also called claiming value, zero-sum or win-lose bargaining is a competitive strategy that is used to decide how to distribute a fixed resource such as money (Spangler, 2003). Honeyman (2012), interpret integrative bargaining as one of platform which party try to understand interests of another party, on the expectation that it will helping the opponent to create solution as responsive its own concerns. According to Tewart (2012), many times people say they dont like to negotiate (bargaining) yet, they still shop around and never pay full price. The word bargaining here does not only mean price negotiation, it is a much differentiated and broader term (Management Study Guide, 2012). Customer also can bargain to build his or her own trip with or without help from a customer care executive (Agarwal, 2012), asking whether travel agency offer travel insurance (trip Travel Responsibility Informed Protected, 2012) and a customer can seek redress under certain circumstances commonly referred as the right to repair, replacement or refund (Government of South Australia, 2011). These are things that customer can always bargain with travel agencies. The freedom for the customer is restricted when they make booking through online system. Customer cannot confirm their specific requirement when make the online booking through the hotel reservation system (Vyas, 2010). For example, when they make booking through hotel reservation system and they have something that they dont understand, there is no place for them to raise the questions. According to Lloyd, booking online doesnt have individual to deal with booking process, it leaf to customer to read and understand the complicated terms and conditions. One of the advantages of booking direct with the hotel, by phone or email, is that customer can request a specific room of the hotel and they cannot normally do that online or with an agent (Trend, 2010) According to Tewart (2012), most people act in their best interest and most people who say they dont like negotiating, actually still want to. This statement shows that customers still love to negotiate and online booking system prevent them from doing it. Negotiation is needed in order to secure the resources required for successful project completion (Evans Lindsay, 2008). Through negotiating win-win solutions with customers, it will not only give your company the best chance to succeed but will also create relation between customer and your company for future sales opportunities (Douglas, 2003). Negotiation also can increase clarity about the problem, can lead to innovative breakthroughs and new approaches, involvement in conflict can sharpen approaches to bargaining, influencing, competing and also can focus more attention on basic issues and lead to solution (Wertheim,1996). Solving problems that arise in negotiations is an integral part of collective bargaining. The first task is to recognize what is the problem that occurs and the secondly, is to decide what strategy should be taken to solve the problem (Anon, 2012). According to Goodale (2007), negotiation is one of the most important parts in business as well as one of the most interesting parts of professional purchasing

The Workplace As An Effective Learning Space Education Essay

The Workplace As An Effective Learning Space Education Essay Introduction Nowadays society, peoples understanding of learning space is no longer just confined to traditional areas of school education, but extends to all aspects of society. The workplace as an effective learning space, and its learning behavior has arouse widespread attention by educational theory and practice workers. Workplace learning as a form of learning, compared with traditional corporate training, not only improve employee skills to complete certain tasks, improve employee performance, change employee behavior and attitudes, but also to enhance overall quality of the employee, to enhance their knowledge to adapt to globalization and other external and internal environment change. Workplace learning is different from traditional forms of learning and training, it connected learner and worker, emphasizing to train the core competence, and get more and more attention. The rapid development of science and technology to accelerate the change cycle of the knowledge,also makes the work of those who need to use extensive knowledge or the main work is create knowledges employee face enormous pressure to update their knowledge and career development pressure. Especially the knowledge workers retraining and learning become the enterprise very concerned and attention problem. In the 1960s, the famous American scholars Foster once pointed out: the trainee get the employment opportunities in the labour market and the development prospects of taking office, is a key factor in the development of vocational education.Practical courses should be carried out within the enterprise, As far as possible reduction the distance between the regular school and the actual working situation.If you want to have some professional ability, it is necessary to participate in a solid and extensive vocational training; If you want to keep this professional ability and obtains the success in the future work, we must continue to develop own ability. Workplace learning is becoming an important form of lifelong learning. Many soft skills. Such as the ability to communication with others, methods ability, teamwork spirit, initiative and innovative spirit and so on.Its often acquisition in the work of informal learning rather than in formal education and training environment. Workplace learning challenge to the traditional education and the training system in some inherent formed. The concept of workplace learning Billet defines workplace learning as: à ¢Ã¢â€š ¬Ã‚ ¦is a way to participate in real task and members of skilled guidance of the activities directly or indirectly, acquire knowledge and skills in ways. (Billet 1993)  [1]   He put the knowledge of the study were divided into three types: 1. The declarative knowledge is the answer to what it is of the kind of questions. That the information on what things is. This kind of knowledge learning is the memory process. 2. The procedural knowledge is complete how do it of the kind of tasks. Must be demonstrated through practical activities. Such knowledge is the result of repeated practice and practice. 3. The tendentiousness knowledge is decided to do or not do, do what. For example. A person not willing to do something is hard to do it well. Do not even do it. Tendentiousness knowledge is the product of individual long-term emotional experience. In the workplace learning, procedural knowledge often can be directly observed, and conceptual knowledge of the content is rather ambiguous. Orientation determines the first two types of knowledge while knowledge creation, learning and use. Only three types of knowledge with each other in order to become full sense of the knowledge, have real value. According to the perspective of Mansfield, who defines workplace learning from the angle of skill, workplace learning is study method of learners developing working operational capacity in workplaces(Mansfield 1991)  [2]  .He points out that four forms of skills are required in work of learners: technical skill. task management skill. the capacity of planning. deciding,prioritizing and managing emergencies as well as role and environmental skills. He also stresses that the skill is integrated with important components of comprehension, emotion, value and emotional stability etc. A German professor Rauner raised five stages from freshman to expert, and each stage which people are moving forward to requires different knowledge: Know about orientation,general situation,and the contents of basic operation as well. The knowledge concerning to the occupation, that is to say ,people should assure how to connect this job with the other jobs, and consider the reason why such connection is needed. Specific and functional knowledge, which refers to knowing the contents involved in a certain specialized work and make sure how it works. The deep knowledge based on experience includes the investigation on how to explain the relevant jobs in systematically and the further development. Proceeding from the above stages,the learners progress in gaining the professional ability from freshman to expert is no more than a process from receiving information passively to more reflection and participation. Besides, the knowledge becomes more internalized as time goes on, which is nearly close to self-construction.( Smith,PJ.Smith,ES. 2006)  [3]   FreshmanÆ’Â  personnel with progressÆ’Â  adeptÆ’Â  skilled personnelÆ’Â  expert Billet and Mansfield present the definition of workplace learning from the angle of learning results of knowledge and skills etc. with the purpose of establishing a theoretical frame so as to summarize and distinguish each form of learning in workplaces and combine them with work of the employees. Blended learning in the workplace Blended learning in the workplace refers to the comprehensive learning activities performed by adults within the workshops for the solution of work problems and the adjustment to the new working environment, including blended working activities, learning activities, learning technologies and learning environment. Blended learning, the new term takes shape on the foundation of e.Learning reflection features effective combination of traditional learning methods and e. Learning, does not only avoid the disadvantages of traditional learning, but also absorb superiority of e.Learning(LeeZhao 2004)  [4]  .In recent years, there is an increasing number of professional managers and training supervisors in workplaces accepting the concept of blended learning and exploring to put its means into application in enterprise trainings as well as employees studying. Compared with single e.Learning, blended learning can increase training efficiency, reduce worker cost and decrease training periods(RossettFrazee 2006)  [5]  . Essence of workplace learning lies in blending, for instance, employees can pass on working experience through communication, learn technology through listening and observing colleagues and study new operating procedures by attending trainings. In recent years, an increasing number of managers and trainers in North American workplaces start to accept the conception of blended learning. According to the survey conducted by Sparrow in 2004 with the subjects of over 300 training professionals from countries such as America and Britain, more than 2/3 subjects believe that blended learning is the most effective training approach with the highest cost efficiency. Besides, it is forecasted that investment in blended learning will account for 30% of training budget in the companies in 2006. The final target and difficulty of blended learning, the integrated strategy of transferring learning and promoting performance that means dynamic integration of many approaches including combination of formal and informal learning, face-to-face and internet learning, teacher-instructed and self-tutored learning and the digital resource-assisted and aspectant communication and discussion learning, lie in improving studying and performance of the organization and selecting appropriate connections of multiple ways in accordance with specific situations and subjects respectively. Many American enterprises are conducting practice and exploration of blended learning, IBM, for instance, has designed and developed Basic Blue blended learning system applicable for the training of over 30,000 new managers that are globally distributed and constantly on the move, which consists of self-evaluation of online e-learning, online simulation of commercial scenarios, online communities, face-to-face tutor instruction as well as workshop discussion, synchronous/ asynchronous virtual collaboration tools (emails, telephones, instant messaging and electronic white board) and professional e-tutors etc.( RossettSheldon 2001)  [6]   It is obvious that blended learning is a good idea, but is it suitable for all organizations? It is more complicated than traditional classroom instruction at fixed time and in fixed places. In spite of the considerable consensus people have reached on conceptions, namely, significance of learning in workplaces deserves affirmation and its effect can not be ignored, it remains not enough to encourage enterprise employers to decide to increase investment budget in this area with the reasons that it might be a long-term investment career without producing any effects in a short period, meanwhile, it calls for enough and a large number of capital investment, which is only enough to shut some small and medium-sized enterprises out of door. As employers, the attitudes towards educational investment will eventually depend on what kind of investment can produce considerable output, which will on average make the enterprises caught in a dilemma. On one hand, major companies are convinced tha t learning activities can constantly satisfy the organizations demand for skilled labor force with comprehensive knowledge, which is conducive to enhance their competitiveness in the international market; on the other hand, we can not fully grantee that the expenditure utilized in employee learning and training is bound to create profits and benefits for the enterprises, especially that there exists a phenomenon of frequent job mobility among young employees owing to the function and influence of flexible market, and there is no doubt that they will take away with them all the knowledge and skills learned when they employee conduct resign and job-hopping, which means it is a movement of high risk for all enterprises, especially the small-sized and micro ones to overly invest in employee training. Take Denmark, the typical country as an example, on one hand, local enterprises on average are not willing to bear the education and training cost because people in Denmark are used to pay in a full manner the cost of continuing education and skill training by public finance, and they are not willing to pay the cost unless it is an education and training program of special significance for enterprises or employers; however, on the other hand, they have to admit that learning content, purpose and approaches in workplaces will indeed pose great influence on enterprises, and accordingly development and implementation of corresponding learning program is good for enterprise development. Therefore, investment in this part will be gradually increased in enterprises. As for that of general education, it will be decreased gradually due to the enterprises perspective that it will not produce direct economic profits. The above are the double attitudes towards learning produced by companies. Ho wever, they will positively prefer to introduce in quantity such learning into enterprises provided that workplace learning can enable enterprises to get some financial subsidies from other aspects. Learning island In Germany, the traditional dual training system is encountering unprecedented challenge. Many people are for the opinion that under the mode of dual system, enough attention has not been paid by vocational training to learning and training in workplaces, especially that professional trainings of large enterprises are generally purely consumptive skill trainings conducted by training workshops that are independent from the manufacturing process, which separates vocational training far away from practical production of the enterprises despite that it is conducive to the formation of fundamental skills. However, the significance of learning and training in workplaces is becoming increasingly prominent in modern training system. In addition, the capacity of learning and working in a team can not be taught, which requires the learner to learn as a member of the team. In order to change the situation, large corporations in Germany begin to explore training approach that is closely connect ed with the process of production in recent years, emphasizing learning in the working process. It is just under this background that the conception of Learning Island is introduced to the field of vocational learning and training in Germany. Learning island, which is a working area established in the actual production environment of a company, marks a component of real production process from whether the spatial perspective or the organizational one. That is to say, it enjoys the same working conditions and procedures for the solution of work and problems with actual production environment. In learning island, the trainees jointly accomplish a certain working task in the production process through cooperation in the form of groups and teams, and the productions they manufacture should meet the quality requirements, namely, they should enjoy economic value. Meanwhile, as the coach personnel, training teachers provide assistance about the problems and difficulties they encounter to the learners  [7]  . There are some learning islands establishing in Benz car plant in Gaggenau that are separated areas including producing and educating equipments in the working plant. In the unit of groups, learners there carry out work by taking projects as orientation with the content of scheming producing task, manufacturing certain parts and solving logistical problems. The productions manufactured need to go through quality tests and those qualified will be assembled to the cars. Work of the whole group will be supported by a coach who only coordinates and intervenes when it is necessary so as to maintain the initiatives of trainees. Each group is supposed to accomplish a specific work or task goal within five weeks, the process of which will be fed back regularly to relevant groups in order to encourage learners to seek improvements. With the purpose of providing help to learners in learning island, some employees from the front line of production will be selected by senior workers to take the duty of tutoring personnel, and the production losses resulted from absence of tutors from the first line of production will be fixed by groups in learning island, through which what their work means in an industrial or commercial environment will be confirmed by the learners. Only when serious mistakes happen can the tutors, who serve as contact points of work groups and play the role of advisor intervene with the purpose of maintaining self-governing of the group work as far as possible. Work-based learning The concept of work-based learning Boud, Solomon Symes describe work-based learning as follows: à ¢Ã¢â€š ¬Ã‚ ¦a class of university programs that bring together universities and work organisations to create new learning opportunities in workplaces. Such programmes meet the needs of learners,contribute to longer-term development of the organisation and are formally accredited as university courses. There is a wide variation in the mix of elements they include, ranging from little more than a lightly tailored version of an existing course delivered in the workplace with some work-related assessment activities to programmes which focus more closely on the needs of learning in work. At the more interesting end of the spectrum are those programmes which depart substantially from the disciplinary framework of university study and which develop new pedagogies of learning. (Boud, Solomon Symes 2001:4)  [8]   Work-based learning is designed to use the opportunities, resources and experience in the workplace'(Margham 1997:2)  [9]  . These programs link theory and practice and are underpinned by appropriate professional knowledge and reflective practice (Hunt 2000)  [10]  . Work-based learning can be organised in a variety of ways and often consists of a hybrid mix of activities, however, they commonly include students undertaking a project or series of projects in their workplace. The context of work-based learning The work-based learning is an important component in Dual System Vocational Education in Germany, which has also achieved development in Australia,America, England in recent years. The development of the work-based learning in Australia The work-based learning system is developed with the evolution of apprentice system and trainee system, which are powerful in Australia.In the past seven years,under the support of finance and fundamental training programs, there was a great increase in the number of youths and adults who participated in training programs in Australia. In 2000, the apprentices and trainees who were accepting training are 275,000(Smith 2002)  [11]  .To tell the difference between apprentice system and trainee system, we should have a brief review on the historical evolution of the training system in Australia.Before the mid-1980s,orientation training was the work of traditional apprentice system and involved limited occupations.The Kerribi Report in 1985 suggested a one-year trainee system should be set up for the youths at the age of 16,17.In this system, 20% of time was used in school-based learning, while 80% of time was in work-based learning and the trainees also could receive 80% of the sala ry.People who participated the training in apprentice system were called apprentice, and in trainee system were called trainee.During 1996 to 1997, the number of trainees surpassed that of apprentices for the first time. Australia officials have ever expected to merge these two systems, and hoped to use Australia Vocational Training System,Modern Australia Apprentice System and New Apprentice System to unite the old names.But in fact , it is difficult to tell the difference between apprentice and trainee in Australia. Generally speaking, apprentices training time is longer than two years according to contract, otherwise, is trainee. Whatever in apprentice system or trainee system, the core part is the work-based learning. The development of the work-based learning in America In the late 1980s and the early 1990s, some areas and school districts or schools have noticed the problems in education so they launched reforms in local areas ,began to introduce the work-based learning and formulated various of models. For example, Georgia stipulated in its legislation in 1992 that any students in the grade of 11,12 or at the age of or more than 16 years old can register one of Youth Apprentice System programs provided by public schools(Smith 1998)  [12]  .A part of these models was adopted in School-to-Work Opportunity Act (STWOA) of 1994 and was spread through government. 3.the development of the work-based learning in England The work-based learning of England is reflected in the modern apprenticeship. The traditional apprenticeship was collapsed dramatically in 1970s. The main reason is it had little relation with mainstream educational system. In order to bridge the gap in training employees, the British government carried out a series of vocational training plans from the late 1970s to the late 1980s , however, its youth training plans didnt launched until 1990, and did not achieved success as hoped. Therefore, the British government initiated modern apprenticeship in September 1994. The early modern apprenticeship was applied in 14 industrial departments, and since 1995, its aim was to applied it in all industrial departments.There are three interrelated aspects in British modern apprenticeship:(1)apprenticeship is operated within the framework of contract which stipulates the rights and obligations of employer and apprentice explicitly and detailedly.(2)it includes cultural and social aspects before work and during the working process.(3)it contains school-based and work-based learning system which is an important characteristic of post-war British enterprises apprenticeship.Thus,the work-based learning is also the center of the British apprenticeship. The development of the work-based learning in worldwide has proved that it is a valuable and novel learning form in the recent vocational education and it is fully reflected the practicality of vocational education.At present,the extent of the promotion of the work-based learning is different in varied countries.For example,apprenticeship never plays an important role in cultivating skills in United States.And the 1990s modern apprenticeship did not gain the expected success in rebuilding the descending traditional apprenticeship in England. Compare to US and England,Australia was successful in this. Conclusion and Reflection Through the literature review,I have learned that Workplace learning is more than having structure,but a complicated one.However, due to the influence by too many elements,very few people can have full insights into the identity of work and learning and make natures of the two,with respect to learning or work,influence and supplement each other.Instead of maintaining an unchanged state in the whole interning process in workplace learning,the constantly changing environment, individual and different development demands of learners and the formed learning motivations will present a fluctuation in different occasions.Learners are also workers,and vice versa,so as to realize the required role coordination.The workplace-developed knowledge,which is primarily practical one under specific situation, is not public and can be structured only with experience.As a result, experience and reflection serve as its core elements, and it is of great significance for the individuals to participate in the practical process.Workplace learning, which marks a learning activity with instruction owing to the fact that it call for not only initiative as well as independent activity with abundant sense of responsibility, but also instruction and demonstration of experienced workers, allows learners to consolidate their own capacities through more practical operations and expend them with the organic combination of marginal participation and guidance. Everyday work activities when effectively structured provide opportunities for accessing and constructing robust and transferable vocational knowledge.The qualities of workplaces most likely to secure this knowledge are those that structure activities which assist individuals to move from peripheral activities to those which are more central to the functioning of the particular work practice;that provide expert guidance which presses individuals into accessing more complex forms of knowledge and which explicitly illuminate that which is not readily revealed. Through the literature review that I know how design of workplace learning mode for enterprises, guide and instruct workplace learning in an effective manner in order to achieve ideal learning effect of workplace learning, satisfy employees demands of career development and individual growth as well as coming to an agreement with business goals.The workplace is now commonly used as a setting for acquiring vocational knowledge.This situated approach to learning offers access to authentic vocational activities and the guidance of more expert others . Experience is most easy to grasp in practice.So,sharing experience is also a learning.Workplace learning is taught by one person who have experienced to no experience.Interest is the result of the learning experience,learning experience will impact personal education in the future and the development of vocational skills.Although the experience is the base of learning,but without reflection,learning is not complete.In fact,if the individual does not reflect on the experience,or did not consciously learn from experience,the experience of individuals may not learn.

David Livingstone :: essays research papers

David Livingstone is a Scottish missionary and physician. He spent most of his life exploring Africa. He helped Europeans learn a lot about the continent of Africa. Livingstone was born in Scotland. His parents were really religious so David followed his dad’s footsteps. David is a really hard working person, the reason why he would want to go to Africa was because he knew that there weren’t a lot of Christians there; he also knew that not many people there knew about Christ. At age ten he began working in the local cotton mill, he had to work long hours and he got too little pay for what he was doing. When he didn’t work, he would just stay at home to study, and in 1836 he entered Anderson's College in Glasgow. He was mainly interested in theology and medicine. In 1838 the London Missionary Society accepted him as a candidate, and two years later he received a medical degree from the University of Glasgow. The First War between Britain and China ruined his hope s of becoming a medical missionary to China, but the missionary society arranged a new placement for him in southern Africa. He was supposed to be preaching in the southern part of Africa; however, due to the fact that he wasn’t successful, he went to the north. While he was there, he worked with an individual named, Robert Moffat. Later on he married his daughter, Mary Moffat. For the next 15 years, Livingstone was constantly moving into the African interior. He was strengthening his missionary determination he was also responding entirely to the delights of geographical discovery; he was building for himself a Christian, a courageous explorer, and a fervent antislavery advocate. As a missionary, David Livingstone quickly believed that what he was supposed to do is to not remain in one spot, preaching the gospel to the few local people willing to listen. Instead, he should keep on moving, reaching new groups and extending to them to be more familiar with what God wanted them to do with Christianity. Eventually he would expand this idea into a belief that his role was to open up Africa's interior to broader influences from Western civilization. Once that occurred, he would work hand in hand to end slave trading and uplift African peoples. Such motives drove Livingstone. He worked really hard as a missionary but he still had the desire to keep on exploring.

Akron Zoo :: essays research papers

External Environment Like any other organization, Akron zoo is effected by many external environmental factors that may directly affect its yearly attendance and its ability to break even to continue to operate. The first externality that the Akron zoo faces is the climate. Because most zoos operate out in the open, its attendance is affected directly to the weather. Due to its northern climate, the zoo conducts its open season from mid-April until mid-October. Variations in weather also affect crop yields and prices of fresh animal foods, thereby influencing the costs of animal maintenance. Unfortunately, the Akron zoo can not do anything about the weather. The only other option it may have would to be to open more indoor activities, but that would be too high of a cost risk because the payback may have not been worth the construction in the first place. Zoo’s still remain as important part of any community and to the hearts of young children every year. It is estimated that more people annually visit zoos than enter all U.S. national Parks and that approximately and that 35% of people who attend zoos are adults. Cultural events that happen in the city of Akron and nearby areas help increase attendance at the parks. The biggest cultural event in Akron is the annual Snow Bowl. Not only does this event help increase attendance, In its 12-year history, Snow Bowl has raised over $388,000 for the animals at the Akron Zoo. Other events such as the annual Nocturnal Golf Tournament, annual birds seed sales and annual Sunday Sundae Zoobilation have huge effects on zoo attendance on the day/weekend of the events. On weekends where cultural events are going on, the Akron Zoo should try and sell items that would attract people who are visiting such as having certain products directly affiliated to the Snow Bowl at a slightly higher price that out-of-towners would be willing to pay for. Akron is located just south of Cleveland, Ohio.

Harmful Algal Blooms and Aquaculture

Harmful Algal Blooms and how they are Linked to Aquaculture Abstract Harmful algal blooms cause a wide range of negative effects on aquaculture. These effects are come from the complexity of harmful algal species; the toxins they create and morphology they have adapted. Science still lacks a full understanding of factors that are envolved in blooms formation. Aquaculture and harmful algal blooms are directly related because it is one of many anthropogenic factors that unintentionally produce the conditions that promote harmful algal blooms.The methods of production, feeds used, waste produced can lead to nutrient loading and eutrophic conditions by releasing essential nutrients into water that are necessary for algal growth. Phosphorus and nitrogen compounds are two of the main byproducts or aquaculture that are associated with bloom formation. To minimize the effects of harmful algal blooms on aquaculture you must understand the diversity and complexity of harmful algal blooms and t heir relationship with aquaculture.

Andrew Blajda Introduction Over the last several decades harmful algal blooms events or HABs are believed to be increasing in frequency and geographic range. The reported increase is a major concern because of the wide scale impact they have on he environment and human activities. The effect of HABs on aquaculture can be very damaging with reduced growth, mortalities or accumulation of toxins. If aquaculture operations take place in the open bodies of water they have little or no way of avoiding incoming blooms. Harmful algal bloom events that come in contact with aquaculture operations often have negative effects that can include student growth, weakened immunity, mortalities, and on economic losses.One of the bigger concerns today is the apparent increase in harmful bloom events. Researchers have linked this increase with anthropogenic activities, aquaculture being one of them. Aquaculture operations adds additional nutrients to the system, this lowers nutrients that l imits algal growth. A better understand of the dynamics and characters the form and make up a bloom combined with the a better understanding of nutrient loading of aquaculture could potentially help reduce the negative effects harmful algal blooms have on aquaculture.Single celled microscopic algae like phytoplankton are the most globally abundant species and one of the oceans’ most important resources. These autotrophic primary producers form the bottom of the food pyramid, acting as the primary source of food for larval finfish, crustaceans, filter feeding bivalves, and other species (Hallengraeff, 1995). In normal concentrations, these single celled algae work in balance with the ocean and its inhabitants, filling important roles in chemical and nutrient cycles. They act as primary producers, providing nutrients and food for variety of different species.These simple microscopic species are vitally important to the success of both fisheries and aquaculture, but in some situ ations they can also have detrimental effects on the marine and coastal environment and numerous terrestrial and marine species. A combination of physical, chemical, biological, hydrological, and meteorological events can generate appropriate conditions that allow these simple single celled microalgae can exhibit exponential growth and reproduction. These natural events create the opportunity for algal bloom formation with potential large scale negative effects throughout the area they cover (Graham, 2007).Algal blooms can be very diverse and differ from one another in many ways . How they form, the algal specie of causation, characteristics and dynamics of a blooms, the species they affect, and impacts they cause are some of the complex factors that are found in blooms (Zingone & Enevoldsen, 2000). The specific characteristics used to define a harmful bloom vary by sources. Hans Paerl, among others, defined harmful blooms by using several characteristics. Paerl also defined harmful blooms at their most basic level by classifying them as having nuisance conditions, meaning ecological and/or economic impacts (Paerl, 1988).As harmful algal blooms move across the ocean, the observable effects they cause go beyond the ocean and marine species it covers. These events will also have wide spread negative impacts on costal terrestrial organism and both human health and activities. Algal species produce sevral different toxins that are detrimental effects to human health, causing various illnesses and mortalities. About 10% of foodborne disease in the United States results from algal toxins; worldwide they cause more than 60,000 intoxications a year. Van Dolah, 2000) Economic losses due harmful algal blooms have been estimated in the tens of millions of dollars, from costs of beach clean ups, decreased tourism, and closing or stopping sales of commercial fisheries and aquaculture (Van Dolah et al. , 2001). Over the past several decades there has been an apparent increa se in the frequency and geographic range of harmful algal blooms. This apparent increase has been attributed to both increased observations and focus on harmful algal blooms and increased inputs from anthropogenic sources.Aquaculture is one of many anthropogenic activities that is believed to be hypernutrification and eutrophic conditions in surrounding bodies of water. This paper will attempt to gain a better understanding of diversity of harmful algal blooms and also the effect aquaculture has on the environment in adding in formation of harmful algal blooms. Algal Blooms Historically algal blooms are a naturally occurring phenomenon in earth’s oceans and have been observed throughout recorded history (Hallegraeff, 1993).These events are often beneficial to bivalves by supplying an abundant food supply to these filters feeding that relay on microalgae for their source of nutrients. Algal blooms can quickly turn into detrimental to the environment and its inhabitants are var ious ways (Leverone, 2007). Sources from human history including the bible may contain the first documented cases of algal blooms. In Exodus 7: 20-21 referring to one of the plaques on Egypt â€Å"all the waters that were in the river turned to blood, and the fish that was in the river died†.Some historians and scientist now believe this biblical reference from 1,000BC could be the first written record of an algal bloom. (Hallegraeff, 1993) Other historical sources may have unknowing recorded written evidence on algal blooms, in China around 200AD general Zhu Ge-Ling documented sicknesses and losses of military personnel after drinking from a river that was stained green. (Chorus & Bartram, 1999) Examination of fossil algal specimens and historical reference compounding evidence that these event are not a new phenomenon and have been occurring in earth’s oceans for thousands if not millions of years.Recent finding from numerous long term studies conducted around the wo rld has brought a strong belief in the scientific community that algal blooms have been increasing in their frequency and geographic distribution. Even though most scientiest support the idea of a global increase of blooms and twith strong evidence supporting this theroy there is still a major dissagreement about what is causing the increase (Pelley, 1998). The apparent increase of algal blooms, along with the global impacts on aquatic organisms, the environment, human health, and activities has increased interest and research being done on these events (Li et al. 2002; Van Dolah et al. , 2001). The exact characteristics and descriptions that define an algal bloom are fairly broad and very from source to source. I was unable to find a universal definition of algal blooms. The description and definition I came across were similar but differed in many aspects; this included sizes, formation factors, impacts, and algal species. Overall algal blooms are generally defined significant inc rease in biomass due to a rapid reproduction of a single microalgal species.The problem with this source is there can also be macroalgal blooms. Others described them as forming high density populations, with some species creating visible discoloration of the water. (Carstensen, Henriksen, & Heiskanen, 2007; Diersing, 2009) Others define blooms by impacts they cause; displacing indigenes species, destroy habitat, oxygen depletion, and alter biochemical cycles. (Hoagland et al. , 2002) A more generalized definition was given by Hallegraeff, adding that a bloom must have at least million cells per liter (Hallegraeff, 1993).The defining characteristic that differentiates a bloom from a harmful algal bloom is when they takes on a destructive roll and causes environment impacts. The term harmful is defined more specifically as causing negative impacts on the environment and adverse effects on both aquatic and terrestrial organisms. This is due to factors such as toxins they produce, spec ie specific cell physical structure causing damage to aquatic organisms or by accumulation of biomass affect naturally occurring organisms causing alterations food web dynamics and biochemical cycles (Anderson et al. 2002). Depending on the species, some algae produce toxins that can affect crustaceans, fish, shellfish, birds and mammals including humans; nontoxic species can still causes damage by blocking light from penetrating the water column, clogging or damaging gills, and creating anoxic conditions from accelerated decomposition as they die off (Silver et al. , 2006; Sellner et al. , 2003) Harmful alga can also have impacts on shoreline coastal habitats, toxins can be transported onto the shore by sea spray (Hoagland et al. , 2002).There are over 5,000 know photoplanktonic algal species that inhabit the marine waters only a small portion, about 300 species are known to have blooming capabilities and even fewer, about 40-80 species or 2-3% of all photoplantonic algal species a re known to have toxic chemicals producing capabilities; this includes members that form red tides (Hallegraeff, 1993; Smayda, 1997). Nontoxic red tides are not uncommon, today people often incorrectly or mistakenly refer to toxic algal blooms as red tides even when brown, green or colorless (Anderson, 1994).Toxic and other harmful algal species are ubiquitous throughout the marine and freshwater environment; the majority of the time they present at low population densities that cause few, if any and only minor impacts on the environment and its local inhabitants (Van Dolah, 2000). There are a variety of different phycotoxins algal species are able to synthesize; individual species will only produce one type of toxin. The evolutionary advantages of these toxins are not fully understood; they are believed to play a role in bloom formation and predator protecting (Nehring, 1993).The different phycotoxins vary from one another in terms of the impacts and degree of damage they have on m arine and terrestrial organisms, depending on the toxicity, the concentration, and the organisms. Toxicity vary among algal species Dinophysis is one example, they have the ability to produce toxins that have negative effects at densities as low as 100 cells per L-1 (Sellner et al. , 2003). The most toxic algal species are mainly found in dinoflagellets (Table 1) with some having toxicity greater than venomous snakes. Table 1.Toxicity of several phycotoxins created different organisms including algae. (Van Dolah, 2000) The taxonomic algal groups’ dinoflagellets, raphidophyetes, cynobactria, and some diatoms are known to have the capabilities of phycotoxins production; these species are often the culprit behind harmful algal blooms. Phycotoxins are toxic chemicals created biologically by photosynthetic organisms. Dinoflagellets are one of the predominate species that forms red tides; members of this group also produce toxin that lead to foodborne illness and human mortalities (Li et al. , 2002; Hallegraeff et al. 1995). Human induced illnesses are not an uncommon result from consumption of seafood. Many algal toxins are potentially dangerous and even deadly to humans. Toxins accumulate in tissues of organisms like shellfish, finfish, and crustaceans that come in contact with a toxic bloom. These species are usually far less affected by algal toxins having adaptive mechanisms that lower the effects on the organisms associated with toxic blooms. However toxins still accumulate within the tissues and detoxification can take weeks before they reach levels safe for human consumption.Algal toxins cause for concerns for humans not only because they maintain their toxicity long after the bloom but more importantly because they can withstanding heat from cooking. Algal toxin foodborne diseases are caused by various species or toxins and come from different vectors. Bivalve vectors can induce human illness that include (Table 2) paralytic shellfish poisoning (PSP) , neurotoxic shellfish poisoning (NSP), amnesic shellfish poisoning (ASP), diarrhetic shellfish poisoning (DSP); other vectors can lead to various other diseases as well (Van Dolah, 2000).The popular term of red tide given to harmful algal bloom comes from compact, high densities of algal cells that containing red photosynthetic pigments, causing the water to appear red (Carstensen et al. , 2007). These toxic species can normally be found in low concentrations have no impacts on organisms and environment. The adverse effects on organism often deepened on cell concentration; in blooms toxic algae aggregate and are more dangerous (Van Dolah, 2000).Some toxic algal species have developed unique life cycles and morphological characteristics that allow them to occupy a specific niche that will be further examined. Table 2. Foodborne and environmental disease caused by harmful algal species, the toxin produced and the primary vector they inhabit. (Van Dolah, 2000) Harmful algal species ha ve many adverse impacts on bivalves’ this includes a wide range of sub-lethal and lethal effects; some algal species are more detrimental than others (Leverone, 2007). It is believed that increase frequency of blooms is partially due to the introduction of non-indigenous algal species.Non-indigenous species potentially will create a specific niche, and/or out compete native species. Indigenous naturally occurring harmful algal species are far less direct effects on bivalves; this is because they have been able to naturally adapt to their presence over time. Native algal species in most case do not have as bad direct, detrimental impacts on shellfish and are usually not associated with large scale bivalve die off. The exception to this is in cases of intense blooms (Matsuyama & Shumway, 2009; Nehring, 1993; Zingone & Enevoldsen, 2000).It’s still hard to truly say many large scale die-offs and increase sub-lethal impacts are directly due to non-indigenous algal species b ecause identification is sometimes difficult, longer term data individual algal species geographic ranges are limited combined, and the theory anthropogenic factors are causing an overall increase in blooms. In many circumstance of HAB mortalities it’s difficult to differentiate whether they resulted from the algal specie or unfavorable water quality that coincide with blooms (Anderson et al. , 2002; Leverone, 2007).Complex morphology are found in many harmful algal species that helps protect them from predation and the environment and help obtain nutrients. Diatom algae are members of the Bacillariophyceae class; they have been around for over 180 million years helping to create earth’s atmosphere and also play a major role in nutrient and chemical cycles. Over their evolutionary history diatoms have developed a variety of different exterior cellular morphology for protection from the environment and predation. They have a range of cell shapes and sizes and also form unique frustule cell walls made from silica.The frustule cell wall is made up of two over lapping overlapping silica bands forming a protective shell. The 100,000 diatom species have developed â€Å"seeming infinite variations† of cell wall micropatterns and structures; including ridges, spines and plates (Kroger & Poulsen, 2008) These cellular morphological characteristics help protect them under adverse environmental conditions and restrict or prevent predation. Some species of diatoms have developed such strong cell walls with structural properties that enable them to survive ingestion and escape after passing through the digestive system. (Merkel, et al. 2003) The benefits of these structures do have negative effects and come at the expense of motile abilities, limits growth, and makes the cell very dense; motile restorations and high cell densities make diatoms much more likely to sink out of the high nutrient water column. Bloom Formation The intricacy of bloom formatio n is due to both the abiotic(environmental and anthropogenic factors) and biotic factors; these being the algae themselves. Adaptations of life cycle, morphology, and environmental conditions enable rapid reproduction of certain algal species that have developed specific niches (Sellner et al. 2003; Zingone & Enevoldsen, 2000). Algal blooms formation driven by the complex relation between the environmental factors and algal species; although we understand the basics of formation there are still many unknowns. There are seemingly endless amounts of variables and factors that play a role in creating of a bloom. The main driving factors of when and where a bloom forms are a combination of environmental/anthropogenic factors (nutrient cycles and inputs) and algal morphology (Pinckney et al. , 1997; Sellner et al. ,2003).As simple as it sounds, there are countless variables including natural condition, anthropogenic effects, algal physiological and morphological characteristics that lead to the unpredictability and overall misunderstanding we still have on blooms. (Sellner et al. , 2003; Anderson, 1994) The belief that algal blooms are increasing in frequency and geographic range is a popular belief that is backed by numerous studies. The cause of this apparent increase has been attributed to the expanding human population (anthropogenic effects).Some still argue that the increase in blooms is due to the increase in observations from studies worldwide, a better understanding of blooms and better record keeping; but with overwhelming evidence supporting the lateral it’s hard to believe the human race is not playing a major roll. (Sellner et al. , 2003) Looking at the numer of literary reference to harmful algal bloom over 70 years(figure 1) shows a dramitic increase algal blooms from the 1920’s through late 1990’s (Hallegraeff, 1993). This also give arguments that increase research and technology contriubute to the increase ovserevd.Figure 1. Li terary references of harmful algal blooms from Aquatic Sciences and Fisheries Abstract (AFSA) publications over about 70 years. The increase can be attributed to a combination of anthropogenic factors or increased observations and present arguments for both sides. (Hallegraeff, 1993) Today we have an understanding of the natural environmental processes and factors that lead to bloom formation; but the effects humans apply to the environment alter the natural cycles making it more difficult to predict blooms (Paerl, 1988).Blooms occur under irregular conditions that promote growth and reproduction allowing some species to flourish. The conditions found in blooms broad and often species’ specific adding to the complexity and unpredictability of blooms. In general the conditions associated with blooms are abundance (eutrophic), or an imbalance of nutrients, along with favorable water conditions (temperature, DO, salinity, etc. ). Natural processes like atmospheric deposition, wa ter column turnover, upwelling, oceanic currents, storms, and anomalous weather events (El Nino) work together and fluctuate over time effecting mixing rates, water quality.Nutrients pools build up over time from organic decomposition in benthic sediment. Mixing of the sediment perelapses the nutrient pools and bring about eutrophic conditions or alter the water chemistry that enable specific species of algae to flourish (Sellner et al. , 2003; Van Dolah, 2000; Paerl, 1988). Natural mixing rates occur during regularly during temporal or seasonal with environmental fluxes or randomly from disturbances (natural anthropogenic). Sediment mixing are very important environment processes, releasing nutrients back into the water column allowing for increased primary producer growth.Seasonal and temporal sediment mixing produce lead to the specific conditions that form blooms. Eutrophication has been defined as â€Å"an increase in supply of organic matter to the ecosystem; in terms of alga l bloom this refers to an increase in nutrients that allows an increase of primary production† (Bonsdorff et al. , 1997). Three key nutrients, nitrates ammonia and phosphates are associated with eutrophication and considered the driving forces behind bloom (Sheng, Jinghong, Shiqiang, Jixi, Dingyong, & Ke, 2006). The levels found in marine waters are driven naturally based on natural events discussed above.Studies have found a correlation between anthropogenic actives leading to nitrogen and phosphorus nutrient loading and the apparent increase in frequency of algal blooms along with alteration of natural nitrogen/phosphorus ratio (Bonsdorff et al. , 1997; Paerl, 2009). There are various anthropogenic activities that have led to the both local and global increase of nutrients in fresh and marine waters. Aquaculture is just one of many of these activities. Many studies have shown that aquaculture operations have byproducts that can cause eutrophic conditions.Nutrient loading fro m aquaculture only has local effects and the amount of effects it causes is size dependent (Anderson et al. , 2002). Aquaculture and Nutrient Loading It is important to understand the relationship between aquaculture and harmful algal blooms. Additional nutrients from the feed used, effluent discharge, and waste products are some of the source that lead to nutrient loading (Tacon & Forster, 2003). The amount of additional nutrients added to a system increases based on how intensive the operation is.HABs have wide spread negative impacts on aquaculture, the hope of significantly minimizing these impacts are still years away. To minimize the effects on aquaculture you must understand characteristics and dynamics of blooms, this includes the diversity of species involved and the factors associated with bloom formation. The apparent increase frequency and geographic range of harmful algal blooms is very important to aquaculture because aquaculture plays a role in helping create the cond itions necessary for bloom formation.Aquaculture operations provided year round nutrient inputs in a local aspect, this eliminates nutrient limitations in those areas (Bonsdorff et al. , 1997). This section will discuss and review the relationship aquaculture has with nutrient loading and eutrophication of the surrounding water. Nitrogen and phosphors are to key elements that take on various forms necessary for bloom formation. Both nitrogen and phosphors in the forms of nitrates, ammonia, phosphates and other compounds are byproducts of aquaculture.Algal growth is limited by nutrient availability, mainly based on availability of nitrogen and phosphors in the environment. Nitrogen in the forms of nitrates and ammonia are water soluble and enter the system from either dissolved feeds, effluent discharge, or from waste produced by fish. Phosphates often accumulate mainly in the sediment and during mixing events are released into the water in high quantities (Karakassis, Pitta, & Krom, 2005). Nutrient loading from aquaculture that leads to eutrophic conditions come from several sources. The amount and source of the nutrients depends on the operation.Location of farm (open ocean, ponds, raceways etc. ), what is being cultured (shrimp, finfish, bivalves), what are the inputs (feeds, fertilizer, etc. ) and how intensive the operation is. The source of local nutrient loading from aquaculture can be traced back to where the operation is taking place. Open ocean farming of finfish for instance causes eutrophic conditions right around the cages. On the other hand inland facilities such as pond systems and other flow through systems release effluent discharge causing nutrient in the and around the bodies of water they run into.The species being cultured also plays a major role. Bivalves for instance play a role in limiting algal growth by filter feeding, while finfish inputs and excreting essential nutrients in their waste is a major source of nutrients (Soto & Mena, 199 1). How intensive an operation is and the actual inputs into the system are directly related. The more intensive an operation the more inputs and the more inputs the greater chance of hypernutrification and eutrophic conditions. Different operations require different inputs and these inputs have different nutrient atios. Culture of some juvenile finfish require fertilization to promote phytoplankton growth for feed this puts the essential nutrients for algal growth directly into the system. The feeds used in aquaculture vary on the nutrients they are made up of, how stable they are and whether they float or sink. These factors are all in play in nutrient loading that come directly from aquaculture (Islam, 2005). The effects of aquaculture feeds on nutrient loading depend on several factors. There are three main factors these include; 1) the amount of wasted feed.This is due to poor farming and management practice and floating Vs. sinking feeds. Poor management practices means over o r an improper feeding technique that puts more feed in the water. Floating and sinking feed choices is also important. Sinking feeds may not be eaten by finfish if they go through the bottom of a net or cage, or if they sit on the bottom. On the other hand floating feeds may be less stable or uneaten if they are transported out of a system or to a place where they are unable to be eaten. 2) The actual quality of the feed.This poor stability and high solubility of feed pellets in water mean that once they are in the water they will be broken down and release more and nutrients and in less time. The final factor is deals is loosely related to the previous two. 3) Once the feed is ingested factors such as limitations of absorption and retention of the nutrients from the feed. This factor deals mainly with poor digestibility or metabolism of the species being culture to the feed they are given. The nutrients in the feeds many not be utilized to their full potential once ingested fish wi ll excrete the excess nutrients (Soto & Mena, 1991).Feed and nutrient inputs play a major role in nutrient loading and creating the conditions that promote algal growth either directly in the form of uneaten feeds or nutrients leaching or dissolving from the feeds, or indirectly from the digestion, metabolism and waste products from the species being cultured (Tacon & Forster, 2003). The important of feeds in nutrient loading must not be overlooked one study estimated that 70% of phosphorus and 30-50% of nitrogen in feeds is not utilized by fish and is released into the environment (Soto & Mena, 1991).This only shows two of the most essential nutrients associated with bloom formation and not the various other nutrients that are also released and are important for algal growth. This also shows the significance of feeds based on the large amount of nutrients that are not utilized and instead entering the environment, promoting algal growth. Over all aquaculture farm operations lead to excessive amounts of inorganic and organic fertilizer, feeds, and wastes that are put into local water bodies with high concentrations nutrient, that lead to nutrient loading and eutrophic conditions.Discussion and Conclusions Aquaculture over the last several decades has grown globally in both its production and popularity. In the future aquaculture will continue to grow in its importance to the human population as alternative food source to agriculture and wild fisheries, as well as helping with the depleted ocean stocks. As of now it appear that we will be seeing an increase in aquaculture around the world in the years to come. Although there are many benefits to aquaculture and the potential of increased production may have we must measure the benefits against the environment impacts they cause.Nutrient loading is just one of the environmental impacts associated with aquaculture and the effects of nutrient loading go beyond promotion of algal blooms. The global increase in aqua culture coincides with the apparent increase in harmful algal. Although there are many other anthropogenic factors that are at play in global nutrient loading aquaculture is a major local point-source form. We must understand the specific conditions that are associated blooms and the role aquaculture plays along with how complex and diverse blooms can if we hope to develop mechanisms that can significantly reduce the impacts on aquaculture.I choose the topic of harmful algal blooms and aquaculture effects of nutrient loading because it fits in perfect with our class: aquaculture and the environment. The purpose of this paper was to gain a general understanding of harmful algal blooms, and also to review the factors of aquaculture that lead to nutrient loading, eutrophic conditions, and the aid in bloom formation. This topic caught my attention because of similar topics I’ve cover and work I’ve done this semester in this class and others classes.Harmful algal blooms in general are very interesting because of the diversity of blooms, the range of effects they have, how unique the species involved are, and because of the complexity and over all lack of understanding have in factors of bloom formation. The purpose of this class included reviewing the impact of aquaculture on the environment and methods of reducing or eliminating those impacts. This paper focuses on harmful algal blooms and how aquaculture creates conditions that promoted bloom formation.I focused a great deal of this paper on harmful algal blooms because if you hope to minimize the impacts they cause you must appreciate and understand their complexity and also understand the relation they have with aquaculture. The purpose of this paper was not to examine direct ways in which to minimize nutrient inputs of harmful algal blooms but the information given on harmful algal blooms and the role aquaculture plays in promoting bloom formation is useful to future studies and reviews focusing on ways to minimize the impacts of HABs on aquaculture and help reduce the factors of aquaculture that promote harmful bloom formation.Bibliography Anderson, D.
