Research Sources Essay 1. Genes, Behavior, and the Social Environment : Moving Beyond the Nature/nurture Debate In the midst of the twentieth century, staggering steps were made in decreasing disease and upgrading the soundness of individuals and peoples. General prosperity measures, sanitation, improved cleanliness, and antibodies incited genuine diminished in mortality and dreariness. Extended insightfulness with respect to the dangers of the workplace realized decreased injuries and better prosperity for experts. Advances in bio remedial examination had any kind of effect develop learning of affliction and nudged the change of new clinical and pharmaceutical meds. More starting late, the sequencing of the human genome has given information that holds the surety for further upgrading human prosperity. During the time a broad accumulation of proof has created showing that social and behavioral components, for instance, monetary status, smoking, eating schedule, and alcohol usage are key determinants of prosperity. Late studies in like manner prescribe that breaking down joint efforts among innate and social-regular components could fundamentally enhance perception of prosperity and illness. In a study showing how the social environment can affect natural response, found that the money related status of gatherings is associated with mixtures in central tactile framework serotonergic responsivity, which may have recommendations for the power of mental issue and practices, for instance, misery, incautious ill will, and suicide. While examine on the impact of coordinated efforts can encourage the cognizance of ailment peril and help in the change of effective pharmaceuticals to upgrade the quality of individuals and masses, there is an absence of investigation that encompasses each one of the three regions. Much stays to be got some answers concerning how these variables work together to impact prosperity, including the most vital thought of portraying association and how it can be depicted. Since more conspicuous etiological perception is relied upon to perceive future clinical research and make convincing meds went for improving prosperity comes about, the board fixated its attempts on etiological examination. 1. Regulation of Gene Editing Activity Directed by Single-Stranded Oligonucleotides and CRISPR/Cas9 Systems. The reengineering of mammalian genomes is a capable hereditary way to deal with both comprehension quality  capacity and growing new treatments for acquired maladies. While the conventional endpoint for hereditary building has been to disturb or debilitate a quality through complete knockout, it is presently conceivable to direct single nucleotide trade in a viable and proficient way. Quality or genome altering can be catalyzed by a progression of atomic apparatuses that when utilized in different mixes precisely change the arrangement of the DNA in a site-particular style. Single-stranded DNA oligonucleotides (ssODNs) have been utilized for a long time to build nucleotide changes in the genomes of numerous living beings. Also, while the instrument of activity furthermore, the administrative hardware are being explained, in any event partially, the low effectiveness with which single-stranded oligonucleotides work in segregation has since a long time ago hampered their advancement for helpful application. As a quest for adjuvants that can improve the recurrence of singlestranded ODN–directed quality altering has continued, it was resolved that the twofold stranded DNA breaks actuated preceding the presentation of the single-stranded ODN raised the general action of quality altering. 1. Engineered DNA-Binding Proteins for Targeted Genome Editing and Gene Regulation http://nrs.harvard.edu/urn-3:HUL.InstRepos:11156806 The engineereed DNA-tying proteins empower focused on control of the genome. zinc fingers are the most all around portrayed DNA-tying space and for a long time examination has concentrated on understanding and controlling the succession specificities of these proteins. as of late significant advances in the capacity to architect zinc finger proteins and also the revelation of another class of dna-tying spaces interpretation activator like effectors have made it conceivable to quickly and dependably design proteins focused to any grouping of hobby. The capacity to explicitly alter the genome has incredible potential for examination and restorative applications. the homology coordinated repair in a mixed bag of cell sorts and creatures this strategy has never been utilized to right an illness bringing about transformation in human affected pluripotent undeveloped cells. the human b troll locus to remedy the sickle cell sickliness transformation. Every one of us acquire a large group of more subtle destructive changes. Maybe you are more inclined to experience the ill effects of coronary illness, certain tumors, dementia or emotional sicknesses, or to lose your sight or go hard of hearing in seniority. Whats more, your youngsters and your kids and every one of their relatives will acquire a large number of these transformations, alongside the new ones created as natures irregular slips proceed. When you see how these changes come to fruition, the case for assuming responsibility of our hereditary fate appears to be unanswerable. We are getting the capacity to free ourselves from the things of 4 billion years of thoughtless development. Germ-line hereditary designing obviously has threats, not slightest its capability to be utilized for the wrong purposes or the potential for its expense to limit its points of interest to the affluent. In any case, numerous stresses are overstated we couldnt design Einsteins in the event that we needed to, for occasion, on the grounds that we havent discovered any quality variations that have a remarkable effect to knowledge, regardless of much attempting. What we could do is end a gigantic measure of affliction. Whats more, in the event that it is accessible to everybody, not simply the rich, hereditary building could even help make the world a much more pleasant spot. 1. Chinese researchers alter embryo DNA: Do results cross ethical tripwires? Christian Science Monitor. 4/24/2015, pN.PAG. 0p.  humankind is confronted with the crucial inquiry of whether people ought to have this level of control over their own particular physical fates, says Alta Charo, an educator of law and bioethics at the College of Wisconsin at Madison. Were hitting the point where individuals are asking: Would we truly like to have the force not quite recently to choose among the decisions given to use by nature, however to make totally new decisions we  could call our own detail? The moral concerns encompassing hereditary control of conceptive cells are weighty to the point that numerous researchers and bioethicists are asking associates to start substantive discussions with partners, biotech-industry pioneers, controllers, vested parties, and people in general to make sense of what clinical uses, if any, future worthy. Others, incorporating some in the biotech business, contend for a ban on any germ-line exploration including human regenerative cells. One measure of the moral minefield into which the Chinese group walked: Two of the most high-perceivability science diaries, Science and Nature, declined to distribute the outcomes on moral grounds, the ventures lead researcher, Junjui Huang, disclosed to correspondents from Natures news division. A hefty portion of the starting concerns in established researchers include wellbeing and adequacy for a device they see as having possibly capable restorative applications. The Chinese group shares this worry and refers to its own outcomes as confirmation that CRISPR-Cas9 is no place close prepared for the center.

Communicative Competence In Language Teaching

Communicative Competence In Language Teaching In this essay, I will first define what Communicative Competence is and what it includes. Secondly, making reference to the European Common Framework of Reference for Languages, I will synthesize why gaining Communicative Competence in a foreign language is so important and why it should be the main goal in an English Classroom. To finish with, I will summarize the best ways of teaching Communicative Competence. Task-based language teaching will be the model I will use as an example of how Communicative competence should be taught and the role instruction should pay in the Classroom. Communicative Competence refers to the ability of understanding, producing, and interpreting the different Communicative events taking into account not only their explicit sense (what it seems to be more immediate for us), but also its implications; that is to say, what the speaker wants to say, what the listener wants to understand, their relationship, the social context, etc. Therefore, Communicative Competence has to do with the social, cultural, and psychological rules that determine the use of a particular language in a particular situation. This term was introduced by Hymes in language teaching in 1972, to complete Chomskys Linguistic Competence term which couldnt explain all the factors which are important for a communicative purpose or in a communicative situation. According to him, Linguistic Competence only deals with the knowledge of language rules and forms, and Communicative Competence includes as well the knowledge that allows someone to communicate correctly and appropriately. Therefore, Communicative Competence is the only means we use to transform language into Communication instead of Linguistic Competence. According to the European Common Framework of Reference for Languages Communicative Competence is divided in: Linguistic Competence: it refers to the ability of producing utterances in an efficient way in all its grammatical levels. It is formed by these competences: lexical, grammatical, semantic, phonologic and orthographic competence. Sociolinguistic Competence: it is the ability of understanding and producing different utterances in different contexts of use where different factors play an important role, such as the relationship between participants, their situation, etc. Aspects to take into account here are social relationships markers, politeness norms, popular wisdom expressions, register differences, dialect and accent differences, etc. Pragmatic Competence: It makes reference to the ability of acting efficiently in a language taking into account grammatical forms and meaning to complete a text (spoken or written) in different communicative events. It includes students mastery of texts, discursive genres, and community speech interpretation. To master this, there are needed rhetorical, cohesive or cohesion devices for conversational organization. Strategic Competence: it has to do with the individuals effective use of language by means of his capacity for using verbal and non-verbal resources to fix errors that can be produced when communicating due to different events that may limit the communicative process. Communicative competence is the first of the eight basic competences that a learner has to have acquired by the end of ESO, but not only this, it is in the same way important to have acquired as well a B1 level of Communicative Competence in a Foreign Language to be admitted in University as the European Common Framework of Reference for Languages dictates. COMMUNICATIVE COMPTENCE IN TEACHING Teachers in ESO should develop in students communicative abilities and strategies in order to reach a B1 level in Communicative Competence by the end of this period, this competence should be acquired in all areas: speaking, reading, listening, and writing. Therefore, this has to be the main goal in the English Classroom. In order to analyze how Communicative Competence is implemented in school, Ive chosen the task-based method, which is a continuation of Communicative Language Teaching according to Rod Ellis. Task-based language teaching is a teaching method based on tasks whose main purpose is to make learners use the foreign language. Tasks are based on authentic events where authentic language is used: visiting a doctor, shopping, calling room service for food, etc. Assessment of errors is not considered as important as in other approaches because accuracy will be gained while practicing the L2 in an incidental way. Besides, Rod Ellis defends that what students really acquire is the implicit knowledge, and this is best facilitated looking at the language as a whole rather than breaking it into pieces in an attempt to teach item by item. Tasks differ from activities in that they focus on meaning rather than on form, in this sense, learners will be creating their own language instead of reproducing the language given to them. They also have an informational or reasoning gap which will make the conversation interesting and therefore it will make them eager to continue it even outside class. Learners also use their resources instead of reproducing the language given to them. The goal of tasks is not to make learners use a correct language, but to engage them in communication. WHAT ROLE PLAYS INSTRUCTION IN A TASK-BASED LEARNING CONTEXT? Instruction plays a different role in Task-Based Teaching: Instruction is seen in an interpretative rather than in a transmission perspective, so its main goal must be to facilitate students processes of learning, which in this case is the acquisition of implicit knowledge. The goal of language instruction is the development of implicit knowledge. If teachers make their students to focus mainly on language form they wont never be able to communicate effectively. The only place where learning occurs is inside learners minds, so teachers cannot just direct that learning. Therefore attention to form will be paid only when communicating, and not all the time, because excessive corrections may stop the conversations rhythm. That doesnt mean that Task-Based theorists dont care about grammar, they defend explicit teaching of rules as well, but only when necessary because the main goal is communication. Instruction has to focus on meaning rather than on form. Rod Ellis thinks that grammar is not needed for basic communication. Basic survival in language relies on vocabulary and formulaic sequences, not on grammar. Students will need grammar as they get involved in increasingly complex tasks, that is to say, the need to use a determinate grammatical form will be created in their minds as complexity increases in tasks. Instruction needs to be motivating, i.e. based on things that learners may find interesting, because its very important to call their attention in order to get them involved in the task. To conclude, I will sum up some characteristics a classroom should have to teach Communicative Competence: Inductive method. Preventing method rather than corrective. Teach sequences of language, not language in isolation. Teach through senses. Promote autonomy. Give your lesson an authentic and ludic character to make it interesting. Set learning goals taking into account the developmental cognitive level of the learner.

Climate Change And The Disaster Environmental Sciences Essay

Climate Change And The Disaster Environmental Sciences Essay Climate change and the disaster of the environment have driven the planet in a crucial state. Although it is irreversible, countries all over the world have entered a route of mitigating this disaster. In this essay we are going to talk about how Hamburg, one of the largest cities in Europe and one of the largest and busiest ports worldwide, have managed to solve in a big percentage, regardless of its big population, issues, among others, like reduction of CO2 emissions and management of waste disposal and recirculation. We are also going to see one environmental issue that hasnt been solved yet and we are going to explore the various impacts of this as well as what Hamburg is planning to do about it in the future.2 The city of Hamburg and the importance of its port The Free and Hanseatic City of Hamburg is a city state and the second largest city in Germany with 1,7 million of inhabitants. It is a cultural and a commercial center for Northern Germany, its metropolitan region consisting of approximately 4 million people. Hamburg municipal area is equal to 755,3 km2 and embraces 14 districts around the City of Hamburg.(HPA,2011) It is the third biggest industrial area In Germany after Ruhr and Berlin, with business related to aircraft and ship building industry, automotive industry and mineral oil processing. However the highest importance is the industry that is related to the harbor and all its activities. The port of Hamburg is the largest port in Germany, the third largest port in Europe and one of the ten largest ports worldwide. Only the port by itself employs around 75,000 people and more than 133,000 jobs are directly or indirectly related to the port due to its high importance as it is one of the most important trading centers in Northern Europe. As for this reason Hamburg sustainability has become very topical as environmental protection has turned into a major factor for business decisions. 3 Environmental issues solved 3.1 Reduction of CO2 emissions Hamburg has gone too far investigating and researching new methods of contributing in the mitigation of climate change. One major issue that has been solved at a considerable percentage is the reduction of CO2 emissions. The efforts are great considering the scale of energy demand, the citys population and the ports traffic. The government itself has gone into an ECO-partnership with the commercial sector, encouraging companies to go beyond statutory requirements regarding CO2 emissions. As for the port, Hamburg has established the Automated container taxis which in fact eliminates the transportation of containers via trucks and instead containers are transported from one terminal to the other, through long distance railway. (New European Economy, 2012) In the city, again Hamburg gives the example, having many cleaner means of transportation for short and long ranges. Not only the worlds biggest fleet of hydrogen-fuelled buses, but also an exclusive bicycle network exists in the city, with additional bike lanes and cycle-hire schemes. (European Union, 2011) Last but not least Hamburg has in many places around the city heating plants which provide district heating. This system produces and provides heating to some districts using, as basic energy consumption renewable energy such as solar energy, wind energy and biomass, combined with fossil fuels. All these have a huge impact on the environment and people because it has a considerable reduction in CO2 emissions, great noise reduction, less need for fossil fuel consumption, so that means, a healthier and greener way of life. 3.2 Waste water management Sustainable waste water management has been a top priority is Hamburg for more than a decade. Mainly the Public Sewage Company HSE but also other organizations have invested a considerable amount of money so that Hamburg will reach a satisfactory percentage of prevention of waste water to go to lakes and waterways. The key issues that were achieved were the storage of waste water in tanks, the treatment of waste water, which actually is the dehydration of the waste water, the separation of ammonia in the waste water (de nitrification) and the energy production from the separated sludge. Especially in the energy production from the sludge, HSE has done a great job, equipping all the treatment plants with a new chain process which exploits energy resulting from the treated sludge. So as a result of this sewage gases are transformed to electric energy, further decreasing CO2 emissions that stated before. (European Union, 2011) C:UsersPanosDocumentsenviromental engineering Sources2012_04_26_Abb Konzept mit Garrest_eng_skaliert.jpg Also there is a concept to come into force from the HWC company in the near future that will be a great innovation. According to that concept every residence will be able to manage, treat, and recycle the waste water disposal and also convert it to energy. All of the above have as a result the creation of a better environment for the flora and fauna in the lakes and waterways, the recycling of the evaporated water which comes in terms of rain and the increase in the oxygen expulsion. 4 Issue that has not been yet solved Since there isnt any city, state or country in the world that has solved all the environmental problems, same goes for Hamburg that has one critical environmental problem that troubles scientists and researchers for long time now and that goes with river Elbe. Due to Hamburgs location and topography there is a need for dredging of accumulating sediments. Since 1990s, it was decided that the deepening of river Elbe was a critical matter since it was found that the sediments were highly contaminated and they needed to be treated before they could go into disposal. 4.1 River Elbe River Elbe is the third largest river in Central Europe after Danube and Rhine and in terms of length it covers a distance of 1091 km (727 km in Germany, 364 km in Czech Republic). Its catchment area goes through Prague, Dresden, Berlin and Hamburg. Especially around the city of Hamburg, where the port of Hamburg is allocated, river Elbe is influenced by the tide. 4.2 Environmental problems on River Elbe As we mentioned before river Elbe is influenced by the tide. This has as a result to have several sediments staying at the bottom of the river, and following that, the level of the seabed of the river is rising through time. In order to sustain the trade of the harbor by having free passage to ships, as well as keeping the harbor fully operational, the depth of river Elbe and thus the depth of navigation needed to be assured. Constant dredging was the answer to the problem to achieve that depth. At the beginning of the idea, the sediments that were dredged from river Elbe were used again for agriculture. However it was found that the dredged sentiments were contaminated with heavy metals (As, Cd, Hg, Zn) and organic contaminants (PCB, Dioxins, PAHs) which had great negative impacts to the environment (Heise, 2005). This pollution was a result of upstream industrial activities in the former GDR (German Democratic Republic) and Czech Republic such as pharmaceutical, chemicals from mini ng, pulp and paper, and leather-processing industries (Netzband et al., 2002). Until 2000 there were some measures that were taken in order to reduce this contamination, such as the treatment of the dredged sediments. This system was aparted from two sections. The first section was the pre-treatment which was the separation of the sediments into sand and contaminated silt fraction, and the main treatment was the dewatering process followed by the environmentally safe disposal of the silt. Both treatments were carried out by one large scale plant named METHA (Netzband, 2002). Since 2000 the sediments have been increasing 3 to 4 million m3 per year (HPA, 2005b). This is of great importance to Hamburg and its environment because from one point the sediments have to be dredged more quickly, due to the current needs of the harbor area and from another point the capacity of METHA has already been exceeded. As it is understandable the continuously dredging of river Elbe destroys its morphological environment, and from at the part of the pollutants we already have a decrease in oxygen, combined with the existence of contaminants we have a progressive destruction of the environment. Especially the summer time the oxygen depletion of river Elbe is great which results in a large number of fish kills. 4.3 Possible solutions Although the dredging of river Elbe is an issue that troubles researchers for over two decades, the impacts are not irreversible. Since the reason for deepening river Elbe is solely financial, it is suggested by the Federal Ministry for the Environment, that a second port should be opened as a deep water port, located at Wilhelmshaven and acting as a hub (HA, 2004a). This is one of the best ideas if it will be financially supported, so that the need of 24 hour navigation on river Elbe, regardless of the tide, will be eliminated as well as the need for dredging. Apart from that, the European WFD (Water Framework Directive) implements new quality standards for chemicals used in agriculture.

When I Was Hit by a Car, and then Realized the Importance of Family :: Siblings Personal Narratives Essays

The Importance of Family It is hard to grow up as a young child without getting a few scraps and bruises. Kids are so active and have to have fun and burn off a little bit of energy. Imaginations are key to fun and to life. As a child one must come up with the most unusual games. Children do not realize at their age how important family is and just how much they give up for their child. It was 4 o’clock pm. The sun had just started to go down. Kids are outside playing after school. My brother Jason was in the 8th grade and I was in 3rd. We had another brother that always played with us too, but I guess that day he was currently busy at the time or just did not like the game Jason and I were playing. My brother, Jason, and I had come up with this game. It involved a soccer ball and a few lines and the only thing that really had made the difference, the garage door. We have a three-car garage and the two-car portion was always open when my brothers and I were in the front playing. We had to use the small door that only one car could fit through. It was the perfect size for the goal. Of course the oldest one would always come up with the rules, it itself was an unspoken rule. Jason had come up with some weird and out of this world rules. I do not remember all of them. One that sticks out the most was whoever was the goalie; they had to get the ball if it went onto the street or out of bounds. The ball we had played with was my favorite ball or toy in the world. It had my two favorite colors on it, purple and green. The ball was a size five, I was little so it had to fit me and how I played. I was pretty good at soccer and was a goalie on my school team; every now and then I would play the field. It was my favorite sport and Jason’s as well. He was very good at the sport and much bigger and stronger than I was, I was only 10. I was doing pretty well he would just hit is harder and harder. The traffic that day was at its usual.

Usher and Red Death Essay -- essays research papers

Run From Death and You’ll End Up Finding It   Ã‚  Ã‚  Ã‚  Ã‚  Edgar Allen Poe is famous for his gothic stories and poetries. In The Fall of the House of Usher, the narrator visits his old childhood friend, Roderick Usher. The Usher family is a noble family that is well known for their incestual behavior, which leads to multiple deformations for their offspring. The only living heirs of the Usher family are the twins, Roderick and Madeline Usher, forever chained to the decrepit house they live in with no chance of escape. In The Masque of the Red Death, a plague is reeking havoc upon the country and Prince Prospero can only do one thing: lock himself and his noble subjects in the abbey to party and not worry about death. In both of the short stories, the characters are stationed inside their house, trying to forget all miseries, but death still occupies the back of their minds. The characters within the short stories are trying to prevent death by running away, but they end up rounding the corner to meet up with Death again.   Ã‚  Ã‚  Ã‚  Ã‚  In The Fall of the House of Usher, the noble Roderick and Madeline Ushers are the remaining children of the family line.

Fast Food vs Organic Essay

Have you ever sat and back and wondered why there are so many obese people in the U. S.? You would think that with all of the buzz about organic foods that we have available, that we would slowly be getting better with our weight as a country. Unfortunately the reality of the situation is organic food are expensive and with the way the economy is today many people are working on a budget and simply cannot afford to splurge on the organic items. So now that we know that lets look at the second half of that equation, Fast Food! Now as much as people criticize the fast food industry it’s convenient and like the name says fast. Now days most people do not want to come home after a long, hard day of work and slave over the stove to cook a hot meal for their family. However what they don’t realize is how much that food is poisoning us. Take McDonalds for example, it has been brought to the public’s attention just what goes on when they are making their food. The food looks like food that you would make in your kitchen, but it is actually manufactured. French fries use to be made by potatoes peeled in the back room and cut into strips. Today they are made in large factories, frozen and processed. Some of the ingredients are very fatty. Even though they have said that they â€Å"were† injecting the chicken nuggets with a pink dye, people are still running to the franchise for their food. I am not judging anyone by any means just stating my observations. Now if you think about it most families probably spend about $100 a week on fast food. Why would so people spend so much money on fast food you ask? Its simple it’s easy, and it’s convenient and inexpensive. Compared to other foods it’s something that working people and ordinary people can go out and enjoy. The design of a fast food restaurant is very well thought out. We form our eating habits as children so they try to nurture clients as youngsters. It’s very important that the fast food companies make sure that their fast food meals for children are healthier. In contrast the benefits of eating organic foods are great and if you can afford them should definitely take advantage of them. The are good for both the earth and the environment. The animals are living stress-free, free-grazing on the land and not being manufactured in deplorable living conditions. Organic farmers use less energy, less water resources, and NO pesticides. Organic farmers’ soil stays rich in content, moisture and nutrients due to careful management of land and using only natural organic matter to grow their crops. When industrialized agriculture arrives in farming communities, many farmers are forced out of business. Each month dozens of new pesticides, show up in local supermarkets and stores. Because they are advertised heavily are purchased and used and thus the destruction of the earth continues slow and steady. Organic farmers, live cleanly. Free of pesticides and toxins.

Yahoo and Alibaba

3. How has the strategic value of Yahoo to Alibaba changed over time since 2005? 2005 was a tough year for Alibaba. Because of the US$100 million investment in China by eBay, Alibaba and its subsidiary – Taobao fell into a severe price war against eBay which hindered the profitability of the group and much more capital was needed for operational and technological improvement in order to win the battle. Under this circumstance, Alibaba formed a partnership with Yahoo! Inc. Yahoo invested US$1 billion in Alibaba and transferred the ownership of Yahoo! China to Alibaba.In return, Yahoo got a 40% stake and 35% voting rights in Alibaba. Beside the cash injection, another reason for the initiation of the partnership was that Alibaba valued much on the importance of search engine for its e-commerce work. At that time, owing Yahoo! China was a competitive advantage of Alibaba against eBay. At that time, Yahoo had much strategic value to Alibaba due to its large capital base and techno logy to help Alibaba safeguard its market share under eBay’s attack. However, the operation of Yahoo! China under Alibaba was unsatisfactory.Since 2005, Yahoo! China has been losing its market share and lagging behind its rivals. Although Alibaba tried to re-orientate it as more business-oriented to grasp the market niche, the effort was in vain. The influence of Yahoo! China in the search engine market in China diminished. Hence, it failed to draw attention of potential customers of Alibaba and was not capable to bring enough benefit to Alibaba leading to a fall in strategic value of Yahoo!. Even for the parent of Yahoo! China – Yahoo! Inc. , the story was more or less the same.The net income of Yahoo dropped 78% in the first quarter of 2009 which resulted in a massive layoff. Due to the low profitability, Yahoo formed a 10-year agreement with Microsoft. Under this contract, Yahoo had to adopt Microsoft’s search technology (Bing) instead of its own technology i n all Yahoo’s website. Similarly, Yahoo agreed to use Google’s search engine in Yahoo! Japan (search ads platform). In other words, it surrendered its own searching technology which Alibaba valued most. Search engine is important to e-commerce companies.As many people use search engine like Google, Yahoo, Bing etc. to get appropriate results of their queries, a smart search engine can allocate much traffic to the e-commerce website by placing their website on the top of result pages so that potential customers can be created. Now that Yahoo lost its own search engine, it may only be able to provide support to Alibaba under Microsoft’s constraints which was unlikely to be what Alibaba wants and thus lowering Yahoo’s strategic value. Unlike the poor performance of Yahoo, the profit of Alibaba surged after the partnership.Apart from being the market leader in China, Alibaba started to expand its business overseas in 2008. For instance, it formed a partnershi p with Informedia India Limited; set up Alibaba Japan, a joint venture with Softbank to foray and launched AliExpress in US etc. All these new strategies had no correlation with its partner – Yahoo! Inc. These revealed that Alibaba was keen on developing new relationships with overseas companies to enter foreign markets. Due to the poor relationship with Yahoo, Alibaba no longer seek cooperation with it and the strategic value of Yahoo further diminished.Because of the poor performance of Yahoo! China, Alibaba started to provide Sogou (a local search engine) in addition to Bing for its customers. This probably made Yahoo’s market share further decrease as customers no longer need to choose Yahoo! China’s Etao as the only access to Alibaba and they can opt for Sogou Shopping instead. Even Alibaba loses Yahoo! China, it still has its new channel to reach its potential customers. It seems that Yahoo has lost its role as an exclusive search engine of Alibaba and los t its strategic value meanwhile.
