Cooperation have in previous research been seen as a negative impact on competition and  vice versa. This thesis is building on a concept called coopetition in which cooperation and  competition is studied simultaneously. Coopetition have been studied in terms of the level of  cooperation and competition. However, we found a possible link between coopetition and  complexity in previous literature. Thus, the purpose of this study is to explore whether  complexity can develop an understanding for what organizations within a company group  cooperate and compete about as well what they want to cooperate and compete about.     The four main cornerstones in the theoretical frame of reference is cooperation, competition,  coopetition and complexity. We begin by defining these concepts, describing previous  research and discuss various factors of the concepts. Finally, we further develop the possible  link between coopetition and complexity.    For reaching our purpose we study a company group in the travel industry. We are  conducting unstructured interviews with people at leading positions in the company group.  Our analysis is done by thematic network analysis in six steps.    The empirical data is coded, basic themes are found and a condensed version of the  interviews is presented together with a short presentation about the company group.     In the analysis we present two global themes, cooperation and competition. These are both  derived from the basic themes and organizing themes. The factors of complexity are the  organizing themes.    Our conclusion is that complexity can categorize wanted and actual cooperation in the  company group in the sense that complexity has to be lowered for cooperation to exist.  Regarding competition, we did not draw any conclusion to our purpose due to lack of data.  However, we find that competition is mainly seen as negative in the coopetitive situation  studied.     The implications of this thesis is that complexity can further refine the concept of coopetition  but the causality have to be further tested. In a managerial perspective, leaders should focus  on decreasing the factors of complexity if cooperation is wanted. We also suggest that it is  important to understand if people in organizations are positive towards cooperation and  negative to competition or the other way around.

I investigated dietary differences, overlap and shifts for two atherinid fish species inhabiting the highly modified Tennessee-Tombigbee Waterway (TTW) in Mississippi, U.S.A. The Mississippi silverside (Menidia audens) is now common throughout the waterway and apparently invaded from the Tennessee River after man-made connection with the Tombigbee River in the mid 1980s. A subsequent decline in the distribution and abundance of the native brook silverside (Labidesthes sicculus) led to speculation that dietary competition might be involved. I used extant data to test the null hypotheses that diets are not different between the two silverside species in TTW, that dietary overlap between them is random and that no dietary niche shift occurs for either species in the presence or absence of its putative competitor. I accomplished this by quantifying the diet of both species from sympatric and allopatric collections, then using multivariate statistics and null models to test for significant dietary differences, overlap, and niche shifts. The analysis indicated that diets differed significantly between the two species. However, dietary overlap at sites of co-occurrence was greater than expected under conditions of incipient competitive exclusion; and, dietary niche shifts were not found when the diet of either species in allopatric collections was compared to its diet in sympatric collections. Thus, there was no evidence for direct involvement of dietary competition in the population trends of silversides in the Tennessee-Tombigbee Waterway. Yet, it appears that M. audens is replacing L. sicculus in dominant habitats of TTW, just as has happened in other, similar systems. Simulations with STELLA� were used to estimate the degree of inter-specific competition that might account for observed rates of replacement. Results implied a 10 % ecological advantage of M. audens over L. sicculus.

Among Taiwan small and medium enterprise, there exists a debate about should they create own brand or should they still do under OEM way. Even in IEMAB class in Managing College, National Sun Yat Sen University, we have received many comments from professors of two parties, no mention about the practical way, Taiwan small and medium enterprises they are thinking now. This thesis is using Michael Porter¡¦s ¡§Diamond Theory¡¨, ¡§Competition Advantage¡¨ to analysis Winex CO., Ltd. how they competing in world market and how they entering each country, especially those major market countries, such as Netherlands, Indonesia, China. It may be a long way to create own brand name, especially need to overcome the financial crisis during it, but it is still the best way for any enterprise in Taiwan who want to look for a free future and great dream. The Small and Medium Enterprise Adminostrion,MOEA, Taiwan, in their ¡§Small and medium Enterprise Year¡¦s Paper¡¨ has a lots of analyses and suggestions to Taiwan¡¦s small and medium enterprise. Here is taking this case company to make a further comparison so it might make this thesis to be more practical and useful.

The tips of the fourth and fifth pairs of pereiopods of the Dorippe quadridens are hook-liked that enable them to carry some objects. Many researches have studied the carrying behavior of this crab, but very few on its behavior related to competition for resource (i.e., the objects such as shells). This study was designed (1), to investigate the effects of body size, autotomy (loss of these pereiopods), and order in occupation of shell on the final passion of the shell (i.e., the resource), and (2) selectivity of shell. Dorippe quadridens often chose the shells larger than its pereiopod width. Weights of the selected shell were not related to the body weight of the crabs; they preferred larger but lighter shells. Probability of finding a shell did not correlated either with body size or the condition of the pereiopods. Under an asymmetric contest for shell, a shell owner stood a higher chance of holding on to the shell against an invader which tried to rob the shell. This situation did not replay in a symmetric contest. A small shell owner and a smaller invader for shell behaved differently against their larger competitor as contrast to a symmetric contest for shell. Duration of fight for shell was related to the size differences of the contestants. Under the symmetric-contest condition, durations of fight in pairs of variable sizes remained relatively constant that this parameter was not affected by the sizes of the contesting pairs. It appeared that the D. quadridens made decision on the fighting strategy by assessing the conditions of the opponent and themselves; they would fight against or escape from the opponents under different conditions. The behavioral performances observed in this crab species conform to the definition of interference competition.

In recent years, economical fast development, the corporate faces the globalization expansion, and in under pursue biggest profit premise, every managers tries to utilization each innovation transforms the strategy makes every effort the promotion competitive advantage in the global market. To achieve the enterprise continues forever goal of the development. However, one after another financial scandal erupted in the American and Asia, it impacts the corporate to think about relationship between the corporate competition and the corporate social responsibility. In the past, to pursues the maximum profit is traditional ideas for the practice of market. Since the corporate scandal erupted, corporate starts to consider how to evaluate the business performance. Moreover, the regards the topics on environmental protection and staff rights and interests attack corporate image seriously. Definitely, more and more evidence to show the ethics orientation obtain the positive benefit. More and more corporate expresses the social responsibility is helpful for the company. They understand the company can gain the long-term competitive advantage with the fusion for the company image and the corporate social responsibility. They understand the respect from social is not only create the value for the shareholder, but also unfold the intense support environmental protection and the social responsibility. This study is according to the humanity responsibility, ethics responsibility, the legal liability, in Carroll, Archie B. (1991) The Pyramid of Social Responsibility ( in the Chapter II), and using the case study. It is positive relationship when company provides the result: the company competition and to implement the social responsibility.

Indigenous natural enemies occur within field grown crops at varying densities dependent upon a variety of other biotic and abiotic parameters. This natural control often does not provide adequate suppression, which results in the application of other remedial pest management solutions including augmentative biological control. When releasing mass-reared natural enemies into a backdrop of indigenous natural enemy populations, competitive interactions are likely to occur. To assess the influence of these interspecific interactions on the outcome of such biological control practices, studies were conducted both in a laboratory and in a simulated, field grown, cut chrysanthemum (Asteraceae: Dendranthema grandiflorum) production system. Competitive interactions of two commercially available parasitoids were studied both in terms of parasitoid-host population dynamics and the impact of interspecific interactions on crop quality at harvest in this type of system. The parasitoids Diglyphus isaea and Dacnusa sibirica attacking the leafminer Liriomyza langei were used as the model insect system. Both parasitoids are cosmopolitan and are known to occur in many ornamental production areas. Conclusions drawn from laboratory experiments were that D. sibirica produces more offspring that D. isaea over approximately the same number of days. Treatment comparisons in the field included single species releases with complimentary releases of both species either simultaneously or with two-week time lags, as well as a no release control to measure the background effects of natural mortality. Conclusions drawn from results of population-level studies replicated within and among years were that levels of interspecific competition among parasitoid species were undetectable at leafminer densities typical of field-grown ornamental crops; thus, the efficacy of one species released into a backdrop of potentially competing parasitoids did not negatively affect the outcome of the augmentative biological control. The two species were able to coexist inside field cages for the duration of the crop. Most of the release treatments suppressed host densities lower than the control cages where no parasitoids were released, and there were no treatment effects on host suppression. Even though parasitoid release combination did affect the amount of damage visible at harvest, there was no influence on the number of flowers produced (yield).

ABSTRACT Under the worldwide economic depression, Taiwan electric companies are facing the global competition and the cheap labor force pressure from mainland China. It has been 10 years since W- Company was founded. Due to the impact of active matrix industry confronts the market recession worldwide. ¡§¢å¡¨company is a small company of LCD module industry in Taiwan. The company was founded by owner with the personal technology. The company has been suffering many times of Economic prosperity circulation and product life cycle variance for thirteen years. The ¡§¢å¡¨company could overcome the difficult and made company getting bigger because it based on the owner ,Mr. Hon, correctly judgments of the market situations and execute the efficient strategy. Currently the ¡§¢å¡¨company suffer a different condition. In the serious Market competitions, the ¡§¢å¡¨company lost the biggest order from his customs. This frustration made Mr. Hon very distress, but that could not make Mr. Hon admitting defeat. He was searching efficient strategy to make ¡§¢å¡¨company stable growth and reaching the target of conduct for ever. What is the efficient strategy for ¡§¢å¡¨company to success once more? This text used the case of studies pattern to describe the development of ¡§¢å¡¨company. The written pattern refers the case studying of HARVARD BUSINESS SCHOOL. I hope the text could become the case of the strategy Realm case study¡¦s teaching. Keywords: competition life cycle strategy
