To examine the effects of cooperative learning on EFL students in Taiwan, a 12-week quasi-experimental pretest-posttest comparison group research study was designed. Two college classes (42 students each) in Taiwan participated in the study, one receiving grammar instruction through cooperative learning and the other through whole-class teaching. Three specific research questions guided the study. The first looked at effects of cooperative learning on motivation, the second on out-of-class strategy use, and the third on grammar achievement. Additional exploratory questions examined these results across subgroups within each class as well as the relationships between the dependent variables. Data were collected via learners' pretest and posttest scores on the dependent variables. The data were analyzed with MANCOVAs, one- and two-way ANCOVAs, simple effects, and Pearson correlations. Cooperative learning was found to have large positive effects on motivation and strategy use, and medium-to-large positive effects on grammar achievement. Overall, the findings indicated a consistent pattern in favor of cooperative learning over whole-class instruction in teaching the Taiwanese learners English grammar. The results of the exploratory questions indicated that cooperative learning facilitated motivation and strategy use of learners across all subgroups, but more so with those performing at higher and lower levels. Grammar achievement of learners at higher and lower levels was affected positively. Additional analyses also indicated cooperative learning positively affected learning at higher cognitive levels. Implications for future research and for curriculum and instruction are addressed.

We consider two firms which pool some of their inventory. The pool is created by the firms' contributions, and a firm's entitlement for an allocation from the pool (if needed) is a function of its contribution. Transshipment from the pool is costly, but the firms can benefit from reduced risk through inventory sharing using the pool. We analyze the resulting non-cooperative game. We prove existence of a Nash equilibrium and compare it to a model with centralized control. An appropriate compensation cost for using the other firms contribution to the pool can induce the retailers to achieve centralized solutions. We also compare the optimal partial pooling strategy to the special cases of no pooling and complete pooling and discuss situations where it is likely that one of the special cases will be optimal. Numerical results confirm that in the prevalent practice of partial pooling the retailers can achieve higher expected profits than under no pooling or complete pooling and that there is a significant difference between a setting with independent players and a model of central control.

Although group-living is widespread in animals, the degree of social complexity varies markedly within and among taxa. One important precondition for the evolution of higher forms of social complexity is increasing group size. However, this imposes a challenge: finding sufficient food for growing numbers of individuals. One hypothesis is that the (in)ability to avoid resource competition as group size increases, could partly explain variation in social complexity among vertebrates. Increasingly, evidence suggests that resource competition can be reduced via three forms of individual specialisation. These are foraging niche specialisation, specialisation to a role under division of labour (DoL), and as a mediator of these two, personality variation. Yet few studies have directly investigated the role of these specialisations in mediating the costs of increasing group size in social vertebrates. In this thesis, I first review the evidence to date that specialising to a foraging niche, and/or to a task under DoL, is (1) mediated via personality variation and (2) can be a means of reducing competition, generated by increasing group size, in social species (Chapter 2). Then, using the cooperative breeding chestnut-crowned babbler (Pomatostomus ruficeps) as my model system, I empirically test some of the hypotheses posed in this review, regarding foraging niche specialisation and associations with personality variation. In Chapter 3, I show that babblers do show personality variation in traits likely to facilitate niche segregation, and in Chapter 4 that variation among individuals within groups is sufficient to lead to intragroup niche specialisation. However, I find that the level of variation within groups is not associated with group size. Then in Chapter 5, I show that in a direct measure of foraging niche, there is only limited evidence for intragroup specialisation, and again that any specialisation is not associated with larger group sizes. I therefore find no evidence that niche specialisation is a means through which babblers can overcome the costs of increasing group size. I discuss the implications of these results for the rise of social complexity in this system, and social vertebrates generally.

Thesis is focused on "Strategic Analysis" has been applied on cooperative DELANA. The aim of this work is use of appropriately chosen methods of strategic analysis to describe and analyze the current situation of the cooperative and to determine its market position. After the strategic analysis there will be an assessment and suggestion of changes that would improve the economic situation of the whole company.

In this case study, researchers investigated the instructional methods used to train private pilot students at Utah Valley University. Traditional one-on-one individualized learning methods were replaced with cooperative learning methods. Descriptive statistics were used to determine the effectiveness and efficiency of the cooperative learning methods used. Reduced training time, less repeated lessons and a reduced number of flight hours showed that cooperative learning methods were more efficient and a more effective way to train private pilot students at Utah Valley University.
