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.

Thesis (M.Dev.) --University of Limpopo, 2013 / Agricultural cooperatives have been widely promoted as a vehicle for smallholder agricultural development in South Africa. As a result, agricultural co-operative registrations in South Africa are increasing. However, research suggests that South African co-operatives have generally not been effective, successful and functional. This study has investigated the challenges facing agricultural cooperatives in the Greater Tzaneen Municipality. It is expected that identification of these elements may enable institutions that offer support to cooperatives make better decisions to improve primary agricultural cooperatives support. Understanding of these elements could inform the efforts for members of cooperatives to achieve their set objectives and thus improve agriculture cooperative, employability, functionality and profitability. A case study of the Nkomamonta Agricultural Primary Cooperative in the Greater Tzaneen Municipalities is used. It is composed of fifteen agricultural cooperative which were purposively selected for the study because they were nearby, they are a pilot agricultural cooperative in the municipality and which are also not functioning as expected. The sample also included the purposively selected members, customers of these agricultural cooperative, workers, Greater Tzaneen Municipality, Local SEDA and LIBSA to explore the differences and provide insight to the knowledge, opinions and challenges that are facing agricultural cooperatives. One-on-one interviews were carried out with co-operative members as well as focus group discussions with customers, members of the cooperatives, workers, the Municipal officials, SEDA and LIBSA. A framework for analysing the challenges agricultural cooperatives with reference to the Nkomamonta cooperative case study was developed using literature of objectives of agricultural cooperatives, challenges which were identified by other researchers and success factors of smallholder agriculture. According to this study, farmers’ activities are hampered by a number of constraints. Production capability of the fifteen primary cooperatives is hampered by resource constraints such as lack of access to land (in one cooperative), machinery and equipment, finances and information relevant to production. Marketing, transportation, poor infrastructure and the elderly age of some cooperative members and issues related to free-rider syndrome were part of the problems that were identified. Low capability of some of the fifteen cooperatives to mobilise resources, use the limited resources available and low capability to manage institutional arrangements rendered the cooperatives ineffective in achieving their set objectives. The study recommends strategies for ensuring that the challenges facing agricultural cooperatives are minimised to better their services in the community. These include strategies for addressing internal and external issues affecting the cooperatives. Direct intervention from government is recommended to improve production through revising land allocation systems which made Kulani Agricultural Cooperative not to have land for growing crops. Jerry Jeff and Nwa Rex went out of action for eight months due to renovation of neighbourhood inorganic farms by the Department of Agriculture. Another strategy would entail improving extension services and follow up and strict monitoring of effective use of government resources provided to farmers. Responding and action taking when disaster has struck the agricultural cooperative by Government is also a plausible strategy. Access and training to relevant technologies to improve the processing and packaging capabilities of cooperatives should improve. Marketing and management activities should be supported through provision of improved infrastructure and relevant training. Farmers themselves should consider assisting one another especially regarding land issues as it was discovered that 67 hectares lay unutilised while the farmer next door needed land. Farmers should also engage in value added activities, and improve marketing programs and cost-effective distribution mechanisms.
