This study was carried out to assess the effect of storage of cassava roots in polyethylene sacks for periods of 2, 4, 6 and 8 weeks on the sensory characteristics of cassava fufu, a popular Ghanaian dish. Freshly harvested cassava roots were dipped in tap water and packed into polyethylene sacks in 2‐kg batches and stored at room temperature (25°C ± 1°C). Samples of fresh cassava fufu were evaluated and then at two weekly intervals for a period of 8 weeks. Attributes evaluated were colour, smell, elasticity, smoothness and taste. A structured six‐point ranking scale ranging from 6 (excellent) to 1 (very poor) was used for the evaluation. The data were analysed using analysis of variance, and the least significance difference test at P < 0.05 was used to determine differences between means. The results showed that storage of cassava roots for up to 8 weeks did not significantly affect the colour, smell, elasticity and taste of cassava fufu. However, smoothness of fufu prepared with cassava stored for 6 and 8 weeks was significantly different from the samples of the fresh cassava, and those stored for 2 and 4 weeks. It was concluded that cassava roots stored for periods up to 8 weeks in polyethylene sacks produced fufu of similar characteristics as fresh cassava fufu. This method is therefore recommended for use by homemakers, food service operators, cassava retailers and processors to save them time, energy and money used for the frequent trips for purchases. The method would also reduce post‐harvest losses to a large extent. 相似文献

We study bilateral conflicts that affect the welfare of third parties, the stakeholders. The conflict takes the form of a war of attrition and intervention is modeled as the possibility that the stakeholder “aids” the agreement with transfers to the contenders. We characterize the optimal policy when the stakeholder limits its intervention to a unilateral commitment to compensate the contenders if the conflict is resolved, and show that if contenders must be treated equally after agreement, then the optimal policy cannot eliminate the delay in resolving the conflict, and intervention is only advisable when the stakes are high enough. Economic diplomacy is modeled as a three‐player game where the stakeholder is actively involved in the negotiation where transfers are discussed simultaneously with a settlement for the conflict. We prove that, provided that none of the parties involved is too impatient, diplomacy benefits the third party in all conflicts. 相似文献

ABSTRACTCambodia is known as a hotspot for land grabbing in Southeast Asia. Land dispossession due to elite capture, natural resources exploitation, and agribusiness development has catalyzed international attention following outbreaks of violence, mass protests, and retaliations. Agrarian economies, as well as social and gender relations and thus power dynamics at different levels, are being transformed and reshaped, facilitated by policies that promote capital penetration in rural areas and individualization of land access. Focusing on cases of rural dispossession and political resistance in Ratanakiri and Kampong Speu provinces, and drawing on reports, government documents, focus group discussions, and interviews, this study analyzes the gendered implications of land grabbing in contemporary Cambodia and argues that gender shapes and informs women’s responses and politics, as well as the spaces in which these are played out. 相似文献

The aim of this study was to analyse the determinants of reverse takeovers, examining the influence of target firm shareholders’ type in the agreement. We examine reverse takeovers implemented in the Alternative Investment Market between 1999 and 2012, paying special attention to the differences between family and non-family target firms, as well as the impact of the financial crisis.
We propose that family firms have a lower probability of accepting a reverse takeover (‘shell’ firm), to avoid both diluting the ownership structure (loss of control) and new shareholders entering their firm. Our main findings show that the higher the percentage of ownership held by family holders, the lower the probability of their being the target firm in a reverse takeover. This effect is maintained during the crisis period, in accordance with the expectation that family firms will have fewer financial constraints. 相似文献

Household food waste is considered to be the largest share of food waste along the food supply chain. Given that its recoverability is also more challenging compared to food waste in other stages of the chain, most studies on household food waste adopt a pre‐emptive approach by aiming to identify and address consumer beliefs, attitudes and actions that are linked to food waste. In scientific literature, household food waste has often been studied in relation to the habit of purchasing discounted food products (DFP). However, findings have been contradictory. Specifically, while some authors found that deal‐prone consumers are usually of lower income and therefore display a wiser and more attentive attitude towards grocery shopping, other authors reported that the purchase of discounted products was usually linked to compulsive shopping, hence resulting in higher food waste quantities at home. Due to these discrepant findings, a definitive answer on the impact of DFP on household food waste does not currently exist in the literature. This paper analyses the correlation between the purchase of DFP and weekly household food waste quantities. To do so, we examine (a) the results of a food waste diary experiment carried out on a representative sample of 385 households in Italy in February 2017, and (b) the results of a 23‐items Computer Assisted Web Interview survey administered to the same householders, in which shopping habits were investigated. Results revealed no evidence of either a positive or negative relationship between the purchase of DFP and household food waste quantities. Frequency of grocery shopping was the only variable found to have a significant impact on household food waste quantities. 相似文献

We present a continuous-time model of multiperson bargaining with incomplete information, where only two agreements are possible. We show that under mild informational assumptions, players behave as if they were representing the other players who prefer the same alternative, individually playing a war-of-attrition against a conglomerate player of the opposite side. We also provide a characterization of the perfect Bayesian equilibria in undominated strategies of the game, which yields a unique outcome in most cases.Journal of Economic LiteratureClassification Numbers: C72, C78, D72, D74. 相似文献

The aim of this article is to investigate the influence of advertising spending and mood on consumers' perceived quality, considering scenarios with slight and severe information asymmetry as regards a product's attributes. An experimental study conducted with 385 subjects demonstrated that mood moderates the impact of advertising spending on consumers' perceived quality, specifically when these expenses are at and above the market average. Moreover, the impact of mood on perceived quality was moderated by the level of product information. These results have several theoretical and managerial implications, and may help companies to invest their advertising resources more efficiently. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

Police performance is not easily measurable and the organization and circumstances of police work vary among European countries. Further, police work is surrounded by multiple pressures to make it both economical and effective. Consequently, there are multiple institutional logics in decision-making which may affect the selection and the use of police key performance indicators (KPIs). The KPI selection and use processes reflect the institutional logics, though KPI use may also sometimes influence the institutional logics of police work. In this study, we analyze the KPIs and institutional logics in police work in Finland and Spain. A comparative case research approach is used in order to highlight the differences in institutional logic emphases and in circumstances. Data from semi-structured interviews, internet reports, project work, and discussions are used. Both similarities and differences in the KPIs and in the institutional logic emphasis are found between the Finnish and Spanish police. Understanding the partly general and partly locally constructed nature of institutional logics may facilitate the development of police work performance measurement. We also suggest ways of coping with multiple institutional logics. For example, risk analyses and selecting KPIs against the current institutional logic may facilitate organizational developments. 相似文献

Renewable resource market obeying difference equations: Stable points,stable cycles,and Chaos (1991)
Clara Costa Duarte 《Environmental and Resource Economics》1994,4(4):353-381
In this paper, the basic principles of the Chaos Theory are applied to dynamic systems involving renewable resource and harvest. The results of simulations are presented regarding harvested resource stock time path. It is shown that stationary steady-state is only one of many different possible outcomes of bioeconomic equilibrium. The varying impacts that different management policies have on an unstable dynamic system are also studied. It is shown that in unstable resource systems, the effects of some policy measures will be very different from the ones obtained through traditional resource analysis. It also shows that policies which induce a stabilizing effect in stock time series will generally provide greater welfare gains. The results are illustrated by two market examples. 相似文献
