企业失败的原因是领导者不合适

1997～2007年，过去的这十年时间对于许多企业领导来说都是一段异常艰难的时光。家得宝、西门子、波音、壳牌、宝洁、施乐、肯马特、可口可乐、AT＆T、花旗、美林等等，这一长串光辉的名字都在过去的十年里，由于领导者的失误而遭受了前所未有的危机：     

Is What’s Good for the Business,Good for the Family: A Financial Assessment

Small business prosperity doesn’t necessarily translate into family prosperity. This study utilizes the first and second waves of the National Family Business Survey to explore the influence of changes in key business financial measures on objective and subjective measures of family success. Increases in the available cash in the business from higher gross sales or net profits brings more cash into the household, while increases in the market value of the business increases the amount of money spent on other household assets. A more subjective assessment suggests that positive changes in the business financial measures create a more positive perception of the business’ success; however, these positive changes have no influence on a more positive perception of the family’s success.     

On the analysis of long-term experiments

Summary.  Long-term experiments are commonly used tools in agronomy, soil science and other disciplines for comparing the effects of different treatment regimes over an extended length of time. Periodic measurements, typically annual, are taken on experimental units and are often analysed by using customary tools and models for repeated measures. These models contain nothing that accounts for the random environmental variations that typically affect all experimental units simultaneously and can alter treatment effects. This added variability can dominate that from all other sources and can adversely influence the results of a statistical analysis and interfere with its interpretation. The effect that this has on the standard repeated measures analysis is quantified by using an alternative model that allows for random variations over time. This model, however, is not useful for analysis because the random effects are confounded with fixed effects that are already in the repeated measures model. Possible solutions are reviewed and recommendations are made for improving statistical analysis and interpretation in the presence of these extra random variations.     

Business and industrial statistics: the early years

Before his death in July 2002, George Barnard had started writing a sketch of the history of business and industrial statistics in the first 50 years of the twentieth century. The piece was never finished, but it is nonetheless a valuable memoir of the early development of the discipline, from someone who knew those involved.     

Understanding the concept of food sovereignty using the Ghana School Feeding Programme (GSFP)

This article deepens the understanding of the emerging food sovereignty concept using a case study of a home-grown school feeding programme that promotes local food demand – supply linkages. A school feeding programme in four selected districts in Ghana is analysed with respect to community involvement in programme implementation and management as well as its socio-economic impacts. A combination of quantitative and qualitative methodological approaches was used in data collection and analysis. Results showed a significant improvement in household food access and months of adequate household food provisioning, which were used as measurement proxies for food sovereignty, as a result of access to local market created by the Ghana School Feeding Programme. However, the study recommends more empirical evidence from research to support the claim that using locally produced food for school feeding actually reduces poverty and malnutrition in rural farming communities.     

微妙地使用权力

要想实现一个人的目标，至关重要的一点就是要学会有效地利用自己手中的权力。在完成了与苏联的裁减核武器条约谈判，并主持过Bechtel公司的工作之后，乔治·舒尔茨开始真正彻底地理解了权力的内涵。他的建议是：“不要害怕权力，但一定要学会对它负责。”     

Pure hyperbolic discount curves predict “eyes open” self-control

The models of internal self-control that have recently been proposed by behavioral economists do not depict motivational interaction that occurs while temptation is present. Those models that include willpower at all either envision a faculty with a motivation (??strength??) different from the motives that are weighed in the marketplace of choice, or rely on incompatible goals among diverse brain centers. Both assumptions are questionable, but these models?? biggest problem is that they do not let resolutions withstand re-examination while being challenged by impulsive alternatives. The economists?? models all attempt to make a single equilibrium preference predictable from a person??s prior incentives. This was the original purpose of these models?? hyperboloid (???¨C????) delay discount functions, which have been widely justified by the assumption that a person??s intertemporal inconsistency (impulsiveness) can be accounted for by the arousal of appetite for visceral rewards. Although arousal is clearly a factor in some cases of intertemporal inconsistency, it cannot be blamed for others, and furthermore does not necessarily imply hyperboloid discounting. The inadequacy of ?¨C?? functions is particularly evident in models of internal self-control. I have reviewed several of these models, and have argued for a return to pure hyperbolic discount function as originally proposed, the relatively high tails of which can motivate a recursive process of self-prediction and thereby the formation of self-enforcing intertemporal contracts. Such a process does not require a separately motivated faculty of will, or incompatible goals among brain centers; but it also does not permit the prediction of unique preferences from prior incentives.
