区域物流需求指标体系初探

区域物流需求的分析是区域物流规划制定的决定性影响因素,由于当前的理论和实践多偏重于具体预测方法的研究与应用．而对于需求指标体系的建立尚无系统描述为保证需求指标的科学性和完整性,应从规模指标、速度指标、弹性指标、强度指标、能力指标采其同表征物流需求;为了保证需求指标的可操作性和易操作性,选取物流设施用地规模及物流设施投资额作为与需求指标相对应的物流要素供给控制指标。     

TEN YEARS OF GENERAL OLIGOPOLISTIC EQUILIBRIUM: A SURVEY

In this paper, I survey the recent and rapidly increasing theoretical literature using the brand‐new approach in embedding oligopolistic competition in general equilibrium, as designed by J. Peter Neary. First, I introduce the reader to Neary's approach, by describing the main ingredients. Then, I present a comprehensive set of studies that, over the last decade, apply this approach in different contexts, most of which are in open economy, and I examine the relevant outcomes. Although the theoretical literature has generously advanced, there is a lack of research on the empirical side, which would be an important area for future research besides theoretical extensions, some of which I highlight in the conclusions.     

城市区域交通状态判别方法研究

随着新一代智能化交通控制系统的出现,城市区域交通状态判别方法的研究显得尤为重要。本文在已知各个子区交通状态的基础上,用层次分析法确定出各个子区在区域中所占的权重,然后用加权平均法得出区域的交通状态。最后利用VISSIM软件模拟验证了本文算法的合理性。     

Evaluating expectations of <Emphasis Type="Italic">L</Emphasis>-statistics by the Steffensen inequality

By combining the Moriguti and Steffensen inequalities, we obtain sharp upper bounds for the expectations of arbitrary linear combinations of order statistics from iid samples. The bounds are expressed in terms of expectations of the left truncated parent distribution and constants that depend only on the coefficients of the linear combination. We also present analogous results for dependent id samples. The bounds are especially useful for L-estimates of the scale parameter of the distribution.

Challenging The Spirit Level: Is There Really a Relationship between Inequality and Obesity?

This paper examines the proposition, set out in The Spirit Level, that inequality is associated with high levels of obesity. It reviews existing literature and uses British Household Panel Survey data to study how district‐level and regional‐level income inequality is related to obesity in the UK. This is likely to be the first study of its type that uses individual‐level data that is representative of the UK population. We find little evidence to support policies that reduce income inequality with the aim of reducing obesity levels in the UK.     

Regional variations in entrepreneurial cognitions: Start-up intentions of university students in Spain

Empirical research has recently paid considerable attention to the role of environmental factors in explaining regional variations in entrepreneurial activity. However, cognitive models have not usually included these factors in their analyses. Therefore, the main objective of this study is to identify some of the environmental cognitive elements that may explain regional differences in start-up intentions. Thus, an entrepreneurial intention model is developed, theoretically based on the planned behaviour approach, institutional economic theory and social capital theory. The empirical analysis is carried out using structural equation techniques over a sample of 549 final year university students from two Spanish regions (Catalonia and Andalusia). Results confirm that valuation of entrepreneurship in each region helps explain regional differences in entrepreneurial intentions. As expected, social valuation of the entrepreneur was higher in the more developed region (Catalonia), positively affecting perceived subjective norms and behavioural control. In Andalusia, the influence of perceived valuation of the entrepreneur in the closer environment was more important, affecting attitude towards the behaviour and subjective norms. These results explain some of the differences in the pool of potential entrepreneurs in each region. They also justify the need by public-policy decision-makers to promote more positive entrepreneurial values in relatively backward regions.
