根深蒂固的自由主义和压迫性的社群关系--道德教育主体面临的一个两难困境

现代西方道德政治理论中,自由主义主体这个概念作为道德经验、阐释、批评的中心一直非常繁荣。然而,本文认为某种道德上意义重大的关系——那种通过分等级的权力结构由互相联系的社会群体构成的关系——构成的一种不同的主体意识需要更多的理论和实践上的注意。和自由主义的四种核心特征相对应,本文从个体是怎样成为一些特殊的社会群体的成员来论述一种主体意识视角。文章认为,除非道德教育能认识到这种主体意识,否则道德教育本身就冒着为压迫形式(如种族歧视)作贡献而不是同它搏斗的风险。     

Incorporating inventories into supply and demand analysis

Conclusion In the microeconomic portions of principles and intermediate macroeconomics, supply and demand analysis is presented as the truth. However, the simple Keynesian macroeconomic model virtually ignores market clearing, while the standard microeconomic model of supply and demand assumes perfect market clearing. Since hidden assumptions are a major source of confusion and misunderstanding between economists and the general public, students should be exposed to stock-flow analysis at the intermediate level as a separate or integrated chapter on supply and demand.     

A welfare analysis of the site value taxation model

This study is a short-run version of Brueckner's (long-run) analysis of graded tax systems. Brueckner assumes a long-run market equilibrium that allows for changes in the market value of the land with a zero profit condition. It is our contention that it is more realistic to solve for the short-run conditions with fixed value of land. Under these conditions, we find that if land is relatively inexpensive, the graded tax system leads to superiority in terms ofk (capital improvement per unit of land),Q (initial housing output), andCS (Consumers' Surplus). With steeper inverse demand curves and greater marginal product and initial housing output, the land tax has a more negative impact on profit with graded tax systems.     

Pleasure and the Control of Food Intake: An Embodied Cognition Approach to Consumer Self‐Regulation

Consumers try to avoid temptation when exposed to appetizing foods by diverting their attention away from their senses (e.g., sight, smell, mouthfeel) and bodily states (e.g., state of arousal, salivation) in order to focus on their longer term goals (e.g., eating healthily, achieving an ideal body weight). However, when not including sensations in their decision‐making processes, consumers risk depleting their self‐regulatory resources, potentially leading to unhealthy food choices. Conversely, based on the concept of “embodied self‐regulation,” the suggestion is made that considering bodily states may help consumers regulate their food choices more effectively. A new model is proposed that facilitates understanding observed consumer behavior and the success or failure of self‐control in food intake. It is argued that bodily states and sensory information should be considered when modeling consumer behavior and developing health‐related advocacy and communication campaigns. The model proposed here leads to new perspectives on consumer consumption behavior and health policy research and strategies.     

Investment effects of departures from governmental present-value budget balance

The paper investigates whether departures from government borrowing constraints affect the relationship between fiscal-policy innovations and changes in the investment level. ‘Break points’, or apparent departures from present-value budget balance, are then identified. Next, the investment-deficit relationship is examined prior to and following identified break points in an effort to detect potential changes in behaviour. The investment-deficit relationship is quantified by examining posterior coverage bounds of impulse response functions. Britain appears to undergo such a break around 1973. Data from this country suggest that significantly more crowding out occurred following the identified breaks: in contrast, data from other comparison countries that do not appear to have experienced breaks indicate stable investment-deficit relationships.     

Use of the net present value criterion in a random job shop where early shipments are forbidden

Both practitioners and researchers in the field of Operations Management have suggested that shop scheduling should be an integral component in both the strategic and tactical plans for an organization's assets. This paper examines the use of an accepted measure of return on assets, net present value (NPV), in a simulated shop scheduling environment where early shipment of jobs before their due dates is forbidden. In addition, early shipment of raw materials to the shop is also forbidden. This shop environment is consistent with the prevalent practice in industry of accepting orders only on a just-in-time basis to reduce purchased parts inventories. The NPV measure provides a means of balancing a variety of performance criteria that have been treated as separate objectives previously, including work-in-process inventory, finished goods inventory, mean flow time and mean tardiness, while also providing a means of measuring monetarily the value of various shop scheduling approaches.The NPV performance of priority scheduling rules and order release policies is measured in this research through the simulation of a random job shop under a variety of environmental conditions. It is found in a comparison of priority rules that use time-based information with those that use job value information that the Critical Ratio rule provides higher average performance than the three other rules used in the study. However, in some situations that are consistent with JIT practice, value-based priority rules also perform well. The use of a mechanism for delaying the release of jobs to each work center in the shop provided higher average NPV when shop utilization was set at a low level of 80%, while immediate release of work upon its arrival to the shop provided superior performance at a higher shop utilization level of 94%. While JIT materials delivery and costing yields higher NPV, it did not alter the relative ranking of priority rule/release policy combinations. In addition, it was found that environmental factors, including average job length, average number of tasks per job and level of tardiness penalty, resulted in greater variations in NPV performance than the institution of a JIT raw materials delivery policy.
