The quasi-score function, as defined by Wedderburn (1974) and McCullagh (1983) and so on, is a linear function of observations.
The generalized quasi-score function introduced in this paper is a linear function of some unbiased basis functions, where
the unbiased basis functions may be some linear functions of the observations or not, and can be easily constructed by the
meaning of the parameters such as mean and median and so on. The generalized quasi-likelihood estimate obtained by such a
generalized quasi-score function is consistent and has an asymptotically normal distribution. As a result, the optimum generalized
quasi-score is obtained and a method to construct the optimum unbiased basis function is introduced. In order to construct
the potential function, a conservative generalized estimating function is defined. By conservative, a potential function for
the projected score has many properties of a log-likelihood function. Finally, some examples are given to illustrate the theoretical
results.

Starting with its early twentieth century origins, the development of Labor Economics is traced to the present. We describe
an intellectual revolution in which an earlier tra-dition that focused primarily on the institution of the labor union has
been replaced by a perspective that emphasizes the various roles played by labor markets in an eco-nomic system. That earlier
tradition contained very significant ideological elements, whereas its successor deals much more with the world of ideas.
In the course of the debate, which still continues, ideas triumphed over ideology and created modern Labor Economics. 相似文献

We show that Bayesian ex post aggregation is unstable with respect to refinements. Suppose a group of Bayesians use ex post
aggregation. Since it is a joint problem, each agent's problem is captured by the same model, but probabilities and utilities
may vary. If they analyze the same situation in more detail, their refined analysis should preserve their preferences among
acts. However, ex post aggregation could bring about a preference reversal on the group level. Ex post aggregation thus depends
on how much information is used and may keep oscillating (“flipping”) as one keeps adding more information.

In a general model of indivisible good allocation, S?nmez (1999) established that, whenever the core is nonempty for each
preference profile, if an allocation rule is strategy-proof, individually rational and Pareto optimal, then the rule is a
selection from the core correspondence, and the core correspondence must be essentially single-valued. This paper studies
the converse claim of this result. I demonstrate that whenever the preference domain satisfies a certain condition of `richness',
if the core correspondence is essentially single-valued, then any selection from the core correspondence is strategy-proof
(even weakly coalition strategy-proof, in fact). In particular, on the domain of preferences in which each individual has
strict preferences over his own assignments and there is no consumption externality, such an allocation rule is coalition
strategy-proof. And on this domain, coalition strategy-proofness is equivalent to Maskin monotonicity, an important property
in implementation theory.

在对隐喻真值条件的探讨中,吉纳比与斯坦哈特分别基于范畴归属和可类比性刻画了纯粹的语义真值条件。如果把讨论延伸至句法和语用,将能更深入地反映隐喻的生成和理解。真值条件语用学认为,语句的完整语义可以视为其组成部分经语境调适的内容(及其组合方式)的函数。在范畴类型理论框架下,该调适过程具体可以通过赋予表达式不同的范畴和相应的类型来体现。就隐喻语句而言,语境的调适体现为转变源域类型和限制隐喻函数对性质的选择,首先将源域的类型由个体集转化为性质集,然后通过一个从性质集到个体集的隐喻函数,在源域性质集中提取符合语境的特征性质,如果目标域中的对象满足这一提取出的性质,则隐喻语句为真。 相似文献
