读殷墟花园庄甲骨卜辞

本文就最近刊布的殷墟花园庄出土卜辞,讨论了下述三个问题：1.卜辞书刻省略例证;2.一种先祖祭祀的特殊祭序;3.进献割裂的牺牲是商代宗庙祭礼的主要仪法。     

债法外观法理研究——以债务人对债权准占有人清偿为中心

债务人对债权准占有人清偿,即债务人对债权文书持有人清偿,其清偿若符合善意且无过失的要求,该清偿行为发生债消灭的效力,效力依据对债务人来说在于对债权准占有人受领权外观的合理信赖,对债权人来说是其引致该受领权外观所应承担的权利表见责任,二者构成债法外观法理的核心。债法外观法理同样是债务人对于除债权准占有人以外的其他表见债权人清偿有效的法理基础。     

Likelihood based inference for the ratio of gamma means

Inference concerning the ratio of two means based two independent two-parameter gamma models with common shape parameter was examined in Booth et al. (rid="b4" data-refLink="_i43" href="#">1999 Booth, J. G., Hobert, J. P. and Ohman, P. A. (1999). On the probable error of the ratio of two gamma means. Biometrika, 86: 439–452.  ref="http://scholar.google.com/scholar_lookup?hl=en&volume=86&publication_year=%281999%29&pages=439-452&author=J.+G.+Booth&author=J.+P.+Hobert&author=P.+A.+Ohman&title=On+the+probable+error+of+the+ratio+of+two+gamma+means" target="_blank">[Google Scholar]) and a computationally intensive bootstrap calibration method was developed. In this paper, a likelihood based method is proposed for small sample inference about the ratio of two means of the two-parameter gamma models when the shape parameters may or may not be equal. The proposed method is very simple to use and, as illustrated in simulation studies, gives extremely accurate results.

In this paper Monte-Carlo methods are used to compare the small-sample variances of two such estimators with those of the mean, the median and the Hodges–Lehmann estimator. These comparisons are made for samples of size n=7(1)5 and for six different source distributions.     

Note on “The Backroom Effect in Retail Operations”

Eroglu et al. (2013) study a retailer with limited shelf capacity and a backroom. They study a continuous review (r, q) ordering policy with a known order quantity, q. Assuming that backorders can be satisfied from the backroom inventory (if available), they find the expression for the optimal reorder level, r. Our work builds on Eroglu et al. (2013). We correct an erroneous derivation of the expected overflow term, as well as derive an exact expression for the expected cost function, and hence optimal reorder level, instead of the approximate one used by Eroglu et al. (2013).     

论中国风险投资的制度缺陷

我国风险投资业的制度缺陷：从外部投资者与风险投资家 的关系来看，一是合伙制没有得到实行，风险投资的运作行政化；二是融资制度缺乏选择机 制；三是分配制度缺乏激励风险投资家的机制；从风险投资家与风险企业的关系来看，一是 风险投资家不能为风险企业提供增殖服务，从而出现事实上对风险企业的逆向选择；二是风 险投资家难以介入风险企业的经营决策，加上作为代理人的风险投资家的偷懒行为，难以防 范所投资企业的道德风险；从风险投资的制度环境来看，一是退出渠道不畅，使风险投资望 而却步；二是法律制度不健全，导致投资人利益得不到保障。     

The 1970 US draft lottery revisited: a spatial analysis

Summary.  We revise the result of the 1970 selective service draft lottery in the USA following an open question that was suggested by Fienberg in a paper published in Science in 1971. The result of the drawings can be viewed as a particular spatial pattern which can be analysed by using general spatial tools adapted to our context. Approaches for assessing the complete spatial randomness for this spatial process on a finite support are proposed. More specifically, these approaches involve the number of events in a square window and a k ( r )-based function used to analyse stationary spatial point processes.     

Another chapter in the story of /r/: ‘Labiodental’ variants in British English

In this article we trace the history of [bnu;]-like variants of British English /r/. Although [bnu;] has generally been dismissed as an infantilism, or indicative of affected or disordered speech, it seems to have become established as an accent feature of non-standard south-eastern accents. We present tentative evidence to suggest this may be related to the presence of similar variants in the London East End Jewish community. After summarising previous discussions of [bnu;], we concentrate on a sociophonetic study of /r/ variants used by speakers from Derby and Newcastle. [bnu;] is found in both cities, with a higher incidence in Derby. Acoustic evidence suggests that the spreading variants are qualitatively different from [?]. We conclude that the spread of [bnu;] is part of a general and widespread process of accent levelling.     

汪容甫与章实斋交谊及学术异同考论

汪容甫与章实斋有三次共事的经历,两人最初交恶是在第一次共事朱筠幕府期间;"议论不合"是他们矛盾产生的主要原因;实斋始以容甫为"畏友",后视之为"妄人",是其学术发展和心态变化的反映;汪、章两人学术都深受戴震学术的影响,多有相通之处,但也有区别,具体表现在学术路径、治学理念、致思方向、经世之志等方面。     

Comparison of experiments based on generalized entropy measures

Taneja (1989) studied a unified (r,s)-entropy which includes as a particular case some of the known entropies. Based on this unified (r, s)entropys we have defined the average amount of information provided by an experiment X over the unknown parameter 8 with prior knowledge p(0). By using average amount of information in unified form, we have compared experiments based on bayesian approach. Some connections with the criteria of Blackwell and Lehmann are also made.
