On the recovery of intra- and interblock information in n-ary designs

This note presents an extension of Q-method of analysis for binary designs given by Rao (1956) to n-ary balanced and partially balanced block designs. Here a linked n-ary block (LNB) design is defined as the dual of balanced n-ary (BN) design. Having a note on Yates’ (1939, 1940) method of P-analysis, we further extend the expressions for binary linked block (LB) designs given by Rao (1956) to linked n-ary block (LNB) designs which admit easy estimation of parameters for these type of all n-ary designs.

Housing Policy and the Elderly

Subsidized senior high-rise apartments have tended to neglect the needs of an increasingly aged and frail resident population. Research demonstrates that this population has greater unmet needs than elderly who reside in traditional community housing. This paper makes the case for enriched senior high-rise apartments as a viable alternative for elders who need assistance in order to maintain an independent lifestyle.     

＂片言可以折狱＂源于孔子对子路的绝对信任

历代注家对〈论语·颜渊〉篇＂片言可以折狱,其由也与.子路无宿诺＂一章的注释大致可以分为三种：1.孔子美子路可以只凭单方面的言辞断案,因为子路是一个信守承诺的人.2.孔子美子路三言两语就可以断清一个案子,＂子路无宿诺＂应另作一章,与前文没有关联.3.孔子美子路笃信不欺,只听子路单方面的言辞就可以对一件事情作出判断.大多数注家都倾向于第一种理解.由于只听单方面的言辞就断案,这实在不合常理,因此也引来很多质疑.通读〈论语〉全书,结合历史事实,第三种注解更为符合事实.     

Bounding the resampling risk for sequential Monte Carlo implementation of hypothesis tests

Sequential designs can be used to save computation time in implementing Monte Carlo hypothesis tests. The motivation is to stop resampling if the early resamples provide enough information on the significance of the p-value of the original Monte Carlo test. In this paper, we consider a sequential design called the B-value design proposed by Lan and Wittes and construct the sequential design bounding the resampling risk, the probability that the accept/reject decision is different from the decision from complete enumeration. For the B-value design whose exact implementation can be done by using the algorithm proposed in Fay, Kim and Hachey, we first compare the expected resample size for different designs with comparable resampling risk. We show that the B-value design has considerable savings in expected resample size compared to a fixed resample or simple curtailed design, and comparable expected resample size to the iterative push out design of Fay and Follmann. The B-value design is more practical than the iterative push out design in that it is tractable even for small values of resampling risk, which was a challenge with the iterative push out design. We also propose an approximate B-value design that can be constructed without using a specially developed software and provides analytic insights on the choice of parameter values in constructing the exact B-value design.

“浙商”海外非商业风险及避险机制分析

近年来,随着国际形势不确定因素的增加以及世界经济的不稳定,＂浙商＂海外非行商风险日益凸显,不断遭遇特定行政限制、恐怖袭击、绑架等非商业风险,其海外安全状况令人担忧。因此,提高＂浙商＂安全意识,强化海外风险防范能力,构筑避险机制,既是＂浙商＂自身发展的需要,也是各级政府落实＂以人为本,执政为民＂理念的具体表现。

Sri Lanka: an exploration of the systemic erosion of stability

Abstract

In Sri Lanka tremendous expertise is employed in thinking and manoeuvring around the personalities that shape the outcomes that beset the country. Such expertise is the bread and butter of the political and business circles, which is equally well reflected in the media and realistically respected in the NGO and international circuit.

What is disconcerting however is the almost oblivious attention paid to matters of structure and functionality. Yet Sri Lanka is rife with structural and functional anomalies, which is positioned to terminally gnaw at advantages gained by changes in governments, peace talks, poverty reduction, etc. Using the example of the Public Administration System and the democratically elected Presidential and Parliamentary process explained is the structural and functional impediments that are crying out for serious remedy.

There is a vital homeostatic balance that is exercised between the parliament and the Public Administration System as a result of the former being elected and the latter employed on tenure. This translates to the Public Administration System being able to afford to think long term (since their tenure is secure) whilst being tempered by parliament's shorter range thinking occasioned by the politician's need to show results to entice its next bout of votes. In essence, this twofold structure serves to foster the seeking of a homeostatic balance between the long-and short-term needs of the country.

In Sri Lanka by constitutional and other legislative enactments various homeostatic relationships between races, languages, time spans etc. have been (un)wittingly flouted. These aspects are diagnosed using the cybernetic concepts of homeostasis and ultrastability.     

儒家教育思想的当代价值

中国教育文化源远流长，儒家思想作为其中的的主流，对后世产生十分深远的影响。儒家教育思想包含诸多的方面，其中如以人为本、有教无类、身教示范等观点在当代社会仍有巨大的借鉴价值和启示意义。继承和发扬这笔宝贵的历史文化遗产对于我们更好地开展教育教学工作，发扬社会主义精神文明是十分必要的。
