A procedure for testing the equality of k dependent correlation coefficients

A procedure is proposed for testing the equality of k dependent correlation coefficients. The procedure is simulated utilizing Monte Carlo techniques; and, a method for post hoc probing is also suggested.     

Curation: a theoretical treatment

Curation is a key mechanism of sociality in a digital era. With an abundance of information, sifting, sorting, selecting, hiding, and standing out become laborious tasks. While researchers have diligently documented people’s curatorial strategies, digital curation remains undertheorized in its own right. I therefore theorize digital curation by disentangling productive curation from consumptive curation, addressing how people curate content that they share, and that which they consume. I embed these agentic curatorial practices within structural bounds, both social and technological. In doing so, I offer a basic theoretical model that captures a dynamic relationship between individual curators, their social networks, and technological design.     

胡尖山地区长 6、长 4+5 储层有利区预测

摘要：以胡尖山油田长 6、长 4+5 油藏为例，综合应用地质资料、岩芯分析资料、测井资料以及试油资料，开展了长 6和长 4+5 油藏小层划分和对比、单井相分析，建立测井相识别模式，编制小层沉积相平面展布图，进而分析沉积相演化规律；探讨储层砂体展布以及物性分布规律，从而深入认识研究区的储层特征。在此基础上对储层进行流动单元的划分，然后结合试油资料对胡尖山油田长 6、长 4+5 油藏的储层进行有利区域的预测，为油田待开发区域的合理建产开发提供了理论指导     

Producing information: communication and collaboration in the South African scientific community

Prior research has investigated the relationships between communication, collaboration and production of information/knowledge. Most of this research has been conducted either in developed countries where the internet facility is highly advanced or in developing countries with little internet access. Investigations in countries that fall in between these two extremes are rare. This study of respondents from higher education institutions and research institutes examines the relationship between collaboration and internet use, as well as productivity and internet use in the South African scientific system which has become a strong contributor to science in Africa.     

基于长沙市T区社区管理模式现状的思考

以长沙市T区为分析案例,通过对T区进行调查研究,寻找当前长沙市社区管理模式存在的一些问题:管理体制的行政化,政府职能的错位与缺位,居民与社区中介组织参与社区管理程度低,社区工作任务繁重,等等。要解决当前社区管理存在的一系列问题,必须重新考析政府、社区、社区中介组织以及居民之间的关系,理顺社区管理体制,明确政府职能,大力培育社区中介组织,培养居民的参与意识,构建长沙市功能型社区管理模式。     

“期刊承认”VS“共同体承认”:我国学术知识生产动力机制的“悖论”

"共同体的承认"是知识生产的根本动力,在西方"期刊承认"乃"共同体承认"的有机组成部分,学术人努力生产、发表创新性的知识以赢得"共同体的承认".然而在我国,量化考评下的"期刊承认"并未得到大部分学术人的真正认同,已非"共同体承认"的一部分,学术人生产知识主要是为了取得形式化的"期刊承认"以满足各种实用性的目的,而非生产出创新性的知识以赢得实质性的"共同体承认","期刊承认"与"共同体承认"之间的冲突导致了我国学术知识生产动力机制的失灵.为了化解两者之间矛盾,我们一方面应使"同行评议"机制在各种学术评价活动中占据主导地位,另一方面要进一步完善学术期刊的"匿名评审"制度,以弥合"期刊承认"与"共同体承认"之间的断裂,从而真正激励学术知识的生产.     

Production and changeover control policies of a class of failure prone buffered flow-shops

This article deals with a stochastic optimal control problem for a class of buffered multi-parts flow-shops manufacturing system. The involved machines are subject to random breakdowns and repairs. The flow-shop under consideration is not completely flexible and hence requires setup time and cost in order to switch the production from a part type to another, this changeover is carried on the whole line. Our objective is to find the production plan and the sequence of setups that minimise the cost function, which penalises inventories/backlogs and setups. A continuous dynamic programming formulation of the problem is presented. Then, a numerical scheme is adopted to solve the obtained optimality conditions equations for a two buffered serial machines two parts case. A complete heuristic policy, based on the numerical observations which describe the optimal policies in system states, is developed. It will be shown that the obtained policy is a combination of a KANBAN/CONWIP and a modified hedging corridor policy. Moreover, based on our observations and existent research studies extension to cover more complex flow-shops is henceforth possible. The robustness of such a policy is illustrated through sensitivity analysis.     

论消费在国际传媒生产总过程中的地位

在国际传媒生产贸易中，传媒产品消费的本质就是价值认可式的精神性消费，在自愿获得消费物的消费中，得到精神与心灵上的满足，实现对一国传媒产品的最优化接受。由此本质出发，总结了消费的六种类型，在分析梳理其逻辑关系的基础上，论证了消费在国际传媒生产总过程中的主导地位。     

限量促销诱发的前瞻性情绪及其作用机制

摘要:为探讨限量促销诱发的前瞻性情绪及其对购买意愿的作用机制,根据促销决策及目标导向型决策理论,在将前瞻性情绪分为“希望、焦虑、预期欣喜和预期后悔”的基础上,结合限量方式、产品类型及限制数量3个因素,借助5个心理学实验进行检验.研究发现:1)生产型限量与销售型限量方式对前瞻性情绪及购买意愿的影响有显著差异,且生产型限量的影响更大;2)限量方式对前瞻性情绪及购买意愿的影响会受到产品类型的调节.炫耀品更适合使用生产型限量促销,非炫耀品更适合使用销售型限量促销;3)在炫耀品情境下,限量方式对前瞻性情绪及购买意愿的影响会受到限制数量的调节;4)在炫耀品情境下,一元线性回归结果显示,希望、焦虑、预期欣喜、预期后悔对购买意愿的影响都显著,但多元线性回归显示,希望的影响最大,预期后悔与预期欣喜紧随其后,而焦虑则不显著.以上研究结论不仅对企业提升限量促销效果有益,而且有助于深入理解前瞻性情绪的作用.     

非常时期列宁关于粮食生产和农村工作的思想及其当代意义

苏俄非常时期,列宁在解决粮食危机的过程中提出了十分丰富的发展粮食生产及农村工作的思想。他提出,“粮食问题是一切问题的基础”,进行国内战争、发展工业以及各项事业,无不依赖于充足的粮食;发展粮食生产必须重视对农业生产的投入,采用新机器和新技术;必须帮助农民获得足够的种子,以利于他们完成播种的任务。他还提出,发展粮食生产需要调动农民的生产积极性,依赖有效的农村工作。他的这些思想对于中国特色社会主义农村建设具有积极的借鉴意义。
