On second-order improved estimation of a gamma scale parameter

This paper concludes our comprehensive study on point estimation of model parameters of a gamma distribution from a second-order decision theoretic point of view. It should be noted that efficient estimation of gamma model parameters for samples ‘not large’ is a challenging task since the exact sampling distributions of the maximum likelihood estimators and its variants are not known. Estimation of a gamma scale parameter has received less attention from the earlier researchers compared to shape parameter estimation. What we have observed here is that improved estimation of the shape parameter does not necessarily lead to improved scale estimation if a natural moment condition (which is also the maximum likelihood restriction) is satisfied. Therefore, this work deals with the gamma scale parameter estimation as a separate new problem, not as a by-product of the shape parameter estimation, and studies several estimators in terms of second-order risk.     

Implementation of just-in-time methodology in a small company

This paper describes the implementation of JIT in a small manufacturing company and the benefits that resulted for the company's operations. Preliminary analysis identified various problems in the existing manufacturing operations. The pre-implementation and post-implementation conditions of the company arc detailed. The achievements of the JIT implementation included a reduction in material traversing, reduced lead limes and inventories leading to an overall reduction in the cost of manufacturing. A smooth flow of material from the raw material stage to the finished product stage was established. Three separate product lines were combined into a flexible manufacturing assembly line. With the adoption of a holistic approach to JIT implementation, it was found that even a small company can make significant strides towards world class manufacturing status. The experience gained by the company can encourage and benefit other small companies to embrace the JIT approach.     

The effect of non-normality on estimating the variance of the combined ratio estimate in complex surveys

The performance of the balanced half-sample, jackknife and linearization methods for estimating the variance of the combined ratio estimate is studied by means of a computer simulation using artificially generated non-normally distributed populations.

The results of this investigation demonstrate that the variance estimates for the combined ratio estimate may be highly biased and unstable when the underlying distributions are non-normal. This is particularly true when the number of observations available from each stratum is small. The jack-     

基于供应链集成的网络式新产品开发研究

基于供应链集成的网络式新产品开发，不是从一个企业或企业集团层面看，而是从整个产业的层面看，那就是新产品开发是由产业内价值链相关各企业及企业外部研发资源，利用企业间的互动机制，相互创意激发及技术交流而产生新产品的一种模式，这种模式的最大优势是全体参与者的共同参与，发挥全体参与者团体作用的优势，强调产品开发流程，以产出为衡量基准，强调“产出成本效率”的业绩评估体系以及通过对外部资源的充分利用，强调“资源优化和无缝对接”和有效配套管理。     

外商直接投资在中国经营方式变迁的新制度经济学分析

通过回顾外商直接投资在中国经营方式的变迁,认为经营方式的独资化趋势是一种自上而下以渐进式发生的强制性制度变迁,是在中国政府政策引导下的有微观主体自愿参与的制度变迁。运用新制度经济学的研究方法,通过对谈判结构和交易成本的分析,揭示了这一变迁的原因在于：合营企业和合作企业与外资企业在设立与运营过程中由于谈判结构的不同,而使后者在产权保护以及协议执行的成本更低,从而导致了外商直接投资在中国的独资化趋势。认为中国政府应出台政策提高利用外资的质量和水平,以降低＂独资化＂带来的负面影响。     

Interdisciplinary Practice in Developmental Disabilities

ABSTRACT

This article explores the development of interdisciplinary team practice within the field of development disabilities. Various interdisciplinary models are described, and the role of the social worker is specifically reviewed. As social workers practice as members of teams in a variety of contexts, a greater understanding of an interdisciplinary approach is warranted.     

媒体关注下的CSR信息披露与企业财务绩效关系研究及启示——基于我国A股上市公司CSR报告的实证研究

企业社会责任(CSR)及信息披露已成为当前社会各界共同关注的热点问题。本文利用独立机构发布的我国A股上市公司CSR报告的评级数据,验证了当前时代背景下我国企业社会责任信息披露与企业财务绩效的关系,以及作为信息传递媒介和"公众日程设置者"的媒体的关注对于二者关系的影响作用。研究发现,高水平披露社会责任信息的企业的绩效明显高于低水平企业,但是这种作用关系是在媒体关注度这一变量的完全中介作用之下实现的。这一新发现不仅丰富和拓展了企业社会责任及信息披露的理论研究框架,对于基于战略性CSR思维制定相关战略的企业管理者也深具启发意义。     

Enriching Resources for the Poor: Lessons from the Philippines

The paper provides an overview of the poverty situation in the Philippines, followed by a brief profile and assessment of two anti‐poverty programs: the Kapit‐Bisig Laban sa Kahirapan‐Comprehensive and Integrated Delivery of Social Services (KALAHI‐CIDSS) program and the Pantawid Pamilyang Pilipino Program (4Ps). Official statistics disclose that the global economic crisis in 2008 adversely affected Filipino households, leading to higher levels of poverty especially in rural areas. In response, government introduced an Economic Resiliency Program with social protection as one component. Sixty‐six social protection programs were launched, including the two under review. KALAHI‐CIDSS and the 4Ps apply poverty reduction strategies that focus on the development of human and social capital, rather than economic capital. They involve processes and relationships that aim to improve the other dimensions of poverty, such as lack of access to opportunities or deprivation of basic human necessities. Qualitative and quantitative reports describe generally favorable outcomes from both programs. However, these gains at the household level need to be supported by relevant policy, enhanced public services and badly‐needed infrastructure programs from government, in order to sustain achievements culled from social protection programs and attain broader developmental impacts.

秦、西汉的“内臣”与“外臣”

本文对文献记载中西汉政权处理民族关系时出现的“内臣”和“外臣”作了分析 ,归纳了它们在与中央政权关系上各自不同的特点。作者在分析云梦睡虎地秦简的基础上认为 ,秦简中的“臣邦”相当于汉代“内臣” ,“外臣邦”相当于汉代“外臣” ;并指出文献中的“羁縻”制度等同于“外臣” ,“葆塞蛮夷”相当于“内臣” ;同时提出“内诸侯”和“外诸侯”的称呼不适合于汉代分封和民族政策 ,应以汉代习称的“内臣”和“外臣”为准。最后 ,本文归纳了“外臣”向“内臣”转化的途径和原因 ,提出中央政权军事力量的壮大是完成此转化的直接动力。
