消费者异质性下供应链互补产品销售策略选择及其定价研究

基于消费者对互补品消费习性存在的异质性,对互补品消费市场进行细分,并在上游两个制造商分别提供具有互补特性的产品,下游一个销售商同时销售这两种产品的供应链环境下研究定价均衡。根据不同目标市场选择,识别出全市场覆盖以及聚焦细分市场两种销售策略,分别对两种营销策略下的供应链产品定价进行讨论,并通过模型求解分别得到两种策略下的均衡,讨论了两个均衡解存在的条件,讨论了均衡定价随产品互补程度以及互补品相对效用比的变化情况,以及销售商在不同情形下选择的定价策略。结果表明,当互补品相对效用差异不大,且互补程度不大的时候,渠道内形成第一个定价均衡;当产品间相对效用差异大,且互补程度足够大的时候,渠道内形成第二个定价均衡。     

Codes of Ethics: What Are They Really and What Should They Be?

Codes of ethics are prevalent in major corporations around the world. They are seen as the first tangible commitment to being ethical. This paper examines codes of ethics and tries to establish what they are, how they are developed and their net utility. We then proffer the idea of codes as the first part of a five-stage process that leads to an overall corporate commitment to being ethical in one's business dealings.     

区间数互补判断矩阵的一致性及其排序研究

由于目前国内外文献对区间数互补判断矩阵的性质研究较少,从而使得对排序方法的相关研究缺乏理论依据.针对这些缺陷,本文研究了区间数互补判断矩阵的性质及其排序方法问题.根据区间数互补判断矩阵的定义,给出了区间数互补判断矩阵的一致性、严格强传递性与弱传递性等定义,并研究了一致性判断矩阵的性质,并说明这些性质更符合人们的思维特征.在一致性性质的基础上建立了区间数互补判断矩阵排序的非线性规划模型,算例分析表明该方法是有效可行的.     

From Codes to Contextual Collaborations: Shifting the Thinking About Ethics in Social Work

In this article, the authors argue that the current emphases in social work on codes, standards, and decision-making models are insufficient to the task of ensuring ethical relationships between workers and clients. Three fundamental assumptions that underpin codes and standards are analyzed. The authors then explore the nature of ethical relationships and demonstrate how codes and standards, in their current form, do not address the complexity and contextuality of the social work relationship. After considering why the profession relies so heavily on codes and standards, they call for a re-thinking of ethical relationships, offering ideas and recommendations for those relationships.     

A comparison of social work education across South Africa and Japan in relation to the Global Standards for Social Work Education and Training

Sakaguchi H, Sewpaul V. A comparison of social work education across South Africa and Japan in relation to the Global Standards for Social Work Education and Training Int J Soc Welfare 2011: 20: 192–202 © 2009 The Author(s), International Journal of Social Welfare © 2009 Blackwell Publishing Ltd and the International Journal of Social Welfare. This article draws on a one‐year study visit to the University of KwaZulu‐Natal, South Africa, interviews with field supervisors and students in Japan and reviews of the national frameworks of education in Japan and in South Africa. In doing so, the authors identify the similarities and differences in social work education across the two countries and they explore some of the historical and socio‐cultural factors that might account for the differences. There are some identifiable peculiarities in social work education in Japan, especially with the coalescing of care work and social work education. The lack of differentiation between care work and social work makes it difficult to narrow the scope of social work education and practice. National social work standards have been approved in South Africa and regulatory frameworks for social work education and practice have been long accepted, thus rendering ‘social work’ a protected title and a profession that is more entrenched compared with social work in Japan. The codes of ethics in Japan and South Africa are discussed with specific reference to their control functions in South Africa. The article concludes by discussing these comparisons in relation to the Global Standards for Social Work Education.     

Beyond bureaucracy and entrepreneurialism: Examining the multiple discursive codes informing the work,careers and subjectivities of management graduates

This paper examines how discursive codes and demands associated with ‘bureaucratic and entrepreneurial regimes’ of work and career organization shape the work, careers and subjectivities of management graduates. The study is based on an analysis of 30 narratives of management professionals who graduated from an Austrian business school in the early 1970s or 2000s. Its insights suggest that variegated discursive codes manifest in the graduates’ articulated professional practices and subjectivities, thereby challenging established assumptions regarding the organization of work and careers. While the practices and subjectivities of the 1970s graduates are often informed by codes and demands ascribed to ‘entrepreneurialism’, those of the 2000s graduates are infused with several codes commonly portrayed as ‘bureaucratic’.

LGBTQ Women,Appearance Negotiations,and Workplace Dress Codes

The purpose of this study was to explore LGBTQ women’s experiences with unwritten or formal dress codes at work. I asked: What are LGBTQ women’s experiences in the workplace with appearance management, and what are LGBTQ women’s experiences navigating the written and unwritten dress codes in the workplace? To answer the research question, interviews were conducted with 24 self-identifying LGBTQ women. Six key themes emerged from the data. Themes included (1) expressed sexual identity in appearance, (2) unwritten dress codes in work environments did not always allow for expression of sexual identity in appearance, (3) motivations for pressure or desire to conceal expression of sexual identity in appearance at work, (4) negotiations of revealing or concealing sexual identity in appearance in the workplace impacted levels of comfort and confidence, (5) verbal and nonverbal negative experiences related to appearance at work, and (6) received compliments about appearance at work.     

A closer look at de-aliasing effects using an efficient foldover technique

Foldover techniques are used to reduce the confounding when some important effects (usually lower order effects) cannot be estimated independently. This article develops an efficient foldover mechanism for symmetric or asymmetric designs, whether regular or nonregular. In this paper, we take the uniformity criteria (UC) as the optimality measures to construct the optimal combined designs (initial design plus its corresponding foldover design) which have better capability of estimating lower order effects. The relationship between any initial design and its combined design is studied. A comparison study between the combined designs via different UC is provided. Equivalence between any combined design and its complementary combined design is investigated, which is a very useful constraint that reduce the search space. Using our results as benchmarks, we can implement a powerful algorithm for constructing optimal combined designs. Our work covers as well as gives results better than recent works of about 20 articles in the last few years as special cases. So this article is a good reference for constructing effective designs.
