储油罐的变位识别与罐容表标定研究

通常加油站都有若干个储存燃油的地下储油罐,并且一般都有与之配套的"油位计量管理系统",但是由于地基变形等原因,罐体会发生横向和纵向的偏斜。本文建立了数学模型对罐容量进行了重新标定。在小椭圆储油罐中,对油罐中油的形状进行了分类讨论。研究探讨了罐内储油量与油位高度及变位参数(纵向倾斜角度α和横向偏转角度β)之间的一般关系,通过模拟结果发现实验值与观察值的结果相关性很高(相关系数超过0.99)。     

Sources of support and expatriation: a multiple stakeholder perspective of expatriate adjustment and performance in Malaysia

This research tests the role of perceived support from multinational corporations and host-country nationals for the adjustment of expatriates and their spouses while on international assignments. The investigation is carried out with matched data from 134 expatriates and their spouses based in foreign multinationals in Malaysia. The results highlight the different reliance on support providers that expatriates and their accompanying spouses found beneficial for acclimatizing to the host-country environment. Improved adjustment in turn was found to have positive effects on expatriates' performance. The research findings have implications for both international human resource management researchers and practitioners.     

Organizational identification as a determinant of customer orientation in service organizations

The marketing literature suggests that frontline employees are the central determinant of how customer-oriented a service organization is perceived to be by its customers. However, little is known about the contingencies of employees’ customer orientation (CO) beyond personality traits and broadly construed work attitudes. Based on the social identity approach, the present article develops a multilevel model whereby CO is the result of identity-based management of frontline employees. Two empirical studies in the travel industry show that employees’ CO depends on employees’ organizational identification and their leaders’ acting as role models of CO.     

The Role of the Global Reporting Initiative's Sustainability Reporting Guidelines in the Social Screening of Investments

Social screening of investments calls not only for investment policy and criteria, but also for information about companies, their policies, practices and performance. The Global Reporting Initiative (GRI) and its June 2000 Sustainability Reporting Guidelines have the potential to significantly improve the usefulness and quality of information reported by companies about their environmental, social and economic impacts and performance. The GRI aims to develop a voluntary reporting framework that will elevate sustainability reporting practices to a level equivalent to that of financial reporting in rigour, comparability, auditability and general acceptance. This will be a welcome and efficient supplement to the questionnaires, interviews, press releases, media reports and other sources of information traditionally used for screening in investment decision making – social/ethical and mainstream. The Dow Jones Sustainability Group Index, the Jantzi Social Index and the Innovest EcoValue'21 analytical platform, together with the SRI community, are all likely to benefit from GRI-style sustainability reports. One of the GRI's key challenges is to accommodate the broad variety of disclosure needs and expectations of a wide range of report users and company stakeholders. To maximize the usefulness of the GRI Guidelines, report users, including the SRI community, need to be engaged in the process of developing and refining the Guidelines over time. The GRI Guidelines are emerging as an important instrument in enabling companies to communicate with their stakeholders about performance and accountability beyond just the financial bottom line.     

一种一维距离像的识别算法

随着高分辨率雷达的发展,一维距离像识别已成为雷达目标识别的重要方法之一.为了消除一维距离像的平移,将一维距离像变换到频域,提取其频谱信息作为识别特征,并依据Fisher判据,将高维特征空间数据降到一维空间,提高了算法的实时性.仿真结果表明这是一种方便有效的识别方法.     

企业契约的利益相关者模型

企业是利益相关者参与的一系列契约的联结.利益相关者包括股东、经理人员、债权人、供应商、消费者、工人以及社会公众等,他们将自己所拥有的资源投入到企业,同时也就拥有了不同的企业所有权.企业所有权包括索取权(包括固定索取权、变动索取权和剩余索取权)和控制权(包括固定控制权和剩余控制权),而企业所有权安排则是在制度环境、供求关系、资源投入量、资源的信号显示机制、资源可抵押性、资产专用性、风险选择和组织化程度等因素的影响下,利益相关者利益冲突与协调的结果.这些因素的不断变化之特征,决定企业所有权安排是一个动态的过程,它具有状态依存特征.

组织认同研究述评及展望

组织认同(organizational identification)在西方已成为组织行为研究的重要概念和关键变量,而我国对这一领域的研究还刚刚起步。有必要对组织认同的概念内涵进行辨析,并对组织认同的前因和结果变量以及组织认同的类型进行系统研究。还要对我国组织认同研究的初步成果进行系统回顾,并提出我国组织认同研究的发展方向。     

The Ethical Dimensions of Decision Processes of Employees

The influence of stakeholders, organisational commitment, personal values, goals of the organisation and socio-demographic characteristics of individuals on the ethical dimension of behavioural intentions of employees in various organisations are investigated. The research results show that employees working for the public sector or in educational institutions take more ethical aspects into account than employees working in the "private" sector. The influence of stakeholders and organisational commitment do not significantly affect the ethical behaviour of employees, and only some personal values and goals of the organisation have a significant influence on ethical behaviour. The most significant explanatory factor of ethical decision making seems to be what may be called "stage in the career of the employee": "ethical" employees can be described as young, with a relatively low income, limited work experience and a low level of responsibility in the company.     

Globalization and the Good Corporation: A Need for Proactive Co-existence

Large corporations are coming under intense pressure to act in a socially responsible manner. Corporations have accepted this notion provided that it is exercised voluntarily. It has also been argued that corporations can do well by doing good, and that good ethics is good business. This paper presents an alternative viewpoint by demonstrating that while voluntary socially responsible conduct is desirable, it plays a rather small role in inspiring good corporate conduct. Instead, (a) it is the external economic-competitive conditions that define the parameters and opportunities for good corporate conduct; and (b) the values and traditions of the corporations, and their perceived risk in exploiting those opportunities, that influence the extent of a corporation's socially responsible conduct. The framework presented here analyzes certain market-competitive conditions, which determine the scope and direction of socially responsible corporate conduct, and the instruments available to society to enhance ethical corporate conduct. It suggests that from society's perspective, we should move away from the notion of corporate social responsibility and toward corporate social accountability. Most modern economies operate under conditions of imperfect competition where corporations gain above-normal profits, i.e., market rent, from market imperfections. Therefore, corporations should be held accountable for a more equitable distribution of these above-normal profits with other groups, e.g., customers, employees, etc., who were deprived of their market-based gains because of market imperfections and corporate power. Three approaches are suggested for measuring corporate accountability through corrections. These are: information imbalance, bargaining power imbalance, and, adjudication, remedy and relief imbalance.
