方正断陷三维区油气聚集规律特征

方正断陷位于松辽盆地东侧的依-舒地堑中北段,为一个一级负向构造单元。根据钻井资料,结合地震资料对研究区油气成藏条件进行综合分析,认为该区具备良好的生储盖组合条件,圈闭条件较好,油气藏的类型主要为构造油气藏和岩性油气藏。通过对各主要目的层的构造特征,相带展布规律及储层发育特征,结合钻探成果进行综合分析,结果表明:伊汉通断裂是本区油气运移的主要通道,伊汉通断裂两侧发育的圈闭、新安村+乌云组下部发育的岩性圈闭、柞树岗次凹斜坡处发育的岩性圈闭、达连河组发育的岩性圈闭及其顶面发育的构造圈闭是油气聚集的主要场所。

Developments in human resource management in manufacturing in modern Britain

In this paper, developments in human resource management in manufacturing in modern Britain based on a national sample are examined. The organization and role of human resource management, employee involvement, training and development, work practices and rewards are all targeted for an assessment of current practices. This is a prelude for a contrast between manufacturing and non-manufacturing. The conclusion is that the similarities between manufacturing and non-manufacturing substantially outweigh the differences. By inference, too, developments in human resource management practices are likely to reflect changes in the broader environment of businesses (and differences between companies) rather than being specific to the main industrial sectors.     

Accounting in transition in the transitional economy

The paper provides a theoretical construct as a frame of reference for understand-ing the possibilities for, and the nature of, accounting change in the former socialist countries of Central and Eastern Europe. Within its context some of the practical issues arising from the accounting reform measures are considered.     

The intranet's role in newcomer socialization in the hotel industry in Taiwan – technology acceptance model analysis

This study examined a research model for explaining the relationships of intranet adoption and newcomers' organizational socialization in the hotel industry. Data were gathered for a structural equation model (SEM) analysis, from 298 individual participants, who had only worked in a hotel for 6 months to 1 year. The research results demonstrated the mediation role of the perceived usefulness (PU) and perceived ease of use of the intranet. The SEM results also revealed that usage of the intranet did increase the extent of an employee's socialization into the organization. Moreover, PU has direct and indirect effects on socialization. Tests on gender and age differences were conducted. The invariance analysis of the theory model showed that both males and females demonstrated the same patterns in performing technology acceptance factors and socialization, whereas different age groups demonstrated significantly different paths. The direct effect of PU was not significant for the newcomers aged over 35.     

Trends in multiculturalism in health care

Materiel managers are faced with a shrinking world and changing work environment. The needs and expectations of the customer have shifted because of the increasing number of multicultural groups. These groups will continue to assert their right to culturally sensitive care. Materiel managers also need to learn to support and enhance the skills of a multicultural work force. One important tool for change will be technology. However, technology that brings the world closer together also creates new challenges for managers, who will have to deal with multicultural colleagues, buyers, sellers, and manufacturers of goods and services.

Statutory union recognition in the UK: a work in progress

The 1999 scheme for statutory union recognition has been criticised for being too complex, and for leaving important matters unclear, for doing too little for workers and unions and for requiring too much from employers. The similarity to the US system has also been criticised. There were fears that attempts to achieve statutory union recognition would redirect the energy of trade unions in the UK to fruitless limbs, forcing unions and employers into antagonistic litigation. Although some of these criticisms are tenable, legislation seldom satisfies all parties affected by it, and all new legislation is haunted by the spectre of unintended consequences. Nevertheless, the system of statutory union recognition adopted in the UK strikes a reasonable balance between the interests of the rival parties and appears to function efficiently and, for the most part, fairly.     

Performance and reward practices in foreign multinationals in the UK

This article examines variability in pay and performance management systems (PPMS) across foreign multinational companies (MNCs) in the UK, using a representative survey. It examines factors shaping PPMS for two groups, managers and the largest occupational group (LOG). It finds that US MNCs tend to have more PPMS practices in combination than do non‐US firms, but that for individual items nationality has relatively low influence, particularly for LOG. Other key factors in PPMS vary by employee group: for managers, international HR structural mechanisms for networking, organisational learning and the transmission of a global HR philosophy are important. For LOG, collective bargaining coverage is crucial. The article discusses the implications of the findings for ‘contingency’ approaches to HR ‘architecture’.     

Straight-line models in star-shaped mixtures

Normal-theory inferences are validated in part for straight-line models having star-contoured errors. Adverse effects for the intercept include inconsistent estimation and disturbances in levels of the standard tests. Tests for slope remain exact in level; they are unbiased; and their power through mixing typically dominates the standard Gaussian case. Bounds on level, and envelopes for power curves, are given for certain ensembles and mixtures of distributions, and these are evaluated numerically for selected cases. Effects of mixtures on model diagnostics are examined further.     

Entrepreneurial Brokers in Disaster Response Network in Typhoon Haiyan in the Philippines

Abstract

Entrepreneurial brokers play a major role in governance networks in a disaster response setting. By identifying patterns of interactions between members in a network of embedded ties, we can explore the strategic use of brokers to mobilize an effective coordination system in the case of the 2013 Philippines disaster. Empirical data were gathered from reported interactions beginning 2 days after Typhoon Haiyan for the following 4 weeks. This paper concludes with practical-based recommendations for international and local agencies to enhance their organizational competencies to serve as entrepreneurial brokers in emergency management.     

Covariance functions that are stationary or nonstationary in space and stationary in time

There is a great demand for statistical modelling of phenomena that evolve in both space and time, and thus, there is a growing literature on covariance function models for spatio-temporal processes. Although several nonseparable space–time covariance models are available in the literature, very few of them can be used for spatially anisotropic data. In this paper, we propose a new class of stationary nonseparable covariance functions that can be used for both geometrically and zonally anistropic data. In addition, we show some desirable mathematical features of this class. Another important aspect, only partially covered by the literature, is that of spatial nonstationarity. We show a very simple criteria allowing for the construction of space–time covariance functions that are nonseparable, nonstationary in space and stationary in time. Part of the theoretical results proposed in the paper will then be used for the analysis of Irish wind speed data as in HASLETT and RAFTERY ( Applied Statistics , 38 , 1989, 1).
