平煤十三矿水文地质特征及充水因素分析

本文通过对平煤十三矿含、隔水层及断层带水文地质特征的分析,对现开采二1煤层有影响的主要为地表汝河水、第四系含水层水、二1煤层顶板砂岩水、石炭系灰岩溶岩水和寒武系灰岩水。地表汝河水、第四系含水层水和二1煤顶板砂岩水对煤层的开采影响较小。受采掘活动的影响,煤层底板下的石炭系灰岩溶岩水对矿井安全生产威胁最大,在遇断层时,寒武系灰岩水可能会通过断层带参与补给,要特别注意预防底板灰岩水突入矿井。

Perspectives on line managers in human resource management: Hilton International's UK hotels

Although contextual factors act to encourage the devolvement of human resource management to line managers, recent research indicates that there is substantial potential for human resource specialists and line managers to share more effectively responsibility for their organization's human resource activities in business partnerships. The foundation for this is arguably commonality in opinions on the principles and practices of human resource activities. However, line managers and human resource specialists often have dissonant opinions on human resource management.

This paper explores line manager and human resource specialists' perspectives on line manager involvement in human resource management, theoretically and empirically. The primary work comprises a survey of the views of line managers and human resource specialists on devolving a range of human resource activities to line managers in a case organization, Hilton International's UK hotels. Differences between line managers' and human resource specialists' perspectives are found in five aspects: understanding and ownership of the company's service and HR strategy; line manager involvement in and rankings of HR activities; HR specialists' support of line managers; barriers to line managers' involvement in HR activities; and the competence of line managers in HR activities. Importantly, it is found that where there are divergent views across line managers and their HR specialist in their hotel there is poor hotel business performance and, conversely, convergent views are evident in the effectively performing hotels. These findings may have resonance for other organizations in devolving human resource management to the line and developing human resource business partnerships for business performance. It is proposed that three types of line manager buy-in are central to their active involvement in HR, namely: conceptual understanding of the rationale for their involvement; implementation effectiveness through HR role clarity and capability; and affective commitment in believing in the value of their involvement in HR.

CONCEPTS OF POVERTY AND THE POVERTY LINE

Abstract. Various approaches adopted in developed economies to distinguishing between the poor and non-poor—to setting a poverty line—are reviewed. These include the budget standard, food ratio, 'official', subjective and relative poverty line methods, as well as the analysis of indicators of deprivation. There has been significant progress in recent years in the degree of sophistication involved, and a movement away from approaches with a quasi-absolute background. However, all the methods face formidable problems at conceptual and empirical levels, and no single approach is likely to dominate.

Line and HR executives' perceptions of HR effectiveness in firms in the People's Republic of China

This paper examines the differences in perceptions of the importance and effectiveness of human resources (HR) practices in firms operating in the People's Republic of China. The major finding is that while there are no significant differences between HR and line executives' perceptions of the importance of each functional area in human resource management (HRM), there are significant differences between line and HR executives' perceptions of the effectiveness of these areas. Line and HR executives both view the issue of securing, developing and maintaining human resources as a critical issue for the execution of daily operations and long-term strategic plans. However, line executives perceive HR performance effectiveness as significantly lower in these functional areas than HR executives do. Therefore, HR departments are not meeting the performance expectations of line executives. There are three possible reasons for the poor performance of HR departments. First, government intervention may limit HR departments' ability to act strategically. Second, HR departments may not have enough power to act strategically. Third, HR departments may have few capabilities to respond to line executives' demands.
