本文应用新制度经济学的研究方法,探讨财政问题对政府主导型制度变迁的影响。战后日本在经济赶超过程中形成的"强政府干预"发展模式越来越不能适应内外环境的变化,改革势在必行。但由于日本的"强政府干预"模式是一个长期形成的稳定且复杂的系统,而政府主导的改革又无异于"自我革命",因而制度变迁是困难的。本文通过对日本上世纪80年代以来政府改革的动因——效果(即"政府、企业、个人"关系变化)的考察,认为财政危机是构成日本制度变迁的"硬约束",财政压力是日本经济高速增长结束后"官主导"模式演化的直接起因。 相似文献

Data were collected from a stratified sample of district nurses in the greater Stockholm area on four occasions during one year using questionnaire techniques (to assess psychosocial working conditions and social networks, and self-reported health sums); as well as physiological measurement techniques. Three groups of district nurses were compared: group A, those working independently in the 'traditional' role but outside primary health care centres; group B, those working independently in the 'traditional' role but in primary health care centres; and group C, those working in the model role as part of primary health care teams. The study focused on the effects of these different work environments on the district nurse's psychological and somatic health, and their physiological state.
The data suggested that district nurses in the primary care teams (group C) had a lower objective work load than those working in the more traditional role. Despite this, they reported a less favourable balance (ratio) of work demands to decision latitude. They reported more 'problems' and 'conflicts' at work than did the other district nurses. However, such 'problems' were diminishing during the study period, which could mean that successive adaptation to the 'new' situation was occurring. The 'conflicts', on the other hand, remained. This may indicate that despite this adaptation, the district nurses in the primary care teams were struggling with their new work roles. It points to the need for organizational support during this important change process. The district nurses in group B (traditional role but in a primary health care centre) had the highest objective work load and showed physiological reactions in terms of elevated plasma cortisol levels in the morning, high systolic blood pressure and sleep disturbances. 相似文献

Casual blood pressure (BP) was recorded in a sample of 217 working adults. A questionnaire was used to obtain subjective reports of job stress. comparisons were made between a group with elevated BP and a normotensive group. The high BP group appeared to perceive more stress. In particular, scores on the role conflict, job versus non-job conflict and type A scales reliably differentiated the groups. In contrast, for the job satisfaction items, no difference between the groups was observed. There appeared to be some association between reported occupational stress and BP level. 相似文献

讨论了垂直于突扩通道主流方向的侧壁射流对壁面压力系数、传热系数及主回流区长度的影响.采用标准κ-ε双方程湍流模型,对侧壁射流突扩通道中的流场进行了数值模拟,计算结果表明,侧壁射流位置越靠近入口,主回流区长度越短,最大压力系数位置前移,其数值增大,局部表面传热系数也增大.根据计算结果,拟合出了当侧壁射流速度与突扩通道入口平均流速之比等于2.0时,主回流区长度与侧壁射流位置的关系式。 相似文献
