水泥稳定碎石的作用原理及在公路施工中的应用

水泥稳定碎石作为路面基层,具有早期强度高,雨季对施工影响相对较小,施工机械化程度较高等特点,这些都有利于保证进度和质量,因此被越来越广泛地应用到市政道路工程中去。为此,本文针对城市道路半刚性基层采用水泥稳定碎石的技术研究进行简要分析,以供参考。     

The relationship between leader-member relations,job satisfaction and organizational commitment in international tourist hotels in Taiwan

The tourism industry is an indicator of the degree of internationalization and modernization of a country; and hotels are a key part in the tourism industry. According to studies on foreign tourists to Taiwan, expenses for international hotels make up the major portion of the tourists' total costs. Hence, international hotels play a significant role in the industry. The population for this study is 60 international hotels approved by the Taiwan Tourism Bureau. The sample is formed by 24 of these hotels. A questionnaire survey was conducted and 303 valid replies were received. The research analyzes cause and effect relationships among leader-member relations, as well as organizational commitment and job satisfaction utilizing structural equation modeling. The results show that job satisfaction is the mediating variable between organization commitment and leader-member relations.     

Job stress,coping strategies,and burnout among hotel industry supervisors in Taiwan

The complex and changing environment of the hospitality industry presents a never ending array of stimuli, pressures and demands which can become sources of stress for hotel supervisors. A focus on the identification of current and potential stressors in organizations, and the development of strategies which individuals and management may use to manage and reduce stress effectively, is imperative. This study is to investigate the perceived level of stress of hotel supervisors, to establish frequency of the use of various coping strategies, and to determine the burnout rate. This study also empirically examines the relationships among stress, coping strategies, and job burnout. A convenient sample of hotel supervisors of large hotels in Taiwan was selected. The return of 298 questionnaires represented 74.5% of the total supervisors surveyed. The study findings suggest that the major job stress of hotel supervisors originates from task characteristic and workload. Moreover, a direct action coping strategy may allow one to perceive the situations as opportunities and may, in turn, contribute to reduce job stress. Furthermore, hotel supervisors experience a lower level of burnout if they apply more direct action strategies in coping with the pressures of their job. The results of this study can be used as part of guidelines including what should be considered to reduce job stress and burnout in the work environment.

Selecting people based on person‐organisation fit: Implications for intrateam trust and team performance

Teamwork is widely adopted in organisations. Although much evidence indicates that using person‐organisation (P‐O) fit as a selection criterion benefits individual employees, little is known about how this practice influences team functioning. Drawing on the input‐mediator‐outcome model and the research on value congruence, this study built and tested a model that links P‐O fit in recruitment to work teams' performance. Based on data collected from team members, team leaders, human resources managers, and chief executive officers in 96 firms, we found that P‐O fit in recruitment had a positive relationship with team performance and that intrateam trust mediated the relationship between P‐O fit in recruitment and team performance. Further, this mediated relationship existed only when the organisation had a weak, rather than strong, respect‐for‐people culture. This study contributes to the P‐O fit and team literature and has practical implications for human resources practices and team management.     

面向大数据时代的城市规划研究响应与应对方略

随着智慧城市建设的推进,城市大数据时代已经到来,大规模的全样本数据呈现出新的研究价值。利用大数据感知社会动态、辅助决策实施;将大数据应用于城市规划,使宏观政策对微观个体的影响有了量化评价手段和具体反馈渠道。大数据时代给城市规划的范式研究和实践研究都带来了强烈的冲击,结合城市大数据现状,从城市规划的研究范式演进和与大数据的实践融合两个方面展开讨论,研究范式演进包含从理性主义到新理性主义、从以地生财到以人为本和从自上而下到自下而上三个层面;与大数据的规划实践融合主要体现在城市功能区识别、城市空间行为研究和城市交通研究三大领域。最后,针对大数据在城市规划领域应用中出现的问题,提出响应策略与应对方略,对未来城市规划发展提供一些参考。     

Social networks,mass media and public opinions

Our opinions and ideas are shaped by what our friends said and what we read or watched on mass media. In this paper, we propose a concise and analyzable model to study the effects of mass media modeled as an applied external field, and social networks on public opinions based on the multi-state voter model, and a tuned parameter can control the relative intensity of the effects of mass media and social networks. We consider a generalized scenario where there exist committed or stubborn agents in the networks whose opinions are not affected by their friends or mass media. We find that the fraction of each opinion will converge to a value which only relates to the fractions and degrees of stubborn agents, and the relative intensity between media and network effects. The final agents with media opinion, except the stubborn agents, also include the increment produced by the internal impact of social networks and that caused by the external impact of media. Interestingly the second increment is composed of two parts, one is from the media effect when there are no interactions between agents and the other is from the influence of media on agent opinions caused by social network structure. That is the interactions among agents within social networks can amplify media influence. Finally we also discuss several extensions to the dynamics model which consider more realistic scenarios.
