This paper uses a Swedish micro-dataset containing 2,696,909 hires during the period 2002–2006 to assess the impact of job-related mobility on plant-level performance. The analysis classifies new recruits according to their work experience and level of formal qualification, as well as by the region of origin and of destination. New hires are divided into graduates and experienced workers and between high- and low-educated. The results point towards the importance of acknowledging both the experience and the skills of new recruits. The greatest benefits are related to hiring new workers from outside the region where the plant is located. The analysis also stresses the importance of geography, with plants in metropolitan regions gaining the most from labour mobility, while the benefits of mobility for plants in smaller, more peripheral regions are more diverse and dependent on both the type and origin of new workers. 相似文献

The proposed work is incorporated into the research theme concerning the maintenance and inspection of sensitive facilities in production systems. It is essential to promote the methodological deployment of inspection techniques to ensure the good functioning of services provided by complex production systems as well as their different components. We use a risk-based inspection methodology offering an organized analysis with knowledge sharing for collaborative possibilities in a multidisciplinary context and it consists of the following steps: data acquisition and information collection, failure analysis (probability and consequences), risk assessment, inspection plan, mitigation and revaluation. The application of this methodology can improve the maintenance management strategies of industrial companies. The inspection department is able to forecast its potential failure, root causes and impacts on the safe operation of the considered production system, based on a reliable inventory of existing situations and review options for continuous improvement in maintenance management. In particular, we addressed the application of a Risk-Based Inspection (RBI) methodology in the French petroleum company with operations on the west coast of central and southern Africa. The incorporation of expert knowledge into risk assessment is helping to find the best preventive plan for pipeline inspection in the case study. 相似文献

本文运用地理学和物理学的规律进行论证,认为楚义芳同志在《地理学的逻辑方法与基本法则》一文中提出的“地理学公理”不能成立。并在此基础上进一步阐明一个公理体系不适合于地理学,而经验假设则是绝对必要的。 相似文献

In architourism, tourists are attracted to places because of iconic buildings. Increasingly, non-iconic buildings of vernacular architectural styles are also appreciated by visitors as a way to authentically experience a place. This paper explores architourism in Malaysia and Singapore through the lens of historic boutique hotels. Geographical discourses in and methodologies of architectural geography are used to interrogate what these hotels mean for guests and hoteliers, and the effects on them too. Empirical findings deepen understanding of architourism through examining how ‘producers’ create culturally authentic environments in boutique hotels, and how ‘consumers’ utilise hotels to experience local cultures. The dual focus on production and consumption is in-line with critical architectural geography’s insistence on exploring the rhetoric of building design as well as the realities of their everyday uses and users. 相似文献

This paper explores the phenomenon of local climate perception and the extent to which public perceptions match climate conditions as recorded in instrumental climate data. We further examine whether perceptions of changes in local climates are influenced by prior beliefs about global warming, through the process of motivated reasoning. Using national survey data collected in the United States in 2011, we find that subjective experiences of seasonal average temperature and precipitation during the previous winter and summer were related to recorded conditions during each season. Beliefs about global warming also had significant effects on subjective experiences with above-normal temperatures, particularly among those who believed that global warming is not happening. When asked about the summer of 2010, those who believed that global warming is not happening were significantly less likely to report that they had experienced a warmer-than-normal summer, even when controlling for demographics and local climate conditions. These results suggest that the subjective experience of local climate change is dependent not only on external climate conditions, but also on individual beliefs, with perceptions apparently biased by prior beliefs about global warming. 相似文献
