In this paper, I study the causal effects of part‐time work on current and future wages. To estimate these effects, I use a random effects model with a wage equation capturing the employment history and a dynamic multinomial probit component for the choice of employment status. Exclusion restrictions from the institutional context are exploited to support identification. The results suggest that working part‐time with few hours has a large causal effect on current wages, but more extensive part‐time work does not reduce current wages. However, both types of part‐time work lead to negative long‐term wage effects.  相似文献

This exploratory study analyzes the careers of 307 supply chain executives (SCEs). Motivated by career theory, our findings create new knowledge about the educational backgrounds and career paths that lead to SCE positions. Based on an optimal matching analysis, we are able to distinguish among six career patterns for SCEs. They differ in terms of the individuals’ previous professional experience, educational background, and the time they needed to arrive in an executive position. By characterizing the backgrounds and career paths of SCEs, we show that supply chain management (SCM) is truly a cross‐functional profession. Our findings suggest that previous staff responsibility appears to be a more important hiring criterion than extensive SCM experience. While 56% of the executives had prior staff responsibility, only 12% of the cumulated careers were actually spent inside the SCM function.  相似文献

There is a need to better understand the interests of actors in the planning and management of major events. The diversity of actor perspectives about an event creates a wicked problem set that event organisers and public officials find difficult to understand, let alone address. This paper focuses on problem identification as one stage in the event planning and management process. It explores how problem structuring can contribute to more effective planning and management of actors' interests. The value of Q methodology is explored through a case study of the Australian World Rally Championship. Four perspectives are identified in the problem structuring process: the Skeptics, the Materialists, the Middle-grounders and the Supporters. The findings demonstrate that Q methodology is effective in identifying the depth and breadth of different problem perspectives, providing insights into the importance of different perspectives, and can be used reflexively to anticipate and manage potential conflict.  相似文献

Due to the advantages of being able to function under harsh environmental conditions and serving as a distributed condition information source in a networked monitoring system, the fibre Bragg grating (FBG) sensor network has attracted considerable attention for equipment online condition monitoring. To provide an overall conditional view of the mechanical equipment operation, a networked service-oriented condition monitoring framework based on FBG sensing is proposed, together with an intelligent matching method for supporting monitoring service management. In the novel framework, three classes of progressive service matching approaches, including service-chain knowledge database service matching, multi-objective constrained service matching and workflow-driven human-interactive service matching, are developed and integrated with an enhanced particle swarm optimisation (PSO) algorithm as well as a workflow-driven mechanism. Moreover, the manufacturing domain ontology, FBG sensor network structure and monitoring object are considered to facilitate the automatic matching of condition monitoring services to overcome the limitations of traditional service processing methods. The experimental results demonstrate that FBG monitoring services can be selected intelligently, and the developed condition monitoring system can be re-built rapidly as new equipment joins the framework. The effectiveness of the service matching method is also verified by implementing a prototype system together with its performance analysis.  相似文献

For selected regions of five EU Member States (Bulgaria, Hungary, Poland, Romania and Slovenia), this paper examines the determinants of the commercialisation of (semi)subsistence farms. While subsistence farming has become an important feature of the EU, there is a lack of evidence on its spatial distribution, importance and reasons for persistence. The analysis utilises cross-regional survey data and qualitative interviews. Results suggest the absence of a subsistence poverty trap driven by either farmer perceptions or transactions costs although capital endowment appears to play a significant part. On the other hand the degree of market engagement depends on access costs, which vary with location, households’ productive assets, specialisation, and risk propensity. Implications for land use policy are discussed.  相似文献

Due to a rising pace of knowledge production, reviewing extant knowledge on mature topics has become increasingly challenging. Researchers often need to account for hundreds of references with little guidance on how to proceed. Taking the phenomenon of the country‐of‐origin effect (COE) as an example, this paper proposes a solution to tackle this challenge. By adopting the principles of integrative literature reviews and using online databases, bibliography management software, and literature‐mapping techniques, I organize 355 papers about the COE. As a result, the nomological network of the COE is drawn while establishing links between the phenomenon, its antecedents, and its outcomes. This methodological article contributes to building better literature reviews. Copyright © 2015 ASAC. Published by John Wiley & Sons, Ltd.  相似文献
