Using insights from a case study on the allocation of labor in subsistence households in Mozambique, this study develops a conceptual framework for examining linkages between time poverty and farm production. An unexpected event such as a health crisis increases the demand for labor provided by women, thus making them more time poor. The model and numerical simulations show that a deterioration in a woman's time constraint will have an adverse effect on agricultural output of the household. This occurs because most women respond to an increase in household work by reducing their work hours on the farm and by reducing their leisure time. The latter outcome is expected to have a negative effect on women's physical and mental health, which will then cause a decline in their productivity on the farm.  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

In this paper, an analytical approximation formula for pricing European options is obtained under a newly proposed hybrid model with the volatility of volatility in the Heston model following a Markov chain, the adoption of which is motivated by the empirical evidence of the existence of regime-switching in real markets. We first derive the coupled PDE (partial differential equation) system that governs the European option price, which is solved with the perturbation method. It should be noted that the newly derived formula is fast and easy to implement with only normal distribution function involved, and numerical experiments confirm that our formula could provide quite accurate option prices, especially for relatively short-tenor ones. Finally, empirical studies are carried out to show the superiority of our model based on S&P 500 returns and options with the time to expiry less than one month.  相似文献

As talent management evolves from intuitive to evidence‐based decision‐making, the role of electronic Human Resource Management (eHRM) to gather, distribute, and analyze data becomes more critical. However, surprisingly few academic studies investigate the role of technology in talent management. Drawing on a qualitative case study of talent management in a large professional services firm, this paper critically examines how eHRM information technologies are framed as useful within talent identification discourses. The findings reveal two distinct but interrelated sets of processes employed to identify talent and suggest that the perceived usefulness and centrality of eHRM are influenced by how stakeholders shape their understanding of effective talent management.

It is proved that teachers' politeness behavior can highly motivate students' learning impulse and improve teaching process. Politeness phenomenon in classroom has been broadly discussed and studied; however, there are still no systematic politeness principles that can be reasonably applied into the teaching process. On the basis of the politeness theories and a case study, this paper tries to seek a more reasonable and more efficient politeness principle in EFL classroom.  相似文献

This paper reviews the theoretical foundations of the equity based foreign market entry (FME) decisions literature. We analyse 1055 academic FME papers published over four decades (1970–2013). We identify and analyse the theories that informed and guided FME research over time. Our review indicates that scholars have recently started to challenge some of the core assumptions of established theories, draw on and integrate insights from multiple theoretical perspectives which, in turn, generated a multiplicity of approaches for studying FME decisions and their performance outcomes. The paper discusses the explanatory power of the different theories, assesses the relevance of the different theoretical perspectives to our understanding of current FME phenomena and recommends directions for further research.  相似文献

This study evaluates bibliometric studies in tourism, depicts emerging themes, and offers critical discussions for theory development and future research. To achieve this aim, 190 papers with bibliometric analyses from leading hospitality and tourism journals were selected and critically analyzed. The research findings reveal that bibliometric articles published in these journals significantly increased after 2008. However, systematic review studies emerged as the major group, and relatively few studies utilized evaluative bibliometric and relational bibliometric studies. Study results suggest that paucity still exists, particularly in relational bibliometric studies in tourism. This is one of the first studies in this area that offers critical discussions and suggestions related to theory development and future research in this research vein.  相似文献

A collaborative project of several Quebec universities, this study investigates nontraditional student withdrawal from undergraduate accounting programmes. A nontraditional student is older than 24, or is a commuter or a part-time student, or combines some of these characteristics. Univariate and multivariate analyses of student dropout factors were performed. A logistic regression for full-time students indicates several significant determinants of student withdrawal: returning to school after working for some time, enrolment in a non-first choice programme, dissatisfaction with programme choice and courses, and low grade point average (GPA). For part-time students, low GPA is the main explanatory factor for student withdrawal. Other factors appear to be instrumental in withdrawal decisions, such as management of external resources (time and family responsibilities) for women. The results suggest that students would benefit from university support services to acquire learning strategies that improve perseverance. Lastly, in-class learning activities that help bolster grades could decrease student withdrawal rates.  相似文献

Social networks are becoming increasingly important for consumers, especially in the context of sport, where the service experience is highly intense. Few studies have combined subjective event performance variables and social network variables to analyze social network content sharing by sports practitioners. This article investigates the use of social networks in relation to sporting events. An empirical study examined the role of social network variables and sporting event performance variables in social media use. The sample consisted of 410 triathletes (72.2% male) aged between 18 and 66 years (mean 37.03 ± 8.62). Four analyses were performed using fuzzy‐set qualitative comparative analysis to examine the causes of sharing comments through social media, sharing photos and videos on social media, participant satisfaction, and word‐of‐mouth (WOM). The event's general image was a necessary condition in all cases. The combination of participants’ satisfaction and positive event image and the combination of social network use and positive event image lead to social network content sharing by athletes. The combination of positive event image and participant satisfaction leads to a positive WOM.  相似文献

This study explores how firms can realise ‘continuous’ supply chain process improvement. Specifically, this study proposes the success factors of routinised activities (also called ‘repeated activities’) in the supply chain process improvement. Eight Japanese manufacturers are selected for the case studies. These firms are selected based on their supply chain process operation capabilities. From the case studies, we find that the planning of supply chain process improvement depends on the existing stage of the firm’s Supply Chain Management reform. In addition, even firms with high scores for supply chain process operation capabilities do not have supply chain performance systems. Furthermore, quite surprisingly, many Japanese manufacturers tend to improve their supply chain processes in the absence of such systems.  相似文献
