Burnout among university accounting educators in Australia and New Zealand: determinants and implications

Increased teaching workloads combined with pressures to publish in limited outlets has intensified the burnout potential among accounting educators in Australia and New Zealand. However, amongst the few studies on tertiary accounting education, the focus has so far been only on burnout arising from student contact intensity. We broaden this literature by examining how other worklife characteristics contribute to burnout. Based on 158 responses from Australian and New Zealand accounting academics, we find evidence for emotional exhaustion due to high workload. However, professional efficacy continues to remain high. Qualitative responses offer deeper insights on how various burnout factors are interrelated.     

How uncivil customers corrode the relationship between frontline employees and retailers

This study investigates the effects of customers’ uncivil treatments on frontline retail employees’ emotions, deviant behaviors and relationship with the retail organization. Our theoretical model is based on both marketing and personnel management literatures. 415 frontline retailing American employees answered our questionnaire. Employees treated uncivilly by customers feel angry but have to hide their negative emotions, which leads them to emotional exhaustion and deviant behaviors. Paradoxically, employees’ strong commitment to their retailing organization brings about more deviant behaviors. We propose some managerial strategies to cope with uncivil customers, as well as future research on this important and under-researched topic.     

Can information and communication overload influence smartphone app users' social network exhaustion,privacy invasion and discontinuance intention? A cognition-affect-conation approach

Thanks to the expansion of network technologies and the coupling of smartphone hardware, younger generations have unparalleled access to a diverse range of information and interactive communication opportunities. Despite voluminous research on the causes of social network exhaustion and privacy invasion, limited academic attention has been devoted to understanding the driving forces and contributing factors for discontinuing usage of smartphone app. Drawing on the cognition-affect-conation paradigm, the present research proposes a conceptual research model to examine how information overload and communication overload effect social network exhaustion, privacy invasion, and ultimately, smartphone app users' intentions to discontinue usage. The study evaluates data from 442 smartphone app users, employing statistical analyses to demonstrate that both information overload and communication overload significantly impact users' exhaustion and privacy invasion. Additionally, social network exhaustion and privacy invasion are two major predictors of smartphone app discontinuance intention. By identifying the influential factors and causes of younger generations' discontinuous usage intention of smartphone app, this study meets the need for a thorough assessment of the social network exhaustion and privacy invasion phenomena. The findings may potentially enhance comprehension of the discontinuation intention phenomenon in the context of cognitive overload. Furthermore, they may provide novel insights for practitioners regarding effective strategies conducive to managing mobile social network adoption behavior, as well as the preservation of engagement levels among young users in mobile-saturated societies.     

Considering the nuclear option: Hidden benefits and social costs of nuclear power in the U.S. since 1970

Although burning fossil fuels has environmental consequences, many countries have switched away from nuclear power in favor of fossil-fuel fired electricity production after incidents at Three Mile Island, Chernobyl, and Fukushima. This study estimates the substitution between nuclear and fossil-fuel fired electricity generation in the United States. Using an event-study framework, we leverage nuclear plant openings from 1970 to 1995 and forced nuclear plant outages from 1999 to 2014. Plant openings (nuclear outages) reduce (increase) monthly net coal-fired generation by approximately 200 GWh, implying a considerable reduction (increase) in emissions. We find that the substitution between nuclear and coal is not one-to-one, as has been assumed in prior literature. After establishing these stylized facts, we explore the potential underlying forces driving the observed substitution between coal and nuclear.     

Backcasting energy futures using industrial ecology

Backcasting has been widely used for developing energy futures. This paper explores the potential for using industrial ecology to guide the development of energy futures within a backcasting framework. Building on the backcasting work of Robinson [1], a seven step method is presented to embed industrial ecology principles within the development and assessment of future scenarios and transition paths toward them. The approach is applied to the case of backcasting regional energy futures in the Latrobe Valley, near Melbourne, Australia. This region has substantial brown coal deposits which are currently mined and used in coal-fired power stations to generate electricity. Bounded by a sustainability vision for the region in a carbon-constrained world, regional industrial ecologies in 2050 were backcast around three themes: bio-industries and renewables (no coal usage); electricity from coal with carbon capture and storage (low to high coal usage); and coal to products such as hydrogen, ammonia, diesel, methanol, plastics and char (demonstrating medium to high overall coal use relative to current levels). Potential environmental, technological, socio-political and economic impacts of each scenario across various life cycle stages were characterised. Results offer a platform for regional policy development to underpin deliberation on a preferred future by the community, industry and other stakeholders. Industrial ecology principles were found to be useful in backcasting for creatively articulating alternative futures featuring industrial symbiosis. However, enabling the approach to guide implementation of sustainable transition pathways requires further development and would benefit from integration within the Strategic Sustainable Development framework of Robèrt et al. [2].     

Investigating the immediate and long-term effects of job stressors on frontline service employees

Two studies investigate the immediate and long-term effects of job stressors on frontline service employees (FSEs). Using cognitive appraisal theory, we develop and test a conceptual model of two job stressors (crowding and emotional labor) that affect coping strategies and job outcomes. Study 1, which is a field experiment, investigates the immediate effects of crowding in a single firm. Study 2 extends the findings of Study 1 and investigates the long-term effects of emotional labor and crowding on FSEs across multiple firms. The results show that crowding has a negative impact on coping strategies and job-related outcomes. In addition, emotional labor can lead to long-term negative outcomes, such as emotional exhaustion and decreased job retention, for some FSEs. Consequently, service organizations should consider strategies or tactics that prevent high levels of customer crowding and help FSEs deal with emotional labor.     

知识产权法体系重构初探

尽管知识产权法属于民法的一部分,但实际上其理论体系的产生、发展有极大的独立性。由于缺乏历史给养的长期积累和高度抽象的理性思维,再加上国家之间利益争斗因素,现有知识产权法体系还很不完善,其理论基础极为脆弱。本文从辨析知识产权与支配权的关系着手,探索性地提出知识产权的核心权能是“控制性传播权”,从而全面概括著作权、专利权、商标权等知识产权的权利内容,进而以此为基础力图对知识产权法体系加以重构。
