A graduates ’ satisfaction index for the evaluation of the university overall quality

In the higher educational setting, students provide a relevant contribution to the quality of educational services. In such a context, the measurement of the perceived quality and related satisfaction for the university experience are of primary interest to evaluate the efficiency and efficacy of the learning processes. In this contribution, we aim at assessing the overall quality of the graduates’ university experience in terms of internal and external efficacy by applying the ECSI (European Customer Satisfaction Index) methodology, based on structural equation models and primarily developed in the context of customer satisfaction. For this aim, we propose a modified ECSI model tailored for the higher educational setting, explicitly taking into account the differences among groups of degree program. The study is carried out on data collected by the AlmaLaurea surveys at the University of Florence (Italy) in the period 2014–2017 and concerns a sample of more than 2,000 graduates. We find out eight latent variables that contribute to define the overall quality of university experience. These variables are differently affected by the type of degree program, with the highest levels of external efficacy observed for degree programs belonging to the educational, health, and engineering groups. It also turns out that interventions on the internal efficacy (i.e., quality of hardware and quality of humanware) have a direct positive effect on the university (i.e., loyalty) and an indirect positive effect on the society (i.e., external efficacy).     

阿仑磷酸钠片联合唑来膦酸注射液治疗骨质疏松症患者的药物经济学评价

目的探讨阿仑磷酸钠片联合唑来膦酸注射液治疗骨质疏松症的成本-效果。方法选取2016年12月至2018年2月于阜新市中医医院骨伤科治疗的138例骨质疏松症患者作为研究对象,按照随机数字表法分为对照组和观察组,每组69例。对照组给予阿仑磷酸钠片治疗,观察组在对照组治疗基础上采用唑来膦酸注射液治疗,比较两组患者治疗效果,并进行成本-效果分析。结果观察组治疗有效率为97.10%,显著高于对照组的75.36%,差异有统计学意义(P<0.05)。治疗后,与对照组比较,观察组患者腰椎骨、股骨颈和Ward’s三角区骨密度水平显著提高(P<0.05),血清Ca2+、骨特异性碱性磷酸酶(ALP)、降钙素(HCT)水平显著提高(P<0.05),成本-效果比提高(P<0.05),不良反应发生率降低(P<0.05)。结论阿仑磷酸钠片联合唑来膦酸注射液治疗可明显提高骨质疏松症患者疗效,调节骨密度,有助于骨代谢指标恢复,但其成本也较高。     

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 group efficacy mediates the relationship between group affect and identification

This study examines the mediating role of group efficacy on the relationship between group affect and group identification by integrating the collective cognition process. Using a sample of forty-seven work groups in Study 1, the results show that group efficacy fully mediates the relationship between positive and negative group affect and group identification. Study 2 applies a two-wave panel design to verify the impact of group efficacy on group identification. The results of Study 2 indicate that group efficacy relates positively to the development of group identification. The implications for theory and practice are discussed.     

The relationship between high performance work systems and employee proactive behaviour: role breadth self‐efficacy and flexible role orientation as mediating mechanisms

Drawing on the contextual perspective, this study provides novel empirical evidence on how the organisational context (specifically, the firm's human resource strategy) has an effect on employee proactivity. We use matched data from managers and employees in 102 Spanish professional service firms to examine how high performance work systems contribute to enhance employee proactive behaviours through two motivational variables: role breadth self‐efficacy and flexible role orientation. Results of a multilevel study demonstrate that role breadth self‐efficacy mediates between HPWS and employee proactivity, but flexible role orientation does not mediate this relationship.     

Process innovation capability and subsequent collaborative team performance in travel planning: a knowledge exchange platform perspective

Purpose: Backpacker tourism is flourishing in this century as the high development of Internet technology which enables travellers to search for resources they need easier. The research goal of this study was to exam how virtual skill and collective efficacy affect process innovation capability and subsequent team performance of collaborative design team in a virtual community. Design/methodology/approach: In this study, we formulated the virtual team model from the perspectives of open innovation paradigm and virtual competence, and we collected virtual community participation samples from the online communities. Invitation emails were delivered to numerous trip plan initiators in two well-known online travel communities for filling survey questionnaires for this study. In total, 3000 invitation messages were mailed, of which 373 were returned completed. The model and hypotheses were tested by structural equation modelling. Findings: Virtual competence, including collective efficacy and virtual media skill, is the essential key to facilitate process innovation capability and subsequent team performance success. Besides, knowledge sharing significantly moderates the relationship between process innovation capability and the team performance. Originality/value: Backpackers in the online travel communities have to have not only the willingness to collaborate, but also the abilities of using the correct tool to help with their tasks. When a self-efficacy gets into collective efficacy, it enables the collaborative team to develop with good virtual competencies. Accordingly, trip plan initiator and participants of a virtual team are as expertise contributors between conformity in online communities and online compulsive control tendencies.     

Relationship between positive psychological capital and creative performance

Despite considerable attention to the creative process and its relationship with personal characteristics, there is no published study focused directly on the relationship between the recently recognized core construct of psychological capital (PsyCap) and creative performance. Drawing from a large (N = 899) and heterogeneous sample of working adults, this study investigates PsyCap and its components (i.e., efficacy, hope, optimism, and resilience) as predictors of creative performance. Overall PsyCap predicted creative performance over and above each of the four PsyCap components. Theoretical and practical implications of these findings are considered. Copyright © 2010 ASAC.

国际制裁缘何难以奏效?——“非故意后果”的视角

国际制裁一直面临着有效性不足的困境。既有研究将之归因于制裁有效性发挥的三大必要条件——足够的制裁强度、准确的承受主体和可信的制裁承诺——得不到满足,但忽视了制裁的非故意后果的作用。非故意后果是制约国际制裁有效性的重要因素之一,它削弱了制裁方的意志,却增强了被制裁方的抵抗决心;增加了制裁持续时长和制裁成本,却阻碍了主要制裁目标的实现。在既有研究基础上,作者首先提出了一个探讨制裁的非故意后果的分析框架,其次对非故意后果影响制裁有效性的作用机制进行了分析,最后以联合国为例探讨了制裁方在应对非故意后果问题上的尝试。
