Modeling perceived job productivity and its antecedents considering gender as a moderator

This study proposes a conceptual model for examining the formation of perceived job productivity and its antecedents. In the model, leader–member exchange and job satisfaction both directly and indirectly influence perceived job productivity, with the latter effect occurring through the mediation of organizational commitment. Gender moderates each model path. The moderating effects are simultaneously tested using data from 344 engineering staff of a large Taiwanese high-tech manufacturer. Lastly, the empirical findings and their implications are discussed.     

Evidence-Based Suicide Prevention Screening in Schools

Screening for suicidality, as called for by the President's New Freedom Commission on Mental Health, is a major public health concern. As a place where adolescents spend a considerable amount of their waking hours, school is an important venue for screening adolescents for suicidal behaviors and providing preventive education and risk management. Social workers, as the largest occupational group of mental health professionals in the United States, have a significant role to play in the national strategy to prevent youth suicide, especially at the school level. This article reviews the literature on suicide prevention screening, warning signs, and risk factors to gain a better understanding of evidence-based screening strategies and discuss the implications for school social workers, counselors, and psychologists. It focuses on the identification of research-based information and explication of potential means for guiding preventive screening and clinical practice with suicidal adolescents.     

Case studies of technology roadmapping in mining

Mining is a long established art with legacy processes and institutional structures that face rapidly changing technological environments. The perception is that technology planning and forecasting receives priority attention only as far as they may be linked to making production tonnage in the short term, thus giving the impression that new technology may be introduced without developing a culture and operational requirements that influence successful implementation of new technologies. With depleting ore grades of existing mines, and the prevailing global financial crisis making it prohibitive to develop richer sources, mining is considered to be short-term risk averse and this accentuates a more conservative approach towards technology planning and forecasting. Based on surveys and interviews with practicing miners, this paper discusses three case studies on the practice of technology planning and forecasting in mining firms. It is evident that technology planning and forecasting, and particularly the use of the roadmapping approach, is not a ‘culture’ common to mining firms.     

Measuring performance of two-stage network structures by DEA: A review and future perspective

Data envelopment analysis (DEA) is a method for measuring the efficiency of peer decision making units (DMUs). An important area of development in recent years has been devoted to applications wherein DMUs represent two-stage or network processes. One particular subset of such processes is those in which all the outputs from the first stage are the only inputs to the second stage. The current paper reviews these models and establishes relations among various approaches. We show that all the existing approaches can be categorized as using either Stackelberg (leader-follower), or cooperative game concepts. Future perspectives and challenges are discussed.     

Structures,Challenges, and Successes of Volunteer Programs Co‐managed by Nonprofit and Public Organizations

This article presents a mixed‐methods, multicase study and comparison of volunteer programs in US national parks that have evolved, in response to growth and fiscal pressures, to be co‐managed by national park staff and their nonprofit support partners. Findings detail why and how the expanded partnerships were formed; how they operate; challenges they face; ways in which they adhere to, stretch, and depart from theories of nonprofit management, collaboration, and program institutionalization; and the significant—even exponential—volunteer program growth that resulted in each case. These nonprofit?public volunteer program partnerships—at Acadia, Arches and ­Canyonlands, Cuyahoga Valley, Golden Gate, the National Mall, and Yosemite national park sites—employ many standard forms of interorganizational relations, even though in these cases the nonprofits give money to the government organization instead of the reverse. Their volunteer program and management structures also share similar elements because of coercive, normative, and mimetic pressures. At the same time, each volunteer program partnership is a distinct blend of collaboration and management practices because of the unique natural features, climate, needs, adjacent populations, and personalities of leaders at each site. The cases employ innovative strategies to substantially increase the number of staff who lead volunteer programs. Recommendations are offered for nonprofit management research and practice, and findings are instructive for organizations that utilize volunteers either as a single entity or as part of a collaboration.     

Young Adult Carers: The Impact of Caring on Health and Education

Research has shown that young people who care for parents and relatives (young carers and young adult carers) are at greater risk of mental and emotional difficulties and are more likely to do badly at school or college. To explore the difficulties faced by young adult carers (aged 14–25) in the UK, an online survey was conducted. Almost half (45%) of the 295 respondents reported having a mental health problem. The relationship between the extent of caring and perceived mental health problems and the impact of caring responsibilities on work and education were investigated.
