Interactions between task repetition and psychosocial factors

Psychosocial factors, individual factors, workplace requirements, and workplace organizational factors have all been reported as being associated with the risk of musculoskeletal disorders [11]. Huang, Feuerstein, and Sauter [5] described the various concepts and models proposed to link occupational stress and work-related upper extremity disorders, as well as the difficulty in verifying the suggested linkages. Huang et al. [5] suggested that decomposing a complex model would be an appropriate method to begin the investigations of the proposed models. Task repetition is a workplace requirement that is considered a potential risk factor for cumulative trauma and its relationship to psychosocial factors was investigated. The study found only weak to no statistically significant relationship between task repetition and reported psychosocial factors of job stress in workers in Taiwan.     

Tire aging: a human factors analysis of failure to warn and inform

A scenario of an automotive accident caused by tire failure is given followed by a human factors analysis of the information available to consumers on tire aging. Consumers have not been told that the age of the tire is a safety concern. It is not easy to decode the date of manufacture on tires. More publicity and prominent warnings are needed to communicate the dangers of older tires. Also, better ways to present the date of manufacture so that consumers can more easily and accurately assess tire age are needed.     

Empirical issues in lifetime poverty measurement

Recently there has been increased interest in developing methods for measuring poverty in a way that takes into account the lifetime experience of individuals. We analyze some specific proposals that take the so-called spells approach and consider how they differ in the manner in which they address issues of lifetime poverty, most notably the measurement of chronic poverty. Comparing these specific measures by applying them to a US panel data set, we provide important insights for further research in conceptualizing and measuring lifetime poverty.     

A noncooperative marriage model with remarriage

I propose a noncooperative marriage model that explicitly accommodates the possibility of endogenous exit and remarriage, and where marriages are of variable quality. The fundamental innovation is that the remarriage decision is infinitely repeated and the problem is fully stationary, reflecting the contemporary reality in marriage markets. I show that cooperative behavior within marriage is possible in subgame perfect equilibrium both in a setting where marriage quality is independently drawn and in a setting with persistent spouse-specific characteristics and an evolving marriage market quality. I show that spouses engage in cooperative behavior most easily when they have intermediate patience levels, which is a non-standard but intuitive game theoretic result in this setting. This model also contributes to the game theory literature by proposing another avenue for sustained cooperation in a repeated prisoner’s dilemma with endogenous exit: randomness in payoff streams.     

Functional disability among chronic pain patients receiving long-term opioid treatment

This study of 2,163 adult chronic, non-cancer-pain, long-term opioid therapy patients examines the relationship of depression to functional disability by measuring average pain interference, activity limitation days, and employment status. Those with more depression symptoms compared to those with fewer were more likely to have worse disability on all 3 measures (average pain interference score >5, OR = 5.36, p < .0001; activity limitation days ≥ 30, OR = 4.05, p < .0001; unemployed due to health reasons, OR = 4.06, p < .0001). Depression might play a crucial role in the lives of these patients; identifying and treating depression symptoms in chronic pain patients should be a priority.     

The relationship between ethnicity and fertility in New Zealand

While there is a global shift towards smaller families, some groups maintain relatively high fertility rates. The 2013 New Zealand census data were used to investigate the nature of fertility between ethnicities in New Zealand. The NZ Deprivation Index 2013 was used as a measure of socioeconomic status to determine the relationships with fertility. The results mirror research outside of New Zealand in that socioeconomic status is inversely correlated to fertility. Using crude average fertility rates, sole-ethnicity Pasifika and Māori ethnic groups still have substantially higher fertility than sole-ethnicity Europeans and Asians ethnic groups, even when simultaneously accounting for age, socioeconomic status, education, and religious affiliation. Christians have more children than individuals reportedly without any religion, and fertility rates drop on average for mothers who have higher formal qualifications. Our findings suggest that cultural, or other ethnic-specific factors differentially affect fertility for Māori, Pasifika, New Zealand European, and Asians as aggregated ethnic categories, respectively.     

Im/mobile highly skilled migrants in Qatar*

Most studies on the mobility of highly skilled migrants have been examined with a framework of global talent mobility and under conditions of neoliberal governance and economic globalization. In this study we challenge the notion of the hypermobile knowledge worker. Utilizing mixed methods, we examine the factors that attracted highly skilled migrants to Qatar and the conditions under which they might leave in the future. Rather than finding a group of footloose migrants attracted primarily to high-wage jobs, a lack of taxation or amenities, and with multiple alternative locations of residence, we find that highly skilled migrants exist on a spectrum of immobility. More significantly, this immobility depends on the migrant’s region of origin. For Asian and Western migrants immobility is attributed to the Kafala system or employer sponsorship, which hinders occupational and spatial mobility and ties workers to their sponsors. Arab highly skilled migrants are especially affected by lack of security and stability in their home countries, which makes these workers involuntarily immobile. The former group seem to be willing to accept a reduced level of agency and mobility for high income, whereas for the latter security and stability are more fundamental to their decision to come to Qatar.     

Making sense of pragmatic and charismatic leadership stories: Effects on vision formation

For some time, it has been argued that stories articulated by leaders are an important vehicle for exercising influence, but stories of leadership might also serve as a means for developing leadership potential. One critical activity involved in leadership is vision formation, which involves constructing and communicating a future state that guides followers in “making sense” of complex organizational events. Like leader visions, analyzing stories also, by nature, evokes sensemaking processes. As a result, analyzing stories of leadership may provide a natural means for practicing the art of sensemaking. In the present investigation, undergraduates were asked to read six short stories about incidents of either pragmatic or charismatic leadership in business settings. After reading each story, questions were asked to encourage sensemaking of story events, causes, and emotions. Participants were subsequently asked to formulate visions for leading a secondary school –– a transfer task. It was found that stronger visions were produced when participants were asked to analyze both story events and the causes of these events. The implications of these findings for the use of leadership stories in leader development initiatives are discussed.     

Operational Risk in Financial Services: A Review and New Research Opportunities

We present a framework to describe and analyze operational risk in financial services from an operations management perspective, focusing in particular on process design, process management, and human behavior aspects. The financial services industry differs from other service industries in ways that affect the nature of the operational risks it is subject to. In recent decades, many books and papers have focused on operational risk in financial services; however, this literature has focused mainly on the conceptual and statistical aspects of operational risk management and not on its operational aspects. Operational risk in financial services has not received much attention from the operations management community. The framework presented here is based on the premise that operational risk in financial services can reap significant benefits from research done in the theory and practice of operations management in manufacturing industries as well as in other services industries. The objective of this study is to propose particular challenges and questions raised in the practice of operational risk management that may stimulate future research in this particular area of operations management.     

Cognitive skills and leadership performance: The nine critical skills

Over the years, a growing body of evidence indicates that certain cognitive skills are a critical determinant of leader performance. In the present effort we show that application of these skills is typically founded in case-based knowledge. Subsequently, we identify nine key skills people in leadership positions employ when working with case-based knowledge to address leadership problems: 1) problem definition, 2) cause/goal analysis, 3) constraint analysis, 4) planning, 5) forecasting, 6) creative thinking, 7) idea evaluation, 8) wisdom, and 9) sensemaking/visioning. Individual and situational contingencies shaping effective application of these thinking skills is discussed. In addition, the implications of findings bearing on leader thinking skills for leader assessment and leader development are considered.
