Cultural Endorsement of Broad Leadership Prototypes and Wealth as Predictors of Corruption

Corruption is a social ill that involves public officials’ misuse of entrusted power, which is a function of sociocultural factors. Rarely, however, do researchers view corruption as a leadership-related problem. In the current research, we conceptualize corruption as a leadership-related problem, and propose three broad leadership prototypes based on social value orientation theory and research. We seek to examine (1) how cultural endorsement of self-serving, prosocial, and individualistic leadership prototypes is related to corruption at the societal level and (2) how wealth moderates the relationship between cultural endorsement of self-serving leadership and corruption. Using archival data of 53 societies, we found that cultural endorsement of self-serving leadership was positively related to corruption, strengthened by wealth. Cultural endorsement of prosocial leadership and individualistic leadership, however, was not significantly related to corruption, and wealth did not moderate either of the relationships. The implications of these findings for theory and future research are discussed.     

INSTRUCTING OPERATIONS DESIGN: AN EXPERIENTIAL APPROACH

Teaching an operations design course has major pedagogical challenges. (1) The design topics—output, process, facility, and work design—are necessarily taught sequentially, yet the decisions are integrative. (2) Instruction must be generic to service or product producers. (3) Discussing output design is difficult since students typically have had no exposure to the “product language” of engineering graphics. (4) No text is available which examines in sufficient depth all the operations design decisions. (5) Cases necessarily depict historical situations—process technologies and economic data—while operations managers must plan future directions for their productive systems. (6) While the commercial world contains fresh information and data, students are inexperienced in obtaining knowledge from the real world. (7) While the course presents an operations management perspective, students must recognize the information, data, and cooperation necessary from the other functional areas to successfully complete the operations design. To help overcome these seven pedagogical challenges, the students in the undergraduate and graduate operation design courses complete a comprehensive feasibility study for a new product or service and the entire productive system.     

Implicit Valuation of the Near-Miss is Dependent on Outcome Context

Gambling studies have described a “near-miss effect” wherein the experience of almost winning increases gambling persistence. The near-miss has been proposed to inflate the value of preceding actions through its perceptual similarity to wins. We demonstrate here, however, that it acts as a conditioned stimulus to positively or negatively influence valuation, dependent on reward expectation and cognitive engagement. When subjects are asked to choose between two simulated slot machines, near-misses increase valuation of machines with a low payout rate, whereas they decrease valuation of high payout machines. This contextual effect impairs decisions and persists regardless of manipulations to outcome feedback or financial incentive provided for good performance. It is consistent with proposals that near-misses cause frustration when wins are expected, and we propose that it increases choice stochasticity and overrides avoidance of low-valued options. Intriguingly, the near-miss effect disappears when subjects are required to explicitly value machines by placing bets, rather than choosing between them. We propose that this task increases cognitive engagement and recruits participation of brain regions involved in cognitive processing, causing inhibition of otherwise dominant systems of decision-making. Our results reveal that only implicit, rather than explicit strategies of decision-making are affected by near-misses, and that the brain can fluidly shift between these strategies according to task demands.     

Trends in bird species richness,abundance and biomass along a tropical urbanization gradient

Impacts of urbanization on biodiversity are commonly studied using urbanization gradients which provide a space-for-time substitution in estimating consequences of urban expansion. Rates of urbanization and human population growth are high in tropical countries of the developing world, which also hold most of the world’s biodiversity hot-spots, yet few studies have considered biodiversity trends along urban gradients in these regions. Bird communities across a gradient of nine sites in Uganda, from the city centre of Kampala to outlying rural locations, were studied over a six year period. These sites were ordered along an urbanization gradient using Principle Components Analysis based on habitat variables estimated at each site. Bird species richness showed a decrease from rural to urban sites, a trend especially evident in forest birds. There was no clear pattern in total abundance, total biomass or biomass per individual along the gradient. However, this latter result was heavily influenced by a colony of Marabou Storks at one site. When this species was omitted, there was evidence of a positive trend with urbanization, showing that as species richness decreased, the bird community was increasingly dominated by larger species with increasing urbanization, which were mainly scavengers able to exploit human refuse. These results provide further support for the negative impacts of urbanization on species richness, but also demonstrate trends in abundance and biomass are variable across different regions. In particular, the increasing dominance of larger species in urban areas may be relevant to certain geographic and/or socioeconomic contexts.     

Mental illness etiology beliefs among African American men with serious mental illness and their social support networks

Semi-structured qualitative interviews were conducted with 26 African American men with serious mental illness who were consumers of community mental health services and 26 members of their social support networks. All participants were asked what they believed had caused the consumers’ mental illness. Consumer participants most commonly identified chronic life stressors as a causal factor, while social supports most often identified intrinsic factors such as genetics or biology as causes of mental illness. Some support participants believed that unintentional drug use had precipitated the onset of mental illness or had no causal theories. The fact that some support participants could not identify a causal explanation may indicate failure on the part of mental health care systems to engage with consumers’ social support networks and provide education about mental illness and its causes. The implications of etiology beliefs on mental health service utilization are discussed.     

Residential Remittances and Food Security in the Upper West Region of Ghana

In recent years, out migration from the Upper West Region to the southern belt of Ghana for farming has become commonplace. The natural question that has arisen is: what is the potential impact of remittances from this migration pattern on food security in the region? Using multivariate ordered logistic regression this study assesses the linkage between remittances and household food security (derived using the HFIAS) among urban and rural households (n=1,438) in the region. The findings show that urban remittance‐receiving households and rural remittance and non‐remittance receiving households were more likely (OR=2.44, p<0.05; OR=2.46, p<0.001; and OR=1.49, p<0.1, respectively) to report being more severely food‐insecure than urban non‐remittance receiving households. The findings demonstrate that household strategies such as migration and remittances on their own are not sufficient to ameliorate the precarious food insecurity situation of the region. The study calls for development of alternative livelihoods in the region.     

A cross-border perspective on migration: beyond the assimilation/transnationalism debate

The transnational perspective emerged in the early 1990s as an alternative to assimilation theory, gaining instant and wide influence. But curiously, the intellectual confrontation between these two perspectives was averted, as scholars concluded that persistent homeland engagement was fully compatible with hostland integration. This paper seeks to pick up that challenge. I demonstrate how a cross-border perspective, encompassing places of origin and destination and the flows of people, ideas, and resources between them, highlights the ways in which population movements across state borders create tensions on both receiving and sending sides. In the process, I will show how looking across borders paradoxically highlights the centrality of the territorial boundary, as it simultaneously underscores the importance of dissimilation – the social and political separation of immigrants from the people they have left behind – yet also the ways in which non-citizen status and foreign origins simultaneously hamper immigrants’ ability to gain acceptance in receiving states while furnishing sending states with opportunities to reconnect with nationals abroad.     

How do people differentiate between jobs: and how do they define a good job?

Employed individuals from a range of jobs (n=18) were interviewed using a repertory grid technique, to explore the criteria they used to distinguish between different jobs. The concepts of 'a good job' and 'a job good for health' were also discussed. Interactions with others and the job itself were the most commonly used criteria and were also the most common features of a 'good job'. Pay and security were mentioned frequently but were less important when comparing jobs and when defining a 'good job'. Physical activity was rarely associated by interviewees with a 'good job' but was frequently associated with a 'job good for health'. A comprehensive definition of a 'good job' needs to take all these factors into account.
