The Effects of Relational Coordination and Supervisor Support on Thriving and Job Satisfaction: Evidence from Sales Professional in U.S. Small Businesses

Job satisfaction is often fostered through costly strategic human resource management practices, yet small businesses typically lack the required resources to employ such practices. The current study explores other avenues for promoting job satisfaction, namely thriving, which is a psychological state in which individuals experience both a sense of learning and a sense of vitality. By leveraging positive organizational psychology, and examining data collected from B2B salespeople, this study demonstrates the value of relational coordination and supervisor support for enhancing the thriving, and, in turn, job satisfaction of sales professionals among small businesses

Reflecting on Performance Feedback: The Effect of Counterfactual Thinking on Subsequent Leader Performance

Performance feedback is an integral aspect of facilitating employee learning. Despite its importance, research suggests that when that feedback conveys a performance discrepancy, subsequent performance does not improve. Researchers have advanced reflection as a strategy for increasing feedback effectiveness and have established its value for learning and performance improvement. However, these studies have not accounted for the effects of specific types of reflection on performance. To this point, the current research examines the role of one form of reflection, counterfactual thinking, for learning after performance discrepancies. I explored boundary conditions that might influence self-focused upward counterfactual thinking—a form of reflection particularly important for learning and performance improvement—and examined whether and when such thinking influences the relationship between a baseline performance discrepancy and subsequent performance. To investigate these issues, I designed, developed, and validated a computer simulated leadership skills task and administered it to graduate and undergraduate students (N= 169) in a web-based research setting. I tested the proposed relationships using conditional process analysis. The results of this study demonstrated that when individuals encounter performance discrepancies they might attempt to reconcile such through self-focused upward counterfactual thinking. This research represents a step toward an improved understanding of reflection, performance discrepancy feedback processing, and subsequent performance effects

Decision Support Variables for Reverse Logistics

The purpose of this study is to discover variables that should be considered in the creation of a strategic knowledge and decision support system for reverse logistics. This paper addresses a gap in the Lambert model of supply chain management through refining the link between the returns management process and the overall strategy of a supply chain firm by addressing the decision as to which reverse logistics activity to pursue. Current literature is sparse in this area and existing DSS do not specifically address this problem. In order to determine what variables should be considered in such a system, recent reverse logistics frameworks which address returned-products disposition were reviewed. Using an inductive literature review process and subsequent content analysis, the authors found seven factors that are relevant to reverse logistics disposition. Propositions are offered for further research in this area.

Seasonal Snow Extent and Snow Mass in South America using SMMR and SSM/I Passive Microwave Data (1979-2006)

Seasonal snow cover in South America was examined in this study using passive microwave satellite data from the Scanning Multichannel Microwave Radiometer (SMMR) on board the Nimbus-7 satellite and the Special Sensor Microwave Imagers (SSM/I) onboard Defense Meteorological Satellite Program (DMSP) satellites. For the period from 1979-2006, both snow cover extent and snow water equivalent (snow mass) were investigated during the coldest months (May-September), primarily in the Patagonia area of Argentina and in the Andes of Chile, Argentina and Bolivia, where most of the seasonal snow is found. Since winter temperatures in this region are often above freezing, the coldest winter month was found to be the month having the most extensive snow cover and usually the month having the deepest snow cover as well. Sharp year-to-year differences were recorded using the passive microwave observations. The average snow cover extent for July, the month with the greatest average extent during the 28-year period of record, is 321,674 km(exp 2). In July of 1984, the average monthly snow cover extent was 701,250 km(exp 2) the most extensive coverage observed between 1979 and 2006. However, in July of 1989, snow cover extent was only 120,000 km(exp 2). The 28-year period of record shows a sinusoidal like pattern for both snow cover and snow mass, though neither trend is significant at the 95% level

All-optical binary counter

We experimentally demonstrate an all-optical binary counter composed of four semiconductor optical amplifier based all-optical switching gates. The time-of-flight optical circuit operates with bit-differential delays between the exclusive-OR gate used for modulo-2 binary addition and the AND gate used for binary carry detection. A movie of the counter operating in real time is presented

Seasonal Snow Extent and Snow Mass in South America Using SMMR and SSM/I Passive Microwave Data (1979-2003)

Seasonal snow cover in South America was examined in this study using passive microwave satellite data from the Scanning Multichannel Microwave Radiometer (SMMR) on board the Nimbus-satellite and the Special Sensor Microwave Imagers (SSM/I) on board Defense Meteorological Satellite Program (DMSP) satellites. For the period from 1979-2003, both snow cover extent and snow depth (snow mass) were investigated during coldest months (May-September), primarily in the Patagonia area of Argentina and in Chile. Most of the seasonal snow in South America is in the Patagonia region of Argentina. Since winter temperatures in this region are often above freezing, the coldest winter month was found to be the month having the most extensive snow cover and also usually the month having the deepest snow cover as well. Sharp year-to-year differences were recorded using the passive microwave observations. The average snow cover extent for July, the month with the greatest average snow extent during the 25-year period of record, is 320,700 km(exp 2). In July of 1984, the average monthly snow cover was 701,250 km(exp 2) - the most extensive coverage observed between 1979 and 2003. However, in July of 1989, snow cover extent was only 120 km(exp 2). The 25-year period of record shows a sinusoidal like pattern, though there appears to be no obvious trend in either increasing or decreasing snow extent or snow mass between 1979 and 2003

Risk factors for transmission of Ebola or Marburg virus disease: a systematic review and meta-analysis

Background The Ebola virus disease outbreak that started in Western Africa in 2013 was unprecedented because it spread within densely populated urban environments and affected many thousands of people. As a result, previous advice and guidelines need to be critically reviewed, especially with regard to transmission risks in different contexts. Methods Scientific and grey literature were searched for articles about any African filovirus. Articles were screened for information about transmission (prevalence or odds ratios especially). Data were extracted from eligible articles and summarised narratively with partial meta-analysis. Study quality was also evaluated. Results 31 reports were selected from 6552 found in the initial search. Eight papers gave numerical odds for contracting filovirus illness, 23 further articles provided supporting anecdotal observations about how transmission probably occurred for individuals. Many forms of contact (conversation, sharing a meal, sharing a bed, direct or indirect touching) were unlikely to result in disease transmission during incubation or early illness. Amongst household contacts who reported directly touching a case, the attack rate was 32% (95% CI 26-38%). Risk of disease transmission between household members without direct contact was low (1%; 95% CI 0-5%). Caring for a case in the community, especially until death, and participation in traditional funeral rites were strongly associated with acquiring disease, probably due to a high degree of direct physical contact with case or cadaver. Conclusions Transmission of filovirus is unlikely except through close contact, especially during the most severe stages of acute illness. More data are needed about the context, intimacy and timing of contact required to raise the odds of disease transmission. Risk factors specific to urban settings may need to be determined

Effects of supersymmetric grand unification scale physics on Γ(b→sγ)\Gamma \left( b\to s\gamma\right)

Although calculations of the $b\rightarrow s\gamma$ rate in supersymmetric grand unified models have always either ignored the gluino mediated contribution or found it to be negligible, we show that taking universal supersymmetry breaking masses at the Planck scale, rather than at the gauge unification scale as is customary, leads to the gluino contribution being more significant and in fact sometimes even larger than the chargino mediated contributions when $\mu >0$ and $\tan{\beta}$ is of order 1. The impact is greatest felt when the gluinos are relatively light. Taking the universal boundary condition at the Planck scale also has an effect on the chargino contribution by increasing the effect of the wino and higgsino-wino mediated decays. The neutralino mediated contribution is found to be enhanced, but nevertheless it remains relatively insignificant.Comment: Title changed, final version as accepted for PRD, 12 pages, 6 Figures (Figs.2-6 included, uuencoded, epsf.tex
