Preliminary Evidence for the Neurophysiologic Effects of Online Coupons: Changes in Oxytocin,Stress, and Mood 下载免费PDF全文
Coupon use saved consumers $2.9 billion on packaged goods in 2012 with over 90 million Americans using online coupons. Besides saving money, why is coupon use so widespread? An experiment was run where participants (N = 90) shopped online and one‐half received a coupon worth $10. It was found that those who received a coupon had a 14% increase in oxytocin (OT), an 8% decrease in the stress hormone adrenocorticotropin, a 4% decrease in heart rate (HR), a 27% decrease in respiration, a 4% decrease in skin conductance levels, and a 90% increase in high‐frequency HR variability. These factors showed almost no change for those who did not receive a coupon. The findings indicate that coupons elicit physiological reactions similar to having a positive social interaction. In addition, self‐reported happiness correlated with the change in OT (r = 0.43). These findings provide new insights into why online coupon use is so pervasive. 相似文献

When Stress Frustrates and When It Does Not: Configural Models of Frustrated versus Mellow Salespeople 下载免费PDF全文
The purpose of this study is to elucidate the stress–strain relationship by examining compound causes of frustration in the workplace. Drawing on configuration theory, this article describes stress patterns, that is, configurations of role stressors and social stressors, and underlying frustration and its negation, that is, mellowness. In addition, this article describes potential sources of such frustration‐stimulating stress patterns by examining constellations of employee and task characteristics. Based on a sample of 118 salespeople, the authors analyze the data using fuzzy‐set Qualitative Comparative Analysis—an analytic method pertinent to describing configurational patterns of causal factors. The findings from this study indicate the coexistence of alternative patterns of stressors for frustration. In addition, the findings show that configurational patterns for frustrated salespeople are quite different from those characterizing mellow salespeople. In summary, knowledge of these constellations of stressors helps sales managers detect conditions that frustrate, and develop strategies to diminish these conditions in order to improve sales force performance. 相似文献

This paper uses a composite measure to examine why some countries attract more foreign direct investment (FDI) than others. The measure considers all identified, measurable, and comparable socioeconomic aspects that affect FDI decisions on an aggregated country level. As a result, we can rank 127 countries with respect to their FDI attraction. The measure allows detailed strength and weakness analyses and enhances the discussion of why FDI flows are concentrated in advanced economies. Additionally, the findings reveal the areas in which emerging countries should improve in order to narrow existing gaps. Our robustness checks indicate that the composite measure accurately tracks real FDI activity. 相似文献

We introduce several regime‐dependent smile‐adjusted deltas and compare their efficiency with the smile‐adjusted deltas that are popular with option traders. Using years of daily option prices, out‐of‐sample hedging performance tests for options of all moneyness and maturities and daily, weekly, or fortnightly rebalancing show that even the simplest regime‐dependent smile‐adjustment consistently outperforms implied BSM delta hedging and local volatility and minimum variance smile‐adjustments. Markov‐switching deltas offer the best performance, with delta‐hedging errors often half the size of implied BSM hedging errors. During volatile markets risk reduction from regime‐dependent delta hedging is much greater than during tranquil periods. 相似文献

AV Kudryavtsev O Nilssen Y Sumarokov B Ytterstad 《International journal of injury control and safety promotion》2012,19(3):290-296
The Global Burden of Disease Studies describe and emphasise injury as a major and increasing component in the panorama of global ill health. Russia has the one of the highest injury rates in Europe. When a Master in Public Health programme was planned and started in 2007 in Arkhangelsk, Russia, under the auspices of University of Troms?, Norway, a course on Injury Prevention and Safety Promotion was included. A take-over programme (training-the-trainers) was implemented within the course. The present paper describes the course content, the students and their background, the training-the-trainers programme, the evaluation procedure and its results. So far, 53 students have passed the course, 77% being female. The majority of students were medical doctors (51%), psychologists (11%), pedagogues (9%), dentists (6%) and nurses (6%). The take-over programme has functioned well by gradually using students of excellence as teachers. In 2012, the take-over programme is completed and only Russians teach. Evaluation by students of the course content, organisation and pedagogic approach was useful for improvements. 相似文献
