The impact of electronic commerce on business-level strategies

Abstract: This paper examines the impact of electronic commerce on business-level strategies. The paper examines electronic commerce (E.C) from the perspective of intra-business E.C., business-to-business E.C., business-toconsumer E.C., and value/supply chain management. Business-level strategies are considered to include: addedvalue, differentiation, cost leadership, focus, and growth source. The paper concludes that E-commerce will have significant impacts on each of the business-level strategic areas.

The role of cultural factors on clients' attitudes toward caregiving, perceptions of service delivery, and service utilization.

Abstract: SUMMARY The purpose of the present study was to gain a better understanding of the role of culture in the use of respite services. Culture was defined in three different ways: (1) ethnicity (African-American, Hispanic/Latino, or White); (2) relationship of the caregiver to the care receiver (spouse, adult-child, or other); and (3) geographic location (urban or rural). All three of these classifications were significantly related to the use of respite services, even after controlling for elders' income. Two sets of potential intervening variables that might explain the effects of culture on respite use were investigated: caregivers' attitudes and beliefs, and clients' evaluation of aspects of service delivery. When these variables were controlled, the main effects for relationship of the care-giver to the care receiver and geographic location on respite use were no longer significant. The effect of ethnicity on respite use persisted in the presence of these controls, but was greatly diminished. The results...

Self-Awareness and the Evolution of Leaders: The Need for a Better Measure of Self-Awareness

Abstract: A growing body of empirical research suggests that self-awareness is associated with successful leadership. Although self-awareness research has generated a number of scales to measure self-awareness, none have done so with the explicit focus of leadership. The present research is a summary of three studies designed to develop and begin validation for a scale to measure self-awareness in the context of leadership and leader development. The result of Study 1 and 2 was a 54-item self-awareness scale. A confirmatory factor analysis provided evidence for a marginal fit. Predictive validity was assessed in Study 3 by looking for associations between self-awareness and outcomes from an MBA capstone course designed in part to improve communication, foster teamwork, and increase self-awareness. Self-awareness was the independent variable. The dependent variables were the graded, videotaped outcomes of two types of structured role-playing exercises designed to meet course objectives and involved students working in dyads or in small groups. Positive associations were found between the new scale and some group context measures of performance, but not for the dyad measures. Implications and suggestions for future research are provided.

Comparison of Wearable Trackers' Ability to Estimate Sleep.

Abstract: Tracking physical activity and sleep patterns using wearable trackers has become a current trend. However, little information exists about the comparability of wearable trackers measuring sleep. This study examined the comparability of wearable trackers for estimating sleep measurement with a sleep diary (SD) for three full nights. A convenience sample of 78 adults were recruited in this research with a mean age of 27.6 ± 11.0 years. Comparisons between wearable trackers and sleep outcomes were analyzed using the mean absolute percentage errors, Pearson correlations, Bland–Altman Plots, and equivalent testing. Trackers that showed the greatest equivalence with the SD for total sleep time were the Jawbone UP3 and Fitbit Charge Heart Rate (effect size = 0.09 and 0.23, respectively). The greatest equivalence with the SD for time in bed was seen with the SenseWear Armband, Garmin Vivosmart, and Jawbone UP3 (effect size = 0.09, 0.16, and 0.07, respectively). Some of the wearable trackers resulted in closer approximations to self-reported sleep outcomes than a previously sleep research-grade device, these trackers offer a lower-cost alternative to tracking sleep in healthy populations.
