Areas of Privacy in Facebook: Expectations and Value

Privacy issues surrounding the use of social media sites have been apparent over the past ten years. Use of such sites, particularly Facebook, has been increasing and recently business organizations have begun using Facebook as a means of connecting with potential customers or clients. This paper presents an empirical study of perceived privacy violations to examine factors that in!uence the expectations of privacy on Facebook. Results of the study suggest that the more important Facebook is to users, the more likely they are to perceive privacy violations and the more likely those violations are to be considered serious. Furthermore, how information is used is more important than the way this information is accessed

Ethical Decision-making: Special or No Different?

Theories of ethical decision-making assume it is a process that is special, or different in some regard from typical individual decision-making. Empirical results of the most widely known theories in the field of business ethics contain numerous inconsistencies and contradictions. In an attempt to assess why we continue to lack understanding of how individuals make ethical decisions at work, an inductive study of ethical decision-making was conducted. The results of this preliminary study suggest that ethical decision-making might not be meaningfully “special” or different from other decision-making processes. The implications of this research are potentially significant in that they challenge the fundamental assumption of existing ethical decision-making research. This research could serve as an impetus for further examination of whether ethical decision-making is meaningfully different from other decision-making processes. Such studies could create new directions for the field of business ethics

Associations between health-related quality of life, physical function and fear of falling in older fallers receiving home care

Falls and injuries in older adults have significant consequences and costs, both personal and to society. Although having a high incidence of falls, high prevalence of fear of falling and a lower quality of life, older adults receiving home care are underrepresented in research on older fallers. The objective of this study is to determine the associations between health-related quality of life (HRQOL), fear of falling and physical function in older fallers receiving home care

Combined effects of time spent in physical activity, sedentary behaviors and sleep on obesity and cardio-metabolic health markers: a novel compositional data analysis approach

<div><p>The associations between time spent in sleep, sedentary behaviors (SB) and physical activity with health are usually studied without taking into account that time is finite during the day, so time spent in each of these behaviors are codependent. Therefore, little is known about the combined effect of time spent in sleep, SB and physical activity, that together constitute a composite whole, on obesity and cardio-metabolic health markers. Cross-sectional analysis of NHANES 2005–6 cycle on N = 1937 adults, was undertaken using a compositional analysis paradigm, which accounts for this intrinsic codependence. Time spent in SB, light intensity (LIPA) and moderate to vigorous activity (MVPA) was determined from accelerometry and combined with self-reported sleep time to obtain the 24 hour time budget composition. The distribution of time spent in sleep, SB, LIPA and MVPA is significantly associated with BMI, waist circumference, triglycerides, plasma glucose, plasma insulin (all p<0.001), and systolic (p<0.001) and diastolic blood pressure (p<0.003), but not HDL or LDL. Within the composition, the strongest positive effect is found for the proportion of time spent in MVPA. Strikingly, the effects of MVPA replacing another behavior and of MVPA being displaced by another behavior are asymmetric. For example, re-allocating 10 minutes of SB to MVPA was associated with a lower waist circumference by 0.001% but if 10 minutes of MVPA is displaced by SB this was associated with a 0.84% higher waist circumference. The proportion of time spent in LIPA and SB were detrimentally associated with obesity and cardiovascular disease markers, but the association with SB was stronger. For diabetes risk markers, replacing SB with LIPA was associated with more favorable outcomes. Time spent in MVPA is an important target for intervention and preventing transfer of time from LIPA to SB might lessen the negative effects of physical inactivity.</p></div

Representing Wholeness: Learning via Theatrical Productions

To facilitate learning in a complete way means engaging in a holistic experience of learning that includes both artistic and discursive forms of representation. This requires the learner to be wholly present in the moment and capable of understanding and linking both the rational and emotional dimensions of learning and knowing. Consistent with previous work in organizational and reflective learning, the authors suggest that the use of theatre is a powerful tool to create this wholeness, and present reflections on our experience regarding this supposition. The authors then discuss further applications of this experience to enhance learning

Adopting a Patient-Centered Approach to Primary Outcome Analysis of Acute Stroke Trials Using a Utility-Weighted Modified Rankin Scale.

Background and purposeAlthough the modified Rankin Scale (mRS) is the most commonly used primary end point in acute stroke trials, its power is limited when analyzed in dichotomized fashion and its indication of effect size challenging to interpret when analyzed ordinally. Weighting the 7 Rankin levels by utilities may improve scale interpretability while preserving statistical power.MethodsA utility-weighted mRS (UW-mRS) was derived by averaging values from time-tradeoff (patient centered) and person-tradeoff (clinician centered) studies. The UW-mRS, standard ordinal mRS, and dichotomized mRS were applied to 11 trials or meta-analyses of acute stroke treatments, including lytic, endovascular reperfusion, blood pressure moderation, and hemicraniectomy interventions.ResultsUtility values were 1.0 for mRS level 0; 0.91 for mRS level 1; 0.76 for mRS level 2; 0.65 for mRS level 3; 0.33 for mRS level 4; 0 for mRS level 5; and 0 for mRS level 6. For trials with unidirectional treatment effects, the UW-mRS paralleled the ordinal mRS and outperformed dichotomous mRS analyses. Both the UW-mRS and the ordinal mRS were statistically significant in 6 of 8 unidirectional effect trials, whereas dichotomous analyses were statistically significant in 2 to 4 of 8. In bidirectional effect trials, both the UW-mRS and ordinal tests captured the divergent treatment effects by showing neutral results, whereas some dichotomized analyses showed positive results. Mean utility differences in trials with statistically significant positive results ranged from 0.026 to 0.249.ConclusionsA UW-mRS performs similar to the standard ordinal mRS in detecting treatment effects in actual stroke trials and ensures the quantitative outcome is a valid reflection of patient-centered benefits
