Practice parameters for the surgical modifications of the upper airway for obstructive sleep apnea in adults.

Abstract: Background: Practice parameters for the treatment of obstructive sleep apnea syndrome (OSAS) in adults by surgical modification of the upper airway were first published in 1996 by the American Academy of Sleep Medicine (formerly ASDA). The following practice parameters update the previous practice parameters. These recommendations were reviewed and approved by the Board of Directors of the American Academy of Sleep Medicine.

Gut microbiota, intestinal permeability, obesity-induced inflammation, and liver injury.

Abstract: Obesity and its metabolic complications are major health problems in the United States and worldwide, and increasing evidence implicates the microbiota in these important health issues. Indeed, it appears that the microbiota function much like a metabolic “organ,” influencing nutrient acquisition, energy homeostasis, and, ultimately, the control of body weight. Moreover, alterations in gut microbiota, increased intestinal permeability, and metabolic endotoxemia likely play a role in the development of a chronic low-grade inflammatory state in the host that contributes to the development of obesity and associated chronic metabolic diseases such as nonalcoholic fatty liver disease. Supporting these concepts are the observations that increased gut permeability, low-grade endotoxemia, and fatty liver are observed in animal models of obesity caused by either high-fat or high-fructose feeding. Consistent with these observations, germ-free mice are protected from obesity and many forms of liver injury. Last, man...

Predicting risks of larceny theft victimization: a routine activity analysis using refined lifestyle measures

Abstract: Routine activity theory has long been plagued by a heavy reliance on proxy measures of lifestyles, which typically include demographic variables that are regularly used as measures of lifestyle and behavior. This reliance on indirect measures forces researchers to suppose how and why these indicators are related to victimization risks. Using detailed measurements of activities and specific structural aspects of communities is clearly more desirable and beneficial when seeking to explain variances in victimization risks. This research advances theoretical understandings of victimization risks through an analysis of specific social activities, aspects of neighborhoods, and contribution of each to the risks of larceny victimization for college students. We find that greater specificity in measuring lifestyles is warranted, for it is not just leaving one's home and going out in public that increases one's risk for victimization (a typical finding of routine activity theory scholars), but where one goes and what one does that are the important larceny victimization predictors.

The Role of Communication and Trust in Global Virtual Teams: A Social Network Perspective

Abstract: The importance of communication and trust in the context of global virtual teams has been noted and reiterated in the information systems (IS) literature. Yet precisely how communication and trust influence certain outcomes within virtual teams remains unresolved. In this study, we seek to contribute some clarity to the understanding of the theoretical linkages among trust, communication, and member performance in virtual teams. To this end, we identify and test three proposed models (additive, interaction, and mediation) describing the role of trust in its relationship with communication to explain performance. In testing the relationships, we note that the concepts of communication and trust are inherently relational and not properties of individuals. Thus, we argue that a social network approach is potentially more appropriate than attribute-based approaches that have been utilized in prior research. Our results indicate that the "mediating" model best explains how communication and trust work together to influence performance. Overall, the study contributes to the existing body of knowledge on virtual teams by empirically reconciling conflicting views regarding the interrelationships between key constructs in the literature. Further, the study, through its adoption of the social network analysis approach, provides awareness within the IS research community of the strengths of applying network approaches in examining new organizational forms.
