CONTEXT Although meta-analyses of randomized trials have shown that selective digestive decontamination (SDD) prevents nosocomial pneumonia in critically ill patients, the influence of trial quality on the effectiveness of SDD has not been rigorously evaluated. OBJECTIVE To assess the methodological quality of individual studies of SDD and its relation to the reported effects on pneumonia and...

The widespread availability of the Internet offers opportunities for improving access to therapy for people with mental health problems. There is a seemingly infinite supply of Internet-based interventions available on the World Wide Web. The aim of the present study is to systematically assess the methodological quality of randomized controlled trials (RCTs) concerning e-therapy for mental hea...

BACKGROUND Health care systems that succeed in preventing long term care and hospital admissions of frail older people may substantially save on their public spending. The key might be found in high-quality care in the community. Quality Indicators (QIs) of a sufficient methodological level are a prerequisite to monitor, compare, and improve care quality. This systematic review identified exist...

We develop a dynamic model of sustainable competitive advantage in hypercompetitive environments. We argue that competitive advantages of firms can be sustainable even if resource-based advantages of firms can be quickly replicated by rivals or when the barriers to entry are almost non-existent. This is accomplished through intensive entrepreneurial activity of firms during the equilibrating te...

1. When customers call in, their orders and credit card information are received by the customer service department. 2. Once the order is received, the order details and credit card information is sent to the Finance department for processing. 3. If the credit card authorization is unsuccessful, then the Finance department sends a “rejection” notification to the Customer Service department. 4. ...

In ecommerce, many market followers would like to have personalization systems in place to more effectively compete with market leaders. However, retailers face a significant challenge in forming initial trust with new customers, especially when the new customers are culturally diverse. Acknowledging this dilemma, this study examines the moderating cultural effects of espoused individualism/col...

UNLABELLED A new form of literature review has emerged, Mixed Studies Review (MSR). These reviews include qualitative, quantitative and mixed methods studies. In the present paper, we examine MSRs in health sciences, and provide guidance on processes that should be included and reported. However, there are no valid and usable criteria for concomitantly appraising the methodological quality of t...

Current work suggests that individualistic values are more likely to be invoked in judgments about welfare recipients when the latter are black. Nevertheless, this “racialization” hypothesis has yet to be directly tested by looking at whether generalized individualism is more strongly related to hostility toward welfare recipients among whites when the recipients are black. In this paper, I con...

The thesis of methodological individualism in social science is commonly divided into two different claims – explanatory individualism and ontological individualism. Ontological individualism is the thesis that facts about individuals exhaustively determine social facts. Initially taken to be a claim about the identity of groups with sets of individuals or their properties, ontological individu...
