payoffs from information technology (it) continue to generate interest and debate both among academicians and practitioners. these have led the decision makers to confusion about it effect on firms` financial performance; they don’t know either high or low effect is because of internal or external factors of organizational environment. the mechanism for decreasing the risks is to identify the c...

RFID is very promising for the healthcare industry. However, RFID solutions and contexts of use vary a lot from one place to another and as a consequence its impact on performance can vary as well. Moreover, it can be complex to assess its potential benefits relatively to other solutions before its implementation. We analyze a real project which gathers 18 partners working together to implement...

BACKGROUND Prevalence rates of smoking in people with mental illness are high, and premature mortality attributed to tobacco related physical comorbidity is a major concern. We conducted a meta-analysis comparing rates of receipt of smoking cessation advice among people with and without mental illness. METHOD Major electronic databases were searched from inception till August 2014 for studies...

CONTEXT Many studies report volume abnormalities in diverse brain structures in patients with various mental health conditions. OBJECTIVE To evaluate whether there is evidence for an excess number of statistically significant results in studies of brain volume abnormalities that suggest the presence of bias in the literature. DATA SOURCES PubMed (articles published from January 2006 to Dece...

The standard approach to rank the performance of several classifiers for a given classification problem is via an independent labeled validation dataset. However, in various applications only unlabeled data and several pre-constructed classifiers are provided, without access to labeled training or validation data. This begs the following questions: given only the predictions of several classifi...

Shared understanding is commonly seen as essential to the success of coalition operations, and current research efforts are attempting to develop techniques and technologies to improve shared understanding in military coalition contexts. In spite of this, our understanding of what the term ‘shared understanding’ actually means is surprisingly poor. In part, this problem is attributable to the d...

The current meta-analysis aimed to review the relationship between trait resilience and mental health, and examine some moderating variables such as participant age, gender, and adversity. A total of 60 studies and 111 effect sizes were analyzed. We found that: (1) Trait resilience was negatively correlated to negative indicators of mental health and positively correlated to positive indicators...

The problems with high complexity had been the challenge in combinatorial problems. Due to the none-determined and polynomial characteristics, these problems usually face to unreasonable searching budget. Hence combinatorial optimizations attracted numerous researchers to develop better algorithms. In recent academic researches, most focus on developing to enhance the conventional evolutional a...
