the purpose of this research is to contribute to the theorizing of ITIL. The paper provides a model that conceptualizes the scope and content of an ITIL implementation project, and it tests and validates measurements based on a literature study and data from a survey of 446 Nordic ITIL experts. © 2011 IEEE.

To curb the trend towards obesity and unhealthy living, people may need to change their entire lifestyle to a healthier alternative, something that is frequently perceived to be problematic. The present research, using a large, representative community sample, hypothesized and found that a key factor responsible for why people do not intend to change lifestyles is a sense of commitment to past behavior. However we also found that the contribution of commitment was attenuated for individuals with a stronger tendency for behavioral disinhibition thus underscoring the "bright side" of this individual difference characteristic that traditionally has been mainly associated with impulsive and indulging behavior. Overall, the present findings add to our understanding of factors inhibiting and promoting healthy behavior change. © 2015 Fennis et al.This is an open access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited.

Background: A study was conducted in VIMS hospital at Bellary during the epidemic of August 2004 to July 2005. Objectives: To know the hospital based incidence of J.E and to study the age and sex pattern of the infection in the paediatric age group. Materials and Methods: 82 children admitted to the Paediatric ward, VIMS, Bellary with clinical diagnosis of acute viral encephalitis, during the epidemic of August 2004 to July 2005 were studied. After pooling the samples, they were subjected to J.E. MAC ELISA. Results: Out of 82 patients tested by J.E. MAC ELISA, 19 (24%) were positive for J.E. and 12 (14.63%) were positive for flaviviral infection. CSF was positive in all 19 cases with 100% positivity. Serum was positive in 10 cases with 15.87% positivity. This indicates that there are significant number of J.E. cases in Bellary emphasising the rampant nature and stressing the measures to be taken to overwhelm this devastating disease. Conclusion: The hospital based incidence of J.E. was found to be significant in the area of the study. The paediatric age group, between 4to 6 years was found to be most predisposed to J.E., probably because of low immunity in the age group. Male predominance was seen with male to female ratio of 1.42:1. Illiteracy, low socio economic status and living in unhygienic conditions near rice fields contributed to the high incidence of J.E. in and around Bellary. The serological results clearly establish the etiology. Isolation of JEV from specimens would have strengthened the diagnosis. Source

A warmer climate may result in lower thermal efficiency and reduced load-including shutdowns-in thermal power plants. Focusing on nuclear power plants, we use different European datasets and econometric strategies to identify these two supply-side effects. We find that a rise in temperature of 1°C reduces the supply of nuclear power by about 0.5% through its effect on thermal efficiency; during droughts and heat waves, the production loss may exceed 2.0% per degree Celsius because power plant cooling systems are constrained by physical laws, regulations and access to cooling water. As climate changes, one must consider measures to protect against and/or to adapt to these impacts. Copyright © 2011 by the IAEE. Source

We present a multispecies stochastic model that suggests optimal fishing policy for two species in a three-species predator-prey ecosystem in the Barents Sea. We employ stochastic dynamic programming to solve a three-dimensional model, in which the catch is optimized by using a multispecies feedback strategy. Applying the model to the cod, capelin, and herring ecosystem in the Barents Sea shows that the optimal catch for the stochastic interaction model is more conservative than that implied by the deterministic model. We also find that stochasticity has a stronger effect on the optimal exploitation policy for prey (capelin) than for predator (cod). © 2015 Wiley Periodicals, Inc. Source
