Health authorities in several countries have decided that the health care services should be evidence-based. Recent research indicates that evidence-based practice may be more successfully implemented if the interventions overcome identified barriers. The present study aimed to examine factors influencing the implementation of evidence-based practice among nurses in a large Norwegian university hospital. Cross-sectional data was collected from 407 nurses during the period November 8 to December 3, 2010, using the Norwegian version of Developing Evidence-based Practice questionnaire (DEBP). The DEBP included data on various sources of information used for support in practice, on potential barriers for evidence-based practice, and on self-reported skills on managing research-based evidence. The DEBP was translated into Norwegian in accordance with standardized guidelines for translation and cultural adaptation. Nurses largely used experienced-based knowledge collected from their own observations, colleagues and other collaborators for support in practice. Evidence from research was seldom used. The greatest barriers were lack of time and lack of skills to find and manage research evidence. The nurse's age, the number of years of nursing practice, and the number of years since obtaining the last health professional degree influenced the use of sources of knowledge and self-reported barriers. Self-reported skills in finding, reviewing and using different sources of evidence were positively associated with the use of research evidence and inversely related to barriers in use of research evidence. Skills in evidence-based practice seem to reduce barriers to using research evidence and to increase use of research evidence in clinical practice.

Background Depression and anxiety are particularly common among individuals living in long-term care facilities. Therefore, access to a valid and reliable measure of anxiety and depression among nursing home patients is highly warranted. Aim To investigate the dimensionality, reliability and construct validity of the Hospital Anxiety and Depression scale (HADS) in a cognitively intact nursing home population. Methods Cross-sectional data were collected from two samples; 429 cognitively intact nursing home patients participated, representing 74 different Norwegian nursing homes. Confirmative factor analyses and correlations with selected constructs were used. Results The two-factor model provided a good fit in Sample1, revealing a poorer fit in Sample2. Good-acceptable measurement reliability was demonstrated, and construct validity was supported. Limitations Using listwise deletion the sample sizes were 227 and 187, for Sample1 and Sample2, respectively. Greater sample sizes would have strengthen the statistical power in the tests. The researchers visited the participants to help fill in the questionnaires; this might have introduced some bias into the respondents reporting. The 14 HADS items were part of greater questionnaires. Thus, frail, older NH patients might have tired during the interview causing a possible bias. Conclusion Low reliability for depression was disclosed, mainly resulting from three items appearing to be inappropriate indicators for depression in this population. Further research is needed exploring which items might perform as more reliably indicators for depression among nursing home patients. © 2014 Elsevier B.V.

The present paper deals with the parents' narratives of sickness and misfortune of their children among the Beja people in the Red Sea Hills, Northeastern Sudan. Drawing on fieldwork focusing parents' health-seeking behavior related to child sicknesses through 1993-95, and combining participant observation and interviews, the aim is firstly to elucidate how markers of uncertainty is a pronounced trait of Beja sickness narratives, inviting listeners to actively engage in the stories, adding to a still scarce but growing literature on narration and uncertainty. Secondly, it aims at relating this narrative style to wider contexts of Beja culture and society, a type of analysis seldom undertaken within the field of medical anthropology. It is argued that although some facets of the lives of Beja people have changed since the time of the fieldwork, the changes are not pronounced and have not changed the cultural environment so as to make the analysis and conclusions of this paper less valid.

Wireless Sensor Networks (WSNs) are applicable in numerous domains, including industrial automation where WSNs may be used for monitoring and control of industrial plants and equipment. However, the requirements in the industrial systems differ from the general WSN requirements. In recent years, standards have been defined by several industrial alliances. These standards are specified as frameworks with modifiable parts that can be defined based on the particular application of WSN. However, limited work has been done on defining industry-specific protocols that could be used as a part of these standards. In this survey, we discuss representative protocols that meet some of the requirements of the industrial applications. Since the industrial applications domain in itself is a vast area, we divide them into classes with similar requirements. We discuss these industrial classes, set of common requirements and various state-of-the-art WSN standards proposed to satisfy these requirements. We then present a broader view towards the WSN solution by discussing important functions like medium access control, routing, and transport in detail to give some insight into specific requirements and the classification of protocols based on certain factors. We list and discuss representative protocols for each of these functions that address requirements defined in the industrial classes. Security function is discussed in brief, mainly in relation to industrial standards. Finally, we identify unsolved challenges that are encountered during design of protocols and standards. In addition some new challenges are introduced and discussed. © 2014 IEEE.

In 1942, Katherine Frost Bruner published an article titled "Of psychological writing: Being some valedictory remarks on style." It was published in Journal of Abnormal and Social Psychology, the journal for which she served as editorial assistant between 1937 and 1941. Her collection of advice to writing scholars has been widely quoted, including by several editions of The Publication Manual of the American Psychological Association. The most frequently quoted message in Bruner's article deals with the importance of making sure that references in academic texts are complete and accurate. Exploring the citation history of this particular message reveals an ironic point: the great majority of those who have quoted Bruner's words on reference accuracy have not done so accurately. The case may serve as a reminder of the importance of the basic academic principle of striving to use primary sources. The most startling finding in this study is how frequently this principle is violated, even by authors who advise and educate academic writers. © The Author(s) 2014.

Most vaginal births are associated with some form of trauma to the genital tract. The morbidity associated with perineal trauma is significant, especially when it comes to third- and fourth-degree tears. Different perineal techniques and interventions are being used to prevent perineal trauma. These interventions include perineal massage, warm compresses and perineal management techniques. The objective of this review was to assess the effect of perineal techniques during the second stage of labour on the incidence of perineal trauma. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (20 May 2011), the Cochrane Central Register of ControlledTrials (The Cochrane Library 2011, Issue 2 of 4), MEDLINE (January 1966 to 20 May 2011) and CINAHL (January 1983 to 20 May 2011). Published and unpublished randomised and quasi-randomised controlled trials evaluating any described perineal techniques during the second stage. Three review authors independently assessed trails for inclusion, extracted data and evaluated methodological quality. Data were checked for accuracy. We included eight trials involving 11,651 randomised women. There was a significant effect of warm compresses on reduction of third- and fourth-degree tears (risk ratio (RR) 0.48, 95% confidence interval (CI) 0.28 to 0.84 (two studies, 1525 women)). There was also a significant effect towards favouring massage versus hands off to reduce third- and fourth-degree tears (RR 0.52, 95% CI 0.29 to 0.94 (two studies, 2147 women)). Hands off (or poised) versus hand on showed no effect on third- and fourth-degree tears, but we observed a significant effect of hands off on reduced rate of episiotomy (RR 0.69, 95% CI 0.50 to 0.96 (two studies, 6547 women)). The use of warm compresses on the perineum is associated with a decreased occurrence of perineal trauma. The procedure has shown to be acceptable to women and midwives. This procedure may therefore be offered to women.

Communication protocols constitute central building blocks in most modern IT systems as they define components, rules, and languages that make data communication possible. The development of correct protocols is a challenging engineering discipline, making modelling and validation of protocol design an important application domain for Coloured Petri Nets (CPNs). We illustrate the practical application of CPNs for protocol validation by focusing on selected aspects of four recent projects involving industrial-sized protocols. These projects demonstrate how CPNs can be used to model protocol elements and improve protocol specifications, how state space exploration can be used to verify protocol properties, and how behavioural visualisation in combination with a CPN model provides an effective way of rapidly constructing an executable prototype of a protocol design. © Springer-Verlag 2013.

Oxygen is generally the first limiting factor for the water flow requirement in a land based aquaculture system, while carbon dioxide and pH are secondary limiting factors. This means that if oxygen is added to the inlet water or directly to the water in a fish tank carbon dioxide becomes the limiting factor. pH is easy to regulate by addition of bicarbonate, while carbon dioxide always will be elevated in both single pass oxygenated systems and in recirculation systems. Carbon dioxide has both direct physiological effects on the fish, as well as indirect effects by changing the pH and thereby the chemistry of metals in the water.During the last 20 years several long-term carbon dioxide experiments have been performed at Bergen University College. In the present paper general methods and findings from the research at Bergen University College are described. These findings are compared with studies performed elsewhere. Increased plasma PCO2 increases the plasma bicarbonate concentration and reduces the plasma chloride concentration. In a long-term carbon dioxide experiment on Atlantic salmon postsmolts about 94% of the total variation in plasma carbon dioxide partial pressure was explained by the partial pressure in the water in a simple linear regression model, and 72% of the total variation in plasma chloride was explained by the plasma bicarbonate concentration. There was a reduction in about 1mM Cl- for every 1mM increase in plasma bicarbonate.For carbon dioxide the safe criterion used for the Norwegian production of Atlantic salmon smolts is 15mgL-1. In low alkalinity fresh water carbon dioxide has adverse effects on fish in combination with labile Al/pH at concentrations around 8-10mgL-1 CO2, and the smolts are not acclimated to such conditions. When toxic Al is not present in the water 8-10mgL-1 carbon dioxide may have slight but significant effects on condition factor during the first month, but the smolts seem to be acclimated to these conditions after 2 months. However, when the concentration of carbon dioxide is 17-19mgL-1 (5-6mmHg) in low alkalinity water, condition factor or specific growth rate is reduced after 2 months exposure.In high alkalinity fresh water, carbon dioxide had only minor effects on growth up to 24mgL-1, however, further research may be needed to validate this and to study how the safe threshold level for carbon dioxide is influenced by temperature and salinity. © 2012 Elsevier B.V..

The ability to observe the internals of an execution of a computer-based system is a fundamental requirement for ultimately ensuring correctness and safe behaviour. Within COEMS (Continuous Observation of Embedded Multicore Systems) a novel observer platform with supporting verification methods for software systems is created. COEMS tackles the issues of detection and identification of non-deterministic software failures caused by race conditions and access to inconsistent data. It gives insight to the systems actual behaviour without affecting it allowing new verification methods. An efficient real-time access and analysis as a critical element for operating safe systems will be developed and validated by COEMS. Moreover, a cross-layer programming approach supporting failure detection will be proposed. COEMS aims at shortening the development cycle by considerably increased test efficiency and effectivity, by increased debug efficiency (especially for non-deterministically occurring failures) and by supporting performance optimization. COEMS improves the reliability of delivered systems, enabling software developers to identify, understand, and remove software defects before release, as well as improving efficiency of software for multi/many-core computing systems in terms of performance, real-time behaviour, and energy consumption. The two Global Players Thales Group and Airbus Group, both active in safety-critical domains, will validate the COEMS approach by suitable demonstrators, i.e. testing and debugging of real-world multicore applications. In addition to these two domains, we will address the domains of safety-critical medical applications, automation and automotive industry, as well as the Internet of Things. Technologically, COEMS will provide the world-wide first comprehensive online observation approach that is non-intrusive allowing improved testing and debugging. Altogether, COEMS will define a new state-of-the-art for software systems development.
