The relation between coronary heart disease (CHD) prevalence and fasting lipid levels was assessed by a case-control study in five populations with a total of 6859 men and women of black, Japanese and white ancestry drawn from subjects aged 40 years and older from populations in Albany, Framingham, Evans County, Honolulu and San Francisco. In each major study group mean levels of high density lipoprotein (HDL) cholesterol were lower in persons with CHD than in those without the disease. The average difference was small -- typically 3-4 mg/dl -- but statistically significant. It was found in most age-race-sex specific groups. The inverse HDL cholesterol-CHD association was not appreciably diminished when adjusted for levels of low density lipoprotein (LDL) cholesterol and triglyceride. LDL, totoal cholesterol and triglycerides were directly related to CHD prevalence; surprisingly, these findings were less uniformly present in the various study groups than the inverse HDL cholesterol-CHD association.

Precursors of sudden death were sought in men--1838 civil servants in Albany, New York, and 2282 residents of Framingham, Massachusetts--under continuous surveillance for 16 years. In men 45-74 years old there were 234 deaths attributed to coronary heart disease (CHD) of which 109 occurred within one hour of onset of symptoms. More than half of all deaths due to CHD occurred outside the hospital and about 80 per cent of these were sudden. Most were unheralded by prior symptoms of CHD. Persons at high risk of death from CHD, including sudden death, can be identified long before the terminal unexpected catastrophe. The same precursive stigmata exist in persons subject ot coronary attacks whether or not immediately fatal. The risk of sudden death in these two populations was positively correlated with high blood pressure, the electrocardiographic pattern of left ventricular enlargement, obesity, and heavy cigarette usage. Sudden death is a common and possibly incidental expression of lethal coronary heart disease. The potential candidate for sudden death cannot be confidently distinguished from the individual who succumbs more slowly of myocardial infarction. The inescapable conclusion is that the prevention of sudden death requires the prevention of coronary attacks.

Adults are living longer, and cardiovascular disease is endemic in the growing population of older adults who are surviving into old age. Functional capacity is a key metric in this population, both for the perspective it provides on aggregate health and as a vital goal of care. Whereas cardiorespiratory function has long been applied by cardiologists as a measure of function that depended primarily on cardiac physiology, multiple other factors also contribute, usually with increasing bearing as age advances. Comorbidity, inflammation, mitochondrial metabolism, cognition, balance, and sleep are among the constellation of factors that bear on cardiorespiratory function and that become intricately entwined with cardiovascular health in old age. This statement reviews the essential physiology underlying functional capacity on systemic, organ, and cellular levels, as well as critical clinical skills to measure multiple realms of function (eg, aerobic, strength, balance, and even cognition) that are particularly relevant for older patients. Clinical therapeutic perspectives and patient perspectives are enumerated to clarify challenges and opportunities across the caregiving spectrum, including patients who are hospitalized, those managed in routine office settings, and those in skilled nursing facilities. Overall, this scientific statement provides practical recommendations and vital conceptual insights.

Baseline 24-hour dietary recalls from 16,349 men ages 45-64 years who had no evidence of coronary heart disease (CHD) were obtained in three prospective studies: the Framingham Study (859 men), the Honolulu Heart Study (7272 men) and the Puerto Rico Heart Health Program (8218 men). These men were followed for up to 6 years for the first appearance of CHD or death. Men who had a greater caloric intake or a greater caloric intake per kilogram of body weight were less likely to develop CHD manifest as myocardial infarction (MI) or CHD death, even though men of greater weight were more likely to develop CHD. This may reflect the benefit of greater physical activity. Men who consumed more alcohol were less likely to develop CHD, but more likely to die of causes other than CHD, particularly in the Honolulu study. In the Honolulu and Puerto Rico studies, but not in the Framingham study, men who consumed more starch were less likely to develop MI or CHD death. There was an inverse relation between starch intake and serum cholesterol, but it was too weak to explain fully the inverse starch-CHD association. There was also no evidence that the inverse relation between starch intake and incidence of CHD in the Honolulu and Puerto Rico studies was an indirect result of differences in fat intake. While the findings suggest additional areas for research, none of them would lead to an alteration of currently recommended preventive diets that emphasize lowering fat intake, because in isocaloric diets the logical way to balance a decreased fat intake is to increase the consumption of foods containing starch.

Child witnesses must endure a delay of around six months between observing or being the victim of an alleged offence and being required to give evidence in a criminal court. While the legal profession seem to believe that young children's memories are particularly sensitive to the passage of time, developmental psychology can offer little relevant data to support or refute this presumption. In the present study, children aged six and nine years and adults witnessed a staged event and were subsequently interviewed in the days following the event and/or five months later. Results indicate that while all witnesses forgot information over this period, the younger children (six years) recalled slightly less information than the older children and the adults. The total amount of incorrect information recalled did not increase over the same period. Two different interviewing techniques were used--cued recall vs. 'enhanced' recall--the latter incorporating some aspects of the cognitive interview procedure. No differences were found relating to the interview techniques employed. The results underline the importance of recording initial interviews with child witnesses wherever possible.

Ranaviruses are globally distributed pathogens in amphibian, fish, and reptile communities that appear to be emerging. Cases of ranavirus infection or disease have been confirmed in at least 105 amphibian species (18 families), 41 fish species (22 families), and 29 reptile species (12 families). Ranaviruses have been documented on all continents except Antarctica, and are frequently associated with mass die-offs. Host susceptibility differs among species, with some species harboring subclinical infections and likely serving as reservoirs for the virus, and other highly susceptible species amplifying the virus. Currently, there are six recognized species of ranavirus, and all are not equally pathogenic among hosts. Frog virus 3 (FV3) is the type species of the genus Ranavirus, and appears to be the most globally distributed species infecting ectothermic taxonomic across three vertebrate classes. International commerce involving subclinically infected ectothermic vertebrates undoubtedly has contributed to the global distribution and emergence of ranaviruses. Herein, we describe the global distributed species infecting ectothermic vertebrates across three taxonomic classes.

OBJECTIVE: Even though the early alliance has been shown to robustly predict posttreatment outcomes, the question whether alliance leads to symptom reduction or symptom reduction leads to a better alliance remains unresolved. To better understand the relation between alliance and symptoms early in therapy, we meta-analyzed the lagged session-by-session within-patient effects of alliance and symptoms from Sessions 1 to 7. METHOD: We applied a 2-stage individual participant data meta-analytic approach. Based on the data sets of 17 primary studies from 9 countries that comprised 5,350 participants, we first calculated standardized session-by-session within-patient coefficients. Second, we meta-analyzed these coefficients by using random-effects models to calculate omnibus effects across the studies. RESULTS: In line with previous meta-analyses, we found that early alliance predicted posttreatment outcome. We identified significant reciprocal within-patient effects between alliance and symptoms within the first 7 sessions. Cross-level interactions indicated that higher alliances and lower symptoms positively impacted the relation between alliance and symptoms in the subsequent session. CONCLUSION: The findings provide empirical evidence that in the early phase of therapy, symptoms and alliance were reciprocally related to one other, often resulting in a positive upward spiral of higher alliance/lower symptoms that predicted higher alliances/lower symptoms in the subsequent sessions. Two-stage individual participant data meta-analyses have the potential to move the field forward by generating and interlinking well-replicable process-based knowledge.

The use of platelet-rich plasma (PRP) to facilitate healing of orthopedic-related injuries has gained popularity; however, the clinical benefits are not consistent. Differences may result from variations in growth factor (GF) levels in normal populations. The purpose of this study was to determine if GF levels present in activated PRP preparations differed by gender and age (≤ 25 versus >25 years) in a healthy population (N = 102). All GFs analyzed (epidermal growth factor [EGF], hepatocyte growth factor [HGF], insulin growth factor-1 [IGF-1], platelet-derived growth factor-AB [PDGF-AB], platelet-derived growth factor-BB [PDGF-BB], transforming growth factor beta-1 [TGFβ-1], and vascular endothelial growth factor) had higher levels for females and for those ≤ 25 years old. Of the GFs tested, four of seven were significantly higher (p < 0.05) for females (EGF, HGF, IGF-1, PDGF-BB), the most significant being IGF-1 (female, 85.0; male, 69.3 ng/mL; p < 0.01). Five of seven GFs achieved significance (p < 0.05) for people ≤ 25 years old (EGF, IGF-1, PDGP-AB, PDGF-BB, and TGFβ-1), with IGF and PDGF-AB achieving p < 0.001 (≤ 25 years, 85.1; >25 years, 56.8, and ≤ 25 years, 7.66; >25 years, 5.77 ng/mL, respectively). Finally, for both genders, most of the GFs were positively correlated with all GFs. This study demonstrated that both age and gender account for variations in specific GFs present in PRP, and this may partially explain some of the inconsistent results of PRP clinical trials.

&lt;strong&gt;Background:&lt;/strong&gt; Entrepreneurship is seen as a driver of sustainable economic growth as entrepreneurs create new businesses and employment. Because entrepreneurship contributes to economic growth, it is important to have the skills needed to be successful in business venturing.&lt;p&gt;&lt;strong&gt;Aim:&lt;/strong&gt; This study’s aim was to determine skills required by South African entrepreneurs to run their businesses.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Setting:&lt;/strong&gt; Entrepreneurs who own and run businesses in South Africa.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Method:&lt;/strong&gt; A sequential exploratory mixed method research design was applied in the study. Phase I, which consisted of qualitative interviews with 15 entrepreneurs and 6 national experts, resulted in skills that were used to develop a survey instrument. A survey was conducted in Phase II on 235 entrepreneurs to confirm the skills to a larger population.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results:&lt;/strong&gt; Confirmatory factor analysis results showed that entrepreneurs require financial management, human resource management, start-up, social and interpersonal, leadership, personality, marketing, technical and business management skills.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion:&lt;/strong&gt; The identified skills through empirical research will be instrumental in the training of entrepreneurs and as a tool to measure skills in future entrepreneurship skills research.&lt;/p&gt;

Labile blood pressure elevation is believed to have less clinical significance than "fixed hypertension." This assertion was examined in the Framingham cohort of 5209 men and women followed for 20 years for the development of cardiovascular events in relation to three routinely measured blood pressures at each of 10 biennial examinations. Variability of pressure judged from the standard deviation about the mean of three pressures was not a consistent characteristic of subjects from one examination to the next (r = 0.07). Higher pressures were more labile than low ones, so that "fixed hypertensives" actually had more labile pressures than did so-called labile hypertensives. Lability, also increased with age. Labile hypertension, determined during a 1-hour period of observation, adds nothing to the ability of the mean blood pressure to predict cardiovascular disease. The mean, minimum and maximum of three pressures measured during an examination were equally efficient predictors of cardiovascular disease. In multivariate analysis, for any given average pressure, risk of cardiovascular events was unaffected by the degree of variability of the pressure. It is recommended that the average of a series of pressures be used to determine risk, preferably over more than one examination.

As a means of promoting critical thinking and connections between theoretical and applied knowledge, case-based instruction (CBI) has been shown to be an effective teaching strategy in psychology and other disciplines. In the present investigation, I build on my earlier, exploratory success with CBI in introductory psychology (Mayo, 2002) by implementing this approach in teaching psychology of adjustment, where actual case studies can be readily employed to illustrate how course content relates to real-life scenarios. Intact classes were randomly assigned to receive CBI involving a collaborative component or traditional instruction alone (control). The results of objective testing indicate that students exposed to CBI outperformed those in the control on comprehension and application of course principles. Engaging class discussions provided evidence of varied conceptual applications by students. Based on questionnaire findings, students viewed CRE as challenging, interesting, realistic, and helpful toward learning. Viewing the present findings in tandem with those of related reports on the effectiveness of CBI, there is a growing body of evidence in support of CBI as a useful instructional tool in the undergraduate curriculum. Results are discussed in terms of cognitive and social constructivism. Implications for future classroom research and practice are also presented.

The transformation of smallholder farming is poised to be one of the key drivers of achieving the dual objectives of food security and poverty reduction in Sub-Saharan Africa (SSA). Smallholder farmers account for between 60–80% of the food produced in the region but face many challenges that impede their productivity. Such challenges include a lack of timely access to appropriate agricultural information and services, which results in poor decision-making, particularly in addressing challenges and responding effectively to opportunities. In that context, the effective use of Information and Communication Technologies (ICTs) in improving accessibility to appropriate agricultural information and services presents substantial prospects for transforming the productivity and livelihoods of the farmers. Currently, the region experiences massive penetration and propagation of mobile and web-based applications. However, there is a dearth of compelling, comprehensive reviews evaluating their importance in enhancing agricultural information and services dissemination to smallholder farmers. Therefore, the current review explores the potential of enhancing agricultural information and services dissemination to smallholder farmers through ICTs and highlights gaps in their development and deployment in SSA. Five existing mobile applications used to disseminate agricultural information and services to smallholder farmers were identified, and their advantages, limitations, and opportunities were discussed. These were Esoko, iCow, Community Knowledge Workers, WeFarm and DigiFarm. The development and deployment of user-driven mobile applications that provide curated skill-sharing platforms, encourage farmers to give feedback to extension systems in real-time and promote the participation of women and youth in agriculture are recommended.

Abstract The radiant energy budget and internal heat are fundamental properties of giant planets, but precise determination of these properties remains a challenge. Here, we report measurements of Jupiter’s radiant energy budget and internal heat based on Cassini multi-instrument observations. Our findings reveal that Jupiter’s Bond albedo and internal heat, 0.503 ± 0.012 and 7.485 ± 0.160 W m −2 respectively, are significantly larger than 0.343 ± 0.032 and 5.444 ± 0.425 Wm −2 , the previous best estimates. The new results help constrain and improve the current evolutionary theories and models for Jupiter. Furthermore, the significant wavelength dependency of Jupiter’s albedo implies that the radiant energy budgets and internal heat of the other giant planets in our solar system should be re-examined. Finally, the data sets of Jupiter’s characteristics of reflective solar spectral irradiance provide an observational basis for the models of giant exoplanets.

Emerging infectious diseases are a significant threat to global biodiversity. While historically overlooked, a group of iridoviruses in the genus Ranavirus has been responsible for die-offs in captive and wild amphibian, reptile and fish populations around the globe over the past two decades. In order to share contemporary information on ranaviruses and identify critical research directions, the First International Symposium on Ranaviruses was held in July 2011 in Minneapolis, MN, USA. Twenty-three scientists and veterinarians from nine countries examined the ecology and evolution of ranavirus-host interactions, potential reservoirs, transmission dynamics, as well as immunological and histopathological responses to infection. In addition, speakers discussed possible mechanisms for die-offs, and conservation strategies to control outbreaks.

This paper sheds light on the reasons for the limited uptake of responsible tourism initiative memberships by hotels in South Africa, despite South Africa being regarded as a leader in the field of responsible tourism policy, with the drafting of responsible tourism guidelines by the South African Department of Environmental Affairs and Tourism (DEAT). The International Centre for Responsible Tourism’s conference (hosted in South Africa) preceding the World Summit on Sustainable Development in 2002 resulted in the Cape Town Declaration, which was based on the guidelines developed by DEAT. There are currently two responsible tourism membership initiatives in South Africa. Non-experimental survey research was conducted among hotels about their understanding and implementation of responsible tourism practices. Sixty hotels responded to the survey, and it would appear that these hotels implement Corporate Social Responsibility/responsible tourism, though to varying extents. Many responding hotels do not participate in responsible tourism initiatives because of - amongst others - confusion about what the concept means, and a lack of awareness of such initiatives. This paper raises questions about the effectiveness of membership initiatives in promoting the implementation of responsible tourism practices and questions the importance of a common understanding and awareness of what responsible tourism entails in ensuring that policy is implemented.

A virtual instrument is composed of some specialized subunits, some general-purpose computers, some software, and a little know-how. The instrument no longer has to be in one box. Virtual instruments can be simple or very complex. Understanding the real field of virtual instrumentation is just beginning. Over the next few years, there will be a rash of subunits specifically designed for the virtual instrumentation market. These will provide the building blocks for the next generation of field instrumentation and measurement.

Orientation: The influence of flexible work arrangements (FWAs) on employee engagement. Research purpose: This research was conducted to explore the influence of FWAs on employee engagement in order to gain a richer understanding than what is offered in pre-existing literature, and to provide practical recommendations to practitioners through a proposed framework. Motivation for the study: Flexible work arrangements are becoming increasingly popular management practices within the business landscape. Significant research has been conducted to understand the influence of FWAs on various employee engagement constructs; however, these findings still show considerable variations and are highly inconsistent. Research approach/design and method: This study used a qualitative mono method to explore the influence of FWAs on employee engagement. Qualitative, exploratory data allowed the researchers to gain new insights. A total of 23 semi-structured, face-to-face interviews were conducted. Respondents comprised eight subject matter experts and 15 employees from six different organisations, across six different industries. Interviews were analysed using a thematic analysis approach. Main findings: This study found a positive relationship between FWAs and employee engagement. It also revealed that FWAs were positively associated with various employee engagement constructs found in the literature, with the most prominent finding showing positive influence of FWAs on employee well-being. Practical/managerial implications: This study further developed a proposed framework for the successful implementation of FWAs to improve employee engagement. Contribution/value-add: This study offers theoretical, methodological and practical implications for employee engagement and human resource development scholars and practitioners motivated to find ways to better manage FWAs and improve employee engagement.

This study examines the relationship between assessments of the risk of punishment and self‐reported involvement in three illegal behaviors in a sample of college‐aged respondents. It is found that those respondents who had not yet committed a particular offense were more likely to perceive a greater certainty of punishment than those with experience in committing the offense. For two of three offenses the effect of becoming involved in offending had a more substantial impact on the perceptions of those respondents with both experience in offending and high perceived certainty of punishment than on those who had experience and less pessimistic estimates of risk Finally, a multivariate analysis of the relationship between behavioral and perceptual change reveals that each variable affects the other even when other sources of change are controlled. The importance of the findings for the deterrence doctrine are discussed.

Mammalian embryonic stem (ES) cells can either self-renew or generate progenitor cells that have a more restricted developmental potential.This provides an important model system to ask how pluripotency, cell commitment and differentiation are regulated at the level of chromatin-based changes that distinguish stem cells from their differentiated progeny.Here we show that the differentiation of ES cells to neural progenitors results in dynamic changes in the epigenetic status of multiple genes that encode transcription factors critical for early embryonic development or lineage specification.In particular, we demonstrate that DNA replication at a subset of neural-associated genes including Pax3, Pax6, Irx3, Nkx2.9 and Mash1 is advanced upon neural induction, consistent with increased locus accessibility.Conversely, many ES-associated genes including Oct4, Nanog, Utf1, Foxd3, Cripto and Rex1 that replicate early in ES cells switch their replication timing to later in S-phase in response to differentiation.Detailed analysis of the Rex1 locus reveals that delayed replication extends to a 2.8 Mb region surrounding the gene and is associated with substantial reductions in the level of histone H3K9 and H4 acetylation at the promoter.These results show that loss of pluripotency (and lineage choice) is associated with extensive and predictable changes in the replication timing of key regulator genes.

A national survey was conducted to determine the information technology skills nurse administrators consider critical for new nurses entering the work force. The sample consisted of 2,000 randomly selected members of the American Organization of Nurse Executives. Seven hundred fifty-two usable questionnaires were returned, for a response rate of 38%. The questionnaire used a 5-point Likert scale and consisted of 17 items that assessed various technology skills and demographic information. The questionnaire was developed and pilot tested with content experts to establish content validity. Descriptive analysis of the data revealed that using e-mail effectively, operating basic Windows applications, and searching databases were critical information technology skills. The most critical information technology skill involved knowing nursing-specific software, such as bedside charting and computer-activated medication dispensers. To effectively prepare nursing students with technology skills needed at the time of entry into practice, nursing faculty need to incorporate information technology skills into undergraduate nursing curricula.
