Parental influences are among the strongest behavioral correlates to unintentional injury outcome in early childhood, but are less well understood as children develop. We implemented a prospective research design to study how parenting style, parent-child relationships, and parental mental health influence injury during middle childhood. We also considered the roles of parent and child gender. Parental influences were assessed from a sample of 584 first graders, plus their mothers and fathers. Injuries requiring medical treatment were assessed regularly over the subsequent 5 years. Logistic regression models examined how maternal and paternal parenting factors predicted injury among all children, just boys, and just girls. Fathers who reported more positive relationships with their children had children protected from injury. This was particularly true of father-son relationships. No maternal traits predicted injury. A positive father-child, and especially a positive father-son relationship, may protect children from injury during middle childhood.

Previous evidence suggests that a significant decline in cognitive ability begins during middle-age and continues to deteriorate with increase in age. Recent work has demonstrated the potential rejuvenation impact of growth differentiation factor-11 (GDF-11) in aged mice. We carried out experiments to evaluate the impact of a single dose of recombinant (rGDF-11) on short-term visual and spatial memory in middle-aged male mice. On the novel object recognition task, we observed middle-aged mice treated rGDF-11 showed improved performance on the novel object recognition task. However, middle-aged mice did not show increased expression of phosphorylated-Smad2/3, a downstream effector of GDF-11. We noted however that the expression of the transcription factor, Sox2 was increased within the dentate gyrus. Our data suggest that a single injection of rGDF-11 contributes to improvements in cognitive function of middle-aged animals, which may be critical in the preservation of short-term memory capacity in old age.

Emergency department (ED) nurses suffer from persistent stress after experiencing the traumatic event of exposure to Middle East respiratory syndrome coronavirus (MERS-CoV), which can subsequently lead to burnout. This study aimed to assess ED nurses' burnout level during an outbreak of MERS-CoV and to identify influencing factors in order to provide basic information for lowering and preventing the level of burnout. Study participants were ED nurses working in eight hospitals designated for treating MERS-CoV-infected patients in Korea. We performed multiple regression analysis to explore the factors influencing burnout. The ED nurses' burnout was affected by job stress (β=0.59, p<.001), poor hospital resources for the treatment of MERS-CoV (β = -0.19, p<.001) and poor support from family and friends (β = -0.14, p<.05). These three variables explained 47.3% of the variance in burnout. ED nurses taking care of MERS-CoV-infected patients should be aware that burnout is higher for nurses in their divisions than nurses in other hospital departments and that job stress is the biggest influential factor of burnout. To be ready for the outbreak of emerging contagious diseases such as MERS-CoV, efforts and preparations should be made to reduce burnout. Job stress should be managed and resolved. Working conditions for mitigating job stress and systematic stress management programs should be provided, and hospital resources for the treatment of MERS-CoV need to be reinforced. Moreover, promoting support from family and friends is required. Copyright © 2016. Published by Elsevier B.V.

10 learn about the neglected conditions and intuence factors of middle school students aged 12 to 17 years old in rural areas of Shaanxi Province and Chongqing City. The scale and evaluation method formulated in "The Normal Value of Evaluation on the Neglect of Middle School Students from 12 to 17 Years Old in Rural China" was adopted. 2257 respondents among which there were 1157 male students and 1,100 female students in the rural areas of Shaanxi Province and Chongqing City were selected according to the principle of multi-stage stratified cluster sampling. The severe degree of neglect was reflected through the indicator of neglect degree. The method of binary Logistic regression analysis was adopted to analyze the influence factors of neglect. Results The total neglect degree of respondents was (51. 80 ± 9. 06). The neglect degree of middle school students in the rural areas of Chongqing was (53. 21 ± 9. 03). The neglect degree of middle school students in the rural areas of Shaanxi was 50. 50 8. 90. The statistical significance was found in the difference between the two groups (U =6. 17, P <0. 01). The neglect degree of male students was (51. 93 ± 8. 67) while the neglect degree of female students was (51. 66 ± 9. 46). The statistical significance was not found in the difference between the two groups of total neglect degree of different sexes (U = 0. 60, P > 0. 05). The statistical significance was noticed in the differences of neglect degrees of middle school students in different grades at all levels (P <0. 05). The neglect degrees of junior three and senior three students were relatively high. Their total neglect degrees were (53. 54 ± 9. 70) and (53. 36 ± 8. 69) respectively. Except social neglect and safety neglect, there was statistical significance in the differences of neglect degrees of students with different family backgrounds at all levels (P <0. 01).

Community health workers (CHWs) are increasingly recognized as an integral component of the health workforce needed to achieve public health goals in low- and middle-income countries (LMICs). Many factors influence CHW performance. A systematic review was conducted to identify intervention design related factors influencing performance of CHWs. We systematically searched six databases for quantitative and qualitative studies that included CHWs working in promotional, preventive or curative primary health services in LMICs. One hundred and forty studies met the inclusion criteria, were quality assessed and double read to extract data relevant to the design of CHW programmes. A preliminary framework containing factors influencing CHW performance and characteristics of CHW performance (such as motivation and competencies) guided the literature search and review. A mix of financial and non-financial incentives, predictable for the CHWs, was found to be an effective strategy to enhance performance, especially of those CHWs with multiple tasks. Performance-based financial incentives sometimes resulted in neglect of unpaid tasks. Intervention designs which involved frequent supervision and continuous training led to better CHW performance in certain settings. Supervision and training were often mentioned as facilitating factors, but few studies tested which approach worked best or how these were best implemented. Embedment of CHWs in community and health systems was found to diminish workload and increase CHW credibility. Clearly defined CHW roles and introduction of clear processes for communication among different levels of the health system could strengthen CHW performance.

While both environmental and genetic factors are important in the etiology of psychoactive substance use (PSU), we know little of how these influences differ through development. To clarify the changing role of genes and environment in PSU from early adolescence through middle adulthood. Retrospective assessment by life history calendar, with univariate and bivariate structural modeling. General community. A total of 1796 members of male-male pairs from the Virginia Adult Twin Study of Psychiatric and Substance Use Disorders. Levels of use of alcohol, caffeine, cannabis, and nicotine recorded for every year of the respondent's life. For nicotine, alcohol, and cannabis, familial environmental factors were critical in influencing use in early adolescence and gradually declined in importance through young adulthood. Genetic factors, by contrast, had little or no influence on PSU in early adolescence and gradually increased in their effect with increasing age. The sources of individual differences in caffeine use changed much more modestly over time. Substantial correlations were seen among levels of cannabis, nicotine, and alcohol use and specifically between caffeine and nicotine. In adolescence, those correlations were strongly influenced by shared effects from the familial environment. However, as individuals aged, more and more of the correlation in PSU resulted from genetic factors that influenced use of both substances. These results support an etiologic model for individual differences in PSU in which initiation and early patterns of use are strongly influenced by social and familial environmental factors while later levels of use are strongly influenced by genetic factors. The substantial correlations seen in levels of PSU across substances are largely the result of social environmental factors in adolescence, with genetic factors becoming progressively more important through early and middle adulthood.

Whenever there has been a worldwide contagious disease outbreak, there have been reports of infection and death of healthcare workers. Particularly because emergency nurses have contact with patients on the front line, they experience ethical problems in nursing while struggling with infectious diseases in an unfavorable environment. The objective of this study was to explore emergency nurses' ethical problems and to identify factors influencing these problems during the outbreak of Middle East respiratory syndrome-coronavirus in Korea. For this cross-sectional study, a questionnaire survey was conducted with emergency nurses working in six hospitals selected through convenience sampling from the hospitals designated for Middle East respiratory syndrome-coronavirus patients in the capital area. Data were collected from 169 emergency nurses in Korea during August 2015. Ethical considerations: This research was approved by the Institutional Review Board of G University in Korea. The findings of this study suggest that during the Middle East respiratory syndrome-coronavirus outbreak, emergency nurses experienced ethical problems tied to a mind-set of avoiding patients. Three factors were found to influence emergency nurses' ethical problems (in order of influence): cognition of social stigmatization, level of agreement with infection control measures, and perceived risk. Through this study, we obtained information on emergency nurses' ethical problems during the Middle East respiratory syndrome-coronavirus outbreak and identified the factors that influence them. As found in this study, nurses' ethical problems were influenced most by cognitions of social stigmatization. Accordingly, to support nurses confidently care for people during future health disasters, it is most urgent to promote appropriate public consciousness that encourages healthcare workers.

Household burning of solid fuels in traditional stoves is detrimental to health, the environment and development. A range of improved solid fuel stoves (IS) are available but little is known about successful approaches to dissemination. This qualitative systematic review aimed to identify factors that influence household uptake of IS in low- and middle-income countries. Extensive searches were carried out and studies were screened and extracted using established systematic review methods. Fourteen qualitative studies from Asia, Africa and Latin-America met the inclusion criteria. Thematic synthesis was used to synthesise data and findings are presented under seven framework domains. Findings relate to user and stakeholder perceptions and highlight the importance of cost, good stove design, fuel and time savings, health benefits, being able to cook traditional dishes and cleanliness in relation to uptake. Creating demand, appropriate approaches to business, and community involvement, are also discussed. Achieving and sustaining uptake is complex and requires consideration of a broad range of factors, which operate at household, community, regional and national levels. Initiatives aimed at IS scale up should include quantitative evaluations of effectiveness, supplemented with qualitative studies to assess factors affecting uptake, with an equity focus.

Poor sleep quality is a risk factor for a number of cognitive and physiological age-related disorders. Identifying factors underlying sleep quality are important in understanding the etiology of these age-related health disorders. We investigated the extent to which genes and the environment contribute to subjective sleep quality in middle-aged male twins using the classical twin design. We used the Pittsburgh Sleep Quality Index to measure sleep quality in 1218 middle-aged twin men from the Vietnam Era Twin Study of Aging (mean age = 55.4 years; range 51-60; 339 monozygotic twin pairs, 257 dizygotic twin pairs, 26 unpaired twins). The mean PSQI global score was 5.6 [SD = 3.6; range 0-20]. Based on univariate twin models, 34% of variability in the global PSQI score was due to additive genetic effects (heritability) and 66% was attributed to individual-specific environmental factors. Common environment did not contribute to the variability. Similarly, the heritability of poor sleep-a dichotomous measure based on the cut-off of global PSQI>5-was 31%, with no contribution of the common environment. Heritability of six of the seven PSQI component scores (subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, and daytime dysfunction) ranged from 0.15 to 0.31, whereas no genetic influences contributed to the use of sleeping medication. Additive genetic influences contribute to approximately one-third of the variability of global subjective sleep quality. Our results in middle-aged men constitute a first step towards examination of the genetic relationship between sleep and other facets of aging. © 2013 European Sleep Research Society.

This study was performed to identify the influencing factors on alienation among high school students. Data was collected by questionnaires from 550 students of academic and vocational high schools in G city. The data was analyzed using descriptive statistics, pearson correlation coefficients, and stepwise multiple regression. The scores of alienation among students in financially lower middle class and lower class were higher than those of the upper middle class students, resulting in significant differences(F=6.87, p=.00). A sense of alienation showed a significantly negative correlation with the scores of responding parenting style(r=-.32), family cohesion(r=-.33), school attachment(r=-.51), academic performance(r=-.34), peer relationships(r=-.38), self-control (r=-.43), and social skills(r=-.33). The most powerful predictor of alienation among high school students was school attachment and the variance explained was 26%. A combination of school attachment, self control, peer relationships, family cohesion, demanding parenting style, and academic performance account for 40% of the variance in alienation among high school students. This study suggests that school attachment, self control, peer relationships, family cohesion, demanding parenting style, and academic performance are significant influencing factors on alienation in high school students. Therefore, nursing strategy is needed to manage these revealed factors.

Adolescent mothers aged 15-19 years are known to have greater risks of maternal morbidity and mortality compared with women aged 20-24 years, mostly due to their unique biological, sociological and economic status. Nowhere Is the burden of disease greater than in low-and middle-income countries (LMICs). Understanding factors that influence adolescent utilisation of essential maternal health services (MHS) would be critical in improving their outcomes. We systematically reviewed the literature for articles published until December 2015 to understand how adolescent MHS utilisation has been assessed in LMICs and factors affecting service utilisation by adolescent mothers. Following data extraction, we reported on the geographical distribution and characteristics of the included studies and used thematic summaries to summarise our key findings across three key themes: factors affecting MHS utilisation considered by researcher(s), factors assessed as statistically significant, and other findings on MHS utilisation. Our findings show that there has been minimal research in this study area. 14 studies, adjudged as medium to high quality met our inclusion criteria. Studies have been published in many LMICs, with the first published in 2006. Thirteen studies used secondary data for assessment, data which was more than 5 years old at time of analysis. Ten studies included only married adolescent mothers. While factors such as wealth quintile, media exposure and rural/urban residence were commonly adjudged as significant, education of the adolescent mother and her partner were the commonest significant factors that influenced MHS utilisation. Use of antenatal care also predicted use of skilled birth attendance and use of both predicted use of postnatal care. However, there may be some context-specific factors that need to be considered. Our findings strengthen the need to lay emphasis on improving girl child education and removing financial barriers to their access to MHS

Early childhood risk and resilience factors for behavioural and emotional problems in middle childhood.

Mental disorders in childhood have a considerable health and societal impact but the associated negative consequences may be ameliorated through early identification of risk and protective factors that can guide health promoting and preventive interventions. The objective of this study was to inform health policy and practice through identification of demographic, familial and environmental factors associated with emotional or behavioural problems in middle childhood, and the predictors of resilience in the presence of identified risk factors. A cohort of 706 mothers followed from early pregnancy was surveyed at six to eight years post-partum by a mail-out questionnaire, which included questions on demographics, children's health, development, activities, media and technology, family, friends, community, school life, and mother's health. Although most children do well in middle childhood, of 450 respondents (64% response rate), 29.5% and 25.6% of children were found to have internalising and externalising behaviour problem scores in the lowest quintile on the NSCLY Child Behaviour Scales. Independent predictors for problem behaviours identified through multivariable logistic regression modelling included being male, demographic risk, maternal mental health risk, poor parenting interactions, and low parenting morale. Among children at high risk for behaviour problems, protective factors included high maternal and child self-esteem, good maternal emotional health, adequate social support, good academic performance, and adequate quality parenting time. These findings demonstrate that several individual and social resilience factors can counter the influence of early adversities on the likelihood of developing problem behaviours in middle childhood, thus informing enhanced public health interventions for this understudied life course phase.

Risk factors for suicidal ideation in Korean middle-aged adults: the role of socio-demographic status.

The investigations of the risk factors for suicidal ideation among middle-aged adults may be especially important for predicting suicidal actions, given the steep increase in suicide among Koreans aged 45-54. Few studies have sought to investigate the effect of socio-demographic status on suicidal ideation among middle-aged adults. This study investigated the influence of socio-demographic status on suicidal ideation among middle-aged adults in South Korea. The sample consisted of middle-aged men (n = 3,214) and middle-aged women (n = 4,087) aged 40-64 years who had participated in the 2005 cross-sectional Seoul Citizens Health and Social Indicators Survey. Using multiple logistic regression analysis, we examined the effect of socio-demographic status, health behaviours and health status on suicidal ideation in middle-aged adults. The outstanding finding was that suicidal ideation was most prevalent among middle-aged women who engaged in manual labour (i.e. blue-collar workers) (OR = 2.77, 95% CI = 1.20-6.42). The absence of a spouse was significantly associated with suicidal ideation among middle-aged men (OR = 2.10, 95% CI = 1.30-3.40). The effect of enhanced security related to stable employment was strongest among middle-aged women in blue-collar jobs, and the effect of intensive counselling services was strongest among divorced or widowed middle-aged men.

Influence of school-level variables on aggression and associated attitudes of middle school students.

2011-10-01

This study sought to understand school-level influences on aggressive behavior and related social cognitive variables. Participants were 5106 middle school students participating in a violence prevention project. Predictors were school-level norms opposing aggression and favoring nonviolence, interpersonal climate (positive student-teacher relationships and positive student-student relationships), and school responsiveness to violence (awareness and reporting of violence and school safety problems). Outcomes were individual-level physical aggression, beliefs supporting aggression, and self-efficacy for nonviolent responses. School norms and both interpersonal climate variables had effects on all three outcomes in theorized directions. Only one of the responsiveness measures, awareness and reporting of violence, had theoretically consistent effects on all outcomes. The other, school safety problems, affected self-efficacy later in middle school. Evidence of gender moderation was generally consistent with greater influence of school-level factors on female adolescents. Discussion focuses on implications in light of previous research and intervention possibilities. Copyright © 2011 Society for the Study of School Psychology. Published by Elsevier Ltd.

Episodic memory is a complex construct at both the phenotypic and genetic level. Ample evidence supports age-related cognitive stability and change being accounted for by general and domain-specific factors. We hypothesized that general and specific factors would underlie change even within this single cognitive domain. We examined six measures from three episodic memory tests in a narrow age cohort at middle and late middle age. The factor structure was invariant across occasions. At both timepoints two of three test-specific factors (story recall, design recall) had significant genetic influences independent of the general memory factor. Phenotypic stability was moderate to high, and primarily accounted for by genetic influences, except for one test-specific factor (list learning). Mean change over time was nonsignificant for one test-level factor; one declined; one improved. The results highlight the phenotypic and genetic complexity of memory and memory change, and shed light on an understudied period of life. PMID:25938244

Ample evidence supports age-related cognitive stability and change being accounted for by general and domain-specific factors. We hypothesized that general and specific factors would underlie change even within this single cognitive domain. We examined 6 measures from 3 episodic memory tests in a narrow age cohort at middle and late middle age. The factor structure was invariant across occasions. At both timepoints 2 of 3 test-specific factors (story recall, design recall) had significant genetic influences independent of the general memory factor. Phenotypic stability was moderate to high, and primarily accounted for by genetic influences, except for 1 test-specific factor (list learning). Mean change over time was nonsignificant for 1 test-level factor; 1 declined; 1 improved. The results highlight the phenotypic and genetic complexity of memory and memory change, and shed light on an understudied period of life. (c) 2015 APA, all rights reserved.

The Han River basin is one of the most important industrial and grain production bases in the central China. A lot of factories and towns have been established along the river where large farmlands are located nearby. In the last few decades the water quality of the Han River, specifically in middle and lower reaches, has gradually declined. The agricultural nonpoint pollution and municipal and industrial point pollution significantly degrade the water quality of the Han River. Factor analysis can be applied to reduce the dimensionality of a data set consisting of a large number of inter-related variables. Cluster analysis can classify the samples according to their similar characters. In this study, factor analysis is used to identify major pollution indicators, and cluster analysis is employed to classify the samples based on the sample locations and hydrochemical variables. Water samples were collected from 12 sample sites collected from Xiangyang City (middle Han River) to Wuhan City (lower Han River). Correlations among 25 hydrochemical variables are statistically examined. The important pollutants are determined by factor analysis. A three-factor model is determined and explains over 85% of the total river water quality variation. Factor 1, including SS, Chl-a, TN and TP, can be considered as the nonpoint source pollution. Factor 2, including Cl-, Br-, SO42-, Ca2+, Mg2+, K+, Fe2+ and PO43-, can be treated as the industrial pollutant pollution. Factor 3, including F- and NO3-, reflects the influence of the groundwater or self-purification capability of the river water. The various land uses along the Han River correlate well with the pollution types. In addition, the result showed that the water quality of Han River deteriorated gradually from middle to lower Han River. Some tributaries have been seriously polluted and significantly influence the mainstream water quality of the Han River. Finally, the result showed that the nonpoint pollution and the point

Fast food is popular among children and adolescents; however, its consumption has often been associated with negative impacts on nutrition and health. This study examined current fast food consumption status among middle school students and explored factors influencing fast food consumption by applying Theory of Planned Behavior. A total of 354 (52.5% boys) students were recruited from a middle school. The subjects completed a pre-tested questionnaire. The average monthly frequency of fast food consumption was 4.05 (4.25 for boys, 3.83 for girls). As expected, fast food consumption was considered to be a special event rather than part of an everyday diet, closely associated with meeting friends or celebrating, most likely with friends, special days. The Theory of Planned Behavior effectively explained fast food consumption behaviors with relatively high R(2) around 0.6. Multiple regression analyses showed that fast food consumption behavior was significantly related to behavioral intention (b = 0.61, P < 0.001) and perceived behavioral control (b = 0.19, P < 0.001). Further analysis showed that behavioral intention was significantly related to subjective norm (b = 0.15, P < 0.01) and perceived behavioral control (b = 0.56, P < 0.001). Attitude toward fast food consumption was not significantly associated with behavioral intention. Therefore, effective nutrition education programs on fast food consumption should include components to change the subjective norms of fast food consumption, especially among peers, and perceived behavioral control. Further studies should examine effective ways of changing subjective norms and possible alternatives to fast food consumption for students to alter perceived behavioral control.

Interracial relationships in Canada have increased over the years. However, little research has focused on comparing STI/HIV risk and condom use between those in intra- and interracial relationships, specifically among Middle Eastern-Canadians. A web-based survey was administered to Middle Eastern-Canadians. Logistic regression analysis was used to assess factors associated with consistent condom use. Analyses were stratified by partner's race (Middle Eastern or non-Middle Eastern). The analysis sub-sample consisted of 92 participants. Factors associated with consistent condom use varied between the stratified groups. Among those with Middle Eastern partners, attitude towards marriage and the family and control in the relationship were associated with condom use. Among participants with non-Middle Eastern partners, acculturation and HIV knowledge were found to be associated with condom use. Factors associated with condom use varied between Middle Eastern-Canadians in intra- and interracial relationships. These differences illustrate the need for tailored interventions aimed at increasing condom use among this racial group.

Understanding middle managers' influence in implementing patient safety culture.

PubMed

Gutberg, Jennifer; Berta, Whitney

2017-08-22

The past fifteen years have been marked by large-scale change efforts undertaken by healthcare organizations to improve patient safety and patient-centered care. Despite substantial investment of effort and resources, many of these large-scale or "radical change" initiatives, like those in other industries, have enjoyed limited success - with practice and behavioural changes neither fully adopted nor ultimately sustained - which has in large part been ascribed to inadequate implementation efforts. Culture change to "patient safety culture" (PSC) is among these radical change initiatives, where results to date have been mixed at best. This paper responds to calls for research that focus on explicating factors that affect efforts to implement radical change in healthcare contexts, and focuses on PSC as the radical change implementation. Specifically, this paper offers a novel conceptual model based on Organizational Learning Theory to explain the ability of middle managers in healthcare organizations to influence patient safety culture change. We propose that middle managers can capitalize on their unique position between upper and lower levels in the organization and engage in 'ambidextrous' learning that is critical to implementing and sustaining radical change. This organizational learning perspective offers an innovative way of framing the mid-level managers' role, through both explorative and exploitative activities, which further considers the necessary organizational context in which they operate.

Factors that influence the provision of intrapartum and postnatal care by skilled birth attendants in low- and middle-income countries: a qualitative evidence synthesis

Background In many low- and middle-income countries women are encouraged to give birth in clinics and hospitals so that they can receive care from skilled birth attendants. A skilled birth attendant (SBA) is a health worker such as a midwife, doctor, or nurse who is trained to manage normal pregnancy and childbirth. (S)he is also trained to identify, manage, and refer any health problems that arise for mother and baby. The skills, attitudes and behaviour of SBAs, and the extent to which they work in an enabling working environment, impact on the quality of care provided. If any of these factors are missing, mothers and babies are likely to receive suboptimal care. Objectives To explore the views, experiences, and behaviours of skilled birth attendants and those who support them; to identify factors that influence the delivery of intrapartum and postnatal care in low- and middle-income countries; and to explore the extent to which these factors were reflected in intervention studies. Search methods Our search strategies specified key and free text terms related to the perinatal period, and the health provider, and included methodological filters for qualitative evidence syntheses and for low- and middle-income countries. We searched MEDLINE, OvidSP (searched 21 November 2016), Embase, OvidSP (searched 28 November 2016), PsycINFO, OvidSP (searched 30 November 2016), POPLINE, K4Health (searched 30 November 2016), CINAHL, EBSCOhost (searched 30 November 2016), ProQuest Dissertations and Theses (searched 15 August 2013), Web of Science (searched 1 December 2016), World Health Organization Reproductive Health Library (searched 16 August 2013), and World Health Organization Global Health Library for WHO databases (searched 1 December 2016).

Differences in socioeconomic status (SES) such as income levels may partly explain why breast cancer screening (BCS) disparities exist in countries where health care services are free or heavily subsidized. However, factors that contribute to such differences in SES among women living in well resourced Middle East countries are not fully understood. This quantitative study investigated factors that influence SES and BCS of Arab women. Understanding of such factors can be useful for the development of effective intervention strategies that aim to increase BCS uptake among Arab women. Using data from a cross-sectional survey among 1,063 Arabic-speaking women in Qatar, age 35+, additional data analysis was performed to determine the relationship between socioeconomic indicators such as income and other factors in relation to BCS activities. This study found that income is determined and influenced by education level, occupation, nationality, years of residence in the country, level of social activity, self-perceived health status, and living area. Financial stress, unemployment, and unfavorable social conditions may impede women's participation in BCS activities in well resourced Middle East countries.

[Factors Related to Presenteeism in Young and Middle-aged Nurses].

PubMed

Yoshida, Mami; Miki, Akiko

2018-04-03

Presenteeism is considered to be not only a work-related stressor but also a factor involved in the development of workaholism and error proneness, which is often described as careless. Additionally, increasing health issues arising from aging suggest the possibility that presenteeism in middle-aged nurses is different than that in young ones. Therefore, the present study aimed to identify and tease apart factors involved in presenteeism among young and middle-aged nurses. An anonymous self-administered questionnaire survey was conducted among 2,006 nurses working at 10 hospitals. In total, 761 nurses aged <40 years and 536 nurses aged ≥40 years were enrolled in this study. Work Impairment Scores (WIS) on the Japanese version of the Stanford Presenteeism Scale were measured for presenteeism. Job stressors, workaholism, and error proneness were measured for related factors. Multiple regression analysis was conducted after determining the WIS as the dependent variable and related factors as independent variables. Overall, 70.8% of the young nurses reported health problems compared to 82.5% of the middle-aged nurses. However, WIS in young nurses was significantly higher than that in middle-aged ones (p < 0.001). WIS in young nurses showed a significant relationship with the degree of stressors, "difficulty of work" (β = 0.28, p < 0.001) and tendency to "work excessively" (β = 0.18, p < 0.001), which is a subscale of workaholism, error proneness of "action slips" (β = 0.14, p < 0.01) and "cognitive narrowing" (β = 0.11, p < 0.05). Conversely, WIS in middle-aged nurses showed a significant relationship with "cognitive narrowing" (β = 0.29, p < 0.001) and to "work excessively" (β = 0.17, p < 0.001), the degree of stressors on "difficulty of work" (β = 0.12, p < 0.05) and "lack of communication" (β = 0.13, p < 0.01). It was clarified that the increased health problems of middle-aged nurses does not necessarily lower their working capacity. Also, compared to

In the previous article, we calculated dentist service rates for 200 general dentists based on a homogeneous, well-educated, upper-middle-class population of patients. Wide variations in the rates were detected. In this analysis, factors influencing variation in the rates were identified. Variation in rates for categories of dental services was explained by practice characteristics, patient exposure to fluoridated water supplies, and non-price competition in the dental market. Rates were greatest in large, busy practices in markets with high fees. Older practices consistently had lower rates across services. As a whole, these variables explained between 5 and 30 percent of the variation in the rates.

Comprehensive research for factors related to healthy lifestyles of the elderly is limited. The present study aimed to elucidate the factors associated with adherence to a healthy lifestyle by age groups. The present study was based on data from the 2005 Korea National Health and Nutrition Examination Survey. We calculated crude proportions and adjusted proportions of cigarette smokers, problem alcohol drinkers, and physically inactive people in two age groups (40-59 years and ≥60 years). We carried out multilevel analysis to elucidate factors associated with healthy lifestyles. Of 3194 respondents included in the analysis, 1154 (36.13%) were aged 60 years or older. Older participants smoked less (23.0% vs 17.4%) and exercised less frequently (52.4% vs 66.9%; all P < 0.001) than their middle-aged counterparts. After adjustment, the proportion of regular exercisers was inversed (adjusted proportion 0.468, 95% CI 0.436-0.501 vs 0.377, 95% CI 0.337-0.419, P = 0.004). In multilevel analysis, contextual factors, such as local tax per capita, was associated significantly with cigarette smoking only in the elderly (OR 1.037, 95% CI 1.005-1.070). Different factors were associated with healthy lifestyles of elderly people when compared with middle-aged people. In addition, local tax per capita, an area level variable, was more likely to be associated with smoking in the elderly than the middle-aged group. © 2014 Japan Geriatrics Society.

To investigate the prevalence of depressive symptom and its influencing factors among primary and middle school students in urban-rural-integrated area of Chongqing. A total of 3 013 primary and middle school students from an urban-rural-integrated area of Chongqing were selected by using multistage stratified cluster sampling method in this study. The general information, physical activities and physical examination conditions were investigated. Meanwhile, the depress symptoms were assessed by using children's depression inventory (CDI) and the incidence of adolescence related events were evaluated by using pubertal development scale (PDS). Chi-square test was used to analyze the detection rate of depression symptoms among different population and Logistic regression was used to analyse the influencing factors of depressive symptoms among primary and middle school students. The detection rate of depressive symptoms was 20.1% (607/3013) totally, and it was gradually higher among the students with bad to good economic status (28.3%/18.4%/18.3%, chi2 = 28.415, P < 0.05). The students' detection rate of depression symptoms in different development level compared to companion by self image were 43.1%, 26.5%, 22.0% and 15.8% (chi2 = 79.621, P < 0.01). Among the senior school students, worse economic status, higher development level in self-evaluation, and no physical activities in a recent month (including physical training, aerobic exercise) were considered as the influencing factors of depressive symptoms. Focusing on the physical and mental health of growing children, establishing a good school environment and family environment, and strengthening physical activities will contribute to reducing the incidence of depressive symptoms.

Leptospirosis outbreaks occur frequently in North and South Andaman Islands but not in Middle Andaman. In 2002, an outbreak appeared in Middle Andaman for the first time. Although a study on risk factors was conducted in North Andaman, it used seropositivity to define leptospirosis. Since seropositivity might not indicate current leptospiral infection and as no study on risk factors was conducted in Middle Andaman, we carried out this study to identify the risk factors during the outbreak. A suspected outbreak of leptospirosis occurred in Rangat of Middle Andaman during October - November 2002. Suspected cases were screened for leptospirosis using microscopic agglutination test (MAT). Fifty two patients confirmed to have leptospirosis based on rising titres in MAT on paired sera, and 104 age, sex and neighbourhood seronegative matched controls, were included in the study. A conditional multiple regression by backward elimination process was carried out with acute leptospirosis as the dependent factor and various environmental, occupational and behavioural factors as independent factors. A stratified analysis was also carried out. The presence of cattle in the house, drinking stream water, contact with garbage, walking barefoot and standing in water while working were identified as significant factors associated with leptospirosis. Stratified analysis showed a dose response relationship between number of cattle in the house and the risk of leptospiral infection suugesting that cattle could be a source of infection. Identification of the potential risk factors would help understand the transmission dynamics of the disease and formulate public health interventions.

Modeling social norms increasingly influences costly sharing in middle childhood.

PubMed

House, Bailey R; Tomasello, Michael

2018-07-01

Prosocial and normative behavior emerges in early childhood, but substantial changes in prosocial behavior in middle childhood may be due to it becoming integrated with children's understanding of what is normative. Here we show that information about what is normative begins influencing children's costly sharing in middle childhood in a sample of 6- to 11-year-old German children. Information about what is normative was most influential when indicating what was "right" (i.e., "The right thing is to choose this"). It was less influential when indicating what was prescribed by a rule (i.e., "There is a rule that says to choose this") or when it indicated what the majority of people do (i.e., "Most people choose this"). These findings support the idea that middle childhood is when social norms begin to shape children's costly sharing and provide insight into the psychological foundations of the relationship between norms and prosocial behavior.

Community health workers (CHWs) are increasingly recognized as an integral component of the health workforce needed to achieve public health goals in low- and middle-income countries (LMICs). Many factors intersect to influence CHW performance. A systematic review with a narrative analysis was conducted to identify contextual factors influencing performance of CHWs. We searched six databases for quantitative, qualitative, and mixed-methods studies that included CHWs working in promotional, preventive or curative primary health care services in LMICs. We differentiated CHW performance outcome measures at two levels: CHW level and end-user level. Ninety-four studies met the inclusion criteria and were double read to extract data relevant to the context of CHW programmes. Thematic coding was conducted and evidence on five main categories of contextual factors influencing CHW performance was synthesized. Few studies had the influence of contextual factors on CHW performance as their primary research focus. Contextual factors related to community (most prominently), economy, environment, and health system policy and practice were found to influence CHW performance. Socio-cultural factors (including gender norms and values and disease related stigma), safety and security and education and knowledge level of the target group were community factors that influenced CHW performance. Existence of a CHW policy, human resource policy legislation related to CHWs and political commitment were found to be influencing factors within the health system policy context. Health system practice factors included health service functionality, human resources provisions, level of decision-making, costs of health services, and the governance and coordination structure. All contextual factors can interact to shape CHW performance and affect the performance of CHW interventions or programmes. Research on CHW programmes often does not capture or explicitly discuss the context in which CHW

A Review of the Factors Associated With the Timely Initiation of Breastfeeding and Exclusive Breastfeeding in the Middle East

PubMed Central

Alzaheb, Riyadh A

2017-01-01

Background: Breastfeeding supplies all the nutrients that infants need for their healthy development. Breastfeeding practice is multifactorial, and numerous variables influence mothers’ decisions and ability to breastfeed. This review identifies the factors potentially affecting the timely initiation of breastfeeding within an hour after birth and exclusive breastfeeding in the first 6 months in Middle Eastern countries. Methods: The Medline, ScienceDirect, and Web of Science databases were keyword-searched for primary studies meeting the following inclusion criteria: (1) publication in the English language between January 2001 and May 2017, (2) original research articles reporting primary data on the factors influencing the timely initiation of breastfeeding and/or exclusive breastfeeding, (3) the use of World Health Organization definitions, and (4) Middle Eastern research contexts. A random effect model was used to establish the average prevalence of the timely initiation of breastfeeding and exclusive breastfeeding in the Middle East. Results: The review identified 19 studies conducted in Saudi Arabia (7), Iran (3), Egypt (2), Turkey (2), Kuwait (1), the United Arab Emirates (1), Qatar (1), Lebanon (1), and Syria (1). The meta-analysis established that 34.3% (confidence interval [CI]: 20.2%-51.9%) of Middle Eastern newborns received breastfeeding initiated within an hour of birth, and only 20.5% (CI: 14.5%-28.2%) were fed only breast milk for the first 6 months. The 8 studies exploring breastfeeding initiation most commonly associated it with the following: delivery mode, maternal employment, rooming-in, and prelacteal feeding. The 17 studies investigating exclusive breastfeeding most frequently linked it to the following: maternal age, maternal education, maternal employment, and delivery mode. Conclusions: Middle Eastern health care organizations should fully understand all the determinants of breastfeeding identified by this review to provide suitable

To investigate the distribution and main influential factors of mental workload of middle school teachers in Nanchang City. A total of 504 middle school teachers were sampled by random cluster sampling from middle schools in Nanchang City, and the mental workload level was assessed with National Aeronautics and Space Administration-Task Load Index (NASA-TLX) which was verified in reliability and validity. The mental workload scores of middle school teachers in Nanchang was approximately normal distribution. The mental workload level of middle school teachers aged 31 -35 years old was the highest. For those no more than 35 years old, there was positive correlation between mental workload and age (r = 0.146, P < 0.05). For those more than 35 years old, the levels of their mental workload had no statistically significant difference. There was a negative correlation between mental workload and educational level(r = -0.172, P < 0.05). The middle school teachers with lower educational level seemed to have a higher mental workload (P < 0.01). The longer a middle school teacher worked per day, the higher the mental workload was. Working hours per day was the most influential factor on mental workload in all influential factors (P < 0.001). Mental workload of middle school teachers was closely related to age, educational level and work hours per day. Working hours per day was the important risk factor of mental workload. Reducing working hours per day, especially reducing it to be no more than 8 hours per day, may be a significant and useful approach alleviating mental workload of middle school teachers in Nanchang City.

Antiretroviral medicines (ARVs) are one of the most costly parts of HIV/AIDS treatment. Many countries are struggling to provide universal access to ARVs for all people living with HIV and AIDS. Although substantial price reductions of ARVs have occurred, especially between 2002 and 2008, achieving sustainable access for the next several decades remains a major challenge for most low- and middle-income countries. The objectives of the present study were twofold: first, to analyze global ARV prices between 2005 and 2008 and associated factors, particularly procurement methods and key donor policies on ARV procurement efficiency; second, to discuss the options of procurement processes and policies that should be considered when implementing or reforming access to ARV programs. An ARV-medicines price-analysis was carried out using the Global Price Reporting Mechanism from the World Health Organization. For a selection of 12 ARVs, global median prices and price variation were calculated. Linear regression models for each ARV were used to identify factors that were associated with lower procurement prices. Logistic regression models were used to identify the characteristics of those countries which procure below the highest and lowest direct manufactured costs. Three key factors appear to have an influence on a country's ARV prices: (a) whether the product is generic or not; (b) the socioeconomic status of the country; (c) whether the country is a member of the Clinton HIV/AIDS Initiative. Factors which did not influence procurement below the highest direct manufactured costs were HIV prevalence, procurement volume, whether the country belongs to the least developed countries or a focus country of the United States President's Emergency Plan For AIDS Relief. One of the principal mechanisms that can help to lower prices for ARV over the next several decades is increasing procurement efficiency. Benchmarking prices could be one useful tool to achieve this.

Objectives The aims of this study were to determine the relative influence of genetic and environmental contributions to inflammatory biomarkers, and to what extent correlations among these markers are due to genetic or environmental factors. Methods We performed univariate and multivariate genetic analyses of four inflammatory markers: interleukin-6 (IL-6), soluble IL-6 receptor (sIL-6R), C-reactive protein (CRP), and fibrinogen, in 166 (88 monozygotic and 78 dizygotic) middle-aged male twin pairs. Results The mean age (±SD) of the twins was 54 (±2.93) years. Heritability was substantial for CRP (0.61, 95% CI: 0.47–0.72) and moderate to fair for IL-6 (0.31, 0.13–0.46), sIL-6R (0.49, 0.30–0.76) and fibrinogen (0.52, 0.34–0.65). IL-6, CRP and fibrinogen showed significant correlations, but not with sIL-6R. Multivariate genetic analysis found that these correlations could be best explained by a common pathway model, where the common factor explained 27%, 73% and 25% of the variance of IL-6, CRP and fibrinogen, respectively. About 46% (95% CI: 21–64%) of the correlations among the three inflammatory markers could be explained by the genetic factors. After adjusting for covariates known to influence inflammation levels, heritability estimates were slightly decreased but the overall results remained similar. Conclusions A significant part of the variation in inflammatory marker levels is due to genetic influences. Furthermore, almost 50% of the shared variance among these biomarkers is due to a common genetic factor which likely plays a key role in the regulation of inflammation. PMID:18243214

Adolescents observe and imitate people to whom they are associated in their social context, and the normative factors sent out by reference groups are crucial determinants of their decision to smoke. The aim of the study is to investigate how adolescents' smoking changes when they are exposed to factors of pro-smoking normative influence by parents and peers, and how age moderate this relation. A cross sectional survey collected data from 5657 students, aged between 11 and 14, from public and private middle schools in the Italian region of Switzerland (Ticino) on their smoking habits, perceived parents' and peers' approval and smoking. Multinomial logistic regression show that, as adolescents get older, more of the pro-smoking factors come from peers and parents, the higher the risk gets of being a "heavy smoker" has compared against having no experience with smoking. Living in a context with no factor of normative influence toward smoking play a protective role against smoking, and this effect becomes more important than more harmful the smoking behavior in question is. Furthermore, peers' descriptive norms are more influential for adolescents to become "light" and "heavy smokers", while smoking being approved by peers is important for adolescents to become accustomed to smoking. Findings support the different influence of parents' and peers' norms on adolescents' smoking, and highlight the importance of peers' model behavior as the most important factor influencing smoking during adolescence. Such results have implications for programs that aim to prevent or reduce smoking in early adolescence when friendship choice starts to become crucial.

To explore the behaviors related to infectious disease and family factors in primary and middle school students, and to provide evidence for improving behaviors related to infectious disease.
 A total of 8465 students were randomly surveyed by a standard questionnaire of behaviors related to infectious disease. Chi-square test was used to analyze the influential factors for behaviors related to infectious disease, and non conditional logistic regression analysis was used to analyze the multiple factors.
 The total formation rate of behaviors related to infectious disease was 66.4%. The rates for primary and middle school students were 69.4% and 62.8% respectively, with significant difference (P<0.05). There were significant differences in the following behaviors, such as washing hands before eating food, rarely buying snacks on outside stalls, informing teachers when showing infectious disease symptoms (all P<0.05), the degree for such behaviors in primary school students was higher than that in middle school students. There were also significant differences in the following behaviors, such as washing hands after using the toilet, blocking with a handkerchief, wiping while coughing and sneezing (all P<0.05), the degree for such behaviors in middle school students was higher than that in primary school students. Non conditional logistic regression analysis showed that the behaviors related to infectious disease in primary and middle school students were associated with parents' education degree, mother's occupation and living status with parents.
 Behaviors related to infectious disease in primary and middle school students need to be improved, and the formation of these behaviors may be related to many family factors.

Experiences and factors influencing a sample of teachers in New York state public elementary and middle schools to focus on environmental education in their teaching

NASA Astrophysics Data System (ADS)

Tooker, Gail Patricia

This study focuses on how fourteen elementary and middle level teachers in New York chose to teach environmental topics as part of their science curricula. Prior research suggested that factors influencing teachers to make curricular decisions are different from those that motivated them to become teachers in the first place (Espinet, et.al. 1992). This was supported by the results of this study, which found that most of these teachers made the decision to begin teaching environmental education (EE) well after deciding to become teachers and that the decision to teach EE was influenced by a variety of factors including participation in EE-oriented in-service programs, media coverage of environmental issues, encouragement from colleagues and school administrators to undertake EE, and personal experiences in childhood or early adulthood with the environment and/or with EE. Studies examining experiences that influence people to practice "environmentally responsible" behaviors (Chawla, 1995; McGarry, 1994; Tanner, 1994) suggested that positive childhood contacts with nature were important predictors for such behavior in adulthood. Findings of this study were largely consistent with these results, however, this sample of teachers viewed their childhood nature experiences as being mostly responsible for the development of their appreciation of the environment, while their actual decision to begin teaching EE was primarily influenced by other experiences, as discussed above. This study also examined how these teachers prepared themselves for teaching EE. The findings indicate that these teachers used a wide variety of preparation strategies. A minority reported becoming prepared for teaching EE through their pre-service teacher education programs. These results were in agreement with prior findings that most teacher education programs in this country do not include a focus on EE. Even where preparation for EE is included, it has been rated by the participants as

The purpose of this study was to examine the influence of Mayan education on the academic achievement of Indian and Ladino middle school students (N = 353) in Guatemala. This study also examined changes in ethnic identity achievement and the effects of changes in ethnic identity achievement on gains in self-esteem and other-group attitudes. Superior gains in academic skills for both Ladino and Indian students attending Mayan schools were found. The results also suggested that those students who increased their ethnic identity scores during their first year of middle school also increased their other-group attitudes. These results are discussed in terms of the benefits of Mayan education and ethnic identity achievement for both Indian and Ladino students. (c) 2006 APA, all rights reserved.

Despite investment in family planning programs and education, unmet need for family planning remains high among young women (aged 15-24) in low and middle-income countries, increasing the risk for unwanted pregnancies and adverse social and reproductive health outcomes. There is a dearth of cross-national research that identifies the differential impact of community level factors among youth in low and middle-income countries (LMICs), which is imperative for the design of structural level interventions aimed at increasing family planning use. Grounded in the socio-ecological framework, this paper utilizes Demographic and Health Survey (DHS) from 52 LMICs to examine the influence of community level reproductive, gender, fertility, literacy and economic indicators on modern contraceptive use among female youth. Analyses are conducted using multi-level logistic regressions with random community-level effects. Our findings highlight the positive influence of community level education attainment and negative influence of gender and fertility related norms on young women's contraceptive use. Additionally, increased exposure to mass media did not positively influence young women's uptake of modern contraceptive methods. Taken together, findings indicate that young women's contraceptive decision-making is greatly shaped by their social contexts. The commonalities and regional variations in community level influences provide support for both structural level interventions and tailored regional approaches to family planning interventions.

In recent years there has been a growth in the number of independent health policy analysis institutes in low- and middle-income countries which has occurred in response to the limitation of government analytical capacity and pressures associated with democratization. This study aimed to: (i) investigate the contribution made by health policy analysis institutes in low- and middle-income countries to health policy agenda setting, formulation, implementation and monitoring and evaluation; and (ii) assess which factors, including organizational form and structure, support the role of health policy analysis institutes in low- and middle-income countries in terms of positively contributing to health policy. Six case studies of health policy analysis institutes in Bangladesh, Ghana, India, South Africa, Uganda and Vietnam were conducted including two NGOs, two university and two government-owned policy analysis institutes. Case studies drew on document review, analysis of financial information, semi-structured interviews with staff and other stakeholders, and iterative feedback of draft findings. Some of the institutes had made major contributions to policy development in their respective countries. All of the institutes were actively engaged in providing policy advice and most undertook policy-relevant research. Relatively few were engaged in conducting policy dialogues, or systematic reviews, or commissioning research. Much of the work undertaken by institutes was driven by requests from government or donors, and the primary outputs for most institutes were research reports, frequently combined with verbal briefings. Several factors were critical in supporting effective policy engagement. These included a supportive policy environment, some degree of independence in governance and financing, and strong links to policy makers that facilitate trust and influence. While the formal relationship of the institute to government was not found to be critical, units within

1998-01-01

To assess the factors that influence medical students' borrowing and how these factors may affect access to the profession, specialty choice, and medical graduates' repayment behaviors. The borrowing patterns of the 3,495 indebted students enrolled at Jefferson Medical College of Thomas Jefferson University between 1989-90 and 1994-95 were analyzed. (Debt included both subsidized and unsubsidized debt.) These borrowing patterns were assessed in relation to changes in the cost of education, family (i.e., parents') income, availability of grant funding, legislative changes to loan-eligibility criteria (specifically, the Higher Education Amendments of 1992), and average interest rates on federal unsubsidized loans. The annual changes in average debt levels suggest that while cost of education, family resources, and availability of grant funding may be significant factors, changes in loan eligibility and prevailing interest rates on unsubsidized loan source also influence medical students' borrowing. A comparison of the borrowing patterns for three income groups (low, middle, high) further demonstrated that while overall fluctuations for low-income group mirrored changes in the cost and resource variables, annual borrowing fluctuations for the middle- and high-income groups were more reflective of the expansion of loan eligibility and reduced interest rates on unsubsidized loans. From 1989-90 to 1994-95 the average cost of education increased by $2,368. Average unsubsidized debt increased by $1,544 for the low-income group, $3,960 for the middle-income group, and $4,439 for the high-income group. The percentage of unsubsidized funding included in the borrowers' financing packages increased by just under 6% for the low-income group but almost 10% and 11% for the middle- and high-income groups, respectively. The results suggest that medical students borrow for a variety of reasons, ranging from financial need to personal financing or lifestyle choices. These reasons

The Temperament in Middle Childhood Questionnaire (TMCQ) is a widely used parent-report measure of temperament. However, neither its lower nor higher order structures has been tested via a bottom-up, empirically based approach. We conducted higher and lower order exploratory factor analyses (EFAs) of the TMCQ in a large ( N = 654) sample of 9-year-olds. Item-level EFAs identified 92 items as suitable (i.e., with loadings ≥.40) for constructing lower order factors, only half of which resembled a TMCQ scale posited by the measure's authors. Higher order EFAs of the lower order factors showed that a three-factor structure (Impulsivity/Negative Affectivity, Negative Affectivity, and Openness/Assertiveness) was the only admissible solution. Overall, many TMCQ items did not load well onto a lower order factor. In addition, only three factors, which did not show a clear resemblance to Rothbart's four-factor model of temperament in middle childhood, were needed to account for the higher order structure of the TMCQ.

Factors that may influence the experience of hot flushes by healthy middle-aged women.

Interest in menopausal symptoms in general and hot flushes (HFs) in particular has grown in recent years. This is mostly due to increased awareness and the vast impact these symptoms have on women's lives. Despite the high prevalence of women who experience HFs, a definitive etiology for HFs is yet to be found. Our objective was to review the current literature dealing with associated factors for experiencing HFs and to provide a synthesized overview on this common and often debilitating condition. We systematically searched the English-language literature in the PubMed database using relevant key words and included only those articles that contained information on associated factors for HFs in generally healthy midlife women. Both conflicting scientific results between studies documenting factors that influence HFs and the lack of validated measuring tools make it difficult to truly pinpoint associated factors for HFs. Nonetheless, we identified the following clusters of associated factors: the menopausal stages, sex steroid hormones, other endocrine agents, genetic polymorphisms, race/ethnicity, body mass index (BMI) and obesity, mood disorders, smoking, soy isoflavones and phytoestrogens, alcohol consumption, and physical activity. No single associated factor was consistently identified as having a major role in experiencing HFs. More resources should be directed to develop a unified study system along with multivariable analyses to get a better understanding of this condition, which often imposes a tremendous social and personal toll on the women who experience it.

Bicycle injuries are a leading cause of accidental death among children in the world, and bicycle-related injuries are also very common in China, thus to find out bicycle injury risk factors is imperative. This study aims to identify the cyclist-, bicycle- and road-related risk factors of bicycle injury, to develop health education programs as an intervention and to provide a scientific basis for establishing policies against bicycle injury. We selected two middle schools randomly among seven schools in Chaoshan rural areas,where the main means of transportation for students from home to school was bicycle. The subjects were middle school students from 7th to 9th grades from Gucuo Middle School and Hefeng Middle School. Cyclists were surveyed through questionnaires about bicycle injury in the past 12 months. Multivariable logistic analysis showed that compared with a combination-type road、 motor lane and a non-intact road were both risk factors of bicycle injuries. This was followed by riding with fatigue, non-motor lane and inattentive riding. Bicycle injuries are frequent in China. Three risk factors on bicycle traffic injury among middle school students in Chaoshan rural areas of China were identified. This study provides important data to develop intervention strategies for China and other developing countries.

The influence of mastery on mother's health in middle years: Moderating role of stressful life context.

2018-06-07

Using data from 416 middle-aged mothers gathered over the course of a decade, this study examined the influence of mastery trajectories (the initial level and change), on change in physical health. Mastery is defined as one's ability to control and influence his/her life and environment to reach a desired outcome or goal. Both the initial level and change in mastery from 1991 to 1994 were associated with decreased physical health problems over the middle years (1991-2001). Contextual moderation of this association by stressful life contexts including negative life events and work-family conflict was investigated. Moderation analysis showed that under conditions of low contextual life stressors, the level and increase in mastery significantly contributed to decreases in physical health problems in middle-aged mothers. Alternatively, conditions of high contextual life stressors inhibited the ability of mastery to influence physical health of mothers, suggesting that the positive health impact of mastery on physical health is mitigated by stressful life experiences. Implications for the need to maintain important personal resources, such as mastery, during times of stress are discussed. Copyright © 2018 John Wiley & Sons, Ltd.

In this paper, we aim to better understand the factors that contribute to the substantive performance of EIA systems in low and middle income countries. Substantive performance is defined as the extent to which the EIA process contributes to the EIA objectives for the long term, namely environmental protection or, even more ambitious, sustainable development. We have therefore developed a conceptual model in which we focus on the key actors in the EIA system, the proponent and the EIA authority and their level of ownership as a key capacity to measure their performance, and we distinguish procedural performance and somemore » contextual factors. This conceptual model is then verified and refined for the EIA phase and the EIA follow-up phase (permitting, monitoring and enforcement) by means of 12 case studies from Ghana (four cases) and Georgia (eight cases), both lower–middle income countries. We observe that in most cases the level of substantive performance increases during the EIA phase but drops during the EIA follow-up phase, and as a result only five out of 12 operational cases are in compliance with permit conditions or national environmental standards. We conclude, firstly that ownership of the proponent is the most important factor explaining the level of substantive performance; the higher the proponent's level of ownership the higher the level of substantive performance. The influence of the EIA authority on substantive performance is limited. Secondly, the influence of procedural performance on substantive performance seems less important than expected in the EIA phase but more important during the EIA follow-up phase. In order to improve substantive performance we learned two lessons. Firstly, increasing the proponent's level of ownership seems obvious, but direct change is probably difficult. However, where international finance institutes are involved they can increase ownership. Despite the limited influence of the EIA authority, a proactive

Toxoplasmosis is a zoonosis caused by Toxoplasma gondii. Risk factors include consumption of undercooked meat, raw vegetables, and unfiltered water. This study aims to determine the seroprevalence and spatial distribution of toxoplasmosis in Middle Java, Indonesia, using an EcoHealth approach, combined with geographic information system (GIS). A total of 630 participants were randomly selected from seven districts. Each participant completed a questionnaire and provided a blood sample. The seroprevalence of toxoplasmosis was 62.5%. Of those who were seropositive, 90.1% were IgG+, and 9.9% were IgG+ and IgM+. Several risk factors were identified, including living at elevations of ≤200 m, compared with >200 m (OR = 56.2; P < 0.001), daily contact with raw meat (OR = 1.8; P = 0.001), unfiltered water (OR = 1.7; P = 0.003), and density of cats (OR = 1.4; P = 0.045). Visualizing the spatial distribution of seropositive respondents highlighted clustering in lowland areas. This study highlighted that Middle Java has a high prevalence of toxoplasmosis and identified some important environmental, ecological, and demographic risk factors. When researching diseases, such as toxoplasmosis, where animal hosts, human lifestyle, and environmental factors are involved in transmission, an EcoHealth method is essential to ensure a fully collaborative approach to developing interventions to reduce the risk of transmission in high-risk populations.

This study examines the relationship of three sociocultural factors-media influence, peer teasing, and parent teasing/comments and three potential moderator variables-self-esteem, social comparison, and endorsement of male strength and athleticism-to drive for muscularity in middle school boys. There were 287 seventh and eighth grade boys who completed a questionnaire measuring these variables as well as body mass index (BMI) and pubertal status. Results indicated that media influence and male physical attributes endorsement were particularly important correlates of drive for muscularity. These findings have implications for programs designed to prevent body dissatisfaction among adolescent boys.

2006-06-01

The purposes of this study were 1) to identify gender-specific motivational factors associated with sports program participation and attrition in middle school students and 2) to examine the relationships among sports program participation, physical activity, and sedentary behavior in this age group. Seventh and eighth grade students (N = 1692) completed a questionnaire to measure sports program participation and factors that may motivate continued participation in or attrition from sports. The psychometric properties of the participation and attrition scales were tested using gender-separate exploratory factor analysis. Analysis of variance (participation status*gender) was used to identify differences in motivational factor scores and physical activity variables. Eighty percent of the students were recent participants (within the past year), 10% were former participants, and 10% had never participated. For boys, the participation factors were labeled (in order) competition, social benefits, and fitness. For girls, factor structures were slightly different than the boys, which loaded as; social + skill benefits, competition, and fitness. For both genders, lack of interest, coaching problems, and time barriers were identified as attrition factors. Recent sport participants reported more time in vigorous (p < .01), stretching (p = .03), and strengthening activities (p < .01) and less time watching television (p < .01). Gender-specific motivational factors exist for middle school youth; boys are more attracted to the competitive aspects of sports whereas girls are more motivated by the social opportunities that sports provide. Boys and girls who participate in sports are more physically active, so it is important to develop programs that children want to participate in and maximize retention.

Farrell, Albert D; Mehari, Krista R; Kramer-Kuhn, Alison M; Mays, Sally A; Sullivan, Terri N

2015-06-01

This study examined factors that influenced the use of skills taught in a school-based universal violence prevention program. Interviews were conducted with 91 students from two urban schools (83% were African American and 12% multiracial) and 50 students from a nearby county school (52% were White, 32% African American, and 12% multiracial). About half the sample (54%) was male. All had been in sixth grade classrooms where the Second Step (Committee for Children, 1997b) violence prevention curriculum had been implemented earlier in the school year or in the preceding school year. Qualitative analysis of interview transcripts suggested that participants' use of intervention skills was influenced by their beliefs and values, perceived relevance and effectiveness of the skill, issues related to enacting the behavior, and contextual factors. These findings highlight the need for a more intensive and comprehensive effort to address barriers and supports that influence the relevance and impact of school-based violence prevention programs.

2017-11-27

In the present research, the influence of racial diversity among classmates and friends on changes in racial self-identification among multiracial youth was examined (n = 5,209; M age  = 10.56 years at the beginning of sixth grade). A novel individual-level measure of diversity among classmates based on participants' course schedules was utilized. The findings revealed that although there was some fluidity in multiracial identification at the beginning of middle school, changes in multiracial identification were more evident later in middle school. In addition, although diversity among classmates and friends both increased the likelihood of multiracial identification in the beginning of middle school, only diversity among friends mattered later in middle school, when fluidity in multiracial identification was at its peak. © 2017 The Authors.

Jurkowski, Marek K; Bobek-Billewicz, Barbara

2007-01-01

Sleep is a universal phenomenon of human and animal lives, although the importance of sleep for homeo-stasis is still unknown. Sleep disturbances influence many behavioral and physiologic processes, leading to health complications including death. On the other hand, sleep improvement can beneficially influence the course of healing of many disorders and can be a prognostic of health recovery. The factors influencing sleep have different biological and chemical origins. They are classical hormones, hypothalamic releasing and inhibitory hormones, neuropeptides, peptides and others as cytokines, prostaglandins, oleamid, adenosine, nitric oxide. These factors regulate most physiologic processes and are likely elements integrating sleep with physiology and physiology with sleep in health and disorders.

The impact of middle manager affective commitment on perceived improvement program implementation success.

PubMed

Fryer, Ashley-Kay; Tucker, Anita L; Singer, Sara J

Recent literature suggests that middle manager affective commitment (emotional attachment, identification, and involvement) to an improvement program may influence implementation success. However, less is known about the interplay between middle manager affective commitment and frontline worker commitment, another important driver of implementation success. We contribute to this research by surveying middle managers who directly manage frontline workers on nursing units. We assess how middle manager affective commitment is related to their perceptions of implementation success and whether their perceptions of frontline worker support mediate this relationship. We also test whether a set of organizational support factors foster middle manager affective commitment. We adapt survey measures of manager affective commitment to our research context of hospitals. We surveyed 67 nurse managers from 19 U.S. hospitals. We use hierarchical linear regression to assess relationships among middle manager affective commitment to their units' falls reduction program and their perceptions of three constructs related to the program: frontline worker support, organizational support, and implementation success. Middle manager affective commitment to their unit's falls reduction program is positively associated with their perception of implementation success. This relationship is mediated by their perception of frontline worker support for the falls program. Moreover, middle managers' affective commitment to their unit's falls program mediates the relationship between perceived organizational support for the program and perceived implementation success. We, through this research, offer an important contribution by providing empirical support of factors that may influence successful implementation of an improvement program: middle manager affective commitment, frontline worker support, and organizational support for an improvement program.

2017-01-01

Objectives This study aimed to determine the prevalence of suicidal ideation among young and middle-aged adults, and explore the risk factors that affect suicidal ideation. Methods A descriptive study design was used for secondary data analysis. A total sample of 5,214 was drawn from two waves (2012–2013) of the 7th Korea Health Panel (KHP) survey. The KHP data were collected by a well-trained interviewer using the face-to-face method during home visits as well as self-report method. Descriptive statistics of frequency, percentage, chi-square test, and logistic regression analysis were performed using SPSS 22.0. Results The prevalence of suicidal ideation in young and middle-aged adults was 4.4% and 5.6%, respectively. For young adults, suicidal ideation risk was higher among those with low income or heavy drinking habits. In middle-aged adults, low income, poor perceived health status, negative perception of peer-compared health status, and negative social perspective were the major risk factors. Conclusion There is considerable risk of suicidal ideation in adulthood. Opportunities for increased income, avoidance of heavy drinking, and the construction of positive subjective health status and social perspective should be considered in suicide prevention interventions for Korean young and middle-aged adults.

The present study aimed to investigate the status of physical activity and the differences in psychological factors associated with physical activity from the perspective of transtheoretical model stages between prime- and middle-aged Japanese. The study involved 375 prime-aged volunteers (175 men, 200 women) and 557 middle-aged volunteers (247 men, 310 women) living in Kuse, a town in Okayama Prefecture, Japan. We found that the prime-aged men at the preparation stage had significantly higher self-efficacy scores than at the contemplation stage (p<0.01). Middle-aged men had significantly higher self-efficacy scores at the contemplation stage than at the precontemplation stage (p<0.001). Middle-aged women, meanwhile, had significantly higher self-efficacy scores at the maintenance stage than at the action stage (p<0.01), and at the contemplation stage than at the precontemplation stage (p<0.001). The present findings provide valuable information about the differences in psychological factors affecting physical activity between prime-aged and middle-aged community-dwelling Japanese. This information may be useful to health professionals as they develop effective community-based intervention programs for target populations.

2001-01-01

The development of gender role qualities (attitudes, personality, leisure activities) from middle childhood to early adolescence was studied to determine whether siblings' gender role qualities predicted those of their sisters and brothers. Participants were 198 firstborn and second-born siblings (Ms = 10 years 9 months and 8 years 3 months, respectively, in Year 1) and their parents. Families were interviewed annually for 3 years. Firstborn siblings' qualities in Year 1 predicted second-born children's qualities in Year 3 when both parent and child qualities in Year 1 were controlled, a pattern consistent with a social learning model of sibling influence. Parental influence was more evident and sibling influence less evident in predicting firstborns' qualities; for firstborns, sibling influences suggested a de-identification process.

It is estimated that the percentage of students using illicit substances by sixth grade has tripled over the last decade not only in developed countries but in developing countries as well probably due to the transition to a more Western society. Although much has been done to understand the mechanisms underlying substance abuse, few studies have been conducted with minority ethnic and religious groups such as Middle Eastern Youth. The primary goal of this study was to determine whether there are differences in factors contributing to substance abuse in adolescents from Lebanon versus the U.S.A. and to decipher the role of spirituality, religion, and culture among other factors that may influence substance abuse. A correlational cross-sectional design was used with adolescents living in two different countries: Los Angeles, California and Beirut, Lebanon. Muslim adolescents had significantly less rates of alcohol and substance use than Christians in both Lebanon and Los Angeles. More years lived in the U.S.A. increases the likelihood of abuse for both Muslims and Christians. Attachment to God and family was negatively associated with substance abuse. These results among others facilitate a better understanding of the influence of culture, religion, family and personal factors on substance abuse. Culturally sensitive interventions could benefit from the findings of this pilot study.

Contrast sensitivity is strongly associated with daily functioning among older adults, but the genetic and environmental contributions to this ability are unknown. Using the classical twin method, we addressed this issue by examining contrast sensitivity at five spatial frequencies (1.5–18 cycles per degree) in 718 middle-aged male twins from the Vietnam Era Twin Study of Aging (VETSA). Heritability estimates were modest (14%–38%), whereas individual-specific environmental influences accounted for 62%–86% of the variance. Identifying the types of individual-specific events that impact contrast sensitivity may suggest interventions to modulate this ability and thereby improve overall quality of life as adults age.

Middle managers have received little attention in extant health services research, yet they may have a key role in healthcare innovation implementation. The gap between evidence of effective care and practice may be attributed in part to poor healthcare innovation implementation. Investigating middle managers' role in healthcare innovation implementation may reveal an opportunity for improvement. In this paper, we present a theory of middle managers' role in healthcare innovation implementation to fill the gap in the literature and to stimulate research that empirically examines middle managers' influence on innovation implementation in healthcare organizations. Extant healthcare innovation implementation research has primarily focused on the roles of physicians and top managers. Largely overlooked is the role of middle managers. We suggest that middle managers influence healthcare innovation implementation by diffusing information, synthesizing information, mediating between strategy and day-to-day activities, and selling innovation implementation. Teamwork designs have become popular in healthcare organizations. Because middle managers oversee these team initiatives, their potential to influence innovation implementation has grown. Future research should investigate middle managers' role in healthcare innovation implementation. Findings may aid top managers in leveraging middle managers' influence to improve the effectiveness of healthcare innovation implementation.

To evaluate the quality of life (QOL) of overweight and obese middle or high school students and identify relevant factors influencing their QOL scores. 716 students were recruited from 6 middle or high schools in Hangzhou, China. The Chinese version of the Youth Quality of Life Instrument-Weight Module (YQOL-W) was self administered. The YQOL-W scores were compared among different BMI groups, gender, educational status, annual household income, parental education and recruitment community using t test or one-way analysis of variance. The independent association of these variables with QOL among overweight and obese students was examined using multivariable linear regression modeling. Overweight and obese students reported lower total scores, self, social and environment scores than their normal weight peers (all P<0.001). The QOL of overweight and obese middle and high school students was associated with BMI value, gender, educational status, parental education, and recruitment community. Girls had lower total scores, self, social and environment domain scores than boys (all P<0.001); high school students had lower total and three domain scores than middle school students (all P<0.05). Students whose fathers had higher education reported higher total scores, self and social scores than students with less educated fathers (all P<0.05). Students whose mothers had higher education reported higher environment scores than students with less educated mothers (P = 0.01). Students from migrant communities reported significantly lower total scores, self and social scores than those from rural communities (all P<0.05), but comparable scores with those from urban communities (P>0.05). Students from migrant communities reported comparable environment scores with those from rural and urban communities (P>0.05). Overweight and obesity have negative effects on students' quality of life. Therefore weight specific QOL could be included in weight reduction interventions as a

Lexical influences on competing speech perception in younger, middle-aged, and older adults

PubMed Central

Helfer, Karen S.; Jesse, Alexandra

2015-01-01

The influence of lexical characteristics of words in to-be-attended and to-be-ignored speech streams was examined in a competing speech task. Older, middle-aged, and younger adults heard pairs of low-cloze probability sentences in which the frequency or neighborhood density of words was manipulated in either the target speech stream or the masking speech stream. All participants also completed a battery of cognitive measures. As expected, for all groups, target words that occur frequently or that are from sparse lexical neighborhoods were easier to recognize than words that are infrequent or from dense neighborhoods. Compared to other groups, these neighborhood density effects were largest for older adults; the frequency effect was largest for middle-aged adults. Lexical characteristics of words in the to-be-ignored speech stream also affected recognition of to-be-attended words, but only when overall performance was relatively good (that is, when younger participants listened to the speech streams at a more advantageous signal-to-noise ratio). For these listeners, to-be-ignored masker words from sparse neighborhoods interfered with recognition of target speech more than masker words from dense neighborhoods. Amount of hearing loss and cognitive abilities relating to attentional control modulated overall performance as well as the strength of lexical influences. PMID:26233036

Regular physical activity is important for midlife women. Models and theories help better understanding this behavior among middle-aged women and better planning for change behavior in target group. This study aimed to investigate predictive factors of regular physical activity among middle-aged women based on PRECEDE model as a theoretical framework. This descriptive-analytical study was performed on 866 middle-aged women of Hamadan City western Iran, recruited with a proportional stratified sampling method in 2015. The participants completed a self-administered questionnaire including questions on demographic characteristics and PRECEDE model constructs and IPAQ questionnaire. Data were then analyzed by SPSS-16 and AMOS-16 using the Pearson correlation test and the pathway analysis method. Overall, 57% of middle-aged women were inactive (light level) or not sufficiently active. With SEM (Structural Equation Modeling) analysis, knowledge b=0.84, P<0.001, attitude b=0.799, P<0.001, self-efficacy b=0.633, P<0.001 as predisposing factor and social support as reinforcing factor b=0.2, P<0.001 were the most important predictors for physical activity among middle-aged women in Hamadan. The framework of the PRECEDE model is useful in understanding regular physical activity among middle-aged women. Furthermore, results showed the importance of predisposing and reinforcing factors when planning educational interventions.

Relative importance of demographic, socioeconomic and health factors on life expectancy in low- and lower-middle-income countries.

We attempted to identify the pathways by which demographic changes, socioeconomic inequalities, and availability of health factors influence life expectancy in low- and lower-middle-income countries. Data for 91 countries were obtained from United Nations agencies. The response variable was life expectancy, and the determinant factors were demographic events (total fertility rate and adolescent fertility rate), socioeconomic status (mean years of schooling and gross national income per capita), and health factors (physician density and human immunodeficiency virus [HIV] prevalence rate). Path analysis was used to determine the direct, indirect, and total effects of these factors on life expectancy. All determinant factors were significantly correlated with life expectancy. Mean years of schooling, total fertility rate, and HIV prevalence rate had significant direct and indirect effects on life expectancy. The total effect of higher physician density was to increase life expectancy. We identified several direct and indirect pathways that predict life expectancy. The findings suggest that policies should concentrate on improving reproductive decisions, increasing education, and reducing HIV transmission. In addition, special attention should be paid to the emerging need to increase life expectancy by increasing physician density.

Zygosity is influenced by many factors. Monozygotic twins occur spontaneously in approximately 1 in 250 births and are felt to increase twofold with ovulation induction techniques. Monozygotic twinning also increases in proportion to the number of blastocysts transferred during in vitro fertilisation. In contrast, dizygotic twinning appears to be influenced by race, genetic factors, maternal age, fertility enhancing drugs, folic acid supplementation, and maternal nutritional status.

Population-based cross-sectional studies in rural, urban-poor, and urban-middle class women (35-70 y) were performed at multiple sites. We evaluated 6853 women (rural 2616, 5 sites; urban-poor 2008, 4 sites; urban middle-class 2229, 11 sites) for socioeconomic, lifestyle, anthropometric and biochemical risk factors. Descriptive statistics are reported. Mean levels of body mass index (BMI), waist circumference, waist-hip ratio (WHR), systolic BP, fasting glucose and cholesterol in rural, urban-poor and urban-middle class women showed significantly increasing trends (ANOVAtrend, p <0.001). Age-adjusted prevalence of diabetes and risk factors among rural, urban-poor and urban-middle class women, respectively was, diabetes (2.2, 9.3, 17.7%), overweight BMI ≥25 kg/m2 (22.5, 45.6, 57.4%), waist >80 cm (28.3, 63.4, 61.9%), waist >90 cm (8.4, 31.4, 38.2%), waist hip ratio (WHR) >0.8 (60.4, 90.7, 88.5), WHR>0.9 (13.0, 44.3, 56.1%), hypertension (31.6, 48.2, 59.0%) and hypercholesterolemia (13.5, 27.7, 37.4%) (Mantel Haenszel X2 ptrend <0.01). Inverse trend was observed for tobacco use (41.6, 19.6, 9.4%). There was significant association of hypertension, hypercholesterolemia and diabetes with overweight and obesity (adjusted R2 0.89-0.99). There are significant location based differences in cardiometabolic risk factors in India. The urban-middle class women have the highest risk compared to urban-poor and rural.

Reciprocal Influences of Personality and Job Characteristics Across Middle Adulthood

PubMed Central

Sutin, Angelina R.; Costa, Paul T.

2010-01-01

The present research uses an economically diverse, middle-aged sample to examine the concurrent and longitudinal interplay between personality and occupational experiences. Using the Five-Factor Model of personality and the Demand-Control Model of the occupational environment as guiding frameworks, participants (N = 722) reported on their personality, job characteristics, and occupational history; a subset (n = 297) made the same ratings approximately 10 years later. Measured concurrently, emotionally stable, extraverted, open, and conscientious participants reported jobs with greater decision-making latitude, whereas disagreeable participants had more physically demanding and dangerous jobs. Longitudinal cross-lagged analyses revealed that personality was associated with changes in decision latitude, hazardous working conditions, and physical demands. None of the job characteristics predicted change in personality at the factor level. Thus, personality shaped occupational experiences, but occupational experiences had minimal impact on personality. Support for the Five-Factor Theory perspective and implications for environmental approaches to personality development are discussed. PMID:20433619

The objective of this study was to examine the effects of an integrated, multi-component, school-based intervention programme on cardiovascular disease (CVD) risk factors among a multi-ethnic cohort of middle school students. HEALTHY was a cluster randomized, controlled, primary prevention trial. Middle school was the unit of randomization and intervention. Half of the schools were assigned to an intervention programme consisting of changes in the total school food environment and physical education classes, enhanced by educational outreach and behaviour change activities and promoted by a social marketing campaign consisting of reinforcing messages and images. Outcome data reported (anthropometrics, blood pressure and fasting lipid levels) were collected on a cohort of students enrolled at the start of 6th grade (∼11-12 years old) and followed to end of 8th grade (∼13-14 years old). Forty-two middle schools were enrolled at seven field centres; 4363 students provided both informed consent and CVD data at baseline and end of study. The sample was 52.7% female, 54.5% Hispanic, 17.6% non-Hispanic Black, 19.4% non-Hispanic White and 8.5% other racial/ethnic combinations, and 49.6% were categorized as overweight or obese (body mass index ≥ 85th percentile) at baseline. A significant intervention effect was detected in the prevalence of hypertension in non-Hispanic Black and White males. The intervention produced no significant changes in lipid levels. The prevalence of some CVD risk factors is high in minority middle school youth, particularly males. A multi-component, school-based programme achieved only modest reductions in these risk factors; however, promising findings occurred in non-Hispanic Black and White males with hypertension. © 2012 The Authors.

McWaters, Kathy Jean

2001-07-01

Classroom assessment practices of middle school science teachers were identified and the influence of national and state science standards on these practices was examined. In Phase I of this study a mail questionnaire was sent to 450 middle school (grades 5,6,7 and 8) science teachers in 17 parishes in Louisiana to obtain information about their classroom assessment practices. In Phase II, nine middle school teachers in eight departmentalized classrooms, two classes at each grade, participated in a qualitative study. Data were collected through questionnaires, classroom observations, interviews and document analysis. Data analysis revealed three major categories of classroom assessment targets: (a) student achievement, (b) student attitudes and, (c) student products. Results indicated that most teachers are using different assessment methods when assessing different achievement targets, as recommended by science reform documents. It was also determined that many teachers are using appropriate methods to assess student learning. While teachers reported that students spend an inordinate amount of time engaged in assessment activities, classroom observations suggested that the activities were not always written tests or graded activities. Another key finding is that there is a disconnect between the quality of teaching and the quality of assessment. Teachers who teach the material recommended by science reform documents and use recommended instructional strategies were observed to stop teaching and engage students in a "test rehearsal" geared towards rote memorization of factual information. Data suggest that the national and state science content standards are influencing the content and the format of teacher-made tests. Teachers' reported using the standards during assessment construction or selection in a wide variety of ways. The most direct use of the standards reported was to select content, format and cognitive level for test items. A more circumspect approach

Aerosol influence on energy balance of the middle atmosphere of Jupiter

Aerosols are ubiquitous in planetary atmospheres in the Solar System. However, radiative forcing on Jupiter has traditionally been attributed to solar heating and infrared cooling of gaseous constituents only, while the significance of aerosol radiative effects has been a long-standing controversy. Here we show, based on observations from the NASA spacecraft Voyager and Cassini, that gases alone cannot maintain the global energy balance in the middle atmosphere of Jupiter. Instead, a thick aerosol layer consisting of fluffy, fractal aggregate particles produced by photochemistry and auroral chemistry dominates the stratospheric radiative heating at middle and high latitudes, exceeding the local gas heating rate by a factor of 5–10. On a global average, aerosol heating is comparable to the gas contribution and aerosol cooling is more important than previously thought. We argue that fractal aggregate particles may also have a significant role in controlling the atmospheric radiative energy balance on other planets, as on Jupiter. PMID:26694318

The increased prevalence of diabetes in Middle Eastern countries is a health policy priority. Important risk factors for diabetes have been identified. Lifestyle interventions and adherence to medications are central to disease prevention and management. This review focuses on the management of type 2 diabetes mellitus in Middle Eastern countries. The aim is to identify the ways in which knowledge, health beliefs, and social and cultural factors influence adherence to medication and lifestyle measures. Thirty-four studies were identified following a systematic search of the literature. The studies describe the influence of knowledge, health beliefs, culture, and lifestyle on the management of type 2 diabetes mellitus in the Middle East. Findings indicate a lack of health knowledge about diabetes among populations, which has implications for health behaviors, medication adherence, and treatment outcomes. Many identified health beliefs and cultural lifestyle factors, such as religious beliefs, beliefs about fasting during Ramadan, and sedentary lifestyles played a role in patients’ decisions. For better management of this disease, a collaborative approach between patients, their families, health care professionals, and governments should be adopted. Implementing behavioral strategies and psychological interventions that incorporate all health care professionals in the management process have been shown to be effective methods. Such services help patients change their behavior. However, the utilization of such services and interventions is still limited in Arabian countries. Physicians in the Middle East are the health care professionals most involved in the care process. PMID:27354775

Yantai is a developed medium-sized coastal city in Eastern China, having a population of 1.6845 million. With the development of economy, some middle-aged and adolescent people (< 45 years) devote themselves to work and suffer from greater stress, which makes them ignore their own health. Moreover, they have unhealthy lifestyles and lack the knowledge of cardiovascular risk factors. To identify the risk factors for first acute myocardial infarction in middle-aged and adolescent people in Yantai, a developed medium-sized coastal city in Eastern China. A total of 154 consecutive patients with first acute myocardial infarction (< 45 years), were enrolled in case group, and 462 patients without myocardial infarction were enrolled in control group. Three controls with the same sex and age were matched to each case. The risk factors were identified with univariate and multivariate analysis. Unhealthy food habit (eating seafood and meanwhile drinking beer), hypertension, current smokers, self-perceived stress, diabetes mellitus, obesity, sleep insufficience, hypercholesterolaemia and fatigue were independent risk factors for first acute myocardial infarction (P < 0.05). Besides those recognized risk factors for cardiovascular disease (hypertension, hypercholesterolemia, diabetes mellitus and smoking), eating seafood and meanwhile drinking beer, self-perceived stress, sleep insufficience, obesity and fatigue were also the risk factors for first acute myocardial infarction in middle-aged and adolescent people in Yantai.

Factors influencing habitat selection by arboreal pit vipers.

We studied factors influencing habitat selection by two arboreal species of pit viper, namely Trimeresurus malabaricus (Malabar pit viper) and T. gramineus (Bamboo pit viper). The macrohabitat of these species was classified as forest, forest edge, or open habitat. To determine microhabitat selection, a variety of features at every other snake location were measured. Whether or not the animal was found in a tree, the tree species, its height of perch, position on the branch (distal/ apical/middle), diameter of the branch, the tree canopy (thick/sparse) and vegetation of the area (thick/sparse) were recorded. Assessment of habitat was done to determine how patterns of habitat use vary seasonally. Shaded ambient (air) temperatures and humidity were recorded. Data pertaining to 90 individuals of T. malabaricus and 100 individuals of T. gramineus were recorded. Trimeresurus malabaricus selected home ranges that included areas with thick vegetation and were encountered at regions of higher altitude. Neither of the species was found in open habitats. Both of the species preferred diverse habitats and were spread over the entire available space during the monsoon; they did not show any preference for the perch height during different seasons. Males had a positive correlation between body mass and preferred perch diameter. The present study suggests that several factors play an important role in habitat selection by these arboreal pit vipers, thus making them highly habitat-specific.

To explore the status and influencing factors on anxiety sensitivity among middle school students in Chongqing. 58 classes from 12 schools were randomly selected in four administrative districts of Chongqing city. A total number of 2700 students was included for final analysis including 48.5% from junior high school and 51.5% from senior high school students with 49.2% boys and 50.8% girls. The Chinese version of the Anxiety Sensitivity Index-Revision, Adolescent Self-Rating Life Events Check List (ASLEC) and State-Trait Anxiety Inventory (STAI) were used. (1) There was no significant difference between grade groups (P = 0.49). (2) The level of girl's anxiety sensitivity was always higher than boy's (P < 0.001). (3) Data from multiple linear regression showed that the influential factors to the degree of anxiety sensitivity were: state of anxiety, trait anxiety, life events, sex, stress from learning, etc (standard coefficients of regression were 0.258, 0.163, 0.112, 0.093, 0.124, -0.096, 0.096). The major influential factors of anxiety sensitivity would include: sex, stress from learning, life events, interpersonal relationship, state of anxiety and trait anxiety.

We aimed to investigate the overall prevalence and possible factors influencing the occurrence of crossed cerebellar diaschisis after acute middle cerebral artery infarction using whole-brain CT perfusion. A total of 156 patients with unilateral hypoperfusion of the middle cerebral artery territory formed the study cohort; 352 patients without hypoperfusion served as controls. We performed blinded reading of different perfusion maps for the presence of crossed cerebellar diaschisis and determined the relative supratentorial and cerebellar perfusion reduction. Moreover, imaging patterns (location and volume of hypoperfusion) and clinical factors (age, sex, time from symptom onset) resulting in crossed cerebellar diaschisis were analysed. Crossed cerebellar diaschisis was detected in 35.3% of the patients with middle cerebral artery infarction. Crossed cerebellar diaschisis was significantly associated with hypoperfusion involving the left hemisphere, the frontal lobe and the thalamus. The degree of the relative supratentorial perfusion reduction was significantly more pronounced in crossed cerebellar diaschisis-positive patients but did not correlate with the relative cerebellar perfusion reduction. Our data suggest that (i) crossed cerebellar diaschisis is a common feature after middle cerebral artery infarction which can robustly be detected using whole-brain CT perfusion, (ii) its occurrence is influenced by location and degree of the supratentorial perfusion reduction rather than infarct volume (iii) other clinical factors (age, sex and time from symptom onset) did not affect the occurrence of crossed cerebellar diaschisis.

The distribution characteristics of carbon density under aerially seeded Pinus massoniana plantations in Ganzhou City of Jiangxi Province were studied. Total 15 factors, including site, stand, understory vegetation, litter and so on were selected to establish a relationship model between stand carbon density and influencing factors, and the main influencing factors were also screened. The results showed that the average carbon density was 98.29 t·hm -2 at stand level with soil layer (49.58 t·hm -2 ) > tree layer (45.25 t·hm -2 ) > understory vegetation layer (2.23 t·hm -2 ) > litter layer (1.23 t·hm -2 ). Significantly positive correlations were found among the tree, litter and soil layers, but not among the other layers. The main factors were tree density, avera-ge diameter at breast height (DBH), soil thickness, slope position, stand age and canopy density to affect carbon density in aerially seeded P. massoniana plantations. The partial correlation coefficients of the six main factors ranged from 0.331 to 0.434 with significance by t test. The multiple correlation coefficient of quantitative model I reached 0.796 with significance by F test (F=9.28). For stand density, the best tree density and canopy density were 1500-2100 plants·hm -2 and 0.4-0.7, respectively. The moderate density was helpful to improve ecosystem carbon sequestration. The carbon density increased with increasing stand age, DBH and soil thickness, and was higher in lower than middle and upper slope positions.

Toward a Middle-Range Theory of Weight Management.

PubMed

Pickett, Stephanie; Peters, Rosalind M; Jarosz, Patricia A

2014-07-01

The authors of this paper present the middle-range theory of weight management that focuses on cultural, environmental, and psychosocial factors that influence behaviors needed for weight control. The theory of weight management was developed deductively from Orem's theory of self-care, a constituent theory within the broader self-care deficit nursing theory and from research literature. Linkages between the conceptual and middle-range theory concepts are illustrated using a substruction model. The development of the theory of weight management serves to build nursing science by integrating extant nursing theory and empirical knowledge. This theory may help predict weight management in populations at risk for obesity-related disorders. © The Author(s) 2014.

2017-01-01

The present study sought to examine self-control, parental support, and peer support as internal and external protective factors that buffer the influence of adolescent stress on delinquency among Korean adolescents. To this end, the paper utilized the 1st-year data from the Korea Youth Panel Study (KYPS) conducted by the National Youth Policy Institute; the study surveyed a total of 3,449 2nd-year middle school students. The results of the hierarchical regression analysis indicated that despite high levels of stress, high self-control mitigated the negative influence of stress on delinquency in adolescents. In contrast, parental and peer support were only found to be directly influential on juvenile delinquency. Parental support had only negative influences on status delinquency, and peer support had positive influences on both status and serious delinquency. Based on these results, we propose implications for preventing and intervening with juvenile delinquency.

Although several eating disorder prevention programs reduce eating disorder risk factors and symptoms for female high school and college students, few efficacious prevention programs exist for female middle school students, despite the fact that body image and eating disturbances often emerge then. Two pilot trials evaluated a new dissonance-based eating disorder prevention program for middle school girls with body image concerns. Female middle school students with body dissatisfaction from two sites [Study 1: N = 81, M age = 12.1, standard deviation (SD) = 0.9; Study 2: N = 52, M age = 12.5, SD = 0.8] were randomized to a dissonance intervention (MS Body Project) or educational brochure control; Study 2 included a 3-month follow-up. Intervention participants showed significant post-test reductions in only one of the six variables with both Studies 1 and 2 (i.e., pressure to be thin and negative affect, respectively), though post-test effect sizes suggested medium reductions in eating disorder risk factors and symptoms (Study 1: M d = .40; Study 2: M d = .65); reductions at 3-month follow-up in Study 2 were not evident (M d = .19). Results suggest that this new middle school version of the Body Project is producing medium magnitude reductions in eating disorder risk factors at post-test but that effects are showing limited persistence. Continued refinement and evaluation of this intervention appears warranted to develop more effective prevention programs for this age group. © 2014 Wiley Periodicals, Inc.

School as a risk factor for psychoactive substance use by middle school students

For the majority of Polish students school is a source of negative experiences and therefore may increase the risk of adolescent problem behaviors. The results of the study conducted in Warsaw middle schools (N=2244, 54% girls) indicated that changes for worse (between 7 and 8 grade) in students' behavior increase the risk of drug use. However, changes for better in students' perception of school value and school achievements are risk factors, too (even when family and peer risk factors are controlled). PMID:21152104

Predictors of scientific understanding of middle school students

NASA Astrophysics Data System (ADS)

Strate, Joshua Matthew

The purpose of this study was to determine if middle school student scientific understanding could be predicted by the variables: standardized 5th grade score in science, standardized 5th grade score in mathematics, standardized 5th grade score in reading, student attitude towards science, socioeconomic status, gender, and ethnicity. The areas of the comprehensive literature review were trends in science learning and teaching, research in the K-12 science education arena, what factors have influenced K-12 science education, scientific understanding, what research has been done on K-12 scientific understanding, and what factors have influenced science understanding in the K-12 arenas. Based on the results of the literature review, the researcher of this study examined a sample of middle school 8th grade students. An Attitude Towards Science Survey (SATS) Simpson & Oliver (1990) and a Survey of Scientific Understandings (Klapper, DeLucia, & Trent, 1993) were administered to these 116 middle school 8th grade students drawn from a total population of 1109 who attend this middle school in a typical county in Florida during the 2010- 2011 school year. Multiple linear regression analysis was used to test each sub-hypothesis and to provide a model that attempted to predict student scientific understanding. Seven null sub-hypotheses were formed to determine if there were significant relationships between student scientific understanding and the abovementioned variables. The results of the tests of the seven null sub-hypotheses showed that the sub-hypothesis that involved socioeconomic status was rejected, which indicated that the socioeconomic status of a family does influence the level of scientific understanding of a student. Low SES students performed lower on the scientific understanding survey, on average, than high SES students. This study can be a source of information for teachers in low-income schools by recognizing potential areas of concern for low

Crossed cerebellar diaschisis was significantly associated with hypoperfusion involving the left hemisphere, the frontal lobe and the thalamus. The degree of the relative supratentorial perfusion reduction was significantly more pronounced in crossed cerebellar diaschisis-positive patients but did not correlate with the relative cerebellar perfusion reduction. Our data suggest that (i) crossed cerebellar diaschisis is a common feature after middle cerebral artery infarction which can robustly be detected using whole-brain CT perfusion, (ii) its occurrence is influenced by location and degree of the supratentorial perfusion reduction rather than infarct volume (iii) other clinical factors (age, sex and time from symptom onset) did not affect the occurrence of crossed cerebellar diaschisis. © The Author(s) 2015.

The aim of this communication is to describe the cardiovascular risk factors affecting a Mexican urban middle-class population. A convenience sample of 2602 middle class urban subjects composed the cohort of the Lindavista Study, a prospective study aimed to determine if conventional cardiovascular risks factors have the same prognosis impact as in other populations. For the baseline data, several measurements were done: obesity indexes, smoking, blood pressure, fasting serum glucose, total cholesterol, HDL-c, LDL-c and triglycerides. This paper presents the basal values of this population, which represents a sample of the Mexican growing urban middle-class. The mean age in the sample was 50 years; 59% were females. Around 50% of the entire group were overweighed, while around 24% were obese. 32% smoked; 32% were hypertensive with a 20% rate of controlled pressure. 6% had diabetes, and 14% had impaired fasting glucose; 66% had total cholesterol ≥ 200 mg/dL; 62% showed HDL-c levels<40 mg/dL; 52% triglycerides>150 mg/dL, and 34% levels of LDL-c ≥ 160 mg/dL. Half of the population studied had the metabolic syndrome. These data show a population with a high-risk profile, secondary to the agglomeration of several cardiovascular risk factors.

Gender and Middle School Science: An Examination of Intrinsic and Extrinsic Factors Affecting Achievement

NASA Astrophysics Data System (ADS)

Austin, Jennifer

Gender differences in middle school science were examined utilizing a mixed-methods approach. The intrinsic and extrinsic experiences of male and female non-gifted high-achieving students were investigated through the administration of the CAIMI, student interviews, teacher questionnaires, observations, and document examination. Male and female students were selected from a rural Northeast Georgia school district based on their high performance and high growth during middle school science. Eighty-three percent of the student participants were white and 17% were Hispanic. Half of the male participants and one third of the female participants were eligible for free and reduced meals. Findings revealed that male participants were highly motivated, whereas female participants exhibited varying levels of motivation in science. Both male and female students identified similar instructional strategies as external factors that were beneficial to their success. Due to their selection by both genders, these instructional strategies were considered to be gender-neutral and thereby useful for inclusion within coeducational middle school science classrooms.

To understand the prevalence and risk factors of non-suicidal self-injury in middle school students. 1312 middle school students of Pengzhou and Santai were selected to fill in a Risky Behavior Questionnaire for Adolescence (RBQ-A), Family Environment Scale (FES), Center for Epidemiological Survey, Depression Scale (CES-D), Adolescent Self-Rating Life Events Check List (ASLEC), Social Support Scale for Adolescents (SSSA) and self-administered questionnaire. In all the research subjects, 1288 were qualified for the study in April 2011 before the risk factors for non-suicidal self-injury were identified by logistic regression. In 1288 middle school students, 22.67% had a history of non-suicidal self-injury, with 22.70% in boys and 22.64% in girls. 63.36% of students had injured themselves through variously ways, more seen in boys (26.88%) than in girls (11.36%) who cut or burnt themselves. The scores of ASLEC and CES-D in non-suicidal self-injury group appeared higher than that in the control group and the score of SSSA was found higher in the control group. The main risk factors for non-suicidal self-injuries were family conflict, depressive emotion, negative life events and receiving less social support. The prevalence of non-suicidal self-injury among middle school students in Pengzhou was high, which called for more attention.

Significant expression of macrophage migration inhibitory factor and its receptor (CD74) was observed in both the middle ear and inner ear in experimental otitis media in mice. Modulation of macrophage migration inhibitory factor and its signaling pathway might be useful in the management of inner ear inflammation due to otitis media. Inner ear dysfunction secondary to otitis media has been reported. However, the specific mechanisms involved are not clearly understood. The aim of this study is to investigate the expression of macrophage migration inhibitory factor and CD74 in the middle ear and inner ear in lipopolysaccharide-induced otitis media. BALB/c mice received a transtympanic injection of either lipopolysaccharide or phosphate-buffered saline (PBS). The mice were sacrificed 24 h after injection, and temporal bones were processed for polymerase chain reaction (PCR) analysis, histologic examination, and immunohistochemistry. PCR examination revealed that the lipopolysaccharide-injected mice showed a significant up-regulation of macrophage migration inhibitory factor in both the middle ear and inner ear as compared with the PBS-injected control mice. The immunohistochemical study showed positive reactions for macrophage migration inhibitory factor and CD74 in infiltrating inflammatory cells, middle ear mucosa, and inner ear in the lipopolysaccharide-injected mice.

Relating psychological and social factors to academic performance: A longitudinal investigation of high-poverty middle school students.

We investigated the relations between middle school students' psychological factors (academic commitment and emotional control), social perceptions (family involvement and school climate), and academic performance over time. Gender differences in these relations were also examined. Based on a two-year longitudinal data set of 942 middle-school students from a high-poverty district in the United States, we found that all four factors measured in 6th grade were predictive of GPA at the end of the 7th grade above and beyond gender, race, and home intellectual materials. Among these factors, emotional control had the strongest relation with GPA, and the importance of family involvement increased over time, especially for female students. The results also revealed the indirect effects of the social factors on GPA through the psychological factors, and mostly through emotional control. These findings highlight the complex relation between the social-emotional factors and academic outcomes in early adolescence.

Seelman, Katherine D; Werner, Roye

2014-09-01

The competitive market advantages of industry and the balancing force of international governmental organizations (IGOs) are examined to identify market and policy in support of sustainable technology transfer of hearing aids to low and middle income countries. A second purpose is to examine the usefulness of findings for other assistive technologies (AT). Searches of electronic databases, IGO documents, industry reports and journals were supplemented by informal discussions with industry and IGO staff and audiologists. The value chain is used to examine the competitive advantage of industry and the balancing tools of certain IGOs. Both industry and IGOs engage in intellectual property (IP) and competition activities and are active in each segment of the hearing aid value chain. Their market and policy objectives and strategies are different. IGOs serve as balancing forces for the competitive advantages of industry. The hearing aid market configuration and hearing aid fitting process are not representative of other AT products but IP, trade and competition policy tools used by IGOs and governments are relevant to other AT. The value chain is a useful tool to identify the location of price mark-ups and the influence of actors. Market factors and reimbursement and subsidization policies drive hearing aid innovation. UN-related international government organization activities are responsive to the needs of disability populations who cannot afford assistive technology. Policy tools used by international governmental organizations are applicable across assistive technology. A partnership model is important to distribution of hearing aids to low and middle income countries.

The present study examined influences of 6 th grade student-reported parent educational involvement on early adolescent peer group affiliations at 7 th and 8 th grade. In addition, student gender and ethnicity were explored as possible moderators. Drawn from a large effectiveness trial, participants in this study were 5,802 early adolescents across twenty middle schools in the Northwest region of the United States. Findings suggested that specifically parent's educational involvement in 6 th grade predicted increases in positive peer affiliation, when controlling for a general score of parent monitoring practices. The relation between parent educational involvement and peer affiliation varied by student ethnicity but not by gender. Findings suggest the social benefits of parent's engagement with the school context on early adolescent development.

Restoration of long-term potentiation in middle-aged hippocampus after induction of brain-derived neurotrophic factor. J Neurophysiol 96: 677-685, 2006. First published May 17, 2006; doi:10.1152/jn.00336.2006. Restoration of neuronal viability and synaptic plasticity through increased trophic support is widely regarded as a potential therapy for the cognitive declines that characterize aging. Previous studies have shown that in the hippocampal CA1 basal dendritic field deficits in the stabilization of long-term potentiation (LTP) are evident by middle age. The present study tested whether increasing endogenous brain-derived neurotrophic factor (BDNF) could reverse this age-related change. We report here that in middle-aged (8- to 10-mo-old) rats, in vivo treatments with a positive AMPA-type glutamate receptor modulator both increase BDNF protein levels in the cortical telencephalon and restore stabilization of basal dendritic LTP as assessed in acute hippocampal slices 18 h after the last drug treatment. These effects were not attributed to enhanced synaptic transmission or to facilitation of burst responses used to induce LTP. Increasing extracellular levels of BDNF by exogenous application to slices of middle-aged rats was also sufficient to rescue the stabilization of basal dendritic LTP. Finally, otherwise stable LTP in ampakine-treated middle-aged rats can be eliminated by infusion of the extracellular BDNF scavenger TrkB-Fc. Together these results indicate that increases in endogenous BDNF signaling can offset deficits in the postinduction processes that stabilize LTP. PMID:16707719

Eimeria infections are common in cattle worldwide, however, little is known about the invasion dynamics of this unicellular parasite. Therefore, the aim of this study was to analyze intrinsic (host age) and extrinsic (herd size and management system) factors influencing the dynamics of Eimeria spp. found in calves from CE Poland. Fecal samples were collected from 356 calves from different types of management systems and from different herd sizes. Flotation and McMaster method were used for parasitological investigation. Oocysts were differentiated on the basis of morphological criteria. Eight Eimeria species were identified and mean species richness (MSR) was significantly affected by host age. The highest MSR was noted for middle age animals. There was an association between species, with a highly significant co-occurrence of Eimeria bovis with Eimeria zuernii. The presence of E. bovis significantly increased the percentage of individuals carrying E. zuernii. The presence of E. bovis significantly increased the percentage of individuals carrying Eimeria canadensis. The overall prevalence of Eimeria spp. reached 52.8% and was significantly affected by the age of cows, with the highest prevalence in animals between 5-10 months old. The most prevalent species were E. bovis (37.4%), E. zuernii (19.9%) and E. canadensis (12.1%). The prevalence of E. bovis was affected by host age (the highest prevalence in age class 2 animals) and management type (the highest prevalence in individuals raised in groups). The prevalence of E. zuernii was affected by age (the lowest prevalence was noted in the oldest individuals) and herd size (individuals infected were present only in the middle and large size herds), whereas the prevalence of E. canadensis was affected by all three factors. Overall, mean OPG of the combined Eimeria spp. was 458.84 (37.93) and differed significantly between age classes. Mean OPGs were generally low for young and mature animals but high for middle age

Obesity and aging are associated with hypothalamic inflammation, hyperphagia and abnormalities in the thermogenesis control. It has been demonstrated that the association between aging and obesity induces hypothalamic inflammation and metabolic disorders, at least in part, through the atypical hypothalamic transforming growth factor-β (TGF-β1). Physical exercise has been used to modulate several metabolic parameters. Thus, the aim of this study was to evaluate the impact of chronic exercise on TGF-β1 expression in the hypothalamus of Middle-Aged mice submitted to a one year of high-fat diet (HFD) treatment. We observed that long-term of HFD-feeding induced hypothalamic TGF-β1 accumulation, potentiated the hypothalamic inflammation, body weight gain and defective thermogenesis of Middle-Aged mice when compared to Middle-Aged animals fed on chow diet. As expected, chronic exercise induced negative energy balance, reduced food consumption and increasing the energy expenditure, which promotes body weight loss. Interestingly, exercise training reduced the TGF-β1 expression and IkB-α ser32 phosphorylation in the hypothalamus of Middle-Aged obese mice. Taken together our study demonstrated that chronic exercise suppressed the TGF-β1/IkB-α axis in the hypothalamus and improved the energy homeostasis in an animal model of obesity-associated to aging.

To better understand Australia-dwelling Middle Eastern women's lack of service utilization in cardiovascular health, we undertook a study to investigate their understandings and meanings of cardiovascular disease (CVD) and its risk factors. Eight focus groups were conducted in community settings with Turkish, Persian, and Arab women. We found that the women understated their risk of CVD, faced many barriers in reducing their risks, and perceived stress as the most significant contributor to CVD. Women described their stress as primarily emanating from issues surrounding migration and acculturation. Implications for development and delivery of tailored health interventions for Middle Eastern women are discussed.

To examine the influence of state laws and district policies on district-wide elementary school and middle school practices related to physical education (PE) time and the percentage of moderate-to-vigorous physical activity (MVPA) time during PE. Multivariate, cross-sectional analysis of state laws, district wellness and PE policies, and district PE practices for school year 2010-2011 controlling for district-level urbanicity, region, size, race/ethnicity of students, and socioeconomic status and clustered on state. One hundred ninety-five public school districts located in 42 states. District-level PE coordinators for the included districts who responded to an online survey. Minutes and days of PE per week and percent time spent in MVPA during PE time. District PE coordinators reported significantly less PE time than national standards-82.9 and 189.6 minutes at the elementary school and middle school levels, respectively. Physical education was provided an average of 2.5 and 3.7 days per week, respectively; and the percentage of MVPA time in PE was 64.4% and 65.7%, respectively. At the elementary school level, districts in either states with laws governing PE time or in a state and district with a law/policy reported significantly more days of PE (0.63 and 0.67 additional days, respectively), and districts in states with PE time laws reported 18 more minutes of PE per week. At the middle school level, state laws were associated with 0.73 more days of PE per week. Neither state laws nor district policies were positively associated with percent MVPA time in PE. State laws and district policies can influence district-level PE practices-particularly those governing the frequency and duration of PE-although opportunities exist to strengthen PE-related laws, policies, and practices.

Influences of Relative Sea-Level Rise and Mississippi River Delta Plain Evolution on the Holocene Middle Amite River, Southeastern Louisiana

USGS Publications Warehouse

Autin, W.J.

1993-01-01

The Holocene geomorphic history of southeastern Louisiana's middle Amite River is recorded in the stratigraphy of three alloformations, identified in decreasing age as the Watson (WAT), Denham Springs (DS), and Magnolia Bridge (MAG). The WAT meander belt formed by at least 9000 yr B.P., when sea level was lower and the Amite River was tributary to a larger ancestral drainage basin. The DS became an active meander belt by at least 3000 yr B.P., in response to relative sea-level rise and eastward progradation of the Mississippi River delta plain. The MAG developed its meander belt, in part, during the European settlement of the drainage basin, and is now attempting to adjust to modern anthropogenic influences. Geomorphic influences on the middle Amite River floodplain have temporal and spatial components that induce regional- and local-scale effects. Regional extrinsic influences caused meander belt avulsion that produced alloformations. However, local influences produced intrinsic geomorphic thresholds that modified channel morphology within a meander belt but did not induce alloformation development. Base-level influences of the relative sea-level rise and the Mississippi River delta plain were so dominant that the effects of possible climate change were not recognized in the Holocene Amite River system.

The rate of successful health care innovation implementation is dismal. Middle managers have a potentially important yet poorly understood role in health care innovation implementation. This study used self-administered surveys and interviews of middle managers in health centers that implemented an innovation to reduce health disparities to address the questions: Does middle managers' commitment to health care innovation implementation influence implementation effectiveness? If so, in what ways does their commitment influence implementation effectiveness? Although quantitative survey data analysis results suggest a weak relationship, qualitative interview data analysis results indicate that middle managers' commitment influences implementation effectiveness when middle managers are proactive. Scholars should account for middle managers' influence in implementation research, and health care executives may promote implementation effectiveness by hiring proactive middle managers and creating climates in which proactivity is rewarded, supported, and expected.

2016-12-09

Access to affordable and effective health care is a challenge in low- and middle- income countries. Out-of-pocket expenditure for health care is a major cause of impoverishment. One way to facilitate access and overcome catastrophic expenditure is through a health insurance mechanism, whereby risks are shared and financial inputs pooled by way of contributions. This study examined factors that influenced the enrolment status of dairy farmers in Western Kenya to a community health insurance (CHI) scheme. Quantitative, cross-sectional research was used to describe factors influencing the enrolment in the CHI scheme. Quota and convenience sampling was used, recruiting a sample of 135 farmers who supply milk to a dairy cooperation. Data were collected using a structured interview schedule and analysed using Stata SE, Data Analysis and Statistical Software, Version 12. Factors influencing non-enrolment were identified as affordability (40%; n = 47), unfamiliarity with the management of the scheme (37%; n = 44) and a lack of understanding about the scheme (41%; n = 48). An exploratory factor analysis was used to reduce the variables to two factors: information provision and understanding community health insurance (CHI). Logistic regression identified factors associated with enrolment in the Tanykina Community Healthcare Plan (TCHP). Supplies of less than six litres of milk per day (OR: 0.22; 95% CI: 0.06-0.84) and information provision (OR: 8.77; 95% CI: 2.25-34.16) were significantly associated with enrolment in the TCHP. Nearly 30% (29.6%; n = 40) of the respondents remarked that TCHP is expensive and 17% (n = 23) asked for more education on CHI and TCHP in an open-ended question. Recommendations related to marketing strategies, financial approach, information provision and further research were outlined to be made to the management of the TCHP as well as to those involved in public health.

To determine the prevalence of dyslipidemia in students from the primary and middle schools and the influential factors, and to provide evidence for the prevention and control of dyslipidemia and relevant chronic diseases in primary and middle schools. 
 Methods: A total of 2 028 students aged 7 to 17 from the primary and middle schools in Changsha were selected by stratified random cluster sampling. The contents of the study included questionnaire survey, physical measurement and blood tests for fasting blood triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) levels. Non-high-density lipoprotein cholesterol (non-HDL-C) level was calculated by TC level minus HDL-C level. Chi-square test and non-conditional logistic regression model were used to analyze the factors that contributed to dyslipidemia.
 Results: The dyslipidemia rate was 18.6%, and the abnormal rates of TG, TC, LDL-C, non-HDL-C and HDL-C were 6.8%, 5.6%, 2.3%, 4.2% and 8.6%, respectively. By chi-square test, the dyslipidemia rate in students with different ages, home locations, BMI groups, central obesity, time on watching TV or playing computer per day, and daily sleep time was statistically significant. Non-conditional logistic regression analysis showed that home location for the city (OR=1.332), overweight (OR=1.548), obesity (OR=2.201), central obesity (OR=1.695), watching TV or playing computer for more than 2 hours per day (OR=1.357), daily sleep time longer than 11 hours (OR=2.518) were the risk factors for dyslipidemia in students from the primary and middle schools. 
 Conclusion: Nearly 1/5 primary and middle school students show dyslipidemia, which is associated with obesity and other bad behaviors.

This study was to identify the relationships of trait anger, mode of anger expression, and perceived stress to mental health status in middle aged women. The subjects were 157 middle aged women from 40s to 60s who lived in Seoul. Data was collected by questionnaire surveys using the convenience sampling. The instruments used for this study were Spielberger's trait anger scale and anger expression scale, Cohen, Kamarck, and Mermelstein's perceived stress and Derogatis's SCL-90-R. The collected data was analyzed using descriptive statistics, Pearson correlation coefficient, and Stepwise multiple regression with SAS/PC. The trait anger of middle aged women indicated a significantly positive correlation to perceived stress(r=.180, p=.023) and mental health status(r.=021, p=.014). Anger-in(r=.237, p<.05), and perceived stress(p=.461, p<.01) showed significantly positive correlation to mental health status. The most significant predictor influencing health status of middle aged women was perceived stress, and anger-in and the variance explained was 27%. These results suggested that middle aged women with high degree of trait anger is likely to be high in stress perception. Perceived stress and anger-in are major factors influencing mental health status.

Factors influencing children's food choice.

Although food habits are not stable and unchanging during a person's lifetime, a base for healthy food habits can be created in early childhood. Children's food habits can be assumed to be influenced by their parents' food habits and choices. The aim of this article is to review factors influencing food choice in children as well as in adults. The results demonstrate that the development of children's food habits is influenced by a multitude of factors. Parents play an important role in the formation of food habits and preferences of young children. They can influence their children's food choice by making specific foods available, by acting as models for their children and by their behaviour in specific situations. Children tend to be afraid of new foods and do not readily accept them. However, experience is known to enhance preference, and earlier experiences of a particular food are the major determinants of the development of children's food acceptance patterns. Thus, parents should be encouraged to make healthy foods easily available to the child and serve these foods in positive mealtime situations in order to help their child to develop healthy food habits.

The article is devoted to the study of the impact of the information economy on the formation of the middle class. The paper identifies factors contributing to the increase in the share of the middle class in the transition to the information economy. The positive synergetic influence of telecommunication technologies on the formation of the middle class is considered through a possibility of using virtual spaces for labor and educational activities, a possibility of obtaining high returns in the form of dividends on intellectual capital, a qualitative change in the structure of needs, an access to new types of information services, etc. Authors develop a complex model of research of the middle class in the information economy, differing from those available using an expanded list of criteria. In addition to such widely used criteria as income level, level of education and self-identification, the criterion "degree of involvement in the information society" was introduced. The study substantiates that the transition to the information economy made an access to information and communication technologies one of the most significant criteria for social differentiation of society. On the basis of the model, an econometric estimate of the middle class has been carried out, which makes it possible to reveal the share of the middle class in modern society, dynamics of its development, as well as multicollinearity between spending on education, the Gini coefficient, access to information and telecommunication technologies and the size of the middle class.

Physical activity (PA) promotion is beneficial to gain and maintain optimal health, but might increase risks for physical activity-related injury (PARI). This cross-sectional study aimed to investigate the incidence rate and identify risk factors of PARI among Chinese middle school students. Selected via the method of cluster random sampling, students graded 7⁻8 (junior) and 10⁻11 (senior) from five middle schools (aged from 10 to 18 years old) in Shantou were invited to participate in the survey. Information on socio-demography, PA involvement, sleep duration, individual safety awareness and exercise behavior, and PARI experiences in the past 12 month was collected. Multivariate logistic regression model was performed to estimate the risk factors of PARI. A total of 3082 participants completed the valid questionnaires, with an overall incidence rate of 25.1%. Boys, junior school students, sports team members, and those with lower safety awareness, living with single parent, and without any chronic conditions were at higher risks for PARI. Moreover, exercising on wet floor or with illness frequently would also be more likely to experience injury, especially those with at least 120 min per day. In conclusion, PARI was prevalent among middle school students in southern China. The above data provide insights that were focused and effective actions should be taken to prevent school-aged adolescents from PARI and maximize the benefits of PA.

Physical activity improves health and may delay the onset of several chronic diseases. For women in particular, the rate of these diseases accelerates at middle age; therefore it is important to identify the determinants of health-enhancing physical activity during midlife in this population. In this study, we focused on determinants that are unique to the female sex, such as childbearing and menopause. The main objective was to characterize the level of physical activity and differences between active and inactive middle-aged Finnish women. In addition, we examined the association of physical activity with female reproductive factors at midlife. The study population consisted of 647 women aged 48 to 55 years who participated in our Estrogenic Regulation of Muscle Apoptosis (ERMA) study during the period from 2015 to 2016. Physical activity was measured objectively using hip-worn accelerometers for seven consecutive days. The outcome measures included the amounts of light intensity physical activity and moderate to vigorous intensity physical activity accumulated in bouts of at least 10 minutes (MVPA10). MVPA10 was used to determine whether women were placed in the active (≥150 min/week) or inactive (<150 min/week) group. Multiple linear regression models were performed with physical activity measures as dependent variables and cumulative reproductive history index, menopausal symptoms, and pelvic floor dysfunction as independent variables. We found that a large portion (61%) of Finnish middle-aged women did not meet the physical activity recommendations of 150 minutes of MVPA10 per week. In the studied cohort, 78% of women experienced menopausal symptoms, and 54% exhibited pelvic floor dysfunction. Perceived menopausal symptoms were associated with greater light physical activity. Perceived pelvic floor dysfunction was associated with lower MVPA10. According to the fully adjusted multiple linear regression models, reproductive factors explained 6.0% of the

Surgical anatomy and pathology of the middle ear.

PubMed

Luers, Jan Christoffer; Hüttenbrink, Karl-Bernd

2016-02-01

Middle ear surgery is strongly influenced by anatomical and functional characteristics of the middle ear. The complex anatomy means a challenge for the otosurgeon who moves between preservation or improvement of highly important functions (hearing, balance, facial motion) and eradication of diseases. Of these, perforations of the tympanic membrane, chronic otitis media, tympanosclerosis and cholesteatoma are encountered most often in clinical practice. Modern techniques for reconstruction of the ossicular chain aim for best possible hearing improvement using delicate alloplastic titanium prostheses, but a number of prosthesis-unrelated factors work against this intent. Surgery is always individualized to the case and there is no one-fits-all strategy. Above all, both middle ear diseases and surgery can be associated with a number of complications; the most important ones being hearing deterioration or deafness, dizziness, facial palsy and life-threatening intracranial complications. To minimize risks, a solid knowledge of and respect for neurootologic structures is essential for an otosurgeon who must train him- or herself intensively on temporal bones before performing surgery on a patient. © 2015 Anatomical Society.

Covell, Christine L

2008-07-01

This paper is a report of the development of the middle-range theory of nursing intellectual capital. Rising healthcare costs and advances in technology have contributed to the need for better understanding of the influence of nurses' knowledge, skills and experience on patient and organizational outcomes. The middle-range nursing intellectual capital theory was developed using the strategies of concept and theory derivation. The principles of research synthesis were used to provide empirical support for the propositions of the theory. The middle-range nursing intellectual capital theory was derived from intellectual capital theory to make it relevant and applicable to a specific aspect of nursing, continuing professional development. It proposes that the nursing knowledge available in healthcare organizations is influenced by variables within the work environment, and influences patient and organizational outcomes. The middle-range nursing intellectual capital theory should be tested in different healthcare systems and in different settings and countries to determine its effectiveness in guiding research.

Objectives This study sought to explore whether Native Hawaiian primary ethnic identity is associated with cigarette use among Native Hawaiian middle school students. This study also explored whether social influence, psychosocial and cultural factors are associated with cigarette use in this sample. Design The data are from a cross-sectional survey of 1,695 Native Hawaiian middle school students at 22 public and private schools on five islands in Hawaii. A subset of these students from Native Hawaiian serving schools (N = 136) completed additional measures of Hawaiian cultural variables. Results Based on univariate analyses, students whose primary ethnic identification was Hawaiian were more likely to have tried smoking (p<0.001) and to be current smokers (p<0.05) as compared to those classified as part Hawaiian. However, these findings were no longer significant in multivariate analyses. Social influence variables (i.e. peer and parental smoking) were most influential in explaining both prior and current smoking. Attendance at public school was also an important factor in explaining previous (OR = 2.43; 95% CI = 1.74, 3.38) and current (OR = 7.20; 95% CI = 4.58, 11.32) smoking behavior. Finally, cultural variables such as valuing Hawaiian folklore, customs, activities and lifestyle were largely unassociated with smoking behavior among Native Hawaiian middle school youth. Conclusions Additional research is needed to understand what aspects of ethnic identity are associated with smoking behavior among Native Hawaiian youth. The strong influence of peer and parental smoking suggests the need for interventions that support the creation of social environments that discourage tobacco use. PMID:17454098

1992-10-01

A number of risk factors leading to malnutrition were investigated among 400 mothers of malnourished children in the middle belt of Nigeria. Poverty, family instability, poor environmental sanitation, faulty weaning practices, illiteracy, ignorance, large family size and preventable infections are the main factors responsible for malnutrition. The strategies for intervention are in the area of health education emphasizing the importance of breastfeeding, family stability, responsible parenthood and small family sizes through culturally acceptable family planning methods. There is need to improve weaning methods through nutrition education, growth monitoring and food demonstration with community participation. Political will is needed to improve literacy status, farming methods and general living conditions.

Factors influencing perceived angular velocity.

PubMed

Kaiser, M K; Calderone, J B

1991-11-01

The assumption that humans are able to perceive and process angular kinematics is critical to many structure-from-motion and optical flow models. The current studies investigate this sensitivity, and examine several factors likely to influence angular velocity perception. In particular, three factors are considered: (1) the extent to which perceived angular velocity is determined by edge transitions of surface elements, (2) the extent to which angular velocity estimates are influenced by instantaneous linear velocities of surface elements, and (3) whether element-velocity effects are related to three-dimensional (3-D) tangential velocities or to two-dimensional (2-D) image velocities. Edge-transition rate biased angular velocity estimates only when edges were highly salient. Element velocities influenced perceived angular velocity; this bias was related to 2-D image velocity rather than 3-D tangential velocity. Despite these biases, however, judgments were most strongly determined by the true angular velocity. Sensitivity to this higher order motion parameter was surprisingly good, for rotations both in depth (y-axis) and parallel to the line of sight (z-axis).

The study explored the influence of university-based teacher education courses on pre-service middle and high school teachers’ experiences with multicultural themes in a secondary science alternative certification program. Eight participants ( N = 8), six women and two men, volunteered to be a part of the study that took place over a period of four semesters. Qualitative data was collected, coded and analyzed to make meaning of the participants’ experiences. Data comprised of participants’ reflective journals, personal and group interviews, and classroom observations done in middle school practicum and high school student teaching placements. The findings indicated that while the participants became more familiar with the themes of multicultural education, many did not demonstrate fluency with these themes and struggled with balancing their responsibilities as a science teacher and a culturally competent teacher.

To examine factors influencing intensive care unit (ICU) survival for critically ill elderly patients and to compare survivors and nonsurvivors of ICU on demographic and illness-related variables. Retrospective, ex post facto research design. Adult medical and surgical ICUs. The records of 164 survivors and 111 nonsurvivors from 2 medical-surgical ICUs were examined. Patients were placed into 3 age groups (middle-aged, young-old, and old-old) to compare outcomes for elderly ICU patients. ICU survival, ICU treatments received, severity of illness. The Acute Physiology Age and Chronic Health Evaluation II (APACHE II) was used to assess illness severity. Additional illness-related information was collected by chart review. Predictors of ICU nonsurvival were severity of illness (measured by APACHE II scores) and intubation. Comparison of survivors and nonsurvivors revealed no statistically significant differences in sex or age. For all age groups, nonsurvivors had significantly higher mean days of ICU hospitalization (F (1,239) = 7.20 P < .0078) and higher APACHE II scores (F (1,239) = 106.5 P < .0001). Analysis of ICU treatments received by the 3 age groups of survivors revealed a significant difference only on oxygen therapy, (chi-square = 10.2, df = 2, P = .006), with more young-old (aged 65 to 79) and old-old (aged 80 and older) ICU patients receiving oxygen therapy than middle-aged patients (aged 45 to 64). The findings of this study demonstrated that severity of illness was a predictor of ICU outcome; age was not. Additionally, age was not related to ICU treatments received.

2001-11-01

This study aims to explore the relationship between socio-psychological stress and low back pain (LBP) prevalence among Chinese middle-aged women. Women in mid-life experience increasing socio-psychological stress because of midlife transitions, stressful life events and housework or work factors. Encountering socio-psychological stress itself may result in the manifestation of LBP. A case-control study of Hong Kong community-based middle-aged women was conducted. The study subjects were either from the University Family Medicine Clinic or from a previous population-based cross-sectional study of middle-aged women conducted by Department of Community and Family Medicine. Among the 928 potential eligible subjects from both sources, a total of 182 cases and 235 controls participated in this study. Data were collected from face-to-face interviews and included demographic factors, menopausal status, socio-psychological stress and occurrence of LBP. Socio-psychological stress covered social factors, self-reported nature of housework/work, housework/work stress and stressful life events. Among the 182 cases who entered this study, 83 women (45.6%) had experienced 1-<14 days of LBP, and 99 women (54.4%) had at least 14 days of LBP in the previous 12 months. Those who reported that 'their family members, relatives or friends were very sick, died, needed her to take care of them or who they worried about in the past 12 months' had an increased risk of LBP of 67% (95% confidence interval (CI) 1.09-2.55). In addition women with a bad or ordinary relationship with cohabitants had an increased risk of LBP of 70% (95% CI 1.00-3.04). Lastly, women with a high housework or work stress had an increased risk of suffering both types of LBP of nearly two- and half-fold (95% CI 1.61-3.85). The results indicate that an association exists between high socio-psychological stress and LBP prevalence. Alleviating the impact of housework or work related factors would, however, involve

Objectives Social factors have profound effects on health. Children are especially vulnerable to social influences, particularly in their early years. Adverse social exposures in childhood can lead to chronic disorders later in life. Here, we sought to identify and evaluate the impact of social factors on child health in Ghana. As Ghana is unlikely to achieve the Millennium Development Goals’ target of reducing child mortality by two-thirds between 1990 and 2015, we deemed it necessary to identify social determinants that might have contributed to the non-realisation of this goal. Methods ScienceDirect, PubMed, MEDLINE via EBSCO and Google Scholar were searched for published articles reporting on the influence of social factors on child health in Ghana. After screening the 98 articles identified, 34 of them that met our inclusion criteria were selected for qualitative review. Results Major social factors influencing child health in the country include maternal education, rural-urban disparities (place of residence), family income (wealth/poverty) and high dependency (multiparousity). These factors are associated with child mortality, nutritional status of children, completion of immunisation programmes, health-seeking behaviour and hygiene practices. Conclusions Several social factors influence child health outcomes in Ghana. Developing more effective responses to these social determinants would require sustainable efforts from all stakeholders including the Government, healthcare providers and families. We recommend the development of interventions that would support families through direct social support initiatives aimed at alleviating poverty and inequality, and indirect approaches targeted at eliminating the dependence of poor health outcomes on social factors. Importantly, the expansion of quality free education interventions to improve would-be-mother’s health knowledge is emphasised. PMID:26745277

Factors that may have influenced aminoglycoside use and expenditure in one hospital were examined. Factors that were evaluated as to their influence on aminoglycoside-use patterns were: (1) formulary status; (2) bacterial susceptibility patterns; (3) identified or perceived differences in toxicity; (4) changes in patient population; (5) price paid by the hospital for aminoglycosides; (6) distribution of newsletters or memoranda; (7) advertising and detailing; and (8) pharmacy policies. For FY 1976-77 to 1979-80, the largest proportion of aminoglycoside expense was for gentamicin. During FY 1980-81, the expenditure for gentamicin decreased and tobramycin accounted for the largest proportion of total expenditure. Monthlymore » gentamicin use decreased 20% during FY 1980-81 from the previous year. Tobramycin use increased from January 1979 to November 1980 and decreased from December 1980 to June 1981. Kanamycin use and amikacin use were fairly constant during the study period. Based on temporal relationships, the following factors appeared to influence aminoglycoside use and expenditure: (1) a study conducted at the institution from June 1977 to June 1979 comparing gentamicin and tobramycin nephrotoxicity; (2) a comparative nephrotoxicity study published in a widely circulated medical journal in May 1980; and (3) an intramural newsletter and memorandum distributed in March 1981 encouraging selective aminoglycoside use. The identification of factors that potentially influenced aminoglycoside use can be used to anticipate the future impact of similar events and to devise strategies to influence antimicrobial use.« less

To determine epidemiology of cardiovascular risk factors according to geographic distribution and macrolevel social development index among urban middle class subjects in India. We performed cross-sectional surveys in 11 cities in India during years 2005-2009. 6198 subjects aged 20-75 years (men 3426, women 2772, response 62%) were evaluated for cardiovascular risk factors. Cities were grouped according to geographic distribution into northern (3 cities, n = 1321), western (2 cities, n = 1814), southern (3 cities, n = 1237) and eastern (3 cities, n = 1826). They were also grouped according to human social development index into low (3 cities, n = 1794), middle (5 cities, n = 2634) and high (3 cities, n = 1825). Standard definitions were used to determine risk factors. Differences in risk factors were evaluated using χ(2) test. Trends were examined by least squares regression. Age-adjusted prevalence (95% confidence intervals) of various risk factors was: low physical activity 42.1% (40.9-43.3), high dietary fat 49.9% (47.8-52.0), low fruit/vegetables 26.9% (25.8-28.0), smoking 10.1% (9.1-11.1), smokeless tobacco use 9.8% (9.1-10.5), overweight 42.9% (41.7-44.1), obesity 11.6% (10.8-12.4), high waist circumference 45.5% (44.3-46.7), high waist-hip ratio 75.7% (74.7-76.8), hypertension 31.6% (30.4-32.8), hypercholesterolemia 25.0% (23.9-26.9), low HDL cholesterol 42.5% (41.3-43.7), hypertriglyceridemia 36.9% (35.7-38.1), diabetes 15.7% (14.8-16.6), and metabolic syndrome 35.7% (34.5-36.9). Compared with national average, prevalence of most risk factors was not significantly different in various geographic regions, however, cities in eastern region had significantly lower prevalence of overweight, hypertension, hypercholesterolemia, diabetes and metabolic syndrome compared with other regions (P < 0.05 for various comparisons).

This study examined the relationships between youth and parental sensation-seeking, peer influence, parental monitoring and youth risk involvement in adolescence using structural equation modeling. Beginning in grade-six, longitudinal data were collected from 543 students over three years. Youth sensation-seeking in grade six contributed to risk involvement in early adolescence (grades six and seven) indirectly through increased peer risk influence and decreased parental monitoring but did not have a direct contribution. It contributed directly and indirectly to risk involvement in middle adolescence (grades eight and nine). Parent sensation-seeking at baseline was positively associated with peer risk influence and negatively associated with parental monitoring; it had no direct effect on adolescent risk involvement. Parental monitoring buffers negative peer influence on adolescent risk involvement. Results highlight the need for intervention efforts to provide normative feedback about adolescent risky behaviors and to vary among families in which parents and/or youth have high sensation-seeking propensities.

The societal demand for inspiring and engaging science, technology, engineering, and mathematics (STEM) students and preparing our workforce for the emerging creative economy has necessitated developing students' self-efficacy and understanding of engineering design processes from as early as elementary school levels. Hands-on engineering design activities have shown the potential to promote middle school students' self-efficacy and understanding of engineering design processes. However, traditional classrooms often lack hands-on engineering design experiences, leaving students unprepared to solve real-world design problems. In this study, we introduce the framework of a toy design workshop and investigate the influence of the workshop activities on students' understanding of and self-efficacy beliefs in engineering design. Using a mixed method approach, we conducted quantitative analyses to show changes in students' engineering design self-efficacy and qualitative analyses to identify students' understanding of the engineering design processes. Findings show that among the 24 participants, there is a significant increase in students' self-efficacy beliefs after attending the workshop. We also identified major themes such as design goals and prototyping in students' understanding of engineering design processes. This research provides insights into the key elements of middle school students' engineering design learning and the benefits of engaging middle school students in hands-on toy design workshops.

Background Research is needed to identify early life risk factors associated with different developmental paths leading to overweight by adolescence. Objectives To model heterogeneity in overweight development during middle childhood and identify factors associated with differing overweight trajectories. Methods Data was drawn from the Quebec Longitudinal Study of Child Development (QLSCD; 1998-2010). Trained research assistants measured height and weight according to a standardized protocol and conducted yearly home interviews with the child’s caregiver (mother in 98% of cases). Information on several putative early life risk factors for the development of overweight were obtained, including factors related to the child’s perinatal, early behavioral family and social environment. Group-based trajectories of the probability of overweight (6-12 years) were identified with a semiparametric method (n=1678). Logistic regression analyses were used to identify early risk factors (5 months- 5 years) associated with each trajectory. Results Three trajectories of overweight were identified: “early-onset overweight” (11.0 %), “late-onset overweight” (16.6%) and “never overweight” (72.5%). Multinomial analyses indicated that children in the early and late-onset group, compared to the never overweight group, had 3 common types of risk factors: parental overweight, preschool overweight history, and large size for gestational age. Maternal overprotection (OR= 1.12, CI: 1.01-1.25), short nighttime sleep duration (OR=1.66, CI: 1.07-2.57), and immigrant status (OR=2.01, CI: 1.05-3.84) were factors specific to the early-onset group. Finally, family food insufficiency (OR=1.81, CI: 1.00-3.28) was weakly associated with membership in the late-onset trajectory group. Conclusions The development of overweight in childhood follows two different trajectories, which have common and distinct risk factors that could be the target of early preventive interventions.

There is a need for a better understanding of exactly how organizational management factors at a nuclear power plant (NPP) affect plant safety performance, either directly or indirectly, and how these factors might be observed, measured, and evaluated. The purpose of this research project is to respond to that need by developing a general methodology for characterizing these organizational and management factors, systematically collecting information on their status and integrating that information into various types of evaluative activities. Research to date has included the development of the Nuclear Organization and Management Analysis Concept (NOMAC) of a NPP, the identification ofmore » key organizational and management factors, and the identification of the methods for systematically measuring and analyzing the influence of these factors on performance. Most recently, two field studies, one at a fossil fuel plant and the other at a NPP, were conducted using the developed methodology. Results are presented from both studies highlighting the acceptability, practicality, and usefulness of the methods used to assess the influence of various organizational and management factors including culture, communication, decision-making, standardization, and oversight. 6 refs., 3 figs., 1 tab.« less

The decision by prosthodontic residency program directors to employ the Match process highlights the need to understand applicant priorities that influence their choice of which programs to rank highly. The purpose of this study is to determine the factors that were most important to residents when choosing from among nonmilitary based prosthodontics dental residency programs in the United States. Following completion of a pilot study, all currently enrolled prosthodontic residents at nonmilitary residency programs were invited to participate via the internet. The study consisted of a survey instrument asking residents to rank 26 possible factors that might impact an applicant's choice of residency program. In addition, the instrument collected other possible influencing variables including gender and debt load. Mean rank scores were compared to determine the most and least important factors. Kruskal-Wallis test was used to compare specific factors between the possible influencing variables. Two hundred and thirty residents completed the survey instrument, representing a 54.1% response rate of possible participants. With regard to factors influencing program choice, reputation of the residency program was the factor ranked the highest by participants, followed in descending order by the program director's personality, curriculum content, access to use of the latest digital technology, and opportunities for dental implant placement. Quality of schools for children, community outreach opportunities, and the ability to moonlight were ranked as the least important factors. Male and female residents ranked factors such as tuition/stipend, curriculum content, and community outreach opportunities significantly differently. Depending on debt load, residents ranked the factors tuition/stipend, ability to moonlight, curriculum content, and safety of the area where the program is differently. Current prosthodontic residents valued the reputation of the program as the most

Objective The aim of the present study was to explore prominent factors affecting turnover intentions among public hospital doctors in urban areas, particularly in Xiangyang City, Hubei Province, a middle-level city in central China. Methods Questionnaires were used to collect data from 284 public hospital doctors. Pearson's Chi-squared was used to assess whether sociodemographic and other factors were related to the turnover intentions of public hospital doctors. Binary logistic regression was performed to determine the significant factors that influence turnover intentions. Results The analysis revealed that 28.2% of public hospital doctors intended to leave the hospital where they were currently employed. Dissatisfaction with working conditions and hospital management processes, as well as work pressures, were significant factors contributing to the turnover intentions of public hospital doctors. Conclusion Research into turnover intentions indicates that public hospital doctors surveyed in urban China give greater weight to their professional environment and career development rather than salary in their employment decisions. What is known about the topic? Turnover of medical staff is a concern to hospital administrators because it is costly and detrimental to organisational performance and quality of care. Most studies have focused on the effects of individual and organisational factors on nurses' intentions to leave their employment. Income dissatisfaction was one of the determining factors of turnover intentions in previous studies. What does this paper add? The satisfaction of public hospital doctors with regard to income is not a determining factor of turnover intentions. In contrast with findings of previous studies, the doctors in public hospitals in urban China in the present study gave greater weight to their professional environment and career development in their employment decisions. What are the implications for practitioners? The findings suggest

We cross-sectionally analyzed the association between duration of physical activity and the presence of selected cardiovascular risk factors in the middle-aged male personnel of the Self-Defense Forces who underwent retirement check-up (n = 974). In a univariate regression analysis, duration of high intensity physical activity but not that of moderate or low intensity physical activity inversely correlated with body mass index (BMI), triglyceride, fasting plasma glucose, white blood cell (WBC) count and systolic blood pressure. No intensity categories of physical activity correlated with total cholesterol. In a multivariate logistic regression analysis adjusted for lifestyle factors and the rank, the odds ratio per 1 h/wk increase in high intensity physical activity was .88 (95% confidence interval (CI) .80-.97; P=.007) for the presence of obesity (BMI 25.0 kg/m2), .88 (95% CI .81-.95; P = .002) for hypertrigly ceridemia, .87 (95% CI .76-.99; P=.034) for type 2 diabetes, and .90 (95% CI .82-.99; P=.037) for hypertension. Neither hypercholesterolemia nor high WBC count (> or = 6,900/microl) was associated with high intensity physical activity. High intensity physical activity inversely correlated with traditional cardiovascular risk factors in the middle-aged men.

Triathlon is a multisport event consisting of sequential swim, cycle, and run disciplines performed over a variety of distances. This complex and unique sport requires athletes to appropriately distribute their speed or energy expenditure (ie, pacing) within each discipline as well as over the entire event. As with most physical activity, the regulation of pacing in triathlon may be influenced by a multitude of intrinsic and extrinsic factors. The majority of current research focuses mainly on the Olympic distance, whilst much less literature is available on other triathlon distances such as the sprint, half-Ironman, and Ironman distances. Furthermore, little is understood regarding the specific physiological, environmental, and interdisciplinary effects on pacing. Therefore, this article discusses the pacing strategies observed in triathlon across different distances, and elucidates the possible factors influencing pacing within the three specific disciplines of a triathlon.

Europe has a growing population of ethnic minority groups whose dietary behaviours are potentially of public health concern. To promote healthier diets, the factors driving dietary behaviours need to be understood. This review mapped the broad range of factors influencing dietary behaviour among ethnic minority groups living in Europe, in order to identify research gaps in the literature to guide future research. A systematic mapping review was conducted (protocol registered with PROSPERO 2014: CRD42014013549). Nine databases were searched for quantitative and qualitative primary research published between 1999 and 2014. Ethnic minority groups were defined as immigrants/populations of immigrant background from low and middle income countries, population groups from former Eastern Bloc countries and minority indigenous populations. In synthesizing the findings, all factors were sorted and structured into emerging clusters according to how they were seen to relate to each other. Thirty-seven of 2965 studies met the inclusion criteria (n = 18 quantitative; n = 19 qualitative). Most studies were conducted in Northern Europe and were limited to specific European countries, and focused on a selected number of ethnic minority groups, predominantly among populations of South Asian origin. The 63 factors influencing dietary behaviour that emerged were sorted into seven clusters: social and cultural environment (16 factors), food beliefs and perceptions (11 factors), psychosocial (9 factors), social and material resources (5 factors), accessibility of food (10 factors), migration context (7 factors), and the body (5 factors). This review identified a broad range of factors and clusters influencing dietary behaviour among ethnic minority groups. Gaps in the literature identified a need for researchers to explore the underlying mechanisms that shape dietary behaviours, which can be gleaned from more holistic, systems-based studies exploring relationships between

The objectives of the current study are to investigate the spatial, temperal variation of phisphorus (P) fraction in middle reaches of the Yarlung Zangbo River of China. Samples were collected in April (dry season), August (wet season), and Octber (normal season) along with the middle reaches from Lazi site to Nuxia sitewhich which is about 1000km long. Sequential extraction were applied to determine the forms of phosphorus in suspended particles and to assess the potential bioavailability of particulate P. The results indicated that the distribution of suspended particle size inflenced not only the total phosphorus concentration, but also the proportions of different forms of phosphorus. The exchangeable phosphorus (Ex-P), Fe-bound-P, Ca-bound-P were the most aboundant forms and the highest proportions of total P. The total P concentrations were closely relative to the concentration of suspended particles. According to the characteristics of suspended particles in the Yarlung Zangbo River, the relationship between the suspended particles size and species of phosphorus was established though statistical analysis. The Ex-P increased with the decreasing of suspended particulate size. The content of bioavailable particulate phosphorus varied greatly with the proportions of particulate size. In genral, the higher the proportion of smaller particle size, the higher the content of bioavailable phosphorus. The main factors which affect the phosphorus transportation in Yarlung Zangbo River had also been discussed.

Cigarette smoking is a common tobacco use which is the leading preventable cause of death in Thailand. Prevalence and risk factors of cigarette smoking are varied amongst communities. The present study aimed to determine the prevalence and associated risk factors of cigarette smoking amongst middle-school students studying in the Ongkharak district, central Thailand. A cross-sectional survey was conducted with students of the public schools in Ongkharak district, central Thailand, in 2013. Of 677 middle-school students (grade 7-9) who currently enrolled in the classes, 130 were randomly selected. Data on smoking as well as demographic characteristics were collected using an anonymous self- administered questionnaire which was modified from the 2013 Middle School Youth Risk Behavior Survey (YRBS) and translated into Thai. The prevalence of children who smoked or had smoked before was 24.6% (38.9% amongst males and 6.9% amongst females, p-value < 0.001), of this proportion 50% were current smokers. Logistic regression analysis showed that the risk factors for having ever smoked were being male (OR = 7.63, 95% CI 2.26-26.90), of an older age (OR = 2.30, 95% CI 1.40-3.76), high coffee or tea consumption (OR = 2.95, 95% CI 1.08-8.05) and sharing a household with a smoker (OR = 2.96, 95% CI 1.09-8.06). Those who have smoked reported higher prevalence of asthma compared to those who have never smoked (25.0% vs. 9.2%, p-value = 0.033). About a quarter ofmiddle-school students in Ongkharak district smoked cigarettes. Anti-smoking and prevention policies should be encouraged to tackle this rising major public health problem.

Informal science learning has been found to have effects on students' science learning. Through the use of secondary data from a national assessment of 7410 middle school students in China, this study explores the relationship among five types of extracurricular science activities, learning interests, academic self-concept, and science achievement. Structural equation modelling was used to investigate the influence of students' self-chosen and school-organised extracurricular activities on science achievement through mediating interests and the academic self-concept. Chi-square tests were used to determine whether there was an opportunity gap in the student's engagement in extracurricular activities. The students' volunteer and school-organised participation in extracurricular science activities had a positive and indirect influence on their science achievement through the mediating variables of their learning interests and academic self-concept. However, there were opportunity gaps between different groups of students in terms of school location, family background, and especially the mother's education level. Students from urban areas with better-educated mothers or higher socioeconomic status are more likely to access diverse science-related extracurricular activities.

Increased urbanization in the developing world parallels a rising burden of chronic diseases. Developing countries account for ∼ 80% of global cardiovascular (CV) deaths, but contribute a paucity of systematic epidemiological data on CV risk factors. To estimate the prevalence of CV risk factors in rural and urban cohorts attending general practice clinics in the Africa and Middle East (AfME) region. In a cross-sectional epidemiological study, the presence of CV risk factors (hypertension, diabetes mellitus (diabetes), dyslipidemia, obesity, smoking and abdominal obesity) were evaluated in stable adult outpatients attending general practice primary care clinics. A rural population was defined as isolated (>50 km or lack of easy access to commuter transportation) from urban centers. 4,378 outpatients were systematically recruited from 94 clinics across 14 AfME countries. Mean age was 46 ± 14 years and 52% of outpatients were female. A high prevalence of dyslipidemia (70%) and abdominal obesity (68%) were observed, followed by hypertension (43%) and diabetes (25%). The vast majority of outpatients (92%) had at least one modifiable CV risk factor, many (74%) had more than one, and half (53%) had 3 or more. These findings were observed in both genders and across urban and rural centers. Among outpatients with pre-existing hypertension or dyslipidemia, many were not at their target blood pressure or LDL-cholesterol goals. Cardiovascular risk factors are highly prevalent among relatively young, stable outpatients attending general practice clinics across AfME. The findings support opportunistic screening for CV risk factors whenever outpatients visit a general practitioner and provide an opportunity for early identification and management of CV risk factors, including lifestyle interventions.

It is not clear what effect socioeconomic factors have on adherence to antiretroviral therapy (ART) among patients in low- and middle-income countries.  We performed a systematic review of the association of socioeconomic status (SES) with adherence to treatment of patients with HIV/AIDS in low- and middle-income countries. We searched electronic databases to identify studies concerning SES and HIV/AIDS and collected data on the association between various determinants of SES (income, education, occupation) and adherence to ART in low- and middle-income countries. From 252 potentially-relevant articles initially identified, 62 original studies were reviewed in detail, which contained data evaluating the association between SES and adherence to treatment of patients with HIV/AIDS. Income, level of education, and employment/occupational status were significantly and positively associated with the level of adherence in 15 studies (41.7%), 10 studies (20.4%), and 3 studies (11.1%) respectively out of 36, 49, and 27 studies reviewed. One study for income, four studies for education, and two studies for employment found a negative and significant association with adherence to ART. However, the aforementioned SES determinants were not found to be significantly associated with adherence in relation to 20 income-related (55.6%), 35 education-related (71.4%), 23 employment/occupational status-related (81.5%), and 2 SES-related (100%) studies. The systematic review of the available evidence does not provide conclusive support for the existence of a clear association between SES and adherence to ART among adult patients infected with HIV/AIDS in low- and middle-income countries. There seems to be a positive trend among components of SES (income, education, employment status) and adherence to antiretroviral therapy in many of the reviewed studies. PMID:23930333

Restoration of neuronal viability and synaptic plasticity through increased trophic support is widely regarded as a potential therapy for the cognitive declines that characterize aging. Previous studies have shown that in the hippocampal CA1 basal dendritic field deficits in the stabilization of long-term potentiation (LTP) are evident by middle age. The present study tested whether increasing endogenous brain-derived neurotrophic factor (BDNF) could reverse this age-related change. We report here that in middle-aged (8- to 10-mo-old) rats, in vivo treatments with a positive AMPA-type glutamate receptor modulator both increase BDNF protein levels in the cortical telencephalon and restore stabilization of basal dendritic LTP as assessed in acute hippocampal slices 18 h after the last drug treatment. These effects were not attributed to enhanced synaptic transmission or to facilitation of burst responses used to induce LTP. Increasing extracellular levels of BDNF by exogenous application to slices of middle-aged rats was also sufficient to rescue the stabilization of basal dendritic LTP. Finally, otherwise stable LTP in ampakine-treated middle-aged rats can be eliminated by infusion of the extracellular BDNF scavenger TrkB-Fc. Together these results indicate that increases in endogenous BDNF signaling can offset deficits in the postinduction processes that stabilize LTP.

2017-10-01

Although workplace health promotion (WHP) has evolved over the last 40 years, systematically collected knowledge on factors influencing the functioning of WHP is scarce. Therefore, a qualitative systematic literature review was carried out to systematically identify and synthesize factors influencing the phases of WHP interventions: needs assessment, planning, implementation and evaluation. Research evidence was identified by searching electronic databases (Scopus, PubMed, Social Sciences Citation Index, ASSIA, ERIC, IBBS and PsycINFO) from 1998 to 2013, as well as by cross-checking reference lists of included peer-reviewed articles. The inclusion criteria were: original empirical research, description of WHP, description of barriers to and/or facilitators of the planning, implementation and/or evaluation of WHP. Finally, 54 full texts were included. From these, influencing factors were extracted and summarized using thematic analysis. The majority of influencing factors referred to the implementation phase, few dealt with planning and/or evaluation and none with needs assessment. The influencing factors were condensed into topics with respect to factors at contextual level (e.g. economic crisis); factors at organizational level (e.g. management support); factors at intervention level (e.g. quality of intervention concept); factors at implementer level (e.g. resources); factors at participant level (e.g. commitment to intervention) and factors referring to methodological and data aspects (e.g. data-collection issues). Factors regarding contextual issues and organizational aspects were identified across three phases. Therefore, future research and practice should consider not only the influencing factors at different levels, but also at different phases of WHP interventions. © The Author 2016.

The purpose of this study was to examine the prevalence of smoking in a nationally representative sample of Chinese elementary and middle school students and to investigate its risk factors from families and schools. The data were from the National Children's Study of China (NCSC), in which 24,013 fourth- to ninth-grade students were recruited from 100 counties in 31 provinces in China. Chi-square tests and one-way ANOVAs were used to analyze the relationships between smoking and the risk factors. Logistic regressions were used to calculate odds ratios. The prevalence of ever smokers and current smokers were 19.0% and 5.4%. Focusing on current smokers, boys, middle school students, rural students, boarding students, non-only children and those owning parents with low educational levels reported smoking significantly more than girls, elementary school students, urban students, non-boarding students, only children and those owning parents with high educational levels. Lower trust and support from teachers and higher parent-child conflict positively predicted both smoking and smoking frequency. Lower trust and support from classmates was associated with higher possibility of smoking. However, higher trust and support from classmates was associated with higher smoking frequency. Teacher smoking and friend smoking were only predictive of smoking, but not of smoking frequency. Boys, middle school students, rural students, boarding students, non-only children and those owning parents with low educational levels need special attention. The most risk factors for smoking and smoking frequency were lower trust and support from teachers and higher parent-child conflict. Copyright © 2014 Elsevier Ltd. All rights reserved.

Healthy middle-aged postmenopausal women have higher endothelium-dependent dilation and lower vasoconstrictor activity of endothelin-1 than men. Whether these sex-specific differences extend to patients with cardiovascular risk factors has not been investigated. The current study aimed to determine whether, in patients with cardiovascular risk factors, sex-specific differences exist in endothelium-dependent dilation and endothelin-1 activity. Forearm blood flow responses were measured by strain-gauge plethysmography during the intra-arterial infusion of acetylcholine, sodium nitroprusside, and the selective endothelin type A receptor blocker BQ-123 in 50 women and 64 men with cardiovascular risk factors. Acetylcholine and sodium nitroprusside induced a significant vasodilation in women and men alike (p < 0.01 for both). Also BQ-123 caused a significant vasodilation (p < 0.001) in both groups. The vasodilator response to acetylcholine was greater in women compared to men; however there were no differences in the response to sodium nitroprusside and BQ-123 (p = NS for both) between the two sex groups. Middle-aged women with cardiovascular risk factors have significantly higher endothelium-dependent dilation than middle-aged men; however, vascular endothelin 1 activity is similar in the two groups. These findings suggest that the presence of cardiovascular risk factors is associated with sex-specific effects on endothelium-dependent dilation but not on endothelin 1 activity. Further study is needed to confirm our findings and to characterize the mechanisms underlying this sex-specific regulation of endothelial function.

Hospital care mostly involves complex processes that are continuously adjusted to match individual client needs. As most patients cannot evaluate the technology used, they focus on personal interactions with care providers when making judgements about the care received. Nurses are the care team members that primarily provide ongoing care. This study aims to further understand factors that influence the way nursing staff relate to their patients. A model is presented of the contextual and self-perceptual factors that influence the level of customer/client orientation of nursing services in an Australian hospital setting along with details of a quantitative study. Nurses completed an anonymous questionnaire, which was then mailed directly to the researchers. Analysis of the data included factor analysis, regression and path analysis. The results show that contextual elements such as management commitment to service quality and self-perceptual factors such as role stress impact on the nurses' client service orientation. However, the variables being studied commonly have both direct and indirect effects with feelings about commitment to the organization having a notable mediating influence. The scales adapted from use in other industries are able to measure the perceptual and outcome variables in a health institutional setting. The managerial implications are that both a comprehensive programme of organizational culture and individual staff member development is needed if an enhanced customer orientation and the consequent improvement in client satisfaction with nursing care is to occur.

Traditional bone setting is a practice that is common in our environment. This is a community based survey of opinions concerning orthodox and traditional fracture management in four states of the middle belt of Nigeria. We set out to ascertain the factors influencing preference of treatment of fractures among populations in the middle belt of Nigeria. A community based questionnaire survey of randomly selected adults regarding preference of choice of treatment between orthodox and traditional fracture management. One hundred and eighty-six questionnaires were found analyzable with a male to female ratio of 2:1. There was a preponderance of preference for orthodox fracture management (70.4%). Decisions were mainly collegiate, outside the influence of the individual; only 9.9% decided to attend traditional bone setters on their own. Reasons adduced for preference of traditional bone setters were incongruous and inconsistent. A fixated cultural outlook was recognized as being the motivating factor for patronage of traditional bone setters. Need for enlightenment campaign of the public against patronage of traditional bone setters is emphasized. A gradual phasing out of traditional bone setting with a road map towards making orthodox fracture management available to all is advocated.

Subjective memory complaints, vascular risk factors and psychological distress in the middle-aged: a cross-sectional study

PubMed Central

2011-01-01

Background Subjective memory complaints (SMC) are common but their significance is still unclear. It has been suggested they are a precursor of mild cognitive impairment (MCI) or dementia and an early indicator of cognitive decline. Vascular risk factors have an important role in the development of dementia and possibly MCI. We therefore aimed to test the hypothesis that vascular risk factors were associated with SMC, independent of psychological distress, in a middle-aged community-dwelling population. Methods A cross-sectional analysis of baseline data from the 45 and Up Study was performed. This is a cohort study of people living in New South Wales (Australia), and we explored the sample of 45, 532 participants aged between 45 and 64 years. SMC were defined as 'fair' or 'poor' on a self-reported five-point Likert scale of memory function. Vascular risk factors of obesity, diabetes, hypertension, hypercholesterolemia and smoking were identified by self-report. Psychological distress was measured by the Kessler Psychological Distress Scale. We tested the model generated from a randomly selected exploratory sample (n = 22, 766) with a confirmatory sample of equal size. Results 5, 479/45, 532 (12%) of respondents reported SMC. Using multivariate logistic regression, only two vascular risk factors: smoking (OR 1.18; 95% CI = 1.03 - 1.35) and hypercholesterolaemia (OR 1.19; 95% CI = 1.04 - 1.36) showed a small independent association with SMC. In contrast psychological distress was strongly associated with SMC. Those with the highest levels of psychological distress were 7.00 (95% CI = 5.41 - 9.07) times more likely to have SMC than the non-distressed. The confirmatory sample also demonstrated the strong association of SMC with psychological distress rather than vascular risk factors. Conclusions In a large sample of middle-aged people without any history of major affective illness or stroke, psychological distress was strongly, and vascular risk factors only weakly

Social Consequences of Academic Teaming in Middle School: The Influence of Shared Course-Taking on Peer Victimization

Echols, Leslie

2014-01-01

This study examined the influence of academic teaming (i.e., sharing academic classes with the same classmates) on the relationship between social preference and peer victimization among 6th grade students in middle school. Approximately 1,000 participants were drawn from 5 middle schools that varied in their practice of academic teaming. A novel methodology for measuring academic teaming at the individual level was employed, in which students received their own teaming score based on the unique set of classmates with whom they shared academic courses in their class schedule. Using both peer- and self-reports of victimization, the results of two path models indicated that students with low social preference in highly teamed classroom environments were more victimized than low preference students who experienced less teaming throughout the school day. This effect was exaggerated in higher performing classrooms. Implications for the practice of academic teaming were discussed. PMID:25937668

The aim of this study was to identify factors that influence career choice in UK medical students. Students at seven institutions were invited to rate how important various factors were on influencing their career choices and how interested they were in pursuing different specialties. The influence of interpersonal relationship networks on career choice was also evaluated. 641 responses were collected. 44% (283) were male, 16% (105) were graduates and 41% (263) were final-year students. For Dermatology (p = 0.009), Paediatrics (p = 0.000), Radiology (p = 0.000), Emergency Medicine (p = 0.018) and Cardiothoracic Surgery (p = 0.000), there was a clear correlation between completing a clinical attachment and an interest in pursuing the specialty. Perceived characteristics of the speciality, individually and in clusters were considered important by specific subgroups of students, such as those interested in surgery. These students considered prestige (p = 0.0003), role models (p = 0.014), financial rewards after training (p = 0.0196) and technical challenge (p = 0.0011) as important factors. Demographics such as sex and age played a significant role in career choice. Interpersonal relationship networks do not have a significant influence on career intentions. This study shows that the career intentions of British medical students are influenced by their undergraduate experience and by the weight they place on different specialty-related factors.

The influence of sea level and cyclones on Holocene reef flat development: Middle Island, central Great Barrier Reef

The geomorphology and chronostratigraphy of the reef flat (including microatoll ages and elevations) were investigated to better understand the long-term development of the reef at Middle Island, inshore central Great Barrier Reef. Eleven cores across the fringing reef captured reef initiation, framework accretion and matrix sediments, allowing a comprehensive appreciation of reef development. Precise uranium-thorium ages obtained from coral skeletons revealed that the reef initiated ~7873 ± 17 years before present (yBP), and most of the reef was emplaced in the following 1000 yr. Average rates of vertical reef accretion ranged between 3.5 and 7.6 mm yr-1. Reef framework was dominated by branching corals ( Acropora and Montipora). An age hiatus of ~5000 yr between 6439 ± 19 and 1617 ± 10 yBP was observed in the core data and attributed to stripping of the reef structure by intense cyclones during the mid- to late-Holocene. Large shingle ridges deposited onshore and basset edges preserved on the reef flat document the influence of cyclones at Middle Island and represent potential sinks for much of the stripped material. Stripping of the upper reef structure around the outer margin of the reef flat by cyclones created accommodation space for a thin (<1.2 m) veneer of reef growth after 1617 ± 10 yBP that grew over the eroded mid-Holocene reef structure. Although limited fetch and open-water exposure might suggest the reef flat at Middle Island is quite protected, our results show that high-energy waves presumably generated by cyclones have significantly influenced both Holocene reef growth and contemporary reef flat geomorphology.

A national study found that infants born in low socioeconomic areas had the worst infant mortality rates (IMRs) and the highest racial disparity. Racial disparities in birth outcomes are also evident in the city of Milwaukee, with African American infants at 3 times greater the risk than white infants. This study was conducted to examine the influence of socioeconomic status (SES) and race on birth outcomes in the city of Milwaukee. Milwaukee ZIP codes were stratified into lower, middle, and upper SES groups. IMR, low birth weight, and preterm birth rates by race were analyzed by SES group for the years 2003 to 2007. The overall IMR for the lower, middle, and upper SES groups were 12.4, 10.7, and 7.7, respectively. The largest racial disparity in IMR (3.1) was in the middle SES group, versus lower (1.6) and upper (1.8) SES groups. The overall percent of low birth weight infants for the lower, middle, and upper SES groups was 10.9%, 9.5%, and 7.5%, respectively. Racial disparity ratios in low birth weight were 2.0, 1.9, and 1.9 for lower, middle and upper SES groups. The overall percent of preterm birth was 15.4%, 13.2%, and 10.6% of births within the lower, middle, and upper SES groups, respectively, with a disparity ratio of 1.6 across all SES groups. For all outcomes, African American infants born in the upper SES group fared the same or worse than white infants born in the lower SES group. Although higher SES appeared to have a protective effect for whites in Milwaukee, it did not have the same protective effect for African Americans.

Environmental influences: factors influencing a woman's decision to use dietary supplements.

Conner, Mark; Kirk, Sara F L; Cade, Janet E; Barrett, Jennifer H

2003-06-01

Use of dietary supplements by women, particularly those over 40 years of age may be widespread in the United Kingdom. However, from surveillance data, there appears to be a disparity between nutrition and health needs and the rationale for and actual use of dietary supplements by women. This apparent paradox forms the basis for an inverse supplement hypothesis (i.e., supplement use in women appears to be most prevalent among those with least need). Little research has been done to examine the factors underlying the decision to use dietary supplements. Reasons for consuming dietary supplements are often complex, combining social, psychological, knowledge and economic factors. The theory of planned behavior is a widely used model for assessing factors influencing behavioral motivation and action that may be useful for assessing specific diet- and nutrition-related practices. It provided the basis for the development of a questionnaire to explore overall dietary supplement use in a cohort of women in the United Kingdom. The analysis of factors related to beliefs underlying dietary supplement use revealed differences between supplement users and nonusers. Differences included a stronger belief by users than nonusers that taking dietary supplements ensures against possible ill health. Both users and nonusers of supplements also perceived the media (books and magazines) to be a powerful influence on a person's decision to use supplements. These findings highlight the potential of the theory of planned behavior in exploring supplement-taking behavior while throwing light on the factors influencing an individual's motivations to use dietary supplements.

Uncovering Factors Influencing Interpersonal Health Communication

Donné, Lennie; Jansen, Carel; Hoeks, John

Talking to friends, family, or peers about health issues might, among other things, increase knowledge of social norms and feelings of self-efficacy in adopting a healthier lifestyle. We often see interpersonal health communication as an important mediating factor in the effects of health campaigns on health behavior. No research has been done so far, however, on factors that influence whether and how people talk about health issues without being exposed to a health campaign first. In this exploratory study, we interviewed 12 participants about their communication behavior concerning six different health themes, like smoking and exercising. The results suggest that at least four types of interpersonal health communication can be distinguished, each influenced by different factors, like conversational partner and objective of the conversation. Future research should take this diversity of interpersonal health communication into account, and focus on designing health campaigns that aim to trigger dialogue within target populations.

Objectives Breast cancer incidence rates are rising in Qatar. Although the Qatari government provides subsidised healthcare and screening programmes that reduce cost barriers for residents, breast cancer screening (BCS) practices among women remain low. This study explores the influence of socioeconomic status on BCS among Arab women in Qatar. Setting A multicentre, cross-sectional quantitative survey was conducted with 1063 Arab women (87.5% response rate) in Qatar from March 2011 to July 2011. Women who were 35 years or older and had lived in Qatar for at least 10 years were recruited from seven primary healthcare centres and women's health clinics in urban and semiurban regions of Qatar. Associations between socioeconomic factors and BCS practice were estimated using χ2 tests and multivariate logistic regression analyses. Results Findings indicate that less than one-third of the participants practised BCS appropriately, whereas less than half of the participants were familiar with recent BCS guidelines. Married women and women with higher education and income levels were significantly more likely to be aware of and to practise BCS than women who had lower education and income levels. Conclusions Findings indicate low levels of awareness and low participation rates in BCS among Arab women in Qatar. Socioeconomic factors influence these women's participation in BCS activities. The strongest predictors for BCS practice are higher education and higher income levels. Recommendations Additional research is needed to explore the impact of economic factors on healthcare seeking behaviours in the Middle Eastern countries that have a high national gross domestic product where healthcare services are free or heavily subsidised by the government; promotion of BCS and intervention strategies in these countries should focus on raising awareness about breast cancer, the cost and benefit of early screening for this disease, particularly among low-income women.

The tympanic annulus is a fibrocartilage ligament that supports the tympanic membrane in a sulcus at the end of the outer ear canal. Among many FE models of the middle ear found in literature, the effect of different boundary conditions at tympanic annulus on middle ear mechanics was not found. In order to investigate the influence of different representations of this detail in FE models, three different ways to connect the tympanic annulus to the outer ear canal were modelled in a reduced middle ear system. This reduced system includes tympanic membrane, tympanic annulus, manubrium, malleus and anterior ligament of malleus. The numerical frequency response function Humbo (umbo velocity vs sound pressure at tympanic membrane) was analyzed through the different boundary conditions and compared to numerical and experimental data from the literature. Also a numerical modal analysis was performed to improve the analysis. It was found that the boundary conditions used to represent the connection between Tympanic Annulus and Outer Ear Canal can change the global stiffness of the system and its natural frequencies as well as change the modal shape of high order modes.

Understanding the characteristics of vessel traffic flow is crucial in maintaining navigation safety, efficiency, and overall waterway transportation management. Factors influencing vessel traffic flow possess diverse features such as hierarchy, uncertainty, nonlinearity, complexity, and interdependency. To reveal the impact mechanism of the factors influencing vessel traffic flow, a hierarchical model and a coupling model are proposed in this study based on the interpretative structural modeling method. The hierarchical model explains the hierarchies and relationships of the factors using a graph. The coupling model provides a quantitative method that explores interaction effects of factors using a coupling coefficient. The coupling coefficient is obtained by determining the quantitative indicators of the factors and their weights. Thereafter, the data obtained from Port of Tianjin is used to verify the proposed coupling model. The results show that the hierarchical model of the factors influencing vessel traffic flow can explain the level, structure, and interaction effect of the factors; the coupling model is efficient in analyzing factors influencing traffic volumes. The proposed method can be used for analyzing increases in vessel traffic flow in waterway transportation system.

This study aimed to identify and assess the factors that influence communication quality between clinical pharmacists and patients using a structural equation model based on the predisposing, reinforcing, and enabling constructs in educational/environmental diagnosis and evaluation-policy, regulatory, and organizational constructs in educational and ecological development model to identify the most effective path to increase their communication quality. A survey was conducted at 253 Class-A tertiary hospitals in China from March to December 2016. During on-site observations, verbal communications between clinical pharmacists ( n = 752) and patients were audio recorded, and communication quality was rated by an expert panel on an 8-item Quality of Communication Rating Scale. Clinical pharmacists completed questionnaires that examined the predisposing, enabling, and reinforcing factors that influenced communication quality. Finally, AMOS was employed to examine the relationships between the three factors and communication quality. The results indicated that all three factors positively affected communication quality, with correlation coefficients of .26, .13, and .17, respectively. The most influential predisposing factor was attitude (.77), the most influential enabling factors were self-efficacy (.71) and confidence (.72), and the most influential reinforcing factor was rewards (.74). The findings suggest that pharmacists' attitudes toward, perceived knowledge of, and skill and confidence in communication, and the rewards offered by pharmacy management are the most influential factors that influence communication quality.

Increasing children's active travel to school may be 1 strategy for addressing the growing prevalence of obesity among school age children. Using the School Travel Survey, we examined South Carolina school district leaders' perceptions of factors that influence elementary and middle school students walking to school. Frequency distributions and chi-square tests were used to analyze the survey responses; open-ended questions were reviewed qualitatively for recurring topics and themes. School and district leaders (N = 314) most often reported street crossing safety (54.0%) and number of sidewalks (54.0%) as priority factors that should be addressed to increase students' active travel to school, followed by distance to school (46.0%), traffic volume (42.4%), parental attitudes (27.0%), traffic speed (26.7%), neighborhood condition (24.4%), and student attitudes (10.0%). Several respondents expressed concerns about liability issues related to students' active travel to school while others reported that schools are not responsible for students' safety once students leave school grounds. Independent of their comments about liability, respondents were concerned about the safety of students while walking to school. Those promoting active travel to school may benefit from addressing those factors perceived as most important by school and district leaders, including street crossing safety, number of sidewalks, and by educating school and district leaders about liability and safety issues related to students walking to school. © 2011, American School Health Association.

To explore the influencing factors from staff nurses, nurse managers, nursing directors and a physician involved in nursing evidence implementation in Mainland China. Although the need for evidence-based nursing is well recognised, continuous efforts are needed to strive for closing the gap from evidence to action. Previous studies have explored influencing factors from individual and organisational perspectives in Western countries. However, it remains unclear what the influences (i.e., context and culture) in the developing countries as China. A grounded theory design using in-depth individual interviews was conducted. Interviews with 56 participants from 24 evidence-based nursing implementation projects were conducted in Mainland China. Constant comparative analysis was used to discover the concepts describing the influencing factors during the implementation process. Factors that influenced implementation of evidence-based practice in the Chinese context were identified. These included the leaders of the projects, the nature of the evidence, practising nurses, patients involved in the projects, the system where the projects were implemented, as well as the influence from outside of the system. A variety of factors influencing evidence implementation in Chinese nursing context were identified and further explored from the perspective of different project leaders and culture influence. There is apparently a strong demand for a supportive system, targeted strategies to facilitate various evidence implementations and integrated core elements of evidence-based practice at the point care. The blurred boundaries and complexity of influencing factors call for a systematic and dynamic perspective during implementation. The competitive priorities emphasise the importance of integration between clinical nursing care and evidence-based practice. © 2017 John Wiley & Sons Ltd.

This study examined the relationship between family context of middle school students on their educational and occupational ideals. Middle school students (N = 2000) responded to questions assessing family location, family structure, parental educational level and family economic status, as well as to the Middle School Students' Ideals Questionnaire. Multivariate analysis of variance indicated that life, educational and occupational ideals of female students and students in lower grades were higher than that of male students and students in higher grades. Regression analysis indicated that paternal education level have a positive association with educational and occupational ideals, but not life ideals, and family economic status have a positive relation to life ideals, but not educational and occupational ideals. Moreover, the interaction between family economic status and family location has a negative association with students' life, educational and occupational ideals. These results suggest that different factors predicted different ideals of adolescents, and that family economic status had a negative moderating effect on the relationship between family location and ideals of students. © 2015 International Union of Psychological Science.

This study was conducted to identify the factors that influence nurses' organizational citizenship behavior. A cross-sectional design was used, with a convenience sample of 547 nurses from four university hospitals in Seoul and Gyeonggi province. The data were collected through a questionnaire survey done from September 22 to October 10, 2008. The tools used for this study were scales on organizational citizenship behavior (14 items), self-leadership (14 items), empowerment (10 items), organizational commitment (7 items), job satisfaction (8 items) and transformational.transactional leadership (14 items). Cronbach's alpha and factor analysis were examined to test reliability and construct validity of the scale. The data collected were processed using SPSS Window 15.0 Program for actual numbers and percentages, differences in the dependent variable according to general characteristics, and means, standard deviations, correlation coefficients and multiple regression analysis. The factors influencing nurses' organizational citizenship behavior were identified as self-leadership(beta=.247), empowerment (beta=.233), job satisfaction (beta=.209), organizational commitment (beta=.158), and transactional leadership (beta=.142). Five factors explained 42.0% of nurses' organizational citizenship behavior. The results of this study can be used to develop further management strategies for enhancement of nurses' organizational citizenship behavior.

The aim of this study was to compare health-related quality of life (HRQOL) by menopausal stage and investigate its associated factors in middle-aged Chinese women. This was a cross-sectional, community-based study involving 868 participants aged 40-60 years in Gongshu District, Hangzhou, Zhejiang, PR China. HRQOL was assessed by the Short-Form Health Survey (SF-36). The menopausal symptoms and sociodemographic characteristics were surveyed. The median (25-75th percentile) age of all participants was 51.24 (46.37-55.55) years. Differences were seen in domains of physical functioning, role-physical, bodily pain, general health and health transition by menopausal stage. The multivariate logistic regressions showed that there were associations between menopausal stage and HRQOL. Compared to premenopausal women, perimenopausal women had increased risks of having impaired functions in role-physical and health transition, and postmenopausal women were more likely to have impaired functions in physical functioning and health transition (p < 0.05 for all). Menopausal symptoms were negatively associated with HRQOL. Being married or co-habiting tended to relate to better general health. Being unemployed or retired tended to be associated with impaired role-physical. There was a difference in HRQOL by menopausal stage in middle-aged Chinese women. Menopause might exert a negative impact on HRQOL, adjusting for menopausal symptoms and sociodemographic factors.

The aim of this study is to quantitatively analyze the influence of risk factors on the blood glucose level, and to provide theory basis for understanding the characteristics of blood glucose change and confirming the intervention index for type 2 diabetes. The quantitative method is proposed to analyze the influence of risk factors on blood glucose using back propagation (BP) neural network. Ten risk factors are screened first. Then the cohort is divided into nine groups by gender and age. According to the minimum error principle, nine BP models are trained respectively. The quantitative values of the influence of different risk factors on the blood glucose change can be obtained by sensitivity calculation. The experiment results indicate that weight is the leading cause of blood glucose change (0.2449). The second factors are cholesterol, age and triglyceride. The total ratio of these four factors reaches to 77% of the nine screened risk factors. And the sensitivity sequences can provide judgment method for individual intervention. This method can be applied to risk factors quantitative analysis of other diseases and potentially used for clinical practitioners to identify high risk populations for type 2 diabetes as well as other disease.

Personal and interpersonal correlates of bullying behaviors among Korean middle school students.

2010-01-01

This study simultaneously investigates personal and interpersonal traits that were found to be important factors of bullying behavior using data collected from 1,238 randomly selected Korean middle school students. Using a modified and expanded definition of bullying based on a more culturally sensitive approach to bullying, this study categorizes bullies into three groups: Type I (minor-covert-nonchronic bullying), Type II (moderate-covert-chronic or severe-overt-nonchronic bullying), and Type III (severe-overt-chronic bullying). In addition, this study empirically tests several factors for the first time. Those factors are fun-seeking tendency, teachers' attitude toward bullying, teachers' effectiveness of intervention, teachers' moral authority, power dynamic, and pseudofriendship. The comparison across three groups provided unique findings that different factors were differently related to different groups of bullies. Specifically, teachers have influence on bullying only for the moderate group (Type II), and parents have influence on bullying only for the minor group (Type I). The most important and constant factors across all different groups were prior bullying victimization experience and fun-seeking tendency.

Factors influencing healthcare service quality

Background: The main purpose of this study was to identify factors that influence healthcare quality in the Iranian context. Methods: Exploratory in-depth individual and focus group interviews were conducted with 222 healthcare stakeholders including healthcare providers, managers, policy-makers, and payers to identify factors affecting the quality of healthcare services provided in Iranian healthcare organisations. Results: Quality in healthcare is a production of cooperation between the patient and the healthcare provider in a supportive environment. Personal factors of the provider and the patient, and factors pertaining to the healthcare organisation, healthcare system, and the broader environment affect healthcare service quality. Healthcare quality can be improved by supportive visionary leadership, proper planning, education and training, availability of resources, effective management of resources, employees and processes, and collaboration and cooperation among providers. Conclusion: This article contributes to healthcare theory and practice by developing a conceptual framework that provides policy-makers and managers a practical understanding of factors that affect healthcare service quality.

In this study we show that bonobos and capuchin monkeys can learn to search in the middle of a landmark configuration in a small-scale space. Five bonobos (Pan paniscus) and 2 capuchin monkeys (Cebus apella) were tested in a series of experiments with the expansion test paradigm. The primates were trained to search in the middle of a 4- or 2-landmark configuration, and were then tested with the same configuration expanded. Neither species searched in the middle of the expanded 4-landmark configuration. When presented with a 2-landmark configuration and a constant or variable inter-landmark training distance, the subjects sometimes searched preferentially in the middle of the expanded configuration. We discuss 2 alternative explanations of the results: extracting a middle rule or averaging between different goal-landmark vectors. In any case, compared to adult humans, primates appear highly constrained in their abilities to search in the middle of a configuration of detached landmarks. We discuss some of the factors that may influence the primates' behavior in this task.

A prospective examination of the path from child abuse and neglect to illicit drug use in middle adulthood: the potential mediating role of four risk factors.

This study examines prostitution, homelessness, delinquency and crime, and school problems as potential mediators of the relationship between childhood abuse and neglect (CAN) and illicit drug use in middle adulthood. Children with documented cases of physical and sexual abuse and neglect (ages 0-11) during 1967-1971 were matched with non-maltreated children and followed into middle adulthood (approximate age 39). Mediators were assessed in young adulthood (approximate age 29) through in-person interviews between 1989 and 1995 and official arrest records through 1994 (N = 1,196). Drug use was assessed via self-reports of past year use of marijuana, psychedelics, cocaine, and/or heroin during 2000-2002 (N = 896). Latent variable structural equation modeling (SEM) was used to test: (1) a four-factor model with separate pathways from CAN to illicit drug use through each of the mediating risk factors and (2) a second-order model with a single mediating risk factor comprised of prostitution, homelessness, delinquency and crime, and poor school performance. Analyses were performed separately for women and men, controlling for race/ethnicity and early drug use. In the four-factor model for both men and women, CAN was significantly related to each of the mediators, but no paths from the mediators to drug use were significant. For women, the second-order risk factor mediated the relationship between CAN and illicit drug use in middle adulthood. For men, neither child abuse and neglect nor the second-order risk factor predicted drug use in middle adulthood. These results suggest that for women, the path from CAN to middle adulthood drug use is part of a general "problem behavior syndrome" evident earlier in life.

Factors influencing US medical students' decision to pursue surgery.

Interest and applications to surgery have steadily decreased over recent years in the United States. The goal of this review is to collect the current literature regarding US medical students' experience in surgery and factors influencing their intention to pursue surgery as a career. We hypothesize that multiple factors influence US medical students' career choice in surgery. Six electronic databases (PubMed, SCOPUS, Web of Science, Education Resources Information Center, Embase, and PsycINFO) were searched. The inclusion criteria were studies published after the new century related to factors influencing surgical career choice among US medical students. Factors influencing US medical student surgical career decision-making were recorded. A quality index score was given to each article selected to minimize risk of bias. We identified 38 relevant articles of more than 1000 nonduplicated titles. The factors influencing medical student decision for a surgical career were categorized into five domains: mentorship and role model (n = 12), experience (clerkship n = 9, stereotype n = 4), timing of exposure (n = 9), personal (lifestyle n = 8, gender n = 6, finance n = 3), and others (n = 2). This comprehensive systemic review identifies mentorship, experience in surgery, stereotypes, timing of exposure, and personal factors to be major determinants in medical students' decisions to pursue surgery. These represent areas that can be improved to attract applicants to general surgery residencies. Surgical faculty and residents can have a positive influence on medical students' decisions to pursue surgery as a career. Early introduction to the field of surgery, as well as recruitment strategies during the preclinical and clinical years of medical school can increase students' interest in a surgical career.

Sexual dysfunction is a serious public health problem that affects women's quality of life. However, there is very little epidemiological data on its incidence in Hong Kong Chinese women. To estimate the prevalence of, and risk factors associated with sexual dysfunction among young and middle-aged women in Hong Kong. The study was part of the ninth Knowledge, Attitude, and Practice survey conducted by the Family Planning Association of Hong Kong in 2007. The dataset comprised 1,510 face-to-face interviews with Hong Kong Chinese women aged 19-49 living in the community. The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition classification of sexual dysfunction was used to measure female sexual dysfunction (FSD). At least one form of FSD was reported by 37.9% of the sample. Multivariate analysis showed that having sought medical help for sexual problems (odds ratio [OR] = 4.20), having a partner with erectile dysfunction (OR = 2.44) and premature ejaculation (OR = 2.56), perceiving sex as unimportant to marriage (OR = 1.57), and reporting marital dissatisfaction (OR = 1.45) were all significant risk factors for FSD and its specific components among the sample. However, having liberal attitudes to sex (OR = 0.63) was a protective factor. The prevalence of FSD is lower among Hong Kong Chinese young and middle-aged women than in the United States and some Asian countries. Factors contributing to the risk of FSD span the domains of sexual experience, attitudes to sex, and relationship factors. These findings suggest future directions for the delivery of services addressing the prevention and treatment of FSD. © 2012 International Society for Sexual Medicine.

Factors that influence the childbearing intentions of Canadian men.

The role of men in the childbearing decision process and the factors that influence men's childbearing intentions have been relatively unexplored in the literature. This study aimed to describe the factors that strongly influence the childbearing intentions of men and to describe differences in these factors according to men's age group. A telephone survey (response rate 84%) was conducted with 495 men between the ages of 20 and 45 living in an urban setting who, at the time of contact, did not have biological children. Men were asked about what factors strongly influence their intention to have children. Univariable and multivariable logistic regressions were conducted to determine if these factors were significantly associated with age. Of those sampled, 86% of men reported that at some point in the future they planned to become a parent. The factors that men considered to be most influential in their childbearing intentions were: the need to be financially secure, their partner's interest/desire to have children, their partner's suitability to be a parent and their personal interest/desire to have children. Men who were 35-45 years old had lower odds of stating that financial security (crude OR: 0.32, 95% CI: 0.18-0.54) and partner's interest in having children (crude OR: 0.57, 95% CI: 0.33-0.99) were very influential, but had higher odds of stating that their biological clock (crude OR: 4.37, 95% CI: 1.78-10.76) was very influential in their childbearing intentions than men in the 20-24 year age group. The factors that influence men's intentions about when to become a parent may change with age. Understanding what influences men to have children, and what they understand about reproductive health is important for education, program and policy development.

Changes in reference evapotranspiration and its driving factors in the middle reaches of Yellow River Basin, China.

2017-12-31

Reference evapotranspiration (ET 0 ) is important for agricultural, environmental and other studies, and understanding the attribution of its change is helpful to provide information for irrigation scheduling and water resources management. The present study investigates the attribution of the change of ET 0 at 49 meteorological stations in the middle reaches of Yellow River basin (MRYRB) of China from 1960 to 2012. Results show that annual ET 0 increases from the northwest to the southeast of MRYRB in space. We find that annual ET 0 clearly presents a zigzag change pattern rather than a monotonically change during the whole period. The detected three breakpoints at 1972, 1988 and 1997 divide the whole period into four subperiods. The sensitivity analysis indicates that the ET 0 is the most sensitive to surface solar radiation (Rs), followed by relative humidity (RH) and mean air temperature (T), and the least sensitive to wind speed (u) in our study area. Furthermore, we find that ET 0 is becoming less sensitive to RH and more sensitive to T during 1960-2012. The attributions of the change in ET 0 vary largely at different regions and subperiods. The declined wind speed is the dominant factor, followed by Rs to the ET 0 reduction during 1960-2012. Further analysis shows that Rs and u are the two major contributing factors that control the change of ET 0 at most stations and during most subperiods. Our study confirms that the change of ET 0 is influenced by the complex interactions of climatic factors, and the dominant factor to the change of ET 0 is different in various regions and time periods. The results presented here can provide a reference for agricultural production and water resources management in MRYRB as well as other semi-arid and semi-humid regions.

The association between level of education and disability pension (DP) is well known. Earlier studies have investigated the importance of early life factors and work characteristics but not in combination. The aim of this study was to investigate the association between level of education and DP among Swedish middle-aged working men and to what extent such an association can be explained by factors measured in late adolescence and work characteristics in adulthood. Information about IQ, health-related lifestyle factors, psychiatric and musculoskeletal diagnoses was obtained from the 1969 conscription cohort, consisting of 49,321 Swedish men. Data collected when subjects were 18-20 years of age were combined with national register-based information about level of education, job control and physical strain at work in adulthood, and information about DP between 1991 and 2002. There was a strong graded association between level of education and DP. Those with the lowest level of education had a four times greater probability of having DP as compared with those with the highest level. In multivariable analyses, factors measured in late adolescence, IQ in particular, attenuated the association more than work-related characteristics in adulthood. The authors found an association between level of education and DP among Swedish middle-aged working men. A large part of the association was explained by factors measured in late adolescence, IQ in particular, and somewhat less by work characteristics measured in adulthood. Level of education remained as a significant predictor of DP in middle age after full adjustment.

Interaction Between Allergy and Middle Ear Infection.

PubMed

Oh, Jeong-Hoon; Kim, Woo Jin

2016-09-01

Recent studies have attempted to identify interactions among the causes of otitis media with effusion (OME). This review discusses the interaction between allergy and infection with regard to host and environmental factors in terms of the development of OME. Protection of the upper airway against microbial invasion requires active interaction between the defense mechanisms of the respiratory epithelium, including innate and adaptive immunity, and mechanical factors. The impairment of these defenses due to allergy and/or increased bacterial resistance may lead to increased susceptibility to infectious organisms in the respiratory tract and middle ear mucosa. Recent genetic studies have provided valuable information about the association of Toll-like receptor signaling variations with clinical phenotypes and the risk of infection in the middle ear. Among the causal factors of OME, allergy not only induces an inflammatory reaction in the middle ear cavity but also facilitates the invasion of infectious pathogens. There is also evidence that allergy can affect the susceptibility of patients to infection of the upper respiratory tract, including the middle ear cavity.

Early life factors, childhood cognition and postal questionnaire response rate in middle age: the Aberdeen Children of the 1950s study.

Little is known about the relationship between early life factors and survey response in epidemiological studies of adults. The Children of the 1950s cohort is composed of 12,150 children (boys 51.7%) born in Aberdeen 1950-56 and in primary schools in the city in 1962. Information on birth weight, gestational age, growth, behaviour and socio-economic position at birth and in childhood were obtained from contemporaneous records. Cognitive test scores at ages 7,9 and 11 years were also available from school records. The outcome was response to a postal questionnaire sent (2001-2003) to surviving cohort members in middle age. Of 11,282 potentially mailed subjects, 7,183 (63.7%) returned questionnaires. Response rates were highest among females, and those whose parents were married at birth, were in a non-manual social class at birth or in childhood, had fewer siblings, were taller and heavier in childhood for their age and had lower Rutter B behavioural scores. Childhood cognitive test scores at every age were strongly and positively related to the response rate to a postal questionnaire independently of other early life factors monotonically across the entire range of test scores. Those in the bottom fifth at age 11 had a response rate of 49% while those in the top fifth 75%. The strength and consistency of the association of childhood cognition with questionnaire response rate in middle age is surprisingly large. It suggests that childhood cognition across the entire normal range is a powerful influence on the complex set of later behaviours that comprise questionnaire response. The extent of possible response bias in epidemiological studies of the associations between childhood characteristics (particularly those related to cognition) and later health is probably larger than is generally realised, at least in situations where the survey instrument is a postal questionnaire.

The Global Code of Practice on the International Recruitment of Health Personnel focuses particularly on migration of doctors from low- and middle-income countries. Less is understood about migration from high-income countries. Recession has impacted several European countries in recent years, and in some cases emigration has reached unprecedented levels. This study measures and explores the predictors of trainee doctor emigration from Ireland. Using a partially mixed sequential dominant (quantitative) study design, a nationally representative sample of 893 trainee doctors was invited to complete an online survey. Of the 523 who responded (58.6% response rate), 423 were still in Ireland and responded to questions on factors influencing intention to practice medicine abroad and are the subjects of this study. Explanatory factors for intention to practice medicine in Ireland in the foreseeable future, the primary outcome, included demographic variables and experiences of working within the Irish health system. Associations were examined using univariable and multivariable logistic regression to estimate odds ratios for factors influencing the primary outcome. Qualitative interviews were conducted with 50 trainee doctors and analysed thematically, exploring issues associated with intention to practice medicine abroad. There were high levels of dissatisfaction among trainee doctors around working conditions, training and career progression opportunities in Ireland. However, most factors did not discriminate between intention to leave or stay. Factors that did predict intention to leave included dissatisfaction with one's work-life balance (odds ratio (OR) 2.51; 95% confidence interval (CI) 1.53-4.10; P < 0.001); feeling that the quality of training in Ireland was poor (OR 1.82; 95% CI 1.09-3.05; P = 0.002) and leaving for family or personal reasons (OR 1.85; 95% CI 1.08-3.17; P = 0.027). Qualitative findings illustrated the stress of doing postgraduate

To study the number of health information systems (HISs), applicable to administrative, clinical, and executive decision support functionalities, adopted by acute care hospitals and to examine how hospital market, organizational, and financial factors influence HIS adoption. A cross-sectional analysis was performed with 1441 hospitals selected from metropolitan statistical areas in the United States. Multiple data sources were merged. Six hypotheses were empirically tested by multiple regression analysis. HIS adoption was influenced by the hospital market, organizational, and financial factors. Larger, system-affiliated, and for-profit hospitals with more preferred provider organization contracts are more likely to adopt managerial information systems than their counterparts. Operating revenue is positively associated with HIS adoption. The study concludes that hospital organizational and financial factors influence on hospitals' strategic adoption of clinical, administrative, and managerial information systems.

Maturity models facilitate organizational management, including information systems management, with hospital organizations no exception. This article puts forth a study carried out with a group of experts in the field of hospital information systems management with a view to identifying the main influencing factors to be included in an encompassing maturity model for hospital information systems management. This study is based on the results of a literature review, which identified maturity models in the health field and relevant influencing factors. The development of this model is justified to the extent that the available maturity models for the hospital information systems management field reveal multiple limitations, including lack of detail, absence of tools to determine their maturity and lack of characterization for stages of maturity structured by different influencing factors.

A Review of Factors Influencing Athletes' Food Choices.

PubMed

Birkenhead, Karen L; Slater, Gary

2015-11-01

Athletes make food choices on a daily basis that can affect both health and performance. A well planned nutrition strategy that includes the careful timing and selection of appropriate foods and fluids helps to maximize training adaptations and, thus, should be an integral part of the athlete's training programme. Factors that motivate food selection include taste, convenience, nutrition knowledge and beliefs. Food choice is also influenced by physiological, social, psychological and economic factors and varies both within and between individuals and populations. This review highlights the multidimensional nature of food choice and the depth of previous research investigating eating behaviours. Despite numerous studies with general populations, little exploration has been carried out with athletes, yet the energy demands of sport typically require individuals to make more frequent and/or appropriate food choices. While factors that are important to general populations also apply to athletes, it seems likely, given the competitive demands of sport, that performance would be an important factor influencing food choice. It is unclear if athletes place the same degree of importance on these factors or how food choice is influenced by involvement in sport. There is a clear need for further research exploring the food choice motives of athletes, preferably in conjunction with research investigating dietary intake to establish if intent translates into practice.

Microbiology and risk factors associated with war-related wound infections in the Middle East.

PubMed

Sahli, Z T; Bizri, A R; Abu-Sittah, G S

2016-10-01

The Middle East region is plagued with repeated armed conflicts that affect both civilians and soldiers. Injuries sustained during war are common and frequently associated with multiple life-threatening complications. Wound infections are major consequences of these war injuries. The microbiology of war-related wound infections is variable with predominance of Gram-negative bacteria in later stages. The emergence of antimicrobial resistance among isolates affecting war-related wound injuries is a serious problem with major regional and global implications. Factors responsible for the increase in multidrug-resistant pathogens include timing and type of surgical management, wide use of antimicrobial drugs, and the presence of metallic or organic fragments in the wound. Nosocomial transmission is the most important factor in the spread of multidrug-resistant pathogens. Wound management of war-related injuries merits a multidisciplinary approach. This review aims to describe the microbiology of war-related wound infections and factors affecting their incidence from conflict areas in Iraq, Syria, Israel, and Lebanon.

Factors influencing the regeneration of the mangrove Bruguiera gymnorrhiza (L.) Lamk. on a tropical Pacific island

Krauss, K.W.; Allen, J.A.

2003-01-01

Mangrove swamps occupy approximately two-thirds of the shoreline on Kosrae, Federated States of Micronesia (FSM), and also border the island's most populated areas. Kosraeans depend on mangrove swamps for a supply of wood to support a growing handicraft industry, for a dependable source of fuelwood, and for habitat to support the harvest of fish and mangrove crabs. One of the more prominent mangrove species on Kosrae is Bruguiera gymnorrhiza, yet it is not the most preferred species for carving or cooking. To evaluate B. gymnorrhiza's persistence in the intertidal and to develop a better understanding of factors influencing its regeneration, we investigated predispersal insect colonization of propagules, postdispersal propagule predation by crabs, and the relative effects of natural and artificial shade, salinity, and tidal flooding on early tree seedling survival and growth. Predispersal insect colonization of propagules by boring insects was very high (93%), but the damage did not seem to influence seedling survival. Postdispersal predation of B. gymnorrhiza propagules by crabs was low (17%) and did not change in gap versus understory plots. Predation did vary by intertidal location (lower intertidal > middle intertidal = upper intertidal), with lower predation occurring in an intertidal location with a B. gymnorrhiza-dominated overstory. Shade and tidal inundation reduced seedling growth more than salinity in greenhouse investigations, but sunlight had less positive influence on seedling growth in the field. In general, regeneration and growth occurred successfully under a variety of conditions, indicating that none of the factors investigated serve as strong regulators to B. gymnorrhiza regeneration and early growth on Kosrae. ?? 2002 Elsevier Science B.V.

Reduced large elastic artery stiffness with regular aerobic exercise in middle-aged and older adults: potential role of suppressed nuclear factor κ B signalling.

Aortic pulse-wave velocity (aPWV) increases with age and is a strong independent predictor of incident cardiovascular diseases (CVDs) in healthy middle-aged and older adults. aPWV is lower in middle-aged and older adults who perform regular aerobic exercise than in their sedentary peers. As exercise is associated with reduced systemic inflammation, we hypothesized that suppression of the pro-inflammatory transcription factor nuclear factor κ B (NFκB) may mediate this process. aPWV was measured in young sedentary [n = 10, blood pressure (BP) 108 ± 3/59 ± 2 mmHg; mean ± SEM], middle-aged and older sedentary (n = 9, 124 ± 7/73 ± 5 mmHg) and middle-aged and older aerobic exercise-trained (n = 12, 110 ± 4/67 ± 2 mmHg) healthy, nonhypertensive men and women. Baseline aPWV increased with age [626 ± 14 (young sedentary) vs. 859 ± 49 (middle-aged and older sedentary) cm/s, P < 0.001] but was 20% lower in middle-aged and older trained (686 ± 30 cm/s) than in middle-aged and older sedentary (P < 0.005). Short-term (4 days  x  2500-4500 mg) treatment with the NFκB inhibitor salsalate (randomized, placebo-controlled cross-over design) reduced aPWV (to 783 ± 44 cm/s, P < 0.05) without changing BP (P = 0.40) or heart rate (P = 0.90) in middle-aged and older sedentary, but had no effect in young sedentary (623 ± 19) or middle-aged and older trained (699 ± 30). Following salsalate treatment, aPWV no longer was significantly different in middle-aged and older sedentary vs. middle-aged and older trained (P = 0.29). The reduction in aPWV with salsalate administration was inversely related to baseline (placebo) aPWV (r = -0.60, P < 0.001). These results support the hypothesis that suppressed NFκB signalling may partially mediate the lower aortic stiffness in middle-aged and older adults who regularly perform aerobic exercise.

Structures that Contribute to Middle-Ear Admittance in Chinchilla

Rosowski, John J.; Ravicz, Michael E.; Songer, Jocelyn E.

2009-01-01

We describe measurements of middle-ear input admittance in chinchillas (Chinchilla lanigera) before and after various manipulations that define the contributions of different middle-ear components to function. The chinchilla’s middle-ear air spaces have a large effect on the low-frequency compliance of the middle ear, and removing the influences of these spaces reveals a highly admittant tympanic membrane and ossicular chain. Measurements of the admittance of the air spaces reveal that the high-degree of segmentation of these spaces has only a small effect on the admittance. Draining the cochlea further increases the middle-ear admittance at low frequencies and removes a low-frequency (less than 300 Hz) level dependence in the admittance. Spontaneous or sound-driven contractions of the middle-ear muscles in deeply anesthetized animals were associated with significant changes in middle-ear admittance. PMID:16944166

This research investigated factors that influenced the engagement of part-time faculty teaching in online nursing programs with their institutions. Of the 257 part-time faculty surveyed, the most significant factor was being supported in decisions regarding student issues, followed by institutional commitment to quality online education. Compensation was moderately influential; a negative factor was requiring too frequent meetings. Understanding factors that influence the engagement of part-time faculty teaching in online nursing programs can help leaders of online programs attract and retain experienced, highly skilled faculty.

Active pharmaceutical ingredients (APIs) can enter the natural environment during manufacture, use and/or disposal, and consequently public concern about their potential adverse impacts in the environment is growing. Despite the bulk of the human population living in Asia and Africa (mostly in low- or middle-income countries), limited work relating to research, development and regulations on APIs in the environment have so far been conducted in these regions. Also, the API manufacturing sector is gradually shifting to countries with lower production costs. This paper focuses mainly on APIs for human consumption and highlights key differences between the low-, middle- and high-income countries, covering factors such as population and demographics, manufacture, prescriptions, treatment, disposal and reuse of waste and wastewater. The striking differences in populations (both human and animal), urbanization, sewer connectivity and other factors have revealed that the environmental compartments receiving the bulk of API residues differ markedly between low- and high-income countries. High sewer connectivity in developed countries allows capture and treatment of the waste stream (point-source). However, in many low- or middle-income countries, sewerage connectivity is generally low and in some areas waste is collected predominantly in septic systems. Consequently, the diffuse-source impact, such as on groundwater from leaking septic systems or on land due to disposal of raw sewage or septage, may be of greater concern. A screening level assessment of potential burdens of APIs in urban and rural environments of countries representing low- and middle-income as well as high-income has been made. Implications for ecological risks of APIs used by humans in lower income countries are discussed. PMID:25405973

Elective induction of labor has been linked to increased rates of prematurity and rising rates of cesarean birth. The purpose of this investigation was to evaluate current trends in induction of labor scholarship focusing on evidence-based factors that influence the practice of elective induction. A key word search was conducted to identify studies on the practice of elective induction of labor. Analysis of the findings included clustering and identification of recurrent themes among the articles with 3 categories being identified. Under each category, the words/phrases were further clustered until a construct could be named. A total of 49 articles met inclusion criteria: 7 patient, 6 maternity care provider, and 4 organization factors emerged. Only 4 of the articles identified were evidence based. Patient factors were divided into preferences/convenience, communication, fear, pressure/influence, trust, external influences, and technology. Provider factors were then divided into practice preferences/convenience, lack of information, financial incentives, fear, patient desire/demand, and technology. Organization factors were divided into lack of enforcement/accountability, hospital culture, scheduling of staff, and market share issues. Currently, there is limited data-based information focused on factors that influence elective induction of labor. Despite patient and provider convenience/preferences being cited in the literature, the evidence does not support this practice. PMID:22843006

Breast cancer incidence rates are rising in Qatar. Although the Qatari government provides subsidised healthcare and screening programmes that reduce cost barriers for residents, breast cancer screening (BCS) practices among women remain low. This study explores the influence of socioeconomic status on BCS among Arab women in Qatar. A multicentre, cross-sectional quantitative survey was conducted with 1063 Arab women (87.5% response rate) in Qatar from March 2011 to July 2011. Women who were 35 years or older and had lived in Qatar for at least 10 years were recruited from seven primary healthcare centres and women's health clinics in urban and semiurban regions of Qatar. Associations between socioeconomic factors and BCS practice were estimated using χ(2) tests and multivariate logistic regression analyses. Findings indicate that less than one-third of the participants practised BCS appropriately, whereas less than half of the participants were familiar with recent BCS guidelines. Married women and women with higher education and income levels were significantly more likely to be aware of and to practise BCS than women who had lower education and income levels. Findings indicate low levels of awareness and low participation rates in BCS among Arab women in Qatar. Socioeconomic factors influence these women's participation in BCS activities. The strongest predictors for BCS practice are higher education and higher income levels. Additional research is needed to explore the impact of economic factors on healthcare seeking behaviours in the Middle Eastern countries that have a high national gross domestic product where healthcare services are free or heavily subsidised by the government; promotion of BCS and intervention strategies in these countries should focus on raising awareness about breast cancer, the cost and benefit of early screening for this disease, particularly among low-income women.

AIMS: To determine which factors influence a clinician's decision to request a necropsy. METHODS: Patient age, confidence in premortem diagnosis, relatives' attitudes, and conditions of necropsy practice were combined factorially (two levels each) in separate medical and surgical questionnaires based on clinical case histories. The interactions between the factors were measured by a repeated measures factorial analysis of variance for each of the two clinical groups. The influence of the clinician's interest in necropsies on these interactions was also examined by a similar method. RESULTS: Necropsies were more likely to be requested on young patients, when diagnostic confidence was low, and when relatives' attitudes were favourable. Conditions of necropsy practice did not affect the likelihood of a request and there was no apparent overall difference in necropsy requests between the two groups of clinicians. The "patient age" and "relatives" factors had less influence on the decision of the surgical group to request necropsy. This was attributed to the opportunity to "see for themselves" at operation and was supported by the finding that surgeons were very likely to request necropsies in the absence of surgical intervention. Clinicians from both groups with a high pre-existing interest in the necropsy were consistently more likely to request necropsies. CONCLUSIONS: The "case history" based questionnaires successfully measured the relative influence of multiple factors in relation to the decision of clinicians to request a necropsy. These findings suggest that any attempt to reverse the decline in necropsy rates should focus on changing the clinician's perception of the value of the modern necropsy. PMID:1556237

To examine the factors that influence women's decisions about the timing of motherhood from a life span perspective. Qualitative. Large Western Canadian city with a high rate of infants born to women aged 35 years and older. 45 Canadian women aged 20 to 48 years. Independence, a stable relationship, and declining fertility influenced women's decisions about the timing of motherhood. Women integrated child developmental transitions into a projected life plan as they considered the timing of motherhood. Partner readiness and family of origin influences played a lesser role. Delayed childbearing has become more socially acceptable, with subsequent negative connotations associated with younger motherhood. Parental benefits have limited influence on the timing of motherhood. Recognition by nurses of the various and complex factors that influence women's decisions about the timing of motherhood may flag the importance of pregnancy-related counseling for woman across the fertility life span. Policy decision makers must be cognizant of the need for additional high-risk obstetric and neonatal health services when societal norms encourage women to delay childbearing in favor of completing education and establishing a career.

Introduction Improving maternal health outcomes remains a priority in Low and Middle Income Countries. With the rapid proliferation of mobile health technologies, there is an increased interest in understanding how these technologies can effectively improve maternal health outcomes particularly maternal health seeking knowledge and behaviors. However, few studies present clear explanations of the program developers’ rationale (theory of change) and contextual factors that could influence program outcomes. This mixed-methods study assesses Mobile for Mothers, a community health workers (CHW) utilized maternal mHealth intervention. We present the program developers’ rationale and utilize it as a framework to guide our study that aimed to identify intervention-related and contextual factors, which influence the observed outcomes of a CHW, utilized mHealth intervention. Materials and methods Quantitative methods (a questionnaire with 740 women who received the intervention and survey of 57 CHWs who utilized the intervention) and qualitative methods (12 interviews and 4 group discussions with CHWs and 20 interviews and 5 group discussions with pregnant and lactating women and 15 interviews and 2 group discussions with men) were conducted. These were used to understand how the mHealth intervention was implemented and to gain insight into contextual factors that potentially influenced the observed intervention outcomes. Results Results were grouped following three categories: (1) perceptions and experiences of CHWs utilizing the mHealth technology; (2) CHW-related outcomes; and (3) contextual factors that influence maternal health-seeking behavior. The overall response of CHWs and community members to the intervention was positive. However, contextual factors like the relationship between the CHWs and their respective communities, the pregnant women’s decision-making power and lack of access due to financial influenced the observed outcomes.

In this paper, we examine concurrent and prospective links between attachment and the Five-Factor Model (FFM) of personality from middle childhood to young adulthood (n = 66). At age 8.5 years, attachment was measured with the Separation Anxiety Test and at 21 years with the Adult Attachment Interview, whereas the personality dimensions were assessed with questionnaires at both time points. The results showed that attachment and personality dimensions are meaningfully related, concurrently and longitudinally. Attachment security in middle childhood was positively related to extraversion and openness, both concurrently and prospectively. Unresolved/disorganized (U/d) attachment was negatively related to conscientiousness and positively related to openness in young adulthood. U/d attachment showed a unique contribution to openness above the observed temporal stability of openness. As attachment security was also associated with openness, the duality of this factor is discussed together with other theoretical considerations regarding attachment theory in relation to the FFM.

Factors influencing internal color of cooked meats.

Suman, Surendranath P; Nair, Mahesh N; Joseph, Poulson; Hunt, Melvin C

2016-10-01

This manuscript overviews the pertinent research on internal color of uncured cooked meats, biochemical processes involved in meat cookery, and fundamental mechanisms governing myoglobin thermal stability. Heat-induced denaturation of myoglobin, responsible for the characteristic dull-brown color of cooked meats, is influenced by a multitude of endogenous (i.e., pH, muscle source, species, redox state) and exogenous (i.e., packaging, ingredients, storage) factors. The interactions between these factors critically influence the internal cooked color and can confuse the consumers, who often perceive cooked color to be a reliable indicator for doneness and safety. While certain phenomena in cooked meat color are cosmetic in nature, others can mislead consumers and result in foodborne illnesses. Research in meat color suggests that processing technologies and cooking practices in industry as well as households influence the internal cooked color. Additionally, the guidelines of many international public health and regulatory authorities recommend using meat thermometers to determine safe cooking endpoint temperature and to ensure product safety.

Warfarin is widely used for patients with non-valvular atrial fibrillation (NVAF). Variations in warfarin control, as measured by time in therapeutic range (TTR), have been reported across different regions and ethnicities, particularly between Western and Asian countries. However, there is limited data on comparative factors influencing warfarin control in Caucasian and Asian patients. Therefore, the aim of this study was to determine warfarin control and potential factors influencing this in patients with NVAF in Australia and Singapore. Retrospective data was collected for patients receiving warfarin for January to June 2014 in Australia and Singapore. TTR was calculated for individuals with mean patient TTR used for analysis. Possible influential factors on TTR were analysed including age, gender, concurrent co-morbidities, and concurrent medication. The mean TTR was significantly higher in Australia (82%) than Singapore (58%). At both sites, chronic kidney disease significantly lowered this TTR. Further factors influencing control were anaemia and age<60years in Australia, and vascular disease, CHA 2 DS 2 -VASc score of 6, and concurrent platelet inhibitor therapy in Singapore. Warfarin control was significantly higher in Australia compared to Singapore, however chronic kidney disease reduced control at both sites. The different levels of control in these two countries, together with patient factors further reducing control may impact on anticoagulant choice in these countries with better outcomes from warfarin in Australia compared to Singapore.

This study examined the production of African-American English (AAE) forms produced by 69 school-aged African-American children from middle socio-economic status (SES) communities to determine if age would influence: (a) the number of different types of AAE tokens and (b) the rate of dialect. Descriptive data revealed that there were more than 20 AAE morpho-syntactic forms collectively used by the children. The findings also indicated that factors of age, gender, and sampling context interacted in a variety of ways to influence these children's production of the number of different types of AAE tokens, and the rate of dialect. Readers should have (1) an increased awareness about the use of AAE forms in school-age children from middle SES homes; (2) a greater understanding of how the production of AAE might be influenced by age, gender, and sampling context.

Purpose To model the sensitivity of the optic nerve head (ONH) biomechanical environment to acute variations in IOP, cerebrospinal fluid pressure (CSFP), and central retinal artery blood pressure (BP). Methods We extended a previously published numerical model of the ONH to include 24 factors representing tissue anatomy and mechanical properties, all three pressures, and constraints on the optic nerve (CON). A total of 8340 models were studied to predict factor influences on 98 responses in a two-step process: a fractional factorial screening analysis to identify the 16 most influential factors, followed by a response surface methodology to predict factor effects in detail. Results The six most influential factors were, in order: IOP, CON, moduli of the sclera, lamina cribrosa (LC) and dura, and CSFP. IOP and CSFP affected different aspects of ONH biomechanics. The strongest influence of CSFP, more than twice that of IOP, was on the rotation of the peripapillary sclera. CSFP had similar influence on LC stretch and compression to moduli of sclera and LC. On some ONHs, CSFP caused large retrolamina deformations and subarachnoid expansion. CON had a strong influence on LC displacement. BP overall influence was 633 times smaller than that of IOP. Conclusions Models predict that IOP and CSFP are the top and sixth most influential factors on ONH biomechanics. Different IOP and CSFP effects suggest that translaminar pressure difference may not be a good parameter to predict biomechanics-related glaucomatous neuropathy. CON may drastically affect the responses relating to gross ONH geometry and should be determined experimentally. PMID:29332130

As the most severe ecological issue in southwest China, karst rocky desertification (KRD) has both threatened and constrained regional sustainable development. Comprehensively understanding the relationship between the evolution of KRD and relevant driving data would provide more information to combat KRD in such complex karst environments. Past studies have been limited in quantifying the relative importance of driving factors influencing fine-scale KRD evolution, and have also lacked insight into their interactive impacts. To address these issues, we have used geographical information system techniques and a geographical detector model to explore the spatial consistency of driving factors and their interactions in relation to the evolution of KRD. Changshun County in China was selected as a representative area for the study. Nine relevant driving factors, including both natural and anthropogenic factors, were studied in regard to their relationships with KRD transformation between 2000 and 2010. Our results demonstrate the relative importance of driving data in influencing the improvement and deterioration of KRD. Lithology, soil type and road influence are identified as the leading factors. Interestingly, to our study at least, there is no significant difference between the impacts of natural and anthropogenic factors influencing KRD improvement, and even natural factors have a higher impact on KRD deterioration. Factors were found to enhance the influence of each other for KRD transformation. In particular, the results show a non-linearly enhanced effect between driving factors, which significantly aggravates KRD. New information found in our study helps to effectively control and restore areas afflicted by KRD.

Solar wind and high energy particle effects in the middle atmosphere

The solar wind variability and high energy particle effects in the neutral middle atmosphere are not much known. These factors are important in the high latitude upper mesosphere, lower thermosphere energy budget. They influence temperature, composition (minor constituents of nitric oxide, ozone), circulation (wind system) and airflow. The vertical and latitudinal structures of such effects, mechanisms of downward penetration of energy and questions of energy abundance are largely to be solved. The most important recent finding seems to be the discovery of the role of highly relativistic electrons in the middle atmosphere at L = 3 - 8 (Baker et al., 1987). The solar wind and high energy particle flux variability appear to form a part of the chain of possible Sun-weather (climate) relationships. The importance of such studies in the nineties is emphasized by their role in big international programs STEP and IGBP - Global Change.

Healthy aging includes physical, psychological, social, and spiritual well-being in later years. The purpose of this study is to identify the psychosocial factors influencing healthy aging and examining their socio-demographic characteristics. Perceived health status, depression, self-esteem, self-achievement, ego-integrity, participation in leisure activities, and loneliness were identified as influential factors in healthy aging. 171 Korean adults aged between 45 and 77 years-old participated in the study. Self-reporting questionnaires were used, followed by descriptive statistics and multiple regressions as inferential statistical analyses. There were significant differences between participants' general characteristics: age, education, religion, housing, hobby, and economic status. The factors related to healthy aging had positive correlation with perceived health status, self-esteem, self-achievements, and leisure activities, and negative correlation with depression and loneliness. The factors influencing healthy aging were depression, leisure activities, perceived health status, ego integrity, and self-achievements. These factors were able to explain 51.9%. According to the results, depression is the factor with the greatest influence on healthy aging. Perceived health status, ego integrity, self-achievement, self-esteem, participation of leisure activities were also influential on healthy aging as beneficial factors.

A brief review of salient factors influencing adult eating behaviour.

PubMed

Emilien, Christine; Hollis, James H

2017-12-01

A better understanding of the factors that influence eating behaviour is of importance as our food choices are associated with the risk of developing chronic diseases such as obesity, CVD, type 2 diabetes or some forms of cancer. In addition, accumulating evidence suggests that the industrial food production system is a major contributor to greenhouse gas emission and may be unsustainable. Therefore, our food choices may also contribute to climate change. By identifying the factors that influence eating behaviour new interventions may be developed, at the individual or population level, to modify eating behaviour and contribute to society's health and environmental goals. Research indicates that eating behaviour is dictated by a complex interaction between physiology, environment, psychology, culture, socio-economics and genetics that is not fully understood. While a growing body of research has identified how several single factors influence eating behaviour, a better understanding of how these factors interact is required to facilitate the developing new models of eating behaviour. Due to the diversity of influences on eating behaviour this would probably necessitate a greater focus on multi-disciplinary research. In the present review, the influence of several salient physiological and environmental factors (largely related to food characteristics) on meal initiation, satiation (meal size) and satiety (inter-meal interval) are briefly discussed. Due to the large literature this review is not exhaustive but illustrates the complexity of eating behaviour. The present review will also highlight several limitations that apply to eating behaviour research.

Water is an essential nutrient for thermoregulation, metabolism, cognition, and overall physiological homeostatic function. However, aging adults display a blunted thirst mechanism and subsequently have an increased risk for dehydration or hyponatremia. Fluid consumption behaviors are modifiable and the importance of practicing adequate drinking behaviors for aging adults is amplified during exercise. Identification of aging adult's hydration beliefs and how they attain hydration advice could provide valuable information into ways to promote better drinking habits to reduce fluid imbalances. Thus, this investigation evaluated the knowledge, beliefs and behaviors of middle-aged cyclists (MA) that were associated with hydration status and drinking behavior, before and during a 164-km mass-participation event (ambient temperature, 33.3±2.8ºC(mean±SD)). This cross-sectional field study retrospectively grouped participants by their second urine specific gravity (Usg) measurement of the event morning prior to a mass participation cycling event. Usg was assessed via handheld refractometer. The Hotter N' Hell Hundred 164-km cycling event in Wichita Falls, Texas during the month of August. 36 male recreational cyclists (age, 53±9 y(mean±SD)). Participants were grouped according their urine specific gravity as either slightly hyperhydrated (SH; n=12, Usg≤1.014), euhydrated (EUH; n=12, Usg, 1.015-1.020), or slightly dehydrated (SD; n=12, Usg≥1.021). Exercise histories and questionnaires were recorded 24-48 h prior to the cycling event. Regardless of pre-event hydration status, all groups experienced a similar body mass loss during the 164-km event and finished with statistically similar exercise times; also, drinking behavior within all groups was influenced by multiple factors. The primary factors associated with MA cyclist drinking behavior were trial and error/personal history and thirst; further, the majority of cyclists (≥65%) in SH, EUH, and SD believed that

Luberda, Kamila; Cleaver, Karen

2017-11-07

A global shortage of organs from children and adults available for transplantation is compounded by the failure of next of kin to consent for organs to be donated after death. Non-modifiable and modifiable factors influence decision-making in this area. Modifiable factors are of interest when examining families' decision-making about the donation of organs from their deceased child. A scoping review was undertaken to determine how modifiable factors influence parental decision-making about organ donation. Thematic analysis identified two themes: interactions with healthcare professionals and pre-disposition to organ donation. Satisfaction with experiences of hospital care, the information provided and the way it was communicated, as well as interactions pertaining to emotional support were all found to be modifiable factors that influenced decision making. Likewise, a predisposition to organ donation and knowing the deceased's wishes were associated with the consent decision. Nurses working in critical care environments need to be able to support parents during this difficult time. This article aims to raise awareness of modifiable factors that influence parental decision-making, highlighting their relevance for children's nursing practice. ©2017 RCN Publishing Company Ltd.

Objective: To investigate the influencing factors for trauma-induced tibial infection in underground coal mine. Methods: A retrospective analysis was performed for the clinical data of 1 090 patients with tibial fracture complicated by bone infection who were injured in underground coal mine and admitted to our hospital from January 1995 to August 2015, including the type of trauma, injured parts, severity, and treatment outcome. The association between risk factors and infection was analyzed. Results: Among the 1 090 patients, 357 had the clinical manifestations of acute and chronic bone infection, 219 had red and swollen legs with heat pain, and 138 experienced skin necrosis, rupture, and discharge of pus. The incidence rates of tibial infection from 1995 to 2001, from 2002 to 2008, and from 2009 to 2015 were 31%, 26.9%, and 20.2%, respectively. The incidence rate of bone infection in the proximal segment of the tibia was significantly higher than that in the middle and distal segments (42.1% vs 18.9%/27.1%, P <0.01) . As for patients with different types of trauma (Gustilo typing) , the patients with type III fracture had a significantly higher incidence rate of bone infection than those with type I/II infection (52.8% vs 21.8%/24.6%, P <0.01) . The incidence rates of bone infection after bone traction, internal fixation with steel plates, fixation with external fixator, and fixation with intramedullary nail were 20.7%, 43.5%, 21.4%, and 26.1%, respectively, suggesting that internal fixation with steel plates had a significantly higher incidence rate of bone infection than other fixation methods ( P <0.01) . The multivariate logistic regression analysis showed that the position of tibial fracture and type of fracture were independent risk factors for bone infection. Conclusion: There is a high incidence rate of trauma-induced tibial infection in workers in underground coal mine. The position of tibial fracture and type of fracture are independent risk factors

Mobile chronic disease management systems (MCDMS) have become increasingly important in recent years, but in China, challenges remain for their adoption. Existing empirical studies have not completely explored the adoption behavior of potential MCDMS users. This article presents a study in which we investigated factors that influence chronically ill patients in China and their families to adopt or decline to use MCDMS. We applied a research model based on the technology acceptance model (TAM) as well as four contextual constructs (perceived disease threat, perceived risk, initial trust, and technology anxiety) to a survey of 279 potential MCDMS service participants in China. Our key findings include: (1) as consistent with current research, both perceived usefulness and perceived ease of use have positive impact on potential users' MCDMS adoption intention; (2) both perceived disease threat and initial trust have positive impact on MCDMS adoption intention; (3) the impact of perceived risk is negative, and technology anxiety has negative impact on perceived ease of use of MCDMS; (4) young people place more importance on their perceptions of usefulness, ease of operation, and disease threat than middle-aged and older users; (5) family members are more influenced by their perception of ease of use and disease threat than chronically ill patients, while chronically ill patients place more importance on perceived usefulness than family members. This article concludes by discussing the implications of our study for research and practice, as well as limitations and future research directions.

Vulnerability assessment and risk perception: the case of the Arieş River Middle Basin

NASA Astrophysics Data System (ADS)

Ozunu, Al.; Botezan, C.

2012-04-01

Vulnerability assessment is influenced by a number of factors, including risk perception. This paper investigates the vulnerability of people living in the middle basin of the Aries river region, a former mining area, to natural and technologic hazards. The mining industry lead to significant environmental changes, which combined with the social problems caused by its decline (high unemployment rate, low income and old age) raised the level of the vulnerability in the area. This case study is unique, as it includes an evaluation of risk perception and its influence on the social vulnerability and resilience of local communities to disasters. Key words: vulnerability assessment, natural hazards, social vulnerability, risk perception

A specific subset of micro RNAs (miRs), including miR-133 and miR-206, is specifically expressed in muscle tissue, so that they are currently defined as muscular miRs (myomiRs). To further elucidate the role of myomiRs in muscle biology, we measured miR-133a and miR-206 in plasma of 28 middle-age recreational athletes. The study population consisted of 28 middle aged, recreation athletes (11 women and 17 men; mean age, 46 years) who completed a 21.1 km, half-marathon. The plasma concentration of miR-133a and miR-206, the serum concentration of creatine kinase (CK) and high-sensitivity (HS) cardiac troponin T (cTnT), as well as capillary lactate, were measured before and immediately after the run. The median serum concentration of total CK (257 versus 175 U/L; p < .001), cTnT (17.8 versus 5.6 ng/L; p < .001), and the plasma values of both miR-133a (4.22 versus 0.64 × 10 -4 ; p < .001) and miR-206 (1.36 versus 0.63 × 10 -4 ; p = .001) were considerably increased immediately after the half-marathon run. In multivariate analysis only post-exercise capillary lactate was found to be independently associated with running time. A significant and independent correlation was observed between plasma variations of the two miRs, but not with other physiological or laboratory parameters. The results of this study suggest that the biological significance of miR-133a and 206 variation after middle-distance running parallels but not overlaps the release of biomarkers of nonspecific tissue damage. Enhanced plasma values of these myomiRs may hence reflect a physiological response to high-intensity and/or prolonged exercise rather than tissue injury.

Influence of organisational culture on the implementation of health sector reforms in low- and middle-income countries: a qualitative interpretive review.

PubMed

Mbau, Rahab; Gilson, Lucy

2018-01-01

Health systems, particularly in low- and middle-income countries, are commonly plagued by poor access, poor performance, inefficient use and inequitable distribution of resources. To improve health system efficiency, equity and effectiveness, the World Development Report of 1993 proposed a first wave of health sector reforms, which has been followed by further waves. Various authors, however, suggest that the early reforms did not lead to the anticipated improvements. They offer, as one plausible explanation for this gap, the limited consideration given to the influence over implementation of the software aspects of the health system, such as organisational culture - which has not previously been fully investigated. To identify, interpret and synthesise existing literature for evidence on organisational culture and how it influences implementation of health sector reforms in low- and middle-income countries. We conducted a systematic search of eight databases: PubMed; Africa-Wide Information, Cumulative Index of Nursing and Allied Health Literature (CINAHL), Econlit, PsycINFO, SocINDEX with full text, Emerald and Scopus. Eight papers were identified. We analysed and synthesised these papers using thematic synthesis. This review indicates the potential influence of dimensions of organisational culture such as power distance, uncertainty avoidance, and in-group and institutional collectivism over the implementation of health sector reforms. This influence is mediated through organisational practices such as communication and feedback, management styles, commitment and participation in decision-making. This interpretive review highlights the dearth of empirical literature around organisational culture and therefore its findings can only be tentative. There is a need for health policymakers and health system researchers to conduct further analysis of organisational culture and change within the health system.

An ecological systems approach to bullying behaviors among middle school students in the United States.

Lee, Chang-Hun

2011-05-01

The aim of this study is to identify an ecological prediction model of bullying behaviors. Based on an ecological systems theory, this study identifies significant factors influencing bullying behaviors at different levels of middle and high school. These levels include the microsystem, mesosystem, exosystem, and macrosystem. More specifically, the ecological factors investigated in this multilevel analysis are individual traits, family experiences, parental involvement, school climate, and community characteristics. Using data collected in 2008 from 485 randomly selected students in a school district, this study identifies a best-fitting structural model of bullying behavior. Findings suggest that the ecological model accounted for a high portion of variance in bullying behaviors. All of the ecological systems as well as individual traits were found to be significant influences on bullying behaviors either directly or indirectly.

Middle-aged and older African American women experience disproportionate rates of functional limitations and disability from osteoarthritis (OA) compared to other racial ethnic groups; however, little is known about what factors contribute to this disparity within African American women. To examine factors associated with physical function and disability among African American women ages 50-80 with OA using the disablement process model. This descriptive study included 120 African American women with OA from the Southwestern region of the United States. Regression techniques were used to model the correlates of physical function and disability and to test a mediation model. BMI and pain severity were significantly related to functional limitations. Depressive symptoms mediated the relationship between racial discrimination and disability. Biological, intra-individual, and extra-individual factors are related to disablement outcomes in this sample of African American women, which is consistent with theory suggesting the need for treatment coupled with environmental modifications. This study can inform the development of future bio-behavioral interventions. Copyright © 2016 Elsevier Inc. All rights reserved.

Maternal Employment and Parenting Through Middle Childhood: Contextualizing Factors

The authors used data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (N = 1,364) to examine maternal work hour status and parenting (sensitivity and learning opportunities) from infancy through middle childhood. Work hour status was conceptualized as nonemployment, part time, and full time. Adjusting for covariates, mothers employed part time had higher sensitivity scores and higher provision of child learning opportunity scores than did mothers who were not employed, and these differences characterized families during early childhood rather than middle childhood. Mothers’ provision of child learning opportunities was greater when employed full time (vs. part time) during early childhood. In addition to child age, mothers’ ethnic minority status and partner status moderated the association between maternal work hour status and mothers’ parenting. In general, the findings supported ideas forwarded by role expansionist theory. PMID:25530631

Sexual protective strategies and condom use in middle-age African American women: A qualitative study

PubMed Central

Smith, Tanyka K.

2015-01-01

The heterosexual transmission of HIV has affected middle-age African American women at alarming rates; yet there is a paucity of research and interventions focused on this population. This study used a qualitative approach to understand middle-age urban African American women’s experiences with HIV-related sexual risk behaviors and to identify the sexual protective strategies they employed to reduce their risk for HIV infection. Ten African American women, ages 45 to 56, were recruited from low-income neighborhoods in New York City. Data were collected using in-depth interviews and analyzed using content analysis. Investigator triangulation and member checking were used to ensure rigor. Five salient themes emerged that highlighted the individual, gender/relationship power factors, and the sociocultural elements that influenced sexual protection or risk-taking behavior. Findings provide new insight into the complexities of HIV sexual risk behavior and can guide future HIV prevention interventions for middle-age, African American, urban women. PMID:26194973

A tuition-free teacher candidate is an undergraduate who receives tuition-free teacher education and must work as a teacher in a middle school after their graduation. Tuition-free candidates are of the focus of many researchers; however, no study reports how tuition-free teacher candidates think about teachers. The present study explored stereotypes about middle school and university teachers held by teacher candidates. Specifically, we looked for the differences between the stereotypes held by the teacher candidates and general undergraduates. This study attempted to provide a potential tool to predict the actual willingness of teacher candidates to work as middle school teachers. University and middle school teachers were evaluated using descriptive phrases or words on a five-point Likert scale by 116 tuition-free teacher candidates and 155 general undergraduates. Exploratory factor analyses revealed a three-factor stereotype model including occupational cognition, occupational personality, and occupational emotion. Compared with general undergraduates, teacher candidates held more positive occupational personality and emotions toward middle school teachers; they held more negative occupational emotions toward university teachers. Further, the undergraduates' willingness to be middle school teachers positively correlated with positive occupational emotions and negatively correlated with negative occupational personality and emotions toward middle school teachers. This supported previous studies that individuals' professional willingness were influenced by their stereotypes about professions.

This review aims at identifying barriers to utilization of cervical cancer prevention services in low- and middle-income countries. An electronic search was conducted using the following key words, HPV vaccination, screening, barriers, utilization and low and middle income/developed countries. Using the Garrard (1999) Matrix method approach, a modified matrix was designed and used as a data collection tool and data related to each category listed on the tool were entered into a matrix containing columns reflecting the categories. Constant comparative analysis was used to identify thematic categories. 31 articles published between 2001 and 2014 were yielded from the search. Analysis of the contents of the articles showed that the underutilization of cervical cancer screening services in low and middle-income countries is the result of barriers in accessing and utilizing of the prevention services. Though not mutually exclusive, the barriers were categorized in three categories; individual, community and health system related. Individual barriers include lack of awareness and knowledge about risk factors and prevention of cervical cancer. Age, marital status, diffidence, social economic status, cultural and religious belief of the women also determine the women's' willingness to utilize the services. In some communities there is stigma attached to discussing reproductive health issues and this limits the young women's awareness of cervical cancer and its prevention. Understanding individual, community and health system barriers that hinder women's utilization of cervical cancer prevention services is very crucial in designing effective cervical cancer control programs in low- and middle-income countries.

2018-04-09

Cardiovascular disease is the most common cause of death in Western countries. Physician adherence to guidelines is often suboptimal, resulting in impaired patient outcome and prognosis. Multiple studies have been conducted to evaluate patterns and the influencing factors of patient adherence, but little is known about factors influencing physician guideline adherence. This review aims to identify factors influencing physician guideline adherence relevant to cardiology and to provide insights and suggestions for future improvement. Physician adherence was measured as adherence to standard local medical practice and applicable guidelines. Female gender and older age had a negative effect on physician guideline adherence. In addition, independent of the type of heart disease, physicians without cardiologic specialization were linked to physician noncompliance. Also, guideline adherence in primary care centers was at a lower level compared to secondary or tertiary care centers. The importance of guideline adherence increases as patients age, and complex diseases and comorbidity arise. Appropriate resources and interventions, taking important factors for nonadherence in account, are necessary to improve guideline adoption and adherence in every level of the chain. This in turn should improve patient outcome.

2015-09-01

This study examined the reliability and validity of a parent rating scale, the Self-Regulation Strategy Inventory: Parent Rating Scale (SRSI-PRS), using a sample of 451 parents of sixth- and seventh-grade middle-school students. Principal axis factoring (PAF) analysis revealed a 3-factor structure for the 23-item SRSI-PRS: (a) Managing Behavior and Learning (α = .92), (b) Maladaptive Regulatory Behaviors (α = .76), and (c) Managing Environment (α = .84). The majority of the observed relations between these 3 subscales, and the SRSI-SR, student motivation beliefs, and student mathematics grades were statistically significant and in the small to medium range. After controlling for various student variables and motivation indices of parental involvement, 2 SRSI-PRS factors (Managing Behavior and Learning, Maladaptive Regulatory Behaviors) reliably predicted students' achievement in their mathematics course. This study provides initial support for the validity and reliability of the SRSI-PRS and underscores the advantages of obtaining parental ratings of students' SRL behaviors.

2014-01-01

Background Evidence suggests that top managers’ support influences middle managers’ commitment to innovation implementation. What remains unclear is how top managers’ support influences middle managers’ commitment. Results may be used to improve dismal rates of innovation implementation. Methods We used a mixed-method sequential design. We surveyed (n = 120) and interviewed (n = 16) middle managers implementing an innovation intended to reduce health disparities in 120 US health centers to assess whether top managers’ support influences middle managers’ commitment directly, by allocating implementation policies and practices, or by moderating the influence of implementation policies and practices on middle managers’ commitment. For quantitative analyses, multivariable regression assessed direct and moderated effects; a mediation model assessed mediating effects. We used template analysis to assess qualitative data. Findings We found support for each hypothesized relationship: Results suggest that top managers increase middle managers’ commitment by directly conveying to middle managers that innovation implementation is an organizational priority (β = 0.37, p = 0.09); allocating implementation policies and practices including performance reviews, human resources, training, and funding (bootstrapped estimate for performance reviews = 0.09; 95 percent CI: 0.03, 0.17); and encouraging middle managers to leverage performance reviews and human resources to achieve innovation implementation. Practice Implications Top managers can demonstrate their support by directly conveying to middle managers that an initiative is an organizational priority, allocating implementation policies and practices such as human resources and funding to facilitate innovation implementation, and convincing middle managers that innovation implementation is possible using available implementation policies and practices. Middle managers may maximize the influence of top managers�

Objective To determine epidemiology of cardiovascular risk factors according to geographic distribution and macrolevel social development index among urban middle class subjects in India. Methods We performed cross-sectional surveys in 11 cities in India during years 2005–2009. 6198 subjects aged 20–75 years (men 3426, women 2772, response 62%) were evaluated for cardiovascular risk factors. Cities were grouped according to geographic distribution into northern (3 cities, n = 1321), western (2 cities, n = 1814), southern (3 cities, n = 1237) and eastern (3 cities, n = 1826). They were also grouped according to human social development index into low (3 cities, n = 1794), middle (5 cities, n = 2634) and high (3 cities, n = 1825). Standard definitions were used to determine risk factors. Differences in risk factors were evaluated using χ2 test. Trends were examined by least squares regression. Findings Age–adjusted prevalence (95% confidence intervals) of various risk factors was: low physical activity 42.1% (40.9–43.3), high dietary fat 49.9% (47.8–52.0), low fruit/vegetables 26.9% (25.8–28.0), smoking 10.1% (9.1–11.1), smokeless tobacco use 9.8% (9.1–10.5), overweight 42.9% (41.7–44.1), obesity 11.6% (10.8–12.4), high waist circumference 45.5% (44.3–46.7), high waist–hip ratio 75.7% (74.7–76.8), hypertension 31.6% (30.4–32.8), hypercholesterolemia 25.0% (23.9–26.9), low HDL cholesterol 42.5% (41.3–43.7), hypertriglyceridemia 36.9% (35.7–38.1), diabetes 15.7% (14.8–16.6), and metabolic syndrome 35.7% (34.5–36.9). Compared with national average, prevalence of most risk factors was not significantly different in various geographic regions, however, cities in eastern region had significantly lower prevalence of overweight, hypertension, hypercholesterolemia, diabetes and metabolic syndrome compared with other regions (P < 0.05 for various comparisons).

Nanotechnology can be described as an emerging technology and, as has been the case with other emerging technologies such as genetic modification, different socio-psychological factors will potentially influence societal responses to its development and application. These factors will play an important role in how nanotechnology is developed and commercialised. This article aims to identify expert opinion on factors influencing societal response to applications of nanotechnology. Structured interviews with experts on nanotechnology from North West Europe were conducted using repertory grid methodology in conjunction with generalized Procrustes analysis to examine the psychological constructs underlying societal uptake of 15 key applications of nanotechnology drawn from different areas (e.g. medicine, agriculture and environment, chemical, food, military, sports, and cosmetics). Based on expert judgement, the main factors influencing societal response to different applications of nanotechnology will be the extent to which applications are perceived to be beneficial, useful, and necessary, and how 'real' and physically close to the end-user these applications are perceived to be by the public.

Influence of science and technology magnet middle schools on students' motivation and achievement in science

NASA Astrophysics Data System (ADS)

Allen, David

Some informal discussions among educators regarding motivation of students and academic performance have included the topic of magnet schools. The premise is that a focused theme, such as an aspect of science, positively affects student motivation and academic achievement. However, there is limited research involving magnet schools and their influence on student motivation and academic performance. This study provides empirical data for the discussion about magnet schools influence on motivation and academic ability. This study utilized path analysis in a structural equation modeling framework to simultaneously investigate the relationships between demographic exogenous independent variables, the independent variable of attending a science or technology magnet middle school, and the dependent variables of motivation to learn science and academic achievement in science. Due to the categorical nature of the variables, Bayesian statistical analysis was used to calculate the path coefficients and the standardized effects for each relationship in the model. The coefficients of determination were calculated to determine the amount of variance each path explained. Only five of 21 paths had statistical significance. Only one of the five statistically significant paths (Attended Magnet School to Motivation to Learn Science) explained a noteworthy amount (45.8%) of the variance.

Few studies have been published about the factors influencing return to work after sickness absence. To identify medical and occupational factors influencing the type of fitness certificate given by occupational physicians before employees return to work after sickness absence. A cross-sectional study was undertaken over 3 months in several health services in France. Workers undergoing a medical examination before returning to work after a period of sickness absence of at least 3 weeks were included. Medical and occupational factors were collected using a questionnaire. The relationship between different factors and certification of fitness was assessed by univariate and multivariate analyses. Among the 402 workers included, 64% were considered fit to return to work. Being older, strenuous work, prolonged sick leave and fear of returning to work appeared to be negative factors influencing the return to a previous job. In contrast, having an education level higher than secondary school, being satisfied at work, perception of very good health and benefitting from satisfactory professional relationships appeared to favour return to work. We developed a predictive score of not being fit to return to work after illness. Our study highlighted the relationship between medical and occupational factors with problems returning to work. The predictive score may be used by occupational physicians as a screening tool to identify those who are likely to have difficulties returning to work after illness, so that their working conditions can be modified to take this into consideration.

Food choices established during childhood and adolescence tend to persist into adulthood with consequences for long-term health. Yet, to date, relatively little research has examined factors that influence the food choices of children and adolescents from their perspectives. In this article, previous research is extended by examining developmental differences between children's and adolescents' perceptions of factors influencing their food choices. Focus group discussions were conducted with 29 young people from three age groups (9-10, 13-14 and 16-18 years). An inductive thematic analysis identified three key factors as influencing food choices. These factors included intra-individual factors: the link between food preferences and awareness of healthy eating; intra-familial factors: the role of the home food environment; and extra-familial factors: eating away from the home. Findings indicate that there were developmental differences between children's and adolescents' perceptions of factors influencing food choice. Among adolescents, parental control began to diminish and adolescents exercised increased autonomy over their food choices compared with children. To develop effective nutrition interventions, it is important to gather child and adolescent input regarding factors perceived as influencing their food choices.

Academic Achievement and Risk Factors for Adolescents with Attention-Deficit Hyperactivity Disorder in Middle School and Early High School.

PubMed

Zendarski, Nardia; Sciberras, Emma; Mensah, Fiona; Hiscock, Harriet

Examine academic achievement of students with attention-deficit hyperactivity disorder (ADHD) during the early high school period and identify potentially modifiable risk factors for low achievement. Data were collected through surveys (adolescent, parent, and teacher) and direct assessment of Australian adolescents (12-15 yr; n = 130) with ADHD in early high school (i.e., US middle and high school grades). Academic achievement outcomes were measured by linking to individual performance on the National Assessment Program-Literacy and Numeracy (NAPLAN) tests, direct assessment of reading and math, and teacher report of academic competence. Linear regression models examined associations between adolescent, parent/family, and school factors and NAPLAN domain scores. Students with ADHD had lower NAPLAN scores on all domains and fewer met minimum academic standards in comparison with state benchmarks. The poorest results were for persuasive writing. Poor achievement was associated with lower intelligence quotient across all academic domains. Adolescent inattention, bullying, poor family management, male sex, and attending a low socioeconomic status school were associated with lower achievement on specific domains. Students with ADHD are at increased academic risk during the middle school and early high school period. In addition to academic support, interventions targeting modifiable factors including inattention, bullying, and poor family management may improve academic achievement across this critical period.

The proportion of stroke patients eligible for intravenous or intra-arterial treatment is still limited because many patients do not seek medical help immediately after stroke onset. The aim of our study was to explore which intrinsic factors and considerations influence help-seeking behaviour of relatively healthy participants, confronted with stroke situations. Semi-structured interviews were conducted with 25 non-stroke participants aged 50 years or older. We presented 5 clinical stroke situations as if experienced by the participants themselves. Recognition and interpretation of symptoms were evaluated and various factors influencing help-seeking behaviour were explored in-depth. We used the thematic synthesis method for data analysis. Five themes influencing help-seeking behaviour in a stroke situation were identified: influence of knowledge, views about seriousness, ideas about illness and health, attitudes towards others and beliefs about the emergency medical system. A correct recognition of stroke symptoms or a correct interpretation of the stroke situations did not automatically result in seeking medical help. Interestingly, similar factors could lead to different types of actions between participants. Many intrinsic, as well as social and environmental factors are of influence on help-seeking behaviour in an acute stroke situation. All these factors seem to play a complex role in help-seeking behaviour with considerable inter-individual variations. Accomplishing more patients eligible for acute stroke treatment, future research should focus on better understanding of all factors at various levels grounded in a theory of help-seeking behaviour.

Semantic and pragmatic factors influencing deaf and hearing students' comprehension of english sentences containing numeral quantifiers.

Kelly, Ronald R; Berent, Gerald P

2011-01-01

This research contrasted deaf and hearing students' interpretive knowledge of English sentences containing numeral quantifier phrases and indefinite noun phrases. A multiple-interpretation picture task methodology was used to assess 305 participants' judgments of the compatibility of sentence meanings with depicted discourse contexts. Participants' performance was assessed on the basis of hearing level (deaf, hearing) and grade level (middle school, high school, college). The deaf students were predicted to have differential access to specific sentence interpretations in accordance with the relative derivational complexity of the targeted sentence types. Hypotheses based on the pressures of derivational economy on acquisition were largely supported. The results also revealed that the deaf participants tended to overactivate pragmatic processes that yielded principled, though non-target, sentence interpretations. Collectively, the results not only contribute to the understanding of English acquisition under conditions of restricted access to spoken language input, they also suggest that pragmatic factors may play a broad role in influencing, and compromising, deaf students' reading comprehension and written expression.

External price referencing (EPR) is applied frequently to control pharmaceutical prices. Our objective was to analyse how EPR is used in Middle Eastern (ME) countries and to compare the price corridor for original pharmaceuticals to non-pharmaceutical services not subjected to EPR. We conducted a survey on EPR regulations and collected prices of 16 patented pharmaceuticals and 14 non-pharmaceutical services in seven Middle Eastern (ME) countries. Maximum and minimum prices of each pharmaceutical and non-pharmaceutical technology were compared to mean prices in the countries studied by using market exchange rates. Influencing factors of pharmaceutical prices were assessed by multivariate linear regression analysis. The average price corridor is narrower for pharmaceuticals (-39.8%; +35.9%) than for outpatient and hospital services (-81.7%; +96.3%). Our analysis revealed the importance of population size and EPR implementation on drug price levels; however, EPR results in higher pharmaceutical prices in lower-income countries compared to non-pharmaceutical services.

2014-01-01

This study presents a subset of factors and their association with students' achievement in school algebra. The participants were students who had enrolled in 2007 at the ninth year of Greek public education (third year of middle school). A total of 735 students participated (aged 14-15 years) from 37 public secondary schools. The sample consisted of 378 girls (51.4%) and 357 boys (48.6%). A written algebra test and a questionnaire including demographic survey items were used to collect data. The results show that attitude towards mathematics (ATM) and the current teacher rating of mathematics performance were identified as the more significant predictors of algebra achievement, contributing by 18.1% and 24.7%, respectively, in total variance of mean at the end of ninth grade.

Political and economic factors influencing contraceptive uptake.

Sai, F T

1993-01-01

International, national and local level politics influence the uptake of contraception through consensuses, laws, financial and moral support or the creation of an enabling atmosphere. Opposition to contraception generally comes from some churches and groups opposed to particular technologies. Socio-economic factors, particularly education, the health care system and the perceived or actual cost of fertility regulation as compared to benefits expected from children also powerfully influence contraceptive use. For many poor women in developing countries their powerlessness in relation to their male partners is an important obstacle.

Central systolic blood pressure (CSBP) is a useful prognostic aid in the reduction and prevention of cardiovascular diseases. However, data regarding the distribution of CSBP in China are not available. The study aimed at assessing the distribution of CSBP and examining its relationship with potential cardiovascular risk factors in the Chinese middle-aged population. A cross-sectional study. A cross-sectional survey on cardiovascular risk factors across China was conducted in 2009-2010. CSBP levels were estimated using the non-invasive BPro device with A-Pulse central aortic systolic pressure software. The study population included 9113 individuals (mean age 49.84 years; 53.37% women). The CSBP levels (mean (standard deviation)) were 119.46 (17.51) mmHg in men and 119.81 (19.29) mmHg in women. CSBP levels were higher in rural than urban and lower in the southern than the northern populations (both P < 0.05). The Han ethnic group had higher CSBP levels than the Tibetans (P < 0.05) but similar to those in the Mongolian, Uyghur, Kazak and Akha groups. Irrespective of gender, the mean CSBP level was higher in individuals with diabetes and hypertension than in those without these disorders (P < 0.05). CSBP was positively associated with cardiovascular risk factors such as age, female gender, body mass index, systolic and diastolic blood pressure, and negatively associated with heart rate. CSBP estimated using the BPro device correlates with various cardiovascular risk factors. Our results may help establish future reference values in the Chinese middle-aged population. © The European Society of Cardiology 2015.

Evidence suggests that the majority of people with suicidality do not seek help. Little systematic evaluation of factors influencing professional help-seeking has been done. To systematically evaluate the factors that influence professional help-seeking for suicidality. Published quantitative and qualitative studies in Medline and PsycInfo databases were reviewed following PRISMA. In all, 55 relevant studies were identified. Of these, 15 studies examined professional help-seeking intentions for perceived suicidal ideation, among people with or without suicidality; 21 studies examined professional help-seeking behavior among people with suicidality; and 19 studies examined suicidal decedents' health services use. Several potential important barriers were identified including high self-reliance, lack of perceived need for treatment, and stigmatizing attitudes toward suicide, toward mental health issues, and toward seeking professional treatment. The presence of suicidality and mental health issues was found to generally decrease help-seeking intentions for perceived suicidal ideation while facilitating actual service use. Social support and informal support from family and friends also played an important role in professional help-seeking. Although the majority of the included studies were of sound quality, some of the factors identified in the review were assessed in relatively few studies, and most of the included studies were conducted in industrialized countries. Further quantitative and qualitative studies examining the potential important factors in broader community samples, especially in developing countries, are needed.

Resilient Parenting of Children at Developmental Risk Across Middle Childhood

PubMed Central

Baker, Bruce L.; Blacher, Jan; Crnic, Keith

2015-01-01

This paper focuses on factors that might influence positive parenting during middle childhood when a parent faces formidable challenges defined herein as “resilient parenting.” Data were obtained from 162 families at child age 5 and 8 years. Using an adapted ABCX model, we examined three risk domains (child developmental delay, child ADHD/ODD diagnosis, and low family income) and three protective factors (mother’s education, health, and optimism). The outcome of interest was positive parenting as coded from mother-child interactions. We hypothesized that each of the risk factors would predict poorer parenting and that higher levels of each protective factor would buffer the risk-parenting relationship. Positive parenting scores decreased across levels of increasing risk. Maternal optimism appeared to be a protective factor for resilient parenting concurrently at age 5 and predictively to age 8, as well as a predictor of positive change in parenting from age 5 to age 8, above and beyond level of risk. Maternal education and health were not significantly protective for positive parenting. Limitations, future directions, and implications for intervention are discussed. PMID:24713516

To provide an overview of factors influencing the acceptance of electronic technologies that support aging in place by community-dwelling older adults. Since technology acceptance factors fluctuate over time, a distinction was made between factors in the pre-implementation stage and factors in the post-implementation stage. A systematic review of mixed studies. Seven major scientific databases (including MEDLINE, Scopus and CINAHL) were searched. Inclusion criteria were as follows: (1) original and peer-reviewed research, (2) qualitative, quantitative or mixed methods research, (3) research in which participants are community-dwelling older adults aged 60 years or older, and (4) research aimed at investigating factors that influence the intention to use or the actual use of electronic technology for aging in place. Three researchers each read the articles and extracted factors. Sixteen out of 2841 articles were included. Most articles investigated acceptance of technology that enhances safety or provides social interaction. The majority of data was based on qualitative research investigating factors in the pre-implementation stage. Acceptance in this stage is influenced by 27 factors, divided into six themes: concerns regarding technology (e.g., high cost, privacy implications and usability factors); expected benefits of technology (e.g., increased safety and perceived usefulness); need for technology (e.g., perceived need and subjective health status); alternatives to technology (e.g., help by family or spouse), social influence (e.g., influence of family, friends and professional caregivers); and characteristics of older adults (e.g., desire to age in place). When comparing these results to qualitative results on post-implementation acceptance, our analysis showed that some factors are persistent while new factors also emerge. Quantitative results showed that a small number of variables have a significant influence in the pre-implementation stage. Fourteen out of

The influence of client–clinician interactions has not been emphasized in hearing health care, despite the extensive evidence of the impact of the provider–patient interaction on health outcomes. The purpose of this study was to identify factors in the client–clinician interaction that may influence hearing aid adoption. Thirteen adults who had received a hearing aid recommendation within the previous 3 months and 10 audiologists participated in a study to generate, sort, and rate the importance of factors in client–clinician interaction that may influence the hearing aid purchase decision. A concept mapping approach was used to define meaningful clusters of factors. Quantitative analysis and qualitative interpretation of the statements resulted in eight concepts. The concepts in order of their importance are (a) Ensuring client comfort, (b) Understanding and meeting client needs, (c) Client-centered traits and actions, (d) Acknowledging client as an individual, (e) Imposing undue pressure and discomfort, (f) Conveying device information by clinician, (g) Supporting choices and shared decision making, and (h) Factors in client readiness. Two overarching themes of client-centered interaction and client empowerment were identified. Results highlight the influence of the client–clinician interaction in hearing aid adoption and suggest the possibility of improving hearing aid adoption by empowering clients through a client-centered interaction.

A significant proportion of worker fatalities within Australia result from truck-related incidents. Truck drivers face a number of health and safety concerns. Safety culture, viewed here as the beliefs, attitudes and values shared by an organisation's workers, which interact with their surrounding context to influence behaviour, may provide a valuable lens for exploring safety-related behaviours in heavy vehicle operations. To date no major research has examined safety culture within heavy vehicle industries. As safety culture provides a means to interpret experiences and generate behaviour, safety culture research should be conducted with an awareness of the context surrounding safety. The current research sought to examine previous health and safety research regarding heavy vehicle operations to profile contextual factors which influence health and safety. A review of 104 peer-reviewed papers was conducted. Findings of these papers were then thematically analysed. A number of behaviours and scenarios linked with crashes and non-crash injuries were identified, along with a selection of health outcomes. Contextual factors which were found to influence these outcomes were explored. These factors were found to originate from government departments, transport organisations, customers and the road and work environment. The identified factors may provide points of interaction, whereby culture may influence health and safety outcomes. Copyright © 2014. Published by Elsevier Ltd.

Influence of organisational culture on the implementation of health sector reforms in low- and middle-income countries: a qualitative interpretive review

PubMed Central

Mbau, Rahab; Gilson, Lucy

2018-01-01

ABSTRACT Background: Health systems, particularly in low- and middle-income countries, are commonly plagued by poor access, poor performance, inefficient use and inequitable distribution of resources. To improve health system efficiency, equity and effectiveness, the World Development Report of 1993 proposed a first wave of health sector reforms, which has been followed by further waves. Various authors, however, suggest that the early reforms did not lead to the anticipated improvements. They offer, as one plausible explanation for this gap, the limited consideration given to the influence over implementation of the software aspects of the health system, such as organisational culture – which has not previously been fully investigated. Objective: To identify, interpret and synthesise existing literature for evidence on organisational culture and how it influences implementation of health sector reforms in low- and middle-income countries. Methods: We conducted a systematic search of eight databases: PubMed; Africa-Wide Information, Cumulative Index of Nursing and Allied Health Literature (CINAHL), Econlit, PsycINFO, SocINDEX with full text, Emerald and Scopus. Eight papers were identified. We analysed and synthesised these papers using thematic synthesis. Results: This review indicates the potential influence of dimensions of organisational culture such as power distance, uncertainty avoidance, and in-group and institutional collectivism over the implementation of health sector reforms. This influence is mediated through organisational practices such as communication and feedback, management styles, commitment and participation in decision-making. Conclusion: This interpretive review highlights the dearth of empirical literature around organisational culture and therefore its findings can only be tentative. There is a need for health policymakers and health system researchers to conduct further analysis of organisational culture and change within the health

Evidence suggests that top managers' support influences middle managers' commitment to innovation implementation. What remains unclear is how top managers' support influences middle managers' commitment. Results may be used to improve dismal rates of innovation implementation. We used a mixed-method sequential design. We surveyed (n = 120) and interviewed (n = 16) middle managers implementing an innovation intended to reduce health disparities in 120 U.S. health centers to assess whether top managers' support directly influences middle managers' commitment; by allocating implementation policies and practices; or by moderating the influence of implementation policies and practices on middle managers' commitment. For quantitative analyses, multivariable regression assessed direct and moderated effects; a mediation model assessed mediating effects. We used template analysis to assess qualitative data. We found support for each hypothesized relationship: Results suggest that top managers increase middle managers' commitment by directly conveying to middle managers that innovation implementation is an organizational priority (β = 0.37, p = .09); allocating implementation policies and practices including performance reviews, human resources, training, and funding (bootstrapped estimate for performance reviews = 0.09; 95% confidence interval [0.03, 0.17]); and encouraging middle managers to leverage performance reviews and human resources to achieve innovation implementation. Top managers can demonstrate their support directly by conveying to middle managers that an initiative is an organizational priority, allocating implementation policies and practices such as human resources and funding to facilitate innovation implementation, and convincing middle managers that innovation implementation is possible using available implementation policies and practices. Middle managers may maximize the influence of top managers' support on their commitment by communicating with top

To elucidate the specialty preferences of Pakistani medical students and the factors which influence medical students to make the decision regarding which specialty to pursue. Both basic sciences and clinical students from four medical colleges of Pakistan, i.e., Dow Medical College, Sindh Medical College, Liaquat National Medical College and Muhammad Medical College, were included in the cross-sectional survey during the period of July 2008 to Jan' 2009. After ethical acceptance, data was collected using convenient sampling technique. The questionnaire covered the following demographic details: 13 common specialties and 15 influencing factors. Questionnaires included in the analysis were 771. Most students gave preference to surgery and its associated sub-specialties (50.3%) followed by internal medicine (26.8%), paediatrics (23.2%), dermatology (16.7%), gynaecology and obstetrics (16.7%), psychiatry (13.1%), radiology (10.8%), ENT (8.8%), anaesthesiology (8.7%), administrative medicine (8.6%), orthopaedics (8.2%), ophthalmology (7.5%), and laboratory medicine (6.1%). The highly considered factors (regarding specialties) chosen by 70% of the medical students were: applicable to respective personalities of the individuals, prestige and respect, international opportunities, and time commitment. Surgical-skills, job availability, financial rating, academic performance, and a role model were moderately influencing factors. Hospital environment, parents, general practice, peer-pressure and personal health were the least influential. This trend suggests competition in surgery and its sub-specialties along with internal medicine, paediatrics, dermatology, gynaecology and obstetrics. Specialty suited to personality, time commitment, prestige/respect and international opportunity, influenced more than 70% of the students.

There is a growing recognition that training is not translated into performance and the 'transfer problem' exists in organization training today. Although factors contributing to training transfer have been identified in business and industry, the factors influencing training transfer in nursing profession remain less clear. A qualitative descriptive study was undertaken in two tertiary referral hospitals in China from February 2013 to September 2013. Purposeful sampling of 24 nursing staffs were interviewed about the factors influencing training transfer. Seven themes evolved from the analysis, categorized in 4 main domains, which described the factors influencing training transfer in nursing profession in trainee characteristics, training design, work environment and profession domain. The trainee characteristics domain included attitude and ability. The training design domain included training content and instruction method. The work environment domain included supports as facilitators and opposition as hindrance. The theme pertaining to the profession domain was professional development. Health care managers need to understand the factors influencing training transfer for maximizing the benefits of training. The right beliefs and values about training, the rigorous employee selection for training, the relevance of training content, training instructions facilitating learning and transfer, supports from peer, supervisors and the organization, organizational culture such as change, sharing, learning and support, and professional development are key to successful training transfer. Furthermore, managers should be aware of the opposition from co-workers and find ways to prevent it.

Insight into factors that influence antibiotic prescribing is crucial when developing interventions aimed at a more rational use of antibiotics. We examined factors that influence antibiotic prescribing in long-term care facilities, and present a conceptual model that integrates these factors. Semi-structured qualitative interviews were conducted with physicians (n = 13) and nursing staff (n = 13) in five nursing homes and two residential care homes in the central-west region of the Netherlands. An iterative analysis was applied to interviews with physicians to identify and categorize factors that influence antibiotic prescribing, and to integrate these into a conceptual model. This conceptual model was triangulated with the perspectives of nursing staff. The analysis resulted in the identification of six categories of factors that can influence the antibiotic prescribing decision: the clinical situation, advance care plans, utilization of diagnostic resources, physicians' perceived risks, influence of others, and influence of the environment. Each category comprises several factors that may influence the decision to prescribe or not prescribe antibiotics directly (e.g. pressure of patients' family leading to antibiotic prescribing) or indirectly via influence on other factors (e.g. unfamiliarity with patients resulting in a higher physician perceived risk of non-treatment, in turn resulting in a higher tendency to prescribe antibiotics). Our interview study shows that several non-rational factors may affect antibiotic prescribing decision making in long-term care facilities, suggesting opportunities to reduce inappropriate antibiotic use. We developed a conceptual model that integrates the identified categories of influencing factors and shows the relationships between those categories. This model may be used as a practical tool in long-term care facilities to identify local factors potentially leading to inappropriate prescribing, and to subsequently

Factors that influence women's dispositions toward science

NASA Astrophysics Data System (ADS)

Atria, Catherine Graczyk

Females have been underrepresented in the study of science and science careers for decades although advancements have been made in closing this gender gap, the gap persists particularly in the physical sciences. Variables which influence a woman's desire to pursue and maintain a science course of study and career must be discovered. The United States lags behind other industrialized countries in the fields of science, math, and engineering. Females comprise an estimated half of the population; their potential contributions cannot be ignored or overlooked. This retrospective research study explores the personal experiences of ten women enrolled in science majors, with science related career plans. The goal of this study is to describe the factors that influence the participants' interest in science. The findings, the effect of science coursework, science teachers' personality and manner, other influential educational personnel, role models and mentors, external influences exclusive of school, parental influence, locus of control and positive attitudes toward science confirm what other researchers have found.

To examine the association between self-reported sleep duration (SD) and peer/individual factors predictive of risky behaviors (risk behavior factors) in a large socioeconomically diverse school-based sample of early adolescents. Survey data collected from 10718 and 11240 eighth-grade students in 2010 and 2012, respectively, were analyzed. N/A. Self-reported school night SD was grouped as ≤4 hours, 5 hours, 6 hours, 7 hours, 8 hours, 9 hours, and ≥10 hours. Scores on 10 peer/individual risk behavior factor scales were dichotomized according to national eigth-grade cut points. The percentage of students reporting an "optimal" SD of 9 hours was 14.8% and 15.6% in 2010 and 2012, respectively; 45.6% and 46.1% reported <7 hours. Adjusted for covariates of gender, race, and SES, multilevel logistic regression results showed that odds ratios (ORs) for 9 of 10 risk factor scales increased with SD <7 hours, with a dose-response effect for each hour less sleep compared to an SD of 9 hours. For example, ORs for students sleeping <7 hours ranged from 1.3 (early initiation of antisocial behavior) to 1.8 (early initiation of drug use). The risk factor scale ORs for <5 hours SD ranged from 3.0 (sensation seeking) to 6.4 (gang involvement). Middle school students are at high risk of insufficient sleep; in particular, an SD <7 hours is associated with increased risk behavior factors. © Sleep Research Society 2016.

The aim of this study was to understand factors that influence post-traumatic stress (PTS) in Korean forensic science investigators. A total of 111 forensic science investigators were recruited in Korea. PTS was measured using the tool modified by Choi (2001) from the original developed by Foa, Riggs, Dancu, and Rothbaum (1993) based on DSM-IV. Factors influencing PTS included demographic and job-related characteristics, emotional intelligence, and death anxiety. PTS scores were positively correlated with personality type, fatigue from work, and death anxiety. PTS scores were negatively correlated with length of career as a forensic science investigator and emotional intelligence. The factors that had the greatest influence on PTS were death anxiety, years spent as a forensic science investigator, personality type, emotional intelligence, fatigue, and homicide experience. The explanatory power of these six factors was 44.0%. Therefore, it is necessary to regularly evaluate the mental health of those who are vulnerable to PTS. Based on these results, various interventions could be implemented for promoting overall health of the forensic science investigators. Copyright © 2013. Published by Elsevier B.V.

NASA Astrophysics Data System (ADS)

Wiles, Jason R.

This investigation explored scientific, religious, and otherwise nonscientific factors that may influence student acceptance of biological evolution and related concepts, how students perceived these factors to have influenced their levels of acceptance of evolution and changes therein, and what patterns arose among students' articulations of how their levels of acceptance of evolution may have changed. This exploration also measured the extent to which students' levels of acceptance changed following a treatment designed to address factors identified as potentially affecting student acceptance of evolution. Acceptance of evolution was measured using the MATE instrument (Rutledge and Warden, 1999; Rutledge and Sadler, 2007) among participants enrolled in a secondary-level academic program during the summer prior to their final year of high school and as they transitioned to the post-secondary level. Student acceptance of evolution was measured to be significantly higher than pre-treatment levels both immediately following and slightly over one year after treatment. Qualitative data from informal questionnaires, from formal course evaluations, and from semi-structured interviews of students engaged in secondary level education and former students at various stages of post-secondary education confirmed that the suspected factors were perceived by participants to have influenced their levels of acceptance of evolution. Furthermore, participant reports provided insight regarding the relative effects they perceived these factors to have had on their evolution acceptance levels. Additionally, many participants reported that their science teachers in public schools had avoided, omitted, or denigrated evolution during instruction, and several of these students expressed frustration regarding what they perceived to have been a lack of education of an important scientific principle. Finally, no students expressed feelings of being offended by having been taught about

To identify and describe the array of factors that influence a workers' decision to wear personal protective eyewear (PPE) and the barriers that exist in preventing their use. A series of focus groups enrolled workers and supervisors primarily from manufacturing, construction, or service/retail industries that had potential exposure to eye injury hazards in their job tasks. Focus group sessions were facilitated to collect qualitative and quantitative data in two categories, "sought information" and "emergent themes", related to the factors influencing use of PPE. We conducted a series of 7 groups with 51 participants, 36 (71%) males and 15 (29%) females ranging in age from 19 to 64 years old, from a variety of occupations including construction (24%), production (22%), installation, repair and maintenance (14%), and healthcare (10%). Most were highly experienced in their occupation (>10 years); males (86%) and females (53%), and had received some safety training in the past (82%). The majority of workers in this study were required to wear PPE on their worksite (78%), however only 55% had a dedicated safety officer. A conceptual model that summarizes the "sought information" and "emergent themes" is presented that depicts the decision making process for the factors influencing use of PPE and consists of three primary branches; perceptions of hazards and risks, "barriers" to PPE usage, and enforcement and reinforcement. Lack of comfort/fit, and fogging and scratching of the eyewear were suggested as the most important barriers to PPE usage. Younger age and lack of safety training were other important factors affecting use of PPE. Several potentially modifiable factors identified would lead to an increase in workers' PPE use and encourage supervisors to provide ongoing positive feedback on the continuous use of PPE by workers at risk for an eye injury.

To evaluate the factors which influence the decision to pursue a career in neurology. An anonymous survey was developed using a Likert scale to rate responses. The survey was sent to adult and child neurology faculty, residents and fellows, as well as medical students applying for neurology. Descriptive statistics were used to analyse the factors of influence. Respondents were subsequently categorized into pre-neurology trainees, neurology trainees, child neurologists and adult neurologists, and differences between the groups were analysed using Pearson's chi-square test. One hundred and thirty-three anonymous responses were received. The respondents were neurologists across all levels of training and practice. Across all respondents, the most common factor of high importance was intellectual content of specialty, challenging diagnostic problems, type of patient encountered and interest in helping people. Responses were similar across the groups; however, the earliest trainees cited interest in helping people as most important, while those in neurology training and beyond cite intellectual content of the specialty as most important. As trainees transition from their earliest levels of clinical experience into working as residents and faculty, there is a shift in the cited important factors. Lifestyle and financial factors seem to be the least motivating across all groups. Encouragement from peers, mentors, faculty and practicing physicians is considered high influences in a smaller number of neurologists. This may present an opportunity for practicing neurologists to make connections with medical students early in their education in an effort to encourage and mentor candidates.

Urban subjects have high burden of cardiovascular risk factors, therefore, to evaluate risk factors in middle socioeconomic subjects and to study secular trends we performed an epidemiological study. The study was performed at urban middle class locations defined according to municipal records in years 2009-10. Stratified random sampling using house-to-house survey was performed. Details of medical history, anthropometry and clinical examination were recorded and biochemical tests performed for estimation of fasting glucose and lipids. Current definitions were used for risk factor classification. Descriptive statistics are provided. Trends were calculated using ANOVA or Mantel Haenszel chi-square. Univariate and multivariate logistic regression was performed to assess risk factor determinants. To determine secular trends we compared risk factors with previous cross-sectional studies performed in same locations in years 2002-3 and 2004-5 in subjects 20-59 years age. We evaluated 739 subjects (men 451, women 288, response 67%). Age-adjusted prevalence (%) of risk factors in men and women respectively was smoking 95 (21.1) and 12 (4.2), low physical activity 316 (69.6) and 147 (52.3), high fat intake > or = 20 gm/day 278 (73.4) and 171 (68.7), low fruits and vegetables intake < 3 helpings/day 249 (70.3) and 165 (76.4), overweight/obesity 205 (46.2) and 142 (50.7), high waist size 58 (12.9) and 76 (26.6), high waist:hip 143 (31.9) and 154 (53.9), hypertension 177 (39.5) and 71 (24.6), high total cholesterol > or = 200 mg/ dl 148 (33.0) and 93 (32.7), low HDL cholesterol < 40/50 mg/dl 113 (25.1) and 157 (55.3), diabetes 62 (15.5) and 25 (10.8) and metabolic syndrome 109 (25.1) and 61 (22.0). Age-associated increase was observed in body mass index, waist size, waist ratio:hip, systolic blood pressure and fasting and total cholesterol, non-HDL cholesterol and triglycerides in women (Ptrend < 0.01).

Consumer's Online Shopping Influence Factors and Decision-Making Model

NASA Astrophysics Data System (ADS)

Yan, Xiangbin; Dai, Shiliang

Previous research on online consumer behavior has mostly been confined to the perceived risk which is used to explain those barriers for purchasing online. However, perceived benefit is another important factor which influences consumers’ decision when shopping online. As a result, an integrated consumer online shopping decision-making model is developed which contains three elements—Consumer, Product, and Web Site. This model proposed relative factors which influence the consumers’ intention during the online shopping progress, and divided them into two different dimensions—mentally level and material level. We tested those factors with surveys, from both online volunteers and offline paper surveys with more than 200 samples. With the help of SEM, the experimental results show that the proposed model and method can be used to analyze consumer’s online shopping decision-making process effectively.

Due to the need of snow monitoring and the impact of the global change on the snow, on the basis of the traditional research on snow, starting from the perspective of multi-angle polarized reflectance, we analyzed the influencing factors of snow from the incidence zenith angles, the detection zenith angles, the detection azimuth angles, polarized angles, the density of snow, the degree of pollution, and the background of the undersurface. It was found that these factors affected the spectral reflectance values of the snow, and the effect of some factors on the polarization hyperspectral reflectance observation is more evident than in the vertical observation. Among these influencing factors, the pollution of snow leads to an obvious change in the snow reflectance spectrum curve, while other factors have little effect on the shape of the snow reflectance spectrum curve and mainly impact the reflection ratio of the snow. Snow reflectance polarization information has not only important theoretical significance, but also wide application prospect, and provides new ideas and methods for the quantitative research on snow using the remote sensing technology.

Renewable energy is one of the key technologies through which the energy needs of the future can be met in a sustainable and carbon-neutral manner. Increasing the share of renewable energy in the total energy mix of each country is therefore a critical need. While different countries have approached this in different ways, there are some common aspects which influence the pace and effectiveness of renewable energy incorporation. This presentation looks at data and information from 34 selected countries, analyses the patterns, compares the different parameters and identifies the common factors which positively influence renewable energy incorporation. The most successful countries are analysed for their renewable energy performance against their GDP, policy/regulatory initiatives in the field of renewables, landmass, climatic conditions and population to identify the most influencing factors to bring about positive change in renewable energy share.

The Influence Factors and Mechanism of Societal Risk Perception

Zheng, Rui; Shi, Kan; Li, Shu

Risk perception is one of important subjects in management psychology and cognitive psychology. It is of great value in the theory and practice to investigate the societal hazards that the public cares a lot especially in Socio-economic transition period. A survey including 30 hazards and 6 risk attributes was designed and distributed to about 2, 485 residents of 8 districts, Beijing. The major findings are listed as following: Firstly, a scale of societal risk perception was designed and 2 factors were identified (Dread Risk & Unknown Risk). Secondly, structural equation model was used to analyze the influence factors and mechanism of societal risk perception. Risk preference, government support and social justice could influence societal risk perception directly. Government support fully moderated the relationship between government trust and societal risk perception. Societal risk perception influenced life satisfaction, public policy preferences and social development belief.

Flavour is a very important attribute contributing to the sensory quality of meat and meat products. Although the sensory quality of meat includes orthonasal and retronasal aroma, taste, as well as appearance, juiciness and other textural attributes, the focus of this review is primarily on flavour. The influence of species, age, gender, muscle anatomical location, diet, harvesting conditions, ageing of meat, packaging and storage, as well as cooking method on the flavour of game meat are discussed. Very little research is available on the factors influencing the flavour of the meat derived from wild and free-living game species. The aim of this literature review is thus to discuss the key ante- and post-mortem factors that influence the flavour of game meat, with specific focus on wild and free-living South African game species.

A systematic and future-oriented maintenance management requires quality-assured data regarding the condition of the roadway. An important characteristic for assessing the condition of the road surface are cracks [1]. Experience has proven that the road surface temperature and residual humidity can influence the visibility of cracks. To investigate and quantify these influencing factors in more detail, the Federal Ministry of Transport and Digital Infrastructure has implemented a comprehensive research project [2], during which several measurement campaigns were carried out at different seasons and at different temperatures and humidity degrees of the road surface. The visibility of the cracks was assessed using the German approach ZTV ZEB-StB [3]. After evaluating the cracks, the data was synchronized and the network allocation of the geo-referenced raw data was realized. The relevant condition performance indicators were calculated subsequently. For each evaluation section of 100 meters length, the mean road surface temperature was calculated and, if available, the type and year of construction of the surface course was determined. The evaluated data was visualized to establish correlations between the data and the influencing factors. For the statistical analysis of the results, a total of six comparative scenarios were defined in which the influencing factors of road surface temperature and residual humidity were assessed. This paper documents the results of the research project. In order to obtain a uniform and comparable picture of the condition of the road surface over the years and thus to be able to observe the aging process of the road surface, the measurement campaigns are to be carried out under defined conditions. The research project included proposals for defining and further specifying the measurement conditions.

We investigated (1) the moderating role of religiosity in the link between religious affiliation and ethnic discrimination and (2) the moderating roles of religiosity, ethnic identity, and family connectedness in the relations between ethnic discrimination and psychological distress. Our sample consisted of 122 (60% women, 40% men) Middle Eastern/Arab Americans (MEAAs), ranging in age from 18 to 82 years old, who completed an online survey. Muslim identification predicted discrimination for MEAAs with high but not low religiosity. Higher levels of discrimination, more family connectedness, the interaction of discrimination and religiosity, and the interaction of discrimination and family connectedness were unique predictors of psychological distress. Religiosity is a risk factor for experiencing ethnic discrimination among Muslim identified MEAAs. MEAAs who have high religiosity and low to moderate levels of family connectedness are vulnerable to psychological distress associated with ethnic discrimination. © 2018 Wiley Periodicals, Inc.

Spinal sagittal imbalance has been well known risk factor of decreased quality of life in the field of adult spinal deformity. However, the impact of spinal sagittal balance on locomotive syndrome and physical performance in community-living elderly has not yet been clarified. The present study investigated the influence of spinal sagittal alignment on locomotive syndrome (LS) and physical performance in community-living middle-aged and elderly women. A total of 125 women between the age of 40-88 years (mean 66.2 ± 9.7 years) who completed the questionnaires, spinal mouse test, physical examination and physical performance tests in Yakumo study were enrolled in this study. Participants answered the 25-Question Geriatric Locomotive Function Scale (GLFS-25), the visual analog scale (VAS) for low back pain (LBP), knee pain. LS was defined as having a score of >16 points on the GLFS-25. Using spinal mouse, spinal inclination angle (SIA), thoracic kyphosis angle (TKA), lumbar lordosis angle (LLA), sacral slope angle (SSA), thoracic spinal range of motion (TSROM), lumbar spinal range of motion (LSROM) were measured. Timed-up-and-go test (TUG), one-leg standing time with eyes open (OLS), and maximum stride, back muscle strength were also measured. The relationship between spinal sagittal parameters and GLFS-25, VAS and physical performance tests were analyzed. 26 people were diagnosed as LS and 99 were diagnosed as non-LS. LBP and knee pain were greater, physical performance tests were poorer, SIA were greater, LLA were smaller in LS group compared to non-LS group even after adjustment by age. SIA significantly correlated with GLFS-25, TUG, OLS and maximum stride even after adjustment by age. The cutoff value of SIA for locomotive syndrome was 6°. People with a SIA of 6° or greater were grouped as "Inclined" and people with a SIA of less than 6° were grouped as "Non-inclined". 21 people were "Inclined" and 104 were "Non-inclined".

With increasing rates of chronic disease associated with lifestyle behavioural risk factors, there is urgent need for intervention strategies in primary health care. Currently there is a gap in the knowledge of factors that influence the delivery of preventive strategies by General Practitioners (GPs) around interventions for smoking, nutrition, alcohol consumption and physical activity (SNAP). This qualitative study explores the delivery of lifestyle behavioural risk factor screening and management by GPs within a 45-49 year old health check consultation. The aims of this research are to identify the influences affecting GPs' choosing to screen and choosing to manage SNAP lifestyle risk factors, as well as identify influences on screening and management when multiple SNAP factors exist. A total of 29 audio-taped interviews were conducted with 15 GPs and one practice nurse over two stages. Transcripts from the interviews were thematically analysed, and a model of influencing factors on preventive care behaviour was developed using the Theory of Planned Behaviour as a structural framework. GPs felt that assessing smoking status was straightforward, however some found assessing alcohol intake only possible during a formal health check. Diet and physical activity were often inferred from appearance, only being assessed if the patient was overweight. The frequency and thoroughness of assessment were influenced by the GPs' personal interests and perceived congruence with their role, the level of risk to the patient, the capacity of the practice and availability of time. All GPs considered advising and educating patients part of their professional responsibility. However their attempts to motivate patients were influenced by perceptions of their own effectiveness, with smoking causing the most frustration. Active follow-up and referral of patients appeared to depend on the GPs' orientation to preventive care, the patient's motivation, and cost and accessibility of

Specialist postgraduate education improves patient health outcomes, and assists in meeting the emerging specialisation of nursing practice. The aim of this study was to investigate the motivational factors that influence nurses' engagement with hospital-based postgraduate education. The research design was descriptive and exploratory, using a survey method. The survey consisted of demographic details, the Participation Reasons Scale (PRS) and open-ended questions. Thirty-four participants (100%) completed the survey. Of the PRS extrinsic and intrinsic factors, Professional Improvement and Development (Factor 1) and Professional Service (Factor 2), both intrinsic factors, ranked the highest. Therefore, this study identified that intrinsic motivation factors influenced engagement with postgraduate specialty programs for early career nurses. These results highlight the importance of intrinsic motivation factors for a nursing workforce and how this can potentially drive behaviour and decision making. A better understanding of motivation factors across a nurse's career could lead to educational strategies that optimise postgraduate program engagement to better support healthcare delivery and a culture of lifelong learning.

2003-01-01

The development of expertise in sport is the result of successful interaction of biological, psychological, and sociological constraints. This review examines the training and environmental factors that influence the acquisition of sport expertise. Research examining the quality and quantity of training indicate that these two elements are crucial predictors of attainment. In addition, the possession of resources such as parental support and adequate coaching are essential. Social factors such as cultural influences and the relative age effect are also considered as determinants of sport expertise. Although it is evident that environmental factors are essential to the acquisition of high levels of sport development, further research is clearly required. PMID:24616603

In this study, seven random combination sampling strategies were applied to investigate the uncertainties in estimating the hillslope mean soil water content (SWC) and correlation coefficients between the SWC and soil/terrain properties on a tea + bamboo hillslope. One of the sampling strategies is the global random sampling and the other six are the stratified random sampling on the top, middle, toe, top + mid, top + toe and mid + toe slope positions. When each sampling strategy was applied, sample sizes were gradually reduced and each sampling size contained 3000 replicates. Under each sampling size of each sampling strategy, the relative errors (REs) and coefficients of variation (CVs) of the estimated hillslope mean SWC and correlation coefficients between the SWC and soil/terrain properties were calculated to quantify the accuracy and uncertainty. The results showed that the uncertainty of the estimations decreased as the sampling size increasing. However, larger sample sizes were required to reduce the uncertainty in correlation coefficient estimation than in hillslope mean SWC estimation. Under global random sampling, 12 randomly sampled sites on this hillslope were adequate to estimate the hillslope mean SWC with RE and CV ≤10%. However, at least 72 randomly sampled sites were needed to ensure the estimated correlation coefficients with REs and CVs ≤10%. Comparing with all sampling strategies, reducing sampling sites on the middle slope had the least influence on the estimation of hillslope mean SWC and correlation coefficients. Under this strategy, 60 sites (10 on the middle slope and 50 on the top and toe slopes) were enough to ensure the estimated correlation coefficients with REs and CVs ≤10%. This suggested that when designing the SWC sampling, the proportion of sites on the middle slope can be reduced to 16.7% of the total number of sites. Findings of this study will be useful for the optimal SWC sampling design.

We aim to systematically review studies that identify factors influencing cancer treatment decision-making among indigenous peoples. Following the outline suggested by the Preferred Reporting Items for Systematic Review and Meta-analysis, a rigorous systematic review and meta-synthesis were conducted of factors that influence cancer treatment decision-making by indigenous peoples. A total of 733 articles were retrieved from eight databases and a manual search. After screening the titles and abstracts, the full text of 26 articles were critically appraised, resulting in five articles that met inclusion criteria for the review. Because the five articles to be reviewed were qualitative studies, the Critical Appraisal Skills Program toolkit was used to evaluate the methodological quality. A thematic synthesis was employed to identify common themes across the studies. Multiple socio-economic and cultural factors were identified that all had the potential to influence cancer treatment decision-making by indigenous people. These factors were distilled into four themes: spiritual beliefs, cultural influences, communication and existing healthcare systems and structures. Although existing research identified multiple factors influencing decision-making, this review identified that quality studies in this domain are scarce. There is scope for further investigation, both into decision-making factors and into the subsequent design of culturally appropriate programmes and services that meet the needs of indigenous peoples.

Abstract Background This study is concerned with understanding the impact of demographic changes, socioeconomic inequalities, and the availability of health factors on life expectancy (LE) in the low and lower middle income countries. Methods The cross-country data were collected from 91 countries from the United Nations agencies in 2012. LE is the response variable with demographics (total fertility rate, and adolescent fertility rate), socioeconomic status (mean year of schooling, and gross national income per capita), and health factors (physician density, and HIV prevalence rate) are as the three main predictors. Stepwise multiple regression analysis is used to extract the main factors. Results The necessity of more healthcare resources and higher levels of socioeconomic advantages are more likely to increase LE. On the other hand, demographic changes and health factors are more likely to increase LE by way of de-cease fertility rates and disease prevalence. Conclusion These findings suggest that international efforts should aim at increasing LE, especially in the low income countries through the elimination of HIV prevalence, adolescent fertility, and illiteracy.

Abstract Background In order to improve the quality of care of chronically ill patients the traditional boundaries between primary and secondary care are questioned. To demolish these boundaries so-called ‘shared care’ projects have been initiated in which different ways of substitution of care are applied. When these projects end, disease management may offer a solution to expand the achieved co-operation between primary and secondary care. Objective Answering the question: What key factors influence the development and implementation of shared care projects from a management perspective and how are they linked? Theory The theoretical framework is based on the concept of the learning organisation. Design Reference point is a multiple case study that finally becomes a single case study. Data are collected by means of triangulation. The studied cases concern two interrelated Dutch shared care projects for type 2 diabetic patients, that in the end proceed as one disease management project. Results In these cases the predominant key-influencing factors appear to be the project management, commitment and local context, respectively. The factor project management directly links the latter two, albeit managing both appear prerequisites to its success. In practice this implies managing the factors' interdependency by the application of change strategies and tactics in a committed and skilful way. Conclusion Project management, as the most important and active key factor, is advised to cope with the interrelationships of the influencing factors in a gradually more fundamental way by using strategies and tactics that enable learning processes. Then small-scale shared care projects may change into a disease management network at a large scale, which may yield the future blueprint to proceed. PMID:16896415

In order to improve the quality of care of chronically ill patients the traditional boundaries between primary and secondary care are questioned. To demolish these boundaries so-called 'shared care' projects have been initiated in which different ways of substitution of care are applied. When these projects end, disease management may offer a solution to expand the achieved co-operation between primary and secondary care. Answering the question: What key factors influence the development and implementation of shared care projects from a management perspective and how are they linked? The theoretical framework is based on the concept of the learning organisation. Reference point is a multiple case study that finally becomes a single case study. Data are collected by means of triangulation. The studied cases concern two interrelated Dutch shared care projects for type 2 diabetic patients, that in the end proceed as one disease management project. In these cases the predominant key-influencing factors appear to be the project management, commitment and local context, respectively. The factor project management directly links the latter two, albeit managing both appear prerequisites to its success. In practice this implies managing the factors' interdependency by the application of change strategies and tactics in a committed and skillful way. Project management, as the most important and active key factor, is advised to cope with the interrelationships of the influencing factors in a gradually more fundamental way by using strategies and tactics that enable learning processes. Then small-scale shared care projects may change into a disease management network at a large scale, which may yield the future blueprint to proceed.

While workers' safety risk tolerances have been regarded as a main reason for their unsafe behaviors, little is known about why different people have different risk tolerances even when confronting the same situation. The aim of this research is to identify the critical factors and paths that influence workers' safety risk tolerance and to explore how they contribute to accident causal model from a system thinking perceptive. A number of methods were carried out to analyze the data collected through interviews and questionnaire surveys. In the first and second steps of the research, factor identification, factor ranking and factor analysis were carried out, and the results show that workers' safety risk tolerance can be influenced by four groups of factors, namely: (1) personal subjective perception; (2) work knowledge and experiences; (3) work characteristics; and (4) safety management. In the third step of the research, hypothetical influencing path model was developed and tested by using structural equation modeling (SEM). It is found that the effects of external factors (safety management and work characteristics) on risk tolerance are larger than that of internal factors (personal subjective perception and work knowledge & experiences). Specifically, safety management contributes the most to workers' safety risk tolerance through its direct effect and indirect effect; while personal subjective perception comes the second and can act as an intermedia for work characteristics. This research provides an in-depth insight of workers' unsafe behaviors by depicting the contributing factors as shown in the accident causal model developed in this research.

To examine factors associated with weight change and obesity risk in young and middle-aged adults. The Young Finns Study with its 923 women and 792 men aged 24-39 years at baseline were followed for six years. Variables associated with the weight change were investigated with regression models. The average weight change was 0.45 kg/year in women and 0.58 kg/year in men. In women, weight change was steady across all ages. In men, weight changes were more pronounced in younger age groups. In women (weight gain > 2 kg, n = 490), medication for anxiety, low occupational status, high baseline BMI (body mass index), high intake of sweet beverages, high childhood BMI, high salt (NaCl and/or KCl) use, low number of children, low childhood family income, high stature and low level of dependence (a temperament subscale) were associated with increased weight gain (in the order of importance). In men (weight gain > 2 kg, n = 455), high stature, high intake of french fries, low intake of sweet cookies, young age, recent divorce, low intake of cereals, high intake of milk, depressive symptoms, rural childhood origin, high baseline BMI and unemployment were associated with more pronounced weight gain. Sedentarity (screen-time) was associated with weight gain only in young men. Physical activity and genetic risk for high BMI (score of 31 known variants) were not consistently associated with weight change. Socio-economic factors, temperamental and physical characteristics, and some dietary factors are related with weight change in young/middle-aged adults. The weight change occurring in adulthood is also determined by childhood factors, such as high BMI and low family income.

Background There are many discussions about dyslexia based on studies conducted in western countries, and some risk factors to dyslexia, such as gender and home literacy environment, have been widely accepted based on these studies. However, to our knowledge, there are few studies focusing on the risk factors of dyslexia in China. Therefore, the aim of our study was to investigate the prevalence of dyslexia and its potential risk factors. Methods A cross-sectional study was conducted in Qianjiang, a city in Hubei province, China. Two stages sampling strategy was applied to randomly selected 5 districts and 9 primary schools in Qianjiang. In total, 6,350 students participated in this study and there were 5,063 valid student questionnaires obtained for the final analyses. Additional questionnaires (such as Dyslexia Checklist for Chinese Children and Pupil Rating Scale) were used to identify dyslexic children. The chi-square test and multivariate logistic regression were employed to reveal the potential risk factors to dyslexia. Results Our study revealed that the prevalence of dyslexia was 3.9% in Qianjiang city, which is a middle-sized city in China. Among dyslexic children, the gender ratio (boys to girls) was nearly 3∶1. According to the P-value in the multivariate logistic regression, the gender (P<0.01), mother's education level (P<0.01), and learning habits (P<0.01) (active learning, scheduled reading time) were associated with dyslexia. Conclusion The prevalence rate of dyslexic children in middle-sized cities is 3.9%. The potential risk factors of dyslexic children revealed in this study will have a great impact on detecting and treating dyslexic children in China as early as possible, although more studies are still needed to further investigate the risk factors of dyslexic children in China.
