Sample records for changing student demographics

  1. Changing demographics

    International Nuclear Information System (INIS)

    Vetter, B.M.


    This paper reports on changing population demographics, poor academic preparation for and a decreasing interest in engineering among college students which indicates possible shortages ahead, particularly among chemical and petroleum engineers. The talent pool for engineering must be enlarged to include women and minority men, if we are to ensure an adequate future supply for the U.S

  5. Social demographic change and autism. (United States)

    Liu, Kayuet; Zerubavel, Noam; Bearman, Peter


    Parental age at child's birth--which has increased for U.S. children in the 1992-2000 birth cohorts--is strongly associated with an increased risk of autism. By turning a social demographic lens on the historical patterning of concordance among twin pairs, we identify a central mechanism for this association: de novo mutations, which are deletions, insertions, and duplications of DNA in the germ cells that are not present in the parents' DNA. Along the way, we show that a demographic eye on the rising prevalence of autism leads to three major discoveries. First, the estimated heritability of autism has been dramatically overstated. Second, heritability estimates can change over remarkably short periods of time because of increases in germ cell mutations. Third, social demographic change can yield genetic changes that, at the population level, combine to contribute to the increased prevalence of autism.

  6. Changing demographics and shrinking engineering enrollments

    International Nuclear Information System (INIS)

    Vetter, B.M.


    This paper reports that changing U.S. population demographics, poor academic preparation, and a decreasing interest in engineering among college student indicate possible shortages ahead, particularly among chemical and petroleum engineers. If we are to ensure an adequate future supply for the U.S., the engineering talent pool must be enlarged to include women and minority men

  7. Demographic and Economic Changes and Postsecondary Education. (United States)

    Charner, Ivan

    The interaction of demographic and economic shifts has led to, and will continue to effect, changes in the postsecondary education system and institutions. Demographic shifts include aging of the population, more women in the paid labor force, and increased numbers of minorities. Economic shifts include the growth of the information sector,…

  8. Cultural innovations and demographic change. (United States)

    Richerson, Peter J; Boyd, Robert; Bettinger, Robert L


    Demography plays a large role in cultural evolution through its effects on the effective rate of innovation. If we assume that useful inventions are rare, then small isolated societies will have low rates of invention. In small populations, complex technology will tend to be lost as a result of random loss or incomplete transmission (the Tasmanian effect). Large populations have more inventors and are more resistant to loss by chance. If human populations can grow freely, then a population-technology-population positive feedback should occur such that human societies reach a stable growth path on which the rate of growth of technology is limited by the rate of invention. This scenario fits the Holocene to a first approximation, but the late Pleistocene is a great puzzle. Large-brained hominins existed in Africa and west Eurasia for perhaps 150,000 years with, at best, slow rates of technical innovation. The most sophisticated societies of the last glacial period appear after 50,000 years ago and were apparently restricted to west and north-central Eurasia and North Africa. These patterns have no simple, commonly accepted explanation. We argue that increased high-frequency climate change around 70,000-50,000 years ago may have tipped the balance between humans and their competitor-predators, such as lions and wolves, in favor of humans. At the same time, technically sophisticated hunters would tend to overharvest their prey. Perhaps the ephemeral appearance of complex tools and symbolic artifacts in Africa after 100,000 years ago resulted from hunting inventions that allowed human populations to expand temporarily before prey overexploitation led to human population and technology collapse. Sustained human populations of moderate size using distinctively advanced Upper Paleolithic artifacts may have existed in west Eurasia because cold, continental northeastern Eurasia-Beringia acted as a protected reserve for prey populations.

  9. Global demographic change and climate policies

    NARCIS (Netherlands)

    Gerlagh, Reyer; Jaimes, Richard; Motavasseli, Ali


    Between 1950 and 2017, world average life expectancy increased from below-50 to above-70, while the fertility rate dropped from 5 to about 2.5. We develop and calibrate an analytic climate-economy model with overlapping generations to study the effect of such demographic change on capital markets

  10. Patterns of demographic change in the Americas. (United States)

    Ubelaker, D H


    Considerable scholarly debate has focused on the nature of demographic change in the Americas before and after 1492. Recent research on human skeletal samples and related archeological materials suggests that morbidity and mortality were increasing throughout much of the Western Hemisphere before 1492 in response to increased population density, increased sedentism, and changing subsistence. The evidence suggests that after 1492 population reduction was caused not by continental pandemics but by localized or regional epidemics augmented by social and economic disruption. The twentieth century has witnessed remarkable Native American population recovery, fueled both by improvements in health care and changing definitions of "being Indian."

  11. Simulation of Demographic Change in Palestinian Territories (United States)

    Sumour, M. A.; El-Astal, A. H.; Shabat, M. M.; Radwan, M. A.

    Mortality, birth rates and retirement play a major role in demographic changes. In most cases, mortality rates decreased in the past century without noticeable decrease in fertility rates, leading to a significant increase in population growth. In many poor countries like Palestinian Territories the number of births has fallen and the life expectancy increased. In this paper we concentrate on measuring, analyzing and extrapolating the age structure in Palestine a few decades ago into the future. A Fortran program has been designed and used for the simulation and analysis of our statistical data. This study of demographic change in Palestine has shown that Palestinians will have in future problems as the strongest age cohorts are the above-60-year olds. We therefore recommend the increase of both the retirement age and female employment.

  12. Running injuries - changing trends and demographics. (United States)

    Fields, Karl B


    Running injuries are common. Recently the demographic has changed, in that most runners in road races are older and injuries now include those more common in master runners. In particular, Achilles/calf injuries, iliotibial band injury, meniscus injury, and muscle injuries to the hamstrings and quadriceps represent higher percentages of the overall injury mix in recent epidemiologic studies compared with earlier ones. Evidence suggests that running mileage and previous injury are important predictors of running injury. Evidence-based research now helps guide the treatment of iliotibial band, patellofemoral syndrome, and Achilles tendinopathy. The use of topical nitroglycerin in tendinopathy and orthotics for the treatment of patellofemoral syndrome has moderate to strong evidence. Thus, more current knowledge about the changing demographics of runners and the application of research to guide treatment and, eventually, prevent running injury offers hope that clinicians can help reduce the high morbidity associated with long-distance running.

  13. Changing demographics: what to watch for. (United States)

    Morrison, P A


    Four broad demographic transformations: 1) the population's reconfiguration into smaller household units, especially those comprised of persons living alone; 2) changing employment patterns, notably the shift of married women into paid employment and the resulting proliferation of dual-earner families; 3) transformations in the population's age composition; and 4) the geography of growth in terms of regions that will gain or lose population--can be expected to have a profound impact on opportunities and challenges facing the business sector. The number of future households is projected to increase from 88.6 million in 1986 to 101.5 million by 1996. The sharpest gains will be among households headed by persons ranging in age from the late 30s to the early 50s. The fastest growth through the year 2000 is expected to occur in the Mountain states of the US. Business economists should be alert to these demographic analyses both to spot emerging growth markets and to identify long-term strategic issues, especially as the labor market changes. It will be increasingly important to differentiate time-sensitive from price-sensitive consumers.

  14. Population growth, demographic change, and cultural landscapes. (United States)

    Woodgate, G; Sage, C


    The inclusion of both ecological and socioeconomic components within landscapes makes possible the perception of the hierarchical character of landscape organization. A research approach is needed to conceptualize cultural landscapes as the product of interaction between society and nature. Richard Norgaard's 1984 paper on coevolutionary agricultural development attempts to meet this challenge. Coevolution is the interactive synthesis of natural and social mechanisms of change that characterize the relationship between social systems and ecosystems. The relationship between population, consumption, and environmental changes is complex. Currently industrialized countries present the biggest threat to global environmental resources. The issue of carrying capacity is the corollary of population and the environment. It is primarily the technological factor rather than population that needs to be controlled. The relationship between rich and poor countries is determined by superior economic power. An analysis of landscape change is made, tracing the coevolution of society and environment from the end of the feudal era and making comparisons with continental Europe. Over the years since 1945 the need to realize potential economies of scale has resulted in a wholesale loss of woodlands, hedgerows, and small ponds in the UK. In a global context the likely impacts of population growth and demographic change on landscapes will be influenced by such socioeconomic factors as technology and affluence; policies that ignore cause and effect; and the traditional tendency to treat the environment as a waste repository and a supply depot.

  16. Managing diversity: Changing demographics in the engineering workplace

    International Nuclear Information System (INIS)

    Judd, J.C.; Vella, J.J.


    Technological development creates a need for better educated workers with increased basic, analytical, and interpersonal skills. At the same time, both the population of 22-yr olds and the numbers of traditional students who are choosing careers in engineering and science are decreasing, creating a gap between engineering and construction needs and available trained resources. If more and better caliber students are not attracted to engineering, industry is expected to face selective shortages in the future. There is no question that the demographic composition of the next generation of engineers will significantly differ from that of today's engineers. Industry must recognize the changes that are occurring and take action to ensure that there continues to be an adequate supply of technically qualified workers in light of these demographic changes. In its role as adviser and coordinator of industry action, ANS can play a vital role in ensuring that the industry actions are timely and effective. The ANS should form a committee to study the changing composition of future engineers and constructors and formulate an effective action plan that industry can use to continue to attract able, top-performing students to the engineering field

    Full Text Available This study aimed at determining the impact of demographic factors on the Internet usage purposes of high school students. The population of the study consisted of students between 9th and 12th grades from the Anatolian high schools, science high schools, social sciences high schools, sports high schools and fine arts high schools in Turkey. The sample was chosen through the stratified and cluster sampling procedure. The students were chosen randomly depending on the regions of their school attendance. The sample for this research numbered 3170 students. The research was conducted in the second term of the 2014-2015 academic year. The data were obtained through online forms and the bases of participation are honesty, sincerity, and volunteerism. The data collection tool is a questionnaire and a demographic information form prepared by the researchers. Chi-square Automatic Interaction Detector (CHAID analysis was conducted through SPSS in order to determine the demographic factors affecting the purposes of internet usage among high school students. The results of this research show that 9th grade students in Turkey mostly use the Internet to do homework while students from other grades mostly use the Internet for social networking. The male students use the Internet for playing video games more frequently in comparison with female students. Also, socioeconomic status affects the purpose of Internet usage. Hence it is suggested that teachers talking to male students might use the examples of computers and games and with female students they might relate the topics to social media.

  4. Demographic factors associated with moral sensitivity among nursing students. (United States)

    Tuvesson, Hanna; Lützén, Kim


    Today's healthcare environment is often characterized by an ethically demanding work situation, and nursing students need to prepare to meet ethical challenges in their future role. Moral sensitivity is an important aspect of the ethical decision-making process, but little is known regarding nursing students' moral sensitivity and its possible development during nursing education. The aims of this study were to investigate moral sensitivity among nursing students, differences in moral sensitivity according to sample sub-group, and the relation between demographic characteristics of nursing students and moral sensitivity. A convenience sample of 299 nursing students from one university completed a questionnaire comprising questions about demographic information and the revised Moral Sensitivity Questionnaire. With the use of SPSS, non-parametric statistics, including logistic regression models, were used to investigate the relationship between demographic characteristics and moral sensitivity. Ethical considerations: The study followed the regulations according to the Swedish Ethical Review Act and was reviewed by the Ethics Committee of South-East Sweden. The findings showed that mean scores of nursing students' moral sensitivity were found in the middle to upper segment of the rating scale. Multivariate analysis showed that gender (odds ratio = 3.32), age (odds ratio = 2.09; 1.73), and parental status (odds ratio = 0.31) were of relevance to nursing students' moral sensitivity. Academic year was found to be unrelated to moral sensitivity. These demographic aspects should be considered when designing ethics education for nursing students. Future studies should continue to investigate moral sensitivity in nursing students, such as if and how various pedagogical strategies in ethics may contribute to moral sensitivity in nursing students.

  11. Demographic changes of the Visaginas town

    International Nuclear Information System (INIS)

    Kavaliauskas, A.


    The youngest Lithuanian town surrounded by pine forest is situated at the shore of a picturesque lake of Visaginas. The level of radiation of the town and its suburbs doesn't prevail the standards due to the data given by the Lithuanian Department of Environmental Protection. A relatively small, hilly, green, full of lakes areas have all facilities for tourism and recreation. The town's birth is directly linked with the construction of the nuclear power plant. Great number of nuclear energy specialists came here with their families from the East. The specific character of the town determined the ethnic composition of its population. In 1994-1995 there were Russians (59%), Lithuanians (14%), Byelorussian s (11%), Poles (6%), other nationalities (10%). The number of the residents in Visaginas is stable now with a slight tendency of increasing on the number of women. In 1990 the population of Visaginas was 33192, the women comprised 566 more in number than the men, in 1997 of its 33508 people were 1172 more women than the men. Recent Lithuanian social-economic changes greatly influenced the number of inhabitants of the town. In 1987, 3567 new inhabitants arrived to Visaginas and 1588 moved out. The inhabitants who had arrived to Visaginas in 1987 -1996 were 5,5 times less than in 1987, and moved out 5,4 times less also. One half of the inhabitants who moved from Visaginas went abroad. It shows that the mechanic and social mobility of the town's population decreased too. From 1989 to 1996 the main factor in changing the population number was not the natural increase of it but its migration. Then the natural increase lowered 4,8 times. The economic situation of the town is complex and becoming worse. The town was built as a satellite of the power plant. When the construction of the third block was stopped, the building of many objects was not completed. Other industries didn't develop in Visaginas. Most unemployed are the inhabitants at the age of 19-49 (87,9%). The

  15. Demographic attributes and knowledge acquisition among graduate-entry medical students. (United States)

    Finucane, Paul; Flannery, Denise; McGrath, Deirdre; Saunders, Jean


    Recent changes to undergraduate (basic) medical education in Ireland have linked an expansion of student numbers with wide-ranging reforms. Medical schools have broadened access by admitting more mature students from diverse backgrounds and have increased their international student numbers. This has resulted in major changes to the demographic profile of students at Irish medical schools. To determine whether the demographic characteristics of students impact on their academic performance and specifically on their rate of knowledge acquisition. As a formative assessment exercise, we administered a progress test to all students twice each year during a 4 year graduate-entry medical programme. We compared scores over time between students from different age cohorts, of different gender, of different nationalities and from different academic backgrounds. In the 1143 tests taken by 285 students to date, there were no significant differences in the rate of knowledge acquisition between the various groups. Early in the course, students from a non-biological science background performed less well than others but outperformed their peers by the time of graduation. Neither age, gender, nationality nor academic background impacts on the rate of knowledge acquisition among graduate-entry medical students.

  16. Achievement and Demographics of Home School Students: 1998

    Directory of Open Access Journals (Sweden)

    Lawrence M. Rudner


    Full Text Available This report presents the results of the largest survey and testing program for students in home schools to date. In Spring 1998, 20,760 K-12 home school students in 11,930 families were administered either the Iowa Tests of Basic Skills (ITBS or the Tests of Achievement and Proficiency (TAP, depending on their current grade. The parents responded to a questionnaire requesting background and demographic information. Major findings include: the achievement test scores of this group of home school students are exceptionally high--the median scores were typically in the 70th to 80th percentile; 25% of home school students are enrolled one or more grades above their age-level public and private school peers; this group of home school parents has more formal education than parents in the general population; the median income for home school families is significantly higher than that of all families with children in the United States; and almost all home school students are in married couple families. Because this was not a controlled experiment, the study does not demonstrate that home schooling is superior to public or private schools and the results must be interpreted with caution. The report clearly suggests, however, that home school students do quite well in that educational environment.

  17. Asia's demographic miracle: 50 years of unprecedented change. (United States)

    Leete, R; Alam, I


    The demographic landscape of Asia has seen unprecedented changes over the past 50 years. The transition from high to low mortality and fertility rates has made the eventual stabilization of the world's population a real possibility. The demographic success of Asia is associated with the stunning economic and social changes that have taken place during this period. Aside from social and economic improvements, population and health policies also played a major part in shaping the region's demographic transformation. National programs made a substantial contribution to increasing contraceptive use, lowering fertility, and slowing population growth. The success of family planning programs was frequently supported by positive changes in the demand for children. As the initial impact of the recent financial and economic crisis has shown, the Asian demographic miracle cannot be taken for granted. Since mid-1997, the crisis has interrupted and reversed the region's remarkable development gains. Economic downturns often tend to affect the social sectors unevenly. Strengthening the provision of basic social services, including reproductive health and care of the elderly, particularly in poor nations, will remain a challenge in the next century. The establishment of goals, including in areas such as HIV/AIDS, will help Asian countries realize the vision of the International Conference on Population and Development¿s 20-year Programme of Action.

  19. "Hooking up" among college students: demographic and psychosocial correlates. (United States)

    Owen, Jesse J; Rhoades, Galena K; Stanley, Scott M; Fincham, Frank D


    This study investigated 832 college students' experiences with hooking up, a term that refers to a range of physically intimate behavior (e.g., passionate kissing, oral sex, and intercourse) that occurs outside of a committed relationship. Specifically, we examined how five demographic variables (sex, ethnicity, parental income, parental divorce, and religiosity) and six psychosocial factors (e.g., attachment styles, alcohol use, psychological well-being, attitudes about hooking up, and perceptions of the family environment) related to whether individuals had hooked up in the past year. Results showed that similar proportions of men and women had hooked up but students of color were less likely to hook up than Caucasian students. More alcohol use, more favorable attitudes toward hooking up, and higher parental income were associated with a higher likelihood of having hooked up at least once in the past year. Positive, ambivalent, and negative emotional reactions to the hooking up experience(s) were also examined. Women were less likely to report that hooking up was a positive emotional experience than men. Young adults who reported negative and ambivalent emotional reactions to hooking up also reported lower psychological well-being and less favorable attitudes toward hooking up as compared to students who reported a positive hooking up experience. Based on these findings, suggestions for psychoeducational programming are offered. Additionally, directions for future research are provided.

  20. The joint effect of demographic change on growth and agglomeration


    Theresa Grafeneder-Weissteiner


    Recently, there has been wide interest in the "economics" of population aging. Demographic change has crucial consequences for economic behavior; it e.g. implies that consumption and investment decisions vary over the life-cycle. The latter has important implications for economic growth, whereas the former is decisive for the location of economic activity as emphasized in the New Economic Geography (NEG) literature. Both growth and agglomeration processes are, however, themselves interlinked,...

The level of anxiety and interesting in medical course (p<0.001, non-academic study (p=0.007 and a major physical illness (p=0.009 had significant correlations with together. Conclusion: Results showed a high percentage of students anxious. Regarding the relation between anxiety and other problems such as depression and other disorders including failure in educational function, social relationships and lifestyle, Training courses on coping skills for anxiety and stress as well as consulting services and further guidance is recommended for them.

  5. Peripheralisation: The Missing Link in Dealing with Demographic Change?

    Directory of Open Access Journals (Sweden)

    Tim Leibert


    Full Text Available Demographic change is an uneven spatial process in Germany. Depopulation and ageing have become pressing issues in most rural regions. In connection with low population densities and the financial difficulties of municipalities and service providers in rural regions, these demographic trends have led to a discussion about the future provision of services of general interest and – more broadly – the postulate of equal living conditions which was for a long time the basic principle of spatial development in Germany. In this paper, we argue that the peripheralisation approach is a helpful tool to better understand how interaction of out-migration, dependence, disconnection and stigmatisation shape the future of rural regions. We also discuss the impact of peripheralisation on the development and implementation of adaptation strategies. Based on the 3R-model (retrenchment, repositioning, reorganisation, we argue that adaptation strategies can reinforce (retrenchment peripheralisation processes, but also serve as groundwork for the formulation of policies aiming at de-peripheralisation.

  6. Critical thinking skills of undergraduate nursing students: description and demographic predictors. (United States)

    Hunter, Sharyn; Pitt, Victoria; Croce, Nic; Roche, Jan


    This study investigated the critical thinking skills among undergraduate nursing students in Australia to obtain a profile and determine demographic predictors of critical thinking. There is universal agreement that being a critical thinker is an outcome requirement for many accreditation and registering nursing bodies. Most studies provide descriptive statistical information about critical thinking skills while some have studied the changes in critical thinking after an intervention. Limited research about factors that predict critical thinking skills is available. A cross-sectional descriptive study was conducted using convenience sampling. Two hundred and sixty-nine students were recruited across three years of an undergraduate programme in 2009. Most students' age ranged from under 20 to 34 years (58%), 87% were female, 91% were Australian and 23% of first and second year students had nursing associated experience external to the university. Data about critical thinking skills were collected via the Health Science Reasoning Test (HSRT). Linear regression analysis investigated the predictors of nursing students' critical thinking skills. The students in third year had a profile of critical thinking skills comparable with HSRT norms. Year of study predicted higher critical thinking scores for all domains (p<0.001) except the subscale, analysis. Nationality predicted higher scores for total CT skill scores (p<0.001) and subscales, inductive (p=0.001) and deductive reasoning (p=0.001). Nursing associated experience predicted higher scores for the subscale, analysis (p<0.001). Age and gender were not predictive. However, these demographic predictors only accounted for a small variance obtained for the domains of CT skills. An understanding of factors that predict nursing students' CT skills is required. Despite this study finding a number of significant predictors of nursing students' CT skills, there are others yet to be understood. Future research is recommended

  7. The effects of climate change and land-use change on demographic rates and population viability. (United States)

    Selwood, Katherine E; McGeoch, Melodie A; Mac Nally, Ralph


    Understanding the processes that lead to species extinctions is vital for lessening pressures on biodiversity. While species diversity, presence and abundance are most commonly used to measure the effects of human pressures, demographic responses give a more proximal indication of how pressures affect population viability and contribute to extinction risk. We reviewed how demographic rates are affected by the major anthropogenic pressures, changed landscape condition caused by human land use, and climate change. We synthesized the results of 147 empirical studies to compare the relative effect size of climate and landscape condition on birth, death, immigration and emigration rates in plant and animal populations. While changed landscape condition is recognized as the major driver of species declines and losses worldwide, we found that, on average, climate variables had equally strong effects on demographic rates in plant and animal populations. This is significant given that the pressures of climate change will continue to intensify in coming decades. The effects of climate change on some populations may be underestimated because changes in climate conditions during critical windows of species life cycles may have disproportionate effects on demographic rates. The combined pressures of land-use change and climate change may result in species declines and extinctions occurring faster than otherwise predicted, particularly if their effects are multiplicative. © 2014 The Authors.

  8. 'Fair innings' in the face of ageing and demographic change. (United States)

    Hazra, Nisha C; Gulliford, Martin C; Rudisill, Caroline


    There are now 125 million people aged 80 years and over worldwide, projected by the United Nations to grow threefold by 2050. While increases in life expectancy and rapid increases in the older-age population are considered positive developments, the consequential future health care burden represents a leading concern for health services. We revisit Williams' 'fair innings' argument from 1997, in light of technological and demographic changes, and challenge the notion that greater longevity may impose an unfair burden on younger generations. We discuss perspectives on the equity-efficiency trade-off in terms of their implications for the growing over-80 population, as well as society in general. This includes questioning the comparison of treatment cost-effectiveness in younger vs. older populations when using quality-adjusted life years and the transience of life expectancies over generations. While recognising that there will never be a clear consensus regarding societal value judgements, we present empirical evidence on the very elderly that lends support to a stronger anti-ageist stance given current increases in longevity.

  9. The changing demographic pattern of multiple sclerosis epidemiology. (United States)

    Koch-Henriksen, Nils; Sørensen, Per Soelberg


    The uneven distribution of multiple sclerosis (MS) across populations can be attributed to differences in genes and the environment and their interaction. Prevalence and incidence surveys could be affected by inaccuracy of diagnosis and ascertainment, and prevalence also depends on survival. These sources of error might play a part in the geographical and temporal variations. Our literature search and meta-regression analyses indicated an almost universal increase in prevalence and incidence of MS over time; they challenge the well accepted theory of a latitudinal gradient of incidence of MS in Europe and North America, while this gradient is still apparent for Australia and New Zealand; and suggest a general, although not ubiquitous, increase in incidence of MS in females. The latter observation should prompt epidemiological studies to focus on changes in lifestyle in females. New insights into gene-environment and gene-gene interactions complicate interpretations of demographic epidemiology and have made obsolete the idea of simple causative associations between genes or the environment and MS.

  10. Demographic Changes and the Challenge for a Healthy Ageing. (United States)

    Rossini, Paolo Maria; Marra, Camillo


    Demographic changes bring about a wide range of new research fields including policy topics, health, social welfare, work & productivity, urban & rural development, communication tools, and mobility. This new situation requires a new multi-disciplinary approach bringing together different research programs in order to provide solutions for the upcoming challenges. National Health services are now facing a huge shift in the population structure with a predominance of older generations in the total number of citizens. Good health is the most important factor to live independently in old age. A better understanding of ageing processes and the related "plasticity" of individual performance for environmental adaptation, the prevention for age-related illnesses and healthcare strategies are the basis for keeping very old people healthy and active throughout the course of their lives. We will face mainly the biological, cognitive and psychological dimensions of ageing. Afterwards, we will focus on the relationships linking various biological and lifestyle factors - such as nutrition - that are crucial to obtain a comprehensive picture of ageing and to promote preventing strategies against degenerative neurological diseases. Finally we will investigate which interventions - nutritional and physical - could help in keeping people healthy, in particular which factors could promote people's physical, social and psychological functional abilities and the systemic multilevel consequences induced by a healthy ageing.

  11. Environmental stress, resource management and demographic change in Northern Tanzania

    International Nuclear Information System (INIS)

    Niboye, E.P.


    A multitude of environmental problems abound in Tanzania. The problems range from declining land resources, de-vegetation, urban and air pollution, degradation of the marine environment to the destruction of biological diversity. A thorough analysis of these manifestations of environments decline reveal the presence of linkages to economic, political, cultural and demographic constraints which have been at the crux of Tanzania's efforts towards emancipation. We attested that societies are always dialect and integral parts of the global entity. As such the analysis of any societal problem can not be sufficiently tackled by basing on a 'micro level' societal specific factors. We need to expand our horizon and include 'macro level' elements which impinges on the society under study. Imperatively, influences on any environment, social or biophysical, whether positive or negative, emanates either or both from within the specific society and or from without. In our study we set out to provide an insight into the nature and character of man and environment interaction in Arumeru district, Northern Tanzania. We intended to investigate the extent to which changes in the household production patterns as a result of environmental stress and the consequent resource management strategies influence and are hitherto influenced by population growth. The aspects of demographic changes especially patterns of growth and settlement, agrarian production such as land tenure, food and cash crop interventions, non-farm activities and management of the commons were studies. Further, local adaptation to crisis including environmental stress and emerging markets were explored. he theoretical model adopted in analysing the man-land environment relationship in Arumeru district and the ensuing findings, give legitimacy to the position that issues of population growth or decline cannot be separated from questions of economic and social development, or from the environmental concerns related to

  13. Endogenous technological and demographic change under increasing water scarcity (United States)

    Pande, Saket; Ertsen, Maurits; Sivapalan, Murugesu


    The ancient civilization in the Indus Valley civilization dispersed under extreme dry conditions; there are indications that the same holds for many other ancient societies. Even contemporary societies, such as the one in Murrumbidgee river basin in Australia, have started to witness a decline in overall population under increasing water scarcity. Hydroclimatic change may not be the sole predictor of the fate of contemporary societies in water scarce regions and many critics of such (perceived) hydroclimatic determinism have suggested that technological change may ameliorate the effects of increasing water scarcity and as such counter the effects of hydroclimatic changes. To study the role of technological change on the dynamics of coupled human-water systems, we develop a simple overlapping-generations model of endogenous technological and demographic change. We model technological change as an endogenous process that depends on factors such as the investments that are (endogenously) made in a society, the (endogenous) diversification of a society into skilled and unskilled workers, a society's patience in terms of its present consumption vs. future consumption, production technology and the (endogenous) interaction of all of these factors. In the model the population growth rate is programmed to decline once consumption per capita crosses a "survival" threshold. This means we do not treat technology as an exogenous random sequence of events, but instead assume that it results (endogenously) from societal actions. The model demonstrates that technological change may indeed ameliorate the effects of increasing water scarcity but typically it does so only to a certain extent. It is possible that technological change may allow a society to escape the effect of increasing water scarcity, leading to a (super)-exponential rise in technology and population. However, such cases require the rate of success of investment in technological advancement to be high. In other

  14. Demographic change and marriage choices in one Carib family. (United States)

    Adams, K


    The demographic adaptation of a family of Topside Caribs along the Barama River in Guyana was studied. The family history included two grandfather and granddaughter marriages. Jack Raymond's father, who was born in 1870, left Bottomside after the death of his wife in the 1920s and settled above the falls of the Barama River (Topside in Sawari) with the hope of subsistence living off the rain forest. Information on the grandfather generation was made difficult by name changes, general references to all men in the second generation as grandfathers, and the focus on father's and mother's generation. The typical pattern was for brothers to live close by, and intermarry with a family of sisters. Female children married mother's brothers' sons or father's sisters sons. Their children formed their own cluster settlements. The early history indicated economic hardship, loss of wives, and difficulties in remarrying. The Baird chronicles of the reintroduction of gold mining and the ethnography of Gillin indicated that malaria and round worm were diseases affecting the indigenous population during the 1920s and 1930s. The Topside population was supported by the local gold-mining economy, while the Bottomside population suffered economic hardship and high infant mortality. In the Jack Raymond family, remarriage resulted in children marrying cross cousins. The younger daughter married in the 1940s, when subsistence production of cassava and hunting and gold-mining income provided the family's livelihood. The daughter had 10 surviving children, compared to her adoptive mother's two. For the daughter's generation, the first pregnancy occurred between the ages of 18 and 22 years, and birth spacing was 20-30 months for 25 years. Neither polygyny nor monogamy affected the potential for 12 children. In this Baramita Air Strip population in 1971, there were 62 mothers; reproductive histories were available for 59. The changes in reproductive patterns after 1940 were apparent: for

  16. Climate change threatens polar bear populations: a stochastic demographic analysis. (United States)

    Hunter, Christine M; Caswell, Hal; Runge, Michael C; Regehr, Eric V; Amstrup, Steve C; Stirling, Ian


    The polar bear (Ursus maritimus) depends on sea ice for feeding, breeding, and movement. Significant reductions in Arctic sea ice are forecast to continue because of climate warming. We evaluated the impacts of climate change on polar bears in the southern Beaufort Sea by means of a demographic analysis, combining deterministic, stochastic, environment-dependent matrix population models with forecasts of future sea ice conditions from IPCC general circulation models (GCMs). The matrix population models classified individuals by age and breeding status; mothers and dependent cubs were treated as units. Parameter estimates were obtained from a capture-recapture study conducted from 2001 to 2006. Candidate statistical models allowed vital rates to vary with time and as functions of a sea ice covariate. Model averaging was used to produce the vital rate estimates, and a parametric bootstrap procedure was used to quantify model selection and parameter estimation uncertainty. Deterministic models projected population growth in years with more extensive ice coverage (2001-2003) and population decline in years with less ice coverage (2004-2005). LTRE (life table response experiment) analysis showed that the reduction in lambda in years with low sea ice was due primarily to reduced adult female survival, and secondarily to reduced breeding. A stochastic model with two environmental states, good and poor sea ice conditions, projected a declining stochastic growth rate, log lambdas, as the frequency of poor ice years increased. The observed frequency of poor ice years since 1979 would imply log lambdas approximately - 0.01, which agrees with available (albeit crude) observations of population size. The stochastic model was linked to a set of 10 GCMs compiled by the IPCC; the models were chosen for their ability to reproduce historical observations of sea ice and were forced with "business as usual" (A1B) greenhouse gas emissions. The resulting stochastic population

    Full Text Available The paper presents the result of a spatial analysis considering the effect of demographic ageing and ageing-in-place processes in Germany according to spatially differentiated ageing patterns among urban, sub-urban and rural counties up to 2025. As to the latest official population forecast counties of urban core regions will undergo a slower ageing process than other types of counties, resulting in a reversal of ageing patterns. Urban core areas in this analysis will gain demographically from their net migration surplus while suburban housing locations of the past will be no longer able to attract enough young migrants to compensate for their now rapidly ageing baby boomer generation. The process presented is typical for the fate of (suburban housing areas with homogenous populations under conditions of ageing and shrinking if spatial mobility in ageing population groups is declining.

  1. The changing demographic, legal, and technological contexts of political representation. (United States)

    Forest, Benjamin


    Three developments have created challenges for political representation in the U.S. and particularly for the use of territorially based representation (election by district). First, the demographic complexity of the U.S. population has grown both in absolute terms and in terms of residential patterns. Second, legal developments since the 1960s have recognized an increasing number of groups as eligible for voting rights protection. Third, the growing technical capacities of computer technology, particularly Geographic Information Systems, have allowed political parties and other organizations to create election districts with increasingly precise political and demographic characteristics. Scholars have made considerable progress in measuring and evaluating the racial and partisan biases of districting plans, and some states have tried to use Geographic Information Systems technology to produce more representative districts. However, case studies of Texas and Arizona illustrate that such analytic and technical advances have not overcome the basic contradictions that underlie the American system of territorial political representation.

    Emmanuel D Jadhav


    Full Text Available Background: During the 2008-10 economic recession, Kentucky local health department (LHD leaders utilized innovative strategies to maintain their programs. A characteristic of innovative strategy is leader openness to change. Leader demographical research in for-profit organizations has yielded valuable insight into leader openness to change. For LHD leaders the nature of the association between leader demographic and organizational characteristics on leader openness to change is unknown. The objectives of this study are to identify variation in openness to change by leaders’ demographic and organizational characteristics and to characterize the underlying relationships. Material and Methods: The study utilized Spearman rank correlations test to determine relationships between leader openness to change (ACQ and leader and LHD characteristics. To identify differences in the distribution of ACQ scores, Wilcoxon-Mann-Whitney and Kruskal Wallis non-parametric tests were used, and to adjust for potential confounding linear regression analysis was performed.Data: LHD leaders in the Commonwealth of Kentucky were the unit of analysis. Expenditure and revenue data were available from the state health department. National census data was utilized for county level population estimates. A cross-sectional survey was performed of KY LHD leaders’ observable attributes relating to age, gender, race, educational background, leadership experience and openness to change. Results: Leaders had relatively high openness to change scores. Spearman correlations between leader ACQ and departmental 2012-13 revenue and expenditures were statistically significant, as were the differences observed in ACQ by gender and the educational level of the leader. Differences in ACQ score by education level and agency revenue were significant even after adjusting for potential confounders. The analyses imply there are underlying relationships between leader and LHD characteristics

  11. Association between Eating Out and Socio-Demographic Factors of University Students in Chongqing, China. (United States)

    Hu, Ping; Wu, Tingting; Zhang, Fan; Zhang, Yan; Lu, Lu; Zeng, Huan; Shi, Zu-Min; Sharma, Manoj; Xun, Lei; Zhao, Yong


    (1) Objective : We aimed to explore the current situation of eating out and the association with socio-demographic factors of university students in Chongqing, China. (2) Methods : We used self-administered questionnaires to collect information. There are 14 universities in Chongqing; four (Chongqing Medical University, Chongqing University, Chongqing Normal University, and Chongqing University of Science & Technology) were randomly selected. In each selected university, two disciplines were randomly selected. (3) Results : 4595 university students participated in the study. The frequency of eating out was relatively high. The frequency of eating out among females was higher than that among males during weekdays. The two main reasons for eating out were having an opportunity to meet friends (56.0%) and improving diet (39.6%). Bistros (61.7%) and hot-pot restaurants (41.1%) were the favorite places for eating out. Only 36.0% of the participants said they considered nutrition and food safety when selecting restaurants. The majority of the participants demonstrated a high demand for nutrition and food safety knowledge when eating out (77.7%). (4) Conclusions : The higher the monthly living expenses were, the higher the frequency of eating out was. An intervention strategy to reduce the frequency or change the behavior of eating out should be formulated by considering the students' perspectives.

  13. The Interaction of Learning Disability Status and Student Demographic Characteristics on Mathematics Growth. (United States)

    Stevens, Joseph J; Schulte, Ann C

    This study examined mathematics achievement growth of students without disabilities (SWoD) and students with learning disabilities (LD) and tested whether growth and LD status interacted with student demographic characteristics. Growth was estimated in a statewide sample of 79,554 students over Grades 3 to 7. The LD group was significantly lower in achievement in each grade and had less growth than the SWoD group. We also found that student demographic characteristics were significantly related to mathematics growth, but only three demographic characteristics were statistically significant as interactions. We found that LD-SWoD differences at Grade 3 were moderated by student sex, while Black race/ethnicity and free or reduced lunch (FRL) status moderated LD-SWoD differences at all grades. These results provide practitioners and policy makers with more specific information about which particular LD students show faster or slower growth in mathematics. Our results show that simply including predictors in a regression equation may produce different results than direct testing of interactions and achievement gaps may be larger for some LD subgroups of students than previously reported.

  14. Facebook addiction among Turkish college students: the role of psychological health, demographic, and usage characteristics. (United States)

    Koc, Mustafa; Gulyagci, Seval


    This study explored Facebook addiction among Turkish college students and its behavioral, demographic, and psychological health predictors. The Facebook Addiction Scale (FAS) was developed and its construct validity was assessed through factor analyses. A total of 447 students reported their personal information and Facebook usage and completed the FAS and General Health Questionnaire (GHQ-28). The results revealed that weekly time commitment, social motives, severe depression, and anxiety and insomnia positively predicted Facebook addiction. Neither demographic variables nor the interactions of gender by usage characteristics were found to be significant predictors.

    Full Text Available Tourism in any region is closely linked to its demographic potential. North Oltenia is known in Romania for its valuable tourism potential, both natural and anthropic, which caused over time a contiuous diversification of the types of tourism. This study deals with the demographic evolution of the administrative units in North Oltenia, between Tismana and Olt Rivers in the last half of century (1966-2015, analyzing also the age structure and demographic ageing after 1990. The major objectives of this study were to identify the types of demographic change and the hierarchy of the administrative units; the analysis of age structure (youth, adults, elders, especially adults who include the working population capable of sustaining tourist flows in the region and demographic ageing. Mapping the results was designed to quickly identify the administrative units where demographic potential recorded an unfavorable evolution, where tourism potential and maintenance of the existing tourism infrastructure can be more difficult in the future.

  17. United States Changing Demographics - English/Spanish Space Education (United States)

    Leon, R.


    Accordingly the United States Census Bureau, the ethnic group adding the largest number of people to the national population is the Hispanic exceeding 12 percent of the population and growing by almost 60 percent between 1990 and 2000. The status of the nation's educational system with respect to Hispanic students is perhaps one of the most influential issues facing the largest economy of the world. The low income, lack of language skills, highest drop-out rate in the nation, are some of the reasons why Hispanics are less likely to receive a university degree than any other ethical group. In short, the government requires to implement compensatory programs and bilingual education to ensure global leadership. Because of ongoing immigration, Spanish persists longer among Hispanics than it did among other immigrant groups. Spanish is the fourth most spoken language in the world after Mandarin, Hindustani and English. Although not all U.S. Hispanics speak Spanish, almost all U.S. Spanish speakers are Hispanics. This paper is intended to outline the challenging implementation of a bilingual education project affiliated to NASA Johnson Space Center encouraging greater academic success of Hispanics in engineering, math and science. The prospective project covers the overall role of space activities in the development of science and technology, socioeconomic issues and international cooperation. An existent JSC project is the starting stage to keep on developing an interactive video teleconference and web-media technology and produce stimulating learning products in English and Spanish for students and teachers across the nation and around the world.

    Full Text Available (1 Objective: We aimed to explore the current situation of eating out and the association with socio-demographic factors of university students in Chongqing, China. (2 Methods: We used self-administered questionnaires to collect information. There are 14 universities in Chongqing; four (Chongqing Medical University, Chongqing University, Chongqing Normal University, and Chongqing University of Science & Technology were randomly selected. In each selected university, two disciplines were randomly selected. (3 Results: 4595 university students participated in the study. The frequency of eating out was relatively high. The frequency of eating out among females was higher than that among males during weekdays. The two main reasons for eating out were having an opportunity to meet friends (56.0% and improving diet (39.6%. Bistros (61.7% and hot-pot restaurants (41.1% were the favorite places for eating out. Only 36.0% of the participants said they considered nutrition and food safety when selecting restaurants. The majority of the participants demonstrated a high demand for nutrition and food safety knowledge when eating out (77.7%. (4 Conclusions: The higher the monthly living expenses were, the higher the frequency of eating out was. An intervention strategy to reduce the frequency or change the behavior of eating out should be formulated by considering the students’ perspectives.

    This paper analyses the secular changes in the body development patterns of Hungarian children between the 1910s and the beginning of the 2000s in relation to socioeconomic and demographic changes in the country. Individual growth data of children were available from two national growth studies (1983-86, 2003-06), while sample-size weighted means of children's body dimensions were collected through regional studies between the 1920s and 1970s. Gross domestic product, Gini index, life expectancy at birth and under-5 mortality rate were used to assess the changes in economic status, income inequalities of the society and the population's general health status, respectively. Secular changes in food consumption habits were also examined. The positive Hungarian secular changes in socioeconomic status were associated with a continuous increase in children's body dimensions. The negative socioeconomic changes reflected only in wartime and post-war periods of children's growth, and the considerable socioeconomic changes at the beginning of the 1990s did not appear to influence the positive trend in children's growth. The positive secular trend in stature and body mass did not level off at the beginning of the 2000s: the socioeconomic conditions that support optimal growth and maturation could improve in Hungary.

  3. How does variance in fertility change over the demographic transition? (United States)

    Hruschka, Daniel J; Burger, Oskar


    Most work on the human fertility transition has focused on declines in mean fertility. However, understanding changes in the variance of reproductive outcomes can be equally important for evolutionary questions about the heritability of fertility, individual determinants of fertility and changing patterns of reproductive skew. Here, we document how variance in completed fertility among women (45-49 years) differs across 200 surveys in 72 low- to middle-income countries where fertility transitions are currently in progress at various stages. Nearly all (91%) of samples exhibit variance consistent with a Poisson process of fertility, which places systematic, and often severe, theoretical upper bounds on the proportion of variance that can be attributed to individual differences. In contrast to the pattern of total variance, these upper bounds increase from high- to mid-fertility samples, then decline again as samples move from mid to low fertility. Notably, the lowest fertility samples often deviate from a Poisson process. This suggests that as populations move to low fertility their reproduction shifts from a rate-based process to a focus on an ideal number of children. We discuss the implications of these findings for predicting completed fertility from individual-level variables. © 2016 The Author(s).

    activities, we contrast theoretical orientations that see advantages to a division of labour or complementary roles, in comparison to orientations that see less risk and greater companionship in a collaborative model based on sharing paid and unpaid work, or co-providing and co-parenting. It is important to look both inside and outside of families, or at the changing gendered links between earning and caring, to understand change both in families and in the work world. It is proposed that equal opportunity by gender has advanced further in the public sphere associated with education and work, than in the private family sphere associated with everyday life. Time-use data indicate that, on average, men carry their weight in terms of total productive time (paid plus unpaid work, but that women make much more of the accommodations between family and work. Fertility is likely to be lowest in societies that offer women equal opportunity in the public sphere but where families remain traditional in terms of the division of work. Policies are discussed that would reduce the dependency between spouses, and encourage a greater common ground between men and women in earning and caring.

  9. Hmong demographic changes in Laos: causes and ecological consequences. (United States)

    Ireson, W R


    This study of the Hmong in Laos is based on ethnographic research conducted during a three week stay in the Nong Het district of Xieng Khouang province. Information was collected on the household agricultural economy, village and household movement, family composition and change, cropping and animal husbandry, and environmental resources. The study area east of the Mekong River and near the Vietnamese border is an infrequently studied area. Findings differ from the ethnographic literature that portrays the Hmong as migrating frequently as swidden fields are exhausted, as living in large extended families, and as polygynous. The Hmong are the second largest minority in Laos (231,000), but are only 0.1% of Thailand's total population (90,000). There are 558,000 Hmong in Vietnam, but 5 million in China. Most rural Hmong in Laos produce opium as a necessary crop for sustaining their household farming economy. Although areas near the study area were involved in major military action during 1960-73, the study area received minimal disruption. Four studies of the Hmong in Laos and Thailand indicated that the Hmong stayed at one residence about 7 years, that residence varied from 6-16 years, and that settlements were short-lived. Household size ranged from 4 to 47 households. The Hmong in this study were more sedentary. In 1990, the villages averaged about 45 households. The population ranged in age from 19 years to 87 years. The Hmong had a high birth rate and a high mortality rate due to poor diet and lack of adequate medical care. 45% of the Nong Het population were aged under 14 years, which suggests a baby boom after the war. The dependency ratio was very high. Polygyny was uncommon. Of the 154 households, the average size was small at 7.40 persons. 71% were nuclear families. Patrilocal residence after marriage was still practiced, but the time spent in the father's home was reduced. The findings suggest that the Hmong are likely to become sedentary due to limits on

    Full Text Available The subject of quantitative research is to examine the connection between demographic (gender, age and environmental factors (family, school and media and knowledge and perceptions of students about natural disasters. Bearing in mind the orientation of the research design on determination of character and strength of relationships of demographic and environmental factors with the knowledge and perceptions of students about natural disasters, research has explicative goal. The authors use the method of interviewing high school students to identify demographic and environmental factors associated with the knowledge and perceptions of students about natural disasters. The study included 3,063 students of secondary schools in the city of Belgrade. Results suggest the existence of links between gender, success achieved in school and education of parents and the knowledge of students about natural disasters. The results also indicate that the education of students at school and within family does not affect the knowledge, but affects their perception on natural disasters. Bearing in mind the geographical space of Serbia, the study is based only on the Belgrade region, so the findings can be generalized only to the population of students in this area. Research findings indicate potential ways to influence students to raise level of knowledge about natural disasters to a higher level. Given the evident lack of education about natural disasters in Serbia, the study results can be used for policies of educational programs, which would contribute to improving the safety of youth culture.

  11. Recently Identified Changes to the Demographics of the Current and Future Geoscience Workforce (United States)

    Wilson, C. E.; Keane, C. M.; Houlton, H. R.


    The American Geosciences Institute's (AGI) Geoscience Workforce Program collects and analyzes data pertaining to the changes in the supply, demand, and training of the geoscience workforce. Much of these trends are displayed in detail in AGI's Status of the Geoscience Workforce reports. In May, AGI released the Status of the Geoscience Workforce 2014, which updates these trends since the 2011 edition of this report. These updates highlight areas of change in the education of future geoscientists from K-12 through graduate school, the transition of geoscience graduates into early-career geoscientists, the dynamics of the current geoscience workforce, and the future predictions of the changes in the availability of geoscience jobs. Some examples of these changes include the increase in the number of states that will allow a high school course of earth sciences as a credit for graduation and the increasing importance of two-year college students as a talent pool for the geosciences, with over 25% of geoscience bachelor's graduates attending a two-year college for at least a semester. The continued increase in field camp hinted that these programs are at or reaching capacity. The overall number of faculty and research staff at four-year institutions increased slightly, but the percentages of academics in tenure-track positions continued to slowly decrease since 2009. However, the percentage of female faculty rose in 2013 for all tenure-track positions. Major geoscience industries, such as petroleum and mining, have seen an influx of early-career geoscientists. Demographic trends in the various industries in the geoscience workforce forecasted a shortage of approximately 135,000 geoscientists in the next decade—a decrease from the previously predicted shortage of 150,000 geoscientists. These changes and other changes identified in the Status of the Geoscience Workforce will be addressed in this talk.

    Full Text Available Aim: The aim of this study is to investigate relations between problematic internet use, violence trend and some demographic variables in university students. Methods: The study was conducted with students studying at a state university. The sample consisted of 375 university students as 201 female and 174 male. The data were collected using Demographic Information Form, Internet Addiction Scale (IAS and Violence Proneness Scale (VPS. In the analysis of the data; descriptive statistics student t test, ANOVA, Post hoc Tukey HSD test, pearson correlation analysis and stepwise hierarchical regression analysis were used. Results: The mean age of the students was 21.04+/-1.65 years (age range 18-28 years. It was found that 82.7% of the students in the study group use internet with the purpose of information, and 78.4% of the students use internet for social and entertainment purposes. According to IAS points; 3.7% of the students are problematic internet use, whereas 30.4% show borderline indications in terms of problematic internet use. According to VPS points; 40% of students have high trend of violence and 2.7% of the students have very high trend of violence. A positive relationship was determined between IAS and VPS mean scores (r=0.346, p<0.01. Duration of internet use, violence trend, internet use for social and entertainment purposes and gender are the variables that predict problematic internet use level. Problematic internet use, friend relationships, duration of mother education, gender and duration of internet use are significant predictors of violence trend. Conclusion: The research findings indicate that a significant portion of university students are at risk of problematic internet use and high violence trend. It is believed that the findings obtained in this research will be beneficial in terms of taking necessary measures for groups at risk and of raising awareness among university students.

    Wankiewicz Heidrun


    Full Text Available Ageing society, lack of skilled workforce, changes in work life careers and changes in partner and family models, a shift in societal roles of women and men, young and old, migration flows from rural to urban, multiple residences and new forms of housing and the related spatial impacts are in focus of demographic change. It is obvious that demographic change is not to be managed without gender and equality issues. Spatial planning has a crucial role in facing these challenges as spatial planning laws demand to ensure equal access to housing, services and labour markets and to organize transparent and inclusive decision making procedures. The paper explores key concepts, methods and selected case studies from Europe on gender planning trying to focus on the potential for innovating planning discipline and tackling with demographic change issues in rural areas. Cases from Bavaria and Austria compared to rural regions in Eastern Germany with high female emigration show concrete planning approaches.

  14. Recognizing the expatriate and transnational distance student: A preliminary demographic exploration in the Republic of Korea

    Directory of Open Access Journals (Sweden)

    William H. Stewart


    Full Text Available Descriptions of distance students in the literature are robust. Yet when speaking about students outside of a national context, nuance is lost by the failure to identify the complexity in borderless higher education. The global student body is often too broadly categorized as “international” when in reality, this can be further refined to produce two additional classifications that more appropriately identify and describe a hitherto invisible phenomenon: the expatriate and transnational distance student. Utilizing respondent-driven sampling, student demographic and academic program data were collected using these two operational definitions. The resulting data suggests a potential profile for the expatriate/transnational distance student phenomenon as manifested in South Korea, along with broader demographic and program characteristics. As a nascent phenomenon and introductory inquiry, the research is limited in scope with the intention of a establishing a taxonomy for the distance education community, b a practical method for investigation, and c avenues for further research such as student characteristics, motivation, attrition/retention, etc. Such insight would assist policy/guidelines for universities, their programs, and instructors.

    Full Text Available Introduction: Communication skills are one of the most important skills for health care managers and play an important role in their personal life and future occupation. The present study aimed to evaluate the students’ communication skills as well as its relationship with the students’ demographic characteristics. Method: This descriptive-analytical study was performed on 153 university students majoring in healthcare management in 2014. A self-administered communication skills questionnaire and demographic information form were used to collect the data. Then, the data were analyzed by using SPSS software and appropriate statistical tests including T-Test and ANOVA. Results: The results showed that the students on average got 77.60 out of possible 100 in communication skills. The relationship between communication skills and demographic characteristics, except age, was not statistically significant (p<0.001. The total Cronbach’s alpha was estimated 0.7. There was a statistically significant difference between the communication skills scores of participants in terms of different age groups (p<0.05. Conclusion: The present findings showed a moderate score in communicative skills in students of health care management. Although the communication skill levels in these students were not low, due to the importance of these skills in their future occupation, serious attention is needed to improve their communication skills.

    Selection of medical students at South African (SA) medical schools must promote equitable and fair access to students from all population groups, while ensuring optimal student throughput and success, and training future healthcare practitioners who will fulfil the needs of the local society. In keeping with international practices, a variety of academic and non-academic measures are used to select applicants for medical training programmes in SA medical schools. To provide an overview of the selection procedures used by all eight medical schools in SA, and the student demographics (race and gender) at these medical schools, and to determine to what extent collective practices are achieving the goals of student diversity and inclusivity. A retrospective, quantitative, descriptive study design was used. All eight medical schools in SA provided information regarding selection criteria, selection procedures, and student demographics (race and gender). Descriptive analysis of data was done by calculating frequencies and percentages of the variables measured. Medical schools in SA make use of academic and non-academic criteria in their selection processes. The latter include indices of socioeconomic disadvantage. Most undergraduate medical students in SA are black (38.7%), followed by white (33.0%), coloured (13.4%) and Indian/Asian (13.6%). The majority of students are female (62.2%). The number of black students is still proportionately lower than in the general population, while other groups are overrepresented. Selection policies for undergraduate medical programmes aimed at redress should be continued and further refined, along with the provision of support to ensure student success.

  18. The effects of demographic change on disease transmission and vaccine impact in a household structured population. (United States)

    Geard, Nicholas; Glass, Kathryn; McCaw, James M; McBryde, Emma S; Korb, Kevin B; Keeling, Matt J; McVernon, Jodie


    The demographic structure of populations in both more developed and less developed countries is changing: increases in life expectancy and declining fertility have led to older populations and smaller households. The implications of these demographic changes for the spread and control of infectious diseases are not fully understood. Here we use an individual based model with realistic and dynamic age and household structure to demonstrate the marked effect that demographic change has on disease transmission at the population and household level. The decline in fertility is associated with a decrease in disease incidence and an increase in the age of first infection, even in the absence of vaccination or other control measures. Although large households become rarer as fertility decreases, we show that there is a proportionate increase in incidence of disease in these households as the accumulation of susceptible clusters increases the potential for explosive outbreaks. By modelling vaccination, we provide a direct comparison of the relative importance of demographic change and vaccination on incidence of disease. We highlight the increased risks associated with unvaccinated households in a low fertility setting if vaccine behaviour is correlated with household membership. We suggest that models that do not account for future demographic change, and especially its effect on household structure, may potentially overestimate the impact of vaccination.

    Full Text Available This paper tries to explore the process of urbanization and spatial changes in demographic features in the Monterrey Metropolitan Region (MMR, Mexico. This city is the third largest urban sector in Mexico which has around 4 million population. It is also the industrial and economic capital of the country. The present study found that rapid urbanization in the metropolitan region has a close association with process of industrialization. In population distribution and composition, study found that the metropolitan region had its “demographic transition” during the years seventies and currently the region is taking advantages of demographic bonus cohort, i.e. a higher concentration of population in economic active groups compare to children and old age population. However, this paper indentified a higher imbalance in metropolitan demographic scenario. On the one hand, there is di-populization in the city center region and in other there is a steady increment of population in peri-urban region.

    Aim: To report the student demographics of the inaugural intake into the Bachelor of Medical Imaging and Bachelor of Medical Sonography/Graduate Diploma of Medical Sonography at CQUniversity, Mackay, Australia. Method: Surveys were distributed to students enrolled in the course MEDI11001 Fundamentals of the Imaging Professions; this course is common to both cohorts in Term 1 of the programs. All students enrolled at the time of the survey were present to participate in the survey. Participation was voluntary. Descriptive statistics were developed from responses and thematic analysis applied to open-ended questions. Results: A total of 44 students were enrolled in the programs. The most common place of residence on enrolment was within 40 km of the Mackay campus (16/36.4%); mature age students (30/68.2%); live on campus in the purpose built residences (18/40.9%) and were influenced by the location of the programs in Mackay to enrol (27/61.2%), with the primary justification for this being that the programs were offered close to home. The university website was identified as the primary source of information regarding the programs (15/34.1%) followed by family and friends (11/25%). The programs were first preference for 31 students (70.5%). The majority (23/52.3%) undertakes some type of paid work. Conclusion: Both programs have attracted a diverse student cohort. The majority of students were mature age students from outside of the area local to the Mackay campus of CQUniversity.

    "Broad-scale demographic changes have implications for state and local finance in terms of the composition of the base of revenue sources and their yields. This article examines the effect of such changes on the potential future yield of consumption-based taxes. The effect of household characteristics and composition on the consumption of selected groups of goods subject to ad valorem retail sales taxes is estimated, generating demographic elasticities of consumption. These elasticities are applied to projected demographic changes in eight states through the year 2000. The results show rather wide variation in expected consumption shifts and potential tax bases across the states, with income growth having the greatest effect...."

    Hidefumi eHitokoto


    Full Text Available Today, countries around the world are caught in the tide of change towards Gesellshaft, or individualistic socio-demographic condition. Recent investigations in Japan have suggested negative impacts of change on emotional and motivational aspects of the Japanese self (Norasakkunkit, Uchida, and Toivonen, 2012; Ogihara and Uchida, 2014. Building on previous findings, in Study 1, we measured socio-demographic change towards individualistic societal condition during 1990 to 2010—two decades marked by great economic recession—at the levels of prefecture and city using archival data. In Study 2, we tested whether Japanese adults’ general health, satisfaction with life, self-esteem, and perceived social support were negatively predicted by the change using social survey. Results of hierarchical linear modeling showed small but unique negative effects of the change on several health measures, suggesting that this change had an impact on health, above and beyond individual personality traits and demographics. Additionally, interdependent happiness, the type of cultural happiness grounded in interdependence of the self (Hitokoto and Uchida, 2014, showed an independent positive relationship with all aspects of health examined. Implications for health studies in changing socio-demographic condition are discussed in the context of Japanese society after economic crisis.

A total of 601 dental students participated in the study with a 53% response rate.The written survey covered age, gender, type of school attended, place of residence, parental occupation, level of education, tuition fees payment methods, along with motivations and preferences towards dentistry as a career. The respondents had an average age of 22 years old. Sixty one percent of respondents were female, and the majority had completed secondary education in private and subsidized schools with only 21.5% having finished in public schools. Most of the students covered their tuition fees with parental money (37.1%, followed by any type of loan (27.9%. The majority of students (63.8% had placed dentistry as their first career choice with self-motivation being the most important reason for their decision. This study provides a description of the socio-demographic and economic profile of Chilean dental students and provides insights about career decision issues. It also purposes areas for further research and management by academics for future program development.

    Mioara BORZA


    Full Text Available The social and demographic changes registered in recent years, at European and Romanian level, have produced some effects visible in various reference areas. By this paper, we propose to achieve an empirical analysis meant to emphasize the main socio-economic changes of the last 10 years and their influence on the human society development. Based on the inventory of statistical data referring to the socio-demographic dynamics and using a research methodology based on inductive reasoning, dynamic and dialectics analysis, we will obtain some results of research that indicate: the human development is in positive evolution, even the number of population is decreasing.

  7. The relationship among young adult college students' depression, anxiety, stress, demographics, life satisfaction, and coping styles. (United States)

    Mahmoud, Jihan Saber Raja; Staten, Ruth; Hall, Lynne A; Lennie, Terry A


    Recent research indicates that young adult college students experience increased levels of depression, anxiety, and stress. It is less clear what strategies college health care providers might use to assist students in decreasing these mental health concerns. In this paper, we examine the relative importance of coping style, life satisfaction, and selected demographics in predicting undergraduates' depression, anxiety, and stress. A total of 508 full-time undergraduate students aged 18-24 years completed the study measures and a short demographics information questionnaire. Coping strategies and life satisfaction were assessed using the Brief COPE Inventory and an adapted version of the Brief Students' Multidimensional Life Satisfaction Scale. Depression, anxiety, and stress were measured using the Depression Anxiety and Stress Scale-21 (DASS-21). Multiple regression analyses were used to examine the relative influence of each of the independent variables on depression, anxiety, and stress. Maladaptive coping was the main predictor of depression, anxiety, and stress. Adaptive coping was not a significant predictor of any of the three outcome variables. Reducing maladaptive coping behaviors may have the most positive impact on reducing depression, anxiety, and stress in this population.

  12. Association Between Socio-Demographic Background and Self-Esteem of University Students. (United States)

    Haq, Muhammad Ahsan Ul


    The purpose of this study was to scrutinize self-esteem of university students and explore association of self-esteem with academic achievement, gender and other factors. A sample of 346 students was selected from Punjab University, Lahore Pakistan. Rosenberg self-esteem scale with demographic variables was used for data collection. Besides descriptive statistics, binary logistic regression and t test were used for analysing the data. Significant gender difference was observed, self-esteem was significantly higher in males than females. Logistic regression indicates that age, medium of instruction, family income, student monthly expenditures, GPA and area of residence has direct effect on self-esteem; while number of siblings showed an inverse effect.

  14. Demographic Predictors of Students' Science Participation over the Age of 16: an Australian Case Study (United States)

    Cooper, Grant; Berry, Amanda; Baglin, James


    Using the Longitudinal Surveys of Australian Youth (LSAY) data, this paper aimed to examine if, and to what extent, demographic factors predict students' participation in science over the age of 16 (post-16). While all the students participating in this study are attending Australian schools, the comprehensiveness of these datasets, together with inclusion of studies from around the world provides a useful reference point for an international audience. Over 7000 students are included in the analysis of this paper. Characteristics of focus in this paper include groups who have been identified as being underrepresented in past studies including Indigenous students, those from lower-socio-economic status (SES) backgrounds, sex differences and immigrants. Among the factors tested, Indigenous status was the strongest negative predictor of post-16 science participation. SES was also a relatively strong predictor of post-16 science participation. Compared to students categorised with an Australian-ancestry, first-generation and foreign-background students were more likely to participate in post-16 science. The findings of this study contribute to existing research on debates about equity and trends in science participation.

  16. Modern-Day Demographic Processes in Central Europe and Their Potential Interactions with Climate Change (United States)

    Bański, Jerzy


    The aim of this article is to evaluate the effect of contemporary transformations in the population of Central European countries on climate change, in addition to singling out the primary points of interaction between demographic processes and the climate. In analyzing the interactions between climate and demographics, we can formulate three basic hypotheses regarding the region in question: 1) as a result of current demographic trends in Central Europe, the influence of the region on its climate will probably diminish, 2) the importance of the "climatically displaced" in global migratory movements will increase, and some of those concerned will move to Central Europe, 3) the contribution of the region to global food security will increase. In the last decade most of what comprises the region of Central Europe has reported a decline in population growth and a negative migration balance. As a process, this loss of population may have a positive effect on the environment and the climate. We can expect ongoing climate change to intensify migration processes, particularly from countries outside Europe. Interactions between climate and demographic processes can also be viewed in the context of food security. The global warming most sources foresee for the coming decades is the process most likely to result in spatial polarization of food production in agriculture. Central Europe will then face the challenge of assuring and improving food security, albeit this time on a global scale.

    Binkowska-Bury, Monika; Chmiel-Połeć, Zdzisława; Marć, Małgorzata; Januszewicz, Paweł


    Tobacco smoking is the most known single factor of the highest impact on the number of cancerous deceases. Chemical compound contained in the tobacco smoke have an affect on strong mutagen and carcinogenic actions. Among 400 chemical compound 40 of them have a proven carcinogenic action for human. From the medical point of view the most important are: nicotine- responsible as well as for the pharmacologic tobacco smoking addiction, carbon monoxide, carcinogenic and irritant substances. Regular monitoring of the tobacco smoking among academic students might be used in the actions considering the health risk management. The aim of the study was identifying the relation among selected socio-demographic factors like: age, sex, major, permanent residence, parent's education, material status, medical profile and tobacco smoking among academic students. The research was carried out among 521: science, humanities and medical stationary students. The research was conducted with a usage of the chi-squared evenness test. The research shows that sex and place of residence are the two factors having the most impact on tobacco smoking among academic students. Academic students originated from town or cities as well as men are more often to make a decision on smoking tobacco.

    Parastoo Yarmohammadi


    Full Text Available Abstract Introduction: Fast food consumption has greatly increased with in adolescents in recent years, which is linked with weight gain, poor dietary indexes and insulin resistance. Hence, the purpose of this study was to examine the association between demographic characteristics and fast food consumption with in high school students. Materials & Methods: In this descriptive-analytic study, a sample of 521 high school students  aged 15-18 years were examined in Isfahan city, who were selected via multistage sampling method. The study data were collected using a questionnaire completed by the students. The present study probed to assess such items as frequency of fast food consumption, demographic characteristics, hours of television viewing, as well as high school students' knowledge and attitude. The collected data were analyzed using descriptive and inferential statistics. Result: Frequent intake of fast food (&ge1 time/week was reported 15.5% within females and 15.3% within males. A significant relationship was detected between parents’ high level of education and high income of the family with the fast food consumption. The predominate reasons for fast food consumption were stated as “enjoying tastes”, “eating at any place”,” inexpensive and economic”. Conclusion: The findings revealed that fast food consumption increased in families with high income and high education level, though these families needed to be educated on the harmful effects of fast food and how to choose the healthy foods. Therefore, some interventions may be regarded beneficial in order to reduce the exposure to the fast food and promote knowledge, attitude, and behavior change in regard with reducing consumption of fast food.

    Cardinal, Bradley J; Lee, Jong-Young; Kim, Young-Ho; Lee, Hyo; Li, Kin-Kit; Si, Qi


    Examine behavioral, demographic, psychosocial, and sociocultural concomitants of the stages of change for physical activity behavior among college students in South Korea (n = 221) and the United States (n = 166). Measures obtained in this cross-sectional study included age; body mass index; nationality; gender; exercise behavior; processes of change; decisional balance; self-efficacy; stage of change; and predisposing, reinforcing, and enabling factors. The amount of variance explained for stage of change by the transtheoretical model constructs (i.e., decisional balance, processes of change, self-efficacy) ranged from 11% to 29% (all p behavior (OR = 1.04; p behavioral processes of change (OR = 1.12; p change. In terms of physical activity behavior, South Korean women were more likely than South Korean men to be in the early stages, whereas American men were slightly more likely to be in the early stages than American women when all the concomitants were accounted for. Among the psychosocial stage of change concomitants, only the behavioral processes of change were found to be important.

  20. Future scenarios of land change based on empirical data and demographic trends (United States)

    Sleeter, Benjamin M.; Wilson, Tamara; Sharygin, Ethan; Sherba, Jason


    Changes in land use and land cover (LULC) have important and fundamental interactions with the global climate system. Top-down global scale projections of land use change have been an important component of climate change research; however, their utility at local to regional scales is often limited. The goal of this study was to develop an approach for projecting changes in LULC based on land use histories and demographic trends. We developed a set of stochastic, empirical-based projections of LULC change for the state of California, for the period 2001–2100. Land use histories and demographic trends were used to project a “business-as-usual” (BAU) scenario and three population growth scenarios. For the BAU scenario, we projected developed lands would more than double by 2100. When combined with cultivated areas, we projected a 28% increase in anthropogenic land use by 2100. As a result, natural lands were projected to decline at a rate of 139 km2 yr−1; grasslands experienced the largest net decline, followed by shrublands and forests. The amount of cultivated land was projected to decline by approximately 10%; however, the relatively modest change masked large shifts between annual and perennial crop types. Under the three population scenarios, developed lands were projected to increase 40–90% by 2100. Our results suggest that when compared to the BAU projection, scenarios based on demographic trends may underestimate future changes in LULC. Furthermore, regardless of scenario, the spatial pattern of LULC change was likely to have the greatest negative impacts on rangeland ecosystems.

  5. [Demographic and epidemiologic changes in Colombia during the 20th century: facts and explanations]. (United States)

    Carmona-Fonseca, Jaime


    Research, education, organization and administration activities in health need an updated panoramic view of demographic and epidemiologic changes and tendencies. To describe the main changes in demography and epidemiology during the 20th century in Colombia and to comment on the causative models used by some authors. A descriptive and longitudinal study. Second hand information from various sources was used. The final section of the review includes a discussion on the interpretation of data given by the original authors. In 1905-2005, population increased from 4,737,588 inhabitants to 48,864,013. The age distribution of the population showed dramatic changes: the true pyramid, as seen in 1951, changed into a distorted figure (no apparent differences between 0 and 14 years of age). Both children and youngsters lost representation on age structure, while adult and older individuals gain representation. During 1905-1938, the birth rate was 43% and by the end of 2005 it will be 22%. Mortality dropped a 75%, falling from 23% in 1905-1912 to 6% in 1885-1993, but it rose a 33% after 1993, and will reach 8.3% in 2010. In 1938, the urban population was 31% and in 2002, 72%. Mortality discriminated by cause changed in a significant manner during the second half of the 20th century. Infectious-parasitic and perinatal diseases, the main cause of death by the end of the 1960-1969 decade, lost importance on behalf of degenerative diseases, accidents and homicides which are now the most frequent. Conclusions. Our present population density is relatively low. The demographic change has been profound but the velocity has been more important. The aging of population has serious implications for the country. These notable modifications in Colombian families raise challenges in all social fields. The demographic and epidemiological changes (structure and level of morbimortality) require a serious analysis, and easy explanations do not have to be accepted without repairs.

  6. The impact of socio-demographic and religious factors upon sexual behavior among Ugandan university students. (United States)

    Agardh, Anette; Tumwine, Gilbert; Östergren, Per-Olof


    More knowledge is needed about structural factors in society that affect risky sexual behaviors. Educational institutions such as universities provide an opportune arena for interventions among young people. The aim of this study was to investigate the relationship between sociodemographic and religious factors and their impact on sexual behavior among university students in Uganda. In 2005, 980 university students (response rate 80%) were assessed by a self-administered questionnaire. Validated instruments were used to assess socio-demographic and religious factors and sexual behavior. Logistic regression analyses were applied. Our findings indicated that 37% of the male and 49% of the female students had not previously had sex. Of those with sexual experience, 46% of the males and 23% of the females had had three or more sexual partners, and 32% of the males and 38% of the females did not consistently use condoms. For those who rated religion as less important in their family, the probability of early sexual activity and having had a high number of lifetime partners increased by a statistically significant amount (OR = 1.7; 95% CI: 1.2-2.4 and OR = 1.6; 95% CI: 1.1-2.3, respectively). However, the role of religion seemed to have no impact on condom use. Being of Protestant faith interacted with gender: among those who had debuted sexually, Protestant female students were more likely to have had three or more lifetime partners; the opposite was true for Protestant male students. Religion emerged as an important determinant of sexual behavior among Ugandan university students. Our findings correlate with the increasing number of conservative religious injunctions against premarital sex directed at young people in many countries with a high burden. of HIV/AIDS. Such influence of religion must be taken into account in order to gain a deeper understanding of the forces that shape sexual behavior in Uganda.

  7. Socio-demographic and dietary factors associated with obesity among female university students in Jordan. (United States)

    Musaiger, Abdulrahman O; Hammad, Shatha S; Tayyem, Reema F; Qatatsheh, Ala A


    This study aimed to explore the socio-demographic and dietary factors that may be associated with obesity among female university students in Jordan. A cross-sectional survey was carried out among 406 female students recruited from two universities in Jordan. Data were collected through self-reporting, using a previously validated questionnaire. Weight and height were measured and body mass index was calculated to determine the weight status of the participants. High educational level of mothers [odds ratio (OR)=1.25] and monthly pocket money of more than 200 Jordanian Dinars (OR=1.67) were found to be risk factors for obesity, whereas a sibling ranking of more than six was a protective factor (OR=0.31). Those who were eating from the university cafeteria had double the risk for obesity (OR=2.41) than those who did not. Regular eating of meals and snacking between meals were found to be protective factors (OR ranged from 0.42 to 0.79). Regular consumption of milk products, fruit, canned fruit juices, bakery products and legumes were found to be protective factors. In contrast, the regular consumption of potato chips (OR=1.35), chicken (OR=1.51), and fish (OR=1.45) were found to be risk factors for obesity. Using a chi-square test, none of the factors studied showed significant association with obesity. A program to promote healthy eating among university students in Jordan should consider the local socio-demographic and food behavior factors that could be related to obesity to ensure the effectiveness of such a program.

  10. Contrasted demographic responses facing future climate change in Southern Ocean seabirds. (United States)

    Barbraud, Christophe; Rivalan, Philippe; Inchausti, Pablo; Nevoux, Marie; Rolland, Virginie; Weimerskirch, Henri


    1. Recent climate change has affected a wide range of species, but predicting population responses to projected climate change using population dynamics theory and models remains challenging, and very few attempts have been made. The Southern Ocean sea surface temperature and sea ice extent are projected to warm and shrink as concentrations of atmospheric greenhouse gases increase, and several top predator species are affected by fluctuations in these oceanographic variables. 2. We compared and projected the population responses of three seabird species living in sub-tropical, sub-Antarctic and Antarctic biomes to predicted climate change over the next 50 years. Using stochastic population models we combined long-term demographic datasets and projections of sea surface temperature and sea ice extent for three different IPCC emission scenarios (from most to least severe: A1B, A2, B1) from general circulation models of Earth's climate. 3. We found that climate mostly affected the probability to breed successfully, and in one case adult survival. Interestingly, frequent nonlinear relationships in demographic responses to climate were detected. Models forced by future predicted climatic change provided contrasted population responses depending on the species considered. The northernmost distributed species was predicted to be little affected by a future warming of the Southern Ocean, whereas steep declines were projected for the more southerly distributed species due to sea surface temperature warming and decrease in sea ice extent. For the most southerly distributed species, the A1B and B1 emission scenarios were respectively the most and less damaging. For the two other species, population responses were similar for all emission scenarios. 4. This is among the first attempts to study the demographic responses for several populations with contrasted environmental conditions, which illustrates that investigating the effects of climate change on core population dynamics

  11. Bullying Perpetration, Victimization, and Demographic Differences in College Students: A Review of the Literature. (United States)

    Lund, Emily M; Ross, Scott W


    Although bullying has been widely recognized as a serious issue in elementary and secondary school and in the workplace, little is known about the prevalence of bullying in postsecondary education. We conducted a comprehensive search of the peer-reviewed literature and found 14 studies that reported the prevalence of bullying perpetration, victimization, or both in college or university students. Prevalence estimates varied widely been studies, but on average about 20-25% of students reported noncyberbullying victimization during college and 10-15% reported cyberbullying victimization. Similarly, approximately 20% of students on average reported perpetrating noncyberbullying during college, with about 5% reporting cyber perpetration. Men were more likely to report perpetration, but no consistent gender differences in victimization were found. Few studies reported prevalence by sexual orientation or race/ethnicity, and none reported prevalence by disability status. Overall, these results indicate that bullying continues to be prevalent in postsecondary education, but more research needs to be conducted, particularly that which uses multiuniversity samples and examines demographic differences in prevalence rates. © The Author(s) 2016.

  12. Attitudes Toward LGBT Patients Among Students in the Health Professions: Influence of Demographics and Discipline. (United States)

    Wilson, Christina K; West, Lindsey; Stepleman, Lara; Villarosa, Margo; Ange, Brittany; Decker, Matthew; Waller, Jennifer L


    Health providers' personal and professional experiences may predict attitudes toward lesbian, gay, bisexual, and transgender (LGBT) individuals and can therefore serve as key targets for health professions training aimed at decreasing barriers to high-quality patient care. This study explored the relationship between professional, demographic, and training characteristics and health professions student attitudes toward LGBT patients. Students from a health sciences university and applied mental health programs in Georgia (N=475) completed a survey that included a modified version of the Attitudes Toward LGBT Patients Scale (ATLPS). Profession, sexual orientation, current financial status, religion, religiosity, spirituality, and self-reported familiarity with various religious perspectives on sex were associated with ATLPS scores. However, religiosity and self-reported familiarity with various religious perspectives on sex were the only significant predictors of ATLPS scores when these variables were included in one general linear model. Health professions students with higher levels of religiosity and lower levels of self-reported familiarity with various religious perspectives on sex reported less positive attitudes toward LGBT individuals. Results suggest that personal factors may be important to address in interprofessional curriculum related to LGBT patient care. Self-report biases and other factors may limit the accuracy and generalizability of the findings.

  13. Decline, Adaptation or Transformation:New Perspectives on Demographic Change in Resource Peripheries in Australia and Sweden

    Directory of Open Access Journals (Sweden)

    Dean B. Carson


    Full Text Available Many sparsely populated resource peripheries in developed countries are perceived to suffer from periods of demographic decline due to loss of employment opportunities and services, youth out-migration and population ageing. While these trends tend to apply at broad regional scales and for particular time periods, diverse patterns of demographic change may be apparent if different spatial, temporal and social scales of analysis are taken into consideration. Comparing the experiences of two case study regions in northern Sweden and inland South Australia, this paper proposes an alternative conceptual framework to the “discourse of decline”, which could be used to examine the nuances of demographic change within resource peripheries. The framework includes spatial scale considerations that contrast broader regional demographic patterns with the experiences of sub-regions and individual settlements. It also includes temporal scale aspects, examining demographic change over different time periods to understand the pace, duration and frequency of population growth and decline. The framework finally includes social unit considerations, emphasising that demographic change affects different social groups in different ways. The results of the case studies suggest that considering demographic change as adaptation or transformation rather than decline may be more useful for identifying new – and qualitatively different – demographic pathways that emerge over time.

    Abdolghani Abdollahimohammad


    Full Text Available Purpose: The goal of the current study was to identify associations between the learning style of nursing students and their cultural values and demographic characteristics. Methods: A non-probability purposive sampling method was used to gather data from two populations. All 156 participants were female, Muslim, and full-time degree students. Data were collected from April to June 2010 using two reliable and validated questionnaires: the Learning Style Scales and the Values Survey Module 2008 (VSM 08. A simple linear regression was run for each predictor before conducting multiple linear regression analysis. The forward selection method was used for variable selection. P-values ≤0.05 and ≤0.1 were considered to indicate significance and marginal significance, respectively. Moreover, multi-group confirmatory factor analysis was performed to determine the invariance of the Farsi and English versions of the VSM 08. Results: The perceptive learning style was found to have a significant negative relationship with the power distance and monumentalism indices of the VSM 08. Moreover, a significant negative association was observed between the solitary learning style and the power distance index. However, no significant association was found between the analytic, competitive, and imaginative learning styles and cultural values (P>0.05. Likewise, no significant associations were observed between learning style, including the perceptive, solitary, analytic, competitive, and imaginative learning styles, and year of study or age (P>0.05. Conclusion: Students who reported low values on the power distance and monumentalism indices are more likely to prefer perceptive and solitary learning styles. Within each group of students in our study sample from the same school the year of study and age did not show any significant associations with learning style.

    The goal of the current study was to identify associations between the learning style of nursing students and their cultural values and demographic characteristics. A non-probability purposive sampling method was used to gather data from two populations. All 156 participants were female, Muslim, and full-time degree students. Data were collected from April to June 2010 using two reliable and validated questionnaires: the Learning Style Scales and the Values Survey Module 2008 (VSM 08). A simple linear regression was run for each predictor before conducting multiple linear regression analysis. The forward selection method was used for variable selection. P-values ≤0.05 and ≤0.1 were considered to indicate significance and marginal significance, respectively. Moreover, multi-group confirmatory factor analysis was performed to determine the invariance of the Farsi and English versions of the VSM 08. The perceptive learning style was found to have a significant negative relationship with the power distance and monumentalism indices of the VSM 08. Moreover, a significant negative association was observed between the solitary learning style and the power distance index. However, no significant association was found between the analytic, competitive, and imaginative learning styles and cultural values (P>0.05). Likewise, no significant associations were observed between learning style, including the perceptive, solitary, analytic, competitive, and imaginative learning styles, and year of study or age (P>0.05). Students who reported low values on the power distance and monumentalism indices are more likely to prefer perceptive and solitary learning styles. Within each group of students in our study sample from the same school the year of study and age did not show any significant associations with learning style.

  17. Climate change underlies global demographic, genetic, and cultural transitions in pre-Columbian southern Peru. (United States)

    Fehren-Schmitz, Lars; Haak, Wolfgang; Mächtle, Bertil; Masch, Florian; Llamas, Bastien; Cagigao, Elsa Tomasto; Sossna, Volker; Schittek, Karsten; Isla Cuadrado, Johny; Eitel, Bernhard; Reindel, Markus


    Several archaeological studies in the Central Andes have pointed at the temporal coincidence of climatic fluctuations (both long- and short-term) and episodes of cultural transition and changes of socioeconomic structures throughout the pre-Columbian period. Although most scholars explain the connection between environmental and cultural changes by the impact of climatic alterations on the capacities of the ecosystems inhabited by pre-Columbian cultures, direct evidence for assumed demographic consequences is missing so far. In this study, we address directly the impact of climatic changes on the spatial population dynamics of the Central Andes. We use a large dataset of pre-Columbian mitochondrial DNA sequences from the northern Rio Grande de Nasca drainage (RGND) in southern Peru, dating from ∼840 BC to 1450 AD. Alternative demographic scenarios are tested using Bayesian serial coalescent simulations in an approximate Bayesian computational framework. Our results indicate migrations from the lower coastal valleys of southern Peru into the Andean highlands coincident with increasing climate variability at the end of the Nasca culture at ∼640 AD. We also find support for a back-migration from the highlands to the coast coincident with droughts in the southeastern Andean highlands and improvement of climatic conditions on the coast after the decline of the Wari and Tiwanaku empires (∼1200 AD), leading to a genetic homogenization in the RGND and probably southern Peru as a whole.

  18. Demographic Change, Economic Conditions, and the Murder Rate: The Case of the Colombia, 1990 to 2013

    Full Text Available Recent changes in the Colombian homicides rate not consider the change in the age distribution, inflation and unemployment that can explain how misery affects homicides in the long run. Therefore, from a relevant time period for Colombia can be analyzed if recent demographic transition given by a higher percentage of young population is a robust predictor of observed changes in the homicide rate along with a corresponding measure of misery given for the sum between unemployment rates and local inflation. This helps explain the long-term relationship between the age distribution in Colombia and rising homicide rates in the 90s along with the decrease in the latter part of the 2000s. It was found that there is a relationship between age and crime, as suggested by the classical literature and there is a long-term relationship between the homicides, misery and youth population density.

  19. Understanding Students' Transition to High School: Demographic Variation and the Role of Supportive Relationships. (United States)

    Benner, Aprile D; Boyle, Alaina E; Bakhtiari, Farin


    The transition to high school is disruptive for many adolescents, yet little is known about the supportive relational processes that might attenuate the challenges students face as they move from middle to high school, particularly for students from more diverse backgrounds. Identifying potential buffers that protect youth across this critical educational transition is important for informing more effective support services for youth. In this study, we investigated how personal characteristics (gender, nativity, parent education level) and changes in support from family, friends, and school influenced changes in socioemotional adjustment and academic outcomes across the transition from middle to high school. The data were drawn from 252 students (50% females, 85% Latina/o). The results revealed declines in students' grades and increases in depressive symptoms and feelings of loneliness across the high school transition, with key variation by student nativity and gender. Additionally, stable/increasing friend support and school belonging were both linked to less socioemotional disruptions as students moved from middle to high school. Increasing/stable school belonging was also linked to increases in school engagement across the high school transition. These findings suggest that when high school transitions disrupt supportive relationships with important others in adolescents' lives, adolescents' socioemotional well-being and, to a lesser extent, their academic engagement are also compromised. Thus, in designing transition support activities, particularly for schools serving more low-income and race/ethnic minority youth, such efforts should strive to acclimate new high school students by providing inclusive, caring environments and positive connections with educators and peers.

  20. Potential (mis)match?: Marriage Markets amidst Socio-Demographic Change in India, 2005–2050 (United States)

    Kashyap, Ridhi; Esteve, Albert; García-Román, Joan


    We explore the impact of socio-demographic change on marriage patterns in India by examining the hypothetical consequences of applying three sets of marriage pairing propensities – contemporary patterns by age, by age and education, and changing propensities that allow for greater educational homogamy and reduced educational asymmetries – to future population projections. Future population prospects for India indicate three trends that will impact marriage patterns: i) female-deficit in sex ratios at birth; ii) declining birth cohort size; iii) female educational expansion. Existing literature posits declining marriage rates for men arising from skewed sex ratios at birth (SRB) in India’s population. In addition to skewed SRBs, India’s population will experience female educational expansion in the coming decades. Female educational expansion and its impact on marriage patterns must be jointly considered with demographic changes, given educational differentials and asymmetries in union formation that exist in India, as across much of the world. We systematize contemporary pairing propensities using data from the 2005–2006 Indian National Family Health Survey and the 2004 Socio-Economic Survey and apply these and the third set of changing propensities to IIASA/VID multi-state population projections by educational attainment using an iterative longitudinal projection procedure. If today’s age patterns of marriage are viewed against age-sex population composition until 2050, men experience declining marriage prevalence. However, when education is included, women, particularly those with higher education experience a more salient rise in non-marriage. Significant changes in pairing patterns towards greater levels of educational homogamy and gender symmetry can counteract a marked rise in non-marriage. PMID:25604846

    Full Text Available Objectives: (1 To examine trends in level of student loan indebtedness for groups of pharmacists that were first licensed between 1980 and 2006; (2 To examine if demographic variables are associated with level of student loan indebtedness; (3 To examine the association between student loan debt and choice of practice setting while controlling for demographic variables. Methods: Data for this study were collected from a national random sample of 3,000 pharmacists using a self administered survey. Descriptive statistics were used to examine trends in level of indebtedness. The relationships between level of indebtedness, demographic variables and practice setting choice were examined using Chi-square statistics. Multinomial logistic regression was used to determine the independent association of student loan debt and choice of practice setting while controlling for demographic variables. Results: The proportion of licensed pharmacists reporting student loan debt after graduation, and the mean amount of debt incurred increased between 1980 and 2006. Non-white pharmacists incurred debt at a higher proportion compared to white, and they also incurred significantly higher levels of debt. A lower level of indebtedness was associated with choosing independent practice over chain practice. Conclusions: Student loan indebtedness has been increasing over time, especially for non-white pharmacy students. Future research should be done to examine other factors that might influence student debt load, work contributions and choice of practice settings. The affordability of pharmacy education for students of color and how salaries may or may not help off-set these costs also should be examined closely.   Type: Original Research

  2. A population-based longitudinal study on the implication of demographic changes on blood donation and transfusion demand. (United States)

    Greinacher, Andreas; Weitmann, Kerstin; Schönborn, Linda; Alpen, Ulf; Gloger, Doris; Stangenberg, Wolfgang; Stüpmann, Kerstin; Greger, Nico; Kiefel, Volker; Hoffmann, Wolfgang


    Transfusion safety includes the risk of transmission of pathogens, appropriate transfusion thresholds, and sufficient blood supply. All industrialized countries experience major ongoing demographic changes resulting from low birth rates and aging of the baby boom generation. Little evidence exists about whether future blood supply and demand correlate with these demographic changes. The ≥50% decline in birth rate in the eastern part of Germany after 1990 facilitates systematic study of the effects of pronounced demographic changes on blood donation and demand. In this prospective, 10-year longitudinal study, we enrolled all whole blood donors and all patients receiving red blood cell transfusions in the state of Mecklenburg-West Pomerania. We compared projections made in 2005 based on the projected demographic changes with: (1) number and age distribution of blood donors and transfusion recipients in 2015 and (2) blood demand within specific age and patient groups. Blood donation rates closely followed the demographic changes, showing a decrease of -18% (vs projected -23%). In contrast, 2015 transfusion rates were -21.3% lower than projected. We conclude that although changes in demography are highly predictive for the blood supply, transfusion demand is strongly influenced by changes in medical practice. Given ongoing pronounced demographic change, regular monitoring of the donor/recipient age distributions and associated impact on blood demand/supply relationships is required to allow strategic planning to prevent blood shortages or overproduction.

  3. Rural AIDS Diagnoses in Florida: Changing Demographics and Factors Associated With Survival (United States)

    Trepka, Mary Jo; Niyonsenga, Theophile; Maddox, Lorene M.; Lieb, Spencer


    Purpose To compare demographic characteristics and predictors of survival of rural residents diagnosed with acquired immunodeficiency syndrome (AIDS) with those of urban residents. Methods Florida surveillance data for people diagnosed with AIDS during 1993–2007 were merged with 2000 Census data using ZIP code tabulation areas (ZCTA). Rural status was classified based on the ZCTA’s rural-urban commuting area classification. Survival rates were compared between rural and urban areas using survival curves and Cox proportional hazards models controlling for demographic, clinical, and area-level socioeconomic and health care access factors. Findings Of the 73,590 people diagnosed with AIDS, 1,991 (2.7%) resided in rural areas. People in the most recent rural cohorts were more likely than those in earlier cohorts to be female, non-Hispanic black, older, and have a reported transmission mode of heterosexual sex. There were no statistically significant differences in the 3-, 5-, or 10-year survival rates between rural and urban residents. Older age at the time of diagnosis, diagnosis during the 1993–1995 period, other/unknown transmission mode, and lower CD4 count/percent categories were associated with lower survival in both rural and urban areas. In urban areas only, being non-Hispanic black or Hispanic, being US born, more poverty, less community social support, and lower physician density were also associated with lower survival. Conclusions In rural Florida, the demographic characteristics of people diagnosed with AIDS have been changing, which may necessitate modifications in the delivery of AIDS-related services. Rural residents diagnosed with AIDS did not have a significant survival disadvantage relative to urban residents. PMID:23802929

  4. Adjustment, social sectors, and demographic change in Sub-Saharan Africa. (United States)

    Ekouevi, K; Adepoju, A


    This discussion concludes that the economic crises of the 1980s resulted in a halt to the social and economic development of sub-Saharan Africa. Employment, health, and education sectors all deteriorated under structural adjustment programs (SAPs) and poor economic performance. SAPs are considered inadequate solutions to long-term problems. Economic crises were found to affect countries differently in their demographic impact. Delayed demographic transition occurred both through economic development as a prerequisite and as a result of poor economic development. Case studies of each country are considered the appropriate geographic unit of analysis of demographic change rather than regional or comparative studies. The economic crises in sub-Saharan Africa occurred due to both external (commodity prices, high real interest rates, and decreasing net capital flows) and internal distortions (strategies of development such as import substitution, neglect of the agricultural sector, and government control of prices and trade). The unfavorable external context reduced export prices and earnings while increasing the costs of imports. Internal controls were detrimental to farmers. During the 1970s and 1980s African countries experienced declines in both the volume and value of exports, increases in import volume, and imbalances in the balance of payments. Large domestic borrowing and foreign borrowing was done by governments, which was at the expense of the private sector. Economic management and corruption were rampant. SAPs restrained demand, reduced public expenditures, adjusted exchange rates, contracted the size of the public sector, liberalized trade, deregulated the interest rate, stimulated domestic production, and used market forces for balancing optimum allocation of resources. SAPs were the fix for trade imbalances and government debt. Development was slowed or stopped. During 1980-87 spending on health care, education, and infrastructure was drastically reduced

  5. Changes in food neophobia and dietary habits of international students. (United States)

    Edwards, J S A; Hartwell, H L; Brown, L


    International study is becoming more prevalent, yet aspects such as food neophobia often militate against visiting students consuming a nutritionally balanced diet. The present study aimed to evaluate the extent to which international post-graduate students experience food neophobia, how this might vary by nationality and other demographic characteristics, and how acculturation might manifest itself in students' dietary behaviour. International students (n = 228) attending a Masters course were invited to complete a validated food neophobia and dietary habits questionnaire during their first week at university. The questionnaire was subsequently re-administered to the same students approximately 4 and 8 months later. In total, 226 usable responses were analysed (124, 58 and 44, respectively) for the first, second and final data collection. Perhaps surprisingly, the overall food neophobia scores increased from an mean (SD) initial value of 27.95 (16.95) to 33.67 (33.67) after 3 months, although, when comparing European and Asian students, only the former were significantly different (P Asian and European students reported small but not significant changes in their eating habits, although, after 3 months, significantly (P = students' perceived healthiness of their diets either by nationality or over time. Understanding the complexities of food neophobia, other aspects of dietary change and at what point these changes might take place in the acculturation process when students arrive in the UK needs to be fully understood if a climate for positive learning is to be established.

  6. The role of demographics in students' selection of higher education institutions

    M. Wiese


    Full Text Available Purpose: To investigate the choice factors students consider when selecting a higher education institution, with a focus on the differences between gender and language groups. Problem investigated: The educational landscape has seen several changes, such as stronger competition between institutions for both student enrolments and government funding. These market challenges have led to an interest in students' institution selection processes as it has implications for the way higher education institutions (HEIs manage their marketing and recruitment strategies. The research objective of this study was to identify the most important choice factors of prospective South African students. It also aimed to determine if any gender and language differences exist with regard to students' institution selection processes. Methodology: A convenience sample of 1 241 respondents was drawn, representing six South African universities. A self-administrated questionnaire was used to collect the data. Questions from the ASQ (Admitted Student Questionnaire and CIRP (The Cooperative Institutional Research Programme were used and adapted to the South African context after pilot testing. Hypotheses were analysed using the multivariate analysis of variance (MANOVA test with Wilks' lambda as the test statistic. Findings/Implications: Irrespective of gender or language, the most important choice factor for respondents was the quality of teaching at HEIs. The findings showed that males and females differ according to the selection of certain choice factors which suggest that HEIs can consider recruitment strategies for each gender group. Significant differences between the language groups were found for 17 of the 23 choice factors, signalling that different language groups make decisions based on different choice factors. African language-speaking students have, amongst other, indicated that the multiculturalism of the institution is a very important choice factor for

  11. Knowledge Management Impacts on Organizational Proficiency in a Changing Demographic Nuclear Industry

    International Nuclear Information System (INIS)

    Heler, D.; Marco, J. A.


    Full text: The US nuclear energy industry has focused on workforce development and planning efforts over the past decade in anticipation of a large number of retirements taking place. Efforts by the US nuclear industry to replace retiring workers with younger staff to close the knowledge gap and improve organizational proficiency have started. This is resulting in a bimodal workforce distribution, which means that the industry has two workforce peaks. The 2015 Nuclear Energy Institute (NEI) Workforce Pipeline Survey results illustrate a significant number of experienced and young professionals, with fewer employees in the mid-career age group. This workforce distribution can pose a challenge for US nuclear industry to ensure it has effectively implemented knowledge management elements (People, Process, and Technology) to improve organizational proficiency and maintain critical skill sets. This technical brief will examine how one US nuclear plant performance dropped, which in part was a result of a significant demographic shift in their organizations. In addition, the paper will explore the challenge organizations may have as they undergo demographic changes without proper knowledge management programmes in place. (author

    Antonio Carroccio


    Full Text Available Background: Non-Celiac Wheat Sensitivity (NCWS has recently been included among the gluten-related disorders. As no biomarkers of this disease exist, its frequency has been estimated based on self-reported symptoms, but to date no data are available about self-reported NCWS in teenagers. Aim: To explore the prevalence of self-reported NCWS in a group of high school students and to study their demographic and clinical characteristics. Methods: The study was performed between April 2015 and January 2016 in two high schools of a coastal town in the south of Sicily (Italy. A total of 555 students (mean age 17 years, 191 male, 364 female completed a modified validated questionnaire for self-reported NCWS. The subjects who self-reported NCWS were then compared with all the others. Results: Seven individuals (1.26% had an established diagnosis of CD. The prevalence of self-reported NCWS was 12.2%, and 2.9% were following a gluten-free diet (GFD. Only 15 out of 68 (23% NCWS self-reporters had consulted a doctor for this problem and only nine (14% had undergone serological tests for celiac disease. The NCWS self-reporters very often had IBS symptoms (44%. Conclusions: Self-reported NCWS was found to be common in teenagers, with a frequency of 12.2%; the frequency of GFD use was 2.9%, which was much higher than the percentage of known CD in the same population (1.26%. A greater awareness of the possible implications on the part of the subjects involved, and a more thorough medical approach to the study of self-reported wheat-induced symptoms are required.

  15. Simulating Residential Demand in Singapore through Five Decades of Demographic Change (United States)

    Davis, N. R.; Fernández, J.


    Singapore's rapid and well-documented development over the last half-century provides an ideal case for studying urban metabolism. Extensive data [1, 2] facilitate the modeling of historical dynamics of population and resource consumption. This paper presents an agent-based population model that simulates key demographic factors - number, size, and relative income of households - through fifty years of development in Singapore. This is the first step in a broader study linking demographic factors to residential demand for urban land, materials, water, and energy. Previous studies of the resource demands of housing stock have accounted for demographics by modifying the important population driver with a single, aggregated "lifestyle" term [3, 4]. However, demographic changes that result from development can influence the nature of the residential sector, and warrant a closer look. Increasing levels of education and affluence coupled with decreasing birth rates have yielded an aging population and changing family structures in Singapore [5]. These factors all contribute to an increasingly resource-intense residential sector. Singaporeans' elevated per capita income and life expectancy have created demand for larger household area, which means a growing percentage of available land must be dedicated to residential use [6]. While the majority of Singapore's housing is public - a strategy designed to maximize land use efficiency - residents are increasingly seeking private alternatives [7]. In the private sector, lower density housing puts even greater pressure on the finite supply of undeveloped land. Agent-based modeling is used to study the selected aspects of demography. The population is disaggregated into historical time-series distributions of age, family size, education, and income. We propose a simplified methodology correlating average education level with birth rate, and income to categorize households and establish housing unit demand. Aggregated lifestyle

  16. A demographic approach to study effects of climate change in desert plants (United States)

    Salguero-Gómez, Roberto; Siewert, Wolfgang; Casper, Brenda B.; Tielbörger, Katja


    Desert species respond strongly to infrequent, intense pulses of precipitation. Consequently, indigenous flora has developed a rich repertoire of life-history strategies to deal with fluctuations in resource availability. Examinations of how future climate change will affect the biota often forecast negative impacts, but these—usually correlative—approaches overlook precipitation variation because they are based on averages. Here, we provide an overview of how variable precipitation affects perennial and annual desert plants, and then implement an innovative, mechanistic approach to examine the effects of precipitation on populations of two desert plant species. This approach couples robust climatic projections, including variable precipitation, with stochastic, stage-structured models constructed from long-term demographic datasets of the short-lived Cryptantha flava in the Colorado Plateau Desert (USA) and the annual Carrichtera annua in the Negev Desert (Israel). Our results highlight these populations' potential to buffer future stochastic precipitation. Population growth rates in both species increased under future conditions: wetter, longer growing seasons for Cryptantha and drier years for Carrichtera. We determined that such changes are primarily due to survival and size changes for Cryptantha and the role of seed bank for Carrichtera. Our work suggests that desert plants, and thus the resources they provide, might be more resilient to climate change than previously thought. PMID:23045708

  17. Personal and socio-demographic characteristics as correlates of value orientations and interests of students in Vojvodina

    Directory of Open Access Journals (Sweden)

    Gajić Olivera


    Full Text Available Social transition and changes in the cultural context inevitably impose the need of redefining the value systems which are particularly reflected through the differences of the multicultural framework such as, for example, Vojvodina. The paper presents the results of a theoretical and empirical study of students’ interests and value orientations. The results are viewed through the prism of influence of respondents’ individual and socio-demographic characteristics. Non-experimental causal method was used to study the correlation between variable groups. Interviewing was the research technique. The instrument for data collection was the questionnaire constructed for the purposes of the research. The study was conducted during the school year 2007/08 in Novi Sad, on the sample of 480 respondents - students of the University of Novi Sad, aged 19 to 24. Gender was studied in the group of personal (individual, constitutional features and it proved out to be a significant correlate of certain interests: sport, cultural and creative, as well as relational values (nourishing harmonious family relations, marriage, parenthood, partnership, feeling of belonging et al.. In the group of socio-demographic characteristics (structural forms of the family, financial status, social background, socio-cultural space: rural-urban it was established that social background correlates with interest in sport activities, educational and artistic interests, while variables social background and place of residence correlate with social life and social relations as dominant value orientations. Research results provide pedagogical implications for educational work with youth aimed at developing the values connected with constructive activities and encouragement of proactive orientation with respect to one’s own surroundings and existence, as well as the guidelines for introducing new contents into the existing curricula, in accordance with the expressed values and

  19. Influence of demographic changes on the impact of vaccination against varicella and herpes zoster in Germany - a mathematical modelling study. (United States)

    Horn, Johannes; Damm, Oliver; Greiner, Wolfgang; Hengel, Hartmut; Kretzschmar, Mirjam E; Siedler, Anette; Ultsch, Bernhard; Weidemann, Felix; Wichmann, Ole; Karch, André; Mikolajczyk, Rafael T


    Epidemiological studies suggest that reduced exposure to varicella might lead to an increased risk for herpes zoster (HZ). Reduction of exposure to varicella is a consequence of varicella vaccination but also of demographic changes. We analyzed how the combination of vaccination programs and demographic dynamics will affect the epidemiology of varicella and HZ in Germany over the next 50 years. We used a deterministic dynamic compartmental model to assess the impact of different varicella and HZ vaccination strategies on varicella and HZ epidemiology in three demographic scenarios, namely the projected population for Germany, the projected population additionally accounting for increased immigration as observed in 2015/2016, and a stationary population. Projected demographic changes alone result in an increase of annual HZ cases by 18.3% and a decrease of varicella cases by 45.7% between 1990 and 2060. Independently of the demographic scenario, varicella vaccination reduces the cumulative number of varicella cases until 2060 by approximately 70%, but also increases HZ cases by 10%. Unlike the currently licensed live attenuated HZ vaccine, the new subunit vaccine candidate might completely counteract this effect. Relative vaccine effects were consistent across all demographic scenarios. Demographic dynamics will be a major determinant of HZ epidemiology in the next 50 years. While stationary population models are appropriate for assessing vaccination impact, models incorporating realistic population structures allow a direct comparison to surveillance data and can thus provide additional input for immunization decision-making and resource planning.

  20. Demographic Change in the American Geophysical Union's United States Membership, 2006-2014 (United States)

    Rhodes, D. D.


    AGU's demographic characteristics changed during the period 2006-2014 in response to the aging of the Baby Boom generation and an increase in the number of women geoscientists. This analysis deals only with the portion of AGU's membership with mailing addresses within the US, a group that comprised 65% of the worldwide total in 2006 and 61% of the total membership in 2014. Using the US membership data that include both the members' birthdate and gender, a comparison of the population structures in 2006 and 2014 reveals characteristics of the changing US workforce. Since 2006, the percent of the US membership represented by the Baby Boom has decreased 5.2%, from 37.2% to 32.0%. That trend will continue for the next 20 years and the rate will accelerate before slowing again. At the same time the Boomers are decreasing in number, the percentage of the membership represented by the more recent age-cohorts (born 1965-1989) has grown. For example, in 2006, the 1985-1989 cohort was barely represented (0.14%). By February 2014, the cohort had become 8.25% of the U.S. membership. The four cohorts covering birth years 1965 through 1984, each increased slightly in size. In addition, each had a larger number of women, reflecting AGU's increased female membership from 22.5% to 25.3%. The 1985-1989 cohort is somewhat smaller than the previous four cohorts. If the smaller size of this represents a reversal of the growth trend over the last 25 years, the implications for the size of the US workforce are important. Perhaps the most significant change in the demographic structure of AGU's US membership is that the general shape of the age-gender diagram, while still asymmetrical because of the larger number of men, is becoming more straight sided due to the similar size of recent cohorts. This shape is characteristic of stable populations when dealing with self-reproducing groups. The implications for the future of a scientific society are less clear, but the cause reflects a period

  1. Changes in themes over time from medical student journaling. (United States)

    Cayley, William; Schilling, Rae; Suechting, Ralph


    There has been little exploration of journaling in medical student education. To document the themes on which medical students reflect during training. We evaluated journals kept by primary care medical students to identify prominent themes and determine change or constancy in themes over time. We looked at third-year medical students participating in a required primary care clerkship in a university-affiliated, community-based family medicine residency program with a rural catchment area. During 1994-1996 and 2001-2003, students were asked to keep weekly journals reflecting on their thoughts and feelings regarding "topical content, course processes and methods, and personal reflections on becoming a doctor." Faculty evaluated journals to identify change or constancy in themes over time. Prominent themes included gender issues, professional identity emergence, career choice, and rural practice, the experience of learning, the experience of relating to patients, and the nature of medical practice. We found both constancy and change in student journal themes over time. Changes in journal themes appeared to correlate with outside events and educational trends, including increased attention to reflective practice, changing demographics in medicine and the increasing acceptance of female physicians, and personal life events.

  2. The influence of school demographic factors and perceived student discrimination on delinquency trajectory in adolescence. (United States)

    Le, Thao N; Stockdale, Gary


    The purpose of this study was to examine the effects of school demographic factors and youth's perception of discrimination on delinquency in adolescence and into young adulthood for African American, Asian, Hispanic, and white racial/ethnic groups. Using data from the National Longitudinal Study of Adolescent Health (Add Health), models testing the effect of school-related variables on delinquency trajectories were evaluated for the four racial/ethnic groups using Mplus 5.21 statistical software. Results revealed that greater student ethnic diversity and perceived discrimination, but not teacher ethnic diversity, resulted in higher initial delinquency estimates at 13 years of age for all groups. However, except for African Americans, having a greater proportion of female teachers in the school decreased initial delinquency estimates. For African Americans and whites, a larger school size also increased the initial estimates. Additionally, lower social-economic status increased the initial estimates for whites, and being born in the United States increased the initial estimates for Asians and Hispanics. Finally, regardless of the initial delinquency estimate at age 13 and the effect of the school variables, all groups eventually converged to extremely low delinquency in young adulthood, at the age of 21 years. Educators and public policy makers seeking to prevent and reduce delinquency can modify individual risks by modifying characteristics of the school environment. Policies that promote respect for diversity and intolerance toward discrimination, as well as training to help teachers recognize the precursors and signs of aggression and/or violence, may also facilitate a positive school environment, resulting in lower delinquency.

  3. Detecting recent changes in the demographic parameters of drosophilid populations from western and central Africa (United States)

    Bouiges, Axelle; Yassin, Amir; Ikogou, Maya; Lelarge, Clément; Sikoa, Axelle-Rolande; Mona, Stefano; Veuille, Michel


    Previous genetic studies showing evidence of past demographic changes in African drosophilids suggested that these populations had strongly responded to Quaternary climate changes. We surveyed nine species of Zaprionus, a drosophilid genus mostly present in Africa, in forests located between southern Senegal and Gabon. The mitochondrial COI gene showed contrasted levels of sequence variation across species. Populations of the only cosmopolitan species of the genus, Z. indianus, and of its closely related sibling species, Z. africanus, are highly polymorphic and appear to have undergone a continuous population expansion beginning about 130,000 years ago. Five less variable species probably underwent a population expansion beginning only about 20,000-30,000 years ago. One of them, Z. taronus, was significantly structured between forest blocks. The last two species were nearly monomorphic, probably due to infection by Wolbachia. These results are similar to those obtained in three species from the melanogaster subgroup, and may be typical of the responses of African drosophilid populations to glacial cycles.

  4. Intergenerational aspects of government policy under changing demographic and economic conditions. (United States)

    Boskin, M J


    Changing demographic and economic conditions in the US require that attention be given to some of the intergenerational equity features of government policy. In particular, social insurance programs and public debt leave public liabilities to future generations. Taken in the aggregate, the effects of rapidly rising public debt and especially social insurance programs are transferring substantial amounts of resources from younger working generations to the expanding generation of retirees. The most crucial element in evaluating the desirability of intergenerational wealth distribution in the long run is the rate of economic growth. A society's monetary, fiscal, tax, and regulatory policies can be more or less conducive to the generation of capital formation, technical change, and economic growth. Policies that influence growth and interest rates will combine with the national deficit to determine how rapidly the debt grows or shrinks. Present accounting procedures are insufficient to provide quantitative answers to the question of what is the impact of a given program on the age-specific distributions of resources. It is important to reconsider the desirability and efficiency of intergenerational redistributions of wealth in the US. It is likely that current policies are not in line with the principles of efficiency, equity, target effectiveness, and cost effectiveness.

  5. Stability and change in alcohol habits of different socio-demographic subgroups--a cohort study. (United States)

    Sydén, Lovisa; Wennberg, Peter; Forsell, Yvonne; Romelsjö, Anders


    Stability in alcohol habits varies over time and in subgroups, but there are few longitudinal studies assessing stability in alcohol habits by socio-demographic subgroups and potential predictors of stability and change. The aim was to study stability and change in alcohol habits by sex, age, and socio-economic position (SEP). Data derived from two longitudinal population based studies in Sweden; the PART study comprising 19 457 individuals aged 20-64 years in 1998-2000, and the Stockholm Public Health Cohort (SPHC) with 50 067 individuals aged 18-84 years in 2002. Both cohorts were followed-up twice; PART 2000-2003 and 2010, and SPHC 2007 and 2010. Alcohol habits were measured with the Alcohol Use Disorders Identification Test (AUDIT), and with normal weekly alcohol consumption (NWAC). Stability in alcohol habits was measured with intraclass correlation. Odds ratios were estimated in multinomial logistic regression analysis to predict stability in alcohol habits. For the two drinking measures there were no consistent patterns of stability in alcohol habits by sex or educational level. The stability was higher for older age groups and self-employed women. To be a man aged 30-39 at baseline predicted both increase and decrease in alcohol habits. The findings illustrate higher stability in alcohol habits with increasing age and among self-employed women with risky alcohol habits. To be a man and the age 30-39 predicted change in alcohol habits. No conclusive pattern of socio-economic position as predictor of change in alcohol habits was found and other studies of potential predictors seem warranted.

  6. Growth-based Theories for Declining Regions? A Note on Conceptualisations of Demographic Change for Regional Economic Development

    Directory of Open Access Journals (Sweden)

    Anke Matuschewski


    Full Text Available This article aims to critically assess the economic growth paradigm, which typically underlies most approaches to regional policymaking for demographic change. While population losses, ageing and outmigration – i.e. phenomena that are addressed as demographic change – have become a matter of urgency for many European regions, most regional economic development theories remain silent about the population decline affecting the economic growth and development prospects of regions. Consequently, regional policies usually rely on the concept of economic growth, yet neglect the complexity and importance of demographic change and how it relates to the economic sphere. Due to this lack in nuance, we argue that regional policymaking fails to design adequate policy support for regions facing persistent demographic change and economic stagnation or decline as a result. Based on these observations, the paper examines a selection of regional economic development theories in search for alternative concepts of growth and development in the context of demographic change. To this aim, globalisation peripheries are introduced as a fruitful conceptual point of reference and, in combination with endogenous regional development theories, discussed as an alternative approach for regional policymaking.

  7. Changes in the Demographic Characteristics of the American Geophysical Union Membership, 2006-2010 (United States)

    Rhodes, D. D.


    Significant change occurred in the demographic properties of the American Geophysical Union membership during the period April 2006- January 2010. During this period AGU membership decreased from 48,332 to 38,847, a drop of 19.6%. Most of the change appears to have been driven by the aging membership of the Union, especially in the United States, and the effects of the global economic crisis on employment in all sectors of economy. Of the 38,847 members in January 2010, data on the birth year and gender were available for 33,610 members including 21,567 who reside in the United States. These data were compared to a similar data set captured in April 2006. The following observations are based on this subset of the total AGU membership for who country of residence and both age and gender are known. The number of AGU members residing in the United States decreased by 18.6% during the study period. As should be expected, the changes were not spread evenly between the genders or across birth-year cohorts. Membership among males decreased by 19%, while there were 17% fewer female members. The female cohorts that experienced the greatest losses were those including women from 30-40 years old (born 1970-1979). These data appear to echo multiple studies that show women leaving the sciences for gender-specific reasons. For the purposes of this analysis, the birth-year cohorts are divided into three groups. Members born prior to 1945 compose the oldest cohort. The Baby-Boom generation includes members born between 1945 and 1964. The youngest group includes members born from 1965 onward. Because of the very small number of women in the oldest group (only 4.7%) most of the change occurred among males. The total membership loss from this group was 1,140 members, 23% of the total. The largest change occurred among Baby Boomers. The group decreased by 2,760 members, accounting for 56% of the total decline in membership among US residents. Males accounted for most of the change (2

  8. Demographics and complaints of university students who sought help at a campus mental health service between 1987 and 2004. (United States)

    Oliveira, Maria Lilian Coelho de; Dantas, Clarissa de Rosalmeida; Azevedo, Renata Cruz Soares de; Banzato, Cláudio Eduardo Muller


    Client characterization is an important step in evaluating the services offered by campus counseling and mental health centers and in their further planning and development. The objectives here were to describe reported complaints and demographics among students who sought counseling/mental healthcare at a Brazilian campus mental health service over a 17-year period and to compare these characteristics with those of the general university student body. Retrospective study at the Psychological and Psychiatric Service for Students (SAPPE), Universidade Estadual de Campinas (Unicamp). The participants were all of the 2,194 students who sought counseling/mental health care at SAPPE from 1987 to 2004. Information was obtained from clients clinical charts. Unicamps database was consulted for general information on its students. The findings indicated overrepresentation, among the clients, of undergraduates, female students, students from Brazilian states other than São Paulo, students living in the campus residence hall and those whose main source of income was a scholarship grant. We also found overrepresentation of Humanities and Arts students among the clients. The most frequently reported complaints were difficulties in interpersonal relationships, family conflicts and poor academic performance. Course level (undergraduate or postgraduate), study field, living in a university residential facility and reliance on a scholarship grant were found to influence the behavior of seeking mental health counseling among Brazilian university students in this study. Course level was found to influence the pattern of complaints reported at first contact with the mental health service.

    Full Text Available This paper considers whether the US Appalachian Regional Commission (ARC Asset-Based Development Initiative (ABDI reconciles economic development objectives in communities experiencing demographic change. Through a case study approach utilizing key informant interviews in Southwest Virginia communities and a review of ARC-funded projects, the authors consider two main questions. Did community leadership change or adapt to the program? Were new projects demonstrably different in objectives, content, or outcomes than past projects? Economic and demographic similarities between Alpine and Appalachian communities, particularly in the role of in-migrants, suggest that this study’s findings will be relevant for other mountain regions and could contribute to a conversation among international scholars of mountain development.Cet article cherche à déterminer si l’initiative de développement basé sur les ressources (ABDI, Asset-Based Development Initiative de la Commission régionale des Appalaches (ARC, Appalachian Regional Commission aux États-Unis réconcilie les objectifs de développement économique dans les communautés qui présentent un changement démographique. À travers des études de cas reposant sur des entretiens informatifs clés menés dans les communautés de la Virginie Occidentale et un examen de projets financés par l’ARC, les auteurs tentent de répondre à deux questions fondamentales : « Le leadership communautaire a-t-il évolué et s’est-il adapté au programme ? » et « Les nouveaux projets différaient-ils clairement, en termes d’objectifs, de contenu ou de résultats, des projets antérieurs ? ». Les similitudes économiques et démographiques entre les communautés alpines et appalachiennes, notamment en ce qui concerne le rôle des immigrants, suggèrent que les conclusions de cette étude seront pertinentes pour d’autres régions de montagnes et pourraient contribuer à un débat entre sp

  10. Demographic and Lifestyle Characteristics, but Not Apolipoprotein E Genotype, Are Associated with Intelligence among Young Chinese College Students.

    Directory of Open Access Journals (Sweden)

    Xiao-Fen Chen

    Full Text Available Intelligence is an important human feature that strongly affects many life outcomes, including health, life-span, income, educational and occupational attainments. People at all ages differ in their intelligence but the origins of these differences are much debated. A variety of environmental and genetic factors have been reported to be associated with individual intelligence, yet their nature and contribution to intelligence differences have been controversial.To investigate the contribution of apolipoprotein E (APOE genotype, which is associated with the risk for Alzheimer's disease, as well as demographic and lifestyle characteristics, to the variation in intelligence.A total of 607 Chinese college students aged 18 to 25 years old were included in this prospective observational study. The Chinese revision of Wechsler Adult Intelligence Scale (the fourth edition, short version was used to determine the intelligence level of participants. Demographic and lifestyle characteristics data were obtained from self-administered questionnaires.No significant association was found between APOE polymorphic alleles and different intelligence quotient (IQ measures. Interestingly, a portion of demographic and lifestyle characteristics, including age, smoking and sleep quality were significantly associated with different IQ measures.Our findings indicate that demographic features and lifestyle characteristics, but not APOE genotype, are associated with intelligence measures among young Chinese college students. Thus, although APOE ε4 allele is a strong genetic risk factor for Alzheimer's disease, it does not seem to impact intelligence at young ages.

  11. Predicting bicycle helmet stage-of-change among middle school, high school, and college cyclists from demographic, cognitive, and motivational variables. (United States)

    Weiss, Jeffrey; Okun, Morris; Quay, Nancy


    To apply Prochaska's Transtheoretical model of behavior change to bicycle helmet use among middle school, high school, and college students. A battery of questionnaires was administered to cyclists in the seventh and ninth grades and to college students in Phoenix, Arizona (N=797). The battery included: (1) a question to determine respondent's stage of behavior change in Prochaska's Transtheoretical model; (2) items assessing the perceived pros and cons of helmet use; (3) a bicycle safety knowledge test; and (4) demographic information. Forty-three percent of the students were in "Precontemplation," 17% were in either "Contemplation" or "Preparation," 16% were in either "Action" or "Maintenance," and 24% were in the "Relapse" stage of change. Grade, Sex, Knowledge, Pros, and Cons, and the Grade by sex and the Grade by knowledge interactions were significant predictors of helmet use stages. Compared with students in Precontemplation, students in the Contemplation stage were disproportionately younger and had higher Pro scores, lower Con scores, and more knowledge (except in the ninth grade). The Transtheoretical model of behavior change is a viable theoretical framework for designing interventions aimed at increasing bicycle helmet use in children and adolescents.

    Abstract Introduction. Behavioral factors of health are an important area of empirical cognition from the perspective of long-term individual as well as social investment in health. Aim. The assessment of health behaviors and their differentiation due to selected socio-demographic and environmental-cultural characteristics in a group of young adults. Materials and methods. Cross-sectional studies in the group of students of the city of Lublin were performed using the Health Behavior Inventory (HBI by Z. Juczyński. The study also included the survey questions in the field of socio-demographic and cultural- environmental indicators. Results. The analysis concerned data on 1,593 randomly selected people (63.53% women, 36.47% men, aged 20-35 years (x = 22.16, SD =2.81. In the group, at 45.07% of students, the rate of intensity of health behaviors according to HBI was low, at 39.60% - was the average, and in only 11.30% -it was high. Conclusions. In the group, low rates of health behaviors intensity predominated. Among women, the students of medical university, non-smokers and those characterized by regular physical activity a higher level of health behaviors was shown.   Key words: behavioral factors, socio-demographic indicators, health status, young adults.

  14. Changing maternity leave policy: short-term effects on fertility rates and demographic variables in Germany. (United States)

    Thyrian, Jochen René; Fendrich, Konstanze; Lange, Anja; Haas, Johannes-Peter; Zygmunt, Marek; Hoffmann, Wolfgang


    Changes in reproductive behaviour and decreasing fertility rates have recently led to policy actions that attempt to counteract these developments. Evidence on the efficacy of such policy interventions, however, is limited. The present analysis examines fertility rates and demographic variables of a population in Germany in response to new maternity leave regulations, which were introduced in January 2007. As part of a population-based survey of neonates in Pomerania (SNiP), all births in the study region from the period 23 months prior to January 1st, 2007 until 23 months afterwards were examined. Crude Birth Rates (CBR) per month, General Fertility Rates (GFR) per month, parity and sociodemographic variables were compared using bivariate techniques. Logistic regression analysis was performed. No statistically significant difference in the CBR or GFR after Jan. 1st, 2007 was found. There were statistically significant differences in other demographic variables, however. The proportion of mothers who (a) were employed full-time before pregnancy; (b) came from a higher socioeconomic status; and (c) had higher income levels all increased after January 1st, 2007. The magnitude of these effects was higher in multigravid women. Forward stepwise logistic regression found an odds ratio of 1.79 for women with a family income of more than 3000 euro to give birth after the new law was introduced. This is the first analysis of population-based data that examines fertility rates and sociodemographic variables in response to new legal regulations. No short-term effects on birth rates were detected, but there was a differential effect on the subgroup of multigravidae. The focus of this policy was to provide financial support, which is certainly important, but the complexity of having a child suggests that attitudinal and motivational aspects also need to be taken into account. Furthermore, these analyses were only able to evaluate the short-term consequences of the policy

  15. Hidden Losses: How Demographics Can Encourage Incorrect Assumptions about ESL High School Students' Success (United States)

    Data from ESL students' records in Vancouver are examined in the light of the BC Ministry of Education's claim that ESL high school students are more successful than students whose first language is English. We argue that the academic achievement of well-to-do students whose parents are skilled workers or entrepreneurs may mask the completion…

  16. Comparative description of migrant farmworkers versus other students attending South Texas schools: demographic, academic, and health characteristics. (United States)

    Cooper, Sharon P; Weller, Nancy F; Fox, Erin E; Cooper, Sara R; Shipp, Eva M


    Little is known about academic performance, health, and social functioning of youth from migrant farmworker families. This study was designed to compare demographic, academic, health, and social data between migrant and nonmigrant youth residing in South Texas. Anonymous cross-sectional survey data were collected from 6954 middle and 3565 high school students. About 5% of South Texas middle and high school students reported belonging to a migrant family. Compared with nonmigrant students, migrant youth were more likely to miss and arrive late to school, sleep in class, and study fewer hours weekly. Migrant students reported fewer hours of nightly sleep, fewer hours spent with their friends, and more minor illnesses than nonmigrant youth. These results demonstrate the need for interventions specifically targeted to this vulnerable adolescent population.

  18. Socio-demographic impacts on lane-changing response time and distance in work zone with Drivers' Smart Advisory System

    Directory of Open Access Journals (Sweden)

    Qing Li


    Full Text Available Lane-changing behavior is an important component of traffic simulation. A lane-changing action is normally confined to a decision-making process of the task, and the action itself is sometimes assumed as an instantaneous event. Besides, the lane-changing behavior is based mostly on observable positions and speeds of other vehicles, rather than on vehicles' intentions. In practice, changing one lane requires about 5–6 s to complete. Existing lane-changing models do not comprehensively consider drivers' response to work zone lane-changing signs (or other related messages, if any. Furthermore, drivers' socio-demographics are normally not taken into account. With regard to this, fuzzy logic-based lane-changing models that consider drivers' socio-demographics were developed to improve the realism of lane-changing maneuvers in work zones. Drivers' Smart Advisory System (DSAS messages were provided as one of the scenarios. Drivers' responses, including reactions to work zone signs and DSAS messages, and actions to change lane, were investigated. Drivers' socio-demographic factors were primary independent variables, while Lane-Changing Response Time (LCRT and Distance (LCRD were defined as output variables. The model validation process yielded acceptable error ranges. To illustrate how these models can be used in traffic simulation, the LCRT and LCRD in work zones were estimated for five geo-locations with different socio-demographic specifications. Results show that the DSAS is able to instruct all drivers to prepare and change lanes earlier, thereby shortening the duration of changing lanes. Educational background and age are essential variables, whereas the impacts of gender on the output variables are indistinctive.

  19. Climate Change Awareness among the High School Students: Case Study from a Climate Vulnerable Country

    Directory of Open Access Journals (Sweden)

    S.M.A. Rahman


    Full Text Available Bangladesh is one the worst sufferers of climate change. Climate change awareness creation is pivotal to adaptation and mitigation strategies. Effective dissemination of knowledge among the citizens during high school years is crucial to that end. In Bangladesh, secondary school students follow common curricula which include entries on climate change. This paper investigates the role of the diverse demographic profiles and inherent scholastic background of students on their informedness. The research is based on responses from secondary schools students in Chittagong, Bangladesh. Based on their understanding of climate change, we have constructed the Climate Awareness Index (CAI. Then the relative roles of demographic determinants of the awareness have been compared using the CAI. The quality of schools, and grade, major and merit position of students have affected the CAI values. Besides, the study concluded that the religion, gender, parental education, occupation and income, etc. could affect students’ climate change informedness in Bangladesh.

  1. Holocene Demographic Changes and the Emergence of Complex Societies in Prehistoric Australia.

    Directory of Open Access Journals (Sweden)

    Alan N Williams

    Full Text Available A continental-scale model of Holocene Australian hunter-gatherer demography and mobility is generated using radiocarbon data and geospatial techniques. Results show a delayed expansion and settlement of much of Australia following the termination of the late Pleistocene until after 9,000 years ago (or 9ka. The onset of the Holocene climatic optimum (9-6ka coincides with rapid expansion, growth and establishment of regional populations across ~75% of Australia, including much of the arid zone. This diffusion from isolated Pleistocene refugia provides a mechanism for the synchronous spread of pan-continental archaeological and linguistic attributes at this time (e.g. Pama-Nyungan language, Panaramitee art style, backed artefacts. We argue longer patch residence times were possible at the end of the optimum, resulting in a shift to more sedentary lifestyles and establishment of low-level food production in some parts of the continent. The onset of El Niño - Southern Oscillation (ENSO; 4.5-2ka restricted low-level food production, and resulted in population fragmentation, abandonment of marginal areas, and reduction in ranging territory of ~26%. Importantly, climate amelioration brought about by more pervasive La Niña conditions (post-2ka, resulted in an intensification of the mobility strategies and technological innovations that were developed in the early- to mid-Holocene. These changes resulted in population expansion and utilization of the entire continent. We propose that it was under these demographically packed conditions that the complex social and religious societies observed at colonial contact were formed.

  4. Cross-cultural and socio-demographic correlates of homophobic attitude among university students in three European countries. (United States)

    Ciocca, G; Niolu, C; Déttore, D; Antonelli, P; Conte, S; Tuziak, B; Limoncin, E; Mollaioli, D; Carosa, E; Gravina, G L; Di Sante, S; Di Lorenzo, G; Fisher, A D; Maggi, M; Lenzi, A; Siracusano, A; Jannini, E A


    The aim of this study was to investigate homophobic attitudes in three European countries: Italy, Albania, and Ukraine. One thousand and forty-eight students were recruited in Italian (n = 766), Albanian (n = 180), and Ukrainian (n = 102) university centers. A socio-demographic questionnaire and Homophobia Scale (HS) were administered by our staff. Cross-cultural and significant differences among Italian, Albanian, and Ukrainian students were found on the Homophobia Scale (HS; Italy: mean = 22.26 ± 16.73; Albania: mean = 38.15 ± 17.28; Ukraine: mean = 59.18 ± 16.23). The analysis of socio-demographic characteristics revealed that the male gender emerged as main predictor of homophobic attitude in all the three countries, although also a conservative political orientation and the religious belief predict higher homophobia levels in Italy and Albania, particularly. This study revealed that in these European countries assessed, attitudes toward homosexuality are different. Ukrainians display higher levels of homophobia than Albanians and Italians, confirming the central role of cultural differences in homophobic attitudes. Nevertheless, some socio-demographic aspects such as identification as male have a similar influence on homophobic attitudes in all assessed populations.

  8. Increasing weather-related impacts on European population under climate and demographic change (United States)

    Forzieri, Giovanni; Cescatti, Alessandro; Batista e Silva, Filipe; Kovats, Sari R.; Feyen, Luc


    Over the last three decades the overwhelming majority of disasters have been caused by weather-related events. The observed rise in weather-related disaster losses has been largely attributed to increased exposure and to a lesser degree to global warming. Recent studies suggest an intensification in the climatology of multiple weather extremes in Europe over the coming decades in view of climate change, while urbanization continues. In view of these pressures, understanding and quantifying the potential impacts of extreme weather events on future societies is imperative in order to identify where and to what extent their livelihoods will be at risk in the future, and develop timely and effective adaptation and disaster risk reduction strategies. Here we show a comprehensive assessment of single- and multi-hazard impacts on the European population until the year 2100. For this purpose, we developed a novel methodology that quantifies the human impacts as a multiplicative function of hazard, exposure and population vulnerability. We focus on seven of the most impacting weather-related hazards - including heat and cold waves, wildfires, droughts, river and coastal floods and windstorms - and evaluated their spatial and temporal variations in intensity and frequency under a business-as-usual climate scenario. Long-term demographic dynamics were modelled to assess exposure developments under a corresponding middle-of-the-road scenario. Vulnerability of humans to weather extremes was appraised based on more than 2300 records of weather-related disasters. The integration of these elements provides a range of plausible estimates of extreme weather-related risks for future European generations. Expected impacts on population are quantified in terms of fatalities and number of people exposed. We find a staggering rise in fatalities from extreme weather events, with the projected death toll by the end of the century amounting to more than 50 times the present number of people

    Maria Lilian Coelho de Oliveira

    Full Text Available CONTEXT AND OBJECTIVE: Client characterization is an important step in evaluating the services offered by campus counseling and mental health centers and in their further planning and development. The objectives here were to describe reported complaints and demographics among students who sought counseling/mental healthcare at a Brazilian campus mental health service over a 17-year period and to compare these characteristics with those of the general university student body. DESIGN AND SETTING: Retrospective study at the Psychological and Psychiatric Service for Students (SAPPE, Universidade Estadual de Campinas (Unicamp. METHODS: The participants were all of the 2,194 students who sought counseling/mental health care at SAPPE from 1987 to 2004. Information was obtained from clients’ clinical charts. Unicamp’s database was consulted for general information on its students. RESULTS: The findings indicated overrepresentation, among the clients, of undergraduates, female students, students from Brazilian states other than São Paulo, students living in the campus residence hall and those whose main source of income was a scholarship grant. We also found overrepresentation of Humanities and Arts students among the clients. The most frequently reported complaints were difficulties in interpersonal relationships, family conflicts and poor academic performance. CONCLUSION: Course level (undergraduate or postgraduate, study field, living in a university residential facility and reliance on a scholarship grant were found to influence the behavior of seeking mental health counseling among Brazilian university students in this study. Course level was found to influence the pattern of complaints reported at first contact with the mental health service.

  10. Incorporating Student Activities into Climate Change Education (United States)

    Steele, H.; Kelly, K.; Klein, D.; Cadavid, A. C.


    Under a NASA grant, Mathematical and Geospatial Pathways to Climate Change Education, students at California State University, Northridge integrated Geographic Information Systems (GIS), remote sensing, satellite data technologies, and climate modelling into the study of global climate change under a Pathway for studying the Mathematics of Climate Change (PMCC). The PMCC, which is an interdisciplinary option within the BS in Applied Mathematical Sciences, consists of courses offered by the departments of Mathematics, Physics, and Geography and is designed to prepare students for careers and Ph.D. programs in technical fields relevant to global climate change. Under this option students are exposed to the science, mathematics, and applications of climate change science through a variety of methods including hands-on experience with computer modeling and image processing software. In the Geography component of the program, ESRI's ArcGIS and ERDAS Imagine mapping, spatial analysis and image processing software were used to explore NASA satellite data to examine the earth's atmosphere, hydrosphere and biosphere in areas that are affected by climate change or affect climate. These technology tools were incorporated into climate change and remote sensing courses to enhance students' knowledge and understanding of climate change through hands-on application of image processing techniques to NASA data. Several sets of exercises were developed with specific learning objectives in mind. These were (1) to increase student understanding of climate change and climate change processes; (2) to develop student skills in understanding, downloading and processing satellite data; (3) to teach remote sensing technology and GIS through applications to climate change; (4) to expose students to climate data and methods they can apply to solve real world problems and incorporate in future research projects. In the Math and Physics components of the course, students learned about

    delineation of boundaries of federal electoral districts. As argued in this paper,the traditional understandings and agreements that have shaped decisions relating to electoral districts are increasingly at odds with Canada’s emerging demographic realities. In a nation that is highly reliant on immigration in maintaining its population, the current representational order arguably penalizes regions of the country which are growing most rapidly, and in particular, where new immigrants are most likely to locate. The current paper also considers possible reforms in the manner in which electoral districts are drawn, which at a minimum could involve the use of more up to date and accurate demographic data.

  12. Spatial Pattern and Scale Influence Invader Demographic Response to Simulated Precipitation Change in an Annual Grassland Community.

    Directory of Open Access Journals (Sweden)

    Meghan J Skaer Thomason

    Full Text Available It is important to predict which invasive species will benefit from future changes in climate, and thereby identify those invaders that need particular attention and prioritization of management efforts. Because establishment, persistence, and spread determine invasion success, this prediction requires detailed demographic information. Explicit study of the impact of pattern on demographic response is particularly important for species that are naturally patchy, such as the invasive grass, Aegilops triuncialis. In the northern California Coast Range, where climate change may increase or decrease mean annual rainfall, we conducted a field experiment to understand the interaction of climate change and local-scale patterning on the demography of A. triuncialis. We manipulated precipitation (reduced, ambient, or augmented, seed density, and seeding pattern. Demographic and environmental data were collected for three years following initial seeding. Pattern and scale figure prominently in the demographic response of A. triuncialis to precipitation manipulation. Pattern interacts with precipitation and seeding density in its influence on per-plant seed output. Although per-plot seed production was highest when seeds were not aggregated, per-plant seed output was higher in aggregated patches. Results suggest aggregation of invasive A. triuncialis reduces the detrimental impact of interspecific competition in its invaded community, and that interspecific competition per se has a stronger impact than intraspecific competition.

  14. Students as Prosocial Bystanders to Sexual Assault: Demographic Correlates of Intervention Norms, Intentions, and Missed Opportunities. (United States)

    Hoxmeier, Jill C; Acock, Alan C; Flay, Brian R


    Sexual assault is a major public health issue. Bystander engagement programs are becoming widely used to combat sexual assault on college campuses. The purpose of this study was to examine students' intervention norms, intentions, opportunities, and behaviors as bystanders to sexual assault. Undergraduate students ( N = 779) completed the Sexual Assault Bystander Behavior Questionnaire in the fall of 2014. The t tests revealed differences in students' intervention norms, intentions, opportunities, and missed opportunities based on sex, race/ethnicity, athletic participation, and fraternity/sorority membership. The findings support the use of additional measures to assess bystander behavior and to identify student subpopulations that may benefit from programs aimed at increasing prosocial intervention.

  15. Adult anthropometric measures and socio-demographic factors influencing age at menarche of university students in malaysia. (United States)

    Hossain, Md Golam; Wee, Ai-Sze; Ashaie, Maeirah; Kamarul, T


    Early onset of menarche has been shown to be associated with breast cancer and ischaemic heart disease. Studies on age at menarche of the Malaysian population are poorly documented. This study aimed to determine the influence of anthropometric and socio-demographic factors on the age at menarche of university students in Malaysia. Data were obtained in 2010-11 from 961 students between the ages of 18 and 25 years from the University of Malaya using stratified sampling, and multiple regression analysis was applied. Sixty-three per cent of students reached menarche at the age of 12 or 13 years, with the mean and median of age at menarche being 12.45 ± 1.17 and 12.01 years, respectively. Menarcheal age was positively associated with height (pObese and overweight students reached menarche earlier than students who were underweight or of normal weight (p<0.01). The variations in age at menarche among the Malaysian ethnic groups were statistically insignificant. The results suggest that heavier and first-born students from small families are more likely to attain menarche earlier than their counterparts.

  16. College Students' Health Information Activities on Facebook: Investigating the Impacts of Health Topic Sensitivity, Information Sources, and Demographics. (United States)

    Syn, Sue Yeon; Kim, Sung Un


    College students tend to lack access to health information. Because social networking sites (SNSs) are popularly adopted by college students, SNSs are considered to be good media channels for college students to obtain health-related information. This study examines the factors that influence college students' health information-seeking and -sharing activities on Facebook. An online survey was distributed to college students between the ages of 18 and 29 to determine intentions pertaining to health information activities according to the factors identified for the study. The factors included both contextual factors (such as health topic sensitivity and health information sources) as well as user factors (such as demographics). Our findings showed that college students are willing to read and post health-related information on Facebook when the health topic is not sensitive. In addition, there are clear differences in preferences between professional sources and personal sources as health information sources. It was found that most user factors, except gender, have no influence on health information activities. The impacts of SNS contexts, awareness of information sources, types of interlocutors, and privacy concerns are further discussed.

  17. Socio-demographic characteristics associated with cigarettes smoking, drug abuse and alcohol drinking among male medical university students in Iran. (United States)

    Jalilian, Farzad; Karami Matin, Behzad; Ahmadpanah, Mohammad; Ataee, Mari; Ahmadi Jouybari, Touraj; Eslami, Ahmad Ali; Mirzaei Alavijeh, Mehdi


    Substance abuse is one of the most complicated social problems. Understanding socio-demographic characteristics of those who abuse substances could help deal with this problem more efficiently. The main objective of this study was to determine socio-demographic characteristics associated with alcohol drinking, cigarettes smoking and drug abuse among a sample of male medical university students in Iran. This cross-sectional study was conducted in 2014 among 425 male medical college students randomly selected with the proportional to size among different faculties in Isfahan and Kermanshah medical universities in Iran. A self-report written questionnaire was applied to collect data. Data were analyzed by the SPSS-20. Mean age of the respondents was 19.9 yr (ranging from 18 to 22 yr). About 19.4%, 3.9%, and 10.1% of the respondents had history of cigarette smoking, drug use, and alcohol drinking during the past three months, respectively. Logistic regression showed that mother's educational level, living place, economic status, and parents' divorce were the most influential predictive factors on substance abuse. Considering the high prevalence of substance abuse (especially smoking and alcohol drinking), it seems essential to design educational interventions to prevent substance abuse, paying attention to predictive factors mentioned above, among college students.

  18. Impact of Quaternary climatic changes and interspecific competition on the demographic history of a highly mobile generalist carnivore, the coyote. (United States)

    Koblmüller, Stephan; Wayne, Robert K; Leonard, Jennifer A


    Recurrent cycles of climatic change during the Quaternary period have dramatically affected the population genetic structure of many species. We reconstruct the recent demographic history of the coyote (Canis latrans) through the use of Bayesian techniques to examine the effects of Late Quaternary climatic perturbations on the genetic structure of a highly mobile generalist species. Our analysis reveals a lack of phylogeographic structure throughout the range but past population size changes correlated with climatic changes. We conclude that even generalist carnivorous species are very susceptible to environmental changes associated with climatic perturbations. This effect may be enhanced in coyotes by interspecific competition with larger carnivores.

    Maria Ramona S. Braza


    Full Text Available This study determined the career choice of the high school students of the different private institutions in San Jose, Batangas as a basis for developing a career program guide to help the students in choosing their career.The descriptive method was used the study with the questionnaire and standardized test as the main data gathering instruments. Parents, students and teachers served as respondents of the study. The study revealed that most preferred career of the respondents is the academic track particularly the Science Technology Engineering and Mathematics (STEM strand. The proposed program guide formulated focused on how to help the students decide on their future career. When properly given, it will benefit the students. The researchers recommended that the proposed career program guide that has been formulated may be shown to school heads for their suggestions; the students should be provided with effective orientation on what career is really all about. This could be done by the school guidance counselor or by the teachers and parents as well and there must be a close–up tie among the guidance personnel, teachers, students, and parents to promote a better understanding of the factors which influence the career choice of the students.

  8. Improving Demographic Components of Integrated Assessment Models: The Effect of Changes in Population Composition by Household Characteristics

    Energy Technology Data Exchange (ETDEWEB)

    Brian C. O' Neill


    This report describes results of the research project on "Improving Demographic Components of Integrated Assessment Models: The Effect of Changes in Population Composition by Household Characteristics". The overall objective of this project was to improve projections of energy demand and associated greenhouse gas emissions by taking into account demographic factors currently not incorporated in Integrated Assessment Models (IAMs) of global climate change. We proposed to examine the potential magnitude of effects on energy demand of changes in the composition of populations by household characteristics for three countries: the U.S., China, and Indonesia. For each country, we planned to analyze household energy use survey data to estimate relationships between household characteristics and energy use; develop a new set of detailed household projections for each country; and combine these analyses to produce new projections of energy demand illustrating the potential importance of consideration of households.

  10. Demographic and behavioural correlates of six sexting behaviours among Australian secondary school students. (United States)

    Patrick, Kent; Heywood, Wendy; Pitts, Marian K; Mitchell, Anne


    Background There has been increasing attention on assessing rates of sexting in adolescents and of the potential negative effects of the behaviour. Our aim was to assess rates and correlates of sexting in Australian students in years10, 11 and 12. The current study was part of The Fifth National Survey of Australian Secondary Students and Sexual Health and reports on responses of 2114 students (811 male, 1303 female). Sexting was assessed using six items: sending a sexually explicit written text message; receiving a sexually explicit text message; sending a sexually explicit nude or nearly nude photo or video of themselves; sending a sexually explicit nude or nearly nude photo or video of someone else; receiving a sexually explicit nude or nearly nude photo or video of someone else; and using a social media site for sexual reasons. Approximately half of the students had received (54%, 1139/2097) or sent (43%, 904/2107) a sexually explicit written text message. Sexually explicit images had been received by 42% (880/2098) of students, one in four students had sent a sexually explicit image of themselves (26%, 545/2102) and one in 10 had sent a sexually explicit image of someone else (9%, 180/2095). Finally, 22% (454/2103) of students had used social media for sexual reasons. Sexting was associated with several correlates. Sexting was relatively common in this sample of year 10, 11 and 12 Australian students, particularly among older students, those who are sexually active, and those who use recreational substances.

  11. Feeling threatened about the future: Whites' emotional reactions to anticipated ethnic demographic changes. (United States)

    Outten, H Robert; Schmitt, Michael T; Miller, Daniel A; Garcia, Amber L


    In many Western countries, the proportion of the population that is White will drop below 50% within the next century. Two experiments examined how anticipation of these future ethnic demographics affects current intergroup processes. In Study 1, White Americans who viewed actual demographic projections for a time when Whites are no longer a numerical majority felt more angry toward and fearful of ethnic minorities than Whites who did not view future projections. Whites who viewed the future projections also felt more sympathy for their ingroup than Whites in the control condition. In Study 2, the authors replicated the effects for intergroup emotions with a sample of White Canadians. White Canadians who thought about a future in which Whites were a numerical minority appraised the ingroup as more threatened, which mediated the effect of condition on intergroup emotions. The authors discuss the implications of these findings for race relations in increasingly diverse societies.

  12. The demographic changes of the last quarter of century in Romania

    Directory of Open Access Journals (Sweden)

    Adriana Veronica LITRA


    Full Text Available The year 1990 has delimited two different demographic periods in Romania: the first, defined as Stage 2 in the Demographic Transition Model (as in Population Education, USA, characterized by low mortality rates due to advances in medical, and high birth rates, resulting rapid population growth; after 1990, Romania moved to Stage 5, having a negative growth rate due to less births than deaths, and a negative net migration rate. Romania is experiencing a falling population with birth rates at 8.3 births per 1,000 persons and death rates at 11.4 per 1,000 persons in 2014. The total fertility rate fell significantly below the replacement level of generations (1.4 live births per woman in 2014, reversing the proportion of elderly in detriment of the youth.

  14. Which came first, people or pollution? Assessing the disparate siting and post-siting demographic change hypotheses of environmental injustice

    International Nuclear Information System (INIS)

    Mohai, Paul; Saha, Robin


    Although a large body of quantitative environmental justice research exists, only a handful of studies have examined the processes by which racial and socioeconomic disparities in the location of polluting industrial facilities can occur. These studies have had mixed results, we contend, principally because of methodological differences, that is, the use of the unit-hazard coincidence method as compared to distance-based methods. This study is the first national-level environmental justice study to conduct longitudinal analyses using distance-based methods. Our purposes are to: (1) determine whether disparate siting, post-siting demographic change, or a combination of the two created present-day disparities; (2) test related explanations; and (3) determine whether the application of distance-based methods helps resolve the inconsistent findings of previous research. We used a national database of commercial hazardous waste facilities sited from 1966 to 1995 and examined the demographic composition of host neighborhoods around the time of siting and demographic changes that occurred after siting. We found strong evidence of disparate siting for facilities sited in all time periods. Although we found some evidence of post-siting demographic changes, they were mostly a continuation of changes that occurred in the decade or two prior to siting, suggesting that neighborhood transition serves to attract noxious facilities rather than the facilities themselves attracting people of color and low income populations. Our findings help resolve inconsistencies among the longitudinal studies and builds on the evidence from other subnational studies that used distance-based methods. We conclude that racial discrimination and sociopolitical explanations (i.e., the proposition that siting decisions follow the ‘path of least resistance’) best explain present-day inequities.

  16. Demographics of undergraduates studying games in the United States: a comparison of computer science students and the general population (United States)

    McGill, Monica M.; Settle, Amber; Decker, Adrienne


    Our study gathered data to serve as a benchmark of demographics of undergraduate students in game degree programs. Due to the high number of programs that are cross-disciplinary with computer science programs or that are housed in computer science departments, the data is presented in comparison to data from computing students (where available) and the US population. Participants included students studying games at four nationally recognized postsecondary institutions. The results of the study indicate that there is no significant difference between the ratio of men to women studying in computing programs or in game degree programs, with women being severely underrepresented in both. Women, blacks, Hispanics/Latinos, and heterosexuals are underrepresented compared to the US population. Those with moderate and conservative political views and with religious affiliations are underrepresented in the game student population. Participants agree that workforce diversity is important and that their programs are adequately diverse, but only one-half of the participants indicated that diversity has been discussed in any of their courses.

  17. The relationships of coping, negative thinking, life satisfaction, social support, and selected demographics with anxiety of young adult college students. (United States)

    Mahmoud, Jihan S R; Staten, Ruth Topsy; Lennie, Terry A; Hall, Lynne A


    Understanding young adults' anxiety requires applying a multidimensional approach to assess the psychosocial, behavioral, and cognitive aspects of this phenomenon. A hypothesized model of the relationships among coping style, thinking style, life satisfaction, social support, and selected demographics and anxiety among college students was tested using path analysis. A total of 257 undergraduate students aged 18-24 years completed an online survey. The independent variables were measured using the Multidimensional Scale of Perceived Social Support, the Brief Students' Multidimensional Life Satisfaction Scale, the Brief COPE Inventory, the Positive Automatic Thoughts Questionnaire, and the Cognition Checklist-Anxiety. The outcome, anxiety, was measured using the Anxiety subscale of the 21-item Depression Anxiety and Stress Scale. Only negative thinking and maladaptive coping had a direct relationship with anxiety. Negative thinking was the strongest predictor of both maladaptive coping and anxiety. These findings suggest that helping undergraduates manage their anxiety by reducing their negative thinking is critical. Designing and testing interventions to decrease negative thinking in college students is recommended for future research. © 2015 Wiley Periodicals, Inc.

  19. On the contribution of demographic change to aggregate poverty measures for the developing world


    Ravallion, Martin


    Recent literature and new data help determine plausible bounds to some key demographic differences between the poor and non-poor in the developing world. The author estimates that selective mortality-whereby poorer people tend to have higher death rates-accounts for 10-30 percent of the developing world's trend rate of "$1 a day" poverty reduction in the 1990s. However, in a neighborhood of plausible estimates, differential fertility-whereby poorer people tend also to have higher birth rates-...

  4. Estimating synchronous demographic changes across populations using hABC and its application for a herpetological community from northeastern Brazil. (United States)

    Gehara, Marcelo; Garda, Adrian A; Werneck, Fernanda P; Oliveira, Eliana F; da Fonseca, Emanuel M; Camurugi, Felipe; Magalhães, Felipe de M; Lanna, Flávia M; Sites, Jack W; Marques, Ricardo; Silveira-Filho, Ricardo; São Pedro, Vinícius A; Colli, Guarino R; Costa, Gabriel C; Burbrink, Frank T


    Many studies propose that Quaternary climatic cycles contracted and/or expanded the ranges of species and biomes. Strong expansion-contraction dynamics of biomes presume concerted demographic changes of associated fauna. The analysis of temporal concordance of demographic changes can be used to test the influence of Quaternary climate on diversification processes. Hierarchical approximate Bayesian computation (hABC) is a powerful and flexible approach that models genetic data from multiple species, and can be used to estimate the temporal concordance of demographic processes. Using available single-locus data, we can now perform large-scale analyses, both in terms of number of species and geographic scope. Here, we first compared the power of four alternative hABC models for a collection of single-locus data. We found that the model incorporating an a priori hypothesis about the timing of simultaneous demographic change had the best performance. Second, we applied the hABC models to a data set of seven squamate and four amphibian species occurring in the Seasonally Dry Tropical Forests (Caatinga) in northeastern Brazil, which, according to paleoclimatic evidence, experienced an increase in aridity during the Pleistocene. If this increase was important for the diversification of associated xeric-adapted species, simultaneous population expansions should be evident at the community level. We found a strong signal of synchronous population expansion in the Late Pleistocene, supporting the increase of the Caatinga during this time. This expansion likely enhanced the formation of communities adapted to high aridity and seasonality and caused regional extirpation of taxa adapted to wet forest. © 2017 John Wiley & Sons Ltd.

  5. Demographic Changes and Their Spatial-Settlement Consequences: Lessons from East Germany and Hungary

    Directory of Open Access Journals (Sweden)

    Tibor Kovács


    Full Text Available Demographic shrinkage has created ‘new’ challenges in the spatial and urban development of the developed world and its semi periphery for nearly three and a half decades and it requires a different way of thinking and different solutions as well compared to previous development practices. Theoretical research and development activities in practice are further aggravated by the mono-minded mentality of society, economy and politics fallen a victim to charms of ‘growth’; the slow recognition of the fact of spatial-urban shrinkage and the reluctance to deal with the problem (especially on the semi periphery. In this paper I would like to outline the settlement and spatial problems of demographic shrinkage and suggest certain theoretical solutions being aware of the fact that there is no universal solution for shrinkage; each and every settlement has to find and carry out their own solution – emphasising the mobilisation of the endogenous resources of the given region or settlement.

  9. The advantages of demographic change after the wave: fewer and older, but healthier, greener, and more productive?

    Directory of Open Access Journals (Sweden)

    Fanny Kluge

    Full Text Available Population aging is an inevitable global demographic process. Most of the literature on the consequences of demographic change focuses on the economic and societal challenges that we will face as people live longer and have fewer children. In this paper, we (a briefly describe key trends and projections of the magnitude and speed of population aging; (b discuss the economic, social, and environmental consequences of population aging; and (c investigate some of the opportunities that aging societies create. We use Germany as a case study. However, the general insights that we obtain can be generalized to other developed countries. We argue that there may be positive unintended side effects of population aging that can be leveraged to address pressing environmental problems and issues of gender inequality and intergenerational ties.

  11. Analysing Changes in Discursive Constructions of Rural Areas in the Context of Demographic Change. Towards Counterpoints in the Dominant Discourse on “Dying Villages”

    Directory of Open Access Journals (Sweden)

    Gabriela B. Christmann


    For the conceptualisation of the empirical observations, the article is based on the assumption that it is in communications and in public discourses – in particular specific recurrent contents on rural areas and demographic change – that specific knowledge elements and reality constructions of rural areas emerge and stabilise within society. This assumption includes the idea that when the content of public discourses on rural areas change, for example through small-scale discursive counterpoints, it is possible for new knowledge elements and new constructions of reality to develop. Against this background, the approach of a (new discursive construction of spaces is selected as theoretical starting point for the analysis. By referring to the communicative-constructivism approach and by integrating the sociology of knowledge approach to discourse, it is perfectly suited for theoretically spelling out changing discursive constructions of rural areas in the context of demographic change.

  12. Towards thresholds of disaster management performance under demographic change: exploring functional relationships using agent-based modeling

    Directory of Open Access Journals (Sweden)

    G. Dressler


    Full Text Available Effective disaster management is a core feature for the protection of communities against natural disasters such as floods. Disaster management organizations (DMOs are expected to contribute to ensuring this protection. However, what happens when their resources to cope with a flood are at stake or the intensity and frequency of the event exceeds their capacities? Many cities in the Free State of Saxony, Germany, were strongly hit by several floods in the last years and are additionally challenged by demographic change, with an ageing society and out-migration leading to population shrinkage in many parts of Saxony. Disaster management, which is mostly volunteer-based in Germany, is particularly affected by this change, leading to a loss of members. We propose an agent-based simulation model that acts as a "virtual lab" to explore the impact of various changes on disaster management performance. Using different scenarios we examine the impact of changes in personal resources of DMOs, their access to operation relevant information, flood characteristics as well as differences between geographic regions. A loss of DMOs and associated manpower caused by demographic change has the most profound impact on the performance. Especially in rural, upstream regions population decline in combination with very short lead times can put disaster management performance at risk.

  13. Demographic change and income tax revenue in Germany: a microsimulation approach

    Directory of Open Access Journals (Sweden)

    Martin Beznoska


    Full Text Available As a result of high net migration, both Germany’s overall population and its workforce potential are currently growing. However, within a few years this demographic trend will be reversed, leading to a decline in population as a whole and especially in the number of those gainfully employed. In this paper, we use a population projection to apply a static ageing approach to German micro data. Then, we simulate income tax revenue with a microsimulation model for the future population. In 20 years’ time the annual price-adjusted income tax loss is estimated to be equal to € 18 billion or almost 7 per cent. This fall in income tax revenue resulting from a shrinking and ageing society will place a huge strain on public finances in Germany, an effect further enhanced by the shift of the tax burden from pension contributions to pension benefits.

  14. Academic and Socio-demographic Causes of Medical Student's underachievement in Iranian Medical Schools: A Systematic Review

    Directory of Open Access Journals (Sweden)

    Keivan Dolati


    Full Text Available The academic performance of medical students seems to influence and be influenced by various factors. Identification of the factors that would influence the academic performance may help to modify some of these factors which may be reflecting positively on student’s GPA. Therefore, the objective of present study was to examine the effects of factors such as the student’s demographic data, educational and socio-cultural factors on the academic underachievement of Iranian medical students. In this systematic review study, all the papers related to the investigation of the causes of academic underachievement in case of the Iranian medical students, that were published during the period between 1996 and 2015, were recorded and reviewed. To carry out this purpose, all the Iranian journals and some of the scientific databases such as IranMedex, SID, Magiran, and MedLib, and foreign databases such as PubMed, Web of Science, Google Scholar, ERIC, and Science Direct, were used to search the keywords academic underachievement, medical students, educational status, and education progress. After searching mentioned databases, 218 papers were recorded, 97 of which were unrelated and were omitted during the initial review. After omitting the unrelated papers, 121 papers were reviewed by authors independently, and after the omission of the papers not possessing the criteria to enter the study, 65 papers remained, and finally, after complete reviewing procedure, 10 studies entered the analysis. In conclusion, being married, having second jobs, residing in a dormitory, admission to university by the privilege, low educational level of the parents, long interval between receiving diploma and entering university, male sex, age, not having educational planning and motivation skills, and absence from the classes are the main educational barriers among medical students resulted in underachievement.

    Sharif, H. O.; Joseph, J.; Mullendore, G. L.


    The University of Texas at San Antonio (UTSA), San Antonio College (SAC), and the University of North Dakota (UND) have partnered with NASA to provide underrepresented undergraduates from UTSA, SAC, and other community colleges climate-related research and education experiences through the Climate Change Communication: Engineer, Environmental science, and Education (C3E3) project. The program aims to develop a robust response to climate change by providing K-16 climate change education; enhance the effectiveness of K-16 education particularly in engineering and other STEM disciplines by use of new instructional technologies; increase the enrollment in engineering programs and the number of engineering degrees awarded by showing engineering's usefulness in relation to the much-discussed contemporary issue of climate change; increase persistence in STEM degrees by providing student research opportunities; and increase the ethnic diversity of those receiving engineering degrees and help ensure an ethnically diverse response to climate change. Students participated in the second summer internship funded by the project. The program is in its third year. More than 75 students participated in a guided research experiences aligned with NASA Science Plan objectives for climate and Earth system science and the educational objectives of the three institutions. The students went through training in modern media technology (webcasts), and in using this technology to communicate the information on climate change to others, especially high school students, culminating in production of webcasts on investigating the aspects of climate change using NASA data. Content developed is leveraged by NASA Earth observation data and NASA Earth system models and tools. Three Colleges were involved in the program: Engineering, Education, and Science.

  17. Demographic changes and marker properties affect detection of human population differentiation

    Directory of Open Access Journals (Sweden)

    Sanichwankul Kittipong


    Full Text Available Abstract Background Differentiating genetically between populations is valuable for admixture and population stratification detection and in understanding population history. This is easy to achieve for major continental populations, but not for closely related populations. It has been claimed that a large marker panel is necessary to reliably distinguish populations within a continent. We investigated whether empirical genetic differentiation could be accomplished efficiently among three Asian populations (Hmong, Thai, and Chinese using a small set of highly variable markers (15 tetranucleotide and 17 dinucleotide repeats. Results Hmong could be differentiated from Thai and Chinese based on multi-locus genotypes, but Thai and Chinese were indistinguishable from each other. We found significant evidence for a recent population bottleneck followed by expansion in the Hmong that was not present in the Thai or Chinese. Tetranucleotide repeats were less useful than dinucleotide repeat markers in distinguishing between major continental populations (Asian, European, and African while both successfully distinguished Hmong from Thai and Chinese. Conclusion Demographic history contributes significantly to robust detection of intracontinental population structure. Populations having experienced a rapid size reduction may be reliably distinguished as a result of a genetic drift -driven redistribution of population allele frequencies. Tetranucleotide markers, which differ from dinucleotide markers in mutation mechanism and rate, are similar in information content to dinucleotide markers in this situation. These factors should be considered when identifying populations suitable for gene mapping studies and when interpreting interpopulation relationships based on microsatellite markers.

  18. Demographic, socioeconomic and environmental changes affecting circulation of neglected tropical diseases in Egypt. (United States)

    Abou-El-Naga, Iman F


    Egypt has been plagued by many neglected tropical diseases since Pharaonic time. These diseases are Schistosomiasis, soil-transmitted helminthiasis, lymphatic filariasis, leishmaniasis and fascioliasis beside the epidermal parasitic skin diseases. Indeed, theses diseases still persist as public health problem in the country by the influence of demographic, socioeconomic and environmental obstacles. This study seeks for understanding the contribution of each factor in each obstacle in neglected tropical diseases perpetuation which in turn could help the governorate in planning integrated control strategies. It was found that poverty, unregulated urbanization and inadequate sanitation are important socioeconomic factors that have great effect on the transmission dynamics of the diseases. The environmental factors which affect the epidemiology of these diseases in the country are scarcity of water, construction of dams, land reclamation for agriculture beside the climate factors. Unfortunately, the panic increase in the population growth rate minimizes the efforts done by the governorate to elevate the public health services. These conditions also affect the transmission of epidermal parasitic skin diseases including scabies, head lice and hookworm-related cutaneous larva migrans. The control programs and the recommendations to combat the diseases were discussed. The present study showed that the ecological factors affecting each neglected tropical disease in Egypt are somewhat similar which makes it worthy to develop an integrated control approaches aiming at improving the leading factors of neglected tropical diseases circulation in the country.

  19. The changing motivation of massage therapy students. (United States)

    Finch, P


    The study was conducted in order to determine whether the level of motivation related to intrinsic (people-oriented) and extrinsic (external reward) value complexes in a class of massage therapy students changed during their professional education. The research was a quasi-experimental within-subject design, in which survey data was collected from students on their first day in the massage therapy program and again towards the end of their final term. The data were collated and summarized, and the differences in motivation scores were assessed using Fisher's Least Significant Difference procedure. The results support the hypothesis that massage therapy students are motivated more strongly by intrinsic than extrinsic rewards both at the commencement of their studies and as they approach entry to practice. Also evident from the data is the fact that the students' motivation changed during their professional studies. This change involved a significant decrease in the level of intrinsic motivation and significant increase in the level of extrinsic motivation. Thus, although intrinsic motivation reduced while extrinsic motivation increased, the former remained the more powerful influence. Professional programs should consider the balance between intrinsic and extrinsic student motivation and attempt to control influences that might shift this such that the humanistic / altruistic mission of health care is undermined.

    Vukoičić Danijela


    Full Text Available The settlements along the administrative line in Serbia towards Kosovo and Metohija had a very turbulent demographic changes in the past. These changes have influenced the present. In this paper we investigated the depopulation process of this area which is intensified with the political instability, social and economic changes. The main goal of this research was to analyze the causes and effects in the reduction of the number of inhabitants, as well as the possibility of revitalizing the rural settlements of a given area. To obtain the desired results, we analyzed the existing literature and statistical data, used comparative and historical methods as well as implemented the field surveys. The application of the SWOT analysis to the researched area have showed us the strength, weakness, opportunities, and threats that can effect the process of revitalization of the village.

  3. Baby Booming Inequality? Demographic Change and Inequality in Norway, 1967{2004.


    Almås, Ingvild; Havnes, Tarjei; Mogstad, Magne


    We demonstrate how age-adjusted inequality measures can be used to evaluate whether changes in inequality over time are because of changes in the age structure. In particular, we explore the hypothesis that the substantial rise in earnings inequality since the early 1980s is driven by the large baby boom cohorts approaching the peak of the age-earnings profile. Using administrative data on earnings for every Norwegian male over the period 1967-2004, we find that the impact of age ...

  4. Added value from European Territorial Co-operation: the impact of demographic change in the Alps on the young

    Directory of Open Access Journals (Sweden)

    Marot Naja


    Full Text Available The article sets demographic change in the Alps in the framework of European Territorial Cooperation programs. A statistical overview of selected regions in five Alpine countries serves as a basis for further policy analysis. The latter was undertaken to reveal how transnational projects tackle youth issues, including the difficulties within the labour and real estate markets that appeared to be the most problematic factors influencing (out migration of the youth. While there is only a minor recognition of the young in current policymaking on supranational, regional and local levels, the analysis showed that the added value of transnational programs for mountain regions and localities can be recognized in the development of multi-stakeholder environments, creating and transferring new solutions for the labour market as well as empowering youth participation in policy processes. However, the extent to which these solutions might contribute to overcoming the challenges of demographic change because of transnational programs is limited by various factors. Among these are the precise governance framework, administrative capacity, and population figures.

    Xiang, Y-T; Wang, C-Y; Ungvari, G S; Kreyenbuhl, J A; Chiu, H F K; Lai, K Y C; Lee, E H M; Bo, Q-J; Dixon, L B


    This study aimed to characterize weight changes in schizophrenia patients taking risperidone as part of a randomized, controlled, open-label clinical trial. A total of 374 patients with schizophrenia who had been clinically stabilized following an acute episode were randomly assigned to a 'no-dose-reduction' group (initial optimal therapeutic doses continued throughout the study), a '4-week group' (initial optimal therapeutic doses continued for 4 weeks followed by a half dose reduction that was maintained until the end of the study) or a '26-week group' (initial optimal therapeutic doses continued for 26 weeks followed by a half dose reduction until the end of the study). Participants were assessed monthly using standardized assessment instruments during the first 6 months, and then every 2 months until the last recruited patient completed the 1-year follow-up. Weight gain was defined as gaining at least 7% of initial body weight, weight loss as losing at least 7% of initial body weight. A BMI weight loss compared to being normal weight. No correlation was found between weight change and dose reduction. Weight change is a common, long-term, but heterogeneous side effect in risperidone maintenance treatment for stable schizophrenia patients. Special attention should be paid to fluctuations in weight that may occur throughout the course of treatment with risperidone. © Georg Thieme Verlag KG Stuttgart · New York.

  8. The influence of a demographic change on social relationships among male golden snub-nosed monkeys (Rhinopithecus roxellana). (United States)

    Huang, Pengzhen; Zhang, Endi; Chen, Min


    It has been suggested that social relationships are more likely to be prone to variation in the dispersing sex than the philopatric sex. However, we know less about the dynamics of all-male groups in male-dispersing species than we do about other types of primate groups. We studied male sociality in a captive group of golden snub-nosed monkeys (Rhinopithecus roxellana), which was composed of a one-male unit (OMU, N = 7) and an all-male unit (AMU, N = 7 or 8), in Shanghai Wild Animal Park, China. Using data collected for 6 months, during which there was a demographic change in the AMU and the alpha male was replaced by a newcomer, we found that a dramatic change in social ranks occurred accompanied by elevated aggression following this social upheaval. A proximity-based social network analysis revealed that members did not associate randomly any more but formed differentiated relationships post-upheaval, resulting in three distinct sub-units in the AMU. In terms of inter-unit interactions, significant changes were found in the affiliations between the male juvenile of OMU and AMU individuals. He interacted with AMU individuals randomly and frequently pre-upheaval, but cut down his affiliations and had a preferred partner post-upheaval, who was a member of the dominant male's sub-unit. Our findings suggest that social networks in the dispersing sex are dynamic structures and vary by some demographic change (e.g., individual immigration) in the studied species. We also put forward that individual dominance could be a criterion when the male juvenile chooses partners before he immigrates into a group. In conclusion, the high level of behavioral flexibility of the dispersing sex could be an evolutional strategy and good for individuals' future dispersing life.

  9. Changing demographics of spinal cord injury over a 20-year period: a longitudinal population-based study in Scotland. (United States)

    McCaughey, E J; Purcell, M; McLean, A N; Fraser, M H; Bewick, A; Borotkanics, R J; Allan, D B


    A retrospective cohort study. To review demographic trends in traumatic spinal cord injury (TSCI) and non-traumatic spinal cord injury (NTSCI). The Queen Elizabeth National Spinal Injuries Unit (QENSIU), sole provider of treatment for TSCI in Scotland; a devolved region of the UK National Health Service. A retrospective review of the QENSIU database was performed between 1994 and 2013. This database includes demographic and clinical data from all new TSCI patients in Scotland, as well as patients with severe NTSCI. Over this 20-year period there were 1638 new cases of TSCI in Scotland; 75.2% occurring in males. TSCI incidence increased non-significantly (13.3 per million population to 17.0), while there were significant increases in mean age at time of TSCI (44.1-52.6 years), the proportion of TSCIs caused by falls (41-60%), the proportion of TSCIs resulting in an American Spinal Injury Association Impairment Scale score of C and D on admission (19.7-28.6% and 34.5-39.5%, respectively) and the proportion of cervical TSCIs (58.4-66.3%). The increase in cervical TSCI was specifically due to an increase in C1-C4 lesions (21.7-31.2%). NTSCI patients (n=292) were 5 years older at injury, more likely to be female (68.1% male) and had a range of diagnoses. This study supports the suggestion that demographic profiles in SCI are subject to change. In this population, of particular concern is the increasing number of older patients and those with high level tetraplegia, due to their increased care needs. Prevention programmes, treatment pathways and service provision need to be adjusted for optimum impact, improved outcome and long-term care for their target population.

Analysis of the population dynamics and changes in the share of arable land in the structure of land use separate territory for several historical periods, and to determine the causes of these changes. Methods. Studies have used forwarding, statistical methods, and the method of cartographic modeling and retrospective analysis. Results. Analysis of the results of the population census allows speaking about the general negative dynamics in the rural population of the Volgograd region in general and river basin Bolshaya Golubaya in particular. Historical and cartographic analysis has shown the dependence of the arable lands of the number of residents on the territory residents. In addition, the population of the territory is significantly affected by soil fertility. Main conclusions. The population of the river basin Bolshaya Golubaya over the past hundred years have steadily decreased, as due to various socio-economic reasons, such as consolidation of rural settlements, the planned destruction of farm system, moving people into the city, and due to the difficult climatic conditions for farming: poor soil fertility, high degree of erosion areas, poor soil conditions of the territory.

  11. Mapping sleeping sickness in Western Africa in a context of demographic transition and climate change

    Directory of Open Access Journals (Sweden)

    Cecchi G.


    Full Text Available Human population growth, climate change and economic development are causing major environmental modifications in Western Africa, which will have important repercussions on the epidemiology of sleeping sickness. A new initiative, the Atlas of human African trypanosomiasis (HAT, aims at assembling and geo-referencing all epidemiological data derived from both active screening activities and passive surveillance. A geographic database enables to generate up-to-date disease maps at a range of scales and of unprecedented spatial accuracy. We present preliminary results for seven West African countries (Benin, Burkina Faso, Côte d’Ivoire, Ghana, Guinea, Mali and Togo and briefly discuss the relevance of the Atlas for future monitoring, control and research activities.

  12. Empirical study on impact of demographic and economic changes on pension cost (United States)

    Yusof, Shaira; Ibrahim, Rose Irnawaty


    A continuation of the same financial standard of living after retirement as before is very importance to retired person. The pension provider has a responsibility to ensure their employees receive the sufficient benefit after retirement and regularly monitor the factors that cause insufficient funds to pay benefit to retirees. Insufficient funds may be due to increased in pension cost. Some of the factors that increase the cost of pensions are changes in mortality rates and interest rates. This study will used these two factors to determine their sensitivity to pension cost. Two methods which are Accrued Benefit Cost Method and Projected Benefit Cost Method will be used to estimate pension cost. Interest rates has a inversely related to pension cost while mortality rates has a directly related to pension cost.

  13. Historical, Demographic, and Economic Correlates of Land-Use Change in the Republic of Panama

    Directory of Open Access Journals (Sweden)

    Stuart Joseph. Wright


    Full Text Available The Republic of Panama recently experienced a limited forest transition. After five decades of decline, the total forest cover increased by 0.36% yr-1 between 1992 and 2000; however, mature forest cover simultaneously decreased by 1.3% yr-1. This limited forest transition at the national scale comprised two distinctly different patterns of recent forest-cover change related to historical land use. Districts that were largely deforested when the first national survey of forest cover was completed in 1947 experienced a strong forest transition between 1992 and 2000. In these, the proportion of the population employed in agriculture decreased by an average of 31% and natural secondary forest succession increased the total forest cover by an average of 85% between 1992 and 2000. In contrast, no forest transition was evident for districts that were largely forested in 1947. In these, the absolute number of people employed in agriculture remained constant, old-growth forest cover decreased by 8% on average, and natural secondary forest succession increased, so that the total forest cover tended to be static between 1992 and 2000. Historical land use, an index of human poverty, and the population density of agricultural workers explained 61% of the among-district variation in forest cover in 2000, with forest concentrated in areas where populations were small and poor. Historical land use and gross income per hectare from agriculture explained 23.5% of the among-district variation in forest-cover change between 1992 and 2000. The early history of forest loss, an uneven distribution of people, and disparities in farm income contributed to the limited forest transition observed in Panama.

  16. A decomposition analysis of change in skilled birth attendants, 2003 to 2008, Ghana Demographic and Health Surveys. (United States)

    Bosomprah, Samuel; Aryeetey, Genevieve Cecelia; Nonvignon, Justice; Adanu, Richard M


    The single most critical intervention to improve maternal and neonatal survival is to ensure that a competent health worker with midwifery skills is present at every birth, and transport is available to a referral facility for obstetric care in case of an emergency. This study aims to describe changes in percentage of skilled birth attendants in Ghana and to identify causes of the observed changes as well as the contribution of different categories of mother's characteristics to these changes. This study uses two successive nationally representative household surveys: the 2003 and 2008 Ghana Demographic and Health Surveys (GDHS). The two datasets have comparable information on household characteristics and skilled attendants at birth at the time of the survey. The 2003 GDHS database includes information on 6,251 households and 3639 live births in the five years preceding the survey, whereas the 2008 GDHS database had information on11, 778 households and 2909 live births in the five years preceding the survey. A decomposition approach was used to explain the observed change in percentage of skilled birth attendants. Random-effects generalized least square regression was used to explore the effect of changes in population structure in respect of the mother's characteristics on percentage of skilled birth attendants over the period. Overall, the data showed absolute gain in the proportion of births attended by a health professional from 47.1% in 2003 to 58.7% in 2008, which represents 21.9% of gap closed to reach universal coverage. The increase in skilled birth attendants was found to be caused by changes in general health behaviour. The gain is regardless of the mother's characteristics. The structural change in the proportion of births in respect of birth order and mother's education had little effect on the change in percentage of skilled birth attendants. Improvement in general health behaviour can potentially contribute to an accelerated increase in proportion

    In order to study the effects of progress in industrialization and urbanization on societies and economy, analyses were performed on the northern England in the period of the Industrial Revolution. The rapid expansion of the city of Leeds in the 1780`s and on had brought about the increase in employment opportunities in the suburban farming villages, as well as drop in matrimonial age in agricultural and coal mine workers, and the rapid population increase. Housing conditions for those workers who had flown into the city from agricultural villages in a large number were of very poor quality, and their living standard was low. More than half of the patients visiting the charity hospital in Leeds City came from the urban area, with industrial accidents such as injuries in young workers noticed remarkably high. Many women were included in them, from which the progress in mechanization of the textile industry in Leeds and its surrounding areas can well be imagined. The attributes of households, families, and population were divided into diverse structures and hierarchies, according to the residential construction form and work income earner rates in family constituting members were also various. The development urbanization and industrialization had given diversified effects on households, families, population, and life cycles in city dwellers through changes in housing environments. 2 refs., 1 fig., 7 tabs.

    Full Text Available Livestock population and its structure is the starting point for all development strategies at both micro and macro level, reason for which accurate knowledge of it is one of the main objectives of official statistics in each state. The analysis aims to highlight the major changes produced after the 90s in terms of population of Bacău county and its structure, with time effects on economic and social activity. Both the 2002 and 2011 census, Bacău was top of the list with an absolute decrease of the population. This was a concern as it has emerged over time as a stable phenomenon. The main reason for the decrease was due to external migration of the population and secondly because of the internal migration flows of population moving towards large economic centers in the country and abroad that attract labor. As most of the migrants are young and active age groups, this phenomena has led to an aging population and to imbalances that can be observed in the age pyramid, with negative effects becoming larger in the future.

  19. An assessment of the impact of demographic, cognitive, and non-cognitive variables on student success in a community college science course (United States)

    Mackey, Audrey Leroy

    The impact of demographic, cognitive, and non-cognitive variables on academic success among community college science students was studied. Demographic variables included gender, employment status, and ethnicity. Cognitive variables included college grade point average, assessment status, course prerequisites, college course success ratios, final course grade, withdrawal patterns, and curriculum format. Non-cognitive variables included enrollment status, educational objectives, academic expectations, and career goals. The sample population included students enrolled in human anatomy courses (N = 191) at a large metropolitan community college located in central Texas. Variables that potentially influence attrition and achievement in college level science courses were examined. Final course grade and withdrawal phenomena were treated as dependent variables, while all other variables were treated as independent variables. No significant differences were found to exist between any of the demographic variables studied and the numbers of students who withdrew passing or failing. A difference was shown to be associated with the ethnicity variable and achievement levels. Educational objectives and career goals were shown to have an impact on the number of students who withdrew failing. The career goals variable and the academic expectations variable were shown to have an impact on achievement among daytime and evening students. College grade point average and course success ratios were shown to make a difference among students who withdrew passing. None of the other cognitive variables studied were shown to influence the numbers of students who withdrew passing or failing. College grade point average and course prerequisites, however, were shown to make a difference in achievement. The collaborative learning instructional format was found to have no impact on attrition or achievement, however, mean scores earned by students experiencing the collaborative learning format

  20. Analyses of Student Learning in Global Change (United States)

    Takle, E. S.; Moser, H.; Sorensen, E. K.


    The Global Change course at Iowa State University is a senior undergraduate and graduate level course that has been delivered over the internet with online dialog and learning activities since 1995. Students may enroll in the course as a distance education course, but in doing so they engage in dialog with students in the conventional on-campus face-to-face course. Online delivery and student participation offer opportunities for promoting use of critical thinking skills and collaborative learning not available in face-to-face environments. Students are required to research, post, and defend with authoritative information their positions on a variety of global change issues and specifically identify how they have demonstrated use of critical thinking skills in their online postings. Threaded dialog is used for structuring interactions toward promoting collaborative learning. We analyze collaborative learning by use of a rubric based on the theory of language games. By random selection of 1,350 online dialog comments posted over the last 10 years we evaluated student response to requirements for demonstrating critical thinking skills and collaboration in learning. We found that, by itself, the requirement of demonstrating critical thinking skills in online dialog was insufficient in promoting collaborative learned as measured by the standards of language game theory. But we also found that if an online comment clearly defines a situation and makes a clear expectation of a response, the likelihood is high that a game will be created. And if a game is established, there is a high probability that it will be closed, thereby giving evidence that collaborative learning had occurred. We conclude that a key component in collaborative online learning lies in establishing a lead-off comment that provides sufficient background information to clearly define an engaging situation. It also must include a clear expectation that a response is expected that will provide dialog

  1. Polar and brown bear genomes reveal ancient admixture and demographic footprints of past climate change (United States)

    Miller, Webb; Schuster, Stephan C.; Welch, Andreanna J.; Ratan, Aakrosh; Bedoya-Reina, Oscar C.; Zhao, Fangqing; Kim, Hie Lim; Burhans, Richard C.; Drautz, Daniela I.; Wittekindt, Nicola E.; Tomsho, Lynn P.; Ibarra-Laclette, Enrique; Herrera-Estrella, Luis; Peacock, Elizabeth; Farley, Sean; Sage, George K.; Rode, Karyn D.; Obbard, Martyn E.; Montiel, Rafael; Bachmann, Lutz; Ingólfsson, Ólafur; Aars, Jon; Mailund, Thomas; Wiig, Øystein; Talbot, Sandra L.; Lindqvist, Charlotte


    Polar bears (PBs) are superbly adapted to the extreme Arctic environment and have become emblematic of the threat to biodiversity from global climate change. Their divergence from the lower-latitude brown bear provides a textbook example of rapid evolution of distinct phenotypes. However, limited mitochondrial and nuclear DNA evidence conflicts in the timing of PB origin as well as placement of the species within versus sister to the brown bear lineage. We gathered extensive genomic sequence data from contemporary polar, brown, and American black bear samples, in addition to a 130,000- to 110,000-y old PB, to examine this problem from a genome-wide perspective. Nuclear DNA markers reflect a species tree consistent with expectation, showing polar and brown bears to be sister species. However, for the enigmatic brown bears native to Alaska's Alexander Archipelago, we estimate that not only their mitochondrial genome, but also 5–10% of their nuclear genome, is most closely related to PBs, indicating ancient admixture between the two species. Explicit admixture analyses are consistent with ancient splits among PBs, brown bears and black bears that were later followed by occasional admixture. We also provide paleodemographic estimates that suggest bear evolution has tracked key climate events, and that PB in particular experienced a prolonged and dramatic decline in its effective population size during the last ca. 500,000 years. We demonstrate that brown bears and PBs have had sufficiently independent evolutionary histories over the last 4–5 million years to leave imprints in the PB nuclear genome that likely are associated with ecological adaptation to the Arctic environment.

  3. Use of non-steroidal anti-inflammatory drugs in US adults: changes over time and by demographic. (United States)

    Davis, Jennifer S; Lee, Hwa Young; Kim, Jihye; Advani, Shailesh M; Peng, Ho-Lan; Banfield, Emilyn; Hawk, Ernest T; Chang, Shine; Frazier-Wood, Alexis C


    Aspirin and non-aspirin non-steroidal anti-inflammatory drugs (NSAIDs) are preventive against cardiovascular disease (CVD) and several cancer types, but long-term use has been associated with significant health risks, resulting in conflicting recommendations on NSAID use for prevention of CVD and cancer. Previous research indicates that aspirin use increases with age and CVD risk factors and that a large percentage of the US population regularly use analgesics, including NSAIDs, but there has not been a recent, in-depth assessment of NSAID use prevalence, changes in use over time or predictors of NSAID use in the USA. We used the cross-sectional, National Health And Nutrition Examination Survey (NHANES) from 1988 to 1994 and three continuous cycles (1999-2004) to assess regular NSAID use prevalence, changes over time and predictors of regular NSAID use. Overall, regular NSAID use increased over time and varied by demographic features. Participants over 60 years of age, women, participants with high body mass index, increased waist circumference or heart disease were significantly more likely to be regular NSAID users. By contrast, non-Hispanic African American and Mexican American participants were significantly less likely to regularly use NSAIDs. This study uses a nationally representative data set (NHANES) to provide an exploration of regular NSAID use patterns over time, highlighting several demographic, lifestyle and clinical conditions associated with regular NSAID use. Understanding who is likely to regularly use NSAIDs enables more targeted messaging both for increasing the preventive benefits and for limiting the toxicities associated with regular use of NSAIDs.

  4. Socio-demographic predictors of health and environmental co-benefit behaviours for climate change mitigation in urban China. (United States)

    This study aims to examine the patterns and socio-demographic predictors of health and environmental co-benefit behaviours that support climate change mitigation in a densely populated Asian metropolis-Hong Kong. A population-based, stratified and cross-sectional random digit dialling telephone survey study was conducted between January and February 2016, among the Cantonese-speaking population aged 15 and above in Hong Kong. Socio-demographic data and the self-reported practice of 10 different co-benefit behaviours were solicited. Ethics approval and participant's verbal consent were sought. The study sample consisted of 1,017 respondents (response rate: 63.6%) were comparable to the age, gender and geographical distributions of the Hong Kong population found in the latest 2011 Hong Kong Population Census. Among the co-benefit behaviours, using less packaging and disposable shopping bags were practiced in the highest frequency (70.1%). However, four behaviours were found to have never been practiced by more than half of the respondents, including bringing personal eating utensils when dining in restaurants or small eateries, showering less than five minutes, having one vegetarian meal a week, and buying more organic food. Results of multivariable logistic regression showed that frequency of practicing co-benefit behaviours were consistently associated with gender and age. Urban residents in Hong Kong do not engage in the practice of co-benefit behaviours in a uniform way. In general, females and older people are more likely to adopt co-benefit behaviours in their daily lives. Further research to assess the knowledge and attitudes of the population towards these co-benefit behaviours will provide support to relevant climate change mitigation policies and education programmes.

  5. Securing the Continuity of Medical Competence in Times of Demographic Change: A Proposal. (United States)

    Hasebrook, Joachim Paul; Hinkelmann, Jürgen; Volkert, Thomas; Rodde, Sibyll; Hahnenkamp, Klaus


    University hospitals make up the backbone of medical and economic services of hospitals in Germany: they qualify specialist physicians, ensure medical research, and provide highly specialized maximum medical care, which other hospitals cannot undertake. In addition to this assignment, medical research and academic teaching must be managed despite a growing shortage of specialist physicians. By the year 2020, the need for the replacement of retired physicians and increased demand will total 30,000 positions. The situation will become more difficult because, on the whole, patients are becoming older and sicker and because specialist physicians are able to find more attractive working conditions in smaller hospitals, abroad, or outside of curative medicine. In order to retain sufficient qualified employees, major improvements in quality are required in terms of working and training conditions. For this purpose, a sustainable innovation process is necessary, which incorporates solutions from outside of the health care sector in order to be able to learn from experiences and mistakes from other industries. The FacharztPlus project aims to find suitable measures in order to retain specialist physicians for more years after the completion of 5 years of professional training. This should determine the suitability of additional qualifications alongside the professional career and an expertise-related work organization oriented to different stages of life. Structured interviews, surveys, and repertory grids are used as preparation for cross-industry expert panels to create future work scenarios for university hospitals. Industries involved are harbor logistics (container terminal), airports, and digitized industrial production ("industry 4.0") because these industries are also facing a shortage of qualified staff and have to respond to rapidly changing demands. Based on the experts' scenarios, consensus groups will be established in each university hospital trying to reach

  7. The future demographic niche of a declining grassland bird fails to shift poleward in response to climate change (United States)

    McCauley, Lisa A.; Ribic, Christine; Pomara, Lars Y.; Zuckerberg, Benjamin


    ContextTemperate grasslands and their dependent species are exposed to high variability in weather and climate due to the lack of natural buffers such as forests. Grassland birds are particularly vulnerable to this variability, yet have failed to shift poleward in response to recent climate change like other bird species in North America. However, there have been few studies examining the effect of weather on grassland bird demography and consequent influence of climate change on population persistence and distributional shifts.ObjectivesThe goal of this study was to estimate the vulnerability of Henslow’s Sparrow (Ammodramus henslowii), an obligate grassland bird that has been declining throughout much of its range, to past and future climatic variability.MethodsWe conducted a demographic meta-analysis from published studies and quantified the relationship between nest success rates and variability in breeding season climate. We projected the climate-demography relationships spatially, throughout the breeding range, and temporally, from 1981 to 2050. These projections were used to evaluate population dynamics by implementing a spatially explicit population model.ResultsWe uncovered a climate-demography linkage for Henslow’s Sparrow with summer precipitation, and to a lesser degree, temperature positively affecting nest success. We found that future climatic conditions—primarily changes in precipitation—will likely contribute to reduced population persistence and a southwestward range contraction.ConclusionsFuture distributional shifts in response to climate change may not always be poleward and assessing projected changes in precipitation is critical for grassland bird conservation and climate change adaptation.

  8. Demographic consequences of climate change and land cover help explain a history of extirpations and range contraction in a declining snake species. (United States)

    Pomara, Lars Y; LeDee, Olivia E; Martin, Karl J; Zuckerberg, Benjamin


    Developing conservation strategies for threatened species increasingly requires understanding vulnerabilities to climate change, in terms of both demographic sensitivities to climatic and other environmental factors, and exposure to variability in those factors over time and space. We conducted a range-wide, spatially explicit climate change vulnerability assessment for Eastern Massasauga (Sistrurus catenatus), a declining endemic species in a region showing strong environmental change. Using active season and winter adult survival estimates derived from 17 data sets throughout the species' range, we identified demographic sensitivities to winter drought, maximum precipitation during the summer, and the proportion of the surrounding landscape dominated by agricultural and urban land cover. Each of these factors was negatively associated with active season adult survival rates in binomial generalized linear models. We then used these relationships to back-cast adult survival with dynamic climate variables from 1950 to 2008 using spatially explicit demographic models. Demographic models for 189 population locations predicted known extant and extirpated populations well (AUC = 0.75), and models based on climate and land cover variables were superior to models incorporating either of those effects independently. These results suggest that increasing frequencies and severities of extreme events, including drought and flooding, have been important drivers of the long-term spatiotemporal variation in a demographic rate. We provide evidence that this variation reflects nonadaptive sensitivity to climatic stressors, which are contributing to long-term demographic decline and range contraction for a species of high-conservation concern. Range-wide demographic modeling facilitated an understanding of spatial shifts in climatic suitability and exposure, allowing the identification of important climate refugia for a dispersal-limited species.

  9. Double Exposure and the Climate Gap: Changing demographics and extreme heat in Ciudad Juárez, Mexico (United States)

    Collins, Timothy W.; McDonald, Yolanda J.; Aldouri, Raed; Aboargob, Faraj; Eldeb, Abdelatif; Aguilar, María de Lourdes Romo; Velázquez-Angulo, Juárez Gilberto


    Scholars have recognized a climate gap, wherein poor communities face disproportionate impacts of climate change. Others have noted that climate change and economic globalization may mutually affect a region or social group, leading to double exposure. This paper investigates how current and changing patterns of neighborhood demographics are associated with extreme heat in the border city of Juárez, Mexico. Many Juárez neighborhoods are at-risk to triple exposures, in which residents suffer due to the conjoined effects of the global recession, drug war violence, and extreme heat. Due to impacts of the recession on maquiladora employment and the explosion of drug violence (since 2008), over 75% of neighborhoods experienced decreasing population density between 2000 and 2010 and the average neighborhood saw a 40% increase in the proportion of older adults. Neighborhoods with greater drops in population density and increases in the proportion of older residents over the decade are at significantly higher risk to extreme heat, as are neighborhoods with lower population density and lower levels of education. In this context, triple exposures are associated with a climate gap that most endangers lower socioeconomic status and increasingly older aged populations remaining in neighborhoods from which high proportions of residents have departed.

  10. Changes of marital behavior and family patterns in post-socialist countries: Delayed, incomplete or specific second demographic transition?

    Directory of Open Access Journals (Sweden)

    Petrović Mina


    Full Text Available The paper starts by questioning the theory of second demographic transition (SDT and its universal relevance in the field of marriage behavior and family organization in low fertility context, arguing for more differentiated approaches. With an aim to illustrate the contextual specifics of post-socialist countries in general and of Serbia in particular, the author claims that analyzed changes have not just been delayed or incomplete in comparison to more developed European countries, but shaped by specific modernization processes, which led to rationally developed strategies in overcoming structural risks, although, without ideational changes typical to the theory of SDT. Slow changes in marital behavior and family organization in Serbia are illustrated in recent sociological (empirical research findings. The perceived changes are linked to specific structural risks (war, slow transformation and enduring economic hardships, weak state and low trust in institutions, etc and value characteristics (persistence of materialism and traditionalism, but with increasing ambivalence. The connection between structural and ideational changes is considered through social stratification variable by relying on Coale's model on necessary preconditions for behavioral changes as well as on social deprivation concept. Having in mind upper social strata (more educated and better off, the value changes precede the behavioral that are adapted to economic uncertainty, which still force more traditional marital and family patterns. Therefore, there is a rank of different options, from extended family (for a short period at the beginning of marriage or after divorce to separated leaving (of married partners in parental households (due to refusing the extended family option thus creating quite specific "living apart together" form, combined with dominant strategy of prolonging the marriage. Hence, for upper social strata, marriage is still a universal but negotiable

  12. Linking temporal changes in the demographic structure and individual growth to the decline in the population of a tropical fish (United States)

    Sirot, Charlotte; Darnaude, Audrey M.; Guilhaumon, François; Ramos-Miranda, Julia; Flores-Hernandez, Domingo; Panfili, Jacques


    The exceptional biodiversity and productivity of tropical coastal lagoons can only be preserved by identifying the causes for the decline in the populations living in these vulnerable ecosystems. The Terminos lagoon in Mexico provided an opportunity for studying this issue as some of its fish populations, in particular the Silver Perch (Bairdiella chrysoura), have declined significantly since the 1980s. Fish sampling campaigns carried out over the whole lagoon area in 1979-81 and again in 2006-2011 revealed the mechanisms which may have been responsible for this decline. Based on biometrical data for 295 juveniles and adults from the two periods and on somatic growth derived from 173 otoliths, a study of the temporal changes in the demographic structure and life history traits (individual growth and body condition) made it possible to distinguish the causes of the decline in the B. chrysoura population. Growth models for the lagoon in 1980-1981 and 2006-2011 showed no significant change in the growth parameters of the population over the last 30 years with a logistic model giving an accurate estimate (R2 = 0.66) of the size-at-age for both periods. The decline in the B. chrysoura population could not be explained by an overall decrease in individual size and condition in the lagoon, the average standard length (SL) and Fulton index (FI) having increased slightly since 1980-1981 (4.6 mm and 0.02 for juveniles and 5.42 mm and 0.07 for adults). However, the size structure of the population in the lagoon has changed, with a significant shift in the size distribution of juveniles with a marked reduction in the proportion of juveniles ≤ 60 mm in the captures (90.9% fewer than in 1980-1981). As the otolith growth rate of fish during the first 4 months also decreased significantly between the two sampling periods (-15%), it is suggested that the main reason for the decline in the abundance and biomass of B. chrysoura within this system may be that its habitats are less

  13. Socio-Demographic and Lifestyle Factors Predict 5-Year Changes in Adiposity among a Group of Black South African Adults

    Cornelie Nienaber-Rousseau


    Full Text Available The rising prevalence of obesity and excessive adiposity are global public health concerns. Understanding determinants of changes in adiposity over time is critical for informing effective evidence-based prevention or treatment. However, limited information is available to achieve this objective. Cultural, demographic, environmental, and behavioral factors including socio-economic status (SES likely account for obesity development. To this end, we related these variables to anthropometric measures in 1058 black adult Tswana-speaking South Africans who were HIV negative in a prospective study over five years. Body mass index (BMI and waist circumference increased in both sexes, whereas triceps skinfold thickness remained the same. Over the five years, women moved to higher BMI categories and more were diagnosed with central obesity. Age correlated negatively, whereas SES, physical activity, energy, and fat intake correlated positively with adiposity markers in women. In men, SES, marital status, physical activity, and being urban predicted increases in adiposity. For women, SES and urbanicity increased, whereas menopause and smoking decreased adiposity. Among men, smokers had less change in BMI than those that never smoked over five years. Our findings suggest that interventions, focusing on the urban living, the married and those with the highest SES—the high-risk groups identified herein—are of primary importance to contain morbidity and premature mortality due to obesity in black South Africans.

    Ziapour, Arash; Khatony, Alireza; Jafari, Faranak; Kianipour, Neda


    Spiritual well-being is one of the aspects of well-being which organize the physical, psychological, and social aspects. Given the outstanding and unique roles of students in society, providing spiritual well-being as well as identifying and eliminating the negative factors affecting their mental well-being are of the essence. The present study aimed to predict the dimensions of the spiritual well-being of students at Kermanshah University of Medical Sciences and to investigate the roles of demographic variables in this respect. In this descriptive and correlational study, the statistical population was comprised of 346 doctoral students in the for-profit Schools of Medicine, Dentistry and Pharmaceuticals in Kermanshah University of Medical Sciences in 2016. For data collection, an instrument comprising the demographic questions and the 20-item spiritual well-being scale by Paloutzian and Ellison (1982) was utilized. To analyze data, the descriptive (frequency distribution, mean, and standard deviation) and inferential statistics (independent t-test, one-way ANOVA, and chi-squared test) were employed in the SPSS Statistics Software Version 21.0. The results of the present study demonstrated that the spiritual well-being of students was average (71.86±4.84), and of all demographic variables under study, only the variable of gender significantly correlated with the mean score of spiritual well-being. Also, the results revealed that the students' score of religious well-being measured higher than that of their existential well-being. However, a significant correlation was found between spiritual well-being and its dimensions. Also, the religious and existential well-being were found to be significantly related (pspirituality among the students of the for-profit Schools at Kermanshah University of Medical Sciences. Therefore, it is recommended that appropriate plans be laid by the culture and education policy makers to promote the spiritual well-being of university

  15. Do commencing nursing and paramedicine students differ in interprofessional learning and practice attitudes: evaluating course, socio-demographic and individual personality effects. (United States)

    Hallam, Karen T; Livesay, Karen; Morda, Romana; Sharples, Jenny; Jones, Andi; de Courten, Maximilian


    Interprofessional education (IPE) requires health students to learn with, from and about each other in order to develop a modern workforce with client-centred care at its core. Despite the client centred focus of IPE, training programs often utilize standard approaches across student cohorts without consideration of discipline, sociodemographic and personality variability that attract students to different health disciplines. Knowing the students who engage in IPE to tailor training may prove as beneficial as knowing the client to delivered individualized client centred care in interprofessional practice (IPP). This research investigates whether students commencing undergraduate nursing and paramedicine degrees ener training with existing demographic and personality differences and, if these are associated with different attitudes towards health care teams and interprofessional education. This online study recruited 160 nursing and 50 paramedicine students in their first week of their undergraduate course. Students completed questionnaires regarding their background, personality (General Perceived Self Esteem Scale, International Mini Markers) and the attitudes towards health care teams scale (ATHCTS) and interprofessional education perception scale (IEPS). Results show that commencing nursing and paramedicine students are demographically different on education, gender, speaking a language other than English at home (LOTE) and their own experience with healthcare. The results further demonstrate that LOTE, discipline being studied and personality factors play a role in perceptions regarding interprofessional training whilst discipline being studied impacted on attitudes towards health care teams in the workforce. These results highlight a number of existing personal and psychological differences between individuals who choose to train in these selected professions. This suggests a need for tertiary education IPE programs to move towards tailoring their education to

  16. Migration, settlement change and health in post-apartheid South Africa: triangulating health and demographic surveillance with national census data. (United States)

    Collinson, Mark A; Tollman, Stephen M; Kahn, Kathleen


    World population growth will be increasingly concentrated in the urban areas of the developing world; however, some scholars caution against the oversimplification of African urbanization noting that there may be "counter-urbanization" and a prevailing pattern of circular rural-urban migration. The aim of the paper is to examine the ongoing urban transition in South Africa in the post-apartheid period, and to consider the health and social policy implications of prevailing migration patterns. Two data sets were analysed, namely the South African national census of 2001 and the Agincourt health and demographic surveillance system. A settlement-type transition matrix was constructed on the national data to show how patterns of settlement have changed in a five-year period. Using the sub-district data, permanent and temporary migration was characterized, providing migration rates by age and sex, and showing the distribution of origins and destinations. The comparison of national and sub-district data highlight the following features: urban population growth, particularly in metropolitan areas, resulting from permanent and temporary migration; prevailing patterns of temporary, circular migration, and a changing gender balance in this form of migration; stepwise urbanization; and return migration from urban to rural areas. Policy concerns include: rural poverty exacerbated by labour migration; explosive conditions for the transmission of HIV; labour migrants returning to die in rural areas; and the challenges for health information created by chronically ill migrants returning to rural areas to convalesce. Lastly, suggestions are made on how to address the dearth of relevant population information for policy-making in the fields of migration, settlement change and health.

  17. Nordic exchange of students and climate change. (United States)

    Thomsson, A.


    Since the end of 2010 and until the summer of 2011 two upper secondary schools in Höyanger, Norway and Ronneby, Sweden had the possibility to take part in a project called Nordplus junior. The main aims of the program are: • To promote Nordic languages and culture and mutual Nordic-Baltic linguistic and cultural understanding. • To contribute to the development of quality and innovation in the educational systems for life-long learning in the participating countries by means of educational cooperation, development projects, exchanges and networking. • To support, develop, draw benefit from and spread innovative products and processes in education through systematic exchange of experiences and best practice. • To strengthen and develop Nordic educational cooperation and contribute to the establishment of a Nordic-Baltic educational area. The students did research on climate change and the impact on local and regional areas. Many questions had to be answered, giving an explanation to what happens if the climate changes. Questions related to Höyanger, Norway What happens to life in Norwegian fiords? Which attitudes do youngsters and adults have about climate change and what actions do they take? What does a rise in sea level mean for Höyanger? How are different tourist attractions affected in western Norway? Questions related to Ronneby, Sweden How is the regional fauna and flora affected? What will happen to agriculture and forestry? What do adults and youngsters know about consequences of a possible climate change? What happens to the people of Ronneby if the sea level rises? Are there any positive outcomes if the climate changes? Conclusions In Norwegian fiords there could be benefits because fish are growing faster in the winter because of an increased temperature. At the same time there could be an imbalance in the ecosystem because of a change in the living ranges of different species. Most of the young boys and girls in Höyanger, Norway were

    Socio-demographic factors play a significant role in increasing the individual's climate change awareness and in setting a favorable individual attitude towards its mitigation. To better understand how the adversative effects of climate change can be mitigated, this study attempts to investigate the impact of socio-demographic factors on the mitigating actions of the individuals (MAOI) on climate change. Qualitative data were collected from a face-to-face survey of 360 respondents in the Kuala Lumpur region of Malaysia through a close-ended questionnaire. Analysis was conducted on the mediating effects of attitudinal variables through the path model by using the SEM. Findings indicate that the socio-demographic factors such as gender, age, education, income, and ethnicity can greatly influence the individual's awareness, attitude, risk perception, and knowledge of climate change issues. The results drawn from this study also revealed that the attitudinal factors act as a mediating effect between the socio-demographic factors and the MAOI, thereby, indicating that both the socio-demographic factors and the attitudinal factors have significant effects on the MAOI towards climate change. The outcome of this study can help policy makers and other private organizations to decide on the appropriate actions to take in managing climate change effects. These actions which encompass improving basic climate change education and making the public more aware of the local dimensions of climate change are important for harnessing public engagement and support that can also stimulate climate change awareness and promote mitigating actions to n protect the environment from the impact of climate change.

  20. Predicting the educational performance of Isfahan University students of medical sciences based on their behaviour profile, mental health and demographic characteristic. (United States)

    Samouei, Rahele; Fooladvand, Maryam; Janghorban, Shahla; Khorvash, Fariba


    The issue of students' academic failure is one of the most important educational, economic, and social issues. Cognizance of the factors related to academic downfall is so efficient in its prevention and control and leads to protecting governmental assets and labor force. In order to achieve this goal, this study intends to determine the predictive factors of the students' academic performance in Isfahan University of Medical Sciences in terms of their personality profile, mental health, and their demographic characteristics. This study was a descriptive-correlation study on 771 students who entered Isfahan University of Medical Sciences between 2005 and 2007. The information was gathered through using the students' educational and clinical files (for measuring personality characteristics and mental health) and SAMA Software (To get the mean scores). Minnesota Multiphasic Personality Inventory short form and General Health Questionnaire were used for collecting clinical data. The data were analyzed using SPSS 15 (stepwise regression coefficient, variance analysis, Student's t-test, and Spearman correlation coefficient). The results showed that the aforementioned students obtained a normal average for their personality profile and mental health indicators. Of all the reviewed variables, education, age, gender, depression, and hypochondria were the predictive factors of the students' educational performance. It could be concluded that some of the personality features, mental health indicators, and personality profile play such a significant role in the students' educational life that the disorder in any of them affects the students' educational performance and academic failure.

  1. Classic And "Next Generation" Citizen Science: Expanding Data-gathering And Participant Demographics To Better Document Global Environmental Change. (United States)

    Haines-Stiles, G.


    Long-standing citizen science projects such as Audubon's Christmas Bird Count have generated useful data about species range and population numbers for more than 100 years. Recent IPCC reports and the U.S. National Climate Assessment (NCA) routinely include data about changing ecosystems and enviroments. Today new forms of citizen science are beginning to join such classic examples and broaden the demographics of participants and the kinds of information that can be captured, shared and analyzed. Surfers and scientists are hoping to record near-shore measurements of ocean acidification in Smartfin, through GPS, accelerometers and pH sensors on surfboards. Trout Unlimited is working on "Angler Science", documenting water temperature and stream quality in a changing climate, and using DNA analysis to track invasive species. The West Oakland Environmental Indicators Project is adding community mobilization in the face of sea level rise to its decade-long work on air pollution, particulates and asthma. The National Phenology Network encourages year-long observations using the "-Nature's Notebook" app that extend beyond anything possible using government-funded research alone. Understanding oceans, protecting rivers and identifying long-term patterns can contribute useful data to future NCAs, helping meet the otherwise challenging goal of "continuous assessment." How can we manage what we can't measure, for reasons of limited staff or resources? This presentation will offer one answer: by enlisting more and more citizen scientists--sportsmen and women, hobbyists and outdoor enthusiasts who may not even self identify as "citizen scientists"--pursuing their passions while also contributing valuable GEC data. The presentation will also touch on what kinds of information infrastructure can help assure data quality when traditional citizen science is expanded in these ways.

  2. The role of behavioral economic incentive design and demographic characteristics in financial incentive-based approaches to changing health behaviors: a meta-analysis. (United States)

    To evaluate the use of behavioral economics to design financial incentives to promote health behavior change and to explore associations with demographic characteristics. Studies performed by the Center for Health Incentives and Behavioral Economics at the University of Pennsylvania published between January 2006 and March 2014. Randomized, controlled trials with available participant-level data. Studies that did not use financial incentives to promote health behavior change were excluded. Participant-level data from seven studies were pooled. Meta-analysis on the pooled sample using a random-effects model with interaction terms to examine treatment effects and whether they varied by incentive structure or demographic characteristics. The pooled study sample comprised 1403 participants, of whom 35% were female, 70% were white, 24% were black, and the mean age was 48 years (standard deviation 11.2 years). In the fully adjusted model, participants offered financial incentives had higher odds of behavior change (odds ratio [OR]: 3.96; p financial incentives and gender, age, race, income, or education. When further adjusting for incentive structure, blacks had higher odds than whites of achieving behavior change (OR: 1.67; p Financial incentives designed using concepts from behavioral economics were effective for promoting health behavior change. There were no large and consistent relationships between the effectiveness of financial incentives and observable demographic characteristics. Second-order examinations of incentive structure suggest potential relationships among the effectiveness of financial incentives, incentive structure, and the demographic characteristics of race and income.

    Full Text Available Abstract Background National and international child health surveys have indicated an increase in childhood obesity in China. The increase has been attributed to a rising standard of living, increasing availability of unhealthy foods, and a lack of knowledge about healthy diet. The objective of this study was to assess the effect of selected socio-demographic characteristics on the BMI, nutrition knowledge, and eating behavior of elementary school children. Methods Multistage stratified cluster sampling was used. Information on demographics, nutrition knowledge, and eating behavior was gathered by means of questionnaires. The schools’ doctors provided the height and weight data. The study was set in one economically advantaged and one economically disadvantaged province in China. The participants were Grade 3 students, ages 8–10 years (N = 3922. Results A cluster analysis identified four socio-demographic variables distinguished by parental education and family living arrangement. A one-way ANOVA compared differences among the clusters in BMI, child nutrition knowledge, and child eating behavior. Students in the cluster with lowest parent education level had the lowest nutrition knowledge scores and eating behavior scores. There was no significant benefit from college education versus high school education of parents in the other three clusters. BMI was not affected by parent education level. Conclusion The nutrition status of elementary school age children will benefit most by increasing the general level of education for those adults who are presently least educated.

  9. Storytelling and Technology Combine to Create Student Engagement Around Locally Relevant Climate Change Topics. (United States)

    Leckey, E.; Littrell-Baez, M.; Tayne, K.; Gold, A. U.; Okochi, C.; Oonk, D.; Smith, L. K.; Lynds, S. E.


    Storytelling is a powerful way for students to engage with science topics, particularly topics that may initially seem too broad to impact their lives, like climate change. Empowering students to telling a personal story about climate change's effects and helping them turn their story into a film is powerful approach. Especially because these films can be shared globally and gives students a voice around a complex topic like climate change. Here, we present impacts of the Lens on Climate Change program (LOCC), which engages middle and high school students in producing short films featuring how climate change impacts their communities. LOCC is offered as an intensive week-long summer program and as an extracurricular program during the school year. The majority of student participants are recruited from historically underserved communities and come from ethnical and socioeconomically diverse backgrounds. Survey data revealed that LOCC participants had a significant increase in their belief in the reality of climate change after participation in their program relative to students in a demographically-matched control groups. Furthermore, participant responses on reflection surveys given after the program included statements that suggest that students had begun thinking more deeply about climate change as a serious global challenge and felt empowered to take actions to mitigate climate change and/or spread awareness in their communities. The majority of students in the LOCC program also reported being very proud of their film and intended to share their film with their friends and family. Additionally, we explored the long-term impacts of participation by interviewing students a year after the program and offered them the opportunity to make a subsequent film. Students in this "advanced group" reported being more aware of climate change in their community following making their films and were enthusiastic to increase their filmmaking skills through producing additional

    Full Text Available In order to determine the prevalence of depression among high school students of Tehran, the Beck depression test questionnaire was distributed among 1478 students of Tehran 19 districts, using a methodical approach. Data gathered after completion of the forms showed the following results: 11.4% of the students were on the border line of affliction, 12.6% had a medium degree of disorder, 4.2% suffered from a severe level and 0.4% showed a much higher degree of depression. The older these students were, the more prevalent was the depression among them. The girls showed a higher degree of disorder than the boys at a 1.4 to 1 ratio. The lowest degree was found among students of mathematics, whereas the students of literature showed the highest level. The rate was much lower among students of Shahed schools than that observed among students of evening classes. The research showed no relationship between the students depression and their parents profession. However, the higher level of parents' education was associated with lower levels of depression among their children. Finally, lower levels of disorder was observed among residents of private housings in comparison to what was found among students residing in leased or mortgaged dwellings

    Full Text Available Introduction: Test -anxiety is one of the most common mental health problems among the students that can impair performance and leads to failure of the exam. So, this study aimed to determine the rate of exam-anxiety among Kermanshah University of Medical Sciences' students. Methods: This cross sectional-analytic study was conducted on 510 students of Kermanshah University of Medical Sciences by convenience sampling method in 2014. In this study, data collection tool was Test-Anxiety questionnaire includes 25 questions. Data were analyzed with the Pearson correlation and t-test using SPSS 16 software. Results: 198 students (38. 8% had mild exam-anxiety, 140 students (27. 5% moderate exam-anxiety and 172 students (33. 7% had severe exam-anxiety. The difference between the mean of anxiety scores was significant at various fields of study (P <0. 05.  Midwifery students experienced more stress in comparison with the students of other fields. There was a significant relationship between exam anxiety level, and the variables of gender, location, age and total grades average of students (P<0/05. There was not a significant relationship between exam anxiety level and marital status, parental occupation, semester entrance and employment of students. Conclusion: Due to the high level of exam anxiety among the different fields of medicine as well as the negative effect of this type of anxiety on academic performance of students, the necessity of the use of psychological services, counseling, identification of causes of anxiety, and planning for decreasing this problem was recommended. Obviously, in this regard, more attention should be paid to the highest-risk groups such as female midwifery students.

  16. Changes and specificities in health behaviors among healthcare students over an 8-year period (United States)

    Delay, J.; Grigioni, S.; Déchelotte, P.; Ladner, J.


    Background Healthcare students are future health care providers and serve as role models and coaches to enhance behaviors for healthy lifestyles. However healthcare students face multiple stressors that could lead to adopting risk behaviors. Objectives To assess the changes in health risk factors among healthcare students between 2007 and 2015, and to identify specific health behaviors based on the curriculum in a population of healthcare students: Methods Two cross sectionnal studies were conducted in 2007 and 2015 among nursing, medical, pharmacy, and physiotherapy students (Rouen, France). During compulsory courses and examination sessions students filled self-administered questionnaires on socio-demographic characteristics and behavior as: tobacco smoking, alcohol consumption, cannabis consumption, eating disorders, regular practice of sport, perceived health, stress and use of psychotropic drugs. Results 2,605 healthcare students were included (1,326 in 2007 and 1,279 in 2015), comprising 1,225 medical students (47.0%), 738 nursing students (28.3%), 362 pharmacy students (13.9%), and 280 physiotherapy students (10.8%). Between 2007 and 2015, occasional binge drinking and regular practice of sport increased significantly among healthcare students, respectively AOR = 1.48 CI95% (1.20–1.83) and AOR = 1.33 CI95% (1.11–1.60), regular cannabis consumption decreased significantly, AOR = 0.32 CI95% (0.19–0.54). There was no change in smoking or overweight/obese. There was a higher risk of frequent binge drinking and a lower risk of tobacco smoking in all curricula than in nursing students. Medical students practiced sport on a more regular basis, were less overweight/obese, had fewer eating disorders than nursing students. Conclusion Our findings demonstrate a stable frequency of classic behaviors as smoking but a worsening of emerging behaviors as binge drinking among healthcare students between 2007 and 2015. Health behaviors differed according to healthcare

  17. Different routes of demographic changes in former Eastern bloc states at the turn of the 21st century based on the examples of Poland and Ukraine (United States)

    Flaga, Małgorzata


    The article concerns the most important demographic processes that took place in two post-communist countries, Poland and Ukraine, after 1990. These countries differ in terms of economic changes that they have gone through so far. In case of Poland we may consider it as a success in reforming the economy, despite the fact that it caused certain negative social phenomena, e.g. large unemployment. On the other hand, in Ukraine, economic crisis was not stopped, but it is also deepening and its results have become significant modifiers of population processes. The changes in population number, natural growth and migration in both countries are the subjects of detailed analyses. They were presented in the context of the "secondary demographic transition", which Poland and Ukraine entered rapidly at the beginning of 1990, along with economic transformation and social changes.

  18. A spatial analysis of population dynamics and climate change in Africa: potential vulnerability hot spots emerge where precipitation declines and demographic pressures coincide (United States)

    López-Carr, David; Pricope, Narcisa G.; Aukema, Juliann E.; Jankowska, Marta M.; Funk, Christopher C.; Husak, Gregory J.; Michaelsen, Joel C.


    We present an integrative measure of exposure and sensitivity components of vulnerability to climatic and demographic change for the African continent in order to identify “hot spots” of high potential population vulnerability. Getis-Ord Gi* spatial clustering analyses reveal statistically significant locations of spatio-temporal precipitation decline coinciding with high population density and increase. Statistically significant areas are evident, particularly across central, southern, and eastern Africa. The highly populated Lake Victoria basin emerges as a particularly salient hot spot. People located in the regions highlighted in this analysis suffer exceptionally high exposure to negative climate change impacts (as populations increase on lands with decreasing rainfall). Results may help inform further hot spot mapping and related research on demographic vulnerabilities to climate change. Results may also inform more suitable geographical targeting of policy interventions across the continent.

  20. Reasons for and challenges of recent increases in teen birth rates: a study of family planning service policies and demographic changes at the state level. (United States)

    Yang, Zhou; Gaydos, Laura M


    After declining for over a decade, the birth rate in the United States for adolescents aged 15-19 years increased by 3% in 2006 and 1% again in 2007. We examined demographic and policy reasons for this trend at state level. With data merged from multiple sources, descriptive analysis was used to detect state-level trends in birth rate and policy changes from 2000 to 2006, and variations in the distribution of teen birth rates, sex education, and family planning service policies, and demographic features across each state in 2006. Regression analysis was then conducted to estimate the effect of several reproductive health policies and demographic features on teen birth rates at the state level. Instrument variable was used to correct possible bias in the regression analysis. Medicaid family planning waivers were found to reduce teen birth rates across all ages and races. Abstinence-only education programs were found to cause an increase in teen birth rates among white and black teens. The increasing Hispanic population is another driving force for high teen birth rates. Both demographic factors and policy changes contributed to the increase in teen birth rates between 2000 and 2006. Future policy and behavioral interventions should focus on promoting and increasing access to contraceptive use. Family planning policies should be crafted to address the special needs of teens from different cultural backgrounds, especially Hispanics. Copyright 2010 Society for Adolescent Health and Medicine.

    Howe, E. Lance; Martin, Stephanie


    This paper addresses broad demographic and economic characteristics of the Arctic-Yukon-Kuskokwim region (AYK) of Alaska. AYK human population growth has generally been moderate over time. Because out-migration regularly exceeds in-migration, especially in the villages, population growth is mainly a product of natality. We anticipate future population growth patterns will be similar. In terms of regional characteristics, the linguistically and geographically distinct populations of the AYK re...

  3. Students' Changing Attitudes and Aspirations Towards Physics During Secondary School (United States)

    Sheldrake, Richard; Mujtaba, Tamjid; Reiss, Michael J.


    Many countries desire more students to study science subjects, although relatively few students decide to study non-compulsory physics at upper-secondary school and at university. To gain insight into students' intentions to study non-compulsory physics, a longitudinal sample (covering 2258 students across 88 secondary schools in England) was surveyed in year 8 (age 12/13) and again in year 10 (age 14/15). Predictive modelling highlighted that perceived advice, perceived utility of physics, interest in physics, self-concept beliefs (students' subjective beliefs of their current abilities and performance) and home support specifically orientated to physics were key predictors of students' intentions. Latent-transition analysis via Markov models revealed clusters of students, given these factors at years 8 and 10. Students' intentions varied across the clusters, and at year 10 even varied when accounting for the students' underlying attitudes and beliefs, highlighting that considering clusters offered additional explanatory power and insight. Regardless of whether three-cluster, four-cluster, or five-cluster models were considered, the majority of students remained in the same cluster over time; for those who transitioned clusters, more students changed clusters reflecting an increase in attitudes than changed clusters reflecting a decrease. Students in the cluster with the most positive attitudes were most likely to remain within that cluster, while students in clusters with less positive attitudes were more likely to change clusters. Overall, the cluster profiles highlighted that students' attitudes and beliefs may be more closely related than previously assumed, but that changes in their attitudes and beliefs were indeed possible.

  4. It's A Gassy World: Middle School Students Investigate Climate Change (United States)

    Romano, C.


    When middle school students are asked about our changing earth system, their responses likely include terms like global warming, climate change, and greenhouse gases. However, many students struggle to understand how it all fits together, and sometimes they hear conflicting information or myths about climate change. This activity allows students to explore the impacts of warming oceans and oceans' absorption of carbon dioxide (CO2) through a student planned and carried out investigation that begins with a pre-laboratory engagement and exploration piece, includes a laboratory component, and concludes with an explanation where students analyze their data and interpret their results through the claim-evidence-reasoning framework. It's a Gassy World was developed with three-dimensional instruction in mind to introduce middle school students to the relationship between warming oceans and changes in carbon dioxide (CO2) absorption in the oceans. Students explore disciplinary core ideas in the Earth and Space Sciences discipline of the Next Generation Science Standards (NGSS) using crosscutting concepts and science and engineering practices. Specifically, students study CO2 as a greenhouse gas and the effect of increased atmospheric CO2 levels on global climate change by planning and carrying out their own investigations. We structured this activity in a 5E format that can take place in four to five days during a climate change unit. After piloting this activity in over 20 formal classrooms and with 5 informal education groups, we have seen how It's a Gassy World helps support inquiry in the classroom and allows students to experience crosscutting concepts and science and engineering practices in NGSS. We found that students were engaged and actively learning throughout the activity. Student work and pilot teacher feedback indicated that, through this activity, many students increased their understanding of CO2 as a greenhouse gas and recognized that warmer oceans will

  6. Integrating data from multiple sources for insights into demographic processes: Simulation studies and proof of concept for hierarchical change-in-ratio models. (United States)

    Nilsen, Erlend B; Strand, Olav


    We developed a model for estimating demographic rates and population abundance based on multiple data sets revealing information about population age- and sex structure. Such models have previously been described in the literature as change-in-ratio models, but we extend the applicability of the models by i) using time series data allowing the full temporal dynamics to be modelled, by ii) casting the model in an explicit hierarchical modelling framework, and by iii) estimating parameters based on Bayesian inference. Based on sensitivity analyses we conclude that the approach developed here is able to obtain estimates of demographic rate with high precision whenever unbiased data of population structure are available. Our simulations revealed that this was true also when data on population abundance are not available or not included in the modelling framework. Nevertheless, when data on population structure are biased due to different observability of different age- and sex categories this will affect estimates of all demographic rates. Estimates of population size is particularly sensitive to such biases, whereas demographic rates can be relatively precisely estimated even with biased observation data as long as the bias is not severe. We then use the models to estimate demographic rates and population abundance for two Norwegian reindeer (Rangifer tarandus) populations where age-sex data were available for all harvested animals, and where population structure surveys were carried out in early summer (after calving) and late fall (after hunting season), and population size is counted in winter. We found that demographic rates were similar regardless whether we include population count data in the modelling, but that the estimated population size is affected by this decision. This suggest that monitoring programs that focus on population age- and sex structure will benefit from collecting additional data that allow estimation of observability for different age- and

  7. The Attitude of Students Who Are Native Speakers of Turkish in England towards Turkish Lessons Based on Their Demographic Characteristics

    Directory of Open Access Journals (Sweden)

    Nazik Müge TEKİN


    Full Text Available Mother tongue education (or instruction plays quite a significant role in individual students’ success in both social and academic areas. A qualified mother tongue education is crucial in ensuring those students become successful adults in their later life and adopt their own culture and identities. From time to time, there might be students who have mother tongue medium education along with those who have other languages as the medium of instruction. Among those bilingual students there are children of Turkish citizens who immigrated to Western Europe as workers. Mother tongue education is a necessity for bilingual individuals to protect their identities, to adopt to the society they already live in and to learn the language used in that very society much more easily. This makes it more important for the bilingual Turkish children living in foreign countries to receive mother tongue education. In this vein, the attitudes of Turkish students, who live in England, towards the Turkish language class are examined. 105 Turkish students between 11 and 18 years enrolled in Wisdom and Namık Kemal Turkish School in the UK were requested to fill in a questionnaire. Based on their responses, their opinions about the Turkish language class were evaluated.

  12. Demographic expansion of two Tamarix species along the Yellow River caused by geological events and climate change in the Pleistocene. (United States)

    Liang, Hong-Yan; Feng, Zhi-Pei; Pei, Bing; Li, Yong; Yang, Xi-Tian


    The geological events and climatic fluctuations during the Pleistocene played important roles in shaping patterns of species distribution. However, few studies have evaluated the patterns of species distribution that were influenced by the Yellow River. The present work analyzed the demography of two endemic tree species that are widely distributed along the Yellow River, Tamarix austromongolica and Tamarix chinensis, to understand the role of the Yellow River and Pleistocene climate in shaping their distribution patterns. The most common chlorotype, chlorotype 1, was found in all populations, and its divergence time could be dated back to 0.19 million years ago (Ma). This dating coincides well with the formation of the modern Yellow River and the timing of Marine Isotope Stages 5e-6 (MIS 5e-6). Bayesian reconstructions along with models of paleodistribution revealed that these two species experienced a demographic expansion in population size during the Quaternary period. Approximate Bayesian computation analyses supported a scenario of expansion approximately from the upper to lower reaches of the Yellow River. Our results provide support for the roles of the Yellow River and the Pleistocene climate in driving demographic expansion of the populations of T. austromongolica and T. chinensis. These findings are useful for understanding the effects of geological events and past climatic fluctuations on species distribution patterns.

  17. Acculturation and changes in dietary behavior and anthropometric measures among Chinese international students in South Korea. (United States)

    Lee, Jounghee; Gao, Ran-Ran; Kim, Jung-Hee


    International students face dissimilar food environments, which could lead to changes in dietary behaviors and anthropometric characteristics between before and after migration. We sought to examine the risk factors, including dietary behaviors, acculturation, and demographic characteristics, related to overweight subjects residing in South Korea. We conducted a cross-sectional study, collecting data from 142 Chinese international students (63 males, 79 females) in 2013. The mean age of the subjects was 25.4 years, and almost half of them immigrated to South Korea to earn a master's degree or doctoral degree (n = 70, 49.3%). Chinese international students showed an increase in skipping meals and eating speed, but a decrease in the frequency of fruit and vegetable consumption in South Korea compared to when they lived in China. We found a statistically significant increase in weight (69.4 → 73.9 kg) and BMI (22.4 → 23.8 kg/m(2)) for male subjects (P < 0.001) but no change for female subjects. We also found that overweight subjects were more likely to be highly acculturated and male compared with normal-weight subjects. Among Chinese international students living in South Korea, male and more highly acculturated subjects are more vulnerable to weight gain. This study provides useful information to design tailored nutrition intervention programs for Chinese international students.

  7. A brief history of the changing occupations and demographics of coleopterists from the 18th through the 20th century. (United States)

    Elias, Scott A


    Systematic entomology flourished as a branch of Natural History from the 1750s to the end of the nineteenth century. During this interval, the "era of Heroic Entomology," the majority of workers in the field were dedicated amateurs. This article traces the demographic and occupational shifts in entomology through this 150-year interval and into the early twentieth century. The survey is based on entomologists who studied beetles (Coleoptera), and who named sufficient numbers of species to have their own names abbreviated by subsequent taxonomists. In the eighteenth century, 27 entomologists achieved this level of prominence, of whom 37% were academics, 19% were doctors, 11% had private incomes, 19% were clergymen, and 8% were government officials. Many of those with private incomes were members of the European aristocracy, and all but one were European men. The nineteenth century list included 192 entomologists, of whom 17% were academics, 16% were museum curators, 2% were school teachers, 15% were doctors, 6% were military men, 7% were merchants, 2% were government entomologists, 6% had private incomes, 5% were clergymen, 5% were government officials, and 4% were lawyers. The demographics of entomology shifted dramatically in the nineteenth century. Whereas many of the noteworthy entomologists of the eighteenth century were German, Swedish, or French, in the nineteenth century, many more European countries are represented, and almost one-fifth of the noteworthy entomologists were from the United States. The nineteenth century list, like the eighteenth century list, contains no women. By the twentieth century, 63% of 178 noteworthy systematic entomologists were paid professionals, teaching entomology courses in universities, or studying insect taxonomy in museums and government-sponsored laboratories. Only one person on the twentieth century list had a private income, but women (ten individuals) were included on the list for the first time.

  8. Demographic change in the Arab world: the impact of migration, education and taxes in Egypt and Morocco. (United States)

    Courbage, Y


    The populations of Egypt and Morocco have grown since the beginning of the century from approximately 10 to 57 million and less than 5 to 25.5 million, respectively. Egypt and Morocco are two of the most populous Arab countries. After a long period of demographic growth, they adopted less pronatalist legislation and implemented family planning programs starting in the 1960s. Egypt's rate of total fertility (TFR) at that time was 6.7 children per woman, lower than most of the Arab world and lower than Morocco's 7.2. Egypt's fertility since then, however, has remained at 5-6, only dropping below 5 in 1989. TFR in Morocco increased to 7.4 in 1973, declined to 5.9 over the period 1973-77, and fell below 4 in 1989. The author questions why the goals of fertility control programs have not been reached in Egypt, yet have been surpassed in Morocco. Available data on contraceptive prevalence and breastfeeding practices would predict the opposite to be the case. 35.9% used birth control methods in Morocco in 1987 and 37.8% in Egypt in 1988. 6.9%, however, used less effective traditional methods in Morocco compared to only 2.4% who used such methods in Egypt. Egyptian women breastfeed their babies for 17.3 months compared to 14.4 months among Moroccan women, while between the ages 20-24, 60% of Egyptian women are married compared to 45% of women in Morocco. Moroccan and Egyptian families resist traditional explanations of demographic transition. It is concluded that although educational status affects fertility in the Maghrib and Mashriq, greater female labor force participation, state-citizen fiscal relations, and foreign migration play major determining roles.

  10. The relationship between sun protection policies and practices in schools with primary-age students: the role of school demographics, policy comprehensiveness and SunSmart membership. (United States)

    Dono, J; Ettridge, K A; Sharplin, G R; Wilson, C J


    Schools can implement evidence-based sun protection policies that guide practices to help protect children from harmful sun exposure. This national study assessed the relationship between the existence and comprehensiveness of written policies and the comprehensiveness of sun protection practices. The impact of school demographics on the strength of the relationship was also examined, as was the possibility that 'SunSmart' membership would have an additional impact on practices, beyond having any formal policy. In 2011-12, staff members of 1573 schools catering to primary-age students completed a self-administered survey about sun protection policies and practices (response rate of 57%). Results showed that schools with a written policy had more comprehensive practices than schools without a written policy. The relationship between having a written policy and sun protection practices was stronger for remote schools compared with metropolitan and regional schools, and for schools catering to both primary and secondary students compared with primary students only. In addition, policy comprehensiveness was associated with practice comprehensiveness, and SunSmart membership was indirectly related to practice comprehensiveness via policy comprehensiveness. These results indicate that written policies relate to practice comprehensiveness, but the strength of the association can vary according to the characteristics of the organization.

  11. Demographic and Social Correlates of Tobacco, Alcohol and Cannabis Use Among 15-16-Year-Old Students in Albania: Results of the ESPAD Survey

    Directory of Open Access Journals (Sweden)

    Toçi Ervin


    Full Text Available AIMS – Our aim was to assess the demographic and social factors associated with lifetime use of tobacco, alcohol and cannabis among school students aged 15–16 in Albania in order to make information and knowledge available for health promotion specialists working on substance use prevention. DESIGN – This cross-sectional study was conducted in March–May 2011 in the framework of the European School Survey Project on Alcohol and Other Drugs (ESPAD. In total, 3189 students born in 1995 participated in the survey. The standardised ESPAD questionnaire was used to collect data about substance use. RESULTS – Our multivariable adjustment analysis showed that being a male and having easy access to cigarettes were the only universal factors significantly increasing the likelihood of ever using tobacco, alcohol or cannabis. Own smoking was strongly and significantly associated with alcohol and cannabis use. The associations of own substance use with peer substance consumption were weak to moderate. CONCLUSIONS – Own smoking seems to be the most important single independent risk factor which strongly and significantly predicted alcohol and cannabis use among Albanian school students. Policy makers need to strengthen the rule of law whereas health promotion professionals should firmly address smoking in adolescence through target interventions.

  12. Medical Students' Perspectives on Implementing Curriculum Change at One Institution. (United States)

    Yengo-Kahn, Aaron M; Baker, Courtney E; Lomis, And Kimberly D


    Training physicians to be effective practitioners throughout their careers begins in undergraduate medical education with particular focus on self-directed inquiry, professional and interprofessional development, and competency-based assessment. A select number of medical schools are restructuring their curricula by placing the student at the center of content delivery to enhance the learning experience. While this restructuring may benefit the adult learner, administrators often make assumptions about how students will perceive and respond to such innovative and unfamiliar educational concepts. This can create a disconnect between students and their curriculum. Administrative mindfulness of student experiences is needed to ensure successful implementation of curricular change, facilitate the transition from old to new modalities, and train competent physician graduates.Vanderbilt University School of Medicine (VUSM) recently completed a curriculum update, and student representatives have been essential participants in the transition, from the earliest stages in preplanning to rapid-cycle feedback as the curriculum runs. Two of the authors are members of VUSM's Student Curriculum Committee, which facilitates gathering and relaying student feedback to the administration. Drawing from their experiences, five specific considerations to address and manage when implementing student-centered curricular change are presented: (1) Communicate the rationale, (2) acknowledge anxiety, (3) adjust extracurricular leadership roles, (4) manage "The Bulge" of learners in the clinical environment, and (5) foster ongoing collaboration of students and administrators. For each consideration, examples and proposed solutions are provided.

  13. Prey change behaviour with predation threat, but demographic effects vary with prey density: experiments with grasshoppers and birds. (United States)

    Belovsky, Gary E; Laws, Angela Nardoni; Slade, Jennifer B


    Increasingly, ecologists emphasize that prey frequently change behaviour in the presence of predators and these behavioural changes can reduce prey survival and reproduction as much or more than predation itself. However, the effects of behavioural changes on survival and reproduction may vary with prey density due to intraspecific competition. In field experiments, we varied grasshopper density and threat of avian predation and measured grasshopper behaviour, survival and reproduction. Grasshopper behaviour changed with the threat of predation and these behavioural changes were invariant with grasshopper density. Behavioural changes with the threat of predation decreased per capita reproduction over all grasshopper densities; whereas the behavioural changes increased survival at low grasshopper densities and then decreased survival at high densities. At low grasshopper densities, the total reproductive output of the grasshopper population remained unchanged with predation threat, but declined at higher densities. The effects of behavioural changes with predation threat varied with grasshopper density because of a trade-off between survival and reproduction as intraspecific competition increased with density. Therefore, resource availability may need to be considered when assessing how prey behavioural changes with predation threat affect population and food web dynamics. © 2011 Blackwell Publishing Ltd/CNRS.

  16. Climate Change Education: Student Media Production to Educate and Engage (United States)

    Rooney-Varga, J. N.; Brisk, A. A.; Ledley, T. S.; Shuldman, M.


    Climate change education offers many challenges, including the complexity of the natural and human systems involved, a need for a multi-disciplinary perspective, and the psychological barriers to learning that result from a problem that frequently elicits a sense of being overwhelmed and powerless. The implications of climate change impacts and/or solutions can be especially overwhelming for today's students, who are likely to be confronted with many projected changes within their lifetimes. We are developing approaches to incorporate video production by students at both the high school and university levels in order to overcome many of the challenges unique to climate change education. Through media production, students are asked to convey complex topics using clear, simple language and metaphor, so their content knowledge must be deep enough to educate others. Video production is a team effort (director, camera person, editor, etc.) and inherently creates an opportunity for learning in a social context, which has been shown to lead to better learning outcomes in climate change education. Video production also promotes the basic tenets of engagement theory, in which a small group of students is in constant contact with the content and, ideally, creates a product that can be disseminated broadly. Lastly, putting students behind the camera can give them a voice and a sense of empowerment, fostering active participation in the learning process. While video is a medium that is readily disseminated to a broad audience, our focus is on the process (i.e., learning outcomes of students directly involved in media production), not the product. However, we have found that providing students with a means to add their voices to the broader public's discussion of climate change has a positive impact on student engagement with climate change science and on public awareness this problem beyond the classroom. While student-produced media pieces are not intended to provide in

  17. Predictors of Response and Mechanisms of Change in an Organizational Skills Intervention for Students with ADHD. (United States)

    Langberg, Joshua M; Becker, Stephen P; Epstein, Jeffery N; Vaughn, Aaron J; Girio-Herrera, Erin


    The purpose of the study was to evaluate predictors of response and mechanisms of change for the Homework, Organization, and Planning Skills (HOPS) intervention for middle school students with Attention-Deficit/Hyperactivity Disorder (ADHD). Twenty-three middle school students with ADHD (grades 6-8) received the HOPS intervention implemented by school mental health providers and made significant improvements in parent-rated materials organization and planning skills, impairment due to organizational skills problems, and homework problems. Predictors of response examined included demographic and child characteristics, such as gender, ethnicity, intelligence, ADHD and ODD symptom severity, and ADHD medication use. Mechanisms of change examined included the therapeutic alliance and adoption of the organization and planning skills taught during the HOPS intervention. Participant implementation of the HOPS binder materials organization system and the therapeutic alliance as rated by the student significantly predicted post-intervention outcomes after controlling for pre-intervention severity. Adoption of the binder materials organization system predicted parent-rated improvements in organization, planning, and homework problems above and beyond the impact of the therapeutic alliance. These findings demonstrate the importance of teaching students with ADHD to use a structured binder organization system for organizing and filing homework and classwork materials and for transferring work to and from school.

  18. Measuring change in critical thinking skills of dental students educated in a PBL curriculum. (United States)

    Pardamean, Bens


    This study measured the change in critical thinking skills of dental students educated in a problem-based learning (PBL) pedagogical method. The quantitative analysis was focused on measuring students' critical thinking skills achievement from their first through third years of dental education at the University of Southern California. This non-experimental evaluation was based on a volunteer sample of ninety-eight dental students who completed a demographics/academic questionnaire and a psychometric assessment known as the Health Sciences Reasoning Test (HSRT). The HSRT produced the overall critical thinking skills score. Additionally, the HSRT generated five subscale scores: analysis, inference, evaluation, deductive reasoning, and inductive reasoning. The results of this study concluded that the students showed no continuous and significant incremental improvement in their overall critical thinking skills score achievement during their PBL-based dental education. Except for the inductive reasoning score, this result was very consistent with the four subscale scores. Moreover, after performing the statistical adjustment on total score and subscale scores, no significant statistical differences were found among the three student groups. However, the results of this study found some aspects of critical thinking achievements that differed by categories of gender, race, English as first language, and education level.

  19. Clinical and socio-demographic characteristics of college students exposed to traumatic experiences: a census of seven college institutions in Northeastern Brazil.

    Directory of Open Access Journals (Sweden)

    Liana R Netto

    Full Text Available BACKGROUND: Epidemiological studies show that most of the adult population will be exposed to at least one potentially traumatic event in the course of his/her life; adolescence and early adulthood are the most vulnerable periods of life for exposure to traumatic experiences (70% of their deaths are due to external causes. Posttraumatic Stress Disorder is characterized by the development of dysfunctional symptoms that cause distress or social, academic, or occupational impairment, as result of exposure to a traumatic event. The aim of this multicentric study is to establish the proportion of college students, within seven institutions in Northeastern Brazil, who were exposed to traumatic experience and met PTSD criteria. METHODS/DESIGN: A one-phase census protocol of seven college institutions in three metropolitan regions in Northeastern Brazil was performed (April to July 2011. All students aged 18 years or older, matriculated and attending their first or final semester were eligible. The self-applied protocol consisted of a socio-demographic questionnaire and the following scales adjusted to Brazilian Portuguese standards Trauma History Questionnaire (THQ, PTSD Checklist-Civilian (PCL-C, Impulsivity Scale (BIS-11. Data were entered into SPSS 17.0. RESULTS: 2213 (85.5% students consented to participate, and completely filled in the protocols. Of these, 66.1% were woman, mean age 23.9 (SD 6.3, 82.7% were single, and 57.3% attended university outside their native cities. The total PTSD prevalence was 14%, and the median for frequency of trauma exposure was 5 events. CONCLUSION: A high frequency of exposure to violence, as well as a high rate of PTSD, suicide attempts, and high-risk sexual behavior was found in Brazilian college students. This highlights the importance of effective public health actions in relation to the prevention and treatment of PTSD and other dysfunctional behaviors resulting from traumatic exposure in young individuals

  20. Changes in food habits after migration among South Asians settled in Oslo: the effect of demographic, socio-economic and integration factors. (United States)

    Wandel, Margareta; Råberg, Marte; Kumar, Bernadette; Holmboe-Ottesen, Gerd


    The aim is to explore changes in food habits after migration, and the resultant present food consumption patterns, as well as the effect of demographic, socio-economic and integration factors on these changes. Analyses were based on data collected through the Oslo Immigrant Health study, from 629 persons 30-60 years of age, born in Sri Lanka and Pakistan, and living in Oslo, Norway. A majority of the Sri Lankans reported increase in the consumption of meat, milk, butter, margarine and potatoes. Around half of those from Pakistan reported increased consumption of oil, meat, fish and potatoes. Both groups reported a decrease in bean and lentil consumption. Multivariate regression showed that age was negatively related to increases in butter and margarine consumption, and a good command of the Norwegian language reduced the likelihood of increased consumption of oil and butter. The likelihood of having present fat and sugar rich food patterns were reduced with age and years of education, whereas scoring high on an index of integration increased the likelihood of a fat rich food pattern. In conclusion, a number of demographic and socio-cultural factors may modify the changes in food habits after migration. Some of these may have substantial health implications.

  1. Will Climate Change, Genetic and Demographic Variation or Rat Predation Pose the Greatest Risk for Persistence of an Altitudinally Distributed Island Endemic?

    Directory of Open Access Journals (Sweden)

    Alison Shapcott


    Full Text Available Species endemic to mountains on oceanic islands are subject to a number of existing threats (in particular, invasive species along with the impacts of a rapidly changing climate. The Lord Howe Island endemic palm Hedyscepe canterburyana is restricted to two mountains above 300 m altitude. Predation by the introduced Black Rat (Rattus rattus is known to significantly reduce seedling recruitment. We examined the variation in Hedyscepe in terms of genetic variation, morphology, reproductive output and demographic structure, across an altitudinal gradient. We used demographic data to model population persistence under climate change predictions of upward range contraction incorporating long-term climatic records for Lord Howe Island. We also accounted for alternative levels of rat predation into the model to reflect management options for control. We found that Lord Howe Island is getting warmer and drier and quantified the degree of temperature change with altitude (0.9 °C per 100 m. For H. canterburyana, differences in development rates, population structure, reproductive output and population growth rate were identified between altitudes. In contrast, genetic variation was high and did not vary with altitude. There is no evidence of an upward range contraction as was predicted and recruitment was greatest at lower altitudes. Our models predicted slow population decline in the species and that the highest altitude populations are under greatest threat of extinction. Removal of rat predation would significantly enhance future persistence of this species.

  5. The changing demographics of total joint arthroplasty recipients in the United States and Ontario from 2001 to 2007. (United States)

    Ravi, Bheeshma; Croxford, Ruth; Reichmann, William M; Losina, Elena; Katz, Jeffrey N; Hawker, Gillian A


    The rates of total joint arthroplasty (TJA) of the hip and knee have increased in North America over the last decade. While initially designed for elderly patients (>70 years of age), several reports suggest that an increasing number of younger patients are undergoing joint replacements. This suggests that more people are meeting the indication for TJA earlier in their lives. Alternatively, it might indicate a broadening of the indications for TJA. We used the administrative databases available at the Healthcare Cost and Utilization Project (HCUP) and the Institute for Clinical Evaluative Sciences (ICES) to determine the rates of TJA of the hip and knee in the United States, and Ontario, Canada, respectively. We determined the crude rates of THA and TKA in both areas for four calendar years (2001, 2003, 2005 and 2007). We also calculated the age- and sex-standardised rates of THA and TKA in both areas for each time period. We compared the age distribution of TJA recipients between the US and Ontario, and within each area over time. The crude and standardised rates of THA and TKA increased over time in both the US and Ontario. The crude rates of THA were higher in the US in 2001 and 2003, but were not significantly different from the rate in Ontario in 2005 and 2007. The crude rates of TKA were consistently higher in the US for all time periods. In addition, the US consistently had more THA and TKA recipients in 'younger' age categories (age). While the age- and sex-standardised rates of TKA were greater in the US in all time periods, the relative increase in rates from 2001 to 2007 was greater in Ontario (US - 59%, Ontario - 73%). For both the US and Ontario, there was a significant shift in the demographic of THA and TKA recipients to younger patients (p age groups in the general population, in both the US and Ontario.

  6. Demographic changes following mechanical removal of exotic brown trout in an Intermountain West (USA), high-elevation stream (United States)

    Saunders, W. Carl; Budy, Phaedra E.; Thiede, Gary P.


    Exotic species present a great threat to native fish conservation; however, eradicating exotics is expensive and often impractical. Mechanical removal can be ineffective for eradication, but nonetheless may increase management effectiveness by identifying portions of a watershed that are strong sources of exotics. We used mechanical removal to understand processes driving exotic brown trout (Salmo trutta) populations in the Logan River, Utah. Our goals were to: (i) evaluate the demographic response of brown trout to mechanical removal, (ii) identify sources of brown trout recruitment at a watershed scale and (iii) evaluate whether mechanical removal can reduce brown trout densities. We removed brown trout from 2 km of the Logan River (4174 fish), and 5.6 km of Right Hand Fork (RHF, 15,245 fish), a low-elevation tributary, using single-pass electrofishing. We compared fish abundance and size distributions prior to, and after 2 years of mechanical removal. In the Logan River, immigration to the removal reach and high natural variability in fish abundances limited the response to mechanical removal. In contrast, mechanical removal in RHF resulted in a strong recruitment pulse, shifting the size distribution towards smaller fish. These results suggest that, before removal, density-dependent mortality or emigration of juvenile fish stabilised adult populations and may have provided a source of juveniles to the main stem. Overall, in sites demonstrating strong density-dependent population regulation, or near sources of exotics, short-term mechanical removal has limited effects on brown trout populations but may help identify factors governing populations and inform large-scale management of exotic species.

  7. Changing Demographics and Injury Profile of New Traumatic Spinal Cord Injuries in the United States, 1972-2014. (United States)

    Chen, Yuying; He, Yin; DeVivo, Michael J


    To document trends in the demographic and injury profile of new spinal cord injury (SCI) over time. Cross-sectional analysis of longitudinal data by injury years (1972-1979, 1980-1989, 1990-1999, 2000-2009, 2010-2014). Twenty-eight Spinal Cord Injury Model Systems centers throughout the United States. Persons with traumatic SCI (N=30,881) enrolled in the National Spinal Cord Injury Database. Not applicable. Age, sex, race, education level, employment, marital status, etiology, and severity of injury. Age at injury has increased from 28.7 years in the 1970s to 42.2 years during 2010 to 2014. This aging phenomenon was noted for both sexes, all races, and all etiologies except acts of violence. The percentage of racial minorities expanded continuously over the last 5 decades. Virtually among all age groups, the average education levels and percentage of single/never married status have increased, which is similar to the trends noted in the general population. Although vehicular crashes continue to be the leading cause of SCI overall, the percentage has declined from 47.0% in the 1970s to 38.1% during 2010 to 2014. Injuries caused by falls have increased over time, particularly among those aged ≥46 years. Progressive increases in the percentages of high cervical and motor incomplete injuries were noted for various age, sex, race, and etiology groups. Study findings call for geriatrics expertise and intercultural competency of the clinical team in the acute and rehabilitation care for SCI. This study also highlights the need for a multidimensional risk assessment and multifactorial intervention, especially to reduce falls and SCI in older adults.

  9. Problematic Gaming Behavior Among Finnish Junior High School Students: Relation to Socio-Demographics and Gaming Behavior Characteristics. (United States)

    Männikkö, Niko; Ruotsalainen, Heidi; Demetrovics, Zsolt; Lopez-Fernandez, Olatz; Myllymäki, Laura; Miettunen, Jouko; Kääriäinen, Maria


    Multiplatform digital media use and gaming have been increased in recent years. The aim of this study was to examine associations between sociodemographics and digital gaming behavior characteristics (i.e., gaming time, medium, and genres) with problematic gaming behavior in adolescents. A convenience sample of Finnish junior high school students (n = 560; mean age 14 years, ranging from 12 to 16 years) participated in the cross-sectional survey, of which, 83% (n = 465) reported having played digital games regularly. Sociodemographic data, different forms of digital media use, gaming behavior characteristics and problematic gaming behavior was assessed. Study participants spent on average one hour per day playing digital games; casual games (23.9%), shooting games (19.8%), and sport games (12.9%), were the most popular games among participants. By using regression analysis, a blended family structure and gaming time related positively to problematic gaming behavior. Preferences for game genres such as solo, Massively Multiplayer Online Role-Playing and strategy-management games were also positively associated with problematic use of digital games. These findings provide knowledge that can be utilized in the prevention of the possible negative consequences of digital gaming.

  10. Acknowledging and adapting to dietetic students' changing needs. (United States)

    Lordly, Daphne; MacLellan, Debbie


    Various societal influences have shaped the way dietetic students view and react to current educational situations. Students' perspectives were sought on conditions that caused stress in the educational environment, what they thought educators did not understand about them, and changes their faculty or preceptors had made to address their needs. Third- and fourth-year university students, interns in their final rotations, and master's degree students completed a questionnaire (n=284). Several stressors were identified: thinking about getting a job as a dietitian, lack of finances or debt, competing for internship positions, the ability to meet program demands, and envisioning the area in which they would specialize. The qualitative analysis highlighted gaps in understanding between students and educators. Gaps concerned student finances, the evaluation process, inflexible undergraduate and internship structures, competition among students, ineffective communication, and finding a balance between academics and other competing interests. A conflict exists between what students expect as part of their educational experience and what they actually experience. Students appreciated educators who engaged them in the learning process and recognized the realities of their lives.

  12. Effects of geological changes and climatic fluctuations on the demographic histories and low genetic diversity of Squaliobarbus curriculus in Yellow River. (United States)

    Zhou, Wei; Song, Na; Wang, Jun; Gao, Tianxiang


    The 104 samples of Squaliobarbus curriculus were collected from four localities in Yellow River and one region in Yangtze River. Analyses of the first hypervariable region of mitochondrial DNA control region of 555bp revealed only 15 polymorphism sites and defined 19 haplotypes. Low-to-moderate levels of haplotype diversity and low nucleotide diversity were observed in Yellow River populations (h=0.2529-0.7510, π=0.0712%-0.2197%). In contrast, Poyang Lake population showed high haplotype diversity and lower-middle nucleotide diversity (h=0.9636, π=0.5317%). Low genetic differentiation was estimated among Yellow River populations and significant level of genetic structure was detected between two rivers. Population genetic structure between two rivers was believed to be connected with geographical barriers and paleoclimatic events. The demographic history of S. curriculus in Yellow River examined by neutrality tests, mismatch distribution analysis, and Bayesian skyline analysis suggested a sudden and spatial population expansion dating to the Holocene. Climatic warming and changes of Yellow River course may have important effects on demographic facet of S. curriculus history. The same signal was also obtained on Poyang Lake population in late Pleistocene during the last interglacial period. During the period, the pronounced climatic change and the water system variation of PYL may have an important influence on the population. Copyright © 2016 Elsevier B.V. All rights reserved.

  13. Demographic consequences of increased winter births in a large aseasonally breeding mammal (Bos taurus) in response to climate change. (United States)

    Burthe, Sarah; Butler, Adam; Searle, Kate R; Hall, Stephen J G; Thackeray, Stephen J; Wanless, Sarah


    1. Studies examining changes in the scheduling of breeding in response to climate change have focused on species with well-defined breeding seasons. Species exhibiting year-round breeding have received little attention and the magnitudes of any responses are unknown. 2. We investigated phenological data for an enclosed feral population of cattle (Bos taurus L.) in northern England exhibiting year-round breeding. This population is relatively free of human interference. 3. We assessed whether the timing of births had changed over the last 60 years, in response to increasing winter and spring temperatures, changes in herd density, and a regime of lime fertilisation. 4. Median birth date became earlier by 1·0 days per year. Analyses of the seasonal distribution of calving dates showed that significantly fewer calves were born in summer (decline from 44% of total births to 20%) and significantly more in winter (increase from 12% to 30%) over the study period. The most pronounced changes occurred in winter, with significant increases in both the proportion and number of births. Winter births arise from conceptions in the previous spring, and we considered models that investigated climate and weather variables associated with the winter preceding and the spring of conceptions. 5. The proportion of winter births was higher when the onset of the plant growing season was earlier during the spring of conceptions. This relationship was much weaker during years when the site had been fertilised with lime, suggesting that increased forage biomass was over-riding the impacts of changing plant phenology. When the onset of the growing season was late, winter births increased with female density. 6. Recruitment estimates from a stage-structured state-space population model were significantly negatively correlated with the proportion of births in the preceding winter, suggesting that calves born in winter are less likely to survive than those born in other seasons. 7.

  14. Medical Student Perceptions of the Learning Environment in Medical School Change as Students Transition to Clinical Training in Undergraduate Medical School. (United States)

    Dunham, Lisette; Dekhtyar, Michael; Gruener, Gregory; CichoskiKelly, Eileen; Deitz, Jennifer; Elliott, Donna; Stuber, Margaret L; Skochelak, Susan E


    Phenomenon: The learning environment is the physical, social, and psychological context in which a student learns. A supportive learning environment contributes to student well-being and enhances student empathy, professionalism, and academic success, whereas an unsupportive learning environment may lead to burnout, exhaustion, and cynicism. Student perceptions of the medical school learning environment may change over time and be associated with students' year of training and may differ significantly depending on the student's gender or race/ethnicity. Understanding the changes in perceptions of the learning environment related to student characteristics and year of training could inform interventions that facilitate positive experiences in undergraduate medical education. The Medical School Learning Environment Survey (MSLES) was administered to 4,262 students who matriculated at one of 23 U.S. and Canadian medical schools in 2010 and 2011. Students completed the survey at the end of each year of medical school as part of a battery of surveys in the Learning Environment Study. A mixed-effects longitudinal model, t tests, Cohen's d effect size, and analysis of variance assessed the relationship between MSLES score, year of training, and demographic variables. After controlling for gender, race/ethnicity, and school, students reported worsening perceptions toward the medical school learning environment, with the worst perceptions in the 3rd year of medical school as students begin their clinical experiences, and some recovery in the 4th year after Match Day. The drop in MSLES scores associated with the transition to the clinical learning environment (-0.26 point drop in addition to yearly change, effect size = 0.52, p effect size = 0.14, p work-life balance and informal student relationships. There was some, but not complete, recovery in perceptions of the medical school learning environment in the 4th year. Insights: Perceptions of the medical school learning

  15. Alcohol policy enforcement and changes in student drinking rates in a statewide public college system: a follow-up study

    Directory of Open Access Journals (Sweden)

    Harris Sion K


    Full Text Available Abstract Background Heavy alcohol use among U.S. college students is a major contributor to young adult morbidity and mortality. The aim of this study was to examine whether college alcohol policy enforcement levels predict changes in student drinking and related behaviors in a state system of public colleges and universities, following a system-wide change to a stricter policy. Methods Students and administrators at 11 Massachusetts public colleges/universities completed surveys in 1999 (N of students = 1252, one year after the policy change, and again in 2001 (N = 1074. We calculated policy enforcement scores for each school based on the reports of deans of students, campus security chiefs, and students, and examined the correlations between perceived enforcement levels and the change in student drinking rates over the subsequent two year period, after weighting the 2001 data to adjust for demographic changes in the student body. Results Overall rates of any past-30-days drinking, heavy episodic drinking, and usual heavy drinking among past-30-days drinkers were all lower in 2001 compared to 1999. School-level analyses (N = 11 found deans' baseline reports of stricter enforcement were strongly correlated with subsequent declines in heavy episodic drinking (Pearson's r = -0.73, p = 0.011. Moreover, consistently high enforcement levels across time, as reported by deans, were associated with greater declines in heavy episodic drinking. Such relationships were not found for students' and security chiefs' reports of enforcement. Marijuana use did not rise during this period of decline in heavy drinking. Conclusions Study findings suggest that stronger enforcement of a stricter alcohol policy may be associated with reductions in student heavy drinking rates over time. An aggressive enforcement stance by deans may be an important element of an effective college alcohol policy.

  16. University students with learning disabilities advocating for change. (United States)

    Roer-Strier, D


    In recent decades Western psychology has conceptualized learning disabilities (LD) in terms of deficits and such related 'social emotional issues' as insecurity, low self-esteem and social isolation that can be rehabilitated through combined remedial teaching and psychological intervention. With increasing advocacy and legislation on behalf of people with disabilities in the US, UK and Australia, more resources are being made available to students with LD in institutions of higher education. Due to this increase in the quantity of services, written programmes and accommodations made to their needs, increased numbers of students with LD have been graduating successfully from institutions of higher education. This paper describes an option for treating students with LD that is based on a theoretical perspective that understands these students as an excluded population and emphasizes the importance of their empowerment. A project involving social work students with LD at Hebrew University in Jerusalem is presented as a case study. Case-study investigation, one of the common methods of qualitative research, explores social and human problems in their natural context. A 6-year evaluation of this project was conducted based on questionnaires, focus groups, documentation of all activities related to the project, in-depth interviews and outcome measures. The results suggest that the project developed in three stages: raising awareness, building partnerships, and lobbying for rights and services. Outcome measures indicate that the project was successful in lowering dropout rates and improving students' academic achievement. Analysis of interviews with students suggests that the project positively affected the students' perceptions by helping them reframe the social and emotional connotations of their learning disability. Students reported marked social and emotional change, including reduced stress and anxiety levels and increased self-esteem. Empowerment practices that are

  17. Serbian demographers on demography

    Directory of Open Access Journals (Sweden)

    Rašević Mirjana


    ageing were singled out the most as significant for examining in the immediate future. The inclusion of Stanovništvo on the Science Citation Information Journal List and expanding the circle of authors were the basic recommendations of the respondents regarding better quality of the journal. All interviewed experts mentioned various kinds of knowledge and characteristics necessary for demographers to posses in order to be successful. Contrary to the homogeneous opinion that a demographer should be a superior-researcher, a wide range of responses were given to the question regarding selecting the best indicator for determining the successfulness of researchers in the study of population. As many as eight out of ten interviewed experts believe population ageing is the greatest population challenge which Serbia is facing. However, a low level of consensus appeared among the demographers as regards the range of the political response. Namely, five experts declared they were pessimists in view of the possibilities for mitigating the challenge they singled out. On the contrary, five interviewed experts expressed optimism, as they believe in the economic development of Serbia, the possibilities of institutional adjustments to demographic changes, and/or in man and his rationality. Conclusion: Demographers in Serbia highly appreciate the discipline they belong to. At the same time they are strict critics and have high expectations in all matters dealing with demography.

  18. Climate Change Student Summits: A Model that Works (Invited) (United States)

    Huffman, L. T.


    The C2S2: Climate Change Student Summit project has completed four years of activities plus a year-long longitudinal evaluation with demonstrated positive impacts beyond the life of the project on both students and teachers. This presentation will share the lessons learned about implementing this climate change science education program and suggest that it is a successful model that can be used to scale up from its Midwestern roots to achieve measurable national impact. A NOAA Environmental Literacy grant allowed ANDRILL (ANtarctic geological DRILLing) to grow a 2008 pilot program involving 2 Midwestern sites, to a program 4 years later involving 10 sites. The excellent geographical coverage included 9 of the U.S. National Climate Assessment regions defined by the U.S. Global Change Research Program. Through the delivery of two professional development (PD) workshops, a unique opportunity was provided for both formal and informal educators to engage their classrooms/audiences in understanding the complexities of climate change. For maximum contact hours, the PD experience was extended throughout the school year through the use of an online grouphub. Student teams were involved in a creative investigative science research and presentation experience culminating in a Climate Change Student Summit, an on-site capstone event including a videoconference connecting all sites. The success of this program was based on combining multiple aspects, such as encouraging the active involvement of scientists and early career researchers both in the professional development workshops and in the Student Summit. Another key factor was the close working relationships between informal and formal science entities, including involvement of informal science learning facilities and informal science education leaders. The program also created cutting-edge curriculum materials titled the ELF, (Environmental Literacy Framework with a focus on climate change), providing an earth systems

  19. Changes in Taiwanese nursing student values during the educational experience. (United States)

    Lin, Yu-Hua; Liching Sung Wang; Yarbrough, Susan; Alfred, Danita; Martin, Pam


    Professional values are standards for action and provide a framework for evaluating behavior. This study examined changes in the professional values of nursing students between their entrance to and graduation from an undergraduate nursing program. A pre- and post-test design was employed. A convenience sample of 94 students from a university in Taiwan was surveyed. Data were collected from students during the sophomore and senior years. Total scores obtained for the revised Nurses Professional Values Scale during the senior year of the nursing program were significantly higher than upon program entry. The 'caring' subscale was scored highest at both program entry and graduation, but the pre- and post-test scores were not significantly different from each other. The students scored significantly higher on the 'professionalism' and 'activism' subscales at post-test than they did at pre-test. Professional values changed in a positive direction between the beginning of the student nurses' educational experience and their graduation. The results supported the premise that education had a positive effect on these students' professional values but causality could not be assumed.

  1. Middle School Students' Understandings About Anthropogenic Climate Change (United States)

    Golden, B. W.


    Given the complexity of the science involving climate change (IPCC, 2007), its lack of curricular focus within US K-12 schooling (Golden, 2009; Golden & Francis, 2013), and the difficulty in effecting conceptual change in science (Vosniadou, 2007), we sought to research middle school students' conceptions about climate change, in addition to how those conceptions changed during and as a result of a deliberately designed global climate change (GCC) unit. In a sixth grade classroom, a unit was designed which incorporated Argumentation-Driven Inquiry (Sampson & Grooms, 2010). That is, students were assigned to groups and asked to make sense of standard GCC data such as paleoclimate data from ice cores, direct temperature measurement, and Keeling curves, in addition to learning about the greenhouse effect in a modeling lesson (Hocking, et al, 1993). The students were then challenged, in groups, to create, on whiteboards, explanations and defend these explanations to and with their peers. They did two iterations of this argumentation. The first iteration focused on the simple identification of climate change patterns. The second focused on developing causal explanations for those patterns. After two rounds of such argumentation, the students were then asked to write (individually) a "final" argument which accounted for the given data. Interview and written data were analyzed prior to the given unit, during it, and after it, in order to capture complicated nuance that might escape detection by simpler research means such as surveys. Several findings emerged which promised to be of interest to climate change educators. The first is that many students tended to "know" many "facts" about climate change, but were unable to connect these disparate facts in any meaningful ways. A second finding is that while no students changed their entire belief systems, even after a robust unit which would seemingly challenge such, each student engaged did indeed modify the manner in which

  2. 'We are faced everywhere with a growing population': demographic change and the British state, 1955-64. (United States)

    O' Hara, Glen


    The early 1960s was a period of relative expansion for the welfare state, and the return to the use of planning techniques in macroeconomic policy. This has hitherto been explained by reference to a number of general causes. These have included party political electoral necessity, the need to gain popular support for the cold war by spreading the benefits of liberal capitalism, the power of welfare professionals, the growing realization that the post-war welfare state was not working as well as previously thought, and generational changes in politics and the civil service. Whilst not denying the importance of all these factors, this essay seeks to make clear the importance of another vital element in this story: the implications for the welfare state and the managed economy of the rise in the birth rate, and the perceived' population explosion', of the late 1950s and early 1960s. Statistical estimates are presented here that show just how large the implied expansion of the welfare state, and just how serious the pressure of a growing dependent population, would have been had the population predictions of the early 1930s proved to be accurate.

    To compare the impact of ageing on the GP and nursing rural and city workforce. Cohort analysis of Australian Bureau of Statistics census data. The data was used to examine the age distribution of the city and rural GP and nursing workforce; patterns of attrition for those 50 years and over; and the impact of changes in working hours. The rural GP and nursing workforce is significantly older than their city counterparts (pbaby boomer' generation making up 52% of city GPs but 59% of rural GPs in 2001. While a large proportion of city and rural GPs continued to work past the age of 65 years, rural GPs left the workforce at a significantly younger age than city doctors (pgeneration X' GPs were no more likely to work long hours than those in the city (pbaby boomers' continued to work long hours. Rural GPs are retiring faster than city GPs and strategies to attract rural GPs and nurses will be critical to ensure adequate rural health care and that current rural workforce shortage do not worsen.

  14. Prevalence, demographic and psychosocial correlates for school truancy among students aged 13-15 in the Association of Southeast Asian Nations (ASEAN) member states. (United States)

    Pengpid, Supa; Peltzer, Karl


    Truancy among adolescents may negatively affect the achievement of academic goals. The aim of the study was to investigate the prevalence and correlates of school truancy in the Association of Southeast Asian Nations (ASEAN) member states. The analysis included 28 419 school children aged 13-15 years from seven ASEAN member states that participated in the Global School-based Student Health Survey (GSHS) between 2007 and 2013. The overall prevalence of past 30 day truancy across six ASEAN countries (excluding Brunei) was 24.8%; ranging from below 20% in Myanmar, Thailand, and Vietnam to more than 30% in Brunei Darussalam, Indonesia, and the Philippines. In multivariable logistic regression analysis, socio-demographic factors (older age, being male, the experience of hunger), externalising behaviour (tobacco use, alcohol use, having been in a physical fight, being bullied, having sustained an injury), and lack of protective social-familial factors (lack of peer support and lack of parental or guardian support) were found to be associated with truancy. High rates of truancy were found in ASEAN member states calling for interventions aimed to reduce truancy considering identified associated factors.

  15. Medical student mental health 3.0: improving student wellness through curricular changes. (United States)

    Slavin, Stuart J; Schindler, Debra L; Chibnall, John T


    Medical education can have significant negative effects on the well-being of medical students. To date, efforts to improve student mental health have focused largely on improving access to mental health providers, reducing the stigma and other barriers to mental health treatment, and implementing ancillary wellness programs. Still, new and innovative models that build on these efforts by directly addressing the root causes of stress that lie within the curriculum itself are needed to properly promote student wellness. In this article, the authors present a new paradigm for improving medical student mental health, by describing an integrated, multifaceted, preclinical curricular change program implemented through the Office of Curricular Affairs at the Saint Louis University School of Medicine starting in the 2009-2010 academic year. The authors found that significant but efficient changes to course content, contact hours, scheduling, grading, electives, learning communities, and required resilience/mindfulness experiences were associated with significantly lower levels of depression symptoms, anxiety symptoms, and stress, and significantly higher levels of community cohesion, in medical students who participated in the expanded wellness program compared with those who preceded its implementation. The authors discuss the utility and relevance of such curricular changes as an overlooked component of change models for improving medical student mental health.

  16. Demographic modelling reveals a history of divergence with gene flow for a glacially tied stonefly in a changing post-Pleistocene landscape (United States)

    Hotaling, Scott; Muhlfeld, Clint C.; Giersch, J. Joseph; Ali, Omar; Jordan, Steve; Miller, Michael R.; Luikart, Gordon; Weisrock, David W.


    AimClimate warming is causing extensive loss of glaciers in mountainous regions, yet our understanding of how glacial recession influences evolutionary processes and genetic diversity is limited. Linking genetic structure with the influences shaping it can improve understanding of how species respond to environmental change. Here, we used genome-scale data and demographic modelling to resolve the evolutionary history of Lednia tumana, a rare, aquatic insect endemic to alpine streams. We also employed a range of widely used data filtering approaches to quantify how they influenced population structure results.LocationAlpine streams in the Rocky Mountains of Glacier National Park, Montana, USA.TaxonLednia tumana, a stonefly (Order Plecoptera) in the family Nemouridae.MethodsWe generated single nucleotide polymorphism data through restriction-site associated DNA sequencing to assess contemporary patterns of genetic structure for 11 L. tumana populations. Using identified clusters, we assessed demographic history through model selection and parameter estimation in a coalescent framework. During population structure analyses, we filtered our data to assess the influence of singletons, missing data and total number of markers on results.ResultsContemporary patterns of population structure indicate that L. tumana exhibits a pattern of isolation-by-distance among populations within three genetic clusters that align with geography. Mean pairwise genetic differentiation (FST) among populations was 0.033. Coalescent-based demographic modelling supported divergence with gene flow among genetic clusters since the end of the Pleistocene (~13-17 kya), likely reflecting the south-to-north recession of ice sheets that accumulated during the Wisconsin glaciation.Main conclusionsWe identified a link between glacial retreat, evolutionary history and patterns of genetic diversity for a range-restricted stonefly imperiled by climate change. This finding included a history of

    The objective of this study was to evaluate the association between the percep­tion of body image and the stages of behavioral changes related to physical activity among Physical Education Students. Two hundred thirty six students were included. We measured the perception of body image (silhouettes scale, the stages of changes in behavior related to physical activity using a questionnaire developed by Marcus et al., and socio-demographic variables (gender, age, parental education, marital status, course, employment situation, housing, period of study and income. We used descriptive analysis, chi-square test, Fischer’s exact test, crude and adjusted multinomial regression to estimate the odds ratio (OR and 95% confidence intervals (95% CI. The prevalence of physically inactive behavior was 18.2% for males and 23.9% for females. Dissatisfaction with body image was associated with the stages of behavioral changes in females, with women with physically inactive behavior having greater odds of experiencing dissatisfaction with their body image, both for underweight (OR: 9.69; 95% CI: 1.05-89.30 and overweight (OR: 5.49; 95% CI: 1.07-28.11 when compared with women who were satisfied with their body image. We suggest the development of in­terventions aimed at the adoption of regular physical activity in order to promote greater satisfaction with body image.

  18. Engaging Students In The Science Of Climate Change (United States)

    Rhew, R. C.; Halversen, C.; Weiss, E.; Pedemonte, S.; Weirman, T.


    Climate change is arguably the defining environmental issue of our generation. It is thus increasingly necessary for every member of the global community to understand the basic underlying science of Earth's climate system and how it is changing in order to make informed, evidence-based decisions about how we will respond individually and as a society. Through exploration of the inextricable interconnection between Earth's ocean, atmosphere and climate, we believe students will be better prepared to tackle the complex issues surrounding the causes and effects of climate change and evaluate possible solutions. If students are also given opportunities to gather evidence from real data and use scientific argumentation to make evidence-based explanations about climate change, not only will they gain an increased understanding of the science concepts and science practices, the students will better comprehend the nature of climate change science. Engaging in argument from evidence is a scientific practice not only emphasized in the Framework for K-12 Science Education and the Next Generation Science Standards (NGSS), but also emphasized in the Common Core State Standards for English Language Arts & Literacy in History/Social Studies and Science (CCSS). This significant overlap between NGSS and CCSS has implications for science and language arts classrooms, and should influence how we support and build students' expertise with this practice of sciences. The featured exemplary curricula supports middle school educators as they address climate change in their classrooms. The exemplar we will use is the NOAA-funded Ocean Sciences Sequence (OSS) for Grades 6-8: The ocean-atmosphere connection and climate change, which are curriculum units that deliver rich science content correlated to the Next Generation Science Standards (NGSS) Disciplinary Core Ideas and an emphasis on the Practices of Science, as called for in NGSS and the Framework. Designed in accordance with the latest

  19. Middle school students' conceptual change in global climate change: Using argumentation to foster knowledge construction (United States)

    Golden, Barry W.

    This research examined middle school student conceptions about global climate change (GCC) and the change these conceptions undergo during an argument driven instructional unit. The theoretical framework invoked for this study is the framework theory of conceptual change (Vosniadou, 2007a). This theory posits that students do not simply correct incorrect ideas with correct ones, but instead weigh incoming ideas against already existing explanatory frameworks, which have likely served the learner well to this point. The research questions were as follows: (1) What are the patterns of students' conceptual change in GCC? (a) What conceptions are invoked in student learning in this arena? (b) What conceptions are most influential? (c) What are the extra-rational factors influencing conceptual change in GCC? This research took place in an urban public school in a medium sized city in the southeastern United States. A sixth grade science teacher at Central Middle school, Ms. Octane, taught a course titled "Research Methods I., which was an elective science course that students took as part of a science magnet program. A unit was designed for 6th grade instruction that incorporated an Argument-Driven Inquiry (ADI) approach, centered on the subject matter of Global Climate change and Global Warming. Students were immersed in three separate lessons within the unit, each of which featured an emphasis upon creating scientific explanations based upon evidence. Additionally, each of the lessons placed a premium on students working towards the development of such explanations as a part of a group, with an emphasis on peer review of the robustness of the explanations proposed. The students were involved in approximately a two week unit emphasizing global climate change. This unit was based on an argumentation model that provided data to students and asked them to develop explanations that accounted for the data. The students then underwent a peer-review process to determine if

    Full Text Available The objective of this research has been to compare the levels of and to establish the connection between results of psychology students and their parents in relation to nationalism and cosmopolitanism and collectivism, and to horizontal and vertical individualism. In addition, an attempt has been made to define the contribution of socio-demographic variables, the importance of religion and the ideological orientation of the respondents along with collectivism/individualism in explaining the pronounced nature of nationalism and/or cosmopolitanism among the students and their parents. The research was carried out on a group of 200 students (26 male and 174 female and 296 parents (143 male and 153 female, all of Croatian nationality. Three questionnaires were applied: the Nationalism and Cosmopolitanism Scale (Čorkalo and Kamenov, 1999, the HVIC questionnaire on horizontal and vertical individualism and collectivism (Singelis et al., 1995 and a socio-demographic questionnaire. The results showed that parents of students express more marked nationalism and collectivism than their (adult children, while students express more marked cosmopolitanism and horizontal individualism than their parents. However, as far as vertical individualism is concerned, there is no difference between the average results of students and parents. The correlation between the collectivism and individualism of students and their mothers and fathers is lower than that between nationalism and cosmopolitanism. The set of socio-demographic predictors, the importance of religion, ideological orientations and collectivism/individualism more reliably foresee nationalism rather than cosmopolitanism, both in the parental and student sample. The type and contribution of the individual predictors are similar in both samples, with the exception of certain socio-demographic predictors that were shown to be significant in the parental, but not in the student sample. Apart from socio-demographic

    One of the strategies for the prevention of the obesity is the identification of critical periods of gain weight. Some studies confirm gain weight during the university period. The purpose of the present study was to determine the changes in the body weight of the university students in Navarre. Prospective cohort study. Public University of Navarre and the University of Navarre, in Pamplona. Study examined weight change among 452 students attending at university in Pamplona, during first and third course. Four hundred and fifty two students completed the questionnaire. Weight and height were measures and body mass index was calculated. The mean body weight increased 0,600 kg, 1,8 kg for males and no change in body weight was observed in female. 44,7 % of students gained weight (60,8 % of men and 36,8 % of women), and the gain weight was of 3,4 kg. University years are a critical factor for the gain weight, particularly males. Consideration of this, is necessary the development of effective weight gain prevention strategies during the university. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA.

    Sarah Pittaway


    Full Text Available Library roles with a unique focus on student or customer engagement are relatively new in the sector and Worcester is one of the first universities to recruit to this area. Rather than focusing on the relationship between engagement and learning, this role seeks to engage with students as partners and agents for change who are actively involved in evaluating, developing and delivering our library service. This article outlines some of our initial successes and impacts, which are already changing the way we interact with our student population. It will also cover some of the challenges faced along the way, particularly in delivering service change in the context of the radical new service model of The Hive.

  3. [The demographic potential of Russia]. (United States)

    Vishnevskii, A


    This is a general review of current demographic trends in Russia. The author analyzes the decline in population size that is taking place at the end of the twentieth century, and traces its origins as far back as the disturbances associated with World War I, the Communist revolution, and the civil war that followed it. Political repression during the Stalinist period and the tribulations experienced during World War II also contributed to the current demographic crisis. The author discusses the changes in migration patterns and the declining fertility and increasing mortality rates. The decline in life expectancy is also addressed. Some comparisons are made with the demographic situation in other European countries.

  4. Medical student changes in self-regulated learning during the transition to the clinical environment. (United States)

    Cho, Kenneth K; Marjadi, Brahm; Langendyk, Vicki; Hu, Wendy


    Self-regulated learning (SRL), which is learners' ability to proactively select and use different strategies to reach learning goals, is associated with academic and clinical success and life-long learning. SRL does not develop automatically in the clinical environment and its development during the preclinical to clinical learning transition has not been quantitatively studied. Our study aims to fill this gap by measuring SRL in medical students during the transitional period and examining its contributing factors. Medical students were invited to complete a questionnaire at the commencement of their first clinical year (T0), and 10 weeks later (T1). The questionnaire included the Motivated Strategies for Learning Questionnaire (MSLQ) and asked about previous clinical experience. Information about the student's background, demographic characteristics and first clinical rotation were also gathered. Of 118 students invited to participate, complete paired responses were obtained from 72 medical students (response rate 61%). At T1, extrinsic goal orientation increased and was associated with gender (males were more likely to increase extrinsic goal orientation) and type of first attachment (critical care and community based attachments, compared to hospital ward based attachments). Metacognitive self-regulation decreased at T1 and was negatively associated with previous clinical experience. Measurable changes in self-regulated learning occur during the transition from preclinical learning to clinical immersion, particularly in the domains of extrinsic goal orientation and metacognitive self-regulation. Self-determination theory offers possible explanations for this finding which have practical implications and point the way to future research. In addition, interventions to promote metacognition before the clinical immersion may assist in preserving SRL during the transition and thus promote life-long learning skills in preparation for real-world practice.

    Nurses need a sound education in research and evidence-based practice (EBP) to provide patients with optimal care, but current teaching methods could be more effective. To evaluate the changes in nursing students 1) perceptions of research and EBP, 2) confidence in research and EBP, and 3) interest in research participation after completing a course in research and EBP. A pre-post assessment design was utilized to compare changes in students. This project was conducted at a small, private liberal arts institution with Bachelor of Science (BSN) students. Two cohorts of third-year BSN students (Year 1 N=55, Year 2 N=54) who were taking a required, semester-long Nursing Research and EBP course. Students' perceptions of and confidence in research and EBP were assessed pre- and post-semester using the Confidence in Research and EBP survey, which contained 7 demographic items, 9 Research Perceptions items, and 19 Confidence in Research items (5-point Likert scale; 1=Not at all confident, 5=Extremely confident). Two years of data were collected and analyzed in SPSS v.24.0. Wilcoxon signed-ranks tests and Mann-Whitney-U tests were utilized to examine the data. Students had significant improvements in perceptions of and confidence in research and EBP (pnursing practice. Copyright © 2017. Published by Elsevier Ltd.

    The objective of the present survey was to study the dietary behavior of university students residing away from the family home. In this context, we (a) compared their dietary habits in two time periods, namely 2006 and 2016; and (b) explored the possible impact of gender on the behavioral changes in nutritional choices. A total of four hundred and five university students (2006, n = 242; 2016, n = 163) participated in the study. Dietary assessment was carried out using a qualitative Food Frequency Questionnaire, while data about demographic and lifestyle factors were also collected. Students’ dietary habits have been modified in a generally desirable direction, as reflected, e.g., in the elevated consumption of several plant-based foods. Gender was also significantly associated with Body Mass Index (BMI) and changes in dietary attitudes. Possible reasons for the transition towards healthier and more balanced dietary habits could involve the budgetary constraints facing Greece in the last decade, as well as increasing nutritional awareness and other socio-cultural factors characterizing this target group. A deeper understanding of these relations would be crucial to foster nutritional education and further enhance the effectiveness of health promotion campaigns. PMID:29320449

  9. The Perceptions of Change and Change Readiness in Junior and Senior Engineering & Technology Students (United States)

    Moler, Perry J.

    The purpose of this study was to understand what perceptions junior and senior engineering & technology students have about change, change readiness, and selected attributes, skills, and abilities. The selected attributes, skills, and abilities for this study were lifelong learning, leadership, and self-efficacy. The business environment of today is dynamic, with any number of internal and external events requiring an organization to adapt through the process of organizational development. Organizational developments affect businesses as a whole, but these developments are more evident in fields related to engineering and technology. Which require employees working through such developments be flexible and adaptable to a new professional environment. This study was an Explanatory Sequential Mixed Methods design, with Stage One being an online survey that collected individuals' perceptions of change, change readiness, and associated attributes, skills, and abilities. Stage Two was a face-to-face interview with a random sample of individuals who agreed to be interviewed in Stage One. This process was done to understand why students' perceptions are what they are. By using a mixed-method study, a more complete understanding of the current perceptions of students was developed, thus allowing external stakeholders' such as Human Resource managers more insight into the individuals they seek to recruit. The results from Stage One, one sample T-test with a predicted mean of 3.000 for this study indicated that engineering & technology students have a positive perceptions of Change Mean = 3.7024; Change Readiness Mean = 3.9313; Lifelong Learning Mean = 4.571; Leadership = 4.036; and Self-Efficacy Mean = 4.321. A One-way ANOVA was also conducted to understand the differences between traditional and non-traditional student regarding change and change readiness. The results of the ANOVA test indicated there were no significant differences between these two groups. The results

    Full Text Available Introduction: Fasting during Ramadan provides an opportunistic setting for smoking cessation intervention. Smokers find it easy to cease smoking during Ramadan due to the religion, cultural and environmental influences. This study aims to determine the changes in smoking behaviour during Ramadan among Malay Muslim male students who were current smokers. Methods: This is cross sectional study using self-administered questionnaire to evaluate the socio demographic characteristics and two main relevant religious perceptions on smoking (i.e. ‘Is smoking ‘haram’ and ‘Does smoking invalidate your fasting’. Fagerstrom Test for Nicotine Dependence (FTND questionnaire was used to evaluate smoking behaviour before and during Ramadan. The total FTND scores and the percentages according to FTDN items, before Ramadan and during Ramadan were compared to determine good or poor smoking behaviour changes. Results: The overall FTND scores and the percentage according to its items were significantly reduced. There were significant association between smoking behaviour changes during Ramadan and household income, nicotine dependence and perception that smoking is ‘haram’. The percentage of good smoking behaviour changes was higher among those with higher income, high nicotine dependence and those who are not aware that smoking is ‘haram’. Conclusion: There is a great potential in taking advantage of the Ramadan environment to encourage smoking cessation among Muslim smokers.

  15. Students' Reactions to Climate Change Adaptation Risks and Opportunities (United States)

    Thiel, M.; Grant, J. H.


    Objectives/Scope How undergraduate (UG) business students at a major public university in the Rocky Mountain region develop appreciation, and some understanding of physical and natural sciences causing climate change (CC) and their implications for society through examples drawn from the students' immediate and meaningful physical environments. Methods, Procedures, Process Three regional examples of ways in which CC impacts the lives of students on the local campus will provide practical approaches for students' environmentally responsible actions beyond the classroom. The cases from different industries will help UG students learn how they play critical roles in preventing and managing natural hazards, disaster management, ecology, development, famine, and secure livelihoods. Observations, Results, Conclusions Classroom discussions of "businesses' ecological responsibilities" in some remote location often fail to "connect" with students who have spent most of their lives within 300 miles of campus. However, when businesses in Asia are adding particulate to the atmosphere in the jet stream over the Pacific, and subsequently graying the local ski slopes, causing early melting and delaying the start of ski seasons, that is a different matter! However, more summer activities offer economic opportunities! A second example is found among the local entrepreneurial woodworkers who take "beetle kill" pine trees that are wildfire hazards and convert them into beautiful, creatively described "blue pine" furniture, interior beams, wall panels and table-top decorations. The "industrial scale" anaerobic digesters used in the "circular economy" of giant cheese factories, dairy farms and packing plants offer a third example for linking business to chemistry, engineering, and aesthetics (odor reduction).

  16. Migration, settlement change and health in post-apartheid South Africa: Triangulating health and demographic surveillance with national census data1 (United States)



    Background World population growth will be increasingly concentrated in the urban areas of the developing world; however, some scholars caution against the oversimplification of African urbanization noting that there may be “counter-urbanization” and a prevailing pattern of circular rural–urban migration. The aim of the paper is to examine the ongoing urban transition in South Africa in the post-apartheid period, and to consider the health and social policy implications of prevailing migration patterns. Methods Two data sets were analysed, namely the South African national census of 2001 and the Agincourt health and demographic surveillance system. A settlement-type transition matrix was constructed on the national data to show how patterns of settlement have changed in a five-year period. Using the sub-district data, permanent and temporary migration was characterized, providing migration rates by age and sex, and showing the distribution of origins and destinations. Findings The comparison of national and sub-district data highlight the following features: urban population growth, particularly in metropolitan areas, resulting from permanent and temporary migration; prevailing patterns of temporary, circular migration, and a changing gender balance in this form of migration; stepwise urbanization; and return migration from urban to rural areas. Conclusions Policy concerns include: rural poverty exacerbated by labour migration; explosive conditions for the transmission of HIV; labour migrants returning to die in rural areas; and the challenges for health information created by chronically ill migrants returning to rural areas to convalesce. Lastly, suggestions are made on how to address the dearth of relevant population information for policy-making in the fields of migration, settlement change and health. PMID:17676507

  17. Verbal Bullying Changes Among Students Following an Educational Intervention Using the Integrated Model for Behavior Change. (United States)

    Naidoo, Saloshni; Satorius, Benn K; de Vries, Hein; Taylor, Myra


    Bullying behavior in schools can lead to psychosocial problems. School-based interventions are important in raising student awareness, developing their skills and in planning to reduce bullying behavior. A randomized controlled trial, using a school-based educational intervention to reduce verbal bullying, was conducted among grade 10 students in 16 urban and rural schools in KwaZulu-Natal, South Africa in 2013. Baseline and postintervention questionnaires, developed using the Integrated Model for Behavior Change theoretical model, were used to assess changes in verbal bullying. Postintervention there were reduced verbal bullying experiences. Improved social norms and awareness of verbal bullying were associated with reduced verbal bullying experiences and behavior. Although less likely to bully others verbally, girls were more likely to experience verbal bullying. Students with no living father were more likely to bully others verbally. The study findings indicate that a school-based intervention can positively impact on verbal bullying experiences and behavior. © 2016, American School Health Association.

  19. Conceptual Change regarding middle school students' experience with Global Climate Change (United States)

    Golden, B. W.; Lutz, B.


    Given the complexity of the science involving climate change (IPCC, 2007), its lack of curricular focus within US K-12 schooling (Golden, 2009), and the difficulty in effecting conceptual change in science (Vosniadou, 2007), we sought to research middle school students' conceptions about climate change, in addition to how those conceptions changed during and as a result of a deliberately designed global climate change (GCC) unit. In a sixth grade classroom, a unit was designed which incorporated Argumentation-Driven Inquiry (Sampson & Grooms, 2010). That is, students were assigned to groups and asked to make sense of standard GCC data such as paleoclimate data from ice cores, direct temperature measurement, and Keeling curves, in addition to learning about the greenhouse effect in a modeling lesson (Hocking, et al, 1993). The students were then challenged, in groups, to create, on whiteboards, explanations and defend these explanations to and with their peers. They did two iterations of this argumentation. The first iteration focused on the simple identification of climate change patterns. The second focused on developing causal explanations for those patterns. After two rounds of such argumentation, the students were then asked to write (individually) a "final" argument which accounted for the given data. Interview and written data were analyzed prior to the given unit, during it, and after it, in order to capture complicated nuance that might escape detection by simpler research means such as surveys. Several findings emerged which promised to be of interest to climate change educators. The first is that many students tended to "know" many "facts" about climate change, but were unable to connect these disparate facts in any meaningful ways. A second finding is that while no students changed their entire belief systems, even after a robust unit which would seemingly challenge such, each student engaged did indeed modify the manner in which they discussed the

  20. [Trends of change in demographic indices of population in the area of oil and gas deposits of the republic of Kazakhstan]. (United States)

    Kenessaryiev, U I; Yerzhanova, A E; Kenessary, D U; Kenessary, A U

    According to assured resources of hydrocarbons the Republic of Kazakhstan (RK) is among ten largest oil countries in the world, trailing only some states of the Middle East, Latin America, as well Russia and the USA. Public health state is the one of most important indices of social development, the manifestation of the economic and sanitaryhygienic welfare, as well as national defense capability and cultural potential of the state. In relation with the intensive development of oil and gas fields the problems of environmental protection and healthcare of the population in these regions occur critically. Therefore, it causes keen interest both from the side of researches and practical health care workers. Rapid development of the oil and gas industry leads to changes in a medical and demographic situation of given regions that is related both with the natural migration of the population and other migratory processes. According to data of the Ministry of Energetics and natural resources of RK, the Karachaganak oil-gas condensate deposit is considered to be the one of the largest in the world. For the next 40 years, the field is becoming the stable financial donor of the country. Currently Karachaganak field is considered to be the one of the largest investment projects in Kazakhstan. The studied oil and gas condensate field is located in the Burlin district of West Kazakhstan region, which is 140 km far from the city of Uralsk and 160 km far from the city of Orenburg. The field was discovered in 1984.

  1. Personal and demographic factors and change of subjective indoor air quality reported by school children in relation to exposure at Swedish schools: a 2-year longitudinal study. (United States)

    Wang, Juan; Smedje, Greta; Nordquist, Tobias; Norbäck, Dan


    This paper studies changes in subjective indoor air quality (SIAQ) among school children and relates these data to repeated exposure measurements during a two-year follow-up period. Data on SIAQ and demographic information were gathered by a questionnaire sent to 1476 primary and secondary school pupils in 39 randomly selected schools at baseline and after two years (follow-up). Exposure measurements were applied after questionnaire data were collected at baseline and follow-up in approximately 100 classrooms. The arithmetic mean values for baseline and follow-up were: for indoor air temperature 23.6°C and 21.8°C and for outdoor air flow rate 5.4 L/s and 7.9L/s. Older children, those with atopy at baseline, and those in larger schools reported impaired SIAQ during follow-up. Installation of new ventilation systems, higher personal air flow rate and air exchange rate, and better illumination were associated with improved SIAQ. Higher CO2 levels were associated with impaired SIAQ. In conclusion, sufficient ventilation and illumination in classrooms are essential for the perception of good indoor air quality.

  2. Changes in use of cigarettes and non-cigarette alternative products among college students. (United States)

    Loukas, Alexandra; Batanova, Milena; Fernandez, Alejandra; Agarwal, Deepti


    The present study examined change in use of various smoked and smokeless non-cigarette alternative products in a sample of college students, stratified by current, or past 30-day, cigarette smoking status. Participants were 698 students from seven four-year colleges in Texas. Participants completed two waves of online surveys regarding tobacco use, knowledge, and attitudes, with 14 months between each wave. The most prevalent products used by the entire sample at Wave 1 were cigarettes, followed by hookah, cigars/cigarillos/little cigars, and electronic cigarettes (e-cigarettes). At Wave 2, prevalence of e-cigarette use surpassed use of cigars/cigarillos/little cigars. Snus and chew/snuff/dip were relatively uncommon at both waves. Examination of change in use indicated that e-cigarette use increased across time among both current cigarette smokers and non-cigarette smokers. Prevalence of current e-cigarette use doubled across the 14-month period to 25% among current smokers and tripled to 3% among non-cigarette smokers. Hookah use also increased across time, but only among non-cigarette smokers, whereas it decreased among current cigarette smokers. Use of all other non-cigarette alternatives remained unchanged across time. Logistic regression analysis was used to examine the socio-demographic predictors of Wave 2 e-cigarette use, the only product that increased in use among both current cigarette smokers and non-cigarette smokers. Results indicated that Wave 1 current cigarette use and Wave 1 current e-cigarette use, but not gender, age, or race/ethnicity, were significantly associated with Wave 2 e-cigarette use. Findings underscore the need to track changes in the use of non-cigarette alternatives and call for additional research examining the factors contributing to change in use.

  3. Vertebrates population response to the climatic change - pertinence of the environmental indicators and influence of the demographic strategies and consequences for the biodiversity dynamic

    International Nuclear Information System (INIS)

    Weimerskirch, H.


    There is a growing interest and major challenge to understand the way environmental variability and climatic change have affected and will affect ecosystems and populations. Long-term records of population parameters of vertebrates are rare, but invaluable to address this challenge. The network CLIMPOP brings together French researchers working with long term data collected on individually marked animals to study the effects of climate change on a range of vertebrate populations (reptiles, birds and mammals) and standardised methods to link climatic factors and demographic parameters. The funding from GICC-IFB has allowed the CLIMPOP group to hire a post doc bridging methodologists and ecologists, organize a workshop and support field studies. Several analyses on a series of vertebrates have been carried out on the link between large-scale and small-scale climatic factors and population dynamics. In addition the CLIMPOP group has carried out a major methodological paper reviewing statistical models and procedures to study the influence of climate on vital rates based on the analysis of individual monitoring data, to identify potential pitfalls in the utilization of these models and procedures, to review published papers in which the influence of climatic variation on survival probability in vertebrate populations has been addressed, to evaluate whether the results from these studies are relevant and to draw practical recommendations to efficiently address effects of climate effects on vital rates in natural vertebrate populations. This evaluation raised six potential methodological issues and indicates that so far most of the studies found in the ecological literature can be considered as being useful for the purpose of generating hypothesis rather than for that of obtaining solid evidence for the impact of climatic factors on vital rates.

  4. A Climate Change Minor that gets Physics Students talking to Philosophy Students (United States)

    Running, S. W.; Phear, N.


    We started a Climate Change Studies Minor at the University of Montana in 2008. The curriculum is divided into three Sections: Science, Society and Solutions. Faculty from at least 8 different departments offer courses. The Science curriculum is what you would expect, however we worked hard to build the Society Section to include courses in political science, ethics, economics, communication, international policy. The Solutions Section introduces a variety of sustainability, renewable energy and green business courses, and internships and practicums with local organizations and businesses. Our goal has been a Minor that can be taken by students from any major on campus. The high point for me is watching the AGU type geeks interacting with philosophy majors, business students, and pre-law students.

  7. Contemplating the Future: Building Student Resilience in Climate Change Education (United States)

    Allison, E.


    Climate change research has largely focused on the biophysical, economic, and political aspects of the phenomenon, its projected impacts, and the possibilities for adaptation (Carey et al. 2014; Castree et al. 2014). In the classroom, too, climate change is generally presented as a scientific, technological, political, and economic challenge. However, defining climate change as physical challenge, divorced from its cultural causes and responses, forecloses some pathways of inquiry and limits the possibilities for adaptation (Adger et al. 2013). Recent perspectives by the environmental historian Mark Carey and colleagues (2014) and by the geographer Noel Castree and colleagues (2014) contend that ethnographic, narrative, social scientific, and humanistic insights are necessary additions to the climate change policy process and can contribute to deliberate, resilient responses to climate change. Among the humanistic insights needed are strategies and practices to maintain fortitude and persistence in the midst of dispiriting ecological trends. Students facing the "gloom and doom" of climate change data in environmental studies courses can experience negative states of mind such as denial, despair, burnout, and grief. Emerging research, however, demonstrates how contemplative practice can shift consciousness and promote resilience. Contemplative practices are those that consciously direct calm, focused attention. Such practices can build internal resilience, by promoting a greater sense of calm and well-being, decreasing stress, and sharpening focus and concentration. In addition, contemplative practices improve relationships with other people, through increasing compassion and flexibility in thinking. They also strengthen relationships with the surrounding world by increasing our ability to question, explore, and cope with rapid change and complexity. This presentation provides a context for incorporating contemplative practices, including mindfulness exercises

  8. Cancer awareness changes after an educational intervention among undergraduate students. (United States)

    Hwang, Lih-Lian


    The objectives of this study are to assess undergraduate awareness of cancer risk factors, prevention strategies, and warning signs and to evaluate whether an educational intervention increases cancer awareness. This study adopts a nonequivalent control group pretest-posttest design. Of the 386 students who completed the pretest, only 35-39 % identified low fruit and vegetable intake, being overweight, and physical inactivity as cancer risk factors, and cancer warning signs. After the educational intervention, the analysis of variance of changes from baseline (the pretest score) for all four experimental groups were all significantly higher than those of the two control groups (p ≤.001), except for the change of the retention test score from the pretest score for experimental group 3. This study highlights the need to improve undergraduates' cancer awareness and the effectiveness of educational intervention.

  13. Effectiveness of a poverty simulation in Second Life®: changing nursing student attitudes toward poor people. (United States)

    Menzel, Nancy; Willson, Laura Helen; Doolen, Jessica


    Social justice is a fundamental value of the nursing profession, challenging educators to instill this professional value when caring for the poor. This randomized controlled trial examined whether an interactive virtual poverty simulation created in Second Life® would improve nursing students' empathy with and attributions for people living in poverty, compared to a self-study module. We created a multi-user virtual environment populated with families and individual avatars that represented the demographics contributing to poverty and vulnerability. Participants (N = 51 baccalaureate nursing students) were randomly assigned to either Intervention or Control groups and completed the modified Attitudes toward Poverty Scale pre- and post-intervention. The 2.5-hour simulation was delivered three times over a 1-year period to students in successive community health nursing classes. The investigators conducted post-simulation debriefings following a script. While participants in the virtual poverty simulation developed significantly more favorable attitudes on five questions than the Control group, the total scores did not differ significantly. Whereas students readily learned how to navigate inside Second Life®, faculty facilitators required periodic coaching and guidance to be competent. While poverty simulations, whether virtual or face-to-face, have some ability to transform nursing student attitudes, faculty must incorporate social justice concepts throughout the curriculum to produce lasting change.

  14. Changes in Student Science Interest from Elementary to Middle School (United States)

    Coutts, Trudi E.

    This study is a transcendental phenomenological study that described the experience of students’ interest in science from elementary school through middle school grades and the identification of the factors that increase or decrease interest in science. Numerous researchers have found that interest in science changes among children and the change in interest seems to modulate student motivation, which ultimately leads to fewer children choosing not only science classes in the future but science careers. Research studies have identified numerous factors that affect student interest in science; however, this study incorporated the lived experience of the child and looked at this interest in science through the lens of the child. The study design was a collective cross-case study that was multi-site based. This study utilized a sample of children in fifth grade classes of three different elementary schools, two distinct seventh grade classes of different middle schools, and ninth grade children from one high school in the State of Illinois. The phenomenon was investigated through student interviews. The use of one-on-one semi-structured interviews limited to 45 minutes in length provided the researcher with data of each child’s description of science interest. All interviews were audio- recorded and transcribed verbatim. The data was collected and analyzed in order to identify themes, and finally checked for validity. The most significant findings of this study, and possible factors contributing to science interest in children as they progress from elementary to high school, were those findings relating to hands-on activities, the degree to which a student was challenged, the offering of new versus previously studied topics in the curriculum, the perceived relevance of the curricular materials to personal life, and the empowerment children felt when they were allowed to make choices related to their learning experiences. This study’s possible implications for

    Full Text Available As a result of conducting a 45 minute-long seminar on the principles, state of use, advantages, and disadvantages of nuclear power generation for Korean elementary, middle, and high school students, the levels of perception including the necessity (p<0.017, safety (p<0.000, information acquisition (p<0.000, and subjective knowledge (p<0.000, objective knowledge (p<0.000, attitude (p<0.000, and behavior (p<0.000 were all significantly higher. This indicates that education can be effective in promoting widespread social acceptance of nuclear power and its continued use. In order to induce behavior change toward positive judgments on nuclear power generation, it is necessary to focus on attitude improvement while providing the information in all areas related to the perception, knowledge, attitude, and behavior. Here, the positive message on the convenience and the safety of nuclear power generation should be highlighted.

  8. Demograficheskie izmenenija v Germanii i novaja territorial'naja struktura starenija [Demographic change in Germany and reversal of spatial ageing patterns

    Directory of Open Access Journals (Sweden)

    Swiaczny Frank


    Full Text Available The paper presents the result of a spatial analysis considering the effect of demographic ageing and ageing-in-place processes in Germany according to spatially differentiated ageing patterns among urban, sub-urban and rural counties up to 2025. As to the latest official population forecast counties of urban core regions will undergo a slower ageing process than other types of counties, resulting in a reversal of ageing patterns. Urban core areas in this analysis will gain demographically from their net migration surplus while suburban housing locations of the past will be no longer able to attract enough young migrants to compensate for their now rapidly ageing baby boomer generation. The process presented is typical for the fate of (suburban housing areas with homogenous populations under conditions of ageing and shrinking if spatial mobility in ageing population groups is declining.

  10. Predictors of student performance on the Pharmacy Curriculum Outcomes Assessment at a new school of pharmacy using admissions and demographic data. (United States)

    Gillette, Chris; Rudolph, Michael; Rockich-Winston, Nicole; Blough, Eric R; Sizemore, James A; Hao, Jinsong; Booth, Chris; Broedel-Zaugg, Kimberly; Peterson, Megan; Anderson, Stephanie; Riley, Brittany; Train, Brian C; Stanton, Robert B; Anderson, H Glenn

    To characterize student performance on the Pharmacy Curriculum Outcomes Assessment (PCOA) and to determine the significance of specific admissions criteria and pharmacy school performance to predict student performance on the PCOA during the first through third professional years. Multivariate linear regression models were developed to study the relationships between various independent variables and students' PCOA total scores during the first through third professional years. To date, four cohorts have successfully taken the PCOA examination. Results indicate that the Pharmacy College Admissions Test (PCAT), the Health Science Reasoning Test (HSRT), and cumulative pharmacy grade point average were the only consistent significant predictors of higher PCOA total scores across all students who have taken the exam at our school of pharmacy. The school should examine and clarify the role of PCOA within its curricular assessment program. Results suggest that certain admissions criteria and performance in pharmacy school are associated with higher PCOA scores. Copyright © 2016 Elsevier Inc. All rights reserved.

  11. Parental mediation of adolescent media use and demographic factors as predictors of Kenyan high school students' exposure to sexual content in television. (United States)

    Ngula, Kyalo wa; Mberia, Hellen K; Miller, Ann Neville


    Research in Western nations suggests that parents' involvement in their children's media use can make a difference in how adolescents select, process and respond to sexual television messages. Little or no published research has investigated this issue in sub-Saharan Africa, even though adolescents and young adults remain among the groups at highest risk for HIV transmission. This study investigated the relationship between Kenyan adolescents' level of exposure to sexual television content and their parents' mediation of their television use. A cluster sample of 427 Nairobi public high school students was surveyed regarding parental mediation of their media use and their intake of sexual television content. Co-viewing with opposite sex friends was associated with higher intake of sexual TV content. This relationship was stronger among boarding school students than among day school students. Parental mediation and co-viewing variables predicted three times as much variance among boarding than among day school students.

  12. Can Completing a Mental Health Nursing Course Change Students' Attitudes? (United States)

    Hastings, Todd; Kroposki, Margaret; Williams, Gail


    Nursing program graduates rarely choose mental health nursing as a career. A quasi-experimental study was conducted to examine attitudes of 310 nursing students towards persons with mental illness. Students completed surveys on the first and last days of their program's psychiatric mental health nursing course. The pre- and post-test survey analysis indicated that students improved their attitude, knowledge and preparedness to care for persons with mental illness. However, students maintained little interest in working as a mental health nurse. Modifications in mental health nursing courses could be made to improve students' interest in choosing a career in mental health nursing.

  15. Longitudinal Effects of Student-Perceived Classroom Support on Motivation - A Latent Change Model. (United States)

    Lazarides, Rebecca; Raufelder, Diana


    This two-wave longitudinal study examined how developmental changes in students' mastery goal orientation, academic effort, and intrinsic motivation were predicted by student-perceived support of motivational support (support for autonomy, competence, and relatedness) in secondary classrooms. The study extends previous knowledge that showed that support for motivational support in class is related to students' intrinsic motivation as it focused on the developmental changes of a set of different motivational variables and the relations of these changes to student-perceived motivational support in class. Thus, differential classroom effects on students' motivational development were investigated. A sample of 1088 German students was assessed in the beginning of the school year when students were in grade 8 ( Mean age = 13.70, SD = 0.53, 54% girls) and again at the end of the next school year when students were in grade 9. Results of latent change models showed a tendency toward decline in mastery goal orientation and a significant decrease in academic effort from grade 8 to 9. Intrinsic motivation did not decrease significantly across time. Student-perceived support of competence in class predicted the level and change in students' academic effort. The findings emphasized that it is beneficial to create classroom learning environments that enhance students' perceptions of competence in class when aiming to enhance students' academic effort in secondary school classrooms.

  18. Students' beliefs, attitudes, and conceptual change in a traditional and a constructivistic high school physics classroom (United States)

    Adams, April Dean

    In this study, the relationships between student beliefs about the nature of science, student attitudes, and conceptual change about the nature of forces were investigated within a traditional and within a constructivistic high school physics classroom. Students in both classrooms were honors students taking a first year high school physics course and were primarily white and middle to upper SES. Students in the traditional classroom were all high ability juniors, and physics instruction was integrated with pre-calculus. Students in the constructivistic classroom were a mixture of juniors and seniors. Due to the interrelated nature of these factors and the complexity of their interactions, a naturalistic inquiry design was chosen. The data sources included videotape of 7-9 weeks of instruction; analysis of the videotapes using the Secondary Teacher Analysis Matrix (Gallagher & Parker, 1995); field notes; pretest/posttest assessment with the Force Concept Inventory (Hestenes, Wells, & Swackhammer, 1992); student responses from the Views on Science-Technology-Society questionnaire (Aikenhead & Ryan, 1992), the Questionnaire for the Assessment of a Science Course (Chiappetta, 1995), and the Constructivist Learning Environment Survey (Taylor, Fraser, & White, 1994); student interviews; and teacher interviews. In the traditional classroom, (a) students did not think that physics was relevant to everyday experiences; (b) high conceptual change students were more likely to have an angular world view (Cobern, 1993) and have views more similar to the teacher's about the nature of science; and (c) high conceptual change students were able to develop an internally consistent understanding of the content; however, that content appeared to be isolated knowledge in some students. In the constructivistic classroom, (a) students saw physics as relevant and useful; (b) there was no difference in world view or agreement with the teacher's views on the nature of science between high

  19. Measuring changes in perception using the Student Perceptions of Physician-Pharmacist Interprofessional Clinical Education (SPICE) instrument. (United States)

    Zorek, Joseph A; MacLaughlin, Eric J; Fike, David S; MacLaughlin, Anitra A; Samiuddin, Mohammed; Young, Rodney B


    The Student Perceptions of Physician-Pharmacist Interprofessional Clinical Education (SPICE) instrument contains 10 items, 3 factors (interprofessional teamwork and team-based practice, roles/responsibilities for collaborative practice, and patient outcomes from collaborative practice), and utilizes a five-point response scale (1 = strongly disagree, 5 = strongly agree). Given the SPICE instrument's demonstrated validity and reliability, the objective of this study was to evaluate whether it was capable of measuring changes in medical (MS) and pharmacy students' (PS) perceptions following an interprofessional education (IPE) experience. In this prospective cohort study, MS and PS completed the SPICE instrument before and after participation in a predefined IPE experience. Descriptive statistics were used to characterize students and pre-post responses. Independent samples t tests and Fisher's Exact tests were used to assess group difference in demographic variables. Mann Whitney U tests were used to assess between-group differences in item scores. Wilcoxon Signed-Rank tests were used to evaluate post-participation changes in item scores. Spearman correlations were calculated to assess associations between ordinal demographic variables and item scores, and whether the number of clinic visits completed was associated with post-test responses. Paired samples t tests were used to calculate mean score changes for each of the factors. Thirty-four MS and 15 PS were enroled. Baseline differences included age (25.3. ± 1.3 MS vs. 28.7 ± 4.4 PS; p = 0.013), years full-time employment (0.71 ± 0.97 MS vs. 4.60 ± 4.55 PS; p impact of teamwork on patient satisfaction (3.72 vs. 4.34; p location for IPE (4.06 vs. 4.34; p = 0.002). Significant increases were observed for all three factors (teamwork, p = 0.003; roles/responsibilities and patient outcomes, p < 0.001). This study demonstrated the SPICE instrument's ability to measure

    Full Text Available The aim of the study was to determine the infl uence of characteristics such as sex, place of origin and fi nancial situation on the preferences and behaviour of students on the dairy products market. The analysis was based on primary data from a survey, conducted among 200 students of the University of Life Sciences in Poznan. It was found that all the characteristics differentiate the behaviour of the students, but the greatest eff ect was observed in the case of sex. Women consume dairy products more often, and when it comes to consumption of milk they choose low-fat products. For women the most important are special off ers and nutrient contents, while male students choose dairy products often guided by their price. The place of origin mainly aff ected the frequency of milk consumption: the respondents, who come from villages and smaller towns declared the most frequent consumption. The fi nancial situation mainly infl uenced the consumption of dairy products: richer students consume more dairy products. When purchasing they pay attention mainly to the taste and brand of the products.

  3. Changing Student Attitudes using Andes, An Intelligent Homework System (United States)

    van de Sande, Brett; Vanlehn, Kurt; Treacy, Don; Shelby, Bob; Wintersgill, Mary


    The size of introductory physics lectures often inhibits personal homework assistance and timely corrective feedback. Andes, an intelligent homework help system designed for two semesters of introductory physics, can fill this need by encouraging students to use sound problem solving techniques and providing immediate feedback on each step of a solution. On request, Andes provides principles-based hints based on previous student actions. A multi-year study at the U.S. Naval Academy demonstrates that students using Andes perform better than students working the same problems as graded pencil and paper homeworks. In addition, student attitude surveys show that Andes is preferred over other homework systems. These findings have implications for student attitudes toward, and mastery of, physics.

  12. Changes in rates of capture and demographics of Myotis septentrionalis (Northern Long-eared Bat) in Western Virginia before and after onset of white-nose syndrome (United States)

    Reynolds, Richard J.; Powers, Karen E.; Orndorff, Wil; Ford, W. Mark; Hobson, Christopher S.


    Documenting the impacts of white-nose syndrome (WNS) on demographic patterns, such as annual survivorship and recruitment, is important to understanding the extirpation or possible stabilization and recovery of species over time. To document demographic impacts of WNS on Myotis septentrionalis (Northern Long-eared Bat), we mistnetted at sites in western Virginia where Northern Long-eared Bats were captured in summer before (1990–2009) and after (2011–2013) the onset of WNS. Our mean capture rates per hour, adjusted for area of net and sampling duration, declined significantly from 0.102 bats/ m2/h before WNS to 0.005 bats/m2/h (-95.1%) by 2013. We noted a time lag in the rate of decline between published data based on bats captured during the swarming season and our summer mist-netting captures from the same geographic area. Although proportions of pregnant or lactating females did not vary statistically in samples obtained before and after the onset of WNS, the proportion of juvenile bats declined significantly (-76.7%), indicating that the viability of Northern Long-eared Bats in western Virginia is tenuous.

  13. A retrospective case report on demographic changes of learners at a school for children with Autism Spectrum Disorder in the Gauteng Province

    Directory of Open Access Journals (Sweden)

    Sumari van Biljon


    Full Text Available Limited research has been published about the demographic characteristics of children with Autism Spectrum Disorder (ASD in South Africa. Describing the profiles of learners from a school for children with ASD may contribute to local knowledge in the field. A retrospective comparative design was utilised to compare the demographic characteristics of learners over two time intervals: 1992-2002 (Group 1, n=32 and 2003-2014 (Group 2, n=109. A total of 141 historical admission records in paper-based files were reviewed. Results indicated that there is a large male gender bias (8.4:1 in learners, which increased over the years. The age of the child when parents first became concerned and the age at diagnosis and assessment at school increased over both time periods. There was also an increase in the diversity of home languages after 2002. Parental qualifications decreased, but social class improved in recent years. The low qualification of a mother was associated with an advanced age of the child at school entry. The data serves as a point of reference for future studies about the characteristics of school children with ASD in South Africa.

  14. The effect of fifth grade science teachers' pedagogical content knowledge on their decision making and student learning outcomes on the concept of chemical change (United States)

    Ogletree, Glenda Lee

    This study investigated the science pedagogical content knowledge (PCK) among teachers as they taught the concept of chemical change to fifth grade students. The purpose was to identify teachers' PCK and its impact in middle grade science classrooms. A second purpose was to investigate the possible relationship of teachers' science PCK to teacher actions and student learning outcomes in the classroom. The instruments used to capture PCK were background and demographic information, Content Representations (CoRe), and Professional and Pedagogical experience Repertoire (PaP-eR). The study investigated CoRe and PaP-eR with seven classroom teachers as they planned and taught chemical change to fifth grade students. Four levels of a Pedagogical Content Knowledge rubric were used to describe varying levels of PCK. The four levels were content knowledge of chemical change; knowledge of students' thinking; knowledge of how to represent chemical change to promote student learning; and professional development, collaboration, and leadership roles in science. The Reformed Teaching Observation Protocol (RTOP) described and evaluated science teaching performance levels of the teachers. In this study, 176 students were assessed to determine understanding of chemical change. There was a significant correlation between teachers' PCK scores and student achievement. The study also determined that a significant correlation existed between teachers' PCK scores and their RTOP scores revealing that RTOP scores could be predictors of PCK. Through this approach, understandings of PCK emerged that are of interest to university preservice preparation programs, research in understanding effective teachers and teaching, and the planning and implementation of professional development for teachers of science with middle grade students.

  16. Suicidal behaviors among Moroccan school students: prevalence and association with socio-demographic characteristics and psychoactive substances use: a cross-sectional study. (United States)

    Zarrouq, Btissame; Bendaou, B; Elkinany, S; Rammouz, I; Aalouane, R; Lyoussi, B; Khelafa, S; Bout, A; Berhili, N; Hlal, H; Nejjari, C; El Rhazi, K


    Suicidal behavior is a major cause of injury and death worldwide, especially among adolescents and young adults. Few studies have tackled this issue in the Arab world. The present study investigated the prevalence and the risk factors of suicidal behaviors among Moroccan school students. From April 2012 to November 2013, a cross-sectional study was conducted in the North-Centre region of Morocco among students in public secondary schools selected using stratified cluster random sampling. The data were collected via anonymous self-administered questionnaires. The Mini International Neuropsychiatric Interview was used in its Moroccan Colloquial Arabic version to assess suicidality according to the DSM-IV criteria. A total of 3020 students (53 % boys) aged 11-23 years (average age = 16 ± 2.1 years) were included in the study. The prevalence of suicide ideation, suicide planning and suicide attempts during the last month were 15.7, 6.3, and 6.5 % respectively. Univariate analyses demonstrated that suicidal behaviors followed different epidemiological patterns. According to the multivariate analyses, the risk factors for all suicidal behaviors among Moroccan school students were the female gender, middle school level, urban locations, low family income, parents' divorce, tobacco consumption and psychoactive substances (alcohol and cannabis) use. The intervention of preventive programs has become an emergency to overcome the issue of suicidality in Morocco. Further researches on adolescents' suicidal behaviors are suggested to update temporal data and assess the effectiveness of potential interventions.

  1. High school student's motivation to engage in conceptual change-learning in science (United States)

    Barlia, Lily


    This study investigated motivational factors that are related to engaging in conceptual change learning. While previous studies have recognized the resistance of students' scientific conception to change, few have investigated the role that non-cognitive factors might play when students are exposed to conceptual change instruction. Three research questions were examined: (a) What instructional strategies did the teacher use to both promote students' learning for conceptual change and increase their motivation in learning science? (b) What are the patterns of students' motivation to engage in conceptual change learning? And (c) what individual profiles can be constructed from the four motivational factors (i.e., goals, values, self-efficacy, and control beliefs) and how are these profiles linked to engagement (i.e., behavioral and cognitive engagement) in conceptual change learning of science? Eleven twelfth grade students (senior students) and the teacher in which conceptual change approach to teaching was used in daily activities were selected. Data collection for this study included student's self-reported responses to the Motivated Strategies for Learning Questionnaire (MSLQ), classroom observation of students and the teacher, and structured interviews. Analysis of these data resulted in a motivational factor profile for each student and cross case analysis for entire group. Results from this study indicate that each student has different motivation factors that are mostly influenced individual student to learn science. Among these motivation factors, task value and control beliefs were most important for students. The implication of these findings are that teachers need to encourage students to find learning for conceptual change a valuable task, and that students need to find applications for their new conceptions within their everyday lives. In addition, teachers need to encourage students to develop learning strategies for conceptual understanding

  7. Considering Students' Out-of-School Lives and Values in Designing Learning Environments for Climate Change (United States)

    Walsh, E.; Tsurusaki, B.


    What are the implications of social controversy for the teaching and learning of climate change science? How do the political dimensions of this controversy affect learners' attitudes towards and reasoning about climate change and climate science? Case studies from a pilot enactment of an ecological impacts of climate change curriculum explore these questions by describing how five high school students' understandings of climate change science developed at the intersection of political and scientific values, attitudes, and ways of knowing. Case studies combine qualitative, ethnographic methods including interviews and classroom video observations with quantitative pre/post-assessments of student conceptual understandings and weekly surveys of student engagement. Data indicate that students had initial perceptions of climate change informed by the media and their families—both supporting and rejecting the scientific consensus—that influenced how they engaged with the scientific evidence. While students who were initially antagonistic to anthropogenic climate change did develop conceptual understandings of the scientific evidence for human-influences on climate change, this work was challenging and at times frustrating for them. These case studies demonstrate the wide range of initial attitudes and understandings that students bring to the study of climate change. They also demonstrate that it is possible to make significant shifts in students' understandings of climate change science, even in students who were initially resistant to the idea of anthropogenic climate change. Finally, multiple case studies discuss ways that the learning that occurred in the classroom crossed out of the classroom into the students' homes and family talk. This work highlights how learners' pathways are shaped not only by their developing understanding of the scientific evidence but also by the political and social influences that learners navigate across the contexts of their lives

  8. Changing Minds about the Changing Climate: a Longitudinal Study of the Impacts of a Climate Change Curriculum on Undergraduate Student Knowledge and Attitudes. (United States)

    Burkholder, K. C.; Mooney, S.


    In the fall of 2013, 24 sophomore students enrolled in a three-course Learning Community entitled "The Ethics and Science of Climate Change." This learning community was comprised of two disciplinary courses in environmental ethics and environmental science as well as a seminar course in which the students designed and delivered climate change education events in the community beyond campus. Students were surveyed prior to and upon completion of the semester using a variant of the Yale Climate Literacy Survey in order to assess their knowledge of and attitudes towards climate change. An analysis of those survey results demonstrated that the non-traditional curriculum resulted in significant improvements that extended beyond disciplinary knowledge of climate change: the student attitudes about climate change and our cultural response to the issues associated with climate change shifted as well. Finally, a third administration of the survey (n=17) plus follow up interviews with 10 of those original students conducted during the students' senior year in 2016 suggest that the changes that the students underwent as sophomores were largely retained.

  10. Climate Change Professional Development Approaches: Design Considerations, Teacher Enactment, and Student Learning (United States)

    Drewes, A.; Henderson, J.; Mouza, C.


    Climate change is one of the most pressing challenges facing society, and climate change educational models are emerging in response. This study investigates the implementation and enactment of a climate change professional development model for science educators and its impact on student learning. Using an intrinsic case study methodology, we focused analytic attention on how one teacher made specific curricular, pedagogical, and content decisions, and the implications of those decisions for student's conceptual learning.The research presented here reports on the instructional design, pedagogical enactment, and subsequent effects on student learning of a climate change professional development (PD) model in the United States. Using anthropological theories of conceptual travel, we traced salient ideas from the PD through instructional delivery and into the evidence of student reasoning. We sought to address the following research questions: 1) How did a middle school teacher integrate climate change concepts into her science curriculum following PD participation? and 2) How did climate change instruction influence student understanding of key climate change constructs?From observation of the classroom instruction, we determined that the teacher effectively integrated new climate change information into her pre-existing schema. Additionally, through retrospective analysis of the PD, we found the design of the PD foregrounded the causes, mechanisms and likely effects of anthropogenic climate change at the expense of mitigation and adaptation strategies, and this differentially shaped how climate change was taught in the teacher's classroom. Analysis of student reasoning evidence showed that students gained an increased understanding of the enhanced greenhouse effect and the implications of human activity on this enhanced effect at statistically significant levels and with moderate effect sizes. However, students demonstrated a limited, though non-significant gain on

  11. Western Australian High School Students' Understandings about the Socioscientific Issue of Climate Change (United States)

    Dawson, Vaille


    Climate change is one of the most significant science issues facing humanity; yet, teaching students about climate change is challenging: not only is it multidisciplinary, but also it is contentious and debated in political, social and media forums. Students need to be equipped with an understanding of climate change science to be able to participate in this discourse. The purpose of this study was to examine Western Australian high school students' understanding of climate change and the greenhouse effect, in order to identify their alternative conceptions about climate change science and provide a baseline for more effective teaching. A questionnaire designed to elicit students' understanding and alternative conceptions was completed by 438 Year 10 students (14-15 years old). A further 20 students were interviewed. Results showed that students know different features of both climate change and the greenhouse effect, however not necessarily all of them and the relationships between. Five categories of alternative conceptions were identified. The categories were (1) the greenhouse effect and the ozone layer; (2) types of greenhouse gases; (3) types of radiation; (4) weather and climate and (5) air pollution. These findings provide science educators a basis upon which to develop strategies and curriculum resources to improve their students' understanding and decision-making skills about the socioscientific issue, climate change.

  13. Towards the innovation for microbiology curriculum change: students' perception. (United States)

    Saha, Rumpa; Das, Shukla; Kaur, Iqbal R


    For a medical curriculum to be an effective means of learning for today's students, it has to be designed with knowledge of their priorities, needs and abilities. This can be best achieved by inviting students' view-point during curriculum planning. The present study thus elicits opinion of the medical students through a randomly issued set of questionnaires, towards the present microbiology curriculum in order to quantitate from their view-point, the weakness as well as the strengths of the existing curriculum. Their evaluation reveals that they welcome new techniques like problem-based learning but at the same time emphasise the need to integrate what is taught in close association with clinical circumstance. Hence it is important to understand the minds and needs of our students before implementing the syllabus content across to the consumers.

  15. How to change students' images of science and technology (United States)

    Scherz, Zahava; Oren, Miri


    This paper examines the images middle school students have of science and technology, the workplaces, and the relevant professions. It also describes the effect on these images caused by an instructional initiative, Investigation into Science and Technology (IST), designed to introduce students to science and technology in the real life. Students' images were delineated via questionnaires, drawing tasks, and interviews before and after their participation in the IST program. The sample consisted of 100 students from six classes (eighth or ninth grade) of three schools. We found that before the IST intervention students' images about the scientific or technological environments were superficial, unreal, and even incorrect. Their impressions of the characteristics of scientists and technologists were superficial, misleading, and sometimes reflected ignorance. The findings demonstrate that the IST program stimulated a positive effect on students' images. Their preconceptions were altered in several dimensions: in the cognitive dimension, from superficial and vague to precise and correct images; in the perceptive dimension, from stereotypic to rational and open-minded images; and in the affective dimension, from negative to positive attitudes.

  16. [Eating habits and attitudes towards change in Spanish university students and workers]. (United States)

    Zazpe, Itziar; Marqués, María; Sánchez-Tainta, Ana; Rodríguez-Mourille, Ana; Beunza, Juan-José; Santiago, Susana; Fernández-Montero, Alejandro


    Universities and workplaces are important targets for the promotion of the nutritional interventions in adult population. The aim of this study was to assess the dietary habits and attitudes towards change in workers and university students from different academic fields. The study data came from a cross-sectional study of a Spanish University population of 1,429 participants. We analyzed the dietary habits and the attitudes toward dietary change. The mean age of workers and students was 37 and 23 years, respectively. Both groups reported eating four meals per day. Among students, the consumption of vegetables, wine, fish and nuts was less frequent whereas carbonated beverages, commercial bakery, fast food and red meat was higher. On the other hand, overall dietary pattern of science students was healthier than other students. Although no significant differences were found between students and workers in attitudes towards change, 32% of employees and 39% of students said they were seriously considering changing them. The dietary pattern was healthier among workers than among students, particularly those participants that studied social sciences degrees. They constituted the most vulnerable segment of the university population from a nutritional point of view. About a third of workers and students considered changing their habits.

  17. Sifting through course evaluations: medical student comments driving surgery curriculum changes. (United States)

    French, Judith C; Bickett, Melissa M; Iocono, Joseph A


    Student empowerment of curriculum changes is a double-edged sword. When examining our third-year surgery course every year, we debate where the line is between improving education through student input against allowing the students to design "an easy course." Written student comments on end-of-course evaluations (from the academic years 2006-2007 to 2010-2011) were analyzed using the qualitative approach described by Miles and Huberman. We compared the grouped comments to the course changes that were made over these years to determine what extent were we listening to students. Finally, we took the course changes made and juxtaposed them with student grades and with student course perceptions provided by the end-of-course evaluation analysis. We identified 17 alterations to our curriculum since the year 2007-2008 and of those, 12 are directly related to student comments. Some examples of our changes were a grading-scale alteration, grouping of workshops, and adding a shelf examination review session. The overall course ratings by the students steadily rose over the 5-year period (2.57 to 3.39), while the percentages of A's earned by students decreased over that same time until the year 2010-2011 when the percent of A's earned increased by over 30%. Because of the fact that 12 of 17 course changes can be directly related back to the student comments, we feel confident that we are listening to students. The increase in perception of the course through the first 4 years did not coincide with higher grades. The changes made have been instrumental in the course winning the best clerkship award for the last 4 years. Copyright © 2013 Association of Program Directors in Surgery. Published by Elsevier Inc.

  18. Relative contribution of decreased productivity and survival to recent changes in the demographic trend of the Rivière George Caribou Herd

    Directory of Open Access Journals (Sweden)

    M. Crête


    Full Text Available The Rivière George caribou herd (RGCH was numerically low during the middle part of the century but apparently erupted in the sixties and the seventies. Puberty was early and pregnancy rate was high among RGCH females from 1973 until the mid-eighties when fecundity decreased significantly, in particular among sub-adults; productivity remained low in 1992. Autumn calf:female ratios reflected this trend in pregnancy, exceeding 50 calves: 100 cows between 1973 and 1983, but dropping thereafter progressively to a low of 24 in 1992. In 1993, this ratio rebounded back to 42. Annual adult survival rate of radio-collared females was high (0.95 at the beginning of the monitoring in 1984, but exhibited a variable but declining trend until 1992. Simulations were conducted to estimate the demographic trend of the RGCH between 1984 and 1992, using annual survival rates of radio-collared animals and annual autumn calffemale ratios to estimate calf production. Age structure played a minor role in estimating the finite rate of increase (Lamda. According to the simulations, the RGCH increased in size until 1987, and showed a slight decrease thereafter. The herd should have decreased by 12-15% between 1988 and 1993, according to the simulations. Productivity first caused a decline in Lamda, but in recent years decreased survival contributed slightly more than productivity to the reduction in Lamda. Estimation of the herd size by means of aerial censuses in 1976, 1984, 1988 and 1993 suggested a similar pattern in demographic trend, differences being statistically meaningless. We speculated on the future of the RGCH, that could have erupted after many decades of unfavourable weather. The herd will exhibit a rapid descent to low numbers if wolves show a numerical response to current caribou abundance, or if lichen availability on the winter range decreases due to competition with the adjacent and increasing Rivière aux Feuilles herd; otherwise it will exhibit

  19. The effect of a change in selection procedures on students' motivation to study dentistry. (United States)

    Gardner, S P; Roberts-Thomson, K F


    The aim of this study was to determine whether changes in student selection criteria at The University of Adelaide effected a change in motivation and influencing factors to study dentistry by comparing cohorts. Online questionnaire completed by first-year dentistry students at The University of Adelaide between 1993-1996 and 1997-2005. All 666 students completed the questionnaire with 647 suitable for analysis. The likelihood of students being motivated for a career in dentistry because it 'fits with family' was greater for the 1997-2005 cohort (OR = 1.68, 95% CI = 1.14-2.49, p dentistry. © 2014 Australian Dental Association.

  1. [Recent demographic trends in Turkey]. (United States)

    Behar, C


    Coverage of Turkey's vital registration system remains incomplete, and it cannot yet be used to measure annual population changes. Data and demographic indices based on the 1990 census and the 1989 National Demographic Survey are the most recent available. Turkey's population in 1990 was 56 million. The proportion urban increased to 59% from 49.2% in 1980. Nearly 35% of the population was under 15 years old, and the median age was 21.6 for males and 22.3 for females. The average age at first marriage in 1989 was 24.8 for men and 21.8 for women. Mortality has been in continuous decline. The crude death rate dropped from 16.4/1000 in 1960-65 to slightly under 8 in 1989. Life expectancy at birth was 63.3 for men and 66 for women. The infant mortality rate declined from 166 in 1965-70 to 85 in 1989. Rural or urban residence and maternal educational level were the most significant determinants of infant mortality differentials. Turkey's total fertility rate declined from 6.2 in 1960 to 4.3 in 1978 and 3.4 in 1988-89. The crude birth rate declined from around 40/1000 in 1968 to under 28/1000 in 1989. Fertility began to decline in the last third of the nineteenth century in Istanbul and other large cities of the Ottoman Empire. Istanbul's total fertility rate was a relatively low 3.9 even before World War I. Turkey adopted a policy to slow demographic growth in the mid 1960s, and family planning activities were supported by nongovernmental organizations. The direct impact of these policies on demographic behavior appears to have been somewhat limited, and the use of traditional methods of birth limitation remains widespread. Abortion was legalized in 1983 and is available at public hospitals. The proportion of married women aged 15-49 who use contraception increased from 38% in 1973 to 63% in 1988. Regional differentials in demographic indices are significant in Turkey, with the Anatolian East and Southeast lagging behind other regions in fertility and mortality decline

  2. Long-term impact of changing childhood malnutrition on rotavirus diarrhoea: Two decades of adjusted association with climate and socio-demographic factors from urban Bangladesh. (United States)

    There is strong association between childhood rotavirus, diarrhoea, climate factors and malnutrition. Conversely, a significant nutritional transition (reduced under-nutrition) with a concurrent increasing trend of rotavirus infection in last decade was also observed among under 5 children, especially in developing countries including Bangladesh. Considering the pathophysiology of rotavirus, there might be an interaction of this nutrition transition which plays a pivotal role in increasing rotavirus infection in addition to climate and other man-made factors in urban areas such as Dhaka, Bangladesh. Relevant monthly data from 1993-2012 were extracted from the archive of the Diarrhoeal Disease Surveillance System of icddr, b and linked with data collected from the Dhaka station of the Bangladesh Meteorological Department (mean temperature, rainfall, sea level pressure and humidity). Seasonal autoregressive integrated moving average time series models were deployed to determine the association between the monthly proportion of rotavirus infection and underweight, stunting and wasting adjusting for climate, socio-demographic and sanitation factors. The proportion of rotavirus cases among all causes diarrhoea increased from 20% in 1993 to 43% in 2012 (Chi squared for trend p = 0.010). In contrast, underweight, stunting and wasting decreased from 59%-29% (pchildhood malnutrition is significantly associated with increasing rotavirus diarrhoea among under-5 children. Thus mass vaccination in addition to interventions directed at man-made modifiable predictors for prevention and control is warranted.

  6. The importance of further education. In times of demographical change using the example of energy industry; Die Bedeutung der Weiterbildung in Zeiten des demografischen Wandels am Beispiel der Energiewirtschaft

    Energy Technology Data Exchange (ETDEWEB)

    Schmitz, Marcus [IGS Organisationsberatung GmbH, Koeln (Germany)


    The demographical development in Germany has an impact on the economy. Especially the qualified manpower supply will change not only in our country, but also in all other Western industrial nations. Companies would be well advised, if they previously anticipated the consequences they will face, to check and adjust their human resource strategies, if necessary. The target is to have specialists and executive staff available, according to quantitative as well as qualitative needs. Further education plays a decisive role to meet a shortage of human resources.

  16. The forest and the trees: Industrialization, demographic change, and the ongoing gender revolution in Sweden and the United States, 1870-2010

    Directory of Open Access Journals (Sweden)

    Maria Stanfors


    Full Text Available Background: The separate spheres, in which men dominate the public sphere of politics, arts, media, and wage work and women dominate the private sphere of unpaid production and caring, is a powerful configuration in much social theory (including Parsons, Becker, and Goode, which posited that with industrialization, family structures and activities would converge towards the nuclear family with strict gender roles. Objective: This paper examines the major trends unraveling the gender division of family support and care that reached its peak in the mid-20th century, often called the 'worker-carer' or the 'separate spheres' model, by comparing the experiences of Sweden and the United States. Methods: We use data that includes time series of macro-level demographic and economic indicators, together with cross-sectional data from censuses and time use surveys. Results: The unraveling of the separate spheres began with the increase in the labor force participation of married women and continues with the increase in men's involvement with their homes and children, but its foundations were laid in the 19th century, with industrialization. We show that despite short-term stalls, slowdowns, and even reverses, as well as huge differences in policy contexts, the overall picture of increasing gender sharing in family support and care is strongly taking shape in both countries. Contribution: By doing a comparative, in-depth analysis, it becomes clear that the extreme role specialization within the couple that divided caring from 'work,' though theoretically important, applied only for a limited period in Northern Europe and the United States, however important it might be in other regions.

  18. Thinking style changes among deaf, hard-of-hearing, and hearing students. (United States)

    Cheng, Sanyin; Zhang, Li-fang


    This study explores how university students' thinking styles changed over a single academic year by twice administering the Thinking Styles Inventory-Revised II to 256 deaf or hard-of-hearing (DHH) students and 286 hearing students from art and design academic disciplines in China. Results showed that after having studied at the university for one academic year, hearing students showed increased use of Type I thinking styles (more creativity generated, less structured, and more complex) and less use of Type II thinking styles (more norm favoring, more structured, and more simplistic), whereas DHH students demonstrated increased use of both Type I and Type II thinking styles. Moreover, students' changes in thinking styles differed across university class levels. The contributions, limitations, and implications of the present research are discussed. © The Author 2014.

  20. Economic Effects of Demographic Ageing

    Directory of Open Access Journals (Sweden)

    Litra A.V.


    Full Text Available Romania goes through profound changes due to unprecedented demographic developments. As a result of declining birth rates and emigration after 1990, by the year 2060 is looming a possible doubling of the percentage of the population 65 years and over, from 15 to 30%, and the working age population to fall by about 30 percent. Deterioration of the relationship between labour force and inactive population leads to pressure on the public budget and tax system, strains on pension and social security systems, redefining consumer preferences, type and size of the saved or spent amounts, higher demand for healthcare services, increasing poverty risk for elderly households.
