  1. [Integration of demographic variables into development plans in the Sahel].

    A founding principle of the Program of Action of N'Djamena is the interdependence of population and development and the need for development strategies to take demographic factors into account. The concept of integration of population variables into development has evolved since its introduction in the 1974 World Population Plan of Action from a simple description of population size, growth rates, and distribution to a stress on harmonizing population policies and development policies with macroeconomic variables. The essence of the concept is the consideration given by development policies and programs to the interrelations between population, resources, the environment, and development factors. Population variables and goals should ideally be treated as endogenous variables in development planning, but in practice the extreme complexity of such a systematic approach limits its ability to be made operational. Usually the most crucial problems only are included. Integrated planning is composed of explicit or implicit population policies intended to influence demographic variables and of socioeconomic policies intended to adapt to demographic change. In the Sahel, only Senegal, Burkina Faso, and Mali have formal population policies, but around 1980 several countries of the region began to show interest in influencing demographic variables as they did economic variables. Fundamental principles for developing an integration strategy can be applied regardless or whether the plan is based on projections, analysis of interaction of a demographic variable with factors specific to a sector, or a monosectorial or multisectorial demoeconomic planning model. Demographic data is used more frequently in diagnosing problems than in developing projections or formulating objectives. The level of disaggregation of demographic projections and estimates tends to be low, despite the great potential utility of demographic projections in planning. Demographic projections can be useful

    To change unsafe behavior through adjusting people’s safety attitudes has become an important measure to prevent accidents. Demographic variables, as influential factors of safety attitude, are fundamental and essential for the research. This research does a questionnaire survey among coal mine industry workers, and makes variance analysis and correlation analysis of the results in light of age, length of working years, educational level and experiences of accidents. The results show that the coal miners’ age, length of working years and accident experiences correlate lowly with safety attitudes, and those older coal miners with longer working years have better safety attitude, as coal miners without experiences of accident do.However, educational level has nothing to do with the safety attitude. Therefore, during the process of safety management, coal miners with different demographic characteristics should be put more attention to.

    Genetic analyses of contemporary populations can be used to estimate the demographic histories of species within an ecological community. Comparison of these demographic histories can shed light on community responses to past climatic events. However, species experience different rates of molecular evolution, and this presents a major obstacle to comparative demographic analyses. We address this problem by using a Bayesian relaxed-clock method to estimate the relative evolutionary rates of 22 small mammal taxa distributed across northwestern North America. We found that estimates of the relative molecular substitution rate for each taxon were consistent across the range of sampling schemes that we compared. Using three different reference rates, we rescaled the relative rates so that they could be used to estimate absolute evolutionary timescales. Accounting for rate variation among taxa led to temporal shifts in our skyline-plot estimates of demographic history, highlighting both uniform and idiosyncratic evolutionary responses to directional climate trends for distinct ecological subsets of the small mammal community. Our approach can be used in evolutionary analyses of populations from multiple species, including comparative demographic studies.

    Full Text Available Broad ad targeting options belong among the major advantages of internet advertising. Demographic targeting has become a standard option in most of on-line advertising systems. There are more ways how to target on-line advertisements by using demographic variables. In some cases, e.g., social media, we can use data from user registrations. Modern technologies enable to estimate the demographic profile of internet users using on behavioural data. The traditional approach to the demographic targeting of advertisements based on affinity targeting assumes the existence of internet servers with sufficient homogeneity of visits. The aim of this article is to identify the differences in the internet content consumption habits of Czech internet users based on gender and age. The analysis is based on the data from the extensive research which was carried out by the Netmonitor project, and which was provided for the purposes of this study by the Association for Internet Development (SPIR. The research results show that the traditional affinity-based method of targeting according to gender and age is still suitable on the Czech internet. On the other hand, in some cases, the traditional approach of ad targeting based on affinity leads to wasted ad impressions that miss defined target group.

  11. Environmental versus demographic variability in stochastic predator-prey models

    In contrast to the neutral population cycles of the deterministic mean-field Lotka-Volterra rate equations, including spatial structure and stochastic noise in models for predator-prey interactions yields complex spatio-temporal structures associated with long-lived erratic population oscillations. Environmental variability in the form of quenched spatial randomness in the predation rates results in more localized activity patches. Our previous study showed that population fluctuations in rare favorable regions in turn cause a remarkable increase in the asymptotic densities of both predators and prey. Very intriguing features are found when variable interaction rates are affixed to individual particles rather than lattice sites. Stochastic dynamics with demographic variability in conjunction with inheritable predation efficiencies generate non-trivial time evolution for the predation rate distributions, yet with overall essentially neutral optimization.

    1980-01-01

    The attempt is made in this discussion to describe and draw lessons from the treatment of behavioral demographic variables in the Bachue demo-economic models constructed for the Philippines, Kenya, Brazil and Yugoslavia. Focus is on certain theoretical, technical and practical problems encountered in inserting demographic variables in the system as a whole; how they have been measured in the various applications of the Bachue models, how they are behaviorally explained and linked to the other elements in the system, the data sources used, and some issues of econometric estimates and modelling. 8 issues are dealt with: population accounting and lag structure; fertility; mortality; migration; nuptiality; household formation; schooling; and labor force participation. In each case model structure, dependent and explanatory variables, and empirical strategy are discussed. Summary tables compare the approaches of the different models. The specifics of each country situation rule out the identification of the best solution. Some suggestions regarding more promising approaches are included with respect to choice of variables and the estimation of behavioral models. The endogenous nature of certain demographic elements of a demo-economic model are clear, but construction of the Bachue models has shown that there are no exact rules valid for all cases. There is considerable variety in the way characteristics of the population have been represented in the various applications.

    We examined the contribution of demographics and cognitive background variables (processing speed, visuospatial skill, working memory, and interference control) on derived Trail Making Test (TMT) scores in a large sample of Greek healthy participants. We included 775 participants and administered the TMT (TMT-A and TMT-B) and the Wechsler Intelligence Adult Scale (WAIS). Direct (TMT-A & TMT-B time-to-completion) and derived [difference TMT-(B - A) & ratio TMT-(B/A)] scores were calculated. Demographics (age, age(2), education, and gender) and WAIS Full Intelligence Quotient significantly predicted the direct TMT-A (R(2) = 0.426) and TMT-B (R(2) = 0.593) scores and to a lesser extent, the derived TMT-(B - A) (R(2) = 0.343) and TMT-(B/A) (R(2) = 0.088) scores. In a subsample of 537 healthy participants who also completed the Stroop Neuropsychological Screening Test (SNST), demographics (age and education), WAIS Digit Symbol, Block Design, Arithmetic, and SNST accounted for 44.8% and 59.7% of the variance on TMT-A and TMT-B, and 32.5% and 9.6% of the variance on TMT-(B - A) and TMT-(B/A), respectively. We found minimal influence of Block Design and Arithmetic on TMT-(B - A) and an absence of significant influence of any cognitive variable on TMT-(B/A) score. Concluding, derived TMT scores are suggested as indices to detect impairment in cognitive flexibility across the adult life span, since they minimize the effect of demographics and other cognitive background variables.

    Development of nurse-patient empathic communication in the oncology ward is of great importance for the patients to relieve their psychological stress, however, nursing care of cancer patients is accompanied with high stress and burnout. The present study aimed to define the level of empathy and its association with burnout and some demographic characteristics of oncology nurses. This descriptive/correlation study was conducted in a professional cancer treatment center in Isfahan. Through census sampling, 67 oncology nurses were selected. The data collection tools were Jefferson Scale of Nursing Empathy, Maslach Burnout Inventory, and demographic characteristics questionnaire. Mean nurses' empathy and overall burnout scores were 62.28 out of 100 and 38.8 out of 100, respectively. Score of empathy showed an inverse correlation with overall burnout score (r = -0.189, P = 0.04), depersonalization (r = -0.218, P = 0.02), and personal accomplishment (r = -0.265, P = 0.01). Multiple regression test was used to detect which dimension of burnout was a better predictor for the reduction of empathy score. Results showed that the best predictors were lack of personal accomplishment (P = 0.02), depersonalization (P = 0.04), and emotional exhaustion (P = 0.14), respectively. The most influential demographic factor on empathy was work experience (r = 0.304, P = 0.004). One-way analysis of variance showed that official staff had a higher empathy score (f = 2.39, P = 0.045) and their burnout was lower (f = 2.56, P = 0.04). Results showed a negative relationship between empathy and burnout in oncology nurses. Therefore, nursing support from managers to reduce burnout increases empathic behavior of nurses.

    Full Text Available This paper examines the relationship between socio-economic backgrounds of insurance salesmen on the job performance. The demographic factors studied include age, marital status, educational qualification, job tenure and gender. Using a descriptive design, a total of one hundred and thirteen respondents were studied. Using primary data generated through 1questionnaire, the result of the study analyzed by both regression and correlation indicated a moderate positive relationship between the variable studied and job performance. Jointly, they account for 13% of factors explaining the performance of job of the respondents. However marital status and job tenure were found to be mostly predictive of job performance of insurance salesmen. The paper discussed the implications for the practice of management and human resource management.

    Inflammation may play a role in the accelerated physical aging reported in schizophrenia, though biomarker findings and associations with demographic and clinical factors are inconsistent. In a cross-sectional, case-control design, 95 outpatients with schizophrenia (mean age ± SD: 48.1 ± 10.2 years) and 95 demographically comparable healthy comparison subjects (HCs) (mean age ± SD: 48.1 ± 12.1 years) were studied. Sociodemographic and clinical data were collected, and plasma levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and interferon-γ (IFN-γ) were assayed. The authors compared cytokine levels, examined demographic and clinical associations, and adjusted for relevant variables with linear models. Individuals with schizophrenia had higher levels of TNF-α and IL-6 but not IFN-γ than HCs. Age was not related to cytokine levels, and age relationships did not differ between diagnostic groups. Women had higher levels of IL-6. TNF-α and IL-6 levels were significantly correlated with depressive symptoms, and adjustment for depression reduced the group effect for both. Within the HCs, TNF-α levels were associated with physical comorbidity and body mass index. IL-6 levels were significantly correlated with body mass index and within schizophrenia patients, with worse mental and physical well-being. Accounting for physical morbidity and mental well-being reduced group differences in TNF-α and IL-6 levels, respectively. Worse positive symptoms were associated with higher IL-6 levels. Higher TNF-α and IL-6 levels in schizophrenia patients were associated with depression, physical comorbidity, and mental well-being. Further longitudinal studies are warranted to assess inflammation as a potential treatment target for a subgroup of schizophrenia. Copyright © 2017 American Association for Geriatric Psychiatry.

    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

    Full Text Available Abstract Background Depression and anxiety are common psychiatric symptoms in patients with epilepsy, exerting a profound negative effect on health-related quality of life. Several issues, however, pertaining to their association with psychosocial, seizure-related and medication factors, remain controversial. Accordingly, the present study was designed to investigate the association of interictal mood disorders with various demographic and seizure-related variables in patients with newly-diagnosed and chronic epilepsy. Methods We investigated 201 patients with epilepsy (51.2% males, mean age 33.2 ± 10.0 years, range 16–60 with a mean disease duration of 13.9 ± 9.5 years. Depression and anxiety were assessed in the interictal state with the Beck Depression Inventory, 21-item version (BDI-21 and the state and trait subscales of the State-Trait Anxiety Inventory (STAI-S and STAI-T, respectively. The association of mood disorders with various variables was investigated with simple and multiple linear regression analyses. Results High seizure frequency and symptomatic focal epilepsy (SFE were independent determinants of depression, together accounting for 12.4% of the variation of the BDI-21. The STAI-S index was significantly associated with the type of epilepsy syndrome (SFE. Finally, high seizure frequency, SFE and female gender were independent determinants of trait anxiety accounting for 14.7% of the variation of the STAI-T. Conclusion Our results confirm the prevailing view that depression and anxiety are common psychological disorders in epileptics. It is additionally concluded that female gender, high seizure frequency and a symptomatic epilepsy syndrome are independent risk factors for the development of anxiety and/or depression.

    Full Text Available The purpose of this study was to investigate the relationships between knowledge sharing behaviour and the demographic variables gender, age, organisational tenure and professional tenure. Following a correlational survey approach, the study sourced its data from senior secondary school teachers in and around Gaborone, Botswana. Knowledge sharing behaviour was measured using an instrument sourced from the extant literature. No statistically significant relationship was detected between knowledge sharing behaviour and gender, age, or professional tenure. Only organisational tenure weakly negatively correlated with knowledge sharing behaviour. Thus, according to these findings, demographic variables do not appear to be important determinants of knowledge sharing behaviour.

    Full Text Available Many studies have already been conducted to understand the various dimensions of the burnout. The purpose of the present research is to investigate the moderating effect of demographic variables on the relationship between job burnout and its consequences among the staff of an Iranian public sector company. In this research, job burnout is considered as independent variable; organizational commitment, intention to leave and the employees‟ job satisfaction are dependent variables; and the age, gender, marital status and educational level are moderating variables. The results of this study show that firstly, the job burnout of employees in organizations leads to the decrease of organizational commitment and job satisfaction, and the increase of intention to leave; secondly, the demographic variables in this research don't affect on the relationship of job burnout with its consequences.

    Maltreatment of children is a major public-health and social-welfare problem but socio-demographic variability has received little attention. This work addresses such variability in a general population cohort and associations with depression. Analyses were based on the cross-sectional SHIP-LEGEND examination among 2265 adults (29-89 years). Childhood maltreatment was multi-dimensionally assessed with the German 28-item Childhood Trauma Questionnaire (CTQ): emotional neglect; emotional abuse; physical neglect; physical abuse; sexual abuse. Non-linear associations between CTQ responses and age were assessed with fractional polynomials and cubic splines. Scale properties were analysed with confirmatory factor analyses and item response models. Associations between childhood maltreatment domains and depression [Beck Depression Inventory-II (BDI-II)] were assessed. The majority (58.9%) reported events indicative of at least mild levels of childhood maltreatment. CTQ subscales showed characteristically different non-linear associations to age across the five studied domains, indicating methodological issues like recall bias and the influence of seminal events. Psychometric scale properties were acceptable to good for all subscales except for physical neglect. Associations to depression measures varied systematically across socio-demographic strata. We conclude that socio-demographic variability is a major issue when studying self-reported childhood maltreatment in a community sample. This needs to be taken into account for the study of associations to psychiatric key outcomes. Copyright © 2014 John Wiley & Sons, Ltd.

    This study aims to assess the prevalence of different modes of commuting to school and work for 10-12year-olds and their parents; to assess the associations with demographic variables (country, sex, parental education and ethnicity) and with weight status in eight European countries. As part of the ENERGY project a cross-sectional survey was conducted in 2010 in which modes of commuting and socio-demographic variables for children (N=7903) and one of their parents (n=6455) were measured by questionnaires. Children's weight and height were objectively measured; parents self-reported their weight and height. Logistic multilevel regression analyses assessed the associations between mode of commuting and overweight. Differences between countries and differences in mode of commuting according to demographic variables were tested using χ(2)-test and Marascuilo's Post-hoc analysis. There were marked differences between countries, especially regarding cycling to school, which was common in The Netherlands and Norway and rare in Greece and Spain. Demographic variables were associated with mode of commuting in children and parents. Mode of commuting was not associated with being overweight in children, after adjustment for demographic variables. Bicycling to work, but not other modes of commuting, was significantly inversely associated with being overweight among parents (OR=0.74 (95%CI 0.57-0.97)). Interventions targeting active commuting may promote cycling, and should take into account the differences regarding demographic variables. Copyright © 2017 Elsevier Inc. All rights reserved.

    The aim of the current study was to examine the relationships among demographic characteristics, psychosocial variables, symptom severity, and quality of life (QOL), and the way these variables affect QOL in patients with schizophrenia living in Hubei, China. A convenience sample of 178 individuals with schizophrenia participated. The results suggest that the Schizophrenia Quality of Life Scale was positively and statistically significantly correlated with employment status (r = 0.232, p empowerment (r = 0.692; p empowerment (accounting for 22.1% of variance) was the best positive predictor, whereas symptom severity (accounting for 7.6% of variance) was the best negative predictor of QOL in patients with schizophrenia. Implications for future research and practice are discussed. [Journal of Psychosocial Nursing and Mental Health Services, 55(8), 48-54.]. Copyright 2017, SLACK Incorporated.

    Background: The literature is replete with reports that pregnant women have an increased level of periodontal disease as compared with non-pregnant women of the same age. There are many studies correlating the effect of periodontal disease on the adverse pregnancy outcomes. The development of periodontal diseases during pregnancy can be influenced by factors such as preexisting oral conditions, general health, and socio-cultural background. There is very little data studying the effect of socio-demographic factors on the periodontal health of pregnant women. This study evaluated the periodontal status of a sample of pregnant women of Chandigarh and adjoining areas. The study also investigated the relationship between these variables and a series of demographic and clinical variables. Materials and Methods: The participants were 190 pregnant women attending Gynecology and Obstetrics outpatient department of Government Medical College and Hospital, Chandigarh. The participants were examined for their periodontal health and various socio-demographic variables were recorded on performas designed for the purpose of study. Statistical analysis was done. Results: The results revealed that the mean bleeding index scores and probing depth increased with statistical significance when the socio-economic status was lower (P0.1). The plaque index was not significantly associated with the socio-economic status, profession, place of residence, and trimester of pregnancy (P>0.1). Conclusion: In the population of pregnant women investigated under this study, the clinical and socio-demographic characteristics showed non-significant correlation except socio-economic status which showed statistically significant correlation with bleeding on probing and pocket depth. Further studies may be required in Indian population to determine the association of periodontal diseases in pregnant women with socio-demographic variables. PMID:23633773

    Tinnitus is a highly prevalent symptom with potential severe morbidity. Fortunately, only a small proportion of the population experience problems due to their tinnitus in such a degree that it adversely affects their quality of life (clinically significant tinnitus). It is not known why these individuals develop more burden from tinnitus. It seems likely that the severity of tinnitus can be influenced by different factors, such as socio-demographic or tinnitus characteristics or additional health complaints. It remains unclear from the current literature as to what are the main independent variables that have a bearing on tinnitus severity. This study addresses this problem by investigating variables previously described in the literature as well as additional variables. The aim of this study is to identify socio-demographic, health, and tinnitus variables that independently relate to tinnitus severity the most. This is a retrospective cohort study performed at the Tinnitus Care Group of the University Medical Center, Utrecht, in 309 consecutively seen chronic tinnitus patients. At this care group, patients are examined according to a structured diagnostic protocol, including history-taking by an otorhinolaryngologist and audiologist, physical examination, and audiometry. Based on results from previous research and theoretical considerations, a subset of data acquired through this diagnostic protocol were selected and used in this study. Univariate and multivariate correlations with tinnitus severity were investigated for 28 socio-demographic, health, and tinnitus variables. Tinnitus severity was measured with the Tinnitus Questionnaire (TQ) and the Tinnitus Handicap Inventory (THI). Eighteen variables related univariately with the TQ and 16 variables related univariately with the THI. Among these, 14 variables related univariately with both the TQ and the THI. Multivariate analyses showed three variables with an independent significant effect on both the TQ and

    In past few decades, emotional intelligence (EI) has gained much popularity worldwide. Intelligence quotient alone is not enough in today's age for achieving success and hence for developing a person's ability, the fields of psychology and neurosciences have highlighted the importance of EI, which is a person's response toward feelings and emotions. In this study, relationship of various demographic variables with EI, as measured by Trait Emotional Intelligence Questionnaire-Short Form, has been highlighted. The study has been conducted on a sample of 424 employees belonging to the Indian service sector. The results showed that demographic variables have an impact over EI. Organizations can take a cue from the study and adhere to diversity management practices to ensure financial gains and growth. PMID:27536018

    Prospective analysis of resource utilization (RU) after lumbar surgery. To determine contributions of patient psychosocial variables to RU, specifically length of stay (LOS) and discharge destination. Associations between demographic/clinical variables and RU are well-established; less is known about associations between psychosocial variables, such as social support and depressive/anxiety symptoms, and RU. Preoperatively 532 patients provided standard ratings of depressive and anxiety symptoms and amount of social support. Clinical variables included calculation of a composite score reflecting invasiveness of surgery. Two outcomes were considered: LOS ≤ 3 or > 3 days; and discharged home without external services or discharged with external services. Independent variables in multivariable logistic models were demographic/clinical and psychosocial variables. Mean age was 56 years, 55% were men, 87% had degenerative conditions, 40% had a positive depression screen, 62% had anxiety greater than population norms, and 77% reported as much social support as wanted. Variables that remained associated with a LOS > 3 days (53%) in multivariable analysis were: older age (OR 1.8, CI 1.2-2.8); female gender (OR 1.9, CI 1.2-2.9), less social support (OR1.4, CI 1.1-1.7); obesity (OR1.8, CI 1.1-2.8), worse functional status (OR 1.0, CI 1.0-1.0) and more invasive surgery (OR 3.0, CI 2.4-3.7). Variables that remained associated with discharged with external services (17%) in multivariable analysis were: older age (OR 3.3, CI 1.9-5.9); less social support (OR 1.3, CI 1.0-1.7); positive depression screen (OR 1.9, CI 1.1-3.4); more anxiety (OR 2.4, CI 1.3-4.2); major comorbidity (OR 1.7, CI 1.0-2.8); and more invasive surgery (OR 1.9, CI 1.5-2.5). This study confirms the importance of demographic/clinical variables as predictors of greater RU after lumbar surgery and provides preliminary evidence for the importance of concurrent psychosocial variables, particularly less social

    Full Text Available The aim of this study is to demonstrate the relations and differences between personality traits of teachers and some demographic variables. This research is designed in a descriptive survey model. The study group is composed of 407 teachers who are working in 22 public high schools from Ataşehir, Beşiktaş, Güngören and Ümraniye districts of Istanbul. Big Five Inventory, which is developed by Benet-Martinez and John (1998 and adapted to Turkish by Sümer and Sümer (2005, is used in order to assess the teacher personality traits. The scale of Alpha coefficient is, .699. As a result, teachers the highest average is in openness to experience and the lowest average is in neuroticism. Also it is found that significant differences exist between teachers’ personality traits and demographic variables. In accordance to this, significant differences are observed between gender variable and conscientiousness, extraversion, agreeableness, neuroticism. There are similar differences between marital status variable and openness to experience, conscientiousness, agreeableness. The differences between branch variable and openness to experience, extraversion are also significant.

  1. Beyond R0: demographic models for variability of lifetime reproductive output.

    Directory of Open Access Journals (Sweden)

    Hal Caswell

    Full Text Available The net reproductive rate R0 measures the expected lifetime reproductive output of an individual, and plays an important role in demography, ecology, evolution, and epidemiology. Well-established methods exist to calculate it from age- or stage-classified demographic data. As an expectation, R0 provides no information on variability; empirical measurements of lifetime reproduction universally show high levels of variability, and often positive skewness among individuals. This is often interpreted as evidence of heterogeneity, and thus of an opportunity for natural selection. However, variability provides evidence of heterogeneity only if it exceeds the level of variability to be expected in a cohort of identical individuals all experiencing the same vital rates. Such comparisons require a way to calculate the statistics of lifetime reproduction from demographic data. Here, a new approach is presented, using the theory of Markov chains with rewards, obtaining all the moments of the distribution of lifetime reproduction. The approach applies to age- or stage-classified models, to constant, periodic, or stochastic environments, and to any kind of reproductive schedule. As examples, I analyze data from six empirical studies, of a variety of animal and plant taxa (nematodes, polychaetes, humans, and several species of perennial plants.

The proposed study of this paper considers the effects of personal characteristics such as age, gender and marital status on social media. The study designs a questionnaire and distributes 385 questionnaires among students who are enrolled in different educational levels in governmental university named Allameh Tabatabayi university located in Tehran, Iran during the year of 2011. Because of abnormality of data, non-parametric test were used. In this research, we studied the effects of demographic variables on success of social media. The results showed that success of social media is more important among female students. Marriage situation shows that social media success variable is more important among married than single ones and, finally, this variable is more important among older people.

  3. Environmental vs. demographic variability in stochastic lattice predator-prey models

    Tauber, Uwe C.

    2014-03-01

    In contrast to the neutral population cycles of the deterministic mean-field Lotka-Volterra rate equations, including spatial structure and stochastic noise in models for predator-prey interactions yields complex spatio-temporal structures associated with long-lived erratic population oscillations. Environmental variability in the form of quenched spatial randomness in the predation rates results in more localized activity patches. Population fluctuations in rare favorable regions in turn cause a remarkable increase in the asymptotic densities of both predators and prey. Very intriguing features are found when variable interaction rates are affixed to individual particles rather than lattice sites. Stochastic dynamics with demographic variability in conjunction with inheritable predation efficiencies generate non-trivial time evolution for the predation rate distributions, yet with overall essentially neutral optimization.

  4. Online Unmixing of Multitemporal Hyperspectral Images Accounting for Spectral Variability.

    2016-09-01

    Hyperspectral unmixing is aimed at identifying the reference spectral signatures composing a hyperspectral image and their relative abundance fractions in each pixel. In practice, the identified signatures may vary spectrally from an image to another due to varying acquisition conditions, thus inducing possibly significant estimation errors. Against this background, the hyperspectral unmixing of several images acquired over the same area is of considerable interest. Indeed, such an analysis enables the endmembers of the scene to be tracked and the corresponding endmember variability to be characterized. Sequential endmember estimation from a set of hyperspectral images is expected to provide improved performance when compared with methods analyzing the images independently. However, the significant size of the hyperspectral data precludes the use of batch procedures to jointly estimate the mixture parameters of a sequence of hyperspectral images. Provided that each elementary component is present in at least one image of the sequence, we propose to perform an online hyperspectral unmixing accounting for temporal endmember variability. The online hyperspectral unmixing is formulated as a two-stage stochastic program, which can be solved using a stochastic approximation. The performance of the proposed method is evaluated on synthetic and real data. Finally, a comparison with independent unmixing algorithms illustrates the interest of the proposed strategy.

    Full Text Available Background: Few population-based studies have examined the association between physical activity (PA and cardiovascular disease risk factors, demographic variables, and perceptions of health status, and we do not have a clear understanding of the dose-response relationship among these variables. Methods: Data from the 2003-2006 National Health and Nutrition Examination Survey was used to examine the dose-response relationship between objectively measured PA and metabolic syndrome (and its individual cardiovascular disease risk factors, demographic variables, and perceptions of health. After exclusions, 5,538 participants 18 years or older were included in the present study, with 2,538 participants providing fasting glucose and 2,527 providing fasting triglyceride data. PA was categorized into deciles. Results: Overall, the health benefits showed a general pattern of increase with each increasing levels of PA. Of the ten PA classifications examined, participants in the highest moderate-to-vigorous physical activity (MVPA category (at least 71 min/day had the lowest odds of developing metabolic syndrome. Conclusion: At a minimum, sedentary adults should strive to meet current PA guidelines (i.e., 150 min/week of MVPA, with additional positive benefits associated with engaging in three times this level of PA.

    The existence of important socioeconomic disparities in health and mortality is a well-established fact. Many pathways have been adduced to explain inequality in life spans. In this article we examine one factor that has been somewhat neglected: People with different levels of education get sorted into jobs with different degrees of exposure to workplace attributes that contribute to poor health. We used General Social Survey data to estimate differential exposures to workplace conditions, results from a meta-analysis that estimated the effect of workplace conditions on mortality, and a model that permitted us to estimate the overall effects of workplace practices on health. We conclude that 10-38 percent of the difference in life expectancy across demographic groups can be explained by the different job conditions their members experience.

    Information technology has achieved robust growth which has made it possible for learning to occur quickly. The rapid development of information, communication and technologies (ICT) has initiated an unparalleled transformation in universities all over the world. This development of technology and learning is offering new techniques to represent knowledge, new practices, and new global communities of learners. As a result, today’s economic and social changes force universities to try to find new learning approaches and systems. E-learning seems to be an appropriate approach in this aspect. However, the implementation of e-learning systems in universities is not an easy task because of some challenges related to context, technology, and other challenges. This paper studied the impacts of demographic data and reported the critical points for the decision makers to consider when planning and implementing e-learning in universities. A quantitative approach was used to study the effects of technological and contextual challenges on e-learning implementation in which a questionnaire was used for the data collection. According to the findings of the study, the most important challenges of the implementation of e-learning are related either to organizational (Contextual) and technological (technical) issues. The demographic variables have been found to play a direct and indirect role with the technological and contextual challenges of implementing e-learning. This paper showed that there are some significant differences in the two challenges faced by instructors in terms of the demographic variables. The result revealed that some significant differences exist between demographic variables and the two challenges of e-learning in terms of gender, age, teaching experience, ICT experience and e-learning experience. However, there is no significant difference in terms of e-learning experience. The obtained data, from such study, can provide information about what academic

    Medical education must encourage autonomous learning behaviors among students. However the great income profile disparity among university students may influence their capacity to acquire such skills. To assess the association between self-directed learning, socio-demographic and academic variables. The self-directed learning readiness scale was applied to 202 medical students aged between 17 and 25 years (64% males). Simultaneously information about each surveyed participant was obtained from the databases of the medical school. There is an association between socio-demographic and academic variables with the general scale of self-directed learning and the subscales learning planning and willingness to learn. Participants coming from municipal schools have a greater willingness to learn than their counterparts coming from subsidized and private schools. High school grades are related to self-directed learning and the subscales learning planning and self-assessment. Among the surveyed medical students, there is a relationship between self-directed learning behaviors, the type of school where they come from and the grades that they obtained during high school.

    Full Text Available What seems to still be the main concern for managers and employees in the organization world across the globe is communication effectiveness. The problem to be addressed in this study was the lack of motivation and job satisfaction in educational administrations of Iran. Upon reviewing various literatures on this subject, it was found that emotional intelligence is one of the most vital factors that help sustain communication effectiveness and job satisfaction. The researcher upon having a detailed discussion on the possible areas associated with the present body of knowledge has discovered gaps in the studies that have been undertaken on emotional intelligence and communication effectiveness. This is because motivation in relation to emotional intelligence, communication effectiveness, and job satisfaction has been ignored in the previous studies. As a result, this research proposes a relationshipbetween demographic variables, emotional intelligence (i.e., intrapersonal, interpersonal, adaptability, general mood, and stress management, Communication Effectiveness, Job Satisfaction, and Motivation.

The sample was composed of 161 students, who completed the Honey-Alonso questionnaire (CHAEA and the CDAT. Descriptive and correlational methods were used. For the analysis of the data, a univariate (one-way ANOVA descriptive study was performed, and the non-parametric Mann-Whitney and Kruskal-Wallis tests, both with a confidence level of 95% (σ=.05 were used. The results show the predominance of the reflective style, and the fact that grades as a function of styles vary depending on the school subject. No significant differences were found in the variables gender, university admission scores, type of school (private or public of the study centers attended previous to university. Significant differences were found for some styles in the variables age, type of university admission, and if a student had to work as well as to study. The conclusions highlight the need to develop teaching strategies that encompass all the styles to improve performance, as well as the need to modify the teaching practices for the students to develop the rest of the styles in a balanced manner. This latest aspect is important so that the students can freely operate professionally, as the Engineering profession requires having all four characteristic styles simultaneously.

    Lyme disease is the United States' most significant vector-borne illness. Virginia, on the southern edge of the disease's currently expanding range, has experienced an increase in Lyme disease both spatially and temporally, with steadily increasing rates over the past decade and disease spread from the northern to the southwestern part of the state. This study used a Geographic Information System and a spatial Poisson regression model to examine correlations between demographic and land cover variables, and human Lyme disease from 2006 to 2010 in Virginia. Analysis indicated that herbaceous land cover is positively correlated with Lyme disease incidence rates. Areas with greater interspersion between herbaceous and forested land were also positively correlated with incidence rates. In addition, income and age were positively correlated with incidence rates. Levels of development, interspersion of herbaceous and developed land, and population density were negatively correlated with incidence rates. Abundance of forest fragments less than 2 hectares in area was not significantly correlated. Our results support some findings of previous studies on ecological variables and Lyme disease in endemic areas, but other results have not been found in previous studies, highlighting the potential contribution of new variables as Lyme disease continues to emerge southward.

    Ride-quality experiments similar in objectives, design, and procedure were conducted, one using the U.S. Air Force Total In-Flight Simulator and the other using the Langley Passenger Ride Quality Apparatus to provide the motion environments. Large samples (80 or more per experiment) of test subjects were recruited from the Tidewater Virginia area and asked to rate the comfort (on a 7-point scale) of random aircraft motion typical of that encountered during STOL flights. Test subject characteristics of age, sex, and previous flying history (number of previous airplane flights) were studied in a two by three by three factorial design. Correlations were computed between one dependent measure, the subject's mean comfort rating, and various demographic characteristics, attitudinal variables, and the scores on Spielberger's State-Trait Anxiety Inventory. An effect of sex was found in one of the studies. Males made higher (more uncomfortable) ratings of the ride than females. Age and number of previous flights were not significantly related to comfort ratings. No significant interactions between the variables of age, sex, or previous number of flights were observed.

Given the unique demographic diversity within the South African context, differences in the experience of well-being among women are expected.Purpose: The study investigated the effects of age, race, marital status and educational status on psychological meaningfulness, life satisfaction, work–family conflict and social support of working women.Motivation: With the increase of women in the workplace, there is a need for knowledge and understanding of the factors that influence the well-being of women. This study aims to investigate demographic variables as determinants of well-being among working women.Method: Cross-sectional surveys were used to gather data from a sample (n = 540 of women from various South African companies. The Utrecht Work Engagement Scale (UWES, the Psychological Meaningfulness Scale (PMS, the Satisfaction with Life Scale (SWLS, the WorkRole Conflict Scale and the Job Demands Resources Scale (JDRS were administered.Results: Significant relationships were found between life satisfaction, work-to-family conflict and work engagement, respectively, and marital status. Higher levels of education showed significant relationships with life satisfaction and work-to-family conflict. Being white showed significant positive relationships with life satisfaction, work-to-family conflict and work engagement. With regard to social support and psychological meaningfulness, race explained significant amounts of variance in psychological meaningfulness, as did age.Practical, managerial and methodological implications: The findings indicate that the experiences of well-being among women vary by age, race, marital status and educational status. It is therefore imperative that human resource practitioners appropriately measure these differences, accommodate them in policies through relevant supportive practices and also champion these practices for

    Introduction Although adjustment disorder (AD) is considered as residual diagnosis and receives little attention in research, it plays an important role in clinical practice and also assumes an increasingly important role in the field of legal medicine, where the majority of diagnostic frameworks (eg, mobbing) often refer to AD. Our study aimed to look for specific stressor differences among demographic and clinical variables in a naturalistic setting of patients with AD. Methods A restrospective statistical analysis of the data of patients diagnosed with AD from November 2009 to September 2012, identified via manual search from the archive of the outpatient setting at the University Unit of Psychiatry “A. Fiorini” Hospital, Terracina (Latina, Italy), was performed. Results The sample consisted of 93 patients (46 males and 47 females), aged between 26 and 85, with medium–high educational level who were mainly employed. In most cases (54.80%), a diagnosis of AD with mixed anxiety and depressed mood was made. In all, 72% of the sample reported a negative family history for psychiatric disorders. In 22.60%, a previous history of psychopathology, especially mood disorders (76.19%), was reported. The main stressors linked to the development of AD were represented by working problems (32.30%), family problems (23.70%), and/or somatic disease (22.60%) with significant differences with respect to age and sex. Half of the patients were subjected to a single first examination; 24.47% requested a copy of medical records. Conclusion Confirming previous data from previous reports, our results suggest that AD may have a distinct profile in demographic and clinical terms. Increased scientific attention is hoped, particularly focused on addressing a better definition of diagnostic criteria, whose correctness and accuracy are critical, especially in situations with medicolegal implications.

    Classification and regression tree methods represent a potentially powerful means of identifying patterns in exposure data that may otherwise be overlooked. Here, regression tree models are developed to identify associations between blood concentrations of benzene and lead and over 300 variables of disparate type (numerical and categorical), often with observations that are missing or below the quantitation limit. Benzene and lead are selected from among all the environmental agents measured in the NHEXAS Region V study because they are ubiquitous, and they serve as paradigms for volatile organic compounds (VOCs) and heavy metals, two classes of environmental agents that have very different properties. Two sets of regression models were developed. In the first set, only environmental and dietary measurements were employed as predictor variables, while in the second set these were supplemented with demographic and time-activity data. In both sets of regression models, the predictor variables were regressed on the blood concentrations of the environmental agents. Jack-knife cross-validation was employed to detect overfitting of the models to the data. Blood concentrations of benzene were found to be associated with: (a) indoor air concentrations of benzene; (b) the duration of time spent indoors with someone who was smoking; and (c) the number of cigarettes smoked by the subject. All these associations suggest that tobacco smoke is a major source of exposure to benzene. Blood concentrations of lead were found to be associated with: (a) house dust concentrations of lead; (b) the duration of time spent working in a closed workshop; and (c) the year in which the subject moved into the residence. An unexpected finding was that the regression trees identified time-activity data as better predictors of the blood concentrations than the measurements in environmental and dietary media.

    Sexually transmitted diseases (STDs) have been a subject of discussion both among scientists and in the mass media, especially because of their association with the human immunodeficiency virus (HIV). We studied the adoption of specific protective behaviors for the prevention of STDs among women, as well as the associations between these behaviors and socioeconomic and demographic variables. This was a descriptive study based on secondary data from a previous study carried out in Campinas, São Paulo State, Brazil. A total of 635 women were selected using the social network ("snowball") technique. Subjects were classified into four groups: adolescents and adults of upper middle and lower socioeconomic status, respectively. Condoms were the STD prevention method most frequently mentioned by interviewees. A negative association was observed between having a steady partner and condom use in all the groups. The main reason mentioned for not using condoms was "having a single partner and trusting him". Among adolescents, a positive association was observed between schooling above the 8th grade and condom use, and a negative association was observed between age and condom use. Among adults, only condom use in general was also positively associated with socioeconomic status.

    To investigate whether demographic variables and work-related factors predict work motivation in Greek nurses. Nurses' motivation is crucial for an effective health-care system. Herzberg's and Maslow's motivation theories constitute the framework of this study. The sample consisted of 200 nurses from every sector and registration level in a University Hospital in Greece. The response rate was 76%. A previously developed and validated questionnaire addressing four work-related motivators (job attributes, remuneration, co-workers and achievements) on a five-point Likert scale. Most participants were women, married, between 36 years and 45 years old and higher education graduates. The highest mean score was recorded for 'achievements' (mean 4.07, SD 0.72), which emerged as the most important motivator. Job satisfaction, work sector and age were statistically significantly related to motivational factors. Nurses placed emphasis on motivators not strictly relating to economic rewards, but which can be seen as intrinsic and could lead to self-actualization. The constantly changing health sector requires that human resources and job context be a priority for health administrators. By promoting nurses' satisfaction and efficacy, an improvement in service quality is expected. © 2012 Blackwell Publishing Ltd.

    Full Text Available Abstract Background Pharmacokinetic and pharmacodynamic (PK/PD indices are increasingly being used in the microbiological field to assess the efficacy of a dosing regimen. In contrast to methods using MIC, PK/PD-based methods reflect in vivo conditions and are more predictive of efficacy. Unfortunately, they entail the use of one PK-derived value such as AUC or Cmax and may thus lead to biased efficiency information when the variability is large. The aim of the present work was to evaluate the efficacy of a treatment by adjusting classical breakpoint estimation methods to the situation of variable PK profiles. Methods and results We propose a logical generalisation of the usual AUC methods by introducing the concept of "efficiency" for a PK profile, which involves the efficacy function as a weight. We formulated these methods for both classes of concentration- and time-dependent antibiotics. Using drug models and in silico approaches, we provide a theoretical basis for characterizing the efficiency of a PK profile under in vivo conditions. We also used the particular case of variable drug intake to assess the effect of the variable PK profiles generated and to analyse the implications for breakpoint estimation. Conclusion Compared to traditional methods, our weighted AUC approach gives a more powerful PK/PD link and reveals, through examples, interesting issues about the uniqueness of therapeutic outcome indices and antibiotic resistance problems.

    According to the interim report of Healthy Japan 21, promoting Exercise Guideline 2006 is one important issue in the fields of physical activity and exercise. However, a previous study indicated that Japanese people rarely were aware of Exercise Guideline 2006 (Higo & Nakamura, 2008). The purpose of the present study was to identify characteristics of those who were aware of the guideline. The subjects were 1,613 Japanese adults (40.2 +/- 12.2 years) recruited by a Japanese social research company. The study designwas cross-sectional, using an internet questionnaire. Regarding the research items, the dependent variable was awareness of Exercise Guideline 2006, and the independent variables included awareness of other health promotion policies such as Healthy Japan 21, the Japanese Nutrition Balance Guide, and the Japanese national policy for preventing metabolic syndrome, as well as demographic variables (e.g., gender, age, BMI, hours per day spent watching TV watching and hours per day with internet usage). Logistic regression analysis was used for this research. Of all subjects, 12.3% answered that they were aware of Exercise Guideline 2006. Those over 50 years old (OR = 2.17; 95% CI = 1.11-4.22), having over 10 million household income (OR = 1.94; 99% CI = 1.05-3.61), an exercise habit (OR = 1.75; 95% CI = 1.07-2.86), an awareness of Healthy Japan 21 (OR = 23.60; 95% CI = 15.26-36.52), the Japanese Nutrition Balance Guide (OR = 5.52; 95% GCI = 3.01-10.13), and the Japanese national policy for preventing metabolic syndrome (OR = 3.41; 95% CI = 2.12-5.48) were significantly more likely to be aware of the guideline. Major findings of this study were: 1) older people are more aware of Exercise Guideline 2006 than their younger counterparts, although level of awareness was generally low; 2) for promotion of Exercise Guideline 2006, targeting those with a low educational background might not be a critical issue; and 3) awareness levels for Exercise Guideline 2006 and

    Demographic rates are shaped by the interaction of past and current environments that individuals in a population experience. Past environments shape individual states via selection and plasticity, and fitness-related traits (e.g. individual size) are commonly used in demographic analyses to represent the effect of past environments on demographic rates. We quantified how well the size of individuals captures the effects of a population's past and current environments on demographic rates in a well-studied experimental system of soil mites. We decomposed these interrelated sources of variation with a novel method of multiple regression that is useful for understanding nonlinear relationships between responses and multicollinear explanatory variables. We graphically present the results using area-proportional Venn diagrams. Our novel method was developed by combining existing methods and expanding upon them. We showed that the strength of size as a proxy for the past environment varied widely among vital rates. For instance, in this organism with an income breeding life history, the environment had more effect on reproduction than individual size, but with substantial overlap indicating that size encompassed some of the effects of the past environment on fecundity. This demonstrates that the strength of size as a proxy for the past environment can vary widely among life-history processes within a species, and this variation should be taken into consideration in trait-based demographic or individual-based approaches that focus on phenotypic traits as state variables. Furthermore, the strength of a proxy will depend on what state variable(s) and what demographic rate is being examined; that is, different measures of body size (e.g. length, volume, mass, fat stores) will be better or worse proxies for various life-history processes.

    Full Text Available Most of the disabled people are faced with many physical, social and cultural problems. Social barriers deprive them from using civil and welfare utilities and social vulgar and inexpert attitudes toward the disabled keep them out from the social life and relations. Using ICT is one of the best ways for their participation in all cultural, social, political and economic issues. In recent years, with the emergence of the concept of telework, entrepreneurial process has also changed. As many jobs require attendance at a particular place or time, they are associated with restrictions. Entrepreneurship and consequently telework can provide an appropriate opportunity for disabled or those who temporarily suffer from physical injuries. This is possible only by using information technology services; because in the present age information technology has undertaken a leadership role and has overshadowed different dimensions of human life. Planning and especial policies for the disabled would be unsuccessful or very expensive without the knowledge and understanding of their needs. Therefore, aim of this research is studying Effect of Demographic Variables and Utilization of ICT in Employment of Disabled. Furthermore with regard to the type of disability and employment, using ICT and findings of this research, scientific planning can proceed in this area based on existing capabilities. The results of this study show that half of the sample case is unemployed. However, the percentage of unemployed deaf was lower than other groups. Despite laws for the employment of disabled, as the results show, a lot of people with disabilities are still unemployed. Furthermore, the results define the more need of deployment of strategies and programs for more access of disabled to ICT and also providing a good platform to familiarize them to this technology and to enjoy the benefits of it.

  15. Online unmixing of multitemporal hyperspectral images accounting for spectral variability

    CERN Document Server

    Thouvenin, Pierre-Antoine; Tourneret, Jean-Yves

    2015-01-01

    Hyperspectral unmixing is aimed at identifying the reference spectral signatures composing an hyperspectral image -- referred to as endmembers -- and their relative abundance fractions in each pixel. In practice, the identified signatures may vary spectrally from an image to another due to varying acquisition conditions inducing possibly significant estimation errors. Against this background, hyperspectral unmixing of several images acquired over the same area is of considerable interest. Indeed, such an analysis enables the endmembers of the scene to be tracked and the corresponding endmember variability to be characterized. Sequential endmember estimation from a set of hyperspectral images is expected to provide improved performance when compared to methods analyzing the images independently. However, the significant size of hyperspectral data precludes the use of batch procedures to jointly estimate the mixture parameters of a sequence of hyperspectral images. Provided that each elementary component is pre...

    Full Text Available With the development of and advances in smartphones and global positioning system (GPS devices, travelers’ long-term travel behaviors are not impossible to obtain. This study investigates the pattern of individual travel behavior and its correlation with social-demographic features. For different social-demographic groups (e.g., full-time employees and students, the individual travel behavior may have specific temporal-spatial-mobile constraints. The study first extracts the home-based tours, including Home-to-Home and Home-to-Non-Home, from long-term raw GPS data. The travel behavior pattern is then delineated by home-based tour features, such as departure time, destination location entropy, travel time, and driving time ratio. The travel behavior variability describes the variances of travelers’ activity behavior features for an extended period. After that, the variability pattern of an individual’s travel behavior is used for estimating the individual’s social-demographic information, such as social-demographic role, by a supervised learning approach, support vector machine. In this study, a long-term (18-month recorded GPS data set from Puget Sound Regional Council is used. The experiment’s result is very promising. The sensitivity analysis shows that as the number of tours thresholds increases, the variability of most travel behavior features converges, while the prediction performance may not change for the fixed test data.

  19. Research on PTSD prevalence in OEF/OIF Veterans: expanding investigation of demographic variables

    Directory of Open Access Journals (Sweden)

    Lynnette A. Averill

    2015-05-01

    Full Text Available Background: A series of recent articles has reported on well-designed studies examining base rates of posttraumatic stress disorder (PTSD screenings within the Operation Enduring Freedom (Afghanistan conflict/Operation Iraqi Freedom (Iraq conflict (OEF/OIF military population. Although these studies have a number of strengths, this line of research points out several key areas in need of further examination. Objective: Many OEF/OIF Veterans do not use available Veterans Affairs (VA services, especially mental health care. This highlights the need to understand the differences between those who use and do not use the VA, especially as research with pre-OEF/OIF Veterans suggests that these two groups differ in significant ways. The high rates of PTSD-related concerns in non-VA users also points to a need to understand whether—and where—Veterans are seeking care outside the VA and the accessibility of evidence-based, trauma-focused treatments in the community and private sectors. Careful examination of relationship status is also paramount as little research has examined relationship status or other relationship context issues. Social support, especially from a spouse, can buffer the development of PTSD; however, relationship discord has the potential to greatly exacerbate PTSD symptomatology. Furthermore, given the additional risk factors for sexual minority Veterans to be exposed to trauma, the 2011 repeal of the US Military “Don't Ask, Don't Tell” policy, and the emergence of the VA as likely the largest health care provider for sexual minority Veterans, it will be critically important to study the trauma and mental health experiences of this group. Conclusions: Studies that examine prevalence rates of PTSD in the returning cohort contribute significantly to our understanding of the US OEF/OIF military population. Further study of PTSD in relation to demographic variables such as VA and non-VA use, relationship status, and sexual

  20. The linear system theory's account of behavior maintained by variable-ratio schedules.

    McDowell, J J; Wixted, J T

    1988-01-01

    The mathematical theory of linear systems, which has been used successfully to describe behavior maintained by variable-interval schedules, is extended to describe behavior maintained by variable-ratio schedules. The result of the analysis is a pair of equations, one of which expresses response rate on a variable-ratio schedule as a function of the mean ratio requirement (n) that the schedule arranges. The other equation expresses response rate on a variable-ratio schedule as a function of reinforcement rate. Both equations accurately describe existing data from variable-ratio schedules. The theory accounts for two additional characteristics of behavior maintained by variable-ratio schedules; namely, the appearance of strained, two-valued (i.e., zero or very rapid) responding at large ns, and the abrupt cessation of responding at a boundary n. The theory also accounts for differences between behavior on variable-interval and variable-ratio schedules, including (a) the occurrence of strained responding on variable-ratio but not on variable-interval schedules, (b) the abrupt cessation of responding on occurrence of higher response rates on variable-ratio than on variable-interval schedules. Furthermore, given data from a series of variable-interval schedules and from a series of concurrent variable-ratio variable-interval schedules, the theory permits quantitative prediction of many properties of behavior on single-alternative variable-ratio schedules. The linear system theory's combined account of behavior on variable-interval and variable-ratio schedules is superior to existing versions of six other mathematical theories of variable-interval and variable-ratio responding.

    Full Text Available Today we see women working in almost all types of professions demonstrating that there is no gender difference in work. In fact many organisations say that women are playing a major role in uplifting the organization. This is a positive development that women are making their presence felt in different walks of life. On the other hand, for every woman there is one more background to manage. That is home and personal life. Today with increasing demands at work place, the interface between work life and personal life assumed significance which demands more attention. Different factors affect work –life balance and one set of factors could be demographic variables. The present study is undertaken to determine the relationship between the demographic variables and work life balance. Women employees in various professions like IT, BPO, Marketing, Insurance, Banking and Education at Bangalore constitute the universe for the study and a sample of 340 employees is chosen using stratified random sampling method. The hypothesis is tested using chi-square test and it has revealed that there is significant relationship between demographic variables and work life balance.

Meiteis are found to have comparatively better socio-economic condition than that of Koms. Two socio-demographic variables have emerged to influence offspring mortality among Meiteis and Koms. While among Meiteis higher socio-economic status is found to significantly reduce offspring mortality, among Koms it is the higher inbreeding which is found to significantly increase the offspring mortality.

    Full Text Available Objective: To evaluate bone mineral density (BMD in patients with ankylosing spondylitis (AS and determine its correlation with the demographic and clinical characteristics of AS. Patients and Methods: Demographic, clinical and osteodensitometric data were evaluated in a cross-sectional study that included 136 patients with AS. Spine and hip BMD were measured by means of dual energy X-ray absorptiometry (DXA. Using the modified Schober’s test we assessed spine mobility. We examined the sacroiliac, anteroposterior and lateral dorso-lumbar spine radiographs in order to grade sacroiliitis and assess syndesmophytes. Disease activity was evaluated using C-reactive protein (CRP levels and erythrocyte sedimentation rate (ESR. Demographic data and BMD measurements were compared with those of 167 age- and sex-matched healthy controls. Results: Patients with AS had a significantly lower BMD at the spine, femoral neck, trochanter and total hip as compared to age-matched controls (all p<0.01. According to the WHO classification, osteoporosis was present in 20.6% of the AS patients at the lumbar spine and in 14.6% at the femoral neck. There were no significant differences in BMD when comparing men and women with AS, except for trochanter BMD that was lower in female patients. No correlations were found between disease activity markers (ESR, CRP and BMD. Femoral neck BMD was correlated with disease duration, Schober’s test and sacroiliitis grade. Conclusion: Patients with AS have a lower spine and hip BMD as compared to age- and sex-matched controls. Bone loss at the femoral neck is associated with disease duration and more severe AS.

    Socioeconomic and demographic factors have been found to significantly affect time-activity patterns in population cohorts that can subsequently influence personal exposures to air pollutants. This study investigates relationships between personal exposures to eight VOCs (benzene, toluene, ethylbenzene, o-xylene, m-,p-xylene, chloroform, 1,4-dichlorobenzene, and tetrachloroethene) and socioeconomic, demographic, time-activity pattern factors using data collected from the 1999-2000 National Health and Nutrition Examination Survey (NHANES) VOC study. Socio-demographic factors (such as race/ethnicity and family income) were generally found to significantly influence personal exposures to the three chlorinated compounds. This was mainly due to the associations paired by race/ethnicity and urban residence, race/ethnicity and use of air freshener in car, family income and use of dry-cleaner, which can in turn affect exposures to chloroform, 1,4-dichlorobenzene, and tetrachloroethene, respectively. For BTEX, the traffic-related compounds, housing characteristics (leaving home windows open and having an attached garage) and personal activities related to the uses of fuels or solvent-related products played more significant roles in influencing exposures. Significant differences in BTEX exposures were also commonly found in relation to gender, due to associated significant differences in time spent at work/school and outdoors. The coupling of Classification and Regression Tree (CART) and Bootstrap Aggregating (Bagging) techniques were used as effective tools for characterizing robust sets of significant VOC exposure factors presented above, which conventional statistical approaches could not accomplish. Identification of these significant VOC exposure factors can be used to generate hypotheses for future investigations about possible significant VOC exposure sources and pathways in the general U.S. population.

    It is considered that the lifestyle conditioned by socio-demographic or socio-economic factors determines the health condition of people to the greatest extent. The aim of this study is to evaluate the influence of selected socio-demographic factors on the kinds of symptoms occurring during menopause. The study group consisted of 210 women aged 45 to 65, not using hormone replacement therapy, staying at healthcare centers for rehabilitation treatment. The study was carried out in 2013-2014 in the Silesian, Podlaskie and Lesser Poland voivodeships. The set of tools consisted of the authors' own survey questionnaire and the Menopause Rating Scale (MRS). The most commonly occurring symptom in the group of studied women was a depressive mood, from the group of psychological symptoms, followed by physical and mental fatigue, and discomfort connected with muscle and joint pain. The greatest intensity of symptoms was observed in the group of women with the lowest level of education, reporting an average or bad material situation, and unemployed women. An alarmingly high number of reported psychological symptoms in the group of menopausal women was observed, and in particular among the group of low socio-economic status. Career seems to be a factor reducing the risk of occurrence of psychological symptoms. There is an urgent need for health promotion and prophylaxis in the group of menopausal women, and in many cases for implementation of specialist psychological assistance.

    2009-06-01

    Using data from the 2004 and 2005 Consumer Expenditure Surveys (CES) comprising of 15,000 respondents, this study examines two research questions. The first of these considers the demographic differences between households whose members lose money playing the lottery and/or engaging in pari-mutuel betting and those whose members do not lose money participating in such activities. The second assesses demographic differences among households whose members lose money playing the lottery and/or engaging in pari-mutuel betting. It was found that respondents living in money-losing households are slightly older, better off financially, more likely to be married or divorced, more likely to live in a state with at least one legal casino and more likely to live in the Northeast than respondents living in non-money-losing households. Among those living in money-losing households, the least wealthy and African American respondents are more likely to lose a higher proportion of their respective incomes purchasing lottery tickets and engaging in pari-mutuel betting than wealthier respondents and whites.

    Effects of Socio-economic and Demographic Variables on Meat Consumption in Vietnam

    2014-01-01

    Full Text Available This study relates social-demographic characteristics of Vietnamese households to their consumption of meat. Pork and poultry constitute the majority of meat consumed in Vietnamese households. Hence, pork and poultry consumption have great influence on the total amount of meat consumed. Increasing pork and poultry consumption has strongly contributed to the total meat consumption growth. Tobit models are estimated drawing on the latest Vietnamese Household Living Standard Survey in 2010. The analysis of demand for pork and poultry in Vietnamese households demonstrates that meat demand in Vietnam is significantly affected by socio-economic and demographic factors of households. Understanding meat consumption patterns will help the Vietnamese government to implement policies to ensure food security. The policies may affect food redistribution between rural and urban areas, ethnic groups, the poor and the rich. In addition, food firms who wish to invest in the food market in Vietnam have to understand meat consumption patterns and meat demand to develop suitable business strategies and thereby contribute to increasing food security. This opens possibilities for domestic meat supply chains like feed producers and other livestock input suppliers, agricultural producers, processors, traders and the retail sector to take advantage of this dynamic markets sector.

    The growing shortage in human organs has raised serious concerns. To address this problem, we examine in this article the association between demographic and socioeconomic factors, and respondents' willingness to donate cadaveric organs using a large survey of Malaysian adults aged 18 years and above.A convenience sampling method was used to extract information from a total of 10,350 participants from Metropolitan Kuala Lumpur over the period of April 2, 2013 to February 29, 2014. In addition to analyzing the data using incidence of willingness to donate by demographic and socioeconomic factors, we carried out logistic regression analysis to estimate the odds ratio of respondents' willingness to become cadaveric organ donors controlling for age.About less than a third of the participants pledged to donate their organs upon death with women (35.6%) showing a higher incidence compared with men (33.2%). The Chinese (35.7%) and Malays (35.0%) pledged to contribute more than the Indians (31.6%) and the logistic regressions show that Malays (adjusted odds ration [OR] = 1.18) and Chinese (adjusted OR = 1.21) are more likely to donate than Indians (reference group). The results by religion were significant among Muslims and Hindus but not Buddhists. The likelihood of Muslims donating was the lowest (adjusted OR = 0.26). Income was also highly significant but the relationship with willingness to donate was negative. Against tertiary education, all other occupations were significant. However, the respondents with primary education enjoyed the highest adjusted OR (5.46) whereas that of secondary (0.48) and higher secondary (0.83) education was low. Among occupations (against supervisory, clerical, and direct workers), it was significant only among the unemployed and managers with adjusted OR of 1.50 and 1.58, respectively.Sex, education, ethnicity, religion, and income are important demographic and socioeconomic influences on the likelihood of Malaysians willing to become

To address this problem, we examine in this article the association between demographic and socioeconomic factors, and respondents’ willingness to donate cadaveric organs using a large survey of Malaysian adults aged 18 years and above. A convenience sampling method was used to extract information from a total of 10,350 participants from Metropolitan Kuala Lumpur over the period of April 2, 2013 to February 29, 2014. In addition to analyzing the data using incidence of willingness to donate by demographic and socioeconomic factors, we carried out logistic regression analysis to estimate the odds ratio of respondents’ willingness to become cadaveric organ donors controlling for age. About less than a third of the participants pledged to donate their organs upon death with women (35.6%) showing a higher incidence compared with men (33.2%). The Chinese (35.7%) and Malays (35.0%) pledged to contribute more than the Indians (31.6%) and the logistic regressions show that Malays (adjusted odds ration [OR] = 1.18) and Chinese (adjusted OR = 1.21) are more likely to donate than Indians (reference group). The results by religion were significant among Muslims and Hindus but not Buddhists. The likelihood of Muslims donating was the lowest (adjusted OR = 0.26).

  19. Anatomy of a population cycle: the role of density dependence and demographic variability on numerical instability and periodicity.

    Determining the causes of cyclic fluctuations in population size is a central tenet in population ecology and provides insights into population regulatory mechanisms. We have a firm understanding of how direct and delayed density dependence affects population stability and cyclic dynamics, but there remains considerable uncertainty in the specific processes contributing to demographic variability and consequent change in cyclic propensity. Spatiotemporal variability in cyclic propensity, including recent attenuation or loss of cyclicity among several temperate populations and the implications of habitat fragmentation and climate change on this pattern, highlights the heightened need to understand processes underlying cyclic variation. Because these stressors can differentially impact survival and productivity and thereby impose variable time delays in density dependence, there is a specific need to elucidate how demographic vital rates interact with the type and action of density dependence to contribute to population stability and cyclic variation. Here, we address this knowledge gap by comparing the stability of time series derived from general and species-specific (Canada lynx: Lynx canadensis; small rodents: Microtus, Lemmus and Clethrionomys spp.) matrix population models, which vary in their demographic rates and the direct action of density dependence. Our results reveal that density dependence acting exclusively on survival as opposed to productivity is destabilizing, suggesting that a shift in the action of population regulation toward reproductive output may decrease cyclic propensity and cycle amplitude. This result was the same whether delayed density dependence was pulsatile and acted on a single time period (e.g. t-1, t-2 or t-3) vs. more constant by affecting a successive range of years (e.g. t-1,…, t-3). Consistent with our general models, reductions in reproductive potential in both the lynx and small rodent systems led to notably large drops in

    Work-related stress is widely recognized as one of the major challenges to occupational health and safety. The correlation between work-related stress risk factors and physical health outcomes is widely acknowledged. This study investigated socio-demographic and occupational variables involved in perceived risk of work-related stress. The Italian version of the Health and Safety Executive Management Standards Indicator Tool was used in a large survey to examine the relationship between work-related stress risks and workers' demographic and occupational characteristics. Out of 8,527 questionnaires distributed among workers (from 75 organizations) 6,378 were returned compiled (74.8%); a set of mixed effects models were adopted to test single and combined effects of the variables on work-related stress risk. Female workers reported lower scores on control and peer support and more negative perceptions of relationships and change at work than male workers, most of them with full-time contracts. Age, job seniority, and educational level appeared positively correlated with control at work, but negatively with job demands. Fixed-term workers had positive perceptions regarding job demands and relationships, but more difficulties about their role at work than permanent workers. A commuting time longer than one hour and shift work appeared to be associated with higher levels of risk factors for work-related stress (except for role), the latter having more negative effects, increasing with age. The findings suggest that the assessment and management of work-related stress risk should consider specific socio-demographic and occupational risk factors such as gender, age, educational level, job status, shift work, commuting time, job contracts.

    The present study's aim was to examine effects of cancer patients' perceived distress and problems, socio-demographic and illness-related variables and social support sufficiency on referral wish. A cross-sectional group of 1340 patients (response = 51%) completed a questionnaire consisting of the Dutch version of the Distress Thermometer and Problem List, including the referral wish question, and questions on socio-demographic and illness-related variables and perceived social support sufficiency. Univariate and multivariate analyses were performed to investigate the effects of these variables on patients' referral wish. Of the patients who completed the referral wish question (N = 1297), 13% wished and 21% considered a referral, while 66% did not want a referral. Univariate analyses showed that, in comparison with patients not having a referral wish, those having a (maybe) wish were more distressed, reporting more problems in all Problem List domains, younger, more likely not to have children or children living at home, higher educated, more likely to be employed, under active treatment or recently diagnosed, receiving more intensive treatment and more likely to perceive support received to be insufficient. A final ordinal logistic regression analysis showed independent effects of distress, practical and emotional problems, age and treatment phase on referral wish (χ(2) (6) = 205.9; p < 0.001; Nagelkerke's R(2)  = 0.24). A third of the patients (maybe) wished a referral. Knowledge of risk variables (particularly increased distress, experience of more practical and emotional problems, younger age and receiving active treatment or recently diagnosed) may support the identification of patients at increased need of additional healthcare services.

    A large group of women (20-30 %) report psychological distress shortly after breast cancer diagnosis, and some experience continued or increased symptoms over time. The aim of this study was to investigate socio-demographic and clinical variables associated with sustained psychological distress in this patient group. Women with breast cancer (n = 833) completed self-report questionnaires regarding socio-demographic and clinical variables shortly after (T1) and 3 years after diagnosis (T2) while data on illness severity were collected from a quality register. The Hospital Anxiety and Depression Scale was used as a measure of psychological distress at both time points. The number of participants who reported elevated levels of anxiety was 231 (28 %) at T1 and 231 (28 %) at T2 while elevated depressive symptoms was reported by 119 (14 %) women at T1 and 92 (11 %) at T2. Despite non-significant differences in mean scores over time, 91 (15 %) participants reported increased anxiety symptoms and 47 (7 %) reported increased depressive symptoms. Poor financial situation, lack of social support, previous psychiatric treatment, and high levels of fatigue were associated with both anxiety and depressive symptoms. Reporting high levels of fatigue was the variable most strongly associated with increased psychological distress over time. Most participants reported decreased psychological distress over time, but there were subgroups of women who experienced sustained or increased symptoms of anxiety or depression. Participants with poor financial status, previous psychological problems, or high levels of fatigue may be at increased risk of psychological distress. Such individuals may benefit most from psychosocial interventions.

    Full Text Available The proportion of elderly people is growing faster than any other age group. Amongst them, the group of oldest old is indeed the segment of the elderly population with the fastest growth rate. The increase in the proportion of elderly in the Angolan population makes research on this area badly needed. Within the theoretical framework of successful aging, the study aims to test for sociodemographic group differences in perceived health, life satisfaction, and social relations in Angolan elderly. The dependent variables are three of the components of what has been called successful aging. Data came from a cross-sectional survey of elderly people living in Luanda. 1003 Angolan elderly were surveyed on sociodemographic information, perceived health, life satisfaction, and social support. MANOVAs were calculated to test for mean differences in the dependent variables. Results permit to conclude that the factors associated with the largest differences on the Angolan elderly’s quality of life and social relations were age (becoming oldest old and institutionalization. The interactions of several factors with age pointed out that the oldest old were clearly a group in which the decreased quality of life due to becoming oldest old could not be compensated by other factors, as it was the case in the group of young old.

    Despite substantial attention toward environmental tobacco smoke (ETS) exposure, previous studies have not provided adequate information to apply broadly within community-scale risk assessments. We aim to estimate residential concentrations of particulate matter (PM) from ETS in sociodemographic and geographic subpopulations in the United States for the purpose of screening-level risk assessment. We developed regression models to characterize smoking using the 2006-7 Current Population Survey--Tobacco Use Supplement, and linked these with air exchange models using the 2007 American Housing Survey. Using repeated logistic and log-linear models (n = 1000), we investigated whether household variables from the 2000 United States census can predict exposure likelihood and ETS-PM concentration in exposed households. We estimated a mean ETS-PM concentration of 16 μg/m(3) among the 17% of homes with non-zero exposure (3 μg/m(3) overall), with substantial variability among homes. The highest exposure likelihood was in the South and Midwest regions, rural populations, and low-income households. Concentrations in exposed households were highest in the South and demonstrated a non-monotonic association with income, related to air exchange rate patterns. We provide estimates of ETS-PM concentration distributions for different subpopulations in the United States, providing a starting point for communities interested in characterizing aggregate and cumulative risks from indoor pollutants.

    Full Text Available Abstract Background An important challenge for transcript counting methods such as Serial Analysis of Gene Expression (SAGE, "Digital Northern" or Massively Parallel Signature Sequencing (MPSS, is to carry out statistical analyses that account for the within-class variability, i.e., variability due to the intrinsic biological differences among sampled individuals of the same class, and not only variability due to technical sampling error. Results We introduce a Bayesian model that accounts for the within-class variability by means of mixture distribution. We show that the previously available approaches of aggregation in pools ("pseudo-libraries" and the Beta-Binomial model, are particular cases of the mixture model. We illustrate our method with a brain tumor vs. normal comparison using SAGE data from public databases. We show examples of tags regarded as differentially expressed with high significance if the within-class variability is ignored, but clearly not so significant if one accounts for it. Conclusion Using available information about biological replicates, one can transform a list of candidate transcripts showing differential expression to a more reliable one.

  8. Who theorizes age? The "socio-demographic variables" device and age-period-cohort analysis in the rhetoric of survey research.

    Rughiniș, Cosima; Humă, Bogdana

    2015-12-01

    In this paper we argue that quantitative survey-based social research essentializes age, through specific rhetorical tools. We outline the device of 'socio-demographic variables' and we discuss its argumentative functions, looking at scientific survey-based analyses of adult scientific literacy, in the Public Understanding of Science research field. 'Socio-demographics' are virtually omnipresent in survey literature: they are, as a rule, used and discussed as bundles of independent variables, requiring little, if any, theoretical and measurement attention. 'Socio-demographics' are rhetorically effective through their common-sense richness of meaning and inferential power. We identify their main argumentation functions as 'structure building', 'pacification', and 'purification'. Socio-demographics are used to uphold causal vocabularies, supporting the transmutation of the descriptive statistical jargon of 'effects' and 'explained variance' into 'explanatory factors'. Age can also be studied statistically as a main variable of interest, through the age-period-cohort (APC) disambiguation technique. While this approach has generated interesting findings, it did not mitigate the reductionism that appears when treating age as a socio-demographic variable. By working with age as a 'socio-demographic variable', quantitative researchers convert it (inadvertently) into a quasi-biological feature, symmetrical, as regards analytical treatment, with pathogens in epidemiological research.

Consumers were approached at the store entrance and asked to complete a self-administered survey. Three metropolitan Minnesota grocery stores. Participants (n = 550) were adults who shopped at the store: the majority were white, female, and highly educated and earned >or= 50,000 dollars/year. Participation rates averaged 62%. The major domain investigated was consumer support for sustainably produced foods. Demographics, beliefs, attitudes, subjective norm, and self-identity and perceived behavioral control were evaluated as predictors of intention to purchase them. Descriptive statistics, independent t tests, one-way analysis of variance, Pearson product moment correlation coefficients, and stepwise multiple regression analyses (P Consumers were supportive of sustainably produced foods but not highly confident in their ability to purchase them. Independent predictors of intention to purchase them included attitudes, beliefs, perceived behavioral control, subjective norm, past buying behavior, and marital status. Beliefs, attitudes, and confidence level may influence intention to purchase sustainably produced foods. Nutrition educators could increase consumers' awareness of sustainably produced foods by understanding their beliefs, attitudes, and confidence levels.

    Spanish is the fourth most spoken language in the world, and the majority of Spanish speakers have a Latin American origin. Reading aloud infrequently accentuated words has been established as a National Adult Reading Test-like method to assess premorbid intelligence in Spanish. However, several versions have been proposed and validated with small and selected samples, in particular geographical conditions, and they seldom derive a formula for IQ estimation with the Wechsler Adult Intelligence Scale (WAIS) Full-Scale IQ (FSIQ). The objective of this study was to develop equations to estimate WAIS-Third Edition (WAIS-III) FSIQ from the Word Accentuation Test-Revised (WAT-R), demographic variables, and their combination within diverse Latin American samples. Two hundred and forty participants from Argentina and Colombia, selected according to age and years of education strata, were assessed with the WAT-R, the WAIS-III, and a structured questionnaire about demographic and medical information. A combined approach including place of birth, years of education, and WAT-R provided the best equation, explaining 76% of IQ variance. These equations could be useful for estimating premorbid IQ in patients with Latin American Spanish as their birth language.

    This study examined the association between socio-demographic factors (educational level and employment status) and the nutritional and immune status of 35 HIV-positive/AIDS patients at baseline. Assessment of selected macro-and micronutrient dietary intake was done using a validated food frequency questionnaire. Evaluation of anthropometric profiles (body mass index, waist-hip ratio and percentage of body fat) was also evaluated. A questionnaire was applied to obtain information on the educational level and employment status of the patients. The CD4+ T-cell counts and viral loads of the same patients were determined using the flow cytometry and Polymerase Chain Reaction (PCR) method respectively. An association between educational level and dietary intake was significant (p 0.05) association between the two socio-demographic variables (education and employment) and anthropometric profiles. The association between education, employment and CD4+ T-cell count was not significant (p > 0.05). The viral load showed a significant (p nutritional and immune status. It is suggested that the results of this study should be interpreted with caution. Further studies with larger sample sizes are recommended.

    1. It is widely accepted that density-dependent processes play an important role in most natural populations. However, persistent challenges in our understanding of density-dependent population dynamics include evaluating the shape of the relationship between density and demographic rates (linear, concave, convex), and identifying extrinsic factors that can mediate this relationship. 2. I studied the population dynamics of the cactus bug Narnia pallidicornis on host plants (Opuntia imbricata) that varied naturally in relative reproductive effort (RRE, the proportion of meristems allocated to reproduction), an important plant quality trait. I manipulated per-plant cactus bug densities, quantified subsequent dynamics, and fit stage-structured models to the experimental data to ask if and how density influences demographic parameters. 3. In the field experiment, I found that populations with variable starting densities quickly converged upon similar growth trajectories. In the model-fitting analyses, the data strongly supported a model that defined the juvenile cactus bug retention parameter (joint probability of surviving and not dispersing) as a nonlinear decreasing function of density. The estimated shape of this relationship shifted from concave to convex with increasing host-plant RRE. 4. The results demonstrate that host-plant traits are critical sources of variation in the strength and shape of density dependence in insects, and highlight the utility of integrated experimental-theoretical approaches for identifying processes underlying patterns of change in natural populations.

    Overweight and obesity is a growing problem for children in foster care. This study describes the prevalence of overweight and obesity in an urban, ethnic minority population of children ages 2-19 in long-term foster care (N = 312) in Los Angeles, California. It also investigates whether demographics or placement settings are related to high body mass index. The estimates of prevalence of overweight/obesity (≥85th percentile) and obesity (≥95th percentile) were presented for gender, age, ethnicity, and placement type. Multiple logistic regression was used to examine potential associations between demographic and placement variables and weight status. The prevalence of overweight/obesity was almost 40 % and obesity was 23 % for the study population. Children placed in a group home had the highest prevalence of overweight/obesity (60 %) and obesity (43 %) compared to other types of placement. Within this study, older children (ages 12-19) were more likely to be overweight/obese than normal weight compared to children between 2 and 5 years old when controlling for gender, ethnicity and placement (OR = 2.10, CI = 1.14-3.87). These findings suggest that older age and long-term foster care in general may be risk factors for obesity. Child welfare agencies and health care providers need to work together to train caregivers with children in long-term foster care in obesity treatment interventions and obesity prevention strategies.

    Full Text Available Abstract Background Burns are a persisting public health problem in low- and middle-income countries; however, epidemiologic data for these settings is scarce. South Africa is no exception although there is an emerging knowledge base, especially for paediatric burns. The current study describes the epidemiology of burn mortality across the lifespan in Cape Town (2.9 million inhabitants in 2001, one of the six South African metropolitan centres. Methods The distribution of burn mortality across socio-demographic groups and also their circumstances of occurrence were investigated using four year (2001 to 2004 surveillance data from the National Injury Mortality Surveillance System (n = 1024 cases. Results Burn mortality occurred at a rate of 7.9 per 100 000 person-years (95% CI: 7.3-8.3. Males sustained fatal rates 2.2 times more than that for females (p Conclusion Besides paediatric burns, the high prevalence and circumstances of occurrence of burns among middle age men are a source of concern. There are reasons to believe that this over-representation is a reflection of detrimental living conditions, life-style and poor socio-economic status. It is recommended that there be greater prioritisation of prevention activities that involve the control or management of kerosene heat sources, the provision of alternatives to flammable housing materials, and the implementation of strategies to reduce harmful drinking practices.

    This sectional study was performed with the objective to verify the association between the forms of coping used by people on chronic hemodialysis and their socio-demographic variables. A semi-structured instrument and the Folkman and Lazarus' Coping Strategies Inventory were used. The sample consisted of 107 adults, mostly male (62.4%), on ambulatory hemodialysis for over six months. The most commonly referred forms of coping were related to the positive reevaluation factor (coping centered on emotions); with the highest mean scores among women for all factors and for people who reported having a partner, living with their families and receiving support in their treatment, and the highest scores were common for the factors control, self-control, and social support. Knowing the forms of coping prepares nurses to reinforce or seek, with patients on hemodialysis, choosing positive forms of coping and propose actions that permit patients to develop adaptive mechanisms.

    Full Text Available Objective: The aim of this study was to describe relationships between self-reported diabetes mellitus and its treatment, according to demographic and socioeconomic data, as well as indicators of nutritional status in community-dwelling older adults. Methods: This is a population-based and a cross-sectional study derived from the multicentric survey "Frailty in Brazilian Elderly". The random sample consisted of 881 community-dwelling older adults aged 65 years and older from the city of Campinas. The self-reported variables were: age, gender, family income (minimum salaries, education (years of education; and absolute data (yes versus no regarding unintentional weight loss and weight gain, diabetes, and its treatment. Anthropometric variables were collected by trained examiners following classic protocols. Body mass index was classified as: underweight 1.00 and >0.90. Results: The variables most associated with diabetes were obesity (OR=2.19, abdominal adiposity (OR=2.97, and unintentional weight loss (OR=3.38. The lack of diabetes treatment was associated with advanced age (p=0.027, lower educational level (p=0.005, and low metabolic risk (p=0.004. Conclusion: Self-reported diabetes was associated with obesity but mostly with abdominal adiposity and unintentional weight loss. Not being treated for diabetes mellitus was associated with advanced age, lower levels of education, and lower abdominal adiposity.

    Full Text Available Purpose of the study: Noting that the motive for shopping is located within the paradigm of buying behaviour of consumers; the study seeks to complement existing literature by examining whether a configuration of shopper motives could be developed, thereby revealing taxonomy of hypermarket (hyper-store shoppers. In addition the study seeks to establish whether shopping motives is shaped by demographic variables. Problem statement: Although the motive for shopping and its antecedents has been approached from various perspectives, it has been accentuated in literature that traditional utilitarian aspects of product acquisition explanations may not fully reflect the totality of a shopping experience. With such affirmations, shopping may be harmonised with hedonic activities when considered within a hypermarket/hyper-store South African context. Methodology: The study adopted a conceptual framework for identifying relatable factors (using exploratory factor analysis that influence consumer motivation for shopping within hypermarket (hyper-store environments. Reliability and validity of the scale was established. Findings: A 13 item scale was developed. Shopping seems to be both a utilitarian and a hedonic consumption experience with three auxiliary categories of hedonic motivations, namely diversion, recreational and sensory stimulated shoppers. In examining the motives for shopping and demographic variables, diversion appears to vary with levels of education. Value of the research: Enhancing one's understanding of the "softer" issues of shopping, namely diversion, recreational and sensory stimulated shoppers is essential, as they represent possible differentiating factors in a highly competitive and often commoditised retail market. Acquaintance of distinct shopper segments is useful for retailers in assembling marketing communication strategies and designing appealing store environments. Conclusion: Whilst shopper typologies may hold several

    Full Text Available The central objective of this study is to identify and analyze the intervening variables that influence ethical decision making of accounting professionals, in a region in the state of Rio Grande do Sul, Brazil. The methodology is quantitative and descriptive exploratory. The technical procedures include the use of questionnaires with response linked to Likert scale, comprising a sample unit of 122 professional accounting, and analysis occurs through non-parametric statistics, such as logistic regression and Spearman correlation. The results reveal that the accounting professionals who agree fully with the importance of the Counter Code of Professional Ethics (CEPC as a guide to conduct 59% and stick to it in decision making in 63.9%. The logistic regression model predicted that professionals meet the CEPC and do not meet respectively with a certainty of 87.5% and 100%. The attitudes towards CEPC these accounting professionals can be explained by the importance and use this as a guide of conduct, with a 95.5% prediction sure. The intervening variables that were significant at 0.01 and 0.05 in the CEPC compliance relating to religiosity, relevance and assistance that the code provides the professional conduct. It follows that the ethical decision making of the accounting professional is influenced by their religion and relevance and assistance that the CEPC provides for this professional.

  2. Taking purpose into account in experimental psychology: testing for controlled variables.

    2013-02-01

    Experimental research in psychology is based on a causal model--the General Linear Model (GLM)--that assumes behavior has causes but not purposes. Powers (1978) used a control theory analysis to show that the results of psychological experiments based on such a model can be misleading if the organisms being studied are purposeful (control) systems. In the same paper, Powers presented evidence that organisms are such systems. Nevertheless, psychologists continue to use methods that ignore purpose because the behavior in most experiments appears to be non-purposeful (a caused result of variations in the independent variable). The experiments described in this paper show how purposeful behavior can appear to be caused by the independent variable when an organism's purposes are ignored. The results show how taking purpose into account using the control theory-based "Test for the Controlled Variable" can provide a productive new methodological direction for experimental research in psychology.

    The present study examined change on emotional distress of sarcoma patients from the diagnostic to treatment phases, the distinct trajectories of adjustment and the influence of demographic, clinical and coping variables on anxiety and depression. Thirty-six sarcoma patients completed questionnaires on emotional distress (Hospital Anxiety and Depression Scale) and coping strategies (Brief Cope) at time of diagnosis, and again during treatment. No significant change in emotional distress levels was found from diagnostic to treatment phase, with mean anxiety and depression scores remaining below the clinical range. Over time, 52.8% and 66.7% of patients maintained non-clinical anxious and depressive symptoms respectively, and 25% and 11.1% remained with clinical anxiety and depression. Living with partner, less use of humour and more denial were associated with high emotional distress at time of diagnosis and during treatments, and high levels of distress at baseline were predictive of poorer emotional adjustment during treatments. Although sarcoma patients, in general, seem to exhibit good psychological adjustment, there is a significant minority that requires mental health services in order to help decrease their emotional distress following the diagnosis, and prevent psychological difficulties during treatments. Our findings are an important contribution to understanding the psychological adjustment of patients with a specific and rare type of cancer.

    This paper presents a study on the specific behavior of the Boost DC-DC converters generally used for powering conversion of PV panels connected to a HVDC (High Voltage Direct Current) Bus. It follows some works pointing out that converter MPPT (Maximum Power Point Tracker) is severely perturbed by output voltage variations due to physical dependency of parameters as the input voltage, the output voltage and the duty cycle of the PWM switching control of the MPPT. As a direct consequence many converters connected together on a same load perturb each other because of the output voltage variations induced by fluctuations on the HVDC bus essentially due to a not insignificant bus impedance. In this paper we show that it is possible to include an internal computed variable in charge to compensate local and external variations to take into account the environment variables.

    Behmanesh, Iman; Moaveni, Babak

    2016-07-01

    This paper presents a Hierarchical Bayesian model updating framework to account for the effects of ambient temperature and excitation amplitude. The proposed approach is applied for model calibration, response prediction and damage identification of a footbridge under changing environmental/ambient conditions. The concrete Young's modulus of the footbridge deck is the considered updating structural parameter with its mean and variance modeled as functions of temperature and excitation amplitude. The identified modal parameters over 27 months of continuous monitoring of the footbridge are used to calibrate the updating parameters. One of the objectives of this study is to show that by increasing the levels of information in the updating process, the posterior variation of the updating structural parameter (concrete Young's modulus) is reduced. To this end, the calibration is performed at three information levels using (1) the identified modal parameters, (2) modal parameters and ambient temperatures, and (3) modal parameters, ambient temperatures, and excitation amplitudes. The calibrated model is then validated by comparing the model-predicted natural frequencies and those identified from measured data after deliberate change to the structural mass. It is shown that accounting for modeling error uncertainties is crucial for reliable response prediction, and accounting only the estimated variability of the updating structural parameter is not sufficient for accurate response predictions. Finally, the calibrated model is used for damage identification of the footbridge.

  11. Accounting for sampling variability, injury under-reporting, and sensor error in concussion injury risk curves.

    There has been recent dramatic increase in the use of sensors affixed to the heads or helmets of athletes to measure the biomechanics of head impacts that lead to concussion. The relationship between injury and linear or rotational head acceleration measured by such sensors can be quantified with an injury risk curve. The utility of the injury risk curve relies on the accuracy of both the clinical diagnosis and the biomechanical measure. The focus of our analysis was to demonstrate the influence of three sources of error on the shape and interpretation of concussion injury risk curves: sampling variability associated with a rare event, concussion under-reporting, and sensor measurement error. We utilized Bayesian statistical methods to generate synthetic data from previously published concussion injury risk curves developed using data from helmet-based sensors on collegiate football players and assessed the effect of the three sources of error on the risk relationship. Accounting for sampling variability adds uncertainty or width to the injury risk curve. Assuming a variety of rates of unreported concussions in the non-concussed group, we found that accounting for under-reporting lowers the rotational acceleration required for a given concussion risk. Lastly, after accounting for sensor error, we find strengthened relationships between rotational acceleration and injury risk, further lowering the magnitude of rotational acceleration needed for a given risk of concussion. As more accurate sensors are designed and more sensitive and specific clinical diagnostic tools are introduced, our analysis provides guidance for the future development of comprehensive concussion risk curves.

    Full Text Available For approval of generic drugs, the FDA requires that evidence of bioequivalence in average bioequivalence in terms of drug absorption be provided through the conduct of a bioequivalence study. A test product is said to be average bioequivalent to a reference (innovative product if the 90% confidence interval of the ratio of means (after log-transformation is totally within (80%, 125%. This approach is considered a one-parameter approach, which does not account for possible heterogeneity of variability between drug products. In this paper, we study a two-parameter approach (i.e., confidence region approach for assessing bioequivalence, which can also be applied to assessing biosimilarity of biosimilar products. The proposed confidence region approach is compared with the traditional one-parameter approach both theoretically and numerically (i.e., simulation study for finite sample performance.

    Inconsistencies in reports on methamphetamine (METH) associated cognitive dysfunction may be attributed, at least in part, to the diversity of study sample features (eg, clinical and demographic characteristics). The current study assessed cognitive function in a METH-dependent population from rural South Carolina, and the impact of demographic and clinical characteristics on performance. Seventy-one male (28.2%) and female (71.8%) METH-dependent subjects were administered a battery of neurocognitive tests including the Test of Memory Malingering (TOMM), Shipley Institute of Living Scale, Paced Auditory Serial Addition Test (PASAT), Symbol Digit Modalities Test (SDMT), Grooved Pegboard Test, California Verbal Learning Test (CVLT), and Wisconsin Card Sorting Test (WCST). Demographic and clinical characteristics (eg, gender, frequency of METH use) were examined as predictors of performance. Subjects scored significantly lower than expected on one test of attention and one of fine motor function, but performed adequately on all other tests. There were no predictors of performance on attention; however, more frequent METH use was associated with better performance for males and worse for females on fine motor skills. The METH-dependent individuals in this population exhibit very limited cognitive impairment. The marked differences in education, Intellectual Quotient (IQ), and gender in our sample when compared to the published literature may contribute to these findings. Characterization of the impact of clinical and/or demographic features on cognitive deficits could be important in guiding the development of treatment interventions. © American Academy of Addiction Psychiatry.

  16. Targeted computational probabilistic corroboration of experimental knee wear simulator: the importance of accounting for variability.

    Experimental testing is widely used to predict wear of total knee replacement (TKR) devices. Computational models cannot replace this essential in vitro testing, but they do have complementary strengths and capabilities, which make in silico models a valuable support tool for experimental wear investigations. For effective exploitation, these two separate domains should be closely corroborated together; this requires extensive data-sharing and cross-checking at every stage of simulation and testing. However, isolated deterministic corroborations provide only a partial perspective; in vitro testing is inherently variable, and relatively small changes in the environmental and kinematic conditions at the articulating interface can account for considerable variation in the reported wear rates. Understanding these variations will be key to managing uncertainty in the tests, resulting in a 'cleaner' investigation environment for further refining current theories of wear. This study demonstrates the value of probabilistic in silico methods by describing a specific, targeted corroboration of the AMTI knee wear simulator, using rigid body dynamics software models. A deterministic model of the simulator under displacement-control was created for investigation. Firstly, a large sample of experimental data (N>100) was collated, and a probabilistic computational study (N>1000 trials) was used to compare the kinetic performance envelopes for in vitro and in silico models, to more fully corroborate the mechanical model. Secondly, corresponding theoretical wear-rate predictions were compared to the experimentally reported wear data, to assess the robustness of current wear theories to uncertainty (as distinct from the mechanical variability). The results reveal a good corroboration for the physical mechanics of the wear test rig; however they demonstrate that the distributions for wear are not currently well-predicted. The probabilistic domain is found to be far more sensitive at

    Sterba, Sonya K; Rights, Jason D

    2016-01-01

    Item parceling remains widely used under conditions that can lead to parcel-allocation variability in results. Hence, researchers may be interested in quantifying and accounting for parcel-allocation variability within sample. To do so in practice, three key issues need to be addressed. First, how can we combine sources of uncertainty arising from sampling variability and parcel-allocation variability when drawing inferences about parameters in structural equation models? Second, on what basis can we choose the number of repeated item-to-parcel allocations within sample? Third, how can we diagnose and report proportions of total variability per estimate arising due to parcel-allocation variability versus sampling variability? This article addresses these three methodological issues. Developments are illustrated using simulated and empirical examples, and software for implementing them is provided.

    Full Text Available The purpose of this study is to identify the kindergarten students’ levels of understanding some science concepts (LUSSC and scientific inquiry processes (SIP and compare their LUSSC and SIP in terms of some demographic variables. Also, another purpose of this study is to identify the predictive power of those demographic variables over the kindergarten students’ LUSSC and SIP. This study was conducted according to quantitative research design. The study group consisted of 335 kindergarten students from 20 different rural and urban schools. In the study, the scale for “Turkish Kindergarten Students’ Understandings of Scientific Concepts and Scientific Inquiry Processes” was used. According to some variables (such as mother’s education level and family structure, there was a statistically significant difference between students’ mean scores for LUSSC and between students’ mean scores for SIP. Within the scope of this study, it was found that among the predictor variables (age, family’s income level, and number of brother/sister were significant predictors for LUSSC, and number of brother/sister was a significant predictor for SIP.

    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.

    Measures of satisfaction of surgical patients can be used to evaluate and redesign the process of care or to complement established procedures to improve quality of services. However, study findings regarding aspects of patient satisfaction are often inconsistent and depend on the setting. The primary goals of this research were to identify factors associated with satisfaction among patients in a surgical setting. Data used in this study were obtained from randomly selected 2699 surgical patients discharged during January-December 2008 from 26 hospitals who responded to a mailed survey. The instrument assessed satisfaction regarding 23 items of perceived care, patient demographic, and visit characteristics. Bivariate and multivariate techniques were used to reveal relations between indicators and overall satisfaction. Bivariate statistics showed strong relations between overall satisfaction and perceived care with weaker findings pertaining to demographic and visit characteristics. The Multivariate logistic regression predicting overall satisfaction demonstrated that patients receiving surgical services predominantly have similar demands and priorities regardless of age and gender. The strongest factors were (P < 0.05) the interpersonal manner of medical practitioners and nurses, organization of operations, admittance, and discharge, as well as perceived length of stay. This study identified factors that are related to satisfaction of surgical patients and indicated the intensity of this relationship. These findings support health care providers and medical practitioners with valuable information to meet needs and preferences of patients receiving surgical services. Copyright © 2010 Elsevier Inc.

    Helicoverpa armigera is one of the primary agricultural pests in the Old World, whereas H. zea is predominant in the New World. However, H. armigera was first documented in Brazil in 2013. Therefore, the geographical distribution, range of hosts, invasion source, and dispersal routes for H. armigera are poorly understood or unknown in Brazil. In this study, we used a phylogeographic analysis of natural H. armigera and H. zea populations to (1) assess the occurrence of both species on different hosts; (2) infer the demographic parameters and genetic structure; (3) determine the potential invasion and dispersal routes for H. armigera within the Brazilian territory; and (4) infer the geographical origin of H. armigera. We analyzed partial sequence data from the cytochrome c oxidase subunit I (COI) gene. We determined that H. armigera individuals were most prevalent on dicotyledonous hosts and that H. zea were most prevalent on maize crops, based on the samples collected between May 2012 and April 2013. The populations of both species showed signs of demographic expansion, and no genetic structure. The high genetic diversity and wide distribution of H. armigera in mid-2012 are consistent with an invasion period prior to the first reports of this species in the literature and/or multiple invasion events within the Brazilian territory. It was not possible to infer the invasion and dispersal routes of H. armigera with this dataset. However, joint analyses using sequences from the Old World indicated the presence of Chinese, Indian, and European lineages within the Brazilian populations of H. armigera. These results suggest that sustainable management plans for the control of H. armigera will be challenging considering the high genetic diversity, polyphagous feeding habits, and great potential mobility of this pest on numerous hosts, which favor the adaptation of this insect to diverse environments and control strategies.

    Caesarean section (CS) rate is a quality of health care indicator frequently used at national and international level. The aim of this study was to assess whether adjustment for Robson's Ten Group Classification System (TGCS), and clinical and socio-demographic variables of the mother and the fetus is necessary for inter-hospital comparisons of CS rates. The study population includes 64,423 deliveries in Emilia-Romagna between January 1, 2003 and December 31, 2004, classified according to theTGCS. Poisson regression was used to estimate crude and adjusted hospital relative risks of CS compared to a reference category. Analyses were carried out in the overall population and separately according to the Robson groups (groups I, II, III, IV and V-X combined). Adjusted relative risks (RR) of CS were estimated using two risk-adjustment models; the first (M1) including the TGCS group as the only adjustment factor; the second (M2) including in addition demographic and clinical confounders identified using a stepwise selection procedure. Percentage variations between crude and adjusted RRs by hospital were calculated to evaluate the confounding effect of covariates. The percentage variations from crude to adjusted RR proved to be similar in M1 and M2 model. However, stratified analyses by Robson's classification groups showed that residual confounding for clinical and demographic variables was present in groups I (nulliparous, single, cephalic, ≥37 weeks, spontaneous labour) and III (multiparous, excluding previous CS, single, cephalic, ≥37 weeks, spontaneous labour) and IV (multiparous, excluding previous CS, single, cephalic, ≥37 weeks, induced or CS before labour) and to a minor extent in groups II (nulliparous, single, cephalic, ≥37 weeks, induced or CS before labour) and IV (multiparous, excluding previous CS, single, cephalic, ≥37 weeks, induced or CS before labour). The TGCS classification is useful for inter-hospital comparison of CS section rates, but

    Evidence of the link between job strain and cortisol levels has been inconsistent. This could be due to failure to account for cortisol variability leading to underestimated standard errors. Our objective was to model the relationship between job strain and the whole cortisol curve, accounting for sources of cortisol variability. Our functional mixed-model approach incorporated all available data-18 samples over 3 days-and uncertainty in estimated relationships. We used employed participants from the Multi-Ethnic Study of Atherosclerosis Stress I Study and data collected between 2002 and 2006. We used propensity score matching on an extensive set of variables to control for sources of confounding. We found that job strain was associated with lower salivary cortisol levels and lower total area under the curve. We found no relationship between job strain and the cortisol awakening response. Our findings differed from those of several previous studies. It is plausible that our results were unique to middle- to older-aged racially, ethnically, and occupationally diverse adults and were therefore not inconsistent with previous research among younger, mostly white samples. However, it is also plausible that previous findings were influenced by residual confounding and failure to propagate uncertainty (i.e., account for the multiple sources of variability) in estimating cortisol features.

Shortly, a commonly shared life was born between Muslims and believers of other religions and continuedwithout an issue for a long period of time. The ethnical differences, withthe result of a weakening Ottoman Empire during the 19th century,were used by the European countries and Russia to be able to invadethe demographic structure. This was a demographic game that endedwith Turkey’s victory in 1923. As Turkey transformed into a modernnational country in 1923, Blacksea region developed into a dynamicstructure.Blacksea has provided a safe exit on terrain and marine paths forthe energy resources that were discovered around Hazar region at theend of 1990. Today, with Romania and Bulgaria being neighbors withthe European Union, energy transportation plans play a critical role.However, based on data from 2010, the ratio of amount of transportedenergy to the Turkish population is significantly low. Since the regioncarries a critical importance in energy strategy of global scale,development of energy focused opportunities need to be initiated.During the execution phase; the demographic structure, as well as thehistorical Blacksea culture, must be protected and the population of thelocal community should be increased.

    The regression results showed that gender stereotypes, sense of power and number of children were all significant predictors for demand/withdraw pattern. The correlation results showed that increasing in stereotypical thinking and the number of children can lead to an increase in the probability of demand/withdraw cycle. Also, more sense of power has a positive correlation with the “withdrawal pattern” and less sense of power has a positive correlation with the “demand pattern”. The results demonstrate that the variables which were considered in the analysis of the cycle in this research are important and can help relevant agents to provide opportunities for improving couple relationships.

    Blood miRNAs are a new promising area of disease research, but variability in miRNA measurements may limit detection of true-positive findings. Here, we measured sources of miRNA variability and determine whether repeated measures can improve power to detect fold-change differences between comparison groups. Blood from healthy volunteers (N = 12) was collected at three time points. The miRNAs were extracted by a method predetermined to give the highest miRNA yield. Nine different miRNAs were quantified using different qPCR assays and analyzed using mixed models to identify sources of variability. A larger number of miRNAs from a publicly available blood miRNA microarray dataset with repeated measures were used for a bootstrapping procedure to investigate effects of repeated measures on power to detect fold changes in miRNA expression for a theoretical case-control study. Technical variability in qPCR replicates was identified as a significant source of variability (P power to detect small fold changes in blood miRNAs can be improved by accounting for sources of variability using repeated measures and choosing appropriate methods to minimize variability in miRNA quantification. This study demonstrates the importance of including repeated measures in experimental designs for blood miRNA research.

    Background Coronory heart disease (CHD) is a common medical problem worldwide that demands shared care of general practitioners and cardiologists for concerned patients. In order to improve the cooperation between both medical specialists and to optimize evidence-based care, a treatment pathway for patients with CHD was developed and evaluated in a feasibility study according to the recommendation for the development and evaluation of complex interventions of the British Medical Research Council (MRC). In the context of this feasibility study the objective of the present research was to investigate the contributions of different disease related (e.g. prior myocardial infarction), pathway related (e.g. basic medication) and demographic variables on patients` perceived health related quality of life (HRQoL) as a relevant and widely used outcome measure in cardiac populations. Methods Data assessing demographic, disease and pathway related variables of CHD patients included in the study were collected in a quasi-experimental design with three study arms (pathway developers, users, control group) via case record forms and questionnaires at baseline and after 6 and 12 (intervention groups), and 9 months (control group), respectively after the initial implementation on GP level. Additionally, at the same measuring points the CHD patients participating in the study were interviewed by phone regarding their perceived HRQoL, measured with the EuroQol EQ-5D as an index-based health questionnaire. Due to the hierarchical structure of the data, we performed cross-sectional and longitudinal linear mixed models to investigate the impact of disease related, pathway related and demographic variables on patients` perceived HRQoL.

    In larger oral health surveys, clinical measurements are often obtained using several examiners. This raises the issue of inter-observer variability in measurement. Often, the problem is dealt with by reporting kappa values obtained in a calibration exercise. In the present study, the limitations of this statistic are presented, and an alternative, based on a Bayesian approach, is proposed. When the alternative approach was applied to caries experience data obtained in an oral health screening survey in seven-year-old Flemish children (Signal Tandmobiel study), it could be ruled out that the observed geographic East-West gradient was due to bias induced by variability in scoring of the different dental examiners involved. The proposed method offers an opportunity to refine existing analytical approaches and is relevant to any health outcome study.

    Full Text Available Helicobacter pylori and latent toxoplasmosis are widespread diseases that have been associated with cognitive deficits and Alzheimer's disease. We sought to determine whether interactions between Helicobacter pylori and latent toxoplasmosis, age, race-ethnicity, educational attainment, economic status, and general health predict cognitive function in young and middle-aged adults. To do so, we used multivariable regression and multivariate models to analyze data obtained from the United States' National Health and Nutrition Examination Survey from the Centers for Disease Control and Prevention, which can be weighted to represent the US population. In this sample, we found that 31.6 percent of women and 36.2 percent of men of the overall sample had IgG Antibodies against Helicobacter pylori, although the seroprevalence of Helicobacter pylori varied with sociodemographic variables. There were no main effects for Helicobacter pylori or latent toxoplasmosis for any of the cognitive measures in models adjusting for age, sex, race-ethnicity, educational attainment, economic standing, and self-rated health predicting cognitive function. However, interactions between Helicobacter pylori and race-ethnicity, educational attainment, latent toxoplasmosis in the fully adjusted models predicted cognitive function. People seropositive for both Helicobacter pylori and latent toxoplasmosis - both of which appear to be common in the general population - appear to be more susceptible to cognitive deficits than are people seropositive for either Helicobacter pylori and or latent toxoplasmosis alone, suggesting a synergistic effect between these two infectious diseases on cognition in young to middle-aged adults.

    The purpose of this study was to examine the degrees of cellular phone usage among middle school students and to identify discriminating factors of addictive use of cellular phones among sociodemographic and psychological variables. From 123 middle schools in Busan, potential participants were identified through stratified random sampling and 747 middle school students participated in the study. The data was collected from December 1, 2004 to December 30, 2004. Descriptive and discriminant analyses were used. Fifty seven percent of the participants were male and 89.7% used cellular phones at school. The participants were grouped into three groups depending on the levels of the cellular phone usage: addicted (n=117), dependent (n=418), non-addicted (n=212). Within the three groups, two functions were produced and only one function was significant, discriminating the addiction group from non-addiction group. Additional discriminant analysis with only two groups produced one function that classified 81.2% of the participants correctly into the two groups. Impulsiveness, anxiety, and stress were significant discriminating factors. Based on the findings of this study, developing intervention programs focusing on impulsiveness, anxiety and stress to reduce the possible addictive use of cellular phones is suggested.

    Periodontal disease is the most common cause of tooth loss. It is has insidious onset, chronic course, and commonly result due to cumulative effect of dietary habits, oral hygiene methods and oral habits practiced over the years. This study was planned to evaluate the periodontal health status of elderly population (above 60 years) in the community, using CPITN index, gingival recession, mobility of teeth and halitosis, using modified WHO Oral Health Survey Proforma. In addition, impact of several socio-demographic variables, oral hygiene practices, oral habits, chronic systemic diseases, dietary preferences and body mass index (BMI) on periodontal health status was also studied. It was found that prevalence of periodontal diseases in the elderly was high. Step-wise multivariate logistic regression analysis showed that periodontal diseases were directly correlated with age, oral hygiene practices and presence of cardiac diseases.

    Religion is a powerful coping strategy. Diabetes and depression are common conditions in our environment that induce psychological distress, thus requiring coping for better outcome. Studies indicate that increased religiosity is associated with better outcome in clinical and general populations. Therefore, studies of the distribution of religiosity and religious coping among these populations are essential to improve outcome. To assess the association between religiosity, religious coping in depression and diabetes mellitus, and selected sociodemographic variables (age, gender and occupational status). Using simple random sampling we recruited 112 participants with diabetes and an equal number with depression consecutively, matching for gender. Religiosity was determined using religious orientation scale (revised), religious coping with brief religious coping scale and socio-demographic variables with a socio-demographic questionnaire. Intrinsic religiosity was greater among older people with depression than among older people with diabetes(t=5.02,p<0.001); no significant difference among young people with depression and diabetes(t=1.47,p=0.15).Positive religious coping was greater among older people with depression than among older people with diabetes(t=2.31,p=0.02); no difference among young people with depression and diabetes(t=0.80,p=0.43). Females with depression had higher intrinsic religiosity scores than males with depression(t=3.85,p<0.001); no difference in intrinsic religiosity between females and males with diabetes(t=0.99,p=0.32).Positive religious coping was greater among participants with diabetes in the low occupational status(t=2.96,p<0.001) than those in the high occupational status. Religion is indeed a reliable coping method, most commonly used by the elderly and females with depression. Positive religious coping is more common among diabetic patients who are in the low occupational status.

    Full Text Available This study carries out a parametrical analysis of the seismic response to asynchronous earthquake ground motion of a long multispan rc bridge, the Fener bridge, located on a high seismicity area in the north-east of Italy. A parametrical analysis has been performed investigating the influence of the seismic input correlation level on the structural response: a series of nonlinear time history analyses have been executed, in which the variation of the frequency content in the accelerograms at the pier bases has been described by considering the power spectral density function (PSD and the coherency function (CF. In order to include the effects due to the main nonlinear behaviours of the bridge components, a 3D finite element model has been developed, in which the pounding of decks at cap-beams, the friction of beams at bearings, and the hysteretic behaviour of piers have been accounted for. The sensitivity analysis has shown that the asynchronism of ground motion greatly influences pounding forces and deck-pier differential displacements, and these effects have to be accurately taken into account for the design and the vulnerability assessment of long multispan simply supported bridges.

    considered. The results showed that the total V95 obtained for the entire course of the treatment was similar to the one obtained for the planning CT, which shows that interfractional variability was successfully compensated. For 4 patients out of 9, V95 > 95% was thus obtained for both the planning CT and the total dose target coverage. For the rest of the cohort, a slight modification of the contours or dose reduction should permit to obtain a better clinical treatment plan that could be delivered over the course of the treatment. In the presented study, intrafractional motion occuring during the treatment of lung tumors was efficiently mitigated using optimized treatment planning parameters and gating, while interfractional variability showed the largest impact on dose delivery. Nevertheless, this variability was efficiently mitigated, as shown by target dose coverage obtained at the end of the treatment which was very close to the one obtained for the planning CT.

    Quality of life (QoL) has presently a firmly established position as an important endpoint in medical care. Multiple sclerosis (MS) is a chronic neurological disease with considerable effect on patients' QoL. QoL of MS patients from many European countries has already been assessed but little is known on health-related QoL of Polish subjects with MS. Few studies have taken into consideration multiple predictors of QoL. The aim of this study was to elicit the most relevant factors that determine QoL of Polish group of MS patients. Socio-demographic and clinical factors as well as the influence of disability level were analyzed in this study. 173 MS patients and 86 healthy controls underwent assessment using the Mini Mental Status Examination, WHOQOL-100, Beck Depression Inventory and Fatigue Severity Scale. Data were analyzed by a stepwise linear regression analysis. MS patients had significantly worse global QoL and worse QoL in physical and psychological health domains, lower level of independence, worse social relations and were less satisfied with the surrounding environment they lived in compared with healthy controls (pMS subjects had also higher level of depression and fatigue compared to healthy controls (pQoL of Polish MS patients were depression, disability level and fatigue.

    Full Text Available E-learning as an educational approach has been adopted by diverse educational and academic centers worldwide as it facilitates learning in facing the challenges of the new era in education. Considering the significance of virtual education and its growing practice, it is of vital importance to examine its components for promoting and maintaining success. This analytical cross-sectional study was an attempt to determine the relationship between four factors of content, educator, learner and system, and effective e-learning in terms of demographic variables, including age, gender, educational background, and marital status of postgraduate master's students (MSc studying at virtual faculty of Tehran University of Medical Sciences. The sample was selected by census (n=60; a demographic data gathering tool and a researcher-made questionnaire were used to collect data. The face and content validity of both tools were confirmed and the results were analyzed by descriptive statistics (frequency, percentile, standard deviation and mean and inferential statistics (independent t-test, Scheffe's test, one-way ANOVA and Pearson correlation test by using SPSS (V.16. The present study revealed that There was no statistically significant relationship between age and marital status and effective e-learning (P>0.05; whereas, there was a statistically significant difference between gender and educational background with effective e-learning (P<0.05. Knowing the extent to which these factors can influence effective e-learning can help managers and designers to make the right decisions about educational components of e-learning, i.e. content, educator, system and learner and improve them to create a more productive learning environment for learners.

    The aim of this study is to determine which cancer and demographic criteria influence the indication for surgery (radical prostatectomy) or radiation therapy (external or brachytherapy) in the treatment of prostate cancer. An analysis of the 2714 patients of the 2010 National Prostate Cancer Registry treated with curative intent. The analysed variables were age, prostate-specific antigen (PSA), prostate volume, the number of biopsy cores, the percentage of positive cores, the stage, Gleason score, the type of pathologist, the presence of perineural invasion and the study centre. We analysed the association among these variables and the type of treatment (surgery vs. radiation therapy/brachytherapy), using a univariate analysis (Student's t test and chi-squared) and a binary multiple logistic regression. The 48.12% of the patients (1306/2714) were treated with surgery, and 51.88% (1,408/2,714) underwent radiation therapy/brachytherapy. Differences were observed between the patients treated with prostatectomy and those treated with radiation therapy/brachytherapy (p<.05) in age (63.50±6.5 vs. 69.0±6.7), PSA (8.76±16.97 vs. 13.21±15.88), biopsied cores, percentage of positives cores (30.0±22 vs. 38.7±29), Gleason score (G6: 53.9% vs. 46.1%; G7: 45% vs. 55% G8-10: 26.6%, 73.4%), stage (localised: 50% vs. 50%; locally advanced: 14.6% vs. 85.4%), perineural invasion and hospital centre. In the multivariate analysis, the selected independent variables were age, PSA, percentage of positives cores, stage, Gleason score and hospital centre. According to our study, age, tumour aggressiveness and stage and the centre where the patient will be treated affect the selection of curative treatment for prostate cancer. Copyright © 2016 AEU.

    To study the associations between nutrient intake, dairy intake and socioeconomic variables. Food consumption data using 24 h recall were collected in 3600 children, aged 0.5 to 12 years old in addition to frequency of dairy use and anthropometric and sociodemographic variables. Overall height for age Z-score (HAZ) and body mass index for age Z-score (BAZ) values (mean±SE) were -1.40±0.03 and -0.48±0.03 respectively, associated with a high prevalence of stunting and thinness in the population. The overall percentage of children not using any dairy products was 71%, and this percentage increased steadily with age. The overall energy intake from dairy was 99±3 kcal/capita/day and the overall energy intake from dairy in dairy users was 291±7 kcal/day. Dairy use did not differ between boys and girls, but was higher in urban areas, higher if the education of the mother was higher and higher if the mother had a permanent job and if the wealth status of the family was in the upper levels. Nutrient intake after the age of 3 years was inadequate for energy and all nutrients except for protein. The achievement of Recommended Dietary Allowances (RDA) for all nutrients was higher in dairy users compared to non-dairy users, also after correcting for the confounding effect of the higher energy intake (from dairy) and socio-demographic variables. The contribution increased with increasing frequency of dairy use. Adequate dairy intake can substantially add to the achievement of RDA in Indonesian children.

    Spatial patterns of snow accumulation and melt control water and nutrient fluxes from mountain landscapes and determine the dynamics of resource availability for nearby human and ecological communities. Because seasonal snowpack is sensitive to changes in regional climate, there is a growing need for a snowpack classification system that (1) recognizes salient processes, (2) captures the variance of the system, (3) recognizes temporal and/or spatial change, and (4) has application to predicting snowmelt runoff regimes. Previous classification systems have focused on textural and stratigraphic snow characteristics or climatological observations to map broad geographic classes (e.g. maritime, continental, ephemeral, etc.). While these approaches have revealed general patterns, they may not capture the spatial heterogeneity of snowpack characteristics that are common across high relief terrain. Here, we use 1 km resolution gridded outputs from a physically based, spatially-distributed energy- and mass-balance snow model (SNODAS) to produce a snow classification system for the western U.S. and Great Plains. To meet the outlined criterion, we initially explored the ability of a large number of metrics (13) to characterize the amount, timing, and melt-rate of snowpack. Principal components analysis and pairwise correlations were used to identify a subset of metrics (6) that captured the variance of the system but also contributed unique information. K-means was used to delineate 12 process-based groups that reveal both climatic and orographic influences on snowpack accumulation, timing, and melt rate. The important effects of elevation-mediated processes in our classification system suggest a greater spatial diversity in snowpack patterns than suggested by previous characterizations (e.g. maritime-to-continental). Application of the system from the early 2000's to present reveals that interannual temporal and spatial variability have been greatest in the Columbia Plateau

Materials and Methods: A cross-sectional school-based study was performed on 500 school children (aged 7-14 years for the duration of 1 year. Potential triggering and aggravating demographic and social variables were investigated based on a diagnosis of International Classification of Headache Disorder-II headache. Results: The prevalence of recurrent headache was found to be 25.5% in Indore. Of the studied population, 15.5% had migraine, 5% had tension-type headache migraine, and 5% had mixed-type headache symptoms suggesting both of above. Overall headaches were found to be more common among girls, but tension-type was more common in boys. Using regression analysis, we found that sensitive personality traits (especially vulnerable children, increasing age, female gender and family history of headache had a statistically significant effect on headaches in children. In addition, mathematic or science test dates and post weekend days in school were found to increase the occurrence of headache in school-going children. Hobbies were found to have a significant effects on headaches. Conclusion: As a common healthcare problem, headache is prevalent among school children. Various sociodemographic factors are known to trigger or aggravate primary headache disorders of school children. Lifestyle-coping strategies are essential for school children.

    A holistic perspective on health implies giving careful consideration to the relationship between physical and mental health. In this regard the present study sought to determine the level of Positive Mental Health (PMH) among people with chronic physical health problems, and to examine the relationship between the observed levels of PMH and both physical health status and socio-demographic variables. The study was based on the Multifactor Model of Positive Mental Health (Lluch, 1999), which comprises six factors: Personal Satisfaction (F1), Prosocial Attitude (F2), Self-control (F3), Autonomy (F4), Problem-solving and Self-actualization (F5), and Interpersonal Relationship Skills (F6). The sample comprised 259 adults with chronic physical health problems who were recruited through a primary care center in the province of Barcelona (Spain). Positive mental health was assessed by means of the Positive Mental Health Questionnaire (Lluch, 1999). Levels of PMH differed, either on the global scale or on specific factors, in relation to the following variables: age: global PMH scores decreased with age (r=-0.129; p=0.038); b) gender: men scored higher on F1 (t=2.203; p=0.028) and F4 (t=3.182; p=0.002), while women scored higher on F2 (t -3.086; p=0.002) and F6 (t=-2.744; p=0.007); c) number of health conditions: the fewer the number of health problems the higher the PMH score on F5 (r=-0.146; p=0.019); d) daily medication: polymedication patients had lower PMH scores, both globally and on various factors; e) use of analgesics: occasional use of painkillers was associated with higher PMH scores on F1 (t=-2.811; p=0.006). There were no significant differences in global PMH scores according to the type of chronic health condition. The only significant difference in the analysis by factors was that patients with hypertension obtained lower PMH scores on the factor Autonomy (t=2.165; p=0.032). Most people with chronic physical health problems have medium or high levels of PMH

    Axial spondyloarthritis (ax-SpA) is a chronic inflammatory disease of the spine causing pain, stiffness, loss in physical function, and fatigue. Therefore, the physical and psychological burden of having this chronic disease can reduce the quality of life. We aimed to explore the relationship between demographic- and disease-related variables and health-related quality of life (HRQoL) in patients with ax-SpA. Demographic- and disease-related, HRQoL-related and treatment data were collected. Disease measures included the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), the BAS Functional Index (BASFI), the BAS Global (BAS-G) score, the Maastricht Ankylosing Spondylitis Enthesitis Score (MASES), the Health Assessment Questionnaire (HAQ) and co-morbidity. HRQoL was assessed using the SF-36 and the utility measures SF-6D and 15D. Variables associated with HRQoL were identified in unadjusted and adjusted analyses. We examined 380 patients with ax-SpA (67% men) with a mean age of 46 years. Among them, 86% reported exercising >1 h per week. Mean values were as follows: BASDAI, 3.17; MASES, 3.19; BASFI, 2.71; BAS-G. 3.88; and HAQ, 0.56. The percentage of current users of NSAIDs was 44%, and of DMARDs 23%. In multivariate analyses, exercising 1-3 h per week (B = 2.73, p = 0.022) and exercising >3 h per week (B = 2.71, p = 0.020), lower HAQ scores (B = -4.61, p = 0.001), lower BASFI scores (B = -1.05, p = 0.010) and lower BAS-G scores (B = -0.91, p = 0.001) were independently associated with higher SF-36-PCS scores, whereas modest alcohol consumption (B = 4.63, p = 0.018) and a lower BAS-G score (B = -1.73, p Exercising 1-3 h per week (B = 0.032, p = 0.004) and exercising >3 h per week (B = 0.036, p = 0.001), lower HAQ scores (B = -0.051, p exercising 1-3 h per week (B = 0.045, p = 0.001) and exercising > 3 h per week (B = 0.053, p < 0.001), lower HAQ scores (B = -0.054, p = 0.001) and lower BAS-G scores

    In order to replace traditional sampling and analysis techniques, turbidimeters can be used to estimate TSS concentration in sewers, by means of sensor and site specific empirical equations established by linear regression of on-site turbidity Tvalues with TSS concentrations C measured in corresponding samples. As the ordinary least-squares method is not able to account for measurement uncertainties in both T and C variables, an appropriate regression method is used to solve this difficulty and to evaluate correctly the uncertainty in TSS concentrations estimated from measured turbidity. The regression method is described, including detailed calculations of variances and covariance in the regression parameters. An example of application is given for a calibrated turbidimeter used in a combined sewer system, with data collected during three dry weather days. In order to show how the established regression could be used, an independent 24 hours long dry weather turbidity data series recorded at 2 min time interval is used, transformed into estimated TSS concentrations, and compared to TSS concentrations measured in samples. The comparison appears as satisfactory and suggests that turbidity measurements could replace traditional samples. Further developments, including wet weather periods and other types of sensors, are suggested.

    The human population displays high variation in taste perception. Differences in individual taste sensitivity may also impact on nutrient intake and overall appetite. A well-characterized example is the variable perception of bitter compounds such as 6-n-propylthiouracil (PROP) and phenylthiocarbamide (PTC), which can be accounted for at the molecular level by polymorphic variants in the specific type 2 taste receptor (TAS2R38). This phenotypic variation has been associated with influencing dietary preference and other behaviors, although the generalization of PROP/PTC taster status as a predictor of sensitivity to other tastes is controversial. Here, we proposed that the taste sensitivities of different bitter compounds would be correlated only when they activate the same bitter taste receptor. Thirty-four volunteers were exposed to 8 bitter compounds that were selected based on their potential to activate overlapping and distinct repertoires of TAS2Rs. Taste intensity ratings were evaluated using the general Labeled Magnitude Scale. Our data demonstrate a strong interaction between the intensity for bitter substances when they activate common TAS2Rs. Consequently, PROP/PTC sensitivity was not a reliable predictor of general bitter sensitivity. In addition, our findings provide a novel framework to predict taste sensitivity based on their specific T2R activation profile.

    There has been increasing research on posttraumatic stress disorder (PTSD) following childbirth in the last two decades. The literature on predictors of who develops posttraumatic stress symptoms (PSS) suggests that both vulnerability and birth factors have an influence, but many studies measure predictors and outcomes simultaneously. In this context, we aimed to examine indirect and direct effects of predictors of PSS, which were measured longitudinally. We assessed women within the first days (n=353), 6 weeks, and 12 months (n=183) after having given birth to a healthy infant. The first assessment included questions on demographics, pregnancy, and birth experience. The second and third assessments contained screenings for postpartum depression, PTSD, and general mental health problems, as well as assessing social support and physical well-being. We analysed our data using structural equation modelling techniques (n=277). Our final model showed good fit and was consistent with a diathesis-stress model of PSS. Women who had used antidepressant medication in the 10 years before childbirth had higher PSS at 6 weeks, independent of birth experiences. Subjective birth experience was the early predictor with the highest total effect on later PSS. Interestingly, a probable migration background also had a small but significant effect on PSS via more episiotomies. The null results for social support may have been caused by a ceiling effect. Given that we measured predictors at different time points, our results lend important support to the etiological model, namely, that there is a vulnerability pathway and a stress pathway leading to PSS. PSS and other psychological measures stayed very stable between 6 weeks and 1 year postpartum, indicating that it is possible to identify women developing problems early. Our results are consistent with a diathesis-stress model: vulnerability (antidepressant use in the previous 10 years) influenced posttraumatic stress symptoms at 6

    Intimate partner violence (IPV) is common among patients with severe mental illness such as schizophrenia. Few surveys have explored IPV among this specific group of patients and the demographic characteristics of victims in Nigeria. The aim of this survey was to explore socio-demographic, socioeconomic characteristics of victims and partners. A cross-sectional randomized survey of 79 women with schizophrenia from a major adult psychiatric outpatient in South-south Nigeria was done. The Structured Clinical Interview for DSM-IV (SCID) was used to establish the diagnosis of schizophrenia among the participants and a purposely designed questionnaire to assess IPV. The mean age of the participants was 38.3 ± 2.8 years; the majority (73%) reported at least one form of IPV. Verbal abuse was the most (71%) prevalent form of IPV. Our findings highlight a need for proper attention to demographics of both victims and their male partners by clinicians.

  9. Two models to compute an adjusted Green Vegetation Fraction taking into account the spatial variability of soil NDVI

    The green vegetation fraction (Fg) is an important climate and hydrologic model parameter. The commonly- used Fg model is a simple linear mixing of two NDVI end-members: bare soil NDVI (NDVIo) and full vegetation NDVI (NDVI∞). NDVI∞ is generally set as a percentile of the historical maximum NDVI for each land cover. This approach works well for areas where Fg reaches full cover (100%). Because many biomes do not reach Fg=0, however, NDVIo is often determined as a single invariant value for all land cover types. In general, it is selected among the lowest NDVI observed over bare or desert areas, yielding NDVIo close to zero. There are two issues with this approach: large-scale variability of soil NDVI is ignored and observations on a wide range of soils show that soil NDVI is often larger. Here we introduce and test two new approaches to compute Fg that takes into account the spatial variability of soil NDVI. The first approach uses a global soil NDVI database and time series of MODIS NDVI data over the conterminous United States to constrain possible soil NDVI values over each pixel. Fg is computed using a subset of the soils database that respects the linear mixing model condition NDVIo≤NDVIh, where NDVIh is the pixel historical minimum. The second approach uses an empirical soil NDVI model that combines information of soil organic matter content and texture to infer soil NDVI. The U.S. General Soil Map (STATSGO2) database is used as input for spatial soil properties. Using in situ measurements of soil NDVI from sites that span a range of land cover types, we test both models and compare their performance to the standard Fg model. We show that our models adjust the temporal Fg estimates by 40-90% depending on the land cover type and amplitude of the seasonal NDVI signal. Using MODIS NDVI and soil maps over the conterminous U.S., we also study the spatial distribution of Fg adjustments in February and June 2008. We show that the standard Fg method

    1979-11-01

    Relationships of four demographic variables and five affective variables to eight attributes of low back pain were investigated in 251 patients by stepwise, multivariate analysis. The demographic variables are age, sex, race, and education. The affective variables are state anxiety, trait anxiety anxiety, hostility, and depression. Seven of the pain variables are from the factorially derived Low Back Pain Questionnaire. The eighth pain variable is a self-estimate of intensity. Relationships among demographic and pain variables are small and unsystematic. Hostility has a small, systematically inverse relation to pain variables, supporting theories relating low back pain to inhibition of anger. Anxiety has a small positive relationship, and depression has no relationship to pain variables. In general, the small relationships indicate that the Low Back Pain Questionnaire provides descriptions of pain that are not confounded by social characteristics or current emotional states of patients.

    Full Text Available Background: Platinum based doublets chemotherapy are the standard of care for metastatic or advanced non-small cell lung carcinoma. This leads to modest survival advantage and improve quality-of-life. However, patients with advanced or metastatic disease eventually present disease progression and needs second-line systemic therapy in a selected group of patients or other supportive measures. There is very little knowledge available from the literature about the prognostic variables in patients, who receive second-line therapy. Materials and Methods: We retrospectively reviewed 329 patients received second-line treatment from July 2007 to September 2011 in the Department of Radiation Oncology, Burdwan Medical College and Hospital. For statistical analysis, 12 potential prognostic variables included. Univariate and multivariate regression analysis carried out to identify the prognostic variables associated with survival. Results: The results of univariate analysis for overall survival (OS and survival after second-line therapy identified to have prognostic significance: Age, sex, performance status, smoking history, serum lactate dehydrogenase, histopathology, first-line chemotherapy and its response and second-line therapy except the stage at diagnosis and site of failure after first-line therapy. The multivariate Cox regression analysis has shown that only performance and second-line therapy were independent prognostic variables for survival after second-line treatment and above these prognostic factors; age, smoking status and progression free survival also for OS. Conclusion: The performance status has shown consistent result as a prognostic factor in univariate and multivariate analysis for OS and survival after second-line therapy. These findings may also facilitate pretreatment prediction of survival and be used for selecting patients for the correct choice of cytotoxic therapy.

    Full Text Available The goal of this study was to further the understanding of complex processes that are the base for feelings and satisfaction judgments by examining two models of subjective well-being. 1048 participants rated satisfaction with life and filled out IPIP-50 questionnaire that measures personality traits of the Big five model and demographic data questionnaire. Satisfaction with life in general was statistically significantly positively correlated with satisfaction of relationships with other people, satisfaction with health as well as with specific aspects of these domains. As was expected according to judgment model, correlations were higher for global domains than for specific aspects of satisfaction except for satisfaction with mood. Hypothesis of general positivity model and judgment model were tested in a series of hierarchical regression analyses. General life satisfaction explained variance of both global domains above and beyond satisfaction with corresponding specific domains. Contribution of global life satisfaction was significant even after effect of big five personality traits was controlled. Personality traits of the Big five model were statistically significantly associated with general life satisfaction. Correlation coefficients were -0.41 for Neuroticism, 0.30 for Extraversion, 0.14 for Agreeableness, 0.13 for Conscientiousness and 0.22 for Intellect. Age, education and being in a relationship were positively correlated with general life satisfaction. In this connection younger, better educated persons and those being in relationship were more satisfied with life in general. Women had higher levels of satisfaction for relationship with parents, while men had higher levels of satisfaction with partner, mobility, energy level, immunity and absence of pain.

    A novel electrical circuit analogy is proposed modelling electrochemical systems under realistic automotive operation conditions. The model is developed for a lithium ion battery and is based on a pseudo 2D electrochemical model. Although cast in the framework familiar to application engineers, the model is essentially an electrochemical battery model: all variables have a direct physical interpretation and there is direct access to all states of the cell via the model variables (concentrations, potentials) for monitoring and control systems design. This is the first Equivalent Circuit Network -type model that tracks directly the evolution of species inside the cell. It accounts for complex electrochemical phenomena that are usually omitted in online battery performance predictors such as variable double layer capacitance, the full current-overpotential relation and overpotentials due to mass transport limitations. The coupled electrochemical and thermal model accounts for capacity fade via a loss in active species and for power fade via an increase in resistive solid electrolyte passivation layers at both electrodes. The model's capability to simulate cell behaviour under dynamic events is validated against test procedures, such as standard battery testing load cycles for current rates up to 20 C, as well as realistic automotive drive cycle loads.

  4. Growth parameters of Penicillium expansum calculated from mixed inocula as an alternative to account for intraspecies variability.

    2014-09-01

    The aim of this work was to compare the radial growth rate (μ) and the lag time (λ) for growth of 25 isolates of Penicillium expansum at 1 and 20 ºC with those of the mixed inoculum of the 25 isolates. Moreover, the evolution of probability of growth through time was also compared for the single strains and mixed inoculum. Working with a mixed inoculum would require less work, time and consumables than if a range of single strains has to be used in order to represent a given species. Suitable predictive models developed for a given species should represent as much as possible the behavior of all strains belonging to this species. The results suggested, on one hand, that the predictions based on growth parameters calculated on the basis of mixed inocula may not accurately predict the behavior of all possible strains but may represent a percentage of them, and the median/mean values of μ and λ obtained by the 25 strains may be substituted by the value obtained with the mixed inoculum. Moreover, the predictions may be biased, in particular, the predictions of λ which may be underestimated (fail-safe). Moreover, the prediction of time for a given probability of growth through a mixed inoculum may not be accurate for all single inocula, but it may represent 92% and 60% of them at 20 and 1 ºC, respectively, and also their overall mean and median values. In conclusion, mixed inoculum could be a good alternative to estimate the mean or median values of high number of isolates, but not to account for those strains with marginal behavior. In particular, estimation of radial growth rate, and time for 0.10 and 0.50 probability of growth using a cocktail inoculum accounted for the estimates of most single isolates tested. For the particular case of probability models, this is an interesting result as for practical applications in the food industry the estimation of t10 or lower probability may be required.

    Interventions to increase cooking skills (CS) and food skills (FS) as a route to improving overall diet are popular within public health. This study tested a comprehensive model of diet quality by assessing the influence of socio-demographic, knowledge- and psychological-related variables alongside perceived CS and FS abilities. The correspondence of two measures of diet quality further validated the Eating Choices Index (ECI) for use in quantitative research. A cross-sectional survey was conducted in a quota-controlled nationally representative sample of 1049 adults aged 20-60 years drawn from the Island of Ireland. Surveys were administered in participants' homes via computer-assisted personal interviewing (CAPI) assessing a range of socio-demographic, knowledge- and psychological-related variables alongside perceived CS and FS abilities. Regression models were used to model factors influencing diet quality. Correspondence between 2 measures of diet quality was assessed using chi-square and Pearson correlations. ECI score was significantly negatively correlated with DINE Fat intake (r = -0.24, p socio-demographic, knowledge, psychological variables and CS and FS abilities on dietary outcomes varied, with regression models explaining 10-20 % of diet quality variance. CS ability exerted the strongest relationship with saturated fat intake (β = -0.296, p food choices (ECI) (β = 0.04, p > 0.05). Greater CS and FS abilities may not lead directly to healthier dietary choices given the myriad of other factors implicated; however, CS appear to have differential influences on aspects of the diet, most notably in relation to lowering saturated fat intake. Findings suggest that CS and FS should not be singular targets of interventions designed to improve diet; but targeting specific sub-groups of the population e.g. males, younger adults, those with limited education might be more fruitful.

In this study, validity of information obtained by questionnaire in the screening for Schistosoma mansoni infection was assessed in four communities in the State of Minas Gerais, Brazil. Explanatory variables were water contact activities, sociodemographic characteristics and previous treatment for schistosomiasis. From 677, 1474, 766 and 3290 individuals eligible for stool examination in the communities, 89 to 97% participated in the study. The estimated probability of individuals to be infected, if they have all characteristics identified as independently associated with S.mansoni infection, varied from 15% in Canabrava, to 42% in Belo Horizonte, 48% in Comercinho and 80% in São José do Acácio. Our results do not support the hypothesis that a same questionnaire on risk factors could be used in screening for S.mansoni infection in different communities.

  7. Testing a Model of the Relationship of Demographic, Affective, and Fitness Variables to Academic Achievement among Non-Science Majors at an Independent University

    Dutra, Andrew Martin

    The purpose of this study was to determine the relationship of specific attributes of college students to their academic achievement at an independent university in central Florida. Academic achievement was measured as the numeric score on the final exam in a survey-of-science course (EDS 1032) required for non-science majors. Attribute sets included personological, affective, and fitness variables. A hypothesized diagram of the direct and indirect effects among these attributes relative to academic achievement was developed and tested using data collected Spring 2014 from 168 students in four sections of EDS 1032 at Florida Institute of Technology. Multiple regression results revealed that 19% of the variance in a students' academic achievement was due to the influence of these three sets of research factors; this was found to be statistically significant. The results of mediation analyses also indicated that three variables had significant direct effects on academic achievement, namely gender, number of academic credits, and sports motivation. In addition, gender had a significant indirect effect on academic achievement via stress, and the number of academic credits had a significant indirect effect on academic achievement via sports motivation. These findings indicated that female students scored roughly six points higher than male students on this final exam. Also, gender's influence on academic achievement was partially attributable to the student's level of stress (e.g., male students with high levels of stress had lower grades on this final exam than female students with the same level of stress). In addition, it was found that students taking more academic credits were likely to score higher on this final exam than those students taking fewer credits. Further, as students' level of sports amotivation increased, the strength of the relationship between the number of student academic credits and academic achievement decreased. These results support Self

  8. Refining regional SOC estimates: Accounting for erosion induced within field variability of the vertical distribution of SOC.

    2013-04-01

    Recently, soil organic carbon (SOC) is considered as a dynamic soil property largely influencing soil quality and global C-cycling. Consequently, accurate mapping of SOC at the regional or national scale becomes an important issue in order to help policymakers in developing an appropriate soil and climate change management strategy. So far, in these studies, only factors determining the spatial and temporal distribution of SOC at the landscape scale, such as soil type, land use (change), climate and agro-management, were considered. Despite the fact that a few recent studies incorporated as well the distribution of SOC with depth, resulting in an improved representation of the 3D distribution of SOC, most studies only considers topsoil and/or are characterized by simple sampling by site at rather coarse resolution. Consequently, they omit quantification of stable subsoil carbon buried in depositional areas and does not allow to clearly identify significant differences of SOC and erosion at the within field scale. Hence, the variability of SOC at smaller scales in complex terrain driven by lateral soil transport processes (such as soil erosion), is still rather understudied and is not (well) presented in existing regional SOC estimates. Nevertheless, incorporating this smaller level of spatial detail will most probably have a major influence on SOC mapping and regional SOC stock dynamics' calculations. Consequently, there exists an urgent need in conducting an appropriate soil sampling strategy considering deeper layers and enabling us to detect significant patterns at detailed spatial levels. In this study we aim to unravel the variation of SOC depth distributions along typical hillslope transects under cropland (Devon, UK) and link these to soil redistribution rates and variations in C input, i.e. below and above ground biomass productivity. The radionuclide isotope Caesium-137 (137Cs) was used as proxy for erosion. Furthermore, a soil sampling strategy was

    2016-07-01

    Full Text Available Conventional analysis of functional magnetic resonance imaging (fMRI data using the general linear model (GLM employs a neural model convolved with a canonical hemodynamic response function (HRF peaking 5s after stimulation. Incorporation of a further basis function, namely the canonical HRF temporal derivative, accounts for delays in the hemodynamic response to neural activity. A population that may benefit from this flexible approach is children whose hemodynamic response is not yet mature. Here, we examined the effects of using the set based on the canonical HRF plus its temporal derivative on both first- and second-level GLM analyses, through simulations and using developmental data (an fMRI dataset on proprioceptive mapping in children and adults. Simulations of delayed fMRI first-level data emphasized the benefit of carrying forward to the second-level a derivative boost that combines derivative and nonderivative beta estimates. In the experimental data, second-level analysis using a paired t-test showed increased mean amplitude estimate (i.e., increased group contrast mean in several brain regions related to proprioceptive processing when using the derivative boost compared to using only the nonderivative term. This was true especially in children. However, carrying forward to the second-level the individual derivative boosts had adverse consequences on random-effects analysis that implemented one-sample t-test, yielding increased between-subject variance, thus affecting group-level statistic. Boosted data also presented a lower level of smoothness that had implication for the detection of group average activation. Imposing soft constraints on the derivative boost by limiting the time-to-peak range of the modelled response within a specified range (i.e., 4-6s mitigated these issues. These findings support the notion that there are pros and cons to using the informed basis set with developmental data.

    Conventional analysis of functional magnetic resonance imaging (fMRI) data using the general linear model (GLM) employs a neural model convolved with a canonical hemodynamic response function (HRF) peaking 5 s after stimulation. Incorporation of a further basis function, namely the canonical HRF temporal derivative, accounts for delays in the hemodynamic response to neural activity. A population that may benefit from this flexible approach is children whose hemodynamic response is not yet mature. Here, we examined the effects of using the set based on the canonical HRF plus its temporal derivative on both first- and second-level GLM analyses, through simulations and using developmental data (an fMRI dataset on proprioceptive mapping in children and adults). Simulations of delayed fMRI first-level data emphasized the benefit of carrying forward to the second-level a derivative boost that combines derivative and nonderivative beta estimates. In the experimental data, second-level analysis using a paired t-test showed increased mean amplitude estimate (i.e., increased group contrast mean) in several brain regions related to proprioceptive processing when using the derivative boost compared to using only the nonderivative term. This was true especially in children. However, carrying forward to the second-level the individual derivative boosts had adverse consequences on random-effects analysis that implemented one-sample t-test, yielding increased between-subject variance, thus affecting group-level statistic. Boosted data also presented a lower level of smoothness that had implication for the detection of group average activation. Imposing soft constraints on the derivative boost by limiting the time-to-peak range of the modeled response within a specified range (i.e., 4-6 s) mitigated these issues.

    Full Text Available A novel approach for a Poisson cluster stochastic rainfall generator was validated in its ability to reproduce important rainfall and watershed response characteristics at 104 locations in the United States. The suggested novel approach, The Hybrid Model (THM, as compared to the traditional Poisson cluster rainfall modeling approaches, has an additional capability to account for the interannual variability of rainfall statistics. THM and a traditional approach of Poisson cluster rainfall model (modified Bartlett-Lewis rectangular pulse model were compared in their ability to reproduce the characteristics of extreme rainfall and watershed response variables such as runoff and peak flow. The results of the comparison indicate that THM generally outperforms the traditional approach in reproducing the distributions of peak rainfall, peak flow, and runoff volume. In addition, THM significantly outperformed the traditional approach in reproducing extreme rainfall by 2.3% to 66% and extreme flow values by 32% to 71%.

    HIV-1 set-point viral load-the approximately stable value of viraemia in the first years of chronic infection-is a strong predictor of clinical outcome and is highly variable across infected individuals. To better understand HIV-1 pathogenesis and the evolution of the viral population, we must quantify the heritability of set-point viral load, which is the fraction of variation in this phenotype attributable to viral genetic variation. However, current estimates of heritability vary widely, from 6% to 59%. Here we used a dataset of 2,028 seroconverters infected between 1985 and 2013 from 5 European countries (Belgium, Switzerland, France, the Netherlands and the United Kingdom) and estimated the heritability of set-point viral load at 31% (CI 15%-43%). Specifically, heritability was measured using models of character evolution describing how viral load evolves on the phylogeny of whole-genome viral sequences. In contrast to previous studies, (i) we measured viral loads using standardized assays on a sample collected in a strict time window of 6 to 24 months after infection, from which the viral genome was also sequenced; (ii) we compared 2 models of character evolution, the classical "Brownian motion" model and another model ("Ornstein-Uhlenbeck") that includes stabilising selection on viral load; (iii) we controlled for covariates, including age and sex, which may inflate estimates of heritability; and (iv) we developed a goodness of fit test based on the correlation of viral loads in cherries of the phylogenetic tree, showing that both models of character evolution fit the data well. An overall heritability of 31% (CI 15%-43%) is consistent with other studies based on regression of viral load in donor-recipient pairs. Thus, about a third of variation in HIV-1 virulence is attributable to viral genetic variation.

    Full Text Available Cross-cultural studies on eating behaviors and relatedconstructs can identify cultural and social factorsthat contribute to eating disorder symptomatology.Eating disorders (EDs are a major cause for concernin the U.S., and recent studies in Colombia have showngrowing rates among their female population. In addition,cosmetic surgery procedures have been increasingrapidly in both the U.S. and Colombia, and preliminaryresearch suggests a positive relation between disorderedeating and endorsement of plastic surgery. In samplesof college women from Colombia and the U.S., we investigatedpatterns of association between disorderedeating variables and cosmetic surgery acceptance. Ourapproach utilized separate analyses for various subcomponentsof disordered eating (to determine their uniqueassociations with cosmetic surgery acceptance whileadjusting for potentially relevant covariates and examiningcross-cultural patterns. Participants were studentsat an urban, public college in the U.S. (n=163 and anurban, private college in Colombia (n=179. Overall,our findings suggested that participants from Colombiawith greater disordered eating were more likely to endorsecosmetic surgery for social reasons, while thosefrom the U.S. were more likely to consider undergoingcosmetic surgery for personal reasons. Differing findingsbetween the two samples may be due to cultural andsocial factors, which we delineate. These findings alsohave potential implications for presurgical counselingof cosmetic surgery candidates.

    This study assesses water stress by 2050 in river basins facing increasing human and climatic pressures, by comparing the impacts of various combinations of possible future socio-economic and climate trends. A modelling framework integrating human and hydro-climatic dynamics and accounting for interactions between resource and demand at a 10-day time step was developed and applied in two basins of different sizes and with contrasted water uses: the Herault (2500 km2, France) and the Ebro (85 000 km2, Spain) basins. Natural streamflow was evaluated using a conceptual hydrological model (GR4j). A demand-driven reservoir management model was designed to account for streamflow regulations from the main dams. Urban water demand was estimated from time series of population and monthly unit water consumption data. Agricultural water demand was computed from time series of irrigated area, crop and soil data, and climate forcing. Indicators comparing water supply to demand at strategic resource and demand nodes were computed. This framework was successfully calibrated and validated under non-stationary human and hydro-climatic conditions over the last 40 years before being applied under four combinations of climatic and water use scenarios to differentiate the impacts of climate- and human-induced changes on streamflow and water balance. Climate simulations from the CMIP5 exercise were used to generate 18 climate scenarios at the 2050 horizon. A baseline water use scenario for 2050 was designed based on demographic and local socio-economic trends. Results showed that projected water uses are not sustainable under climate change scenarios.

  18. Full likelihood analysis of genetic risk with variable age at onset disease--combining population-based registry data and demographic information.

    Directory of Open Access Journals (Sweden)

    Janne Pitkäniemi

    Full Text Available BACKGROUND: In genetic studies of rare complex diseases it is common to ascertain familial data from population based registries through all incident cases diagnosed during a pre-defined enrollment period. Such an ascertainment procedure is typically taken into account in the statistical analysis of the familial data by constructing either a retrospective or prospective likelihood expression, which conditions on the ascertainment event. Both of these approaches lead to a substantial loss of valuable data. METHODOLOGY AND FINDINGS: Here we consider instead the possibilities provided by a Bayesian approach to risk analysis, which also incorporates the ascertainment procedure and reference information concerning the genetic composition of the target population to the considered statistical model. Furthermore, the proposed Bayesian hierarchical survival model does not require the considered genotype or haplotype effects be expressed as functions of corresponding allelic effects. Our modeling strategy is illustrated by a risk analysis of type 1 diabetes mellitus (T1D in the Finnish population-based on the HLA-A, HLA-B and DRB1 human leucocyte antigen (HLA information available for both ascertained sibships and a large number of unrelated individuals from the Finnish bone marrow donor registry. The heterozygous genotype DR3/DR4 at the DRB1 locus was associated with the lowest predictive probability of T1D free survival to the age of 15, the estimate being 0.936 (0.926; 0.945 95% credible interval compared to the average population T1D free survival probability of 0.995. SIGNIFICANCE: The proposed statistical method can be modified to other population-based family data ascertained from a disease registry provided that the ascertainment process is well documented, and that external information concerning the sizes of birth cohorts and a suitable reference sample are available. We confirm the earlier findings from the same data concerning the HLA-DR3

    Full Text Available It is imperative for airport operators and airlines to have a clear understanding of the factors which influence the passenger’s decision with regard to which airport/airline combination to use in a multi-airport scenario. Interactions between demographic variables, such as gender and purpose of travel, and the choice attributes in the decision-making process exist. The extent to which specific attributes influence the passenger’s decision could be invaluable to service providers (airport operators and airlines in allocating and employing limited resources. The purpose of this article is to investigate the extent of the interactions between passenger demographics and attribute evaluation by taking into account the ordinal nature of the measurement scale.

  20. Enhancing the Variable Infiltration Capacity Model to Account for Natural and Anthropogenic Impacts on Evapotranspiration in the North American Monsoon Region

    Bohn, T. J.; Vivoni, E. R.

    2015-12-01

    Evapotranspiration (ET) is a poorly constrained flux in the North American monsoon (NAM) region, leading to potential errors in land-atmosphere feedbacks. Due to the region's arid to semi-arid climate, two factors play major roles in ET: sparse vegetation that exhibits dramatic seasonal greening, and irrigated agriculture. To more accurately characterize the spatio-temporal variations of ET in the NAM region, we used the Variable Infiltration Capacity (VIC) model, modified to account for soil evaporation (Esoil), irrigated agriculture, and the variability of land surface properties derived from the Moderate Resolution Imaging Spectroradiometer during 2000-2012. Simulated ET patterns were compared to field observations at fifty-nine eddy covariance towers, water balance estimates in nine basins, and six available gridded ET products. The modified VIC model performed well at eddy covariance towers representing the natural and agricultural land covers in the region. Simulations revealed that major source areas for ET were forested mountain areas during the summer season and irrigated croplands at peak times of growth in the winter and summer, accounting for 22% and 9% of the annual ET, respectively. Over the NAM region, Esoil was the largest component (60%) of annual ET, followed by plant transpiration (T, 32%) and evaporation of canopy interception (8%). Esoil and T displayed different relations with P in natural land covers, with Esoil tending to peak earlier than T by up to one month, while only a weak correlation between ET and P was found in irrigated croplands. These VIC-based estimates are the most realistic to date for this region, outperforming several other process-based and remote-sensing-based gridded ET products. Furthermore, spatio-temporal patterns reveal new information on the magnitudes, locations and timing of ET in the North American monsoon region, with implications for land-atmosphere feedbacks.

    Introduction More knowledge is warranted about multilevel ecological variables associated with context-specific sitting time among adolescents. The present study explored cross-sectional and longitudinal associations of ecological domains of sedentary behaviour, including socio-demographic, social-cognitive, health-related and physical-environmental variables with sitting during TV viewing, computer use, electronic gaming and motorized transport among adolescents. Methods For this longitudinal study, a sample of Belgian adolescents completed questionnaires at school on context-specific sitting time and associated ecological variables. At baseline, complete data were gathered from 513 adolescents (15.0±1.7 years). At one-year follow-up, complete data of 340 participants were available (retention rate: 66.3%). Multilevel linear regression analyses were conducted to explore cross-sectional correlates (baseline variables) and longitudinal predictors (change scores variables) of context-specific sitting time. Results Social-cognitive correlates/predictors were most frequently associated with context-specific sitting time. Longitudinal analyses revealed that increases over time in considering it pleasant to watch TV (p < .001), in perceiving TV watching as a way to relax (p < .05), in TV time of parents/care givers (p < .01) and in TV time of siblings (p < .001) were associated with more sitting during TV viewing at follow-up. Increases over time in considering it pleasant to use a computer in leisure time (p < .01) and in the computer time of siblings (p < .001) were associated with more sitting during computer use at follow-up. None of the changes in potential predictors were significantly related to changes in sitting during motorized transport or during electronic gaming. Conclusions Future intervention studies aiming to decrease TV viewing and computer use should acknowledge the importance of the behaviour of siblings and the pleasure adolescents experience during

    Full Text Available The aims of this article were to (a investigate whether practicing Tai Chi has an effect on stress, self-esteem, and perceived life expectancy and (b contrast a structural model of relation between the three latter variables taking into account age. One scale to assess stress, another scale to assess perceived life expectancy, and the 10-item Rosenberg’s Self-Esteem Scale were administrated to a nonprobability sample of 86 Tai Chi practitioners and 91 sedentary persons. Tai Chi practitioners had a lower level of stress, a greater self-esteem, and a greater perceived life expectancy than sedentary persons. Self-esteem had an effect on stress and perceived life expectancy, and stress had an effect on perceived life expectancy in both Tai Chi practitioners and sedentary persons. Age was correlated to self-esteem among sedentary persons, but not among Tai Chi practitioners. Age had a direct effect on perceived life expectancy among Tai Chi practitioners, but not among sedentary persons. It is concluded that Tai Chi practice has a beneficial effect on stress, perceived life expectancy, and self-esteem.

  10. Mortality-fertility synergies during the demographic transition in the developed world.

    Science.gov (United States)

    Sánchez-Barricarte, Jesús J

    2017-07-01

    The classic theory used to explain the demographic transition assumes that mortality is the key explanatory variable influencing the decline in fertility. However, the empirical results obtained in what is known as the Princeton European Fertility Project have led many specialists to question this assumption. Using both national and provincial aggregated data for 25 countries over a long time span, the analysis reported in this paper found that mortality does indeed play a fundamental role in accounting for the main demographic changes that occurred both before and during the transitional period. Others' research based on individual data has shown clearly that the number of surviving children was indeed an important factor for reproductive decisions. My analysis, using aggregated data, reached largely similar conclusions regarding the role of mortality in changing reproductive trends, via its impact on nuptiality and marital fertility at different stages of the demographic transition.

    Examinations of demographic and social factors associated with homophobia and fear of AIDS are limited by the frequent use of homogeneous, college student samples and limited examination of interrelationships among variables. The present study examined community attitudes toward homosexuality and fear of HIV/AIDS as a function of age, education, race/ethnicity, religious affiliation, political party affiliation, and personal contact with homosexual individuals and persons living with HIV/AIDS. A community sample of 463 adults completed standardized measures of homophobia and fear of AIDS as well as demographic and social background items. When examined separately, each demographic and social factor assessed, with the exception of race/ethnicity, was associated with homophobia and all but race/ethnicity and political party affiliation were associated with fear of AIDS. However, when entered into multiple regression analyses, 24% of the variance in homophobia was predicted by a single variable, including only personal contact with homosexual individuals, while 18% of the variance in fear of AIDS was accounted for by five variables, including personal contact with homosexual individuals, religious affiliation, political affiliation, education, and personal contact with someone living with HIV/AIDS. Findings suggest that it is important to consider intercorrelations among social and demographic factors, particularly when considering homophobia.

    This article examines the different characteristics of the many peoples inhabiting what used to be the Soviet Union and communist Eastern Europe, including Yugoslavia. The differences among these nationalities, or ethnic groups, are illustrated using the example of demographic modernization, showing how different peoples have or have not passed through the demographic transition process. The author looks at ethnic differences in mortality, fertility, natural increase, and migration, as well as economic and social inequalities among ethnic groups. The prospects for inter-ethnic conflict are assessed.

  15. Estimating TCR using an integrated model-observation framework that accounts for spatio-temporal variability and pre-industrial radiative imbalances.

    Apart from a few exceptions (e.g. Aldrin et al. 2012, Skeie et al. 2013) TCR estimates with EBMs are based on global data. Since these estimates don't represent the true spatial-temporal behaviour for observed temperature as well as external forcing (Marvel et al. 2015), we have developed a two-box EBM framework that accounts for these effects. In addition, external forcing from anthropogenic aerosol and GHGs tends to have different response times in comparison to volcanic stratospheric aerosols. Using PMIP3 and an extended ensemble of HadCM3 simulations (Euro500; Schurer et al. 2014) GCM simulations for the pre-industrial period, we obtain the fast and slow response time constants required in the EBM. With the most recent anthropogenic and natural forcing estimates, we test a range of TCR values against observations. The TCR/ECS ratio necessary to achieve that goal is taken from CMIP5 as observationally OHC-based estimates are notoriously unreliable. Given that observed and modelled OHC estimates are in agreement (Cheng et al. 2016), we argue that this should be the standard procedure the make inferences about ECS. Alternatively, it should be distinguished between equilibrium and effective climate sensitivity. The preliminary best estimate for TCR is 1.6K (1.1-2.2K) with an associated ECS value of 2.9K (2.0-4.0K). This is in good agreement with other D&A techniques that do use spatio-temporal patterns as well (e.g. Jones et al. 2016, Gillet et al. 2013). Correcting for natural ENSO variability and tas/tos-related inaccuracies (Richardson et al. 2016) further increases the robustness of the estimated sensitivity range. Our results also indicate that the small radiative imbalance caused by the period of very strong volcanic eruptions just before the CMIP5 historical period starts (1809-1840) has noteworthy implications for the response to later volcanic eruptions and the temperature evolution after 1850. Simply put, CMIP5-type simulations are slightly more sensitive

  16. Chronological objects in demographic research

    Full Text Available BACKGROUND Calendar time, age and duration are chronological objects. They represent an instant or a time period. Age and duration are usually expressed in units with varying lengths. The number of days in a month or a year depends on the position on the calendar. The units are also not homogeneous and the structure influences measurement. One solution, common in demography, is to use units that are large enough for the results not to be seriously affected by differences in length and structure. Another approach is to take the idiosyncrasy of calendars into account and to work directly with calendar dates. The technology that enables logical and arithmetic operations on dates is available. OBJECTIVE To illustrate logical and arithmetic operations on dates and conversions between time measurements. METHODS Software packages include utilities to process dates. I use existing and a few new utilities in R to illustrate operations on dates and conversions between calendar dates and elapsed time since a reference moment or a reference event. Three demographic applications are presented. The first is the impact of preferences for dates and days on demographic indicators. The second is event history analysis with time-varying covariates. The third is microsimulation of life histories in continuous time. CONCLUSIONS The technology exists to perform operations directly on dates, enabling more precise calculations of duration and elapsed time in demographic analysis. It eliminates the need for (a approximations and (b transformations of dates, such as Century Month Code, that are convenient for computing durations but are a barrier to interpretation. Operations on dates, such as the computation of age, should consider time units of varying length.

    Full Text Available Objective: the principal aim of the present study is to evaluate the influence of socio-demographic and clinical variables on health-related quality of life (HRQL in patients with inflammatory bowel disease. Patients and method: this was a cross-sectional study. health-related quality of life was measured with the Inflammatory Bowel Disease Questionnaire (IBDQ. A total of 120 patients, 60 with ulcerative colitis and 60 with Crohn's disease, participated in the study. Results: no significant differences were observed between ulcerative colitis and Crohn's disease patients in IBDQ dimensions. However, a multivariate analysis revealed that sex, type of treatment, extraintestinal symptoms, number of relapses in previous year, satisfaction with surgery, and need for psychological support were related to HRQL. Conclusions: the identification of these variables associated with HRQL in patients with inflammatory bowel disease shows them to be basically non-disease factors. Knowledge of such elements can turn out to be very useful in order to guide future research and modify specific factors in further interventions.Objetivo: el objetivo principal del presente trabajo consiste en evaluar la influencia de las variables sociodemográficas y clínicas en la calidad de vida relacionada con la salud de los pacientes con enfermedad inflamatoria intestinal.

    2011-09-01

    Full Text Available Abstract Background While the ultimate causes of most species extinctions are environmental, environmental constraints have various secondary consequences on evolutionary and ecological processes. The roles of demographic, genetic mechanisms and their interactions in limiting the viabilities of species or populations have stirred much debate and remain difficult to evaluate in the absence of demography-genetics conceptual and technical framework. Here, I computed projected times to metapopulation extinction using (1 a model focusing on the effects of species properties, habitat quality, quantity and temporal variability on the time to demographic extinction; (2 a genetic model focusing on the dynamics of the drift and inbreeding loads under the same species and habitat constraints; (3 a demo-genetic model accounting for demographic-genetic processes and feedbacks. Results Results indicate that a given population may have a high demographic, but low genetic viability or vice versa; and whether genetic or demographic aspects will be the most limiting to overall viability depends on the constraints faced by the species (e.g., reduction of habitat quantity or quality. As a consequence, depending on metapopulation or species characteristics, incorporating genetic considerations to demographically-based viability assessments may either moderately or severely reduce the persistence time. On the other hand, purely genetically-based estimates of species viability may either underestimate (by neglecting demo-genetic interactions or overestimate (by neglecting the demographic resilience true viability. Conclusion Unbiased assessments of the viabilities of species may only be obtained by identifying and considering the most limiting processes (i.e., demography or genetics, or, preferentially, by integrating them.

  7. Building demographic literacy.

    Science.gov (United States)

    Crews, K

    1993-01-01

    Students should get in the habit of seeking out the most current projections, estimates, or rates available. Since demographic measures change over time, publications based on the UN's world population projections from 1980 or 1990 may need to be supplemented using the UN's most current, 1992, projections. A 1989 Census Bureau report on the African American Population will not contain data from the 1990 Census or the 1992 Current Population Survey, conducted by the Census Bureau. Some groups collect data with advocacy in mind, as shown by the range of estimates of participants at the 1993 National March on Washington for Lesbian, Gay and Bi Equal Rights and Liberation. The organizers estimated that 1 million people participated; the US Park Police estimated 300,000; and the Washington Blade, a gay newspaper, reported 750,000. A seemingly innocuous choice of phrasing can change the meaning of demographic data. One commonly misreported concept is population doubling time which is not a prediction, but rather a concept designed to accent how fast a population is growing at the present time. At current rates, the population of India would double in size in 34 years, but it is more likely that growth rates will begin to slow down somewhat during that time. Older students may be encouraged to examine the assumptions behind population projections. The UN's long-range projection that world population will grow to 10 billion by 2050 is based on certain assumption about fertility and mortality during the period. With regard to the fastest growing US minority, Hispanics added the largest number of people to the US population during the 1980s, but Asians had the largest percent increase. The time to initiate demographic literacy is in the early grades of school.

    The study explores the potential clinical value of reading fluency measures in complementing demographic variables as indices of current intellectual capacity. IQ estimates (based on the PPVT-R, WASI Vocabulary and Block Design subtests) were obtained from a representative, non-clinical sample of 386 Greek adults aged 48–87 years along with two measures of reading efficiency (one involving relatively high-frequency words—WRE—and the second comprised of phonotactically matched pseudowords—PsWRE). Both reading measures (number of items read correctly in 45 s) accounted for significant portions of variability in demographically adjusted verbal and performance IQ indices. Reading measures provided IQ estimates which were significantly closer to those predicted by demographic variables alone in up to 22% of individuals with fewer than 7 (across all ages) or 13 years of formal education (in the 70–87 year age range). PsWRE scores slightly outperformed WRE scores in predicting a person’s estimated verbal or performance IQ. Results are discussed in the context of previous findings using reading accuracy measures for low-frequency words with exceptional spellings in less transparent orthographic systems such as English.

    We explore the psychosocial, demographic, and maternal characteristics across wanted, mistimed, and unwanted pregnancies. Data from 1321 women from a prospective cohort study of pregnant women in Durham, NC, are analyzed. Psychosocial correlates were obtained through prenatal surveys; electronic medical records were used to ascertain maternal health and pregnancy outcomes. Sixty-two percent of the women indicated an unintended pregnancy, with 44% (578) mistimed and 18% (245) unwanted. Only 38% of the pregnancies were characterized as wanted. Women with unwanted and with mistimed pregnancies were similar demographically, but they differed significantly on psychosocial profiles and maternal characteristics. Women with mistimed and with wanted pregnancies differed in demographics and psychosocial profiles. Wanted pregnancies had the healthiest, mistimed an intermediate, and unwanted the poorest psychosocial profile. Women with unwanted pregnancies had the highest depression, perceived stress, and negative paternal support scores (ppsychosocial profiles had higher odds of being in the unwanted category. Controlling for psychosocial and demographic variables, perceived stress and positive paternal support remained significant predictors of belonging to the unwanted and mistimed groups. Fully characterizing pregnancy intention and its relationship to psychosocial profiles may provide a basis for identifying women with highest risk during pregnancy and early motherhood. Women with unwanted and mistimed pregnancies may appear similar demographically but are different psychosocially. Women with unwanted pregnancies have multiple risk factors and would benefit from targeted interventions.

    Full Text Available In the present note, we present the main features of recent trends in vital family-demographic behavior in Sweden. For this purpose, published indices of marriage, divorce, and childbearing risks by calendar year are updated by adding another two or three years of observation to our series. We demonstrate that the latest trend reversal in Swedish birth rates, which occurred at the end of the 1990s, continued to manifest itself in increasing propensities for childbearing during the early years of the 21st century. The rise pertains to all birth orders. Marriage propensities showed an increase as well, however, to a large extent expressed in a short-term development that was prevalent at the turn of the millennium. The previous long-term trend of rising divorce risks leveled off during the first two years of the new century.

    When searching for alternative methods to animal testing, confidently rescaling an in vitro result to the corresponding in vivo classification is still a challenging problem. Although one of the most important factors affecting good correlation is sample characteristics, they are very rarely integrated into correlation studies. Usually, in these studies, it is implicitly assumed that both compared values are error-free numbers, which they are not. In this work, we propose a general methodology to analyze and integrate data variability and thus confidence estimation when rescaling from one test to another. The methodology is demonstrated through the case study of rescaling the in vitro Direct Peptide Reactivity Assay (DPRA) reactivity to the in vivo Local Lymph Node Assay (LLNA) skin sensitization potency classifications. In a first step, a comprehensive statistical analysis evaluating the reliability and variability of LLNA and DPRA as such was done. These results allowed us to link the concept of gray zones and confidence probability, which in turn represents a new perspective for a more precise knowledge of the classification of chemicals within their in vivo OR in vitro test. Next, the novelty and practical value of our methodology introducing variability into the threshold optimization between the in vitro AND in vivo test resides in the fact that it attributes a confidence probability to the predicted classification. The methodology, classification and screening approach presented in this study are not restricted to skin sensitization only. They could be helpful also for fate, toxicity and health hazard assessment where plenty of in vitro and in chemico assays and/or QSARs models are available. Copyright © 2016 John Wiley & Sons, Ltd.

    Chemotherapy-induced nausea and vomiting is one of the most concerning adverse drug effects from cytotoxic chemotherapy. Despite appropriate use of antiemetic guidelines, 20-30 % of patients experience breakthrough nausea and vomiting secondary to chemotherapy. To assess the variability of 5-hydroxytryptamine type 3 receptor antagonist efficacy caused by genetic variation, a review of the available literature was conducted. From the literature, three sources of pharmacogenomic variability were identified: polymorphisms associated with 5-hydroxytryptamine type 3 receptor subunits, drug metabolism via cytochromes P450, and drug transport in the body. Testing for receptor subunit polymorphisms is not applicable to a clinical setting at this time; however, cytochrome P450 2D6 testing is FDA-approved and widely accessible. Cytochrome P450 2D6 ultrarapid metabolizers and poor metabolizers displayed altered antiemetic efficacy when compared with intermediate metabolizers and extensive metabolizers. We postulate that testing for cytochrome P450 2D6 phenotypes may be the most accessible way to provide individualized antiemetic therapy in the future.

    Summary To account for the double‐edged nature of demographic workplace diversity (i.e,. relational demography, work group diversity, and organizational diversity) effects on social integration, performance, and well‐being‐related variables, research has moved away from simple main effect approaches and started examining variables that moderate these effects. While there is no shortage of primary studies of the conditions under which diversity leads to positive or negative outcomes, it remains unclear which contingency factors make it work. Using the Categorization‐Elaboration Model as our theoretical lens, we review variables moderating the effects of workplace diversity on social integration, performance, and well‐being outcomes, focusing on factors that organizations and managers have control over (i.e., strategy, unit design, human resource, leadership, climate/culture, and individual differences). We point out avenues for future research and conclude with practical implications. © 2015 The Authors. Journal of Organizational Behavior published by John Wiley & Sons, Ltd PMID:28239234

    Full Text Available The proper evaluation of accounting objects influences essentially upon the reliability of assessing the financial situation of a company. Thus, the problem in accounting estimate is quite relevant. The works of home and foreign scholars on the issues of assessment of accounting objects, regulatory and legal acts of Ukraine controlling the accounting and compiling financial reporting are a methodological basis for the research. The author uses the theoretical methods of cognition (abstraction and generalization, analysis and synthesis, induction and deduction and other methods producing conceptual knowledge for the synthesis of theoretical and methodological principles in the evaluation of assets accounting, liabilities and equity. The tabular presentation and information comparison methods are used for analytical researches. The article considers the modern approaches to the issue of evaluation of accounting objects and financial statements items. The expedience to keep records under historical value is proved and the articles of financial statements are to be presented according to the evaluation on the reporting date. In connection with the evaluation the depreciation of fixed assets is considered as a process of systematic return into circulation of the before advanced funds on the purchase (production, improvement of fixed assets and intangible assets by means of including the amount of wear in production costs. Therefore it is proposed to amortize only the actual costs incurred, i.e. not to depreciate the fixed assets received free of charge and surplus valuation of different kinds.

    Sources of demographic data for Venezuela include 11 population censuses conducted between 1873-1981, birth and death registration statistics, and the household sample survey. The average annual rate of population growth increase from 2.8% between 1920-40 to 3-4% thereafter. The population at the 1961 census was 7.52 million. According to preliminary data from the 1981 census, the population of 14.57 million is growing at an annual rate of 2.8%. 41.2% of the population is under 15 years old, implying a huge demand for educational and health services, housing and employment. The dependency rate in 1980 was 81.3% for the country as a whole, 100.4% in rural areas, and 76.0% in urban areas. The young age structure means that the population will continue to grow even if natality rates decline. The crude natality rate was estimated at 47.3/1000 for 1950-55, 36.0 for 1970-75, and 32.9 for 1980-85. Some rural areas still have natality rates of over 47/1000. The total fertility rate declined from 6.5 in 1950-55 to 4.1 in 1980-85. The decline in the natality rate reflects improving quality of life, availability of family planning services, urbanization, and access of women to productive activities and educational centers. The mortality rate was 12.3/1000 in 1950-55, 9.1 in 1960-65, in 1970-75, and has been estimated at 5.5 for 1980-85. Some rural areas have mortality rates of 8.1. The infant mortality rate was 50.2/1000 in 1971 and 34.3 in 1980. Life expectancy at birth is about 69 years. During the 1920s, Venezuela unerwent expansion in infrastructure and technological utilization, generating rapid urbanization. 39.2% of the population was urban in 1941, compared to 78.8% in 1980. The significance of urbanization in Venezuela is due to the rapidity as well as the diffusion of the process. The household sample survey for the 2nd half of 1980 indicated a total of 8.16 million employed and an activity rate of 32.1% overall, 46.4% for males and 17.7% for females. The

    This paper reviews and synthesizes findings from scholarly work on linkages among rural household demographics, livelihoods and the environment. Using the livelihood approach as an organizing framework, we examine evidence on the multiple pathways linking environmental variables and the following demographic variables: fertility, migration, morbidity and mortality, and lifecycles. Although the review draws on studies from the entire developing world, we find the majority of micro-level studies have been conducted in either marginal (mountainous or arid) or frontier environments, especially Amazonia. Though the linkages are mediated by many complex and often context-specific factors, there is strong evidence that dependence on natural resources intensifies when households lose human and social capital through adult morbidity and mortality, and qualified evidence for the influence of environmental factors on household decision-making regarding fertility and migration. Two decades of research on lifecycles and land-cover change at the farm level have yielded a number of insights about how households make use of different land-use and natural resource management strategies at different stages. A thread running throughout the review is the importance of managing risk through livelihood diversification, ensuring future income security, and culture-specific norms regarding appropriate and desirable activities and demographic responses. Recommendations for future research are provided.

The results showed that the scales usually present high levels of reliability, average results superior to those expected in the subjective well-being measures and multiple correlation coefficient of 0.79 on the prediction of total happiness. When testing the differences among the several groups, it was verified that women, young people, those married or dating, those who had a religion, studied the first grade in a private school or the college in a public institution, those who know other languages with higher family income, having parents with high level of education or social-economic status, showed to be significantly more popular, less solitaires, more satisfied with their lives and happier.

    In 2011, the AAVSO conducted a survey of 615 people who are or were recently active in the 101-year old organization. The survey included questions about their demographic background and variable star interests. Data are descriptively analyzed and compared with prior surveys. Results show an organization of very highly educated, largely male amateur and professional astronomers distributed across 108 countries. Participants tend to be loyal, with the average time of involvement in the AAVSO reported as 14 years. Most major demographic factors have not changed much over time. However, the average age of new members is increasing. Also, a significant portion of the respondents report being strictly active in a non-observing capacity, reflecting the growing mission of the organization. Motivations of participants are more aligned with scientific contribution than with that reported by other citizen science projects. This may help explain why a third of all respondents are an author or co-author of a paper in an ...

  20. Entropy Based Modelling for Estimating Demographic Trends.

    Directory of Open Access Journals (Sweden)

    Guoqi Li

    Full Text Available In this paper, an entropy-based method is proposed to forecast the demographical changes of countries. We formulate the estimation of future demographical profiles as a constrained optimization problem, anchored on the empirically validated assumption that the entropy of age distribution is increasing in time. The procedure of the proposed method involves three stages, namely: 1 Prediction of the age distribution of a country's population based on an "age-structured population model"; 2 Estimation the age distribution of each individual household size with an entropy-based formulation based on an "individual household size model"; and 3 Estimation the number of each household size based on a "total household size model". The last stage is achieved by projecting the age distribution of the country's population (obtained in stage 1 onto the age distributions of individual household sizes (obtained in stage 2. The effectiveness of the proposed method is demonstrated by feeding real world data, and it is general and versatile enough to be extended to other time dependent demographic variables.

    Full Text Available Problem statement: Social trust is the main theme in the social life. Trust is “the expectation that arises within a community of regular, honest and cooperative behavior, based on commonly shared norms”. Development, social trust and security are intertwined categories and have interaction to each other. Social trust, as a main factor in social capital, provide social context for developmental programs. This study, examine the affect of Demographic factors on the social trust to others. As social trust is a key factor in social relationship, this study is needed to evaluate such factor according to demographic factors. Approach: This study has been done on existing data about Iranian values and attitudes. Some factors such as gender, age, education level, job situation, marital situation have been studied in this study. Some of these variables such as education, correspondence to development level, especially in social development. This study is done via documental method (archive and Documental data about mentioned themes and second analysis of The Iranian National Values and attitudes Survey (2000. Results: Findings of this study indicated that there is significant relationship between all of independent variables (Gender, age, education level, job situation, marital situation and social trust to families and relatives, there is significant relationship between variables such as gender, education level, job situation, marital situation (independent variables and social trust to friends. Analyzing the data showed that, the residents of less and more developed cities have different situation in trust. Conclusion/Recommendations: This study introduces three types of trust upon the development level of societies. Trust in Iran is an example of trust structure in developing societies.

    Full Text Available One of the most notable recent developments in survey research is the increased usage of online convenience samples drawn from Amazon’s Mechanical Turk (MTurk. While scholars have noted various social and political differences (e.g., age, partisanship between MTurk and population-based samples, the breadth and depth of these variations remain unclear. We investigate the extent to which MTurk samples differ from population samples, and the underlying nature of these differences. We do so by replicating items from the population-based American National Election Studies (ANES 2012 Time Series Study in a survey administered to a sample of MTurk respondents. With few exceptions, we not only find that MTurk respondents differ significantly from respondents completing the 2012 ANES via the Web but also that most differences are reduced considerably when controlling for easily measurable sample features. Thus, MTurk respondents do not appear to differ fundamentally from population-based respondents in unmeasurable ways. This suggests that MTurk data can be used to advance research programs, particularly if researchers measure and account for a range of political and demographic variables as needed.

    Full Text Available The paper considers the transformations of the quantitative components of human capital, which is the main driver of economic growth in the material, institutional and mental space. According to the author’s concept of stratified space, the processes of self-reproduction and self-renewal of a system are carried out in the material space. This can be determined by the indicators of fertility, mortality and migration in the demographic subsystem. The process of self-regulation of a system on the basis of legislative acts and behavior patterns is carried out in the institutional space. Institutional transformations are also manifested in the implementation of federal target programs for socio-economic development, affecting the state of the demographic subsystem. The processes of self-reflection, self-determination and self-development are carried out in the mental space. Mental transformations in the demographic subsystem are manifested in the change of value orientations. In accordance with the system of values that are conceptualized in modern development strategies the authors define the following models of Man: Economic Man, Socio-Economic Man (who lives in agglomeration centers and at the periphery, Socio-Natural Man (Environmental Man and Householder Man and Innovative Man. Demographic shifts are investigated in 83 Russian regions on the determinants of birth rate and mortality. The analyzed period of transformation covers 2005 and 2012. Methods of matrix analysis are used to visualize the process of demographic shifts. The assessment of transformation of the stratified regional space spheres is given on the basis of the multifactor models of the population natural growth rate. The paper reveals the reduction in the level and variation of mortality rate, the increasing importance and differentiation of regions according to fertility rate, and the effectiveness of introducing the institution of maternity capital from a perspective of the

    Full Text Available This is a descriptive and correlational study, whose main objective was to relate personality traits to antisocial behavior. For doing so, socio-demographic variables of a group of soccer fans were takeninto account. The sample was constituted by 70 soccer fans of Millonarios, Santa Fe and Nacional–Colombian soccer teams-. The Eysenck Personality Questionnaire for children (J and adults (A,The Seisdedos Criminal and Antisocial Behavior Questionnaire and the socio-demographic variables survey- developed by the researchers-, were the instruments applied. The results showed correlationsbetween personality traits, socio-demographic variables and antisocial behavior. So, it could be concluded that psychoticism and extraversion have a high positive correlation with antisocialbehavior. In terms of socio-demographic variables, age was the only one which presented significant differences between the groups. In fact, youth from 16 to 17 years old presented more antisocialbehaviors. For further research, it is recommended to use a larger sample and a comparison group.

  11. Democratic constraints on demographic policy.

    Grigsby, J S

    1984-01-01

    The discussion compares the population policies adopted in Sweden during the 1930s to raise fertiity and the policies considered in the US during the 1970s in response to the high fertility experienced in the 1950s. Both sets of policies recommended increased availability of birth control, more liberal abortion laws, and greater employment opportunities for women. It becomes evident that the constraints imposed by a democratic system of government translate into policy recommendations that place individual freedom of choice and equal opportunity for all citizens as higher goals than any specific demographic target. Consequently, the population commissions of Sweden and the US made similar suggestions on how to resolve their opposite demographic problems. The demographic situations in the 2 nations were antipodal, and the countries also had very different social climates. This additional disparity was insufficient to counterbalance the apparently overwhelming influence of the democratic political systems in making virtually identical policy recommendations. Yet, the contrasting social climates of Sweden in 1935 and the US in 1970-72 may explain the different reactions each commission received. In terms of the responses by both citizens and government officials to the commissions' reports, the Swedish commission was more successful. Practically all of their recommendations were enthusiastically received and quickly adopted by the Swedish Riksdag. Yet, when the criterion for success becomes whether or not a demographic target was met, it increased in the 1940s and then dropped again while the same social policies were in effect. Even before the US commission began its study, fertility in the US had fallen and continues to remain low. These findings suggest that commissions in democratic countries will most likely never recommend dramatic measures in population policy. Thus, it is questionable whether such commissions in democratic nations will totally fulfill the

    2012-05-01

    The article considers dynamic processes involving non-linear power-law behavior in such apparently diverse spheres, as demographic dynamics and dynamics of prices of highly liquid commodities such as oil and gold. All the respective variables exhibit features of explosive growth containing precursors indicating approaching phase transitions/catastrophes/crises. The first part of the article analyzes mathematical models of demographic dynamics that describe various scenarios of demographic development in the post-phase-transition period, including a model that takes the limitedness of the Earth carrying capacity into account. This model points to a critical point in the early 2050s, when the world population, after reaching its maximum value may decrease afterward stabilizing then at a certain stationary level. The article presents an analysis of the influence of the demographic transition (directly connected with the hyperexponential growth of the world population) on the global socioeconomic and geopolitical development. The second part deals with the phenomenon of explosive growth of prices of such highly liquid commodities as oil and gold. It is demonstrated that at present the respective processes could be regarded as precursors of waves of the global financial-economic crisis that will demand the change of the current global economic and political system. It is also shown that the moments of the start of the first and second waves of the current global crisis could have been forecasted with a model of accelerating log-periodic fluctuations superimposed over a power-law trend with a finite singularity developed by Didier Sornette and collaborators. With respect to the oil prices, it is shown that it was possible to forecast the 2008 crisis with a precision up to a month already in 2007. The gold price dynamics was used to calculate the possible time of the start of the second wave of the global crisis (July-August 2011); note that this forecast has turned out

    The theory of salutogenesis entails that the ability to use resources for one's wellbeing is more important than the resources themselves. This ability is referred to as the Sense of Coherence (SOC). This paper present the cross-culturally adapted version of the Italian questionnaire (13 items), and the psychometric and statistical testing of the SOC properties. It offers for the first time a view of the distribution of SOC in an Italian sample, and uses a multivariate method to clarify the effects of socio-demographic determinants on SOC. The cross-cultural adaptation of the English SOC questionnaire was carried out according to the guidelines reported in literature. To evaluate the psychometric and statistical properties we assessed reliability, validity and frequency distribution of the collected data. A Generalised Linear Model was used to analyse the effects of socio demographic variables on SOC. The Italian SOC scale demonstrates a good internal consistency (α = 0.825). The model obtained with factorial analysis is not related to the traditional dimensions of SOC represented in more than one factor. The multivariate analysis highlights the joint influence of gender, age and education on SOC. The validated Italian questionnaire is now available. Socio-demographic variables should be taken into account as confounders when SOC values among different populations are compared. Presenting data on SOC of the Italian population makes a control population available for comparisons with specific subgroups, such as patient populations. Now, the Italian challenge is to integrate the salutogenic approach into Public Health police.

    Associations between contaminated land and socio demographics are well documented in high-income countries. In low- and middle-income countries, however, little is known about the extent of contaminated land and possible demographic correlations. This is an important yet sparsely researched topic with potentially significant public health implications as exposure to pollution remains a leading source of morbidity and mortality in low-income countries. In this study, we review the associations between several socio demographic factors (population, population density, unemployment, education, and literacy) and contaminated sites in Ghana. Within this context, both correlation and association intend to show the relationship between two variables, namely contaminated sites and socio demographics. Aggregated district level 2010 census data from Ghana Statistical Service and contaminated site location data from Pure Earth's Toxic Sites Identification Program (TSIP) were spatially evaluated using the number of sites per kilometer squared within districts as the unit of measurement. We found a low to medium positive correlation (ρ range: 0.285 to 0.478) between contaminated sites and the following socio demographics: higher population density, higher unemployment, greater education, and higher literacy rate. These results support previous studies and suggest that several socio demographic factors may be reasonably accurate predictors of contaminated site locations. More research and targeted data collection is needed to better understand these associations with the ultimate goal of developing a predictive model.

    Evolutionary processes of natural selection may be expected to leave their mark on age patterns of survival and reproduction. Demographic theory includes three main strands—mutation accumulation, stochastic vitality, and optimal life histories. This paper reviews the three strands and, concentrating on mutation accumulation, extends a mathematical result with broad implications concerning the effect of interactions between small age-specific effects of deleterious mutant alleles. Empirical data from genomic sequencing along with prospects for combining strands of theory hold hope for future progress. PMID:25024186

    This study investigated the factor structure of observational indicators of children's temperament that were collected across the first three years of life in the Family Life Project (N=1205) sample. A four-factor model (activity level, fear, anger, regulation), which corresponded broadly to Rothbart's distinction between reactivity and regulation, provided an acceptable fit the observed data. Tests of measurement invariance demonstrated that a majority of the observational indicators exhibited comparable measurement properties for male vs. female, black vs. white, and poor vs. not-poor children, which improved the generalizability of these results. Unadjusted demographic group comparisons revealed small to moderate sized differences (Cohen ds=|.23-.42|) in temperamental reactivity and moderate to large sized differences (Cohen ds=-.64--.97) in regulation. Collectively, demographic variables explained more of the variation in regulation (R(2)=.25) than in reactivity (R(2)=.02-.06). Follow-up analyses demonstrated that race differences were substantially diminished in magnitude and better accounted for by poverty. These results help to validate the distinction between temperamental reactivity and regulation using observational indicators.

    The cognitive styles of 113 practicing, professional accountants from Nova Scotia, Canada were examined using the Group Embedded Figures Test. They completed a demographic survey for descriptive information as well as their rank in the firm and preferred area of professional practice. Analysis suggested professional accountants tend to be more analytical than intuitive in cognitive style and, consistent with recent findings in other fields, men and women in accounting do not appear to be different in cognitive style. No statistically significant differences were found on the embedded figures scores across ranks of trainee, manager, and partner or across select, preferred areas of professional practice.

    Objective To obtain distinct dietary patterns in the third trimester of pregnancy using principal components analysis (PCA); to determine associations with socio-demographic and lifestyle factors. Design and methods A total of 12 053 pregnant women partaking in a population-based cohort study recorded current frequency of food consumption via questionnaire in 1991-1992. Dietary patterns identified using PCA were related to social and demographic characteristics and lifestyle factors. Results Five dietary patterns were established and labelled to best describe the types of diet being consumed in pregnancy. The ‘health conscious’ component described a diet based on salad, fruit, rice, pasta, breakfast cereals, fish, eggs, pulses, fruit juices, white meat and non-white bread. The ‘traditional’ component loaded highly on all types of vegetables, red meat and poultry. The ‘processed’ component was associated with high-fat processed foods. The ‘confectionery’ component was characterized by snack foods with high sugar content and the final ‘vegetarian’ component loaded highly on meat substitutes, pulses, nuts and herbal tea and high negative loadings were seen with red meat and poultry. There were strong associations between various socio-demographic variables and all dietary components; in particular, a ‘health conscious’ diet was positively associated with increasing education and age and non-white women. There was a negative association with increased parity, single, non-working women, those who smoked and who were overweight pre-pregnancy. Opposite associations were seen with the ‘processed’ component. Conclusions Distinct dietary patterns in pregnancy have been identified. There is clear evidence of social patterning associated with the dietary patterns, these social factors need to be accounted for in future studies using dietary patterns. This study will form the basis for further work investigating pregnancy outcome. PMID:17375108

    Full Text Available The article presents, in a simplifi ed manner, selected theories of population to explain the current trends of population development in Poland and throughout the world. The aim of the article is to present the demographic threats that have emerged in the last eighty years. Prognosticated age structures have also been predicted. Signifi cant diff erences between the structure of the population now and the future have been indicated, particularly regarding the ageing of the population. Against the background of global transformations analyzes of changes in Poland have been conducted. The comparison shows that changes in Poland are highly analogous to transformations around the world, such as declining birth rates and increasing life expectancy. These changes cause ageing of the population, which could result in the collapse of the functioning of the labor market and the pension system as it currently exists.

    Full Text Available Objective – The investigators hoped to gain an understanding of the extent to which local public libraries are used by their visitors as meeting places, and in what ways. Furthermore, they sought to determine whether certain demographic variables correlate with variations in these ways of using the library. Finally, they were looking for evidence of a relationship between the degree of the subjects’ general community involvement on the one hand, and their participation in various types of meetings in the library on the other.Design – Questionnaire-based telephone survey.Setting – Oslo, Norway.Subjects – 750 adult residents (eighteen years or older from 3 of Oslo’s 15 boroughs.Methods – The researchers selected these boroughs (not identified in this article and referred to, unusually, as “townships” because they judged them to represent three demographically varying types of urban community. In March of 2006, a professional survey organization drew numbers at random from a database of telephone numbers in each borough, continuing until it had reached the desired number of 250 actual survey respondents, including cell phone users, for each borough. It weighted the sample according to gender and age, and administered the telephone interviews on the basis of a questionnaire which the researchers had designed to yield quantitative data for ten independent, and seven dependent, variables. Interviewers asked the respondents to answer questions on the basis of their entire recollected personal history of public library use, rather than during a specific defined period.Six of the independent variables were demographic: borough of residence, occupational category, age category, educational level, cultural/linguistic background (dichotomous: either non-Norwegian or Norwegian, and household income category.

  4. Demographic Ageing on Croatian Islands

    Full Text Available This paper analyses the changes in the population structure of the Croatian islands by age, warns of the degree of ageing, provides spatial differentiation of this process and presents perspective of ageing at the level of settlement. Typing of population ageing is based on scores and has seven types. The total island population in 2011 belongs to the type 5 – very old population. Almost a half of the settlements (out of 303 have been affected by the highest levels of ageing (types 6 and 7. It was found that a quarter of island settlements will become “dead villages” in a foreseeable future; most of them are on small islands but also in the interior of larger islands. These are villages decaying in every respect, in which the way of life, as we know it, veins and goes out. The present ageing villagers are their last residents in most cases. Eve¬rything suggests that demographic recovery of the islands is not possible with the forces in situ. It is important to strike a balance between the needs and opportunities in order to successfully organize life on the islands, both small and large ones, and the fact is that there is a continuing disparity, which is especially profound in small islands. A sensitive and selective approach is needed to overcome the unfavourable demographic trends. Therefore it is necessary to respect the particularities of indi¬vidual islands and island groups in devising development strategy. Solutions to the problems must come of the local and wider community in synergy with relevant professional and scientific institutions. However, if the solutions are not found or measures do not give results, if the islands are left to desorganisation and senilisation, a part of the islands will become a wasteland. With regard to the value of this area whose wealth are people in the first place, this would be an intolerable civilization decline.

    The Safeguards Accountability Network (SAN) is a computerized on-line accountability system for the safeguards accountability control of nuclear materials inventories at Rocky Flats Plant. SAN is a dedicated accountability system utilizing source documents filled out on the shop floor as its base. The system incorporates double entry accounting and is developed around the Material Balance Area (MBA) concept. MBA custodians enter transaction information from source documents prepared by personnel in the process areas directly into the SAN system. This provides a somewhat near-real time perpetual inventory system which has limited interaction with MBA custodians. MBA custodians are permitted to inquire into the system and status items on inventory. They are also responsible for the accuracy of the accountability information used as input to the system for their MBA. Monthly audits by the Nuclear Materials Control group assure the timeliness and accuracy of SAN accountability information.

    2010-01-01

    Background There is a lack of studies considering social disparity in oral health emanating from adolescents in low-income countries. This study aimed to assess socio-demographic disparities in clinical- and self reported oral health status and a number of oral health behaviors. The extent to which oral health related behaviors might account for socio-demographic disparities in oral health status was also examined. Methods A cross-sectional study was conducted in Kilwa district in 2008. One thousand seven hundred and forty five schoolchildren completed an interview and a full mouth clinical examination. Caries experience was recorded using WHO criteria, whilst type of treatment need was categorized using the ART approach. Results The majority of students were caries free (79.8%) and presented with a low need for dental treatment (89.3%). Compared to their counterparts in opposite groups, rural residents and those from less poor households presented more frequently with caries experience (DMT>0), high need for dental treatment and poor oral hygiene behavior, but were less likely to report poor oral health status. Stepwise logistic regressions revealed that social and behavioral variables varied systematically with caries experience, high need for dental treatment and poor self reported oral health. Socio-demographic disparities in oral health outcomes persisted after adjusting for oral health behaviors. Conclusions Socio-demographic disparities in oral health outcomes and oral health behaviors do exist. Socio-demographic disparities in oral health outcomes were marginally accounted for by oral health behaviors. Developing policies and programs targeting both social and individual determinants of oral health should be an urgent public health strategy in Tanzania. PMID:20406452

In this paper, we used CANOPY, a spatially explicit, individual‐tree model, to examine the effects of initial size distributions on sustainability of tree populations for 70 northern hardwood stands under current environmental conditions. A demographic sustainability index was calculated as the ratio of future simulated basal area to current basal area, given current demographic structure and density‐dependent demographic equations. Only steeply descending size distributions were indicated to be moderately or highly sustainable (final basal area/initial basal area ≥0.7 over several tree generations. Five of the six principal species had demographic sustainability index values of <0.6 in 40%–84% of the stands. However, at a small landscape scale, nearly all species had mean index values >1. Simulation experiments suggested that a minimum sapling density of 300 per hectare was required to sustain the initial basal area, but further increases in sapling density did not increase basal area because of coincident increases in mortality. A variable slope with high q‐ratios in small size classes was needed to maintain the existing overstory of mature and old‐growth stands. This analytical approach may be useful in identifying stands needing restoration treatments to maintain existing species composition in situations where forests are likely to have future recruitment limitations.

  11. CONSEQUENCES OF THE DEMOGRAPHIC CRISIS

    LIVIU RADU

    2014-11-01

    Full Text Available Major dysfunctionalities can arise from the demographic decline, both on a social level and from the perspective of the economic-financial evolution of the world’s states. The obvious aging of the industrialized states’ population overlapping the import of cheap workforce in the developing countries can start mutations whose consequences are somewhat predictable but discouraging. An accelerated urbanization of the states is foreseen, as well as the decrease of birthrates, negative external migration, increase of mortality and its stagnation in a larger value than that of the birthrate, and not least the population’s aging will hinder a part of the developing countries to sustain a high rhythm of long-term economical increase. The socialeconomic consequences will be reflected in the labor market, the householders’ amount of income as well as in the education’s level. All of these aspects call for a rethinking of the public politics, especially of the social insurance’s system and of the education, a reorientation of the economy based on the increase of specializing in production and productivity, as well as a financial stability unburdened by the politics’ interference in the business environment.

  13. The demographic transition: an attempt to reformulate a population theory.

    Science.gov (United States)

    Hofsten, E

    1981-01-01

    In this effort to reformulate the demographic transition theory, attention is directed to the following: Malthus and Karl Marx's criticism of his principle of population; the 1st stage of transition, i.e., high mortality, high fertility, and slow population growth; the 2nd stage of declining mortality; the 3rd stage of declining fertility; the 4th stage when mortality and fertility are both low; the growth potential; and the demographic transition in the 3rd world countries. The demographic transition theory has become popular among demographers, economists, historians, and others interested in studying the development of population over time since the end of World War 2. This interest has most likely been created by the anxiety over the population explosion in the 3rd world countries. Transition has made demographers believe that the period of rapid population growth will be automatically succeeded by a period of more or less constant population size. The question that arises is whether it is as simple as that. Demographic transition has to a great extent taken the place of Malthus' principle of population as a general theory of population. Demographic transition appears to describe in a satisfactory way the development of population which all currently industrialized countires have passed through, when going from the preindustrial to the present industrialized stage. The objectives to demographic transition as a general theory are considered. Some of the factors which have accounted for the decline in fertility in Europe may also apply to the 3rd world countries. 1 such factor is the effect of reduced infant and child mortality on the individual level. The fertility decline, caused by reduced infant and child mortality may, however, be of limited size. The great amount of unemployment in the 3rd world may affect fertility in a downward direction. The fertility decline in Europe occurred simultaneously with an industrialization process, which gradually covered the

    2009-01-01

    Full Text Available Background: The study investigates the role of certain demographic variables in determining stress-coping behavior of female teachers. Materials and Methods: The sample consists of 150 female teachers selected by stratified sampling method from various schools of Bhopal. Stress-coping behavior was measured with the help of a subscale of ′The Occupational Stress Indicator′ (Wendy Lord, 1993 consisting of 28 items encompassing six dimensions of coping strategies i.e. Logics, Involvement, Social Support, Task Strategies, Time Management and Home and Work Relations. The scores of the subjects were compared in terms of marital status, age, and level of teaching with the help of ′t′ test and ′F′ test was used for comparing experience. Results: Marital status, age, and experience were found to be significant determinants of stress-coping, whereas the sores did not differ significantly on the basis of level of teaching. Conclusion: Married teachers in the age range of 40-60 years, with higher experience can cope better with the job stress than their counterparts.

    Addicott, Rachael; Shortell, Stephen M

    2014-01-01

    The establishment of accountable care organizations (ACOs) in the Affordable Care Act (ACA) was intended to support both cost savings and high-quality care. However, a key challenge will be to ensure that governance and accountability mechanisms are sufficient to support those twin ambitions. This exploratory study considers how recently developed ACOs have established governance structures and accountability mechanisms, particularly focusing on attempts at collaborative accountability and shared governance arrangements. Four case studies of ACOs across the United States were undertaken, with data collected throughout 2012. These involved 34 semistructured interviews with ACO administrative and clinical leaders, observation of nine meetings, and a review of documentary materials from each ACO. We identified very few examples of physicians being held to account as a collective and therefore only limited evidence of collaborative accountability impacting on behavior change. However, ACO leaders do have many mechanisms available to stimulate change across physicians. The challenge is to determine governance structure(s) and accountability mechanisms that facilitate the most effective combination of approaches, measures, incentives, and sanctions to achieve the goals of more accountable care. Accountability structures and processes will need to be tailored to local membership composition, historical evolution, and current stage of development. There are also some common lessons to be drawn. Shared goals and incentives should be reflected through performance criteria. It is important to align measures and thresholds across payers to ensure ACOs are not unnecessarily burdened or compromised by reporting on different and potentially disjointed measures. Finally, emphasis needs to be placed on the importance of credible, transparent data. This exploratory study provides early evidence regarding how ACOs are establishing their governance and accountability arrangements and

    Professional burnout results from prolonged exposure to chronic, job-related stressors. According to Christina Maslach, professional burnout is a syndrome of emotional exhaustion, depersonalization and reduced personal accomplishment. Literature includes a number of reports on burnout syndrome within health service, but hardly ever do they make any references to physiotherapists. The purpose of this study is assessment of the level of professional burnout in a group of physiotherapists and investigating relationships between the indices of burnout syndrome and selected demographic as well as organizational variables. The study group consisted of 151 physiotherapists with at least 3 years of experience, employed in various health service outposts in Krakow, Poland. The Maslach Burnout Inventory (MBI) was used to measure emotional exhaustion, depersonalization and personal accomplishment. A questionnaire for the description of socio-demographic and work characteristics was used as well. Job burnout among the physiotherapists was manifested by an increased emotional exhaustion and decreased sense of personal achievement. Emotional exhaustion was significantly higher among physi cal therapists working with adults and employed in hospitals, depersonalization was higher among men, hospital workers and employees with seniority from 15 to 19 years, personal accomplishment was decreased among men and less-educated therapists. The study confirmed that indicators of burnout in physiotherapists are significantly associated with selected demographic and organizational variables. It is necessary to undertake a more exhaustive study of burnout in this group of employees, and implement elements of prevention.

    When it comes to knowledge of demographic facts, misinformation appears to be the norm. Americans massively overestimate the proportions of their fellow citizens who are immigrants, Muslim, LGBTQ, and Latino, but underestimate those who are White or Christian. Previous explanations of these estimation errors have invoked topic-specific mechanisms such as xenophobia or media bias. We reconsidered this pattern of errors in the light of more than 30 years of research on the psychological processes involved in proportion estimation and decision-making under uncertainty. In two publicly available datasets featuring demographic estimates from 14 countries, we found that proportion estimates of national demographics correspond closely to what is found in laboratory studies of quantitative estimates more generally. Biases in demographic estimation, therefore, are part of a very general pattern of human psychology-independent of the particular topic or demographic under consideration-that explains most of the error in estimates of the size of politically salient populations. By situating demographic estimates within a broader understanding of general quantity estimation, these results demand reevaluation of both topic-specific misinformation about demographic facts and topic-specific explanations of demographic ignorance, such as media bias and xenophobia.

    2014-01-01

    Demographic analysis seeks to understand how individual microlevel decisions about child-bearing, marriage and partnering, geographic mobility, and behaviors that influence health and longevity aggregate to macrolevel population trends and differentials in fertility, mortality and migration. In this review, I first discuss theoretical perspectives—classic demographic transition theory, the perspective of the “second demographic transition,” the spread of developmental idealism—that inform demographers’ understanding of macrolevel population change. Then, I turn to a discussion of the role that demographically informed data collection has played in illuminating family change since the mid-20th century in the United States. Finally, I discuss ways in which demographic theory and data collection might inform future areas of family research, particularly in the area of intergenerational family relationships and new and emerging family forms.

    The Safeguards Accountability Network (SAN) is an on-line accountability system used by Rocky Flats Plant to provide accountability control of its nuclear material inventory. The system is also used to monitor and evaluate the use of the nuclear material inventory against programmatic objectives for materials management. The SAN system utilizes two Harris 800 Computers as central processing units. Enhancement plans are currently being formulated to provide automated data collection from process operations on the shop floor and from non-destructive analysis safeguards instrumentation. SAN, discussed in this paper, is an excellent system for basic accountability control of nuclear materials inventories and is a quite useful tool in evaluating the efficient use of nuclear materials inventories at Rocky Flats Plant.

    Full Text Available Using the 2012 Latino Immigrant National Election Study, the 2012 American National Election Study, and the 2012 Current Population Survey, we document the demographic factors that influenced Latino (native-born and immigrant voter turnout and participation in the 2012 presidential election. We estimate multivariable models of turnout and participation, including standard demographic characteristics (education, income, age, gender, marital status as explanatory variables. Our findings indicate that the relationships between these characteristics and participation are much less consistent across these datasets than the conventional wisdom would suggest. Understanding these results likely requires survey data—with large sample sizes—including information on the resources (including education and income available to immigrants in their home countries to better understand the lingering influences of immigrants’ experiences in their countries of origin on voter turnout.

  11. [Economic adjustment and its demographic consequences in Latin America: an overview].

    Bajraj, R F; Bravo, J H

    1994-06-01

    This work reviews the available literature on short and medium term demographic responses to the economic adjustment processes occurring in Latin America during the 1980s. The first section describes the immediate causes and scope of the economic crisis of the 1980s in Latin America and the measures taken to correct imbalances. An external crisis rendered the current accounts deficit of the early 1980s no longer sustainable, interest rates and commercial conditions deteriorated, and a recessive adjustment of enormous magnitude occurred. The term "adjustment" covers a wide and varied array of economic changes, fiscal and social policy reforms, and changes in international commerce. The structural adjustment measures caused deterioration in investment and in equity. Real purchasing power declined more than per capita product in most Latin American countries between 1980 and 1990. Primary income distribution underwent regressive changes. In most cases the deterioration was not compensated by social spending. As a result of the fiscal adjustment and reduced public sector spending, per capita investment in health and education was less in 1990 than in 1980 in almost all countries. The demographic consequences of the adjustment processes are difficult to gauge precisely because the experiences of individual countries were heterogeneous and because no single definition of adjustment exists that would serve as a point of reference for comparison of situations without adjustment or with different types of adjustment. Nevertheless, some studies have attempted to specify terms of comparison. Some have compared conditions before the crisis or adjustments with conditions later, and others have analyzed short term fluctuations in demographic variables from their medium or long term trends. Such works suggest that nuptiality is the variable responding most intensely, systematically, and immediately to short term economic fluctuations. Fertility also appears to have responded

    Full Text Available Switching cost is defined as possible costs that customers may encounter when they want to change the firm they buy service, and an important subject in terms of accounting services. Particularly, small business entrepreneurs’ not having knowledge about accounting procedures, and sharing private information with accounting firms make switching costs more important for accounting services. Thus, the aim of this study is to investigate the concept of switching costs (relational cost, procedural cost and financial cost, its determinants (perceived service quality, service importance, and service failures, and consequences (re-purchasing, and recommen ding to others. Theresearch was conducted on small business entrepreneurs in down-town of Balıkesir in Turkey. Total 405 small business entrepreneur owners were interviewed. According to results of the study, perceived service quality positively affects all dimensions of switching costs, significance of service positively affects procedural and relational costs, and service failures negatively affect procedural and relational costs. The results showed that while procedural and relational costs positively affect re-purchasing and recommending to others variables, financial cost did not have any effect on these variables.

    2011-01-01

    The etiology of developmental dysplasia of the hip (DDH) is unknown. There are many insights, however, from epidemiologic/demographic information. A systematic medical literature review regarding DDH was performed. There is a predominance of left-sided (64.0%) and unilateral disease (63.4%). The incidence per 1000 live births ranges from 0.06 in Africans in Africa to 76.1 in Native Americans. There is significant variability in incidence within each racial group by geographic location. The incidence of clinical neonatal hip instability at birth ranges from 0.4 in Africans to 61.7 in Polish Caucasians. Predictors of DDH are breech presentation, positive family history, and gender (female). Children born premature, with low birth weights, or to multifetal pregnancies are somewhat protected from DDH. Certain HLA A, B, and D types demonstrate an increase in DDH. Chromosome 17q21 is strongly associated with DDH. Ligamentous laxity and abnormalities in collagen metabolism, estrogen metabolism, and pregnancy-associated pelvic instability are well-described associations with DDH. Many studies demonstrate an increase of DDH in the winter, both in the northern and southern hemispheres. Swaddling is strongly associated with DDH. Amniocentesis, premature labor, and massive radiation exposure may increase the risk of DDH. Associated conditions are congenital muscular torticollis and congenital foot deformities. The opposite hip is frequently abnormal when using rigorous radiographic assessments. The role of acetabular dysplasia and adult hip osteoarthritis is complex. Archeological studies demonstrate that the epidemiology of DDH may be changing. PMID:24977057

What is the position and importance of the computer in the accountant’s activity? All these are questions that require scientific research in order to find the answers. The paper approaches the issue of the support granted to the accountant to organize and manage the accounting activity by the computer. Starting from the notions of accounting and computer, the concept of computer-assisted accounting is introduced, it has a general character and it refers to the accounting performed with the help of the computer or using the computer to automate the procedures performed by the person who is doing the accounting activity; this is a concept used to define the computer applications of the accounting activity. The arguments regarding the use of the computer to assist accounting targets the accounting informatization, the automating of the financial-accounting activities and the endowment with modern technology of the contemporary accounting.

    2015-12-01

    This study sought to compare demographics and donation motivations among plasma/platelet donors (PPDs) and whole blood donors (WBDs), in a voluntary and non-remunerated context. Motives to donate blood and demographic characteristics were collected through questionnaires completed by 795 WBDs and 473 PPDs. Comparison of WBDs and PPDs under chi-square tests showed that 17 out of 23 motivators were statistically different according to various demographic variables. These results demonstrate the existence of specific donor profiles both for WBDs and PPDs. Agencies should develop new recruitment strategies tailored to these donors, especially if they wish to convince WBDs to convert to apheresis donation.

    During the past 2 decades, the grizzly bear (Ursus arctos) population in the Greater Yellowstone Ecosystem (GYE) has increased in numbers and expanded in range. Understanding temporal, environmental, and spatial variables responsible for this change is useful in evaluating what likely influenced grizzly bear demographics in the GYE and where future management efforts might benefit conservation and management. We used recent data from radio-marked bears to estimate reproduction (1983–2002) and survival (1983–2001); these we combined into models to evaluate demographic vigor (lambda [λ]). We explored the influence of an array of individual, temporal, and spatial covariates on demographic vigor.

    While reviewing the graphs depicting the changes in magnitude for several stars this researcher came across two very interesting light curves. These curves showed increases and decreases in luminosity with a periodicity proper of eclipsing binary star systems, group that belongs to the extrinsic variable family of the variable stars classification (1). The finding of the stars was incredibly exciting but what made the discovery even more thrilling was the fact that there was no information available nor evidence of previous studies conducted on the subjects. The data was obtained from several nights of observation using the 0.32-m and the 0.91-m telescopes at West Mountain Observatory -property of BYU- and analyzed, processed and reduced using the differential photometry technique and the IRAF incorporated system.

Estudou-se a adoção de comportamentos por mulheres para proteção das DST, tal como a associação destes a variáveis sócio-econômicas e demográficas. Trata-se de estudo descritivo, com dados secundários de pesquisa feita em Campinas, São Paulo, na qual foram entrevistadas 635 mulheres selecionadas mediante a técnica de amostragem "bola de neve". Foram classificadas em: adolescentes e adultas de status sócio-econômico médio-alto ou baixo. Grande proporção delas não se prevenia das DST, em particular, as de status baixo. Em todos os grupos, o condom masculino foi o método de prevenção mais referido. Houve associação negativa entre parceiro fixo e uso de condom, e a principal razão para não usá-lo foi "só ter um parceiro e confiar nele". Em meio às adolescentes, ocorreu associação positiva entre escolaridade acima da oitava série e uso de condom, bem como negativa entre idade e uso desse método.

    Full Text Available Objetivou-se descrever o estado nutricional dos adolescentes da 9ª série de escolas públicas e privadas das capitais brasileiras e sua associação com variáveis sociodemográficas. Por meio de questionário autopreenchido, foram registradas informações sobre sexo, raça/cor, idade, escola pública/privada, macrorregião do país, escolaridade materna e posse de bens familiares. Peso e altura foram aferidos segundo procedimentos padronizados. A altura para idade e o Índice de Massa Corporal para idade foram avaliados segundo critérios da Organização Mundial da Saúde. Obtiveram-se medidas antropométricas de 58.971 adolescentes, sendo que 2,9% apresentaram déficit estatural e 2,9% magreza. O excesso de peso foi de 23,0% e a obesidade de 7,3%, sendo mais altos no Sul e no Sudeste do país. Déficits de altura e peso, excesso de peso e obesidade foram mais prevalentes nos meninos. Os déficits foram superiores nas escolas públicas, e o excesso de peso e a obesidade nas privadas. Adolescentes cujas mães eram de menor escolaridade ou de famílias mais pobres apresentaram maior déficit de altura; o inverso ocorreu com o excesso de peso e a obesidade. Prevalências de déficits, excesso de peso e obesidade ressaltam a necessidade de intervenções nutricionais direcionadas para esta fase da vida.The aim of this study was to describe the nutritional status of adolescents in the 9th year of public and private schools of the Brazilian capitals and its association with socio-demographic variables.

    2012-12-01

    Full Text Available It is known the fact that often the entities offer to staff or third parties certain amounts of money, in order to make payments for the entities, such sums being registered differently in the accounting as cash advances. In the case in which the advances are offered in a foreign currency, there is the problem of the exchange rate used when justifying the advance, for the conversion in lei of payments that were carried out. In this article we wanted to signal the effect that the exchange rate, used in the assessment for reflecting in the accounting operations concerning cash advance reimbursements in a foreign currency, has on the information presented in the financial statement. Therewith, we signal some aspects from the content of the accounting regulations, with reference at defining the cash advances, meaning, and the presentation in the balance sheet of cash advances, which, in our opinion, impose clarifications.

    Executive functioning (EF), needed for goal-oriented behaviour, thoughts, and emotions, is important for various life domains. This study examined the relationship between family demographics and EF subcomponents. A kindergarten sample was tested on subcomponents of working memory, inhibition, and cognitive flexibility. Parents provided information on demographic variables. For 78 children both EF and demographic data were available. First, demographic profiles were identified within the sample. Two profiles were found: A low-risk profile of mainly two-biological-parent, high-income families with a highly educated mother who did not smoke during pregnancy and a high-risk profile of low-income families with a young, low-educated mother who more often smoked during pregnancy. Second, children with different demographic profiles were compared on EF subcomponents. Results indicate differential relations between family demographics and EF subcomponents: Whereas for most EF subcomponents no association with family demographics was found, high-risk children performed better on response shifting and tended to perform worse on verbal memory than low-risk children. Parenting stress decreased performance only for high-risk children. Although this study found limited impact of family demographics for EF, further longitudinal research can provide nuanced insights about which factors influence specific EF subcomponents during which developmental periods and guide targeted prevention of EF difficulties.

  13. Demographic Risks of the Pension Reform in the Russian Federation

    2016-03-01

    Full Text Available The purpose of the study is to analyze the impact of the demographic crisis in the country’s fiscal system. In the article, the pension system for the first time is considered as a multifactorial model, which during the different historical periods corrects the degree of its dependence on the interdependent complex of macroeconomic and demographic factors. The economically sound and socially correct accounting of the interference of retirement age and the specified development factors of pension system requires a fundamental change in the methodological approaches to the problem of raising the retirement age by using the actuarial methods of forecasting. The actuarial analysis of the problem of retirement age shows that the perception of the linear dependence on demographic parameters of the age when the national pension is awarded cannot be considered as a tool for regulating the efficiency of the pension system. For the science-based solution to the problem of rising the retirement age, along with the dynamics of demographic parameters, it is necessary to take into account the whole range of macroeconomic conditions for the state development as well as the long-term socio-economic consequences. Another significant result of the study are the specific parameters of the actuarial assessments of the impact of demographic and macroeconomic conditions of increasing the retirement age in Russia, conducted using the state statistical data. The practical proposals to mitigate the negative economic consequences are formulated. The key conclusion reached is that the raising of the retirement age should be aimed exclusively at the economic stimulation of the formation of the pension rights of the insured in the long term, rather than to the short-term savings of the state budget. The methodological approaches grounded in the work, and the quantitative results of the actuarial calculations may be applied in the shaping the public pension policy when

  14. Demographic cycles, cohort size, and earnings.

    Science.gov (United States)

    Berger, M C

    1989-05-01

    This article examines whether position in the demographic cycle is an important factor in determining earnings and earnings growth. Earnings equations for white males are estimated by using March Current Population Survey data. Position in the demographic cycle is captured by including both measures of own cohort size and the size of surrounding cohorts in the estimated earnings equations. Position in the demographic cycle matters. Increases in own cohort size lead to flatter earnings profiles, whereas increases in the size of surrounding cohorts are associated with steeper earnings profiles. The net effect is that those who enter the labor market before or after the peak of the demographic cycle start out with lower earnings but experience faster earnings growth. This pattern is uniform across all schooling groups: high school dropouts, high school graduates, those with some college, and college graduates.

    An accountant is a good accountant if in practicing his craft he is superb in handling the numbers. But a good accountant in handling the numbers can use that skill to misstate earnings to cover a multitude of problems with a company's books while staying within the law. So, the notion of a moral or ethical accountant is not the same as the notion of a good accountant. Our general principle would be that to be ethical a person has a responsibility to fulfil one's role or roles, as long as tha...

  18. Gender inequalities from the demographic perspective

    2006-01-01

    Full Text Available The paper analyzes the meaning of the phrase "the woman’s status in the society" that is recognized in demography as an important cultural factor of demographic development and transitional changes. The analysis indicates qualitative shifts in the woman’s status and simultaneously reveals its importance at present, not only in traditional, but also in modern and developed societies. On the other hand, it explains the importance of sex as a biodemographic determinant, and introduces the concept of gender that sheds another light on the concepts of sex and woman’s status in the society and integrates them. Gender regimes that subsume the inferiority of women in public and private social structures are examined from demographic perspective, albeit only in those phenomenological aspects that can be supported by demographic research, theories, and analyses. To this end, the paper analyzes the effects of strengthening gender equalities on the fertility and mortality transitions, the gender’s impact on the population distribution by sex in South Asian countries, and highlights the key role of gender in interpreting certain social and economic structures. It also stresses the establishing of gender equality as an important element of population policies. The global dimension of the patriarchal society is illustrated through a series of examples of demographic phenomena from various societies. Gender regimes underlie all of these phenomena. The paper puts foreword certain theoretical hypotheses about gender inequalities, and finds their connections with demographic behaviors and demographic indicators. Finally, it summarizes the role of demography in gender (inequality research and the demographic perspective of the way and the speed the demographic equality is being established. Demography is seen as an irreplaceable discipline in examining gender inequalities, especially at the global level. With the advance of qualitative methods in demography

Structured population models address heterogeneity due to age, size, or major developmental stages. However, other important sources of demographic heterogeneity, such as genetic variation, spatial heterogeneity in the environment, maternal effects, and differential exposure to stressors, are often not easily measured and hence are modeled as stochasticity.

  20. Social Security Individual Accounts in China: Toward Sustainability in Individual Account Financing

    Directory of Open Access Journals (Sweden)

    Tianhong Chen

    2014-08-01

    Full Text Available China has both mandatory and voluntary individual account pensions that are provided through the government. The experience of China makes a particularly interesting case study concerning the functioning of individual accounts in that its mandatory individual accounts have been defunded to pay for benefits in the associated pay-as-you-go system, while its voluntary individual accounts are fully funded. This paper examines three questions. First, it analyses why the mandatory individual accounts have become defunded and converted largely to notional accounts generally holding little in financial assets, while the voluntary accounts have been fully funded. Second, it examines the merits of funding versus pay-as-you-go financing of pensions in the context of China’s economic and demographic situation. Third, it discusses a policy change to insure the sustainability of financing for the defunded individual accounts. The experience of China, with its two types of individual accounts, and with different outcomes for those accounts, may provide lessons for other countries.

    Full Text Available The words and phrases swop with each other and the apparent stability of a word’s meaning sometimes change in time. This explains why the generic term of accounting is used when referring to the qualities attributed to accounting,but also when it comes to organizing financial accounting function within the entity, and when referring concretely to keeping a double record with its specific means, methods and tools specific, respectively seen as a technical accounting.Speaking about the qualities of accounting, but also about the organizational form it takes, we note that there is a manifold meaning of the word accounting, which is why the purpose of this article is to demonstrate that the paradigm shift aimed at a new set of rules and if the rules changes, then we can change the very purpose of accounting.

    The rationale behind screening for atrial fibrillation (AF) is to prevent ischemic stroke. Socio-demographic differences are expected to affect screening uptake. Geographic differences may provide further insights leading to targeted interventions for improved uptake. The objective of this study was to evaluate geographic and socio-demographic differences in uptake of AF screening in the population-based study STROKESTOP I. STROKESTOP was carried out in two Swedish counties with a total population of 2.3 million inhabitants. Half of the residents aged 75-76years were randomized to the screening arm: invitation to clinical examination followed by ambulant ECG recording. Information on each invited person's residential parish (n=157) was used. On parish-level, aggregated data for the participants and non-participants, respectively, were obtained with respect to socioeconomic variables: educational level, disposable income, immigrant and marital status. Geo-maps displaying participation ratios were estimated by hierarchical Bayes methods. The overall participation rate was similar in men and women but lower in Stockholm, 47.6% (5665/11,903) than in Halland, 61.2% (1495/2443). Participation was clearly associated with the socioeconomic variables. Participation not taking into account socioeconomy varied more markedly across the parishes in the Stockholm county (range: 0.65-1.26) than in the Halland county (0.94-1.27). After adjustment for socioeconomic variables, a geographic variation remained in Stockholm, but not in Halland. Participation in AF screening varied according to socioeconomic conditions. Geographic variation in participation was marked in the Stockholm county, with only one screening clinic. Geo-mapping of participation yielded useful information needed to intervene for improved screening uptake. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

  4. Two centuries of demographic change in Canada

    Barry Edmonston

    2014-03-01

    Full Text Available One key aspect of the demographic transition—the shift from high mortality and high fertility to low mortality and low fertility is a major change in the population’s age distribution from a pyramid-shaped young age structure to a pillar-shaped old age structure. This paper discusses two demographic processes affected by changes in age structure. First, there are effects on vital rates, with important differences in the observed crude rates and the implied intrinsic vital rates. Second, changes in age structure influence population momentum. More recently, demographers have noted that older age distributions associated with fertility levels below replacement have negative population momentum. Although the demographic transition has been well-described for many countries, demographers have seldom analyzed intrinsic vital rates and population momentum over time, which are dynamic processes affected by changes in the population age structure and which, in turn, influence future changes in population growth and size. This paper uses new data and methods to analyze intrinsic vital rates and population momentum across two centuries of demographic change in Canada

    Full Text Available Major worldwide demographic trends impact significantly each aspect of people’s lives. The impact will be favorable for some states and completely unfavorable for others since they will depend not only on the magnitude of these tendencies, but also on the aggregated result of the inherent shifts and developments at political, economic, social and military level Global demographic trends will represent a genuine challenge for the powerful states to maintain the existing global political and economic equilibrium and they will also constitute a genuine shocking force for international security and stability. At the same time, they will represent one of the variables underpinning states’ strategies, and domestic and foreign policies and influencing political and military alliances in the future. It is likely that they will lead to the reassessment of the bases of international relations. This paper analyzes the presumed consequences of future demographic shifts on the economic, political, military field and proposes some possible solutions to efficiently manage the issue.

    Full Text Available Abstract Background The rate of total edentulism is said to be increasing in developing countries and this had been attributed mainly to the high prevalence of periodontal diseases and caries. Several reports have shown that non-disease factors such as attitude, behavior, dental attendance, characteristics of health care systems and socio-demographic factors play important roles in the aetiopathogenesis of edentulism. The aim of this study was to assess the relationship between socio-demographic factors and edentulism. Methods A total of 152 patients made up of 80 (52.6% males and 72 (47.4% females who presented in two prosthetic clinics located in an urban and a rural area were included in the study. The relationship between gender, age, socio-economic status and edentulism in this study population was established. Results No significant relationship between gender and denture demand was noted in the study. The demand for complete dentures increased with age while the demand for removable partial dentures also increased with age until the 3rd decade and then started to decline. A significant relationship was found between denture demand and the level of education with a higher demand in lower educational groups (p Conclusions The findings in this study revealed a significant relationship between socio-demographic variables and edentulism with age, educational level and socio-economic status playing vital roles in edentulism and denture demand.

    Objectives The aim of this study was to study the demographics of feline hip dysplasia (FHD) in the Maine Coon cat. Methods The complete hip dysplasia registry (public and private) collected by the Orthopedic Foundation for Animals through April 2015 was accessed. There were 2732 unique cats; 2708 (99.1%) were Maine Coons, and only these were studied. Variables analyzed were sex, month/season of birth and hip dysplasia score. Two groups were created: those with and without FHD. P dysplasia were older. The percentage of bilateral FHD was 56%, and bilateral cases had more severe dysplasia than unilateral cases but with no age difference. Month/season of birth or geographic region of origin did not influence the prevalence of FHD. Conclusions and relevance This is the largest demographic study of FHD in the Maine Coon cat. The overall prevalence in the Orthopedic Foundation for Animals registry was 24.9%, and slightly higher in males (27.3%) than females (23.3%). Dysplasia was more severe in bilateral than unilateral cases and with increasing age. Caution should be used when extrapolating these findings to other feline breeds or other groups of Maine Coon cats. Further studies need to be performed among other breeds and geographic locations to better understand the demographics of feline hip dysplasia.

    Full Text Available The aim of the present study is to examine personality traits and self-esteem levels of a total number of 124 adolescents aging between 14 and 20 (62 adolescents who are using substance and 62 adolescents who are not using any substance are compared based on certain socio-demographic variables. Five-Factor Personality Inventory (FFPI and Rosenberg Self-Esteem Questionnaire (RSEQ are used in order to collect data. For the comparison of two groups, t-test is used if the data was normally distributed, and Mann-Whitney U Test was used when normality assumptions were not met. When there are more than two groups, for normally distribute variables One-way ANOVA, and when normality assumptions were not met, Kruskal-Wallis Test were used. According to the findings, girls who are using substance had lower levels of conscientiousness compared to girls who are not using any substance. For boys, they had lower scores for extraversion, agreeableness, conscientiousness, and openness to experience and higher levels of neuroticism if they are using some substance compared to the ones who are not using any substance. When age is taken into consideration, the results indicated that substance using adolescents between 17-20 had higher agreeableness scores compared to the substance using adolescents aged between 14-16. On the other hand, no significant differences were found for adolescents who are not using any substance. Moreover, there were not any significant differences based on the age onset of substance use and immigration status. For self-esteem, boys who are using substance had lower levels compared to the boys who are not using substance. There was no significant difference for the girls based on self-esteem. Results were discussed in the light of literature and implications were proposed.    Özet Bu çalışmada, 14-20 yaş arasında, 62 madde kullanan ve 62 madde kullanmayan olmak üzere toplam 124 ergenin kişilik özellikleri ile benlik saygısı d

METHODS: The sample consisted of 728 children attending 22 public (n=428 and 18 private (n=300 preschools. Dental caries were measured using the dmft/dmfs indexes and by detecting initial caries lesion (IL. Gingivitis, crowding, spacing, fluorosis, and mouth breathing were also recorded. Socioeconomic variables (monthly family income, number of people living in the household, parents' schooling, home ownership, and car ownership were collected by means of a parental semi structured questionnaire. RESULTS: The mean (standard deviation values for dmft and dmfs indexes were 1.30 (2.47 and 3.08 (7.55 respectively; and 62.2% of the children were caries-free. The mean (standard deviation values for dmft+LI and dmfs+LI were 1.72 (3.36 and 3.45 (7.94, respectively and 59.7% were caries-free. By means of multiple logistic regression analyses, children with fluorosis (OR=0.40 or family income > 4 minimum wages (OR=0.49 were less likely to experience caries. Those with gingivitis (OR=1.87 were more prone to have the disease. Considering the diagnostic threshold including IL, the multiple logistic regression analyses showed that children with fluorosis (OR=0.39 or family income > 4 minimum wages (OR=0.52 were less likely to have caries. Those with gingivitis (OR=1.80, crowding (OR=2.63 e OR=1.01 or mouth breathing (OR=1.37 were more likely to have the disease. CONCLUSION: The preschool children who presented gingivitis, crowding, mouth breathing or monthly family income < 4 minimum wages were more likely to experience caries. In this way, planning preventive and operative actions targeted at these children would be essential for caries control.

  10. Regulation of the demographic structure in isomorphic biphasic life cycles at the spatial fine scale.

    Vasco Manuel Nobre de Carvalho da Silva Vieira

    Full Text Available Isomorphic biphasic algal life cycles often occur in the environment at ploidy abundance ratios (Haploid:Diploid different from 1. Its spatial variability occurs within populations related to intertidal height and hydrodynamic stress, possibly reflecting the niche partitioning driven by their diverging adaptation to the environment argued necessary for their prevalence (evolutionary stability. Demographic models based in matrix algebra were developed to investigate which vital rates may efficiently generate an H:D variability at a fine spatial resolution. It was also taken into account time variation and type of life strategy. Ploidy dissimilarities in fecundity rates set an H:D spatial structure miss-fitting the ploidy fitness ratio. The same happened with ploidy dissimilarities in ramet growth whenever reproductive output dominated the population demography. Only through ploidy dissimilarities in looping rates (stasis, breakage and clonal growth did the life cycle respond to a spatially heterogeneous environment efficiently creating a niche partition. Marginal locations were more sensitive than central locations. Related results have been obtained experimentally and numerically for widely different life cycles from the plant and animal kingdoms. Spore dispersal smoothed the effects of ploidy dissimilarities in fertility and enhanced the effects of ploidy dissimilarities looping rates. Ploidy dissimilarities in spore dispersal could also create the necessary niche partition, both over the space and time dimensions, even in spatial homogeneous environments and without the need for conditional differentiation of the ramets. Fine scale spatial variability may be the key for the prevalence of isomorphic biphasic life cycles, which has been neglected so far.

  11. [Demographic projections for Latin American countries prepared by CELADE].

    Somoza, J L

    1978-04-01

    The CELADE (Centro Latinoamericano de Demografia) prepares population projections for 20 Latin American countries, a difficult task considering the lack of reliable census data on births, deaths, and other demographic information. Nevertheless, the demographic situation can be estimated by distinguishing two states in the process: estimating past and present population history and formulating hypotheses regarding the future trends of demographic variables. In a typical situation for most Latin American countries, the first stage is the most difficult; results are mostly approximations of the reality. Thus, projections based on these data are unreliable. The present demographic situation in Latin America was analyzed by estimating fertility, mortality and international migration. Fertility rate was calculated based on the following data: number of children born to the female population, number of live births during the year prior to the census classified according to mother's age and number of children registered according to age up to 10 or 15 years of age. Fertility was thus calculated within 5 years prior to the census. Mortality was roughly estimated by calculating the annual death distribution by age. This promoted questions relating to orphans and the relative number of children who survived out of total number of children born to a woman. Little data was available on migration due to lack of registries on annual migration. It was estimated based on the number of people who left the country for 5 years, and promoted questions such as which country is one native of and year of entry into the country. The most important task relating to population projection of Latin America is the improvement of knowledge on fertility, mortality and migration.

    Full Text Available Introduction: Comparison of the demographic characteristics of patients provides useful information to their identification. This study aimed to determine the demographic characteristics of children and adolescents with autistic disorder (AD. Methods: In this cross-sectional case-control study, 115 children and adolescents with AD were selected from Autism Society Rehabilitation Center in Tabriz, Iran, and 112 normal children and adolescents from the public schools, in 2014. The participants in both groups were matched regarding age and gender. Diagnosis of AD was performed using diagnostic and statistical manual of mental disorders-4th edition (DSM-IV criteria and clinical diagnostic interviews by two child and adolescent psychiatrists. The demographic information of children and adolescents and their parents were collected from the medical records of children and interviews with their mothers. Results: Most of the children with autism had second or higher birth order and had families with more than three members. Mothers of children with autism had significantly lower levels of education and were mostly housewives. Fathers of autistic children mostly had high school diploma and fewer had university education, and most of them were employed. However, there was no statistically significant difference between the AD group and the control group regarding the average height and weight of children and the residence (urban or rural and age of parents at childbirth.Conclusion: The demographic characteristics of the two groups of children and adolescents with AD and normal controls were different from each other regarding family size, birth order, parent occupation, and parent education variables.

    2010-12-01

    A new model for lease accounting can have a significant impact on hospitals and healthcare organizations. The new approach proposes a "right-of-use" model that involves complex estimates and significant administrative burden. Hospitals and health systems that draw heavily on lease arrangements should start preparing for the new approach now even though guidance and a final rule are not expected until mid-2011. This article highlights a number of considerations from the lessee point of view.

How strong the commitment to goals is depends on the type of psychological account. We provide conditions when it is optimal to evaluate goals in narrow accounts. The key intuition......We model how people formulate and evaluate goals to overcome self-control problems. People often attempt to regulate their behavior by evaluating goal-related outcomes separately (in narrow psychological accounts) rather than jointly (in a broad account). To explain this evidence, our theory...... of endogenous narrow or broad psychological accounts combines insights from the literatures on goals and mental accounting with models of expectations-based reference-dependent preferences.

    Full Text Available The multistate life table (MSLT model is an important demographic method to document life cycle processes. In this study, we present the SPACE (Stochastic Population Analysis for Complex Events program to estimate MSLT functions and their sampling variability. It has several advantages over other programs, including the use of microsimulation and the bootstrap method to estimate the sampling variability. Simulation enables researchers to analyze a broader array of statistics than the deterministic approach, and may be especially advantageous in investigating distributions of MSLT functions. The bootstrap method takes sample design into account to correct the potential bias in variance estimates.

  18. The Accountability Bind

    Full Text Available Charter schools involve a trading of autonomy for accountability. This accountability comes through two forces—markets through the choices of parents and students, and accountability to government through the writing of contracts that must be renewed for schools to continue to operate. Charter schools are supposed to be more accountable for educational performance than traditional public schools because authorizers have the ability to revoke charter contracts. Here, I focus on one central component of accountability to government: performance accountability or accountability for educational outcomes to charter school authorizers through the revocation or non-renewal of charter contracts. In this paper, I suggest that contract-based accountability for educational performance in charter schools may not be working as proponents argued it would. This article explores some explanations for why there are very few examples of charter schools that have been closed primarily because of failure to demonstrate educational performance or improvement. Future work will need to test if these challenges for authorizers hold in a variety of contexts. The conclusion examines the implications of these findings for the future of charter school accountability.

    Previous research has investigated the characteristics of competent and incompetent defendants and restorable and nonrestorable defendants. However, less is known about the influence of current treatment variables and other systemic factors on restorability. In the present study, we sought to examine the impact of demographic, criminogenic, historical clinical, and current treatment variables on the restorability and length of stay (LOS) of incompetent defendants. We reviewed the records of 71 male patients who had been court ordered for competency restoration and subsequently discharged from a maximum-security forensic hospital. Results indicated that nonrestorable patients had more prior hospitalizations, incarcerations, and episodes of incompetence, had lower level charges, were diagnosed with a psychotic and cognitive disorder, were prescribed more medications, and had lower global assessment of functioning (GAF) scores. Nonrestorable patients were hospitalized nearly twice as long as those eventually found competent, and patients with lower IQs and lower GAFs and who spent more days on special observations had longer LOS.

    2014-08-01

    Full Text Available Background: Professional burnout results from prolonged exposure to chronic, job-related stressors. According to Christina Maslach, professional burnout is a syndrome of emotional exhaustion, depersonalization and reduced personal accomplishment. Literature includes a number of reports on burnout syndrome within health service, but hardly ever do they make any references to physiotherapists. The purpose of this study is assessment of the level of professional burnout in a group of physiotherapists and investigating relationships between the indices of burnout syndrome and selected demographic as well as organizational variables. Material and Methods: The study group consisted of 151 physiotherapists with at least 3 years of experience, employed in various health service outposts in Krakow, Poland. The Maslach Burnout Inventory (MBI was used to measure emotional exhaustion, depersonalization and personal accomplishment. A questionnaire for the description of socio-demographic and work characteristics was used as well. Results: Job burnout among the physiotherapists was manifested by an increased emotional exhaustion and decreased sense of personal achievement. Emotional exhaustion was significantly higher among physical therapists working with adults and employed in hospitals, depersonalization was higher among men, hospital workers and employees with seniority from 15 to 19 years, personal accomplishment was decreased among men and less-educated therapists. Conclusions: The study confirmed that indicators of burnout in physiotherapists are significantly associated with selected demographic and organizational variables. It is necessary to undertake a more exhaustive study of burnout in this group of employees, and implement elements of prevention. Med Pr 2014;65(4:453–462

    The aim of this study was to explore the relationship between socio-demographic characteristics and the level of complementary and supplementary person-organization fit (P-O fit). The study sample was a group of 600 Polish workers, urban residents aged 19-65. Level of P-O fit was measured using the Subjective Person-Organization Fit Questionnaire by Czarnota-Bojarska. The binomial multivariate logistic regression was applied. The analyzes were performed separately for the men and women. Socio-demographic variables explained small percentage of the outcome variability. Gender differences were found. In the case of men shift work decreased complementary and supplementary fit, while long working hours decreased complementary fit. In the women, age was a stimulant of a complementary fit, involuntary job losses predicted both complementary and supplementary misfit. Additionally, relational responsibilities increased probability of supplementary P-O fit in the men. Going beyond personality and competences as the factors affecting P-O fit will allow development of a more accurate prediction of P-O fit. Int J Occup Med Environ Health 2017;30(1):133-139.

  5. Analyzing the Impact of Residential Building Attributes, Demographic and Behavioral Factors on Natural Gas Usage

    Energy Technology Data Exchange (ETDEWEB)

    Livingston, Olga V.; Cort, Katherine A.

    2011-03-03

    This analysis examines the relationship between energy demand and residential building attributes, demographic characteristics, and behavioral variables using the U.S. Department of Energy’s Residential Energy Consumption Survey 2005 microdata. This study investigates the applicability of the smooth backfitting estimator to statistical analysis of residential energy consumption via nonparametric regression. The methodology utilized in the study extends nonparametric additive regression via local linear smooth backfitting to categorical variables. The conventional methods used for analyzing residential energy consumption are econometric modeling and engineering simulations. This study suggests an econometric approach that can be utilized in combination with simulation results. A common weakness of previously used econometric models is a very high likelihood that any suggested parametric relationships will be misspecified. Nonparametric modeling does not have this drawback. Its flexibility allows for uncovering more complex relationships between energy use and the explanatory variables than can possibly be achieved by parametric models. Traditionally, building simulation models overestimated the effects of energy efficiency measures when compared to actual "as-built" observed savings. While focusing on technical efficiency, they do not account for behavioral or market effects. The magnitude of behavioral or market effects may have a substantial influence on the final energy savings resulting from implementation of various energy conservation measures and programs. Moreover, variability in behavioral aspects and user characteristics appears to have a significant impact on total energy consumption. Inaccurate estimates of energy consumption and potential savings also impact investment decisions. The existing modeling literature, whether it relies on parametric specifications or engineering simulation, does not accommodate inclusion of a behavioral component. This

    2013-06-01

    Full Text Available Accounting professionals, business college accrediting bodies, and even accounting academics themselves acknowledge that there is a disconnect between academe and the rigors and requirements of the accounting profession. Among the suggestions proposed in the literature to reduce this gap is the faculty internship, where accounting faculty members work within the field as accountants. Heretofore, individual case studies report benefits of such internships that accrue to a variety of stakeholder groups beyond just the faculty intern and include the academic institution, students, and accounting profession through faculty internships. This research seeks wider support for these benefits. This descriptive study involved surveying a sample of accounting faculty members to get their opinions about the benefits and drawbacks of faculty internships, and to determine the level of use of faculty internships in accounting. In all, 128 usable responses were obtained, representing a 14.6% response rate. The results of this study reveal that although most faculty members acknowledge the benefits cited in the literature, too few take advantage of faculty internships.

  5. Simulating Residential Demand in Singapore through Five Decades of Demographic Change

    Science.gov (United States)

    Davis, N. R.; Fernández, J.

    2011-12-01

    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

    1989-01-01

    Anthropologists, geneticists, and epidemiologists need clear and detailed descriptions of the demographic situation of the populations they study in order to stratify their samples and calculate their degrees of significance as well as to evaluate the impact of particular traits on their field of investigation. Census and other available demographic data are usually not sufficiently precise, especially in illiterate populations. Establishing the genealogies of all families, conducting a census of all residents to verify and complete the genealogies, and designing 1 or more specific surveys of fertility, marriage, infant mortality, migration, or other topics are recommended to satisfy the needs of a multidisciplinary research team. Data collection is the most delicate phase of a demographer's work. The quality of contacts with the study population will determine response rates and the efforts of the population to give exact and precise information. Establishment of genealogies requires a good knowledge of the kinship system and the exact meaning of kinship terms. Surveys will be necessary to establish fertility and mortality rates, which will be greatly underestimated by the genealogies and census. Specific surveys may be retrospective, prospective, or a combination, depending on available time and budget. In addition to the classic omissions that are often increased in illiterate populations by lapses of memory, the problems may arise of misunderstanding of demographic concepts and tabus against reporting of certain events or practices or against directly mentioning certain names such as those of deceased husbands. Variables lending themselves to misunderstanding and false interpretations may include such socioeconomic features as principal occupation, educational level, marital status, and even age. The greatest source of error in a demographic analysis not based on a reliable civil registration system is undoubtedly omission, some of which is voluntary and not

  8. Association between Maternal and Child Dietary Diversity: An Analysis of the Ghana Demographic and Health Survey.

    Full Text Available This study examined the association between maternal and child dietary diversity in a population-based national sample in Ghana.The data for this analysis are from the 2008 Ghana Demographic and Health Survey. We used data obtained from 1187 dyads comprised of mothers' ages 15-49 and their youngest child (ages 6-36 months. Maternal and child dietary diversity scores (DDS were created based on the mother's recall of her own and her child's consumption of 15 food groups, during the 24 hours prior to the in-home survey. The same food groups were used to compose both maternal and child DDS. Linear regression was used to assess the relationship between the predicted outcome--child DDS--and maternal DDS, taking into account child age and sex, maternal factors (age, education, occupation, literacy, empowerment, number of antenatal visits as an indicator of health care use, household Wealth Index, and urban/rural place of residence.There was a statistically significant positive association between child and maternal DDS, after adjusting for all other variables. A difference of one food group in mother's consumption was associated with a difference of 0.72 food groups in the child's food consumption (95% CI: 0.63, 0.82. Also, statistically significant positive associations were observed such that higher child DDS was associated with older child age, and with greater women's empowerment.The results show a significant positive association between child and maternal DD, after accounting for the influence of child, maternal and household level factors. Since the likely path of influence is that maternal DDS impacts child DDS, public health efforts to improve child health may be strengthened by promoting maternal DDS due to its potential for a widened effect on the entire family.

    The development accounting literature almost always assumes a Cobb-Douglas (CD) production function. However, if in reality the elasticity of substitution between capital and labor deviates substantially from 1, the assumption is invalid, potentially casting doubt on the commonly held view...... that factors of production are relatively unimportant in accounting for differences in labor productivity. We use international data on relative factor shares and capital-output ratios to formulate a number of tests for the validity of the CD assumption.

He then examines the need of organizations to improve safety performance, discusses why such performance improvement can be achieved through a continuous safety process, as distinguished from a safety program, and provides the practic

  12. The neolithic demographic transition in Europe: correlation with juvenility index supports interpretation of the summed calibrated radiocarbon date probability distribution (SCDPD as a valid demographic proxy.

    Sean S Downey

    Full Text Available Analysis of the proportion of immature skeletons recovered from European prehistoric cemeteries has shown that the transition to agriculture after 9000 BP triggered a long-term increase in human fertility. Here we compare the largest analysis of European cemeteries to date with an independent line of evidence, the summed calibrated date probability distribution of radiocarbon dates (SCDPD from archaeological sites. Our cemetery reanalysis confirms increased growth rates after the introduction of agriculture; the radiocarbon analysis also shows this pattern, and a significant correlation between both lines of evidence confirms the demographic validity of SCDPDs. We analyze the areal extent of Neolithic enclosures and demographic data from ethnographically known farming and foraging societies and we estimate differences in population levels at individual sites. We find little effect on the overall shape and precision of the SCDPD and we observe a small increase in the correlation with the cemetery trends. The SCDPD analysis supports the hypothesis that the transition to agriculture dramatically increased demographic growth, but it was followed within centuries by a general pattern of collapse even after accounting for higher settlement densities during the Neolithic. The study supports the unique contribution of SCDPDs as a valid demographic proxy for the demographic patterns associated with early agriculture.

    Full Text Available Health care systems face pressure to increase the quality of health care at the same time with pressure to reduce public spending. The attempt to overcome the gap between needs and opportunities can be resolved through the introduction of public-private partnerships. Goals of this study are to investigate variation of the number, form and efficiency of private providers of general/family medicine services in primary health care and the contribution of socioeconomic and demographic environment on those variations, among counties. Socioeconomic and demographic factors are identified as independent variables that influence the health care need and utilization and consequently the decision of private entities to engage in the provision of health care services. This study extended previous studies because it has introduced socioeconomic and demographic variables. This may shed same new lights on the relationship between private providers of health service and efficiency of providing health service in primary health care.

Descriptive comparative approach was used in result analysis. The Father Presence Questionnaire and Marital Satisfaction Questionnaire were used, in addition to a number of demographic variables. Results showed that only physical relationship with the father, and perceptions of father’s influence, had a positive significant impact on wives’ marital satisfaction. Of all domains, only positive feelings about the father had a negative impact on the husband's marital satisfaction. Most demographic variables had statistically significant effect on marital satisfaction. Sociocultural implications for marital satisfaction for wives and husbands are discussed. Keywords: early father–daughter relationship, demographic, spousal marital satisfaction

    Full Text Available The text is re-examining the previously established dilemma related to whether Serbia (without Kosovo and Metohija is the country of second demographic transition, i.e.: has the transition been de-blocked, under the assumption that this is a worldwide historical process of transformation of industrialized countries. The last thesis, around which there exists a lot of controversy in the contemporary population theory, is however not dealt with in detail; to the contrary, it is used as the general theoretical framework for the exploration of the most recent tendencies in the transformation of nuptiality and fertility regime in Serbia, as well as in the western and countries in post-socialist transformation. Special attention is given to the ideational changes, more precisely to the specific features of the value profile of the Serbian population, which is one of the most important determinants of the societal framework, that acts in the back of the afore mentioned aggregate demographic indicators. Finally, the hypothesis is posed (which should be further investigated by means of in-depth research and complementary approach that the speeding-up of the second demographic transition and intensification of the individualisation not only of the partnership but of the parenthood as well, accompanied with the rise of living standard and social support to balancing work and family, would have produced important emancipating and, concomitantly, positive socioeconomic and demographic effects.

    Full Text Available This paper deals with the economic and financial valuation, that is the only type of valuation, based on a diagnosis and expertise, which has as objective to establish the market value of elements, whether goods or businesses, being a "orientation tool" for the economic operators on the market. There are specific means to measure value but there are also some mechanisms that can influence the value obtained, from the category of creative accounting. Creative accounting occurs due to human intervention and even the most advanced accounting systems are not able to do this due to the lack of reasoning. There must be also assumed that it is possible that these creative accounting techniques may be caused by a simple mistake and not necessarily with the intention of manipulating the financial results and reports. The aim of the paper is to see how specific element valuation can influence the general one, namely the value of a company.

  19. Illuminating Free-floating Planet Demographics with Keck AO

    Science.gov (United States)

    Henderson, Calen B.

    2017-01-01

    The frequency and mass function of free-floating planets (FFPs) are unknown. Gravitational microlensing is able to explore the demographics of FFPs, which are identifiable as short-timescale microlensing events, lasting of-order 1 day for Jupiter-mass planets. In 2011, the MOA ground-based microlensing survey group announced the discovery of an excess of short-timescale microlensing events over what was expected from Galactic models that incorporate stellar densities and kinematics. They account for this excess by positing a population of Jupiter-mass FFPs that outnumbers stars by a ratio of nearly 2:1. However, there are several other possible astrophysical explanations for short-timescale microlensing events, including bound planets on wide orbits and high-velocity stars. Although the specific events identified by MOA lack mass measurements, high-resolution imaging can determine whether the lens systems are luminous, which would exclude the FFP conclusion through proof by contradiction. We have taken H-band adaptive optics (AO) observations of the MOA FFP candidates using NIRC2 on Keck II in order to test this result. Here I will present preliminary results from these AO observations, which will help inform our understanding of the demographics of FFPs.

    2016-04-19

    The role that social status plays in small-scale societies suggests that status may be important for understanding the evolution of human fertility decisions, and for understanding how such decisions play out in modern contexts. This paper explores whether modelling competition for status--in the sense of relative rank within a society--can help shed light on fertility decline and the demographic transition. We develop a model of how levels of inequality and status competition affect optimal investment by parents in the embodied capital (health, strength, and skills) and social status of offspring, focusing on feedbacks between individual decisions and socio-ecological conditions. We find that conditions similar to those in demographic transition societies yield increased investment in both embodied capital and social status, generating substantial decreases in fertility, particularly under conditions of high inequality and intense status competition. We suggest that a complete explanation for both fertility variation in small-scale societies and modern fertility decline will take into account the effects of status competition and inequality. © 2016 The Author(s).

    2015-01-01

    Drawn on the data col ected by surveying 1 340 urban households from six cities in China, this paper estimates the impacts of demographic structure and population aging on household meat consumption, by jointly considering meat consumed at home and away from home. Based on the trajectories of population, a simple simulation on meat demand trend in China is conducted subsequently. The results suggest:1) Meat consumed away from home averagely accounts for near 30%of household total meat consumption in terms of quantity, so that its omission likely leads to a signiifcant underestimate of total meat consumption and misunderstanding the driving forces;2) population aging signiifcantly and negatively affects per capita meat consumption, suggesting that the expected meat demand in China without considering population aging wil be overestimated. The ifndings from this study have important implications for better understanding the relative issues on China’s meat consumption under the situation of population aging.

    The demographic features, treatment, and outcome of 36 rattlesnake envenomation cases are reviewed. Two populations at special risk are identified: (1) young children (12/36) who sustain lower extremity bites, and (2) adults who consume alcohol and handle snakes (10/36) who sustain upper extremity bites. Antivenin was used in 22 cases with only one serious case of serum sickness. Three definite diagnoses of compartment syndrome were made on the basis of elevated compartment pressures. Hand bites accounted for 20 of the 36 cases. The greatest functional disability followed digit bites in that 11 patients developed decreased motion and sensation. The indications for fasciotomy and debridement are discussed, both for digit and non-digit envenomations. General treatment recommendations are given.

    2011-09-01

    Full Text Available Objective: To investigate the impact of various bio-demographic and socio-economic variables on joint childhood diseases in Nigeria with flexible geoadditive probit models. Methods: Geoadditive latent variable model (LVM was applied where the three observable disease (diarrhea, cough, fever variables were modelled as indicators for the latent individual variable "health status" or "frailty" of a child. This modelling approach allowed us to investigate the common influence of risk factors on individual frailties of children, thereby automatically accounting for association between diseases as indicators for health status. The LVM extended to analyze the impact of risk factors and the spatial effects on the unobservable variable “health status ” of a child less than 5 years of age using the 2003 Demographic and Health Surveys (DHS data for Nigeria. Results: The results suggest some strong underlying spatial patterns of the three ailments with a clear southeastern divide of childhood morbidities and this might be the results in the overlapping of the various risk factors. Conclusions: Comorbidity with conditions such as cough, diarrhoea and fever is common in Nigeria. However, little is known about common risk factors and geographical overlaps in these illnesses. The search for overlapping common risk factors and their spatial effects may improve our understanding of the etiology of diseases for efficient and cost-effective control and planning of the three ailments.

    2017-08-01

    Too much sitting (extended sedentary time) is recognized as a public health concern in Europe and beyond. Time spent sedentary is influenced and conditioned by clusters of individual-level and contextual (upstream) factors. Identifying population subgroups that sit too much could help to develop targeted interventions to reduce sedentary time. We explored the relative importance of socio-demographic correlates of sedentary time in adults across Europe. We used data from 26,617 adults who participated in the 2013 Special Eurobarometer 412 "Sport and physical activity". Participants from all 28 EU Member States were randomly selected and interviewed face-to-face. Self-reported sedentary time was dichotomized into sitting less or >7.5h/day. A Chi-squared Automatic Interaction Detection (CHAID) algorithm was used to create a tree that hierarchically partitions the data on the basis of the independent variables (i.e., socio-demographic factors) into homogeneous (sub)groups with regard to sedentary time. This allows for the tentative identification of population segments at risk for unhealthy sedentary behaviour. Overall, 18.5% of the respondents reported sitting >7.5h/day. Occupation was the primary discriminator. The subgroup most likely to engage in extensive sitting were higher educated, had white-collar jobs, reported no difficulties with paying bills, and used the internet frequently. Clear socio-demographic profiles were identified for adults across Europe who engage in extended sedentary time. Furthermore, physically active participants were consistently less likely to engage in longer daily sitting times. In general, those with more indicators of higher wealth were more likely to spend more time sitting. Copyright © 2017 The Author(s). Published by Elsevier Inc. All rights reserved.

    Elderly populations have a higher risk of rib fractures and other associated thoracic injuries than younger adults, and the changes in body morphology that occur with age are a potential cause of this increased risk. Rib centroidal path geometry for 20 627 ribs was extracted from computed tomography (CT) scans of 1042 live adult subjects, then fitted to a six-parameter mathematical model that accurately characterizes rib size and shape, and a three-parameter model of rib orientation within the body. Multivariable regression characterized the independent effect of age, height, weight, and sex on the rib shape and orientation across the adult population, and statistically significant effects were seen from all demographic factors (P rib end-to-end separation and rib aspect ratio are seen to increase with age, producing elongated and flatter overall rib shapes in elderly populations, with age alone explaining up to 20% of population variability in the aspect ratio of mid-level ribs. Age was not strongly associated with overall rib arc length, indicating that age effects were related to shape change rather than overall bone length. The rib shape effect was found to be more strongly and directly associated with age than previously documented age-related changes in rib angulation. Other demographic results showed height and sex being most strongly associated with rib size, and weight most strongly associated with rib pump-handle angle. Results from the study provide a statistical model for building rib shapes typical of any given demographic by age, height, weight, and sex, and can be used to help build population-specific computational models of the thoracic rib cage. Furthermore, results also quantify normal population ranges for rib shape parameters which can be used to improve the assessment and treatment of rib skeletal deformity and disease. © 2017 Anatomical Society.

    The first part of this article consists in attempting to highlight the importance of concerning about the economic consequences and introducing the foundation of economic consequence theory, proposing that the accounting standard is not only a kind of technical standard, it also has the economic consequences, so it becomes the object which all quarters special interest group gambles to get latent profit. After general characterization of the economic consequences in the second part, the article gives a description of the influences the change of accounting standards bring to the government, the ordinary investors and creditors, the auditors, and the enterprise, establishing a framework that how those groups react as the economic consequences in the third part. The fourth section compare technical theory and accounting standards theory, links the basic norms of accounting such as conservatism, relevance and reliability to the methods of escaping the harm of economic consequences, then proposes some specific methods in the formuhtion of accounting standard. Finally, the article utilizes the methods to settle the problems appearing in Chinese market.

  15. Demographic analysis from summaries of an age-structured population

    Demographic analyses of age-structured populations typically rely on life history data for individuals, or when individual animals are not identified, on information about the numbers of individuals in each age class through time. While it is usually difficult to determine the age class of a randomly encountered individual, it is often the case that the individual can be readily and reliably assigned to one of a set of age classes. For example, it is often possible to distinguish first-year from older birds. In such cases, the population age structure can be regarded as a latent variable governed by a process prior, and the data as summaries of this latent structure. In this article, we consider the problem of uncovering the latent structure and estimating process parameters from summaries of age class information. We present a demographic analysis for the critically endangered migratory population of whooping cranes (Grus americana), based only on counts of first-year birds and of older birds. We estimate age and year-specific survival rates. We address the controversial issue of whether management action on the breeding grounds has influenced recruitment, relating recruitment rates to the number of seventh-year and older birds, and examining the pattern of variation through time in this rate.

  16. Germ banks affect the inference of past demographic events.

    2012-11-01

    Continuous progress in empirical population genetics based on the whole-genome polymorphism data requires the theoretical analysis of refined models in order to interpret the evolutionary history of populations with adequate accuracy. Recent studies focus prevalently on the aspects of demography and adaptation, whereas age structure (for example, in plants via the maintenance of seed banks) has attracted less attention. Germ banking, that is, seed or egg dormancy, is a prevalent and important life-history trait in plants and invertebrates, which buffers against environmental variability and modulates species extinction in fragmented habitats. Within this study, we investigate the combined effect of germ banking and time-varying population size on the neutral coalescent and particularly derive the allele frequency spectrum under some simplifying assumptions. We then perform an ABC analysis using two simple demographic scenarios-a population expansion and an instantaneous decline. We demonstrate the appreciable influence of seed banks on the estimation of demographic parameters depending on the germination rate with biases scaled by the square of the germination rate. In the more complex case of a population bottleneck, which comprises an instantaneous decline and an expansion phase, ignoring information on the germination rate denies reliable estimates of the bottleneck parameters via the allelic spectrum. In particular, when seeds remain in the bank over several generations, recent expansions may remain invisible in the frequency spectrum, whereas ancient declines leave signatures much longer than in the absence of seed bank.

    Objective : Orofacial clefts such as cleft lip, cleft palate, and cleft lip and palate are the most frequent congenital anomalies of the head and neck. The purpose of this study was to determine the current demographics for orofacial clefts in Canada. Methods : A request for data from all Canadian provinces (excluding Quebec due to incompatibilities with provincial coding systems) for the fiscal years 2002-2003 to 2007-2008 was submitted to the Canadian Institute for Health Information. Variables evaluated included gender, cleft type, gestational age, birth weight, income quintile, and institution health region. Results : Over the period studied, the prevalence of orofacial clefts ranged from 11.0 to 15.3 per 10,000 live births (1 in 654 to 1 in 909 live births). The distribution of cleft types for live births with orofacial clefts was 17% for cleft lip, 41% for cleft palate, and 42% for cleft lip and palate, of which cleft lip and cleft lip and palate were male dominant (62% and 66% male, respectively) and cleft palate was female dominant (56% female). Saskatchewan and Manitoba had significantly higher cleft birthrates (P orofacial clefting compared with those with no cleft. Conclusions : Canada has one of the highest orofacial cleft birthrates in the world (prevalence of 12.7 per 10,000 live births, approximately 1 in 790 live births). This study presents an updated demographic of orofacial clefts in Canadian newborns and may be useful in predicting the burden of anticipated health care.

    2009-02-01

    Full Text Available In the last three decades worldwide environmental consciousness has increased dramatically as well as profiling green consumers have gained tremendous attention in the past. Segmenting and targeting markets base on pro-environmental purchase behavior are essential when companies positioning their green products. Socio-demographic characteristics have gained a lot of attention as the key profiling variables. Such characteristics have been employed by many scholars more frequently for the bases of segmenting and profiling green consumers. However, most existing studies of green consumers’ socio-demographic were US based. The present article attempts to review the common hypotheses of socio-demographic characteristics in profiling green consumers. The present article reviews five general hypotheses relating to socio-demographics and environmental consciousness of green consumers, namely the gender, age, education level, income, and occupation hypotheses, as well as the theoretical explanation for each hypothesis. Most previous studies tend to have the same conclusion in the gender, age, education level, and  income characteristics. Critics to socio-demographic characteristics and a need to conduct green marketing research in Indonesia was also reviewed.Key words: profiling, socio-demographic, green consumer, hypotheses.

    We present an approach that aims to comprehensively account for scientists’ academic engagement and commercialization activities. While previous research has pointed to the economic and social impact of these activities, it has also been hampered by the difficulties of accurately quantifying them....... Our approach complements university administrative records with data retrieved from external sources and surveys to quantify academic consulting, patenting, and academic entrepreneurship. This allows us to accurately account for ‘independent’ activity, i.e., academic engagement and commercialization...... by not accounting for independent activities. However, with the exception of consulting, we find no significant differences between individuals involved in supported (university-recorded) and independent activity, respectively. Our study contributes to work concerned with developing appropriate and accurate...

    Full Text Available The aim of this paper is to study of the generation accounts for Iranian’s generation. We applied the method of Auerbach, Gokhale and Kotlihoff (1991 on the period 1967-2008 in Iran. Our calculation shows with compare to industrial countries, fiscal burden for Iranian’s population is very chip and that depend on fiscal system in Iran. Except the recent years the rate of tax in Iran has been very low. The generation account for the old people (40 olds is 2117 $ but the future generation (t+1 is 36985 $. The share of male and female, during the years, in this burden is similar. Fiscal burden for Iranian’s generation is low but this population should support other burden that calls inflation. Because when the government do not receive the tax income, a low generation account transfer to price general level.

  1. Do prevailing societal models influence reports of near-death experiences?: a comparison of accounts reported before and after 1975.

    Transcendental near-death experiences show some cross-cultural variation that suggests they may be influenced by societal beliefs. The prevailing Western model of near-death experiences was defined by Moody's description of the phenomenon in 1975. To explore the influence of this cultural model, we compared near-death experience accounts collected before and after 1975. We compared the frequency of 15 phenomenological features Moody defined as characteristic of near-death experiences in 24 accounts collected before 1975 and in 24 more recent accounts matched on relevant demographic and situational variables. Near-death experience accounts collected after 1975 differed from those collected earlier only in increased frequency of tunnel phenomena, which other research has suggested may not be integral to the experience, and not in any of the remaining 14 features defined by Moody as characteristic of near-death experiences. These data challenge the hypothesis that near-death experience accounts are substantially influenced by prevailing cultural models.

  2. Complexity and demographic explanations of cumulative culture.

    Directory of Open Access Journals (Sweden)

    Adrien Querbes

    Full Text Available Formal models have linked prehistoric and historical instances of technological change (e.g., the Upper Paleolithic transition, cultural loss in Holocene Tasmania, scientific progress since the late nineteenth century to demographic change. According to these models, cumulation of technological complexity is inhibited by decreasing--while favoured by increasing--population levels. Here we show that these findings are contingent on how complexity is defined: demography plays a much more limited role in sustaining cumulative culture in case formal models deploy Herbert Simon's definition of complexity rather than the particular definitions of complexity hitherto assumed. Given that currently available empirical evidence doesn't afford discriminating proper from improper definitions of complexity, our robustness analyses put into question the force of recent demographic explanations of particular episodes of cultural change.

    As population scientists have expanded the range of topics they study, increasingly considering the interrelationship between population phenomena and social, economic, and health conditions, they have expanded the kinds of data collected and have brought to bear new data collection techniques and procedures, often borrowed from other fields. These new approaches to demographic data collection are the concern of this essay. We consider three main topics: new developments in sampling procedures; new developments in fieldwork procedures; and new developments in the kind of information collected in demographic and social surveys. We conclude with some comments on data sharing in the social research community and a list of major Chinese surveys publicly available to researchers. Where possible we illustrate our points with Chinese examples. PMID:23844330

    1996-10-01

    A model is developed that enables the authors to estimate the effects of demographic cycles on both earnings and schooling. The model is tested using data from the 1991 Korean Occupational Wage Survey. The results indicate that cohorts following large birth cohorts in the cycle choose relatively less formal schooling compared to pre-peak cohorts, and that post-peak cohorts also have lower incomes. This result concerning South Korea is consistent with findings from previous studies concerning the United States.

    2014-12-01

    Design/methodology/approach- Using a quantitative methodological approach, a survey based on SERVQUAL instrument was applied in order to evaluate local public communication. Data from a sample of 380 citizens within Western Romanian were analyzed. Specific demographic predictors that can influence citizens' satisfaction regarding the quality of communication are analyzed. Findings-By analyzing data it was possible to determine citizen satisfaction and to assess its relationship with different demographic characteristics. The results illustrate that gender does not significantly affect satisfaction, instead age, marital status, residence location (urban versus rural, income, education and occupational status of the respondents significantly affect satisfaction regarding local public communication. In addition, the findings confirm a relationship between the citizens' satisfaction and the age, income, education and occupational status of the respondents. Research limitations/implications- Owing to the budget and time limits, only a one-shot survey was conducted, therefore the comparison between “before” and “after” analysis could not be performed. In addition, further research should investigate the local public communication within national contexts. Practical implications -The adapted SERVQUAL scale may be used by institution managers to objectively assess communication performance and local authority service quality. Originality/value- There continues to be a lack of research regarding the communication process within local public administration and the effect of demographic predictors of communication satisfaction. This paper examines both the perceptions and the expectations of citizens regarding public communication. The results offer insights into residence location, age, income, education and occupational status effects on evaluations of communication satisfaction. Finally, the study contributes to studies of perceived service quality by bearing out

When child mortality falls from lower prevalence, as it did in western Europe, labor productiv...

  15. Development of reprogenetics and its demographic aspects

    Devedžić Mirjana M.

    2004-01-01

    Full Text Available The development of reprogenetics during the last two decades of the XX century has brought a new age of reproduction. The paper surveys different types of reprogenetics in a wider sense, i.e. different assisted reproductive technologies (ART that include manipulation of female reproductive cell out of a woman's womb. Development of reprogenetics is documented by available quantitative indicators of the number and success of ART procedures in developed countries at the beginning of the XXI century. Since 1978, when the first baby was born from in vitro fertilization, the number of children born that way has reached 1% of all children, and in some countries even over 3%. Moreover, existing documentation is incomplete and does not include all forms of assisted reproduction - in reality, the importance of assisted reproduction is even higher and becomes demographically significant. Hence the paper indicates existing and potential effects of the ART development on the demographic development i.e. on specific demographic aspects of this phenomenon. It also points out the effects on the level of fertility, on the changes of direct fertility determinants, and on the levels of mortality and infant mortality, as well as a new understanding of birth control, the possibility of affecting biological structures, and the changes of the fundaments of marriage and family. Development perspectives of reprogenetics are also being raised in the context of bioethical discussions and indicate ethical dilemmas related to assisted reproduction. Solutions to the dilemmas define the scope of applying new reproductive technologies in the future.

  16. Intelligent system to study demographic evolution

    Rodrigues, M. de Fatima; Ramos, Carlos; Henriques, Pedro R.

    1999-02-01

    With three centuries of existence, the study of population's behavior implies the manipulation of large amounts of incomplete and imprecise data with high dimensionality. By virtue of its multidisciplinary character, the work in demography involves at least historicists, statisticians and computer scientists/programmers. Moreover, successful demographic analysis requires qualified experts, who have succeeded in analysing data through many views and relate different sources of information, including their personal knowledge of the epoch or regions under study. In this paper, we present an intelligent system to study demographic evolution (ISSDE). This system has a module based on on-line analytical processing (OLAP), which permits conducting multiple analysis, combining many data dimensions. It has a deductive database system, which allows the execution of elaborated queries through the database. It has another module for date treatment (generalization and/or reduction); and, at last, a data mining module to discover nontrivial relations hidden within data. We discover the data treatment procedure with two phases: data generalization and data reduction. In data generalization, utilizing knowledge about concept hierarchies and relevance of data, aggregation of attribute values is performed. In the data reduction phase, rough set theory is applied to compute the minimal attribute set. We highlight the advantages of combining attribute value generalization with rough set theory, to find a subset of attributes that lets the mining process discover more useful patterns, by providing results from the application of the C5.0 algorithm in a demographic relational database.

    Parabens are broad-spectrum antimicrobial agents used in a range of consumer products, including personal care products, cosmetics, and food. Recently, the widespread use of parabens has raised concerns about the potential health risks associated with their endocrine-disrupting effect. In the present study, 2541 urine samples were collected and analyzed by liquid chromatography-mass spectrometry for the determination of the concentrations of methyl paraben (MeP), ethyl paraben (EtP), propyl paraben (PrP) and butyl paraben (BuP). The detection rate and geometric mean concentrations of parabens in the general population followed the order MeP (97.7%; 116ng/mL)>EtP (97.2%; 24.7ng/mL)>PrP (96.7%; 11.0ng/mL)>BuP (83.5%; 1.13ng/mL). The composition profiles showed that MeP and EtP accounted for >90% of the urinary paraben concentration. We performed statistical analysis in order to evaluate differences between demographic variables and urinary concentrations. Our results showed that adjusted proportional change of MeP, PrP, and BuP in adults were 2.67-6.13 times higher in females than in males. The urinary concentrations of PrP in adults increased significantly with age. The adjusted proportional changes of MeP and PrP in adults were associated with increased body mass index (BMI). The adjusted proportional changes of BuP and PrP in children and adolescents were 1.44 and 1.69 times higher in females than in males. However, there was no clear association between paraben concentrations and demographic variables in the children and adolescents groups. The estimated daily intake (EDIurine) of MeP and EtP in adults were 301μg/kg bw/day, which is lower than the acceptable daily intake (ADI; 10mg/kg bw/day). In summary, our results revealed that the general population in Korea was exposed to parabens during 2009-2010, and most Koreans are exposed to parabens. The urinary levels of parabens varied by age group with demographic factors in the Korean population. The results of
