    This work argues that doubts concerning the reliability of demographic information in Mexico from censuses and other sources should prompt a search for ways of improving existing data rather than developing new data sources and measurement techniques. The example of labor force data is used to illustrate the achievements of past data collection efforts and to suggest a framework for reconciling statistics from diverse sources and exploiting existing sources more fully. From a practical perspective, it would be difficult to identify a nontraditional source of information, statistical procedure, or conceptual framework for collection of labor force and other demographic data that has not been tried somewhere, at some time. Economists and other social scientists who have analyzed the adequacy of existing data sources have pointed to the financial implications of extensive alterations in them and have suggested new questions to be added to censuses and surveys to fill gaps in information. Studies based on census data have been particularly effective in furthering understanding of the supply of labor in Mexico and the factors affecting behavior of the economically active population. Economic surveys have contributed to analysis of employment in the different sectors and the characteristics of workers in different types of establishments and activities. Surveys, both specialized and multipurpose, have also contributed to knowledge of employment and the labor market, especially in urban areas and in aspects related to migration. To classify the different potential sources of labor force data, 2 tables are presented. The 1st lists continuous, periodic, and sporadic sources of data produced in the public, social, and private sectors. The listing of different data sources suggests the rich potential for combining findings from different sources, e.g., correlating deaths occurring in a certain time period to working age adults with information derived from the census to

    Full Text Available Introduction: To evaluate the relationship between various biochemical, nutritional and demographic factors with immune response to hepatitis B vaccine in maintenance hemodialysis (HD patients. Material and Methods: A retro-prospective study was carried out on 68 patients undergoing maintenance hemodialysis .Patients were vaccinated against hepatitis B virus with an intramuscular hepatitis B vaccination schedule, 40 micrograms at 0, 1, and 6 months. We also selected 32 age matched normal healthy persons who had vaccinated against hepatitis B previously to compare the antibody production with HD patients. Results: The value of serum antibody level against hepatitis B surface antigen ( HBs in hemodialisis patients and healthy persons were 35±55(median=5.5 and 135±71 (median=175 mIU/ml respectively. There was a significant deference between mean serum antibody level against HBs antigen of hemodialysis patients and normal subjects (p<0.001, there were not any significant differences of antibody production against HBs antigen between males and females or diabetic and non diabetics. There were no correlation between serum antibody level against HBs-Ag and serum albumin and also with body mass index. There were not significant correlation between anti-HBs antibody level and age, amounts of hemodialysis, duration of dialysis, dialysis adequacy, serum ferritin level and serum lipids. There were not also significant correlation between anti-HBs antibody level and serum parathormone, calcium, phosphorus, serum hemoglobin and hematocrit level. Conclusion: In this study, there was not significant correlation between serum antibody level against hepatitis B surface antigen and various nutritional and demographic factors of patients under regular hemodialysis.

    The purpose of this study is to examine whether evacuee compliance behavior with route assignments from different resolutions of demographic data would impact the evacuation performance. Most existing evacuation strategies assume that travelers will follow evacuation instructions, while in reality a certain percent of evacuees do not comply with prescribed instructions. In this paper, a comparison study of evacuation assignment based on Traffic Analysis Zones (TAZ) and high resolution LandScan USA Population Cells (LPC) were conducted for the detailed road network representing Alexandria, Virginia. A revised platform for evacuation modeling built on high resolution demographic data and activity-based microscopic traffic simulation is proposed. The results indicate that evacuee compliance behavior affects evacuation efficiency with traditional TAZ assignment, but it does not significantly compromise the efficiency with high resolution LPC assignment. The TAZ assignment also underestimates the real travel time during evacuation, especially for high compliance simulations. This suggests that conventional evacuation studies based on TAZ assignment might not be effective at providing efficient guidance to evacuees. From the high resolution data perspective, traveler compliance behavior is an important factor but it does not impact the system performance significantly. The highlight of evacuee compliance behavior analysis should be emphasized on individual evacuee level route/shelter assignments, rather than the whole system performance.

    The rate of organ donation by older potential donors is significantly declining even though recent studies show positive clinical outcomes with organs transplanted from older donors. This study examined the 50+ age demographic to identify the rationale for donation decisions, preferred media methods of donation information delivery, and responsiveness to an age-tailored donation message. Results from 579 surveys, 87% from the 50+ age demographic, found respondents prone to self-select themselves as medically ineligible based on current medication and health status, even though they might be medically suitable donors. Their incentive to pursue additional information on donation is limited except when motivated by personal accounts within their families and communities. In addition, even when computer literate, they continue to favor the printed or spoken word for donation information delivery. The results suggest an opportunity for those working with older adults to develop more personalized, localized donation education programs targeting this age demographic.

    Full Text Available Objective: To determine the levels of Polychlorinated biphenyls (PCBs and Polybrominateddiphenyl ethers (PBDEs as persistent organic pollutants (POPs in serum of primiparous women at the third trimester of pregnancy and identify the main determinants of POPs levels such as socio-demographic, lifestyle, and diet in Tehran.Materials and methods: One- hundred eighty five serum samples from two simultaneous case-control studies were collected from September 2013 until August 2015.Ten most abundant PCB congeners (International Union of Pure and Applied Chemistry (IUPAC congeners 28, 52, 74, 99, 101, 118, 138, 153, 180 and 187 as well as eight PBDE congeners (IUPAC congeners 28, 47, 99, 100, 153, 154, 183 and 209were analyzed by Gas Chromatography Mass Spectrometry (GC/MS. Multiple linear regression analysis was conducted to explain the relationship between total PCBs and total BPDEs and most detected congeners and some determinants, separately.Results: The mean (SD age of the participating women was 27.82 ± 5.24 years. The geometric mean (SD of total PCBs was 2.42 ± 2.26 and total PBDEs was 1.28 ± 1.41 ng/g lipid. Only the PCB 138, PCB 153 and PBDE 153 were detected in 100% of samples. We observed a significant relationship between the time of being indoors and total PBDEs (P = 0.03. Passive smoking was significantly associated with PCB 153 (P = 0.049. The results of the linear regression analysis showed the negative and weak association (P-value < 0.05 between diet (egg and fat and oil consumption and POPs in this population.Conclusion: It seems the most common route of exposure to PBDEs in our population is indoor pollutants. Meanwhile inhalation of smoke from environment is a route of exposure to PCB 153. Further study is needed to evaluate the effects of socio-demographics and especially dietary intake on POPs level.

    Sexual information sources used by young adults can influence their contraceptive knowledge and behaviors, yet little is known about sources most frequently used by young adults, especially by groups with histories of sexual risk involvement. Nationally representative data from 1800 unmarried young adults, aged 18-29 years, were analyzed to (1) examine the sources of contraceptive information most frequently used by young adults and (2) assess variations (if any) in source use based on demographic characteristics and sexual risk history (determined based on past sexual behaviors). "Doctors/nurses" was the most frequently used contraceptive information source reported by young adults. Significant variations existed in source use based on demographic characteristics and sexual risk history. Females were more likely to obtain contraceptive information from health care professionals, whereas males were more likely to report friends, partners, internet and television/radio as their frequently used source. Young adults with a sexual risk history were more likely to rely on doctors/nurses and less likely to report friends and internet as their frequently used source than those without a sexual risk history. Receiving contraceptive information from doctors/nurses was associated with greater accuracy in knowledge about contraceptive use and efficacy as compared to all other sources. Young adults' use of specific contraceptive information sources can vary based on their demographic characteristics and sexual risk involvement. Future research should identify better strategies to connect young adults, especially young males, with sexual risk histories to more reliable sources of information. Copyright © 2015 Elsevier Inc.

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

    Aflatoxins are one of the major risk factors in the multi-factorial etiology of human hepatocellular carcinoma. Therefore, the information on aflatoxins exposure is very important in the intervention planning in order to reduce the dietary intake of aflatoxins, especially among the children. This study investigated the relationship between aflatoxin B(1) (AFB(1)) lysine adduct levers in serum and socio-demographic factors and dietary intake of aflatoxins from nuts and nut products in Penang, Malaysia. A cross-sectional field study was conducted in five districts of Penang. A survey on socio-demographic characteristics was administered to 364 healthy adults from the three main ethnic groups (Malay, Chinese and Indian). A total of 170 blood samples were successfully collected and tested for the level of AFB(1)-lysine adduct. 97% of the samples contained AFB(1)-lysine adduct above the detection limit of 0.4 pg/mg albumin and ranged from 0.20 to 23.16 pg/mg albumin (mean±standard deviation=7.67±4.54 pg/mg albumin; median=7.12 pg/mg albumin). There was no significant association between AFB(1)-lysine adduct levels with gender, district, education level, household number and occupation when these socio-demographic characteristics were examined according to high or low levels of AFB(1)-lysine. However, participants in the age group of 31-50 years were 3.08 times more likely to have high AFB(1) levels compared to those aged between 18 and 30 years (P=0.026). Significant difference (P=0.000) was found among different ethnic groups. Chinese and Indian participants were 3.05 and 2.35 times more likely to have high AFB(1) levels than Malay. The result of AFB(1)-lysine adduct suggested that Penang adult population is likely to be exposed to AFB(1) but at a level of less than that needed to cause direct acute illness or death.

    Computerised identity management is in general encountered as a low-level mechanism that enables users in a particular system or region to securely access resources. In the Electronic Health Record (EHR), the identifying information of both the healthcare professionals who access the EHR and the patients whose EHR is accessed, are subject to change. Demographics services have been developed to manage federated patient and healthcare professional identities and to support challenging healthcare-specific use cases in the presence of diverse and sometimes conflicting demographic identities. Demographics services are not the only use for identities in healthcare. Nevertheless, contemporary EHR specifications limit the types of entities that can be the actor or subject of a record to health professionals and patients, thus limiting the use of two level models in other healthcare information systems. Demographics are ubiquitous in healthcare, so for a general identity model to be usable, it should be capable of managing demographic information. In this paper, we introduce a generalised identity reference model (GIRM) based on key characteristics of five surveyed demographic models. We evaluate the GIRM by using it to express the EN13606 demographics model in an extensible way at the metadata level and show how two-level modelling can support the exchange of instances of demographic identities. This use of the GIRM to express demographics information shows its application for standards-compliant two-level modelling alongside heterogeneous demographics models. We advocate this approach to facilitate the interoperability of identities between two-level model-based EHR systems and show the validity and the extensibility of using GIRM for the expression of other health-related identities.

    The Chart Graphic Analysis and Display System was developed as part of Lawrence Berkeley Laboratory's Socio-Economic-Environmental-Demographic Information System (SEEDIS) to provide a tool with which users could draw graphs, print tables of numbers, do analysis, and perform basic statistical operations on the same set of data from a terminal in their own office. The Chart system's operation is completely independent of the type of data being entered and has been used for applications ranging from employment to energy data. Users frequently save the data they put into Chart and add to it on a regular basis, and thereby create personal databases which can be blended with information from the formal databases maintained at LBL. Using any computer system requires that the user learn a set of instructions, which at the onset often seems overwhelming. It is the purpose of this workbook to make this initial learning process less traumatic. The typical use of Chart is to enter a set of numbers, and then tell Chart what should be done with them. Chart commands take the form of gruff pidgin English. There are approximately 50 commands available. This workbook illustrates the basic commands. (RWR)

    Non-steroidal anti-inflammatory drugs (NSAIDs) are frequently prescribed for musculoskeletal pain and inflammatory conditions. A better understanding of patient information seeking behavior can help bridge the gap between patient knowledge and health care resources. This study examines the primary sources of NSAID risk information and the associations with patient socio-demographic factors. A cross-sectional survey analysis of patients on prescription NSAIDs (n=220) seen by primary care physicians in Alabama. Bivariate and multivariable, multinomial logistic regression analyses were conducted to evaluate the associations among primary NSAID risk information sources used with patient socio-demographic factors. The primary patient source of information on NSAID risks was physician (57.3%), followed by internet (16.8%), pharmacist (16.4%), and other sources, such as nurses and family/friends (9.6%). Compared to people who use the internet as a primary source of NSAID risk information, patients who were Black/African-American (p=0.002) and 65 years of age or older (p=0.009) were more likely to use a physician. Older patients were also more likely to use a pharmacist (p=0.008) than the internet. In contrast, females (p=0.032) were less likely to use the pharmacist compared to the internet (p=0.032). Patients obtain information from a variety of sources, but primarily from health care providers. While the internet is a fast growing source of health information, socio-demographic disparities in internet use for seeking information exist. Health care providers should be aware of their patient preferences for information sources on medication risks to meet the age, race, and gender need differences of all patients.

    Beta thalassemia is the most frequent genetic disorder of haemoglobin synthesis in Pakistan. Recurrent transfusions lead to iron-overload manifested by increased serum Ferritin levels, for which chelation therapy is required. The study was conducted in the Pediatric Emergency unit of Civil Hospital Karachi after ethical approval by the Institutional Review Board of Dow University of Health Sciences. Seventy nine cases of beta thalassemia major were included after a written consent. The care takers were interviewed for the socio-demographic variables and the use of Desferrioxamine therapy, after which a blood sample was drawn to assess the serum Ferritin level. SPSS 15.0 was employed for data entry and analysis.Of the seventy-nine patients included in the study, 46 (58.2%) were males while 33 (41.8%) were females. The mean age was 10.8 (± 4.5) years with the dominant age group (46.2%) being 10 to 14 years. In 62 (78.8%) cases, the care taker education was below the tenth grade. The mean serum Ferritin level in our study were 4236.5 ng/ml and showed a directly proportional relationship with age. Desferrioxamine was used by patients in 46 (58.2%) cases with monthly house hold income significant factor to the use of therapy. The mean serum Ferritin levels are approximately ten times higher than the normal recommended levels for normal individuals, with two-fifths of the patients not receiving iron chelation therapy at all. Use of iron chelation therapy and titrating the dose according to the need can significantly lower the iron load reducing the risk of iron-overload related complications leading to a better quality of life and improving survival in Pakistani beta thalassemia major patients.Conflicts of Interest: None.

    To identify different segments of U.S. consumers based on food choices, exercise patterns, and desire for restaurant calorie labeling. Using a stratified (by region) random sample of the U.S. population, trained interviewers collected data for this cross-sectional study through telephone surveys. Center for Rural Studies U.S. national health survey. The final sample included 580 responses (22% response rate); data were weighted to be representative of age and gender characteristics of the U.S. population. Self-reported behaviors related to food choices, exercise patterns, desire for calorie information in restaurants, and sample demographics. Clusters were identified using Schwartz Bayesian criteria. Impacts of demographic characteristics on cluster membership were analyzed using bivariate tests of association and multinomial logit regression. Cluster analysis revealed three clusters based on respondents' food choices, activity levels, and desire for restaurant labeling. Two clusters, comprising three quarters of the sample, desired calorie labeling in restaurants. The remaining cluster opposed restaurant labeling. Demographic variables significantly predicting cluster membership included region of residence (p restaurant calorie labeling. Specific demographic clusters could be targeted through labeling initiatives.

    Range expansion and contraction has occurred in the history of most species and can seriously impact patterns of genetic diversity. Historical data about range change are rare and generally appropriate for studies at large scales, whereas the individual pollen and seed dispersal events that form the basis of geneflow and colonization generally occur at a local scale. In this study, we investigated range change in Fagus sylvatica on Mont Ventoux, France, using historical data from 1838 to the present and approximate Bayesian computation (ABC) analyses of genetic data. From the historical data, we identified a population minimum in 1845 and located remnant populations at least 200 years old. The ABC analysis selected a demographic scenario with three populations, corresponding to two remnant populations and one area of recent expansion. It also identified expansion from a smaller ancestral population but did not find that this expansion followed a population bottleneck, as suggested by the historical data. Despite a strong support to the selected scenario for our data set, the ABC approach showed a low power to discriminate among scenarios on average and a low ability to accurately estimate effective population sizes and divergence dates, probably due to the temporal scale of the study. This study provides an unusual opportunity to test ABC analysis in a system with a well-documented demographic history and identify discrepancies between the results of historical, classical population genetic and ABC analyses. The results also provide valuable insights into genetic processes at work at a fine spatial and temporal scale in range change and colonization.

  19. Demographic and health surveillance of mobile pastoralists in Chad: integration of biometric fingerprint identification into a geographical information system

    2008-11-01

    Full Text Available There is a pressing need for baseline demographic and health-related data to plan, implement and evaluate health interventions in developing countries, and to monitor progress towards international development goals. However, mobile pastoralists, i.e. people who depend on a livestock production system and follow their herds as they move, remain marginalized from rural development plans and interventions. The fact that mobile people are hard to reach and stay in contact with is a plausible reason why they are underrepresented in national censuses and/or alternative sequential sample survey systems. We present a proof-of-concept of monitoring highly mobile, pastoral people by recording demographic and health-related data from 933 women and 2020 children and establishing a biometric identification system (BIS based on the registration and identification of digital fingerprints. Although only 22 women, representing 2.4% of the total registered women, were encountered twice in the four survey rounds, the approach implemented is shown to be feasible. The BIS described here is linked to a geographical information system to facilitate the creation of the first health and demographic surveillance system in a mobile, pastoralist setting. Our ultimate goal is to implement and monitor interventions with the “one health” concept, thus integrating and improving human, animal and ecosystem health.

    The growing diversity of the online health information community is increasingly cited as a limiting factor related to the potential of the Internet as an effective health communication channel and information resource. Public-access Internet portals and decreasing costs of personal computers have created a consensus that unequal access to information, or a "Digital Divide," presents a like problem specific to health care consumers. Access to information, however, is an essential part of the consumer-centric framework outlined in the recently proposed U.S. National Health Information Infrastructure (NHII) and Health Architecture initiatives. To date little research has been done to differentiate the types of health information sought on the Web by different subgroups, linking user characteristics and health-seeking behaviors. Data from a study of consumer Web search activity in a post-intervention era serves as a natural experiment, and can identify whether a "digitally underserved group" persists in the United States. Such an environment would serve to exclude traditionally underserved groups from the benefits of the planned national heath information infrastructure. This exploratory technology assessment study seeks to differentiate and delineate specific behaviors, or lack of desired behaviors, across targeted health care subgroups. Doing so allows the design of more effective strategies to promote the use of the Web as a health education and health promotion tool, under the envisioned shared decision-making, consumer-centric health information model.

    The prevalence of HIV&AIDS is embedded in social and economic inequity and the relationship between social determinants and HIV incidence is well established. The aim of this study was to determine which socio-economic and demographic factors are related to HIV status in the age group 18 to 49 years in informal settlements in the Eastern Cape, South Africa. This cross-sectional study was conducted in 3 informal settlements (n = 752) during March 2013 within the Nelson Mandela Bay and Buffalo City districts. A proportional cluster sample was selected and stratified by area and formal plot/squatter households in open areas. Respondents who volunteered to participate had to provide informed written consent before trained, bilingual peer educators interviewed them and completed the structured questionnaire. HIV status was determined and information on demographic and socio-economic variables was included in the bivariate analysis. The prevalence of HIV was higher, at 17.3%, than the 2011 estimated national prevalence among the general population in South Africa. The level of education (χ(2) = 5.50, df = 1, p food insecurity (χ(2) = 4.77, df = 1, p < 0.05), cooking with cast iron pots (χ(2) = 15.0, df = 3, p < 0.05) and availability of perceived 'wealth' indicators like mobile telephones and refrigerators (χ(2) = 9.67, df = 2, p < 0.05) were significantly associated with HIV-status. No significant associations could be demonstrated between household income, the number of people living in the household and the availability of electricity/water and HIV status. As the observed levels of HIV prevalence underlined gender bias and failure to graduate from high school, future interventions should focus on HIV prevention in female schoolchildren. However, HIV infection is also prevalent among wealthier individuals in informal settlements, which indicates that renewed efforts should be made to improve sexual risk behaviour within this group.

    Climate change is having widespread ecological effects, including loss of Arctic sea ice. This has led to listing of the polar bear (Ursus maritimus) and other ice-dependent marine mammals under the U.S. Endangered Species Act (ESA). Methods are needed to evaluate the effects of climate change on population persistence to inform recovery planning for listed species. For polar bears, this includes understanding interactions between climate and secondary factors, such as subsistence harvest, which provide economic, nutritional, or cultural value to humans.

    As with other sexual offenders, sexual homicide perpetrators can be reluctant to talk about their criminal behavior. Therefore, in homicide cases, forensic practitioners frequently rely on crime scene information to identify any sexual behavior associated with the offense. This study aims to identify objective and readily available crime scene information, alongside information about victims and perpetrators, based on 65 cases from England and Wales in the United Kingdom of men convicted of homicide who had committed a non-serial sexual homicide and 64 cases of men convicted of homicide where the available evidence indicated that it was a non-serial non-sexual homicide. Chi-square tests and logistic regression were used to analyze the data. There were few differences in terms of demographic information and criminal histories between the two perpetrator groups. There were crime scene indicators supporting the use of Ressler et al.'s definition of sexual homicide. The victims of sexual homicide were generally found in their home with the lower half of the body exposed and with evidence of vaginal sex. Furthermore, extreme injuries and strangulation were more frequent in sexual homicides. Use of weapon was associated with a non-sexual homicide. Victims of sexual homicide were as likely to know the perpetrator as not. Potential benefits of the characteristics reported to investigators and forensic practitioners tasked with identifying sexual homicides are discussed and areas for further research suggested.

    2017-02-01

    This article aims to examine the socio-demographic characteristics associated with access and use of Internet for health-related purposes and its relationship with health literacy. Data were drawn from a health literacy survey ( N = 1046) and analysed using logistic regression. Results show a strong association between health literacy, internet access and use. Socio-demographic characteristics particularly age, education, income, perceived health and social isolation also predict internet access. Thus, in addition to widening access, the movement towards digitisation of health information and services should also consider digital skills development to enable people to utilise digital technology more effectively, especially among traditionally hard-to-reach communities.

    Death Certificate Only (DCO) cancer cases are commonly excluded from survival analyses due to unknown survival time. This study examines whether socio-demographic factors are associated with DCO diagnosis, and the potential effects of excluding DCO cases on socio-demographic cancer survival disparities in NSW, Australia. NSW Cancer Registry data for cases diagnosed in 2000-2008 were used in this study. Logistic regression was used to estimate the odds of DCO registration by socio-demographic sub-group (socio-economic disadvantage, residential remoteness, country of birth, age at diagnosis). Cox proportional hazard regression was used to estimate the probability of death from cancer by socio-demographic subgroup when DCO cases were included and excluded from analyses. DCO cases consisted of 1.5% (n=4336) of all cases (n=299,651). DCO diagnosis was associated with living in socio-economically disadvantaged areas (most disadvantaged compared with least disadvantaged quintile: odds ratio OR 1.25, 95%CI 1.12-1.40), living in inner regional (OR 1.16, 95%CI 1.08-1.25) or remote areas (OR 1.48, 95%CI 1.01-2.19), having an unknown country of birth (OR 1.63, 95%CI 1.47-1.81) and older age. Including or excluding DCO cases had no significant impact on hazard ratios for cancer death by socio-economic disadvantage quintile or remoteness category, and only a minor impact on hazard ratios by age. Socio-demographic factors were associated with DCO diagnosis in NSW. However, socio-demographic cancer survival disparities remained unchanged or varied only slightly irrespective of including/excluding DCO cases. Further research could examine the upper limits of DCO proportions that significantly alter estimated cancer survival differentials if DCOs are excluded. Crown Copyright © 2017.

  9. Information about the US racial demographic shift triggers concerns about anti-White discrimination among the prospective White “minority”

    2017-01-01

    The United States is undergoing a demographic shift in which White Americans are predicted to comprise less than 50% of the US population by mid-century. The present research examines how exposure to information about this racial shift affects perceptions of the extent to which different racial groups face discrimination. In four experiments, making the growing national racial diversity salient led White Americans to predict that Whites will face increasing discrimination in the future, compared with control information. Conversely, regardless of experimental condition, Whites estimated that discrimination against various racial minority groups will decline. Explorations of several psychological mechanisms potentially underlying the effect of the racial shift information on perceived anti-White discrimination suggested a mediating role of concerns about American culture fundamentally changing. Taken together, these findings suggest that reports about the changing national demographics enhance concerns among Whites that they will be the victims of racial discrimination in the future.

    Independent inventors are important but little-researched members of the US technical community. The survey reported on here is the first in modern times to attempt to provide a profile of the US independent inventor that goes beyond a single geographical or organizational locale. The report that follows provides an overview of the demographics, practices and concerns of the modern US inventor as represented by the members of leading US inventor organizations. It is by no means comprehensive but seeks to be indicative of the issues raised in the survey each which will be dealt with more comprehensively in future publications.

    Changing climatic, demographic, and land use conditions are projected to alter the provisioning of ecosystem services in estuarine, coastal, and nearshore marine ecosystems, necessitating mitigation and adaptation policies and management. The current paradigm of research efforts occurring in parallel to, rather than in collaboration with, decision makers will be insufficient for the rapid responses required to adapt to and mitigate for projected changing conditions. Here, we suggest a different paradigm: one where research begins by engaging decision makers in the identification of priority data needs (biophysical, economic, and social). This paper uses synthesized interview data to provide insight into the varied demands for scientific research as described by decision makers working on coastal issues in Oregon, USA. The findings highlight the need to recognize (1) the differing framing of ecosystem services by decision makers versus scientists; and (2) the differing data priorities relevant to inland versus coastal decision makers. The findings further serve to highlight the need for decision makers, scientists, and funders to engage in increased communication. This research is an important first step in advancing efforts toward evidence-based decision making in Oregon and provides a template for further research across the US.

The research presented in this article is intended to help address this information gap, by investigating influences on adult environmental literacy using data from a Minnesota environmental literacy survey. The article presents the research findings regarding the influence of demographicfactors and of non-formal and informal learning on environmental behavior, one of the key dimensions of environmental literacy. Results from this study indicated that environmental behavior prediction was most improved by adding non-formal and informal learningparticipation. These results suggest that non-formal and informal learning options should be looked at more carefully for predictive possibilities.

    Full Text Available The purpose of this paper is to investigate the relationship between the usage and perceived credibility of several sources of information domestic travelers take into consideration when gathering information on potential accommodation providers, on one hand, and, respectively, travelers’ demographic characteristics, on the other hand. After analyzing data from an online questionnaire based study conducted among a sample of 346 young Romanian Facebook users (between 19 and 35 years old, the results showed that, considering types of information sources usually taken into consideration, personal sources and Facebook are more frequently found among travelers with a lower income, travel agencies are more frequently mentioned as usual sources of information among older travelers and among those with a higher level of education, while women are more inclined than men to use leaflets and booklets as sources of information on accommodation providers. Moreover, the research showed that the higher the income, the higher the level of perceived credibility of online portals is. Also, travel agencies and personal sources are more frequently mentioned among the most credible sources by women, than by men, while men are slightly more confident than women in online banners and blogs. The findings can be very useful and relevant from a practical perspective, especially for communication and promotion purposes in the hospitality industry.

    Hydrocortisone therapy is based on a dosing regimen derived from estimates of cortisol secretion, but little is known of how the dose should be distributed throughout the 24 h. We have used deconvolution analysis of 24-h serum cortisol profiles to determine 24-h cortisol secretion and distribution to inform hydrocortisone dosing schedules in young children and older adults. Twenty four hour serum cortisol profiles from 80 adults (41 men, aged 60-74 years) and 29 children (24 boys, aged 5-9 years) were subject to deconvolution analysis using an 80-min half-life to ascertain total cortisol secretion and distribution throughout the 24-h period. Mean daily cortisol secretion was similar between adults (6.3 mg/m(2) body surface area/day, range 5.1-9.3) and children (8.0 mg/m(2) body surface area/day, range 5.3-12.0). Peak serum cortisol concentration was higher in children compared with adults, whereas nadir serum cortisol concentrations were similar. Timing of the peak serum cortisol concentration was similar (07.05-07.25), whereas that of the nadir concentration occurred later in adults (midnight) compared with children (22.48) (P = 0.003). Children had the highest percentage of cortisol secretion between 06.00 and 12.00 (38.4%), whereas in adults this took place between midnight and 06.00 (45.2%). These observations suggest that the daily hydrocortisone replacement dose should be equivalent on average to 6.3 mg/m(2) body surface area/day in adults and 8.0 mg/m(2) body surface area/day in children. Differences in distribution of the total daily dose between older adults and young children need to be taken into account when using a three or four times per day dosing regimen. © 2012 Blackwell Publishing Ltd.

  17. Metabolomic Screening of Tumor Tissue and Serum in Glioma Patients Reveals Diagnostic and Prognostic Information

    Full Text Available Glioma grading and classification, today based on histological features, is not always easy to interpret and diagnosis partly relies on the personal experience of the neuropathologists. The most important feature of the classification is the aimed correlation between tumor grade and prognosis. However, in the clinical reality, large variations exist in the survival of patients concerning both glioblastomas and low-grade gliomas. Thus, there is a need for biomarkers for a more reliable classification of glioma tumors as well as for prognosis. We analyzed relative metabolite concentrations in serum samples from 96 fasting glioma patients and 81 corresponding tumor samples with different diagnosis (glioblastoma, oligodendroglioma and grade (World Health Organization (WHO grade II, III and IV using gas chromatography-time of flight mass spectrometry (GC-TOFMS. The acquired data was analyzed and evaluated by pattern recognition based on chemometric bioinformatics tools. We detected feature patterns in the metabolomics data in both tumor and serum that distinguished glioblastomas from oligodendrogliomas (ptumor = 2.46 × 10−8, pserum = 1.3 × 10−5 and oligodendroglioma grade II from oligodendroglioma grade III (ptumor = 0.01, pserum = 0.0008. Interestingly, we also found patterns in both tumor and serum with individual metabolite features that were both elevated and decreased in patients that lived long after being diagnosed with glioblastoma compared to those who died shortly after diagnosis (ptumor = 0.006, pserum = 0.004; AUROCCtumor = 0.846 (0.647–1.000, AUROCCserum = 0.958 (0.870–1.000. Metabolic patterns could also distinguish long and short survival in patients diagnosed with oligodendroglioma (ptumor = 0.01, pserum = 0.001; AUROCCtumor = 1 (1.000–1.000, AUROCCserum = 1 (1.000–1.000. In summary, we found different metabolic feature patterns in tumor tissue and serum for glioma diagnosis, grade and survival, which indicates that

    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.

  3. Why would serum phosphorus correlate with cardiovascular risk, and how is the clinician supposed to use this information?

    Science.gov (United States)

    Lederer, Eleanor

    2017-01-01

    Numerous recent studies have demonstrated an association between serum phosphorus and cardiovascular risk, even in individuals with normal kidney function and with serum phosphorus levels considered within the acceptable range. Whether serum phosphorus serves as a biomarker, as a causative agent, or both remains unclear. Additionally, the impact of other important considerations, such as the time of day when the phosphorus is measured, the diet of the individual, and the age of the individual, on interpretation of this association has not been determined. Currently, serum phosphorus cannot be used systematically as an independent cardiovascular risk factor but may be an important adjunctive factor in analyzing cardiovascular risk. More importantly, understanding the basis for the association between serum phosphorus and cardiovascular risk will likely yield new insights into fundamental mechanisms of cardiovascular disease.

    Chalmers Mulwa

    2017-01-01

    Full Text Available Why do many smallholder farmers fail to adopt what appear to be relatively simple agronomic or management practices which can help them cope with climate-induced stressors? Using household and plot level data collected in 2011, we implement a multivariate probit model to assess the determinants of farmer adaptation behavior to climatic risks and the relative contribution of information, credit and education on the probability of adopting specific practices in response to adverse changes in weather patterns. We find that plot characteristics, credit constraints and availability of climate-related information explain the adoption of several of these practices. In relative terms, we also find that even when financial limitations are binding, making climate-related information available can still motivate farmers to adapt. Policy implications are that the deepening of extension access with information on the appropriate adaptation strategies is crucial to help farmers make adaptation choices. The need to foster credit markets for easy accessibility and affordability by farmers or otherwise strengthening access to assets is also important.

  9. 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

    Iringa region of Tanzania has had great success reaching targets for voluntary medical male circumcision (VMMC). Looking to sustain high coverage of male circumcision, the government introduced a pilot project to offer early infant male circumcision (EIMC) in Iringa in 2013. From April 2013 to December 2014, a total of 2,084 male infants were circumcised in 8 health facilities in the region, representing 16.4% of all male infants born in those facilities. Most circumcisions took place 7 days or more after birth. The procedure proved safe, with only 3 mild and 3 moderate adverse events (0.4% overall adverse event rate). Overall, 93% of infants were brought back for a second-day visit and 71% for a seventh-day visit. These percentages varied significantly by urban and rural residence (97.4% urban versus 84.6% rural for day 2 visit; 82.2% urban versus 49.9% rural for day 7 visit). Mothers were more likely than fathers to have received information about EIMC. However, fathers tended to be key decision makers regarding circumcision of their sons. This suggests the importance of addressing fathers with behavioral change communication about EIMC. Successes in scaling up VMMC services in Iringa did not translate into immediate acceptability of EIMC. EIMC programs will require targeted investments in demand creation to expand and thrive in traditionally non-circumcising settings such as Iringa.

  12. 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.

    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.

    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

    2013-01-01

    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

  12. Novel Approaches to Visualization and Data Mining Reveals Diagnostic Information in the Low Amplitude Region of Serum Mass Spectra from Ovarian Cancer Patients

    Directory of Open Access Journals (Sweden)

    Donald J. Johann

    2004-01-01

    Full Text Available The ability to identify patterns of diagnostic signatures in proteomic data generated by high throughput mass spectrometry (MS based serum analysis has recently generated much excitement and interest from the scientific community. These data sets can be very large, with high-resolution MS instrumentation producing 1–2 million data points per sample. Approaches to analyze mass spectral data using unsupervised and supervised data mining operations would greatly benefit from tools that effectively allow for data reduction without losing important diagnostic information. In the past, investigators have proposed approaches where data reduction is performed by a priori “peak picking” and alignment/warping/smoothing components using rule-based signal-to-noise measurements. Unfortunately, while this type of system has been employed for gene microarray analysis, it is unclear whether it will be effective in the analysis of mass spectral data, which unlike microarray data, is comprised of continuous measurement operations. Moreover, it is unclear where true signal begins and noise ends. Therefore, we have developed an approach to MS data analysis using new types of data visualization and mining operations in which data reduction is accomplished by culling via the intensity of the peaks themselves instead of by location. Applying this new analysis method on a large study set of high resolution mass spectra from healthy and ovarian cancer patients, shows that all of the diagnostic information is contained within the very lowest amplitude regions of the mass spectra. This region can then be selected and studied to identify the exact location and amplitude of the diagnostic biomarkers.

  13. Demographic Estimation from Face Images: Human vs. Machine Performance.

    2015-06-01

    Demographic estimation entails automatic estimation of age, gender and race of a person from his face image, which has many potential applications ranging from forensics to social media. Automatic demographic estimation, particularly age estimation, remains a challenging problem because persons belonging to the same demographic group can be vastly different in their facial appearances due to intrinsic and extrinsic factors. In this paper, we present a generic framework for automatic demographic (age, gender and race) estimation. Given a face image, we first extract demographic informative features via a boosting algorithm, and then employ a hierarchical approach consisting of between-group classification, and within-group regression. Quality assessment is also developed to identify low-quality face images that are difficult to obtain reliable demographic estimates. Experimental results on a diverse set of face image databases, FG-NET (1K images), FERET (3K images), MORPH II (75K images), PCSO (100K images), and a subset of LFW (4K images), show that the proposed approach has superior performance compared to the state of the art. Finally, we use crowdsourcing to study the human perception ability of estimating demographics from face images. A side-by-side comparison of the demographic estimates from crowdsourced data and the proposed algorithm provides a number of insights into this challenging problem.

  15. Intelligent system to study demographic evolution

    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.

  19. Democratic constraints on demographic policy.

    Science.gov (United States)

    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

    High-sensitivity C-reactive protein (hs-CRP) has been developed and used as a marker to predict coronary vascular diseases in metabolic syndrome (MS). We investigated whether serum hs-CRP concentration was associated with nonalcoholic fatty liver disease (NAFLD) based on the Akaike Information Criterion (AIC) scoring system, using patients from the human dry dock program. From 2004 to 2005, 1254 subjects visited our human dry dock annual checkup program. We excluded from this study individuals with markers of viral hepatitis and those whose alcohol consumption was more than 20 g/week. Finally, 230 subjects (93 men and 137 women) were investigated. Serum hs-CRP concentrations were measured using a highly sensitive latex agglutination assay system. The AIC scoring system with the CATDAP-20 program was introduced to evaluate the parameters that are present frequently in NAFLD. NAFLD was diagnosed by ultrasound sonography in 35.4% of the men and 18.9% of the women. High serum hs-CRP concentrations were observed in women with NAFLD (normal: NAFLD = 0.45:1.47 mg/l, P < 0.05). Body mass index (BMI), waist circumference, and body weight had the three lowest AIC score (P = 4.5e(-19) to 2.6e(-16)). hs-CRP was the third lowest variable among the serum markers associated with NAFLD (P = 2.3e(-6)) In addition, the hs-CRP concentration was correlated strongly with triglyceride values in females with NAFLD and with fasting blood glucose, HbA1c, and waist/hip ratio in males with NAFLD (P < 0.05). The serum hs-CRP concentration was a strong predictor for NAFLD with a low AIC score and correlated with serum markers that indicated lipid and glucose metabolism.

  1. The Serum CA-125 Concentration Data Assists in Evaluating CT Imaging Information When Used to Differentiate Borderline Ovarian Tumor from Malignant Epithelial Ovarian Tumors

    2011-08-15

    We wanted to evaluate the diagnostic value of serum CA-125 concentration, when used in combination with the preoperative contrast-enhanced CT results, to differentiate borderline ovarian tumors (BOTs) from stage I malignant epithelial ovarian tumors (MEOTs). Ninety-eight masses (46 BOTs and 52 stage I MEOTs) from 87 consecutive patients (49 with BOTs and 38 with stage I MEOTs) who had undergone preoperative contrast-enhanced computed tomography (CT) and surgical staging were evaluated retrospectively and independently by two radiologists. The preoperative serum CA-125 concentration was measured in all patients. The utility of analyzing serum CA-125 concentration in combination with the CT results was evaluated by receiver operating characteristic (ROC) curve analysis. An irregular tumor surface and lymphadenopathy were predictive of a MEOT. ROC analysis showed that the combination of CT data and the serum CA-125 level resulted in a higher diagnostic performance than did using the CT alone for differentiating BOTs from MEOTs. The areas under the curves (AUCs) without and with the use of the serum CA-125 level data were 0.67 (95% confidence interval [CI]: 0.57-0.77) and 0.78 (95% CI: 0.68-0.85), respectively, for reader 1 (p = 0.029) and 0.71 (95% CI: 0.61-0.80) and 0.81 (95% CI: 0.72-0.89), respectively, for reader 2 (p = 0.009). The serum CA-125 concentration is of additional diagnostic value when used in conjunction with the CT imaging results for differentiating BOTs from MEOTs.

  3. Chronological objects in demographic research

    Frans J. Willekens

    2013-03-01

    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.

    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

    Full Text Available The dominance of Jamaican sprinters in international meets remains largely unexplained. Proposed explanations include demographics and favorable physiological characteristics. The aim of this study was to analyze the demographic characteristics of world class Jamaican sprinters. Questionnaires administered to 120 members of the Jamaican national team and 125 controls elicited information on place of birth, language, ethnicity, and distance and method of travel to school. Athletes were divided into three groups based on athletic disciplines: sprint (s: 100–400 m; n=80, jump and throw (j/t: jump and throw; n=25 and, middle distance (md: 800–3000 m; n=15. Frequency differences between groups were assessed using chi-square tests. Regional or county distribution of sprint differed from that of middle distance (P<0.001 but not from that of jump and throw athletes (P=0.24 and that of controls (P=0.59. Sprint athletes predominately originated from the Surrey county (s = 46%, j/t = 37%, md = 17, C = 53%, whilst middle distance athletes exhibited excess from the Middlesex county (md = 60%. The language distribution of all groups showed uniformity with a predominance of English. A higher proportion of middle distance and jump and throw athletes walked to school (md = 80%, j/t = 52%, s = 10%, and C = 12% and travelled greater distances to school. In conclusion, Jamaica’s success in sprinting may be related to environmental and social factors.

    2016-09-01

    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.

  12. Demographic Ageing on Croatian Islands

    2013-08-01

    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.

    Emerging evidence indicates that maternal oxidative stress during pregnancy could impair fetal growth and that antioxidant vitamins (e.g. vitamins A, E and C) have a significant role in maintaining physiological processes of pregnancy and growth. To determine the concentrations of vitamins A, E, and C in pair-matched maternal and cord serum samples of neonate, and thus to investigate the relationship between maternal serum levels of these vitamins at delivery and birth outcomes. A total of 143 mother-neonate pairs were recruited into the cross-sectional descriptive study. Demographic information was investigated by questionnaire. After delivery, both cord and maternal blood were collected for quantification of serum levels of vitamins A, E and C by HPLC. Maternal serum levels of vitamins A and E were significantly higher than those in cord serum. In contrast, vitamin C level in cord serum was significantly higher than that in maternal serum. Further, we found that maternal vitamin A status was significantly correlated to both birth weight (r=0.19, p=0.0419) and birth height (r=0.21, p=0.0311), and these were manifested by these findings: (i) per 250.2 g reduction in birth weight concomitant with 1 micromol/L increase in maternal serum vitamin A level (pvitamin A level of neonate to mother concomitant with 0.8 cm increase in birth height (p=0.049; 95% CI: 0.004-1.639). Maternal vitamin A, but not vitamins E and C, during pregnancy had a significant effect on birth outcomes. Further studies are necessary to investigate the role of these antioxidant vitamins in fetal growth at various gestation stages.

  14. Can the Serum Level of Myostatin be Considered as an Informative Factor for Cachexia Prevention in Patients with Medullary Thyroid Cancer?

    2016-01-01

    Thyroid cancer, the most common endocrine neoplasia, consists of four main types of carcinomas: papillary, follicular, and anaplastic, all with thyroid follicular origin, and medullary thyroid cancer (MTC) related to para-follicular cells. Cronic diseases such as diverse cancers may be associated with cachexia, especially at advanced stage. Cancer-induced cachexia is associated with diminished quality of life, functional performance, reduced response to antitumor therapy, and increased morbidity and mortality. Myostatin (Mst) is one of the outstanding molecules in the skeletal muscle loss process in cancer and it may be released by both skeletal muscle and cachexia-inducing tumors. Recently changes in serum levels of Mst have been identified as an important factor of cancer-induced cachexia. The goal of this study was to assessserum Mst levels in MTC patients. In this descriptive and case-control study, 90 participants were selected, comprising 45 MTC patients (20 males, 29±13.9 years, 25 females, 29±14.5 years) and 45 control individuals (25 males, 23.1±11.6 years, 20 females, 31.5±14.4 years). Serum Mst was determined using an ELISA kit and body mass index (BMI) was calculated by weight and height measurements. The Kolmogorov Simonov test showed a normal distribution for log transformed Mst serum levels in both case and control groups. Geometric means were 5.9 and 8.2 ng/ml respectively, and a significant difference was found according to the independent t-test results (Pcachexia in MTC patients, especially in females.

  15. Composite likelihood estimation of demographic parameters

    2009-11-01

    Full Text Available Abstract Background Most existing likelihood-based methods for fitting historical demographic models to DNA sequence polymorphism data to do not scale feasibly up to the level of whole-genome data sets. Computational economies can be achieved by incorporating two forms of pseudo-likelihood: composite and approximate likelihood methods. Composite likelihood enables scaling up to large data sets because it takes the product of marginal likelihoods as an estimator of the likelihood of the complete data set. This approach is especially useful when a large number of genomic regions constitutes the data set. Additionally, approximate likelihood methods can reduce the dimensionality of the data by summarizing the information in the original data by either a sufficient statistic, or a set of statistics. Both composite and approximate likelihood methods hold promise for analyzing large data sets or for use in situations where the underlying demographic model is complex and has many parameters. This paper considers a simple demographic model of allopatric divergence between two populations, in which one of the population is hypothesized to have experienced a founder event, or population bottleneck. A large resequencing data set from human populations is summarized by the joint frequency spectrum, which is a matrix of the genomic frequency spectrum of derived base frequencies in two populations. A Bayesian Metropolis-coupled Markov chain Monte Carlo (MCMCMC method for parameter estimation is developed that uses both composite and likelihood methods and is applied to the three different pairwise combinations of the human population resequence data. The accuracy of the method is also tested on data sets sampled from a simulated population model with known parameters. Results The Bayesian MCMCMC method also estimates the ratio of effective population size for the X chromosome versus that of the autosomes. The method is shown to estimate, with reasonable

    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.

  3. Serum bilirubin value predicts hospital admission in carbon monoxide-poisoned patients. Active player or simple bystander?

    Directory of Open Access Journals (Sweden)

    Gianfranco Cervellin

    Full Text Available OBJECTIVES: Although carbon monoxide poisoning is a major medical emergency, the armamentarium of recognized prognostic biomarkers displays unsatisfactory diagnostic performance for predicting cumulative endpoints. METHODS: We performed a retrospective and observational study to identify all patients admitted for carbon monoxide poisoning during a 2-year period. Complete demographical and clinical information, along with the laboratory data regarding arterial carboxyhemoglobin, hemoglobin, blood lactate and total serum bilirubin, was retrieved. RESULTS: The study population consisted of 38 poisoned patients (23 females and 15 males; mean age 39±21 years. Compared with discharged subjects, hospitalized patients displayed significantly higher values for blood lactate and total serum bilirubin, whereas arterial carboxyhemoglobin and hemoglobin did not differ. In a univariate analysis, hospitalization was significantly associated with blood lactate and total serum bilirubin, but not with age, sex, hemoglobin or carboxyhemoglobin. The diagnostic performance obtained after combining the blood lactate and total serum bilirubin results (area under the curve, 0.90; 95% CI, 0.81-0.99; p<0.001 was better than that obtained for either parameter alone. CONCLUSION: Although it remains unclear whether total serum bilirubin acts as an active player or a bystander, we conclude that the systematic assessment of bilirubin may, alongside lactate levels, provide useful information for clinical decision making regarding carbon monoxide poisoning.

    Brain derived neurotrophic factor (BDNF), which has been implicated in the pathogenesis of schizophrenia, has been recently shown to be involved in the regulation of metabolism and energy homeostasis. This study seeks to examine the relationship between BDNF, metabolic indices and cardiovascular (CVD) risk in patients with schizophrenia. Medical histories, demographic information and anthropometric measurements were collected and analyzed from 61 participants with schizophrenia. Fasting glucose and lipids were measured in a central laboratory, and serum BDNF was analyzed using commercially available enzyme-linked immunosorbent assay (ELISA). The 10-year CVD risk for each participant was computed using the Framingham risk score (FRS). Linear regressions were performed to examine the relationships between serum BDNF with body mass index (BMI), blood pressure (BP), triglycerides (TG), total cholesterol, high-density lipoprotein cholesterol (HDL-C) and glucose. To examine the relationship between serum BDNF and FRS, serum BDNF was categorized into quartiles, and a multiple regression was performed. After adjusting for age, gender and current smoking status, diastolic BP (dBP) (p=0.045) and TG (p=0.015) were found to be significantly associated with serum BDNF. Participants in the highest quartile of serum BDNF had a 3.3 times increase in FRS over those in the lowest quartile. Our findings support the possible regulatory role of BDNF in metabolism and cardiovascular homeostasis among patients with schizophrenia similar to that observed among the non-mentally ill. Serum BDNF not only present itself as a candidate biomarker of schizophrenia but also might be a viable marker of metabolic co-morbidities associated with schizophrenia.

    This study aimed to evaluate associations between exposure to a group of persistent organic pollutants, measured in both adipose tissue and serum samples from breast cancer patients, and a set of tumor prognostic markers. The study population comprised 103 breast cancer patients recruited in Granada, Southern Spain. Data for tumor prognostic markers were retrieved from hospital clinical records and socio-demographic information was gathered by questionnaire. Persistent organic pollutants were quantified by gas chromatography with electron capture detection. Exposure levels were categorized in quartiles, and associations were evaluated using unconditional logistic regression. Adipose tissue HCB concentrations were associated positively with ER and PR expression (p-trends = 0.044 and 0.005, respectively) and negatively with E-Cadherin and p53 expression (p-trends = 0.012 and 0.027, respectively). PCB-180 adipose tissue concentrations were positively associated with HER2 expression (p-trend = 0.036). Serum PCB-138 concentrations were positively associated with ER and PR expression (p-trends = 0.052 and 0.042, respectively). The risk of p53 expression was higher among women in the lowest quartile of serum PCB-138 concentrations, but no significant trend was observed (p-trend = 0.161). These findings indicate that human exposure to certain persistent organic pollutants might be related to breast cancer aggressiveness. We also highlight the influence on exposure assessment of the biological matrix selected, given that both serum and adipose tissue might yield relevant information on breast cancer prognosis. - Highlights: • The role of POP exposure on the pathogenesis breast cancer is still controversial. • POPs were analyzed in serum and adipose tissue from breast cancer patients. • POP concentrations were associated with breast cancer prognostic markers. • POPs in serum and adipose tissue of breast cancer patients may provide different clues.

  7. Bias and ignorance in demographic perception.

    Landy, D; Guay, B; Marghetis, T

    2017-08-31

    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.

    Full Text Available Vast records of our everyday interests and concerns are being generated by our frequent interactions with the Internet. Here, we investigate how the searches of Google users vary across U.S. states with different birth rates and infant mortality rates. We find that users in states with higher birth rates search for more information about pregnancy, while those in states with lower birth rates search for more information about cats. Similarly, we find that users in states with higher infant mortality rates search for more information about credit, loans and diseases. Our results provide evidence that Internet search data could offer new insight into the concerns of different demographics.

    Science.gov (United States)

    Forest, Benjamin

    2005-10-25

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

    Ragozzine, Darin; Conaway, James L.; MacDonald, Mariah G.; Sallee, Victor

    2016-10-01

    NASA's Kepler Space Telescope has identified ~700 systems of multiple transiting exoplanets containing ~1700 planets. Most of these multi-transiting systems have 3-5 planets small planets with periods of roughly 5-50 days and are known as Systems with Tightly-spaced Inner Planets (STIPs). These information-rich exoplanetary systems have precisely measured period ratios which allows for the identification and characterization of orbital mean motion resonances. Improved understanding of the resonant populations will reveal much about the formation and evolution of planetary systems. Lissauer, Ragozzine, et al. 2011 found that most Kepler systems were not in resonance, but that there was a small excess of planets wide of resonance. We present new analyses that rigorously identify the frequency of planets in multiple resonances (including three-body resonances) and thus identify many specific new results on the demographics of resonances. We also show that the apparent over-abundance of resonances can be attributed to a difference in inclinations (potentially from dissipation) with implications for the true underlying frequency of resonant systems. We compare the period ratio distribution of Kepler (corrected for inclination biases) to Radial Velocity (RV) surveys and conclude that RV systems are often missing small intermediate planets. This has serious implications for the completeness of RV identification of planets in STIPs.

    Primary immunodeficiency disorders are a recognized public health problem worldwide. The prototype of these conditions is X-linked agammaglobulinemia (XLA) or Bruton's disease. XLA is caused by mutations in Bruton's tyrosine kinase gene (BTK), preventing B cell development and resulting in the almost total absence of serum immunoglobulins. The genetic profile and prevalence of XLA have not previously been studied in Eastern and Central European (ECE) countries. We studied the genetic and demographic features of XLA in Belarus, Croatia Hungary, Poland, Republic of Macedonia, Romania, Russia, Serbia, Slovenia, and Ukraine. We collected clinical, immunological, and genetic information for 122 patients from 109 families. The BTK gene was sequenced from the genomic DNA of patients with a high susceptibility to infection, almost no CD19(+) peripheral blood B cells, and low or undetectable levels of serum immunoglobulins M, G, and A, compatible with a clinical and immunological diagnosis of XLA. BTK sequence analysis revealed 98 different mutations, 46 of which are reported for the first time here. The mutations included single nucleotide changes in the coding exons (35 missense and 17 nonsense), 23 splicing defects, 13 small deletions, 7 large deletions, and 3 insertions. The mutations were scattered throughout the BTK gene and most frequently concerned the SH1 domain; no missense mutation was detected in the SH3 domain. The prevalence of XLA in ECE countries (total population 145,530,870) was found to be 1 per 1,399,000 individuals. This report provides the first comprehensive overview of the molecular genetic and demographic features of XLA in Eastern and Central Europe.

    Riffe, Tim; Schöley, Jonas; Villavicencio, Francisco

    Demographic thought and practice is largely conditioned by the Lexis diagram, a two-dimensional graphical representation of the identity between age, period, and birth cohort. This relationship does not account for remaining years of life or other related time measures, whose use in demographic...... research is both underrepresented and incompletely situated. We describe a three-dimensional relationship between six different measures of demographic time: chronological age, time to death, lifespan, time of birth, time of death, and period. We describe four identities among subsets of these six measures...

    Vaccination against common pathogens, such as influenza, is recommended for patients with systemic lupus erythematosus (SLE) to decrease infections and improve health. However, most reports describing the vaccination response are limited to evaluations of SLE patients with quiescent disease. This study focuses on understanding the clinical, serologic, therapeutic, and demographic factors that influence the response to influenza vaccination in SLE patients with a broad range of disease activity. Blood specimens and information on disease activity were collected from 72 patients with SLE, at baseline and at 2, 6, and 12 weeks after influenza vaccination. Influenza-specific antibody responses were assessed by determining the total serum antibody concentration (B(max)), relative affinity (K(a)), and level of hemagglutination inhibition in the plasma. Using a cumulative score, the patients were evenly divided into groups of high or low vaccine responders. Autoantibody levels were evaluated at each time point using immunofluorescence tests and standard enzyme-linked immunosorbent assays. Compared to high responders, low responders to the vaccine were more likely to have hematologic criteria (P = 0.009), to have more American College of Rheumatology classification criteria for SLE (P = 0.05), and to be receiving concurrent prednisone treatment (P = 0.04). Interestingly, European American patients were more likely to be low responders than were African American patients (P = 0.03). Following vaccination, low responders were more likely to experience disease flares (P = 0.01) and to have increased titers of antinuclear antibodies (P = 0.04). Serum interferon-α activity at baseline was significantly higher in patients in whom a flare occurred after vaccination compared to a matched group of patients who did not experience a disease flare (P = 0.04). Ancestral background, prednisone treatment, hematologic criteria, and evidence of increased likelihood of disease flares were

    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.

  4. 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.

    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

    Demographic heterogeneity—variation among individuals in survival and reproduction—is ubiquitous in natural populations. 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. Recent research ...

  9. Two centuries of demographic change in Canada

    Directory of Open Access Journals (Sweden)

    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

    To evaluate for the first time the longitudinal relationship between serum uric acid concentrations and risk of frailty. Prospective cohort study of 2198 non-institutionalized individuals aged ≥60years recruited in 2008-2010. At baseline, information was obtained on socio-demographic factors, health behaviors and morbidity, while serum uric acid was determined in 12-h fasting blood samples. Study participants were followed-up through 2012 to assess incident frailty, defined as ≥2 of the following 4 Fried criteria: exhaustion, muscle weakness, low physical activity, and slow walking speed. During a mean 3.5-year follow-up, 256 cases of incident frailty were identified. After multivariate adjustment, the odds ratios (95% confidence interval) of frailty comparing the second and third tertiles of uric acid to the lowest tertile were, respectively: 1.18 (0.83-1.68) and 1.57 (1.11-2.22); p-linear trend=0.01. The corresponding result for a 1mg/dL increase in serum uric acid concentration was 1.12 (1.00-1.24). Similar associations were observed across subgroups defined by sex, age, body mass index, and physical activity. As regards each frailty component, the odds ratios (95% confidence interval) per 1mg/dL increase in serum uric acid were 1.10 (0.99-1.23) for low physical activity, 1.08 (0.95-1.23) for low walking speed, 1.08 (0.67-1.73) for exhaustion and 0.91 (0.81-1.02) for weakness. Serum uric acid concentrations are positively associated with the risk of frailty in older adults. Further studies are needed to evaluate whether specific dietary recommendations or pharmacological strategies aimed at lowering serum uric acid would be beneficial to prevent the development of this syndrome.

    The Chi Linh Health and Demographic Surveillance System (CHILILAB HDSS) is the only health and demographic surveillance system (HDSS) in an urbanizing area of the Chi Linh district of Hai Duong, a northern province of Vietnam. It is one of the few field laboratories in the world that links operational research and health interventions with field training. The CHILILAB HDSS provides longitudinal data on demographic and health indicators for the community of Chi Linh. In 2012, when the CHILILAB HDSS included 57,561 people from 17 993 households in 3 towns and 4 communes, it used structured questionnaires to collect information on population changes (birth, death, migration, marriage, and pregnancy) in the community. As of December 2012, 5 rounds of a baseline survey and 17 periodic update surveys or re-enumeration surveys had been conducted. In addition, several specialized public-health research projects, focused particularly on adolescent health, have been implemented by the CHILILAB HDSS. The information that the CHILILAB HDSS has gathered provides a picture of the health status of the population and socio-economic situation in Chi Linh district. The contact person for data sharing is the director of the CHILILAB (E-mail: thb@hsph.edu.vn).

    2011-06-01

    Full Text Available The purpose of this study was to examine student entry into a campus recreation center based on seven demographics (gender, ethnicity, age, class standing, intercollegiate athlete vs. non-athlete, students with self-reported disability vs. non-disability, and campus residence in order to determine who would be most likely to enter the recreation center. Subjects were from a mid-western, four year state-assisted institution with combined enrollment of 23,932 undergraduate and graduate students. Of the 23,932 enrolled, 14,032 students were examined in this study. Information on student entry to the recreation center was collected through the university’s student information system. Data was analyzed and interpreted using chi-square analysis. Results of the study show statistically significant differences in the demographics except the student disability demographic. More males than females, more African Americans than other ethnicities, more traditionally aged (18-25 students than non-traditional students, more underclassmen than seniors, more athletes and non-athletes, more residents than commuters were likely to enter the campus recreation center. The findings in this study could be used by collegiate recreational sport directors and administrators, in the United States and internationally, for future ideas about programming in similar recreation settings.

    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

    Full Text Available Over the last few years, many European and North American countries have reported a high rate of disorders (mortality, dwindling and disappearance affecting honeybee colonies (Apis mellifera. Although beekeeping has become an increasingly professional activity in recent years, the beekeeping industry remains poorly documented in Europe. The European Union Reference Laboratory for Honeybee Health sent a detailed questionnaire to each Member State, in addition to Kosovo and Norway, to determine the demographics and state of their beekeeping industries. Based on data supplied by the National Reference Laboratory for honeybee diseases in each European country, a European database was created to describe the beekeeping industry including the number and types of beekeepers, operation size, industry production, and health (notifiable diseases, mortalities. The total number of beekeepers in Europe was estimated at 620,000. European honey production was evaluated at around 220,000 tons in 2010. The price of honey varied from 1.5 to 40 €/kg depending on the country and on the distribution network. The estimated colony winter mortality varied from 7 to 28% depending on the country and the origin of the data (institutional survey or beekeeping associations. This survey documents the high heterogeneity of the apicultural industry within the European Union. The high proportion of non-professional beekeepers and the small mean number of colonies per beekeeper were the only common characteristics at European level. The tremendous variation in European apicultural industries has implication for any comprehensive epidemiological or economic analysis of the industry. This variability needs to be taken into account for such analysis as well as for future policy development. The industry would be served if beekeeping registration was uniformly implemented across member states. Better information on the package bee and queen production would help in understanding

    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.

    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.

    Background/Aim: Studies have indicated a relationship between either gene polymorphism or in vivo B vitamins’ nutritional status with cognition in the elderly. However, the combined effects of MTHFR and SLC19A1gene polymorphism with serum folate and vitamin B12 levels on cognition in Chinese adult population remain unclear. Methods: Demographic information of 426 Chinese adults aged from 55 to 90 were collected by a well designed self-administered questionnaire. The Montreal Cognitive Assessment test was utilized to evaluate the cognition status of the participants. MTHFR and SLC19A1 genotyping was analyzed using polymerase chain reaction-ligase detection reaction (PCR- LDR) method. Serum folate, vitamin B12 and homocysteine (Hcy) levels were detected by commercial assay kits. Pearson’s correlation was used for data analyses and statistical significance was set at p vitamin B12 (r = −0.292) levels. The negative correlation found between serum Hcy levels and attention ability was observed in all 426 studied subjects (r = −0.122). Subjects with MTHFR 677 T/T and 1298 A/A genotypes demonstrated a higher serum Hcy levels (p vitamin B12. Conclusion: Cognition of adults was associated with MTHFR, SLC19A1 gene polymorphism and serum Hcy levels. This study clearly establishes a combined effect of MTHFR gene polymorphism and serum B vitamins levels on cognition in Chinese adults. PMID:27783031

    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.

    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.

    Full Text Available ApoE gene polymorphism has been reportedly associated with serum lipids and cognition. However, very few studies have explored the combined effects of ApoE gene polymorphism and gender on serum lipid profile with subsequent impacts on cognition in Chinese population. A total of 1,000 Chinese community dwellers aged 55 years and above were recruited in this cross-sectional study. Demographic information of the participants was collected using well designed self-administered questionnaires. The Montreal Cognitive Assessment (MoCA test was employed to evaluate the cognitive status of the participants. Semi-quantitative food frequency questionnaire (FFQ was used to obtain the dietary intake information. Fasting venous blood samples were taken for ApoE genotyping and serum lipid measurements. Significant gender differences in cognition, serum lipid profile and dietary fat-rich foods consumption were observed (p < 0.05. Cognition of the subjects was found to be associated with ApoE genotypes (p < 0.05. ApoE rs429358 and rs7412 variants demonstrated a significant effect on cognitive performance in the male subjects; especially within the attention and language cognitive domains as well as the total MoCA score (p < 0.05, respectively. Serum lipid profile and cognition of Chinese adults are significantly linked with gender and ApoE genetic polymorphism. The ApoE variant rs429358 is found to be notably associated with cognition in aging male Chinese population.

    Full Text Available This paper presents a situational analysis of the level of life safety in the field of demographic regions of the Ural Federal District. The analysis is based on data from the Federal Statistics and covers the period 2000-2010. We have developed a system of indicators for evaluating safety in the demographic sphere. We set the main threats to the social and economic stability in the regions. The system of thresholds includes three blocks: the reproduction of the population, marriage and family relationships and health. We have presented a quantitative description of the main threats. Identified priority areas of social protection, providing increased stability of the regional socio-economic development, reducing the likelihood of social conflicts and improve the demographic situation.

    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: Low serum 25-hydroxy vitamin D (25(OHD has been shown to correlate with an increased risk of type 2 diabetes mellitus (T2DM. The objective of this study was to investigate the association between serum 25(OHD and glycemic and inflammatory markers in non-obese patients with T2DM. Methods: Eighty-four non-obese patients with T2DM were recruited in this cross-sectional study. Demographic, anthropometric, and dietary information was obtained from all the participants. The serum concentrations of glucose, HbA1C, insulin, 25(OHD, and inflammatory markers including tumor necrosis factor-alpha (TNF-α and high sensitive C-reactive protein (hs-CRP were measured. A homeostatic model of insulin resistance (HOMA-IR was also evaluated. Results: The mean serum concentration of 25(OHD was 11.01±5.55 ng/mL. Severe deficiency, deficiency, and insufficiency of vitamin D were detected in 60.71%, 35.72%, and 3.57% of the participants, respectively. The results showed that those in the lowest group of serum 25(OHD had significantly higher TNF-α than did those in the highest group (P=0.026. Although the association between serum 25(OHD and fasting blood sugar and TNF-α was statistically significant (P=0.049 and P=0.044, respectively, the other glycemic markers and hs-CRP did not have any significant relationships with 25(OHD. Conclusion: According to the high prevalence of vitamin D deficiency in the diabetic patients and the inverse relationship between serum 25(OHD and fasting blood sugar and TNF-α in this study, vitamin D status may be a determining factor of systemic inflammation in patients with T2DM. Further studies with larger sample sizes are suggested in this regard.

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

    To explore the distribution of New Zealanders' support towards the legalisation of euthanasia and examine demographic and psychological factors associated with these attitudes. 15,822 participants responded to the 2014/15 New Zealand Attitudes and Values Study (NZAVS) survey. This survey included an item on people's attitudes towards euthanasia, and information on their demographic and psychological characteristics. The majority of New Zealanders expressed support for euthanasia, which was assessed by asking "Suppose a person has a painful incurable disease. Do you think that doctors should be allowed by law to end the patient's life if the patient requests it?" Non-religious, liberal, younger, employed, non-parents and those living in rural areas were more supportive. Those of Pacific or Asian ethnicity, with lower income and higher deprivation, education and socio-economic status were less supportive. Furthermore, those high on extraversion, conscientiousness and neuroticism showed more support, while those high on agreeableness and honesty-humility exhibited less support. There is strong public support for euthanasia when people are asked whether doctors should be allowed by law to end the life of a patient with a painful incurable disease upon their request. There are reliable demographic and personality differences in support for euthanasia.

  14. Inferring Demographic History Using Two-Locus Statistics.

    2017-06-01

    Population demographic history may be learned from contemporary genetic variation data. Methods based on aggregating the statistics of many single loci into an allele frequency spectrum (AFS) have proven powerful, but such methods ignore potentially informative patterns of linkage disequilibrium (LD) between neighboring loci. To leverage such patterns, we developed a composite-likelihood framework for inferring demographic history from aggregated statistics of pairs of loci. Using this framework, we show that two-locus statistics are more sensitive to demographic history than single-locus statistics such as the AFS. In particular, two-locus statistics escape the notorious confounding of depth and duration of a bottleneck, and they provide a means to estimate effective population size based on the recombination rather than mutation rate. We applied our approach to a Zambian population of Drosophila melanogaster Notably, using both single- and two-locus statistics, we inferred a substantially lower ancestral effective population size than previous works and did not infer a bottleneck history. Together, our results demonstrate the broad potential for two-locus statistics to enable powerful population genetic inference. Copyright © 2017 by the Genetics Society of America.

    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.

    The causes of death have changed with regard to the epidemiological and demographic events in society. There is no evidence of prior research into the epidemiological transition in Turkey. This transition in Turkey should be observed starting with the Ottoman Empire period (19th to early 20th century). However, information about the Ottoman Empire is quite limited. To discuss the epidemiological and demographic transitions in Turkey, using demographic, educational and urbanization data in our present study. A descriptive archive study. Mortality statistics dating from 1931 and published by the Turkish Statistical Institute were analysed, and the causes of death were coded and classified according to ICD-10. Other data were obtained from the published reports and studies regarding the issue. In the 1930s, Turkey's life expectancy was low (aged 40 years), fertility and mortality rates were high (respectively 45% and 31%), and the main causes of death were infectious diseases. Nowadays, life expectancy is close to 80 years, the total fertility rate has dropped to 2.1 per woman, and the main causes of death are chronic diseases and cancer. The population rate in the urban areas has increased steadily from 24.2% in 1927 to 77.3% in 2012. level of education has also increased during this period. In 1935, less than 10% of women were literate, and in 2013 90% were literate. Qualitative and quantitative increase have been observed in the presentation and access of healthcare services compared to the early years of the Republic. Turkey has been undergoing a modernization period in the last 200 years, and it is believed that the epidemiological and demographic transitions result from this period. This process has led to urbanization and an increase in the level of education, as well as a decrease in premature deaths, lower fertility rates, and an increase in the elderly population and chronic diseases. It is therefore our conclusion that Turkey needs policies regarding the

    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

  18. Serum Antibody Repertoire Profiling Using In Silico Antigen Screen.

    Full Text Available Serum antibodies are valuable source of information on the health state of an organism. The profiles of serum antibody reactivity can be generated by using a high throughput sequencing of peptide-coding DNA from combinatorial random peptide phage display libraries selected for binding to serum antibodies. Here we demonstrate that the targets of immune response, which are recognized by serum antibodies directed against sequential epitopes, can be identified using the serum antibody repertoire profiles generated by high throughput sequencing. We developed an algorithm to filter the results of the protein database BLAST search for selected peptides to distinguish real antigens recognized by serum antibodies from irrelevant proteins retrieved randomly. When we used this algorithm to analyze serum antibodies from mice immunized with human protein, we were able to identify the protein used for immunizations among the top candidate antigens. When we analyzed human serum sample from the metastatic melanoma patient, the recombinant protein, corresponding to the top candidate from the list generated using the algorithm, was recognized by antibodies from metastatic melanoma serum on the western blot, thus confirming that the method can identify autoantigens recognized by serum antibodies. We demonstrated also that our unbiased method of looking at the repertoire of serum antibodies reveals quantitative information on the epitope composition of the targets of immune response. A method for deciphering information contained in the serum antibody repertoire profiles may help to identify autoantibodies that can be used for diagnosing and monitoring autoimmune diseases or malignancies.

    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.

    Background Humans are exposed to persistent organic pollutants (POPs) through various routes, including consumption of contaminated food and accidental ingestion of settled dust. Objectives We aimed to identify key routes of exposure to organochlorine pesticides, polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs) in California women of reproductive age. Methods Blood was collected from 48 mothers participating in the California Childhood Leukemia Study from 2006–2007 and analyzed for POPs using gas chromatography-mass spectrometry. Multivariable linear regression models of natural-log transformed serum concentrations were used to identify determinants of exposure from available questionnaire information on dietary habits, reproductive history, and demographic characteristics, as well as vacuum cleaner dust-POP levels. Results After adjusting for blood lipid levels, age, body mass index, cumulative lactation, and sampling date, serum concentrations of multiple major PCBs were positively associated with fish consumption, but not dust-PCB levels. After adjusting for blood lipid levels, Hispanic ethnicity, country of origin, and household annual income, serum concentrations of multiple major PBDEs were positively associated with dust-PBDE levels. Conclusions Our findings suggest that the relative contribution of specific exposure routes to total POP intake varies by chemical class, with dust being a relatively important source of PBDEs and diet being a relatively important source of PCBs.

    Oxidative stress inhibits albumin's ability to complex with cobalt. Feline serum-cobalt binding has not been described. The objective was to develop a cobalt binding test for use with feline serum, and correlate the results with other biochemical and cellular constituents in blood, and with clinical diseases of cats. A colorimetric test of cobalt binding, based on the oxidation-reduction reaction of Co(+2) and dithiothreitol, was developed using feline serum. The test was used to measure cobalt binding in stored serum from 176 cats presented to the University of Illinois Veterinary Teaching Hospital for a variety of disease conditions. Time-matched hematology and biochemical data, and clinical information, were obtained from the medical record of each cat and correlated with the serum-cobalt binding results. Serial dilution of feline serum with phosphate-buffered saline resulted in a highly linear decrease in serum-cobalt binding (r(2)  = .9984). Serum-cobalt binding of the clinical samples also correlated with albumin concentrations in a stepwise linear regression model (r(2)  = .425), and both cobalt binding and albumin were significantly decreased in cases of inflammation. Albumin and cobalt binding also shared significant correlations with several erythron variables, and serum concentration of total calcium and bilirubin. The correlation of cobalt binding measured by a colorimetric test with albumin concentration in the clinical samples and with serum dilution is consistent with feline albumin-cobalt complex formation. Hypoalbuminemia is the likely cause of reduced serum-cobalt binding in inflammation and the correlations observed between cobalt binding and other variables. © 2015 American Society for Veterinary Clinical Pathology.

    Full Text Available The purpose of the study is to research birth tourism issue. The article gives the socio-demographic and statistical aspects of research problems of birth inbound tourism in the Russian Federation. Following the literature analysis, the degree of study for birth tourism lags behind its actual size. Currently, the media has accumulated a significant amount of information on birth tourism in Russia, that requires processing, systematization and understanding that can and should become an independent area of study of sociologists and demographers to develop recommendations for the management of socio-demographic processes in birth tourism in our country. It is necessary to identify the problems that will inevitably arise. At present, this process is almost not regulated.These problems are complex, it requires the joint efforts of sociologists and demographers. However, it is impossible to obtain reliable results and to develop management decisions without attention to the statistical aspect of this problem. It is necessary to create methodological support for collecting and information processing and model development of the birth tourism. At the initial stage it is necessary to identify the direction and objectives of the analysis to determine the factors in the development of this process, to develop a hierarchical system of statistical indicators, to receive the information, needed for calculating of specific indicators.The complex research of the birth tourism issues should be based on the methodology of sociology, demography and statistics, including statistical observation, interviews with residents, structure analysis and birth tourism concentration in the country, the analysis of the dynamics, classification of factors and reasons, the grouping of regions for the development of the studied processes and, of course, the development of economic-statistical indicators.The article reveals the problem of the significant influence of the

    Full Text Available Abstract Background The aim of this study is to evaluate the association between acute serum creatinine changes in acute renal failure (ARF, before specialized treatment begins, and in-hospital mortality, recovery of renal function, and overall mortality at 6 months, on an equal degree of ARF severity, using the RIFLE criteria, and comorbid illnesses. Methods Prospective cohort study of 1008 consecutive patients who had been diagnosed as having ARF, and had been admitted in an university-affiliated hospital over 10 years. Demographic, clinical information and outcomes were measured. After that, 646 patients who had presented enough increment in serum creatinine to qualify for the RIFLE criteria were included for subsequent analysis. The population was divided into two groups using the median serum creatinine change (101% as the cut-off value. Multivariate non-conditional logistic and linear regression models were used. Results A ≥ 101% increment of creatinine respect to its baseline before nephrology consultation was associated with significant increase of in-hospital mortality (35.6% vs. 22.6%, p Conclusion In this cohort, patients who had presented an increment in serum level of creatinine of ≥ 101% with respect to basal values, at the time of nephrology consultation, had increased mortality rates and were discharged from hospital with a more deteriorated renal function than those with similar Liano scoring and the same RIFLE classes, but with a

    This study aimed to evaluate associations between exposure to a group of persistent organic pollutants, measured in both adipose tissue and serum samples from breast cancer patients, and a set of tumor prognostic markers. The study population comprised 103 breast cancer patients recruited in Granada, Southern Spain. Data for tumor prognostic markers were retrieved from hospital clinical records and socio-demographic information was gathered by questionnaire. Persistent organic pollutants were quantified by gas chromatography with electron capture detection. Exposure levels were categorized in quartiles, and associations were evaluated using unconditional logistic regression. Adipose tissue HCB concentrations were associated positively with ER and PR expression (p-trends=0.044 and 0.005, respectively) and negatively with E-Cadherin and p53 expression (p-trends=0.012 and 0.027, respectively). PCB-180 adipose tissue concentrations were positively associated with HER2 expression (p-trend=0.036). Serum PCB-138 concentrations were positively associated with ER and PR expression (p-trends=0.052 and 0.042, respectively). The risk of p53 expression was higher among women in the lowest quartile of serum PCB-138 concentrations, but no significant trend was observed (p-trend=0.161). These findings indicate that human exposure to certain persistent organic pollutants might be related to breast cancer aggressiveness. We also highlight the influence on exposure assessment of the biological matrix selected, given that both serum and adipose tissue might yield relevant information on breast cancer prognosis.

    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.

    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.

  14. 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.

    2012-01-01

    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 ...

    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

    The link between the mortality and epidemiological transitions is used to identify the effect of the former on the fertility transition: a mortality transition that is not accompanied by improving morbidity causes slower demographic and economic change. In a model where children may die from infectious disease, childhood health affects human capital and noninfectious-disease-related adult mortality. When child mortality falls from lower prevalence, as it did in western Europe, labor productiv...

    The demographic characteristics of those obliged to live away from their families because of the distance between their normal homes and places of work or education in Japan are described. Data are from a variety of official and other sources. The author notes that such persons are generally male. Factors affecting the growth of this phenomenon in Japan are the concept of lifetime employment with the same company and the popularity of sending children away to school.

  4. Piezoelectric microcantilever serum protein detector

    Science.gov (United States)

    Capobianco, Joseph A.

    The development of a serum protein detector will provide opportunities for better screening of at-risk cancer patients, tighter surveillance of disease recurrence and better monitoring of treatment. An integrated system that can process clinical samples for a number of different types of biomarkers would be a useful tool in the early detection of cancer. Also, screening biomarkers such as antibodies in serum would provide clinicians with information regarding the patient's response to treatment. Therefore, the goal of this study is to develop a sensor which can be used for rapid, all-electrical, real-time, label-fee, in-situ, specific quantification of cancer markers, e.g., human epidermal receptor 2 (Her2) or antibodies, in serum. To achieve this end, piezoelectric microcantilever sensors (PEMS) were constructed using an 8 mum thick lead magnesium niobate-lead titanate (PMN-PT) freestanding film as the piezoelectric layer. The desired limit of detection is on the order of pg/mL. In order to achieve this goal the higher frequency lateral extension modes were used. Also, as the driving and sensing of the PEMS is electrical, the PEMS must be insulated in a manner that allows it to function in aqueous solutions. The insulation layer must also be compatible with standardized bioconjugation techniques. Finally, detection of both cancer antigens and antibodies in serum was carried out, and the results were compared to a standard commercialized protocol. PEMS have demonstrated the capability of detecting Her2 at a concentration of 5 pg/mL in diluted human serum (1:40) in less than 1 hour. The approach can be easily translated into the clinical setting because the sensitivity is more than sufficient for monitoring prognosis of breast cancer patients. In addition to Her2 detection, antibodies in serum were assayed in order to demonstrate the feasibility of monitoring the immune response for antibody-dependent cellular cytotoxicity (ADCC) in patients on antibody therapies

  5. 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.

    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.

  7. Development of reprogenetics and its demographic aspects

    Directory of Open Access Journals (Sweden)

    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.

    Full Text Available Background: Developing appropriate and equitable policies for older people in Africa requires accurate and reliable data. It is unclear whether existing data can accurately assess older African population structures, let alone provide the detailed information needed to inform policy decision-making. Objective: To evaluate the quality of nationally representative data on older Africans through examining the accuracy of age data collected from different sources. Methods: To measure the accuracy of age reporting overall we calculate Whipple's Index, and a modified Whipple's Index for older adults, using the single year age-sex distributions from (a the household roster of 17 Demographic and Health Surveys (DHS, (b the censuses of 12 of these countries, and (c the Living Standards Measurement Study (LSMS for Ethiopia and Niger. We compare reported sex ratios by age. Results: The quality of age data is very poor for most countries outside Southern Africa, especially for older adults. In some Sahelian countries DHS surveys appear to omit a considerable proportion of older women. Data on population structure of older people by age and sex produced by the DHS and the census are inconsistent and contradictory. Conclusions: Different field methodological approaches generate contradictory data on older Africans. With the exception of Southern Africa, it is impossible to assess accurately the basic demographic structure of the older population. The data available are so problematic that any conclusions about age-related health and welfare and their evolution over time and space are potentially compromised. This has ramifications for policymakers and practitioners who demand, fund, and depend on large-scale demographic data sources. Contribution: The paper highlights a number of problems with data on older Africans, beyond the well-known issues of age heaping. In doing so it contributes to general understanding of the limitations of existing demographic data

    To assist in developing uniform reporting of vital events among the fifty states, Puerto Rico, and the Virgin Islands, the United States government prepares standard certificates of birth, fetal death, death, marriage, and divorce. These model forms are revised, with the assistance of the states, approximately every ten years. Revisions are now being prepared by the National Center for Health Statistics which will become effective beginning January 1, 1968. Important new source material for demography will be introduced.Most changes will appear in the Standard Certificate of Live Birth and in the Standard Certificate of Fetal Death. An item on education of father and mother will provide detailed national data on education and fertility. The date of the last live birth to the mother and the date of the last fetal death will provide information on previous pregnancy outcome and on child-spacing. The recording of state file numbers for mates born alive and dead in the same delivery will make it easier to match live birth and fetal death certificates for the preparation of detailed tabulations on multiple births. Several new items related to maternal and child health have also been added. No significent changes were planned for the Standard Certificate of Death.The Standard Certificate of Marriage will include as new items the education of the bride and groom, the date on which the last marriage, if any, ended, and specification of the officiant as a religious or civil official. The Standard Certificate of Divorce or Annulment will obtain information on the education of husband and wife, the approximate date on which the couple separated, the mode of dissolution of the previous marriage, and the total number of living children. It is anticipated that most of the new items will be included in the certificates of all the states. The National Center for Health Statistics will provide detailed tabulations related to these items, beginning with data year 1968.Demographers

  14. Demographic Transformations of the Russian Regional Space

    2015-07-01

    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

  15. Quality of demographic data in GGS Wave 1

    Directory of Open Access Journals (Sweden)

    Jorik Vergauwen

    2015-03-01

    Full Text Available Background: A key feature of the Generations & Gender Programme (GGP is that longitudinal micro-data from the Generations and Gender Surveys (GGS can be combined with indicators from the Contextual Database (CDB that provide information on the macro-level context in which people live. This allows researchers to consider the impact of socio-cultural, economic, and policy contexts on changing demographic behaviour since the 1970s. The validity of longitudinal analyses combining individual-level and contextual data depends, however, on whether the micro-data give a correct account of demographic trends after 1970. Objective: This article provides information on the quality of retrospective longitudinal data on first marriage and fertility in the first wave of the GGS. Methods: Using the union and fertility histories recorded in the GGS, we compare period indicators of women's nuptiality and fertility behaviour for the period 1970-2005 and cohort indicators of nuptiality and fertility for women born after 1925 to population statistics. Results: Results suggest that, in general, period indicators estimated retrospectively from the GGS are fairly accurate from the 1970s onwards, allowing exceptions for specific indicators in specific countries. Cohort indicators, however, were found to be less accurate for cohorts born before 1945, suggesting caution when using the GGS to study patterns of union and family formation in these older cohorts. Conclusions: The assessment of the validity of demographic data in the GGS provides country-specific information on time periods and birth cohorts for which GGS estimates deviate from population statistics. Researchers may use this information to decide on the observation period or cohorts to include in their analysis, or use the results as a starting point for a more detailed analysis of item nonresponse in union and fertility histories, which may further improve the quality of GGS estimates, particularly for these

    As many as 2247 patients with different clinical forms of diphtheria were examined. Antidiphtheric serum (ADS) was administered in 1556 children, the dosage being determined by condition of the patient. Serum sickness developed at day 7 to 9 in 24 (1.5%); 10 patients were found to run a mild course, 14--moderately severe. 6 patients had allergic reactions: 3--to antibiotic (penicillin), urticaria type, 1--to pertussoid-tetanic anatoxin, 2 had pollinosis-type reaction. Thus, serum sickness has practical value, which fact requires a detailed allergic history together with skin tests to be performed before the administration of ADS.

  20. 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.

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

    Živković, Daniel; Tellier, Aurélien

    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.

    2013-03-01

    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.

    Full Text Available Nearly 25 years ago, a “Zooarchaeology Practitioner Survey” was distributed via conventional mail to individuals in the USA and Canada and received 122 responses over a period of several months in 1991. Now, a revised “Demographics in Zooarchaeology Survey” provides an update to  those data and assesses the current state of the field. The 2014 survey remained open for 3 months and received 288 responses from practitioners worldwide. Global participation was made possible by hosting the survey online. Key findings of the 1991 survey included disparities in employment rank for women despite similar levels of degree level attainment as men, a point which the 2014 survey sought to investigate. This trend appears to persist for those without the PhD and at the highest levels of income for those holding a PhD. In addition, the recent survey asked participants about their racial or ethnic identity in order to evaluate the demographic diversity of the discipline beyond sex, age, and nationality. Data regarding topical and geographic research area were also collected and reflect a subtle bias towards working with mammals and a focus on research questions grounded in prehistory in Europe and North America, followed by Australia and Southwest Asia. Results are compared with those of the earlier survey and membership information from the International Council for Archaeozoology.

    Full Text Available Objective: to analyze the behavior of some demographic characteristics for each department to identify the state of demographic transition and its relationship to the development level. Methodology: descriptive study based on secondary information sources published by the National Statistics Department and the National Planning Department. Results: the global fertility rate of the country was 2.5 in 2005. Chocó reported the highest rate whereas Bogotá reported the lowest. A total of 67% of Colombian states registered higher rates than the average rate in the country. Mortality rate of children in the country was 24.5, with the lowest rates registered in El Valle, Caldas, and Bogotá. The highest rates were registered in Arauca and Chocó. 26.6% of Colombian states show some advance in the demographic transition process. By contrast, 67% of the states are classified as lagged behind. There is a relation between the demographic transition index and the development indicators. Conclusion: Although some departments reach an advanced level of demographic transition, most of them still show high rates of infant mortality or fecundity which keep them behind in this process. Inequalities in living conditions of the country’s departments could be influencing the behavior of the demographic components analyzed.

    Evidence suggests that altered iron metabolism may be associated with oxidative damage to several organ systems, including the eye. Supplementary iron consumption is also associated with greater odds of self-reported glaucoma. To investigate the association between serum ferritin level and the likelihood of a glaucoma diagnosis in a cross-sectional, population-based study. Data were collected from 17,476 participants in the first and second years of the Fifth Korea National Health and Nutrition Examination Survey, a cross-sectional study of the South Korean population conducted from January 1, 2010, through December 31, 2011. Data pertaining to the serum ferritin level were aggregated and divided into quartiles. Demographic, comorbidity, and health-related behavior information was obtained via interview. The presence or absence of glaucoma. The definition of glaucoma was based on criteria established by the International Society of Geographical and Epidemiological Ophthalmology. Participants whose serum ferritin level was greater than 61 ng/mL (to convert to picomoles per liter, multiply by 2.247) had significantly higher odds of a glaucoma diagnosis when compared with those with a level less than 31 ng/mL, after adjustment for potential confounders (ferritin levels of 31-61 ng/mL: odds ratio [OR], 1.17; 95% CI, 0.84-1.62; ferritin levels of 62-112 ng/mL: OR, 1.60; 95% CI, 1.16-2.20; and ferritin levels of 113-3018 ng/mL: OR, 1.89; 95% CI, 1.32-2.72). Our study reveals that a higher serum ferritin level was associated with greater odds of glaucoma in a representative sample of the South Korean population, even at levels normally observed in the general population. This novel finding may help elucidate the pathogenesis and lead to novel therapeutic approaches for glaucomatous disease.

    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. The other four were: level of participation in local activities, degree of involvement in community improvement activities, degree to

    Recent literature on material flow analysis has been focused on quantitative characterization of past material flows. Fewer analyses exist on past and prospective quantification of stocks of materials in-use. Some of these analyses explore the composition of products' stocks, but a focus on the characterization of material stocks and its relation with service delivery is often neglected. We propose the use of the methods of human demography to characterize material stocks, defined herein as stock demographics, exploring the insights that this approach could provide for the sustainable management of materials. We exemplify an application of stock demographics by characterizing the composition and service delivery of iron, steel, and aluminum stocks of cars in Great Britain, 2002-2012. The results show that in this period the stock has become heavier, it is traveling less, and it is idle for more time. The visualization of material stocks' dynamics demonstrates the pace of product replacement as a function of its usefulness and enables the formulation of policy interventions and the exploration of future trends.

    Calcium is an essential element for life and has cerebroprotective property in stroke patients. Low serum calcium levels were found to be related to large hematoma volumes in intracerebral hemorrhagic patients and hemorrhagic transformation in ischemic stroke patients after thrombolysis. However, their impact on hemorrhage-prone small vessel disease represented by cerebral microbleeds (CMBs) is uncertain. We aim to investigate whether low serum calcium levels are associated with presence and location of CMBs.Ischemic stroke patients with atrial fibrillation (AF) and/or rheumatic heart disease admitted to our hospital were consecutively and prospectively enrolled. Demographic and clinical information were collected and analyzed according to the occurrence and location of CMBs, and levels of serum calcium. We used logistic regression analysis to estimate the multivariable adjusted relationship between serum calcium levels and the presence or location of CMBs.Among the 67 patients (28 males; mean age, 67.3 years) in the final analysis, 39 (58.2%) were found to have CMBs. After adjustment for age, sex, smoking habits, drinking habits, and renal impairment, the presence of CMBs and deep CMBs was, respectively, 4.96- and 4.83-fold higher in patients with lower serum calcium levels (≤2.15 mmol/L) than in patients with higher serum calcium levels.Lower serum calcium levels (≤2.15 mmol/L) are independently associated with the presence of CMBs and deep CMBs in ischemic stroke patients with AF and/or rheumatic heart disease, which should be verified and extended in large cohorts, with other types of stroke patients and the general population.

    Psoriasis has been accepted as a systemic disease and it is known to be associated with various disorders including metabolic syndrome. High serum uric acid levels are also associated with the components of metabolic syndrome. In this study, we aimed to determine serum uric acid levels in patients with psoriasis and the association of uric acid levels with disease activity by taking the presence of metabolic syndrome criteria into account, since it is one of the most important factors that affect serum uric acid levels. In this cross-sectional study, we evaluated 70 psoriasis patients and 70 healthy individuals who were matched with the patients according to the presence of metabolic syndrome. We evaluated the demographic features, levels of serum uric acid, Psoriasis Area Severity Index (PASI) scores, presence of psoriatic arthritis, nail involvement, and metabolic syndrome criteria of the patients. Serum uric acid levels of psoriasis patients were significantly higher than those of controls. There was a positive correlation between PASI scores and serum uric acid levels of the patients. As hyperuricemia had a close relationship with psoriasis and PASI scores, we suggest monitoring patients with psoriasis for serum uric acid levels during treatment and follow-up.

    Full Text Available Few reports are available regarding the promoting factors that affect Helicobacter pylori (H. pylori infection in renal transplant (RTx patients. We report a cross-sectional study that was conducted on a group of stable RTx patients to investigate the relationship of various demographic and biochemical parameters of these patients with serum H. pylori IgG antibody titer as a sign of H. pylori infection. A total of 72 patients who were referred to the clinic for continuing their treatment were enrolled in this study. These patients included 47 males and 25 females. The mean age of the study patients was 44 (±12 years. The mean length of time after they received a transplanted kidney was 67.5 (±42 months (median: 62 months. The mean value of serum H. pylori-specific IgG antibody titer among these patients was 3 (±4.6 U/mL (median: 1 U/mL, and that of intact parathormone (iPTH was 18.4 (±8.2 pg/mL (median: 16.5 pg/mL. The mean serum magnesium (Mg was 1.9 (±0.20 mg/dL (median: 1.9 mg/dL and the mean creatinine clearance was 53 (±11 mL/min (median: 56 mL/min. In this study population, there was no significant difference in the H. pylori IgG antibody titers, serum iPTH, Mg, calcium, alkaline phosphatase and albumin levels as well as body mass index (BMI between males and females or diabetics and non-diabetics. There was no significant relationship between serum H. pylori IgG antibody titers and the age of the patients, BMI, serum Alb, phosphorus, Ca, serum leptin and serum ALP. Significant negative correlation between serum H. pylori IgG antibody titers and serum Mg (r = -0.30, P = 0.01 and serum iPTH (r = -0.25, P = 0.03 was seen. A significant positive correlation was found between serum H. pylori IgG antibody titer and creatinine clearance (r = 0.26, P = 0.02, and a near-significant positive correlation was found with the duration of RTx (r = 0.20, P = 0.08.

    Full Text Available Abstract Background The Finnish chiropractic profession is young and not fully accepted by Finnish healthcare authorities. The demographic profile and style of practice has not been described to date. However, as the profession seems to be under rapid development, it would be of interest to stakeholders, both chiropractic and political, to obtain a baseline description of this profession with a view to the development of future goals and strategies for the profession. The purpose of this study was to describe the chiropractic profession in Finland in relation to its demographic background, the demographics of their clinics, practice patterns, interactions with other health care practitioners and some of the professions' plans for the future. Methods A structured questionnaire survey was conducted in 2005, in which all 50 members of the Finnish Chiropractic Union were invited to participate. Results In all, 44 questionnaires were returned (response rate 88%. Eighty percent of the respondents were men, and 77% were aged 30 to 44 years old, most of whom graduated after 1990 with either a university-based bachelors' or masters' degree in chiropractic. Solo practice was their main practice pattern. The vast majority described their scope of practice to be based on a musculoskeletal approach, using the Diversified Technique, performing Soft Tissue Therapy and about two-thirds also used an Activator Instrument (mechanical adjusting instrument. The mean number of patient visits reported to have been seen weekly was 59 of which nine were new patients. Most practitioners found this number of patients satisfactory. At the initial consultation, 80% of respondents spent 30–45 minutes with their patients, 75% spent 20–30 minutes with "new old" patients and on subsequent visits 80% of respondents spent 15–30 minutes. Interactions with other health care professions were reasonably good and most of chiropractors intended to remain within the profession

    Suweis, Samir; Maritan, Amos; D'Odorico, Paolo

    2013-01-01

    Population growth is in general constrained by food production, which in turn depends on the access to water resources. At a country level, some populations use more water than they control because of their ability to import food and the virtual water required for its production. Here, we investigate the dependence of demographic growth on available water resources for exporting and importing nations. By quantifying the carrying capacity of nations based on calculations of the virtual water available through the food trade network, we point to the existence of a global water unbalance. We suggest that current export rates will not be maintained and consequently we question the long-run sustainability of the food trade system as a whole. Water rich regions are likely to soon reduce the amount of virtual water they export, thus leaving import-dependent regions without enough water to sustain their populations. We also investigate the potential impact of possible scenarios that might mitigate these effects throu...

  7. 3D face analysis for demographic biometrics

    2015-01-01

    Despite being increasingly easy to acquire, 3D data is rarely used for face-based biometrics applications beyond identification. Recent work in image-based demographic biometrics has enjoyed much success, but these approaches suffer from the well-known limitations of 2D representations, particularly variations in illumination, texture, and pose, as well as a fundamental inability to describe 3D shape. This paper shows that simple 3D shape features in a face-based coordinate system are capable of representing many biometric attributes without problem-specific models or specialized domain knowledge. The same feature vector achieves impressive results for problems as diverse as age estimation, gender classification, and race classification.

    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.

    To identify injuries that elderly sustain during high-energy trauma and determine which are associated with mortality. Retrospective review of prospectively collected database. Academic trauma center. Patients selected from database of all trauma admissions from January 2004 through June 2009. Study population consisted of patients directly admitted from scene of injury who sustained high-energy trauma with at least one orthopaedic injury and were 65 years or older (n = 597). Review of demographics, trauma markers, injuries, and disposition statuses. Statistical analysis using χ test, Student t test, and logistic regression analysis. The most common fractures were of the rib, distal radius, pelvic ring, facial bones, proximal humerus, clavicle, ankle, and sacrum. The injuries associated with the highest mortality rates were fractures of the cervical spine with neurological deficit (47%), at the C2 level (44%), and of the proximal femur (25%), pelvic ring (25%), clavicle (24%), and distal humerus (24%). The fractures significantly associated with mortality were fractures of the clavicle (P = 0.001), foot joints (P = 0.001), proximal humerus or shaft and head of the humerus (P = 0.002), sacroiliac joint (P = 0.004), and distal ulna (P = 0.002). Elderly patients present with significantly worse injuries, remain in the hospital longer, require greater use of resources after discharge, and die at 3 times the rate of the younger population. Although the high mortality rates associated with cervical spine, hip, and pelvic ring fractures were not unexpected, the injuries that were statistically associated with mortality were unexpected. Injuries such as clavicle fracture were statistically associated with mortality. As our population ages and becomes more active, the demographic may gain in clinical importance. Prognostic Level II.

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

    To determine the socio-demographic profiles and some clinical aspects of patients with rheumatoid arthritis (RA). Prospective, cross-sectional study. Ambulatory out- patient clinics of Kenyatta National Hospital (KNH), a public national and referral hospital. Out of 180 patients interviewed and examined, 60 met American College of Rheumatology (ACR) diagnostic criteria of RA. Of the 60 patients recruited 52 (87%) were females with male: female ratio of 1: 6.5. The mean age of patients was 41.38(+/- 16.8) years. There were two peaks of age of occurrence, 20-29 and 40-49 years. In 75% of the study patients, one or more of metacarpophalangeal joints of the hand were involved in the disease. Other frequently involved sites were--wrists, elbows, knees, ankles and glenohumeral joints of shoulders in a symmetrical manner. Serum rheumatoid factor was positive in 78.9% while rheumatoid nodules were present in 13.3% of the study patients. A large majority of patients (88%) had active disease with 18% having mild disease, 38% moderate activity and 32% having severe disease. Only 12% of patients had disease in remission. Forty six point seven per cent (46.7%) of the study patients were on at least one Disease Modifying anti Rheumatic Drugs (DMARD) from a selection of methotrexate, sulphasalazine, hydroxychloroquine and leflunamide. The most frequent drug combination was methotrexate plus prednisolone at 30% of the study population; while 66.7% were on oral prednisolone with 25% of the study patients taking only Non-Steroidal anti Inflammatory Drugs (NSAIDS). A large majority of ambulatory patients with RA had active disease. Most of them were sub-optimally treated, especially the use of DMARDS. About two thirds were on oral steroids. Sub-optimal therapy in relatively young patients, peak 20-29 and 40-49 years is likely to impact negatively on their disease control and quality of life.

    The demographic characteristics of the Arab region that present opportunities for population research are described, and existing obstacles to research are discussed. Additionally, the prospects for improving the situation are explored. The combination of high fertility, moderately low mortality, and in some instances massive new immigration have produced extremely rapid rates of population growth. During the early 1970s the population of the United Arab Emirates increased by an annual rate of at least 15%, Qatar's population by 8.5% annually, and Kuwait's population by 6% annually. Even the labor exporting countries had high rates of population growth. Thus the slowest growth between 1970 and 1975 occurred in Yemen, where the annual rate of population growth was 1.8%. Because of the large growth gap between birth and death rates in the Arab countries, the age composition is very young. Such young age composition reduces measures of fertility and mortality that do not control for age. It also means that rapid population growth will not cease in the near future. These are the major demographic characteristics of the region and some of the major opportunities for demographic research they present. Obstacles to research in the region include the absence of a tradition of census taking or survey research for demographic purposes and the absence of a registration system for vital statistics in many of the countries. According to informed sources, the governments involved are not always supportive of research per se. Political instability often works against conducting demographic research. Another obstacle to demographic research in the Arab Middle East is language. There is a shortage of qualified instructors to teach demography in universities working in Arabic. A promising development for population research is the increase of demographic data collection by the various governments. Also, non-Arab researchers and funding organizations have expressed growing interest

    Full Text Available Progression of Parkinson's disease (PD is highly variable, indicating that differences between slow and rapid progression forms could provide valuable information for improved early detection and management. Unfortunately, this represents a complex problem due to the heterogeneous nature of humans in regards to demographic characteristics, genetics, diet, environmental exposures and health behaviors. In this pilot study, we employed high resolution mass spectrometry-based metabolic profiling to investigate the metabolic signatures of slow versus rapidly progressing PD present in human serum. Archival serum samples from PD patients obtained within 3 years of disease onset were analyzed via dual chromatography-high resolution mass spectrometry, with data extraction by xMSanalyzer and used to predict rapid or slow motor progression of these patients during follow-up. Statistical analyses, such as false discovery rate analysis and partial least squares discriminant analysis, yielded a list of statistically significant metabolic features and further investigation revealed potential biomarkers. In particular, N8-acetyl spermidine was found to be significantly elevated in the rapid progressors compared to both control subjects and slow progressors. Our exploratory data indicate that a fast motor progression disease phenotype can be distinguished early in disease using high resolution mass spectrometry-based metabolic profiling and that altered polyamine metabolism may be a predictive marker of rapidly progressing PD.

    Hyponatremia is a frequent complication following subarachnoid hemorrhage (SAH), and is commonly attributed either to the syndrome of inappropriate antidiuretic hormone secretion (SIADH) or cerebral salt wasting syndrome (CSW). The object of this study is to elucidate the clinical demographics and sequelae of hyponatremia due to CSW in subjects with aneurysmal SAH. Retrospective chart review of patients >18 years with aneurysmal SAH admitted between January 2004 and July 2007 was performed. Subjects with moderate to severe hyponatremia (serum sodium <130 mmol l(-1)) were divided into groups consistent with CSW and SIADH based on urine output, fluid balance, natriuresis, and response to saline infusion. Clinical demographics were compared. Of 316 subjects identified, hyponatremia (serum sodium <135 mmol l(-1)) was detected in 187 (59.2%) subjects and moderate to severe hyponatremia in 48 (15.2%). Of the latter group, 35.4% were categorized with SIADH and 22.9% with CSW. Compared to eunatremic subjects, hyponatremia was associated with significantly longer hospital stay (15.7 +/- 1.9 vs. 9.6 +/- 1.1 days, p < 0.001). Subjects with CSW had similar mortality and duration of hospital stay vs. those with SIADH. Though less common than SIADH, CSW was detected in approximately 23% of patients with history of aneurysmal SAH and was not clearly associated with enhanced morbidity and mortality compared to subjects with SIADH. Further studies regarding the pathogenesis and management, along with the medical consequences, of CSW are important.

  15. Impact of demographic policy on population growth.

    Various bourgeois theories, including the reactionary Malthusianism and its variants, challenge the Marxist-Leninist revolutionary theory on the growth of population. Bourgeois science maintains that unchanging biological laws of proliferation form the foundation of social life. Malthus, in his "An Essay on the Principle of Population," contends that population increases in a geometric rate, while means of subsistence tend to increase only in an arithmetic rate: neither the way of production nor social conditions but this law of nature in control of proliferation had been the cause of overpopulation, which again leads to misery, hunger, and unemployment. From this follows the possible conclusion that the working classes should be concerned not about how to change the social order but how to reduce the number of childbirths. Progressive science views the laws of social life in a totally different way. Marxism-Leninism teaches that population size, despite the markedly important role played by it in historical progress, fails to represent that main force of social progress which determines the mode of production and of the distribution of material goods, but just the reverse: the mode of production determines the growth of population, the changes in its density and composition. Marxism-Leninism teaches that each historical stage of production (slavery, feudalism, capitalism) has its own special, historically valid demographic law. Bourgeois science maintains that humankind faces an absolute overpopulation caused by the means of production lagging behind the growth of population. Actually this is only a relative overpopulation due to the fact that capitalistic production is subjected to the interests of increasing capitalistic profit and not to those of meeting the demands of population. In socialist countries, production is incessantly developing and expanding, and employment of the entire productive population is ensured. Consequently, the problem of relative

    Introduction The quantification of parasite movements can provide valuable information for control strategy planning across all transmission intensities. Mobile parasite carrying individuals can instigate transmission in receptive areas, spread drug resistant strains and reduce the effectiveness of control strategies. The identification of mobile demographic groups, their routes of travel and how these movements connect differing transmission zones, potentially enables limited resources for interventions to be efficiently targeted over space, time and populations. Methods National population censuses and household surveys provide individual-level migration, travel, and other data relevant for understanding malaria movement patterns. Together with existing spatially referenced malaria data and mathematical models, network analysis techniques were used to quantify the demographics of human and malaria movement patterns in Kenya, Uganda and Tanzania. Movement networks were developed based on connectivity and magnitudes of flow within each country and compared to assess relative differences between regions and demographic groups. Additional malaria-relevant characteristics, such as short-term travel and bed net use, were also examined. Results Patterns of human and malaria movements varied between demographic groups, within country regions and between countries. Migration rates were highest in 20–30 year olds in all three countries, but when accounting for malaria prevalence, movements in the 10–20 year age group became more important. Different age and sex groups also exhibited substantial variations in terms of the most likely sources, sinks and routes of migration and malaria movement, as well as risk factors for infection, such as short-term travel and bed net use. Conclusion Census and survey data, together with spatially referenced malaria data, GIS and network analysis tools, can be valuable for identifying, mapping and quantifying regional connectivities

    The Anniston Community Health Survey was a community-based cross-sectional study of Anniston, Alabama, residents who live in close proximity to a former PCB production facility to identify factors associated with serum PCB levels. The survey comprises 765 Anniston residents who completed a questionnaire interview and provided a blood sample for analysis in 2005–2007. Several reports based on data from the Anniston survey have been previously published, including associations between PCB exposure and diabetes and blood pressure. In this study we examine demographic, behavioral, dietary, and occupational characteristics of Anniston survey participants as predictors of serum PCB concentrations. Of the 765 participants, 54% were White and 45% were African-American; the sample was predominantly female (70%), with a mean age of 55 years. Serum PCB concentrations varied widely between participants (range for sum of 35 PCBs: 0.11–170.4 ng/g wet weight). Linear regression models with stepwise selection were employed to examine factors associated with serum PCBs. Statistically significant positive associations were observed between serum PCB concentrations and age, race, residential variables, current smoking, and local fish consumption, as was a negative association with education level. Age and race were the most influential predictors of serum PCB levels. A small age by sex interaction was noted, indicating that the increase in PCB levels with age was steeper for women than for men. Significant interaction terms indicated that the associations between PCB levels and having ever eaten locally raised livestock and local clay were much stronger among African-Americans than among White participants. In summary, demographic variables and past consumption of locally produced foods were found to be the most important predictors of PCB concentrations in residents living in the vicinity of a former PCB manufacturing facility.

    Wildfires are an important component of terrestrial ecosystem ecology but also a major natural hazard to societies, and their frequency and spatial distribution must be better understood. At a given location, risk from wildfire is associated with the annual fraction of burned area, which is expected to increase in response to climate warming. Until recently, however, only a few global studies of future fire have considered the effects of other important global environmental change factors such as atmospheric CO2 levels and human activities, and how these influence fires in different regions. Here, we contrast the impact of climate change and increasing atmospheric CO2 content on burned area with that of demographic dynamics, using ensembles of climate simulations combined with historical and projected population changes under different socio-economic development pathways for 1901-2100. Historically, humans notably suppressed wildfires. For future scenarios, global burned area will continue to decline under a moderate emissions scenario, except for low population growth and fast urbanization, but start to increase again from around mid-century under high greenhouse gas emissions. Contrary to common perception, we find that human exposure to wildfires increases in the future mainly owing to projected population growth in areas with frequent wildfires, rather than by a general increase in burned area.

  3. Demographic impact of vaccination: a review.

    Vaccination is one of the most powerful means to save lives and to increase the level of health of mankind. However, the impact of immunization against the most threatening infectious agents on life expectancy has been the object of a still open debate. The main issues are: the relative influence of nutrition and infectious diseases on demographic patterns of populations; the possibility that lives saved thanks to vaccination are subsequently lost due to other competing causes of death; the positive indirect effect of immunization on other causes of death. With regard to past evidence, several data from the United Kingdom and Scandinavian countries show that the widespread use of smallpox vaccination starting at the beginning of the nineteenth century resulted in a marked and sustained decline not only of smallpox-related deaths, but also of the overall crude death rate, and contributed greatly to an unprecedented growth of European population. As to the present, it is estimated that 3 million children are saved annually by vaccination, but 2 million still die because they are not immunized. Tetanus, measles and pertussis are the main vaccine-preventable killers in the first years of life. Data from Bangladesh show that full implementation of EPI vaccines has the potential of reducing mortality by almost one half in children aged 1-4 years. Recent progress in the development of vaccines against agents responsible for much mortality in the developing countries make it possible to forecast a further substantial reduction of deaths for infectious diseases in the next century.

  4. The shifting demographic landscape of pandemic influenza.

    Full Text Available As Pandemic (H1N1 2009 influenza spreads around the globe, it strikes school-age children more often than adults. Although there is some evidence of pre-existing immunity among older adults, this alone may not explain the significant gap in age-specific infection rates.Based on a retrospective analysis of pandemic strains of influenza from the last century, we show that school-age children typically experience the highest attack rates in primarily naive populations, with the burden shifting to adults during the subsequent season. Using a parsimonious network-based mathematical model which incorporates the changing distribution of contacts in the susceptible population, we demonstrate that new pandemic strains of influenza are expected to shift the epidemiological landscape in exactly this way.Our analysis provides a simple demographic explanation for the age bias observed for H1N1/09 attack rates, and suggests that this bias may shift in coming months. These results have significant implications for the allocation of public health resources for H1N1/09 and future influenza pandemics.

    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.

  7. Demographic evidence for adaptive theories of aging.

    Pleiotropic theories for the evolutionary origins of senescence have been ascendant for forty years (see, for example, G. Williams (1957) Evolution, 11, 398-411; T. Kirkwood (1977) Nature, 270, 301-304), and it is not surprising that interpreters of demographic data seek to frame their results in this context. But some of that evidence finds a much more natural explanation in terms of adaptive aging. Here we re-interpret the 1997 results of the Centenarian Study in Boston, which found in their sample of centenarian women an excess of late childbearing. The finding was originally interpreted as a selection effect: a metabolic link between late menopause and longevity. But we demonstrate that this interpretation is statistically strained, and that the data in fact indicate a causal link: bearing a child late in life induces a metabolic response that promotes longevity. This conclusion directly contradicts some pleiotropic theories of aging that postulate a "cost of reproduction", and it supports theories of aging as an adaptive genetic program.

    Sex, age and sexual maturation are key biological parameters for aspects of life history and are fundamental information for assessing demographic changes and the reproductive viability and performance of natural populations under exploitation pressures or in response to environmental influences. Much of the information available on the reproductive condition, length at sexual maturity and sex determinations of endangered species has been derived from direct examination of the gonads in dead animals, either intentionally or incidentally caught, or from stranded individuals. However, morphological data, when used alone, do not provide accurate demographic information in sexually monomorphic marine vertebrate species (e.g. sharks, sea turtles, seabirds and cetaceans). Hormone determination is an accurate and non-destructive method that provides indirect information about sex, reproductive condition and sexual maturity of free-ranging individuals. Correlations between sex steroid concentrations and biochemical parameters, gonadal development and state, reproductive behaviour and secondary external features have been already demonstrated in many species. Different non-lethal approaches (e.g. surgical and mark-recapture procedures), with intrinsic advantages and disadvantages when applied on free-ranging organisms, have been proposed to asses sex, growth and reproductive condition. Hormone determination from blood samples will generate valuable additional demographic information needed for stock assessment and biological conservation.

    Objective To be released specifically after myocardial damage. The goal of this study was to measure serum cardiac troponin I levels after open heart surgery in children, and to evaluate relevance between TnTi and perioperative multi-factors. Methods Fifty-seven consecutive pediatric patients undergoing elective correction of congenital heart diseases were divided into group A (TOF, n=31) and group B (VSD, n=26). Blood samples were drawn preoperatively, 5min(T0), 6h(T6), 12h(T12), 24h(T24), 48h(T48), 72h(T72) after removal of aortic cross clamping. Myocardial protection consisted of moderate systemic hypothermia (30℃~ 32℃), cold crystalloid cardioplegia and topical cooling. Demographic information, cardiac defect, repair procedure, duration of bypass (CPBT), cross-clamping time (CCT), clinical score for cardiac function, electrocardiographic changes and outcomes were recorded. Results Compared with the baseline value, serum concentration of troponin I peaked at T0 (P0.05). Peak CTnI was 118 and 55 times higher than the baseline value, respectively in group A and group B.There was a positive correlation between peak CTnI and CPBT, CCT (r=0.51; P<0.01), myocardial operative injury after ventriculotomy and muscle resection (r=0.35, P<0.01). Also the peak CTnI value was correlated to the clinical score for cardiac function (r=-0.52; P<0.01). 2.3μg/L was a cutoff value which was highly predictive for postoperative recovery and inotropic support.Conclusion Postoperative serum troponin I is a highly specific and sensitive marker for myocardial ischemia and injury; therefore, its measurement may contribute to the assessment of recovery and outcome after open heart surgery.

    This study sought to further evaluate the possible effects of serum calcium level on prostate cancer (PC) risk, with considering the age, body mass index (BMI), and sex steroid hormones. Using data from a prospective multicenter study, serum calcium concentration, as well as thorough demographic and medical characteristics, were determined in 194 cases with newly diagnosed, clinicopathologically confirmed PC and 317 controls, without any malignant disease, admitted to the same network of hospitals. Serum total and ionized calcium levels were categorized into tertiles. Multivariate logistic regression model was used to estimate odds ratios (OR) and corresponding 95% confidence intervals (CI) after adjustment for major potential confounders, including age, BMI, smoking, alcohol, education, occupation, marital status, family history of PC, and sex hormones level. The mean serum calcium level (±SD) in case and control groups was 9.22 (±0.46) mg/dl and 9.48 (±0.51) mg/dl, respectively (P < 0.001). After adjustment for mentioned confounders, a significant trend of decreasing risk was found for serum total calcium concentration (OR = 0.27, 95% CI = 0.12-0.59, comparing the highest with the lowest tertile) and ionized calcium (OR = 0.25, 95% CI = 0.10-0.58). An increase of 1 mg/dl in serum calcium level was associated with a significant decrease in PC risk (OR = 0.52; 95% CI = 0.34-0.76). Our findings reveal the inverse association between serum total and ionized concentrations and PC risk, which supports the hypothesis that calcium may protect against PC. Furthermore, no evidence was found regarding age, BMI, and sex steroid hormones to modify the association between serum calcium and PC risk.

    Full Text Available An important aspect is social learning involves acquisition of knowledge, skills, abilities, habits over from friends, colleagues, social group they belong to.Purpose and research hypothesisSmall school activities is more effective if concrete terms of reference that would bring back to memory certain knowledge that to suggest solutions to solve and give him the opportunity to correct by comparing statements reality, this is why the main method of conducting educational process is observation.Working methodResearch group consisted of children of school age (7-12 years. Demographic information about the subjects covered: health, family composition and housing.Research resultsThe vast majority of children had good health, with no differences between the control group and the experimental group (p = 0.428. Regarding housing conditions, over half (57.1% in the control group and 51.4% in control group live in two rooms, no child lives in a studio and two children in the experimental group live at home with yard. In both groups, two children did not provide information regarding their housing situation. Of children included in the study, a very high percentage (82.9% in the control group and 68.6% in the experimental group is single copies: only six children in the control group and 10 in the control group have brothers or sisters. Under these conditions, more than half of the children have their own room (65.7% in the control group and 57.1% in the experimental group, the rest sharing a room with a brother or sister, or parents (in the case of two children experimental group.ConclusionsWe conclude that in terms of demographic variables (health status, family composition, housing, there are no differences between children in the two groups. Optimal integration in a social environment is based not only on the correct development of intellectual faculties, namely, the possibility of natural evolution on the moral values, scientific and so on, but

    Full Text Available Continuing improvements in analytical technology along with an increased interest in performing comprehensive, quantitative metabolic profiling, is leading to increased interest pressures within the metabolomics community to develop centralized metabolite reference resources for certain clinically important biofluids, such as cerebrospinal fluid, urine and blood. As part of an ongoing effort to systematically characterize the human metabolome through the Human Metabolome Project, we have undertaken the task of characterizing the human serum metabolome. In doing so, we have combined targeted and non-targeted NMR, GC-MS and LC-MS methods with computer-aided literature mining to identify and quantify a comprehensive, if not absolutely complete, set of metabolites commonly detected and quantified (with today's technology in the human serum metabolome. Our use of multiple metabolomics platforms and technologies allowed us to substantially enhance the level of metabolome coverage while critically assessing the relative strengths and weaknesses of these platforms or technologies. Tables containing the complete set of 4229 confirmed and highly probable human serum compounds, their concentrations, related literature references and links to their known disease associations are freely available at http://www.serummetabolome.ca.

    Whale sharks Rhincodon typus are globally threatened, but a lack of biological and demographic information hampers an accurate assessment of their vulnerability to further decline or capacity to recover. We used laser photogrammetry at two aggregation sites to obtain more accurate size estimates of free-swimming whale sharks compared to visual estimates, allowing improved estimates of biological parameters. Individual whale sharks ranged from 432–917 cm total length (TL) (mean ± SD = 673 ± 118.8 cm, N = 122) in southern Mozambique and from 420–990 cm TL (mean ± SD = 641 ± 133 cm, N = 46) in Tanzania. By combining measurements of stranded individuals with photogrammetry measurements of free-swimming sharks, we calculated length at 50% maturity for males in Mozambique at 916 cm TL. Repeat measurements of individual whale sharks measured over periods from 347–1,068 days yielded implausible growth rates, suggesting that the growth increment over this period was not large enough to be detected using laser photogrammetry, and that the method is best applied to estimating growth rates over longer (decadal) time periods. The sex ratio of both populations was biased towards males (74% in Mozambique, 89% in Tanzania), the majority of which were immature (98% in Mozambique, 94% in Tanzania). The population structure for these two aggregations was similar to most other documented whale shark aggregations around the world. Information on small (<400 cm) whale sharks, mature individuals, and females in this region is lacking, but necessary to inform conservation initiatives for this globally threatened species.

    Full Text Available Side by side with tumultuous social processes in the end of XXth century great demographical changes have been taking place in Serbia, such as: the decline of nuptiality and fertility, postponement of family formation into older ages of life course of individuals, the rise of: extramarital births as well as adolescent pregnancies and live births, the spread of one-parent households, particularly of lone mothers, and divorces. Besides that, the main feature of the demographic development of Serbia has been increased mobility of population, namely migrations of highly educated professionals to the West ("brain drain" and forced migration of refugees and internally displaced persons to Serbia, as a consequence of armed conflicts in its surroundings and at Kosovo and Metohija. All the above-mentioned demographical changes caused the precomposition of households, as profound associations of population, where its biological and socio-economical reproductions take place. The information of last census of population of Serbia in 2002 indicate that according to the features of family and households, Serbia has approached the countries of Central and Eastern Europe, that are forerunning in the process of post-socialistic transformation and European integrations. Common characteristics of all those countries are: decrease of universality and popularity of marriage delay of childbearing, continuation of earlier demographic tendencies: of low natality, depopulation and aging of population. All those processes have contributed to the transformation of prevailing forms of households, i.e. decline of nuclear family units and the rise of single person households households of aged persons, as well as single-parent ones. As to the Serbia the demographic differences between its separate parts: Vojvodina and central Serbia, have been fading for the first time in its history, owing to previous socio-demographic developments starting from the beginning of XXth

    Full Text Available Abstract Background The Approximate Bayesian Computation (ABC approach has been used to infer demographic parameters for numerous species, including humans. However, most applications of ABC still use limited amounts of data, from a small number of loci, compared to the large amount of genome-wide population-genetic data which have become available in the last few years. Results We evaluated the performance of the ABC approach for three 'population divergence' models - similar to the 'isolation with migration' model - when the data consists of several hundred thousand SNPs typed for multiple individuals by simulating data from known demographic models. The ABC approach was used to infer demographic parameters of interest and we compared the inferred values to the true parameter values that was used to generate hypothetical "observed" data. For all three case models, the ABC approach inferred most demographic parameters quite well with narrow credible intervals, for example, population divergence times and past population sizes, but some parameters were more difficult to infer, such as population sizes at present and migration rates. We compared the ability of different summary statistics to infer demographic parameters, including haplotype and LD based statistics, and found that the accuracy of the parameter estimates can be improved by combining summary statistics that capture different parts of information in the data. Furthermore, our results suggest that poor choices of prior distributions can in some circumstances be detected using ABC. Finally, increasing the amount of data beyond some hundred loci will substantially improve the accuracy of many parameter estimates using ABC. Conclusions We conclude that the ABC approach can accommodate realistic genome-wide population genetic data, which may be difficult to analyze with full likelihood approaches, and that the ABC can provide accurate and precise inference of demographic parameters from

    Full Text Available Background: Effective tourism management in the field of sports tourism requires an understanding of differences in socioeconomic characteristics both within and between different market segments. Objective: In the broad tourism market demographic characteristics have been extensively analyzed for differences in destination choices, however little is known about demographic factors affecting sport tourists' decisions. Methods: A sample of Slovenian sports tourists was analyzed using data from a comprehensive survey of local and outbound tourist activity conducted by the Statistical Office of the Republic of Slovenia in 2008. After data weighting the information for 353,783 sports related trips were available for analysis. The research model adopted suggests that four socio-demographic characteristics (gender, age, level of education and income significantly affect a tourist's choice of sports related travel either locally within Slovenia or to a foreign country. Furthermore the destination (local or foreign has an influence on the choice of the type of accommodation selected and the tourist's total expenditure for the trip. For testing the first part of our model (the socio-demographic characteristics effects a linear regression was used, and for the final part of the model (the selection of accommodation type and travel expenditure t-test were applied. Results: The result shows the standardized β regression coefficients are all statistically significant at the .001 level for the tested socio-demographic characteristics and also the overall regression model was statistically significant at .001 level. Conclusions: With these results the study confirmed that all the selected socio-demographic characteristics have a significant influence on the sport-active tourist when choosing between a domestic and foreign tourism destination which in turn affect the type of accommodation chosen and the level of expenditure while travelling.

    Full Text Available Orientation: The focus of this study was to investigate the relationship between socio-demographic characteristics and the work–home interaction in different occupational groups in South Africa.Research purpose: The main research aim of the study was to investigate the socio-demographic predictors of negative and positive work–home interaction of South African employees.Motivation for the study: Little information is known about the prevalence of work–home interaction within groups. This study is aimed at enabling the researcher and organisations to identify those groups that are at risk of negative interference and which are prone to positive interaction, to allow for the development of appropriate strategies and intervention programmes.Research design, approach and method: A cross-sectional survey design was used in the study. A sample (N = 2040 was taken from four South African industries (i.e. the police service, the earthmoving equipment industry, mining and nursing. A socio-demographic questionnaire and the Survey Work–Home Interaction-Nijmegen (SWING were used.Main findings: The results indicated that robust predictors included occupation, gender and language for negative work–home interference; occupation, age and language for positive work–home interference; occupation and language for negative home–work interference; and occupation, age, education and language for positive home–work interference.Practical/managerial implications: The implications of the study are that negative and positive work–home interaction is uniquely associated with socio-demographic characteristics. Work–life balance initiatives should, therefore, be carefully tailored to address the needs of each socio-demographic group.Contribution/value-add: The findings of the study suggest answers to the management of the work–home interaction among various socio-demographic groups in organisations.

    Fertility and life expectancy have changed since the breakup of the Soviet republics in 1991 and continue to change very rapidly. Before 1991, the USSR was the fastest growing developed country in the world. Annual growth rates in the mid-1980s were 0.9% compared to only 0.1% in Europe or 1.1% in the US. Immigration did not greatly affect the USSR's growth rate. By 1993, the population had declined in 8 of the 15 former republics. Deaths exceeded births in Russia, Belarus, Ukraine, Estonia, and Latvia, followed by Lithuania in 1994. The last census was conducted in 1989. Fertility declined in Russia from 1.9 in 1990 to 1.4 in 1993. Fertility has been low in Lithuania at 1.7, in the Ukraine at 1.6, in Latvia at 1.5, and in Estonia at 1.4. Kazakhstan, Georgia, and Kyrgyzstan have experienced fertility decline, which was affected by emigration to Russia and other countries after 1990. 25 million Russians have resided in the former republics in 1990. In Kazakhstan, the 160,000 more births than deaths were offset by 200,000 emigrants. Central republics with higher fertility experienced declines after 1990; for example, Kyrgyzstan declined from 3.7 in 1990 to 3.3 in 1993. Life expectancy for males in Russia in 1993 was 58.9 years, which was a decline from 63.8 years in 1990. About 50% of the decline in life expectancy was due to circulatory diseases, and about 25% was due to external causes such as accidents, suicide, and alcoholism. Infant mortality has been increasing since 1990; for example, it increased in the Ukraine from 12.9 in 1990 to 14.1 in 1992. Russia's population in 1993 experienced 700,000 more deaths than births. The demographic impact will be declining school enrollments and smaller employment among the working population to support the aged. The change to a market economy has been uneven in Russia, where it has advanced more rapidly than in the republics. It is unclear whether the declining birth rate and increasing mortality rates will continue, but

    Helicobacter pylori infection can cause disease from mild to severe that may be accompanied by micronutrient deficiencies. We aimed to investigate serum zinc, copper, magnesium and selenium levels in Helicobacter pylori positive children. Thirty-four children, with chronic abdominal pain and diag-nosed to be Helicobacter pylori-positive and 20 healthy children with the same demo-graphic characteristics were included in the study. Serum zinc, copper and magnesium levels were measured in the flame unit of atomic absorption spectrophotometer, selenium levels were measured in the graphite unit of the same atomic absorption spectrophotometer. Serum zinc levels were significantly higher and serum magnesium levels were significantly lower (p0.05). There was no significant difference between serum selenium levels of two groups. We concluded that in Helicobacter pylori-positive children, many trace elements and mineral metabolism may change.

  16. Study identifies socio-cultural factors affecting demographic behaviour.

    1994-01-01

    The United Nations Educational, Scientific, and Cultural Organization (UNESCO) is undertaking a project that will produce a state-of-the-art paper on sociocultural factors affecting demographic behavior. Particular emphasis will be placed on reproductive behavior in Africa, Asia, Latin America, and the Arab states region. The extent to which this information is incorporated in current population policies and programs will also be examined, and recommendations will be made. The factors to be studied include family and kinship structure; gender status and role; patterns of sexual relations and procreation in general and adolescent sexual behavior and fertility; religion, beliefs, customs, and traditions concerned with sexual relations and procreation; child rearing, socialization, and education; status and role of women; and sociocultural change, change agents, and influentials. The literature search will provide an inventory of methodologies. Guidelines on the use of the methodologies will be drafted for use by project personnel. These will later be tested in pilot studies in rural and urban communities in selected developing countries. The goal is to design programs that will accelerate contraceptive acceptance and sustain contraceptive practice by being sensitive to the sociocultural influences on the reproductive behavior of different subpopulations.

    Full Text Available BACKGROUND Pregnancy though is a physiological event in a woman’s life, it has its own associated complications. In teenage pregnancies, the physical and emotional state of stress coupled with biological immaturity leads to adverse effect both on the health of the mother and the foetus. METHODS This study is a clinical prospective study analysing the demographics, maternal health issues and the foetal outcome in teenage pregnancies. The study was conducted over a period of one year at a government tertiary care center. Pregnant women in the age group of 13-19 years who delivered during the study period were included in the study group. All pregnant women over 20 years of age who delivered during the same period were taken as control group. Women who had medical disorders complicating pregnancy were excluded from the study. Anaemia, pregnancy induced hypertension, antepartum haemorrhage and mode of delivery were the maternal outcomes that were noted. Intrauterine growth retardation, prematurity, low birth weight, APGAR score were analysed with respect to the foetus. RESULTS In this study, the total number of pregnant women who delivered during the study period were 4782, 536 were teenage mothers, constituting 11.2% of the total pregnancies. Of the 536 teenage mothers, 69.78% belonged to the rural areas and 71.64% were found to have inadequate antenatal visits to the hospital. The mean age of teenage pregnancy was 17.18 years. Incidence of anaemia was 44.2% in comparison, the control group had an incidence of 33.02%. In our study, incidence of Pregnancy induced hypertension was 18.64% in teenage mothers and 10.6% in non-teenage mothers. The incidence of Antepartum Haemorrhage in our study was 8.94% in teenage mothers. Incidence of lower segment caesarean section was 22.76% in the teenage group as compared to 14.57% in the non-teenage group. In our study, 13.05% of teenage mothers had preterm deliveries as compared to 6.40% of non-teenage mothers

    Members of the Education & Workforce Working Group and the American Institute of Physics (AIP) conducted the first ever National Demographic Survey of working professionals for the 2012 National Academy of Sciences Solar and Space Physics Decadal Survey to learn about the demographics of this sub-field of space science. The instrument contained questions for participants on: the type of workplace; basic demographic information regarding gender and minority status, educational pathways (discipline of undergrad degree, field of their PhD), how their undergraduate and graduate student researchers are funded, participation in NSF and NASA funded spaceflight missions and suborbital programs, and barriers to career advancement. Using contact data bases from AGU, the American Astronomical Society's Solar Physics Division (AAS-SPD), attendees of NOAA's Space Weather Week and proposal submissions to NSF's Atmospheric, Geospace Science Division, the AIP's Statistical Research Center cross correlated and culled these data bases resulting in 2776 unique email addresses of US based working professionals. The survey received 1305 responses (51%) and generated 125 pages of single space answers to a number of open-ended questions. This talk will summarize the highlights of this first-ever demographic survey including findings extracted from the open-ended responses regarding barriers to career advancement which showed significant gender differences.

    Urticaria is a common cause for consultation in general and specialised medical practices. There is scarce information on the characteristics of patients suffering acute urticaria in Latin America. To investigate demographic and clinical features of patients with acute urticaria attending two allergy clinics in Caracas, Venezuela. A prospective study of all new patients who consulted during a three-year period because of acute urticaria. Information on age, gender, symptom duration, previous medical history, body distribution of wheals and angio-oedema, laboratory investigations, skin prick tests, and pharmacological treatment, was collected. Patients were classified according to their age as children/adolescents and adults. Two hundred and forty eight patients (177 adults and 71 children) were studied. Acute urticaria was more frequent in middle-aged atopic female patients. Lesions more often involved upper and lower limbs and head, and 31% of patients exhibited generalised urticaria. Laboratory investigations, performed only in selected cases, did not contribute to the final diagnosis. Most frequent subtypes of acute urticaria were spontaneous, dermographic, papular, and drug-induced urticaria. Most patients were treated with non-sedating antihistamines, with increased use of cetirizine and levocetirizine in children, while 5.6% of children and 20.3% of adults required the addition of short courses of systemic corticosteroids. Acute urticaria is a frequent cause of consultation for allergists, affecting more often middle-aged female atopic patients. The use of extensive complementary tests does not seem to be cost-effective for this clinical condition. Spontaneous, dermographic, papular and drug-induced urticaria are the most common subtypes.

  6. Spatial extent in demographic research - approach and problems

    Directory of Open Access Journals (Sweden)

    Knežević Aleksandar

    2015-01-01

    Full Text Available One of the starting methodological problems in demographic research is the definition of spatial extent, which mostly doesn’t correspond to spatial extent already defined by different levels of administrative-territorial unitsthat are used for distribution of usable statistical data. That’s why determining the spatial extent of a demographic research is closely tied with administrative-territorial division of the territory that is being researched, wherein the fact that differentiation of demographic phenomena and processes cannot be the only basis of setting the principles of regionalization must be strictly acknowledged. This problem is particularly common in historical demographic analyses of geographically determined wholes, which are in administratively-territorial sense represented by one or more smaller territorial units, with their borders changing through the history, which directly affects comparability of the statistical data, and makes it considerably more difficult to track demographic change through longer time intervals. The result of these efforts is usually a solution based on a compromise which enables us to examine the dynamics of population change with little deviation from already defined borders of regional geographic wholes. For that reason in this paper the problem of defining spatial extent in demographic research is examined trough several different approaches in case of Eastern Serbia, as a geographically determined region, a historic area, a spatially functioning whole and as a statistical unit for demographic research, with no judgment calls in regard to any of the regionalization principles.

    2014-02-01

    Full Text Available Background: Demographic information is foundational for the planning and management of social programmes, in particular health services. The existing INDEPTH network surveillance sites are limited to coverage of sedentary populations. Including mobile populations in this approach would be expensive, time consuming and possibly low in accuracy. Very little is known about the demography of mobile pastoralists and their animals, so innovative approaches are urgently needed. Objective: To test and evaluate a mobile demographic surveillance system for mobile pastoralist households, including livestock herds, using mobile phones. Design: Mobile pastoralist camps were monitored (10 for 12 months and 10 for 18 months using biweekly mobile phone calls with camp leaders and their wives to conduct interviews about the households and livestock. The collected information was validated through personal visits, GPS data and a livestock demographic model. Results: The study showed the feasibility of mobile phone surveillance for mobile pastoralist camps, providing usable, valid information on human and livestock population structures, pregnancy outcomes and herd dynamics, as well as migration patterns. The approach was low-cost and applicable with the existing local resources. Conclusion: Demographic surveillance in mobile populations is feasible using mobile phones. Expansion of the small-scale system into a full mobile demographic surveillance system is warranted and would likely lead to improved planning and provision of human and animal health care.

    reversal in the trend of the total population of Serbia came as a surprise or much earlier than expected for the forecasters. The probabilistic population forecast of Serbia provides results that users can clearly understand and use along with attached information on error magnitude. Before running the projection model, it was necessary to adjust the 2012 UN estimates for Serbia to suit the current official estimates and recent relevant studies on demographic trends in the country. The comparison of probabilistic hypotheses and results with the current official projection aims to highlight the key benefits of the new approach in terms of reduced subjectivity, improved accuracy and quantified uncertainty. The latter could be particularly relevant for decision makers allowing them to calculate the expected costs involved in wrong decisions. From the perspective of the forecast based on "UN model", the strong optimism of the current official projection appears to be groundless. Besides, the empiric evaluation of the probabilistic distributions of total population suggests that it fully reflects the pattern of observed uncertainty in the past forecasts of Serbian population.

  10. Interpreting serum risperidone concentrations.

    2005-02-01

    Risperidone is an atypical antipsychotic commonly used for treatment of schizophrenia and other psychotic disorders. Although therapeutic drug monitoring is not routine for any of the atypical antipsychotics, serum antipsychotic concentrations are measured routinely to assess treatment nonadherence. In humans, risperidone is metabolized by cytochrome P450 2D6 to 9-hydroxyrisperidone; together these constitute the active moiety. Dose-proportional increases in serum concentrations have not been reported for the parent drug, but have been reported for 9-hydroxyrisperidone and the active moiety (i.e., the combined concentrations of risperidone and 9-hydroxyrisperidone). We describe a 34-year-old Caucasian man of Sicilian descent with a history of schizophrenia, disorganized type. He was suspected to be noncompliant with his risperidone therapy. Initially, active moiety risperidone concentrations increased linearly with prescribed dosage increases. However, with continued increases, active moiety concentrations adjusted downward and remained 17-36% below anticipated levels. We propose a method for estimating target active moiety concentrations of risperidone based on dosage-a method that may be used to guide clinicians in assessing nonadherence to risperidone treatment.

    Full Text Available Deficiencies in essential trace elements are associated with impaired immunity in tuberculosis infection. However, the trace element concentrations in the serum of Korean patients with tuberculosis have not yet been investigated. This study aimed to compare the serum trace element concentrations of Korean adult patients with tuberculosis with noninfected controls and to assess the impact of serum trace element concentration on clinical outcome after antituberculosis treatment. The serum concentrations of four trace elements in 141 consecutively recruited patients with tuberculosis and 79 controls were analyzed by inductively coupled plasma-mass spectrometry. Demographic characteristics were also analyzed. Serum cobalt and copper concentrations were significantly higher in patients with tuberculosis compared with controls, while zinc and selenium concentrations were significantly lower (p < 0.01. Moreover, serum selenium and zinc concentrations were positively correlated (ρ = 0.41, p < 0.05. A high serum copper concentration was associated with a worse clinical outcome, as assessed after one month of antituberculosis therapy. Specifically, culture-positive patients had higher serum copper concentrations than culture-negative patients (p < 0.05. Patients with tuberculosis had altered serum trace element concentrations. Further research is needed to elucidate the roles of individual trace elements and to determine their clinical impact on patients with tuberculosis.

    A higher serum phosphorus level is associated with cardiovascular disease (CVD) events among community-living populations. Mechanisms are unknown. The ankle-brachial index (ABI) provides information on both atherosclerosis and arterial stiffness. In this cross-sectional study (2000-2002), the authors evaluated the association of serum phosphorus levels with low ( or =1.40 or incompressible) ABI as compared with intermediate ABI in 5,330 older US men, among whom the mean serum phosphorus level was 3.2 mg/dL (standard deviation, 0.4), 6% had a low ABI, and 5% had a high ABI. Each 1-mg/dL increase in serum phosphorus level was associated with a 1.6-fold greater prevalence of low ABI (95% confidence interval (CI): 1.2, 2.1; P < 0.001) and a 1.4-fold greater prevalence of high ABI (95% CI: 1.0, 1.9; P = 0.03) in models adjusted for demographic factors, traditional CVD risk factors, and kidney function. However, the association of phosphorus with high ABI differed by chronic kidney disease (CKD) status (in persons with CKD, prevalence ratio = 2.96, 95% CI: 1.61, 5.45; in persons without CKD, prevalence ratio = 1.14, 95% CI: 0.81, 1.61; interaction P = 0.04). In conclusion, among community-living older men, higher phosphorus levels are associated with low ABI and are also associated with high ABI in persons with CKD. These associations may explain the link between serum phosphorus levels and CVD events.

    2016-01-01

    Background An increasing number of patients from diverse demographic groups share and search for health-related information on Web-based social media. However, little is known about the content of the posted information with respect to the users’ demographics. Objective The aims of this study were to analyze the content of Web-based health-related social media based on users’ demographics to identify which health topics are discussed in which social media by which demographic groups and to help guide educational and research activities. Methods We analyze 3 different types of health-related social media: (1) general Web-based social networks Twitter and Google+; (2) drug review websites; and (3) health Web forums, with a total of about 6 million users and 20 million posts. We analyzed the content of these posts based on the demographic group of their authors, in terms of sentiment and emotion, top distinctive terms, and top medical concepts. Results The results of this study are: (1) Pregnancy is the dominant topic for female users in drug review websites and health Web forums, whereas for male users, it is cardiac problems, HIV, and back pain, but this is not the case for Twitter; (2) younger users (0-17 years) mainly talk about attention-deficit hyperactivity disorder (ADHD) and depression-related drugs, users aged 35-44 years discuss about multiple sclerosis (MS) drugs, and middle-aged users (45-64 years) talk about alcohol and smoking; (3) users from the Northeast United States talk about physical disorders, whereas users from the West United States talk about mental disorders and addictive behaviors; (4) Users with higher writing level express less anger in their posts. Conclusion We studied the popular topics and the sentiment based on users' demographics in Web-based health-related social media. Our results provide valuable information, which can help create targeted and effective educational campaigns and guide experts to reach the right users on Web

  14. Attitudinal and demographic determinants of diet quality and implications for policy targeting.

    2012-02-01

    Poor diet quality is a major public health concern that has prompted governments to introduce a range of measures to promote healthy eating. For these measures to be effective, they should target segments of the population with messages relevant to their needs, aspirations and circumstances. The present study investigates the extent to which attitudes and constraints influence healthy eating, as well as how these vary by demographic characteristics of the UK population. It further considers how such information may be used in segmented diet and health policy messages. A survey of 250 UK adults elicited information on conformity to dietary guidelines, attitudes towards healthy eating, constraints to healthy eating and demographic characteristics. Ordered logit regressions were estimated to determine the importance of attitudes and constraints in determining how closely respondents follow healthy eating guidelines. Further regressions explored the demographic characteristics associated with the attitudinal and constraint variables. People who attach high importance to their own health and appearance eat more healthily than those who do not. Risk-averse people and those able to resist temptation also eat more healthily. Shortage of time is considered an important barrier to healthy eating, although the cost of a healthy diet is not. These variables are associated with a number of demographic characteristics of the population; for example, young adults are more motivated to eat healthily by concerns over their appearance than their health. The approach employed in the present study could be used to inform future healthy eating campaigns. For example, messages to encourage the young to eat more healthily could focus on the impact of diets on their appearance rather than health. © 2011 The Authors.

    2017-09-01

    Full Text Available The aim of this paper is to compare the demographic potential of given Italian and Polish regions. The analysis shows that the demographic situation in Poland, unlike in Italy, is not directly related to the level of development of some regions and their geographical location. In Italy, the unfavorable demographic situation is typical of most of the less-developed southern regions, whereas in Poland it occurs in voivodships with different economic potential, situated in different parts of the country. This is probably the result of the current polycentric development of Poland, characteristic of a centralized economy, and the polar development in Italy. Certain demographic similarities, but of different levels, related to the dynamics of the population, the level of fertility, and net migration are observable in the macro-regions of Mezzogiorno and Eastern Poland.

    2015-01-01

    The interconnections between politics and the dramatic demographic changes under way around the world have been neglected by the two research disciplines that could contribute most to their understanding: demography and political science. Instead, this area of 'political demography' has largely been ceded to political activists, pundits, and journalists, leading often to exaggerated or garbled interpretation. The terrain includes some of the most politically sensitive and contested issues: alleged demographically determined shifts in the international balance of power; low fertility, population decline, and demographic ageing; international migration; change in national identity; and compositional shifts in politically sensitive social categories and human rights. Meanwhile many governments and non-governmental actors have actively pursued varieties of 'strategic demography', deploying fertility, mortality, or migration as instruments of domestic or international policy. Political scientists and demographers could and should use their knowledge and analytic techniques to improve understanding and to moderate excessive claims and fears on these topics.

    Full Text Available The under-representation of women on faculties of science and engineering is ascribed in part to demographic inertia, which is the lag between retirement of current faculty and future hires. The assumption of demographic inertia implies that, given enough time, gender parity will be achieved. We examine that assumption via a semi-Markov model to predict the future faculty, with simulations that predict the convergence demographic state. Our model shows that existing practices that produce gender gaps in recruitment, retention, and career progression preclude eventual gender parity. Further, we examine sensitivity of the convergence state to current gender gaps to show that all sources of disparity across the entire faculty career must be erased to produce parity: we cannot blame demographic inertia.

    Full Text Available BACKGROUND : Beta - thalassemia syndromes are a group of hereditary blood disorders characterized by reduced or absent beta globin chain synthesis , resulting in transfusion dependent severe anemia , leading to iron overload , resulting in hypothyroidism as the most common endocrine problem. OBJECTIVE : There is lack of information about frequency of hypothyroidism in thalassemic patients in ce ntral part of India , so this was undertaken to determine the frequency of hypothyroidism in patients suffering from homozygous ß - thalassemia and to study its correlation with serum ferritin and transfusion index. METHOD : This descriptive study included 60 diagnosed thalassemia major patients aged 2 - 18 years. Demographic data as well as history of blood transfusion , from which transfusion index was estimated , was taken. Serum total T3 , T4 and TSH by sandwich ELISA method using Eliscan kit , serum ferritin lev el by sandwich ELISA method using Accu - bind kit were measured from fasting blood sample. Hypothyroidism was defined by a TSH level >6.4μIU/ml. RESULTS: Study of the thyroid panel among all 60 patients showed a mean TSH level of 4.65±2.41 μIU/ml. Mean total T3 and total T4 levels were 1.35±0.48 ng/ml and 7.4±1.93 μg/dl respectively. Mean serum ferritin level was 557.25±198.66 ng/dl. Hypothyroidism was detected in 14 (23.33% out of 60 β thalassemia patients. Out of these , compensated hypothyroid (normal T3 a nd T4 with raised TSH was seen in 9 patients (15% and decompensated hypothyroid (Decrease T3 or T4 and Raised TSH was seen in 5 patients (8.33%. There was significant positive correlation of TSH levels with serum ferritin levels , age and transfusion in dex. However total T3 and total T4 did not show any correlation with serum ferritin levels , age or transfusion index. CONCLUSION : Hypothyroidism , are more common in second decade of life. Early recognition and hence prevention of these complications will d efinitely help to

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

    Science.gov (United States)

    Wane, H R

    1992-07-01

    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

    The present paper compares the distributional and risk-sharing consequences of two pension reform proposals in Germany which both aim to improve the sustainability of the current system by introducing demographic variables to the benefit calculation. While the first reform proposes a so-called "sustainability factor" which measures the changes in the dependency ratio, the second reform proposes a so-called "demographic factor" which takes into account the changes in life expectancy.

    The Amazon rain forest sustains the world's highest tree diversity, but it remains unclear why some clades of trees are hyperdiverse, whereas others are not. Using dated phylogenies, estimates of current species richness and trait and demographic data from a large network of forest plots, we show that fast demographic traits - short turnover times - are associated with high diversification rates across 51 clades of canopy trees. This relationship is robust to assuming that diversification rat...

  2. The Gender and Intergenerational Consequences of the Demographic Dividend

    OpenAIRE

    2009-01-01

    The demographic transition changes the age composition of a population, potentially affecting resource allocation at the household level and exerting general equilibrium effects at the aggregate level. If age profiles of income, consumption, and savings were stable and estimable for the entire population, they might imply how the demographic transition would affect national savings rates, but there is little agreement on the impact of age composition. These age profiles differ by gender and a...

    The identification and demographic assessment of biologically meaningful populations is fundamental to species’ ecology and management. Although genetic tools are used frequently to identify populations, studies often do not incorporate demographic data to understand their respective population trends. We used genetic data to define subpopulations in a continuously distributed species. We assessed demographic independence and variation in population trends across the distribution. Additionally, we identified potential barriers to gene flow among subpopulations. We sampled greater sage-grouse (Centrocercus urophasianus) leks from across their range (≈175,000 Km2) in Wyoming and amplified DNA at 14 microsatellite loci for 1761 samples. Subsequently, we assessed population structure in unrelated individuals (n = 872) by integrating results from multiple Bayesian clustering approaches and used the boundaries to inform our assessment of long-term population trends and lek activity over the period of 1995–2013. We identified four genetic clusters of which two northern ones showed demographic independence from the others. Trends in population size for the northwest subpopulation were statistically different from the other three genetic clusters and the northeast and southwest subpopulations demonstrated a general trend of increasing proportion of inactive leks over time. Population change from 1996 to 2012 suggested population growth in the southern subpopulations and decline, or neutral, change in the northern subpopulations. We suggest that sage-grouse subpopulations in northern Wyoming are at greater risk of extirpation than the southern subpopulations due to smaller census and effective population sizes and higher variability within subpopulations. Our research is an example of incorporating genetic and demographic data and provides guidance on the identification of subpopulations of conservation concern.

  4. Planning Marine Reserve Networks for Both Feature Representation and Demographic Persistence Using Connectivity Patterns.

    Directory of Open Access Journals (Sweden)

    Michael Bode

    Full Text Available Marine reserve networks must ensure the representation of important conservation features, and also guarantee the persistence of key populations. For many species, designing reserve networks is complicated by the absence or limited availability of spatial and life-history data. This is particularly true for data on larval dispersal, which has only recently become available. However, systematic conservation planning methods currently incorporate demographic processes through unsatisfactory surrogates. There are therefore two key challenges to designing marine reserve networks that achieve feature representation and demographic persistence constraints. First, constructing a method that efficiently incorporates persistence as well as complementary feature representation. Second, incorporating persistence using a mechanistic description of population viability, rather than a proxy such as size or distance. Here we construct a novel systematic conservation planning method that addresses both challenges, and parameterise it to design a hypothetical marine reserve network for fringing coral reefs in the Keppel Islands, Great Barrier Reef, Australia. For this application, we describe how demographic persistence goals can be constructed for an important reef fish species in the region, the bar-cheeked trout (Plectropomus maculatus. We compare reserve networks that are optimally designed for either feature representation or demographic persistence, with a reserve network that achieves both goals simultaneously. As well as being practically applicable, our analyses also provide general insights into marine reserve planning for both representation and demographic persistence. First, persistence constraints for dispersive organisms are likely to be much harder to achieve than representation targets, due to their greater complexity. Second, persistence and representation constraints pull the reserve network design process in divergent directions, making it

  5. A Statistical Assessment of Demographic Bonus towards Poverty Alleviation

    Full Text Available The shift of birth and death rates from high to low level in any population is referred as demographic transition. Mechanically, the transition of a society creates more working member of its own population commonly called demographic bonus. This articleempirically explores the realistic soundness of demographic bonus in reducing the poverty level of the society. Three contrasting regions namely Eastern Asia, Central America and Oceania were selected for analytical purposes. The findings indicate that Eastern Asia and Oceania are currently facing the end of their transition whereas theCentral America is lagged behind in transition. Central America due to last runner in transition race is the sustained recipient of its own demographic bonus by the year 2030.On the basis of three mechanisms namely: labour supply, savings and human capital, the Eastern Asian region is found to be successful beneficiary of its own demographic gift which concludes that many million people have escaped from poverty. Under the right policy environment on the above three mechanisms, Eastern Asia experience indicates the realistic contribution of demographic bonus to reduce poverty.

    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.

    MOJAVE is a long term VLBA program to investigate the kinematics and polarization evolution of a complete sample of 133 active galactic nuclei selected on the basis of compact, relativistically beamed jet emission at 15 GHz. By fitting to the apparent distributions of superluminal speed and jet luminosity, we can constrain the Lorentz factor distribution and intrinsic luminosity function of the radio-selected blazar parent population. These low-energy peaked blazars formed a significant fraction of all EGRET detections, and should figure prominently in the GLAST source catalog. Using simple models, we investigate the predicted distribution of GLAST blazars in the gamma-ray/radio flux density plane, and describe an extension of the MOJAVE survey that will provide extensive parsec-scale jet information in complete regions of this plane. We find that if a population of intrinsically radio bright yet gamma-ray weak blazars exists, its signal will be largely wiped out by the large gamma-ray flux scatter associated...

  9. Hierarchical demographic approaches for assessing invasion dynamics of non-indigenous species: An example using northern snakehead (Channa argus)

    Models of species' demographic features are commonly used to understand population dynamics and inform management tactics. Hierarchical demographic models are ideal for the assessment of non-indigenous species because our knowledge of non-indigenous populations is usually limited, data on demographic traits often come from a species' native range, these traits vary among populations, and traits are likely to vary considerably over time as species adapt to new environments. Hierarchical models readily incorporate this spatiotemporal variation in species' demographic traits by representing demographic parameters as multi-level hierarchies. As is done for traditional non-hierarchical matrix models, sensitivity and elasticity analyses are used to evaluate the contributions of different life stages and parameters to estimates of population growth rate. We applied a hierarchical model to northern snakehead (Channa argus), a fish currently invading the eastern United States. We used a Monte Carlo approach to simulate uncertainties in the sensitivity and elasticity analyses and to project future population persistence under selected management tactics. We gathered key biological information on northern snakehead natural mortality, maturity and recruitment in its native Asian environment. We compared the model performance with and without hierarchy of parameters. Our results suggest that ignoring the hierarchy of parameters in demographic models may result in poor estimates of population size and growth and may lead to erroneous management advice. In our case, the hierarchy used multi-level distributions to simulate the heterogeneity of demographic parameters across different locations or situations. The probability that the northern snakehead population will increase and harm the native fauna is considerable. Our elasticity and prognostic analyses showed that intensive control efforts immediately prior to spawning and/or juvenile-dispersal periods would be more effective

    Full Text Available Background / objectives. Hyaluronic acid (HA is rarely described in dermatomyositis (DM. Thus, we determined any clinical association of serum levels of hyaluronic acid (HA in patients with dermatomyositis (DM. Materials and Methods. This cross-sectional single-center analysis 75 DM and 75 healthy individuals, during the period from January 2012 to July 2013. An anti-HA antibody assay was performed using specific ELISA/EIA kits, according to the manufacturer’s protocol. Results. The patients with DM and control subjects had comparable demographic distributions (p>0.05. The median time duration between disease diagnosis and initial symptoms was 6.0 [3.0-12.0] months, with a median DM disease duration of 4.0 [1.0-7.0] years. The median level of serum HA was significantly increased in patients with DM compared to the control group [329.0 (80.0-958.0 vs. 133.0 (30.0-262.0 ng/mL, respectively; p0.05. Serum HA also did not correlate with gender, ethnicity, auto-antibodies or drug use (p>0.05, but did correlate with cutaneous features, such as photosensitivity (p=0.001, “shawl” sign (p=0.018, “V-neck” sign (p=0.005 and cuticular hypertrophy (p=0.014. Conclusions. A high level of serum AH was observed in DM compared to healthy individuals. In DM, HA did not correlate to demographic, auto-antibodies and therapy parameters. However, HA correlated specifically with some cutaneous features, suggesting that this glycosaminoglycan could be involved in modulating cutaneous inflammation in this population. More studies are necessary to understand the correlation between AH and patients with DM.

    Recent studies have shown that both low and high levels of serum uric acid (SUA) before cardiovascular surgery are independent risk factors for postoperative acute kidney injury (AKI). However, these studies were limited by their small sample sizes. Here, we investigated the association between SUA levels and AKI by performing a retrospective database analysis of almost 30 years of data from 81,770 hospitalized patients. Hospitalized patients aged ≥18 years were retrospectively enrolled. AKI was diagnosed according to the Kidney Disease: Improving Global Outcomes 2012 Clinical Practice Guideline (KDIGO) criteria. Multivariate logistic regression analyses were performed to investigate the independent association between SUA levels and the incidence of AKI. SUA levels were treated as categorical variables because the relationship between SUA and the incidence of AKI has been suggested to be J-shaped or U-shaped. In addition to stratified SUA levels, we considered kidney function and related comorbidities, medications, and procedures performed prior to AKI onset as possible confounding risk factors. The final study cohort included 59,219 adult patients. Adjusted odds ratios of AKI incidence were higher in both the high- and low-SUA strata. Odds ratios tended to become larger in the higher range of SUA levels in women than in men. Additionally, this study showed that AKI risk was elevated in patients with SUA levels ≤7 mg/dL. An SUA level >7 mg/dL is considered the point of initiation of uric acid crystallization. SUA level could be an independent risk factor for AKI development in hospitalized patients. Additionally, our results might suggest that intervention to lower SUA levels is necessary, even in cases of moderate elevation that does not warrant hyperuricemia treatment. Results also showed that SUA levels that require attention are lower for women than for men.

    Full Text Available Introduction: Head injury (HI is a serious morbid state caused by structural changes of the scalp, skull, and/or its contents, due to mechanical forces. Generally, the most frequent cause of HI is road traffic accident (RTA, followed by homicidal and falling injuries. The aim of present study is to assess epidemiology data, causes and patterns responsible for HI among Albanian subjects. Methodology: All HI cases (1000 are collected by the Forensic Institute of Albania, based on medical and forensic records of traumatized subjects between 2007- 2012. The prospectively-collected and descriptive information is focused on demographic data, responsible factors, type and level of cranial and brain injury, as well as their outcome. Results: The majority of HI victims were male (84% of age range of 15yrs -35yrs (70%. RTA was the HI cause in 88%, followed by homicides (3.8%, falling (3% etc. With respect to injury mechanisms, extra-dural hematoma was found in 93% of cases, followed by cerebral edema (61%, cerebral contusion (37%, skull bone fractures (35%, etc. Severe alteration of the consciousness was observed in 57% of the cases, while amnesia lasted longer than 4 weeks in 44% of the subjects included in our study. Discussion: This survey demonstrates that the majority of HI victims' is young and middle age males target group exposed to RTA. The increase of vehicles' use in placecountry-regionAlbania is more evident than RTA-related HI, indicating that driving newer vehicles with safer technology or helmets use while motorcycling can potentially decline the fatal outcome.

    The effects of age, gender, and family background on children's use of prescription psychoactive medications were studied. Patient and prescribing information was obtained for children enrolled as dependents in any of five prescription drug benefit plans during the period from December 29, 1992, through December 28, 1993. A binary response model was specified under the assumption of logistic distribution of probabilities of psychotropic drug use. The independent variables were family size, parenting type (single- or two-parent family), parental use of psychotropic medications, and child's age, gender, and the interaction between age and gender. Logistic regression analysis was conducted not only for overall psychotropic drug use but also for antidepressants, antianxiety drugs, and CNS stimulants. The sample included 3144 children; 3.9% received psychotropic drugs. Family size and parenting type had no effect on overall use of psychotropic drugs by children, but children were more likely to receive psychotropic drugs if the parents took them. The study showed an interaction between age and gender. At younger ages, boys were more likely than girls to receive psychotropic drugs; the opposite was true at older ages. For particular subcategories of drugs the study showed that (1) boys were more likely than girls, and young children were more likely than older children, to receive CNS stimulants, (2) children from single-parent families were less likely to use antidepressants than children from two-parent households, and (3) the influence of mothers' psychotropic drug use extended to all three drug classes, but the influence of fathers' psychotropic drug use existed for antidepressants only. The effects of demographic and familial factors on children's use of psychotropic drugs varied according to the drug class.

    Present study was aimed to find out dimension and socio-demographic correlates of domestic violence in Assam, Sikkim and Meghalaya, Northeast India. Two districts from each state were selected at random and women aged 18-35 years from rural and urban localities were interviewed to obtain relevant information. The study included a total of 2249 participants (Rural = 1577 and Urban = 672) from Assam (650), Sikkim (1148) and Meghalaya (451). Domestic violence was recorded in 26.4% of study participants and highest in Meghalaya. Of all types, psychological violence was predominant. A number of socio-demographic factors have been identified as independent predictors for domestic violence in pooled and state specific analysis. Findings of our study may help in formulating strategies to prevent domestic violence.

    In this paper, we present a novel approach to predict crime in a geographic space from multiple data sources, in particular mobile phone and demographic data. The main contribution of the proposed approach lies in using aggregated and anonymized human behavioral data derived from mobile network activity to tackle the crime prediction problem. While previous research efforts have used either background historical knowledge or offenders' profiling, our findings support the hypothesis that aggregated human behavioral data captured from the mobile network infrastructure, in combination with basic demographic information, can be used to predict crime. In our experimental results with real crime data from London we obtain an accuracy of almost 70% when predicting whether a specific area in the city will be a crime hotspot or not. Moreover, we provide a discussion of the implications of our findings for data-driven crime analysis.

    The objective of this research note is to introduce a training manual for event history data management. The manual provides a first comprehensive guide to longitudinal Health and Demographic Surveillance System (HDSS) data management that allows for a step-by-step description of the process of structuring and preparing a dataset for the calculation of demographic rates and event history analysis. The research note provides some background information on the INDEPTH Network, and the iShare data repository and describes the need for a manual to guide users as to how to correctly handle HDSS datasets. The approach outlined in the manual is flexible and can be applied to other longitudinal data sources. It facilitates the development of standardised longitudinal data management and harmonization of datasets to produce a comparative set of results.

    Full Text Available This paper advances a model to explain the total factor productivity in Asian countries, most of which are labor surplus and are endowed with substantial human capital. Such promising demographic potentials are considered as complementary factors to use of Information and Communication Technology (ICT. Population with such favorable demographic traits and access to ICT results in higher Total factor productivity (TFP. We call this as Demo-Tech-TFP Model and is tested by using data for 2000-2010 of 24 Asian countries. Econometric concerns like presence of endogenous and/or predetermined covariates and small time-series and cross-sectional dimensions of panel dataset are tackled by using System Generalized Method of Moments (SYS-GMM. Results show considerable support for the Demo-Tech-TFP hypothesis. Need is to design such models that suit the local demography and patterns of technological diffusion currently taking place in developing countries.

    Osteoporosis and atherosclerosis often present atypically in postmenopausal women, making clinical recognition difficult. Prospective studies suggest independent associations between bone mass and vascular calcification through vitamin D deficiency as an established predictor of both conditions. We aimed to examine the relationship between serum osteocalcin and vitamin D status in postmenopausal women with and without angiographic evidence of coronary artery disease (CAD). One hundred and eighty postmenopausal women undergoing coronary angiography were selected sequentially from the Catheterization unit of King Abdulaziz University Hospital. Socio-demographic, anthropometric parameters and dietary habits were measured. Biochemical variables were estimated in blood samples. Half of the postmenopausal women did not have significant CAD, 24% had significant CAD in a single and/or double coronary vessels, 26% had significant CAD in three coronary vessels. Mean serum vitamin D concentrations showed that vitamin D deficiency was a common finding in the whole population. Vitamin D and calcium intakes were uniformly low in the study cohort. Serum osteocalcin was significantly correlated with dietary vitamin D in all subgroups (r=-0.172, pmagnesium, alkaline phosphatase, dietary vitamin D, and body weight were independent variables of serum osteocalcin level. In conclusion, elevated levels of serum C reactive protein and vitamin D were associated with low serum osteocalcin levels. Therefore, osteocalcin may be a potential cardiovascular risk marker. However, further studies are needed to clarify the pathophysiological processes underlying the relationship between serum osteocalcin level and atherosclerosis parameters.

    To describe serum folate status and the socio-demographic correlates of serum folate status in a national sample of women aged 26-36 years in Australia, 2004-2006. Stored serum samples from 1,046 women, collected as part of the Childhood Determinants of Adult Health study, were analysed for serum folate. Median (IQR) serum folate was 27.1 nmol/L (18.8-35.0 nmol/L) with only 7.0% of samples below 11 nmol/L. Serum folate was positively associated with supplement use, educational level, occupational status and urban dwelling. In this population-based sample, most women had folate levels in the normal range with few having low serum folate. Those of lower socioeconomic position or with poorer health behaviours had lower folate levels, though most were still within the normal range. In the absence of comprehensive national survey data on the folate status of women of child-bearing age, these data provide a valuable baseline for evaluating the impact of mandatory folic acid fortification in Australia, which commenced in 2009. It is likely that mandatory fortification of the food supply with folic acid will reduce the disparities in folate status between socioeconomic groups and in people with poorer health behaviours. © 2012 The Authors.

    We hypothesized that nonsurgical-periodontal-therapy (NSPT) with adjunct Nd:YAG laser therapy is more effective in reducing periodontal inflammatory parameters (plaque index [PI], bleeding-on-probing [BOP], and probing-pocket-depth [PPD]) and serum interleukin-1beta (IL-1β) and matrix metalloproteinase-9 (MMP-9) levels in patients with and without coronary artery disease (CAD) than NSPT alone. The aim of this short-term pilot study was to assess the effect of NSPT + Nd:YAG laser therapy on periodontal parameters and serum IL-1β and MMP-9 levels in patients with and without CAD. A prospective randomized clinical study was conducted on 87 patients who were divided into two groups: Group-1: 44 patients with CAD and periodontal disease (PD) and Group-2: 43 patients with PD alone. Treatment-wise, these individuals were randomly divided into two subgroups: (i) NSPT alone and (ii) NSPT + Nd:YAG laser therapy. Demographic information was collected using a self-completed questionnaire. Periodontal parameters (PI, BOP, and PPD) and serum IL-1β and MMP-9 levels were measured at baseline and after 3 months of treatment. P-values nd serum IL-1β (P nd MMP-9 (P nd serum IL-1β, and MMP-9 levels were comparable at 3-months follow-up. NSPT + Nd:YAG laser therapy may be more effective in reducing periodontal inflammation and serum IL-1β and MMP-9 levels in patients with and without CAD than NSPT alone. Lasers Surg.

    To determine and compare the serum and tear film prolidase activity (PA) between patients with keratoconus and healthy subjects. Also, we aimed to evaluate the serum oxidative stress level and the correlation with serum PA in patients with keratoconus. This prospective, comparative clinical study included 31 patients with keratoconus and 33 age-matched and sex-matched control subjects. All participants underwent a detailed ophthalmologic examination. Serum and tear samples were obtained from all participants. Tears and serum PA and serum oxidative stress markers were measured. No significant differences in demographic characteristics were detected between groups (P > 0.05). The serum PA was significantly lower in the keratoconus group than in the control group (895.6 ± 198.7 vs. 1145.9 ± 285.4 U/L, P keratoconus group than in the control group; however, this difference was not significant (3075.4 ± 672.2 vs. 3225.8 ± 903.2 U·L⁻¹·g⁻¹ protein, P = 0.45). Oxidative stress markers, such as total oxidant status and oxidative stress index, were found to be significantly higher in the keratoconus group (P keratoconus than in the controls. Additionally, serum oxidative stress markers were found to be higher than those of the controls. Thus, prolidase and systemic oxidative stress may have a role in the pathogenesis of keratoconus.

    We examined the epidemiological associations between serum fructosamine and dyslipidemia indices in community-dwelling adults. Clinical characteristics and lipid profiles were analyzed in 1352 community-dwelling adults. The demographic characteristics and laboratory results were grouped according to the quartiles of serum fructosamine concentrations in all eligible individuals. From the bottom to the top quartile of serum fructosamine, there were graded increases in age, total cholesterol (TC), fasting blood glucose (FBG), total protein (TP), triglyceride (TG), total cholesterol/ high density lipoprotein-cholesterol (TC/HDL-C) and atherogenic index of plasma (AIP). Serum fructosamine was positive correlated with age, TC, FBG, TP, TG, TC/HDL-C and AIP in whole individuals. The positive correlations were then observed in both genders between serum fructosamine and TC, FBG, TP, TG. Two dominant factors were identified by principal component analysis. Logistic regression analysis showed that the two factors were associated with increased serum fructosamine with adjustment for gender, age, body mass index (BMI), FBG and TP. The similar results were observed in males, but not in females. Dyslipidemia tends to contribute to increased serum fructosamine concentrations in study population, suggesting that elevated serum fructosamine may herald an increased risk of cardiovascular disease among community-dwelling adults, especially in males.

    Studies on informal settlements in sub-Saharan Africa have questioned the health benefits of urban residence, but this should not suggest that informal settlements (within cities and across cities and/or countries) are homogeneous. They vary in terms of poverty, pollution, overcrowding, criminality, and social exclusion. Moreover, while some informal settlements completely lack public services, others have access to health facilities, sewers, running water, and electricity. There are few comparative studies that have looked at informal settlements across countries accounting for these contextual nuances. In this paper, we comparatively examine the differences in child vaccination rates between Nairobi and Ouagadougou's informal settlements. We further investigate whether the identified differences are related to the differences in demographic and socioeconomic composition between the two settings. We use data from the Ouagadougou and Nairobi Urban Health and Demographic Surveillance Systems (HDSSs), which are the only two urban-based HDSSs in Africa. The results show that children in the slums of Nairobi are less vaccinated than children in the informal settlements in Ouagadougou. The difference in child vaccination rates between Nairobi and Ouagadougou informal settlements are not related to the differences in their demographic and socioeconomic composition but to the inequalities in access to immunization services.

The results of the analysis. The analysis of consumer advertising texts revealed some gender peculiarities. It is confirmed that advertising for female audience is informative headlines, because it usually knows what the needed product is at the moment. It shows that an important psychological feature for women is the attention to detail that is normally ignored by men; text ads feature women is the use of a large number of emotionally charged, interrogative and incentive offers. Grounded in advertising to appeal to men innovations more often than other types of uses is provocative headlines. Semantic orientation lexicon in advertising for men focuses on external data and character traits a man on his professionalism. A small number of adjectives emphasizes restraint and courage recipient. Relative adjectives in texts predominate in advertising addressed to men and more qualitative adjectives containing the emotional evaluation of the advertised product – for women. It is proposed to take into account the physiological differences between male (analytical and female (figurative thinking: men do not like when they are run, so do not use verbs in the imperative mood, and women often act as wingmen, they need advice, call to action, so the imperative verb form is more appropriate. It is confirmed that promotional texts baby goods semantics vocabulary related to the development, nutrition, child health and feelings to it, because advertising is designed for parents and other adults.

  6. Demographic model of the Neolithic transition in Central Europe

    Full Text Available Several recent lines of evidence indicate more intensive contact between LBK farmers and indigenous foragers in Central Europe (5600–5400 calBC. Strong continuity has been identified between Mesolithic and Neolithic material cultures; faunal assemblages, and isotopic analyses of diet have revealed a greater role of hunting in LBK communities; genetic analyses have suggested that the modern Central European gene pool is mainly of Palaeolithic origin. Surprisingly little attention has been paid to demographic aspects of the Neolithic transition. In our study, demographic simulations were performed to assess the demographic conditions that would allow LBK farmers to spread across central Europe without any admixture with Mesolithic foragers. We constructed a stochastic demographic model of changes in farming population size. Model parameters were constrained by data from human demography, archaeology, and human ecology. Our results indicate that the establishment of farming communities in Central Europe without an admixture with foragers was highly improbable. The demographic conditions necessary for colonization were beyond the potential of the Neolithic population. Our study supports the integrationists’ view of the Neolithic transition in Central Europe.

    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 Angiopoietin-like protein 2 (ANGPTL2, which is mainly expressed from adipose tissue, is demonstrated to be involved in obesity, metabolic syndrome, and atherosclerosis. Because several adipocytokines are known to be associated with heart failure (HF, here we investigated the association of ANGPTL2 and HF in Taiwanese subjects.A total of 170 symptomatic HF patients and 130 age- and sex-matched controls were enrolled from clinic. The echocardiography was analyzed in each patient, and stress myocardial perfusion study was performed for clinical suspicion of coronary artery disease. Detailed demographic information, medications, and biochemical data were recorded. Circulating adipocytokines, including tumor necrosis factor-alpha (TNF-α, adiponectin, adipocyte fatty acid-binding protein (A-FABP and ANGPTL2, were analyzed. Compared with the control group subjects, serum ANGPTL2 concentrations were significantly higher in HF group patients. In correlation analyses, ANGPTL2 level was positively correlated to creatinine, fasting glucose, triglyceride, hsCRP, TNF-α, NT-proBNP and A-FABP levels, and negatively correlated with HDL-C and left ventricular ejection fraction. In multiple regression analysis, A-FABP, hsCRP, and HDL-C levels remained as independent predictors for ANGPTL2 level. To determine the association between serum ANGPTL2 concentrations and HF, multivariate logistic regression analyses were performed with subjects divided into tertiles by ANGPTL2 levels. For the subjects with ANGPTL2 levels in the highest tertile, their risk of HF was about 2.97 fold (95% CI = 1.24-7.08, P = 0.01 higher than those in the lowest tertile.Our results demonstrate a higher circulating ANGPTL2 level in patients with HF, and the upregulating ANGPTL2 levels might be associated with metabolic derangements and inflammation.

    David N Gumieiro

    Full Text Available INTRODUCTION: The aim of this study is to evaluate the serum activity of metalloproteinases (MMPs -2 and -9 as predictors of pressure ulcer (PU, gait status and mortality 6 months after hip fracture. METHODS: Eighty-seven patients over the age of 65 admitted to the orthopedic unit from January to December 2010 with hip fracture were prospectively evaluated. Upon admission, patient demographic information, including age, gender and concomitant diseases, was recorded. Blood samples were taken for analysis of MMP -2 and -9 activity by gel zymography and for biochemical examination within the first 72 hours of the patient's admission, after clinical stabilization. The fracture pattern (neck, trochanteric or subtrochanteric, time from admission to surgery, surgery duration and length of hospital stay were also recorded. RESULTS: Two patients were excluded due to the presence of pathological fractures (related to cancer, and three patients were excluded due to the presence of PU before admission. Eighty-two patients, with a mean age of 80.4 ± 7.3 years, were included in the analysis. Among these patients, 75.6% were female, 59.8% had PU, and 13.4% died 6 months after hip fracture. All patients underwent hip fracture repair. In a univariate analysis, there were no differences in serum MMP activity between hip fracture patients with or without PU. In addition, the multiple logistic regression analysis models, which were adjusted by age, gender, length of hospital stay and C-reactive protein, showed that the pro-MMP-9 complexed with neutrophil gelatinase-associated lipocalin form (130 kDa was associated with gait status recovery 6 months after hip fracture. CONCLUSIONS: In conclusion, serum pro-MMP-9 is a predictor of gait status recovery 6 months after hip fracture.

    A quantitative understanding of cities' demographic dynamics is becoming a potentially useful tool for planning sustainable growth. The concomitant theory should reveal details of the cities' past and also of its interaction with nearby urban conglomerates for providing a reasonably complete picture. Using the exhaustive database of the Census Bureau in a time window of 170 years, we exhibit here empirical evidence for time and space correlations in the demographic dynamics of US counties, with a characteristic memory-time of 25 years and typical distances of interaction of 200 km. These correlations are much larger than those observed in an European country (Spain), giving to the US a more coherent evolution. We also measure the resilience of US cities to historical events, finding a demographical post-traumatic amnesia after wars (as the Civil War) or economic crisis (as the 1929 Stock Market Crash).

    2017-01-01

    References to the second demographic transition (SDT) concept/theoretical framework have increased dramatically in the last two decades. The SDT predicts unilinear change toward very low fertility and a diversity of union and family types. The primary driver of these changes is a powerful, inevitable and irreversible shift in attitudes and norms in the direction of greater individual freedom and self-actualization. First, we describe the origin of this framework and its evolution over time. Second, we review the empirical fit of the framework to major changes in demographic and family behavior in the U.S., the West, and beyond. As has been the case for other unilinear, developmental theories of demographic/family change, the SDT failed to predict many contemporary patterns of change/difference. Finally, we review previous critiques and identify fundamental weaknesses of this perspective, and provide brief comparisons to selected alternative approaches. PMID:28798523

Despite the fact that the urban residents share in Serbia is still bellow the level of urbanization in developed countries, in which the percentage of urban residents exudes 70% (in majority of cases even more than 80%, it is an impression that demographic "resources" of rural areas have bean rather exhausted and that all demographic revitalization potential of Central Serbia is concentrated in towns. This paper treats the demographic changes which encompassed the towns of Central Serbia since 1981 census onwards, with special emphasis on the population migrations as well as on the natural growth, i.e. age - gender structure formation featuring the towns of Central Serbia. The changes will be analyzed trough a comparative analysis at the level of small, medium sized towns and big cities, while Belgrade will be represent as a special category.

    Full Text Available Abstract The use of Global Positioning Systems (GPS and Geographical Information Systems (GIS in disease surveys and reporting is becoming increasingly routine, enabling a better understanding of spatial epidemiology and the improvement of surveillance and control strategies. In turn, the greater availability of spatially referenced epidemiological data is driving the rapid expansion of disease mapping and spatial modeling methods, which are becoming increasingly detailed and sophisticated, with rigorous handling of uncertainties. This expansion has, however, not been matched by advancements in the development of spatial datasets of human population distribution that accompany disease maps or spatial models. Where risks are heterogeneous across population groups or space or dependent on transmission between individuals, spatial data on human population distributions and demographic structures are required to estimate infectious disease risks, burdens, and dynamics. The disease impact in terms of morbidity, mortality, and speed of spread varies substantially with demographic profiles, so that identifying the most exposed or affected populations becomes a key aspect of planning and targeting interventions. Subnational breakdowns of population counts by age and sex are routinely collected during national censuses and maintained in finer detail within microcensus data. Moreover, demographic and health surveys continue to collect representative and contemporary samples from clusters of communities in low-income countries where census data may be less detailed and not collected regularly. Together, these freely available datasets form a rich resource for quantifying and understanding the spatial variations in the sizes and distributions of those most at risk of disease in low income regions, yet at present, they remain unconnected data scattered across national statistical offices and websites.

    Although there is an important interaction between serotonergic system, prolactin and suicidal behavior, and impulsivity, no investigation examined the prolactin values in borderline personality disorder in which suicidal behavior and impulsivity are core symptom dimensions. In this context, in the present investigation, we planned to measure serum prolactin levels in the patients with borderline personality disorder. The study comprised 15 patients with borderline personality disorder and 15 healthy controls. Prolactin values were measured in both patients and control subjects. The patients had abnormally higher mean value of prolactin compared to those of healthy controls (48.66 ± 36.48 mg/dl for patients vs. 15.20 ± 7.81 mg/dl for healthy controls). There was no correlation between prolactin values and any demographic variables for both the patients and control subjects. In conclusion, our present results suggest that prolactin values increased in the patients with borderline personality disorder and are required to be replicated by more comprehensive and detailed further studies to decipher the exact roles of prolactin increase.

    The objectives in this article are the exploration of demographic and service usage data gained through clinical data mining audit and suggesting recommendations for social work service delivery model and future research. The method is clinical data-mining audit of 100 sequentially sampled cases gathering quantitative demographic and service usage data. Descriptive analysis of file audit data raised interesting trends with potential to inform service delivery and usage; the key areas of the results included patient demographics, family involvement and impact, and child safety and risk issues. Transport accidents involving children often include other family members. Care planning must take into account psychosocial issues including patient and family emotional responses, availability of primary carers, and other practical needs that may impact on recovery and discharge planning. This study provides evidence to plan for further research and development of more integrated models of care.

    This study investigated the relationship between consumer value and customer satisfaction, seeking a better understanding of the motivations underlying "green product" purchases. Based on the influence of demographic factors, it further explores the moderation effects of buyers' socio-demographics on the link between value and satisfaction. Data were collected through a mail survey of American hybrid car buyers. Consumer value, satisfaction, and socio-demographic information were measured, and the proposed relationships among them were tested using hierarchical multiple regression analysis. This study's findings reveal that values (i.e., functional and social) significantly impact hybrid satisfaction and that the effects vary by sex and age. This research provides insight into the motivations of green product purchases by incorporating important consumer characteristics.

    Full Text Available Montenegro as tourist destination is committed to providing a high quality experience for the tourists while carefully managing the use of a rare natural resource. In order to achieve the strategic objectives in sustainable tourism development in the future, the main focus should be given to the analysis of the main determinants of tourist satisfaction. Using a database that provides information on tourist travel behaviour and satisfaction during her/his stay in Montenegro, we have conducted empirical analysis to understand if the socio-demographic characteristics are associated with the level of tourist’s satisfaction. The effect of socio-demographic characteristics is measured through five dimensions: gender, age, country of residence, occupation and wage. Using multinomial logit model we analyze above mentioned socio-demographic characteristics and their influence on the level of tourist’s satisfaction in Montenegro.

    Both direct and indirect evidence implies that England experienced a lengthy period of stagnant or declining population during the later fourteenth and fifteenth centuries. The Black Death of 1348-1349 had brought about profound changes in England's agrarian economy, and this subsequent demographic depression is most commonly interpreted by historians as the result of plague mortality, recurring in severe outbreaks after the disease's introduction into the country. This paper reviews the evidence and assumptions behind this interpretation, in light of recent research by historical demographers and epidemiologists into bubonic plague epidemics and general mortality crises during the post-medieval period.

    analyzed complete mitochondrial genomes representing all four recognized chimpanzee subspecies and the bonobo to infer the recent demographic history and used simulations to exclude a confounding effect of population structure. Our genus-wide Bayesian coalescent-based analysis revealed surprisingly...... dissimilar demographic histories of the chimpanzee subspecies and the bonobo, despite their overlapping habitat requirements. Whereas the central and eastern chimpanzee subspecies were inferred to have expanded tenfold between around 50,000 and 80,000 years ago and today, the population size...

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

    Science.gov (United States)

    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

    Objective Psychological and physical health are often conceptualized as the absence of disease, but less research addresses positive psychological and physical functioning. For example, optimism has been linked with reduced disease risk and biological dysfunction, but very little research has examined associations with markers of healthy biological functioning. Thus, we investigated the association between two indicators of positive health: optimism and serum antioxidants. Methods The cross-sectional association between optimism and antioxidant concentrations was examined in 982 men and women from the Midlife in the United States study. Primary measures included self-reported optimism (assessed with the revised Life Orientation Test) and serum concentrations of nine different antioxidants (carotenoids and Vitamin E). Regression analyses examined the relationship between optimism and antioxidant concentrations in models adjusted for demographics, health status, and health behaviors. Results For every standard deviation increase in optimism, carotenoid concentrations increased by 3–13% in age-adjusted models. Controlling for demographic characteristics and health status attenuated this association. Fruit and vegetable consumption and smoking status were identified as potential pathways underlying the association between optimism and serum carotenoids. Optimism was not significantly associated with Vitamin E. Conclusions Optimism was associated with greater carotenoid concentrations and this association was partially explained by diet and smoking status. The direction of effects cannot be conclusively determined. Effects may be bidirectional given that optimists are likely to engage in health behaviors associated with more serum antioxidants, and more serum antioxidants are likely associated with better physical health that enhances optimism.

    A decrease in serum albumin concentrations is an almost inevitable finding in disease states, and is primarily mediated in the acute phase by alterations in vascular permeability and redistribution. This change is not disease specific but marked changes that persist are generally associated with a poorer prognosis. Critical appraisal of long-standing practices and the availability of alternative colloid solutions have led to a reduction in albumin replacement therapy, and a widespread tolerance of lower albumin concentrations in patients. The factors determining serum albumin concentrations, their measurement and the implications of hypoalbuminaemia are reviewed. The clinical value of serum albumin measurement is discussed.

    In most countries, socio-demographic factors influence the incidence of burns in children. The aims of this literature review were therefore to identify which of those factors are linked to an increase in the prevalence and identify ways of enhancing burn prevention programmes and preventing practices which play a role in the occurrence of burns in children. A comprehensive search (no time limit) of primary studies, titles and abstracts was undertaken in the following electronic databases; MEDLINE, CINAHL, ERIC, Cochrane Library, PsychInfo and Google Scholar. Socio-demographic factors which were linked to an increased incidence of burns include low household income, living in deprived areas, living in rented accommodation, young mothers, single-parent families and children from ethnic minorities. The level of parental education, parental occupation, and the type and size of accommodation were also cited. A range of socio-demographic factors result in an increase in the prevalence of burns, and the risk is even greater in children who are exposed to a number of these factors. Such information will be useful for planning prevention strategies and identifying further research questions that need to be answered.

    This study aimed to explore the association between socio-demographic factors and contraceptive use among fecund women under 25years old. This study utilized a cross-sectional data (n=3744) extracted from the Bangladesh Demographic and Health Survey 2011. Differences in the use of contraceptives by socio-demographic characteristics were assessed by χ(2) analyses. Binary logistic regression was used to identify the determinants of contraceptive use among young women. This study observed that 71% fecund women aged below 25years used contraceptives. Getting family planning (FP) methods from FP workers increases the likelihood of using contraceptives among young women because outreach activities by FP workers and accessibility of FP related information pave the way of using contraceptives. Husband-wife joint participation in decision making on health care increases the likelihood of using contraceptives. Participation of women in decision making on health care could be achieved by promoting higher education and gainful employment for women. Reproductive and sex education should be introduced in schools to prepare the young for healthy and responsible living. Moreover, policy makers should focus on developing negotiation skills in young women by creating educational and employment opportunities since husband-wife joint participation in decision making increases contraceptive use.

    The increase in the access to biomedical interventions for people living with HIV/AIDS in the developing world has not been adequately matched with the requisite psychosocial treatments to help improve the effectiveness of biomedical interventions. Therefore, in this study the author seeks to determine whether socio-demographic characteristics and social support are associated with quality of life in individuals diagnosed with HIV/AIDS in Ghana. A convenience sample of 300 HIV/AIDS support group members was obtained via cross-sectional design survey. The Medical Outcome Studies (MOS) HIV Health Survey, the MOS Social Support Survey (MOS-SSS), and demographic questionnaire instruments were used to assess quality of life, social support, and demographic information respectively. Multiple regression analysis showed that there was a positive association between overall social support and overall quality of life (r = .51). It also showed that being younger, male, attending support group meetings for over a year, and having ≥ 13 years of schooling related to higher quality of life. Implications of the findings for practice, policy, and research in Ghana and the rest of the developing world are discussed.

    Attitudes toward seeking professional psychological help (ATSPPH) are complex. Help seeking preferences are influenced by various attitudinal and socio-demographic factors and can often result in unmet needs, treatment gaps, and delays in help-seeking. The aims of the current study were to explore the factor structure of the ATSPPH short form (-SF) scale and determine whether any significant socio-demographic differences exist in terms of help-seeking attitudes. Data were extracted from a population-based survey conducted among Singapore residents aged 18-65 years. Respondents provided socio-demographic information and were administered the ATSPPH-SF. Weighted mean and standard error of the mean were calculated for continuous variables, and frequencies and percentages for categorical variables. Confirmatory factor analysis and exploratory factor analysis were performed to establish the validity of the factor structure of the ATSPPH-SF scale. Multivariable linear regressions were conducted to examine predictors of each of the ATSPPH-SF factors. The factor analysis revealed that the ATSPPH-SF formed three distinct dimensions: "Openness to seeking professional help," "Value in seeking professional help," and "Preference to cope on one's own." Multiple linear regression analyses showed that age, ethnicity, marital status, education, and income were significantly associated with the ATSPPH-SF factors. Population subgroups that were less open to or saw less value in seeking psychological help should be targeted via culturally appropriate education campaigns and tailored and supportive interventions.

  1. Who gets credit for input? Demographic and structural status cues in voice recognition.

    The authors investigate the employee features that, alongside overall voice expression, affect supervisors' voice recognition. Drawing primarily from status characteristics and network position theories, the authors propose and find in a study of 693 employees from 89 different credit union units that supervisors are more likely to credit those reporting the same amount of voice if the employees have higher ascribed or assigned (by the organization) status--cued by demographic variables such as majority ethnicity and full-time work hours. Further, supervisors are more likely to recognize voice from employees who have higher achieved status--cued by their centrality in informal social structures. The authors also find that even when certain groups of lower status employees speak up more, they cannot compensate for the negative effect of their demographic membership on voice recognition by their boss. The authors underscore how recognition of employee voice by supervisors matters for employees. It carries (mediates) the effects of voice expression and status onto performance evaluations 1 year later, which means that demographic differences in the assignment of credit for voice can serve as an implicit pathway for discrimination.

  2. The Interaction of Learning Disability Status and Student Demographic Characteristics on Mathematics Growth.

    Stevens, Joseph J; Schulte, Ann C

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

    Background: There have been speculations about the effects of hormonal changes and socio-demographic factors on periodontal health during pregnancy. Objective: According to the lack of sufficient epidemiologic information about the periodontal status of pregnant women in Yazd, this study was accomplished to determine the changes of Community Periodontal Index for Treatment Needs (CPITN) during pregnancy and evaluating the possible relationship between this index and demographic characteristics of the mothers. Materials and Methods: This was a longitudinal descriptive study. The samples included 115 pregnant women who were referred to health centers of Yazd, Iran. The mothers’ data were obtained from a questionnaire consisted of 3 parts: consent paper, demographic data and CPITN records. Examination was performed with dental unit light, flat dental mirror and WHO’s scaled probe. Results: In the beginning of the study, 60.1% of checked sextants had healthy gingival status. 25.9% had code1 and 14% had code 2. Code 3 and 4 were not seen in any sextants. There was a significant relationship between lower CPITN and higher maternal education, occupation and more frequencies of tooth-brushing but there was not a relationship between CPITN and mother’s age and number of pregnancies. CPITN had a significant relationship with increasing of the gestational age. Conclusion: There might be a relationship between increasing the month of pregnancy and more periodontal treatment needs. CPITN Increasing during pregnancy shows the importance of periodontal cares during this period. PMID:26000000

    The aim of this study was to examine the impact of demographic and cultural factors on health preferences among Chinese general population. The Chinese EQ-5D-5L valuation study was conducted between December 2012 and January 2013. A total of 1296 participants were recruited from the general public at Beijing, Chengdu, Guiyang, Nanjing, and Shenyang. Each participant was interviewed to measure preferences for ten EQ-5D-5L health states using composite time trade-off and seven pairs of states using discrete choice experiment (data were not included in this study). At the end of the interview, each participant was also asked to provide their demographic information and answers to two questions about their attitudes towards whether bad living is better than good death (LBD) and whether they believe in an afterlife. Generalized linear model and random effects logistic models were used to examine the impact of demographic and cultural factors on health preferences. Participants who had serious illness experience received college or higher education, or agree with LBD were more likely to value health states positively and have a narrower score range. Participants at Beijing were more likely to be non-traders, value health states positively, less likely to reach the lowest possible score, and have narrower score range compared with all other four cities after controlling for all other demographic and culture factors. Health state preference is significantly affected by factors beyond demographics. These factors should be considered in achieving a representative sample in valuation studies in China.

    In peripheral neuropathies, such as sensorimotor neuropathies, motor neuron diseases, or the Guillain-Barré syndrome, serum antibodies recognizing saccharide units, portion of oligosaccharides, or oligosaccharide chains, have been found. These antibodies are called anti-glycosphingolipid (GSL) or anti-ganglioside antibodies. However, the information on the aglycone carrying the hydrophilic oligosaccharide remains elusive. The absolute and unique association of GSL to the onset, development and symptomatology of the peripheral neuropathies could be misleading. Here, we report some thoughts on the matter.

    Full Text Available Objective – To investigate whether there are any demographic trends affecting student engagement with online library instruction which might have implications for practice, the authors designed a case study to examine the relationship between student demographic characteristics and engagement with online library instruction modules in English 102 courses at a single university. Methods – The authors recruited 181 students from English 102 (ENG 102, a research-based composition course, to participate in the study. ENG 102 instructors asked all participants to complete an online library instruction module embedded in the university’s course management system, either before in-person library instruction or in lieu of face-to-face library instruction. No external incentive was provided for online module completion. The research team measured levels of student engagement by recording the amount of time students spent on each page of the online module. In collaboration with the Office of Institutional Research, the authors then pulled demographic data on each participant using the university’s student information system. Pearson chi-square tests were performed to determine whether there were any notable associations between levels of student engagement and student age, grade point average, gender, and race/ethnicity. Results – Observable trends tied age and higher grade point average to higher levels of engagement with online instruction. There was additionally a slight trend linking female participants to higher levels of engagement than their male peers. In the category of race/ethnicity, the two largest subgroups, Hispanic and Caucasian students, exhibited similar levels of engagement. Conclusions – The authors conclude that there may be demographic implications for practice in designing online library instruction programs, especially when considering student age and academic performance indicators. They also conclude that, owing to

    Aneurysmal subarachnoid hemorrhage (SAH) is the most devastating form of hemorrhagic stroke. Primary predictors of mortality are based on initial clinical presentation. Initial serum lactic acid levels have been shown to predict mortality and disease severity. Initial serum lactate may be an objective predictor or mortality. Retrospective review of aneurysmal SAH in a large academic center over a 42-month period. Data collected included demographics, clinical data, serum, and clinical outcomes data. Epidemiologic data were collected at baseline, and patients were followed up through their inpatient stay. We compared data in the group of patients who were deceased (group A) vs survivors (group B). There were a total of 249 patients. Mortality was 21.5%. Mean age was the same for both groups: 57 years (group A) and 55 years (group B). Mean admission serum lactate level was 3.5 ± 2.5 (group A) and 2.2 ± 1.6 (group B; P <. 0001). The range was 0.01 to 14.7. Multivariable analysis controlling for Hunt and Hess grades showed lactic acid levels to be an independent predictor of mortality with a P value of .0018. In aneurysmal SAH, elevated serum lactate levels on admission may have a predictive role for mortality and represent a marker of disease severity. Currently, lactic acid levels are not ordered on all patients with SAH but perhaps should be part of the routine initial blood work and may serve as an additional prognostic marker.

  13. Turnover and heterogeneity in top management networks - A demographic analysis of two Swedish business groups

    Directory of Open Access Journals (Sweden)

    Collin, S. & Umans, T.

    2008-09-01

    Full Text Available A theory based on the demography of top management teams is used to explain membership turnover in two Swedish business groups, network analysis being used to define group membership. The results suggest these business groups possess a combination of financial and industrial experience as a group resource and the socialising strategy of control as a force counteracting the conflict-producing force of heterogeneity. An organisational demographic perspective focusing on opposing forces of heterogeneity and homogeneity is developed. It is shown that the perspective can be applied both to formal organisations and to informal ones such as networks.

  13. The Demographic Crisis and Global Migration - Selected Issues

    Science.gov (United States)

    Frątczak, Ewa Zofia

    2016-01-01

    Currently the world is undergoing a serious demographic shift, characterised by slowing population growth in developed countries. However, the population in certain less-developed regions of the world is still increasing. According to UN data, as of 2015, (World...2015), 244 million people (or 3.3% of the global population) lived outside their country of birth. While most of these migrants travel abroad looking for better economic and social conditions, there are also those forced to move by political crises, revolutions and war. Such migration is being experienced currently in Europe, a continent which is thus going through both a demographic crisis related to the low fertility rate and population ageing, and a migration crisis. Global migrations link up inseparably with demographic transformation processes taking place globally and resulting in the changing tempo of population growth. Attracting and discouraging migration factors are changing at the same time, as is the scale and range of global migration, and with these also the global consequences. The focus of work addressed in this paper is on global population, the demographic transformation and the role of global migrations, as well as the range and scale of international migration, and selected aspects of global migrations including participation in the global labour market, the scale of monetary transfers (remittances) and the place of global migration in the UN 2030 Agenda for Sustainable Development (Transforming...2015) and the Europe of two crises (Domeny 2016).

  19. Significance of Demographic Variables for Targeting of Internet Advertisements

    2016-06-01

    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.

  6. The impact of demographic change on intergenerational transfers via bequests

    Directory of Open Access Journals (Sweden)

    Emilio Zagheni

    2015-09-01

    Full Text Available Background: Transfers in the form of bequests have important implications for the intergenerational transmission of inequality. Demographic change has relevant consequences for the timing and size of bequests. For example, longer life implies that people receive bequests when they are older. Conversely, increasing generational length reduces the average age at which people are given bequests. Objective: We analyze the consequences of demographic change in the United States on timing over the life course when individuals receive an inheritance and on the size of bequests. Methods: We evaluate trends in life expectancy at the mean age at childbearing as a proxy for timing at receipt of bequests. We complement formal demographic analysis with empirical estimates from the Panel Study of Income Dynamics (PSID inheritance data for 1987-2010. Results: We find that the long-term trend of increasing age at receipt of bequests might have stalled, mainly because of changes in the timing of fertility. In the long term the upward trend in age at which people receive bequests may resume, as the expected linear gains in life expectancy will more than counteract recent increases in the mean age at childbearing. Conclusions: We showed that demographic change affects the size of bequests and the timing over the life course when people receive them. As the need for economic resources varies over the life cycle, changes in the timing at receipt of bequests may have a differential impact on wealth inequality and affect patterns of multigenerational transfers of resources.

    Immunoglobulin D (IgD) is the least studied of immunoglobulin classes. This study sought to investigate the potential relationship between demographic, metabolic, lifestyle and immunologic factors, and serum IgD concentrations in a general adult population. We measured serum IgD concentrations by means of a commercial turbidimetric assay in 413 individuals (median age, 55 years; 45% males), randomly selected from the adult population of a Spanish municipality. Serum IgD concentrations displayed considerable variation in the population, ranging from undetectable (immune disease after a median 11.4 years of follow-up. In conclusion, serum IgD concentrations in adults show a wide variation in the population and may be influenced by common factors, particularly age and smoking habit. These factors should be taken into account when defining reference ranges for serum IgD concentrations. This article is protected by copyright. All rights reserved.

  20. [The demographic transition in Latin America and Europe].

    Science.gov (United States)

    Zavala De Cosio, M E

    1992-12-01

    This work describes and analyzes the "European model of demographic transition" and compares it to the fertility transition in Latin America, arguing that two different types of demographic transition coexist in Latin America. Chesnais has defined 3 principal postulates of the theory of demographic transition that he believes are universally valid: the precedence in time of mortality decline; the occurrence of reproductive transition in 2 phases, limitation of marriages followed by limitation of births; and the influence of economic growth on the initiation of the secular fertiilty decline. This work is largely limited to discussion of the first 2 postulates. In all the European transitions analyzed, mortality has declined before the occurrence of fertility changes. Exceptions cited in the literature have probably been caused by omissions or other problems in the data. The level of mortality at the beginning of the transition and the rate of decline differ, giving unique character to each transition. Imbalances resulting from mortality decline are at the root of modern fertility transitions. The French demographic transition was distinguished by early appearance of birth limitation by married couples, as part of the regulation of population growth. In the rest of Europe, during the pretransitional period, the traditional system of reproduction was regulated primarily by control of nuptiality. Only at a second stage was marital fertiity controlled, when limitation of marriage was no longer sufficient or had exceeded the limits of social acceptability. All countries of Northern and Western Europe recorded increased proportions definitively single as the demographic situation began to change, until the moment when couples began to limit births. The demographic transition in Latin America began at the end of the 19th century, with mortality decline. Fertility increased initially in Latin America as it had in Europe and for the same reasons, but the impact was greater

  2. A Demographic Approach to Evaluating Tree Population Sustainability

    Directory of Open Access Journals (Sweden)

    Corey R. Halpin

    2017-02-01

    Full Text Available Quantitative criteria for assessing demographic sustainability of tree populations would be useful in forest conservation, as climate change and a growing complex of invasive pests are likely to drive forests outside their historic range of variability. 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.

    Full Text Available To evaluate the immune response to hepatitis B vaccination in stable hemodialysis (HD patients, a retro-prospective investigation was conducted on 68 HD patients. Participants were vaccinated against hepatitis B virus with an intramuscular hepatitis B vaccination schedule, 40 micrograms at 0, 1, and 6 months. The serum antibody level against hepatitis B surface antigen (HBs in HD patients was 35±55. In this study, no significant differences of Anti-HBs antibody between diabetic and non-diabetics or male and female subjects were observed. There were not any significant correlation between antibody against HBs-Ag and serum albumin. There was not significant correlation between anti-HBs antibody and age, proportion of HD, duration of HD or dialysis efficacy. In this study, there was not significant correlation between serum antibody level against hepatitis B surface antigen and some demographic indices of HD patients, however, these findings need to re-test in other centers with more participants.

    Full Text Available Background: The dearth of health and demographic data in sub-Saharan Africa from vital registration systems and its impact on effective planning for health and socio-economic development is widely documented. Health and Demographic Surveillance Systems have the capacity to address the dearth of quality data for policy making in resource-poor settings. Objective: This article demonstrates the utility of the Kintampo Health and Demographic Surveillance System (KHDSS by showing the patterns and trends of population change from 2005 to 2009 in the Kintampo North Municipality and Kintampo South districts of Ghana through data obtained from the KHDSS biannual update rounds. Design: Basic demographic rates for fertility, mortality, and migration were computed by year. School enrolment was computed as a percentage in school by age and sex for 6–18 year-olds. Socio-economic status was derived by use of Principal Components Analysis on household assets. Results: Over the period, an earlier fertility decline was reversed in 2009; mortality declined slightly for all age-groups, and a significant share of working-age population was lost through out-migration. Large minorities of children of school-going age are not in school. Socio-economic factors are shown to be important determinants of fertility and mortality. Conclusion : Strengthening the capacity of HDSSs could offer added value to evidence-driven policymaking at local level.

    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

    Presence of psychological morbidity in medical undergraduate students has been reported from various countries across the world. Indian studies to document this burden are very few. Therefore, the presence of depression, anxiety and stress among medical undergraduate students was assessed using a previously validated and standardized instrument, Depression Anxiety Stress Scale (DASS 42) and the associations with their socio-demographic and personal characteristics were identified. In a cross-sectional survey, a self-administered, pre-designed, pre-tested anonymous questionnaire including DASS 42 was used to collect information on basic socio-demographic (age, gender, semester) and personal characteristics (alcohol and tobacco use, academic performance). All students present on the day of survey were contacted for participation after obtaining informed written consent. Scores for each of the respondents over each of the sub-scales (Depression, Anxiety and Stress) were calculated as per the severity-rating index. More than half of the respondents were affected by depression (51.3%), anxiety (66.9%) and stress (53%). Morbidity was found to be more in 5 th semester students rather than students of 2 nd semester. Females reported higher score as compared to their male counterparts. Perception of self assessment in academics was strongly associated with the higher score. A substantial proportion of medical undergraduate students was found to be depressed, anxious and stressed revealing a neglected area of the students' psychology requiring urgent attention. Student counselling services need to be made available and accessible to curb this morbidity.

    Reliable information on historical and current population dynamics is central to understanding patterns of growth and decline in animal populations. We developed a maximum likelihood-based analysis to estimate spatial and temporal trends in age/sex-specific survival rates for the threatened southern sea otter (Enhydra lutris nereis), using annual population censuses and the age structure of salvaged carcass collections. We evaluated a wide range of possible spatial and temporal effects and used model averaging to incorporate model uncertainty into the resulting estimates of key vital rates and their variances. We compared these results to current demographic parameters estimated in a telemetry-based study conducted between 2001 and 2004. These results show that survival has decreased substantially from the early 1990s to the present and is generally lowest in the north-central portion of the population's range. The greatest temporal decrease in survival was for adult females, and variation in the survival of this age/sex class is primarily responsible for regulating population growth and driving population trends. Our results can be used to focus future research on southern sea otters by highlighting the life history stages and mortality factors most relevant to conservation. More broadly, we have illustrated how the powerful and relatively straightforward tools of information-theoretic-based model fitting can be used to sort through and parameterize quite complex demographic modeling frameworks. ?? 2006 by the Ecological Society of America.

    2015-02-01

    This paper presents a methodology for the development of an Urdu handwritten text image Corpus and application of Corpus linguistics in the field of OCR and information retrieval from handwritten document. Compared to other language scripts, Urdu script is little bit complicated for data entry. To enter a single character it requires a combination of multiple keys entry. Here, a mixed approach is proposed and demonstrated for building Urdu Corpus for OCR and Demographic data collection. Demographic part of database could be used to train a system to fetch the data automatically, which will be helpful to simplify existing manual data-processing task involved in the field of data collection such as input forms like Passport, Ration Card, Voting Card, AADHAR, Driving licence, Indian Railway Reservation, Census data etc. This would increase the participation of Urdu language community in understanding and taking benefit of the Government schemes. To make availability and applicability of database in a vast area of corpus linguistics, we propose a methodology for data collection, mark-up, digital transcription, and XML metadata information for benchmarking.

    2017-01-01

    We illustrate the utility of expert elicitation, explicit recognition of uncertainty, and the value of information for directing management and research efforts for invasive species, using tegu lizards (Salvator merianae) in southern Florida as a case study.  We posited a post-birth pulse, matrix model, which was parameterized using a 3-point process to elicit estimates of tegu demographic rates from herpetology experts.  We fit statistical distributions for each parameter and for each expert, then drew and pooled a large number of replicate samples from these to form a distribution for each demographic parameter.  Using these distributions, we generated a large sample of matrix models to infer how the tegu population might respond to control efforts.  We used the concepts of Pareto efficiency and stochastic dominance to conclude that targeting older age classes at relatively high rates appears to have the best chance of minimizing tegu abundance and control costs.  Expert opinion combined with an explicit consideration of uncertainty can be valuable for conducting an initial assessment of the effort needed to control the invader.  The value of information can be used to focus research in a way that not only helps increases the efficacy of control, but minimizes costs as well.

    Full Text Available A simple and cost effective business analytics schema developed in this study provides a basis for observing how demographic and commercial environmental impacts affect building control customer services. In order to overlay environmental impacts onto building control services, schematic mapping of resource distributions and services were plotted according to corporate jurisdiction, corporate virtues and customer type characteristics. Quantitative and qualitative surveys were conducted on corporate staff and material resources, business performance measures and targets, building control service manager observations and demographic and commercial environments. Results from this research provide a single view corporate map of people, material resources, and service performance in relation to customer characteristics, while reaching out to better understand the building control customer experience, general public expectation and market influences. In this regard, this research can provide a foundation for realising corporate virtue aspirations.

    Many astronomers now participate in large international collaborations, and it is important to examine whether these structures foster a scientific climate that is inclusive and diverse. The Committee on the Participation of Women in the Sloan Digital Sky Survey (CPWS) was formed to evaluate the demographics and gender climate within SDSS-IV, one of the largest and most geographically distributed astronomical collaborations. In April 2014, the CPWS administered a demographic survey to establish a baseline for the incipient SDSS-IV. We received responses from 250 participants (46% of the active membership). Half of the survey respondents were located in the US or Canada and 30% were based in Europe. Eleven percent of survey respondents considered themselves to be an ethnic minority at their current institution. Twenty-five percent of the SDSS-IV collaboration members are women, a fraction that is consistent with the US astronomical community, but substantially higher than the fraction of women in the IAU (16%)...

    Full Text Available The purpose of this study was to determine whether the use of wheeled mobility devices differed with respect to age, gender, residential setting, and health-related factors among older adults. A total of 723 adults ageing 60 and older are representing three cohorts, from nursing homes, the Center for Assistive Technology, and the wheelchair registry from the Human Engineering Research Laboratories. Wheeled mobility devices were classified into three main groups: manual wheelchairs, power wheelchairs, and scooters. Our results found factors including age, gender, diagnosis, and living settings to be associated with differences in use of manual versus powered mobility devices. Differences in use were also noted for subtypes of manual (depot, standard, and customized and powered (scooter, standard, and customized mobility devices, on demographic, living arrangements, and health-related factors. Consideration of demographic, health-related, and environmental factors during the prescription process may help clinicians identify the most appropriate mobility device for the user.

    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.

    The Amazon rain forest sustains the world's highest tree diversity, but it remains unclear why some clades of trees are hyperdiverse, whereas others are not. Using dated phylogenies, estimates of current species richness and trait and demographic data from a large network of forest plots, we show that fast demographic traits – short turnover times – are associated with high diversification rates across 51 clades of canopy trees. This relationship is robust to assuming that diversification rates are either constant or decline over time, and occurs in a wide range of Neotropical tree lineages. This finding reveals the crucial role of intrinsic, ecological variation among clades for understanding the origin of the remarkable diversity of Amazonian trees and forests. PMID:24589190

    Full Text Available The purpose of this paper is to offer a realistic perspective upon the imminent situation of demographic ageing issue in European Union. The forecasts are not reasons to major concern for the society but rather to become more responsible and not to neglect a problem that could affect our future. The demographic overview of Europe for 2011 – 2060 shows low birth rates, an increase in life expectancy and migration flows having an impact on population. As a result, the parent generation will no longer completely be replaced by the next generation of children and the narrowed active population will have to sustain a large number of persons far advanced in the age. Economic consequences of this social trend, such as increased expenditures on pensions, extended health care costs and the employment problems, are also discussed in order to define the best policy option available.

    1996-01-01

    In the aftermath of the Opium War, Britain coerced the Manchurian government into signing three treaties under which Britain occupied and leased the territory of Hong Kong and established colonial rule in the region. The rapid development of Hong Kong over the past 30 years has resulted in an increase of the territory's population from 5650 in 1841 to 6,149,000 at the end of 1994. Hong Kong now ranks fourth among the global financial centers, sixth in global foreign exchange reserve, and eighth among the world's trade systems, with per capita output of US$21,760. Demographic change and an exceptional development model were instrumental in building Hong Kong into what it has become. This paper discusses successful demographic transformation as the milestone of Hong Kong's social development, population growth as the basis of the Hong Kong government's economic strategy, and a modernized population management system as an important condition for the smooth transition of Hong Kong.

    1980-01-01

    The acceleration of demographic transition in East Asia is a process of great potential import for the world. The most rapid and large scale transformation of demographic pattern in world history is being accomplished in this region. Demographic processes in other countries and regions have been viewed in the light of past events. Demographic transition has been accepted as a desirable goal, but its realization was believed subject to certain constraints. These include the need to attain high rates of economic growth in order to stimulate the transition and the longer period of time required to accomplish the transition. It was assumed that at least 2 generations would be subject to gradually diminishing rates of increase and slow cultural modification before transition entered its last phase. This interpretation of the preconditions and specific character of demographic transition has been subject to increasing challenge, and recent events in East Asia accentuate such doubts. Most new views begin with the premises that contemporary pretransition societies are not European in culture and the 1970s are not the 1880s. East Asia also differs culturally from other developing areas, including South and Southeast Asia. The most significant regional features are cultural. Demographic transition in the region began after World War 2 and somewhat differently in each East Asian country. The process began first in Japan. The 3rd phase was accomplished rapidly but not as a specific consequence of the modernization process. The end of World War 2 and the spurt in births accompanying military demobilization contributed to a population surge. The cultural factors of practicality, homogeneity, social discipline, and nearly universial literacy were decisive here. Abortion was legalized in 1948 and other forms of birth control were made readily available. Between 1947 and 1957 the birthrate was halved to 17/1000. In Taiwan and South Korea public concern about high rates of

  4. Surviving the Holocaust: Socio-demographic Differences Among Amsterdam Jews.

    2017-01-01

    This study determined the victimisation rate among Amsterdam Jews and socio-demographic differences in surviving the Holocaust. After linking a registration list of over 77,000 Jewish inhabitants in 1941 to post-war lists of Jewish victims and survivors, the victimisation rate lies between 74.3 and 75.3 %. Differences in survival chances and risk of being killed are examined by using multivariable logistic and Cox regression analyses. While male Jews had a reduced risk of death, in the end their survival chances hardly differed from females. Though Jews aged 6-14 and 31-50 initially had a lower risk of death, in the end compared with Jews aged 15-30 they had lower survival chances, just as Jews aged 50+. For Jews aged 0-5, it was the other way around. Immigrants showed better survival chances than native Jews. German Jews showed better survival chances than Dutch Jews, but Polish and other Jewish nationals showed highest survival chances. Jews who had abandoned Judaism had better survival chances than Jews belonging to an Israelite congregation. Divorced, widowed and unmarried adult Jews had better survival chances than married Jews and their children; Jews married to non-Jews, however, had one of the highest survival chances. Jews in the two highest social classes had better survival chances than jobless Jews. These findings indicate that survival was not random but related to socio-demographic characteristics. This sheds light on demographic consequences of conflict and violence: Nazi persecution reduced the Amsterdam Jewish community drastically, and socio-demographic differences in survival impacted the post-war Jewish population structure.

    Estimates of demographic parameters such as survival and reproductive success are critical for guiding management efforts focused on species of conservation concern. Unfortunately, reliable demographic parameters are difficult to obtain for any species, but especially for rare or endangered species. Here we derived estimates of adult survival and recruitment in a community of Hawaiian forest birds, including eight native species (of which three are endangered) and two introduced species at Hakalau Forest National Wildlife Refuge, Hawaiʻi. Integrated population models (IPM) were used to link mark–recapture data (1994–1999) with long-term population surveys (1987–2008). To our knowledge, this is the first time that IPM have been used to characterize demographic parameters of a whole avian community, and provides important insights into the life history strategies of the community. The demographic data were used to test two hypotheses: 1) arthropod specialists, such as the ‘Akiapōlā‘au Hemignathus munroi, are ‘slower’ species characterized by a greater relative contribution of adult survival to population growth, i.e. lower fecundity and increased adult survival; and 2) a species’ susceptibility to environmental change, as reflected by its conservation status, can be predicted by its life history traits. We found that all species were characterized by a similar population growth rate around one, independently of conservation status, origin (native vs non-native), feeding guild, or life history strategy (as measured by ‘slowness’), which suggested that the community had reached an equilibrium. However, such stable dynamics were achieved differently across feeding guilds, as demonstrated by a significant increase of adult survival and a significant decrease of recruitment along a gradient of increased insectivory, in support of hypothesis 1. Supporting our second hypothesis, we found that slower species were more vulnerable species at the global

    Full Text Available Abstract Background Serum Krebs von den Lungen-6 (KL-6, which is classified as human mucin-1 (MUC1, is used as a marker of sarcoidosis and other interstitial lung diseases. However, there remain some limitations due to a lack of information on the factors contributing to increased levels of serum KL-6. This study was designed to investigate the factors contributing to increased levels of serum KL-6 by molecular analysis. Methods Western blot analysis using anti-KL-6 antibody was performed simultaneously on the bronchoalveolar lavage fluid (BALF and serum obtained from 128 subjects with sarcoidosis. Results KL-6/MUC1 in BALF showed three bands and five band patterns. These band patterns were associated with the MUC1 genotype and the KL-6 levels. KL-6/MUC1 band patterns in serum were dependent on molecular size class in BALF. Significantly increased levels of serum KL-6, serum/BALF KL-6 ratio and serum soluble interleukin 2 receptor were observed in the subjects with influx of high molecular size KL-6/MUC1 from the alveoli to blood circulation. The multivariate linear regression analysis involving potentially relevant variables such as age, gender, smoking status, lung parenchymal involvement based on radiographical stage and molecular size of KL-6/MUC1 in serum showed that the molecular size of KL-6/MUC1 in serum was significant independent determinant of serum KL-6 levels. Conclusions The molecular structural variants of KL-6/MUC1 and its leakage behavior affect serum levels of KL-6 in sarcoidosis. This information may assist in the interpretation of serum KL-6 levels in sarcoidosis.

    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.

    Full Text Available INTRODUCTION Currently available evidence reveals comparatively few studies of psychological effects of hearing impairments, in spite of the fact that clinicians have for a long time been aware of a connection between the acquired hearing impairment and mental disorders. They are focused on the investigation of dysfunction in general. Thus, three domains of the auditory imbalance may be distinguished: disorder, disability and handicap. 'Handicap', according to the definition of the World Health Organization, is a hindrance in an individual that results from an impairment or disability and represents psychological response of the individual to the impairment. OBJECTIVE Validation of acquired hearing impairment as a risk factor of psychical disorders as well as an analysis of relation of some demographic factors (sex, age, education and audiological factors (degree and duration of the impairment with the frequency of hearing handicap. METHOD MMPI-201 has been applied in 60 subjects affected with otosclerosis, potential candidates for stapedectomy, before and after the surgery. RESULTS Individuals with acquired hearing impairment manifest more frequent disorders of psychical functioning in comparison with general population, while demographic and audiometric parameters did not correlate with acquired hearing handicap. CONCLUSION It may be assumed that the very recognition of demographic and audio-logical factors can not help much in the understanding of the psychological stress associated with hearing impairment.

    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.

    di Crescenzo, Giovanni

    An improved understanding of the identity theft problem is widely agreed to be necessary to succeed in counter-theft efforts in legislative, financial and research institutions. In this paper we report on a statistical study about the existence of relationships between identity theft and area demographics in the US. The identity theft data chosen was the number of citizen complaints to the Federal Trade Commission in a large number of US municipalities. The list of demographics used for any such municipality included: estimated population, median resident age, estimated median household income, percentage of citizens with a high school or higher degree, percentage of unemployed residents, percentage of married residents, percentage of foreign born residents, percentage of residents living in poverty, density of law enforcement employees, crime index, and political orientation according to the 2004 presidential election. Our study findings, based on linear regression techniques, include statistically significant relationships between the number of identity theft complaints and a non-trivial subset of these demographics.

    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.

    A clinical blood serum mercury test of 111 dentists and auxiliaries revelaed that more than 50% had above normal serum mercury levels. This study showed that there may be a mercury health hazard in some dental environments. Acute mercury poisoning may be corrected simply by removing the cause, but long-term chronic effects are not known. Frequent screening of offices and personnel is advised. Experience reported here indicates that large amounts of mercury vapor are emitted when an amalgam carrier is heated over a flame ot dislodge particles, and also, that water-covered amalgam scrap relesases mercury vapor.

    Full Text Available OBJECTIVE: Uric acid is the end product of purine metabolism in humans, and increased serum uric acid concentrations lead to gout. The objective of the current study was to identify factors that are independently associated with serum uric acid concentrations in a cohort of Czech control individuals. METHODS: The cohort consisted of 589 healthy subjects aged 18-65 years. We studied the associations between the serum uric acid concentration and the following: (i demographic, anthropometric and other variables previously reported to be associated with serum uric acid concentrations; (ii the presence of metabolic syndrome and the levels of metabolic syndrome components; and (iii selected genetic variants of the MTHFR (c.665C>T, c.1286A>C, SLC2A9 (c.844G>A, c.881G>A and ABCG2 genes (c.421C>A. A backward model selection procedure was used to build two multiple linear regression models; in the second model, the number of metabolic syndrome criteria that were met replaced the metabolic syndrome-related variables. RESULTS: The models had coefficients of determination of 0.59 and 0.53. The serum uric acid concentration strongly correlated with conventional determinants including male sex, and with metabolic syndrome-related variables. In the simplified second model, the serum uric acid concentration positively correlated with the number of metabolic syndrome criteria that were met, and this model retained the explanatory power of the first model. Moderate wine drinking did not increase serum uric acid concentrations, and the urate transporter ABCG2, unlike MTHFR, was a genetic determinant of serum uric acid concentrations. CONCLUSION: Metabolic syndrome, moderate wine drinking and the c.421C>A variant in the ABCG gene are independently associated with the serum uric acid concentration. Our model indicates that uric acid should be clinically monitored in persons with metabolic syndrome.

    Full Text Available Purpose: Employee turnover presents arguably the biggest threat to business sustainability and is a dynamic challenge faced by businesses globally. In South Africa, organisations compete to attract and retain skilled employees in an environment characterised by a burgeoning skills deficit. Turnover risk management is becoming an important strategy to ensure organisational stability and promote the effective retention of employees. The purpose of this research was to contribute to the practice of turnover risk management by proposing an approach and constructing a model to predict employee turnover based on demographic characteristics readily available in a human resource information system.Design: An exploratory research design was employed. Secondary quantitative data were extracted from an existing human resources database and analysed. Data obtained for 2592 employees in a general insurance company based in South Africa and Namibia formed the basis for the analysis. Logistic regression analysis was employed to predict employee turnover using various demographic characteristics available within the database. A likelihood ratio test was used to build a predictive model and the Akaike information criterion and Schwarz criterion were used to test how much value each variable added to the model and if its inclusion was warranted. The model was tested by conducting statistical tests of the significance of the coefficients. Deviance and Pearson goodness-of-fit statistics as well as the R-square test of significance were used. The overall goodness-of-fit of the model was also tested using the Hosmer and Lemeshow goodness-of-fit test.Findings: The current findings provide partial support for a predictive model explaining employee turnover. The model tested 14 demographic variables and the following five variables were found to have statistically significant predictive value: age, years of service, cost centre, performance score and the interaction

    We have already shown that the concentration of secreted form of Klotho decreases in the cerebrospinal fluid of patients with relapsing-remitting multiple sclerosis (RRMS). The current study aimed at assessing possible changes in the serum Klotho concentration of MS patients. Participants involved 15 new cases of RRMS patients in the relapse phase, 15 RRMS patients who had been suffering from the disease for more than three years and were under regular treatments (interferon beta-1a) and, finally, 15 non-MS patients who constituted the control group. Beside thorough neurological examinations, demographic and clinical data (e.g. gender, age, duration of disease and expanded disability status scale) were obtained. Serum Klotho concentration was measured using ELISA method. The results showed no statistically meaningful difference between new cases of RRMS (585.56pg/ml±153.99) and control group (556.81pg/ml±120.36; P=0.859). The serum Klotho level, however, was significantly higher in patients with prolonged disease duration (696.94pg/ml±170.52; P=0.037) in comparison with the subjects in the control group. In conclusion, this study showed that serum Klotho concentration tends to be higher in MS patients when compared to control group. This finding might be attributed to treatment of MS patients with immunomodulatory drugs or a compensatory response to enhance CNS regeneration and/or vitamin D biosynthesis. Further studies are required to elucidate the role of Klotho in MS pathophysiology.

    Abstract Recent studies demonstrated an adverse effect of chronic exposure to air pollution (AP) on metabolic syndrome and its components. In a population-based study, we investigated the association between exposure to ambient AP and serum glucose (SG), among subjects with normal glucose, impaired fasting glucose (IFG), and diabetes mellitus (DM). We included 1,063,887 SG tests performed in 131,882 subjects (years 2001–2012). Exposure data included daily levels of SO2, NO2 and other pollutants of industrial, traffic, and nonanthropogenic sources. Demographical, clinical, and medications purchase data were assessed. Log-transformed SG levels were analyzed by linear mixed models adjusted for seasonal variables and personal characteristics. SG increases (%increase [95% CI]), among subjects with normal glucose, IFG, and DM, respectively, were associated with 6.36 ppb increase of NO2 measured 24 to 72 hours before the test (0.40% [0.31%; 0.50%], 0.56% [0.40%; 0.71%], and 1.08% [0.86%; 1.29%]); and with 1.17 ppb increase of SO2 measured 24 hours before the test (0.29% [0.22%; 0.36%], 0.20% [0.10%; 0.31%], and 0.33% [0.14%; 0.52%]). Among DM population, weakest association was observed among patients treated with Metformin (0.56% increase in SG [0.18%; 0.95%]). In conclusion, NO2 and SO2 exposure is associated with small but significantly increased levels of SG. Although DM patients were found to be more susceptible to the AP induced SG variations, Metformin treatment seem to have a protective effect. Given the chronic lifetime exposure to AP and the broad coverage of the population, even small associations such as those found in our study can be associated with detrimental health effects and may have profound public health implications.

    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

    Insects that should be considered for conservation attention are often overlooked because of a lack of data. The detailed information necessary to assess population growth, decline, and maximum range is particularly difficult to acquire for rare and cryptic species. Many of these difficulties can be overcome with the use of life table analyses and heat energy accumulation models common in agriculture. The wekiu bug (Nysius wekiuicola), endemic to the summit of one volcanic mountain in Hawaii, is a rare insect living in an environmentally sensitive alpine stone desert, where field-based population assessments would be inefficient or potentially detrimental to natural and cultural resources. We conducted laboratory experiments with the insects by manipulating rearing temperatures of laboratory colonies and made detailed observations of habitat conditions to develop life tables representing population growth parameters and environmental models for wekiu bug phenology and demographic change. Wekiu bugs developed at temperatures only found in its environment on sunny days and required the thermal buffer found on cinder cones for growth and population increase. Wekiu bugs required approximately 3.5 months to complete one generation. The bug developed optimally from 26 to 30 °C, temperatures that are much higher than the air temperature attains in its elevational range. The developmental temperature range of the species confirmed a physiological reason why the wekiu bug is only found on cinder cones. This physiology information can help guide population monitoring and inform habitat restoration and conservation. The wekiu bug was a candidate for listing under the U.S. Endangered Species Act, and the developmental parameters we quantified were used to determine the species would not be listed as endangered or threatened. The use of developmental threshold experiments, life table analyses, and degree day modeling can directly inform otherwise unobservable habitat needs and

    Full Text Available BACKGROUND: Previous studies suggested that alterations in serum cortisol and DHEA-S levels may play a role in the pathophysiology of schizophrenia. AIM: To compare serum cortisol and DHEA-S levels between patients with schizophrenia and healthy controls and to evaluate their association with the response to antipsychotic treatment. MATERIAL AND METHODS: In this clinical prospective study were included 60 patients with schizophrenia and 40 healthy age and sex matched control subjects. Clinical evaluation of patients was performed using the Positive and Negative Symptom Scale. A questionnaire for socio-demographic and clinical data collection was used. For the purposes of the study, the examined group was divided in two subgroups: responders and nonresponders. Serum cortisol and DHEA-S levels were measured at baseline in all participants and after 3 and 6 weeks of the antipsychotic treatment in patients with schizophrenia. RESULTS: Patients with schizophrenia had significantly higher serum cortisol and DHEA-S levels in comparison to the control group. Responders had significantly higher serum cortisol and DHEA-S levels compared with nonresponders. CONCLUSION: Elevated serum cortisol and DHEA-S levels may play a role in the pathophysiology of schizophrenia and they may be related to positive response to antipsychotic treatment in patients with schizophrenia.

    Data from experimental animal nutrition and animal husbandry indicate that several trace minerals, including copper (Cu) are involved in bone metabolism. In addition, a large body of data suggests that low dietary calcium (Ca) intake is a risk factor for age related bone loss. The authors measured the serum (Cu), dietary Ca intake (dCa) and bone mineral density (BMD) in the spine of 225 postmenopausal women. The median dCa and serum (Cu) were 562 mg/d and 9.73 umoles/L, respectively. Serum (Cu) but, not dCa, was greater in subjects with a history of estrogen therapy (ERT). BMD was higher in subjects with above median dCa and serum (Cu) (group 1) compared to those with below median values (group 2). BMD was intermediate for subjects with either Low serum (Cu):High dCa or High serum (Cu):Low dCa. This relationship was observed in the subject group as a whole, as well as in subgroups partitioned according to history of ERT. Groups 1 and 2 did not differ in basic demographic characteristics such as age, age at menopause, body weight and height. These data support the hypothesis that Ca and Cu nutriture are determinants of skeletal health in postmenopausal women.

    Serum levels of ferritin are commonly measured to assess iron stores but are affected by factors such as obesity and chronic disease. Published reference ranges have not changed in decades, and the number of patients whose levels exceed the upper limits has been increasing. As a result, more patients are evaluated for iron overload. We compared serum levels of ferritin in 1188 Australian adults who participated in the 2005 Busselton Population Survey with levels from the 1995 survey. Parametric regression was used to assess the effects of body weight and biochemical parameters on serum level of ferritin to derive contemporary population-appropriate reference ranges. In 2005, age-adjusted levels of ferritin were 21% higher in men (P ferritin in men ≥35 years old and in postmenopausal women (P ≤ .002). Serum level of γ-glutamyltransferase (GGT) correlated with serum level of ferritin (P Serum levels of ferritin increased significantly between 1995 and 2005. Reference ranges that accommodate demographic and biomedical variations will assist clinicians in identifying individuals who require further evaluation for iron overload.

    Systemic Fe overload can contribute to abnormal glucose metabolism and the onset of type 2 diabetes (T2D). Although hepcidin is the master regulator of systemic Fe homeostasis, few studies have systematically evaluated the associations of serum hepcidin concentrations with Fe metabolism parameters and risks for the development of T2D. In this regard, whether hepcidin concentrations are associated with T2D remains controversial. We measured serum hepcidin and ferritin concentrations in a case-control study of 1259 Han Chinese participants to evaluate the possible associations of serum hepcidin concentrations with Fe metabolism parameters and risks of T2D. Individuals with diabetes (n 555) and control participants (n 704) were recruited and serum hepcidin and ferritin concentrations were quantified. Additionally, selected biochemical and anthropometric variables were determined. A logistic regression analysis was performed to evaluate the association of serum hepcidin and ferritin concentrations with T2D. A linear regression analysis was used to test for associations between serum hepcidin and ferritin concentrations and a number of clinical, demographic and diabetes-associated variables. We found that serum hepcidin concentrations correlated with Hb and serum ferritin concentrations. No differences in hepcidin concentrations were found between the group with diabetes and the control group. Hepcidin concentrations were not significantly correlated with T2D risk factors. We also found that serum ferritin concentrations were elevated in individuals with diabetes and were positively correlated with both Hb concentrations and T2D risk factors. The present findings suggest that serum ferritin concentrations correlate with T2D risk factors, while serum hepcidin concentrations are positively associated with Hb and serum ferritin concentrations, but do not correlate with T2D.

  20. Serum amyloid a in clinical practice

    Full Text Available Serum amyloid A (SAA is an acute phase first class protein discovered a quarter of the century ago. Its concentration depends on clinical findings of the patient, illness activity and the therapy applied. SAA increases moderately to markedly (100-1000 mg/l in bacterial and fungal infections, invasive malignant diseases, tissue injuries in the acute myocardial infarction and autoimmune diseases such as rheumatoid arthritis and vasculitis. Mild elevation (10-100 mg/l is often seen in viral infections, systemic lupus erythematosus and localized inflammation or tissue injuries in cystitis and cerebral infarction. SAA as sensitive, non-invasive parameter is used in organ transplantation where early and correct diagnosis is needed as well as where prompt therapy is required. Besides acute kidney allograft rejection, SAA is used in the diagnosis of rejection after liver transplantation, simultaneous pancreas and kidney transplantation and also in bone marrow transplantation (acute „graft vs. host disease". Simultaneous determination of C-reactive protein (CRP and SAA may point to acute kidney allograft rejection. Standard immunosuppressive therapy with cyclosporine A and prednisolone significantly suppresses the acute phase CRP reaction both in operation itself and acute rejection, but not in infection. On the other hand, SAA rejection in operation, acute allograft rejection and infection is present in spite of cyclosporine A and steroids therapy. Different reaction of SAA and CRP in transplant patients to cyclosporine A therapy helps in differentiation between the infection and rejection. Although CRP and SAA are sensitive and acute phase reactants, their serum concentrations cannot be valued as prognostic and diagnostic criteria without creatinine serum concentration and clinical findings. In addition, they offer important information for clinical diagnosis as well as the kind of therapy.
