    While women’s labor force participation tends to increase with economic development, the relationship is not straightforward or consistent at the country level. There is considerably more variation across developing countries in labor force participation by women than by men. This variation is driven by a wide variety of economic and social factors, which include economic growth, education, and social norms. Looking more broadly at improving women’s access to quality employment, a critica...

  11. The labor force of the future.

    Science.gov (United States)

    Norwood, J L

    1987-07-01

    In the decades ahead, the US labor force will reflect changes in the industrial structure, with declines in some manufacturing industries and expansion in service industries. The services sector is so diverse that the jobs within it cannot be categorized as either high wage or low wage. The service-producing sector employs 85% of professional specialty workers in the US. In general, information on compensation trends indicates that greater increases in compensation have occurred for workers in service-producing as opposed to goods-producing industries. The increase in service sector jobs has created opportunities for women to enter the labor force and, at present, 5 out of 6 women work in this sector compared to fewer than 2 out of 3 men. Productivity growth rates in the service-producing industries vary substantially and are strongly affected by the business cycle. Central to employment opportunities in the years ahead will be the effect of new technology. To date, the aggregate effect of new technology has been increased employment and higher living standards. Although retraining programs should be in place, the scenario of a huge technology-created labor surplus seems unlikely. In fact, a more likely problem is a shortage of labor resulting from earlier labor force withdrawal and demographic aging of the population. Those in the 25-54-year age group will represent a larger share of the labor force in the years ahead. In addition, blacks are expected to account for 20% of the labor force growth in the next decade. Finally, given increasing labor force participation rates among mothers, employers may have to provide more flexible work schedules, assistance with day care, and more attractive benefits packages.

  12. Determinants of Female Labor Force Participation

    Directory of Open Access Journals (Sweden)

    Dr. Adiqa Kausar Kiani

    2009-12-01

    Full Text Available There are many factors related to female entering the labor market. For example, household income, household expenditure, education and status of the head of the household (male/ female. The degree of correlation between each variable and female labor force participation rate varies throughout the country. This study focused on the factors due to which women enter in labor market. Tobit model is used for this analysis. It is concluded that education and household expenditures have positive but insignificant impact on the female LF, whereas household income and head of the household has negative impact on FLF. It is suggested that in order to improve the working condition of female labor force government should take necessary action, for example women education etc.

  13. Forced Labor during the Romanian Holocaust

    2012-10-01

    Full Text Available My paper aims to retrieve and present in general lines one aspect of the Romanian Holocaust that was since recently ignored by most scholars in the field, namely the forced labor of the Jewish population. Part of the deliberate anti-Jewish policy of the Antonescu government, the issue of forced labor is relevant as it completes the picture of the Holocaust in Romania, at the same time indicating the border between the Romanian apartheid society and the Romanian genocidal state. The paper thus points at the necessity for the scholars to continue their research in the field of holocaust studies at large, a topic that is far from exhausting its resources and significance.

    Gold mining brought a forced labor system to Witwatersrand, South Africa, in the 1880s as African laborers were rounded up from the hinterland and delivered to the mines. The system produced low wages, high mortality, and the loss of chances for upward mobility. Forced labor persists today in South African mines. (VM)

    This paper sets the groundwork for analysis of the effect of selection into labor force on gender unemployment gaps. We derive the Manski bounds for gender unemployment gaps in 21 EU countries and show that in addition to the positive selection documented in the gender wage gap research, there is also evidence of negative selection into the labor force among women after childbirth. While positive selection of women into the labor force leads to downward bias in gender unemployment gaps, negat...

    The study examines the labor-force behavior of Israelis at older ages, focusing on the determinants of the transitions between states of labor-force participation between 2005 and 2010. The study uses panel data from the first two waves of the SHARE-Israel longitudinal survey. A multinomial logit model is used to examine the impact of sociodemographic characteristics, health state, and economic resources on labor-force transitions of people aged 50-67. The results emphasize the role of age and poor health in "pushing" older people out of the labor force or "keeping" them there. Spouse's participation is found to encourage individuals to leave the labor force or to refrain from joining it. However, living with a participating spouse is negatively associated with staying out of the labor force, consistent with the dominance of the complementarity of leisure effect found in the literature. Wealth as an economic resource available to individuals for retirement is also found to encourage individuals to leave the labor force or to refrain from joining it.

    2012-01-01

    Labor-market transitions toward the latter parts of workers’ careers can be complex, with movement between jobs and classes of work and in and out of retirement. The authors analyzed factors associated with the labor-market transitions of older workers to self-employment from unemployment or disability, retirement, or wage and salary work using rich panel data from seven waves of the Health and Retirement Study (HRS). They found evidence that (prior) job characteristics and liquidity constraints are important predictors of movements to self-employment for workers and nonworkers, while risk aversion is a significant predictor only for workers.

  6. Economic crisis and women's labor force return after childbirth: Evidence from South Korea

    Directory of Open Access Journals (Sweden)

    Li Ma

    2014-08-01

    Full Text Available Background: Most research on women's labor force return after childbirth concentrates on industrialized countries in the West; the link between economic swings and mothers' work-return behavior is rarely addressed. This study closes these gaps by focusing on South Korea, a developed society in East Asia that has in recent decades witnessed increases in female labor force participation and dramatic economic ups and downs. This is the first relevant study on South Korea. Objective: This study examines how women's labor force return after childbirth (with and without career interruption and their career prospects upon work return varied before, during, and after the Asian financial crisis in South Korea. Methods: Logistic and hazard regression models were applied to the Korea Labor and Income Panel Study (KLIPS waves 1-10. Results: The study reveals an increase in women's immediate work return after childbirth without career interruption since the 1980s. The Asian financial crisis boosted this immediate return pattern. The implementation of job-protected maternity leave further contributed to this pattern. Women who underwent career interruption at first birth were also more likely to re-enter the labor market during and after the crisis than before. Downward occupational moves were especially common during the period of financial crisis. Conclusions: The results suggest that the Asian financial crisis triggered a noticeable change in women's post-birth work-return behavior. The economic volatility pushed mothers to hold onto their role in the labor force more strongly than before.

    The five-fold increase in the labor force participation rate of married women over the last half century was not accompanied by a substantial increase in the average job market experience of working women. Two data sets giving life-cycle labor force histories for cohorts of women born from the 1880s to 1910s indicate substantial (unconditional) heterogeneity in labor force participation. Married women in the labor force had a high degree of attachment to it; increased participation rates brou...

  10. Trends in female labor force participation in Sweden.

    Science.gov (United States)

    Gustafsson, S; Jacobsson, R

    1985-01-01

    The labor force participation of Swedish married women increased form 49.1% to 83.5% in the past 2 decades. Results from cross section analyses carried out on micro data from 3 standard of living investigations, done in 1968, 1974, and 1981, are used to predict changes over time. Women's real wages have increased over time more than men's real wages; in combination with estimated positve own wages elasticities, this change is the most important determinant of the increase in female labor supply. The labor force participation of married women ages 20-59 has increased from 49.1% in 1963 to 83.5% in 1982; the increase is especially large for women with children under 7. Over the decades 1920-1965, when real wages of woman increased more than real incomes of men, the labor force participation rates of married women increased even faster. From 1963-1981 a dramatic narrowing of the male-female wage gap occurred; most of the decrease is a result of factors other than the human capital variables accumulated at school and on the job. The effect of centralized collective bargaining and a strong union policy to increase low wages may be important explanatory factors. Generous parental leaves and subsidized day care may have an increasing effect on fertility; but instead, fertility has decreased, perhaps less than it might have done in the absence of such policies. By using individual cross section data from the 3 standard of living investigations, estimates of participation are performed. The own wage effects of the participation equation are positive and significant but decreasing over time. Important institutional changes between the sample periods are the extended parental leaves and the increased supply of government subsidized day care.

  11. Changing Structures and Women’s Role as Labor Force

    Directory of Open Access Journals (Sweden)

    Lena Gonäs

    2015-06-01

    Full Text Available The objective of this paper is to analyze changes in the development of women’s role as labor force over a 40-year period. This is done by presenting research results that concern the restructuring of the labor market over different time periods. The empirical material is from the 1960s, the heyday of the Swedish model; from the 1980s, the period that economic historians label the third industrial revolution; and from the 1990s, a period labeled the new working life that is covering the reorganization of the public sector. For the first period results from restructuring in the shipyard industry are presented as well as employment outcomes for single individuals. This industry was male dominated with very few women employed, but regional policy measures were implemented to reach a latent female labor force. The second period is covered by a study of closures and cutbacks in different industries in Sweden during 1982–1983. The proportion of women employed in the industries studied was around one third and employment outcomes had a specific gendered pattern. Women did to a lower extent than men get new permanent jobs. Permanent temporariness was introduced as a concept to describe their labor market situation. The recession that one decade later hit both female- and male-dominated sectors is illustrated by a study of the relations between labor market attachment, working life, and family conditions. The material comes from a regional research program based on a questionnaire and on register data on incomes from 1990 to 1999. The paper analyzes several areas related to work and outside of work that indicate a gendered pattern of multidimensional subordination and an increased polarization in terms of both gender and class. In conclusion, the 40 years has been a period of dramatic change in women’s situation as labor force. In times of restructuring they often entered into precarious job situations or unemployment.

  12. CHALLENGES OF AGING LABOR FORCE IN AN ORGANIZATION

    Directory of Open Access Journals (Sweden)

    Marjan Petrišič

    2013-09-01

    Full Text Available This paper examines the impacts of the changes of the composition of the ageing labor force on the skills and knowledge transfer in an organization. The changing individual needs of older individuals are creating powerful, labor dynamic incentives. For the management organizations from private and public sector, this is an organizational challenge linked to cultural transformation on the level of organization. The results of the study show that the manager and non-manager respondents have the unique aspect of the role of senior employees in some small Slovenian organizations. Managers in the sample based on their managerial experience, see the older workers in an organization primarily as transformers of jobs to younger employees, which should be courteous and efficient and should help the organization competitiveness. Non – managers’ respondents give priority to employment and retirement strategy for senior employees and maintain a positive view of older employees’ motives and productivity. Further, non – managers point to the need to keep older workers with unique skills and competences in an organization. We conclude that organizations will meet the challenge of ageing labor force in the near future. They will have to start the organizational culture, which will promote business change and continuous flow of skills and competences through inter-generation model.

  13. The gravity model of labor migration behavior

    Science.gov (United States)

    Alexandr, Tarasyev; Alexandr, Tarasyev

    2017-07-01

    In this article, we present a dynamic inter-regional model, that is based on the gravity approach to migration and describes in continuous time the labor force dynamics between a number of conjugate regions. Our modification of the gravity migration model allows to explain the migration processes and to display the impact of migration on the regional economic development both for regions of origin and attraction. The application of our model allows to trace the dependency between salaries levels, total workforce, the number of vacancies and the number unemployed people in simulated regions. Due to the gravity component in our model the accuracy of prediction for migration flows is limited by the distance range between analyzed regions, so this model is tested on a number of conjugate neighbor regions. Future studies will be aimed at development of a multi-level dynamic model, which allows to construct a forecast for unemployment and vacancies trends on the first modeling level and to use these identified parameters on the second level for describing dynamic trajectories of migration flows.

  18. Corruption and economic growth with non constant labor force growth

    Science.gov (United States)

    Brianzoni, Serena; Campisi, Giovanni; Russo, Alberto

    2018-05-01

    Based on Brianzoni et al. [1] in the present work we propose an economic model regarding the relationship between corruption in public procurement and economic growth. We extend the benchmark model by introducing endogenous labor force growth, described by the logistic equation. The results of previous studies, as Del Monte and Papagni [2] and Mauro [3], show that countries are stuck in one of the two equilibria (high corruption and low economic growth or low corruption and high economic growth). Brianzoni et al. [1] prove the existence of a further steady state characterized by intermediate levels of capital per capita and corruption. Our aim is to investigate the effects of the endogenous growth around such equilibrium. Moreover, due to the high number of parameters of the model, specific attention is given to the numerical simulations which highlight new policy measures that can be adopted by the government to fight corruption.

  19. Fertility and patterns of labor force participation among married women.

    Science.gov (United States)

    Smith-Lovin, L; Tickamyer, A R

    1981-01-01

    Variations in women's response to childbearing and participation in the labor force are examined with the expectation that 2 distinct patterns will emerge clarifying the fertility-work effect. The hypothesis is offered that 1 group of women will drop out entirely at the onset of childbearing, returning to work after the children have grown, if at all. Another group will work almost continuously with almost no gap in labor force participation. Past research, concentrating on averaged direction of causal flow, have obscured this bimodal distribution. 3 problems hamper the study of fertility effects on career discontinuity: detailed work and birth histories covering extended periods of time are scarce, variables often obscure variability, and censored histories are frequent in which the timing of an event may or may not occur until after the survey and therefore cannot be observed. Data for the analysis are from the 1970 EEO survey (Explorations in Equaltiy of Opportunity), a national sample survey of women who were high school sophomores in 1955. Using only complete data from women who were still married to their 1st husbands yielded a sample size of 703. Of these, 39% were working in 1970 and 85% had 2 or more children. Employment status, recorded for each year, was a dichotomous variable distinguishing between no employment during the year and any employment. The fertility variable indicated if a child was or was not adopted or born during the year. The women were much more likely to work before their 1st birth than afterwards, at least during the early adult years covered by this survey. Women who began childbearing while still in high school were more likely to continue working after birth. College graduates were also somewhat more likely to continue working after their 1st birth. 70% of the women worked before their 1st birth, 30% after the onset of childbearing. Work discontinuity, measured by the number of gaps in employment indicate that over 50% of the

    Abstract: This paper analyzes labor market behavior of urban Eritrean women with particular reference to the impact of education, earnings and labor market opportunities. Unlike traditional models of labor supply, which assume that work can be supplied freely in the labor market, we develop a framework that explicitly takes into account the notion of job opportunities and observable sets of feasible jobs. The framework is formulated within a random utility setting in which unob...

Women tend to assume more family duties than men and, consequently, often participate less in the labor market. At the same time, family policies are to provide support to families while also helping women to reconcile family duties with labor market participation. Their impact, however, is not clear, especially when it comes to ...

    The labor force participation rate is an important indicator of the state of the labor market and a major input into the economy's potential for creating goods and services. The objectives of this paper are to examine the prevalence of labor force participation among older people in Thailand and to investigate the factors affecting this participation. The data for this study were drawn from the '2007 Survey of Older Persons' in Thailand. Bivariate analysis was used to identify the factors associated with labor force participation. The variables were further examined using multivariate analysis in order to identify the significant predictors of the likelihood of older people participating in the labor force, after controlling for other variables. Overall, 30,427 elderly people aged 60 or above were interviewed. More than a third (35%) of all respondents had participated in the labor force during the seven days preceding the survey. Respondents who were female (OR=0.56), those who were older (OR=0.47 for 70-79 and 0.21 for 80+ years), those who were widowed/divorced (OR=0.85), those who were living with their children (OR=0.69), those whose family income was relatively low, and those who worked in government sectors (OR=0.33) were less likely to participate in the labor force than were their counterparts. On the other hand, those who lived in urban areas (OR=1.2), those who had a low level of education (OR, secondary level 1.8, primary 2.4, and no schooling 2.5), those who were the head of the household (OR=1.9), and those who were in debt (OR=2.3) were more likely be involved in the labor force than their comparison groups. Furthermore, respondents who experienced greater difficulty in daily living, those who suffered from more chronic diseases, and those who assessed their health as poor were less likely to participate in the labor force than their counterparts.

  15. Intercountry comparisons of labor force trends and of related developments: an overview.

    Mincer, J

    1985-01-01

    This paper is a survey of analyses of women's labor force growth in 12 industrialized countries, presented at a conference in Sussex, England in 1983. The main focus is on growth of the labor force of married women from 1960-1980; trends in fertility, wages, and family instability are discussed. In all countries, wages of women were lower than wages of men, although between 1960 and 1980 labor force rates of married women rose in most of the industrialized countries. 2 factors that are associated with this growth are declines in fertility and increases in divorce rates. The 12 countries studied are: 1) Australia, 2) Britain, 3) France, 4) Germany, 5) Israel, 6) Italy, 7) Japan, 8) Netherlands, 9) Spain, 10) Sweden, 11) US, and 12) USSR. The substitution variables (wages of women or their education) have strong positive effects on labor force participation in most cases, and in most cases the positive wage elasticities exceed the negative income elasticities by a sizable margin. A summary table estimating parameters of the P-function for each country, and their predictive performance in time series, are included. From 1960-1980 the average per country growth in participation of married women was 2.84% per year. Wages of working women, in this same period grew, on average, faster than wages of men in most countries, in part due to selectivity by education in labor force growth. While growth rates of real wages across countries have a weak relation with the differential growth rates of married women's labor force, the relation is strong when country parameters are taken into account. The dominance of the "discouraged" over the "added" workers in female labor force growth appears to be upheld internationally. On the average, total fertility rate dropped from 2.42 in 1970 to 1.85 in 1980. Both fertility declines and the growth of family instability appear to represent lagged effects of longer term developments in the labor force of women. Women's wages are lower than

    It has been documented that about 20% of children and adolescents suffer from a diagnosable mental or addictive disorder in the United States. The high prevalence of children's emotional and behavioral problems (EBP) might have a negative effect on their mothers' labor market outcomes because children with EBP require additional time for treatment. However, these children may require additional financial resources, which might promote mothers' labor supply. Previous studies have only considered chronic conditions in analyzing the impact of children's health on parental work activities. Moreover, most of these studies have not accounted for endogeneity in children's health. This article estimates the effects of children's EBP on their mothers' labor supply by family structure while accounting for endogeneity in children's health. We used the 1997 and 2002 Child Development Supplements (CDS) to the Panel Study of Income Dynamics (PSID). We used probit and bivariate probit models to estimate mothers' probability of employment, and tobit and instrumental variable tobit models to estimate the effects of children's EBP on their mothers' work hours. Findings show negative effects of children's EBP on their married mothers' employment and on their single mothers' work hours. © The Author(s) 2014.

    Cross-sectional study of 45- to 64-year-old Australians. To assess the relationship between chronic back problems and being in income poverty among the older working-aged population. Older workers who leave the labor force due to chronic back problems have fragile economic situations and as such are likely to have poorer living standards. Poverty is one way of comparing the living standards of different individuals within society. The 2003 Survey of Disability, Ageing and Carers data were used, along with the 50% of the median equivalized income-unit income poverty line to identify those in poverty. Logistic regression models were used to look at the relationship between chronic back problems, labor force participation, and poverty. Regardless of labor force participation status (employed full-time, part-time, or not in the labor force at all), those with chronic back problems were significantly more likely to be in poverty. Those not in the labor force due to chronic back problems were significantly more likely to be in poverty than those in the labor force full-time with no chronic health condition (Odds ratio [OR]: 0.07, 95% CI: 0.07-0.07, P poverty (OR: 0.52, 95% CI: 0.51-0.53, P poverty than those employed part-time or full-time (OR: 0.44, 95% CI: 0.43-0.44, P < 0.0001; OR: 0.10, 95% CI: 0.10-0.10, P < 0.0001, respectively). This highlights the need to prevent and effectively treat chronic back problems, as these conditions are associated with reduced living standards.

Using the data of the National Survey of Urban Employment for the period 1986-1992, we set, first of all, the evolution of female and male presence in the manufacture of the country's main industrial cities. Further, some of the characteristics of the manufacturing labour force in different types of cities are examined. For this purpose, we are considering several issues: the condition of wage earner and non-wage earner workers, the size of the establishment, some sociodemographic aspects (gender, age, schooling level, and condition of the head of household), as well as different aspects related to labour conditions (length of workday, job benefits, and salary levels)."

    This study analyzed the role of women's labor force participation in relation to binge drinking, smoking and marijuana use among employment age married/cohabiting women. The sample consisted of 956 women who were employed as construction workers (n=104), or were unemployed (n=101), homemakers (n=227) or employed in non-physically demanding occupations (n=524). Results of multivariate logistic regression analyses showed that women construction workers were at elevated risk for smoking and monthly binge drinking; unemployed women were more likely to use marijuana. Women in both categories were at risk for polysubstance use. Additional research is needed to explicate how labor force participation influences women's substance use.

    2007-10-01

    The Intergenerational Report (IGR) released by the Department of the Treasury of the Commonwealth of Australia in 2002 highlighted pressures that in the future would threaten the sustainability of the Australian government's budget balance. These pressures result from the growing needs of an aging population and labor shortages that will limit economic growth and taxation revenue. The IGR has become a driving force in planning government policy. The Treasurer has recently said that "the whole economic agenda of the government at the moment is drawn from the IGR." In response, the Prime Minster and Treasurer have promoted deferred or gradual retirement as part of the solution. However, about 50% of men and 20% of women retire early as a result of ill health, indicating that poor health is potentially a limiter of economic growth. This paper reports lower labor force participation among persons with poorer health and that these persons move out of the labor force at a faster rate as they age. A range of measures suggests some decline in health in the pre-retirement age group (those aged from 40 to 64 years). This indicates that better health may be a facilitator of greater labor force participation in the baby boomer cohort. However, there is evidence that improving economic conditions in Australia leading to low unemployment has created an environment more favorable to the employment of older workers with health problems as there has been a rise in labor force participation in these groups, and measures to prevent chronic disease may further increase the employment prospects.

  9. Labor-force participation patterns of older self-employed workers.

    Science.gov (United States)

    Quinn, J F

    1980-04-01

    Self-employed persons work in a less constrained environment than do most wage-and-salary employees. Generally they are not subject to compulsory retirement nor are they affected by institutional rules concerning labor supply. Data from the 1969 and 1971 interviews of the Retirement History Study show that the labor supply and retirement patterns of the self-employed are distinct from those of other workers. The self-employed (espeically "career" self-employed) nearing retirement age are less likely to be out of the labor force, and those who continue in the labor force have a wider variation in the number of hours worked per year. Downward flexibility in hours (the option for gradual retirement) may be an extremely valuable aspect of self-employed status, and one wonders whether other older workers would also choose this pattern if more flexible opportunities were available. Despite these differences, labor-supply decisions of the self-employed are found to be influenced by many of the same factors that affect the rest of the workforce--health, eligibility for social security and pension benefits, the wage rate, and the flow of asset.

    Full Text Available Background: Maternal labor force participation has increased dramatically over the last 40 years, yet surprisingly little is known about longitudinal patterns of maternal labor force participation in the years after a birth, or how these patterns vary by education. Objective: We document variation by maternal education in mothers' labor force participation (timing, intensity, non-standard work, multiple job-holding over the first nine years after the birth of a child. Methods: We use the Fragile Families and Child Wellbeing Study (N~3000 to predict longitudinal labor force participation in a recent longitudinal sample of mothers who gave birth in large US cities between 1998 and 2000. Families were followed until children were age 9, through 2010. Results: Labor force participation gradually increases in the years after birth for mothers with high school or less education, whereas for mothers with some college or more, participation increases between ages 1 and 3 and then remains mostly stable thereafter. Mothers with less than high school education have the highest rates of unemployment (actively seeking work, which remain high compared with all other education groups, whose unemployment declines over time. Compared with all other education groups, mothers with some college have the highest rates of labor force participation, but Contribution: Simple conceptualizations of labor force participation do not fully capture the dynamics of labor force attachment for mothers in terms of intensity, timing of entry, and type of work hours, as well as differences by maternal education.

In addition, it also has important and strategic role in sup-porting the national economy, primarily as a source of livelihood of millions of rub-ber farmers in rural areas. This study analyzed the potential of using family labor in rubber smallholding sector in Banyuasin Regency, South Sumatra Province, Indo-nesia. The total sample used for the study was 280 respondents of households. Data was analyzed using multiple regression analyses. The multiple regression analysis used to identify the determinants of labor force participation decision regarding work in the rubber smallholding in the study area such as rubber production (kg per year per hectare, number of family workers, age of family head, location of dwelling, education of family head, and average years of schooling of family workers. Based on the analysis, only two factors affected significantly family labor force participation outside their smallholdings, namely number of family labor and education of family head.

We are particularly interested in how the presence in the household of preschool and school-age children and/or the elderly and disabled affects women's likelihood of engaging in work outside the home. We find that the presence of older people in the household (any parent or parent-in-law ...

    1992-01-01

    Most researchers support the notion that a direct negative relationship exists between married women's labor force participation and fertility behavior, yet female employment shows no consistent, general relationship with declining fertility at individual and societal levels. Specific conditions under which employment lowers fertility are therefore explored for the case of Bangladesh. The economic, sociological, and world-system theoretical approaches to the relationship and empirical studies in developing countries including Bangladesh are reviewed. 1975-76 Bangladesh Fertility Survey data on births, deaths, nuptiality, and family planning knowledge and practice for 5772 currently married women of 6513 ever married women under 50 sampled are subjected to multivariate analysis for the study. Analysis revealed that women's modern and traditional occupation as well as higher and secondary education significantly lower their fertility, and that higher age, Islamic religion, use of modern contraceptives, and husband's occupation in transitional and modern sectors have significant positive effects on fertility. The correlation between higher fertility and contraceptive use may be due to women's delay in practicing family planning until reaching desired parity and/or high infant mortality driving women to cease practice in order to replace lost offspring. Future research should be conducted with larger samples and also consider occupations of both husbands and wives. Societal attitudes about women's education should be reformed in support of opening rural schools for women. With 90% of women residing in rural areas and women with traditional occupations having lower fertility, more traditional sector opportunities for women in cottage industry and agriculture production are also recommended, and would help balance skewed urban growth and hypertrophication of the tertiary sector. Finally, motivational efforts should be focused upon encouraging younger instead of older

    Anastasia Gorodzeisky

    Full Text Available The present paper examines modes of immigrants' labor market incorporation into European societies with specific emphasis on the role played by immigrant status (i.e. first-generation immigrants, immigrant descendants and native born without migrant background, region of origin, and gender. The data were obtained from the European Union Labour Forces Survey 2008 Ad-Hoc Module for France, Belgium, UK and Sweden. In order to supplement the results from the country-specific analysis, we replicated the analysis using pooled data from the five rounds of the European Social Survey conducted between 2002 and 2010, for nine 'old immigration' Western European countries together. The analysis centered on two aspects of incorporation: labor force status and occupation. Multinominal, binary logistic as well as linear probability regression models were estimated. The findings suggest that in all countries non-European origin is associated with greater disadvantage in finding employment not only among first-generation immigrants, but also among sons and daughters of immigrants (i.e. second-generation. Moreover, the relative employment disadvantage among immigrant men of non-European origin is especially pronounced in the second-generation. The likelihood of attaining a high-status job is influenced mostly by immigrant status, regardless of region of origin and gender. The results of the study reveal that patterns of labor force incorporation vary considerably across origin groups and across generations. The patterns do not vary as much across countries, despite cross-country differences in welfare state regimes, migration integration policy and composition of migration flows.

    We analyze factors determining women’s decisions to participate in the labor market and provide elderly care and nonfinancial support to their (grand)children. We use data from the Mexican Health and Aging Study, a survey of people aged 50 and over, applying a three-equation, reduced-form SUR model. Results suggest that care needs are the driving force behind caregiving activities. Traditional roles also appear to be relevant in the labor force participation decision: women with a closer labor market connection when they were young are more likely to work. Simulations of demographic changes illustrate potential effects for future caregiving and participation rates. PMID:26924883

    Full Text Available Purpose: The purpose of this study was to summarize safety management of manager into two aspects (design behavior and management behavior and to figure out the different impact these two behaviors might have. Design/methodology/approach: In order to verify the reasonableness of the assumptions, expert investigation was used by the means of semi-structured interview. And the Structural Equation Modeling?SEM? is estimated using 850 individual questionnaire responses from five companies in the form of Likert-type scale. What’s more, taking the measurement error causing by common method biases into consideration, Univariate Testing was taken to measure the deviation effect. Findings: The results obtained with this description showed that certain measures should be adopt by managers to develop purposively the safety knowledge and safety motivation of the skilled labor migrations (SLMs. Research limitations/implications: Unsafe behavior, which has aroused extensive concern in recent years, is the subject of many safety management studies. However, there have not been any studies on the influence of management behavior on SLMs unsafe behavior. Practical implications: As the unsafe behavior of SLMs is the most important accident reason, this paper may help reduce the incidence of accidents. Originality/value: The conclusion of this study will certainly provide the beneficial reference views on the management behavior.

    Full Text Available The foreign direct investments can be considered as one of the main factors that have sustained the evolution of the centralized former communist East-European economies into open competitive market systems. The East-European countries were the destination of some significant capital inflow because of some important features of each market as: development level of the infrastructure, labor force characteristics, market size and its future development possibilities, regulation level of the market, liberalization level of the prices, tax policies and technology absorption capability. When talking about Romania one of the main determinants of the foreign direct investments was the labor force, which attracted in the manufacturing industry to types of investors: cost oriented investors and quality oriented investors. The main goal of this research paper is to provide a clear description of the similarities and of the differences of the two investor types, at national and regional. Data used in this research were collected using a questionnaire and were further analyzed using the SPSS software.

It is noted that this problem has emerged since the early 90s, when these countries got the independence, due to the difficult economic situation, activity of extremist organizations. It is pointed out that the victims of trafficking may be men, women and children, but in most cases they are young women and girls who are sexually exploited. It is shown by the examples of each of the countries of the region, what is being done to counter this terrible phenomenon. The Government of the Republic of Tajikistan established the Interdepartmental Commission to Combat Human Trafficking. The commission, in cooperation with international organizations doing some work to inform the public, the search for victims of sexual business, return and rehabilitation of these persons. In Kazakhstan, according to the new law it has become easier to initiate criminal proceedings concerning labor slavery. In addition, a temporary accommodation center for victims of human trafficking «Komek» was created. In Kyrgyzstan, a working group on the development of 3 of the National Action Plan to Combat Trafficking in Human Beings (2011-2015 under the auspices of the Ministry of Labour, Employment and Migration of the Kyrgyz Republic was created. In Uzbekistan, the law «on combating human trafficking» came into force. In addition, a Republican Interdepartmental Commission to Combat Human Trafficking was created. The law defines the powers of public authorities directly involved in the activities in this direction. In Turkmenistan, the government prohibits all forms of trafficking of persons in accordance with Article 129 of the Criminal Code, adopted in May 2010 and entered into force in July 2010. It provides for penalties ranging from 4 to 25 years in prison. These penalties sufficiently stringent and commensurate with penalties prescribed for other serious crimes, such as rape. At

    The purpose of this study was to determine the effectiveness of BCC approach to the reduction of contracting HIV risk behavior in the construction laborers. Method: This study used operational research design. In this study measures the effectiveness of behavior change of construction workers on the prevention of HIV transmission by comparing the behavior of the construction workers before and after the intervention. The subjects of this study were 150 people risk group of construction workers who work and are spread throughout the city of Surabaya. This research was carried out into three phases, namely, phase preintervention research, intervention research, and post-intervention phase of the study. Implemented in the first year and second year praintervensi stage implemented intervention and post-intervention phases. Result: The results of this study showed that 72% of construction workers is productive (18–35 years and visit his family more than once a month (38%. There is 20% of construction workers had sex with commercial sex workers and no one was using drugs. By 50% of construction workers never get information about HIV/AIDS and as many as 48% never use the services of HIV/AIDS. Discussion: External motivation construction workers associated with the utilization of behavioral HIV/AIDS services with sufficient correlation. Strong external motivation is influenced by risk behaviors of HIV/AIDS were conducted and the desire to get help. Weak external motivation is influenced by a lack of exposure to information related to HIV/AIDS services. The results of the FGD stakeholders have the perception is the same if a construction worker is a high risk group of contracting HIV. Most of the construction workers not have enough knowledge for the prevention of HIV transmission because they do not have access to HIV care and behavior are at risk of contracting HIV by construction workers.

    Full Text Available One of the applications of the prospect theory is the behavioral phenomenon of the negative elasticity of the individual labor supply. This paper argues that the negative elasticity of labor supply can be understood better with the help of the interpretation of the Slutsky equation with regard to the common consumption-leisure choice. The interpretation of the Slutsky equation corresponds to the empirical evidence that leisure is a net complement for an important part of consumption.

    In the present endeavour, force - deflection behavior of various piezoelectric actuator configurations has been analyzed for performance comparison. The response of stack actuator has been simulated using MATLAB Simulink, in a stack actuator-pendulum configuration. During simulation, stack actuator has been used in charge control feedback mode, because of the advantage of low hysteresis, and high linearity. The model incorporates three compensation blocks, viz 1) a PID position controller, 2) a PI piezoelectric current controller, and 3) a dynamic force feedback. A typical stack actuator, having 130 layers, 1.20x10-4 m thickness, 3.46x10-5m2 cross sectional area, of PZT-5H type, has been utilized for simulation. The response of the system has been tested by applying a sinusoidal input of frequency 500 Hz, and waveform amplitude of 1x10-3V.

    What is the factor that affects healthy life expectancy? Healthy life expectancy (HLE) at birth may be influenced by components of the gender inequality index (GII). Notably, this claim is not tested on the between components of the GII, such as population at least secondary education (PLSE) with ages 25 and older, labor force participation rate (LFPR) with ages 15 and older, and the HLE in the world's countries. Thus, this study estimates the associations between the PLSE, LFPR of components of the GII and the HLE. The data for the analysis of HLE in 148 countries were obtained from the World Health Organization. Information regarding the GII indicators for this study was obtained from the United Nations database. Associations between these factors and HLE were assessed using Pearson correlation coefficients and regression models. Although significant negative correlations were found between HLE and the LFPR, positive correlations were found between HLE and PLSE. Finally, the HLE predictors were used to form a model of the components of the GII, with higher PLSE as secondary education and lower LFPR as labor force (R(2) = 0.552, P <0.001). Gender inequality of the attainment secondary education and labor force participation seems to have an important latent effect on healthy life expectancy at birth. Therefore, in populations with high HLE, the gender inequalities in HLE are smaller because of a combination of a larger secondary education advantage and a smaller labor force disadvantage in male-females.

    The aims of this study were (i) to describe the trends in the work environment in 1990-2000 among employees in Denmark and (ii) to establish whether these trends were attributable to labor-force changes. The split-panel design of the Danish Work Environment Cohort Study includes interviews with three cross-sections of 6067, 5454, and 5404 employees aged 18-59 years, each representative of the total Danish labor force in 1990, 1995 and 2000. In the cross-sections, the participation rate decreased over the period (90% in 1990, 80% in 1995, 76% in 2000). The relative differences in participation due to gender, age, and region did not change noticeably. Jobs with decreasing prevalence were clerks, cleaners, textile workers, and military personnel. Jobs with increasing prevalence were academics, computer professionals, and managers. Intense computer use, long workhours, and noise exposure increased. Job insecurity, part-time work, kneeling work posture, low job control, and skin contact with cleaning agents decreased. Labor-force changes fully explained the decline in low job control and skin contact to cleaning agents and half of the increase in long workhours, but not the other work environment changes. The work environment of Danish employees improved from 1990 to 2000, except for increases in long workhours and noise exposure. From a specific work environment intervention point of view, the development has been less encouraging because declines in low job control, as well as skin contact to cleaning agents, were explained by labor-force changes.

    2013-01-01

    Social security for older people in China today has been established institutionally. However, there are substantial problems such as coverage, affordability, fund management, and corruption. This paper aims to provide a general picture of China's social security system for older people and to argue that the inequality of pension arrangements among different segments of the labor force is one of the most conspicuous problems challenging the Chinese government. Four unequal aspects of the pension system concerning the financing resources and pension levels are examined in this paper: (1) unequal institutional arrangements among different sectors, (2) unbalanced governmental expenditure in pension provision, (3) an increasing gap in pension levels between urban and rural areas, and (4) uncovered groups such as the unemployed and self-employed. Historical, economic, and political reasons all contribute to this unequal institution under transition from socialism to a market-oriented economy. At present, it is urgent for the central government to take measures to integrate the various pension arrangements into the unified Old Age Insurance and to reduce the gaps among different regions.

    Perceived work ability refers to a worker's assessment of his or her ability to continue working in his or her job, given characteristics of the job along with his or her resources. Perceived work ability is a critical variable to study in the United States, given an aging workforce, trends to delay retirement, and U.S. policy considerations to delay the age at which full Social Security retirement benefits may be obtained. Based on the job demands-resources model, cognitive appraisal theory of stress, and push/pull factors related to retirement, we proposed and tested a conceptual model of antecedents and outcomes of perceived work ability using 3 independent samples of U.S. working adults. Data regarding workers' job characteristics were from self-report and Occupational Information Network measures. Results from relative importance analysis indicated that health and sense of control were consistently and most strongly related to work ability perceptions relative to other job demands and job and personal resources when perceived work ability was measured concurrently or 2 weeks later in samples with varying occupations. Job demands (along with health and sense of control) were most strongly related to work ability perceptions when perceived work ability was measured in a manufacturing worker sample 1.6 years later. Perceived work ability also predicted lagged labor force outcomes (absence, retirement, and disability leave) while controlling for other known predictors of each. Consistent indirect effects were observed from health status and sense of control to all 3 of these outcomes via perceived work ability. PsycINFO Database Record (c) 2015 APA, all rights reserved.

    The frequent outbreak of environmental threats in China has resulted in increased criticism regarding the health effects of China's urbanization. Urbanization is a double-edged sword with regard to health in China. Although great efforts have been made to investigate the mechanisms through which urbanization influences health, the effect of both economic development and urbanization on health in China is still unclear, and how urbanization-health (or development-health) relationships vary among different income groups remain poorly understood. To bridge these gaps, the present study investigates the impact of both urbanization and economic development on individuals' self-rated health and its underlying mechanisms in China. We use data from the national scale of the 2014 China Labor-force Dynamics Survey to analyze the impact of China's urbanization and economic development on health. A total of 14,791 individuals were sampled from 401 neighborhoods within 124 prefecture-level cities. Multilevel ordered logistic models were applied. Model results showed an inverted U-shaped relationship between individuals' self-rated health and urbanization rates (with a turning point of urbanization rate at 42.0%) and a positive linear relationship between their self-rated health and economic development. Model results also suggested that the urbanization-health relationship was inverted U-shaped for high- and middle-income people (with a turning point of urbanization rate at 0.0% and 49.2%, respectively), and the development-health relationship was inverted U-shaped for high- and low-income people (with turning points of GDP per capita at 93,462 yuan and 71,333 yuan, respectively) and linear for middle-income people. The impact of urbanization and economic development on health in China is complicated. Careful assessments are needed to understand the health impact of China's rapid urbanization.

    Full Text Available Industrialisation is considered as main engine of growth in economic development of the most emerging markets. This is especially true for Central Asian transitional countries as Kazakhstan, which obtained independence from the Soviet Union in 1991. For enhancing country’s competitiveness potential, Kazakhstan National Program for 2010-2014 aimed to accelerate industrial-innovative development of the country. While many papers published about the importance of industrialization activities in Kazakhstan, few have focused on examining the current capacity of labor market to meet the industry demand. Main aim of this paper was to investigate if current manpower is adequate to maintain the planned rate of growth in the country. Higher level of economic production led to higher demand of engineering labor force. High demand with low frequency supply created an imbalance in the labor market that resulted what we see as shortage of technically skilled labor. Low frequency of supply is influenced by such factors as high engineers’ outflow rate, low students enrolment and graduation rates, and lack of practical skills of the graduates hired.

    Population aging in the United States poses challenges to societal institutions while simultaneously creating opportunities to build a more resilient, successful, and cohesive society. Work organization and labor-force participation are central to both the opportunities and challenges posed by our aging society. We argue that expectations about old age have not sufficiently adapted to the reality of aging today. Our institutions need more adaptation in order to successfully face the consequences of demographic change. Although this adaptation needs to focus especially on work patterns among the "younger elderly," our society has to change its general attitudes toward work organization and labor-force participation, which will have implications for education and health care. We also show that work's beneficial effects on well-being in older ages are often neglected, while the idea that older workers displace younger workers is a misconception emerging from the "lump of labor" fallacy. We conclude, therefore, that working at older ages can lead to better quality of life for older people and to a more productive and resilient society overall.

  13. Jobs and the resource curse in the sun: The effects of oil production on female labor force participation in California counties from 1980-2010

    Science.gov (United States)

    Zavala, Gabriel

    This study aims to evaluate the relationship between oil income and the female labor force participation rate in California for the years of 1980, 1990, 2000 and 2010 using panel linear regression models. This study also aims to visualize the spatial patterns of both variables in California through Hot Spot analysis at the county level for the same years. The regression found no sign of a relationship between oil income and female labor force participation rate but did find evidence of a positive relationship between two income control variables and the female labor force participation rate. The hot spot analysis also found that female labor force participation cold spots are not spatially correlated with oil production hot spots. These findings contribute new methodologies at a finer scale to the very nuanced discussion of the resource curse in the United States.

Se realizó una encuesta a una muestra de 60 trabajadores para determinar fundamentalmente el nivel de satisfacción de estos hacia la entidad.Se emplearon los métodos de Análisis y Síntesis, Monográfico, Observación y el Horizontal y Vertical. Sus principales resultados muestran que la causa con mayor incidencia en la fluctuación laboral fue la mejora salarial en un 58 % y la categoría ocupacional más afectada fue la de obreros, representando un 96 % del total. Resultó ser el poco incentivo motivacional y financiero lo que originó que la fuerza laboral que trabaja fundamentalmente vinculada a las actividades agrícolas fluctuara en el período analizado. ABSTRACT The behavior of the fluctuation of the labor force in sugarcane "Siboney" Basic Unit of Cooperative Production (UBPC was assessed. The reasons for labor and occupational fluctuation fluctuating positions are determined. A survey of a sample of 60 employees was used to fundamentally determine the level of satisfaction of these to the entity. Methods of Analysis and Synthesis, Monograph, Observation and Horizontal and Vertical are used. The main results show that the cause with the greatest impact on wage labor fluctuation was improved by 58% and the most affected was the occupational category of workers, representing 96% of the total. It turned out to be little financial incentive motivational and which meant that the labor force working fluctuate mainly linked to agricultural activities in the period.

    Full Text Available The analysis of the propensity to search specifies the “common” or the ordinary model of consumer behavior based on the synthesis of the neoclassical approach with satisficing concept, and “leisure” and “labor” models of behavior that represent different combinations of conspicuous consumption, leisure, and labor. While the “common model” of behavior demonstrates a moderate propensity to search, “leisure” and “labor” models of consumer behavior exhibit vigorous propensities to search that results in purchase of unnecessary items and therefore in overconsumption. This trend is also presented in home production where vigorous propensity to search takes the form of the vigorous propensity to produce at home. The analysis of trends in allocation of time provides grounds for the assumption that men have more accentuated propensity to search and to produce at home than women that results in overconsumption of unnecessary items.

    Background Although the dire life circumstances of labor migrants working in Russia are well-known, their HIV risk vulnerability and prevention needs are understudied. Low socioeconomic status, lack of access to services, separation from family, and limited risk awareness all contribute to migrants’ HIV vulnerability. Methods Male labor migrants in St. Petersburg (n=499) were administered assessments of their sexual behavior practices, substance use, and psychosocial characteristics related to risk and well-being. Results Thirty percent of migrants reported multiple female partners in the past 3 months. Condom use was low, ranging from 35% with permanent to 52% with casual partners. Central Asian migrants had very low AIDS knowledge, low levels of substance use, moderate sexual risk, high depression, and poor social supports. Eastern European migrants had higher AIDS knowledge, alcohol and drug use, and sexual risk. Discussion Improved HIV prevention efforts are needed to reduce the risk vulnerability of migrants who relocate to high disease prevalence areas. PMID:20690041

    Full Text Available It has been documented that about 20% of children and adolescents suffer from a diagnosable mental or addictive disorder in the United States. The high prevalence of children’s emotional and behavioral problems (EBP might have a negative effect on their mothers’ labor market outcomes because children with EBP require additional time for treatment. However, these children may require additional financial resources, which might promote mothers’ labor supply. Previous studies have only considered chronic conditions in analyzing the impact of children’s health on parental work activities. Moreover, most of these studies have not accounted for endogeneity in children’s health. This article estimates the effects of children’s EBP on their mothers’ labor supply by family structure while accounting for endogeneity in children’s health. We used the 1997 and 2002 Child Development Supplements (CDS to the Panel Study of Income Dynamics (PSID. We used probit and bivariate probit models to estimate mothers’ probability of employment, and tobit and instrumental variable tobit models to estimate the effects of children’s EBP on their mothers’ work hours. Findings show negative effects of children’s EBP on their married mothers’ employment and on their single mothers’ work hours.

  20. Implications of behavioral architecture for the evolution of self-organized division of labor.

    Full Text Available Division of labor has been studied separately from a proximate self-organization and an ultimate evolutionary perspective. We aim to bring together these two perspectives. So far this has been done by choosing a behavioral mechanism a priori and considering the evolution of the properties of this mechanism. Here we use artificial neural networks to allow for a more open architecture. We study whether emergent division of labor can evolve in two different network architectures; a simple feedforward network, and a more complex network that includes the possibility of self-feedback from previous experiences. We focus on two aspects of division of labor; worker specialization and the ratio of work performed for each task. Colony fitness is maximized by both reducing idleness and achieving a predefined optimal work ratio. Our results indicate that architectural constraints play an important role for the outcome of evolution. With the simplest network, only genetically determined specialization is possible. This imposes several limitations on worker specialization. Moreover, in order to minimize idleness, networks evolve a biased work ratio, even when an unbiased work ratio would be optimal. By adding self-feedback to the network we increase the network's flexibility and worker specialization evolves under a wider parameter range. Optimal work ratios are more easily achieved with the self-feedback network, but still provide a challenge when combined with worker specialization.

    The major features of insect societies that fascinate biologists are the self-sacrificing altruism expressed by colony members, the complex division of labor, and the tremendous plasticity demonstrated in the face of changing environments. The social behavior of insects is a result of complex interactions at different levels of biological organization. Genes give rise to proteins and peptides that build the nervous and muscular systems, regulate their own synthesis, interact with each other, and affect the behavior of individuals. Social behavior emerges from the complex interactions of individuals that are themselves far removed from the direct effects of the genes. In order to understand how social organization evolves, we must understand the mechanisms that link the different levels of organization. In this review, we discuss how behavior is influenced by genes and the neural system and how social behavior emerges from the behavioral activities of individuals. We show how different levels of organization share common features and are linked through common mechanisms. We focus on the behavior of the honey bee, the best studied of all social insects.

    Abstract Introduction Past research suggests a link between post‐traumatic stress disorder (PTSD) and an increased risk for sexual problems. However, there is still no clear picture whether these higher rates are related to trauma exposure or to PTSD itself. Aim The aim of the present study was to complement existing knowledge on the relative impact of trauma and PTSD on sexuality in later life, considering different aspects of trauma exposure on both men and women. Methods The study was conducted on a unique population sample of former Swiss indentured child laborers (55 men, M age 78, age range 60–95 years) who have repeatedly experienced a variety of severe childhood traumas. Main Outcome Measures Sexual outcomes were measured using two scales from the Trauma Symptom Inventory—Dysfunctional Sexual Behavior (DSB) and Sexual Concerns (SC). PTSD symptoms and trauma were assessed with the Short Screening Scale for PTSD and the Composite International Diagnostic Interview, respectively. Results Twenty‐two individuals showed PTSD symptoms, and 53 reported having experienced childhood trauma. Significant differences between men and women were reported for DSB and SC. Men reported a significantly higher prevalence of both SC and DSB compared with women. Conclusions This is the very first study investigating DSB and SC in a sample of older adults exposed to similar traumatic experiences and settings. However, some study limitations need to be considered such as the small sample size. Additional studies are needed to further explore the relative role of traumatization and PTSD on sexual behavior and well‐being, especially to improve sexual therapy for patients who experience trauma.

    Full Text Available The labor market is an important component of the entire economic system and for social-economic development. However, the labor market is known as the most inflexible of markets, the existence of the phenomenon of permanent labor mobility. After 1990, the Romanian society has experienced a series of economic and social transformation, new reforms covering all areas of activity. Increasing labor resources was accompanied by a continued reduction in employment and increase in unemployment. The government tried to initiate programs, including external funding to create jobs, but compared to the massive layoffs that occurred following the restructuring of sectors, the number of new jobs created has proved insufficient. The paper presents a multiple regression model for employment and prognosis for this until 2020.

  7. Work-Family Conflict: The Effects of Religious Context on Married Women’s Participation in the Labor Force

    Full Text Available Past work shows religion’s effect on women’s career decisions, particularly when these decisions involve work-family conflict. This study argues that the religious context of a geographic area also influences women’s solutions to work-family conflict through more or less pervasive normative expectations within the community regarding women’s roles and responsibilities to the family. We use the American Community Survey linked with community-level religious proportions to test the relationship between religious contexts and women’s participation in the labor force in the contiguous United States–2054 census geographic areas. Using spatial analysis, we find that community religious concentration is related to the proportion of women who choose not to work. Communities with a higher proportion of the population belonging to conservative religious traditions also have a greater proportion of married women choosing not to work outside the home.

  8. Economic Growth, Electricity Consumption, Labor Force and Capital Input: A More Comprehensive Analysis on North China Using Panel Data

    Full Text Available Over the past three decades, China’s economy has witnessed remarkable growth, with an average annual growth rate over 9%. However, China also faces great challenges to balance this spectacular economic growth and continuously increasing energy use like many other economies in the world. With the aim of designing effective energy and environmental policies, policymakers are required to master the relationship between energy consumption and economic growth. Therefore, in the case of North China, a multivariate model employing panel data analysis method based on the Cobb-Douglas production function which introduces electricity consumption as a main factor was established in this paper. The equilibrium relationship and causal relationship between real GDP, electricity consumption, total investment in fixed assets, and the employment were explored using data during the period of 1995–2014 for six provinces in North China, including Beijing City, Tianjin City, Hebei Province, Shanxi Province, Shandong Province and Inner Mongolia. The results of panel co-integration tests clearly state that all variables are co-integrated in the long term. Finally, Granger causality tests were used to examine the causal relationship between economic growth, electricity consumption, labor force and capital. From the Granger causality test results, we can draw the conclusions that: (1 There exist bi-directional causal relationships between electricity consumption and real GDP in six provinces except Hebei; and (2 there is a bi-directional relationship between capital input and economic growth and between labor force input and economic growth except Beijing and Hebei. Therefore, the ways to solve the contradiction of economic growth and energy consumption in North China are to reduce fossil energy consumption, develop renewable and sustainable energy sources, improve energy efficiency, and increase the proportion of the third industry, especially the sectors which

    The aim of this study was to investigate the effect of ill health and socioeconomic status on labor force exit due to unemployment, early retirement, disability pension, or becoming economically inactive. A secondary objective was to investigate the effect of ill health and socioeconomic status on return to work. A representative sample of the Dutch working population (N=15 152) was selected for a prospective study with ten years follow-up (93 917 person-years). Perceived health and individual and household characteristics were measured at baseline with the Permanent Quality of Life Survey (POLS) during 1999-2002. Statistics Netherlands ascertained employment status monthly from January 1999 to December 2008. Cox proportional hazards analyses were used to determine the factors that predicted labor force exit and return to work. Ill health increased the likelihood of labor force exit into unemployment [hazard ratio (HR) 1.89], disability pension (HR 6.39), and early retirement (HR 1.20), but was not a determinant of becoming economically inactive (HR 1.07). Workers with low socioeconomic status were, even after adjusting for ill health, more likely to leave the labor force due to unemployment, disability pension, and economic inactivity. Workers with ill health at baseline were less likely to return to work after unemployment (HR 0.75) or disability pension (HR 0.62). Socioeconomic status did not influence re-employment. Ill health is an important determinant for entering and maintaining paid employment. Workers with lower education were at increased risk for health-based selection out of paid employment. Policies to improve labor force participation, especially among low socioeconomic level workers, should protect workers with health problems against exclusion from the labor force.

    Tay, Louis; Harter, James K

    2013-07-01

    In light of recent interest in societal subjective well-being, policies that seek to improve the economy and labor markets need to address the question of whether economic factors matter for worker well-being, specifically job satisfaction. In a worldwide representative poll of 136 nations, economic factors are associated with job satisfaction beyond demographic and job factors. Hierarchical linear modeling showed that higher national GDP and job optimism was associated with job satisfaction, whereas higher unemployment was associated with job dissatisfaction. Mediational analyses revealed that economic variables (GDP and job optimism) were partially mediated by job satisfaction in predicting life satisfaction; full mediation was found for unemployment. In a second study, time series regression of monthly data from a nationally representative poll in the United States from 2008 to 2011 revealed that unemployment rate was significantly associated with job dissatisfaction over time. There was some evidence that prior unemployment rates predicted job satisfaction at a higher level than job satisfaction predicted unemployment rates, suggesting that economic factors lead to job (dis)satisfaction rather than the converse. Theoretical and practical implications are discussed. © 2013 The Authors. Applied Psychology: Health and Well-Being © 2013 The International Association of Applied Psychology.

    2015-01-01

    This study examined the association between emotional labor and organizational citizenship behavior (OCB) and the mediation of work engagement in this relationship. A total of 264 teachers in Mainland China were recruited for this study. Bivariate correlation showed that both deep acting and the expression of naturally felt emotion were positively related to the two dimensions of OCB, namely, OCB toward the individual (OCBI) and OCB toward the organization (OCBO), whereas surface acting was not related to the OCB dimensions. Work engagement was also positively associated with both OCB dimensions. Regression results showed that work engagement partially mediated the relation between deep acting and OCBO, and that between the expression of naturally felt emotion and OCBI. Work engagement also fully mediated the association between deep acting and OCBI, and that between the expression of naturally felt emotion and OCBO. In light of these findings, strategies that encourage employees to display emotions consistent with their inner experience were discussed.

    Full Text Available The objective of this paper is to present an empirical study of the behavior of labor industrial productivity in the regions of Brazil during the period 1996 to 2010 by groups of technology intensity. It was used the shift-share method. The results indicated that in the groups of sectors that showed positive growth rates were the competitive advantages inherent to each region that explained, in most cases, the growth of labor productivity. There was predominance of technology absorbing sectors in prejudice of sectors that generate technological spillovers. The growth of labor productivity in the extractive industry showed a upward trend, while the manufacturing industry showed downward trend, evidencing a stagnation of labor productivity at the national level. There are evidences of a reprimarization process of industrial activities through the specialization in commodities.

    "In this paper the author presents a study of the spatial mobility of the Quebec population between 1966 and 1976, in the light of regional capitalist development. Based on an empirical operationalization of the concepts of mobility and development, the author demonstrates that Quebec presents a very irregular distribution of its poles of development over its territory, and that the mobility of the work force is in the image of this distribution. A few regions within the Montreal metropolitan area have attained a relatively evolved state of capitalist development and consequently are able to attract within their limits a large majority of migrants moving inside of or toward Quebec. In contrast, it can be observed that the majority of the regions in Quebec may be qualified as 'underdeveloped', and that their net mobility figures are negative." (SUMMARY IN ENG AND SPA) excerpt

    2010-06-01

    Efforts to retain nurses within the profession are critical for resolving the global nursing shortage, but very little research explores the phenomenon of nursing workforce attrition in the U.S. This study is the first to simultaneously investigate the timing of attrition through survival analysis, the exit path taken (career change vs. labor force separation), and the major socioeconomic, family structure, and demographic variables predicting attrition in this country. Using nationally representative U.S. data from the 2004 National Sample Survey of Registered Nurses (N=29,472), we find that the rate of labor force separation is highest after the age of 60, a typical pattern for retirement. However, a non-trivial proportion of career change also occurs at older ages (50+ years old), and the rate of labor force separation begins to climb at relatively young ages (30-40 years old). Particularly strong predictors of early labor force separation include being married and providing care to dependents in the home (young children or elderly parents). Career change is predicted strongly by higher levels of education, male gender, and current enrollment in a non-nursing degree program. Having an Advanced Practice credential reduced the hazards of attrition for both exit paths. The results suggest a fruitful path for future research and a number of policy approaches to curbing nurse workforce attrition. Copyright 2010 Elsevier Ltd. All rights reserved.

    This paper examines the links between risky health behaviors and labor market success. We provide new evidence on the joint relationships between the most prominent forms of risky health behavior - alcohol consumption, smoking and physical inactivity - and long-term labor market outcomes. We use twin data for Finnish men and women linked to register-based individual information on earnings and labor market attachment. The twin data allow us to account for shared family and environmental factors and to measure risky health behaviors in 1975 and 1981. The long-term labor market outcomes were measured in adulthood as an average over the period 1990-2009. The sample sizes are 2156 and 2498 twins, for men and women, respectively. We find that being both a smoker and a heavy drinker in early adulthood is negatively related to long-term earnings and employment later in life, especially for men. We conclude that how and why risky health behaviors cluster and how that affects individual level outcomes call for more attention. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Full Text Available HIV transmission in rural areas of China is being fueled in part by migrant workers who acquire HIV outside of their hometowns. Recent surveillance statistics indicate that HIV prevalence among returning migrants has increased significantly.We conducted a community-based cross-sectional study to assess HIV-related knowledge, attitudes and behaviors among migrant returnees in Nantong, Jiangsu Province, one of the largest exporters of migrant laborers.A total of 1625 subjects were enrolled with a response rate of 89%. All participants were male and of the majority Han ethnicity. The mean age was 39.0 years (SD = 6.7; range: 18 to 63, and most had a stable partner (N = 1533, 94.3%. Most correctly identified the major modes of HIV transmission (68.9%-82.0%, but fewer were able to identify ways that HIV cannot be transmitted. Nearly one-third of participants held positive attitudes toward having multiple sex partners, and nearly half believed that sex work should be legalized. Multiple logistic regression analysis indicated that risky sexual behavior (defined as sex with a casual or commercial sex partner was associated with no stable partner; working abroad; correct condom use; age <22 at first sex; higher coital frequency; and having a positive attitude towards multiple sex partners.We found high levels of reported sex with a casual or commercial sex partner and low levels of consistent condom use. HIV prevention interventions among migrant workers need to focus on younger migrants, migrants without stable partners, and migrants who travel abroad for work.

    Full Text Available El objetivo principal de este texto es discutir la aplicación de la noción de "fuerza de trabajo secundaria" para caracterizar la fuerza da trabajo femenina en América Latina. Esa caracterización, hecha con frecuencia en forma mecánica por un lado corresponde, cada vez menos a la realidad de los hechos, ya que es creciente la participación femenina en el mercado de trabajo, así como la continuidad de sus trayectorias laborales, el número de horas dedicadas al trabajo remunerado, así como su aporte al ingreso familiar y a la superación de la situación de pobreza de un porcentaje importante de hogares. Por otro lado, el texto argumenta que esa caracterización es uno de los elementos centrales en la estructuración de los patrones de discriminación de género que persisten y se reproducen en el mercado de trabajo latinoamericano.This article aims to discuss the concept of "secondary labor force" to characterize female workforce in Latin America. Such characterization corresponds increasingly less to reality, as women's participation in the labor force and the hours dedicated to their paid work continues to grow, as well as their contribution to household income. The article argues that such characterization is one of the core elements of the gender discriminating patterns that persist in Latin American labor market.

  3. An empirical investigation of female labor-force participation, fertility, age at marriage, and wages in Korea.

    1985-07-01

    The Korean experience raises questions about the assumption that successful economic development and equitable income distribution are preconditions for rapid fertility declines. During the 1960-70 decade, the total fertility rate in Korea declined by 36% and the crude birth rate fell by 33%, in the absence of significant economic development. This paper uses data from the 1974 Korean Fertility Survey to explore the relationships between the factors responsible for this rapid fertility decline. A simultaneous equation model of fertility, age at marriage, extent of labor force participation during marriage, quality of children, and wages is developed and tested. Rather than to provide definitive measures of these interrelationships, the aim was to investigate the utility of treating several variables as being jointly determined. The results suggest that parental education affects fertility by influencing age at marriage, implying that adult education programs will have little effect on marital fertility. There was some evidence that working women whose jobs are compatible with child care have more children than nonworking women, a finding that should be considered in planning increased job opportunities for women. Urbanized women and those who work before marriage tend to marry later than their less urbanized counterparts or women who do not work prior to marriage. Finally, women who used modern methods of birth control had significantly lower fertility than nonusers of modern methods. There is concern that the Government has reduced budgetary appropriations to family planning since the goal of reducing the annual population growth rate from 3% in 1960 to 2% in 1970 was achieved. It is suggested that family planning expenditures should be deployed to areas such as urban slums that have not yet been reached by family planning programs.

    Full Text Available BACKGROUND: Around 41% of Human Immunodeficiency Virus (HIV cases in Nepal occur in seasonal migrant laborers. Dalit migrant laborers represent the largest proportion of reported HIV cases in the Far Western Region (Sudur Pashchimanchal, or Far West, Nepal. The study's objectives were to assess sexual behavior, condom use status and HIV risk perception among Dalit migrant laborers to India from Far West Region, Nepal. METHODS: The study was conducted among Dalit male migrant laborers aged 15 years and above who had migrated for at least six months of the last two years to India. For the sampling the village development committees (VDCs from Achham, Doti and Kanchanpur districts of Nepal were purposively selected. The data were collected in March and April 2011 via ten in-depth interviews and four focus group discussions and analyzed using content analysis. RESULTS: Poor socio-economic status, caste-related discrimination, and lack of employment opportunities push large groups of young Dalits to migrate to India for employment, where they engage in sex with female sex workers (FSWs. The participants described unmarried status, peer influence, alcohol use, low-priced sex with FSWs and unwillingness to use condoms as common factors of their migration experience. Lack of awareness on HIV/AIDS was common among study participants. Awareness of HIV/AIDS and faithful, monogamous partnerships are reported as factors influencing safer sexual behavior. CONCLUSIONS: Dalits are an especially vulnerable population among migrant laborers and may be over-represented in new HIV infections in Nepal. Comprehensive surveying and health promotion programs targeted to this population are urgently needed and potent methods of stopping HIV spread.

  10. Division of labor regulates precision rescue behavior in sand-dwelling Cataglyphis cursor ants: to give is to receive.

    Directory of Open Access Journals (Sweden)

    Elise Nowbahari

    Full Text Available Division of labor, an adaptation in which individuals specialize in performing tasks necessary to the colony, such as nest defense and foraging, is believed key to eusocial insects' remarkable ecological success. Here we report, for the first time, a completely novel specialization in a eusocial insect, namely the ability of Cataglyphis cursor ants to rescue a trapped nestmate using precisely targeted behavior. Labeled "precision rescue", this behavior involves the ability of rescuers not only to detect what, exactly, holds the victim in place, but also to direct specific actions to this obstacle. Individual ants, sampled from each of C. cursor's three castes, namely foragers, nurses and inactives, were experimentally ensnared (the "victim" and exposed to a caste-specific group of potential "rescuers." The data reveal that foragers were able to administer, and obtain, the most help while members of the youngest, inactive caste not only failed to respond to victims, but also received virtually no help from potential rescuers, regardless of caste. Nurses performed intermediate levels of aid, mirroring their intermediate caste status. Our results demonstrate that division of labor, which controls foraging, defense and brood care in C. cursor, also regulates a newly discovered behavior in this species, namely a sophisticated form of rescue, a highly adaptive specialization that is finely tuned to a caste member's probability of becoming, or encountering, a victim in need of rescue.

    The forced swim test (FST) is a behavioral test in rodents which was developed in 1978 by Porsolt and colleagues as a model for predicting the clinical efficacy of antidepressant drugs. A modified version of the FST added the classification of active behaviors into swimming and climbing, in order to facilitate the differentiation between serotonergic and noradrenergic classes of antidepressant drugs. The FST is now widely used in basic research and the pharmaceutical screening of potential antidepressant treatments. It is also one of the most commonly used tests to assess depressive-like behavior in animal models. Despite the simplicity and sensitivity of the FST procedure, important differences even in baseline immobility rates have been reported between different groups, which complicate the comparison of results across studies. In spite of several methodological papers and reviews published on the FST, the need still exists for clarification of factors which can influence the procedure. While most recent reviews have focused on antidepressant effects observed with the FST, this one considers the methodological aspects of the procedure, aiming to summarize issues beyond antidepressant action in the FST. The previously published literature is analyzed for factors which are known to influence animal behavior in the FST. These include biological factors, such as strain, age, body weight, gender and individual differences between animals; influence of preconditioning before the FST: handling, social isolation or enriched environment, food manipulations, various kinds of stress, endocrine manipulations and surgery; schedule and routes of treatment, dosage and type of the drugs as well as experimental design and laboratory environmental effects. Consideration of these factors in planning experiments may result in more consistent FST results. PMID:23685235

    2009-12-01

    Full Text Available This article makes use of ARFIMA models and unit root tests with structural breaks to examine the unemployment persistence of different labor forces in the Greater Metropolitan Area of São Paulo. To this purpose, not only is the region's open unemployment rate analyzed but it is also disaggregated by gender, age, color and position within the household. The period ranges from January 1985 to November 2008 and, despite using a range of estimation methods, the presence of a unit root cannot be rejected in general. The exceptions are the series related to Age 15-17 and over 40. But even in these cases the parameter "d" lies above 0.5. This is an indication that the unemployment rates in São Paulo can be defined as non stationary and the majority of the series are not mean-reverting. Therefore, the disinflation policies implemented by the Brazilian policymakers in the last two decades, as well as changes in real variables, have had long-lasting effects on the unemployment rates in São Paulo.Este artigo usa modelos ARFIMA e testes de raiz unitária com quebra estrutural para examinar o grau de persistência do desemprego de diferentes estratos da força de trabalho na Região Metropolitana de São Paulo. Para tanto, a taxa agregada desta região é examinada, como também sua desagregação por gênero, idade, raça e posição dentro da família. O período de análise vai de janeiro de 1985 a novembro 2008 e, apesar do uso de diferentes métodos de estimação, a hipótese de raiz unitária não é rejeitada em geral. As duas exceções são as séries relacionadas aos trabalhadores entre 15 e 17 anos e acima dos 40 anos. Mas, mesmo nestes dois casos, o parâmetro "d" fica acima de 0,5.

    Objective: To estimate the impact of risk factors control on non-communicable diseases (NCDs) mortality, life expectancy and the numbers of labor force lost in China in 2030. Methods: We used the results of China from Global Burden of Disease Study 2013, according to the correlation between death of NCDs and exposure of risk factors and the comparative risk assessment theory, to calculate population attributable fraction (PAF) and disaggregate deaths of NCDs into parts attributable and un-attributable. We used proportional change model to project risk factors exposure and un-attributable deaths of NCDs in 2030, then to get deaths of NCDs in 2030. Simulated scenarios according to the goals of global main NCDs risk factors control proposed by WHO were constructed to calculate the impact of risk factors control on NCDs death, life expectancy and the numbers of labor force lost. Results: If the risk factors exposure changed according to the trend of 1990 to 2013, compared to the numbers (8.499 million) and mortality rate (613.5/100 000) of NCDs in 2013, the death number (12.161 million) and mortality rate (859.2/100 000) would increase by 43.1% and 40.0% respectively in 2030, among which, ischemic stroke (increasing by 103.3% for death number and 98.8% for mortality rate) and ischemic heart disease (increasing by 85.0% for death number and 81.0% for mortality rate) would increase most quickly. If the risk factors get the goals in 2030, the NCDs deaths would reduce 2 631 thousands. If only one risk factor gets the goal, blood pressure (1 484 thousands NCDs deaths reduction), smoking (717 thousands reduction) and BMI (274 thousands reduction) would be the most important factors affecting NCDs death. Blood pressure control would have greater impact on ischemic heart disease (662 thousands reduction) and hemorrhagic stroke (449 thousands reduction). Smoking control would have the greatest effect on lung cancer (251 thousands reduction) and chronic obstructive pulmonary

    Inequalities in demographic, socio-economic and health status for China labor force place them at greater health risks, and marginalized them in the utilization of healthcare services. This paper identifies the inequalities which limit the utilization of health services among China labor force, and provides a reference point for health policy. Data were collected from 23,505 participants aged 15 to 65, from the 2014 China Labor Force Dynamic Survey (a nationwide cross-sectional survey covering 29 provinces with a multi-stage cluster, and stratified, probability sampling strategy) conducted by Sun Yat-sen University. Logistic regression models were used to study the effects of demographic (age, gender, marital status, type of hukou and migration status), socio-economic (education, social class and insurance) and health status (self-perceived general health and several chronic illnesses) variables on the utilization of health services (two-week visiting and hospitalization during the past 12 months). Goodness of fit was assessed using Hosmer-Lemeshow test. Discrimination ability was assessed based on the area under the receiver operating curve (AUC). Migrants with more than 1 (OR 2.80, 95% CI 1.01 ~ 7.82) or none chronic illnesses (OR 1.26, 95% CI 1.01 ~ 7.82) are more likely to be two week visiting to the clinic than non-migrants; migrants with none chronic illnesses (OR 0.61, 95% CI 0.45 ~ 0.82) are less likely to be in hospitalization during the past 12 months than non-migrants. Female, elder, hukou of non-agriculture, higher education level, higher social class, purchasing more insurance and poorer self-perceived health were predictors for more utilization of health service. More insurance benefited more two-week visiting (OR 1.12, 95% CI 1.06 ~ 1.17) and hospitalization during the past 12 months (OR 1.12, 95% CI 1.07 ~ 1.18) for individuals with none chronic illness but not ≥1 chronic illnesses. All models achieved good calibration

    On a more general level, the results of the study suggest that market-oriented economic reform brought about diverse effects on Chinese women in terms of labor market status. Though the institutional barriers put Chinese female rural workers in a position of disadvantage, the performance of female rural-urban migrant workers suggests that they are active beings rather than passive victims merely adapting to the social transformation. Female rural-urban migrant workers have been and still are playing important and speci? c roles at the crossover between the emerging capitalist economy and the traditional rural society. In doing so they are positive participants of globalization in a wider development perspective.

    Condensation characteristics of vapor bubble after the departure from a heated section in forced convective subcooled flow boiling were studied visually by using a high speed camera. The purpose of the present study was to measure two-phase flow parameters in subcooled flow boiling. These two-phase flow parameters are void fraction, interfacial area concentration and Sauter mean diameter, which express bubble interface behaviors. The experimental set-up was designed to measure the two-phase flow parameters necessary for developing composite equations for the two fluid models in subcooled flow boiling. In the present experiments, the mass flux, liquid subcooling and the heater were varied within 100-1000kg/m 2 s, 2-10K and 100-300kW/m 2 respectively. Under these experimental conditions, the bubble images were obtained by a high-speed camera, and analyzed paying attention to the condensation of vapor bubbles. These two-phase parameters were obtained by the experimental data, such as the bubble parameter, the bubble volume and the bubble surface. In the calculation process of the two phase flow parameters, it was confirmed that these parameters are related to the void fraction. (author)

    Full Text Available Latino Day Laborers (LDLs are employed in occupations where multiple work hazards exist. One such hazard is the overexposure to solar ultraviolet radiation for continuous periods of time. Regular sun exposure can put individuals at increased risk of developing skin cancers, especially without adequate protection. The purpose of this cross-sectional exploratory study was to use a social cognitive framework to assess skin protective behaviors among LDLs. A community-based nonrandom and purposive sample of LDLs was recruited in two states: Mississippi and Illinois. The study sample consisted of 137 male participants, of which the majority were of Mexican ancestry (72%. The average age was 35.40 (SD=9.89 years. Results demonstrated that a substantial number of LDLs do not adequately practice sun protection behaviors on a regular basis. The skin cancer knowledge scores were very modest. The most frequently indicated barriers towards sun protection were “inconvenient,” “forget to use,” and “not being able to reapply sunscreen.” Overall, LDLs had moderate confidence in their abilities to adopt successful sun protection strategies. This study underscores the need for intervention programs aimed at LDLs to reduce extended time in the sun and increase use of sun protective measures when working outdoors.

    Few issues in developing countries draw as much popular attention as child labor. This paper begins by quantifying the extent and main characteristics of child labor. It then considers the evidence on a range of issues about child labor. Fundamentally, child labor is a symptom of poverty. Low income and poor institutions are driving forces behind the prevalence of child labor worldwide. This study concludes by assessing the policy options to reduce worldwide child labor.

  9. The role of response force on the persistence and structure of behavior during extinction.

    Behavior Momentum Theory has emerged as a prominent account of resistance to change in both basic and applied research. Although laboratory studies often define precise, repeatable responses, application research often deals with response classes that may vary widely along a number of dimensions. In general, Behavior Momentum Theory has not addressed how response dimensions impact resistance to change, providing an opportunity to expand the model in new directions. Four rats pressed a force transducer under a multiple variable interval (VI) 60-s VI 60-s schedule of reinforcement. In one component, responses satisfied the schedule only if the response force fell within a "low" force band requirement; responses in the other schedule were required to satisfy a "high" force band. Once responding stabilized, extinction was programmed for three sessions. Then, the procedures were replicated. The results showed that response force came under discriminative control, but force requirements had no impact on resistance to extinction. In a follow-up condition, the schedule was changed to a multiple VI 30-s VI 120-s schedule and the low-force band operated in both components. The results showed that behavior maintained by the VI 30-s schedule was generally more resistant to extinction. A secondary analysis showed that force distributions created under baseline maintained during extinction. Overall, the results suggest that differential response force requirements prevailing in steady state do not affect the course of extinction. © 2018 Society for the Experimental Analysis of Behavior.

    2013-01-01

    The force-dependent tunneling transport in metal/alkanethiol/metal junctions was examined using CAFM. Tunneling current and current density through alkanethiol SAMs increased with increasing tip-loading force in CAFM, which suggests that a potential change in geometry of the molecules under the tip loads influences the transport properties of alkanethiol SAMs. Enhanced intermolecular tunneling transport in the tilted molecular configuration under tip-loading effect is likely responsible for such an increase in tunneling current density. We also demonstrated that through-bond tunneling is a more efficient pathway in alkanethiol SAMs than are intermolecular chain-to-chain pathways, by demonstrating a dependence of current density on the associated tunneling distances. We report a tip-loading, force-dependent tunneling behavior in alkanethiol SAMs using CAFM. A variable tip-loading force applies to alkanethiol SAMs with a standard AFM feedback, and current(I)-voltage(V) characteristics are simultaneously measured while varying the loading forces. In particular, we observe how a tip-loading force in CAFM influences the transport properties of alkanethiol SAMs

  13. Force-extension behavior of DNA in the presence of DNA-bending nucleoid associated proteins

    Dahlke, K.; Sing, C. E.

    2018-02-01

    Interactions between nucleoid associated proteins (NAPs) and DNA affect DNA polymer conformation, leading to phenomena such as concentration dependent force-extension behavior. These effects, in turn, also impact the local binding behavior of the protein, such as high forces causing proteins to unbind, or proteins binding favorably to locally bent DNA. We develop a coarse-grained NAP-DNA simulation model that incorporates both force- and concentration-dependent behaviors, in order to study the interplay between NAP binding and DNA conformation. This model system includes multi-state protein binding and unbinding, motivated by prior work, but is now dependent on the local structure of the DNA, which is related to external forces acting on the DNA strand. We observe the expected qualitative binding behavior, where more proteins are bound at lower forces than at higher forces. Our model also includes NAP-induced DNA bending, which affects DNA elasticity. We see semi-quantitative matching of our simulated force-extension behavior to the reported experimental data. By using a coarse-grained simulation, we are also able to look at non-equilibrium behaviors, such as dynamic extension of a DNA strand. We stretch a DNA strand at different rates and at different NAP concentrations to observe how the time scales of the system (such as pulling time and unbinding time) work in concert. When these time scales are similar, we observe measurable rate-dependent changes in the system, which include the number of proteins bound and the force required to extend the DNA molecule. This suggests that the relative time scales of different dynamic processes play an important role in the behavior of NAP-DNA systems.

    Full Text Available The aim of this paper is to show the behavior of the working conditions of the rural labor force of Mexico in the context of trade liberalization (1990-2010. Therefore, trends in agricultural and non-agricultural occupations are reviewed; salaried and non-salaried activities; labor income; and the main demographic characteristic of labor as age and schooling. The empirical analysis shows processing micro-data samples from the Census of Population and Housing 1990, 2000 and 2010. Among the major results in low growth of wage employment in rural contexts, both agricultural and non-agricultural activities is found. The female agricultural wage labor grew to early twenty-first century and later had a contraction at the end of the decade two thousand. Males still predominantly in farming, but it has increased its participation in the agricultural wage labor. Non-agricultural occupations increased in rural contexts. However, at the last moment of the study became more precarious, as the increased work on their own, with low levels of remuneration, this situation reflects the limited labor demand of labor. Therefore, in the context of trade liberalization, not salaried occupations increased steadily and continues with low levels of remuneration. The geographic region of residence enabled to distinguish differences in the working conditions of the rural population and occupied in time regional wage gap it is slightly shortened. The Northwest, North region were showing the highest levels of labor remuneration, in contrast, the South and Gulf regions were those that had the lowest wages.

    2018-02-01

    In recent years, various auxetic material structures have been designed and fabricated for diverse applications that utilize normal materials that follow Hooke’s law but still show the properties of negative Poisson’s ratios (NPR). One potential application is body protection pads that are comfortable to wear and effective in protecting body parts by reducing impact force and preventing injuries in high-risk individuals such as elderly people, industrial workers, law enforcement and military personnel, and athletes. This paper reports an integrated theoretical, computational, and experimental investigation conducted for typical auxetic materials that exhibit NPR properties. Parametric 3D CAD models of auxetic structures such as re-entrant hexagonal cells and arrowheads were developed. Then, key structural characteristics of protection pads were evaluated through static analyses of FEA models. Finally, impact analyses were conducted through dynamic simulations of FEA models to validate the results obtained from the static analyses. Efforts were also made to relate the individual and/or combined effect of auxetic structures and materials to the overall stiffness and shock-absorption performance of the protection pads. An advanced additive manufacturing (3D printing) technique was used to build prototypes of the auxetic structures. Three different materials typically used for fused deposition modeling technology, namely polylactic acid (PLA) and thermoplastic polyurethane material (NinjaFlex® and SemiFlex®), were used for different stiffness and shock-absorption properties. The 3D printed prototypes were then tested and the results were compared to the computational predictions. The results showed that the auxetic material could be effective in reducing the shock forces. Each structure and material combination demonstrated unique structural properties such as stiffness, Poisson’s ratio, and efficiency in shock absorption. Auxetic structures showed better shock

    Full Text Available In this paper will be examined some important issues of the labor market policies in Albania. As well, the analysis of labor market institutions such as the Social Insurances or the Syndicates on the efficiency of employing active labor forces. Which are the policies on the protection of the labor forces and the criteria of definition of the minimum salary? Furthermore, it continues with the importance of reforms in the labor market policies, to be examined in the labor market aspect as a production factor and as a regulator of the internal market. Fast globalization is causing continuous risk and movement for the active labor forces. The increase and development of technology puts out of the market many employees, decreasing the number of unqualified employees and increases the demand for the qualified ones. Does the globalization really affect the labor market, efficiency and as a consequence increase production, or the latter are benefits only for the developed economic countries? At the same time, we shall examine the movement of the labor forces from one country to another and the fluctuation of the relevant salaries. In general, the analysis of this paper faces two key issues: the first being raised on discussion of the kinds of programs on the active labor forces, such as programs of direct employment or consideration of employment in public sector, and the second regarding the methodology of evaluating these programs. How effective are them on the domestic market? The paper ends with conclusions and recommendations on the efficiency of policies for the labor market forces.

    Although migrant workers are a vulnerable group in China, they demonstrably contribute to the country's economic growth and prosperity. This study aimed to describe and assess the inequality of migrant worker health in China and its association with socioeconomic determinants. The data utilized in this study were obtained from the 2012 China Labor-force Dynamics Survey conducted in 29 Chinese provinces. This study converted the self-rated health of these migrant workers into a general cardinal ill-health score. Determinants associated with migrant worker health included but were not limited to age, marital status, income, and education, among other factors. Concentration index, concentration curve, and decomposition of the concentration index were employed to measure socioeconomic inequality in migrant workers' health. Prorich inequality was found in the health of migrant workers. The concentration index was -0.0866, as a score indicator of ill health. Decomposition of the concentration index revealed that the factors most contributing to the observed inequality were income, followed by gender, age, marital status, and smoking history. It is generally known that there is an unequal socioeconomic distribution of migrant worker health in China. In order to reduce the health inequality, the government should make a substantial effort to strengthen policy implementation in improving the income distribution for vulnerable groups. After this investigation, it is apparent that the findings we have made warrant further investigation. Copyright © 2016. Published by Elsevier Taiwan LLC.

    Wang, Mei-Ling; Chang, Shu-Chen

    2016-06-01

    Healthcare is a profession that requires a high level of emotional labor (EL). Nurses provide frontline services in hospitals and thus typically experience high levels of EL. The quality of services that nurses provide impacts on how patients evaluate the service quality of hospitals. The aim of this study is to explore the relationships among EL, job involvement (JI), and customer-oriented behavior (COB) in the context of the nursing profession. The participants in this study were nurses at eight hospitals, all located in Taiwan. This study used a self-reporting questionnaire. Research data were gathered at two discrete periods (A and B). Questionnaire A collected data on EL and JI, and Questionnaire B collected data on COB. Five hundred questionnaires were sent out to qualified participants, and 472 valid questionnaires were returned. Hierarchical regression analysis was used to test the hypotheses. The expression of positive emotion (EPE) and the suppression of negative emotion (SNE) were found to positively affect the patient-oriented COB. Furthermore, the EPE was found to positively affect the task-oriented COB. In terms of the moderating effect of JI, JI was found to relate positively to the EPE, patient-oriented COB, and task-oriented COB. In addition, higher values of JI were found to weaken the relationship between the SNE and the task-oriented COB. It has become an increasingly popular practice for hospital organizations to work to promote the COB of their nursing staffs. The results of this study prove empirically that a relationship exists among EL, COB, and JI in nurses. This study contributes to the related literature, enhances the knowledge of hospital and nursing administrators with regard to EL and COB, and offers a reference for hospital managers who are responsible for designing and executing multidisciplinary programs and for managing hospital-based human resources.

    The individual behavior model is a contributory factor to improve the accuracy of agent-based simulation in different scenarios. However, few studies have considered moving threat agents, which often occur in terrorist attacks caused by attackers with close-range weapons (e.g., sword, stick). At the same time, many existing behavior models lack validation from cases or experiments. This paper builds a new individual behavior model based on seven behavioral hypotheses. The driving-forces model is an extension of the classical social force model considering scenarios including moving threat agents. An experiment was conducted to validate the key components of the model. Then the model is compared with an advanced Elliptical Specification II social force model, by calculating the fitting errors between the simulated and experimental trajectories, and being applied to simulate a specific circumstance. Our results show that the driving-forces model reduced the fitting error by an average of 33.9% and the standard deviation by an average of 44.5%, which indicates the accuracy and stability of the model in the studied situation. The new driving-forces model could be used to simulate individual behavior when analyzing the risk of specific scenarios using agent-based simulation methods, such as risk analysis of close-range terrorist attacks in public places.

    Full Text Available The aim of the study is to analyze the extent of the presence of migrants and their behavior in the Russian labor market on the basis of largescale sociological surveys of migrants. This is especially important in the absence of reliable statistics on migrants in the labor market. The main attention is paid to the employment profiles of representatives of various socio-demographic and ethnic groups, illegal and informal employment, the intensity and wages of migrants from countries with a visa-free regime with Russia. Particular attention is paid to labor mobility of migrants. The main empirical basis for analysis was the results of sociological polls conducted by the Center for Ethnopolitical and Regional Studies for the Higher School of Economics in 2011. (8,5 thousand respondents and in 2017 (8,6 thousand migrants in 19 regions of Russia. The study showed that education, qualifications, professional knowledge of migrants are not in demand on the Russian market, the typical path of migrants in the labor market is downward labor mobility – occupying a job that is worse than previously occupied in the homeland. At the same time, migrants are adapted to changes in the labor market, which is largely facilitated by the differentiation of migrant employment and the vertical mobility of some of them. Innovations in Russian legislation which came into force in 2015, as well as the integration process within the framework of the Eurasian Economic Union (EEA, which greatly facilitated access to jobs in Russia for citizens of the countries of the EEA, had a positive impact on the Russian labor market. The share of illegally employed migrants has significantly decreased in comparison with previous years. At the same time, the problem of informal employment of foreign citizens, excessive exploitation of migrant labor remains. The problems of combating forced labor of migrants and ensuring their decent labor come to the fore. Civilized conditions should

    Casino exclusion programs are intended to prevent or limit gambling-related harm. Although previous research showed that self-exclusion is associated with reduced gambling, it remains unknown whether self- and forced excluded subjects show different patterns of gambling behavior and if exclusion from casino gambling affects all gambling activities. The present study retrospectively investigated (1) the role of voluntariness of exclusion for the first time, and (2) general gambling behavior of excluded individuals before and after exclusion. A total of N = 215 casino excluders (self-excluders: n = 187, forced excluders: n = 28) completed an online survey or a face-to-face interview up to 8 years after enrollment. Self- and forced excluders showed similar rates of abstinence (self-excluders: 19.3%, forced excluders: 28.6%) and reduction (self-excluders: 67.4%, forced excluders: 60.7%), even though forced excluders reported a significantly greater initial gambling intensity compared to self-excluders (e.g., pre-exclusion gambling time; self-excluders: 3.2 days/week, forced excluders: 4.3 days/week). Overall, results indicated that 20.5% of excluders stopped all gambling activities and another 66.5% reduced their gambling. Those who continued gambling significantly reduced this behavior in every segment, except for gambling halls. Findings indicate that self- and forced exclusion are associated with similarly reduced gambling behavior, even in non-excluded segments. However, unchanged gambling in gambling halls emphasizes the importance to implement consistent exclusion programs over all gambling segments.

  5. Effect of three-body forces on the phase behavior of charged colloids

    Statistical-thermodynamic theory for predicting the phase behavior of a colloidal solution requires the pair interaction potential between colloidal particles in solution. In practice, it is necessary to assume pairwise additivity for the potential of mean force between colloidal particles, but little is known concerning the validity of this assumption. This paper concerns interaction between small charged colloids, such as surfactant micelles or globular proteins, in electrolyte solutions and the multibody effect on phase behavior. Monte Carlo simulations for isolated colloidal triplets in equilateral configurations show that, while the three-body force is repulsive when the three particles are near contact, it becomes short-ranged attractive at further separations, contrary to a previous study where the triplet force is attractive at all separations. The three-body force arises mainly from hard-sphere collisions between colloids and small ions; it is most significant in solutions of monovalent salt at low concentration where charged colloids experience strong electrostatic interactions. To illustrate the effect of three-body forces on the phase behavior of charged colloids, we calculated the densities of coexisting phases using van der Waals-type theories for colloidal solutions and for crystals. For the conditions investigated in this work, even though the magnitude of the three-body force may be as large as 10% of the total force at small separations, three-body forces do not have a major effect on the densities of binary coexisting phases. However, coexisting densities calculated using Derjaguin-Landau-Verwey-Overbeek theory are much different from those calculated using our simulated potential of mean force.

    Tapping mode atomic force microscopy (AFM) provides phase images in addition to height and amplitude images. Although the behavior of tapping mode AFM has been investigated using mathematical modeling, comprehensive understanding of the behavior of tapping mode AFM still poses a significant challenge to the AFM community, involving issues such as the correct interpretation of the phase images. In this paper, the cantilever's dynamic behavior in tapping mode AFM is studied through a three dimensional finite element method. The cantilever's dynamic displacement responses are firstly obtained via simulation under different tip-sample separations, and for different tip-sample interaction forces, such as elastic force, adhesion force, viscosity force, and the van der Waals force, which correspond to the cantilever's action upon various different representative computer-generated test samples. Simulated results show that the dynamic cantilever displacement response can be divided into three zones: a free vibration zone, a transition zone, and a contact vibration zone. Phase trajectory, phase shift, transition time, pseudo stable amplitude, and frequency changes are then analyzed from the dynamic displacement responses that are obtained. Finally, experiments are carried out on a real AFM system to support the findings of the simulations. © 2015 Wiley Periodicals, Inc.

    To compare the effects of the antidepressant drugs duloxetine and fluoxetine on depressive behaviors in rodents. Eighteen male Wistar rats were given systemic injections of duloxetine, fluoxetine, or saline prior to a Forced Swimming Test (FST). Immobility and number of stops were measured. Rats given injections of fluoxetine displayed significantly less immobility (p = 0.02) and fewer stops than the control group (p = 0.003). Duloxetine significantly reduced the number of stops (p = 0.003), but did not effect immobility (p = 0.48). Duloxetine and fluoxetine reduced depressive behaviors in the Forced FST. However, our findings suggest that fluoxetine is more effective than duloxetine.

    For demographic reasons, the German labor force will decrease dramatically and it will be much older on average. However, labor demand, especially for qualified workers, is expected to remain high. This paper focuses on the possibilities of expanding the labor force by increasing the participation rates of women and older persons. Herein, the change in the labor force is decomposed with respect to population and labor participation and, moreover, the effects of higher participation rates are simulated. The decomposition and simulation scenarios are based on data published by the Institute for Employment Research. The analysis clearly reveals that the effect of a considerably higher labor participation of women and older workers will disappear over time when the working-age population shrinks more and more. In addition, individuals who are currently unemployed or out of the labor force are not skilled enough. Since it seems difficult to get more qualified workers in the short and even in the medium term, improving the conditions for women and older people to take up jobs should be tackled soon. This includes investments in education and health care.

    This study investigated age-related changes in behavioral and neural complexity for a polyrhythmic movement, which appeared to be an exception to the loss of complexity hypothesis. Young (n = 15; age = 24.2 years) and older (15; 68.1 years) adults performed low-level force-tracking with isometric index abduction to couple a compound sinusoidal target. Multi-scale entropy (MSE) of tracking force and inter-spike interval (ISI) of motor unit (MU) in the first dorsal interosseus muscle were assessed. The MSE area of tracking force at shorter time scales of older adults was greater (more complex) than that of young adults, whereas an opposite trend (less complex for the elders) was noted at longer time scales. The MSE area of force fluctuations (the stochastic component of the tracking force) were generally smaller (less complex) for older adults. Along with greater mean and coefficient of ISI, the MSE area of the cumulative discharge rate of elders tended to be lower (less complex) than that of young adults. In conclusion, age-related complexity changes in polyrhythmic force-tracking depended on the time scale. The adaptive behavioral consequences could be multi-factorial origins of the age-related impairment in rate coding, increased discharge noises, and lower discharge complexity of pooled MUs.

  15. The compensatory interaction between motor unit firing behavior and muscle force during fatigue.

    Throughout the literature, different observations of motor unit firing behavior during muscle fatigue have been reported and explained with varieties of conjectures. The disagreement amongst previous studies has resulted, in part, from the limited number of available motor units and from the misleading practice of grouping motor unit data across different subjects, contractions, and force levels. To establish a more clear understanding of motor unit control during fatigue, we investigated the firing behavior of motor units from the vastus lateralis muscle of individual subjects during a fatigue protocol of repeated voluntary constant force isometric contractions. Surface electromyographic decomposition technology provided the firings of 1,890 motor unit firing trains. These data revealed that to sustain the contraction force as the muscle fatigued, the following occurred: 1) motor unit firing rates increased; 2) new motor units were recruited; and 3) motor unit recruitment thresholds decreased. Although the degree of these adaptations was subject specific, the behavior was consistent in all subjects. When we compared our empirical observations with those obtained from simulation, we found that the fatigue-induced changes in motor unit firing behavior can be explained by increasing excitation to the motoneuron pool that compensates for the fatigue-induced decrease in muscle force twitch reported in empirical studies. Yet, the fundamental motor unit control scheme remains invariant throughout the development of fatigue. These findings indicate that the central nervous system regulates motor unit firing behavior by adjusting the operating point of the excitation to the motoneuron pool to sustain the contraction force as the muscle fatigues.

    The behavior of the graphite dust is important to the safety of High Temperature Gas-cooled Reactors. The present study focuses on the forces which make the graphite dust attach or detach from the surface in HTGR. The effect of graphite dust size, the fluid velocity and the surface energy between the particles and the substrate were investigated. The result showed that van der Waals adhesion force is the main factors affecting the dust attach on the surface, the gravity force and the electrostatic force were much smaller than it. For small particles, both the aerodynamic lift and drag are smaller than van der Waals adhesion force. While for the large particles, the coupled effects of aerodynamic lift and drag can make the dust detach from the substrate easier. Both the aerodynamic lift and drag forces will increase quickly as the fluid velocity increases. The surface energy is an important parameter for van der Waals adhesion force, which will decrease as the surface energy decreases. (author)

    We present measurements of the electric potential fluctuations on the surface of highly oriented pyrolytic graphite using electrostatic force and atomic force microscopy. Micrometric domainlike potential distributions are observed even when the sample is grounded. Such potential distributions are unexpected given the good metallic conductivity of graphite because the surface should be an equipotential. Our results indicate the coexistence of regions with "metalliclike" and "insulatinglike" behaviors showing large potential fluctuations of the order of 0.25 V. In lower quality graphite, this effect is not observed. Experiments are performed in Ar and air atmospheres.

    Full Text Available Error amplification (EA feedback is a promising approach to advance visuomotor skill. As error detection and visuomotor processing at short time scales decline with age, this study examined whether older adults could benefit from EA feedback that included higher-frequency information to guide a force-tracking task. Fourteen young and 14 older adults performed low-level static isometric force-tracking with visual guidance of typical visual feedback and EA feedback containing augmented high-frequency errors. Stabilogram diffusion analysis was used to characterize force fluctuation dynamics. Also, the discharge behaviors of motor units and pooled motor unit coherence were assessed following the decomposition of multi-channel surface electromyography (EMG. EA produced different behavioral and neurophysiological impacts on young and older adults. Older adults exhibited inferior task accuracy with EA feedback than with typical visual feedback, but not young adults. Although stabilogram diffusion analysis revealed that EA led to a significant decrease in critical time points for both groups, EA potentiated the critical point of force fluctuations <ΔFc2>, short-term effective diffusion coefficients (Ds, and short-term exponent scaling only for the older adults. Moreover, in older adults, EA added to the size of discharge variability of motor units and discharge regularity of cumulative discharge rate, but suppressed the pooled motor unit coherence in the 13–35 Hz band. Virtual EA alters the strategic balance between open-loop and closed-loop controls for force-tracking. Contrary to expectations, the prevailing use of closed-loop control with EA that contained high-frequency error information enhanced the motor unit discharge variability and undermined the force steadiness in the older group, concerning declines in physiological complexity in the neurobehavioral system and the common drive to the motoneuronal pool against force destabilization.

  1. Compression deformation behaviors of sheet metals at various clearances and side forces

    2015-01-01

    Full Text Available Modeling sheet metal forming operations requires understanding of plastic behaviors of sheet metals along non-proportional strain paths. The plastic behavior under reversed uniaxial loading is of particular interest because of its simplicity of interpretation and its application to material elements drawn over a die radius and underwent repeated bending. However, the attainable strain is limited by failures, such as buckling and in-plane deformation, dependent on clearances and side forces. In this study, a finite element (FE model was established for the compression process of sheet specimens, to probe the deformation behavior. The results show that: With the decrease of the clearance from a very large value to a very small value, four defects modes, including plastic t-buckling, micro-bending, w-buckling, and in-plane compression deformation will occur. With the increase of the side force from a very small value to a very large value, plastic t-buckling, w-buckling, uniform deformation, and in-plane compression will occur. The difference in deformation behaviors under these two parameters indicates that the successful compression process without failures for sheet specimens only can be carried out under a reasonable side force.

    Full Text Available Introduction: Stress is an important factor of depression that causes the changes in various body systems. The forced swim test is a commonly used stressor test where rats are forced to swim in specially constructed tanks for a particular period where there is behavioral activation characterized by vigorous swimming and diving to search for alternate routes of escape. Animal health including human has been shown to be affected by the stressful events of life inducing situation which alters cognition, learning memory and emotional responses, causing mental disorders like depression and anxiety and stress in rats. Methods: The experiment was carried out with 12 healthy albino Wistar female rats weighing about 150-180gms. The animals were randomly divided into two groups of six animals each. Group – I (control, Group – II (Stressed Group. Group –II rats are placed in plastic tanks for 45minutes for15 days. Temperature of water was maintained at 20˚C. During stress phase, the animals will be trained for forced swim test, behavioral changes observed by open field apparatus for emotions, and eight arm maze for memory & leaning, elevated plus maze for anxiety. Results: Forced swim stress causes to a significant change (p<0.05 on cognitive functions: motivation, learning and memory. Forced swim stress is the factor damaging the hippocampus causes repeated immobilization and produce atrophy of dendrites of pyramidal neurons and neuroendocrinological disturbances, controlled by the hypothalamo-pituitary-adrenal axis (HPA. Repeated stress in the form of forced swimming activates the free radical processes leading to an increase in lipid peroxidation in many tissues. Conclusion: This study reveals the effect of repeated forced swim stress causes wide range of adaptive changes in the central nervous system including the elevation of serotonin (5-HT metabolism and an increased susceptibility to affective disorders. The earlier findings have reported

    Exposure to cocaine in early periods of postnatal life has adverse effects on behavior, namely, it induces the display of anxiety and fear-like behaviors that are associated with stress and depression. This study examined the effects of early developmental cocaine exposure in several categories of behavior observed in forced swim test. Male and female Wistar rats were given 15 mg/kg of cocaine hydrochloride/body weight/day, subcutaneously, in two daily doses, from postnatal day (PND) 1 to PND27. Controls were saline injected in the same protocol. In PND26-PND27, rats were placed in a swimming pool during 5 min in two sessions. The categories of behavior studied in this work included horizontal and vertical rotation, vibrissae clean, head clean, fast and slow swim, struggling, floating, sliding, diving, head-diving, and wagging head. Results showed differences in the frequencies of several behavioral categories that allowed the discrimination of the behaviors that may constitute "behavioral despair" indicators, as well as which behaviors are most affected by cocaine exposure. Cocaine groups were less active and more immobile than controls. These results suggest that postnatal exposure to cocaine can produce depression-like effects and affect the ability of these animals to cope with stress situations.

  4. Understanding environment-influenced swarm behavior from a social force perspective

    The relevant research on swarm behavior has focused on the facts that when individuals agree with other members in the system globally consistent behaviors are generated and that individual decisions are completely dominated by other members. In fact, when individuals generate their own behavior strategies, they tend to consider not only the influences of other members but also autonomically consider their current environment. For example, in the social foraging of flocks, the behavior strategy of each individual animal is influenced by the food distribution, and individual movement patterns are characterized by a highly efficient search strategy-Lévy walks. To investigate this, this paper proposes using an environment-driven social force perspective to explore the Lévy walks of individuals in a group in patchy food environments. This model adopts the concept of social force to quantify the social effects and the interactions between individuals and food. The coordination between forces is a key in the formation of individual behavior strategies. Our simulation results show a power-law frequency distribution for agent flight lengths that conforms to Lévy walks and verifies the hypothesis of a relationship between food density and the Lévy index. In our model, the flock still exhibits collective consistency and cohesion and yields a high value for the order parameter and population density when moving between food patches. In addition, our model explains the intraspecific cooperation and competition that occurs during foraging as proposed in related work. The simulation also validates the impact of two inducements for individual behaviors compared with several benchmark models.

    There is no literature mentioning the electromechanical behavior of micro structures driven by traveling electrostatic forces. This article is thus the first to present the dynamics and stabilities of a micro-ring subjected to a traveling electrostatic force. The traveling electrostatic force may be induced by sequentially actuated electrodes which are arranged around the flexible micro-ring. The analysis is based on a linearized distributed model considering the electromechanical coupling effects between electrostatic force and structure. The micro-ring will resonate when the traveling speeds of the electrostatic force approach some critical speeds. The critical speeds are equal to the ratio of the natural frequencies to the wave number of the correlative natural mode of the ring. Apart from resonance, the ring may be unstable at some unstable traveling speeds. The unstable regions appear not only near the critical speeds, but also near some fractions of some critical speeds differences. Furthermore the unstable regions expand with increasing driving voltage. This article may lead to a new research branch on electrostatic-driven micro devices. PMID:22438705

    Piezoelectric tuning fork shear-force structures are widely used as a distance control unit in a scanning near-field optical microscopy. However, the complex dynamic behavior among the micro-tuning forks (TFs), optical fiber probes, and the probe–surface interactions is still a crucial issue to achieve high-resolution imaging or near-field interaction inspections. Based on nonlinear beam tension-bending vibration theory, vibration equations in both longitudinal and lateral directions have been established when the TF structure and the optical fiber are treated as deformable structures. The relationship of the probe–surface interaction induced by Van der Waals force has been analyzed and the corresponding numerical results used to describe the vibrational behavior of the probe approaching the sample surface are obtained. Meanwhile, the viscous resistance of the liquid film on the sample surface has also been investigated using linear beam-bending vibration theory. Experiments testing the interaction between the probe and the water film on a single crystal silicon wafer have been carried out and the viscous resistance of the water film was estimated using the established equations. Finally, to use the TF-probe structure as a force sensor, the relation between the dynamic response of the TF-probe system and an external force on the probe tip was obtained. - Highlights: • Nonlinear vibration equation is established for a deformable tuning fork probe assembly. • Probe–sample interactions induced by Van der Waals force and viscous resistance are investigated. • The viscous resistance between the probe and the water film is estimated using testing results.

    Unlike in most of the world, HIV incidence in the former Soviet Union continues to rise. While international labor migration has been identified as a potentially important contributor to this trend, most attention has been focused on risks of male migrants themselves. This study uses recent household survey data to examine HIV-related perceptions and actions of migrants' left-behind wives in Armenia. Multivariate logistic regression analyses show that migrants' wives are significantly more likely to suspect their husbands of extramarital sex than are non-migrants' wives. The analyses detect greater worries about HIV infection and a higher likelihood of spousal communication on HIV matters among migrants' wives, compared to non-migrants' wives, but these differences are largely explained by the suspicion of husband's extramarital sex. Finally, no difference between the two categories of women in the probability of consistent condom use with husbands is found. These findings are interpreted within the context of patriarchal culture and unequal gender relations in Armenian society as they are further reinforced by male migration. Implications of these findings for policies to increase women's awareness of HIV risks associated with migration and their ability to reduce those risks are discussed.

    This paper examines the association between alcohol consumption and sexual risk behaviors (unprotected sex, multiple sex partners, sex under influence of drugs or alcohol and commercial sex) in a sample of Central Asian migrant and non-migrant laborers in the largest marketplace in Kazakhstan. We used data from The Silk Road Health Project, conducted from 2010 to 2013 with 1342 male migrant and non-migrant market workers. Participants were selected through respondent driven sampling at the Baraholka Market in Almaty, Kazakhstan. We used regression analyses adjusting for potential confounders to examine the relationship between alcohol consumption and sexual risk behavior. We found that hazardous drinking was associated with an increase in the odds of sex under the influence of drugs (aOR = 6.09, 95% CI 3.48, 10.65; p < .001) and purchasing commercial sex (aOR = 2.02, 95% CI 1.02, 4.02; p < .05). We identified potential targets for HIV interventions to reduce sexual risk behaviors among this key population.

    AFM was used to collect the whole force–deformation cell curves. They provide both the elasticity and adhesion behavior of mouse primary cardiac fibroblasts. To confirm the hypothesis that a link exists between the membrane receptors and the cytoskeletal filaments causing therefore changing in both elasticity and adhesion behavior, actin-destabilizing Cytochalsin D was administrated to the fibroblasts. From immunofluorescence observation and AFM loading/unloading curves, cytoskeletal reorganization as well as a change in the elasticity and adhesion was indeed observed. Elasticity of control fibroblasts is three times higher than that for fibroblasts treated with 0.5 μM Cytochalasin. Moreover, AFM loading–unloading curves clearly show the different mechanical behavior of the two different cells analyzed: (i) for control cells the AFM cantilever rises during the dwell time while cells with Cytochalasin fail to show such an active resistance; (ii) the maximum force to deform control cells is quite higher and as far as adhesion is concern (iii) the maximum separation force, detachment area and the detachment process time are much larger for control compared to the Cytochalasin treated cells. Therefore, alterations in the cytoskeleton suggest that a link must exist between the membrane receptors and the cytoskeletal filaments beneath the cellular surface and inhibition of actin polymerization has effects on the whole cell mechanical behavior as well as adhesion. - Highlights: • The whole AFM force–deformation cell curves were analyzed. • They provide information on both the elasticity and adhesion behavior. • Actin-destabilizing Cytochalasin D was administrated to the fibroblasts. • Change in elasticity and adhesion was ascribed to cytoskeletal reorganization. • A link exists between the membrane receptors and the cytoskeletal filaments.

    The controlled and directed focusing of particles within flowing fluids is a problem of fundamental and technological significance. Microfluidic inertial focusing provides passive and precise lateral and longitudinal alignment of small particles without the need for external actuation or sheath fluid. The benefits of inertial focusing have quickly enabled the development of miniaturized flow cytometers, size-selective sorting devices, and other high-throughput particle screening tools. Straight channel inertial focusing device design requires knowledge of fluid properties and particle-channel size ratio. Equilibrium behavior of inertially focused particles has been extensively characterized and the constitutive phenomena described by scaling relationships for straight channels of square and rectangular cross section. In concentrated particle suspensions, however, long-range hydrodynamic repulsions give rise to complex particle ordering that, while interesting and potentially useful, can also dramatically diminish the technique’s effectiveness for high-throughput particle handling applications. We have empirically investigated particle focusing behavior within channels of increasing aspect ratio and have identified three scaling regimes that produce varying degrees of geometrical ordering between focused particles. To explore the limits of inertial particle focusing and identify the origins of these long-range interparticle forces, we have explored equilibrium focusing behavior as a function of channel geometry and particle concentration. Experimental results for highly concentrated particle solutions identify equilibrium thresholds for focusing that scale weakly with concentration and strongly with channel geometry. Balancing geometry mediated inertial forces with estimates for interparticle repulsive forces now provide a complete picture of pattern formation among concentrated inertially focused particles and enhance our understanding of the fundamental limits

    This study aimed to observe the multicellular spinning behavior of Proteus mirabilis by atomic force microscopy (AFM) and multifunctional microscopy in order to understand the mechanism underlying this spinning movement and its biological significance. Multifunctional microscopy with charge-coupled device (CCD) and real-time AFM showed changes in cell structure and shape of P. mirabilis during multicellular spinning movement. Specifically, the morphological characteristics of P. mirabilis, multicellular spinning dynamics, and unique movement were observed. Our findings indicate that the multicellular spinning behavior of P. mirabilis may be used to collect nutrients, perform colonization, and squeeze out competitors. The movement characteristics of P. mirabilis are vital to the organism's biological adaptability to the surrounding environment. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Highlights: ► Experimental results on hysteretic behavior of the levitaion force are presented. ► Hysteresis loop for the first descent/ascent cycle of magnet is largest. ► Hysteresis loop for the second and subsequent cycles almost overlap each other. ► Yang’s frozen-image model cannot describe this characteristic of levitation force. ► An updated frozen-image model is developed to describe these experimental results. -- Abstract: The hysteretic behavior of the levitation force between a permanent magnet and a melt-textured-growth YBCO bulk has been investigated under both zero-field cooling (ZFC) and field cooling (FC) processes. It is found that both in ZFC and FC measurements, the hysteresis loop for the first descent/ascent cycle of magnet is relatively larger than that for the second or third cycle, and the hysteresis loops for Cycle 2–4 have the same area. These results can be qualitatively understood in terms of the critical state model. To describe these experimental results, we develop an updated frozen-image model, which is obtained by modifying the change rules of the vertical movement image in the advanced frozen-image model proposed by Yang et al. Comparing with the advanced frozen-image model proposed by Yang et al., our model cannot only give the hysteretic characteristic in the first descent–ascent cycle of magnet, but also show the hysteresis loops with the same area for the second and subsequent cycles.

    A large number of Mexican migrants are deported to Mexico and released in the North Mexican border region every year. Despite their volume and high vulnerability, little is known about the level of HIV infection and related risk behaviors among this hard-to-reach population. We conducted a cross-sectional, probability survey with deported Mexican migrants in Tijuana, Mexico (N=693) and estimated levels of HIV infection and behavioral risk factors among this migrant flow. The sample and population estimated rates of HIV for deported males were 1.23% and 0.80%, respectively. No positive cases were found among the female sample. We found high lifetime rates of reported sexually transmitted infections (22.3%) and last 12-months rates of unprotected sex (63.0%), sex with multiple sexual partners (18.1%), casual partners (25.7%), and sex workers (8.6%), compared to U.S. and Mexico adults. HIV prevention, testing, and treatment programs for this large, vulnerable, and transnational population need to be implemented in both the U.S. and Mexico. PMID:22562390

    This paper is one of only a few studies to examine potential labor market consequences of heavy or abusive drinking in Latin America and the first to focus on Uruguay. We analyzed data from a Uruguayan household survey conducted in 2006 using propensity score matching methods and controlling for a number of socio-demographic, family, regional, behavioral health, and labor market characteristics. As expected, we found a positive association between heavy drinking and absenteeism, particularly for female employees. Counter to the findings for developed countries, our results revealed a positive relationship between heavy drinking and labor force participation or employment. This result was mostly driven by men and weakened when considering more severe measures of abusive drinking. Possible explanations for these findings are that employment leads to greater alcohol use through an income effect, that the Uruguayan labor market rewards heavy drinking, or that labor market characteristics typical of less developed countries, such as elevated safety risks or job instability, lead to problem drinking. Future research with panel data should explore these possible mechanisms. Copyright (c) 2009 John Wiley & Sons, Ltd.

    Forced limb-use can enhance neurogenesis and behavioral recovery as well as increasing the level of stromal cell-derived factor-1 (SDF-1) in stroke rats. We examined whether the SDF-1/CXCR4 pathway is involved in the enhanced neurogenesis and promoted behavioral recovery induced by forced limb-use in the chronic phase of stroke. The CXCR4 antagonist, AMD3100, was used to block the SDF-1/CXCR4 pathway in the ischemic rats. Brain ischemia was induced by endothelin-1. One week after ischemia, the unimpaired forelimb of rats was immobilized for 3 weeks. The proliferation, migration, and survival of DCX-positive cells in the subventricular zone (SVZ), and the dendritic complexity of DCX-positive cells in the dentate gyrus (DG), as well as the inflammatory response in the infarcted striatum were analyzed by immunohistochemistry. Functional recovery was assessed in beam-walking and water maze tests. Forced limb-use enhanced the proliferation, migration, dendritic complexity and the survival of newborn neurons. Furthermore, forced limb-use suppressed the inflammatory response and improved both motor and cognitive functions after stroke. AMD3100 significantly abrogated the enhanced neurogenesis and behavioral recovery induced by forced limb-use without influencing the inflammatory response. SDF-1/CXCR4 pathway seems to be involved in the enhancement of neurogenesis and behavioral recovery induced by post-stroke forced limb-use.

    Secondhand smoke (SHS) is a major risk factor for poor health outcomes among women in China, where proportionately few women smoke. This is especially the case as it pertains to women's reproductive health, specifically migrant women who are exposed to SHS more than the population at large. There are several factors which may increase migrant women's risk of SHS exposure. This paper aims to investigate the prevalence and associated factors of SHS exposure among internal Chinese migrant women of reproductive age. The data used were derived from the 2014 Chinese Labor Dynamic Survey, a national representative panel survey. The age-adjusted rate of SHS exposure of women of reproductive age with migration experience was of 43.46% (95% CI: 40.73%-46.40%), higher than those without migration experience (35.28% (95% CI: 33.66%-36.97%)). Multivariate analysis showed that participants with a marital status of "Widowed" had statistically lower exposure rates, while those with a status of "Cohabitation" had statistically higher exposure. Those with an undergraduate degree or above had statistically lower SHS exposure. Those with increasing levels of social support, and those who currently smoke or drink alcohol, had statistically higher SHS exposure. Participants' different work-places had an effect on their SHS exposure, with outdoor workers statistically more exposed. Our findings suggest that urgent tobacco control measures should be taken to reduce smoking prevalence and SHS exposure. Specific attention should be paid to protecting migrant women of reproductive age from SHS.

  13. Effects of task and age on the magnitude and structure of force fluctuations: insights into underlying neuro-behavioral processes.

    The present study aimed at characterizing the effects of increasing (relative) force level and aging on isometric force control. To achieve this objective and to infer changes in the underlying control mechanisms, measures of information transmission, as well as magnitude and time-frequency structure of behavioral variability were applied to force-time-series. Older adults were found to be weaker, more variable, and less efficient than young participants. As a function of force level, efficiency followed an inverted-U shape in both groups, suggesting a similar organization of the force control system. The time-frequency structure of force output fluctuations was only significantly affected by task conditions. Specifically, a narrower spectral distribution with more long-range correlations and an inverted-U pattern of complexity changes were observed with increasing force level. Although not significant older participants displayed on average a less complex behavior for low and intermediate force levels. The changes in force signal's regularity presented a strong dependence on time-scales, which significantly interacted with age and condition. An inverted-U profile was only observed for the time-scale relevant to the sensorimotor control process. However, in both groups the peak was not aligned with the optimum of efficiency. Our results support the view that behavioral variability, in terms of magnitude and structure, has a functional meaning and affords non-invasive markers of the adaptations of the sensorimotor control system to various constraints. The measures of efficiency and variability ought to be considered as complementary since they convey specific information on the organization of control processes. The reported weak age effect on variability and complexity measures suggests that the behavioral expression of the loss of complexity hypothesis is not as straightforward as conventionally admitted. However, group differences did not completely vanish

    In this study, we show that an adaptation of the spinning test can be used as a model to study the exercise-exhaustion-recovery paradigm in fish. This forced swimming test promotes a wide range of changes in the hypothalamus-pituitary-interrenal axis functioning, intermediary metabolism, as well in fish behavior at both exercise and recovery periods. Our results pointed that this adapted spinning test can be considered a valuable tool for evaluating drugs and contaminant effects on exercised fish. This can be a suitable protocol both to environmental-to evaluate contaminants that act in fish energy mobilization and recovery after stressors-and translational perspectives-effects of drugs on exercised or stressed humans.

  16. SPH for impact force and ricochet behavior of water-entry bodies

    Omidvar, Pourya; Farghadani, Omid; Nikeghbali, Pooyan

    The numerical modeling of fluid interaction with a bouncing body has many applications in scientific and engineering application. In this paper, the problem of water impact of a body on free-surface is investigated, where the fixed ghost boundary condition is added to the open source code SPHysics2D1 to rectify the oscillations in pressure distributions with the repulsive boundary condition. First, after introducing the methodology of SPH and the option of boundary conditions, the still water problem is simulated using two types of boundary conditions. It is shown that the fixed ghost boundary condition gives a better result for a hydrostatics pressure. Then, the dam-break problem, which is a bench mark test case in SPH, is simulated and compared with available data. In order to show the behavior of the hydrostatics forces on bodies, a fix/floating cylinder is placed on free surface looking carefully at the force and heaving profile. Finally, the impact of a body on free-surface is successfully simulated for different impact angles and velocities.

    In this study, the contactless grasp of a magnetic particle suspended in a fluid at rest or in motion by coil current control, and a method for estimating these forces quantitatively were developed. Four electromagnets were used to apply magnetic fields to magnetic ferrite particles (diameter, 300 nm–300 µm) in a fluid in a vessel. Particle-tracking velocimetry with high-speed image processing was used to visualize the behavior of the magnetic particles in the fluid. In addition, contactless grasp of a magnetic particle using the feedback control was accomplished. Furthermore, by making the magnetic force and the resultant force of the other forces affecting a magnetic particle be in balance, the vertical and horizontal forces affecting the minute magnetic particle, such as the viscous force or the magnetic force between magnetized particles, could be estimated quantitatively from the current in the coil of each electromagnet, without any physical contact with the particle itself. These results constitute useful information for studies on the issues in the handling of micro- or nano-particles. - Highlights: • Four electromagnets are used to apply magnetic field to magnetic ferrite particles. • Motion of magnetic particles suspended in a resting or flowing fluid is visualized. • Contactless grasp of a magnetic particle using feedback control was accomplished. • Vertical and horizontal forces affecting a particle can be estimated quantitatively. • Force between magnetized particles which approach to each other was measured

    2016-01-01

    Macromolecules with ionizable groups are ubiquitous in biological and synthetic systems. Due to the complex interaction between chain and electrostatic decorrelation lengths, both equilibrium properties and micro-mechanical response of dilute solutions of polyelectrolytes (PEs) are more complex than their neutral counterparts. In this work, the bead-rod micromechanical description of a chain is used to perform hi-fidelity Brownian dynamics simulation of dilute PE solutions to ascertain the self-similar equilibrium behavior of PE chains with various linear charge densities, scaling of the Kuhn step length (lE) with salt concentration cs and the force-extension behavior of the PE chain. In accord with earlier theoretical predictions, our results indicate that for a chain with n Kuhn segments, lE ˜ cs-0.5 as linear charge density approaches 1/n. Moreover, the constant force ensemble simulation results accurately predict the initial non-linear force-extension region of PE chain recently measured via single chain experiments. Finally, inspired by Cohen's extraction of Warner's force law from the inverse Langevin force law, a novel numerical scheme is developed to extract a new elastic force law for real chains from our discrete set of force-extension data similar to Padè expansion, which accurately depicts the initial non-linear region where the total Kuhn length is less than the thermal screening length.

    Preventing HIV infection is a priority for militaries. HIV prevention research is needed to monitor existing programs, identify areas for modification, and develop new interventions. Correct and consistent condom use is highly effective against HIV. However, use among soldiers is lower than ideal. This study describes condom use behaviors and examines correlates of use in the Botswana Defence Force (BDF). Analyses were based on 211 male personnel, aged 18–30, who completed a cross-sectional survey that collected baseline data for an intervention study. Results showed that 51% of participants reported always using condoms, 35% used condoms most times, and 14% used condoms occasionally/never. Condom use varied by partner type and was typically higher with casual partners in comparison to regular partners. After adjustment for age and marital status, factors associated with lower condom use included excessive alcohol use, perception that using condoms reduce sexual pleasure, and having a trusted partner. However, higher levels of HIV knowledge and reports of being circumcised were protective against lower condom use. HIV interventions aimed at increasing condom use in the BDF should address condom perceptions, alcohol abuse, and issues of trust. Innovative ways to increase condom use in this population should also be explored. PMID:23970609

  5. Mode-locking behavior of Izhikevich neurons under periodic external forcing

    Farokhniaee, AmirAli; Large, Edward W.

    2017-06-01

    Many neurons in the auditory system of the brain must encode periodic signals. These neurons under periodic stimulation display rich dynamical states including mode locking and chaotic responses. Periodic stimuli such as sinusoidal waves and amplitude modulated sounds can lead to various forms of n :m mode-locked states, in which a neuron fires n action potentials per m cycles of the stimulus. Here, we study mode-locking in the Izhikevich neurons, a reduced model of the Hodgkin-Huxley neurons. The Izhikevich model is much simpler in terms of the dimension of the coupled nonlinear differential equations compared with other existing models, but excellent for generating the complex spiking patterns observed in real neurons. We obtained the regions of existence of the various mode-locked states on the frequency-amplitude plane, called Arnold tongues, for the Izhikevich neurons. Arnold tongue analysis provides useful insight into the organization of mode-locking behavior of neurons under periodic forcing. We find these tongues for both class-1 and class-2 excitable neurons in both deterministic and noisy regimes.

  6. A novel approach to forced vibration behavior of thick-walled cylinders

    2016-01-01

    This study is to investigate the effect of anisotropy on the forced vibration behavior of hollow cylinders under dynamic internal pressure. The problems are solved analytically in the Laplace domain, and the results obtained are transformed to the real-time space using the modified Durbin's numerical inversion method. Durbin's numerical inverse method into the analysis of transient thermal stresses in annular fins is a novel approach. Durbin's numerical inverse method successfully implements the boundary value problem which can be solved in Laplace space. Various material models from the literature are used and corresponding radial displacement distributions and stress distributions are computed. Verification of the proposed method is done using benchmark solutions available in the literature for some special cases and virtually exact results are obtained. The anisotropy constant is a useful parameter from a design point of view in that it can be tailored for specific applications to control the stress distribution. - Highlights: • Dynamic analysis of pressure vessel structures is performed. • A novel unified approach; Laplace transforms and Durbin's numerical inversion method is implemented. • The method used allows the presence of continuous as well as discrete functions. • The unified method used is accurate and more efficient than the conventional methods.

    When massless excitations are limited or modified by the presence of material bodies one observes a force acting between them generally called Casimir force. Such excitations are present in any fluid system close to its true bulk critical point. We derive exact analytical results for both the temperature and external ordering field behavior of the thermodynamic Casimir force within the mean-field Ginzburg-Landau Ising type model of a simple fluid or binary liquid mixture. We investigate the case when under a film geometry the boundaries of the system exhibit strong adsorption onto one of the phases (components) of the system. We present analytical and numerical results for the (temperature-field) relief map of the force in both the critical region of the film close to its finite-size or bulk critical points as well as in the capillary condensation regime below but close to the finite-size critical point.

  13. Effect of transient wave forcing on the behavior of arsenic in a sandy nearshore aquifer

    Waves cause large quantities of coastal water to recirculate across the groundwater-coastal water interface in addition to inducing complex groundwater flows in the nearshore aquifer. Due to the distinct chemical composition of recirculating coastal water compared with discharging terrestrial groundwater, wave-induced recirculations and flows can alter geochemical gradients in the nearshore aquifer which may subsequently affect the mobilization and transport of reactive pollutants (e.g., arsenic). The impact of seasonal geochemical and hydrological variability on the occurrence and mobility of arsenic near the groundwater-surface water interface has been shown previously in riverine settings, however, the impact of high frequency geochemical variations (e.g., varying wave conditions) on arsenic mobility in groundwater-surface water environments is unclear. The objective of the study was to assess the impact of intensified wave conditions on the behavior of arsenic in a nearshore aquifer to determine the factors regulating its mobility and transport to receiving coastal waters. Field investigations were conducted at a permeable beach on the Great Lakes during a period of intensified wave conditions (wave event). High spatial resolution pore water sampling captured the geochemical conditions in the nearshore aquifer prior to the wave event, immediately after the wave event and over a recovery period of 3 weeks following the wave event. Shifts in pH and redox potential (ORP) gradients in response to varying wave conditions caused shifts in the iron and arsenic distributions in the aquifer. Sediment analysis was combined with the pore water distributions to assess the release of sediment-bound arsenic in response to the varying wave conditions. Insight into the effect of transient forcing on arsenic mobility and transport in groundwater-surface water environments is important for evaluating the potential risks associated with this toxic metalloid. The findings of this

  14. The nature and extent of police use of force in encounters with people with behavioral health disorders.

    Science.gov (United States)

    Morabito, Melissa S; Socia, Kelly; Wik, Amanda; Fisher, William H

    Previous research studies have examined the treatment of people with mental illnesses by the police. Much available data support the adoption of the Crisis Intervention Team (CIT) model. A key issue in CIT development has been reduction in the use of force by CIT officers, and it is suggested that such adoption does accomplish such reduction. However, to date, scant research compares variation in police use of force by CIT officers across populations with mental illnesses, co-occurring disorders, and substance abuse disorders, as compared to their non-disordered peers. Using data from the Portland Police Bureau, a police agency in which all patrol officers have been trained in the CIT model, we analyze whether police use-of-force differs across these groups. Police use-of-force data were collected for 4211 incidents from the Portland Police Bureau from 2008 to 2011. Results indicate that people perceived as having comorbid behavioral health disorders were generally more likely to have force used against them, and more likely to be perceived as resistant, than people that were perceived as having only substance use disorder, only mental health disorders, or no apparent behavioral health disorders. People with co-occurring disorders are more likely to be perceived as violently resisting police officers and have force used against them. Further, people with no perceived disorders are more likely to have a firearm pointed at them in use-of-force encounters, but also the least likely to be perceived as resisting.

    2011-01-01

    A single exposure of rats to the forced-swimming stress decreased BDNF mRNA levels in the cortex and increased Bcl-xl gene expression in the hippocampus and amygdala 24 h after the stress. The animals demonstrated a depressive-like behavior and elevated blood corticosterone level. There was a significant negative correlation between BDNF mRNA level in the cortex and immobility time during swimming. Repeated exposure to swimming stress caused the elevation of the hippocampal BDNF mRNA level assessed 24 h after the second swimming session. The data suggest that stress-induced down-regulation of cortical BDNF gene expression and behavioral despair in the forced-swimming test may be interrelated. The increase in the BDNF and Bcl-xl mRNA levels may contribute to the mechanisms protecting the brain against negative effects of stress.

    Interest in the use of rubber flooring in freestall barns has increased, but little is known about which design features of these surfaces are important for cattle. In 2 experiments, we evaluated how the type and compressibility of the flooring surface in front of the feed bunk influenced the behavioral response to 4 h of forced standing after morning milking. Two flooring types were compared: rubber and concrete. Rubber was tested at 3 levels of compressibility: 2, 4, and 35 times as compressible as concrete. Four hours of forced standing was evaluated because it mimicked conditions that can occur on dairies, particularly when waiting for artificial insemination or veterinary treatment. The effects of cow weight and hoof surface area, gait score, and hoof health on the response to treatment were evaluated. Restless behavior, as measured by number of steps, almost doubled over the 4h of forced standing, regardless of flooring material. Cows lay down, on average, within 5 min after access to the lying area was provided. These results indicate that the 4 h of forced standing was uncomfortable. No differences in restless behavior were observed in association with the type or compressibility of the flooring surface in front of the feed bunk. Cow size, hoof health, or gait score did not consistently explain the response to the flooring treatments or stepping rate, although these populations of animals were generally healthy. It is unclear if comfort did not differ between the flooring options tested during 4 h of forced standing or if alterative methodology, such as measuring more subtle shifts in weight, is required to assess design features of rubber flooring.

  7. Acute behavioral symptomatology at disappearance of epileptiform EEG abnormality. Paradoxical or "forced" normalization.

    Science.gov (United States)

    Wolf, P

    1991-01-01

    Paradoxical or "forced" normalization of the EEG of patients with epilepsy was first described by Landolt in 1953. It refers to conditions where disappearance of epileptiform discharge from the routine scalp EEG is accompanied by some kind of behavioral disorder. The best known of these is a paranoid psychotic state in clear consciousness, which is also known as "alternative" psychosis. Thus, the issue is related to much older observations which indicated a "biological antagonism" between productive psychotic symptomatology and epileptic seizures, which led to the therapy of psychoses with artificially induced convulsions. Apart from psychotic episodes, the clinical manifestations of PN comprise dysphoric states, hysterical and hypochondriacal syndromes, affective disorders, and miscellanea. PN can be observed in both generalized and localization-related epilepsies as a rare complication. A subset where it is more frequently seen are in adults with persistent absence seizures when the latter become finally controlled by succinimide therapy. These seem to be the drugs with the highest hazard of precipitation of PN, but all other AEDs have also been suspected. Sleep disturbance by succinimide treatment may play a crucial role, but a variety of other factors are also involved, including psychosocial factors. The pathogenesis of this condition has given rise to some debate but remains still unresolved. Eleven of the most important hypotheses have been discussed and seem to converge into a more comprehensive hypothesis which basically assumes that, during PN, the epilepsy is still active subcortically, perhaps with spread of discharge along unusual pathways. This activity is supposed to provide energy and, possibly, some of the symptoms included in the psychotic syndrome. A critical clinical condition results, usually with a dysphoric symptomatology, where a development towards psychosis is impending but still depends on the presence or absence of a variety of risk

  8. Toxic cocaine- and convulsant-induced modification of forced swimming behaviors and their interaction with ethanol: comparison with immobilization stress

    Science.gov (United States)

    Hayase, Tamaki; Yamamoto, Yoshiko; Yamamoto, Keiichi

    2002-01-01

    Background Swimming behaviors in the forced swimming test have been reported to be depressed by stressors. Since toxic convulsion-inducing drugs related to dopamine [cocaine (COC)], benzodiazepine [methyl 6,7-dimethoxy-4-ethyl-β-carboline-carboxylate (DMCM)], γ-aminobutyric acid (GABA) [bicuculline (BIC)], and glutamate [N-methyl-D-aspartate (NMDA)] receptors can function as stressors, the present study compared their effects on the forced swimming behaviors with the effects of immobilization stress (IM) in rats. Their interactions with ethanol (EtOH), the most frequently coabused drug with COC which also induces convulsions as withdrawal symptoms but interferes with the convulsions caused by other drugs, were also investigated. Results Similar to the IM (10 min) group, depressed swimming behaviors (attenuated time until immobility and activity counts) were observed in the BIC (5 mg/kg IP) and DMCM (10 mg/kg IP) groups at the 5 h time point, after which no toxic behavioral symptoms were observed. However, they were normalized to the control levels at the 12 h point, with or without EtOH (1.5 g/kg IP). In the COC (60 mg/kg IP) and NMDA (200 mg/kg IP) groups, the depression occurred late (12 h point), and was normalized by the EtOH cotreatment. At the 5 h point, the COC treatment enhanced the swimming behaviors above the control level. Conclusions Although the physiological stress (IM), BIC, and DMCM also depressed the swimming behaviors, a delayed occurrence and EtOH-induced recovery of depressed swimming were observed only in the COC and NMDA groups. This might be correlated with the previously-reported delayed responses of DA and NMDA neurons rather than direct effects of the drugs, which could be suppressed by EtOH. Furthermore, the characteristic psychostimulant effects of COC seemed to be correlated with an early enhancement of swimming behaviors. PMID:12425723

    To compare the behaviors of rats with depressions induced by chronic forced swimming stress under two different conditions. Eighteen male rats were randomly divided into 3 groups, with 6 rats in each group. The rats in the control group (C group) were not forced into swimming, while the rats in the stress groups (S1 and S2) were forced to swim for 14 consecutive days. The rats in S1 group and S2 group swam for five minutes every morning, in water with (23 +/- 1) degree C, and (10 +/- 0.5) degree C in temperature, respectively. The weight gain, food intake, open-field test and saccharin solution test were observed on the seventh day and fourteenth day. On the seventh day following chronic swim stress, the rats in the S2 group had significant lower ratio in weight gain and food intake than the controls (P forced swimming. On the fourteenth day, the rats in the S1 group still had lower ratio in weight gain, but had higher ratio in food intake and preference for saccharin solution, and greater number of crossing than the controls. Chronic forced swimming at a lower temperature could induce depression better than at a higher temperature.

    The influence of hydrodynamic interactions, such as Stokes and Basset forces, on the dynamics of a harmonically trapped Brownian tracer is considered. A generalized Langevin equation is used to describe the tracer’s response to an external periodic force and to dichotomous fluctuations of the stiffness of the trapping potential. Relying on the Shapiro-Loginov formula, exact expressions for the complex susceptibility and for the response function are presented. On the basis of these exact formulas, it is demonstrated that interplay of a multiplicative colored noise and the Basset force induced memory effects can generate a variety of cooperation effects, such as multiresonance versus the driving frequency, as well as stochastic resonance versus noise parameters. In particular, in certain parameter regions the response function exhibits a resonance-like enhancement at intermediate values of the intensity of the Basset force. Conditions for the appearance of these effects are also discussed.

    Melatonin is an essential hormone, which regulates circadian rhythms and has antioxidative and anticarcinogenic effects. As melatonin secretion is suppressed by light, this effect was examined on the offspring of the Wistar rat females exposed to continuous light (500 lux) during the second half of the pregnancy (day 12 to 21). Control rats were kept under a 12:12 light-dark cycle. The resulted male offspring have been behaviorally assessed for depression after postnatal day 60 by using Forced Swim Test (FST) and Tail Suspension Test (TST). Animals resulted from the melatonin deprived pregnancies have developed an abnormal response in the TST, but a normal FST behavior. Also, TST active movement was different in the melatonin suppression group compared to the control group. These findings suggest that intrauterine melatonin deprivation might be linked to the depressive like behavior in adult male offspring.

  14. Division of labor associated with brood rearing in the honey bee: how does it translate to colony fitness?

    Directory of Open Access Journals (Sweden)

    Ramesh R Sagili

    2011-02-01

    Full Text Available Division of labor is a striking feature observed in honey bees and many other social insects. Division of labor has been claimed to benefit fitness. In honey bees, the adult work force may be viewed as divided between non-foraging hive bees that rear brood and maintain the nest, and foragers that collect food outside the nest. Honey bee brood pheromone is a larval pheromone that serves as an excellent empirical tool to manipulate foraging behaviors and thus division of labor in the honey bee. Here we use two different doses of brood pheromone to alter the foraging stimulus environment, thus changing demographics of colony division of labor, to demonstrate how division of labor associated with brood rearing affects colony growth rate. We examine the effects of these different doses of brood pheromone on individual foraging ontogeny and specialization, colony level foraging behavior, and individual glandular protein synthesis. Low brood pheromone treatment colonies exhibited significantly higher foraging population, decreased age of first foraging and greater foraging effort, resulting in greater colony growth compared to other treatments. This study demonstrates how division of labor associated with brood rearing affects honey bee colony growth rate, a token of fitness.

    Of the world's largest child labor force in India, Bombay has over 30,000 working children, most of them migrants. In a prospective study of 73 working children from a part of Dharavi, the biggest slum in Asia, 68% were working as hotel boys; 22% had started working before their 10th birthday, a large number doing so to increase the family income, but earning less than Rs. 100 ($11) per month. Forty percent worked more than 12 hours a day and only 16% continued schooling. Two-thirds depended entirely on their employers for food which was adequate and no child in the study was malnourished. Overall incidence of anemia and vitamin deficiency was 10% each. Only 7% had ailments related to their occupation. Because this was a cross-sectional study no conclusions can be drawn regarding long term and residual effects. Preventing children from working is likely to make worse their own as well as their families' problems unless substitute sources of income or welfare are available. Legal protection and other services near their working places are essential for those who have to work.

Possibly, if they provide firms with a commitment device to not punish short-run failures and thereby incentivize the pursuit of value-maximizing innovative activities. In this paper, we provide empirical evidence that strong labor laws indeed appear to have an ex ante positive incentive effect by encouraging the innovative pursuits of firms and their employees. Using patents and citations as proxies for innovation and a time-varying index of labor laws,...

    A modified energy-balance equation accounting for P-delta effects and hysteretic behavior of reinforced concrete members is derived. Reduced hysteretic properties of structural components due to combined stiffness and strength degradation and pinching effects, and hysteretic damping are taken into account in a simple manner by utilizing plastic energy and seismic input energy modification factors. Having a pre-selected yield mechanism, energy balance of structure in inelastic range is considered. P-delta effects are included in derived equation by adding the external work of gravity loads to the work of equivalent inertia forces and equating the total external work to the modified plastic energy. Earthquake energy input to multi degree of freedom (MDOF) system is approximated by using the modal energy-decomposition. Energy-based base shear coefficients are verified by means of both pushover analysis and nonlinear time history (NLTH) analysis of several RC frames having different number of stories. NLTH analyses of frames are performed by using the time histories of ten scaled ground motions compatible with elastic design acceleration spectrum and fulfilling duration/amplitude related requirements of Turkish Seismic Design Code. The observed correlation between energy-based base shear force coefficients and the average base shear force coefficients of NLTH analyses provides a reasonable confidence in estimation of nonlinear base shear force capacity of frames by using the derived equation.

    The paper studies the issue of stability of solutions to the forced Navier-Stokes and damped Euler systems in periodic boxes. It is shown that for large, but fixed, Grashoff (Reynolds) number the turbulent behavior of all Leray-Hopf weak solutions of the three-dimensional Navier-Stokes equations, in periodic box, is suppressed, when viewed in the right frame of reference, by large enough average flow of the initial data; a phenomenon that is similar in spirit to the Landau damping. Specifically, we consider an initial data which have large enough spatial average, then by means of the Galilean transformation, and thanks to the periodic boundary conditions, the large time independent forcing term changes into a highly oscillatory force; which then allows us to employ some averaging principles to establish our result. Moreover, we also show that under the action of fast oscillatory-in-time external forces all two-dimensional regular solutions of the Navier-Stokes and the damped Euler equations converge to a unique time-periodic solution.

    The healthcare sector was one of the few sectors of the US economy that created new positions in spite of the recent economic downturn. Economic contractions are associated with worsening morbidity and mortality, declining private health insurance coverage, and budgetary pressure on public health programs. This study examines the causes of healthcare employment growth and workforce composition in the US and evaluates the labor market's impact on healthcare spending and health outcomes. Data are collected for 50 states and the District of Columbia from 1999-2009. Labor market and healthcare workforce data are obtained from the Bureau of Labor Statistics. Mortality and health status data are collected from the Centers for Disease Control and Prevention's Vital Statistics program and Behavioral Risk Factor Surveillance System. Healthcare spending data are derived from the Centers for Medicare and Medicaid Services. Dynamic panel data regression models, with instrumental variables, are used to examine the effect of the labor market on healthcare spending, morbidity, and mortality. Regression analysis is also performed to model the effects of healthcare spending on the healthcare workforce composition. All statistical tests are based on a two-sided [Formula: see text] significance of [Formula: see text] .05. Analyses are performed with STATA and SAS. The labor force participation rate shows a more robust effect on healthcare spending, morbidity, and mortality than the unemployment rate. Study results also show that declining labor force participation negatively impacts overall health status ([Formula: see text] .01), and mortality for males ([Formula: see text] .05) and females ([Formula: see text] .001), aged 16-64. Further, the Medicaid and Medicare spending share increases as labor force participation declines ([Formula: see text] .001); whereas, the private healthcare spending share decreases ([Formula: see text] .001).

    Full Text Available In the past decades, the European and Romanian economies have been strongly affected by major changes which have influenced also the labor market: the alert pace of the international economic integration, the creation of work division in order to protect some economic sectors, the accelerated development and implementation of new technologies, the increase of the demographic aging trends. In the context of the amplified labor force crisis, the present paper will analyze some dysfunctions which have affected especially the regional labor market: the chronic unemployment, the mismatch between the demand and the offer of jobs and the localized consequences of the labor migration. The approach on these aspects was done in a vaster context intended to analyze the regional labor market of Galati and Braila, starting from the existent imbalances on these markets. The present paper starts from the premise that the proposal of some measurements which should lead to a balancing of the regional working market, must take into account the way in which the direct actors involved are defining these obstacles and opportunities for professional (reinsertion. In order to highlight both the opinions and the perceptions of the participants on the labor market, the research had to take place on two levels: among the groups with a difficult position on the labor market and among the employers.

  6. Behavior of adhesion forces of silicone adhesive sealants and mastic butyl under the influence of ionizing radiation

    Adhesives are products that can keep materials together by bonds between the surfaces. Sealants are products that can keep filled a space between two surfaces, through a barrier that is configured as a 'bridge' between the two surfaces. The mastic is a product made of a mixture of substances with the primary butyl polymer, with the consistency of a mass not dried that can be used as a sealant. The polysiloxane, also known as silicone are the most important synthetic polymers with inorganic structure, and are matrices of silicone adhesive sealants. To demonstrate the behavior of the adhesive forces of these products under different conditions, we used five different techniques. These products were subjected to two different conditions to verify the behavior of adhesion, one at the environmental condition and another under the ionizing radiation. The results showed not only differences between products (silicone and mastic), but also that the adhesive forces have different behaviors under the conditions which the samples were subjected. With this was reached the goal of this study that aspired show the differences between the mastic and silicone, this last one is often considered - erroneously - the same as mastic. Thus it was proven that: 1. silicone can be regarded as an adhesive and a sealant at ambient conditions, 2. mastic improves substantially adhesion in an environment of ionizing radiation and this property can be an excellent alternative to the adhesive market.

  2. Differential behavioral effects of the antidepressants reboxetine, fluoxetine, and moclobemide in a modified forced swim test following chronic treatment.

    2005-11-01

    The forced swim test (FST) is the most widely used model for assessing potential antidepressant activity in rodents following acute or short-term treatment. However, few studies have compared the effects of short- and long-term antidepressant treatment on behaviors in the test, despite the need to treat patients chronically to produce clinical effects. The current studies examined whether antidepressants from different classes produce different behavioral effects following short-term treatment and whether such effects change following administration for a longer duration. The effects of administering short-term (3 days) and long-term (14 days) treatments of antidepressants from three different chemical classes with distinct mechanisms of action via osmotic minipump were examined: the selective norepinephrine reuptake inhibitor reboxetine (10 and 60 mg kg(-1) day(-1)), the selective serotonin reuptake inhibitor fluoxetine (2.5 and 15 mg kg(-1) day(-1)), and the reversible inhibitor of monoamine oxidase moclobemide (2.5 and 15 mg kg(-1) day(-1)). All testing was carried out in a 15-min test with no preswim session in order to negate any confounding aspect of an induction procedure. The majority of antidepressant-sensitive behavioral changes were observed in the first 5 min of the test. The low dose of reboxetine failed to alter behavior in the test after 3 days but significantly decreased immobility and increased climbing behavior following administration for 14 days, whereas the high dose of reboxetine was equally effective following 3 and 14 days of treatment. In a similar fashion, the low dose of fluoxetine failed to alter behavior in the test following 3 days, but showed an augmented response on immobility and increased swimming following administration for 14 days. The high dose of fluoxetine was slightly more effective at reducing immobility following administration for 14 days than 3 days. The low dose of moclobemide decreased immobility and increased climbing

    2016-05-01

    Rodents show grooming, a typical self-care behavior, under stress and non-stress conditions. Previous studies revealed that grooming under stress conditions such as the open-field test (OFT) or the elevated plus-maze test (EPM) is associated with anxiety, but the roles of grooming under non-stress conditions are not well understood. Here, we examined spray-induced grooming as a model of grooming under a non-stress condition to investigate the relationship between this grooming and depression-like behavior in the forced swim test (FST) and tail suspension test, and we compared spray-induced grooming with OFT- and EPM-induced grooming. The main finding was that the duration of spray-induced grooming, but not that of OFT/EPM-induced grooming, was negatively correlated with the duration of immobility in the FST, an index of depression-like behavior. The results suggest that spray-induced grooming is functionally different from the grooming in the OFT and EPM and is related to reduction of depressive behavior.

  11. Health sector employment growth calls for improvements in labor productivity.

    Science.gov (United States)

    Hofmarcher, Maria M; Festl, Eva; Bishop-Tarver, Leslie

    2016-08-01

    While rising costs of healthcare have put increased fiscal pressure on public finance, job growth in the health sector has had a stabilizing force on overall employment levels - not least in times of economic crises. In 2014 EU-15 countries employed 21 million people in the health and social care sector. Between 2000 and 2014 the share of employed persons in this sector rose from 9.5% to 12.5% of the total labor force in EU-15 countries. Over time labor input growth has shifted towards residential care activities and social work while labor in human health activities including hospitals and ambulatory care still comprises the major share. About half of the human health labor force works in hospital. Variation of health and social care employment is large even in countries with generally comparable institutional structures. While standard measures of productivity in health and social care are not yet comparable across countries, we argue that labor productivity of a growing health work force needs more attention. The long-term stability of the health system will require care delivery models that better utilize a growing health work force in concert with smart investments in digital infrastructure to support this transition. In light of this, more research is needed to explain variations in health and social care labor endowments, to identify effective policy measures of labor productivity enhancement including enhanced efforts to develop comparable productivity indicators in these areas.

  12. Repeated exposure to corticosterone increases depression-like behavior in two different versions of the forced swim test without altering nonspecific locomotor activity or muscle strength.

    Science.gov (United States)

    Marks, Wendie; Fournier, Neil M; Kalynchuk, Lisa E

    2009-08-04

    We have recently shown that repeated high dose injections of corticosterone (CORT) reliably increase depression-like behavior on a modified one-day version of the forced swim test. The main purpose of this experiment was to compare the effect of these CORT injections on our one-day version of the forced swim test and the more traditional two-day version of the test. A second purpose was to determine whether altered behavior in the forced swim test could be due to nonspecific changes in locomotor activity or muscle strength. Separate groups of rats received a high dose CORT injection (40 mg/kg) or a vehicle injection once per day for 21 consecutive days. Then, half the rats from each group were exposed to the traditional two-day forced swim test and the other half were exposed to our one-day forced swim test. After the forced swim testing, all the rats were tested in an open field and in a wire suspension grip strength test. The CORT injections significantly increased the time spent immobile and decreased the time spent swimming in both versions of the forced swim test. However, they had no significant effect on activity in the open field or grip strength in the wire suspension test. These results show that repeated CORT injections increase depression-like behavior regardless of the specific parameters of forced swim testing, and that these effects are independent of changes in locomotor activity or muscle strength.

    Highlights: • Transient- and steady-state hydrogen permeation from Li-Pb forced convection flow through permeable tube to outside Ar purge gas was investigated at 600 °C. • It was found that the overall permeation rates were limited by diffusion in the Li-Pb boundary layer developed from the flow inlet. • The effect of the boundary layer was correlated in terms of mass transfer coefficient. The values of mass transfer coefficients at 600 °C were compared with those of 400 °C and 500 °C obtained beforehand. - Abstract: Transient- and steady-state hydrogen permeation from Li-Pb forced convection flow in a permeable tube to outside Ar purge gas was investigated between 400–600 °C. The values of the steady-state permeation rate increased with the increase of the Li-Pb flow rate. It was found that the overall permeation rates were limited by diffusion in a Li-Pb boundary layer developed from flow inlet. The effect of the boundary layer was correlated in terms of the mass-transfer coefficient. The values of the mass-transfer coefficient at 600 °C were compared with those of 400 °C and 500 °C obtained beforehand. Judged from these data of mass-transfer coefficients, it can be predicted that the effect of boundary layer varies with the increase of Li-Pb flow rate at different temperature conditions.

    Background Naturalistic driving studies, designed to objectively assess driving behavior and outcomes, are conducted by equipping vehicles with dedicated instrumentation (eg, accelerometers, gyroscopes, Global Positioning System, and cameras) that provide continuous recording of acceleration, location, videos, and still images for eventual retrieval and analyses. However, this research is limited by several factors: the cost of equipment installation; management and storage of the large amounts of data collected; and data reduction, coding, and analyses. Modern smartphone technology includes accelerometers built into phones, and the vast, global proliferation of smartphones could provide a possible low-cost alternative for assessing kinematic risky driving. Objective We evaluated an in-house developed iPhone app (gForce) for detecting elevated g-force events by comparing the iPhone linear acceleration measurements with corresponding acceleration measurements obtained with both a custom Android app and the in-vehicle miniDAS data acquisition system (DAS; Virginia Tech Transportation Institute). Methods The iPhone and Android devices were dashboard-mounted in a vehicle equipped with the DAS instrumentation. The experimental protocol consisted of driving maneuvers on a test track, such as cornering, braking, and turning that were performed at different acceleration levels (ie, mild, moderate, or hard). The iPhone gForce app recorded linear acceleration (ie, gravity-corrected). The Android app recorded gravity-corrected and uncorrected acceleration measurements, and the DAS device recorded gravity-uncorrected acceleration measurements. Lateral and longitudinal acceleration measures were compared. Results The correlation coefficients between the iPhone and DAS acceleration measurements were slightly lower compared to the correlation coefficients between the Android and DAS, possibly due to the gravity correction on the iPhone. Averaging the correlation coefficients for

    On September 30, 1990, the first World Summit for Children promised to reduce child mortality and malnutrition. It set targets to be reached by the year 2000. Although it established no explicit goals on child labor, the targets included basic education for all children and the completion of primary education by at least 80 percent of children. Meeting these goals will reduce child labor, say the authors. The evidence they review shows that education intervention play a key role in reducing c...

    Eighty three primigravidae patients at the end of latency labor, erased cervix, 3 cm dilation, vertex presentation and adequate pelvis, were studied. Two groups were formed: 53 patients in the study group, who received active management of labor, and 30 patients in the control group, treated in the traditional way. In all the patients a graphic recording of labor, was carried out; it included all the events, and as labor advanced, a signoidal curve of cervical dilatation, was registered, as well as the hyperbolic one for presentation descent. The study group received the method in a systematized manner, as follows: 1. Peridular block. 2. Amniotomy. 3. IV oxytocin one hour after amniotomy. 4. FCR monitoring. 5. Detection of dystocia origin. Materno-fetal morbidity was registered in both groups, as well as cesarean section rate, instrumental delivery and its indications, labor duration, and time of stay in labor room. Diminution of above intems and opportune detection of dystocia, were determined. It was concluded that a constructive action plan, starting at hospital admission in most healthy women, allows a normal delivery of brief duration.

    The authors present a case for including the patriarchal model into the analysis of female labor force participation in the United States. They argue that only if it is assumed that the division of labor and distribution of goods and services are structured to benefit the male head of the family can various trends be explained, including the low relative income of women compared to men, the increase in female labor force participation without a corresponding increase in household work by men, and the increasing number of divorces initiated by women despite the fact that divorce increases female poverty.

  3. Dialética do desenvolvimento periférico: dependência, superexploração da força de trabalho e política econômica Dialectics of peripheral development: dependence, superexploitation of labor force and economic policy

    Full Text Available Este trabalho procura discutir as possibilidades de desenvolvimento na periferia da economia mundial, enfatizando dois aspectos. Em primeiro lugar, observa-se que as políticas econômicas neoliberais e a reestruturação produtiva foram formas encontradas pelo capital para responder à sua própria crise dos anos 1970, e que essas formas aprofundaram a condição de dependência das economias periféricas dentro da lógica mundial de acumulação capitalista. Em segundo lugar, constata-se que a única maneira de desenvolvimento capitalista na periferia, tendo em vista o aprofundamento da dependência, é a superexploração da força de trabalho. Por fim, argumenta-se que as alternativas para a periferia passam pela redução dessa superexploração da força de trabalho e/ou da luta contra a própria exploração capitalista da força de trabalho como forma de extração de excedente.This paper aims to discuss the possibilities of development in the periphery of the world economy emphasizing two points. Firstly, there is that the neoliberal economic policies and productive restructuring were forms found by capital to respond to its own crisis of 70's, and that these forms deepened the condition of dependency of peripheral economies within the logic of global capitalist accumulation. Secondly, it appears that the only way of capitalist development in the periphery, with a view to deepening dependence, is the superexploitation of labor force. Finally, it is argued that the alternatives to the periphery are the reduction of superexploitation of labor force and/or the fight against the capitalist exploitation of the labor force as a form of extraction of surplus.

    Semi-quartic force fields (QFF) rely on a Taylor-expansion of the multi-dimensional Born-Oppenheimer potential energy surface (PES) and are frequently used within the calculation of anharmonic vibrational frequencies based on 2nd order vibrational perturbation theory (VPT2). As such they are usually determined by differentiation of the electronic energy with respect to the nuclear coordinates. Alternatively, potential energy surfaces can be expanded in terms of multi-mode expansions, which typically do not require any derivative techniques. The computational effort to retrieve QFF from size-reduced multi-mode expansions has been studied and has been compared with standard Taylor-expansions. As multi-mode expansions allow for the convenient introduction of subtle approximations, these will be discussed in some detail. In addition, a preliminary study about the applicability of a generalized Duschinsky transformation to QFFs is provided. This transformation allows for the efficient evaluation of VPT2 frequencies of isotopologues from the PES of the parent compound and thus avoids the recalculation of PESs in different axes systems.

  8. Analytical study on thermal-hydraulic behavior of transient from forced circulation to natural circulation in JRR-3

    International Nuclear Information System (INIS)

    Hirano, Masashi; Sudo, Yukio

    1986-01-01

    Transient thermal-hydraulic behaviors of the JRR-3 which is an open-pool type research reactor has been analyzed with the THYDE-P1 code. The focal point is the thermal-hydraulic behaviors related to the core flow reversal during the transition from forced circulation downflow to natural circulation upflow. In the case of a loss-of-coolant accident (LOCA), for example, the core flow reversal is expected to occur just after the water pool isolation from the primary cooling loop with a leak. The core flow reversal should cause a sudden increase in fuel temperature and a steep decrease in the departure-from-nucleate-boiling ratio (DNBR) and the phenomenon is, therefore, very important especially for safety design and evaluation of research reactors. Major purposes of the present work are to clarify physical phenomena during the transient and to identify important parameters affecting the peak fuel temperature and the minimum DNBR. The results calculated with THYDE-P1 assuming the sequences of events of the loss-of-offsite power and LOCA help us to understand the phenomena both qualitatively and quantitatively, with respect to the safety design and evaluation.

    2017-04-01

    To describe the stretch-shortening behavior of ankle plantar-flexing muscle-tendon units (MTUs) during the push-off in a sprint start. Fifty-four male (100-m personal best: 9.58-12.07 s) and 34 female (100-m personal best: 11.05-14.00 s) sprinters were analyzed using an instrumented starting block and 2-dimensional high-speed video imaging. Analysis was performed separately for front and rear legs, while accounting for block obliquities and performance levels. The results showed clear signs of a dorsiflexion in the upper ankle joint (front block 15.8° ± 7.4°, 95% CI 13.2-18.2°; rear block 8.0° ± 5.7°, 95% CI 6.4-9.7°) preceding plantar flexion. When observed in their natural block settings, the athletes' block obliquity did not significantly affect push-off characteristics. It seems that the stretch-shortening-cycle-like motion of the soleus MTU has an enhancing influence on push-off force generation. This study provides the first systematic observation of ankle-joint stretch-shortening behavior for sprinters of a wide range of performance levels. The findings highlight the importance of reactive-type training for the improvement of starting performance. Nonetheless, future studies need to resolve the independent contributions of tendinous and muscle-fascicle structures to overall MTU performance.

    Environmental factors play a key role in the etiology of depression. The rodent forced swim test (FST) is commonly used as a preclinical model of depression, with increases in escape-directed behavior reflecting antidepressant effects, and increases in immobility reflecting behavioral despair. Environmental enrichment leads to serotonergic alterations in rats, but it is unknown whether these alterations may influence the efficacy of common antidepressants. Male Sprague-Dawley rats were reared in enriched (EC), standard (SC), or isolated (IC) conditions. Following the rearing period, fluoxetine (10 or 20 mg/kg, i.p.) was administered 23.5 hrs, 5 hrs, and 1 hr before locomotor and FST measures. Following locomotor testing and FST exposure, rats were weighed to assess fluoxetine-, FST-, and environmental condition-induced moderations in weight gain. Results revealed an antidepressant effect of environmental enrichment and a depressant effect of isolation. Regardless of significant fluoxetine effects on locomotor activity, fluoxetine generally decreased swimming and increased immobility in all three environmental conditions, with IC-fluoxetine (10 mg/kg) rats and EC-fluoxetine (20 mg/kg) rats swimming less than vehicle counterparts. Subchronic 20 mg/kg fluoxetine also induced significant weight loss, and differential rearing appeared to moderate weight gain following FST stress. These results suggest that differential rearing has the ability to alter FST behaviors, fluoxetine efficacy, and post-stressor well-being. Moreover, 20 mg/kg fluoxetine, administered subchronically, may lead to atypical effects of those commonly observed in the FST, highlighting the importance and impact of both environmental condition and dosing regimen in common animal models of depression.

    Repeated forced swimming test (rFST) may detect gradual effects of antidepressants in adult rats. Antidepressants, as enrichment, affected behavior and neurogenesis in rats. However, the influence of enrichment on behavioral and neurogenic effects of antidepressants is unknown. Here, effects of antidepressants on rFST and hippocampal neurogenesis were investigated in rats under enriched conditions. Behaviors of male Wistar rats, housed from weaning in standard (SE) or enriched environment (EE), were registered during rFST. The rFST consisted of 15min of swimming (pretest) followed by 5min of swimming in the first (test), seventh (retest 1) and fourteenth (retest 2) days after pretest. One hour before the test, rats received an intraperitoneal injection of saline (1ml/kg), fluoxetine (2.5mg/kg) or imipramine (2.5 or 5mg/kg). These treatments were performed daily until the day of the retest 2. After retest 2, rats were euthanized for the identification of markers for neurogenesis in the hippocampus. Fluoxetine or imipramine decreased immobility in retests 1 and 2, as compared to saline. EE abolished these differences. In EE, fluoxetine or imipramine (5mg/kg) reduced immobility time in retest 2, as compared to the test. Independent of the housing conditions, fluoxetine and imipramine (5mg/kg) increased the ratio of immature neurons per progenitor cell in the hippocampus. In summary, antidepressants or enrichment counteracted the high immobility in rFST. Enrichment changed the effects of antidepressants in rFST depending on the type, and the dose of a substance but failed to change neurogenesis in control or antidepressant treated-rats. Effects of antidepressants and enrichment on rFST seemed neurogenesis-independent. Copyright © 2014 Elsevier Inc. All rights reserved.

    Naturalistic driving studies, designed to objectively assess driving behavior and outcomes, are conducted by equipping vehicles with dedicated instrumentation (eg, accelerometers, gyroscopes, Global Positioning System, and cameras) that provide continuous recording of acceleration, location, videos, and still images for eventual retrieval and analyses. However, this research is limited by several factors: the cost of equipment installation; management and storage of the large amounts of data collected; and data reduction, coding, and analyses. Modern smartphone technology includes accelerometers built into phones, and the vast, global proliferation of smartphones could provide a possible low-cost alternative for assessing kinematic risky driving. We evaluated an in-house developed iPhone app (gForce) for detecting elevated g-force events by comparing the iPhone linear acceleration measurements with corresponding acceleration measurements obtained with both a custom Android app and the in-vehicle miniDAS data acquisition system (DAS; Virginia Tech Transportation Institute). The iPhone and Android devices were dashboard-mounted in a vehicle equipped with the DAS instrumentation. The experimental protocol consisted of driving maneuvers on a test track, such as cornering, braking, and turning that were performed at different acceleration levels (ie, mild, moderate, or hard). The iPhone gForce app recorded linear acceleration (ie, gravity-corrected). The Android app recorded gravity-corrected and uncorrected acceleration measurements, and the DAS device recorded gravity-uncorrected acceleration measurements. Lateral and longitudinal acceleration measures were compared. The correlation coefficients between the iPhone and DAS acceleration measurements were slightly lower compared to the correlation coefficients between the Android and DAS, possibly due to the gravity correction on the iPhone. Averaging the correlation coefficients for all maneuvers, the longitudinal and

    Disability Insurance (DI) is a public program that provides income support to persons unable to continue work due to disability. The difficulty of defining disability, however, has raised the possibility that this program may be subsidizing the early retirement of workers who are not truly disabled. A critical input for assessing the optimal size of the DI program is therefore the elasticity of labor force participation with respect to benefits generosity. Unfortunately, this parameter has be...

    2014-06-01

    This article borrows from the intersectionality literature to investigate how legal status, labor market position, and family characteristics structure the labor supply of immigrant Latinas in Durham, NC, a new immigrant destination. The analysis takes a broad view of labor force participation, analyzing the predictors of whether or not women work; whether and how the barriers to work vary across occupations; and variation in hours and weeks worked among the employed. I also explicitly investigate the extent to which family constraints interact with other social characteristics, especially legal status, in shaping women's labor market position. Results highlight that immigrant Latinas experience multiple, interrelated constraints on employment owing to their position as low-skill workers in a labor market highly segregated by gender and nativity, to their status as members of a largely undocumented population, and as wives and mothers in an environment characterized by significant work-family conflict.

    Full Text Available Labor discrimination is a phenomenon with very serious social and economic consequences, which has increased actuality and importance in Bulgaria nowadays. Because of the high price of discrimination, building effective anti-discrimination legislation occupies a special place in the policy of the European Union. Despite the European directives, the presence of anti-discrimination legislation and the broadly declared anti-discrimination inclinations in our country, these are absolutely not enough for providing environment of equality, with a climate of respect and tolerance to the differences. It turns out that certain groups are definitely victims of labor discrimination. In this connection the present article consecutively identifies these groups, as well as the reasons for their discrimination, underlining the necessity and benefits of the integration of the different.

    The increasing costs and schedule delays being experienced in construction projects have led companies to look for alternatives to their present methods of expansion. One of the facets being evaluated is the construction labor posture. As a result, more companies are employing open shop contractors. Certain benefits can be realized by open shop construction. Productivity, in terms of the time required and overall costs, is definitely improved at no sacrifice in quality. Before an owner decides to build a project open shop, however, he must be fully aware of the pro's and con's of both types of labor posture. He must know to select a capable open shop contractor and he must realize his obligations for a successful open shop program

    The first assignment of DNA polymerases at the eukaryotic replication fork was possible after the in vitro reconstitution of the simian virus 40 (SV40) replication system. In this system, DNA polymerase α (Pol α) provides both leading and lagging strands with RNA-DNA primers that are extended by DNA polymerase δ (Pol δ). Extrapolating the architecture of the replication fork from the SV40 model system to an actual eukaryotic cell has been challenged by the discovery of a third DNA polymerase in Saccharomyces cerevisiae, DNA polymerase ε (Pol ε). A division of labor has been proposed for the eukaryotic replication fork whereby Pol ε replicates the leading strand and Pol δ replicates the lagging strand. However, an alternative model of unequal division of labor in which Pol δ can still participate in leading-strand synthesis is plausible.

    2016-04-01

    Full Text Available The article examines the main causes of labor informality in order to verify the validity of classical theories that explain unemployment in market economies and its relationship to informality. Methodologically, the project was based, in the empirical part, on international statistics, comparing the evolution of labor market structure in a combined sample of highly industrialized countries and other less industrialized ones. Empirical evidence supports the conclusion that the classical economic theory of Marxist origin is inefficient to explain the causes of unemployment in contemporary market economies, as well as it fails to satisfactorily explain informality. On the contrary, we conclude that the theory in question is more relevant to explain informality in centrally planned economies where this phenomenon has been present even more significantly than in free market economies.

    A common biological pathway may contribute to the comorbidity of atherosclerosis and depression. Increased activity of the enzymatic 5-lipoxygenase (5-LOX; 5LO) pathway is a contributing factor in atherosclerosis and a 5-LOX inhibitor, MK-886, is beneficial in animal models of atherosclerosis. In the brain, MK-886 increases phosphorylation of the glutamate receptor subunit GluR1, and the increased phosphorylation of this receptor has been associated with antidepressant treatment. In this work, we evaluated the behavioral effects of MK-886 in an automated assay of mouse forced swimming, which identifies antidepressant activity as increased climbing behavior and/or decreased rest time. Whereas a single injection of MK-886 (3 and 10 mg/kg) did not affect forced swimming behaviors assayed 30 min later, 6 daily injections of 3 mg/kg MK-886 slightly increased climbing and significantly reduced rest time in wild-type mice but not in 5-LOX-deficient mice. A diet delivery of MK-886, 4 μg per 100 mg body-weight per day, required three weeks to affect forced swimming; it increased climbing behavior. Climbing behavior was also increased in naive 5-LOX-deficient mice compared to naive wild-type controls. These results suggest that 5-LOX inhibition and deficiency may be associated with antidepressant activity. Increased climbing in a forced swimming assay is a typical outcome of antidepressants that increase noradrenergic and dopaminergic activity. Interestingly, 5-LOX deficiency and MK-886 treatment have been shown to be capable of increasing the behavioral effects of a noradrenaline/dopamine-potentiating drug, cocaine. Future research is needed to evaluate the clinical relevance of our findings. PMID:18403121

    Bettio, Luis E B; Freitas, Andiara E; Neis, Vivian B; Santos, Danúbia B; Ribeiro, Camille M; Rosa, Priscila B; Farina, Marcelo; Rodrigues, Ana Lúcia S

    Guanosine is a guanine-based purine that modulates glutamate uptake and exerts neurotrophic and neuroprotective effects. In a previous study, our group demonstrated that this endogenous nucleoside displays antidepressant-like properties in a predictive animal model. Based on the role of oxidative stress in modulating depressive disorders as well as on the association between the neuroprotective and antioxidant properties of guanosine, here we investigated if its antidepressant-like effect is accompanied by a modulation of hippocampal oxidant/antioxidant parameters. Adult Swiss mice were submitted to an acute restraint stress protocol, which is known to cause behavioral changes that are associated with neuronal oxidative damage. Animals submitted to ARS exhibited an increased immobility time in the forced swimming test (FST) and the administration of guanosine (5mg/kg, p.o.) or fluoxetine (10mg/kg, p.o., positive control) before the exposure to stressor prevented this alteration. Moreover, the significantly increased levels of hippocampal malondialdehyde (MDA; an indicator of lipid peroxidation), induced by ARS were not observed in stressed mice treated with guanosine. Although no changes were found in the hippocampal levels of reduced glutathione (GSH), the group submitted to ARS procedure presented enhanced glutathione peroxidase (GPx), glutathione reductase (GR), superoxide dismutase (SOD) activities and reduced catalase (CAT) activity in the hippocampus. Guanosine was able to prevent the alterations in GPx, GR, CAT activities, and in SOD/CAT activity ratio, but potentiated the increase in SOD activity elicited by ARS. Altogether, the present findings indicate that the observed antidepressant-like effects of guanosine might be related, at least in part, to its capability of modulating antioxidant defenses and mitigating hippocampal oxidative damage induced by ARS.

  2. ROLE AND CONSEQUENCES OF EMOTIONAL LABOR IN THE WORKPLACE

    Directory of Open Access Journals (Sweden)

    Andreea Fortuna SCHIOPU

    2014-06-01

    Full Text Available The use of emotions in the workplace has begun to be increasingly studied by theorists and researchers in organizational behavior. One essential construct in the literature is the emotional labor which is perceived to be the management of feelings to express organizationally desired emotions. This article aims to review existing perspectives on emotional labor, to differentiate the concepts of emotional labor and emotional dissonance, to analyze emotion regulation strategies, and to discuss the consequences of emotional labor in the workplace. These clarifications with regard to the emotional labor and its mechanisms can help manage their associated negative outcomes (such as emotional exhaustion, lower job satisfaction, higher levels of burnout, and intentions to quit the job and sustain their possible positive outcomes (such as feelings of accomplishment and enhanced identification with the work role.

    This study contributed to a better understanding of the behavior of nanoparticles (NPs) in dynamic water. First, the aggregation behavior of CeO{sub 2} NPs at different pH values in various salt solutions was examined to determine the appropriate hydrochemical conditions for hydrodynamics study. Second, the aggregation behavior of CeO{sub 2} NPs under different shear forces was investigated at pH 4 and ionic strength 0 in various salt solutions to find out whether shear forces could influence the stability of the nanoparticles and if yes, how. Also, five-stage sedimentation tests were conducted to understand the influence of shear stress on the vertical distribution of CeO{sub 2} NPs in natural waters. The aggregation test showed that the shear force could increase the collision efficiency between NPs during aggregation and cause a relatively large mass of NPs to remain in suspension. Consequently, the nanoparticles had a greater possibility of continued aggregation. The sedimentation test under static conditions indicated that a large mass of NPs (>1000 nm) sink to the bottom layer, leaving only small aggregates dispersed in the upper or middle layer of the solution. However, later sedimentation studies under stirring conditions demonstrated that shear forces can disrupt this stratification phenomenon. These results suggest that shear forces can influence the spatial distribution of NPs in natural waters, which might lead to different toxicities of CeO{sub 2} NPs to aquatic organisms distributed in the different water layers. This study contributes to a better understanding of nanomaterial toxicology and provides a way for further research.Graphical Abstract.

    2015-11-01

    Behavioral testing of mouse models of Huntington's disease (HD) is a key component of preclinical assessment for potential pharmacological intervention. An open field with a force plate floor was used to quantify numerous spontaneous behaviors in a slowly progressing model of HD. CAG140 (+/+, +/-, -/-) male and female mice were compared in a longitudinal study from 6 to 65 weeks of age. Distance traveled, wall rears, wall rear duration, number of low mobility bouts, in-place movements, number of high velocity runs, and gait parameters (stride rate, stride length, and velocity) were extracted from the ground reaction forces recorded in 20-min actometer sessions. Beginning at 11 weeks, HD mice (both +/- and +/+) were consistently hypoactive throughout testing. Robust hypoactivity at 39 weeks of age was not accompanied by gait disturbances. By 52 and 65 weeks of age the duration of wall rears increased and in-place tremor-like movements emerged at 65 weeks of age in the +/+, but not in the +/- HD mice. Taken together, these results suggest that hypoactivity preceding frank motor dysfunction is a characteristic of CAG140 mice that may correspond to low motivation to move seen clinically in the premanifest/prediagnostic stage in human HD. The results also show that the force plate method provides a means for tracking the progression of behavioral dysfunction in HD mice beyond the stage when locomotion is lost while enabling quantification of tremor-like and similar in-place behaviors without a change in instrumentation. Use of force plate actometry also minimizes testing-induced enrichment effects when batteries of different tests are carried out longitudinally. Copyright © 2015 Elsevier B.V. All rights reserved.

    Iulia BĂDOI

    2014-06-01

    Full Text Available Negotiation is the process we use in order to obtain things that we want and are controlled by others. Any desire we intend to fulfill, any need that we are obliged to meet is a potential bargaining situations. Between groups and individuals, negotiation occurs naturally, as some have one thing that the other wants and is willing to bargain to get it. More or less we are all involved in negotiations: closing a contract, buying a thing, obtaining sponsorships, collective decision making, conflict resolution, agreement on work plans. Within the field of labor relations, negotiation can occur on the occasion of closing / amending employment contracts or in order to regulate employment or work relations. Moreover, used properly, the negotiation can be an effective tool for solving labor disputes, with benefits for both involved parties. This paper aims to present negotiating principles and steps to follow in planning and preparing negotiations and the negotiating techniques that can lead to a successful negotiation based on a well-developed plan.

  10. Evolutionary dynamics of division of labor games with selfish agents

    Science.gov (United States)

    Zhang, Jianlei; Li, Qiaoyu; Zhang, Chunyan

    2017-11-01

    The division of labor is one of the most basic and widely studied aspects of collective behavior in natural systems. Studies of division of labor are concerned with the integration of the individual worker behavior into a colony level task organization and with the question of how the regulation of the division of labor may contribute to the colony efficiency. This paper investigates the evolution of the division of labor with three strategies by employing the evolutionary game theory. Thus, these available strategies are, respectively, strategy A (performing task A), strategy B (performing task B), and strategy D (not performing any task but only free riding others' contributions). And, two typical networks (i.e., BA scale-free network and lattice network) are employed here for describing the interaction structure among agents. The theoretical analysis together with simulation results reveal that the division of labor can evolve and leads to players that differ in their tendency to take on a given task. The conditions under which the division of labor evolves depend on the costs for performing the task, the benefits led by performing the task, and the interaction structures among the players who are involved with division of labor games.

    Full Text Available This paper aims to highlight some often occurring failures that need to be eliminated when attempting to develop an integral and efficient policy on labor migration. As an example, a brief overview of the development of immigration policies and its critical shortcomings in the Czech Republic is provided. Following this, the paper analyzes two aspects: the protection of migrant workers and the trafficking in human beings. In particular, the paper deals with three crucial issues of labor migration which are: (1 the inconsistent aims of immigration policies, (2 the client system, and (3 the dependence on middlemen. The paper also focuses on the role of state, police, and NGO’s in the trafficking in human beings and forced labor or labor exploitation in the Czech Republic. In addition, the legislation on forced labor and the possibilities of assistance to trafficked person are analyzed.By comparing various aspects of immigration policy, this paper covers some, but certainly not all, of the key issues concerning the process of immigrant integration. Several suggestions are made that could improve the situation of labor migrants in a significant way.

    Despite the existence of laws in India that prohibit the labor of children under age 14, 70 to 115 million children between the ages of 5 and 14 are estimated to be part of India's labor force. Child labor in the agriculture sector accounts for 80% of child laborers in India and 70% of working children globally. From May 2001 to July 2001, Physicians for Human Rights (PHR) investigated the health experiences of 100 children in hybrid cottonseed production in rural Andhra Pradesh. Eighty-eight percent of the survey participants were girls, ages 7 to 14. PHR found that children worked on average 12 hours a day, were frequently exposed to pesticides, and were not provided with safety equipment, not even shoes or water to wash their hands and clothes. Children reported having frequent headaches and dizziness and skin and eye irritations after pesticide spraying. All 100 children reported that they were unable to go to school during the hybrid cottonseed season due to work demands. Ninety-four children reported to PHR that they would rather be in school. In addition, a majority of child workers interviewed by PHR reported physical and/or verbal abuse by their employers. Moreover, PHR interviews with representatives of multinational and national companies revealed knowledge of child labor practices for up to 10 years. Child labor is a significant health and human rights problem for children in India. The progressive elimination of child labor practices will require the support of a wide cross-section of civil society.

    Full Text Available Generally, an activity is considered to be efficient if the production implies low costs or if the revenues from selling the products on the market outweigh the expenditures that were made to achieve them. Labor productivity as an efficiency indicator of a production process represents an expression of the relationship between effect (products, services and effort (work means, labor force, work items. Through the labor productivity conversion in rates of return (economic and commercial is determined an evolution and an influence on these rates, driving the company’s own efforts to innovate, produce and harness goods, works and services with maximum utility, efficiency and competitiveness services. The aim of this paper is to highlight the work efficiency, respectively the labor productivity detached from the factorial context in the trade and economic rates of return. The introduction presents some general aspects referring to labor productivity, then it will be presented and discussed the analytical methods used in the process of reflecting the labor productivity in the rates of return, the results analysis, and at the end of this paper it will be presented some conclusions based on the study case. The expected results consist in identifying the mechanisms by which labor efficiency is converted into the company’s economic and financial performance.

  1. Child labor in the US

    Directory of Open Access Journals (Sweden)

    Wegmann David

    2003-01-01

    Full Text Available This paper presents a report on child labor in the U.S. that reviewed the positive and negative aspects of work for youth. Working was found to provide young people with valuable lessons about responsibility, punctuality, interacting with people and learning about money management, increasing self-esteem and helping them become independent and skilled. Research findings suggested that working during high school may contribute to increased rates of employment and better wages up to a decade after high school completion. Research concerning the hazards associated with work indicated that, each year, tens of thousands of young people are seen in hospital emergency departments for work-related injuries, hundreds require hospitalization, and more than 70 die of work-related injuries. Long work hours during the school year were associated with problem behaviors. The report points out some important questions: updating regulations on allowable work hours, eliminating less stringent regulation of agricultural work, revising outdated rules against hazardous work, developing and implementing a comprehensive plan for monitoring the injuries, illnesses, and hazards, building workplace health and safety information into school-based programs, and developing criteria for designating "commendable workplaces for youth."

    To assess health service costs associated with labor induction according to different clinical situations in a tertiary-level hospital. In a prospective study, individual patient cost data were assessed for women admitted for induction of labor at a tertiary hospital in Spain between November 1, 2012, and August 31, 2013. The costs of labor induction were estimated according to maternal and neonatal outcomes, method of delivery, cervical condition at admission, and obstetric indication. Direct costs including professional fees, epidural, maternal stay, consumables, and drugs were calculated. Overall, 412 women were included in the final cost analysis. The mean total cost of labor induction was €3589.87 (95% confidence interval [CI] 3475.13-3704.61). Cesarean delivery after labor induction (€4830.45, 95% CI 4623.13-5037.58) was significantly more expensive than spontaneous delivery (€3037.45, 95% CI 2966.91-3179.99) and instrumental vaginal delivery (€3344.31, 95%CI 3151.69-3536.93).

    2013-08-06

    Update of the 2004 U.S. Preventive Services Task Force (USPSTF) recommendation statement on screening and behavioral counseling interventions in primary care to reduce alcohol misuse. The USPSTF reviewed new evidence on the effectiveness of screening for alcohol misuse for improving health outcomes, the accuracy of various screening approaches, the effectiveness of various behavioral counseling interventions for improving intermediate or long-term health outcomes, the harms of screening and behavioral counseling interventions, and influences from the health care system that promote or detract from effective screening and counseling interventions for alcohol misuse. These recommendations apply to adolescents aged 12 to 17 years and adults aged 18 years or older. These recommendations do not apply to persons who are actively seeking evaluation or treatment of alcohol misuse. The USPSTF recommends that clinicians screen adults aged 18 years or older for alcohol misuse and provide persons engaged in risky or hazardous drinking with brief behavioral counseling interventions to reduce alcohol misuse. (Grade B recommendation)The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening and behavioral counseling interventions in primary care settings to reduce alcohol misuse in adolescents.

  19. A cross-bridge based model of force depression: Can a single modification address both transient and steady-state behaviors?

    Science.gov (United States)

    Corr, David T; Herzog, Walter

    2016-03-21

    Force depression (FD), the reduction of isometric force following active shortening, is a phenomenon of skeletal muscle that has received significant attention in biomechanical and physiological literature, yet the mechanisms underlying FD remain unknown. Recent experiments identified a slower rate of force redevelopment with increasing amounts of steady-state FD, suggesting that FD may be caused, at least in part, by a decrease in cross-bridge binding rate (Corr and Herzog, 2005; Koppes et al., 2014). Herein, we develop a cross-bridge based model of FD in which the binding rate function, f, decreases with the mechanical work performed during shortening. This modification incorporates a direct relationship between steady-state FD and muscle mechanical work (Corr and Herzog, 2005; Herzog et al., 2000; Kosterina et al., 2008), and is consistent with a proposed mechanism attributing FD to stress-induced inhibition of cross-bridge attachments (Herzog, 1998; Maréchal and Plaghki, 1979). Thus, for an increase in mechanical work, the model should predict a slower force redevelopment (decreased attachment rate) to a more depressed steady-state force (fewer attached cross-bridges), and a reduction in contractile element stiffness (Ford et al., 1981). We hypothesized that since this modification affects the cross-bridge kinetics, a corresponding model would be able to account for both transient and steady-state FD behaviors. Comparisons to prior experiments (Corr and Herzog, 2005; Herzog et al., 2000; Kosterina et al., 2008) show that both steady-state and transient aspects of FD, as well as the relationship of FD with respect to speed and amplitude of shortening, are well captured by this model. Thus, this relatively simple cross-bridge based model of FD lends support to a mechanism involving the inhibition of cross-bridge binding, and indicates that cross-bridge kinetics may play a critical role in FD.

    Full Text Available The present study aims to analyze the influence of motivation on human talent and determine the factors that have the greatest impact on work performance. The research was developed on the basis of a hermeneutic methodology, which began in the bibliographical-documentary revision allowing to obtain the theoretical references, basic and relevant criteria about the labor motivation, in such a way that the obtaining, identification and description of the data facilitated the achievement of the objective set, resulting in a motivated employee to provide the company with a better performance, develop a sense of belonging, fidelity to what it does, reflecting as a consequence benefits for both the company and employees concluding that the behavior of an employee in the organization, depends on the motivational factors that are applied in order to satisfy their basic needs such as good labor relations, job satisfaction, positive working environment and the results of job satisfaction; nowadays, motivating rightly has become an activity that will get employees to create a sense of belonging and the activity that each of them perform, yield positive results in order to contribute successfully in what the organization does. As a fundamental element in the assertive development of the organization, motivation is closely related to job satisfaction, labor relations and the work environment, without neglecting the role of the manager who plays a special role, at the time of carrying the responsibility and apply the most appropriate strategies of motivation within a business organization.

    2018-01-01

    Full Text Available This is an empirical investigation of the homogeneity of gender disaggregated labor using the Douglas, single/multi-factor translog production functions; and labor productivity functions for the USA.   The results based on the single factor translog model, indicated that: an increase in the capita/female labor ratio increases aggregate output; male labor is more productive than female labor, which is more productive than capital; a simultaneous increase in quantity allocated and productivity of the leads to an increase in output; female labor productivity has grown slower than male labor productivity; it much easier to substitute male labor for capital compared to female labor; and the three inputs are neither perfect substitutes nor perfect complements. As a consequence, male and female labor are not homogenous inputs. Efforts to investigate the factors influencing gender disaggregated labor productivity; and designing policies to achieve gender parity in numbers/productivity in the labor force and increasing the ease of substitutability between male labor and female labor are required.

    2016-09-01

    Full Text Available Background: The female labor force participation rate in China has experienced a significant decline over the past two decades. Existing studies attribute this decline to the retreat of government protection of female employment and growing gender discrimination in the labor market, while overlooking other factors such as changing living arrangements. Objective: This paper aims to explore the causal effect of coresidence or nearby residence with parents on female labor supply in China. Methods: Based on a paired sample of middle-aged married women and their elderly parents, we apply the instrumental variable approach to correct for the endogeneity of living arrangement. Results: We show that women coresiding with their parents are 27.9 percentage points more likely to work than those living apart, and women living with their parents in the same neighborhood are 34.9 percentage points more likely to work than those living in a different neighborhood. Also, on average, coresidence or nearby residence with parents significantly increases women's work time by 20-26 hours per week. The positive impacts of this living arrangement are more prominent in urban areas than in rural areas. We also show that intergenerational coresidence allows women to share the burden of housework with their parents, thus leading to increased labor supply. Conclusions: Our study offers a fresh explanation for the drop in female labor force participation in China since 1990. Policies directed towards encouraging intergenerational coresidence would be effective in improving female labor supply. Contribution: This paper brings new evidence on the causal relationship between living arrangement and female labor supply in China.

  4. On the dynamic fracture toughness and crack tip strain behavior of nuclear pressure vessel steel: Application of electromagnetic force

    International Nuclear Information System (INIS)

    Yagawa, G.; Yoshimura, S.

    1986-01-01

    This paper is concerned with the application of the electromagnetic force to the determination of the dynamic fracture toughness of materials. Taken is an edge-cracked specimen which carries a transient electric current and is simply supported in a steady magnetic field. As a result of their interaction, the dynamic electromagnetic force occurs in the whole body of the specimen, which is then deformed to fracture in the opening mode of cracking. Using the electric potential and the J-R curve methods to determine the dynamic crack initiation point in the experiment, together with the finite element method to calculate the extended J-integral with the effects of the electromagnetic force and inertia, the dynamic fracture toughness values of nuclear pressure vessel steel A508 class 3 are evaluated over a wide temperature range from lower to upper shelves. The strain distribution near the crack tip in the dynamic process of fracture is also obtained by applying a computer picture processing. (orig.)

  5. Influence of typical faults over the dynamic behavior of pantograph-catenary contact force in electric rail transport

    Rusu-Anghel, S.; Ene, A.

    2017-05-01

    The quality of electric energy capture and also the equipment operational safety depend essentially of the technical state of the contact line (CL). The present method for determining the technical state of CL based on advance programming is no longer efficient, due to the faults which can occur into the not programmed areas. Therefore, they cannot be remediated. It is expected another management method for the repairing and maintenance of CL based on its real state which must be very well known. In this paper a new method for determining the faults in CL is described. It is based on the analysis of the variation of pantograph-CL contact force in dynamical regime. Using mathematical modelling and also experimental tests, it was established that each type of fault is able to generate ‘signatures’ into the contact force diagram. The identification of these signatures can be accomplished by an informatics system which will provide the fault location, its type and also in the future, the probable evolution of the CL technical state. The measuring of the contact force is realized in optical manner using a railway inspection trolley which has appropriate equipment. The analysis of the desired parameters can be accomplished in real time by a data acquisition system, based on dedicated software.

    This study investigated the effects of ketamine on fluoxetine-induced antidepressant behavior using the forced swimming test (FST) in mice. In order to understand the possible role of N-methyl-d-aspartate (NMDA) neurotransmission in the antidepressant effect of fluoxetine, different groups of mice (n=10) were administered with acute ketamine (3mg/kg, i.p.), acute NMDA (75mg/kg and 150mg/kg, i.p.) and a 21-day chronic ketamine (15mg/kg, i.p./day) were administered prior to the administration of fluoxetine (20mg/kg, i.p.) in the mice. Antidepressant related behavior (immobility score) was measured using the forced swimming test. The results showed that the acute ketamine and fluoxetine alone treatments elicited a significant (pfluoxetine-induced decrease in immobility score. In contrast, pre-treatment with NMDA (150mg/kg) significantly (pfluoxetine-induced decrease in immobility score. On the other hand, chronic administration of ketamine significantly elicited an increase in immobility score as well as reversed the reduction induced by fluoxetine. Similarly, NMDA administration at both 75mg/kg and 150mg/kg increased immobility score in chronically administered ketamine groups. Furthermore, chronic administration of ketamine, followed by NMDA (75mg/kg) and fluoxetine significantly elevated the immobility score when compared with the group that received NMDA and fluoxetine but not chronically treated with ketamine. It can be suggested) that facilitation of NMDA transmission blocked fluoxetine-induced reduction in immobility score, while down-regulation of NMDA transmission is associated with increase in fluoxetine-induced antidepressant-related behavior in mice. Down-regulation of the NMDA transmission is proposed as an essential component of mechanism of suppression of depression related behaviors by fluoxetine. Modulation of NMDA transmission is suggested to be relevant in the mechanism of action of fluoxetine. Copyright © 2014 Elsevier Ireland Ltd. All rights

    Temporary workers make up a sizeable part of the labor force in many countries and typically receive wages that are significantly lower than their permanent counterparts. This paper uses an efficiency wage model to explain the wage gap between temporary and permanent workers. High......-performing temporary workers may gain promotion to permanent status, and a high wage to permanent workers therefore serves a dual purpose: it affects the effort of both permanent and temporary workers. Applying the model to the Korean experience, we discuss the effects of the labor market reforms in 1998 on inequality....

    2015-05-15

    Many different types of elastomeric rings have been developed to suit various needs in industry. The X-ring was introduced as a result of the limitations of O-rings that twist, especially during dynamic application. A better understanding of the behavior and the stress distribution of the X-ring under a uniform squeeze rate and internal pressure is needed. We analyzed the contact stresses and internal stresses developed in an X-ring before and after forcing-out by using the photoelastic experimental hybrid method, ascertained the packing ability of an X-ring, and studied the failure criterion of an X-ring under uniform squeeze rate and internal pressure. Forcing-out in the X-ring occurred when the internal pressure was 3.92 MPa. After forcing-out, at an internal pressure of 5.88 MPa, the two lobes on the upper contact surface merged one contact side of the upper side immensely. Even after extrusion of the X-ring, the X-ring can be used to effectively contain the fluid. This is because the effects of extrusion on the X-ring affected the stress distribution of only two lobes close to the assembly gap and the two lobes are merge into one lobe. In addition, our experimental results show that the maximum shear failure criterion is suitable for the prediction of failure in X-ring seals.

  11. Analysis of the mechanical behavior of single wall carbon nanotubes by a modified molecular structural mechanics model incorporating an advanced chemical force field

    Science.gov (United States)

    Eberhardt, Oliver; Wallmersperger, Thomas

    2018-03-01

    The outstanding properties of carbon nanotubes (CNTs) keep attracting the attention of researchers from different fields. CNTs are promising candidates for applications e.g. in lightweight construction but also in electronics, medicine and many more. The basis for the realization of the manifold applications is a detailed knowledge of the material properties of the carbon nanotubes. In particular for applications in lightweight constructions or in composites, the knowledge of the mechanical behavior of the CNTs is of vital interest. Hence, a lot of effort is put into the experimental and theoretical determination of the mechanical material properties of CNTs. Due to their small size, special techniques have to be applied. In this research, a modified molecular structural mechanics model for the numerical determination of the mechanical behavior of carbon nanotubes is presented. It uses an advanced approach for the geometrical representation of the CNT structure while the covalent bonds in the CNTs are represented by beam elements. Furthermore, the model is specifically designed to overcome major drawbacks in existing molecular structural mechanics models. This includes energetic consistency with the underlying chemical force field. The model is developed further to enable the application of a more advanced chemical force field representation. The developed model is able to predict, inter alia, the lateral and radial stiffness properties of the CNTs. The results for the lateral stiffness are given and discussed in order to emphasize the progress made with the presented approach.

    Full Text Available Objectives. Worldwide, over 200 million children are involved in child labor, with another 20 million children subjected to forced labor, leading to acute and chronic exposures resulting in safety and health (S&H risks, plus removal from formal education and play. This review summarized S&H issues in child labor, including forced or indentured domestic labor as other sectors of child labor. Specifically, we focused on exposures leading to S&H risks. Methods. We used PubMed, Scopus, Science Direct, and Google Scholar. References were in English, published in 1990–2015, and included data focused on exposures and S&H concerns of child labor. Results. Seventy-six journal articles were identified, 67 met criteria, 57 focused on individual countries, and 10 focused on data from multiple countries (comparing 3–83 countries. Major themes of concern were physical exposures including ergonomic hazards, chemical exposure hazards, and missed education. Childhood labor, especially forced, exploitative labor, created a significant burden on child development, welfare, and S&H. Conclusions. More field researche data emphasizing longitudinal quantitative effects of exposures and S&H risks are needed. Findings warranted developing policies and educational interventions with proper monitoring and evaluation data collection, plus multiple governmental, international organization and global economic reform efforts, particularly in lower-income, less developed countries.

    This study examines the effect of acoustic excitation using forced coaxial air on the flame characteristics of turbulent hydrogen non-premixed flames. A resonance frequency was selected to acoustically excite the coaxial air jet due to its ability to effectively amplify the acoustic amplitude and reduce flame length and NO{sub x} emissions. Acoustic excitation causes the flame length to decrease by 15% and consequently, a 25% reduction in EINO{sub x} is achieved, compared to coaxial air flames without acoustic excitation at the same coaxial air to fuel velocity ratio. Moreover, acoustic excitation induces periodical fluctuation of the coaxial air velocity, thus resulting in slight fluctuation of the fuel velocity. From phase-lock PIV and OH PLIF measurement, the local flow properties at the flame surface were investigated under acoustic forcing. During flame-vortex interaction in the near field region, the entrainment velocity and the flame surface area increased locally near the vortex. This increase in flame surface area and entrainment velocity is believed to be a crucial factor in reducing flame length and NO{sub x} emission in coaxial jet flames with acoustic excitation. Local flame extinction occurred frequently when subjected to an excessive strain rate, indicating that intense mass transfer of fuel and air occurs radially inward at the flame surface. (author)

    Using data on Members of the European Parliament (MEPs), we examine the impact of salaries on the composition and the behavior of legislators. Employing a differences-in-differences approach, we exploit the introduction of a law that equalized MEPs’ salaries which had previously differed by as much...... as a factor of ten. Increasing salaries raises the fraction of MEPs who run for reelection but decreases the quality of elected MEPs (proxied by college quality.)

    Depression is a serious psychological disorder that causes extreme economic loss and social problems. However, the conventional medications typically cause side effects that result in patients opting to out of therapy. Lemon balm (Melissa officinalis L., MO) is an old and particularly reliable medicinal herb for relieving feelings of melancholy, depression and anxiety. The present study aims to investigate the antidepressant-like activity of water extract of MO (WMO) by evaluating its influence on the behaviors and the relevant neurotransmitters of rats performed to forced swimming test. Two phases of the experiment were conducted. In the acute model, rats were administered ultrapure water (control), fluoxetine, WMO, or the indicated active compound (rosmarinic acid, RA) three times in one day. In the sub-acute model, rats were respectively administered ultrapure water (control), fluoxetine, or three dosages of WMO once a day for 10 days. Locomotor activity and depression-like behavior were examined using the open field test and the forced swimming test, respectively. The levels of relevant neurotransmitters and their metabolites in the frontal cortex, amygdala, hippocampus, and striatum were analyzed by high performance liquid chromatography. In the acute model, WMO and RA significantly reduced depressive-like behavior but the type of related neurotransmitter could not be determined. The results indicated that the effect of WMO administration on the reduction of immobility time was associated with an increase in swimming time of the rats, indicative of serotonergic neurotransmission modulation. Chromatography data validated that the activity of WMO was associated with a reduction in the serotonin turnover rate. The present study shows the serotonergic antidepressant-like activity of WMO. Hence, WMO may offer a serotonergic antidepressant activity to prevent depression and to assist in conventional therapies. Copyright © 2015. Published by Elsevier Ireland Ltd.

    According to FAO statistics, Iran is the largest exporter of pistachios. Kerman province -south east of Iran- has approximately 200000 hectares of pistachio orchards, which provides practically 80% of whole country production of pistachios. After harvesting the pistachio, nuts must be washed to prevent staining. Therefore the nuts have almost 40% moisture content and it must be decreased to storage moisture of 6% or below. Simply decreasing in the moisture content of the products is called drying. In some areas where the environment conditions meet the minimum standard, solar drying can be an alternative approach for drying agricultural products. This work deals with the design, construction and testing a mixed-mode forced convection PV operated solar dryer. (orig.)

    Full Text Available The empowerment of Persons with Disabilities (PWD has recently attracted the attention of the Indonesian government. Several initiatives have been made to empower their life, especially the establishment of Act No. 8/2016 which enhances their right to inclusive economic activities. This study aims to map PWD in Indonesian labor market. Specifically, it analyzes the characteristics of employed and unemployed PWD. It explored Labor Force Survey (Sakernas, which began to concern on disability issue in 2016. The results show that PWD prevalence varies highly among provinces led by West Sumatera, East Nusa Tenggara, and South Sulawesi and that PWD has lower labor participation rate than that of PWOD. It may indicate the significant presence of discouraged workers among PWD.

    The female military population represents a high-risk group for preterm labor and other adverse pregnancy outcomes. As the number of women entering the armed forces continues to increase, concerns regarding the effects of military service on pregnancy must persist. Although active duty females have access to prenatal care and maintain consistent follow-up, previous research has noted a 5-fold increase in preterm labor compared with civilian working women. Hospitalization and loss of work attributable to pregnancy complications directly affect productivity and mission accomplishment; therefore, it is crucial to identify those at risk to institute measures that will prevent such occurrences and decrease time away from work. This article provides a review of the existing literature concerning preterm labor in military women, comparisons with the civilian population, and recommendations for future research.

    Our previous research indicates that the extracellular signal-regulated kinase (ERK)-cyclic AMP-responsive-element-binding protein (CREB) signal system may be involved in the molecular mechanism of depression. The present study further investigated the effect of antidepressant fluoxetine on the ERK-CREB signal system and the depressive-like behaviors in rats. Fluoxetine was administrated to either naive rats or stressed rats for 21 days. The results showed that chronic forced swim stress induced depressive-like behaviors and decreased the levels of P-ERK2, P-CREB, ERK1/2 and CREB in hippocampus and prefrontal cortex. Fluoxetine alleviated the depressive-like behaviors and reversed the disruptions of the P-ERK2 and P-CREB in stressed rats. Fluoxetine also exerted mood-elevating effect and increased the levels of the P-ERK2 and P-CREB in naive rats. These results suggest that the ERK-CREB signal system may be the targets of the antidepressant action of fluoxetine and participate in the neuronal mechanism of depression.

    The lack of appropriate animal models for bipolar disorder (BPD) is a major factor hindering the research of its pathophysiology and the development of new drug treatments. In line with the notion that BPD might represent a heterogeneous group of disorders, it was suggested that models for specific domains of BPD should be developed. The present study tested the possible utilization of the forced swim test (FST) as a model for the heightened vigor and goal-directed behavior domain of mania, using mice with low baseline immobility. Black Swiss mice were previously identified to have low immobility in the FST but similar spontaneous activity levels compared with several other mice strains. Thus, spontaneous activity and behavior in the FST were evaluated following treatment with the mood stabilizer valproate and the antidepressant imipramine. The results indicated that valproate increased immobility in the FST without affecting spontaneous activity whereas imipramine had no effect in the FST but increased spontaneous activity. These findings suggest that in mice with low baseline immobility scores, the FST might be a useful model for the elevated vigor and goal-directed behavior domain of mania. As such, this test might be well integrated into a battery of models for different domains of BPD.

    In Hungary large numbers of women began to perform paid work outside the household from the 1960s on. Among women 15-54 years old the proportion engaged in income-producing activity in the 1930s was 30.8%, almost 50% in 1960, over 70% in 1980 (vs. 87.4% for men). In Hungary women in the early reproductive years have a low employment level, but once their children are kindergarten age their employment level approximates that of men. In 1990 there were 360,000 children 0-5 years old who did not attend child care centers or kindergartens, presumably they were taken care of at home. The increasing trend of female employment is one of the most direct causes of the decline of fertility. The number of children also affects the employment of women. In the United Kingdom twice as many women under the age of 34 with 1 or 2 children work than in France; 37% of mothers with children 0-4 years old and 53% with children 5-9 years old are employed. In Sweden 90% of mothers 35-44 years old with children 0-6 years old and 95% of them with children 7-16 years old are employed. In the United States 48.7% of mothers with children under the age of 6 are employed vs. 62.1% of mothers with children 6-17 years old. Maternity leave of several weeks or months is common in Europe. In a number of industrialized countries and also in Hungary the working and lactating mother gets favorable working hours, increased vacation, and sick leave for caring for sick children. In Hungary child care centers for children under 3 are operating in only 1300 settlements out of 3300 settlements. Similarly, in most western European countries only 2-6% of these children could be accommodated during 1986-89 except for Denmark (48%), Belgium (20%), and France (20%). The situation was much better for children over 3, where the average was 60%. In 1988 part-time work among women with children 0-6 years years old ranged from 10.3 to 57.7% in 11 European countries, but the loss of income and career opportunities are being addressed internationally to make this option truly attractive.

  13. CHILD LABOR ABUSE: LEGAL ASPECTS

    2016-01-01

    Full Text Available The paper addresses the problem of child labor and ways of protection from child labor abuse. Child labor is a negative social phenomenon that is widespread throughout the world, and also in Republic of Macedonia. International and national institutions and organizations are making serious efforts to eradicate this negative phenomenon, through the adoption of numerous international legal instruments (conventions, recommendations, declarations, etc.. Child labor as a phenomenon refers to the employment of children in any work that deprives children of their childhood, interferes with their ability of education, and that is socially, mentally, physically, or morally dangerous and harmful. All international organizations define this practice as exploitative and destructive to the development of the whole society. With international legal instruments of the UN, ILO, Council of Europe and the EU child labor is strictly prohibited. There are some important differences which exist between the many kinds of work that is done by children. Some of them are demanding and difficult, others are hazardous and morally reprehensible. Children are doing a very wide range of activities and tasks when they work.

    Major purpose of the Slab Core Test Program is to investigate the two-dimensional thermal-hydraulic behavior in the core during the reflood phase of a PWR-LOCA. It was revealed in the previous Slab Core Test Facility (SCTF) Core-II test results that the heat transfer was enhanced in the higher power bundles and degraded in the lower power bundles in the non-uniform radial power profile tests. In order to separately evaluate the effect of the radial power (Q) distribution itself and the effect of the radial temperature (T) distribution, four tests were performed with steep Q and T, flat Q and T, steep Q and flat T, and flat Q and steep T. Based on the test results, it was concluded that the radial temperature distribution which accompanied the radial power distribution was the dominant factor of the two-dimensional thermal-hydraulic behavior in the core during the initial period. Selected data from these four tests are also presented in this report. Some data from Test S2-12 (steep Q, T) were compared with TRAC post-test calculations performed by the Los Alamos National Laboratory. (author)

    Tetra-n-butyl-ammonium bromide (TBAB) clathrate hydrate slurry (CHS) is one kind of secondary refrigerants, which is promising to be applied into air-conditioning or latent-heat transportation systems as a thermal storage or cold carrying medium for energy saving. It is a solid-liquid two phase mixture which is easy to produce and has high latent heat and good fluidity. In this paper, the heat transfer characteristics of TBAB slurry were investigated in a horizontal stainless steel tube under different solid mass fractions and flow velocities with constant heat flux. One velocity region of weakened heat transfer was found. Moreover, TBAB CHS was treated as a kind of Bingham fluids, and the influences of the solid particles, flow velocity and types of flow on the forced convective heat transfer coefficients of TBAB CHS were investigated. At last, criterial correlations of Nusselt number for laminar and turbulent flows in the form of power function were summarized, and the error with experimental results was within {+-}20%. (author)

    Full Text Available Lindera obtusiloba extracts are commonly used as an alternative medicine due to its numerous health benefits in Korea. However, the antidepressant-like effects of L. obtusiloba extracts have not been fully elucidated. In this study, we aimed to determine whether L. obtusiloba extracts exhibited antidepressant-like activity in rats subjected to forced swim test (FST-induced depression. Acute treatment of rats with L. obtusiloba extracts (200 mg/kg, p.o. significantly reduced immobility time and increased swimming time without any significant change in climbing. Rats treated with L. obtusiloba extracts also exhibited a decrease in the limbic hypothalamic-pituitary-adrenal (HPA axis response to the FST, as indicated by attenuation of the corticosterone response and decreased c-Fos immunoreactivity in the hippocampus CA3 region. In addition, L. obtusiloba extracts, at concentrations that were not affected by cell viability, significantly decreased luciferase activity in response to cortisol in a concentration-dependent manner by the glucocorticoid binding assay in HeLa cells. Our findings suggested that the antidepressant-like effects of L. obtusiloba extracts were likely mediated via the glucocorticoid receptor (GR. Further studies are needed to evaluate the potential of L. obtusiloba extracts as an alternative therapeutic approach for the treatment of depression.

    Full Text Available BACKGROUND Germany, like many OECD countries, faces a shift in the age composition of its population,and will face an even more drastic demographic change in the years ahead. From a theoretical point of view, decreasing cohort sizes may on the one hand reduce unemployment due to inverse cohort crowding or, on the other hand, increase unemploymentif companies reduce jobs disproportionately. Consequently, the actual effect of cohort shrinkage on employment and unemployment is an empirical question. OBJECTIVE We quantitatively assess the relationship between (unemployment and cohort sizes. METHODS We analyze a long panel of population and labor-market data for Western German labor market regions. We isolate the direct, statistical effect of aging in a decomposition approach and estimate the overall effect by regression. In this context, we account for the likely endogeneity of cohort size due to migration of the young workforce across regions using lagged births as instrument. RESULTS The direct effect of the age composition of the labor force on unemployment is negligible.In contrast, the elasticities of unemployment and employment with regard to the labor-market entry cohort's size are significantly positive or negative, respectively. The causal effect indicates an over-elastic reaction by unemployment. CONCLUSIONS Our results provide good news for the Western German labor market: small entry cohorts are indeed likely to decrease the overall unemployment rate and thus to improve the situation of job seekers. Accordingly, we find the employment rate is positively affected by a decrease in the youth proportion.

    2017-06-01

    Full Text Available Emerging research brings more attention to labor trafficking in the United States. However, very few efforts have been made to better understand or respond to labor trafficking of minors. Cases of children forced to work as domestic servants, in factories, restaurants, peddling candy or other goods, or on farms may not automatically elicit suspicion from an outside observer as compared to a child providing sexual services for money. In contrast to sex trafficking, labor trafficking is often tied to formal economies and industries, which often makes it more difficult to distinguish from "legitimate" work, including among adolescents. This article seeks to provide examples of documented cases of child labor trafficking in the United States, and to provide an overview of systemic gaps in law, policy, data collection, research, and practice. These areas are currently overwhelmingly focused on sex trafficking, which undermines the policy intentions of the Trafficking Victims Protection Act (2000, the seminal statute criminalizing sex and labor trafficking in the United States, its subsequent reauthorizations, and international laws and protocols addressing human trafficking.

  1. Emotional labor in nursing praxis

    Directory of Open Access Journals (Sweden)

    José Manuel da Silva Vilelas

    Full Text Available Healthcare work is, by nature, an activity full of intense emotions and therefore, is opportune ground for exploring emotions in the workplace in different contexts of nursing care. It is a very fertile terrain if care is focused on the emotions of the client, nurses, healthcare teams, and on the interaction of all actors involved. This article presents a theoretical reflection exploring the concept of emotional labor in the context of nursing care. Theoretical references from several fields of knowledge, namely sociology and nursing, have been adopted to conceptualize the theme. Studies on emotional labor have contributed toward the understanding of the key issue of emotional management in healthcare institutions and both its positive and negative impact on clients and professionals. The development of the theme of emotional labor in nursing has given rise to numerous theoretical approaches and perspectives explaining this concept.

  3. NMDA-NO signaling in the dorsal and ventral hippocampus time-dependently modulates the behavioral responses to forced swimming stress.

    Hodological and genetic differences between dorsal (DH) and ventral (VH) hippocampus may convey distinct behavioral roles. DH is responsible for mediating cognitive process, such as learning and memory, while VH modulates neuroendocrine and emotional-motivational responses to stress. Manipulating glutamatergic NMDA receptors and nitric oxide (NO) systems of the hippocampus induces important changes in behavioral responses to stress. Nevertheless, there is no study concerning functional differences between DH and VH in the modulation of behavioral responses induced by stress models predictive of antidepressant effects. Thus, this study showed that reversible blockade of the DH or VH of animals submitted to the forced swimming test (FST), by using cobalt chloride (calcium-dependent synaptic neurotransmission blocker), was not able to change immobility time. Afterwards, the NMDA-NO system was evaluated in the FST by means of intra-DH or intra-VH administration of NMDA receptor antagonist (AP7), NOS1 and sGC inhibitors (N-PLA and ODQ, respectively). Bilateral intra-DH injections after pretest or before test were able to induce antidepressant-like effects in the FST. On the other hand, bilateral VH administration of AP-7, N-PLA and ODQ induced antidepressant-like effects only when injected before the test. Administration of NO scavenger (C-PTIO) intra-DH, after pretest and before test, or intra-VH before test induced similar results. Increased NOS1 levels was associated to stress exposure in the DH. These results suggest that the glutamatergic-NO system of the DH and VH are both able to modulate behavioral responses in the FST, albeit with differential participation along time after stress exposure.

  4. Social Justice Attitudes and Concerns for Labor Standards

    Directory of Open Access Journals (Sweden)

    Michaela Schulz

    2017-01-01

    Full Text Available This study utilizes an adapted version of the Social Justice Scale to capture and assess the extent to which social-justice-related values and attitudes toward labor standards relate to consumer intentions and behaviors. This social cognitive model assesses, based on Ajzen’s theory of planned behavior, how “perceived behavior control” affects these behaviors either directly or indirectly through consumers’ intentions. It is hypothesized that individuals who value fairness and equity in social interactions are going to be more likely to engage with businesses that are known for ethical business practices and abstain from firms that are known to violate labor rights. The results confirm that consumers who are concerned with social justice are less likely to conduct business with enterprises that have the reputation of violating both human rights and labor rights. However, the results also reveal that consumers with low levels of “perceived behavioral control” justify their consumer behaviors as they do not think that they can make a difference.

    Hypnotherapy is an integrative mind-body technique with therapeutic potential in various health care applications, including labor and birth. Evaluating the efficacy of this modality in controlled studies can be difficult, because of methodologic challenges, such as obtaining adequate sample sizes and standardizing experimental conditions. Women using hypnosis techniques for childbirth in hospital settings may face barriers related to caregiver resistance or institutional policies. The potential anxiolytic and analgesic effects of clinical hypnosis for childbirth merit further study. Nurses caring for women during labor and birth can increase their knowledge and skills with strategies for supporting hypnotherapeutic techniques. © 2014 AWHONN.

    Highlights: ► Localized corrosion of a new N-based tool alloy (Fe–Cr–V–N) has been studied. ► One-pass mode of scanning Kelvin force microscopy (KFM) was used in the study. ► The focus was on correlation between microstructure and localized corrosion. - Abstract: Microstructure influence on corrosion behavior of an N-based tool alloy (Fe–Cr–V–N) has been studied. Electron microscopy analysis showed two types of hard phases in the alloy. One-pass mode scanning Kelvin force microscopy (KFM) was used to investigate relative nobility of the hard phases. Volta potential mapping indicates higher nobility for the hard phases than the alloy matrix, and, the V- and N-rich particles exhibit the highest Volta potential. Post-polarization analysis by SEM revealed localized dissolution initiated in matrix regions adjacent to hard phase particles, and the boundary region surrounding the Cr- and Mo-rich particles is more prone to localized corrosion.

    High rates of West Nile virus (WNV) transmission to humans are associated with exceptionally hot and dry summers. This is paradoxical since the eggs of Culex vectors of WNV depend on the persistence of containers with water, which decline during droughts. We examined the effects of forced-egg retention on the reproductive success of female Culex pipiens as well as behavioral responses, such as likelihood of secondary blood meals. As controls we examined the effects of female age and delayed mating. We found that early mating is essential to achieve reproductive success and, consistent with an "all-or-none" ovipositing strategy, C. pipiens females are able to retain considerable reproductive potential while searching for oviposition sites. Specifically, although forced-egg retention resulted in significant decreases in fitness, the decline was moderate for 5 weeks and most can be accounted for by increases in female age. Consequently, no females took blood more than once per gonotrophic cycle, which eliminates the possibility that heightened vectorial capacity due to multiple blood-feedings increases WNV transmission during periods of drought. Instead, our findings suggest that during droughts populations of C. pipiens have time to locate the remaining water holes, which are associated with human populations and WNV-competent bird species.

    Full Text Available The aim of the study is to compare behavioral and EEG reactions of primary school-aged children during the recognition of syntactic errors in emotionally (positively or negatively colored sentences that appeal to the choice of the child differently. 20 children (mean age 9,0±0,3 years, 12 boys, 8 girls were examined. We found out that the children with a high quality of solving a linguistic task concentrate all their attention on finding an error in the sentences, and children with a low quality of solving a task demonstrate increased emotionality, possibly connected with their unsuccessfulness. The strongest EEG reactions in the ranges of alpha- and theta- rhythms were recorded in children with slow speed and bad quality of the solution of the task. The recognition of sentences with negative emotions took longer than sentences with positive emotions. The increase of emotions (synchronization in theta range during the recognition of negative sentences was provoked by the expectation of failure and “identification” with it. The children found the mistake better in the sentences with their own choice than in the sentences that describes the forced-choice situation. Desynchronization (i.e. decrease in the spectral power and synchronization (i.e. increase in spectral power was detected on the EEG in the alpha-rhythm range. Desynchronization was associated with the recognition of sentences describing the children’s own choice; synchronization was recorded when recognizing sentences describing the forced-choice situation.

    The mechanical behavior and microstructure characteristics of Ti-5Mo-5V-8Cr-3Al alloy were investigated with hat-shaped samples compressed under quasi-static and dynamic loading. Compared with the quasi-static loading, a higher shear stress peak and a shear instability stage were observed during the dynamic shear response. The results showed that an adiabatic shear band consisting of ultrafine equiaxed grains was only developed in the dynamic specimen, while a wider shear region was formed in the quasi-static specimen. The microhardness measurements revealed that shear region in the quasi-static specimen and adiabatic shear band in the dynamic specimen exhibited higher hardness than that of adjacent regions due to the strain hardening and grain refining, respectively. A stable orientation, in which the crystallographic {110} planes and <111> directions were respectively parallel to the shear plane and shear direction, developed in both specimens. And the microtexture of the adiabatic shear band was more well-defined than that of the shear region in the quasi-static specimen. Rotational dynamic recrystallization mechanism was suggested to explain the formation of ultrafine equiaxed grains within the adiabatic shear band by thermodynamic and kinetic calculations.

    In this study, the antidepressant-like effects of Morus alba fractions in rats were investigated in the forced swim test (FST). Male Wistar rats (9-week-old) were administered orally the M. alba ethyl acetate (EtOAc 30 and 100 mg/kg) and M. alba n-butanol fractions (n-BuOH 30 and 100 mg/kg) every day for 7 consecutive days. On day 7, 1 h after the final administration of the fractions, the rats were exposed to the FST. M. alba EtOAc fraction at the dose of 100 mg/kg induced a decrease in immobility behavior (p alba EtOAc fraction at the dose of 100 mg/kg decreased the hypothalamic-pituitary-adrenal (HPA) axis response to the stress, as indicated by an attenuated corticosterone response and decreased c-fos immunoreactivity in the hippocampal and hypothalamic paraventricular nucleus (PVN) region. These findings demonstrated that M. alba EtOAc fraction have beneficial effects on depressive behaviors and restore both altered c-fos expression and HPA activity.

  20. A global strategy for labor.

    Science.gov (United States)

    Faux, Jeff

    2002-01-01

    The rules of the global market were established to protect the interests of investors at the expense of workers and they shift benefits to investors, costs to workers. Globalization is measured by the interests of investors. But 20 years of investor protectionism show that growth has slowed and equality has gotten worse. The purpose of neo-liberal policies has been to discipline labor to free capital from having to bargain with workers over gains from rising productivity. But such bargaining is the essence of a democratic market. Uncontrolled globalization puts government's domestic policies on the side of capital. In an economy whose growth depends on foreign markets, rising domestic wages make it harder to compete internationally. There has been a general deterioration of labor's position relative to capital's. A global marketplace implies a global politics, and the real work happens when representatives of multi-national business privately negotiate the rules. Labor must change the framework in which the investor class pursues its interest across borders, while workers are constricted by borders. Labor unions are critical; they can deny the human resource necessary for profits. The strike is the ultimate threat to investors. One solution: a "grand bargain" linking development with broadly increased living standards connected to planning for sustainable development to create a global social contract. Workers have advantages: they are the majority and they are indispensable.

  1. Misguided guidelines for managing labor.

    Science.gov (United States)

    Cohen, Wayne R; Friedman, Emanuel A

    2015-06-01

    In a recent review we expressed concerns about new guidelines for the assessment and management of labor recommended jointly by the American Congress of Obstetricians and Gynecologists (ACOG) and the Society for Maternal-Fetal Medicine (SMFM). These guidelines are based heavily on a new concept of how cervical dilatation and fetal descent progress, derived from the work of Zhang et al. In their Viewpoint article they have addressed, but not allayed, the concerns we described in our review. We assert that the dilatation curve promulgated by Zhang et al cannot be reconciled with direct clinical observation. Even if they were correct, however, it still does not follow that the ACOG/SMFM guidelines should recommend replacing the coherent system of identifying and managing labor aberrations described by Friedman. That system is grounded in well-established clinical principles based on decades of use and the objectively documented association of some labor abnormalities with poor fetal and maternal outcomes. Recommendations for new clinical management protocols should require the demonstration of superior outcomes through extensive, preferably prospective, assessment. Using untested guidelines for the management of labor may adversely affect women and children. Even if those guidelines were to reduce the currently excessive cesarean delivery rate, the price of that benefit is likely to be a trade-off in harm to parturients and their offspring. The nature and degree of that harm needs to be documented before considering adoption of the guidelines. Copyright © 2015 Elsevier Inc. All rights reserved.

    Several clinical reports have postulated a beneficial effect of the addition of a low dose of risperidone to the ongoing treatment with antidepressants in treatment-resistant depression. The present study aimed to examine the effect of treatment with fluoxetine or mirtazapine, given separately or jointly with risperidone, on active behavior and plasma corticosterone level in male Wistar rats subjected to the forced swim test (FST). The obtained results showed that fluoxetine (5 mg/kg), mirtazapine (5 and 10 mg/kg) or risperidone (0.05 and 0.1 mg/kg) did not change the active behavior of rats in the FST. However, co-treatment with fluoxetine (10 mg/kg) and risperidone (0.1 mg/kg) induced an antidepressant-like effect in that test because it significantly increased the swimming time and decreased the immobility time, while combined treatment with mirtazapine at 5 and 10 mg/kg and risperidone at 0.05 and 0.1 mg/kg evoked a significant increase in the swimming time and also climbing, and decreased the immobility time. WAY 100635 (a 5-HT(1A) receptor antagonist) at a dose of 0.1 mg/kg inhibited the antidepressant-like effect induced by co-administration of fluoxetine or mirtazapine and risperidone. Active behavior in that test did not reflect an increase in general activity, since combined treatment with fluoxetine or mirtazapine and risperidone failed to enhance the exploratory activity of rats. Co-treatment with fluoxetine or mirtazapine and risperidone did not reduce the stress-induced increase in plasma corticosterone concentration in animals subjected to the FST. The obtained results indicate that risperidone applied in a low dose enhances the antidepressant-like activity of fluoxetine and mirtazapine in the FST (but does not normalize the stress-induced increase in corticosterone level in these rats), and that 5-HT(1A) receptors may play some role in these effects.

  5. Competition for labor resources: losses of the Amur region

    2017-01-01

    Full Text Available The purpose of the article is to define labor losses of the Amur region because of the competition of regions. Each region, directly or indirectly, seeks to attract and keep in its territory highly skilled labor force. Shortage of labor force slows down development of the economy of the region. Thus, because of the depopulation, the demand for the produced and consumed goods and services in the region is decreasing. The decrease in demand influences tax reduction and non-tax revenues in budgets of various levels, reduction of employment of labor resources, increase in unemployment, increase in cost of products and rendered services, reduction of the gross regional product, growth of social tension in the society.Under conditions of the competition between regions for labor resources, other things being equal, the outflow of labor resources occurs from regions with a rather low level of compensation to regions with a rather high level of the salary. At the same time, the population leaves, as a rule, the provincial and less developed regions and concentrates in the largest metropolitan areas. In the competition for labor resources some regions win and get essential advantages in social and economic development, others sustain considerable losses. Statistical methods of analyzing social and economic phenomena and processes were used as tools for carrying out the research: indexes of dynamics, structure, and tabular and graphic methods of visualization of quantitative data.As a result of the conducted statistical research, it was found out that the population of the Amur region decreases annually, at the same time the decline in the population of the region is long-term and steady in nature. Over 25 years the Amur region lost population amounting to the population of the whole city. The present work shows that the tendency of demographic aging of the population characteristic of many regions of the country is observed in the Amur region. Decrease

    Contemporary labor and birth population norms should be the basis for evaluating labor progression and determining slow progress that may benefit from intervention. The aim of this article is to present guidelines for a common, evidence-based approach for determination of active labor onset and diagnosis of labor dystocia based on a synthesis of existing professional guidelines and relevant contemporary publications. A 3-point approach for diagnosing active labor onset and classifying labor dystocia-related labor aberrations into well-defined, mutually exclusive categories that can be used clinically and validated by researchers is proposed. The approach comprises identification of 1) an objective point that strictly defines active labor onset (point of active labor determination); 2) an objective point that identifies when labor progress becomes atypical, beyond which interventions aimed at correcting labor dystocia may be justified (point of protraction diagnosis); and 3) an objective point that identifies when interventions aimed at correcting labor dystocia, if used, can first be determined to be unsuccessful, beyond which assisted vaginal or cesarean birth may be justified (earliest point of arrest diagnosis). Widespread adoption of a common approach for diagnosing labor dystocia will facilitate consistent evaluation of labor progress, improve communications between clinicians and laboring women, indicate when intervention aimed at speeding labor progress or facilitating birth may be appropriate, and allow for more efficient translation of safe and effective management strategies into clinical practice. Correct application of the diagnosis of labor dystocia may lead to a decrease in the rate of cesarean birth, decreased health care costs, and improved health of childbearing women and neonates. © 2015 by the American College of Nurse-Midwives.

In the one acting of the referred activities intervenes individuals that, in reason of their work, they have contact with this energy type, which is potentially dangerous for the health in reason of the radioactivity flight. Although those workers are 'aided' for a series of relative standards to the observance of safety, hygiene and protection measures in the event of work risks, the technicity that is required to determine the potential risk that it is generated with the handling of radioactive products it makes that single specialized in the matter authorities can evaluate and, therefore, to watch over the safety conditions in those that work is developed.

    The aim of the current systematic review is to examine the relationship between trauma and HIV risk behaviors among both forced and unforced migrant populations from low and middle income countries (LMIC). We conducted a review of studies published from 1995 to 2014. Data were extracted related to (1) the relationship between trauma and HIV risk behaviors, (2) methodological approach, (3) assessment methods, and (4) differences noted between forced and unforced migrants. A total of 340 records were retrieved with 24 studies meeting inclusion criteria. Our review demonstrated an overall relationship between trauma and HIV risk behaviors among migrant populations in LMIC, specifically with sexual violence and sexual risk behavior. However, findings from 10 studies were not in full support of the relationship. Findings from the review suggest that additional research using more rigorous methods is critically needed to understand the nature of the relationship experienced by this key-affected population.

    2015-01-01

    This article borrows from the intersectionality literature to investigate how legal status, labor market position, and family characteristics structure the labor supply of immigrant Latinas in Durham, NC, a new immigrant destination. The analysis takes a broad view of labor force participation, analyzing the predictors of whether or not women work; whether and how the barriers to work vary across occupations; and variation in hours and weeks worked among the employed. I also explicitly investigate the extent to which family constraints interact with other social characteristics, especially legal status, in shaping women’s labor market position. Results highlight that immigrant Latinas experience multiple, interrelated constraints on employment owing to their position as low-skill workers in a labor market highly segregated by gender and nativity, to their status as members of a largely undocumented population, and as wives and mothers in an environment characterized by significant work-family conflict.

    While translational evidence suggests that long-chain omega-3 fatty acid status is positively associated with the efficacy of selective serotonin reuptake inhibitor drugs, the neurochemical mechanisms mediating this interaction are not known. Here, we investigated the effects of dietary omega-3 (n-3) fatty acid insufficiency on the neurochemical and behavioral effects of chronic fluoxetine (FLX) treatment. Female rats were fed diets with (CON, n=56) or without (DEF, n=40) the n-3 fatty acids during peri-adolescent development (P21-P90), and one half of each group was administered FLX (10mg/kg/day) for 30days (P60-P90) prior to testing. In adulthood (P90), regional brain serotonin (5-HT) and 5-hydroxyindoleacetic (5-HIAA) concentrations, presynaptic markers of 5-HT neurotransmission, behavioral responses in the forced swim test (FST), and plasma FLX and norfluoxetine (NFLX) concentrations were investigated. Peri-adolescent n-3 insufficiency led to significant reductions in cortical docosahexaenoic acid (DHA, 22:6n-3) composition in DEF (-25%, p≤0.0001) and DEF+FLX (-28%, p≤0.0001) rats. Untreated DEF rats exhibited significantly lower regional 5-HIAA/5-HT ratios compared with untreated CON rats, but exhibited similar behavioral responses in the FST. In both CON and DEF rats, chronic FLX treatment similarly and significantly decreased 5-HIAA concentrations and the 5-HIAA/5-HT ratio in the hypothalamus, hippocampus, and nucleus accumbens, brainstem tryptophan hydroxylase-2 mRNA expression, and immobility in the FST. While the FLX-induced reduction in 5-HIAA concentrations in the prefrontal cortex was significantly blunted in DEF rats, the reduction in the 5-HIAA/5-HT ratio was similar to CON rats. Although plasma FLX and NFLX levels were not significantly different in DEF and CON rats, the NFLX/FLX ratio was significantly lower in DEF+FLX rats. These preclinical data demonstrate that n-3 fatty acid deficiency does not significantly reduce the effects of chronic

However, there remain gaps in the data required to understand the size and composition of the workforce needed to meet the demand for solar power. Through primary research on the U.S. solar installation employer base, this report seeks to address that gap, improving policymakers and other solar stakeholders understanding of both the evolving needs of these employers and the economic opportunity associated with solar market development. Included are labor market data covering current U.S. employment, expected industry growth, and employer skill preferences for solar installation-related occupations. This study offers an in-depth look at the solar installation sectors. A study published by the Solar Foundation in October 2011 provides a census of labor data across the entire solar value chain.

    Nanotechnology’s effects on labor and employment have received little attention within research and debates on the social implications of nanotechnology. This article shows that, in spite of its incipient development, nanotechnology is unquestionably moving toward manufacturing, involving a still very small but increasing component of the labor force. Based on secondary data and the literature review, I compose a picture of the emerging jobs in nanotechnology and highlight four emerging trends in nanotechnology workers’ skills requirements. I show that, in addition to job creation, nanotechnology diffusion is likely to pose labor market changes that may be disruptive for some categories of workers.

    The pharmacological treatment of major depression is mainly based on drugs elevating serotonergic (5-HT) activity. Specifically, selective 5-HT reuptake inhibitors, including Fluoxetine (FLX), are the most commonly used for treatment of major depression. However, the understanding of the mechanism of action of FLX beyond its effect of elevating 5-HT is limited. The interaction between serotoninergic system and neuropeptides signaling could be a key aspect. We examined the ability of the neuropeptide Galanin(1-15) [GAL(1-15)] to modulate the behavioral effects of FLX in the forced swimming test (FST) and studied feasible molecular mechanisms. The data show that GAL(1-15) enhances the antidepressant-like effects induced by FLX in the FST, and we demonstrate the involvement of GALR1/GALR2 heteroreceptor complex in the GAL(1-15)-mediated effect using in vivo rat models for siRNA GALR1 or GALR2 knockdown. Importantly, 5-HT1A receptors (5HT1A-R) also participate in the GAL(1-15)/FLX interactions since the 5HT1AR antagonist WAY100635 blocked the behavioral effects in the FST induced by the coadministration of GAL(1-15) and FLX. The mechanism underlying GAL(1-15)/FLX interactions affected the binding characteristics as well as the mRNA levels of 5-HT1A-R specifically in the dorsal hippocampus while leaving unaffected mRNA levels and affinity and binding sites of this receptor in the dorsal raphe. The results open up the possibility to use GAL(1-15) as for a combination therapy with FLX as a novel strategy for treatment of depression. Copyright © 2017 Elsevier Ltd. All rights reserved.

  20. Modulatory effect of cilostazol on tramadol-induced behavioral and neurochemical alterations in rats challenged across the forced swim despair test

    Full Text Available Pain-associated depression is encountered clinically in some cases such as cancer, chronic neuropathy, and after operations. Tramadol is an opioid analgesic drug that may modulate monoaminergic neurotransmission by inhibition of noradrenaline and serotonin reuptake that may contribute to its antidepressant-like effects. Clinically, tramadol is used either alone or in combination with other NSAIDs in the treatment of cases associated with pain and depression, e.g. low back pain, spinal cord injury, and post-operative pain management. However, tramadol monotherapy as an antidepressant is impeded by severe adverse effects including seizures and serotonin syndrome. Interestingly, phosphodiesterase-III inhibitors demonstrated novel promising antidepressant effects. Among which, cilostazol was reported to attenuate depression in post-stroke cases, geriatrics and patients undergoing carotid artery stenting. Therefore, this study was carried out to investigate the possible antidepressant-like effects of tramadol and/or cilostazol on the behavioral level in experimental animals, and to examine the neurochemical and biochemical effects of tramadol, cilostazol and their combination in rats, in order to explore the probable mechanisms of action underlying their effects. To achieve our target, male albino mice and rats were randomly allocated into five groups and administered either vehicle for control, fluoxetine (20 mg/kg, p.o., tramadol HCl (20 mg/kg, p.o., cilostazol (100 mg/kg, p.o., or combination of both tramadol and cilostazol. At day 14, mice and rats were challenged in the tail suspension test and forced swim test, respectively. Rats were sacrificed and brains were isolated for determination of brain monoamines, MDA, NO, SOD, and TNF-α. The current results showed that concurrent administration of cilostazol to tramadol-treated animals modulated depression on the behavioral level, and showed ameliorative neurochemical and biochemical effects
