The aim of this paper is to discuss labor force planning issues for allied health professionals in Australia. Health system reform and changes in the demand for health labor, combined with key characteristics of the professions, will have a profound influence on future needs for career development of allied health professionals. Key issues include the increasing need for allied health professionals to undertake business management and public health training, the growing trend of multiskilling versus specialization, and the need for the professions to diversify their skill base to ensure a range of career options in a changing health care system. The challenge for allied health professions is to improve tools of analysis in relation to labor force planning and to systematically investigate various factors influencing labor force supply and demand, on both a short-term and long-term basis.

Soviet fertility, labor-force participation, and marital stability.

1983-06-01

A simultaneous-equations model of Soviet fertility and labor-force participation is estimated from a cross section of 72 oblast's of the Russian Republic (RSFSR) reported in the 1970 census. The construction of the model is based on the neoclassical theory of household behavior. Simulated changes capture effects of policy changes in the exogenous variables on Soviet fertility and the female labor supply. The exogenous variables investigated are child care facilities (CC), urbanization ratio (URB), male education (MALED), and female education (FEMED). It was found that an increase in FEMED affects labor force participation (LFP) directly and indirectly through impact on birth rate (BR). Increase in CC raise both LFP and BR; increases in FEMED causes womens withdrawal from the labor force and one would expect this to raise BR; however, FEMED raises the opportunity costs of fertility sufficiently to neutralize this effect. Increasing urbanization does not affect participation in a significant way, but it does retard fertility. This effect works through LFP's impact on BR and the indirect effect working through marital stability. A final set of simulations captured the impact of upward shocks of LFP, BR, and the ratio of divorces to marriages (DIV/MAR) on the endogenous variables. Such changes could occur through changes in abortion laws, tightening of divorce laws, or changes in labor legislation. Participation is reduced by the fertility shock, just as fertility is retarded by the LPF and marital stability shocks. Evidence of a backward-bending labor-supply curve was also found. The model is illustrated by tables and charts.

Female labor force participation and female mortality in Wisconsin 1974-1978.

The following research question is addressed in the study: what effect will the entrance of women into the labor force have on female mortality rates for all causes of death combined as well as specific causes relating to occupational stress, behavioral factors and physical hazards associated with occupation? This question is examined through comparisons of age, marital status and occupation-specific death rates for all causes of death combined and for selected causes of death. Death certificates provided by the Wisconsin Bureau of Health Statistics for the years 1974-1978 and population data provided by the 1976 Survey of Income and Education were used to construct death rates. The death rates of the white civilian female population of Wisconsin 16-64 years of age were examined using exploratory data analysis techniques (schematic plots and median polish) and standard errors. In general, the death rates of women in the labor force are substantially lower than those of housewives. These results may indicate that the role of housewife exposes women to health hazards. In addition, the results of this study may suggest some selectivity of healthy women into the labor force or a protective effect of labor force participation. In a limited number of instances, labor force participants' mortality rates exceed those of housewives. In the 60-64 year old population, white-collar workers, specifically, sales workers, managers and professionals, experience significantly higher death rates than housewives. In addition, specific groups of labor force participants experience significantly higher death rates than housewives for accidental deaths (i.e. laborers 16-44 and 45-54), deaths due to heart disease (i.e. laborers 45-54 and sales workers 60-64) and deaths due to malignant neoplasms (i.e. white-collar workers 60-64 years of age). The possibility that these instances indicate the direction of future mortality trends should be considered.

Labor-force participation of older married women.

This article utilizes the 1969, 1971, and 1973 waves of the Longitudinal Retirement History Study (LRHS) to examine stopping work by working wives of respondents. Different patterns of labor-force participation reveal that younger wives of respondents were more likely to work than were older wives. Most wives did not reenter the labor force after leaving it. The determinants of stopping or continuing work in 1969-73 for those wives who worked in 1969 were also examined. Although the patterns were somewhat different for younger wives, two factors stand out: Coverage of the wife by a private pension plan and providing for children or elderly parents have substantial effects on the probability of continuing work.

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

Female labor force behavior and fertility in the United States.

respectively to 18.6% and 39.0% and by 1983 to 49.9% and 63.8%. The traditional pattern of post-school work, interruption of employment; and possibly a subsequent return to the labor force has been eroding, with women remaining more closely attached to the labor force during the childrearing years. If, as is likely, this trend continues, one may expect a move toward convergence in the male and female occupational distributions and a narrowing in the wage differential between the sexes. The implications that women's increased commitment to market activities may have in terms of income distribution among families and the quantity and quality of time spent on child care are less clear at the present time and require close attention. As Ryder (1980) documents, changes in the timing of births have come to be the primary driving force behind movements of period fertility in the US.

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

PubMed

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.

1994-09-01

The purpose of this study was to develop and evaluate a model of labor force participation among a group of older women in the United States. A comprehensive measure of women's combined work and family experiences across the adult life course was created. Employing data from the 1984 Survey of Income and Program Participation, we applied multinomial logistic regression techniques to examine the association between work-family experiences and later life labor supply. Our findings generally support an attachment hypothesis, showing that women who were the most work-oriented throughout the life course were more likely than women who experienced family-related spells of nonlabor-market activity to participate in the labor force, either full-time or part-time, later in life.

Objective To compare the costs of a protocol of active management of labor with those of traditional labor management. Design Cost analysis of a randomized controlled trial. Methods From August 1992 to April 1996, we randomly allocated 405 women whose infants were delivered at the University of New Mexico Health Sciences Center, Albuquerque, to an active management of labor protocol that had substantially reduced the duration of labor or a control protocol. We calculated the average cost for each delivery, using both actual costs and charges. Results The average cost for women assigned to the active management protocol was $2,480.79 compared with an average cost of $2,528.61 for women in the control group (P = 0.55). For women whose infant was delivered by cesarean section, the average cost was $4,771.54 for active management of labor and $4,468.89 for the control protocol (P = 0.16). Spontaneous vaginal deliveries cost an average of $27.00 more for actively managed patients compared with the cost for the control protocol. Conclusions The reduced duration of labor by active management did not translate into significant cost savings. Overall, an average cost saving of only $47.91, or 2%, was achieved for labors that were actively managed. This reduction in cost was due to a decrease in the rate of cesarean sections in women whose labor was actively managed and not to a decreased duration of labor. PMID:10778374

Effects of labor force participation on women's health: new evidence from a longitudinal study.

PubMed

Waldron, I; Jacobs, J A

1988-12-01

Effects of labor force participation on women's health are evaluated in analyses of longitudinal data for a national sample of older middle-aged women. Our findings indicate that labor force participation had beneficial effects on health for unmarried women and for married black women, but, on the average, labor force participation had no significant effect on health for married white women. Analyses by occupational category suggest that labor force participation had beneficial effects on health for some blue collar married women, but, on the average, labor force participation had harmful effects on health for white collar married women. Our findings, taken together with previous evidence, suggest that employment may increase social support, and job-related social support may have particularly beneficial effects on health for unmarried women and for married women whose husbands are not emotionally supportive confidants. Additional results from this study showed no significant difference in the health effects of part-time and full-time employment.

Mandatory retirement and labor-force participation of respondents in the Retirement History Study.

PubMed

Barker, D T; Clark, R L

1980-11-01

The Age Discrimination in Employment Act (ADEA) was amended in 1978 to prohibit mandatory retirement before age 70 in most occupations. The impact of this legislation on the probability of older persons remaining in the labor force is the primary concern of this article. Specifically, questions concerning which older workers are affected by mandatory-retirement provisions and the extent to which they are forced to retire and leave the labor force are examined. Tabular analysis of data from the Retirement History Study on persons aged 62-63 in 1969 shows significant variation in mandatory-retirement coverage between the public and private sectors and across industries, occupations, and demographic groups. Until age 65, the labor-force participation rate of those facing compulsory retirement is higher than or equal to that of those not covered but it drops significantly below the noncovered rate after 65. Logit analysis of the labor-force participation of persons before and after age 65 indicates that mandatory retirement at that age reduces the probability of retirement by approximately 16.7 percentage points for white men wage earners. This results in a decline in the labor-force participation rate of all men aged 66-67 of approximately 4 percentage points.

Background 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. Methods 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. Results 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.

The aims of this paper are to generate estimates of the association between the severity and frequency of pain in Spain and (i) labor force participation and workforce status and (ii) patterns of absenteeism and presenteeism for the employed workforce. Data are from the internet-based 2010 National Health and Wellness Survey (NHWS). This survey covers both those who report experiencing pain in the last month as well as the no-pain population. An estimated 17.25% of adults in Spain report experiencing pain in the past month. A series of regression models are developed with the no-pain group as the reference category. The impact of pain, categorized by severity and frequency, is assessed within a labor supply framework for (i) labor force participation and (ii) absenteeism and presenteeism. Both binomial and multinomial logistic models are estimated. The results demonstrate that severe and moderate pain has a significant, substantive, and negative association with labor force participation and, together with the experience of mild pain, a substantive impact on absenteeism and presenteeism within the employed workforce. Compared to no-pain controls, the strongest association is seen in the case of severe pain, notably severe daily pain and labor force participation (odds ratio 0.363; 95% CI: 0.206-0.637). The association of severe pain with labor force participation is also significant (odds ratio 0.356; 95% CI: 0.217-0.585). There is a clear gradient in the association of pain severity and frequency with labor force participation. The impact of pain is far greater than the potential impact of other health status measures (e.g., chronic comorbidities and BMI). Labor force participation is also adversely associated with pain experience. Persons reporting severe daily pain are far more likely not to be in the labor force (relative probabilities 0.339 vs 0.611). The experience of pain, notably severe and frequent pain, also outstrips the impact of other health status

Trends in female labor force participation in Sweden.

PubMed

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.

Why Japanese workers remain in the labor force so long: lessons for the United States?

PubMed

Williamson, John B; Higo, Masa

2009-12-01

As part of the search for ways to increase labor force participation rates among older workers in the United States, it makes sense to take a close look at evidence from Japan, one of the few industrial countries with a substantially higher labor force participation rate among older workers, particularly men, than the United States. Based mainly on prior studies and original interview data, we first discuss five potential factors which help explain why Japanese workers remain in the labor force as long as they do: (1) perceived economic necessity; (2) the large fraction of workers who are self-employed; (3) a culture that puts a high value on remaining in the labor force throughout the life course; (4) the long healthy life expectancy; and (5) the government's role in facilitating the labor force participation of older workers. We suggest that the Japanese national cultural value on remaining economically productive well into old age clearly underlies the development of the government's legislative initiatives aiming to extend the working lives of older workers. We then outline three policy suggestions for those seeking to increase labor force participation rates among older U.S. workers: (1) increase the financial incentive to workers who remain in the labor force; (2) improve public programs designed to foster efforts by older workers to become self-employed; and (3) increase the extent of government efforts to link older workers to prospective employers.

Unemployment, labor force composition and sickness absence: a panel data study.

PubMed

Askildsen, Jan Erik; Bratberg, Espen; Nilsen, Oivind Anti

2005-11-01

Sickness absence tends to be negatively correlated with unemployment rates. In addition to pure health effects, this may be due to moral hazard behavior by workers who are fully insured against income loss during sickness and to physicians who meet demand for medical certificates. Alternatively, it may reflect changes in the composition of the labor force, with more sickness-prone workers entering the labor force in upturns. A panel of Norwegian register data is used to analyze long-term sickness absences. The unemployment rate is shown to be negatively associated with the probability of absence, and with the number of days of sick leave. Restricting the sample to workers who are present in the whole sample period, the negative relationship between absence and unemployment becomes clearer. This indicates that procyclical variations in sickness absence are caused by established workers and not by the composition of the labor force.

The relationship between retirement life cycle changes and older men's labor force participation rates.

PubMed

Hayward, M D; Crimmins, E M; Wray, L A

1994-09-01

This study probes the utility of older men's labor force participation rates (LFPRs) as indicators of the work-to-retirement transition. Specific attention is directed at how shifts in the retirement life cycle are related to LFPRs. Based on Current Population Survey data for the 1970s, a life table modeling approach showed that LFPRs are relatively weak indicators of the work-to-retirement transition. This was demonstrated by the relative stability in older men's age profiles of LFPRs despite significant changes in the timing and "organization" of the work-to-retirement transition. The 1970s evidenced a contraction of the main career and the expansion of both post-retirement work activity and retirement, yet none of these changes substantially altered the age profiles of older men's labor force participation rates.

Outcomes of Nulliparous Women with Spontaneous Labor Onset Admitted to Hospitals in Pre-active versus Active Labor

Introduction The timing of when a woman is admitted to the hospital for labor care following spontaneous contraction onset may be among the most important decisions that labor attendants make as it can influence care patterns and birth outcomes. The aims of this study were to estimate the percentage of low-risk, nulliparous women at term who are admitted to labor units prior to active labor and to evaluate the effects of the timing of admission (i.e., pre-active versus active labor) on labor interventions and mode of birth. Methods Obstetrics data from low-risk, nulliparous women with spontaneous labor onset at term gestation (N = 216) were merged from two prospective studies conducted at three large, Midwestern hospitals. Baseline characteristics, labor interventions, and outcomes were compared between groups using Fisher’s exact and Mann-Whitney U tests, as appropriate. Likelihoods for oxytocin augmentation, amniotomy, and cesarean delivery were assessed by logistic regression. Results Of the sample of 216 low-risk nulliparous women, 114 (52.8%) were admitted in pre-active labor and 102 (47.2%) were admitted in active labor. Women admitted in pre-active labor were more likely to undergo oxytocin augmentation (84.2% and 45.1%, respectively; odds ratio (OR) 6.5, 95% confidence interval (CI) 3.43–12.27) but not amniotomy (55.3% and 61.8%, respectively; OR 0.8, 95% CI 0.44–1.32) when compared to women admitted in active labor. The likelihood of cesarean delivery was higher for women admitted before active labor onset (15.8% and 6.9%, respectively; OR 2.6, 95% CI 1.02–6.37). Discussion Many low-risk nulliparous women with regular, spontaneous uterine contractions are admitted to labor units before active labor onset, which increases their likelihood of receiving oxytocin and being delivered via cesarean section. An evidence-based, standardized approach for labor admission decision-making is recommended to decrease inadvertent admissions of women in pre-active

WORKING AND CARING: THE SIMULTANEOUS DECISION OF LABOR FORCE PARTICIPATION AND INFORMAL ELDERLY AND CHILD SUPPORT ACT IVITIES IN MEXICO*

PubMed Central

van Gameren, Edwin; Velandia Naranjo, Durfari

2016-01-01

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

Foreign workers in Kuwait: implications for the Kuwaiti labor force.

PubMed

Shah, N M

1986-01-01

An analysis of the foreign population in Kuwait shows that foreign nationals make up 60 percent of the population and 78 percent of the labor force in Kuwait. The implications of these figures for the Kuwaiti labor force are discussed by analyzing the occupational structures of Kuwaitis and non-Kuwaitis. "Structural analysis of the labor force indicates that 62 percent of Kuwaiti males are concentrated in administrative and service occupations while their percentage in sales and production work has declined during 1970-80. This demonstrates the need for reorienting educational/training programs and changing Kuwaiti attitudes towards manual work to ensure the realization of the 'Kuwaitization' process, and balance the nationals with foreign nationals." mortality has stabilized at relatively high levels and there is resistance to family planning. The author concludes that the main cause of the stalling of the demographic transition process is to be found in the role of the state and the dynamics of the social structure and that "demographic trends will depend more on the changes in social structure, land reforms, and response of the formal governing system to the needs of the underprivileged sections of the society, rather than on the health and family planning policies." excerpt

2012-06-01

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 < 0.0001). Further, those employed part-time with no chronic health condition were 48% less likely to be in poverty (OR: 0.52, 95% CI: 0.51-0.53, P < 0.0001) than those also employed part-time but with chronic back problems. It was found that among those with back problems, those out of the labor force were significantly more likely to be in 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.

Use of an Early Labor Lounge to Promote Admission in Active Labor.

Paul, Julie A; Yount, Susan M; Breman, Rachel Blankstein; LeClair, Melissa; Keiran, Diane M; Landry, Nannette; Dever, Kimberly

2017-03-01

Professional maternity care organizations within the United States are aligned in the goal to prevent the first cesarean birth in nulliparous women with a term, singleton, vertex fetus. Currently, one in 3 women are at risk for having a cesarean birth. The most common reason for cesarean in the United States is labor dystocia. The evidence supports delaying admission to the birthing unit until active labor is established, thereby minimizing the inadvertent diagnosis of labor dystocia. Providers are familiar with the rationale supporting delayed admission to the birthing unit until active labor is established; however, there is very little evidence on how to effectively promote this delay. Provider apprehension and the lack of early labor support are challenges to sending women home to await the onset of active labor. Maternal anxiety, fear, pain, and unpreparedness also play a part in this reluctance. To address these obstacles, South Shore Hospital created an early labor lounge with stations aimed at instilling confidence in the birth team, promoting teamwork, facilitating relaxation, and reducing anxiety for laboring women. A literature review focusing on women's perceptions of promoting admission in active labor, maternal anxiety, and nonpharmacologic strategies for managing early labor are discussed within the context of the creation, implementation, and evaluation of an early labor lounge. © 2017 by the American College of Nurse-Midwives.

Are we getting healthier as we grow older? Implications for babyboomer labor force participation.

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.

2009-01-01

The unprecedented aging of the world's population challenges many institutions, including labor markets and public pension programs. This study was conducted to survey expert opinions regarding conditions and policies that affect employment of older adults. Eighty-nine respondents from 26 nations responded to an Internet survey regarding their own experiences with the aging labor force; factors that encouraged or discouraged labor force participation of older adults; and government responses to these issues. Respondents identified barriers to employment of older adults and described their governments' responses. Findings illuminate a range of current policy options and suggest possible opportunities for innovation.

Mental health and the labor force participation of older workers.

PubMed

Mitchell, J M; Anderson, K H

1989-01-01

Over the past 20 years, while mortality rates have dramatically declined, the prevalence of work-related stress has increased. This phenomenon suggests that the population's physical health has improved, but mental health has deteriorated. Concomitantly, fewer older workers are participating in the labor force. Our paper, using data from the Epidemiologic Catchment Area (ECA) program, assesses whether the decline in numbers of older workers is linked to the increasing prevalence of job-related stress. Our results indicate that symptoms of poor mental health are the most important determinants of work behavior. Surprisingly, economic and demographic characteristics appear to have little impact on an individual's labor force participation status. Further research is needed, however, because the ECA data provides insufficient information to accurately assess the relative importance of both mental health and economic factors on the retirement decision.

Labor force participation among persons with musculoskeletal conditions, 1970-1987. National estimates derived from a series of cross-sections.

PubMed

Yelin, E H; Katz, P P

1991-11-01

In the present study, we estimated the labor force participation rate among persons with musculoskeletal conditions in 1987, compared this rate with that experienced by persons with other chronic conditions or with none, and estimated the change in labor force participation rates among persons with musculoskeletal conditions for the period 1970-1987. Rates were estimated from 18 years of National Health Interview Survey data, and the sampling weights from this survey were used to obtain population estimates. To ensure statistically stable estimates, we averaged the rates over 6 years of data. In 1987, 42.9% of all working-age persons with musculoskeletal conditions were out of the labor force, this study's definition of work disability. Overall labor force participation rates among persons with musculoskeletal conditions declined from 71% to 56% between 1976-1981 and 1982-1987, 22% in relative terms. Much of this decline was concentrated among men, especially men 55-64 years of age. However, women 55-64 years of age with musculoskeletal conditions also experienced declining labor force participation rates. Labor force participation patterns among persons with musculoskeletal conditions fit more general labor market trends, with gains among younger women more than offset by declines among older men and women. However, these trends appear to be more accentuated among persons with musculoskeletal conditions, suggesting that enforcement of the employment provisions of the Americans with Disabilities Act of 1990 place special emphasis on labor force participation among such persons.

As people continue to age and receive complex health care services at home, concern has arisen about the availability of family caregivers and their ability to combine employment with caregiving. This article evaluates the international research on unpaid caregivers and their labor market choices, highlighting three conclusions: first, caregivers in general are equally as likely to be in the labor force as noncaregivers; second, caregivers are more likely to work fewer hours in the labor market than noncaregivers, particularly if their caring commitments are heavy; and finally, only those heavily involved in caregiving are significantly more likely to withdraw from the labor market than noncaregivers. Policy recommendations are targeting greater access to formal care for "intensive" caregivers and developing workplace policies for employed caregivers.

Who needs 'lazy' workers? Inactive workers act as a 'reserve' labor force replacing active workers, but inactive workers are not replaced when they are removed.

PubMed

Charbonneau, Daniel; Sasaki, Takao; Dornhaus, Anna

2017-01-01

Social insect colonies are highly successful, self-organized complex systems. Surprisingly however, most social insect colonies contain large numbers of highly inactive workers. Although this may seem inefficient, it may be that inactive workers actually contribute to colony function. Indeed, the most commonly proposed explanation for inactive workers is that they form a 'reserve' labor force that becomes active when needed, thus helping mitigate the effects of colony workload fluctuations or worker loss. Thus, it may be that inactive workers facilitate colony flexibility and resilience. However, this idea has not been empirically confirmed. Here we test whether colonies of Temnothorax rugatulus ants replace highly active (spending large proportions of time on specific tasks) or highly inactive (spending large proportions of time completely immobile) workers when they are experimentally removed. We show that colonies maintained pre-removal activity levels even after active workers were removed, and that previously inactive workers became active subsequent to the removal of active workers. Conversely, when inactive workers were removed, inactivity levels decreased and remained lower post-removal. Thus, colonies seem to have mechanisms for maintaining a certain number of active workers, but not a set number of inactive workers. The rapid replacement (within 1 week) of active workers suggests that the tasks they perform, mainly foraging and brood care, are necessary for colony function on short timescales. Conversely, the lack of replacement of inactive workers even 2 weeks after their removal suggests that any potential functions they have, including being a 'reserve', are less important, or auxiliary, and do not need immediate recovery. Thus, inactive workers act as a reserve labor force and may still play a role as food stores for the colony, but a role in facilitating colony-wide communication is unlikely. Our results are consistent with the often cited, but never

The impact of work-limiting disability on labor force participation.

PubMed

Webber, Douglas A; Bjelland, Melissa J

2015-03-01

According to the justification hypothesis, non-employed individuals may over-report their level of work limitation, leading to biased census/survey estimates of the prevalence of severe disabilities and the associated labor force participation rate. For researchers studying policies which impact the disabled or elderly (e.g., Supplemental Security Income, Disability Insurance, and Early Retirement), this could lead to significant bias in key parameters of interest. Using the American Community Survey, we examine the potential for both inflated and deflated reported disability status and generate a general index of disability, which can be used to reduce the bias of these self-reports in other studies. We find that at least 4.8 million individuals have left the labor force because of a work-limiting disability, at least four times greater than the impact implied by our replication of previous models.

Labor force participation at older ages in the Western Pacific: A microeconomic analysis.

PubMed

Agree, E M; Clark, R L

1991-10-01

Retirement has become a very important stage of life for persons in developed countries. Life expectancy for those over age 60 has increased markedly. Rising real income and the institution of broad based social security systems have encouraged older workers to leave the labor force at younger ages. p]Reductions in older age mortality have also affected the less developed regions. Increases in the number of older persons, coupled with continuing high fertility, have increased the size of the working age population through both large entry cohorts and longevity of current workers. The capacity of the economy to absorb this growth is severely limited. As a result, labor force decisions by older individuals will be of increasing importance.This study provides new evidence on labor force decisions in four developing countries in the Western Pacific: Fiji, the Republic of Korea, Malaysia, and the Philippines. A uniform survey sponsored by the World Health Organization in the four countries of persons aged 60 and over is employed to estimate the determinants of work decisions.

Welfare Reform and Labor Force Exit by Young, Low-Skilled Single Males.

PubMed

Groves, Lincoln H

2016-04-01

While the labor market woes of low-skilled male workers in the United States over the past several decades have been well documented, the academic literature identifying causal factors leading to declines in labor force participation (LFP) by young, low-skilled males remains scant. To address this gap, I use the timing and characteristics of welfare-reform policies implemented during the 1990s and fixed-effects, instrumental variable regression modeling to show that policies seeking to increase LFP rates for low-skilled single mothers inadvertently led to labor force exit by young, low-skilled single males. Using data from the Current Population Survey and a bundle of work inducements enacted by states throughout the 1990s as exogenous variation in a quasi-experimental design, I find that the roughly 10 percentage point increase in LFP for low-skilled single mothers facilitated by welfare reform resulted in a statistically significant 2.8 percentage point decline in LFP for young, low-skilled single males. After conducting a series of robustness checks, I conclude that this result is driven entirely by white males, who responded to welfare-reform policies with a 3.7 percentage point decline in labor supply. Young black males, as well as other groups of potentially affected workers, appear to be uninfluenced by the labor supply response of less-educated single mothers to welfare reform. Impacts on young, single white males are large and economically significant, suggesting that nearly 150,000 males departed the formal labor market in response to directed welfare-reform policies.

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.

Education, labor-force participation, and fertility in the USSR.

PubMed

Berliner, J S

1983-01-01

The effect of education on Soviet fertility and female labor participation is analyzed in terms of the neoclassical theory of the household. Using this theory, child worth in terms of services and real consumption or distribution of income are analyzed as factors in fertility decision making. The hypotheses are tested by multivariate analysis of Soviet census data. The contribution of husband and wife to family income is different from that in the West. The effect of female education on fertility should be in the range of small and negative to moderately positive. The effect of male education should be moderately negative. The effect of an individual family's education level on its fertility is often influenced by the community's education level. Rising educational levels of males have contributed most to the decline of Soviet fertility recently. The rising education of females has tended to offset this negative influence, however. The rural Soviet data support this. The female labor-force participation rates are negative and significant. Of the total (positive) effect of female higher education on fertility; half operates indirectly-by decreasing labor participation which in turn increases fertility. The other half affects fertility directly. These results imply a backward-bending female labor supply curve at the higher education level.

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.

The Spatial and Career Mobility of China's Urban and Rural Labor Force.

Hao, Lingxin; Liang, Yucheng

2016-03-01

This paper provides a comprehensive examination of the spatial and career mobility of China's labor population. The paper integrates theories on stratification and social change and exploits the innovative design and measurement of the China Labor-force Dynamics Survey to minimize the under-coverage problem of the rural-urban migratory experience. Our analysis provides several fresh findings: (1) at-birth rural household registration (hukou) status leads to a greater probability of spatial mobility and career advancement than at-birth urban hukou status does; (2) education and gender differentiates rural-origin people, increasing the heterogeneity of urban labor and decreasing the heterogeneity of rural labor; (3) hukou policy relaxation favors later cohorts over earlier cohorts; and (4) among demographically comparable people, having experienced spatial mobility is correlated with having career advancement experience. Work organizations are found to be the arena where the two dimensions of mobility can happen jointly. Our findings provide a rich context for understanding the management and organization of Chinese labor.

Uterine electrical activity is correlated to the appearance of uterine contractions. forceful contractions appear at the end of term. Therefore, understanding the genesis and the propagation of uterine electrical activity may provide an efficient tool to diagnose preterm labor. Moreover, the control of uterine excitability seems to have important consequences in the control of preterm labor. Modeling the electrical activity in uterine tissue is thus an important step in understanding physiological uterine contractile mechanisms and to permit uterine EMG simulation. Our model presented in this paper, incorporates ion channel models at the cell level, the reaction diffusion equations at the tissue level and the spatiotemporal integration at the uterine EMG reconstructed level. This model validates some key physiological observation hypotheses concerning uterine excitability and propagation.

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.

The Spatial and Career Mobility of China’s Urban and Rural Labor Force*

PubMed Central

Hao, Lingxin; Liang, Yucheng

2017-01-01

This paper provides a comprehensive examination of the spatial and career mobility of China’s labor population. The paper integrates theories on stratification and social change and exploits the innovative design and measurement of the China Labor-force Dynamics Survey to minimize the under-coverage problem of the rural-urban migratory experience. Our analysis provides several fresh findings: (1) at-birth rural household registration (hukou) status leads to a greater probability of spatial mobility and career advancement than at-birth urban hukou status does; (2) education and gender differentiates rural-origin people, increasing the heterogeneity of urban labor and decreasing the heterogeneity of rural labor; (3) hukou policy relaxation favors later cohorts over earlier cohorts; and (4) among demographically comparable people, having experienced spatial mobility is correlated with having career advancement experience. Work organizations are found to be the arena where the two dimensions of mobility can happen jointly. Our findings provide a rich context for understanding the management and organization of Chinese labor. PMID:29129981

Health sector employment growth calls for improvements in labor productivity.

PubMed

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.

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.

Gender hierarchies in the health labor force.

PubMed

Butter, I H; Carpenter, E S; Kay, B J; Simmons, R S

1987-01-01

Rapid growth and increasing diversity characterize trends of the U.S. health labor force in recent decades. While these trends have promoted change on many different fronts of the health system, hierarchical organization of the health work force remains intact. Workers continue to be stratified by class and race. Superimposed on both strata is a structure that segregates jobs by gender, between and within health occupations. While female health workers outnumber males by three to one, they remain clustered in jobs and occupations lower in pay, less prestigious, and less autonomous than those of their male counterparts. What has prevented women from improving their economic and leadership status as health workers? Is work performed by men of higher prestige because men perform it? Would curative and technical fields have less status if dominated by women? Would health promotion be funded more generously if most health educators were men? In this article, two analytical constructs are presented to take a closer look at occupational categories, selected structural characteristics, differential rewards, and their relationship to gender segregation. Taken together, they demonstrate how women always cluster at the bottom and men at the top, no matter which dimension is chosen.

Caretaking as articulation work: the effects of taking up responsibility for a child with asthma on labor force participation.

PubMed

Timmermans, Stefan; Freidin, Betina

2007-10-01

A well-established quantitative literature has documented the financial toll for women's caretaking. Still, we do not know much about the process by which women end up taking on an extensive caretaking role and what they do on a daily basis. Based on in-depth interviews with a convenience sample of fifty caretakers of school aged children with asthma and nine health professionals in the USA, this study examines how health professionals socialize mothers into an intensive caretaking role for their children with asthma, how mothers negotiated and perform that role, and the impact of care work on their labor force participation. Care providers assign broad caretaking tasks that require further articulation work to get the job done. Although mothers care for their children in varied ways, caring for a child with a chronic disease remains a time-consuming activity. Mothers pay a price for the indeterminate nature of articulation work by scaling back their involvement in the paid labor force.

Labor force participation, unemployment and occupational attainment among immigrants in West European countries

PubMed Central

Semyonov, Moshe

2017-01-01

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. PMID:28475632

The aims of this paper are to generate estimates of the association between the experience and burden of pain, by severity and frequency, with (1) labor force participation and workforce status in five EU countries (the UK, France, Spain, Germany and Italy) and (2) patterns of absenteeism and presenteeism for the employed workforce. Data are from the internet-based 2008 National Health and Wellness Survey (NHWS). This survey covers both those who report experiencing pain in the last month as well as the no pain population. A series of regression models are developed with the no pain group as the reference category. The impact of pain, categorized by severity and frequency reported, is assessed within a labor supply framework for (1) labor force participation and (2) absenteeism and presenteeism. In the former case both binomial and multinomial logistic models are estimated; in the latter case ordered logit models are estimated. The results demonstrate that, in the context of health status, the experience of frequent severe and moderate pain has a dominant, independent and negative association with labor force participation and employment status as well as absenteeism and presenteeism. The presence of severe daily pain is associated with a 20-point reduction in the probability of being employed full-time; with moderate daily pain associated with a 10-point reduction. The impact of pain is far greater than the potential impact of other health status measures (e.g., chronic comorbidities and BMI). The experience of pain, notably severe and frequent pain, also outstrips the impact of other health status factors in absenteeism and presenteeism. The experience of pain, in particular severe daily pain, has a substantial negative association with labor force participation in these five European countries as well as reported absenteeism and presenteeism. As a measure of health status, it clearly outweighs other health status measures. Whether or not pain is considered as a

Widowhood, sex, labor force participation, and the use of physician services by elderly adults.

Homan, S M; Haddock, C C; Winner, C A; Coe, R M; Wolinsky, F D

1986-11-01

This paper investigated the relationships of widowhood, sex, and labor force participation with the use of ambulatory physician services by elderly adults. Data on 18,441 individuals aged 55 and over were taken from the 1978 Health Interview Survey. Hierarchical regression results indicated that although these three factors are related to physician utilization at the zero- and first-partial levels, only sex remained significant when their two- and three-way interactions and other variables from the behavioral model (including living arrangements) were introduced. This suggests that the effects of widowhood and labor force participation are spurious. Widows are simply more likely to live alone and are less likely to work than widowers; those who live alone and do not work are more likely to use health services (and more of them) than those who live with others and are gainfully employed.

Friedman, the United Kingdom's National Institute for Health and Care Excellence (NICE), and the American College of Obstetricians and Gynecologists/Society for Maternal-Fetal Medicine (ACOG/SMFM) support different active labor diagnostic guidelines. Our aims were to compare likelihoods for cesarean delivery among women admitted before vs in active labor by diagnostic guideline (within-guideline comparisons) and between women admitted in active labor per one or more of the guidelines (between-guideline comparisons). Active labor diagnostic guidelines were retrospectively applied to cervical examination data from nulliparous women with spontaneous labor onset (n = 2573). Generalized linear models were used to determine outcome likelihoods within- and between-guideline groups. At admission, 15.7%, 48.3%, and 10.1% of nulliparous women were in active labor per Friedman, NICE, and ACOG/SMFM diagnostic guidelines, respectively. Cesarean delivery was more likely among women admitted before vs in active labor per the Friedman (AOR 1.75 [95% CI 1.08-2.82] or NICE guideline (AOR 2.55 [95% CI 1.84-3.53]). Between guidelines, cesarean delivery was less likely among women admitted in active labor per the NICE guideline, as compared with the ACOG/SMFM guideline (AOR 0.55 [95% CI 0.35-0.88]). Many nulliparous women are admitted to the hospital before active labor onset. These women are significantly more likely to have a cesarean delivery. Diagnosing active labor before admission or before intervention to speed labor may be one component of a multi-faceted approach to decreasing the primary cesarean rate in the United States. The NICE diagnostic guideline is more inclusive than Friedman or ACOG/SMFM guidelines and its use may be the most clinically useful for safely lowering cesarean rates. © 2017 Wiley Periodicals, Inc.

Statistical aspects of modeling the labor curve.

PubMed

Zhang, Jun; Troendle, James; Grantz, Katherine L; Reddy, Uma M

2015-06-01

In a recent review by Cohen and Friedman, several statistical questions on modeling labor curves were raised. This article illustrates that asking data to fit a preconceived model or letting a sufficiently flexible model fit observed data is the main difference in principles of statistical modeling between the original Friedman curve and our average labor curve. An evidence-based approach to construct a labor curve and establish normal values should allow the statistical model to fit observed data. In addition, the presence of the deceleration phase in the active phase of an average labor curve was questioned. Forcing a deceleration phase to be part of the labor curve may have artificially raised the speed of progression in the active phase with a particularly large impact on earlier labor between 4 and 6 cm. Finally, any labor curve is illustrative and may not be instructive in managing labor because of variations in individual labor pattern and large errors in measuring cervical dilation. With the tools commonly available, it may be more productive to establish a new partogram that takes the physiology of labor and contemporary obstetric population into account.

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

NASA Astrophysics Data System (ADS)

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.

Labor-Force Participation, Policies & Practices in an Aging America: Adaptation Essential for a Healthy & Resilient Population.

PubMed

Berkman, Lisa F; Börsch-Supan, Axel; Avendano, Mauricio

2015-01-01

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.

Objectives To determine if labor-associated inflammatory markers differ between low-risk, nulliparous women in pre-active vs. active labor at hospital admission and over time. Study Design Prospective comparative study of low-risk, nulliparous women with spontaneous labor onset at term (N=118) sampled from two large Midwestern hospitals. Circulating concentrations of inflammatory markers were measured at admission and again 2 and 4 hours later: namely, neutrophil and monocyte counts; and serum inflammatory cytokines (interleukin [IL]-1β, IL-6, tumor necrosis factor [TNF]-α, IL-10) and chemokines (IL-8). Biomarker concentrations and their patterns of change over time were compared between pre-active (n=63) and active (n=55) labor admission groups using Mann-Whitney U tests. Results Concentrations of IL-6 and IL-10 in the active labor admission group were significantly higher than concentrations in the pre-active labor admission group at all three time points. Neutrophil levels were significantly higher in the active group at 2 and 4 hours after admission. The rate of increase in neutrophils and IL-10 between admission and 2 hours later was faster in the active group (p<0.001 and p=0.003, respectively). Conclusions Circulating concentrations of several inflammatory biomarkers are higher and their rate of change over time since admission is faster among low-risk, nulliparous women admitted to hospitals in active labor, as compared to those admitted in pre-active labor. More research is needed to determine if progressive changes in inflammatory biomarkers might be a useful adjunct to improving the assessment of labor progression and determining the optimal timing of labor admission.

Se analizan los factores determinantes de la participación en la fuerza de trabajo de la póblacion mexicana de 50 años o más, con datos de la Encuesta nacional sobre salud y envejecimiento en México, ENASEM. Se estudió en particular la importancia de la salud en la decisión sobre la participación, tomando en cuenta la endogeneidad potencial de la salud. Los resultados indican que una mejor salud causa un mayor apego al mercado laboral. No se encontró evidencia clara de que el empleo afecte la salud, pero no puede descartarse que los efectos de las malas condiciones laborales y la justificación se eliminen mutuamente. Existen indicadores de que la autoevaluación de la salud no captura todos los aspectos relevantes de la salud. En la toma de decisiones para establecer políticas, la importancia directa de las circunstancias financieras podría ser más relevante que el papel de la salud. The determinants of the labor force participation of people in Mexico aged 50 and over are analyzed using data of the Mexican Health and Aging Study (MHAS). In particular we study the importance of health in the participation decision, taking into account the potential endogeneity of health. The results indicate that a better health causes a stronger attachment to the labor market. We find no clear evidence that employment affects health, but it cannot be ruled out that the effects of bad labor circumstances and justification eliminate each other. There are indications that self-assessed health does not capture all relevant aspects of health. For policy decisions the direct importance of financial circumstances could be more relevant than the role of health. PMID:29375171

Se analizan los factores determinantes de la participación en la fuerza de trabajo de la póblacion mexicana de 50 años o más, con datos de la Encuesta nacional sobre salud y envejecimiento en México, ENASEM. Se estudió en particular la importancia de la salud en la decisión sobre la participación, tomando en cuenta la endogeneidad potencial de la salud. Los resultados indican que una mejor salud causa un mayor apego al mercado laboral. No se encontró evidencia clara de que el empleo afecte la salud, pero no puede descartarse que los efectos de las malas condiciones laborales y la justificación se eliminen mutuamente. Existen indicadores de que la autoevaluación de la salud no captura todos los aspectos relevantes de la salud. En la toma de decisiones para establecer políticas, la importancia directa de las circunstancias financieras podría ser más relevante que el papel de la salud. The determinants of the labor force participation of people in Mexico aged 50 and over are analyzed using data of the Mexican Health and Aging Study (MHAS). In particular we study the importance of health in the participation decision, taking into account the potential endogeneity of health. The results indicate that a better health causes a stronger attachment to the labor market. We find no clear evidence that employment affects health, but it cannot be ruled out that the effects of bad labor circumstances and justification eliminate each other. There are indications that self-assessed health does not capture all relevant aspects of health. For policy decisions the direct importance of financial circumstances could be more relevant than the role of health.

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.

Should I stay or should I go? Career change and labor force separation among registered nurses in the U.S.

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.

Labor force participation and human capital increases in an aging population and implications for U.S. research investment.

The proportion of the United States labor force >/=65 years of age is projected to increase between 2004 and 2014 by the passing of age 65 of the large post-World War II baby boom cohorts starting in 2010 and their greater longevity, income, education, and health [Toossi M (2005) Mon Labor Rev 128(11):25-44]. The aging of the U.S. labor force will continue to at least 2034, when the largest of the baby boom cohorts reaches age 70. Thus, the average health and functional capacity of persons age 65+ must improve for sufficient numbers of elderly persons to be physically and cognitively capable of work. This will require greater investments in research, public health, and health care. We examine how disability declines and improved health may increase human capital at later ages and stimulate the growth of gross domestic product and national wealth.

Fertility and patterns of labor force participation among married women.

PubMed

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

2015-01-01

Background Although 1-in-5 adults have multiple (≥2) chronic conditions, limited attention has been given to the association between multiple chronic conditions and employment. Methods Cross-sectional data (2011 National Health Interview Survey) and multivariate regression analyses were used to examine the association among multiple chronic conditions, employment, and labor force outcomes for U.S. adults aged 18–64 years, controlling for covariates. Results Among U.S. adults aged 18–64 years (unweighted n=25,458), having multiple chronic conditions reduced employment probability by 11%–29%. Some individual chronic conditions decreased employment probability. Among employed adults (unweighted n=16,096), having multiple chronic conditions increased the average number of work days missed due to injury/illness in the past year by 3–9 days. Conclusions Multiple chronic conditions are be a barrier to employment and increase the number of work days missed, placing affected individuals at a financial disadvantage. Researchers interested in examining consequences of multiple chronic conditions should give consideration to labor force outcomes. PMID:26103096

Labor-Force Dynamics at Older Ages

Zissimopoulos, Julie M.; Karoly, Lynn A.

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.

Physical activity during pregnancy has numerous benefits, but the influence on the duration of labor is unclear. We investigated the influence of habitual physical activity during late pregnancy on the duration of labor, with consideration of previous delivery experience and the stage of labor. This prospective study included 103 women (48 nulliparous, 55 multiparous) in late pregnancy. Habitual physical activity was evaluated using the Baecke physical activity questionnaire (BQ). Women were divided into a high activity group (HA) and a low activity group (LA) based on their median total BQ score. Data pertaining to the duration of labor were obtained from the birth records after delivery. In multiparous women, the duration of the second stage of labor was significantly shorter in the HA group than in the LA group [median (range): HA, 11 min (1-102 min); LA, 20 min (4-175 min); P < .05]. The significant difference persisted after adjusting for confounding variables (standardized β = -0.34; P = .01). In nulliparous women, there were no significant differences in duration of labor between groups. Higher physical activity in multiparous women during late pregnancy might positively influence the duration of the second stage of labor.

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.

Dystocia is the most common indication of primary cesarean section. The most common cause of dystocia is uterine dysfunction. In prolonged labor, more attention is usually paid to the fetus and pelvis rather than to the role of uterine contractions in a delivery. Therefore, we decided to determine the relationship between the labor progress and uterine contractions shapes. In this cross-sectional study, 200 primiparous women participated having a single pregnancy and cephalic presentation. Uterus contractions were recorded using electronic fetal monitoring at the beginning of the active phase of labor (dilatation 3-5 cm) for 30 min. Fall to rise (F:R) ratio was calculated by determining the duration of returning from a contraction peak to its baseline (fall) and the duration of the rise time from baseline to peak (rise) in two groups. The data were analyzed using t-test and Chi-square test. In this study, 162 women had a normal delivery and 38 women had a cesarean (CS) delivery due to the lack of labor progress. The average F:R ratio was 1.13±0.193 seconds in the vaginal delivery group and 1.64±0.301 seconds in the CS group. This difference was statistically significant (P<0.001). The frequency of contractions in the vaginal delivery group was more than the CS group (P=0.008). Our findings demonstrated that uterine contractions shapes change; and F:R ratio was higher in the group that lacked labor progress. Therefore, contraction shapes can be used to predict the labor progress.

Labor-Force Participation, Policies & Practices in an Aging America: Adaptation Essential for a Healthy & Resilient Population

Berkman, Lisa F.; Börsch-Supan, Axel; Avendano, Mauricio

2016-01-01

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. PMID:28042166

There are a wide variety of non- pharmacologic pain relief techniques for labor which include pelvic movement, upright position, back massage and partner support during the first stage of labor. The effectiveness of dance labor- which is a combination of these techniques- has not been evaluated. This study aimed to evaluate the effectiveness of dance labor in pain reduction and woman's satisfaction during the first stage of labor. 60 primiparous women aged 18-35 years old were randomly assigned to dance labor and control groups. In the dance labor group, women were instructed to do standing upright with pelvic tilt and rock their hips back and forth or around in a circle while their partner massaged their back and sacrum for a minimum of 30 minutes. In the control group, the participants received usual care during physiologic labor. Pain and satisfaction scores were measured by Visual Analogue Scale. Data were analyzed by using the t. test and Chi-square. Mean pain score in the dance labor group was significantly lower than the control group (P < 0.05). The mean satisfaction score in the dance labor group was significantly higher than in the control group (P < 0.05). Dance labor which is a complementary treatment with low risk can reduce the intensity of pain and increase mothers, satisfaction with care during the active phase of labor.

2016-02-01

In a prospective study in a tertiary university hospital we wanted to determine whether uterine electromyography (EMG) can differentiate between the active and latent phase of labor. Thirty women presenting at ≥37(0/7) weeks of gestation with regular uterine contractions, intact membranes, and a Bishop score <6. EMG was recorded from the abdominal surface for 30 min. Latent phase was defined as no cervical change within at least 4 h. Student's t-test was used for statistical analysis (p ≤ 0.05 significant). Diagnostic accuracy of EMG was determined by receiver operator characteristics (ROC) analysis. The integral of the amplitudes of the power density spectrum (PDS) corresponding to the PDS energy within the "bursts" of uterine EMG activity was compared between the active and latent labor groups. Seventeen (57%) women were found to be in the active phase of labor and 13 (43%) were in the latent phase. The EMG PDS integral was significantly higher (p = 0.02) in the active (mean 3.40 ± 0.82 μV) compared with the latent (mean 1.17 ± 0.33 μV) phase of labor. The PDS integral had an area under the ROC curve (AUC) of 0.80 to distinguish between active and latent phases of labor, compared with number of contractions on tocodynamometry (AUC = 0.79), and Bishop score (AUC = 0.78). The combination (sum) of PDS integral, tocodynamometry, and Bishop score predicted active phase of labor with an AUC of 0.90. Adding uterine EMG measurements to the methods currently used in the clinics could improve the accuracy of diagnosing active labor. © 2015 Nordic Federation of Societies of Obstetrics and Gynecology.

Corruption and economic growth with non constant labor force growth

NASA Astrophysics Data System (ADS)

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.

This quasi-experimental study was conducted by using an equivalent comparison group ( n = 40). The participants in the experimental group whose cervical dilation was 5 cm were taken to the hydrotherapy tub. This application continued until cervical dilation reached 10 cm. The Participants Questionnaire, The Birth Follow-up Questionnaire, The Postpartum ]collection tools. The duration of the active phase and second stage of labor was extremely short in the experimental group in comparison with the equivalent comparison group ( p = .001). The Visual Analogue Scale (VAS) scores of the experimental group were lower than those of the equivalent comparison group when cervical dilation was 6 cm and 10 cm ( p = .001). The experimental group also displayed more positive parenting behavior and positive labor feeling ( p = .001).

OBJECTIVE To evaluate whether beta-2 adrenoceptor genotype at a functional polymorphic site encoding for amino acid residue 16 influences rate of cervical dilatation in term and late preterm active labor. STUDY DESIGN Subjects that underwent vaginal delivery at 34 or greater weeks gestational age between May, 2006, and August, 2007, were identified. Each subject had provided venous blood from which DNA was extracted for beta-2 adrenoceptor genotyping. Digital cervical examinations with paired examination times were collected from intrapartum records. Rate of cervical dilatation in active labor was determined using linear regression and rates were compared between genotype groups. RESULTS Among 401 subjects with satisfactory genotype and intrapartum data, overall rate of active labor was 0.76+/−0.01 cm/hr. When labor was compared by genotype, homozygous Arg/Arg16 subjects progressed at a slower rate (0.64+/−0.03 cm/hr) than all other pooled genotypes (0.8+/−0.02 cm/hr). CONCLUSION Homozygous beta-2 adrenoceptor genotype encoding for Arg/Arg16 was associated with slower progress in active labor. PMID:21600547

Migraine headache and labor market outcomes.

While migraine headache can be physically debilitating, no study has attempted to estimate its effects on labor market outcomes. Using data drawn from the National Longitudinal Study of Adolescent Health, we estimate the effect of being diagnosed with migraine headache on labor force participation, hours worked, and wages. Ordinary least squares (OLS) estimates suggest that migraines are associated with reduced labor force participation and lower wages among females. A negative association between migraine headache and the wages of female respondents is also obtained using an instrumental variables (IV) approach, although the IV estimates are imprecise relative to the OLS estimates.

produced 15% of its wealth. There are also sharp contrasts in participation in the labor force. In less developed countries more youths and older persons are in the labor force while in developed countries more women work. By the year 2000 female activity rates in more developed regions will increase for ages 20-64 and decrease for those under 20 and over 64. This will raise female participation in the labor force to 35%. In less developed regions female participation is expected to decline. The proportion of young workers is expected to increase in less developed and decline in more developed regions; the same will be true for older workers. The dependency burden will be concentrated among the young in less developed nations; in more devel oped regions there will be larger numbers of older dependents.

The Angle Labor Pain Questionnaire (A-LPQ) is a new, 22-item multidimensional psychometric questionnaire that measures the 5 most important dimensions of women's childbirth pain experiences using 5 subscales: The Enormity of the Pain, Fear/Anxiety, Uterine Contraction Pain, Birthing Pain, and Back Pain/Long Haul. Previous work showed that the A-LPQ has overall good psychometric properties and performance during early active labor in women without pain relief. The current study assessed the tool's sensitivity to change during initiation of labor epidural analgesia with the standardized response mean (SRM, primary outcome). Two versions of the A-LPQ were administered once, in each of 2 test sessions, by the same trained interviewer during early active labor. The sequence of administration was randomized (ie, standard question order version [Test 1] followed by mixed version [Test 2] or vice versa). Test 1 was completed before epidural insertion; Test 2 commenced 20 to 30 minutes after the test dose. Providers assessed/treated pain independently of the study. Sensitivity to change was assessed using SRMs, Cohen's d, and paired t tests. Overall pain intensity was concurrently examined using Numeric Rating Scale and the Verbal Rating Scale (VRS); coping was assessed with the Pain Mastery Scale. Changes in pain were measured with the Patient Global Impression of Change Scale. Internal consistency was assessed with Cronbach's α. Concurrent validity with other tools was assessed using Spearman's rank correlation coefficient. A total of 51 complete datasets were analyzed. Most women reported moderate (63%, 32/51) or severe (18%, 9/51) baseline pain on VRS scores during Test 1; 29% (15/51) reported mild pain, and 6% (3/51) reported moderate pain during Test 2. Approximately 90% (46/51) of women reported much or very much improved pain at the end of testing. Cronbach's α for A-LPQ summary scores was excellent (0.94) and ranged from 0.78 (acceptable) to 0.92 (excellent) for

To obtain and study new data on the dynamics of the labor process and to develop a contraction-based index of labor progress. This study was carried out at the Delivery Room, Department of Obstetrics and Gynecology, Western Galilee Hospital, Nahariya, Israel, using a new device (Birth Track). We continuously monitored cervical dilatation (CD) and head descent (HD) in 30 nulliparaous women during active labor with (augmented group) and without (study group) oxytocin augmentation. This led to the development and validation of progress indices based on features extracted from continuous monitoring. There were no significant differences between the average of each parameter in the study and augmented groups, except for HD velocity. Average HD velocity was faster in the study group. Linear regression analyses demonstrated that head station (HS) amplitude and Toco amplitude were the best parameters for predicting HD velocity in both groups. In the study group, average HD velocity was also significantly related to Toco rate and contraction efficiency. In the augmented group, only a weak correlation with Toco rate was seen, and no correlation with contraction efficiency. With the assistance of the Birth Track device, we can obtain continuous data on the labor process and indices to estimate the labor progress process without the use of vaginal (manual) examination. © 2013 The Authors.

Early Claiming of Social Security Benefits and Labor Supply Behavior of Older Americans.

PubMed

Benítez-Silva, Hugo; Heiland, Frank

2008-12-01

The labor supply incentives provided by the early retirement rules of the United States Social Security Old Age benefits program are of growing importance as the Normal Retirement Age (NRA) increases to 67, and the labor force participation of Older Americans starts to increase. These incentives allow individuals who claim benefits before the NRA but continue to work, or return to the labor force, to increase their future rate of benefit pay by having benefits withheld. Since the adjustment of the benefit rate takes place only after the NRA is reached, benefits received before the NRA can become actuarially unfair for those who continue to work after claiming. Consistent with these incentives, estimates from bivariate models of the monthly labor force exit and claiming hazards using data from the Health and Retirement Study indicate that early claimers who do not withdraw from the labor force around the time they claim are increasingly likely to stay in the labor force.

Labor-force participation among Mexican males in their early retirement years (60 to 64 years of age) has decreased in recent decades, from 94.6 percent in 1960 to 65.2 percent in 2010. Similar trends are evident elsewhere in Latin America, and have occurred in the developed world. Such trends pose challenges to financial sustainability of social security systems as working-age populations decrease and those in retirement increase both because of demographic trends and decisions to take early retirement. In this study, we find that the Mexican social security system provides incentives to retire early. The retirement incentives of the Mexican social security system affect retirement behavior, and may be one of the main contributors to early retirement decisions, particularly for lower-income populations. We simulated the effect of the reform from a Pay-As-You-Go (PAYG) to the new Personal Retirement Accounts (PRA) system and we find that the PRA system also provides incentives to early retirement. Further analysis is needed to assess the financial sustainability of the social security system and financial security in old age for the largest cohorts in Mexico that will begin to retire by 2040.

To evaluate the benefits and harms of discontinuation of oxytocin after the active phase of labor is reached. Electronic databases (ie, MEDLINE, Scopus, ClinicalTrials.gov, EMBASE, ScienceDirect, the Cochrane Library at the CENTRAL Register of Controlled Trials, Scielo) were searched from their inception until April 2017. We included all randomized controlled trials comparing discontinuation (ie, intervention group) and continuation (ie, control group) of oxytocin infusion after the active phase of labor is reached, either after induction or augmentation of labor. Discontinuation of oxytocin infusion was defined as discontinuing oxytocin infusion when the active phase of labor was achieved. Continuation of oxytocin infusion was defined as continuing oxytocin infusion until delivery. Only trials in singleton gestations with vertex presentation at term were included. The primary outcome was the incidence of cesarean delivery. Nine randomized controlled trials, including 1,538 singleton gestations, were identified as relevant and included in the meta-analysis. All nine trials included only women undergoing induction of labor. In the discontinuation group, if arrest of labor occurred, usually defined as no cervical dilation in 2 hours or inadequate uterine contractions for 2 hours or more, oxytocin infusion was restarted. Women in the control group had oxytocin continued until delivery usually at the same dose used at the time the active phase was reached. Women who were randomized to have discontinuation of oxytocin infusion after the active phase of labor was reached had a significantly lower risk of cesarean delivery (9.3% compared with 14.7%; relative risk 0.64, 95% CI 0.48-0.87) and of uterine tachysystole (6.2% compared with 13.1%; relative risk 0.53, 95% CI 0.33-0.84) compared with those who were randomized to have continuation of oxytocin infusion until delivery. Discontinuation of oxytocin infusion was associated with an increase in the duration of the active

Military duty: risk factor for preterm labor? A review.

PubMed

McNeary, A M; Lomenick, T S

2000-08-01

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.

Trends in Labor Force Participation: How Much is Due to Changes in Pensions?

PubMed Central

Rohwedder, Susann

2011-01-01

In the United States, beginning in the late 1980s there was a substantial increase in the labor force participation of men and women in their 60s. Over the same time period the type of pension plans offered by employers shifted strongly from defined benefit plans to defined contribution plans. Defined benefit plans typically have optimal retirement ages embedded in their structure which induce early retirement, whereas defined contribution plans do not favor any particular retirement age. Based on panel data, this paper quantifies the increase in participation due to the change in pension structure. The main result is that the pension changes account for a considerable part of the increase, but other factors also made a contribution. PMID:21857886

2014-09-01

Our aim was to assess the effects of sexual activity during pregnancy on the prognosis of labor. It was a prospective cohort study of labor comparing 72 women declaring unprotected vaginal sexual intercourse after 37 weeks of pregnancy consecutively recruited to 72 women claiming no sexual contact after 37 weeks of pregnancy also consecutively recruited. The sexually active group at term were significantly involved in more frequent heterosexual intercourse after 28 weeks pregnancy and before term (RR = 37.8; CI = 19.8-515.4). Women sexually active were significantly admitted during the active phase of labor (RR = 2.4; IC = 1.6-5.3), with the fetal head at station 0 and more (RR = 1.5; CI = 1.3-5.2). They significantly had a shorter active phase (RR = 1.7; CI = 1.5-3.7) and a shorter second stage (RR = 1.5; CI = 1.2-3.3). They significantly had a normal pattern of labor (RR = 2.1; CI = 1.2-5.3), a higher rate of spontaneous deliveries (RR = 2.1; CI = 1.5-4.5), a lower rate of caesarean sections (RR = 0.46; CI = 0.1-0.8) and needed less oxytocin usage before expulsion (RR = 0.5; CI = 0.2-0.7). Sexual activity during pregnancy improves the prognosis of labor in Cameroonian women. In the absence of contraindications, consented unprotected heterosexual intercourse should be promoted in pregnant women.

Force Dynamics During T Cell Activation

NASA Astrophysics Data System (ADS)

Garcia, David A.; Upadhyaya, Arpita

T cell activation is an essential step in the adaptive immune response. The binding of the T cell receptor (TCR) with antigen triggers signaling cascades and cell spreading. Physical forces exerted on the TCR by the cytoskeleton have been shown to induce signaling events. While cellular forces are known to depend on the mechanical properties of the cytoskeleton, the biophysical mechanisms underlying force induced activation of TCR-antigen interactions unknown. Here, we use traction force microscopy to measure the force dynamics of activated Jurkat T cells. The movements of beads embedded in an elastic gel serve as a non-invasive reporter of cytoskeletal and molecular motor dynamics. We examined the statistical structure of the force profiles throughout the cell during signaling activation. We found two spatially distinct active regimes of force generation characterized by different time scales. Typically, the interior of the cells was found to be more active than the periphery. Inhibition of myosin motor activity altered the correlation time of the bead displacements indicating additional sources of stochastic force generation. Our results indicate a complex interaction between myosin activity and actin polymerization dynamics in producing cellular forces in immune cells.

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

The feminization of foreign currency earnings: women's labor in Sri Lanka.

PubMed

Samarasinghe, V

1998-01-01

This paper considers women's participation in foreign currency earning activities in Sri Lanka. The author first analyzes the structure of women's participation patterns in the major foreign currency earning activities in the country, including consideration of their wage levels and the impact of ethnicity, age, educational levels, and skills upon the different components of those activities in which women participate. She then probes the applicability for Sri Lanka of Guy Standing's argument that structural adjustment policies (SAP) have triggered a change in labor force practices leading to a feminization through flexible labor. Many studies have shown that cutbacks in subsidies mandated by SAPs and initiated in the 1980s among developing countries have adversely affected poor women. Women have adjusted to the new situation in a variety of ways, ranging from cutting their household budgets for basic needs to seeking income-generating work in the informal sector and participating in labor-intensive manufacturing activities. In closing, the author assesses the degree to which the new demands made upon women resulting from the effect of SAPs upon their households have stimulated women's increasing participation in foreign currency earning activities.

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.

The labor force participation rates of men and women aged 62-79 have notably increased since the mid-1990s. The result is a dramatic increase in the share of total money income attributable to earnings. For persons aged 65-69, the earnings share of total income increased from 28 percent in 1980 to 42 percent in 2009. For this age group in the late 1980s and early 1990s, Social Security benefits and earnings were roughly equal shares of total money income (about 30 percent); the earnings share is now more than 12 percentage points larger. When we focus on aged persons who receive Social Security benefits, earnings shares have increased markedly throughout the 62-79 age range since the early 1990s. We show that for aged persons with labor market earnings, those earnings have a large effect on their relative position in the distribution of annual money income of older Americans.

To evaluate the efficacy and safety profile of paracetamol in comparison with tramadol for pain relief during active labor. Prospective, randomized, double-blind study. Maternity Wing of the Postgraduate Institute of Medical Education and Research, Chandigarh. Sixty laboring, primiparous, full-term parturients with uncomplicated, singleton pregnancy in spontaneous labor and cervical dilatation of 3-5 cm. Parturients were randomized into 2 groups to receive either 1 mg/kg of tramadol intramuscularly (group T; n = 29) or 1 g of paracetamol intravenously (group P; n = 30). Same doses of the drugs were repeated after 4 hours of initial dose. Primary outcome of the study was to assess the analgesic efficacy of the 2 drugs as measured by visual analog scale (VAS) score. Secondary outcome recorded was duration of labor, presence of any maternal, or fetal adverse events during the study. Both the groups showed comparable VAS scores at all times of observation. Lower mean VAS scores were reported in both the groups till 120 minutes only. The duration of first stage of labor was shorter in group P (248.00 ± 98.171 vs 340.63 ± 111.592 minutes; P = .003). The duration of second stage of labor was comparable between the 2 groups. Higher incidence of maternal side effects such as nausea/vomiting and sedation was associated with the use of tramadol. Neonatal outcome was comparable. Intravenous paracetamol provides comparable analgesia as intramuscular tramadol during active labor. Copyright © 2014 Elsevier Inc. All rights reserved.

2015-01-01

The objective of the study was to perform serial magnetomyographic examinations in order to detect changes in synchrony characteristics of myometrial electrophysiological activity as women approach labor. Of the total of 56 patients recruited, the results of 149 examinations from 29 patients were included in the analysis. The global synchrony across each sensor spread over the abdomen was computed and quantified as synchronization index. The mean and the median value of the global synchrony were computed and correlated with time to active labor from the last recording. Overall, synchrony increased as the patient approached active labor (P = .035). Furthermore, mean synchronization index increased twice as fast in the nonnulliparous group compared to the nulliparous group (P = .039). The changes in synchrony of uterine electrophysiological activity near term could aid in prediction of labor. PMID:25352329

To detect the expression of the TRPC3 channel protein in the tissues of women experiencing preterm labor and investigate its interaction with T lymphocytes, providing a theoretical basis for the clinical prevention of threatened preterm labor and the development of drug-targeted therapy. Forty-seven women experiencing preterm labor and 47 women experiencing normal full-term labor were included in this study. All included women underwent delivery via cesarean section; uterine samples were obtained at delivery. The expression of TRPC3 in uterine tissue was detected by immunohistochemistry, real-time quantitative reverse transcription-PCR, and western blot assay. Activation of T lymphocytes in peripheral blood and uterine tissue were detected by flow cytometry. A TRPC3-/- mouse model of inflammation-induced preterm labor was established; expression of TRPC3, Cav3.1, and Cav3.2 were analyzed in mouse uterine tissue. Activation of T lymphocytes in female mouse and human peripheral blood samples was determined using flow cytometry. In women experiencing preterm labor, expression of TRPC3 and the Cav3.1 and Cav3.2 proteins was significantly increased; in addition, the percentage of CD3+, CD4+, and CD8+ T cells in peripheral blood was significantly decreased. TRPC3 knockout significantly delayed the occurrence of preterm labor in mice. The muscle tension of ex vivo uterine strips was lower, Cav3.1 and Cav3.2 protein expression was lower, and the percentage of CD8+ T lymphocytes was significantly increased in wild-type mice subjected to an inflammation-induced preterm labor than in wild-type mice experiencing normal full-term labor. TRPC3 is closely related to the initiation of labor. TRPC3 relies on Cav3.1 and Cav3.2 proteins to inhibit inflammation-induced preterm labor by inhibiting the activation of T cells, in particular CD8+ T lymphocytes. © 2018 The Author(s).

Too many people with HIV have left the job market permanently and those with reduced work capacity have been unable to keep their jobs. There is a need to examine the health effects of labor force participation in people with HIV. This study presents longitudinal data from 1,415 HIV-positive men who have sex with men taking part in the Multicenter AIDS Cohort Study. Generalized Estimating Equations show that employment is associated with better physical and mental health quality of life and suggests that there may be an adaptation process to the experience of unemployment. Post-hoc analyses also suggest that people who are more physically vulnerable may undergo steeper health declines due to job loss than those who are generally healthier. However, this may also be the result of a selection effect whereby poor physical health contributes to unemployment. Policies that promote labor force participation may not only increase employment rates but also improve the health of people living with HIV. PMID:22814570

[Induced abortion and labor activity. Reflections for discussion].

PubMed

Orjuela-Ramírez, María E

2012-06-01

The induced abortion is a global phenomenon that according to various authors respond to socially constructed patterns of behavior and where they influence social realities of each country. This phenomenon requires the information necessary to understand the complex process leading to the decision of women to opt for abortion and able to understand the social, economic and health that can explain this requirement. For this purpose is presented for discussion, some considerations on voluntary abortion and labor activity of women who opt for this practice, with special mention of the situation in Spain. The arguments are supported by statistical analysis of the voluntary interruption of pregnancy (IVE) reported by the Ministry of Health and Social Policy, participation of women in the labor market in Spain obtained from the National Statistics Institute (INE), the research results on the association between employment status of women and voluntary termination of pregnancy and comprehensive review of scientific literature on the different perspectives of the approach of voluntary abortion. Analysis deserves special importance of women's work activity as a possible factor in the decision of women to terminate their pregnancies, a variable that has been identified in most of the investigations as a socioeconomic condition for women who choose for that alternative, considering that pregnancy interferes with the employment of women or, rather, prevents them from use.

Labor Dystocia: A Common Approach to Diagnosis.

PubMed

Neal, Jeremy L; Lowe, Nancy K; Schorn, Mavis N; Holley, Sharon L; Ryan, Sharon L; Buxton, Margaret; Wilson-Liverman, Angela M

2015-01-01

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.

Simultaneous Recording and Analysis of Uterine and Abdominal Muscle Electromyographic Activity in Nulliparous Women During Labor.

2017-03-01

To record and characterize electromyography (EMG) from the uterus and abdominal muscles during the nonlabor to first and second stages of labor and to define relationships to contractions. Nulliparous patients without any treatments were used (n = 12 nonlabor stage, 48 during first stage and 33 during second stage). Electromyography of both uterine and abdominal muscles was simultaneously recorded from electrodes placed on patients' abdominal surface using filters to separate uterine and abdominal EMG. Contractions of muscles were also recorded using tocodynamometry. Electromyography was characterized by analysis of various parameters. During the first stage of labor, when abdominal EMG is absent, uterine EMG bursts temporally correspond to contractions. In the second stage, uterine EMG bursts usually occur at same frequency as groups of abdominal bursts and precede abdominal bursts, whereas abdominal EMG bursts correspond to contractions and are accompanied by feelings of "urge to push." Uterine EMG increases progressively from nonlabor to second stage of labor. (1) Uterine EMG activity can be separated from abdominal EMG events by filtering. (2) Uterine EMG gradually evolves from the antepartum stage to the first and second stages of labor. (3) Uterine and abdominal EMG reflect electrical activity of the muscles during labor and are valuable to assess uterine and abdominal muscle events that control labor. (4) During the first stage of labor uterine, EMG is responsible for contractions, and during the second stage, both uterine and abdominal muscle participate in labor.

Labor contractions help instigate behavioral responses at birth (viz., breathing and suckling) that are vital for the newborn's adaptation to the extrauterine world (Ronca et al., 1996). In the present study, we analyzed the role of labor contractions in postpartum oxygenation and behavioral activity of newborn rat pups. Newborns were observed following either vaginal (V) or cesarean delivery. For cesarean delivery, day 21 pregnant dams' were administered a spinal transaction to eliminate lower body sensation, a laparotomy was performed and the uterus was maintained in a heated (37.5 C) bath. Four rat fetuses in one of the dams' paired uterine horn were compressed (C) to Simulate labor contractions (20 sec/min for 10 min) while four fetuses in the opposite horn were not compressed (NC). Fetuses were surgically removed from the uterus, stroked with a soft brush to mimic postnatal licking by the dam, the umbilical cord occluded. Pups were exposed to room temperature (22 C) for one hr, then nest temperature (33 C) for one hr. PO2, CO2, and O2, saturation were determined at 0, 30, 60, or 120 min post delivery using a blood gas analyzer. V and C delivered neonates showed comparable rates of PO2, CO2 and O2 saturation whereas NC neonates showed depressed levels at all time points (p<0.05). Respiratory rates of V, C and NC neonates increased significantly (p<0.05) over the first two postpartum hrs and did not differ across groups. Postpartum behavioral activity was significantly greater in V and C conditions and positively correlated with postnatal oxygenation. These findings provide further evidence for importance of labor contractions in early postpartum adaptation.

Worldwide induction and cesarean delivery rates have increased rapidly, with consequences for subsequent pregnancies. The majority of intrapartum cesarean deliveries are performed for failure to progress, typically in nulliparous women at term. Current uterine registration techniques fail to identify inefficient contractions leading to first-stage labor arrest. An alternative technique, uterine electromyography has been shown to identify inefficient contractions leading to first-stage arrest of labor in nulliparous women with spontaneous onset of labor at term. The objective of this study was to determine whether this finding can be reproduced in induction of labor. Uterine activity was measured in 141 nulliparous women with singleton term pregnancies and a fetus in cephalic position during induced labor. Electrical activity of the myometrium during contractions was characterized by its power density spectrum. No significant differences were found in contraction characteristics between women with induced labor delivering vaginally with or without oxytocin and women with arrested labor with subsequent cesarean delivery. Uterine electromyography shows no correlation with progression of labor in induced labor, which is in contrast to spontaneous labor. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

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.

2014-05-01

We sought to examine the relationship between maternal markers of inflammation and labor performance. A nested cohort study was performed utilizing an established cohort of term nulliparous patients. Maternal blood was collected at the onset of regular, painful contractions in patients undergoing labor induction or at admission in patients with spontaneous labor. Levels of cytokines including interleukin (IL)-1, IL-6, and tumor necrosis factor-α were determined using standard multiplex methodology. Maternal demographic data were collected prospectively. Detailed retrospective chart review was performed to extract data on cervical dilation, effacement, and station during labor. Subjects were excluded if they failed to achieve complete dilation. Mixed effects modeling was used to examine the association between serum cytokine quartiles and labor progress in the latent and active phases. In all, 334 women were included in our analysis. The lowest quartile of IL-6 was associated with slower latent labor (P = .001). In contrast, the highest quartiles of IL-1 and tumor necrosis factor-α were associated with slower active labor (P = .03 and .0002, respectively). Proinflammatory activation is important in labor initiation. However, once active labor is established, excess inflammation can be detrimental to efficient labor progress. These data may explain, in part, the known associations among clinical chorioamnionitis, cesarean delivery, and postpartum hemorrhage. Copyright © 2014 Mosby, Inc. All rights reserved.

2017-03-01

We use register data of 88,948 sick-listed workers in Denmark over the period 2008-2011 to investigate the effect of active labor market programs on the duration until returning to non-subsidized employment and the duration of this employment. To identify causal treatment effects, we exploit over-time variation in the use of active labor market programs in 98 job centers and time-to- event. We find that ordinary education and subsidized job training have significant positive employment effects. Subsidized job training has a large, positive effect on the transition into employment but no effect on the subsequent employment duration. In contrast, ordinary education has a positive effect on employment duration but no effect on the transition into employment. The latter effect is the result of two opposing effects, a large positive effect of having completed education and a large negative lock-in effect, with low re-employment chances during program participation.

We sought to estimate the association between fetal gender and first-stage labor curve at term. Within a large, retrospective cohort study of consecutive, singleton term labor patients who delivered in the second stage, we compared the active phase of first-stage labor by fetal gender. The primary outcome was length of active stage 1. Interval-censored regression was used to estimate the effect of fetal gender on the duration of active first stage (4-10 cm) and was adjusted for relevant covariates. Of 2400 women, 2373 women had complete labor information and were available for this analysis. Male gender was associated with both a statistically significantly longer active first stage of labor (4.6 vs 4.0 hours; P = .002) and stratified analyses by parity and labor type. Male fetuses are associated with longer active phase of the first stage of labor and, specifically, may need to be considered in the setting of arrest diagnoses. Copyright © 2012 Mosby, Inc.

Inequality of pension arrangements among different segments of the labor force in China.

Wu, Ling

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.

2010-01-01

The comparative analysis of the aging process of population in the context of demographic transition was represented in this article. The values of the basic medico-demographic indices of aging population for Russia and developed countries were identified. The results of the United Nations forecasts, probabilistic prognosis of quantity and age-gender structure for the Russian population were analyzed. The state of demographic trouble in Russia was convincingly shown. Special attention was given to the examination of the demographic and professional risks of a reduction in the population at the working ages, to an increase in the demographic load on the labor forces. The need for further studies was proven, dedicated to the use of geroprotectors and contemporary gerontotechnologies as means and methods of the prevention of premature work ability reduction, retarding of the aging processes of the worker's organism, decrease in the level of mortality and increase in the professional longevity.

[Perspectives of work, age, health, and labor market participation in Germany].

PubMed

Hasselhorn, H M; Rauch, A

2013-03-01

The German population is aging and shrinking. This will have a significant impact on the labor market, because labor supply will start to shrink. Consequently, there is a need to develop additional labor market resources. In this setting, a crucial issue is the health and employment of the older working population. This article discusses--on the basis of nine articles in this special issue--the health of the working population in the context of work, age, and labor participation. It shows the diversity of morbidity in the work force in general and particularly in older age, and it identifies older labor force groups with good health and those with bad health. The latter shows that "working while having a bad state of health" is today's reality. Labor market participation is less dependent on health than on the "work ability" and/or the "motivation to work" of older workers. The employment dynamics of an aging population will be a key issue in future political debate. A reliable knowledge base is needed for proper discussion, judgment, and action in the economic, political, and social fields. Current research is often focused on subtopics or on subgroups; however, a network of all the related scientific disciplines and the establishment of new comprehensive research approaches are needed in this area.

Alternative demographic futures and the composition of the demand for labor, by industry and by occupation.

PubMed

Serow, W J

1981-01-01

An effort is made in this discussion to demonstrate the effects of varying rates of population growth upon the industrial and occupational compositions of demand for labor. The discussion extends previous research activity that has demonstrated that changes in the composition of consumer demand are insensitive to alternative rates of population growth. The discussion begins with a replication of projections of consumer demand patterns under 3 alternative population projections and then transforms these results into projections of final demand by industrial sector, demand for labor by industrial sector, and demand for labor by occupational group. Projections of US household composition patterns are made for the 1980-2020 period. The size and composition of the population and households are derived from US Bureau of the Census Series 1, 2, and 3 projections. From these, projections of size and composition of the labor force are derived utilizing Bureau of Labor Statistics' to 1990. Projections of average earnings per worker, in the aggregate, are taken from Bureau of Economic Analysis projections. The results show that both labor force compositions are relatively insensitive to varying demographic patterns. The industrial composition reflects a continuation of already existing trends, but the occupational composition shows some tendency to move away from professional and highly skilled blue collar occupations and towards service and clerical occupations. The results contain a variety of implications for policy considerations concerning higher education and the proper functioning of the labor market. The relative decline in the number of professional and managerial workers, the groups who are most likely to possess a university degree, suggests that the prospects for conventional higher education might be even less bright than would be suggested by an inspection of trends in the size of the 18-24 year old population. Some mitigation of this possibly adverse trend is

The challenge of an aging work force: keeping older workers employed and employable.

PubMed

Rix, S E

1996-01-01

This article reviews labor-force trends and older-worker employment policies in Japan and the United States. Both countries have aging work forces, but Japan's labor force is and for some time has been older than that of the United States. Japan's Ministry of Labor began addressing older-worker issues over 30 years ago and in the ensuing years has promulgated numerous initiatives to extend working life. Mandatory retirement, however, remains both legal and common in Japan, yet labor-force participation rates are higher for older persons in that country than in the United States, where mandatory retirement is illegal. Japan's older-worker programs and policies clearly seem to have an impact on labor-force rates, although those rates are dropping among the elderly in Japan as well as in the United States. The transferability of these programs and policies to the United States is discussed.

An Empirical Analysis on Labor Unions and Occupational Safety and Health Committees' Activity, and Their Relation to the Changes in Occupational Injury and Illness Rate

Cho, Hm Hak; Kim, Jiyun

2011-01-01

Objectives To find out from an analysis of empirical data the levels of influence, which a labor union (LU) and Occupational Safety and Health Committee (OSHC) have in reducing the occupational injury and illness rate (OIIR) through their accident prevention activities in manufacturing industries with five or more employees. Methods The empirical data used in this study are the Occupational Safety and Health Tendency survey data, Occupational Accident Compensation data and labor productivity and sales data for the years 2003 to 2007. By matching these three sources of data, a final data set (n = 280) was developed and analyzed using SPSS version 18 (SPSS Inc., Chicago, IL, USA). Results It was found that a workplace with a LU has a lower OIIR than one without a LU. In manufacturing industries with five or more employees in 2007, the OIIR of the workplaces without a LU was 0.87%, while that of workplaces with a LU was much lower at 0.45%. In addition, workplaces with an established OSHC had a lower OIIR than those without an OSHC. Conclusion It was found that the OIIR of workplaces with a LU is lower than those without a LU. Moreover, those with the OSHC usually had a lower OIIR than those without. The workplace OIIR may have an impact on management performance because the rate is negatively correlated with labor productivity and sales. In the long run, the OIIR of workplaces will be reduced when workers and employers join forces and recognize that the safety and health activities of the workplace are necessary, not only for securing the health rights of the workers, but also for raising labor productivity.

Maternal Endogenous Forces and Shoulder Dystocia.

PubMed

Grimm, Michele J

2016-12-01

Childbirth is a complicated biomechanical process that many take for granted. However, the delivery forces generated by a mother (uterine contractions and maternal pushing) are strong and have a significant effect on the body and tissues of the fetus, especially during the second stage of labor. Although most infants are born without negative, force-related outcomes, in some infants the normal forces of labor cause an injury that can have either temporary or permanent sequelae. The biomechanical situation is further complicated when an infant's shoulder impacts the maternal pelvis, which provides increased resistance and creates added stresses within the neonatal body and tissues.

Dianatal® is a bioadhesive gliding film which reduces the opposing force to vaginal childbirth. We aimed to investigate the safety, applicability, and impact of Dianatal® obstetric gel on second stage of labor and perineal integrity. Low-risk singleton pregnancies at term were prospectively enrolled. Eligible women were randomly assigned to either labor management without using obstetric gel, or labor management using intermittent application of obstetric gel into the birth canal during vaginal examinations, starting at active phase of labor (≥4 cm dilation). The primary measured outcome was the length of second stage of labor. Overall, 200 cases were analyzed. Demographic, obstetrical, and labor characteristics were similar between the groups. Neither adverse events nor maternal or neonatal side effects were observed. The mean lengths of the active and second stages of labor were comparable between the obstetric gel-treated and the control groups (157 versus 219 min and 48 versus 56 min, respectively). None of the women had grade III/IV perineal tears. Maternal and neonatal outcomes were not negatively influenced by using obstetric gel. No difference was found after sub-group analysis for spontaneous vaginal delivery. Dianatal® obstetric gel is safe in terms of maternal or neonatal use. Albeit a trend toward shorter labor stages using Dianatal® obstetric gel, no significant differences were noted among the groups. In order to further investigate the influence of the obstetric gel on labor stage interval, perineal integrity and maternal and neonatal outcomes, larger randomized clinical trials are needed to be carried out.

DESIGN AND PURPOSE: The purpose of this study is to investigate the effects of music-therapy on labor pain and progress in parturient primipara. Music-therapy during labor increases tolerance to pain; decreasing anxiety, it increases paturition and uterus activity and shorten labor duration. The subjects of this research were 30 women, selected voluntarily and they have been put in two experimental and control group. This research has been conducted in the form of pre-test and post-test design. The experimental group listened to a relaxing music for 30 minutes in each hour for a two-hour period a nd the control group was not exposed to music during this period. For the purpose of gathering data in both groups, the pain scales (verbal, numeric and visual) was used to measure pain. The independent variable in this research is relaxing music and the dependent variables are the pain level and delivery progress. The independent t for sensations of pain in the experimental and control group before intervention has been (p = 0.875) 0.601 in numeric and visual pain and (p < 0.01) 2.92 in verbal pain, and one hour after intervention, it has been (p < 0.0001) 8.527 in visual and numeric pain and (p < 0.0001) 11.824 in verbal pain. Also, the equal value of independent t for the duration of delivery in control group before and after intervention shows that music has not had any effect on the rate of serotonin. The results of statistical analysis show the effect of music on the decrease of sensation of pain in the experimental group as compared with the control group.

Objective Tocodynamometry (Toco—strain gauge technology) provides contraction frequency and approximate duration of labor contractions, but suffers frequent signal dropout necessitating re-positioning by a nurse, and may fail in obese patients. The alternative invasive intrauterine pressure catheter (IUPC) is more reliable and adds contraction pressure information, but requires ruptured membranes and introduces small risks of infection and abruption. Electrohysterography (EHG) reports the electrical activity of the uterus through electrodes placed on the maternal abdomen. This study compared all three methods of contraction detection simultaneously in laboring women. Study Design Upon consent, laboring women were monitored simultaneously with Toco, EHG, and IUPC. Contraction curves were generated in real-time for the EHG and all three curves were stored electronically. A contraction detection algorithm was used to compare frequency and timing between methods. Seventy-three subjects were enrolled in the study; 14 were excluded due to hardware failure of one or more of the devices (12) or inadequate data collection duration(2). Results In comparison with the gold-standard IUPC, EHG performed significantly better than Toco with regard to Contractions Consistency Index (CCI). The mean CCI for EHG was 0.88 ± 0.17 compared to 0.69 ± 0.27 for Toco (p<.0001). In contrast to Toco, EHG was not significantly affected by obesity. Conclusion Toco does not correlate well with the gold-standard IUPC and fails more frequently in obese patients. EHG provides a reliable non-invasive alternative regardless of body habitus.

In this study, I investigate how the impact of the National Health Insurance (NHI) introduction in Taiwan in 1995 on the labor force participation (LFP) decisions of married women varies with income and family structures. Employing the difference-in-differences (DID) approach, I find that the NHI introduction reduced LFP of married women in the twenty-fifth to fiftieth percentiles of the income distribution between 17.8 and 21.7 percentage points (33%-40%). The difference-in-differences-in-differences (DIDID) results suggest that married women in different family structures (the presence of children under 3 or less healthy elderly household members) did not respond differently to the NHI introduction.

Objective To evaluate the labor curves of patients undergoing preterm induction of labor (IOL) and assess possible predictors of vaginal delivery (VD). Study Design Data from the NICHD Consortium on Safe Labor were analyzed. A total of 6,555 women undergoing medically-indicated IOL before 37 weeks gestational age (GA) were included in this analysis. Patients were divided into four groups based on gestational age: A: 24-27+6, B: 28-30+6, C: 31-33+6, and D: 34-36+6 weeks. Pregnant women with a contraindication to VD, IOL at or after 37 weeks and those without data from cervical exam on admission were excluded. ANOVA was used to assess differences between GA groups. Multiple logistic regression was used to assess predictors of VD. A repeated measures analysis was used to determine average labor curves. Results Rates of vaginal live births increased with GA, from 35% (Group A) to 76% (Group D). Parous women [odds ratio (OR)=6.78, 95% confidence interval (CI) 6.38-7.21] and those with a favorable cervix at the start of IOL (OR=2.35, 95% CI 2.23-2.48) were more likely to deliver vaginally. Analysis of labor curves in nulliparous women showed shorter duration of labor with increasing GA; the active phase of labor was, however, similar across all GA. Conclusion The majority of women undergoing medically-indicated preterm IOL between 24 and 36+6 weeks’ GA deliver vaginally. The strongest predictor of VD was parity. Preterm IOL had a limited influence on estimated labor curves across gestational age. PMID:25068566

The basic instrument for the study of China's population and employment: the labor life table.

PubMed

Jiang, Z

1991-01-01

The data and methods are provided for generating a labor life table for China in 1988. The purpose is to supply a useful instrument for studying, planning, and analyzing employment and social services, welfare programs, and insurance. These tables were constructed using age- and sex-specific employment data from the 1% sample of demographic data for 1987 in 13 nonfarming sectors. Employment was derived from the 1985 Industrial Survey on 2 sectors of the nonfarming population. Urban employment and rural agricultural employment were not calculated because of the imprecision of the data. The age structure has unique characteristic differences between the employment rate curves of the material and nonmaterial production sectors. The peak for the nonmaterial production sector is near 50 years for men and 44 years for women, while the curve for the material sector is more nearly bell-shaped with a peak for females at 20-30 years. The female employment pattern indicates that women continue working after the birth of a child, and women do not return to the work force once they resign. The reasons for the pattern in nonmaterial production are indicated. The method used to calculate the labor life table employs the same methods as the multiple life table approach for mortality, with some modifications. The assumption is a static labor population between the ages of 15-70 years. The age for which employment is the highest is selected; then the number of people employed is generated. Employment beyond the peak age is derived through the % of the labor force in the total population. The arithmetic mean value of the labor force for adjacent age groups is determined by survivors until a particular age. Mean work expectancy years and age-specific cumulative labor force are calculated per the life table method. As data become available, causes of death of the labor force and transfer of labor between sectors and regions may be computed. An example of retirement information is that

Active management of third stage of labor played a great role to prevent child birth related hemorrhage. However, maternal morbidity and mortality related to hemorrhage is high due to lack of knowledge and skill of obstetric care providers 'on active management of third stage of labor. Our study was aimed to assess knowledge, practice and associated factors of obstetric care providers (Midwives, Nurses and Health officers) on active management of third stage of labor in Sidama Zone, South Ethiopia. An institution based cross sectional study design was conducted from December 1-30 /2015 among midwives, nurses and health officers. Simple random sampling technique was used to get the total of 528 participants. Data entry was done using EPI Info 3.5.1 and exported to SPSS version 20.0 software package for analysis. The presence of association between independent and dependent variables was assessed using odds ratio with 97% confidence interval by applying logistic regression model. Of the 528 obstetric care providers 37.7% and 32.8% were knowledgeable and skilled to manage third stage of labor respectively. After controlling for possible confounding factors, the result showed that pre/in service training, being midwife and graduation year were found to be the major predictors of proper active management of third stage of labor. The knowledge and practice of obstetric care providers towards active management of third stage of labor can be improved with appropriate interventions like in-service trainings. This study also clearly showed that the level of knowledge and practice of obstetric care providers to wards active management of third stage of labor needs immediate attention of Universities and health science colleges better to revise their obstetrics course contents, health institutions and zonal health bureau should arrange trainings for their obstetrics care providers to enhance skill.

Hirshberg, Adi; Levine, Lisa D; Srinivas, Sindhu

2014-11-01

Maternal weight is thought to impact labor. With rising rates of obesity and inductions, we sought to evaluate labor times among induced women by body mass index (BMI) category. Retrospective cohort study of term inductions from 2005 to 2010. BMI categories were: normal weight (NW), overweight (OW), and obese (Ob) (18.5-24.9, 25-29.9, ≥30 kg/m(2)). Kruskal-Wallis tests compared median latent labor (LL) length and active labor (AL) length. Chi-square determined associations. Multivariable logistic regression controlled for confounders. Analyses were stratified by parity. A total of 448 inductions were analyzed. For nulliparas, there was no difference in LL by BMI category (p = 0.22). However, OW nulliparas had a longer AL compared to NW and Ob nulliparas (3.2, 1.7, 2.0 h, p = 0.005). For multiparas, NW had the shortest LL (5.5 h, p = 0.025) with no difference in AL among BMI categories (p = 0.42). The overall cesarean rate was 23% with no difference by BMI category (p = 0.95). However, Ob women had a greater percentage of first stage cesareans (41%) and NW had a greater percentage of second stage cesareans (55%), p = 0.06. The association between BMI and labor length among inductions differs by phase of labor and parity. BMI also influences the stage of labor in which a cesarean occurs.

Higher-order force moments of active particles

NASA Astrophysics Data System (ADS)

Nasouri, Babak; Elfring, Gwynn J.

2018-04-01

Active particles moving through fluids generate disturbance flows due to their activity. For simplicity, the induced flow field is often modeled by the leading terms in a far-field approximation of the Stokes equations, whose coefficients are the force, torque, and stresslet (zeroth- and first-order force moments) of the active particle. This level of approximation is quite useful, but may also fail to predict more complex behaviors that are observed experimentally. In this study, to provide a better approximation, we evaluate the contribution of the second-order force moments to the flow field and, by reciprocal theorem, present explicit formulas for the stresslet dipole, rotlet dipole, and potential dipole for an arbitrarily shaped active particle. As examples of this method, we derive modified Faxén laws for active spherical particles and resolve higher-order moments for active rod-like particles.

Micropipette force probe to quantify single-cell force generation: application to T-cell activation

In response to engagement of surface molecules, cells generate active forces that regulate many cellular processes. Developing tools that permit gathering mechanical and morphological information on these forces is of the utmost importance. Here we describe a new technique, the micropipette force probe, that uses a micropipette as a flexible cantilever that can aspirate at its tip a bead that is coated with molecules of interest and is brought in contact with the cell. This technique simultaneously allows tracking the resulting changes in cell morphology and mechanics as well as measuring the forces generated by the cell. To illustrate the power of this technique, we applied it to the study of human primary T lymphocytes (T-cells). It allowed the fine monitoring of pushing and pulling forces generated by T-cells in response to various activating antibodies and bending stiffness of the micropipette. We further dissected the sequence of mechanical and morphological events occurring during T-cell activation to model force generation and to reveal heterogeneity in the cell population studied. We also report the first measurement of the changes in Young’s modulus of T-cells during their activation, showing that T-cells stiffen within the first minutes of the activation process.

It is well known that extracellular purines have an important role in pain signaling in the central nervous system. This study analyzes the relationship between extracellular purines and pain perception during active labor. A prospective observational study was performed. Cerebrospinal fluid (CSF) levels of the purines and their metabolites were compared between women at term pregnancy with labor pain (n = 49) and without labor pain (Caesarian section; n = 47). Control groups (healthy men and women without chronic or acute pain-n = 40 and 32, respectively) were also investigated. The CSF levels of adenosine were significantly lower in the labor pain group (P = 0.026) and negatively correlated with pain intensity measured by a visual analogue scale (r = -0.48, P = 0.0005). Interestingly, CSF levels of uric acid were significantly higher in healthy men as compared to women. Additionally, pregnant women showed increased CSF levels of ADP, GDP, adenosine and guanosine and reduced CSF levels of AMP, GTP, and uric acid as compared to non-pregnant women (P < 0.05). These findings suggest that purines, in special the nucleoside adenosine, are associated with pregnancy and labor pain.

Tocodynamometry (Toco; strain gauge technology) provides contraction frequency and approximate duration of labor contractions but suffers frequent signal dropout, necessitating repositioning by a nurse, and may fail in obese patients. The alternative invasive intrauterine pressure catheter (IUPC) is more reliable and adds contraction pressure information but requires ruptured membranes and introduces small risks of infection and abruption. Electrohysterography (EHG) reports the electrical activity of the uterus through electrodes placed on the maternal abdomen. This study compared all 3 methods of contraction detection simultaneously in laboring women. Upon consent, laboring women were monitored simultaneously with Toco, EHG, and IUPC. Contraction curves were generated in real-time for the EHG, and all 3 curves were stored electronically. A contraction detection algorithm was used to compare frequency and timing between methods. Seventy-three subjects were enrolled in the study; 14 were excluded due to hardware failure of 1 or more of the devices (n = 12) or inadequate data collection duration (n = 2). In comparison with the gold-standard IUPC, EHG performed significantly better than Toco with regard to the Contractions Consistency Index (CCI). The mean CCI for EHG was 0.88 ± 0.17 compared with 0.69 ± 0.27 for Toco (P < .0001). In contrast to Toco, EHG was not significantly affected by obesity. Toco does not correlate well with the gold-standard IUPC and fails more frequently in obese patients. EHG provides a reliable noninvasive alternative, regardless of body habitus.

Major depressive disorder (MDD) has been found to be negatively associated with labor market outcomes. However, MDD has many different courses that are chronic or persistent, relapsing and remitting, or limited to a single lifetime episode. Such heterogeneity has been ignored in most past analyses. We examine the impact of heterogeneity in course of MDD on labor market outcomes. Wave I (2001-2002) respondents of the National Epidemiological Survey on Alcohol and Related Conditions - a nationally representative panel survey - were interviewed on average 3 years later (2004-2005). We categorized changes in MDD before and after wave I and before wave II into six courses: incident, recent remission, persistent remission, relapse, persistent depression, and no history of MDD. Odds ratios (ORs) and marginal effects of MDD transitions in multivariable multinomial regressions of labor market outcomes (being out of the labor force, being unemployed, working part-time, and working full-time -- the reference outcome) are reported. Men and women who exhibited persistent remission (2 to 3 years) were equally likely to be in the labor force, employed, and working full-time, compared to those with no history of MDD (reference group). For men, recently remitted MDD (less than 1 year), compared to the reference group, increased the likelihood of being unemployed (3.2% higher probability of being unemployed conditional on being in the labor force; OR = 1.97, 95% confidence interval [CI] = 1.13--3.44) and working part-time (5.8% higher probability of working part-time conditional on being employed; OR = 1.75, 95% CI = 1.10-2.80). For women, no statistically significant effect for recent remission was found. The negative effects of incident onset, relapse, and persistence of MDD were found on some labor market outcomes for men and, to a lesser extent, for women. Clinical treatment for depression should be coordinated and/or integrated with work-related interventions that help

There is limited understanding of the type and extent of maternal postures that midwives should encourage or support during labor. The aims of this study were to identify a set of postures and movements commonly seen during labor, to develop an activity monitoring system for use during labor, and to validate this system design. Volunteer student midwives simulated maternal activity during labor in a laboratory setting. Participants (N = 15) wore monitors adhered to the left thigh and left shank, and adopted 13 common postures of laboring women for 3 minutes each. Simulated activities were recorded using a video camera. Postures and movements were coded from the video, and statistical analysis conducted of agreement between coded video data and outputs of the activity monitoring system. Excellent agreement between the 2 raters of the video recordings was found (Cohen's κ = 0.95). Both sensitivity and specificity of the activity monitoring system were greater than 80% for standing, lying, kneeling, and sitting (legs dangling). This validated system can be used to measure elected activity of laboring women and report on effects of postures on length of first stage, pain experience, birth satisfaction, and neonatal condition. This validated maternal posture-monitoring system is available as a reference-and for use by researchers who wish to develop research in this area. © 2015 by the American College of Nurse-Midwives.

The activity of matrix degrading enzymes plays a leading role in the rupture of the fetal membranes under normal and pathological human labor, and matrix metalloproteinase-9 (MMP-9) it is considered a biomarker of this event. To gain further insight into local MMP-9 origin and activation, in this study we analyzed the contribution of human placental leukocytes to MMP-9 secretion and explored the local mechanisms of the pro-enzyme activation. Placental blood leukocytes were obtained from women at term gestation without labor and maintained in culture up to 72 h. MMP-9 activity in the culture supernatants was determined by zymography and using a specific substrate. The presence of a potential pro-MMP-9 activator in the culture supernatants was monitored using a recombinant biotin-labeled human pro-MMP-9. To characterize the endogenous pro-MMP-9 activator, MMP-1, -3, -7 and -9 were measured by multiplex assay in the supernatants, and an inhibition assay of MMP-9 activation was performed using an anti-human MMP-3 and a specific MMP-3 inhibitor. Finally, production of MMP-9 and MMP-3 in placental leukocytes obtained from term pregnancies with and without labor was assessed by immunofluorescence. Placental leukocytes spontaneously secreted pro-MMP-9 after 24 h of culture, increasing significantly at 48 h (P≤0.05), when the active form of MMP-9 was detected. Culture supernatants activated the recombinant pro-MMP-9 showing that placental leukocytes secrete the activator. A significant increase in MMP-3 secretion by placental leukocytes was observed since 48 h in culture (P≤0.05) and up to 72 h (P≤0.001), when concentration reached its maximum value. Specific activity of MMP-9 decreased significantly (P≤0.005) when an anti-MMP-3 antibody or a specific MMP-3 inhibitor were added to the culture media. Placental leukocytes from term labor produced more MMP-9 and MMP-3 compared to term non-labor cells. In this work we confirm that placental leukocytes from human term

Compensating differentials, labor market segmentation, and wage inequality.

PubMed

Daw, Jonathan; Hardie, Jessica Halliday

2012-09-01

Two literatures on work and the labor market draw attention to the importance of non-pecuniary job amenities. Social psychological perspectives on work suggest that workers have preferences for a range of job amenities (e.g. Halaby, 2003). The compensating differentials hypothesis predicts that workers navigate tradeoffs among different job amenities such that wage inequality overstates inequality in utility (Smith, 1979). This paper joins these perspectives by constructing a new measure of labor market success that evaluates the degree to which workers' job amenity preferences and outcomes match. This measure of subjective success is used to predict workers' job satisfaction and to test the hypothesis that some degree of labor force inequality in wages is due to preference-based tradeoffs among all job amenities. Findings demonstrate that the new measure predicts workers' job satisfaction and provides evidence for the presence of compensating differentials in the primary and intermediate, but not secondary, labor markets.

Measuring the effect of husband's health on wife's labor supply.

PubMed

Siegel, Michele J

2006-06-01

A sizable proportion of women remain married well into late life and an increasing proportion of them participate in the labor force. Since women tend to marry men older than themselves and men tend to experience serious illnesses at younger ages than women, women frequently witness declining health in their husbands. This is likely to affect a wife's labor-leisure trade-off in offsetting ways. Prior studies have not sought to disentangle the effect of a husband's poor health on his wife's reservation wage from the income effect of his ill health. We argue that, if we control for husband's earnings, the coefficient of husband's health in models of his wife's labor force participation (and hours of work) will reflect, in part, her preference over whether to decrease her labor supply to provide health care for her husband or whether to instead increase it to purchase this care in the market. However, husband's earnings are likely to be endogenous in these models due to unobserved characteristics common to husbands and wives. We find that the estimated effect of husband's health depends on whether we instrument for husband's earnings and on the health measure used. This is indicative of the importance of using a variety of health measures and controlling for husband's earnings, and their endogeneity, in future research on the effect of husband's health on wife's labor supply.

Flippen, Chenoa

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.

The labor of a lifetime?: health and occupation type as predictors of workforce exit among older Australians.

PubMed

McPhedran, Samara

2012-03-01

The structural aging of the population and withdrawal of older people from the labor force have become common themes within Western social policy discourse and have particular relevance to policy development around health and aging. The current study examines whether particular occupation types are associated with both poor health and an increased likelihood of labor force exit. Longitudinal data are used to examine workforce participation among older Australians (aged between 55 and 64, in 2002). Older workers in trades, labor, and production occupations, the majority of whom are men, have poorer general health than their counterparts in other occupations and are also the most likely to exit the workforce. These findings suggest that a number of older men in Australia (and, indeed, elsewhere) may face both poor health and limited employment opportunities in areas that match their abilities and experience. These individuals may experience a number of years out of the labor force, highlighting a role for targeted policies and programs.

PROBLEM Activated/effector T cells seem to play a role in the pathological inflammation associated with preterm labor. The aim of this study was to determine whether in vivo T-cell activation by a monoclonal αCD3ε antibody induces preterm labor and birth. METHOD OF STUDY Pregnant B6 mice were intraperitoneally injected with a monoclonal αCD3ε antibody or its isotype control. The gestational age and the rates of preterm birth and pup mortality at birth, as well as the fetal heart rate and umbilical artery pulsatility index, were determined. RESULTS Injection of a monoclonal αCD3ε antibody led to preterm labor/birth [αCD3ε 83 ± 16.97% (10/12) vs. isotype 0% (0/8)], and increased the rate of pup mortality at birth [αCD3ε 87.30 ± 8.95% (77/85) vs. isotype 4.91 ± 4.34% (3/59)]. In addition, injection of a monoclonal αCD3ε antibody decreased the fetal heart rate and increased the umbilical artery pulsatility index when compared to isotype controls. CONCLUSION In vivo T-cell activation by a monoclonal αCD3ε antibody in late gestation induces preterm labor and birth. PMID:27658719

The purpose of this study was to evaluate the labor curves of patients who undergo preterm induction of labor (IOL) and to assess possible predictors of vaginal delivery (VD). Data from the National Institute of Child Health and Human Development Consortium on Safe Labor were analyzed. A total of 6555 women who underwent medically indicated IOL at <37 weeks of gestation were included in this analysis. Patients were divided into 4 groups based on gestational age (GA): group A, 24-27+6 weeks; B, 28-30+6 weeks; C, 31-33+6 weeks; and D, 34-36+6 weeks. Pregnant women with a contraindication to VD, IOL ≥37 weeks of gestation, and without data from cervical examination on admission were excluded. Analysis of variance was used to assess differences between GA groups. Multiple logistic regression was used to assess predictors of VD. A repeated measures analysis was used to determine average labor curves. Rates of vaginal live births increased with GA, from 35% (group A) to 76% (group D). Parous women (odds ratio, 6.78; 95% confidence interval, 6.38-7.21) and those with a favorable cervix at the start of IOL (odds ratio, 2.35; 95% confidence interval, 2.23-2.48) were more likely to deliver vaginally. Analysis of labor curves in nulliparous women showed shorter duration of labor with increasing GA; the active phase of labor was, however, similar across all GAs. Most women who undergo medically indicated preterm IOL between 24 and 36+6 weeks of gestation deliver vaginally. The strongest predictor of VD was parity. Preterm IOL had a limited influence on estimated labor curves across GAs. Copyright © 2015 Elsevier Inc. All rights reserved.

The Detour of an Obstetric Technology: Active Management of Labor Across Cultures.

PubMed

Maffi, Irene

2016-01-01

Active management of labor (AML) is an obstetric technology developed in Ireland in the 1970s to accelerate labor in nulliparous women. This technology achieved rapid success in Great Britain and in English-speaking countries outside America, which adopted it before many other states around the world. In this article, I explore AML's technical and social characteristics when it was first designed, and then examine its local inflections in a Jordanian and a Swiss maternity hospital to shed light on the ways its transnational circulation modifies its script. I argue that its application is shaped by local material constraints and specific sociocultural configurations, gender regimes, and hospital cultures. Finally, I make a comparative analysis of AML practices in these two settings and in the foundational textbook to disentangle the technical and sociocultural components modeling its local applications.

To examine whether falls are associated with the subsequent ability to work among workers 65 years and older. This longitudinal cohort study followed older workers enrolled in the Health and Retirement Study. Outcomes included time to health-related work limitation and to labor force exit. After adjustment multiple falls with or without a medically-treated injury were associated with time to limitation (HR = 1.77, 95% CI: 1.30-2.40; HR = 1.48, 95% CI: 1.26-1.73, respectively). Adjustment mitigated a crude relationship between falls and time to exit. Significant interactions suggest the relationship between falls and labor force exit depends on age, race and job demands. Falls, both non-injurious and injurious, are associated with subsequent health-related work limitation among workers 65 and older. Fall prevention activities would benefit workers who want or need to keep working past age 65.

Abstract Background Skilled labor force is very important in economic growth. Workers become skilled when they are healthy and able to be educated and work. In this study, we estimated the effects of health indicators on labor supply. We used labor force participation rate as the indicator of labor supply. We categorized this indicator into 2 indicators of female and male labor force participation rates and compared the results of each estimate with the other. Methods This study was done in eastern Mediterranean countries between 1995 and 2011. We used a panel cointegration approach for estimating the models. We used Pesaran cross sectional dependency, Pesaran unit root test, and Westerlund panel cointegration for this issue. At the end, after confirmation of having random effect models, we estimated them with random effects. Results Increasing the fertility rate decreased the female labor supply, but increased the male labor supply. However, public health expenditures increased the female labor supply, but decreased the male labor supply because of substitution effects. Similar results were found regarding urbanization. Gross domestic product had a positive relationship with female labor supply, but not with male labor supply. Besides, out of pocket health expenditures had a negative relationship with male labor supply, but no significant relationships with female labor supply. Conclusion The effects of the health variables were more severe in the female labor supply model compared to the male model. Countries must pay attention to women’s health more and more to change the labor supply. PMID:26060746

Stark, Mary Ann

: Therapeutic showering is a holistic nursing intervention that is often available and supports physiologic labor. The purpose of this study was to compare the effectiveness of therapeutic showering with usual care during active labor. Research questions were as follows: Are there significant differences between women who showered 30 minutes during active labor and those who received usual labor care in anxiety, tension, relaxation, pain, discomfort, and coping? Is there a difference in use of obstetric interventions between groups? A convenience sample of healthy low-risk women in active labor was recruited (N = 32). A pretest posttest control group repeated-measures design was used. Participants were randomized to treatment group (n = 17), who showered for 30 minutes, or to control group (n = 14) who received usual labor care. Women evaluated pain, discomfort, anxiety, tension, coping, and relaxation at enrollment, again 15 minutes after entering the shower or receiving usual care, then again 30 minutes after entering the shower or receiving usual care. Chart reviews after delivery recorded obstetric interventions. The showering group had statistically significant decreases in pain, discomfort, anxiety and tension, and significant increase in relaxation. There were no differences in use of obstetric interventions. Therapeutic showering was effective in reducing pain, discomfort, anxiety, and tension while improving relaxation and supporting labor in this sample.

Immune cells in term and preterm labor

Labor resembles an inflammatory response that includes secretion of cytokines/chemokines by resident and infiltrating immune cells into reproductive tissues and the maternal/fetal interface. Untimely activation of these inflammatory pathways leads to preterm labor, which can result in preterm birth. Preterm birth is a major determinant of neonatal mortality and morbidity; therefore, the elucidation of the process of labor at a cellular and molecular level is essential for understanding the pathophysiology of preterm labor. Here, we summarize the role of innate and adaptive immune cells in the physiological or pathological activation of labor. We review published literature regarding the role of innate and adaptive immune cells in the cervix, myometrium, fetal membranes, decidua and the fetus in late pregnancy and labor at term and preterm. Accumulating evidence suggests that innate immune cells (neutrophils, macrophages and mast cells) mediate the process of labor by releasing pro-inflammatory factors such as cytokines, chemokines and matrix metalloproteinases. Adaptive immune cells (T-cell subsets and B cells) participate in the maintenance of fetomaternal tolerance during pregnancy, and an alteration in their function or abundance may lead to labor at term or preterm. Also, immune cells that bridge the innate and adaptive immune systems (natural killer T (NKT) cells and dendritic cells (DCs)) seem to participate in the pathophysiology of preterm labor. In conclusion, a balance between innate and adaptive immune cells is required in order to sustain pregnancy; an alteration of this balance will lead to labor at term or preterm. PMID:24954221

Disability Benefit Generosity and Labor Force Withdrawal*

PubMed Central

Mullen, Kathleen J.; Staubli, Stefan

2016-01-01

A key component for estimating the optimal size and structure of disability insurance (DI) programs is the elasticity of DI claiming with respect to benefit generosity. Yet, in many countries, including the United States, all workers face identical benefit schedules, which are a function of one’s labor market history, making it difficult to separate the effect of the benefit level from the effect of unobserved preferences for work on individuals’ claiming decisions. To circumvent this problem, we exploit exogenous variation in DI benefits in Austria arising from several reforms to its DI and old age pension system in the 1990s and 2000s. We use comprehensive administrative social security records data on the universe of Austrian workers to compute benefit levels under six different regimes, allowing us to identify and precisely estimate the elasticity of DI claiming with respect to benefit generosity. We find that, over this time period, a one percent increase in potential DI benefits was associated with a 1.2 percent increase in DI claiming. PMID:28216797

Trends in the growth of population and labour force in Pakistan.

Hashmi, S S

1990-01-01

Trends in the growth of the population and labor force in Pakistan are examined and future prospects for growth of population and labor, particularly agriculture, are estimated. The definition of labor force as employed or seeking work after a short period of employment has led to a great disparity in results for women in the labor force. Past trends in population growth reflected a growth rate of 1.6% for the 1950's, and 2.4% in 1960. The population rose to 84.3 million in 1981 from 42.6 million in 1961, which intercensally was an increase of 3.6% per annum for 1961-72 and 3.1% per annum for 1972-81. The estimated rate for 1981-86 was 2.9%/year. The rural population doubled and the urban tripled. There was a net migration of 2.123 million to urban areas reported in the 1981 census. There is also evidence of a high sex ratio. Balochistan (7.1%) and Sindh (3.6%) provinces have the highest growth rates. Although the largest population is in the Punjab, the growth is the lowest at 2.7%. The population is primarily young -- 44.5% 15 years in 1981, which is the highest in the world. Under high, medium, and low levels of fertility, prospective trends are estimated for 2006 and 2031, and by sex every 5 years from 1981. Population under high fertility is expected to reach 270 million by 2031, which is 3.39 persons/hectare. The population/hectare of land under cultivation was 4.25 in 1981 and is expected to rise to 13.49 persons/hectare in 2031. 11 million acres could be brought under cultivation to reduce the ratio. However, there are ecological considerations as well as an employment problem. The dependency ratio under the high variant will decline from 76.8 persons 0-14 and 65 years/100 persons 15-64 years in 1986 to 70.3 in 2006 which is still considerably higher than other developing countries. It is suggested that replacement level fertility be attained as soon as possible. Under low fertility, replacement level can be reached by 2011 with strong political commitment

2017-11-07

In response to engagement of surface molecules, cells generate active forces that regulate many cellular processes. Developing tools that permit gathering mechanical and morphological information on these forces is of the utmost importance. Here we describe a new technique, the micropipette force probe, that uses a micropipette as a flexible cantilever that can aspirate at its tip a bead that is coated with molecules of interest and is brought in contact with the cell. This technique simultaneously allows tracking the resulting changes in cell morphology and mechanics as well as measuring the forces generated by the cell. To illustrate the power of this technique, we applied it to the study of human primary T lymphocytes (T-cells). It allowed the fine monitoring of pushing and pulling forces generated by T-cells in response to various activating antibodies and bending stiffness of the micropipette. We further dissected the sequence of mechanical and morphological events occurring during T-cell activation to model force generation and to reveal heterogeneity in the cell population studied. We also report the first measurement of the changes in Young's modulus of T-cells during their activation, showing that T-cells stiffen within the first minutes of the activation process. © 2017 Sawicka et al.

Introduction Labor induces a myriad of changes in placental gene expression. These changes may represent a physiological adaptation inhibiting placental cellular processes associated with a high demand for oxygen and energy (e.g., protein synthesis and active transport) thereby promoting oxygen and glucose transfer to the fetus. We hypothesized that mechanistic target of rapamycin complex 1 (mTORC1) signaling, a positive regulator of trophoblast protein synthesis and amino acid transport, is inhibited by labor. Methods Placental tissue was collected from healthy, term pregnancies (n=15 no-labor; n=12 labor). Activation of Caspase-1, IRS1/Akt, STAT, mTOR, and inflammatory signaling pathways was determined by Western blot. NFκB p65 and PPARγ DNA binding activity was measured in isolated nuclei. Results Labor increased Caspase-1 activation and mTOR complex 2 signaling, as measured by phosphorylation of Akt (S473). However, mTORC1 signaling was inhibited in response to labor as evidenced by decreased phosphorylation of mTOR (S2448) and 4EBP1 (T37/46 and T70). Labor also decreased NFκB and PPARγ DNA binding activity, while having no effect on IRS1 or STAT signaling pathway. Discussion and conclusion Several placental signaling pathways are affected by labor, which has implications for experimental design in studies of placental signaling. Inhibition of placental mTORC1 signaling in response to labor may serve to down-regulate protein synthesis and amino acid transport, processes that account for a large share of placental oxygen and glucose consumption. We speculate that this response preserves glucose and oxygen for transfer to the fetus during the stressful events of labor. PMID:25454472

Intersectionality at Work: Determinants of Labor Supply among Immigrant Latinas1

PubMed Central

Flippen, Chenoa

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.

To evaluate the efficacy of a close female relative providing emotional and physical support during active labor and birth. Randomized, two-group controlled clinical trial. Regional teaching hospital in the eastern part of Thailand with 782 beds. Primiparous women (N = 120) whose gestational ages were ≥ 36 weeks and who had uncomplicated pregnancies. Participants were randomly assigned to receive usual care and support from a chosen close female relative from admission until 2 hours after birth or usual care only. Within 24 hours of birth, labor outcomes (length of labor & type of birth) and levels of maternal satisfaction were assessed. Those in the experimental group had a significantly shorter duration of active labor and were more satisfied with their childbirth experiences than those in the control group. Differences between groups with respect to incidence of spontaneous delivery were not found. A close female relative was effective in providing supportive care during labor and delivery. The integration of this nursing intervention for women and their families at public hospitals in Thailand is supported. © 2012 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.

Psychiatric disorders and the labor market: an analysis by disorder profiles.

PubMed

Cowell, Alexander J; Luo, Zhehui; Masuda, Yuta J

2009-03-01

A key societal cost of mental illness is its impact on the labor market. In examining the relationship between psychiatric disorders and the labor market, the literature to date either examines psychiatric disorders in broad classes or focuses on the impact of specific conditions. The aim is to examine the relationships among meaningful profiles of concurrent past year disorders and labor market outcomes by gender. Data are from the National Epidemiologic Survey on Alcohol and Related Conditions for 2001/2002 (NESARC), a representative sample of the noninstitutionalized population aged 18 or older residing in the United States. The analysis sample contains 18,429 women and 16,426 men (unweighted). We examined the relationship between profiles of psychiatric disorders and three labor market outcomes: labor force participation; employment, conditional on labor force participation; and working full-time conditional on being employed. Because no attempt was made to control for potential endogeneity between the labor market outcomes and the psychiatric profiles, we are unable to establish the causal direction of the associations estimated. First, anxiety disorders among women appear to be associated with labor market outcomes (e.g., anxiety profile in employment outcome: OR=0.76, p<.05). Second, for employment among women large effects were seen for mood disorder and mood and anxiety; in contrast for men, these disorder profiles had significant associations with working full-time rather than employment. Third, for women, of the three labor market outcomes, employment status is particularly sensitive to the profiles of disorders. For men, no such pattern was found for any single labor market outcome. Concurrent psychiatric disorder profiles affect men and women differently in the labor market. The greatest differences are in (i) the relationship between labor market outcomes and profiles exhibiting anxiety disorders, and (ii) which labor market outcomes are influenced

Problem Plasma concentrations of fragment Bb (FBb) are a marker for activation of the alternative pathway of the complement system. High concentrations of FBb in maternal blood, as early as the first trimester, are associated with subsequent spontaneous preterm delivery <34 weeks of gestation. The study aim was to determine whether spontaneous preterm labor with intact membranes (PTL), intra-amniotic infection/inflammation (IAI) or labor at term are associated with alterations in circulating maternal FBb concentrations. Method of Study This cross-sectional study included women in the following groups: 1) non-pregnant (n=40); 2) normal pregnancy (gestational age range 20-36 6/7 weeks, n=63); 2) women at term not in labor (n=70); 3) women at term in spontaneous labor (n=59); 4) patients with an episode of PTL who delivered at term (n=62); 5) PTL without IAI who delivered preterm (n=30); and 6) PTL with IAI who delivered preterm (n=67). Maternal plasma FBb concentrations were determined by ELISA. Results 1) Among patients with PTL, those who had a preterm delivery either with IAI (1.21 μg/ml, IQR 0.77-2.16) or without IAI (1.13 μg/ml, IQR 0.92-2.08;) had a higher median maternal plasma FBb concentration than those who delivered at term (0.86 μg/ml, IQR 0.64-1.57; p=0.007 and p=0.026, respectively); 2) there was no difference in the median plasma FBb concentration between patients with and without IAI who delivered preterm (p=0.9); 3) in contrast, spontaneous labor at term was not associated with a significant change in the maternal plasma FBb concentration (p=0.8); 4) maternal plasma concentration of FBb did not differ significantly between normal pregnant women and the non-pregnant controls (p=0.8) and were not correlated with advancing gestational age (r −0.28, p=0.8). Conclusions 1) Preterm parturition is associated with activation of the alternative complement pathway in maternal circulation; 2) such activation is not detectable in spontaneous labor at term

Between hearth and labor market: the recruitment of peasant women in the Andes.

PubMed

Radcliffe, S A

1990-01-01

To cover subsistence requirements, peasant women from the Peruvian Andes increasingly are being forced to engage in income-generating activities, including domestic service, marketing, manufacturing, and herding. In many cases, recruitment into waged labor involves migration from rural communities. Case studies of the placement of peasant women in external labor markets illustrate the complex micro- and macro-level factors that determine the mix of productive and reproductive labor. The sexual division of labor in the domestic economy and community is the critical in regulating the length of absence of peasant women from the home, the types of jobs taken, and the migratory destination. In 1 such case study, 56 women from the village of Kallarayan (all of whom had migrated at some point) were interviewed during 13 months of fieldwork in 1984-85. There is no paid employment in Kallarayan, so 14% of the village's population is involved in migration to urban areas or commercial agricultural areas in jungle valleys at any point. Male migration is high in the 11-40-year age group, but becomes seasonal once men marry. Female migrants tend to remain away from the village for longer periods, but are almost exclusively single. Recruitment of peasant women into paid labor is achieved by 5 types of agents: family, godparents and friends, authority figures, recruiting agents, and employers. Peasant girls under 15 years of age tend to be allocated to external labor markets (largely domestic services) by parents and godparents; after 15 years, however, when children are considered to reach adulthood, there is a shift toward self-motivated migration or recruitment by employers and agents. The eldest daughter typically enters migration at age 14 years and sacrifices her education, while younger siblings remain in the home longer. In all but the poorest families, female migration for waged labor ends with marriage.

Caring for women in early labor: can we delay admission and meet women's needs?

PubMed

Marowitz, Amy

2014-01-01

Early labor poses challenges for women and their health care providers. Qualitative research shows that women may have a hard time determining when labor begins and when to seek care, are unprepared for the realities of this part of labor, find it difficult to manage early labor at home, and often desire admission before active labor. Yet a primary clinical management goal in early labor is the delay of admission until active labor. This is based on evidence that admission before active labor is associated with higher rates of cesarean birth and interventions such as oxytocin augmentation and epidural analgesia. The reasons for the higher rates of intervention are not known, but may include the effect of the hospital environment, inherent problems with the labor, misdiagnosis of active labor, provider impatience, and institutional policies not compatible with the care of women in early labor. Programs to decrease early admission have had mixed results. Thus, a tension exists between the goal of delaying admission until active labor in order to decrease the incidence of unnecessary interventions and women's difficulty with managing this part of labor at home. In this case report, the midwife provides a significant amount of care and support before admission through phone calls and outpatient visits; however, admission occurred prior to active labor. Supportive care continued in the hospital, and the labor and birth occurred with little intervention. Strategies that can be used to optimize the management and experience of early labor are presented. © 2014 by the American College of Nurse-Midwives.

Active Manual Movement Improves Directional Perception of Illusory Force.

PubMed

Amemiya, Tomohiro; Gomi, Hiroaki

2016-01-01

Active touch sensing is known to facilitate the discrimination or recognition of the spatial properties of an object from the movement of tactile sensors on the skin and by integrating proprioceptive feedback about hand positions or motor commands related to ongoing hand movements. On the other hand, several studies have reported that tactile processing is suppressed by hand movement. Thus, it is unclear whether or not the active exploration of force direction by using hand or arm movement improves the perception of the force direction. Here, we show that active manual movement in both the rotational and translational directions enhances the precise perception of the force direction. To make it possible to move a hand in space without any physical constraints, we have adopted a method of inducing the sensation of illusory force by asymmetric vibration. We found that the precision of the perceived force direction was significantly better when the shoulder is rotated medially and laterally. We also found that directional errors supplied by the motor response of the perceived force were smaller than those resulting from perceptual judgments between visual and haptic directional stimuli. These results demonstrate that active manual movement boosts the precision of the perceived direction of an illusory force.

Patellofemoral joint contact forces during activities with high knee flexion.

2012-03-01

The patellofemoral (PF) joint plays an essential role in knee function, but little is known about the in vivo loading conditions at the joint. We hypothesized that the forces at the PF joint exceed the tibiofemoral (TF) forces during activities with high knee flexion. Motion analysis was performed in two patients with telemetric knee implants during walking, stair climbing, sit-to-stand, and squat. TF and PF forces were calculated using a musculoskeletal model, which was validated against the simultaneously measured in vivo TF forces, with mean errors of 10% and 21% for the two subjects. The in vivo peak TF forces of 2.9-3.4 bodyweight (BW) varied little across activities, while the peak PF forces showed significant variability, ranging from less than 1 BW during walking to more than 3 BW during high flexion activities, exceeding the TF forces. Together with previous in vivo measurements at the hip and knee, the PF forces determined here provide evidence that peak forces across these joints reach values of around 3 BW during high flexion activities, also suggesting that the in vivo loading conditions at the knee can only be fully understood if the forces at the TF and the PF joints are considered together.

Evolution of division of labor: emergence of different activities among group members.

PubMed

Nakahashi, Wataru; Feldman, Marcus W

2014-05-07

The division of labor is an important component of the organization of human society. However, why this division evolved in hominids requires further investigation. Archeological evidence suggests that it appeared after the emergence of Homo sapiens and contributed to the great success of our species. We develop a mathematical model to investigate under what conditions division of labor should evolve. We assume two types of resources the acquisition of which demands different skills, and study the evolution of the strategy that an individual should use to divide its lifetime into learning and using each skill. We show that division of labor likely evolves when group size is large, skill learning is important for acquiring resources, and there is food sharing within a group. We also investigate division of labor by gender under the assumption that the genders have different efficiencies in acquiring each resource. We show that division of labor by gender likely evolves when skill learning is important and the difference in efficiencies between genders in acquiring resources is large. We discuss how the results of our analysis might apply to the evolution of division of labor in hominids. Copyright © 2014 Elsevier Ltd. All rights reserved.

Mapping Muscles Activation to Force Perception during Unloading

PubMed Central

Toma, Simone; Lacquaniti, Francesco

2016-01-01

It has been largely proved that while judging a force humans mainly rely on the motor commands produced to interact with that force (i.e., sense of effort). Despite of a large bulk of previous investigations interested in understanding the contributions of the descending and ascending signals in force perception, very few attempts have been made to link a measure of neural output (i.e., EMG) to the psychophysical performance. Indeed, the amount of correlation between EMG activity and perceptual decisions can be interpreted as an estimate of the contribution of central signals involved in the sensation of force. In this study we investigated this correlation by measuring the muscular activity of eight arm muscles while participants performed a quasi-isometric force detection task. Here we showed a method to quantitatively describe muscular activity (“muscle-metric function”) that was directly comparable to the description of the participants' psychophysical decisions about the stimulus force. We observed that under our experimental conditions, muscle-metric absolute thresholds and the shape of the muscle-metric curves were closely related to those provided by the psychophysics. In fact a global measure of the muscles considered was able to predict approximately 60% of the perceptual decisions total variance. Moreover the inter-subjects differences in psychophysical sensitivity showed high correlation with both participants' muscles sensitivity and participants' joint torques. Overall, our findings gave insights into both the role played by the corticospinal motor commands while performing a force detection task and the influence of the gravitational muscular torque on the estimation of vertical forces.

The current economic and social environment in the country are affecting the allied health professions in a variety of ways. The employment relationships in health care institutions also are being affected by historical and political pressures within the trade labor movement. While there is disagreement as to how these diverse pressures may evolve in the allied health professions, it is clear that assertive activity by parties on each side of the employment issue has the potential to create positive and effective resolution of differences, whether through collective or individual means. This dilemma facing the allied health professions and the principles of proactive labor relations are examined.

Active mechanics in living oocytes reveal molecular-scale force kinetics

Ahmed, Wylie; Fodor, Etienne; Almonacid, Maria; Bussonnier, Matthias; Verlhac, Marie-Helene; Gov, Nir; Visco, Paolo; van Wijland, Frederic; Betz, Timo

Unlike traditional materials, living cells actively generate forces at the molecular scale that change their structure and mechanical properties. This nonequilibrium activity is essential for cellular function, and drives processes such as cell division. Single molecule studies have uncovered the detailed force kinetics of isolated motor proteins in-vitro, however their behavior in-vivo has been elusive due to the complex environment inside the cell. Here, we quantify active forces and intracellular mechanics in living oocytes using in-vivo optical trapping and laser interferometry of endogenous vesicles. We integrate an experimental and theoretical framework to connect mesoscopic measurements of nonequilibrium properties to the underlying molecular- scale force kinetics. Our results show that force generation by myosin-V drives the cytoplasmic-skeleton out-of-equilibrium (at frequencies below 300 Hz) and actively softens the environment. In vivo myosin-V activity generates a force of F ~ 0 . 4 pN, with a power-stroke of length Δx ~ 20 nm and duration τ ~ 300 μs, that drives vesicle motion at vv ~ 320 nm/s. This framework is widely applicable to characterize living cells and other soft active materials.

The aim of this study was to investigate the effect of Lavender essence inhalation on severity of labor pain and duration of labor. This single-blind, randomized clinical trial was conducted on 120 pregnant women in two groups. The experimental group received 2 drops of Lavender essence inhaled at three stages (4-5, 6-7, 8-9 cm cervical dilation) and severity of the labor pain and duration of labor was measured before and after intervention. The control group was treated with distilled water as a placebo in the similar ways, too. The results showed that difference in the labor pain before and after intervention in two groups was significant (P = 0/001). But there was no difference in mean duration of the active phase and the second stage of labor between the two groups. Lavender essence aromatherapy may be an effective therapeutic option for pain management for women in labor. Published by Elsevier Ltd.

Stochastic Forecasting of Labor Supply and Population: An Integrated Model.

PubMed

Fuchs, Johann; Söhnlein, Doris; Weber, Brigitte; Weber, Enzo

2018-01-01

This paper presents a stochastic model to forecast the German population and labor supply until 2060. Within a cohort-component approach, our population forecast applies principal components analysis to birth, mortality, emigration, and immigration rates, which allows for the reduction of dimensionality and accounts for correlation of the rates. Labor force participation rates are estimated by means of an econometric time series approach. All time series are forecast by stochastic simulation using the bootstrap method. As our model also distinguishes between German and foreign nationals, different developments in fertility, migration, and labor participation could be predicted. The results show that even rising birth rates and high levels of immigration cannot break the basic demographic trend in the long run. An important finding from an endogenous modeling of emigration rates is that high net migration in the long run will be difficult to achieve. Our stochastic perspective suggests therefore a high probability of substantially decreasing the labor supply in Germany.

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.

To assess the effect of time of active pushing (TAP) on neonatal outcome. The study population (n=36,432) was taken from a Swedish randomized control trial on intrapartum monitoring, a European Union fetal electrocardiogram trial, and from Mölndal Hospital. After validation of acid-base samples and TAP, 22,812 cases were accepted for analysis. The median active TAP was 36 min for P0 and 13 min for P≥1 (P<0.001). After adjustments for parity, epidural, labor induction, birth weight, and gender, pushing for 15-29 min (n=6589) relative to pushing for <15 min (n=7264) increased the OR of a cord artery pH of <7.00 to 3.20 (95% CI 1.7-6.0), and that of a base deficit in extracellular fluid of >12 mmol/L to 3.5 (95% CI 1.3-9.0). The group with a cord artery pH of <7.00 had a longer TAP than the group with pH≥7.00: median (5th-95th percentile), 38 (9-107) min vs. 23 (5-87) min, P<0.001. The probability of a spontaneous vaginal delivery decreased significantly with every subsequent increase of 30 min in TAP (P<0.05). The risks of severe acidemia, metabolic acidosis, and deteriorated neonatal outcome gradually increased with the length of TAP (>15 min), while the probability of a spontaneous vaginal delivery decreased with the duration of pushing. We suggest active physiological evaluation of the labor progress together with continuous electronic fetal monitoring during pushing irrespective of guideline thresholds.

Work force policy perspectives: registered nurses.

Friss, L O

1981-01-01

If the decline in full-time labor force participation by registered nurses in hospitals is to be reversed, the issue of equal pay for comparable work must be addressed. Under pressure for cost containment, policies tend to focus on labor force economics rather than on limitations of services. While the two are interrelated, wage policies must be considered independently. This article describes the network which determines how nurse salaries are set: the relationship between the private sector, the general schedule and the Veteran's Administration. The effects of this system are documented, using testimony from a case in the tenth circuit, as well as comparisons with other reference groups: policemen, teachers, laborers, and VA career fields. The evidence suggests that there is a need for policy intervention. Prime areas for action are the comparability practices by governments, particularly in the areas of classification standards and pay setting. Hospital personnel practices which continue past effects of occupational segregation also should be changed.

Stray-Pedersen, Babill; Forsén, Lisa; Vangen, Siri

2017-01-01

Objective Our main objective was to investigate the association between duration of active labor and severe postpartum hemorrhage. We examined the effect of the total duration of active labor, the effect of each stage of active labor, and the gradient effect of duration of labor on severe postpartum hemorrhage. Methods A case-control study was generated from a source population of all women admitted for delivery at Oslo University Hospital and Drammen Hospital in Buskerud municipality during the time period January 1, 2008 to December 31, 2011. The study population included all cases of severe postpartum hemorrhage (n = 859) and a random sample of controls (n = 1755). Severe postpartum hemorrhage was defined as postpartum blood loss ≥1500 mL or need for blood transfusion. Prolonged labor was defined as duration of active labor >12 hours according to the definition of the World Health Organization. We used logistic multivariable regression in the analysis. Results We observed a significantly longer mean duration of labor in women who experienced severe postpartum hemorrhage compared to controls (5.4 versus 3.8 hours, p<0.001). Women with severe postpartum hemorrhage also had a longer duration of all stages of active labor compared to controls. The association between the duration of active labor and severe postpartum changed from a linear dose-response association to a threshold association after adjusting for augmentation with oxytocin, induction of labor, primiparity, and fever during labor. Compared to controls, women with severe postpartum hemorrhage were more likely to have a prolonged labor >12 hours (adjusted odds ratio = 2.44, 95% confidence interval: 1.69–3.53, p< 0.001). Conclusion Prolonged active labor (duration >12 hours) was associated with severe postpartum hemorrhage. Increased vigilance seems required when the labor is prolonged to reduce the risk of severe postpartum hemorrhage. PMID:28384337

Shadow Labor: Work and Wages among Immigrant Hispanic Women in Durham, North Carolina.

PubMed

Flippen, Chenoa A

2016-07-01

Drawing on data collected in Durham, NC, this paper examines the forces shaping the labor supply and wages of immigrant Hispanic women in new destinations. The analysis evaluates the role of human capital and immigration characteristics (including legal status), family structure, and immigrant-specific labor market conditions, such as subcontracting, in shaping labor market outcomes. Findings indicate that the main determinants of labor supply among immigrant Hispanic women in Durham relate to family structure, with human capital playing a relatively minor role. Important variation is observed, however, in the degree of work-family conflict across occupations. For wages, human capital and immigration characteristics (including documentation) are more determinant than family structure. Results highlight the extremely precarious position of immigrant Hispanic women in Durham's low wage labor market, and multiple, overlapping sources of disadvantage, particularly relating to legal status and family structure.

Objective To compare labor progression in twin vs singleton gestations. Study Design Retrospective review of electronic database created by Consortium on Safe Labor, reflecting labor and delivery information from 12 clinical centers 2002-2008. Women with twin gestations, cephalic presentation of presenting twin, gestational age ≥34 weeks, with ≥2 cervical examinations were included. Exclusion criteria were fetal anomalies or demise. Singleton controls were selected by the same criteria. Categorical variables were analyzed by χ2; continuous by Student t test. Interval censored regression was used to determine distribution for time of cervical dilation in centimeters, or “traverse times,” and controlled for confounding factors. Repeated-measures analysis constructed mean labor curves by parity and number of fetuses. Results A total of 891 twin gestations were compared with 100,513 singleton controls. Twin gestations were more often older, white or African American, earlier gestational age, increased prepregnancy body mass index, and with lower birthweight. There was no difference in number of prior cesarean deliveries, induction, or augmentation, or epidural use. Median traverse times increased at every centimeter interval in nulliparous twins, in both unadjusted and adjusted analysis (P < .01). A similar pattern was noted for multiparas in both analyses. Labor curves demonstrated a delayed inflection point in the labor pattern for nulliparous and multiparous twin gestations. Conclusion Both nulliparous and multiparous women have slower progression of active phase labor with twins even when controlling for confounding factors. PMID:23871795

A labor/leisure tradeoff in cognitive control.

PubMed

Kool, Wouter; Botvinick, Matthew

2014-02-01

Daily life frequently offers a choice between activities that are profitable but mentally demanding (cognitive labor) and activities that are undemanding but also unproductive (cognitive leisure). Although such decisions are often implicit, they help determine academic performance, career trajectories, and even health outcomes. Previous research has shed light both on the executive control functions that ultimately define cognitive labor and on a "default mode" of brain function that accompanies cognitive leisure. However, little is known about how labor/leisure decisions are actually made. Here, we identify a central principle guiding such decisions. Results from 3 economic-choice experiments indicate that the motivation underlying cognitive labor/leisure decision making is to strike an optimal balance between income and leisure, as given by a joint utility function. The results reported establish a new connection between microeconomics and research on executive function. They also suggest a new interpretation of so-called ego-depletion effects and a potential new approach to such phenomena as mind wandering and self-control failure.

Forces in inhomogeneous open active-particle systems.

We study the force that noninteracting pointlike active particles apply to a symmetric inert object in the presence of a gradient of activity and particle sources and sinks. We consider two simple patterns of sources and sinks that are common in biological systems. We analytically solve a one-dimensional model designed to emulate higher-dimensional systems, and study a two-dimensional model by numerical simulations. We specify when the particle flux due to the creation and annihilation of particles can act to smooth the density profile that is induced by a gradient in the velocity of the active particles, and find the net resultant force due to both the gradient in activity and the particle flux. These results are compared qualitatively to observations of nuclear motion inside the oocyte, that is driven by a gradient in activity of actin-coated vesicles.

2018-04-01

Active magnetic regenerators (AMR) have the potential for high efficiency cryogen liquefaction. One active magnetic regenerative liquefier (AMRL) configuration consists of dual magnetocaloric regenerators that reciprocate in a persistent-mode superconducting solenoid. Issues with this configuration are the spatial and temporal magnetization gradients that induce large magnetic forces and winding currents. To solve the coupled problem, we present a force minimization approach using passive magnetic material to balance a dual-regenerator AMR. A magnetostatic model is developed and simulated force waveforms are compared with experimental measurements. A genetic algorithm identifies force-minimizing passive structures with virtually ideal balancing characteristics. Implementation details are investigated which affirm the potential of the proposed methodology.

Active damping of modal vibrations by force apportioning

NASA Technical Reports Server (NTRS)

Hallauer, W. L., Jr.

1980-01-01

Force apportioning, a method of active structural damping based on that used in modal vibration testing of isolating modes by multiple shaker excitation, was analyzed and numerically simulated. A distribution of as few forces as possible on the structure is chosen so as to maximally affect selected vibration modes while minimally exciting all other modes. The accuracy of numerical simulations of active damping, active damping of higher-frequency modes, and studies of imperfection sensitivity are discussed. The computer programs developed are described and possible refinements of the research are examined.

The US healthcare workforce and the labor market effect on healthcare spending and health outcomes.

PubMed

Pellegrini, Lawrence C; Rodriguez-Monguio, Rosa; Qian, Jing

2014-06-01

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). Public and private healthcare spending also

Active electromagnetic invisibility cloaking and radiation force cancellation

NASA Astrophysics Data System (ADS)

Mitri, F. G.

2018-03-01

This investigation shows that an active emitting electromagnetic (EM) Dirichlet source (i.e., with axial polarization of the electric field) in a homogeneous non-dissipative/non-absorptive medium placed near a perfectly conducting boundary can render total invisibility (i.e. zero extinction cross-section or efficiency) in addition to a radiation force cancellation on its surface. Based upon the Poynting theorem, the mathematical expression for the extinction, radiation and amplification cross-sections (or efficiencies) are derived using the partial-wave series expansion method in cylindrical coordinates. Moreover, the analysis is extended to compute the self-induced EM radiation force on the active source, resulting from the waves reflected by the boundary. The numerical results predict the generation of a zero extinction efficiency, achieving total invisibility, in addition to a radiation force cancellation which depend on the source size, the distance from the boundary and the associated EM mode order of the active source. Furthermore, an attractive EM pushing force on the active source directed toward the boundary or a repulsive pulling one pointing away from it can arise accordingly. The numerical predictions and computational results find potential applications in the design and development of EM cloaking devices, invisibility and stealth technologies.

While there are well-accepted standards for the diagnosis of arrested active-phase labor, the definition of a "failed" induction of labor remains less certain. One approach to diagnosing a failed induction is based on the duration of the latent phase. However, a standard for the minimum duration that the latent phase of a labor induction should continue, absent acute maternal or fetal indications for cesarean delivery, remains lacking. The objective of this study was to determine the frequency of adverse maternal and perinatal outcomes as a function of the duration of the latent phase among nulliparous women undergoing labor induction. This study is based on data from an obstetric cohort of women delivering at 25 US hospitals from 2008 through 2011. Nulliparous women who had a term singleton gestation in the cephalic presentation were eligible for this analysis if they underwent a labor induction. Consistent with prior studies, the latent phase was determined to begin once cervical ripening had ended, oxytocin was initiated, and rupture of membranes had occurred, and was determined to end once 5-cm dilation was achieved. The frequencies of cesarean delivery, as well as of adverse maternal (eg, postpartum hemorrhage, chorioamnionitis) and perinatal (eg, a composite frequency of seizures, sepsis, bone or nerve injury, encephalopathy, or death) outcomes, were compared as a function of the duration of the latent phase (analyzed with time both as a continuous measure and categorized in 3-hour increments). A total of 10,677 women were available for analysis. In the vast majority (96.4%) of women, the active phase had been reached by 15 hours. The longer the duration of a woman's latent phase, the greater her chance of ultimately undergoing a cesarean delivery (P < .001, for time both as a continuous and categorical independent variable), although >40% of women whose latent phase lasted ≥18 hours still had a vaginal delivery.

Post-activation Potentiation in Propulsive Force after Specific Swimming Strength Training.

PubMed

Barbosa, A C; Barroso, R; Andries, O

2016-04-01

We investigated whether a conditioning activity (8×12.5 m with 2.5 min-interval using both hand paddles and parachute) induced post-activation potentiation in swimming propulsive force and whether a swimmer's force level affected a post-activation potentiation response. 8 competitive swimmers (5 males and 3 females, age: 18.4±1.3 years; IPS=796±56) performed a 10 s maximum tethered swimming test 8 and 4 min before (the highest value was considered as PRE), and 2.5 and 6.5 min after (POST1 and POST2, respectively) the conditioning activity. Rate of force development was not affected, but peak force in POST1 (p=0.02) and impulse in both POST1 (p=0.007) and POST2 (p=0.004) were reduced. Possibly the conditioning activity induced greater fatigue than post-activation potentiation benefits. For instance, the number of repetitions might have been excessive, and rest intervals between the conditioning activity and POST1 and POST2 were possibly too short. There were positive correlations between PRE peak force and changes in peak force and rate of force development. Although conditioning activity was detrimental, positive correlations suggest that weaker swimmers experience a deterioration of performance more than the stronger ones. This conditioning activity is not recommended for swimmers with the current competitive level before a competitive event. © Georg Thieme Verlag KG Stuttgart · New York.

Nonequilibrium forces following quenches in active and thermal matter.

Rohwer, Christian M; Solon, Alexandre; Kardar, Mehran; Krüger, Matthias

2018-03-01

Nonequilibrium systems with conserved quantities like density or momentum are known to exhibit long-ranged correlations. This, in turn, leads to long-ranged fluctuation-induced (Casimir) forces, predicted to arise in a variety of nonequilibrium settings. Here, we study such forces, which arise transiently between parallel plates or compact inclusions in a gas of particles, following a change ("quench") in temperature or activity of the medium. Analytical calculations, as well as numerical simulations of passive or active Brownian particles, indicate two distinct forces: (i) The immediate effect of the quench is adsorption or desorption of particles of the medium to the immersed objects, which in turn initiates a front of relaxing (mean) density. This leads to time-dependent density-induced forces. (ii) A long-term effect of the quench is that density fluctuations are modified, manifested as transient (long-ranged) (pair-)correlations that relax diffusively to their (short-ranged) steady-state limit. As a result, transient fluctuation-induced forces emerge. We discuss the properties of fluctuation-induced and density-induced forces as regards universality, relaxation as a function of time, and scaling with distance between objects. Their distinct signatures allow us to distinguish the two types of forces in simulation data. Our simulations also show that a quench of the effective temperature of an active medium gives rise to qualitatively similar effects to a temperature quench in a passive medium. Based on this insight, we propose several scenarios for the experimental observation of the forces described here.

Individual and Work Factors Related to Perceived Work Ability and Labor Force Outcomes

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 personal resources. Perceived work ability is a critical variable to study in the U.S., 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 three independent samples of U.S. working adults. Data regarding workers’ job characteristics were from self-report and O*NET 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 resources when perceived work ability was measured concurrently or two 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 three of these outcomes via perceived work ability. PMID:25314364

Labor force participation and fertility: a study of married women in Bangladesh.

PubMed

Miah, M M; Mizan, A N

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

A global perspective on foreign contract labor.

PubMed

Smart, J E; Casco, R R

1988-01-01

This paper provides a general overview on foreign contract labor. The growth in the use of foreign contract labor is described with reference to other types of international labor movements such as 1) illegal, undocumented, or irregular migration; 2) free migration; and 3) permanent settlement migration. Within this general context, the various national advantages and disadvantages of contract labor are outlined. Particular issues like the role of trade unions and the likely future international labor circulation are noted. The 1984 World Labour Report estimates a global stock of almost 22 million foreign workers. Despite lack of reliable data, the size of irregular labor flows is considerable. More than 4 million undocumented workers, primarily Mexicans, can be found in the US alone. Other major flows of illegal labor go from China to Hong Kong, Malaysia to Singapore, Columbia to Venezuela, and poor Arab countries to oil-exporting countries in the Middle East. Laws are often poorly enforced and contradictory. Employers often actively recruit illegal migrants. While permanent migration was formerly the primary source of foreign workers, the numbers migrating in this manner are decreasing significantly. In absolute terms, host countries gain considerably more through the use of contract labor than sending countries. The pervasive commitment of national governments to economic growth is a prime consideration in the decision to import foreign labor. In general, trade unions have created an environment wherein the use of foreign labor in the formal as opposed to the informal labor market is more difficult. The disadvantages of labor export include the costs of family separation, worker exploitation, and cultural alienation. Remittances constitute the most tangible return of labor export. In many countries they have made a very considerable impact on the balance of payments deficit.

Effect of sacrum-perineum heat therapy on active phase labor pain and client satisfaction: a randomized, controlled trial study.

2013-09-01

Reduction of labor pain is one of the most important aspects of obstetric care. Heat therapy, typically applied to the woman's back, lower abdomen, groin, and/or perineum during last stage of labor, is an easy pain relief method that does not require highly skilled care. The effectiveness of heat therapy applied to the perineum during the first stage of labor has not been evaluated. This study aimed to evaluate the effectiveness of heat therapy for pain and woman's satisfaction during physiological labor. Sixty primiparous women aged 18-35 years old were randomly assigned to heat therapy and control groups. Pain and satisfaction scores were measured by visual analog scale. The measurements of satisfaction were accomplished after birth. Data were analyzed by using the t-test and chi-square Mean pain scores in the heat therapy group were significantly lower than the control group (P < 0.05). The mean satisfaction score in the heat therapy group was significantly higher than in the control group (P < 0.05). Heat therapy, an inexpensive complementary treatment with low risk, can reduce the intensity of pain and increase mothers' satisfaction with care during the active phase of labor.

Study Design A retrospective cohort study of 208,695 electronic medical records from 19 hospitals across the United States, 2002–2008. Results Induction occurred in 42.9% of nulliparas and 31.8% of multiparas and elective or no recorded indication for induction at term occurred in 35.5% and 44.1%, respectively. Elective induction at term in multiparas was highly successful (vaginal delivery 97%) compared to nulliparas (76.2%). For all precursors, cesarean delivery was more common in nulliparas in the latent compared to active phase of labor. Regardless of method, vaginal delivery rates were higher with a ripe versus unripe cervix, particularly for multiparas (86.6 – 100%). Conclusions Induction of labor was a common obstetric intervention. Selecting appropriate candidates and waiting longer for labor to progress into the active phase would make an impact on decreasing the national cesarean delivery rate. PMID:22520652

Depletion forces exerted by self-propelled particles on circular and elliptical passive objects are studied using numerical simulations. We show that a bath of active particles can induce repulsive and attractive forces which are sensitive to the shape and orientation of the passive objects (either horizontal or vertical ellipses). The resultant force on the passive objects due to the active particles is studied as a function of the shape and orientation of the passive objects, magnitude of the angular noise, and distance between the passive objects. By increasing the distance between obstacles the magnitude of the repulsive depletion force increases, as long as such a distance is less than one active particle diameter. For longer distances, the magnitude of the force always decreases with increasing distance. We also found that attractive forces may arise for vertical ellipses at high enough area fraction.

Pathophysiology of preterm labor with intact membranes.

PubMed

Talati, Asha N; Hackney, David N; Mesiano, Sam

2017-11-01

Preterm labor with intact membranes is a major cause of spontaneous preterm birth (sPTB). To prevent sPTB a clear understanding is needed of the hormonal interactions that initiate labor. The steroid hormone progesterone acting via its nuclear progesterone receptors (PRs) in uterine cells is essential for the establishment and maintenance of pregnancy and disruption of PR signaling (i.e., functional progesterone/PR withdrawal) is key trigger for labor. The process of parturition is also associated with inflammation within the uterine tissues and it is now generally accepted that inflammatory stimuli from multiple extrinsic and intrinsic sources induce labor. Recent studies suggest inflammatory stimuli induce labor by affecting PR transcriptional activity in uterine cells to cause functional progesterone/PR withdrawal. Advances in understanding the functional interaction of inflammatory load on the pregnancy uterus and progesterone/PR signaling is opening novel areas of research and may lead to rational therapeutic strategies to effectively prevent sPTB.

Energy cost of isometric force production after active shortening in skinned muscle fibres.

PubMed

Joumaa, Venus; Fitzowich, Alex; Herzog, Walter

2017-04-15

The steady-state isometric force after active shortening of a skeletal muscle is lower than the purely isometric force at the corresponding length. This property of skeletal muscle is known as force depression. The purpose of this study was to investigate whether the energy cost of force production at the steady state after active shortening was reduced compared with the energy cost of force production for a purely isometric contraction performed at the corresponding length (same length, same activation). Experiments were performed in skinned fibres isolated from rabbit psoas muscle. Skinned fibres were actively shortened from an average sarcomere length of 3.0 µm to an average sarcomere length of 2.4 µm. Purely isometric reference contractions were performed at an average sarcomere length of 2.4 µm. Simultaneously with the force measurements, the ATP cost was measured during the last 30 s of isometric contractions using an enzyme-coupled assay. Stiffness was calculated during a quick stretch-release cycle of 0.2% fibre length performed once the steady state had been reached after active shortening and during the purely isometric reference contractions. Force and stiffness following active shortening were decreased by 10.0±1.8% and 11.0±2.2%, respectively, compared with the isometric reference contractions. Similarly, ATPase activity per second (not normalized to the force) showed a decrease of 15.6±3.0% in the force-depressed state compared with the purely isometric reference state. However, ATPase activity per second per unit of force was similar for the isometric contractions following active shortening (28.7±2.4 mmol l -1  mN -1  s mm 3 ) and the corresponding purely isometric reference contraction (30.9±2.8 mmol l -1  mN -1  s mm 3 ). Furthermore, the reduction in absolute ATPase activity per second was significantly correlated with force depression and stiffness depression. These results are in accordance with the idea that force

Activating catalysts with mechanical force.

Homogeneously catalysed reactions can be 'switched on' by activating latent catalysts. Usually, activation is brought about by heat or an external chemical agent. However, activation of homogeneous catalysts with a mechanical trigger has not been demonstrated. Here, we introduce a general method to activate latent catalysts by mechanically breaking bonds between a metal and one of its ligands. We have found that silver(I) complexes of polymer-functionalized N-heterocyclic carbenes, which are latent organocatalysts, catalyse a transesterification reaction when exposed to ultrasound in solution. Furthermore, ultrasonic activation of a ruthenium biscarbene complex with appended polymer chains results in catalysis of olefin metathesis reactions. In each case, the catalytic activity results from ligand dissociation, brought about by transfer of mechanical forces from the polymeric substituents to the coordination bond. Mechanochemical catalyst activation has potential applications in transduction and amplification of mechanical signals, and mechanically initiated polymerizations hold promise as a novel repair mechanism in self-healing materials.

Labor unions in medicine: the intersection of patient advocacy and self-advocacy.

PubMed

Manthous, Constantine A

2014-05-01

Labor unions have been a weak force in the medical marketplace. To briefly review the history of physicians' and nurses' labor unions, explore the ethics of unions in medicine, and offer a solution that simultaneously serves patients and professionals. A selective review of the literature. Labor unions of medical professionals pose an ethical quandary, that is a tension between selfless patient advocacy versus self-advocacy. The primary role of labor unions has been to extract from management benefits for employees. The threat of work actions is the primary tool that labor unions can apply to encourage management to negotiate mutually acceptable conditions of employment. Work actions-namely slow-downs and strikes-may harm patients and may therefore run afoul of professionals' primary duty to the primacy of patients' welfare. An alternative model is offered wherein medical unions align self-centered and patient-centered interests and leverage the Public Good, in the form of public opinion, to encourage good-faith bargaining with management. As medicine becomes increasingly corporatized, physicians will join nurses in "at-will employment" arrangements whereby self-advocacy and patient advocacy may be impacted. Although labor unions have been a means of counterbalancing unchecked discretion of corporate management, conventional labor unions may run afoul of medical ethical principles. Reconsideration and innovation, to address this ethical dilemma, could provide a solution that aligns both clinicians' and patients' welfare.

Young Finnish Unemployed Men's Experiences of Having Participated in a Specific Active Labor Market Program.

Björklund, Ove; Häggström, Elisabeth; Nyström, Lisbet

2017-09-01

The purpose of the present study was to describe young Finnish unemployed men's experiences of having participated in a specific active labor market program, intended to fight unemployment and offered at a resource center. Fifteen young unemployed Finnish men in the age range 18 to 27 years were interviewed face-to-face. Purposive sampling was used to increase the variation among informants. The interview texts were analyzed using both manifest and latent qualitative content analysis. The present results reported that the young men felt that they, thanks to the program at the resource center, had acquired daily routines and could ultimately believe in the future. The young men described how they now had a structure, economic support, and that they could return to their daily life. The informants also described how they could see new possibilities and believe in oneself. There is a lack of empirical studies assessing the possible impact of active labor market programs on the unemployed based on participants' own experiences. Further research is needed to describe and elucidate in more detail the effects of targeted support measures and the needs of unemployed men of different ages and living in different contexts.

To estimate the incidence of dystocia among nulliparous women without apparent co-morbidity and to examine maternal and fetal short-term outcomes after dystocia. A multi-center cohort study with prospectively collected data. Nine obstetric departments with annual birth rates between 850 and 5,400. Low-risk nulliparous women in term spontaneous labor with a singleton fetus in cephalic presentation. Follow-up of 2,810 nulliparas using self-administered questionnaires supplemented with clinical records. CRITERIA FOR DYSTOCIA: Cervical dilatation < or =2 cm over four hours during the first stage of labor or no descent during two hours (three hours with epidural analgesia) in the descending phase of second stage or no progress for one hour during the expulsive phase of the second stage. Inclusion took place between May 2004 and July 2005. Incidences of dystocia, maternal, and fetal outcomes. The cumulative incidence of dystocia was 37% and of the diagnoses 61% were given in the second stage of labor. Women with dystocia treated by augmentation had more cesarean and ventouse deliveries, more often non-clear amniotic fluid, more post-partum hemorrhage and their children were more often given low one-minute neonatal Apgar scores as compared to women delivered without a diagnosis of dystocia. A dystocia incidence of 37% was found in healthy term nulliparas with no indication for induction or elective cesarean delivery. The adverse maternal and neonatal birth outcomes may be related to the cause of dystocia or to augmentation of labor and this question calls for further studies.

Returning migrant characteristics and labor market demand in Greece.

Petras, E M; Kousis, M

1988-01-01

Immigrants who repatriate bring with them modern work skills which many observers in labor exporting regions describe as a great contribution to the mother country. Using data from 2 samples of Greek repatriates as well as projections of industrial labor force demands in Greece for the 1980s, this article challenges this concept. The authors find that the uneven regional development and stunted industrial growth which pushed these workers abroad are also responsible for the narrowly limited employment options which they face once they repatriate. For the urban repatriate, the market is limited to unemployment, the urban informal sector and scattered jobs, while for the rural repatriate, small-scale agriculture, multiple job holdings and unemployment are the only viable options.

Constrained handgrip force decreases upper extremity muscle activation and arm strength.

Smets, Martin P H; Potvin, James R; Keir, Peter J

2009-09-01

Many industrial tasks require repetitive shoulder exertions to be performed with concurrent physical and mental demands. The highly mobile nature of the shoulder predisposes it to injury. The purpose of this study was to determine the effects of simultaneous gripping, at a specified magnitude, on muscle activity and maximal arm force in various directions. Ten female subjects performed maximal arm exertions at two different heights and five directions using both specified (30% maximum voluntary grip) and preferred (self-selected) grip forces. Electromyography was recorded from eight muscles of the right upper extremity. The preferred grip condition produced grip forces that were dependent on the combination of arm height and force direction and were significantly greater (arm force down), lower (to left, up and push forward), or similar to the specified grip condition. Regardless of the magnitude of the preferred grip force, specifying the grip resulted in decreased maximal arm strength (by 18-25%) and muscle activity (by 15-30%) in all conditions, indicating an interfering effect when the grip force was specified by visual target force-matching. Task constraints, such as specific gripping demands, may decrease peak force levels attainable and alter muscle activity. Depending on the nature of task, the amount of relative demand may differ, which should be considered when determining safety thresholds.

Many strategies for labor pain management have been studied, including aromatherapy, which is a noninvasive, alternative medicine used as an adjunct for labor pain control. Nevertheless, the results were contradictory. Therefore, we conducted this study to determine the effectiveness of aromatherapy for reducing pain during labor. A randomized controlled trial was carried out on Thai laboring primigravidae who were a low-risk singleton pregnancy undergoing vaginal delivery. All participants, both study and control group, received standard obstetric care. Aromatherapy was only provided to the study group during the first stage of labor. The women rated their pain intensity by rating scales at different stages of labor. The primary outcome was pain scores and the secondary outcomes were necessity of painkiller usage, labor time, aromatherapy-associated complications, route of delivery, and Apgar scores. A total of 104 women were recruited, 52 in each group. Baseline characteristics and baseline pain scores were comparable. The median pain score of latent and early active phase was lower in the aromatherapy group, 5 vs 6 and 7 vs 8, respectively. The mean differences of pain scores between latent and early active phase and the baseline were significantly lower in the aromatherapy group, 1.88 vs 2.6 (p = 0.010) and 3.82 vs 4.39 (p = 0.031), respectively. Late active phase pain scores and other perinatal outcomes were not significantly different. Aromatherapy is helpful in reducing pain in latent and early active phase, and can probably be used as an adjunctive method for labor pain control without serious side effects.

A pesticide exposure assessment pilot study was conducted in Salinas Valley, California during September, 1993. The pilot study had two main purposes: 1) to develop general methodologies for videotaping micro-activities of a population, and 2) to collect an initial database of activity patterns of two- to four-year-old farm labor children. Tools to accurately determine exposure and dose through all three pathways (dermal, ingestion, and inhalation) are needed to effectively assess and manage health risks posed by pesticides and other environmental pollutants. Eight to ten hours of videotape data were collected for each of four Mexican-American farm labor children. In addition, the researchers administered a day-after recall questionnaire to the caregivers of the children to test (for the study sample) the hypothesis that recall questionnaires are inadequate for collecting detailed information regarding dermal and hand-to-mouth exposures. The results of this study provide the first detailed set of videotape data on farm labor children, a population at high risk to pesticide exposures. In addition, this is the first project in the exposure assessment field to use direct observation videotaping for collecting micro-activity data in order to quantify dermal and ingestion exposure. The comparison of caregivers' recall of children's activities to actual videotapes from the pilot study supports the hypothesis that videotaping may greatly improve the accuracy of activity information used to compute dermal and ingestion exposures. However, as it was clear that the researchers' presence in some cases altered the activities of the subjects, further experiments need to be conducted to minimize interference of videotaping on exposure-related activities. This paper explains the selection of the study population, the methods used to implement the pilot study, and the lessons learned. While the discussion focuses on four case studies in the Mexican-American farm labor population

Labor dystocia (slow or difficult labor or birth) is the most commonly diagnosed aberration of labor and the most frequently documented indication for primary cesarean birth. Yet, dystocia remains a poorly specified diagnostic category, with determinations often varying widely among clinicians. The primary aims of this review are to 1) summarize definitions of active labor and dystocia, as put forth by leading professional obstetric and midwifery organizations in world regions wherein English is the majority language and 2) describe the use of dystocia and related terms in contemporary research studies. Major national midwifery and obstetric organizations from qualifying United Nations-member sovereign nations and international organizations were searched to identify guidelines providing definitions of active labor and dystocia or related terms. Research studies (2000-2013) were systematically identified via PubMed, MEDLINE, and CINAHL searches to describe the use of dystocia and related terms in contemporary scientific publications. Only 6 organizational guidelines defined dystocia or related terms. Few research teams (n = 25 publications) defined dystocia-related terms with nonambiguous clinical parameters that can be applied prospectively. There is heterogeneity in the nomenclature used to describe dystocia, and when a similar term is shared between guidelines or research publications, the underlying definition of that term is sometimes inconsistent between documents. Failure to define dystocia in evidence-based, well-described, clinically meaningful terms that are widely acceptable to and reproducible among clinicians and researchers is concerning at both national and global levels. This failure is particularly problematic in light of the major contribution of this diagnosis to primary cesarean birth rates. © 2015 by the American College of Nurse-Midwives.

Optimal integral force feedback for active vibration control

NASA Astrophysics Data System (ADS)

Teo, Yik R.; Fleming, Andrew J.

2015-11-01

This paper proposes an improvement to Integral Force Feedback (IFF), which is a popular method for active vibration control of structures and mechanical systems. Benefits of IFF include robustness, guaranteed stability and simplicity. However, the maximum damping performance is dependent on the stiffness of the system; hence, some systems cannot be adequately controlled. In this paper, an improvement to the classical force feedback control scheme is proposed. The improved method achieves arbitrary damping for any mechanical system by introducing a feed-through term. The proposed improvement is experimentally demonstrated by actively damping an objective lens assembly for a high-speed confocal microscope.

Little is known about mechanics underlying the interaction among platelets during activation and aggregation. Although the strength of a blood thrombus has likely major biological importance, no previous study has measured directly the adhesion forces of single platelet-platelet interaction at different activation states. Here, we filled this void first, by minimizing surface mediated platelet-activation and second, by generating a strong adhesion force between a single platelet and an AFM cantilever, preventing early platelet detachment. We applied our setup to measure rupture forces between two platelets using different platelet activation states, and blockade of platelet receptors. The rupture force was found to increase proportionally to the degree of platelet activation, but reduced with blockade of specific platelet receptors. Quantification of single platelet-platelet interaction provides major perspectives for testing and improving biocompatibility of new materials; quantifying the effect of drugs on platelet function; and assessing the mechanical characteristics of acquired/inherited platelet defects.

Urbanization, economic development and health: evidence from China's labor-force dynamic survey.

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.

History of fast labor is currently subjectively defined and inductions for non-medical indications are becoming restricted. We hypothesized that women induced for a history of fast labor do not have faster previous labors and do not deliver more quickly. A retrospective case-control cohort design studied multiparas undergoing elective induction at one high risk center. Outcomes of dyads electively induced for a history of previous fast labor indication (PFast) were compared to controls with a psychosocial indication. A total of 612 elective inductions with 1074 previous deliveries were evaluated: 81 (13%) PFast and 531 (87%) control. PFast had faster previous labors (median 5.5 h, IQR: 4.5-6) versus. control (10 h, IQR: 9-10.5; p < 0.001). Subsequent delivery time from start to expulsion was shorter for PFast (median 7 h, IQR: 5-9, p < 0.001) than controls with and without a previous labor <5.5 h (8.6 h, IQR: 6-14 and 9.5 h, IQR: 7-15, respectively). PFast were less likely to have a serious maternal complication. Neonatal complications were similar. Patients induced for a history of fast labor do have faster previous labors, suggesting a significant history of fast labor can be defined as <5.5 h. These women deliver more quickly and with lower morbidity than controls when subsequently induced, therefore the benefit may warrant the risk for a select number of women with a history of a prior labor length <5.5 h.

Background This paper addresses the problem of wastage of the qualified labor force, which takes place both during the education process and when trained personnel try to find jobs in the local market. Methods Secondary sources were used, mainly the Statistical yearbooks of the National Association of Universities and Higher Education Institutions (ANUIES in Spanish). Also, the 2000 Population Census was used to estimate the different sources of labor market wastage. The formulas were modified to estimate educational and labor wastage rates. Results Out of every 1000 students who started a medical training in 1996, over 20% were not able to finish the training by 2000. Furthermore, out of every 1000 graduates, 31% were not able to find a remunerated position in the labor market that would enable them to put into practice the abilities and capacities obtained at school. Important differences can be observed between generalists and specialists, as well as between men and women. In the case of specialists and men, lower wastage rates can be observed as compared to the wastage rates of generalists and women. A large percentage of women dedicate themselves exclusively to household duties, which in labor terms represents a wastage of their capacity to participate in the production of formal health services. Conclusion Women are becoming a majority in most medical schools, yet their participation in the labor market does not reflect the same trend. Among men, policies should be formulated to incorporate doctors in the specific health field for which they were trained. Regarding women, specific policies should target those who are dedicated full-time to household activities in order to create the possibility of having them occupy a remunerated job if they are willing to do so. Reducing wastage at both the educational and labor levels should improve the capacity of social investment, thereby increasing the capacity of the health system as a whole to provide services

METHODS: Secondary sources were used, mainly the Statistical yearbooks of the National Association of Universities and Higher Education Institutions (ANUIES in Spanish). Also, the 2000 Population Census was used to estimate the different sources of labor market wastage. The formulas were modified to estimate educational and labor wastage rates. RESULTS: Out of every 1000 students who started a medical training in 1996, over 20% were not able to finish the training by 2000. Furthermore, out of every 1000 graduates, 31% were not able to find a remunerated position in the labor market that would enable them to put into practice the abilities and capacities obtained at school. Important differences can be observed between generalists and specialists, as well as between men and women. In the case of specialists and men, lower wastage rates can be observed as compared to the wastage rates of generalists and women. A large percentage of women dedicate themselves exclusively to household duties, which in labor terms represents a wastage of their capacity to participate in the production of formal health services. CONCLUSION: Women are becoming a majority in most medical schools, yet their participation in the labor market does not reflect the same trend. Among men, policies should be formulated to incorporate doctors in the specific health field for which they were trained. Regarding women, specific policies should target those who are dedicated full-time to household activities in order to create the possibility of having them occupy a remunerated job if they are willing to do so. Reducing wastage at both the educational and labor levels should improve the capacity of social investment, thereby increasing the capacity of the health system as a whole to provide services

To evaluate discrimination of clinical parameters and ultrasound examination to differentiate "false labor" and "true labor". In a prospective study during a period of 6 months, a total of 178 patients in term (37-41 weeks) consulting our obstetric unit for uterine contraction, were enrolled. Patients were examined separately by a midwife and a resident and separated into "true labor group" and "false labor group". The clinical characteristics of true versus false labor patients were compared. ROC curves were developed to determine an optimal cervical length and uterocervical angle for prediction of true labor. The prevalence of real labor was 57.3%. Patients who were in true labor had more painful and more frequent contractions. The "true labor" group had shorter cervical length and larger uterocervical angle. The optimal CL cut-off was 1.4mm with a specificity of 73% (RR 4.3, sensibility 63%, PPV 14%, NPV 95%). The optimal UCA cut off was 123° (RR 6.7, sensitivity 50%, specificity of 83%, PPV 10%, NPV 96%). The best performance was demonstrated by combined testing, yielding LHR+ that rich 13. In this study, we reported a new application of ultrasound to identify false labor and avoid unnecessary hospitalization with obstetric and adverse economic impacts.

Does cancer reduce labor market entry? Evidence for prime-age females.

PubMed

Moran, John R; Short, Pamela Farley

2014-06-01

Existing studies of the labor market status of cancer survivors have focused on the extent to which cancer disrupts the employment of individuals who were working when diagnosed with cancer. We examine how surviving cancer affects labor market entry and usual hours of work among females aged 28 to 54 years who were not working when first diagnosed. We find that prime-age females have employment rates 2 to 6 years after diagnosis that are 12 percentage points lower than otherwise similar women who were initially out of the labor force, full-time employment rates that are 10 percentage points lower, and usual hours of work that are 5 hours per week lower. These estimates are somewhat larger than estimates for prime-age women employed at the time of diagnosis and highlight the importance of considering nonworking females when assessing the economic and psychosocial burden of cancer.

Decrement of uterine myometrial burst duration as a correlate to active labor: a Hilbert phase approach.

We propose a novel approach based on Hilbert phase to identify the burst in the uterine myometrial activity. We apply this approach to 24 serial magnetomyographic signals recorded from four pregnant women using a 151 SQUID array system. The bursts identified with this approach are evaluated for duration and are correlated with the gestational age. In all four subjects, we find a decrease in the duration of burst as the subject approaches active labor. As was shown in animal studies, this result indicates a faster conduction time between the muscle cells which activate a larger number of muscle units in a synchronous manner.

Remedies to the problem of child labor: the situation in the apparel industry.

Mazur, J

When you realize how long the problem of child labor has been around, anyone who ventures into the terrain of remedies obviously needs a long memory and not a little optimism. What have we tried? What has worked? And what has not worked? To answer these questions, we must first look at how we have diagnosed the problem. Some say that the return of child labor is due to the present recession. Hard-pressed businesses are looking for cheap and cheaper labor. Sweatshops proliferate. When the recession recedes, so will child labor. If it were that simple, we could all congratulate ourselves on having conducted this enlightened symposium and go home without worrying much more about the problem. The magic hand of the market, in due course, will straighten it all out. Let me tell you something about the apparel industry in New York where new laws and strict enforcement make the only difference. Over 80% of OSHA inspections were triggered by the state's Apparel Task Force.

Background: This study aimed to calculate the child labor rate and establish the factors affecting this phenomenon in the less developed provinces of Iran. Methods: This study has used the secondary data of population and housing census gathered by Iranian Statistical Center in 2011. The data belonged to 14859 children between 10 and 14 of 9 less developed provinces of Iran. A multiple regression model was hypothesized drawing on related literature and accordingly using data; the logistic regression was estimated. Data cleaning process was also conducted prior to the analysis. Results: The child labor force participation rate for all children between 10 and 14 years old was 1.7%, of which boys’ child labor rate was higher than girls’ (2.4% over 1%). As such, the mothers’ fertility rate and education were of the strongest, yet converse, effect on child labor supply in the country. Conclusion: A little proportion of children in less developed regions of Iran was suffering from child labor. However, given the diminishing and rising effects of, respectively, variables such as mothers’ literacy and working on the child labor; the authorities could restrict child labor attending more to such a group. The factors identified could also be of a high value for the policy-makers at both national and international level such as the Health and Welfare ministries, EMRO, ILO and UNICEF. PMID:26587499

Forced underwater laminar flows with active magnetohydrodynamic metamaterials

Theory and practical implementations for wake-free propulsion systems are proposed and proven with computational fluid dynamic modeling. Introduced earlier, the concept of active hydrodynamic metamaterials is advanced by introducing magnetohydrodynamic metamaterials, structures with custom-designed volumetric distribution of Lorentz forces acting on a conducting fluid. Distributions of volume forces leading to wake-free, laminar flows are designed using multivariate optimization. Theoretical indications are presented that such flows can be sustained at arbitrarily high Reynolds numbers. Moreover, it is shown that in the limit Re ≫102 , a fixed volume force distribution may lead to a forced laminar flow across a wide range of Re numbers, without the need to reconfigure the force-generating metamaterial. Power requirements for such a device are studied as a function of the fluid conductivity. Implications to the design of distributed propulsion systems underwater and in space are discussed.

Evidence-based clinical hypnosis for obstetrics, labor and delivery, and preterm labor.

PubMed

Brown, Donald Corey; Hammond, D Corydon

2007-07-01

This paper reviews the benefits and effectiveness of hypnosis in obstetrics and labor and delivery, demonstrating significant reductions in the use of analgesics and anesthesia and in shorter Stages 1 and 2 labors. It presents empirical and theoretical rationales for use of hypnosis in preterm labor (PTL) and labor and delivery at term. The benefits of hypnosis in relation to labor length, pain levels, and the enjoyment of labor, as well as its effectiveness in preterm labor are noted in randomized controlled trials and in a meta-analysis. Risk factors are reported for preterm delivery; hypnosis significantly prolongs pregnancy. Six cases are presented of hypnosis stopping PTL a number of times and when indicated at term. A case report of successful use of hypnosis in quadruplets is presented with some scripts. Suggestions are made for further research.

Health, Enterprise, and Labor Complementarity in the Household*

We study the role of household enterprise as a coping mechanism after health shocks. Using variation in the cost of traveling to formal sector health facilities to predict recovery from acute illness in Tanzania, we show that individuals with prolonged illness switch from farm labor to enterprise activity. This response occurs along both the extensive (entry) and intensive (capital stock and labor supply) margins. Family members who are not ill exhibit exactly the same pattern of responses. Deriving a simple extension to the canonical agricultural household model, we show that our results suggest complementarities in household labor. PMID:28943705

Negative emotions facilitate isometric force through activation of prefrontal cortex and periaqueductal gray.

PubMed

Blakemore, Rebekah L; Rieger, Sebastian W; Vuilleumier, Patrik

2016-01-01

Emotions are considered to modulate action readiness. Previous studies have demonstrated increased force production following exposure to emotionally arousing visual stimuli; however the neural mechanisms underlying how precise force output is controlled within varying emotional contexts remain poorly understood. To identify the neural correlates of emotion-modulated motor behaviour, twenty-two participants produced a submaximal isometric precision-grip contraction while viewing pleasant, unpleasant, neutral or blank images (without visual feedback of force output). Force magnitude was continuously recorded together with change in brain activity using functional magnetic resonance imaging. Viewing unpleasant images resulted in reduced force decay during force maintenance as compared with pleasant, neutral and blank images. Subjective valence and arousal ratings significantly predicted force production during maintenance. Neuroimaging revealed that negative valence and its interaction with force output correlated with increased activity in right inferior frontal gyrus (rIFG), while arousal was associated with amygdala and periaqueductal gray (PAG) activation. Force maintenance alone was correlated with cerebellar activity. These data demonstrate a valence-driven modulation of force output, mediated by a cortico-subcortical network involving rIFG and PAG. These findings are consistent with engagement of motor pathways associated with aversive motivation, eliciting defensive behaviour and action preparedness in response to negative emotional signals.

To define the management of preterm labor (MAP). The literature search was conducted using computer databases Medline and the Cochrane Library for a period from 1969 to March 2016. Leukocytosis screening may be useful in case of hospitalization for Preterm labor (PTL). Its use is not routine (professional consensus). Screening for urinary tract infection by urine culture should be systematic and antibiotic treatment should be performed in cases of bacterial colonization or urinary tract infection for a period of 7 days (grade A). The vaginal swab is useful to detect a strep B and was prescribed antibiotics during labor if positive (grade A). Routine antibiotic therapy is not recommended in case of PTL (grade A). Prolonged hospitalization does not reduce the risk of preterm delivery (NP3) and is not recommended (grade B). Bed rest does not reduce the risk of PTL (NP3), increases the risk of thromboembolism (NP3), and is not recommended (grade C). After hospitalization for PTL, a regular visit by a caregiver at home may be helpful when patients belong to a precarious environment or are psychologically vulnerable (Professional consensus). The benefit of monitoring home uterine activity repeated in the aftermath of hospitalization for PTL is not shown (NP3). It is not recommended to follow-up uterine activity systematically after hospitalization for PTL (grade C). The management of PTL should be individualized, include searching and treatment of infection and avoid prolonged hospitalization or bed rest. Copyright © 2016 Elsevier Masson SAS.

Background Beta-2-adrenergic receptor (β2AR) activity influences labor and its genotype affects the incidence of preterm delivery. We determined the effect of β2AR genotype on term labor progress and pain. Methods We prospectively enrolled 150 nulliparous parturients in the third trimester and obtained sensory thresholds, demographic information and DNA. Cervical dilation, pain scores and labor management data were extracted with associated times. The association of genetic and demographic factors with labor was tested with mixed effects models. Results Parturients who express Gln at the 27 position of the β2AR had slower labor (P<0.03). They progressedfrom 1–10cm dilation in approximately 21 hours compared to 14 hours in otherpatients. Asian ethnicity, previously associated with slower labor, is highly associated with this polymorphism (P<0.0001). Heavier and Black patients had slower latent labor (P<0.01, 0.01) and neuraxial analgesia was associated with slower labor progress (P<0.0001). It could take up to 36 hours for the heaviest and the Black parturients to transition from 1cm cervical dilation to active labor; however once the active phase began, labor rate was the same as other patients’. Conclusion We detected a strong association between β2AR genotype and slower labor. Asian ethnicity may be a proxy for β2AR genotype. Black and heavy women have slower latent labor. These results confirm many of the associations found when this mathematical model was applied to a large retrospectivecohort, further validating this approach to description and analysis of labor progress.

Hypomethylated cell-free DNA from senescent placental trophoblasts may be involved in the activation of the inflammatory cascade to initiate labor. To determine the changes in cell-free DNA concentrations, the methylation ratio, and inflammatory markers between women in labor at term vs women without labor. In this prospective cohort study, eligible participants carried a nonanomalous singleton fetus. Women with major medical comorbidity, preterm labor, progesterone use, aneuploidy, infectious disease, vaginal bleeding, abdominal trauma, or invasive procedures during the pregnancy were excluded. Maternal blood samples were collected at 28 weeks, 36 weeks, and at admission for delivery. Total cell-free DNA concentration, methylation ratio, and interleukin-6 were analyzed. The primary outcome was the difference in methylation ratio in women with labor vs without labor. Secondary outcomes included the longitudinal changes in these biomarkers corresponding to labor status. A total of 55 women were included; 20 presented in labor on admission and 35 presented without labor. Women in labor had significantly greater methylation ratio (P = .001) and interleukin-6 (P < .001) on admission for delivery than women without labor. After we controlled for body mass index and maternal age, methylation ratio (adjusted relative risk, 1.38; 95% confidence interval, 1.13 to 1.68) and interleukin-6 (adjusted relative risk, 1.12, 95% confidence interval, 1.07 to 1.17) remained greater in women presenting in labor. Total cell-free DNA was not significantly different in women with labor compared with women without. Longitudinally, total cell-free DNA (P < .001 in labor, P = .002 without labor) and interleukin-6 (P < .001 in labor, P = .01 without labor) increased significantly across gestation in both groups. The methylation ratio increased significantly in women with labor from 36 weeks to delivery (P = .02). Spontaneous labor at term is associated with a greater cell-free DNA

Pushing in labor: performance and not endurance.

2002-06-01

It is believed that delivery is faster if women are instructed to voluntarily bear down in synchrony with their uterine contractions. Confronted by the large variance in the duration of the second stage of labor, many clinicians attribute a "fast" or a "short" expulsion time solely to the patient's willingness to cooperate or to the strength of epidural anesthesia if it is a factor. Yet, knowledge of pushing performance and the factors affecting it remain limited. We investigated the maternal, fetal, and labor characteristics that influence the maternal "pushing performance" and sought to design a predictive index that prospectively identified "high" versus "low" pushing performers. Intrauterine pressure (IP) was prospectively measured during the second stage of labor in 52 women recruited at one North American hospital. Recordings were begun after documentation of full cervical dilatation and descent of the fetal head to +2 station (on a -3/+3 scale). Each woman acted as her own control, received epidural anesthesia, and was alert and responsive throughout the study. Pushing (closed glottis technique) was performed in a standardized fashion. Multivariate analysis with linear regression was applied to identify significant associations between maternal, fetal, or labor characteristics as the independent variables and the percent increase in IP consequent to active pushing as the dependent variable. Women in labor increase their IP 62% by actively pushing with a contraction during the second stage. A scattergram of the individual percent increase above the baseline IP integral revealed that for some women, pushing more readily increased their IP than it did for others (range, 0% to 192%). The percent increase was best calculated by a linear combination of myometrial thickness, estimated fetal weight, the maternal body mass index, and the obstetric need for labor augmentation (P =.007, r = 0.52, power = 0.975). A 66% change in IP provided the best separation between

No time for the gym? Housework and other non-labor market time use patterns are associated with meeting physical activity recommendations among adults in full-time, sedentary jobs.

PubMed

Smith, Lindsey P; Ng, Shu Wen; Popkin, Barry M

2014-11-01

Physical activity and inactivity have distinct cardio-metabolic consequences, suggesting that combinations of activities can impact health above and beyond the effects of a single activity. However, little work has examined patterns of non-labor market time activity in the US population, particularly among full-time employees in sedentary occupations, who are at increased risk of adverse health consequences associated with a sedentary lifestyle. Identification of these patterns, and how they are related to total physical activity levels, is important for developing effective, attainable physical activity recommendations among sedentary employees, who typically have less time available for exercise. This is especially the case for low-income employees who face the highest time and financial barriers to achieving physical activity goals. This study uses cluster analysis to examine patterns of non-labor market time use among full-time (≥40 h/week) employed adults in sedentary occupations (<3 MET-h) on working days in the American Time Use Study. We then examine whether these patterns are associated with higher likelihood of meeting physical activity recommendations and higher overall physical activity (MET-h). We find that non-labor market time use patterns include those characterized by screen activities, housework, caregiving, sedentary leisure, and exercise. For both genders, the screen pattern was the most common and increased from 2003 to 2012, while the exercise pattern was infrequent and consistent across time. Screen, sedentary leisure, and community patterns were associated with lower likelihoods of meeting physical activity recommendations, suggesting that interventions targeting screen time may miss opportunities to improve physical activity among similarly sedentary groups. Alternately, non-labor market time use patterns characterized by housework and caregiving represented feasible avenues for increasing overall physical activity levels, especially for

Fifty years of population growth and absorption of labor in Brazil: from 1950 to 2000.

PubMed

Paiva, P D

1997-01-01

For a long time, the Brazilian population has grown at a relatively high rate, and only recently has the process of demographic transition intensified in the country. While the associated decline in fertility could result in a future decline in the size of the working-age population, it could also lead to an increase in female participation in the labor market. Brazil's economy is performing well, with gross domestic product (GDP) growing at an average annual rate of 7.1% during 1947-80. Marked growth in industrial employment opportunities has accompanied this growth in GDP. The size of the informal sector, however, has not decreased in similar proportion, while the 1981-83 economic crisis caused urban employment levels to drop, especially in industry and construction. Moreover, the level of rural-urban migration has increased and the agricultural employment index has fallen. The author evaluates past growth trends of the Economically Active Population (EAP) and of employment in Brazil, and assesses the potential growth of the labor force until the year 2000.

Single cell active force generation under dynamic loading - Part I: AFM experiments.

Weafer, P P; Reynolds, N H; Jarvis, S P; McGarry, J P

2015-11-01

A novel series of experiments are performed on single cells using a bespoke AFM system where the response of cells to dynamic loading at physiologically relevant frequencies is uncovered. Measured forces for the untreated cells are dramatically different to cytochalasin-D (cyto-D) treated cells, indicating that the contractile actin cytoskeleton plays a critical role in the response of cells to dynamic loading. Following a change in applied strain magnitude, while maintaining a constant applied strain rate, the compression force for contractile cells recovers to 88.9±7.8% of the steady state force. In contrast, cyto-D cell compression forces recover to only 38.0±6.7% of the steady state force. Additionally, untreated cells exhibit strongly negative (pulling) forces during unloading half-cycles when the probe is retracted. In comparison, negligible pulling forces are measured for cyto-D cells during probe retraction. The current study demonstrates that active contractile forces, generated by actin-myosin cross-bridge cycling, dominate the response of single cells to dynamic loading. Such active force generation is shown to be independent of applied strain magnitude. Passive forces generated by the applied deformation are shown to be of secondary importance, exhibiting a high dependence on applied strain magnitude, in contrast to the active forces in untreated cells. A novel series of experiments are performed on single cells using a bespoke AFM system where the response of cells to dynamic loading at physiologically relevant frequencies is uncovered. Contractile cells, which contain the active force generation machinery of the actin cytoskeleton, are shown to be insensitive to applied strain magnitude, exhibiting high resistance to dynamic compression and stretching. Such trends are not observed for cells in which the actin cytoskeleton has been chemically disrupted. These biomechanical insights have not been previously reported.

Traction force dynamics predict gap formation in activated endothelium

Valent, Erik T.; Nieuw Amerongen, Geerten P. van; Hinsbergh, Victor W.M. van

In many pathological conditions the endothelium becomes activated and dysfunctional, resulting in hyperpermeability and plasma leakage. No specific therapies are available yet to control endothelial barrier function, which is regulated by inter-endothelial junctions and the generation of acto-myosin-based contractile forces in the context of cell-cell and cell-matrix interactions. However, the spatiotemporal distribution and stimulus-induced reorganization of these integral forces remain largely unknown. Traction force microscopy of human endothelial monolayers was used to visualize contractile forces in resting cells and during thrombin-induced hyperpermeability. Simultaneously, information about endothelial monolayer integrity, adherens junctions and cytoskeletal proteins (F-actin) were captured. This revealed a heterogeneousmore » distribution of traction forces, with nuclear areas showing lower and cell-cell junctions higher traction forces than the whole-monolayer average. Moreover, junctional forces were asymmetrically distributed among neighboring cells. Force vector orientation analysis showed a good correlation with the alignment of F-actin and revealed contractile forces in newly formed filopodia and lamellipodia-like protrusions within the monolayer. Finally, unstable areas, showing high force fluctuations within the monolayer were prone to form inter-endothelial gaps upon stimulation with thrombin. To conclude, contractile traction forces are heterogeneously distributed within endothelial monolayers and force instability, rather than force magnitude, predicts the stimulus-induced formation of intercellular gaps. - Highlights: • Endothelial monolayers exert dynamic- and heterogeneous traction forces. • High traction forces correlate with junctional areas and the F-actin cytoskeleton. • Newly formed inter-endothelial gaps are characterized by opposing traction forces. • Force stability is a key feature controlling endothelial permeability.« less
