Proportion Of Workers Research Articles

The Class Ceiling in Politics

Prior studies have documented that working-class individuals rarely become parliamentarians. We know less about when in the career pipeline to parliament workers disappear, and why. We study these questions using detailed data on the universe of Swedish politicians’ careers over a 50-year period. We find roughly equal-sized declines in the proportion of workers on various rungs of the political career ladder ranging from local to national office. We reject the potential explanations that workers lack political ambition, public service motivation, honesty, or voter support. And while workers’ average high school grades and cognitive test scores are lower, this cannot explain their large promotion disadvantage, a situation that we label a class ceiling. Organizational ties to blue-collar unions help workers advance, but only to lower-level positions in left-leaning parties. We conclude that efforts to improve workers’ numerical representation should apply throughout the career ladder and focus on intra-party processes.

Exposure to fine particulate matter in the New York City subway system during home-work commute.

The New York City (NYC) subway system accommodates 5.5 million daily commuters, and the environment within the subway is known to have high concentrations of fine particulate matter (PM2.5) pollution. Naturally, subway air pollution varies among individuals according to their mobility patterns, introducing the possibility of inequality in PM2.5 exposure. This study aims to evaluate individual and community-level exposure to subway PM2.5. We simulated the intracity home-to-work trip patterns using the Longitudinal Employer-Household Dynamics (LEHD) records of 3.1 million working commuters across 34,169 census blocks in four boroughs (Manhattan, Brooklyn, Queens, and the Bronx) of NYC. We incorporated the on-platform and on-train measured PM2.5 concentration data for the entire subway system. The mean underground platform concentration in the city was 139 μg/m3 with a standard deviation of 25 μg/m3, while the on-train concentration when underground was 99 μg/m3 with a standard deviation of 21 μg/m3. Using a network model, we determined the exposure of individual commuters during their daily home-work trips. We quantified the mean per capita exposure at the census block level by considering the proportion of workers within the blocks who rely on the subway for their work commute. Results indicate statistically significant weak positive correlation between elevated subway PM2.5 exposure and economically disadvantaged and racial minority groups.

Market concentration and productivity: evidence from the UK

AbstractWe measure product market concentration and business dynamism in the UK from 1997 to 2020 and study the relationship with productivity. Our results show that concentration in the UK is increasing among narrow industries on average, but for a broad market definition, concentration and business dynamism are stable. We find a negative relationship between concentration and productivity for the average firm, but a positive relationship for the average worker. This occurs because higher industry concentration is associated with better allocative efficiency, measured by the proportion of workers in higher‐productivity firms.

Transportation upgrades and structural transformation in the labor market: Evidence from a road improvement project in benin

How do transportation upgrades affect structural transformation in the labor market in developing countries? We focus on a specific case, Benin’s Djougou-N’dali Road Improvement Project conducted between 2004 and 2010, and estimate its effects on changes in the composition of workers by sector. Our difference-in-differences estimates suggest evidence of structural transformation in the labor market: the road improvement project leads to a relative increase in the proportion of workers in the industrial sector by 3.9 percentage points, representing a 30-percent increase. This is accompanied by a sharp decrease in the proportion of agricultural workers and an overall insignificant decrease in the proportion of service workers. These labor market effects are spatially heterogeneous: changes in agricultural workers and service workers are significant only in rural and urban areas, respectively, while both two types of areas see an increase in the proportion of industrial workers. Besides, these effects are significant only for female workers. Our findings present direct labor market effects of transportation upgrades through job switches across sectors, while other labor market mechanisms cannot explain structural transformation.

The Worker Flow at the Hive Entrance Predicts When Nest Cleaning is Intensified in Stingless Bees

Waste produced by living organisms is commonly disposed of as a prophylactic measure to avoid the spread of diseases and parasite infestation. For social insects, a proportion of workers is allocated to dispose the waste material outside the colony’s nest. However, most nests of social insects have a single entrance, where a high flow of individuals may create congestion, potentially compromising normal foraging activities and colony growth/health. Here, we investigated how two species of stingless bees (Tetragonisca fiebrigi and Plebeia droryana) deal with waste disposal and regular foraging activities, and the impacts of these activities on traffic flow at nest entrances. First, we compared the average traffic of bees assigned to waste removal activities. Following this, we investigated probabilities for waste removal as bee traffic increases. Then, we estimated a cutoff value to predict the likelihood that waste removal activities will be intensified over foraging trips. We found that, on average, the number of bees performing waste removal activities was lower than those undertaking foraging trips for both species. In addition, we observed that as overall bee traffic increases, the number of workers engaged in waste removal reduces or even ceases. Our models indicate that bee traffic of approximately 15 individuals/time is a cutoff score, below which, colonies invest in waste removal and above which, foraging trips are increased. It suggests that both species use the entrances of their colonies in an optimized way by adjusting which tasks should be intensified as the traffic of individuals increases.

Employment of Graduates in the Fields of Teacher Education and Education Science in Vietnam

Using data from the Labour Force Survey in 2018, 2019, and 2020, this paper is the first to analyze the employment issues of workers with university degrees in the fields of teacher education and education science in Vietnam. The results show that about 90% of the workers employed in the public sector and about 85% doing the jobs matched their field of study. However, the proportion of workers with matched jobs is much lower for those without social insurance and without a formal labor contract. The percentage of workers having social insurance and formal labor contracts is higher for those with mismatched jobs (about 98%) than for those with matched jobs (about 90%). The results of probit regression reveal that age and job sectors have a significant impact on the probability of workers having social insurance and formal labor contracts, while job mismatch has a negligible effect on the probability of workers having formal labor contracts.

THE CONSEQUENCES OF RECEIVING SOCIAL INSURANCE ONCE IN VIETNAM

Objective: Social insurance policies have played a crucial role as a cornerstone in the social security system, contributing positively to social stability and the realization of goals for a prosperous, strong, fair, democratic, and civilized society. The current legal framework on social insurance in Vietnam stipulates provisions to ensure the rights of workers in all cases, including regulations regarding one-time social insurance cases. Although the significance of receiving one-time social insurance aligns with the legal provisions for each case, the lack of understanding among workers regarding the significance of social insurance policies or their deliberate acceptance of one-time social insurance can have unpredictable consequences for society, the social insurance system, and the workers themselves... The study builds on the situation of receiving social insurance in Vietnam and makes a case study of consequences for once workers receive social insurance suggesting solutions to mitigate the situation. Method: The study is based on a method to collect secondary data on the status of social insurance once received in Vietnam through data channels. This data is presented and analyzed by the descriptive statistical method (mainly in the form of tables and charts) that will see the situation for receiving social insurance once in Vietnam over time. In order to conduct the research, the method applied in this article is a qualitative method including: The systematic approach to the research materials, legal regulations related to the research; The integrated analysis method is used to analyze and synthesize the situation of receiving social insurance once in Vietnam; The objective methodology is used by the author to argue, the views of the individual, along with the combination of perspectives of other studies of nature to make a broad consensus about a particular problem. Results: The results of the study show that although social insurance policies were established to protect workers from income risk, they can lead a stable future life. Rules on one-off social insurance regimes can help resolve many special cases of workers. However, research shows that the number of people who choose to receive social insurance in Vietnam in the period of 2014-2023 has increased greatly. The increase of the number of people who receive social insurance once means the increase in the number of people leaving the system, making it difficult to achieve the goal of universal social insurance coverage in the spirit of resolution No. 28-NQ/TW of the XII Central Committee. Actual data suggest that on average 1 new person is entering social insurance, there is 1 old person leaving the system. The number of people withdrawn the following year was always higher than the previous year with an average annual increase of about 10%. The proportion of workers that have returned from social insurance benefits to continue their low participation in social insurance. In the period of 2016-2022, the country had more than 4.8 million workers requesting and resolving social insurance once. After receiving social insurance coverage once, approximately 1.3 million people returned to continue the social insurance penetration. Thus, the proportion of workers who have been remarried to social insurance benefits is 26%, and the remaining 74% of those who have received social insurance benefits once, corresponding to about 3.5 million who do not return to social insurance contributions, meaning that they are not guaranteed short-term benefits in the process of continuing labor such as sickness, maternity, occupational accidents, unemployment and long-term retirement. Conclusion: Receiving one-time social insurance benefits of workers will have some consequences for the social insurance system, for Society and Workers in the current context of Vietnam population aging trends lead to the number of people who do not have a monthly pension in Vietnam accounting for a large proportion of approximately 10 million people, this shows that the lack of sustainability of the Social Security system in general creates pressure for the community and the workers themselves will not be protected from the immediate benefits and long-term social insurance system.

Dynamics of Information Flow and Task Allocation of Social Insect Colonies: Impacts of Spatial Interactions and Task Switching.

Models of social interaction dynamics have been powerful tools for understanding the efficiency of information spread and the robustness of task allocation in social insect colonies. How workers spatially distribute within the colony, or spatial heterogeneity degree (SHD), plays a vital role in contact dynamics, influencing information spread and task allocation. We used agent-based models to explore factors affecting spatial heterogeneity and information flow, including the number of task groups, variation in spatial arrangements, and levels of task switching, to study: (1) the impact of multiple task groups on SHD, contact dynamics, and information spread, and (2) the impact of task switching on SHD and contact dynamics. Both models show a strong linear relationship between the dynamics of SHD and contact dynamics, which exists for different initial conditions. The multiple-task-group model without task switching reveals the impacts of the number and spatial arrangements of task locations on information transmission. The task-switching model allows task-switching with a probability through contact between individuals. The model indicates that the task-switching mechanism enables a dynamical state of task-related spatial fidelity at the individual level. This spatial fidelity can assist the colony in redistributing their workforce, with consequent effects on the dynamics of spatial heterogeneity degree. The spatial fidelity of a task group is the proportion of workers who perform that task and have preferential walking styles toward their task location. Our analysis shows that the task switching rate between two tasks is an exponentially decreasing function of the spatial fidelity and contact rate. Higher spatial fidelity leads to more agents aggregating to task location, reducing contact between groups, thus making task switching more difficult. Our results provide important insights into the mechanisms that generate spatial heterogeneity and deepen our understanding of how spatial heterogeneity impacts task allocation, social interaction, and information spread.

Minimum wage and self-employed business owners: Evidence from South Korea

This study examines the influences of minimum wage on self-employment exits, using recent changes in the minimum wage level in South Korea. Using the cross-industry variation on the impact of the minimum wage—the proportion of workers whose wages are below the minimum wage in the upcoming year—combined with individual longitudinal data, I estimate the model of self-employment exits. Overall, the estimates show that the minimum wage hike has no significant impact on self-employed workers. However, it increases the likelihood of the business closing for the self-employed who hire employees. The results imply that a ten percent increase in the minimum wage raises the exit probability by 2.6 percentage points, which is 30.9 % of the average exit rate for those with employees. Moreover, the exits are significantly associated with the transition to non-employment.

Temporal Variability in Weaver Ant Oecophylla longinoda Latreille (Hymenoptera: Formicidae) Nest Characteristics in Selected Host Plants

Weaver ants (Oecophylla smaragdina and O. longinoda) are famous for their impressive nest constructions where they weave together living leaves on their host plants. Also, they are known to protect tropical tree crops against insect pests and are thus being utilized for biological control. To optimize their use, nest numbers have been used to track weaver ant abundances in plantation, assuming the number of nests reflects ant numbers. In this study we compared nest size, the density of ants and the proportion of workers in nests between three host plants (cashew, citrus and mango) and between two seasons (rainy and dry). Nest size, ant density and worker proportion all differed between host species, whereas only nest size and worker proportion showed seasonal differences and only on mango and citrus, respectively. On hosts with smaller nests (in increasing size order: cashew, citrus mango), ant densities in the nests were higher, and the proportion of workers in the nests seemed to increase during seasons where food production on host trees decreased, or on hosts where more trophobionts were cultured inside nests. These results have implications for the development of methods used to estimate ant numbers and they raise interesting questions about the function of weaver ant nests.

Gender role attitudes and the gender wage gap: evidence from China

This study explores the influence of gender role attitudes on the emergence of the gender wage gap in China, using the 2014, 2016, and 2018 data from the China Family Panel Studies and decomposition methods. Empirical results reveal that gender role attitudes significantly affect the gender wage gap in China and that the negative effect of inegalitarian gender role attitudes on wages is greater for women than for men. Both gender differences in the proportion of workers with inegalitarian gender role attitudes (endowment effect) and gender disparity in return to the gender role attitudes (return effect) contribute to the gender wage gap. Notably, the return effect outweighs the endowment effect. Furthermore, the effect of gender role attitudes on the formation of gender wage gaps differs across heterogeneous groups: the return effect is larger for urban workers or middle-aged and older generations compared to their rural counterparts or younger generations.

PENGARUH AKSESIBILITAS INTERNET TERHADAP LUARAN PASAR KERJA DI INDONESIA

After the Covid-19 pandemic, internet usage has increased dramatically. However, the impact of internet accessibility on the job market is still a circle in academic circles. There are those who argue that internet accessibility can improve labor market performance by reducing information distortions and increasing workers' skills. However, there are also those who argue that internet accessibility can hamper labor market performance due to a skills bias, where workers who are less skilled with routine tasks tend to be left out in the digitalization era. Therefore, this study aims to evaluate the extent to which internet accessibility influences the labor market in Indonesia using the Fixed Effect Model (FEM) method and Central Bureau of Statistics (BPS) data for 2010-2020. The results show that in general, the internet tends to improve the performance of the labor market in Indonesia with a positive effect on wage rates and the proportion of workers in the formal sector, and a negative effect on the Open Unemployment Rate (TPT). This study suggests that the internet can increase productivity and income as well as facilitate access to information on the labor market in Indonesia.

Time trends in the prevalence of depressive disorder symptoms in the Danish workforce, 2012 to 2018

Abstract Background Over the last decade, and well-before the COVID-19 pandemic, the prevalence of mental health problems has increased in many European countries, particularly in youth, raising public health concerns. Yet, there has been little focus on the mental health status of the working population, and it is unknown if the proportion of workers with impaired mental health is growing as well. In this paper, we report change in the prevalence of depressive disorder in a large nationwide sample of the Danish workforce (N = 76,802) from 2012 to 2018. Methods We used data from the Work Environment and Health in Denmark study, a bi-annual nationwide survey on working conditions and health. We measured depressive symptoms using the Major Depression Inventory and defined prevalence of depressive disorder by a score ≥21, in accordance with previous clinical validation studies. Using a log-binomial regression model, we estimated change in prevalence of depressive disorders from 2012 to 2018 with 95% confidence intervals (95% CI). Results From 2012 to 2018, the prevalence of depressive disorder increased from 7.0% (95% CI: 6.7-7.4) to 9.4% (9.0-9.9) corresponding to an adjusted increase of 36.1% (27.4-45.4) over the 6-year period. We observed a statistically significant increase in the prevalence in every wave, from 2012 to 2014 (adjusted change in prevalence: 10.8%, 3.2-18.9), from 2014 to 2016 (8.6%, 1.3-16.4)), and from 2016 to 2018 (13.1%, 6.0-20.7)). The increase occurred in both sexes, all age groups and for all types of occupational status, but was more pronounced among women, younger workers and workers of low occupational status. Conclusions In a large nationwide sample of the Danish workforce, we observed an increasing prevalence of depressive disorder from 2012 to 2018. The results indicate that the general trend towards increased levels of mental health problems also encompasses the workforce and underlines the need for public health action. Key messages • The prevalence of depressive disorder in the Danish workforce increased considerably from 2012 to 2018. • The increase in prevalence of depressive disorder was observed in all groups, but was particularly pronounced for women, younger workers and basic-skilled workers.

Multi-drug-resistant tuberculosis in COVID-19 pandemic period, Dushanbe

Aim. To evaluate the shifts in demographic, clinical, and epidemiological characteristics of patients with multidrugresistant tuberculosis (MDR TB) amidst the COVID-19 pandemic.Materials and Methods. A cross-sectional study was conducted on patients with MDR TB registered in Dushanbe, before (2017-2019) and during the COVID-19 pandemic (2020-2021).Results. The average age of patients prior to the COVID-19 pandemic was 36.5±16.9 years (1.7-79.4), whereas during the COVID-19 period, it was 34.4±17 years (2.9-80.2). The pandemic era witnessed a statistically significant rise in the proportion of workers among MDR TB patients compared to the unemployed (OR = 1.4; 95% CI 1.02-1.91; p = 0.05). Furthermore, an increase was observed in the proportion of patients with lung destruction in both newly diagnosed (OR 3.4; 95% CI 1.99–5.87; p&lt;0.001) and previously treated patients (OR 4.2; 95% CI 1.38–12.99; p =0.002). There was also an increase in extrapulmonary tuberculosis registration (OR=1.7; 95% CI 1.34-2.22; p&lt;0.001), indicating an unfavorable epidemiological situation in terms of MDR-TB. However, there were no statistically significant changes in the registration of concomitant diseases.Conclusion. We recommend the improvement of TB infection prevention and control measures at all levels, as well as the enhancement of early detection of TB and MDR TB patients by primary health care workers.

Analyse du profil des salariés déclarés inaptes au poste de travail : quelle place pour les facteurs sociétaux ou extra-professionnels et quelles conséquences sur l'emploi ?

IntroductionProfessional career can be modified by health problems. Professional impairment, certified by an occupational health physician, can be followed by a redeployment or occupational disintegration. ObjectivesTo describe the profiles of workers declared unfit for their workplace and the profiles of those who have no remaining work capacity (RWC). MethodsThe workers followed by an inter-enterprise occupational health service composed of 20 occupational physicians. The characteristics of workers declared unfit for work were extracted from the medical files: age, gender, activity sector (Naf), socioprofessional category (PCS), pathology leading to professional impairment (CIM10), status of obligation to employ disabled workers (BOETH). Factors associated with unfitness to work due to no remaining work capacity (RWC) were identified by logistic regression models. ResultsIn 2019, 82678 workers in France were followed by the SPSTI and 554 (0.67%), of whom 162 had no RWC, were declared unfit to work by an occupational health physician. Professional impairment rates were highest for women and workers > 55 years old. Psychological (29%) and rheumatic (50%) pathologies were the most frequent causes of professional impairment. BOETH status was identified among 63%. Age > 45 and psychological pathology were significantly associated with absent RWC, whereas gender, activity sector and PCS were not. DiscussionNo comprehensive public administration records of professional impairment exist in France. While past studies have described the profiles of workers who were unfit for their workplace, none have characterized those without RWC, who are high risk of precarity. ConclusionsPsychological pathologies generate the most professional impairment in persons without RWC. Prevention of these pathologies is essential. While rheumatic disease is the first cause of professional impairment, the proportion of workers with these diseases who have no remaining work capacity is relatively low; this may be due to the efforts made to facilitate their return to work.

Dynamic assessment of the situation with the working conditions of employees of the main types of economic activity and mining of the Russian Federation and the Republic of Bashkortostan

The priority task of the state policy is to preserve the labor activity of the population by ensuring safe working conditions, which, according to official reports, are not considered as such in most enterprises of the country, including in mining operations. The goal is monitor the state of working conditions of workers in the extraction of minerals in the Republic of Bashkortostan, comparing them with similar data for the Russian Federation and for the main types of economic activity. According to Rosstat data, at mining enterprises in the Russian Federation, the share of the number of employees employed in jobs with harmful and (or) dangerous working conditions increased by 9.8 % compared to 2011, in the Republic of Bashkortostan — by 13, 4 %, amounting to 55.1 % and 45.0 % of the total number of employees in the industry by 2020, respectively. For comparison with data on the main types of economic activity in Russia, the indicators increased by 6.8 %, in the republic — by 4 %. and noise. In addition, there has been a significant increase in the proportion of people working in contact with vibration and chemical factors in excess of the allowable values in the region. Studies show unresolved problems in the production of minerals, causing an increase in the proportion of workers with harmful working conditions, including certain factors of production, which will undoubtedly be reflected in the indicators of occupational and production-related morbidity, industrial injuries, including severe outcomes.

Excess risk of SARS‐CoV‐2 infection among in‐person nonhealthcare workers in six states, September 2020–June 2021

While the occupational risk of severe acute respiratory syndromecoronavirus 2 (SARS-CoV-2) infection for healthcare personnel in the United States has been relatively well characterized, less information is available on the occupational risk for workers employed in other settings. Even fewer studies have attempted to compare risks across occupations and industries. Using differential proportionate distribution as an approximation, we evaluated excess risk of SARS-CoV-2 infection by occupation and industry among non-healthcare workers in six states. We analyzed data on occupation and industry of employment from a six-state callback survey of adult non-healthcare workers with confirmed SARS-CoV-2 infection and population-based reference data on employment patterns, adjusted for the effect of telework, from the U.S. Bureau of Labor Statistics. We estimated the differential proportionate distribution of SARS-CoV-2 infection by occupation and industry using the proportionate morbidity ratio (PMR). Among a sample of 1111 workers with confirmed SARS-CoV-2 infection, significantly higher-than-expected proportions of workers were employed in service occupations (PMR 1.3, 99% confidence interval [CI] 1.1-1.5) and in the transportation and utilities (PMR 1.4, 99% CI 1.1-1.8) and leisure and hospitality industries (PMR 1.5, 99% CI 1.2-1.9). We found evidence of significant differences in the proportionate distribution of SARS-CoV-2 infection by occupation and industry among respondents in a multistate, population-based survey, highlighting the excess risk of SARS-CoV-2 infection borne by some worker populations, particularly those whose jobs require frequent or prolonged close contact with other people.
