The gender wage gap in the public and private sectors in Bangladesh

The gender wage gap is well studied in developed countries; however, recently it has generated much interest in developing countries. This thesis addresses three issues regarding the gender wage gap in Bangladesh. Firstly, it explores the wage determinants for formal public and private sector employees in Bangladesh and examines the gender pay gap. This is the first time different decomposition methods have been used to compare the sources of the gender wage gap as well as any potential discrimination effect in the formal sector of the Bangladeshi labour market. These decomposition methods are: the original Oaxaca (1973) and Blinder (1973) decomposition methods, the Neumark (1988), Cotton (1988), and Reimers (1983) methods, and the extended Oaxaca method including both the employment selection and the double selection correction in the wage equation. In addition to mentioned methods, to quantify the gender wage gap in monetary terms, a recently developed ‘simulated change’ approach by Olsen and Walby (2004) is also applied for the first time to the Bangladeshi data. By using the Labour Force Survey 2005-06, BBS (LFS 2005-06) data results show formal sector female employees earn about 32.1 per cent less than their male counterparts. Without considering the selection correction, a large range of human capital, demographic and labour market related variables are explained less than half of the total gender wage gap (21 to 46 per cent of the total wage gap) and the major part of the wage gap is unexplained (54 to 79 per cent of the total wage gap). This could partly be attributed to discrimination. Using the double selection correction method, the decomposition results changed where a small part of the wage gap was explained by the measured characteristics (only nine per cent of the total wage gap) and a major part is attributed to the discrimination and selection effect. The selection effect also reveals that exclusion of the double selection correction might lead to an overestimation of the gender wage gap in the formal sector of Bangladesh. In addition, results based on the Olsen and Walby (2004) simulation method show that, if the other characteristics of male and female employees were similar, ‘being female’ is sufficient, to generate significantly lower wages than males in the formal sector. If females in the workplace are treated as males, without considering any other endowment increases, females could increase their earnings by 4095.3 Taka1 per year. Results also indicate that not only endowment differences in human capital and work experience related variables were important, but discrimination appears to play a significant role in the total wage gap throughout the formal sector of the Bangladeshi labour market. Secondly, the study investigates whether public sector employees enjoyed a wage premium or not, compared to the private sector and whether the gender wage gap is greater in the public sector. In addition, the research considered whether there was an impact from the inclusion of the different selection correction terms in the wage equation. In Bangladesh, public sector employees have, on average, a 60 per cent wage premium over the private sector. Using both the original Oaxaca and the extended Oaxaca methods, where selection effect is partly captured by both explained and unexplained components, and using the public sector wage structure as the basis of the non-discriminatory wage structure, these methods revealed a considerably larger portion of explained (72 - 93 per cent of the total wage gap) and a smaller portion of unexplained part of the wage gap. However, if the selection correction is considered as another component of the decomposition outcome then the major portion of the total public and private sectors wage gap is justified (explained) by the effect of the selection correction and unexplained factors. Furthermore, a large part of the wage premium exists in favour of public sector female employees compared to males and the gender wage gap is lower in the public sector than the private sector. Finally, this study compares the gender wage gap of five different occupations. The gender wage gap is associated with labour market rigidities where one of the important factors is occupational segregation where females are disproportionately distributed in occupations resulting in lower earnings. The largest gender wage gap was found in agriculture, forestry, fisheries, production and transport labour jobs (56.4 per cent) and the lowest in the professional, technical administrative and managerial jobs (22.1 per cent). Substantial differences are found in the size of the endowment gap across occupations and larger variations occurred in the adjusted wage gap which varied from 21.4 per cent in sales and service occupations, to 100 per cent in professional and technical jobs (the highest). This too can be partly explained by discrimination. A reduction in the gender wage gap is expected not only to increase national income, but also to reduce poverty and lead to better outcomes for future generations. National policy should aim to reduce the gender wage gap and achieve gender wage equality in the formal sector; for example through a targeted program to remove the gender differences in education and to reduce the skill difference, with a better child care policy to encourage labour force retention and increased labour market experience for female employees, with anti-discriminatory policies and the enforcement of existing antidiscrimination policies, and a more equal distribution of males and females across occupations.

Race and sex effects on the association between muscle strength, soft tissue, and bone mineral density in healthy elders: The Health, Aging, and Body Composition Study

Two factors generally reported to influence bone density are body composition and muscle strength. However, it is unclear if these relationships are consistent across race and sex, especially in older persons. If differences do exist by race and/or sex, then strategies to maintain bone mass or minimize bone loss in older adults may need to be modified accordingly. Therefore, we examined the independent effects of bone mineral-free lean mass (LM), fat mass (FM), and muscle strength on regional and whole body bone mineral density (BMD) in a cohort of 2619 well-functioning older adults participating in the Health, Aging, and Body Composition (Health ABC) Study with complete measures. Participants included 738 white women, 599 black women, 827 white men, and 455 black men aged 70-79 years. BMD (g/cm(2)) of the femoral neck, whole body, upper and lower limb, and whole body and upper limb bone mineral-free LM and FM was assessed by dual-energy X-ray absorptiometry (DXA). Handgrip strength and knee extensor torque were determined by dynamometry. In analyses stratified by race and sex and adjusted for a number of confounders, LM was a significant (p < 0.001) determinant of BMD, except in white women for the lower limb and whole body. In women, FM also was an independent contributor to BMD at the femoral neck, and both PM and muscle strength contributed to limb BMD. The following were the respective Beta-weights (regression coefficients for standardized data, Std beta) and percent difference in BMD per unit (7.5 kg) LM: femoral neck, 0.202-0.386 and 4.7-6.9 %; lower limb,.0.209-0.357 and 2.9-3.5%; whole body, 0.239-0.484 and 3.0-4.7 %; and upper limb (unit = 0.5 kg), 0.231-0.407 and 3.1-3.4%. Adjusting for bone size (bone mineral apparent density [BMAD]) or body size BMD/height) diminished the importance of LM, and the contributory effect of FM became more pronounced. These results indicate that LM and FM were associated with bone mineral depending on the bone site and bone index used. Where differences did occur, they were primarily by sex not race. To preserve BMD, maintaining or increasing LM in the elderly would appear to be an appropriate strategy, regardless of race or sex.

Effects of sex hormonal levels and phases of the menstrual cycle in the processing of emotional faces

Several neuropsychiatry disorders have shown a sexual dimorphism in their incidence, symptom profile and therapeutic response. A better understanding of the impact of sex hormones in emotional processing sexual dimorphism could bring tight to this important clinical finding. Some studies have provided evidence of sex differences in the identification of emotional faces, however, results are inconsistent and such inconsistency could be related to the lack of experimental control of the sex hormone status of participants. More recently, a few studies evaluated the modulation of facial emotion recognition by the phase of the menstrual cycle and sex hormones, however, none of them directly compared these results with a group of men. We evaluated the accuracy of facial emotion recognition in 40 healthy volunteers. Eleven women were assigned to early follicular group, nine women to the ovulatory group and 10 women to luteal group, depending on the phase of menstrual cycle, and a group of 10 men were also evaluated. Estrogen, progesterone and testosterone levels were assessed. The performance of the groups in the identification of emotional faces varied depending on the emotion. Early follicular group were more accurate to perceive angry faces than all other groups. Sadness was more accurately recognized by early follicular group than by luteal group and regarding the recognition of fearful faces a trend to a better performance and a significantly higher accuracy was observed, respectively, in the early follicular group and in the ovulatory group, in comparison to men. In women, estrogen negatively correlated to the accuracy in perception of angry mate faces. Our results indicate sex hormones to be implicated in a sexual dimorphism in facial emotion recognition, and highlight the importance of estrogen specifically in the recognition of negative emotions such as sadness, anger and fear.

The endgame for national girls' schooling policies in Australia?

Gender equity: A framework for Australian schools is the most recent policy dealing with gender in schools at the national level in Australia. This paper provides a critical discourse analysis of the policy document, tracking two themes: 'the construction of gender', and 'equity: a discourse of education for all boys and girls'. Through this analysis the authors argue that the policy signals a substantial shift in focus-from girls and boys in relation to girls, to both girls and boys-within a framework of presumptive equality. It is also argued that the policy shuts down federal involvement in policy for girls' schooling. In the process, responsibility is devolved to the states and territories where, in many cases, gender equity programs will be struggled over at a local, school-based level. At the same time, however, spaces have been created which potentially enable new strategies for gender equity policies in Australian schools.

India's homosexual discrimination and health consequences

A large number of countries worldwide have legalized homosexual rights. But for 147 years, since when India was a British colony, Section 377 of the Indian Penal Code defines homosexuality as a crime, punishable by imprisonment. This outdated law violates the fundamental rights of homosexuals in India. Despite the fact that literature drawn from Hindu, Buddhist, Muslim, and modern fiction testify to the presence of same-sex love in various forms, homosexuality is still considered a taboo subject in India, by both the society and the government. In the present article, the continuation of the outdated colonial-era homosexuality law and its impact on the underprivileged homosexual society in India is discussed, as well as consequences to this group's health in relation to HIV infection.

Application of FTA and the perceived impact on employment policies: the case of nanotechnology in the Netherlands, Germany and Portugal

In this paper we will analyse the usage of FTA to support decision-making in employment policy relate to specific occupational groups. The examples can be better understood if one focus on the nanotechnology and its implications on some sectors (clothing, bio-medical engineering, micro-electronics). When this is done will be clear which occupations will engage a restructuring process (engineers, specialised technicians, qualified machine operators, quality controllers) and what policies are being designed to cope with it. This means toward which extend social partners have driven specific policies on these issues (focused in their sectors).

Differences in Nevirapine Biotransformation as a Factor for its Sex-Dependent Dimorphic Profile of Adverse Drug Reactions

OBJECTIVES: Nevirapine is widely used for the treatment of HIV-1 infection; however, its chronic use has been associated with severe liver and skin toxicity. Women are at increased risk for these toxic events, but the reasons for the sex-related differences are unclear. Disparities in the biotransformation of nevirapine and the generation of toxic metabolites between men and women might be the underlying cause. The present work aimed to explore sex differences in nevirapine biotransformation as a potential factor in nevirapine-induced toxicity. METHODS: All included subjects were adults who had been receiving 400 mg of nevirapine once daily for at least 1 month. Blood samples were collected and the levels of nevirapine and its phase I metabolites were quantified by HPLC. Anthropometric and clinical data, and nevirapine metabolite profiles, were assessed for sex-related differences. RESULTS: A total of 52 patients were included (63% were men). Body weight was lower in women (P = 0.028) and female sex was associated with higher alkaline phosphatase (P = 0.036) and lactate dehydrogenase (P = 0.037) levels. The plasma concentrations of nevirapine (P = 0.030) and the metabolite 3-hydroxy-nevirapine (P = 0.035), as well as the proportions of the metabolites 12-hydroxy-nevirapine (P = 0.037) and 3-hydroxy-nevirapine (P = 0.001), were higher in women, when adjusted for body weight. CONCLUSIONS: There was a sex-dependent variation in nevirapine biotransformation, particularly in the generation of the 12-hydroxy-nevirapine and 3-hydroxy-nevirapine metabolites. These data are consistent with the sex-dependent formation of toxic reactive metabolites, which may contribute to the sex-dependent dimorphic profile of nevirapine toxicity.

Sex difference and the role of leptin in the association between high-sensitivity C-reactive protein and adiposity in two different populations.

Elevated high-sensitivity C-reactive protein (hs-CRP) concentration is associated with an increased risk of cardiovascular disease but this association seems to be largely mediated via conventional cardiovascular risk factors. In particular, the association between hs-CRP and obesity has been extensively demonstrated and correlations are stronger in women than men. We used fractional polynomials-a method that allows flexible modeling of non linear relations-to investigate the dose/response mathematical relationship between hs-CRP and several indicators of adiposity in Caucasians (Switzerland) and Africans (Seychelles) surveyed in two population-based studies. This relationship was non-linear exhibiting a steeper slope for low levels of hs-CRP and a higher level in women. The observed sex difference in the relationship between hs-CRP and adiposity almost disappeared upon adjustment for leptin, suggesting that these sex differences might be partially mediated, by leptin. All these relationship were similar in Caucasians and Africans. This is the first report on a non-linear relation, stratified by gender, between hs-CRP and adiposity.

Testing kin selection with sex allocation data in eusocial hymenoptera

Sex allocation data in eusocial Hymenoptera (ants, bees and wasps) provide an excellent opportunity to assess the effectiveness of kin selection, because queens and workers differ in their relatedness to females and males. The first studies on sex allocation in eusocial Hymenoptera compared population sex investment ratios across species. Female-biased investment in monogyne (= with single-queen colonies) populations of ants suggested that workers manipulate sex allocation according to their higher relatedness to females than males (relatedness asymmetry). However, several factors may confound these comparisons across species. First, variation in relatedness asymmetry is typically associated with major changes in breeding system and life history that may also affect sex allocation. Secondly, the relative cost of females and males is difficult to estimate across sexually dimorphic taxa, such as ants. Thirdly, each species in the comparison may not represent an independent data point, because of phylogenetic relationships among species. Recently, stronger evidence that workers control sex allocation has been provided by intraspecific studies of sex ratio variation across colonies. In several species of eusocial Hymenoptera, colonies with high relatedness asymmetry produced mostly females, in contrast to colonies with low relatedness asymmetry which produced mostly males. Additional signs of worker control were found by investigating proximate mechanisms of sex ratio manipulation in ants and wasps. However, worker control is not always effective, and further manipulative experiments will be needed to disentangle the multiple evolutionary factors and processes affecting sex allocation in eusocial Hymenoptera.

Employment & Retirement Among the Over 55s - Conference Proceedings

The Conference provided the opportunity for delegates to focus attention on issues of employment and retirement among older Irish people, issues such as preferences for work or retirement and barriers to staying in or returning to the workplace. It also afforded the opportunity to look at initiatives at the European level as well as recent developments in Ireland in relation to age discrimination, pension provision and lifelong learning initiatives Download the Report here

Guía metodológica para la elaboración de planes de igualdad en entidades del Sistema Sanitario Público de Andalucía (SSPA)

Currently equality plans are an effective tool to incorporate equal opportunities in human resource management of both companies and public administrations. They are also the appropriate mechanism to detect possible disparities and gender gaps in employment. Configured as an ordered set of actions and measures taken after a diagnosis of the situation and help organizations to promote equal treatment and opportunities between women and men in the workplace, and help eliminate discrimination based on sex. In this regard, the Directorate General of Health Planning and Innovation of the Ministry of Health, intends to promote and facilitate the development and implementation of equality plans in institutions and centers of the Andalusian Public Health System. This has raised the production and dissemination of a methodological guide that supports the design of equality plans in unison to allow both the completion of the monitoring process as the development and practical implementation of those plans.

Between-year variation in population sex ratio increases with complexity of the breeding system in Hymenoptera.

While adaptive adjustment of sex ratio in the function of colony kin structure and food availability commonly occurs in social Hymenoptera, long-term studies have revealed substantial unexplained between-year variation in sex ratio at the population level. In order to identify factors that contribute to increased between-year variation in population sex ratio, we conducted a comparative analysis across 47 Hymenoptera species differing in their breeding system. We found that between-year variation in population sex ratio steadily increased as one moved from solitary species, to primitively eusocial species, to single-queen eusocial species, to multiple-queen eusocial species. Specifically, between-year variation in population sex ratio was low (6.6% of total possible variation) in solitary species, which is consistent with the view that in solitary species, sex ratio can vary only in response to fluctuations in ecological factors such as food availability. In contrast, we found significantly higher (19.5%) between-year variation in population sex ratio in multiple-queen eusocial species, which supports the view that in these species, sex ratio can also fluctuate in response to temporal changes in social factors such as queen number and queen-worker control over sex ratio, as well as factors influencing caste determination. The simultaneous adjustment of sex ratio in response to temporal fluctuations in ecological and social factors seems to preclude the existence of a single sex ratio optimum. The absence of such an optimum may reflect an additional cost associated with the evolution of complex breeding systems in Hymenoptera societies.

Within-population polymorphism of sex-determination systems in the common frog (Rana temporaria).

In sharp contrast with birds and mammals, the sex chromosomes of ectothermic vertebrates are often undifferentiated, for reasons that remain debated. A linkage map was recently published for Rana temporaria (Linnaeus, 1758) from Fennoscandia (Eastern European lineage), with a proposed sex-determining role for linkage group 2 (LG2). We analysed linkage patterns in lowland and highland populations from Switzerland (Western European lineage), with special focus on LG2. Sibship analyses showed large differences from the Fennoscandian map in terms of recombination rates and loci order, pointing to large-scale inversions or translocations. All linkage groups displayed extreme heterochiasmy (total map length was 12.2 cM in males, versus 869.8 cM in females). Sex determination was polymorphic within populations: a majority of families (with equal sex ratios) showed a strong correlation between offspring phenotypic sex and LG2 paternal haplotypes, whereas other families (some of which with female-biased sex ratios) did not show any correlation. The factors determining sex in the latter could not be identified. This coexistence of several sex-determination systems should induce frequent recombination of X and Y haplotypes, even in the absence of male recombination. Accordingly, we found no sex differences in allelic frequencies on LG2 markers among wild-caught male and female adults, except in one high-altitude population, where nonrecombinant Y haplotypes suggest sex to be entirely determined by LG2. Multifactorial sex determination certainly contributes to the lack of sex-chromosome differentiation in amphibians.

Sex-biased dispersal in a migratory bat: a characterization using sex-specific demographic parameters.

We studied the noctule bat (Nyctalus noctula), in which the mitochondrial F(ST) is about 10 times that revealed by nuclear markers, to address two questions. We first verified whether random dispersal of one sex is compatible with highly contrasted mitochondrial and nuclear population structures. Using computer simulations, we then assessed the power of multilocus population differentiation tests when the expected population structure departs only slightly from panmixia. Using an island model with sex-specific demographic parameters, we found that random male dispersal is consistent with the population structure observed in the noctule. However, other parameter combinations are also compatible with the data. We computed the minimum sex bias in dispersal (at least 69% of the dispersing individuals are males), a result that would not be available if we had used more classical population genetic models. The power of multilocus population differentiation tests was unexpectedly high, the tests being significant in almost 100% of the replicates, although the observed population structure infered from nuclear markers was extremely low (F(ST) = 0.6%).

Geographical and temporal body size variation in a reptile: roles of sex, ecology, phylogeny and ecology structured in phylogeny.

Geographical body size variation has long interested evolutionary biologists, and a range of mechanisms have been proposed to explain the observed patterns. It is considered to be more puzzling in ectotherms than in endotherms, and integrative approaches are necessary for testing non-exclusive alternative mechanisms. Using lacertid lizards as a model, we adopted an integrative approach, testing different hypotheses for both sexes while incorporating temporal, spatial, and phylogenetic autocorrelation at the individual level. We used data on the Spanish Sand Racer species group from a field survey to disentangle different sources of body size variation through environmental and individual genetic data, while accounting for temporal and spatial autocorrelation. A variation partitioning method was applied to separate independent and shared components of ecology and phylogeny, and estimated their significance. Then, we fed-back our models by controlling for relevant independent components. The pattern was consistent with the geographical Bergmann's cline and the experimental temperature-size rule: adults were larger at lower temperatures (and/or higher elevations). This result was confirmed with additional multi-year independent data-set derived from the literature. Variation partitioning showed no sex differences in phylogenetic inertia but showed sex differences in the independent component of ecology; primarily due to growth differences. Interestingly, only after controlling for independent components did primary productivity also emerge as an important predictor explaining size variation in both sexes. This study highlights the importance of integrating individual-based genetic information, relevant ecological parameters, and temporal and spatial autocorrelation in sex-specific models to detect potentially important hidden effects. Our individual-based approach devoted to extract and control for independent components was useful to reveal hidden effects linked with alternative non-exclusive hypothesis, such as those of primary productivity. Also, including measurement date allowed disentangling and controlling for short-term temporal autocorrelation reflecting sex-specific growth plasticity.
