Occupational status and organizations: Variation in occupational hierarchies across Swedish workplaces

A foundational claim in social stratification research is that occupational hierarchies are largely invariant across societies, a phenomenon known as the Treiman constant. However, recent research in social stratification has focused on the role of local social spaces in generating inequalities, casting doubt on the validity of the idea of a universally invariant occupational hierarchy. In this paper, we focus on organizations as a local space in which occupational hierarchies may vary. We ask three questions: (1) do occupational hierarchies vary across workplaces, (2) why do occupational hierarchies vary across workplaces, and (3) what can explain why some occupations move up or down the occupational hierarchy in specific workplace contexts? Using novel administrative data from Sweden we measure and model the correlation between a workplace’s occupational hierarchy and the national occupational hierarchy, finding substantial variation across workplaces in the matching of a given workplace’s hierarchy to the national hierarchy. We then develop a set of contextual and relational variables at the organizational level to potentially explain this variation, as well as to explain which occupations move up or down the workplace hierarchy. This paper points toward an important and novel empirical finding – variation across workplaces in occupational hierarchies – both confirming the power of the Treiman constant while opening up avenues to explore deviations from it. It also reveals the need to develop theories than can explain this workplace-level variation

Birth order and college major in Sweden

Previous research on birth order has consistently shown that later-borns have lower educational attainment than first-borns, however it is not known whether there are birth order patterns in college major. Given empirical evidence that parents disproportionately invest in first-born children, there are likely to be birth order patterns attributable to differences in both opportunities and preferences, related to ability, human capital specialization through parentchild transfers of knowledge, and personality. Birth order patterns in college major specialization may shed light on these explanatory mechanisms, and may also account for long-term birth order differences in educational and labour market outcomes. Using Swedish population register data and sibling fixed effects we find large birth order differences in university applications. First-borns are more likely to apply to, and graduate from, medicine and engineering programs at university, while later-borns are more likely to study journalism and business programs, and to attend art school. We also find that these birth order patterns are stronger in high SES families, and that differences in college major explain approximately half of the within-family birth order differences in long-term earnings. These results indicate that early life experiences and parental investment shapes sibling differences in ability, preferences, and ambitions even within the shared environment of the family

The effect of acute exercise on glycogen synthesis rate in obese subjects studied by 13C MRS

In obesity, insulin-stimulated glucose uptake in skeletal muscle is decreased. We investigated whether the stimulatory effect of acute exercise on glucose uptake and subsequent glycogen synthesis was normal. The study was performed on 18 healthy volunteers, 9 obese (BMI = 32.6 ± 1.2 kg/m2, mean ± SEM) and 9 lean (BMI = 22.0 ± 0.9 kg/m2), matched for age and gender. All participants underwent a euglycemic hyperinsulinemic clamp, showing reduced glucose uptake in the obese group (P = 0.01), during which they performed a short intense local exercise (single-legged toe lifting). Dynamic glucose incorporation into glycogen in the gastrocnemius muscle before and after exercise was assessed by 13C magnetic resonance spectroscopy combined with infusion of [1-13C]glucose. Blood flow was measured to investigate its potential contribution to glucose uptake. Before exercise, glycogen synthesis rate tended to be lower in obese subjects compared with lean (78 ± 14 vs. 132 ± 24 μmol/kg muscle/min; P = 0.07). Exercise induced highly significant rises in glycogen synthesis rates in both groups, but the increase in obese subjects was reduced compared with lean (112 ± 15 vs. 186 ± 27 μmol/kg muscle/min; P = 0.03), although the relative increase was similar (184 ± 35 vs. 202 ± 51%; P = 0.78). After exercise, blood flow increased equally in both groups, without a temporal relationship with the rate of glycogen synthesis. In conclusion, this study shows a stimulatory effect of a short bout of acute exercise on insulin-induced glycogen synthesis rate that is reduced in absolute values but similar in percentages in obese subjects. These results suggest a shared pathway between insulin- and exercise-induced glucose uptake and subsequent glycogen synthesis

Exercise training with dietary counselling increases mitochondrial chaperone expression in middle-aged subjects with impaired glucose tolerance

<p>Abstract</p> <p>Background</p> <p>Insulin resistance and diabetes are associated with increased oxidative stress and impairment of cellular defence systems. Our purpose was to investigate the interaction between glucose metabolism, antioxidative capacity and heat shock protein (HSP) defence in different skeletal muscle phenotypes among middle-aged obese subjects during a long-term exercise and dietary intervention. As a sub-study of the Finnish Diabetes Prevention Study (DPS), 22 persons with impaired glucose tolerance (IGT) taking part in the intervention volunteered to give samples from the <it>vastus lateralis </it>muscle. Subjects were divided into two sub-groups (IGTslow and IGTfast) on the basis of their baseline myosin heavy chain profile. Glucose metabolism, oxidative stress and HSP expressions were measured before and after the 2-year intervention.</p> <p>Results</p> <p>Exercise training, combined with dietary counselling, increased the expression of mitochondrial chaperones HSP60 and glucose-regulated protein 75 (GRP75) in the <it>vastus lateralis </it>muscle in the IGTslow group and that of HSP60 in the IGTfast group. In cytoplasmic chaperones HSP72 or HSP90 no changes took place. In the IGTslow group, a significant positive correlation between the increased muscle content of HSP60 and the oxygen radical absorbing capacity values and, in the IGTfast group, between the improved VO_2maxvalue and the increased protein expression of GRP75 were found. Serum uric acid concentrations decreased in both sub-groups and serum protein carbonyl concentrations decreased in the IGTfast group.</p> <p>Conclusion</p> <p>The 2-year intervention up-regulated mitochondrial HSP expressions in middle-aged subjects with impaired glucose tolerance. These improvements, however, were not correlated directly with enhanced glucose tolerance.</p

Does co-residence with grandparents reduce the negative association between sibship size and reading test scores? Evidence from 40 countries.

This paper investigates the effect of coresidence with grandparents in three-generation households on the nature and size of the association between sibship size and reading test scores. It also explores whether this interaction changes with the level of socioeconomic development of a society. We argue that coresidence in traditional three-generation households has a protective effect against resource dilution and thus decreases the magnitude of the negative association between family size and test scores. We also suggest that coresidence in more modern contexts magnifies the degree of this negative association, since modern families form three-generation households only when severely destabilized. We apply 3-level regression models to the PISA 2000 data to examine our hypotheses and use the Human Development Index as a measure of development. We find that the negative association between family size and test scores increases at higher levels of development and does so more strongly when students coreside with grandparents. We, however, find no context, in which coresidence would erase the negative consequences of having many brothers and sisters on one’s own school test scores. These findings hold even when controlling statistically for the effects of public expenditure on education, public social security expenditure, and crude divorce rate as well as for the interactions of these variables with sibship size.This paper investigates the effect of coresidence with grandparents in three-generation households on the nature and size of the association between sibship size and reading test scores.

Persistent nepotism in peer-review

In a replication of the high-profile contribution by Wenneras and Wold on grant peer-review, we investigate new applications processed by the medical research council in Sweden. Introducing a normalisation method for ranking applications that takes into account the differences between committees, we also use a normalisation of bibliometric measures by field. Finally, we perform a regression analysis with interaction effects. Our results indicate that female principal investigators (PIs) receive a bonus of 10% on scores, in relation to their male colleagues. However, male and female PIs having a reviewer affiliation collect an even higher bonus, approximately 15%. Nepotism seems to be a persistent problem in the Swedish grant peer review system.Erratum to paper on: 10.1007/s11192-020-03739-4Jointly published by Akadémiai Kiadó, Budapest and Springer, Dordrecht QC 20120207</p

Families, neighborhoods, and the future : The transition to adulthood of children of native and immigrant origin in Sweden

In this paper, we examine mechanisms that generate gaps in educational attainment and labor market outcomes between children of immigrants and children of native Swedes. Theoretical explanations of how social inequality between generations is (re)produced focus on a relative lack of resources within the family and/or in the broader social environment, particularly in neighborhoods and schools. In the empirical analyses we follow over time all individuals who completed compulsory school during the period 1990 -1995 and analyze what types of background factors have influenced their educational and labor market careers, which are measured for the year 2007. On the basis of our empirical results we conclude that the gaps between children of immigrants and children of native Swedes are mainly generated by differences in various forms of resources in the family of origin. The role of neighborhood segregation is less substantial. Moreover, our results indicate that the gaps in employment are larger than the corresponding gaps in educational attainment. When gainfully employed, children of immigrants born in Sweden follow roughly the same path as children from native families in contrast to children born abroad

Does the impact of parental death vary by parental socioeconomic status? A study of children's educational and occupational attainment

Objective: We examine whether parental death differentially affects educational and occupational attainment by the socioeconomic status of the parent who dies and the socioeconomic status of the surviving parent and extended kin. Background: An extensive literature has explored the main effect of parental death on offspring attainment, but few studies have examined socioeconomic differentials in the impact of parental death. Understanding the potential role of socioeconomic resources in compensating for disadvantage is important for understanding whether parental death, and disadvantageous events more generally, have an equalizing or exacerbating effect on socioeconomic differences in offspring socioeconomic attainment. Method: Using Swedish population register data on cohorts born 1973—1982 we examine grade point average at age 16, the transition from lower to upper-secondary education, the transition to tertiary education, overall educational attainment, and occupational status by age 30. We match families using antemortem parental socioeconomic trajectories. We also employ sibling fixed effects models. Results: We observe inconsistent results in our between-family regression analyses adjusting for observables. In sibling fixed effects models, we see zero results for moderation by parents’ occupations. Conclusion: We find little clear or convincing evidence that there are socioeconomic differentials in the impact of parental death in Sweden.​ Implications: The Swedish welfare state may reduce socioeconomic differentials in the impact of parental death. However, the lack of socioeconomic variation may also be influenced by factors such as compensatory agency
