Polygenic Influences on Pubertal Timing and Tempo and Depressive Symptoms in Boys and Girls

This study used polygenic scoring (PGS) to test whether puberty‐related genes were correlated with depressive symptoms, and whether there were indirect effects through pubertal maturation. The sample included 8,795 adolescents from the Avon Longitudinal Study of Parents and Children (measures of puberty drawn ages 8–17 years; of depressive symptoms at age 16.5 years). The PGS (derived from a genome‐wide meta‐analysis of later age at menarche) predicted boys’ and girls’ later pubertal timing, boys’ slower gonadal development, and girls’ faster breast development. Earlier perceived breast development timing predicted more depressive symptoms in girls. Findings support shared genetic underpinnings for boys’ and girls' puberty, contributing to multiple pubertal phenotypes with differences in how these genetic variants affect boys' and girls' development.     

Parent – Adolescent Relationships and Girls’ Unhealthy Eating: Testing Reciprocal Effects

This longitudinal study tested the direction of associations between parent –adolescent relationships and adolescent girls’ unhealthy eating. Girls (N= 184) were seen at Time 1 (M age = 14.30 years), and then again 2 years later (Time 2; M age = 16.04 years). At both assessment periods, they completed measures that assessed their eating attitudes and behaviors, relationships with their parents, height, weight, and age of menarche. Whereas unhealthy family relationships have been hypothesized as a precursor to unhealthy eating attitudes and behaviors, it is also possible that increases in these behaviors contribute to more negative relationships within the family. Structural equation modeling was employed to simultaneously investigate the longitudinal influence of parent – adolescent relationships on girls’ unhealthy eating, and girls’ unhealthy eating on parent – adolescent relationships. The model was tested with the following controls: body mass (kg/m²), pubertal timing and age. A longitudinal direct effect was found for unhealthy eating on parent– adolescent relationships; however, no direct effect was found for parent– adolescent relationships on unhealthy eating over time. For middle– and late–adolescent girls, it appears that unhealthy eating behaviors and attitudes are predictive of less positive parent – adolescent relationships over time.     

Global Studies—The Handmaiden of Neoliberalism?

Abstract

The field of global studies has gained momentum over the past 20 years and today occupies a significant presence within many universities. As a result, there is now a burgeoning array of institutional support for global studies scholarship. Perhaps not surprisingly, concurrent to such institution-building there has been a spate of essays engaged with the question ‘what is global studies?’ that have promoted lively debate and commentary. In this essay, I ask a rather different question which is ‘who gets to define global studies, and what is at stake in these kinds of delineating efforts?’ I argue that debate about global studies demands the inclusion of multiple voices and perspectives from around the world. I conclude by urging global studies scholars to be deliberately conscious of their taken-for-granted assumptions with respect to power and the related capacity to speak for others from the global south and east who are largely still absent in defining this new field of inquiry.     

Pubertal Timing as a Potential Mediator of Adoption Effects on Problem Behaviors

Adopted children show more problem behaviors than nonadopted children. Given that internationally adopted individuals show earlier puberty than nonadopted individuals, and early puberty is associated with problem behaviors in nonadopted youth, we analyzed data from adopted domestic adoptees to determine whether problem behaviors could be explained by differences in pubertal timing. Relative to nonadopted controls (n = 153), domestically adopted girls (n = 121) had earlier menarche, earlier sexual initiation, and more conduct disorder symptoms. Age at menarche partially mediated the relation of adoptive status to sexual initiation, but not to conduct disorder symptoms. Extending findings from international adoptees, results show that domestic adoption is also linked to earlier puberty, and suggest early puberty as one mechanism linking adoption to problematic outcomes.     

Changes of sexual behavior related to temporal lobe disorders in man∗

The term ‘thorarche’ is proposed for the first seminal ejaculation in boys. A retrospective study on thorarche with 142 male, undergraduates (aged 18–21 years) indicated that 80.3% remembered their thorarche. Less than a third had had any instruction about its occurrence compared to the 91.7% of 133 female undergraduates who were instructed about menarche. The cause of thorarche for 92.4% was sexual, it occurred in sleep for only 25.6%. Approximately 43% felt thorarche made them aware that a milestone in masculinity had been attained but only 12.4% told anyone about it while just under half (41.7%) tried to hide its occurrence. In the case of the girls, 46.2% reported that menarche made them feel that a milestone in female development was attained and 49.1% told other girls about its occurrence. Of those who could recall the time of year of their thorarche a strong seasonal effect was apparent, the highest incidence occurred in the spring (40.6%) and summer (34.8%) sharply decreasing in the autumn (15.9%) and winter (8.7%). This was in contrast to menarche which was evenly distributed between spring, summer, autumn and winter. Unlike menarche, there was no evidence for a secular trend in thorarche.     

Young Muslim women of Bengali and Moroccan origin in Italy: multiple belongings,transnational trajectories and the emergence of European Islam

This paper investigates the multiple dimensions in the identity constructions of the daughters of the Muslim migrations to Italy. It focuses on the transformations in the way girls and young women relate to religion, in the transition from the generation of mothers, who emigrated from countries with a Muslim majority, to the generation of daughters, who grow up in a European context where Islam is a minority religion. It discusses ‘transmissions’, ‘translations’ and ‘betrayals’ in the migration experience, from a standpoint which highlights the specificities of gender and of generation. The article is based on an intersectional analysis of biographical accounts by Muslim girls and young women of Bengali and Moroccan origin who were born and/or grew up in Italy. Intersecting religious identity with other identity lines such as national belonging (to the parents’ country of origin and to the country where they were born or grew up), gender, class, color and age, multiple reactions and positions emerged. In this context, the religious dimension inherited/experienced/reinvented/called into question by the daughters of migrations appeared to be in constant evolution. Indeed, the stories contained herein of young Muslims tell of the emergence of European Islam.     

Early Childhood Maltreatment and Pubertal Development: Replication in a Population‐Based Sample

Early experiences are critically important for female reproductive development. Although a number of early childhood hardships predict earlier physical development in girls, research on specific populations suggests a distinct effect of childhood sexual abuse compared to other adversities. This study leverages the National Longitudinal Study of Adolescent Health (N = 6,273 girls) to test the generalizability of these findings, examining associations of early physical abuse, sexual abuse, and physical neglect with pubertal timing. Child sexual abuse predicted earlier menarche and development of secondary sexual characteristics, whereas other types of maltreatment did not. In addition to replicating results from smaller, more specialized samples, these findings reinforce the value of considering puberty within a broader “life span” continuum of birth to adolescence.     

Correspondence Between Gonadal Steroid Hormone Concentrations and Secondary Sexual Characteristics Assessed by Clinicians,Adolescents, and Parents

Adolescent sexual maturation is staged using Tanner criteria assessed by clinicians, parents, or adolescents. The physiology of sexual maturation is driven by gonadal hormones. We investigate Tanner stage progression as a function of increasing gonadal hormone concentration and compare performances of different raters. Fifty‐six boys (mean age, 12.7 ± 1.3 years) and 52 girls (mean age, 12.0 ± 1.6 years) were seen at baseline, 6 and 12 months. Estradiol and testosterone concentrations were determined from three morning serum samples and Tanner stage by three different raters (clinician, parent, and adolescent). Results confirm that Tanner criteria reflect gonadal hormone concentrations, and clinician rating provides optimal assessment. Detailed insight about the strengths and limitations of different raters is provided, augmenting the scientific understanding of pubertal development.     

The politics of rescue

In December 2002 the UN adopted a definition of ‘trafficking’ that critics worry discounts female agency in commercial sex and migration. This definition was already being used in Bosnia-Herzegovina (BiH) and Kosovo to tackle the violent sex industry that had developed alongside peacekeeping. This paper analyses official assumptions about female agency in commercial sex when ‘victims of trafficking’ (VoTs) are identified in BiH and Kosovo. In this context the Protocol definition helped extend access to resources to women and girls who could otherwise have been excluded. Those who had ‘been abroad’ before were no longer automatically rejected from VoT programmes but pathologised as sufferers of post traumatic stress disorder (PTSD); their illness establishing their ‘innocence’. Understanding the choice of migration for sex work as a symptom of PTSD allows anti-trafficking programmes to focus on victim rather than perpetrator behaviour. Strong pressures against tackling the way soldiers, police and contractors treat women and girls in the sex industry underlie this focus on victim behaviour. Those in the sex industry who are not ‘foreign’ or do not want to go ‘home’ are excluded from VoT status while anti-trafficking activity increases their risk of arrest, thus reifying the categories of innocent VoT and guilty prostitute.     

Asian girls in secondary schools: A British perspective

This paper reviews some of the specific difficulties faced by South Asian (referred to in the text as Asians) girls in British secondary schools. These include tension and anxiety, mainly caused by the differences in values and belief systems of home and school, psychosomatic illnesses, vocational aspirations, scholastic attainment and progression to higher education. In light of this review, some suggestions are offered which might alleviate these difficulties and thereby improve the equality of opportunity for Asian girls.     

Trajectories of Depressed Mood From Early Adolescence to Young Adulthood: The Effects of Pubertal Timing and Adolescent Dating

The effects of pubertal timing and adolescent dating on trajectories of depressed mood from early adolescence to young adulthood were examined among youths who participated in the National Longitudinal Study of Adolescent Health. Results showed that for both boys and girls, the trajectories of depressed mood between the ages of 12 and 23 took an inverse U‐shape with its peak in mid‐adolescence. Furthermore, pubertal timing was a significant predictor of depressed mood at age 12. The pubertal timing effect was nonlinear, suggesting that at age 12, early and late maturing youths were at risk of experiencing elevated levels of depressed mood. The adverse effect of off‐time maturation gradually dissipated over time. Moreover, in early adolescence, teenagers, particularly girls, were adversely affected by dating, and off‐time physical maturation exacerbated the negative effects of dating. However, the interactive effect of dating and pubertal timing gradually decreased with age. Our findings underscore the importance of examining junctures of biological and social challenges in adolescence to gain better understandings of young people's emotional experiences over time.     

Puberty and Transdiagnostic Risks for Mental Health

Puberty in girls represents a notable period of vulnerability for different psychological disorders. The research literature has primarily considered external and contextual factors that might explain these rises in symptomatology. In the present study, we investigate relations of pubertal status and timing with individual cognitive, emotional, and behavioral tendencies, commonly identified as transdiagnostic processes, in a sample of N = 228 girls (M_age = 11.75 years). We also test whether these transdiagnostic processes mediate associations of pubertal status and pubertal timing with depressive symptoms. Results support greater endorsement of rumination, co‐rumination, negative urgency, and both anxious and angry rejection sensitivity in girls with more advanced pubertal status, as well as in girls with early pubertal timing. Higher levels of transdiagnostic processes fully mediated associations of pubertal status and timing with depressive symptoms at significant and marginally significant levels, respectively. Although the data are cross‐sectional, these findings offer promising preliminary evidence that transdiagnostic processes represent an important mental health risk in early adolescent girls.     

Development and Lability in the Parent–Child Relationship During Adolescence: Associations With Pubertal Timing and Tempo

Adolescents' and parents' reactions to pubertal development are hypothesized to contribute to changes in family dynamics. Using 7‐year longitudinal data from the NICHD‐SECCYD (488 boys, 475 girls), we examined relations between pubertal development (timing, tempo) and trajectories (developmental change and year‐to‐year lability) of parent–child conflict and closeness from age 8.5 to 15.5 years. Changes were mostly characterized by year‐to‐year fluctuations—lability. Parent–child conflict increased and closeness decreased some with age. Pubertal timing and tempo were more consistently associated with lability in parent–child relationships than with long‐term trends, although faster tempo was associated with steeper decreases in parent–child closeness. Findings provide a platform for examining how puberty contributes to both long‐term and transient changes in adolescents' relationships and adjustment.     

Age at menarche among adolescent females in Zambia: implication for family formation

This study examines the relationships between age at menarche and two fertility related variables, expected age at marriage and expected number of children. The random sample consists of 525 secondary school-going females in the age range 13-21 years from the Copperbelt and Lusaka Central Provinces in Zambia. It was found that the age of menarche ranged from 10 to 18 years with a mean of 14.2 + 1.4 (mean + SD) years. The association between age at menarche and expected age at marriage was found to be weak but positive. Furthermore, the association of age at menarche with expected number of children was found to be weak but in the negative direction.     

Gender Atypical Behavior in Chinese School-Aged Children: Its Prevalence and Relation to Sex,Age, and Only Child Status

This study had three purposes: (a) to compare the prevalence of boys' and girls' gender-atypical behaviors (GABs) in a sample of Chinese school-aged children, (b) to examine the developmental pattern of GABs in Chinese boys and girls over the age range in question (6–12 years), and (c) to test the effects of being an only child on children's GAB expression. Parents of 486 boys and 417 girls completed a Child Play Behavior and Activity Questionnaire (CPBAQ) in regard to their own children, and a demographic information sheet. The frequency distribution for each gender-related behavior was calculated. The associations between sex, age, and only-child status, and CPBAQ scale scores were examined. Although most GABs (by their very nature) were exhibited infrequently in Chinese children, it was found that girls displayed GABs more frequently than boys did. The prevalence of GABs rose for girls as they grew older, but fell slightly for boys. The expressions of GABs in only children did not differ from that in children with siblings. Possible effects of Chinese culture (including the current only-child policy) on children's GABs are discussed.     

Sexual exploitation of children and international travel and tourism

The sexual abuse of children in developing countries by international tourists has received increasing attention recently, much of it concentrating upon the activities of paedophiles. This paper argues that the reduction in individual and social constraints associated with tourism and international travel, and an easier access to children for sex in certain destinations, also increases the potential for ‘situational’ child sexual abuse to occur. It reports on a literature study of the situation in the Philippines, Sri Lanka and Thailand, which found extensive evidence of the use of children for sex by international tourists. The paper suggests that remedial action is required on three levels: in the tourist receiving and sending countries and in the international arena.     

‘Counterurbanization’, interaction and functional change in a rural amenity area — A Canadian example

Recent explanations of population and economic change in rural communities in Canada, the United States, the British Isles and Australia are described and assessed. These are synthesized and evaluated in the south Georgian Bay area at the outer edge of Toronto's urban field. Custom census tabulations of data on migration, commuting and population change from 1971 to 1991 documented rapid population growth, a major increase in the elderly, significant migration from metropolitan centres and primarily local work-residence linkages in the study area. Much of the population increase occurred in residential nucleations with amenity attractions along the shoreline. Information from business directories was used to trace economic change. Many businesses formerly found in small rural service centres have centralized in larger communities, but new economic activities related to tourism, construction, finance, services, manufacturing and wholesaling replaced them in numerous settlements. Population continued to increase in places that had lost some or all of their businesses. Population growth and economic change may be attributed to local amenity attractions, location in an urban field, the ‘commodification of rurality’ and structural transformations in the economy. Deconcentration from the ‘Golden Horseshoe’ contributed substantially to population growth in the study area which appeared to be a ‘clean break’ from the Toronto area.     

Negotiating the dichotomy of Boffin and Triad: British-Chinese pupils' constructions of 'laddism'

Little research has examined constructions of gender among young British‐Chinese. This paper seeks to further understanding in this area, particularly in relation to notions of ‘laddism’ currently deployed in educational policy discourse around gender and achievement. As a group British‐Chinese boys tend to very high achievement in the British Education system. The notion of ‘laddish behaviour’ as an explanation for boys’ apparent underachievement in comparison to girls at GCSE level was discussed with British‐Chinese pupils. An overwhelming majority of British‐Chinese pupils supported this explanation, and a majority of these pupils applied notions of ‘laddish behaviour’ to British‐Chinese boys, to some extent contesting stereotypes of the Chinese as uniformly ‘good pupils’. However, the discourses of ‘the good Chinese pupil’ and ‘Chinese value of education’ were frequently drawn on by pupil respondents, with the result that the pupils often presented British‐Chinese manifestations of ‘laddism’ as mild versions in comparison with pernicious ‘others’. The paper discusses different presentations of laddism among some of the male respondents. It concludes by analysing the impact of ‘raced’ and gendered discourses on British‐Chinese constructions of masculinity. British‐Chinese boys may be able to adopt versions of masculinity which do not impede their learning, but this tended to result in their masculinity being problematised in teacher discourse.     

Research note: Safety,statistics and business cycles: a response to Nichols

This article considers three criticisms made by Nichols of my article on ‘industrial injuries in British manufacturing’. First, I argue that, notwithstanding recognised problems with data which include ‘minor’ accidents, this should not be rejected. I then question the reliability of the alternative data used by Nichols, namely that related to fatalities in British manufacturing. Second, I show that Nichols' claim that accident rates were increasing rather than decreasing in the years 1975–1979 can only be sustained if one shifts the years within which the trend is considered, and ignores other evidence to the effect that the latter part of the seventies witnessed a continuation of a long-term decline in accident rates in British manufacturing industries. Finally, in response to the charge that I misled readers in my original article, I note how Nichols' argument was indeed one that prioritised ‘business cycles; further, I indicate that Nichols has himself engaged in a highly focused reading of my earlier article.     

Associations Between Early Life Stress, Child Maltreatment, and Pubertal Development Among Girls in Foster Care

The present study investigated pubertal development in girls with maltreatment histories (N = 100), assessed at four time points over 2 years beginning in the spring of their final year of elementary school. This sample is unique, in that participants were subject to an unusual level of environmental risk early in life and resided in foster care at the start of the study. Analyses replicated the previously established association between sexual abuse and earlier onset of maturation and earlier age at menarche. Physical abuse was related to a more rapid tempo of pubertal development across the period assessed. These results strengthen previous investigations of childhood maltreatment and puberty, highlighting the complexity and specificity of early life experiences for later development.
