Maternal enhancing responses to adolescents’ positive affect: Associations with adolescents’ positive affect regulation and depression

Mounting evidence indicates that deficits in positive affect (PA) regulation are implicated in youth depression. Although parental responses to youths’ PA expressions have been linked to youth regulation of negative affect, no study has directly examined whether parental responses are linked with youth PA regulation strategies. The present study utilized a novel observational measure to test whether maternal active‐constructive responses to youths’ PA were uniquely associated with youth effective PA regulation strategies and, subsequently, depressive symptoms. Ninety‐two adolescents between the ages of 11 and 18 (M_age = 14.22, Girls = 62%) and their primary female caregivers (M_age = 41.40, 88% biological mothers) completed a series of questionnaires and engaged in a Plan a Day Trip interaction task. Results revealed that observed maternal active‐constructive responses to adolescents’ PA were uniquely associated with adolescents’ effective PA regulation strategies which, in turn, were related to lower depressive symptoms. These findings underscore the importance of parental responses to PA when sharing positive experiences for specifically targeting adolescents’ responses that generate and sustain PA.     

The cocos-keeling islands: A demographic laboratory

The Cocos Islands, which are situated in the Indian Ocean approximately halfway between Colombo and Fremantle, were first peopled early in the nineteenth century and were gradually developed as a very isolated coconut plantation with a labour force consisting partly of persons of Malay stock descended from the original group of settlers and partly of Bantamese contract labourers from Java. As the Cocos-born population increased in size, the dependence on contract labour decreased and, before the end of the century, all immigration ceased. The 1947 Malay population of the islands was about 1,800.

The islands are fascinating from a demographer's point of view because there was a virtually complete registration of live births, deaths and marriages and a partial registration of stillbirths. With these registration records it was possible to construct the life history of every individual from birth, through infancy and childhood to marriage, and thence through fatherhood or motherhood to death.

The picture revealed by an analysis of these records is that of a population with very high fertility and with mortality at a high level before the first World war and at a medium level after that war. Crude birth rates varied between 50 and 60 per thousand population during the period 1888 to 1947. Crude death rates were between 30 and 40 per thousand population until 1912 but under 2.0 per thousand population after 1918.

Most Cocos girls married before reaching the age of 20 and there were an average of between eight and nine live births per woman living through the childbearing period. There was a steady decline in the average number of live births with advancing age at marriage from age 16 onwards. A significantly high proportion of those dying in the middle of the childbearing period had never married, but the fertility of those marrying at an early age (14, 15 and 16) and dying before reaching the age of 36 was slightly higher than that of those who married at a similar age and survived. Women who survived to the age of 55 were of higher fertility than those who died between the ages of 40 and 55. An analysis of birth intervals revealed significant differences (a) between birth intervals after a stillbirth or after a live birth in which the child died in early infancy, and birth intervals after a live birth in which the offspring survived for longer than 0.4 years, and (b) between the interval from first to second birth and the subsequent birth intervals. There was a difference of almost exactly a year between the average birth interval after a stillbirth or live birth ending in a neo-natal death and the average birth interval after the birth of a child surviving to age 2; there was a similar difference of a year between corresponding median birth intervals.

From 1888 to 1912 infant mortality was well above 300 per thousand. After 1918 infant mortality averaged rather under 100 infant deaths per 1,000 live births. The reduction in infant mortality rates was accompanied by an increase in the mortality of children aged 1 to 4, and the heavy incidence of mortality at these ages after 1918 is the most striking feature of the analysis of mortality by age. Whilst mortality in infancy fell much more heavily on males than on females, early childhood mortality was much higher in Cocos for girls than for boys. The life table computed for the period 1918 to 1947 indicated a life expectancy of about 50 years for males and 47 years for females.     

Exporting Poor Health: The Irish in England

In the twentieth century, the Irish-born population in England has typically been in worse health than both the native population and the Irish population in Ireland, a reversal of the commonly observed healthy migrant effect. Recent birth cohorts living in England and born in Ireland, however, are healthier than the English population. The substantial Irish migrant health penalty arises principally for cohorts born between 1920 and 1960. In this article, we attempt to understand the processes that generated these changing migrant health patterns for Irish migrants to England. Our results suggest a strong role for economic selection in driving the dynamics of health differences between Irish-born migrants and white English populations.     

Data-Intensive Science and Research Integrity

In this commentary, we consider questions related to research integrity in data-intensive science and argue that there is no need to create a distinct category of misconduct that applies to deception related to processing, analyzing, or interpreting data. The best way to promote integrity in data-intensive science is to maintain a firm commitment to epistemological and ethical values, such as honesty, openness, transparency, and objectivity, which apply to all types of research, and to promote education, policy development, and scholarly debate concerning appropriate uses of statistics.     

Bullying and 'Theory of Mind': A Critique of the 'Social Skills Deficit' View of Anti-Social Behaviour

Bullying in schools has been found to be widespread. The popular stereotype of a bully, supported by theories based on the social skills deficit model, is of a powerful but 'oafish' person with little understanding of others. In this article, we trace the origin of this view, and present an alternative view: that some bullies, at least, will need good social cognition and theory of mind skills in order to manipulate and organise others, inflicting suffering in subtle and damaging ways while avoiding detection themselves. Such skills, although likely to be utilised in all bullying, may be particularly useful for ringleader bullies and in the indirect forms of bullying which are more common between girls. Suggestions for further research in this area are made, and implications for anti-bullying work briefly discussed.
