The Relations between Infant Negative Reactivity,Non‐maternal Childcare,and Children's Interactions with Familiar and Unfamiliar Peers

The present study examined the influence of children's experiences during non‐maternal childcare on their behavior toward unfamiliar peers. Participants included children classified as negatively reactive at four months of age (N = 52) and children not negatively reactive (N = 61), who were further divided into those who experienced non‐maternal care and those who did not. Children were observed during childcare at 24 months of age and in the laboratory with an unfamiliar peer at 24 and 36 months of age, where their wariness, dysregulation, and social engagement were assessed. Within the negatively reactive childcare group, children's positive interactions with peers during childcare at 24 months predicted lower levels of wariness toward an unfamiliar peer at 36 months. This relation was not significant for children not classified as negatively reactive. The findings suggest that the influence of non‐maternal childcare is dependent on a child's temperament and on the nature of peer interactions during care.     

Encouraging a peer in need: The impacts of social anxiety and peer familiarity

Extant research has produced conflicting findings regarding the link between social fearfulness and prosocial behavior, with some studies reporting negative relations and others reporting null effects. Furthermore, these studies have focused predominantly on toddlerhood, and few have examined prosociality between peers. The present study investigated whether the link between social anxiety and prosocial behavior (i.e., providing encouragement) varied depending on interpersonal and situational factors (i.e., one's familiarity with a peer, and the level of support sought by a peer, respectively). We tested this question using a multimethod approach, which included ecologically valid stress-inducing task and dyadic design with a sample of 9- to 10-year-olds (N = 447). Results revealed that social anxiety was related negatively to providing encouragement among familiar and unfamiliar dyads. In familiar dyads, however, this main effect was qualified by an interaction with the level of support sought by one's peer. Compared to those low in social anxiety, children high in social anxiety provided relatively less encouragement in response to higher levels of support seeking from their peers. The findings are considered in relation to theorizing regarding the effect of overarousal on children's prosocial behavior.     

Technical change and total factor productivity growth in swedish manufacturing industries

This paper is concerned with the measurement of total factor productivity(TFP) growth and technical change in Swedish manufacturing industries during the period 1964–1989. Two alternative formulations of technical change, viz., the time trend model and the general index model are used for measuring TFP growth and technical change. Measures of these are embedded in a cost minimization framework where we estimate the translog cost function along with the associated cost share equations. The cost function accommodates industry-specific variability through an error component model. The models are estimated using the iterative seemingly unrelated regression method after some transformations to the cost function. Empirical results show that the general index model is superior to the time trend model when the pattern of technical change and total factor productivity growth are examined.

Towards improved measurement of cognitive and behavioural work demands

Determination of the cognitive and behavioural demands of work is an important part of holistic workplace intervention. Attention to these factors is especially important when developing return-to-work programs for persons with reduced cognitive, behavioural or psycho-emotional capacity, and when designing risk management programs in organizations. Occupational therapists have the background knowledge and skills to assess these components of work, but often lack valid and reliable measurement tools. This paper reports on three field studies that assessed the reliability and validity of ratings made by novice users of the City of Toronto Job Demands Analysis, which includes a measure of cognitive and behavioural work demands. Numerous challenges to accuracy and reliability that are common to empirical measurement were disclosed, including the necessity for clear and strong definitions, and the importance of thorough rater training. Implications for therapist training and mentorship are discussed.
