Disappearing Décalage: Object Search in Light and Dark at 6 Months

Infants search for an object hidden by an occluder in the light months later than one hidden by darkness. One explanation attributes this décalage to easier action demands in darkness versus occlusion, whereas another attributes it to easier representation demands in darkness versus occlusion. However, search tasks typically confound these two types of demands. This article presents a search task that unconfounds them to better address these two explanations of the “dark advantage.” Objects were hidden by submersion in liquid instead of occlusion with a screen, allowing infants to search with equally simple actions in light versus dark. In Experiment 1, 6‐month‐olds unexpectedly showed a dark disadvantage by discriminating when an object was hidden in the light but not the dark. Experiment 2 addressed the possibility that representation demands were higher in the dark than the light and showed that infants’ search in the dark increased to match that in the light, but not exceed it. Six‐month‐olds can thus search for a hidden object both when action demands are simplified and when a noncohesive substance rather than a cohesive occluder hides the object, supporting aspects of both action‐demand and representation‐demand explanations of décalage in search behavior.     

CALIBRATING MEASURES OF FAMILY ACTIVITIES BETWEEN LARGE- AND SMALL-SCALE DATA SETS

Two studies of working families are combined to demonstrate a strategy for producing reliable estimates from the combination of self-reported (large N) and observational (small N) data. Both studies examine where and how dual-career families spend time at home. The 500 Family Study is sociological and uses self-reported time diary data from a national sample; the CELF study is anthropological and uses observational scan sampling data from a regional sample of 32 families. The data are combined as if they constitute one sample, and an analytic solution for establishing the reliability of the resulting composite estimates of time use is provided. Merging the data sets provides validation for each study, neither of which is without potential methodological weaknesses. The advantages of combining data from the independent data collection methods are discussed, and selected substantive findings on families' activities are highlighted, illustrating similarities and differences between findings in the independent and combined data sets. Results show that working families spend significant time in a small spectrum of home spaces, particularly kitchens and living rooms, with leisure activities prevailing, but mothers, fathers, and children differ in where and how they spend their time. Overall, a template for merging data from different disciplines and methods is provided.     

Induced inefficiency as a response to the union threat

Milkman and Mitchell (1995) extend Rosen’s (1969) threat-effect hypothesis to suggest that the threat of unionization can induce inefficient underutilization of labor by nonunion firms. If firms follow this strategy, the apparent paradox of competitive coexistence in the face of higher union wages reflects induced nonunion firm inefficiency rather than superior union firm efficiency. Furthermore, this strategy decreases demand for nonunion workers in a partially unionized industry. A generalized cost function analysis of data from sawmills in the Pacific Northwest yields evidence that nonunion firms use this strategy.     

Helping mothers to combine paid and unpaid work–or fighting unemployment? the ambiguities of french family policy

The Family Law' passed by the French Parliament in July 1994 introduced important changes in family policy. Because the number of publicly subsidised childcare places is still very limited, and to encourage families to create employment (by employing childcare workers), the government has chosen to encourage the development of a variety of childcare provisions by increasing the financial incentives payable to parents employing a private nanny or child-minder. The same rationale of reducing unemployment has also prompted the decision to extend existing child rearing benefit to families having a second child. This measure has been very successful in encouraging women to retire from the labour market. The high cost of these changes has been shared by Social Security and the State. However, the changes have contributed to the increased polarisation between higher and lower wages families, with highly qualified mothers, who can afford childcare costs, remaining in paid employment after giving birth, and lower qualified mothers leaving the labour market.     

Factors associated with expectation of household's future financial condition

Path analysis is used to examine the causal relationships among selected objective and subjective factors associated with a household's expectation of future financial condition. Results indicate that respondents who perceive the effect of changes in the external environment on their own household's financial condition as positive are younger, have higher net worth, perceive more internal control over their situation, and report that most of the changes in the external environment are positive. Respondents who are younger, have higher income, perceive more internal control over their situation, and believe the effect of changes in the external environment on their household's financial condition are positive are more likely to be optimistic about their financial future. It is important that educators and financial advisors recognize the significant role perception of being in control plays in determining expectations of future financial condition.Journal Paper No. J-15256 of the Iowa Agriculture and Home Economics Experiment Station, Project No. 2809.

Exploring the Link Between Caregiver Affect and Adolescent Sexual Behavior: Does Neighborhood Disadvantage Matter?

In a sample of urban youth (N = 1,070), we examined the links between primary caregiver affect (i.e., warmth and hostility) and two measures of sexual behavior in adolescence - early sexual initiation and sex with multiple partners. We also examined the extent to which neighborhood disadvantage moderated associations between caregiver affect and adolescent sexual behavior. We found that caregiver hostility was positively associated with early sex and sex with multiple partners in neighborhoods characterized by high levels of disadvantage, but inversely associated with both sex outcomes in neighborhoods characterized by low levels of disadvantage. Caregiver warmth, on the other hand, was inversely associated with early sexual initiation and sex with multiple partners in all neighborhoods regardless of neighborhood disadvantage.     

Listening within the Social Contexts of Tutoring: Essential Component of the Mentoring Relationship

This qualitative research study targeted fourth grade at-risk children in a culturally diverse elementary school in a mid-sized city in the southwestern United States. The purpose of the study was to describe the nature of social interactions within the context of tutorial sessions and to describe the role of listening within the mentoring relationship. Major findings were that highly successful tutors were skillful communicators who modeled effective listening skills, used body language effectively, were knowledgeable about students' cultures, and possessed a social conscience.
