Fathering in intact and divorced families: Ethnic differences in retrospective reports

The present study was designed to investigate whether ethnicity moderates the effects of divorce on young adults’ retrospective reports of fathering. An ethnically diverse sample of 1,989 university students completed measures of nurturant fathering, reported father involvement, and desired father involvement. Compared with participants from intact families, those from divorced families indicated lower levels of nurturant fathering and reported father involvement. These differences varied considerably by ethnicity. Reported fathering differences between participants from intact and divorced families were greatest in African Americans, Caribbean Islanders, and foreign‐born Cubans. These differences were smallest in non‐Hispanic Whites and Asians. Participants from divorced families reported greater levels of desired father involvement than did participants from intact families. These differences were not moderated by ethnicity.

Issues in Qualitative and Quantitative Risk Analysis for Developmental Toxicology1

The qualitative and quantitative evaluation of risk in developmental toxicology has been discussed in several recent publications.(^1–3) A number of issues still are to be resolved in this area. The qualitative evaluation and interpretation of end points in developmental toxicology depends on an understanding of the biological events leading to the end points observed, the relationships among end points, and their relationship to dose and to maternal toxicity. The interpretation of these end points is also affected by the statistical power of the experiments used for detecting the various end points observed. The quantitative risk assessment attempts to estimate human risk for developmental toxicity as a function of dose. The current approach is to apply safety (uncertainty) factors to die no observed effect level (NOEL). An alternative presented and discussed here is to model the experimental data and apply a safety factor to an estimated risk level to achieve an “acceptable” level of risk. In cases where the dose-response curves upward, this approach provides a conservative estimate of risk. This procedure does not preclude the existence of a threshold dose. More research is needed to develop appropriate dose-response models that can provide better estimates for low-dose extrapolation of developmental effects.     

The Stability of Social Groups in Childhood and Adolescence: The Role of the Classroom Social Environment.

This study provides a developmental analysis of childhood and adolescent social relationships within the school context. The social groups of 220 fourth graders and 475 seventh graders were tracked over a one year interval. The initial results indicated that approximately 30% of the social groups were identified as stable in that they maintained at least 50% of their membership over the one year interval. However, the stability in group affiliations was a function of the stability of the composition of the classroom. When schools did not promote classrooms as a unit, only 6.8% of social groups were stable, as compared to 55% of groups being stable when the school did promote classrooms as a unit. This school effect in group stability was demonstrated by a high correlation (rs = .97) between classroom stability and group stability. Even in unstable classrooms, individuals were more likely to maintain affiliations when group members were assigned to the same classroom. This work suggests that stable environments promote stable relationships, which in turn, may promote greater continuity in the organization of behavioral patterns.     

Intimate relationships and changing patterns of money management at the beginning of the twenty-first century

Drawing on British data from two annual sweeps of the ISSP eight years apart in 1994 and 2002, for modules focusing on 'Family and Changing Gender Roles', this paper examines the extent to which changes in women's labour market participation, changing ideologies/discourses of gender and changing forms of intimate relationships are affecting the ways in which couples organize household money, and the implications of such changes for recent theories of intimate relationships. The analysis indicates that by 2002, the type of relationship respondents had established, together with their social class position, were both independently related to the ways in which they managed money, after controlling for socio-economic and cultural or discursive factors. Our findings also provide a degree of support for the thesis of a partial decline in the male breadwinner model of gender, as indicated by small declines in the use of the relatively inegalitarian female whole wage and housekeeping allowance systems which were most likely to be used by married couples and cohabiting fathers, expressing relatively traditional ideologies/discourses of breadwinning - and a slight increase in the use of the partial pool, which was most likely to be used by childless cohabiting couples in which male partners expressed less traditional ideologies of breadwinning and women were in middle-class jobs with incomes high enough to facilitate partially separate finances. We also suggest, however, that in so far as cohabiting couples earning different amounts define equality as contributing equally to household expenditure, it is possible that rather than being associated with shifts to greater equality in access to money for personal spending and saving, the partial pool may be associated with marked inequalities, because it may enable gender inequalities generated in the labour market to be more directly transposed into inequalities within households, despite the decline of traditional discourses of male breadwinning and the increasing importance of egalitarian ideologies of co-provisioning.     

On the Detection of Contemporaneous Relationships Among Multiple Time Series

A study is carried out of a sampling from a half-normal and exponential distributions to develop a test of hypothesis on the mean. Although these distributions are similar, the corresponding uniformly most paerful test statistics are different. The exact distributions of these statistics my be written in terms of the incomplete gamma function. If the experimental data my be fitted by either distributions, it is advisable to carryout the test based on the half-normal distribution as it is generally more powerful than the one based on the exponential one.

You don’t forget where you come from: linking formation and operations in publicly funded innovation networks

Abstract

Publicly funded innovation networks (PFINs) are an increasing form of organizing joint innovation activities. Yet, little is known about this form of organization which mixes characteristics of centralized and de-centralized innovation networks. This research investigates how processes of network formation affect its operation in PFINs as a hybrid form between centralized and de-centralized networks. Presenting rich data from a PFIN in the Scandinavian maritime industry, the findings show three patterns linking network formation and operation. The first pattern – well-aligned centralized and de-centralized approaches – in network formation resulted in well-functioning network operation. The second pattern – misalignment between centralized and de-centralized approaches in network formation resulted in stagnating innovation activities during network operation. The third pattern – a pre-dominant de-centralized approach during network formation resulted in unconnected sub-activities during network operation. This research contributes by showing the importance of utilizing both centralized and de-centralized approaches and aligning them to enable well-functioning network formation and operation.     

Peer relationships during late childhood in internationally adopted and institutionalized children

The aim of this study was to analyse the interpersonal relationships in the school context of children living in different care settings (adoptive families, residential care centres, birth families). Participants were 76 children between eight and fourteen years of age (M = 10.78, SD = 1.38), belonging to one of three groups: international adoptees, children living in residential care in Spanish institutions, and a comparison sample of Spanish children living with their birth families with no connection with child protection. Sociometric information was collected in the classroom of each child during school hours. Internationally adopted children from Russia showed considerable difficulties in their relationships with peers; they were more likely to be rejected and their peers described them as less prosocial and somewhat more aggressive. With a better sociometric position than the adoptees, children in residential care were rated by their peers as more aggressive and less prosocial than the normative population. Coordination and integrated work between the family, protection centres, schools, and other social services should be a strategic priority in the promotion of healthy social development in these groups of children.     

Examining risk and protective factors on progression of romantic relational aggression among young adults: Parental control,parental care,and peer social support

Abstract

Romantic relational aggression is related to numerous mental health consequences but risk and protective factors of perpetrating this type of aggression, historically, have been unclear. This study fills in the research gap by evaluating the impact of parental control, parental care, and peer social support on later perpetration in romantic relational aggression among 84 predominately Chinese college students. Results revealed the positive association between parental control and perpetration in romantic relational aggression, however, this association diminished in the presence of high peer social support (HSS). Despite insignificance in the main effect, parental care was negatively correlated with later perpetration in romantic relationship in the HSS group while a positive association was found in the low peer social support (LSS) group. These highlights provided evidences how parental control and parental care during childhood could be risk factors for later romantic relational aggression as well as how current social support from peer could serve as a protective factor on the negative influence from parent–child relationships.
