Understanding Interdisciplinary Collaborations as Social Networks

The dynamics of interdisciplinary collaboration invite further investigation if we are to make this endeavour more rewarding and productive. We are using social network analysis to track the development of a new interdisciplinary collaboration on complex interventions to improve population health. It involves nineteen scholars across four countries. We report the Baseline network of formal relationships among the scholars, along with the impact of the collaboration on these relationships in the first 18 months. We observed statistically significant increases in the density of six types of relationship networks: citing publications by other members of the collaboration, email contact, meeting with each other (outside of the formal annual meeting), visiting one another's institution, submitting research grants together and working on research projects together. The initial strategic role in the network of key 'gate keepers' has not altered substantially (betweenness centralization of the networks), but reciprocity has increased, that is, people are more likely to cite those who have cited them and work together. Increased collaboration is also reflected in the rise in number of subgroups over time and the increase in the average number of subgroup memberships. Use of social network analysis to understand the dynamics of interdisciplinary collaborations is a relatively new field. It invites reflection about what the optimal network structures for interdisciplinary collaborations would look like.     

Tampering with Tradition: Rationales Concerning Women��s Married Names and Children��s Surnames

Despite advances in gender equality in recent decades, the majority of women continue to change their names upon marriage and parents overwhelmingly opt to give children the father??s surname. In two correlational studies, both involving undergraduate samples from Toronto, Canada, we examined gender differences in naming preferences and in justifications underlying a traditional name choice. Men were more likely to prefer traditional choices in both women??s married names (Study 1; N?=?68) and children??s surnames (Study 2; N?=?63), and were also more likely to endorse most potential rationales for these choices. Traditional choices were associated with such factors as concern regarding family dynamics, whereas nontraditional choices were associated with such factors as a desire to increase gender equality.     

Child care before 6 months of age: a qualitative study of mothers' decisions and feelings about employment and non‐maternal care

Employment of women while their children are infants has increased in the UK in the last decade. This study of 57 employed mothers of infants less than seven months old examined their retrospective reports of planning child care and their contemporaneous feelings about the child care they were using, based on qualitative interviews. Issues addressed included mothers' reasons for returning to employment at that time, their theoretical preferences among a range of child care types and providers and the process of making actual choices, including the range and types of advice received and the involvement of fathers. Mothers were also encouraged to discuss their feelings about how child care was working out once the infant was settled. Continuing concerns expressed by mothers included the importance of open communication with caregivers, their desire to keep control over infants' daily lives and upbringing, worries about infants' safety and concerns about the levels of cognitive stimulation they received.

Is there a psychopathic element in adolescent drinking? A longitudinal study

While previous studies have examined the relationship between psychopathic traits and alcohol use in adolescents, limited empirical investigations of the longitudinal bidirectional effects of psychopathic traits and alcohol use have been conducted for this age-group. The purpose of the present study was to examine the longitudinal associations among adolescent’s psychopathic traits and their alcohol use, in order to illustrate the directional causal relationship between the two constructs, taking into account demographic effects. Participants were 334 adolescents from Cyprus. The participants responded to self-report questionnaires in two consecutive measurements within a six-month interval. Data were analyzed with cross-lagged structural equation modelling. Results indicated that the Dependence alcohol symptoms in Time 1 were significant predictors of the Interpersonal dimension of psychopathy in T2, and the Behavioural dimension of psychopathy in T1 was a significant predictor of Dependence alcohol symptoms in T2, regardless of previous levels of psychopathy and alcohol use, gender and age effects. Implications for research are discussed.     

Community Violence as It Affects Child Development: Issues of Definition

The state of the art of definition of community violence as it relates to child development was examined in terms of the definitions used in 23 empirical studies. In all cases community violence was defined in terms of what were assumed to be measurements obtained as linear combinations of a priori numerical weighting of responses to questions--asked either of a child or of the parent of a child--about experiencing and/or witnessing and/or hearing about instances of violence. Thus, the definitions can be seen to represent the perspectives of 2 kinds of observers--the child or the child's parent--and 3 levels of closeness to violence--experiencing, witnessing, or hearing about violence. Combining these perspectives and levels, the following 8 different definitions could be seen to be used in the practice of 1 or more of the 23 empirical studies: Child Self-Report (perception) of either (1) experiencing, or (2) witnessing, or (3) experiencing and witnessing, and hearing about violence; or Parent Report (perception) of the Child (4) experiencing, or (5) witnessing, or (6) experiencing and witnessing and hearing about violence, or (7) = (1) + (4), or (8) = (3) + (6). In almost all the examples of research definitions it was assumed implicitly and without test of the assumption that different violent events were interchangeable, and usually it was assumed (again without test) that the magnitudes of different violence events were equal. Usually, an unstated theory of stress appeared to guide the measurement definition, but in one study definitions were developed and tested in terms of a clearly-stated theory of learning. It was concluded that definition of community violence is a measurement problem; that very likely it is multidimensional; that it could be more nearly solved if better attention were given to specifying it in terms of theory that can be put to test and by attending to basic assumptions and principles of measurement.

When do stereotypes become really consensual? Investigating the group-based dynamics of the consensualization process

Although it has long been recognized that stereotypes achieve much of their force from being shared by members of social groups, relatively little empirical work has examined the process by which such consensus is reached. This paper tests predictions derived from self-categorization theory that stereotype consensus will be enhanced (a) by factors which make the shared social identity of perceivers salient and (b) by group interaction that is premised upon that shared identity. In Experiment 1 (N=40) the consensus of ingroup stereotypes is enhanced where an ingroup is judged after (rather than before) an outgroup. In Experiment 2 (N=80) when only one group is judged, group interaction is shown to enhance the consensus of outgroup stereotypes more than those of the ingroup—an apparent ‘outgroup consensus effect’. In Experiment 3 (N=135) this asymmetry is extinguished and group interaction found to produce equally high consensus in both ingroup and outgroup stereotypes when the ingroup is explicitly contrasted from an outgroup. Implications for alternative models of consensus development are discussed. © 1998 John Wiley & Sons, Ltd.     

Parent-infant interaction: a growth model approach

The aim of this study is to compare the interaction of fathers and mothers with their 10–12 months old infants (n = 97; parental sensitivity and mood, and infant mood) during five structured contiguous play segments, and to examine the utility of individual growth modeling. Conventional comparison of means across play-segments showed that parents were equally responsive, but mothers were happier than fathers, and infants were equally happy during interaction with both parents. Sensitivity and mood were more strongly related for mothers than for fathers. Uni- and multivariate growth models revealed fine-grained patterns not seen in conventional analysis: (a) parental and infant mood decreased across play more for mothers than for fathers, (b) parental sensitivity in one play-segment predicted parental mood and infant mood in the next segment, (c) change in infants’ mood was related to change in sensitivity in mothers, and to change in mood in fathers, and (d) mothers’ sensitive interaction with the infant was predicted by family socio-demographic background.     

Committed to succeed: Commitment determines reactions to upward relationship comparisons

Individuals encounter numerous examples of happy relationships in their social networks and through the media; however, it is unclear how comparisons to superior couples affect one's own relationship. We examined individuals' responses to upward relationship comparisons by exposing dating and married participants to highly successful relationships drawn from their own lives (Study 1) and an exemplar given to them (Studies 2–3). We predicted that moderately committed individuals would evaluate their relationship against the superior relationship, and consequently be less motivated to engage in relationship‐maintenance behaviors. In contrast, highly committed individuals would be inspired by the superior relationship and view their relationship more positively. Across all studies, higher commitment yielded more positive responses to upward relationship comparisons than did lower commitment.
