The relations between maternal mental state talk and preschoolers’ behavioral adaptation and school readiness: moderation by emotion situation knowledge

This study investigated the extent to which associations between mothers' elaborated talk about mental states and preschoolers’ behavioral adaptation (i.e., social competence and internalizing and externalizing behavior) and school readiness were moderated by emotion situation knowledge. Families (N = 120) were mostly middle‐income and White and 70 of the preschoolers (M = 50.65 months, SD = 6.19) were boys. Results revealed a positive association between elaborated maternal mental state talk and social competence, but only for children average and high in emotion situation knowledge. For children low in emotion situation knowledge, there was a positive association between elaborated maternal mental state talk and internalizing behavior. There also was a negative relation between elaborated maternal mental state talk and school readiness for preschoolers low in emotion situation knowledge. Findings highlight the importance of considering emotion situation knowledge when examining associations between elaborated maternal mental state talk and young children’s social behavioral adaptation and readiness for school.     

Are corrupt acts contagious?: Evidence from the United States

This paper adds to the literature by shedding new light on the causes of corruption. Specifically, we provide evidence on the extent to which corruption might be contagious. In other words, what is the extent to which a demonstration effect is at play at inducing corrupt acts? Using state-level U.S. data over the 1995–2004 period, the results show that the effect of neighboring corruption is positive and statistically significant in all cases, implying that corruption does appear to be contagious. Specifically, a 10% increase in corruption in neighboring states appears to increase corruption in a state by about 4–11%. Of the different types of government activity, the size of defense and non-defense federal sectors in a state seem to have opposite effects on corruption, with the former contributing to corruption and the latter serving as a deterrent. The size of the state and local governments does not seem to be relevant. Of the variables controlling for detection and punishment of corrupt individuals, greater corrections employment reduces corruption, while greater judicial employment seems to increase corruption. Changes in the police force do not seem to have a statistically significant impact. These findings generally hold when we control for the disproportionate effects of the Washington, DC area and when a pooled data set is estimated. Contagion effects are also found for other crimes. Policy implications are discussed.     

The impact of a respite volunteer ‘buddy’ programme on behavioural and psychological well-being in young carers

Young carers often face a great amount of emotional burden and have high practical and social responsibilities. The role of being a young carer is associated with behavioural, developmental, physical and psychosocial problems that may not only affect the individual in childhood but also in adulthood. The aim of this study was to investigate the effect of a Danish respite volunteer programme called The Buddies for Children and Youngsters Programme on young carers' (n = 49; aged 6–16) social–emotional functioning. A pre–post-design was applied, and data were collected through the parent version of the strengths and difficulties questionnaire (SDQ), here with an impact supplement at baseline and at the end of the programme (after 4 months). The programme showed a positive impact on emotional symptoms, hyperactivity symptoms, conduct problems, peer problems, prosocial aspects and impact aspects, with mean differences values of −2.50 (p = .000), −0.62 (p = .271), −1.18 (p = .000), −0.74 (p = .008), 0.62 (p = .004) and −0.88 (p = .007), respectively. Furthermore, a large effect was found for the total difficulties score: −5.03 (p = .000). In conclusion, the programme seems promising considering its effect on young carers' social–emotional functioning. However, future research should include comparative studies with a longer duration.     

Farsightedness and Cautiousness in Coalition Formation Games with Positive Spillovers

We adopt the largest consistent set defined by Chwe (1994; J. Econ. Theory 63: 299–325) to predict which coalition structures are possibly stable when players are farsighted. We also introduce a refinement, the largest cautious consistent set, based on the assumption that players are cautious. For games with positive spillovers, many coalition structures may belong to the largest consistent set. The grand coalition, which is the efficient coalition structure, always belongs to the largest consistent set and is the unique one to belong to the largest cautious consistent set.     

A test of the Core,Bargaining Set,Kernel and Shapley models in n-person quota games with one weak player

n-person (n – 1)-quota-games where the quotas are positive for certain n – 1 (strong) players and negative for the remaining (weak) player, are discussed. Normative solutions predicted by the Core,the Kernel, the Bargaining Set, the Competitive Bargaining Set, and by the Shapley Value are presented and exemplified.Each of twelve groups of subjects participated in a four-person and a five-person (n – 1)-quota games with one weak player. The weak player was always excluded from the ratified coalition. The division of payoffs among the strong players was more egalitarian than the Kernel solution but less egalitarian than the Shapley value. The Core and the Bargaining Sets were fully supported for the two strongest players, but less supported for the other players. Analyses of the bargaining process confirmed a dynamic interpretation of the Bargaining Set Theory.This research was performed while the author was at the University of North Carolina. The research was partially supported by a PHS Research Grant No. MH-10006 from the National Institute of Mental Health. The author thanks Professor Amnon Rapoport for helpful advice in the design of this study.     

Someone to Lean on: Assessment and Implications of Social Surrogate Use in Childhood

A social surrogate is a person who helps a shy individual deal with the stresses of a social situation. Previous research has only investigated social surrogate use in adults. The purpose of the current study was to develop and evaluate a new self‐report measure of social surrogacy in middle childhood and to explore the implications of this phenomenon for children's socioemotional functioning. Participants were N = 328 children in grades 3–5 (Mean_age= 9.45, Standard deviation = .93). Children completed the newly developed child social surrogate questionnaire (CSSQ) as well as self‐report assessments of shyness, loneliness, social anxiety, peer victimization, and self‐perceptions. Results indicated good psychometric properties and evidence of construct validity for the CSSQ. Social surrogacy was related to elevated shyness, social anxiety, and victimization. Contrary to expectations, there was also some evidence to suggest that social surrogacy may have particularly negative implications for shy children.     

Hostile interpretation as a transdiagnostic factor for cooccurring anxiety in boys with aggressive behavior problems

Many children with aggressive behavior problems also suffer from anxiety. This cooccurrence may perhaps be explained by transdiagnostic factors. Identifying these factors seems crucial, as they may be important targets to treat these cooccurring problems effectively. This two-study paper investigates whether hostile interpretation of others’ intentions is a transdiagnostic factor for cooccurring aggression and anxiety problems, examining two samples of boys in middle childhood. We assessed boys’ aggression and anxiety using teacher-report in Study 1 (N = 84, M_age = 10.10), and parent-report in Study 2 (N = 115, M_age = 10.55). In both studies, we assessed hostile interpretation using vignettes describing ambiguous provocations by peers. Both studies revealed a strong association between aggression and anxiety problems, underscoring the necessity to examine factors that can explain this cooccurrence. However, in neither study was this association reduced when we added hostile interpretation to the model, suggesting that hostile interpretation did not function as a transdiagnostic factor in our samples. One possible explanation for these findings is that hostile interpretation predicts both aggression and anxiety problems, but in different children. We, therefore, encourage scholars to conduct more research to explain the high comorbidity of aggression and anxiety problems in children. Future research should also examine hostile interpretation as predictor or transdiagnostic factor for aggression and anxiety problems in more diverse population, including girls and other age groups.     

Where o’ where did my baseball cards go?: Race,performance, and placement in the Topps ERA, 1956–1980

On the surface, baseball cards appear to be little more than uninteresting object of child's play; yet they provide invaluable data for assessing unique aspects of the social order. They reveal much about the state of society when they were produced and the people who collected them. This paper examines the unique numbering system the Topps company developed to differentiate among the “royalty of the diamond” from 1956 to 1980. Their system assigned to each card in a set a number that explicitly designated its placement, while implicitly establishing a hierarchical ordering among the players, ostensibly based on performance. It is arguable whether the numbering system Topps developed was based on performance or the ascribed characteristic of race. The results of our work suggest that player performance, not race, was the primary factor in the assignment of “prestigious” card numbers in Topps’ system.     

Investigating the Effects of Trauma-Related Research on Well-Being

Using an experimental design, we investigated the impact of participation in trauma-related research on well-being in a sample of 219 higher education students. We created five conditions that exposed participants to questions about life events. A sixth condition represented a control condition. Exposure conditions varied according to whether they contained yes/no questions about events that entailed stress, stigma, trauma, or sexual violation. We operationalized well-being by measuring positive and negative affect, state anxiety, and positive reactions to research. Across exposure conditions, participants reported low levels of negative affect and generally positive reactions immediately after participation. The most negative and least positive responses followed exposure conditions that contained questions about stressful events and sexual violation. We discuss implications of our findings for ethics review board practices.

Interpersonal synchrony is associated with infants’ reactions to subtle changes in caregiver-infant interactions

The present study examined the role of interpersonal synchrony between mothers and their 4-month-old infants (N = 40) in infant responses to a modified interaction where mothers continually looked and verbalised towards but did not engage with their children. During a natural interaction we observed behavioural synchrony and for a subsample of infants (n = 20) measured change in their salivary oxytocin from before to after the natural interaction. During the modified interaction we observed infant gaze, positive, and negative affect. We found that higher interpersonal synchrony was related to longer infants’ social gaze and shorter displays of negative affect during the modified interaction. Increase in infant oxytocin was also associated with longer gaze, but also longer negative and shorter positive affect during the modified interaction. Our results show that interpersonal synchrony allows infants to notice changes in interactions with others, but also helps them to regulate their emotions during such modified exchanges. These findings thus indicate the importance of synchrony experiences with caregivers for the development of early regulatory capacities.     

Living Healthy and Living Long: Valuing the Nonpecuniary Loss from Disability and Death

This analysis uses three valuation approaches—risk–risk tradeoff, paired risk–dollar comparison, and utility function estimation—to estimate the nonpecuniary cost associated with disability in late life. In addition, we obtain an estimate of the value of life using a paired risk–dollar comparison. The data were obtained from interviews with 548 persons using an iterative computerized questionnaire. Respondents reported a median value of life of $12 million. They were willing-to-pay .7–1.4 million to avoid disability in late life or approximately $47–$95 thousand for each year of disability over age 62. The results were robust to the valuation technique employed.     

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 contribution of emotion knowledge,language ability,and maternal emotion socialization style to explaining toddlers’ emotion regulation

In this study, we set out to advance understanding of the association between emotion knowledge (EK) and emotion regulation (ER) in toddlerhood, by innovatively examining a model that simultaneously takes into account both individual factors, such as age, gender, and language ability, and contextual factors, such as maternal emotion socialization styles (coaching vs. dismissing). Participants were 242 toddlers (141 girls; M_age = 28.79 months, SD = 3.48) and their mothers (M_age = 35.60 years; SD = 4.95). We evaluated children’s language ability and ER via parent‐report questionnaires, assessing their EK via a direct measure individually administered at the nursery. The mothers also completed a questionnaire on their own emotion socialization style. Children’s EK was positively correlated with their ER skills as reported by their parents. Structural equation modeling showed that emotion‐dismissing maternal behaviors were significantly negatively associated with toddlers’ emotional competencies whereas maternal emotion‐coaching styles were significantly positively associated with higher levels of these competences. Finally, language ability was positively associated with ER. We discuss the theoretical and educational implications of these outcomes, as well as potential new lines of inquiry.     

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.     

Testing the qualitative differences between empathy and personal distress: Measuring core affect and self-orientation

In two studies the emotional valence, the level of arousal and self-orientation of empathic concern and personal distress are tested. The empathic concern prevalence versus personal distress prevalence is induced through pictures in Study 1 (N = 62) and perspective-taking instructions in Study 2 (N = 60). Results of Study 1 show that participants in the personal distress-prevalence condition report significantly more negative emotional valence (d = .65), higher arousal (d = .48), and higher self-orientation (d = .57) than participants in the empathic concern-prevalence condition. Results of Study 2 show that participants in the self-oriented condition report the highest arousal, followed by participants in the other-oriented condition, and the objective condition (η_p² = .58). Concerning the increase of self-orientation, results show that it is mediated by the personal distress induced by self-perspective instructions. Similar results in emotional valence were found between self- and other-oriented conditions.     

Monotonicity of power and power measures

Monotonicity is commonly considered an essential requirement for power measures; violation of local monotonicity or related postulates supposedly disqualifies an index as a valid yardstick for measuring power. This paper questions if such claims are really warranted. In the light of features of real-world collective decision making such as coalition formation processes, ideological affinities, a priori unions, and strategic interaction, standard notions of monotonicity are too narrowly defined. A power measure should be able to indicate that power is non-monotonic in a given dimension of players' resources if – given a decision environment and plausible assumptions about behaviour – itis non-monotonic.     

从国家职能看明清官修史学

明清时期史学的一个显著特点是由国家组织的大规模的修史活动频繁,编纂了大量卷帙庞大的历史著作。这种史学现象的出现,与封建社会末期封建国家职能完善及统治者对发挥国家职能的自觉,有着十分密切的关系。无论是从发挥国家的社会职能讲,还是从发挥国家的统治职能讲,都对明清两朝的官修史籍的活动有重大的影响。封建国家的职能发挥,对于史学发展来说,是一把双刃剑,既有积极意义,也有消极意义。     

The Right to Remain Silent

The paper points out that in dynamic games a player may be better-off if other players do not know his choice of strategy. That is, a player may benefit by not revealing (or not pre-determining) the choice of his action in an information set he (thereby) hopes will not be reached. He would be better-off by exercising his ``right to remain silent' if he believes –- as the empirical evidence shows –- that players display aversion to ``Knightian uncertainty'. In this case, a player who behaves strategically, may wish to avoid revealing his strategy. This is true under various interpretations of the notion of ``strategy profiles'.     

Mentors' attachment dimensions,the quality of mentoring relationship and protégés' adjustment: a moderated mediation model

The relationships between mentors' (n = 168) attachment dimensions, the quality of mentoring relationship and protégés' (n = 187) level of adjustment after 8 months of mentoring intervention were explored. Unexpectedly, protégés of mentors with moderately negative childhood experiences and an insecure state of mind had higher levels of adjustment at the end of mentoring, whereas mentors' positive emotional childhood experiences contributed negatively to levels of adjustment. Furthermore, a dependent mother–protégé relationship moderated the relationship between mentors' attachment anxiety or avoidance and the quality of the relationship, such that it mediated the relationship between mentors' attachment anxiety and avoidance and led to a decrease in protégés' level of adjustment at the end of the intervention. The findings suggest that the disadvantages of a dependent mother–protégé relationship as regard protégés' level of adjustment interact with mentors' avoidance or anxiety, and that there may be an advantage in a mentor–protégé mismatch in terms of an anxious/dependent relational history.
