Play-fighting differs from serious fighting in both target of attack and tactics of fighting in the laboratory rat Rattus norvegicus

Play-fighting is often difficult to differentiate from inhibited or immature serious fighting because both may utilize many of the same behavior patterns. In the rat the two behaviors involve different targets of attack. During play-fighting, snout or oral contact is directed at the opponent's nape of the neck, whereas during serious fighting, male residents mostly direct their bites at the intruder's rump. Although similar to those used in serious fighting, the behavior patterns used during play-fighting are modified to achieve the different targets of attack. Even though the tactics of attack and defense appear more adult-like with increasing age, the playful targets persist well into adulthood.     

Analysis of the targets and tactics of conspecific attack and predatory attack in northern grasshopper mice onychomys leucogaster

Comparisons of tactics of fighting between species are often difficult to make since the body targets attacked may differ. Thus it becomes difficult to assess whether differences in fighting tactics are due to species-specific differences in the tactics themselves or due to the different targets attacked. A solution to this problem is to analyse the tactics of a species that attacks different targets under different circumstances. In this way, differences in tactics can be more readily attributed to differences in targets. In this study, resident male northern grasshopper mice (Onychomys leucogaster) were tested against intruding male conspecifics and against laboratory mice (Mus musculus domesticus). Conspecifics were mainly bitten on the lower dorsum, whereas prey were bitten and killed by bites to the nape of the neck. Therefore, it was possible to analyze the tactics of attack by grasshopper mice when attacking different body targets. For example, in order to defend the lower dorsum and the nape, both intruding conspecifics and prey adopted an upright defensive posture. Resident grasshopper mice used the lateral attack tactic to gain access to the lower flanks but not the nape. This illustrates that the lateral attack tactic is not merely a tactic suitable for overcoming the upright defense tactic, but is used in this context only when the target attacked is on the opponent's posterior dorsum. Such withinpecies comparison enables the identification of the contextual rules which govern the use of fighting tactics. © 1992 Wiley-Liss, Inc.     

Relationships between Parental Maltreatment and Adolescents’ School Adjustment: Mediating Roles of Self-Esteem and Peer Attachment

Parental maltreatment of children has been steadily increasing in Korea despite national efforts to curb it. Children and adolescents who experience maltreatment develop psychological and social maladjustment. Therefore, mediating variables alleviating the negative effects of parental maltreatment on child development should be investigated to develop effective intervention programs. We identified the direct effects of parental abuse and neglect on adolescents’ school adjustment and the mediating effects of adolescents’ self-esteem and peer attachment on the relationships between parental abuse and neglect and their school adjustment. We used data from 2351 middle school students who participated in the Korean Children and Youth Panel Survey. Structural equation modeling revealed the following: child neglect directly and negatively related with adolescents’ school adjustment, whereas child abuse did not. Further, while adolescents’ self-esteem and peer attachment mediated the relationship between child neglect and school adjustment, adolescents’ self-esteem alone mediated the relationship between child abuse and school adjustment. These findings imply that there is a need to develop different intervention programs based on child maltreatment types. Finally, we suggested that the negative effects of parental neglect on adolescents’ school adjustment could be alleviated by adolescents’ self-esteem recovery resulting from peer support. On the other hand, in the case of adolescents experiencing parental abuse, self-esteem recovery through education and counseling provided by teachers or respected adults could be prioritized.     

Supine defense in the intraspecific fighting of male house mice mus domesticus

House mice have been reported rarely to perform the supine behavior pattern as a defensive tactic during intraspecific fighting. However, in this study of intraspecific fighting by male mice, it is shown that mice do indeed rotate to supine. This maneuver is used to evade or extricate themselves from bites to the lower dorsum by the attacking opponent. Once free from the bite the defender does not remain supine, but will immediately turn to prone and flee. Remaining motionless in the supine position may serve a submissive function in other species, but this does not seem to be the case for mice. The present findings illustrate that the supine tactic is a dynamic maneuver for defense of body areas targeted by the opponent. © 1992 Wiley-Liss, Inc.     

Counting the Faithful: Measuring Local Religious Contexts in the United States

This study compares the estimates of religious composition of counties in the United States from three independent datasets: the 2010 Religious Congregational Membership Study (RCMS); the 2010 Infogroup Congregational membership data (INFO); and the Gallup Daily Poll—a large national survey with more than 1.3 million respondents. My analyses suggest that the estimates for most major religious groups from the three datasets are highly correlated to each other. In addition, the measures of local religious compositions from the three datasets successfully predict the religious composition of friendship networks in a large, nationally representative survey. These findings suggest that RCMS, the most widely used data source for measuring local religious composition in the United States, has a convergent and predictive validity. My analyses, however, also highlight important challenges in measuring geographic distributions of non‐Christian populations, as well as total religious populations in all religious traditions.     

Model of Social Competence in an Early Childhood Environment

Maintaining relationships and interacting socially are essential aspects of children's occupational performance. A Model of Social Competence in an Early Childhood environment has been formulated to guide the assessment of and intervention for young children with issues in social skills. This article aims to (1) present the constructs that contribute to social competence for young children, (2) describe the interrelated contextual, foundation and environmental influences on social competence using the Model of Social Competence in an Early Childhood environment as a means of systematically examining these factors, and (3) discuss future directions for early intervention for children with social competence concerns. Cultural considerations will be discussed in relation to the Singaporean early childhood context.     

Learning Related and Interpersonal Social Skills Constructs in Two Existing Social Skills Assessments

In the social skills literature it has been identified that both learning related social skills and interpersonal social skills may exist. This study ascertained the views of 16 experts regarding the existence of the two proposed constructs, learning related social skills and interpersonal social skills, within two pre-existing assessments: Preschool and Kindergarten Behavior Scales–2nd edition and Child Behavior Rating Scale. Sixteen experts from Australia (n = 11) and Singapore (n = 5) with pediatric backgrounds in occupational therapy, speech pathology, psychology and early childhood education took part in the study. Experts were asked to sort cards with each of the items from the Child Behavior Rating Scale and Preschool and Kindergarten Behavior Scales–2nd edition (66 items in total) into one of two piles (one for learning related social skills and one for interpersonal social skills) and then answered several open ended questions about the clinical utility of these constructs. Preliminary evidence demonstrated the existence of the learning related social skills and interpersonal social skills constructs within the items of the two assessments (Child Behavior Rating Scale and Preschool and Kindergarten Behavior Scales–2nd edition). The experts' opinion also suggested the potential clinical benefits of assessing both learning related social skills and interpersonal social skills in preschool-age children. The study results and implications for further research and clinical practice are discussed.     

The Return of the Native: Globalization and the Adaptive Responses of Transmigrants

The intent of this study is to examine the adaptive responses of Hong Kong transmigrants and their transnational and transcultural practices in terms of their consequent behavioral and emotional patterns. Their transnational practices and relative adaptability can be explained with Robert Merton's (1957) “strain theory.” More specifically, the study aims to identify, describe, and explain the variety of behavioral patterns and modes of emotional manifestations of adaptation of Hong Kong returnees, and to identify their individual and collective strategies of adaptation to help them solve their adjustment and integration problems in their adopted countries.
