Pets as safe havens and secure bases: The moderating role of pet attachment orientations

We examined the extent to which a pet functions as an attachment figure. In Study 1, 165 pet owners performed a goal exploration task, assessing the number of life goals generated and confidence in goal attainment. In Study 2, 120 pet owners performed a distress-eliciting task while assessing blood pressure. In both studies, participants were divided into three conditions: pet physical presence, pet cognitive presence, and no pet presence. As compared to no pet presence, physical or cognitive pet presence increased the number of life goals generated and self-confidence in goal attainment and reduced blood pressure during the distress-eliciting task. The findings confirm the ability of a pet to provide a safe-haven and a secure-base and the moderating role of attachment insecurities.     

Dielectric and spectrometric investigations of binary mixtures of tetrahydrofuran with propionic acid

The static permittivity (ε_m ) and the permittivity at the high-frequency limit (ε_∞m ) of a binary mixture of propionic acid with tetrahydrofuran (THF) have been determined for different concentrations at temperatures of 303, 308, 313, and 318 K. The data have been used to compute the Kirkwood correlation factor, the excess permittivity, and the excess free-energy of the mixtures. The Kirkwood correlation factor is found to increase with increasing THF concentration. The mixture exhibited positive values of the excess permittivity and negative values of the excess free-energy of mixing, respectively. UV-Vis and FT-IR spectral measurements have also been carried out. The observed bathochromism and hypochromism in the UV-Vis spectra have been explained in terms of complex formation and ordering of dipoles of the complex. The FT-IR spectrum of the mixture shows considerable shifts in the positions of some of the absorption bands, indicating extensive hydrogen bonding between solute and solvent molecules.     

The energetics and interactions of random dislocation walls

Abstract

Regular dislocation walls, where dislocations are spaced equally along the wall direction, are a popular idealization for modelling the arrangement and interactions of excess dislocations in plastic deformation. The assumption of regular walls is motivated by the fact that such walls represent minimum energy arrangements for dislocations of the same sign, and it allows to use the analytically known short-ranged stress fields of such walls for analyzing the structure of plastic boundary layers. In order to critically evaluate the physical robustness of models based on regular walls, we investigate their random counterparts and demonstrate that the energetics and interactions of such non-periodic dislocation arrangements differ completely from the periodic wall arrangements. Implications of our results for the modelling of plastic boundary layers and dislocation-grain boundary interactions are discussed.     

Preference for online social interactions among young people: Direct and indirect effects of emotional intelligence

The social skills model of generalized problematic internet use predicts that individuals who perceive themselves as having low social competencies are at risk to develop a preference for online social interactions (POSI), which, in turn, might lead to compulsive use of Internet communication services. The present study aims to investigate if self-reported emotional intelligence (EI)—interpersonal and intrapersonal abilities—has an effect on POSI levels, and if this effect is mediated by the subjective importance attached to the major controllability (RC) and reduced non-verbal cues (RNVC) of computer mediated communication. 192 high schools and college students were recruited. Results from structural equation modeling show that Intrapersonal EI predicts both RC and RNVC, which, in turn, predicts the level of POSI. A partial mediation effect was found. On the other hand, Interpersonal EI is significantly associated with POSI, but this association cannot be explained by RC and RNVC. Its effect on POSI seems to be either direct or explained by variables not considered in the present study.     

Parental Positive Reinforcement With Deviant Children:

The purpose of this paper is to review data on the effectiveness of parental positive reinforcement with deviant children. Three areas are reviewed: Non-intervention studies, intervention studies, and consumer satisfaction studies. Results from the first two areas suggest that parental positive reinforcement is neither a necessary nor sufficient procedure to produce or maintain changes in deviant behavior. Results from the consumer satisfaction area indiciate that positive reinforcement is viewed by parents as being both an acceptable and a useful procedure. Therapist recognition of the limitations of positive reinforcement is stressed.     

The Prevention of Children's Maladaptive Fears

The authors address the prophylactic value of behavioral techniques in relation to children's maladaptive fears. The major settings of interest from the viewpoint of preventing children's maladaptive fears are the home, school and health-care settings. Encouraging findings have been reported in the use of film-modeling with children about to undergo dental treatment, tonsillectomies, injections, etc. Several theoretical explanations (stimulus pre-exposure, reciprocal inhibition, reinforcement contingencies, self-efficacy) of the success of such interventions can be advanced to affect the outcome of maladaptive fear prevention programs.     

The Primary Care Health System as a Core Resource in Response to Terrorism

Abstract

Living through a terrorist event or under threat of attack affects both mental and physical health. A nation's primary care system plays a critical role under such circumstances. This article reviews the American experience after September 11, 2001 and advocates for integration of mental and physical health services in primary care settings as a key counter-terrorism strategy. Americans put their trust in primary care providers. The nation's healthcare system must develop and implement a strategy that informs and supports primary care providers in meeting the mental health needs of a nation confronted by terrorism.     

Temperament in early childhood and peer interactions in third grade: The role of teacher–child relationships in early elementary grades

Children's interactions with peers in early childhood have been consistently linked to their academic and social outcomes. Although both child and classroom characteristics have been implicated as contributors to children's success, there has been scant research linking child temperament, teacher–child relationship quality, and peer interactions in the same study. The purpose of this study is to examine children's early temperament, rated at preschool age, as a predictor of interactions with peers (i.e., aggression, relational aggression, victimization, and prosociality) in third grade while considering teacher–child relationship quality in kindergarten through second grades as a moderator and mediator of this association. The sample (N = 1364) was drawn from the NICHD Study of Early Child Care and Youth Development. Results from structural equation models indicated that teacher–child conflict in early elementary grades mediated links between children's temperament and later peer interactions. Findings underscore the importance of considering children's temperament traits and teacher–child relationship quality when examining the mechanisms of the development of peer interactions.     

Behavioral Differences between Rabbits and Cats

The sensory modality of a task and the modality of a retroactive interfering activity were systematically covaried in order to test Connolly and Jones' and Pick's translation models of intersensory functioning. Forty 10-year-old boys and girls were asked to recall distance and location cues of length under intrasensory and intersensory task conditions (visual and kinesthetic). Visual and kinesthetic interpolated activities were used in an attempt to provide modality specific interference with the recall of length under the various sensory task conditions. Results of the data analyses provided no support for the Connolly and Jones model of modality specific storage with translation. Rather, the findings of the study were interpreted as supportive of Pick's hypothesis which emphasizes the coding of stimulus information (regardless of modality of input) into a form specific to whatever modality is specialized for detection of the information.     

Winnicott: A research perspective

This paper describes research conducted over the past twenty years that was informed by Winnicott's thinking on the importance for child development of the early mother-infant relationship.
