Leisure Education and the Family
Having and utilizing free time is often a problem for individuals and for families. Family leisure education, focusing on lifestyles and leisure, or family wellness and the role of leisure may be a first step in addressing that problem. No other profession is specifically charged with the responsibility of educating for leisure; that charge is unique to the recreation and leisure profession. Families, as individuals and as a unit have significant time available for experiencing recreation and leisure, and their choices singularly and collectively impact on the unit as a whole. By exploring the components of leisure education, especially self and leisure awareness, the professional has an opportunity to assist family members in exploring intra and interpersonal transactions. Since most of the time families spend is off-work time, their primary interactions take place in the home and during free time, and it is during these times that they will come to know each other and come to bond or fragment as a group. The recreation and leisure choices made by each member and the group impact on how the unit will come to be defined. By exploring values, attitudes, behaviors and roles, the professional can help facilitate the meaning of recreation and leisure in the lives of the family unit. This paper focuses on the conceptual and practical design of a family leisure education model that can be used in various recreation settings including those settings which serve people with disabilities

A novel non-Fermi-liquid state in the iron-pnictide FeCrAs
We report transport and thermodynamic properties of stoichiometric single
crystals of the hexagonal iron-pnictide FeCrAs. The in-plane resistivity shows
an unusual "non-metallic" dependence on temperature T, rising continuously with
decreasing T from ~ 800 K to below 100 mK. The c-axis resistivity is similar,
except for a sharp drop upon entry into an antiferromagnetic state at T_N 125
K. Below 10 K the resistivity follows a non-Fermi-liquid power law, rho(T) =
rho_0 - AT^x with x<1, while the specific heat shows Fermi liquid behaviour
with a large Sommerfeld coefficient, gamma ~ 30 mJ/mol K^2. The high
temperature properties are reminiscent of those of the parent compounds of the
new layered iron-pnictide superconductors, however the T -> 0 properties
suggest a new class of non-Fermi liquid.Comment: 6 pages, 4 figure
Releases and first recovery of Lathrolestes ensator (Hymenoptera: Ichneumonidae) in North America, a parasitoid of Hoplocampa testudinea (Hymenoptera: Tenthredinidae)
The European apple sawfly, Hoplocampa testudinea (Klug), is a pest of apple, Malus pumila Bork. (Rosaceae), in orchards. Introduced from Europe onto Long Island, New York, in 1939, it gradually invaded the New England states (Pyenson 1943). Downes and Andison (1942) also reported the apple sawfly on Vancouver Island in 1940. In 1979, H. testudinea was discovered for the first time in southern Quebec (Paradis 1980), after which it spread throughout the apple-growing areas of this province (Vincent and Mailloux 1988). There are no published records on any natural enemies of H. testudinea in North Americ
Socialization of adolescents’ weight-related behaviors: the roles of best friend and group contagion and adolescent popularity
This study examined two peer relations concepts that may be relevant for understanding weight-related behaviors in adolescents: socialization and popularity. Data from 582 youth in grades 6-8 at an initial time point were used to examine best friend and friendship group socialization of weight-related behaviors, as well as the reciprocal effects of popularity on weight-related behaviors. Measures were administered at two time points and included self-report indices of body dissatisfaction, body-related cognitions, and dieting practices. Sociometric assessments were conducted to examine friendships and two forms of popularity (i.e., preference- and reputation-based). Results suggested that both best friend and friendship group socialization were important predictors of body dissatisfaction, muscle-gaining behaviors, and diet-based exercise, and that gender moderated these processes. Popularity was both an outcome and predictor of weight-related behaviors, and moderated best friend socialization of diet-based exercise. Overall, results were modest and suggest complex processes in peer socialization of weight-related behaviors
Potential mechanisms of peer influence on adolescent girls' disordered eating behavior: an experimental design
This study used an experimental paradigm to examine two factors that may influence the socialization process of peer influence on adolescent females' vulnerability to engage in disordered eating behavior: body-related social comparison and desire to emulate a popular prototype. In the first phase of this study, data were collected to establish local body and dieting norms, as well as to construct study manipulations. In the second phase of the study, subjects participating in the experimental portion were randomly assigned to one of three experimental conditions in which they were exposed to maladpative eating norms by ostensible female peers who were either: 1) thin and of popular peer status; 2) thin and of average peer status; or 3) heavy and of average peer status. Hypotheses were partially supported. Differences emerged in response patterns between 9th and 10th grade participants. Ninth grade participants generally experienced peer influence of disordered eating behaviors. Tenth grade participants, however, did not appear to experience peer influence of disordered eating behaviors. An interaction between body mass index (BMI) and grade was observed such that 9th graders with lower BMI responded significantly more maldaptively in the experimental condition than 10th graders with lower BMI. Results suggest body size was most salient to 9th grade participants' peer influence vulnerability. Peer-led interventions may be particularly effective, but should be tailored to norms within the specific peer context
Beyond a "woman's problem" : the role of relationship processes in female genital pain
Female genital pain is a prevalent condition that can disrupt the psychosexual and relational well-being of affected women and their romantic partners. Despite the intimate context in which the pain can be elicited (i.e., during sexual intercourse), interpersonal correlates of genital pain and sexuality have not been widely studied in comparison to other psychosocial factors. This review describes several prevailing theoretical models explaining the role of the partner in female genital pain: the operant learning model, cognitive-behavioral and communal coping models, and intimacy models. The review includes a discussion of empirical research on the interpersonal and partner correlates of female genital pain and the impact of genital pain on partners’ psychosexual adjustment. Together, this research highlights a potential reciprocal interaction between both partners’ experiences of female genital pain. The direction of future theoretical, methodological, and clinical research is discussed with regard to the potential to enhance understanding of the highly interpersonal context of female genital pai
Inhibition of Rho kinase regulates specification of early differentiation events in P19 embryonal carcinoma stem cells
Background: The Rho kinase pathway plays a key role in many early cell/tissue determination events that take place in embryogenesis. Rho and its downstream effector Rho kinase (ROCK) play pivotal roles in cell migration, apoptosis (membrane blebbing), cell proliferation/cell cycle, cell-cell adhesion and gene regulation. We and others have previously demonstrated that inhibition of ROCK blocks endoderm differentiation in embryonal carcinoma stem cells, however, the effect of ROCK inhibition on mesoderm and ectoderm specification has not been fully examined. In this study, the role of ROCK within the specification and differentiation of all three germ layers was examined. Methodology/Principal Findings: P19 cells were treated with the specific ROCK inhibitor Y-27623, and increase in differentiation efficiency into neuro-ectodermal and mesodermal lineages was observed. However, as expected a dramatic decrease in early endodermal markers was observed when ROCK was inhibited. Interestingly, within these ROCK-inhibited RA treated cultures, increased levels of mesodermal or ectodermal markers were not observed, instead it was found that the pluripotent markers SSEA-1 and Oct-4 remained up-regulated similar to that seen in undifferentiated cultures. Using standard and widely accepted methods for reproducible P19 differentiation into all three germ layers, an enhancement of mesoderm and ectoderm differentiation with a concurrent loss of endoderm lineage specification was observed with Y-27632 treatment. Evidence would suggest that this effect is in part mediated through TGF-β and SMAD signaling as ROCK-inhibited cells displayed aberrant SMAD activation and did not return to a \u27ground\u27 state after the inhibition had been removed. Conclusions/Significance: Given this data and the fact that only a partial rescue of normal differentiation capacity occurred when ROCK inhibition was alleviated, the effect of ROCK inhibition on the differentiation capacity of pluripotent cell populations should be further examined to elucidate the role of the Rho-ROCK pathway in early cellular \u27fate\u27 decision making processes. © 2011 Krawetz et al
TEMPERATURE-DEPENDENCE OF DOMAIN-WALL COERCIVE FIELD IN MAGNETIC GARNET-FILMS
The coercive properties of magnetically uniaxial liquid-phase epitaxy garnet films were investigated between 10 K and the Neel temperature (T(N) less-than-or-equal-to 500 K). Two independent methods, the results of which are nearly identical (magnetical response of oscillating domain walls and the method of coercive loops measured in a vibrating sample magnetometer), were used. Besides the usual domain-wall coercive field, H(dw), the critical coercive pressure, p(dw), was also introduced as it describes in a direct way the interactions of the domain walls with the wall-pinning traps. Both H(dw) and p(dw) were found to increase exponentially with decreasing temperature. Three different types of wall-pinning traps were identified in the sample and their strength, their rate of change with temperature, and their temperature range of activity were determined
