Judging the differences between women's attractiveness and health: Is there really a difference between judgments made by men and women?

Perceived weight in the face and body size have been shown to be significant predictors of both attractiveness and health. Studies looking at the relationship between attractiveness, perceived health, and perceived weight in faces have found that individuals prefer a lower weight for attractiveness than for apparent health. Here, a group of twenty-four Asian participants were allowed to manipulate the apparent body mass indices (BMIs) of full-length photographs of young Malaysian Chinese women to enhance their perceived healthiness and attractiveness. Results showed that both men and women differentiated between attractiveness and health by preferring a lower BMI for attractiveness than health, suggesting a consistency in the preferred ideal BMI for attractiveness and healthy appearance across both sexes. Results also suggested that BMI provides important cues to judgments of attractive and healthy appearance.     

Why is low waist-to-chest ratio attractive in males? The mediating roles of perceived dominance,fitness, and protection ability

Past research suggests that a lower waist-to-chest ratio (WCR) in men (i.e., narrower waist and broader chest) is viewed as attractive by women. However, little work has directly examined why low WCRs are preferred. The current work merged insights from theory and past research to develop a model examining perceived dominance, fitness, and protection ability as mediators of to WCR-attractiveness relationship. These mediators and their link to both short-term (sexual) and long-term (relational) attractiveness were simultaneously tested by having 151 women rate one of 15 avatars, created from 3D body scans. Men with lower WCR were perceived as more physically dominant, physically fit, and better able to protect loved ones; these characteristics differentially mediated the effect of WCR on short-term, long-term, and general attractiveness ratings. Greater understanding of the judgments women form regarding WCR may yield insights into motivations by men to manipulate their body image.     

Innovative Assessment of Childhood Trauma and Its Link to HIV and Substance Abuse in Post-Incarcerated Women

Women who are incarcerated often report unresolved early life traumas, which research has linked to subsequent HIV and substance abuse risks. This article presents an arts-based counseling technique used with women re-entering society after incarceration. Women were assessed for childhood trauma (i.e. sexual, emotional, and/or physical abuse) in relation to age of onset and frequency of events using an interactive pictorial assessment technique, Healing Me Timeline activity. The technique allowed women to use color-coded graphs in identifying points along a timeline during which traumatic events occurred and to process insights to foster healthy coping strategies. The timeline activity was an innovative and gender-appropriate method for uncovering the nature and extent of women’s trauma and counseling needs. Facilitators used the counseling tool to assist women in processing personal insights and to make referrals to mental health counseling, medical services, and substance use programs.     

Effects of short-term fatigue on biomechanical and physiological aspects of double poling in high-level cross-country skiers

The study aim was to evaluate biomechanical and physiological alterations in double poling technique (DP) after a short-term fatiguing exercise. Eight high-level skiers performed a sub-maximal DP trial (20 km h⁻¹, 1°) before (PRE) and after (POST) a DP test to exhaustion while roller skiing on a treadmill. An integrated analysis of DP technique during PRE and POST included measurement of pole, joint, and centre of mass (COM) kinematics, poling forces, cycle timing, and metabolic parameters. Muscle fatigue in three upper-body muscles was assessed by calculating the Dimitrov’ fatigue index (FI_nms5) of specific electromyographic segments. FI_nms5 tended to increase in the latissimus dorsi and teres major muscles (P = 0.023 and P = 0.030, respectively) across consecutive DP cycles, as did blood lactate concentration (P = 0.001) and rating of perceived exertion (P = 0.005). The changes indicated a state of fatigue during POST and coincided with the reduction in poling force exertion capacity (P = 0.020). Pole, joint and COM kinematics did not differ between PRE and POST (P > 0.050), whereas recovery phase and cycle times were shorter at POST (P < 0.001 and P = 0.001, respectively). Short-term fatigue led to a reduction in poling force exertion capacity and cycle time in high-level skiers, without altering body and pole kinematics.     

The role of body mass index,weight change desires and depressive symptoms in the health-related quality of life of children living in urban disadvantage: Testing mediation models

Objectives: This study was undertaken to ascertain whether or not the body mass index (BMI) of urban disadvantaged children indirectly affects their health-related quality of life (HRQoL) through weight change desires and depressive symptoms and whether such mediation is conditional upon age and gender.

Design: A total of 255 children aged 7–12 years (50% male) were recruited from 7 schools in urban disadvantaged districts in Ireland using consecutive sampling. A prospective longitudinal design was employed whereby children completed, at two time points, the Kidscreen-27, the Children’s Depression Inventory, and the Health Related Behaviour Questionnaire, and had their BMI measured. The analyses involved multiple-, half-longitudinal- and moderated-mediation.

Results: Results showed that the depressive symptoms of children wanting to change their weight may have lead, in large part, to poorer HRQoL (specifically psychological well-being when considering longitudinal data) rather than weight status per se. The mediation effect of weight change desires occurred regardless of age or gender.

Conclusions: Childhood obesity programmes that traditionally focus on the negatives of obesity and the need to control weight may need to take a more positive approach to health and well-being by, for example promoting intuitive eating, an active lifestyle, body acceptance and good mental health.     

Psychometric Properties of the French Version of the Pictorial Scale of Perceived Movement Skill Competence for Young Children (PMSC)

ObjectiveThe objective of this study was to examine the psychometric properties of a French version of the pictorial scale of Perceived Movement Skill Competence for Young Children (PMSC), which is aligned with the third version of the Test of Gross Motor Development.MethodA sample of 219 French-speaking Canadian children (5 to 12 years old) participated in this study.ResultsResults supported the factor validity and reliability of a 13-item version of the PMSC encompassing two factors (i.e., ball skills and locomotor skills). Subsequent analyses supported the weak, partial strong, and partial strict invariance of responses to the PMSC as a function of sex. Additionally, analyses revealed that boys displayed significantly higher perceived ball skill competence than girls. Results also supported a lack of differential item functioning (DIF) and latent mean differences as a function of body mass index and physical activity/sport involvement, but revealed evidence of DIF and latent mean differences as a function of age. More precisely, these results show that older children displayed significantly: (a) higher scores on the sliding item and lower scores on the kicking item relative to younger children; and (b) lower scores on perceived locomotor skills competence than younger children.ConclusionOverall, results suggest that the French version of the PMSC has acceptable psychometric properties and can be confidently used in research or practice to assess children's perceived movement skill competence.     

Weighing in on risk factors for body dissatisfaction: a one-year prospective study of middle-adolescent girls

Body dissatisfaction is a common problem among adolescent girls that is linked to serious outcomes, including the development of eating disorders. This study tested to what degree five theorized risk factors (weight-related teasing, thin-ideal internalization, body mass index [BMI], self-esteem, and perfectionism) predicted prospective changes in body dissatisfaction. At baseline, 393 10th and 11th grade girls (M = 15.8 years) completed questionnaires and had their height and weight measured. One year later, 316 participants’ body dissatisfaction was reassessed (80.4% retention). Results suggested that self-esteem was the most potent risk factor, followed by BMI, when used to categorize girls into high- and low-risk groups for body dissatisfaction at follow-up. However, weight-related teasing, thin-ideal internalization, and perfectionism did not prove to be risk factors. These results suggest self-esteem and BMI are relevant variables for helping to identify middle-adolescent girls who may be at risk for subsequent increases in body dissatisfaction.     

Density evolution during the growth of disc-shaped aluminium nanoparticles on a liquid surface

Aluminium (Al) nanoparticles (NPs) have been successfully fabricated on a liquid surface by thermal evaporation at room temperature. The Al NPs exhibit a disc-shaped morphology with mean diameter and height in the ranges 20–35 and 1.3–3.7?nm, respectively. As the nominal film thickness increases from 0.02 to 0.18?nm, the mean diameter and height are nearly independent of the thickness, implying that the density of the NPs increases during their growth. An explanation for this phenomenon is presented.     

Do commodities reproduce themselves through human beings? Toward an ecology of goods

The argument of this paper—'an ecology of goods'—could be summarized as follows: Goods exist only in relation to each other. Goods form groups, and in time higher organizational levels, groups of groups, i.e. networks of artifacts emerge. Mass consumption society is the most developed manifestation of this organizing process. The process of association and dissociation of goods is only partly controllable through human decisions. Human beings making decisions about buying, using and disposing of goods are constrained by the “logic” of the general organizing process. This process emerges out of different kinds interactions between commodities and feedback cycles with unintended consequences. In routinization and institutionalization processes commodity interactions become stabilized, i.e. the fidelity of replicative cycles increases. From this perspective, a system of commodities could be seen as an entity, which reproduces itself in a continuous resource exchange with its co‐actors and environment. In a system there is both a tendency toward functional differentiation and integration with other systems. Accordingly, systems of goods are cyclic processes within processes rather than given stable entities. This approach places many theoretical and practical problems of consumer society in a new perspective.
