Body DissatisfactionThe author concentrates on the preference of the values of "the cult of the body" increasingly affecting the behaviour of young people and their position in the value system relating to generally recognized values. Too much emphasis on physical beauty and outward appearance significantly determines behaviour and can lead to a reduction in values relating to the body and body shape but also to unhealthy eating disorders such as bulimia or anorexia nervosa. The focus is on the pathological perception of the body, on how culture and cultural norms affect body dissatisfaction. A research questionnaire on universal values and the cult of the body (2006) was used. The research sample consisted of 508 respondents aged between 18 and 26 (292 women and 216 men).

Background/Aim. The widespread symptoms of anorexia nervosa (AN) in young women require to draw professional attention to this problem in Serbia. In previous research on AN, insecure attachment styles, perfectionism and concerns about body shape were identified as notable risk factors. The aim of this study was to identify the prevalence of AN among female students and assess the importance of these factors in its development. Methods. The Eating Attitudes Test (EAT-40), the Experiences in Close Relationships Scale (ECR), the Frost Multidimensional Perfectionism Scale (FMPS) and the Body Shape Questionnaire (BSQ) were applied to a sample of 500 randomly selected female students of the University of Belgrade, the mean age of 22.44 years (min 18, max 35). In addition, Body Mass Index (BMI) was also calculated. Results. Although 38 (7.6%) female students displayed symptoms of AN (EAT > 30) and 13 (2.6%) had BMI indicating anorexia nervosa syndrome (BMI ? 17.50 kg/m2), only 1 (0.2%) student fulfilled both criteria. The majority of female students (60.4%) had some type of insecure attachment style. There is a significant influence of attachment styles on symptoms of AN: female students with insecure attachment styles have a significantly higher mean score on the EAT compared to those with secure attachment style (F = 7.873; p < 0.01). There was a positive correlation between scores on the EAT and FMPS (r = 0.217; p < 0.01), and scores on the EAT and BSQ (r = 0.388; p < 0.01). Conclusions. The obtained results show the prevalence of AN of 0.2% among female students and indicate the importance of insecure attachment styles, perfectionism and concern about body shape as risk factors. Activities for the prevention of AN in this subpopulation should include internet-based therapy and special counseling services with specific programs focusing on emotion-regulation skills through mindfulness, acceptance and commitment techniques, as well as specific cognitive-behavioral techniques.

Heavier bodies—particularly female bodies—are stigmatized. Such fat stigma is pervasive, painful to experience, and may even facilitate weight gain, thereby perpetuating the obesity-stigma cycle. Leveraging research on functionally distinct forms of fat (deposited on different parts of the body), we propose that body shape plays an important but largely underappreciated role in fat stigma, above and beyond fat amount. Across three samples varying in participant ethnicity (White and Black Americans) and nation (U.S., India), patterns of fat stigma reveal that, as hypothesized, participants differently stigmatized equally-overweight or -obese female targets as a function of target shape, sometimes even more strongly stigmatizing targets with less rather than more body mass. Such findings suggest value in updating our understanding of fat stigma to include body shape and in querying a predominating, but often implicit, theoretical assumption that people simply view all fat as bad (and more fat as worse).

The model of body–vortex interactions, where the fluid flow is planar, ideal and unbounded, and the vortex is a point vortex, is studied. The body may have a constant circulation around it. The governing equations for the general case of a freely moving body of arbitrary shape and mass density and an arbitrary number of point vortices are presented. The case of a body and a single vortex is then investigated numerically in detail. In this paper, the body is a homogeneous, elliptical cylinder. For large body–vortex separations, the system behaves much like a vortex pair regardless of body shape. The case of a circle is integrable. As the body is made slightly elliptic, a chaotic region grows from an unstable relative equilibrium of the circle-vortex case. The case of a cylindrical body of any shape moving in fluid otherwise at rest is also integrable. A second transition to chaos arises from the limit between rocking and tumbling motion of the body known in this case. In both instances, the chaos may be detected both in the body motion and in the vortex motion. The effect of increasing body mass at a fixed body shape is to damp the chaos.

AbstractIntertidal sea stars often function in environments with extreme hydrodynamic loads that can compromise their ability to remain attached to surfaces. While behavioral responses such as burrowing into sand or sheltering in rock crevices can help minimize hydrodynamic loads, previous work shows that sea stars also alter body shape in response to flow conditions. This morphological plasticity suggests that sea star body shape may play an important hydrodynamic role. In this study, we measured the fluid forces acting on surface-mounted sea star and spherical dome models in water channel tests. All sea star models created downforce, i.e., the fluid pushed the body towards the surface. In contrast, the spherical dome generated lift. We also used Particle Image Velocimetry (PIV) to measure the midplane flow field around the models. Control volume analyses based on the PIV data show that downforce arises because the sea star bodies serve as ramps that divert fluid away from the surface. These observations are further rationalized using force predictions and flow visualizations from numerical simulations. The discovery of downforce generation could explain why sea stars are shaped as they are: the pentaradial geometry aids attachment to surfaces in the presence of high hydrodynamic loads.
