Body Image Perception: Adolescent Boys and Avatar Depiction in Video Games
Research on mass media’s impact on body image has mostly been focused on females thus far. Of the little research that has been done on male body image, most of it has been focused on adult males, and therefore the effect of mass media on adolescent boys’ body image is still a relatively primitive field of knowledge. Through comparing the exposure of adolescent boys to muscular avatars in popular video games, a source of mass media that a majority of adolescent boys are exposed to, and relating it to research done on the effects of frequent ideal image exposure through other forms of mass media on males, the influence of video games on the body image of adolescent boys can be determined. This study consisted of several factors: (1) understanding the impact of constantly viewing ideal images in mass media on males’ perceptions of their own bodies, (2) reviewing the body types of the male avatars in several modern, popular video games played by adolescent boys, (3) relating the exposure of video game avatars on adolescent boys’ views of their own physiques, and (4) examining the implications of negative body image on adolescent boys’ eating and exercise strategies. Although video game avatars tend to have a slightly different body shape than those presented in most types of mass media, their unifying trait of naturally unattainable muscularity resulted a reaction among adolescent boys that was similar to that of adult males with regard to mesomorphic (muscular, V-shaped) body types in mass media. This resulting negative body image can lead to psychological disorders such as depression or such physical disorders as anabolic steroid usage, unnatural dieting, and excessive exercising
Vector bundles with a fixed determinant on an irreducible nodal curve
Let be the moduli space of generalized parabolic bundles (GPBs) of rank
and degree on a smooth curve . Let be the closure of
its subset consisting of GPBs with fixed determinant . We define a
moduli functor for which is the coarse moduli scheme. Using the
correspondence between GPBs on and torsion-free sheaves on a nodal curve
of which is a desingularization, we show that can be
regarded as the compactified moduli scheme of vector bundles on with fixed
determinant. We get a natural scheme structure on the closure of the subset
consisting of torsion-free sheaves with a fixed determinant in the moduli space
of torsion-free sheaves on . The relation to Seshadri--Nagaraj conjecture is
studied.Comment: 7 page
A note on Hardy's theorem
Hardy's theorem for the Riemann zeta-function says that it admits
infinitely many complex zeros on the line . In this
note, we give a simple proof of this statement which, to the best of our
knowledge, is new.Comment: 9 pages; To appear in Hardy Ramanujan Journa
Picard groups of the moduli spaces of semistable sheaves I
We compute the Picard group of the moduli space of semistable vector
bundles of rank and degree on an irreducible nodal curve and show
that is locally factorial. We determine the canonical line bundles of

determinant. For rank 2, we compute the Picard group of other strata in the
compactification of .Comment: 16 pages, no figures, no table
Socio-Economic Determinants of School Attendance in India
This paper investigates the socio-economic determinants of school attendance in India, and the possible causes of disadvantage faced by the girl child. Based on Census data for 1981 and 1991, the determinants of inter-district variations in school attendance are explored, separately for boys and girls. A similar analysis is applied to the gender bias in school attendance. The results indicate that school attendance is positively related to school accessibility and parental education, and negatively related to poverty and household size. Interestingly, a positive association emerges between women's labour-force participation and children's school attendance; possible explanations of this pattern are discussed. The gender bias in school attendance declines with school accessibility and parental education, and rises with household size. Panel data analysis based on the random-effects model supports the cross-section findings.
