Body image, eating disorders, and the drive for muscularity in gay and heterosexual men: the influence of media images

This Internet research project examined the relationship between consumption of muscle and fitness magazines and/or various indices of pornography and body satisfaction in gay and heterosexual men. Participants (N = 101) were asked to complete body satisfaction questionnaires that addressed maladaptive eating attitudes, the drive for muscularity, and social physique anxiety. Participants also completed scales measuring self-esteem, depression, and socially desirable responding. Finally, respondents were asked about their consumption of muscle and fitness magazines and pornography. Results indicated that viewing and purchasing of muscle and fitness magazines correlated positively with levels of body dissatisfaction for both gay and heterosexual men. Pornography exposure was positively correlated with social physique anxiety for gay men. The limitations of this study and directions for future research are outlined.     

Productivity drift in extended learning curves

The pattern of changes in the Extended Learning Curves representing the performance of 114 assembly workers in an electronics firm is examined in terms of changes in productivity drift over long periods of time. It is shown that 2 types of discontinuities can occur. The first consists of a temporary levelling off in productivity followed by a recovery to new higher levels of productivity; the second has a sustained period of negative productivity drift. A number of work facets are statistically tested as possible causes of these patterns of productivity drift, but, the only significant relationship (at P ≤ 0.05 level) is with length of service in job. Some evidence is presented to show that conventional work measurement methods are not effective in terms of assessing the true work output of experienced workers since such workers are able to beat the system by claiming those allowances which are most difficult to cross-check.     

A concept of divorce

The severed strand concept of the process which accompanies dissolution of a marital relationship is presented as an alternative to the busted bond concept. In this theory, emphasis is on the individual and on the importance of retaining the intact strands in a relationship, rather than discarding the whole when one specific strand or strands fail to withstand the strain in the relationship. The impact on self-esteem is emphasized and processes and problems in applying this theory in practice are discussed.     

A production engineering approach to robot selection

The successful introduction of robots into an industrial enterprise means real commitment, engineering support, and detailed involvement in the planning of an integrated manufacturing system. In particular, the production engineer is clearly seen in this context to be the system designer. He must therefore be in a position to specify the performance of all man and machine components within the system such that productivity is maximised. Robot types are reviewed, and analogies between man and machine are used to introduce the RTM concept. Finally, a simple method is given for estimating robot throughput times from elementary velocity profiles. The fall-off in throughput due to the effect of many small robot movements is emphasised.     

An exploration of the drive for muscularity in adolescent boys and girls

Much of the existing research on disordered eating has centered on the drive for thinness, which is most commonly observed in girls and women. The male standard of bodily attractiveness, however, is bigger, bulkier, and more muscular. Are boys and men motivated to be big and muscular in the same way that girls and women are motivated to be thin? The authors constructed a 15-item survey and administered it to 197 adolescents. The findings showed that the drive for muscularity measure displayed good reliability; that individuals high in the drive were more likely to be boys who were trying to gain both weight and muscle mass; that the drive was related to poor self-esteem and higher levels of depression among boys, but not among girls; and that the drive for muscularity was relatively unrelated to the drive for thinness.
