This study was conducted to compare three different methods for calculating scrotal circumference (ASC1, ASC2, ASC3) adjusted to 365 days of age in Charolais, Limousin and Hungarian Fleckvieh young bulls at the end of the self-performance test. Young breeding bulls from three Charolais, Limousin and Hungarian Fleckvieh breeding farms (farm A: n = 40; farm B: n = 9; farm C: n = 11) were used. The young bulls were kept in loose housing system, in small groups, and fed a diet based on maize silage and concentrate. The scrotal circumference of young bulls was measured at the widest part of the scrotum at the beginning and at the end of the test. Significant growth was observed (+13.6 cm; +8.9 cm; +10.5 cm, P < 0.001) in scrotal circumference (SC) for all breeds except the Hungarian Fleckvieh (ASC2-ASC3: 37.5 vs. 37.6 cm). All differences among the means of the measured and adjusted SCs were statistically confirmed at the P < 0.05 level of significance. A moderate to close positive correlation (r = 0.49-0.99) was calculated among the measured SC and the three types of ASC. The results suggest that method I (ASC1) and method II (ASC2) should be used by the breeders for adjusting scrotal circumferences in the practice.

Two experiments are reported that investigate the mediational role of social influence in the self-perception of exertion. In Experiment 1, subjects performed three 15-min trials on a cycle ergometer at 25%, 50%, and 75% VO2max, both in the presence of another performer (a coactor) and alone. The results indicated that subjects reported lower RPEs when performing with another, particularly at the moderate (50%) intensity. In Experiment 2, subjects performed one 15-min trial at 50% of VO2max, both alone and in the presence of another performer (coactor) exhibiting nonverbal "cues" that the work was either extremely easy or extremely difficult. The results indicated that subjects exposed to the low-intensity cue information reported lower RPEs than when performing alone. Mo significant differences were noted for those subjects exposed to the high-intensity cue information. These findings are discussed in terms of a self-presentational analysis. That such effects were evidenced without physiological responses (VO2, VE, HR) accompanying them supports the notion that psychological variables can play a significant role in the self-perception of exertion. These results, however, are limited to untrained individuals exercising at moderate intensities.

The authors examine the mathematical modeling of methods for the coordination of collective action in the self-organization and self-governance mode. It is assumed that members of the collective create aggregate income whose value grows, as each member invests more effort. The goal pursued by each member of the collective is to maximize personal gains. As we established in the first part of the study, the lack of universal interpersonal trust prevents members of a uniform (unstructured) collective from overcoming a non-effective, Nash equilibrium outcome. Alternative options for structuring the collective were considered, such as creating small groups (coalitions) of agents sharing mutual trust within each group. The strategy of such coalition, aimed at maximizing coalitional gains rather than personal, leads to greater investment of effort by each coalition member, which in turn produces greater aggregate gains for the entire collective. We have shown that in order to secure stability of a coalition structure, first, stimuli for each coalition member are needed such that imply redistribution of quasi-rent to their benefit, and second, control must be exercised on the efforts of the agents. As models demonstrate, members of the collective left outside coalitions or forming small coalitions with a low share taken together (in aggregate) gains, have weaker stimuli for investment. The potential of increasing such stimuli and thereby increasing aggregate gains may be furnished by another, stronger hierarchic-shaped structure – provided transactional costs are sufficiently low. In order to realize this potential, entitlements to residual income must be concentrated in the hands of a single largest coalition or a number of largest coalitions, while banning all other members of the collective from receiving such income. The income of each agent is defined by the terms of the stimulating contract. We have proposed a general design of such a stimulating contract, creating all prerequisites for achieving equilibrium outcome, with Pareto-dominates equilibrium outcomes for other collective structuring options.

In an attempt to predict self-disclosure behavior in small groups from a previously administered Self-disclosure Inventory, 68 participants were rated at the end of 20 group sessions on a 9-point scale of self-disclosure (reliability = .69). Inventory score did not predict rated behavior ( r = .13, p < .05). Additional attempts at validation of the inventory are described.

Self-presentation is a social influence tactic in which people engage in communicative efforts to influence the thoughts, feelings, and behaviors of others as related to the self-presenter. Despite theoretical arguments that such efforts comprise an automatic component, the majority of research continues to characterize self-presentation as primarily involving controlled and strategic efforts. This focus is theoretically challenging and empirically problematic; it fosters an exclusionary perspective, leading to a scarcity of research concerning automatic self-presentations. With the current chapter, we examine whether self-presentation involves an automatic cognitive mechanism in which such efforts spontaneously emerge, nonconsciously triggered by cues in the social environment.
