The current study involved two experiments which were conducted at the Texas A&M Agricultural Research and Extension Center in Uvalde (semi-arid environment) from 2002 to 2004. In experiment one, Bonsmara bulls (n = 19; 20-24 mo of age) were joined with multiparous, crossbred females (n =586) for 90 d in 2003 and 2004. Bulls were allotted by selected physical traits, seminal traits, social rank, and serving capacity to one of two bull to female ratio (BFR) treatments: Conventional (1:21-1:29; n = 6 pastures) or Low (1:47-1:52; n = 2 pastures) BFR. Pregnancy rate (P = 0.33), calving rate (P = 0.26), and calving date (P = 0.22) did not differ between Conventional and Low BFR treatments. Post-breeding evaluation of bulls in 2002 (n = 16) indicated that social rank, but not seminal traits, was significantly correlated with pre-breeding values (P < 0.05). The current study demonstrates that Low BFR can be utilized in single- and multisire, 90-d breeding pastures of up to 2,090 ha without adversely affecting reproductive performance. In experiment two, yearling, one-half or three-quarter Bonsmara heifers (n = 106; 11-14 mo of age) were palpated per rectum and assigned a reproductive tract score (RTS) immediately prior to the beginning of the breeding season. Reproductive performance was measured in their two subsequent breeding years in order to estimate the value of the RTS system in extensively-managed, natural mating, 90-d breeding season programs. RTS was positively correlated (p < 0.01) with frame score (r = 0.25), age (r = 0.31), weaning weight (r = 0.47), and the weight of the heifer on the day of RTS exam (r = 0.56). The RTS means by dam parity also differed (P < 0.03). A lower (P < 0.01) percentage of females conceived during each of their first two breeding seasons for heifers of RTS 1 and 2 (65.2%) than for heifers of RTS 3, 4, and 5 (91.2%). Females with a RTS of 1 had a lower pregnancy rate over each of their first two breeding seasons, conceived later during their first breeding season, weaned lighter first calves, and remained lighter each year for fall body weight and body condition score than did heifers with RTS of 2 to 5 (P < 0.05). Collectively, the results of the current study indicate that heifers with a RTS of 1 immediately prior to a 90-d breeding season should be culled. Consideration should also be given to eliminating RTS 2 heifers, but further studies will be needed to confirm the potential economic advantage of this practice.

On the working environments of male in majority, female leaders tend to encounter different problems due to gender differences. In the TV program producing process of the modern communications industry, TV Director is the main leader of the whole TV program production teams. However, on the TV program producing setting with males as manipulating power at every step of production and filling with machines and hardware equipment, most of posts acted by females are administrative staff, production assistant, and assistant to TV Director. There are significant differences on the ratio of males to females for the position of TV Director. Does different leadership behavior between males and females cause the differences on the ratio of males and female leaders? After all, on the TV program producing setting with males as manipulating power, what are the leadership characteristics of female TV Director? Do the leadership behaviors of female TV Directors differ from those of male ones? What kinds of difficulties female TV Directors encounter during their leadership? The present study aims to make a survey from the perspective of females and the related disclosure of feminism. The subjects are female TV Directors of Television industries. The in-depth interview research method of the qualitative research is used for the selected female TV Directors, supervisors of female TV Directors and the related staff members to analyze their leadership behaviors and problems.The research finds that: 1. Leading traits of female TV Directors: the spirit of try, carefulness, responsible and openness. 2. Differences between the leading traits of female TV Directors and male TV Directors female TV Directors are careful and pay attention to details while male TV Directors tend to be firm and resolute, subjective, and effective to lead. 3. Leadership behavior of female TV Directors: tend to lead high degree of recognition and high initiating structure. They mainly use democratic leadership style. 4. Female TV Directors tend to lead higher initiating structure than male TV Directors. 5. Female TV Directors tend to use authoritative leadership style when facing problems or the emergency conditions. 6. There are differences of employee-oriented leadership behavior between males and females. 7. Ability is the key factor to breakthroughs gender differences.

This study was to determine if there exists a difference in the rate of hirsutism in genetically similar women in two different environments. 112 Nigerian women living in the U.S.A and 70 women living in Nigeria were surveyed. All women completed a pictorial survey scoring peripheral hair growth in 6 body areas from 0 (no significant hair growth) to 4 (severe hair growth). Total hirsutism score was calculated as a sum of individual scores. The survey also included demographic data, menstrual history, and data regarding use of hormonal treatments. Statistical comparisons between groups included t-test, nonparametric tests and chi-square test. Multiple regression analysis was carried out to identify independent predictors of peripheral hair growth. Women residing in U.S.A had a 31% higher total hirsutism score than those residing in Nigeria. This difference was not related to irregular menstrual cycle. To account for possible effects of age, B.M.I and differences in tribal origin, multiple regression analysis was performed. Location (living in U.S.A vs. Nigeria) remained the strongest predictor of total hirsutism score (P=0.02); tribal origin was also significant (P=0.04), while age and B.M.I had no independent predictive value (P>0.1). It was concluded that this difference, is not explained by factors such as age, obesity and ethnic origin. We propose that this difference may be due to differences in environmental or lifestyle factors of the women.
