Counts of granulocytes were performed on thymic imprints from normal rabbits 3 days old, 2–3 weeks old, and young adults, and from young adult rabbits mildly and severely parasitized with coccidiosis. Analyses of percentages of eosinophils, heterophils, and basophils indicated no sex differences. Comparisons of relative numbers of granulocytes in normal rabbits showed that young adult rabbits possessed more eosinophils and fewer basophils than the younger groups (no differences in heterophils); 3-day-old rabbits had more eosinophils than the 2-to 3-week animals (no differences in heterophils and basophils). No differences in relative numbers of the various granulocytes were found in the mildly and severely parasitized rabbits, but there was a decrease in eosinophils in the parasitized rabbits when compared with the young normal adult rabbits. Eosinophilic leukocytes were divided into two groups: the mononuclear "tissue" line and the lobated "blood" line of development. In the 3-day-old rabbits about 95% of eosinophils were of the lobed variety but in the older normal rabbits, the two developmental lines were about equal in numbers. When compared with the normal young adult rabbits, parasitized rabbits have increased percentages of "blood" eosinophils as a result of greater numbers of band and polymorphonuclear cells.

Musical Tempo

The purpose of this study was to determine the effect of the musical tempo on heart rate (HR), rating of perceived exertion (RPE), and distance run (DR) during a treadmill aerobic test in young male and female adults. Participants ran on the treadmill listening to music at 140 beats per minute (bpm; M140), 120 bpm (M120), or without music (NM). No significant sex differences were found on HR (M140 = 172.6 ± 12.7, M120 = 171.9 ± 11.1, NM = 170.1 ± 12.2 bpm, p = .312), RPE (M140 = 7.5 ± 1.4, M120 = 7.6 ± 1.3, NM = 7.6 ± 1.2, p = .931), or DR (M140 = 4,791.4 ± 2,681.1, M120 = 4,900.0 ± 2,916.9, NM = 4,356.1 ± 2,571.2 m, p = .715). Differences were found in the effect of tempo on HR between condition M140 and NM (172.6 ± 12.7 vs. 170.1 ± 12.2 bpm, p = .044, η2 = 0.32). In conclusion, musical tempo does not affect performance, physiological, or perceptual variables in young adults exercising on a treadmill at a constant speed.

Women’S Perceptions

This study sought to describe the system of beliefs on gender, attitudes toward women, and wife beating, in young adults who live in Mysore, India. Furthermore, it identified structural sex differences in the interplay of values among these matters that can affect individual and community views toward domestic violence. Drawing from survey data gathered from 265 young adult Indian men and women, this study used network analysis to graph a correlation network of beliefs and attitudes toward domestic violence. Node, scale, and network structure descriptions allowed for comparisons among male and female participant responses. The findings support the assertion that there are sex differences among the system of beliefs toward wife beating among Indian young adults. Gender ideology, masculine role in relationships, and legal and social consequences of wife beating emerged as the most important values to focus on when addressing young men’s beliefs of domestic violence and attitudes toward women. In contrast, values influencing women’s perceptions of domestic violence are more complex and related to multiple beliefs about women’s power, family structure, and social and legal implications of domestic violence. The results highlight the importance of recognizing gender differences in the connectivity between gender and wife beating beliefs when designing interventions. There is a need for efforts to accurately target these values and attitudes to more effectively address gendered attitudes and beliefs about domestic violence in this population.

Color Preferences

The purpose of the study was to assess differences in color preferences between the sexes. A sample of 193 retirees were asked to report their favorite colors. The pattern of frequencies for preferred color differed as a function of sex. Blue was chosen as the most preferred color by both sexes. Women preferred black and purple more than men did. Moreover, the men preferred red over pink, whereas the women preferred red and pink equally. The rank order of color preferences for this elderly group were very similar to the findings of Silver, et al. who sampled young adults in 1988.
