Cortisol concentrations in hair collected from young male and female adults were assayed and compared for differences along shaft length and between body sites. No significant differences were found between hair shaft sites, supporting a model of the hair shaft as “alive” and responsive to environmental demand in terms of cortisol production. Hair taken from forearms had significantly higher concentrations of cortisol than hair from lower legs, suggesting a localized hair cortisol response and verifying previous findings. Issues of the link between central and peripheral HPA axes are raised for discussion and further investigation.

Hair Cortisol

Human-caused landscape change negatively affects the sustainability of many wildlife populations. In Alberta, Canada, grizzly bears ( Ursus arctos L., 1758) live in one of the most populated and heavily exploited landscapes in which the species survives. Long-term physiological stress in individual animals may be the predominant mechanism linking landscape change with impaired wildlife population health. Hair cortisol concentration has been validated as a biomarker of long-term stress in humans and domestic animals; however, limited work has examined factors that may affect its measurement or interpretation. We have measured cortisol in as few as five guard hairs of a grizzly bear and have identified factors influencing hair cortisol concentration in this species. Hair cortisol varies with hair type, body region, and capture method. It is not influenced by colour, age, sex, environmental exposure (18 days), or prolonged laboratory storage (>1 year) and does not vary along the length of the hair shaft. Recommendations for prudent use of hair cortisol analysis in grizzly bears are discussed with implications for the development of hair cortisol concentration as a tool to monitor long-term stress in other wildlife.

This study aimed to examine inter-limb jump asymmetries and their association with sport-specific performance in young swimmers. Thirty-eight (male, n = 19; female, n = 19) regional/national level young swimmers (age: 12.3 ± 1.2 years; height: 159.6 ± 8.2 cm; body mass: 52.5 ± 9.2 kg) participated in this study. Inter-limb asymmetries were assessed for single-leg countermovement jump (SLCMJ) and single-leg standing long jump (SLSLJ). Sport-specific performance was evaluated using front crawl (i.e., 50 m and 25 m) and front crawl kick (i.e., 50 m and 25 m). The kappa coefficient revealed a “slight” level of agreement (Κ = 0.156, 0.184, and 0.197 for female, male, and all, respectively) between the direction of asymmetry for SLCMJ and SLSLJ, indicating that asymmetries rarely favored the same limb during both tests. A paired sample t-test showed a significant difference (p = 0.025) between asymmetry scores obtained in SLCMJ and SLSLJ. No significant difference was found in asymmetry scores between males and females (p = 0.099 to 0.977). Additionally, no association between asymmetry scores and sport-specific performance was observed (p > 0.05). Our findings highlight the independent nature of inter-limb asymmetries derived from SLCMJ and SLSLJ among young male and female swimmers. Further, our results suggest no association between jumping asymmetries and sport-specific performance.

Stalking Victimization

Most stalking studies are conducted in the West. Limited information is available on victims of stalking from the Asian continent. This study specifically explored the victimization experiences of young male and female adults in Hong Kong. Using a large sample of university students ( N = 2,496) aged between 18 and 40 years, the gender distribution of stalking incident characteristics was examined, along with prevalence of various stalking behaviors, and victim–offender relationships by types of stalking behaviors. The differential role of demographic and psychosocial characteristics in stalking victimization experience was also explored. The lifetime prevalence rate of stalking victimization was 8.2%, with a higher estimate in females than males (11.6% vs. 3.8%). The sample analyzed in this study was 196 stalking victims. Although surveillance-oriented behaviors were most frequently reported by both males and females, significant gender differences in types of stalking behaviors were noted. Multivariate analyses indicated that increases in age and levels of self-esteem were correlated with an increased probability of experiencing stalking victimization, while being a male and higher levels of life satisfaction were related to a lower likelihood of falling prey to stalking victimization. This study concludes with a call for anti-stalking legislation in Hong Kong given the devastating nature and consequences of stalking victimization.

Does money bring happiness? This study was undertaken to understand and analyze the relationship between materialism and happiness. The sample consists of on young male and female students in the age group of 18-21years belonging to service class family and living in the tri-city of Chandigarh, Panchkula and Mohali. For the purpose of study respondents were selected randomly who were administered the structured questionnaire to measure happiness and materialism using Oxford Happiness questionnaire, Richards and Dawson Materialism Scale. Descriptive analysis, correlations, and t-ratios was applied to the data. Results revealed non- significant relationship between materialism and happiness. Gender difference was also studied.
