In the article, on the basis of the previous metric characteristics of craniofacial structures using methods of Ricketts R. M., Burstone C. J. and Harvold E. P. in Ukrainian young men and women with orthognathic bite, the features of the cephalometric profile of Ukrainian young men and women were analyzed in comparison with the values of analogical indices of the data determined by the authors of these techniques on residents of other populations and ethnic groups. The established features of the cephalometric characteristics of the juvenile Ukrainian population confirm the need for the creation and further study of normative cephalometric data for various ethnic, age and gender groups of the population.

This chapter describes how American bloggers and Chinese bloggers from similar age and gender groups represent themselves and their identities linguistically in their blogs and explores whether and to what extent the differences in terms of the blogging language and culture affect these representations. The author adopts a corpus-based approach and focuses on the description and the comparison of the orthographic features and semantic domain preference as revealed in the blog entries. By conducting a cross-linguistic and cross-cultural comparison between American bloggers and Chinese bloggers, the author finds that bloggers’ linguistic practice is closely related to their developmental stage of life, their gender, and the cultural environment they are immersed in. Meanwhile, bloggers’ linguistic practice is also constrained by the internal system of the language they use for blogging.

As the changing demographics of the workplace influence how organizations operate, the need to reexamine relationships between these demographic variables and their effect on the organization continues. This study provides an empirical examination of the effect of two demographic variables, age and gender, and any moderating impact anxiety, enjoyment, and/or peer pressure may have on computer usage. Based on our analysis of 292 knowledge workers, we identified no significant difference between men and women and/or young and old regarding their computer usage in the workplace. Therefore, the findings from this study do not seem to support earlier research regarding age and gender, which indicated that these variables did impact computer usage. However, the moderating construct (anxiety) did appear to be significant in the employees’ computer usage.

The purpose of this chapter is to analyze the physical aerobic work in terms of the metabolic expenditure and compare it with the recommended boundaries of energy found in literature, proposing an alternative to the potential work overload through a compensatory equation introduced in the standard time of the workstation. To support the study, information considering the estimated metabolic expenditure in workers was applied to a novel procedure to reduce the metabolic demand of the task according to age and gender. Results of the study indicated that women older than 30 years exceeded the energy limits from moderate to very heavy load activities, and men older than 40 years exceeded the energy limits in heavy and very heavy workloads. The proposal of compensatory equation statistically reduced the energy loads below the recommended limits of energy. The aerobic workload is a sensitive factor for age and gender groups and can be potential risks for developing cardiovascular diseases as well as some musculoskeletal disorders.

OBJECTIVE: To examine sex differences in alcohol consumption according to age groups, and to assess gender and age effects on several aspects of alcohol consumption patterns. METHOD: Based on a Brazilian nationwide representative sample (n = 3,007), we analysed the differences in drinking patterns between genders. We also assessed the effects of gender, age, and gender by age interaction for alcohol consumption dimensions (frequent drinking, usual intake, binge drinking, and frequent binge drinking), using logistic and negative binomial regression models. RESULTS: Gender, age, and gender by age interaction had significant effects on the predictive models for all studied drinking patterns, except for the 'usual' dosage. The effect of gender on drinking patterns varies with age. While gender has a greater effect in older age groups, the difference between men and women decreased in the younger age groups. CONCLUSIONS: Gender convergence regarding alcohol use is a trend that might be influenced by environmental factors and should be addressed in prevention and treatment programs, as well as in public health policies.

The roles chronological age and gender play in subjective time experience were explored in a sample of 294 adult men and women. Subjective time experience (STE: the difference between subjective age and chronological age) was found to vary widely among individuals, with some being “accurate” (SA = CA), and others either “retarded” (SA < CA) or “advanced” (SA > CA). Males were more retarded in STE than females at every point in the lifespan, and patterns of age differences in adulthood differed for the two sexes as well. The results suggest that chronological age may play a key role in transitions in STE, and that chronological age is more significant in the STE of women than in the STE of men.

To evaluate the influence of age and gender on the neuroendocrine control of blood pressure in normal subjects, a 13-min 70° head-up tilt (HUT) was applied after 3 h of recumbency to 109 healthy men and women aged 23–50 yr ( age group I) and 51–77 yr ( age group II). We found that age and gender had a significant influence on plasma norepinephrine (PNE) concentration at baseline and in the upright position. PNE was significantly higher in older men compared with the younger men and women of both age groups, suggesting a divergent age-related activation of the sympathetic nervous system between genders at baseline as well as during a sustained orthostatic challenge. There was no significant influence of age or gender on plasma epinephrine at baseline or during HUT. Plasma renin activity was significantly higher at baseline as well as in the upright position during HUT in elderly men than in women. Age or gender had no influence on plasma vasopressin (PAVP), and, regardless of age, nonhypotensive HUT induced an extremely modest increase in PAVP. The syncopal subjects displayed a hormonal pattern associating increased PNE and a surge in plasma epinephrine and PAVP minutes before syncope during HUT. The orthostatic intolerance appears not to be a feature of healthy aging per se. In healthy subjects, both age and gender modulate markedly the cardiovascular and neuroendocrine responses to an orthostatic challenge and must be taken into consideration, particularly when catecholamine responses are studied.
