In the fall of 1942 at the urgent request of the federal government, as an incentive to interest in piloting and navigating airplanes, many of the secondary schools of our country set into operation classes in aerial navigation, aerodynamics and meteorology. The navigation courses were in the main, the responsibility of the teachers of mathematics. They have been preparing youth including a few young women now for three years. The motive of these young folk in selecting the course is either the wish to pilot soon or that of understanding a timely subject. Many of the young men of the earlier classes are flying missions now “down under” in the South Pacific.* Some are flying their own planes from England for furloughs and then new assignments. Now the Army Air Corps is closed to admissions, and moreover, many men classified in that branch of the service for months, “on the line,” awaiting anxiously their transfer to preflight have been notified officially that they will not be needed as pilots or navigators or even bombardiers. One wonders what the effect will be on elections to a high school course in navigation. Will it develop that aerial navigation is an emergency subject, incident to the war, in secondary schools, to vanish from the curriculum in a few years, parts of it to be taken over into the courses in so-called pure mathematics? Or will navigation continue as a course optional in high school? At the moment options are holding up well.

The lack of diversity among patent holders in the United States (1-3) is a topic that is being discussed by federal policymakers. Available data suggests that prolific patent holders and leading technology innovators are 88.3% male and nearly 94.3% Asian, Pacific Islander, or White, and half of the diversity that does exist is among those who are foreign born (3). The data shows that there is a need for greater diversity among patent holders. Few studies, however, are available to guide the work of educators creating learning opportunities to help young people from diverse backgrounds learn to invent. Educators must navigate issues that have complex sociocultural and historical dimensions (4), which shape the ideas of those surrounding them regarding who can invent, with whom, under what conditions, and for what purposes. In this paper, we report the results of an ongoing multimethod study of an invention education pro- gram that has worked with teachers and students in Grades 6 through 12 for the past 16 years. Findings stem from an analysis of end-of-year experience surveys and interview transcripts of six students (three young men and three young women) who participated in high school InvenTeams®. The data were used to investigate three topics: 1) ways high school students who have participated on an InvenTeam conceptualize the term "failure" and what it means to "learn from failure," 2) what supported and constrained the work of the three young women during their InvenTeams experience and the implications for policy makers concerned about the gender gap in patenting, and 3) ways the young men and young women took up (or didn't take up) the identity of "inventor" after working on a team that developed a working prototype of an invention during the previous school year.

This research examines the effect of gender and family resources on success in multiple areas of science. Science experiences are measured using longitudinal science trajectories. Findings show that young women are less likely than young men to persist in science, whether it is science achievement, access, or attitudes. Large numbers of women permanently exit the science pipeline after their sophomore year of high school. However, results from the science trajectory models show that among men and women who are equally qualified, women are not necessarily less likely to persist in science. Results also show that young men have more family resources than young women and some of the total effect of gender on science experiences involves an indirect effect through family resources. In addition, gender interacts with family resources with the effects of many resources being stronger for women than for men.

The gender gap in college enrollment and completion has become a concern in many nations. The phenomenon is extreme in Alaska, particularly among indigenous people. Semi-structured interviews with 162 urban and indigenous students graduating from high school, and in addition, two single-gender focus groups, suggest that many young men do not see a college education as necessary to financial success and do not expect to assume the gender role of sole family provider. Young women tend to see a college degree as essential to changed gender roles where women are expected to attend college, pursue a career, and not be dependent on a man for financial support. Many young men withdraw from the demands of a verbally-saturated high school curriculum, which they find unenjoyable. Both young men and young women tend to label male withdrawal from school as “male laziness,” an essentialist interpretation rather than an interpretation based on the school environment and changing gender roles.

102 schoolchildren of the 9-11th classes of secondary school No. 2 of Stavropol, without genetic pathology, were examined. The functional state of the central nervous system was determined by the method of computer chronoreflexometry; using psychological tests, we determined the level of personality (PA) and situational (SA) anxiety, as well as (and) the level of aggressiveness. It was established that in the 9-11th classes, girls and young women have a higher level of PA and SA than boys and young men (p <0.050.01). During the training the girls’ and boys’ the level of PA remains relatively constant, however, the variability of PA of 17 years-old young women is higher than of the young men. The level of SA of the girls tends to increase throughout the entire period of study in high school, while for boys it rises only the 10th class, and decreases by the beginning of the 11th class. For the indicators of aggression, gender differences begin to appear in the 10th class: aggressiveness index and indirect aggression in the boys’ significantly higher than the girls’ are. In the 11th class, young men significantly increase in comparison with girls an indicator of hostility, verbal aggression and offence (p <0.05).

The extremely high concentration of aggression in society towards people of other nationalities and the lack of an unambiguous and adequate scientific definition of this complex phenomenon make the problem of aggressiveness research one of the most urgent in the modern world. The authors consider four main approaches to the study of aggression, which can be designated as instinctivistic, frustration, behavioristic and cognitive. The article presents the main results of an empirical study in the form of a questionnaire, the respondents of which were high school boys of one of the city's secondary schools.

This article presents the results of a study the purpose of which was research of the factors and patterns of aggression in adolescence. Its results are required to find personas, who need preventive work, and features of the system of preventive measures, depending on the structure of the target audience. In 2016 there were 721 respondents who took part in the study, and 1437 in 2019. The method used in this study is the Buss-Durkee test modified by G. V. Rezapkina (BDHI). Results of the study clearly demonstrate that amongst young people there is a high-level spread of severe irritation, especially among young women. Also, the predominance of such components of aggression as negativity and irritation was noted. According to the results, young women more often get irritated than young men, and on the scale of “negativism”, there is no significant differences. Physical aggression was discovered to be more characteristic for young men.

Customization of mental health therapies needs to consider the differences in degree of brain maturity between young (18–29 years) and mature (30 years or older) adults as well as brain morphology among men and women. The aim of this study was to identify the significant dietary and lifestyle contributors to mental distress in these sub-populations. Independent repeated cross-sectional sampling was performed for over a 5-year period (2014–2019) to collect data from different populations at different time-points and seasons. A backward stepwise regression analysis was used on 2628 records. Mental distress in young women was associated with high consumption of caffeine and fast-food, and it was negatively correlated with moderate-high levels of exercise as well as frequent breakfast consumption. Mature women shared several common factors with young women; however, high fruit consumption was negatively associated with mental distress. For young men, high exercise, moderate consumption of dairy, and moderate-high intake of meat were negatively associated with mental distress. In addition, high fast-food and caffeine consumption were positively associated with mental distress in young men. For mature men, strong negative associations between higher education, moderate intake of nuts and mental distress surfaced. Our results support the need to customize dietary and lifestyle recommendations to improve mental wellbeing.

Introduction: Over 30 million Americans suffer from hearing loss (HL). Studies suggest that established cardiovascular disease (CVD) risk factors may contribute to the pathophysiology of the inner ear. However, the aggregate effect of CVD risk factors on hearing is not well understood. Hypothesis: We hypothesized that high CVD risk burden is associated with worse hearing. Methods: We assessed younger (ages 18-34) and older (ages 55-64) Hispanic Community Health Study / Study of Latinos participants who underwent audiometry in 2008-11. After excluding those with conductive pathology and asymmetric HL, we randomly chose one ear for analysis. Puretone thresholds were obtained at 0.5-8 kHz; puretone average (PTA) was calculated using thresholds at 0.5, 1, 2, and 4 kHz. Low CVD risk burden was defined as having all of: blood pressure (BP) <120/<80 mmHg; total cholesterol <180 mg/dL; not currently smoking; and not having prevalent diabetes. High CVD risk burden was defined as ≥ 2 of: diabetes; currently smoking; BP >160/>100 mmHg (or antihypertensive use); and total cholesterol >240 mg/dL (or statin use). By age group and sex, we estimated hearing thresholds per frequency with linear regression models adjusted for noise exposure. Least squares estimates were calculated using strata-specific means of covariates. Estimates were compared via t-tests. Data were weighted for all analyses and accounted for clustering. Results: Among younger and older individuals in the target population (51.9% female), 28.8% had low and 5.5% had high CVD risk. Younger men with high CVD risk had worse PTA than young men with low risk (7.7 dB HL [7.0-8.4] vs. 10.5 dB HL [8.4-12.5], p =0.02), and had significantly worse thresholds at 1,3,4,6 kHz than those with low risk ( Figure ). There was no difference in PTA or thresholds at any frequency by CVD risk burden in young women, older men, or older women. Conclusions: CVD risk burden is associated with HL among young men, but not young women or older adults. CVD risk burden may be useful for identifying young men at risk for HL.
