This paper studied the physiological response of the human circulatory system to local cooling of the feet. The research involved young men (n = 27) and women (n = 30) aged between 17 and 20 years, born and permanently living in the Arctic zone of the Russian Federation (Arkhangelsk). SIMONA 111 integrated monitoring system was used. We found that stimulation of peripheral temperature-sensitive receptors of the foot skin at local cooling causes a decrease in heart contractility in both sexes, while young women demonstrate greater sensitivity to the cold factor than young men.

Connecting to the  electronic information network (internet) became the most characteristic that distinguish this era However , the long hours which young men daily spend on the internet On the other hand ,there are many people who are waiting for the chance to talk and convince them with their views This will lead the young people to be part in the project of the “cyber armies “that involved with states and terrorist organizations  This project has been able  to recruitment hundreds of people every day to work in its rank . It is very difficult to control these websites because we can see the terrorist presence in all its forms in the internet   In addition there are many incubation environments that feed in particular the young people minds                                                                                         Because they are suffering from the lack of social justice Also the unemployment, deprivation , social and political repression So , that terrorist organizations can attract young people through the internet by convincing them to their views and ideas . So these organizations will enable to be more  stronger.

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.

Unemployment has a wide range of adverse consequences over and above the effects of the low income which people out of work receive. In the first decades after the war Britain tended to have a lower unemployment rate than most peer countries but this changed in the 1980s and 1990s, when Britain’s unemployment rate surged during the two recessions—possibly as a result of policies designed to tackle inflation. The young, those with less education, and ethnic minorities have higher risks of unemployment and these risks are cumulative. The evidence suggests that the problems facing young men with only low qualifications became relatively worse in the 1990s and 2000s. This perhaps reflects the dark side of educational expansion, young people with low qualifications being left behind and exposed in the labour market.

Abstract Background The system of secure care for young people in England and Wales comprises youth justice, welfare and mental health facilities. Empirical studies have failed to investigate the system as a whole. The National Adolescent Study in 2016 was the first to provide comprehensive system wide information. This paper, derived from that data set, addresses equity of service provision for young men and women in secure care who have mental health problems.MethodsThe detained census population of English young people was 1322 and detailed data were available on 93% of this population, including 983 young men and 290 young women. The descriptive census data were interrogated to identify associations between gender, other sociodemographic and clinical variables, using Chi-square and Fisher’s exact tests. To control for Type 1 errors, the False Discovery rate approach was used. SPSS (V25) was used for statistical analysis.Results Numerically more young men in secure care than young women in secure care warrant a psychiatric diagnosis but young women had a 9 fold increase in the odds of having a diagnosis compared with the young men. The pattern of mental health diagnoses differed significantly by gender as did the pattern of young men and women’s secure care placement. This different pattern of placement continued to differ by gender when the nature of the mental health diagnosis was taken into account.Conclusions No definitive explanation is evident for the significantly different, placement patterns of young men and young women with the same, mental health diagnoses but the anticipated consequences for some, young men and some young women are important. Proper explanation demands an examination of process variables out with the remit of this study. The lack of routine scrutiny and transparent processes across secure settings could be responsible for the development of these differential placement practices; these practices seem at odds with the duty placed on public services by the Equality Act.

Aim. The article deals with determining the features of cerebral energy metabolism in young people at different stages of adaptation in the Arctic region. Materials and methods. The level of permanent brain direct current potentials (DCP) was measured in 146 young people: 93 born and permanently living in the Arctic region and 53 migrants living in new climatic conditions for the first months. The study was conducted by using a “Neuro-KM” 12-channel hardware-software complex for the topographic mapping of brain electrical activity. DCP were recorded in the unipolar leads according to the 10-20 international system. Statistical processing of the data obtained was carried out with the software package SPSS-20 for Windows. Results. In young people permanently living in the Arctic region, we revealed functional asymmetry of the brain with right-hemisphere dominance in almost all leads. In migrants living in the climatic conditions of the Arctic region for the first months, we established high values of energy consumption and partial asymmetry of cerebral energy metabolism. Conclusion. Body functioning in the usual habitat is characterized by a stereotypical set of regulatory mechanisms. During adaptation, new ways of responding to changes in the environment are formed. The dominance of the right or left hemisphere occurs depending on the type of tasks. The analysis of interhemispheric asymmetry of energy consumption performed by using the method of brain mapping allows assessing the degree of dominance. The dominance of energy consumption in the left hemisphere may indicate a possible failure of adaptation mechanisms. Positive interhemispheric gradients indicate the correct performance of CNS regulatory mechanisms during adaptation to new environmental conditions

This paper contributes to the literature by examining gender inequalities in political participation and political engagement among young people from a comparative perspective. By analyzing data on young people from nine European countries collected in 2018, we examine gender inequalities in participation in various modes of conventional and unconventional activism as well as related attitudes, broader political engagement and key determinants, cross-nationally, in order to provide a detailed picture of the current state of gender inequalities in political activism among young people in Europe. Our results allow us to speak to extant theorizing about gender inequalities by showing that the extent of political inequality between young men and women is less marked than one might expect. While the gender gaps in political participation for activities such as confrontational types of protest are small or absent, we find that young women are actually more active in petitioning, buycotting, and volunteering in the community. Young men instead are more active than young women in a majority of the nine countries analysed with respect to more institutional forms of participation linked to organizations and parties, various types of online political participation, and broader political engagement measures, such as internal political efficacy and consumption of political news through various channels. However, young men also appear to be more sceptical at least of certain aspects of democratic practice relative to young women.

Chapter 5 tells the story of Jay, one of several young men that Eric and his group tried to support shortly in his efforts to break free from the criminal justice system. I first met Jay when he was in his early twenties. He was just beginning to construct the kind of narrative and life that would lead him away from the street. Five years after our first meeting, I found myself speaking at Jay’s funeral. This chapter reveals the limitations of buffer-and-bridge work when it comes to changing the life trajectory of young men like Jay and highlights the limitations of the crime-fighting community when it comes to protecting Black youth from violence. The chapter provides a compelling illustration of how and why individualistic efforts at transformation or narrowly focused calls for the redemption of Black men in general and Black fathers in particular – narratives often embraced by a variety of community residents – will always fall short of delivering young people from the various forms of violence that shape their adolescence.

This chapter is devoted to the single life. First it contains a section devoted to the issue of consent: who gives consent for the entry into monastic life, parents or the child? This section is followed by a discussion on single women in monastic and lay environments. The final section is devoted to single men in lay and monastic environments. The majority of single men and women were held hostage by economic circumstances rather than their own agency or choice. The relatively small group of religious young men and women entered their future destination by a combination of parental choice and their own agency. The increase in texts charting the generational battle for consent should be seen firmly in the wider context of a demand for choice amongst young people, especially women.

The effect of prolonged and repetitive cooling of the preoptic/anterior hypothalamic area on the sensitivity to the metabolic effect of noradrenaline and on the resistance to cold exposure was studied in the white rat. The preoptic area of 18 unanesthetized animals was cooled 9 h/day 5 days/wk, for a total of 80-150 h. One hour after a noradrenaline test injection (0.4 mg/kg), the experimental animals in which the preoptic area had been cooled to about 24 degrees C increased oxygen uptake by 81%, whereas those in which the preoptic area had been cooled to about 28 degrees C increased oxygen uptake by 48% (the control animals by only 37%). Despite their increased capacity for nonshivering thermogenesis, the experimental animals did not tolerate cold exposure (-10 degrees C) better than the controls. This development of nonshivering thermogenesis is thought to have been mediated by the hypothalamic temperature-sensitive neurons, and the possibility that it could explain the shift from shivering to nonshivering thermogenesis seen during adaptation to cold is discussed.
