Introduction. The quality of the habitat and increasing intensity of the educational load determine the negative changes of the health of schoolchildren, associated with a violation of immune mechanisms adaptation. Purpose. Study of features of the immune status of schoolchildren in the conditions of excessive hapten contamination by exogenous chemical factors. Materials and methods. Students who live in territories differing in the formation of excessive human-made chemical contamination (total 162 students) of senior and secondary education levels were examined. The analysis of contaminants in biological media utilizing gas chromatography method, high-performance liquid chromatography method, mass spectrometry method was performed. The state of cellular immunity was evaluated by the reaction of phagocytosis using formalinized ram erythrocytes and CD-immunogram parameters by flow cytometry. The state of humoral immunity identified with the production of serum immunoglobulins by radial immunodiffusion, as well as expression of specific antibodies to chemical factors by the method of allergosorbent testing. Results. We revealed an association of excess content of lead, nickel, formaldehyde, benzene, phenol in blood with deficiency phagocytic activity, imbalance of CD-subpopulations of immunocompetent cells characterized by the predominance of T lymphocytic activation (CD3+-lymphocytes), and a decrease in B-lymphocytes (CD19+-cells) both concerning the norm and to the group of schoolchildren with a permissible level of contaminating load. Secondary and senior students differed in imbalance of the immunoregulatory index CD4+/CD8+, and lower expression was revealed in high school students serum immunoglobulins IgM and IgA. In schoolchildren with excessive hapten contamination, there is a high level of sensitization to exogenous chemical factors according to the specific IgE antibodies to nickel, formaldehyde, and IgG to benzene, phenol, lead. Conclusion. The revealed imbalance of immune profile indices reflects the state of immunological health of schoolchildren, and the indices of cellular (immunoregulatory index CD4+/CD8+) and humoral (specific antihapten reagins) immunity, can be used as diagnostic for assessing the immune status in schoolchildren of secondary and senior levels of education in the conditions of excessive hapten contamination.

While national surveillance studies have stratified high school students’ health behavior outcomes, few ecological data sets have been explored, collected, and analyzed on the unique health problems of minority children. An area for which limited data on minority youth has been collected is Franklin County, home of the state capital of Kentucky. In the current study, we use baseline data collected in 2015 from students attending two high schools that were sites for Kentucky State University’s Youth Empowerment Project. We hypothesize that youth who reside in Franklin County would report lower maladjusted behaviors than their national and statewide counterparts in the same year of observation. Data analyses confirm that compared to their national- and state-level counterparts, Franklin County high school students were less likely to report riding with a driver who had been drinking alcohol, engaging in sexual intercourse, drinking alcohol before sexual intercourse, and experiencing non-condom use when engaged in sexual intercourse, forced sexual intercourse, dating violence, cyber bullying, suicidal ideation, and drug use. These findings suggest that Franklin County high school students may be exposed to environmental variables that may be preventive to maladjusted behaviors.

Since fall 2015, the University of Virginia’s (UVA) Engineering Student Council (ESC) has partnered with the nonprofit Virginia Science Olympiad (VASO) organization to host a Science Olympiad (SciOly) state tournament in Charlottesville, Virginia, each spring. This annual tournament brings over 2,000 middle and high school students, teachers, and parents to the UVA campus, and teams of 15–17 people from roughly 90 schools across Virginia participate in 46 different events (23 middle school, Division B; 23 high school, Division C) relating to the science, technology, engineering, and mathematics (STEM) fields throughout the day-long competition. The national SciOly organization sets the events and rules to comply with national education standards, and the VASO board coordinates the teams and tournaments within the state. By collaborating with VASO, UVA ESC was able to plan a large-scale SciOly tournament at UVA in approximately 10 mo with the support of the UVA School of Engineering and Applied Science. Since this event was planned and executed solely by undergraduates in cooperation with the nonprofit organization, there were institutional hurdles that were overcome through the months of planning. The Virginia SciOly state tournament has continued to be held at UVA with the support and cooperation of the UVA ESC and VASO, and bringing this tournament to UVA has allowed for increased excitement for participating K–12 students and a mitigated burden to the VASO organizers in planning the state competition. This paper aims to provide a resource for other universities to support STEM activities in K–12 outreach organizations, like SciOly, in the future.

Abstract The paper starts with signs that Cooper and I found in the Old City of Jerusalem. It describes how the term Linguistic Landscape was applied to the recollections of francophone high school students of the signs they had seen. It traces the many collections of photos employing digital cameras and cell-phones, and research that was derived from these collections, including published papers and books, a journal, and an annual workshop. The paper regrets the rarity of details of authorship (but reports who was responsible for the Jerusalem street signs), and the tendency to interpret signs without detailing authorship. Signs provide evidence of the state of literacy, but ignore the sociolinguistic make-up of the local community, missing that for earlier scholars “linguistic landscape” meant speech as well as writing. It regrets the paucity of efforts to provide a theory of public signage, arguing that this could be derived from the field of Semiotics.

This paper discusses issues of identity associated with Palestinian students’ integration in an Israeli-Arab high school. These students were born to Palestinian families that are considered as ‘traitors’ by Arabs living in the Palestinian Authority and in the State of Israel. Their parents have working relations with the State of Israel and are therefore living in a large city at the north of the country. The students experience some kind of identity conflict between them and the Israeli-Arab students learning in the same school. The students who came with their parents from the Palestinian Authority, have difficulties to define themselves and they constantly try avoiding the question: Where are you from? They usually say they are from Jerusalem and they hold a blue identity card. Moreover, these students deal with language difficulties. School today constitutes an educational framework for a variety of students, characterized by different abilities and needs. This sets a rather complicated challenge to the school management and staff that have to open the school doors and provide a response to the students. This paper is grounded in theories of high school education, self-identity, conflict between identities of minorities and adolescence. It reviews the identity issues associated with the Palestinian children’s national and self-identity, as well as the steps that school and the education system can take in order to promote their integration.

Information security in the context of digital literacy is a digital skill that enables safe and purposeful movement through virtual space. Due to rapid and unstoppable technological progress, multiplying opportunities and pushing the boundaries of digital technology and the Internet, the interest of the state and institutions within the state is to raise digital competencies of citizens, with special emphasis on children and youth as the most vulnerable groups of Internet users. The age limit and frequency of use of the Internet by young generations has been moved back a year due to the COVID-19 pandemic, and the concern for information security of young people is increasingly emphasized. If, and to what extent, knowledge of the issue of identification and authentication affects the information security of high school students aged 16 to 19 in the virtual space, the research question addressed by the authors of this paper was to determine which student behaviors pose a potential danger compromising their information security by establishing a correlation between the variables that determine student behavior and the variables used to examine their level of security in a virtual environment. The research was conducted using a questionnaire on a sample of high school students in the Republic of Croatia, the results of which showed that some students practice behaviors that are potentially dangerous, make them vulnerable and easy targets of cyber predators and attackers, which is why there is cause for concern and a need for a additional education of children of primary and secondary school age in the field of information security in the form of the introduction of the subject Digital Literacy. Based on the results, a model for assessing the level of digital literacy of adolescents that affect information literacy can be designed, but also further related research in the field of information literacy of children and youth can be conducted.

Academic Test

Differences in ratings of initial expectancy of success, perceived scholastic ability, and causal attributions were assessed for male and female high school students for a simulated academic test. Subjects were also differentiated on their achievement level (i.e., under- and overachievement) and the traditionality of their career aspirations. As predicted, higher expectancies were found for high performance achievers and nontraditional females. Males generally made more attributions to lack of effort for failure, as did low performance achievers. Females and high performance achievers attributed success more to effort. Hypotheses concerning differential usage of luck and ability attributions were not supported. Although there was an overall trend for females to be more external, traditionality also mediated causal attributions for females.
