IceAct is a proposed surface array of compact (50 cm diameter) and cost-effective Imaging Air Cherenkov Telescopes installed at the site of the IceCube Neutrino Observatory at the geographic South ...Pole. Since January 2019, two IceAct telescope demonstrators, featuring 61 silicon pho- tomultiplier (SiPM) pixels have been taking data in the center of the IceTop surface array during the austral winter. We present the first analysis of hybrid cosmic ray events detected by the IceAct imaging air-Cherenkov telescopes in coincidence with the IceCube Neutrino Observatory, includ- ing the IceTop surface array and the IceCube in-ice array. By featuring an energy threshold of about 10 TeV and a wide field-of-view, the IceAct telescopes show promising capabilities of im- proving current cosmic ray composition studies: measuring the Cherenkov light emissions in the atmosphere adds new information about the shower development not accessible with the current detectors, enabling significantly better primary particle type discrimination on a statistical basis. The hybrid measurement also allows for detailed feasibility studies of detector cross-calibration and of cosmic ray veto capabilities for neutrino analyses. We present the performance of the telescopes, the results from the analysis of two years of data, and an outlook of a hybrid simulation for a future telescope array.
The goal of this paper was to examine the relation between teachers and students and between students on societal involvement in Dutch secondary schools. As such, we studied the role of parents on ...adolescents' societal involvement and to what extent positive teacher-student and student-student relationships reduced differences in societal involvement due to parental background differences. To estimate this cross-sectional multilevel analyses, a rich combination of datasets from the Netherlands was used, encompassing 4,128 15-year-old students in 58 schools in 2010/2011. The results showed that teacher-student relations and student-student relations were positively associated with societal involvement. The level of societal involvement differed between students' from households with lower incomes, level of education and employment, even though parenting styles seemed unrelated to societal involvement. Students from higher educated parents were found to benefit more from these positive relationships with teachers. This advantage arguably amplifies the differences in societal involvement between students with lower and higher educated parents. Future studies can give further insight into the role of classroom interrelations using additional longitudinal data or focus on more qualitative observations to explore the role of classroom interrelations and their influence on developing societal involvement.
This study examined the association between teacher-student and student-student relationships on societal involvement in Dutch primary and secondary schools. In addition, it studied differences in ...the effects of teacher-student relationships and student-student relationships among students from various parental backgrounds on societal involvement, indicating the possibilities of schools to reduce social inequalities between students.

data were used for students age 12 and age 15 to investigate the relative and lasting association between teacher-student and student-student relationships from primary to secondary school on societal involvement. In analysis A, 9,334 students from 1,036 classes were included in the analyses. In analysis B, 934 students from 667 classes were included. The results showed that teacher-student relationships are positively associated with societal involvement in both primary and secondary school. The association between teacher-student relationships and societal involvement in primary school were also important in secondary school. Moreover, positive teacher-student relationships were more beneficial for societal involvement for students with parents from lower educated backgrounds, indicating that schools can compensate for inequalities between students. Student-student relationships were found to be unrelated to societal involvement in both primary and secondary school.
This article examines the role of teachers, parents, and friends in stimulating the development of societal interest among adolescents. It assesses the extent teachers can compensate for societal ...interest differences among adolescents that arise due to socioeconomic differences. The YeS panel study is used, with 587 students aged 13-18 assessed annually over a six-year period (2010-2015) and uses latent growth curve modeling (LGCM). Our findings indicate that awareness-raising by each of the three groups contributes to the development of societal interest among adolescents, with teachers being the most influential socializing agent. Teachers were more influential societal interest development among adolescents from less privileged homes, confirming our hypothesis that schools can compensate for societal interest differences.
