School and community factors involved in Chilean students’ perception of school safety

Identifying and understanding predictors of school safety perceptions is important due to its consequences for students. However, it is not clear what school‐related factors most contribute to explaining students’ perception of school safety, and how they relate to community‐related factors such as neighborhood safety. The purpose of this study was to understand the factors associated with Chilean elementary and middle school students’ perceptions of school safety. We used a sample of 5,455 students from low socioeconomic status public schools, and analyzed the predictive value of peer physical and verbal victimization; teacher and school staff victimization; teacher's social support; and perception of safety in the students’ neighborhoods on perceptions of school safety. Findings showed that although different forms of school violence, particularly peer physical victimization and physical and sexual victimization from teachers and school staff, contribute to students’ perception of school safety, the highest contribution came from students perceiving their neighborhoods as unsafe. In contrast, teacher social support contributed to increased levels of perceived school safety. We discuss the need for school‐based interventions that address physical victimization and engage teachers in prosocial and less punitive approaches to foster a positive and safe school climate, and in fostering school–community partnerships.     

Dual governance structures in action sports: institutionalization processes of professional snowboarding revisited

Abstract

This article examines the current governance structures in international competitive snowboarding and analyses empirically how key actors operate within the diverging logics that shape such structures. We expand upon the existing literature on professional snowboarding by offering a more contemporary understanding of the constantly evolving processes of institutionalization. Qualitative data was gathered from the authors’ first-hand experiences with international snowboarding, based on (1) interviews with system insiders, (2) document analysis, and (3) participant observations. Two dominant and contradicting logics of competitive snowboarding were identified, forming a fragmented, dual institutional structure that we call the industry-based and nation-based governance model. Our findings suggest that recent professionalization processes have led to defragmentation efforts, thus signalling a shift towards a nation-based governance focus. Therefore, we conclude that other action sports that will join the Olympics, such as surfing and skateboarding, are advised to find solutions for mediating inherent contradictions of governance logics to avoid institutional fragmentation at an early stage.     

Decentralized continuous MRAC with local asymptotic sliding modes of nonlinear delayed interconnected systems

In this contribution, we develop continuous completely decentralized state-feedback adaptive controllers with sliding mode for a class of large-scale interconnected systems with nonlinear interconnections with unknown time-varying state delays. The novel contribution of this paper is that asymptotically exact tracking within the framework of completely decentralized direct continuous adaptive control is possible also for a class of nonlinear plants with matched interconnections and disturbances.     

Dynamics of mental model construction from text and graphics

When students read for learning, they frequently are required to integrate text and graphics information into coherent knowledge structures. The following study aimed at analyzing how students deal with texts and how they deal with graphics when they try to integrate the two sources of information. Furthermore, the study investigated differences between students from different school types and grades. Forty students from grades 5 and 8 from higher track and lower track of the German school system were asked to process and integrate texts and graphics in order to answer items from different levels of a text–picture integration taxonomy. Students’ eye movements were recorded and analyzed. Results suggest fundamentally different functions of text and graphics, which are associated with different processing strategies. Texts are more likely to be used according to a coherence-formation strategy, whereas graphics are more likely to be used on demand as visual cognitive tools according to an information-selection strategy. Students from different tracks of schooling revealed different adaptivity with regard to the requirements of combining text and graphic information.     

What Goes Down Must Come Up: Communication as Incarnation and Transcension

In this essay, I conceptualize incarnation from a communicative point of view by juxtaposing it with the concept of transcension. Subsequently, I reflect on the potential value of studying these concepts for communication research.
