Safe spaces? A social-ecological perspective on student perceptions of safety in the environment of the school canteen     

Paul Horton  Camilla Forsberg 《Educational research; a review for teachers and all concerned with progress in education》2020,62(1):95-110

ABSTRACT

Background Research suggests that negative peer interactions that compromise student safety and wellbeing often occur in spaces at school that are not easily visible, not adequately monitored, overcrowded and/or relatively unstructured. In a large online survey conducted in Swedish schools by the anti-bullying organisation, Friends, a small proportion of students indicated that they felt unsafe in the school canteen and responded to a question about why they felt unsafe there. As the canteen is often reported to be a space where negative peer interactions, such as harassment, bullying and other forms of school violence, occur, but little is known about why negative peer interactions occur there, we were particularly interested in exploring why some students perceived their school canteen to be an unsafe space.

Purpose Taking a social-ecological perspective, our aim was to investigate why students reported feeling unsafe in the environment of the school canteen.

Method In order to investigate this question, we analysed 1,547 responses from students in Swedish schools in grades 3–6 (ages 9–12). The responses were from the anti-bullying organisation Friends’ online questionnaires from 2011 to 2016. In the responses, students who indicated that they felt unsafe in the school canteen explained why they felt this way. Data were analysed qualitatively, using a six-step thematic approach.

Findings The analysis identified four key themes: Space constraints, Time restrictions, The risk of social blunders and The negative actions of others. We discuss the findings in terms of the macrosystem, exosystem, mesosystem and microsystem.

Conclusions In matters of student safety and wellbeing, we argue that it is not only important to consider the social context, but also how that context is interconnected with environmental and structural elements.  相似文献

Thermally multiplexed polymerase chain reaction

Amplification of multiple unique genetic targets using the polymerase chain reaction (PCR) is commonly required in molecular biology laboratories. Such reactions are typically performed either serially or by multiplex PCR. Serial reactions are time consuming, and multiplex PCR, while powerful and widely used, can be prone to amplification bias, PCR drift, and primer-primer interactions. We present a new thermocycling method, termed thermal multiplexing, in which a single heat source is uniformly distributed and selectively modulated for independent temperature control of an array of PCR reactions. Thermal multiplexing allows amplification of multiple targets simultaneously—each reaction segregated and performed at optimal conditions. We demonstrate the method using a microfluidic system consisting of an infrared laser thermocycler, a polymer microchip featuring 1 μl, oil-encapsulated reactions, and closed-loop pulse-width modulation control. Heat transfer modeling is used to characterize thermal performance limitations of the system. We validate the model and perform two reactions simultaneously with widely varying annealing temperatures (48 °C and 68 °C), demonstrating excellent amplification. In addition, to demonstrate microfluidic infrared PCR using clinical specimens, we successfully amplified and detected both influenza A and B from human nasopharyngeal swabs. Thermal multiplexing is scalable and applicable to challenges such as pathogen detection where patients presenting non-specific symptoms need to be efficiently screened across a viral or bacterial panel.  相似文献   

Three-dimensional kinematic analysis of the golf swing using instantaneous screw axis theory,Part 2: golf swing kinematic sequence     

Alessandro Vena  Dave Budney  Tom Forest  Jason P. Carey 《Sports Engineering》2011,13(3):125-133

A number of recent studies have measured the extent and timing of segment rotation during the golf swing. A promising technique, instantaneous screw axis (ISA) theory, could provide a better expression of segment rotation. In Part 1 of this two-part study, the objectives are to identify the ISA of the pelvis, shoulders and left arm during the downswing, compute segment angular velocity relative to that segment’s ISA and verify that ISA theory is a valid tool to analyse segment rotation during the golf swing. Results indicate that for all subjects, at least 71% of marker velocity is a result of rotation about their respective ISA, when averaging results over the duration of the downswing, confirming that motion is primarily rotational. Furthermore, ISA position and orientation of each segment approaches, on average, the expected gross axis of rotation, confirming that motion about the ISA is representative of joint motion.  相似文献
