The Network Orientations of Highly Resilient Urban Minority Youth: A Network-Analytic Account of Minority Socialization and Its Educational Implications

In this article the authors present a critical assessment of existing characterizations of resiliency and help-seeking behavior in light of their relevance to issues of minority youth socialization and schooling. In this effort, they reconceptualize the notion of resiliency within an analysis that highlights the more contextual aspects of how minority adolescent cope with structural forces that threaten healthy development. They show how key developmental transitions are thwarted by social forces that undermine the development of supportive relationships across multiple institutional sites (e.g., family, neighborhood, school). They also explain how resiliency is associated with egocentric networks that exhibit key structural characteristics. The authors conclude by discussing the implications of a critical network-analytic model of minority socialization in the development of future educational and youth mediations and reforms.     

Detection of replay attacks in cyber-physical systems using a frequency-based signature

This paper proposes a frequency-based approach for the detection of replay attacks affecting cyber-physical systems (CPS). In particular, the method employs a sinusoidal signal with a time-varying frequency (authentication signal) into the closed-loop system and checks whether the time profile of the frequency components in the output signal are compatible with the authentication signal or not. In order to carry out this target, the couplings between inputs and outputs are eliminated using a dynamic decoupling technique based on vector fitting. In this way, a signature introduced on a specific input channel will affect only the output that is selected to be associated with that input, which is a property that can be exploited to determine which channels are being affected. A bank of band-pass filters is used to generate signals whose energies can be compared to reconstruct an estimation of the time-varying frequency profile. By matching the known frequency profile with its estimation, the detector can provide the information about whether a replay attack is being carried out or not. The design of the signal generator and the detector are thoroughly discussed, and an example based on a quadruple-tank process is used to show the application and effectiveness of the proposed method.     

Analysis and design of quadratic parameter varying (QPV) control systems with polytopic attractive region

This paper proposes a gain-scheduling approach for systems with a quadratic structure. Both the stability analysis and the state-feedback controller design problems are considered for quadratic parameter varying (QPV) systems. The developed approach assesses/enforces the belonging of a polytopic region of the state space to the region of attraction of the origin, and relies on a linear matrix inequality (LMI) feasibility problem. The main characteristics of the proposed approach are illustrated by means of examples, which confirm the validity of the theoretical results.     

Disrupting the 'boys don't read' discourse: Primary school boys who love reading fiction

This article disrupts dominant discourses around boys and reading that often homogenise young males as reluctant, disengaged and, at times, adversarial readers. Rather than essentialising boys, we argue there is a need for a more sophisticated knowledge base about the influences, constraints and diverse experiences of boys as readers in society today. Drawing on interviews (n = 30) with Year 4 (8 to 9-year-old) boys at six schools, we consider their personal recounts of their enjoyment in reading, their preferred reading choices and narratives related to their experiences as readers at school. Analysis highlights boys' emerging reading interests, sophisticated and specific reading preferences, and changes in reading identities over time. Boys' preferences for particular fiction authors, novel series and genres dispute the common assumption in educational contexts that boys prefer to engage with non-fiction books. This finding is significant, as negative gendered stereotypes can impact on boys' reading self-concepts. It is also critical given Jerrim and Moss's recent research highlighting the importance of fiction in the development of reading skills. We consider implications for pedagogical practices that broaden reading experiences for the diversity of emerging masculine reading identities in nations such as Australia, where there is an absence of reading for pleasure in education policies.     

Accessible and engaging graphic design

Abstract

Graphic design is an important part of library marketing efforts that impact a wide range of projects, from the creation of outreach materials to the design of signage. Because it reaches so many areas of the library, it is important that graphic design work be done in a way to maximize accessibility and inclusion. By integrating accessibility considerations and best practices into design workflows, it is possible to create designs that are simultaneously accessible, inclusive, and visually engaging.     

Measuring Space and Furniture Occupancy in Academic Libraries: From Data Gathering to Visualization

Abstract

Academic libraries are a vital space for collaboration, socialization, research, and quiet study. To support these needs, they must offer a variety of environments, noise levels, and furniture to support varying student needs. However, it can be difficult to understand these specific needs and properly balance the types of spaces and seating alternatives to optimally meet them. This article describes a space usage study undertaken to determine patron needs and preferences and the resulting visualization of the data using Tableau Public. The project provided important insights into patron space preferences and use, and the methodology can be replicated at other institutions.     

Physiological intensity profile,exercise load and performance predictors of a 65-km mountain ultra-marathon

The aims of the study were to describe the physiological profile of a 65-km (4000-m cumulative elevation gain) running mountain ultra-marathon (MUM) and to identify predictors of MUM performance. Twenty-three amateur trail-runners performed anthropometric evaluations and an uphill graded exercise test (GXT) for VO_2max, ventilatory thresholds (VTs), power outputs (PMax, PVTs) and heart rate response (HRmax, HR@VTs). Heart rate (HR) was monitored during the race and intensity was expressed as: Zone I (VT2) for exercise load calculation (training impulse, TRIMP). Mean race intensity was 77.1%±4.4% of HRmax distributed as: 85.7%±19.4% Zone I, 13.9%±18.6% Zone II, 0.4%±0.9% Zone III. Exercise load was 766±110 TRIMP units. Race time (11.8±1.6h) was negatively correlated with VO_2max (r = ?0.66, P <0.001) and PMax (r = ?0.73, P <0.001), resulting these variables determinant in predicting MUM performance, whereas exercise thresholds did not improve performance prediction. Laboratory variables explained only 59% of race time variance, underlining the multi-factorial character of MUM performance. Our results support the idea that VT1 represents a boundary of tolerable intensity in this kind of events, where exercise load is extremely high. This information can be helpful in identifying optimal pacing strategies to complete such extremely demanding MUMs.
