Methods: The IBMEWG undertook sequential steps to inform the recommendations: (1) modified Delphi survey, (2) systematic review, (3) cross-sectional survey to physicians and nurse practitioners, (4) in-person meeting of IBMEWG to …

Rethinking The Classification Of Games And Sports In Physical Education: A Response To Changes In Sport And Participation, Justen O'Connor, Laura Alfrey, Dawn Penney

Research outputs 2022 to 2026

Background Through changing the way games are represented, classification systems have increased possibilities for teaching game forms beyond structured adult and singular official versions of popular sports. At the time of inception, the four-game form approach to classification (target, net/wall, striking/fielding, and invasion games) enabled modified, small sided conditioned games to be adapted to suit individual attributes, whilst reinforcing a core set of tactical and technical elements for transfer. With global shifts in patterns of sport participation, it is timely to review this dominant classification frame and the role it plays within physical education (PE). Purpose This paper proposes changes …

Research outputs 2022 to 2026

Background Malnutrition is considered a major public health challenge and is associated with a range of health issues, including childhood stunting. Stunting is a reliable and well-recognized indicator of chronic childhood malnutrition. The objective of this study is to determine the risk factors associated with stunting among 17,490 children below five years of age in Bangladesh. Methods Correlates of child stunting were examined using data generated by a cross-sectional cluster survey conducted in Bangladesh in 2019. The data includes a total of 17,490 children (aged < 5 years) from 64,400 households. Multiple logistic regressions were used to determine the risk factors associated with child stunting and severe stunting. Results The prevalence of stunting and severe stunting for children was 25.96% and 7.97%, respectively. Children aged 24 to < 36 months [Odds Ratio (OR) = 2.65, 95% CI: 2.30, 3.05] and aged 36 to < 48 months [OR = 2.33, 95% CI: 2.02, 2.69] had more risk of stunting compared to the children aged < 6 months. Children from Sylhet division had the greatest risk of stunting of all the eight divisions [OR = 1.26, 95% CI: 1.09, 1.46]. Children of secondary complete or higher educated mothers were less likely to develop stunting [OR = 0.66, 95% CI: 0.56, 0.79] compared with children of mothers having no education at all. Similarly, children of secondary complete or higher educated father [OR = 0.74, 95% CI: 0.63, 0.87] were found to have lower risk of stunting compared with children whose father hadn’t any education. Substantially lower risk of stunting was observed among children whose mother and father both completed secondary education or above [OR = 0.59, 95% CI: 0.52, 0.69]. Children from the richest households [OR = 0.49, 95% CI: 0.41, 0.58] had 51% lower odds of stunting compared to children from the poorest households. Conclusions After controlling for socioeconomic and demographic factors, parental education and household position in the wealth index were found to be the most important determinants of child stunting in Bangladesh.

Strength Training In Swimming, Klaus Wirth, Michael Keiner, Stefan Fuhrmann, Alfred Nimmerichter, Gregory G. Haff

Research outputs 2022 to 2026

This narrative review deals with the topic of strength training in swimming, which has been a controversial issue for decades. It is not only about the importance for the performance at start, turn and swim speed, but also about the question of how to design a strength training program. Different approaches are discussed in the literature, with two aspects in the foreground. On the one hand is the discussion about the optimal intensity in strength training and, on the other hand, is the question of how specific strength training should be designed. In addition to a summary of the current …

The Internet of Drones (IoD) has attracted increasing attention in recent years because of its portability and automation, and is being deployed in a wide range of fields (e.g., military, rescue and entertainment). Nevertheless, as a result of the inherently open nature of radio transmission paths in the IoD, data collected, generated or handled by drones is plagued by many security concerns. Since security and privacy are among the foremost challenges for the IoD, in this paper we conduct a comprehensive review on security issues and solutions for IoD security, discussing IoD-related security requirements and identifying the latest advancement in …

A Low-Cost Machine Learning Based Network Intrusion Detection System With Data Privacy Preservation, Jyoti Fakirah, Lauhim Mahfuz Zishan, Roshni Mooruth, Michael L. Johnstone, Wencheng Yang

Research outputs 2022 to 2026

Network intrusion is a well-studied area of cyber security. Current machine learning-based network intrusion detection systems (NIDSs) monitor network data and the patterns within those data but at the cost of presenting significant issues in terms of privacy violations which may threaten end-user privacy. Therefore, to mitigate risk and preserve a balance between security and privacy, it is imperative to protect user privacy with respect to intrusion data. Moreover, cost is a driver of a machine learning-based NIDS because such systems are increasingly being deployed on resource-limited edge devices. To solve these issues, in this paper we propose a NIDS …

Research outputs 2022 to 2026

Leptospirosis, typhoid and dengue are three water-related diseases influenced by environmental factors. We examined whether seasonality and rainfall predict reported syndromes associated with leptospirosis, typhoid and dengue in Fiji. Poisson generalised linear models were fitted with s6 early warning, alert and response system (EWARS) syndromic conditions from March 2016 until December 2020, incorporating seasonality, temperature and rainfall. Watery diarrhoea, prolonged fever and suspected dengue displayed seasonal trends with peaks corresponding with the rainy season, while bloody diarrhoea, acute fever with rash and acute jaundice syndrome did not. Seasonality was the most common predictor for watery and bloody diarrhoea, prolonged fever, …

Testing The Limits Of International Society? Trust, Aukus And Indo-Pacific Security, Jamal Barnes, Samuel M. Makinda

Research outputs 2022 to 2026

When Australia reneged on a AUD$90 billion submarine contract with France in 2021 as it joined AUKUS, a new trilateral military partnership between Australia, the UK and the US, it was accused of lying and breaching France's trust. This perceived act of betrayal not only led to a deterioration in the diplomatic relationship between Australia and France, but it also drew attention to the consequences of violating the norm of pacta sunt servanda—agreements must be kept. Although it is recognized that breaches of trust undermine relationships, what has been underexplored is how a violation of norms can also undermine the …

Contexts For Children’S Digital Citizenship In India, Korea And Australia: A Literature Review, Kylie Stevenson, Emma Jayakumar, Viet Tho Le, Yeonghwi Ryu, Harrison See

Research outputs 2022 to 2026

Children’s digital citizenship today: In an increasingly digitised and technically mediated world, an individual’s digital citizenship, or “ability to use digital technology and media in safe, responsible and ethical ways” (DQ Institute, 2019) has never been more relevant, particularly when it concerns our youngest digital citizens. Navigating online spaces safely and confidently are skills fundamental to a modern individual’s social and emotional development, education, work and play. A digital citizen’s abilities, however, are greatly impacted by notions of access; not just physical access, but also access mediated culturally and socio-economically. Less is known about very young children’s experiences of digital …

Sport-Specific Crossover Point Differences During A Maximal Oxygen Consumption Test, Joseph R. Stanzione, George A. Brooks, Michael L. Bruneau, Duncan N. French, Jennifer A. Nasser, Sinclair A. Smith, Stella L. Volpe

Research outputs 2022 to 2026

Introduction/Purpose: The crossover point occurs during exercise when one transitions energy substrates from fat to carbohydrate predominance. The crossover point varies in an intensity-dependent manner; however, less is known about its specificity in sports with varying metabolic demands. The purpose of our study was to determine if various sports yield differences in the time to crossover and heart rate and percentage of maximal oxygen consumption (V O2max) at crossover during a standardized exercise protocol.

Methods: A total of 77 athletes (39 women, 38 men; 39.1 + 10.4 yr of age) were measured for respiratory exchange ratio during a modified Taylor …

A Framework Of Lightweight Deep Cross-Connected Convolution Kernel Mapping Support Vector Machines, Qi Wang, Zhaoying Liu, Ting Zhang, Shanshan Tu, Yujian Li, Muhammad Waqas

Research outputs 2022 to 2026

Deep kernel mapping support vector machines have achieved good results in numerous tasks by mapping features from a low-dimensional space to a high-dimensional space and then using support vector machines for classification. However, the depth kernel mapping support vector machine does not take into account the connection of different dimensional spaces and increases the model parameters. To further improve the recognition capability of deep kernel mapping support vector machines while reducing the number of model parameters, this paper proposes a framework of Lightweight Deep Convolutional Cross-Connected Kernel Mapping Support Vector Machines (LC-CKMSVM). The framework consists of a feature extraction module …

Reciprocal Regulation Of Mitofusin 2-Mediated Mitophagy And Mitochondrial Fusion By Different Pink1 Phosphorylation Events, Jiajia Li, Xiawei Dang, Antonietta Franco, Gerald W Dorn

2020-Current year OA Pubs

Mitochondrial repair is essential to metabolic homeostasis. Outer mitochondrial membrane mitofusin (MFN) proteins orchestrate mitochondrial fusion that opposes mitochondrial degeneration caused by senescence. Depending upon physiological context, MFN2 can either mediate mitochondrial fusion or recruit cytosolic Parkin to initiate mitophagic elimination. Because it is not clear how these events are counter-regulated we engineered and expressed MFN2 mutants that mimic phosphorylated or non-phosphorylatable MFN2 at its PINK1 phosphorylation sites: T111, S378, and S442. By interrogating mitochondrial fusion, polarization status, and Parkin binding/mitophagy as a function of inferred MFN2 phosphorylation, we discovered that individual MFN2 phosphorylation events act as a biological "bar-code", …

What Does Homophily Do? A Review Of The Consequences Of Homophily, Gokhan Ertug, Julia Brennecke, Balaza Kovacs, Tengjian Zou

Research Collection Lee Kong Chian School Of Business

Understanding the consequences of homophily, which is among the most widely observed social phenomena, is important, with implications for management theory and practice. Therefore, we review management research on the consequences of homophily. As the consequences of homophily have been studied at the individual, dyad, team, organizational, and macro levels, we structure our review accordingly. We highlight findings that are consistent and contradictory, as well as those that point to boundary conditions or moderators. In conducting our review, we also derive implications for management research from insights gained by research in other disciplines on this topic. We raise specific issues …

Concept Links And Return Momentum, Qianqian Du, Dawei Liang, Zilin Chen, Jun Tu

Research Collection Lee Kong Chian School Of Business

Unlike traditional asset categories (e.g., industry classifications) that are generally defined clearly, some groups of stocks are tied to certain loosely defined “concepts” (e.g., e-commerce). When investors find it difficult to analyze ambiguous concept-oriented information, information diffuses slowly, creating “concept momentum”. Based on unique concept data in the Chinese stock market, this study constructs a concept-momentum strategy that involves buying stocks from past winning concepts and selling stocks from past losing concepts, which can generate pronounced abnormal returns. Neither risk factors, firm-level momentum, nor industry-level momentum can explain concept momentum. Furthermore, we find that both the underreaction and cross-stock lead-lag …

Historical Disproportional Placement Of Students In Special Education Based On Race And Ethnicity, Margaret A. Dalton

Faculty Scholarship

This commentary, presented at the Practicing Law Institute in San Francisco on September 12, 2022, takes a look back at the 1970s, when the 9th Circuit Court of Appeals attempted to remedy the disproportionate placement of black students into isolated special education classrooms. As a result of legal challenges, the 9th Circuit granted an injunction to halt the practice of placing students in classrooms for the "educable mentally retarded" based solely on IQ tests. The challenge since that time has been how to identify and use culturally sensitive testing to determine ability levels, when some states, including California, forbid the …

Critical Analysis Of Arl Member Institutions’ Diversity Statements, V. Dozier, Adebola Fabiku, Sandra A. Enimil

Copley Library: Faculty Scholarship

In March 2018, the Board of Directors of the Association of Research Libraries (ARL) approved a new mission statement that includes a call to “promote equity and diversity” and lists “diversity, equity, and inclusion” (DEI) as one of its four priorities. ARL encourages but does not mandate similar visible commitments from its member institutions. This is evident by the resource webpage that ARL maintains entitled, “ARL Library Statements and Signs Affirming Our Core Beliefs.” The listed members represent approximately 19% of ARL’s membership. After reading the existing statements, the authors noticed a similar pattern in terms and context. This led …

Coral Reef Benthic Community Changes In The Anthropocene: Biogeographic Heterogeneity, Overlooked Configurations, And Methodology, Miriam Reverter, Stephanie B. Helber, Sven Rohde, Jm Goeij, Peter J. Schupp

School of Biological and Marine Sciences

Non-random community changes are becoming more frequent in many ecosystems. In coral reefs, changes towards communities dominated by other than hard corals are increasing in frequency, with severe impacts on ecosystem functioning and provision of ecosystem services. Although new research suggests that a variety of alternative communities (i.e. not dominated by hard corals) exist, knowledge on the global diversity and functioning of alternative coral reef benthic communities, especially those not dominated by algae, remains scattered. In this systematic review and meta-analysis of 523 articles, we analyse the different coral reef benthic community changes reported to date and discuss the advantages …

Academic Library Succession Planning In The University Of California (Uc) System, Crystal Goldman

Dissertations

The Library and Information Science (LIS) literature has made clear that academic libraries in the U.S. have experienced decades of hiring freezes and budget cuts that reduced staffing overall and eliminated many middle management positions. Consequently, now that baby boomer library managers and administrators are beginning to retire, there are few qualified applicants to replace them. Thus, many in the LIS field have called for better succession planning by top-level library administrators (e.g., Deans, Directors, University Librarians). Few studies, however, have directly addressed this issue by examining these administrators’ perceptions or behavior regarding succession planning. This study begins to fill …

Community Representation Among Nonprofit Leadership: Why Should The Board Reflect Those Whom It Serves?, William N. Derwin

Master's Projects and Capstones

Nonprofits, as vehicles for the delivery of essential community services, are integral to the health and prosperity of their communities. But many nonprofit leaders do not represent or adequately understand the community members whom their organizations serve. This study, through a literature review and a qualitative analysis of several expert interviews, evaluates the significance of community representation among nonprofit leadership, the best practices for improving community representation, and the relationship between a nonprofit’s community ties and the outcomes of its grant applications. As the results of the study indicate, it is essential for nonprofit leaders to understand their communities; any …

Judging Without A J.D., Sara Sternberg Greene, Kristen M. Renberg

Faculty Scholarship

One of the most basic assumptions of our legal system is that when two parties face off in court, the case will be adjudicated before a judge who is trained in the law. This Essay begins by showing that, empirically, the assumption that most judges have legal training does not hold true for many low-level state courts. Using data we compiled from all fifty states and the District of Columbia, we find that thirty-two states allow at least some low-level state court judges to adjudicate without a law degree, and seventeen states do not require judges who adjudicate eviction cases …

The Diversity Risk Paradox, Veronica Root Martinez

Faculty Scholarship

There is a growing body of literature discussing the proper role of diversity, equity, and inclusion efforts by and within public firms. A combination of forces brought renewed energy to this topic over the past few years. The #MeToo movement demonstrated a whole host of inequities faced by women within workplaces. Business Roundtable’s 2019 Statement on the Purpose of a Corporation rejected the view that the purpose of the corporation was solely to be focused on the maximization of shareholder wealth. And, in 2020, the murder of George Floyd ignited a racial reckoning within the United States, which prompted many …
