Published: July 2024

PurposeWith the development of intelligent technology, deep learning has made significant progress and has been widely used in various fields. Deep learning is data-driven, and its training process requires a large amount of data to improve model performance. However, labeled data is expensive and not readily available.Design/methodology/approachTo address the above problem, researchers have integrated semi-supervised and deep learning, using a limited number of labeled data and many unlabeled data to train models. In this paper, Generative Adversarial Networks (GANs) are analyzed as an entry point. Firstly, we discuss the current research on GANs in image super-resolution applications, including supervised, unsupervised, and semi-supervised learning approaches. Secondly, based on semi-supervised learning, different optimization methods are introduced as an example of image classification. Eventually, experimental comparisons and analyses of existing semi-supervised optimization methods based on GANs will be performed.FindingsFollowing the analysis of the selected studies, we summarize the problems that existed during the research process and propose future research directions.Originality/valueThis paper reviews and analyzes research on generative adversarial networks for image super-resolution and classification from various learning approaches. The comparative analysis of experimental results on current semi-supervised GAN optimizations is performed to provide a reference for further research.
Children’s sensemaking of algorithms and data flows across YouTube and social media
Authors: Starks Allison , Reich Stephanie Michelle 
Published: July 2024

Purpose
This study aims to explore children’s cognitions about data flows online and their understandings of algorithms, often referred to as algorithmic literacy or algorithmic folk theories, in their everyday uses of social media and YouTube. The authors focused on children ages 8 to 11, as these are the ages when most youth acquire their own device and use social media and YouTube, despite platform age requirements.

Design/methodology/approach
Nine focus groups with 34 socioeconomically, racially and ethnically diverse children (8–11 years) were conducted in California. Groups discussed data flows online, digital privacy, algorithms and personalization across platforms.

Findings
Children had several misconceptions about privacy risks, privacy policies, what kinds of data are collected about them online and how algorithms work. Older children had more complex and partially accurate theories about how algorithms determine the content they see online, compared to younger children. All children were using YouTube and/or social media despite age gates and children used few strategies to manage the flow of their personal information online.

Practical implications
The paper includes implications for digital and algorithmic literacy efforts, improving the design of privacy consent practices and user controls, and regulation for protecting children’s privacy online.

Originality/value
Research has yet to explore what socioeconomically, racially and ethnically diverse children understand about datafication and algorithms online, especially in middle childhood.

Published: July 2024

PurposeThe current study seeks to explore the links between principal self-efficacy, openness to change, well-being, and transformational leadership. Specifically, we tested a mediated-effects model where principal self-efficacy and openness to change were treated as independent variables, well-being as mediator, and transformational leadership as dependent variable.Design/methodology/approachSurvey data were collected from 351 principals employed in Turkish schools and analysed using confirmatory factor analysis and structural equation modelling.FindingsThe results suggested the direct empirical relationship of principal self-efficacy and openness to change with transformational leadership, and indirect through professional well-being.Originality/valueOur study enriched our understanding of school leadership by elucidating the potential mechanisms that underpin the implementation of transformational leadership practices.
Leadership for action on climate change: the role of education policy and professional standards in the Hong Kong context
Authors: Campbell Paul 
Published: July 2024

PurposeUsing Hong Kong as the context of study, this paper examines the role of education policy, particularly professional standards for teachers (PST) and principals (PSP), in enabling leadership for action on contemporary challenges and crises such as climate change.Design/methodology/approachThis paper utilises critical policy analysis (CPA) and an associated analytical framework to examine key policy texts that are designed with the intent to frame the professional roles, practice and learning of educators and leaders in Hong Kong. The data analysis process involved rounds of descriptive coding, which was then collated into broader themes for discussion.FindingsPolicy texts emphasised the scope for educators to exercise leadership and decision-making that supports innovation, improvement and collaboration in the pursuit of a broad social mission for education, emphasising the skills students do and will need to respond to dynamic contemporary challenges. However, how this relates to broader policy goals, and limited articulation of the means through which this is possible, questions remain about the extent to which teachers and leaders are able to exercise leadership for action on climate change.Originality/valueThis study has important implications for how those in policymaking, research and practice spaces understand the framing of the role of teachers and school leaders in policy and the influence of this on their capacity to lead action on contemporary challenges and crises, such as climate change.
Stakeholder engagement and nonprofit organizations' (NPOs) accountability: a social media-based study of the Australian 2019/2020 bushfire crisis
Authors: Nguyen Mai , Alshamari Alia , Wills Debbie 
Published: July 2024

Purpose
This study aims to examine the impact of stakeholder engagement on accountability, within nonprofit organizations (NPOs). Given the pivotal role NPOs play in disaster management and community welfare, it is crucial to gain an understanding of the obligations of NPOs, in terms of their disaster responses and accountability.

Design/methodology/approach
Using a case-study approach, the investigation features a content analysis of social media comments regarding the Australian Red Cross’ (ARC) funds’ allocation during the 2019/2020 bushfires, followed by a similar analysis of ARC's reports. Inspired by Carnegie et al.'s (2021) definition of accounting as a social science, this study uses dialogic theory and a transformative participatory framework, to evaluate how interactive stakeholder engagement influenced accountability strategies used by the NPO, to ensure its sustainable development.

Findings
The findings reveal that there was a significant increase in stakeholder engagement on social media, following negative media coverage, with participants voicing concerns over ARC’s method of funds’ allocation, delays in funds distribution and seemingly excessive administrative costs. ARC addressed these concerns by issuing Bushfire Reports, and conducting online Q&A sessions, in a bid to establish transparency. This study emphasizes how dialogic accounting can challenge accounting's limited scope – one that often overlooks ecological concerns and social justice.

Originality/value
This study uses the perspective of dialogic accounting theory to explore the relationship between stakeholder engagement on social media, and NPO accountability. It demonstrates how robust stakeholder engagement can challenge NPOs to establish accountability, thereby bridging the information gap between themselves and the public. The use of dialogic accounting theory allows the study to shift from the traditional focus of accounting research, which is the financial objectives of powerful entities, to the voices of the marginalized, the stakeholders, who are impacted by NPO decisions, and, in doing so, it highlights the potential for NPOs to foster accountability, and so advance sustainable development initiatives.
How are news portals integrated into daily news habits? A study on news trust, news repertoires and political participation in South Korea
Authors: Lor Zhieh , Choi Jihyang , Oh Hae Jung 
Published: July 2024

PurposeThe modern high-choice news environment has changed the way people consume news. We examined the structure of news repertories, the role of news trust (and cynicism) in shaping news repertoires, and the effects of different news repertoires on political participation in the South Korean news environment, where news portals function as major news sources.Design/methodology/approachWe conducted a two-wave national survey of adults in January and February 2022 with a three-week time interval. Latent profile analyses and latent profile regression were employed.FindingsFour major news repertoires were identified: news portal-concentrated, portal and TV combination, all except print and SNS, and platform omnivores. Trust in mainstream news media was found to be high in the following order: platform omnivores, all except print and SNS, portal and TV combination, and portal-concentrated repertoires. Cynicism about mainstream media was found to be higher among the users of portal-concentrated repertoire than those using the other three repertoires. Those who rely mainly on news portals for news (i.e. portal-concentrated) were less likely to participate in politics.Originality/valueThis study provides comprehensive insights into how audience perceptions of trust and cynicism toward mainstream news media shape news consumption patterns in today’s high-choice media environment. In particular, the findings of this study illuminate the function of news portals as a substitute platform for those who exhibit lower trust and higher cynicism toward mainstream news media.
Do independent directors enhance better corporate governance in companies in India?
Authors: Arora Akshita 
Published: July 2024

PurposeThe effectiveness of independent directors in making autonomous decisions for better corporate governance in organizations has often been questioned. This paper aims to investigate their role in company’s decision making in India and the reasons behind their ineffectiveness.Design/methodology/approachThis paper examines the regulatory environment and ongoing reforms in which independent directors operate. It identifies crucial factors such as ownership patterns, the appointment and selection process that affect their autonomy. The analysis draws from newspaper articles, blogs, India’s regulatory requirements, The Companies Act and relevant related literature.FindingsThe findings reveal that the independence of directors remains largely in form but not in function. This paper recommends a fair and more robust selection through an independent authority, and disclosure of the resignations of independent directors. Independent directors should be given more powers and their risk-reward scheme should be analyzed.Originality/valueThe paper emphasizes the need for independent directors to be truly independent from the senior management, promoters, and other existing directors. It calls for tighter and more transparent appointment procedures to ensure that independent directors are not influenced by senior management and can bring objectivity to the company board.
Crime dynamics in Edmonton’s train stations: analysing hot spots, harm spots and offender patterns
Authors: Ottaro Paul , Ariel Barak , Harinam Vincent 
Published: July 2024

PurposeThe objectives of this study are to (a) identify spatial and temporal crime concentrations, (b) supplement the traditional place-based analysis that defines hot spots based on counted incidents with an analysis of crime severity and (c) add to the research of hot spots with an analysis of offender data.Design/methodology/approachThis study explores crime concentration in mass transit settings, focusing on Edmonton’s Light Rail Transit (LRT) stations in 2017–2022. Pareto curves are used to observe the degree of concentration of crime in certain locations using multiple estimates; trajectory analysis is then used to observe crime patterns in the data on both places and offenders.FindingsA total of 16.3% of stations accounted for 50% of recorded incidents. Train stations with high or low crime counts and severity remained as such consistently over time. Additionally, 3.6% of offenders accounted for 50% of incident count, while 5% accounted for 50% of harm. We did not observe differences in the patterns and distributions of crime concentrations when comparing crime counts and harm.Research limitations/implicationsHot spots and harm spots are synonymous in low-crime-harm environments: high-harm incidents are outliers, and their weight in the average crime severity score is limited. More sensitive severity measures are needed for high-frequenty, low-harm enviornments. Practical implicationsThe findings underscore the benefits of integrating offender data in place-based applied research.Originality/valueThe findings provide additional evidence on the utility of place-based criminology and potentially cost-effective interventions.
Promoting home safety with older adults: a systematic review of occupational therapy interventions
Authors: Carrick Ryan M. , Brinkley Taylor , Harvey Cheyenne , Johnson Ashtin , Penney Taylor , Sauls Tanner Kate , Kearney Pamalyn J. 
Published: July 2024

Purpose
Due to the projected increase in the older adult population, occupational therapy providers will have an increasing role in supporting health outcomes for older adults in the coming years. The purpose of this systematic review was to determine the effectiveness of occupational interventions to promote home safety in older adults.

Design/methodology/approach
This systematic review followed the Preferred Reporting Items of Systematic reviews (PRISMA) guidelines. Articles were double screened by separate researchers, then exported and managed in EndNote. The Risk of Bias Table determined certainty of evidence for themes.

Findings
Three main preliminary themes were identified from the 17 included articles. Themes include multimodal interventions (n= 6), exercise interventions (n= 9) and home modifications (n = 2). None of the articles explicitly defined home safety, but distal outcomes related to safety included: increased strength, balance improvement and functional mobility.

Research limitations/implications
Importantly, an absent consensus for a definition of home safety limits the results of this systematic review while at the same time providing opportunity for future research.

Practical implications
Exercise combined with nutrition provided the strongest intervention evidence for physical functionality. Additionally, home modifications alone may be insufficient to result in improved home safety.

Social implications
An occupational therapy’s (OT) holistic approach benefits older adults through evidenced-based interventions improving home safety, independence in functional tasks and overall quality of life.

Originality/value
Findings provide clinicians with information on the effectiveness of interventions within the scope of OT that can be implemented within the home to promote home safety.
“We can work on this”: exploring supervisor approaches to feedback in the context of writing for a professional doctorate
Authors: Tuck Jackie 
Published: July 2024

Purpose
This paper aims to show how an Academic Literacies lens can contribute to a deeper understanding of writing for a professional doctorate (PD) by focusing both on the language of supervisors’ written feedback and on student and supervisor perspectives on feedback throughout Year 1 (Y1).

Design/methodology/approach
Firstly, written feedback summaries on formative assessments across two Y1 cohorts on a UK PD programme were analysed thematically to identify patterns in feedback practices. Secondly, two longitudinal, detailed student/supervisor case studies were developed, drawing on multiple data sources.

Findings
Supervisors’ written feedback enacted an encouraging dialogue around assessed writing, discursively constructing a sense of solidarity on the doctoral journey, focusing on the “long view”. Case study analysis, however, revealed tensions centred around jarring discontinuities in students’ feedback experience as they transitioned from formative to summative assessment at the end of Y1.

Research limitations/implications
The paper demonstrates that an Academic Literacies approach can offer valuable insights into the specific, situated context of writing for a distance learning PD and makes the case for greater attention to writing in contexts of partly taught doctorates.

Practical implications
Findings suggest that PD programmes should work towards providing continuity of feedback experience, through supervisor and examiner training and through assessment arrangements which support students to navigate challenging transitions between formative and summative phases of assessment.

Originality/value
This paper reports on an innovative research design which combined a textual “snapshot” of supervisory feedback, paying close attention to language, with detailed longitudinal case studies exploring perspectives on feedback over time. It contributes to doctoral writing research by throwing light on the relatively underexplored domain of writing in the taught phase of the PD. It contributes to doctoral education studies by highlighting the central role of feedback on writing in shaping the experience of PD researchers.
Investigation of the mechanical properties of lead-free Sn-58Bi solder alloy with cobalt addition through flux doping
Authors: Kamaruzzaman Lina Syazwana , Goh Yingxin , Goh Yi Chung 
Published: July 2024

Purpose
This study aims to investigate the effect of incorporating cobalt (Co) into Sn-58Bi alloy on its phase composition, tensile properties, hardness and thermal aging performances. The fracture morphologies of tensile-tested solders are also investigated to correlate the microstructural changes with tensile properties of the solder alloys. Then, the thermal aging performances of the solder alloys are investigated in terms of their intermetallic compound (IMC) layer morphology and thickness.

Design/methodology/approach
The Sn-58Bi and Sn-58Bi-xCo, where x = 1.0, 1.5 and 2.0 Wt.%, were prepared using the flux doping technique. X-ray diffraction (XRD) is used to study the phase composition of the solder alloys, whereas scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX) are used to investigate the microstructure, fractography and compositions of the solders. Tensile properties such as ultimate tensile strength (UTS), Young’s modulus and elongation are tested using the tensile test, whereas the microhardness value is gained from the micro-Vickers hardness test. The morphology and thickness of the IMC layer at the solder’s joints are investigated by varying the thermally aging duration up to 56 days at 80°C.

Findings
XRD analysis shows the presence of Co3Sn2 phase and confirms that Co was successfully incorporated via the flux doping technique. The microstructure of all Sn-58Bi-xCo solders did not differ significantly from Sn-58Bi solders. Sn-58Bi-2.0Co solder exhibited optimum properties among all compositions, with the highest UTS (87.89 ± 2.55 MPa) at 0.01 s−1 strain rate and the lowest IMC layer thickness at the interface after being thermally aged for 56 days (3.84 ± 0.67 µm).

Originality/value
The originality and value of this research lie in its novel exploration of the flux doping technique to introduce minor alloying of Co into Sn-58Bi solder alloys, providing new insights into enhancing the properties and performance of these solders. This new Sn-Bi-Co alloy has the potential to replace lead-containing solder alloy in low-temperature soldering.
Integrating eDNA metabarcoding and citizen science enhances avian ecological research
Authors: Padró Julián 
Published: July 2024

AbstractResearch Highlight: Bourbour et al., 2024. Feeding en route: Prey availability and traits influence prey selection by an avian predator on migration. Journal of Animal Ecology. Diet selection plays a key role in the eco‐evolutionary dynamics of animals, exhibiting substantial variability across species, environments and seasons. The complex interplay between movement capability, hunting strategies, habitat use, prey traits and availability shapes the foraging patterns of avian predators. However, detailed information on how these birds exploit their extensive territories remains limited. In this study, Bourbour et al. utilised a novel integration of eDNA metabarcoding and citizen science to explore predator–prey interactions between migrating sharp‐shinned hawks (Accipiter striatus) and an ephemeral avian prey community along North America's Pacific flyway. The research identified 1396 detections from the diet (65 species) of 588 migrating sharp‐shinned hawks. Hawks' diet composition correlated with prey abundance indices sourced from the eBird database throughout the migration season, highlighting the significant impact of prey availability—shaped by migration tendency, flocking behaviour, and habitat—on raptor‐songbird interactions. Notably, the study also found significant differences in prey size between male and female hawks, indicating that sexual dimorphism has led to diverse foraging strategies during migration. These findings underscore the potential of combining eDNA metabarcoding with citizen science to deepen our understanding of the foraging ecology of highly mobile and wide‐ranging birds, as well as to monitor complex and vast ecosystems.
