Mediation in the Relation of Orthographic Processing on the Lexical and Sublexical Level with Reading and Spelling Skills. A Large Cross-Sectional Study in Elementary School Children in Germany

ABSTRACT Purpose Two types of orthographic knowledge were examined: i) knowledge of permissible letter combinations (general orthographic knowledge) and ii) knowledge of whole words (word-specific orthographic knowledge), to gain further insights into the relationship of general and word-specific orthographic knowledge with literacy skills. Method Mediation models were estimated using a sample of 2,636 3rd and 4th grade children (50.6% female, ethnic backgrounds were not surveyed) to examine whether general orthographic knowledge predicts reading fluency and spelling performance and whether this path is mediated by word-specific orthographic knowledge. Using confirmatory factor analyses (CFA), we examined whether the responses to correctly spelled words/legal letter patterns and pseudohomophones/illegal letter patterns in word-specific and general orthographic knowledge tasks were generated by separate latent constructs. Results Our results confirm that word-specific orthographic knowledge is a facilitatory mediator in the relationship between general orthographic knowledge and literacy skills. The relationship of general and word-specific orthographic knowledge with literacy skills varies by item type, with a tendency toward higher correlations between literacy skills with pseudohomophones (vs words) and illegal (vs legal) pseudowords, which is in line with the two-factor solution of the CFA. Conclusion From a theoretical perspective, we conclude that general orthographic knowledge facilitates orthographic learning of words. From a methodological perspective, we encourage future researchers to distinguish between targets and foils in orthographic decision tasks.

Material Engineering Strategies for Efficient Hydrogen Evolution Reaction Catalysts.

Water electrolysis, a key enabler of hydrogen energy production, presents significant potential as a strategy for achieving net-zero emissions. However, the widespread deployment of water electrolysis is currently limited by the high-cost and scarce noble metal electrocatalysts in hydrogen evolution reaction (HER). Given this challenge, design and synthesis of cost-effective and high-performance alternative catalysts have become a research focus, which necessitates insightful understandings of HER fundamentals and material engineering strategies. Distinct from typical reviews that concentrate only on the summary of recent catalyst materials, this review article shifts focus to material engineering strategies for developing efficient HER catalysts. In-depth analysis of key material design approaches for HER catalysts, such as doping, vacancy defect creation, phase engineering, and metal-support engineering, are illustrated along with typical research cases. A special emphasis is placed on designing noble metal-free catalysts with a brief discussion on recent advancements in electrocatalytic water-splitting technology. The article also delves into important descriptors, reliable evaluation parameters and characterization techniques, aiming to link the fundamental mechanisms of HER with its catalytic performance. In conclusion, it explores future trends in HER catalysts by integrating theoretical, experimental and industrial perspectives, while acknowledging the challenges that remain.

Theoretical Perspective on the Design of Surface Frustrated Lewis Pairs for Small-Molecule Activation.

The excellent reactivity of frustrated Lewis pairs (FLP) to activate small molecules has gained increasing attention in recent decades. Though the development of surface FLP (SFLP) is prompting the application of FLP in the chemical industry, the design of SFLP with superior activity, high density, and excellent stability for small-molecule activation is still challenging. Herein, we review the progress of designing SFLP by surface engineering, screening natural SFLP, and the dynamic formation of SFLP from theoretical perspectives. We highlight the breakthrough in fine-tuning the activity, density, and stability of the designed SFLP studied by using computational methods. We also discuss future challenges and directions in designing SFLP with outstanding capabilities for small-molecule activation.

The influence of linguistic profiling on perceived employability: a new application of the systems theory framework of career development

PurposeThe purpose of this paper is to clarify the influence of linguistic profiling on perceived employability. In doing so, we recognize multiple factors that can contribute to this relationship. Using the systems theory framework (STF) of career development, we categorize these factors based on whether they primarily reside within the societal system, the organizational system, or the individual system. Subsequently, we construct and present an open systems model that depicts the influence of linguistic profiling on perceived employability in context with other societal, organizational and individual factors.Design/methodology/approachThe STF provides a theoretical perspective on how to contextualize linguistic profiling and perceived employability within the scope of career development. We employed an integrative literature review method to locate existing research studies that investigated the influences of linguistic profiling and perceived employability. The literature search process, coupled with inclusion and exclusion criteria, resulted in 46 publications retained for analysis.FindingsFindings provided evidence of language ideologies that contribute to linguistic profiling globally. Linguistic profiling usually results in reduced perceived employability. There was variation in the research findings based on the context of the research studies. The context consisted of the societal, organizational and individual systems in which the research study was conducted. Findings supported our construction of an open systems model of the influence of linguistic profiling on perceived employability, which is rooted in the STF.Originality/valueThis study highlights the negative influence of linguistic profiling on perceived employability. It also demonstrates how the STF can be used to contextualize the linguistic profiling problem within societal and organizational systems.

Building College Education Management in the New Era: Theoretical Discussion and Model Construction Based on New Quality Productivity

This study analyses the use of new quality productivity theory in higher education management and develops a framework called the "multi-dimensional collaborative innovation management model" to tackle the challenges of globalisation and information technology. This concept combines the three dimensions of scientific and technological innovation, management innovation, and system innovation to promote effective resource allocation, improve educational quality and efficiency, and increase the education system's adaptability. This study uses mixed-methods research to verify the model's effectiveness in practical educational management as well as to present fresh theoretical perspectives and practical tactics for cultivating high-qualified talents who will satisfy the needs of future society.

The forced battle between peer-review and scientometric research assessment: Why the CoARA initiative is unsound

Abstract Endorsed by the European Research Area, a Coalition for Advancing Research Assessment (CoARA), primarily composed of research institutions and funders, was established in 2022. Its mission is to reform research assessment, emphasizing a shift towards qualitative judgment. This study examines the CoARA initiative from theoretical, practical, and applicative perspectives, exploring its implications. The manuscript questions a standardized way to evaluate research suitable in every context. Through empirical evidence and internal logical arguments, it challenges the supremacy of qualitative over quantitative methods in terms of robustness, accuracy, validity, functionality, and time and cost convenience in STEMM research assessment. The aim is to clear up common misunderstandings and offer insights to policymakers and decision-makers in charge of defining how research should be evaluated.

‘It’s a who-you-know thing’: interactional fraud prevention in non-bank check cashing

Abstract This article demonstrates how presentations of self and the information conveyed within them are a conduit for risk evaluation within the marketplace. Using the case of check cashing, it investigates customer screening within the Detroit area’s most prevalent non-bank check cashing businesses, which are not standalone check cashing outlets but rather corner convenience and liquor stores known as ‘party stores’. Without algorithmic techniques based on hard or quantitative data, how do owners screen customers to prevent fraud? Drawing on 35 months of ethnographic fieldwork, this article uncovers two strategies toward this end: (a) gathering private information about customers through small talk; and (b) assessing check cashers’ presentations of self. Analyzing check cashing and fraud in this setting speaks to theoretical perspectives of risk evaluation by presenting a case of interactional fraud prevention, which highlights the interpersonal, interactional mechanisms through which soft information is exchanged and assessed in ex ante screening.

Inclusive and Special Education Policy in Nepal: Reality, Rhetoric and Contradiction

ABSTRACT This study investigated inclusive and special education policy in Nepal. This paper employs social constructionism and discourse analysis as theoretical perspectives. This study is informed by the findings of the author’s doctoral research. Data were collected from a selected key policy document between 1970 and 2020. Discourses of disability was used as a methodology to examine how these policies construct the meaning of disability and inclusive education. The findings of this study demonstrated that Nepalese inclusive and special education policies have been influenced by the medical or deficit and social or human rights model discourse of disability. This article identified that the educational policies of Nepal were consistent and in variation between these two discourses of disability. This study found that inclusive education policies had rhetoric, contradictions and tensions within the policy documents. Limitations and recommendations of this research were also discussed.

Synergies of affordances and place-based relationality in Forest School practice: implications for socio-emotional well-being

Research shows that the human-nature relationship positively impacts human well-being. Forest School (FS) practice offers young children a structured program of nature connection through activities, aiming to enhance their self-esteem and social skills. FS is now adapted in countries such as Australia, Canada and New Zealand where a unique cultural interface occurs between European settlers and Indigenous peoples. Responding to socio-cultural diversities, geographical contexts, and the traditional ecological knowledges, FS needs to go beyond play pedagogy and incorporate theoretical perspectives that promote human-nature relationship in local context-specific environments. We argue that the synergies between Western perspectives on affordances perceived in person-environment relationship and Indigenous place-based relationality perspective provide a more suitable approach for developing reciprocal relationships between FS participants and land/place/nature. We propose that the synergies between affordances perceived in FS and place-based relationality cultivated in participants will enhance social and emotional well-being. We call for specific research investigating such synergies supporting participant well-being. Future research on FS practice should be directed toward initiating and exploring co-designed studies by Indigenous and non-Indigenous researchers incorporating methodologies that study participant experience as well as evaluating the impact of FS programs embedding affordances and place-based relationality perspectives.

The influence of affective processing on phishing susceptibility

ABSTRACT The heightened sophistication of phishing attacks results in billions of dollars of financial losses, loss of intellectual property, and reputational damage to organisations. Past work examining determinants of phishing susceptibility has been dominated by cognitive theoretical perspectives. However, recent research has also revealed the importance of emotion in phishing susceptibility. This study expands our understanding of phishing susceptibility by adopting an affective lens. Using an integrative perspective of emotion, we build on the Affective Infusion Model (AIM) to predict the effects of valence, certainty, and arousal on phishing susceptibility. We pilot our manipulations (N = 241) and then test our hypotheses using a mock phishing experiment (N = 474) in which phishing messages are sent directly to participant inboxes. We demonstrate that messages inducing positive valence and low certainty result in higher phishing susceptibility. This study contributes to phishing literature by illuminating the critical role that emotion plays in altering recipients’ susceptibility in the processing of phishing messages and has implications for scholars, practitioners, and organisations.

Demographics and Fives Cs of PYD as Predictors of the Domains of Contribution among Youth in Nigeria

In recent times, research has focused on positive youth development (PYD) amidst the deficits of youth. However, little is known about PYD and its potential to predict social engagement. Thus, this study aimed to examine the presence of the 5Cs of PYD (competence, confidence, connection, character, and caring) and its difference in gender and prediction to contribution, specifically social engagement among family, peers, schools, and community. The sample size consisted of Nigerian youth in University (N = 394, Mage = 18.42, SD = 1.02). The PYD framework served as the theoretical perspective underpinning the study. Questionnaires were administered using the 5Cs model of PYD and contribution items. Data were analysed for descriptive, correlations, and hierarchical regression to examine the predictors of contribution while controlling for demographics. The results showed greater scores in competence, connection, and character for women. Competence and connection (β = 0.56, p < 0.05) specifically had significantly independent associations with community volunteerism. While the findings highlight the Cs experienced and predictive values among each variable in the Nigerian context, future research could consider how each domain of the 5Cs holistically promotes contribution equally in males and females among diverse Nigerian youth. The research has implications for research, policy, and practice.

Double transition of young migrants in Luxembourg: vulnerable, resilient and empowering integration trajectories in the period of youth

Migrant integration trajectories have become more complex, open, uncertain, and continuously changing, over time. For young migrants, their integration endeavour intersects with their process of transition to adulthood, a double transition that poses additional challenges. Recent theoretical perspectives such as “liquid integration” aim at focusing on the dynamic, processual, and temporal nature of migrant integration. The present article focuses on the dynamic interplay of obstacles and enablers that, over time, interact to construct complex, often non-linear, and open-ended integration and coming of age trajectories of young migrants (aged from 18 to 30 years) coming from outside the European Union (EU) to EU countries. Empirical results from the H2020 MIMY (Empowerment through liquid Integration of Migrant Youth in vulnerable conditions) research project in Luxembourg will be presented. In order to address the goal of the research, qualitative data were gathered by means of N = 38 interviews with young migrants with different migratory paths, characteristics and experiences, and specifically included: young migrants from non-EU Portuguese-speaking countries (N = 16), refugees living in reception centres (N = 15), migrants who since arriving in Luxembourg have become publicly visible (N = 7). Content analysis of the interviews allowed a twofold purpose: (1) capturing the unfolding of intersectional integration obstacles that over time play a decisive role in the building of conditions of vulnerability of the double transition under analysis; (2) capturing the multidimensional resources that interactively build up to give rise to resilient and empowering integration and coming of age experiences. The identification of decisive multidimensional obstacles and resources present in the integration endeavour during the process of coming of age allowed us to capture differentiated routes of vulnerability, on the one hand, and resilience/ empowerment on the other. Key ingredients of both vulnerable and more resilient and empowering integration and coming of age trajectories are identified as well as their relational dynamics, enabling to address key challenges for the resilience and empowerment of young migrants in the process of negotiating their transition to adulthood amidst their integration challenges in the Luxembourgish society.

Trigger mechanism centralized but discursive frame fragmented: China as a case for studying populism at the grassroots level in the social media age

ABSTRACT While most research focuses on top-down populism practiced by political actors in democratic countries, we paid attention to populist phenomena at the grassroots level in an authoritarian context. Specifically, we proposed a perspective of investigating populist discourse embedded in public opinion and adopted a fine-grained discursive frame approach to study Chinese online populism. Using large-scale social media data around trending events and employing cutting-edge computational semantic analysis methods, we discovered that economic anxiety is central to the trigger mechanism of Chinese online populism, and the specific populist discourse is fragmented in terms of ideological resources, cultural toolboxes, and semantic structure. This study not only provides a more comprehensive understanding of contemporary Chinese populism phenomena, but it also contributes to global populism research by providing valuable empirical evidence in authoritarian contexts and broadening the theoretical perspective of studying populism at the grassroots level.

Relationship between the presence of meaning in life and sleep quality: A moderated chain-mediation model.

Sleep is a vital component of health; however, sleep issues are particularly prominent among college students. Identifying protective factors for sleep among college students is of paramount importance. To investigate the mechanisms behind the association between the presence of meaning in life (PML) and sleep quality, we conducted two questionnaire surveys (separated by an interval of 6 months) with 5660 college students to collect longitudinal data. The results show that PML predicted sleep quality and that this relationship was influenced by the mediating effect of depression and the chain mediating effect of coping style and depression; further, the search for meaning in life played a moderating role in the chain mediation model. This study offers new theoretical perspectives on the protective factors of sleep quality and provides empirical insights useful for improving sleep health among college students.

Origins of Ligand-Controlled Stereoselective Polymerization of ortho-Methoxystyrene by Rare-Earth Catalysts: A Theoretical Perspective.

The stereoselective polymerization of polar vinyl monomers has recently received much attention due to their excellent physicochemical properties. Over the past decade, breakthroughs have been achieved in this field by rare-earth catalysts. However, the mechanistic origins of those stereoselective polymerizations still remain unclear. Herein, stereoselective polymerization of ortho-methoxystyrene (oMOS) by several representative rare-earth catalysts bearing different ligands (i.e., η5-C5Me5, pyridinyl-methylene-fluorenyl, quinolyl-anilido, β-diketiminato) were systematically investigated by density functional theory (DFT) calculations. After achieving agreement between the calculations and experiments, we focused on discussing the role of ligands in controlling stereoselectivity. Our results reveal that the stereoregularity of oMOS polymerization is mainly controlled by the steric effect of the catalyst-monomer structures. Specifically, the type of ligand influences the orientation and configuration of the inserting monomer, thereby affecting the tacticity of the polymers. In the cases of η5-C5Me5-, pyridinyl-methylene-fluorenyl, and quinolyl-anilido-ligated yttrium catalysts, we observe consistent insertion directions and alternating insertion sides of oMOS monomers, leading to syndiotactic selectivity. The opposite insertion directions and the alternating insertion sides of oMOS monomers were observed in the case of the β-diketiminato yttrium catalyst, leading to isotactic selectivity. These findings reported here offer valuable insights into the role of ligands in controlling stereoselectivity in rare-earth catalyzed coordination polymerization of polar vinyl monomers, thus providing guidance for the rational design of new ligands for stereospecific polymerization of polar monomers in the future.

Incorporation of adaptive compression into a GPU parallel computing framework for analyzing large-scale vessel trajectories

Automatic Identification System (AIS) offers a wealth of vessel navigation data, which underpins research in maritime data mining, situational awareness, and knowledge discovery within the realm of intelligent transportation systems. The flourishing marine industry has prompted AIS satellites and base stations to generate massive amounts of vessel trajectory data, escalating both data storage and calculation costs. The conventional Douglas-Peucker (DP) algorithm used for trajectory compression sets a uniform threshold, which hampers effective compression. Additionally, compressing and accelerating the computation of large datasets poses a significant challenge in real-world applications. To address these limitations, this paper aims to develop a new Graphics Processing Unit (GPU) parallel computing and compression framework that enables the acceleration of the optimal threshold calculation for each trajectory automatically in maritime big data mining. It achieves this by incorporating a new Adaptive DP with Speed and Course (ADPSC) algorithm, which utilizes the dynamic navigation characteristics of different vessels. It can effectively solve the associated computational time cost concern when using the ADPSC algorithm to compress vast trajectory datasets in the real world. Additionally, this paper proposes a novel evaluation metric for assessing compression efficacy based on the Dynamic Time Warping (DTW) method. Comprehensive experiments encompass vessel trajectory datasets from three representative research areas: Tianjin Port, Chengshan Jiao Promontory, and Caofeidian Port. The experimental results demonstrate that 1) the newly developed ADPSC method outperforms in terms of compression, and 2) the designed GPU parallel computing framework can significantly shorten the compression time for extensive datasets. The GPU-accelerated compression methodology not only minimizes storage and transmission costs for data from both manned and unmanned vessels but also enhances data processing speed, supporting real-time decision-making. From a theoretical perspective, it provides the key to the puzzle of realizing the real-time anti-collision of manned and unmanned ships, particularly in complex waters. It hence makes significant contributions to maritime safety in the autonomous shipping era.

Generational Differences in Sustainable Consumption Behavior among Chinese Residents: Implications Based on Perceptions of Sustainable Consumption and Lifestyle

To deal with the challenges posed by generational differences in China’s sustainable consumption transition, this study’s pioneers using a mixed-methods approach with data mining and literature research to classify Chinese residents into four generations based on the sustainable consumption perspective. We developed a conceptual model of generational differences and conducted an empirical study using structured interviews with a multi-stage random sampling approach. The results highlight significant differences and distinct influencing mechanisms among the four generations regarding perceptions of sustainable consumption, lifestyle, and sustainable consumption behavior. Based on this, multi-generational differentiated green marketing strategies, green product development and green marketing practices, as well as consumer education systems and strategies for stakeholders including the government, enterprises, and society are proposed. The findings contribute to advancing theoretical perspectives in sustainable consumption research, serving as a valuable reference for sustainable consumption research worldwide.

Modelling the Combined Effect of Green Leadership and Human Resource Management in Moving to Green Supply Chain Performance Enhancement in Saudi Arabia

Previous research has been limited in examining the causal relationship between green transformational leadership (GTL) and green supply chain management (GSCM), with the intermediary influence of green human resource management (GHRM), within the pharmaceutical sector of the Kingdom of Saudi Arabia (KSA). This gap persisted despite the recognition in Saudi Vision 2030 of logistics, specifically, supply chain management (SCM), as fundamental to the national development agenda, given that contemporary competitiveness lies in the efficacy of supply chains (SCs) rather than individual companies. Moreover, the achievement of economic progress hinges significantly on how well these accomplishments align with sustainability demands and obstacles. This paper aims to investigate the extent to which GTL fosters GRHM practices to enhance the maturity of GSCM performance in the pharmaceutical industry in the KSA. In other words, the research goal is to explain the variance of GSCM due to GHRM and GTL. Drawing upon the Resource-Based View (RBV) and the Ability–Motivation–Opportunity theory (AMO), GTL can enhance many aspects of GHRM, such as employee performance measurement, training content design, recruitment criteria, and green-based rewards policies, which positively influence GSCM practices. The methodology employed is deductive and translated into a questionnaire derived from a comprehensive review of the existing literature. This questionnaire was subsequently tested through the collection of 111 responses from pharmaceutical companies operating in the KSA. The results show the critical effects of GTL and GHRM on GSCM in this sector. The research provides fresh theoretical perspectives and actionable recommendations based on the outcomes. As for originality, this research explores the contribution of transformational leadership and green human resource management in enhancing SC sustainability. The research provides directions for future research to investigate the mediating or moderating impacts of other significant factors, such as green thinking or eco-friendly behaviour, on SCM sustainability. As for practical implications, this research came up with an in-depth understanding of SC managers and professionals regarding their practices related to sustainability.

The local governance of Swedish schools in light of a new educational policy landscape empirical exploration and theoretical elaboration

ABSTRACT In the Nordic curriculum theory (CT) tradition, questions linked to educational change and school governance have long been a crucial research issue. However, despite several decades of decentralized school systems, local school governance has been a highly neglected field of research. Considering the changing landscape of school governance in terms of re-centralization, where the state’s aim is to take stronger control of school outcomes, the conditions for local school governance have changed. Based on results from two research projects in two Swedish municipalities, and from a neo-institutional theoretical perspective, the aim of this article is to contribute to the CT research field by exploring and theorizing on local school governance. Four management strategies that local educational authorities (LEAs) employed to manage the schools could be distinguished: local school management via i) data use, ii) the standardization and formalization of schools’ quality assurance processes and routines, iii) quality dialogues, iv) professional learning and best practices. These management strategies and activities were mostly organized, and conducted within the scope of the LEAs’ quality assurance systems and were primarily built on normative and cultural – cognitive elements. A way to conceptualize this form of governance is through the concept of ‘local quality management’.
