Evolution of 2D MoO3 Layer Structures on Pd(100): Interplay of Interfacial Interactions and Polarity

Abstract We explore the structural evolution of two-dimensional (2D) MoO3 films beyond the monolayer, which have been prepared by physical vapor deposition and post-oxidation onto a Pd(100) surface, and characterized by the tools of surface science and density functional theory (DFT) calculations. According to DFT, the most stable oxide layers are stoichiometric, and derive their energetic stability from the low cost of creating 2D freestanding layers from the orthorhombic bulk phase, good matching to Pd, and the particularly strong adhesion to the substrate. The observed 2D MoO3 layers are distinguished by well-ordered linear defects, such as domain boundaries in the monolayer, and misfit dislocations in the bilayer. Applying reactive oxidation preparation conditions results in the formation of ordered arrays of nanostructures, nanowires and nanoclusters, in the MoO3 bilayer. The formation of such linear structures is accounted for in the DFT by models of missing row defects of various orientations and stoichiometries. Their relative stability is rationalized in terms of the number of broken Mo-O bonds, the polar character of the nanostructure edges and the interaction strength with the Pd substrate. Comparison with similar WO3 layers on Pd(100) is provided.

Organosulfur Cathodes in Lithium Metal Batteries: Bridging the Gap between Fundamentals and Practical Applications

AbstractHigh‐specific energy sulfur‐based cathodes have attracted considerable interest in lithium batteries. Organosulfur cathodes offer inherent advantages of high element abundance and an extended cycling life, aligning with the evolving requirements of future energy storage devices. Over the past decade, research efforts have been devoted to optimizing electrochemical performance through the rich and tunable molecular structures of organosulfur compounds. To further advance the fundamental research and practical application of lithium‐organosulfur batteries, a systematical analysis of the correlation between the molecular structures and electrochemical mechanisms of organosulfur cathodes is imperative. This involves deriving the key parameters at the cell level and investigating the feasibility. In this review, the thermodynamics, reaction processes, and electrochemical kinetics of organosulfur cathodes, grounded in fundamental theories of electrochemistry and materials science are discussed. Expanding the insights, comparisons among elemental sulfur, organosulfur, and n‐type organic cathodes (e.g., carbonyl cathodes) are drawn. The gap between fundamentals and practical applications targeting 500 Wh kg−1 lithium organosulfur batteries is highlighted through energy density calculations and identification of key factors affecting pouch cells. Finally, potential strategies and prospects for the overall design of advanced lithium‐organosulfur batteries are proposed, considering both theoretical foundations and practical implementations.

Genomic surveillance strategy. Problems and perspectives

The topic of epidemiologic surveillance is one of the basic concepts in the theory and practice of epidemiologic science. In Russia, generalization of the accumulated factual material and theoretical developments have allowed us to formulate a number of provisions on the nature of the epidemic process. The pandemic of a new coronavirus infection has forced adjustments in all spheres of society, including the activities of the infectious disease epidemiological surveillance system, requiring the development and implementation of innovative solutions. Based on the experience of prompt response to the tasks set by the COVID-19 pandemic, the authors raised the problem of development and implementation of a system of molecular genetic monitoring for pathogens of emerging and re-emerging infections as a priority vector of epidemiological surveillance development. The introduction of modern molecular biological technologies for the identification of pathogens with epidemic potential, taking into account their genetic diversity, into the system of epidemiologic surveillance has been substantiated based on the experience of using platform solutions created by the Central Research Institute of Epidemiology of Rospotrebnadzor. The strategy of genomic epidemiologic surveillance as a powerful tool to ensure readiness for response measures and management of the epidemic process by implementing and adjusting preventive and anti-epidemic measures was developed. The Russian platform for aggregation of information on virus genomes (VGARus) developed at the Central Research Institute of Epidemiology of Rospotrebnadzor as a technological, scientific, organizational and infrastructural base of genomic epidemiological surveillance, acting as an interdepartmental consortium, has been introduced into practice. The efficiency of VGARus was shown to assess the mutational variability of SARS-CoV-2, the influence of evolutionary development of circulating pathogens on the characteristics of the epidemic process, the implementation of operational and retrospective analysis of morbidity and prediction of the spread of genetic variants of pathogens.

Religious coping and delinquent behaviors: Moderated mediation roles of religion affiliation and prosocial moral reasoning.

Religion has been shown to have a positive impact for developing adolescents; however, the processes underlying this relation are not well known. In his almighty prosocial theory, Anazonwu (Conceptualizing and testing almighty prosociality theory for a more peaceful world, SCOA Heritage Nigeria, 2017) proposed that the activation of learnt prosocial moral reasoning through religion enabled performance of prosocial peace behavior that will benefit society. Thus, religion coping enhances the development of prosocial reasoning which in turn propagate prosocial acts while reducing delinquent behaviors. Similarly, developmental system theory (Lerner, Developmental science, developmental systems, and contemporary theories of human development, John Wiley & Sons, 2006) assumed that in every individual three mechanisms: plasticity (potential to change), context (environment), and developmental regulation (learnable principles) interact to describe the direction of the transactions between individuals and their various embedded sociocultural context of development which will also determine other developmental outcomes. Based on these two theoretical assumptions, the present study examined whether prosocial moral reasoning (developmental regulation) was the mechanism in the negative correlation between religious coping (plasticity) and delinquent behaviors (outcome), and if religious affiliation(context) (Christianity and Islam) moderated these paths. We hypothesized that the link from prosocial moral reasoning to lower delinquent behaviors would be stronger for Muslim compared with Christian youth. These questions were tested among Nigerian adolescence, an important sample because of high interreligious and interethnic tension among youth in the country. 298 adolescents (Mean age = 15.03 years, SD = 1.76; male = 176, female = 122; 46.3% Muslim, 53.7% Christian) were sampled using questionnaires in senior secondary schools in Nigeria. Moderated mediation result shows that greater religious coping was linked with higher prosocial moral reasoning, which in turn predicted fewer delinquent behaviors. Religious coping interacted with religion affiliation to influence delinquent behavior; there was a stronger link between these two constructs for Muslim compared to Christian youth. Thus, interventions aiming to reduce youth delinquent behaviors should consider promoting prosocial moral reasoning, particularly among the various religions (i.e., Christian/Muslim) communities.

Strategies of Green Industrial Policy: How States Position Firms in Global Supply Chains

The resurgence of industrial policymaking—particularly for emerging low-carbon industries—challenges social science theories that expect such interventions from centralized states or suggest that different kinds of states specialize in various forms of innovation policy. Interventionist forms of industrial policy have made a comeback among liberal economies. Coordinated economies now make use of market-driven strategies. This paper argues that the new generation of industrial strategies is shaped by the industrial development challenges that policymakers face at the sectoral level. It proposes a new theoretical framework that distinguishes between the policy orientation (targeted or open-ended) and the central agents driving financial and technological decision-making (governments or firms). We show that the choice of strategy is shaped by the level of uncertainty and the position of the domestic industry in global supply chains, that is, whether global supply chains are emerging or mature and whether the domestic industry is an entrant or incumbent.

Application of theories in Library and Information Science research in Tanzania: A content analysis

Using a content analysis approach, this study assessed the application of theories in Library and Information Science (LIS) research in Tanzania. The study’s specific objectives encompassed the analysis of the utilization patterns of theories in LIS research conducted in Tanzania, the identification of predominant theories, the highlighting of specific areas within LIS research where theories have been extensively applied, and the assessment of the level of integration of theories into research. While Kalervo and Vakkari’s classification scheme of LIS research areas was used to identify specific research areas where theories have been applied most, seven categories of theory talk were utilized to evaluate the degree to which these theories have been incorporated into LIS research. The study’s findings reveal a growing inclination towards the use of theories among LIS researchers, albeit at a slow pace. The study has also shown that TAM and UTAUT theories are the most frequently utilized, with information-seeking research being the primary area incorporating theories among all identified research areas. The findings also suggest that while a significant portion of the analyzed articles fall under the major category of the Continuum of Theory Talk, implying substantial incorporation of theories, a small number of them encountered difficulties in effectively integrating theories. The study, therefore, suggests that LIS educators should also prioritize the theoretical aspect of research in their curriculum. This will help researchers improve their understanding of the subject matter, leading to more reliable and precise research.

This shows, there is 4 % and 7 % deviation from vehicle evidence speed and fuel consumption respectively.

Advancing Urban Water Autonomy: A Social Life Cycle Assessment of Rainwater Harvesting Systems in Mexico City

This study conducts a Social Life Cycle Assessment (S-LCA ) of Rainwater Harvesting Systems (RWHS) in Mexico City to evaluate their social performance. Given the city's pressing water scarcity, RWHS have become critical for promoting water autonomy and sustainable urban development. The research integrates quantitative data from surveys and interviews with RWHS users and organizational employees, along with qualitative analysis using the Product Social Impact Assessment (PSIA) approach. This methodology allows for a thorough examination of socio-environmental dynamics influenced by RWHS adoption. Our findings show high acceptance of RWHS among users and highlight progressive labor practices, underscoring RWHS's potential to transform urban water management. This study, the first to evaluate this ecotechnology through an S-LCA, identifies the need for a multidimensional approach to understand socio-economic and environmental intersections with water systems. It also underscores NGOs' role in facilitating technology transfer and adoption in urban communities. Recommendations include extending the S-LCA methodology to cover the entire RWHS lifecycle and incorporating broader social science theories to deepen understanding of water sustainability interventions. The results offer new insights into RWHS assessment, emphasizing the complexities of deploying decentralized water technologies in a mega-city and laying groundwork for policy recommendations that support sustainable, equitable water access.

Navigating political terrain: a comprehensive review of leadership theories in political science

Political science is increasingly focusing on the study of leadership factors in its field scope. Therefore, the primary objective of this article is to systematically analyze the use of leadership theories in scholarly publications of political science. This paper also underscores the lack of leadership theories or concepts in political science, offering insights to anyone interested in examining leadership in this academic discipline. This study introduces an alternative framework for analyzing leadership, specifically emphasizing political leadership. Thus, the question addressed in this study is: What leadership theories are applied to the study of political science? This study utilizes the systematic literature review approach, except for the Appraisal Quality stage, to examine political leadership theory and the notion of utilization as discussed in political science. The ROSE protocol is employed in this study due to its suitability for mapping and qualitative studies. Furthermore, PICo is used to formulate research questions in the context of this study. The results of this study, which involved the review of 75 papers, revealed the implementation of leadership theories and concepts in 15 distinct contexts or focus areas. The analysis of leadership in political science places significant emphasis on the dimensions of transformative and transactional leadership styles. Both leadership styles are frequently used in various research contexts. Overall, the prevalence of transformative and transactional leadership theories in political science can be understood as a reflection of the constraints political scientists face in comprehending the nature of leadership within a political context from a scientific standpoint.

Implementation of Health IT for Cancer Screening in US Primary Care: Scoping Review.

A substantial percentage of the US population is not up to date on guideline-recommended cancer screenings. Identifying interventions that effectively improve screening rates would enhance the delivery of such screening. Interventions involving health IT (HIT) show promise, but much remains unknown about how HIT is optimized to support cancer screening in primary care. This scoping review aims to identify (1) HIT-based interventions that effectively support guideline concordance in breast, cervical, and colorectal cancer screening provision and follow-up in the primary care setting and (2) barriers or facilitators to the implementation of effective HIT in this setting. Following scoping review guidelines, we searched MEDLINE, CINAHL Plus, Web of Science, and IEEE Xplore databases for US-based studies from 2015 to 2021 that featured HIT targeting breast, colorectal, and cervical cancer screening in primary care. Studies were dual screened using a review criteria checklist. Data extraction was guided by the following implementation science frameworks: the Reach, Effectiveness, Adoption, Implementation, and Maintenance framework; the Expert Recommendations for Implementing Change taxonomy; and implementation strategy reporting domains. It was also guided by the Integrated Technology Implementation Model that incorporates theories of both implementation science and technology adoption. Reporting was guided by PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews). A total of 101 studies met the inclusion criteria. Most studies (85/101, 84.2%) involved electronic health record-based HIT interventions. The most common HIT function was clinical decision support, primarily used for panel management or at the point of care. Most studies related to HIT targeting colorectal cancer screening (83/101, 82.2%), followed by studies related to breast cancer screening (28/101, 27.7%), and cervical cancer screening (19/101, 18.8%). Improvements in cancer screening were associated with HIT-based interventions in most studies (36/54, 67% of colorectal cancer-relevant studies; 9/14, 64% of breast cancer-relevant studies; and 7/10, 70% of cervical cancer-relevant studies). Most studies (79/101, 78.2%) reported on the reach of certain interventions, while 17.8% (18/101) of the included studies reported on the adoption or maintenance. Reported barriers and facilitators to HIT adoption primarily related to inner context factors of primary care settings (eg, staffing and organizational policies that support or hinder HIT adoption). Implementation strategies for HIT adoption were reported in 23.8% (24/101) of the included studies. There are substantial evidence gaps regarding the effectiveness of HIT-based interventions, especially those targeting guideline-concordant breast and colorectal cancer screening in primary care. Even less is known about how to enhance the adoption of technologies that have been proven effective in supporting breast, colorectal, or cervical cancer screening. Research is needed to ensure that the potential benefits of effective HIT-based interventions equitably reach diverse primary care populations.

Incorporating Evidence-Based Gamification and Machine Learning to Assess Preschool Executive Function: A Feasibility Study

Computerized assessments and digital games have become more prevalent in childhood, necessitating a systematic investigation of the effects of gamified executive function assessments on performance and engagement. This study examined the feasibility of incorporating gamification and a machine learning algorithm that adapts task difficulty to individual children’s performance into a traditional executive function task (i.e., Flanker Task) with children ages 3–5. The results demonstrated that performance on a gamified version of the Flanker Task was associated with performance on the traditional version of the task and standardized academic achievement outcomes. Furthermore, gamification grounded in learning science and developmental psychology theories applied to a traditional executive function measure increased children’s task enjoyment while preserving psychometric properties of the Flanker Task. Overall, this feasibility study indicates that gamification and adaptive machine learning algorithms can be successfully incorporated into executive function assessments with young children to increase enjoyment and reduce data loss with developmentally appropriate and intentional practices.

Physicochemical Properties and Rheological Behavior of Gluten-Free Flour Blends for Bakery Products

Purpose: The general aim of the study was to investigate the physicochemical properties and rheological behavior of gluten-free flour blends for bakery products. Methodology: The study adopted a desktop research methodology. Desk research refers to secondary data or that which can be collected without fieldwork. Desk research is basically involved in collecting data from existing resources hence it is often considered a low cost technique as compared to field research, as the main cost is involved in executive’s time, telephone charges and directories. Thus, the study relied on already published studies, reports and statistics. This secondary data was easily accessed through the online journals and library. Findings: The findings reveal that there exists a contextual and methodological gap relating to physicochemical properties and rheological behavior of gluten-free flour blends for bakery products. Preliminary empirical review revealed that hydrocolloids such as xanthan gum and guar gum significantly improved dough viscoelasticity, texture, and stability, while the efficacy of carrageenan was limited. Optimizing the concentrations and combinations of hydrocolloids was deemed essential for achieving superior rheological properties. Additionally, the study emphasized the importance of considering physicochemical properties alongside rheological behavior to develop gluten-free bakery products that meet consumer expectations. Overall, the findings highlighted the complexity of gluten-free baking and underscored the need for a multidimensional approach integrating physicochemical analyses with rheological assessments. Unique Contribution to Theory, Practice and Policy: The Food Material Science theory, Rheology theory and Biopolymer theory may be used to anchor future studies on physicochemical properties and rheological behavior of gluten-free flour blends. The study provided valuable recommendations. It contributed to theory by exploring the effects of various hydrocolloids on dough properties, highlighting the importance of xanthan gum and guar gum in improving dough viscoelasticity. In practice, it suggested optimizing hydrocolloid concentrations for superior rheological properties in gluten-free bakery products. Moreover, the study offered insights for policy-makers regarding the formulation of gluten-free bread to meet quality standards. Overall, the research advanced understanding in the field and provided practical guidelines for industry and policymakers.

Preparation and Structural Analysis of a Water-Soluble Aminated Lignin.

Lignin is insoluble in water, thereby limiting its use in the synthesis of adhesives. Therefore, in this study, an aminated lignin compound was prepared through a lignin amination reaction to increase the amount of raw lignin material that can be used in the synthesis of adhesives; moreover, structural analysis was conducted. The main result of this was the introduction of amino groups into phenolic hydroxyl groups in the hydrolyzing lignin from the raw lignin materials, thus generating the product of aminated lignin. The resulting particle sizes were about 100 nm, the average molecular weight was 57,627 g/mol, and the water solubility of the aminated lignin was about 0.45 g/100 mL. Therefore, the water solubility of raw lignin was greatly improved. The proposed reaction mechanism of phenolic hydroxyl groups and carboxylic acid groups in lignin is a reaction with ammonia molecules; thus, the successful introduction of amino groups generated the aminated lignin compounds. Hence, this article enriches the scientific theory of lignin reactions and provides a reference for the widespread application of raw lignin materials in the field of adhesives.

Target-constrained Bidirectional Planning for Generation of Target-oriented Proactive Dialogue

Target-oriented proactive dialogue systems aim at leading conversations from a dialogue context toward a pre-determined target, such as making recommendations on designated items or introducing new specific topics. To this end, it is critical for such dialogue systems to plan reasonable actions to drive the conversation proactively, and meanwhile, to plan appropriate topics to move the conversation forward to the target topic smoothly. In this work, we mainly focus on effective dialogue planning for target-oriented dialogue generation. Inspired by decision-making theories in cognitive science, we propose a novel target-constrained bidirectional planning (TRIP) approach, which plans an appropriate dialogue path by looking ahead and looking back. By formulating the planning as a generation task, our TRIP bidirectionally generates a dialogue path consisting of a sequence of <action, topic> pairs using two Transformer decoders. They are expected to supervise each other and converge on consistent actions and topics by minimizing the decision gap and contrastive generation of targets. Moreover, we propose a target-constrained decoding algorithm with a bidirectional agreement to better control the planning process. Subsequently, we adopt the planned dialogue paths to guide dialogue generation in a pipeline manner, where we explore two variants: prompt-based generation and plan-controlled generation. Extensive experiments are conducted on two challenging dialogue datasets, which are re-purposed for exploring target-oriented dialogue. Our automatic and human evaluations demonstrate that the proposed methods significantly outperform various baseline models.

Using formal theory in evaluation – What is it and how is it used?

Little information is available about how formal, social science theory has been used in outcome evaluations. This gap exists in debates about what role theory has in evaluation. To help address this, we need to understand variation in formal theory use in real-world practice. This research applied systematic qualitative coding to identify and classify patterns of theory use, followed by qualitative comparative analysis. The terms describing theory are defined and formal theory is differentiated from other kinds of theory, such as program theory. The study found instances of borrowing and repurposing theoretical material in a cohesive sample of 17 outcome evaluation reports covering programs addressing complex social problems, drawn from cross-cultural contexts. Theory was mostly used for post hoc explanation and less often used upfront in framing, design and conduct of evaluation. The concrete approach in the literature of applying formal theory to measure and explain causal pathways to behavioural outcomes was found, as was layered use of a range of theoretical material. This article offers insights that may assist evaluators to undertaken more sophisticated and reflective approaches to using theory. Thinking about ways we use theory could form part of the tool-kit of techniques available to evaluation practice.

Polychronicity: Matching Time Styles and Task Types. Some Evidence from a Student Experiment

Polychronicity, an under-researched dimension of diversity, refers to the degree to which a person likes to engage in several tasks at once. Common sense, scientific theory and initial evidence suggest that individuals will perform better when faced with a job whose demands on multi-tasking match their individual time styles. This paper reports on an experiment among students to test the performance effect of the person-job-fit with respect to polychronicity. Unlike prior research, our experimental conditions focus on the mode of allocating scarce time among multiple tasks. The preliminary results confirm a performance premium in case of a match between time styles and task types.

Minimizing Entropy and Complexity in Creative Production from Emergent Pragmatics to Action Semantics

New insights into intractable industrial challenges can be revealed by framing them in terms of natural science. One intractable industrial challenge is that creative production can be much more financially expensive and time consuming than standardized production. Creative products include a wide range of goods that have one or more original characteristics. The scaling up of creative production is hindered by high financial production costs and long production durations. In this paper, creative production is framed in terms of interactions between entropy and complexity during progressions from emergent pragmatics to action semantics. An analysis of interactions between entropy and complexity is provided that relates established practice in creative production to organizational survival in changing environments. The analysis in this paper is related to assembly theory, which is a recent theoretical development in natural science that addresses how open-ended generation of complex physical objects can emerge from selection in biology. Parallels between assembly practice in industrial production and assembly theory in natural science are explained through constructs that are common to both, such as assembly index. Overall, analyses reported in the paper reveal that interactions between entropy and complexity underlie intractable challenges in creative production, from the production of individual products to the survival of companies.

How can a behavioral economics lens contribute to implementation science?

BackgroundImplementation science in health is an interdisciplinary field with an emphasis on supporting behavior change required when clinicians and other actors implement evidence-based practices within organizational constraints. Behavioral economics has emerged in parallel and works towards developing realistic models of how humans behave and categorizes a wide range of features of choices that can influence behavior. We argue that implementation science can be enhanced by the incorporation of approaches from behavioral economics.Main bodyFirst, we provide a general overview of implementation science and ways in which implementation science has been limited to date. Second, we review principles of behavioral economics and describe how concepts from BE have been successfully applied to healthcare including nudges deployed in the electronic health record. For example, de-implementation of low-value prescribing has been supported by changing the default in the electronic health record. We then describe what a behavioral economics lens offers to existing implementation science theories, models and frameworks, including rich and realistic models of human behavior, additional research methods such as pre-mortems and behavioral design, and low-cost and scalable implementation strategies. We argue that insights from behavioral economics can guide the design of implementation strategies and the interpretation of implementation studies. Key objections to incorporating behavioral economics are addressed, including concerns about sustainment and at what level the strategies work.ConclusionScholars should consider augmenting implementation science theories, models, and frameworks with relevant insights from behavioral economics. By drawing on these additional insights, implementation scientists have the potential to boost efforts to expand the provision and availability of high quality care.

Implementation of Food is Medicine Programs in Healthcare Settings: A Narrative Review.

Food is Medicine (FIM) programs to improve the accessibility of fruits and vegetables (FVs) or other healthy foods among patients with low income and diet-related chronic diseases are promising to improve food and nutrition security in the United States (US). However, FIM programs are relatively new and implementation guidance for healthcare settings using an implementation science lens is lacking. We used a narrative review to describe the evidence base on barriers and facilitators to FIM program integration in US healthcare settings following the Exploration, Preparation, Implementation, and Sustainment (EPIS) Framework. Evidence surrounding the EPIS Inner Context was a focus, including constructs Leadership, Organizational Characteristics, Quality and Fidelity Monitoring and Support, Organizational Staffing Processes, and Individual Characteristics. Peer-reviewed and grey literature about barriers and facilitators to FIM programs were of interest, defined as programs that screen and refer eligible patients with diet-related chronic disease experiencing food insecurity to healthy, unprepared foods. Thirty-one sources were included in the narrative review, including 22 peer-reviewed articles, four reports, four toolkits, and one thesis. Twenty-eight sources (90%) described EPIS Inner Context facilitators and 26 sources (84%) described FIM program barriers. The most common barriers and facilitators to FIM programs were regarding Quality and Fidelity Monitoring and Support (e.g., use of electronic medical records for tracking and evaluation, strategies to support implementation) and Organizational Staffing Processes (e.g., clear delineation of staff roles and capacity); although, barriers and facilitators to FIM programs were identified among all EPIS Inner Context constructs. We synthesized barriers and facilitators to create an EPIS-informed implementation checklist for healthcare settings for use among healthcare organizations/providers, partner organizations, and technical assistance personnel. We discuss future directions to align FIM efforts with implementation science terminology and theories, models, and frameworks to improve the implementation evidence base and support FIM researchers and practitioners.
