A novel approach to study ascorbic acid oxidation using hexavalent chromium species—theoretical and practical perspectives of the use of potentiometric titration technique

AbstractThis paper highlights the advantages of using the potentiometric titration technique as a valuable tool for studying the oxidation reaction of ascorbic acid by hexavalent chromium species in aqueous solutions. Particular attention was paid to the method of determining diagnostic points allowing the quantification of ascorbic acid in the sample under study. Additionally, the influence of experimental conditions, specifically the pH of the system and the concentration of the reactants, on the type of hexavalent chromium species involved in the interaction with ascorbic acid was analyzed. It has been shown that the method presented provides a simple, cost-effective, and rapid tool that can be widely used for the direct determination of ascorbic acid.

Analysis of Claim Frequency and Severity in Auto Insurance Using Generalized Linear Models in Philippines

Abstract Purpose: The aim of the study was to analyze the analysis of claim frequency and severity in auto insurance using generalized linear models in Philippines. Methodology: This study adopted a desk methodology. A desk study research design is commonly known as secondary data collection. This is basically collecting data from existing resources preferably because of its low cost advantage as compared to a field research. Our current study looked into already published studies and reports as the data was easily accessed through online journals and libraries. Findings: The analysis of claim frequency and severity in auto insurance using Generalized Linear Models (GLMs) in the Philippines revealed that various factors, including driver demographics, vehicle characteristics, and geographic location, significantly impact the likelihood and severity of claims. The GLM approach effectively modeled these relationships, providing insights into risk factors that contribute to higher claim rates and costs. The findings suggest that younger drivers and those in urban areas tend to have higher claim frequencies, while larger vehicles and those with higher engine capacities are associated with more severe claims. Unique Contribution to Theory, Practice and Policy: Utility Theory, Actuarial Fairness Theory & Risk Theory may be used to anchor future studies on analyze the analysis of claim frequency and severity in auto insurance using generalized linear models in Philippines. From a practical perspective, insurers should increasingly adopt telematics and real-time driving data within their GLM frameworks. Policymakers should encourage and potentially mandate the integration of telematics data in auto insurance modeling.

Ferroelectric nematic fluids as spontaneous polarization field for enhanced orientational-dependent second-harmonic generation

ABSTRACT Second-order nonlinear optical effects have piqued researchers’ interest in fundamental physics and practical perspectives. The ferroelectric nematic liquid crystals (NF LCs) have recently drawn attention to LC nonlinear optical applications due to their relatively high second-harmonic generation output. Further improving the nonlinear optical properties to get closer to the performance of inorganic nonlinear optical materials is challenging. Here, we take a blending strategy to enhance the nonlinear optical response of a prototype NF LC, DIO. We mixed an organic nonlinear optical crystalline material, 3,5,5-trimethyl (cyclohex-2-enylidene) malononitrile (TCM), with DIO and investigated the effects of TCM doping at various concentrations. We quantitatively determined the second-harmonic generation and spontaneous polarization as functions of temperature and concentration. We found that, compared with the pure DIO, the second-harmonic generation performance increased by about 130% at maximum, 93% in maximum for the nonlinear optical coefficient, and 10% in maximum for spontaneous polarization.

Reconceptualizing open schooling: towards a multidimensional model of school openness

ABSTRACT ‘Open schooling’ has become in recent years a burgeoning theme in the discourse on how to rethink education for the 21st century. This paper addresses a gap between calls for implementing an open schooling approach in policy papers and international reports and the scarcity of rigorous academic discourse on what open schooling theoretically means and practically entails in terms of school organization and curriculum. To this end, the paper presents an ecological model of school openness that is composed of eight interrelated dimensions: shared governance, ‘open’ curriculum, inner-school communities, learning communities, student participation, social engagement, parental involvement, and community collaborations. These dimensions are organized into three categories, accounting for organizational, pedagogical and communal aspects of school openness. The multidimensional nature of the model presented here provides a more intricate and nuanced account of open schooling that acknowledges the complexities and challenges that the movement towards greater openness yields for school communities. From an educational research perspective, this model functions to inform the understanding and examination of the multidimensionality of opening schools to their community. From an educational practice perspective, it can instigate in-depth and meaningful dialogue within school teams on what open schooling is and its ensuing merits.

Ultrasound Imaging in Knee Osteoarthritis: Current Role, Recent Advancements, and Future Perspectives.

While conventional radiography and MRI have a well-established role in the assessment of patients with knee osteoarthritis, ultrasound is considered a complementary and additional tool. Moreover, the actual usefulness of ultrasound is still a matter of debate in knee osteoarthritis assessment. Despite that, ultrasound offers several advantages and interesting aspects for both current clinical practice and future perspectives. Ultrasound is potentially a helpful tool in the detection of anomalies such as cartilage degradation, osteophytes, and synovitis in cases of knee osteoarthritis. Furthermore, local diagnostic and minimally invasive therapeutic operations pertaining to knee osteoarthritis can be safely guided by real-time ultrasound imaging. We are constantly observing a growing knowledge and awareness among radiologists and other physicians, concerning ultrasound imaging. Ultrasound studies can be extremely useful to track the response to various therapies. For this specific aim, tele-ultrasonography may constitute an easy tool aiding precise and repeated follow-up controls. Moreover, raw radio-frequency data from US backscattering signals contain more information than B-mode imaging. This paves the way for quantitative in-depth analyses of cartilage, bone, and other articular structures. Overall, ultrasound technologies and their rapid evolution have the potential to make a difference at both the research and clinical levels. This narrative review article describes the potential of such technologies and their possible future implications.

Navigating Sustainability A Bibliometric Analysis Of Carbon Management Accounting

In the era of increasing concerns over climate change and sustainable development, Carbon Management Accounting (CMA) research gains paramount attention. Previous studies focused on specific aspects of carbon accounting, leaving a gap in comprehensive exploration of CMA's holistic approach to sustainability challenges. This study aims to provide a comprehensive overview of the current state of CMA research and its implications for sustainability efforts. Bibliometric and network analyses, utilizing Harzing's Publish or Perish (PoP) and VOSviewer (VOS) software, 200 Scopus-indexed documents from 2013 to 2022 were examined. Performance analysis, citation analysis, journal analysis, and network analysis were employed to examine the field from research practice and system perspectives. From a practice-perspective, the analysis reveals CMA research as an "advancement," depicting progressive, impactful, and dynamism within the field. The system-perspective displays a “transformative” role characterized by prominence, synergy, and integration. Popular themes among researchers and countries include keywords like "carbon," "carbon accounting," "environmental policy," and "climate change." A significant gap between sustainability development and the carbon accounting model in CMA is identified, emphasizing the need for further integrated research. This study is pivotal for practitioners, policymakers, and researchers, aiding sustainability efforts and addressing global climate change.

Influence of AM Generated Burner Surface Roughness on NOx Emissions and Operability of Hydrogen-Rich Fuels

ABSTRACT The additive manufacturing (AM) technique enables the fabrication of advanced burner components to enhance the hydrogen capability of the existing gas turbines (GTs) and reduce the carbon footprints of the power generation sector. This technique produces rough surfaces that may require post-processing to maintain the desired functionality of a burner, particularly for hydrogen fuel with unique thermo-physical properties. This study, therefore, compared the stability of three swirlers of variable surface roughness manufactured using AM and traditional machining methods, with one of the AM swirler post-processed by grit-blasting. The comparison included a conventional benchmark (100% CH4), low carbon (23%volCH4/77%volH2) and zero carbon (100% H2) fuels across a range of equivalence ratios. Additionally, the study quantified the flame topology and emissions performance of the fuel blends for each swirler using high-speed OH* chemiluminescence and exhaust gas emissions measurements, respectively. The experimental investigation concluded that the AM-generated surface roughness within the considered range does not detrimentally impact NOX emissions and the stability of the fuel mix. However, the flame location was observed to be influenced by surface roughness and shifted more toward the vertical centerline of the burner with increased roughness. From the practical perspective, the results showed that post-manufacturing surface finishing offers negligible performance advantages, indicating potential cost reductions. It is recommended that further studies should investigate the influence of increased surface roughness on burner performance, as well as numerical modeling techniques which could provide an insight into when AM surfaces are likely to be more influential.

Children’s understanding of referential nominal metaphors: a path to the heart of text comprehension

ABSTRACT A referential metaphor is a cohesive tie between lexical items that are metaphorically related, (e.g. “The seagull took the bread from the coffee table. No one heard the thief”). The reference from the thief back to the seagull is metaphorical because thieves are human. The present article presents arguments and some empirical evidence that resolution of referential metaphors shares several of the core processes of general text comprehension. Two studies are reported. The first study found that resolution of referential metaphors is closely correlated to text comprehension and that ability to resolve referential metaphors contributes unique variance to reading comprehension over and above resolution of literal references. The goal of the second study was to explore in depth the inferential processes involved in the resolution of referential metaphors. This second study assessed the relative contributions of text-based (“bridging”) and knowledge-based inferences to the resolution of referential metaphors. The results support the assumption that resolution of referential metaphors requires a combination of these two types of inferential processes in addition to other components that are shared with text comprehension. Together, the two studies indicate the processing of referential metaphors shares inferential processes with general reading comprehension and thus open new theoretical and practical perspectives.

Synergies between the circular economy and carbon emission reduction

Climate change and sustainable development drive transformation in economic development models. Carbon emission reduction and the circular economy propel climate change and sustainable development, yet it's unclear if they synergize or counteract each other. This study examines the question from theoretical and practical perspectives. Using a theory-practice framework, bibliometric and big data analyses were conducted on the Web of Science and Chinese case data, totaling 2.29GB, to explore synergies between carbon emission reduction and the circular economy. The study finds predominantly synergistic interactions between the circular economy and carbon emission reduction, with minimal offsetting effects. That is, the circular economy markedly enhances carbon emissions reduction. At the theoretical level, the two fields are gradually evolving towards in-depth research, while at the practical level, collaboration is coalescing around four areas: hot fields, potential fields, auxiliary fields and common goals. A noteworthy contribution of this study is the development of a framework that synergizes theory and practice, providing a structured approach for future research in this domain. By quantifying the synergistic and offsetting relationship between the circular economy and carbon emissions reduction through systematic big data analysis, this research offers insights essential for achieving the UN's Sustainable Development Goals. We also stress the need for diverse case studies and multi-dimensional analyses in ongoing research.

Optimization of Glass-Powder-Reinforced Recycled High-Density Polyethylene (rHDPE) Filament for Additive Manufacturing: Transforming Bottle Caps into Sound-Absorbing Material.

Additive manufacturing presents promising potential as a sustainable processing technology, notably through integrating post-consumer recycled polymers into production. This study investigated the recycling of high-density polyethylene (rHDPE) into 3D printing filament, achieved by the following optimal extrusion parameters: 180 °C temperature, 7 rpm speed, and 10% glass powder addition. The properties of the developed rHDPE filament were compared with those of commonly used FDM filaments such as acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA) to benchmark the performance of rHDPE against well-established materials in the 3D printing industry, providing a practical perspective for potential users. The resulting filament boasted an average tensile strength of 25.52 MPa, slightly exceeding ABS (25.41 MPa) and comparable to PLA (28.55 MPa). Despite diameter fluctuations, the filament proved usable in 3D printing. Mechanical tests compared the rHPDE filament 3D printed objects with ABS and PLA, showing lower strength but exceptional ductility and flexibility, along with superior sound absorption. A life cycle analysis underscored the sustainability advantages of rHDPE, reducing environmental impact compared to conventional disposal methods. While rHDPE falls behind in mechanical strength against virgin filaments, its unique attributes and sustainability position it as a valuable option for 3D printing, showcasing recycled materials' potential in sustainable innovation.

Comparative transcriptomic and metabolomic analyses provide insights into the responses to high temperature stress in Alfalfa (Medicago sativa L.)

High temperature stress is one of the most severe forms of abiotic stress in alfalfa. With the intensification of climate change, the frequency of high temperature stress will further increase in the future, which will bring challenges to the growth and development of alfalfa. Therefore, untargeted metabolomic and RNA-Seq profiling were implemented to unravel the possible alteration in alfalfa seedlings subjected to different temperature stress (25 ℃, 30 ℃, 35 ℃, 40 ℃) in this study. Results revealed that High temperature stress significantly altered some pivotal transcripts and metabolites. The number of differentially expressed genes (DEGs) markedly up and down-regulated was 1876 and 1524 in T30_vs_CK, 2, 815 and 2667 in T35_vs_CK, and 2115 and 2, 226 in T40_vs_CK, respectively. The number for significantly up-regulated and down-regulated differential metabolites was 173 and 73 in T30_vs_CK, 188 and 57 in T35_vs_CK, and 220 and 66 in T40_vs_CK, respectively. It is worth noting that metabolomics and transcriptomics co-analysis characterized enriched in plant hormone signal transduction (ko04705), glyoxylate and dicarboxylate metabolism (ko00630), from which some differentially expressed genes and differential metabolites participated. In particular, the content of hormone changed significantly under T40 stress, suggesting that maintaining normal hormone synthesis and metabolism may be an important way to improve the HTS tolerance of alfalfa. The qRT-PCR further showed that the expression pattern was similar to the expression abundance in the transcriptome. This study provides a practical and in-depth perspective from transcriptomics and metabolomics in investigating the effects conferred by temperature on plant growth and development, which provided the theoretical basis for breeding heat-resistant alfalfa.

Science of science: A multidisciplinary field studying science

Science and knowledge are studied by researchers across many disciplines, examining how they are developed, what their current boundaries are and how we can advance them. By integrating evidence across disparate disciplines, the holistic field of science of science can address these foundational questions. This field illustrates how science is shaped by many interconnected factors: the cognitive processes of scientists, the historical evolution of science, economic incentives, institutional influences, computational approaches, statistical, mathematical and instrumental foundations of scientific inference, scientometric measures, philosophical and ethical dimensions of scientific concepts, among other influences. Achieving a comprehensive overview of a multifaceted field like the science of science requires pulling together evidence from the many sub-fields studying science across the natural and social sciences and humanities. This enables developing an interdisciplinary perspective of scientific practice, a more holistic understanding of scientific processes and outcomes, and more nuanced perspectives to how scientific research is conducted, influenced and evolves. It enables leveraging the strengths of various disciplines to create a holistic view of the foundations of science. Different researchers study science from their own disciplinary perspective and use their own methods, and there is a large divide between quantitative and qualitative researchers as they commonly do not read or cite research using other methodological approaches. A broader, synthesizing paper employing a qualitative approach can however help provide a bridge between disciplines by pulling together aspects of science (economic, scientometric, psychological, philosophical etc.). Such an approach enables identifying, across the range of fields, the powerful role of our scientific methods and instruments in shaping most aspects of our knowledge and science, whereas economic, social and historical influences help shape what knowledge we pursue. A unifying theory is then outlined for science of science – the new-methods-drive-science theory.

Solvation-Property Relationship of Lithium-Sulfur Battery Electrolytes Probed via Potentiometric Measurements

The Li-S battery is a promising next-generation battery chemistry that offers high energy density and low cost. Li-S battery has a unique chemistry with intermediate sulfur species readily solvated in electrolytes, and understanding their implications is important from both practical and fundamental perspectives. However, the nature of the solvated sulfur species, their interactions and their impact on the battery remains elusive, in part due to the paucity of techniques. Recently, our group developed a potentiometric technique to probe the solvation free energy of electrolytes. In this study, we utilize the technique to formulate solvation-property relationships in various electrolytes and investigate its impact on the solvated lithium polysulides (LiPS). We find that solvation free energy impacts Li-S battery voltage profile, LiPS solubility, Li-S battery cyclability and the Li metal anode, which are all critical to the battery's performance. Weaker solvation leads to a lower 1st plateau voltage, higher 2nd plateau voltage, lower LiPS solubility, and superior cyclability of Li-S full cell and Li metal anode. We explore the mechanisms behind these observed phenomena and discuss the implications for the design of high-performance electrolytes for Li-S batteries.

DiSSCover the Potential of FAIR Digital Object Annotations and How You Can Use Them!

The infrastructure for the Distributed System of Scientific Collections (DiSSCo) is in full development. Work within the DiSSCo Transition Project has been focused on building infrastructure, creating data models, and setting up Application Programming Interfaces (APIs) (Koureas et al. 2024). In the past years, DiSSCo has presented this work at different Biodiversity Information Standards (TDWG) conferences (Leeflang and Addink 2023, Leeflang et al. 2022, Addink et al. 2021). In this year’s session, we would like to focus on the human-facing application: DiSSCover. DiSSCover is the graphical user interface through which users can interact with Findable, Accessible, Interoperable and Reusable (FAIR) Digital Objects (FDOs), facilitating the curation and enhancement of specimen data (Islam 2024). Development started in 2022 and is ongoing. The interface acts as a gateway into the DiSSCo infrastructure, providing access to digital specimens and media. Extracted from the core DiSSCo API, the data is converted into an easily readable format and made discoverable through a diverse set of filters. DiSSCover’s main focus is to allow users to make annotations upon the data. Through the concept of annotations, we connect expert and machine-generated information, to create extended digital specimens (Hardisty et al. 2022), e.g, by creating linkages to other infrastructures, correcting or adding new information, or by triggering machine annotation services. Machine annotation services are automated scalable tools that run in the background and automatically curate and extend the specimen (Addink et al. 2023). Human users will remain important, as all annotations made by machine annotation services can be reviewed by a trusted person. Annotations are Fair Digital Objects and target a specific part of a specimen, be it a data fragment or an associated media file. At the heart of DiSSCover lies the Open Digital Specimen data specification (Leeflang and Addink 2023). It tries to harmonise multiple data standards into one generic specification based on the new Global Biodiversity Information Facility (GBIF) Unified Model (Robertson et al. 2022). The data is stored as JavaScript Object Notation (JSON) based on JSON Schemas (Anonymous 2024). Annotations are linked to specific data attributes using a JSON-path as the identifier. Data attributes can be individual terms, collections of terms called classes, or the whole object. This creates a flexible but complex data structure, the basis for which we used the World Wide Web Consortium (W3C) web annotation data model (Sanderson et al. 2017). The W3C Web annotation data model contains two main components: the target and body. The target specifies which data attribute the annotation is made on, for example, the term: ‘ods:specimenName’. This is a local term within the open Digital Specimen namespace (ods), which holds the accepted name of the digital specimen. The annotation body holds the value(s) that are appended to the digital specimen, and differ based upon the annotation motivation. DiSSCo recognises five different annotation motivations: addition, modification, comment, assessment and deletion, each of which has its own unique function. This creates a flexible structure that should be able to handle any information the user wants to add to the object. The challenge of DiSSCover is to preserve the complex structure of annotations, whilst making it convenient for users to work with. The session will provide a look at the different kinds of annotations and their use from a practical perspective. A demonstration of DiSSCover will show how users can create annotations, providing knowledge about the process that will give shape to DiSSCo’s main goal of enriching natural history data.

Development and factor structure of the teaching approach scale

IntroductionThe study presents the development and validation of the Teaching Approach Scale (TAS), a tool aimed at assessing teaching approaches in educational settings. Literature emphasizes the significance of collaboration and a student-centered approach in enhancing learning environments. However, the translation of these approaches into daily practices faces challenges due to entrenched traditions and individual perspectives. The TAS addresses this gap by assessing educators’ perspectives on teaching approaches.MethodExploratory and confirmatory factor analyses carried on a sample of 642 teachers revealed four dimensions defining learning approaches: (a) Development of students’ autonomy, (b) Comparison and synergy in the teacher’s group, (c) Development of the student as a person, and (d) Standardization of teaching.Results and discussionThe TAS serves as a valuable instrument for capturing teachers’ perspectives on teaching, thereby offering valuable insights for enhancing teaching practices and fostering professional development. Further studies need to face TAS validity and reliability, nevertheless, this study underscores the importance of considering teacher learning cultures in improving educational procedures, highlighting the role of individual perspectives in shaping teaching practices and learning environments.

Exploring the need and potential of ambulatory pharmacy practice for empowering patient and care delivery in India.

In recent years, rapidly changing disease profile patterns, shortage & uneven utilization of healthcare professionals contributed massive burden on the Indian healthcare system, which resulted in varying, fragmented, inconsistent healthcare delivery to the patients and poor patient management. Patients often face and experience many challenges like lack of accessibility, poor patient-healthcare provider relationships, and inadequate quality of care, resulting in unnecessary economic burden in managing their health conditions. Thus Indian healthcare reform is essential in enhancing its capacity to fulfill patients' health needs that can be addressed by focusing on key sustainable strategies and initiatives meant for enhancing coordination of care, expanding services accessibility, redeveloping healthcare infrastructure, implementing workforce innovation and strong governance with the incorporation of core principles such as patient-centeredness, integrated care and collaborative care approaches. The clinical and ambulatory pharmacy practice are fragment of the healthcare delivery which delivers pharmaceutical care and fulfils the needs of patients across healthcare settings. This paper focuses on the present & future perspectives of ambulatory pharmacy practice in India and the factors to be considered for implementing it in patient care.

Care quality and safety in long-term aged care settings: A systematic review and narrative analysis of missed care measurements.

To critically evaluate missed care measurement approaches and their application in long-term aged care (LTAC) settings. Systematic review using Tawfik's guideline. PubMed, Scopus, Web of Science, CINAHL and ProQuest were searched. Supplemental searching was from reference lists of retrieved records, first authors' ORCID homepages and Google advanced search for grey literature. Search limitations were English language, published between 1 January 2001 and 31 December 2022. COVIDENCE was utilized for screening, data extraction and quality appraisal. JBI Critical Appraisal Tools and COSMIN Risk of Bias Tool were used for quality appraisal. Data were summarized and synthesized using narrative analysis. Twenty-four publications across 11 regions were included, with two principal methods of missed care measurement: modified standard scales and tailored specific approaches. They were applied inconsistently and generated diverse measurement outcomes. There were challenges even with the most commonly used tool, the BERNCA-NH, including absence of high-quality verification through comparative analysis against an established 'gold standard', reliance on self-administration, incomplete assessment of constructs and inadequate exploration of psychometric properties. Globally, there are deficiencies in the effectiveness and comprehensiveness of the instruments measuring missed care in LTAC settings. Further research on theoretical and practical perspectives is required. Findings highlighted a critical need to establish a standardized, validated approach to measure missed care in LTAC settings. This review calls for collaborative efforts by researchers, clinical staff and policymakers to develop and implement evidence-based practices as a way of safeguarding the well-being of older clients living in LTAC settings. Measurements of missed care in LTAC settings rely on adapting acute care tools. There is a critical gap in measuring missed care in LTAC settings. Developing a new tool could improve care quality and safety in LTAC settings globally. Adhered to PRISMA guideline. No patient or public contribution.
