Scarcity of fixed carbon transfer in a model microbial phototroph-heterotroph interaction.

Although the green alga Chlamydomonas reinhardtii has long served as a reference organism, few studies have interrogated its role as a primary producer in microbial interactions. Here, we quantitatively investigated C. reinhardtii's capacity to support a heterotrophic microbe using the established coculture system with Mesorhizobium japonicum, a vitamin B12-producing α-proteobacterium. Using stable isotope probing and nanoscale secondary ion mass spectrometry (nanoSIMS), we tracked the flow of photosynthetic fixed carbon and consequent bacterial biomass synthesis under continuous and diurnal light with single-cell resolution. We found that more 13C fixed by the alga was taken up by bacterial cells under continuous light, invalidating the hypothesis that the alga's fermentative degradation of starch reserves during the night would boost M. japonicum heterotrophy. 15NH4 assimilation rates and changes in cell size revealed that M. japonicum cells reduced new biomass synthesis in coculture with the alga but continued to divide - a hallmark of nutrient limitation often referred to as reductive division. Despite this sign of starvation, the bacterium still synthesized vitamin B12 and supported the growth of a B12-dependent C. reinhardtii mutant. Finally, we showed that bacterial proliferation could be supported solely by the algal lysis that occurred in coculture, highlighting the role of necromass in carbon cycling. Collectively, these results reveal the scarcity of fixed carbon in this microbial trophic relationship (particularly under environmentally relevant light regimes), demonstrate B12 exchange even during bacterial starvation, and underscore the importance of quantitative approaches for assessing metabolic coupling in algal-bacterial interactions.

Digital leadership in the digital era of education: enhancing knowledge sharing and emotional intelligence

PurposeEstablishing an effective educational system is directly tied to academic leadership, a multifaceted concept that differs from one environment to another. The purpose of this research is to investigate the role of digital leadership (DL) aspects in the enhancement of technical knowledge sharing (KS) and dealing with emotional intelligence (EI) among the teaching faculty of higher education institutions (HEIs).Design/methodology/approachFollowing a quantitative and cross-sectional research design, convenient sampling is employed for data collection via a self-administered questionnaire from 320 faculty members of private HEIs in Pakistan.FindingsStructural equation model (SEM) is used for path analysis. The results reveal a positive and significant effect of DL, aspects like visionary leadership (VL), digital citizenship (DC), systematic improvement (SI), on knowledge sharing (KS), and emotional intelligence (EI).Practical implicationsThis study has highlighted the significance of DL in private HEIs. The findings of the study imply that institutional heads of higher education institutions (HEIs) can successfully manage the knowledge assets that they have and those of their staff members, ensure the successful adoption of technology and foster product and process innovation that improves organizational performance and integrates successful strategies into the educational system by demonstrating DL aspects. The research also analyzes institutional heads' present leadership strategies to enhance response to technological change and innovations, which are considered fundamental pillars of organizational success. Ultimately, this will extend the literature on adopting DL techniques towards digital transformation in the education system.Originality/valueThis study empirically confirms the role of DL aspects such as VL, DC, and SI towards KS and EI. Most of the research demonstrates the direct impact of DL on EI, whereas the aspects of DL are not directly related to KS and EI. Studies have also shown how DL enhances its role in incorporating leadership in organizations, industries, and education, mainly in Western countries.

Communication anxiety as barrier: extending theory of planned behavior on student intention to participate in synchronous online learning

Purpose Student in-class participation is a crucial aspect in the learning process, including in synchronous learning process. Several variables may hinder students from actively participating in synchronous learning including communication anxiety. As behavior, student in-class participation can be modeled using theory of planned behavior (TPB) with communication anxiety as barrier variable. The current study aims to investigate student decision-making process to actively participate in synchronous online learning using TPB frameworks and examine the effect of communication anxiety as part of extended TPB. Design/methodology/approach This was quantitative nonexperimental research conducted by gathering cross-sectional data through electronic survey. A total of 1,009 Indonesian college students voluntarily participate in the survey. Structural equation modeling was used to analyze the data and test the hypothesis. Findings The results indicate that there was significant and positive effect between TPB-related variables: (1) attitude, (2) subjective norms, (3) behavioral control, (4) intention and (5) behavior. Communication anxiety, as an additional variable in the extended model, shows significant and negative effects on behavioral control and active participation behavior. However, the communication anxiety indicates insignificant effect on students’ intention to participate in online synchronous learning. The findings support the evidence that students’ intention to actively participate in synchronous learning can be described using TPB and communication anxiety hinders student to actively participate in synchronous learning. Originality/value The paper extends TPB on student active participation. Prior research limited to original theory of planned behavior (TPB) on student in-class and massive open online course (MOOC) participations, whereas the current research includes communication anxiety as additional variable on extended TPB to understand students’ intention to actively participate in synchronous online learning.

It is critical to pay attention to their mental health status and determine which factors are positively associated with nursing staff mental health from the perspective of work-family. The purpose of this paper is to investigate the impact of perceived ambidextrous leadership on nurses’ mental health mediated by work-to-family enrichment and moderated by work climate for sharing family concerns.MethodsOne time-lagged study with three waves was conducted. A total of 358 questionnaires were distributed to registered nurses working at 10 hospitals in Guangzhou, China, and 265 valid questionnaires were returned. The quantitative approach to test hypotheses involves hierarchical regression analyses, the bootstrapping method and the simple slope test.ResultsThe research indicated that (a) perceived ambidextrous leadership had a positive influence on nurses’ work-to-family enrichment; (b) nurses’ work-to-family enrichment mediated the relationship between perceived ambidextrous leadership and nurses’ mental health; (c) work climate for sharing family concerns moderated the relationship between perceived ambidextrous leadership and nurses’ work-to-family enrichment.ConclusionNursing supervisors’ ambidextrous leadership interacted with work climate for sharing family concerns benefit the conservation of nurses’ personal resources, which in turn facilitates nurses’ work-to-family enrichment and improve their mental health.

A Grounded Theory of Walking for Health Promotion in Older Urban Adults.

Walking enhances the health, quality of life, and independence of older adults. However, a global decline in urban walking necessitates a reevaluation of segmented, quantitative approaches to policies and theoretical frameworks in geriatric medicine for promoting walking among older adults. This study conceptualized the perceptions, experiences, and behaviors regarding walking, from a health promotion perspective, among older urban adults. Pedestrian-friendly communities were explored for older adults in Seoul, South Korea, using a grounded theory. Thirty-eight older adults actively engaged in walking were recruited between July and December 2020. A qualitative multi-method approach was used, and the collected data were analyzed using open, axial, and selective coding, with axial coding integrating textual and spatiobehavioral information. The open-coding process yielded 92 concepts, 47 subcategories, and 19 categories. Using axial and selective coding principles, a conceptual framework was developed to explain how walking shaped the daily lives of older urban adults and provided multidimensional health benefits. Walking perception attributes were characterized by "embodied subjectivity as a healthy older adult," "autonomy of movement," and "walking as a way to enrich or sustain life." Active walking facilitated interactions between older adults and their neighborhood environment within the context of compact and accessible urban living. A healthy and age-friendly community encourages interactions between older adults and their neighborhood environment by providing opportunities for daily walking for several purposes, such as providing a sense of autonomy, increasing health-promoting behaviors, and creating a sense of community.

Quantitative assessment of reef foraminifera community from metabarcoding data.

Describing living community compositions is essential to monitor ecosystems in a rapidly changing world, but it is challenging to produce fast and accurate depiction of ecosystems due to methodological limitations. Morphological methods provide absolute abundances with limited throughput, whereas metabarcoding provides relative abundances of genes that may not correctly represent living communities from environmental DNA assessed with morphological methods. However, it has the potential to deliver fast descriptions of living communities provided that it is interpreted with validated species-specific calibrations and reference databases. Here, we developed a quantitative approach to retrieve from metabarcoding data the assemblages of living large benthic foraminifera (LBF), photosymbiotic calcifying protists, from Indonesian coral reefs that are under increasing anthropogenic pressure. To depict the diversity, we calculated taxon-specific correction factors to reduce biological biases by comparing surface area, biovolume and calcite volume, and the number of mitochondrial gene copies in seven common LBF species. To validate the approach, we compared calibrated datasets of morphological communities from mock samples with bulk reef sediment; both sample types were metabarcoded. The calibration of the data significantly improved the estimations of genus relative abundance, with a difference of ±5% on average, allowing for comparison of past morphological datasets with future molecular ones. Our results also highlight the application of our quantitative approach to support reef monitoring operations by capturing fine-scale processes, such as seasonal and pollution-driven dynamics, that require high-throughput sampling treatment.

Comparing 5D BIM costs: stilt housing against conventional housing for flood management

Purpose Sustainable and resilient infrastructure projects aim to reduce flooding impacts and improve community adaptability. For instance, flood-resistant stilts elevate structures, mitigating flood damage. Comprehensive consideration is crucial when adding elements to housing projects, incurring costs for all involved parties. This study aims to assess the viability of concrete stilts for cost-effective flood mitigation in Malaysian terrace housing. Design/methodology/approach The study evaluates cost implications through a comparative 5D building information modeling (BIM) cost analysis of stilted and conventional (standard) housing models. This assesses the percentage increase in total cost. Furthermore, a survey of construction professionals was undertaken. The study used online convenience and stratified sampling techniques. Out of the 222 emails that were sent, 27 construction professionals located in Johor, Sabah and Selangor within Malaysia participated in the research survey. Their perspectives on stilt housing prospects and factors for costing such structures were analyzed through a descriptive analysis using SPSS. Findings The case study models revealed that the incorporation of stilts could lead to a 21.64% increase in the overall cost per unit. This cost increase was primarily attributed to the additional reinforcement required. However, the survey findings highlighted that a majority of construction professionals perceived the cost increment to fall within the range of 10%–20%. Consequently, it becomes imperative to meticulously consider cost factors such as foundational requirements, staircases, and the extended construction duration to effectively curtail expenditures. The prospect of heightened costs potentially posing a threat to profit margins and discouraging developers necessitates careful financial management. Notwithstanding these challenges, the survey's insights underscored that professionals in the construction industry indeed recognize the potential of stilt technology in the realm of flood mitigation and management, particularly within housing projects. Practical implications This research has significant practical implications. It provides a precise financial contrast between housing categories using 5D BIM and incorporates construction experts’ viewpoints on raised housing. Enhanced design considerations for raised housing can make it economically viable, offering a cost-effective, nature-based approach to flood mitigation. This approach can bring substantial benefits to residents by reducing flood-related damages and enhancing community resilience. Originality/value One of the notable aspects of this research is its originality. It uses a dual quantitative methodology involving modeling and survey techniques to address its objectives effectively. This approach contributes significantly to the relatively limited body of research focused on stilt housing and the application of 5D BIM. By combining these methodologies, the study explores a relatively uncharted area, making a valuable contribution to the field.

To reveal the unseen low-hanging fruit: A multi-method study of Indonesian hospital pharmacist perception regarding the implementation of injection-to-oral conversion activity.

Previous studies have demonstrated that the adoption of injection-to-oral conversion strategies in hospitalised patient yields both clinical and economic benefits. The objective of this study was to provide a comprehensive description of the current state of implementation and evaluate the perspectives of hospital pharmacists to guide future initiatives towards conversion implementation in Indonesia. A multi-method design was utilised. Quantitative approach used cross-sectional study design in which data were collected online using Google Form from August to October 2021. Qualitative analysis employed a phenomenological approach by performing in-depth interviews from July to August 2021. Each approach's data were compared to discover connections and discrepancies, and the final interpretation was done simultaneously. A total of 204 pharmacists participated in the survey, with 64.2% of them reporting no previous experience in conversion. An in-depth interview included seven hospital pharmacists, with three themes were emerged: (1) strategic roles of the pharmacist; (2) key considerations; and (3) potential barriers and enablers of conversion implementation. Based on the elaboration of quantitative and qualitative data, the study found that pharmacist had strong perception regarding pharmacist role in conversion despite their little experience in implementing the activity. For future improvement, a platform that taking into account the pharmacist current conditions and insights should be created. Pharmacists appreciated conversion activity and grasped its concepts despite little clinical experience. Consider possible enabling and barrier factors and essential considerations before taking action. Local guidelines and instructional materials that emphasise application or implementation are encouraged. Furthermore, the implementation project must be piloted and evaluated for clinical and economic outcomes.

THE PERCEPTIONS OF STUDENTS REGARDING GENDER EQUALITY POLICIES IN UNIVERSITIES

The study is about the perceptions of students of the University of Korca regarding the university's commitment to gender equality. Albanian universities have made significant efforts in gender mainstreaming. As part of a higher education institution, we must offer new generations a different path, free from prejudice and stereotypes, embracing people’s freedom and appreciating their individuality and originality. There is a significant commitment from the University of Korca (UNIKO) toward gender equality policies. The paper aims to point out the perceptions of students on gender equality policies followed by UNIKO and the commitment of the university to build an honest and communicative learning and work environment where people are treated equally and there is no discrimination, as well as a community which conveys trust, a sense of belonging and shared goals. A quantitative approach was used for this study. A questionnaire was conducted to measure the perception of students on gender equality policies in the university. The students were recruited in the four faculties of UNIKO. The study focused on students' knowledge of gender mainstreaming; their participation in trainings and activities focused on gender issues; equal representation in the decision-making units and awareness of gender equality and unconscious gender biases. The study showed a high interest of students in the gender policies of the institution, but a more visible involvement of students in informative activities and greater awareness to address gender issues is suggested.

How teachers’ student voice practices affect student engagement and achievement: exploring choice, receptivity, and responsiveness to student voice as moderators

AbstractStrategies that promote student voice have long been championed as effective ways to enhance student engagement and learning; however, little quantitative research has studied the relationship between student voice practices (SVPs) and student outcomes at the classroom level. Drawing on survey data with 1,751 middle and high school students from one urban district, this study examined how the SVP of seeking students’ input and feedback related to their academic engagement, agency, attendance, and grades. Findings revealed strong associations between this SVP and student engagement. Additionally, results showed that having just one teacher who uses the SVP is associated with significantly greater agency, better math grades, higher grade point averages, and lower absent rates than having no teachers who do so. In models testing interaction effects with choice, responsiveness, and receptivity to student voice, teachers’ receptivity was strongly associated with all outcomes. Few interaction effects were found. This study contributes compelling evidence of the impact of classroom SVPs and teacher receptivity to student voice on desired student outcomes.
