The Temporal Structuring of Corporate Sustainability
Authors: Mena Sébastien , Parker Simon 
Published: April 2024

AbstractResearch on corporate sustainability has started to acknowledge the role of temporality in creating more sustainable organizations. Yet, these advances tend to treat firms as monolithic and we have little understanding of how different temporal patterns throughout an organization shape perceptions of and actions toward sustainability. Building on studies highlighting how the temporal structures of work shape employee engagement with different organizational processes and issues, we seek to answer: How does the temporality of work practices structure perceptions of corporate sustainability throughout the firm? Using data from an ethnography of a small European sustainable bank, we provide an account of the variety of ways in which employees in different departments perceive the bank and how they engage with sustainability. We then go on to show how the temporal structures of work practices within different departments help explain some divergence in perceptions of sustainability. Our study highlights the variegation of temporal structures in organizational processes of meaning-making and its role for a better understanding of the efforts to make corporations more sustainable.

Published: April 2024

AbstractWater scarcity is a problem that faces many regions. In a developing and arid countries, the need for fresh water is exponentially increasing. One of the most water consuming industries is the construction industry, especially in concrete manufacturing. This research is an evaluation of the Reliability of recycled wastewater to be used in concrete manufacturing. Two different wastewater treatment regimens are implemented: secondary and tertiary treated wastewater. The treated wastewater, either secondary or tertiary, replaces potable water with percentages of 25%, 50%, and 100%. The mixture of the two types of water is used in concrete mixing and curing. Control specimens with pure potable water are cast for the comparison. The experimental program investigated the cement setting, and for fresh concrete slump test is performed on all concrete mixtures. The hardened concrete is tested in compression and flexural strengths at ages of 7 days, 28 days, and 90 days. To investigate concrete durability, permeability test is conducted in addition to sulfate attack resistance. The concrete chemical composition is compared using the X-Ray Defragmentation (XRD) test. The results show that the treated wastewater may delay both the initial and final setting. The phenomenon is more pronounced in secondary treated wastewater. No significant effect on concrete performance in the fresh state is detected. For the compressive strength, both treatment regimens can be safely used. However, the flexural strength is reduced at the late ages. Using treated wastewater affects the permeability of concrete to be more durable and protect the reinforcement steel from rusting. For the XRD test, the results show different intensities and positions of the peaks of the different compounds encountered in the treated wastewater. Under sulfate attach, the treated wastewater specimens give higher expansion compared with potable water. In conclusion secondary and tertiary treated wastewater can be used in concrete mixing and curing. However, the manufactured concrete should be protected from sulfate attack to avoid excessive expansion.

AbstractOne of the most critical pillars of Industry 4.0 (I4.0) is Additive Manufacturing (AM) or 3D Printing technology. This transformative technology has garnered substantial attention due to its capacity to streamline processes, save time, and enhance product quality. Simultaneously, environmental concerns are mounting, with the growing accumulation of plastic bottle waste, offering a potential source of recycled material for 3D printing. To thoroughly harness the potential of AM and address the challenge of plastic bottle waste, a robust supply chain network is essential. Such a network not only facilitates the reintegration of plastic bottle waste and 3D printing byproducts into the value chain but also delivers significant environmental, social, and economic benefits, aligning with the tenets of sustainable development and circular economy. To tackle this complex challenge, a Mixed-Integer Linear Programming (MILP) mathematical model is offered to configure a Closed-Loop Supply Chain (CLSC) network with a strong emphasis on circularity. Environmental considerations are integral, and the primary objective is to minimize the overall cost of the network. Three well-known metaheuristics of Simulated Annealing (SA), Genetic Algorithm (GA), and Particle Swarm Optimization (PSO) are employed to treat the problem which are also efficiently adjusted by the Taguchi design technique. The efficacy of our solution methods is appraised across various problem instances. The findings reveal that the developed model, in conjunction with the fine-tuned metaheuristics, successfully optimizes the configuration of the desired circular CLSC network. In conclusion, this research represents a significant step toward the establishment of a circular supply chain that combines the strengths of 3D printing technology and the repurposing of plastic bottle waste. This innovative approach holds promise for not only reducing waste and enhancing sustainability but also fostering economic and social well-being.

Published: April 2024

AbstractAir pollution is the one of the most significant environmental risks to health worldwide. An accurate assessment of population exposure would require a continuous distribution of measuring ground-stations, which is not feasible. Therefore, significant efforts are spent in implementing air-quality models. However, a complex scenario emerges, with the spread of many different solutions, and a consequent struggle in comparison, evaluation and replication, hindering the definition of the state-of-art. Accordingly, aim of this scoping review was to analyze the latest scientific research on air-quality modelling, focusing on particulate matter, identifying the most widespread solutions and trying to compare them. The review was mainly focused, but not limited to, machine learning applications. An initial set of 940 results published in 2022 were returned by search engines, 142 of which resulted significant and were analyzed. Three main modelling scopes were identified: correlation analysis, interpolation and forecast. Most of the studies were relevant to east and south-east Asia. The majority of models were multivariate, including (besides ground stations) meteorological information, satellite data, land use and/or topography, and more. 232 different algorithms were tested across studies (either as single-blocks or within ensemble architectures), of which only 60 were tested more than once. A performance comparison showed stronger evidence towards the use of Random Forest modelling, in particular when included in ensemble architectures. However, it must be noticed that results varied significantly according to the experimental set-up, indicating that no overall best solution can be identified, and a case-specific assessment is necessary.
Tendency, Repetition, and the Activity of the Mind in Traumatic Experiences
Authors: Ingerslev Line Ryberg 
Published: April 2024

AbstractThe study of traumatic experiences led Freud to investigate what he termed a compulsion to repeat. The present paper takes up the idea of a tendency to repeat something that reinforces psychic pain and asks which kind of agency is possible in the light of traumatic repetitions. First, the experiential roots of repetitive doings induced by trauma are investigated. Might a compulsion to repeat belong to the sphere of the kind of tendencies which Husserl terms “generally unconscious”? And if so, does this sphere bring us to the limit of phenomenology where we might need to cooperate with psychoanalysis to make sense of the manifestations of such an unconscious sphere? This is proposed in section two. In section three, Freud’s notion of the compulsion to repeat is discussed. At this point, the repetitive activity of the mind is investigated as the traumatized person’s ongoing struggle to survive with the trauma and as a struggle to understand what survival in this case even means. In section four, an attempt is made to describe the kind of agency involved in the repetitive activity of the mind. The paper concludes that weak agency is possible in traumatic repetition when understood as the person’s ongoing attempt to compose a future for what has been lost.

Published: April 2024

Abstract
Purpose
To detect and analyze the influence of the duration of tamponade with silicone oil on the foveal and parafoveal thickness in cases of rhegmatogenous retinal detachment.

Methods
This is a retrospective cohort study of 64 eyes with rhegmatogenous retinal detachment in one eye who underwent pars plana vitrectomy (PPV) with silicone oil injection during the period between January 2019 and December 2021. The patients were divided into 2 groups. Group A with early removal of the silicone oil after 3–4 months and Group B with late removal of the silicone oil (SOR) after 6–8 months. The 2 groups were compared as regards the central foveal (CFT) and parafoveal (PFT) thickness changes from baseline, just before SOR, and after SOR. Changes in best corrected visual acuity (BCVA), relative risk of severe thinning. It was conducted at Kasr Alainy Hospital.

Results
64 eyes were enrolled in the study. Group A included 36 eyes, and group B included 28 eyes. The mean CFT changed insignificantly from 253 ± 52 μm to 252 ± 48 μm after SOR in group A; while it changed significantly from 211 ± 52 μm to 202 ± 46 μm after SOR in group B. The mean PFT decreased insignificantly from 299 ± 39 μm to 297 ± 40 μm in group A, while it decreased significantly from 284 ± 46 μm to 273 ± 44 μm in group B. Lines of improvement of BCVA were 4.11 ± 1.88 in group A, and 2.00 ± 1.24 in group B. Relative risk of severe foveal thinning after SOR was 14.3, and severe parafoveal thinning was 15.43, in group B compared to group A.

Conclusion
Longer period of silicone oil tamponade may carry a higher risk for severe foveal and parafoveal thinning after silicone oil removal.

Trial registration
The study was registered at clinical trial.gov under the title of (Duration of silicone oil tamponade on foveal and parafoveal thickness in Rhegmatogenous Retinal Detachment) with an ID NCT05817630 at April 2023 “retrospectively registered”.
Clinician Opinions Regarding the Usefulness of the BOSA for ASD Assessment in a Service for Children Aged Under 12 Years
Authors: Shapter Sophie , Carroll Amy , Roberts Kate 
Published: April 2024

Abstract
The COVID-19 pandemic and the subsequent social distancing policies forced healthcare teams to drastically alter the way they deliver services. This was particularly challenging for clinicians involved in diagnosing autism spectrum disorder (ASD), as assessment tools and methods required face-to-face social interactions between clinicians and children. To address this, the Brief Observation of Symptoms of Autism (BOSA) was developed to ensure that people suspected of ASD can receive diagnostic assessments during the pandemic. This project aimed to explore clinicians’ opinions on the BOSA, particularly regarding the usefulness of the assessment for clinicians to clarify diagnostic outcomes of ASD assessments. Both quantitative and qualitative data was gathered within an NHS community paediatric team. This included a questionnaire for clinicians to complete, and data from the BOSA assessments done in the service. Thematic analysis and descriptive statistics revealed that many clinicians felt that the BOSA can be beneficial in certain cases, such as selective mutism, and found the BOSA particularly helpful for observing parent–child interactions. These findings highlighted important information that the Autism Diagnostic Observation Schedule Second Edition (ADOS-2) does not give opportunities to observe. Clinicians reported that at times, the BOSA materials, brevity and parental administration created barriers to gathering information for diagnostic decisions. As may be expected, clinicians showed a clear preference for the more familiar and validated ADOS-2. However, the study highlights perceived limitations of the ADOS-2 and strengths of the BOSA, with recommendations made for future practice and research.
The commercial potential of Aphanizomenon flos-aquae, a nitrogen-fixing edible cyanobacterium
Authors: Scoglio Gabriel D. , Jackson Harry O. , Purton Saul 
Published: April 2024

AbstractAphanizomenon flos-aquae (AFA) is a Gram-negative nitrogen-fixing freshwater filamentous cyanobacterium with a rich nutritional profile that is approved for human consumption by both the Food and Drug Administration and the European Food and Safety Authorities. It has a high protein content (60-70%) and contains numerous vitamins, minerals and trace elements together with several high-value compounds with nutraceutical properties, such as C-phycocyanin and β-phenylethylamine. 500-1000 t of AFA dry biomass are currently wild harvested from natural blooms that occur seasonally in Klamath Lake, Oregon, USA, and distributed as a nutritional supplement worldwide. The requirements and unreliability of wild harvesting, owing to the dependence of AFA growth on environmental conditions and potential contamination by microcystin toxins, threaten the availability of biomass supply and restricts commercial expansion. In this review we propose AFA cultivation in open ponds or closed photobioreactors to obtain a reliable production of unialgal biomass to resolve the supply issue and enhance AFA as a feedstock for specific high-value by-products. Furthermore, we explore potential strategies for maximising overall yield and seasonal robustness by using a synergistic combination of cultivation and wild harvesting. Controlled AFA cultivation would also facilitate the use of genetic manipulation to generate bespoke strains with improved commercial applications, such as increasing the cyanobacterium’s nitrogen-fixation rate to enhance its value as a biofertiliser. Ultimately, realising the untapped biotechnological potential of AFA requires a better understanding of its fundamental biology, robust methodologies for laboratory and large-scale cultivation, and the development of AFA-specific genetic engineering techniques.
Effect of dehydration method on the micro- and nanomorphological properties of bacterial cellulose produced by Medusomyces gisevii on different substrates

Published: April 2024

AbstractMany important properties of bacterial cellulose (BC), such as moisture absorption capacity, elasticity and tensile strength, largely depend on its structure. This paper presents a study on the effect of the drying method on BC films produced by Medusomyces gisevii using two different procedures: room temperature drying (RT, (24 ± 2 °C, humidity 65 ± 1%, dried until a constant weight was reached) and freeze-drying (FD, treated at − 75 °C for 48 h). BC was synthesized using one of two different carbon sources—either glucose or sucrose. Structural differences in the obtained BC films were evaluated using atomic force microscopy (AFM), scanning electron microscopy (SEM), and X-ray diffraction. Macroscopically, the RT samples appeared semi-transparent and smooth, whereas the FD group exhibited an opaque white color and sponge-like structure. SEM examination showed denser packing of fibrils in FD samples while RT-samples displayed smaller average fiber diameter, lower surface roughness and less porosity. AFM confirmed the SEM observations and showed that the FD material exhibited a more branched structure and a higher surface roughness. The samples cultivated in a glucose-containing nutrient medium, generally displayed a straight and ordered shape of fibrils compared to the sucrose-derived BC, characterized by a rougher and wavier structure. The BC films dried under different conditions showed distinctly different crystallinity degrees, whereas the carbon source in the culture medium was found to have a relatively small effect on the BC crystallinity.

Can General Practitioner Opioid Prescribing to Compensated Workers with Low Back Pain Be Detected Using Administrative Payments Data? An Exploratory Study
Authors: Vo Jennifer , Gray Shannon , Traeger Adrian C. , Di Donato Michael 
Published: April 2024

Abstract

Background
Approximately one third of Australians with accepted time loss workers’ compensation claims for low back pain (LBP) are dispensed opioid analgesics. Structured administrative payments data is scalable but does not directly link opioids to prescribers. We sought to determine whether opioid prescribing by general practitioners (GPs) to workers with workers’ compensation claims for LBP can be detected in structured administrative payments data.

Methods
We used a sample of workers with accepted time loss workers’ compensation claims for low back pain from 2011 to 2015 from the Australian states of Victoria and South Australia. We structured administrative data to test the assumption that opioid dispenses that occurred immediately after a GP encounter in sequence and occurred on the same date as the GP encounter are likely to be related. We measured the number and proportion of opioid dispenses with a GP encounter prior and the days between a GP encounter and opioid dispense.

Results
Nearly one third of workers (32.2%, N = 4,128) in our sample (n = 12,816) were dispensed opioids a median of five times (interquartile range 2, 17). There were 43,324 opioid dispenses to included workers. 30,263 (69.9%) of opioid dispenses were immediately preceded by a GP encounter. Of those dispenses, 51.0% (n = 15,443) occurred on the same day as the GP encounter.

Conclusion
At least one third of opioids dispensed to workers with claims for LBP can be potentially linked to GP prescribing using workers’ compensation structured administrative payments data. This approach could have potential applications in supporting monitoring and audit and feedback systems. Future research should test this approach with a more diverse array of pain medicines and medical practitioners.

Published: April 2024

AbstractAlthough several studies have analyzed the effects of spirituality on stroke survivors’ physical functioning and their caregiver’s outcomes, no systematic review or meta-synthesis was found to identify the lived experiences of stroke survivors and caregivers regarding spirituality. For these reasons, this study aimed to analyze quantitively and qualitatively research relating to stroke survivors’ and caregivers’ experiences. The included studies were RCT studies, quasi-experimental studies, qualitative, descriptive, ethnographic, and phenomenological studies, and cross-sectional studies (n = 37), with a total of 6850 stroke survivors and 1953 caregivers enrolled. Spirituality appears to play an important role in improving the quality of life and decreasing anxiety and depression of both stroke survivors and their caregivers.
Development and Application of a Domain-Specific TPACK Questionnaire—Findings from a Longitudinal Study on Teaching Human Biology Using Digital Tools
Authors: Mölgen Leona , Asshoff Roman , Heuckmann Benedikt 
Published: April 2024

AbstractThere are several specific digital tools now that have transformed the way science is taught. Correspondingly, teacher education programs have changed, and now they increasingly address the development of technology-related professional content knowledge (TPACK). Owing to the use of technology in specific domains of science teaching, there is an emergent need for domain-specific TPACK questionnaires. The present study investigates the development and application of a domain-specific TPACK questionnaire for teaching human biology using digital tools in a university-based teacher education program. A quasi-experimental between-subject design was applied for 13 weeks in the four study groups (n = 155). The intervention groups worked with digital tools in human biology, while the control groups participated without specific consideration of digital tools throughout the program. We succeeded in developing a questionnaire comprising seven reliable scales. The questionnaire development procedure described herein may be applicable to other science education disciplines. By the means of linear mixed modeling, we found that all students gained professional knowledge; however, treatment × time interactions revealed that belonging to the intervention group was the main driver of TPACK progression. Comparing the treatments, we found that at post-test, the intervention group reported higher levels of TPCK, TPK, and TCK, but not CK, PK, TK, and PCK. Sequential analyses of the longitudinal data highlighted that working with digital tools on a regular basis constitutes a TPACK boost effect. This study contributes to the literature on technology integration from the perspective of biology education, where specific tools that can be assessed using a domain-specific questionnaire are used.

Published: April 2024

AbstractFor nearly two decades, augmented reality (AR) has found diverse applications in education, particularly in science education, where its efficacy has been supported by relevant theories and many empirical studies. However, previous studies have revealed the following research deficit: While AR technology appears to influence learning-related variables, at the time of this study only few research on the use of AR glasses in physics, a discipline for which this technology seems particularly promising in the context of laboratory experiments, has been found. Thus, the present study uses an experimental comparison group design to investigate the question of how the use of AR glasses in a physics laboratory experiment (compared to in a learning setting without AR) influences students’ motivation to learn, their cognitive load during the learning process and their learning achievement. The study (sample size N = 75) investigated the impact of AR glasses in a physics laboratory experiment on optical polarization. Results align with prior research, indicating heightened motivation among learners using AR applications. However, the absence of a significant difference in cognitive load between AR and non-AR learners was unexpected. Despite expectations based on spatial contiguity, learners with AR showed no advantage in learning achievement, challenging existing meta-analyses in physics education. These findings suggest a need to shift focus from surface features, like specific AR technology, to the content design of AR applications. Future studies should analyze the deep structure of AR applications, identifying features conducive to learning.
