Published: July 2024

AbstractDevelopment of biocomposites is becoming a necessity due to environmental concerns. Polylactide is a matrix of choice, regarding its bio‐sourced and compostable nature along with its mechanical properties. In this study, poly(L‐lactide)/flax biocomposites were produced using thermoplastic resin transfer molding (TP‐RTM) in one step process from the monomer, affording sustainable and fully compostable composite materials. The polymerization of L‐lactide (L‐LA) monomer was promoted by tin octoate, affording poly(L‐lactide) (PLLA) matrices displaying monomer conversions superior to 96% and mass‐average molar masses above 140,000 g/mol. Flax fibers were used as received without any functionalization which is usually conducted to prevent the hydroxyl groups to conduct side reactions. Mechanical testing revealed bending modulus of 9.3 GPa and bending strength of 177 MPa comparable to existing literature values for PLLA/flax composites produced by other techniques. Digital microscopy analysis provided insights into impregnation quality and void characterization within the composites. In addition, the durability of these biocomposites was also evaluated via accelerated aging tests.Highlights
PLLA/flax biocomposites were produced by TP‐RTM for the first time.
In situ polymerization of the PLLA matrix associated with non‐functionalized flax fabrics was conducted.
Bending properties were found in line with those of PLLA/flax composites produced by compression molding.
Aging tests under UV at 50°C of PLLA/flax biocomposites were conducted.

Published: July 2024

AbstractQuantum battery (QB) is an energy storage and extraction device conforming to the principles of quantum mechanics. In this study, the characteristics of QBs are considered for the Heisenberg spin chain models in the absence and presence of Dzyaloshinskii‐Moriya (DM) interaction. The results show that the DM interaction can enhance the ergotropy and power of QBs, which shows the collective charging can outperform parallel charging regarding QB's performance. Besides, it turns out that first‐order coherence is a crucial quantum resource during charging, while quantum steering between the cells is not conducive to the energy storage of QBs. The investigations offer insight into the properties of QBs with Heisenberg spin chain models with DM interaction and facilitate us to acquire the performance in the framework of realistic quantum batteries.

Published: July 2024

AbstractAimThis study aimed to summarize the frequency and the antimicrobial susceptibility profiles of the Salmonella serotypes identified from the specimens of companion animals, livestock, avian, wildlife and exotic species within Atlantic Canada.Materials and MethodsThe retrospective electronic laboratory data of microbiological analyses of a selected subset of samples from 03 January 2012 to 29 December 2021 submitted from various animal species were retrieved. The frequency of Salmonella serotypes identified, and their antimicrobial susceptibility results obtained using the disk diffusion or broth method were analysed. The test results were interpreted according to the Clinical and Laboratory Standards Institute standard. The Salmonella serotypes were identified by slide agglutination (Kauffman–White‐Le‐Minor Scheme) and/or the Whole Genome Sequencing for the Salmonella in silico Serovar Typing Resource–based identification.ResultsOf the cases included in this study, 4.6% (n = 154) had at least one Salmonella isolate, corresponding to 55 different serovars. Salmonella isolation was highest from exotic animal species (n = 40, 1.20%), followed by porcine (n = 26, 0.78%), and canine (n = 23, 0.69%). Salmonella subsp. enterica serovar Typhimurium was predominant among exotic mammals, porcine and caprine samples, whereas S. Enteritidis was mostly identified in bovine and canine samples. S. Typhimurium of porcine origin was frequently resistant (>70.0%) to ampicillin. In contrast, S. Typhimurium isolates from porcine and caprine samples were susceptible (>70.0%) to florfenicol. S. Oranienburg from equine samples was susceptible to chloramphenicol, but frequently resistant (>90.0%) to azithromycin. In avian samples, S. Copenhagen was susceptible (>90.0%) to florfenicol, whereas Muenchen was frequently resistant (>90.0%) to florfenicol. S. subsp. diarizonae serovar IIIb:61:k:1,5 of ovine origin was resistant (50.0% isolates) to sulfadimethoxine. No significant changes were observed in the antibiotic resistance profiles across the study years.ConclusionsThis report provides data for surveillance studies, distribution of Salmonella serotypes and their antimicrobial resistance among veterinary specimens of Atlantic Canada.
Vietnam: Why are there Only few Innovations in Vietnamese Startups and SMEs? An Analysis from an Entrepreneurship and Management Perspective
Authors: Truong Minh Chương 
Published: July 2024

AbstractEntrepreneurship and Innovation (E&I) is the theme of much interest in recent years. E&I is expected to develop economies, particularly, emerging economies such as Vietnam. Vietnamese government has made a lot of efforts and policies to develop E&I and achieved some good results, but, not as high as expected. The innovations in Vietnamese startups and SMEs are still limited. This chapter aims to explain the reasons for this fact. A review of data published by the World Bank, OECD, and GMI were collected to understand the whole picture of Vietnamese innovation. Then, two studies on Vietnamese startups and SMEs innovation were presented. Results of the studies show that Vietnamese startups with innovations just cover a small part of total startups, e.g., Vietnamese entrepreneurs are just a few among people starting businesses. The creativity is the main difference between the entrepreneurs and the others. Vietnamese entrepreneurs have a shortage of entrepreneurial and managerial competencies, hence, most SMEs do not follow entrepreneurial orientation to continuously make innovations. As such, their market competition, and development are also constrained. Some implications to overcome this innovation limitation are proposed.

AbstractEight Novel chalcones were synthesized and their structures were confirmed by different spectral tools. All the prepared compounds were subjected to SRB cytotoxic screening against several cancer cell lines. Compound 5c exerted the most promising effect against MCF7 and HEP2 cells with IC50 values of 9.5 and 12 µg/mL, respectively. Real-time PCR demonstrated the inhibitory effect of compound 5c on the expression level of Antigen kiel 67 (KI-67), Survivin, Interleukin-1beta (IL-1B), Interleukin-6 (IL-6), Cyclooxygenase-2 (COX-2) and Protein kinase B (AKT1) genes. Flow-cytometric analysis of the cell cycle indicated that compound 5c stopped the cell cycle at the G0/G1 and G2/M phases in MCF7 and HEP2 treated cells, respectively. ELISA assay showed that Caspase 8, Caspase 9, P53, BAX, and Glutathione (GSH) were extremely activated and Matrix metalloproteinase 2 (MMP2), Matrix metalloproteinase 9 (MMP9), BCL2, Malondialdehyde (MDA), and IL-6 were deactivated in 5c treated MCF7 and HEP2 cells. Wound healing revealed that chalcone 5c reduced the ability to close the scrape wound and decreased the number of migrating MCF7 and HEP2 cells compared to the untreated cells after 48 h. Theoretical molecular modeling against P53 cancer mutant Y220C and Bcl2 showed binding energies of -22.8 and -24.2 Kcal/mole, respectively, which confirmed our ELISA results.

AbstractThe study examines the impact of integrated biofloc technology (BFT), different salinity levels, and their combined effects over 90 days on various physiological parameters. The investigation includes growth performance and feed utilization, water quality, the chemical composition of biofloc and fish, digestive enzymes, reproductive performance, stress and biochemical indicators, and antioxidant-immune responses in red tilapia (Oreochromis spp.) broodstock. The fish were initially weighed (males: n = 270; 104 ± 0.96 g; females: n = 270; 93.2 ± 0.66 g) and subsequently divided into 12 treatment groups (6 for males and 6 for females) spread across 36 separate tanks (3 tanks per treatment; 45 fish per treatment; 15 fish/tank). The treatments involved three salinity levels (18, 28, and 36 ppt) in both clear water (CW) and BFT systems. The outcomes demonstrated that fish in the 36 ppt salinity with BFT treatment demonstrated significant improvements (P < 0.05) in growth parameters (final body weight, weight gain, and specific growth rate, feed intake, and feed conversion ratio). The condition factor in BFT groups increased in all salinity situations. The survival rates of broodstock were consistently high in all experimental conditions The study found that BFT and salinity significantly impacted (P < 0.05) whole body contents (moisture, protein, lipid, and ash) in both males and females. Water quality parameters showed variations between BFT and CW, with notable impacts (P < 0.05) on dissolved oxygen and pH. The BFT and salinity influenced digestive enzyme activities (protease, amylase, and lipase) and reproductive performance (males) and the 36 ppt salinity with BFT recorded the highest values. The hemato-biochemical and antioxidant-immune responses were also impacted by BFT and salinity exposure. The study highlights the potential benefits of incorporating BFT into red tilapia aquaculture systems, particularly in optimizing growth, health, and reproductive performance under various salinity conditions, which can enhance sustainable intensification, disease control, and environmental stewardship.
Negative impacts of future forest succession on three threatened butterfly species
Authors: Sunde Johanna , Askling John , Kindvall Oskar , Johansson Victor , Franzén Markus 
Published: July 2024

AbstractThe dynamic interplay between anthropogenic activities and biodiversity conservation necessitates a nuanced understanding of habitat change, especially in contexts marked by transitions from grasslands to forested areas. This investigation utilised three threatened butterfly species—the Marsh Fritillary, Apollo, and Large Blue—as models to explore how grassland associated species respond to altered environmental conditions. The methodology encompassed extensive field surveys and statistical analyses with ecological niche modelling to determine their current and future distributions on the Island of Gotland. The species were surveyed under distinct years from 2017 to 2020 in a total of 3333 hectares in a 6000 hectare area—the Marsh Fritillary in 2017 (1232 hectares), Apollo in 2019 (2346 hectares), and Large Blue in 2020 (2256 hectares). Results revealed that the estimated current extents of suitable habitats were 49,104 hectares for the Marsh Fritillary (15.6% of the island), 45,646 hectares for Apollo (14.5%), and 33,089 hectares for Large Blue (10.5%). In general, increased forest and shrub cover and decreased heterogeneity negatively affected butterfly occupancy, but each species exhibited unique habitat preferences. The predictive modelling demonstrated that continued succession would reduce the amount of habitats predicted to be suitable and generated alarming forecasts—a twofold increase in forest and shrub cover suggests habitat declines of 41%, 47%, and 65% for the Marsh Fritillary, Apollo, and Large Blue, respectively. Given these findings, proactive measures are imperative for strategically managing these habitats to preserve landscape heterogeneity and accommodate diverse ecological needs. This study is important to conservation management providing, crucial insights amid anthropogenic and ecological changes.
Landrace in situ (on-farm) conservation: European Union achievements
Authors: Raggi Lorenzo , Spataro Giorgia , Negri Valeria 
Published: July 2024

AbstractThis paper offers an insight on present status of on-farm conservation of landrace diversity in the European Union. The review initially examines the types of materials that are the object of on-farm conservation, assesses the current status of maintenance and reproduction within farms and gardens, explores the motivations that drive ongoing conservation efforts as a foundation for future enhancement and identifies the key actors involved and their respective roles. Secondarily, it reviews European Union policies and their provisions supporting the conservation of crop diversity in the fields, with a particular focus on regulations pertaining to the commercialization of landrace seeds. Given that the availability of propagation material remains a primary constraint to the widespread dissemination of landraces, the review also includes current achievements and identifies constraints that could be mitigated. The discussion highlights how to continue and intensify the development and implementation of agro-environmental and seed policies as well as how further collection, documentation, study and promotion of the traditional farmers’ knowledge ̶ associated with the development, production and utilization of the traditional local products ̶ can improve the present situation. It is hoped that the model applied in the European Union could be also useful in other regions of the world.
Toward an Ethics of Ambiguity in Critical Work and Organizational Psychology: From ‘Blank’ to ‘Troubled’ Subjectivity
Authors: Dashtipour Parisa , Gerard Nathan , Rolo Duarte 
Published: July 2024

AbstractIn recent years, a scholarly movement has taken hold that is critical of work and organizational psychology (WOP). Referred to as critical work and organizational psychology (CWOP), this movement problematizes some of the foundational premises of WOP, including its lack of reflexivity on its own values and ethics. While bringing increased attention to reflexivity and ethics as vital to critical theorizing and praxis, CWOP has yet to concertedly engage with ethics. This conceptual paper has two aims. The first is to outline existing ethical approaches in CWOP. Reviewing the literature, we suggest there are currently three tentative critical–ethical positions: (1) a critique of mainstream WOP for its ethical failures, (2) espousal of a radical humanist ethics, and (3) an ethics of ambiguity. The latter is embedded in CWOP literature, but not yet articulated as such. Our second aim is therefore to make an ethics of ambiguity a recognized and explicitly embraced form of ethics that is rooted in a sustained engagement with the conceptualization of subjectivity as such. To clarify the risks inherent to theorizing ethics without a sufficiently robust understanding of subjectivity, we juxtapose ‘blank subjectivity’ with ‘troubled subjectivity,’ two notions informed by psychoanalysis and psychosocial studies. We argue that a theory of subjectivity as troubled is at the heart of an ethics of ambiguity. The paper concludes by discussing the contribution of an ethics of ambiguity to CWOP, while also pointing to some convergences between the different critical–ethical positions.

Abstract
Purpose
To evaluate the ventricular electrophysiologic effects of long-term stimulation of the left dorsal branch of thoracic nerve (LDTN) derived from the left stellate ganglion (LSG) in a canine model of chronic myocardial infarction (MI).

Methods
Seventeen adult male beagles were randomly divided into three groups: the sham group (sham operated, n = 6), the MI group (n = 6), and the MI + LDTN group (MI plus LDTN stimulation, n = 5). The canine model of chronic MI was induced by the occlusion of the left anterior descending artery (LADO). The LDTN was separated and intermittently stimulated immediately after LADO for 2 months. The heart rate variability (HRV) analysis, in vivo electrophysiology, the evaluation of LSG function and neural activity, histological staining, and western blotting (WB) assay were performed to evaluate the effect of LDTN stimulation on the heart.

Results
The canine MI model was successfully established by LADO, and the LDTN was separated and stimulated immediately after LADO. The HRV analysis showed that LDTN stimulation reversed the increased LF value and LF/HF ratio of the MI group. LDTN stimulation prolonged the shortening ERP and APD90, decreased the dispersion of ERP and APD90, and increased the VFT. Additionally, LDTN stimulation inhibits the LSG function and neural activity. Furthermore, LDTN stimulation suppressed the activation of Wnt/β-catenin signaling, which contributed to the LSG neuronal apoptosis by upregulation of pro-apoptotic Bax and downregulation of anti-apoptotic Bcl-2.

Conclusion
LDTN stimulation could attenuate cardiac sympathetic remodeling and improve ventricular electrical remodeling, which may be mediated by suppressing the activated Wnt/β-catenin signaling pathway and then promoting the LSG neuronal apoptosis.
Methodological Overlap in Early Childhood Education Self-Regulation Research: An Interdisciplinary Systematic Review
Authors: Ross Robbie A. , Ascetta Kate E. 
Published: July 2024

AbstractYoung children’s self-regulation (SR) skills are linked to many important outcomes across the lifespan and school stakeholders widely agree that these skills should be prioritized in schools. Despite broad agreement about the importance of these skills, the diverse field of SR research is rife with a lack of clarity in both conceptual definitions and measurement with many different terms and definitions used interchangeably. With a systematic review of early childhood SR research in schools, we aimed to add to these efforts by cataloguing which SR variables researchers measure and the specific methodological choices made to capture such variables. Coders identified 319 peer-reviewed articles published between 2010–2020 that included a school-based measurement of self-regulation related constructs among children between 3- and 8-years. This revealed 11 distinct variable terms used widely in the literature to refer to SR related skills or characteristics and behavior problems was overwhelmingly the most frequent. Studies of many of these variables relied heavily on adult reports, usually teachers, and the use of multiple informants to measure variables was uncommon. Findings further highlight the conceptual clutter in SR research, point to possible points of empirical weaknesses in the measurement of these skills, and identify some methodological overlap in how variables are being operationalized in the literature.
Stimming as Thinking: a Critical Reevaluation of Self-Stimulatory Behavior as an Epistemic Resource for Inclusive Education
Authors: Tancredi Sofia , Abrahamson Dor 
Published: July 2024

AbstractPeripheral sensorimotor stimming activity, such as rocking and fidgeting, is widely considered irrelevant to and even distracting from learning. In this critical-pedagogy conceptual paper, we argue that stimming is an intrinsic part of adaptive functioning, interaction, and cognitive dynamics. We submit that when cultural resources build from students’ own sensorimotor dynamics, rather than subjugating them to hegemonic corporeal norms, learners’ intrinsic sensorimotor behaviors may be embraced and empowered as mental activity. This call for transformative inclusive pedagogy is of particular importance for neurodivergent children whose sensorimotor engagements have historically been ostracized as disruptive. Following a conceptual analysis of stimming that builds on a range of neuro-cognitive empirical studies drawing on post-cognitivist embodied cognition theory, we imagine inclusive educational futures that disrupt sedentary instructional design to elevate minoritized learners’ sensorimotor activity. As proof of concept, we present an example inclusive embodied activity, balance board math, a pedagogical tool designed to elicit stimming as thinking. We propose a set of design heuristics for realizing stimming’s pedagogical potential.
Calling “Gevald”: on the emergence of negative election forecasts in partisan communications
Authors: Yechiam Eldad , Zeif Dana 
Published: July 2024

AbstractIndividuals were found to anonymously predict positive election outcomes for their preferred candidate. Yet, there is little scientific knowledge about election predictions made in the context of same-camp political communications (i.e., partisan communications) that are presumably meant to encourage other supporters. In five studies of low-information elections and a study of hypothetical U.S. elections (n = 1889), we found that people tended to communicate favorable forecasts to others sharing their view, compared to the neutral point and to the actual election outcomes. On the other hand, negative framing reduced the positivity of forecasts in these communications to the extent that it led most participants to predict an election loss. This occurred in response to a single addressee acting discordantly and even more strongly when the election results were phrased as a drop. When both positive and negative framing options were available, this still negativity affected participants’ predictions even though only a minority selected the negative framing option. Thus, people tend to make optimistic election predictions in partisan communications, but this pattern is easily manipulable given subtle changes in the forecasting prompt, either by negative framing or selectable positive and negative framing.
