AbstractBiopolymers that mimic the extracellular matrix are favourable in tissue engineering. However, the rapid degradation and the lack of mechanical and enzymatic stabilities of these biopolymers prompt researchers to composite different biopolymers. In this study, we aim to develop an acellular gelatin-chitosan-cellulose nanocrystal (GCCNC) scaffold as a potential wound dressing. The GCCNC mixture was homogenised via ultrasonication and the genipin crosslinking was performed by magnetic stirring. The mixture was then frozen at − 80 °C for 6 h and freeze-dried. The effects of different ratios of gelatin and chitosan with cellulose nanocrystals on the physiochemical properties, mechanical properties, and cellular biocompatibility were studied. Our results herein showed that G3C7CNC demonstrated a homogenous interconnected porous structure with a good porosity (67.37 ± 9.09%) and pore size (148.46 ± 48.68 µm), acceptable swelling ratio (1071.11 ± 140.26%), adequate water vapour transmission rate (315.59 ± 25.27 g/m2/day), low contact angle (70.21 ± 6.79°), and sufficient mechanical strength (modulus of 64.67 ± 12.42 MPa). The lower biodegradation rate in the G3C7CNC (0.06 ± 0.01 mg/hr) compared to G10CNC (0.48 ± 0.07 mg/hr) together with the absence of glass transition phenomenon indicated an increase in both enzymatic and thermal stabilities. Furthermore, G3C7CNC was non-cytotoxic and biocompatible with human epidermal keratinocytes (HEKs) and human dermal fibroblasts (HDFs). The presence of collagen type I and α-smooth muscle actin expression in HDFs, together with the expression of cytokeratin-14 in HEKs, demonstrated our scaffold’s ability to maintain normal skin physiological functions. Therefore, this study proposes that the fabricated GCCNC scaffold could serve as a potential acellular skin substitute in managing chronic wounds.
Making Sense of Generative Learning
Authors: Fiorella Logan 
Published: April 2023

AbstractHow do learners make sense of what they are learning? In this article, I present a new framework of sense-making based on research investigating the benefits and boundaries of generative learning activities (GLAs). The generative sense-making framework distinguishes among three primary sense-making modes—explaining, visualizing, and enacting—that each serve unique and complementary cognitive functions. Specifically, the framework assumes learners mentally organize and simulate the learning material (via the visualizing and enacting modes) to facilitate their ability to generalize the learning material (via the explaining mode). I present evidence from research on GLAs illustrating how visualizations and enactments (instructor-provided and/or learner-generated) can facilitate higher quality learner explanations and subsequent learning outcomes. I also discuss several barriers to sense-making that help explain when GLAs are not effective and describe possible ways to overcome these barriers by appropriately guiding and timing GLAs. Finally, I discuss implications of the generative sense-making framework for theory and practice and provide recommendations for future research.

AbstractData discovery, the ability to find datasets relevant to an analysis, increases scientific opportunity, improves rigour and accelerates activity. Rapid growth in the depth, breadth, quantity and availability of data provides unprecedented opportunities and challenges for data discovery. A potential tool for increasing the efficiency of data discovery, particularly across multiple datasets is data harmonisation.A set of 124 variables, identified as being of broad interest to neurodegeneration, were harmonised using the C-Surv data model. Harmonisation strategies used were simple calibration, algorithmic transformation and standardisation to the Z-distribution. Widely used data conventions, optimised for inclusiveness rather than aetiological precision, were used as harmonisation rules. The harmonisation scheme was applied to data from four diverse population cohorts.Of the 120 variables that were found in the datasets, correspondence between the harmonised data schema and cohort-specific data models was complete or close for 111 (93%). For the remainder, harmonisation was possible with a marginal a loss of granularity.Although harmonisation is not an exact science, sufficient comparability across datasets was achieved to enable data discovery with relatively little loss of informativeness. This provides a basis for further work extending harmonisation to a larger variable list, applying the harmonisation to further datasets, and incentivising the development of data discovery tools.
Tournament incentives affect perceived stress and hormonal stress responses
Authors: Dohmen Thomas , Rohde Ingrid M. T. , Stolp Tom 
Published: April 2023

AbstractWe conduct a laboratory experiment among male participants to investigate whether rewarding schemes that depend on work performance—in particular, tournament incentives—induce more stress than schemes that are independent of performance—fixed payment scheme. Stress is measured over the entire course of the experiment at both the hormonal and psychological level. Hormonal stress responses are captured by measuring salivary cortisol levels. Psychological stress responses are measured by self-reported feelings of stress and primary appraisals. We find that tournament incentives induce a stress response whereas a fixed payment does not induce stress. This stress response does not differ significantly across situations in which winners and losers of the tournament are publically announced and situations in which this information remains private. Biological and psychological stress measures are positively correlated, i.e. increased levels of cortisol are associated with stronger feelings of stress. Nevertheless, neither perceived psychological stress nor elevated cortisol levels in a previous tournament predict a subsequent choice between tournaments and fixed payment schemes, indicating that stress induced by incentives schemes is not a relevant criterion for sorting decisions in our experiment. Finally, we find that cortisol levels are severely elevated at the beginning of the experiment, suggesting that participants experience stress in anticipation of the experiment per se, potentially due to uncertainties associated with the unknown lab situation. We call this the novelty effect.
Parenting Deaf Children: Exploring Relationships Between Resolution of Diagnosis, Parenting Styles and Morale, and Perceived Child Vulnerability

Published: April 2023

AbstractRaising a deaf child can have significant impacts on parents’ wellbeing, their relationship with the deaf child, and their ability to parent effectively. Using an online survey, this study explored two questions: First, to examine whether hearing parents treat and perceive their deaf and hearing children differently while controlling for parent characteristics (including resolution of diagnosis), specifically in terms of parenting styles and perceived vulnerability. Second, whether hearing parents’ ability to resolve their feelings about their child’s hearing loss diagnosis was related to their parenting morale, and whether they perceived their deaf child as vulnerable. A total of 84 parents with a deaf child aged 5–12 years completed the survey, with 32 of those also reported about a second child without hearing loss in the same age range. They were asked to answer questions from the Reaction to Diagnosis Interview, and to complete several questionnaires addressing parenting morale, child vulnerability, and parenting styles. Findings suggest that unresolved feelings of diagnosis were linked to lower parenting morale and greater perception of child vulnerability. Sibling comparisons indicated that parents also reported a higher perceived child vulnerability score for the deaf child compared to the hearing sibling. No sibling differences were found regarding parenting styles. These findings suggest that the experience of having a deaf child can have a negative impact on hearing parents’ morale and perception of child vulnerability, particularly when parents remain unresolved about the diagnosis, highlighting the need for targeted supports and further research.

Published: April 2023

AbstractThe quality of parent-child interaction has consistently been associated with child psychosocial outcomes. Postnatal depression (PND) and anxiety (PNA) can have an adverse effect on the parent-child interaction. The Coding Interactive Behaviour (CIB) measure has frequently been used to assess parent-infant interaction quality; however, few have investigated the construct validity. The purpose of this study is to: (1) compare two theoretical models and one data-driven model for best fit and to test the best fitting one for measurement invariance among mothers with and without PND, and (2) compare effects of PND and PNA on the mother-infant interactions. The sample consisted of mothers with PND (n = 236) and a subclinical sample of mothers with elevated symptoms of PND but did not meet criteria for a diagnosis (n = 183) and their infants (aged ≤ 6 months). PND was assessed with a diagnostic interview and PNA using a self-report measure. Confirmatory factor analyses showed that the data-driven model, consisting of the composites ‘Maternal Sensitivity’, ‘Child Engagement’, ‘Maternal Social Withdrawal’, and ‘Maternal Controlling Behaviour’, reached the best fit and showed measurement invariance with regard to PND. Factorial ANOVAs showed no effects of PND and PNA on the composites. The study is the first to investigate and find measurement invariance in the CIB, providing evidence of construct validity. The importance of investigating the factor structure of an instrument liable to change due to contextual factors is discussed.
Empty satisfaction—a social phenomenology of late modern enjoyment
Authors: Sik Domonkos 
Published: April 2023

AbstractPhenomenological analyses of enjoyment are relatively rare; also, the few known attempts (e.g. Levinas) are elaborated in a transcendental fashion, without reflecting on the socio-historical constituents. The article aims at filling this gap by elaborating a social phenomenology of late modern enjoyment. Firstly, the experience is analysed with the help of general phenomenological descriptions: the visceral, existential and ethical constituents are mapped. The second section explores the structural transformations affecting these constituents, based on various critical theories of modernization: the impact of the reified control over the visceral; social disintegration; persistent inequalities; over-burdening of intimacy is analysed. In the concluding section, a diagnosis of times is elaborated: the cost of controlling enjoyment on the visceral level is the giving up of its existential and ethical constituents. To break this paradoxical cycle, the “actor-networks” (Latour) of visceral stimulation need to be “hacked” by including existential and ethical dimensions as well.
Differences in Skill Requirements Between Jobs Held by Immigrant and Native Women Across Five European Destinations

Published: April 2023

AbstractWe examine whether the requirements of analytical skills and physical strength in jobs held by immigrant women in five major European destinations (France, Italy, Spain, Sweden, and the UK) converge to those of jobs of native-born women in their first ten years in the destination country. To this aim, we combine data from the European Labour Force Survey (2005–2015) of immigrant women arriving in these five countries and information about skill requirements from the Occupational Information Network (O*NET). At arrival, migrants in Spain and France use much less analytical skills, but for the period before the Great Recession, that gap closes relatively fast over time compared to other destinations, particularly in the low end of the skill distribution. Physical strength requirements of immigrant’s jobs increase over time and the gaps open in countries where immigrants depart from relatively more strength-intense jobs, while they close in Spain where immigrants use less strength than natives at arrival. Our estimates are also robust to selection into employment both at the average and across the skill distribution using recent techniques. Since the Labour Force Survey does not have information on wages, we use wage information from the European Union Structure of Earnings Survey to proxy average immigrant-native wage gaps implied by our estimated skill gaps by country.
Linguistic modalities and the sources of linguistic utterances
Authors: Drożdżowicz Anna 
Published: April 2023

AbstractAs an object of philosophical study, language is typically considered as an abstract object rather than a lived phenomenon that comes with rich and varied phenomenology. And yet our modes of engaging with language are complex and many. The first goal of this paper is to illustrate this variety by looking at some of the linguistic modalities and forms of communication. The second goal is to suggest that at least in some specific philosophical debates, language and communication should be investigated in the context of the various linguistic modalities and forms of communication. This will be done by considering how attention to some of the linguistic modalities and forms of communication may affect philosophical debates concerning: the nature of words, language and linguistic understanding, as well as the relation between linguistic utterances and their sources.
Mapping enablers for SDG implementation in the private sector: a systematic literature review and research agenda
Authors: Palau-Pinyana Erola , Llach Josep , Bagur-Femenías Llorenç 
Published: April 2023

AbstractAcademics and practitioners alike recognize the important role of businesses in achieving the UN’s Sustainable Development Goals (SDGs). However, research is still needed to understand strategies that can aid the private sector in this regard. The objective of the current paper is twofold. First, it provides an interdisciplinary systematic literature review of 96 papers published between 2015 and 2022 to analyse the state-of-the-art of the academic literature on the enablers that can facilitate SDG implementation in businesses. The analysis provides evidence that enablers can be categorized depending on whether they are external to the company (industry, tools, and education), internal to the company (company characteristics, governance, and adoption of innovation and technology), or a combination of both (Public–Private Partnerships). Second, it provides a specific research agenda on each enabler, offering relevant recommendations for academics, practitioners and policy makers to work simultaneously to achieve the UN’s 2030 Agenda.
In Situ Study of Peritectic Couple Growth Under Purely Diffusive Conditions
Authors: Ludwig Andreas , Mogeritsch Johann 
Published: April 2023

AbstractHerein, in a microgravity campaign onboard the International Space Station, peritectic coupled growth (PCG) is studied by solidifying alloys of the peritectic transparent organic system TRIS–NPG under purely diffusive conditions. The experiment reveals that the formation of PCG begins with coagulated lateral bands comprising the peritectic phase at temperatures below the peritectic one. After reaching the growth front of the pro-peritectic phase, growth competition between both solid phases occurs such that the patches of the pro-peritectic phase, lamellae, and fibers/rods grow in the stated order, coupled with the peritectic phase. As the entire solidification process occurs during the initial transient stage, the diffusion coupling between the two solid phases is weak. With the gradual decrease in the interface temperature during the initial transient, the necessary growth conditions for the pro-peritectic phase diminish. Additionally, different concentrations along the inclined solid/liquid interface favor the peritectic phase at the rear window and the pro-peritectic phase at the front window. The corresponding PCG lasts 19 hours while the recoil of the inclined interface continues to a temperature level that makes alterations of the ‘effective’ TRIS–NPG phase diagram necessary.
Investigating Public Sentiment on Laryngeal Cancer in 2022 Using Machine Learning

Published: April 2023

AbstractThis study aims to investigate public sentiment on laryngeal cancer via tweets in 2022 using machine learning. We aimed to analyze the public sentiment about laryngeal cancer on Twitter last year. A novel dataset was created for the purpose of this study by scraping all tweets from 1st Jan 2022 that included the hashtags #throatcancer, #laryngealcancer, #supraglotticcancer, #glotticcancer, and #subglotticcancer in their text. After all tweets underwent a fourfold data cleaning process, they were analyzed using natural language processing and sentiment analysis techniques to classify tweets into positive, negative, or neutral categories and to identify common themes and topics related to laryngeal cancer. The study analyzed a corpus of 733 tweets related to laryngeal cancer. The sentiment analysis revealed that 53% of the tweets were neutral, 34% were positive, and 13% were negative. The most common themes identified in the tweets were treatment and therapy, risk factors, symptoms and diagnosis, prevention and awareness, and emotional impact. This study highlights the potential of social media platforms like Twitter as a valuable source of real-time, patient-generated data that can inform healthcare research and practice. Our findings suggest that while Twitter is a popular platform, the limited number of tweets related to laryngeal cancer indicates that a better strategy could be developed for online communication among netizens regarding the awareness of laryngeal cancer.
Intergroup Cooperation in Shotgun Hunting Among BaYaka Foragers and Yambe Farmers from the Republic of the Congo

AbstractWhereas many evolutionary models emphasize within-group cooperation or between-group competition in explaining human large-scale cooperation, recent work highlights a critical role for intergroup cooperation in human adaptation. Here we investigate intergroup cooperation in the domain of shotgun hunting in northern Republic of the Congo. In the Congo Basin broadly, forest foragers maintain relationships with neighboring farmers based on systems of exchange regulated by norms and institutions such as fictive kinship. In this study, we examine how relationships between Yambe farmers and BaYaka foragers support stable intergroup cooperation in the domain of shotgun hunting. In the study village, shotgun hunting is based on a specialization-based exchange wherein Yambe farmers contribute shotguns and access to markets to buy cartridges and sell meat while BaYaka foragers contribute their specialized forest knowledge and skill. To understand how costs and benefits are distributed, we conducted structured interviews with 77 BaYaka hunters and 15 Yambe gun owners and accompanied hunters on nine hunting trips. We found that hunts are organized in a conventional manner within a fictive kinship structure, consistent with the presence of intercultural mechanisms to stabilize cooperation. However, because bushmeat demand is high, gun owners can gain significant cash profit, while compensating hunters only with cigarettes, alcohol, and a traditional hunter’s portion of meat. To level payoffs, hunters strategically hide kills or cartridges from gun owners to feed their own families. Our results illustrate how each group prioritizes different currencies (e.g., cash, meat, family, intergroup relations) and provide insights into how intergroup cooperation is stabilized in this setting. The example of this long-standing intergroup cooperative system is discussed in terms of its contemporary entwinement with logging, the bushmeat trade, and growing market intersection.
Ausubel’s meaningful learning re-visited
Authors: Bryce T. G. K. , Blown E. J. 
Published: April 2023

AbstractThis review provides a critique of David Ausubel’s theory of meaningful learning and the use of advance organizers in teaching. It takes into account the developments in cognition and neuroscience which have taken place in the 50 or so years since he advanced his ideas, developments which challenge our understanding of cognitive structure and the recall of prior learning. These include (i) how effective questioning to ascertain previous knowledge necessitates in-depth Socratic dialogue; (ii) how many findings in cognition and neuroscience indicate that memory may be non-representational, thereby affecting our interpretation of student recollections; (iii) the now recognised dynamism of memory; (iv) usefully regarding concepts as abilities or simulators and skills; (v) acknowledging conscious and unconscious memory and imagery; (vi) how conceptual change involves conceptual coexistence and revision; (vii) noting linguistic and neural pathways as a result of experience and neural selection; and (viii) recommending that wider concepts of scaffolding should be adopted, particularly given the increasing focus on collaborative learning in a technological world.
