Contextual factors influencing talk in Australian residential aged care
Authors: Scerri Madalyn Anne , Presbury Rajka 
Published: May 2021

PurposeThis paper offers an exploration of contextual factors that influence carer-to-resident talk in Australian residential aged care.Design/methodology/approachA qualitative exploratory multiple case study methodology and a theoretical framework of service language were applied to explore the perspectives of 21 registered nurses, assistants in nursing, leisure and lifestyle officers, general managers and care managers at three residential aged care homes in Australia.FindingsThe findings demonstrate contextual factors related to the care home environment, the carer and the relationship between carers and residents that impede or enable carer-to-resident talk in residential aged care. Multiple factors related to the care home environment were found to impede carer-to-resident talk, including time pressures, staffing levels, team culture and the prioritisation of tasks. Factors related to carers had potential to either impede or enable talk, including carers' awareness of the importance of communication, level of experience and individual characteristics, values and attitudes. A strong relationship between a carer and resident built on knowledge of individuals was a key enabling factor.Originality/valueThe paper advances an understanding of factors that influence talk and interaction in residential aged care in Australia from carers' and care home leaders' perspectives. The findings can be used to support verbal communication management strategies aligned with a person-centred care approach, including training and development of staff, cultural change interventions and a review of care delivery procedures.
Mobile learning acceptance and use in higher education during social distancing circumstances: an expansion and customization of UTAUT2
Authors: Sitar-Taut Dan-Andrei , Mican Daniel 
Published: May 2021

PurposeThis paper investigates if the existing degree of students' acceptance and use of mobile or m-learning may face the online shift determined by SARS-CoV-2. Based on the extended unified theory of acceptance and use of technology (UTAUT2), a new comprehensive model, SD-UTAUT (social distancing-UTAUT), is developed to better understand relationships between the original constructs, plus personal innovativeness (PI) and information quality (IQ). It identifies the key factors affecting behavioral intention (BI) and use by examining the influence of revaluated hedonic motivation (HM) and learning value (LV) importance as mediators.Design/methodology/approachThe paper opted for an exploratory study involving 311 learners, using partial least squares structural equation modeling (PLS-SEM).FindingsSD-UTAUT can be a new m-learning model in higher education. It has high predictive power and confirmed 15 out of 16 hypotheses. The most powerful relationship is between performance expectancy (PE) and HM. IQ affected LV the most, since HM the behavioral use (BU). HM impacts the use behavior (UB) more than LV, but habit (HT) affects it the most.Research limitations/implicationsBecause of the pandemic context, output may lack generalizability and reproducibility.Practical implicationsTo improve usage, staff must provide better support, course creators emphasize the objectives and competencies and developers integrate innovation. The joy and pleasure of m-learning use may stimulate the LV through interesting and interactive content, like incorporating gamification.Originality/valueThe model set-up and circumstances are previously unseen. SD-UTAUT confirms ten new hypotheses and introduces the student's grade point average (GPA) as a moderator.Peer reviewThe peer review history for this article is available at https://publons.com/publon/10.1108/OIR-01-2021-0017
How Meeting Centres continue to support people affected by dementia: report on UK COVID-19 impact
Authors: Evans Shirley , Bray Jennifer , Brooker Dawn 
Published: May 2021

Purpose
Because of COVID-19 restrictions, Meeting Centres (MCs) for people affected by dementia in the UK ceased to meet physically but continued to provide remote support. The aim was to understand the extent to which MCs were able to operate when physical meetings were not possible and how they achieved particularly in relation to the adaptation and coping model and practical, emotional and social adjustment.

Design/methodology/approach
Semi-structured interviews and focus groups were conducted with people affected by dementia, staff, volunteers, managers and trustees from MCs. Data were collected on the type and quantity of contact MCs had with people affected by dementia during lockdown. Data were coded and mapped against adaptation and coping strategies, i.e. practical understanding and empowerment, optimising emotional well-being and opportunities for social engagement.

Findings
A range of remote approaches, both technological (e.g. using online platforms) and non-technological (e.g. newsletters and post) were implemented alongside limited face-to-face contact. Regular MC activities were adapted using the different approaches. It was possible to map all the adaptation and coping model support strategies to the activities delivered in this way. MCs were able to adapt rapidly to continue to support people to adjust to change.

Social implications
Moving forward, combining approaches (usual MC and remote) means person-centred support could be optimized, addressing social isolation and reaching those who cannot attend MCs.

Originality/value
This paper offers new insight into the extent to which community-based support for people with dementia can continue when face-to-face contact is not possible because of COVID-19.
Biodiversity and ecosystem functioning: Have our experiments and indices been underestimating the role of facilitation?

Abstract

After 25 years of biodiversity experiments, it is clear that higher biodiversity (B) plant communities are usually more productive and often have greater ecosystem functioning (EF) than lower diversity communities. However, the mechanisms underlying this positive biodiversity–ecosystem functioning (BEF) relationship are still poorly understood.

The vast majority of past work in BEF research has focused on the roles of mathematically partitioned complementarity and selection effects. While these mathematical approaches have provided insights into underlying mechanisms, they have focused strongly on competition and resource partitioning.

Importantly, mathematically partitioned complementarity effects include multiple facilitative mechanisms, including dilution of species‐specific pathogens, positive changes in soil nutrient cycling, associational defence and microclimate amelioration.

Synthesis. This Special Feature takes an experimental and mechanistic approach to teasing out the facilitative mechanisms that underlie positive BEF relationships. As an example, we demonstrate diversity‐driven changes in microclimate amelioration. Articles in this Special Feature explore photoinhibition, experimental manipulations of microclimate, lidar examinations of plant canopy effects and higher‐order trophic interactions as facilitative mechanisms behind classic BEF processes. We emphasize the need for future BEF experiments to disentangle the facilitative mechanisms that are interlinked with niche complementarity to better understand the fundamental processes by which diversity regulates life on Earth.

Published: May 2021

AbstractThis paper describes how the Thai health sector developed nationwide emergency medical services (EMS), despite limited resources and we try to extract lessons applicable to other resource‐constrained settings. The government of Thailand has strengthened EMS by integrating it into the general healthcare system and formulating a national development plan and lead agency for EMS. The government emphasized the deployment of low‐cost basic‐level EMS units stationed near the communities, named as ‘first‐responder units’. In Khon Kaen Province, which has led the nationwide EMS development of Thailand, the availability of EMS (number of EMS units) and utilisation of EMS (proportion of severe trauma patients transported to hospital by EMS) greatly increased from 2000 to 2017. This success is due to the emphasis on the first‐responder units through consistent national policies.
Pay inequality and gender dynamics in top executive positions
Authors: Amore Mario Daniele , Garofalo Orsola 
Published: May 2021

AbstractResearch Question/IssueContributing to ongoing debates on the determinants of diversity at the helm of companies, we investigate the relationship between executives' gender and pay inequality within the top executive team.Research Findings/InsightsUsing a panel data set of US listed firms, we find that a greater inequality in executive pay is positively associated with the exit of female executives from the firm's top executive team. This effect is economically larger when the starting level of female representation in the executive team is low, when the firm uses more variable compensation to reward executives, and when the firm operates in geographic areas featuring stronger aversion toward income inequality.Theoretical/Academic ImplicationsOur study expands existing knowledge on the organizational and external factors promoting gender diversity at the top of companies. Although this literature has widely analyzed women's entry into corporate positions, exit has been largely neglected. Our study fills this gap by documenting significant gender differences in the relationship between executives' pay inequality and exit from the top executive team. In so doing, we connect the literatures on gender diversity and executive pay distribution, which have developed in a rather independent manner.Practitioner/Policy ImplicationsDrawing on insights from corporate governance and behavioral economics, this study offers novel evidence to policy‐makers interested in addressing the under‐explored challenges associated with the retention of women in corporate positions and their upward mobility within the corporate hierarchy. Moreover, the contextual variations behind our main finding suggest that cultural values and norms may play a key role in shaping the effectiveness of public policies aimed at increasing diversity in corporate governance positions.

Published: May 2021

AbstractBackground and purposeThis study was undertaken to investigate migraine prevalence in persons with hallucinogen persisting perception disorder (HPPD) presenting as visual snow syndrome (VSS).MethodsPersons with visual snow as a persisting symptom after illicit drug use (HPPD) were recruited via a Dutch consulting clinic for recreational drug use. A structured interview on (visual) perceptual symptomatology, details of drugs use, and medical and headache history was taken. As a control group, persons with visual snow who had never used illicit drugs prior to onset were included. The primary outcome was lifetime prevalence of migraine. Symptom severity was evaluated by the Visual Snow Handicap Inventory (VHI), a 25‐item questionnaire.ResultsNone of the 24 HPPD participants had migraine, whereas 20 of 37 (54.1%) controls had migraine (p < 0.001). VHI scores did not differ significantly between the two groups; in both groups, the median score was 38 of 100. In most HPPD cases (17/24, 70.9%), visual snow had started after intake of ecstasy; other psychedelic drugs reported included cannabis, psilocybin mushrooms, amphetamine, 4‐fluoroamphetamine, 3‐methylmethcathinone, 4‐Bromo‐2,5‐dimethoxypenethylamine, and nitrous oxide.ConclusionsWhereas none of the HPPD participants had migraine, more than half of the visual snow controls without prior use of illicit drugs had migraine. This suggests that at least partly different pathophysiological factors play a role in these disorders. Users of ecstasy and other hallucinogens should be warned of the risk of visual snow. Further studies are needed to enhance understanding of the underlying neurobiology of HPPD and VSS to enable better management of these conditions.

AbstractUnderstanding alteration mechanisms of borosilicate glasses in aqueous media is essential to nuclear waste performance assessments to ensure radioisotopes are contained for extended durations. Aluminum is typically added to glass compositions to reduce the extent of alteration. However, previous work on 7‐day durability tests has suggested that Al has a nonlinear relationship with extent of alteration. The effects of Al:Si and (Al+Na):Si substitutions on glass durability were evaluated using series of glasses based on the International Simple Glass corroded in static conditions up to 13 months in deionized water at 90°C. The alteration behavior was determined by measurement of element release in solution. The ⁓7‐day alteration trends across the series were consistent with predicted trends. The 13‐month results indicated overall alteration decreased as Al:Si ratios increased and was unaffected by changes in (Al+Na):Si except for the glass with the highest (Al+Na):Si ratio (ISG‐A23N), which completely altered within 14 days. Frequent sampling and in situ Raman measurements of solutions revealed ISG‐A23N experienced several distinguishable alteration rate regimes within 7 days, forming a ⁓100 µm alteration layer and a NaSiAlO4 zeolite.

AbstractBackgroundThe original English version of the questionnaire ‘Parental Perceptions of SDF Dental Color Changes’ was used among parents in the New York City metropolitan area.AimTo develop an Italian version of the questionnaire and to assess its validity.DesignThe construct validity and the internal consistency were assessed in a convenience sample of Italian parents of 251 young healthy children seen at the University of Bologna and Pisa. Forward‐backward technique was carried out for the translation of the questionnaire. Kaiser‐Meyer‐Olkin measure of sampling adequacy was equal to 0.91, and Bartlett's test of sphericity was statistically significant (P = .001), so the items were treated with the exploratory principal component analysis (PCA).ResultsCronbach's alpha ranged from 0.69 to 0.95. PCA demonstrates that all the items load on the first component (87% of explained variance). All the Spearman correlation coefficients between each subscale (positive scenario: 0.563; negative scenario: 0.665) and the general acceptability showed significant correlation (P = .0001). Different age, educational level, and family income of the parents did not produce statistically significant different scores on any of the subscales (P > .05; Mann‐Whitney test).ConclusionThe Italian version of the questionnaire showed high internal consistency and construct validity and was appropriate to be used in an Italian population.
A new era of moisturizers
Authors: Chandan Neha , Rajkumar Jeffrey R. , Shi Vivian Y. , Lio Peter A. 
Published: May 2021

AbstractBackgroundMoisturizers traditionally function to replenish both the intercellular lipid lamella and natural moisturizing factors, and form a hydrolipid film on the skin surface to decrease transepidermal water loss and improve hydration. As we continue to identify epidermal lipid imbalance in patients with atopic dermatitis, we turn to the use of bioactive ingredients in moisturizers for improving barrier repair and function.MethodsThis review aims to explore the modern use of moisturizers in targeting various components of the skin barrier, dampening immune response, and restoring microbial balance. We conducted a balanced and comprehensive narrative review of the literature. Studies were identified by searching electronic databases (MEDLINE and PubMed), focusing on studies and trials regarding moisturizers that include endocannabinoids, bioactive lipids, anti‐inflammatory agents, antioxidants, and microbiome modulators. Only articles published in English language were included.ResultsThe aforementioned ingredients exert additional biological effects to improve skin function by upregulating lipid synthesis, decreasing neurosensory transmission of itch signals, reversing oxidative stress, decreasing inflammatory cell activity and cytokine release, and modulating skin microbiota. The shift from traditional moisturizers to those with bioactive ingredients, anti‐inflammatory agents, and microbiome modulating effects opens a realm of possible therapeutic options for patients with barrier‐defective cutaneous conditions.ConclusionFocusing on the disrupted skin barrier as a target for both prevention and treatment and incorporating a combined strategy that utilizes the aforementioned agents to tackle barrier dysfunction from different angles remains a promising area for clinical impact in dermatology.

AbstractA range of liquid emollient ester‐loaded body emulsions were evaluated on the basis of sensory profile, consumer perception, physicochemical, biometrological, and rheological performances. This was complemented by skin hydration and transepidermal water loss (TEWL) studies performed using a Corneometer® and Tewameter®, respectively. The rheological studies showed similar behavior of creams on variation of shear stress, frequency, and temperature. However, skin hydration performances of creams were found varied when compared between base cream and emollient ester‐containing creams. In case of the TEWL study, base cream (F1, no ester) and octyl palmitate‐containing cream (F2), exhibited the most protective behavior for the skin with minimal water loss. Sensory profiles of creams were obtained using the sensory descriptive analysis method. A study performed with human consumers (as subjects) using the difference of test attributes (directional) method showed the importance of sensory evaluation with consumers and proved to be an interesting analysis for comparison with the sensorial profile. In this case, the attributes with the highest intensity in the evaluated creams were, that is, spreadability, slipping, and dry touch. Stability studies of creams were performed for 90 days under different storage conditions. Stability studies showed octyl stearate‐containing (F2) and palmitate‐containing (F5) creams exhibited best stability under extended storage conditions. This research has demonstrated the importance of physicochemical characterization and sensory evaluations performed with consumers for more targeted analysis of cream‐based formulations to differentiate product characteristics and identify attributes‐led preferences.Practical applicationsResults from the present work suggest that emollients are directly responsible for sensory characteristics such as spreading, absorption, and touch on the skin; they can influence the viscosity and appearance of emulsions. After application on the skin, they regulate the moisture content of the epidermis together with the humectants. This research has demonstrated the importance of sensory evaluation, especially performed with consumers, which may be considered a more targeted analysis to differentiate product characteristics and help in the choice of emollient with the desired characteristics for the cosmetic product.

Published: May 2021

AbstractAs a result of increased research and development, people suffering from celiac disease have more options for gluten‐free (GF) products; but we still lack information about celiac consumer's opinions on GF food and whether their requirements are met by currently available products. In this study, we analyzed celiac consumers' opinions and perceptions on commercially available GF products—particularly bread—and provided insights for food scientists and producers. To this end, we applied projective techniques of sentence completion task, word association, free listing, and open‐ended questions. A total of 205 celiac consumers completed the online survey. Despite the rise of the GF market, celiac patients are dissatisfied with the taste, texture, price, and availability of GF products. Bread is a staple GF product, consumed daily by 93% of the participants. Results show that consumers expect improvements that result in the production of soft, moist, and tasty GF bread, with lower price and better availability.Practical ApplicationsThis study provides understanding about the celiac consumers' opinions, expectations and perceptions about gluten free products using projective techniques. Its results will help: (a) define strategies to improve sensory aspects, especially taste, texture and price of gluten‐free breads; (b) increase awareness and understanding of the food industry with information on perceptions that can be used when developing or enhancing commercially available products on the market. This study shows the effectiveness of projective techniques in obtaining consumer opinions on quality aspects of gluten‐free bread.
