Authors: Tiscini Riccardo , Ciaburri Mirella , Magnanelli Barbara Sveva , Nasta Luigi 
Published: September 2023

The COVID-19 pandemic has been a disruptive and unexpected event that has impacted businesses worldwide. It is necessary to investigate the characteristics of companies that enable them to face and respond to this critical situation more effectively. The purpose of the present study is to determine whether the presence of a female CEO during unanticipated critical events affects a company’s performance. Given the increasing significance of gender at the highest levels of management, more research has been conducted on female leadership. However, there is limited research on female leadership during disruptive periods and events. Over the course of 3 years (2017–2020), an empirical analysis was conducted on a sample of Italian publicly traded companies, meaning that data was collected and analyzed during the COVID-19 pandemic. The results indicate that female leadership during the pandemic has a positive impact on the performance of the company.

In terms of communications and scientific observations, a stratospheric airship can be an effective alternative to the artificial satellites in Earth’s orbit. For an airship to float in the low air-density stratosphere, it must be designed with light, flexible, and strong materials. In the present study, we have designed and developed six different coated and laminated structures by using high-performance para-aramid fabric, polyvinylidene chloride (PVDC)-coated biaxially oriented polyethylene terephthalate (BOPET), and polyvinyl fluoride (PVF) films. The developed coated and laminated stratospheric airship structures demonstrate excellent performance even in the harsh environmental conditions such as very low atmospheric pressure (∼0.001 atm), extreme temperatures (80°C in the day and −80°C in the night;), high UV irradiation, and ozone as well as atomic oxygen. In order to analyze the effect of the harsh environmental conditions existing in stratospheric atmosphere on physico-mechanical properties such as tensile strength, tear strength, peel strength, and helium (He) gas barrier of the prepared laminate structures, they were evaluated after exposure in simulated accelerated artificial weathering conditions up to 400 h. The developed multilayered laminated structures exhibited superior He-gas permeability (0.04 L/m2/24 h), high tensile strength (>820 N/cm), and good tear strength (401–477 N/cm) with relatively low areal density (207–262 g/m2). Furthermore, all the laminates also demonstrated very low degradation in mechanical properties, that is, 3%–8% in peel strength, 1%–3% in tear strength, and 1%–2% in tensile strength under artificial weathering conditions up to 400 h.
A novel application of titanium suboxide to enhance the flame retardancy, thermal stability, and thermal and electrical conductivity of silicone rubber
Authors: Feng Fengzhen , Xu Siyi , Liu Haodong , Li Jianxi 
Published: September 2023

This study investigates the impact of Titanium Suboxide (Ti4O7) on the flame retardancy, mechanical properties, thermal stability, and electrical and thermal conductivity of silicone rubber composites. The addition of 1.0 part of Ti4O7 to the silicone rubber composites results in a total heat release (THR) of 45 MJ/m2, which is 45.7% lower than the silicone rubber without Ti4O7, leading to a decrease in the peak of heat release rate (PHRR). Furthermore, Ti4O7 exhibits temperature stability at low temperatures and acts as a physical barrier, inhibiting the early decomposition of silicone rubber and enhancing the thermal stability of the composites. However, at temperatures exceeding 450°C, the catalytic activity of Ti4O7 is activated, promoting the decomposition of the silicone rubber composites and generating more residue. The addition of an appropriate amount of Ti4O7 can further improve the mechanical properties of the silicone rubber composites and enhance their electrical and thermal conductivity.

Published: September 2023

Herein, the catalytic effects of aromatic amines with different structures on the room temperature curing of bisphenol E cyanate (BECy) have been studied using differential scanning calorimetry (DSC) and Fourier transform infrared (FT-IR) spectroscopy. Our results revealed that the mixed amine comprised of aniline and N,N-dimethyl-p-phenylenediamine (AN/NNDPA) bearing primary amino groups in its structure was a highly effective catalyst for the room temperature curing of cyanate esters. When the cyanate ester and mixed amine were combined at a molar ratio of 100:5 and cured at room temperature for 5 days, the curing degree of BECy resin reached 79.7%. The room temperature curing mechanism of the BECy-AN/NNDPA system was investigated using pyrolysis gas chromatography-mass spectrometry (PY GC-MS). Our results showed that the formation reactions of the intermediate structure and cyclotrimerization reactions occurred during the room-temperature curing process. The activation energies of BECy and different aromatic amine systems at different heating rates were determined using non-isothermal DSC. The results further demonstrated the catalytic effect of AN/NNDPA on the cyanate ester curing reaction. BECy-AN/NNDPA cured at room temperature has suitable heat resistance and a 5% weight loss temperature (Td5) of 361°C.

Authors: Yeoh Ling H. , Tan Benjamin , Rhee Joel , Sinclair Craig 
Published: September 2023

Background Current literature indicates low uptake of advance care planning (ACP) among the Chinese-speaking community in Australia. To increase the uptake of ACP among the Chinese-speaking community, a better understanding of their attitudes and perceptions on end-of-life (EOL) matters, and ACP is required. Objective This study aimed to identify significant events and social and cultural factors that influence participants’ values and characterize the attitudes and perceptions towards ACP among older Chinese-speaking Australians. Methods A qualitative study explored participants’ experiences through semi-structured one-to-one interviews. The interviews were conducted in Mandarin, Cantonese or English, then translated and transcribed into English. The transcripts were coded and analysed thematically. Results Twenty participants were recruited (14 female, six male). Participants typically reported a preference to make health-related decisions autonomously. Their perspectives were grounded in past experiences of illnesses and EOL decision-making of loved ones, personal values, and perceived needs. Family dynamics and intimacy of relationships appeared to influence the role and responsibility of family members in EOL decision-making and ACP. Most participants perceived the need to engage in ACP only when encountering significant health changes or higher care needs. Conclusion Healthcare professionals should initiate ACP discussion using culturally appropriate communication with consideration of personal values, past experiences and family dynamics. Efforts should be invested in raising public awareness of ACP within the Chinese-Australian community.

Published: September 2023

Background Mental health is defined as a state of emotional, psychological, and social well-being, and has been shown to be positively associated with self-esteem and quality of life. It is important to note that mental health is dynamic and influenced by a wide range of social, biological, and behavioral factors. Therefore, the aim this study was to describe the health-related quality of life and self-esteem in adolescents, examining their relationship with various health indicators, lifestyle habits, and sociodemographic variables. Method A cross-sectional study was conducted with a representative sample of 761 students (14.51 ± 1.63 years). Health-related quality of life, self-esteem, satisfaction with body image, adherence to the Mediterranean diet, physical activity practice, hours of nightly sleep, maximum oxygen consumption, body mass index, academic performance, and various sociodemographic factors of all participants were analyzed. Results Regression analysis showed that body satisfaction and academic performance were associated of both health-related quality of life and self-esteem. Additionally, physical activity, age, and favourable settings for physical activity engagement were also found to be related to health-related quality of life, whilst adherence to the Mediterranean diet, hours of nightly sleep, maximum oxygen consumption and socioeconomic status were associated with self-esteem. Conclusions Given the associations found between health-related quality of life and self-esteem with lifestyle habits and sociodemographic indicators, there is an urgent need to develop interdisciplinary and cross-cutting promotion strategies to improve the mental health of adolescents.
Language contact phenomena in multiword units: The code-switching–calquing continuum
Authors: Hennecke Inga , Wiesinger Evelyn 
Published: September 2023

Aims and objectives: Code-switching and calquing are two widespread language contact phenomena in bilingual speech. While both phenomena have been discussed extensively in research on language contact in the past decades, only very few studies systematically investigate code-switching and calquing of and within multiword units or constructions. In our contribution, we aim at developing a more differentiated account of code-switching and calquing of and within multiword units and constructions, bringing together recent usage-based psycholinguistic and Construction Grammar theories and modeling with cognitively oriented approaches to language contact and bilingualism. Design: We analyze and discuss corpus data from the Corpus of Spanish in Southern Arizona (CESA) from first-, second-, and third-generation bilingual Spanish–English speakers in Arizona. Data and analysis: The corpus analysis focuses on code-switching and calquing of and within N Prep N, NN(N), and Adj N/N Adj patterns (N = noun, Prep = preposition, Adj = adjective). Findings/conclusions: The analysis highlights the importance of both lexically specific multiword units and partially and fully schematic constructions in code-switching and calquing as well as a continuum between constructions situated closer to the lexical or to the syntactic pole. Originality: Whereas multiword sequences have been found to play an important role in (mostly first language [L1]) acquisition, use, and processing, the role of multiword units and constructions in bilingual speech has been much less studied so far. Significance/implications: The study shows that both lexically specific constructions or multiword units as well as partially or fully schematic constructions play a central role in code-switching and calquing. The study argues that code-switching and calquing may ultimately be viewed as a continuum, since the speakers rely on similar, highly frequent, and productive constructions and their interlingual correspondences for both phenomena.
Predicting language dominance in Spanish/English bilingual adults based on relative speech-in-speech recognition scores
Authors: Cowan Tiana , Calandruccio Lauren , Buss Emily , Rodriguez Barbara , Leibold Lori J. 
Published: September 2023

Purpose: Multiple dimensions of language dominance, such as language proficiency and demand for language use, can be reflected in bilinguals’ speech-in-speech recognition scores. This paper explores the feasibility of using a novel measure to estimate language dominance for bilinguals: relative speech-in-speech recognition thresholds (SRTs) or the within-person difference in SRTs between their two languages. Method: Participants were 25 Spanish/English bilingual adults ( Mage = 30 years). SRTs for sentence recognition in a language-matched two-talker masker were measured in English and in Spanish using an adaptive, open-set task. Relative SRTs were calculated by subtracting the Spanish SRT from the English SRT. Language dominance and proficiency were assessed by established measures. Analysis: Spearman correlations were used to assess the association between measures. Findings: Relative SRTs were correlated with dominance scores derived from both a questionnaire ( rs = −.80) and standardized testing ( rs = −.80). Originality: We tested and validated a novel measure, relative SRTs, to predict language dominance in bilingual adults. This time-efficient method could be used by bilingual researchers interested in assessing language dominance for descriptive or experimental purposes. Significance: Relative SRTs show promise as a valid method to assess language dominance in Spanish/English bilingual adults.
It will take time and resources: Changing disability benefits on the way to social model in CEE countries
Authors: Morawski Leszek , Akarsu Mahmut Zeki 
Published: September 2023

Central and Eastern European (CEE) countries have ratified the United Nations Convention on the Rights of Persons with Disability, necessitating adjustments in tax and benefit policies. However, the eventual outcome of these modifications remains uncertain. To evaluate possible changes, we conducted a comparative analysis of current instruments in CEE countries vis-a-vis Sweden, Denmark, and Finland. Our research discovered that tax and benefit systems in both CEE and Scandinavian countries are built on the same foundational principles, yet differ significantly in their specific solutions and approaches. Notably, benefits systems in CEE countries are considerably more intricate and inclined toward means-tested benefits and specialized instruments dedicated solely to individuals with disabilities. We posit that changes arising from the convention’s implementation will streamline the benefits system, incorporating more generalized instruments with disability added as supplementary eligibility conditions or income parameters. The velocity of this transformation will be influenced by the pace of economic growth, as evidenced by the strong positive correlation between disability expenditure’s proportion in gross domestic product and the European Union countries’ level of economic development.

Objective: Transcatheter aortic valve replacement (TAVR) has arisen as a viable alternative to surgery. Similarly, minimally invasive surgical aortic valve replacement (mini-SAVR), such as ministernotomy and minithoracotomy, have also gained interest. We conducted a pairwise meta-analysis to further investigate the efficacy of TAVR versus mini-SAVR. Methods: Medical databases were comprehensively searched for studies comparing TAVR with a mini-SAVR modality, defined as minimally invasive aortic surgery, ministernotomy, minithoracotomy, or rapid-deployment or sutureless SAVR. Random-effects meta-analysis was conducted using the generic inverse variance method. Primary outcomes included 30-day mortality, midterm mortality, 30-day stroke, acute kidney injury (AKI), paravalvular leak (PVL), new permanent pacemaker (PPM), new-onset atrial fibrillation, and postintervention mean and peak valve pressure gradients and were pooled as risk ratio (RR), mean difference (MD), or hazard ratio (HR) with 95% confidence interval (CI). Results: A total of 5,071 patients (2,505 mini-SAVR vs 2,566 TAVR) from 12 studies were pooled. Compared with TAVR, mini-SAVR showed significantly lower rates of both 30-day (RR = 0.63, 95% CI: 0.42 to 0.96, P = 0.03) and midterm mortality at 4 years of follow-up (HR = 0.76, 95% CI: 0.67 to 0.87, P < 0.001). Furthermore, mini-SAVR was protective against 30-day PVL (RR = 0.07, 95% CI: 0.04 to 0.13, P < 0.001) and new PPM (RR = 0.25, 95% CI: 0.11 to 0.57, P < 0.001). Conversely, TAVR was protective against 30-day AKI (RR = 1.67, 95% CI: 1.20 to 2.32, P = 0.002) and postinterventional mean gradients (MD = 1.65, 95% CI: 0.25 to 3.05, P = 0.02). No difference was observed for 30-day stroke (RR = 0.84, 95% CI: 0.56 to 1.24, P = 0.38), new-onset atrial fibrillation (RR = 1.79, 95% CI: 0.93 to 3.44, P = 0.08), or postinterventional peak gradients (MD = 3.24, 95% CI: −1.10 to 7.59, P = 0.14). Conclusions: Compared with TAVR, mini-SAVR was protective against 30-day and midterm mortality, 30-day PVL, and new permanent pacemaker, while TAVR patients had lower 30-day AKI. Future randomized trials comparing the efficacy of mini-SAVR approaches with TAVR are needed.

Background: Improving physical activity levels and diet quality are important for secondary stroke prevention. Aim: To test the feasibility and safety of 6-month, co-designed telehealth-delivered interventions to increase physical activity and improve diet quality. Methods: A 2 × 2 factorial trial (physical activity (PA); diet (DIET); PA + DIET; control) randomized, open-label, blinded endpoint trial. Primary outcomes were feasibility and safety. Secondary outcomes included stroke risk factors (blood pressure, self-report PA (International Physical Activity Questionnaire (IPAQ)) and diet quality (Australian Recommended Food Score (ARFS)), and quality of life. Between-group differences were analyzed using linear-mixed models. Results: Over 23 months, 99 people were screened for participation and 40 (40%) randomized (3 months to 10 years post-stroke, mean age 59 (16) years). Six participants withdrew, and an additional five were lost to follow-up. Fifteen serious adverse events were reported, but none were deemed definitely or probably related to the intervention. Median attendance was 32 (of 36) PA sessions and 9 (of 10) DIET sessions. The proportion of missing primary outcome data (blood pressure) was 3% at 3 months, 11% at 6 months, and 14% at 12 months. Between-group 95% confidence intervals showed promising, clinically relevant differences in support of the interventions across the range of PA, diet quality, and blood pressure outcomes. Conclusion: Our telehealth PA and diet interventions were safe and feasible and may have led to significant behavior change. Trial Registration: ACTRN12620000189921.

Background: Human milk bank is a sustainable source of donor human milk (DHM) which is an acceptable alternative to the mother’s milk and it is not routinely available in Nigeria, a multi-ethnically diverse country. The study aimed to assess the willingness to donate or accept human milk among pregnant women and mothers attending the antenatal, immunization, outpatient, under-five, and neonatal follow-up clinics in selected health facilities in Ekiti State, Southwest Nigeria. Study Design and Methods: A descriptive cross-sectional, mixed methods study design was used to collect data in selected health facilities in Ekiti State. Questionnaires and focus group discussions were used to collect quantitative and qualitative data respectively while data analysis was done using the IBM® Statistical Package for Social Science SPSS version 26® and thematic analysis respectively. Results: Of the 798 respondents, 529 (66.3%) and 626 (78.4%) did not know about wet nursing or human milk banking (HMB) respectively and 139 (17.4%) were willing to donate their breastmilk for a stipend. In the focus group discussion, 50% had heard about wet nursing but none heard about HMB. Maternal educational level had a significant impact on their willingness to donate or accept DHM ( p < 0.00). Wholesomeness, cultural, and religious biases were major reasons affecting HMB acceptability. Conclusions: Awareness and perception of HMB are poor. Appropriate information, education, and counselling on HMB are needed to drive the adoption and establishment of HMB in Nigeria.

Introduction: Patent foramen ovale (PFO)-closure is recommended for stroke prevention in selected patients with suspected PFO-associated stroke. However, studies on cerebrovascular event recurrence after PFO-closure are limited by relatively short follow-up periods and information on the underlying aetiology of recurrent events is scarce. Patients and methods: All consecutive patients with a cerebral ischaemic event and PFO-closure at the University Hospital Graz were prospectively identified from 2004 to 2021. Indication for PFO-closure was based on a neurological-cardiological PFO board decision. Patients underwent standardized clinical and echocardiographic follow-up 6 months after PFO-closure. Recurrent cerebrovascular events were assessed via electronical health records. Results: PFO-closure was performed in 515 patients (median age: 49 years; Amplatzer PFO occluder: 42%). Over a median follow-up of 11 years (range: 2–18 years, 5141 total patient-years), recurrent ischaemic cerebrovascular events were observed in 34 patients (ischaemic stroke: n = 22, TIA: n = 12) and associated with age, hyperlipidaemia and smoking in multivariable analysis ( p < 0.05 each). Large artery atherosclerosis and small vessel disease were the most frequent aetiologies of recurrent stroke/TIA (27% and 24% respectively), and only two events were related to atrial fibrillation (AF). Recurrent ischaemic cerebrovascular event rates and incident AF were comparable in patients treated with different PFO occluders ( p > 0.1). Discussion and conclusion: In this long-term follow-up-study of patients with a cerebral ischaemic event who had received PFO-closure with different devices, rates of recurrent stroke/TIA were low and largely related to large artery atherosclerosis and small vessel disease. Thorough vascular risk factor control seems crucial for secondary stroke prevention in patients treated for PFO-related stroke.
