Sustainable development through frugal innovation: the role of leadership, entrepreneurial bricolage and knowledge diversity
Authors: Iqbal Qaisar , Piwowar-Sulej Katarzyna , Kallmuenzer Andreas 
Published: April 2024

Abstract
Frugal innovation through frugal functionality, frugal cost, and frugal ecosystems that reduce goods to their essential features has emerged as a highly effective method to improve sustainable development across societies, in developed countries as well as in developing countries. Drawing on social exchange theory and effectuation theory, this study examines the indirect effect of diversified knowledge sharing on the relationship of sustainability-oriented leadership with frugal innovation and the conditional role of entrepreneurial bricolage. The study utilized data collected from 223 representatives of small and medium enterprises in Poland. Partial least squares structural equation modelling was used to test the proposed hypotheses. The results confirmed that sustainability-oriented leadership indirectly and significantly affects frugal functionality and costs through both internal and external diversified knowledge sharing. Yet, internal diversified knowledge sharing does not mediate the sustainability-oriented leadership–frugal ecosystem relationship. The findings show that the sustainability-oriented leadership–external diversified knowledge sharing relationship amplifies with increasing values of entrepreneurial bricolage. However, the sustainability-oriented leadership–internal diversified knowledge sharing relationship does not change in the presence of entrepreneurial bricolage. This pioneering study explores the interactions between sustainability-oriented leadership, entrepreneurial bricolage, and internal as well as external diversified knowledge sharing with regards to frugal innovation. It uncovers the underlying processes of frugal innovation and improved frugal innovation performance, facilitates the integration of knowledge, recognises successful approaches to leadership, creates initiatives for leadership development, and offers actionable insights for organisations aiming to cultivate frugal innovation.
Investigation of emissions from passenger flights Denizli Çardak Airport, Türkiye
Authors: Çil Mehmet Ali , Tarhan Cevahir 
Published: April 2024

AbstractDue to developing aviation sector, number of aircraft in the world is increasing. Along with this development, problems such as the decrease in air quality in and around the airport also arise. In this study, it is tried to calculate pollutant emissions occurring in 2022 during the LTO cycles of Denizli Çardak Airport in Turkey. These calculations are based on the information obtained from ICAO Engine Emission Data Bank and flight information published by the General Directorate of State Airports Authority (GDSAA). As a result of the data obtained, 74.64 ton/year pollutants (NOx-37.148 t/y, CO-35.398 t/y and HC-2.094 t/y) were calculated for 2022 at Denizli Çardak Airport. Of all emissions, NOx accounted for 50%, CO 47% and HC 3%. In the LTO cycle, the most fuel is burned in taxi cycle and pollutant emissions produced in this cycle are greater. With a 2 min reduction in taxi time, there will be an approximate 6.8% reduction in the total emission rate in the LTO cycle. Similarly, with a 4 min reduction in taxi time, there will be a 13.72% reduction in the whole emission rate in the LTO cycle. Unlike other studies, in this study the emission rates of various engines were compared. It has been calculated that the amount of pollutant emissions produced by the new generation Boeing 737 MAX LEAP-1B powered aircraft in LTO cycle is 25% less than the amount of pollutant emissions produced by the Airbus A320 NEO LEAP-1 A powered aircraft. The biggest factor here is that the emission of CO pollutants is less. Considering the emission rates produced by these four different engines (B737-800 CFM56-7B, A320 V2500-A1, B737 MAX LEAP-1B, A320 NEO LEAP-1 A), the Airbus A320 V2500-A1 engine is a more environmentally friendly engine than the other engines.

Abstract
Introduction
Growth hormone deficiency occurs when the pituitary gland does not produce enough growth hormone. Norditropin®, a recombinant human growth hormone, and Sogroya®, an albumin-binding growth hormone derivative, are prescribed for patients with growth hormone deficiency. This systematic review assesses the efficacy, safety, and patient satisfaction associated with Norditropin and Sogroya.

Methods
We systematically searched PubMed, Web of Science, and Scopus databases to identify eligible comparative studies. All studies published until June 2023 were included in our analysis. Our outcomes for children included height velocity and height velocity standard deviation score. In contrast, adult outcomes included adverse events, insulin-like growth factor 1-standard deviation score (IGF-1 SDS), and the Treatment Satisfaction Questionnaire for Medication-9 (TSQM-9). Results are reported as odds ratio (OR) and mean difference (MD) with a 95% confidence interval (95% CI).

Results
Ten studies involving 1058 participants (665 children and 393 adults) were included in the meta-analysis. In children, Norditropin at doses of 0.034 and 0.067 mg/kg/day was compared to Sogroya at doses of 0.04, 0.08, 0.16, and 0.24 mg/kg/week. The results showed that 0.034 mg/kg/day Norditropin had a favorable impact on height velocity (MD −2.01, 95% CI −3.7 to −2.12, p < 0.00001) and height velocity standard deviation score (Mean Difference −3.61, 95% CI −5.06 to −2.16, p < 0.00001) when compared to Sogroya 0.04 mg/kg/day. Other doses showed comparable results. In adults, the only significant side effect noted was rash, which favored Sogroya (OR 0.1, 95% CI 0.04–0.27, p < 0.00001). Additionally, IGF-1 SDS was significantly higher in the Sogroya group than in the Norditropin group (MD 0.25, 95% CI 0.02–0.48, p = 0.03). Furthermore, the overall score of the TSQM-9 questionnaire, which includes three domains: convenience, effectiveness, and satisfaction, was significantly higher in the Sogroya group compared to the Norditropin group (OR 6.36, 95% CI 3.92–8.8, p < 0.00001).

Conclusion
Norditropin and Sogroya showed comparable efficacy and safety profiles, except for the prevalence of rash in the Norditropin group, and Sogroya has higher satisfaction among adults. More high-quality studies with more patients are required to confirm these results.
Travelling wave solution of fourth order reaction diffusion equation using hybrid quintic hermite splines collocation technique
Authors: Priyanka Priyanka , Mebarek-Oudina Fateh , Sahani Saroj , Arora Shelly 
Published: April 2024

AbstractFourth order extended Fisher Kolmogorov reaction diffusion equation has been solved numerically using a hybrid technique. The temporal direction has been discretized using Crank Nicolson technique. The space direction has been split into second order equation using twice continuously differentiable function. The space splitting results into a system of equations with linear heat equation and non linear reaction diffusion equation. Quintic Hermite interpolating polynomials have been implemented to discretize the space direction which gives a system of collocation equations to be solved numerically. The hybrid technique ensures the fourth order convergence in space and second order in time direction. Unconditional stability has been obtained by plotting the eigen values of the matrix of iterations. Travelling wave behaviour of dependent variable has been obtained and the computed numerical values are shown by surfaces and curves for analyzing the behaviour of the numerical solution in both space and time directions.
Longer Term Follow-up on Acuity Circle Allocation Strategies in Liver Transplantation
Authors: Kwong Allison J. , Jowell Ashley , Bambha Kiran , Biggins Scott W. 
Published: April 2024

Abstract
Purpose of Review
This review summarizes longer term follow-up of acuity circle–based distribution for livers, which was implemented on February 4, 2020.

Recent Findings
After 2 years of policy implementation, the likelihood of transplant increased, while removals for death or being too sick decreased. The median transplant score was unchanged, and the variance in the median MELD at transplant decreased for OPTN regions, DSA, and state. Concurrently, median distance from donor to transplant hospital and cold ischemia times increased. A slight increase in liver non-use rate and decrease in liver utilization rate has been observed.

Summary
Acuity circle–based distribution improved access to liver transplantation for the sickest patients through broader sharing, at the cost of increased travel and logistics. The continuous distribution framework may be an opportunity for the liver transplant community to further address geographic disparities in access to transplant in the United States.
Comment: Injuries that Hurt – A Comment to “Embitterment – Conception of a Potential Moderator to Dysfunctional and Aggressive Behaviour in Children and Adolescents”
Authors: Hardecker David J. K. , Schmitz Julian 
Published: April 2024

AbstractThis comment discusses the article of Balder and Linden (2022), who debate the existence and role of embitterment in child and adolescent psychopathology. This topic appears highly relevant, but broader literature should be integrated when talking about embitterment. First, we question the conceptualization of embitterment as an emotion. We conceptualize it as a long-term emotion episode that stems from events involving severe and unresolved hurt feelings, also referred to as attachment injuries and narcissistic injuries. When overly intense, they might lead to PTED. In contrast to Balder and Linden (2022), we argue that specific psychotherapeutic treatments exist. Nonetheless, we join Balder and Linden (2022) in calling for more attention for embitterment and hurt feelings and their role in developmental psychopathology.
Effect of Two-Step Solution Treatments on the Microstructure and Mechanical Properties of B357 Aluminum Alloy

Published: April 2024

Abstract
This study investigates the effect of two-step solution treatments and aging times on the microstructure and mechanical properties of B357 Al–Si alloy, part of the most widely used cast aluminum alloy. Three sets of artificial aging heat treatments were conducted on the tensile samples prepared from B357 alloy produced by low-pressure die casting. Firstly, the conventional artificial aging heat treatment (T6) was carried out by solutionizing the tensile samples at 543 °C for 8.5 h, water quenching at 60 °C, and then artificially aging for 8.5 h at 160 °C. In the two-step solution treatment, the samples were solutionized at 400, 440, 480, and 520 °C for 4 h and then solutionized at 543 °C for 8.5 h and water quenched to 60 °C and then artificially aged for 8.5 h at 160 °C. Thirdly, the samples were solutionized at 480 °C for 4 h, solutionized at 543 °C for 8.5 h, water quenched to 60 °C, and artificially aged for 3–192 h. Despite different solutioning and aging processes, no significant differences were observed in the microstructures of the samples. Si particle coarsening was observed with increasing solution temperature (400–520 °C) and aging times (3–192 h). Si-containing dispersoids and dispersoid-free zones (DFZ) were observed in the primary-α matrix. While DFZ width increased with temperature and aging, dispersoid zones in primary-α dendrites significantly decreased. Differential Scanning Calorimetry (DSC) analysis shows that two-step solution treatment in B357 alloy increases β′ precipitates for Mg2Si precipitation strengthening. The two-step solutionized and aged sample showed the best combination of strength and ductility among all aged samples. B357 alloy exhibited the highest yield and tensile strength (309.7, 366.1 MPa) with 6% elongation for two-step solutionizing and 48 h aging. All aged B357 alloys showed ductile fracture as the primary fracture mode. However, brittle fractured Si particles were observed on the fracture surfaces.
COVID-related stressors, psychological distress and social support in Atlantic Canadian University students
Authors: Fowler Ken , Escoto-Rivera Andrea Lorena , Hesson Jacqueline , Button Pamela 
Published: April 2024

AbstractThis study explores the impact of the COVID-19 pandemic on Memorial University of Newfoundland (MUN) undergraduate and graduate students. Using the National College Health Assessment (third revision) (NCHA-III) survey, the relationship between COVID-related stressors and mental health was assessed after controlling for demographic, economic, and academic variables, and reported mental illness. A hierarchical regression revealed that psychological distress was higher for students who were undergraduate, female, of lower family income, with a pre-existing anxiety or depressive disorder. Psychological distress was also predicted by direct COVID stressors (e.g., fear of infection), as well as indirect stressors, including worries about employment and tuition, professor/instructor support, campus efforts to ensure safety, and discrimination/hostility due to race/ethnicity. Chi Square tests subsequently revealed that graduate students were more likely to be concerned about the threat COVID-19 posed to loved ones, separation from family/friends, and pandemic duration, while undergraduates were more likely concerned about returning to school, tuition, employment, and the legitimacy of their degree. Undergraduates were also more likely to have witnessed discrimination/hostility, and less likely to report professor/instructor support. Finally, independent t tests revealed that undergraduate students were significantly lower in overall social support, as well as for particular subdomains including ‘guidance’, ‘social integration’, and ‘reassurance of worth’. Interpretation of the findings and implications are considered.
Khintchine-type double recurrence in abelian groups
Authors: ACKELSBERG ETHAN 
Published: April 2024

Abstract
We prove a Khintchine-type recurrence theorem for pairs of endomorphisms of a countable discrete abelian group. As a special case of the main result, if

$\Gamma $

is a countable discrete abelian group,

$\varphi , \psi \in \mathrm {End}(\Gamma )$

, and

$\psi - \varphi $

is an injective endomorphism with finite index image, then for any ergodic measure-preserving

$\Gamma $

-system

$( X, {\mathcal {X}}, \mu , (T_g)_{g \in \Gamma } )$

, any measurable set

$A \in {\mathcal {X}}$

, and any

${\varepsilon }> 0$

, there is a syndetic set of

$g \in \Gamma$

such that

$\mu ( A \cap T_{\varphi(g)}^{-1} A \cap T_{\psi(g)}^{-1} A ) > \mu(A)^3 - \varepsilon$

. This generalizes the main results of Ackelsberg et al [Khintchine-type recurrence for 3-point configurations. Forum Math. Sigma10 (2022), Paper no. e107] and essentially answers a question left open in that paper [Question 1.12; Khintchine-type recurrence for 3-point configurations. Forum Math. Sigma10 (2022), Paper no. e107]. For the group

$\Gamma = {\mathbb {Z}}^d$

, the result applies to pairs of endomorphisms given by matrices whose difference is non-singular. The key ingredients in the proof are: (1) a recent result obtained jointly with Bergelson and Shalom [Khintchine-type recurrence for 3-point configurations. Forum Math. Sigma10 (2022), Paper no. e107] that says that the relevant ergodic averages are controlled by a characteristic factor closely related to the quasi-affine (or Conze–Lesigne) factor; (2) an extension trick to reduce to systems with well-behaved (with respect to

$\varphi $

and

$\psi $

) discrete spectrum; and (3) a description of Mackey groups associated to quasi-affine cocycles over rotational systems with well-behaved discrete spectrum.
Predictability Puzzles
Authors: Eraker Bjørn 
Published: April 2024

Abstract
Dynamic equilibrium models based on present value computation not only imply that returns are predictable but also generate particular short-term patterns of predictability in asset returns. I take advantage of this to construct a set of tests of equilibrium generated predictability (EGP). I apply the tests to document two puzzles: First, option-implied or realized measures of volatility ought to predict returns but do not; and second, the variance risk premium (VRP) predicts returns but only at long horizons. VRP fails the tests of EGP as the term structure of predictable variation is inconsistent with an equilibrium interpretation.
The role of linguistic factors in the retention of verbatim information in reading: An eye-tracking study on L1 and L2 German
Authors: Opitz Andreas , Bordag Denisa , Furgoni Alberto 
Published: April 2024

AbstractWe investigated the retention of surface linguistic information during reading using eye-tracking. Departing from a research tradition that examines differences between meaning retention and verbatim memory, we focused on how different linguistic factors affect the retention of surface linguistic information. We examined three grammatical alternations in German that differed in involvement of changes in morpho-syntax and/or information structure, while their propositional meaning is unaffected: voice (active vs. passive), adverb positioning, different realizations of conditional clauses. Single sentences were presented and repeated, either identical or modified according to the grammatical alternation (with controlled interval between them). Results for native (N = 60) and non-native (N = 58) German participants show longer fixation durations for modified versus unmodified sentences when information structural changes are involved (voice, adverb position). In contrast, mere surface grammatical changes without a functional component (conditional clauses) did not lead to different reading behavior. Sensitivity to the manipulation was not influenced by language (L1, L2) or repetition interval. The study provides novel evidence that linguistic factors affect verbatim retention and highlights the importance of eye-tracking as a sensitive measure of implicit memory.
‘I can still swing a spade’: a qualitative exploratory study of gardening groups for people with dementia
Authors: Foster-Collins Helen , Calitri Raff , Tarrant Mark , Orr Noreen , Whear Rebecca , Lamont Ruth A. 
Published: April 2024

Abstract
This exploratory qualitative study aimed to evidence how community-based gardening groups can be used to support the psychological, physical and social health of those living with dementia. The views of people living with dementia in the community, care partners and group leaders were sought to better understand the benefits gained from gardening groups, as well as the features of gardening groups that are cited as enabling positive outcomes. Going beyond the existing single-group studies in this area, this research aimed to identify common themes across multiple gardening groups. Semi-structured interviews were conducted with six group leaders, three people living with dementia and ten care partners from seven gardening groups, either in person or remotely. Thematic analysis of the interview transcripts highlighted broad enablers – ‘the garden setting’, ‘features of activities’ and ‘organisational components’ – that were cited as facilitating a range of positive wellbeing outcomes, creating an environment that provides ‘physical and cognitive benefits’, ‘affirmation of identity’, ‘social connection’ and ‘benefits for care partners and others’. The wide-ranging benefits and enablers cited by participants within this research support the use of gardening groups as community-based interventions to reinforce positive psychological, physical and social outcomes for people with dementia. Themes also provide a clear framework for the design, implementation and evaluation of future gardening groups.
‘The boots will be on the coffin!’: multiple meanings of ageing for older people playing walking football
Authors: Thomas Gareth M. 
Published: April 2024

Abstract
A narrative of decline dominates the ageing process in the Global North. At the same time, older people have shared more positive stories of ageing, particularly with respect to their leisure practices. I explore this tension by drawing on an interview-based study with people playing walking football in the United Kingdom. My contention is that older people express multiple meanings of ageing that disturb deficit-focused cultural scripts of later-life, albeit in ways that can be fraught with tensions and contradictions. First, I explore how older people cultivate an alternate identity departing from assumptions of loneliness and degradation, with walking football providing an opportunity to develop friendships and a sense of belonging. Second, older people emphasise their own (good) health and the embodied demands of walking football, yet in doing so, can reinforce ageist discourses by distinguishing themselves from the inactive and isolated (older) other. Third, older people reflect on their current and future involvement in walking football in positive ways. However, through attending to the temporal character of their experiences, I show how, whilst older people express a desire to continue participation, this is threatened by the realities of their ageing bodies in ways that align with deficit framings of later-life. I conclude by calling for recognising the multiplicity of older people's experiences and exercising caution about reproducing over-simplistic and sweeping celebrations of ageing.
Assessing medical devices: a qualitative study from the validate perspective
Authors: Bloemen Bart , Oortwijn Wija 
Published: April 2024

Abstract

Objectives
Our objective was to explore procedures and methods used at health technology assessment (HTA) agencies for assessing medical devices and the underlying views of HTA practitioners about appropriate methodology to identify challenges in adopting new methodologies for assessing devices. We focused on the role of normative commitments of HTA practitioners in the adoption of new methods.

Methods
An online survey, including questions on procedures, scoping, and assessments of medical devices, was sent to members of the International Network of Agencies for Health Technology Assessment. Interviews were conducted with survey respondents and HTA practitioners involved in assessments of transcatheter aortic valve implantation to gain an in-depth understanding of choices made and views about assessing medical devices. Survey and interview questions were inspired by the “values in doing assessments of health technologies” approach towards HTA, which states that HTA addresses value-laden questions and information.

Results
The current practice of assessing medical devices at HTA agencies is predominantly based on procedures, methods, and epistemological principles developed for assessments of drugs. Both practical factors (available time, demands of decision-makers, existing legal frameworks, and HTA guidelines), as well as commitments of HTA practitioners to principles of evidence-based medicine, make the adoption of a new methodology difficult.

Conclusions
There is a broad recognition that assessments of medical devices may need changes in HTA methodology. In order to realize this, the HTA community may require both a discussion on the role, responsibility, and goals of HTA, and resulting changes in institutional context to adopt new methodologies.
