Communicating Corporate Social Responsibility in an Era of Disruption—A Study of Greek Companies Participating in Corporate Responsibility Index (CRI)
Authors: Xanthopoulou Panagiota , Kavoura Androniki , Sahinidis Alexandros , Antoniadis Ioannis 
Published: May 2024

AbstractGreek firms have begun to place a greater emphasis on CSR, and there is a shift away from financial gain and toward organizations showing respect for social issues pertaining to the environment in which they operate. This study looks at the social performance of all 27 firms that have taken part in the CR Index between 2008 and 2020 using the most recent information available about CRI operations in Greece from the time of the country’s economic depression to the present. The results imply that the companies under investigation adjusted to the economic climate by better allocating their CSR-related spending. Even though there was a general decline in the number of companies receiving lower-level distinctions, the companies included as a sample in this research demonstrated stronger CSR engagement, obtaining higher marks in their evaluation by the CRI. The fact that businesses have not adequately informed the public about their CSR efforts has implications for managers because they could do so. The study also adds to the body of literature by starting conversations around CSR communication.
How User Engagement Mediates the Effect of Social Media Marketing Efforts on Brand Loyalty of Green Products. The Role of Green Brand Bullying
Authors: Rizomyliotis Ioannis , Giovanis Apostolos , Konstantoulaki Kleopatra 
Published: May 2024

AbstractGreen products are getting more preferred than the conventional ones as they are related with sustainable consumption. Digital marketing practices are used by companies to reach the relevant target groups, to promote green products and develop sustainable relationships with their customers. Although there are several studies dealing with the role of social media marketing efforts, still, research in brand loyalty for green products has remained limited. The present study addresses this gap by proposing a conceptual framework describing the relationship between the social media marketing efforts that companies undertake to sell environmentally friendly products and brand loyalty by considering the intervening role of user engagement and green brand bulling. The theoretical analysis supports the view that there are significant nonlinear associations among these four constructs.
Artists and the University Heritage: The Case of the Athens University History Museum and the Exhibition “Opy Zouni: In First Person”
Authors: Papoulias Evangelos , Zounis Theoklis-Petros 
Published: May 2024

AbstractThe university museums protect, conserve and present the cultural heritage related to education. The paper presents the initiative of the Athens University History Museum of the National and Kapodistrian University of Athens (NKUA), a university museum that organizes for the first time in a university space a temporary exhibition dedicated to Opy Zouni, a painter with international recognition in the contemporary art of geometric abstraction. The exhibition “Opy Zouni: in first person” presented selected works by Opy Zouni with the main purpose of attributing the artistic dimension of the creator through the interpretation and analysis of her works by herself in the first person. The idea was conceived on the occasion of the tenth anniversary of the loss of the internationally renowned painter Opy Zouni with the consent of the family for a cultural event that would give the public a different perspective of her work. The paper presents a good example (useful for art curators and art managers) of a temporary exhibition of a university museum which connecting the contemporary art with the university heritage.

Authors: Ferrer Tenorio Jorge , Maldonado Castillo Idalia , Guzmán Flores Jessie Paulina 
Published: May 2024

AbstractDigital marketing studies, artificial intelligence and tourism make a theoretical and practical contribution to the applied customer journey model. This model examines the influence on the purchase decision in the virtual context, where traveler’s share their experiences through reviews, interact with other customers and potential customers. This allows the tourist to examine, evaluate, buy, recommend, and build brand loyalty. In this work qualitative research was conducted, with the intention of evaluating the feasibility of using twitter information to design a progressive web application. The functionality of the application considers identifying tourist sites in Querétaro on the map, integrating the reviews with an artificial intelligence model that catalogues the sentiments in a text using hashtags; and traces a route to facilitate the visit. Tourists can record the emotions experienced before, during and after the service provided to continue feeding information into the app. This allows companies to get real-time customer feedback, user preferences, as well as to evaluate and compare their services with those of competitors.
About water
Authors: Rapp Christoph 
Published: May 2024

AbstractChapter 1 is a teaser on water that intends to motivate the reader to concern oneself with this precious element and hydraulics particularly. Water’s impact on the development of civilization, the discovery of its chemical components, its occurrence on our planet as well as its origin are discussed. Yet another item is water’s life enabling quality in the context of its physical properties. Water as the resource for various industrial processes brackets its importance to us. Therefore, water has played an important role on human life ever since and thus spiritual dedication at least in the major religious groups.
Steady pipe flow
Authors: Rapp Christoph 
Published: May 2024

AbstractChapter 11 is dedicated to steady pipe flow; however, the derivation of the Prandtl-Colebrook equations has been shifted to the Appendix. Hydraulic losses are considered for both, laminar and turbulent flow and the friction coefficient introduced into the energy equation, which is consequently depicted through energy diagrams. Minor losses, pumps and turbines are considered as local impacts and pipe junctions round up this important topic that is also accompanied by codes, experiments, and examples.
Steady free surface flow
Authors: Rapp Christoph 
Published: May 2024

AbstractSteady free surface flow is Chapter 13’s topic which starts with the consideration of sub- and supercritical flow. From the Bernoulli equation for free surfaces, we make our way to the consideration of flows under sluice gates or over weirs, through syphon weirs or Venturi channels. Subsequently steady-state, uniform conditions and the describing equations are elaborated before nonuniform conditions are discussed. The chapter ends with the direct step method, for which, again, open-source codes are provided. At the end of the chapter the reader can solve problems of nonuniform free surface flows.

Abstract
Aims/hypothesis
Delivery by Caesarean section continues to rise globally and has been associated with the risk of developing type 1 diabetes and the rate of progression from pre-symptomatic stage 1 or 2 type 1 diabetes to symptomatic stage 3 disease. The aim of this study was to examine the association between Caesarean delivery and progression to stage 3 type 1 diabetes in children with pre-symptomatic early-stage type 1 diabetes.

Methods
Caesarean section was examined in 8135 children from the TEDDY study who had an increased genetic risk for type 1 diabetes and were followed from birth for the development of islet autoantibodies and type 1 diabetes.

Results
The likelihood of delivery by Caesarean section was higher in children born to mothers with type 1 diabetes (adjusted OR 4.61, 95% CI 3.60, 5.90, p<0.0001), in non-singleton births (adjusted OR 4.35, 95% CI 3.21, 5.88, p<0.0001), in premature births (adjusted OR 1.91, 95% CI 1.53, 2.39, p<0.0001), in children born in the USA (adjusted OR 2.71, 95% CI 2.43, 3.02, p<0.0001) and in children born to older mothers (age group >28–33 years: adjusted OR 1.19, 95% CI 1.04, 1.35, p=0.01; age group >33 years: adjusted OR 1.80, 95% CI 1.58, 2.06, p<0.0001). Caesarean section was not associated with an increased risk of developing pre-symptomatic early-stage type 1 diabetes (risk by age 10 years 5.7% [95% CI 4.6%, 6.7%] for Caesarean delivery vs 6.6% [95% CI 6.0%, 7.3%] for vaginal delivery, p=0.07). Delivery by Caesarean section was associated with a modestly increased rate of progression to stage 3 type 1 diabetes in children who had developed multiple islet autoantibody-positive pre-symptomatic early-stage type 1 diabetes (adjusted HR 1.36, 95% CI 1.03, 1.79, p=0.02). No interaction was observed between Caesarean section and non-HLA SNPs conferring susceptibility for type 1 diabetes.

Conclusions/interpretation
Caesarean section increased the rate of progression to stage 3 type 1 diabetes in children with pre-symptomatic early-stage type 1 diabetes.

Abstract
Purpose
To examine the differences in mental health problems by sexual orientation and gender identity in first-year university students in Chile during the pandemic. Methods: 7,213 first-year students aged 18 years and older from five universities participated as part of the World Mental Health - International College Student initiative in Chile. Students completed an online self-report survey between 2020 and 2021 that included measures of lifetime and 12-month major depressive episode, generalized anxiety disorder, panic disorder, bipolar disorder, drug abuse/dependence, alcohol dependence, non-suicidal self-injuries, and suicidal risk. Prevalence of mental health problems were estimated and the differences by sexual orientation and gender identity were examined using logistic and multinomial logistic regression models. Results: Between 84.1% and 98% of lesbian, gay, bisexual, trans, and other sexual and gender minority (LGBT+) students screened positive for at least one lifetime mental health problem and between 67.6% and 90.6% for two or more problems. For most outcomes, non-heterosexual (Odds Ratio [OR] between 1.25 and 7.00) and trans and gender nonconforming students (OR between 1.72 and 5.81) had significantly higher odds of positive screening for lifetime mental health problems than heterosexual and cisgender students, respectively. Similar results were observed for 12-month mental health problems. Conclusion: The results show differences in the prevalence of mental health problems in LGBT+ university students in Chile, which are consistent with those found in other countries. These results may be useful for planning interventions to improve the mental health of LGBT+ students.

Effect of imine-containing phenolic hardeners with different chain lengths and epoxy functionalities on thermal, mechanical, and healing properties of bio-based epoxy vitrimers
Authors: Kubota Ryuki , Sugane Kaito , Shibata Mitsuhiro 
Published: May 2024

AbstractMixtures of polyglycerol polyglycidyl ether (PGPE) and poly(ethylene glycol) diglycidyl ether (PEGDGE) with different molar ratios were cured with imine-containing phenolic hardeners prepared by the reactions of vanillin with ethylene glycol bis(3-aminopropyl) ether, diethylene glycol bis(3-aminopropyl) ether, and a polyetheramine (JEFFAMINE® ED-600) to produce bio-based epoxy cured products. Fourier-transform infrared spectroscopy (FT-IR) of the cured products revealed that the curing reaction of the epoxy and phenolic hydroxy groups was almost complete. The cross-linking density, glass transition temperature, and mechanical strength of the cured products decreased with decreasing the PGPE/PEGDGE ratio and increasing the oligoalkyleneoxy chain length of the phenolic hardeners. All cured products were healed three times at 100 °C under 2 MPa for 2 h. The healing efficiency, in terms of tensile strength, increased with decreasing PGPE/PEGDGE ratio and increasing oligoalkyleneoxy chain length. The polyetheramine-based cured product with the lowest PGPE/PEGDGE ratio exhibited the highest healing efficiency (94–97%), which only slightly decreased following repeated healing treatments.
Season, size, and sex: factors influencing monogenean prevalence and intensity on Gambusia affinis in New Zealand
Authors: Renner Ethan D. , Duggan Ian C. 
Published: May 2024

AbstractA number of studies have been conducted on monogenean seasonality, though primarily in continental regions with wide annual temperatures ranges. We investigated seasonal changes in the prevalence and intensity of Salsuginus seculus infesting sexually dimorphic western mosquitofish (Gambusia affinis) in New Zealand. This represents the first examination of seasonality for this species globally, and the first seasonal assessment of any monogenean population in New Zealand, a temperate country with a mild oceanic climate. Prevalence and intensity of S. seculus with respect to fish size and sex was also examined. Prevalence of S. seculus changed temporally, peaking in summer, and was strongly positively correlated with algal concentrations. This relationship may be associated with increasing food levels, leading to an increase in fish courting and mating, resulting in high numbers and close physical associations of G. affinis individuals, facilitating transmission of the monogeneans. Thus, biotic factors may be important in determining temporal changes in S. seculus prevalence in New Zealand. Female G. affinis had a significantly higher prevalence and mean intensity of S. seculus than males. Longer fish had a higher mean intensity and prevalence of S. seculus. Female G. affinis likely host disproportionately more monogeneans as they are larger than males. Alternatively, females may have a compromised immune response during reproductive periods. Overall, seasonal change was observed in S. seculus prevalence and intensity under New Zealand’s mild climatic conditions, and the larger female G. affinis in this dimorphic species supported a greater prevalence and intensity of infestation than males.

AbstractThe unmet need for mental health care is a global concern. There is a lack of cross-cultural studies examining adolescent help-seeking behavior from both formal and informal sources, including both high-and lower-income countries. This study investigates mental health help-seeking behavior in eight Asian and European countries. Data from 13,184 adolescents aged 13–15 (51% girls) was analysed using mixed-effects logistic regression with school-wise random intercepts to compare countries and genders. Although a significant proportion of adolescents considered getting or sought informal help, formal help-seeking remained exceptionally low, especially in middle-income countries (< 1%), while it ranged from 2 to 7% in high-income countries. Among adolescents with high emotional and behavioral problems (scoring above the 90th percentile on the Strengths and Difficulties Questionnaire), 1–2% of those in middle-income countries and 6–25% of those in high-income countries sought formal help. Girls generally seek more help than boys. The study shows the most adolescents do not receive formal help for mental health problems. The unmet need gap is enormous, especially in lower-income countries. Informal sources of support, including relatives, peers, and teachers, play a crucial role, especially in lower-income countries.
A Generalized Formulation for Group Selection via ADMM
Authors: Ke Chengyu , Shin Sunyoung , Lou Yifei , Ahn Miju 
Published: May 2024

AbstractThis paper studies a statistical learning model where the model coefficients have a pre-determined non-overlapping group sparsity structure. We consider a combination of a loss function and a regularizer to recover the desired group sparsity patterns, which can embrace many existing works. We analyze directional stationary solutions of the proposed formulation, obtaining a sufficient condition for a directional stationary solution to achieve optimality and establishing a bound of the distance from the solution to a reference point. We develop an efficient algorithm that adopts an alternating direction method of multiplier (ADMM), showing that the iterates converge to a directional stationary solution under certain conditions. In the numerical experiment, we implement the algorithm for generalized linear models with convex and nonconvex group regularizers to evaluate the model performance on various data types, noise levels, and sparsity settings.
The somatotroph pituitary gland function in high-aged multimorbid hospitalized patients with IGF-I deficiency
Authors: Tausendfreund Olivia , Bidlingmaier Martin , Martini Sebastian , Reif Hannah , Rippl Michaela , Schilbach Katharina , Schmidmaier Ralf , Drey Michael 
Published: May 2024

Abstract
Purpose
It is unclear whether the age-related decline in the somatotropic axis stems from a reduced growth hormone (GH) production in the pituitary gland, or from a peripheral origin akin to an acquired GH resistance. With the help of a GHRH/arginine test, high-aged multimorbid hospitalized patients with IGF-I deficiency are to be tested to determine whether there is primarily a pituitary GH deficiency in the sense of a somatopause.

Methods
Seventeen multimorbid patients (eleven men and six women) with a mean age of 82 years, with IGF-I concentrations below two standard deviations of 30-year-old men and women were identified. Patients suffered from a variety of common age-related stable diseases including coronary artery disease, chronic liver or kidney disease, chronic heart failure as well as acute conditions e.g., urosepsis or endocarditis. To assess the somatotropic axis they underwent a GHRH/arginine test. Results were evaluated using descriptive statistics.

Results
In average, the peak concentration of GH after stimulation was 14.8 µg/L with a range from 2.76 to 47.4 µg/L. Taking into account both, gender and BMI (with a mean of 26.5 kg/m²) for each participant, the pituitary gland was adequately stimulated in 16 out of the 17 patients. No patient reported common side effects related to the GHRH/arginine test.

Conclusion
The somatotroph pituitary gland retains its secretory capacity in the advanced aged. Therefore, age does not seem to be the driving pacemaker for the functional decline of the somatotropic axis within the aged population.
Consciousness and Perspectival De Se content
Authors: Sebastián Miguel Ángel 
Published: May 2024

AbstractMost people think indexical thought has special content (de se content). However, it has been acknowledged that classical examples, such as those offered by Perry and Lewis, are insufficient to establish this conclusion. Ongoing discussions typically focus on first-person beliefs and their relationship to the explanation of successful behavior and linguistic practices. Instead, I want to direct attention to the phenomenal content of our conscious experiences and the largely neglected contribution that its comprehension can make to the way in which first-person representation is understood. This paper offers a novel argument for both the existence and a specific interpretation of the essential indexicality thesis based on widely accepted assumptions regarding the relation between phenomenology and representation. Specifically, I will argue that if (i) two different individuals can have token experiences with the same phenomenology and ii) two token experiences of ordinary subjects with the same phenomenology have the same phenomenal content, then phenomenal content is de se content of a particular kind: perspectival de se content.

AbstractDirect regeneration method has been widely concerned by researchers in the field of battery recycling because of its advantages of in situ regeneration, short process and less pollutant emission. In this review, we firstly analyze the primary causes for the failure of three representative battery cathodes (lithium iron phosphate, layered lithium transition metal oxide and lithium cobalt oxide), targeting at illustrating their underlying regeneration mechanism and applicability. Efficient stripping of material from the collector to obtain pure cathode material has become a first challenge in recycling, for which we report several pretreatment methods currently available for subsequent regeneration processes. We review and discuss emphatically the research progress of five direct regeneration methods, including solid-state sintering, hydrothermal, eutectic molten salt, electrochemical and chemical lithiation methods. Finally, the application of direct regeneration technology in production practice is introduced, the problems exposed at the early stage of the industrialization of direct regeneration technology are revealed, and the prospect of future large-scale commercial production is proposed. It is hoped that this review will give readers a comprehensive and basic understanding of direct regeneration methods for used lithium-ion batteries and promote the industrial application of direct regeneration technology.
