The 2024 Presidential Election Through Latino Lenses: Priorities and Vote Choice
Authors: Garcia-Rios Sergio I. , Gutierrez Angela E. , Ocampo Angela X. , Ocampo-Roland Angie N. 
Published: February 2025

Abstract
This paper examines the Latino vote in the 2024 U.S. Presidential election. We examine the factors that were most important for Latino voters and investigate how these shaped their candidate choice. Specifically, we argue that it is important to explore the demographic heterogeneity within the Latino category, as well as to explore the various issues that different subsets of the group prioritize. In doing so, we focus on differences by gender and socioeconomic status and explore how those impacted vote choice in the 2024 election. We rely on data from Texas and nationwide to examine these differences. We find that Latino men were more likely to vote for Trump compared to women. Similarly, we explore the role of issue prioritization, finding that Latinos who prioritize various economic issues and immigration were more likely to vote for Trump. On the other hand, Latinos who prioritize abortion were more likely to vote for Harris. We also find notable differences in how issue prioritization worked distinctively for women, men and those with and without a college degree. This paper underscores that Latinos are not an ideologically cohesive group and that the label of “Latino” should not operate to homogenize the group’s multifaceted interests. Instead, it gives us a better understanding of which specific issues were salient for different segments of the Latino community in 2024, and how these worked in particular ways to drive presidential candidate choice.
Energy drinks, depression, insomnia, and stress in palestinian adolescents: a cross-sectional study
Authors: Maraqa Beesan , Fasfoos Ahmad , Alami Mohammad , Banat Nader , Amr Obada , Saraheen Atef 
Published: February 2025

Abstract

Objectives
Adolescents are increasingly consuming energy drinks (EDs), prompting worries about their potential mental health impacts. The association between ED use and psychological effects among Palestinian teenagers, particularly the impact of smoking habits such as waterpipes, electronic cigarettes, and cigarettes, is little studied. This study explores the correlation between ED consumption and mental health outcomes such as depression, insomnia, and stress among adolescents in Palestine.

Methods
A cross-sectional study was conducted from February to June 2024, involving adolescents aged 12–18 recruited from schools in the West Bank. Data collection utilized a structured questionnaire assessing ED consumption, smoking habits, depression (PHQ-9), insomnia (ISI), and stress (Adolescent Stress Scale). Data were analyzed using SPSS version 29.

Results
The research involved 1,668 adolescents, with a mean age of 15.67 years (±1.57 years). ED consumption was prevalent at 74.7 % (95 % CI: 76.5–72.7). Males and smokers, especially those using traditional cigarettes and waterpipes, exhibited a higher likelihood of consuming energy drinks (aPR: 2.18; 95 %CI: 1.64–2.91), (aPR: 2.99; 95 %CI: 1.49–5.59), and (aPR: 2.54; 95 %CI: 1.23–5.19). Depression exhibited a significant relationship with ED consumption (aPR: 2.25; 95%CI: 1.51–3.37). A dose-response relationship was identified between insomnia and ED consumption, with an adjusted prevalence ratio (aPR) of 2.42 (95 % CI: 1.56–3.47) for moderate severity and 2.95 (95 % CI: 1.28–6.75) for severe insomnia.

Conclusions
ED consumption is associated with poorer mental health outcomes, particularly among smokers. Interventions targeting both ED use and smoking behaviors are crucial to improving mental health in Palestinian adolescents. The study was conducted during the Gaza war, a period marked by heightened stress levels among participants due to increased security checks and economic hardships. These challenges may have influenced participants’ stress levels and impacted their purchasing behaviors for EDs and tobacco shisha products. Further research is needed to explore the long-term effects of these behaviors.
Varieties of Religious Naturalism: A Conceptual Investigation
Authors: Bishop John , Perszyk Ken 
Published: February 2025

Abstract
This paper explores the theme of religious naturalism, attempting to clarify different salient meanings for both component terms. We consider what forms of religious naturalism may recommend themselves as serious options for contemporary religious commitment. We argue that a viable robustly religious naturalist option may be built on the idea that the natural Universe has an overall purpose.
Immobilienfinanzierung durch Markt und Regulierung belastet
Authors: Just Tobias , Wiersma Simon 
Published: February 2025

Zusammenfassung
Die aktuellen Verwerfungen auf den deutschen Immobilienmärkten sind in erster Linie durch die Zinswende und die steigenden Baukosten begründet: nach über zehn Jahren positiver Preisentwicklung sind Transaktions- und Finanzierungsvolumina seit dem zweiten Quartal 2022 rückläufig. Banken reagieren vorsichtig, die Beleihungsquoten bleiben trotz sinkender Preise niedrig, der Fokus verschiebt sich auf vermietete Objekte in innerstädtischen Lagen. Ermutigend sind die bislang anhaltend niedrigen Ausfallquoten bei Immobiliendarlehen, v. a. im Vergleich zu der Zeit nach der Finanz- und Wirtschaftskrise 2007/2008. Dies gilt insbesondere für Wohnimmobilien, doch für Gewerbeimmobilien nur mit leichten Einschränkungen ebenfalls. Der Neubausektor ist jedoch massiv belastet, da viel Fremdkapital benötigt wird und sowohl von Banken ausgegebenes Fremdkapital als auch Mezzanine-Kapital nicht in ausreichendem Umfang und nicht zu darstellbaren Kosten zur Verfügung steht. Besserung ist kurzfristig nicht in Sicht. Es stellt sich angesichts dieses Marktumfeldes die Frage, ob jüngste Regulierungsmaßnahmen für eine weitere Verschärfung der Situation sorgen könnten. Zu nennen sind hierbei die Kapitalunterlegung von 150 % für Projektentwicklungen und die Einführung eines sektoralen Systemrisikopuffers für die Finanzierung von Wohnimmobilien in Höhe von 2 % ab dem 01. Februar 2023. Da der Immobilienmarkt seinen zyklischen Höhepunkt bereits überschritten hatte, werden diese Maßnahmen wohl nicht die primär beabsichtigte antizyklische, sondern eine prozyklische Wirkung entfalten.
Sorgende Gemeinschaften – leibhaftige Spiritualität
Authors: Coenen-Marx Cornelia 
Published: February 2025

Zusammenfassung
Wenn es darum geht, Verantwortungsnetze auf regionaler und lokaler Ebene neu zu beleben, sind „Caring Communities“ zum internationalen Leitbegriff geworden. Dabei meint Care mehr als Versorgung oder Behandlung; es geht darum, das Leben und die Lebenszusammenhänge in vulnerablen Situationen aufrechtzuerhalten. Die Caring Communities von heute sind Gemeinschaften auf Zeit; aber sie erinnern an die diakonischen Gemeinschaften des 19. Jahrhunderts. Sie verknüpfen informelle Netzwerke, die von Austauschprozessen leben, mit formalen Organisationen, für die bezahlte Dienstleistungen konstitutiv sind. Ziel ist, chronisch kranke und pflegebedürftige Menschen als gleichberechtigtes Gegenüber, als „Nächste“ wahrzunehmen – nicht nur als Versorgungsfälle. Es geht darum, dass sorgende Gemeinschaften entstehen, in denen jeder in seiner Einzigartigkeit geachtet wird und dass die Sorgekräfte aller Beteiligten gestärkt werden.

Abstract
Die Wirtschaft steht vor Herausforderungen, die nachhaltiges Wirtschaften erfordern. Die Automatisierung bietet hierbei großes Potenzial, indem sie Energieeffizienz, Ressourcenschonung und soziale Verbesserungen fördern kann. Dennoch stellen bestehende Nachhaltigkeitsbewertungsmethoden für Automatisierungslösungen spezifische Anforderungen oft unzureichend dar. Daher entwickelt das IPH eine Methode, die KMU bei der effektiven Implementierung nachhaltiger Automatisierungslösungen unterstützt.

Abstract
Getrieben durch Nachfrage und auch Regulierung, gewinnt Nachhaltigkeit in der Produktion zunehmend an Bedeutung. Der Beitrag zeigt anhand der UN-Nachhaltigkeitsziele (SDGs) auf, dass eine ganzheitliche Nachhaltigkeitsstrategie über den aktuellen Fokus der Ressourceneffizienz und die Anwendung bestehender Werkzeuge und Methoden hinausgeht. Eine frühzeitige und ganzheitliche Betrachtung erlaubt das Schöpfen von umfassenden Innovationspotenzialen und sichert einen langfristigen Wettbewerbsvorteil.
Optimal recovery of mappings based on linear information with the help of $T$-splines in Banach spaces
Authors: Babenko V.F. , Babenko Yu.V. , Parfinovych N.V. 
Published: February 2025

This work is dedicated to solving problems of optimal recovery of operator $A$ (not necessarily linear), defined on a subset $\mathfrak{M}$ of a Banach space $H$ using information about elements of the $\mathfrak{M}$, given by a linear bounded operator $T\colon H\to Y$ where $Y$ is some Banach space. We show that under certain condition the optimal method of recovery is given by abstract interpolation splines in $H$ generated by $T$ ($T$-interpolating splines).
Some properties of the Generalized Jacobi polynomial
Authors: Waghela D. , Rao S.B. 
Published: February 2025

An attempt is made to find recurrence relation and further properties of the generalized Jacobi polynomial $P_{n,\tau }^{\left( {\alpha ,\gamma ,\beta } \right)}(x)$ . Yet another generalization $P_{n,\tau ,\lambda }^{\left( {\alpha ,\gamma ,\beta } \right)}(x)$ of Jacobi polynomial $P_n^{\left( {\alpha ,\beta } \right)}(x)$ has been introduced and its properties have been studied. For $\lambda = \tau$ we recover $P_{n,\tau }^{\left( {\alpha ,\gamma ,\beta } \right)}(x)$. The results so obtained may be useful in the theory of special functions, where Jacobi polynomials occur naturally.

Published: February 2025

AbstractBackgroundMost problematic pornography use (PPU) research relies on cross-sectional designs. Ecological momentary assessment (EMA) studies are needed to better understand PPU correlates. We evaluated how daily PPU and pornography use ratings were correlated with baseline PPU, pornography use frequency (over 12-months), alcohol problems, and depression in a community sample of men living in the United States.DesignParticipants (n = 113, mean age 37.95 [11.09]) completed a baseline survey battery followed by daily EMAs over 14 days (k = 1,240 observations). Data were gathered on the Prolific panel.FindingsScreener thresholds suggested 32%, 25%, and 24% of sample were at-risk for PPU, depression, and alcohol use problems respectively. Baseline estimates suggested PPU to be weakly correlated with depression (r = 0.29) and past 12-month pornography use (r = 0.27), but not alcohol problems (r = 0.08). Multilevel modeling indicated aggregated pornography use amount as a robust correlate of aggregated pornography control problems over the observation period. Baseline PPU and pornography use indicators were significant predictors of aggregated control problems and pornography use amount respectively. Baseline depression and alcohol problem predictors were non-significant. Past 12-month pornography use frequency and depression scores exacerbated the relationships between daily pornography use amount and aggregated control problems. Sensitivity analyses specific to only those who used pornography across all observations were consistent with full model results (though effect strength changed).ConclusionsWith exception to the PPU and pornography use indicators, cross-sectional baseline estimates (e.g., alcohol problems and depression) were generally not predictive of aggregated pornography use and control problems in the following 14 days.

Aim of the studyThis provides insight into the current and future water situation in the East Nile Delta in Egypt. Additionally, the study aimed to identify gaps in knowledge that require further research and to illustrate the different types of models used to optimize water resources management and maintain food security.Material and methodsThe study analyzed the status of water resources availability, water demand, and other influencing factors in the East Nile Delta. To address water scarcity, the study employed optimization models, specifically using linear optimization programming. This model was applied to the Eastern Delta area, focusing on the region supplied by the Ismailia Canal. The model aimed to balance the limited supply of freshwater with the increasing demand by proposing changes in cropping patterns.Results and conclusionsThe study found that the best way to secure water supply and minimize water scarcity is by using optimization models. In the Eastern Delta, the area supplied by the Ismailia Canal had a water deficit of about 789.81 MCM. By changing the cropping patterns, the water deficit could be reduced. The results indicated a decrease in the cultivation of non-strategic crops such as onions, garlic, fruit trees, peanuts, sesame, and soybeans. Conversely, there was an increase in the cultivation of strategic crops such as wheat, cotton, maize, and corn, as well as crops with high net yields like tomatoes and potatoes. These changes would help balance water demand and supply, ensuring a more sustainable water management strategy for the future.

Public health enhancement system in Russia includes a number of main components, one of which is measures aimed at increasing the population’s health literacy, creating a healthy lifestyle civility and a responsible attitude to health. An important social group of influence are women. Women's health literacy enables them to participate in health promotion activities and engage their communities in healthy lifestyles at local public level.Aim. To study the health literacy level among "Woman — Health Model" project participants in the Yamalo-Nenets Autonomous Okrug.Material and methods. An online survey of "Woman — Health Model" project participants aged ≥18 years was conducted using a validated and adapted HLS19-RUS questionnaire, developed on the basis of international questionnaire of World Health Organization Network on Measuring Population and Organizational Health Literacy (M-POHL). Health literacy (HL) was studied by means of standardized indices for four HL levels as follows: low, problematic, sufficient, excellent. Frequency analysis and associations of HL with socio-demographic characteristics of Yamal women. Also, navigational HL of women was studied for the first time. Statistical data processing was carried out using SPSS 23.0 for Windows and MS Excel 2016 software.Results. Of the 2000 women participating in the Project, 1445 took part in the survey. The response rate was 72,25%. The results showed that 27,0% of participants had insufficient HL in disease prevention, assessment and use of health information. The most vulnerable groups were identified, which include women aged ≥65 years without higher education and job. Women participants in the Project from the YamaloNenets Autonomous Okrug encounter the greatest difficulties with regard to navigational HL (53,3%) — the ability to navigate services, changes, innovations and specialists of the healthcare system.Conclusion. The results obtained made it possible to further adapt the training program for Project participants taking into account the identified level of HL and the difficulties women face in regard to health information.

Published: February 2025

Aim. Based on the generalization of Russian and international experience, to formulate the main types and components of preventive counseling (PC) of patients with risk factors for noncommunicable diseases, analyze existing programs and initiatives aimed at developing PC methods and technologies, including new ones, with subsequent implementation in primary health care (PHC). To identify and structure the main problems and barriers of the implementation of individual PC technologies in practice.Material and methods. Systematic search and analysis of publications on the problem, systematization of the obtained information on the use of motivational, clinical and economic incentives for PC aimed at changing the population behavior on their own health.Results. The main options/types and forms of PC are defined. Examples of successful implementation of short PC and in-depth PC technologies in primary health care practice are given. The following problems and barriers hindering the implementation of in-depth PC in primary health care were identified: insufficient training of health workers regarding communication skills and methods of motivational counseling; limited time for consultations; insufficient motivation of the patients themselves to change their lifestyle and comply with recommendations; management barriers associated with limited resources, the level of digital maturity of the medical organization and support from the healthcare system for the implementation of multifactorial medical prevention technologies.Conclusion. The summarized factual data confirm the importance and necessity of introducing PC as an effective method for reducing modifiable risk factors for noncommunicable diseases. The most promising direction is in-depth PC, which, due to its targeted nature and comprehensive approach, allows achieving results in changing patients' behavior and reducing risk factors.

Aim. To study the effects of catheter renal denervation (RDN) on blood biomarker levels in patients with cardiovascular comorbidity and type 2 diabetes (T2D).Material and methods. Sixty patients with true resistant hypertension (HTN) in combination with T2D and coronary artery disease after complete myocardial revascularization using percutaneous coronary intervention were included in a prospective observational non-randomized study. Patients were distributed in a 1:1 ratio into the intervention group and the control group. RDN was performed through femoral access using a Spyral system (Medtronic, USA). The primary endpoint was the change in plasma renin activity after 12 months. The results are presented as Me (Q25; Q75).Results. In the intervention group, plasma renin activity significantly decreased from 4,65 (1,88; 7,79) to 2,21 (0,87; 5,49) ng/ml/h; angiotensin-I from 1,73 (0,34; 3,22) to 0,46 (0,31; 1,95) ng/ml; aldosterone from 131 (78; 173) to 118 (68; 153) pg/ml (p<0,05 for all). There were no significant changes in the control group. A decrease in office systolic and diastolic blood pressure was confirmed, with the greatest antihypertensive effect achieved in the high-renin hypertension group (renin activity at inclusion >6,5 ng/ml/h). The blood pressure decreases correlated with decrease in plasma renin activity (r=0,85; p<0,05). A significantly positive effect of RDN on reducing the levels of C-reactive protein, fasting glucose, glycated hemoglobin, and triglycerides was revealed (p<0,05 for all), without significant changes in the control group. The intervention and control groups did not statistically differ in the incidence of major adverse cardiovascular events, the glomerular filtration rate was comparable in both groups and did not change over time.Conclusion. The use of RDN in comorbid patients is safe and allows for better control of modifiable risk factors for the progression of HTN and T2D due to an improvement of blood pressure, carbohydrate metabolism parameters, regulatory factors of the renin-angiotensin-aldosterone system, and factors of the systemic inflammatory response.
