Material circularity and environmental quality in the EU: what causes what and where?
(IOP Publishing Ltd, TEMPLE CIRCUS, TEMPLE WAY, BRISTOL BS1 6BE, ENGLAND, 2025) Alola, Andrew Adewale; Özkan, Oktay; Uzuner, Gizem
Although the green and blue dividends associated with circular economy have been widely advocated, whether circular economy necessarily guarantee environmental quality remains unclear. To provide a more precise insight, in this case for a novel case of all the European Union countries, environmental effect of the share of used material resources from the reuse of waste materials is examined over the period 2010–2021. The results reveal that the reuse of waste materials statistically (i)increase CO2 emissions in most quantiles in Austria, Belgium, Denmark, France, Greece, Hungary, Lithuania, Malta, Netherlands, Poland, and Slovenia, (ii) mitigate CO2 emissions in most quantiles in Bulgaria, Croatia, Cyprus, Estonia, Finland, Italy, Portugal, Romania, Slovak Republic, Spain, and Ireland, and (iii) either increasing or reducing CO2 emissions depending on the quantile of material circularity use rate and CO2 emissions in Czech Republic, Germany, Luxembourg, Sweden, and Latvia. This result points to a more policy driven approach.
ChatGPT Usage Scale in Education: Validity and Reliability Study
(INT SOC TECHNOLOGY EDUCATION & SCIENCE-ISTES, 19723 LINDENMERE DR, MONUMENT, COLORADO 80132, UNITED STATES, 2025) Taktak, Mustafa; Bafralı, Görsev
This study aimed to develop a valid and reliable scale to measure individuals' and organizations' attitudes toward the use of ChatGPT, emphasizing the necessity for organizations to adapt to rapidly evolving information and technology environments. The methodology consisted of three stages. In the first stage, a 13- item draft scale was administered to 213 participants, and its construct validity was evaluated through Exploratory Factor Analysis (EFA). In the second stage, based on EFA results, the scale was reduced to 12 items and administered to 175 participants, followed by Confirmatory Factor Analysis (CFA) to validate its structure. In the third stage, test-retest reliability and criterion validity were examined with 67 school administrators and teachers. The analyses revealed that the scale consisted of two dimensions, "opportunities" and "challenges," and CFA confirmed this structure, with fit indices falling within acceptable ranges. The overall reliability coefficient (Cronbach's Alpha) was calculated as 0.71, and further analyses, including independent sample t-tests, item-total and item-residual correlations, inter-factor correlations, and test-retest correlations, supported the scale’s validity and reliability. Based on the findings, the scale was recommended to be named the "ChatGPT Usage Scale," offering a valuable tool for assessing attitudes toward ChatGPT use among individuals and organizations.
Is Ageing Related to Poverty? A Case Study in Turkish Older Population
(SOSYOEKONOMI SOC, ELIF SOKAK, 7-98 ZUBEYDE HANIM MAHALLESI, ISKITLER, ALTINDAG, ANKARA 06070, Turkiye, 2025) Sönmez, Seda; Akdeniz, Şengül; Tufan, İsmail; Özgür, Özlem; Ayan, Fatma Sıla; Faezi, Sanam Asadi
This study seeks answers to whether ageing is related to poverty or not in terms of sociodemographic variability in terms of Türkiye, a developing country. The study is based on 1,512 reference people randomly selected from seven provinces of Türkiye in October 2021-January 2022, and generalised, hierarchical, and logit log-linear model analyses were examined. It is determined that the age factor has the most decisive impact on poverty compared to the other variables. The genderbased poverty analysis results show that equality between women and men is close. The income levels of educated individuals younger than 65 are insufficient to meet living costs.
Thermal and Mechanical Analysis of Wheel Rim in Formula 1 Vehicles
(VINCA INST NUCLEAR SCI, MIHAJLA PETROVICA-ALASA 12-14 VINCA, 11037 BELGRADE. POB 522, BELGRADE 11001, SERBIA, 2025) Kepekçi, Haydar İzzettin; Ağca, Mehmet Erdem; Komatina, Mirko S.
The wheel rim is a metal or alloy component that holds the tire and connects it to the vehicle. The wheel rims of Formula 1 cars are exposed to thermal stresses during the race and frequent braking at high speeds. In addition to thermal resistance, wheel rims must possess high mechanical durability. Therefore, material selection is crucial, along with the designs of the wheel rims. In the production of wheel rims for Formula 1 vehicles, magnesium, aluminum, and carbon fiber wheel rims are commonly used. Each of these materials has its advantages and limitations. Optimization processes in Formula 1 technology aim to reduce mass while increasing mechanical and thermal properties. Therefore, alloys used in wheel rim production are continuously evolving. In this study, deformation, stress, and temperature values were investigated using the CF) method by exposing Mg AZ80, Al 6061-T6, and carbon fiber to conditions of 300 °C temperature, 1 MPa pressure, and 300 km/h speed. Turbulence modelling was carried out using the k-ε method in numerical analyses, which utilized a mesh file consisting of approximately 2 million grids. As a result, the highest deformation in mechanical pressure analyses was obtained using Mg AZ80 material. In contrast, carbon fiber achieved the lowest deformation value in the analysis. Regarding thermal results, the lowest temperature value of 282.75 °C was obtained from the wheel rim made of carbon fiber, whereas with the use of Mg AZ80 material, this value reached up to 292.03 °C. Considering these values, it was concluded that carbon fiber is the most suitable wheel rim material for Formula 1 race cars.
Evaluating the Repor aluating the Reporting and Saf ting and Safety Cultur ety Culture of an Airline e of an Airline According to Patankar and Sabin atankar and Sabin's Safety Cultur ety Culture Pyramid
(EMBRY-RIDDLE AERONAUTICAL UNIV, 600 SOUTH CLYDE MORRIS BLVD, DAYTONA BEACH, FLORIDA 32114-3900, 2025) Mumlu Karanfil, Seda
As a result of the literature review, it is seen that the safety management system in airline businesses is mostly evaluated with Reason's just culture model. The fact that there is no research examining Patankar and Sabin's (2010) safety culture pyramid on airline operations, except for a study conducted in the field of ground handling services (Poçar, Işık, & Durmaz, 2022), constitutes the importance and unique value of the research. As stated by Poçar et al. (2022), Patankar and Sabin's (2010) safety culture pyramid is not sufficiently included in practice, and this model is important in terms of drawing attention to the impact of employees' safe behaviors on safety culture. In this direction, the SMS instructions, reporting policies and SMS reports of the airline subject to the research were obtained as documents and analyzed. As another stage of the research, it was aimed to evaluate the SMS reports of the airline according to Patankar and Sabin's safety culture pyramid. With this evaluation, content analysis was conducted to determine the step of the airline in the safety pyramid. Unlike previous studies, this study is thought to contribute to the literature by explaining the relationship between reporting culture, safety culture and safety management system and evaluating the reporting in the organization according to Patankar and Sabin's safety culture pyramid.

Furthermore, we scrutinize the property of closure under convolution operations for this subclass.
The Effectiveness of Bladder Filling Technique for Preventing Intraoperative Bladder Injury in Pregnant Women Undergoing Placenta Accreta Surgery: A Systematic Review
(SAGE PUBLICATIONS INC, 2455 TELLER RD, THOUSAND OAKS, CA 91320, 2025) Fashafsheh, Nawras; Elhaty, İsmail A. M.
Background: Placenta accreta spectrum (PAS) disorders have become more noticeable as a serious and potentially life-threatening obstetric concern due to a rise in prevalence from 0.12% to 0.31% in recent years. New preventive measures, such as the bladder filling technique, seek to identify the bladder’s borders, protect it, and displace it away from the lower uterine segment during placental removal. Aim: To determine whether the saline bladder filling technique prevents the incidence rate of intraoperative bladder injuries among pregnant women undergoing PAS surgery. Method: Systematic searches were conducted in PubMed, Embase, and the Cumulative Index to Nursing, Allied Health Literature and, Google Scholar from 2013 to 2023. The Cochrane Risk of Bias (ROB 2.0) and ROB in Nonrandomized Studies of Interventions tools were used to assess the quality of the selected studies Findings: A total of 2,094 articles were initially retrieved, and after screening, four articles met the eligibility criteria and were included in the final. The primary outcome of this systematic literature review (SLR) indicates that the utilization of the bladder filling technique was associated with a reduced occurrence of bladder injury, with an incidence range of 4.5% to 21.9% when the bladder filling technique utilized, in contrast to an incidence range of 13.1% to 32.4% when the bladder-filling technique was not utilized. Furthermore, the utilization of the bladder filling technique was found to be correlated with a reduced surgical procedure time and decreased blood loss. Conclusion: This SLR reveals that utilizing the bladder filling technique during PAS surgeries decreases the occurrence of intraoperative bladder injury, which, in turn, reduces the occurrence of other intraoperative complications, including intraoperative blood loss. Therefore, healthcare providers and policymakers should start developing surgical protocols for the use of this technique, as it has the potential to significantly impact the outcomes of pregnant women undergoing PAS surgeries.
Kerem and Aslı as An Eastern Narrative and Melodramatic Turkish Cinema
(Rector CIU Cyprus Int Univ-, Nicosia -, Turkiye, 2025) Doğan, Emre
The Eastern narrative tradition represents an output of the world of Eastern cultural mentality. Oral, open-form, interactive, replete with superficial contrasts and tenuous constructed rational cause-and-effect relationships, Eastern works are considered technically flawed, yet creative in content. These characteristics of the Eastern narrative are similar to those of the cinematic melodrama genre. Melodrama, one of the most performed genres of Turkish cinema, conveys moral messages, superficially reiterates various patterns/clichés, appeals to emotions and employs contrasts, and frequently includes elements such as coincidence and surprise, with a narrative that is largely devoid of cause-andeffect relationships. In this study, I tried to analyze the relationship between Eastern narrative and Turkish melodrama through the story of Kerem and Aslı, and the film (1971). The conclusion I reached is that the formal and contextual elements of the Eastern narratives have commonalities Turkish melodramas. I believe that this is because the mentality of the Eastern cultural circle feeds from the same source or has similarities with the traditional mentality that constructs melodrama. In the study, I suggest that this similarity should be considered as an opportunity for creativity. In the study, I used the descriptive method and genre film criticism.
Investigation Of Gst And Drug Resistance Protein Expressions in Relation To Chemotherapy in Breast Cancer
(John Paul II Univ Biala Podlaska, Sidorska 95/97, Biala Podlaska 21-500, POLAND, 2025) Koçdoğan, Arzu Kaya; Kılıç, Murat; Oğuztüzün, Serpil; Benzer, Emine; Dilek, Gülay; Kahraman, Yavuz Selim; Gülçelik, Mehmet Ali
Background. During cancer therapy, resistance to chemotherapeutic agents is common and often linked to multidrug resistance mechanisms. Glutathione S-transferases (GSTs) and ATP-binding cassette (ABC) transporters, including multidrug resistance (MDR) proteins, multidrug resistance-associated proteins (MRPs), and breast cancer resistance protein (BCRP), are implicated in drug resistance. Material and methods. Protein expressions were determined in the tumor and surrounding tumor free breast tissues of 145 breast cancer patients by immunohistochemistry technique. Among 145 patients, 50 received preoperative (neoadjuvant) chemotherapy, and 95 received postoperative (adjuvant) chemotherapy. Results. In 50 neoadjuvant breast cancer patients, GSTA1, GSTK1, GSTM1, GSTO1, GSTP1, GSTS1, GSTT1, GSTZ1, MDR1, MRP1, MRP2, MRP3, MRP7, and BCRP expressions were higher in tumor epithelium compared to normal epithelium (p<0.05). In 95 adjuvant breast cancer patients, GSTA1, GSTK1, GSTM1, GSTP1, GSTT1, GSTZ1, MDR1, MRP1, MRP2, and MRP3 expressions were higher in tumor epithelium than in normal epithelium (p<0.05). GSTP1, GSTT1, and MRP3 expressions were significantly higher in neoadjuvant compared to adjuvant-treated breast cancer patients’ tumor tissues (p<0.05). Conclusions. GSTP1, GSTT1, and MRP3 may be important in inactivating the chemotherapeutic agents used in platinum-based treatment and are thus responsible for the drug resistance in breast cancer patients.
The Russian-Ukraine War and the Uses of Naval Mines in the Black Sea: The Legal Consequences in Turkey
(ISTANBUL UNIV, FAC POLITICAL SCIENCES, ISTANBUL 00000, Turkiye, 2025) Diop, Mouhamed Bachir
Stray mines in the Black Sea (BS) have sparked substantial debates. Despite the various areas of concern, this matter also warrants a legal perspective. Given that Russia, Turkey, and Ukraine are the primary countries significantly involved, each has developed a distinct legal personality under international law. Therefore, it is important to refer to international law to elucidate this complex issue. This study examines the legal intricacies of the stray mine situation in the BS region by focusing on legal aspects. It also considers other relevant factors, particularly the potential legal implications for Turkey. In the context of this study, we argue that Turkey's geopolitical position, along with its international commitments, places it in a significant role and brings it into close engagement with other nations, especially amid the Russian-Ukrainian conflict. In this study, I will discuss the general framework of international law governing the use of naval mines in international conflicts, particularly in the event of war between Russia and Ukraine. Despite the existence of international customs, several international agreements, including the International Montreux Convention concerning the Strait of Istanbul, play a substantial role in this issue.

(TERMEDIA PUBLISHING HOUSE LTDKLEEBERGA 2, POZNAN 61-615, POLAND, 2025) Yılmaz, Fatma Betül; Satıcı, Seydi Ahmet; Okur, Sinan; Kütük, Hasan; Aktepe, Zahide Gül
background On February 6, 2023, a devastating earthquake disaster occurred in Türkiye, affecting millions. Mental health concerns were high due to people’s exposure to loss and possible earthquakes. In these times, variables that predict individuals’ mental health should be determined. The aim of this study was to investigate the relationship between intolerance of uncertainty, curiosity, generalized anxiety disorder, and subjective happiness using structural equation modeling. participants and procedure The research was conducted on Turkish individuals in 29 different cities in Türkiye. For the purpose of the research, data were collected from 345 participants (79.7% females, 20.3% males, age range = 18-61, Mage = 26.73 years). One hundred eighty nine of the participants were single (54.7%), 77 were married (22.4%), and the remaining 79 were in a relationship or engaged (22.9%). Additionally, it was found that 52 of the participants were parents (15.1%). In terms of socio-economic status, the majority fell into the middle-class category (n = 263, 76.2%). results It was found that intolerance to uncertainty predicted subjective happiness, and generalized anxiety disorder mediated this relationship. In addition, curiosity predicted subjective happiness, and generalized anxiety disorder mediated this relationship. conclusions All the findings obtained in the research revealed the mental health problems experienced by individuals after the earthquake. This research on earthquakes and mental health makes important contributions to the field of psychology.
The cruciality of environmental degradation, energy use and urbanization to policy framework for sustainable growth and development: evidence from Spain
(EMERALD GROUP PUBLISHING LTD, Floor 5, Northspring 21-23 Wellington Street, Leeds, W YORKSHIRE LS1 4DL, ENGLAND, 2025) Bekun, Festus Victor; Adebayo, Tomiwa Sunday; Agboola, Mary; Onifade, Stephen Taiwo; Awosusi, Abraham Ayobamiji
Purpose – Attaining a sustainable environment has become an international commitment. Therefore, mitigating climate change concerns is pertinent for a sustainable ecosystem. This study aims to focus on the Spanish economy, which has enjoyed some positive growth trends over the years. However, there remains an unaddressed puzzle as to whether the experienced growth path is green or dirty given the wake of global connectedness. These concerns are related to the objective of the sustainable development goals (SDGs) that comprises economic growth (SDGs-8), climate issues (SDGs-13) and responsible energy consumption and access to energy (SDGs-7, 12). Design/methodology/approach – This research empirically explores the comovement and coherence between CO2 emissions and its driving factors – specifically renewable energy, fossil fuel consumption, urbanization and economic growth using the wavelet tools. Findings – The result of the wavelet coherence shows that (i) renewable energy and CO2 emissions are out-phase; (ii) economic growth and CO2 are in-phase; urbanization and CO2 are in-phase; and (iv) fossil fuel and CO2 are in-phase. The result of the multiple wavelet coherence shows that CO2 in Spain were strongly linked to urbanization, economic growth and energy consumption. While coherence with renewable energy and urbanization weakened after 2000, fossil fuel reliance remained a key driver. Practical implications – These results are not desirable for the case study (Spain). Therefore, there is a necessity for a gradual and more aggressive shift in the Spanish energy mix to renewables. The shift to renewables is required for inclusive growth and a green growth path in Spain. Originality/value – In this study, the authors used wavelet tools, which help uncover hidden information across different time-frequency domains. The importance of the ramifications of this research will also go beyond a localized relevance to the Spanish economy alone, as there is relative applicability of some of the practical implications from the study to other similar European Union (EU) countries considering Spain’s stance in the EU in terms of geography, economics and politics.
Cytotoxic and anti-migratory effects of polyphenolic compounds on breast cancer cells by altering Jam-A, LFA-1, and VLA-4 gene expression
(TAYLOR & FRANCIS LTD, 2-4 PARK SQUARE, MILTON PARK, ABINGDON OR14 4RN, OXON, ENGLAND, 2025) Özkara, Gülçin; Ceviz, Ayşe Begüm; Eronat, Allison Pinar; Pehlevan Karabıyık, Funda; Candan, Gonca; Öztürk, Oğuz; Yılmaz Aydoğan, Hülya
This study represents the initial research of the effects of a combination of the largest number (13) of different polyphenic substances (PFK5120), formulated based on the propolis content on cell viability, migration and expression of lymphocyte function-associated antigen-1 (LFA-1), very late antigen-4 (VLA-4) and junction adhesion molecule A (Jam-A) in breast cancer (BC) cells. PFK5120 negatively affected cell viability at a 5% concentration as compared with unexposed ones (p<0.001). Treatment with 20% PFK5120 for 48h down-regulated Jam-A in MCF-7 and MCF-10A, up-regulated LFA-1 in MCF-10A and MDA-MB-231, and down-regulated VLA-4 in MCF-10A and MDA-MB-231 (p<0.001). Furthermore, migration was found to be inhibited by PFK5120 at varying doses and times. Migration was completely inhibited by 35% PFK5120 treatment in MDA-MB-231, while even lower concentrations (10%) were effective in MCF-7. Current findings indicate that PFK5120 represents a valuable natural component of BC therapy through its cytotoxic and anti-migratory effects.

(ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD, 2-4 PARK SQUARE, MILTON PARK, ABINGDON OX14 4RN, OXON, ENGLAND, 2025) Tanrıverdi, Haluk; Çıkı, Kartal Doğukan; Öğretmenoğlu, Mert; Uygun, Nursaç
This research investigates the experiential dimensions of cave tourism by analysing visitor experiences through user-generated content. A qualitative case study approach was adopted, utilising TripAdvisor reviews as the primary data source due to its relevance and widespread use in tourism research. Visitor comments were collected over a 20-day period between late July and early August 2024, covering reviews from 2019 to 2024. The findings reveal that cave tourism experiences encompass five key dimensions: educational, aesthetic, escapism, entertainment, and perceived benefits (e.g. health benefits and social interaction). The originality of this research lies in its exploration of the multifaceted experiences of cave visitors, highlighting the significance of aesthetic, entertainment, educational, and escapist elements, along with perceived benefits such as health and social interaction, in shaping the overall visitor experience. The findings contribute to the literature by offering empirical insights that inform strategic recommendations for the sustainable development of cave tourism. In this regard, the research proposes actionable suggestions to enhance service quality and promote visitor satisfaction in cave tourism settings.
Exploration of the soliton solutions of the (n+1) dimensional generalized Kadomstev Petviashvili equation using an innovative approach
(NATURE PORTFOLIO, HEIDELBERGER PLATZ 3, BERLIN 14197, GERMANY, 2025) Kopçasız, Bahadır; Sağlam, Fatma Nur Kaya; Bulut, Hasan; Radwan, Taha
In this paper, we deal with the (n+1)-dimensional generalized Kadomtsev-Petviashvili equation (dgKPE). This is an important model in nonlinear science, with applications in various fields. Its integrability and rich soliton dynamics continue to attract researchers interested in the field of nonlinear partial differential equations (NLPDEs). We are interested in the new auxiliary equation method (NAEM). We reduce the equation to an ordinary differential equation (ODE) with the help of an appropriate wave transformation and search for different types of soliton solutions. Additionally, we demonstrated the efficacy of the NAEM as a straightforward yet powerful mathematical instrument for handling challenging issues, highlighting its potential to resolve the challenging problems related to the study of nonlinear equations. This technique yields several types of solutions for (n+1)-dgKPE, including trigonometric, hyperbolic, shock wave, singular soliton, exponential, and rational functions. A range of graphs showcasing the results are reviewed, as well as the wave behavior for the solutions in different circumstances. The obtained data provide important information for studying hydrodynamic waves, plasma fluctuations, and optical solitons. They also aid in understanding the behavior of the KPE in different physical situations. We clarify in this article how the (n+1)-dgKPE, when combined with NAEM, can result in better data transmission rates, optimized optical systems, and the advancement of nonlinear optics toward more dependable and efficient communication technologies. The obtained information clarifies the equation and opens up new avenues for investigation. To our knowledge, for this equation, these methods of investigation have not been utilized before. The accuracy of each solution has been verified using the Maple software program.
Effects of Blood Flow Restriction Resistance Exercise Versus Traditional Resistance Exercise in Voluntary Exhaustion on Quadriceps Muscle Adaptations in Untrained Young Males: A Randomized Trial
(MDPI, MDPI AG, Grosspeteranlage 5, CH-4052 BASEL, SWITZERLAND, 2025) Akgül, Mustafa Şakir; Uysal, Hüseyin Şahin; Keskin, Nevin Köremezli; Çetin, Tuğba; Başdemirci, Merve; Akgül, Melike Nur; Yıldız, Zehra; Çiftçi, Ebubekir; Soslu, Recep
Background and Objectives: This study compared the effects of blood flow restriction resistance exercise (BFR-RE) and high-load resistance exercise (HL-RE) in voluntary exhaustion on quadriceps muscle adaptations in untrained young males. Materials and Methods: This study used a randomized controlled design that included 30 untrained young males (age = 21.42 ± 2.51). The BFR-RE group performed leg extension exercises with 60% occlusion pressure and 30% of one maximum repetition in volitional exhaustion. The same exercise was conducted at 70% 1RM in the HL-RE group. Fourteen variables were used to evaluate the intervention efficacy, including muscle thickness, stiffness, strength, cross-sectional area (CSA), and subcutaneous fat thickness. Analyses were reported using frequentist and Bayesian approaches. The Bayes factor (BF10 and BFincl) was interpreted based on negative and positive values. Results: The results revealed that the main effect of time was statistically significant for muscle strength, thickness, CSA, and stiffness (p < 0.05, BFincl > 1) and, in intragroup comparisons, both groups showed improvements in these parameters (p < 0.05, BF10 > 1). A statistically significant decrease in subcutaneous fat thickness was observed in the BFR-RE group (p < 0.05, BF10 > 1), while this change was not observed in the HL-RE group (p > 0.05, BF10 < 1). Similarly, a statistically significant increase in right rectus femoris muscle stiffness was detected in the BFR-RE group (p < 0.05, BF10 > 1) but not in the HL-RE group (p > 0.05, BF10 < 1). Furthermore, time’s main effect was statistically insignificant for thigh circumference (p > 0.05, BFincl < 1). The group × time interaction was statistically significant only for peak power leg flexion left (p < 0.05, BFincl > 1), and a statistically significant difference in favor of the BFR-RE group was observed in the intergroup comparisons (p < 0.05, BF10 > 1). Conclusions: In conclusion, BF-RE exercise with voluntary exhaustion may be as effective as HL-RE for hypertrophic adaptations in untrained young males.
How Much Influence Do Political Factors Have on Environmental Degradation in MENA Countries? The Method of Moments Quantile Approach
(WILEY, 111 RIVER ST, HOBOKEN 07030-5774, NJ, 2025) Çelik, Ali
Compared to economic and social factors, political factors play an important role in achieving environmental sustainability goals. Furthermore, an adequate understanding of the impact of political factors on environmental degradation can contribute positively to slowing the pace of climate change by guiding climate policy. This study examines the role of globalization, democracy, and political corruption on ecological footprint and material footprint based on the Environmental Kuznets Curve (EKC) hypothesis in the selected 15-Middle East and North Africa (MENA) countries over the period between 2001 and 2021 employing advanced panel data analysis. The empirical findings suggest that (i) the EKC hypothesis is valid in MENA countries in terms of material footprint, that is, GDP has an inverted U-shaped relationship with material footprint (the turning point of the EKC is 83.173.522.697$), but ecological footprint increases monotonically with GDP based on random effects (RE) estimation results with robust standard errors. However, the Method of Moments Quantile Regression (MMQR) estimation revealed that the EKC hypothesis is valid in terms of ecological footprint for lower quantiles; (ii) globalization increases the ecological and material footprints, that is, it threatens environmental sustainability; (iii) the development of democracy decreases the ecological and material footprints, that is, democracy contributes to environmental sustainability; (iv) the increase in political corruption boosts the ecological footprint and, as an interesting result, decreases the material footprint. To the end, the findings will provide a qualified contribution to the emergency action plans that need to be prepared for authorities, policymakers, and decision makers in the MENA countries to prevent climate change. Indeed, policies developed to prevent climate change should be multi-dimensional.
In vitro glycemic index, antioxidant capacity, and sensorial properties of breads enriched with broccoli sprouts
(EMERALD GROUP PUBLISHING LTD, Floor 5, Northspring 21-23 Wellington Street, Leeds, W YORKSHIRE LS1 4DL, ENGLAND, 2025) Bayram, Hatice Merve; Özkan, Kübra; Yıldırım, Güldane; Yılmaz, Melike Yağmur; Öztürkcan, Arda Seyfettin; Sağdıç, Osman
Purpose – This study aims to investigate the glycemic index (GI), total phenolic content, total flavonoid content, antioxidant capacity and sensory properties of the breads enriched with fresh and freeze-dried (FD)- broccoli sprouts (BS). Design/methodology/approach – Broccoli was sprouted using a home germination system. The bread was made with organic wheat flour consisting of fresh and FD-BS. The moisture content of the breads was measured using a moisture meter. The texture properties of raisins were measured by a texture analyzer. Total phenolic contents (TPC), total flavonoid contents (TFC) and antioxidants assays (DPPH, ABTS, FRAP) and the in vitro GI of breads were determined. Additionally, the hedonic test was used to determine the degree of overall liking for the breads based on the degree of liking or disliking according to a five-point hedonic scale. Findings – Enriching organic bread with fresh and FD-BS significantly increased the total phenolic, flavonoid contents and antioxidant capacities, with the most pronounced effects observed in breads enriched with FD-BS (p< 0.05). The GI values of breads vary between 69.8 and 73.4. Increased green color, crust and crumb color intensity were observed in BS-enriched breads (p< 0.05). The general acceptance of breads was not affected by addition of BS. Originality/value – This study addresses the effects of FD-BS incorporation into organic wheat flour bread demonstrating that they reduce the in vitro GI and increase the TPC, TFC and antioxidant power. The findings could open up new opportunities for food processors and sustainable nutrition.
Understanding Muslim tourist behavior in non-Muslim countries through the stimulus–organism– response framework
(EMERALD GROUP PUBLISHING LTD, Floor 5, Northspring 21-23 Wellington Street, Leeds, W YORKSHIRE LS1 4DL, ENGLAND, 2025) Çıkı, Kartal Doğukan; Tanrıverdi, Haluk
Purpose – The purpose of this study is to explore the effects of Muslim-friendly tourism (MFT) characteristics in non-Muslim countries on Muslim tourists’ destination loyalty (DL) and subjective wellbeing (SWB) by adopting Stimulus–Organism–Response theory. Additionally, this research seeks to determine the effects of DL and SWB on revisit and recommendation intentions. Design/methodology/approach – In line with the purpose of this research, a model was proposed, and an online survey was applied to Turkish tourists (n = 257) to test the relationships in this model. AMOS software was used to validate the proposed model. Findings – The analysis revealed that most of the proposed relationships were supported, except for the impact of MFT characteristics on SWB and the influence of halal food on DL. These results indicate that while most MFT features positively influence both DL and SWB, local people’s behaviors do not significantly affect DL, and the social environment does not significantly impact SWB. Practical implications – This research creates the potential to better understand the travel preferences of Muslim tourists from a cross-cultural perspective and the factors that shape their holidays. The findings of this study can be used by tourism marketers and policymakers in non-Muslim countries to develop strategies that cater to the needs and preferences of Muslim tourists, thus enhancing DL and encouraging positive word-ofmouth recommendations. Originality/value – This research provides valuable insights into the travel behaviors and preferences of Muslim tourists, a relatively under-researched demographic in the context of non-Muslim countries. By focusing on MFT features and their impact on DL and SWB, this research contributes to the existing literature and offers practical guidelines for improving the Muslim tourist experience.
Equipping Police officers with resources: perceived control of internal states and suicide tendencies among Turkish Police officers, unraveling the serial mediating roles of resilience and depression
(SPRINGER, ONE NEW YORK PLAZA, SUITE 4600 , NEW YORK, NY 10004, UNITED STATES, 2025) Padır, Mehmet Ali; Doğrusever, Caner; Tansel, Bülent; Vangölü, Mehmet Sıddık
Drawing from existing literature, this study highlights police officers’ heightened vulnerability to depression and suicidality as a result of occupational stressors and investigates the intricate associations among Turkish police officers’ perceived control of internal states (PCOIS), resilience, depression, and suicidal tendencies. The study uses a comprehensive analysis to investigate how PCOIS influences resilience and depression, which subsequently impact suicidal tendencies. A total of 628 police officers participated in the study voluntarily. The mediation analyses indicate individuals with high PCOIS levels tend to have higher resilience, thus leading to lower suicidality regardless of depression levels. High PCOIS levels have also been linked to lower depression levels, thus also leading to a decrease in suicidality independent of resilience. The study shows both resilience and depression to be affected by PCOIS levels, with resilience acting as a protective shield against suicidality, whereas depression exacerbates the likelihood of suicidality. Lastly, the study has uncovered a serial mediating effect, with higher PCOIS levels enhancing resilience and subsequently reducing depression and suicidal tendencies. Therefore, resilience and depression play crucial roles as serial mediators in the relationship between PCOIS and suicidality, underscoring PCOIS’s importance in psychological interventions aimed at bolstering resilience and mitigating depression and suicidality among police officers. This study contributes uniquely to the literature by demonstrating PCOIS’s protective role in a high-stress profession and provides practical implications for developing targeted mental health interventions.
