Dissident Women's Organizations as A Counter-Hegemonic Actor in Turkey
(TURKISH STUDIES, 2024) Gunduz, Melisa; Gencoglu, Funda
Could the Turkish women's movement, which has a strong reaction mechanism, be a constituent actor of counter-hegemony? The main reasons behind this question are the women's movement's deep-rooted history and its openness to combine theory with practice/action. When looked from the Chantal Mouffe and Ernesto Laclau's perspective of radical democracy theory, the women's movement appears to have a considerable potential of deciphering the existing hegemony and articulating the social demands which exclude and are excluded by the present-day hegemony in Turkey. This article tries to understand how women's movement in Turkey conceptualizes the existing power relations that constitute the neoliberal religio-conservative hegemony and how it responds to it.
Does Chronic Subjective Tinnitus Affect Cognitive Performance In Adults with Hearing Thresholds of 25 dB and Less Between 0.5-4 kHz
(JOURNAL OF THE AMERICAN ACADEMY OF AUDIOLOGY, 2024) Deniz-Sakarya, Merve; Cinar-Satekin, Merve; Yaldiz, Zahide C. B.; Tokgoz-Yilmaz, Suna
Background In literature, the cognitive performance results of normal hearing individuals with tinnitus are inconsistent. It also differs in the control of other factors that may affect cognition. Purpose This study aimed to determine the differences in attention and memory performance between normal hearing individuals with chronic subjective tinnitus and age-sex-education-matched healthy controls. Study Sample Normal hearing individuals with subjective chronic tinnitus between 18 and 55 years of age, who have normal cognitive abilities (tinnitus group, n = 30) and age-sex-matched normal hearing individuals without tinnitus who have normal cognitive abilities (control group, n = 30) were included in this study. Data Collection The Montreal Cognitive Assessment Test measured participants' general cognitive screening, and depressive symptoms were measured by Beck Depression Inventory (BDI). Tinnitus Handicap Inventory was used to determine the tinnitus handicap levels. Attention performance was evaluated with Stroop Test-TBAG Form, and short-term and working memory performances were evaluated with the Wechsler Adult Intelligence Scale-Revised (WAIS-R)-Digit Span Test. Results The tinnitus and control groups' depressive symptom scores were similar concerning the BDI ( p = 0.90). There was no statistically significant difference between both groups according to the completion time of the five sections of the Stroop Test, the number of errors and corrections of the Stroop 5 test, and the (WAIS-R)-Digit Span Test scores ( p > 0.05). Conclusion In our study, the Stroop Test and Digit Span Test performances of individuals with tinnitus and normal hearing were similar to the control group. Despite previous studies claiming an effect of tinnitus on cognition, our contrary findings are discussed in the light of other demographic, audiological, and psychological measurement variables, especially hearing loss.
Early Breast Development In Girls: The Power Of Greyscale Sonography And Sonoelastography
(Başkent Üniversitesi Sağlık Biimleri Fakültesi, 2024-02-27) Keceli, Merter; Akyurek, Nesibe
Objective: Accurate distinction between central pubertal precociousness (PP) and premature thelarche (PT) is important to guide treatment. Both greyscale ultrasonography (US) and sonoelastography can be used to examine breast tissue. The aim of this study is to investigate the performance of breast US and strain elastographic (SE) in the diagnosis of increased breast volume in girls. Methods: Sixty-three girls with breast development up to 8 years of age and diagnosed with PP and PT were included in the prospective study. Basal luteinizing hormone (LH), follicle-stimulating hormone (FSH), and estradiol (E2) values were obtained. Each bud was considered as a unit in US. Mediolateral (ML) and anteroposterior diameters (AP) were measured, and US grading was performed. Breast SE was examined, and strain index (SI) was calculated. US and laboratory findings were compared. Results: Of the 121 buds examined, 39 (32.2%) were with PP (6.97 +/- 2.44 years) and 82 (67.8%) were with PT (6.51 +/- 2.52 years). Diameters were correlated with bone age, LH, FSH, and US grade. The mean AP showed a moderate difference in favour of PP between the groups (P < .06). The mean ML was higher in PP (P < .01). There was a difference in mean SI values (P < .004). Sensitivity and specificity were 71% and 61% for ML and 72% and 56% for SI, respectively. Conclusion: Both ML and US grading may help discriminate PP from PT. The role of sonoelastography requires further investigation.
Economic Burden Of Short-Acting Beta-2 Agonist (Saba) Overuse Among Asthma Patients In Türkiye: A Cost Analysis With Respect To The Updated Gina Treatment Recommendations
(BMC PULMONARY MEDICINE, 2024-10-21) Yorgancioglu, Arzu; Aksu, Kurtulus; Cura, Ceyhun; Yaman, Yigit; Dinc, Melda; Malhan, Simten
BackgroundThis cost of illness study aimed to determine economic burden of short-acting beta 2-agonist (SABA) overuse in T & uuml;rkiye from payer perspective with respect to the updated GINA 2022 treatment recommendations.MethodsA total of 3,034,879 asthma patients comprised the study population, via estimations extrapolated from the T & uuml;rkiye arm of the global SABINA III study. The economic burden (costs related to the drug use and severe exacerbations) was compared in subgroups of overall (>= 0 canisters/year) vs. GINA-recommended (0-2 canisters/year, hypothetical population) SABA use and in subgroups of appropriate use (0-2 canisters/year, real population) vs. overuse (>= 3 canisters/year) of SABA with extrapolation of SABINA T & uuml;rkiye data to the T & uuml;rkiye asthma population.ResultsRecommended SABA use was predicted to prevent 127,505 of 157,512 severe exacerbations per year in mild asthma patients and 2,668,916 of 3,262,800 severe exacerbations per year in moderate-severe asthma patients. Annual cost burden of not applying recommended SABA use (overall [>= 0 canisters/year] vs. GINA-recommended [0-2 canisters/year] SABA use) in mild asthma and moderate-severe asthma patients was calculated to be 20.43 million and 427.65 million in terms of severe exacerbations, and to be 829,352 and 7.20 million in terms of drug costs, respectively. The total annual economic burden arising from not applying recommended SABA use was estimated to be 456.11 million. Appropriate use (0-2 canisters/year) vs. overuse (>= 3 canisters/year) of SABA was associated with decreased frequency of severe exacerbations per year in mild asthma (from 129,878 to 27,634) and moderate-severe asthma (from 2,834,611 to 428,189) patients. SABA overuse in mild and moderate-severe asthma patients was estimated to yield an additional annual cost of 16.38 million and 385.59 million, respectively in terms of severe exacerbations, and a total 11.30 million additional drug cost. The overall annual economic burden arising from SABA overuse was estimated to be 413.27 million.ConclusionsThe estimated annual total economic burden arising from not applying recommended SABA use (456.11 million) and SABA overuse (413.27 million) with respect to the updated GINA 2022 treatment recommendations indicates the substantial cost burden of SABA overuse to the Turkish National Health System, corresponding up to 26% of the total direct cost of asthma reported in our country.

(ISTANBUL BUSINESS RESEARCH, 2024-12) Ozkan, Ayse Arslan; Yildiz, Erkan
This study examines the relationships among festival success factors, festival satisfaction, destination image and destination loyalty. Based on the literature review, festival success factors were identified and a model was developed to measure the direct impact of these factors on destination loyalty and the impact of these factors through the overall image of the destination. Data were collected during the 11th Ala & ccedil;at & imath; Herb Festival held between March 24-27, 2022. The data obtained were analyzed with the structural equation modeling. According to the results of the study, the program, festival area, staff, souvenirs, and information dimensions of festival success factors affect festival satisfaction. The effects of convenience and food dimensions on festival satisfaction were statistically insignificant. The festival satisfaction and destination overall image variables have positive effects on destination loyalty, and the festival satisfaction variable has positive effects on the destination overall image. The destination overall images an integral partial mediating role in the relationship between festival satisfaction and destination loyalty.
Effect Of Hamstring Flexibility On Cervical Range Of Motion And Deep Neck Flexor Endurance In Healthy Young Adults: A Study To Explore Myofascial Tensegrity Network
(Başkent Üniversitesi Sağlık Bilimleri Fakültesi, 2024-07-16) Ozyurek, Seher; Aktar, Burcin; Kosova, Altay; Aydin, Ebru; Turedi, Rubeysa; Pekyavas, Nihan Ozunlu
Introduction: According to the concept of biotensegrity, the whole body consists of fascial lines. The relationship between muscles and fascia is important to ensure full and proper range of motion. This study investigated the effect of hamstring flexibility on cervical range of motion and deep neck flexor muscle endurance. The aim was to explore the relationship between the hamstring muscles and neck region in the myofascial tensegrity network. Method: Sixty healthy participants with a median age of 22.0 years (24 male, 36 female) were included. Hamstring flexibility was categorized as "normal (n = 31)" or "limited (n = 29)" according to hip flexion angle (HFA) using the passive straight leg raise (PSLR) test. Active cervical range of motion was measured by the Clinometer smartphone application, and the following movements were recorded: flexion, extension and lateral flexion. The craniocervical flexion test was performed to evaluate deep neck flexor endurance using performance index and highest-pressure score. The Mann-Whitney U test was used for statistical analysis. Results: No significant differences in cervical range of motion were observed between the groups (p > 0.05). Participants with limited hamstring flexibility presented lower deep neck flexor muscle endurance scores (performance index and highest-pressure score) than participants with normal hamstring flexibility (p = 0.002, and p = 0.012, respectively). Conclusion: The results suggest that hamstring flexibility can influence deep neck flexor muscle endurance in healthy young adults. This preliminary clinical finding supports the hypothesis of a myofascial network between the hamstring muscles and neck region.
Effect of Microwave-Vacuum Drying on the Physicochemical Properties of a Functional Tomato Snack Bar
(JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE, 2024) Gul, Muhammed Rasim; Ince, Alev Emine; Ozel, Baris; Uslu, Aymelek Kubra; Cetin, Melis; Mentes, Duygu; Sumnu, Servet Gulum; Oztop, Mecit Halil
BACKGROUND: Tomato is an indispensable ingredient of the Mediterranean diet. Reformulation of traditional Mediterranean products to increase the adherence of consumers is becoming popular. In this study, a tomato snack bar enriched with olive powder and pea protein was developed by using microwave-vacuum drying. Formulations also included tomato powder (TP) and low-methoxylated pectin (LMP) as a structuring agent. RESULTS:The moisture content of microwave-vacuum-dried samples varied in the range 13.6-19.8% and water activity (a(w)) values were similar to 0.6. LMP and TP concentrations affected the color of microwave-vacuum-dried samples. However, the color mainly changed in conventionally dried samples due to browning. In microwave-vacuum-dried samples, lycopene content decreased with increasing LMP, but increased with increasing TP. Textural properties of microwave-vacuum-dried snack bars increased with increasing LMP and TP. CONCLUSION: Both texture and Fourier transform infrared spectroscopy results indicated that there was a network formation due to the contribution of protein and pectin; however, the type of interaction was highly dependent on the drying mechanism. Nuclear magnetic resonance relaxometry data showed that microwave-vacuum-dried samples had a more uniform water distribution. Besides its time and energy efficiency, microwave-vacuum drying improved the color and textural properties of tomato snack bars compared to conventionally dried ones. (c) 2023 The Authors.

Effect Of Ultrasonic And Sonic Instrumentation On Shear Bond Strength Of Resin Composite To Enamel: An In Vitro Study
(AMERICAN JOURNAL OF DENTISTRY, 2024-04-12) Adiguzel, Ruhsan Muduroglu; Mustafa, Abdelrahman; Oduncuoglu, Bahar Fusun; Colak, Mew Yavuz; Gulsahi, Aye; Arhun, Neslihan
Purpose: To assess and compare the effects of sonic and ultrasonic instrumentation on shear bond strength (SBS) and investigate the influence of adhesive system application modes (etch&rinse/self-etch) on SBS. Methods: In this experimental study, 45 extracted sound human molars were selected. Mesial and distal surfaces of the teeth were abraded until 90 smooth enamel surfaces were obtained. Specimens were divided into two groups, with half (N= 45) conditioned in etch&rinse mode and the remaining (N= 45) in self-etch mode using Tetric N Bond Universal. Composite resin discs were produced on these surfaces by filling Teflon molds. All specimens were aged via thermocycling. Each group was further divided into three more groups (n= 15) according to the type of periodontal instrumentation (ultrasonic, sonic or none). SBS values were recorded and analyzed using two-way ANOVA. Fracture sites were examined under a stereomicroscope. Results: The type of periodontal instrumentation had no significant effect on SBS values, whether sonic, ultrasonic or their absence (P= 0.945). The type of adhesive system mode had a significant influence on the shear bond strength values. Etch&rinse groups had significantly higher shear bond strength values than self-etch groups (P< 0.001).
Effective Health Communication Depends on the Interaction of Message Source and Content: Two Experiments on Adherence to COVID-19 Measures in Türkiye
(PSYCHOLOGY & HEALTH, 2024) Bayrak, Fatih; Aktar, Bengi; Aydas, Berke; Yilmaz, Onurcan; Alper, Sinan; Isler, Ozan
ObjectiveFollowing the COVID-19 outbreak, authorities recommended preventive measures to reduce infection rates. However, adherence to calls varied between individuals and across cultures. To determine the characteristics of effective health communication, we investigated three key features: message source, content, and audience.MethodsUsing a pre-test and two experiments, we tested how message content (emphasizing personal or social benefit), audience (individual differences), message source (scientists or state officials), and their interaction influence adherence to preventive measures. Using fliers advocating preventive measures, Experiment 1 investigated the effects of message content and examined the moderator role of individual differences. Experiment 2 presented the messages using news articles and manipulated sources.ResultsStudy 1 found decreasing adherence over time, with no significant impact from message content or individual differences. Study 2 found messages emphasizing 'protect yourself' and 'protect your country' to increase intentions for adherence to preventive measures. It also revealed an interaction between message source and content whereby messages emphasizing personal benefit were more effective when they came from healthcare professionals than from state officials. However, message source and content did not affect vaccination intentions or donations for vaccine research.ConclusionEffective health communication requires simultaneous consideration of message source and content.
Effects of Delayed-Onset Muscle Pain on Respiratory Muscle Function
(SPORTS HEALTH-A MULTIDISCIPLINARY APPROACH, 2024-11) Ozden, Sema; Ozalp, Ozge; Kilic, Rabia Tugba; Yosmaoglu, Hayri Baran
Background: Delayed-onset muscle soreness (DOMS) has been widely examined in the peripheral muscles; however, studies showing the potential effects of DOMS on respiratory function are limited.Hypothesis: DOMS in trunk muscles has a negative effect on respiratory function parameters, respiratory muscle strength, respiratory muscle endurance, and exercise capacity.Study design: Prospective cohort study.Level of evidence: Level 2.Methods: In 24 healthy participants with a mean age of 21 +/- 2 years, DOMS was induced for the trunk muscles with a load equal to 80% of the maximum repetitive voluntary contraction. Pulmonary function parameters, respiratory muscle strength and endurance, exercise capacity, pain, fatigue, and dyspnea perception severity were recorded before DOMS and at 24 and 48 hours after DOMS.Results: After DOMS, decreases were observed in respiratory function parameters, namely, forced vital capacity, forced expiratory volume in the first second, vital capacity, and 25% to 75% flow rate value of forced expiratory volume (25% to 75%) (P = 0.02, P = 0.02, P < 0.01, P = 0.01, respectively). Maximal inspiratory pressure and exercise capacity also decreased (P = 0.02, P < 0.01, respectively). No difference was observed between all 3 measurements of maximal expiratory pressure (MEP) and MEP% values (P-1 = P-2 = P-3 >= 0.99). The results of the respiratory muscle endurance tests did not reveal a significant difference in terms of load and time in all 3 conditions (P > 0.05).Conclusion: After DOMS, there was a 4% to 7.5% decrease in respiratory function parameters, and a 6.6% decrease in respiratory muscle strength.Clinical relevance: The occurrence of DOMS before a competition can have a detrimental impact on pulmonary performance. Hence, it is imperative to consider this factor when devising training and exercise programs. In addition, the development of treatment protocols becomes crucial if DOMS arises.

(SOMATOSENSORY AND MOTOR RESEARCH, 2024) Aydogdu, Ecem Sevim Berk; Ersin, Aybuke; Kelecek, Selen; Melek, Mine; Pekyavas, Nihan Ozunlu
BackgroundMulti-gravitational suspension-based therapy (M-Gravity) is a comprehensive discipline based on the principles of non-gravity, which serves to increase the quality of life and holistic health of the individual with the rehabilitation content of non-pressure inversion therapy and suspension systems.AimsTo examine the effects of M-Gravity exercise on posture, physical fitness, quality of life, depression, and sleep quality in women without regular exercise habits.MethodsThis study included 20 women without regular exercise habits, who participated in M-Gravity exercise and 20 women who did not participate in any exercise program. Posture was measured by the New York posture rating chart, flexibility of the hamstring and pectoral muscles were assessed with flexibility tests, and endurance of the core muscles was measured with plank test. Depression levels were measured by Beck Depression Inventory, sleep quality was measured by Pittsburgh Sleep Quality Index, and Nottingham Health Profile was used to measure the perceived health levels of the subjects. Measurement of the core stability was performed with the Stabilizer Pressure Biofeedback. Two evaluations were made at baseline and after 4 weeks of exercise program.ResultsAlthough statistically significant results were achieved for all parameters in the M-Gravity group, no differences were observed in the control group between baseline and post-test scores (p < 0.05).ConclusionsWe came to the idea that eight sessions of M-Gravity program may have positive effects on posture, physical fitness and quality of life in women who do not have regular exercise habits.

(TURKISH JOURNAL OF PHYSIOTHERAPY REHABILITATION-TURK FIZYOTERAPI VE REHABILITASYON DERGISI, 2024-12) Kalkan Balak, Busra; Ozlem Yuruk, Zeliha
Purpose: This study aims to compare the effects of pilates and whole-body vibration exercise training on body composition, flexibility, balance, and functional strength of core muscles in healthy women. Methods: Thirty-six healthy women were divided into three groups: a pilates group, a whole-body vibration (WBV) exercise group, and a control group. The pilates group received training using the 'Reformer (R),' while the WBV group used the 'Power Plate (R).' Both groups trained twice a week for eight weeks, with sessions lasting 45-60 minutes each. The control group did not receive any training. Body composition was assessed using body mass index (BMI), the waist-to-hip ratio, and bioelectrical impedance analysis. Sit-and-Reach Test for flexibility, Functional Reach Test for balance, and Sit-ups and Modified Push-ups Test for core muscle strength. Assessments were made before and after training. Results: In the group comparisons, significant differences in BMI and some bioelectrical impedance parameters were observed in the WBV group (p<0.05). However, no significant changes in body composition were found in the pilates and control groups and no difference was found between the three groups (p>0.05). Flexibility showed significant differences among the three groups (p<0.01). Functional core strength increased in both the pilates and WBV groups (p<0.05), but no significant differences were observed in balance and strength comparisons between the groups (p>0.05). Conclusion: Results indicate that WBV training affected body composition, and both exercise groups improved flexibility, balance, and core strength. However, WBV was not superior to pilates. Further research is needed for generalizability.

(Başkent Üniversitesi Sağlık Bilimleri Fakültesi, 2024-05-03) Yagiz, Seyda Uzun; Isik, Sevcan Avci
PurposeMultiple effective nursing interventions are needed to manage deviations from normal vital signs and fatigue experienced by kidney transplant patients. In this study, we investigated the effect of progressive muscle relaxation (PMR) exercises on vital signs and fatigue in kidney transplant patients.MethodWe conducted a randomized controlled experimental study with 52 patients (intervention = 26, control = 26) who underwent kidney transplantation at a university hospital in Turkey and met the inclusion criteria. The "Descriptive Characteristics Form", "Vital Signs Monitoring Form", and "Fatigue Severity Scale" were used to record data on the patients. Then, the patients in the intervention group (baseline assessment) were trained to perform PMR exercises, asked to practice, and followed up (first follow-up). Patients were recommended to perform PMR exercises for 20 min every day for four weeks. The second follow-up in the second week after discharge and the third follow-up at the end of the fourth week were performed in the outpatient clinic.ResultsWe found that the pulse rate, body temperature, and arterial blood pressure decreased over time and oxygen saturation increased in the patients of the intervention group. The PMR exercises decreased fatigue in these patients. The arterial blood pressure and oxygen saturation values differed significantly across different time points among the patients in the control group. The difference in the scores of fatigue severity between the pre-follow-up and the third follow-up in the control group was not significant.ConclusionPMR exercises were found to be an effective nursing intervention in regulating vital signs and reducing fatigue in renal transplant patients.
Electrospun Hesperidin Nanofibers Induce A Cytoprotective Effect On Sodium-Fluoride Induced Oxidative Stress In Vitro
(JOURNAL OF DRUG DELIVERY SCIENCE AND TECHNOLOGY, 2024-03-08) Birer, Mehmet; Kara, Adnan Altug; Yurdakok-Dikmen, Begum; Uyar, Recep; Aralan, Gizem; Birer, Yagmur Turgut; Filazi, Ayhan; Acartuerk, Fusun
As a bioactive flavonoid in Citrus seeds, hesperidin exerts significant antioxidant, free radical scavenging, and anticancer activity with limited bioavailability. To enhance the stability and improve the bioactive potential of hesperidin, an electrospun nanofiber formulation was developed. Electrospinning solution was characterized by surface tension, viscosity, and conductivity measurements, and these values were found to be 25.18 +/- 0.04 mN/ m 145 +/- 2 cPs and 9.0 +/- 0.4 mu S/cm, respectively. Electrospun hesperidin nanofiber was tested in a coincubation with the cytotoxic agent sodium fluoride (NaF) in Caco-2 cells. Inhibitory concentration-50 (IC50) values of hesperidin nanofiber in Caco-2 cells alone were as low as 30 mu M, indicating its potential anticancer effect, while coincubation with 10 and 20 mu M of hesperidin nanofibers was found to alleviate the cytotoxic effect induced by NaF at 2.1, 1.05 and 0.525 mM concentrations. This effect was in accordance with cellular antioxidant mechanisms; where malondialdehyde (MDA) levels at 10 mu M hesperidin nanofiber were found to be decreased by 55.60% in the thiobarbituric acid reactive substances (TBARS) assay, and the mRNA expression of Thioredoxin1 (TRX1) and Superoxide dismutase-1 (SOD1) were decreased in qPCR. The results revealed that electrospun nanofiber of hesperidin was developed for the first time with useful implications against cellular toxicity by alleviating the cellular antioxidant defense mechanisms, including MDA, SOD1, and TRX1.
Emotional Wellbeing and Life Satisfaction of Singles and Mated People Across 12 Nations
(EVOLUTIONARY PSYCHOLOGICAL SCIENCE, 2024-12) Apostolou, Menelaos; Tekes, Burcu; Blachnio, Agata; Sullman, Mark; Costello, William
The increasing occurrence of singlehood raises the question of whether people enjoy greater emotional wellbeing alone or in an intimate relationship. Guided by an evolutionary theoretical framework of human emotions, the current research aimed to address whether individuals are emotionally better off single than in an intimate relationship, taking a cross-cultural perspective. The quality of the relationship is also crucial; thus, the study also aimed to determine whether individuals in a good or bad intimate relationship differ from each other and from those who are single in terms of emotional wellbeing. In a sample of 6338 participants from 12 nations, we found that singles experienced lower emotional wellbeing and life satisfaction than those in relationships. More specifically, participants who were in a relationship or married reported the highest life satisfaction and emotional wellbeing, while those involuntarily single reported the lowest levels, with individuals who are between relationships or voluntarily single reporting intermediate levels. Additionally, participants in a good relationship experienced higher emotional wellbeing and life satisfaction than those in a bad relationship. The findings among the involuntarily single participants were similarly negative, but to a lesser extent than those in a bad relationship. These results were consistent across the different nations in our sample.

(ARCHIVES OF PSYCHIATRIC NURSING, 2024-12) Topal, Cansu Akdag; Ucgun, Tugce; Gurel, Reyyan
Objective: The research aims to understand the factors influencing nursing students' attitudes towards the LGBTI community, given the importance of culturally competent and inclusive care in healthcare. Method: A descriptive and relationship-seeking design was used. The study was completed by 386 nursing students. Data were collected with "Personal Information Form, LGBTI Attitude Scale (LGBTI-AS) and Toronto Empathy Scale (TEQ)". Hierarchical regression analysis was used to identify predictors of attitudes towards LGBTI individuals among nursing students. Results: The total mean score of the Awareness to LGBTI Attitude Scale was 2.47 +/- 1.0 (moderate attitudes). The findings revealed that female students and senior nursing students exhibited more positive attitudes, while those with friendships with LGBTI individuals and higher empathy levels showed greater acceptance and understanding towards the LGBTI community (p p < 0.001). The results showed that 22 % of the total variance in the LGBTI attitude could be explained in model 3 (F = 27.43, R2 variation = 0.224, p = 0.001). Conclusion: The study highlights the importance of integrating LGBTI-related content into nursing curricula and promoting empathy-building activities. These findings underscore the significance of empathy in shaping positive attitudes and emphasize the need for comprehensive educational strategies to promote inclusivity in healthcare.
Empathy Increases Warmth Toward Syrian and Afghans, but not Ukrainians: Experimental Evidence from Türkiye
(INTERNATIONAL JOURNAL OF INTERCULTURAL RELATIONS, 2024) Aktas, Busra Eylem; Salter, Metin Ege; Yilmaz, Ayse Nur; Eker, Selin
Previous research has documented that economic concerns might limit the positive impact of empathy in reducing prejudicial attitudes toward refugees in Turkiye. Other research has also shown that religious conservatism might buffer negativity toward refugees. However, there has been no prior research testing whether empathizing with economic hardships would increase positivity toward refugees. In this study, we aimed to investigate the role of empathy by leading individuals to adopt the perspective of those experiencing the detrimental effects of resource scarcity among Turkish citizens. Specifically, we examined whether inducing empathy related to resource scarcity would increase the level of warmth felt toward Syrian, Afghan, and Ukrainian refugees, while considering the moderating roles of religiosity and conservatism in this relationship. The present study employed a between-subjects design experiment wherein participants were randomly assigned to either the control group (n = 131) or the experimental group (n = 110). The results showed that participants in the experimental group reported higher levels of warmth toward Syrians and Afghans but not toward Ukrainians when compared to the control group. Moreover, there were significant moderator roles for religiosity and conservatism in the link between induced empathy and warmth toward Syrians. Specifically, the present findings demonstrate that higher levels of religiosity and conservatism positively predict the association between empathy induction and higher levels of warmth toward Syrians but not toward Ukrainians and Afghans. Overall, these results suggest that empathizing with the scarcity of resources might be an effective approach to reducing negative attitudes toward Afghan and Syrian refugees, but it may not have the same impact on Ukrainians in the Turkish cultural context. Furthermore, these findings indicate that higher levels of conservatism and religiosity can contribute to a positive impact of empathy toward Syrians.
Enhancing Carbon Fiber Reinforced Aluminum Laminates With Cellulose Paper Interlayers: Experimental Characterization Of Tensile, Flexural, And Interlaminar Fracture Toughness
(Başkent Üniversitesi Mühendislik Fakültesi, 2024-03-30) Ustun, Tugay; Guler, Ebru Saraloglu
The mechanical properties of fiber metal laminates (FML) are influenced by several various factors. Interface adhesion plays a particularly crucial role in interlaminar strength. Enhancing the interlaminar strength of carbon fiber reinforced aluminum laminate (CARALL) composites present a persistent challenge due to inherent weaknesses between metal and composite elements. Therefore, this study focuses on improving the interlaminar performance of CARALL composites by introducing cellulose paper interlayer at the metal/composite interface. The cellulose paper interlayer offers the advantage of being cost-effective and sustainable. Cellulose paper-interleaved CARALL composites were fabricated by vacuum bagging method and exhibited noteworthy improvements in mechanical properties. Comparative analysis with pristine samples revealed substantial enhancements, including a 15% increase in tensile strength, a remarkable 42% improvement in flexural strength, and a significant enhancement in mode-I fracture toughness by 65%. Furthermore, the cellulose paper interleaving played a crucial role in stabilizing fracture formation at the fiber-matrix interface, with mode II fracture toughness witnessing a 3% increase. Visual examination revealed the underlying toughening processes occurring in the interfacial area. This innovative approach of interleaving laminated composites with cellulose paper emerges as a sustainable and effective strategy, demonstrating the potential to fortify and toughen the interlaminar zones of CARALL composites.

Evaluating Efficiency of Cloud Service Providers in Era of Digital Technologies
(ANNALS OF OPERATIONS RESEARCH, 2024) Azadi, Majid; Toloo, Mehdi; Ramezani, Fahimeh; Saen, Reza Farzipoor; Hussain, Farookh Khadeer; Farnoudkia, Hajar
The rapid growth of advanced technologies such as cloud computing in the Industry 4.0 era has provided numerous advantages. Cloud computing is one of the most significant technologies of Industry 4.0 for sustainable development. Numerous providers have developed various new services, which have become a crucial ingredient of information systems in many organizations. One of the challenges for cloud computing customers is evaluating potential providers. To date, considerable research has been undertaken to solve the problem of evaluating the efficiency of cloud service providers (CSPs). However, no study addresses the efficiency of providers in the context of an entire supply chain, where multiple services interact to achieve a business objective or goal. Data envelopment analysis (DEA) is a powerful method for efficiency measurement problems. However, the current models ignore undesirable outputs, integer-valued, and stochastic data which can lead to inaccurate results. As such, the primary objective of this paper is to design a decision support system that accurately evaluates the efficiency of multiple CSPs in a supply chain. The current study incorporates undesirable outputs, integer-valued, and stochastic data in a network DEA model for the efficiency measurement of service providers. The results from a case study illustrate the applicability of our new system. The results also show how taking undesirable outputs, integer-valued, and stochastic data into account changes the efficiency of service providers. The system is also able to provide the optimal composition of CSPs to suit a customer's priorities and requirements.
