- MakaleYalnız künye2026How does social capital affect the relationship between perception of diversity management and affective commitment?
Yilmaz Atik, Emine; Özbek, Mehmet Ferhat
PurposeThe aim of this study is to reveal the moderating effect of social capital in the relationship between employees' perceptions of diversity management and their affective commitment.Design/methodology/approachThe research hypotheses developed within the relevant literature framework are tested by using data that was obtained from the academic staff members who work at the Turkish universities.FindingsThe findings indicate that the relationship between perceptions of diversity management and affective commitment, considered in the dimensions of social capital such as participation in the local community, socio-proactivity, family and friendship relationships, tolerance for diversity, work relationships, quality of life and trust, vary according to strong and weak levels, supporting moderating hypotheses at various levels.Research limitations/implicationsOne of the significant limitations of the study is the reluctance of the sampled academicians to participate in a study related to diversity during the data collection process. Some academicians, in addition to express that they do not tolerate the diversity among employees within the organization, also decline to answer questions which are aimed at measuring these expressions.Practical implicationsThe study reveals that the perception of diversity management increases affective commitment. This finding suggests that managers should consider employees' perceptions of these policies rather than focusing solely on diversity management policies (Alshaabani and Rudnak, 2020: 2; Saleem et al., 2021: p. 1). In societies with collectivist cultures like T & uuml;rkiye, managers' practices become more important in strengthening employees' affective commitment (Wasti, 2000; Wasti, 2003). For employees to have positive perceptions of diversity management, managers should respect their identities, use inclusive language and form a positive diversity climate (Deepak and Perwez, 2019: p. 909). Furthermore, the audits evaluating diversity management practices should be conducted frequently (McKay and Avery, 2015: 334). However, the impact of employees' perceptions of diversity management on affective commitment may vary depending on employees' levels of social capital. Therefore, the organizations need to develop policies based on employees' levels of social capital. Orientation and mentoring programs should be implemented to facilitate the integration of employees with weak social relationships into the organization. The employees with strong social relationships should be guided toward social activities and club activities to capitalize on their strengths. The human resources department should develop some personalized programs for these employees.Social implicationsThe literature states that the perceptions and environment regarding diversity management have stronger relationships with attitudinal results rather than behavioral results (Holmes et al., 2020). The research findings support the literature in terms of showing that perception of diversity management have an impact on affective commitment. The collectivist cultural structure of the Turkish society (Sargut, 2001: p. 185) has an impact on the process of acquiring social capital. It is emphasized that the societal structure influences the behaviors exhibited by employees toward the organization. This study shows that the social capital of academics plays a partially moderating role in the relationship between perception of diversity management and affective commitment. When such dimensions of social capital as family and friendship relationships, socio-proactivity, work relations and tolerance for diversity are included in the relationship between the perception of diversity management and affective commitment, the direction and magnitude of the existing relationship change. Based on these results, it can be argued that their social capitals, which are formed based on secondary relationship types like friendship and acquaintance, contribute to the external social capital potential. In this aspect, the study is considered to contribute to the literature that highlights T & uuml;rkiye's high potential for external social capital (Bu & gbreve;ra, 1998; Oba and Semerci & ouml;z, 2004; & Ouml;zen and Aslan, 2006). In addition, it is fixed that socio-proactivity, family and friendship relationships, tolerance for diversity and work relationships, as the dimensions of social capital, have a negative moderating effect on the relationship between the perception of diversity management and affective commitment. These findings have determined the validity of the negative effects of social capital referred to as the dark side of social capital in the literature in the context of T & uuml;rkiye (Gargiolu and Bennasi, 1999; Gordon, 2020: 487; Lo and Fan, 2020: 27; Alcorta et al., 2020: 445).Originality/valueThe original value of this study is that the authors assume that the direction and magnitude of the relationship between the perception of diversity management and affective commitment are to be shaped according to the dimensions of social capital. In addition, it reveals that the affective commitment of employees can be shaped by social capital rather than perception of diversity management.

Agirkaya, Melahat Batu; Akyol, Hikmet
This research examines the impact of green innovation and digitalization on economic growth in Brazil, Russia, India, China, South Africa, and T & uuml;rkiye (BRICS+T) during the period 2002-2021. Within this framework, it analyzes the role of geopolitical risks and climate policy uncertainty. The relationships between variables were estimated using Pooled Bewley (CPS-BP), Dynamic Least Squares Mean Group (DOLS-MG), Fully Modified Least Squares (FMOLS), Canonical Cointegrated Regression (CCR), and Dynamic Least Squares (DOLS) estimators. Our results show that green innovation, digitalization, information technologies, infrastructure investments, life expectancy at birth, and US-originated climate policy uncertainties positively impacted economic growth. Increased geopolitical risks hindered growth in BRICS+T countries.
- MakaleAçık Erişim2026The Art of Dialectic (Jadal) in Ibn al-Mutahhar al-Hillī
Evmes, Adem; Akbay, Yunus Emre; Akyüz, Turgut
Al-Hilli, known as a Shii theologian and legal theorist, was a versatile scholar of the thirteenth century who authored numerous works on the philosophical sciences. In his writings, al-Hilli carefully examined ontological problems and methodological questions, systematically discussed the problem of knowledge, and devoted considerable attention to the science of logic. This article addresses al-Hilli's views on the art of dialectic (jadal), which he considered necessary for those who have not yet attained the level of demonstration (burhan), which ranks second in importance among the five arts, and on which no dedicated study has hitherto been undertaken. The aim of the article is to determine, on the basis of his logic works composed within the Peripatetic (Mash'sha'i) tradition, the extent to which al-Hilli was influenced by earlier logicians in his understanding of jadal and the respects in which he diverged from them. The scope of the article is confined to three of al-Hilli's works: his commentary on the logic section of Nasir al-Din al-Tusi's Tajrid al-i'tiqad, entitled al-Jawhar al-nadid; his commentary on al-Katibi's logical treatise al-Shamsiyya, entitled al-Qawa'id al-jaliyya; and his independent composition al-Asrar al-khafiyya fi al-'ul & umacr;m al-'aqliyya. These works were examined through a single-subject scanning method, whereby passages containing data pertaining to the components of dialectical theory-including its definition, premises, structure, and application-were identified and analysed. In this context, recourse was made to the works of logicians who had written on jadal prior to al-Hilli, among them Aristotle, al-Farabi, Ibn Sina, al-T & umacr;si, and al-Katibi, with particular attention given to a comparative analysis of the explanations offered by Ibn Sina and al-Hilli. It was ultimately established that al-Hilli followed both the Aristotelian and the Peripatetic logical tradition in his theory of jadal, and that he was especially influenced by Ibn Sina.

Köroglu, Ali; Yildiz, Salih
Brand dilution, which refers to new brand's damage to well-known brand's reputation and distinctive character by entering the market, is an understudied topic in marketing. Furthermore, there are very few studies comparing the effects of different levels of blurring and tarnishing. This study aims to fill this gap by examining the indirect impact of brand dilution on purchase intention through brand equity and by comparing the effects of blurring and tarnishing. For this purpose, a survey was conducted with 960 university students selected using a convenience sampling method. The conditional process model (Model 8) developed by Hayes (2018) was used in the research. The research results indicate a negative impact of brand dilution on brand equity dimensions and purchase intention. Additionally, brand awareness/association and brand loyalty play a mediating role in the relationship between brand dilution and purchase intention. Familiarity with the product category plays a moderating role in the relationship between brand dilution and brand awareness/association, brand loyalty, and purchase intention. As participants' familiarity with the product category increases, the influence of brand dilution on brand loyalty and purchase intention increases, while its influence on brand awareness/association decreases.

Kaderi, Sina; Ekinci, Can; Köse, Aydan Ayse
Background Today, people increasingly embrace the natural process of aging while seeking to age gracefully and elegantly. As a result, there has been growing interest in facelift and facial rejuvenation techniques. Patients tend to prefer methods that refresh the facial expression, offer natural-looking results, and leave minimal scarring. Objectives The authors describe a new technique and its tips that include short-scar facelift in addition to forehead and midface lift, especially for patients between the ages 35 and 50 with moderate skin sagging and excess. This procedure also includes intervention on the platysma muscle and all major retaining ligaments. Methods Seventy-four patients, all female, who were operated on with the TemFa lift technique described by the author, were evaluated with midface area measurements and Brow Positioning Grading Scale (BPGS), and the preoperative and postoperative results are presented. Results Compared with the preoperative results, the ratio of the upper midface area (P1) to the lower midface area (P2) increased significantly in the postoperative period (p < 0.05), while the BPGS results decreased significantly (p < 0.05), resulting in a younger eyebrow height and position. After the operation, the square face appearance is replaced by a more youthful V-shaped face. Conclusion TemFa lift technique can be considered as a suitable surgical technique for patients between the ages 35 and 50 who have moderate excess skin and sagging but also want some improvement in the neck and jawline area.

Soygenc, Elcin Izmir; Onur, Ozge Sahmelikoglu
Objective: Growing evidence suggests that unipolar mania (UM) may represent a distinct clinical condition rather than a subtype of bipolar disorder (BD). The present study aimed to compare the sociodemographic characteristics, clinical features, and psychosocial functioning of euthymic patients with UM or bipolar I disorder (BD-I) and healthy control subjects. Method: This cross-sectional study included euthymic patients with UM (n=58), BD-I (n=58), and healthy control subjects (n=58). Diagnoses were established according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria, and euthymia was confirmed using the Young Mania Rating Scale, Beck Depression Inventory, and Positive and Negative Syndrome Scale. Psychosocial functioning was assessed using the Functioning Assessment Short Test (FAST) in all groups and the Bipolar Disorder Functioning Scale (BDFS) in the UM and BD-I groups. Sociodemographic and clinical data were collected using a structured form. Group comparisons were conducted using appropriate parametric and nonparametric statistical analyses. Results: Both patient groups demonstrated significantly impaired psychosocial functioning compared with healthy controls across all FAST subdomains (p<0.05). On the BDFS, patients with UM showed better emotional functioning and less social withdrawal than patients with BD-I (p<0.05); however, total functioning scores did not differ significantly between groups (p>0.05). Clinically, UM was characterized by manic-predominant onset, higher rates of mood-congruent psychotic symptoms, longer episode duration, and more frequent hospitalizations. Suicidal behavior and total number of mood episodes were higher among patients with BD-I (p<0.05). In the final logistic regression model, mood-congruent psychotic symptoms during the first episode were independently associated with UM relative to BD-I, whereas a history of suicide attempts was associated with lower odds of UM (p<0.05). Conclusion: Although both groups exhibited functional impairment, patients with UM demonstrated relatively better emotional and social functioning than those with BD-I. These findings suggest that UM may be associated with a distinct functional profile, with potential implications for prognosis and treatment planning. Incorporating functional outcomes into the clinical assessment of UM may help optimize therapeutic strategies and improve long-term psychosocial outcomes.

Tütüncü, Mehmet; Yilmaz, Nazan
Accurate estimation of gravity-height gradient and plumb line curvature is fundamental for gravity field modeling, geoid determination, and high-precision geodetic applications, especially in mountainous regions. This study presents an integrated computational framework combining terrestrial gravity observations, precise leveling, GNSS measurements, and Global Geopotential Models (GGMs) to estimate and compare gravity-height gradient and plumb line curvature in the rugged terrain surrounding S & uuml;mela Monastery. Simultaneous gravity and leveling surveys were conducted during two observation periods to compute actual and normal gradient, level surface curvature, and plumb line curvature. Additionally, twelve GGMs obtained from the ICGEM service were used to derive the same parameters through spherical harmonic expansions. A comprehensive statistical evaluation, including minimum, maximum, mean, standard deviation, and RMSE, was performed to assess the consistency between terrestrial and model-based results. The results show that normal gradient and level surface curvature from GGMs generally agree well with terrestrial data, whereas larger discrepancies occur in actual gradient and plumb line curvature in areas with steep topographic gradients. CHAMP-based models demonstrate comparatively better consistency in representing plumb line curvature. The proposed framework confirms the reliability of global models at regional scales while emphasizing the importance of terrestrial data in complex topographic environments.

Günes, Mustafa
This article reads the male first-person narrators of Julian Barnes's The Sense of an Ending and The Only Story as gender microaggressors. Focusing on microaggression developed in social and feminist psychology, and on contemporary feminist philosophy's redescription of misogyny, the article argues that the rueful, self-critical retrospection these novels are usually praised for also serves as a vehicle for the quiet reproduction of patriarchal ideology. At the root of these microaggressions lies what the article terms 'frustrated entitlement', the felt grievance of someone who believes a tribute has gone unpaid. Feminist narratology supplies the analytic tools required to make this argument precise. Close reading distinguishes microaggressions performed by the younger protagonist within the storyworld from those enacted by the older narrator in the telling, and shows that both are absorbed into a rhetorical structure of 'bonding unreliability': the narrators name the gendered patterns of their own thought, and that very naming becomes the licence by which the patterns are kept in place. Set against the louder retrosexism of the postwar British male confessional novel in its more satirical and self-aggrandising mode, Barnes's decorous, retrospectively contrite narrators emerge as the most refined instance of an underexamined formal investment in contemporary British letters: the patient maintenance of patriarchal continuity through the voice of the man who is sorry.
- MakaleAçık Erişim2026Association of Serial Intra-Abdominal Pressure Measurements with Renal Outcomes and Mortality in Critically Ill Adults
Öztürk, Ayse Sari; Konur, Kamil; Kara, Ekrem
Background/Objectives: Intra-abdominal hypertension (IAH) is a common but under-recognized condition in critically ill patients and is associated with adverse outcomes, particularly acute kidney injury (AKI) and mortality. However, the prognostic value of intra-abdominal pressure (IAP) remains incompletely defined. This study aimed to evaluate the association between IAP levels and clinical outcomes, and to determine its prognostic significance in intensive care unit (ICU) patients. Methods: This prospective cohort study included adult patients admitted to the ICU between 2024 and 2025. Serial IAP measurements were performed using the transvesical method on days 0, 1, 3, 5, and 7. Demographic, clinical, and laboratory data, along with severity scores (SOFA and APACHE II), were recorded. Patients were followed for 90 days. Primary outcomes were AKI and 90-day mortality. Statistical analyses included regression models, survival analysis, and ROC curve analysis. Results: The prevalence of IAH was 54%. IAH was significantly associated with advanced age, male sex, higher body mass index, increased comorbidity burden, sepsis, positive fluid balance, and higher disease severity scores. Patients with IAH had a significantly higher frequency of AKI occurrence and increased mortality. IAP levels positively correlated with serum urea and creatinine levels. Serial IAP measurements, particularly on days 5 and 7, showed progressively improved predictive performance for mortality. Survival analysis revealed significantly reduced survival in patients with IAH. Conclusions: IAH is highly prevalent in critically ill patients and is strongly associated with renal dysfunction and mortality. Serial IAP measurements may provide useful prognostic information in critically ill patients; however, these findings require validation in larger studies.

Online gambling is a growing public health concern whose harms extend to the family, yet its familial consequences remain underexplored in contexts where gambling is illegal and extended-family ties are strong. This study examined how men who gamble online perceive gambling to affect their families in Siirt, Türkiye. Using a qualitative exploratory design, in-person semi-structured interviews with nine married or previously married men who currently or formerly gambled online (recruited via purposive and snowball sampling) were analyzed with a hybrid deductive-inductive, codebook thematic analysis (Fereday & Muir-Cochrane, 2006), informed by the six phases of Braun and Clarke (2006). Four themes were identified: entry into online gambling and the experience of addiction; the internal disintegration of the nuclear family; the household’s economic collapse and drift into crime; and the extended family, stigmatization, and the cultural framing of harm. Participants perceived gambling to erode communication and trust, dispossess the household, and displace men from the provider role, while family responses followed conventional gendered lines-disrupting the material division of roles while reactivating a traditional gender order. Distinctive contextual mechanisms emerged, including the extended family’s collective debt-clearing in exchange for religious oaths and the operation of stigma through kinship networks that threatened collective family honor. Because all participants were gamblers, the findings reflect their perceptions of family impact rather than the direct experiences of affected others. The results extend a predominantly Western evidence base and underscore the need for culturally sensitive, family-inclusive support that works with existing kinship structures while protecting those most burdened.

Ilyasoğlu, Huri; Arpa Zemzemoğlu, Tuba Eda; Arslan Burnaz, Nesibe
Purpose: There has been an increasing demand for food and beverage products enriched with bee products due to their valuable nutrients and bioactive compounds. This study was designed to assess the feasibility of enriching herbal tea infusions with bee products (honey and bee pollen), and to optimize formulation parameters using response surface methodology (RSM). Methods: The effects of the honey level of bee products (HLBP; 10–90 g/100 g) and the level of non-tea substances (LNTS; 1–5 g/100 mL) on the general acceptability, total glucose and fructose (TGF), total phenolic content (TPC), total flavonoid content (TFC), and antioxidant activity of the herbal tea infusions were investigated using RSM. Results: HLBP showed a positive impact on the general acceptability and TGF, but a negative impact on the TPC, while the LNTS had a positive impact on the TGF and TPC. At the optimized enrichment conditions, the response to honey–bee pollen differed markedly between the two matrices: linden tea demonstrated significantly higher functional enhancement (TPC, TFC, and antioxidant activity) compared to the control, whereas sage tea exhibited relatively stable functional values. Sensory responses also differed, with linden formulations showing a significant decrease in general acceptability at lower HLBP levels, while sage formulations maintained relatively stable sensory scores. Conclusion: Overall, the findings indicate that the effects of honey–bee pollen enrichment on herbal tea beverages depend on the tea matrix and require optimization, as increasing functional properties may compromise sensory acceptability, particularly in linden tea, whereas sage tea showed comparatively similar responses to the control.

Demirbağ, Orkun; Kaymak, Halil İbrahim; Alan, Hale; Akdeniz, Ferhan
In today’s dynamic business environment, organizations are increasingly investing in strategies to protect themselves against information system violations. While these technologies offer remarkable benefits—boosting efficiency, productivity, and overall performance—they also bring significant risks, particularly regarding information security breaches. This study delves into the critical connections between technostress, techno-strain, and the violation of information security policies. Our research aims to shed light on how technostress, which is commonly experienced by engineers working in technology-intensive environments within the IT sector, drives information security violations. Importantly, we will also explore how techno-strain mediates this relationship. By focusing on engineers who are consistently engaged with advanced technology, we seek to answer essential questions about their experiences. It is worth noting that the requirements for information security technology can widely vary based on factors such as industry type, organizational structure, departmental roles, and cultural norms. Therefore, this study examines how technostress increases the likelihood of information security policy violations and how techno-strain mediates this relationship. Looking ahead, future research should consider both the broader institutional contexts and the individual characteristics that may shape the relationship between information security violations and technostress. Furthermore, understanding the repercussions of information security violations—stemming from technostress—on a company’s financial health is vital for organizations aiming to safeguard their assets and maintain a competitive edge. Emphasizing these insights can lead to more effective strategies for managing both technology and talent in the workplace.
- MakaleYalnız künye2026Optimizing compton suppression systems: A parametric monte carlo study of NaI scintillator geometry
Kaya, Ali; Çelik, Necati; Kaya, Selim
Compton suppression systems are widely used to enhance gamma-ray spectral quality in applications such as nuclear safeguards and environmental radioactivity measurements. Although optimization of high-purity germanium (HPGe) detectors has been extensively reported, the geometric optimization of secondary sodium iodide [NaI(Tl)] scintillation detectors remains less studied. This work investigates the influence of annular and plug NaI(Tl) detector geometry—length, thickness, and radius—on Compton suppression performance using Monte Carlo simulations. Performance is evaluated in terms of the peak Compton suppression factor (CSFpeak) and total Compton suppression factor (CSFtotal). The results show that CSFpeak and CSFtotal increase with plug length (2–10.2 cm) and annular thickness (1–5.85 cm), with saturation observed beyond approximately 8–10 cm and 4–5 cm, respectively, due to reduced incremental photon absorption. The plug detector radius (3.72–5.1 cm) exhibits a nonlinear effect, with optimal performance achieved at 4.55–4.83 cm, beyond which gains are marginal (<5%). Suboptimal geometries (plug length <6 cm, annular thickness <3 cm, plug radius <4.28 cm) result in 20–60% lower suppression performance, increasing Compton continuum contributions in 662 keV spectra. The optimal configuration—plug length of 8–10 cm, plug radius of 4.55–4.83 cm, and annular thickness of 4–5 cm—achieves more than 90% of maximum CSFpeak and CSFtotal while maintaining a balance between performance and detector volume. These results provide quantitative design guidelines for optimizing NaI(Tl)-based Compton suppression systems for improved gamma-ray spectrometry performance.

Şimşek, Ahmet Bahadır; Göktekin, Zekiye; Şimşek, Tuğçe; Tunçer, Dilara
In workplaces, emergency teams comprised of employees play a critical role in minimising damage during emergencies through rapid response. This study introduces a multi-objective employee-team matching model that optimally assigns employees to emergency teams, balancing stakeholder preferences and physical requirements. Using a regulated many-to-one matching framework, this model accounts for employee preferences, decision-maker evaluations, and team-specific physical standards, addressing limitations in current manual matching practices. Tested through a real case study in a university setting, the model demonstrates its efficacy by achieving stable, satisfactory matches that outperform traditional methods. Sensitivity analysis across multiple scenarios further illustrates the model’s adaptability, providing decision-makers with a systematic tool for improving team stability, performance, and flexibility in various emergency preparedness contexts. The main contribution of this study is the reconciliation of preference-based assignments with performance requirements through a tuneable objective function. By jointly considering soft (preferences) and hard (physical) constraints in a single framework, the model allows decision-makers to balance satisfaction and operational feasibility–an integration that existing approaches typically overlook. This approach presents a robust, data-driven solution to enhance organisational resilience and efficiency in critical situations.

Dişli Bayraktar, Eda; Öztürk, Zeynep; Öztürk Küçük, Hilal
Artificial meat has emerged as a promising sustainable food technology with the potential to mitigate environmental impacts associated with conventional livestock production. However, its societal diffusion largely depends on consumer acceptance and the adoption of this innovation. This study examines academics’ attitudes and consumption intentions toward artificial meat in Turkey by focusing on two innovation adoption tendencies novelty seeking and independent decision making and testing the mediating role of attitude within the Theory of Planned Behavior framework. Data were collected via an online questionnaire distributed through social media and email, yielding 277 valid responses from academics across different regions and faculties. Analyses were conducted using SPSS and Hayes’ PROCESS macro (Model 4) with 5,000 bootstrap samples (95% confidence intervals). Results indicate that attitude toward artificial meat is the strongest predictor of consumption intention. Novelty seeking positively predicts attitude, which in turn increases intention; when attitude is included, the direct effect of novelty seeking on intention becomes non-significant, indicating full mediation. In contrast, independent decision-making negatively predicts attitude and indirectly reduces consumption intention through attitude, also reflecting a full mediation structure. Descriptive findings further show high awareness but low willingness to try artificial meat among academics. Overall, the study highlights the central role of attitude in the adoption of innovative food technologies and suggests that communication strategies should prioritize attitude formation, particularly by addressing skepticism among autonomous decision-makers while engaging novelty-seeking individuals as potential early adopters.

Berktaş, Serap; İncegül, Yasemin; Çam, Mustafa
Fruit bars are snack products obtained by mushing fruit, adding sugar, pectin, and other ingredients, and drying the resulting mixture. The aim of this study was to investigate the effects of spent coffee grounds (SCGs), a valuable waste product of the coffee industry, on the physicochemical and bioactive properties of a snack fruit bar enriched with bioactive properties after mushing apricot fruit. Results showed that apricot bars containing 2.5%, 5%, and 7.5% SCGs had higher phenolic, flavonoid, antioxidant activity (ABTS and DPPH), ascorbic acid, and total carotenoid contents compared to the control group. Especially, the fruit bar containing 7.5% SCG stood out in terms of tested bioactive properties. Therefore, it has been determined that the antioxidant and phenolic compounds found in SCGs are also reflected in fruit bars. Furthermore, α-amylase and lipase inhibition values were increased in the enriched fruit bars, and the potential of the developed fruit bars to exhibit antidiabetic and antiobesity properties was improved. Furthermore, the intestinal phase phenolic compound bioaccessibility values of the enriched fruit bars (87.40%–133.3%) were higher than the SCG-free control fruit bar (91.7%). The potential for creating an alternative product with improved nutritional and economic benefits by adding a waste product rich in bioactive compounds such as SCGs to the fruit bar formulation was evaluated. Such products could be considered a new alternative to a functional snack product group rich in bioactive substances that could be incorporated into today's diet.

Oruç, Abdurrahman; Cengiz, Ekrem
Background/Objectives: Measuring perceived social support after disaster remains an unresolved psychometric problem. Most instruments do not jointly capture the source of support (from whom it comes) and its function (how it operates). None has been validated in a disaster-survivor sample with retrospectively framed items. We developed and validated the Perceived Social Support in Disasters Scale (PSSDS-28), a 28-item measure integrating both dimensions. Methods: In Phase 1, a PRISMA 2020-guided systematic review; a two-round Delphi with eight experts, cognitive interviews (n = 12); and a pilot study (N = 150) produced a 31-item form. In Phase 2, face-to-face data were collected from 607 adults affected by the 6 February 2023 Kahramanmaraş earthquakes (Türkiye). Multiple analytic frameworks converged on a five-factor, 28-item structure comprising family–relative, social environment, institutional, emotional, and instrumental–informational support. Results: The correlated five-factor model fit the independent validation sample well (CFI = 0.954, RMSEA = 0.076, and SRMR = 0.072) and outperformed a one-factor alternative (ΔCFI = 0.222). Blocks showed strong internal consistency (ordinal α = 0.852–0.949), composite reliability (0.865–0.950), and adequate test–retest stability (ICC = 0.542–0.909). Scalar measurement invariance held across six groupings, with no meaningful differential item functioning. Convergent and discriminant evidence supported construct validity, and common-method variance was negligible. Institutional (M = 3.29) and instrumental–informational support (M = 2.99) scored lowest—a profile a global score would conceal. Conclusions: The PSSDS-28 provides promising initial psychometric evidence for a multidimensional post-disaster assessment instrument situated at the perceived–received interface, a target that general-purpose scales are not designed to capture. Criterion-related validity, cross-cultural validity, and cross-disaster replicability remain to be demonstrated.

Akdoğan, Arda; Baltacı, Cemalettin
In this study, non-alcoholic beer was produced with an ohmic heating-assisted vacuum distillation system (ODVD) and vacuum rotary distillation (VDD). The processes were conducted at three vacuum pressure levels (100, 150, and 200 mbar). Corresponding operating temperatures were 50, 58, and 67°C for the VDD system, while the ODVD system operated at in-situ-ohmic heating without an external heating medium. In ODVD, three voltage gradients (15, 20, and 25 V/cm) were applied. The two systems were compared in terms of processing time, energy efficiency, aroma profile, antioxidant capacity (ABTS, DPPH, TAC, FRAP), total phenolic (TPC) and total flavonoid content (TFC), vicinal diketone (VDK), pH, color, and bitterness value. The ODVD system showed significantly shorter processing times and energy efficiency than VDD. While the pH values of dealcoholized beer increased slightly compared to the original beer, color and bitterness values were higher in VDD samples. Aroma compounds such as ethyl acetate, isoamyl acetate, and ethyl caproate were lost during both processes. Overall, the findings demonstrate that ODVD is a promising and energy-efficient alternative for the production of non-alcoholic beer, with comparable product quality to VDD.

De, Prabal K.; Tümay, Muhammed
Using data from the Turkish Demographic Health Survey and a Regression Discontinuity Design, we estimate the effects of an exogenous increase in mandatory schooling on educational mobility among women in Türkiye. Our findings indicate that compulsory schooling may increase upward educational mobility where women attend education levels higher than their parents, particularly mothers. Additionally, we find such effects not only for the level at which schooling became compulsory but also at higher levels, showing a magnification of the initial impact.

Durmus, Tahsin; Coruh, Emine
Accurate perception and interpretation of the road environment are essential for safe driving. Vertical traffic signs play a key role in communicating warnings, regulations, and guidance to road users, thereby supporting safe and efficient traffic flow. However, their effectiveness depends not only on proper design and placement but also on how accurately and promptly they are perceived by drivers, which may be influenced by factors such as attention, cognitive workload, physical and mental condition, and fatigue. This study evaluates the contribution of selected vertical traffic signs to driving safety along a designated roadway section in Şanlıurfa, Türkiye. Face-to-face surveys were conducted with 480 active road users. Drivers’ knowledge, compliance behavior, safe route preferences, perceived visibility, and the effects of missing or inadequate signage were analyzed. The results indicate that driving exposure, education level, and experience significantly influence knowledge and perception of traffic signs, while compliance shows limited variation. These findings suggest that knowledge alone does not necessarily translate into behavioral compliance and underscore the importance of considering both driver-related factors and infrastructure characteristics in traffic safety strategies. The study provides practical insights for improving the visibility, placement, and overall effectiveness of vertical traffic signs in rapidly developing urban environments.
