From best tourism village to regional development: the power of destination image in an old Greek town Mustafapasa
(2026) Yapıcı, Olcay Özılık; Gök, Hatice Sarı; Karakuş, Yusuf
This study examines the role of Perceived Value Theory and its potential for regional development in the context Mustafapasa, Turkey, which was selected as a Best Tourism Village (BTV) by UNWTO. Using a two-stage research design, the study first conducted a content analysis of 24 documents to identify the perceived image of Mustafapasa, followed by interviews with 13 participants to identify the key components of destination image. These components: history and culture, natural environment, social atmosphere and tourism activities were then compared with the sustainability goals of the BTV. The research highlights the partial achievement of these goals and emphasizes the need for greater local awareness and cooperation. The importance of this study lies in its contribution to Perceived Value Theory by demonstrating its application to rural tourism development. The findings suggest that increasing the perceived value of destinations such as Mustafapasa through strategic management can stimulate tourism, promote sustainable development and protect cultural and natural resources.

Investigation of antioxidant properties of propolis products collected from different regions
(Multidisciplinary Digital Publishing Institute (MDPI), 2026) Çetin, Aynur; Bakır, Sena; Özdal, Tuğba; Çapanoğlu, Esra
Propolis, a sticky bee hive product collected from resinous plant sources by Apis mellifera bees, exhibits a wide range of biological and pharmacological properties, primarily attributed to its rich composition of bioactive constituents, including phenolic acids, esters, and flavonoids. In this study, the antioxidant properties of 76 liquid propolis solutions from 18 different countries were investigated based on their dry matter, total phenolic and total flavonoid contents, antioxidant capacities, and phenolic profiles. The antioxidant activities of propolis from various geographic regions, including Latvia, Croatia, New Zealand, San Marino, Russia, France, Romania, Italy, Estonia, Brazil, Belgium, Germany, Slovenia, Japan, the United States of America (USA), the United Arab Emirates (UAE), Spain, and Korea, were compared. Total phenolic and flavonoid contents, as well as total antioxidant capacity (Cupric Reducing Antioxidant Capacity-CUPRAC method), were analyzed by spectrophotometry, and the major constituents were investigated by liquid chromatography-mass spectrometry (LC-MS/MS). Antioxidant test results indicated that 29 products scored below 10 mg Trolox equivalent (TE)/mL, and only 14 were scored above 100 mg TE/mL. The results showed that the total phenolic content of the samples ranged from 0.1 to 107.5 mg Gallic acid equivalent (GAE)/mL, while total flavonoid content varied between 0.1 and 174.5 mg Catechin equivalent (CE)/mL. Based on the CUPRAC assay, total antioxidant capacity values ranged from 0.1 to 492.3 mg TE/mL. Among the 76 analyzed samples, nine products exhibited antioxidant capacity values exceeding 150 mg TE/mL. In all of these samples, phenolic profiling confirmed the presence of propolis, and the analytical results were consistent with the information declared on the product labels. Hence, this study provides a comprehensive, real-market evaluation of commercial propolis products by integrating spectrophotometric assays with LC-MS-based targeted metabolomics profiling, highlighting formulation- and product type-driven differences in phenolic composition and antioxidant capacity beyond geographical origin.
The multidimensional existential meaning scale: turkish validity and reliability study
(Atatürk Üniversitesi, 2025) Vural, Muhammet Enes
Once meaning in life began to be examined on the basis of individual experience in psychology, it became one of the field's core research topics. A substantial portion of this effort-particularly since the second half of the twentieth century-has proceeded within studies aiming to measure and delineate its dimensions. Recent research has proposed that meaning comprises three fundamental components: comprehension, purpose, and mattering. Building on this theoretical background, the present study aimed to adapt the Multidimensional Existential Meaning Scale (MEMS) into Turkish and to conduct its validity and reliability analyses. In line with this aim, data were collected online, and the study was carried out with three distinct cohorts: linguistic equivalence (n = 30), test-retest (n = 64), and the main sample (n = 312). Within the linguistic equivalence phase, semantic equivalence between the English and Turkish versions was established. To test construct validity, confirmatory factor analysis (CFA) was performed, and the three-component structure of the scale was confirmed. The MEMS showed positive, significant associations with presence of meaning and with theoreti-cally related variables-life satisfaction, happiness, and religiosity-supporting convergent validity. Regarding reliability, the test-retest method indicated high temporal stability, and Cronbach's alpha for the overall scale was calculated as alpha = .96. Corrected item-total correlations further indicated high internal consistency. Overall, the findings show that the Turkish version of the MEMS, comp-rising comprehension, purpose, and mattering, exhibits strong psychometric properties and can be used with confidence to assess individuals' levels of meaning in clinical screening and psychological counseling, in mental health research, and in spiritual care services.
