Acar, Sedat
The labour market engagement of women in traditionally oriented societies is frequently constrained by their husbands’ socioeconomic resources. The rise in women’s educational attainment plays a pivotal role in reshaping the gender-based division of labour and enhancing their labour force participation. Drawing on nationally representative cross-sectional data from the Turkish Income and Living Conditions Survey (2006–2022; N = 136,874), this study examines the moderating role of wives’ educational attainment in the association between husbands’ socioeconomic resources (income and education) and wives’ labour force participation. The interaction model reveals that the probability of labour force participation is higher for wives with university-educated husbands only among those who are university-educated themselves; in contrast, participation rates decline for non-university-educated wives. Among university-educated wives, labour force participation is markedly higher in educationally homogamous marriages than in hypogamous marriages. While the negative income effect attributed to husbands persists across both educational strata of wives, its magnitude is significantly attenuated among university-educated wives. These findings indicate that in Turkey, a university degree serves as a critical mechanism for married women to circumvent economic and cultural barriers to labour force participation, with homogamous marital unions further facilitating their engagement.

Yucesan, Melih; Pekel, Engin; Celik, Erkan; Gul, Muhammet; Serin, Faruk
An effective short-term natural gas forecasting method contributes to social contributions and allows industrial chain elements to function effectively and minimize economic losses. We dealt with a comparative framework on the applicability of different methods in daily natural gas service (NGS) consumption forecasting. In this context, time series, machine learning, evolutionary and population-based approaches, and their hybrid versions are applied to the NGS data. Hybridized approaches are tested in the scope of NGS consumption forecasting for the first time in the literature in this study. The case of Turkey is handled, and its NGS data is used to demonstrate the comparative framework’s applicability. The comparative study is assessed in the lights of common forecasting accuracy measures of mean absolute percentage error (MAPE), R-squared (R2), and mean squared error (MSE). According to each method’s results, the seasonal autoregressive integrated moving average with exogenous regressors (SARIMAX) and artificial neural network (ANN) hybrid model provides the most dominant performance with respect to MAPE. The lowest error was obtained with a MAPE value of 0.357 in this hybrid model constructed under seven neurons in its ANN structure. This model is followed by another hybrid model, autoregressive integrated moving average (ARIMA)-ANN, with a MAPE value of 0.5 under nine neurons in terms of accuracy performance. The worst performance value belongs to the Genetic algorithm-ANN hybrid model with a MAPE value of approximately 26%.

Gücer, Mehmet Ali; Delimehmet, Zeynep; Çimen, Okay
Middle-Late Carboniferousgranitic rocks are widely observed in larger outcrops in the Eastern Pontide orogenic belt of the Eastern Sakarya Zone. This tectonic belt is an important part of the Anatolian plate in terms of containing igneous rocks with a wide age and composition range. This study presents new petrochemical-petrological data on Carboniferous granites in the G & uuml;neydere and surrounding area of Bayburt (NE Turkey). The granitic rocks, which include an area of approximately 5 km, represent the pre-Jurassic basement in the study area. Besides, they are unconformably overlain by Early- Middle Jurassic volcano-clastics units and Late Jurassic- Early Cretaceous limestones. They mainly consist ofgranite, granite porphyry and aplite, to a lesser extent granodiorite and quartz monzonite. Rocks have high SiO2 contents (60.43-75.51%) and high K calc-alkali to shoshonitic affinities and have been derived from an I-type source. The granitic rocks are metalumine-peralumine in character and are similar to postcollisional volcanic arc granitoids. Whole-rocks major and trace element trends show that plagioclase, hornblende, biotite, apatite, and Fe-Ti oxide mineral fractionations play an important role in the formation of the rocks. It has been revealed that fractional crystallization and assimilation+magma mixing processes play a role in the development of granites. Also, the saturation temperatures calculated from the whole-rock zircon values reflect lower initial magma temperatures. All results obtained indicate that parental magma of studied granitic rocks have evolved from lower/middle crust- derived melts as a result of partial melting and differentiated and emplaced in the continental magma chamber.

This study examined certain water quality parameters and zooplankton fauna at two stations in Halbori Springs (Tunceli, Turkey), over a 12-month period from June 2022 to May 2023. The highest water temperature of 15.4°C was recorded at Station 2 in August, while the lowest water temperature of 5.0°C was recorded at Station 2 in January. The pH value of Halbori Springs ranged from 6.4 to 8.5. Dissolved oxygen varied between 8.1 and 11.9 mg/L during the study period. A total of 26 zooplankton species were identified in Halbori Springs. Nineteen of these species belong to Rotifera, five Cladocera and two Copepoda. According to the index analysis results of Station 1, the month with the highest species richness index, as measured by the Shannon Wiener H′ index, was October with a value of 1.97, while the lowest value was 0.45 in January. The highest value for the Margalef species diversity D index was 0.78 in October, and the lowest was 0.12 in January. According to the index analysis results of the station 2, the month with the highest species richness index, Shannon Wiener H’, was September with a value of 1.68, while the lowest value was observed in January with 0.67. As for the Margalef species diversity index D, the highest value was recorded in September with 0.64, and the lowest value was observed in January with 0.12. In Halbori Springs, 1 species of Brachionus and 2 species of Trichocerca were found. The QB/T ratio was calculated to be 0.5, suggesting that the study area has oligotrophic characteristics.

Kervankiran, Ismail; Sert Eteman, Fatma
Interregional development disparities have emerged as one of the most controversial issues in contemporary discourse. Across the globe, disparities in various facets, including social, cultural, tourism, and economic dimensions, are strikingly evident. Turkey, a nation renowned for its importance in the global tourism landscape, is no exception to this phenomenon. The spatial distribution of tourism development in Turkey reveals an inequality. This study aims to examine the variations in interregional tourism development by establishing a comprehensive tourism development index for Turkish cities and subsequently categorizing them based on their distinctive levels of development. To achieve this, a dataset consisting of 18 variables from various public institutions in the year 2017 was compiled. With this data set, Principal Component Analysis was employed to compute the tourism development index for each city, and the Hierarchical Cluster Method was used to categorize cities into distinct development categories. In conclusion, the research underscores the influence of both policy interventions, planning, and the intrinsic characteristics of cities in shaping the spatial disparities in tourism development within Turkey. The implementation of neoliberal policies has notably concentrated capital, investments, and the tourism market in the Mediterranean and Aegean coastal regions, exacerbating spatial inequality in tourism. The implications of this study hold the potential to guide policymakers in narrowing the gaps in interregional tourism development within Turkey, thereby fostering a more equitable and sustainable future.

Aykac, Yunus Emre; Yucesan, Melih; Gul, Muhammet
Solar energy stands out with its increasing potential in the world. The decision to choose the location of a solar power plant is very important due to the investment return. In this study, a solar power plant site selection for Tunceli, Turkey is studied with a two-stage multi-criteria decision-making approach. In the first stage, the importance levels of the determined nine factors are obtained by the best-worst method (BWM). In the second stage, the most appropriate site is selected among the eight districts of Tunceli. As a result of the first stage, solar and fault line emerged as the most and least important factor, respectively. The second stage showed that Pertek district is the most suitable place. A comparative framework has been created including five different MCDM methods, which strengthens the final decision's accuracy and reveals whether each method's results are correlated.

This study performed statistical analyses based on chromosome micromor-phology of 18 Centaurea taxa, two of which are endemic. ANOVA, Correlation analy-sis, Discriminant analysis and Cluster analysis were performed to determine the relationships between taxa based on chromosomal features. In addition, according to the data obtained from these analyses, the relationships between taxa and sections were tried to be interpreted. As a result of the analyses, the taxa C. drabifolia Sm. floccosa (Boiss.) Wagenitz & Greuter, C. kotschyi (Boiss. & Heldr.) Hayek var. floccosa (Boiss.) Wagenitz and C. behen L. and C. polypodiifolia Boiss pseudobehen (Boiss.) Wagen-itz were located close to each other. These taxa are located in the same sections in the morphological classification. Besides, in the Discriminant analysis, the taxa of Acrocen-tron, Microlophus, Cheirolepis sections were closely located compared to all other taxa. However, results were not seen to cover all taxa of the sections. This study revealed various chromosomal characteristics of some Centaurea taxa distributed in the Eastern Anatolia. It also performed statistical analyses on these data. While determining the relationships between taxa according to chromosomal characteristics, comparing chromosomal formulas and indices collectively and evaluating the relationships was found to be relatively consistent with morphological classification.

Medicinal plants have been used by humans for the treatment of various diseases for thousands of years from past to present. Members of the Lamiaceae family are among the most preferred medicinal plants due to the wide variety of secondary components they contain, particularly essential oils. In this review, Master’s and PhD theses and books based on ethnobotanical studies investigated between 1960 and 2021 as well as internationally recognized databases (PubMed, Scopus, Google Scholar, Web of Science, SciFinder, Springer and Elsevier) were used to determine the medicinal uses of Lamiaceae taxa among the people in Turkey. As a result of the study, it was found that a total of 221 taxa (192 species) belonging to 29 genera, 51 of which are endemic, have medicinal/therapeutic uses. The local names of these taxa, the usage which are used among the people, the diseases in which they are used, and the geographical regions given in the present study. The genera of taxa most commonly used for medicinal purposes by the local people are Salvia (37 taxa), Sideritis (25 taxa), Stachys (22 taxa), Thymus (16 taxa) and Origanum (13 taxa). It was observed that the most frequently used two methods while preparing these plants for use was infusion (61%), and decoction (24%). Studies conducted on National (TURK, BHP), Regional (EU) and International Pharmacopoeias (WHO) and various monographs (AHP, COMISSION E, EMA, ESCOP, PDR) have revealed that there are 29 taxa included in these pharmacopoeias and monographs whose purpose of use are similar to the diseases that local people are trying to treat. Diseases that people use plants for therapeutic purposes are grouped into 12 categories. It was determined that these plants were widely used for therapeutic purposes in gastric disorders as well as otolaryngology and respiratory system diseases. This review briefly discusses whether some taxa commonly used by the local people in the treatment of diseases can be useful in the treatment of the disease in question, in the light of scientific studies.

Ezer, Tülay; Alataş, Mevlüt; Batan, Nevzat; Erata, Hüseyin
In this study, the epiphytic bryophyte succession of Picea orientalis forests on the Kümbet High Plateau (Giresun-Turkey) were studied. A total of 21 epiphytic bryophyte species were determined (16 mosses and 5 liverworts). The epiphytic bryophyte communities were sampled in 60 sample plots taken from the trunks of Picea orientalis, each of which was 20 × 20 cm in size. The Index of Ecological Significance (IES), based on a combination of the relative frequency and mean cover of epiphytic bryophytes, was used to evaluate the abundance of bryophyte communities in epiphytic habitats on the tree trunks. In addition, multivariate classification techniques (TWINSPAN and DECORANA) were used to classify the community structures in successional stages. TWINSPAN divided the 60 sample plots into two main groups: a) the lower base communities (LB) and b) the middleupper zone communities (MU). Moreover, the middle-upper zone communities (MU) were divided into two sub-groups associated with the successional gradient (MU1 and MU2). DECORANA classified these communities along the ordination axes 1 and 3 related to the height gradient of Picea orientalis and the moisture (from mesic to xeric) gradient of the epiphytic habitat. While Exsertotheca crispa, Cynodontium fallax, Lewinskya striata, and Habrodon perpusillus were only found on old spruce trees, Drepanium fastigiatum was only found on young trees and Lophocolea heterophylla was only found on middle-aged trees.

There are a very limited number of studies on plants traditionally used in animal diseases in Turkey. As a result, valuable information is getting lost. Traditional plant use in Genç District (Turkey) was recorded by semi-structured interviews with breeders and shepherds. The collected information was subjected to quantitative analysis using the informant consensus factor. It was recorded that a total of 53 plants from 24 families were used in the traditional treatment of animal diseases. 8 of these plants are endemic plants with a narrow distribution area and were recorded for the first time by us. The breeders stated that they applied such plants to animals with peace in mind as these plants had been used for human treatment as well. This study is the first ethnoveterinary study conducted in the province. Phytochemical studies need to be carried out on medicinal plants used in livestock around Bingöl Province. We believe that the use of this preliminary information obtained from ethnoveterinary studies by researchers will contribute to the production of natural animal medicines.

Objective: This study was conducted to assess the relationship between the symptoms experienced by women with COPD and the quality of their sexual life. Method: This study was designed as a descriptive cross-sectional study. The study was conducted at a hospital’s chest diseases clinic located in the western of Turkey. The sample comprises 62 female patients hospitalized with diagnosis of COPD. A questionnaire form, the Medical Research Council Scale (MRCS), the COPD Assessment Test (CAT) and the Sexual Quality of Life-Female (SQOL-F) applied to the women with COPD. Frequency, percentage, mean, standard deviation, Kruskal Wallis test, Mann-Whitney U Test, correlation and regression analysis, were used for the data analysis process. Findings: The decrease in the education level of the participants who have any accompanying chronic disease, and experience symptoms during sexual intercourse negatively affects their quality of sexual life. The quality of sexual life decreases as age, duration of marriage and duration of illness increase (p < 0.05). The results of the linear regression analysis carried out to predict the quality of sexual life of women with COPD shown that the increase in mMRC and CAT significantly decreased the quality of sexual life. These variables explain 58% of the variance. Conclusions: The result of the study shown the sexual quality of life of women with COPD was impaired and COPD symptoms affect them.

Yazici, Muge; Zabci, Cengiz; Natal'in, Boris A.; Sançar, Taylan; Akyuz, H. Serdar
The Ovacik Fault (OF) is one of the internal structures of the Anatolian Block, located close to its eastern boundary. Although it shows a very clear surface trace, there are no instrumentally recorded surface rupturing earthquakes on this fault. This study concludes results of the first palaeoseismological trench study on the OF with the evidence for three surface rupturing earthquakes for the last 6 kyr. Structural, stratigraphical and geochronological constraints show that the oldest event happened between 4700 and 3022 BCE, whereas the penultimate event was between 2262 and 1643 BCE. The youngest event happened after 56 BCE, which we could only delimit from below because of the absence of any dateable material from the upper layers of the relevant horizons. The derived mean interevent time of these three palaeoevents is 2400 +/- 765 years. We could not correlate any of these palaeoevents with historical earthquakes due to the absence of records in catalogues for the region of interest. Moreover, we used cumulative offsets of the major drainages to calculate the long-term slip rate of 2.7 mm/year since the Pliocene, which exceeds slip rates of other internal faults of Anatolia almost by the factor of two. Our results do not only show significant deformation for the internal parts of Anatolia but also point out a seismic potential of the OF.

In this study, three hybrids of Origanum (Lamiaceae) were examined in detail using morphological, karyological, palynological and molecular approaches. One of the three hybrids, O. × aytacii, is here described for the first time, and is compared with its putative parents, O. sipyleum and O. vulgare subsp. hirtum. In addition to morphological, karyological and palynological features, we also examined nuclear ribosomal DNA (ITS) sequences of O. × intermedium (O. onites × O. sipyleum), O. × intercedens (O. onites × O. vulgare subsp. hirtum) and their purported parental species that share the same area with the new hybrid. Pollen grains were hexacolpate and isopolar. The range of Polar/Equatorial ratio (P/E) of pollen for investigated taxa varied from 0.74 to 0.99. All investigated taxa are diploid with a chromosome number as 2n = 30. According to molecular results, O. × aytacii was the most polymorphic taxon. In addition, DNA sequences showed that O. × intercedens was more similar to O. vulgare subsp. hirtum than to O. onites, and O. × intermedium was more similar to O. onites than to O. sipyleum. Furthermore, O. onites and O. vulgare subsp. hirtum have many different ITS haplotypes, probably resulting from backcrossing with different individuals. Results obtained in this study demonstrate that hybridization has played a major role in the process of Origanum speciation.
