    No full text
    Poverty is a widespread issue globally, defined as the lack of ful- fillment of basic needs. In Turkey, factors such as high inflation, de- creasing real income, economic crises, and earthquakes have contributed to an increase in poverty. Existing literature indicates that a significant portion of this increase affects women. Despite numerous studies on poverty and coping strategies, this research specifically focuses on women’s poverty. The aim of this study is to analyze master’s theses addressing women’s poverty in Turkey, examining various variables to identify research trends in this field. To achieve this, a document review was conducted, and 41 master’s theses published in the National Thesis Center of the Council of Higher Education were analyzed using a de- scriptive analysis method. The research findings indicate that women’s poverty is investigated in various universities, with the highest number of master’s theses published in 2022. The main causes of women’s pov- erty emerged as gender inequality, employment issues, lack of educa- tion, low wages, and social exclusion

    Olive oil, which is part of the Mediterranean diet, is one of the most important foods for a healthy diet. The number of countries that produce these important foods has not increased significantly over the years. However, the number of exporting countries tripled in the same period. This study aimed to predict the countries that will lead olive oil production globally between 2024 and 2027 by using the production data from the period 1961-2023. The data were analyzed using the ARMA model in the statistical program SAS. According to the results for the 10-year period of 1961-1970, there were 25-26 olive-oil-producing countries in the world. Approximately 31.26% of olive oil production was in Italy, 28.32% in Spain, 13.14% in Greece, 7.80% in Turkey, and 5.74% in Portugal. According to the average production for the period 2024-2027, it is estimated that 34 and 35 countries will produce olive oil, with 29.93%, 9.08%, 9.06%, 9.00%, and 8.90% of the world's production provided by Spain, Greece, Turkey, Morocco, and Italy, respectively. These five countries account for 65.96% of the world's production level. The estimation results of this study found that there are many exporting countries other than the leading producer countries thus showing that the producer countries do not have a forceful marketing concept, and therefore intermediaries emerge. For this reason, producer countries such as Turkey, Tunisia, and Morocco, which are not very competent in marketing, will have more say in the market by using their resources more effectively and making more effective strategies with an improved production and marketing approach

    Lisansüstü Eğitim Enstitüsü, İşletme Ana Bilim Dalı, İşletme Bilim DalıBorsa yatırım fonların performansının doğru araçlarla ölçülmesi, portföylerin optimize edilmesi ve risklerinin yönetimi açısından önemlidir. Yatırımcılar, fon yatırım araçları üzerinde yapılan performans analizleri sayesinde daha bilinçli ve verimli yatırım kararları alabilmektedir. 1960'lardan bu yana geliştirilen analiz yöntemlerinden biri olan VZA ve Malmquist endeks gibi parametrik olmayan yöntemlerin riski açıklamada daha başarılı olduğu görülmektedir. Bu çalışmada yıllık bazda aylık dalgalanma özelliğini barındıran fon araçlarının (Fon Türleri Bazında Nakit Akışı) performansını doğru araçla (VZA ve Malmquist endeks) ölçerek literatürdeki bu boşluk giderilmeye çalışılmıştır. Araştırmada güncel olan 2022 yılına ait veri kümesi (3 girdi 5 çıktı, 12 ay) üzerinde çalışılmıştır. Yapılan VZA analizini açıklamak üzere 12 çeşit standart fon türünün 12 ay boyunca aylık performansları Malmquist endeks ile ölçülmüştür. Bu iki analiz sonucunun beraber değerlendirilmesiyle yatırımcıların fon yönetimini daha az risk alarak portföylerini optimize etmelerine yardımcı olacak bir görüş ortaya konmaya çalışılmıştır. Çalışmada yıl bazındaki güncel veriler ile çalışıldığından 2022 yılı ile sınırlandırılmıştır. Araştırmacılar daha önceki yıllara ait verileri kullanarak yıllık bazda bu çalışmanın tekrarlarını yapabilecekleri gibi, yıllık dalgalanmaları da dikkate alarak daha geniş bir çalışma yapabilirler. Üç bölümden oluşan bu çalışmanın birinci bölümünde performans ile ilgili temel kavramlar verildikten sonra performans ölçüm ve modelleri tanıtılmıştır. İkinci bölümde ise çoklu girdi ve çoklu çıktı veri setlerini değerlendirmek için kullanılan matematik programlama tabanlı parametrik olmayan bir veri analizi yöntemi olan Veri zarflama analizi (VZA) tanıtılmıştır. VZA ile ilgili literatür verilerek modellerin kuramsal temeller tanıtılmıştır. Analiz bölümünü oluşturan üçüncü bölümde ise veri seti (girdi/çıktı başlıkları) ve analiz programı tanıtılarak VZA ve Malmquist endeks analizi yapılmıştır. Veriler akademik kullanıcılar için tasarlanmış ve ücretsiz olarak erişilebilen EMS (Efficiency Measurement Systems) programı ile hem VZA hem de Malmquist endeks analizi birlikte yapılmıştır. Yapılan bu çift yönlü analizler karşılaştırılarak fon türlerinin periyodik performans değerlendirmeleri ortaya konmaya çalışılmıştır. Sonuç ve önerileri kısmında ise yapılan analizlerin genel bir değerlendirmesi özet halinde verilmiştir.The performance measurement of stock investment funds with accurate tools is important for optimizing portfolios and managing risks. Through performance analyses conducted on investment fund instruments, investors are able to make more informed and efficient investment decisions. Non-parametric methods such as DEA and Malmquist index, developed since the 1960s, have been observed to be more successful in explaining risk. In this study, the performance of fund instruments containing monthly fluctuation characteristics (Cash Flow Based on Fund Types) was measured accurately with the correct tools (DEA and Malmquist index) in order to fill this gap in the literature. The study was conducted on the current dataset for the year 2022 (3 input 5 output, 12 months). To explain the DEA analysis, monthly performances of 12 standard fund types over 12 months were measured with the Malmquist index. By evaluating the results of these two analyses together, an attempt was made to present an opinion that would help investors optimize their portfolio management with less risk. Since the study used current year data, it was limited to the year 2022. Researchers can replicate this study annually using data from previous years, and can conduct a broader study taking into account annual fluctuations. The first part of this three-part study provides basic concepts related to performance, followed by the introduction of performance measurement and models. In the second part, Data Envelopment Analysis (DEA), a non-parametric data analysis method based on mathematical programming, was introduced to evaluate multi-input and multi-output data sets. The theoretical foundations of the models were introduced by providing literature related to DEA. The third part, which forms the analysis section, introduces the data set (input/output headings) and the analysis program, and VZA and Malmquist index analyses were performed. The data, designed for academic users and freely accessible through the Efficiency Measurement Systems (EMS) program, enabled both DEA and Malmquist index analyses to be conducted together. These dual analyses were compared to present periodic performance evaluations of fund types. In the conclusion and recommendations section, a summary evaluation of the analyses conducted was provided

    Today, reasons such as increasing pollution on a global extent and limited raw material resources are increasing the interest in green supply chain management (GSCM). GSCM includes the processes starting from the very beginning of the production process of a product, completing the production, delivering the product to the customer, and recycling the product at the end of its useful life. Its main purpose is to eliminate or minimize the damages caused to the environment in all of these processes. In order to achieve this goal, it has great importance to assess the suppliers, which are one of the most important components of the production process, in terms of becoming a green supplier. In this study, a fuzzy expert system model has been developed to assess the green suppliers based on green production technology, environmental management system, pollution control, product cost, quality, and lead time criteria. Mean Square Error (MSE) and coefficient of determination (R2) have been calculated to measure the performance of the developed model. These calculated values show that the green supplier assessment performance of the developed model is quite high

    Lavender honey is one of the most desirable blossom honeys for its unique taste and aromatic qualities and can vary significantly from one region to another. In this study, melissopalynological, physicochemical and antioxidant properties of lavender honey from the Isparta region of T & uuml;rkiye were investigated. The ration of the Lavandula spp. pollen were identified ranging from 9 % to 76 % in the thirteen samples. The average pH, conductivity, moisture, Hunter Lab* and proline values were 3.72, 0.22 mS/cm, 17.17 %, L*: 66.56, a*: 66.32, b*:18.41 and 576.92 mg/kg, respectively. The average F+G and F/G were 67.66 % and 1.02, respectively. The average of total phenolic (TP) and flavonoid (TF) substance were found to be 39.40 mg GAE/100 g and 3.23 mg QUE/100 g, respectively. The average total antioxidant capacity (FRAP) and DPPH radical scavenging activity values were found to be 178.28 mu mol FeSO4 & sdot; 7H(2)O/100 g and 53.09 mg/mL, respectively. In the phenolic component analysis performed with HPLC-PDA, p-OH-benzoic acid, p-coumaric acid, chrysin and pinocembrin were detected as common polyphenols in the samples. Conclusively, despite considerable variability in their monofloral characteristics, no significant differences were observed in the physicochemical and antioxidant properties of lavender honeys.We extend our gratitude to the Isparta and Burdur Beekeepers Union for supplied honey samples

It also adopted a mixed approach that used quantitative and qualitative data together. The study group consisted of 99 students (40 in 5th grade and 59 in 7th grade, respectively) enrolled in a secondary school in Ankara during the 2022-2023 academic year. The quantitative dimension of the study involved the classes as randomly selected experimental and control groups. The experimental groups of 5th and 7th grades received the Social Studies courses designed by the FLM teaching model within the scheduled time intervals. However, the control groups of 5th and 7th grades received lessons with the traditional teaching approach. The study utilized academic achievement tests and semi-structured student interview forms as data collection tools. The collected study data were analyzed using the paired sample t-test and unpaired t-test through the SPSS software. The qualitative dimension of the study, on the other hand, involved the content analysis of the data collected through semi-structured student interview forms. Considering the quantitative findings, the study revealed no statistically significant difference between the 5th-grade experimental and control groups for academic achievement and permanence learning mean scores. However, the study found significant results in favor of the experimental group between the 7th-grade experimental and control groups for academic achievements and permanent learning. According to the qualitative findings of the study, however, the majority of the students at both grade levels stated that the FLM model contributed to their learning. Furthermore, while the 7th-grade students expressed that the FLM model made their learning permanent, they also suggested its widespread use in other branch courses and its application throughout the entire semester

    Enhanced thermal and angular velocity-induced hybrid piezoelectric energy harvesting of smart turbine blades

    No full text
    In this study, an approach is proposed to examine hybrid piezoelectric energy harvesting performances from vibrations induced by thermal and angular velocity loads in order to generate energy from the smart turbine blade. In the proposed method, a smart turbine blade is formed by patching the piezoelectric material to the root surface of the turbine blade. A finite element (FE) model of the smart turbine blade is established and then it is validated with a smart blade model in a reference study to test the reliability and accuracy of the FE method. The defined loads are applied to the smart blade to obtain energy from mechanical vibrations induced by thermal and angular velocity loads. Temperature distribution, voltage, and vibration results obtained from energy harvesting analysis under different thermal and angular velocity loads are presented. In order to investigate the energy conversion efficiency of the energy obtained from the system, the energy harvesting circuit is tested in terms of battery discharge times and power output values. The results show that while the maximum energy conversion in the thermally induced smart turbine blade is 11.9 W, a power output of 12.3 W is obtained from the hybrid energy harvesting mechanism under angular velocity and heat flux loads

    No full text
    Objective: In this study, we aimed to examine the healing trend of hepatic encephalopathy after transplantation surgery in patients with liver failure. Method: We conducted this descriptive and cross-sectional study with the participation of liver transplant recipients. A personal information form, the West Haven Criteria (WHC), the Warwick-Edinburgh Mental Well-Being Scale (WEMWBS), and the Richmond Agitation Sedation Scale (RASS) were used for data collection. The data were analyzed using Chi-squared tests, ANOVA, and paired-samples t-tests. Results: As time progressed after liver transplantation, hepatic encephalopathy stages regressed (p < 0.01). We found that liver transplant recipients with end-stage hepatic encephalopathy were mostly within the first 6 months after transplantation, while patients with first-stage hepatic encephalopathy had received liver transplants more than 2 years ago (p < 0.01). Conclusions: The results of our study revealed that hepatic encephalopathy stages regressed after transplantation, but there was no complete recovery. This highlights the need to develop new treatment strategies other than liver transplantation for the treatment of hepatic encephalopathy
