Saria, Busra; Ozyurt, Emre
This paper presents results of numerical studies completed on unreinforced and doubler plate reinforced Elliptical Hollow Section (EHS) T-joints subjected to axial compressive loading on the brace member. Non-linear finite element (FE) models were developed using the finite element code, ABAQUS. Available test data in literature was used to validate the FE models. Subsequently, a parametric study was carried out to investigate the effects of various geometrical parameters of main members and reinforcement plates on the ultimate capacity of reinforced EHS T-joints. The parametric study found that the reinforcing plate significantly increases the ultimate capacity of EHS T-joints up to twice the capacity of the corresponding unreinforced joint. The thickness and length of the reinforcing plate have a positive effect on the ultimate capacity of Type 1 joints. This study, however, found that the capacity of Type 1 orientation is not dependent on the brace-to-chord diameter ratio. As for type 2 orientations, the thickness and length of the reinforcement have a minimal effect on the ultimate capacity. A new design method is introduced to predict the capacity of the reinforced EHS T-joints Type 1 and 2 based on the multiple linear regression analyses.

Başoğlu, Mustafa Engin
Maximum power point tracking (MPPT) procedure in photovoltaic (PV) systems can be realized with many different methods. Especially in arrays consisting of PV modules (PVMs) connected in series; the maximum power point (MPP) may change due to partial shading conditions (PSC), aging, degradation, fabrication production differences etc. In addition, even in small power systems containing a single PVM, the difference in shading and irradiation between submodules affects the maximum power potential of the PVM. In this study, power electronics-based power processing methods in distributed MPPT (DMPPT) systems are emphasized. Power electronics-based hardware MPPT solutions are examined in two groups as full power processing (FPP) and differential power processing (DPP). In addition, commercially available power optimizers have been examined under many criteria. The literature on the subject has been analyzed in a broad perspective, and it has been comprehensively evaluated according to criteria such as power processing level, converter configuration, MPPT algorithm, MPPT application level and control approaches. This study is an important guide for scientists and hardware engineers doing academic studies on the subject. This study, which examines the topologies and control approaches used in application-oriented studies, has the feature of triggering future studies. The features that commercial power optimizers should have and the examination of the products in the market within the framework of some criteria is one of the original aspects of the study. It is expected that this study will contribute to the PV industry in building applied and building integrated studies, where extreme shading scenario occurs.

Selecting the best supplier emerges as a crucial subject for all sectors to achieve long term collaborations in supply chains. This study object to select the most suitable supplier for a company engage in activities in the automotive supply industry. For this purpose, a five-stage Intuitionistic Fuzzy Multi-Criteria Decision Making (IFMCDM) model is conducted. Firstly, decision criteria are defined by literature research and expert group opinions. Secondly, the importance weights of these criteria are obtained by IF Decision Making Trial and Evaluation Laboratory (IFDEMATEL). Followingly, the most suitable supplier is assessed by IF Technique for Order Preference by Similarity to Ideal Solution (IFTOPSIS). In the fourth stage, Sensitivity Analysis is utilized to analyze the effect of differentiation in criterion. Lastly, a comparative analysis is carried out. The results of the study has pointed that “Price” is the most important criterion in supplier selection and “Supplier 4” is the best alternative for this case. Main contribution of this study is to integrate IFDEMATEL-IFTOPSIS method for the first time in automotive supplier selection literature and propose a specific decision framework. In addition, proposed model is found robust and valid.

Erol, Ismail; Murat Ar, Ilker; Peker, Iskender; Searcy, Cory
Despite its clear potential to contribute to sustainability, there are many challenges to adopting circular economy (CE). These barriers impede the implementation of CE; however, research to address them is ongoing. For example, novel technologies have become a key enabler for easing the impact of CE adoption barriers. Blockchain is one disruptive technology that has the potential to address some of those barriers, notably technological, organizational, and ecological. Blockchain is particularly well suited to help address supply chain-oriented barriers to CE adoption. However, a review of the literature shows that while there are a limited number of conceptual studies that address the capabilities of blockchain to alleviate the impact of the barriers to CE, no previous study has focused on this vital subject using a decision tool based on expert data. To this end, this paper proposes an integrated decision framework involving Multi-Criteria Decision-Making (MCDM)-based Quality Function Deployment (QFD) method with Hesitant Fuzzy Linguistic Term Sets (HFLTS) to investigate the true potential of blockchain to address the CE adoption barriers. Our findings indicate that enhanced supply chain traceability management, improved collaboration and coordination in supply chain ecosystems, building higher levels of trust in supply chain ecosystems, and enhanced business models are the most significant functions of blockchain to help overcome the CE adoption barriers.

Çelik, Necati; Ünal, Nüket
In quantum teleportation, the sender must interact her/his qubit to one of the qubits in a maximally entangled Bell/Bell-type state and as a result, a joint state is obtained. This joint state has to be rearranged in terms of the appropriate number of Bell/Bell-type states. Then the sender measures her/his qubits and sends the results via a classical channel to the receiver. According to the outcome of the measurement results, the receiver applies appropriate gates to the qubits in her/his share to recover the teleported state. Perhaps the most important step in this protocol is to be able to rewrite the joint state in terms of the appropriate number of Bell-type states. An efficient way to produce Bell-type states for quantum teleportation of an arbitrary n-qubit state is proposed. Quantum teleportation of an arbitrary three-qubit state is studied as an example.

Karsli, Orhan; Şengün, Fırat; Santos, José Francisco; Uysal, İbrahim; Dokuz, Abdurrahman; Aydin, Faruk; Kandemir, Raif
The Mesozoic geodynamic evolution of the Paleotethys Ocean is critical but a poorly known piece of the geological history of the Sakarya Zone, north Turkey. Here, we describe new integrated research of zircon U-Pb geochronology, bulk-rock major-trace element and Sr–Nd isotopes as well as Hf isotope of zircons from the granitic rocks of the Demirköy and Kızıldamlar plutons located in Bilecik area along the western Sakarya Zone, northwestern Turkey. Zircon U–Pb ages obtained by LA-ICP-MS reveal that the granitic magma intruded into the basement rocks during the Late Jurassic (ca. 162–157 Ma). The granites are tholeiitic and show slightly metaluminous to peraluminous geochemical affinities. The granite samples are adakitic, having relatively high Na2O (6.35–7.58 wt%) and Sr (172–580 ppm), and low K2O (0.39–1.13 wt%) and Y (3.2–5.3 ppm), and thus have high Sr/Y (70–250). The samples exhibit enrichment of light rare earth elements (REE) and large ion lithophile elements (LILE) and depletion in heavy REE and the high field strength elements (HFSE; e.g., Nb, Ti, Ta). The samples possess low 87Sr/86Sr(t) values of 0.70313 to 0.70372, and εNd(t) of −0.66 to +9.24. Zircon grains exhibit positive εHf (t) values of 5.0 to 12.8 and depleted mantle model ages of Hf (TDM1 = 0.24 to 0.68 Ga). These geochemical features and Sr–Nd–Hf radiogenic isotope systematics reveal that the adakitic rocks were likely formed by low degree melting (<10%) of the eclogitic part of an oceanic slab and subsequent melt fractionation and crustal contamination. An ongoing subduction scenario cannot explain the formation of the investigated adakitic rocks. We suggest that the adakitic plutons were generated through slab break-off after the final closure of the Paleotethys Ocean throughout the Late Jurassic (ca. 162–157 Ma). Considering the previous data, the continental back-arc basin system, leading to the opening of Neotethys Ocean at the southern margin of the continent, has been put forward to decipher the Late Jurassic tectonic evolution of the Paleotethys Ocean and the western Sakarya Zone.

Karapınar Kocağ, Esra; Li, Yutong; Popescu, Cristina Raluca Gh.
Movements of labor across the world is an ongoing debate in the literature in terms of its drivers and results in sending and receiving areas. Skill composition of immigrant labor has been discussed by several papers, although they generally focused on visa policies or firm level productivity. However, this paper focuses on the relationship between immigrants’ educational attainment and government budgeting on research and development (R&D). Panel data analysis is applied for European countries, along with instrumental variable approach as a robustness check. Findings reveal that higher budget allocation for R&D is associated with higher skill level of immigrants within overall immigrant population. This finding is driven by young immigrants whose ages are between 25 and 34 and female immigrants in these countries, suggesting that this relationship varies among sub-groups of immigrants, which would have significant policy implications. Hence, the novel and original approach of the paper resides in the deciding factors of immigrants’ skill composition.

Demirbaǧ, Orkun; Demirbaǧ, Kübra Simşek; Batl, Gülgönül Bozoǧlu
Purpose: Because of the growing interest in the literature in education and political skill as facilitators of firm performance, this article aims to reveal whether there is a moderating role of women entrepreneurs' political skill on the relationship between their education level and firm performance when firm- and entrepreneur-level characteristics remain under control. Methodology: The study was conducted in Istanbul, Kocaeli, and Bursa, cities with the lowest gender gap in Turkey. The participants of the questionnaires were 291 entrepreneurs who are members of the Women Entrepreneurs Association of Turkey (KAGIDER), the Women Entrepreneur Members of Endeavor Turkey, and the TOBB Women Entrepreneurs. Hierarchical regression analysis was performed to analyze the dataset. Findings: When firm- and the entrepreneur-level characteristics remain under control, women entrepreneurs' political skill shows a moderator role in the relationship between women entrepreneurs' education level and firm performance. Practical Implications: A bachelor's degree or higher, along with political skill, allow women entrepreneurs to increase their firm performance. Furthermore, the higher the political skill, the higher the effect of education level on firm performance. Originality/Value: This is the first study to investigate the moderating role of political skill of women entrepreneurs in the relationship between education level and firm performance. Moreover, political influence and human capital theories are jointly applied to the theoretical model.

Evren, Emine Şimşek; Celil Çakıcı, A.
Long-termed continuance of employees in hotel enterprises, especially in kitchen department where standard production is of utmost importance, is critical for organizational success. At this point, how institutionalization, a phenomenon that is usually associated with standardization, effects the organizational commitment (OC) is an important question. Another important question is how commitment to an impressive supervisor such as the chef mediates the relationship between institutionalization and OC in institutionalized hotels where standards become important instead of personal approaches. In this context, the relationship between institutionalization, OC, and commitment to the supervisor (CS), which has not been studied before, has been examined within the framework of hotel businesses. The data were collected with an online survey. The sample consisted of the kitchen staff of a national hotel chain in Turkey. The findings demonstrated that the effects of institutionalization on OC and CS were significant. CS partially mediates the relationship between institutionalization and OC. When considered within the scope of the dimensions, the CS has a partial mediating effect on the relationship between cultural power and all three dimensions of OC (affective, continuance, normative). The effect of formalization and professionalization on affective and normative commitment is partially mediated by CS.

Karabi̇Naoğlu, Murat Salim; Çakir, Bekir; Başoğlu, Mustafa Engin; Kazdaloğlu, Abdülvehhab; Güneroğlu, Aziz
Solar energy systems (SES) and photovoltaic (PV) modules should be operated at the maximum power point (MPP) to achieve the highest efficiency in the energy generation processes. Maximum power point tracking (MPPT) applications using conventional methods may not be able to follow the global MPP (GMPP) of the PV system under changing atmospheric conditions and they could oscillate around the local MPP. In this study, a machine learning and deep learning (DL) based long short-term memory (LSTM) model is proposed as an innovative solution for MPPT. Contrary to the traditional MPPT applications using current and voltage sensors, the output resistance of the PV module estimation was made by using environmental parameters (such as temperature and radiation) and artificial intelligence algorithms in this study.The LSTM model was compared with artificial neural networks (ANN) and regression methods regarding mean square error (MSE), root mean square error(RMSE) and mean absolute error (MAE) parameters. It has been determined that the LSTM model has a better performance and could more successfully follow MPP compared to the other methods. Finally, after the comparison with the ANN method, it is proved that LSTM gives 37%, 21%, and 31% more successful MSE, RMSE, and MAE results, respectively.

This study aims to evaluate the chemical composition and antimicrobial (antibacterial and antifungal) properties of the essential oil subtracted from the oleoresins, which were obtained from the stem of the Picea orientalis naturally grown in Turkey. The essential oil of the resin was obtained through the hydrodistillation method in a Clevenger type device, and it was analyzed with GC-MS/FID. The structure of 74 compounds that were found in the essential oil was elucidated by comparing with literature data and the database in the appliance. Limonene (53.40%), β-pinene (20.74%) and α-pinene (14.51%) were determined to be the major components. The highest class of compounds in resin essential oils was identified as monoterpene hydrocarbons. The antimicrobial activity of the essential oil was investigated with the agar well diffusion method against 25 microorganisms, including 13 gram-negative, 7 gram-positive bacteria and 5 yeast-molds. As the results of the analysis, the highest antibacterial activity was recorded against S. typhimurium from gram-negative bacteria with inhibition zone ranging as (13.70±0.10-9.70±0.10 mm) and S. aureus from gram-positive bacteria with inhibition zone ranging as (9.30±0.10-6.80±0.10 mm). Additionally, the highest antifungal activity was obtained against C. albicans from yeast-molds with inhibition zone ranging as (10.10±0.10-6.10±0.10 mm).

Nilgün-Doğan, Üyesi; Adanacıoğlu, Hakan
The main objective of this study was to assess the relationship between the level of consumers perception of products with geographical indication (GI) and their consumption of products with GI labels. Geographically indicated products were examined within the scope of Gumushane fruit pulp (mulberry pestil), which was registered as a Protected Geographical Indication (PGI) in 2004. This research conducted an online survey of 166 consumers living in Gumushane province in Turkey. Data was obtained from the online surveys that were conducted between June and September 2020. Binary logistic regression analysis method was used to identify the factors affecting the probability of consuming products with GI labels. The model results show that middle-aged, married, and middle-income and consumers who correctly perceive the concept of geographical indication products are more likely to consume products with GI labels. According to the logistic regression results, the increase in consumers level of correct perception of the product notion with GI label increases the probability of consuming products with GI label 2.5 times. The results of this study also tell us that the market share of these products can be increased by improving the consumer perception towards geographically indicated products. Policymakers can also take advantage of these insights to improve lucid understanding of how labels are actually interpreted by consumers.

Coruh, Emine; Urak, Faruk; Bilgic, Abdulbaki; Yen, Steven T.
Factors at the family scale, for which dynamic decisions and proper investments need to be made at the national level in curbing greenhouse gas emissions, are extremely important for policymakers and investors. We provide information on the roles of how household demographic factors shape transportation patterns and spending in Turkey using the latest survey data collected by the Turkish Statistical Institute (TSI). Alternative sample selection models are estimated to accommodate censoring in expenditure, and the dependent single-hurdle model is found to be the preferred model as a result of model specification tests. Also, different specification tests conducted, including the error-independence test, resulted in rejection of the null hypothesis. Results suggest that the majority of the household economic and sociodemographic characteristics are important determinants of both the probability and level of transportation expenditure. Policy recommendations to curb carbon emissions and integrate environmentally friendly transport systems throughout the country are presented.

Apaydin Cirik, Vildan; Gül, Uğur; Aksoy, Bahar
Aim: This study had three objectives: (1) determining the image of nursing in the eyes of undergraduate health sciences students; (2) identifying factors affecting that image; and (3) evaluating students’ views and experiences regarding that image. Background: If healthcare students perceive nursing positively, it may result in directing future generations to nursing, and improving nursing, and reducing the need for nurses. Design: This study adopted an explanatory sequential design with participant selection variant. The design involved data collection in two consecutive phases. Methods: A mixed-method design using quantitative data and qualitative interviews was used. In the quantitative phase, a descriptive and cross-sectional research method was used. The qualitative phase was based on phenomenological research. The quantitative portion was performed with 1556 participants in their second, third or fourth year during the 2019–2020 academic year. Students were from the nursing, emergency and disaster management, nutrition and dietetics, occupational health and safety, health management, and social work departments. The qualitative portion was performed with 29 participant volunteers. Participants were interviewed on the phone. The data were collected using an introductory information form, a nursing image scale, and semi-structured interviews. The quantitative data were analyzed using descriptive statistics and the independent-samples t-test, Mann-Whitney U test, one-way ANOVA, and stepwise linear regression. The quantitative data were analyzed using thematic analysis. Results: There were significant relationships between participants' nursing image scale total scores and their department (p < 0.001), education year (p = 0.014), age (p = 0.032) and desire to recommend the nursing profession (p < 0.001). Nursing image scale total score was significantly higher in nursing departments than in other departments. Second-year participants and 18–20-year-olds had higher total scores than fourth-year participants and 21–23-year-olds, respectively, and those who would recommend the nursing profession had higher total scores than those who would not recommend it (p < 0.05). Analysis of the qualitative data produced six main themes: perceptions of the nursing profession, perceived nursing figure, nurse knowledge, relationship with healthcare professionals, reason for preference and job gender. Conclusion: This study employed a mixed-method design involving both quantitative and qualitative stages. The results highlighted the image of nursing and its significance in the eyes of prospective healthcare professionals. Detecting nursing image early can increase professional training and improve the professional image of nursing. We should take into account the factors that negatively affect the image of nursing to plan nursing education better in the future.
