Kadiogullari, Ali Ihsan; Keles, Sedat; Baskent, Emin Zeki; Bingöl, Ozkan
Spatial Decision Support System is indispensable to develop spatial planning alternative by integrating spatial parameters into forest management plans using ecosystem based multiple use forest management planning concept (EBMUFM). Spatial forest planning provides several opportunities to decision makers to generate spatially implementable harvest schedules and perform spatial analyses as part of integrated planning. This paper presents the role and importance of spatial forest planning in forest management, and evaluates it in the context of Turkish forestry. Basic concepts related to spatial forest planning are explained. Some important intuitive decision support techniques (modeling techniques) widely used in spatial forest management planning were introduced. Further, spatial decision support systems for forest management planning developed in various countries were provided. Finally, it is concluded that spatial forest planning is extremely needed in EBMUFM.

Aktas, Haktan; Ürkek, Bayram; Aktas, Hacer Meral; Çetin, Bulent; Sengül, Mustafa
In the study, some physicochemical, viscosity, rheological properties, benzoic and sorbic acid contents of a total of 96 yoghurt samples (consisting of homemade, local and national) collected from different provinces of Turkey were investigated. It was determined that national yoghurt samples had the highest average dry matter (13.8%) and the lowest syneresis values (35.8%). Homemade yoghurts had the lowest average viscosity (at 20 rpm, 4079 cP; 50 rpm, 2142 cP), consistency coefficient values (44.4). It was determined that the flow behavior index values of all yoghurt samples were between 0 and 1 and showed pseudoplastic behavior. It was found that the national commercial yoghurt samples were higher than the homemade and regional samples in terms of dry matter, syneresis, viscosity and consistency coefficient. Although the mean benzoic acid values were detected between 5.43 and 31.9 mg kg(-1), sorbic acid was found in only one sample (local brand yoghurt sample).

Bucurgat, Mahmut; Özdemir, Ahmet Faruk; Altindal, Semsettin
Different thicknesses of Si3N4 insulator layers were grown on an (Au: Ti)/n-GaAs (MS) reference structure to analyze the effect of these layers with/without illumination on the electrical characteristics and compare the results between these structures. With this motivation, current measurements were made as a function of voltage over +/- 3 V, either in the dark or at 20-100 mW cm- 2 illumination with an increment of 20 mW cm- 2. Some important electric and optoelectronic parameters, such as barrier height at zero bias, ideality factor, saturation current at reverse bias, photosensitivity, photoresponsivity, and detectivity, have been determined using currentvoltage data in relation to illumination intensity. To compare the calculation methods used, the basic electrical parameters, the barrier height at zero bias, the ideality factor, and the series resistance were calculated first using the Thermionic Emission Method and then, alternatively, using Cheung functions. Additionally, the dependence of energy of the interface states was investigated using forward bias current voltage data with the ideality factor and barrier height with/without different intensities of illumination, because of their reordering/restructuring in electric field effects and illumination. The voltage-dependent characteristics of resistance of these structures were also determined from Ohm's Law for each illumination intensity.

Kaygusuz, K; Kaygusuz, A
Turkey is an energy importing country; more than half of the energy requirement has been supplied by imports. Domestic oil and lignite reserves are limited, and lignites are characterized by high ash, sulfur and moisture content. In this regard, renewable energy resources appear to be one of the most efficient and effective solutions for sustainable energy development in Turkey. Turkey's geographical location has several advantages for extensive use of most of these renewable energy sources. Because of this and the fact that it has limited fossil fuel resources, a gradual shift from fossil fuels to renewables seems to be serious and the sole alternative for Turkey. This article presents a review of the present energy situation and sustainability, technical and economical potential of renewable energy sources, and future policies for the energy, sector in Turkey. Throughout this paper several problems relating to energy sources and sustainable development are discussed from both current and future perspectives.

Objective: Metabolic syndrome (MetS) is a complex disease characterized by insulin resistance, abdominal obesity, hyperglycemia, hypertension, hypertriglyceridemia and low HDL-cholesterol level. The aim of the study was to evaluate the sequence variations in the LPIN1 gene in MetS. This gene codes lipin-1 protein which functions as Mg-dependent phosphatidic phosphatase enzyme and transcriptional coactivator. Material and Methods: The study groups included 73 MetS (19 M/54 F) and 56 non-MetS (16 M/40 F). Sequence variation in exons 2, 4, 5 and 14 of the LPIN1 gene were investigated by DNA sequencing method. Results: c.696 G>C variant (p.S232S) in exon 5 was observed in only one women with MetS. But this variation is not important because of coding same amino acid. Conclusion: Any important sequence variant was not detected in exons 2, 4, 5 and 14 in the LPIN1 gene in MetS.

To evaluate the predictive value of immature granulocytes in intestinal necrosis in incarcerated hernia. The study included patients who were operated on due to incarcerated hernia. The cases were separated into 2 groups as those with or without bowel resection. Age, gender, hernia type, side, white blood cell count, neutrophil count, neutrophil-lymphocyte ratio, red cell distribution width count, immature granulocyte count, platelet count, and platelet lymphocyte ratio were statistically compared between the groups. There were 27 cases (17.3%) in the group with bowel resection and 127 cases (82.7%) in the group without bowel resection. A statistically significant difference was determined between the groups in respect of the hernia type, white blood cell count, neutrophil count, neutrophil-lymphocyte ratio and immature granulocyte count (p<0.05). The cut-off value of the immature granulocyte count was found to be 0.065, with sensitivity of 63% and specificity of 80%. In multivariate analysis, age over 65 years and immature granulocyte count>0.065 were found to be independent predictors of necrosis development. The immature granulocyte value is a fast, easily accessible and reliable marker that can be used to predict intestinal necrosis in cases of incarcerated hernia.

- MakaleYalnız künye2026Scopus SJRQ2How 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.

Küçükosman, Asiye; Uzun, Sumeyye
This study examines the causality relationship between portfolio investments and credit default swaps (CDS) in T & uuml;rkiye. Analysing the dynamics between portfolio investments and CDS premiums, two important variables for financial markets is critical to understanding how risk perception and investment decisions are affected. While portfolio investments are generally considered an indicator of the confidence of foreign investors in the country's economy, CDS premiums are an important risk measure that reflects the country's debt risk and the risk perception of market participants. In this context, examining the relationships between the two variables contributes to the understanding of the effects of investor behavior and risk perception on macroeconomic indicators in financial markets. In the study, the Granger causality test was applied using data from the period 2014Q1-2024Q1. The results obtained show that CDS premiums have a significant and unidirectional causal effect on portfolio investments. Increases in CDS premiums increase investors' risk perception and lead to a decrease in portfolio investments. On the other hand, no causal effect of portfolio investments on CDS premiums was found. These findings emphasize the importance of risk management in terms of portfolio investments in T & uuml;rkiye and reveal that CDS premiums play a role in investor decisions.
