Impact of knowledge-sharing culture on organizational creativity: integrating explicit and tacit knowledge sharing as mediators
No full textPurposeTacit and explicit knowledge sharing play crucial roles in today's rapidly changing business environment, particularly in fostering innovation. However, uncovering tacit knowledge sharing remains complex. The purpose of this study is to analyze the mediating roles of tacit and explicit knowledge in the relationship between a knowledge-sharing culture and organizational creativity.Design/methodology/approachIn this study, the authors developed an extended analytical process to analyze the impact of explicit and tacit knowledge on a knowledge-sharing culture and organizational creativity. This process combines two analytical techniques: necessary condition analysis (NCA) and partial least squares structural equation modeling (PLS-SEM). NCA identifies essential bottlenecks for a specific outcome, while PLS-SEM uncovers strong connections between predictor and outcome variables. The authors applied these analyses to a sample of 155 IT experts from a leading telecom company in the Turkish ICT industry to test the relevant hypotheses.FindingsThe findings of this study indicate that tacit knowledge, rather than explicit knowledge, partially mediates the relationship between a knowledge-sharing culture and organizational creativity. This mediating role of tacit knowledge is particularly pronounced in the ICT sector. Additionally, the impact of organizational capabilities on organizational creativity is amplified by higher levels of tacit knowledge sharing.Originality/valueThe effect of organizational capabilities on organizational creativity was found to increase because of tacit knowledge sharing compared to explicit knowledge sharing, depending on the knowledge-sharing climate
The Effect of Online Consumer Reviews on Purchase Intention
No full textGünümüzde pazarlama ve reklam faaliyetleri sayıca artsa da nitelik açısından tartışılır konuma gelmektedir ve bu süreçte tüketiciler samimi görebileceği fikirlere daha çok ihtiyaç duymaktadır. Bu bağlamda bireyler kimi zaman internet ortamında tanımadıkları kişiler tarafından yazılan ürün yorumlarına başvurabilmektedir. Sürecin elektronik ortamda gerçekleşmesi ise elektronik ağızdan ağıza iletişimin satın alımlardaki etkisini gündeme getirmektedir. Gerçekleştirilen bu araştırmada elektronik ağızdan ağıza iletişimin satın alma niyetine yönelik etkisi incelenmiştir. İlave olarak, demografik değişkenlerin de düzenleyici rolü incelenmiştir. Tekirdağ ilinde gerçekleştirilmiş olan çalışmanın örneklem grubunda, kolayda örnekleme yöntemiyle 384 katılımcı yer almıştır. Veriler ise anket tekniğiyle toplanmış olup, bilgisayar ortamında kaydedilmiştir. Yapılan analizler neticesinde, elektronik ağızdan ağıza iletişimin nicelik ve nitelik boyutlarının satın alma niyetini etkilediği görülmüştür. Güvenilirlik boyutunun ise modeli açıklamada bir öneme sahip olmadığı sonucuna ulaşılmıştır. Çalışma kapsamında ayrıca, niceliğin satın alma niyetine olan etkisinde, alışveriş için ağırlıklı olarak tercih edilen mecranın yanı sıra, internetten aylık alışveriş sıklığı ve de yaş aralığının düzenleyici rol gösterdiği neticesine ulaşılmıştır.Today, although marketing and advertising activities are increasing in quantity, they are becoming questionable in terms of quality, and in this process, consumers are more in need of ideas that they can see sincerely. In this context, individuals can consult product reviews written by people they do not know on the internet. The fact that the process takes place in electronically brings up the effect of electronic word of mouth on purchases. In this study, the effect of electronic word of mouth on purchase intention was examined. The study also examined the moderating role of demographic variables. The sample group of the study conducted in Tekirdağ province included 384 participants by convenience sampling method. The data collected with the survey technique were recorded in computer. The result of the analysis, it was seen that quantity and quality factors of electronic word of mouth effect purchase intention. It has been concluded that the credibility factor does not have an importance in explaining the model. It has been concluded that in addition to the mainly preferred platform for shopping, monthly frequency of online shopping and age range played a moderator role in the effect of the quantity factor on purchase intention
Estimation of body measurements of sheep by Digital Image Processing
Get PDFFor the determination of body measurements in sheep the classical measurement method is generally used. However, measurements taken using classical methods are generally difficult, time-consuming, and often yield questionable results. In this study, the possibilities of using Image Processing Methods for measuring the body dimensions of Turkgeldi sheep were investigated. For this purpose, the body measurements of Turkgeldi sheep were determined using Image Processing Technology. In the study, measurements of 11 four-year-old Turkgeldi sheep raised at Namik Kemal University Research and Application Farm were obtained using both the traditional measurement method and image processing methods, and then the two methods were compared. To obtain measurements using the Image Processing Method, a scale with a diameter of 12 centimeters, divided into different colors for each centimeter, was placed on the animals as a reference point. The correlation coefficients between the methods for body measurements were calculated as 0.92 (P<0.01) for withers height (WH), 0.84 (P<0.01) for back height (BH), 0.82 (P<0.01) for rump height (RH), 0.83 (P<0.01) for back rump height (BRH), 0.61 (P<0.05) for chest deep (CD), 0.93 (P<0.01) for trunk length (TL), and 0.94 (P<0.01) for overall body length (BL)
MHD slip flow of ethylene glycol and water mixture based Al2O3 nanofluids between micro-parallel plates
No full textThe rapid growth of MEMS (micro-electromechanical systems) has led to increasing importance of determining the momentum and heat transfer properties of fluids in micro-scale MHD flow. The aim of this study is to determine how to remove the heat generated during the operation of MEMS from the system and how to affect the heat transfer by dispersing ethylene glycol-water mixture based Al2O3 nanoparticles at different particle volume concentrations in the presence of a magnetic field to minimize the heating in these devices. Calculations were made for 0 %, 4 % and 8 % nanoparticle volume ratios, 0, 0.02, 0.04 liquid layer thickness-nanoparticle radius ratios, 1 and 2 Hartman number values and 0:100, 50:50 and 100:0 ethylene glycol (EG)/water volume ratios. When the results are examined, the highest average Nu number values are achieved in 100:0 % EG/W used as the base fluid. Within the investigated ranges, 100:0 % EG/W provides maximum heat transfer rate improvement of approximately 0.54 % and 1.41 % over 0:100 % EG/W, respectively. Therefore, it was found that 100:0 % EG/W based Al2O3 nanofluid can be used as a suitable alternative method to remove the heat generated by MEMS (micro-electromechanical systems) during operation and minimize the heating in these devices
Comparison of the Principle of Separation of Powers in the Constitutions of Türkiye and Azerbaijan
Get PDFBu çalışmanın amacı Türkiye ve Azerbaycan’ın güçler ayrılığı ilkesinin görünümünün ve yasama, yürütme, yargıya ilişkin düzenlemelerinin karşılaştırılmalı olarak incelenmesidir. Bu amaç çerçevesinde Türkiye Cumhuriyeti Anayasası ve Azerbaycan Cumhuriyeti Anayasası doküman incelemesi yöntemi ile incelenmiş ve nitel araştırmalarda sıklıkla kullanılan içerik analizi yöntemiyle analiz edilmiştir. Makalede elde edilen bulgular Türkiye ve Azerbaycan anayasalarının yasama, yürütme ve yargıya ilişkin düzenlemeleri arasında oldukça büyük benzerlikler olduğunu ortaya koymuştur. Her iki ülkede de yasama yetkisi halk tarafından seçilen meclislere, yürütme yetkisi Cumhurbaşkanına, yargı yetkisi ise bağımsız mahkemelere verilmiştir. Aralarında küçük farklılıklar olsa da her iki ülkede de yasamayı oluşturan milletvekilleri ve yürütmenin başı olan Cumhurbaşkanında aranan nitelikler açıkça belirtilmiş, yaşa dayalı tecrübe, eğitim seviyesi ve ülke vatandaşı olma kriterlerine önem verilmiştir. Hem Türkiye hem de Azerbaycan anayasasında Cumhurbaşkanına yardımcı bir üst kurul niteliğinde olan Bakanlar Kurulu bulunmasına rağmen, özellikle başında bir başbakanın bulunması, düzenleme yapabilme yetkisinin verilmesi ve anayasada çeşitli görev ve yetkiler açıkça düzenlenmesi açısından Azerbaycan’da Bakanlar Kurulu’na daha özel bir statü verildiği görülmüştür. Anayasaların her ikisinde de yargı bölümlerinde mahkemeler ile hakim ve savcıların bağımsızlıkları anayasal güvence altına alınmış ve özellikle Anayasa Mahkemesi’ne ilişkin düzenlemelere geniş bir yer ayrılmıştır.This study aims to comparatively examine the appearance of the principle of separation of powers and the regulations regarding the legislature, executive, and judiciary in Türkiye and Azerbaijan. Within the framework of this purpose, the Constitution of the Republic of Türkiye and the Constitution of the Republic of Azerbaijan were examined by the document analysis method and analyzed by the content analysis method, which is a data analysis method frequently used in qualitative research. The findings obtained in the study revealed that there are great similarities between the legislative, executive, and judicial regulations of the Turkish and Azerbaijani constitutions. In both countries, legislative power is given to the Parliaments elected by the people, executive power is given to the President, and judicial power is given to independent courts. Although there are minor differences between them, in both countries, the qualifications required for the members of parliament who form the legislature and the President, who is the head of the executive, are clearly stated, and importance is given to the criteria of age-based experience, level of education and being a citizen of the country. Although there is a Council of Ministers in both the constitutions of Türkiye and Azerbaijan, which is a supreme council assisting the President, it has been observed that the Council of Ministers is given a more special status in Azerbaijan, especially in terms of having a prime minister at its head, being given the authority to make regulations, and clear regulating various duties and powers in the constitution. In both constitutions, the independence of the courts, judges, and prosecutors in the judicial departments is constitutionally guaranteed, and a wide space is allocated, especially for the regulations regarding the Constitutional Court
The Effect of Different Rootstocks and Berry Heterogeneity on Phytochemical Properties in Vitis vinifera Papazkarası Grape Variety
No full textProje değildirThere are differences in development and composition between the clusters on the vines and the grape berries on the clusters. Therefore, grouping berries by size in wine grape varieties can help better manage the composition of the wine to be produced. The aim of this research is to reveal the effect of berry heterogeneity on primary and secondary metabolites in the cv. Papazkarası. The Papazkarası vines are grafted onto the rootstocks 1103P, 110R, and 420A and are trained in the double Cordon Royat system. The clusters harvested from each rootstock were separated into individual berries. These berries were then grouped by size using sieves. The size groups were: ≤12.00mm; 12.01-14.00mm; 14.01-16.00mm; 16.01-18.00mm; and ≥18.00mm, forming five groups. A control group was created by taking berries from each size group. In terms of primary metabolites in the must, the Papazkarası/1103P combination and the ≥18.00 mm size group stood out. However, the maturity indices, °Brix, and % alcohol criteria were found to be insufficient for all rootstocks and berry sizes. Regarding secondary metabolites, it was found that the ≤12.00mm and 12.01-14.00mm size groups had high values in all graft combinations. The size group with the highest total anthocyanin and total phenolic content was the ≤12.00mm group. Based on these results, berry size reduction practices will improve quality. The quality of the wines obtained from different size groups should also be supported by sensory analyses. Sorting the berries by size will positively impact grape and thus wine quality
DIVAN-I MEZALİM'DEN OMBUDSMANLIĞA GEÇİŞ: KAMU DENETİMİ İHTİYACININ KARŞILANMASI
No full textThe concept of accountability is undoubtedly one of the most emphasized democratic issues in modern administrations. The concept of accountability has a very important place in Turkish administrative culture. The institution of Divan-ı Mezalim, of which we observe prominent examples in the Seljuk Empire, represents a primitive form of today's ombudsman from the trend of providing citizens with a platform to voice their complaints against government misconduct. This function developed in the Ottoman period with institutions such as the Divan-ı Hümayun, Şeyhülislam, and Kadı courts to ensure that the people's complaints were heard and addressed. In today's Turkey, the Ombudsman institution was established to act as a bridge between the state and citizens, reflecting an ancient tradition of public oversight and accountability. This study aims to show how the Divan-ı Mezalim, as a platform for seeking rights, may have opened the door to the Ombudsman in theory and practice. The study uses qualitative methods such as descriptive and historical analysis. The findings indicate that the institution of the Ombudsman has played a crucial role as a modern expression of accountability and public oversight mechanisms stretching back to the Ottoman era. Notably, the Ombudsman practice initiated in Sweden under Ottoman influence highlights how effective governance models can inspire other culturesHesap verebilirlik kavramı, kuşkusuz modern yönetimlerde üzerinde en çok durulan demokratik konulardan biridir. Hesap verebilirlik kavramı Türk yönetim kültüründe çok önemli bir yere sahiptir. Selçuklu İmparatorluğu'nda belirgin örneklerini gördüğümüz Divan-ı Mezalim kurumu, vatandaşlara devletin yanlış uygulalamalarına karşı şikâyetlerini dile getirebilecekleri bir platform sağlama fonksiyonundan hareketle günümüz ombudsmanlığının öncül bir biçimini temsil etmektedir. Bu fonksiyon Osmanlı döneminde Divan-ı Hümayun, Şeyhülislam ve Kadı mahkemeleri gibi kurumlarla halkın şikayetlerinin dinlenmesini ve ele alınmasını sağlamak üzere gelişmiştir. Günümüz Türkiye'sinde Ombudsmanlık kurumu, devlet ile vatandaşlar arasında bir köprü görevi görmek üzere kurulmuş olup, kamu gözetimi ve hesap verebilirliğine yönelik süregelen kadim bir geleneği yansıtmaktadır. Bu çalışma, bir hak arama platformu olarak Divan-ı Mezalim'in teoride ve pratikte Ombudsman'a nasıl kapı açmış olabileceğini göstermeyi amaçlamaktadır. Çalışmada nitel yöntemler olarak betimsel ve tarihsel analiz kullanılmıştır. Elde edilen bulgular göstermektedir ki Ombudsmanlık kurumu, Osmanlı’dan günümüze uzanan hesap verebilirlik ve kamuyu yönlendirme mekanizmalarının güncel bir ifadesi olarak önemli bir rol üstlenmiştir. Özellikle, Osmanlı etkisi altında İsveç’te başlayan Ombudsman uygulaması, etkin yönetişim modellerinin diğer kültürlere nasıl ilham verdiğini göstermektedir
Metropolitan managers' perspectives on Artificial Intelligence (AI) technologies
No full textThis qualitative study examines the perspectives of 60 public authorities from six metropolitan areas: Copenhagen, Helsinki, Bucharest, Milan, Prague, and Berlin, regarding the use of AI technologies in public service provision. The research explores both the potential benefits and challenges associated with AI implementation. Many respondents expressed positive attitudes towards AI as a tool to improve public service delivery, while others voiced concerns about AI's developmental stage. A portion of the participants indicated that their lack of familiarity and technological literacy regarding AI was a barrier to its effective adoption. This highlights the need for training programs to equip local authorities with the skills to utilize AI in enhancing public services. The study also analyzes the data using MAXQDA software to categorize themes and provide structured insights. The findings emphasize the importance of preparing metropolitan managers for AI integration and offer strategic proposals for its successful implementation in public administration. © 2025, IGI Global Scientific Publishing.

No full textIn this study, carbon material obtained from sunflower seed shells and doped with Fe and Zn using mint extract (Fe-Zn-SSSC) was prepared, and the usability of this adsorbent in the removal of paracetamol, diclofenac sodium, and tetracycline was investigated. Fe-Zn-SSSC was characterized by SEM-EDX and FTIR. Additionally, the effects of pH and adsorbent dosage on the removal of paracetamol, diclofenac sodium, and tetracycline were investigated. The removal rates of paracetamol, diclofenac sodium, and tetracycline were obtained as 88.7%, 65.4%, and 76.0% at a pH of 4, after 1 hour of adsorption with 5 g/L Fe-Zn-SSSC, respectively. The best removal of paracetamol, diclofenac sodium, and tetracycline was obtained at pH 4, with qmax values calculated as 14.51 mg/g, 6.33 mg/g, and 8.99 mg/g, respectively. It was determined that the adsorption of paracetamol, diclofenac sodium, and tetracycline with Fe-Zn-SSSC was more compatible with the Langmuir isotherm model and pseudo-second-order kinetic model. As a result, this study demonstrates that carbon materials synthesized from sunflower seed shells can serve as an effective and low-cost adsorbent for drug from water
In the context of the social state principle; The relationship of health services provided during the COVID-19 pandemic process with happiness
No full textSosyal devlet, kişileri toplumsal tehlikelere karşı koruma altına alarak asgari yaşam güvencesine sahip olmalarını sağlayan ve tüm vatandaşlara eğitim, sağlık ve barınma gibi temel hizmetleri eşit bir şekilde sunmayı hedefleyen bir sistemdir. Bu kavram, kapitalist sistemin ortaya çıkardığı refahın nasıl paylaşılacağı sorunu çerçevesinde teorik bir önem kazanmıştır. Uygulama sahasına geçişi ise, 20. yüzyılın ikinci yarısında savaşların ve ekonomik krizlerin ardından toplumda yardıma muhtaç kesimlerin artışıyla mümkün olmuştur. Sağlık hizmetleri, toplumun her bireyi tarafından ihtiyaç duyulduğunda erişilebilir ve yeterli kalitede olmalıdır. Bu hizmetlerin, bireylerin gelir düzeyine bakılmaksızın devlet tarafından sağlanması, sosyal devlet anlayışının temel bir ilkesidir. Türkiye bir sosyal hukuk devleti olarak, sosyal devlet ilkesi doğrultusunda sağlık hizmetlerini vatandaşlarına sunma görevini üstlenmiştir. Türkiye'de pandemi sürecinde Covid-19 aşıları olan Almanya'nın BioNTech Pfizer aşısı, Çin'in Sinovac aşısı, Rusya'nın Sputnik V aşısı ve 30 Aralık 2021 tarihinden itibaren kullanılan yerli aşı olan Turkuvac aşısı ve PCR testleri ücretsiz olarak kullanıma sunulmuştur. Yine bu süreçte temaslı takibini, salgını yönetimini ve evde hastaları izlemek üzere, Covid-19 belirtisi gösterenlerin, PCR testi pozitif çıkanların ve koronavirüs teşhisi konularak karantinada olan hastaların takibini yapmak üzere filyasyon ekipleri kurulmuştur. İçişleri Bakanlığı öncülüğünde Valiliklerin ve kaymakamlıkların koordinasyonunda kurulan Vefa Destek Gruplarıyla dezenfektan, kolonya, maske vb. gibi hijyen malzemelerinin yanı sıra gündelik ihtiyaçlar da karşılanmıştır. Aile, Çalışma ve Sosyal Hizmetler Bakanlığı tarafından başlatılan "Sosyal Destek Programı" kapsamında; Mali Destek Yardımı, Kısa Çalışma Ödeneği, Nakdi Ücret Desteği, İşsizlik Sigortası Fonu ve İşsizlik Ödeneğiyle yardım programları hayata geçirilmiştir. Türkiye'nin bu süreçte verdiği sağlık hizmetlerinin diğer ülkelere göre sosyal devlet ilkesi bağlamında mutluluk ile ilişkisini incelemektir.The social state is a system that aims to provide individuals with minimum life security by protecting them against social dangers and to provide basic services such as education, health and housing equally to all citizens. This concept has gained theoretical importance within the framework of the problem of how to share the welfare created by the capitalist system. Its transition to the field of application became possible with the increase in the needy segments of society after wars and economic crises in the second half of the 20th century. Health services should be accessible and of sufficient quality when needed by every individual in society. It is a fundamental principle of the social state concept that these services are provided by the state regardless of the income level of individuals. As a social state governed by the rule of law, Turkey has undertaken the duty of providing health services to its citizens in line with the principle of the social state. During the pandemic process in Turkey, the Covid-19 vaccines Germany's BioNTech Pfizer vaccine, China's Sinovac vaccine, Russia's Sputnik V vaccine and the Turkuvac vaccine, which has been used domestically since December 30, 2021, and PCR tests have been made available free of charge. Again, during this process, contact tracing, outbreak management and monitoring patients at home, contact tracing teams were established to monitor those showing Covid-19 symptoms, those with positive PCR tests and those who were diagnosed with coronavirus and were quarantined. In addition to hygiene materials such as disinfectant, cologne, masks, etc., daily needs were also met with Vefa Support Groups established under the leadership of the Ministry of Interior and the coordination of Governorships and District Governorships. Within the scope of the "Social Support Program" initiated by the Ministry of Family, Labor and Social Services; Financial Support Assistance, Short-Time Work Allowance, Cash Wage Support, Unemployment Insurance Fund and Unemployment Benefit aid programs were implemented. The aim of this study is to examine the relationship between the health services provided by Turkey in this process and happiness in the context of the social state principle compared to other countries
