A governance model for ıncreasing the positive effects of ınstitutions on the long run economic growth

The main aim of this study is to critically analyze the effects of institutions on economic growth on the basis of a deeply literature review with a technological point of view. This study found that culture, traditions, tacit knowledge, openness to innovations are the outstanding points in new century and we assert that for increasing positive effects of institutions in the long term there should be a model for management and governance of business of institutions that is the whole economy in the digital macroeconomics. In the era of the upcoming industry 4.0, smart cities and egovernment paradigms there should be integration of IT and business processes via a valid management and governance model. With the assumption that innovation digestion and cutting-edge IT capability of institutions have positive effect on their profitability and competency in the market, COBIT model is found to be a valid and sustainable framework for effective and efficient institutional set-ups that provide a sustainable platform for economic value creation cycle.Bu çalışmanın temel amacı, kurumların ekonomik büyüme üzerindeki etkilerini derinlemesine bir literatür taraması temelinde eleştirel olarak analiz etmek ve teknolojik bakış açısıyla bu hususta bir çözümleme üretmeye çalışmaktır. Bu çalışma, kültür, gelenekler, zımni bilginin, yeniliklere açıklığın, yeni yüzyılda öne çıkan noktalar olduğunu ve uzun vadede kurumların olumlu etkilerini arttırmak için kurumların dijital makroekonomide bir yönetim ve yönetişim modelinin gerektiğini ortaya koymuştur. Endustri 4.0, akıllı şehirler ve e-devlet çağında bilgi teknolojileri (BT) ile iş süreçlerinin bir geçerli yönetim ve yönetişim modeli sayesinde entegre edilmesi gerekir.

İslamiyet Öncesi Türk Devletlerinde öldürülen ve intihar eden hükümdarlar

Dünyada Türk tarihine baktığımızda Türklerin, bir coğrafyada sabit olarak yaşadığını görmek pek mümkün değildir. Pek çok coğrafyada boy göstermişlerdir. Bir milletin yerinde durmayıp da sürekli yer değiştirmesi olağan bir şey değildir. Milletler durduk yere ülkesinden, toprağından vazgeçip başka coğrafyalara göçmezler. Milletlerin farklı coğrafyalara göç etmesinin birçok nedeni olmuştur. Kimi devletler ekonomik nedenlerle, kimi devletler de siyasi nedenlerle göç etmişlerdir. Türklerin yaptıkları göçlerinin sebeplerine baktığımızda ilkim değişikliği, açlık ve kuraklık gibi tabii felaketlerin yanı sıra kendi aralarında ve komşu kavimlerle yaptıkları savaşların etkili olduğu görülmektedir. Toprağın artan nüfusu besleyemez hale gelmesi ve temel ekonomisi hayvancılığa dayalı bir toplumun sürüleri için gerekli olan yaylak arayışına girmeleri de göçlerin önemli sebepleri arasındadır.2 Öte yandan nüfusun artması sonucu yaşanan göç hareketlerinin yanı sıra Türk cihan hâkimiyet anlayışı gereğince gerçekleşen göçlere de rastlanır

A simple heart valve replacement technique which improves surgical time

Aim of the study: Different heart valve replacement techniques have been described in the literature. In the present study, a simple and very fast heart valve replacement technique is presented. Material and methods: In a two-year period, 87 patients with the diagnosis of mitral valve disease, aortic valve disease or combined valve disease underwent valve replacement performed by the same surgeon. In this technique, the valve was implanted with the valve clamped to the surgical dressing without the assistant holding it. Patients with coexisting surgical pathologies were excluded from the study. A control group was created among the patients who were operated on during the same time period by different surgeons with the assistant holding the prosthesis. Control group operations were done by conventional valve holding and suturing techniques. Results: Mean age of the patients was 61.6 ± 3.2 years. Mitral valve replacement (MVR) was done to 51 patients, aortic valve replacement (AVR) to 12 patients and both aortic and MVR to 24 patients. Aortic cross clamp duration was 30.7 ± 3.3 min for MVR, 34.8 ± 6.2 min for AVR and 69.1 ± 6.1 min for both valve replacements. Aortic clamping durations were significantly higher in the conventional implantation technique. Discussion: The described technique has many advantages such as short myocardial ischemia duration, better exposure of the surgical field and facilitation of assistance. © 2014 Termedia Sp. z o.o.

A Novel Blind Adaptive Beamformer with Robustness against Mutual Coupling and Miscalibration Effects

Beamforming techniques utilized either at the transmitter or the receiver terminals have achieved superior quality-of-service performances from both the multi-antenna wireless communications systems, communications intelligence and radar target detection perspectives. Despite the overwhelming advantages in ideal operating conditions, beamforming approaches have been shown to face substantial performance degradations due to unknown mutual coupling effects and miscalibrated array elements. As a promising solution, blind beamformers have been proposed as a class of receiver beamformers that do not require a reference signal to operate. In this paper, a novel gradient-based blind beamformer is introduced with the aim of mitigating the deteriorating effects of unknown mutual coupling or miscalibration effects. The proposed approach is shown to find the optimal weights in different antenna array configurations in the presence of several unknown imperfections (e.g., mutual coupling effects, miscalibration effects due to gain and phase variations, inaccurate antenna positions). By providing numerical results related to the proposed algorithm for different array configurations, and bench-marking with the other existing approaches, the proposed scheme has been shown to achieve superior performance in many aspects. Additionally, a measurement-based analysis has been included with validation purposes.Comment: Presented in EuCAP 2023, Copyright IEE
