Human capital is a major driver of regional growth and provides insight into degrees of regional disparity (Barro & Lee ). Addressing these disparities is crucial to economic stability and cohesion in Turkey; therefore, we investigated the regional distribution of human capital and its evolution between 2008 and 2012. We used district level address‐based population registration system data from 957 districts to analyze regional human capital disparities and report significant results. Specifically, regional disparities in human capital are decreasing in Turkey, but enormous regional district level disparities persist. A disparity exists between the western and eastern regions in human capital at both primary and secondary educational levels. However, this east–west dualism almost disappears with regard to human capital at the tertiary educational level, which is heavily concentrated in Turkey's major cities (Istanbul, Ankara, Izmir, Kocaeli, and Bursa).

Aim of the present article 1 is to investigate the impact of trade liberalization on the evolution of regional income inequalities in Turkey between 2004-2011. Despite the large body of literature on this subject, there exists several directions which needs to be further explored. i. so far in the literature, the concept of trade openness is too broadly defined. However, it is not only 'trade' per se that can affect the regional economies but the composition of trade is also of great importance (Rodriquez-Pose and Gill, 2006). Indeed, it can be partitioned into two components, such as exports and imports. We analyze separately the impact of each component on the evolution of regional inequalities. ii. in most of the empirical studies dealing with this issue, neighboring regions are assumed to have no spatial economic interconnection between each other. We, therefore, incorporate spatial spillovers of trade and growth into our analysis. Our results are summarized in two groups: First, regional inequalities in Turkey are quite sizable but tend to decline over the period of analyses. Second, initially poorer regions that experience an export-based liberalization tend to grow faster than richer ones. Imports, on the other hand, have an opposite effect.

Recent technological and philosophical research has revealed that almost everything around us is heavily dependent on network-based complexities. Airport network topologies are complex networks and their analyses are crucial regarding the fact that the evolution of airport network topology influences the economic growth of regions and countries. An equal population cartogram is derived displaying the distortion of the air transport network of Turkey in accordance with the uneven distribution of passengers. The regions between İstanbul, Ankara, İzmir, and Antalya are shrunk by the force of higher population concentration. The shrinkage across the eastern regions is less than that in the western regions; still, the distortion of the regions is dominated by particular regional hubs.

Objective Local treatments used in metastatic liver tumours efficiently control the disease and survival. Transarterial radioembolisation (TARE) is a safely used locoregional treatment method. We aim to investigate the impact of TARE on different kinds of metastatic liver tumours and the effect of pre-treatment clinical findings. Material and Methods The patients with metastatic liver tumours referred to our department for radioembolisation were retrospectively evaluated. All patients were given a Y-90 glass microsphere after being selected by the appropriate clinical and imaging criteria, lung shunt fraction levels, vascular investigation, and macro aggregated albumin (MAA) scintigraphy performed in the angiography unit. Results Thirty-four (17 women, 17 men) patients were suitable for the treatment. Patients were treated with 115.88±47.84 Gy Y-90 glass Microspheres. The mean survival rate was 14.59±12.59 months after treatment. Higher survival rates were detected in patients who had higher pre-treatment serum albumin levels. The optimum cut-off value of albumin to predict response to treatment was 4 g/dl with 88.89% sensitivity, 62.50% specificity, 72.73% PPV and 83.33% NPV. Furthermore, one unit increase in age increased mortality 1.152 times in our patient group. Conclusion Radioembolisation is a safe and efficient method for controlling metastatic liver disease. Albumin levels significantly affect predicting response; higher albumin levels are related to higher survival rates. Furthermore, older age positively correlated with mortality rates in our patient group.

Havacılık sektörü yüksek ve kaliteli sosyal sermaye ve yüksek teknoloji içeren sermaye yoğun bir sektördür. Bu nedenle hem ülke ekonomileri hem de bölge ekonomileri için stratejik önem arz etmektedir. Hava taşımacılığı ağları dolaşımını sağladıkları yolcu, yük ve bilginin yanı sıra havacılık sektörünün tamamlayıcısı sektörlerin bölgelerde yerleşmesiyle yerli ve yabancı yatırımları da bölgelere çekebilmektedirler. Türk Hava Ulaşım Ağı (THUA), 1930'da başlayan neredeyse bir asırlık bir geçmişe sahiptir ve bugün dünyanın en büyük havalimanı ve küresel bir bayrak taşıyıcısı ile büyümeye devam etmektedir. Bu bağlamda, bu makale THUA’nın 2012-2017 periyodunda her yıl için mekânsal-karmaşık ağ analizlerini kullanarak değişimini modellemekte, makine öğrenmesi modelleri kullanarak THUA’da havalimanları arasında yeni bir bağın oluşum olasılığına sosyo-ekonomik ve ağ ölçütü tabanlı dinamiklerin etkilerini tahmin etmekte ve önemli sonuçlar ortaya koymaktadır. THUA her ne kadar seyrek bir ağsa da yoğunlaşma eğilimindedir. Yeni bağlar düğümler arasında rastlantısal olarak oluşmamakta aksine belirli havalimanları arasında oluşmaktadır. Gelir ve nüfus ve ayrıca derece merkeziliği ve kümelenme katsayısı havalimanı çiftleri arasında yeni bir bağın oluşma olasılığını arttırmaktadır.
