Ninety years of k-tridiagonal matrices
Authors: da Fonseca Carlos M. , Kowalenko Victor , Losonczi László 
Published: October 2020

AbstractThis survey revisits Jenő Egerváry and Otto Szász’s article of 1928 on trigonometric polynomials and simple structured matrices focussing mainly on the latter topic. In particular, we concentrate on the spectral theory for the first type of the matrices introduced in the article, which are today referred to as k-tridiagonal matrices, and then discuss the explosion of interest in them over the last two decades, most of which could have benefitted from the seminal article, had it not been overlooked.
Lemniscate and exponential starlikeness of regular Coulomb wave functions
Authors: Aktaş İbrahim 
Published: October 2020

AbstractIn this study, a normalized form of regular Coulomb wave function is considered. By using the differential subordinations method due to Miller and Mocanu, we determine some conditions on the parameters such that the normalized regular Coulomb wave function is lemniscate starlike and exponential starlike in the open unit disk, respectively. In additon, by using the relationship between the regular Coulomb wave function and the Bessel function of the first kind we give some conditions for which the classical Bessel function of the first kind is lemniscate and exponential starlike in the unit disk 𝔻.
Quadrilateral cell graphs of the normalizer with signature (2,4,∞)
Authors: Gözütok Nazli Yazici , Güler Bahadir Özgür 
Published: October 2020

AbstractIn this study, we investigate suborbital graphs Gu,n of the normalizer ΓB (N) of Γ0 (N) in PSL(2, ℝ) for N = 2α3β where α = 1, 3, 5, 7, and β = 0 or 2. In these cases the normalizer becomes a triangle group and graphs arising from the action of the normalizer contain quadrilateral circuits. In order to obtain graphs, we first define an imprimitive action of ΓB (N) on using the group (N) and then obtain some properties of the graphs arising from this action.
China – Cooperation and rivalry in today's interdependent world: Will pandemic change the trends?
Authors: Hübner Wojciech 
Published: October 2020

AbstractThe paper examines the importance of the ‘Chinese factor’ in today's world from the perspective of current phenomena such as particular political and economic uncertainty and also examines them against the background of processes of global cooperation and parallel unprecedented competition at the same level. Complex phenomena occurring in this area have recently been additionally disrupted by the outbreak of the COVID-19 pandemic. Will the world be different?Globalization processes have taken place over the centuries but have gained particular importance in our present times, because we left ‘the golden age’ of globalization (1990–2010) already behind us. China, ever louder, talks about the need for a ‘new’ globalization, in line with its new aspirations as a pretender to the leadership position in the global economy. The Belt and Road Initiative, launched in 2013, has been in the centre of its vision. It has become the foundation for China's foreign policy in the horizon of at least the middle of XXI century. It was designed to re-confirm China's unprecedented economic success of the past four decades, which to a great extent could be derived from a skilful use of the ‘traditional’ mechanisms of globalization.
The great Chinese transformation: From the third to the first world
Authors: Kolodko Grzegorz W. 
Published: October 2020

AbstractIn the era of irreversible globalisation, the worldwide economic and political rules of play must take into account of the growing importance of China. Rather than fight the country, one should pragmatically cooperate on solving the mounting global problems. Contemporarily, both China should adapt to the external world and the world itself should adapt to China. There is no possibility of imposing on it a model developed elsewhere, especially that these days liberal democracy is experiencing a systemic crisis in many countries. Neither is there a chance to impose the Chinese model on others, though it seems tempting to a country; it is not an exportable ‘commodity,’ but its elements may prove useful elsewhere. China is not aiming for global domination; instead, it is consistently integrating with the world to maintain its own development. The only reasonable way forward is thorough observation, mutual learning and pragmatic collaboration based on the non-orthodox economic thought.

AbstractThe objective of this research is to develop the equipment for liquid-jet forming of women's headwear hats, which will allow expanding design assortment of these products. The equipment for cyclic liquid-jet forming of headwear hats in liquid-active working environment (LAWE) with forming element rotation was designed. The mechanism of movement and orientation of liquid -jet forming nozzle was developed, which allows influencing fabric parts by flooded and controlled liquid-jet, repeating the contour at a certain distance and with appropriate angle attack on each technological section of the part. The conducted experimental research allowed to receive semi-spherical forms of headwear hats from six fabrics suit-coat assortments, which are one of the most difficult forms of non-seam forming. Completely formed hats of a given complex configuration were obtained by liquid-jet forming, different from standard semi-spherical ones. The developed equipment provides mobility of the production from the point of view of quick equipment adaptation due to action use of flooded controlled liquid-jet and forming of a significant number of various hats contours, various combinations of technological forming modes.

Published: October 2020

AbstractKosovo is one of the poorest countries in Europe, despite the various poverty alleviation programs implemented by the authorities and the international funding community. This study aims to analyze income distribution inequality and factors behind rural households' poverty in Kosovo. Data on farm income, nonfarm income, unearned income, and socio-economic characteristics were collected using a semi-structured questionnaire from 203 randomly selected households in Kosovo. Linear regression, one-way ANOVA, and different versions of poverty indexes were used to examine the data. One-quarter of households' income comes from nonfarm activities. The middle-income households had the highest potential to find alternative employment in the nonfarm sector. Years of education, household size, number of family members above the age of 18, and total income had a positive impact on nonfarm revenues. The poorest rural households had the highest share of income from farm activities (77.52%). Nonfarm revenues have a positive impact on poverty alleviation; thus, the study suggests adopting suitable rural policies to enhance nonfarm employment for vulnerable rural households. The agro-tourism sector and circular economy approaches in agriculture with the focus on renewable energy can be considered as potential sources of nonfarm income, which could lead to sustainable poverty reduction.
Summer of 1735 in Cyprus: Vassiliy Grigorovich-Barskiy travelling during epidemic
Authors: Buzykina Yu. N. 
Published: October 2020

The object of the research is the description of the monasteries of Cyprus, made by Vassiliy Grigorovich-Barskiy in 1735-1736. The outbreak that happened after the earthquake on April 10, 1735 had a significant impact on the choice of the route by the traveler: he went to inspect the remote monasteries of the island. The purpose of the study is to identify the true goals of his expedition, to make an assumption about his patron, to point sources of information that Barskiy used. The tasks of the study are to demonstrate how Barskiy used the epidemic in Cyprus to compile description of the local monasteries. I will try to answer the questions, why is he wandering the island during the epidemic, why is he describing monasteries, ignoring many other objects, and finally where did Barskiy, who had previously visited only the most famous places in Cyprus, take such an accurate information about the number of monasteries and their location, because it is impossible to see and describe so much going at random.

Published: October 2020

Dünya nüfusunun artmasıyla arazi üzerindeki baskı artmaktadır. Doğal bir süreç olan erozyon bu artan baskı ile problem haline gelmiştir. Türkiye’de birçok arazi özellikle tarım arazileri erozyon etkisi altında bulunmaktadır. Bu nedenle erozyon etkisini azaltmak için birçok yöntem ve yaklaşımlar geliştirilmiş ve geliştirilmeye devam etmektedir. Bu çalışma ile Bulanık Mantık Analitik Hiyerarşik Süreç (BAHS) yaklaşımı kullanılarak, 586200 ha alan kaplayan Sinop ili arazilerinin erozyon duyarlılık sınıflarının belirlemesi ve haritalanması amaçlanmıştır. Sinop ili Karadeniz Bölgesi’nde yer almaktadır. İlin kuzeyinde Karadeniz, güneydoğusunda Samsun, güneyinde Çorum, batısında Kastamonu illeri bulunmaktadır. Çalışmada erozyon risk sınıfları belirlenirken hem toplam veri seti (TVS) hem de minimum veri seti (MVS) oluşturulmuş ve sonuçları karşılaştırılmıştır. Erozyon sınıfları oluştururken TVS için jeoloji, bitki örtüsü, arazi kullanımı, eğim, derinlik, yağış ve erodobilite parametreleri kullanılmıştır. MVS oluşturulmasında ise temel bileşenler analizi sonucunda, bitki örtüsü, derinlik ve erodobilite parametreleri ele alınmıştır. TVS ve MVS için yapılan sonuç haritasında doğrusal kombinasyon yöntemi uygulanmış ve bu yöntem uygulanırken ArcGIS coğrafi bilgi sistemi programından yararlanılmıştır. Elde edilen sonuçlara göre, TVS’de çalışma alanının % 33’ü yüksek ve çok yüksek, %36’sı ise düşük düzeyde erozyona duyarlı olduğu belirlenirken, MVS’ye göre ise çalışma alanının % 33’ü yüksek ve çok yüksek ve % 35’i düşük erozyona duyarlı olduğu belirlenmiştir. Böylece TVS ve MVS ile elde edilen sonuçların oldukça birbirine yakın değerler gösterdiği tespit edilmiştir. TVS ve MVS ile yapılmış her iki erozyon duyarlılık haritası da, özellikle bitki örtüsünün zayıf ve eğimin yüksek olduğu alanlar ile işlemeli tarımın yapıldığı araziler erozyona çok yüksek duyarlı oldukları görülmektedir.
Knowledge, attitude and practice of health care providers toward prescribing factor replacement at federally funded haemophilia treatment centres in the United States
Authors: Bloomberg M. , Sargenton K. , Gattamorta K. , Anglade D. 
Published: October 2020

Abstract
Factor replacement is currently the standard of care to prevent or treat bleeding episodes in haemophilia patients. This study examined current prescribing practices of factor therapy for patients at haemophilia treatment centres (HTCs) in the United States.

Aims
The aims were to evaluate the driving forces for prescribing factor products, to evaluate current attitudes and knowledge toward factor product and industry, and to discuss the implications for health care providers in practice.

Methods
An anonymous electronic survey was distributed to 744 HTC health care providers (HCPs); 118 responses were analysed.

Results
The most common driving force for HCPs to change a patient's factor product was poor response to current therapy, while the most common perception of patients’ motivation to switch products was the potential for fewer infusions. HCPs with strong influence over the prescribed therapy identified inadequate pharmacokinetic (PK) studies as an important driving force; patients/caregivers perceived as having a strong influence over which therapy is prescribed selected less frequent dosing as an important motivator. HCPs who allow patients/caregivers to have a strong influence over which factor is prescribed were more likely to cite patient/caregiver request as a significant driving force for change in therapy.

Conclusion
The haemophilia treatment landscape continues to evolve and is becoming increasingly complex. The multitude of treatment options available now offer choices, presenting a need to focus on patient-centric prophylaxis.

The Value of Pedagogical Preferences: A Case of Personality and Learning Environments in Higher Education
Authors: Davies Jean L , Wilson Thomas L 
Published: October 2020

To improve learning outcomes, research evidence has accumulated regarding the principles of teaching and learning; however, students’ perceptions of teaching methods have received little scientific investigation toward enhanced quality of their learning. To provide a demonstration of the value of researching student perceptions of the learning environments in which they find themselves, a sample of preference ratings (n = 69) was examined to test the hypothesis there exist among the Five Factor personality dimensions correlates of preference ratings for three environments: teacher-led, independent-autonomous, and groups. Results confirmed preference for group learning in our sample and statistically reliable zero-order positive correlations between group-based learning preference and both extraversion and openness scores and between preference for teacher-led environments and openness scores. First-order correlations showed no significant changes in accounted preference variation when controlling the other personality factors scores. These findings are discussed with respect to likely social-cognitive and neurodevelopmental bases of group learning effectiveness and the utility of investigating student preferences for improving the quality of learning.
‘Taking a calculated risk’- Is American College of Surgeon’s National Surgical Quality Improvement Program universal risk calculator a valuable tool to improve quality of surgical services in Indian surgical scenario?
Authors: Dave Prakash , Kamisetty Krishna P. 
Published: October 2020

Background: American College of Surgeon’s National Surgical Quality Improvement Program (ACS NSQIP) risk calculator is a valuable tool exercised in the hospitals across the USA for predicting risk rates for 8 post-operative complications till the 30th post-operative day, taking into account 21 risk factors. Its applicability in the surgical practice in India has not been popular. This study explores, if this model is accurate in predicting risk of post-operative complications in surgical patients in India. Methods: Retrospective study done on 368 patients who underwent elective and emergency surgical procedures in a medical college hospital. Demographic data, contemplated surgery, co-morbid factors entered into the risk calculator and predicted personal risk calculated and compared to average risk. Post-operative progress reports retrieved. Complications till 30th post op day compared with the predicted risk estimates. Brier score, sensitivity and specificity, PPV/NPV, z and p values calculated for the probabilistic, predictive values of the model for validation.Results: Emergency procedures done in 143 and elective in 225. 67 developed major, 35 minor, 11 fatal complications. The average Brier score was 0.00324. Mean sensitivity was 96.08 %, specificity 98.94%. Mean PPV 82.6%, NPV 99.6%. The predictions were inaccurate for serious, “any” complications, discharge to nursing and rehabilitative facility, the colectomy ileus and length of stay. The percentage of error ranged from 2.22 to 25.Conclusions: Overall, the ACS NSQIP surgical risk calculator very fairly predicted the complications till the 30th post-operative day which naturally matched with actual complications that were seen.
Introduction of a safety checklist for gynecological laparoscopy
Authors: Silva Dhammike , Randombage Prabath , Gankanda Wedisha 
Published: October 2020

This study focuses on the importance of a safety checklist for gynecological laparoscopic surgeries. There is no dedicated safety check list for gynecological laparoscopy although several general safety checklists are used in practice. (e.g. WHO safety check list). The aim was to introduce a safety check list dedicated to gynecological laparoscopy. This check list is based on our experience in performing gynecological laparoscopy in a tertiary care centre with a high workload. This check list is introduced after studying the complications occurring in areas covered by the check list. Present data from 776 cases performed over 4 years at professorial unit in obstetrics and gynecology, university of Sri Jayewardenepura, Colombo South teaching hospital, Kalubowila, Sri Lanka. Mean surgical time and complications associated with patient positioning were assessed. Complications associated with the areas assessed were found to be low. However, it is belief that these can be further reduced by the introduction of a check list specifically designed for gynecological laparoscopy.
