Osman Gâzî’nin 700/1300-1301’de Yenişehir’de Bastırdığı Üçüncü Sikkesi
Authors: YILMAZ Hakan
Published: December 2019

Osmanlılar’ın

“sikke” ve “hutbe” şartlarına dayalı bağımsız bir devlet kurup-kuramadığı

meselesi, 1980’de İbrahim Artuk’un yayımladığı Osman Gâzî’ye ait tarihsiz bir

sikke sayesinde çözümlenmeye başlanmış ise de, sikkenin basit tasarımı ve

ikinci bir örneğinin bulunamaması nedeniyle hakkındaki şüpheler uzun süre devam

etmiştir. Aynı târihlerde ünlü nümismat Nicholas Lowick’in koleksiyonunda yer

aldığı söylenen, ancak okunabilir durumdaki tek yüzünün çizimi dışında hakkında

hiçbir şey bilinmeyen ikinci Osman Gâzî sikkenin ise varlığı kısa bir süre önce

yayınladığımız çok net fotoğrafları sayesinde tamamen aydınlanmış; bu sikkenin

İlhanlı sikkelerine benzer tarzda, diğerinden farklı olarak 699/1300’de

Söğüt’te bastırıldığı ve üzerinde kuruluşun diğer tartışmalı meselelerini de

aydınlatacak çok önemli deliller yer aldığı ortaya çıkmıştır.

Bu

iki meşhur sikkeye ilişkin tespitlerimizi tamamlayacak nitelikteki bu son

araştırmamızda ise, bir kaç yıl önce Alman bir nümismat tarafından

yayınlanmasına rağmen tarih câmiasına meçhûl kalan, Katar’ın başkenti Doha

Müzesi’nde bulunan Osman Gâzî’ye ait üçüncü bir sikke daha bilim dünyâsına

tanıtılarak, bu yeni sikke ışığında Osman Gâzî’nin biat ve istiklâl sürecinin

tamamlanış safhası, Yenişehir Darphanesi’nin kuruluş zamânı ve İlhanlı

hâkimiyetine odaklı bağımsızlık tartışmaları tam anlamıyla sonuçlandırılmaya

çalışılacak; ayrıca son iki sikkenin fiziksel özelliklerinden hareketle Osman

Gâzî’nin ilk sikkesi hakkında da yeni ve önemli tespitler ortaya konulacaktır.

Cumhuriyetin ilk yıllarında toplumsal

kalkınmanın önde gelen hedeflerinden biri de eğitim ve eğitimle iç içe olan

sosyo-kültürel hayatın geliştirilmesi, canlandırılmasıydı. Bu konuda girişilen

müspet çabalar pek çok alanda olduğu gibi sivil toplum örgütlenmelerine de

yansımış, bunun neticesi olarak memleketin her yerinde pek çok dernek ve

cemiyetler teşkil edilmişti. Ankara merkezli olarak “Türkiye Muallimeler ve

Muallimler Dernekleri Birliği” adıyla kurulan Türkiye Muallimler Birliği de

bunlardan bir tanesiydi. Birlik, mevcut adını 1924 genel kongresinde almış ve

Anadolu’nun çeşitli yerlerinde faaliyet gösteren muallim derneklerini de

kendine bağlamıştı. Muallimlerin

yardımlaşma ve dayanışmalarını temin etmek gayesiyle kurulan ve “Türkiye

Muallimler Birliği” çatısı altında faaliyet gösteren bu şubelerden biri de

Bilecik’teki “Ertuğrul Muallimler Birliği” idi.

Ertuğrul

Muallimler Birliği, topladığı kongrelerde aldığı kararlar doğrultusunda ve genç

cumhuriyetin ruhuna yaraşır bir biçimde gerçekleştirdiği hizmet anlayışıyla

eğitimin yaygınlaştırılmasında, eğitim seviyesinin yükseltilmesinde

Bilecik’teki ilim irfan ordusunun canla başla çalıştığı fedakâr bir organizasyon

olarak tarihteki yerini almış ve erken Cumhuriyet Dönemi Bilecik’in sosyal

yaşamında aktif bir rol oynamıştır.

Tanzimat dönemi ile başlayan batı tarzında açılan okullardan biri de lise

dengi olarak açılan idadi mektepleridir. Maarif-i Umumiye Nizamnamesi ile

faaliyetleri belirlenen idadilerde temel amaç Müslüman ve Hristiyan tebaanın kaynaştırılıp

ortak bir kültürde yetiştirilmesi olmuştur. Her ne kadar idadilerin ders

programı ve içerikleri Maarif-i Umumiye Nizamnamesi ile şekillense de bu yeni

okulların mimari düzenlemeleri ile ilgili herhangi bir program

belirlenmemiştir. Vilayet ve sancaklarda Tanzimat Dönemi ile başlayan okul

mimari düzenlemeleri bölgelere göre çeşitli benzerlikler ve farklılıklar

göstermektedir. Son dönem Osmanlı mimarlığı içerisinde değerlendirilen bu yeni

yapılar eklektik yapılar olup içerisinde hem batı tarzı mimari düzenlemeler hem

de klasik unsurlar barındırmaktadır. Bu dönemde inşa edilen idadi yapılarından

biri de Söğüt ilçesinde bulunmaktadır. Söğüt’te bulunan Hamidiye idadisi,

Sultan II. Abdülhamit döneminde inşa edilmiş olup bu yeni mimari anlayışın taşradaki

uygulamalarından biridir.

Bu çalışmanın amacı Söğüt’te bulunan Hamidiye

İdadisinin mimari tanımını yapmak, bugünkü durumlarını malzeme ve süsleme

özelliklerini inceleyerek, Osmanlı devri son dönem mimarisi içindeki yerini

belirlemektir. Bu çalışmada kaynaklar yanında arşiv belgeleri ve günümüze kadar

yapılmış araştırmalara dayanarak Osmanlı mimarisi içinde benzer özellik taşıyan

diğer yapılarla ortak ve farklı özellikleri de mukayese edilecektir.

This study aimed to determine the relationship of the information-seeking behavior of students of ‘Sekolah Menengah Kejuruan Negeri’ (SMKN -Vocational High School) 1, Bandung, with the utilization of Edmodo learning media. This study examined the relationship between the drive for needs, creating change, and environmental activities with the utilization of Edmodo learning media. The method used a correlation study with a quantitative approach. The population in the study were students of class X SMKN 1 Bandung, amounting to 448 people. The sample of this study was 150 people. This research used the information-seeking behavior theory from Krikelas and the concept of Information Technology (IT) Utilization from Thompson. The correlation test analysis technique used Pearson Product Moment (PPM). The results showed that the drive for needs, creating change, and environmental activities, all had a significant relationship with Edmodo learning media. This study concludes that the relationship of information-seeking behavior with the utilization of Edmodo learning media has a low level of closeness. This condition is due to several factors, for Edmodo still functions as a complementary tool and diversity of other learning resources that support student information-seeking activities at SMKN1, Bandung.

Published: December 2019

This paper initially reviews existing empirical models which predict head or pressure increase of two-phase petroleum fluids in electrical submersible pumps (ESPs), then, proposes an alternative model, a fully connected cascade (FCC in short) artificial neural network to serve the same purpose. Empirical models of ESP are extensively in use; while analytical models are yet to be vastly employed in practice due to their complexity, reliance on over-simplified assumptions or lack of accuracy. The proposed FCC is trained and cross-validated with the same data used in developing a number of empirical models; however, the developed model presents higher accuracy than the aforementioned empirical models. The mean of absolute prediction error of the FCC for the experimental data not used in its training, is 68% less than the most accurate existing empirical model.

Estudio del impacto del automodelado y de la autoscopía en la enseñanza de guitarra mediada por tecnología
Authors: Bonifácio Barros Ana Elisa
Published: December 2019

El desarrollo de las tecnologías de la información (TICs) generó expectativas de distribución más democrática de la información (Filatro, 2003). Como forma de adaptación del área de educación a esta nueva realidad, ha expandido la aplicación de herramientas y métodos tecnológicos en los procesos de enseñanza y aprendizaje. Este proceso también incluye el área de educación musical, donde se observa una expansión de investigaciones y de productos direccionados a la enseñanza musical apoyada por tecnologías computacionales. Específicamente en el área de la enseñanza instrumental, el uso de la tecnología no garantiza que la enseñanza del profesor sea correctamente aprehendida por los estudiantes si el alumno no tiene una correcta percepción de su propia performance (APM – Auto Percepción de la Performance). La preocupación por la APM surge en una investigación preliminar denominada Guitarreando (Barros 2017), que en sus resultados arrojó distorsiones en la autopercepción de los sujetos investigados, o sea, una gran diferencia entre lo que los sujetos consideraban haber ejecutado y lo que realmente se ejecutó. Esta discrepancia puede impactar negativamente en el aprendizaje de la guitarra, dado que es difícil desarrollar estudios de ejecución instrumental sin información precisa sobre la autopercepción de la propia ejecución. Con el objetivo de auxiliar en la percepción de la performance musical de estudiantes iniciantes de guitarra, el presente proyecto pretende estudiar el uso de autoscopia y automodelado.
Pseudomonas fluorescens Isolation from Green Salads and Antibiotic Susceptibilities of Isolates
Authors: DÜYÜNCÜ Dilek , ULUSOY Seyhan
Published: December 2019

Currently, leafy green salads are often consumed because they are considered as practical and healthy. However, during their preparation, both inadequate washing and contact with non-hygienic surfaces may increase their microbial load. This may cause several health problems for individuals consuming salads. The overuse of antibiotics has led to the emergence of multidrug resistant bacteria, including foodborne pathogens. Biofilm production ability of these pathogenic bacteria makes it difficult to treat infections caused by these pathogens. The aim of this study is to isolate and identify P. fluorescens from leafy green salads collected from different restaurants. A total of 72 isolates were isolated from leafy green salads, and 29 of these isolates were identified by PCR as Pseudomonas and 9 of them identified as P. fluorescens. All P. fluorescens isolates were resistant to ampicillin, amoxicillin, cefuroxime, ceftazidime and ceftriaxone antibiotics. The results of this study showed that additional attention for the hygiene conditions is needed during the preparation and storage stages of leafy green salads.

Published: December 2019

Bu çalışmada, kurutulmuş enginar çanak yapraklarından üretilen farklı konsantrasyonlarda (%3, 4 ve 5) enginar yaprağı katkılı limonlu soğuk yeşil çayların bazı fizikokimyasal (renk, pH değeri, briks, bulanıklık, titre edilebilir asitlik, toplam fenolik madde miktarı, DPPH ile antiradikal aktivite) ve duyusal kalite karakteristikleri üzerine infüzyon süresinin (5, 7 ve 10 dakika) etkisi incelenmiştir. İnfüzyon süresinin artışıyla birlikte örneklerin parlaklık (L*) ve kırmızılık (a*) değerlerinin azaldığı, sarılık (b*) değerinin ise arttığı görülmüştür. Soğuk çay bileşimindeki enginar konsantrasyonun ve infüzyon süresinin artışına paralel olarak fenolik madde miktarı da artış göstermiştir. Bu artışla birlikte ortamın pH değerinde düşüş, bulanıklık ve titre edilebilir asit miktarında ise artış gözlemlenmiştir. Farklı konsantrasyonlarda enginar infüzyonu içeren soğuk çayların duyusal açıdan herhangi bir olumsuz bir durum oluşturmadığı ve A4 numaralı enginarlı-limonlu soğuk yeşil çayın daha çok tercih edildiği tespit edilmiştir.

Authors: Kaladhar K. , Komuraiah E. , Reddy K. Madhusudhan
Published: December 2019

This analysis is to study the incompressible mixed convection laminar Newtonian flow through concentric cylindrical annulus associated with slip and convective boundary conditions. This presentation considered the cross diffusions and chemical reaction effects also. The fluid flow in an annulus is due to the rotation of the outer cylinder with constant velocity. The analysis of such kind of fluid flow is governed by nonlinear partial differential equations. The governing system of equations were mapped into dimensionless system with appropriate transformations. The system has been solved using Homotopy Analysis Method (HAM). The influence of Soret, Dufour, slip parameter and the chemical reaction parameter on velocity, temperature and concentration are investigated, and presented through plots. The maximum values of slip leads to increase in velocity and temperature profiles. Further the impact of boundary conditions on velocity, temperature and concentration are also presented.

Published: December 2019

In this article, we attain new analytical solution sets for nonlinear time-fractional coupled Burgers’ equations which arise in polydispersive sedimentation in shallow water waves using exp-function method. Then we apply a semi-analytical method namely perturbation-iteration algorithm (PIA) to obtain some approximate solutions. These results are compared with obtained exact solutions by tables and surface plots. The fractional derivatives are evaluated in the conformable sense. The findings reveal that both methods are very effective and dependable for solving partial fractional differential equations.

Published: December 2019

Peripheral artery disease of the lower limbs is, in fact, an arterial pathology, by which the blood flow is reduced, due to the obstruction caused by the deposit of atheroma plaques.(1) This deposition occurs slowly, which leads to a slow progression of the disease, and thus, at the onset of symptomatology. The objective of the study was to make a comparison between the invasive and noninvasive paraclinical investigations performed in patients with peripheral arterial disease of the lower limbs in the E.C.C.H. Sibiu. In conclusion, between the two investigations (computed tomography angiography and digital subtraction angiography) there are no noticeable differences in the terminal aorta and iliac arteries, but in reducing the arteries calibre, the use of digital subtraction angiography is preferred, according to our study, although it is more invasive and exposed to complications.

Authors: Costea Raluca Maria , Maniu Ionela , Neamţu Bogdan
Published: December 2019

Stress hyperglycemia is commonly identified in children with severe illness and previously normal glucose homeostasis. In the pediatric population febrile seizures are reported among stress-related conditions associated with stress hyperglycemia. The objective of this prospective study was to evaluate the possible association between blood glucose level and febrile seizure severity defined by fever degree, seizure type, seizure duration and hospitalization length. Among 167 febrile seizures the prevalence of stress hyperglycemia (blood glucose concentration over 150mg/dl) was 13.22%. There was a highly significant statistical association between seizure duration (exceeding 15 minutes) and increased blood glucose concentration (p= 0.001). Prolonged febrile seizures combined with high fever were significant risk factors for stress hyperglycemia. Further analysis on acute fluctuation of glycemia, persistence of hyperglycemia should be taken in consideration as possible prebdictive factor for stress hyperglycemia, by comparison to the peak blood glucose concentration .

Authors: Nwankwo Cosmas Anayochukwu , Kanyangale Macdonald Isaac
Published: December 2019

The adoption of a market orientation (MO) model for effective management of small and medium enterprises (SMEs) in Nigeria and beyond has drawn diverse views. Extant studies conducted in Nigeria in the past decades have leveraged on the existing entrepreneurial marketing model that has not significantly contributed to the survival of SMEs in Nigeria. The objective of this quantitative study is to investigate the effects of MO on the survival of manufacturing SMEs in Nigeria. The study adopted a positivistic ontology and descriptive survey design. The study randomly selected 387 owner-managers of manufacturing SMEs in Nigeria. The results show that MO significantly contributed to the survival of SMEs in Nigeria. Based on the results, the study recommends that integrative Entrepreneurial Marketing (EM) should be adopted by both the owners and managers of SMEs as this would help reduce the rate of business failure in Nigeria.
Statistical Relations of the Qualitative Attributes of Real Properties Subject to Mass Appraisal
Authors: Dmytrów Krzysztof , Gdakowicz Anna , Putek-Szeląg Ewa
Published: December 2019

Research background: Every real estate may be described with a multitude of attributes. In the process of real estate appraisal only those properties are taken into account that significantly affect its value. Mass appraisal involves a simultaneous valuation of many similar real properties, carried out in the same manner and at the same time. The algorithm applied to mass appraisal ought to ensure a uniform approach to the valuation of all real estate of the same type in an objective fashion.

Purpose: The purpose of the paper is to define the weights of attributes in the process of real estate mass appraisal on the basis of relationships between unit property value and the values of attributes.

Research methodology: The weights were defined on the grounds of partial correlation coefficients for the qualitative properties (Spearman rank correlation coefficient and τB
Kendall correlation coefficient).

Results: The signs of certain correlation coefficients were discordant with the actual direction of the relations between the analysed properties. The problem was avoided by employing partial correlation coefficients. On the basis of the calculated partial correlation coefficients the weights of individual attributes were calculated. Of all analysed coefficients the partial τB
Kendall correlation coefficient is methodologically the most suitable one.

Novelty: The use of partial correlation coefficients for determining attribute weights is an innovative approach and is applied in the article.
Sources of Financing of Household Debt in Poland
Authors: Korzeniowska Anna M.
Published: December 2019

Research background: This paper analyses the inter-relationships between the sources of financing households’ and the debt burden of indebted households.

Purpose: The aim of the paper is to find out inter-relationships between the sources of financing debt and its burden among indebted households.

Research Methodology: The research is divided into two parts. The first represents household debt in Poland in comparison to Euro area countries on the basis of the Households Finance and Consumption Survey. The second analyses are the data collected by the questionnaire at the beginning of 2018 in the Lubelskie voivodeship using the Tau b Kendall coefficient.

Results: The analysis shows that households in the Lubelskie voivodeship focus their debt on financing their housing and consumption needs, whereby the main source of obtaining credit is commercial banks. However, there is a real risk observed in the concentration of loans in parabanks in general and in the need to use low private loans.

Novelty: The findings show that the picture of household debt requires a thorough analysis in different contexts, as from an initial examination the situation looks relatively good, but when analysing more deeply and dividing households into separate groups with similar characteristics, we find considerable varied problems influencing households’ financial situations and raising the risk following their indebtedness.
Cooperation Between Organizations and Consumers – Motivating and Rewarding in the Process of Co-Creation
Authors: Łaszkiewicz Anna
Published: December 2019

Research background: The study examines the degree of the utilization of the idea of co-creating value by companies, taking into account the forms of remuneration of consumers.

Purpose: The paper presents the issue of co-creating value with consumers from the perspective of the motivation and rewarding of clients. The article discusses factors determining the collaboration between the business and the virtual community as well as issues related to the remuneration of consumers.

Research Methodology: The study covered managers who received questionnaires, developed after previous verification in a pilot study. The survey was conducted from August to October 2016. The questionnaire was prepared in a Polish and English version. The questionnaire in the Polish version was completed by 157 participants, while the questionnaire in the English version was completed by 42 managers. In total, 199 questionnaires were registered, including 134 with complete answers, which were subjected to further statistical analysis. The calculations were carried out using the SPSS v. 21/24 package and Statistica v. 7.1.

Results: Enterprises with a high rate of positive answers to questions about the benefits of value creation believe that consumers should work together without remuneration. However, one should remember about the limited value of the interpretation due to the relatively small sample size.

Novelty: This paper focuses on the results of analyses taking into account the relationship between the attitudes of entrepreneurs towards rewarding consumers for their contribution to value creation and the attitudes of entrepreneurs towards the issue of cooperation.
Innovative Procurement in Poland in the Light of the Report on the Evaluation of Public Procurement Functioning after the Amendment of the Public Procurement Law of 2016
Authors: Starzyńska Wacława
Published: December 2019

Research background: Public procurement for innovation has increasingly been the subject of EU policy makers. A lot of changes in the European directives and Polish law have been observed that facilitate the process required for the public procurement of innovation.

Purpose: The purpose of the paper is an attempt to study a functioning public procurement system as a sourcing mechanism for innovative products and services in Poland.

Research Methodology: Review of the existing legislation concerning public procurement especially the Public Procurement Law in Poland after its amendment of 2016 and analysis of the results of a survey conducted among contracting entities and contractors of public procurement.

Results: The empirical study suggests that there is a deficit of knowledge of both contracting entities and contractors, concerning awareness and application of legal provisions facilitating procuring innovative products. The existing scale of innovative solutions’ application by contracting entities is very low, resulting from a lack of needs or due to the business profile, which does not contribute to increasing the demand for innovative products.

Novelty: There is a lack of similar investigations in the Polish and European literature. It is worth stressing that public procurement viewed as a special case of innovation which is distinct from the procurement of a regular market. The empirical results are based on a study conducted in 2018 by the Public Procurement Office in Poland.
Management Control Systems and Innovation Process Efficiency. A Conceptual Model
Authors: Szutowski Dawid
Published: December 2019

Research background: There seem to be a research gap concerning the relation between management control and innovation. Previous research in the field has generated inconclusive findings.

Purpose: The purpose of the present study was to create a conceptual model representing the relation between management control and innovation.

Research methodology: The study relied on a systematic literature review. The initial search yielded 269 papers, which were later analysed and reduced to select those with a substantial contribution to the purpose of the study. Next, the meta-synthesis method was employed to create a thematic map and extract information from the papers.

Results: The formulated conceptual model indirectly links management control systems to innovation process efficiency through decision-making quality. Furthermore, it connects management control systems indirectly to decision-making quality, through the transactive memory system (specialisation, building credibility and coordination) and shared interpretation schemes. The link between decision-making quality and innovation process efficiency is introduced and based on the concept of an innovation process.

Novelty: The paper fills in the missing link between management control and innovation by introducing decision-making quality into this context.
Masked Sentence Model Based on BERT for Move Recognition in Medical Scientific Abstracts
Authors: Yu Gaihong , Zhang Zhixiong , Liu Huan , Ding Liangping
Published: December 2019

Purpose

Move recognition in scientific abstracts is an NLP task of classifying sentences of the abstracts into different types of language units. To improve the performance of move recognition in scientific abstracts, a novel model of move recognition is proposed that outperforms the BERT-based method.

Design/methodology/approach

Prevalent models based on BERT for sentence classification often classify sentences without considering the context of the sentences. In this paper, inspired by the BERT masked language model (MLM), we propose a novel model called the masked sentence model that integrates the content and contextual information of the sentences in move recognition. Experiments are conducted on the benchmark dataset PubMed 20K RCT in three steps. Then, we compare our model with HSLN-RNN, BERT-based and SciBERT using the same dataset.

Findings

Compared with the BERT-based and SciBERT models, the F1 score of our model outperforms them by 4.96% and 4.34%, respectively, which shows the feasibility and effectiveness of the novel model and the result of our model comes closest to the state-of-the-art results of HSLN-RNN at present.

Research limitations

The sequential features of move labels are not considered, which might be one of the reasons why HSLN-RNN has better performance. Our model is restricted to dealing with biomedical English literature because we use a dataset from PubMed, which is a typical biomedical database, to fine-tune our model.

Practical implications

The proposed model is better and simpler in identifying move structures in scientific abstracts and is worthy of text classification experiments for capturing contextual features of sentences.

Originality/value

T he study proposes a masked sentence model based on BERT that considers the contextual features of the sentences in abstracts in a new way. The performance of this classification model is significantly improved by rebuilding the input layer without changing the structure of neural networks.
Identification of Sarcasm in Textual Data: A Comparative Study
Authors: Mehndiratta Pulkit , Soni Devpriya
Published: December 2019

Purpose

Ever increasing penetration of the Internet in our lives has led to an enormous amount of multimedia content generation on the internet. Textual data contributes a major share towards data generated on the world wide web. Understanding people’s sentiment is an important aspect of natural language processing, but this opinion can be biased and incorrect, if people use sarcasm while commenting, posting status updates or reviewing any product or a movie. Thus, it is of utmost importance to detect sarcasm correctly and make a correct prediction about the people’s intentions.

Design/methodology/approach

This study tries to evaluate various machine learning models along with standard and hybrid deep learning models across various standardized datasets. We have performed vectorization of text using word embedding techniques. This has been done to convert the textual data into vectors for analytical purposes. We have used three standardized datasets available in public domain and used three word embeddings i.e Word2Vec, GloVe and fastText to validate the hypothesis.

Findings

The results were analyzed and conclusions are drawn. The key finding is: the hybrid models that include Bidirectional LongTerm Short Memory (Bi-LSTM) and Convolutional Neural Network (CNN) outperform others conventional machine learning as well as deep learning models across all the datasets considered in this study, making our hypothesis valid.

Research limitations

Using the data from different sources and customizing the models according to each dataset, slightly decreases the usability of the technique. But, overall this methodology provides effective measures to identify the presence of sarcasm with a minimum average accuracy of 80% or above for one dataset and better than the current baseline results for the other datasets.

Practical implications

The results provide solid insights for the system developers to integrate this model into real-time analysis of any review or comment posted in the public domain. This study has various other practical implications for businesses that depend on user ratings and public opinions. This study also provides a launching platform for various researchers to work on the problem of sarcasm identification in textual data.

Originality/value

This is a first of its kind study, to provide us the difference between conventional and the hybrid methods of prediction of sarcasm in textual data. The study also provides possible indicators that hybrid models are better when applied to textual data for analysis of sarcasm.
Are Contributions from Chinese Physicists Undercited?
Authors: Guo Jinzhong , Liu Xiaoling , Yang Liying , Wu Jinshan
Published: December 2019

Purpose

In this work, we want to examine whether or not there are some scientific fields to which contributions from Chinese scholars have been under or over cited.

Design/methodology/approach

We do so by comparing the number of received citations and the IOF of publications in each scientific field from each country. The IOF is calculated from applying the modified closed system input–output analysis (MCSIOA) to the citation network. MCSIOA is a PageRank-like algorithm which means here that citations from the more influential subfields are weighted more towards the IOF.

Findings

About 40% of subfields in physics in China are undercited, meaning that their net influence ranks are higher (better) than the direct rank, while about 75% of subfields in the USA and German are undercited.

Research limitations

Only APS data is analyzed in this work. The expected citation influence is assumed to be represented by the IOF, and this can be wrong.

Practical implications

MCSIOA provides a measure of net influences and according to that measure. Overall, Chinese physicists’ publications are more likely overcited rather than being undercited.

Originality/value

The issue of under or over cited has been analyzed in this work using MCSIOA.
Two new species of the genus Scathophaga (Diptera: Scathophagidae) from Svalbard, with a key to selected northern species and comments on their taxonomy
Authors: Šifner František
Published: December 2019

Two new Palaearctic species, Scathophaga annae sp. nov. and Scathophaga simaceki sp. nov. are described from Svalbard. An illustrated identification key for selected northern species from of the genus Scathophaga from the Palaearctic and Nearctic Regions is given. Two new combinations are provided: Coniostenum molle (Becker, 1894) comb.nov. for Scathophaga mollis (Becker, 1894) and Coniosternum nigripalpis (Becker, 1907) comb. nov. for Scathophaga nigripalpis (Becker, 1907). Two new synonyms are established, Scathophaga (Coniosternum) sychevskaye Ozerov, 2010, syn. nov. = Coniosternum molle and Scathophaga minuta (Maloch, 1935), syn. nov. = Coniosterum lapponicum Ringdahl, 1920. Scathophaga islandica (Becker, 1894) and Scathophaga villipes (Zetterstedt, 1846) are confirmed as valid species. The species Scathophaga furcata (Say, 1823) is confirmed again in this area. Scathophaga janmayeni (Séguy, 1939) is species incertae sedis. Scathophaga islandica (Becker, 1894) is first recorded from Greenland and Sweden (Lappland).
Julia Hufnagel-Schildbach (1880–1962) – the most significant woman – collector of minerals in Bohemia and her collection at the National Museum in Prague
Authors: Bohatý Martin , Velebil Dalibor
Published: December 2019

Julia H. Schildbach (*1880, †1962) from Marienbad (Mariánské Lázně) built around 1900–1935 an extensive systematic collection of minerals. Minerals were bought, exchanged and personally collected at localities in the wide vicinity of Mariánské Lázně. She had extensive contacts with collectors of minerals in Bohemia and Germany and professional mineralogists in Austria and Bohemia, including mineralogists from the National Museum in Prague. After the end of World War II, she was not evicted as a German from Marienbad, unlike other German inhabitants, but lived in her home town until she died. However, her collection of minerals was confiscated by the state after the war. The larger part of the collection has been transferred to the National Museum in Prague, where 2716 items of minerals from the collection of J. Schildbach are registered, and part of the collection has been transferred to the Municipal Museum in Mariánské Lázně.
Two rare spider species (Araneae: Araneidae, Theridiidae) found in the Šumava Mts.
Authors: Dolejš Petr , Rückl Kryštof
Published: December 2019

During an arachnological survey in the Šumava National Park in 2016, two very rare spider species were discovered: Araneus saevus (Araneidae) was recorded for the second time, 45 years after its first report in the Czech Republic. The species is therefore no longer regionally extinct, and can be considered critically endangered. Theridion boesenbergi (Theridiidae) was recorded for the first time in the Šumava Mts. Ecological characterisation of the species is improved, being more psychrophilous than was previously expected. Almost all collected specimens of both species from the Czech Republic are deposited in the National Museum in Prague.

The soil is a key component of natural ecosystems because environmental sustainability depends largely on a sustainable soil ecosystem. The objective of this study was to predict the impact of selected toxic compounds from dumpsite or contaminated soils on human health at the molecular level of biological processes. Thein silicomethods that were used include toxicokinetics and target gene prediction, molecular docking, and gene expressing network analysis. The result showed bisphenol A (BPA), 2,20-bis(p-chlorophenyl)-1,1-dichloroethane (DDD), 2,20-bis(p-chlorophenyl)-1,1-trichloroethane (DDT), diethylhexyl phthalate (DEHP), nonylphenol (NP) and tetrachlorodibenzodioxin (TCDD) as the active toxic compounds that can modulate biological system and are considered as potential cause of several diseases including cancer. The principal target genes include substance-P receptor (also known as Neurokinin 1 receptor), 5-hydroxytryptamine receptor, human serotonin transporter; estrogen receptor alpha; and aryl hydrocarbon receptor. These genes implicated SUZ12, STAT3, and TRIM28 as the major transcription factors while mitogen-activated protein kinases and cyclin-dependent kinases were the major kinases from the protein-protein interaction. All the six toxicants investigated showed good free binding energies (ΔG) which were below - 5.0 kcal.mol−1. These toxic compounds showed ligand efficiency greater than 0.25 kcal.mol−1. HA and would possibly cause fatal damage on human health. The order ofin silicopredicted toxicity of these compounds were BPA > DDD = DDT > TCDD > NP > DEHP. Our results identified potential threats, which the selected toxicants can pose to public health. More importantly, it provides basis for investigation of super bugs (microorganisms) that can remediate these toxicants in our environment. Environmental monitoring and modern wastes management system should be implemented and enforced in the affected countries in order to safeguard the health of the citizenry.

Published: December 2019

The present work examines the influence of the leaching conditions on the release of various chemical elements from a cementitious material obtained by solidification of an industrial waste rejection of Algeria. Toxicity Characteristic Leaching Procedure (TCLP), X-ray diffraction (XRD) and Scanning electron microscopy coupled with energy dispersive X-ray microanalysis SEM-EDX analyses were employed to characterize the waste and the stabilized/solidified materials. Than several formulations were prepared with different percent of waste ranging from 0 % to 30 %. To evaluate the influence of leaching conditions on the release of chemical ions (Zn2+, Pb2+, Cl-, Mg2+, Ca2+, Na+, K+ and SO42−) contained in the stabilized and solidified materials, the Acid Neutralization Capacity (ANC), the Pore Water (PW) and Monolith Leaching Tests (MLT) have been carried out. The leaching tests (ANC, PW and MLT) have shown a low metal leachability. However, the lowest released amount was observed for the MLT.
