Preliminary test almost unbiased ridge estimator in a linear regression model with multivariate Student-t errors
Authors: Xu Jianwen , Yang Hu
Published: December 2020

In this paper, the preliminary test almost unbiased ridge estimators of the regression coefficients based on the conflicting Wald (W), Likelihood ratio (LR) and Lagrangian multiplier (LM) tests in a multiple regression model with multivariate Student-t errors are introduced when it is suspected that the regression coefficients may be restricted to a subspace. The bias and quadratic risks of the proposed estimators are derived and compared. Sufficient conditions on the departure parameter ∆ and the ridge parameter k are derived for the proposed estimators to be superior to the almost unbiased ridge estimator, restricted almost unbiased ridge estimator and preliminary test estimator. Furthermore, some graphical results are provided to illustrate theoretical results.

Asymmetry in occurrence of the leading and following polarities in the photospheric magnetic field at the early stage of active region formation
Authors: Grigoryev Victor , Ermakova Lyudmila , Khlystova Anna
Published: December 2020

We study the evolution of the photospheric magnetic field at the early stage of active region development. We use data on longitudinal component of the magnetic field and line-of-sight velocities from SOHO/MDI and SDO/HMI. The visual inspection of 48 cases of birth of active regions and the detailed analysis of the magnetic flux dynamics in 4 active regions have shown that at the time of emergence of a new magnetic field, the field of the following polarity is the first to be detected in the photosphere. The flux asymmetry of the leading and following polarities persists for several tens of minutes. The observed asymmetry of magnetic fluxes supports the results of the numerical simulation of emergence of the active region magnetic field in the upper layers of the convective zone, which has been carried out by Rempel and Cheung [2014].
Increases in SCR energetic proton fluxes on Earth and their relation to solar sources
Authors: Lazutin Leonid
Published: December 2020

Logachev catalog data for solar cycle 23 has been used to study the dependence of measured increases in solar cosmic rays (SCRs) on solar perturbations. The efficiency of recording the SCR increases, driven by proton acceleration in the corona, on Earth and in its vicinity is shown to depend on power of a solar flare that created a shock wave and on position of the flare on the solar disk. As the particle flux moves along the heliolongitude away from the parent flare, the acceleration efficiency decreases, i.e. the maximum energy of the accelerated particles and their intensity at equal energy decrease. As a result, at a certain distance along a heliolongitude from the parent solar flare, the solar proton flux intensity decreases to the galactic background, and there is no SCR increase detected.
CONDICIONANTES DE LA REFLEXIÓN EN EL APRENDIZAJE DE LENGUAS EXTRANJERAS
Authors: T. Koch Lennart
Published: December 2020

Desde la Ilustración, las consideraciones en torno a la reflexión se hicieron ex negativo, describiendo sus condicionantes. Al abordar la reflexión en el aprendizaje de lenguas extranjeras, por tanto, no se pueden aplicar las definiciones filosóficas sin preguntarse cuáles son sus condicionantes específicos. En esta contribución se describen tres condicionantes de la reflexión para el aprendizaje de lenguas: 1. La sobrecarga cognitiva lingüística, acompañada del miedo específico a hablar la L2, puede inhibir y frustrar la reflexión en las fases de interlengua; 2. La dificultad de modificar hábitos de aprendizaje relacionados con la propia autoorganización y autopercepción puede frenar o bloquear la reflexión en el aprendizaje; 3. Sin una práctica reflexiva del profesorado será difícil superar ambos condicionantes, pero si se superan, el aprendizaje de lenguas extranjeras probablemente contribuirá a una educación que promueve una reflexión crítica con las creencias de la propia cultura.

Emotional intelligence in palliative medical education
Authors: Tavabie Simon , Bass Steve , Minton Ollie
Published: December 2020

The death of a patient is one of the most stressful situations a healthcare professional can face for the first time at work or during training. Palliative and end of life care education aims to impart appropriate awareness and understanding of key issues arising at the end of life, but also to develop learners' interpersonal skills in leadership, communication and management of their own emotional load. There is a pressing need to be explicit around death, dying and care at the end of life and to equip clinical staff with the ability to manage the emotions that are experienced by their patients, their teams and themselves. Emotional intelligence is considered as a framework for medical educators to use in this setting with presentation of a simulated patient vignette to contextualise this.

The faith of faith-based charity organisations in the voluntary sector
Authors: Service Ryan
Published: December 2020

This paper examines faith’s complex role within faith-based organisations, challenging presumed homogeneity. Through a case study of four projects run by Christian charities in Birmingham, UK, it asks whether religion is performed or managed differently within these organisations. Analysing manager questionnaire responses, three broad themes are considered: religion’s organisational role, prayer, and the presence of religious others and nones. It is hoped that faith-based organisation staff are encouraged to articulate the religious dimension of their projects.

Published: December 2020

Objective: The purpose of this study is to evaluate the influence of the type of scanner and scanning direction on the accuracy of the final cast. Material and Methods: A partial master cast was used as a reference. A total of 128 scans were obtained and divided into two groups: the conventional method and the digital method. The digital group was divided into three groups: TRIOS 3, Omnicam and CS 3600. Each of these groups was subdivided according to the scanning direction, and each scan was overlaid on the digital reference cast to measure the trueness and precision of the procedures. Results: The overall precision values for the type of impression were 59.89 ± 13.08 mm for conventional and 13.42 ± 4.28 mm for digital; the values for trueness were 49.37 ± 19.13 mm for conventional and 53.53 ± 4.97 mm for digital; the scanning direction trueness values were 53.05 ± 4.36 mm for continuous and 54.03 ± 5.52 mm for segmented; and the precision values were 14.18 ± 4.67 mm for continuous and 12.67 ± 3.75 mm for segmented (p> 0.05). For the scanner type, the trueness values were 50.06 ± 2.65 mm for Trios 3, 57.45 ± 4.63 mm for Omnicam, and 52.57 ± 4.65 mm for Carestream; and those for precision were 11.7 ± 2.07 mm for Trios 3, 10.09 ± 2.24 mm for Omnicam, and 18.49 ± 2.42 mm for Carestream (p <0.05). Conclusions: The digital impression method is the most favorable method regarding precision; in terms of trueness, there are no differences between the types of impressions.

Este ensaio apresenta a articulação estabelecida entre duas pesquisas: a de artista e professora de gravura e as de mestrado e de doutorado. A primeira é dedicada às provas de estado, às leituras dos acasos e dos sentidos, do que foi subtraído e ou acrescido (do que se perde e do que se ganha) à imagem impressa mediada pela matriz que a conduziu. A segunda, de maneira análoga, toma o livro impresso como uma matriz que reproduz a escrita e que, mediada por ele, poderá estar também subtraída e ou acrescida de algo. A hipótese de João Guimarães Rosa de que “o livro pode valer pelo muito que nele não deveu caber”, presente no final do prefácio Aletria e Hermenêutica, do livro Tutaméia: terceiras estórias, perpassa ambas as pesquisas indo se encontrar na Biblioteca Para-Luz, obra que, com seus livros vazios, desamarrados e empilhados, abriga e desabriga as imagens do vazio do mundo no mundo do livro.
Comparative Analysis of Machine Learning Techniques for Splitting Identifiers within Source Code
Authors: Abdulsalam Abeer , Rashid Nazre Abdul
Published: December 2020

Feature location is the process of extracting identifiers within source code. In software engineering, it is a usual procedure to upgrade software by adding new features. In order to facilitate this process for the developers, feature location has been proposed to extract the significant components within the source code which are the identifiers. One of the challenging issues that faces the feature location task is handling multi-word identifiers where developers may use different type of separations among the words. Different research studies have used various types of techniques. However, recent studies have showed interest in Machine Learning Techniques (MLTs) due to their substantial performance. With the diversity MLTs, there is a vital demand to identify the most accurate one in terms of splitting the identifiers correctly. Therefore, this study aims to provide a comparative analysis of different MLTs including Naïve Bayes, Support Vector Machine and J48. The dataset used in the experiment is a benchmark data that contains vast amount of source codes along with numerous identifiers. Results showed that the best accuracy has been achieved by using the J48 classifier where the f-measure was 66%.
Ownership and Governance of Central Banks: Insights from the Italian Experience
Authors: Spolaore Piergiuseppe
Published: December 2020

Between the end of 2013 and the beginning of 2014, a radical reform of Banca d’Italia – the Italian central bank and banking supervisory authority – was enacted. It was the last chapter of an historical evolution, started in 1893 with its incorporation as a joint-stock-corporation under private law, whose result places the Italian system within the niche of countries that entail the participation of private investors to the ownership and governance of central banks. This article analyzes the relevant Italian regulation also by comparing it with other international experiences. While most of the debate on central banking independence focuses on independence from politics, this article explores another side of the problem, namely the risk of capture by the banking sector and of subsequent conflicts of interests.Said risk significantly increases when the central bank’s shareholders are private investors which elect some of its governing bodies and receive dividends out of its earnings. Since a central bank carries out monetary operations that generate seigniorage, the distribution of profits out of these earnings is a transfer of public value to the private sector. Such circumstances can create incentives for the owners to influence the central bank’s decisions, also according to the magnitude of the values at stake.
Enhanced diuretic action of furosemide by complexation with β-cyclodextrin in the presence of sodium lauryl sulfate
Authors: Al-Shdefat Ramadan I.
Published: December 2020

Preparation of inclusion complex using cyclodextrins is a well-known formulation strategy to elevate the solubility of drugs. However, often cyclodextrins alone may not bring a considerable improvement in the solubility of low solubility drugs. In this study, the inclusion complexation of furosemide (FSM) was tried with β-cyclodextrin (β-CD) either with the use or without the use of sodium lauryl sulfate (SLS), which is a surfactant. By using the kneading method, the binary complex of FSM/β-CD in the equal molar ratio was used. FSM and β-CD were kneaded continuously until a thick past was achieved, which was evaporated for a period of about 24 h. The solid complexed product was then crushed and stored in airtight container until use. Phase solubility studies confirmed a stoichiometric ratio of 1:1 (FSM/β-CD and FSM/β-CD with SLS). The apparent stability constant and complexation efficiencies of significantly enhanced in the presence of SLS. The prepared complexes were evaluated for DSC, PXRD, 1H NMR, and in vitro release studies. The results exhibited a significant enhancement in diuresis in rats. It is evident that the addition of SLS with β-CD significantly enhances the solubilizing efficiencies and hence bioavailability of FSM.
El horror doméstico en la narrativa breve de Patricia Esteban Erlés y Shirley Jackson
Authors: Calvo Revilla Ana
Published: December 2020

Establecemos un análisis comparativo entre la narrativa breve de la escritora estadounidense Shirley Jackson (1916–1965) y la española Patricia Esteban Erlés (1972–). Fascinadas por las sombras de las historias capaces de evocar el misterio, ambas escritoras alzan unos imaginarios narrativos, en los que la irrupción de lo extraño, lo inesperado y lo incomprensible quiebran y alteran la percepción de la realidad. Nada es lo que parece y bajo la dicotomía mundo infantil – mundo adulto se introducen subrepticiamente lo siniestro y lo macabro en escenarios domésticos. Conscientes de que la cotidianeidad tiene lados oscuros y ángulos inquietantes y de que las mujeres de todos los tiempos han necesitado encarnar sus miedos a través de la creación de criaturas monstruosas y temibles, ambas construyen un imaginario doméstico siniestro.
Numerical investigation of the solutions of Schrödinger equation with exponential cubic B-spline finite element method
Authors: Ersoy Hepson Ozlem , Dag Idris
Published: December 2020

In this paper, we investigate the numerical solutions of the cubic nonlinear Schrödinger equation via the exponential cubic B-spline collocation method. Crank–Nicolson formulas are used for time discretization of the target equation. A linearization technique is also employed for the numerical purpose. Four numerical examples related to single soliton, collision of two solitons that move in opposite directions, the birth of standing and mobile solitons and bound state solution are considered as the test problems. The accuracy and the efficiency of the purposed method are measured by max error norm and conserved constants. The obtained results are compared with the possible analytical values and those in some earlier studies.
Recent History in the Courtroom: Notes on an Experience as an Expert Witness in a Trial for Crimes Against Humanity in Argentina
Authors: Garaño Santiago
Published: December 2020

In this work I reflect on a new figure that has been gaining presence in trials for crimes against humanity since 2005: the “context witness,” a specialist – usually coming from social sciences – who is presented as a witness and whose contribution is taken as testimonial evidence. I rely on my participation in the oral and public trial “Operation Independence,” in which I testified about my doctoral research on the experience of conscripts in southern Tucumán, Argentina between 1975 and 1977. My argument is that social sciences can provide meticulous reconstructions of the logic of repression, helping us to understand how state terror was possible.
The Occupied Territories, Gaza, and Israel’s Recent Slide to Authoritarianism
Authors: Mautner Menachem
Published: December 2020

In recent years there have been numerous warnings in the press and in the social networks that Israel is about to convert its liberal democracy into a fascist regime. This Article argues that the occupation of the West Bank stands at the root of the most important processes that have been taking place in Israel in the past five decades. One of those processes is the erosion of Israel’s liberalism. I claim that the prolongation of the occupation is the central, lasting threat to Israel’s liberalism. In essence, the occupation breeds denunciations of and protests against the government and the Israel Defense Forces, and these, in turn, bring about measures on the part of the government and right-wing civil society organizations that undermine or threaten Israel’s liberalism. In addition, the full-scale wars between Israel and Gaza, and the continuation of violence between the parties in the periods between the wars, undermine or threaten Israel’s liberalism.

Einfach Gott
Authors: Schwöbel Christoph
Published: December 2020

Im vorliegenden Aufsatz wird der Versuch unternommen, die jüngste Diskussion über die Einfachheit Gottes im Zusammenhang der Renaissance trinitarischer Theologie am Ende des 20. Jahrhunderts zu reflektieren. Das aus der Philosophie entlehnte Prinzip der Einfachheit Gottes, das jede Zusammensetzung und jede Differenz von Potenz und Akt aus dem Gottesbegriff ausschließen soll, wird in drei Kontexten betrachtet, in denen jeweils die Beziehungen Gottes zu seiner Schöpfung betont werden: in den biblischen Zeugnissen, im interreligiösen Dialog und im Blick auf das kommunikative Beziehungsgeschehen des Gottesdienstes. Ausgehend von Martin Luthers Verständnis der Trinität als ewiges Gespräch in Gott, das die Schöpfung einbezieht, wird erkundet, ob das Verständnis Gottes als Gespräch im Zusammenhang einer Ontologie kommunikativer Relationen sowohl dem In-Beziehung-Sein Gottes als auch der grammatischen Regel der Einfachheit Rechnung tragen kann.

Do Default Loss Risks Matter for Arab Exports? Evidence from a Gravity Modelling Approach
Authors: Ben Jelili Riadh
Published: December 2020

In the literature, it has been common to use credit risk scores to investigate impacts of external sources of risk and political institutions on foreign investment location choice-decisions. However, only a few studies have specifically examined the relationship between importing country’s credit risk scores and exports. Side stepping the limited availability of statistics on ECAs activities in the Arab countries, this paper investigates empirically the relationship between merchandise exports and credit scores of importing countries. Based on a gravity equation augmented with the risks of default on international payments, measured by intra-country risk ratings, the principal contribution of the present research is to scrutinize the impact of commercial and political risks on merchandise trade in the Arab region. The findings suggest that in the absence of insurance contracts against the risk of defaulting payments, firms are more likely to export to countries with higher prior probabilities to secure payments. It logically follows that provisions of export credit guarantees well targeted towards reducing buyer risks are likely to boost-up exports.

„Alle haben ein Smartphone, nur ich nicht!“
Authors: Wenzl Thomas
Published: December 2020

Der Beitrag geht von der Annahme aus, dass die moderne Gesellschaft durch ein Vermittlungsproblem zwischen dem familialen Binnenraum und dem gesellschaftlichen Allgemeinen gekennzeichnet ist und dass sich dieses Vermittlungsproblem unmittelbar in der familialen Erziehung niederschlägt. Dies wird anhand eines alltäglichen erzieherischen Konflikts herausgearbeitet, in dem Kinder ihren Eltern eine im Vergleich zu anderen Eltern zu ,strenge‘ Erziehung vorwerfen. Durch eine Explikation der sinnlogischen Voraussetzungen von Konflikten dieser Art wird gezeigt, dass sich in ihnen eine ,moralische‘ Schwäche der familialen Erziehung Ausdruck verschafft, die darin besteht, dass Eltern sich in ihrer Erziehung nicht auf allgemein geltende Prinzipien berufen können. Durch eine objektiv hermeneutische Analyse eines Familieninterviews zum innerfamilialen Umgang mit dem Smartphone wird abschließend ein Fall rekonstruiert, der exemplarisch zeigt, in welch hilflose Lage Eltern geraten können, wenn sie sich in ihrer Erziehung nur noch an ihren individuell-partikularen Angemessenheitsvorstellungen orientieren können.
Cytogenetic and oxidative effects of three lichen extracts on human peripheral lymphocytes
Authors: Emsen Bugrahan , Kolukisa Ayse Levent
Published: December 2020

In the present study, we investigated cytogenetic and oxidative [total antioxidant capacity (TAC), total oxidant status (TOS)] effects of methanol and water extracts of Cladonia chlorophaea (Flörke ex Sommerf.) Sprengel, Dermatocarpon miniatum (L.) W.Mann and Parmelia saxatilis (L.) Ach. on cultured human lymphocytes. In addition, different phenolic compounds in the extracts were quantified by high performance liquid chromatography (HPLC) analysis. As a result of HPLC analysis, methanol extracts of all lichen species tested had higher phenolic compounds. Likewise, methanol extracts of each lichen increased TAC levels in lymphocytes more than water extracts. The TOS levels of the cells treated with different concentrations (1–100 mg/L) of the extracts decreased due to the increasing concentration of the extracts. Genotoxicity experiments revealed that the tested lichen extracts did not significantly increase (p > 0.05) the level of genotoxicity on human peripheral lymphocyte culture compared to the negative control group. The results showed that C. chlorophaea, D. miniatum and P. saxatilis lichens, which were found to be a rich source of phenolic compounds, might be of interest in the pharmaceutical and food industries.
Hurricane Style
Authors: Newcomb Matthew J.
Published: December 2020

While hurricanes are weather events that may become human/ecological tragedies, they might help create stylized moments too. Hurricanes can be distinctive from each other in message and in the tools they use as their material aspects (wind speed or storm surge) interact with cities, social structures, and popular media messages. One way to explore hurricane styles is through forms of affective mapping. This exploration analyzes features of several hurricanes that made landfall in 21st-century North America in combination with considerations of affect around hurricanes. The combination of material and affective elements of hurricanes might allow rhetorical style to serve as a way of rethinking hurricanes and their connections, from the individual level to global climate change.

CHANGE MANAGEMENT IN MALAYSIA INFRASTRUCTURE PROJECT: ROLE OF SUBCONTRACTORS
Authors: Lew Yoke-Lian , Ho Zan-Xian , Toh Tien-Choon , Tan Ooi-Kuan , Felicia Yan-Yan-Yong , Yow Li-Ping
Published: December 2020

Implementation of change management is necessary for any construction projects especially infrastructure projects where government allocated billions of ringgit for the country development and the impact of change can be minimised if attended earlier. Nowadays, subcontractors were hired by the contractor to carry out the actual work as subcontracting is a very common practice in this industry. This research was initiated to identify the possible causes of change and then investigated the current status of change management implementation in Malaysia’s infrastructure project. A questionnaire survey was designed to collect data for this research. 102 out of 130 sets of questionnaires were collected from the targeted respondents. Then, a comprehensive analysis was conducted. It was discovered that “design change”, “addition/omission of scopes” and “ambiguities and mistakes in specifications and drawings” were ranked as top three factors contributing to change in Malaysia’ infrastructure projects. This research also discovered that the implementation status of change management was surprisingly high with 72.54% of the infrastructure projects implemented change management. Lastly, the subcontractors’ involvement in contractor’s change management process affected the project performance positively was confirmed in this research as the projects with subcontractor involvement had statistically significant better project performance in terms of time, cost and quality of work. The identification of the root cause for change in infrastructure project helps the future project practitioners to avoid such situation and more well-prepared for it. Subsequently, this research discovered the benefit of practising change management within the infrastructure projects and getting the subcontractor involvement statistically. The findings of this research could improve the project performance of Malaysia’s infrastructure projects.
Vanishing hypercalciuric kidney stones after treating underlying acromegaly
Authors: van der Valk Eline , Tobe Tom , Stades Aline , Muller Alex
Published: December 2020

A 53-year-old male presented with recurrent calcium oxalate kidney stones as a first sign of underlying acromegaly, which vanished when his acromegaly was controlled. The exact mechanism behind hypercalciuria and urolithiasis in acromegaly is not yet clear. By discussing this case, a short overview of the pathophysiology of hypercalciuria in acromegaly and practical insights are given.

Learning points

Hypercalciuria is a common finding in acromegaly.

There are only few reports describing hypercalciuric kidney stones in acromegaly.

We assume that in acromegaly there is a primary role of IGF1-mediated, PTH-independent increase in calcitriol synthesis resulting in hypercalciuric kidney stones.
Sodium vitamin C transporter 2 orchestrates lactate metabolism in mouse Sertoli cells
Authors: Gao Guozheng , Zhao Yong , Wang Ke , Wang Fang
Published: December 2020

Transportation of vitamin C (also called ascorbic acid (AA)), an important water-soluble antioxidant and cofactor in testis, requires glucose transporter family (GLUTs) and sodium/vitamin C cotransporter family (SVCT1 and SVCT2). There is so far scant information vis-à-vis the functional roles of SVCTs in testis, although they possess higher affinity for transportation of AA compared to GLUTs. To analyze the biological effects of SVCT2 in testis, we assessed testicular expression of SVCT2 in different experimental settings and the effect of SVCT2 ablation on spermatogenesis. Persistent expression of SVCT2 was shown in the mouse testis at different stages of postnatal development, demonstrated on day 14 of testicular development in mice consistent with the appearance of pachytene spermatocytes during the first wave of spermatogenesis. Testicular expression of SVCT2 was enriched in the cytoplasm of murine Sertoli cells (SCs). We then showed that in vivo inhibition of SVCT2 in mouse testis significantly impaired male fertility by causing oligozoospermia and asthenospermia, which mainly stemmed from a deficiency in lactate production. By generating the TM4SVCT2−/− cells and by profiling TM4SVCT2−/− cells with a constitutively activated HIF-1α mutant, we demonstrated that SVCT2 deficiency led to impaired lactate synthesis and reduced expression of Ldha mRNA in SCs. Mechanistically, ablation of SVCT2 resulted in ubiquitination and subsequent degradation of HIF-1α protein in the FSH-stimulated SCs. Collectively, our data document a novel testicular site of action of SVCT2 in the control of lactate synthesis by SCs, probably via ubiquitination-dependent regulation of HIF-1α stability.

Aportación al estudio de las formas nominales de tratamiento en el español áureo: condiciones de selección y funciones discursivas
Authors: Iglesias-Recuero Silvia
Published: December 2020

El objeto de este artículo son los tratamientos nominales en las interacciones dialogadas en un corpus formado por seis Entremeses y dos Novelas Ejemplares de Cervantes. En la primera parte, se analizan las condiciones de selección del tipo de TN. Para poder explicar adecuadamente la selección de las formas tanto en las relaciones asimétricas o jerárquicas como, especialmente, en las simétricas en los distintos grupos sociales, se considera necesario incluir otra variable social –el estatus– junto a las ya clásicas del poder y la distancia. Tal variable está asociada al reconocimiento de la identidad y posición social de los individuos, pilar básico de las sociedades estamentales europeas. También se aboga por la conveniencia de tener en cuenta factores discursivos como las restricciones de género y la propia dinámica de la interacción. En la segunda parte, se estudian en el corpus las dos grandes funciones discursivas de los TN en las interacciones conversacionales: la organización y gestión de la conversación y su contribución a la cortesía lingüística y la gestión interrelacional.
MELEZ BİR BASKIRESİM TEKNİĞİ: ON YEDİNCİ YÜZYILDAN ON DOKUZUNCU YÜZYILA MONOTİP
Authors: BALAMBER Burçak
Published: December 2020

Teknik açıdan en basit baskıresim metodu olarak adlandırılabilecek monotip tekniği, sanatçının sadece metal veya cam gibi bir yüzeyi mürekkeplemesini ya da boyamasını, akabinde de monotip baskı elde edebilmek için bu çalışmayı kâğıda transfer etmesini gerektirir. Ağaç baskı, gravür veya litografi gibi geleneksel baskıresim tekniklerinin aksine, monotip tekniği çalışmanın tekrar tekrar mürekkeplenip boyanmasını sağlayacak şekilde bir plaka üzerine kazınması veya kimyasal olarak sabitlenmesini gerektirmez. Yüzey üzerine çizilmiş çalışmanın direkt transferi olarak da özetlenebilecek bu teknik, yalnızca tek bir baskı almayı hedefler.

Bu makalenin amacı, ilk defa kullanıldığı bilinen 17. yüzyıldan ilk defa terimselleştirildiği 19. yüzyıla kadar monotip tekniğinin tarihini keşfetmek ve söz konusu dönemde üretimlerinde monotip tekniğine yer vermiş sanatçıların tekniğe yönelik farklı yaklaşımlarını ele almaktır.

Examining the Use of Expanded Discourse: Treatments of Secondary School Mathematics Teachers' and Preservice Teachers' the Correct Answer
Authors: ERKOÇ Şeyma , YETİM Sebahat
Published: December 2020

The purpose of the study is to examine the extended discourse formed by secondary school mathematics teachers and preservice mathematics teachers in response to the correct answers given by secondary school students to the questions and to reveal whether there is a difference in the expanded discourse styles used by teachers and preservice teachers. The research is a case study; which is one of the qualitative research methods. A measurement form consisting of five correct response scenarios has been developed by the researchers through literature review, and the final form has been given by expert view. Correct answer scenarios have been limited by numbers learning area. Finalized measurement tool has been applied to nine teachers and ten preservice teachers. The qualitative data obtained have been analyzed by content analysis method. According to the results of the analysis, it has been determined that when students give the correct answer to the questions, teachers create a discourse environment by using the types of intervention such as asking students to make more explanations, reward system, asking for different solutions. On the other hand, it has been revealed that the preservice teachers preferred to use the method of forming classroom discussions as well as asking teachers to make explanations, reward system, and asking for different solutions while considering the correct answers of students. It is observed that teachers mostly choose methods appropriate to teacher-centered traditional teaching strategies, while preservice teachers generally use methods appropriate to student-centered research and analysis strategy. Besides, it has been determined that while teachers generally preferred to use a single method, preservice teachers generally used more than one method.
New Urbanism as Urban Political Development: Racial Geographies of ‘Intercurrence’ across Greater Seattle
Authors: Dierwechter Yonn
Published: December 2020

While New Urbanism is now subject to a range of theorizations from different perspectives and disciplinary approaches, it is rarely framed as part of a society’s overall political development. This article explores New Urbanism through recently ‘cosmopolitanized’ and ‘urbanized’ theories of American Political Development (APD). For many years, APD scholars like Skowronek and Orren have emphasized the conceptual importance of ‘intercurrence,’ which refers to the simultaneous operation of multiple political orders in specific places and thus to the tensions and abrasions between these orders as explanations for change. Urban scholars have engaged with these ideas for some time, particularly in studies of urban politics and policy regimes, but APD’s influence on urban planning theory and practice remains underdeveloped. This article takes up this lacuna, applying select APD ideas, notably intercurrence, to understand how multi-scalar governments develop space though New Urbanist theories of place-making, with special attention paid to race. Examples from metropolitan Seattle are used to illustrate (if not fully elaborate) the article’s overall arguments and themes.
Operational Problems in Welded Joints of Flow Sensors Used in Power Engineering
Authors: Pospolita Janusz , Rozumek Dariusz , Polak Janusz , Stano Sebastian
Published: December 2020

The paper presents operational problems present in fluid and gas flow measurement systems. Tests (involving laser welded tubes made using a focused and a defocused beam) were concerned with the quality of welded joints. The tests revealed that the use of the focused beam resulted in the formation of cracks in the welds. In addition, post-weld observations revealed undercuts on the weld face side, responsible for the thinning of the tubes, yet without compromising their service life.

Authors: Machado Ricardo William Guimarães , Ferreira Elisângela de Freitas
Published: December 2020

O interesse pelo tema se concretiza a partir dos debates intermináveis sobre o processo de inclusão na rede básica de ensino no município de Três Rios no Estado do Rio de Janeiro, assim como conhecê-lo na prática, de maneira que possa levar as experiências alcançadas através da pesquisa. Esta será realizada via levantamento bibliográfico e pesquisa a campo, tendo como intuito a maior aproximação com a realidade das crianças com deficiência mental, assim como com os atores que fazem parte dessa trajetória de inclusão. Outro aspecto levado em consideração são os dados obtidos nacionalmente, que enfatizam os crescentes números de crianças portadoras de necessidades mentais que vêm sendo matriculadas nas classes de ensino regular das escolas anualmente. Para além disso a pesquisa tem como objetivo promover o reconhecimento da realidade e das interferências do meio social e ambiental no processo ensino/aprendizado da criança com deficiência mental, bem como trazer os diagnósticos da realidade do aluno com deficiência, e enfim contribuir para os enfretamentos junto as dificuldades no processo de inclusão das crianças com deficiência mental.

Report on the Gynecological Department of the Peter and Paul Hospital for 1896
Authors: Dobbert O. A.
Published: December 2020

The gynecological department that had existed for many years in the Petropavlovsk hospital until 1896 did not, according to modern concepts, have an independent character, since, for reasons not subject to close examination, it was impossible to operate in it. With a few exceptions, all patients who needed surgical aid were transferred to the surgical department. Thanks to the efforts and cares of the Chief Physician A.O. Metzler, since March 1896, the gynecological department has at its disposal an operation and instrumentation that leaves little to be desired and meets all the requirements of anti- and asepsis. It is obvious how essential the latter circumstance is for the separation. Of course, the name of such an operator as K.P.Dombrovsky), who was in charge of the surgical department, attracted at one time quite a few operational cases. On the other hand, however, many patients were frightened by the transfer to an unfamiliar department and another patient, who could be relieved of her suffering with the help of an operation, left the hospital without operational benefits. At present, the appearance of recovering from surgery makes it easier for this or that patient to undergo surgical treatment. I am far from thinking to bow before the operative polypharmacy, but still I cannot but admit the fact that, given the present state of our knowledge, the center of gravity should be shifted to the operative part of gynecology.

Prevention and treatment of cancer using so-called medicinal mushrooms raw materials: Criticism, facts, and perspectives
Authors: Zmitrovich Ivan V. , Vlasenko Vyacheslav A. , Perelygin Vladimir V. , Figurin Igor S.
Published: December 2020

The purpose of the present review is the analysis of modern knowledge on use of medicinal mushrooms metabolites in cancer treatment, including in vitro experiments and clinical studies, with a preliminary assessment of the prospects for the development at least of some tactics of immunotherapy for malignant neoplasms. The data on the efficacy of adjuvant therapy of tumors in combination with mushroom extracts in relation to tumor regression as well as improving overall survival rates are presented. It is postulated that the improvement of long-term results of treatment can be most successfully reached with the use of medicinal mushrooms raw materials. This is due to the fact that an important task after adjuvant therapy (i.e. enhancing the immune surveillance of tumor derivatives) can be successfully solved using polysaccharides of fungal origin. In their final links and targets, such a practice coincides with clinically proven cytokine therapy. The involvement of Russian clinicians in practice of assessment of long-term results of treatment with fungal dectin-stimulation seems to us to be important task of clinical oncology.
