The Linguistic and Cultural Atlas of Immigration: Multidisciplinary Research for Spanish Classrooms
Authors: del Carmen Fernández López María 
Published: December 2019

AbstractThis study presents a model for researching the integration of the immigrant population in educational contexts based on a multidisciplinary approach.The Linguistic and Cultural Atlas of Immigration(ALCI) is a working tool designed for teachers who must serve students in their classrooms from languages and cultures other than that of instruction. The information the Atlas contains is the product of various research and documentation projects on the demographic variables of the foreign population located in central Spain, the habits and customs of their culture of origin and important aspects of their native, family or heritage language. The ALCI raises awareness of the results of linguistic and cultural research carried out with the collaboration of the immigrant population (students, their families and other participating adults) and teachers, so that they can be leveraged and employed in the classroom.
Die kulturelle Norm der Kernfamilie – Habitusrekonstruktionen und Deutungsmusteranalyse
Authors: Funcke Dorett 
Published: December 2019

Zusammenfassung
In diesem Beitrag geht es um eine unkonventionelle Familienform, die gleichgeschlechtliche Familie, und die Frage: Welche sozialisatorischen Voraussetzungen führen dazu, dass trotz Geltung der Norm der Kernfamilie, die im ausgewählten Fall sich im Vollzug von Deutungen empirisch manifestiert, von dieser Regelstruktur abgewichen wird. Die Abweichung zeigt sich in der Wahl einer anonymen Samenspende und darin, dass die Nachwuchssozialisation vom Muster der Kernfamilie abgetrennt ist. Grundlage der Fallrekonstruktionsanalyse sind das Genogramm und eine ausgewählte Sequenzstelle aus dem Interview. Der Beitrag schließt mit allgemeinen Überlegungen zur sozialen Wirklichkeit von alternativen Familien und mit familientheoretischen Reflexionen.
Erziehung unter Druck
Authors: Wolf Eike 
Published: December 2019

Zusammenfassung
Der Beitrag befasst sich mit der Interdependenz des dualistischen Ordnungsschemas von Privatheit und Öffentlichkeit der Erziehung aus mikrologischer Perspektive. Mithilfe der interaktionstheoretischen Terminologie Goffmans wird der Einfluss öffentlicher Interaktionsstrukturen auf privates Erziehungshandeln verdeutlicht und mittels der objektiv hermeneutischen Rekonstruktion eines entsprechenden Falls empirisch abgesichert. Die begrifflich-dualistisch operierenden Ordnungskategorien von öffentlicher und privater Erziehung werden so als klassifikatorische Idealtypik zur Handlungsbeschreibung gefasst, die sich empirisch erst anhand geltender Interaktionsordnungen relationieren lassen. Als zentrales Strukturproblem für unter den Bedingungen von Öffentlichkeit sich vollziehende Erziehungspraxis wird die triadische Interaktions-struktur zwischen Erziehungs-Dyade und Öffentlichkeit gefasst.
Positionalität zwischen Sein und Noch-nicht-Sein
Authors: Rademacher Sandra , Tressat Michael 
Published: December 2019

Zusammenfassung
Ausgehend von der Frage, was es bedeutet, als Kind und Jugendlicher in einem spezifischen Sozial- und Kulturraum positioniert zu sein und sich zugleich von eben dieser Positionalität ausgehend als (kindliches und jugendliches) Subjekt entwerfen und positionieren zu müssen, analysieren wir in diesem Beitrag aus entwicklungs- und sozialisationstheoretischer Perspektive fotografische Selbstporträts eines neunjährigen Mädchens aus Deutschland und eines dreizehnjährigen Jungen aus Ghana. Als heuristischen Rahmen für „Kindheit“ und „Jugend“ entwerfen wir das Konzept eines dialektischen Spannungsverhältnisses zwischen Sein und Noch-nicht-Sein, das wir als konstitutiv für die Positionalität von Kindern und Jugendlichen erachten. Bei der Analyse betrachten wir daher besonders die Art und Weise, wie sich Positionalität und Position des Fotografierenden in einem fotografischen Protokoll niederschlagen. Die beiden Fallanalysen zeigen, dass dieses Spannungsverhältnis insbesondere im Übergang von der Kindheit zur Jugend thematisch ist und dass Spiegel-Selfies dieses Spannungsverhältnis eines „Zwischenraumes“ geradezu idealtypisch zum Ausdruck bringen.
The location of classified edges due to the change in the geometric multiplicity of an eigenvalue in a tree
Authors: Toyonaga Kenji 
Published: December 2019

Abstract
Given a combinatorially symmetric matrix A whose graph is a tree T and its eigenvalues, edges in T can be classified in four categories, based upon the change in geometric multiplicity of a particular eigenvalue, when the edge is removed. We investigate a necessary and sufficient condition for each classification of edges. We have similar results as the case for real symmetric matrices whose graph is a tree. We show that a g-2-Parter edge, a g-Parter edge and a g-downer edge are located separately from each other in a tree, and there is a g-neutral edge between them. Furthermore, we show that the distance between a g-downer edge and a g-2-Parter edge or a g-Parter edge is at least 2 in a tree. Lastly we give a combinatorially symmetric matrix whose graph contains all types of edges.
Numerical construction of structured matrices with given eigenvalues
Authors: Sutton Brian D. 
Published: December 2019

Abstract
We consider a structured inverse eigenvalue problem in which the eigenvalues of a real symmetric matrix are specified and selected entries may be constrained to take specific numerical values or to be nonzero. This includes the problem of specifying the graph of the matrix, which is determined by the locations of zero and nonzero entries. In this article, we develop a numerical method for constructing a solution to the structured inverse eigenvalue problem. The problem is recast as a constrained optimization problem over the orthogonal manifold, and a numerical optimization routine seeks its solution.
Extensions of the Eneström-Kakeya theorem for matrix polynomials
Authors: Melman A. 
Published: December 2019

Abstract
The classical Eneström-Kakeya theorem establishes explicit upper and lower bounds on the zeros of a polynomial with positive coefficients and has been generalized for positive definite matrix polynomials by several authors. Recently, extensions that improve the (scalar) Eneström-Kakeya theorem were obtained with a transparent and unified approach using just a few tools. Here, the same tools are used to generalize these extensions to positive definite matrix polynomials, while at the same time generalizing the tools themselves. In the process, a framework is developed that can naturally generate additional similar results.
Martensitic Steel Microstructure Effects on Cavitation Erosion
Authors: Ylönen Markku , Nyyssönen Tuomo , Honkanen Mari , Peura Pasi 
Published: December 2019

Abstract
Cavitation and cavitation erosion are sometimes unavoidable phenomena in hydro machine operation. For example, operating hydro turbines as regulating power leads to situations in which the risk of cavitation is accepted to some extent. Cavitation-resistant materials are therefore required to reduce machine damage and maintenance. This study characterizes the microstructure of two martensitic stainless steels from Francis turbines. They were already studied for cavitation erosion resistance in a previous study, and this study reveals the reasons behind the other steel having a significantly better resistance, while they had similar chemical compositions. The electron backscatter diffraction (EBSD) method is effective in defining the martensitic microstructure, specifically the block, packet, and prior austenite grain level. In addition, the retained austenite is effectively detected with the method. A fine prior austenite grain size and small packet and block sizes were found to be among the defining factors in cavitation erosion resistance of these steels. In addition, the transformation of retained austenite to martensite was detected in the edge region where cavitation had taken place. This transformation further increases cavitation erosion resistance. The better resistance of Steel 1 against cavitation was attributed to these microstructural differences. According to these findings, the microstructure in Steel 1 would be highly beneficial in building cavitation erosion resistant hydro machines and would be of interest to manufacturers of martensitic stainless steel components.
Genetic Control and Geo-Climate Adaptation of Pod Dehiscence Provide Novel Insights into Soybean Domestication
Authors: Zhang Jiaoping , Singh Asheesh K 
Published: December 2019

Abstract
Loss of pod dehiscence was a key step in soybean [Glycine max (L.) Merr.] domestication. Genome-wide association analysis for soybean shattering identified loci harboring Pdh1, NST1A and SHAT1-5. Pairwise epistatic interactions were observed, and the dehiscent Pdh1 overcomes resistance conferred by NST1A or SHAT1-5 locus. Further candidate gene association analysis identified a nonsense mutation in NST1A associated with pod dehiscence. Geographic analysis showed that in Northeast China (NEC), indehiscence at both Pdh1 and NST1A were required in cultivated soybean, while indehiscent Pdh1 alone is capable of preventing shattering in Huang-Huai-Hai (HHH) valleys. Indehiscent Pdh1 allele was only identified in wild soybean (Glycine soja L.) accession from HHH valleys suggesting that it may have originated in this region. No specific indehiscence was required in Southern China. Geo-climatic investigation revealed strong correlation between relative humidity and frequency of indehiscent Pdh1 across China. This study demonstrates that epistatic interaction between Pdh1 and NST1A fulfills a pivotal role in determining the level of resistance against pod dehiscence, and humidity shapes the distribution of indehiscent alleles. Our results give further evidence to the hypothesis that HHH valleys was at least one of the origin centers of cultivated soybean.

Relationship between Paraoxonase-1 and Arylesterase Enzyme Activities and SYNTAX I and II Scores in Patients with ST-Elevation Myocardial Infarction
Authors: Sökmen Erdoğan , Çelik Mustafa , Sivri Serkan , Güçlü Kenan 
Published: December 2019

Background: Although serum paraoxonase-1 (PON-1) and arylesterase (ARE) activities are linked to the presence of stable coronary arterial disease, their correlation with SYNTAX Score I (SS1) and SYNTAX Score II (SS2) has not been known well. Our aim was to determine the association between PON-1 and ARE activities, together with the genetic polymorphism of PON-1, and both SS1 and SS2 in patients with acute ST-segment elevation myocardial infarction (STEMI).
Methods: Consecutive patients with acute STEMI (n=102: 78 male, 24 female; mean age=61.14±12.25 y) admitted to the Emergency Department of Kırşehir Ahi Evran University Hospital between August 2018 and December 2018 were enrolled. PON-1 and ARE activities were determined on hospital admission. The SS1 and SS2 scores were calculated by using the angiographic and clinical data. Subsequently, the relationships between the activities of the enzymes, together with the genetic polymorphism of PON-1, and both SS1 and SS2 were interrogated.
Results: The mean SS1 and the mean SS2 were 19.8±9.7 and 32.3±11.5, respectively. The phenotype distributions of PON-1 were Q192Q (n=60), R192Q (n=35), and R192R (n=7). The respective PON-1 (U/L) and ARE (kU/L) activities were 514.85±29.34 and 216.82±36.72 in the low SS1 category; 527.60±56.31 and 203.95±55.97 in the intermediate SS1 category; and, 690.10±11.07 and 238.48±45.65 in the high SS1 category.PON-1 and ARE activities did not correlate with the SS1 categories, and varying SS2 scores. The distribution of the Q192R polymorphism was homogenous among the different SS1 and SS2 scores. The localization of acute STEMI also did not associate with the activities of either enzyme.
Conclusion: Admission serum PON-1 and ARE activities, together with the PON-1 Q192R genetic polymorphism, showed association neither with SS1 and SS2 nor with the localization of infarction in our acute STEMI patients.

Use of the Left Ventricular Internal Dimension at End-Diastole and the E-Point Septal Separation Ratio in the Prediction of the Left Ventricular Systolic Function in Patients with Midrange and Reduced Ejection Fractions: A Pilot Study
Authors: Cosansu Kahraman , Kilic Harun , Cabbar Ayca Turer , Hatipsoylu Erdinc , Karadag Bilgehan , Akdemir Ramazan 
Published: December 2019

Background: The aim of this study was to investigate the ability of a new index, namely the left ventricular internal dimension at end-diastole/mitral valve E-point septal separation (LVIDd/EPSS), to predict the left ventricular (LV) systolic function and to compare its performance with that of the EPSS index and to investigate the correlation between the LVIDd/EPSS and the left ventricular ejection fraction (LVEF).
Methods: The current study recruited 142 patients who presented to the Cardiology Clinic of Sakarya University Education and Research Hospital and were followed for heart failure (HF).M-mode measurements of the EPSS and the LVIDd were recorded in the parasternal long-axis view.
Results: Totally, 142 HF patients with midrange ejection fraction (HFmrEF) and reduced ejection fraction (HFrEF) were enrolled in the study. There was a significantly correlation both between the EF and the EPSS and between the EF and the LVIDd/EPSS (P<0.001). In both HFmrEF and HFrEF groups, the correlation between the LVIDd/EPSS and the EF was more significant than was the correlation between the EPSS and the EF (P<0.001). The results of the linear regression analysis indicated that the LVIDd/EPSS was an independent predictor of the HFmrEF and the HFrEF (P<0.001). In the patients with EPSS≤12, there was a significant association between the EF and the LVIDd/EPSS (P<0.001) but not between the EF and the EPSS(P>0.05). The receiver operating characteristic curve analysis showed that the LVIDd/EPSS predicted advanced HF with 87% sensitivity and 72% specificity, using a cutoff value of 3.35,and it predicted the HFrEF (EF<40%) with 84% sensitivity and 81% specificity, using a cutoff value of 3.75.
Conclusion: The LVIDd/EPSS may allow certain clinicians, especially beginners and emergency department physicians, to assess the LVEF when other methods are not available or questionable­.

Authors: Khosravi Mohammad Bagher , Kahrom Mahdi , Tahari Mahdi , Alizadeh Kambiz , Soltani Ghasem , Ghanad Mohammad Ali 
Published: December 2019

Background: Ischemic postconditioning is a novel strategy for attaining cardioprotection. Remarkable evidence from various in vitro and in vivo animal and human studies have shown significant opioid-induced cardioprotection against myocardial ischemia/reperfusion (I/R) injury. The purpose of this study was to assess the cardioprotective effect of sufentanil against I/R injury after on-pump coronary artery bypass grafting (CABG).
Methods: Between June 2016 and July 2017, 80 consecutive patients with triple-vessel disease undergoing on-pump CABG were enrolled in this prospective randomized study. The patients assigned to the sufentanil group received a single dose of sufentanil (0.2 μg/kg diluted with 50 cc of saline) 5 minutes before the removal of the aorta cross-clamp, with the sufentanil injected via a cardioplegia needle into the aortic root. In the control group, the same volume of normal saline was injected as a placebo. Cardiac enzymes, the inotrope score, and the outcome data were compared between the 2 groups.
Results: The mean age of the patients was 60.48±7.50 years (range=41–69 y), and men comprised 65.0% of the study population. The levels of CK-MB and cardiac troponin I were significantly lower in the sufentanil group (P<0.001). The amount of inotrope use (P<0.001), the incidence of atrial fibrillation (P=0.014), electrical shock (P=0.007), and the mechanical ventilation time (P<0.001) decreased in the sufentanil group compared with the control group. However, the use of intra-aortic balloon pumps (P=0.247) and the ICU length of stay (P=0.867) were not significantly different between the 2 groups.
Conclusion: The injection of a single dose of sufentanil into the aortic root prior to aorta cross-clamp removal diminished cardiac injury during on-pump CABG in our patients.

Acute Dissection of the Ascending Aorta as a Rare Complication of Aortocoronary Bypasses Surgery: A Case Report
Authors: Borulu Ferhat , Erkut Bilgehan 
Published: December 2019

Many complications may ensue coronary bypass surgery. Among these complications, early or late dissection of the ascending aorta is a very rare condition. Successful surgery without life-threatening results can save lives. In this case report, we present a case of aortic dissection due to cross-clamp injury in a patient who underwent coronary artery bypass surgery.
A 60-year-old female patient underwent double-vessel aortocoronary bypass surgery due to coronary artery disease. After distal bypasses were performed and the cross-clamp was removed, dissection of the aorta occurred. Consequently, axillary cannulation and ascending aortic replacement with a prosthetic graft were performed via the open technique. The saphenous vein graft was sutured to the aortic prosthetic graft, and cardiopulmonary bypass was terminated after hemodynamic stability was achieved. The patient was discharged on the 10th postoperative day, and she has been followed up for 2 years after surgery without any problems.

Authors: Zareei Mahmoodabadi Hassan , Ghazi kermani Fateme , Ehrampoush Mahsa 
Published: December 2019

Introduction: Increase of job satisfaction and reduction of job burnout are among the most challenging concepts in the field of occupation / organization. They are also considered as the basis of many policies to increase the productivity and efficiency of an organization. One of the most important causative factors of burnout is personality traits. In this context, schemas, as the personality traits described in personality development psychology, play a significant role. Therefore, investigating the relationship between these transformational patterns and occupational burnout can be considered as an essential issue in the field of occupational healthMethods: This descriptive study was conducted on 220 personnel of Public Health School in Yazd Shahid Sadoughi University of Medical Sciences. The participants were selected using simple random sampling method and the data were collected using the Maslach Job Burnout Questionnaire and the Young Short-form Short-Scale Questionnaire. Data were analyzed using Spss 20 by applying the central tendency indicators, t-test, and Pearson's correlation coefficient to test the hypotheses.Results: The results of this study showed a negative but significant relationship between most of the early maladaptive schemas and the two subscales of burnout (emotional exhaustion and depersonalization). The results also showed a positive and significant relationship between the schema score of release / instability and individual performance (r = 0.206, p-value = 038.Conclusion: According to the results of our study, it can be said that some of the areas of early maladaptive schemas cause stress in the university personnel and repetition of these stresses causes burnout. Therefore, understanding these areas and planning to prevent and control them are practically required to promote organizational productivity in the field of occupational and industrial research.

Authors: Rahimi Pordanjani Tayebe , Mohammadzadeh Ebrahimi Ali 
Published: December 2019

Introduction: Job satisfaction is considered as an important factor for increasing efficiency and individual satisfaction in the organization. The purpose of this study was to test the structural model of positive organizational behavior and job satisfaction with the mediating role of job stressors.
Methods: The present study was a cross-sectional and correlational study using structural equation modeling (SEM). The sample consisted of 165 employees that working in university of Bojnord, who were selected by simple random sampling method. Participants in this study were measured using occupational stress, job satisfaction and positive organizational behavior questionnaires. Reliability and validity all of the questionnaires were accepted. Structural equation modeling (SEM) through Amos-23 and SPSS-23 software packages was used for data analysis. In addition, Bootstrup was used for testing mediation.
Results: The results showed that the proposed model fits the data properly. Positive organizational behavior has a direct effect on job satisfaction and job stressors (p<0.0001). Also, the mediating effect of job stressors in the relationship between positive organizational behavior and job satisfaction was confirmed (p<0.0001).
Conclusion: Organizations can increase their job satisfaction by reducing job stressors and training and reinforcing positive organizational behaviors of their employees.
