Effects of Psychological and Cognitive Factors on the Relation between Entrepreneurial Intention and Academic Hazing: Case of the New Students in the Faculty of Social and Human Sciences at the University of Beira – Portugal
Authors: Garcez Ana , Franco Mário 
Published: June 2021

Abstract
This study aims to (1) analyse whether university students’ psychological and cognitive factors influence the entrepreneurial intention and integration in academic hazing, and (2) assess the effect the entrepreneurial intention may have on integration in academic hazing. Using a sample of 258 new students from the Faculty of Social and Human Sciences at the University of Beira – Portugal, we use structural equation model (SEM) to test our hypotheses. From the structural model, the outcomes reveal that students’ cognitive and psychological factors influence their entrepreneurial intention, but no statistically significant direct effects of these factors were found on academic hazing. Another conclusion is that the entrepreneurial intention has a positive influence on students’ academic hazing and there is an indirect effect of psychological factors on this relation. In this study, a new and innovative construct is inserted in the model of entrepreneurial intention: “Academic Hazing”. Academic hazing is characterised as a ritual of initiation for new students at universities.
Après-ski: The spread of coronavirus from Ischgl through Germany
Authors: Felbermayr Gabriel , Hinz Julian , Chowdhry Sonali 
Published: June 2021

Abstract
The Austrian ski resort of Ischgl is commonly claimed to be ground zero for the diffusion of the SARS-CoV-2 virus in the first wave of infections experienced by Germany. Drawing on data for 401 German counties, we find that conditional on geographical latitude and testing behavior by health authorities, road distance to Ischgl is indeed an important predictor of infection cases, but – in line with expectations – not of fatality rates. Were all German counties located as far from Ischgl as the most distant county of Vorpommern-Rügen, Germany would have seen about 45 % fewer COVID-19 cases. A simple diffusion model predicts that the absolute value of the distance-to-Ischgl elasticity should fall over time when inter- and intra-county mobility are unrestricted. We test this hypothesis and conclude that the German lockdown measures have halted the spread of the virus.
Effect of basicity on the reduction swelling properties of iron ore briquettes

Published: June 2021

Abstract
The influence mechanism of basicity on the reduction swelling index (RSI) of iron ore briquettes was investigated using the SEM analysis and Factsage 7.3 thermodynamic calculations based on the addition of pure CaO to Bayan Obo iron concentrate. The results revealed that the solid solution of Ca2+ in the FeO lattice increased with the basicity of the briquettes, whereas the diffusion channels of Fe2+ ions increased during the reduction process from FeO to Fe and resulted in the formation of a great number of slender and anisotropic iron whiskers, which consequently increased the RSI. Furthermore, the melting point of the slag phase decreased as the CaO content increased; this reduced its ability to resist the reduction swelling of iron oxides. When the basicity was increased from 0.3 to 0.8, the RSI reached a maximum of 69.85%. However, due to the saturated solid solution of Ca2+ in FeO lattice, as the basicity further increased from 0.8 to 1.2, excess CaO melting into the slag phase promoted the precipitation of spinel minerals with high melting points and difficult reduction properties. Thus, the diffusion of Fe2+ and the growth of the iron whiskers were hindered, and the RSI was reduced.
Translating the principles of good governance: in search ofaccountabilityin Spanish and German
Authors: Breeze Ruth 
Published: June 2021

AbstractGood governance is a key factor in underpinning the integrity and efficiency of an institution, whether it is a private company or a national or international organisation. The core principles of good governance are now often defined asfairness,accountability,responsibilityandtransparency. Although these terms are familiar to all those involved in corporate social responsibility/sustainability and business ethics, and are frequently discussed in the European Parliament and European directives, they often pose a challenge to the translator, since obvious equivalents for all of them do not exist in all EU languages. In this paper, I take the example ofaccountability, and examine the way that it is represented in both Spanish and German in the EUROPARL7 parallel corpus of European Parliament Proceedings, available in the Sketch Engine corpus platform.Accountabilityin English can be defined as an assurance that individuals or organizations will be evaluated on their performance or behaviour related to something for which they are responsible, or more simply, as being responsible for explaining what you do and able to give a satisfactory account of it to those whom your actions affect. The English termaccountabilitythus differs fromresponsibilityandtransparency, although it overlaps with both. However, not all languages allow us to distinguish easily between the concepts they designate. In fact, the majority of Spanish translations ofaccountabilityfound in EUROPARL7 simply useresponsabilidad, while others make reference torendir cuentasorrendición de cuentas, and a few actually usetransparencia. In German, the picture is less confused, with the closer termRechenschaftspflichtemployed as the usual translation, but an abundance of alternatives such asVerantwortlichkeitandAuskunftspflichtalso appear. In my conclusions, I discuss the rationale that may underlie the different choices, point to problems that might arise from poor translations, and suggest reasons we should strive to maintain clear definitions of these key concepts.
Distributions of As, Pb, Sn and Zn as minor elements between iron silicate slag and copper in equilibrium with tridymite in the Cu–Fe–O–Si system

Published: June 2021

Abstract
The distributions of arsenic, lead, tin and zinc between iron silicate slag and copper in equilibrium with tridymite in the Cu–Fe–O–Si system have been experimentally determined at selected oxygen partial pressures (P(O2)) at temperatures of 1 523 K and 1 573 K. The experimental technique involved high temperature equilibration in a sealed silica ampoule to minimize the vaporization of minor elements, rapid quenching of the condensed phases, and the direct composition measurements of the condensed phases using microanalysis techniques. The effective P(O2)s of the samples were determined based on the measured Cu2O concentrations in slag. The new experimental data resolve discrepancies found in previous studies and have been used in the development of a new thermodynamic database of the Cu–Fe–O–Si system containing minor elements.

Authors: Amin Huma , Ahmed Suhaib 
Published: June 2021

Abstract

Background
Depending on breakpoints of rearrangement different types of BCR–ABL fusion protein can be generated in patients of chronic myeloid leukemia (CML). The aim of this study is to observe frequencies of major transcripts in CML patients by reverse transcriptase polymerase chain reaction (RT-PCR) and their hematological features at the time of presentation.

Materials and methods
This cross sectional study was performed at Molecular Lab of Riphah International University, Islamabad from January to June 2019. Consecutive peripheral blood samples of 70 newly diagnosed CML patients in chronic phase were analyzed by RT-PCR to detect different BCR–ABL transcripts. Routine blood cell counts were assessed by an automated hematology analyzer.

Results
All samples expressed typical BCR–ABL rearrangement. Expression of either e14a2 or e13a2 transcript was detected in 38 (54%) and 30 (43%) patients, respectively. Coexpression of e13a2 + e14a2 was found in 2 (3%) patients. The mean total leukocyte count was higher in group expressing e13a2 (P = 0.01). Higher mean platelet count was noted in patients with e14a2 transcript, but this difference was statistically insignificant (P = 0.1). The association of male gender was observed with the group exhibiting e14a2 (P = 0.01). There was no statistically significant association between transcript type and different ranges of age, hemoglobin levels, and platelet and total leukocyte counts (P > 0.05).

Conclusion
e14a2 transcript was most common transcript in CML patients. Patients exhibiting e13a2 subgroup presented with significantly higher mean white blood cell count at the time of presentation. Significantly higher proportion of male patients was found to express e14a2 transcript over e13a2.
Characterization of the UV-Visible absorption spectra of manganese(III) porphyrins with time-dependent density functional theory calculations

Published: June 2021

Abstract
Mn(III) porphyrins display a unique UV–Vis spectrum: compared to the free-base and other metalloporphyrins, a strong red shift of the Soret-band and several extra bands can be observed in their spectra. To understand this behavior, we have recorded the UV–Vis spectra of differently substituted water-soluble Mn(III) porphyrins and conducted extensive theoretical investigations using time-dependent density functional theory. The calculated optical transitions, using the O3LYP functional, agree well with the measured absorption bands. According to the spectral interpretation, the Soret-band involves a mixture of L–L and ligand-to-metal charge transfer excitations, while the Q-bands and the higher-energy bands in the UV region correspond to pure LMCT as well as to ligand to metal-ligand mixed orbital excitations. The impact of the explicit and implicit water solvent on the spectral features is also discussed.

Neue Potenziale für die Schleifbearbeitung von Superlegierungen
Authors: Hartig Jörg , Kirsch Benjamin , Aurich Jan C. 
Published: June 2021

Abstract
Nickel-Basis-Legierungen sind aufgrund ihrer hervorragenden mechanischen, thermischen und chemischen Eigenschaften schwer zerspanbar. Die geringe Wärmeleitfähigkeit und die hohe Reibungswärme bei der Schleifbearbeitung führen zu einer unzureichenden Wärmeabfuhr aus der Kontaktzone. Die Folge sind Randzonenschädigungen und ein erhöhter Werkzeugverschleiß. Durch die Anwendung von PVD-Beschichtungen sollen Reibungsvorgänge und chemische Wechselwirkungen in der Kontaktzone reduziert und die Kornhaltekraft verbessert werden.

Riesgo de sesgo de publicación en intervenciones terapéuticas para el COVID-19
Authors: Hasdeu Santiago , Tortosa Fernando 
Published: June 2021

Las revisiones sistemáticas y meta-análisis son diseños de investigación secundaria que constituyen una referencia para guiar la toma de decisiones. Ante la pandemia, un gran número de investigaciones se publican a un ritmo acelerado, por lo que diversas organizaciones han propuesto mantenerlas actualizadas a través de “revisiones vivas”. Aun siendo desarrollados con gran rigor metodológico, el sesgo de publicación puede representar una amenaza a su validez.
Se describen las características de los sesgos de publicación, las vías regulatorias para evitarlo y herramientas estadísticas para sospecharlo.
Se define sesgo de publicación como el hecho de ocultar o retrasar la publicación y/o retener datos surgidos de los estudios de investigación. Hasta la mitad de los ensayos controlados que se realizan permanecen sin publicarse, a causa de diversos intereses. Un ejemplo reciente e impactante fue el acontecido con oseltamivir durante la pandemia H1N1. El ocultamiento y la demora en publicar resultados de estudios financiados por la industria llevó a comprar un medicamento que, luego se supo, no tenía efectos beneficiosos relevantes.
Diversas iniciativas proponen regular la publicación y registro de ensayos clínicos, para reducir este sesgo, y algunas técnicas estadísticas permiten sospecharlo. Se ejemplifica mediante un análisis estadístico de valoración de sesgo de publicación en tres intervenciones terapéuticas relacionadas con COVID-19: corticoides, ivermectina y tocilizumab.
ONLAY VERSUS SUBLAY REPAIR AFTER INCISIONAL HERNIA: WHICH TECHNIQUE TO PREFER?
Authors: Rashaan Mezjda 
Published: June 2021

Background Incisional hernia (IH) is one of the most common complications worldwide after abdominal surgery. For repair of IH, a wide spectrum of surgical techniques is advocated. However, there is no consensus on the ideal technique for mesh location and it remains controversial. Objectives This clinical study aimed to compare the postoperative results of onlay mesh repair with sublay (retro-muscular) mesh repair. Methods This retrospective study was conducted in the surgical department of Sulaimani Teaching hospital from January 2010 to February 2014. Follow up period was for 2 years conducted via telephone or at outpatient clinics. All patients underwent preoperative evaluation and postoperative follow-up with regards to postoperative pain, wound infection, seroma, recurrence rates, and hospital stay. Results A total of 186 patients underwent open mesh repair for incisional hernia of whom 96 cases were operated on by onlay technique and 90 cases by sublay mesh repair. Patients who underwent onlay repair had statistically significant more post-operative complications compared to the sublay group 33 patients (34.4%) vs. 13 patients (14.4%), p< 0.001. In the onlay group, the incidence of recurrence was 13 (13.5%) compared with 3 (3.3%, p= 0.01) in the sublay group. 3 patients (3.3%) in the sublay group had wound infection compared with 10 patients (10.4%, p=0.05) in the onlay group. Patients in the onlay group had statistically significant more moderate pain (VAS 4-6) during hospital admission compared with the sublay group (82 (85.4%) vs. 62 (68.9%), p=0.01). However, patients in the sublay group had statistically more severe pain (VAS 7-10) during hospital admission compared to the onlay (28 (31.1%) vs. 14 (14.6%), p=0.01). Conclusion Sublay mesh repair is to be preferred to the onlay mesh repair technique because of the statistically significant less postoperative complications such as recurrence and wound infection.

Quality control technic is an important method of designing a strategic plan for many productive industries. The Shewhart control chart is that it uses only the information observation. Cumulative sum (CUSUM) and Exponentially weighted moving average (EWMA) two very effective alternatives to the Shewhart control chart may be used when small process shifts are of interest. This paper discusses data on failure time of five cement mills in Sulaimani Mass cement factories, used, the reliability methods for analysis the failure time. The quality of the products manufactured in this factory has been estimated according to a quality control process through the use of specific control chart one of the chart Exponentially Weighted Moving Average (EWMA) chart. Whereas reliability concerns functioning under specified time. So, it can be said that the reliability is a relation between production with expected period time in quality. This study investigates the implementation of reliability and quality control. The findings indicate that factors that affecting the function of mills which will increase the failure rate of mills and lower their life span, through which quality of products will be affected.

Published: June 2021

In 2020, the activities of the oncological service of the Russian Federation were complicated by the development of the SARS-CoV‑2 respiratory syndrome, which had a pronounced effect on the health of patients with malignant neoplasms (MN) and contributed to the reorientation of employees of oncological services to ensure a special regime. The vertical line of continuity in the diagnosis and treatment of patients with malignant neoplasms was violated, the timing of treatment was violated. Aspects of the organization of the oncological service of the Magadan region (MagO) in the context of the SARS-CoV‑2 pandemic have been studied.Purpose of the study. To assess the features cancer detection among the citizens of the Magistral District in 2019-2020.Materials and methods. The available sources of information (documents of the Ministry of Health of the MagO), databases of the oncological dispensary (IODE), based on information from the state reporting forms – ff. 7 and 30, as well as from Internet resources. Results. MagO region, leading in the rate of morbidity and mortality from malignant neoplasms in the Far Eastern Federal District: incidence of malignant neoplasms for 2009-2019 increased by 23 %. In 2020, the indicator of malignant neoplasm (from 35 % to 25.4 %) decreased in the MAO, and the proportion of patients with malignant neoplasms in localized (III) stages was 50 %. In August 2020, the CAPC began to work, for 5 months. Cancer was detected in 35 people (7.6 %), including in the early (I-II) stages in 18 people, which did not significantly affect the rate of early detection of cancer. Physical examinations revealed 107 cases of malignant neoplasm (a decrease of 27.4 % compared to 2019). In 2019-2020 In the MAO, cancer screening was carried out for a number of nosoologies: as a result, the proportion of patients with lung cancer (MagO – 36 %, RF – 29.4 %) and cervix (MagO – 82 %, RF – 66 %) exceeded the national average.Conclusion. To increase the detection of malignant neoplasms, it’s necessary to provide examination rooms in the districts of the MagO; drawing up a "map of contamination of the territory"; assessment of the conditions of human production activity and population density; introduction of the standard of examination of patients with cancer; increasing the alertness and qualifications of primary outpatient medical personnel.
Toward False Event Detection and Quarry Blast versus Earthquake Discrimination in an Operational Setting Using Semiautomated Machine Learning
Authors: Renouard Alexandra , Maggi Alessia , Grunberg Marc , Doubre Cécile , Hibert Clément 
Published: June 2021

AbstractSmall-magnitude earthquakes shed light on the spatial and magnitude distribution of natural seismicity, as well as its rate and occurrence, especially in stable continental regions where natural seismicity remains difficult to explain under slow strain-rate conditions. However, capturing them in catalogs is strongly hindered by signal-to-noise ratio issues, resulting in high rates of false and man-made events also being detected. Accurate and robust discrimination of these events is critical for optimally detecting small earthquakes. This requires uncovering recurrent salient features that can rapidly distinguish first false events from real events, then earthquakes from man-made events (mainly quarry blasts), despite high signal variability and noise content. In this study, we combined the complementary strengths of human and interpretable rule-based machine-learning algorithms for solving this classification problem. We used human expert knowledge to co-create two reliable machine-learning classifiers through human-assisted selection of classification features and review of events with uncertain classifier predictions. The two classifiers are integrated into the SeisComP3 operational monitoring system. The first one discards false events from the set of events obtained with a low short-term average/long-term average threshold; the second one labels the remaining events as either earthquakes or quarry blasts. When run in an operational setting, the first classifier correctly detected more than 99% of false events and just over 93% of earthquakes; the second classifier correctly labeled 95% of quarry blasts and 96% of earthquakes. After a manual review of the second classifier low-confidence outputs, the final catalog contained fewer than 2% of misclassified events. These results confirm that machine learning strengthens the quality of earthquake catalogs and that the performance of machine-learning classifiers can be improved through human expertise. Our study promotes a broader implication of hybrid intelligence monitoring within seismological observatories.
