Parents Matter: Associations Between Parent Connectedness and Sexual Health Indicators Among Transgender and Gender‐Diverse Adolescents
Authors: Brown Camille , Eisenberg Marla E. , McMorris Barbara J. , Sieving Renee E. 
Published: January 2021

CONTEXTTransgender and gender‐diverse youth experience significant health disparities across numerous domains of health, including sexual health. Among general populations, parent connectedness has been strongly associated with youth sexual health.METHODSThe relationships between parent connectedness and sexual health indicators were investigated among 2,168 transgender and gender‐diverse youth who participated in the 2016 Minnesota Student Survey, a statewide population‐based survey of ninth‐ and 11th‐grade students. Multivariate logistic regression models, stratified by sex assigned at birth, tested associations between parent connectedness—youth's perceptions of parent caring and parent–youth communication—and eight sexual health indicators: ever having had sex, having multiple sexual partners in the past year, pregnancy involvement, substance use at last sex, partner communication about STI prevention, partner communication about pregnancy prevention, condom use at last sex and pregnancy prevention methods at last sex.RESULTSThe level of parent connectedness was inversely associated with ever having had sex, regardless of sex assigned at birth (odds ratios, 0.6–0.8). Although level of connectedness was inversely associated with having multiple sexual partners in the past year and pregnancy involvement among transgender and gender‐diverse youth assigned male at birth (0.6–0.7), these relationships were nonsignificant among transgender and gender‐diverse youth assigned female at birth. Further differences in associations between parent connectedness and four sexual risk–reduction behaviors were found between youth assigned male at birth and those assigned female.CONCLUSIONSAs with other populations, parent connectedness promotes sexual health among transgender and gender‐diverse youth and may provide a point of intervention.

Published: January 2021

Abstract
In this paper, the evolution of space debris for spacecraft in the Sun-Synchronous orbit has been investigated. The impact motion, the evolution of debris from the Sun-Synchronous orbit, as well as the evolution of debris clouds from the quasi-Sun-Synchronous orbit have been studied. The formulas to calculate the evolution of debris objects have been derived. The relative relationships of the velocity error and the rate of change of the right ascension of the ascending node have been presented. Three debris objects with different orbital parameters have been selected to investigate the evolution of space debris caused by the Sun-Synchronous orbit. The debris objects may stay in quasi-Sun-Synchronous orbits or non-Sun-Synchronous orbits, which depend on the initial velocity errors of these objects.
Mathematics Teaching in Slovakia during COVID-19 Quarantine Season in Spring of 2020
Authors: Csachová Lucia , Jurečková Mária 
Published: January 2021

AbstractIn many countries, the attendance form of education was interrupted during quarantine in the spring of 2020 and replaced by some form of distance education. The COVID-19 pandemic has thus tested the preparedness of schools, teachers and educational systems in general to provide various forms of distance education. This paper briefly describes the situation in mathematics teaching in lower and upper secondary schools during the spring quarantine in Slovakia. We focus on the initial reactions and early experience of mathematics teachers. They have used different applications, software and methods in teaching mathematics during this time. Our goal is not to evaluate whether the teachers managed it or not, but what and how they had to do so that the educational process in mathematics would not be interrupted.
The Career Model of 21st Century Adopted By Higher Education Graduates
Authors: Negoiţă Gabriela 
Published: January 2021

Abstract
The present paper has identified two career models, the Protean Career and the Boundaryless Career, that can be considered to accommodate higher education graduates’ personal and professional needs, as well as the flexibility and adaptability requirements of the current labor market. The research used the data from a tracer study applied online to the graduates of the West University of Timisoara, with a response rate of 25% (which falls within the response rate for similar studies at the European level).
There has been an increased dynamic of the number of jobs compared to the short period since they have been active on the labor market, especially among male graduates. At the level of individual factors that can influence career success, the importance given to both objective and subjective values is observed. The results have shown that for graduates, income, job security, the possibility of promotion, the use of knowledge, but especially leisure time, are equal priorities, with consistent values in time for both stages of the study. Moreover, there has been a significant negative association between the variables of leisure time and job satisfaction (r (522) = -.17, p <.001). Given the mode of action, the high dynamics of jobs, which reflect the much-needed flexibility in the dynamic context of the labor market, and the values that have guided job search, often working and studying at the same time, the pattern of employment career that most accurately describes the career profile of graduates seems to be that of the Protean career (the path with a heart), also called the career of the 21st century.
Cultural Heritage and Urban Landscape in a Future European Cultural Capital – Challenges and Trends
Authors: Oniţiu Atalia , Balaci Mariana 
Published: January 2021

Abstract
European countries interest for archaeological heritage, as part of the cultural landscape, was firstly expressed at the London Convention (1969), whose content was later revised by La Valetta Convention (1992). Romania joined this Convention in 2000, thus assuming the mission to protect and preserve the archaeological heritage, facing with massive economic development and urban expansion. Although we speak of a consecrated historical center, in Timisoara’s urban landscape preventive archaeology has become a reality only from 2004, when first researches were conducted. During the last few years, local infrastructure development has determined an extension of archaeological investigations over the historical area of the city, with major influences especially over public transportation (most of the times hampered, sometimes deviated, even blocked in the specific area, during archaeological research). Our approach focuses on multiple facets and implications of preventive archaeology over Timisoara’s urban landscape, from immediate, obvious issues (such as population’s satisfaction regarding archaeological investigations, their consequences (over access in the area, safety or transportation)), to long-term results (over local tourism, urban development or locals’ education for protecting and promoting cultural heritage).
Simply connected translating solitons contained in slabs
Authors: Chini Francesco 
Published: January 2021

AbstractIn this work we show that 2-dimensional, simply connected, translating solitons of the mean curvature flow embedded in a slab of ℝ3 with entropy strictly less than 3 must be mean convex and thus, thanks to a result by Spruck and Xiao are convex. Recently, such 2-dimensional convex translating solitons have been completely classified, up to an ambient isometry, as vertical planes, (tilted) grim reaper cylinders, Δ-wings and bowl translater. These are all contained in a slab, except for the rotationally symmetric bowl translater. New examples by Ho man, Martín and White show that the bound on the entropy is necessary.

AbstractCytotoxic necrotizing factors (CNFs) are bacterial single‐chain exotoxins that modulate cytokinetic/oncogenic and inflammatory processes through activation of host cell Rho GTPases. To achieve this, they are secreted, bind surface receptors to induce endocytosis and translocate a catalytic unit into the cytosol to intoxicate host cells. A three‐dimensional structure that provides insight into the underlying mechanisms is still lacking. Here, we determined the crystal structure of full‐length Yersinia pseudotuberculosis CNFY. CNFY consists of five domains (D1–D5), and by integrating structural and functional data, we demonstrate that D1–3 act as export and translocation module for the catalytic unit (D4–5) and for a fused β‐lactamase reporter protein. We further found that D4, which possesses structural similarity to ADP‐ribosyl transferases, but had no equivalent catalytic activity, changed its position to interact extensively with D5 in the crystal structure of the free D4–5 fragment. This liberates D5 from a semi‐blocked conformation in full‐length CNFY, leading to higher deamidation activity. Finally, we identify CNF translocation modules in several uncharacterized fusion proteins, which suggests their usability as a broad‐specificity protein delivery tool.
Distributed Acoustic Sensing Using a Large-Volume Airgun Source and Internet Fiber in an Urban Area

AbstractSeismological methods have been widely used to construct subsurface images in urban areas, for both seismological and engineering purposes. However, it remains a challenge to continuously operate a dense array in cities for high-resolution 4D imaging. In this study, we utilized distributed acoustic sensing (DAS) and a 5.2 km long, L-shaped, telecom, fiber-optic cable to record the wavefield from a highly repeatable airgun source located 7–10 km away. No P-wave signal was observed, but the S-wave signal emerged clearly on the shot-stacked traces, and the arrivals were consistent with collocated geophone traces. Because the signal quality is significantly affected by cable coupling and local noise, three methods can be employed to improve signal-to-noise ratio: (1) stacking contiguous, colinear channels to increase effective gauge length, (2) connecting multiple fibers within a single conduit and stacking collocated channels, and (3) using engineered fiber. In conclusion, the combination of DAS, using internet fiber and an airgun source with proven efficient signal enhancement methods, can provide frequent snapshots of the near surface across an urban area.

Published: January 2021

Abstract
Although Norway has had an open data policy for seismological data for a long time, access to a good portion of the data required the use of nonstandard tools. This changed with the establishment of a dedicated European Integrated Data Archive (EIDA) node that is operated jointly by the UiB (University of Bergen)-NORSAR. This now gives access to 139 stations and currently 12.1 Tb of data. The archive continues to grow with new data from permanent stations that are added in near-real time, the backfilling of archives from permanent networks and providing access to temporary deployments. The software behind the EIDA node is SeisComP, and access to data and metadata is through standard International Federation of Digital Seismograph Networks (FDSN) and EIDA webservices. Quality metrics are computed through the EIDA WFcatalog tools and in addition Modular Utility for STAtistical kNowledge Gathering metrics are computed with Incorporated Research Institutions for Seismology System for Portable Assessment of Quality. The added value from the new UiB-NORSAR EIDA node is that it integrates data from high-quality single and array stations from the Norwegian intraplate region into the common European system.

The possible side effects of transrectal ultrasonography-guided prostate biopsy (TRUS-Bx), which is one of the most common procedure of urology practice, are common but tend to limit themselves. TRUS-Bx may be associated with Lower Urinary System Symptoms (LUTS). We aimed to investigate the effects of TRUS-Bx on LUTS and the factors that decrease or increase these effects and to provide information about the exposure periods of these factors. This study is a prospective observational study involving patients undergoing prostate biopsy between August 1st, 2019 to 2020. Detailed history was obtained and physical examinations were evaluated from all patients. Patients' age, PSA levels, prostate volumes, Body-Mass-Index measurements and use of alpha blocker were recorded. The effects of recorded information of patients with prostate biopsy on LUTS and uroflowmetry parameters were investigated. A total of 143 patients were included in the study after determining the exclusion criteria. A significant correlation was found only between Qmax changes after TRUS-Bx and the use of alpha blockers. All patients, have decreased Qmax flow rate observed at postprocedure 1th day compared to baseline values. During the controls performed in the 4th week, while the decrease in patients using alpha blockers reached a significantly higher value than its baseline value, it could not return to its baseline value in patients who do not use alpha blockers. Prostate biopsy is expected to cause a temporary LUTS. The effects on this LUTS can be corrected with the use of alpha blockers.

Published: January 2021

Feature
The current prospect for the petroleum industry is a future in which the big crew change retires experienced professionals without qualified workers to replace them. A lack of experienced personnel could cost the industry as much as USD 35 billion per year. To some extent, the problem has been alleviated by the rise in the number of petroleum engineering students in recent years.
Blended Learning: Setting the Course for the "Crew Change"
Authors: Benthall Nigel 
Published: January 2021

Feature
What must the E&P industry do to better attract and retain new talent? The answer is to improve the younger generation's professional experience while simultaneously capturing the knowledge base of retiring technical professionals. As one E&P executive recently put it: "In the face of our so-called ‘crew change,’ we must find a way for our young engineers to experience more and our senior engineers to do more." In both cases, technical professionals must increase their day-to-day proficiencies and shorten learning curves when it comes to adopting new technologies and techniques.
The Need for New Recruitment Strategies
Authors: Parmesh Manoj 
Published: January 2021

HR Perspective
Recruitment has become the most challenging human resources (HR) function across all industries today. For a specialized field such as oil and gas, the challenges are enormous. Why is it so difficult to attract new talent? There are three main reasons. First, industrial activity across the world is at an all-time high, which has created more jobs and thus shrunk the availability of personnel. Second, the oil and gas industry has been hurt over the past 20 years because of its cyclicality and public perception. Third, the "baby boomer" generation is approaching retirement and the younger generation is not in sufficient numbers or experienced enough to fill the gap.

Published: January 2021

Abstract
Background: Stress, which can be attributed by household and workplace stressors, is prevalent among nurses. However, this stressors’ attribution may differ between hospital and non-hospital nurses. It is also currently unknown whether there are significant differences in the sociodemographic and occupational characteristics between hospital and non-hospital nurses which may potentially influence the type and magnitude of stressors, and subsequently the stress status. Therefore, this study aims to estimate the prevalence of stress and compare the roles of sociodemograhic characteristics, occupational profiles, and workplace and household stressors in determining the stress status between hospital and non-hospital female nurses in Malaysia.Methods: This cross-sectional study was conducted among randomly-selected 734 female nurses in Malaysia using pencil-and-paper self-reported questionnaires.Results: The majority of participants were ever married (87.0%), having children (76.2%), and work in hospital setting (64.8%). The level of household stressors was generally similar between hospital and non-hospital nurses. However, hospital nurses significantly perceived higher level of workplace stressors. Shift work is significantly associated with higher level of household and workplace stressors among nurses in both groups. The level of stress was significantly higher among hospital nurses. Both household and workplace stressors explained about 40% of stress status in both hospital and non-hospital nurses.Conclusion: Hospital nurses are at higher risk of having stressors and stress as compared to non-hospital nurses, probably due to higher proportion of them involved in shift work. Hospital nurses should be given high priority in mitigating stress among nurses.
