The article dwells on the accuracy of the unified approach of the survival function method (SFM), which is used to determine the probability of failure-free operation (PFFO) of the launch vehicles mechanical systems at the design stage. For the survival function in the form of a safety factor, which is universal, depending on the order of its expansion in the Taylor series, as well as the order of used numerical characteristics of the input parameters (factors determine the main errors of the unified approach), the accuracy of obtaining the numerical characteristics of the state variable and, ultimately, PFFO is analyzed. The case of normal distribution of bearing capacity and stress was considered, as well as the case when the indicated random variables followed the Gram-Charlier distributions. An expression is proposed for the density of the safety factor distribution in the case when the bearing capacity and stress are described by the Gram-Charlier distributions.
The calculations have confirmed that the linearization method (first-order approximation) for nonlinear survival functions and non-normal distributions of its arguments can lead to a significant deviation of the reliability factor from the exact value. The orders of expansion of the survival function in the Taylor series and the numerical characteristics of its arguments are determined, which are recommended for practical use for PFFO determination in case of non-linear survival functions, as well as the case when the input parameters have non-normal distributions. Separately, the case of limiting the order of the used numerical characteristics of the survival functions arguments is considered, and recommendations are made to improve the accuracy of the SFM unified approach. For non-normal distributions of bearing capacity and stress, a very slow convergence of the numerical characteristics of the third and fourth orders to exact values was obtained with increasing orders of expansion of the survival functions in the Taylor series and used numerical characteristics of the input parameters. The Gram-Charlier distribution, used to describe the state variable in nonlinear models, allows obtaining a PFFO value closer to the exact one than the normal distribution.

Authors: Rodrigues Paola da Cruz , Tomelin Jr. Nelson 
Published: May 2022

Este artigo é resultado das discussões do Programa Institucional de Bolsas de Iniciação Científica (PIBIC) intitulado “Crime e Criminalização na Imprensa: Movimentos Sociais e vida Urbana na cidade de Manaus (1985-1989)”, possibilitado pela reflexão sobre a imprensa periódica escrita como força ativa na representação da criminalidade e na criminalização de movimentos sociais e outros fazeres urbanos na cidade de Manaus, entre os anos de 1985 e 1989. Tendo como foco a produção de jornal de grande circulação, buscou-se compreender os interesses e as disputas regionais que encadeiam, naquele momento, também valores em torno da ideologia do progresso. A esfera política de atrelamento desses diferentes conteúdos se dá por perspectivas culturais amplas, contribuindo a matéria, de forte apelo midiático, para a articulação de interesses comerciais e empresariais, sendo igualmente alvo da resistência de trabalhadores e trabalhadoras organizados de dentro de seus modos próprios de vida na cidade. O recorte temporal analisado marca o fim da ditadura civil-militar de 1964 e seu após, passando pela promulgação da Constituição Federal do Brasil de 1988 com a consolidação, nesse texto, de importantes políticas sobre o direito à cidade, as quais avançaram o marco civilizatório no país. Tais debates também estiveram presentes na imprensa do período, inclusive com a participação, nessas páginas, de sujeitos históricos diversos que então lutaram por democracia.

Published: May 2022

AbstractThe operation of combined mass spectrometry and electrochemistry setups has recently become a powerful approach for the in situ analysis of gas evolution in batteries. It allows for real-time insights and mechanistic understanding into different processes, including battery formation, operation, degradation, and behavior under stress conditions. Important information is gained on the safety and stability window as well as on the effect of protecting strategies, such as surface coatings, dopings, and electrolyte additives. This review primarily aims at summarizing recent findings on the gassing behavior in different kinds of liquid- and solid-electrolyte-based batteries, with emphasis placed on novel cathode-active materials and isotope labeling experiments, to highlight the relevance of in situ gas analysis for elucidation of reaction mechanisms. Various instrumental and experimental approaches are presented to encourage and inspire both novices and experienced scientists in the field.

Sistem pengisian token listrik pada meter listrik prabayar sampai saat ini masih dilakukan secara manual, yaitu pengguna menginputkan nomor token secara langsung di perangkat meter listrik menggunakan keypad. Permasalahan terjadi saat pengguna sedang berada di luar rumah. Pengguna tidak dapat memasukkan token listrik pada meter listrik di rumah dari jarak jauh. Penelitian ini bertujuan untuk merancang sistem pengisian token listrik prabayar secara jarak jauh menggunakan teknologi Internet of Things. Model sistem yang dirancang yaitu dengan memasukkan token pada aplikasi android yang akan dikirimkan ke sistem berbasis Arduino melalui server cloud (Firebase). Perangkat D1 mini board digunakan untuk akses ke jaringan internet melalui Wi-Fi. Sensor arus digunakan untuk mengukur besarnya energi listrik yang terpakai dan akan mengurangi jumlah token pulsa listrik deposit yang ada di sistem secara real time. Hasil pengujian sistem sistem menunjukkan bahwa akurasi sensor arus sebesar 97,52%, laju penurunan tegangan pada modul catu daya cadangan sebesar 0,07 Volt/jam, serta kecepatan transfer data sebesar 21,7 kbps. Hal ini menunjukkan bahwa sistem yang dirancang dapat bekerja dengan baik untuk fungsi pengisian token listrik secara jarak jauh. The electricity token filling system for prepaid electricity meters is still done manually, where the user inputs the token number directly on the electricity meter device using the keypad. The problem occurs when the user is out of the house. The user cannot enter the electricity token on the electricity meter at home remotely. This study aims to design a prepaid electricity token charging system remotely using Internet of Things technology. The system model designed is by entering a token in the android application which will be sent to an Arduino-based system via a cloud server (Firebase). The D1 mini board device is used for access to the internet network via Wi-Fi. The current sensor is used to measure the amount of electrical energy used and will reduce the number of deposit tokens in the system in real time. The system test results show that the current sensor accuracy is 97.52%, the rate of voltage drop on the backup power supply module is 0.07 Volts/hour, and the data transfer rate is 21.7 kbps. This shows that the system designed can work well for the function of charging electricity tokens remotely.
A Composite End Point of Graft Status and eGFR at 1 Year to Improve the Scientific Registry of Transplant Recipients’ Five-Tier Rating System
Authors: Wang Kaicheng , Deng Yanhong , Stewart Darren , Formica Richard N. 
Published: May 2022

Significance Statement
Quantifying meaningful differences in competency of kidney transplant programs based on 1-year survival rates is challenging because of relatively few allograft failure events per program and increasing homogeneity in program performance. In this study, the researchers found that compared with the traditional end point of graft status (allograft failure at 1-year post-transplant), a composite end point that incorporates a measure of allograft function—the recipients’ eGFR <30 ml/min per 1.73 m2 or graft failure at 1 year—performed better in differentiating between transplant programs with respect to long-term deceased donor graft outcomes. Incorporating granular measures of allograft function into performance metrics instead of solely using a binary (functioning/failed) indicator has the potential to improve patient care by prioritizing allograft function as a measure of program quality.

Background
Performance of kidney transplant programs in the United States is monitored and publicly reported by the Scientific Registry of Transplant Recipients (SRTR). With relatively few allograft failure events per program and increasing homogeneity in program performance, quantifying meaningful differences in program competency based only on 1-year survival rates is challenging.

Methods
We explored whether the traditional end point of allograft failure at 1 year can be improved by incorporating a measure of allograft function (i.e., eGFR) into a composite end point. We divided SRTR data from 2008 through 2018 into a training and validation set and recreated SRTR tiers, using the traditional and composite end points. The conditional 5-year deceased donor allograft survival and 5-year eGFR were then assessed using each approach.

Results
Compared with the traditional end point, the composite end point of graft failure or eGFR <30 ml/min per 1.73 m2 at 1-year post-transplant performed better in stratifying transplant programs based on long-term deceased donor graft survival. For tiers 1 through 5 respectively, the 5-year conditional graft survival was 72.9%, 74.8%, 75.4%, 77.0%, and 79.7% using the traditional end point and 71.1%, 74.4%, 76.9%, 77.0%, and 78.4% with the composite end point. Additionally, with the five-tier system derived from the composite end point, programs in tier 3, tier 4, and tier 5 had significantly higher mean eGFRs at 5 years compared with programs in tier 1. There were no significant eGFR differences among tiers derived from the traditional end point alone.

Conclusions
This proof-of-concept study suggests that a composite end point incorporating allograft function may improve the post-transplant component of the five-tier system by better differentiating between transplant programs with respect to long-term graft outcomes.
Hispania ante portas: cambio y continuidad en el posicionamiento de la República Federal de Alemania frente a la adhesión de España a las Comunidades Europeas (1977-1985)
Authors: Sáenz Rotko José Manuel 
Published: May 2022

En el largo y tortuoso camino de las negociaciones para la adhesión de España a las Comunidades Europeas, Alemania desempeñó un papel decisivo como firme defensor de las aspiraciones españolas y como persistente facilitador de acuerdos políticos en el seno de los países miembros, que posibilitó finalmente la entrada del país ibérico en el club europeo. El presente artículo tiene como objeto, por un lado, desgranar las razones de la posición y actitud alemanas, arraigadas en la definición del proyecto de integración europea como elemento fundamental en relación a su seguridad nacional. Por otro, pretende analizar, con recurso a cuantiosa documentación inédita, la evolución de la política de Bonn respecto de la ronda de ampliación hacia el sur a lo largo de los ocho años del proceso. Sobre esta base se destacarán los elementos de cambio y continuidad, que venían condicionados no solo por la evolución de la Transición en España, sino también por el liderazgo político en la República Federal y por supuesto por las dinámicas e intereses de los Estados miembros en el seno de las Comunidades Europeas. Se detallará, asimismo, el activismo que la Alemania de Kohl asumió a partir de 1983 para superar los múltiples escollos que amenazaban con retrasar significativamente la culminación exitosa de las negociaciones e incluso hacer descarrilar el proyecto europeísta español.

El arrastre de acreedores en la Directiva UE 2019/1023 sobre marcos de reestructuración preventiva y su transposición al Derecho preconcursal español
Authors: Martínez Muñoz Miguel 
Published: May 2022

El arrastre de acreedores constituye un mecanismo muy eficaz para alcanzar una reestructuración forzosa de la deuda y sortear así el concurso de acreedores. La Directiva UE 2019/1023 contempla, además del tradicional arrastre intra-clases, el arrastre entre clases a semejanza de otros ordenamientos de corte anglosajón, lo que plantea ciertas novedades para la práctica española. Por ello, se hace necesario realizar un estudio de la institución y analizar los distintos elementos que componen el arrastre para observar cómo se han plasmado las directrices europeas en el Proyecto de Ley de Reforma de la Ley Concursal con el objetivo de detectar ineficiencias o, incluso, posibles problemas.

Published: May 2022

PurposeThis article provided a comprehensive overview of the available peer-reviewed and grey literature on the current status of historically Black colleges and universities (HBCUs) and small African American-owned technology firms participation in the federal assistive technology research and development (AT-R&D) enterprise.Method Authors completed a historical review of the existing literature on HBCUs' participation in STEM academic pathways to AT-R&D; the contextual framework for HBCUs federal R&D barriers; STEM pathways to small African American Technology Entrepreneurship; and small African American-owned technology firms AT-R&D participation barriers.ResultsOverall, the review illuminated participation barriers experienced; exacerbated in part by narrow STEM pathways designed to help African American students successfully matriculate in related disciplines, institutional systematic barriers, a lack of funding priorities within federal research agencies, and the oversight of African American entrepreneurs in AT.ConclusionsThe authors presented recommendations that might be useful for developing proactive academic pipelines to AT-R&D. The literature review is among the first to examine HBCUs' participation in STEM pathways to federally-funded AT-R&D.

Published: May 2022

PURPOSEThis study explored the acceptability and practicality of implementing a Direct Skills Teaching (DST) approach to increase job interview preparation for individuals who were receiving state vocational rehabilitation (VR) services in four states.METHODCounselors-in-training facilitated a four-session curriculum teaching “Presenting Qualifications” during job interviews to 137 individuals in 25 groups settings. Pre- and post-group 10-item questionnaires of skill acquisition, and a post-group satisfaction survey with open-ended questions were administered. Descriptive statistics and a nonparametric Wilcoxon signed rank test were used for data analyses.RESULTSAll 10 items of the pre- and post-group questionnaire comparisons yielded significant improvement in the skill of “Presenting Qualifications” after group intervention. The satisfaction survey also indicated the positive experiences of participants.CONCLUSIONSThe findings demonstrate the feasibility of a structured DST curriculum in teaching job interview skills to people with disabilities (including transition age youth) served by state VR agencies.

Published: May 2022

PURPOSETo explore Louisiana Vocational Rehabilitation Counselors’ (VRCs’) perceptions and experiences in utilizing career theories suggested by Easter and Gaertner (2009) when providing vocational guidance and career counseling to clients with a criminal record. Results from this research will provide insight to current and prospective VRCs in their practice and heighten educators’ and supervisors’ awareness of VRCs’ experience using career theories.METHODSSix Louisiana VRCs with at least two years of experience working with clients who had a criminal background were interviewed twice using heuristic inquiry. This qualitative method relies on researchers’ ability to discover and interpret their own experiences while exploring others’ experiences. The data were analyzed by performing both opened-coding and axial-coding.RESULTSFour major themes were revealed from this qualitative study: (1) expectations, (2) autonomy, (3) counselor development, and (4) fidelity to career theories. Upon further analysis, the emergent theory suggested incongruence of theory and practice amongst participating VRCs. Findings suggest VRCs working with clients with criminal backgrounds do not feel their academic training has prepared them to use career theories with this population effectively.CONCLUSIONWhen the participants apply the career theories suggested by Easter and Gaertner to clients with a criminal record, they perceive them to be ineffective. Therefore, this study serves as a baseline for additional research and suggests additional training may be necessary for VRCs who work with clients with a criminal background.
Educação especial e políticas educacionais
Authors: Matos Neide da Silveira Duarte de , Tureck Lucia Terezinha Zanato 
Published: May 2022

O artigo busca expor alguns marcos históricos presentes na legislação brasileira que permitam compreender as concepções de aprendizagem e desenvolvimento humano de pessoas com deficiência, em especial nas políticas educacionais para a Educação Especial. De natureza bibliográfica e documental, analisa documentos de organismos nacionais e internacionais que orientaram essas políticas, considerando que revelam em cada momento histórico uma interpretação própria de desenvolvimento humano e da perspectiva de educação ofertada. Cada documento e/ou diretriz curricular remete a dado entendimento sobre a construção social da deficiência associada às formas de educação escolar necessárias. Constata-se disputas entre concepções sobre aprendizagem e desenvolvimento humano nas políticas de Educação Especial no Brasil, que tomaram forma na organização da modalidade, suas definições de atendimento e formação de professores. Nos limites dessa análise, levanta-se aspectos que contribuam para apreender as configurações que tais disputas assumem na política de Educação Especial, face às orientações internacionais que consideram o acesso à educação escolar como meio de promoção de justiça e igualdade social e, também, a uma educação para todos com participação efetiva das pessoas com deficiência e as possibilidades de sua instrumentalização.
