Authors: Marquez Luana Assis , Santos Stéfany Vasconcelos , Dias Sarah Vargas , Oliveira Lara Machado de , Mota Rafaela Colodete , Paulo Marcela Lima Souza
Published: November 2021

Introdução: A gravidez ectópica (GE) é a emergência ginecológica mais comum no mundo, sendo considerada como a implantação do óvulo em qualquer lugar fora do útero, que, na maioria dos casos (98%), ocorre nas tubas uterinas. Cada vez mais é observado o acréscimo dos diagnósticos de GE no mundo, a qual é responsável por 75% dos óbitos nos primeiros meses de gestação. Portanto é imprescindível a análise das razões de chance, ou fatores de risco, para GE, visto que elas são observadas em conjunto por essa gravidez ser caracterizada por causas multifatoriais. Objetivo: Verificar os fatores de risco para o acontecimento de uma gravidez ectópica. Método: Artigo de revisão realizado de setembro a novembro de 2019 na Biblioteca Virtual em Saúde (BVS), utilizando as bases de dados Medical Literature Analysis and Retrieval System Online (MEDLINE) e Literatura Latino-Americana e do Caribe em Ciências da Saúde (Lilacs). Foram selecionados 236 artigos com o uso das expressões de busca “pregnancy, tubal” OR “pregnancy, ectopic” AND “odds ratio”, definidas pelo Medical Subject Headings (MeSH). Consideraram-se como critérios de inclusão e exclusão o idioma inglês, os limites feminino e gravidez, documentos do tipo artigo, com texto disponível completo e publicados nos últimos cinco anos, selecionados pelo assunto principal: gravidez ectópica. Com base nisso, foram excluídos 211 artigos e restaram 25. Após a leitura dos títulos e resumos, foram escolhidos por fim nove artigos, que correspondiam melhor ao objetivo do estudo. Resultados: Pode- se observar que a história de infertilidade e a salpingectomia em gravidezes ectópicas anteriores são os fatores de risco mais significativos para a recorrência de uma GE. A técnica de fertilização in vitro (FIV) tem sido um tratamento comum para a infertilidade, porém surgem complicações como a síndrome da hiperestimulação ovariana, GE e gravidez múltipla. Apesar de ser um tratamento, possui alta taxa de GE, pois a maioria das mulheres que o fazem é infértil. Além disso, há indícios de GE em função do uso de anticoncepcionais, pois uma determinada combinação de hormônios pode inibir a atividade tubária. Ademais, a doença de Crohn pode tornar as mulheres mais suscetíveis a ter perfurações do que as com colite ulcerativa, o que pode contribuir como um fator de risco para a ocorrência de GE. Conclusão: Após a finalização do estudo dos artigos selecionados, certificou-se de que os fatores mais relevantes para a incidência de gravidez ectópica foram o histórico de infertilidade e a salpingectomia. Além disso, na FIV, as condições hormonais, imunológicas e da atividade uterina influenciam diretamente no episódio de GE.

Published: November 2021

The customary puerperal usage of Natron consumption has been identified as one of the risk factors in the cause of high blood pressure in human as well as kidney diseases and abortion in early pregnancies in female. This study was done to determine the effect of Natron and other Natron alternatives on the histology of kidney and liver in male Wistar Albino rats Twenty-five Wistar albino rats of the same sexes (male) weighing 100- 140 kg body weights were used and were divided into five groups. Group 1, 2, 3 and 4 were fed with feed mixed with natron powder, feed mixed with wood ash, feed mixed with sesame ash, feed mixed with palm fruit bunch ash respectively, while group 6 served as a normal control (fed with plain feed). The animals were kept in plastic cages, allowed to acclimatize for two weeks before the commencement of the experiment. They were fed with pelletized growers’ feed (Vital feed) and were allowed access to water. The rats were fed with 25kg of feeds for 12 days to allow them stabilized and recover from stress. Then the rats were fed with the pelletized feed for four weeks to all the groups. The animals were anaesthetized with chloroform vapour after 4 weeks and blood samples were collected through cardiac puncture into labeled tubes for electrolyte analyses. The labeled centrifuge tubes were allowed to stand for 30 minutes to clot and centrifuged at 4000 g for 10mm and the serum obtained was pipette into labeled tubes. The organs were subjected to histology. The liver tissues were embedded in paraffin wax, sectioned at 5μm and stained by hematoxylin and eosin. Proximate analysis showed that natron, palm bunch ash, sesame stem ash, and parkia wood ash had crude protein values of 0.03%, 0.05%, 0.07%, and 0.09% respectively. Fat and fiber were not present in both Natron and its alternatives. The appreciable amount of ash content in the food additives indicated good mineral preservation capacity. Parkia wood ash may contain toxic chemical substances that may affect the kidney and liver.
Policy Landscape for Customary Forest Management in the Philippine Cordilleras
Authors: Abayao Leah
Published: November 2021

Forest management strategies in the Philippines recognize the cultural attributes of forests and customary practices accorded to them. Local communities view forests as an essential and contiguous resource. The Philippine Cordilleras is home to local community forests, natural and man-made or built. Natural forests are held collectively and managed according to customary practices. Man-made forests are developed by kin groups. These are small patches of forests that when surveyed make up a significant portion of the community’s natural resources. The “principle of collective ownership of forests” and the “customary tenurial security” are important principles in sustainable forest management in the Philippine Cordilleras. Agencies and local government units (LGUs) are challenged to strengthen their capacity to proactively encourage contemporary customary principles and practices to be used alongside official processes. These customary principles, when used within existing platforms, will prepare communities to face issues that affect their customary forests. Forests in some parts of the Cordilleras are tenured customarily, and such tenure comes with responsibility under the customary regime. The customary regime needs to be given equal attention in official processes to strengthen and effectively enforce forest local governance.
Leadership behavior of deans as a determinant of faculty job satisfaction and job commitment
Authors: Ballena Naressia Seludo
Published: November 2021

Background: Faculty job satisfaction and commitment contribute to the success of academic programs of a college. The main purpose of the study was to determine the relationship of leadership behavior of the deans of nursing colleges to the job satisfaction and job commitment of the faculty members.Methods: The study used a descriptive correlational design. Twenty deans and 100 faculty members from 20 nursing colleges in the National Capital Region, Philippines participated. Survey instruments used were the (1) modified Leader Behavior Description Questionnaire, (2) modified Minnesota Job Satisfaction Questionnaire, and (3) Job Commitment Questionnaire. Leadership behavior was measured based on the “initiating structure” and “consideration” dimensions.Results: Deans of nursing schools viewed their leadership behavior as “highly initiating” (M = 44.0, SD = 5.61) and “very highly considerate” (M = 50.1, SD = 4.99). Assessment of faculty members revealed congruent findings for the leadership dimensions of initiating structure (M = 46.6, SD = 3.83) and consideration (M = 49.9, SD = 2.66). Faculty members were generally “satisfied” (M = 4.20, SD = .25) and “committed” (M = 4.00, SD = .23) to their teaching job. Among the recently established colleges, the “initiating structure” dimension was highly positively correlated with job commitment of faculty members, r = .82, p < .05. There were no statistically significant relationships between the school classification, and the job satisfaction and job commitment of nursing faculty members.Conclusions: Measures must be instituted to improve the “initiating structure” behavior of deans of recently established nursing schools to increase job commitment of faculty members. Other factors associated with job satisfaction and job commitment should be explored.

Microclimatic modifications are the effective and suitable adaptation strategy to minimize the adverse affect of weather on cotton. In this context, multi-location field experiments were laid out at Bathinda and Faridkot, districts of Punjab during Kharif 2018 with Bt-cotton hybrid RCH 773 BGII and sown at three times i.e., April 30, May 15 and May 30 with two row orientations (North-South: N-S and East-West : E-W) and three plant spacing’s (67.5 cm × 45.0 cm, 67.5 cm × 60.0 cm and 67.5 cm × 75.0 cm) in factorial split plot design and replicated by three times. The results revealed that during the morning (0730 IST) and afternoon time (1430 IST), soil and within-canopy temperature were found higher during emergence and mid growth stages with delayed sowing which reduced the crop growing period and resulted the seed cotton yield to be declined with delayed sowing. On the other hand, morning and afternoon within-canopy relative humidity was recorded higher with delayed sowing during sensitive stages of the crop which provided favorable weather for higher infestation of cotton insect-pest and disease and caused reduction in seed cotton yield at both the study locations. Soil temperature and within-canopy temperature were recorded higher in East-West row oriented, while within-canopy RH was higher under North-South row orientation at both the study regions. During entire growth period of cotton, soil temperature and within-canopy temperature recorded during morning and afternoon hours were found to be increased with increase in plant spacing whereas within-canopy relative humidity during morning and afternoon hours was found to be decreased with increase in plant spacing at both the locations. Among microclimatic parameters, higher variation was observed between sowing dates, while lesser variation was recorded among row orientations and plant spacings.
Indian Ocean Dipole : Assessing its impacts on the Indian Summer Monsoon Rainfall (ISMR) across North East India
Authors: SARKAR PARTHAPRATIM , JANARDHAN PRASHANTH , ROY PARTHAJIT
Published: November 2021

The Indian Ocean Dipole (IOD), a climatic anomaly, results in sustained sea surface temperature (SST) variations between tropical western and eastern Indian Ocean temperatures. In this study, we studied the variations to inculcate the teleconnections between IOD and Indian summer monsoon rainfall (ISMR) distribution across the country for the period 1960-2020 for all the three phases of ISMR. We analyzed rainfall, SST and low-level wind circulation anomalies for the above mentioned time horizon. Positive IOD events noticeably resulted in increase in summer monsoon rainfall distribution across the country respectively while its negative counterpart led to decrease in rainfall except for the commencement phase of ISMR. The variations in SST, wind circulation and moisture movement processes across the Indian Ocean characterize significant changes in rainfall during the positive and negative phases of IOD especially during the recent decades (1991-2020). The recent time horizon also witnesses enhanced low-level equatorial jets (LEJ) across the equatorial Indian Ocean and the Arabian Sea during the positive IOD events as compared to the prior decades (1960-1990). The effect of moisture convergence zone is also analyzed which results in above rainfall conditions across northeastern and central India. Conversely, negative IOD events were found to subdue any such moisture movement mechanisms. Furthermore, and additional investigation to analyze the effect of IOD on the retreating/withdrawal monsoon across northeast India has been done and it has been observed that a stronger positive IOD is detrimental to the seasonal rainfall (May- September) over North East India (-0.7 one month lag correlation). Furthermore, the DMI index of April-May presented a clear indication of monsoon activity over the area during the withdrawal or retreating phase of the summer monsoon, i.e., during September.

Published: November 2021

A participação da família na rotina educacional dos filhos pode trazer benefícios para todos os sujeitos envolvidos nesse processo e para a gestão escolar. O estudo buscou compreender as concepções de mães e pais de alunos do Ensino Fundamental acerca da competência social dos professores dos filhos. Participaram oito mães e oito pais, cada metade de escolas públicas e privadas. Uma entrevista semiestruturada foi realizada individualmente com cada participante. Os dados coletados foram analisados através do software IRAMUTEQ. Os resultados indicaram similaridades entre as concepções dos dois grupos ao demonstrar a expectativa de que os comportamentos dos docentes sejam favoráveis a interação dos alunos, promovam sua aprendizagem, ofereçam apoio em suas dificuldades e permitam uma correção disciplinar adequada. As diferenças foram que os pais aparentaram ter uma visão mais distanciada do universo educacional, levando-os a apresentar concepções mais preocupadas acerca dos comportamentos dos professores em relação aos resultados das mães.

Published: November 2021

A pandemia da COVID-19 provoca inúmeros impactos na saúde mental, que variam desde reações esperadas de estresse agudo até agravos que podem descompensar condições psicopatológicas preexistentes ou deflagrar novas. O objetivo deste estudo é identificar e analisar fatores de risco para o suicídio que podem ser exacerbados pela situação de emergência sanitária global. A revisão narrativa permitiu mapear os seguintes fatores de risco: luto complicado, insegurança econômica, isolamento social, violência doméstica, abuso de álcool e drogas, barreiras no acesso ao sistema de saúde e às redes de suporte comunitário, psicossocial e espiritual, riscos inerentes às situações de hospitalização e vulnerabilidade dos profissionais da linha de frente. Também foram abordados aspectos que podem funcionar como proteção e métodos de prevenção/posvenção ao suicídio. A situação pandêmica eleva a vulnerabilidade ao comportamento suicida, porém os efeitos deletérios podem ser mitigados com estratégias de proteção à saúde mental, que devem ter prioridade na agenda de saúde pública.
An outline of extension from Neutrosophic Psychology to Pneumatic Transpersonal Psychology: Towards Relational Psychotherapy and Relational Pedagogy
Authors: Christianto Victor
Published: November 2021

Continuing our previous paper, we gave an outline of a new integral model of human consciousness scheme beyond Freudian mental model. We start from a recent book by one of us: Neutropsychic personality. Then we discuss possibility to reintroduce spirit into human consciousness. To emphasize what we have outlined in a preceding paper, we consider the following: that human consciousness model should take into consideration “spirit” role, i.e. the mind-body-spirit as integral aspect, which view is neglected in the Freudian mental model. In this paper, we consider a further step: introducing “soul” as a different element of human consciousness. We also discuss a few possible applications of such an integral model of human consciousness, including relational psychotherapy and relational pedagogy. While we are fully aware that much remain to be done and we admit that this is only a sketch, we hope that this paper will start a fresh approach of research towards more realistic nonlinear human consciousness model.

Melanjutkan makalah kami sebelumnya, kami memberikan garis besar model integral baru skema kesadaran manusia di luar model mental Freudian. Kita mulai dari sebuah buku baru-baru ini oleh salah satu dari kita: kepribadian Neutropsik. Kemudian kita membahas kemungkinan untuk memperkenalkan kembali roh ke dalam kesadaran manusia. Untuk menekankan apa yang telah kami uraikan dalam makalah sebelumnya, kami mempertimbangkan yang berikut: bahwa model kesadaran manusia harus mempertimbangkan peran "roh", yaitu jiwa-raga-jiwa sebagai aspek integral, yang pandangannya diabaikan dalam model mental Freudian. Dalam tulisan ini, kami mempertimbangkan langkah selanjutnya: memperkenalkan "jiwa" sebagai elemen berbeda dari kesadaran manusia. Kami juga membahas beberapa aplikasi yang mungkin dari model integral dari kesadaran manusia, termasuk psikoterapi relasional dan pedagogi relasional. Sementara kami sepenuhnya menyadari bahwa masih banyak yang harus dilakukan dan kami mengakui bahwa ini hanya sketsa, kami berharap makalah ini akan memulai pendekatan penelitian baru menuju model kesadaran manusia nonlinier yang lebih realistis.

Kajian Perjanjian Lama Tentang Pembelajaran di Rumah Pada Masa Pandemi Covid-19 di SD Pesat Wamena
Authors: Padabang Yosep Iswanto
Published: November 2021

Pembelajaran di rumah pada masa pendemi Covid-19 dilaksanakan oleh Lembaga Pendidikan dengan pola yang baru. Hal ini memunculkan persoalan clasik antara guru selaku pendidik disekolah dan orang tua yang tentunya berdampak pada efektivitas pembelajaran anak di rumah. Persoalan mendasar yang muncul adalah bahwa terdapat sebagian orang tua di SD Triesa Unggul PESAT Wamena yang mengemukakan bahwa anak mereka cenderung merasa bosan dan tidak ingin belajar karena guru hanya memberikan catatan yang dicatat oleh anak di rumah tanpa memberikan penjelasan. Sementara orang tua di rumah pun terbatas didalam mendampingi anak. Pada sisi lain, dalam Alkitab Perjanjian Lama terdapat banyak rujukan yang memberi penekanan mengenai pembelajaran di rumah. Penulis menggunakan metode kualitatif research dengan pendekatan library dalam upaya elaborasi yang terkait dengan topik yang dibahas. Pada akhirnya disimpulkan bahwa pembelajaran di rumah perlu dilakukan berdasarkan pola Allah yang menegaskan mengenai tanggung jawab orang tua dan guru di sekolah dalam hal mendidik anak untuk mengenal Tuhan dan dapat mengaktualisasikan dirinya dalam kehidupan sehari.
Familiar Wikidata: The Case for Building a Data Source We Can Trust
Authors: Crompton Constance , Antranikian Lori , Truong Ruth , Maskell Paige
Published: November 2021

Wikipedia is far from perfect. The same can be said of its sister project, Wikidata. And yet, excluding the World Wide Web itself, Wikipedia and Wikidata together represent the world’s largest structured humanities data source. This methods paper offers an introduction to the value of Wikidata for humanities research and makes the case for humanities researchers’ intervention in its development. It concludes with a short case study to illustrate how Wikidata can support humanities research projects. The case study project, Linked Familiarity, uses Wikidata data about the people quoted in the first ten editions of Bartlett’s Familiar Quotations to look for patterns in the people Bartlett’s Familiar editorial team thought readers find quotable from 1855 and 1910. These patterns will, we hope, clarify a corner of the zeitgeist: Bartlett’s Familiar Quotations readers voted with their purchases—the book’s popularity suggests the quotes the volume’s editorial team compiled really did meet a public desire, or even need. The Linked Familiarity’s team is using Wikidata data to find out about the people worth quoting in this 55-year stretch, to examine the characteristics that unite them, and to uncover the outliers.
Scriptorium: Creating an Open-Access Creative Writing Journal in Brazil
Authors: Bueno Bernardo
Published: November 2021

Since 2012, Creative Writing has been an official concentration within the Graduate Program in Letters at the Pontifical Catholic University of Rio Grande do Sul (PUCRS) in Porto Alegre, Brazil. PUCRS is still the only institution offering Creative Writing courses across all levels (undergraduate, MA, PhD, workshops, non-credit courses) in the country. Within this context, we created Scriptorium, our first Creative Writing Studies journal. Linked to the Graduate Program in Letters and EDIPUCRS (the university press), Scriptorium publishes articles on the creative process, literary translation, Creative Writing pedagogy, as well as fiction and poetry. In our editorial team, we have faculty members, graduate, and undergraduate students. Every article is peer-reviewed, and the journal is open access and published online. The present paper aims to offer an account of the creation of our journal, drawing from my experience as editor. I will share our publishing process, the challenges in the dialogue between Creative Writing and Academia in Brazil, and our views for the future of this kind of publication, hoping that our experience can prove useful to other researchers and institutions wanting to publish similar open access journals.
Where Lie the Similarities and Differences?: A Comparison of University and Industry Partners in Collaboration
Authors: Siemens Lynne
Published: November 2021

University–industry partnerships are common on the science side of campus where ways to work together are well understood. This is less so in the humanities even as these types of collaborations are being funded by granting agencies and governments. For these partnerships to build a foundation for success, common understandings around issues of the nature of collaboration, benefits, challenges, measures of success and outcomes need to exist. Using Implementing New Knowledge Environments (INKE) as a study case, this research examines a humanities-based partnership to understand similarities and differences in partners’ perspectives around these factors. Overall, the university and industry partners have common understandings of the nature of collaboration, the potential challenges facing the collaboration, and desired outcomes and success factors. However, there are some differences that must be navigated to ensure collaboration success. These focus on the benefits, the role of industry partners, need for tenure and promotion for researchers, and the type of resources that each can provide. While the partnership is in early stages of research, it has had the opportunity to learn about each other and differing perspectives by working and meeting together for over five years. This is the first step to creating a foundation of trust upon which a successful collaboration can be built.
The Open Scholarship Commons: Advancing Research for the Public Good
Authors: Kern Verletta , Mundt Madeline
Published: November 2021

The ground is shifting at our educational institutions. We are asked to demonstrate the value of our research to a wider public, particularly as public funding comes with requirements of openly sharing funded research results. At the same time, we are witnessing an educational shift from students as consumers of knowledge to students as co-creators of new knowledge. How can libraries, the traditional keepers and guardians of knowledge, grow to support this changing world? Our library will offer a new space that brings together partners at our academic institution to support the entire research cycle from the conception of an idea to the creation and dissemination of new knowledge in service of advancing research for the public good. Through this paper, we will share our process for creating this new space and how it will open opportunities for the production and sharing of scholarship beyond the academy.
A sketch for the KS test for Big Data
Authors: Galeno Thalis D. , Gama João , Cardoso Douglas O.
Published: November 2021

Motivated by the challenges of Big Data, this paper presents an approximative algorithm to assess the Kolmogorov-Smirnov test. This goodness of fit statistical test is extensively used because it is non-parametric. This work focuses on the one-sample test, which considers the hypothesis that a given univariate sample follows some reference distribution. The method allows to evaluate the departure from such a distribution of a input stream, being space and time efficient. We show the accuracy of our algorithm by making several experiments in different scenarios: varying reference distribution and its parameters, sample size, and available memory. The performance of rival methods, some of which are considered the state-of-the-art, were compared. It is demonstrated that our algorithm is superior in most of the cases, considering the absolute error of the test statistic.
How concept drift can impair the classification of fake news
Authors: Silva Renato M. , Almeida Tiago A.
Published: November 2021

Fake news is a serious problem that can influence political choices, harm people's physical and mental health, promote treatments without scientific evidence, and even incite violence. Machine learning methods are one of the leading solutions that have been studied for filtering fake news automatically. However, most studies do not consider the dynamic nature of news, creating static models and evaluating them offline through the traditional holdout or cross-validation. These studies naively assume that news characteristics do not change over time and, therefore, the performance of offline models is preserved as time goes on. In this study, we show how concept drift can impair the classification of fake news. We aim to verify whether the conclusions obtained in studies that disregarded the dynamic nature of the news are sustained. We analyzed how the performance of methods trained in an offline fashion is affected by the news update over time, including concept drift due to impacting events like the Covid-19 pandemic and the United States presidential election. The results showed that the performance of offline models is over-optimistic. Incremental learning methods should be preferred because they can adapt to changes in textual patterns over time.
Combining Clustering and Regression Models for Recommending Researchers
Authors: Lima Jaimel de Oliveira , Oliveira Elias
Published: November 2021

Due to the increase in scientific production, especially in recent years, management and decision support challenge also increase significantly. The task of recommending researchers, for example, to a project is not simple. Even with the proper amount of data, ranking and recommending researchers becomes a challenging process. Despite the different methods, what can happen is that the datasets of an institution or research areas do not have a ranking value, that is, a value that can be used to assess the position of a researcher. Even having a necessary dataset, there is no ranking information for these researchers, and this process of obtaining data for training a model can be costly. We propose to use clustering techniques to support the ranking process, reducing the human effort to obtain examples for models training. Then, we used this dataset to train the regression models and Mean Squared Error (MSE) and Normalized Discounted Cumulative Gain (nDCG) to evaluate them. Tests demonstrate that our solution can support the researchers' recommendation process in an adaptive process to the needs of an organization.
Characterizing and understanding ensemble-based anomaly-detection
Authors: Avelar Gustavo de P. , Campos Guilherme O. , Meira Jr. Wagner
Published: November 2021

Anomaly Detection (AD) has grown in importance in recent years, as a result of an increasing digitalization of services and data storage, and abnormal behavior detection has become a key task. However, discovering abnormal data that is mixed with the huge amount of data available is a daunting problem and the efficacy of the current methods depends on a wide range of assumptions. One effective strategy for detecting anomalies is to combine multiple models, which are called "ensembles", but the factors that determine their performance are often hard to determine, making their calibration and improvement a challenging task. In this paper we address these problems by employing a four-step method for the characterization and understanding of ensemble-based anomaly-detection task. We start by characterizing several datasets and analyzing the factors that make it hard to detect their anomalies. We then evaluate to what extent existing algorithms are able to detect anomalies in the same datasets. On the basis of both analyses, we propose a stacking-based ensemble that outperformed a state-of-the-art baseline, Isolation Forest. Finally, we examine the benefits and drawbacks of our proposal.

Grain boundary diffusion (GBD) of multiple rare earths has proven effective in enhancing the performance of permanent magnets, whereas the diffusion behaviors are still unclear due to their intricate interactions. In this work, the synergistic effects of three rare earths (Tb, Ce, and La) on the grain boundaries diffusion process are investigated, achieving a high‐performance diffused Nd–Fe–B magnet with the high coercivity of 1822 kA m−1 and thermal stability of −0.447% K−1. This promotion originates from the improved diffusion depth of Tb at specific regions, induced by the coordination effects of Ce and La, as evidenced via electron probe microanalysis and the first‐principles calculations. It thus results in the uniform formation of Tb‐diffused magnetic harden grains, associated with the strongly pinned domain walls, which is further observed directly by in situ Lorentz transmission electron microscopy and reconstructed by micromagnetic simulations. The study provides insight into the role of element GBD mechanism and has promising potential to explore other element systems as diffusion sources for permanent magnets.
A Dry‐Processed Al2O3/LiAlO2 Coating for Stabilizing the Cathode/Electrolyte Interface in High‐Ni NCM‐Based All‐Solid‐State Batteries

Due to their high theoretical energy densities and superior safety, thiophosphate‐based all‐solid‐state batteries (ASSBs) are considered as promising power source for electric vehicles. However, for large‐scale industrial applications, interfacial degradation between high‐voltage cathode active materials (CAMs) and solid‐state electrolytes (SSEs) needs to be overcome with a simple, cost‐effective solution. Surface coatings, which prevent the direct physical contact between CAM and SSE and in turn stabilize the interface, are considered as promising approach to solve this issue. In this work, an Al2O3/LiAlO2 coating for Li(Ni0.70Co0.15Mn0.15)O2 (NCM) is tested for ASSBs. The coating is obtained from a recently developed dry coating process followed by post‐annealing at 600 °C. Structural characterization reveals that the heat treatment results in the formation of a dense Al2O3/LiAlO2 coating layer. Electrochemical evaluations confirm that the annealing‐induced structural changes are beneficial for ASSB. Cells containing Al2O3/LiAlO2‐coated NCM show a significant improvement of the rate capability and long‐term cycling performance compared to those assembled from Al2O3‐coated and uncoated cathodes. Moreover, electrochemical impedance spectroscopy analysis shows a decreased cell impedance after cycling indicating a reduced interfacial degradation for the Al2O3/LiAlO2‐coated electrode. The results highlight a promising low‐cost and scalable CAM coating process, enabling large‐scale cathode coating for next‐generation ASSBs.

The timely arrival of novel materials plays a key role in bringing advances to society, as the pace at which major technological breakthroughs take place is usually dictated by the discovery rate at which novel materials are identified within chemical space. High‐throughput experimentation and computation strategy, now widely considered as a watershed in accelerating the discovery and optimization of novel materials in virtually every field, enables simultaneous screening, synthesis and characterization of large arrays of different material classes toward identification of the lead candidates for given system and targeted application. However, the ability to acquire data, through the continued advancement of automation platforms and workflows especially in the field of battery research and development, often outpaces the ability to optimally leverage obtained data for improved decision‐making. Closing this gap inevitably calls for adapted algorithms, development of reliable predictive models and enhanced integration with machine learning, deep learning, and artificial intelligence. This Review aims to highlight state‐of‐the‐art achievements along with an assessment of current and future challenges as well as resulting perspectives toward accelerated development of advanced battery electrolytes and their interfaces.

This study assessed the psychological predictors of preferences for return of comprehensive tumor genomic profiling (CTGP) results in patients with advanced cancers, enrolled in the Molecular Screening and Therapeutics Program. Patients completed a questionnaire prior to undergoing CTGP. Of the 1434 who completed a questionnaire, 96% would like to receive results that can guide treatment for their cancer, and preference for receiving this type of result was associated with lower tolerance of uncertainty. Sixty‐four percent would like to receive results that cannot guide treatment, and lower tolerance of uncertainty, self‐efficacy, and perceived importance were associated with this preference. Fifty‐nine percent would like to receive variants of unknown significance, which was associated with lower tolerance of uncertainty, higher self‐efficacy, and perceived importance. Eighty‐six percent wanted to receive germline results that could inform family risk. This was associated with higher self‐efficacy, perceived importance, and perceived susceptibility. Although most patients wanted to receive all types of results, given the differing patient preferences regarding the return of results depending on the utility of the different types of results, it appears critical to safeguard patient understanding of result utility to achieve informed patient choices. This should be accompanied by appropriate consent processes.

Coronavirus disease‐2019 (Covid‐19) disrupted the in‐person teaching format of anatomy. To study changes in gross anatomy education that occurred during August–December, 2020 compared to before the pandemic, an online survey was distributed to anatomy educators. The 191 responses received were analyzed in total and by academic program, geographic region, and institution type. Cadaver use decreased overall (before: 74.1 ± 34.1%, during: 50.3 ± 43.0%, P < 0.0001), as well as across allopathic and osteopathic medicine, therapy, undergraduate, and veterinary programs (P < 0.05), but remained unchanged for other programs (P > 0.05). Cadaver use decreased internationally and in the US (P < 0.0001), at public and private (P < 0.0001) institutions, and among allopathic medical programs in Northeastern, Central, and Southern (P < 0.05), but not Western, US geographical regions. Laboratories during Covid‐19 were delivered through synchronous (59%), asynchronous (4%), or mixed (37%) formats (P < 0.0001) and utilized digital resources (47%), dissection (32%), and/or prosection (21%) (P < 0.0001). The practical laboratory examination persisted during Covid‐19 (P = 0.419); however, the setting and materials shifted to computer‐based (P < 0.0001) and image‐based (P < 0.0001), respectively. In‐person lecture decreased during Covid‐19 (before: 88%, during: 24%, P = 0.003). When anatomy digital resources were categorized, dissection media, interactive software, and open‐access content increased (P ≤ 0.008), with specific increases in BlueLink, Acland's Videos, and Complete Anatomy (P < 0.05). This study provided evidence of how gross anatomy educators continued to adapt their courses past the early stages of the pandemic.
Sustaining superior international performance: Strategic orientations and dynamic capability of environmentally concerned small‐ and medium‐sized enterprises
Authors: Zahoor Nadia , Lew Yong Kyu
Published: November 2021

This study examines the influence of strategic orientations and dynamic capability on the sustainable international performance of small‐ and medium‐sized enterprises (SMEs). Building on the dynamic capability perspective, we propose that the interaction between entrepreneurial orientation (EO) and alliance orientation (AO) facilitates dynamic capability and, in turn, the sustainable international performance of SMEs. Using survey data from 211 environmentally concerned SMEs in the United Arab Emirates, the study finds the significant effects of the interaction between EO and AO on dynamic capability. Further, the results support that dynamic capability mediates the interactive effect of EO and AO on international performance. The study shows that the SMEs benefit from balancing as well as pursuing two complementary strategic orientations (i.e., EO and AO) towards developing dynamic capability that contributes to making superior international performance.
Gradual adoption of needle biopsy for breast lesions in a rural state

Published: November 2021

Background

Minimally invasive breast biopsy (MIBB) is the standard of care for the diagnosis of breast cancer, with consensus guidelines suggesting MIBB goals of 90% of total biopsies. In a previous study of patients in the rural state of Vermont, USA (population size of 640,000), rural breast cancer patients had open biopsies 42% of the time compared to 29% of urban breast cancer patients. The aim of this study was to assess overall population‐based biopsy trends in Vermont.

Methods

The Vermont Breast Cancer Surveillance System (VBCSS) was used to identify women receiving MIBB and excisional breast biopsies in Vermont. Patient zip code at the time of initial biopsy was used to determine the patient residence rurality by rural–urban commuting area codes (RUCA 2.0™).

Results

There were 9122 diagnostic episodes from 1999 to 2018. MIBB was the initial biopsy method in 7524 (82.5%) cases, while surgical excision was the initial biopsy method in 1598 (17.5%) cases. A linear trend fit estimated an increase of 1.3% per year (p < 0.001, 95% CI 1.1%–1.5%) in the fraction of patients undergoing MIBB. Patients living in rural areas were less likely to receive MIBB (78.5%) than those living in urban areas (94.9%), p < 0.001. Multivariate analysis showed that urban patients and those patients in the years 2014–2018 were more likely to receive MIBB (OR 5.00, 95% CI 4.13–6.05 [p < 0.05] and OR 4.41, 95%CI 3.68–5.28 [p < 0.05], respectively). The rate of MIBB for rural patients increased and met the 90% quality standard in 2013 and ultimately matched urban patient rates of MIBB in 2018.

Conclusions

For the first time, we show that MIBB usage is above 90% in the state of Vermont and that there no longer exist disparities in breast biopsies between urban and rural patients or rural/urban facilities in the state, overall.
Corrosion of bauxite‐based refractory castables and matrix components in hydrogen containing atmosphere

Published: November 2021

For the transformation to a CO2 neutral industry, fuel of traditionally fossil‐fired furnaces is substituted by the subsequently addition of hydrogen. In these studies, refractory components are identified for the corrosion of refractories in (highly) reducing atmospheres. A bauxite‐based refractory castable is set up in diluted, 9Ar 1H2, hydrogen atmosphere. Additionally, a focus is set on the behavior of a common matrix phase, anorthite.

Corrosion experiments up to 1500°C using a tube furnace with the mentioned atmosphere have been scheduled. Amount and phase stability due to different time and temperature coordinates have been examined by XRD. Furthermore, the microstructure and in particular the bonding phase was observed by means of SEM and EDS. Microstructural components undergoing reaction or loss are identified and explained in regards of complete and incomplete hydrogen combustion. Reduction of impurities such as iron oxides, phosphorus oxides, and titanium oxides are considered in detail.

Authors: Liu Penggao , Liu Weifang , Liu Kaiyu
Published: November 2021

Currently, emerging battery technologies are being studied intensively. The lack of ideal electrode materials remains a key hindrance to further development of new batteries. The novel MXene material, due to its unique structural characteristics and physicochemical properties, shows the ability to enhance the electrochemical performance of the electrode. In addition to the adjustable layer spacing, because of excellent electrical conductivity, rich chemical composition, and controllable surface chemistry, MXene has the potential for use in diverse applications as an ideal electrode material in various battery systems. This review covers the recent progress achieved in research of the zinc‐ion energy storage of MXenes, including MXene‐based cathodes, MXene‐derived cathodes, MXene‐modified zinc anodes, and electrolyte additives. Moreover, further structural design and reaction mechanisms of MXenes in zinc‐ion storage are explored.

Published: November 2021

The contribution presents examples for electrochemical impedance spectroscopy data taken on automotive lithium‐ion battery cells. Discharge was done with the help of an external load. The measurements were done with an initial state of charge of about 97 %, at 23 °C and from 5000–0.1 Hz. Spectra were fitted with an equivalent circuit containing two RC elements and an inductance. For load currents up to 20 A and in certain regions of the used frequency range, it is possible to measure impedance spectra also under load that almost coincide with load‐free spectra.
The impact of the hidden curriculum on international students in the context of a country with a toxic triangle of diversity

The hidden curriculum, which refers to the ideologies that remain implicit in educational content, is often studied in the context of developed countries with a colonial past where there are efforts to redress the historical injustice of the colonial past. In this paper, we examine the impact of the hidden curriculum on international students in a country with a toxic triangle of diversity. The toxic triangle of diversity describes a context where there is extensive deregulation, voluntarism without responsibilisation of organisations, and absence of supportive organisational discourses for diversity. Most studies of the hidden curriculum have taken place in countries where there are national laws for equality, institutional responsibility to bias‐proof the curriculum, and supportive discourses for diversity. Drawing on a field study with nineteen international students (nine in the field of business studies and ten in other subject fields), we demonstrate how the hidden curriculum remains unattended and how it is legitimised through macro‐, meso‐ and micro‐level interactions that students have. We show that the hidden curriculum serves to silence different forms of exclusion, loneliness and discrimination that international students experience in the context of a toxic triangle of diversity. We suggest ways forward for undoing the damage done through the hidden curriculum in toxic contexts.
