Using Text Mining Techniques to Identify Health Care Providers With Patient Safety Problems: Exploratory Study (Preprint)
Authors: Hendrickx Iris , Voets Tim , van Dyk Pieter , Kool Rudolf B
Published: April 2020

BACKGROUND

Regulatory bodies such as health care inspectorates can identify potential patient safety problems in health care providers by analyzing patient complaints. However, it is challenging to analyze the large number of complaints. Text mining techniques may help identify signals of problems with patient safety at health care providers.

OBJECTIVE

The aim of this study was to explore whether employing text mining techniques on patient complaint databases can help identify potential problems with patient safety at health care providers and automatically predict the severity of patient complaints.

METHODS

We performed an exploratory study on the complaints database of the Dutch Health and Youth Care Inspectorate with more than 22,000 written complaints. Severe complaints are defined as those cases where the inspectorate contact point experts deemed it worthy of a triage by the inspectorate, or complaints that led to direct action by the inspectorate. We investigated a range of supervised machine learning techniques to assign a severity label to complaints that can be used to prioritize which incoming complaints need the most attention. We studied several features based on the complaints’ written content, including sentiment analysis, to decide which were helpful for severity prediction. Finally, we showcased how we could combine these severity predictions and automatic keyword analysis on the complaints database and listed health care providers and their organization-specific complaints to determine the average severity of complaints per organization.

RESULTS

A straightforward text classification approach using a bag-of-words feature representation worked best for the severity prediction of complaints. We obtained an accuracy of 87%-93% (2658-2990 of 3319 complaints) on the held-out test set and an F1 score of 45%-51% on the severe complaints. The skewed class distribution led to only reasonable recall (47%-54%) and precision (44%-49%) scores. The use of sentiment analysis for severity prediction was not helpful. By combining the predicted severity outcomes with an automatic keyword analysis, we identified several health care providers that could have patient safety problems.

CONCLUSIONS

Text mining techniques for analyzing complaints by civilians can support inspectorates. They can automatically predict the severity of the complaints, or they can be used for keyword analysis. This can help the inspectorate detect potential patient safety problems, or support prioritizing follow-up supervision activities by sorting complaints based on the severity per organization or per sector.

Authors: Humphries Sophia Monica , Rondung Elisabet , Norlund Fredrika , Sundin Örjan , Tornvall Per , Held Claes , Spaak Jonas , Lyngå Patrik , Olsson Erik M G
Published: April 2020

BACKGROUND

The involvement of patient research partners (PRPs) in research aims to safeguard the needs of patient groups and produce new interventions that are developed based on patient input. Myocardial infarction with nonobstructive coronary arteries (MINOCA), unlike acute myocardial infarction (MI) with obstructive coronary arteries, is presented with no significant obstructive coronary artery disease. Patients with this diagnosis are a subset of those diagnosed with traditional MI and often need more psychological support, something that is presently not established in the current treatment scheme in Swedish health care or elsewhere, to our knowledge. An internet-delivered intervention might offer patients with MINOCA the opportunity to access a psychological treatment that is tailored to their specific needs after MINOCA and could therefore supplement the existing medical care in an easily accessible format.

OBJECTIVE

This paper aims to describe the development of a therapist-guided, internet-delivered psychological intervention designed specifically for patients with MINOCA.

METHODS

The study used a participatory design that involved 7 PRPs diagnosed with MINOCA who collaborated with a team consisting of researchers, cardiologists, and psychologists. Intervention content was developed iteratively and presented to the PRPs across several prototypes, each continually adjusted and redesigned according to the feedback received. The intervention and experience of it were discussed by PRPs in a final meeting and then presented to a panel of 2 clinical psychologists and a cardiologist for further input.

RESULTS

The outcome of the collaboration between PRPs and the research group produced a web-based psychological 9-step program focusing on stress, worry, and valued action. The input from PRPs contributed substantially to the therapy content, homework tasks, interactive activities, multimedia, and design presentation.

CONCLUSIONS

Working with PRPs to develop an intervention for people with MINOCA produced a web-based intervention that can be further evaluated with the goal of offering a new psychological treatment option to a patient group currently without one. Direct contribution from PRPs enabled us to obtain relevant, insightful, and valuable feedback that was put towards the overall design and content of the intervention.
Effect of Voluntary Participation on Mobile Health Care in Diabetes Management: Randomized Controlled Open-Label Trial (Preprint)
Authors: Lee Da Young , Yoo Seung-Hyun , Min Kyong Pil , Park Cheol-Young
Published: April 2020

BACKGROUND

The role of mobile health care (mHealth) in glycemic control has been investigated, but its impact on self-management skills and its psychological aspects have not been studied.

OBJECTIVE

We evaluated the efficacy of mHealth-based diabetes self-management education and the effect of voluntary participation on its effects.

METHODS

This study was a randomized controlled open-label trial conducted for 6 months at Kangbuk Samsung Hospital. Participants in the control group (n=31) maintained their previous diabetes management strategies. Participants in the intervention group (n=41) additionally received mHealth-based diabetes self-management education through a mobile app and regular individualized feedback from health care professionals. The primary outcome was change in glycated hemoglobin (HbA1c) level over 6 months between the 2 groups (intervention versus control) and within each group (at 6 months versus baseline). The secondary outcomes were changes in body mass index, blood pressure, lipid profile, and questionnaire scores (the Korean version of the Summary of Diabetes Self-Care Activities Questionnaire, an Audit of Diabetes Dependent Quality of Life, the Appraisal of Diabetes Scale, and Problem Areas in Diabetes) over 6 months between groups and within each group.

RESULTS

A total of 66 participants completed this study. HbA1c (P=.04), total cholesterol level (P=.04), and Problem Areas in Diabetes scores (P=.02) significantly decreased; total diet (P=.03) and self-monitoring of blood glucose level scores (P=.01), based on the Summary of Diabetes Self-Care Activities Questionnaire, markedly increased within the intervention group. These significant changes were observed in self-motivated participants who were recruited voluntarily via advertisements.

CONCLUSIONS

mHealth-based diabetes self-management education was effective at improving glycemic control and diabetes self-management skills and lowering diabetes-related distress in voluntary participants.

Mathematical Predictions for Covid-19 as a Global Pandemic (Preprint)
Authors: Victor Alexander Okhuese
Published: April 2020

UNSTRUCTURED

The model equations which exhibits the disease-free equilibrium (E_0 ) state for COVID-19 coronavirus does not exist and hence does not satisfy the criteria for a locally or globally asymptotic stability when the basic reproductive number R_0=1 for and endemic situation. This implies that the COVID-19 coronavirus does not have a curative vaccine yet and precautionary measures are advised through quarantine and observatory procedures. The basic reproductive number was found to be R_0<1 and hence shows that there is a chance of decline of secondary infections when the ratio between the incidence rate in the population and the total number of infected population quarantined with observatory procedure.
Furthermore, numerical simulations were carried to complement the analytical results in investigating the effect of the implementation of quarantine and observatory procedures has on the projection of the further spread of the virus globally. Result shows that the proportion of infected population in the absence of curative vaccination will continue to grow globally meanwhile the recovery rate will continue slowly which therefore means that the ratio of infection to recovery rate will determine the death rate that is recorded globally.
Therefore, the effort to evaluate the disease equilibrium shows that unless there is a dedicated effort from individual population, government, health organizations, policy makers and stakeholders, the world would hardly be reed of the COVID-19 coronavirus and further spread is eminent and the rate of infection will continue to increase despite the increased rate of recovery until a curative vaccine is developed.

Telemedicine, which came into existence in its organized form in the late 1950s and promised to be at the forefront of the future of medicine, has not achieved the estimated success yet. It makes state-of-the-art healthcare highly accessible for everyone. However, the reality is that the concept has been adopted by only a handful of nations and for many of them, it has remained merely as a concept. This can be attributed to the lack of proper supportive infrastructure and awareness, reimbursement issues and legal restrictions. The ongoing global health crisis of COVID-19 has forced the regulatory bodies and healthcare providers to look for alternative healthcare service delivery modes and, telemedicine is being considered more and more as an ideal solution. In a state of complete lockdown, it allows remote consultation without any face-to-face contact, thus preventing any unnecessary exposure to an infection. Various national bodies and organizations such as The Academy of Family Physicians and the American Medical Association (AMA), besides the government of different nations including India, have released relevant telemedicine guidelines. It is a readily available solution especially for individuals on chronic medications for non-communicable diseases in addition to filtering out potential COVID-19 cases remotely. The pandemic has brought telemedicine into the limelight and it is the right time to strengthen the framework and incorporate additional features and services to make it disaster-ready for all times. Various aspects and opinions about the future of telemedicine and telehealth have been put forward here pivoting around the experiences at a telemedicine center in India. Can telemedicine have a significant impact on R-naught (R0) by cutting its right-side tail and pushing it below 1, thus contributing to the flattening of the COVID-19 curve? Our fight against public health crises in the future would rest a lot on this answer.

Published: April 2020

Objective: This study compared the maceration extraction method with non-conventional extraction methods such as ultrasound-assisted extraction(UAE) and microwave-assisted extraction (MAE).Methods: To obtain resveratrol, various conditions were optimized: Solvent types (organic solvent [i.e. 70% ethanol] and green solvents [i.e. naturaldeep eutectic solvent (NADES) and ionic liquid (IL)]) and extraction methods. The resveratrol content in the extracts was analyzed by high-performanceliquid chromatography.Results: It was determined that resveratrol extracted by UAE with NADES was composed of choline chloride–oxalic acid when the followingconditions were used: The solid/liquid ratio of 1:20 (g/mL) and the extraction time of 15 min. These conditions produced higher resveratrol content(0.049 mg/g dry weight) than that using MAE with 70% ethanol (0.011 mg/g dry weight). However, the maceration method yielded the highestamount of resveratrol (0.221 mg/g dry weight), and MAE with IL produced the smallest amount of resveratrol (0.157 × 10−3 mg/g dry weight).Conclusion: Peanut skin extracted using the maceration method produced the highest amount of resveratrol compared to that using other methods.

CSR reporting and ownership structure: Evidence from Italian listed companies
Authors: Fortuna Fabio , Ciaburri Mirella , Testarmata Silvia , Tiscini Riccardo
Published: April 2020

The paper empirically explores how firms’ Corporate Social Responsibility (CSR) disclosure varies according to their ownership structure. Three different kinds of ownership structures are considered: family firms (FFs), state-owned firms (SOFs) and firms with dispersed ownership (DOFs). It is the first study examining the relationship between CSR disclosure and ownership structure, which includes in the analysis also FFs and SOFs. The analysis is provided on a sample of 192 listed firms with reference to Italy, a suitable setting for the purpose of the study due to the considerable presence of both FFs and SOFs. Firstly, a content analysis on the CSR documents disclosed by the 192 firms is provided and then data are empirically analysed to test whether the ownership structure influences a firm’s CSR disclosure. Results show that FFs and SOFs disclose less CSR information and the explanation can be found in the lower level of agency problems they have to face. The paper contributes to the stream of literature about CSR disclosure, because it argues that the contents of CSR disclosure vary according to firm’s ownership structure and also to those about FFs and SOFs because it shows that the presence of a concentrated ownership lowers the level of CSR information disclosed.
Barefoot Engineers: The Non-Mobility of Knowledge in a Knowledge-Transfer Project
Authors: Allen Stewart
Published: April 2020

Knowledge transfer is an integral, yet oft neglected, component in the transfer of technology between different geographical and cultural milieus. This paper is based on fifteen months of participatory fieldwork within a CBO (community based organisation) in India that hosts up to thirty five participants at any one time from the ‘Least Developed Countries’ index to train them in the maintenance and repair of solar photovoltaic technologies. The trainees, all of whom are women, and ideally grandmothers, are instructed for six months, without a common medium of language instruction, in circuit board assembly, soldering, testing, maintenance and repair, through a ‘learning-by-doing’ process. After six months, the women return home to solar electrify their communities. In the following paper, I argue that knowledge is created and sustained dynamically through an on-going alignment of objects and symbols, gestures and bodies, identities and environment. Knowledge and meaning are not so much embedded or inscribed in these materials but rather performed through them in a dynamic coalescence of networked doing. By employing a network metaphor to describe the interplay of bodies and gestures, and not only material semiotic alliances, I hope to re-situate the centrality of lived interactions between persons and material objects in the dynamic becomings of network assemblages.
“The Past, Present, and Future of Accounting History”: A Comment on the State of Accounting History
Authors: Carnegie Garry D.
Published: April 2020

This response to the recent contribution by Matthews (2019) entitled “The Past, Present, and Future of Accounting History” specifically deals with the issues associated with concentrating on counting publication numbers in examining the state of a scholarly research field at the start of the 2020s. It outlines several pitfalls with the narrowly focused publications count analysis, in selected English language journals only, as provided by Matthews. The commentary is based on three key arguments: (1) accounting history research and publication is far more than a “numbers game”; (2) trends in the quality of the research undertaken and published are paramount; and (3) international publication and accumulated knowledge in accounting history are indeed more than a collection of English language publications. The author seeks to contribute to discussion and debate between accounting historians and other researchers for the benefit and development of the international accounting history community and global society.
Data Visualization in Local Accounting Firms: Is Slow Technology Adoption Rational?
Authors: Buchheit Steve , Dzuranin Ann C. , Hux Candice , Riley Mark E.
Published: April 2020

We survey highly experienced professionals from local accounting firms regarding the adoption of and perceived benefits from data visualization in audit practice. Although the majority of respondents have minimal experience with data visualization, local-firm partners have positive perceptions regarding the value that visualization can have on audit quality and client-related benefits. These perceptions are affected by visualization technology usage: perceived audit quality benefits increase with usage but client benefit perceptions decrease with usage. These results are consistent with competing models of technology adoption. In total, whether one labels a firm a “laggard” or a “rational nonadopter” of visualization, technology appears to be driven by whether the firm seeks to adopt technology in order to improve audit quality or to add value for their clients.
Chemotech International, Inc.: Accounting for International Differences in the Measurement of Raw Material and Work-in-Process Inventories
Authors: Long James H. , Nothhelfer Robert
Published: April 2020

This case involves initial and subsequent inventory measurement in an international setting. It provides students with: (1) a comprehensive review of inventory measurement issues under three accounting standard-setting regimes, and (2) a comparison of business cultures with respect to their financial accounting standards related to inventory, and (3) how they communicate information (e.g., dates and numbers). The modular nature of the case allows the instructor to assign one or two parts of the case and to apply one, two, or three sets of accounting standards. The first module involves accounting for raw materials inventories for an international chemical company according to U.S. and German GAAP. An optional extension addresses the IFRS inventory measurement requirements. In the second module, the inventory measurement issues are extended to semi-finished (work-in-process) inventories. The case is appropriate for intermediate, advanced, and graduate-level financial accounting classes.

Physical activity and social connectedness interventions in outdoor spaces among children and youth: a rapid review
Authors: Wray Alexander , Martin Gina , Ostermeier Emma , Medeiros Alina , Little Malcolm , Reilly Kristen , Gilliland Jason
Published: April 2020

Introduction

The rise in sedentary behaviour, coupled with the decline in overall mental health among Canadian children and youth in recent decades, demonstrates a clear need for applied research that focusses on developing and evaluating cross-disciplinary interventions. Outdoor spaces provide opportunities for physical activity and social connectedness, making them an ideal setting to address these critical health concerns among children and youth.

Methods

We conducted a rapid review of peer-reviewed (n = 3096) and grey literature (n = 7) to identify physical activity and/or social connectedness outdoor space interventions targeted at children and youth (19 years and under) in Australia and New Zealand, Canada, Europe and the United States. We determined if interventions were effective by analyzing their research design, confidence intervals and reported limitations, and then conducted a narrative synthesis of the effective interventions.

Results

We found 104 unique studies, of which 70 (67%) were determined to be effective. Overall, 55 interventions targeted physical activity outcomes, 10 targeted social connectedness outcomes and 5 targeted both. Play (n = 47) and contact with nature(n = 25) were dominant themes across interventions, with most taking place in a school or park. We report on the identifying features, limitations and implications of these interventions.

Conclusion

The incorporation of natural and play-focussed elements into outdoor spaces may be effective ways to improve physical activity and social connectedness. There is a considerable need for more Canadian-specific research. Novel methods, such as incorporating smartphone technology into the design and evaluation of these interventions, warrant consideration.
At-a-glance - Injuries and poisonings associated with methamphetamine use: sentinel surveillance, the electronic Canadian Hospitals Injury Reporting and Prevention Program (eCHIRPP), 2011–2019
Authors: McFaull Steven R. , Champagne André , Thompson Wendy , Bang Felix
Published: April 2020

Information from emergency department (ED) visits for methamphetamine-related injuries and poisonings between 1 April 2011 and 9 August 2019 were captured from 19 sentinel sites across Canada for all ages. Overall, 1093 cases (97.6/100 000 eCHIRPP cases) were identified (59.4% male), with female patients experiencing more poisonings (71% vs 57.4% for males). Unintentional injuries and poisoning accounted for 14.8% of ED presentations. Self-harm (while or as a result of consuming methamphetamine) accounted for 11.4% of cases. The circumstances surrounding injuries and poisonings associated with methamphetamine are varied and include self-harm, fall-related brain injuries, mental illness, criminal activity and other circumstances. These domains should be taken into account when developing mitigation strategies.
Factors determining company performance in the IT industry
Authors: Lungu Miruna Florina
Published: April 2020

The dynamics of the business environment indicate that companies should become more flexible and value oriented. The competition within the IT sector leads to increased uncertainty for the players and a higher focus on the strategic direction of the company. Hence, many studies point out the significance of strategic agility as a tool of increasing company performance and achieving improved results. The paper highlights how the performance of IT companies is impacted by various factors. The main driver for company performance is strategic agility mixed with absorptive capacity. For a better understanding, the paper will analyze knowledge acquisition, knowledge assimilation, transformation and knowledge exploitation. These four dimensions represent the layers of absorptive capacity. Using as framework a survey developed based on the literature, there will be performed an analysis of the input received. The responses have been captured from stakeholders of the IT industry, who are employees of IT organizations with operations in Romania. For an enhanced output, there will be applied a regression analysis. This will contribute to the identification of factors determining company performance in the IT industry. The results of the regression analysis will demonstrate that strategic agility, knowledge acquisition and transformation have the highest impact on company performance. As only three out of the five tested dimensions are validated, further research can be grounded on understanding why knowledge assimilation and knowledge exploitation have not been confirmed as factors impacting company performance.
Reflection of GDPR by the Czech Population
Authors: Tahal Radek , Formánek Tomáš
Published: April 2020

Nowadays, personal data is becoming both increasingly relevant and extensively shared over the internet. Individual privacy is often at risk as personal and contact information are a frequent object of commercial transactions. This situation recently triggered the implementation of a new data-protection regulation: General Data Protection Regulation (GDPR). This study analyses privacy protection from the citizens’ and consumers' points of view. The authors apply quantitative methods to primary data sampled from the population of the Czech Republic (aged 15+). Individual willingness to share personal data is evaluated along with the spectrum of situations where such data is requested and along with corresponding GDPR-related individual stances. According to the data analyzed, Czech population perceives GDPR measures as mostly useful yet somewhat bothersome. Also, individuals are not convinced that the regulation could deliver any fundamental changes to processes that involve handling of personal data. In general, respondents feel concerned by the intensification of demands for signing data sharing consents and by similar data processing interactions. However, individual levels of willingness to share various types of personal and contact information are sound and stable.

Published: April 2020

Subject. We consider the efficiency of comprehensive multi-storey development as an investment project and the main criteria for attracting borrowed funds through bond issue; analyze special features of the two-tier financing scheme for multi-storey development with a detailed calculation of values.
Objectives. The study aims to design a universal financing scheme with the possibility to modify parameters for specific investment projects in the construction sector for practical application by construction companies. We focus on developing an effective alternative to escrow accounts enabling better distribution of financial burden on the company over the entire life of investment project. It should ultimately prevent the increase in the price per square meter of residential and non-residential premises and the longer construction period.
Methods. We employ methods of analysis, synthesis and modeling of savings and credit scheme of financing.
Results. To simplify understanding the application of the bond loan by developers, we prepared a specific investment project for the existing construction company with a step-by-step calculation of the savings and credit financing scheme.
Conclusions. Earlier, the bond loan as a borrowing tool has not been detailed and formulated as a clear mechanism for funding company's activities. We offer our own description of the application of savings and credit scheme to finance projects for comprehensive multi-storey development with step-by-step calculations.

Published: April 2020

RESUMO: Na democracia liberal a obediência ao direito positivo se prende ao fato de que as normas são produzidas por poderes constitucionalmente estabelecidos, de modo que o ordenamento jurídico é visto como expressão de soberania. Esse postulado tangencia o conceito de Direito Transnacional, daí se falar em défice democrático. A justificação dessas normas passa por construções doutrinárias pós-liberais. O artigo analisa quatro dessas construções legitimadoras do Direito Transnacional, propostas por quatro pensadores alemães: Karl Emil Maximilian Weber, Niklas Luhmann, Günther Teubner e Lars Viellechner. A hipótese contestável é no sentido de que há pontos em comum, a serem identificados, nessas quatro correntes de pensamento sobre legitimidade normativa
Arbitration of oil contracts in oil-producing Arab Countries
Authors: Al-Qaaida Mousa Sami
Published: April 2020

This study investigates the most important legal matters of arbitration of Arab oil contracts. It has focused on the independent nature of arbitration, and the distinguished characteristics which make arbitration the most preferable means to settle international economic disputes. The study as well as sheds light on the arbitration agreement which included in the oil contracts in a way that excludes this agreement from the legal rules that usually prevent such agreements from developing in scope and content on the one hand, whereas on the other hand the study takes a look on the arbitration tribunal resulting from the arbitration agreement that included in the oil contracts which have special characteristics that distinguishes them from any other contracts in other economical and trading ventures.
This study has concluded that it is better for the disputes resulting from the oil contracts to be resolved via arbitration without necessarily arbitrated affecting the judicial immunity function. additionally, settlement of disputes in issuing the arbitration decision should be voluntarily implemented by the two parties in conflict. Finally, the researcher recommends arbitration as the only viable tool for settling conflicts/disputes of oil contracts in oil producing Arab nations because it’s the fastest, most reliable, least expensive and time saving method of conflict resolution.
Stereoselective Synthesis of Unnatural α-Amino Acids through Photoredox Catalysis
Authors: Shatskiy Andrey , Axelsson Anton , Blomkvist Björn , Liu Jian-Quan , Dinér Peter , Kärkäs Markus
Published: April 2020

A protocol for stereoselective C-radical addition to a chiral glyoxylate-derived sulfinyl imine was developed through visible light-promoted photoredox catalysis, providing a convenient method for the synthesis of unnatural α-amino acids. The developed protocol allows the use of ubiquitous carboxylic acids as radical precursors without prior derivatization. The protocol utilizes near-stoichiometric amounts of the imine and the acid radical precursor in combination with a catalytic amount of an organic acridinium-based photocatalyst. The mechanism for the developed transformation is discussed and the stereodetermining radical addition step was studied by the DFT calculations.
Anions Enhance Rare Earth Adsorption at Negatively Charged Surfaces
Authors: Nayak Srikanth , Lovering Kaitlin , Bu Wei , Uysal Ahmet
Published: April 2020

Anions are expected to be repelled from negatively charged surfaces. At aqueous interfaces, however, ion-specific effects can dominate over direct electrostatic interactions. Using multiple in situ surface sensitive experimental techniques, we show that surface affinity of SCN- ions are so strong that they can adsorb at a negatively charged floating monolayer at the air/aqueous interface. This extreme example of ion-specific effects may be very important for understanding complex processes at aqueous interfaces, such as chemical separations of rare earth metals. Adsorbed SCN- ions at the floating monolayer increase the overall negative charge density, leading to enhanced trivalent rare earth adsorption. Surface sensitive X-ray fluorescence measurements show that the surface coverage of Lu3+ ions can be triple of the apparent surface charge of the floating monolayer in the presence of SCN-. Comparison to NO3- samples show that the effects are strongly dependent to the character of the anion, providing further evidence to ion-specific effects dominating over electrostatics.

Published: April 2020

Characterisation of immobilised oxidase biocatalysts allowing multifunctional oxidation of valuable chemicals is described. Engineered galactose oxidase (GOase) variants M1 and M3-5, an engineered choline oxidase (AcCO6) and monoamine oxidase (MAO-N D9) displayed long-term stability and reusability over several weeks when covalently attached on solid support, outperforming their free counterparts in terms of stability, resistance to heat, and tolerance to neat organic solvents. While immobilisation of oxidase biocatalysts improves properties that are critical for industrial implementation, they additionally showed versatility as the biocatalyst batches can be recovered, washed and reused multiple times for the oxidation of different substrates.
Photocatalytic N-Heteroarylation of Aldehydes via Formyl C‒ H Activation
Authors: Fuse Hiromu , Mitsunuma Harunobu , Kanai Motomu
Published: April 2020

A formal C‒H addition of N-heteroaromatics to aldehydes

was achieved using a binary hybrid catalyst system comprising an acridinium photoredox catalyst and a thiophosphoric acid organocatalyst. The reaction proceeded through the following sequence: 1) photoredox-catalyzed single-electron oxidation of a thiophosphoric acid catalyst to generate a thiyl radical, 2) cleavage of the formyl C‒H bond of the aldehyde substrates by a thiyl radical acting as a hydrogen atom transfer catalyst to generate acyl radicals, 3) Minisci-type addition of the resulting acyl radicals to N-heteroaromatics, and 4) a spin-center shift, photoredox-catalyzed single-electron reduction, and protonation to produce secondary alcohol products. This metal-free hybrid catalysis proceeded under mild conditions for a wide range of substrates, including isoquinolines, quinolines, and pyridines as N-heteroaromatics, as well as both aromatic and aliphatic aldehydes, and tolerated various functional groups. The reaction was applicable to late-stage derivatization of drugs and their leads.

Published: April 2020

写作在英语考试中获得高分并不是一件容易的事情，不仅要有语言质量，更要考虑到细节添加、逻辑通顺、衔接过渡等因素。但这些上层建筑的基石是语言质量， 没有正确的句子，其他一切都是空谈。因此，在写作评价中让学生充分辨识并改正错误就是重中之重的一个环节。本文试图在传统方法的基础上，进行新的尝试，改进并融合传统的教学方法，注重学生自主探究总结，从现象到本质，从而达到写作时尽量避免常见错误点、写后检查中能快速辨析并改正错误的效果，进而提高英语作文成绩。

Published: April 2020

Esta pesquisa está centrada na compreensão do alcance das atividades dos professores na promoção do letramento digital dos alunos, bem como a importância dada aos recursos tecnológicos para a prática docente, tendo o objetivo de compreender como os professores da Universidade Federal de Alagoas (UFAL) promovem o letramento digital de seus alunos, as interlocuções realizadas e a importância dos artefatos tecnológicos para a prática docente no ensino superior. Trata-se de uma pesquisa qualitativa, em que os dados foram obtidos por meio de entrevista, os quais foram analisados com o auxílio do software IRaMuTeQ. Foram analisadas entrevistas realizadas com oito professores, selecionados a partir da busca de seus nomes no site da instituição de ensino e, posteriormente, da apreciação de seus respectivos currículos na plataforma Lattes. O critério para a seleção dos professores se deu pela verificação da trajetória de formação e de experiência profissional destes na área das Tecnologias Digitais da Informação e Comunicação (TDIC). A partir dos resultados, observamos que os professores envolvidos na pesquisa estão preocupados em dar sentido ao uso das ferramentas e promover o letramento, pois existe a necessidade de que os alunos do curso de Pedagogia, futuros professores, saibam criar situações pedagógicas de ensino e aprendizagem com os recursos tecnológicos.
Ensino de Ciências e de Biologia sob a perspectiva histórico-crítica na literatura científica
Authors: Campos Raquel Sanzovo Pires de
Published: April 2020

Este trabalho trata-se de um levantamento bibliográfico das produções teóricas já realizadas na literatura (anais de eventos, revistas da área, livros e artigos divulgados no meio digital), com o objetivo de se entender como se dá a apropriação teórica e metodológica da Pedagogia Histórico-crítica (PHC) no ensino de Ciências e no Ensino de Biologia. Cientes de que a PHC tem como pilar os pressupostos teóricos e filosóficos do Materialismo Histórico-dialético, foi possível observar que há falta de rigorosidade metodológica e comprometimento teórico entre os trabalhos do ensino de ciências. Na mesma linha, a escassez de trabalhos que relacionam o ensino de Biologia às pedagogias críticas apontam que as contribuições da PHC no ensino de Biologia são, ainda, embrionárias.

Authors: Faria Filipe Pereira , Carneiro Marcelo Carbone
Published: April 2020

Neste trabalho buscamos estabelecer um panorama acerca do papel atribuído à experimentação no contexto das propostas relacionadas ao ensino de Física no Brasil. A partir dos referenciais analisados, foi possível observar as diferentes percepções acerca da utilização de atividades experimentais para o ensino das disciplinas científicas e, em especial, da Física desde o início do período republicano até as diretrizes nacionais curriculares para os cursos de formação de professores de Física. Dada a importância atribuída à utilização de atividades experimentais, foi possível concluir que compreender as etapas percorridas até o presente, em relação a esse aspecto do ensino de ciências, é de extrema relevância no sentido de contribuir para a superação de dificuldades históricas, bem como para o estabelecimento de novas diretrizes de formação de professores e de elaboração de materiais de ensino.

Published: April 2020

No presente artigo apresentamos os primeiros resultados de uma pesquisa maior que visa articular o estágio supevisionado aos fundamentos da Pedagogia Histórico-Crítica. Aqui tratamos do estágio supervisionado de observação em Ciências e Biologia. A sistematização da proposta busca contribuir com a formação inicial dos licenciandos partido do processo de observação, pois este caracteriza-se pelo momento em que os licenciandos se inserem nas escolas assistindo ao seu funcionamento e às aulas, tendo por base uma fundamentação teórica que permita aos estagiários potencializar sua capacidade analítica e crítica em relação ao seu futuro universo de atuação profissional. Apresentamos sua estruturação em dois momentos; o primeiro diz respeito à observação da situação escolar, compreendendo suas implicações à prática educativa, e o segundo, elencamos os elementos a serem observados durante as aulas de Ciências Naturais na perspectiva histórico-critica.

Diálogos entre conceitos e produto artesanal: uma experiência de integração do currículo da Matemática no ensino de PROEJA
Authors: Silva Luiz Galdino da , Pizzi Laura Cristina Vieira
Published: April 2020

Este estudo apresenta o  relato de uma prática docente que permeia a integração do currículo da matemática no primeiro período do curso Técnico em Artesanato, na modalidade Educação de Jovens e Adultos – PROEJA, do Instituto Federal da cidade de Maceió/AL, articulado às intervenções/argumentações e mediações ocorridas durante o percurso do trabalho matemático, buscando-se estabelecer pontes entre a teoria da integração curricular de Santomé (1998) e outros referenciais da Educação Matemática, com destaque para a contextualização dos saberes, a metodologia da resolução de problemas e a teoria dos campos conceituais. Nessa direção busca-se contribuir no aprimoramento de uma concepção de currículo integrado que justifique a defesa por um trabalho matemático no contexto escolar, que se enquadra a vida quotidiana dos sujeitos artesãos através de elementos presentes na cultura e no mundo do trabalho e pode ser concretizada a partir do processo de contextualização entre o saber do sujeito, através de experiências do seu quotidiano; o saber docente, representado na condução dos conhecimentos matemáticos pelo professor; e, o saber necessário ao mundo do trabalho. Espera-se contribuir em reflexões que levem a construção de propostas que possam auxiliar o ensino da matemática no universo da educação profissional de Jovens e Adultos.
