Authors: Wood F.E.
Published: February 2020

Published in Petroleum Transactions, AIME, Volume 86, 1930, pages160–167.

This paper is written primarily as a discussion of Dr. W.P. Haseman's paperon "A Theory of Well Spacing" and presents briefly the productionrecords, and intensity and rate of development in a large portion of the twoprincipal producing sands in the Salt Creek field, Wyoming. The study includes1350 wells, 160,000,000 bbl. production, well spacings varying from two toseven wells per 40 acres and early and late development.

The general conclusions to be derived from this study are:It is impossible to formulate a mathematical rule to apply to well spacingin the Salt Creek field.Each tract is a separate problem.Tracts first drilled produce the most oil, with many exceptions.Initial production is not a reliable index to the relationship between past, current, or future production.Wells which have produced the most oil in the past are not necessarilyyielding the greatest current production nor will they yield the greatestfuture production. In fact, wells which have yielded the greatest pastproduction will, in at least one-half the cases, make less oil currently or inthe future than wells which have produced a smaller quantity of oil in thepast.The following is a safe rule to apply in well spacing in the Salt Creekfield:if the drilling of an additional well on a tract results in asustained increased production, with prospects of making a profit, the tract isnot overdeveloped and additional wells might be drilled.

If the drilling of an additional well does not effect a sustained increase inthe production of a tract, the tract is fully developed.

Second Wall Creek Sand

The Second Wall Creek sand, covering 20,000 producing acres, is the principalproducing horizon in the Salt Creek field; 1610 wells are producing at thistime from this sand.

Gastruloids are aggregates of mouse embryonic stem cells that can be used to study key aspects of mammalian post-implantation development in vitro1–4. Gastruloids generated with previously published protocols do not generate somite-like structures4–6. Here, we describe a modified version of the gastruloids culture protocol5,6 that results in gastruloids that do generate somite-like structures in vitro (van den Brink et al., Nature, 2020)7. Under these conditions, about 50% of the gastruloids generated form structures with features that are characteristic of somites7.This protocol takes 6 days, with relatively little hands-on time. The protocol starts with the aggregation of the cultured cells. Then, the Wnt-agonist Chiron is added 2 days (48h) later. The medium of the aggregates is replaced 3 days (72h) after aggregation. To induce somite-formation, gastruloids are embedded in Matrigel 4 days (96h) after aggregation. After 5 days (120h) of culture, gastruloids resemble E8.5 mouse embryos. At this timepoint they can be fixed (fixative is added on day 5 and washed away on day 6 after overnight incubation in PFA) to prepare them for staining or microscopy experiments.

BackgroundFatigue is a common symptom in patients with rheumatism that is easy to ignore. In the absence of previous studies, our study aims to investigate the fatigue status, explore the potential predictors of fatigue and the effects of fatigue on health-related quality of life (HRQoL) among Chinese gout patients.MethodThis cross-sectional study was conducted from the Affiliated Hospital of Nantong University. A series of questionnaires were applied: Fatigue Scale-14 (FS-14), the 10 cm visual analog scale (VAS), the Patient Health Questionnaire (PHQ-9), the Generalized Anxiety Disorder questionnaire (GAD-7), the Pittsburgh Sleep Quality Index (PSQI), Health Assessment Questionnaire(HAQ), the Short Form 36 health survey (SF-36). Laboratory examinations were taken to obtain some biochemical indicators. Independent samples t-test, Mann–Whitney U-test, Chi-square analysis, Pearson /Spearman correlation, Stepwise linear regression and binary logistic regression were used to analyze the data.Results410 gout patients were included in this study. Among them, more than 50% patients reported physical fatigue in FS-14, severe disease, poor psychological status and reduced HRQoL were associated with fatigue. Multiple stepwise linear regression and binary logistic regression were applied and showed that pain, sleep quality, anxiety and depression were the potential predictors of fatigue. In addition, we found that the more severe the fatigue, the lower the patient’s HRQoL.ConclusionsFatigue among gout patients is exceedingly common. The results of this study suggested that rheumatologists should pay closely attention to gout patients who suffer from serious fatigue, especially those with pain, poorer sleep quality, anxiety and depression.

Objectives Inflammatory idiopathic myopathies (IIM) are a heterogeneous group of disorders, ranging from a muscle-specific autoimmune disease to a systemic one that are difficult to assess. Recent insights into IIM pathogenesis highlighted the role of interferon (IFN) in the pathophysiology. The aim of this study was to test if IFN serum levels can a use as a biomarker of disease activity in IIM. Methods IFN type I and II were measured using an ultrasensitive detection technology and assess the potential of IFN. Results One hundred and fifty-two patients (dermatomyositis (DM); n=50, anti-synthetase syndrome (ASyS); n=46, immune-mediated necrotizing myopathy (IMNM); n=32, inclusion body myositis (IBM); n=24) and 33 age-matched healthy donors were included. IFN-α levels were higher only in DM (0.07 pg/ml [0.03-0.23], p<0.005) and ASyS groups (0.07 [0.02-0.16], p<0.05) compared with controls (0.02 [0.01-0.05]). IFN-β was increased only in DM and IFN-γ among all IIM. IFN-α levels were correlated with disease activity in DM (r=0.76, p<0.0001). The predictive accuracy of IFN-α level to discriminate active and non-active disease was excellent as reflected by an area under the ROC-curve of 0.88. Using an IFN-α level cut-off above 0.11 pg/ml, the sensitivity was 75% and the specificity was 96% in DM patient. IFN-α and IFN-γ were correlated with disease activity in ASyS groups (r=0.55 and r=0.46 p<0.05)). Conclusions IFNs are promising biomarker for DM and ASyS disease activity.

Published: February 2020

Background: Coronavirus disease 2019 (COVID-19) caused by Severe Acute Respiratory Syndrome Corona virus 2 (SARS-COV-2) was first diagnosed in December 2019, Wuhan, China. Little is known about this new virus and it has the potential to cause severe illness and pneumonia in some people, therefore the development of an effective vaccine is highly desired.Methods: Immunoinformatics and statistical approaches were used in this study to forecast B- and T- cell epitopes for the SARS-COV-2 structural proteins (Surface glycoprotein, Envelope protein, and Membrane glycoprotein) that may play a key role in eliciting immune response against COVID-19. Different types of B cell epitopes (linear as well as discontinuous) and T cell (MHC class I and MHC class II) were determined. Moreover, their antigenicity and allergenicity were also estimated.Results: The antigenic B-cell epitopes exposed to the outer surface were screened out and 23 linear B cell epitopes were selected. “SPTKLNDLCFTNVY” had the highest antigenicity score among B cell epitopes. The T-cell epitopes bound to multiple alleles, antigenic, non-allergen, non-toxic, and conserved in the protein sequence were shortlisted. In total, 16 epitopes (9 from MHC class I and 7 from MHC class II) were selected. Among the T-cell epitopes, MHC class I (IPFAMQMAYRFN) and MHC class II (VTLACFVLAAVYRIN) were classified as strongly antigenic. Digestion analysis verified the safety and stability of the peptides predicted during this study. Furthermore, docking analyses of predicted peptides showed significant interactions with the HLA-B7 allele.Conclusion: The putative antigen epitopes identified in this study may serve as vaccine candidates and can help to eliminate/control growing health threat of COVID-19.

Authors: Ntopi Simon , Chirwa Ellen , Maluwa Alfred
Published: February 2020

Background: Health Surveillance Assistants (HSAs) are community-based health workers in Malawi, responsible for health services delivery at the community level. The prevalence of high role stressors among health surveillance assistants (HSAs) is a very important issue to strengthen the delivery of the essential health package at the community level; however, data on the prevalence of these role stressors to help understand more about the role stressors among HSAs is unavailable. This study aimed to investigate the prevalence of role stressors and its associated factors among HSAs. Methods: A cross-sectional study design was used in this study to collect data from January 2017 to December 2017. Data were collected from 430 HSAs from the districts of Mangochi, Lilongwe and Mzimba using a self-administered structured questionnaire was hand delivered to a total of 455 HSAs (response rate of 94.5%). Role ambiguity and role conflict was measured using a 13-item Rizzo et al. role conflict and ambiguity (RCA) scale; role overload was measured using a 9-item Reilly role overload scale and the job tasks for HSAs were measured using Burgal et al. modified version of the task inventory scale. Factors for role stressors were analyzed using the principal component analysis (PCA) and multiple linear regression model. Results: Of the respondents 3% had high risk for RA, 51.20% RC and 49% RO. Role stressors are prevalent among HSAs in Malawi. HSAs who were resident in rural areas, female, and performing additional clinical roles experienced significant levels of role stressors. Interestingly, no statistically significant associations were found between role stressors and the years at service post, age and the district of work. Conclusion: This is the first study of occupational role stressors in Malawi. Role stressors are prevalent among HSAs. Interventions aimed at improving supervision, training and task regulation by an independent regulatory body may support to reduce role stressors among HSAs.

A quantified discrimination of a query compound between target classes under 3D-similarity metric
Authors: Lee Sanghyeok , Ahn Sangjin , Kim Mi-hyun
Published: February 2020

Background: 3D similarity is useful to predict the profiles of unprecedented molecular frameworks, 2D dissimilar to known compounds. Basically, when comparing compound pairs, 3D similarity of the pairs depends on conformational sampling of compounds, alignment method, chosen descriptors, and metric to show limited discriminative power. In addition to four factors, 3D chemocentric target prediction of an unknown compound requires compound - target associations. The associations for the target prediction replace compound-to-compound comparison with compound-to-target comparison. Results: Quantitative comparison of query compounds to target classes (one-to-group) could be acquired using two type similarity distributions: one is from maximum likelihood (ML) estimation of queries and another is from Gaussian mixture model (GMM) of target classes. While Jaccard-Tanimoto similarity of query-to-ligand pairs could be transformed into query distribution through ML estimation, the similarity of ligand pairs within each target class could be transformed into the representative distribution of a target class through GMM, hyperparameterized through expectation-maximization (EM) algorithm. To quantify the discriminativeness of a query ligand against target classes, Kullback-Leibler (K-L) divergence was calculated between two distributions.Conclusions: Stratified sampled 14K ligands from four target classes, estrogen receptor alpha (ESR), vitamin D receptor (VDR), cyclooxygenase-2 (COX2), and cathepsin D (CTSD) presented whether or not each query can be a representative ligand of each target through compared K-L divergence value. The feasibility index, Fm and the probability, from K-L divergence could summarize 3D chemocentric relationship between target classes.
A split supply of bio-organic and chemical fertilizer synergistically affects root system architecture and improves above-ground growth in pear tree (Pyrus pyrifolia Nakai)

Published: February 2020

Background: Root system architecture (RSA) is highly plastic, responding to nutrient availability and the heterogeneity of the soil environment. However, the linkage of root morphology to anatomy and root nutrient, and its implication for root function at the heterogeneous application of bio-organic and chemical fertilizer have not yet been defined, especially for pear trees.Results: In this study, a split-root experiment was conducted using 1-year old ‘Cuiguan’ trees. No fertilizer (NF), chemical fertilizer (CF), and bio-organic fertilizer (BIO) were paired to test six combinations: NF-NF, NF-CF, NF-BIO, CF-CF, BIO-BIO, and BIO-CF. Root morphological, anatomical traits and root nutrient concentrations, and their relationships were determined. Trees receiving BIO had significantly higher lateral root numbers, activity, total lateral root length, and specific root length than trees receiving no BIO, while the effects on root tissue density were the direct opposite. Compared with CF-CF treatment, root xylem thickness, stele diameter, vessel diameter, and number of vessels all increased in response to BIO-CF treatment. Root growth was synergistically promoted in BIO-CF, with increased special root length and root nitrogen concentration, but root tissue density and the carbon:nitrogen ratio were reduced. Intriguingly, the synergistic effect resulted in greater trunk girth without sacrificing height, compared to trees receiving CF or BIO alone.Conclusions: The combination of BIO and CF improves root traits and tree growth, suggesting that using bio-organic fertilizer as a supplement to reduce the application rate of chemical fertilizer is beneficial to orchard ecosystems.
Exploring the Role of Asp1116 in Selective Drug Targeting of CREBcAMP- Responsive Element-binding Protein Implicated in Prostate Cancer
Authors: Akinsiku Oluwayimika E. , Soremekun Opeyemi S. , Olotu Fisayo A. , Soliman Mahmoud E.S.
Published: February 2020

Background:

The selective targeting of CREB-cAMP-responsive element-binding
protein (CBP) has recently evolved as a vital therapeutic approach for curtailing its aberrant
upregulation associated with the development of prostate cancer. Inhibition of CBP has been
discovered to be an important therapeutic option in androgen receptor signalling pathway mediated
prostate cancer. Y08197, a novel selective inhibitor of CBP, has shown promising therapeutic
outcome in prostate carcinogenesis over non-selective analogues such as CPI-637.

Methods/Results:

Herein, we used molecular dynamics simulation to gain insights into the
mechanistic and selective targeting of Y08197 at the bromodomain active site. Molecular
Mechanics/ Poisson-Boltzmann Surface Area (MM/PBSA) analysis revealed a similar inhibitory
effect between Y08197 and CPI-637. Furthermore, in exploring the selective affinity of Y08197
towards CBP in combination with Bromodomain and PHD finger-containing protein 1(BRPF1),
our findings highlighted Asp1116 as the ‘culprit’ residue responsible for this selective targeting.
Upon binding, Asp1116 assumed a conformation that altered the architecture of the bromodomain
active site, thereby orienting the helices around the active site in a more compacted position. In
addition to some specific structural perturbations mediated by Asp1116 on the dynamics of CBP,
our study revealed that the strong hydrogen bond interaction (N-H...O) elicited in CBP-Y08197
sequestered Y08197 tightly into the CBP bromodomain active site.

Conclusion:

Conclusively, the inhibition and selective pattern of Y08197 can be replicated in
future structure-based CBP inhibitors and other bromodomain implicated in carcinogenesis.

Published: February 2020

Stem cells are undifferentiated cells and have a great potential in multilineage differentiation. These cells are classified into adult stem cells like Mesenchymal Stem Cells (MSCs) and Embryonic Stem Cells (ESCs). Stem cells also have potential therapeutic utility due to their pluripotency, self-renewal, and differentiation ability. These properties make them a suitable choice for regenerative medicine. Stem cells differentiation toward functional cells is governed by different signaling pathways and transcription factors. Recent studies have demonstrated the key role of microRNAs in the pathogenesis of various diseases, cell cycle regulation, apoptosis, aging, cell fate decisions. Several types of stem cells have different and unique miRNA expression profiles. Our review summarizes novel regulatory roles of miRNAs in the process of stem cell differentiation especially adult stem cells into a variety of functional cells through signaling pathways and transcription factors modulation. Understanding the mechanistic roles of miRNAs might be helpful in elaborating clinical therapies using stem cells and developing novel biomarkers for the early and effective diagnosis of pathologic conditions.

Objective:

This study was conducted to determine the correlation between the occurrence ofStreptococcus mutans(S. mutans) which is considered as the main pathogen responsible for the initiation and development of dental caries with blood groups and Rhesus (Rh) factor that are considered as a genetic predictor of having dental caries among healthy students.

Methods:

Saliva and blood samples were taken from 40 healthy students whose ages were between 19-23 years old in the College of Dentistry/Al-Iraqia University in Baghdad, Iraq. Estimation of the flow rate and pH was done for all the collected saliva samples within 5 min of saliva collection. Then, 100 µL of saliva was cultured on Mitis salivarius bacitracin agar (MSBA) at 37 °C for 48 h. The colonies ofS. mutanswere identified by their morphology and biochemical tests. Later, 1 to 2 drops of blood were taken from each student’s thumb to determine the blood group.

Results:

This study showed there was a greater prevalence ofS. mutansamong students of blood group A in contrast to the blood group O. In addition, Rh+ groups were dominant than Rh- groups among the study samples.

Conclusion:

S. mutanslevels were higher in the blood group A followed by AB, B, O blood groups among the college students studied.

Authors: Shukla Aparna , Kanungo Suvendu
Published: February 2020

Background:

Image analysis plays a vital role in the biometric identification system. To
achieve the effective outcome of any biometric identification system, the inputted biometric image
taken should be of fine quality as it greatly impacts the decision. Image segmentation is a significant
aspect of image analysis that must be carried out for enhancing the quality of an image. It efficiently
differentiates the foreground and background region of the inputted biometric image and
facilitates further image processing simply by providing a segmented binary image which is more
coherent to the system.

Objective:

We present an efficient clustering based image segmentation approach to obtain the quality segmented binary image that further processed to get the quality decision in biometric based identification system.

Method:

A centre of mass based centroid clustering approach for image segmentation has been proposed to perform binarization of an image so as the adequate and operative results can be found.

Result:

The performance of the proposed approach has been applied on different sets of biometric data set having different number of hand images. Resultant this approach provides the sharp and lucid images so that good enough and effective intended results can be obtained.

Conclusion:

The centroid based clustering approach for image segmentation outperform the existing clustering approach. In order to measure the quality of segmented binary image three statistical performance parameters are used: PSNR, SUMD and Time Elapsed (sec).
Retóricas de la distinción en la crónica latinoamericana
Authors: Viu Adagio Julieta
Published: February 2020

Este artículo se propone trazar un mapa de la crónica latinoamericana moderna e iluminar una serie de hitos artísticos y culturales que signaron su historia. Con el objetivo de identificar y periodizar los intereses hegemónicos de los escritores en relación con el campo cultural y las lecturas teóricas generales del arte y la literatura. Estos análisis permitieron identificar el auge del divismo modernista caracterizado, entre otras cuestiones, por la reivindicación de la aristocracia del arte; la celebridad basada en una retórica de la fama; y en oposición a éstos la emergencia de la plebeyez que ubica en el centro de la representación a personajes populares. La originalidad de este trabajo reside en la lectura del campo de la crónica cuya tradición de estudios en general ha avanzado por autores apreciados individualmente. De igual importancia en cuanto a su originalidad es el haber identificado los tópicos descritos, desconsiderados por el campo de la crítica. Abstract: This article aims to draw a map of the modern Latin American chronicle and illuminate a series of artistic and cultural milestones that marked its history.

Effect of Long-Term Electrical Spinal Cord Stimulation on Expression of Non-Reciprocal Inhibition α-Motoneurons of Human Skeletal Muscles
Authors: Roshchina L. V. , Gladchenko D. A. , Pivovarova E. A. , Chelnokov A. A.
Published: February 2020

It is known, transcutaneous electrical spinal cord stimulation (tESCS) in the T11-T12 level of the thoracic vertebrae increases the power capabilities of the leg agonist muscles. One of the inhibition spinal mechanisms that protects skeletal muscles from excessive force is non-reciprocal inhibition. Taking into account the biological role of non-reciprocal inhibition, the aim of the study was to research the effect of long-term tESCS on expression of non-reciprocal inhibition of soleus muscle α-motorneurons in humans at rest and when holding a weak static force. Materials and methods: the study involved 22 healthy male subjects aged 27 to 35 years. Non-reciprocal inhibition of α-motorneurons was recorded during the 20-minute tESCS in the T11-T12 level of the thoracic vertebrae at rest, in combination with arbitrary muscular effort (5% of MVC) and after its impact. Results: TESCS at rest resulted in the weakening of non-reciprocal inhibition within 20 minutes of exposure and 10 minutes after the end of stimulation. TESCS in combination with arbitrary muscular effort in 5% of the MVC increases the activity of non-reciprocal inhibition for 20 minutes of stimulation and 10 minutes after its end. The proposed physiological mechanisms underlying the effect of long-term tESCS on expression of non-reciprocal inhibition are discussed.
An Assessment of Religion, Peace and Conflict in the Post 1991 of Ethiopia
Authors: Antigegn Getahun Kumie
Published: February 2020

Religious violence has become increasingly relevant in political and academic discourses. Because of the revival of religions, the contemporary world cannot be understood without accounting for the role of religion and religious organizations in peace and conflict, including the case of Ethiopia. The purpose of this article is to examine the role of religion in peace and conflict in the post 1991 of Ethiopia. Methodologically, the paper employed qualitative research approach by relying on secondary sources of data. The findings of the research revealed that Ethiopia has many positive assets that have to be exploited fully and critically including the role of the Inter-Religious Council. The religious policies of the present Ethiopian government are remarkably different from any of the previous ones with regard to the measure of religious freedom they provide. Paradoxically, one may wonder why is it at this time, where religious freedom and equality of religion are guaranteed, we are witnessing increased tensions and violent religious conflicts in contemporary Ethiopia. Inter-religious relations in Ethiopia have been peaceful and tolerant for long period. However, the rise of inter-religious conflicts in recent decades is taking place. Generally, in contemporary Ethiopia religion is used both as an instrument for producing conflict in certain circumstances and as a powerful resource for peace and transformation of conflict in the society. On the whole, identifying the role of religion in conflict is a very complex task to accomplish, as there are multiple variables to be well-thought-out.

Published: February 2020

The study of the psycho-emotional features of patients with coronary heart disease (CHD) is important for the development of psychological rehabilitation measures. In particular, it is necessary to take into account the speciﬁcs of the experienced fears and anxiety states which can be manifested in patients after myocardial infarction (MI). Negative psycho-emotional experiences are known to inﬂuence the course and prognosis of the disease. Identiﬁcation of the structure of phobic manifestations, anxiety and personal characteristics of patients is appropriate for optimizing psychodiagnostics and psychocorrection. The present research is aimed at studying the characteristics of phobic manifestations and the structure of anxiety in patients with coronary heart disease (CHD) after myocardial infarction (MI), considering the dominant state, indicators of quality of life and personal characteristics. In the course of the present study 67 patients were surveyed with gender distribution of 12 women (18%) and 55 men (82%): patients of the Almazov National Medical Research Centre of the Ministry of Health of the Russian Federation who had a history of myocardial infarction (up to 1 year) and had undergone myocardial revascularization. The average age of the patients was 58.95 years. Clinical interview and psychological testing (Dominant State Determining Method, Integrative Test of Anxiety, The 36-Item Short Form Health Survey (SF-36), The Big Five Personality Test) were used. In patients with CHD after MI with substantial fears the most frequently detected phobic manifestations are the fear of physical activity and the fears associated with the disease itself. In the group of patients with the presence of phobic manifestations more pronounced indicators of anxiety, lower indicators of quality of life (QoL) and emotional stability in the structure of personal characteristics were noted. When planning psychological rehabilitation for patients with CHD who have undergone MI, it is important to consider the likelihood of anxiety and phobic manifestations.

Authors: Syuib Muhammad
Published: February 2020

Undang-Undang Dasar 1945 mengisyaratkan bahwa setiap warga negara memiliki hak yang sama untuk mencalonkan diri sebagai calon kepala daerah. Isyarat ini tertuang dalam Pasal 28D ayat (3) yang menyebutkan bahwa “Setiap warga negara berhak memperoleh kesempatan yang sama dalam pemerintahan”. Berdasarkan Pasal 123 ayat 3 Undang-Undang Nomor 5 Tahun 2014 tentang Aparatur Sipil Negara menyatakan bahwa  Pegawai ASN dari PNS yang mencalonkan diri atau dicalonkan menjadi gubernur dan wakil gubernur; bupati/walikota dan wakil bupati/wakil walikota wajib menyatakan pengunduran diri secara tertulis sebagai PNS sejak mendaftar sebagai calon. Untuk itu, dibutuhkan penelitian lebih lanjut untuk mengetahui landasan pertimbangan PNS harus mundur jika maju dalam Pilkada. Maka dari itu, penelitian ini bertujuan untuk menemukan dan menjelaskan landasan pertimbangan sehingga PNS harus mundur dari jabatan organiknya jika maju sebagai calon kepala daerah. Metode penelitian yang digunakan adalah yuridis normatif yang menitik beratkan pada penelitian data kepustakaan atau yang disebut data sekunder, serta mengkaji peraturan perundang-undangan berkaitan dengan persyaratan pencalonan bagi PNS yang maju sebagai calon kepala daerah. Hasil penelitian menunjukkan bahwa PNS harus mundur dari jabatan negeri adalah bagian dari ketundukkannya terhadap aturan-aturan yang mengatur birokrasi pemerintahan dan aturan-aturan kepegawaian karena ketika seseorang telah memilih menjadi PNS maka dia telah mengikatkan diri dalam ketentuan-ketentuan yang mengatur dirinya sebagai aparatur negara. Selain itu, agar terhindar dari adanya penyalahgunaan wewenang karena hal itu melanggar hukum.
Biblioteconomia, Ciência e Filosofia: um debate necessário sobre teoria e prática no campo acadêmico-científico
Authors: Salcedo Diego , Cruz Marcílio Bezerra
Published: February 2020

Parte do pressuposto e da observação em sala de aula, nas disciplinas sobre pesquisa, ciência e filosofia ofertadas no Curso de Biblioteconomia da Universidade Federal de Pernambuco, de que boa parte dos estudantes demonstra certa dificuldade ou resistência no modo de entender a relação entre a teoria e a prática no cerne do campo acadêmico-científico. Tem como objetivos propor um debate a respeito das relações teórico-práticas no interior das pesquisas científico-acadêmicas, bem como contribuir com a produção de bibliografia didática para uso dos estudantes. O debate está dividido em três seções: analisa tanto o desenvolvimento histórico do racionalismo e do empirismo, quanto as suas influências na estrutura das pesquisas acadêmicas e científicas; indica como o idealismo alemão (na filosofia) e o positivismo (na ciência) promoveram uma cisão entre a teoria e a prática; e examina essa herança de pensamento bipartido no contexto brasileiro. Pesquisa de caráter exploratória utilizou a metodologia de revisão bibliográfica. Aponta como consideração final que o senso comum tem como herança a opinião, principalmente dos estudantes que ingressam na universidade, de que tanto o fazer científico não possui relação estreita com algumas atividades acadêmicas, quanto que as atividades acadêmico-científicas indicam a polarização entre a teoria e a prática, ambas opiniões inadequadas no cenário da contemporaneidade.

Justifica-se a realização da pesquisa em virtude de ser tema atual e de interesse sempre presente nos campos da Ciência da Informação e da Administração, em especial. Além disso, diferenciar o conhecimento estratégico como elemento fundamental para a geração de estratégias e para a tomada de decisão estratégica é particularmente importante para auxiliar na gestão da informação e do conhecimento nas organizações. A produção de trabalhos sobre conhecimento estratégico vem merecendo maior atenção nos últimos tempos e destaca a preocupação das organizações com a gestão desse ativo intangível, particularmente quanto a uso, impacto, visão, foco, pessoas e estratégia. O estudo do conhecimento estratégico traz a possibilidade da discussão do tema em nível individual (além do organizacional), bem como do aprofundamento da sua diferenciação frente a outros conhecimentos dentro da organização.

Authors: Castro Fabiano Ferreira de , Jesus Ananda Fernanda de
Published: February 2020

O Linked Data foi desenvolvido visando atender ao contexto tecnológico vigente e pode ser aplicado potencialmente ao domínio bibliográfico. Objetivou-se verificar a viabilidade e a relevância de se adequar os dados bibliográficos aos princípios do Linked Data. A coleta de dados baseou-se em uma metodologia de caráter qualiquantitativo, pautado na realização de uma Revisão Sistemática da Literatura. Os dados foram analisados à luz das seguintes categorias: enfoque dos documentos, requisitos necessários para a adequação de dados bibliográficos ao Linked Data, vantagens e desafios relacionados a essa adequação. Como resultados, identificaram-se o Resource Description Framework (RDF) e o Uniform Resource Identifier (URI) como requisitos necessários para prover a adequação de dados bibliográficos ao Linked Data. As principais vantagens identificadas foram a interoperabilidade de dados, melhores resultados de busca, maior visibilidade dos dados das bibliotecas no ambiente Web e promoção de descoberta acidental de recursos. Os principais desafios identificados foram a heterogeneidade dos dados disponibilizados na Web e a conversão dos dados descritos em formato MARC21. Concluiu-se que os dados bibliográficos podem ser adequados ao Linked Data, porém, muitos desafios ainda precisam ser superados para permitir essa realidade.
A transparência ativa das IFES brasileiras que ofertam a graduação em Arquivologia
Authors: Rosa Tatiana Costa , Cabero Maria Manuela Moro
Published: February 2020

Analisa-se os portais eletrônicos de 13 Instituições Federais de Ensino Superior que ofertam o curso de Graduação em Arquivologia, considerando 17 requisitos de transparência informacional ativa, estabelecidos nos artigos 7° e 8° do Decreto n° 7.724/2012 que regulamenta a Lei de Acesso à Informação brasileira. Tais instituições podem contar com cursos de Arquivologia que incidam na implantação da transparência informacional, uma vez que são formadoras de profissionais arquivistas, os quais estão intimamente interligados com a disponibilização do acesso informacional e da transparência pública. Desenvolve-se um estudo de natureza exploratória, quali-quantitativa e comparativa, mediante a identificação e análise dos critérios de transparência ativa. Os resultados demonstram que os cursos de Arquivologia que ofertam componentes curriculares direcionados ao acesso e à transparência fazem parte das IFES que contemplaram totalmente o maior número de requisitos. Ademais, a transparência ativa vem ocorrendo, embora não em sua totalidade.
Memórias e histórias do departamento de bibliotecas escolares e comunitárias de Florianópolis: 1988 a 2018
Authors: Capistrano Tatiana Quadra e Silva , Unglaub Tânia Regina da Rocha
Published: February 2020

A memória está relacionada com a construção de armazenamentos de informações e fatos vivenciados. Entende-se que ela é a matéria prima da história, e é considerada um dos alicerces que dá sentido à vida, a sociedade e a uma instituição. Dentre as classificações de estudos sobre memória há a memória institucional, que tem como objetivo manter viva e pública a trajetória de instituições, por meio de relatos, fotos, documentos e/ou objetos, que de forma organizada e com informações consistentes transmitem a história do local. Com essa concepção, este artigo apresenta a origem e trajetória da atuação do Departamento de Bibliotecas Escolares e Comunitárias (DEBEC) da rede municipal de Florianópolis, que engloba os anos de 1988 a 2018. Esse estudo faz parte de uma pesquisa de mestrado profissional em andamento, vinculada ao Programa de Pós-Graduação em Gestão da Informação da Universidade do Estado de Santa Catarina. Trata-se de uma pesquisa histórica, desenvolvida por estudos bibliográficos, exame a fontes documentais e entrevistas a protagonistas que fizeram parte dessa história. Assim como tece uma colcha de retalhos, essa pesquisa foi construída. Um depoimento aqui e outro documento acolá encontraram e teceram a trajetória histórica dessa instituição. A temática surgiu devido a aproximação da pesquisadora com as atividades e projetos criados e desenvolvidos por esse Departamento junto aos bibliotecários da rede. Os resultados obtidos contribuíram para de suprir a lacuna sobre a memória institucional do Departamento e produzir reflexões sobre a importância desse Departamento para a Rede de Bibliotecas Escolares e Comunitárias de Florianópolis.
O buraco negro criado pelas Tecnologias da Informação e Comunicação
Authors: Carvalho Antonio Aparecido de , Farina Milton Carlos , Carvalho Leonardo Birche de
Published: February 2020

A pesquisa teve o intuito de trazer à tona uma análise crítica acerca da forma de coleta, armazenamento e acesso a dados e informações, anteriormente documentados eram arquivados em meio manual, tais como relatórios, livros dentre outros, já na atualidade a tecnologia de informação e comunicação trouxe a ideia de que as informações devem estar armazenadas em meios digitais, nuvens, pen drives, e-mails e demais hardwares,  contudo surge o seguinte questionamento: “O que nos garante que  no futuro teremos programas, dispositivos e ferramentas compatíveis para acessá-las?” Documentos e informações anteriormente armazenados em fitas cassetes, disquetes ou nas memórias de computadores antigos, por vezes se tornam inacessíveis devido à indisponibilidade de dispositivos devido à obsolescência de equipamentos ou até mesmo das constantes atualizações de softwares. A impossibilidade de acesso às informações arquivadas digitalmente é conhecida como “Buraco Negro Digital”. A pesquisa demonstra que algumas organizações estão antevendo problemas e buscando possíveis soluções para preservação documental e consequentemente da nossa história para as gerações futuras, contudo muito há de ser feito.

Published: February 2020

As florestas ciliares no sul de Santa Catarina têm sofrido recorrentes impactos, principalmente pela introdução de espécies animais e vegetais exóticas, pela pressão agrícola, pelo crescimento das cidades e pela extração do carvão mineral, sendo, no entanto, estruturalmente pouco conhecidas. Este estudo teve como objetivo determinar a estrutura do componente arbóreo em seus distintos estágios sucessionais em 29 fragmentos de Floresta Pluvial subtropical na bacia hidrográfica do rio Urussanga. Em cada fragmento florestal foram alocadas duas parcelas de 10 m × 10 m, perpendiculares à margem do rio, onde foram amostrados os indivíduos arbóreos com diâmetro do caule à altura do peito (DAP) ≥ 5cm. No total foram amostradas 119 espécies arbóreas. Os fragmentos em estágio médio de sucessão apresentaram maior riqueza (n = 86), seguido pelos de estágio avançado (n = 73) e em estágio inicial (n = 59), evidenciando que os fragmentos florestais ao longo da bacia hidrográfica do rio Urussanga se encontram em pleno processo de restauração ambiental.
Ambiência e desenho sonoro no documentário Terras (2009)
Authors: Serafim José Francisco , Salama Martins Raquel
Published: February 2020

Este artigo parte da análise fílmica do documentário Terras (2009), de Maya Da-Rin, para propor uma reflexão acerca do potencial narrativo e estético do som ambiente no cinema. Partimos da hipótese de que há um conjunto de produções no documentário brasileiro contemporâneo que apontam para o mesmo caminho de explorar esse elemento sonoro para além de um acessório figurativo da imagem. Com base nos conceitos de desenho sonoro e hiper-realismo sonoro, ao longo desta análise procuramos compreender os modos pelos quais os ruídos deixam de ser apenas um pano de fundo sônico das imagens e passam a produzir sentidos e sensações.

The multiparameter t’distribution
Authors: Ghorbel Emna , Louati Mahdi
Published: February 2020

This research paper stands for an extension to the multivariate
t?distribution introduced in 1954 by Cornish, Dunnett and Sobel, namely the
multiparameter t?distribution. This distribution is expressed in two
different ways. The first way invests the mixture of a normal vector with a
natural extension to the Wishart distribution, that is the Riesz
distribution on symmetric matrices. The second one rests upon the Cholesky
decomposition of the Riesz matrix. An algorithm for generating this
distribution is investigated using the Riesz distribution arising obtained
through not only the distribution of the empirical normal covariance matrix
for samples with monotone missing data but also through Cholesky
decomposition. In addition, Some fundamentals properties of the
multiparameter t?distribution such as the infinite divisibility are
identified. Besides, the Expectation Maximization algorithm is used to
estimate its parameters. Finally, the performance of these estimators is
assessed by means of the Mean Squared Error between the true and the
estimated parameters.

Underlying Simple Graphs
Authors: Koch Sebastian
Published: February 2020

In this article the notion of the underlying simple graph of a graph (as defined in [8]) is formalized in the Mizar system [5], along with some convenient variants. The property of a graph to be without decorators (as introduced in [7]) is formalized as well to serve as the base of graph enumerations in the future.
