Prediction of Student’s Academic Performance Using Linear Regression
Authors: Bum S , Iorliam I B , Okube E O , Iorliam A
Published: July 2020

Recently, there has been a tremendous increase of failure rate in higher institutions. Often times, students of tertiary institutions drop-out of school or end up with certain classes of degrees that are far lesser than their ideal intellectual capabilities. As fresh students enroll into higher institutions, some may not even know what a class of degree is, and the level of work that is likely to place them in a particular class of degree. Predicting their academic performance in this wise becomes necessary to ascertain the future of their performances in order to make informed decisions. Traditionally, we find out “who failed in an examination” or who “passed in an examination”. However, predictions usually finds out who is likely to fail and who is likely to pass an examination and to what extent the failure or pass could be. Hence, predictions serve as counseling tool for the students to either improve their work rate or maintain their rate to achieve higher performance in subsequent examinations. In this paper, we predicted the academic performance of Benue State University students using linear regression. Linear regression assumes a linear relationship between the dependent variables (x) and an independent variable (y) such that the slope (predicted) can be specifically calculated from a computational linear combination of the variables x and y. Our proposed system correctly predicted the performance of mathematics/computer science students of the Benue State University with an accuracy of up to 100%.

Published: July 2020

The production of ethanol from cassava flour using Zymomonas mobilis a gram negative bacterium was conducted at 30oC, 33oC, 35oC and 37oC. The fermentation reaction was also carried out at different substrate concentrations; 5% W/V, 7% W/V and 10% W/V. The microorganism Zymomonas mobilis was detected in palm wine, isolated and identified. It was found to be gram negative, oxidase negative, catalase positive, anaerobic and plump rods with an unusual width. Results obtained from the simultaneous saccharification and fermentation reactions carried out with Zymomonas mobilis showed that maximum theoretical ethanol yield of 63% was obtained for 7% W/V cassava flour at 35oC. This was followed by a theoretical yield of 56.23 and 54.12 for 5% W/V and 10% W/V cassava flour, respectively. Fermentations at 30oC and 33 oC gave similar results with 7% W/V cassava producing higher ethanol yield when compared to 5% W/V and 10% W/V. Fermentation reactions at 37oC gave the lowest ethanol yields. The optimum pH for the simultaneous saccharification and fermentation of cassava was found to be pH of 6.

The emergence of various forest resources problem in Indonesia, pragmatically could not be launched from the processes that occured in higher education. As a manifestation of development communication events, pedagogical communication that occurs in forestry education was important to be observed. This paper aims to explain the facts that occured in the teaching and learning process at the selected Faculty of Forestry, including to explain epistemology that form those facts. The research paradigm is a critical paradigm in qualitative research. Samples were taken purposively by conducting classroom observations, in-depth interviews with students and lecturer, desk study and conducting Focus Group Discussion. The results of this research show that there are facts which lead to the ineffectiveness of pedagogical communication. There are at least 8 issues that became the impetus for the occurrence of such ineffectiveness. The situation has made the message construction thus was not carried but only administrative issues answered in ongoing pedagogical communication. It makes a silent culture increasingly wide spread and inquiries that build students awareness of being not able to grow.

Characterisation of biofilm hotspots at a can filling line for beer
Authors: Wagner Eva M. , Thalguter Sarah , Rychli Kathrin , Wagner Martin
Published: July 2020

Biofilms are thought to play a serious role in the food processing environment. Direct contact with or detachment of microorganisms of biofilms could lead to product contamination resulting in diminished shelf life of the product. Packaging and filling are essential key steps for product safety, as any contamination within this step will directly impact the shelf life and safety of the product. For bottled and canned beverages filling lines are used for filling huge amounts of product in a standardised manner. Most parts of these lines are cleaned and disinfected automatically during cleaning in place (CIP) procedures. The design of these filling lines is of great importance, as accessibility and materials are crucial regarding the success of automatic cleaning and disinfection programs. Some companies implemented additional manual cleaning strategies for the complete removal of potential problem-causing sites. In the brewery setting the term biofilm is manifested since the 90s. However, until now all studies focus only on the presence of microorganisms, neglecting the presence of matrix components, which constitutes an essential component of a biofilm.  

Within this study a filling line for cans, capable of filling 60000 cans per hour (volume 0.5 l), was investigated regarding critical sites for biofilm formation. The filling line is used primarily for beer, but mixed beer drinks are also filled. We sampled 23 sites using a scraper-flocked-swab method at two time points. The first sampling was done during operation and the second sampling was conducted one month later after the automated cleaning and disinfection procedure. The samples were characterised regarding their microbial load (qPCR for 16S rRNA and 18S rRNA genes) and the presence of biofilm matrix (phenol-sulfuric assay for carbohydrates, precipitation and SDS-PAGE with subsequent silver staining for proteins and precipitation and spectrophotometric quantitative measurements for extracellular DNA).

During operation, we could identify three sites harbouring a biofilm by applying the definition of presence of microorganisms and at least two matrix components. Furthermore, there were seven sites harbouring microorganisms and one matrix component. After cleaning and disinfection no biofilm could be detected. At one site, microorganisms and one matrix component could be detected. The drastic reduction of biofilm positive sites indicates the successful removal of biofilms by the cleaning and disinfection process.

The design of future filling plants should emphasise on the principles of hygienic design, as this can help to prevent biofilm formation and targeted removal of biofilms during cleaning and disinfection. The here identified biofilm hotspots indicate potential problem-causing sites and weak-points in the design of the filling line.
Sediment size on talus slopes correlates with fracture spacing on bedrock cliffs: Implications for predicting initial sediment size distributions on hillslopes
Authors: Verdian Joseph P. , Sklar Leonard S. , Riebe Clifford S. , Moore Jeffrey R.
Published: July 2020

Abstract. The detachment of rock fragments from fractured bedrock on hillslopes creates sediment with an initial size distribution that sets the upper limits on particle size for all subsequent stages in the life of sediment in landscapes. We hypothesize that the initial size distribution should depend on the size distribution of latent sediment (i.e., blocks defined by through-going fractures) and weathering of sediment before or during detachment (e.g., disintegration along crystal grain boundaries). However, the initial size distribution is difficult to measure, because the interface across which sediment is produced is often shielded from view by overlying soil. Here we overcome this limitation by comparing fracture spacings measured from exposed bedrock on cliff faces with particle size distributions in adjacent talus deposits at 15 talus-cliff pairs spanning a wide range of climates and lithologies in California. Median fracture spacing and particle size vary by more than tenfold and correlate strongly with lithology. Fracture spacing and talus size distributions are also closely correlated in central tendency, spread, and shape, with b-axis diameters showing the closest correspondence with fracture spacing at most sites. This suggests that weathering has not modified latent sediment either before or during detachment from the cliff face. In addition, talus has not undergone much weathering after deposition and is slightly coarser than the latent sizes, suggesting that it contains some fractures inherited from bedrock. We introduce a new conceptual framework for understanding the relative importance of latent size and weathering in setting initial sediment size distributions in mountain landscapes. In this framework, hillslopes exist on a spectrum defined by the ratio of two characteristic timescales: the residence time in saprolite and weathered bedrock, and the time required to detach a particle of a characteristic size. At one end of the spectrum, where weathering residence times are negligible, the latent size distribution can be used to predict the initial size distribution. At the other end of the spectrum, where weathering residence times are long, the latent size distribution can be erased by weathering in the critical zone.
Engaging children in geosciences through storytelling and creative dance

Published: July 2020

Abstract. Natural sciences have traditionally been disseminated in outreach
activities as formal, one-way presentations. Nevertheless, innovative
strategies are being increasingly developed using arts, gaming, and sketching, amongst others. This work aimed at testing an alternative and innovative way
to engage non-expert audiences in ocean and coastal geology through a
combination of scientific concept explanations and creative dancing. An
informal education activity focusing on ocean dynamics was designed for
10-year-old students. It combines coastal science concepts (wind, waves,
currents, and sand), storytelling techniques (narrative arc), and creative
dance techniques (movement, imaginative play, and sensory engagement). A
sequence of six exercises was proposed, starting with the generation of
offshore ocean waves and ending with sediment transport on the beach during
storm/fair-weather conditions. Scientific concepts were then translated into
structured creative movements, within imaginary scenarios, and accompanied
by sounds or music. The activity was performed six times with a total of 112
students. It was an inclusive activity given that all students in the class
participated, including children with several mild types of cognitive and
neurological impairment. The science and art activity aroused emotions of
enjoyment and pleasure and allowed for effective communication between
scientists and school community. Moreover, the results provide evidence of the
activity's effectiveness in engaging children and developing their willingness
to further participate in similar activities.
Exploring the Parameters Space of the Regional Climate Model
COSMO-CLM 5.0 for the CORDEX Central Asia Domain
Authors: Russo Emmanuele , Sørland Silje Lund , Kirchner Ingo , Schaap Martijn , Raible Christoph C. , Cubasch Ulrich
Published: July 2020

Abstract. The parameter uncertainty of a climate model represents the spectrum of the results obtained by perturbing its empirical and unconfined parameters used to represent sub-grid scale processes. In order to assess a model reliability and to better understand its limitations and sensitivity to different physical processes, the spread of model parameters needs to be carefully investigated. This is particularly true for Regional Climate Models (RCMs), whose performances are domain-dependent. In this study, the parameter space of the RCM COSMO-CLM is investigated for the CORDEX Central Asia domain, using a Perturbed Physics Ensemble (PPE) obtained by performing 1-year long simulations with different parameter values. The main goal is to characterize the parameter uncertainty of the model, and to determine the most sensitive parameters for the region. Moreover, the presented experiments are used to study the effect of several parameters on the simulation of selected variables for sub-regions characterized by different climate conditions, assessing by which degree it is possible to improve model performances by properly selecting parameter inputs in each case. Finally, the paper explores the model parameter sensitivity over different domains, tackling the question of transferability of an RCM model setup to different regions of study. Results show that only a sub-set of model parameters present relevant changes in model performances for different parameter values. Importantly, for almost all parameter inputs, the model shows an opposite behavior among different clusters and regions. This indicates that conducting a calibration of the model against observations to determine optimal parameter values for the Central Asia domain is particularly challenging: in this case, the use of objective calibration methods is highly necessary. Finally, the sensitivity of the model to parameters perturbation for Central Asia is different than the one observed for Europe, suggesting that an RCM should be re-tuned, and its parameter uncertainty properly investigated, when setting up model-experiments to different domains of study.
How does daily groundwater table drawdown affect the diel rhythm
of hyporheic exchange?

Published: July 2020

Abstract. Groundwater table dynamics extensively modify the volume of the hyporheic zone and the rate of hyporheic exchange processes. Understanding the effects of daily groundwater table fluctuations on the tightly coupled flow and heat transport within hyporheic zones is crucial for water resources management. With this aim in mind, a physically based model is used to explore hyporheic responses to varying groundwater table fluctuation scenarios. Effects of different timing and amplitude of groundwater table daily drawdowns under gaining and losing conditions are explored in hyporheic zones influenced by natural flood events and diel river temperature fluctuations. We find that both diel river temperature fluctuations and daily groundwater table drawdowns play important roles in determining the spatiotemporal variability of hyporheic exchange rates, temperature of exfiltrating hyporheic fluxes, mean residence times, and hyporheic denitrification potentials. Groundwater table dynamics present substantially distinct impacts on hyporheic exchange under gaining or losing conditions. The timing of groundwater withdrawal has a direct influence on hyporheic exchange rates and hyporheic buffering capacity on thermal disturbances. Consequently, the selection of aquifer pumping regimes has significant impacts on the dispersal of pollutants in the aquifer and thermal heterogeneity in the sediment.
The era of Infiltration
Authors: Beven Keith
Published: July 2020

Abstract. Inspired by a quotation from Howard Cook in 1946, this paper traces the evolution of the infiltration theory of runoff from the work of Robert Horton and LeRoy Sherman in the 1930s to the early digital computer models of the 1970s and 1980s. The reasons for the popularity of the infiltration theory are considered, as well as its impact on the way in which hydrological responses were perceived by several generations of hydrologists. Reconsideration of the perceptual model for many catchments, partly as a result of the greater appreciation of the contribution of subsurface flows to the hydrograph indicated by tracer studies, suggests a more precise utilisation of hydrological terms and, in particular, that the use of runoff and surface runoff should be avoided.
An integrated modeling framework for coevolution and feedback loops of nexus across economy, ecology and food systems based on the sustainable development of water resources

Published: July 2020

Abstract. Sustainable development in water resources is becoming a hot topic in recent years. The world is facing the disequilibrium between the availability of resources and the increase in population with fast-growing economies and social development. This study proposes a new methodological framework of sustainable development of water resources based on the response linkages and feedback loops of economy-ecology-food (EEF) nexus. It provides a new way to identify the interconnection and coevolution process between these EEF. The multi-objective model and system dynamic (SD) model were coupled to characterize the interconnections between processes and their dynamic responses to a set of scenarios. The combination of decomposition-coordination method (DC) and dynamic programming was used to find the optimal scenario based on each component of the EEF nexus. The Upper reach of Guijiang River Basin (UGRB) was presented as a case study. Results showed that the coupled multi-objective model and SD model presented in this study are able to characterize the interactions and feedback between EEF systems adequately. Most importantly, the rapid growth rate of socio-economic indexes will drive the awareness of river ecology and showed a higher sensitivity under different decision preferences. The results provided in this study can provide baseline information for stakeholders and policymakers in the field of water management for a better understanding of the interactions across systems.
Spatial cellular robot in orbital truss collision-free path planning

Published: July 2020

Abstract. Aiming at the problem of moving path planning of a
cellular robot on trusses in space station, a triangular prism truss is
taken as the research object, and an optimized ant colony algorithm
incorporating a gravitational search algorithm is proposed. The innovative
use of the hierarchical search strategy which limits the exploration area,
the use of gravity search algorithm to get the optimal solution of truss
nodes, and further transform it into the initial value of pheromone in ant
colony algorithm, can effectively prevent the algorithm from falling into
the local optimal solution in the early stage, and make the optimization
algorithm have a faster convergence speed. This paper proposes a heuristic
function including the angle between the targets, which can effectively
avoid blind search in the early stage and improve the ability of path
search. The simulation results show that the path and planning time of the
cellular robot can be effectively reduced when choosing truss path.
Resilience issues and challenges into built environments: a review
Authors: Heinzlef Charlotte , Barocca Bruno , Leone Mattia , Glade Thomas , Serre Damien
Published: July 2020

Abstract. This paper proposes a review of existing strategies and tools aiming at facilitating the operationalization of the concept of resilience into built environments. In a context of climate change, increased risks in urban areas and growing uncertainties, urban managers are forced to innovate in order to design appropriate risk management strategies. Among these strategies, making cities resilient has become an imperative. This injunction to innovation fits perfectly with the urban, economic, political, social and ecological complexity of the contemporary world. As a result, the concept of resilience is integrated into the issues of urban sprawl and the associated risks. However, despite this theoretical and conceptual adequacy, resilience remains complex to integrate into the practices of urban planners and territorial actors. Its multitude of definitions and approaches has contributed to its abstraction and lack of operationalization. This review highlights the multitude of approaches and methodologies to address the bias of the lack of integration of the concept of resilience in risk management. The limit is the multiplication of these strategies which lead to conceptual vagueness and a lack of tangible application at the level of local actors. The challenge would then be to design a toolbox to concentrate the various existing tools, conceptual models and decision support systems in order to facilitate the autonomy and responsibility of local stakeholders in integrating the concept of resilience into risk management strategies.
Extension and inversion of salt-bearing rift systems
Authors: Dooley Tim P. , Hudec Michael R.
Published: July 2020

Abstract. We used physical models to investigate the structural evolution of segmented extensional rifts containing syn-rift evaporites and their subsequent
inversion. An early stage of extension generated structural topography consisting of a series of en-échelon graben. Our salt analog filled these
graben and the surroundings before continued extension and, finally, inversion. During post-salt extension, deformation in the subsalt section remained focused on the graben-bounding fault systems, whereas deformation in
suprasalt sediments was mostly detached, forming a sigmoidal extensional minibasin system across the original segmented graben array. Little brittle
deformation was observed in the post-salt section. Sedimentary loading from the minibasins drove salt up onto the footwalls of the subsalt faults,
forming diapirs and salt-ridge networks on the intra-rift high blocks. Salt remobilization and expulsion from beneath the extensional minibasins was
enhanced along and up the major relay or transfer zones that separated the original sub-salt grabens, forming major diapirs in these locations. Inversion of this salt-bearing rift system produced strongly decoupled shortening belts in basement and suprasalt sequences. Suprasalt deformation
geometries and orientations are strongly controlled by the salt diapir and ridge network produced during extension and subsequent
downbuilding. Thrusts are typically localized at minibasin margins where the overburden was thinnest, and salt had risen diapirically on the horst
blocks. In the subsalt section, shortening strongly inverted sub-salt grabens, which uplifted the suprasalt minibasins. New pop-up structures also
formed in the subsalt section. Primary welds formed as suprasalt minibasins touched down onto inverted graben. Model geometries compare favorably to
natural examples such as those in the Moroccan High Atlas.

El papel de la tauroflamencología en el universo mishimiano: España y su tradición cultural como ejemplo de resistencia a la homogeneidad occidental
Authors: Ferreiro Posse Dámaso
Published: July 2020

De entre los numerosos países que contribuyeron a la creación tan única del universo de Mishima, España es uno de los que, a pesar de la impronta que dejó en el escritor, menos investigación existe. La relación de Mishima con nuestro país está llena de altibajos, sinsabores y frustraciones. Sin embargo, y a pesar de ello, el tema de lo español mantiene una presencia inamovible a lo largo de su vida, desde su primera visita a Madrid en 1958 hasta el año de su fatal suicidio en 1970. En el presente trabajo analizaremos de forma pormenorizada el papel de lo español en Mishima, representado básicamente bajo la apariencia del flamenco y la tauromaquia, para, con posterioridad, ver la dimensión cultural que el escritor le confiere en relación con lo japonés y lo occidental. Para ello recurriremos a la presentación de diversos textos en traducción, tanto escritos del propio Mishima como entrevistas realizadas al escritor y allegados, todo ello hilvanado a través de tres importantes figuras que, en sus respectivos campos, condicionaron y forjaron el conocimiento que Mishima obtuvo de España, a saber, Antonio el Bailarín, Katori Kiyoko y Luis Díez del Corral.
Childhood, Education and Digital Media Mediation Strategies
Authors: Limone Pierpaolo , Simone Maria Grazia
Published: July 2020

The paper aims to contribute to developing some educational mediation strategies, useful for those who educate in the family and at school, to support children in their first experiences with digital media and the net.Digital technologies are already present in the child's living environments and, just like them, are characterized by a very rapid development. The task of those who do research and those who educate is to know the styles of use, the experiences, the learning, the exploratory maneuvers of the world that very young children perform thanks to digital technology. It should also be considered that, at times, they may be a few clicks away from content and images unsuitable for their age.The paper, through the Systematic Review approach, reviews the most recent scientific literature on the subject and analyzes the results of some important international research projects on the subject.The intent of the work, obviously, is not to provide exhaustive answers, always valid criteria and easy generalizations.With regard to the relationship between childhood and digital media, the paper outlines shared tracks of educational work in the life contexts of the little ones (especially in the family and at school) and reasons to promote further, future investigations in this area.

Authors: Ololade Awotile Adenike , Odogun Loto Adolphus , Adetokunbo Adenuga-Taiwo Olugbenga
Published: July 2020

Aims: To find the correlation between arbitrary surface intercondylar distance on one hand and freeway space, rest vertical dimension, occlusal vertical dimension on the other hand. Methods: A cross sectional study of randomly selected individuals between 18–56 years old, in a tertiary hospital in Ikeja from September- October 2017. Participants were examined and measurements, arbitrary surface intercondylar distance, rest vertical dimension,and occlusal vertical dimension were taken. Data collected were subjected to statistical analysis using SPSS version 20. Level of significance was set at p≤0.05. Results: Of the 48 participants involved in this study, 50% were males. Majority (47.9%) were between 26–35 years old with a mean age of 31 years. Participants in age group 18–25 years and ≥36 years had similar freeway space (FWS) which were 3.43±1.01 mm and 3.45±0.82 mm respectively while 26–35 years old had 3.13±0.87 mm. Mean FWS was 3.29 mm. There was no significant statistical difference in FWS based on gender and age. Spearmans correlation coefficient (R2) analysis revealed a positive correlation of intercondylar distance with freeway space, rest vertical dimension and occlusal vertical dimension. Regression equations were formulated and utilized to calculate concerned parameters. Conclusion: There is correlation between inter condylar distance on one hand and freeway space, rest vertical dimension and occlusal vertical dimension on the other hand. Therefore a regression equation becomes a simple and rapid method of calculating each parameter.

A descriptive study on the perception of health care workers to dental treatment at a tertiary hospital in Lagos, Nigeria
Authors: Afolabi Oyapero , VO Ogunbanjo
Published: July 2020

Aims: Many oral diseases have a strong connection with systemic conditions while effective delivery of health care often requires the combined efforts of all health professionals. Due to the problems of access to dental care, patients may consult other primary health care providers for their oral health needs. This study was undertaken to assess the oral health knowledge, attitude and practices among various health professionals working in Lagos State University Teaching Hospital, (LASUTH). Methods: This cross-sectional study was conducted at the LASUTH Ikeja, Lagos, Nigeria. A stratified probability sampling method was used to categorize the different health professionals in LASUTH and about 20% of the health workers in each category were enlisted using the nominal roll as a sampling frame. A total of 148 questionnaires were administered during the study on subjects who met the inclusion criteria and gave their informed consent. Results: Females and younger respondents were more likely to visit the dentist than males for routine dental check-up even though the association was not significant. The oral health knowledge and attitude among the various health professionals surveyed in LASUTH was found to be inadequate even though Medical doctors had the overall best responses. There was a significant difference between the attitude of the Medical Doctors and other health professionals on questions about extractions (p = 0.024); dental treatments (p = 0.008); dental fillings (p = 0.000); artificial teeth (p = 0.013); bleeding gums (p = 0.002) and replacement of lost teeth (p = 0.004). Conclusion: All health professionals can promote oral health by disseminating accurate oral health messages, being appropriate role models by paying attention to their own oral health, encouraging appropriate dental visits and participating in oral health promotion within their scope of duties. It is also recommended that dental items feature more frequently in hospital ground rounds and clinical meetings of to address this deficit.
Beyond Cultural and Structural Explanations of Regional Underdevelopment: Identity and Dispossession in Appalachia
Authors: Peine Emelie K. , Azano Amy Price , Schafft Kai A.
Published: July 2020

This article brings together education, rural sociology, and political economic perspectives to examine the role of Appalachia in ongoing conversations about civic polity and dynamics of social, economic, and spatial exclusions. First, we explore how the imaginaries of the Appalachian region (and American rurality more generally) reflect the marginalization of those spaces in the context of a deepening rural-urban divide where both are framed as “other”—the former as a socially, culturally, and economically marginal space, with the latter as a realm of the liberal and cosmopolitan elite. We discuss how social and political phenomena are embedded in historical material relations, and how patterns of economic accumulation and inequality reinforce and are reinforced by relations of power. Last, we consider how enduring narratives become fixed in terms of polarization and “identities of dispossession.” We conclude with recommendations for effective strategies to resist these polarized and rigid conceptions by exploring critical pedagogies that invite opportunities to engage in social action that serve to sustain health, economy, and education in Appalachia, and within rural America more broadly.

Posto isso, busca-se explicitar discussões sobre a classificação de documentos de arquivo, seus objetivos e métodos, além de analisar os referidos instrumentos segundo seus elementos de elaboração, correlacionando-os a algumas questões suscitadas no debate atual sobre classificação em arquivos. Metodologia: Para alcançar tais objetivos, valemo-nos de uma revisão e sistematização de literatura nacional e internacional em perspectiva histórica, que abrangeu o período de 1912 até 2018. Resultados: Os resultados sugerem uma histórica percepção da necessidade de reformulação metodológica para a construção de instrumentos de classificação com ênfase na identificação do contexto de produção dos documentos de arquivo. Conclusões: Foi possível concluir que, apesar desta percepção, a efetiva difusão de metodologias de classificação adequadas para os documentos de arquivo, incluindo o Brasil, vai de encontro a um processo histórico não só de aderência, mas, sobretudo de institucionalização da classificação baseada em assuntos.

Authors: Silva Manoela Ferreira da , Evangelista Isadora Victorino , Guimarães José Augusto Chaves
Published: July 2020

Introdução: O periódico Knowledge Organization constitui hoje um dos principais veículos de comunicação científica no que diz respeito a questões de Organização do Conhecimento (OC). Objetivos: Dessa forma, considerou-se pertinente analisar como se apresenta o contexto brasileiro nessas comunicações, verificando quais são os autores e instituições mais produtivas, além de frequência de publicações, coautorias nacionais e colaborações com o exterior. Metodologia: Por meio da análise dos números publicados no período de 2001-2018, foi possível identificar uma forte presença de artigos de autoria brasileira, com um total de 51 produções. Resultados: Percebeu-se uma comunidade liderada pelos professores José Augusto Chaves Guimarães, Daniel Martínez-Ávila, Fábio de Assis Pinho e Renato Rocha de Souza, responsáveis por 28% de todas as publicações nesse período. Como instituições mais produtivas, destacam-se a Universidade Estadual Paulista – UNESP e a Universidade Federal de Minas Gerais – UFMG, instituições essas que possuíam ao menos um autor afiliado em metade das incidências institucionais. Percebe-se ainda, um forte crescimento no número de artigos nos anos mais recentes, em especial no ano de 2012 e 2014 em diante, responsáveis por quase 85% do total de publicações brasileiras na revista. Em relação às coautorias nacionais, pode-se perceber um forte grupo preocupado com aspectos éticos e sociais da organização do conhecimento, estudos em linguagens documentárias, aspectos relativos à recuperação informacional, ontologias, web semântica, dentre outros. A respeito das coautorias internacionais, salientam-se grupos de interesses temáticos, como dimensões éticas e sociais, aspectos bibliométricos, interlocução com as ciências exatas e tecnologias, dentre outros. Conclusões: A liderança do grupo de autores confirma que a revista é aberta a temas como os aspectos éticos e sociais da OC, além das perspectivas tecnológicas no contexto desse domínio. Além disso, uma forte incidência de artigos filiados entre UNESP e UFMG revelou a especificidade e a tradição de pesquisa dessas duas universidades nas temáticas ligadas à organização do conhecimento.Descritores: Análise de Domínio.

Sacrifício ritual nas religiões afro-brasileiras: reflexões sobre patrimonialização, memória e anarquivamento
Authors: Britto Clovis Carvalho , Lima Kellen Josephine Muniz de
Published: July 2020

Introdução: Este artigo investiga como o sacrifício ritual de animais constitui um lugar de memória das religiões afro-brasileiras e as tensões que surgem no campo das políticas do patrimônio. Objetivo: Como desdobramento da problemática, tenta compreender as ressonâncias envolvidas nesse universo simbólico e a teia de elementos que parece sustentar a estratégia de esquecimento das políticas culturais em relação a esse saber-fazer tradicional. Metodologia: Partindo de uma breve análise do processo de registro do ofício das baianas de acarajé, é traçado um comparativo a fim de tentar compreender os elementos que interferem, direta ou indiretamente, na eleição do que é digno de ser rememorado e ocupar o lugar de patrimônio cultural que, em última escala, representa a própria identidade nacional. Resultados: Argumenta que embora o sacrifício ritual seja um lugar de memória das religiões afro-brasileiras, o esvaziamento da sua importância enquanto bem cultural e saber tradicional está diretamente relacionado a ressonância externa negativa dessa prática, consequência do que Yvonne Maggie chamou de “medo do feitiço”, que povoa o imaginário popular e acompanha as religiões afro-brasileiras ainda nos dias atuais. Conclusões: Evidencia o modo como as tensões contribuem para a instituição de “memórias anarquivadas” no campo das políticas patrimoniais brasileiras e as profícuas intersecções entre a ciência da informação e o campo do patrimônio cultural.

Avaliação do desempenho de um software de sumarização automática de textos
Authors: Tabosa Hamilton Rodrigues , Souza Osvaldo De , Cândido José Carlos Dos Santos , Melo Ana Cristina Azevedo Ursulino , Reis Keila Giullianna Braga
Published: July 2020

Desde 2014 desenvolvemos uma pesquisa com o intuito de produzir um software (protótipo) que seria capaz de elaborar resumos automáticos de textos baseado em técnicas de Processamento de Linguagem Natural e estatísticas de frequência de palavras. Os primeiros testes empíricos da ferramenta geraram resultados que indicaram uma significativa redução da dimensionalidade dos textos, com considerável preservação do seu valor semântico. Neste artigo, apresentamos os resultados da continuidade do nosso trabalho investigative, a partir de uma avaliação humana da qualidade desses resumos a partir da realização de testes cegos. Um grupo de três bibliotecárias recebeu um bloco misto e não identificado de resumos - produzidos por humanos e os resumos automáticos feitos pelo software - e procedeu a uma avaliação, segundo os critérios de corretude gramatical, preservação das ideias centrais, coerência e legibilidade, extensão do resumo, se houve paráfrase ou cópia de fragmentos e, se houve introdução de ideias não contidas no texto original. Os resultados mostraram que em quatro, dos cinco critérios de avaliação adotados, houve equivalência qualitativa entre os resumos produzidos por humanos e os produzidos pelo software, o que parece representar um relativo sucesso, uma vez que o prototipo poderia substituir uma pessoa na atividade de resumir textos sem deixar a desejar, a não ser no quinto creitério de avaliação, referente à dimensão do resumo, em que o texto produzido pelo software foi apontado como extenso além do necessário.
O campo da gestão do conhecimento a partir de Bibliometrias
Authors: Elias Maria Ligia Ganacim Granado Rodrigues , Machado Hilka Pelizza Vier
Published: July 2020

Introdução: A Gestão do Conhecimento é um campo interdisciplinar, em decorrência disso, diversos estudos bibliométricos sobre o campo foram publicados, procurando identificar sua abrangência e contornos. Objetivo: Mapear estudos bibliométricos em Gestão do conhecimento, a fim de compreender as fronteiras do campo de estudo, bem como as interfaces com outras áreas. Metodologia: Qualitativa, constituindo-se em uma análise sistemática de estudos bibliométricos sobre gestão do conhecimento entre os anos de 2008 e 2018. Resultados: Os estudos bibliométricos demonstraram que o campo surgiu por volta dos anos 1970 e se consolidou a partir de algumas obras seminais. Ao longo da década de 1990 diversas áreas contribuíram com a abordagem de temáticas que foram incorporadas aos estudos de GC. A partir dos anos 2000 o número de publicações expandiu consideravelmente, tornando o campo multifacetado e desenvolvendo-se em duas vertentes, uma com publicações científicas em diversos Journals e outra em Conferências. Conclusões: O campo da GC apresenta-se como um campo amplo de estudos, com a contribuição de seguintes áreas: Ciência da Computação, Administração/Gestão/Organizações; Economia; Ciência da Informação/Sistemas de Informação; Comunicação; Ciência da Computação, Inteligência Artificial e Biblioteconomia. Há pouca convergência entre as áreas que contribuem para a construção do campo, tanto em termos de autores, como em publicações.
