Aplicação de um índice de sustentabilidade ambiental na bacia hidrográfica do Rio do Campo – PR
Authors: Gottstein Pauline , Arantes Eudes José
Published: December 2023

A crescente preocupação em compatibilizar o desenvolvimento econômico, a preservação ambiental e a justiça social, tem fortalecido o paradigma do desenvolvimento sustentável. Diante disso, o presente estudo teve como objetivo aplicar um índice de sustentabilidade ambiental na bacia hidrográfica do Rio do Campo - PR, a fim de subsidiar o planejamento e gestão dos recursos hídricos, empregando técnicas de geoprocessamento. O índice de sustentabilidade (IS) determinado neste estudo é constituído de três fatores, os quais foram calculados para nove sub-bacias e para a bacia do rio do Campo como um todo. Os resultados foram expressos na forma de um número entre zero e um, onde quanto mais próximo da unidade melhor a condição de sustentabilidade da bacia. Assim, a bacia do rio do Campo apresentou nível médio de sustentabilidade com IS de 0,64. Contudo, a obtenção do IS por sub-bacia permitiu a identificação de diversos níveis de sustentabilidade dentro da mesma área de estudo. Portanto, considera-se que o IS possa ser utilizado para um rápido diagnóstico das condições da bacia, sendo aproveitado pelas comunidades locais, instituições públicas e entidades de caráter privado, no suporte ao planejamento e gestão de ações socioeconômicas e ambientais voltadas para a sustentabilidade das sub-bacias analisadas.

Published: December 2023

Este artigo apresenta uma análise comparativa do conforto térmico em três edificações habitacionais construídas com sistemas construtivos distintos: madeira, alvenaria, wood frame. Através de uma análise estatística detalhada e de uma pesquisa de percepção a respeito da sensação térmica dos usuários dos ambientes ao longo das quatro estações do ano, a pesquisa destacou os pontos positivos, negativos e diferenciais das três edificações por meio de um estudo comparativo. As edificações utilizadas como bases para este estudo fazem parte de um stand de venda de uma construtora, as quais no momento da pesquisa eram utilizadas para atividades comerciais, tal como escritório de vendas. A pesquisa traz um apontamento significativo a respeito do sistema construtivo wood frame, o qual ainda é considerado um sistema inovador para países sul-americanos. Os resultados evidenciaram o potencial do sistema construtivo wood frame comrelação ao conforto térmico no clima subtropical predominantemente frio da região de Curitiba.
O processo de raciocínio da TOC e a aplicação da árvore da realidade atual (ARA): o caso dos pregões eletrônicos para aquisição de medicamentos de um Hospital Público Federal
Authors: Ferrando Magnus D'Olanda , Lock Fernando Do Nascimento
Published: December 2023

O trabalho tem por objetivo identificar as restrições da fase interna em processos licitatórios da modalidade de pregão eletrônico, para aquisição medicamentos em um Hospital Público Federal. Trata-se de uma pesquisa exploratória, com abordagem qualitativa na modalidade de um estudo de caso. Para tanto, foram aplicadas entrevistas semiestruturadas com gestores e agentes executores, observação in loco e levantamento de registros dos processos de pregões eletrônicos, por meio da pesquisa documental. Para identificação das restrições adotou-se o Árvore da Realidade Atual, que é uma das ferramentas do Processo de Raciocínio da Teoria das Restrições onde se concluiu que a carência de qualificação e o acúmulo de funções são as restrições da fase interna que geram a maior parte dos sintomas observados na pesquisa. Logo, a gestão dos processos de pregão eletrônico para aquisição de medicamentos demanda atenção especial que deve ser objeto diferenciado de qualificação pelos agentes envolvidos, com a finalidade de reduzir as restrições identificadas, compreender toda a estrutura de compras de medicamentos em um hospital público federal e propor ações que efetivamente possam corrigir ou minimizar os sintomas observados.
Dinâmicas urbanas na configuração das cidades cearenses: análise com base no REGIC 2018
Authors: Rodrigues da Silva Wellington , Nunes de Queiroz Silvana
Published: December 2023

O trabalho busca analisar as dinâmicas urbanas das cidades cearenses com base na classificação hierárquica do estudo das Regiões de Influência das Cidades (REGIC). O Ceará foi escolhido como recorte geográfico por apresentar regiões de influência que acabam configurando os espaços urbanos, inclusive em nível nacional. Para tanto, utilizaram-se dados do estudo do REGIC realizado nos anos de 2007 e 2018, e variáveis referentes as centralidades do ensino superior, diversidade do comércio e serviços, estimativa populacional e econômica das cidades, no intuito de analisar a pertinência dos níveis hierárquicos de cada variável. Com relação as estimativas populacionais, entre o período em estudo, as pequenas e médias cidades passaram a concentrar mais pessoas. A diversidade do comércio e serviços demonstrou que houve maior dinamização na oferta, especialmente nas cidades que sofreram alteração positiva no REGIC, como os casos do Arranjo Populacional (AP) de Juazeiro do Norte, Tianguá, Aracati, Brejo Santo e Horizonte. O processo de interiorização do ensino superior foi importante para que cidades não metropolitanas pudessem ofertar serviços educacionais, tanto público quanto privado, tendo como destaques o AP de Juazeiro do Norte, Brejo Santo, Quixeramobim e Tianguá, cidades que apresentaram alteração no nível hierárquico do REGIC.
Analytical dependence of burnup on enrichment of prospective fuel and parameters of reactors fuel campaign
Authors: Semenov Evgeny V. , Kharitonov Vladimir V.
Published: December 2023

The paper is devoted to the definition of an analytical expression for estimating the burnup depth of nuclear fuel depending on its enrichment level, the periodicity of refueling, thermal stressthermal stress and the duration of the time period between refueling (reactor campaign) in a wide range of changes in key parameters for different types of thermal neutron reactors. The analytical expressions obtained in the work for the burnup depth are compared with numerous neutron physics calculations and experimental data from different authors for uranium fuel enrichment up to 9%. Calculations of the fuel share of the cost of electricity of nuclear power plants with PWR type reactors were performed and its sensitivity to changes in burnup depth and enrichment of fuel, the refueling periodicity, as well as to market prices for natural uranium, conversion, enrichment, fabrication of fuel assemblies and SNF handling were determined.
Radioecological modeling of the 131I activity dynamics in the pasture vegetation of Mazovia in the year of the Chernobyl accident: Reconstruction, verification, reliability assessments
Authors: Vlasov Oleg K. , Zvonova Irina A. , Shchukina Nataliya V. , Chekin Sergey Yu.
Published: December 2023

A radioecological model, which is a system of linear differential equations describing the dynamics of the transport of 137Cs and 131I radionuclides along the food chain after their release into the atmosphere after the Chernobyl accident, was used to reconstruct “instrumental” data of the 131I activities in the grass pastures in the central part of Mazovia. Four atmospheric models were used for the reconstruction: direct calculation, homogeneous cloud – inhomogeneous rainfall, inhomogeneous cloud – homogeneous rainfall, and a model with recalculation of the 137Cs and 131I activities in the atmosphere. The “instrumental” data were reconstructed based on data from direct measurements of the 131I activity in lawn grass. It has been shown that the direct calculation and homogeneous cloud models lead to a better agreement of the calculated and reconstructed “instrumental” data than the inhomogeneous cloud model. The arithmetic mean ratio of the calculated and reconstructed “instrumental” data lie in a range of 0.84 to 0.95 for the direct calculation and homogeneous cloud models, and in a range of 1.7 to 3.0 for the inhomogeneous cloud model. The mean geometric deviation for all models is constant and equal to 1.7. Instrumental and reconstructed “instrumental” data show a significant decrease in the specific activity of 131I in grass due to its wash-off by continuous rainfall, both during rainfall and after most of the deposition takes place. Due to this effect, the coefficient of the 131I retention on grass in the form of the maximum activity ratio to the 137Cs deposition density decreases from 34 to 1.4 m2/kg while it increases from 1 to 29 kBq/m2 as the result of the rainfall growth from 0 to 40 mm.

Published: December 2023

The high-fat (HF) diets can be used to generate a valid rodent model for metabolic syndrome (METS). The aim of this study was to compare three different diets, namely a high-fat, high-carbohydrate diet (HF-HCD), a high-fat lard-based diet (HFD), and a cafeteria diet (CFD), in terms of the ability to induce METS. The next step was to characterize the syndrome according to the biochemical and histopathological changes in the liver and pancreas, and to determine the optimal animal model. As a result, all diets disturbed significantly the serum biochemical parameters. HF-HCD and CFD increased the uric acid levels and reduced the weight gain in comparison with the standard chow diet (SCD) and HFD. The HFD and CFD induced the highest fasting glycemia levels. Although the animals fed with HF-HCD had the lowest body weight, the most serious histopathological changes in the pancreas, hypertension, and oxidative stress were noted in them.
La statue décernée par l’Amphictionie de Delphes à Eumène II en 182 et le pilier dit « d’un empereur romain »
Authors: Gondat Julien
Published: December 2023

L’article propose d’attribuer le pilier dit « d’un empereur romain », érigé à Delphes, au piédestal, jusqu’alors non identifié, de la statue décernée par l’Amphictionie au roi Eumène II, connue par un décret de 182. Son analyse architecturale et sa comparaison avec les autres édifices du même type révèlent des caractères propres aux Attalides ; elles permettent d’établir une chronologie relative et rapprochent le monument de ceux élevés pour Persée. Ces éléments ne permettent plus d’attribuer le pilier à un empereur romain ; en revanche, ils concordent avec les honneurs octroyés à Eumène II dans un moment crucial pour le roi de Pergame.
Réintroduire les émotions pour comprendre ce qui se joue au sein de la relation Business Angel « technophile » vs ingénieurs-entrepreneurs « technologiques »
Authors: Demauras Karine
Published: December 2023

Cet article présente comment les émotions peuvent impacter les relations entre les Business Angels (BA) et les ingénieurs entrepreneurs. Il apporte une nouvelle perspective par l’analyse en binôme, contrairement à la littérature qui les a trop individualisés. Après avoir présenté le profil très singulier du BA «  technophile » , des témoignages au travers de mini-cas illustrent les singularités émotionnelles de mise en œuvre des projets entrepreneuriaux. L’analyse montre que si la formation initiale scientifique et technique favorise l’approche rationnelle du projet technologique, la symbiose du binôme est bousculée par la réalité de la création d’entreprise et le trouble d’une des 4 racines des émotions. Elle propose ensuite des préconisations pratiques d’accompagnement individuel et du projet entrepreneurial, essentielles au bon développement de la relation dans le temps.

La possible légalisation de la GPA amène à s’interroger sur ce qui est impliqué en termes de rapport de l’esprit au corps. Le discours néolibéral, qui est à l’arrière-plan, privilégie l’intérêt d’individus réputés « rationnels ». Mais on peut s’interroger sur cette glorification de l’« esprit » (ou de la volonté) au détriment du corps et de son vécu.

De quel rapport social la domination adulte est-elle la marque : vers l’hypothèse d’un minorat exploité ?
Authors: Dunezat Xavier
Published: December 2023

Nous interrogeons, dans cet article, la domination adulte au prisme des orientations théoriques de la sociologie des rapports sociaux de sexe-classe-race d’inspiration féministe matérialiste. Nous soulignons d’abord que, au sein des travaux sur l’âgisme, la domination adulte et l’oppression des enfants sont sous-traitées, ce qui nous conduit – dans le sillage des travaux plaidant pour une prise en compte du minorat – à axer la focale sur le statut de mineur·e afin de discuter les arguments qui font de l’âge un rapport social d’une autre nature que les autres.
Au nom du soin et de la protection. Les « droits de l’enfant » au prisme de l’institution psychiatrique
Authors: Vernay Olivia
Published: December 2023

Depuis la fin du xx e  siècle et davantage encore au cours de cette dernière décennie, la thématique des droits de l’enfant est omniprésente dans notre société. Le texte de référence en la matière, la Convention internationale des droits de l’enfant de 1989, conçu et appliqué par des adultes, reconnaît ainsi aux jeunes de moins de 18 ans différents droits censés être équivalents. Cependant, parce qu’associés aux devoirs des adultes envers des enfants considéré·es comme vulnérables, il s’avère bien souvent que les droits dits spécifiques (à la protection et aux soins notamment) priment sur les droits civils (d’opinion, d’expression, de liberté de penser), particulièrement lorsque l’opinion des enfants entre en contradiction avec les attentes de la société et la volonté des adultes. En analysant les droits de l’enfant au prisme des hospitalisations « non volontaires » d’adolescent·es en psychiatrie, cet article questionne la domination adulte exercée sur les mineur·es au nom du soin et de la protection, les violences produites par l’institution psychiatrique et la vulnérabilité assignée aux jeunes concerné·es.
L’enseignant spécialisé compris comme sujet chercheur en contexte inclusif
Authors: Dicharry-Pomarez Sandrine , Kohout-Diaz Magdalena
Published: December 2023

L’article présente une recherche qui vise à explorer la définition de l’identité d’un enseignant inclusif par un acte d’engagement de sa parole comme sujet. Il est considéré comme « sujet d’une éthique et non objet d’une science » (Kohout-Diaz, 2018, p. 110). La chercheure elle-même se positionne en tant que « chercheure accompagnatrice » (Beauvais, 2004) impliquée auprès d’enseignants spécialisés en formation, dans l’objectif de comprendre le professionnel de terrain comme chercheur qui agit dans la complexité de la diversité des besoins des élèves. Le sujet est envisagé comme « un acteur compétent » (Guignon, Morissette, 2006) qui mobilise dans son acte de parole ses savoirs d’expérience. La méthode de l’entretien et du questionnaire formatif permet d’en rendre compte. Les résultats permettent de cerner une posture d’enseignant spécialisé qui agit à la manière d’un chercheur sur le terrain.
Visible et invisible. De l’inclusion scolaire à la reconnaissance
Authors: Serir Zakaria , Gremion François
Published: December 2023

Certains dispositifs inclusifs (EASNIE, 2016 ; Gillig, 2016) visent à mettre en place des mesures de compensation pour les élèves en situation de handicap et ceci afin de leur permettre de participer pleinement à l’éducation (Meier-Popa et Ayer, 2020). Cependant, derrière cette démarche, il se pose la question de la reconnaissance de l’enfant, c’est-à-dire reconnaitre sa différence qui fait partie intégrante de son identité plurielle (Sen, 2006) et de sa singularité. La réflexion sur l’inclusion scolaire soulève dès lors des questions philosophiques et morales. Il est essentiel pour les auteurs de remettre en question de manière critique les conséquences d’une visibilisation induite par un enseignement non séparatiste. L’inclusion scolaire suppose-t-elle que les enfants ayant des besoins éducatifs particuliers soient visibles et qu’ils existent sur le chemin de leur reconnaissance potentielle ? Ou l’enseignement non séparatiste ne se réduit-il pas au déplacement physique d’enfants toujours invisibles et donc non reconnus vers un lieu et un espace considérés comme ordinaires ?
Les facteurs de développement et de réussite des partenariats interinstitutionnels :
Authors: Lande Évelyne , Rasolonjatovo Hasina
Published: December 2023

La littérature sur les partenariats institutionnels et sur les partenariats interuniversitaires en particulier, nous indique que la réussite n’est pas systématiquement au rendez-vous. L’objectif de cet article est donc de mettre en évidence les facteurs clés de développement et de réussite de ces types de partenariats en mobilisant la métaphore du couple au titre d’illustration et en prenant le cas de l’IAE de l’université de Poitiers. Les résultats ont montré que pour réussir, une collaboration interuniversitaire ne doit pas seulement être de nature contractuelle, mais doit impérativement intégrer des aspects plus interpersonnels. Il faut également que la confiance et le partage y règnent. Enfin, il est nécessaire pour les parties concernées d’avoir une aptitude à accepter l’évolution et à y faire face. Les résultats ont aussi montré que la création d’un écosystème de connaissance, de recherche, de formation est un élément indispensable au développement des partenariats.

Integrated optimization of planning and operation of a shared automated electric vehicle system considering the trip selection and opportunity cost
Authors: Li Hao , Wang Zhengwu , Chen Shuiwang , Xu Weiyao , Hu Lu , Huang Shuai
Published: December 2023

Shared autonomous electric vehicle systems (SAEVS) combine autonomous driving technology with shared electric vehicle services to provide advantages over traditional shared vehicle systems, including autonomous vehicle relocation and rapid response to user needs. In this study, we seek to enhance the operational efficiency and profitability of SAEVS by considering trip selection and the potential opportunity cost associated with unmet user demands. An integer linear programming (ILP) model is developed using a spatio-temporal state network to optimize the system design planning (e.g., charging facility, vehicle fleet sizing and distribution) and operational decisions (e.g., vehicle operational relocation and trip selection strategy). To handle the computational complexities of this model, we propose a Lagrangian relaxation (LR) algorithm. The performance of the LR algorithm is evaluated through a case study. The results, along with a parameter sensitivity analysis, reveal several key findings: (ⅰ) Allocating vehicles to stations with concentrated early peak demand, distributing charging facilities to stations with high total demand throughout the day and implementing vehicle relocation after the early demand peak can mitigate uneven vehicle distribution; (ⅱ) Implementing trip selection enhances SAEVS profitability; (ⅲ) Increasing opportunity cost meets user demands but at the expense of reduced profit; (ⅳ) It is recommended that SAEVS be equipped with charging facilities of suitable charging power based on operational conditions.
MTTLm6A: A multi-task transfer learning approach for base-resolution mRNA m6A site prediction based on an improved transformer
Authors: Wang Honglei , Zeng Wenliang , Huang Xiaoling , Liu Zhaoyang , Sun Yanjing , Zhang Lin
Published: December 2023

N6-methyladenosine (m6A) is a crucial RNA modification involved in various biological activities. Computational methods have been developed for the detection of m6A sites in Saccharomyces cerevisiae at base-resolution due to their cost-effectiveness and efficiency. However, the generalization of these methods has been hindered by limited base-resolution datasets. Additionally, RMBase contains a vast number of low-resolution m6A sites for Saccharomyces cerevisiae, and base-resolution sites are often inferred from these low-resolution results through post-calibration. We propose MTTLm6A, a multi-task transfer learning approach for base-resolution mRNA m6A site prediction based on an improved transformer. First, the RNA sequences are encoded by using one-hot encoding. Then, we construct a multi-task model that combines a convolutional neural network with a multi-head-attention deep framework. This model not only detects low-resolution m6A sites, it also assigns reasonable probabilities to the predicted sites. Finally, we employ transfer learning to predict base-resolution m6A sites based on the low-resolution m6A sites. Experimental results on Saccharomyces cerevisiae m6A and Homo sapiens m1A data demonstrate that MTTLm6A respectively achieved area under the receiver operating characteristic (AUROC) values of 77.13% and 92.9%, outperforming the state-of-the-art models. At the same time, it shows that the model has strong generalization ability. To enhance user convenience, we have made a user-friendly web server for MTTLm6A publicly available at http://47.242.23.141/MTTLm6A/index.php.
Spillover effects: A challenging public interest to measure
Authors: Kotíková Sylvie
Published: December 2023

Spillover effects represent a difficult-to-measure externality resulting from the localization of foreign capital in the host economy. Despite their character of externality, spillover effects represent a public interest. The governments of many transitional economies spend financial resources in the form of investment incentives to support economic growth and spillover effects from the inflow of foreign direct investment (FDI). However, there is still no established methodology for regularly measuring spillover effects. This article tries to fill this gap. It aims to measure the spillover effects of FDI localization in the host business environment with the possibility of identifying differences in their size and development on the level of regions within the host economy — in the case of the Czech Republic. Based on shift-share analyses, an indicator quantifying the size of the technology gap at the regional level has been constructed. The benchmarking method illustrates the absorption capacity of the business environment in an interregional comparison reflecting the strong and weak sides of the regions in terms of absorbing the benefits of locating multinational corporations in their territories. The spillover effect was evaluated based on five criteria: gross value added (GVA), technology gap level, investment in research and development (R&D), share of people with secondary and higher education and inflow of FDI. The higher the value of the constructed Spillover index achieved in the region, the higher the positive effect of FDI on economic development. The spillover effects were evaluated within the years 2002–2021 and assessed the impact of 211 FDI on the economic development of five regions of the Czech Republic. Calculations showed that the strength and magnitude of spillover effects fully reflect the weaknesses of peripheral regions. The methodology offers policymakers a tool (indicator) for improving the targeting of institutional support in relation to economic growth and the development of the business environment.

The study evaluates the variability of water balance using different indices for the period 1961–2018 in Cotnari and surroundings, in the middle part of the Moldavian Plateau (MP), Romania. With the aid of statistical analysis and remote sensing, we discovered that the Cotnari's SPEI (Standardized Precipitation and Evapotranspiration Index) variability is characterized by severe values that alternate between significant excess and significant deficits. According to SPEI, between 57.2 and 61.4% of the months were near normal in terms of water balance. There were between 19.3 and 25.1% months with water excess and between 17.1 and 20.8% with water deficit. The links between NDVI and SPEI become stronger as SPEI reaches extreme values (above 1.5 units or below −1.5 units). The water balance indicates a decrease in available water resources.

With the emergence of deep learning, Convolutional Neural Network (CNN) models have been proposed to advance the progress of various applications, including face recognition, object detection, pattern recognition, and number plate recognition. The utilization of CNNs in these areas has considerably improved security and surveillance capabilities by providing automated recognition solutions, such as traffic surveillance, access control devices, biometric security systems, and attendance systems. However, there is still room for improvement in this field. This paper discusses several classic CNN models, such as LeNet-5, AlexNet, VGGNet, GoogLeNet, and ResNet, as well as lightweight models for mobile-based applications, such as MobileNet, ShuffleNet, and EfficientNet. Additionally, deep CNN-based face recognition models, such as DeepFace, DeepID, FaceNet, and SphereFace, are explored, along with their architectural characteristics, advantages, disadvantages, and recognition accuracy. The results indicate that many scholars are researching lightweight face recognition, but applying it to mobile devices is impractical due to high computational costs. Furthermore, noise label learning is not robust in actual scenarios, and unlabeled face learning is expensive in manual labeling. Finally, this paper concludes with a discussion of the current problems faced by face recognition technology and its potential future directions for development.

Environmental pollution caused by human activities is a global concern, and recycling is an effective strategy to reduce waste and minimize its negative impact on the environment, as these pollutants can have detrimental impact on ecosystems, human health, and the quality of life in general. Recycling avoids the accumulation of waste in landfills, which can contaminate soil, water, and air as well as reducing the production of new products. The objective of this work is to implement a mobile application to improve waste management by recycling companies. The Mobile-D methodology was used for the development of the project because it focuses on optimizing the efficiency and performance of mobile applications since it allows working in 5 phases which are: Exploration, Initialization, Production, Stabilization and Testing. In the first indicator (KPI-1), an improvement in customer retention was observed, with an increase of 114.29% in positive responses in the post-test. In the second indicator (KPI-2), there was a 39.92% decrease in response time, indicating a faster response in the collection service. In the third indicator (KPI-3), a significant increase of 86.86% in the volume of waste for recycling was observed. The results showed improvements in all indicators, indicating a positive impact of the implementation of the mobile application on waste management by the companies in the sector.

Integrating technology into learning has become a pivotal necessity in the digital age. This underscores the imperative for educators, serving as facilitators, to organize and implement digital technology within instructional processes adeptly. Central to this application is educators’ perceptions of the utilization of mobile digital textbooks. Crucially, this study, rooted in a qualitative research design, sought to elucidate teachers’ perceptions regarding the employment of the Mobile Digital Textbook, integrated with a STEM approach, to enhance students’ spatial thinking and Higher-Order Thinking Skills (HOTS). Data collection was meticulously executed through semi-structured interviews involving fifteen geography educators from eight East Java, Indonesia, secondary institutions. With the aid of NVIVO software, the data were systematically organized and categorized based on pre-established criteria. The findings revealed a predominantly positive perception among the fifteen participants towards using the Mobile Digital Textbook with the STEM approach in fostering students’ spatial thinking and HOTS. The implications of this research underscore the significance of continuous training and support for educators in assimilating digital technology, particularly mobile digital textbooks, to elevate instructional quality and cultivate students’ advanced cognitive abilities.

Published: December 2023

In response to university-wide budget cuts, librarians at Georgia Southern University were charged with evaluating the librariesâ€™ collections in preparation to make $300,000 in cuts for 2022. Past initiatives to assess the librariesâ€™ collections have had mixed results and few true successes. The library faculty have struggled to present information about resources in a comprehensive yet easy to understand way that encourages participation by departmental faculty. In light of previous experiences, the library faculty decided to scrap the old way of collecting feedback and instead develop a new process to present data in a clear and precise manner. Throughout this process, the library faculty strove to balance usage data and other metrics with faculty input to make renewal decisions. This presentation showcased tools and templates that Georgia Southern librarians developed during this assessment and highlighted what we learned.

Authors: Keller Shannon , Wood Amy
Published: December 2023

The Research Collections and Preservation Consortium (ReCAP) partners contracted the Center for Research Libraries (CRL) to do a volume level analysis of their combined print serial collections. This paper focuses on the decision to use the OCLC number as the primary match point and the starting point for the collection analysis, challenges encountered due to inconsistent OCLC number use across collections, the way those challenges informed the overall project, and the method CRL created to find OCLC numbers for records without them. Final results of the volume-level analysis, ongoing work to integrate Harvardâ€™s serials into the analysis, and the effects of ReCAP partnersâ€™ collaborative collection development initiatives are included.
Intersections of Open Access and Information Privilege in Higher Education and Beyond
Authors: Harrington Caitlin , Scott Rachel E.
Published: December 2023

Despite its capacity to reach readers irrespective of affiliation or geographic location, conversations about Open Access (OA) frequently center academic stakeholders in high-income countries. This presentation will examine opportunities for technical services librarians to explore with students some of the inequities of the scholarly communications landscape, including various approaches to and aspects of OA, and to consider the disparate levels of access available to individuals based on institutional affiliation. Because higher education settings afford students a high degree of information privilege, academic librarians face the challenge of teaching students to appreciate the value of information, acknowledge barriers to it, and identify and evaluate the freely available resources and content to which they will have access post-graduation. Although technical services and scholarly communication librarians tend to have fewer teaching responsibilities than those working in public services, our experiences with collection development, licensing, and resource description provide insights to share with students regarding information value and privilege. A case study on student projects which included the editing of Wikipedia entries highlights tensions between institutional privilege and open resources. Teaching students about the costs, processes, and value of information production empowers them to understand their privilege and responsibilities.

Governança de Redes de Franquias em Mercados Emergentes: Um Estudo da Presença de Franquias Multi-Unidades em Redes Brasileiras
Authors: Jose Silva Bitti Eugenio , Medeiros Magnani Vinicius , Miranda Mendonça Paulo Sergio
Published: December 2023

Na discussão em torno de governança de redes de franquias, a proporção de lojas próprias e franqueadas (mix contratual) é um tema recorrente. No caso do presente estudo, uma terceira possibilidade em termos deste mix é abordada: o franqueado multi-unidades (franqueados que operam duas ou mais unidades de uma mesma rede). A literatura no tema tem, de forma quase unânime, indicado benefícios decorrentes da presença de MUFs (multi-unit franchisees). O estudo desenvolve e testa um modelo teórico relacionando custos horizontais de agência e ativos intangíveis (locais de sistêmicos) à opção de franqueadores pelo uso mais intenso de franquias multi-unidades em comparação a franquias tradicionais (single-unit franchisees) ou lojas próprias. São aplicados procedimentos econométricos sobre uma amostra com 202 redes referente ao ano de 2018. Os resultados indicam que a concentração de lojas em mercados contíguos, a uniformidade e a importância da manutenção da proposta de valor da rede estão associadas a uma maior proporção de lojas MUF. Espera-se contribuir para a literatura de governança e controle de redes de franquias ao abordar um fenômeno que não é tão novo, mas ainda é muito pouco conhecido em termos de estruturação destas redes.

Published: December 2023

Comfort, protection and similar characteristics, which have become imperative for the production of sportswear materials, constantly encourage the textile industry and researchers to search for new innovative solutions. Recently, there are three main areas that scientists focus on - comfort, functionality and aesthetic appeal of sportswear. For the purpose of this research, a set of novel yarns is selected and used to design knitted materials intended for the production of functional sportswear. In this paper the changes in the material properties due to the use of different novel yarn compositions are observed. Regarding the material properties, the mass loss due to the material abrasion, and water vapour transfer rate were measured and analysed. The results of the investigation indicated that the material with the lowest mass, thickness and densities (both horizontal and vertical) exhibit the lowest decrease of mass due to abrasion. The highest decrease of mass is confirmed for the most compact material composed of viscose, polyester standard and elastane. It was further confirmed that the highest water vapour transfer rate exhibits the material that has the lowest density.
