Authors: Arvola Mattias , Fuchs Inger Edforss , Nyman Ingemar , Szczepanski Anders
Published: June 2021

This paper describes a research project that explored the use of mobile augmented reality combined with outdoor education in a Swedish primary school. Special attention was paid to mobile augmented reality (AR). Project documentation and communication were reviewed, three iterations
of design and usability evaluations of the Minnesmark mobile AR platform was made. Observations and interviews were held with teachers and students. The results describe early experiments, and both the opportunities and challenges that faced the participating teachers. The opportunities included
connecting the outdoor learning environment and the indoor learning environment, directing the students' focus, posing questions and affording actions, rendering symbols and timelines visible, providing a point of entry to the context and the narrative, and facilitating conceptualization.
Challenges concerned how to make pedagogical use of the landscape, producing or choosing content, structuring processes, setting up student groups, and aligning activities and content with learning objectives. It is concluded that the teachers and the students used the mobile augmented reality
to make places in the local environment, outside the classroom, the starting point to increase the authenticity of the teaching.
Smart Playgrounds? Using Smart and Interactive Technologies to Combat Playground Underutilization
Authors: Loukaitou-Sideris Anastasia
Published: June 2021

As settings planned and designed with children in mind, playgrounds have a lot to offer to children's physical, social and educational development. However, US playgrounds are often underutilized by middle-school children, as they become upstaged by electronic and computer games. This
article explores the reasons for playground underutilization in the US through a historic overview of playground development and a review of literature sources that discuss the causes and consequences of playground utilization. It also draws from an empirical study of the author, who surveyed
897 middle-school children and 348 parents in twelve middle schools in Los Angeles to examine their feelings toward playgrounds and find out why they do not visit playgrounds more often. The survey found that many children found the playgrounds unexciting and wished for a different and more
interactive setting. In response to this sentiment, the last part of the article examines the concepts of 'smart park' and 'interactive playground' and discusses opportunities that smart and interactive technologies present for developing twenty-first century playgrounds.

SPACE-TEMPORAL BIOGEOCHEMISTRY OF THE LITTER IN A NATURAL FOREST ENVIRONMENT IN THE CENTRAL AMAZON. This research was aimed to evaluate the concentration of 15 chemical elements as a reference base for the quality of the litter in a forest in the central region of the Amazon. The sampling of the litter was performed monthly in two topographic positions for one year. For the quantification of the elements, digestion by nitroperchloric solution and reading by ICP OES were performed. The mean of macronutrient contents in the litter in decreasing order were Ca>K>Mg>Na. For micronutrients, the order was Al>Mn>Fe>Sr>Zn>Cu>Ba>Cr>Ni>Co>Cd for the Plateau and Al>Mn>Fe Sr>Zn>Cu>Ba>Cr>Ni>Cd>Co for the Baixio. Among the fractions, calcium had its highest concentration in the woody material, potassium in the reproductive material, while magnesium, sodium, and aluminum showed higher concentrations in the leaf fraction. Also, it was observed that the return of the elements to the soil by litter was greater in the dry period of the region, due to the greater fall in plant material. Calcium differed significantly within the same area, obtaining the highest concentrations compared to the other elements, while aluminum and zinc differed significantly between the areas studied, with a higher return for both elements on the Plateau.
CARTESIAN AXIS AND PLANE CONVENTIONS IN Cnv SYMMETRY GROUPS
Authors: Dias Lucas , Faria Roberto
Published: June 2021

In this work, we call the attention to the ambiguity found in the literature when labeling vibrations and molecular orbitals as B1 and B2 for molecules belonging to the C2v point group as, for example, the water molecule. A survey of several books and some articles shows that this ambiguity comes from a long time ago and persists today, being a source of misunderstanding and a waste of time for students and teachers. It means that, in the case of the point groups Cnv, Dn, and Dnh (n = 2, 4, 6), it is very important to draw students’ attention to this ambiguity that exists in the literature. It is unfortunate that the recommendation made by Mulliken, more than sixty years ago, to always place the water molecule in the yz plane, has not been followed.

Published: June 2021

The apple (Malus domestica Borkh.) is one of the major fruit tree crops, but it hasn’t been well-studied as a breeding object for molecular investigations. It is important to develop reliable and rapid methods that allow the preparation of plant material for future research. We introduce a quick and simple method for isolating high-quality RNA from lipid-rich apple seeds (M. domestica cv. Golden Delicious). Our method does not employ highly toxic reagents, because we exclude phenol, 2-mercaptoethanol and others. The chemical composition of the extraction buffer is simple and has a minimum level of toxicity. We showed that, in chaotropic conditions (i.e., with lithium chloride-urea), silica (SiO2) can bind with the lipids and RNA will remain in the solution. The extracted RNA was of high quality and we successfully used it for synthesizing cDNA and RT-PCR. The protocol developed by us can be useful for researchers working with RNA extraction from plant seeds.
Heterogeneity of the barrier properties of the colon in rat

Published: June 2021

The incidence of colorectal cancer in different parts of the large intestine is not the same, as tumors more often appear in the distal part of the colon compared to the proximal one. The purpose of this study was to investigate heterogeneity of the barrier properties of the colon and clarify the effects of Prostaglandin E2 and interleukin-1beta on its different parts. An in-depth analysis of short circuit current, transepithelial electrical resistance and paracellular permeability for sodium fluorescein in Ussing chambers showed that the proximal part of the colon was less permeable compared to the distal one and the substances had different effects on the parameters of permeability in different parts of the colon. We suppose that heterogeneity of the barrier properties of the colon and various effects of their regulation by local molecular agents may determine different incidence of pathologies in the colon.

Published: June 2021

This study assessed the features of the course of acute coronary syndrome in patients with diabetic neuropathy. Additionally, the role of antihyperglycaemic therapy as a cardio protection factor in this syndrome was determined by analysing the available literature data and clinical guidelines. Various antihyperglycaemic drug groups demonstrate possible molecular mechanisms of protection against ischemic cardiomyocytes. Cardiovascular disease treatment for patients with type 2 diabetes mellitus is rapidly developing. However, many aspects, including the exact mechanisms of the cardio protective action of antihyperglycaemic drugs, the presence of an additional positive effect of antihyperglycaemic drugs for patients with other diseases (e.g. kidney disease and chronic heart failure), and possible primary prevention of cardiovascular events in patients with type 2 diabetes, remain unclear.Received 11 September 2020.

Published: June 2021

Aim. To assess the immediate and long-term results of surgical treatment of patients with primary cardiac sarcomas.Methods. In the period from 2013 to 2020, five patients (two men and three women) of different age groups (from 10 to 54 years old) with primary cardiac sarcomas various localisations had been operated at our hospital. In all the patients, the operation was performed from the median sternotomy with cardiopulmonary bypass, normothermia and crystalloid cardioplegia.Results. The average age of the patients was 32 ± 12 years. Two patients had leiomyosarcoma (of right atrium and pulmonary artery), two had angiosarcoma of the right atrium and one was diagnosed with pleomorphic left atrial sarcoma. Only in two patients, the lesion was limited to one chamber; in other cases, the tumour exhibited aggressive infiltrative growth and invasion into the inferior vena cava, myocardium of the left ventricle, contralateral cardiac chambers, pericardium and parietal pleura. Three patients underwent radical surgery with R0 resection, two others underwent cytoreductive surgery with R2 resection owing to the prevalence of the process and the technical impossibility of radical resection. We did not record any in-hospital mortality. Postoperative chemotherapy was administered to four patients. At follow up, (median 18.8 ± 11.7 month), one patient was alive (follow-up 35 months) and was undergoing chemotherapy owing to local recurrence of the disease. One patient with pulmonary leiomyosarcoma underwent re-operation because of local recurrence 1 year after the primary surgery. All the patients died because of disease progression. The average postoperative survival duration in those who died was 14.8 ± 8.1 month.Conclusion. Despite effective early results, long-term survival and tumour-free course were disappointing owing to the initial prevalence of the disease course, the complexity of surgical procedures and the impossibility of radical resection in two cases. However, a multimodality treatment of this pathology, including radical surgical resection of the tumour (R0) along with the modern neoadjuvant and adjuvant chemotherapy, and in some cases, radiotherapy, can improve the survival duration.

Contamination in newly hatched larvae of the mangrove crab Ucides cordatus and a new perspective about trace elements transport
Authors: Almeida Eduardo , Kütter Vinícius , Silva-Filho Emmanoel
Published: June 2021

Mangroves are relevant ecosystems due to their ecological role, economic use, and social importance. One of the most abundant and important species in Brazilian mangroves is the exploited crab Ucides cordatus. This study focuses on this species and the aim was to evaluate the concentration of trace elements in the hepatopancreas of ovigerous females, eggs (pre-hatching and hatching stages), and for the first time, in newly hatched larvae. Ovigerous females were captured in two Southeastern Brazil mangroves (Guanabara Bay and Paraíba do Sul River’s secondary estuary) and spawning was held in spawning tanks, in the laboratory. Some females were not taken to the tanks, but they were frozen right after collection. There was no significant difference in trace element concentration between these females and those kept in the spawning tanks. Both essential and non-essential trace elements were detected in newly hatched larvae. Comparing with the adult female, the elements Zn, Cu, and Mn showed the highest concentrations in larvae and eggs. Vanadium, Cr, and Mn concentrations were significantly higher in hatching eggs than observed in newly hatched larvae, indicating the retention of elements in the eggshell. Considering the V (0.17 - 1.17 μg.g−1 dry weight), Cu (14.1 - 41.1 μg.g−1 dry weight), and Zn (235.4 - 263.9 μg.g−1 dry weight) concentrations in newly hatched larvae, with the same order of magnitude observed in suspended particulate matter (SPM) and sediments in suspension, the planktonic larval dispersion could result in the transport of elements beyond the mangrove, and their introduction in coastal waters.
Syndecan-1 (CD138) as a Pathogenesis Factor and Therapeutic Target in Breast Cancer
Authors: Sheta Mona , Götte Martin
Published: June 2021

The successive stages of breast cancer growth and dissemination depend on
cell-autonomous factors and the communication between tumor cells and their surrounding
cellular and extracellular matrix microenvironment. The cell surface heparan sulfate
proteoglycan Syndecan-1 is dysregulated both in tumor cells and cells of the breast tumor
stroma, indicating a potential role in the pathogenesis of this most frequent malignancy
in women. Indeed, Syndecan-1 interacts with numerous ligands and receptors relevant
to tumor progression, affecting processes as diverse as cancer stem cell function, cell proliferation,
apoptosis, cell adhesion, migration and invasion, tumor angiogenesis, and
leukocyte function in the tumor stroma. The present review summarizes the current understanding
of breast carcinogenesis in correlation with their Syndecan-1 expression, involved
mechanisms, and proposed therapeutic strategies against Syndecan-1-related malignancy.

Published: June 2021

:

The role of gut microbiota in health and diseases has been receiving increased attention
recently. Emerging evidence from previous studies on gut-microbiota-brain axis highlighted the importance
of gut microbiota in neurological disorders. Multiple sclerosis (MS) is a chronic, inflammatory,
demyelinating disease of the central nervous system (CNS) resulting from T-cell-driven,
myelin-directed autoimmunity. The dysbiosis of gut microbiota in MS patients has been reported in
published research studies, indicating that gut microbiota plays an important role in the pathogenesis
of MS. Gut microbiota have also been reported to influence the initiation of disease and severity of
experimental autoimmune encephalomyelitis, which is the animal model of MS. However, the underlying
mechanisms of gut microbiota involvement in the pathogenesis of MS remain unclear.
Therefore, in this review, we summerized the potential mechanisms for gut microbiota involvement
in the pathogenesis of MS, including increasing the permeability of the intestinal barrier, initiating
an autoimmune response, disrupting the blood-brain barrier integrity, and contributing to chronic
inflammation. The possibility for gut microbiota as a target for MS therapy has also been discussed.
This review provides new insight into understanding the role of gut microbiota in neurological and
inflammatory diseases.
Benchmark Test Artifacts for Selective Laser Melting - A Critical Review
Authors: Li Weishi , Wang Kuanting , Fang Shiaofen
Published: June 2021

Background:

Selective laser melting is a best-established additive manufacturing technology
for high-quality metal part manufacturing. However, the technology is yet to be accepted
widely, especially in critical applications, due to the absence of a thorough understanding of the
technology although several benchmark test artifacts have been developed to characterize the performance
of selective laser melting machines.

Objective:

The objective of this paper is to inspire new designs of benchmark test artifacts to better
understand the selective laser melting process, and to promote the acceptance of the selective laser
melting technology.

Method:

The existing benchmark test artifacts for selective laser melting are analyzed comparatively,
and the design guidelines are discussed.

Results:

The modular approach should still be adopted in designing new benchmark test artifacts in
the future, and task-specific test artifacts may also need to be considered furtherly to validate machine
performance for critical applications. The inclusion of the design model in the manufactured
artifact, instead of the conformance to the design specifications, should be evaluated after the artifact
is measured for the applications requiring high-dimensional accuracy and high surface quality.

Conclusion:

The benchmark test artifact for selective laser melting is still under development, and
a breakthrough of the measuring technology for internal and/or inaccessible features will be beneficial
for understanding the technology.
Janelas Sonoras em Tempos de Pandemia
Authors: Herschmann Micael , Trotta Felipe
Published: June 2021

As reflexões desenvolvidas neste artigo tomam como referência não só parte da literatura especializada que analisou a trajetória de algumas sociedades em tempos de pandemia e foi produzida no quadro dos estudos de som, como também o material audiovisual e narrativas levantadas durante uma pesquisa exploratória realizada na mídia tradicional e nas redes sociais da internet sobre o comportamento e reações dos atores durante as quarentenas da covid-19 que ocorreram em 2020 e 2021 em diversas localidades do globo (com destaque não só para o contexto do Brasil e dos Estudos Unidos da América, como também dos países do continente europeu). Salienta-se que se procurou analisar aqui o duplo fluxo de aproximações e afastamentos entre os atores que — privados em grande medida de sua dinâmica de interações coletivas e cotidianas nas cidades (por conta das medidas sanitárias de distanciamento social recomendadas pelas autoridades durante a pandemia) — encontraram em algumas experiências sonoras de solidariedade e de protesto (que ecoaram nos territórios) alternativas para a concretização de intercâmbios socioculturais relevantes. Assim, os atores produziram alianças e tensões peculiares e relevantes nesse contexto, as quais possibilitam que se repense — especialmente da perspectiva dos estudos de som e música — não só as dinâmicas sociopolíticas das experiências acústicas que foram geradas em várias localidades, como também os limites e a porosidade das fronteiras tradicionais entre as esferas do público e do privado.
Cidade e Performatividade: Rupturas Normativas no Espaço Público Informal — Um Estudo de Caso na Cidade do Recife, Brasil
Authors: Dias Lígia , Leite Julieta
Published: June 2021

A partir do questionamento da ideia de uma cidade hegemônica e com estruturas totalizantes, este artigo toma os corpos no espaço urbano como um modo de discutir essas estruturas normativas e, por isso, procura investigar como pensar a cidade para as diversas performatividades, ao levar em consideração os corpos além dos determinados normativos. Para tanto, são utilizados como fios condutores de interpretação e construção da investigação os conceitos de performatividade da filósofa Judith Butler (1990/2020) e os de micropolítica e macropolítica dos filósofos Gilles Deleuze e Félix Guattari (1980/1996), através dos quais se chegou ao entendimento da segmentação do fazer cotidiano. Esses segmentos podem ser caracterizados como linear (os processos históricos), circular (as ocupações do território) e binário (as dualidades sociais). O processo de aplicação em campo dos conceitos estudados foi realizado no Brasil, na cidade do Recife, e a área escolhida foi o entorno do Mercado de São José, localizado no centro histórico, onde existiu, até ao ano de 2019, uma intensa atividade de comércio informal. A investigação estruturou-se em interpretar como se conformam algumas das segmentaridades sociais desse espaço, com o objetivo de caracterizar as relações de apropriação espacial pelos corpos performativos. Diante disso, chegou-se como resultado à enunciação de um conceito para caracterizar a relação entre os corpos e a área observada: os espaços performativos disruptivos. Dessa maneira, este trabalho busca contribuir para a prática do urbanismo, ao propor um olhar mais inclusivo sobre a cidade.
Espaço Inventário, Espaço Inventado
Authors: Pessoa Frederico Augusto Vianna de Assis
Published: June 2021

Este artigo aborda a experiência de construção de territórios de escuta na cidade de Belmonte (Brasil), e discute como a escuta pode ser uma forma de conhecimento do mundo que parte do sensorial e nele mergulha intensamente, para trazer à tona insights que podem nortear compreensões sobre um objeto em diversos aspectos, no caso da cidade, desde sua estrutura urbana até as relações entre pessoas que a habitam. O texto propõe um ensaio em que os diários de viagem dialogam com a abertura para as sensações provocadas pelas paisagens sonoras e suas características reticulares onde o afeto, a convivência, as diferenças, as relações entre seres humanos e não-humanos, as geografias do poder econômico, as diferentes subjetividades, e a multiplicidade que caracteriza uma cidade se manifestam. O texto parte do princípio de que escutar é estar atento ao movimento dinâmico do mundo e à efemeridade dos acontecimentos e entrelaçamentos que nele ocorrem para traduzir o que nos afeta em palavras. Embora se centre em uma abordagem pela escuta, o ensaio reflete sobre a impossibilidade de separação entre os sentidos na percepção e sua atuação contínua nas relações seres humanos–mundo, constituindo não só subjetividades e idiossincrasias individuais, mas também perspectivas compartilháveis sobre o ser e estar no espaço comum.
Corpos Dissonantes e as Lutas Pelo Espaço Urbano: Narrativas em Documentários Internacionais Sobre o Rio de Janeiro
Authors: Gotardo Ana Teresa , Freitas Ricardo Ferreira
Published: June 2021

Um dos imaginários mais sólidos do Brasil diz respeito à perfeição física, representada atualmente na forma dos corpos femininos cisgênero, brancos, magros, que ocupam as praias da zona sul do Rio de Janeiro e assumida como atributo da marca Rio na construção da “cidade olímpica”. Este artigo busca compreender, por meio de uma análise crítica de quatro documentários internacionais de televisão produzidos e exibidos por televisões estrangeiras durante o chamado “período Olímpico”, como os corpos dissonantes a esses imaginários disputam espaços, o direito à cidade e a narrar-se por meio de rompimentos com a marca oficial. Apesar da diversidade cotidiana dos corpos dissonantes, três ganham espaço na mídia internacional: mulheres trans e travestis, analisadas em Gaycation: Brazil de Page e Daniel (2016) e Rio 50 Degrees — Carry on Carioca de Temple (2014); corpos negros e pobres invisibilizados no cotidiano urbano, em Copacabana Palace de Waldron (2014) e pessoas com deficiência que lutam pelo direito à inclusão e à mobilidade em A Bumpy Road to Rio de Fox (2015). Ainda que as representações desses corpos sejam pequenas em relação à ratificação dos imaginários já sólidos dos corpos perfeitos, sua abordagem contribui para dar visibilidade a sujeitos invisibilizados pelo processo de city branding, promovendo um importante questionamento em relação ao achatamento de sujeitos e subjetividades que a estratégia de construção da marca acaba por impor, além de mostrar outras possibilidades de existência, pontos de conflito diversos e de disputas pelo espaço urbano.

Published: June 2021

BACKGROUND

Screen ASSIST is a cessation trial offered to current smokers at the point of lung cancer screening. Because of the unique position of promoting a prevention behavior (smoking cessation) within the context of a detection behavior (lung cancer screening), this study employed prospect theory to design and formatively evaluate a targeted recruitment video prior to trial launch.

OBJECTIVE

The aim of this study was to identify which message frames were most effective at promoting intent to participate in a smoking cessation study.

METHODS

Participants were recruited from a proprietary opt-in online panel company and randomized to a 2 (benefits of quitting vs risks of continuing to smoke at the time of lung screening; BvR) × 2 (gains of participating vs losses of not participating in a cessation study; GvL) message design experiment (N=314). The primary outcome was self-assessed intent to participate in a smoking cessation study. Message effectiveness and lung cancer risk perception measures were also collected. Analysis of variance examined the main effect of the 2 message factors and a least absolute shrinkage and selection operator (LASSO) approach identified predictors of intent to participate in a multivariable model. A mediation analysis was conducted to determine the direct and indirect effects of message factors on intent to participate in a cessation study.

RESULTS

A total of 296 participants completed the intervention. There were no significant differences in intent to participate in a smoking cessation study between message frames (P=.12 and P=.61). In the multivariable model, quit importance (P<.001), perceived message relevance (P<.001), and affective risk response (ie, worry about developing lung cancer; P<.001) were significant predictors of intent to participate. The benefits of quitting frame significantly increased affective risk response (Meanbenefits 2.60 vs Meanrisk 2.40; P=.03), which mediated the relationship between message frame and intent to participate (b=0.24; 95% CI 0.01-0.47; P=.03).

CONCLUSIONS

This study provides theoretical and practical guidance on how to design and evaluate proactive recruitment messages for a cessation trial. Based on our findings, we conclude that heavy smokers are more responsive to recruitment messages that frame the benefits of quitting as it increased affective risk response, which predicted greater intention to participate in a smoking cessation study.
Usability Evaluation of an Offline Electronic Data Capture App in a Prospective Multicenter Dementia Registry (digiDEM Bayern): Mixed Method Study (Preprint)
Authors: Reichold Michael , Heß Miriam , Kolominsky-Rabas Peter , Gräßel Elmar , Prokosch Hans-Ulrich
Published: June 2021

BACKGROUND

Digital registries have been shown to provide an efficient way of gaining a better understanding of the clinical complexity and long-term progression of diseases. The paperless method of electronic data capture (EDC) during a patient interview saves both time and resources. In the prospective multicenter project “Digital Dementia Registry Bavaria (digiDEM Bayern),” interviews are also performed on site in rural areas with unreliable internet connectivity. It must be ensured that EDC can still be performed in such a context and that there is no need to fall back on paper-based questionnaires. In addition to a web-based data collection solution, the EDC system REDCap (Research Electronic Data Capture) offers the option to collect data offline via an app and to synchronize it afterward.

OBJECTIVE

The aim of this study was to evaluate the usability of the REDCap app as an offline EDC option for a lay user group and to examine the necessary technology acceptance of using mobile devices for data collection. The feasibility of the app-based offline data collection in the digiDEM Bayern dementia registry project was then evaluated before going live.

METHODS

An exploratory mixed method design was employed in the form of an on-site usability test with the “Thinking Aloud” method combined with an online questionnaire including the System Usability Scale (SUS). The acceptance of mobile devices for data collection was surveyed based on five categories of the technology acceptance model.

RESULTS

Using the “Thinking Aloud” method, usability issues were identified and solutions were accordingly derived. Evaluation of the REDCap app resulted in a SUS score of 74, which represents “good” usability. After evaluating the technology acceptance questionnaire, it can be concluded that the lay user group is open to mobile devices as interview tools.

CONCLUSIONS

The usability evaluation results show that a lay user group generally agree that data collecting partners in the digiDEM project can handle the REDCap app well. The usability evaluation provided statements about positive aspects and could also identify usability issues relating to the REDCap app. In addition, the current technology acceptance in the sample showed that heterogeneous groups of different ages with diverse experiences in handling mobile devices are also ready for the use of app-based EDC systems. Based on these results, it can be assumed that the offline use of an app-based EDC system on mobile devices is a viable solution for collecting data in a decentralized registry–based research project.

Authors: Putra Alun Sagara , Aditya Trias
Published: June 2021

Keberadaan MRT dan LRT Jakarta bertujuan untuk melakukan perubahan pada pola penggunaan transportasi, dari transportasi pribadi menjadi transportasi umum. Berdasarkan data Menteri Perhubungan, hanya 32% warga Jakarta yang sehari-harinya menggunakan transportasi umum. Untuk meningkatkan minat pengguna transportasi umum, maka dibutuhkan informasi yang lengkap mengenai berbagai pilihan akses transportasi. Tujuan kegiatan ini yaitu untuk menampilkan informasi peta jaringan MRT/LRT Jakarta dan peta interaktif story map hasil analisis Transit-Oriented Development (TOD) dan service area pada tiap stasiun sebagai penunjang perencanaan guna mencapai transportasi yang berkelanjutan. Peta jaringan MRT/LRT Jakarta dibuat dengan melakukan proses skematisasi, yaitu mengubah peta konvensional menjadi peta skematik yang umumnya digambar lurus dengan sudut tertentu dan banyak digunakan dalam sistem transportasi kota. Peta interaktif story map dibuat melalui platform ESRI Story Map. Visualisasi analisis indeks TOD pada stasiun MRT Jakarta menggunakan hasil perhitungan yang sudah dilakukan oleh Siburian (2020), sedangkan visualisasi analisis indeks TOD pada stasiun LRT Jakarta merupakan hasil perhitungan yang diolah oleh penulis. Nilai indeks TOD dihitung berdasarkan metode Singh (2015) dengan 8 parameter. Hasil perhitungan menunjukkan bahwa dua stasiun memiliki indeks level tinggi, tiga stasiun dengan level sedang, dan satu stasiun tergolong memiliki level TOD rendah. Kegiatan ini menghasilkan sebuah website yang tersusun atas dua halaman yaitu halaman beranda dan halaman peta. Halaman beranda berisi informasi umum seperti sejarah, tarif, dan waktu perjalanan kereta. Sedangkan halaman peta merupakan halaman inti dari website yang disajikan dalam bentuk peta statik skematik dan peta interaktif story map. Data spasial terkait titik-titik penting, rute perjalanan, kependudukan, serta penggunaan lahan divisualisasikan pada peta sebagai fitur spasial. Berdasarkan hasil evaluasi dari pengguna, website yang dihasilkan mampu menyajikan informasi dengan tepat, baik, dan mudah untuk operasikan.
Pembuatan Sistem Informasi Irigasi dan Kebutuhan Air dengan Standard dan Mekanisme Akses berbasis Infrastruktur data Geospasial untuk Irigasi Pertanian di Kabupaten Karanganyar
Authors: Perceka Dimas Uga , Aditya Trias
Published: June 2021

Manajemen irigasi diperlukan dalam mendukung tatakelola dan penentuan kebutuhan air, khususnya pada lahan pertanian. Manajemen irigasi tersebut dapat dioptimalkan dengan melakukan inventarisasi data irigasi di dalam sebuah web map. Inventarisasi data tersebut bertujuan agar skenario tukar guna data spasial khususnya terkait manajemen irigasi dapat berjalan optimal. Skenario tukar guna data dapat optimal apabila diseminasi informasi yang ada dapat saling terintegrasi. Permasalahan utama yaitu diseminasi informasi ataupun data terkait kebutuhan air untuk lahan pertanian ada pada sumber yang terpisah sehingga sulit untuk menganalisis hasil integrasi dari data tersebut. Permasalahan tersebut dapat diselesaikan dengan menyelaraskan data (curah hujan efektif, evapotranspirasi, porositas, total kehilangan air, efisiensi irigasi, petak irigasi, saluran irigasi dan petak irigasi) sehingga data dapat diintegrasikan dan dapat dimanfaatkan oleh pengguna. Pada tulisan ini dilakukan 5 tahapan kegiatan yaitu perencanaan dan pengumpulan data, analisis, desain sistem, implementasi dan evaluasi. Hasil yang didapat yaitu berupa web map yang digunakan untuk memfasilitasi ketersediaan dan akses data spasial yang di dalamnya terdapat data irigasi dan klimatologi. Dalam web map yang dibangun terdapat fasilitas-fasilitas diantaranya pembacaan data, penambahan data, pembaruan data, penghapusan data dan pengunduhan data. Web map yang dinamakan Sistem Informasi Irigasi dan Kebutuhan Air (SIRISKA) ini merupakan sebuah web map dinamis yang menggunakan fungsi Create Read Update and Delete (CRUD) ke basis data. Web map dibangun berdasarkan integrasi antara komponen back-end yang terdiri atas PostgreSQL (basisdata), PHP (server-side scripting), Apache (web server) dan komponen front end yang terdiri atas JavaScript, HTML dan CSS. Web map SIRISKA dievaluasi dengan beberapa parameter diantaranya efektifitas, kebergunaan, konsistensi, kejelasan arsitektural dan visual, dan kemampuan data sharing. Berdasarkan evaluasi tersebut dapat disimpulkan bahwa sistem informasi yang dibuat dapat memudahkan pengguna untuk melakukan tukar guna data dan mendapatkan informasi kebutuhan air irigasi untuk setiap petak irigasi.

Too isolated, too insular: American Literature and the World
Authors: Wilkens Matthew
Published: June 2021

Are American authors homers? Do they devote too much of their attention to American concerns and settings? Is American literature as a whole different from other national literatures in its degree of self-interest? We attempt to answer these questions, and to address related issues of national literary identity, by examining the distribution of geo-graphic usage in more than 100,000 volumes of American, British, and other English-language fiction published between 1850 and 2009. We offer four principal findings: American literature consistently features greater domestic attention than does British literature; American literature is, nevertheless, significantly concerned with global loca-tions; politics and other international conflicts are meaningful drivers of changing literary attention in American and British fiction alike; and prize-nominated books are the only examined subclass of American fiction that has become significantly more international in the decades after World War II, a fact that may account for readers’ unfounded percep-tion of a similar overall shift in American literature.

Methods:
This retrospective cohort study identified patients who underwent video-assisted thoracic surgery (VATS) lobectomy for lung cancer from January 2016 to December 2018 in a Chinese tertiary general hospital. The electronic hospital medical records associated with the VATS lobectomy for lung cancer were the data sources.
Results:
Based on the analysis of 433 patients with the utilization of staplers in their VATS lobectomy for lung cancer, using powered stapler was associated with significantly shorter operation time and postsurgery hospital stay length than using the manual stapler in the multivariable generalized linear regression analyses with the adjustment of patient characteristics. However, no other significant differences were observed for other clinical outcomes between the two staplers.
Mejora del impacto mediante difusión de la investigación en redes sociales: #PublicaSalutIB
Authors: Pastor-Ramon Elena , Páez Virgili
Published: June 2021

Objetivo. El principal objetivo de la biblioteca es facilitar el acceso a la información a sus usuarios. Las bibliotecas científicas deben también centrarse en la contribución científica y en los resultados de la investigación de sus instituciones. Metodología. En el Sistema Sanitario Público de las Illes Balears hay 16.300 profesionales de diferentes categorías, que trabajan en siete hospitales y 56 centros de atención primaria. La Biblioteca Virtual de Ciencias de la Salud de las Illes Balears (Bibliosalut), creada en 2003 (Páez et al., 2013; Páez Cervi, 2005), empezó a tener presencia en redes sociales en 2012 (Pastor-Ramon, Páez y Sastre-Suárez, 2014). Desde un principio se quisieron difundir los resultados de la investigación de los profesionales del Servicio Sanitario Público de las Illes Balears, utilizando para ello el hashtag #PublicaSalutIB. Con esta etiqueta se quería dar la opción de que cualquier investigador de las Illes Balears pudiera utilizarla, independientemente del centro en el que trabajara. Conclusiones. Este servicio mejora la relación usuario-biblioteca, ya que los autores conocen su utilidad y la visibilidad que da a sus investigaciones. En más de ocho años se ha dado difusión, a través de las redes sociales, a más de 2.900 documentos y, desde 2015, se añadió la publicación de una noticia en el portal www. infosalut.com, un producto de Bibliosalut. Al brindar una información de la referencia bibliográfica y su difusión en redes sociales conseguimos, además, que se genere un impacto inmediato, que puede ser medido gracias a métricas complementarias como Altmetric y PlumX, lo que también puede influir en la valoración que recibe cada trabajo.
El rol de los medios de comunicación tradicionales en la disputa democrática de América Latina en el siglo XXI: El Caso de Grupo Globo en Brasil
Authors: Serna González Luis Antonio
Published: June 2021

América Latina se ha configurado como un territorio de disputa democrática en los últimos años. Esta contienda se ha intensificado entre dos grandes proyectos políticos: el neoliberalismo y el progresista. Así, se han diseñado diversas estrategias políticas sin comprometer a la propia democracia, destacando el uso de los medios de comunicación tradicionales. Éstos se han convertido en una potencial herramienta política utilizada principalmente por el proyecto neoliberal, desarrollando una habilidad para emplear su uso en contra del proyecto progresista. Este trabajo reflexiona sobre el rol de los medios de comunicación, resaltando el papel de grupo GLOBO en Brasil para los procesos de impeachment en contra de Dilma Rousseff y el encarcelamiento de Luiz Inácio da Silva.
Bosquejo de una cultura política estudiantil mexicana. Un acercamiento a la concepción política de los estudiantes de la Escuela Nacional de Jurisprudencia (1880-1910).
Authors: Tepos Navarro Hans Cristian
Published: June 2021

La comprensión de los procesos políticos, sociales y culturales del México de finales del siglo XIX sería incompleta si dejamos de lado, como actor significativo, a los estudiantes de jurisprudencia. El propósito de este artículo es analizar la cultura política del estudiantado de la Escuela Nacional de Jurisprudencia a partir de sus producciones académicas, en especial, de sus conferencias y tesis. Con tal fin, se harán uso de las herramientas analíticas propuestas por Gabriel Almond para el estudio de la cultura política, establecidas en tres dimensiones: elementos cognitivos, afectivos y evaluativos.
La Universidad del presente en la era global neoliberal
Authors: Magallón Anaya Mario
Published: June 2021

Hoy en día las Universidades del mundo tienen que reconfigurar y reestructurar sus proyectos académicos y de investigación, que vayan más allá de la conciencia positivista, neopositivista e hiperpragmática del sistema capitalista neoliberal global y busquen nuevas alternativas contra la desigualdad, la exclusión, el hambre, la destrucción del medio ambiente, desde un horizonte ético mundial. Ante este panorama en que se encuentran inmersas la Universidad y la Educación Superior en el mundo, requiere replantear la posibilidad de construir un sendero de desarrollo económico y un proyecto ético-político más igualitario como práctica solidaria con nosotros y los otros, que supere los principios del capitalismo, como el egoísmo, el individualismo, la exclusión social y de género. Allí donde se dé una práctica social solidaria de equidad con justicia, a partir de una democracia social radical.
