Mapping the literature of dental hygiene: an update
Authors: Watwood Carol L. , Dean Terry
Published: July 2019

Objective: This study updates Haaland’s 1999 dental hygiene mapping study. By identifying core journals and estimating database coverage, it characterizes changes in dental hygiene research and aids librarians in collection development and user education.Method: Cited references from a three-year (2015–2017) sample of core dental hygiene journals were collected, categorized into five formats, and analyzed by format and publication year according to Bradford’s Law of Scattering. CINAHL Complete, MEDLINE, and EMBASE were surveyed to determine the indexing coverage of cited journals.Results: The number of cited journal titles increased from 389 in 1999 to 1,675 in 2018. Core Zone 1 titles increased from 5 to 11. Journal article citations increased from 69.5% of all citations in 1999 to 78.4% in the present study, whereas book citations decreased from 18.1% to 5.1%. A newly added category, “Internet sources,” accounted for 8.4% of citations. Overall, 68.6% of citations were 10 years or younger versus 71.4% in 1999. Most Zone 1 and Zone 2 journals were specific to dentistry or dental hygiene.Conclusion: Notable changes since 1999 were an increased volume of literature and a shift from print to online sources, reflecting improved accessibility of the literature and greater Internet use. From 1999 to 2018, citations to journal articles increased, books decreased, websites appeared, and government publications increased slightly. These findings indicate that dental hygiene research is growing and that indexing coverage for this field has improved dramatically in the past two decades.
Mind the gap: identifying what is missed when searching only the broad scope with clinical queries
Authors: Sperr Jr. Edwin Vincent
Published: July 2019

Objective: The PubMed Clinical Study Category filters are subdivided into “Broad” and “Narrow” versions that are designed to maximize either sensitivity or specificity by using two different sets of keywords and Medical Subject Headings (MeSH). A searcher might assume that all items retrieved by Narrow would also be found by Broad, but there are occasions when some [Filter name]/Narrow citations are missed when using [Filter name]/Broad alone. This study quantifies the size of this effect.Methods: For each of the five Clinical Study Categories, PubMed was searched for citations matching the query Filter/Narrow NOT Filter/Broad. This number was compared with that for Filter/Broad to compute the number of Narrow citations missed per 1,000 Broad. This process was repeated for the MeSH terms for “Medicine” and “Diseases,” as well as for a set of individual test searches.Results: The Clinical Study Category filters for Etiology, Clinical Prediction Guides, Diagnosis, and Prognosis all showed notable numbers of Filter/Narrow citations that were missed when searching Filter/Broad alone. This was particularly true for Prognosis, where a searcher could easily miss one Prognosis/Narrow citation for every ten Prognosis/Broad citations retrieved.Conclusions: Users of the Clinical Study Category filters (except for Therapy) should consider combining Filter/Narrow together with Filter/Broad in their search strategy. This is particularly true when using Prognosis/Broad, as otherwise there is a substantial risk of missing potentially relevant citations.
Social justice and the medical librarian
Authors: Martin Elaine Russo
Published: July 2019

This lecture discusses social justice and the role that medical librarians can play in a democratic society. Social justice needs to be central to the mission of medical librarianship and a core value of the profession. Medical librarians must develop a new professional orientation: one that focuses on cultural awareness or cultural consciousness that goes beyond ourselves and our collections to that which focuses on the users of our libraries. We must develop a commitment to addressing the issues of societal, relevant health information. Using examples from medical education, this lecture makes the case for social justice librarianship. This lecture also presents a pathway for social justice medical librarianship, identifies fundamental roles and activities in these areas, and offers strategies for individual librarians, the Medical Library Association, and library schools for developing social justice education and outcomes. The lecture advocates for an understanding of and connection to social justice responsibilities for the medical library profession and ends with a call to go beyond understanding to action.The lecture emphasizes the lack of diversity in our profession and the importance of diversity and inclusion for achieving social justice. The lecture presents specific examples from some medical libraries to extend the social justice mindset and to direct outreach, collections, archives, and special collection services to expose previously hidden voices. If medical librarians are to remain relevant in the future, we must act to address the lack of diversity in our profession and use our information resources, spaces, and expertise to solve the relevant societal issues of today.

Authors: González Gabriel , Díez-Echavarría Luisa , Zapa Elkin , Eusse Danilo
Published: July 2019

Las instituciones de educación superior deben formar a sus estudiantes según requerimientos del contexto en que se desenvuelven, ya que, sobre la base de su desempeño, es donde se medirá si las políticas de desarrollo socioeconómico son efectivas. Para lograrlo, es necesario identificar el impacto de esa educación en sus egresados, y hacer los ajustes necesarios que generen mejora continua. El objetivo de este artículo es estimar el impacto académico y social de egresados del Instituto Tecnológico Metropolitano – Medellín, a través de un análisis multivariado y la estimación del modelo Average Treatment Effect (ATE). Se encontró que la educación ofrecida a esta población ha generado un impacto académico, asociado a los estudios de actualización, y dos impactos sociales, asociados a la situación laboral y al nivel de ingresos percibidos por los egresados. Se recomienda usar esta metodología en otras instituciones, ya que suele arrojar resultados más informativos y precisos que los estudios tradicionales de caracterización, y se puede medir el efecto de cualquier estrategia.
Technically white: Emoji skin-tone modifiers as American technoculture
Authors: Sweeney Miriam E. , Whaley Kelsea
Published: July 2019

The inclusion of skin-tone modifiers into the standard emoji set marked a shift from the default white racialization of emoji towards explicit attempts to expand racial representation in the human emoji characters. This study explores the racial logics of emoji as culturally-situated artifacts that rely on linked understandings of race and technology. We conduct an interface analysis of emoji skin-tone modifiers, coupled with user discourse analysis, to explore the design and user interpretations of skin-tone modifiers. Our findings suggest that though the skin-tone modifiers were introduced as an intervention into the lack of racial representation in emoji, they continue to technically center whiteness in the emoji set as an extension of American technoculture.
De la hacienda a los puertos. Los caminos en los primeros años de la República del Salvador. Siglo XVIII
Authors: Castellón Osegueda José Ricardo
Published: July 2019

Movilidad eficiente, adecuación (mejoras y mantenimiento) e integración se plantaron desafiantes a las comunicaciones de la República del Salvador en el siglo XIX. Los retos eran mayores que las posibilidades. La disgregación vial, propia del aislamiento; los recursos limitados (agotados por las guerras federales), la visión municipalista de la responsabilidad caminera y el interés apremiante de las necesidades de la nueva configuración económica fueron determinantes en la habilitación de una red en que privó un conjunto de líneas que, saliendo de las haciendas se juntaban en puntos nodales, sacando lo producido a ferias añileras y puertos. Sobre la base de la red heredada de la época colonial, los caminos constituyeron una urdimbre vial con serios problemas para hacerse carretera y gozar de mantenimiento adecuado, las mayores preocupaciones de las autoridades en el siglo, pero la base del desarrollo vial de la era cafetalera.

“Ready to do battle with the mountain”: Masculinity, Nature, and Sacrifice in Spike TV’sCoal
Authors: Thompson Peter
Published: July 2019

This article examines the way in which Coal, a Thom Beers reality television program that aired for ten episodes on Spike TV in 2011, depicts ideas about masculinity, nature, and sacrifice. Coal is the story of a group of workers in a small mine in McDowell County, West Virginia. Like other reality television shows that focus on dangerous occupations in extreme environments, Coal accentuates the macho attributes of these workers and features a group of men putting their bodies on the line in a battle against the environment. This article suggests that the show deploys ideas about nature, tradition, sacrifice, and masculinity to construct a sense of authenticity and a narrative in which these men are struggling to survive not only the dangers of the mine but also a wider set of economic and social changes taking place across North America.

Published: July 2019

The present study investigates the effects of cooperative learning on learning strategies of 72 second-year Vietnamese higher education students toward the Research Methods in Education course over a nine-week course. These students were divided into two matched groups of 36 to be taught by the same lecturer. In the control group, cooperative learning was used, while in the experimental group, lecture-based teaching was employed. Results showed that students who were instructed using lecture-based teaching had lower scores on the post-tests of resource management and cognitive - metacognitive strategies than did the students who were instructed using cooperative learning. Implications for educators and further research are suggested for a less competitive and more effective learning outcome.

O trabalho teve como objetivos avaliar o crescimento heterotrófico e potencial de remoção de DQO e nutrientes (nitrogênio e fósforo) da microalga clorofícea Desmodesmus subspicatus em esgoto doméstico coletado em estação piloto de tratamento e reúso de água do CCA/UFSCar. Os resultados indicaram velocidades específicas de crescimento máximas de 0,084 h????1, com concentrações de biomassa de 1000 mg L????1 em 24 horas de cultivo. Devido à composição do efluente esterilizado, tanto a quantidade de matéria orgânica como nitrogênio são limitantes para o crescimento microbiano. Entretanto, para valores de DQO acima de 200 mg L????1, houve uma elevada conversão de matéria orgânica do efluente em biomassa. Estes resultados sugerem a viabilidade de aplicação desta microalga para produção de biomassa e remoção de parte dos nutrientes e matéria orgânica deste efluente, podendo ser considerada como uma das etapas de adequação para reúso agrícola de esgoto doméstico.

Published: July 2019

WPPF was added into the wheat flour (WF) flour with different addition amount (0%~50%) to study the influence of whole purple potato flour (WPPF) on dough properties and quality of steamed bread. Result revealed that the WPPF addition significantly influenced the dough properties and quality of steamed bread. The water absorption, the maximum height of the gas release, total volume of CO2 release and the hardness of steamed bread significantly increased with the increase of WPPF addition amount, while decreased the dough stability, the maximum height of dough, the gas holding capacity and the specific volume. Moreover, peak viscosity, final viscosity and setback value had a remarkable decrease when 10% WPPF added, but increased following the addition of WPPF. Considering the sensory evaluation, the steamed bread with 20% WPPF is acceptable. Appropriate addition amount of WPPF improves the nutrition value and variety of steamed bread and did not effect on the quality of the quality of dough and steamed bread.

Objective: The objective of this experiment was to compare conventional antioxidants and plant extracts for oxidative stress control in lambs fed a high-concentrate diet.Methods: Forty-eight male Dorper×Santa Ines lambs with an initial weight of 20±1.49 kg and 60 days of age, were used to evaluate the effects of feeding a combination of Macleaya cordata and Magnolia officinalis plant extracts (0 vs 320 mg/kg dry matter [DM]) in combination with selenium+vitamin E (0 vs 100 IU/kg DM of vitamin E and 0.1 mg/kg DM of selenium) in a completely randomized block design in a 2×2 factorial arrangement. The animals were housed in individual pens and received a high-concentrate diet consisting of 80% whole corn and 20% protein pellet for 60 days. The animals were weighed at the beginning of the experiment and every 14 days for performance monitoring. Three blood samplings were performed during the experimental period for the evaluation of oxidative and protein parameters.Results: The treatments with vitamin E and selenium as additives had a positive influence on final weight, daily weight gain, carcass weight, and selenium content in longissimus muscle (p = 0.01). Plant extracts tended to improve final weight (p = 0.064) and daily weight gain (p = 0.059), showing similar effect as selenium and vitamin E. There was no effect of treatment on blood proteins, indicating that the animals were healthy throughout the experiment.Conclusion: The use of plant extracts had a similar effect as the addition of selenium and vitamin E, with dietary inclusion of additives resulting in better performance of lambs but both supplements did not have strong influence on oxidative stress.

Published: July 2019

Objective: This study was conducted to investigate the effect of zinc aspartic acid chelate (Zn-ASP) on growth performance, nutrient digestibility, blood profiles, fecal microbial and fecal gas emission in growing pigs.Methods: A total of 160 crossbred ([Landrace×Yorkshire]×Duroc) growing pigs with an initial body weight (BW) of 25.56±2.22 kg were used in a 6-wk trial. Pigs were randomly allocated into 1 of 4 treatments according to their sex and BW (8 replicates with 2 gilts and 3 barrows per replication pen). Treatments were as follows: i) CON, basal diet, ii) TRT1, CON+0.1% Zn-ASP, iii) TRT2, CON+0.2% Zn-ASP, and iv) TRT3, CON+0.3% Zn-ASP. Pens were assigned in a randomized complete block design to compensate for known position effects in the experimental facility.Results: In the current study, BW, average daily gain, and gain:feed ratio showed significant improvement as dietary Zn-ASP increased (p<0.05) in growing pigs. Apparent total tract digestibility (ATTD) of dry matter was increased linearly (p<0.05) in pigs fed with Zn-ASP diets. A linear effect (p<0.05) was detected for the Zn concentration in blood with the increasing levels of Zn-ASP supplementation. Lactic acid bacteria and coliform bacteria were affected linearly (p<0.05) in pigs fed with Zn-ASP diets. However, no significant differences were observed in the ATTD of nitrogen, energy and Zn. And dietary Zn-ASP supplementation did not affect fecal ammonia, hydrogen sulfide and total mercaptans emissions in growing pigs.Conclusion: In conclusion, dietary supplementation with Zn-ASP of diet exerted beneficial effects on the growth performance, nutrient digestibility, blood profiles and fecal microbes in growing pigs.

Published: July 2019

Objective: The objective of this study was to investigate the effects of low doses of organic trace minerals (iron, copper, manganese, and zinc) on productive performance, egg quality, yolk and tissue mineral retention, and fecal mineral excretion of laying hens during the late laying period.Methods: A total of 405 healthy hens (HY-Line White, 50-week-old) were randomly divided into 3 treatments, with 9 replicates per treatment and 15 birds per replicate. The dietary treatments included feeding a basal diet + inorganic trace minerals at commercial levels (CON), a basal diet + inorganic trace minerals at 1/3 commercial levels (ITM), and a basal diet + proteinated trace minerals at 1/3 commercial levels (TRT). The trial lasted for 56 days.Results: Compared to CON, ITM decreased (p<0.05) egg production, daily egg mass, albumen height, eggshell strength, yolk Fe concentration, serum alkaline phosphatase activity and total protein, and increased (p<0.05) egg loss and feed to egg ratio. Whereas with productive performance, egg quality, yolk mineral retention, and serum indices there were no differences (p>0.05) between CON and TRT. The concentrations of Fe and Mn in the tissue and tibia were changed notably in ITM relative to CON and TRT. Both ITM and TRT reduced (p<0.05) fecal mineral excretion compared to CON.Conclusion: These results indicate that dietary supplementation of low-dose organic trace minerals reduced fecal mineral excretion without negatively impacting hen performance and egg quality.

Published: July 2019

Objective: Evidence from previous reports indicates that pig domestication in East Asia mainly occurred in the Mekong region and the middle and downstream regions of the Yangtze River. Further research identified two new origin centers for domestic pigs in the Tibetan Plateau and the islands of Southeast Asia. However, due to the small sample size of Tibetan pigs, details of the origin and spread of Tibetan pigs has not yet been established.Methods: We analyzed mitochondrial DNA control region (D-loop) variation in 1,201 individuals from nine Tibetan pig populations across five provinces. Comprehensive Tibetan pig samples were taken to perform the most detailed analysis of Tibetan pigs to date.Results: The result indicate that Rkaze pigs had the lowest level of diversity, while Changdu pigs had the highest diversity. Interestingly, these two populations were both in the Tibetan Plateau area. If we calculate diversity in terms of each province, the Tibetan Plateau area had the lowest diversity, while the Chinese province of Gansu had the highest diversity. Diversity gradient analysis of major haplotypes suggested three domestication centers of Tibetan pigs in the Tibetan Plateau and the Chinese provinces of Gansu and Yunnan.Conclusion: We found two new domestication centers for Tibetan pigs. One is in the Chinese province of Gansu, which lies in the upstream region of the Yellow River, and the other is in the Chinese province of Yunnan.
TRIBUTAÇÃO NAS OPERAÇÕES DE TRANSFERÊNCIA ELETRÔNICA DE DADOS - DOWNLOAD E STREAMING (ISS X ICMS)

Published: July 2019

O presente artigo pretende trazer algumas considerações e alguns entendimentos acerca da tributação sobre as operações comerciais via transferência de dados na perspectiva das legislações do Imposto sobre Serviços (ISS) e do Imposto sobre Circulação de Mercadorias (ICMS), haja vista a crescente ampliação do uso de tecnologias, sobretudo em razão do significativo desenvolvimento de ferramentas de streaming e download na última década, o que, naturalmente, tem provocado os estados e os municípios a regulamentar a incidência de tributos sobre essas novas realidades, de forma a garantir a arrecadação tributária sobre os novos signos de capacidade contributiva. Nesse sentido, foram editados instrumentos normativos com o intuito de viabilizar a cobrança tanto do ICMS quanto do ISS sobre certas operações realizadas via transferência de dados. E é nesse contexto que o artigo ora apresentado almeja trazer luzes iniciais sobre conceitos, eventuais conflitos de competência e sobre a legalidade e constitucionalidade da tributação pretendida.

Determinar a tendência temporal da anemia em crianças de creches públicas de Belo Horizonte-MG no período de 2001 a 2011. Para tanto, foi realizada uma análise de tendência temporal da anemia determinada por série de estudo de corte transversal nos anos de 2001, 2005 e 2011, em crianças pré-escolares de seis a 72 meses pertencentes a creches públicas do Distrito Sanitário Leste de Belo Horizonte-MG. Anemia foi determinada pelo valor da hemoglobina sérica de acordo com os pontos de corte recomendados pela OMS: Hb <11,0g/dL para crianças de seis a 60 meses e Hb <11,5g/dL para idade superior. A tendência temporal da anemia apresentou estabilidade nos três cortes avaliados, sendo os resultados encontrados de 28,61% em 2001, 26,78% em 2005 e 23,64% em 2011. Não houve diferença significativa entre os percentuais de anemia por sexo. Para a faixa etária das crianças observou-se uma maior concentração de anemia na faixa etária de até 24 meses. Observou-se um decréscimo da anemia com o aumento da idade. A tendência temporal da anemia apresentou valores próximos de prevalência da doença nos onze anos avaliados, demonstrando a importância da mesma como um agravo de saúde pública.
O IMPACTO DA GLOBAL FINANCIAL CRISIS (GFC) SOBRE OS RECURSOS HUMANOS EM EMPRESAS MULTINACIONAIS NA IRLANDA
Authors: Castro Charles Alves , Pena Felipe Gouvêa
Published: July 2019

O presente artigo tem por objetivo analisar e revisar o impacto da crise financeira global sobre a gestão de recursos humanos nas empresas multinacionais na Irlanda. Foi realizada uma revisão da literatura, tomando-se como referência o estudo de Gunningle, Lavelle e Monaghan (2013) e os dados coletados em jornais, revistas, livros e periódicos científicos. A grande contribuição do artigo está relacionada ao fato de trazer um caso, a Irlanda, para demonstrar que em momentos de crises, os gestores da área de RH podem e devem ser vistos como key-players dentro das empresas, atuando de forma estratégica. Torna-se necessário que os gestores de RH, para se comunicar de forma eficaz, construam boas relações e estejam atentos a difícil tarefa de equilibrar os anseios individuais e organizacionais. Tratar o caso específico da Irlanda traz limitações do ponto de vista das generalizações, mas funciona como uma ilustração de alternativas gerenciais às empresas impactadas por “turbulências” econômicas, seja para validação das ideias propostas ou para a construção de novas.
Patrimônio Geomineiro em Diamantina (MG)
Authors: Motta Neto João Antônio
Published: July 2019

A região de Diamantina (MG) vem desde o século XVIII convivendo com a mineração do diamante, o que confere à região características muito peculiares. Durante séculos a exploração de diamantes provocou alterações na paisagem, o que pode ser constatado nos diversos sítios geomineiros existentes. Nestes sítios podem ser observadas alterações provocadas no relevo, além da presença de benfeitorias. Verifica-se também uma gastronomia identitária, topônimos, ações institucionais em curso e diversos aspectos da cultura regional, o que pode ser entendido como um verdadeiro patrimônio geomineiro regional. Objetivando sistematizar aspectos deste patrimônio geomineiro, desenvolveu-se este trabalho que encontrou um rico mosaico de aspectos relacionados a este patrimônio. Processos erosivos, a expansão imobiliária e a inexistência de políticas públicas que estimulem a geoconservação aparecem como ameaças a este patrimônio. Por outro lado vislumbra-se grande potencial de uso científico, educativo e turístico, através do geoturismo, o que pode servir ao fortalecimento deste vetor de desenvolvimento regional.

Published: July 2019

A pedodiversidade é entendida como a variação das classes de solo em uma determinada unidade espacial, desta forma está intrinsecamente relacionada com a modelagem terrestre. Esta pesquisa foi realizada na porção Meridional da Serra do Espinhaço na Depressão de Gouveia. Esta região apresenta algumas singularidades no que se refere à evolução pedogeomorfológica, uma vez que esta é formada através da retração das escarpas quartizíticas do Supergrupo Espinhaço, gerando a exumação do embasamento e, conseqüentemente, uma nova configuração da paisagem como alteração do nível de base, entalhamento de canais fluviais, coluvionamentos, entre outros. Esta pesquisa foi realizada a partir metodologia de BOULET et al. (1982), que permite uma análise de detalhe, contribuindo para o entendimento da organização dos solos. Por meio disso, pôde-se determinar os pontos de interesse para a análise micromorfológica.Outra técnica utilizada foi o GPR (Georadar), para identificar as formações que seriam in situ e as formações coluviais a partir da utilização de antenas de 100MHz. As análises de textura dos solos, que revelaram uma sequência granulométrica com grande quantidade de argila em alguns perfis amostrados, revelando um alto grau de intemperização. A micromorfologia foi uma técnica de grande importância na identificação precisa das características dos perfis, não foi possível identificar evidências claras de formação coluvial. Análises químicas, forneceram resultados importantes, principalmente, no que se refere à evolução do manto de intemperismo. Finalmente, a técnica do GPR auxiliou muito nas conclusões sobre a origem do pavimento detrítico. Fato determinante, para entender o material como sendo in situ. A partir dessa caracterização, torna-se evidente que não há como entender e caracterizar os solos de uma determinada região, sem que antes não haja um estudo aprofundado da Geomorfologia, importante para estudos com esses finsPalavras–chave: Pedodiversidade, Micromorfologia, GPR

Published: July 2019

This paper presents the methodology for strategic posture determination of SMEs. The methodology itself that is explained in detail is based on the original work of A. Rowe and the research has been conducted on the sample of 179 companies from an emerging market of various sizes, ownership structures and industry sectors. A modified strategic analysis tool for defining company’s strategic posture (modified Strategic Position & Action Evaluation - SPACE analysis) presented in this paper investigates the basic dimensions of external environment and enterprise itself: environment stability (ES) and industry strength (IS), as well as competitive strength (CS) and financial strength (FS). Along with the presented mathematical modelling that determines resultant vector describing the strategic posture, the paper presents the mean scores of each variable from the questionnaire results that are calculated for every strategic posture. The results obtained contribute to the precise definition of the strategic position of companies and are useful for future works related to small and medium-sized firms' strategic posture evaluation.

Published: July 2019

Lasers are high-intensity beams that typically have a very pure frequency or wavelength. They come in sizes ranging from approximately one-tenth the diameter of a human hair to that of a very large. There are many applications of lasers which benefit from a uniform optical intensity distribution. Laser Beam is also a thermal process which includes the visible range of the electromagnetic spectrum. According to pilot study Huygens ’ principle, we can approximate a particular wave front by assuming every point on it is a point source of light from a single slit diffraction. In this work, we based on the alternating distribution of the maximum intensity for the central zone and minimum for the secondary zones which allows us to control the dynamic and thermal field by the law of Wien. The idea is to combine the propagation of electromagnetic waves of light and the natural convection of fluids. The CFD software is used as a technique to modelling the behaviour of fluid and the thermal convection with different Rayleigh numbers. .The results are presented in the form of distributions of the isotherms, the streamlines, local and average Nusselt .Thus these two processes are often classified as electro-optical-thermal processes.
Study on Swing Movable Teeth Drive with External Generating Wave Mode
Authors: Yali YI , Herong JIN , Yunfei GAO , Lei HE
Published: July 2019

An external generating wave swing movable teeth drive based on sinusoidal acceleration and quintic polynomial motion has been newly developed. This drive consists of a wave generator as the input cam, a train of movable rollers which are uniformly distributed on the fixed separator, and a ring gear as the output cam. The teeth difference between the ring gear and the rollers is two. The input and output cam are engaged with the train of rollers simultaneously. The drive thus has the advantages of large gear ratio, compact structure, high torsional rigid and steady rotation, can be integrated with pulley drive to form a pulley reducer. In this paper, the motion principle is studied and the tooth profiles are derived. On this foundation, curvature of the ring gear and pressure angles of the drive are conducted. And kinematic simulation is also carried out. A physical prototype is manufactured to demonstrate the feasibility and correctness of the theoretical analysis model of the drive. This drive can be integrated with pulley drive to form a pulley reducer, which is promising for the fields needing compact structure and large transmission ratio.
Zuschreibungsprozesse in der wissenschaftlichen Antragstellung. Eine historisch vergleichende Untersuchung der Antragsrichtlinien zur Drittmittelförderung
Authors: Velarde Kathia Serrano , Hölz Martin , Schwarz Miriam
Published: July 2019

Welche Erwartungen werden im Rahmen der Antragstellung an die Forschenden kommuniziert? Wie haben sich diese Zuschreibungen über die Zeit verändert? Um den Wandel der modernen Antragspraxis seit ihren Anfängen zu rekonstruieren und tentativ zu erläutern, wurden erstens die Archive der drei ältesten und bedeutendsten Drittmittelgeber konsultiert sowie Interviews mit Praktikern durchgeführt. In einem zweiten Schritt wurden alle zwischen 1959 und 2005 publizierten Richtlinien zur Antragstellung erhoben und systematisch ausgewertet. Aufbauend auf theoretischen Erkenntnissen zur Organisationskommunikation und dem sozialpsychologischen Positionierungsansatz, wird die organisationale Variation diskursiver Zuschreibungspraktiken in der Antragstellung sowohl fallvergleichend als auch historisch betrachtet. Dabei konnten die sich verändernden Positionierungsdynamiken in Bezug zu organisationsspezifischen Entwicklungstendenzen gebracht werden: Es wurde festgestellt, dass der periodisch steigende Wettbewerb von Antragstellern um knappe Drittmittel ab den 1970er-Jahren mit einer stärkeren Rationalisierung der Antragspraxis koinzidiert und die diskursiven Zuschreibungsprozesse tangiert haben könnte, die Förderorganisationen in ihren Antragsrichtlinien verarbeiten.

Authors: Dymitruk Maria
Published: July 2019

Challenges associated with the use of artificial intelligence (AI) in law are one of the most hotly debated issues today. This paper draws attention to the question of how to safeguard the right to a fair trial in the light of rapidly changing technologies significantly affecting the judiciary and enabling automation of the civil procedure. The paper does not intend to comprehensively address all aspects related to the right to a fair trial in the context of the automation of civil proceedings but rather seeks to analyse some legal concerns from the perspective of the Article 6 of the European Convention on Human Rights and the case-law of the European Court of Human Rights. Section 1 discusses the issues of using artificial intelligence in the justice and automation of the judicial proceedings. Section 2 is devoted to the judge supporting system based on artificial intelligence and psychological requirements of its practical use. Section 3 presents the right to a fair trial in civil cases established by the Article 6 of the European Convention on Human Rights, while subsequent sections characterize its elements with respect to the possibility to automate civil proceedings: a right to have case heard within a reasonable time in section 4 and a right to a reasoned judgment in section 5.
Living in a Spamster's Paradise: Deceit and Threats in Phishing Emails
Authors: Kikerpill Kristjan , Siibak Andra
Published: July 2019

The prevalence of using email as a communication tool for personal and professional purposes makes it a significant attack vector for cybercriminals. Consensus exists that phishing, i.e. use of socially engineered messages to convince recipients into performing actions that benefit the sender, is widespread as a negative phenomenon. However, little is known about its true extent from a criminal law perspective. Similar to how the treatment of phishing in a generic manner does not adequately inform the relevant law, a case-by-case legal analysis of seemingly independent offences would not reveal the true scale and extent of phishing as a social phenomenon. The current research addresses this significant gap in the literature. To study this issue, a qualitative text analysis was performed on (N=42) emails collected over a 30-day period from two email accounts. Secondly, the phishing emails were analysed from an Estonian criminal law perspective. The legal analysis shows that in the period of only one month, the accounts received what amounts to 3 instances of extortion, 29 fraud attempts and 10 cases of personal data processing related misdemeanour offences.

Los avatares filosóficos de la imagen a partir del cine
Authors: Aguilera Vita Sergio
Published: July 2019

Este artículo explora dos vías filosóficas de acercamiento a las imágenes iniciadas el siglo pasado. La primera, que denominamos metafísica, fue abierta por Bergson y desarrollada por Deleuze. La segunda, que clasificamos como fenomenológica, es iniciada por Sartre y completada por Merleau-Ponty. La posición central que ocupa la imagen en estas teorías permite el desarrollo de una nueva ontología que resuelve los problemas del dualismo y en la que el cine desempeña un papel principal.
Patologia em pavimentos flexíveis: estudo de caso para o estacionamento do ITPAC Porto
Authors: Gomes Matheus Lucas Brito , Silva Júnior Flávio Vieira da
Published: July 2019

As rodovias são importantes instrumentos para o transporte e desenvolvido do país, entretanto muitas se encontram sem pavimento ou má conservadas. Em rodovias sem conservação, é comum o aparecimento de patologias, como trincas, afundamentos, ondulações, exsudação, desgaste e remendos. Uma investigação dessas patologias foi realizada para uma possível restauração do pavimento do estacionamento do Instituto Tocantinense Presidente Antônio Carlos em Porto Nacional – TO, onde há a prevalência de desgaste e reparos mal executados. Os reparos no pavimento flexível foram feitos com concreto, havendo o surgimento de novas patologias, como trincas e panelas, devido a falta de aderência entre os diferentes materiais. Observou-se a presença de outras patologias, como trincas e panelas, entretanto não tanto quanto o desgaste e remendos. Sugere-se que haja uma restauração do pavimento de todo o estacionamento, ou pelo menos na parte mais afetada, devido uma parte quase não haver patologias por te pouco uso, onde deve ser retirado os reparos de concreto e novos reparos devem ser feitos, de maneira correta.
Estudio empírico del Tercer Sector en España: hacia una re-conceptualización unificada

Published: July 2019

La definición de Tercer Sector forma parte de un tipo de literatura social identificada por su ambigüedad y su disparidad terminológica. Las características que se utilizan para explicar cuál es el sector donde se ubican las entidades privadas sin fines lucrativos pueden ser comúnmente aceptadas, pero es probable que sean insuficientes para identificarlo de manera clara y exacta. Por ello, varios han sido los enfoques y las teorías justificativas del Sector No Lucrativo. En base a las premisas definidas por Salamon y Anheier y una revisión bibliográfica sistemática y profunda, este trabajo presenta una síntesis que reúne y combina los elementos esenciales que deben componer el concepto de Tercer Sector aportando dos nuevas características que deben ser añadidas a este tipo de organizaciones para asegurar su viabilidad y sostenibilidad, pudiendo así cumplir con eficiencia, eficacia y economicidad, su misión, visión y valores.

The definition of Third Sector is part of a type of social literature identified by its ambiguity and terminological disparity. The characteristics used to explain the sector where private non-profit entities are located, may be commonly accepted, but are likely to be insufficient to identify it clearly and accurately. Therefore, several approaches and theories have been used to justify the Nonprofit Sector. Based on the premises defined by Salamon and Anheier and a systematic and thorough bibliographic review, this paper presents a synthesis that gathers and combines the essential elements that must compose the concept of Third Sector, contributing with two new characteristics that must be added to this type of organizations to ensure their viability and sustainability, thus being able to fulfill their mission, vision and values with efficiency, effectiveness and economy.
El cargo y descargo como procedimiento jurídico-contable neutralizador de los desequilibrios derivados de las relaciones de agencia
Authors: Villaluenga de Gracia Susana , Llibrer Escrig Inmaculada
Published: July 2019

El método contable de cargo y descargo, un procedimiento de naturaleza más jurídica que contable, se empleaba cuando la actividad económica de la organización era confiada a un agente, circunstancia que facilita su análisis desde la Teoría de la Agencia. Tradicionalmente ha estado ligado a la toma de decisiones y al control del agente, sobre lo que existe una amplia bibliografía. Sin embargo, hasta ahora no se ha considerado como un instrumento que anula el conflicto de intereses contrapuestos surgidos en la relación entre principal y agente en una gestión delegada.El análisis de los documentos de cargo y descargo, contenido en estudios previos que tienen como base las fuentes documentales manuscritas y en los que se ha estudiado la relación entre principal y agente desde la perspectiva histórico-contable, ha permitido identificar todos los elementos característicos de la relación de agencia, inferir los intereses de principal y agentes, deducir los incentivos empleados por el principal para alinear el comportamiento de los agentes y concluir que este modo de registro era capaz de neutralizar los desequilibrios de intereses y la información asimétrica entre ambos.

This paper examines some accounting and legal aspects of the charge and discharge system and the relationship between it and the Agency Theory. This type of accounting was used when the economic activity was entrusted to an agent; it suggests that the Agency Theory is an excellent framework to analyze the accounts. Traditionally the Charge and Discharge has been linked to the decision making and control of the agent's management, on which there is a wide bibliography, however, until now, it has not been considered as an instrument to cancel conflicts that arisen in the relationship between principal and agent and getting the equilibrium of the relationship between them.We analyzed the documents and that allowed us to show different aspects as identify all characteristic elements of the agency relationship, infer the interests of principal and agents, deduct the incentives used by the principal to align the behavior of the agents and conclude that this mode of registration was able to neutralize the imbalances of interests and the asymmetric information between both.
De la Redacción a la (gran) pantalla: roles profesionales del periodismo y su representación en la ficción audiovisual
Authors: Novoa Jaso María Fernanda , Sánchez-Aranda José Javier , Serrano-Puche Javier
Published: July 2019

Desde los inicios del cine mudo, la figura del periodista ha destacado en diversos largometrajes. De forma paralela a la evolución de la industria audiovisual, este personaje se ha adaptado progresivamente a la variedad de géneros que, en la pequeña y en la gran pantalla, retratan su función social. En este sentido, los productos audiovisuales ofrecen la posibilidad de aproximar al espectador como un testigo privilegiado a los escenarios propios de la labor del periodista. Sin embargo, existe una divergencia entre la representación del periodismo en la ficción y la investigación sobre roles profesionales desarrollada en el ámbito científico de la comunicación. Este trabajo tiene como objetivo poner en diálogo las distintas tipologías del personaje periodístico representadas en la ficción audiovisual con la bibliografía académica sobre los roles profesionales. Mediante un análisis comparativo, se definen cuáles son las actitudes profesionales que predominan en cine y televisión. La investigación identifica las ocupaciones laborales más recurrentes en la ficción y el rol profesional que predomina en la representación del periodista.

Los materiales didácticos forman parte de la realidad educativa. El docente los selecciona en función del alumnado, el centro educativo, características o finalidad. En consecuencia, el material condiciona el método y homogeniza el proceso de enseñanza y aprendizaje. La realidad española de los últimos 30 años, a través de la especialización docente, ha hecho posible la evolución de los materiales escolares en educación musical.  Este artículo proporciona respuestas a algunas preguntas sobre los cambios que suscita la utilización de recursos tecnológicos y digitales en educación y reflexiona sobre particularidades de uso en el aula de música. La investigación parte del análisis de contenido de una muestra de materiales para 5º y 6º de Educación Primaria. El conocimiento de los materiales didácticos digitales y musicales y sus estrategias pedagógicas ha sido posible gracias a la elaboración minuciosa de instrumentos de análisis específicos. Este estudio permite conocer las características tecnológicas, las tareas específicas y el tipo de aprendizaje musical que ofrecen editoriales y administración pública a través de la tecnología educativa.
