Authors: Guerreiro António Manuel , Roque Maria Teresa
Published: October 2020

Uma incapacidade cognitiva, física, social ou emocional não pode constituir um impedimento à participação social e ao sucesso das crianças numa escola inclusiva e democrática. Este estudo centra-se na problemática da avaliação de alunos com necessidades educativas especiais do 2.º ciclo no ensino básico, concretamente dos alunos com currículo específico individual. O estudo analisa as práticas de avaliação docente destes alunos, assumindo como objetivos: (i) a identificação das práticas de avaliação dos alunos com currículo específico individual; (ii) a compreensão sobre o modo como o currículo específico individual é influenciado pelo desempenho dos alunos; (iii) o conhecimento das perspetivas dos professores face à avaliação destes alunos, bem como à inclusão dos mesmos na turma e na escola. O estudo adotou uma metodologia qualitativa centrada no paradigma interpretativo, realizando um estudo de caso de dois alunos, João e Pedro (nomes fictícios), com currículo específico individual, incluídos numa mesma turma do 5.º ano, integrando, no estudo, seis professores do 2.º ciclo do ensino básico, do conselho de turma, de um Agrupamento de Escolas do distrito de Faro, Portugal. Os instrumentos de recolha de dados constituíram-se por entrevistas semiestruturadas, conversas informais e análise documental. Os dados recolhidos foram objeto de análise de conteúdo tendo por referência um sistema de categorias surgidos das opiniões dos professores entrevistados. As conclusões apontam para a necessidade de realçar o contributo que a avaliação tem para o sucesso dos alunos, para a reestruturação do currículo específico individual e para o papel dos professores no desenvolvimento de práticas de avaliação formativas. Estas contribuem para as aprendizagens dos alunos com necessidades educativas especiais, em que as relações interpessoais, o reforço positivo e a autoestima são primordiais.
INNOVACIÓN A TRAVÉS DEL ARTE EN LA ESCUELA
Authors: Ripoll Lluquet María del Rocio
Published: October 2020

El arte en la educación es muy importante.  Muchas veces, y a pesar de estar siempre presente en las aulas, pasa a formar parte de alguna asignatura secundaria, en ocasiones, pasando desapercibido, y solo se recurre a él cuando se le necesita; ya sea para un proyecto, un regalo… Nosotros, como docentes, rara vez nos damos cuenta de lo esencial que puede llegar a ser, pues permite a su vez adquirir competencias que son imprescindibles para el desarrollo de los alumnos.Las escuelas de hoy en día se esfuerzan por llevar un aprendizaje basado en proyectos, en la que se les pide a los alumnos la capacidad de trasladar sus conocimientos al mundo real; y este aprendizaje basado en proyectos, lleva implícito el arte, la necesidad de crear. Y hablando de proyectos y de la importancia de dar rienda suelta a la imaginación,  ¿Es posible recurrir al arte como elemento esencial para trabajar este tipo de educación? ¿Podría la animación ser capaz de transmitir los conocimientos adquiridos y trabajar de la mano de la creatividad?Pues bien, en este proyecto, se hace uso de la animación, en concreto, de la técnica del Stop motion, para que los alumnos puedan traspasar sus conocimientos adquiridos en las distintas materias, sin dejar de lado su creatividad. Pues con ella, se puede llevar a cabo este tipo de proyectos que relacionan las distintas áreas y de los que tan centrados están las escuelas de hoy en día. Por su atractivo y fácil uso en el aula, se convierte en una herramienta idónea para trabajarla en clase. Dando lugar a proyectos  más cercanos y creativos capaces de plasmar el aprendizaje adquirido y sin dejar de lado a la creatividad, que tan importante es.Como educadores, es nuestro deber tener siempre presente el arte en nuestras clases, pues es tan importante saber desarrollar los conocimientos adquiridos y plasmarlos en el mundo real, como desarrollarlos a través de proyectos que den rienda suelta a esa creatividad.

Evaluación y autoevaluación de los estudiantes mediante la gaminifación y el uso de recursos tecnológicos
Authors: Palací-López Daniel , Palací Jesús
Published: October 2020

La reestructuración de los contenidos impartidos en las asignaturas que forman los planes de estudio, así como su ubicación en los mismos, a consecuencia de la redefinición de los últimos planes de estudio, ha dificultado en buena medida la forma en que debe enfocarse el proceso de enseñanza-aprendizaje. A esto se suma el hecho de que muchos alumnos que acceden a la universidad lo hacen con un nivel de conocimientos generalmente inadecuado para el nivel exigido en diversas asignaturas. El presente trabajo se centra, por todo ello, en la propuesta de actividades y uso de medios tecnológicos para la evaluación de los resultados de aprendizaje. Esto se debe a que el grado en que se haya logrado la optimización del proceso de enseñanza-aprendizaje vendrá determinado por la medida en que se hayan conseguido una correcta asimilación de los contenidos de cada materia y la adquisición de las competencias requeridas. La correcta y eficiente evaluación de dicha asimilación resulta, por tanto, indispensable. Para ello se propone, haciendo uso de la gamificación, una actividad por equipos de no más de 8 alumnos. Cada equipo deberá responder a una serie de cuestiones relacionadas con la materia, compitiendo con el resto de equipos por la máxima puntuación. El uso de “Plickers” permitirá recoger todas las respuestas de forma eficiente y precisa, y da la oportunidad a los estudiantes de conocer sus resultados y ‘autoevaluarse’ en tiempo real. De este modo se propicia el trabajo en equipo, y tanto el profesor como los estudiantes revisan los conceptos trabajados y evalúan los resultados de aprendizaje adquiridos.

Published: October 2020

Music festival is one of the special event. It is a unique cultural event which continuously held on a particular place and time. It has been confirmed that music festivals can attract people to visit the destinations for instance Glastonbury, and the Fuji Rock. Various researches have explored the potential of festivals in forming destination image. It has not been yet explored a link between the music festivals and image formation of thedestination. The research aim is to examine the effect of music festivals on the perceived images of destinations. The objectives are to explore music festival in Thailand and to examine the perception of tourists towards destination image influenced by music festival.Music festivals in Thailand have been studied and 5 music festivals were chosen as the research settings. The documentary study was used to examine the 5 music festivals. Then the semi-structured interviews were conducted with tourists who have visited at least one of the five selected music festivals. The qualitative data are analysed using thematic analysis.The findings show that the destination images are influenced by the music festivals. The perceived images of the destination may similar to the existing images, while some may differ and transferable. The findings also show that the participants perceiveimages of the place differently during the music festival. The results can be applied to destination marketer in order to create or shape the destination images.

Authors: Sánchez Estrada Omar Eduardo , Urbina Pérez Mario Gerson , Pérez González Karla Georgina
Published: October 2020

The purpose of this article is to analyze the different strategic models to understand and identify the factors that hinder the ability to develop divergent, open thinking free of technical and emotional bias to produce new and valuable things, or to apply solutions in a wide variety of ways. Studies on creators in the field of psychology, the process of development of traditional creativity applied in the degree in industrial design of the University Center UAEM Valle de Chalco in Mexico, and analogical reasoning through the sources of inspiration for creative production were taken into account. The information theory called "Hamming Distance" was used to verify if the real estimated value is congruent with the ideal estimated value, numerical values obtained from the different strategic models for creativity and postures emitted by the teachers of the area. As a result, new parameters were obtained to educate more effectively towards a creative thinking of industrial designers.

Digital skills for workplace mentors in construction sector apprenticeships (CONDAP)
Authors: Peñalvo-López Elisa , Cárcel-Carrasco Javier , Llinares-Millán Jaime , Valcuende-Payá Manuel
Published: October 2020

Employers in the construction industry are regularly and increasingly reporting hiring difficulties, since the sector is experiencing a skills shortage in spite of numerous apprenticeship schemes. According to the European Construction Sector Observatory, the main reason of this skills shortage is two-fold: a) the inadequacy of VET provision, and b) the low attractiveness of the sector to young people, further hindered by the perception of its limited capacity for innovation. Correspondingly, modernising construction apprenticeships is crucial for the development of key skills and the improvement of the employability of young construction workers. Training the trainers and mentors to become more engaged and involved in the design of apprenticeships and to introduce new methods, digital tools, and innovative content during their teaching practices is essential to make training more flexible and effective. Such an approach could effectively address the misalignment between VET offerings and the demand for skills and innovation in the construction sector. This article shows the focus of the European project CONDAP, whose purpose is to improve learning in the construction sector.

Published: October 2020

Para desarrollar una educación que propicie una sociedad más crítica, justa e igualitaria es necesario contar con material didáctico que facilite la incorporación de perspectivas transversales en todas las materias. Ello fomentará el aprendizaje reflexivo y duradero. En concreto, en la docencia del Derecho preconcursal, tanto en el ámbito universitario como previo -en la Enseñanza Secundaria, el Bachillerato y la Formación Profesional- puede ser valioso el recurso didáctico a la pintura y la xilografía, que permitirán ilustrar los principios y las connotaciones sociales, económicas y jurídicas de esta parcela jurídica y que favorecerá un enfoque vivamente crítico sobre la materia societaria y de la crisis económica de los empresarios y de los particulares. Este trabajo atiende a esta innovadora propuesta docente.
The dynamics of the relationship between just-for-fun online harassment and perceived school safety
Authors: Rad Dana , Roman Alina , Dughi Tiberiu , Demeter Edgar , Rad Gavril
Published: October 2020

Our research team has developed the project Keeping youth safe from Cyberbullying under Erasmus+, that aims to deeper understand the dynamics of cyberbullying in online environments among youth, to develop educational resources for professionals involved in youth activities in order to prevent these type behaviours, to develop youth skills to protect themselves from cyberbullying and to disseminate findings among educational professionals. A 7 section online questionnaire was designed, aiming to gather descriptive data, general perception about the frequency and typology of cyberbullying type incidents, perceptions about the safety of the educational environment and parental support and an auto evaluation scale centred on self-efficacy perceptions. Data was collected from 92 participants. Present’s study interest is in analysing the relationship between perceived school safety and just-for-fun online harassment. In order to test our hypothesis that assumes that between perceived school safety and just-for-fun online harassment there is a dynamic relationship, we have used a confirmatory factor analysis, based on multiple regression analysis for curvilinear effects. Results confirm the dynamic relationship between perceived school safety and just-for-fun online harassment, meaning that the poorer and as well as the stronger school safety is perceived, just-for-fun online harassment is present in educational contexts; a fair school safety perception intrigues an almost non-existent just-for-fun online harassment among pupils/students. Qualitative results and cyberbullying prevention strategies are discussed.

El futuro profesional de la informática recibe una escasa formación en lo que respecta a su vinculación con el marco legal, político y económico del sector europeo. A pesar de que las implicaciones laborales son muchas, las más de las veces el parco acercamiento suele quedarse en un estado teórico y escaso. Con la presente experiencia se busca acercar al alumnado al contexto europeo legal técnico y económico que rodea a la firma electrónica. Este elemento está vinculado con la autentificación e identificación electrónica de ciudadanos europeos en los servicios ofrecidos por el sector público y privado dentro del Mercado Único Digital. Esta estrategia es promovida por la Unión Europea como un paso más dentro de la teoría de la integración de mercados. La involucración de los autores en este contexto es debido a su participación en el  proyecto financiado por la Comisión Europea denominado ‘Cross-border authentication in European cloud platforms according to the eIDAS Regulation (EUROLogin), de cuyos resultados se deriva información de interés para el seguimiento e investigación por parte del alumnado.
Effect of dietary antioxidant supplementation on rabbit performance, meat quality and oxidative stability of muscles
Authors: Minardi P. , Mordenti A.L. , Badiani A. , Pirini M. , Trombetti F. , Albonetti S.
Published: September 2020

The aim of this study was to cast light on the effects of EconomasE™ (EcoE), a patented pre-mixture of nutritional additives consisting mainly of organic selenium (0.15 or 0.30 mg/kg feed; Se) combined with vitamin C (5 and 10 mg/kg feed; VC), compared to DL-α-tocopherol acetate (100 or 200 mg/kg feed; VE) dietary supplementation on rabbit performance and meat quality. In fact, the role of Se supplementation in the rabbit diet has not yet been elucidated in the literature and, more specifically, there are no studies on the possible synergistic action between organic Se compared with VE on lipids, fatty acids (FA) and the oxidative stability of two glycolytic muscles, longissimus lumborum (LL) and biceps femoris (BF). Two hundred and seventy New Zealand White rabbits were divided into five dietary groups of 54 rabbits each: 1) control (basal diet = BD; CTRL); 2) VE100 (BD + VE100 mg/kg); 3) VE200 (BD + VE200 mg/kg); 4) EcoE100 (BD + EcoE100 mg/kg); and 5) EcoE200 (BD + EcoE200 mg/kg). Neither of the antioxidant treatments affected growth performance, carcass traits or meat characteristics. Lipid and fatty acid contents were similar in LL and BF and not influenced by the dietary treatment. Meat oxidative stability was strongly improved by both antioxidants. These findings indicate that both EcoE and VE greatly improved the oxidative stability of LL and BF muscles at the dosage rates which, from an economic point of view, would normally be included in the formulation of feeds for rabbits.
Preliminary evaluation of fenugreek (Trigonella foenum-graecum) seed gum as a potential prebiotic for growing rabbits in Tunisia: effects on in vivo faecal digestibility and in vitro fermentation

Published: September 2020

This study aims to determine the effect of dietary inclusion of fenugreek seed gum (FSG), rich in galactomannans, on nutrient apparent digestibility and caecal environment, as well as on in vitro caecal fermentation of Tunisian growing rabbits. Three experimental diets were formulated, including 0, 0.25 and 0.5% of FSG (FSG0, FSG0.25 and FSG0.5, respectively) for the in vivo trial and 0, 0.125, 0.25, 0.5 and 100% of FSG (FSG0, FSG0125, FSG0.25, FSG0.5 and FSG100, respectively) for the in vitro trial. In the in vivo trial, 45 weaned rabbits 31 d old (15 per treatment) were housed in individual cages until 94 d of age. Apparent digestibility coefficients were determined at two ages, from 38 to 41 and from 56 to 59 d old, and caecal traits were recorded after slaughtering. In the in vitro trial, the five experimental diets were incubated with a rabbit caecal inoculum. Gas production was measured and modelled until 72 h and the fermentation traits were measured. Apparent faecal digestibility coefficients of main nutrients and main caecal environment traits were not significantly affected by the dietary inclusion of FSG (P>0.05). However, animals fed with FSG showed lower caecal pH (–0.15; P<0.05) values. Regarding the in vitro fermentation, FSG100 increased asymptotic gas production (+11.25, P<0.001), sharpness of the switching characteristic of the profile (+1.98, P<0.001) and the maximum substrate degradation rate (RM) (+0.188, P<0.001), but decreasing the time after incubation at which half of the asymptotic amount of gas has been formed (–5.86, P<0.001) and at which RM occurs (–4.53, P<0.01). Likewise, FSG100 significantly decreased caecal pH (–1.035, P<0.001), lactic acid (–9.51, P<0.069) and N-NH3 concentrations (–12.81, P<0.001). Meanwhile, it increased the total volatile fatty acids (VFA) production (+43.15, P<0.001). Gradual dietary inclusion of FSG from 0 to 0.5% only significantly increased total VFA production in the caecum (+100 mmol/L per percentage point of FSG inclusion; P<0.05). In conclusion, FSG is highly and rapidly in vitro fermented by rabbit caecal bacteria. However, dietary inclusion of FSG up to 0.5%, might be insufficient to affect the apparent digestibility and fermentation profile of growing rabbits to a great extent.

Published: October 2020

Abstract. Vertically integrated water vapour (IWV) is expected to increase globally in a warming climate.
To determine whether IWV increases as expected on a regional scale, we present IWV trends in Switzerland from ground-based remote sensing techniques and reanalysis models, considering data for the time period 1995 to 2018.
We estimate IWV trends from a ground-based microwave radiometer in Bern, from a Fourier transform infrared (FTIR) spectrometer at Jungfraujoch, from reanalysis data (ERA5 and MERRA-2) and from Swiss ground-based Global Navigation Satellite System (GNSS) stations.
Using a straightforward trend method, we account for jumps in the GNSS data, which are highly sensitive to instrumental changes.
We found that IWV generally increased by 2 % per decade to 5 % per decade, with deviating trends at some GNSS stations.
Trends were significantly positive at 17 % of all GNSS stations, which often lie at higher altitudes (between 850 and 1650 m above sea level).
Our results further show that IWV in Bern scales to air temperature as expected (except in winter), but the IWV–temperature relation based on reanalysis data in the whole of Switzerland is not clear everywhere.
In addition to our positive IWV trends, we found that the radiometer in Bern agrees within 5 % with GNSS and reanalyses.
At the Jungfraujoch high-altitude station, we found a mean difference of 0.26 mm (15 %)
between the FTIR and coincident GNSS data, improving to 4 %
after an antenna update in 2016.
In general, we showed that ground-based GNSS data are highly valuable for climate monitoring, given that the data have been homogeneously reprocessed and that instrumental changes are accounted for.
We found a response of IWV to rising temperature in Switzerland, which is relevant for projected changes in local cloud and precipitation processes.

Abstract. The mid-Holocene (6000 years ago) is a standard time period for the evaluation of the simulated response of global climate models using palaeoclimate reconstructions. The latest mid-Holocene simulations are a palaeoclimate entry card for the Palaeoclimate Model Intercomparison Project (PMIP4) component of the current phase of the Coupled Model Intercomparison Project (CMIP6) – hereafter referred to as PMIP4-CMIP6. Here we provide an initial analysis and evaluation of the results of the experiment for the mid-Holocene. We show that state-of-the-art models produce climate changes that are broadly consistent with theory and observations, including increased summer warming of the Northern Hemisphere and associated shifts in tropical rainfall. Many features of the PMIP4-CMIP6 simulations were present in the previous generation (PMIP3-CMIP5) of simulations. The PMIP4-CMIP6 ensemble for the mid-Holocene has a global mean temperature change of −0.3 K, which is −0.2 K cooler than the PMIP3-CMIP5 simulations predominantly as a result of the prescription of realistic greenhouse gas concentrations in PMIP4-CMIP6. Biases in the magnitude and the sign of regional responses identified in PMIP3-CMIP5, such as the amplification of the northern African monsoon, precipitation changes over Europe, and simulated aridity in mid-Eurasia, are still present in the PMIP4-CMIP6 simulations. Despite these issues, PMIP4-CMIP6 and the mid-Holocene provide an opportunity both for quantitative evaluation and derivation of emergent constraints on the hydrological cycle, feedback strength, and potentially climate sensitivity.

Abstract. Holocene climate reconstructions are useful for understanding the diverse features and spatial heterogeneity of past and future climate change. Here we present a database of western North American Holocene paleoclimate records. The database gathers paleoclimate time series from 209 terrestrial and marine sites, including 382 individual proxy records. The records span at least 4000 of the last 12 000 years (median duration = 10 603 years), and have been screened for resolution, chronologic control, and climate sensitivity. Records were included that reflect temperature, hydroclimate, or circulation features. The database is shared in the machine readable Linked Paleo Data (LiPD) format and includes geochronologic data for generating site-level time-uncertain ensembles. This publicly accessible and curated collection of proxy paleoclimate records will have wide research applications, including, for example, investigations of the primary features of ocean-atmospheric circulation along the eastern margin of the North Pacific and the latitudinal response of climate to orbital changes. The database is available for download at: https://doi.org/10.6084/m9.figshare.12863843.v1 (Routson and McKay, 2020).
Preferential water flow through decayed root channels enhances soil water infiltration: Evaluation in distinct vegetation types under semi-arid conditions
Authors: Wu Gao-Lin , López‐Vicente Manuel , Huang Ze , Cui Zeng , Liu Yu
Published: October 2020

Abstract. Topsoil desiccation alters soil physical characteristics and seriously limits plant growth in semi-arid and arid areas. The phenomenon of dried soil layer has generated increasing attention, but the process of preferential flow through decayed root channels – when the plants decompose after death – and its benefits on soil water supply in the soil dry layers are rarely evaluated. This study examines the effects of root channels on soil infiltrability in three contrasted vegetation types developed in a loessial soil, namely: Scrubland (Caragana korshinskii), fruit tree plantation (Armeniaca vulgaris) and grassland (Medicago sativa; using data from a previous study); setting bare land as control. The infiltration rates of the alive and decayed specimens were measured using a double-ring infiltrometer, and methylene blue allowed us to trace the pathways of water flow. Results indicated that scrubland species had the highest steady infiltration rates, which were about 23 % and 83 % higher than those rates measured in the fruit tree plantation and grasslands, respectively. Regarding root geometry, the steady infiltration rates were significantly and positively correlated with the average root channel diameter (ARCD) and area (RCA). Under the same root diameter conditions, soil water infiltrability significantly improved in the decayed root plots and compared with the alive root plots. Our findings contribute to a better understanding of the effects of root channels of different degraded vegetation types on soil moisture and infiltrability, which are conductive to provide knowledge base in the research of hydrological processes in degraded soils in water-scarce regions.
Comparison of electrical collection topologies for multi-rotor wind turbines
Authors: Pirrie Paul , Campos-Gaona David , Anaya-Lara Olimpo
Published: October 2020

Abstract. Multi-rotor wind turbines (MRWTs) have been suggested in the literature as a solution to achieving wind turbine systems with capacities greater than 10 MW. MRWTs utilize a large number of small rotors connected to one support structure instead of one large rotor with the aim of circumventing the square cube law. Potential benefits of MRWTs include cost and material savings, standardization of parts, increased control possibilities, and improved logistics for assembly and maintenance. Almost all previous work has focused on mechanical and aerodynamic feasibility, with almost no attention being paid to the electrical systems. In this research eight different topologies of the electrical collection network for MRWTs are analysed to assess which are the most economically and practically viable options. AC and DC collection networks are presented in radial, star, cluster and DC series topologies. Mass, capital cost and losses are estimated based on scaling relationships from the academic literature and up-to-date commercial data. The focus of this study is the assessment of the type of electrical collector topology, so component type and voltage level are kept consistent between topology designs in order to facilitate a fair comparison. Topologies are compared in terms of four main criteria: capital cost, cost effectiveness, total mass and reliability. A comparison table is presented to summarize the findings of the research in a convenient way. It is found that the most cost-effective solutions are the AC radial and AC star topologies, with the least cost-effective being the DC series–parallel and DC cluster topologies. This is due to the high cost of DC–DC converters and DC switchgear along with the lower efficiency of DC converters. Radial designs perform best in terms of efficiency and annual energy capture. DC systems achieve a slightly lower nacelle mass compared to their equivalent AC systems. DC topologies are generally found to be more expensive when compared to their AC counterparts due to the high cost of DC–DC converters and DC switchgear. Star topologies are considered to have the best reliability due to having no shared equipment. The most suitable collection topology for MRWTs is shown to be of the star type, in which each turbine is connected to the step-up transformer via its own cable.

Migrant and seasonal farmworkers, who are essential workers in the coronavirus global public health emergency, face unique risks to their health as well as longstanding health inequities. This commentary highlights these risks and argues that Internet access represents an underappreciated but critical part of the public health response. The authors first discuss the unique risk farmworkers face. We note the importance of Internet access in the time of physical distancing, the fact that many health outreach workers are no longer visiting camps, the need for telemedicine infrastructure, and the role of Internet access in providing connections to families in communities of origin. We describe existing efforts that have been implemented in North Carolina to raise awareness among public health and health promotion practitioners and researchers. The current coronavirus pandemic demands the attention of medical libraries, public health practitioners, and policy makers to address the digital divide for farmworkers and their families.

Authors: Martin Heather J. , Schwartz Amanda
Published: October 2020

While institutional repositories are common in medical schools and academic health centers, they have been used by only a small number of health systems to track and promote their research and scholarly activity. This article describes how Providence System Library Services leveraged their existing institutional repository platform to substitute a virtual showcase for an annual in-person event.Virtual Projects are published on an annual basis in the Journal of the Medical Library Association (JMLA) following an annual call for virtual projects in MLAConnect and announcements to encourage submissions from all types of libraries. An advisory committee of recognized technology experts selects project entries based on their currency, innovation, and contribution to health sciences librarianship.

Avocado toast and pot roast: exploring perceptions of generational communication differences among health sciences librarians
Authors: Stark Rachel Keiko , McElfresh Jenessa
Published: October 2020

Objective: This research explored health sciences librarians’ perceptions of intergenerational communication in the workplace.Methods: The authors developed and sent a survey to health sciences librarians through email discussion lists from August 2018 to September 2018. A chi-square test was performed to determine whether one’s length of employment as a librarian was associated with belief that age and/or generation impacts communication in the workplace.Results: A total of 150 respondents from 5 countries completed the survey. There was no significant association between length of employment as a librarian and respondents’ belief that age and/or generation impacts communication in the workplace. However, regardless of length of employment, most respondents indicated that generational differences do have an impact on communication in the workplace. Also, most respondents expressed interest in institutional initiatives to foster intergenerational communication.Conclusion: The authors found that health sciences librarians believe that differences among generations impact communication in the workplace. Librarians, managers, and library organizations should consider providing training and other opportunities for health sciences librarians to improve their intergenerational communication skills.
How to build an HIV out of care watch list: Remaking HIV surveillance in the era of treatment as prevention
Authors: Molldrem Stephen
Published: October 2020

This paper describes how state and local departments of public health (DPHs) in the United States build HIV “out of care” lists using “Data to Care” guidance from the Centers for Disease Control and Prevention (CDC). DPHs use these lists in prevention outreach and contact tracing. DPHs build out of care lists using data sent to them by laboratories every time a clinician orders routine HIV-related bloodwork for a patient. If a person does not report bloodwork, or shows poor results, they can be placed on an out of care list. The processes DPHs use to construct and refine lists show how HIV care data changed during the 2010s, transforming from a class of sensitive information with many restrictions governing its exchange into a class of data that is accompanied by a mandate for public health actors to exchange and utilize it in a variety of programs. Re-uses of HIV care data for prevention follow confirmation that antiretroviral therapy for HIV is an effective way to prevent transmission, a paradigm called “treatment as prevention.” DPH personnel enhance lists by conducting investigations, matching lists against medical records, utilizing people search tools such as LexisNexis, searching social media platforms, and other methods. This can include collaboration with correctional and law enforcement agencies — a concern in jurisdictions where HIV nondisclosure is criminalized. Public health re-uses of HIV data are done without consent. This paper focuses on the labor and ethics of building HIV out of care lists, drawing on archival health policy data, fieldwork with the HIV/AIDS workforce in metropolitan Atlanta, and a literature review.
Estimating the interconversion between CO2 and organic matter in the environment using mathematical models and some considerations
Authors: Portes Tomás Aquino
Published: October 2020

The aims was to use mathematical models to analyze the interconversion between the amount of organic matter produced and the consequent variation in the concentration of CO2 in the atmosphere and to discuss, supported by the data presented and the literature, possible changes in the Earth's environment. Scientific findings and evidence indicate that the concentrations of CO2 and O2 varied throughout the existence of the Earth. These variations were a consequence of the existing environment in different Eras, resulting in changes in all other processes that depended on these gases. Chemical reactions occurred and organic products such as petroleum arose abiotically. These products gave origin to organic chemistry and drastically reduced the concentration of CO2 and elevated O2 in the atmosphere. In the current plants, for each O2 produced in the photochemical step of photosynthesis, one CO2 is assimilated in the biochemical step. Supported by this relationship and by the results presented in this work, it can be inferred that the first photosynthetic organisms originated on Earth when the concentration of CO2 was possibly at a concentration below 1000 ppm. Biochemistry started with these organisms. The results suggest that the reduction in CO2 concentration was linear in relation to the age of the Earth, before the origin of photosynthetic organisms. This relationship changed with origin of these organisms, due to the major changes that occurred in the environment. There is evidence that in certain periods, CO2 concentrations have been reduced below the CO2 compensation point for certain plants resulting in the extinction of these plants and the organisms that depended on them.
Barnaby Rudge, True Crime Style
Authors: Cook Susan
Published: September 2020

This article interprets Barnaby Rudge's fraught murder mystery plot through contemporary true crime podcasts. It argues that true crime podcasts illuminate a way of reading Dickens's crime plot as intrinsically connected to his historical plot. It begins by discussing true crime podcasts, the position they enjoy in our present-day, true-narrative-consuming culture, and their stylistic techniques. From there, it explains how Barnaby Rudge preempts many of these same stylistic techniques: Dickens's novel and true crime podcasts are comparable not only for how both feature a storyteller/participant and are heavily reliant on stories being told, but also on how crime is narrated messily and asynchronously. Finally, this article concludes by exploring some of the implications of bridging these forms of media—implications for reading Dickens as well as for listening to podcasts.
Young Adults’ Economic Well-Being and Mental Health: The Mediation Model of Self-Esteem
Authors: Lee Jaewon , Allen Jennifer
Published: October 2020

This study examined the relationship between economic well-being and mental health in young adults and investigated the mediating effects of young adults’ self-esteem. This study used the National Longitudinal Survey of Youth 79 for Children and Young Adults. 9,584 young adults were selected, and the mediation model was conducted. Results showed that economic well-being is related to self-esteem and depression during adulthood. Self-esteem is significantly associated with mental health among young adults. Results show evidence of partial mediation of the relationship between economic well-being and mental health by young adults’ self-esteem. Economic well-being is one of the most important factors to develop and cultivate self-esteem and reduce mental health problems during young adulthood. Economic well-being is critical for developing self-esteem during young adulthood, and this study reveals that developing higher self-esteem is important for one’s mental health during young adulthood. Self-esteem should be considered to better understand mental health during young adulthood in the context of individuals’ economic well-being.

Aim of study: Cull ewes are characterized by poor body condition, low body weights and tough meat texture. This work aimed to investigate the effect of distillated myrtle leaves (MDL) intake on body weight (BW) gain; carcass characteristics and meat quality of Barbarine cull ewes.Area of study: Northwest of TunisiaMaterial and methods: 27 Barbarine ewes were assigned into 3 groups receiving 500 g of oat hay and 750 g of concentrate control group (C), while they were given concentrate and pellets, containing 87% MDL, as substitute to hay in MHay group; for MConc group, they were fed hay, concentrate and pellets containing 30% MDL in partial substitution to concentrate. At the end of the fattening period (90 days), ewes were slaughtered.Main results: The dry matter intake was higher (p<0.05) for MConc and C groups. The average daily gain was significantly higher for C and MConc than MHay groups (113 and 107 vs. 87 g, respectively). Ewes fed MHay and MConc had a significantly lower feed conversion rate than Control group (12.5 vs. 15.4). Dietary treatment had no significant effect on carcass joint’s weight and proportions. The dressing percentage and carcass tissue composition were similar for all groups. The ultimate pH, water cooking loss and color parameters values were unaffected by the type of diet.Research highlights: These findings revealed that MDL could substitute, in ewes feeding, up to 87% to hay or up to 30% to concentrate without negative effects on body weight, carcass characteristics and meat quality.
Factors Influencing Students’ Decision to Drop Out of Online Courses in Brazil
Authors: Vasconcellos Isabella Moreira Pereira de , Robaina Diogo Tavares , Bonanni Carole
Published: September 2020

In recent years, e-learning has been the fastest growing educational form in students' numbers, and this industry's market revenue (Lee, Choi, &Kim, 2013).

Despite this growth, concern about the significantly higher student dropout rate of students in online courses as compared with conventional learning environments has increased. Brazil has also registered a significant increase in the number of students interested in this type of education, but the dropout rate is a considerable concern to institutions.

This study’s objective was to identify the relevant variables behind online students’ dropout decision in Brazil. After a literature review that determined the ten most recurrent and relevant variables, we heard professional e-learning experts. They indicated, from their standpoint, what the most pertinent variables influencing dropout would be. Based on this, we conducted a quantitative survey with e-learning students, considering the factors indicated in the literature on this subject and educational professionals’ indications.

This study's contribution was to verify that the quality support is extraordinarily relevant and has a high correlation with students' perception of Usefulness, the quality of Course Content, and ease of System Use.
