THE ORION PROJECT: CONNECTING A COMMUNITY
Authors: Rhodes Richard M. , Walker Barbara
Published: March 2019

Certainly, the computer and the internet have opened up opportunities and stimulated unprecedented growth. However, even after the turn of a new century, the Digital Divide has not yet closed and sectors of people are still excluded from enjoying the opportunities and growth that now exist. El Paso Community College, in collaboration with El Paso Independent School District and the University of Texas at El Paso, have begun work to bring together all of El Paso’s independent networks into a single high-speed community network that provides online access and delivery of K-Gray education. This newly created Orion Ring Project has identified specific objectives such as delivering dual-credit enrollment classes to high school students and mentoring first-year teachers and education students in the field in order to stem high attrition rates. The next phase will involve adding other networks, such as the UTEP Internet 2 link, to the Orion Ring.
UNIVERSITY INSTRUCTORS’ REFLECTIONS ON THEIR FIRST ONLINE TEACHING EXPERIENCES
Authors: Conrad Dianne
Published: March 2019

Moving from traditional face-to-face teaching to teaching online can be a precarious process for instructors. In this qualitative study, I interviewed instructors who were engaged in online teaching, for the first time, in a graduate program at a Canadian university. All instructors had some postsecondary face-to-face teaching experience. In-depth interviews with the instructors showed that they had very little knowledge of the new medium they were entering and relied heavily on their face-to-face experiences and their own pedagogy. Instructors’ reflections on their performances centered largely on their roles as deliverers of content. They revealed very little awareness of issues of collaborative learning, of learners’ social presence, or of the role of community in online learning environments.
EVALUATING ONLINE DISCUSSIONS: FOUR DIFFERENT FRAMES OF ANALYSIS
Authors: Meyer Katrina A.
Published: March 2019

This study uses four different “frames” to analyze 17 online discussions that occurred in two doctoral level classes in educational leadership. Two of the frames were developmental models: King andKitchener’s Reflective Judgment Model and Perry’s model of intellectual and ethical development. Two of the frames captured levels of thinking: Garrison’s four-stage critical-thinking model and Bloom’s taxonomy of educational objectives. Of the 278 individual postings, 45.3% were at levels five through seven of the King and Kitchener model, 100% were at levels five through nine of the Perry model, 52.2% were at the two highest levels of the Garrison model, and 54.3% were at levels four through six in Bloom’s taxonomy. These results seem appropriate to the level of response expected of doctoral students. For each frame, the analysis resulted in additional findings. The study concludes that each frame has value and focuses attention on different aspects of the student’s thinking as evidenced in his/her posting to an online discussion; however, some frames are more difficult to use than others, which argues for specific training and/or tailoring the topic of discussions to address issues in a particular manner. Lastly, the question initiating each of the online discussions influenced the level of the responses from students. Each frame has the potential to illumine students’ online discussions, although using multiple frames may have more benefit than using any one frame exclusively.
TAKING E-MODERATING SKILLS TO THE NEXT LEVEL: REFLECTING ON THE DESIGN OF CONFERENCING ENVIRONMENTS
Authors: Ross Shelagh M. , Kukulska-Hulme Agnes , Chappel Helen , Joyce Brian
Published: March 2019

This paper reports an analysis of computer conference structures set up for a distance education course in which major components of the teaching and learning involve group discussions and collaboration via asynchronous text-based conferencing. As well as adopting traditional e-moderator roles, tutors were required to design appropriate online spaces and navigation routes for students. Tutors’ views concerning conference structures focussed on tensions between enabling easy access to conference areas, facilitating the successful running of activities, and addressing students’ subsequent needs for retrieval of conference material for assessment tasks. The geographically dispersed course tutors initially explored these issues in reflective online conversations. Comparisons were made between structures that were set up differently but all used for essentially the same tasks and purposes. Evidence from conference messages, from student feedback given in questionnaire and interview responses, as well as from students’ written assignments, provided insights into the impact such structures may have on the student learning experience. Students found conference areas for their own group easy to navigate, but they had concerns about managing the large number of messages; these concerns centred on the volume, threading, linking, length, and language of messages.
PREDICTING LEARNING FROM ASYNCHRONOUS ONLINE DISCUSSIONS
Authors: Wu Dezhi , Hiltz Starr Roxanne
Published: March 2019

Online discussions play an important role in student learning. Currently, asynchronous learning courses and some primarily face-to-face courses at New Jersey Institute of Technology require asynchronous online discussions. Does this requirement improve the students’ perceived learning? An exploratory study designed to investigate this issue was conducted in Spring 2002. The questionnaire drew responses to a post-course questionnaire from 116 students in two undergraduate courses and one graduate course. A set of items designed to measure perceived learning from online discussions formed a reliable, unidimensional index for this construct. The results indicate that online discussions do improve students’ perceived learning. Variations among instructors or courses are associated with differences in perceptions of student motivation, enjoyment, and learning from online discussion. Open-ended questions identified some student concerns about online discussions. The concluding section of this paper presents some implications for improving online discussions and for future research plans.
COST-EFFECTIVE DISTRIBUTED LEARNING WITH ELECTRONICS LABS
Authors: Campbell Olin , Bourne John R. , Mosterman Pieter J. , Nahvi Mahmood , Rassai Rassa , Brodersen Arthur J. , Dawant Martine
Published: March 2019

Online learners can study at convenient times and collaborate with others online, but usually can not come to physical labs. We investigated the use of simulated electronics laboratories to increase access and decrease trips to a physical lab. Students were assigned to either physical labs or to a combination of simulated and physical labs. Students using combined virtual and physical labs performed as well as those using only physical labs on both written and physical lab tests. This evidence supports the use of virtual labs to replace some physical labs, including the use of virtual labs for online learners.
SOLVING THE LABORATORY DILEMMA IN DISTANCE LEARNING GENERAL CHEMISTRY
Authors: Reeves Jimmy , Kimbrough Doris
Published: March 2019

Making a laboratory science course accessible to distance learners requires eliminating certain barriers. This paper describes one semester introductory chemistry courses for science and non-science majors that feature laboratory experiments that students can do at home, using materials readily available from local grocery and hardware stores. Courses using this approach have been offered successfully for several years at the University of Colorado at Denver, Cape Fear Community College and the University of North Carolina at Wilmington, and the laboratory experiences of the distance learners compares favorably with that of traditional students. This paper describes the important features of the distance learning courses, and provides assessment results that indicate the suitability of these experiments as replacement for traditional laboratories.

EXPERIMENTAL ONLINE CASE STUDY FOR A BREAKTHROUGH IN STUDENT ENGAGEMENT: FOCUS GROUP RESULTS
Authors: Theroux James , Carpenter Cari , Kilbane Clare
Published: March 2019

A new type of case study, called the real-time case (RTC), was produced in the fall of 2001 and distributed via the Internet to business classes at four universities in the US and Canada. The real-time case presented the story of one company's growth and development throughout a 14-week semester. A case writer stationed full-time at the subject company published case installments weekly on the Web, allowing students to view the company-building process as it happened. The 14-week coverage of RTC enabled students to study the subject company in unprecedented depth and detail. RTC's real-time interactivity allowed students to share their analyses and best thinking with the company leadership during the company’s decision-making process.A major objective in producing the case was to heighten student engagement with the case material. To evaluate whether this objective was achieved, a survey and a focus group discussion were conducted with one of the participating MBA classes. Results from the survey and the focus group showed a high degree of engagement, plus many other benefits from the new type of case study.
FACULTY SELF-STUDY RESEARCH PROJECT: EXAMINING THE ONLINE WORKLOAD
Authors: Thompson Melody M.
Published: March 2019

Concerns about faculty workload in the online environment are a reported deterrent to participation in online teaching. To date, such concerns have been based primarily on anecdotal evidence rather than empirical research. This paper describes a project in which six faculty members teaching courses through the Penn State World Campus conducted studies of the comparative workload in the online environment. Results of the studies indicated that faculty workload for teaching these online courses, as measured by time on task, was comparable to or somewhat less than that for face-to-face courses. However, a differential “chunking” of productive time contributed in some cases to a perception of increased workload. The success of the project suggests it is a replicable model for investigating various elements of the faculty experience in the online environment.
COMPARISON OF OUTCOMES ON LIKE EXAMS ADMINISTERED TO IN-RESIDENCE AND ASYNCHRONOUS DISTANCE-BASED PHARM.D. STUDENTS
Authors: Ragan Ronald E. , Kleoppel James W.
Published: March 2019

The purpose of this retrospective study was to compare the academic outcomes of distance-based students in the asynchronous non-traditional pathway with in-residence students in the traditional pathway on examples of like examinations in the Pharm.D. curriculum at the Kansas University School of Pharmacy. This study evaluated the commitment of assuring equivalent outcomes for students in non-traditional and traditional Pharm.D. pathways, as stipulated by the School of Pharmacy accrediting body, the American Council on Pharmaceutical Education (ACPE). Similar examinations were administered to both groups of students. Scores were evaluated using the Student t-Test and ANOVA. This study demonstrates that average test scores of distance-based students were equal to or higher than their counterpart in-residence students when tested on physical assessment content.
SCAFFOLDING COMPLEX TASKS BY OPEN ONLINE SUBMISSION: EMERGING PATTERNS AND PROFILES
Authors: Ronen Miky , Langley Dorothy
Published: March 2019

Students in higher-education courses are often confronted with complex tasks that require application and integration of newly gained knowledge. Different students require different types and amounts of instructional scaffolding for coping with such challenging tasks. The incorporation of asynchronous online elements into academic courses offers various ways of implementing traditional instructional scaffolding methods, as well as the ability to incorporate new strategies made feasible by this medium.This paper presents and discusses the potential and challenges of using open online submission of assignments via asynchronous networking as a strategy for providing differential scaffolding in the preparation of complex tasks (not as an alternative model for online peer collaboration).A pilot study, performed with five graduate education courses, showed that open online submission of assignments led to spontaneous, informal peer-evaluation, enabling students to learn from peer examples. The detailed analysis of students’ activity and their reflections has revealed four typical learner profileswith respect to open assignment submission, self-evaluation and characteristic benefit from peer work.
ONLINE LEARNING AND TIME-ON-TASK: IMPACT OF PROCTORED VS. UN-PROCTORED TESTING
Authors: Wellman Gregory S. , Marcinkiewicz Henryk
Published: March 2019

The purpose of this study was to evaluate the impact of proctored versus un-proctored testing on practice time and learning for a self-study, online course in medical terminology. Participants included 120 college students in a pharmacy curriculum. Subjects were randomized to one of three groups utilizing textbook with proctored assessment, online instruction with proctored assessment, or online instruction with un-proctored assessment. A pre-test and post-test was administered to all three groups to evaluate learning. Content page “hits” and practice quiz access was tracked for participants. Learning, as defined by pre/post-test change score, was greatest in the presence of proctored assessment (online and text) (p = 0.027). In addition, use of practice quizzes had a stronger relative correlation with learning (r = 0.401; p<0.001) when compared to content page “hits” (r = 0.257; p = 0.024). Online course content paired with meaningful time-on-task (e.g. practice quizzes) was most effective when paired with proctored assessment.

DIGITAL TEXT, DISTANCE EDUCATION AND ACADEMIC DISHONESTY: FACULTY AND ADMINISTRATOR PERCEPTIONS AND RESPONSES
Authors: Kelley Kimberly B. , Bonner Kimberly
Published: March 2019

This study examined administrator and faculty perceptions of the frequency and pervasiveness of student academic dishonesty, including their perceptions of the personal and contextual factors that affect whether a student is likely to engage in any form of academic dishonesty. One important contextual factorexamined in this study was the extent to which the respondents thought that using the Internet in a course, delivering a course via distance education, or the availability of digital text through the Internet impacted the prevalence, prevention, and detection of academic dishonesty.
THE EBB AND FLOW OF ONLINE DISCUSSIONS: WHAT BLOOM CAN TELL US ABOUT OUR STUDENTS’ CONVERSATIONS
Authors: Meyer Katrina A.
Published: March 2019

This study looks at online discussions within the context of a group endeavor and attempts to evaluate three assertions: 1) students in an online discussion proceed through higher levels of thinking; 2) Online conversations follow an “ebb and flow” pattern; 3) The level of the first posting to the discussion influences the level of subsequent postings. Postings were classified by the Bloom’s taxonomy of educational objectives and were graphed to help analyze the assertions. There was only modest support for the first assertion and better support for the second and third assertions. Analyzing online discussions as a group endeavor may well prove an interesting area of research for those interested in applying the existing body of literature and theory on group discussions in the face-to-face arena to the online environment. Researchers need to evaluate whether this literature is applicable to online discussions and what distinctions can legitimately be made between group discussions in the face-to-face or online mode.

ELECTRONIC SPACES AS AN ALTERNATIVE TO TRADITIONAL CLASSROOM DISCUSSION AND WRITING IN SECONDARY ENGLISH CLASSROOMS
Authors: Lee Sangmin
Published: March 2019

In most secondary school classrooms, teachers are still authoritative, central-figures. They talk and teach while students listen and passively receive what the teacher says. Regarding writing, the situation is similar. Students write only to the teacher, the person who grades their papers. In this environment, classroom dynamics are monologic and learning is limited to individuals. To establish a more constructivist learning environment, this study explored electronic spaces as alternatives to classroom dialogue and writing. This paper observed two 10th grade English classrooms (51 students) whoparticipated in an exploration of Lord of the Flies using an electronic discussion board through which they collaboratively constructed knowledge. In short, the discussion board facilitated both student-centered dialogues and an authentic writing environment, which promoted a dynamic learning community and healthy writer’s identity for the students. Three salient features of the discussion board activity will be explored to support this claim: a) the students’ use of questions and hypothetical/conditional sentences, b) the students’ interaction patterns, and c) the dialogic/progressive patterns of co-construction of knowledge on the discussion board.
ASSESSING STUDENT LEARNING WITH AUTOMATED TEXT PROCESSING TECHNIQUES
Authors: Wu Yi-fang Brook , Chen Xin
Published: March 2019

Research on distance learning and computer-aided grading has been developed in parallel. Little work has been done in the past to join the two areas to solve the problem of automated learning assessment in virtual classrooms. This paper presents a model for learning assessment using an automated text processing technique to analyze class messages with an emphasis on course topics produced in an online class. It is suggested that students should be evaluated on many dimensions, including the learning artifacts such as course work submitted and class participation. Taking all these grading criteria into consideration, we design a model which combines three grading factors: the quality of course work, the quantity of efforts, and the activeness of participation, for evaluating the performance of students in the class. These three main items are measured on the basis of keyword contribution, message length, and message count, and a score is derived from the class messages to evaluate students’ performance. An assessment model is then constructed from these three measures to compute a performance indicator score for each student. The experiment shows that there is a high correlation between the performance indicator scores and the actual grades assigned by instructors. The rank orders of students by performance indicator scores and by the actual grades are highly correlated as well. Evidence from the experiment shows that the computer grader can be a great supplementary teaching and grading tool for distance learning instructors.
RECIPROCITY ANALYSIS OF ONLINE LEARNING NETWORKS
Authors: Aviv Reuven , Erlich Zippy , Ravid Gilad
Published: March 2019

Asynchronous Learning Networks (ALNs) make the process of collaboration more transparent, because a transcript of conference messages can be used to assess individual roles and contributions and the collaborative process itself. This study considers three aspects of ALNs: the design; the quality of the resulting knowledge construction process; and cohesion, role and power network structures. The design is evaluated according to the Social Interdependence Theory of Cooperative Learning. The quality of the knowledge construction process is evaluated through Content Analysis; and the network structures are analyzed using Social Network Analysis of the response relations among participants during online discussions. In this research we analyze data from two three-month-long ALN academic university courses: a formal, structured, closed forum and an informal, non-structured, open forum. We found that in the structured ALN, the knowledge construction process reached a very high phase of critical thinkingand developed cohesive cliques. The students took on bridging and triggering roles, while the tutor had relatively little power. In the non-structured ALN, the knowledge construction process reached a low phase of cognitive activity; few cliques were constructed; most of the students took on the passive role of teacher-followers; and the tutor was at the center of activity. These differences are statistically significant. We conclude that a well-designed ALN develops significant, distinct cohesion, and role and power structures lead the knowledge construction process to high phases of critical thinking.
MEETING THE NEEDS OF NONTRADITIONAL RESPONDERS THROUGH SUCCESSFUL ONLINE COURSES IN BIOTERRORISM RESPONSE
Authors: Vignare Karen , Sener John
Published: March 2019

The Monroe County (NY) Health Alert Network (MCHAN) and the Rochester Institute of Technology (RIT) recently completed their second year of a Centers for Disease Control grant-funded project that offers a series of instructor-led asynchronous online learning courses. The courses are designed to enhance the workforce competencies of local and state health department staff and other nontraditional responders in planning for and responding to bioterrorism and other health emergencies. The project meets an important need for critical skills and knowledge training in this field and demonstrates how partnerships of higher education, government, and industry can deliver such training online. Contrary to the results of many e-learning initiatives, the vast majority (84%) of students involved in the program successfully completed the courses they started. Student and instructor evaluation surveys show high degrees of satisfaction and success; they also provide useful information on how to improve the courses. A critical element in the success of the courses was the employment of a program coordinator to manage course creation, instructor training, marketing, and registration. If one considers project costs relative tocompletion rates, this project has been highly cost effective despite the added cost of paying instructors. Overall, project results indicate that the asynchronous instructor-led online course model can be implemented successfully in many corporate and government e-learning initiatives.
Effects of Papaya Leaves Crude Extract on the Physicochemical and Sensory Characteristics of Marinated Chicken Meat
Authors: Rosman Rosliana , Ismail Normah
Published: March 2019

The purpose of this study was to investigate the effect of papaya leaves crude extract on the physicochemical properties of marinated chicken meat. Papaya leaves was extracted with sodium acetate (CH3COONa) buffer (pH 7.2) at room temperature. Protein concentration and activity of enzyme in the crude extract were determined by using UV-Spectrophotometer. The crude extract was mixed with marinated ingredients and then coated onto chicken meat which was subsequently kept for overnight in refrigerator at chill temperature. Protein concentration of the enzyme was identified as 166.36 μg/μl and enzyme activity was 1.28 CDU/ml. Results also showed that lightness (L*), cooking loss and shrinkage of the marinated chicken were higher than control. Redness (a*), yellowness (b*), protein content, water-holding capacity, shear force, and texture profile analysis were lower than control. Microstructure analysis showed that the chicken meat muscle was destructed in the presence of papaya crude extract. Sensory acceptability evaluation of marinated chicken which was carried out by using 9 point hedonic scale suggested that chicken meat treated with papaya crude extract gave significant effect on texture, juiciness, flavour and overall acceptability compared to commercial bromelain. Additionally, the use of papaya crude extract gave a significant effect on the physicochemical properties of marinated chicken.

Published: March 2019

In recent years, the number of different course books focused on school-age educare available for undergraduates in teacher education programs for primary school has increased. Thus studying what particular version of school-age educare is legitimized in this discursive practice and how this is done rhetorically becomes pertinent. This article examines and illuminates how this course literature – used at several universities in Sweden – stages a certain way of speaking about school-age educare and thereby may ascribe teachers and children specific subject positions. The study shows how recurrent ideological dilemmas are used as linguistic resources to manage some constantly present contradictions: school-age educare is supposed to be both democratic and child centered, as well as professionally planned and lead. The findings illuminate a homogenous depiction of how school-age educare is distinguished from traditional and formal schooling and thereby promoted as a unique but also necessary form of education. As a consequence, an ideal teacher is someone who is specialized in being actively passive and passively active, and an expert on children’s learning while children are considered experts on themselves and in the activities as well. That is, teacher’s professionalism in educare is tied to the skill of not being formal and school-like, but still being educational in a way that promotes politically-approved learning and development.
Cuerpo y música en la descripción de Sonora de Ignaz Pfefferkorn
Authors: Brenscheidt genannt Jost Diana
Published: March 2019

La presente contribución emplea un enfoque interdisciplinario que analiza una relación misional del siglo XVIII, ubicándola en la tradición de las historias naturales. Con ello indaga el lugar del cuerpo y de las prácticas performativas musicales de los naturales en la región noroeste de la Nueva España. Lo anterior se realiza estudiando la obra del misionero jesuita Ignaz Pfefferkorn, donde describe y clasifica los cuerpos indigenas, generalmente percibidos de manera positiva, para ponerlos en relación con el paradigma humoral, higienista y civilisatorio de la época, entendiendo al cuerpo como una categoría variable. Siguiendo a Foucault, se aborda el rol específico de la música y de las prácticas performativas musicales como parte del disciplinamiento del cuerpo en la misión, destacando su lugar dentro del sistema codificado del contacto cultural.

Environmental Realities: Evaluating Climate Change Coverage of Philippine Online News Media
Authors: Pacoma Marc Agon
Published: March 2019

Climate change is one of the most pressing issues at the present time, imposing great threats to human life and society. With issues surrounding climactic information, media seemed to play the most important role in addressing this problem. The inadequacy of researches on climactic coverage by media had motivated the researcher to embark on this exploration. This content analysis compared daily coverage of online news portals (Philippine Daily Inquirer, Manila Bulletin and Philippine Star) on climate change and climactic science-related issues from 2015-2016. The results indicated that there was a relative increase on climate change coverage by the media in a span of two years. Environmental frames, government sources, the Paris Agreement, the news section, and wired photos were the dominant themes that emerged during the coding process, which reflects and resonates similar findings of research inquiries on climate change coverage.

The process is carried out with data analysis techniques by performing 3 (three) aspects of the analysis systematically, namely data reduction, data display, and drawing conclusions. This study found that radio broadcasting in addition to air or broadcast transmission in the form of sound or sound also distributes broadcasts through live streaming or streaming podcasts on the internet (network) in the form of sound, text, images and videos.
Construction of synthetic carbonate plugs: A review and some recent developments
Authors: Arismendi Florez Jhonatan Jair , Ferrari Jean Vicente , Michelon Mateus , Ulsen Carina
Published: March 2019

Plugs are cylindrical rocks with known dimensions that are extracted typically from reservoir formations with representative mineralogical compounds, petrophysical properties and oilfield fluids. They are used in the laboratory to understand the behaviour of oil in reservoirs. One of their applications is to study the screening of chemicals, such as surfactants and polymers, for enhanced oil recovery research before being applied in the reservoir. Many of Brazil’s pre-salt basins are located in ultra-deep waters, and the high heterogeneities of its offshore carbonate reservoirs make the extraction of representative rock samples difficult, risky and expensive. The literature reports the construction of synthetic plug samples that reproduce rocks as an alternative and viable solution for this issue. However, there is a lack of publications that focus on the construction of representative carbonate plugs that considers both the mineralogical composition and petrophysics properties, such as porosity and permeability. In this work, the construction of synthetic plugs is studied, using a combination of published methodologies to achieve an alternative construction of synthetic carbonate plugs for laboratory scale studies. Using a procedure based on the use of pulverized rock matrices with known particle sizes, uniaxial compaction, and probable CaCO3 solubility control by changing temperature and pH, it was possible to obtain synthetic carbonate plugs with a similar mineralogy to the natural carbonate reservoir. However, further studies are necessary to obtain more controlled petrophysical properties of such samples.
The Periodic Table and Kinetics?

Mendeleev in his first publication ordered the chemical elements following an apparent periodicity of properties such as atomic volume and valence. The reactivity of the elements was only studied systematically many years later. To illustrate the systematic variation of kinetics across
the periodic table we compare water residence times for monoatomic ions in aqueous solution. A tremendous variation of ?H2O by over 20 orders of magnitude is found, ranging from ~10 ps to about 200 years. Apart from some small +2 and +3 cations, all main group elements have
very short residence times

Mechanisms driving cognitive improvements following nuclear receptor activation are poorly understood. The peroxisome proliferator–activated nuclear receptor alpha (PPARα) forms heterodimers with the nuclear retinoid X receptor (RXR). We report that PPARα mediates the improvement of hippocampal synaptic plasticity upon RXR activation in a transgenic mouse model with cognitive deficits. This improvement results from an increase in GluA1 subunit expression of the alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor, eliciting an AMPA response at the excitatory synapses. Associated with a two times higher PPARα expression in males than in females, we show that male, but not female, PPARα null mutants display impaired hippocampal long-term potentiation. Moreover, PPARα knockdown in the hippocampus of cognition-impaired mice compromises the beneficial effects of RXR activation on synaptic plasticity only in males. Furthermore, selective PPARα activation with pemafibrate improves synaptic plasticity in male cognition-impaired mice, but not in females. We conclude that striking sex differences in hippocampal synaptic plasticity are observed in mice, related to differences in PPARα expression levels.

Se analiza el discurso de posesión del presidente colombiano Juan Manuel Santos del 7 de agosto de 2014, desde la perspectiva de los estudios críticos del discurso, el cual fue difundido por distintos medios de comunicación. Se apropian categorías de los campos de la semiótica, la sociología y la ciencia política, para dar cuenta de las formas de semiotización a través de las cuales son estabilizados en el discurso político, los sistemas representacionales que fundamentan el régimen neoliberal. Se analizan unidades temáticas, diseños contextuales a través de marcadores temporales, formas de nominación, ejemplarización narrativa, reiteración, atribuciones, entre otras categorías semiótico-discursivas.
La construcción metafórica de la "exclusión" desde el trabajo social profesional
Authors: Matos-Silveira Rosana
Published: March 2019

El propósito de este trabajo consiste en dar a conocer el pensamiento profesional de un colectivo de trabajadores/as sociales españoles/as sobre el constructo ´exclusión social´ centrándose en la perspectiva metafórica. Para la comprensión de esta percepción fue fundamental como herramienta cualitativa de investigación la aplicación del grupo focal (focus group). Esta herramienta desde su alcance interactivo, propició una discusión fluida y el surgimiento de diversas y articuladas metáforas a la hora de construir y de-construir significados en torno a creencias y actitudes relacionados con el fenómeno estudiado. Resaltar que la Teoría de las Representaciones Sociales se presenta como mecanismo explicativo para analizar el papel que juegan estas representaciones en la dinámica cotidiana de la práctica profesional.
UNA APROXIMACIÓN DEL CORREO ELECTRÓNICO DESDE UNA PERSPECTIVA DIACRÓNICA

El objetivo de estudio es determinar las propiedades del correo electrónico como género discursivo, su configuración dentro de una comunidad definida de usuarios (SWALES, 1990) y su evolución en relación a la transformación de sus usos (MILLER, 1984). Nos interesa identificar los rasgos discursivos que se han mantenido estables en su uso y que nos legitiman a considerarlo un género discursivo particular dentro del discurso digital. Para ello, abordaremos una perspectiva diacrónica, en la que, a partir de una metodología cualitativa, combinamos el análisis de un corpus de mensajes de correo electrónico, producidos entre el año 2000 y 2015 y recogidos en el marco del PROYECTO CoDiCE, con los resultados de una encuesta sobre hábitos comunicativos en internet.

O Programa de Residência em Área Profissional da Saúde em Medicina Veterinária da Universidade Federal Rural do Pernambuco tem como parte do objetivo capacitar residentes Médicos Veterinários por meio do treinamento em serviço para atuação na saúde pública, nas áreas de vigilância em saúde. Dessa forma, o presente estudo objetivou descrever o método utilizado na formação teórica e prática dos residentes, previamente à inserção dos mesmos no Sistema Único de Saúde (SUS), destacando suas potencialidades e fragilidades. Antes do início das atividades na Secretaria de Vigilância em Saúde e no Núcleo de Apoio à Saúde da Família, foram oferecidas duas disciplinas utilizando-se metodologias ativas: Políticas Públicas em Saúde e Integração Ensino Serviço Comunidade. Ao final de cada disciplina foi solicitado aos residentes aprovados (100% dos residentes matriculados) que relatassem suas opiniões sobre as mesmas, elencando as potencialidades e as fragilidades. As potencialidades mais relatadas foram: uso de metodologias ativas como Aprendizagem Baseada em Problemas (ABP) e estudos de casos (77,8%), leitura de artigos e elaboração de resumos (27,8%) e esclarecimentos sobre a vigilância em saúde (22,2%). Em relação as fragilidades, os residentes relataram em maior porcentagem a leitura de muitos artigos em um único dia (61,1%), dificuldade em interpretar artigos com temas diferentes da área de atuação (22,2%) e muito tempo de vivência no SUS (16,7%). Conclui-se que a metodologia ativa apresenta pontos positivos e negativos, como relatado pelos residentes, porém o modelo favorece uma forma de ensino-aprendizagem necessária à implementação dos residentes médicos veterinários para atuação no SUS.

Afecções do aparelho respiratório inferior são rotineiras na clínica de pequenos animais e possuem diversas etiologias sendo necessária, portanto, precisão no momento da identificação dos agentes envolvidos, que acarretará em intervenções adequadas caso a caso.  O lavado broncoalveolar (LBA) constitui-se como importante meio diagnóstico que pode ser utilizado em animais com broncopneumonia que não respondem a terapia padrão. Apesar do LBA ser uma técnica simples, o mesmo não é rotineiramente utilizado na medicina veterinária. Desta forma, o presente trabalho vem destacar não somente a importância da realização do LBA na identificação dos microrganismos envolvidos e suas respectivas sensibilidades e resistências aos antibióticos, como também demonstrar a importância do diálogo com os tutores quanto a administração, conservação dos fármacos e até mesmo sobre a interrupção do tratamento sem recomendação veterinária.

A transmissão da artrite encefalite caprina pelo sêmen inviabiliza o uso de reprodutores soropositivos de alto valor genético. Como o vírus da artrite encefalite caprina (CAEV), é encontrado no sêmen na forma de RNA viral (vírus livre) ou DNA pró-viral dentro das células não espermáticas, possibilita que pesquisas com plantas com potencial antiviral sejam algo promissor para viabilizar o sêmen de reprodutores caprinos de grande valor zootécnico infectados. Diante disso, com essa revisão objetivou-se elucidar o potencial de fitocompostos, com comprovada ação antiviral, que poderiam vir a ser alvo de estudo para inativar o lentivírus caprino no sêmen. Inúmeras plantas de muitas famílias botânicas já foram estudadas para validação de efeito antiviral contra diversos vírus que acometem animais e humanos. Folhas, raízes, flores, e sementes demonstraram ao longo do tempo em sua constituição fitoquímica substâncias antivirais promissoras. De acordo com o tipo de planta, não apenas algumas partes dela, mas regiões inteiras da mesma são alvos das pesquisas por fitocompostos a ser usado como alternativa no combate as doenças virais. A base dos estudos nessa vertente são os metabólitos secundários, pois nas pesquisas têm apresentado compostos bioativos antivirais de alto potencial atuando nas diferentes fases do ciclo de desenvolvimento viral. Dessa forma, a biodiversidade da flora brasileira aliada à tendência de formar fitocompostos poderiam contribuir no avanço das pesquisas, a fim de encontrar uma alternativa de base natural, potencialmente eficaz, para eliminar os riscos de transmissão do CAEV pelo sêmen.
