Aplicación de alternativas tecnológicas para mejorar el proceso de elaboración y la preservación de queso fresco funcional de leche ovina adicionado con fibra dietaria de distintos orígenes
Authors:   , Peralta Reyes María Eugenia
Published: July 2019

Teniendo en cuenta la relación existente entre nutrición y salud, así como la demanda creciente de los consumidores a productos más saludables, en esta Tesis se trabajó en el desarrollo de queso fresco funcional con leche ovina adicionado con fibra dietaría de diferentes orígenes, en los cuales se aplicaron diferentes alternativas tecnológicas para lograr una mayor aceptabilidad por parte del consumidor, siempre contribuyendo a su salud y bienestar. En ese sentido, las estrategias utilizadas para la obtención de productos saludables pero sensorialmente más aceptados, fueron la homogeneización del queso fresco elaborado, la adición de diferentes tipos de fibras y la dosificación un bajo porcentaje de sal. En este trabajo se diseñaron quesos frescos con y sin homogeneizar, con y sin adición de sal y con el agregado de fibras de diferentes orígenes: fibra de bambú, fibra de trigo, inulina y psyllium. De este modo, se obtuvieron productos que además de aportar fibra a la dieta diaria y poseer valores de sodio bajo, presentan un mayor contenido de proteínas que los productos comerciales, que coincide con el hecho de que el contenido proteico en la leche de oveja es superior al de la leche de vaca. De todas las elaboraciones se determinó el rendimiento quesero, y los productos desarrollados fueron caracterizados a través de su composición centesimal y valor calórico. A su vez, se evaluó la microestructura y la reología de los diferentes quesos desarrollados, completando el estudio de los mismos con un análisis sensorial de aceptabilidad general, para determinar si las alternativas tecnológicas aplicadas influenciaron positivamente en la percepción del consumidor. Además, se realizó el seguimiento durante su almacenamiento congelado, en envases de polietileno y película semipermeable al oxígeno, evaluando pH, suero liberado, microestructura, textura y oxidación de lípidos. Se pudo concluir que es posible elaborar quesos frescos untables de leche ovina funcionales con inulina, fibra de trigo o fibra de bambú con características muy saludables desde el punto de vista nutricional. De igual modo, la adición de 0.3 % de sal, el proceso de homogeneizado y el almacenamiento congelado fueron alternativas tecnológicas adecuadas para elevar y preservar la calidad de los quesos frescos untables desarrollados.
El tiempo de la prisión
Authors:   , González Alvo Luis Gabriel
Published: July 2019

En este tesis se analiza la historia del triunfo del encierro por sobre las otras formas de castigo en las provincias de Córdoba, Santa Fe y Tucumán. Es el tiempo de la prisión, la cual desde temprano manifestó sus inconveniencias y peligros y, sin embargo, no se “vio” otro camino hacia la civilización y la modernidad punitiva. Identificar cuáles fueron las características de ese encierro triunfante es el hilo conductor a lo largo de casi un siglo de historia. Su nivel de imposición por sobre las demás penas fue cambiante según los años y, en ningún momento, se trató de un castigo uniforme e igual para todos sino que se focalizó un sector de la población y, al interior de ese sector, fue muy dispar según la condición judicial o la pertenencia a las minorías penales: mujeres, menores y “locos”. La construcción, administración y mantenimiento de espacios tradicionales, transicionales y novedosos jalonaron este recorrido por las reformas penitenciarias provinciales, que mostró avances y retrocesos.
Argentina y el MERCOSUR entre dos proyectos de integración regional: el ALCA y la UNASUR, 1989-2011
Authors:   , Jaquenod Alejandro M.
Published: July 2019

En este trabajo pretendemos analizar, desde la perspectiva argentina, el quiebre en el proceso de integración sudamericano comprendido entre los años 1989 y 2011. Identificamos un primer momento donde dicho proceso se basó en las premisas del Consenso de Washington, y un segundo momento pretendidamente neodesarrollista impulsado por un Brasil posicionándose como potencia regional. En relación con las hipótesis que fundamentan el quiebre mencionado en los cambios de influencia relativa de EE.UU. y Brasil en la región tras 2001, sostenemos que para la comprensión de dicho quiebre, junto con el abandono del proyecto del ALCA y la profundización de la UNASUR es necesario incorporar el análisis de los conflictos sociales desatados en la región, y particularmente en Argentina. Sostenemos que la oposición brasileña a la hegemonía estadounidense en la región ya se encontraba presente en la década del ’90, pero sólo pudo ser materializada con el apoyo de Argentina, su mayor socio regional. Entendemos que este apoyo puede explicarse (entre otros factores) como consecuencia de la conflictividad social desatada en nuestro país tras las jornadas de diciembre de 2001. En este sentido, sostenemos que el realineamiento argentino en el contexto internacional, privilegiando las relaciones con los vecinos latinoamericanos por sobre las relaciones con EE.UU., significó una respuesta, entre otras, del gobierno nacional a la conflictividad social mencionada. Observamos que de no haberse dado este realineamiento difícilmente podrían haberse materializado las alternativas de integración propuestas por Brasil para la región. Es por eso que consideramos de gran importancia avanzar en el análisis de la relación entre las estrategias de política exterior de los Estados y la conflictividad social interna de los mismos.
La argumentación jurídica en las sentencias judiciales
Authors:   , Negri Nicolás Jorge
Published: July 2019

La tesis sostiene la necesidad de implementar la teoría de la argumentación jurídica del profesor español Manuel Atienza, como modelo metodológico, para justificar las sentencias judiciales en materia de cuantificación de los daños a la persona, de acuerdo con las exigencias del art. 3 del Código Civil y Comercial argentino y de la doctrina emanada de la Corte Suprema de Justicia de la Nación. El estudio de sus precedentes, en los que descalificaba los fallos de los tribunales del país por déficits de fundamentación, con base en la doctrina pretoriana de la arbitrariedad de sentencias, es el trabajo de campo de esta tesis, limitado al análisis de los fallos dictados desde el año 1983, con la vuelta de la democracia, hasta el año 2015, y, específicamente, a los supuestos de cuantificación del llamado “valor vida” e “incapacidad” psicofísica permanente.
Adequate Yearly Progress in Small Rural Schools and Rural Low-Income Schools
Authors: Farmer Thomas W. , Leung Man-Chi , Banks Jonathan , Schaefer Victoria , Andrews Bruce , Murray Robert Allen
Published: July 2019

Adequate yearly progress (AYP) on No Child Left Behind criteria was examined for a randomly selected sample of districts that qualify for the Rural Education Achievement Program (REAP). The sample involved 10% of districts that were eligible for the Small Rural Schools Achievement (SRSA) program and 10% that were eligible for the Rural and Low-income Schools (RLIS) program. Based on district reports, nearly 80% of SRSA schools made AYP, 11% failed, and 11% did not have adequate data. For schools in the RLIS program, districts reported that 65% made AYP, 29% failed, and 6% did not report adequate data. The SRSA and RLIS samples had different patterns for the categories of students that did not make AYP. Also, SRSA and RLIS districts were differentially distributed across the United States. Implications for interventions are discussed.
The Professional Development Needs of Rural High School Principals
Authors: Salazar Pamela S.
Published: July 2019

The increased emphasis on standards-based school accountability since the passage of the No Child Left Behind Act of 2001 is focusing critical attention on the professional development of school principals and their ability to meet the challenges of improving student outcomes. While rural school districts are dealing with many of the same issues facing urban districts, there are unique challenges that rural school principals face. However, effective professional development that addresses the unique needs of rural school leaders can build essential leadership capacity that supports school success. This article discusses the results of a study on the professional development needs of rural high school principals for school improvement. These findings provide direction for the development of professional development activities that will enhance the leadership skills that principals need to guide school reform and reach higher standards of student achievement.
A Case Study:
Authors: Horst Marilyn Dishman , Martin Barbara N.
Published: July 2019

The purpose of this study was to examine the perceived effectiveness of leadership in a Missouri rural K-8 school with a high incidence of poverty that consistently met federal and state accountability mandates. The concepts of accountability as measured by student achievement, the unique educational needs of children from poverty, and the challenges of the rural school location were viewed through the lens of leadership. Ten practices of leadership that lead to consistent student achievement were suggested. They include integrity and courage, focus and vision, expectations and data evaluation, resources and empowerment, role modeling, and collaboration. Implications of this study could impact mentoring programs to support beginning and practicing administrators, leadership training in schools of education and state leadership programs, programs and instruction designed for children from poverty, and considerations of the monetary and educational cost of consolidation.

There is a dearth of studies in science education that are both comprehensive and focused on rural schools. Thus, this brief is in the form of a research report on the impact of an externally funded, five-year professional development project. The project involved approximately 1500 teachers on the student achievement of approximately 20,000 K-6 students in 36 small, rural Midwest school districts. - Larry G. Enochs, Research Column Editor
Exploring Rural Contexts with Digital Storytelling
Authors: Wake Donna G.
Published: July 2019

This article describes rural middle school students’ exploration of their identity and their rural contexts through the vehicle of digital storytelling. Participants included 40 7th and 40 9th grade students at two rural schools in the Southeast United States. Students worked in shared writing groups to create digital stories expressing their views on teen life in a small, rural town. The resultant stories were analyzed using comparative grounded theory yielding some themes which may be posited as unique to a rural population while other themes were typical of the developmental age regardless of geographical context. Study findings indicate that the rural nature of the participants’ communities had a significant impact on their identity formation and understanding of community. This study supports students’ use of technology to promote exploration of identity within geographic and sociological settings.
Multiple Points of Contact: Promoting Rural Postsecondary Preparation through School-Community Partnerships
Authors: Alleman Nathan F. , Holly Neal L.
Published: July 2019

Formal and informal partnerships between rural schools and their communities can provide a wide range of supports for all students, but particularly those from low-income families. In this analysis of six small rural school districts in Virginia we show how the broad participation of community groups and individuals supports academic achievement as well as preparation and aspirations for postsecondary education. Results demonstrate that school-community partnerships provide multiple points of contact for students that buttress the efforts of school personnel by extended educational opportunities outside the classroom and by meeting the needs of low-income students when parents and teachers are unable to do so.

Las mujeres españolas y la conservación del status: el recurso de las instituciones cristianas
Authors: Puertas Porras Elizabeth , Maldonado Héctor
Published: July 2019

El presente artículo constituye una primera aproximación a la realidad que debieron enfrentar las mujeres españolas establecidas en el territorio peruano durante las últimas décadas del siglo XVI y el transcurso del siglo XVII. Su caso es significativo porque ellas cumplieron la tarea de conservar y transmitir las costumbres y valores propios de lo occidental hispano que se buscaban generalizar en la sociedad colonial en formación. Esta aproximación al tema permitirá concluir que la proximidad a instituciones y formas de ordenamiento derivadas del cristianismo católico fue empleada por mujeres provenientes de la tradición occidental como el medio más idóneo para conservar las posiciones que la complejidad del medio indiano les había permitido adquirir.

Finding the Remnants of the Milky Way's Last Neutron Star Mergers
Authors: Wu Meng-Ru , Banerjee Projjwal , Metzger Brian D. , Martínez-Pinedo Gabriel , Aramaki Tsuguo , Burns Eric , Hailey Charles J. , Barnes Jennifer , Karagiorgi Georgia
Published: July 2019

The discovery of a binary neutron star merger (NSM) through both its gravitational wave and electromagnetic emission has revealed these events to be key sites of r-process nucleosynthesis. Here, we evaluate the prospects of finding the remnants of Galactic NSMs by detecting the gamma-ray decay lines from their radioactive r-process ejecta. We find that 126Sn, which has several lines in the energy range 415–695 keV and resides close to the second r-process peak, is the most promising isotope, because of its half-life t
1/2 = 2.30(14) × 105 yr being comparable to the ages of recent NSMs. Using a Monte Carlo procedure, we predict that multiple remnants are detectable as individual sources by next-generation γ-ray telescopes which achieve sub-MeV line sensitivities of ∼10−8–10−6
γ cm−2 s−1. However, given the unknown locations of the remnants, the most promising search strategy is a systematic survey of the Galactic plane and bulge extending to high Galactic latitudes. Individual known supernova remnants which may be misclassified NSM remnants could also be targeted, especially those located outside the Galactic plane. Detection of a moderate sample of Galactic NSM remnants would provide important clues to unresolved issues such as the production of actinides in NSMs, properties of merging NS binaries, and even help distinguish them from rare supernovae as current Galactic r-process sources. We also investigate the diffuse flux from longer-lived nuclei (e.g., 182Hf) that could in principle trace the Galactic spatial distribution of NSMs over longer timescales, but find that the detection of the diffuse flux appears challenging even with next-generation telescopes.
Unusual Plasma and Particle Signatures at Mars and STEREO-A Related to CME–CME Interaction

On 2017 July 25 a multistep Forbush decrease (FD) with a remarkable total amplitude of more than 15% was observed by Mars Science Laboratory/Radiation Assessment Detector at Mars. We find that these particle signatures are related to very pronounced plasma and magnetic field signatures detected in situ by STEREO-A on 2017 July 24, with a higher-than-average total magnetic field strength reaching more than 60 nT. In the observed time period STEREO-A was at a relatively small longitudinal separation (46°) to Mars, and both were located at the back side of the Sun as viewed from Earth. We analyze a number of multispacecraft and multi-instrument (both in situ and remote-sensing) observations and employ modeling to understand these signatures. We find that the solar sources are two coronal mass ejections (CMEs) that erupted on 2017 July 23 from the same source region on the back side of the Sun as viewed from Earth. Moreover, we find that the two CMEs interact nonuniformly, inhibiting the expansion of one of the CMEs in the STEREO-A direction, whereas allowing it to expand more freely in the Mars direction. The interaction of the two CMEs with the ambient solar wind adds up to the complexity of the event, resulting in a long, substructured interplanetary disturbance at Mars, where different substructures correspond to different steps of the FD, adding up to a globally large-amplitude FD.
The TRGB Distance to the Second Galaxy “Missing Dark Matter”: Evidence for Two Groups of Galaxies at 13.5 and 19 Mpc in the Line of Sight of NGC 1052
Authors: Monelli Matteo , Trujillo Ignacio
Published: July 2019

A second galaxy “missing dark matter” (NGC 1052-DF4) has been reported recently. Here we show, using the location of the tip of the red giant branch (TRGB), that the distance to this galaxy is 14.2 ± 0.7 Mpc. This locates the galaxy 6 Mpc closer than previously determined. We also analyze the distances to the brightest galaxies in the field of view of NGC 1052. We find that this field is populated by two groups of galaxies in projection: one dominated by NGC 1052 and NGC 1047 at ∼19 Mpc, and another group containing NGC 1042 and NGC 1035 (as well as [KKS2000]04 and NGC 1052-DF4) at ∼13.5 Mpc. At a distance of 13.5 Mpc the globular clusters of NGC 1052-DF4 have the same properties as globular clusters in the Milky Way and other dwarf galaxies.
Spectrum in Kinetic Alfvén Wave Turbulence: Implications for the Solar Wind
Authors: David Vincent , Galtier Sébastien
Published: July 2019

The nature of solar wind turbulence at large scale is rather well understood in the theoretical framework of magnetohydrodynamics. The situation is quite different at subproton scales where the magnetic energy spectrum measured by different spacecraft does not fit with the classical turbulence predictions: a power-law index close to −8/3 is generally reported, which is far from the predictions of strong and wave turbulence, −7/3 and −5/2, respectively. This discrepancy is considered as a major problem for solar wind turbulence. Here, we show with a nonlinear diffusion model of weak kinetic Alfvén wave turbulence where the cascade is driven by local triadic interactions that a magnetic spectrum with a power-law index of −8/3 can emerge. This scaling corresponds to a self-similar solution of the second kind with a front propagation following the law k

f
 ∼ (t
*−t)−3/4, with t < t
*. This solution appears when we relax the implicit assumption of stationarity generally made in turbulence. The agreement between the theory and observations can be interpreted as an evidence of the nonstationarity of solar wind turbulence at subproton scales.
Effect of plant protection on assemblages of carabid beetles (Coleoptera, Carabidae) in beetroot crops in four-year rotation
Authors: Kosewska Agnieszka , Nijak Katarzyna , Nietupski Mariusz , Kędzior Renata
Published: July 2019

Ground beetles (Col., Carabidae) are common predators in agrocenoses. A number of plant pests occurring on arable fields become their feed. Therefore, they contribute to a natural reduction of the occurrence of pests. In addition, they are well-known bioindicators used, among others to determine the state of the habitats and the impact of human activity on entomofauna. In the fields, the use of chemical plant protection products is a very controversial activity. The aim of the study was to investigate assemblages of ground beetles occupying conventional and organic sugar beetroot crops. Therefore, to determine the impact of the application of pesticides on the assemblages of these useful beetles was made.

The study was conducted at the Agricultural Experimental Station in Winna Góra near Środa Wielkopolska in Poland from May till September of 2004, 2008, 2012 and 2016. The experiment was carried out in the field with organic crop of sugar beet, and in the crop, for which an integrated plant protection programme was planned. The area of each field was 0.5 ha. Modified Barber traps were used to catch insects. On each of the selected fields 10 pitfalls were set up, which were emptied every 14 days.

Within 4 years of the study a total of 11865 specimens belonging to 52 ground beetle species were recorded. 5582 specimens belonging to 50 species and 6283 specimens belonging to 46 species were caught in the fields under chemical protection and organic, respectively. On a multiannual scale, there were no statistically significant differences in the number of individuals and species of Carabidae on conventional and organic fields. Fluctuation in ground beetles abundance and species richness were observed dependent on the year of study but not of the treatment. Harpalus rufipes was the most represented species in all fields.

The main conclusion is that using chemical plant protection on a multiannual scale does not adversely affect the number and species richness of ground beetles.
Théâtre et récit : l’exemple des pièces monologuées contemporaines
Authors: Petitjean André
Published: July 2019

Depuis quelques décennies, on assiste à une véritable vogue de la parole solitaire au théâtre (monologues ou soliloques) sous la forme d’un personnage, seul en scène, qui parle et raconte. Ces longues coulées verbales ont pour effet de remettre en cause les grands principes des pièces dramatiques (unicité de l’intrigue, progression ordonnée et finalisée des actions, développement temporel chronologique, causalité explicite des enchainements). C’est ainsi que dans un premier temps, je montrerai en quoi ces textes sont de véritables récits, car la fable, proche en cela des fictions romanesques, n’est plus soumise au développement temporel strictement chronologique. Dans un second temps, on verra que la solitude du personnage n’est pas forcément antidramatique puisque ces monologues sont très polyphoniques en faisant advenir de nombreux personnages et c’est là un indice du processus de romanisation que connait le théâtre depuis plusieurs années.
Récits sériels exploratoires
Authors: Boni Marta , Martinez Camille
Published: July 2019

Partant d’une approche pragmatique de la réception qui considère la série télévisée comme processus et expérience exploratoire d’un espace diégétique pluridirectionnel, cet article allie analyse esthétique et narratologique en comparant les séries télévisées à des mondes fictionnels. À travers divers exemples de programmes des années 1990 à aujourd’hui, l’objectif est de penser les séries comme des expériences de construction de mondes et de comprendre les mécanismes de leur pouvoir immersif sur le long terme. L’espace, conçu en tant que monde ou territoire diégétique, permettra de compléter les méthodes d’analyse des séries télévisées présentant le temps comme moteur narratif principal et s’appuiera sur les théories spatiales des études cinématographiques et médiatiques.
De la narratologie à la narrativité, et retour
Authors: Bertrand Denis
Published: July 2019

Surprise dans le monde des greimassiens en 2014 : voici la narratologie de retour, et en force ! De grands congrès internationaux, réunissant des universités américaines et européennes, sont organisés et se consacrent à l’étude des « fabuleux pouvoirs du récit ». L’ère du storytelling se répand, assurant le succès de l’ouvrage de C. Salmon bien au-delà des frontières de l’université. Or, parmi les références théoriques de ce mouvement de recherche, pour l’essentiel issues du cognitivisme anglo-saxon, pas la moindre allusion à la « sémiotique narrative et discursive ». C’est pourtant sous ce titre que J. Courtés, alors assistant d’A. J. Greimas à l’École de hautes études en sciences sociales, publiait en 1976 chez Hachette un livre d’initiation à la sémiotique. Et dix ans auparavant, dès 1966, le schéma actantiel avait fait son apparition dans Sémantique structurale l’ouvrage fondateur d’A. J. Greimas : la formalisation de la grammaire narrative et son développement en syntaxe modale allaient devenir un des titres de gloire de cette sémiotique. C’est alors que la narrativité, outrepassant les frontières de la narratologie, devait faire son entrée dans les sciences humaines et sociales. Et voici qu’elle semblait oubliée. Que s’était-il donc passé ? Ou plutôt, où était passée la théorie greimassienne ? Notre propos est ici de faire le point sur cette histoire conceptuelle et de la mettre en perspective. Et nous le ferons en évoquant, en fin de parcours, la filiation descendante de cette théorie, à travers quelques voies sémiotiques qu’elle a enfantées. Non pour en présenter les labyrinthiques conceptualisations mais pour suggérer leurs apports respectifs à une réflexion renouvelée sur le récit.
Note on the Application of Intuitionistic Fuzzy TOPSIS Model for Dealing With Dependent Attributes
Authors: Aikhuele Daniel Osezua
Published: July 2019

In this article, the effectiveness of the intuitionistic fuzzy TOPSIS model (IF-TOPSISEF) is tested for addressing, capturing, and resolving the effect of correlation between attributes, otherwise called the dependency of attributes. This was achieved by using several normalization methods in the implementation of the IF-TOPSISEF model. Furthermore, the result of the computation is compared with the one obtained when the normalization methods are implemented using a traditional TOPSIS model. The study contributes and extends the state of the art in TOPSIS method study, by addressing, capturing and resolving the effect of correlation between attributes otherwise called dependency of attributes.

Authors: Klepac Goran , Kopal Robert , Mrsic Leo
Published: July 2019

Early warning systems are made with the purpose to efficiently recognize deviant and potentially dangerous trends related to company business as early as possible. The Big Data environment gives new opportunities and new approaches in analytical processes. There are numerous ways how to set up early warning systems within a company. The Big Data environment forces companies to apply new ways of thinking and use new disposable data sources. This article gives a novel concept for an early warning system design within a company, which is applicable in different industries. The core of the proposed framework is a hybrid fuzzy expert system which can contain a variety of data mining predictive models responsible for some specific areas as addition to traditional rule blocks. It can also include social network analysis metrics based on linguistic variables and incorporated within the rule blocks. As a part of this framework, SNA methods are also explained and introduced as powerful and unique tool to be used in modern early warning systems.
MHLM Majority Voting Based Hybrid Learning Model for Multi-Document Summarization

Text summarization from multiple documents is an active research area in the current scenario as the data in the World Wide Web (WWW) is found in abundance. The text summarization process is time-consuming and hectic for the users to retrieve the relevant contents from this mass collection of the data. Numerous techniques have been proposed to provide the relevant information to the users in the form of the summary. Accordingly, this article presents the majority voting based hybrid learning model (MHLM) for multi-document summarization. First, the multiple documents are subjected to pre-processing, and the features, such as title-based, sentence length, numerical data and TF-IDF features are extracted for all the individual sentences of the document. Then, the feature set is sent to the proposed MHLM classifier, which includes the Support Vector Machine (SVM), K-Nearest Neighbors (KNN), and Neural Network (NN) classifiers for evaluating the significance of the sentences present in the document. These classifiers provide the significance scores based on four features extracted from the sentences in the document. Then, the majority voting model decides the significant texts based on the significance scores and develops the summary for the user and thereby, reduces the redundancy, increasing the quality of the summary similar to the original document. The experiment performed with the DUC 2002 data set is used to analyze the effectiveness of the proposed MHLM that attains the precision and recall at a rate of 0.94, f-measure at a rate of 0.93, and ROUGE-1 at a rate of 0.6324.
Uncovering the Enablers, Benefits, Opportunities and Risks for Digital Open Government (DOG)
Authors: Naeem Muhammad
Published: July 2019

The systematic review approach has been used to collect, examine, interpret, and synthesize research regarding enablers, challenges, opportunities, risks, and the usefulness of open government. The current review adopted the meta-synthesis approach to conduct the systematic review on 61 selected research papers. The study has covered the enablers for such initiatives and how governments of various countries can achieve open government benefits like lower level of corruption, higher level of public awareness and education, high level of transparency, more democratic control, improve efficiency and effectiveness of public services, and improve public services. The author has extracted various risks and challenges that obstruct open government efforts from getting their full potential. The study is helpful for policymakers of those countries who are planning to implement an open government system in their countries. However, a cooperation bias is one of the most considerable limitations in research studies that are included in this systematic literature review.
Prevalence of depression in people living with HIV and AIDS at the Kalafong Provincial Tertiary Hospital Antiretroviral Clinic
Authors: Van Coppenhagen Brett , Duvenage Helene S.
Published: July 2019

Background: Compared to the general population, there is an increased prevalence of depression in people living with HIV and AIDS (PLWHA). The combination of these two common illnesses has profound consequences on the patient and on the healthcare system.Objective: This study determined the prevalence of depressive symptomatology in PLWHA attending the Kalafong Hospital ARV Clinic. The study also established if the patients received definitive treatment for unipolar depression.Methods: A cross-sectional, descriptive study was carried out on 622 adult patients, aged 18 years or older. A brief rating scale for depression, the Centre for Epidemiological Study Depression Scale (CES-D) was administered to participants. The CES-D is a 20-item self-rating scale that assesses current levels of depression as per DSM-IV criteria. The traditional score of 16 and above was used to define a case of depression.Results: The prevalence of depression according to CES-D scale was 53.8%. The study found that none of the 622 patients ever received definitive treatment for depression. A lower CD4 count is associated with more depressive symptomatology, most significantly in patients with a CD4 count of 50 or less.Conclusions: Depressive symptomatology was highly prevalent in the study patients. Despite the high prevalence, none of the study sample patients were treated for clinical depression. The findings reflect the importance of evaluating for depression in PLWHA, especially in high-risk groups such as patients presenting for their initiation visit or patients with a CD4 count of 50 or less. Depression remains under-recognised and under-treated in PLWHA.

Abstract. When quantifying temperature changes induced by deforestation (e.g., cooling in high latitudes, warming in low latitudes), satellite data, in situ observations, and climate models differ concerning the height at which the temperature is typically measured/simulated. In this study the effects of deforestation on surface temperature, near-surface air temperature, and lower atmospheric temperature are compared by analyzing the biogeophysical temperature effects of large-scale deforestation in the Max Planck Institute Earth System Model (MPI-ESM) separately for local effects (which are only apparent at the location of deforestation) and nonlocal effects (which are also apparent elsewhere). While the nonlocal effects (cooling in most regions) influence the temperature of the surface and lowest atmospheric layer equally, the local effects (warming in the tropics but a cooling in the higher latitudes) mainly affect the temperature of the surface.
In agreement with observation-based studies, the local effects on surface and near-surface air temperature respond differently in the MPI-ESM, both concerning the magnitude of local temperature changes and the latitude at which the local deforestation effects turn from a cooling to a warming (at 45–55∘ N for surface temperature and around 35∘ N for near-surface air temperature). Subsequently, our single-model results are compared to model data from multiple climate models from the Climate Model Intercomparison Project (CMIP5). This inter-model comparison shows that in the northern midlatitudes, both concerning the summer warming and winter cooling, near-surface air temperature is affected by the local effects only about half as strongly as surface temperature. This study shows that the choice of temperature variable has a considerable effect on the observed and simulated temperature change. Studies about the biogeophysical effects of deforestation must carefully choose which temperature to consider.
Gifts and Ghosts: A Derridean Reading of Theravada Communities
Authors: Yeng Sokthan
Published: July 2019

Because Europeans have shaped scholarly discourse about Southeast Asia and Buddhism, movement away from understanding “pure” Theravada Buddhism through religious and philosophical doctrine was a technique to decenter Western readings and shows how practitioners shaped their own beliefs. Stanley Tambiah called for academics to pay more attention to common beliefs of laypeople and everyday practices of monks. This, in turn, placed anthropologists at the center of collecting knowledge about Theravada Buddhism. Yet French philosophers continued, through their theories, to influence the structure of anthropological analysis of Theravada cultures, particular through gift exchanges. In this paper, I will explore ways Derrida’s theories of gifts and ghosts can add to anthropological studies of Southeast Asian communities while also helping to recover philosophical and ethical components of Theravada practices.
Dinamični občutek doma: prostorsko-časovni vidiki mobilnosti mladih Tokijčanov
Authors: IKALOVIĆ Vedrana , CHIESI Leonardo
Published: July 2019

V visoko industrializiranih in institucionaliziranih družbah, ki stremijo k čim večji učinkovitosti, morajo biti posameznikove dejavnosti usklajene z dnevnim ritmom mesta. Kot prostorsko in institucionalno okolje se mesto ljudem vsiljuje in vpliva na stopnjo njihove navezanosti na kraj, s tem pa posledično spreminja njihov občutek doma. To je najopaznejše v današnjih mestih, kjer je vsakdanje življenje zelo dinamično in se počitek pogosto odvija zunaj prebivališča (tj. na poti). S proučevanjem prostorsko- časovnih vidikov mobilnosti mladih Tokijčanov avtorja v članku analizirata, kako mesto vpliva na njihov občutek doma in stopnjo navezanosti na fizično okolje. Njune ugotovitve razkrivajo dinamičen občutek doma, pri čemer so poti pomembnejše od korenin, navezanost pa ni omejena samo na en kraj, ampak je razumljena bolj kot navezanost na časovno-prostorske odnose, ki jih ustvarjajo ljudje in ustanove s svojimi dejavnostmi.
Die isolierte Fraktion. Zwischenreaktionen, Zwischenrufe und die AfD im Baden-Württembergischen Landtag
Authors: Vögele Catharina , Thoms Claudia
Published: July 2019

How do the members of parliament use hecklings and other intermediate reactions in the Baden-Württemberg state parliament? Does the AfD as a new party in parliament differ from the other political groups? An automatic analysis of all interruptive actions recorded in the plenary protocols of the current and the previous legislative period as well as a manual content analysis of the hecklings used in 20 current debates (ten debates per legislative period) shows that the use of hecklings as well as other interruptive actions like applause or laughter mirrors the conflict between government and opposition parties . In the current legislative period, the AfD falls out of the ordinary in that the party is isolated from all other political groups by various means . For example, the other parties avoid applauding for AfD speakers and criticize them sharply through hecklings . The AfD and its members of parliament also distance themselves from the other parties by heckling and laughing maliciously about them . Thus, we can identify a clear polarization between the AfD and the other parties in the federal state parliament in Baden-Württemberg .
Der Eigenvorsorgebeitrag als Alternative zur beamtenrechtsähnlichen Versorgung für Abgeordnete. Zu den Ergebnissen der Kommission im Baden-Württembergischen Landtag
Authors: Tremmel Jörg
Published: July 2019

In 2018 the state parliament of Baden-Württemberg installed a commission of experts to inspect the existing retirement income system of its parliamentarians (Altersversorgung des Abgeordneten) . The commission report prompts a comparison between the existing retirement income system in Baden-Württemberg and a reflection on alternatives in other German states . Due to political, legal and economic reasons, one should opt against the system of civil servants-like pension schemes for members of parliament . Of all the alternatives, the system of a private pension contribution is most likely to reconcile the interests of all those involved . In order to do justice to the importance of the office and to secure sufficient retirement benefits, the amount of the contribution should be 2,000 Euro per month in the state parliaments and 2,500 Euro per month in the Bundestag .
