Authors: Freeman-Gibb Laurie , Jones Beverley , Rehman Selina , Ragier Janet
Published: June 2017

Background:

Ten years ago, nursing education in Ontario, Canada, changed when entry to practice and licensure became a bachelor's of science in nursing (BScN) for RNs. This article presents the initial results of an ongoing 5-year longitudinal study on undergraduate students' satisfaction within a collaborative BScN program and predictors of satisfaction with their nursing education.

Method:

BScN nursing students from one group of collaborative sites participated in a survey pertaining to satisfaction with their program. Data were collected via paper and pen or online.

Results:

Initial data found that students were satisfied or strongly satisfied with their collaborative nursing education (
M
±
SD
= 183.9 ± 32.7). However, any type of conflict had a significant negative relationship with satisfaction in all domains. No other significant predictors of satisfaction were uncovered.

Conclusion:

Overall, students were very satisfied with a collaborative model of baccalaureate nursing education. Conflict of any type decreases satisfaction within all domains of nursing education. [

Authors: Hlinka Josef , Lasek Stanislav , Branzovsky Jan
Published: June 2017

This paper is focused on prediction of nitinol stents lifetime. Stents have been tested before and after mechanical loading. Corrosion tests of mechanically loaded specimens indicated impairment of corrosion resistance and SEM observation confirmed presence of micro cracks in surface oxide layer created during heat treatment. Electrochemical impedance spectroscopy and potentiodynamic polarization in physiological solution was used for these particular experiments. Corrosion rate and other parameters have been used for calculation of released nickel ions weight and prediction of application lifetime.
Combination Criterion for Multiple Laminar Flaws in Steel Components
Authors: Lacroix Valéry , Mareš Vratislav , Strnadel Bohumír , Hasegawa Kunio
Published: June 2017

A laminar flaw is a planar subsurface flaw parallel to the rolling direction of the plate, where the applied stress is typically parallel to the rolling direction. The laminar flaw oriented within 10 degree of a plane parallel to the component surface is defined as a laminar flaw, in accordance with the definition of the American Society of Mechanical Engineers (ASME) Boiler & Pressure Vessel (B&PV) Code Section XI. The ASME Code provides combination criterion for multiple laminar flaws. If there are two or more laminations, these laminations are projected to a single plane and, if the separation distance of the projected laminations is less than or equal to 25.4 mm, the laminations shall be combined into a single large laminar flaw in the assessment. The combination criterion was established on the basis of the non-destructive examination capabilities in the 1970’s. However, this methodology did not consider the offset distance of the laminations nor the mechanical interaction between the flaws. Therefore that combination methodology is not suited in case of a large number of laminar flaws. This may occur e.g. in case of hydrogen flaking in steel forging components. Actually, when multiple discrete laminar flaws are close to each other, interaction between the flaws has to be taken into account and these flaws shall be combined to a single laminar flaw for assessment. Stress intensity factor interactions for inclined laminar flaws were analyzed in the frame of hydrogen flaking issue in reactor pressure vessels of Doel 3 and Tihange 2 Belgian nuclear power plants. Based on the mechanical interaction between flaws, new combination criterion was developed and was presented in this paper.
Fatigue Crack Growth Simulation Using S-Version FEM: Application to Interacting Subsurface Cracks
Authors: Takahashi Akiyuki , Suzuki Ayaka , Kikuchi Masanori
Published: June 2017

In this paper, fatigue crack growth simulation of interacting subsurface cracks using the s-version finite element method (SFEM) is presented. In order to evaluate the accuracy and reliability of the proximity rules published by the ASME, during the fatigue crack growth simulations, the subsurface cracks are approximated to either a single elliptical crack or semi-elliptical surface crack in accordance with the proximity rules. Then, the proximity rules are slightly modified for improving the accuracy and reliability. The results of crack depth evolution calculated by the SFEM with the use of the new proximity rules suggest that the approximation to deep cracks drastically improves the accuracy of the fatigue crack growth evaluation. Thus, the approximation to deep cracks must be a promising approach for having better evaluation of fatigue crack growth of subsurface cracks.
Wnt5a Signaling Promotes Host Defense againstLeishmania donovaniInfection

Published: June 2017

Leishmania donovani infects macrophages, disrupting immune homeostasis. The underlying mechanism that sustains infection remains unresolved. In view of the potential of Wnt5a signaling to support immune homeostasis, we evaluated the interrelationship of Wnt5a signaling and Leishmania donovani infection. Upon infecting macrophages separately with antimony drug–sensitive and –resistant L. donovani, we noted disruption in the steady-state level of Wnt5a. Moreover, inhibition of Wnt5a signaling by small interfering RNA transfection in vitro or by use of inhibitor of Wnt production in vivo led to an increase in cellular parasite load. In contrast, treatment of macrophages with recombinant Wnt5a caused a decrease in the load of antimony-sensitive and -resistant parasites, thus confirming that Wnt5a signaling antagonizes L. donovani infection. Using inhibitors of the Wnt5a signaling intermediates Rac1 and Rho kinase, we demonstrated that Wnt5a-mediated inhibition of parasite infection in macrophages is Rac1/Rho dependent. Furthermore, phalloidin staining and reactive oxygen species estimation of Wnt5a-treated macrophages suggested that a Wnt5a-Rac/Rho–mediated decrease in parasite load is associated with an increase in F- actin assembly and NADPH oxidase activity. Moreover, live microscopy of L. donovani–infected macrophages treated with Wnt5a demonstrated increased endosomal/lysosomal fusions with parasite-containing vacuoles (parasitophorous vacuoles [PV]). An increase in PV–endosomal/lysosomal fusion accompanied by augmented PV degradation in Wnt5a-treated macrophages was also apparent from transmission electron microscopy of infected cells. Our results suggest that, although L. donovani evades host immune response, at least in part through inhibition of Wnt5a signaling, revamping Wnt5a signaling can inhibit L. donovani infection, irrespective of drug sensitivity or resistance.
Vegetation Map of South Africa, Lesotho and Swaziland 2009 and 2012: A description of changes from 2006
Authors: Dayaram Anisha , Powrie Leslie , Rebelo Tony , Skowno Andrew
Published: June 2017

Background: The variety of applications in which the Vegetation Map of South Africa, Lesotho and Swaziland (VEGMAP) is used requires the map to be continually updated and refined to reflect the latest available information. The VEGMAP has been updated twice, in 2009 and 2012, since its first release in 2006.Objectives: The first objective is to report on the motivations for changes in the 2009 and 2012 versions. The second objective is to describe new vegetation types and subtypes included in these versions.Method: Changes to the VEGMAP are implemented after a peer-review process that is managed by the National Vegetation Map Committee. Accepted changes are then incorporated into the VEGMAP using GIS software.Results: Seventy-one of the 449 vegetation types were affected by updates. Changes included the addition of new vegetation types and subtypes, modifications to the boundaries of types present in the 2006 VEGMAP and changes to the names of vegetation types.Conclusion: The updates have affected a small portion of the map but have reflected a progressive refinement in quality. Regions that are still mapped at a coarse scale, especially those earmarked for land-use development, should be prioritised for improved map accuracy and classification through a more proactive approach towards vegetation mapping, using guidelines that are under development.
Leadership style and leadership effectiveness: Does cultural intelligence moderate the relationship?
Authors: Solomon Anthony , Steyn Renier
Published: June 2017

Orientation: In an age where subordinate cultural heterogeneity has become the norm, cultural intelligence might assist leaders to improve their effectiveness.Research purpose: This research investigated whether leader cultural intelligence moderated the relationship between leadership style (as represented by empowerment and direction) and leadership effectiveness.Motivation for the study: Although the literature on cultural intelligence has been increasing in quantity, there remained a gap in the understanding of the relationship between leader cultural intelligence, the empowering and directive leadership styles and leadership effectiveness.Research design, approach and method: A quantitative methodology with a cross-sectional survey design was followed. Data were obtained from 1140 staff members employed at 19 South African organisations. Factorial, correlational and moderated multiple regression analyses were performed.Main findings: Although leader cultural intelligence and its dimensions do not moderate the relationship between empowering leadership and leadership effectiveness, they do nonetheless negatively moderate the relationship between directive leadership and leadership effectiveness. This moderation was, however, assessed to be of no practical significance.Practical and managerial implications: As leader cultural intelligence did not act as an important influencer of the relationship between leadership style and leadership effectiveness, it appeared that effective leaders may have used their cultural intelligence to actually guide the selection of an effective leadership style in the first place.Contribution and value add: Being one of the first studies to explore the moderating effect of leader cultural intelligence on the relationship between leadership style and leadership effectiveness, this research has made a valuable contribution to building both the cultural intelligence and leadership knowledge bases.

Published: June 2017

Background: One of the greatest challenges in early communication intervention in South Africa is developing and implementing successful identification strategies in primary health care (PHC). A shortage of trained PHC personnel is one of the barriers to providing adequate health services in South Africa. This dearth of services creates the need to substitute clinician-administered developmental screening tools with parent-administered tools.Aim: To determine the accuracy of the Zulu Parents’ Evaluation of Developmental Status (PEDS) in comparison with the outcome of the English PEDS.Setting: The data were collected in a clinical, non-contrived environment at Stanza Bopape Community Health Clinic in Mamelodi, City of Tshwane.Methods: The PEDS is a standardised, parent-completed questionnaire regarding the child’s general development. The English PEDS was translated into Zulu by a Zulu linguist. There were 99 potential participants in the study of whom 83 met the necessary prerequisites.Results: Of the participants whose home language is Zulu, 54% preferred the PEDS in English over the PEDS in Zulu. This indicates a skewed preference towards English, with only slight associations between language preference and age, education and home language.Conclusion: The Zulu PEDS displayed high positive and negative correspondences, representative of an accurate translation of the English PEDS. It is recommended that this study should be repeated in a community where the majority are Zulu home language speakers.
Metal pollution assessment in a Brazilian hydroelectric reservoir: Geophagus brasiliensis as a suitable bioindicator organism
Authors: Doria Halina Binde , Voigt Carmen Lúcia , Campos Sandro Xavier de , Randi Marco Antonio Ferreira
Published: June 2017

Vossoroca is a reservoir in the Brazilian state of Paraná. Although it is located near big cities and can be used as a human water supply, it has remained unstudied. Concentrations of toxic metals and arsenic in sediments, water, liver, gills, and muscle of Geophagus brasiliensis from the reservoir were analyzed using atomic absorption spectrometry. Histological analyses were performed on the gills and the livers using scanning electron microscopy and light microscopy, respectively. The results showed that Vossoroca sediments were moderately polluted by copper, chromium, nickel and arsenic. Cadmium was above legal limits in the water. Histopathological assessment revealed epithelial alterations in the secondary lamella to be the most common abnormality observed in the gills and necrosis, melanomacrophage centers in the livers. In conclusion, although the reservoir is located in an Environmental Protection Area, it is negatively affected by human activity. Further, Geophagus brasiliensis was a suitable bioindicator for metal pollution studies.
Zoneamento da bacia hidrográfica do rio Moju (Pará): usos da água e sua relação com as formas de uso e cobertura do solo
Authors: Ferreira Susane Cristini Gomes , Lima Aline Maria Meiguins de , Corrêa José Augusto Martins
Published: June 2017

A bacia do rio Moju apresenta diferentes padrões de usos da terra decorrentes de um histórico de expansão do setor agrícola e extrativista no estado. Está inserida na área de projetos desenvolvimentistas da região, com ênfase para a cadeia produtiva do dendê. No presente trabalho, realizou-se um zoneamento da bacia do rio Moju evidenciando a interconexão entre os principais usos e cobertura da terra e os usos da água, demonstrando as pressões sobre os recursos naturais que a bacia está sofrendo. O zoneamento é o produto resultante da associação entre o mapeamento de uso e cobertura da terra e as categorias de usuários da água dos municípios componentes da bacia. Os resultados demonstraram que a maior parcela de usos outorgados tem finalidade industrial, sendo a captação subterrânea massivamente superior a superficial, onde o principal outorgado é a agroindústria do dendê. Somente um pequeno número de habitantes são atendidos pela distribuição de água e ocorrem grandes perdas no sistema de distribuição. A sub-bacia Alto Moju sofre alta pressão sobre os seus recursos naturais. Nota-se que a bacia como um todo ainda possui a maior parte de seu território com cobertura florestal, entretanto a pastagem e a vegetação secundária ocupam áreas expressivas. Em geral, percebe-se que o maior desafio está em alinhar o gerenciamento dos recursos hídricos com uma gestão eficiente de uso do solo.

Published: June 2017

Abstract. We determined NOx emissions from Paris in summer 2009 and winter 2009/2010 by applying the closed integral method (CIM) to a large set of car multi-axis differential optical absorption spectroscopy (MAX-DOAS) measurements performed within the framework of the MEGAPOLI project (http://megapoli.dmi.dk/). MAX-DOAS measurements of the tropospheric NO2 vertical column density (VCD) were performed in large circles around Paris. From the combination of the observed NO2 VCDs with wind fields, the NO2 influx into and the outflux from the encircled area was determined. The difference between the influx and outflux represents the total emission. Compared to previous applications of the CIM, the large number of measurements during the MEGAPOLI campaign allowed the investigation of important aspects of the CIM. In particular, the applicability of the CIM under various atmospheric conditions could be tested. Another important advantage of the measurements during MEGAPOLI is that simultaneous atmospheric model simulations with a high spatial resolution (3 × 3 km2) are available for all days. Based on these model data, it was possible to test the consistency of the CIM and to derive information about favourable or non-favourable conditions for the application of the CIM. We found that in most situations the uncertainties and the variability in the wind data dominate the total error budget, which typically ranges between 30 and 50 %. Also, measurement gaps and uncertainties in the partitioning ratio between NO and NO2 are important error sources. Based on a consistency check, we deduced a set of criteria on whether measurement conditions are suitable or not for the application of the CIM. We also developed a method for the calculation of the total error budget of the derived NOx emissions. Typical errors are between ±30 and ±50 % for individual days (with one full circle around Paris). From the application of the CIM to car MAX-DOAS observations we derive daily average NOx emissions for Paris of 4.0  ×  1025 molec s−1 for summer and of 6.9  ×  1025 molec s−1 in winter. These values are a factor of about 1.4 and 2.0 larger than the corresponding emissions derived from the application of the CIM to the model data, using the Toegepast Natuurwetenschappelijk Onderzoek (TNO) MEGAPOLI emission inventory, in summer and winter, respectively. Similar ratios (1.5 and 2.3 for summer and winter, respectively) were found for the comparison with the Monitoring Atmospheric composition and climate III (MACC-III) emission inventory. The highest NOx emissions were found during some cold days in February. Enhanced domestic heating and a reduced conversion efficiency of catalytic converters might contribute to these enhanced NOx emissions.
Retrogressive thaw slumps temper dissolved organic carbon delivery to streams of the Peel Plateau, NWT, Canada
Authors: Bulger Cara A. , Tank Suzanne E. , Kokelj Steven V.
Published: June 2017

Abstract. In Siberia and Alaska, permafrost thaw has been associated with significant increases in the delivery of dissolved organic carbon (DOC) to recipient stream ecosystems. Here, we examine the effect of retrogressive thaw slumps (RTS) on DOC concentration and transport, using data from eight RTS features on the Peel Plateau, NT, Canada. Like extensive regions of northwestern Canada, the Peel Plateau is comprised of thick, ice-rich tills that were deposited at the margins of the continental ice sheet. RTS features are now widespread in this region, with headwall exposures up to 30 m high, and total disturbed areas often exceeding 30 ha. We find that intensive slumping on the Peel Plateau is universally associated with decreasing DOC concentrations downstream of slumps, even though the composition of slump-derived dissolved organic matter (DOM; assessed using specific UV absorbance and slope ratios) is similar to permafrost-derived DOM from other regions. Comparisons of upstream and downstream DOC flux relative to a conservative tracer suggest that the substantial fine-grained sediments released by slumping may sequester DOC on this landscape. Runoff obtained directly from within slump features, above entry into recipient streams, indicates that the deepest RTS features, which thaw the greatest extent of buried, Pleistocene-aged glacial tills, have the lowest runoff DOC concentrations when compared to upstream, un-disturbed locations. In contrast, shallower features, with exposures that are more limited to a relict Holocene active layer, have within-slump DOC concentrations more similar to upstream sites. Finally, fine-scale work at a single RTS feature indicates that temperature and precipitation serve as primary environmental controls on above-slump and below-slump DOC flux, but that the relationship between climatic parameters and DOC flux is complex for these dynamic thermokarst features. These results demonstrate that we should expect striking variation in thermokarst-associated DOC mobilization across Arctic regions, but that within-region variation in thermokarst intensity and other landscape factors are also important for determining biogeochemical response. An understanding of landscape and climate history, permafrost genesis, soil composition, the nature and intensity of thermokarst, and the interaction of these factors, is critical for predicting changes in land-to-water carbon mobilization in a warming circumpolar world.
Ocean acidification of a coastal Antarctic marine microbial
community reveals a critical threshold for CO2 tolerance in
phytoplankton productivity

Published: June 2017

Abstract. High-latitude oceans are anticipated to be some of the first regions affected by ocean acidification. Despite this, the effect of ocean acidification on natural communities of Antarctic marine microbes is still not well understood. In this study we exposed an early spring, coastal marine microbial community in Prydz Bay to CO2 levels ranging from ambient (343 μatm) to 1641 μatm in six 650 l minicosms. Productivity assays were performed to identify whether a CO2 threshold existed that led to a decline in primary productivity, bacterial productivity, and the accumulation of Chlorophyll a (Chl a) and particulate organic matter (POM) in the minicosms. In addition, photophysiological measurements were performed to identify possible mechanisms driving changes in the phytoplankton community. A critical threshold for tolerance to ocean acidification was identified in the phytoplankton community between 953 and 1140 μatm. CO2 levels ≥ 1140 μatm negatively affected photosynthetic performance and Chl a-normalised primary productivity (csPP14C), causing significant reductions in gross primary production (GPP14C), Chl a accumulation, nutrient uptake, and POM production. However, there was no effect of CO2 on C : N ratios. Over time, the phytoplankton community acclimated to high CO2 conditions, showing a down-regulation of carbon concentrating mechanisms (CCMs) and likely adjusting other intracellular processes. Bacterial abundance initially increased in CO2 treatments ≥ 953 μatm (days 3–5), yet gross bacterial production (GBP14C) remained unchanged and cell-specific bacterial productivity (csBP14C) was reduced. Towards the end of experiment, GBP14C and csBP14C markedly increased across all treatments regardless of CO2 availability. This coincided with increased organic matter availability (POC and PON) combined with improved efficiency of carbon uptake. Such changes in phytoplankton community production could have negative effects on the Antarctic food web and the biological pump, resulting in negative feedbacks on anthropogenic CO2 uptake. Increases in bacterial abundance under high CO2 conditions may also increase the efficiency of the microbial loop, resulting in increased organic matter remineralisation and further declines in carbon sequestration.
Regional detection of canopy nitrogen in Mediterranean forests using the spaceborne MERIS Terrestrial Chlorophyll Index

Published: June 2017

Abstract. Canopy nitrogen (N) concentration and content are linked to several vegetation processes and canopy N concentration is a state variable in global vegetation models with coupled carbon (C) and N cycles. While there is ample C data available to constrain the models, widespread N data are lacking. Remote sensing and vegetation indices have been used to detect canopy N concentration and canopy N content at the local scale in grasslands and forests. In this paper we conducted a regional case-study analysis investigating the relationship between the Medium Resolution Imaging Spectrometer (MERIS) Terrestrial Chlorophyll Index (MTCI) time series from ESA ENVISAT at 1 km spatial resolution and both canopy N concentration (%N) and canopy N content (g m−2) from a Mediterranean forests inventory in the region of Catalonia, NE of Spain. The relationships between the datasets were studied after resampling both datasets to lower spatial resolutions (20 km, 15 km, 10 km and 5 km) and at the initial higher spatial resolution of 1 km. The results at the higher spatial resolution yielded significant relationships between MTCI and both canopy N concentration and content, r2 = 0.32 and r2 = 0.17, respectively. We also investigated these relationships per plant functional type. While the relationship between MTCI and canopy N concentration was strongest for deciduous broadleaf and mixed plots (r2 = 0.25 and r2 = 0.47, respectively), the relationship between MTCI and canopy N content was strongest for evergreen needleleaf trees (r2 = 0.20). At the species level, canopy N concentration was strongly related to MTCI for European Beech plots (r2 = 0.71). These results present a new perspective on the application of MTCI time series for canopy N detection, ultimately leading towards the generation of canopy N maps that can be used to constrain global vegetation models.

Modeling the dynamical sinking of biogenic particles in oceanic flow
Authors: Monroy Pedro , Hernández-García Emilio , Rossi Vincent , López Cristóbal
Published: June 2017

Abstract. We study the problem of sinking particles in a realistic oceanic flow, with major energetic structures in the mesoscale, focussing on the range of particle sizes and densities appropriate for marine biogenic particles. Our aim is to evaluate the relevance of theoretical results of finite size particle dynamics in their applications in the oceanographic context. By using a simplified equation of motion of small particles in a mesoscale simulation of the oceanic velocity field, we estimate the influence of physical processes such as the Coriolis force and the inertia of the particles, and we conclude that they represent negligible corrections to the most important terms, which are passive motion with the velocity of the flow, and a constant added vertical velocity due to gravity. Even if within this approximation three-dimensional clustering of particles can not occur, two-dimensional cuts or projections of the evolving three-dimensional density can display inhomogeneities similar to the ones observed in sinking ocean particles.
Complex principal component analysis of mass balance changes on the Qinghai–Tibetan Plateau
Authors: Zhan Jingang , Shi Hongling , Wang Yong , Yao Yixin
Published: June 2017

Abstract. Climatic time series for Qinghai–Tibetan Plateau locations are rare. Although glacier shrinkage is well described, the relationship between mass balance and climatic variation is less clear. We studied the effect of climate changes on mass balance by analyzing the complex principal components of mass changes during 2003–2015 using Gravity Recovery and Climate Experiment satellite data. Mass change in the eastern Himalayas, Karakoram, Pamirs, and northwestern India was most sensitive to variation in the first principal component, which explained 54 % of the change. Correlation analysis showed that the first principal component is related to the Indian monsoon and the correlation coefficient is 0.83. Mass change on the eastern Qinghai plateau, eastern Himalayas–Qiangtang Plateau–Pamirs area and northwestern India was most sensitive to variation of the second major factor, which explained 16 % of the variation. The second major component is associated with El Niño; the correlation coefficient was 0.30 and this exceeded the 95 % confidence interval of 0.17. Mass change on the western and northwestern Qinghai–Tibetan Plateau was most sensitive to the variation of its third major component, responsible for 6 % of mass balance change. The third component may be associated with climate change from the westerlies and La Niña. The third component and El Niño have similar signals of 6.5 year periods and opposite phases. We conclude that El Niño now has the second largest effect on mass balance change of this region, which differs from the traditional view that the westerlies are the second largest factor.
Vigilar y corregir: el trabajo social en las obras de Foucault y Donzelot
Authors: García Martín Lorenzo
Published: June 2017

El texto presenta una aproximación teórica a las miradas postestructuralistas sobre el trabajo social. En concreto, se analiza el lugar que Michel Foucault y Jacques Donzelot conceden al trabajo social en el conjunto de transformaciones de las estrategias de poder de los últimos tres siglos. En el centro de la argumentación tienen especial protagonismo el desarrollo de la biopolítica, la constitución de las familias nucleares en las clases populares, la emergencia de lo social y su reciente devenir en lo social competitivo. Se extrae de la indagación teórica y bibliográfica que, para estos autores, el trabajo social constituye un conjunto de prácticas que cumplen la función social de vigilancia-corrección,  en especial sobre los sujetos agrupados en categorías de grupos vulnerables. Se aporta una perspectiva crítica e histórica de la intervención social profesional, entendida como fuerza normalizadora, que lleva los discursos higienistas, familiaristas y psicológicos hacia las clases populares. El trabajo social se inserta en la regulación de las familias modernas, la crianza de los hijos y la expansión de las políticas sociales, y en este sentido, desempeña un rol crucial en la gestión del conflicto social.
«Precariado» y control social: asistencialismo y exclusión en el ámbito de la salud mental
Authors: Desviat Manuel
Published: June 2017

La actividad comunitaria, sanitaria y social, precisa de un Estado que garantice las prestaciones sociales. En el actual escenario político-económico internacional, donde prima la ganancia de un pocos frente a la solidaridad, el trabajo social y de salud mental se encuentran en la disyuntiva de ser integrados como técnicas asistenciales para paliar los fallos del sistema o la acción a contracorriente conquistando espacios en el horizonte de una sociedad del bienestar. El hecho es que desde el año 2008, inicio de la crisis financiera, se ha incrementado la renta de los más ricos de los ricos y se han acrecentado las desigualdades en el mundo, precarizando las clases medias, especialmente en el sur de Europa. En España hoy resulta difícil hablar de derechos sociales para toda la ciudadanía, pues amplias franjas de la población no tienen garantizado el derecho a la atención sanitaria, a la vivienda o a prestaciones sociales esenciales. Se impone un asistencialismo graciable, una vuelta a criterios propios de la beneficencia, y a la instrumentalización de los recursos públicos como medios de control social.
Invisibles de Tetuán (Madrid). Hacia una práctica subversiva de apoyo mutuo en contextos de exclusión
Authors: Herrera Pineda Ivonne , Pereda Olarte Carlos
Published: June 2017

El proceso creciente de desigualdades sociales en España se manifiesta con crudeza en espacios urbanos como en el distrito madrileño de Tetuán. El desempleo, la precariedad laboral o la debilidad de los sistemas de protección social han generado situaciones de gran vulnerabilidad entre la población. En este contexto los Servicios Sociales operan condicionados por la burocratización, la visión asistencialista y la falta de recursos. Todo ello impide respuestas multidimensionales a la exclusión, imposibilitando un trabajo transformador. Invisibles de Tetuán parte del trabajo colectivo y de la auto-organización vecinal para visibilizar realidades muy diversas de exclusión y buscar su transformación en diversas escalas. Desde el apoyo mutuo, el respeto a la diversidad y la metodología horizontal propia del 15M, este pequeño grupo plantea alternativas al individualismo y ensaya herramientas para la construcción de una sociedad más justa y una política social más eficiente.

From Catholic Social Thought to Catholic Economics and Back: António Almodovar’s interest into an unexpected subject
Authors: Teixeira Pedro
Published: June 2017

En la última década de su carrera antes de su inesperada muerte, la investigación de António Almodovar estuvo dominada por su interés en el pensamiento económico católico, aparentemente una derivación inesperada en su trayectoria. Sin embargo, encajaba en su enfoque más amplio de la historia de economía, que enfatizaba la diseminación de ideas económicas como en su trabajo anterior sobre la institucionalización de economía política o de los debates parlamentarios o manuales. Su interés por la relación entre el pensamiento religioso y económico también responde a una reflexión sobre las fronteras del pensamiento económico y su evolución.
El ecofeminismo crítico de Alicia Puleo: tejiendo el hilo de la «Nueva Ariadna»
Authors: Tapia González Georgina Aimé
Published: June 2017

Resumen La reflexión sobre feminismo y medio ambiente ha cobrado mayor relevancia en las últimas décadas. Sin embargo, el ecofeminismo suscita la descalificación de numerosas pensadoras debido a la popularización de las versiones consideradas “clásicas”, de corte esencialista. En este contexto, la aportación de Alicia Puleo es fundamental porque, a partir de sus análisis de la Modernidad, ha rastreado los orígenes ilustrados del feminismo, la ética ecológica y la extensión de las consideraciones morales más allá del ámbito humano. De no ser por el trabajo que ha realizado esta filósofa, se conocería muy poco sobre ecofeminismo constructivista en lengua castellana. Ahora bien, el objetivo de este artículo es presentar el pensamiento de A. Puleo y visibilizar sus aportaciones al ecofeminismo. Lo anterior a través de cuatro apartados: el primero explora las voces olvidadas de la Modernidad; el segundo plantea una lectura de Simone de Beauvoir desde las coordenadas del ecofeminismo; el tercero presenta la propuesta de lo que A. Puleo denomina ecofeminismo crítico y, finalmente, el cuarto examina los principales retos que enfrenta el ecofeminismo ante el ecologismo, el ecosocialismo y el decrecimiento.Palabras clave: Ecofeminismo, Ilustración, ética ecológica, géneroSummaryThe reflection upon feminism and the environment has gained relevance in the past decades. Nevertheless, ecofeminism has arisen discredit among several thinkers due to the popularization of versions considered “classic” and essentialist. In this context, Alicia Puleo’s contribution is fundamental because, based on her analysis of Modernity, she has traced the illustrated origins of feminism, of environmental ethics, and of the spread of moral considerations beyond the human scope. If we lacked the work that has been carried out by this philosopher, very little would be known of constructivist ecofeminism in Spanish speaking countries. Having said that, the objective of this article will be to present A. Puleo’s thinking and to make visible her contributions to ecofeminism. This will be accomplished through four sections: the first one explores the forgotten voices of Modernity; the second sets out a reading of Simone de Beavoir from the perspective of critical ecofeminism; the third presents the proposal that A. Puleo has named critical ecofeminism, and finally the fourth examines the main challenges ecofeminism faces regarding environmentalism, ecosocialism and the downturn.Key terms: Ecofeminism, Illustration, Environmental Ethics, Gender

Published: June 2017

The aim of this work was measurement of the curd firmness prepared by different volume of rennet solution and comparison of differences of curd firmness between these volumes. Further, it was observed the influence of different volumes of rennet up to thevolume of whey release, curd firmness, dry matter of curd and dry matter of whey. The composition of milk was determined according ISO and Czech state standard. Dry matter content (%) was determined by gravimetry, in drying oven at 102 °C to constant weight (ISO 6731:2010), the protein content (%) by Kjeldahl´s method (EN ISO 8968-1:2002), content of fat (%) by Gerber´s acidobutyrometric method (ISO 2446:2008), content of lactose by polarimetry, titratable acidity by titration Soxhlet-Henkel method, pH and calcium content in milk (g.L-1) was determined by complexometric titration with flueroxone as an indicator according to Czech state standart No 57 0530. For coagulation was used microbial rennet CHY-MAXRM 200. There were measured: curd firmness, rennet coagulation time, curd quality, volume of released whey, weight of curd, dry matter of curd and dry matter of whey. Different volumes of rennet solution had influence on curd firmness. Curd firmness (volume of rennet solution) had no significant influence on curd quality (five grade scale). Curd firmness had influence on volume of whey release (mL) out of the curd. With the increasing curd firmness s increased the volume of whey released from the curd. The volume of rennet solution had an influence on weight of curd. Curd dry matter raised with higher volume of rennet solution. Volume of added rennet solution had no statistically significant effect on the change of whey dry matter.

The comparative study of Sus scrofa muscle tissue with different defects of quality was carried out. Such analysis methods as determination of water-binding capacity (WBC) and pH values, microstructural studies, proteome methods, mass spectrometric methods, high performance liquid chromatography (HPLC) and determine the concentration of cathepsin D, calpain 3 and myoglobin were applied in current study. DFD meat was characterized by high pH (6.2) and WBC (93.18%), while PSE - low pH (5.5) and WBC (79.19%). pH and WBC values in NOR pork was medium and averaged 5.9 and 92.05%, respectively. Microstructural studies revealed that fiber in exudative pork was the least and averaged 39.7 µm, normal pork was characterized by diameter of muscle of 45.5 µm, while DFD pork ‑ 48.3 µm. Protein composition of Sus scrofa muscle tissues were also investigated by one-dimensional and two-dimensional electrophoresis. 6 protein fractions were identified by mass spectrometry and confirmed as potential biomarkers of pork quality defects in meat and processes meat product. It also has been shown that PSE pork contains 8 characteristic peptides, NOR - 14, DFD - 18. Cathepsin D, calpain 3 and myoglobin content were measured in pork of different categories. The highest content of cathepsin D, calpain 3 and myoglobin was noticed in PSE pork and averaged 82.16 ±3.30 ng.mL-1; 1.280 ±0.082 ng.mL-1; 3.973 ±0.506 ng.mL-1, respectively. Since the study was carried out on samples of meat 24 hours after slaughter, this work had the prospect to further study of meat with different defects of quality during long-term autolysis.

Maillard reaction has been well understood as a non-enzymatic reaction between reducing sugars and amino acids to generate the Maillard reaction products (MRPs). This study is aimed to demonstrate the browning intensity, color development, spectra measurements, scavenging activity, and the correlation between browning intensity and scavenging activity of the MRPs generated from D-Psicose and Methionine (Psi-Met) at 50â„ƒ. The browning intensity of MRPs was investigated based on the absorbance using spectrophotometer at 420 nm, the color development was observed using digital colorimeter to gained L*a*b* value then calculated as browning index, the spectra development was analyzed using spectrophotometer at 190 - 750 nm, and the scavenging activity was determined with ABTS method using spectrophotometer at 734 nm. The browning intensity, color development, and scavenging activity were improved along with the increase in heating process. Based on spectra analysis, MRPs from Psi-Met was initially detected at 21 h and Psi at 24 h of heating treatment, which indicating that Psi-Met have faster and better reaction than Psi during heating process. Positive non-linear and significant correlation between browning intensity and scavenging activity were assigned. This finding may provide beneficial information of D-psicose and MRPs to the next scientific research and to the food industries which applies MRPs in their products.

O espaço redundante: O papel da paisagem na narrativa cinematográfica de ‘As Vinhas da Ira’ (1940)
Authors: Oliveira Celso Fernando Claro de
Published: June 2017

O presente artigo apresenta discussões sobre a representação das paisagens estadunidenses no filme “As vinhas da ira” (John Ford, 1940). Valendo-me das premissas da História Social do Cinema, pretendo analisar como essas representações veiculam determinados valores e ideias a partir dos elementos que compõem a mise-en-scène fílmica e como estes mudam de acordo com o teor de cada sequência a fim de corroborar determinados apelos emocionais. Para tanto, serão levadas em consideração o papel do espaço diegético na narrativa clássica hollywoodiana, bem como, o contexto de produção do filme.
