Desenvolvimento de um protocolo de avaliação do desempenho de recursos humanos em instituições de ensino superior/IES: notas para a gestão acadêmica a partir do caso do Curso de Turismo/UFJF – Brasil
Authors: Pimentel Thiago Duarte , Paula Sara Conceição
Published: June 2014

Este artigo apresenta parte dos resultados de uma pesquisa realizada sobre a formação e inserção profissional no mercado de trabalho na área do turismo, no Brasil. Especificamente, discute-se aqui a realização de uma avaliação da gestão acadêmica do curso superior de bacharelado em turismo numa universidade federal brasileira à luz da gestão de seus recursos humanos. O estudo desenvolve uma metodologia própria, um protocolo de análise do perfil docente, baseado no cruzamento de técnicas de pesquisa quantitativas e qualitativas, suportado pela existência de um sistema nacional de base de dados e informações de docentes e pesquisadores que alimenta e torna possível a aplicação do protocolo. Os resultados encontrados evidenciam, em geral, a produtividade coletiva e o seu perfil relacionado ao caso em estudo e, em particular, os graus de especialização e assimetria na produtividade individual dos docentes, além de eventuais incongruências entre a especialização dos profissionais versus as áreas de atuação, disciplinas lecionadas e orientações realizadas. Como conclusão, duas contribuições centrais são advogadas: (1) a elaboração de um protocolo pesquisa próprio, e (2) os indicadores dele derivados que servem tanto para o levantamento de diagnóstico, para o monitoramento e avaliação do desempenho da gestão acadêmica.

Authors: Lavall Jaqueline , Barden Júlia Elisabete
Published: June 2014

O presente trabalho tem como objetivo verificar as contribuições do estágio não obrigatório para a formação acadêmica e profissional dos estudantes da Univates. Para atingir esse objetivo, buscou-se compreender o perfil dos estagiários, cursos e empresas concedentes, a relação estabelecida entre a teoria com a prática e com o mercado de trabalho, além de verificar a necessidade de adotar novas práticas pela Univates em relação aos estágios não obrigatórios de seus estudantes. A revisão da literatura trata de temas como a evolução do estágio no Brasil, aspectos da Lei nº 11.788/08, que regulamenta o estágio não obrigatório, e conceitos de estágio. No que se refere à metodologia, trata-se de um estudo exploratório, realizado por meio de pesquisa bibliográfica e levantamento. Os resultados apontam que o estágio não obrigatório contribui de forma positiva para a formação acadêmica e profissional dos estudantes. Em contrapartida, foi revelado certo descontentamento com a supervisão realizada pela Univates, o que pode ser visto como uma oportunidade de melhoria para a Instituição.

Sources contributing to background surface ozone in the US Intermountain West

Published: June 2014

Abstract. We quantify the sources contributing to background surface ozone concentrations in the US Intermountain West by using the GEOS-Chem chemical transport model with 1 / 2° × 2 / 3° horizontal resolution to interpret the Clean Air Status and Trends Network (CASTNet) ozone monitoring data for 2006–2008. We isolate contributions from lightning, wildfires, the stratosphere, and California pollution. Lightning emissions are constrained by observations and wildfire emissions are estimated from daily fire reports. We find that lightning increases mean surface ozone in summer by 10 ppbv in the Intermountain West, with moderate variability. Wildfire plumes generate high-ozone events in excess of 80 ppbv in GEOS-Chem, but CASTNet ozone observations in the Intermountain West show no enhancements during these events nor do they show evidence of regional fire influence. Models may overestimate ozone production in fresh fire plumes because of inadequate chemistry and grid-scale resolution. The highest ozone concentrations observed in the Intermountain West (> 75 ppbv) in spring are associated with stratospheric intrusions. The model captures the timing of these intrusions but not their magnitude, reflecting numerical diffusion intrinsic to Eulerian models. This can be corrected statistically through a relationship between model bias and the model-diagnosed magnitude of stratospheric influence; with this correction, models may still be useful to forecast and interpret high-ozone events from stratospheric intrusions. We show that discrepancy between models in diagnosing stratospheric influence is due in part to differences in definition, i.e., whether stratospheric ozone is diagnosed as produced in the stratosphere (GEOS-Chem definition) or as transported from above the tropopause. The latter definition can double the diagnosed stratospheric influence in surface air by labeling as "stratospheric" any ozone produced in the troposphere and temporarily transported to the stratosphere. California pollution influence in the Intermountain West frequently exceeds 10 ppbv but is generally not correlated with the highest ozone events.
A model study on changes of European and Swiss particulate matter, ozone and nitrogen deposition between 1990 and 2020 due to the revised Gothenburg protocol

Published: June 2014

Abstract. We report a study of changes in air quality due to emission reductions using the chemical transport model CAMx. The model domain includes all of Europe with a nested domain over Switzerland. The model simulations were performed for 1990 (the reference year for the Gothenburg Protocol), 2005 (the reference year for the revised Gothenburg Protocol), 2006 (for model validation) and 2020 (the target year for the revised Gothenburg Protocol) using three emission scenarios prepared by IIASA/GAINS. Changes in ozone, particulate matter and nitrogen deposition are the central theme of the study. The relative changes in the annual average PM2.5 concentrations between 1990 and 2005 were reproduced very well. Both model results and observations show that annual mean concentrations of PM2.5 decreased by about 20–50% in Europe. Simulations using the baseline scenario (BL 2020) suggest that PM2.5 concentrations in 2020 will be about 30% lower than those in 2005. The largest predicted decrease in PM2.5, based on the MTFR (Maximum Technically Feasible Reduction) scenario, was about 60% and was located mainly in the eastern part of Europe. In the case of ozone, both model results and measurements show an increase in the mean ozone mixing ratios between 1990 and 2005. The observations, however, suggest a larger increase, indicating the importance of background ozone levels. Although emission reductions caused a decrease in peak ozone values, ozone levels in polluted regions increased due to reduced titration with nitric oxide (NO). This caused a change in the frequency distribution of ozone. Model simulations using emission scenarios for 2020 suggest that annual average ozone mixing ratios will continue to increase. Changes in the levels of the damage indicators AOT40 for forests and SOMO35 are reported as well. The model results suggest that nitrogen deposition decreased by 10–30% in the eastern part of Europe since 1990, while it increased by about 20% in the Iberian Peninsula. The decrease is mainly due to the deposition of oxidized nitrogen species, whereas deposition of reduced nitrogen compounds increased. In Switzerland, nitrogen deposition is larger in the northern part of the Alps where ammonia emissions are the highest. Applying the baseline scenario, we found that the deposition of oxidized nitrogen compounds will have decreased by a further 40% by 2020, whereas deposition of reduced species will continue to increase. This will lead to a 10–20% decrease in the total nitrogen deposition in most of the model domain, with a 10% increase in the eastern part of Europe.
Model study of the impacts of future climate change on the hydrology of Ganges–Brahmaputra–Meghna (GBM) basin

Published: June 2014

Abstract. The intensity, duration, and geographic extent of floods in Bangladesh mostly depend on the combined influences of three river systems, Ganges, Brahmaputra and Meghna (GBM). In addition, climate change is likely to have significant effects on the hydrology and water resources of the GBM basins and might ultimately lead to more serious floods in Bangladesh. However, the assessment of climate change impacts on basin-scale hydrology by using well-constrained hydrologic modelling has rarely been conducted for GBM basins due to the lack of data for model calibration and validation. In this study, a macro-scale hydrologic model H08 has been applied regionally over the basin at a relatively fine grid resolution (10 km) by integrating the fine-resolution (~0.5 km) DEM data for accurate river networks delineation. The model has been calibrated via analyzing model parameter sensitivity and validated based on a long-term observed daily streamflow data. The impact of climate change on not only the runoff, but also the basin-scale hydrology including evapotranspiration, soil moisture and net radiation have been assessed in this study through three time-slice experiments; present-day (1979–2003), near-future (2015–2039) and far-future (2075–2099) periods. Results shows that, by the end of 21st century (a) the entire GBM basin is projected to be warmed by ~3°C (b) the changes of mean precipitation are projected to be +14.0, +10.4, and +15.2%, and the changes of mean runoff to be +14, +15, and +18% in the Brahmaputra, Ganges and Meghna basin respectively (c) evapotranspiration is predicted to increase significantly for the entire GBM basins (Brahmaputra: +14.4%, Ganges: +9.4%, Meghna: +8.8%) due to increased net radiation (Brahmaputra: +6%, Ganges: +5.9%, Meghna: +3.3%) as well as warmer air temperature. Changes of hydrologic variables will be larger in dry season (November–April) than that in wet season (May–October). Amongst three basins, Meghna shows the largest hydrological response which indicates higher possibility of flood occurrence in this basin. The uncertainty due to the specification of key model parameters in predicting hydrologic quantities, has also been analysed explicitly in this study and found that the uncertainty in estimation of runoff, evapotranspiration and net radiation is relatively less. However, the uncertainty in estimation of soil moisture is quite large (coefficient of variation ranges from 11 to 33% for three basins). It is significant in land use management, agriculture in particular and highlights the necessity of physical observation of soil moisture.
In Vitro Antibacterial Activity of Two Mosses: Calymperes erosum C. Mull and Bryum coronatum Schwaegr from South-Western Nigeria

Published: June 2014

Bryophytes are poikilohydric in nature and the oldest known land plant. Their striking resistance to microbial attack suggests their inherent production of antibacterial compounds. The antibacterial activity of acetone, ethanol, methanol and hexane extracts of Calymperes erosum C. Mull and Bryum coronatum Schwaegr were investigated against twenty clinically important bacteria pathogens. Agar dilution method was used to assess the effectiveness of the extracts on the test organisms. The minimum inhibitory concentrations of the extracts of C. erosum were between ˂0.625 and ˃5.0 mg/ml. Klebsiella pneumoniae ATCC 10031, Enterococcus feacalis ATCC 29212, Bacillus pumilis ATCC 14884 and Enterobacter cloaca ATCC 13047 in decreasing order are most sensitive to the extracts while Proteus vulgaris KZN, Staphylococcus aureus OK2 and Shigella sonnei ATCC 29930 were resistant to the extracts. Ethanolic extract was the most effective among the extracts followed by acetone extract. B. coronatum had relatively lower activity. While the mosses screened proved to be promising sources of antimicrobial and biologically active compounds, their toxicity and action mechanism still needed to be investigated.
Genres as Species and Spaces:
Authors: Wells Susan
Published: June 2014

Contemporary genre theory is dominated by metaphors of evolution and speciation; this article proposes alternate metaphors of spatiality and exchange. A spatial understanding of genre permits more productive interactions between literary and rhetorical genre theory. A reading of Robert Burton's The Anatomy of Melancholy as a multigenred text suggests some of the potentials of this approach.
Heidegger and the Aesthetics of Rhetoric
Authors: Reeves Joshua , Stoneman Ethan
Published: June 2014

This article uses Heidegger's critique of the aesthetic tradition to reconsider the limits and potential of aesthetic rhetoric. Contextualizing rhetoric's so-called aesthetic turn within the German aesthetic tradition, we argue that aesthetic rhetoric remains constrained by aesthetics' traditional opposition to the rational and the true. This theoretical heritage has often prevented contemporary aesthetic rhetorical theory from considering the value of art beyond sense experience and ritualized cultural reproduction. We claim, however, that rhetoric can be artistic and at the same time project a community's evolving sense of political and social truth. Through an analysis of Simón Bolívar's Angostura Address, which in 1819 inaugurated a political rebirth of the Venezuelan republic, we demonstrate how the art of rhetoric can exhibit Heidegger's three senses of “aletheiaic” truth: the bestowing, grounding, and beginning of a political community.
Factors related to the adoption of organic farming in Spanish olive orchards
Authors: Parra López C. , Calatrava Requena J.
Published: June 2014

The area given over to the cultivation of organic olive trees in Spain has greatly increased in the last ten years. The diffusion of organic farming is desirable since its principles are in line with the aim of the current EU Common Agricultural Policy to harmonise agrarian production and environmental protection, and to encourage the production of quality agricultural goods. This paper characterises organic olive growers and farms in the south of Spain and compares them to their conventional counterparts. Information was gathered in a survey of 322 olive growers. The organic growers differed from their conventional counterparts in that their orchards were less productive and in the more part-time nature of their dedication to agriculture. They were also younger, more involved in management and administration of the holding, attended more courses, were more commonly members of agricultural associations, received more information via the Andalusian Committee for Organic Agriculture (a control, certification and training organization), had a more negative opinion regarding the use of chemicals, and believed that organic agriculture required more time and effort but provided greater returns.
Seasonal variations of rosmarinic and carnosic acids in rosemary extracts. Analysis of their in vitro antiradical activity
Authors: Luis J.C. , Johnson C.B.
Published: June 2014

Rosemary plants were analysed using HPLC and eight different compounds (vanillic acid, caffeic acid, rosmarinic acid, naringin, hispidulin, cirsimaritin, carnosol and carnosic acid) were identified and quantified. The analysis of the DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity revealed that rosmarinic and carnosic acids were the best rosemary scavengers with IC sun(50) values of 27 and 32 micro M, respectively. Environmental influences on rosmarinic and carnosic acids content in rosemary plants were studied over a period of one year under southern UK conditions. Carnosic acid reached the maximum concentrations in December, decreasing by 50% during the summer months, while rosmarinic acid showed a constant concentration during the year. The significance of these results has been discussed later in this paper.
Effect of row spacing and lineal sowing density of kenaf (Hibiscus cannabinus L.) yield components in the North-West of Argentina
Authors: Acreche M. , Gray L.N. , Collavino N.G. , Mariotti J.A.
Published: June 2014

The plant density and spatial arrangement of kenaf is an important aspect in kenaf fiber production. A field plant density experiment was conducted at Ledesma (Jujuy, Argentina) in 2001 on a sandy loam soil. The treatments used were different combinations of 35 and 70 cm row spacings with lineal sowing densities of 25 and 40 plants m-1, and were applied to the Cuba 108, Endora and Tainung 1 cultivars. Two indices (bark content and bark index) related to fiber yield and useful for the individual selection of plants were measured. The combination of 35 cm row spacing and 25 plants m-1 lineal sowing density, representing an initial density of 714,286 plants ha-1, resulted in the best dry bark yield for the three cultivars. As a result of strong intraspecific competition, height and diameter of the plants decreased while plant density increased. The initial lineal density of 40 plants m-1 was not advantageous in comparison to 25 plants m-1, because plant survival rates were reduced at 40 plants m-1 and yield did not increase linearly.
Influence of earthworms on organic waste composting and characterisation of vermicompost end products
Authors: Castillo E. , Benito S.G. , Iglesias M.C.
Published: June 2014

The aim of this work was to study the influence of earthworms on the composting process. Selected waste mixtures pine sawdust + poultry litter (M1), cotton industry waste + poultry litter (M2), shredded paper + horse manure (M3), and cotton industry waste + horse manure (M4) were composted for 85, 64, 60 and 60 days respectively in plastic boxes. The temperature variations during this process followed the typical three-phase pattern. At the end of this process 95, 80, 75 and 95 g of Eisenia andrei were added to each treatment respectively to initiate vermicomposting. Together, the composting and vermicomposting processes took between 105 and 175 days. Earthworm biomass decreased in M1 and M2, and increased in M3 and M4. The physical, chemical and biological variables measured, such as time to compost maturity, the changes in earthworm population, the C/N ratio, and the availability of nutrients, showed that M3 was the best medium for earthworm activity, and that M4 had the best chemical and physical properties as an organic manure. Mixtures containing poultry litter were not suitable for vermicomposting. However, M1 was the best mixture in a test involving the growth of ryegrass (Lolium perenne cv. Weterwald); compared to controls, a 120% dry weight yield was obtained.
Innovations favouring environmental sustainability in avocado orchards: an analysis of the Spanish Mediterranean coastlands
Authors: Sayadi S. , Calatrava Requena J. , Guirado Sánchez E.
Published: June 2014

Avocado cultivation started to take hold on the Southern Spanish Mediterranean coast in the early 1970s. Today, avocado is the most widespread tropical crop in the area, occupying some 8,350 ha; average annual production is around 70,000 Mg. In recent years, several technological innovations have been adopted by avocado growers, some of which favour the environmental sustainability of the crop. Among the practices adopted are several non-tillage or conservation tillage techniques (which use no or very little herbicide), flower pruning, the use of weed clearing machines, mulching, and organic and integrated farming systems. This paper reports the results of a survey of avocado growers from the southeastern coast of Spain, and analyses their adoption of environmentally friendly technologies. To identify the grower and orchard characteristics that encourage such adoption, an aggregate innovation index was created and a multinomial ordered probit model constructed. The findings might help in the design of strategies for increasing the adoption of environmentally safe technologies.
Comparison of the pesticide coverage achieved in a trellised vineyard by a prototype tunnel sprayer, a hydraulic sprayer, an air-assisted sprayer and a pneumatic sprayer

Published: June 2014

Spraying is the main method used to apply pesticides to trellised vines in Castilla-La Mancha, Spain. If the efficiency of spray applications is to be improved, the amount of pesticide employed is to be reduced, and the performance of existing and new spray technology enhanced, the leaf coverage achieved must be known and a system developed that can rapidly determine it. With these aims in mind, the authors built and tested a prototype tunnel sprayer and compared its efficiency to the three types of sprayer most commonly used in the region: the hydraulic sprayer, the air-assisted sprayer and the pneumatic sprayer. To determine and compare the coverage produced by these four machines, a rapid analysis system that combines the use of water-sensitive paper strips and an artificial vision system was developed. All four machines were used to spray a commercial fungicide (dose 200 L haE-1) at working pressures of 0.1, 0.3 and 0.6 MPa onto vines in a trellised vineyard. With all four models, the quality of the application improved with the spraying pressure, although the best spraying coverage was obtained with tunnel sprayer. Even though the results obtained were not optimum (the formation of a uniform film of fungicide on the leaf surface), the mean coverage achieved by the tunnel sprayer (as recorded by the water-sensitive papers attached to the leaves) was 54%, and on occasion over 79%.

Shade nets effect on canopy light distribution and quality of fruit and spur leaf on apple cv. Fuji
Authors: Dussi M.C. , Giardina G. , Sosa D. , González Junyent R. , Zecca A. , Reeb P. Reeb
Published: June 2014

The upper region of the Río Negro and Neuquén valley, Argentina (latitude: 38 degrees 55 minutes South) experiences high temperatures and light intensities before the apple harvest. This hinders these fruits turning red and increases the risks of them becoming sunburnt. In the December of two growing seasons (when the fruits were about 43 mm in diameter), still some 80 days before harvest, 15% and 55% density shade nets were placed over "Fuji" apple trees. At harvest time, light distribution was determined at two canopy heights (1 and 3 m) on either side of the trees. Fruiting spurs were examined, and colour, sunburn damage, weight, soluble solid content and flesh firmness of the fruits determined. Specific leaf weight (SLW) was also established. Shade nets notably decreased the amount of photosynthetically active radiation (PAR) available; they also reduced fruit colour (redness), soluble solid content and flesh firmness, and the SLW. The 55% density net decreased fruit sunburn, but no differences were found between the 15% density net and control treatments. Spurs at the bottom of the canopy received less light, and the SLW, as well as the colour and soluble solid content of their fruit, was lower than observed for the higher spurs. The impossibility of exporting fruits damaged by high temperatures and intense solar radiation during ripening requires shade nets be used, their density depending on the conditions experienced.
Short communication. Nitrate reductase activity in roots and leaves of chickpea cultivars under salt stress
Authors: Garg N. , Singla R.
Published: June 2014

Four chickpea cultivars (CSG 9651, BG 267, CSG 8962 and DCP 92-3) were grown to maturity under salinity conditions of 0, 4, 6 and 8 dS mE-1. Nitrate reductase activity decreased progressively with increasing salinity, although variation was seen between the cultivars. Cultivar CSG 9651, a kabuli or Mediterranean type, appeared to be the best adapted to saline stress, maintaining growth and showing efficient nitrate reduction under these conditions.

L’assentament territorial de la població immigrada ha esdevingut una realitat tangible. La crisi econòmica ha aguditzat, a més, l’interès respecte als nivells de concentració d’aquesta població. En aquest sentit, la formació d’enclavaments ètnics, entesos com a espais residencials amb una representació significativa d’una població estrangera o més, s’ha convertit en un tema d’atenció particular dins les esferes acadèmica i política, però, a hores d’ara, són pocs els treballs que n’han abordat la formació i l’evolució de manera quantitativa. Mitjançant la implementació d’un mètode de classificació residencial que ens permet prendre la secció censal com a unitat d’anàlisi, ens proposem inventariar els diferents tipus d’espais explicitant les característiques demogràfiques bàsiques de les persones que hi resideixen. En particular, les dels habitants de les quaranta-vuit seccions censals que, l’any 2011, podien ser considerades enclavaments, tot avaluant quina ha estat la tendència, en termes de graus d’exclusivitat residencial, per al conjunt d’àrees d’assentament abans i durant la crisi econòmica.

Se contextualizará la denominada “feminización” de las migraciones, revisaremos algunos discursos sobre la violencia de género ejercida contra mujeres inmigradas y reflexionaremos en torno a cómo estas construcciones discursivas pueden funcionar como un mecanismo invisibilizador de la agencia y prácticas de resistencia del colectivo de mujeres inmigradas.
La historia de la psicología en clave crítica. Juicios y prejuicios en el análisis de la psicología de la “mujer universitaria” en Argentina a comienzos del siglo XX
Authors: Ostrovsky Ana Elisa
Published: June 2014

La historiografía de la psicología a nivel internacional ha incorporado en las últimas décadas diversas perspectivas críticas que han cuestionado el uso de la categoría “mujer” como dato universal, esencialista y ahistórico. Simultáneamente se ha advertido el papel de la disciplina en la conformación de histórica de los géneros y se ha enfatizado el carácter normativo y normalizador que la misma ha ejercido históricamente como portadora de un discurso sobre las diferencias legitimado científicamente. En el presente trabajo se realizará una reseña de dichos aportes y se ejemplificará dicha perspectiva crítica en un caso particular. Puntualmente se mostrará la relación entre valores de diverso linaje en los desarrollos teóricos sobre la “psicología de la mujer universitaria” a comienzos del siglo pasado en Argentina.
Economía Solidaria e interdependencia: aportes desde perspectivas feministas
Authors: Osorio Cabrera Maria Daniela
Published: June 2014

Con Economía Solidaria (ES) se ha denominado a un conjunto de emprendimientos socio-económicos colectivos que han surgido en la últimas décadas a nivel mundial, caracterizados por el establecimiento de relaciones horizontales entre sus miembros, el carácter eco-sostenible de sus emprendimientos y la conformación de redes colaborativas a nivel local y mundial. Investigadoras feministas plantean que existen ciertos sesgos androcéntricos en la forma de abordar el estudio de la ES. La propuesta en este artículo es ampliar los marcos interpretativos que han analizado estas experiencias. Para ello, parto de realizar un recorrido por las producciones académicas que han abordado la ES desde estudios de género y trabajos feministas, analizando sus aportes y limitaciones. Finalmente introduzco las nociones de interdependencia y sostenibilidad de la vida, herramientas teóricas brindadas desde el feminismo, como un aporte al estudio de estos colectivos.
Tensiones y distensiones en torno a las relaciones de poder en investigaciones feministas con Producciones Narrativas
Authors: Gandarias Goikoetxea Itziar
Published: June 2014

En el presente artículo examino, a partir de un enfoque reflexivo, las dificultades metodológicas que se presentan en investigaciones feministas que apuestan por la construcción de conocimiento colectivo. En base a una investigación en curso expongo algunas de las tensiones surgidas en el campo de investigación en torno a las relaciones de poder entre investigadora y participantes. Partiendo de una perspectiva feminista e interseccional exploro tres propuestas a través de las cuales la técnica de las Producciones Narrativas contrarresta las relaciones de poder: a) la agencia y negociación de las participantes en la construcción de las narrativas; b) la consideración de las Producciones Narrativas como puntos teóricos de partida c) el diálogo y la transformación recíproca entre investigadora y participantes. Finalmente propongo la reflexividad de la incomodidad como una práctica fundamental para habitar ética y políticamente las tensiones e incertidumbres que se presentan en los procesos de investigación.
Metáforas y articulaciones para una pedagogía crítica sobre la interseccionalidad
Authors: Platero Méndez Raquel (Lucas)
Published: June 2014

¿Cómo pensamos sobre las desigualdades múltiples y la interseccionalidad? ¿qué imágenes o metáforas pueden ayudar a entender la organización y las relaciones entre diferentes desigualdades? Usando una mirada histórica, exploraré los conceptos de la simultaneidad, la encrucijada, la discriminación múltiple, las categorías en relación, el agenciamiento y los ensamblajes. Me propongo mostrar mi práctica política y pedagógica sobre la interseccionalidad, mostrando algunas de las preguntas frecuentes que surgen. Es relevante señalar que no se trata tanto de dar cuenta de la diversidad de la ciudadanía, como de evidenciar que existen vivencias que pueden ser señaladas como “abyectas”, o “pertenecientes a los márgenes”, o “disidentes”. Al mismo tiempo, supone la existencia de unos privilegios, así como también son relevantes las posibilidades de agencia y empoderamiento de los sujetos.

Diskursivní rovina sporu o volební reformu v Rumunsku v roce 2012
Authors: Jarabinský Ivan
Published: June 2014

This article deals with the argumentation between opponents and advocates of the electoral reform which was approved by the Romanian parliament in May 2012. The text discusses the validity of the arguments raised by both sides of the dispute. For this purpose, the text considers only parliamentary debates and the argumentation of the Constitutional Court. The author employs arguments from the fields of political science and law to discuss the three main areas of the dispute. These are the representativeness of the intended electoral system, the number of elected representatives, and the timing of the electoral reform. The analysis concludes that the arguments to support each of the two main forms of electoral system – majoritarian and proportional – were used correctly. However, the arguments in favour of each system sometimes omitted important disadvantages connected with that system. Although the Constitution of Romania allows wide-ranging changes to the electoral system, the omitted consequences have to be taken into consideration. The text supplements discussions on electoral engineering with a focus on the constitutionality and validity of the arguments raised during the debate. From this perspective, it is necessary to take into consideration not just the mechanical effects of the electoral system but also its possible broader impact.
Strana svobodných občanů – čeští monotematičtí euroskeptici?

When, in the beginning of 2009, the Party of Free Citizens was founded, it was believed that the main impulse for establishing a new political party was the generally positive approach towards the Lisbon Treaty adopted by the Civic Democratic Party (ODS) a couple of months before. Thus, since its foundation, the media, commentators and political analysts have labelled the Party of Free Citizens as a single issue Eurosceptic party. This article challenges this prevailing evaluation of the Party of Free Citizens and subsequently confronts the party´s programs and press releases with three concepts – the concept of Euroscepticism connected with the work of Taggart and Szczerbiak, the concept of a single issue party developed by Mudde, and the concept of a niche party brought into political science by Meguide. The article concludes that while the Party of Free Citizens is undoubtedly a Eurosceptic party, both in terms of its soft and hard versions, its overall performance as a political entity does not meet the criteria of Mudde´s concept of a single issue party. As the Party of Free Citizens puts a strong emphasis on European issues (compared to other mainstream Czech political parties), it can, at most, be described as a niche party.
Analýza vývoje vnímání národní identity německou CDU v letech 1990–2009
Authors: Vít Michal
Published: June 2014

The paper aims to explain the development of the perception of national identity of the Christian Democratic Party (CDU), the strongest German political party in the past few decades. The paper focuses on election manifestos for the 1990, 1994, 1998, 2002, 2005, and 2009 elections. For this purpose, each manifesto is examined according to up to five analytical categories – such as values, nation, Europe, threats, and society. These categories explore the party’s perception in a wider context instead of focusing only on direct  references to national identity. The analysed period was divided into three phases with an emphasis on the internal crisis between the years 1998 and 2002. The crisis influenced policy priorities; therefore the perceptions of elements belonging to national identity were changed in order i) to gain victory in the general elections in 2002 and 2005, and ii) to reflect properly the state of German society. Therefore, significant policy shifts were made. These policy changes show how the party successfully integrated societal demands and preferences over the past decade. Thank to this, the CDU incorporated both conservative and liberal elements. This is evident in the case of incorporating liberal elements such as homosexual partnerships while, at the same time, actively stressing the importance of defending national interests.
L’expérience des parents d’un enfant d’orientation homosexuelle : savoirs issus des recherches et perspectives d’intervention
Authors: Lavoie Kévin , Côté Isabel
Published: June 2014

Au cours des trente dernières années, plusieurs chercheurs et intervenants sociaux se sont intéressés à l’expérience des jeunes de minorités sexuelles, particulièrement en ce qui concerne le dévoilement de leur orientation sexuelle et ses répercussions sur le plan de la santé physique et mentale. Or, peu d’études ont exploré le point de vue des parents d’un enfant d’orientation homosexuelle. L’objectif principal de cet article est de faire l’état des connaissances à propos de l’expérience singulière de ces parents, au regard de la diversité de leurs réactions à l’annonce de l’homosexualité de leur enfant et l’émergence de leur nouvelle identité parentale et conjugale. Cette démarche s’inscrit dans une volonté d’acquérir une compréhension et une analyse critique de ce phénomène, en plus de documenter les pratiques d’intervention psychosociale et communautaire développées à l’intention des parents.

Correcting artifacts in transition to a wound optic fiber: Example from high‐resolution temperature profiling in the Dead Sea
Authors: Arnon Ali , Selker John , Lensky Nadav
Published: June 2014

Spatial resolution fiber‐optic cables allow for detailed observation of thermally complex heterogeneous hydrologic systems. A commercially produced high spatial resolution helically wound optic fiber sensing cable is employed in the Dead Sea, in order to study the dynamics of thermal stratification of the hypersaline lake. Structured spatial artifacts were found in the data from the first 10 m of cable (110 m of fiber length) following the transition from straight fiber optic. The Stokes and Anti‐Stokes signals indicate that this is the result of differential attenuation, thought to be due to cladding losses. Though the overall spatial form of the loss was consistent, the fine structure of the loss changed significantly in time, and was strongly asymmetrical, and thus was not amenable to standard calibration methods. Employing the fact that the cable was built with a duplex construction, and using high‐precision sensors mounted along the cable, it was possible to correct the artifact in space and time, while retaining the high‐quality of data obtained in the early part of the cable (prior to significant optical attenuation). The defect could easily be overlooked; however, reanalyzing earlier experiments, we have observed the same issue with installations employing similar cables in Oregon and France, so with this note we both alert the community to this persistent concern and provide an approach to correct the data in case of similar problems.
Validating the Rice neural network and the Wing Kp real‐time models
Authors: Bala Ramkumar , Reiff Patricia
Published: June 2014

The Rice neural network models of Kp have been running in real time at http://mms.rice.edu/realtime/forecast.html since October 2007; Dst and AE models were added to our operations in May 2010. All these models use the Boyle index as basis functions computed from ACE real time inputs. Later, two more driving functions were included in November 2012: (a) the “Ram” functions that had dynamic pressure term added to the Boyle index and (b) the Newell functions. The Wing models are a set of neural network‐based Kp forecast models adopted by NOAA/Space Weather Prediction Center in March 2011 to supersede the Costello Kp model. This study indicates that any of the three Rice neural net predictors had a better success rate than the Wing model in predicting Kp (r=0.828 with Boyle, r=0.843 with Ram, and r=0.820 with Newell for 1 h predictions; similarly, r=0.739, 0.769, and 0.755 for 3 h predictions) in real time. In a head‐to‐head challenge using harvested real‐time outputs between April 2011 and February 2013, the Rice Boyle Kp models predicted better than the Wing models (0.771 versus 0.714 for 1 h predictions and 0.770 versus 0.744 for 3 h predictions). In addition, Wing's prediction was missing more often than the Rice prediction (≈6% versus 4.6%), meaning it had less reliability. The Rice models also predict AE(r=0.811 with Boyle; 0.806 with Ram; 0.765 with Newell, and 0.743 with Boyle; 0.747 with Ram for 1 h and 3 h predictions) and pressure‐corrected Dst (r=0.790; 0.767, and 0.704, and r=0.795; 0.797 and 0.707 for 1 h and 3 h predictions).
Point Defect Engineering of High‐Performance Bismuth‐Telluride‐Based Thermoelectric Materials
Authors: Hu Lipeng , Zhu Tiejun , Liu Xiaohua , Zhao Xinbing
Published: June 2014

Developing high‐performance thermoelectric materials is one of the crucial aspects for direct thermal‐to‐electric energy conversion. Herein, atomic scale point defect engineering is introduced as a new strategy to simultaneously optimize the electrical properties and lattice thermal conductivity of thermoelectric materials, and (Bi,Sb)2(Te,Se)3 thermoelectric solid solutions are selected as a paradigm to demonstrate the applicability of this new approach. Intrinsic point defects play an important role in enhancing the thermoelectric properties. Antisite defects and donor‐like effects are engineered in this system by tuning the formation energy of point defects and hot deformation. As a result, a record value of the figure of merit ZT of ≈1.2 at 445 K is obtained for n‐type polycrystalline Bi2Te2.3Se0.7 alloys, and a high ZT value of ≈1.3 at 380 K is achieved for p‐type polycrystalline Bi0.3Sb1.7Te3 alloys, both values being higher than those of commercial zone‐melted ingots. These results demonstrate the promise of point defect engineering as a new strategy to optimize thermoelectric properties.
Understanding sickness presenteeism through the experience of immigrant workers in a context of economic crisis
Authors: Galon Tanyse , Briones‐Vozmediano Erica , Agudelo‐Suárez Andrés A. , Felt Emily B. , Benavides Fernando G. , Ronda Elena
Published: June 2014

Background

Previous economic recessions show that immigrant workers may experience longer periods of unemployment, a situation that may lead employees to presenteeism, the act of working in spite of a health problem. This study explored perceptions about the factors that lead to presenteeism in immigrant workers considering the context of economic crisis.

Methods

Six focus group discussions were held (February 2012), with men and women from Colombia, Ecuador, and Morocco (n = 44) living in Spain and selected by theoretical sample. A qualitative content analysis was performed.

Results

Four categories were identified as factors that influence the occurrence of presenteeism in a context of economic crisis: poor employment conditions, fear of unemployment, employer/employee relationship, and difficulties in finding temporary replacement workers. Furthermore, musculoskeletal, respiratory, and mental problems were related to presenteeism.

Conclusions

It is important to develop strategies to protect workers from negative working conditions that are associated with deterioration of health. Am. J. Ind. Med. 57:950–959, 2014. © 2014 Wiley Periodicals, Inc.
Evaluation of a pilot promotora program for Latino forest workers in southern Oregon
Authors: Bush Diane E. , Wilmsen Carl , Sasaki Timothy , Barton‐Antonio Dinorah , Steege Andrea L. , Chang Charlotte
Published: June 2014

Background

Forest work, an occupation with some of the highest injury and illness rates, is conducted primarily by Latino immigrant workers. This study evaluates a pilot program where promotoras (lay community health educators) provided occupational health and safety trainings for Latino forest workers.

Methods

Evaluation methods included a focus group, post‐tests, and qualitative feedback.

Results

Community capacity to address working conditions increased through (i) increased leadership and community access to information and resources; and (ii) increased worker awareness of workplace health and safety rights and resources. Fear of retaliation remains a barrier to workers taking action; nevertheless, the promotoras supported several workers in addressing‐specific workplace issues.

Conclusions

For working conditions to significantly improve, major structural influences need to be addressed. A long‐term, organizationally supported promotora program can play a key role in linking and supporting change at the individual, interpersonal and community levels, contributing to and supporting structural change.

Re‐examining astrophysical constraints on the dark matter model
Authors: Brooks Alyson
Published: June 2014

Recent high‐resolution simulations that include Cold Dark Matter (CDM) and baryons have shown that baryonic physics can dramatically alter the dark matter structure of galaxies. These results modify our predictions for observed galaxy evolution and structure. Given these updated expectations, it is timely to re‐examine observational constraints on the dark matter model. A few observations exist that may indirectly trace dark matter, and may help confirm or deny possible dark matter models. Warm Dark Matter (WDM) and Self‐Interacting Dark Matter (SIDM) are currently the favorite alternative models to CDM. Constraints on the WDM particle mass require it to be so heavy that WDM is nearly indistinguishable from CDM. The best observational test of SIDM is likely to be in the dark matter distribution of faint dwarf galaxies, but there is a lack of theoretical predictions for galaxy structure in SIDM that account for the role of baryons.
