Authors: Ganesh Hashwin , Noroozifar Meissam , Kerman Kagan
Published: December 2017

In this study, simultaneous electrochemical detection of ascorbic acid (AA), dopamine (DA), and uric acid (UA) was performed using a modified graphite paste electrode (MGPE) with epigallocatechin gallate (EGCG) and green tea (GT) powder. It was shown that the anodic peak current increased in comparison with that of the graphite paste electrode (GPE) in the cyclic voltammograms. The optimal pH for simultaneous determination of a quaternary mixture of AA–DA–UA was determined to be pH 2. The anodic peak potentials for a mixture containing AA–DA–UA were well separated from each other. The catalytic peak currents obtained at the surface of the MGPE/EGCG were linearly dependent on the AA, DA, and UA concentrations up to 23, 14, and 14 µM, respectively. The detection limits for AA, DA, and UA were 190, 90, and 70 nM, respectively. The analytical performance of this sensor has been evaluated for simultaneous detection of AA, DA, and UA in real samples. Finally, a modified electrode was prepared using GT and used for simultaneous determination of AA, DA, and UA. Based on the results, MPGE/GT showed two oxidation peaks at 0.43 and 0.6 V for DA and UA, respectively, without any oxidation peak for AA. The calibration curves at the surface of MGPE/GT were linear up to 14 µM with a detection limit of 0.18 and 0.33 µM for DA and UA, respectively. MGPEs provide a promising platform for the future development of sensors for multiplexed electrochemical detection of clinically important analytes.
Implementing Responsible Research and Innovation Practices in SMEs: Insights into Drivers and Barriers from the Austrian Medical Device Sector
Authors: Auer Alexander , Jarmai Katharina
Published: December 2017

This paper addresses the question of how Responsible Research and Innovation (RRI) can be implemented in Small and Medium-Sized Enterprises (SMEs). It builds on existing knowledge about RRI in business as well as on insights into motivations, drivers and barriers from the related fields of eco-innovation and sustainability innovation. Expert interviews with CEOs of SMEs in the Austrian medical device sector are analyzed to develop insights into the companies’ research and innovation activities and potential drivers and barriers for RRI. The findings support the assumption that SMEs are largely unaware of the RRI concept. At the same time, however, it is possible to identify current practices that already operationalize aspects of RRI. It is argued that SMEs could build upon existing practices to further develop ways of being responsible and that implementation of RRI should be in line with specific organizational and contextual factors.
RETRACTED: Modeling Spatial Distribution of Some Contamination within the Lower Reaches of Diyala River Using IDW Interpolation
Authors: Madhloom Huda , Al-Ansari Nadhir , Laue Jan , Chabuk Ali
Published: December 2017

The aim of this research was to simulate the water quality along the lower course of the Diyala River using Geographic Information Systems (GIS) techniques. For this purpose, the samples were taken at 24 sites along the study area. The parameters: total dissolved solids (T.D.S), total suspended solids (T.S.S), iron (Fe), copper (Cu), chromium (Cr), and manganese (Mn) were considered. Water samples were collected on a monthly basis for a duration of five years. The adopted analyzing approach was tested by calculating the mean absolute error (MAE) and the correlation coefficient (R) between observed water samples and predicted results. The result showed a percentage error less than 10% and significant correlation at R > 89% for all pollutant indicators. It was concluded that the accuracy of the applied model to simulate the river pollutants can decrease the number of monitoring station to 50%. Additionally, a distribution map for the concentrations’ results indicated that many of the major pollution indicators did not satisfy the river water quality standards.

Published: December 2017

(1) Background and (2) Methods: A 14-day in vivo, multitoxic (pure mycotoxins) rat experiment was conducted with zearalenone (ZEA; 15 μg/animal/day), deoxynivalenol (DON; 30 μg/animal/day) and fumonisin B1 (FB1; 150 μg/animal/day), as individual mycotoxins, binary (FD, FZ and DZ) and ternary combinations (FDZ), via gavage in 1 mL water boluses. (3) Results: Body weight was unaffected, while liver (ZEA↑ vs. DON) and kidney weight (ZEA↑ vs. FDZ) increased. Hepatocellular membrane lipid fatty acids (FAs) referred to ceramide synthesis disturbance (C20:0, C22:0), and decreased unsaturation (C22:5 n3 and unsat. index), mainly induced by DON and to a lesser extent by ZEA. The DON-FB1 interaction was additive on C20:0 in liver lipids. In renal phospholipids, ZEA had the strongest effect on the FA profile, affecting the saturated (C18:0) and many n6 FAs; ZEA was in an antagonistic relationship with FB1 (C18:0) or DON (C18:2 n6, C20:1 n9). Hepatic oxidative stress was the most expressed in FD (reduced glutathione and glutathione peroxidase), while the nephrotoxic effect was further supported by lipid peroxidation (malondialdehyde) in the DON treatment. (4) Conclusions: In vivo study results refer to multiple mycotoxin interactions on membrane FAs, antioxidants and lipid peroxidation compounds, needing further testing.
A Guideline for Successful Calibration and Uncertainty Analysis for Soil and Water Assessment: A Review of Papers from the 2016 International SWAT Conference
Authors: Abbaspour Karim , Vaghefi Saeid , Srinivasan Raghvan
Published: December 2017

Application of integrated hydrological models to manage a watershed’s water resources are increasingly finding their way into the decision-making processes. The Soil and Water Assessment Tool (SWAT) is a multi-process model integrating hydrology, ecology, agriculture, and water quality. SWAT is a continuation of nearly 40 years of modeling efforts conducted by the United States Department of Agriculture (USDA) Agricultural Research Service (ARS). A large number of SWAT-related papers have appeared in ISI journals, building a world-wide consensus around the model’s stability and usefulness. The current issue is a collection of the latest research using SWAT as the modeling tool. Most models must undergo calibration/validation and uncertainty analysis. Unfortunately, these sciences are not formal subjects of teaching in most universities and the students are often left to their own resources to calibrate their model. In this paper, we focus on calibration and uncertainty analysis highlighting some serious issues in the calibration of distributed models. A protocol for calibration is also highlighted to guide the users to obtain better modeling results. Finally, a summary of the papers published in this special issue is provided in the Appendix.

Authors: Yuan Shuai , Zeng Gui , Shi Miaomiao , Zhang Dianxiang
Published: December 2017

Premise of the study: Microsatellite primers were developed for Primula ovalifolia, a member of Primula section Petiolares (Primulaceae), to study the population genetics and species delimitation in this section.

Methods and Results: A total of 4753 markers were successfully designated from 5139 putative simple sequence repeat loci. We isolated 38 expressed sequence tag–simple sequence repeat markers from 220 selected marker sites and tested polymorphism in three populations of P. ovalifolia, one of P. tardiflora, and one of P. epilosa. The number of alleles per locus ranged from one to 19, and the observed and expected levels of heterozygosity varied from 0 to 0.938 and 0 to 0.915, respectively. Most of the loci could be successfully cross‐amplified in the two congeneric species.

Conclusions: These markers will be useful for further population genetic analysis and gene flow estimation of P. ovalifolia and its relatives.
IMPACT OF VARIABLE GEOMETRY MINIFLAPS ON SAILPLANE FLIGHT CHARACTERISTICS
Authors: LAUK Peep , SEEGEL Karl-Erik , TÄHEMAA Toivo
Published: December 2017

Miniflaps (also known as mini-TED, active Gurnay flaps, etc.) located at the wing trailing edge enable to increase wing lift and reduce the aerodynamic drag. Variable geometry miniflaps (VGMF) elaborated at the Estonian Aviation Academy enable to expand the wing area up to 6.5%, when extended, and, at the same time, deflect 16.7 degrees downwards. The use of VGMF is especially promising for reducing the airspeed and sink speed of modern high wing loading sailplanes flying in thermals. The VGMFs were built in cooperation with the Lithuanian company JSC “Sportine Aviacija ir Ko”. They were fixed inside the sailplane LAK-17B trailing flaps. During the test flights, the VGMF effect on the sailplane’s sink speed was measured at different airspeeds and different flap positions. The flight parameters were recorded electronically and later calculated for standard atmosphere. The method of parallel flight was used for comparison. The results indicate that with the flaps position at + 9 degrees, the CAS 79.5 km/h sink speed decreased 0.775–0.555  m/s, i.e. 39.6%. The sailplane’s wing loading was 39.4 kg/m 2. With the flaps position at + 15 degrees, the optimal airspeed decreased, but the sink speed, compared to the previous, rose. Cl max increased with the VGMF 1.41–1.58 (i.e. 12%).

Published: December 2017

L’Altipiano della Sila può essere considerato un “hotspot” di biodiversità, come dimostrano anche i riconoscimenti di organismi internazionali quali l’UNESCO. L’importanza di tale comprensorio è confermata anche dall’interessante fauna lepidotterologica ospitata, le cui conoscenze sono tuttavia per lo più relative a studi occasionali. Le formazioni forestali presenti in Sila, rappresentano ecosistemi particolarmente sensibili ai cambiamenti climatici, per questo è auspicabile la realizzazione di ricerche faunistiche a lungo termine su organismi bioindicatori. Nel presente lavoro vengono forniti i dati relativi ai primi due anni di campionamento (2014-2015) dei lepidotteri notturni eseguiti nell’Arboreto Sbanditi (Sila Grande) tramite una Rothamsted trap. Sono stati effettuati, con cadenza settimanale, 54 campionamenti a seguito dei quali si sono raccolti 3.622 esemplari appartenenti a 223 specie. La comunità a macrolepidotteri notturni è ben caratterizzata, con le specie più abbondanti legate ad habitat forestali, in particolar modo conifere. La fenologia della comunità ha mostrato una significativa variabilità tra i due anni, in relazione al diverso andamento stagionale delle temperature, a conferma dell’importanza che hanno le stazioni di campionamento a lungo termine nel descrivere le dinamiche di popolazione e gli effetti sulla fauna.

Published: December 2017

A wide range of rheumatic and peripheral nervous system disorders may develop in patients with HIV infection, leading to pain, sensory symptoms, and muscle weakness. Over the past three decades, the progress in management of HIV disease with anti-retroviral therapy (ART) has resulted in increased life expectancy for people living with HIV disease. With this new chronicity of the disease has a constellation of chronic musculoskeletal, orthopaedic and rheumatic manifestations has emerged, as potential complications of the disease itself and/or the results of ART treatment regimen and/or because of expected age-related symptoms/manifestations. The incidence of CTS in the general population is around 3.8% with clinical examination and, when electroneuromyography is used, it is 2.7%. In the HIV-positive population, the incidence is very close to that of the general population. The aim of this study was to evaluate the incidence of CTS and to identify factors influencing the development of CTS in HIV-infected patients attending our clinic. This syndrome has been associated with advanced HIV disease and the use of ART possibly due to an increased inflammatory state and the presence of concurrent HCV infection.

Published: December 2017

The aim was to evaluate the role of klotho in the pathogenesis of systemic sclerosis (SSc), through the measurement of its serum concentration in SSc patients compared to healthy controls, and to assess the association with cutaneous and visceral involvement. Blood samples obtained from both SSc patients and healthy controls were analysed by an ELISA assay for the detection of human klotho. SSc patients were globally evaluated for disease activity and assessed through the modified Rodnan’s Skin Score, Medsger’s scale, pulmonary function tests, 2D-echocardiography, nailfold capillaroscopy and laboratory tests. Our cohort consisted of 69 SSc patients (61 females, mean age 64.5±12.5 years, median disease duration 9.0 (IQR 8) years) and 77 healthy controls (28 females, mean age 49.7±10.2 years). In the group of SSc patients, 19 (27.5%) suffered from a diffuse form of SSc. All patients were receiving IV prostanoids, and some of them were concomitantly treated with immunosuppressive drugs (prednisone, hydroxychloroquine, mofetil mycophenolate, methotrexate, cyclosporin A and azathioprine). The median serum concentration of klotho was significantly lower in patients compared to controls (0.23 ng/mL vs 0.60 ng/mL; p<0.001). However, Spearman’s test showed no significant association between klotho serum levels and disease activity, concerning either clinical, laboratory or instrumental findings. Our data show a significant deficit of klotho in SSc patients although any significant association was detected between klotho serum concentration and the clinical, laboratory or instrumental features of the disease. However, due to the limits of the study, further investigations are required.
Pre-Service Teachers’ Beliefs about Foreign Language Learning: A Study of Three Different Teacher Training Study Programmes in Slovenia
Authors: Skubic Darija , Fojkar Mateja Dagarin
Published: December 2017

It has been determined that beliefs about language learning are significant for the learning and teaching process, and that learners may differ in their beliefs towards learning a new language. Similarly, student-teachers of different subjects may differ in their beliefs about language learning. The main aim of this study was thus to investigate pre-service preschool teachers’, primary school teachers’, and special education teachers’ beliefs about foreign language learning in Slovenia. Three different areas were researched more closely: beliefs about foreign language aptitude, beliefs about the nature of learning and beliefs about foreign language motivations and expectations. The BALLI questionnaire was used to gather data, with responses provided by170 first-year students. The results show that despite attending different teacher training study programmes, students do not differ significantly in their beliefs about language learning; however, in comparison to other studies, the results imply that learners from different cultures see language learning differently.
Bourgeois Tensions, Marxist Economics and Aphaeresis of Communal Spirit in Sembene Ousmane’s God’s Bits of Wood and Ngugi wa Thiong’o’s Devil on the Cross
Authors: Adeniyi Emmanuel Idowu
Published: December 2017

This article appraises the poetics of two of the foremost African creative writers whose literary sensibilities exhibit conspicuously Marxist conceptual models. The writers have poignantly deployed their creative ingenuities towards raising social consciousness against the bourgeois economy which imposes a politics of asymmetry, parasitism and stratification on the economic thought of the African society that once projected a communal spirit. Considering the precarious conditions of Africa’s economy due to the pernicious effects of capitalism, it is imperative to examine the sordidness of classism, alienated labour, commodification or thingification of the underclass and other bourgeois tensions in African literature, as portrayed by these writers. Marxist theoretical models of economic determinism and historical materialism are discussed as the simulacrum of Vilfredo Pareto’s 80/20 Rule or Pareto Principle. Though Marxists are fixated on revolution as the only solution to end the misery of the underclass and terminate the hegemony of the oligarchy that exploits sellers of labour, the paper advocates economic revivalism through the exploration of the opportunities offered by the communal mode of production.

Within the line of research in entrepreneurship and economic development that defends the entrepreneurial activity as a tool for job creation and activation of the economy, we will perform an empirical analysis in Spain of the relationship between the institutional environment, specifically the entrepreneurial finance variable , capital structure and growth of young firms. To this end, this study focuses on the business context of young Spanish SMEs and uses information from the GEM and SABI databases for the period 2008-2015. Using the panel data methodology, empirical evidence is provided that access to finance favors the indebtedness of young Spanish SMEs, and leverage is an explanatory factor of job creation. The data is consistent at the country and regional levels. Therefore, an institutional effort, both public and private, that facilitates financing entrepreneurs will favor the creation of employment and economic growth. The authors have contributed equally to this research.

Abstract. Since 1994, the In-service Aircraft for a Global Observing System (IAGOS) program has produced in situ measurements of the atmospheric composition during more than 51 000 commercial flights. In order to help analyze these observations and understand the processes driving the observed concentration distribution and variability, we developed the SOFT-IO tool to quantify source–receptor links for all measured data. Based on the FLEXPART particle dispersion model (Stohl et al., 2005), SOFT-IO simulates the contributions of anthropogenic and biomass burning emissions from the ECCAD emission inventory database for all locations and times corresponding to the measured carbon monoxide mixing ratios along each IAGOS flight. Contributions are simulated from emissions occurring during the last 20 days before an observation, separating individual contributions from the different source regions. The main goal is to supply added-value products to the IAGOS database by evincing the geographical origin and emission sources driving the CO enhancements observed in the troposphere and lower stratosphere. This requires a good match between observed and modeled CO enhancements. Indeed, SOFT-IO detects more than 95 % of the observed CO anomalies over most of the regions sampled by IAGOS in the troposphere. In the majority of cases, SOFT-IO simulates CO pollution plumes with biases lower than 10–15 ppbv. Differences between the model and observations are larger for very low or very high observed CO values. The added-value products will help in the understanding of the trace-gas distribution and seasonal variability. They are available in the IAGOS database via http://www.iagos.org. The SOFT-IO tool could also be applied to similar data sets of CO observations (e.g., ground-based measurements, satellite observations). SOFT-IO could also be used for statistical validation as well as for intercomparisons of emission inventories using large amounts of data.

Abstract. The nocturnal nitrogen oxides, which include the nitrate radical (NO3), dinitrogen pentoxide (N2O5), and its uptake product on chloride containing aerosol, nitryl chloride (ClNO2), can have profound impacts on the lifetime of NOx (= NO + NO2), radical budgets, and next-day photochemical ozone (O3) production, yet their abundances and chemistry are only sparsely constrained by ambient air measurements. Here, we present a measurement data set collected at a routine monitoring site near the Abbotsford International Airport (YXX) located approximately 30 km from the Pacific Ocean in the Lower Fraser Valley (LFV) on the West coast of British Columbia. Measurements were made from July 20 to August 4, 2012, and included mixing ratios of ClNO2, N2O5, NO, NO2, total odd nitrogen (NOy), O3, photolysis frequencies, and size distribution and composition of non-refractory submicron aerosol. At night, O3 was rapidly and often completely removed by dry deposition and by titration with NO of anthropogenic origin and unsaturated biogenic hydrocarbons in a shallow nocturnal inversion surface layer. The low nocturnal O3 mixing ratios and presence of strong chemical sinks for NO3 limited the extent of nocturnal nitrogen oxide chemistry at ground level. Consequently, mixing ratios of N2O5 and ClNO2 were low (
Planar seismic source characterization models developed for probabilistic seismic hazard assessment of Istanbul

Published: December 2017

Abstract. This contribution provides an updated planar seismic source characterization (SSC) model to be used in the probabilistic seismic hazard assessment (PSHA) for Istanbul. It defines planar rupture systems for the four main segments of the North Anatolian fault zone (NAFZ) that are critical for the PSHA of Istanbul: segments covering the rupture zones of the 1999 Kocaeli and Düzce earthquakes, central Marmara, and Ganos/Saros segments. In each rupture system, the source geometry is defined in terms of fault length, fault width, fault plane attitude, and segmentation points. Activity rates and the magnitude recurrence models for each rupture system are established by considering geological and geodetic constraints and are tested based on the observed seismicity that is associated with the rupture system. Uncertainty in the SSC model parameters (e.g., b value, maximum magnitude, slip rate, weights of the rupture scenarios) is considered, whereas the uncertainty in the fault geometry is not included in the logic tree. To acknowledge the effect of earthquakes that are not associated with the defined rupture systems on the hazard, a background zone is introduced and the seismicity rates in the background zone are calculated using smoothed-seismicity approach. The state-of-the-art SSC model presented here is the first fully documented and ready-to-use fault-based SSC model developed for the PSHA of Istanbul.
Modern methods for investigating the stability of a pitching floating platform wind turbine
Authors: Lennie Matthew , Marten David , Pechlivanoglou George , Nayeri Christian Navid , Paschereit Christian Oliver
Published: December 2017

Abstract. The QBlade implementation of the lifting-line free vortex wake (LLFVW) method was tested in conditions analogous to floating platform motion. Comparisons against two independent test cases using a variety of simulation methods show good agreement in thrust forces, rotor power, blade forces and rotor plane induction. Along with the many verifications already undertaken in the literature, it seems that the code performs solidly even in these challenging cases. Further to this, the key steps are presented from a new formulation of the instantaneous aerodynamic thrust damping of a wind turbine rotor. A test case with harmonic platform motion and collective blade pitch is used to demonstrate how combining such tools can lead to a better understanding of aeroelastic stability. A second case demonstrates a non-harmonic blade pitch manoeuvre showing the versatility of the instantaneous damping method.

Published: December 2017

Embora as estradas rurais permitam o desenvolvimento das comunidades rurais, elas alteram a resposta hidrológica natural da bacia hidrográfica. Esse estudo foi realizado na bacia do Rio Guabiroba, Guarapuava-PR, com o objetivo de identificar e caracterizar os tipos de interceptação de fluxo subsuperficial causados por cortes de estradas rurais associados à sua distribuição espacial ao longo da bacia hidrográfica. Para tanto, como metodologia utilizada foram realizados levantamentos de campo com observação direta para determinar as áreas de interceptação do fluxo em subsuperfície e sua distribuição na bacia do Rio Guabiroba. Três tipos principais foram identificados e denominados como: fluxo de retorno, fluxo pipe e fluxo insaturado. O fluxo de retorno é frequentemente distribuído próximo aos rios e no fundo de vale, o fluxo pipe está presente principalmente em média vertente, e o fluxo insaturado ocorre mais frequentemente em encostas superiores, expelido nos taludes mais profundos. Conclui-se, portanto, que os tipos de interceptação subsuperficial e a distribuição espacial desses podem alterar a dinâmica hidrológica natural da bacia, provocando um tempo de resposta menor que por meio da infiltração e deslocamento no solo.Palavras-chave: Bacia hidrográfica rural, resposta hidrológica, conectividade, área saturada.

O artigo coteja as pinturas rupestres piauienses com algumas interpretações das imagens pré-históricas desenvolvidas no âmbito da História da Arte. Para isso, recupera o sistema taxonômico elaborado por Niède Guidon (1985; 1989), observando aí a presença de algumas noções postas à prova pela produção artística moderna e contemporânea. O questionamento do enquadramento convencional da História da Arte motiva também uma reconsideração do conceito de arte a partir dos registros rupestres piauienses. Por fim, frente à inadequação dos pares conceituais encontrados na área – em especial, a oposição entre naturalismo e geometrismo – propõe-se uma leitura das imagens piauienses enquanto escrituras multinaturalistas, conforme a noção concebida por Eduardo Viveiros de Castro (2015). AbstractThe article contrasts Piauí’s rock paintings with some interpretations of the prehistoric images found within the context of the History of Art.

The management of complex cartilage and meniscal pathology in young, athletic patients is extremely challenging. Joint preservation surgery is most difficult in patients with concomitant knee pathologies, including cartilage defects, meniscal deficiency, malalignment, and/or ligamentous insufficiency. Clinical decision making for these patients is further complicated by articular cartilage lesions, which often are incidental findings; therefore, treatment decisions must be based on the confirmed contribution of articular cartilage lesions to symptomatology. Surgical management of any of the aforementioned knee pathologies that is performed in isolation typically results in acceptable patient outcomes; however, concomitant procedures for the management of concomitant knee pathologies often are essential to the success of any single procedure. The use of biologic therapy as an alternative to or to augment more conventional surgical management has increased in popularity in the past decade, and indications for biologic therapy continue to evolve. Orthopaedic surgeons should understand knee joint preservation techniques, including biologic and reconstructive approaches in young, high-demand patients.
Profiles of Pre-service Teacher Education: An Investigation into the Nature of Selected Exemplary Programs in Jamaica and Michigan
Authors: Smith-Sherwood Heather
Published: December 2017

This qualitative multi-case study investigated thre exemplary pre-service teacher education programs in Jamaica and Michigan in order to provide an account of how they are structured in different contexts of tertiary institutions and, to identify how they ensure that their graduates are prepared to function effectively in today’s schools. Five categories of stakeholders across the three institutions were interviewed regarding their perception and expectations of pre-service teacher education in general as well as in the context of their program. The responses from these persons were described in narrative form, then analyzed and compared based on the similarities and differences that existed among them. The analysis led to the emergence of various themes across the three institutions, and these were used to draw conclusions relative to the structure of pre-service teacher education. The findings revealed eight distinguishing features of exemplary/effective pre-service teacher education programs whether university or college-based. (a) coherent program vision (b) cultural competence (c) collaborative partnership (d) contextualization (e) quality standards (f) well-planned and implemented field experiences (g) continuous assessment (h) experienced committed faculty and (i) a harmonious blend of theory and practice. To be effective, pre-service teacher education programs must prepare prospective teachers to adequately meet the challenges of teaching in today’s classrooms. To effect change, quality teachers are needed, and to produce quality teachers, quality preparation is a necessity.
Desigualdad y segmentación en los mercados de trabajo de España y Argentina
Authors: López-Roldán Pedro , Fachelli Sandra
Published: December 2017

La finalidad de este artículo es construir un modelo de segmentación general para analizar las desigualdades sociales en el mercado de trabajo y plantear la comparación de una tipología de posiciones o segmentos de empleo entre España y Argentina. Partiendo de una perspectiva no ortodoxa y definiendo las dimensiones que afectan la configuración de diversos segmentos de trabajo y empleo, presentamos los resultados de una investigación planteando el doble objetivo de construir un modelo de análisis para explicar la persistencia de las desigualdades en el mercado de trabajo y realizar un estudio comparado de las desigualdades en el mercado de trabajo mostrando sus similitudes y diferencias. Las realidades culturales e históricas de ambos países nos llevan a pensar, ante todo, que hablamos de contextos sociales muy distintos, no obstante, el análisis realizado permite corroborar nuestra hipótesis general que establece que no existe un único mercado de trabajo que ajusta oferta y demanda, que, por el contrario, se diferencia una tríada de segmentos que estructuran posiciones jerárquicas en el mercado laboral en correspondencia con ciertos perfiles específicos de la oferta de trabajo: género, edad, origen inmigrante o niveles educativos, que siguen un patrón general similar en ambos países.
Ni escuela, ni trabajo: el tiempo libre como un oasis obligado en medio de la nada
Authors: Moreno-Colom Sara , Borràs Català Vicent , Trinidad Jiménez Albert
Published: December 2017

El artículo presenta parte de los resultados del proyecto EJECT “La empleabilidad de l@s jóvenes: formación, género y territorio” financiado por el Plan Estatal de Investigación Científica, Técnica y de Innovación 2013-2016 (Ref. CSO2014-59753-P). En concreto, esta investigación se pregunta hasta qué punto las consecuencias de la crisis de la ocupación (con altas tasas de paro, inactividad y precariedad) están sustrayendo peso al trabajo productivo en el proyecto vital de los jóvenes. Este artículo se plantea que la pérdida de centralidad del empleo repercute en la identidad masculina, sobre todo, en los jóvenes con niveles bajos de cualificación que se sienten expulsados del sistema educativo y consideran poco atractivo el mercado laboral. La hipótesis de partida plantea que los jóvenes atribuirían a las actividades de ocio el peso de la identidad personal, especialmente los hombres. De manera que estas actividades, desarrolladas al margen de la formación o el trabajo remunerado, representarían un espacio de confort para los jóvenes. A partir de estos planteamientos, se propone una estrategia metodológica cualitativa. Los resultados apuntan que el tiempo libre emerge como un oasis obligado en medio de la nada: confiere identidad social cuando el sistema educativo te expulsa y el mercado de trabajo resulta poco atractivo.

MAQUIAVEL: A FORÇA, O PODER E A RETÓRICA
Authors: Adverse Helton
Published: December 2017

Resumo: O presente artigo visa examinar as relações entre poder, força e retórica no pensamento de Maquiavel. A obra do secretário florentino nos liberta da ilusão segundo a qual o poder é idêntico à força, nos mostrando que seu exercício é impossível sem a dimensão discursiva. Apenas levando esse fato em consideração, podemos apreender a realidade política em sua complexidade.

Everyone’s Invited: A Website Usability Study Involving Multiple Library Stakeholders
Authors: Azadbakht Elena , Blair John , Jones Lisa
Published: December 2017

This article describes a usability study of the University of Southern Mississippi Libraries’ website conducted in early 2016. The study involved six participants from each of four key user groups – undergraduate students, graduate students, faculty, and library employees – and consisted of six typical library search tasks such as finding a book and an article on a topic, locating a journal by title, and looking up hours of operation. Library employees and graduate students completed the study’s tasks most successfully, whereas undergraduate students performed fairly simple searches and relied on the Libraries’ discovery tool, Primo. The study’s results identified several problematic features that impacted each user group, including library employees. This increased internal buy-in for usability-related changes in a later website redesign.
The linguistics in othering: Teacher educators’ talk about cultural diversity
Authors: Nilsen Anne Birgitta , Fylkesnes Sandra , Mausethagen Sølvi
Published: December 2017

‘Othering’ can be conceptually defined as the manner in which social group dichotomies are represented in language via binary oppositions of ‘us’ and ‘them’. The article aims to contribute to a methodological approach for differentiating the concept of othering in educational settings. We will introduce new ways of conceptualising othering based on findings from an empirical critical discourse analytical study of how teacher educators talk about the term ‘cultural diversity’. The study is based on transcriptions of interviews with Norwegian teacher educators. The findings illustrate that teacher educators talk about cultural diversity using seven different ways of othering. These ways of othering are important because teacher educators’ discourses influence preservice teachers, in turn, influencing their future teaching in schools. We argue that a critical linguistic awareness of the ways in which pupils are ‘othered’ is an important tool in counteracting social exclusion and promoting social justice and equity.

The Malayan pangolin (Manis javanica) is an unusual, scale-covered, toothless mammal that specializes in myrmecophagy. Due to their threatened status and continuing decline in the wild, concerted efforts have been made to conserve and rescue this species in captivity in China. Maintaining this species in captivity is a significant challenge, partly because little is known of the molecular mechanisms of its digestive system. Here, the first large-scale sequencing analyses of the salivary gland, liver and small intestine transcriptomes of an adult M. javanica genome were performed, and the results were compared with published liver transcriptome profiles for a pregnant M. javanica female. A total of 24,452 transcripts were obtained, among which 22,538 were annotated on the basis of seven databases. In addition, 3,373 new genes were predicted, of which 1,459 were annotated. Several pathways were found to be involved in myrmecophagy, including olfactory transduction, amino sugar and nucleotide sugar metabolism, lipid metabolism, and terpenoid and polyketide metabolism pathways. Many of the annotated transcripts were involved in digestive functions: 997 transcripts were related to sensory perception, 129 were related to digestive enzyme gene families, and 199 were related to molecular transporters. One transcript for an acidic mammalian chitinase was found in the annotated data, and this might be closely related to the unique digestive function of pangolins. These pathways and transcripts are involved in specialization processes related to myrmecophagy (a form of insectivory) and carbohydrate, protein and lipid digestive pathways, probably reflecting adaptations to myrmecophagy. Our study is the first to investigate the molecular mechanisms underlying myrmecophagy in M. javanica, and we hope that our results may play a role in the conservation of this species.
Autophagy Caught in the Act: A Supramolecular FRET Pair Based on an Ultrastable Synthetic Host–Guest Complex Visualizes Autophagosome–Lysosome Fusion

Published: December 2017

A supramolecular FRET pair based on the ultrahigh binding affinity between cyanine 3 conjugated cucurbit[7]uril (CB[7]‐Cy3) and cyanine 5 conjugated adamantylamine (AdA‐Cy5) was exploited as a new synthetic tool for imaging cellular processes in live cells. Confocal laser scanning microscopy revealed that CB[7]‐Cy3 and AdA‐Cy5 were intracellularly translocated and accumulated in lysosomes and mitochondria, respectively. CB[7]‐Cy3 and AdA‐Cy5 then formed a host–guest complex, reported by a FRET signal, as a result of the fusion of lysosomes and mitochondria. This observation not only indicated that CB[7] forms a stable complex with AdA in a live cell, but also suggested that this FRET pair can visualize dynamic organelle fusion processes, such as those involved in the degradation of mitochondria through autophagy (mitophagy), by virtue of its small size, chemical stability, and ease of use.
