Published: July 2016

‘Joe’ (Reg. No. CV‐1119, PI 676270) hard white winter wheat (Triticum aestivum L.) was developed at the Agricultural Research Center‐Hays, Kansas State University, and released by the Kansas Agricultural Experiment Station in 2015. Joe was selected from a single cross of KS04HW101‐3/KS04HW119‐3 made in 2005 at Hays, KS. The objective of this cross was to develop a hard white winter wheat cultivar with adaptation to dryland production in western Kansas. Joe was developed using a modified bulk breeding method. Joe is an F6–derived line with experimental number KS11HW39‐5‐4, and it was tested in yield trials from 2010 to 2015. Joe is medium late and medium tall with a medium high test weight and medium protein concentration. Its milling and baking quality is acceptable to good. Joe was released because of its high grain yield potential in western Kansas and its good resistance to stripe rust (caused by Puccinia striiformis f. sp. tritici Westend.), leaf rust (caused by P. triticina f. sp. tritici Ericks.), and Wheat streak mosaic virus.

Investigation of Fracturing Network Propagation in Random Naturally Fractured and Laminated Block Experiments
Authors: Wang Yu , Li Xiao , He Jianming , Zhao Zhiheng , Zheng Bo
Published: July 2016

Researchers have recently realized thatsilty laminas are very developed in naturally fractured continentalsedimentary formations in the Ordos Basin(China). Studies have shown that silty laminas are significant to improve the physical properties and gas storage capacity, and the natural fractures interact with the hydraulic fractures to maximize the fracture network during hydraulic fracturing. However, the influence of silty laminas withrandom fractures on the created hydraulic fracture networkis not well understood. Laboratory experiments are proposed to investigate the evolution of fracture networks in naturally fractured formations with model blocks that contain laminas and random fractures. The influence of dominating factors was studied and analyzed, with an emphasis on stress ratio, injection rate, and laminae strength. Macroscopic failure morphology descriptions combined with meso 3-D laser scanning techniques are both used to reveal the evolution of fracture networks. It is suggested that high injection rate, medium laminae strength, and low stress ratio tend to increase the stimulated reservoir volume (SRV). The interactions between the silty laminae and random natural fractures affect the effect of hydraulic fracturing effectiveness. This work strongly links the production technology and fracability evaluation in the continental shale formation. It can aid in the understanding and optimization of hydraulic fracturing simulations in silty laminae shale reservoirs.
Multi-Objective Optimal Sizing for Battery Storage of PV-Based Microgrid with Demand Response
Authors: Zhou Nan , Liu Nian , Zhang Jianhua , Lei Jinyong
Published: July 2016

In order to solve the influence of uncertain photovoltaic power (PV) on the stable operation of microgrid (MG), demand response (DR) and battery energy storage system (BESS) need to be introduced simultaneously into the operation optimal scheduling of PV-based microgrid (PV-MG). Therefore, it is of great significance for commercial investment decisions of PV-MG to consider the influence of DR on BESS optimal sizing. Under the peak-valley time-of-use (TOU) price, this paper builds cross-time DR models based on price elasticity matrix. Furthermore, through the introduction of DR and BESS into PV-MG scheduling optimization, the MG investment and benefit model is proposed. Considering the constraint condition such as co-ordination of supply and demand, electricity price elasticity and energy loss of storage system, the improved non-dominated sorting genetic algorithm II (NSGA-II) is utilized to solve the multi-objective optimal allocation model of the BESS with the target of maximum PV consumptive rate and annual net profits. The optimization method was applied to a PV-MG in Guangdong. Through the regulation and control effect of demand response and BESS on load distribution, the uncertainties PV power can be suppressed so as to improve the PV system consumptive level, which is of great guiding significance for BESS optimal sizing under this situation.
An Integer Linear Programming Model for an Ecovat Buffer
Authors: De Goeijen Gijs , Smit Gerard , Hurink Johann
Published: July 2016

An increase in the number of volatile renewables in the electricity grid enhances the imbalance of supply and demand. One promising candidate to solve this problem is to improve the energy storage. The Ecovat system is a new seasonal thermal energy storage system currently under development. In this paper, an integer linear programming model is developed to describe the behaviour and potential of this system. Furthermore, it is compared with a previously developed model, which is simplifying the behaviour of the Ecovat system much more, but is much less computationally expensive. It is shown that the new approach performs significantly better for several cases. For controlling a real Ecovat system in the future we may incorporate a number of improvements identified by our comparison analysis into the previously developed approach, which may help increase the quality of the obtained results without increasing the computational effort too much.
Robust Peak-Shaving for a Neighborhood with Electric Vehicles
Authors: Gerards Marco , Hurink Johann
Published: July 2016

Demand Side Management (DSM) is a popular approach for grid-aware peak-shaving. The most commonly used DSM methods either have no look ahead feature and risk deploying flexibility too early, or they plan ahead using predictions, which are in general not very reliable. To counter this, a DSM approach is presented that does not rely on detailed power predictions, but only uses a few easy to predict characteristics. By using these characteristics alone, near optimal results can be achieved for electric vehicle (EV) charging, and a bound on the maximal relative deviation is given. This result is extended to an algorithm that controls a group of EVs such that a transformer peak is avoided, while simultaneously keeping the individual house profiles as flat as possible to avoid cable overloading and for improved power quality. This approach is evaluated using different data sets to compare the results with the state-of-the-art research. The evaluation shows that the presented approach is capable of peak-shaving at the transformer level, while keeping the voltages well within legal bounds, keeping the cable load low and obtaining low losses. Further advantages of the methodology are a low communication overhead, low computational requirements and ease of implementation.
A Selection Method for Power Generation Plants Used for Enhanced Geothermal Systems (EGS)
Authors: Hu Kaiyong , Zhu Jialing , Zhang Wei , Lu Xinli
Published: July 2016

As a promising and advanced technology, enhanced geothermal systems (EGS) can be used to generate electricity using deep geothermal energy. In order to better utilize the EGS to produce electricity, power cycles’ selection maps are generated for people to choose the best system based on the geofluids’ temperature and dryness conditions. Optimizations on double-flash system (DF), flash-organic Rankine cycle system (FORC), and double-flash-organic Rankine cycle system (DFORC) are carried out, and the single-flash (SF) system is set as a reference system. The results indicate that each upgraded system (DF, FORC, and DFORC) can produce more net power output compared with the SF system and can reach a maximum net power output under a given geofluid condition. For an organic Rankine cycle (ORC) using R245fa as working fluid, the generated selection maps indicate that using the FORC system can produce more power than using other power cycles when the heat source temperature is below 170 °C. Either DF or DFORC systems could be an option if the heat source temperature is above 170 °C, but the DF system is more attractive under a relatively lower geofluid’s dryness and a higher temperature condition.

Authors: Seo Min-Seop , Kim Taeyeon , Hong Goopyo , Kim Hyungkeun
Published: July 2016

This study describes the environmental impact of the material production, transportation, and construction phases from the construction site perspective. CO2 emissions for each process were determined using the Korea Life Cycle Inventory Database (LCI DB) in the material production phase, and the actual amounts of oil consumption for transportation equipment were identified in the material transportation phase. Generally, the oil and electric energy consumed during the construction was evaluated by direct monitoring. Through the construction period and cost according to work type, a correlation with CO2 emissions was also investigated. In addition, CO2 emissions were examined through the system capacity and gross floor area for each work type. The calculations have shown that CO2 emissions from the material production phase constitute 93.4% of the total CO2 emissions. In addition, CO2 emissions from the material transportation and on-site construction account for 2.4% and 4.2% of the total CO2 emissions, respectively. This paper concludes that it is important to select appropriate input materials and resources for the reduction of CO2 emissions. Furthermore, the amount of CO2 emissions arising from the construction site was reduced by finding and practicing measures to reduce CO2 emissions for each process.

We present a novel remote test system, an integrated remote testing system requiring minimal technology support overhead, enabled by configurable analog–digital Integrated Circuits (IC) to create a simple interface for a wide range of experiments. Our remote test system requires no additional setup, resulting both from using highly configurable devices, as well as from the advancement of straight-forward digital interfaces (i.e., USB) for the resulting experimental system. The system overhead requirements require simple email handling, available over almost all network systems with no additional requirements. The system is empowered through large-scale Field Programmable Analog Array (FPAA) devices and Baseline Tool Framework (BTF), where we present a range of experimentally measured examples illustrating the range of user interfacing available for the remote user.

Authors: Su Mei-Ling , He Yu , Li Qi-Sen , Zhu Bang-Hao
Published: July 2016

Zicao (Lithospermum erythrorhizon) has been used in clinics as a traditional Chinese medicine for thousands of years. Acetylshikonin (AS) is the main ingredient of Zicao, Xinjiang, China. The objective of this study was to investigate the anti-obesity and anti-nonalcoholic fatty liver disease (NAFLD) efficacy of AS in a model of spontaneous obese db/db mice. Mice were divided into Wild Type (WT) groups and db/db groups, which received no treatment or treatment with 100 mg/kg/day clenbuterol (CL) hydrochloride or 540 mg/kg/day AS by oral gavage for eight weeks. The results provided the evidence that AS prevented obesity and NAFLD including reduction in body weight, food efficiency ratio, serum triglyceride (TG) and free fatty acid (FFA) levels in db/db mice. Administration of AS markedly suppressed the levels of hepatic alanine aminotransferase (ALT), aspartate aminotransferase (AST) and pro-inflammatory cytokines in treated groups when compared with that of db/db groups. Further investigation of the lipid synthesis-related protein using Western blotting revealed that hepatic protein expression of sterol regulatory element-binding protein-1 (SREBP-1), fatty acid synthetase (FAS) and 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) were significantly downregulated by AS treatment. These findings suggest that AS exerts anti-obesity and anti-NAFLD effects through the regulation of lipid metabolism and anti-inflammatory effects.

Authors: Babajide Mustapha Ismail , Saeed Faisal
Published: July 2016

Following the explosive growth in chemical and biological data, the shift from traditional methods of drug discovery to computer-aided means has made data mining and machine learning methods integral parts of today’s drug discovery process. In this paper, extreme gradient boosting (Xgboost), which is an ensemble of Classification and Regression Tree (CART) and a variant of the Gradient Boosting Machine, was investigated for the prediction of biological activity based on quantitative description of the compound’s molecular structure. Seven datasets, well known in the literature were used in this paper and experimental results show that Xgboost can outperform machine learning algorithms like Random Forest (RF), Support Vector Machines (LSVM), Radial Basis Function Neural Network (RBFN) and Naïve Bayes (NB) for the prediction of biological activities. In addition to its ability to detect minority activity classes in highly imbalanced datasets, it showed remarkable performance on both high and low diversity datasets.
Micromechanical Characterization of Polysilicon Films through On-Chip Tests
Authors: Mirzazadeh Ramin , Eftekhar Azam Saeed , Mariani Stefano
Published: July 2016

When the dimensions of polycrystalline structures become comparable to the average grain size, some reliability issues can be reported for the moving parts of inertial microelectromechanical systems (MEMS). Not only the overall behavior of the device turns out to be affected by a large scattering, but also the sensitivity to imperfections gets enhanced. In this work, through on-chip tests, we experimentally investigate the behavior of thin polysilicon samples using standard electrostatic actuation/sensing. The discrepancy between the target and actual responses of each sample has then been exploited to identify: (i) the overall stiffness of the film and, according to standard continuum elasticity, a morphology-based value of its Young’s modulus; (ii) the relevant over-etch induced by the fabrication process. To properly account for the aforementioned stochastic features at the micro-scale, the identification procedure has been based on particle filtering. A simple analytical reduced-order model of the moving structure has been also developed to account for the nonlinearities in the electrical field, up to pull-in. Results are reported for a set of ten film samples of constant slenderness, and the effects of different actuation mechanisms on the identified micromechanical features are thoroughly discussed.
Eigenspace-Based Generalized Sidelobe Canceler Beamforming Applied to Medical Ultrasound Imaging
Authors: Li Jiake , Chen Xiaodong , Wang Yi , Li Wei , Yu Daoyin
Published: July 2016

The use of a generalized sidelobe canceler (GSC) can significantly improve the lateral resolution of medical ultrasound systems, but the contrast improvement isn’t satisfactory. Thus a new Eigenspace-based generalized sidelobe canceler (EBGSC) approach is proposed for medical ultrasound imaging, which can improve both the lateral resolution and contrast of the system. The weight vector of the EBGSC is obtained by projecting the GSC weight vector onto a vector subspace constructed from the eigenstructure of the covariance matrix, and using the new weight vector instead of the GSC ones leads to reduced sidelobe level and improved contrast. Simulated and experimental data are used to evaluate the performance of the proposed method. The Field II software is applied to obtain the simulated echo data of scattering points and circular cysts. Imaging of scattering points show that EBGSC has the same full width at half maximum (FWHM) as GSC, while the lateral resolution improves by 35.3% and 52.7% compared with synthetic aperture (SA) and delay-and-sum (DS), respectively. Compared with GSC, SA and DS, EBGSC improves the peak sidelobe level (PSL) by 23.55, 33.11 and 50.38 dB, respectively. Also the cyst contrast increase by EBGSC was calculated as 16.77, 12.43 and 26.73 dB, when compared with GSC, SA and DS, respectively. Finally, an experiment is conducted on the basis of the complete echo data collected by a medical ultrasonic imaging system. Results show that the proposed method can produce better lateral resolution and contrast than non-adaptive beamformers.
Trans*+ing Classrooms: The Pedagogy of Refusal as Mediator for Learning
Authors: Miller sj
Published: July 2016

Gender and sexuality norms, conscribed under cis/heteropatriarchy, have established violent and unstable social and educational climates for the millennial generation of lesbian, gay, bisexual, transgender, intersex, agender/asexual, gender creative, and questioning youth. While strides have been made to make schools more supportive and queer inclusive, schools still struggle to include lesbian, gay, bisexual, transgender*+, intersex, agender/asexual, gender creative, queer and questioning (LGBT*+IAGCQQ)-positive curricula. While extensive studies must be done on behalf of all queer youth, this work specifically focuses on how to support classroom teachers to uptake and apply a pedagogy of refusal that attends to the most vulnerabilized population of queer youth to date, those that are trans*+. A pedagogy of refusal will be explored through an evolving theory of trans*+ness, then demonstrated through a framework for classroom application, followed by recommendations for change.

Published: July 2016

Chiral acrylic esters derived from biomass were developed as models to have a better insight in the aryl–vinyl π-stacking interactions. Quantum chemical calculations, NMR studies and experimental evidences demonstrated the presence of equilibriums of at least four different conformations: π-stacked and face-to-edge, each of them in an s-cis/s-trans conformation. The results show that the stabilization produced by the π–π interaction makes the π-stacked conformation predominant in solution and this stabilization is slightly affected by the electron density of the aromatic counterpart.

Published: July 2016

Leaf rust (caused by Puccinia triticina Erikss. [Pt]) is increasingly impacting durum wheat (Triticum turgidum L. var. durum) production with the recent appearance of races with virulence to widely grown cultivars in many durum producing areas worldwide. A highly virulent P. triticina race on durum wheat was recently detected in Kansas. This race may spread to the northern Great Plains, where most of the US durum wheat is produced. The objective of this study was to identify sources of resistance to several races from the United States and Mexico at seedling stage in the greenhouse and at adult stage in field experiments. Genome‐wide association study (GWAS) was used to identify single‐nucleotide polymorphism (SNP) markers associated with leaf rust response in a worldwide durum wheat collection of 496 accessions. Thirteen accessions were resistant across all experiments. Association mapping revealed 88 significant SNPs associated with leaf rust response. Of these, 33 SNPs were located on chromosomes 2A and 2B, and 55 SNPs were distributed across all other chromosomes except for 1B and 7B. Twenty markers were associated with leaf rust response at seedling stage, while 68 markers were associated with leaf rust response at adult plant stage. The current study identified a total of 14 previously uncharacterized loci associated with leaf rust response in durum wheat. The discovery of these loci through association mapping (AM) is a significant step in identifying useful sources of resistance that can be used to broaden the relatively narrow leaf rust resistance spectrum in durum wheat germplasm.

Single‐nucleotide polymorphisms (SNPs) represent natural DNA sequence variation. They can be used for various applications including the construction of high‐density genetic maps, analysis of genetic variability, genome‐wide association studies, and map‐based cloning. Here we report on transcriptome sequencing in the two forage grasses, meadow fescue (Festuca pratensis Huds.) and Italian ryegrass (Lolium multiflorum Lam.), and identification of various classes of SNPs. Using the Orthology Guided Assembly (OGA) strategy, we assembled and annotated a total of 18,952 and 19,036 transcripts for Italian ryegrass and meadow fescue, respectively. In addition, we used transcriptome sequence data of perennial ryegrass (L. perenne L.) from a previous study to identify 16,613 transcripts shared across all three species. Large numbers of intraspecific SNPs were identified in all three species: 248,000 in meadow fescue, 715,000 in Italian ryegrass, and 529,000 in perennial ryegrass. Moreover, we identified almost 25,000 interspecific SNPs located in 5343 genes that can distinguish meadow fescue from Italian ryegrass and 15,000 SNPs located in 3976 genes that discriminate meadow fescue from both Lolium species. All identified SNPs were positioned in silico on the seven linkage groups (LGs) of L. perenne using the GenomeZipper approach. With the identification and positioning of interspecific SNPs, our study provides a valuable resource for the grass research and breeding community and will enable detailed characterization of genomic composition and gene expression analysis in prospective Festuca × Lolium hybrids.
REDUCED ACTIVITY AND LARGE PARTICLES FROM THE DISINTEGRATING PLANET CANDIDATE KIC 12557548b
Authors: Schlawin E. , Herter T. , Zhao M. , Teske J. K. , Chen H.
Published: July 2016

The intriguing exoplanet candidate KIC 12557548b is believed to have a comet-like tail of dusty debris trailing a small rocky planet. The tail of debris scatters up to 1.3% of the stellar light in the Kepler observatory’s bandpass (0.42–0.9 μm). Observing the tail’s transit depth at multiple wavelengths can reveal the composition and particle size of the debris, constraining the makeup and lifetime of the sub-Mercury planet. Early dust particle size predictions from the scattering of the comet-like tail pointed toward a dust size of ∼0.1 μm for silicate compositions. These small particles would produce a much deeper optical transit depth than near-infrared transit depth. We measure a transmission spectrum for KIC 12557548b using the SpeX spectrograph (covering 0.8–2.4 μm) simultaneously with the MORIS imager taking r′ (0.63 μm) photometry on the Infrared Telescope Facility for eight nights and one night in H band (1.63 μm) using the Wide-field IR Camera at the Palomar 200 inch telescope. The infrared spectra are plagued by systematic errors, but we argue that sufficient precision is obtained when using differential spectroscopic calibration when combining multiple nights. The average differential transmission spectrum is flat, supporting findings that KIC 12557548b’s debris is likely composed of larger particles ≳0.5 μm for pyroxene and olivine and ≳0.2 μm for iron and corundum. The r′ photometric transit depths are all below the average Kepler value, suggesting that the observations occurred during a weak period or that the mechanisms producing optical broadband transit depths are suppressed.
A STUDY OF THE ELEMENTS COPPER THROUGH URANIUM IN SIRIUS A: CONTRIBUTIONS FROM STIS AND GROUND-BASED SPECTRA

Published: July 2016

We determine abundances or upper limits for all of the 55 stable elements from copper to uranium for the A1 Vm star Sirius. The purpose of the study is to assemble the most complete picture of elemental abundances with the hope of revealing the chemical history of the brightest star in the sky, apart from the Sun. We also explore the relationship of this hot metallic-line (Am) star to its cooler congeners, as well as the hotter, weakly- or non-magnetic Mercury-manganese (HgMn) stars. Our primary observational material consists of Hubble Space Telescope (HST) spectra taken with the Space Telescope Imaging Spectrograph in the ASTRAL project. We have also used archival material from the COPERNICUS satellite, and from the HST Goddard High-Resolution Spectrograph, as well as ground-based spectra from Furenlid, Westin, Kurucz, Wahlgren, and their coworkers, ESO spectra from the UVESPOP project, and NARVAL spectra retrieved from PolarBase. Our analysis has been primarily by spectral synthesis, and in this work we have had the great advantage of extensive atomic data unavailable to earlier workers. We find most abundances as well as upper limits range from 10 to 100 times above solar values. We see no indication of the huge abundance excesses of 1000 or more that occur among many chemically peculiar stars of the upper main sequence. The picture of Sirius as a hot Am star is reinforced.
DAMPING OF MAGNETOHYDRODYNAMIC TURBULENCE IN PARTIALLY IONIZED PLASMA: IMPLICATIONS FOR COSMIC RAY PROPAGATION
Authors: Xu Siyao , Yan Huirong , Lazarian A.
Published: July 2016

We study the damping processes of both incompressible and compressible magnetohydrodynamic (MHD) turbulence in a partially ionized medium. We start from the linear analysis of MHD waves, applying both single-fluid and two-fluid treatments. The damping rates derived from the linear analysis are then used in determining the damping scales of MHD turbulence. The physical connection between the damping scale of MHD turbulence and the cutoff boundary of linear MHD waves is investigated. We find two branches of slow modes propagating in ions and neutrals, respectively, below the damping scale of slow MHD turbulence, and offer a thorough discussion of their propagation and dissipation behavior. Our analytical results are shown to be applicable in a variety of partially ionized interstellar medium (ISM) phases and the solar chromosphere. The importance of neutral viscosity in damping the Alfvenic turbulence in the interstellar warm neutral medium and the solar chromosphere is demonstrated. As a significant astrophysical utility, we introduce damping effects to the propagation of cosmic rays in partially ionized ISM. The important role of turbulence damping in both transit-time damping and gyroresonance is identified.

Published: July 2016

Background

Gender-specific data on the management of HIV infection are scarce. Further, an increase in the proportion of new HIV diagnoses in older persons has been observed. Using data from the CoRIS cohort, we compared immunovirological responses and survival in HIV-infected men and women who started their first combination anti-retroviral therapy (cART) when aged </≥50 years.

Methods

We used multivariable logistic, linear and Cox regression, adjusting for potential confounders and including an interaction between age and sex, to assess differences in immunovirological responses and mortality, respectively.

Results

At 96 weeks, among subjects <50 years, women were less likely than men to achieve virological response (VR; adjusted OR [aOR] 0.77, 95% CI 0.60, 0.99) and among women, older individuals were more likely to achieve VR than the younger ones (aOR 1.96; 95% CI 1.15, 3.34). Initiating cART at ≥50 years was associated with lower increases in CD4+ T-cell count both in men (-65.8; 95% CI -91.3, -40.3) and women (-37.7; 95% CI -79.7, 4.4) and women showed higher increases than men in both subjects aged <50 (21.8; 95% CI -1.9, 45.5) and ≥50 years at cART initiation (49.9; 95% CI 19.9, 79.9). A higher risk of death in men ≥50 was observed (adjusted hazard ratio [aHR] 2.69; 95% CI 1.73, 4.21), but not in women (aHR 1.49; 95% CI 0.70, 1.14). Women experienced lower mortality than men <50 (0.66; 95% CI 0.41, 1.07) and in those ≥50 (0.37; 95% CI 0.14, 0.93).

Conclusions

Sex and age at cART initiation have a noticeable association with both virological and immunological responses and mortality. Age ≥50 is associated with poorer immunological response and higher mortality but this effect is less pronounced in women than in men.

Published: July 2016

This study was conducted to identify the effectiveness of an education program for evidence-based practice (EBP) implementation of clinical nursing. EBP knowledge/skill, attitude, and belief; information search ability; and EBP implementation were significantly higher in the experimental group than in the control group. Furthermore, the effect on implementation was maintained at week 4 and week 8, indicating that the education program practically promotes the EBP implementation of nurses. Results confirm that the education program for EBP implementation is critical and the continuous education program is an essential part of EBP implementation. Also, to promote EBP implementation and disseminate it to nursing organizations, an immediate concern should be the cultivation of mentors for EBP and fortification of the belief and ability regarding EBP implementation.

Published: July 2016

Gamification is being used in the business industry as a way to engage employees into achieving organizational goals, as well as incentivize customers to use their products. More recently, gamification has become a powerful instructional method in K-12 education, as well as top colleges and universities. Health care is still in the early stages of embracing gamification in education; however, some of this may be due to a knowledge deficit related to what gamification is and how it could be applied in the health care setting. This article describes the theory, components, applications, and benefits of gamification for educators who are interested in embarking on a new and innovative way of teaching.

En las páginas que siguen voy a proponer una reflexión sobre los dos conceptos fundamentales que guían esta sección: lo experimental y la colaboración. Me aproximaré a estos conceptos de forma consecutiva, primero el uno y después el otro, desde un punto de vista diferente al propuesto en la introducción: a partir del arte. Desde este ángulo, propongo algunas consideraciones más generales sobre las colaboraciones experimentales en antropología.
Diminutivos, hipocorísticos y otras formas de nombrar a los parientes en familias de Santiago de Chile
Authors: Gonzálvez Herminia
Published: July 2016

En este artículo se exponen resultados procedentes de una investigación antropológica titulada «Las familias en Chile: el trabajo de parentesco y la generación de constelaciones familiares». En concreto, en este trabajo se trata de dar respuesta a uno de los objetivos específicos de la investigación señalada, el cual consiste en mostrar cómo el trabajo de parentesco se relaciona con la forma de nombrar a los parientes. Para ello partimos de la definición de trabajo de parentesco de Di Leonardo definida como «la concepción, el mantenimiento y las celebraciones rituales a través de los lazos de parentesco dentro del grupo doméstico, incluyendo visitas, cartas, llamadas telefónicas, regalos y tarjetas recordatorias; la organización de las reuniones por vacaciones (...)» (1987: 442), para indagar cómo este trabajo repercute en las formas de nombrar. La metodología utilizada han sido las entrevistas en profundidad las cuales han permitido construir las cartas de parentesco de cada uno de los entrevistados/as. Como resultados encontramos que el uso de los diminutivos, los hipocorísticos y otras formas de nombrar son expresiones de ese trabajo de mantenimiento de los vínculos que se produce al interior de las familias el cual se encuentra influenciado por las posiciones de género y parentesco y las formas familiares que ocupan las personas entrevistadas.
Terence S. Turner (1935-2015)
Authors: Villarías-Robles Juan J. R.
Published: July 2016

El antropólogo estadounidense Terence S. Turner falleció en noviembre de 2015, dejando tras de sí una larga e intensa vida dedicada a la investigación sobre los pueblos originarios del Brasil y la Amazonía, en particular sobre los Cayapó. Le interesó tanto la reconstrucción de su cultura anterior al contacto con la frontera portuguesa y luego brasileña como el proceso de transformación que este contacto estimuló. En los primeros años de la década de 2000 participó activamente en la controversia desencadenada por la publicación del libro Darkness in El Dorado: How Scientists and Journalists Devastated the Amazon, de Patrick Tierney, acerca del impacto negativo sobre los Yanomami de ciertas formas de investigación científica practicadas en Occidente.
Mesures, développement : le statut de la créativité en question
Authors: Dirani Agathe
Published: July 2016

Les particularités inhérentes à la créativité en tant que compétence transversale, analysées à partir d’une revue de littérature en psychologie et sociologie sur la mesure, le développement et les effets de la créativité, semblent lui conférer un statut restreint au sein du système éducatif français. D’une part, les incertitudes autour des effets à long terme de la créativité, tout comme la logique adéquationniste structurant l’organisation scolaire, maintiennent cette compétence à l’écart des principales finalités assignées au système éducatif français. D’autre part, celui-ci n’est pas outillé pour la mesurer, étant donné que ses méthodes d’évaluation ne permettent pas d’appréhender cette compétence. Enfin, son développement y est nécessairement limité du fait des caractéristiques associées au curricula français et des interactions limitées entre les établissements scolaires et les autres espaces de socialisation contribuant à son développement.
Autonomie, responsabilité et coopération : ce qu’en disent les élèves utilisant un plan de travail
Authors: Connac Sylvain
Published: July 2016

L’outil d’enseignement « plan de travail », introduit par Helen Parkhurst au début du XXème siècle, est un document sur lequel chaque élève trouve des activités d’apprentissage à sa portée. Il permet à l’enseignant de prendre en compte la diversité de ses élèves. Si l’enseignant est sans cesse sollicité sur des problèmes très différents, il se sent très vite dépassé et a la tentation de revenir à une pédagogie traditionnelle, plus facile à gérer. Cette recherche s’est intéressée à l’opinion des élèves de cycle III d’école primaire qui pratiquent le plan de travail quotidiennement. Ils ont été interrogés via un questionnaire administré par leur enseignant. Plus de mille élèves français ont ainsi pu donner leur avis sur la nature de l’autonomie, la coopération entre pairs et les attitudes responsables que développe un plan de travail.
Histoire de l'exobiologie
Authors: Raulin-Cerceau Florence
Published: July 2016

L’essor de l’exploration spatiale dans le système solaire ainsi que le développement des recherches dans le domaine de l’origine de la vie sur Terre ont fourni les bases de l’exobiologie. En quelques décennies, ce champ pluridisciplinaire s’est considérablement élargi et structuré autour d’une large communauté de chercheurs. Par ailleurs, les découvertes d’exoplanètes, en particulier les « exo-terres » susceptibles d’être habitables, ont ouvert à d’autres perspectives. Ces avancées sont en voie de concrétiser l’une des quêtes les plus exaltantes de l’humanité : la recherche d’une autre vie dans l’univers.

A randomised controlled trial of ‘clockwise’ ultrasound for low back pain
Authors: Louw Adriaan , Zimney Kory , Landers Merrill R. , Luttrell Mark , Clair Bob , Mills Joshua
Published: July 2016

Aims: To examine how the choice of words explaining ultrasound (US) may influence the outcome of physiotherapy treatment for low back pain (LBP).Methods: Sixty-seven patients with LBP < 3 months were randomly allocated to one of three groups – traditional education about US (control group [CG]), inflated education about US (experimental group [EG]) or extra-inflated education about US (extra-experimental group [EEG]). Each patient received the exact same application of US that has shown clinical efficacy for LBP (1.5 Watts/cm2 for 10 minutes at 1 Megahertz, pulsed 20% over a 20 cm2 area), but received different explanations (CG, EG or EEG). Before and immediately after US,measurements of LBP and leg pain (numeric rating scale), lumbar flexion (distance to floor) and straight leg raise (SLR) (inclinometer) were taken. Statistical analysis consisted of mixed-factorial analyses of variance and chi-square analyses to measure differences between the three groups, as well as meeting or exceeding minimal detectable changes (MDCs) for pain, lumbar flexion and SLR.Results: Both EG and EEG groups showed a statistically significant improvement for SLR (p < 0.0001), while the CG did not. The EEG group participants were 4.4 times (95% confidence interval: 1.1 to 17.5) more likely to improve beyond the MDC than the CG. No significant differences were found between the groups for LBP, leg pain or lumbar flexion.Conclusion: The choice of words when applying a treatment in physiotherapy can alter the efficacy of the treatment.
Endothelial Nitric Oxide Synthase (–786T>C) and Endothelin-1 (5665G>T) Gene Polymorphisms as Vascular Dysfunction Risk Factors in Sickle Cell Anemia

Sickle cell anemia (SCA) patients have vascular complications, and polymorphisms in endothelin-1 ( ET-1) and endothelial nitric oxide synthase ( eNOS) genes were associated with ET-1 and nitric oxide disturbance. We investigate the association of ET-1 5665G>T and eNOS −786T>C polymorphisms with soluble adhesion molecules (sVCAM-1 and sICAM-1), biochemical markers, and medical history. We studied 101 SCA patients; carriers of eNOS minor allele (C) had the highest levels of sVCAM-1, and carriers of ET-1 minor allele had more occurrence of acute chest syndrome (ACS). The multivariate analysis suggested the influence of the ET-1 gene on ACS outcome and an association of the eNOS gene with upper respiratory tract infection. We suggest that eNOS and ET-1 gene polymorphisms can influence SCA pathophysiology and that eNOS variant in SCA patients might be important to nitric oxide activity and vascular alteration. We found an association of the ET-1 minor allele in ACS, showing the importance of genetic screening in SCA.
Izobrazba in inovativnost zaposlenih v slovenskih hotelskih organizacijah
Authors: Šuligoj Metod
Published: July 2016

Avtor želi v tem prispevku ugotoviti razlike v odnosu do inovativnosti med birokratskimi in nebirokratskimi hotelskimi organizacijami. Kot birokratske organizacije označi tiste, ki so uvedle standarde. Ločeno želi ugotoviti še, ali birokratske organizacije zaposlujejo bolj izobraženo delovno silo ali ne. V ta namen najprej opredeli osnovno terminologijo: hotelirstvo, inovativnost, birokracija in znanje na splošno ter v turizmu in hotelirstvu. Poudari, da se tudi vlada zaveda pomena inovativnosti v hotelirstvu (turizmu), zato izvaja številne ukrepe. V empiričnem delu s statističnimi metodami, kot sta deskriptivna analiza in Bonferronijev test, ugotovi, da statistično značilnih razlik med birokratskimi in nebirokratskimi hotelskimi organizacijami ni. To velja tako za inovativnost kot za izobrazbo zaposlenih. S tem avtor na podlagi znanstvenih metod ovrže pogosto napačno mnenje o vplivu birokracije na inovativnost.
Izobraževanje izobraževalcev odraslih temeljna naloga sodobne izobraževalne politike pri načrtovanju vseživljenjskega učenja
Authors: Žalec Natalija
Published: July 2016

V zadnjih nekaj letih v Evropi vse bolj glasno razmišljamo o izobraževanju izobraževalcev, a tokrat ne le o učiteljih v šolah, ampak širše - o izobraževalcih, ki delujejo zunaj šolskih programov izobraževanja, npr. na širokem področju poklicnega usposabljanja in spopolnjevanja, predvsem pa tudi tistih, ki delujejo na področju izobraževanja odraslih – tako v formalnem kot neformalnem. V razpravi se posvečamo predvsem usposabljanju in spopolnjevanju izobraževalcev odraslih v Sloveniji skozi ugotovite, do katerih so prišli raziskovalci v Evropi kot tudi v Sloveniji. Razpravljamo o njihovem položaju, vlogah in nalogah, o tem, kakšne kompetence potrebujejo in kakšne so njihove izobraževalne potrebe.

Published: July 2016

Namen prispevka je predstaviti pomen izobraževanja mentorjev za praktično usposabljanje študentov na Filozofski fakulteti Univerze v Ljubljani. Sprva bodo kronološko, od leta 2004 do 2010, prikazani projekti, v okviru katerih je potekalo to izobraževanje, in razlogi za njihovo izvedbo. Seznanili se bomo z dvema vrstama izobraževanja mentorjev: za področje pedagoških in nepedagoških študijskih programov. Sledil bo prikaz rezultatov izobraževanja mentorjev med letoma 2007 in 2010 na področju nepedagoških študijskih programov, v okviru katerega so se izobraževali mentorji iz različnih delovnih organizacij, ki sprejemajo študente s Filozofske fakultete in tudi drugih fakultet na praktično usposabljanje. Omenili bomo pričakovanja mentorja glede izobraževanja, uporabna znanja in njihove predloge o vrednotenju mentorjev na praktičnem usposabljanju ter njihova priporočila za ureditev sistema mentorstva.
