Do Consumers Want More Nutritional and Health Information on Wine Labels? Insights from the EU and USA
Authors: Annunziata Azzurra , Pomarici Eugenio , Vecchio Riccardo , Mariani Angela
Published: July 2016

The global strategy to reduce the harmful use of alcohol launched in 2010 by the World Health Organization includes, amongst several areas of recommended actions, providing consumer information about, and labelling, alcoholic beverages to indicate alcohol-related harm. Labelling requirements worldwide for alcoholic drinks are currently quite diverse and somewhat limited compared to labelling on food products and on tobacco. In this context, the current paper contributes to the academic and political debate on the inclusion of nutritional and health information on wine labelling, providing some insights into consumer interest in, and preferences for, such information in four core wine-producing and -consuming countries: Italy, France, Spain, and the United States of America. A rating-based conjoint analysis was performed in order to ascertain consumer preferences for different formats of additional information on wine labels, and a segmentation of the sample was performed to determine the existence of homogeneous groups of consumers in relation to the degrees of usefulness attached to the nutritional and health information on wine labels. Our results highlight the interest expressed by European and United States consumers for introducing nutrition and health information on wine labels. However, the results of conjoint analysis show some significant differences among stated preferences of the information delivery modes in different countries. In addition, segmentation analysis reveal the existence of significant differences between consumer groups with respect to their interest in receiving additional information on wine labels. These differences are not only linked to the geographic origin of the consumers, or to socio-demographic variables, but are also related to wine consumption habits, attitudes towards nutritional information, and the degree of involvement with wine. This heterogeneity of consumer preferences indicates a need for a careful consideration of wine labelling regulations and merits further investigation in order to identify labelling guidelines in terms of the message content and presentation method to be used.
Recent Advances in Room Temperature, High-Power Terahertz Quantum Cascade Laser Sources Based on Difference-Frequency Generation
Authors: Lu Quanyong , Razeghi Manijeh
Published: July 2016

We present the current status of high-performance, compact, THz sources based on intracavity nonlinear frequency generation in mid-infrared quantum cascade lasers. Significant performance improvements of our THz sources in the power and wall plug efficiency are achieved by systematic optimizing the device’s active region, waveguide, and chip bonding strategy. High THz power up to 1.9 mW and 0.014 mW for pulsed mode and continuous wave operations at room temperature are demonstrated, respectively. Even higher power and efficiency are envisioned based on enhancements in outcoupling efficiency and mid-IR performance. Our compact THz device with high power and wide tuning range is highly suitable for imaging, sensing, spectroscopy, medical diagnosis, and many other applications.
Lead–Lag Relationship Using a Stop-and-Reverse-MinMax Process
Authors: Maier-Paape Stanislaus , Platen Andreas
Published: July 2016

The intermarket analysis, in particular the lead–lag relationship, plays an important role within financial markets. Therefore, a mathematical approach to be able to find interrelations between the price development of two different financial instruments is developed in this paper. Computing the differences of the relative positions of relevant local extrema of two charts, i.e., the local phase shifts of these price developments, gives us an empirical distribution on the unit circle. With the aid of directional statistics, such angular distributions are studied for many pairs of markets. It is shown that there are several very strongly correlated financial instruments in the field of foreign exchange, commodities and indexes. In some cases, one of the two markets is significantly ahead with respect to the relevant local extrema, i.e., there is a phase shift unequal to zero between them.
Effectiveness of Four Disinfectants against Ebola Virus on Different Materials
Authors: Smither Sophie , Phelps Amanda , Eastaugh Lin , Ngugi Sarah , O’Brien Lyn , Dutch Andrew , Lever Mark
Published: July 2016

The West Africa Ebola virus (EBOV) outbreak has highlighted the need for effective disinfectants capable of reducing viral load in a range of sample types, equipment and settings. Although chlorine-based products are widely used, they can also be damaging to equipment or apparatus that needs continuous use such as aircraft use for transportation of infected people. Two aircraft cleaning solutions were assessed alongside two common laboratory disinfectants in a contact kill assay with EBOV on two aircraft relevant materials representative of a porous and non-porous surface. A decimal log reduction of viral titre of 4 is required for a disinfectant to be deemed effective and two of the disinfectants fulfilled this criteria under the conditions tested. One product, Ardrox 6092, was found to perform similarly to sodium hypochlorite, but as it does not have the corrosive properties of sodium hypochlorite, it could be an alternative disinfectant solution to be used for decontamination of EBOV on sensitive apparatus.
Development of polymorphic microsatellite markers for Japanese yew, Taxus cuspidata, and T. cuspidata var. nana (Taxaceae)
Authors: Kondo Toshiaki
Published: July 2016

Premise of the study:

Taxus cuspidata (Taxaceae), which is well known for the effective anticancer metabolite paclitaxel (e.g., taxol), is an evergreen needle‐leaved tree widely distributed in eastern Eurasia including Japan. We developed 15 microsatellite markers from this species and confirmed their utility for the dwarf variety nana, which is common in alpine regions along the Sea of Japan.

Methods and Results:

Thirteen polymorphic loci were characterized for genetic variation in three populations of T. cuspidata. The number of alleles per locus ranged from 11 to 31, with an average of 18.5; the expected heterozygosity ranged from 0.78 to 0.95, with an average of 0.89. All loci were successfully amplified in T. cuspidata var. nana and showed high polymorphism.

Conclusions:

These markers will be useful for investigating speciation and range formation of T. cuspidata in Japan, and the results will provide crucial information for the conservation of Taxus species.
3,6-Carbazole vs 2,7-carbazole: A comparative study of hole-transporting polymeric materials for inorganic–organic hybrid perovskite solar cells
Authors: Li Wei , Otsuka Munechika , Kato Takehito , Wang Yang , Mori Takehiko , Michinobu Tsuyoshi
Published: July 2016

The ever increasing demand for clean energy has encouraged researchers to intensively investigate environmentally friendly photovoltaic devices. Inorganic–organic hybrid perovskite solar cells (PSCs) are very promising due to their potentials of easy fabrication processes and high power conversion efficiencies (PCEs). Designing hole-transporting materials (HTMs) is one of the key factors in achieving the high PCEs of PSCs. We now report the synthesis of two types of carbazole-based polymers, namely 3,6-Cbz-EDOT and 2,7-Cbz-EDOT, by Stille polycondensation. Despite the same chemical composition, 3,6-Cbz-EDOT and 2,7-Cbz-EDOT displayed different optical and electrochemical properties due to the different connectivity mode of the carbazole unit. Therefore, their performances as hole-transporting polymeric materials in the PSCs were also different. The device based on 2,7-Cbz-EDOT showed better photovoltaic properties with the PCE of 4.47% than that based on 3,6-Cbz-EDOT. This could be due to its more suitable highest occupied molecular orbital (HOMO) level and higher hole mobility.
Ring-whizzing in polyene-PtL2 complexes revisited
Authors: Oloba-Whenu Oluwakemi A , Albright Thomas A , Soubra-Ghaoui Chirine
Published: July 2016

Ring-whizzing was investigated by hybrid DFT methods in a number of polyene–Pt(diphosphinylethane) complexes. The polyenes included cyclopropenium+, cyclobutadiene, cyclopentadienyl+, hexafluorobenzene, cycloheptatrienyl+, cyclooctatetraene, octafluorooctatetraene, 6-radialene, pentalene, phenalenium+, naphthalene and octafluoronaphthalene. The HOMO of a d10 ML2 group (with b2 symmetry) interacting with the LUMO of the polyene was used as a model to explain the occurrence of minima and maxima on the potential energy surface.
IMPRINTS OF ELECTRON–POSITRON WINDS ON THE MULTIWAVELENGTH AFTERGLOWS OF GAMMA-RAY BURSTS
Authors: Geng J. J. , Wu X. F. , Huang Y. F. , Li L. , Dai Z. G.
Published: July 2016

Optical rebrightenings in the afterglows of some gamma-ray bursts (GRBs) are unexpected within the framework of the simple external shock model. While it has been suggested that the central engines of some GRBs are newly born magnetars, we aim to relate the behaviors of magnetars to the optical rebrightenings. A newly born magnetar will lose its rotational energy in the form of Poynting-flux, which may be converted into a wind of electron–positron pairs through some magnetic dissipation processes. As proposed by Dai, this wind will catch up with the GRB outflow and a long-lasting reverse shock (RS) would form. By applying this scenario to GRB afterglows, we find that the RS propagating back into the electron–positron wind can lead to an observable optical rebrightening and a simultaneous X-ray plateau (or X-ray shallow decay). In our study, we select four GRBs (i.e., GRB 080413B, GRB 090426, GRB 091029, and GRB 100814A), of which the optical afterglows are well observed and show clear rebrightenings. We find that they can be well interpreted. In our scenario, the spin-down timescale of the magnetar should be slightly smaller than the peak time of the rebrightening, which can provide a clue to the characteristics of the magnetar.
THE EFFECTS OF THE LOCAL ENVIRONMENT AND STELLAR MASS ON GALAXY QUENCHING TO z ∼ 3
Authors: Darvish Behnam , Mobasher Bahram , Sobral David , Rettura Alessandro , Scoville Nick , Faisst Andreas , Capak Peter
Published: July 2016

We study the effects of the local environment and stellar mass on galaxy properties using a mass complete sample of quiescent and star-forming systems in the COSMOS field at

. We show that at

the median star formation rate (SFR) and specific SFR (sSFR) of all galaxies depend on the environment, but they become independent of the environment at z ≳ 1. However, we find that only for star-forming galaxies, the median SFR and sSFR are similar in different environments regardless of redshift and stellar mass. We find that the quiescent fraction depends on the environment at z ≲ 1 and on stellar mass out to z ∼ 3. We show that at z ≲ 1 galaxies become quiescent faster in denser environments and that the overall environmental quenching efficiency increases with cosmic time. Environmental and mass quenching processes depend on each other. At z ≲ 1 denser environments more efficiently quench galaxies with higher masses (log(

) ≳ 10.7), possibly due to a higher merger rate of massive galaxies in denser environments. We also show that mass quenching is more efficient in denser regions. We show that the overall mass quenching efficiency (

) for more massive galaxies (log(

) ≳ 10.2) rises with cosmic time until z ∼ 1 and then flattens out. However, for less massive galaxies, the rise in

continues to the present time. Our results suggest that environmental quenching is only relevant at z ≲ 1 and is likely a fast process, whereas mass quenching is the dominant mechanism at z ≳ 1 with a possible stellar feedback physics.
COLLIMATION AND ASYMMETRY OF THE HOT BLAST WAVE FROM THE RECURRENT NOVA V745 Sco

Published: July 2016

The recurrent symbiotic nova V745 Sco exploded on 2014 February 6 and was observed on February 22 and 23 by the Chandra
X-ray Observatory Transmission Grating Spectrometers. By that time the supersoft source phase had already ended, and Chandra spectra are consistent with emission from a hot, shock-heated circumstellar medium with temperatures exceeding 107 K. X-ray line profiles are more sharply peaked than expected for a spherically symmetric blast wave, with a full width at zero intensity of approximately 2400 km s−1, an FWHM of 1200 ± 30 km s−1, and an average net blueshift of 165 ± 10 km s−1. The red wings of lines are increasingly absorbed toward longer wavelengths by material within the remnant. We conclude that the blast wave was sculpted by an aspherical circumstellar medium in which an equatorial density enhancement plays a role, as in earlier symbiotic nova explosions. Expansion of the dominant X-ray-emitting material is aligned close to the plane of the sky and is most consistent with an orbit seen close to face-on. Comparison of an analytical blast wave model with the X-ray spectra, Swift observations, and near-infrared line widths indicates that the explosion energy was approximately 1043 erg and confirms an ejected mass of approximately 10−7
M
⊙. The total mass lost is an order of magnitude lower than the accreted mass required to have initiated the explosion, indicating that the white dwarf is gaining mass and is a Type Ia supernova progenitor candidate.
MODELING THE AFTERGLOW OF THE POSSIBLE FERMI-GBM EVENT ASSOCIATED WITH GW150914
Authors: Morsony Brian J. , Workman Jared C. , Ryan Dominic M.
Published: July 2016

We model the possible afterglow of the Fermi Gamma-ray Burst Monitor (GBM) event associated with LIGO detection GW150914, under the assumption that the gamma-rays are produced by a short GRB-like relativistic outflow. We model GW150914-GBM as both a weak, on-axis short GRB and normal short GRB seen far off-axis. Given the large uncertainty in the position of GW150914, we determine that the best chance of finding the afterglow is with ASKAP or possibly the Murchinson Widefield Array (MWA), with the flux from an off-axis short GRB reaching 0.2–4 mJy (0.12–16 mJy) at 150 MHz (863.5 MHz) by 1–12 months after the initial event. At low frequencies, the source would evolve from a hard to soft spectrum over several months. The radio afterglow would be detectable for several months to years after it peaks, meaning the afterglow may still be detectable and increasing in brightness NOW (2016 mid-July). With a localization from the MWA or ASKAP, the afterglow would be detectable at higher radio frequencies with the ATCA and in X-rays with Chandra or XMM.
PROBING TRAPPIST-1-LIKE SYSTEMS WITH K2
Authors: Demory Brice-Olivier , Queloz Didier , Alibert Yann , Gillen Ed , Gillon Michael
Published: July 2016

The search for small planets orbiting late M dwarfs holds the promise of detecting Earth-size planets for which their atmospheres could be characterized within the next decade. The recent discovery of TRAPPIST-1 entertains hope that these systems are common around hosts located at the bottom of the main sequence. In this Letter, we investigate the ability of the repurposed Kepler mission (K2) to probe planetary systems similar to TRAPPIST-1. We perform a consistent data analysis of 189 spectroscopically confirmed M5.5 to M9 late M dwarfs from Campaigns 1–6 to search for planet candidates and inject transit signals with properties matching TRAPPIST-1b and c. We find no transiting planet candidates across our K2 sample. Our injection tests show that K2 is able to recover both TRAPPIST-1 planets for 10% of the sample only, mainly because of the inefficient throughput at red wavelengths resulting in Poisson-limited performance for these targets. Increasing injected planetary radii to match GJ 1214b’s size yields a recovery rate of 70%. The strength of K2 is its ability to probe a large number of cool hosts across the different campaigns, out of which the recovery rate of 10% may turn into bona fide detections of TRAPPIST-1-like systems within the next two years.
De la définition linguistique du nom propre
Authors: Vaxelaire Jean-Louis
Published: July 2016

« Même les enfants savent ce qu'est un nom propre ! », peut-on parfois entendre. Pourtant, les querelles entre linguistes sont nombreuses et tel nom sera classé dans les noms propres dans un article et dans les noms communs dans un autre. Ce travail tente de cerner les divergences de vue, particulièrement liées à des questions mal réglées d'interdisciplinarité, et de comprendre à quoi peut correspondre une définition linguistique du nom propre, i.e.  délestée des considérations uniquement référentielles héritées des théories logiques et centrée sur les textes. C'est à cette condition qu'il est possible d'observer les noms propres sous un nouvel angle.
Les liens faibles du crime en ligne
Authors: Dupont Benoit
Published: July 2016

Le dilemme de la confiance auquel sont confrontés les délinquants en ligne est souvent sous-estimé par ceux qui étudient les transformations que la révolution numérique a provoquées sur la criminalité. Pourtant, dans un contexte où une diversité d’expertises techniques et organisationnelles doit converger afin de mener des projets lucratifs, les liens de confiance jouent un rôle déterminant permettant d’écarter les partenaires à la fiabilité douteuse et de stabiliser les collaborations afin d’améliorer la performance criminelle. À travers deux études de cas portant sur un réseau de hackers démantelé au Québec en 2008 et le principal forum de discussion de pirates informatiques observés pendant 27 mois de 2009 à 2011, cet article illustre les défis concrets auxquels les cybercriminels sont confrontés dans l’attribution et le maintien de la confiance à des pairs qui ont de nombreuses raisons de faire défection sans risques de sanctions. La nature fragile et éphémère des liens de confiance est notamment analysée, ainsi que le rôle joué par des normes culturelles transgressives qui empêchent les communautés de hackers de profiter pleinement des avantages des outils de gestion automatisée des réputations.
Résoudre des crimes en ligne
Authors: Myles David , Millerand Florence , Benoit-Barné Chantal
Published: July 2016

Le développement des technologies numériques participe à l’émergence de nouveaux types d’initiatives citoyennes de sécurité. Cet article explore quatre formes de contribution en ligne de citoyens en matière de gouvernement du crime issues des sciences sociales et humaines : le travail de surveillance non institutionnalisée, le crowdsourced policing , les online vigilantes et la civilian police . Les enjeux soulevés par chacune de ces formes de contribution sont mobilisés pour mettre en lumière les résultats d’une démarche d’observation exploratoire au sein du Reddit Bureau of Investigation, un forum Internet anglophone qui regroupe des citoyens dont l’objectif est la résolution de crimes. Les résultats témoignent du rôle clé des technologies numériques et de surveillance dans l’émergence de ces pratiques, de nouvelles conceptions du rôle du citoyen en matière de gouvernement du crime, de la construction d’une identité commune en réaction à la figure du vigilante et du déploiement d’une expertise profane d’investigation.
Plaisanteries d’initiés
Authors: Ink Marion
Published: July 2016

Cet article vise à définir, par induction analytique à partir de matériaux recueillis depuis plus de 4 ans dans des résidences universitaires en France, aux États-Unis et au Canada, ce qu’est une plaisanterie d’initiés. Les plaisanteries d’initiés , objet principal de la présente étude, sont le résultat d’une filature d’interactions antérieures. Nous montrons ici que celles-ci sont toujours déclenchées par une situation absurde désamorcée par le rire des initiés in situ ou a posteriori . Elles sont alors activées et réactivées par les initiés en présence d’un public. Nous définissons ainsi les initiés comme les personnes présentes lors de la situation absurde et participant explicitement à la ou aux situations de désamorçage par le rire. Leur statut d’initiés leur autorise trois actions : répéter la plaisanterie devant un public, exprimer explicitement la compréhension de la plaisanterie (si elle est dite par un autre initié) et négocier avec les autres initiés l’inclusion d’un membre encore fluctuant. Cet article vise alors à distinguer les moqueries (rire excluant) des « taquineries » (rire intégrateur) dans le cadre des plaisanteries d’initiés. Les membres initiés des groupes ne sont pas seulement des personnes qui connaissent l’origine de la référence passée, mais celles et ceux qui ont partagé l’expérience émotionnelle du désamorçage par le rire.
Production of Nonadhesive Eggs by Flathead Chub and Implications for Downstream Transport and Conservation
Authors: Bestgen Kevin R. , Crockett Harry J. , Haworth Matthew R. , Fitzpatrick Ryan M.
Published: July 2016

Plains stream fishes in North America, including flathead chub Platygobio gracilis, are negatively affected by stream-flow alterations and fragmentation, and limited information on egg type and reproductive strategy hinders their conservation. On the basis of several lines of evidence, including laboratory culture, observations of reproduction in captivity, and capture and rearing of eggs from Fountain Creek, Colorado, we report that flathead chub produce nonadhesive eggs. Flathead chub eggs are relatively small at 2.3 mm mean diameter, have a greater yolk-to-egg volume ratio and thus sink faster, and take longer to hatch, compared with nonadhesive eggs from pelagic spawning species. Flathead chub are also longer lived compared with pelagic spawning species and the wider variety of habitat types they occupy may influence upstream egg retention. Although spawning mode (e.g., pelagic, lithopelagic, other) is incompletely known for flathead chub, habitat needs in terms of flows and reach lengths suitable for reproduction and recruitment may vary with habitat type but may be similar to that for other pelagic spawning species. Accommodating specialized reproductive life histories of fishes, including egg type and transport characteristics, in stream conservation planning may assist with maintaining or enhancing populations of all Great Plains cyprinids, including increasingly rare flathead chub.
Descriptive Epidemiology for Turtles Admitted to the North Carolina State University College of Veterinary Medicine Turtle Rescue Team

Published: July 2016

The North Carolina State University College of Veterinary Medicine Turtle Rescue Team has been treating and releasing wild turtles since 1996 and has compiled a collection of almost 4,000 medical records, now available for consultation by researchers via the North Carolina State University Libraries Special Collections Research Center. Data available for each case include county where turtle was discovered, patient identification number, admission date, species, sex and reproductive status, physical examination findings, clinical diagnosis, last case-entry date, length of stay, and final disposition. Additional data in the records include a day-by-day description of treatment and husbandry performed for each turtle. This report summarizes 2,613 turtle cases examined between 1996 and 2012 by the Turtle Rescue Team, including 12 native species of turtle from 63 North Carolina counties. The sex distribution of those of known sex were evenly distributed. The most common presenting condition was vehicular trauma while garden equipment and fish-equipment–related trauma, pet surrender, and other human-induced injury represented an additional 154 cases. Animal attacks and trauma due to unknown causes were also represented. Other conditions diagnosed on presentation included infection, aural abscessation, nutritional disorder, neurologic disorder, buoyancy disorder, prolapse, and other. A small number of turtles were not diagnosed or were healthy. Ultimate disposition data were available for 2,318 turtles, of which 1,227 were released to the wild. The epidemiological data presented here are similar to information collected in Illinois, Tennessee, and Virginia. Medical records from wildlife hospitals and primary care facilities represent an important opportunity to gain valuable insight into the epidemiology of human interaction with native wildlife species.
Apprentissage et durabilité : quelle place donner au jeu et au « rejeu » dans l’apprentissage et la mémorisation d’une langue/culture cible ?
Authors: Dubrac Anne-Laure
Published: July 2016

En nous appuyant sur la théorie de Marcel Jousse, nous avons tenté de mettre en évidence les liens existant entre « action gestuelle » et mémorisation dans l’apprentissage à long terme d’une langue cible (ici l’anglais dans la filière Droit). Pour ce faire, nous avons mené une expérimentation à partir de l’analyse d’extraits provenant d’un documentaire portant sur le procès OJ Simpson. Les séquences étudiées ont été l’occasion de « rejeux-verbo-gestuels » ; autrement dit, elles ont permis aux étudiants de donner corps, par le biais d’une théâtralisation, à des formes linguistiques entendues.
Language Sustainability and the Theory of Multiple Intelligences
Authors: Molaie Sayena
Published: July 2016

A student’s level of achievement is not solely influenced by the way he/she is taught, but by a nest of correlations, resulting in each individual being influenced by an immediate and a proximal environment. The human capability to act effectively in a nest of correlations constitutes the modern definition of intelligence (Barrington 2007: 423) and precisely Gardner’s Multiple Intelligences Theory (MIT). This article reflects on the results of a pilot study, carried out to investigate whether there is a relationship between MIT and language sustainability among learners taking an English course. 220 second-year science students were randomly chosen for two experimental groups (MIT-based teaching) and a control group (teaching based on their textbook). The main results showed a statistically significant difference between students’ continuous assessment marks. Also, the results of students’ final exam showed a statistically significant difference between the experimental and control groups.
« Loin des yeux, loin du cœur » : La condition des personnes privées de liberté dans le conflit syrien
Authors: Lucas Rachel
Published: July 2016

Le 3 février 2016, le Conseil des droits de l’homme de l’O.N.U. a émis un rapport ayant trait à la condition des individus privés de liberté en Syrie. Accablant l’ensemble des parties au conflit (gouvernementales ou non), le rapport fait état d’actes de torture, de privations arbitraires de liberté et d’une kyrielle d’exactions à l’encontre des personnes détenues. Le droit applicable aux conflits armés non internationaux semble donc demeurer lettre morte dans ce conflit désormais quinquennal et il est plus qu’incertain que les recommandations du Conseil parviennent à améliorer cet état de fait.
Protein Translation Activity: A New Measure of Host Immune Cell Activation
Authors: Seedhom Mina O. , Hickman Heather D. , Wei Jiajie , David Alexandre , Yewdell Jonathan W.
Published: July 2016

We describe the in vivo ribopuromycylation (RPM) method, which uses a puromycin-specific Ab to fluorescently label ribosome-bound puromycylated nascent chains, enabling measurement of translational activity via immunohistochemistry or flow cytometry. Tissue staining provides a unique view of virus-induced activation of adaptive, innate, and stromal immune cells. RPM flow precisely quantitates virus-induced activation of lymphocytes and innate immune cells, and it provides a unique measure of immune cell deactivation and quiescence. Using RPM we find that high endothelial cells in draining lymph nodes rapidly increase translation in the first day of vaccinia virus infection. We also find a population of constitutively activated splenic T cells in naive mice and further that most bone marrow T cells activate 3 d after vaccinia virus infection. Bone marrow T cell activation is nonspecific, IL-12–dependent, and induces innate memory T cell phenotypic markers. Thus, RPM measures translational activity to uniquely identify cell populations that participate in the immune response to pathogens, other foreign substances, and autoantigens.
Structure of the Adenovirus Type 4 (Species E) E3-19K/HLA-A2 Complex Reveals Species-Specific Features in MHC Class I Recognition
Authors: Li Lenong , Santarsiero Bernard D. , Bouvier Marlene
Published: July 2016

Adenoviruses (Ads) subvert MHC class I Ag presentation and impair host anti-Ad cellular activities. Specifically, the Ad-encoded E3-19K immunomodulatory protein targets MHC class I molecules for retention within the endoplasmic reticulum of infected cells. We report the x-ray crystal structure of the Ad type 4 (Ad4) E3-19K of species E bound to HLA-A2 at 2.64-Å resolution. Structural analysis shows that Ad4 E3-19K adopts a tertiary fold that is shared only with Ad2 E3-19K of species C. A comparative analysis of the Ad4 E3-19K/HLA-A2 structure with our x-ray structure of Ad2 E3-19K/HLA-A2 identifies species-specific features in HLA-A2 recognition. Our analysis also reveals common binding characteristics that explain the promiscuous, and yet high-affinity, association of E3-19K proteins with HLA-A and HLA-B molecules. We also provide structural insights into why E3-19K proteins do not associate with HLA-C molecules. Overall, our study provides new information about how E3-19K proteins selectively engage with MHC class I to abrogate Ag presentation and counteract activation of CD8+ T cells. The significance of MHC class I Ag presentation for controlling viral infections, as well as the threats of viral infections in immunocompromised patients, underline our efforts to characterize viral immunoevasins, such as E3-19K.
Leadership, job satisfaction and intention to leave among registered nurses in the North West and Free State provinces of South Africa
Authors: Sojane Jeremia S. , Klopper Hester C. , Coetzee Siedine K.
Published: July 2016

Background: The nurse leadership of a hospital is identified as the single most important aspect of the practice environment that impacts nurse outcomes. When nurses are satisfied with their jobs, they tend to remain with their employers and become more productive in their workplaces.Objectives: This study aimed to investigate the relationship between leadership, job satisfaction and intentions to leave among registered nurses (RNs) working in hospitals in the North West and Free State provinces of South Africa.Methods: A cross-sectional survey design was adopted. The population (N = 680) with the sample (n = 204) included RNs in medical–surgical units in both private and public hospitals in the two provinces. Data were collected using the RN4CAST questionnaire.Results: RNs were satisfied with the items pertaining to leadership except for praise and recognition (55.7%). They also indicated high levels of overall job satisfaction (70.5%) but were dissatisfied with wages (50%), study leave (40.9%) and opportunities for advancement (40.1%). Furthermore, 46.1% of the RNs intended to leave their current hospitals. The results indicated a relationship between leadership and job satisfaction (r = 0.47; p = 0.00) and between intention to leave and job satisfaction (d = 0.50).Conclusion: The nurse managers played a significant role influencing RN’s level of job satisfaction, while job satisfaction was highly correlated with intention to leave. The nurse leadership can improve job satisfaction by giving praise and recognition to the RNs for jobs well done, and RNs should be afforded the opportunity to advance their careers through further studies.Keywords: Leadership,  job satisfaction, intention to leave, Nurse

Published: July 2016

El proceso de construcción del Espacio Europeo de Educación Superior (EEES) ha supuesto una nueva organización de las enseñanzas universitarias en sus diferentes niveles, con un cambio en la orientación de la enseñanza, pasando de centrarnos en el aprendizaje de contenidos, a una orientación completamente diferente basada en resultados de aprendizaje y desarrollo de competencias. La carrera de diseño forma a profesionales en la vertiente científica y técnica para el desarrollo de nuevos diseños y productos desde la generación de las ideas, la producción, la fabricación y el posterior lanzamiento, incluido el estudio del impacto ambiental al final de su vida útil. La asignatura de Economía de la Empresa adquiere una condición muy relevante como complemento de la formación técnica que reciben los alumnos de este grado. La observación crítica de la situación de la docencia de empresa, ha llevado a platear un proyecto de innovación docente que dé respuesta a las necesidades de aprendizaje en emprendimiento, a la vez que atiende los problemas de docencia, y se incorporan las competencias transversales CT-4 “Innovación, creatividad y emprendimiento”, y CT-6 “Trabajo en equipo y liderazgo”. Consideradas como fundamentales en el desempeño de la gestión empresarial. También las competencias CT-03 “Análisis y resolución de problemas”, y CT-12 “Planificación y gestión del tiempo” que favorezcan un mejor proceso de aprendizaje.

Las rúbricas de evaluación son guías de puntuación que bien elaboradas ofrecen al profesorado unas ventajas a la hora de calificar. En nuestra experiencia hemos diseñado una rúbrica para evaluar trabajos en grupo y hemos analizado las calificaciones obtenidas, desglosadas por apartados y comparándolas con el peso otorgado a cada apartado dentro de la rúbrica. La finalidad de este estudio era analizar si la rúbrica diseñada era discriminatoria, así como detectar los puntos débiles de la misma para reflexionar sobre las mejoras que se le podrían practicar. Los resultados mostraron un amplio abanico de calificaciones evaluando con la rúbrica diseñada. El 80% de la rúbrica contó con descriptores bien definidos y del 20% restante, un 10% fue evaluado por los alumnos y el otro 10% resultó demasiado subjetivo por no tener bien definidos los criterios de evaluación, considerándose éste un punto débil de la misma y susceptible de mejora. En términos generales, la rúbrica utilizada ofreció notas discriminatorias entre grupos demostrando la idoneidad de su diseño.

Este artculo desarrolla un estudio estadstico a partir de un experimentorealizado en dos escuelas universitarias de la Universitat Politecnica deValencia. El objetivo principal del estudio es cuanticar como la distanciade los alumnos al profesor y la pizarra en el aula afecta a su rendimientoacademico. Un segundo objetivo pretende determinar si trabajar en parejao de manera individual tambien afecta al rendimiento. En el experimentohemos recogido y procesado informacion sobre la posicion exacta de cadaalumno en el aula y en el laboratorio durante dos cursos academicos.Tambien se registro cada cambio de posicion, as como sus notas en diferentesexamenes, cursos y asignaturas tanto de teora como de practicas.Nuestro experimento ha producido gran cantidad de datos que han sidoanalizados usando metodos estadsticos avanzados como ANOVA, el testHSD post-hoc de Tukey, y el test de Mantel basado en el coeciente decorrelacion producto-momento de Pearson.
Un enfoque diferente para la resolución de problemas

Published: July 2016

En las asignaturas en las que está involucrada la capacidad de resolución de problemas resulta fundamental que los alumnos desarrollen la habilidad de entender los enunciados de los problemas. Se ha detectado que el alumnado en general tiene carencias en la comprensión de textos, particularmente de enunciados de problemas. En nuestro caso concreto, se ha propuesto una metodología para los alumnos que cursan asignaturas de estadística en grados de ingeniería, de modo que les facilite una lectura crítica de estos enunciados, pero teniendo en cuenta que el objetivo de las asignaturas no es que aprendan a ‘leer’, sino estadística. Se ofertó como una actividad voluntaria con el incentivo de poder ganar una nota adicional que les permitiese aumentar la calificación obtenida mediante las vías tradicionales. La respuesta por parte del alumnado se consideró positiva, por lo que se va a repetir el esfuerzo en los próximos cursos. Además, se integró con otras metodologías innovadoras que fomentaban competencias genéricas tales como la comunicación oral y escrita en la propia lengua, así como en otra lengua extranjera (en este caso, el inglés).

Published: July 2016

En los últimos años, screencast se ha utilizado ampliamente como herramienta de enseñanza en diferentes áreas. Un screencast es un video corto obtenido a partir de la captura de la pantalla del ordenador acompañada de la narración de un profesor. Este trabajo explora la opinión de los estudiantes de primer curso de Universidad en relación con los beneficios que el uso de screencast aporta a la mejora del aprendizaje de la física, con el uso que los estudiantes hacen del screencast, y también por qué deciden usarlo o no. Se han preparado y subido a la plataforma, varios screencasts en los que se tratan aspectos clave de la física en los que es sabido que los estudiantes encuentran dificultades. Sakai/PoliformaT es una plataforma de aprendizaje desarrollada en la Universitat Politècnica de València (UPV, www.upv.es/index-en.htm), a través del proyecto Sakai (https://sakaiproject.org). En promedio, cada screencast fue visionado más de 100 veces, por estudiantes de un grupo de física de 117 alumnos. Trabajos previos sugieren que screencast es percibido por los alumnos como beneficioso y concluyen que se obtienen mejoras en el aprendizaje. Para verificar esta percepción, se realizó una encuesta anónima que constaba de 10 preguntas de respuesta múltiple y una pregunta abierta. Se analizó la relación entre el uso de los screencast y la percepción de los estudiantes de haber obtenido beneficios en cuanto a una mejor comprensión de la materia tratada. También se analizó la relación entre el uso de screencast y la nota en preguntas relacionadas de un examen. Los resultados indican que la mayoría de los estudiantes opinan que los screencast son útiles para su aprendizaje ayudándoles a comprender conceptos relevantes y mejorando así sus resultados.

Authors: Blanco-Alcántara David , García-Villafranca Borja
Published: July 2016

En esta investigación se describe un proyecto en el que se pone en práctica una herramienta de intercambio en el entorno educativo, en concreto una  Moneda Social y Complementaria. La finalidad, con una serie de preguntas previas y otras posteriores al uso de la moneda, es poder evaluar  si se han cumplido una serie de objetivos que se han marcado y que servirán para conocer su posible potencial como herramienta pedagógica. Estos objetivos cubren diferentes ámbitos, unos de corte social (como mejorar la relación entre alumnos), otros a nivel académico (como aumentar la cultura financiera y la motivación) y otros de fomento de la iniciativa individual y toma de decisiones. Se comprueba como tras su utilización, y teniendo en cuenta una serie de limitaciones, esta herramienta va a conseguir potenciar la mayoría de los objetivos propuestos y servirá de guía para futuras investigaciones.

Authors: García Fayos Beatriz , Sancho Fernández Maria , Arnal Arnal Jose Miguel
Published: July 2016

La seguridad industrial es una herramienta clave para el desarrollo de la actividad profesional del graduado en Ingeniería Química. Su enseñanza-aprendizaje debe ser integrada en el curriculum de la titulación bien de forma transversal o específica, y debe fomentar el razonamiento y pensamiento crítico así como la búsqueda de soluciones a problemas de seguridad reales a través de actividades prácticas y la aplicación de metodologías activas. El presente trabajo analiza los conocimientos de seguridad adquiridos por los alumnos de Ingeniería Química a corto y medio plazo así como la influencia del uso de metodologías activas, aprendizaje progresivo o  realización de prácticas en empresa como herramientas para la mejora de los resultados obtenidos. Se analiza la evolución a través de dos asignaturas de cuarto curso Procesos industriales y Seguridad Industrial. Los resultados muestran que la combinación de metodologías activas junto con un aprendizaje guiado incrementa significativamente el nivel de los resultados así como el aumento del tiempo de trabajo o el refuerzo de los conocimientos a través de asignaturas en distintos cursos académicos. Por último, resulta fundamental la motivación de los alumnos en la mejora de los resultados obtenidos ya que permite un aprendizaje efectivo de competencias para su vida profesional.

Published: July 2016

El área de la educación superior necesita nuevas implementaciones metodológicas que facilitan el aprendizaje activo. El presente documento pretende demostrar la experiencia desarrollada en el proyecto de innovación educativa y mejora, en las materias de construcción I y economía en el primer semestre del primer curso del Grado en Arquitectura Técnica (UPV), para el desarrollo de un Plan de Negocios en el sector de la construcción. La metodología utilizada se basa en las actividades de los proyectos, de manera que el alumno utiliza los conocimientos adquiridos de forma activa al desarrollo de un proyecto de interconexión de la competencia de los diferentes temas. Los resultados muestran que esta metodología ha permitido el conocimiento interdisciplinario de ambas materias. Esto permite que el conocimiento hermético “a priori” de las dos asignaturas, se puede entender y trabajar de manera conjunta, asimilando y aplicando los mismos conceptos. Gracias a ello, el rendimiento de los estudiantes ha sido más positivo debido a los conocimientos previos en la materia a tratar, y de su aplicación directa.
