El presente trabajo se centra en el estudio del papel que juega el control visual del espacio en las prácticas sociales de las comunidades prehistóricas. Este trabajo se articula a partir de un estudio de caso, el término municipal de Calviá, situado en el sureste de la isla de Mallorca, para analizar las diferentes formas de monumentalidad arquitectónica y cómo estas se constituyen cómo un punto de referencia social dentro del paisaje. Partiendo de una amplia horquilla temporal, que abarcaría el Bronce Naviforme (1550-850 AC), el período Talayótico (850-550 AC) y el Postalayótico (550-123 AC), se propone analizar los cambios y pervivencias en la construcción del paisaje, a través de estrategias de visibilidad, percepción y movimiento alrededor de los monumentos arquitectónicos. A través de la perspectiva de la Arqueología del Paisaje y mediante el uso de Sistemas de Información Geográfica (SIG) se propone un análisis de tendencias a largo plazo en la configuración social de un paisaje.

Pour rester compétitives, les entreprises forestières cherchent à contrôler leurs coûts d’approvisionnement. Les abatteuses-façonneuses sont pourvues d’ordinateurs embarqués qui permettent le contrôle et l’automatisation de certaines fonctions. Or, ces technologies ne sont pas couramment utilisées et sont dans le meilleur des cas sous-utilisées. Tandis que l’industrie manifeste un intérêt grandissant pour l’utilisation de ces ordinateurs, peu de travaux de recherche ont porté sur l’apport en productivité et en conformité aux spécifications de façonnage découlant de l’usage de ces systèmes. L’objectif de l’étude était de mesurer les impacts des trois degrés d’automatisation (manuel, semi-automatique et automatique) sur la productivité (m3/hmp) et le taux de conformité des longueurs et des diamètre d’écimage des billes façonnées (%). La collecte de données s’est déroulée dans les secteurs de récolte de Produits forestiers résolu au nord du Lac St-Jean entre les mois de janvier et d’août 2015. Un dispositif en blocs complets a été mis en place pour chacun des cinq opérateurs ayant participé à l’étude. Un seuil de 5 % a été employé pour la réalisation de l’analyse des variances, après la réalisation de contrastes. Un seul cas a présenté un écart significatif de productivité attribuable au changement du degré d’automatisation employé, tandis qu’aucune différence significative n’a été détectée pour la conformité des diamètres d’écimage; des tendances ont toutefois été constatées. Les conformités de longueur obtenues par deux opérateurs ont présenté des écarts significatifs. Ceux-ci opérant sur deux équipements distincts, cela laisse entrevoir l’impact que peut aussi avoir l’opérateur sur le taux de conformité des longueurs.

Deposition of indium tin oxide (ITO) among various transparent conductive materials on flexible organic substrates has been intensively investigated among academics and industrials for a whole new array of imaginative optoelectronic products. One critical challenge coming with the organic materials is their poor thermal endurances, considering that the process currently used to produce industry-standard ITO usually involves relatively high substrate temperature in excess of 200°C and post-annealing. A lower processing temperature is thus demanded, among other desires of high deposition rate, large substrate area, good uniformity, and high quality of the deposited materials. For this purpose, we developed an RF-assisted closed-field dual magnetron sputtering system. The “prototype” system consists of a 3-inch unbalanced dual magnetron operated at a closed-field configuration. An RF coil was fabricated and placed between the two magnetron cathodes to initiate a secondary plasma. The concept is to increase the ionization faction with the RF enhancement and utilize the ion energy instead of thermal energy to facilitate the ITO film growth. The closed-field unbalanced magnetrons create a plasma in the intervening region rather than confine it near the target, thus achieving a large-area processing capability. An RF-compensated Langmuir probe was used to characterize and compare the plasmas in mirrored balanced and closed-field unbalanced magnetron configurations. The spatial distributions of the electron density ne and electron temperature Te were measured. The density profiles reflect the shapes of the plasma. Rather than intensively concentrated to the targets/cathodes in the balanced magnetrons, the plasma is more dispersive in the closed-field mode with a twice higher electron density in the substrate region. The RF assistance significantly enhances ne by one or two orders of magnitude higher. The effect of various other parameters, such as pressure, on the plasma was also studied. The ionization fractions of the sputtered atoms were measured using a gridded energy analyzer (GEA) combined with a quartz crystal microbalance (QCM). The presence of the RF plasma effectively increases the ITO ionization fraction to around 80% in both the balanced and closed-field unbalanced configurations. The ionization fraction also varies with pressure, maximizing at 5-10 mTorr. The study of the ionization not only facilitates understanding the plasma behaviors in the RF-assisted magnetron sputtering, but also provides a criterion for optimizing the film deposition process. ITO films were deposited on both glass and plastic (PET) substrates in the 3-inch RF-assisted closed-field magnetrons. The electrical resistivity and optical transmission transparency of the ITO films were measured. Appropriate RF assistance was shown to dramatically reduce the electrical resistivity. An ITO film with a resistivity of 1.2×10-3 Ω-cm and a visible light transmittance of 91% was obtained with a 225 W RF enhancement, while the substrate temperature was monitored as below 110°C. X-ray photoelectron spectroscopy (XPS) was employed to confirm the ITO film stoichiometry. The surface morphology of the ITO films and its effect on the film properties were studied using atomic force microscopy (AFM). The prototype of RF-assisted closed-field magnetron was further extended to a larger rectangular shaped dual magnetron in a flat panel display manufacturing system. Similar improvement of the ITO film conductivities by the auxiliary RF was observed on the large-area PET substrates. Meanwhile, significant deposition rates of 25-42 nm/min were achieved.

ABSTRACT: Purpose: This study explores how the decision to disclose Childhood Sexual Abuse (CSA) to the legal setting for adult victims is perceived by key informants, specifically factors that are believed to facilitate or prevent legal disclosure from occurring. Background: Prevalence rates of CSA are high (Pereda, Guilera, Forns & Gomez-Benito, 2009) and the negative consequences caused by the abuse acknowledged (Filipas & Ullman, 2006). Disclosure of this crime is understood to be complex and delayed disclosure recognised (Arata, 1998) but little is known about disclosure to the legal system. Rates of legal disclosure of CSA remain low and the attrition rates high (London, Bruck, Ceci & Shuman, 2005), but investigation and understanding of the contributory factors is rare. Disclosure of CSA to the legal system enables prosecution of the abuser and protection of the victim and others. Method: 10 “key informants” consisting of specialised clinicians working with adult victims of CSA were interviewed. Each informant completed an indepth interview exploring their beliefs about factors that facilitated or prevented adult victims of CSA from disclosing their experience to the legal system. Interviews were transcribed and the qualitative data subjected to Thematic Analysis. Conclusions: Two super-ordinate themes (Legal Disclosures Are Rare: “Why would they do that?” and The Anomalies: Acknowledging that this is a crime) and four sub-ordinate themes emerged from the analysis and an analytical narrative constructed. Themes emphasised the rarity of legal disclosure and the significant number of barriers adult victims of CSA perceive. Implications for clinical practice and future research are outlined.

El hostigamiento psicológico en el trabajo (mobbing) es un problema de considerable magnitud para el personal de enfermería a nivel mundial. Aunque el maltrato psicológico laboral esté basado en comportamientos subjetivos, el elevado número de personas que lo testifica plantea, como mínimo, una mayor reflexión sobre este tema. El objetivo de este estudio es analizar la problemática del mobbing desde el punto de vista exclusivo de los testigos y conocer las repercusiones psicológicas del fenómeno sobre los mismos. Se realizó un estudio descriptivo transversal, usando cuestionarios autoadministrados. La muestra está compuesta de 204 profesionales de enfermería, de los cuales el 28.4% reportaron haber testificado conductas hostiles hacia sus compañeros de trabajo. Las conductas más observadas fueron el desprestigio profesional, la humillación, el rechazo profesional, el ninguneo y el aislamiento profesional. Los resultados demostraron que los testigos de hostigamiento psicológico, aunque no se percibían víctimas de ello, presentaban significativamente más síntomas de estrés que los no testigos, así como un mayor deseo de abandonar la profesión y una mayor percepción de que la enfermería es una profesión poco valorada. Los resultados indican que el mobbing en enfermería es un comportamiento objetivable y que su impacto repercute negativamente en los observadores del mismo, convirtiéndolos en víctimas secundarias del fenómeno.
