Abstract
OBJECTIVE. Our objective was to perform initial psychometric analysis of the Multiple Errands Test Home Version (MET–Home), which was designed to assess the influence of poststroke executive dysfunction on in-home task performance.
METHOD. We examined the reliability and validity of the MET–Home in adults with stroke (n = 23) and individually matched control participants (n = 23). All participants completed a series of assessments during a single in-home visit.
RESULTS. Notable differences in MET-Home subscores were discovered between participants with stroke and control participants. Participants with stroke omitted more tasks, broke more rules, passed by tasks more often, and were less efficient than matched control participants. The MET–Home demonstrated evidence of adequate internal consistency, excellent interrater reliability, and significant moderate associations with several tests.
CONCLUSION. This preliminary study suggests that the MET–Home differentiates between adults with stroke and matched control participants. The MET–Home provides evidence of initial reliability and validity among adults with stroke.

Published: May 2019

Introducción: Las condiciones climáticas en la Faja Volcánica Transmexicana durante el Holoceno medio fueron diferentes de las actuales, lo que pudo tener un efecto en las áreas de distribución histórica del oyamel (Abies religiosa [Kunth] Schltdl. & Cham.).
Objetivo: Determinar si los requerimientos ambientales que delimitan la distribución actual del oyamel en la Faja Volcánica Transmexicana han cambiado desde hace 6 000 años.
Materiales y métodos: Los registros de A. religiosa se obtuvieron de la plataforma Niche Toolbox. Se descargaron las variables WorldClim versión 2.0 para los periodos actual (1970-2000) y Holoceno medio (modelos CNRMCM5 y MIROC_ESM). Los modelos de distribución se generaron en MaxEnt utilizando 75 % de los datos para entrenamiento y 25 % para validación. Las variables más importantes de cada periodo se determinaron con la prueba de Jackknife.
Resultados y discusión: Las superficies estimadas de oyamel fueron similares en ambos periodos. Aproximadamente, 86.5 % de la distribución del oyamel se encuentra en áreas naturales protegidas de la zona. Las variables ambientales limitantes de la distribución son la altitud, precipitación anual, precipitación de verano, temperatura media anual y oscilación diurna en temperatura. El Nevado de Toluca y la Ciudad de México presentaron superficies mayores de oyamel (+2 658.4 ha y +20 129.7 ha, respectivamente) durante el Holoceno medio. La precipitación anual era 80 a 224 mm mayor que la actual y la temperatura era 1 °C más fría.
Conclusión: Las variables ambientales de mayor importancia para la distribución del oyamel son similares a las reportadas en la literatura, lo que indica similitud entre el nicho ecológico actual e histórico de A. religiosa.

Introducción: La precipitación es un factor importante en el aporte de nutrientes a los ecosistemas. En algunos casos, mediante la lluvia pueden agregarse elementos que por las condiciones del área no están disponibles.
Objetivo: Comparar el aporte nutrimental en la precipitación incidente (Pi) y en el agua de lluvia que llega al suelo por precipitación directa (Pd) y escurrimiento fustal (Ef) de especies de matorral.
Materiales y métodos: Se evaluaron 41 eventos de lluvia en el noreste de México en el periodo septiembre 2016-septiembre 2017. Se registraron los volúmenes de precipitación y se analizó su composición química: pH, conductividad eléctrica y aporte de macro (Ca, Mg, K) y micronutrientes (Fe, Mn, Zn y Cu).
Resultados y discusión: La Pi acumuló 508.97 mm. La Pd es la que deposita mayor cantidad de nutrientes al suelo. El aporte neto (Pd+Ef) indicó que el Fe fue el micronutriente más depositado con 2 938.29 g·ha-1·año-1, de los cuales Casimiroa greggii (S. Watson) F. Chiang aportó 31.59 %. El macronutriente con mayor presencia fue el Ca con 319.31 kg·ha-1·año-1, siendo Acacia farnesiana (L.) Willd. la que logró mayor flujo del mineral (22.66 %). El pH y conductividad eléctrica fueron similares (Kruskal-Wallis, P > 0.05) en los tres tipos de precipitación.
Conclusión: La química de la precipitación se modifica después de pasar el dosel de cada especie, ya sea para enriquecer o remover las concentraciones de nutrientes, jugando un papel importante en los ciclos biogeoquímicos del ecosistema.

ABSTRACT
A bio-based process oil for rubber compounds is one of the compounding ingredients to be used toward an eco-friendly and more sustainable rubber technology. This work investigates epoxidized palm oil (EPO) as an alternative for petroleum-based process oil in silica-reinforced natural rubber (NR) tire tread compounds. The effect of different incorporating steps of EPO on the properties of the rubber compounds is first studied, taking into account that the polar functional groups in the oil molecules may interact with the silanol groups on the silica surface. The properties of silica-reinforced NR compounds with EPO oil are compared with that of reference mixes with treated distillate aromatic extract (TDAE) and without oil. The compounds with EPO show a lower viscosity, filler–filler interaction, and flocculation rate constant but higher cure reaction rate constants compared with the compound with TDAE. The results indicate that the epoxide groups in EPO interact with the silanol groups on the silica surface, promoting a greater shielding effect on the polar surface and thus better silica dispersion and less interference with the vulcanization reaction. The different incorporating steps of EPO show no significant effect on the viscosity, filler–filler interaction, or flocculation rate constant but clearly affect the extent of crosslinking, as indicated by the cure torque difference. The presence of EPO in an early stage of the mixing together with the first half addition of silica and silane results in the lowest cure torque difference, modulus, and tensile strength (i.e., the highest tan δ at 60 °C), which indicates a possible obstruction for the interaction between the silanol groups and silane coupling agent by the EPO molecules. Comparing EPO with different epoxide contents in the range of 1–3 mol%, the increase in epoxide content gives similar Payne effects but enhances the cure reaction, resulting in improved tensile properties and tan δ at 60 °C. The results clearly prove that EPO can be used as a TDAE alternative.
Predicting Stock Return of UAE Listed Companies Using Financial Ratios
Authors: Banerjee Arindam 
Published: May 2019

Over the past few decades, numerous research across the globe has been conducted to examine the impact of firm performance on its stock return. The findings of these studies have been varied. In spite of the long standing research in this area, several attempt towards exploring this relationship has led to limited success owing largely to the existence of volatility across different stock markets. The variance in the volatility in these markets make it extremely difficult to obtain a uniform measure. A volatile stock market makes it difficult for the accounting and financial variables to accurately predict the stock returns (Feris & Erin, 2018). The primary aim of this paper is aimed to investigate whether financial ratios can be used as a predictor of stock returns in the context of United Arab Emirates (UAE). The sample of the study includes thirty companies from the Dubai Financial Market (DFM) and Abu Dhabi stock exchange (ADX). Data is collected for the period of 2017. This research comprises of five independent variables namely, Earning Per Share ratio (EPS), Price Earning ratio (PE), Return on Equity ratio (ROE), Dividend Yield ratio (DY) and Debt Equity ratio (DE) and stock return is taken as the dependent variable. The study examines which among the given ratios can better predict stock returns both in the short run and the long run. The analysis is based on the regression analysis and correlation matrix. The results of correlation test revealed less multicollinearity between the variables and the regression results showed that Dividend Yield and the Return on Equity are statistically significant to predict the stock returns. However, Earning Per Share, Price Earning and Debt Equity could not predict the stock returns and thus can be safely considered as statistically insignificant. The t-stats test and p-value analysis were key indicators for arriving at the conclusion. The study can significantly benefit investors who can examine closely the dividend yield and return on equity while selecting an optimal portfolio.
Quality of Life in Breast Cancer Patients: The Moderator Role of Family Stress

Published: May 2019

In breast cancer patients, quality of life has been associated with treatment response and overall survival. One hundred women undergoing chemotherapy treatment for breast cancer completed questionnaires including demographic and clinical information, the EORTC-Quality of Life Questionnaire, Hospital Anxiety and Depression Scales, Body Image Scale, Index of Family Relations and the Life Orientation Test. The results showed that higher optimism and better body image were associated with improved quality of life. Distress significantly predicted physical and emotional quality of life, but recurrence only predicted physical quality of life. Family stress was a moderator in the relationship between psychological distress and emotional quality of life, showing the need to screen and intervene on family stress in patients with breast cancer. The results may help in designing interventions for women with breast cancer in order to promote quality of life.

This study addressed the development and evaluation of the Smile Program whose main objective was the prevention of depression and the promotion of well-being in adolescents. The program is based on interventions that have been shown to be efficacious (a cognitive-behavioral approach). Participants were 89 adolescents (mean age = 13.88 years; SD = 0.95) recruited from a sample of 1212 students from seven schools. Results showed a significant reduction in self-reported depressive symptoms in the intervention group (n= 51) as compared to youth in the control group (n= 38). Based on parents’ report (n=56), youth in the intervention group had significantly better self-esteem at post-test as compared to youth in the control group. At four months post intervention, youth in the intervention group had higher psychological well-being than those in the control group; at the 8-month follow-up, youth in the intervention condition reported better family self-concept.

La atención médica y psicológica de pacientes con patología dual es realizada por servicios de salud mental, adicciones, o coordinada. No obstante, es elección de los pacientes acudir a uno u otro servicio. Este trabajo tiene como objetivo analizar las semejanzas y diferencias de pacientes con patología dual que acuden a estos centros. El estudio se ha realizado con170 pacientes diagnosticados de patología dual atendidos en el Servicio Provincial de Drogodependencias de Huelva (SPDH) y Unidades de Salud Mental Comunitaria (USMC) de la provincia de Huelva. En el SPDH la prevalencia de pacientes con dependencia a heroína y cocaína es mayor (35.9% vs 2% en USMC y 16.4% en coordinado). En las USMC se observa una mayor prevalencia de pacientes con dependencia a cannabis (41.2% vs 9.4% en el CTA y 16.4% en coordinado). La odds ratio para pacientes con episodios hipomaníacos fue de 2.879 (p<0.05) en el SPDH, y de 0.483 (p<0.05) para episodios maníacos. Hay una mayor prevalencia de pacientes con trastornos psicóticos en las USMC en comparación con el SPDH (66% vs 37.5%). Las diferencias detectadas en los perfiles deben ser consideradas en la planificación asistencial de los centros que atienden a estos pacientes.
Dual patients are usually treated in drug users services, mental health units, or both. However, each patient can choose the service to receive the health care. The aim of this study is to analyze the similarities and differences of the patient profiles that are treated in each one of these centers. The sample consists of 170 patients diagnosed with dual pathology treated at Servicio Provincial de Drogodependencias de Huelva (SPDH) and Unidades de Salud Mental Comunitaria (USMC) in the province of Huelva. In SPDH, higher prevalence of patients with cocaine and heroin dependence profile was observed (35.9% vs 2% in MH and 16.4% in coordinated). In USMC there is higher prevalence of patients with cannabis dependence profile (41.2% vs 9.4% in the DU and 16.4% in the coordinated service). The odds ratio for patients with hypomanic episodes was 2,879 (p <0.05) in SPDH compared to other services. Odds ratio observed for manic episodes was 0.483 (p <0.05) in SPDH. Patients with comorbid psychotic disorders are more prevalent in USMC compared to SPDH services (66% vs 37.5%). The differences observed in the profiles should be considered in the care planning of these centers.

Published: May 2019

La creatividad y las prácticas ligadas a fomentarla en el ámbito universitario constituyen en la actualidad un tema de interés. La creatividad en tanto fenómeno multidimensional requiere ser evaluada en sus distintas facetas, siendo la personalidad una de las que mayor relevancia reviste. Se propone así, adaptar localmente la Escala de Personalidad Creativa (EPC) de Gough para ser aplicada en el ámbito universitario. El instrumento se compone de 30 adjetivos a ser respondidos por los evaluados según se identifiquen o no con cada uno de ellos. Se realizó un análisis factorial exploratorio y de consistencia interna (n = 150) y otro confirmatorio y de validez convergente (n = 150) a partir de dos muestras independientes. El procedimiento exploratorio conservó ocho ítems y una estructura factorial unidimensional con una óptima consistencia interna (alfa ordinal = .853). Este modelo se verificó empíricamente mediante el análisis confirmatorio que arrojó óptimos índices de ajuste y un apropiado índice de consistencia interna. Adicionalmente se obtuvieron adecuadas evidencias de validez convergente del instrumento en relación a otros constructos teóricamente afines. Los resultados se discuten a la luz de la teoría y las limitaciones del diseño, destacando los alcances del estudio y las futuras líneas de investigación.
Creativity and actions aimed at fostering it became a matter of interest in higher education. Since creativity is a multidimensional phenomenon, its diverse dimensions must be assessed. Among them, personality arises as the most relevant one. Therefore, the local adaptation of Gough’s Creative Personality Scale to be used in college students is proposed. This scale is composed of adjectives to be responded according to the examinees’ identification with each one of them. Two independent samples (n= 150 each) were employed to develop an exploratory factor analysis and an internal consistency analysis, on the one hand, and a confirmatory factor analysis and a convergent validity study.
The exploratory procedure retained eight items and a 1-dimension structure with a good internal consistency (ordinal alpha= .853). This model was empirically verified by the confirmatory analysis which showed good fit indices, as well as an adequate internal consistency coefficient. Moreover, adequate convergent validity evidences were obtained. Findings are discussed taking into account the theoretical model and the study weaknesses along with practical and theoretical outcomes. Further research lines are proposed.
Voyage sous « Goyave » : anagrammes et autres clefs d’accès à l’univers romanesque de Yodi Karone
Authors: Tsoualla Blaise 
Published: May 2019

L’emblématique anagramme de « Goyave » recouvre chez Karone la notion de voyage. Avec d’autres techniques de dissimulation, elle participe d’une stratégie de survie dans un contexte hostile aux auteurs camerounais gagnés à l’indignation et à la résistance. De tels motifs cachent alors une façon de se mettre hors d’atteinte, d’exemplifier le vide de la quête existentielle, d’atteindre chaque cible/lecteur sans compromettre la vision progressiste de l’écriture, mais aussi d’assurer le plaisir et la jouissance du texte.
Les gueules cassées ou l’éthique de l’écran crevé : du masque au visage cinématographique
Authors: Chevalier Karine 
Published: May 2019

Cet article analyse comment le cinéma représente les gueules cassées en relation avec les autres médias (actualités, photographie, littérature, peinture, bande dessinée). À partir de la distinction de Levinas entre « la face » et « le visage », l’auteure questionne le recours au camouflage. Les blessures de guerre sont ainsi cachées par une esthétique du masque, telle que la surimpression, qui permet selon une approche éthique ambivalente de révéler le « visage » au-delà de la défiguration.
Inhabiting the Profile: Zach Blas’ Facial Weaponization Suite
Authors: Althoff Sebastian 
Published: May 2019

This article places Zach Blas’ Facial Weaponization Suite (2011–2014) in relation to the notion of algorithmic governmentality in order to reveal a tactic of disidentification. Algorithmic governmentality refers to the implementation of big data surveillance that does not render individuals visible, but rather circumvents them, thereby complicating the possibility of a critical engagement. Such critical engagement, however, can be envisioned through the Facial Weaponization Suite.
Hybrid identification in Nothofagus subgenus using high resolution melting with ITS and trnL approach
Authors: Solano Jaime , Anabalón Leonardo , Encina Francisco , Esse Carlos , Penneckamp Diego 
Published: May 2019

The genus Nothofagus is the main component of southern South American temperate forests. The 40 Nothofagus species, evergreen and deciduous, and some natural hybrids are spread among Central and Southern Chile, Argentina, New Zealand, Australia, New Guinea and New Caledonia. Nothofagus nervosa, Nothofagus obliqua and Nothofagus dombeyi are potentially very important timber producers due to their high wood quality and relative fast growth; however, indiscriminate logging has degraded vast areas the Chilean forest causing a serious state of deterioration of their genetic resource. The South of Chile has a large area covered by secondary forests of Nothofagus dombeyi. These forests have a high diversity of species, large amount of biomass and high silvicultural potential. This work shows a case of hybrid identification in Nothofagus subgenus in different secondary forests of Chile, using high resolution melting. Unknown samples of Nothofagus subgenus are genetically distinguishable with the ITS region of Nothofagus antarctica, Nothofagus nitida and N. obliqua species. It was not possible to distinguish between unknown samples of Andean versus coastal origin. Melting curves with ITS approach of unknown material are genetically similar, positioned between N. dombeyi and N. antarctica and distant from N. nitida. The unknown samples are genetically very close to Nothofagus dombeyi. This suggests the presence of hybrid individuality between species (N. dombeyi × N. antarctica) with the possibility of introgression towards the gene pool of N. antarctica, producing the deciduous foliage that is both present. The trnL locus has no distinction between the N. dombeyi and N. antarctica species, since a similar melting curve is present and equal Tm (80.00 °C). The trnL locus cannot be genetically distinguished from one unknown sample of Nothofagus to another, as highlighted in this study.
Dominance in dogs as rated by owners corresponds to ethologically valid markers of dominance
Authors: Kubinyi Enikő , Wallis Lisa J. 
Published: May 2019

Dominance is well defined in ethology, debated in psychology, and is often unclear among the dog owning public and in the press. However, to date, no study has examined how owners perceive dominance in dogs, and what different behaviours and personality types are used to describe dominant and subordinate individuals. A questionnaire study was launched to investigate the external validity of owner-derived estimates of dominance in dog dyads sharing the same household (N = 1,151). According to the owners, dogs rated as dominant (87%) have priority access to resources (resting place, food, and rewards), undertake certain tasks (defend and lead the group, bark more), display dominance (win fights, lick the other’s mouth less, and mark over the other’s urine), share certain personality traits (smarter, more aggressive and impulsive), and are older than their partner dog (all p < 0.0001). An age-related hypothesis has been suggested to explain dominance in dogs; but we found that dog age did not explain the occurrence of dominance related behaviours over the owners’ estimate of dominance status. Results suggest that owner-derived reports of dominance ranks of dogs living in multi-dog households correspond to ethologically valid behavioural markers of dominance. Size and physical condition were unrelated to the perceived dominance. Surprisingly, in mixed-sex dyads, females were more frequently rated as dominant than males, which might correspond to a higher proportion of neutered females in this subgroup. For future studies that wish to allocate dominance status using owner report, we offer a novel survey.
