A syntactic-semantic analysis of English (non)-dativizable constructions in the production of a set of 2L1 English/Spanish simultaneous bilingual twins

This paper analyzes the syntactico-semantic factors which trigger Dative shift in English dativizable verbs, i.e. those verbs that allow alternation between double object and prepositional complement constructions. It also focuses on non-dativizable verbs that restrict their subcategorization framework to either double object or prepositional complement constructions. This syntactico-semantic relation between dativizable and nondativizable structures is addressed in acquisition by examining the incidence for the two verb types in a set of English/Spanish 2L1 bilingual twins. Our results show that the syntactic and semantic features that dativizable and non-dativizables present go hand in hand with the age of first occurrence and the language development of the participants. Hence, dativizable to-dative double object constructions (DOC) are the utterances produced the earliest at the age of 2, as opposed to dativizable to/for-datives and non-dativizable constructions, which begin to emerge at around the age of 3. Finally, our results also suggest that the high adult input frequency explains the twins' early production of dativizable structures and that, in the same way, the children's low exposure to non-dativizable utterances correlates with the later occurrence in the twins' spontaneous production.peer-reviewe

CULTURAL AND STRUCTURAL BARRIERS OF UTILIZING MENTAL HEALTH SERVICES IN A SCHOOL-BASED SETTING FOR LATINX POPULATIONS

This qualitative research study aimed to reduce mental health service disparities in Latinx communities and helps fill in the gap by addressing cultural and structural barriers to utilizing MHS in a school-based setting for Latinx youth. There is limited research regarding Latinx parents’ perspectives and the reservations they have on utilizing school-based mental health services (MHS) for their children. This study identified six important themes: cultural factors, trust and rapport, reservations, access and awareness, parental involvement and challenges, and school-based resources. Implications for school districts are that they can use these findings to increase early intervention mental behavioral health programs and minimize barriers to mental health services. Latinx students will be able to receive timely support within a familiar and comfortable environment. There should be special considerations to how both culture and structural barriers impact utilization of MHS in a school setting and promote culturally sensitive mental health services to Latinx youth in school settings

La representación de la tecnología en 2001: odisea en el espacio

Hace más de 50 se estrenó una de las películas más importantes de todos los tiempos: 2001: Odisea en el espacio, dirigida por el director Stanley Kubrick. Este film del cine de ciencia ficción relata los inicios de la humanidad donde el hombre lucha por sobrevivir a la naturaleza hasta su llegada al espacio exterior donde logra conquistar las estrellas. El objetivo general de la presente investigación es analizar por medios teóricos y visuales la representación de la tecnología en la película con el propósito de diseñar una colección. Por una parte, en el aspecto teórico se consultaron diversas fuentes como estudios profundos basados en análisis minuciosos de la película por parte de cineastas, críticos y teóricos del cine. Estos estudios responden a un desglose de la puesta en escena del film desde perspectivas artísticas, filosóficas; y por supuesto sociales y culturales. Por otra parte, en el ámbito visual la recopilación de referencias responde principalmente a escenas de la película sobre la representación de la tecnología teniendo en cuenta la información teórica recaudada. Con base en las características del film es conocido por ofrecer una experiencia visual transformadora por lo que es una fuente valiosa de recursos para el proyecto de diseño.More than 50 years ago, one of the greatest films of all time was released: 2001: A Space Odyssey which was directed by Stanley Kubrick. This science fiction film tells the beginning of humanity where man struggles to survive nature until he conquest outer space. The general objective of this research is to analyze by theoretical and visual means the representation of technology in the film with the purpose of designing a fashion collection. On the one hand, on the theoretical side, various sources were consulted, such as in-depth studies based on detailed analysis of the film made by filmmakers, critics, and film theorists. These studies respond to a breakdown of the staging of the film from artistic and philosophical perspectives; and of course, social, and cultural. On the other hand, in the visual field, the visual references respond mainly to scenes from the film on the representation of technology, considering the theoretical information collected. Based on the characteristics of the film, it is known to offer a transformative visual experience, making it a valuable source of resources for the design project.Trabajo de investigació

Determinación de la fuerza de roce con el aire usando nuevas tecnologías

En este trabajo presentamos un experimento de bajo costo para estudiar la caída de los cuerpos cuando los efectos del roce con el aire son significativos. Este experimento permite determinar la cinemática de un cuerpo que cae en el aire y “descubrir” las leyes que rigen el roce de un objeto en un medio fluido y su dependencia con la velocidad del mismo. El dispositivo experimental hace uso de una cámara digital comercial en modo vídeo. Se analiza la caída de filtros de café y globos cargados con diferentes pesos. Nuestro estudio revela que en su caída, estos objetos alcanzan rápidamente una velocidad constante que es proporcional al peso de los mismos. Usando las leyes de Newton podemos inferir que esta fuerza de roce es proporcional al cuadrado de la velocidad

An Intervention Delivered by App Instant Messaging to Increase Acceptability and Use of Effective Contraception Among Young Women in Bolivia: Protocol of a Randomized Controlled Trial.

BACKGROUND: Unintended pregnancy is associated with numerous poorer health outcomes for both women and their children. Fulfilling unmet need for contraception is essential in avoiding unintended pregnancies, yet millions of women in low- and middle-income countries continue to face obstacles in realizing their fertility desires. In Bolivia, family planning progress has improved in recent decades but lags behind other countries in the region. Unmet need for contraception among women aged 15 to 19 years is estimated to be 38%, with the adolescent fertility rate at 70 per 1000 women. Mobile phones are an established and popular mode in which to deliver health behavior support. The London School of Hygiene & Tropical Medicine and the Centro de Investigación, Educación y Servicios in Bolivia have partnered to develop and evaluate a contraceptive behavioral intervention for Bolivian young women delivered by mobile phone. The intervention was developed guided by behavioral science and consists of short instant messages sent through an app over 4 months. OBJECTIVE: The objective of this study is to evaluate the effect of the intervention on young women's use of and attitudes toward the most effective contraceptive methods. METHODS: We will allocate 1310 women aged 16 to 24 years with an unmet need for contraception in a 1:1 ratio to receive the intervention messages or the control messages about trial participation. The messages are sent through the Tú decides app, which contains standard family planning information. Coprimary outcomes are use and acceptability of at least one effective contraceptive method, both measured at 4 months. RESULTS: Recruitment commenced on March 1, 2017 and was completed on July 29, 2017. We estimate that the follow-up period will end in January 2018. CONCLUSIONS: This trial will evaluate the effect of the intervention on young women's use of and attitudes toward the (nonpermanent) effective contraception methods available in Bolivia.

At the southeast fringe of the Bantu expansion: genetic diversity and phylogenetic relationships to other sub-Saharan tribes

Here, we present 12 loci paternal haplotypes (Y-STR profiles) against the backdrop of the Y-SNP marker system of Bantu males from the Maputo Province of Southeast Africa, a region believed to represent the southeastern fringe of the Bantu expansion. Our Maputo Bantu group was analyzed within the context of 27 geographically relevant reference populations in order to ascertain its genetic relationship to other Bantu and non Bantu (Pygmy, Khoisan and Nilotic) sub-equatorial tribes from West and East Africa. This study entails statistical pair wise comparisons and multidimensional scaling based on YSTR Rst distances, network analyses of Bantu (B2a-M150) and Pygmy (B2b-M112) lineages as well as an assessment of Y-SNP distribution patterns. Several notable findings include the following: 1) the Maputo Province Bantu exhibits a relatively close paternal affinity with both east and west Bantu tribes due to high proportion of Bantu Y chromosomal markers, 2) only traces of Khoisan (1.3%) and Pygmy (1.3%) markers persist in the Maputo Province Bantu gene pool, 3) the occurrence of R1a1a-M17/M198, a member of the Eurasian R1a-M420 branch in the population of the Maputo Province, may represent back migration events and/or recent admixture events, 4) the shared presence of E1b1b1-M35 in all Tanzanian tribes examined, including Bantu and non-Bantu groups, in conjunction with its nearly complete absence in the West African populations indicate that, in addition to a shared linguistic, cultural and genetic heritage, geography (e.g., east vs. west) may have impacted the paternal landscape of sub-Saharan Africa, 5) the admixture and assimilation processes of Bantu elements were both highly complex and region-specific

Evaluación del proceso y producto de una propuesta de audiodescripción de tres obras de la exhibición permanente de arte moderno del museo de arte de Lima

This study evaluates the process and product of our proposal of audio description for three pieces of the permanent modern art exhibit from the Museo de Arte de Lima taking as reference the ISO/IEC TS 20071-21:2015 quality standard. We assume that complying with this standard will assure the quality of the audio description. This study stands on the project evaluation framework with emphasis on intersubjectivity. The results conclude that the ISO lacks of specific guidelines to audio describe works of art, in contrast to the ones given for other audiovisual products. Nevertheless, it still remains as an excellent departing point to create audio descriptions. Thus, due to the lack of an exclusive focus in museum audio description, we decided to evaluate these guidelines according to the insights of authors such as Snyder (2005), Gallego and Nuñez (2014) and Giansante (2003), managing to make them more case specific.La presente investigación evalúa el proceso y producto de nuestra propuesta de audiodescripción de tres obras de la exhibición permanente de arte moderno del Museo de Arte de Lima teniendo como referencia la norma de calidad ISO/IEC TS 20071-21:2015, bajo supuesto de que cumplir con dicha norma garantizará la calidad de la audiodescripción. Este estudio está basado en el método de evaluación de proyectos, con énfasis en la intersubjetividad. Los resultados concluyen que la norma ISO carece de pautas específicas para audiodescribir obras de arte, pero sí profundiza en la audiodescripción de otros productos visuales o audiovisuales, por lo que es un excelente punto de partida para realizar audiodescripciones. Así, frente a esta carencia de enfoque hacia la audiodescripción museística, optamos por complementar y evaluar dichas pautas desde los aportes de autores como Snyder (2005), Soler Gallego y Chica Núñez (2014) y Giansante (2003), logrando alcanzar más especificidad en cada caso.

Enteroparasitas em alfaces (Lactuca sativa) comercializadas na cidade de Guarapuava (PR)Enteroparasites on commercial lettuce (Lactuca sativa) in Guarapuava City, Paraná State

O consumo de hortaliças cruas constitui importante meio de transmissão de enteroparasitoses. O objetivo deste trabalho foi avaliar a contaminação parasitária em alfaces (Lactuca sativa) comercializadas na cidade de Guarapuava (PR). No período de julho/2005 a junho/2006, 52 supermercados foram visitados, com colheita de um pé de alface. A análise parasitológica foi realizada após duas lavagens, filtragem em gaze e sedimentação. O sedimento, corado pelo lugol, foi analisado microscopicamente por exame direto e após centrífugo-flutuação em sulfato de zinco. Das 52 amostras de alface avaliadas, 18 (34,6%) apresentaram uma ou mais estruturas parasitárias como cistos de Giardia spp. (7,7%), de Entamoeba spp. (11,5%) e de Balantidium coli (3,8%), oocistos de coccídios (7,7%) e ovos de Capillaria spp. (3,8%). Esse alto número de amostras contaminadas aponta deficiências na cadeia produtiva dessas hortaliças, indicando a necessidade de adequada higienização antes de seu consumo.Palavras-chave: alface; enteroparasitoses; helmintos; protozoários. AbstractThe ingestion of raw vegetables is an important mode of enteroparasites transmission. The aim of this study was to evaluate the parasitological contamination of lettuce (Lactuca sativa) commercialized in Guarapuava City, Parana State. Fifty-two samples of lettuce were collected from supermarkets during the period of July 2005 and June 2006. Parasitological analysis was realized by the sedimentation technique. Lugol-stained sediments were microscopically analyzed by direct exam and after centrifugation-fluctuation in zinc sulfate. A total of 18 out of 52 lettuce samples analyzed (34.6%) were positive for one or more parasitic structures. The parasites found in the analysis were Giardia spp. (7.7%), Entamoeba spp. (11.5%), Balantidium coli (3.8%), coccidian oocysts (7.7%) and Capillaria spp. eggs (3.8%). Such high occurrence of contaminated samples revealed deficiencies in the chain of lettuce cultivation, which suggests a need for improvement in the current hygienic conditions before consumption.Key words: lettuce; enteroparasites; helminthes; protozoas
