Aspectos teóricos y de adquisición de la distribución del modo subjuntivo en español

Du débat sur la distribution du subjonctif à savoir s’il est possible ou non d’arriver à une explication uniforme de la distribution modale, nous sommes parties de l’idée que la distribution du subjonctif en espagnol s’apparente à la distribution des termes de polarité négative (TPN), c’est-à-dire qu’elle se produit dans des contextes monotoniques décroissants induits par les prédicats opérateurs affectifs, lesquels comprennent autant les prédicats qui régissent le subjonctif polaire que les prédicats qui régissent le subjonctif intensionnel (Potvin, 2004a). À partir de là, nous avons développé une composante théorique et une autre empirique pour montrer que notre explication s’applique non seulement à la distribution modale dans les propositions subordonnées complétives, relatives et adverbiales ainsi qu’aux phrases simples, sinon qu’elle vise à éclaircir l’acquisition de la distribution modale de la part des apprenant.e.s francophones de l’espagnol langue seconde et étrangère. Par conséquent, nous nous positionnons face aux diverses approches de l’acquisition des langues secondes en plus de présenter les traits qui définissent la distribution modale selon les types de phrases en prêtant une attention spéciale aux propositions subordonnées complétives. Tout cela nous mène à traiter deux phénomènes clés de la distribution du subjonctif en espagnol et son acquisition, la polarité et la monotonicité, pour déterminer le rôle que joue le concept de monotonicité dans la distribution du subjonctif d’une part et son rôle dans l’acquisition du subjonctif en espagnol langue seconde et étrangère d’autre part.

Commande optimale d'un satellite à propulsion électrique utilisant les perturbations pour l'élimination des débris orbitaux en basse altitude

Depuis le lancement du premier satellite Spoutnik 1 en 1957, l’environnement spatial est de plus en plus utilisé et le nombre de débris orbitaux se multiplie naturellement, soit par des explosions, des collisions ou tout simplement par les opérations normales des satellites. Au-delà d'un certain seuil, la densité des débris orbitaux risque de créer une réaction en chaîne incontrôlée : l’effet Kessler. L’élimination des débris orbitaux en basse altitude permettrait de limiter cette réaction et ainsi de préserver l’environnement spatial afin de pouvoir l’utiliser de façon sécuritaire. L’élimination des débris orbitaux est une opération complexe et coûteuse. Elle consiste à déplacer des objets spatiaux inactifs vers une orbite basse pour mener à leur désintégration dans la basse atmosphère terrestre. En utilisant les perturbations orbitales, il est possible de réduire le coût du carburant requis pour effectuer les manœuvres orbitales nécessaires à l’élimination de ces débris. L'objectif principal de cette étude consiste à développer une procédure et une stratégie de commande autonome afin de modifier l'orbite des satellites non opérationnels (débris) pour mener à leur désintégration naturelle tout en optimisant les facteurs carburant et temps. Pour ce faire, un modèle d’atmosphère basé sur le modèle de Jacchia (1977) est développé. Un modèle de la dynamique du satellite inclut aussi les perturbations principales, soit : traînée atmosphérique, non sphéricité et distribution non uniforme de la masse de la Terre. Ces modèles ainsi qu'un algorithme de commande optimale pour un propulseur électrique sont développés et le tout est validé par simulations numériques sur Matlab/Simulink. Au terme de cette étude, les conditions optimales dans lesquelles il faut laisser un débris afin qu'il se désintègre dans la basse atmosphère de la Terre en quelques semaines seront données (type d'orbite : altitude, inclinaison, etc.) ainsi que le coût en carburant pour une telle mission. Cette étude permettra de prouver qu'il est possible de réaliser des missions d'élimination des débris orbitaux tout en réduisant les coûts associés aux manœuvres orbitales par l'utilisation des perturbations naturelles de l'environnement.

Desenvolvimento de solenóides para eletroválvulas hidráulicas

Os solenóides para eletroválvulas, em conjunto com outros produtos e equipamentos, permitem a automação dos sistemas de distribuição de águas não potáveis, como, por exemplo, em sistemas de rega. Deste modo é possível controlar diversos parâmetros, como o caudal e a pressão da água que passa na válvula, podendo estes ser fiscalizados à distância. Neste trabalho, foram desenvolvidos solenóides para acoplar a válvulas que se destinam à rega agrícola, comercializadas pela empresa JPrior, Fábrica de Plásticos, Lda. Para o efeito, foram definidos vários processos necessários para a criação de uma linha piloto de pré industrialização destes dispositivos. Etapas como a conceção do dispositivo, prototipagem, testes de temperatura, consumo de corrente, estabilidade eletromecânica e testes de desempenho associados a diferentes valores de pressão e de caudal de funcionamento, foram essenciais para este desenvolvimento, assim como, análises estruturais e morfológicas do material que constitui o núcleo dos solenóides. Além disso, procurou-se responder às necessidades do mercado numa perspetiva mais completa do que a existente. Para isso, foram produzidos dois tipos de solenóides de 24 V AC, com pressões máximas de funcionamento de 4 bar e de 12 bar.

Prevalence of celiac disease among first degree relatives of Brazilian celiac patients

Background - Several studies have shown that celiac disease, an autoimmune disorder that occurs in genetically susceptible individuals, is highly prevalent among relatives of celiac patients. Aim - To determine the prevalence of celiac disease in a group of first degree relatives of Brazilian celiac patients. Methods - First degree relatives of celiac patients attending the Brasilia University Hospital Pediatric Gastroenterology Outpatient Clinic or the Celiac Disease Investigation Center, Brasília, DF, Brazil, between March 2001 and November 2004 were invited to undergo serological screening for celiac disease applying the IgA anti-endomysium antibody test (IgA-EMA). All positive IgA-EMA sera underwent a second screening using the IgA anti-tissue transglutaminase antibodies test. Duodenal or small intestinal biopsies were performed in all subjects positive to serological testing. Biopsy samples were classified as type (O) normal, (I) infiltrative, (II) infiltrative hyperplastic, (III) flat destructive, and (IV) atrophic hypoplastic. The final diagnosis was ascertained in subjects showing positive serological tests and a grade I to III small intestinal lesion. Results - Nine new cases of celiac disease were found among the 188 first degree relatives tested (4.8%). Conclusion - The present study confirms the high prevalence of celiac disease among first degree celiac patients’ relatives and reinforces the need of extensive diagnostic screening in this specific group.

‘Failure to maintain’: care rationing and the clinical and financial burden of nurse sensitive hospital-acquired complications in complex older patients

Background: The ageing population, with concomitant increase in chronic conditions, is increasing the presence of older people with complex needs in hospital. People with dementia are one of these complex populations and are particularly vulnerable to complications in hospital. Registered nurses can offer simultaneous assessment and intervention to prevent or mitigate hospital-acquired complications through their skilled brokerage between patient needs and hospital functions. A range of patient outcome measures that are sensitive to nursing care has been tested in nursing work environments across the world. However, none of these measures have focused on hospitalised older patients. Method: This thesis explores nursing-sensitive complications for older patients with and without dementia using an internationally recognised, risk-adjusted patient outcome approach. Specifically explored are: the differences between rates of complications; the costs of complications; and cost comparisons of patient complexity. A retrospective cohort study of an Australian state’s 2006–07 public hospital discharge data was utilised to identify patient episodes for people over age 50 (N=222,440) where dementia was identified as a primary or secondary diagnosis (N=44,422). Extra costs for patient episodes were estimated based on length of stay (LOS) above the average for each patient’s Diagnosis Related Group (DRG) (N=157,178) and were modelled using linear regression analysis to establish the strongest patient complexity predictors of cost. Results: Hospitalised patients with a primary or secondary diagnosis of dementia had higher rates of complications than did their same-age peers. The highest rates and relative risk for people with dementia were found in four key complications: urinary tract infections; pressure injuries; pneumonia, and delirium. While 21.9% of dementia patients (9,751/44,488, p<0.0001) suffered a complication, only 8.8% of non-dementia patients did so (33,501/381,788, p<0.0001), giving dementia patients a 2.5 relative risk of acquiring a complication (p<0.0001). These four key complications in patients over 50 both with and without dementia were associated with an eightfold increase in length of stay (813%, or 3.6 days/0.4 days) and double the increased estimated mean episode cost (199%, or A$16,403/ A$8,240). These four complications were associated with 24.7% of the estimated cost of additional days spent in hospital in 2006–07 in NSW (A$226million/A$914million). Dementia patients accounted for 22.0% of these costs (A$49million/A$226million) even though they were only 10.4% of the population (44,488/426,276 episodes). Hospital-acquired complications, particularly for people with a comorbidity of dementia, cost more than other kinds of inpatient complexity but admission severity was a better predictor of excess cost. Discussion: Four key complications occur more often in older patients with dementia and the high rate of these complications makes them expensive. These complications are potentially preventable. However, the care that can prevent them (such as mobility, hydration, nutrition and communication) is known to be rationed or left unfinished by nurses. Older hospitalised people who have complex needs, such as those with dementia, are more likely to experience care rationing as their care tends to take longer, be less predictable and less curative in nature. This thesis offers the theoretical proposition that evidence-based nursing practices are rationed for complex older patients and that this rationed care contributes to functional and cognitive decline during hospitalisation. This, in turn, contributes to the high rates of complications observed. Thus four key complications can be seen as a ‘Failure to Maintain’ complex older people in hospital. ‘Failure to Maintain’ is the inadequate delivery of essential functional and cognitive care for a complex older person in hospital resulting in a complication, and is recommended as a useful indicator for hospital quality. Conclusions: When examining extra length of stay in hospital, complications and comorbid dementia are costly. Complications are potentially preventable, and dementia care in hospitals can be improved. Hospitals and governments looking to decrease costs can engage in risk-reduction strategies for common nurse sensitive complications such as healthy nursing work environments that minimise nurses’ rationing of functional and cognitive care. The conceptualisation of complex older patients as ‘business as usual’ rather than a ‘burden’ is likely necessary for sustainable health care services of the future. The use of the ‘Failure to Maintain’ indicators at institution and state levels may aid in embedding this approach for complex older patients into health organisations. Ongoing investigation is warranted into the relationships between the largest health services expense (hospitals), the largest hospital population (complex older patients), and the largest hospital expense (nurses). The ‘Failure to Maintain’ quality indicator makes a useful and substantive contribution to further clinical, administrative and research developments.

Immigration experience of Latin American working women in Alicante, Spain: an ethnographic study

Objective: to describe the experience of Latin American working women regarding immigration, taking into account the expectations and conditions in which this process takes place. Method: ethnographic qualitative study. Data collection was performed by means of semi-structured interviews with 24 Latin American immigrant women in Spain. The information collected was triangulated through two focal groups. Results: the expectations of migrant women focus on improving family living conditions. Social support is essential for their settling and to perform daily life activities. They declare they have adapted to the settlement country, although they live with stress. They perceive they have greater sexual freedom and power with their partners but keep greater responsibility in childcare, combining that with the role of working woman. Conclusions: migrant women play a key role in the survival of households, they build and create new meanings about being a woman, their understanding of life, their social and couple relationships. Such importance is shaped by their expectations and the conditions in which the migration process takes place, as well as their work integration.

Evaluation of the quality of the teaching-learning process in undergraduate courses in Nursing

Objective: to identify aspects of improvement of the quality of the teaching-learning process through the analysis of tools that evaluated the acquisition of skills by undergraduate students of Nursing. Method: prospective longitudinal study conducted in a population of 60 second-year Nursing students based on registration data, from which quality indicators that evaluate the acquisition of skills were obtained, with descriptive and inferential analysis. Results: nine items were identified and nine learning activities included in the assessment tools that did not reach the established quality indicators (p<0.05). There are statistically significant differences depending on the hospital and clinical practices unit (p<0.05). Conclusion: the analysis of the evaluation tools used in the article "Nursing Care in Welfare Processes" of the analyzed university undergraduate course enabled the detection of the areas for improvement in the teaching-learning process. The challenge of education in nursing is to reach the best clinical research and educational results, in order to provide improvements to the quality of education and health care.

Comparação da análise de diferentes perfis de poços pelo método DFA

The study of complex systems has become a prestigious area of science, although relatively young . Its importance was demonstrated by the diversity of applications that several studies have already provided to various fields such as biology , economics and Climatology . In physics , the approach of complex systems is creating paradigms that influence markedly the new methods , bringing to Statistical Physics problems macroscopic level no longer restricted to classical studies such as those of thermodynamics . The present work aims to make a comparison and verification of statistical data on clusters of profiles Sonic ( DT ) , Gamma Ray ( GR ) , induction ( ILD ) , neutron ( NPHI ) and density ( RHOB ) to be physical measured quantities during exploratory drilling of fundamental importance to locate , identify and characterize oil reservoirs . Software were used : Statistica , Matlab R2006a , Origin 6.1 and Fortran for comparison and verification of the data profiles of oil wells ceded the field Namorado School by ANP ( National Petroleum Agency ) . It was possible to demonstrate the importance of the DFA method and that it proved quite satisfactory in that work, coming to the conclusion that the data H ( Hurst exponent ) produce spatial data with greater congestion . Therefore , we find that it is possible to find spatial pattern using the Hurst coefficient . The profiles of 56 wells have confirmed the existence of spatial patterns of Hurst exponents , ie parameter B. The profile does not directly assessed catalogs verification of geological lithology , but reveals a non-random spatial distribution

Nurses', midwives' and key stakeholders' experiences and perceptions on requirements to demonstrate the maintenance of professional competence.

Aim: To present the qualitative findings from a study on the development of scheme(s) to give evidence of maintenance of professional competence for nurses and midwives. Background: Key issues in maintenance of professional competence include notions of self- assessment, verification of engagement and practice hours, provision of an evidential record, the role of the employer and articulation of possible consequences for non-adherence with the requirements. Schemes to demonstrate the maintenance of professional competence have application to nurses, midwives and regulatory bodies and healthcare employers worldwide. Design: A mixed methods approach was used. This included an online survey of nurses and midwives and focus groups with nurses and midwives and other key stakeholders. The qualitative data are reported in this study. Methods: Focus groups were conducted among a purposive sample of nurses, midwives and key stakeholders from January–May 2015. A total of 13 focus groups with 91 participants contributed to the study. Findings: Four major themes were identified: Definitions and Characteristics of Competence; Continuing Professional Development and Demonstrating Competence; Assessment of Competence; The Nursing and Midwifery Board of Ireland and employers as regulators and enablers of maintaining professional competence. Conclusion: Competence incorporates knowledge, skills, attitudes, professionalism, application of evidence and translating learning into practice. It is specific to the nurse's/midwife's role, organizational needs, patient's needs and the individual nurse's/midwife's learning needs. Competencies develop over time and change as nurses and midwives work in different practice areas. Thus, role-specific competence is linked to recent engagement in practice.
