Relaci?n de la capacidad funcional y la calidad de vida relacionada a la salud, bajo la percepci?n de ejercicio del adulto mayor institucionalizado

El inter?s de este estudio fue conocer c?mo los componentes de la capacidad funcional (resistencia a?robica y fuerza), a partir de la percepci?n de ejercicio que tienen los adultos mayores institucionalizados, se relacionan con su calidad de vida, mediante un dise?o de investigaci?n mixto de corte transversal. Se cont? con una poblaci?n de 55 adultos mayores y ancianos pertenecientes a dos instituciones geri?tricas de la ciudad de Cali, de los cuales a partir de los criterios de inclusi?n se tom? una muestra de 22 participantes, quienes conocieron las caracter?sticas del estudio y aceptaron su participaci?n. Se realizaron mediciones antropom?tricas y se evalu? la capacidad funcional por medio de los test de fuerza prensil (FP) y caminata por seis minutos (CMNT6M). En los resultados presentados, se dividi? la muestra por grupos etarios (adultos mayores y ancianos), la calidad de vida fue determinada mediante el cuestionario SF-12v2 validado para Colombia. Mediante una entrevista semi-estructurada, se identific? quienes realizaban ejercicio o no de acuerdo a la percepci?n de los sujetos. Los resultados de los dominios de Calidad de Vida Relacionada a la Salud (CVRS) encontrados no superaron en promedio los 50 puntos, lo que denota una baja percepci?n de la Calidad de Vida (CV) por los participantes. La relaci?n de los componentes de la capacidad funcional y CVRS, basado en la percepci?n de ejercicio, present? una mejor respuesta en aquellos que no participaron de un programa de ejercicios.

A tentative argument for regional quality targets in assimilating schwa

Amerikanenglannin redusoitunut švaa-vokaali tuotetaan puheessa laadultaan huomattavan monimuotoisena. Kirjallisuudessa ei kuitenkaan vallitse selkeää käsitystä siitä, mitkä tekijät ehdollistavat tätä švaan laatuvaihtelua, ja etenkin sen mahdollinen sosiaalinen ulottuvuus on jäänyt aiemmissa tutkimuksissa varsin vähälle huomiolle. Tässä tutkielmassa pyritäänkin selvittämään, millainen vaikutus puhujan alueellisella murteella on hänen tuottamansa švaan akustiikkaan. Tutkimukseen valittiin 21 informanttia muutamista Yhdysvaltain eteläisistä ja läntisistä osavaltioista. Informanttien haastattelunauhoitteista poimittiin analyysiin yhteensä 433 švaan F1- ja F2-formanttiarvot siten kuin ne esiintyivät sanassa the. Analyysissä havaittiin, että eteläisten puhujien švaat keskittyivät vokaalien [u,U] tuntumaan, kun taas läntisten informanttien švaat asettuivat vokaalien [i,u] väliin. Tulokset antoivat aihetta kysyä, onko eteläinen švaa sulautunut takavokaaleihin [u,U]. Kysymystä varten suoritettiin jatkotutkimus, johon valittiin yksi ensimmäisen tutkimuksen eteläisistä puhujista. Puhujalta mitattiin 66 švaan ja 45 [U]:n formantit. Näitä tarkastellessa löydettiin tilastollista viitettä siitä, että puhujan švaa oli saattanut sulautua vokaaliin [U]. Tulostensa pohjalta tutkielma ehdottaa, että the-sanassa esiintyvässä amerikanenglannin švaassa saattaa toteutua puhujan alueellista murretta mukaileva tavoitevaihe siitä huolimatta, että tämä vokaali on samanaikaisesti huomattavasti kontekstiinsa assimiloitunut. Tavoitevaihe näyttäisi lähtökohtaisesti sijoittuvan F2:ssa vokaalialueen keskelle, ollen kuitenkin eteläisten puhujien kohdalla altis siirtymään taaemmas kohti vokaalilaatuja [u,U].

«We need more women in managerial jobs» – Gender equality and management in the Nordic context : Deconstruction and critical perspectives

Focusing on the Nordic context, this article highlights complexities between gender equality discourse established at the societal level and discursive practice in organizations, particularly in relation to management, managing and managers. This research task is carried out by deconstructing a management text, and grounding the deconstruction in critical feminist literature. This analysis illustrates how managerial discourse is challenged and questioned by pro-egaliterian arguments in the Nordic context. However, it also demonstrates the pervasiveness of the gendered elements in managerial discourse, which relies on specific conceptions of parenthood where motherhood is constructed as problematic whereas fatherhood remains absent – and thus unproblematic. It is suggested that the ‘Nordic case’ provides a fruitful basis for similar studies in other societal contexts in Europe.

Estudo paramétrico da recuperação de petróleo pesado por aquecimento eletromagnético resistivo

Electrical resistive heating (ERH) is a thermal method used to improve oil recovery. It can increase oil rate and oil recovery due to temperature increase caused by electrical current passage through oil zone. ERH has some advantage compared with well-known thermal methods such as continuous steam flood, presenting low-water production. This method can be applied to reservoirs with different characteristics and initial reservoir conditions. Commercial software was used to test several cases using a semi-synthetic homogeneous reservoir with some characteristics as found in northeast Brazilian basins. It was realized a sensitivity analysis of some reservoir parameters, such as: oil zone, aquifer presence, gas cap presence and oil saturation on oil recovery and energy consumption. Then it was tested several cases studying the electrical variables considered more important in the process, such as: voltage, electrical configurations and electrodes positions. Energy optimization by electrodes voltage levels changes and electrical settings modify the intensity and the electrical current distribution in oil zone and, consequently, their influences in reservoir temperature reached at some regions. Results show which reservoir parameters were significant in order to improve oil recovery and energy requirement in for each reservoir. Most significant parameters on oil recovery and electrical energy delivered were oil thickness, presence of aquifer, presence of gas cap, voltage, electrical configuration and electrodes positions. Factors such as: connate water, water salinity and relative permeability to water at irreducible oil saturation had low influence on oil recovery but had some influence in energy requirements. It was possible to optimize energy consumption and oil recovery by electrical variables. Energy requirements can decrease by changing electrodes voltages during the process. This application can be extended to heavy oil reservoirs of high depth, such as offshore fields, where nowadays it is not applicable any conventional thermal process such as steam flooding

EVALUATING THE OIL SANDS RECLAMATION PROCESS: ASSESSING POLICY CAPACITY AND STAKEHOLDER ACCESS FOR GOVERNMENT AND NON-GOVERNMENTAL ORGANIZATIONS OPERATING IN ALBERTA’S OIL SANDS

By employing interpretive policy analysis this thesis aims to assess, measure, and explain policy capacity for government and non-government organizations involved in reclaiming Alberta's oil sands. Using this type of analysis to assess policy capacity is a novel approach for understanding reclamation policy; and therefore, this research will provide a unique contribution to the literature surrounding reclamation policy. The oil sands region in northeast Alberta, Canada is an area of interest for a few reasons; primarily because of the vast reserves of bitumen and the environmental cost associated with developing this resource. An increase in global oil demand has established incentive for industry to seek out and develop new reserves. Alberta's oil sands are one of the largest remaining reserves in the world, and there is significant interest in increasing production in this region. Furthermore, tensions in several oil exporting nations in the Middle East remain unresolved, and this has garnered additional support for a supply side solution to North American oil demands. This solution relies upon the development of reserves in both the United States and Canada. These compounding factors have contributed to the increased development in the oil sands of northeastern Alberta. Essentially, a rapid expansion of oil sands operations is ongoing, and is the source of significant disturbance across the region. This disturbance, and the promises of reclamation, is a source of contentious debates amongst stakeholders and continues to be highly visible in the media. If oil sands operations are to retain their social license to operate, it is critical that reclamation efforts be effective. One concern non-governmental organizations (NGOs) expressed criticizes the current monitoring and enforcement of regulatory programs in the oil sands. Alberta's NGOs have suggested the data made available to them originates from industrial sources, and is generally unchecked by government. In an effort to discern the overall status of reclamation in the oil sands this study explores several factors essential to policy capacity: work environment, training, employee attitudes, perceived capacity, policy tools, evidence based work, and networking. Data was collected through key informant interviews with senior policy professionals in government and non-government agencies in Alberta. The following are agencies of interest in this research: Canadian Association of Petroleum Producers (CAPP); Alberta Environment and Sustainable Resource Development (AESRD); Alberta Energy Regulator (AER); Cumulative Environmental Management Association (CEMA); Alberta Environment Monitoring, Evaluation, and Reporting Agency (AEMERA); Wood Buffalo Environmental Association (WBEA). The aim of this research is to explain how and why reclamation policy is conducted in Alberta's oil sands. This will illuminate government capacity, NGO capacity, and the interaction of these two agency typologies. In addition to answering research questions, another goal of this project is to show interpretive analysis of policy capacity can be used to measure and predict policy effectiveness. The oil sands of Alberta will be the focus of this project, however, future projects could focus on any government policy scenario utilizing evidence-based approaches.

Characterization of Chimney Flue Gas Flows : Flow Rate Measurements with Averaging Pitot Probes

Performance testing methods of boilers in transient operating conditions (start, stop and combustion power modulation sequences) need the combustion rate quantified to allow for the emissions to be quantified. One way of quantifying the combustion rate of a boiler during transient operating conditions is by measuring the flue gas flow rate. The flow conditions in chimneys of single family house boilers pose a challenge however, mainly because of the low flow velocity. The main objectives of the work were to characterize the flow conditions in residential chimneys, to evaluate the use of the Pitot-static method and the averaging Pitot method, and to develop and test a calibration method for averaging Pitot probes for low
