Vieillissement actif : le maintien à domicile des baby-boomers

Cette recherche s’intéresse aux enjeux de l’habitat de demain de la génération des baby-boomers, tout particulièrement ceux nés entre 1945 et 1953, qui arrivent aujourd’hui à la retraite. C’est au carrefour de la vision de ce que signifie habiter selon des auteurs comme Benoit Goetz ( 2011), des philosophes comme Heidegger (1958), Bachelard (1957), Benjamin (1955), Büber (1962) ou encore Deleuze (1980) d’une part, soulignant les facteurs de porosité et les liens aux autres, et d’autre part les caractéristiques des baby-boomers telles que présentées par Jean François Sirinelli (2003) et Josée Garceau (2012), que se situe la recherche. Cette génération informée entend rester active et pratique des « adeptions » qui influencent par les gestes un savoir habiter et par là son habitat. L’étude de terrain a sondé les aspirations des baby-boomers en ce qui concerne leur choix résidentiel pour l’avenir, pour comprendre sur quelles valeurs et vers quels buts leur projet se construit. Le choix de méthodologies qualitatives s’appuie sur le visionnement préalable d’un film récent : Et si on vivait tous ensemble. Des entretiens semi-dirigés, auprès de cinq baby-boomers, de 60 à 65 ans, effectués en deux phases avec verbatim approuvés,étaient basés sur trois thèmes : la mémoire, l’adeption et le projet. Entre autres résultats, sont confirmés avec variantes, plusieurs concepts théoriques, comme ceux de porosité et d’ouverture par la fenêtre à la fois physique et virtuelle, mais soulignent le spectre de la maison de retraite et des préoccupations financières concernant l’avenir d’un habitat nécessairement autonome. Cette génération imprégnée par le monde technologique veut avoir accès à tout ce que propose la modernité sans pour autant perdre le sens de l’historicité de leur vie. Nés dans un monde en bouillonnement, les baby-boomers ont réinventé chaque étape de leur existence, ce qui laisse préfigurer que cette génération s’apprête à réinventer la retraite et ses sites domiciliaires. Aussi l’approche design devra-t-elle complètement se renouveler pour ces nouveaux usagers.

Plan de negocio para el desarrollo de una nueva línea de producto en la empresa S.I.C.C.

La empresa S.I.C.C. (soluciones integrales para el campo del Caribe) con el fin de seguir desarrollando su concepto empresarial, surge la idea de crear una nueva línea de negocio con énfasis en la producción de quesos para vender a minoristas. Para empezar a desarrollar esta nueva idea, los dueños tienen en cuenta el conocimiento de productores artesanales de queso, a los cuales proveen de leche. Debe tenerse en cuenta que estos productores no tienen sus negocios formalizados, sino por el contrario son productores informales que realizan la producción de queso de manera artesanal en sus casas, en donde la forma de producción no es la más adecuada por cuestiones fitosanitarias, transporte inadecuado, entre otros. Para hacer efectivo el proyecto, la empresa nos plantea al grupo crear un proyecto para acoger a estos pequeños productores de queso y formalizar su actividad productiva dentro de la empresa S.I.C.C. con el fin de crear una nueva línea de producto dentro de la compañía en donde se beneficiaran los productores y la empresa como tal; a partir de lo anterior se requiere realizar una investigación y planeación en cuanto al sector lácteo, particularmente en cuanto a los quesos en la región de Sucre, específicamente en Sincelejo. El proyecto surge con el fin de seguir apoyando la visión de la empresa, en donde se plantea que la empresa llegue a ser líder en el sector forestal y agropecuario, a través del desarrollo y ejecución de proyectos que sean generadores de empleo y que garanticen un crecimiento social y económico de las regiones donde se ejecuten.

La muerte en la psicoterapia fenomenológico-existencial

El siguiente trabajo pretende, mediante la revisión de diferentes fuentes bibliográficas, mostrar las distintas categorías en las que la muerte se trabaja dentro de la psicoterapia fenomenológico existencial. Es así como se hace un recorrido por los antecedentes filosóficos de este enfoque psicoterapéutico, las diferentes escuelas que dentro de él se desarrollan y sus planteamientos frente a la muerte, las maneras de morir, la muerte y el ciclo vital, y los avances actuales como la Teoría del Manejo del Terror (TMT) . Todos estos elementos se revisan para después ser relacionados y así proponer una serie de acciones prácticas a llevar a cabo dentro del encuentro psicoterapéutico con miras a un trabajo adecuado y productivo con la muerte desde una perspectiva existencial.

La Costa Brava ante los nuevos retos del turismo

The first section of this paper summarises the most relevant charateristics of the contemporary tourist model, also called postfordist or postmodernist. In the second part the traditional tourist model developed in the Costa Brava in the past decades, is reviewed. Emphasising the saturation of tourist facilities on the coast line, expansive urban growth, thanks to a tolerant administration, poor complementary supply and concentrated demand in few markets and the proximity of Barcelona conurbation, stressed by second homes. In the third section, some strategies developed in recent years to readapt the Costa Brava to the new tendencies in tourism, are presented. Incorporation of the inland to the tourist product, new planning policics, lessening urban densities and height, and a change in mind in favour of protected natural areas, diversification of demand with new markets, specially form Eastern Europe (although this might be considered as a continuation of the traditional tourist model) and the emergence of local strategies oriented towards the creation of new tourist products based upon natural and cultural resources

Modificaciones tecnológicas para mejorar la seguridad y calidad del jamón curado

Se introdujeron varias modificaciones tecnológicas en la elaboración habitual del jamón curado español de cerdo blanco para mejorar su seguridad y calidad, así como para investigar la contribución relativa de los diversos procesos implicados en la calidad sensorial. Las modificaciones introducidas en cada uno de 3 experimentos (a, b, c) fueron: a) inoculación de un cultivo iniciador (CI) en la superficie del producto y el envasado del jamón al vacío durante la etapa de reposo (EV); b) aplicación de una atmósfera modificada con un contenido reducido de oxígeno (AMCRO) (durante la totalidad o la última parte del procesado) en dos procesos que diferían en las humedades relativas aplicadas; c) realización de un estufaje de 4 días a 35ºC y la aplicación repetida de pequeñas cantidades de grasa dorsal líquida sobre la superficie del jamón. En cada experimento, se siguió un diseño experimental de bloques incompletos para bloquear y evaluar el efecto de la materia prima en cada parámetro. La aplicación del CI evitó el crecimiento superficial de hongos, pero modificó el flavor del producto, dando lugar a la aparición de flavores impropios del jamón tradicional, al aumento de la incidencia de la coquera y a la reducción de la intensidad de notas características del mismo como el flavor añejo. Estos efectos fueron debidos a la acción directa del CI pero probablemente también a los cambios que provocó en la superficie del jamón, como la atenuación del "sudado" del jamón. El EV trajo consigo una reducción del crecimiento superficial de mohos; un mayor gradiente de humedad entre el interior y el exterior del jamón; una disminución de la pérdida de peso; un aumento del nitrógeno no proteico y cambios negativos en la textura, aspecto y flavor, como el aumento de la intensidad del velo blanco y del flavor a pienso, el aumento de la incidencia de la coquera y la atenuación del flavor añejo. Estos efectos fueron consecuencia del mayor contenido de humedad a que dio lugar dicha modificación tecnológica, de la potenciación de los efectos negativos del uso del CI, así como a los cambios que provocó en la superficie del jamón. El uso de una ACRO durante todo el proceso provocó un aumento del nitrógeno no proteico, una disminución de la concentración de óxidos de colesterol, un aumento de la intensidad del velo blanco y, en combinación con el uso de humedades relativas bajas, causó una disminución del crecimiento bacteriano y evitó el crecimiento de hongos, levaduras y ácaros en el interior y exterior del jamón y el desarrollo de la coquera. Asímismo, dio lugar a una drástica reducción de la intensidad del flavor del jamón debido a la disminución de la intensidad de la oxidación lipídica. Cuando esta ACRO se aplicó únicamente al final del proceso, se consiguió la eliminación de las formas móviles de los ácaros y la disminución de la intensidad de la coquera y el producto resultante poseía un flavor algo más intenso que aquél sometido a una ACRO durante todo el proceso. El aumento de la temperatura de 25-27 ºC a 35 ºC durante 4 días no tuvo ningún efecto sobre los parámetros estudiados. La aplicación de la grasa líquida en la superficie del jamón evitó el secado excesivo en superficie, previno el desarrollo de la coquera y causó un aumento de la intensidad del flavor añejo y una reducción de la incidencia de notas negativas como el tostado, hechos que indican que la liberación de grasa líquida en el jamón ("sudado") constituye un fenómeno determinante en su calidad sensorial. La materia prima fue el factor que afectó a un mayor número de parámetros.

Envelhecimento bem-sucedido : processo de interação enfermeiro-pessoa idosa em cuidados de saúde primários

Com o envelhecimento demográfico e o natural aumento dos cuidados de enfermagem no âmbito gerontológico surge o interesse em responder como é que o enfermeiro interage com a pessoa idosa para que esta utilize a sua essência evidenciando comportamentos protetores e promotores de envelhecimento bem-sucedido? E ao objetivo: compreender o processo da interação enfermeiro-pessoa idosa que conduz à utilização de comportamentos protetores e promotores de envelhecimento bem-sucedido. Trata-se de um estudo naturalista de paradigma qualitativo, de pensamento indutivo, desenvolvido num contexto de cuidados de saúde primários. Observámos o processo de interação entre enfermeiro-pessoa idosa num Agrupamento de Centros de Saúde e em Centros de Dia/Convívio e completámos a informação com entrevista. Utilizámos o método de análise grounded theory segundo Corbin & Strauss[1] que prevê a triangulação de dados bem como o recurso a amostragem teórica. A interação enfermeiro-pessoa idosa estabelece-se num processo conjunto de recriação do cuidado gerontológico predispondo, favorecendo e reforçando o conhecimento sobre o cerne da vida. A pessoa idosa objeto de cuidados do enfermeiro vai construindo o seu vivido caminhando para a integridade, estabelecendo interação individual e social e intensificando vivências. De todo este processo de interação emerge o conceito central: clarificação do vivido.

Inulin-type fructans in healthy aging

Worldwide, the population is aging, with estimates of 1 billion people aged 60 y or over within the next 20 y. With aging comes a reduction in overall health and increased morbidity and mortality due to infectious disease. Mortality due to gastrointestinal infections is up to 400 times higher in the elderly compared with younger adults. Recent studies have shown that the gut microbiota changes in old age, with an increased number of bacterial groups represented in the predominant elderly gut microbiota. This change in species "evenness" coincides with parallel changes in immune function, diet, and lifestyle and may contribute to disease susceptibility and severity in old age. The intestinal microbiota may thus be identified as an important target for improving health through reduced disease risk. Here, the application of prebiotics, especially the inulin-type fructans, and synbiotics (prebiotics combined with efficacious probiotic strains) will be discussed in terms of microbiota modulation and impact on disease risk in the aged population. Recent human intervention studies have confirmed the microbiota modulatory capability of the inulin-type fructans in the elderly and there is some evidence for reduced risk of disease. However, there is a need for more and larger human intervention studies to determine the efficacy of prebiotics in the elderly, particularly studies that take advantage of recent high resolution analytical methodologies like metabonomics, to shed light on possible prebiotic mechanisms of action.

Green marketing in housing: reality or rhetoric?

All new homes in the UK will be required to be zero carbon from 2016. Housing sector bodies and individual housing developers are championing a transition from traditional marketing to green marketing approaches to raise consumer awareness of the benefits of low and zero carbon homes. On-site sales teams on housing developments form a central interface between the developer and potential buyers. These teams, then, have a critical role in the success or otherwise of the developers’ green marketing strategies. However, there is a dearth of empirical research that explores the actual attitudes and practices of these teams. An exploratory case study approach was adopted. The data collection consisted of reviewing relevant company documentation and semi-structure interviews with the on-site sales teams from six housing developments. The findings from two case studies suggest that the sales teams do have potential to forge a bridge between the design / production and consumption spheres in the way that consumers understand and appreciate, but further work is required. The sales teams’ practices were constrained by the incumbent, traditional marketing logic that rotates around issues such as location and selling price. The sales teams appeared to adopt a strategy of a restriction of information about the benefits of low and zero carbon homes to not disturb the prevailing logic. Further, the sales teams justify this insulating mechanism by the argument that consumers are not interested in those benefits. This rhetoric may be driving a real wedge between the design / production and consumption spheres to the detriment of the consumer and, in the longer term, the house builder itself.

Time-dependent gel to gel transformation of a peptide based supramolecular gelator

A dipeptide with a long fatty acid chain at its N-terminus gives hydrogels in phosphate buffer in the pH range 7.0–8.5. The hydrogel with a gelator concentration of 0.45% (w/v) at pH 7.46 (physiological pH) provides a very good platform to study dynamic changes within a supramolecular framework as it exhibits remarkable change in its appearance with time. Interestingly, the first formed transparent hydrogel gradually transforms into a turbid gel within 2 days. These two forms of the hydrogel have been thoroughly investigated by using small angle X-ray scattering (SAXS), powder X-ray diffraction (PXRD), field emission scanning electron microscopic (FE-SEM) and high-resolution transmission electron microscopic (HR-TEM) imaging, FT-IR and rheometric analyses. The SAXS and low angle PXRD studies substantiate different packing arrangements for the gelator molecules for these two different gel states (the freshly prepared and the aged hydrogel). Moreover, rheological studies of these two gels reveal that the aged gel is stiffer than the freshly prepared gel.

Detecting defects in UK new-build housing: a learning perspective

House builders play a key role in controlling the quality of new homes in the UK. The UK house building sector is, however, currently facing pressures to expand supply as well as conform to tougher low carbon planning and Building Regulation requirements; primarily in the areas of sustainability. There is growing evidence that the pressure the UK house building industry is currently under may be eroding build quality and causing an increase in defects. It is found that the prevailing defect literature is limited to the causes, pathology and statistical analysis of defects (and failures). The literature does not extend to examine how house builders individually and collectively, in practice, collect and learn from defects experience in order to reduce the prevalence of defects in future homes. The theoretical lens for the research is organisational learning. This paper contributes to our understanding of organisational learning in construction through a synthesis of current literature. Further, a suitable organisational learning model is adopted. The paper concludes by reporting the research design of an ongoing collaborative action research project with the National House Building Council (NHBC), focused on developing a better understanding of house builders’ localised defects analysis procedures and learning processes.

Promoting behaviour change through personalized energy feedback in offices

A body of research suggests that the provision of energy feedback information to building users can elicit significant energy reductions through behaviour change. However, most studies have focused on energy use in homes and the assessment of interventions and technologies, to the neglect of the non-domestic context and broader issues arising from the introduction of feedback technologies. To address this gap, a non-domestic case study explores the delivery of personalized energy feedback to office workers through a novel system utilizing wireless technologies. The research demonstrates advantages of monitoring occupancy and quantifying energy use from specific behaviours as a basis for effective energy feedback; this is particularly important where there are highly disaggregated forms of energy use and a range of locations for that activity to take place. Quantitative and qualitative data show that personalized feedback can help individuals identify energy reduction opportunities. However, the analysis also highlights important contextual barriers and issues that need to be addressed when utilizing feedback technologies in the workplace. If neglected, these issues may limit the effective take-up of feedback interventions.

Ultrastructural Aspects of Female Aging Wistar Rat Epithelium Tongue: A HRSEM and TEM Study

Background: There is general consensus that the effects of intrinsic aging on the oral mucosa are relatively small, though potentially important to understanding the pathologies present in the aged animals. Objective: In this paper, the development of dorsal surface of rat tongue was examined using transmission electron microscopy (TEM) and high-resolution scanning electron microscopy (HRSEM) in order to understand the age-related structural and ultrastructural changes experimentally. Methods: In this study, we used female rats 75 and 720 days old (adult and aging). Tissues of rat tongue were prepared and the specimens submitted to HRSEM and TEM techniques. Results: The analysis of HRSEM and TEM demonstrated that the same characteristic keratinous epithelium was found in aging animals, however with some modifications. Conclusion: We agree that there are obvious changes in the oral mucosa with aging and these modifications can be observed starting from the ultrastructural aspects. Copyright (C) 2009 S.

Individuell utprovning av inkontinenshjälpmedel i kommunala särskilda boenden

The purpose of this study was to examine the extent to which incontinence aids, used in local authority/municipal nursing homes, were adapted to the resident’s urine-leakage volume and to find out how nurses perceived the current situation concerning individual testing of incontinence aids in municipal nursing homes. The study method was a quantitative empirical study and was carried out in two phases. The first phase was a weighing test, carried out in three nursing homes, whereby the incontinence aids used by 25 residents during a 48 hour period were weighed. The second phase was the completion of a questionnaire by the municipal nurses working in the same local authority. The questionnaire covered: the division of responsibilities; routines for testing incontinence aids, and the level of knowledge concerning individual incontinence aid testing. Only 22 % of the pads used during the observation were properly adapted to the patients’ urinary leakage volume, while 76 % of incontinence aids were larger than necessary in relation to the real volume of urinary leakage. The municipal nurses, who have a key role and formal responsibility for individual incontinence aid testing, considered that there was insufficient knowledge within the organisation concerning individual incontinence aid testing, and that the division of responsibilities in this area was unclear. There were great variations relating to the extent of the nurses’ involvement in individual incontinence aid testing, and the nurses stated that increased involvement in individual incontinence aid testing was dependent on more time being made available for this task. Only a minority of the nurses thought that the requisitioning of incontinence aids was preceded by individual testing of the incontinence pads within the organisation. The majority of nurses considered that this was not the case or were unsure of the situation.

Energieffektivisering av klimatskal med hänsyn till kulturhistorisk värdering : Fallstudier av tre befintliga småhus från 1900-talet ur bevarandesynpunkt

Allt hårdare lagkrav gör att det är svårt att energieffektivisera befintliga byggnader utan att förändra deras utseende. Syftet med examensarbetet är att utreda hur stor energieffektivisering, för tre befintliga småhus uppförda under 1900-talet, som är möjlig att uppnå genom förbättring av byggnadernas klimatskal, det vill säga tak, väggar, golv, fönster och dörrar, utan att förvanska byggnadernas utseende och samtidigt bevara deras kulturhistoriska värden. Arbetet bestod av en förstudie där tre byggnader identifierades, ett undersökningsskede där information om byggnaderna togs fram och ett slutsatsskede där energibesparande åtgärdsförslag togs fram och utvärderades. Byggnader som var goda representanter för sin tid och stil söktes. Byggnader från 1910-talet, 1930-talet och 1970-talet, lokaliserades. Sedan gjordes det fallstudier med intervjuer och inventeringar. För att utreda byggnadens klimatskal utfördes u-värdesberäkningar och energiberäkningar av befintliga byggander och byggnader baserade på föreslagna åtgärdsförslag. Ingen av byggnaderna nådde efter föreslagna åtgärder ner till passivhuskravet 59 kWh/år/m2 Atemp eller BBR-kravet 110 kWh/år/m2 Atemp för en byggnads specifika energianvändning. Den största möjliga energieffektivisering för de tre byggnaderna uppförda under 1900-talet, som är möjlig att uppnå utan att förvanska byggnadernas utseende och samtidigt bevara deras kulturhistoriska värden är 13,0 kWh/år/m2 Atemp, 49,7 kWh/år/m2 Atemp respektive 64,8 kWh/år/m2 Atemp. Slutsatser från arbetet är att byggnader från 1910-tal kan åtgärdas genom att isolera fönstren, sätta dit en extra dörr på insidan av ytterdörren samt tilläggsisolera snedtaket. Byggnader från 1930-tal kan åtgärdas genom att isolera fönstren med en isolerruta på insidan av fönstret och dörrarna med en extra dörr på insidan av ytterdörren. Byggnader från 1970-tal kan åtgärda fönstren genom att byta ut dem till energifönster, ingen åtgärd för golvet men fasaden isoleras utvändigt med vakuumisolering. Byggnaden från 1970-talet klarade sig bäst i jämförelsen eftersom den var i autentiskt skick från början vilket gjorde att förbättringen blev större än för till exempel byggnaden från 1910-talet som redan var ombyggd innan åtgärder föreslogs.

Self-reported symptoms and motor tests via telemetry in a 36-month levodopa-carbidopa intestinal gel infusion trial

Objective To investigate if a home environment test battery can be used to measure effects of Parkinson’s disease (PD) treatment intervention and disease progression. Background Seventy-seven patients diagnosed with advanced PD were recruited in an open longitudinal 36-month study at 10 clinics in Sweden and Norway; 40 of them were treated with levodopa-carbidopa intestinal gel (LCIG) and 37 patients were candidates for switching from oral PD treatment to LCIG. They utilized a mobile device test battery, consisting of self-assessments of symptoms and objective measures of motor function through a set of fine motor tests (tapping and spiral drawings), in their homes. Both the LCIG-naïve and LCIG-non-naïve patients used the test battery four times per day during week-long test periods. Methods Assessments The LCIG-naïve patients used the test battery at baseline (before LCIG), month 0 (first visit; at least 3 months after intraduodenal LCIG), and thereafter quarterly for the first year and biannually for the second and third years. The LCIG-non-naïve patients used the test battery from the first visit, i.e. month 0. Out of the 77 patients, only 65 utilized the test battery; 35 were LCIG-non-naïve and 30 LCIG-naïve. In 20 of the LCIG-naïve patients, assessments with the test battery were available during oral treatment and at least one test period after having started infusion treatment. Three LCIG-naïve patients did not use the test battery at baseline but had at least one test period of assessments thereafter. Hence, n=23 in the LCIG-naïve group. In total, symptom assessments in the full sample (including both patient groups) were collected during 379 test periods and 10079 test occasions. For 369 of these test periods, clinical assessments including UPDRS and PDQ-39 were performed in afternoons at the start of the test periods. The repeated measurements of the test battery were processed and summarized into scores representing patients’ symptom severities over a test period, using statistical methods. Six conceptual dimensions were defined; four subjectively-reported: ‘walking’, ‘satisfied’, ‘dyskinesia’, and ‘off’ and two objectively-measured: ‘tapping’ and ‘spiral’. In addition, an ‘overall test score’ (OTS) was defined to represent the global health condition of the patient during a test period. Statistical methods Change in the test battery scores over time, that is at baseline and follow-up test periods, was assessed with linear mixed-effects models with patient ID as a random effect and test period as a fixed effect of interest. The within-patient variability of OTS was assessed using intra-class correlation coefficient (ICC), for the two patient groups. Correlations between clinical rating scores and test battery scores were assessed using Spearman’s rank correlations (rho). Results In LCIG-naïve patients, mean OTS compared to baseline was significantly improved from the first test period on LCIG treatment until month 24. However, there were no significant changes in mean OTS scores of LCIG-non-naïve patients, except for worse mean OTS at month 36 (p<0.01, n=16). The mean scores of all subjectively-reported dimensions improved significantly throughout the course of the study, except ‘walking’ at month 36 (p=0.41, n=4). However, there were no significant differences in mean scores of objectively-measured dimensions between baseline and other test periods, except improved ‘tapping’ at month 6 and month 36, and ‘spiral’ at month 3 (p<0.05). The LCIG-naïve patients had a higher within-subject variability in their OTS scores (ICC=0.67) compared to LCIG-non-naïve patients (ICC=0.71). The OTS correlated adequately with total UPDRS (rho=0.59) and total PDQ-39 (rho=0.59). Conclusions In this 3-year follow-up study of advanced PD patients treated with LCIG we found that it is possible to monitor PD progression over time using a home environment test battery. The significant improvements in the mean OTS scores indicate that the test battery is able to measure functional improvement with LCIG sustained over at least 24 months.
