Från ord till handling : En kvalitativ studie om värdegrund och socialt innehåll för äldre på särskilt boende

Socialstyrelsens brukarundersökning visar att äldre som bor på särskilt boende är mest missnöjda med de aktiviteter och den sociala samvaron som verksamheten erbjuder. Äldreomsorgen bygger på den nationella värdegrunden som innefattar att den äldre ska få leva ett värdigt liv och känna välbefinnande, men det är inte klart hur denna värdegrund påverkar personalens arbetssätt eller de sociala aktiviteter som erbjuds. Vår studie angriper denna fråga. Fem särskilda boenden var representerade både från kommunala och privata vårdgivare i två olika kommuner. Semistrukturerade intervjuer genomfördes med de särskilda boendes enhetschefer, som sedan transkriberades och tematiskt analyserades. Vårt resultat tyder på att den nationella värdegrunden inom äldreomsorgen tolkas olika på alla de särskilda boendena. Alla enhetschefer la stor vikt på personcentrerad vård, men trots det så erbjöd man liknade sociala aktiviteter ofta då som gruppaktivitet. Resultaten diskuterar vi med hänvisning till Aktivitetsteorin och Gerotranscendenceteorin.

Novel catalyst systems based on Ni(II), Ti(IV), and Cr(III) complexes for oligo-and polymerization of ethylene

The complex of Brookhart Ni(α-diimine)Cl2 (1) (α-diimine = 1,4-bis(2,6- diisopropylphenyl)-acenaphthenediimine) has been characterized after impregnation on silica (S1) and MAO-modified silicas (4.0, 8.0 and 23.0 wts.% Al/SiO2 called S2, S3 and S4, respectively). The treatment of these heterogeneous systems with MAO produces some active catalysts for the polymerization of the ethylene. A high catalytic activity has been gotten while using the system supported 1/S3 (196 kg of PE/mol[Ni].h.atm; toluene, Al/Ni = 1000, 30ºC, 60 min and atmospheric pressure of ethylene). The effects of polymerization conditions have been tested with the catalyst supported in S2 and the best catalytic activity has been gotten with solvent hexane, MAO as cocatalyst, molar ratio Al/Ni of 1000 and to the temperature of 30°C (285 kg of PE/mol[Ni].h.atm). When the reaction has been driven according to the in situ methodology, the activity practically doubled and polymers showed some similar properties. Polymers products by the supported catalysts showed the absence of melting fusion, results similar to those gotten with the homogeneous systems by DSC analysis. But then, polymers gotten with the transplanted system present according to the GPC’s curves the polydispersity (MwD) varies between 1.7 and 7.0. A polyethylene blend (BPE/LPE) was prepared using the complex Ni(α-diimine)Cl2 (1) (α-diimine = 1,4-bis(2,6-diisopropylphenyl)-acenaphthenediimine) and {TpMs*}TiCl3 (2) (TpMs* = hydridobis(3-mesitylpyrazol-1-yl)(5-mesitylpyrazol-1-yl)) supported in situ on MAO-modified silica (4.0 wts. -% Al/SiO2, S2). Reactions of polymerization of ethylene have been executed in the toluene in two different temperatures (0 and 30°C), varying the molars fraction of nickel (xNi), and using MAO as external cocatalyst. To all temperatures, the activities show a linear variation tendency with xNi and indicate the absence of the effect synergic between the species of nickel and the titanium. The maximum of activity have been found at 0°C. The melting temperature for the blends of polyethylene produced at 0 °C decrease whereas xNi increases indicating a good compatibility between phases of the polyethylene gotten with the two catalysts. The melting temperature for the blends of polyethylene showed be depend on the order according to which catalysts have been supported on the MAO-modified silica. The initial immobilization of 1 on the support (2/1/S2) product of polymers with a melting temperature (Tm) lower to the one of the polymer gotten when the titanium has been supported inicially (1/2/S2). The observation of polyethylenes gotten with the two systems (2/1/S2 and 1/2/S2) by scanning electron microscopy (SEM) showed the spherical polymer formation showing that the spherical morphology of the support to been reproduced. Are described the synthesis, the characterization and the catalytic properties for the oligomerization of the ethylene of four organometallics compounds of CrIII with ligands ([bis[2-(3,5-dimethyl-1-pyrazolyl)ethyl]amine] chromium (III) chloride (3a), [bis[2-(3,5- dimethyl-l-pyrazolyl)ethyl]benzylamine] chromium (III) chloride (3b), [bis[2-(3,5-dimethyl-lpyrazolyl) ethyl]ether] chromiun(III)chloride (3c), [bis[2-(3-phenyl-lpyrazolyl) ethyl]ether]chromiun(III)chloride (3d)). In relation of the oligomerization, at exception made of the compounds 3a, all complex of the chromium showed be active after activation with MAO and the TOF gotten have one effect differentiated to those formed with CrCl3(thf)3. The coordination of a tridentate ligand on the metallic center doesn't provoke any considerable changes on the formation of the C4 and C6, but the amount of C8 are decrease and the C10 and C12+ have increased. The Polymers produced by the catalyst 3a to 3 and 20 bar of ethylene have, according to analyses by DSC, the temperatures of fusion of 133,8 and 136ºC respectively. It indicates that in the two cases the production of high density polyethylene. The molar mass, gotten by GPC, is 46647 g/mols with MwD = 2,4 (3 bar). The system 3c/MAO showed values of TOF, activity and selectivity to different α-olefins according to the pressure of ethylene uses. Himself that shown a big sensibility to the concentration of ethylene solubilized.

A nova parceria para o desenvolvimento da África : NEPAD, paradigma para o desenvolvimento

Os chefes de Estado africanos, após a transformação da Organização da Unidade Africana em União Africana, propuseram a Nova Parceria para o Desenvolvimento da África (NEPAD), como um quadro para uma nova relação de parceria entre a África e a comunidade internacional. Neste sentido de nova parceria, os dirigentes africanos se engajaram em promover nos seus países, na sua região e no Continente, a paz, a segurança, a democracia, a boa governança, o respeito dos direitos humanos e uma saudável gestão econômica, como uma estratégia para orientar o desenvolvimento da África no século XXI. A NEPAD suscitou uma reação positiva na comunidade internacional. A NEPAD repousa sobre fundamentos de desenvolvimento duradouro no Continente, sem os quais tornam-se impossíveis resultados concretos. Entre esses fundamentos podemos citar: a democracia, a boa governança, a governança econômica e a governança das empresas. Para alcançar o objetivo, a NEPAD propõe reformas institucionais como a utilização de meios de avaliação que permitem instaurar definitivamente a boa governança nas estruturas do Estado.

O papel do turismo nos conflitos urbanos da cidade do Natal/RN: a história que ninguém quer contar

La présente étude a comme objectif comprendre la relation entre l implantation et le développement du Tourisme à Natal et les conflits urbains établits entre 2006 et 2010 et publiés par les médias imprimés, élaborant ses impacts dans le quotidien des résidents. Tandis qu une relecture partielle de la méthode régressive-progressive développée par le philosophe français Henri Lefebvre, cherche à recouper du présent, des contradictions qui promeuvent des réactions dans le quotidien de la ville; ainsi qu identifier des moments du passé qui puissent contribuer à sa compréhension. Aujourd hui, nous avons les médias, comme principale source pour observer la perception locale des problèmes causés par l espace conçu, à partir des actions de l État référentes à l activité. Par rapport au passé, ces situations sont recherchées dans des sources secondaires, mettant en évidence le dialogue avec le Relatório Conflitos Urbanos (Rapport Conflits Urbains) à Natal-1976-1986 (ANDRADE et al.,1986), qui présente les conflits existants à des moments qui ont précédé ou ont acompagné le début du développement de l activité au RN, spécialement à Natal. Alors que dans la contribution à la compréhension du rôle du Tourisme dans l apparition de conflits urbains de la ville sont aussi inclues nos coupures vécues, des actions de l État par rapport à la consolidation, ainsi comme pour les conflits qui se sont plus demarqués ou qui ont conduit à la réaction de la population de la ville pendant les périodes analysées. Au final, on cherche à démontrer les limites de la responsabilité de l activité touristique dans l urgence des principaux conflits urbains dans la ville. L analyse des données de la recherche, avec l identification des conflits urbains de Natal et sa relation avec le Tourisme; la présentation des conflits par rapport à la localisation, fréquence et son encadrement dans les catégories de l analyse adoptée; l identification des agents intéressés et la relation entre eux; ont amené à la confirmation de l hypothèse proposée. De cette façon, en prenant en compte les coupures temporelles et spatiales, la source de recherche et la méthodologie adoptées, nous arrivons à la conclusion que l activité touristique à Natal n est pas directement responsable de l apparition des conflits urbains de la ville

Formação de professores na Província do Grão-Pará: os discursos de seus administradores acerca da necessidade de se instaurar uma Escola Normal (1838 – 1871)

Este trabalho tem por tema o processo de criação e consolidação discursiva da Escola Normal do Pará. Nosso objeto de pesquisa, portanto, são os discursos dos Presidentes da Província do Grão-Pará acerca da necessidade de se implantar, na capital da Província, cidade de Belém, uma Escola Normal destinada ao preparo específico de professores. Deste modo, nosso objetivo foi o de analisar os discursos dos Presidentes, de forma que pudéssemos depreender os objetivos destes para a implantação de uma Escola Normal, assim como as influências externas e internas, e, mais detidamente, a ambiência política e social em que foi constituído estes discursos em favor do “modelo” normalista de formação de professores. Como metodologia utilizamos a pesquisa documental a partir da análise do discurso, por meio da perspectiva de Mikhail Bakhtin. Utilizamos como aporte teórico para a compreensão de nosso objeto a escola dos Annales, em especial, sua primeira e terceira gerações, relacionadas a compreensão das antíteses antigo/moderno, passado/presente e progresso/reação. Dessa forma, concatenamos os enunciados presidenciais ao que fora debatido e proposto pelos filósofos e políticos franceses do final do século XVIII, onde identificamos com maior ênfase, os pressupostos teóricos apresentados pelo Marquês de Condorcet, em seu Rapport de 1792, quando estabeleceu teoricamente as bases da instrução nacional francesa, fundamentada na ideologia iluminista do período. Procuramos delinear ainda a ambiência política, econômica e social da Província do Grão-Pará, de forma que pudéssemos situar nosso objeto no contexto histórico específico da Província, uma vez que, assim como em outras Províncias do Império, a Escola Normal emerge de uma ambiência política e econômica favoráveis a sua implantação. Situamos nosso objeto de investigação nas nuanças políticas e sociais que se configuraram nas disputas entre liberais e conservadores que contrastavam seus projetos de sociedade e de instrução pública, gerando grande disputa política e ideológica. Destarte, concluímos que a Escola Normal do Pará nasce dessa intricada questão de disputas políticas e ideológicas entre conservadores e liberais, de forma que a organização da mesma esteve em função dos objetivos daqueles que estiveram à frente do Governo da Província, ratificando a influência europeia entre a elite dirigente daquele período, bem como a supremacia do modelo normalista de formação de professores entre essa classe dirigente, que o considerava como eficiente sistema de preparo e habilitação de professores, uma que já havia sido implantado em outras Províncias do Império desde 1835, que assim como a experiência do Grão-Pará, estiveram em meio a essas disputas políticas e ideológicas, bem como sob uma ambiência econômica que as possibilitaram. Cumpre destacarmos ainda as contradições do discurso e da prática dos Presidentes da Província, que pautavam seus debates nos pressupostos iluministas de ilustração do povo à luz da moral, da razão e do cientificismo, mas o que verificamos fora a falta de investimentos no sistema de instrução pública da Província que atendessem a necessidade de implantação de escolas no interior do Grão-Pará, assim como de melhores ordenados para os professores e a implantação de políticas de formação e aperfeiçoamento destes. Além de manterem um sistema de instrução pública excludente, pois em nenhum momento de seus discursos e debates se pensou em uma instrução que estivesse ao alcance dos negros, seja negros livres ou escravizados, muito menos sobre a instrução de indígenas.

Stellar Models in General Relativity

Neutron stars are some of the most fascinating objects in Nature. Essentially all aspects of physics seems to be represented inside them. Their cores are likely to contain deconfined quarks, hyperons and other exotic phases of matter in which the strong interaction is the dominant force. The inner region of their solid crust is penetrated by superfluid neutrons and their magnetic fields may reach well over 1012 Gauss. Moreover, their extreme mean densities, well above the densities of nuclei, and their rapid rotation rates makes them truly relativistic both in the special as well as in the general sense. This thesis deals with a small subset of these phenomena. In particular the exciting possibility of trapping of gravita-tional waves is examined from a theoretical point of view. It is shown that the standard condition R < 3M is not essential to the trapping mechanism. This point is illustrated using the elegant tool provided by the optical geometry. It is also shown that a realistic equation of state proposed in the literature allows stable neutron star models with closed circular null orbits, something which is closely related to trapped gravitational waves. Furthermore, the general relativistic theory of elasticity is reviewed and applied to stellar models. Both static equilibrium as well as radially oscillating configurations with elasticsources are examined. Finally, Killing tensors are considered and their applicability to modeling of stars is discussed

Mechanical non-surgical treatment of peri-implantitis: a single-blinded randomized longitudinal clinical study. II. Microbiological results

BACKGROUND: Peri-implantitis is common in patients with dental implants. We performed a single-blinded longitudinal randomized study to assess the effects of mechanical debridement on the peri-implant microbiota in peri-implantitis lesions. MATERIALS AND METHODS: An expanded checkerboard DNA-DNA hybridization assay encompassing 79 different microorganisms was used to study bacterial counts before and during 6 months following mechanical treatment of peri-implantitis in 17 cases treated with curettes and 14 cases treated with an ultrasonic device. Statistics included non-parametric tests and GLM multivariate analysis with p<0001 indicating significance and 80% power. RESULTS: At selected implant test sites, the most prevalent bacteria were: Fusobacterium nucleatum sp., Staphylococci sp., Aggregatibacter actinomycetemcomitans, Helicobacter pylori, and Tannerella forsythia. 30 min. after treatment with curettes, A. actinomycetemcomitans (serotype a), Lactobacillus acidophilus, Streptococcus anginosus, and Veillonella parvula were found at lower counts (p<0.001). No such differences were found for implants treated with the ultrasonic device. Inconsistent changes occurred following the first week. No microbiological differences between baseline and 6-month samples were found for any species or between treatment study methods in peri-implantitis. CONCLUSIONS: Both methods failed to eliminate or reduce bacterial counts in peri-implantitis. No group differences were found in the ability to reduce the microbiota in peri-implantitis.

Comportement thermique des géopolymères obtenus à partir d'une argile kaolinite

The aim of this work is to study the thermal behavior of geopolymers derived from kaolinite (clay). The geopolymers were characterized by various technics: Thermal analysis (DTA, TGA and dilatometer), X-ray diffractography (XRD), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). Certain physical properties of the products were equally determined: linear shrinkage of curing, percentage of water absorption and compressive strength. The results obtained after drying and thermal treatment showed that the products preserved their initial forms, but showed variable colours based on the temperatures they were treated at. The products obtained at 90, 300 and 500 °C contained hydroxysodalite. The synthesis of geopolymers is not complete at 300 °C (presence of kaolinite in the material) but the products obtained are quite consolidated. The geopolymers obtained have weak values of linear shrinkage of curing (less than 0.6 %) and the compressive strength increases from room temperature (4.9 Mpa) up to 400 °C (8.9 MPa) then becomes constant between 400 and 500 °C. The combination of results demonstrates the efficiency of the temperature parameter during the synthesis of geopolymers based on kaolinite. // L’objet de ce travail est l’étude du comportement thermique des géopolymères à base d’une argile kaolinite. Les produits obtenus ont été caractérisés au moyen de plusieurs techniques : analyses thermiques (ATD, ATG et dilatométrie), microscopie électronique à balayage (MEB), analyse par diffraction de rayons X (DRX), analyse infrarouge par transformée de Fourier (IRTF). Certaines propriétés physiques des produits obtenus ont également été déterminées : retrait linéaire de cuisson, pourcentage d’absorption d’eau et résistance à la compression. Les résultats obtenus montrent qu’après le séchage et à la fin du traitement thermique, les éprouvettes des produits conservent leur forme initiale mais présentent une variation de couleur en fonction de la température de traitement. Les produits obtenus à 90, 300 et 500 °C contiennent de l’hydroxysodalite. La réaction de synthèse géopolymère n’est pas encore terminée au moins à 300 °C (présence de kaolinite dans le matériau) mais les produits obtenus sont assez consolidés. Les géopolymères obtenus présentent de faibles valeurs de retrait linéaire de cuisson (inférieure à 0,6 %) et une résistance à la compression qui augmente de la température ambiante (4,9 MPa) jusqu’à 400 °C (8,9 MPa) puis devient constante entre 400 et 500 °C. L’ensemble de ces résultats permet de mettre en exergue l’efficacité du paramètre « température » au cours de la synthèse des géopolymères à base de kaolinite.

Das Burnout-Syndrom: eine medizinische Perspektive

The burnout syndrome is a heterogeneous concept mostly understood as a complex of symptoms, primarily exhaustion, in response to prolonged emotional and interpersonal stress at work. The prevalence of burnout is considerably high in Swiss primary care physicians. In spite of its vague definition, burnout is a serious stress disease with many associated medical problems and high economic costs. Previous recommendations for the psychosomatic management of patients with functional somatic syndromes also apply to burnout treatment. These are complemented by more specific interventions targeting job stress related factors. Relapse prevention focuses on early recognition of warning signs and is an ongoing process.

Mechanical non-surgical treatment of peri-implantitis: a double-blind randomized longitudinal clinical study. I: clinical results

BACKGROUND: Peri-implantitis is a frequent finding in patients with dental implants. The present study compared two non-surgical mechanical debridement methods of peri-implantitis. MATERIAL AND METHODS: Thirty-seven subjects (mean age 61.5; S.D+/-12.4), with one implant each, demonstrating peri-implantitis were randomized, and those treated either with titanium hand-instruments or with an ultrasonic device were enrolled. Data were obtained before treatment, and at 1, 3, and 6 months. Parametric and non-parametric statistics were used. RESULTS: Thirty-one subjects completed the study. The mean bone loss at implants in both groups was 1.5 mm (SD +/-1.2 mm). No group differences for plaque or gingival indices were found at any time point. Baseline and 6-month mean probing pocket depths (PPD) at implants were 5.1 and 4.9 mm (p=0.30) in both groups. Plaque scores at treated implants decreased from 73% to 53% (p<0.01). Bleeding scores also decreased (p<0.01), with no group differences. No differences in the total bacterial counts were found over time. Higher total bacterial counts were found immediately after treatment (p<0.01) and at 1 week for ultrasonic-treated implants (p<0.05). CONCLUSIONS: No group differences were found in the treatment outcomes. While plaque and bleeding scores improved, no effects on PPD were identified.

5-Lipoxygenase is phosphorylated by p38 kinase-dependent MAPKAP kinases

5-lipoxygenase (5-LO) catalyzes the initial steps in the formation of leukotrienes, a group of inflammatory mediators derived from arachidonic acid (AA). Here we describe that activation of p38 mitogen-activated protein kinase in human polymorphonuclear leukocytes and in Mono Mac 6 cells leads to activation of downstream kinases, which can subsequently phosphorylate 5-LO in vitro. Different agents activated the 5-LO kinase activities, including stimuli for cellular leukotriene biosynthesis (A23187, thapsigargin, N-formyl-leucyl-phenylalanine), compounds that up-regulate the capacity for leukotriene biosynthesis (phorbol 12-myristate 13-acetate, tumor necrosis factor α, granulocyte/macrophage colony-stimulating factor), and well known p38 stimuli as sodium arsenite and sorbitol. For all stimuli, 5-LO kinase activation was counteracted by SB203580 (3 μM or less), an inhibitor of p38 kinase. At least two p38-dependent 5-LO kinase activities were found. Based on migration properties in in-gel kinase assays and immunoreactivity, one of these was identified as mitogen-activated protein kinase-activated protein kinase 2 (MAPKAP kinase 2). The other appeared to be MAPKAP kinase 3; however, it could not be excluded that also other p38-dependent kinases contributed. When polymorphonuclear leukocytes were incubated with sodium arsenite (strong activator of 5-LO kinases), platelet-activating factor and exogenous AA, there was a 4-fold increase in 5-LO activity as compared with incubations with only platelet-activating factor and AA. This indicates that 5-LO phosphorylation can be one factor determining cellular 5-LO activity.

Interaction of 5-lipoxygenase with cellular proteins

5-Lipoxygenase (5LO) plays a pivotal role in cellular leukotriene synthesis. To identify proteins interacting with human 5LO, we used a two-hybrid approach to screen a human lung cDNA library. From a total of 1.5 × 107 yeast transformants, nine independent clones representing three different proteins were isolated and found to specifically interact with 5LO. Four 1.7- to 1.8-kb clones represented a 16-kDa protein named coactosin-like protein for its significant homology with coactosin, a protein found to be associated with actin in Dictyostelium discoideum. Coactosin-like protein thus may provide a link between 5LO and the cytoskeleton. Two other yeast clones of 1.5 kb encoded transforming growth factor (TGF) type β receptor-I-associated protein 1 partial cDNA. TGF type β receptor-I-associated protein 1 recently has been reported to associate with the activated form of the TGF β receptor I and may be involved in the TGF β-induced up-regulation of 5LO expression and activity observed in HL-60 and Mono Mac 6 cells. Finally, three identical 2.1-kb clones contained the partial cDNA of a human protein with high homology to a hypothetical helicase K12H4.8 from Caenorhabditis elegans and consequently was named ΔK12H4.8 homologue. Analysis of the predicted amino acid sequence revealed the presence of a RNase III motif and a double-stranded RNA binding domain, indicative of a protein of nuclear origin. The identification of these 5LO-interacting proteins provides additional approaches to studies of the cellular functions of 5LO.

Survival in treated hypertension: follow up study after two decades
