Aikuisten ja projekti-organisaation oppiminen järjestelmä- ja toimintatapojen kehitysprojektissa

Tutkimuksen tarkoituksena on selvittää miten ja mitä tieto- ja viestintä teknologiaorganisaatio (=ICT –organisaatio) oppii järjestelmien ja toimintatapojen kehitysprojektissa. Tutkimuksen tavoitteena on saada tietoa miten kehitysprojektiin osallistuneet henkilöt ovat kokeneet projektin ensimmäisen vaiheen vaikuttaneen omaan ja organisaation oppimiseen. Samalla halutaan selvittää missä on onnistuttu ja mitä olisi voinut tehdä toisin. Aiheesta ei löytynyt täysin vastaavia aikaisempia tutkimuksia. Tutkimus on luonteeltaan laadullinen. Aineisto kerättiin haastattelemalla kuutta järjestelmien ja toimintatapojen kehitysprojektiin osallistunutta henkilöä. Haastattelut toteutettiin yksilöhaastatteluina teemahaastattelua apuna käyttäen. Tutkimuksen teoriaosassa käsiteltiin aikuisten oppimista, organisaation oppimista ja kerrottiin muutamista samantyyppisistä järjestelmä- ja toimintatapojen kehitysprojekteista. Tutkimuksessa tuli esiin, että aikuiset oppivat parhaiten ryhmässä. Aikaisempi tieto ja kokemus, hyvä ilmapiiri, motivaatio ja sitoutuminen edistävät oppimista. Kiire, ongelmat tiedonkulussa ja epäselvät roolit ja vastuut organisaatiossa koettiin oppimisen esteiksi. Projektin onnistumisina koettiin myönteinen ilmapiiri ja se, että on oppinut uutta muilta projektin jäseniltä. Projektin kehityskohteissa tuli esille suunnitelmallisuuden puute, tavoiteaikataulun venyminen ja kuten myös oppimisen esteissä, ongelmat tiedonkulussa ja epäselvyydet rooleissa ja vastuissa. Tutkimuksen tulosten perusteella aikuisten ja organisaation oppimisen ja projektin onnistumisen avaimet ovat: hyvä suunnittelu, hyvä ilmapiiri, motivaatio, sitoutuminen, ryhmässä oppiminen, selkeät roolit ja vastuut, hallittu tiedonjakaminen, hallittu ajankäyttö. Tutkimuksen tuloksissa korostuivat erityisesti tiedonkulun, aikataulutuksen ja epäselvien roolien ja vastuiden vaikutus oppimiseen ja projektin onnistumiseen. Sitä olisi mielenkiintoista tutkia vielä lisää.

Achieving the millennium development goals for health - Time to reassess strategies for improving health in developing countries

Making best use of resources is vital in developing countries that are struggling to improve public health with limited funds. The WHO-CHOICE project has developed standardised methods to,evaluate the efficiency of a broad range of interventions. Ibis series starts by assessing die problems with strategies for meeting the millennium development goals. Subsequent articles describe the methods, apply them to maternal and neonatal health, child health, HIV and AIDS, tuberculosis, and malaria, and consider the implications for an overall health strategy. All appear on bmj.com this week.

Asymptomatic primary Epstein-Barr virus infection occurs in the absence of blood T-cell repertoire perturbations despite high levels of systemic viral load

Primary infection with the human herpesvirus, Epstein-Barr virus (EBV), may result in subclinical seroconversion or may appear as infectious mononucleosis (IM), a lymphoproliferative disease of variable severity. Why primary infection manifests differently between patients is unknown, and, given the difficulties in identifying donors undergoing silent seroconversion, little information has been reported. However, a longstanding assumption has been held that IM represents an exaggerated form of the virologic and immunologic events of asymptomatic infection. T-cell receptor (TCR) repertoires of a unique cohort of subclinically infected patients undergoing silent infection were studied, and the results highlight a fundamental difference between the 2 forms of infection. In contrast to the massive T-cell expansions mobilized during the acute symptomatic phase of IM, asymptomatic donors largely maintain homeostatic T-cell control and peripheral blood repertoire diversity. This disparity cannot simply be linked to severity or spread of the infection because high levels of EBV DNA were found in the blood from both types of acute infection. The results suggest that large expansions of T cells within the blood during IM may not always be associated with the control of primary EBV infection and that they may represent an overreaction that exacerbates disease.

Cytotoxic T cell polyepitope vaccines delivered by ISCOMs

CD8 alpha beta cytotoxic T lymphocyte (CTL) polyepitope or polytope vaccines have traditionally been delivered using recombinant vector or DNA based delivery modalities. Here we show the delivery of polytope vaccines in the form of either synthetic polypeptides or recombinant polytope proteins by ImmunoStimulatory COMplexes (ISCOMs (R)). Induction of multiple protective CTL responses by these polytope-ISCOM formulations were comparable to viral vector or DNA based delivery modalities as assessed by IFN gamma ELISpot, chromium release and viral challenge assays. Measurement of CTL responses specific for the different epitopes revealed imunodominance patterns, which were largely independent of the vaccine vector or the order of the epitopes in the polytope. ISCOMs thus emerge as a viable human delivery modality for protein-based polytope vaccines. (C) 2001 Elsevier Science Ltd. All rights reserved.

The effects of fillers on the chemorheology of highly filled epoxy resins: I. Effects on cure transitions and kinetics

This work examines the effects of level of silica filler (at 0, 10, 30, 50wt%) on the gelation and vitrification of a model silica-filled diglycidyl ether of bisphenol F (DGEBF)/methylenedianiline (MDA) system. An increased filler level is shown to decrease the gelation and vitrification times at low temperatures (below 80degreesC). FTIR cure kinetics show that the reaction rates are increased and the activation energies of gelation are reduced at these temperatures, indicating that network formation is made easier. Entropic and catalytic reasons for this phenomenon are discussed. (C) 2003 Society of Chemical Industry.

Nó do Barreiro: ligação da terceira travessia do Tejo à ER11-2 articulação com a rede envolvente, traçado (estudo prévio)

O objectivo deste projecto foi desenvolver, a nível de Estudo Prévio, a solução mais adequada em termos de traçado rodoviário para o Nó do Barreiro, partindo dos pressupostos do Estudo de Viabilidade (Outubro 2006) e do Estudo Prévio (Maio 2008) existentes. Os estudos referidos foram realizados no âmbito da Terceira Travessia do Tejo, tendo sido incluídas as acessibilidades rodoviárias que contêm o Nó do Barreiro que será alvo de análise. Este Nó de Ligação visa garantir a melhor articulação entre as duas vias rápidas previstas (IC21 e ER 11-2) e as acessibilidades locais da cidade do Barreiro. O projecto que se apresenta foi elaborado com base no software InRoads para o cálculo rodoviário e na plataforma de desenho AutoCAD para a produção das peças desenhadas. Os traçados e os cálculos respectivos foram desenvolvidos sobre a cartografia do Estudo Prévio, à escala 1:5000, sendo os desenhos relativos ao traçado em Planta e Perfil Longitudinal apresentados na escala 1:2000. O volume de solos associados às terraplanagens do conjunto de ligações é apresentado em anexo e representa um total de 1.021.000m3, correspondendo 82% a material para aterro e 18% a escavação. Daqui se conclui que o nó apresenta um deficit de terras da ordem dos 653.000m3. De qualquer modo esta análise volumétrica não se deve dissociar do resto do empreendimento, para uma rigorosa e real avaliação do equilíbrio de terras. A nível da drenagem foram efectuados os cálculos hidrológicos, relativos à drenagem transversal das várias vias, sendo as mesmas representadas nos desenhos de Planta e Perfil Longitudinal na escala 1:2000.

Optimization of the Sybr Green real time PCR for the detection of Human Herpes Virus type 6 (HHV-6)

HHV-6 is the etiological agent of Exanthem subitum which is considered the sixth most frequent disease in infancy. In immuno-compromised hosts, reactivation of latent HHV-6 infection may cause severe acute disease. We developed a Sybr Green Real Time PCR for HHV-6 and compared the results with nested conventional PCR. A 214 pb PCR derived fragment was cloned using pGEM-T easy from Promega system. Subsequently, serial dilutions were made in a pool of negative leucocytes from 10-6 ng/µL (equivalent to 2465.8 molecules/µL) to 10-9 (equivalent to 2.46 molecules/µL). Dilutions of the plasmid were amplified by Sybr Green Real Time PCR, using primers HHV3 (5' TTG TGC GGG TCC GTT CCC ATC ATA 3)'and HHV4 (5' TCG GGA TAG AAA AAC CTA ATC CCT 3') and by conventional nested PCR using primers HHV1 (outer): 5'CAA TGC TTT TCT AGC CGC CTC TTC 3'; HHV2 (outer): 5' ACA TCT ATA ATT TTA GAC GAT CCC 3'; HHV3 (inner) and HHV4 (inner) 3'. The detection threshold was determined by plasmid serial dilutions. Threshold for Sybr Green real time PCR was 24.6 molecules/µL and for the nested PCR was 2.46 molecules/µL. We chose the Real Time PCR for diagnosing and quantifying HHV-6 DNA from samples using the new Sybr Green chemistry due to its sensitivity and lower risk of contamination.
