Vanhustenhuolto + living lab = mahdollinen yhtälö?

Työ on laajaan dokumenttiaineistoon, haastatteluihin ja havaintoihin perustuva living lab - tyyppisen tuotekehitysprosessin yksityiskohtainen kuvaus. Hankehistoriallisessa tapaustutkimuksessa on käytetty historiantutkimuksen menetelmiä. Vanhustenkeskuksessa toteutetun living lab -hankkeen lopputuloksena syntyi vanhusten liikkeitä monitoroiva hoitotyön apuväline: turvalattia. Living lab -tyyppisessä tuotekehittämisessä on keskeistä teknologian kehittäminen tuotteen todellisessa käyttöympäristössä siten, että käyttäjät osallistuvat aktiivisesti kehitystyön kaikkiin vaiheisiin. Tutkimuksessa hankkeen etenemistä ja turvalattiateknologian rakentumista tarkastellaan toimijaverkostoteorian ja yhteisöllisen oppimisen käsitteen tarjoamista näkökulmista. Tutkimuksessa kiinnitetään erityisesti huomiota siihen, minkälaisia intressejä teknologian kehittämiseen osallistuvilla ryhmillä on ja minkälaisia konflikteja näiden intressien pohjalta syntyy. Lisäksi tarkastelun keskiössä on käyttäjien ja tuotekehittäjien välinen oppiminen, jonka mahdollistaminen ja edistäminen on living lab -kehittämisen päämäärä. Tutkimuksen keskeinen johtopäätös on, että käyttäjiltä saatu palaute on välttämätöntä käyttökelpoisen sosiaali- ja terveydenhuollon alan teknologian aikaansaamiseksi, ja turvalattian tapauksessa käyttäjäpalaute myös uudelleensuuntasi teknologisen järjestelmän innovaatioprosessia. Käyttäjien ja tuotekehittäjien yhteistyön myötä turvalattiaan kehitettiin joukko uusia toiminnallisuuksia ja käsitys tuotteen ydinominaisuuksista sekä hyötylupauksesta muuttuivat. Turvalattian tapaus osoittaa lisäksi yhteisöllisen oppimisen merkityksen innovaatioprosessissa sekä living lab -tyyppisen tuotekehittämisen potentiaalin näiden oppimisprosessien mahdollistajana ja kiihdyttäjänä. Tapaus myös valottaa sitä, kuinka monimutkainen toimintakenttä vanhustenhuolto on teknologian kehittämisen ja sen käyttöönoton näkökulmasta. Näyttäisi kuitenkin siltä, että living lab -metodologian avulla voidaan ylittää joitakin geronteknologian kehittämiseen ja myös käyttöönottoon liittyviä haasteita.

Selvitys käytäntölähtöisen innovaatioympäristötyökalun Fab Lab -konseptin soveltuvuudesta Etelä-Pohjanmaan innovaatioympäristön kehittämisen työvälineeksi

Tämän esiselvityshankkeen tavoitteena oli perehtyä Fab Lab -konseptiin ja selvittää ne reunaehdot, jotka määrittävät konseptin käyttökelpoisuutta Etelä-Pohjanmaalla ja suomalaisissa olosuhteissa yleisemmin. Etelä-Pohjanmaan voidaan olettaa olevan potentiaalinen konseptin hyödyntäjä, koska alueella on runsaasti sellaista maaseudun pienyrittäjyyttä, jonka on vaikea hyödyntää etäällä olevia teknologiapalveluja. Lisäksi arvioitiin konseptin mahdollisuudet yhdistää erilaisia innovaatiotoimijoita tavalla, joka voisi tukea Seinäjoki Science Park -yhteisön vuorovaikutusta ja täten toimia innovaatioita edistävänä kehitysalustana. Esiselvityksen tuloksena syntyi soveltuvuusanalyysi, jossa: a) Analysoitiin konseptin sisältö ja toiminnalliset reunaehdot. b) Arvioitiin konseptin suhde ja uutuusarvo alueen olemassa oleviin innovaatiopalveluihin ja toimijoihin. c) Arvioitiin konseptin mahdollisuudet toimia Seinäjoki Science Park -yhteisön vuorovaikutusta ja innovaatiotoimintaa edistävänä kehitysalustana. Soveltuvuusanalyysin pohjalta on tehty johtopäätökset Fab Lab -konseptin tarjoamista mahdollisuuksista suhteessa alueen innovaatioympäristön kehittämiseen, sekä suositukset mahdollisista jatkotoimista. Esiselvitys on toteutettu osana Seinäjoen seudun aluekeskusohjelmaa ja sen tilaajana on toiminut Seinäjoen Teknologiakeskus Oy.

Doing marriage and parenthood: The division of household labour across two life course events

The current study is a longitudinal investigation into changes in the division of household labour across transitions to marriage and parenthood in the UK. Previous research has noted a more traditional division of household labour, with women performing the majority of housework, amongst spouses and couples with children. However, the bulk of this work has been cross-sectional in nature. The few longitudinal studies that have been carried out have been rather ambiguous about the effect of marriage and parenthood on the division of housework. Theoretically, this study draws on gender construction theory. The key premise of this theory is that gender is something that is performed and created in interaction, and, as a result, something fluid and flexible rather than fixed and stable. The idea that couples ‘do gender’ through housework has been a major theoretical breakthrough. Gender-neutral explanations of the division of household labour, positing rational acting individuals, have failed to explicate why women continue to perform an unequal share of housework, regardless of socio-economic status. Contrastingly, gender construction theory situates gender as the key process in dividing household labour. By performing and avoiding certain housework chores, couples fulfill social norms of what it means to be a man and a woman although, given the emphasis on human agency in producing and contesting gender, couples are able to negotiate alternative gender roles which, in turn, feed back into the structure of social norms in an ever-changing societal landscape. This study adds extra depth to the doing gender approach by testing whether or not couples negotiate specific conjugal and parent roles in terms of the division of household labour. Both transitions hypothesise a more traditional division of household labour. Data comes from the British Household Panel Survey, a large, nationally representative quantitative survey that has been carried out annually since 1991. Here, data tracks the same 776 couples at two separate time points – 1996 and 2005. OLS regression is used to test whether or not transitions to marriage and parenthood have a significant impact on the division of household labour whilst controlling for host of relevant socio-economic factors. Results indicate that marriage has no significant effect on how couples partition housework. Those couples making the transition from cohabitation to marriage do not show significant changes in housework arrangements from those couples who remain cohabiting in both waves. On the other hand, becoming parents does lead to a more traditional division of household labour whilst controlling for socio-economic factors which accompany the move to parenthood. There is then some evidence that couples use the site of household labour to ‘do parenthood’ and generate identities which both use and inform socially prescribed notions of what it means to be a mother and a father. Support for socio-economic explanations of the division of household labour was mixed although it remains clear that they, alone, cannot explain how households divide housework.

Depression and Cognition in Type 2 Diabetes from a Life Course Perspective

Background: Type 2 diabetes is linked to several complications which add to both physical and mental distress. Depression is a common co-morbidity of diabetes which can occur both as a cause and a consequence of type 2 diabetes. Depression has been shown to correlate with glucose regulation and treating depression might prove beneficial for glucose regulation as well as for mental well being. Another complication which might affect diabetes management is cognitive decline. Several risk factors and complications of diabetes might modify the risk for developing cognitive impairment, which is increased 1.5 times among subjects with type 2 diabetes. Type 2 diabetes, depression and impaired cognitive performance have all been linked to low birth weight. This thesis aimed to explore the effects and interactions of birth weight, depression and cognitive ability in relation to type 2 diabetes from a life course perspective. Subjects and methods: Studies I, II and V were part of the Helsinki Birth Cohort Study. 2003 subjects participated in an extensive clinical examination at an average age of 61 years. A standard glucose tolerance test (OGTT) was performed and depressive symptoms were assessed using the Beck Depression Inventory (BDI). In addition data was obtained from child welfare clinics and national registers. A subset of the cohort (n=1247) also performed a test on cognitive performance (CogState ®) at the average age of 64. Studies III and IV were randomised clinical trials where mildly depressed diabetic subjects were treated with paroxetine or placebo and the effect on metabolic parameters and quality of life was assessed. The first trial included 14 women and lasted 10 weeks, while the second trial included 43 subjects, both men and women, and lasted 6 months. Results: Type 2 diabetes was positively associated with the occurrence of depressive symptoms. Among diabetic subjects 23.6% had depressive symptoms, compared to 16.7% of subjects with normal glucose tolerance (OR = 1.77, p<0.001). Formal mediation analysis revealed that cardiovascular disease (CVD) is likely to act as a mediator in the association. Furthermore, low birth weight was found to modify the association between type 2 diabetes, CVD and depression. The association between BDI score and having type 2 diabetes or CVD was twice as strong in the subgroup with low birth weight (≤ 2500g) compared with the group with birth weight > 2500g (p for interaction 0.058). In the six months long randomised clinical trial (study IV) paroxetine had a transient beneficial effect on glycosylated haemoglobin A1c (GHbA1c) and quality of life when compared to placebo after three months of treatment. In study V we found that subjects with known diabetes had a consistently poorer level of cognitive performance than subjects with normal glucose tolerance in most of the tested cognitive domains. This effect was further amplified among those born with a small birth weight (p for interaction 0.002). Conclusions: Type 2 diabetes is associated with a higher occurrence of depressive symptoms compared to subjects with normal glucose tolerance. This association is especially strong among subjects with CVD and those born with a low birth weight. Treating depressed diabetic subjects with paroxetine has no long term effect on glucose regulation. Physicians should be aware of depression as an important co-morbidity of type 2 diabetes. Both depression and the cognitive decline often seen among diabetic subjects are increased if the subject is born with a low birth weight. Physicians should recognise low birth weight as an additional risk factor and modifier of diabetic complications.

A course for teaching design research methodology

Design research informs and supports practice by developing knowledge to improve the chances of producing successful products.Training in design research has been poorly supported. Design research uses human and natural/technical sciences, embracing all facets of design; its methods and tools are adapted from both these traditions. However, design researchers are rarely trained in methods from both the traditions. Research in traditional sciences focuses primarily on understanding phenomena related to human, natural, or technical systems. Design research focuses on supporting improvement of such systems, using understanding as a necessary but not sufficient step, and it must embrace methods for both understanding reality and developing support for its improvement. A one-semester, postgraduate-level, credited course that has been offered since 2002, entitled Methodology for Design Research, is described that teaches a methodology for carrying out research into design. Its steps are to clarify research success; to understand relevant phenomena of design and how these influence success; to use this to envision design improvement and develop proposals for supporting improvement; to evaluate support for its influence on success; and, if unacceptable, to modify, support, or improve the understanding of success and its links to the phenomena of design. This paper highlights some major issues about the status of design research and describes how design research methodology addresses these. The teaching material, model of delivery, and evaluation of the course on methodology for design research are discussed.

Towards a green synthesis of LAB's: Effect of rare earth metal ions on the benzene alkylation with 1-dodecene over NaFAU-Y zeolites

Chemically modified microporous materials can be prepared as robust catalysts suitable for application in vapor phase processes such as Friedel-Crafts alkylation. In the present paper we have investigated the use of rare earth metal (Ce3+, La3+, RE3+, and Sm3+) exchanged Na-Y zeolites as catalysts for the alkylation of benzene with long chain linear 1-olefin; 1-dodecene. Thermodesorption studies of 2,6-dimethylpyridine adsorbed catalysts (in the temperature range 573 to 873 K) show that the rare earth zeolites are highly Bronsted acidic in nature. A perfect correlation between catalyst selectivity towards the desired product (2-phenyldodecane) and Bronsted acid sites amount has been observed. (c) 2006 Springer Science + Business Media, Inc.

Vanhustenhuolto + living lab = mahdollinen yhtälö? Tutkimus geronteknologisen järjestelmän tuotekehitysprosessista

Työ on laajaan dokumenttiaineistoon, haastatteluihin ja havaintoihin perustuva living lab - tyyppisen tuotekehitysprosessin yksityiskohtainen kuvaus. Hankehistoriallisessa tapaustutkimuksessa on käytetty historiantutkimuksen menetelmiä. Vanhustenkeskuksessa toteutetun living lab -hankkeen lopputuloksena syntyi vanhusten liikkeitä monitoroiva hoitotyön apuväline: turvalattia.

The complete primary structure of a unique mannose/glucose-specific lectin from field bean (Dolichos lab lab)

The complete amino acid sequence of two non identical subunits of the glucose/mannose-specific lectin from Dolichos lab lab (field bean) has been determined by sequential Edman analyses of the intact subunits and peptides derived by enzymatic and chemical cleavage. Peptides were purified by reverse phase high performance liquid chromatography and ion pair chromatography. The D. lab lab lectin is a glycoprotein having two polypeptide chains of 132 and 105 amino acid residues. The amino acid sequence of the D. Lab lab lectin is compared with the various lectins of the family Leguminosae. The D. lab lab lectin is the only species of the tribe Phaseoleae that contains two nonidentical subunits of almost equal size and that shows a specificity to glucose/ mannose. The lectin shows a greater homology to the glucose/mannose specific lectins, especially concanavalin A. The unique subunit architecture of the D. lab lab lectin indicates the presence of new post translational cleavage sites.
