Has the Push for Equal Gender Representation Changed the Role of Women on German Supervisory Boards?
2017
In Germany, an intensive public debate about increasing female participation in leadership positions started in 2009 and proceeded until the beginning of 2015, when the German parliament enacted a board gender quota. In that period, the share of women on supervisory boards for 111 German publicly listed and fully codetermined companies (i.e. those which are affected by the quota law) more than doubled from 10.6 percent in 2009 to 22.6 percent in 2015. In 2016, the first year when the law was effective, the female share increased again by 4.5 percentage points. Using a hand-collected dataset, we investigate whether the rise in female board representation was accompanied by a change in gender…
Hybridization between mouse lemurs in an ecological transition zone in southern Madagascar
2009
Hybrid zones in ecotones can be useful model systems for the study of evolutionary processes that shape the distribution and discreteness of species. Such studies could be important for an improved understanding of the complex biogeography of Madagascar, which is renowned for its outstanding degree of small-scale endemism. Certain forest remnants in central Madagascar indicate that transitional corridors across the island could have connected microendemics in different forest types in the past. Evolutionary processes in such corridors are difficult to study because most of these corridors have disappeared due to deforestation in central Madagascar. We studied a hybrid zone in one of the few…
Discrepant partitioning of genetic diversity in mouse lemurs and dwarf lemurs--biological reality or taxonomic bias?
2013
Unequal degrees of taxonomic subdivision can pose problems for research that relies on cross-taxon comparisons of biogeographic patterns. Numerous species of lemurs have been described in recent years. These descriptions were unevenly distributed over the genera of lemurs as exemplified by the closely related mouse lemurs (Microcebus spp.) and dwarf lemurs (Cheirogaleus spp.). According to previous studies, these genera display striking differences such as many versus few species, small versus large distributions, and small versus large mitochondrial divergence within and between species. We questioned if these differences reflect the biological reality or a biased taxonomic subdivision, wh…
Range Shifts of Mouse Lemurs in South-Eastern Madagascar: Evidence from Mitochondrial Genetic Data
2012
The gray mouse lemur, Microcebus murinus, occurs mainly in dry forests in western Madagascar, but its distribution extends into humid littoral forests in the south-eastern Anosy Region. We sequenced the mitochondrial hypervariable region 1 for 282 M. murinus individuals from 13 south-eastern study sites. The spatial distribution of mitochondrial haplotypes and the varying genetic distances within two haplotype clades indicated a trend of decreasing genetic diversity towards the south-eastern margin of the range. Rufous mouse lemurs, Microcebus cf. rufus, have a complementary distribution in south-eastern Madagascar which does not overlap with that of M. murinus. Taken together, the spatial …
Population Genetics, Parasitism, and Long-Term Population Dynamics of Microcebus murinus in Littoral Forest Fragments of South-Eastern Madagascar
2012
Habitat fragmentation is a major threat for lemur conservation, as it reduces population sizes to levels that are nonviable in the long term. Alternatively, isolated populations may have great importance for conservation, as some are well protected and some lemurs do well even in small areas. Hence, knowing which characteristics indicate a population under threat is of paramount importance for conservation action. We studied Microcebus murinus populations confined to forest fragments of different sizes and states of degradation in south-eastern Madagascar to investigate relationships between population size, population dynamics, genetic diversity of coding and noncoding DNA, and infection r…
Microsatellite markers for paternity testing in fork-marked lemurs (Phaner furcifer)
2003
We report the development of three new microsatellites and four transferred across-species for fork-marked lemurs ( Phaner furcifer ). Two markers were isolated from Cheirogaleus medius and one from Microcebus murinus . The transferred markers also originate from Cheirogaleus medius and Microcebus murinus . The seven markers were tested on 30 individuals of Phaner furcifer and have proven to be useful for inclusion and exclusion of potential parents. The markers presented here are the first published for application on Phaner furcifer .

Kotona asuvan muistisairaan henkilön ja hänen läheistensä teknologiaan liittyvät tarpeet ja toiveet
2018
Tutkimuksessa selvitettiin millaisia tarpeita ja toiveita kotona asuvilla muistisairailla ja heidän läheisillään on kotona asumista tukevaan teknologiaan liittyen. Tutkimukseen osallistui 25 kotona asuvaa muistisairasta henkilöä ja 25 heidän läheistään. Metodina käytettiin etnografista tutkimusotetta. Aineistonkeruumenetelminäolivat avoin haastattelua ja havainnointi. Analyysimenetelmänä käytettiin sisällön analyysiä. Tarpeet ja toiveet voitiin luokitella kolmeen pääluokkaan, jotka olivat itsemääräämisoikeuden säilyminen, sosiaalisten suhteiden säilyminen ja liikkumisen oikeus ja turvallisuus. Haasteita olivat yksinäisyyden kokemus, muistin ja toimintakyvyn heikkenemiseen liittyvät ongelmat…
Association between urinary incontinence and frailty: a systematic review and meta-analysis
2018
Purpose: Urinary incontinence (UI) and frailty are common geriatric syndromes. Although literature increasingly supports a relationship between these two conditions, no systematic review and meta-analysis has been performed on this topic. Therefore, we aimed to investigate the potential association between UI and frailty, through a meta-analytic approach. Methods: A systematic search in major databases was undertaken until 15th March 2018 for studies reporting the association between UI and frailty. The prevalence of UI in people with frailty (vs. those without) was pooled through an odds ratio (OR) and 95% confidence intervals (CIs), with a random-effects model. The other outcomes were sum…
The effectiveness of a coordinated preventive care approach for healthy ageing (UHCE) among older persons in five European cities: A pre-post control…
2018
Abstract Background Older persons often have multiple health and social problems and need a variety of health services. A coordinated preventive approach that integrates the provision of health and social care services could promote healthy ageing. Such an approach can be organised differently, depending on the availability and organizational structures in the local context. Therefore, it is important to evaluate the effectiveness of a coordinated preventive care approach in various European settings. Objectives This study explored the effects of a coordinated preventive health and social care approach on the lifestyle, health and quality of life of community-dwelling older persons in five …
