A new species of Capparis (Capparaceae) from ultramafic substrata in New Caledonia
2017
A new species of Capparis, C. parvifolia, is described and illustrated from New Caledonia, where it is known from a few localities on Mont Kaala on ultramafic substrata. The new species is characterized by the relatively small, linear leaf-blade and by the small size of the sepals, petals, stamens, gynophore and fruit. Its affinities with related taxa are discussed and its conservation status assessed.
2017
Diversification in flower shape and function is triggered by the high plasticity of flower meristems. Minute changes in space and time can profoundly affect the formation of adult structures. Dipsacoideae provides an excellent model system to investigate the evolutionary aspects of temporal and spatial changes in flower development due to its small size, the resolved phylogenetic framework, and significant diversity of perianth form and merosity. In the present study, we investigated the sequence of floral organ initiation and quantified the interactions between flower meristem expansion and petal primordium size in eight species representing two major clades of Dipsacoideae. Our quantitati…
Helianthemum scopulicolum (Cistaceae), a new species from Majorca (Balearic Islands, Spain)
1999
Rupicolous plants coming from a single Balearic locality are described as a new species, Helianthemum scopulicolum. The plant is diploid (2n=20) and belongs to Helianthemum subgenus Helianthemum sect. Helianthemum. On morphological grounds, Helianthemum scopulicolum is related to some members of the H. apenninum aggregate, notably H. apenninum s.l., H. asperum and H. violaceum. However, the new species can be distinguished on the basis of leaves green, shining, glabrescent on the adaxial surface, deciduous short bracts, glabrescent inner sepals lacking long setae and pink-purple flowers.

The sensitivity of buckwheat plants to pathogens under conditions of mixed viral and mycoplasmal infection
2016
It was investigated, that mixed infection of buckwheat distributed in various ecological regions of Ukraine, the pathogens that belong to different taxonomic groups have different and peculiar morphological and structural properties. First was shown that buckwheat is affected by buckwheat burn virus (BBV) together with Mycoplasma. Mixed infection leads to proliferation of sepals, clarification of the flowers petals, reduction and greening of petals, hypoplasia or hypodevelopment of stamens and pistils: all of this can lead to partial or complete sterility.
Flower ontogeny inCapparis spinosa(Capparaceae) with special emphasis on symmetry expression
2015
The flower ontogeny of Capparis spinosa L. was studied using scanning electron microscopy (SEM) in order to shed light on the early expression of symmetry in a representative member of Capparaceae. Sepals start decussately with the abaxial and adaxial sepals, followed by the lateral ones. Petal appearance proceeds uni-directionally from the abaxial to the adaxial side. Stamens develop centrifugally on an androecial ring. Five to seven carpel lobes arise on a gynoecial ring. Monosymmetry is established in early development by the uni-directional petal appearance and is further enhanced by the acquisition of an abaxial nectary appendage and differential development of perianth organs at anthe…
Acceptance of Online Health Services for Self-Help in the Context of Mental Health : Understanding Young Adults Experiences
2018
This paper explores the understanding of the acceptance of online health services from a selfhelp perspective in the context of mental health. By examining the experiences of young adults, this paper develops a framework to leverage the current understanding of the factors that would support the acceptance and use of these types of services. To this end, a multidisciplinary perspective incorporating knowledge from the service marketing, health, and information systems literature is used. The results suggest that the production of online services that are meant for self-help purposes necessitates a focus on the acceptance of technology and, more importantly, instrumental value creation, as t…
Regular physical exercise before entering military service may protect young adult men from fatigue fractures
2019
Background Bone stress fractures are overuse injuries commonly encountered in sports and military medicine. Some fatigue fractures lead to morbidity and loss of active, physically-demanding training days. We evaluated the incidence, anatomical location, risk factors, and preventive measures for fatigue fractures in young Finnish male conscripts. Methods Five cohorts of 1000 men performing military service, classified according to birth year (1969, 1974, 1979, 1984, 1989), were analysed. Each conscript was followed for his full military service period (180 days for conscripts with rank and file duties, 270 days for those with special training, 362 days for officers and highly trained conscri…
Incorporating digital self-services into integrated mental health care:a physician’s perspective
2018
PurposeThis paper aims to enhance the current understanding of digital self-services (computerized cognitive behavioral therapy [cCBT]) and how they could be better incorporated into integrated mental health care from the physician’s perspective. Service marketing and information systems literature are combined in the context of mental health-care delivery.Design/methodology/approachAn online survey of 412 Finnish physicians was undertaken to understand physicians’ acceptance of cCBT. The study applies thematic analysis and structural equation modeling to answer its research questions.FindingsAdopting a service marketing perspective helps understand how digital self-services can be incorpor…
Teknologiaperustaisen itsepalvelun vaikutus palvelukokemukseen
2016
Teknologiaperustainen itsepalvelu on yleistynyt nopeasti ja se on joissakin tapauksissa korvaamassa kokonaan henkilökohtaisen palvelun. Yritysten kannalta olisi edullista, että mahdollisimman moni asiakas käyttäisi itsepalvelukanavia, mutta asiakkaat ovat usein tyytymättömiä tai turhautuneita itsepalveluun. Tässä kandidaatintutkielmassa selvitetään kirjallisuuskatsauksen keinoin, mitkä ulkoiset ja teknologialähtöiset tekijät vaikuttavat asiakkaan palvelukokemukseen teknologiaperustaisen itsepalvelun kontekstissa. Lisäksi tutkielmassa syvennytään tarkemmin ihmiskontaktin puuttumiseen palvelutapahtumasta, sekä siitä mahdollisesti seuraaviin haasteisiin onnistuneen palvelukokemuksen kannalta. …
