Tietämyksen jakaminen yrityksessä – motivaatio ja sosiaalinen media

2011

Rajala, Jussi Tietämyksen jakaminen yrityksessä – motivaatio ja sosiaalinen media Jyväskylä: Jyväskylän yliopisto, 2010, 22 s. Tietojärjestelmätiede, kanditaatintutkielma Ohjaaja: Seppänen, Ville Yksilöiden haluttomuus jakaa ja yhdistää tietämystään on yksi keskeisimmistä esteistä tietämyksen jakamisen esteistä. Erityisesti globaalisti toimivissa yrityksissä voidaan luoda merkittävä kilpailuetu saattamalla koko yrityksen tietämys kaikkien työntekijöiden käyttöön. Tutkimuksessa selvitetään sosiaalisen median mahdollisuuksia tehostaa tiedon jakamista. Tutkielmassa määritellään kirjallisuuden avulla mitä on yrityksessä jaettava tietämys ja selvitetään mitkä tekijät vaikuttavat työntekijän halu…

Yksikammioisten sydänlasten motorinen kehitys 16 ja 52 viikon iässä, vertaileva tutkimus

2009

Tausta: Suomessa syntyy vuosittain noin 20 lasta, joilla on vaikea-asteisimpiin sydänvikoihin kuuluva yksikammioinen sydän, hypoplastinen vasemman kammion oireyhtymä (HLHS) tai muu yksikammioinen sydänvika (UVH). Aikaisemmin nämä lapset menehtyivät pian syntymän jälkeen. Suomessa on alettu hoitaa näitä lapsia vuodesta 1995 Norwoodin ym. 1980 kehittämän kolmivaiheisen leikkausmenetelmän avulla, jonka ansiosta suurin osa näistä lapsista jää henkiin. Näiden lasten kokonaiskehitys ja etenkin motorinen kehitys on osoittautunut olevan jäljessä verrattuna terveisiin lapsiin. Tutkimuksia, joissa yksikammioisten sydänlasten varhaista motorista kehitystä on tarkemmin kuvattu ja analysoitu ei ole löyt…

Search for Electron Antineutrino Appearance in a Long-baseline Muon Antineutrino Beam

2020

Electron antineutrino appearance is measured by the T2K experiment in an accelerator-produced antineutrino beam, using additional neutrino beam operation to constrain parameters of the Pontecorvo-Maki-Nakagawa-Sakata (PMNS) mixing matrix. T2K observes 15 candidate electron antineutrino events with a background expectation of 9.3 events. Including information from the kinematic distribution of observed events, the hypothesis of no electron antineutrino appearance is disfavored with a significance of 2.40 σ and no discrepancy between data and PMNS predictions is found. A complementary analysis that introduces an additional free parameter which allows non-PMNS values of electron neutrino and a…

Impaired geometric properties of tibia in older women with hip fracture history.

2007

This study evaluated side-to-side differences in tibial mineral mass and geometry in women with previous hip fracture sustained on average 3.5 years earlier. Both tibial mineral mass and geometry were found to be reduced in the fractured leg. INTRODUCTION: The purpose of this study was to evaluate side-to-side differences in tibial mineral mass and geometry after hip fracture and to assess the determinants of such differences. METHODS: Thirty-eight 60- to 85-year-old women with a previous hip fracture and 22 same-aged control women without fractures participated in the study. Bone characteristics of the distal tibia and tibial shaft of both legs were assessed using pQCT in order to compare …

Beneficial Intervertebral Disc and Muscle Adaptations in High-Volume Road Cyclists

2019

PURPOSE: Cycling is widely practiced as a mode of transportation, a leisurely pursuit and a competitive sport. Approximately half of cyclists experience low back pain. Yet, there has been limited study of spine tissue adaptations due to cycling. METHODS: To investigate potential risk factors for spinal pain, we compared 18 high-volume cyclists (>150 km per week for ³5 years) to 18 height-matched non-sporting referents. Participants had no history of spinal pathology. Magnetic resonance imaging was used to quantify intervertebral disc (IVD) morphology and hydration; and psoas, erector spinae, quadratus lumborum and multifidus muscle size and fat content. Endurance of trunk muscles (flexors a…

Mechanical loading influences the lumbar intervertebral disc : A cross‐sectional study in 308 athletes and 71 controls

2021

There is evidence in animal populations that loading and exercise can positively impact the intervertebral disc (IVD). However, there is a paucity of information in humans. We examined the lumbar IVDs in 308 young athletes across six sporting groups (baseball, swimming, basketball, kendo, soccer and running; mean age 19yrs) and 71 non‐athletic controls. IVD status was quantified via the ratio of IVD to vertebral body height (IVD hypertrophy) and ratio of signal intensity in the nucleus to that in the annulus signal (IVD nucleus hydration) on sagittal T2‐weighted MRI. P‐values were adjusted via the false discovery rate method to mitigate false positives. In examining the whole collective, co…

Exercise for the intervertebral disc : a 6-month randomised controlled trial in chronic low back pain

2020

Background context Muscle, bone and tendon respond anabolically to mechanical forces. Whether the intervertebral disc (IVD) can benefit from exercise is unclear. Purpose To examine whether exercise can beneficially affect IVD characteristics. Study design/setting This is a single-blinded 6-month randomised controlled trial (ACTRN12615001270505) in an exercise and physiotherapy clinic. Patient sample Forty patients with chronic non-specific low back pain (NSCLBP) are included in this study. Outcome measures The primary outcome was lumbar IVD T2 time (MRI). Secondary outcomes included IVD diffusion coefficient and IVD expansion with short-duration lying. Methods Twenty patients progressively …

Characterization of Intervertebral Disc Changes in Asymptomatic Individuals with Distinct Physical Activity Histories Using Three Different Quantitat…

2020

(1) Background: Assessments of intervertebral disc (IVD) changes, and IVD tissue adaptations due to physical activity, for example, remains challenging. Newer magnetic resonance imaging techniques can quantify detailed features of the IVD, where T2-mapping and T2-weighted (T2w) and Dixon imaging are potential candidates. Yet, their relative utility has not been examined. The performances of these techniques were investigated to characterize IVD differences in asymptomatic individuals with distinct physical activity histories. (2) Methods: In total, 101 participants (54 women) aged 25&ndash
