Understanding youth athletes' life designing processes through dream day narratives
2018
A number of studies have investigated career pathways in elite sport with retrospective designs, but few studies have explored how youth elite athletes construct narratives about their future lives and how their dreams and hopes relate to their careers in sport and other life contexts. We drew on career construction theory to understand youth elite athletes' dreams for the future and prominent life themes. Seventeen Finnish youth elite athletes (7 men, 10 women) in the first year of upper secondary sport school participated in the study. They were asked to make visual representations of their “dream days”, and these were used as aids for reflection in low-structured interviews where partici…
Ecosystem Architecture Management in the Public Sector : From Problems to Solutions
2019
Based on our research concerning enterprise architecture (EA) in the Finnish public sector, we discuss how EA concept and tool need to be developed to support government business ecosystem and organization design. Our research context indicates, beyond a federal government or a state one, that even a single municipality, like a city concern, can be perceived as an ecosystem of its sectoral domains, subsidiaries and such. We outline a vision of an overall ontology-based, shared EA repository for the-whole-of-government current state descriptions and specify the central design principles and functional requirements for such a system, illustrating some potential use cases of it. Based on inter…
A Smartphone App to Promote Healthy Weight Gain, Diet, and Physical Activity During Pregnancy (HealthyMoms): Protocol for a Randomized Controlled Tri…
2019
BACKGROUND: Excessive gestational weight gain is common and associated with adverse outcomes both in the short and long term. Although traditional lifestyle-based interventions have shown to mitigate excess gestational weight gain, little is known about whether mobile Health (mHealth) apps can promote healthy weight gain, diet, and physical activity during pregnancy. OBJECTIVE: The primary aim of the HealthyMoms trial is to determine the effectiveness of a smartphone app (HealthyMoms) for mitigating excess gestational weight gain during pregnancy. Secondary aims are to determine the effectiveness of the app on dietary habits, physical activity, body fatness, and glycemia during pregnancy. M…
Influence of Vertical Dimension of Occlusion on Peak Force During Handgrip Tests in Athletes
2018
Background: In contact sports, such as martial arts, protection from oral injuries is generally recommended. Several authors have focused on the effects of wearing such oral protective gear on sports performances and, in particular, occlusal devices. Although many studies have shown improvements in athletic performance, especially in maximal isometric strength, to date there is still no consensus on the issue. Objectives: The aim of our study was to evaluate differences in isometric handgrip before and after the application of an occlusal splint (OS) in martial arts athletes. Methods: A repeated measures within-subjects design was adopted for the study. Twenty-five young martial arts athlet…
A Statistical Model of Spine Shape and Material for Population-Oriented Biomechanical Simulation
2021
In population-oriented ergonomics product design and musculoskeletal kinetics analysis, digital spine models of different shape, pose and material property are in great demand. The purpose of this study was to construct a parameterized finite element spine model with adjustable spine shape and material property. We used statistical shape model approach to learn inter-subject shape variations from 65 CT images of training subjects. Second order polynomial regression was used to model the age-dependent changes in vertebral material property derived from spatially aligned CT images. Finally, a parametric spine generator was developed to create finite element instances of different shapes and m…
Making and breaking relationships on social media: the impacts of brand and influencer betrayals
2021
This study considers how the relationships between social media influencers, brands and individuals are intertwined on social media and analyses the spill-over effects of feelings of betrayal. An experimental design with two transgression scenarios (influencer vs. brand) was created, and 250 individuals were recruited to participate in the study. The results show that a perceived betrayal by a brand can negatively affect the perceived coolness of the social media influencer that has endorsed the brand, as well as the parasocial relationships that followers have with the influencer. Accordingly, a perceived betrayal by a social media influencer can negatively affect attitudes, trust and purc…
Ketterä projektinhallinta PMBOK:in ja CMMI:n näkökulmasta
2010
Plattonen, Noora Ketterä projektin hallinta PMBOK:in ja CMMI:n näkökulmasta / Noora Plattonen Jyväskylä: Jyväskylän yliopisto, 2010. 58 s. Tutkielma Tässä tutkielmassa tarkastellaan ketterän lähestymistavan mukaista projektinhallintaa perinteisen projektinhallinnan prosessien näkökulmasta. Tarkastelun viitekehyksiksi on valittu PMBOK (Project Management Body of Knowledge) ja CMMI (Capability Maturity Model Integration). Tavoitteena on kartoittaa perinteisen ja ketterän lähestymistavan mukaisen projektinhallinnan eroja ja yhtäläisyyksiä sekä miten näitä lähestymistapoja voidaan yhdistellä. Tutkimus on suoritettu kirjallisuuteen pohjalta kokoamalla yhteen aiemmissa kartoituksissa löytyneitä e…
Ketterien kehitysmenetelmien käsitys projektinhallinnasta: esimerkkinä Scrum
2009
Luomala, Joni Petteri Ketterien kehitysmenetelmien käsitys projektinhallinnasta: esimerkkinä Scrum / Luomala Joni Petteri Jyväskylä: Jyväskylän yliopisto, 2009. 31 s. Kandidaatintutkielma Yhä useammat ohjelmistojenkehitysprojektit toteutetaan käyttäen perinteisten suunnittelulähtöisten menetelmien sijasta ketteriä menetelmiä. Ketterät menetelmät ovat asiakaslähtöisiä menetelmiä, joissa asiakas on tiiviisti mukana järjestelmän kehittämisessä. Ketterille menetelmille on ominaista toimivan ohjelman tuottaminen lyhyissä tuotantosykleissä, joiden jälkeen esitetään asiakkaalle aikaansaannokset ja asiakas pääsee esittämään kommentteja syntyvästä järjestelmästä ja sen vastaavuudesta vaatimuksiin.…
Integrating risk management tools for regional forest planning : an interactive multiobjective value at risk approach
2018
In this paper, we present an approach employing multiobjective optimization to support decision making in forest management planning under risk. The primary objectives are biodiversity and timber cash flow, evaluated from two perspectives: the expected value and the value-at-risk (VaR). In addition, the risk level for both the timber cash flow and biodiversity values are included as objectives. With our approach, we highlight the trade-off between the expected value and the VaR, as well as between the VaRs of the two objectives of interest. We employ an interactive method in which a decision maker iteratively provides preference information to find the most preferred management plan and lea…
Flexible Data Driven Inventory Management with Interactive Multiobjective Lot Size Optimization
2021
We study data-driven decision support and formalise a path from data to decision making. We focus on lot sizing in inventory management with stochastic demand and propose an interactive multi-objective optimisation approach. We forecast demand with a Bayesian model, which is based on sales data. After identifying relevant objectives relying on the demand model, we formulate an optimisation problem to determine lot sizes for multiple future time periods. Our approach combines different interactive multi-objective optimisation methods for finding the best balance among the objectives. For that, a decision maker with substance knowledge directs the solution process with one’s preference inform…
