Tietojärjestelmien integraatioprojektien kriittiset menestystekijät

2018

Ajan kuluessa ja digitaalisen liiketoiminnan määrän kasvun kiihdyttämänä organisaatioiden sovellus- ja järjestelmäportfoliot ovat kasvaneet entistä laajemmiksi ja niistä on tullut entistä kriittisempiä liiketoiminnalle. Kun aiemmin lähes kaikki hoitui yhdellä toiminnanohjausjärjestelmällä, niin nyt niiden rinnalle on tullut erilaisia mikropalveluita ja räätälöityjä sovelluksia. Tämän seurauksena yrityksen data on hajautunut näiden järjestelmien välille ja tämän datan hallinnasta ja hyödyntämisestä on tullut entistä työläämpää. Tämä on lisännyt manuaalisen työn määrää sekä tehnyt liiketoimintaprosesseista raskaita. Prosesseja ja tietovirtoja on kuitenkin lähdetty automatisoimaan integraatioi…

Kieli-ideologioiden teoriaa ja käytäntöä

2012

Artikkelissa tarkastellaan kieli-ideologioiden tutkimusta ja sen teoreettis-metodisia ulottuvuuksia. Kieli-ideologian käsitettä on hyödynnetty erityisesti tutkittaessa, millaisia uskomuksia, arvostuksia, luokitteluja ja neuvotteluja kysymykset kielestä ja kielenkäytöstä herättävät. Artikkeli esittelee erilaisia tutkimusalalla käytettyjä käsitteitä ja keskeisiä tutkimusteemoja ja -kysymyksiä. Lisäksi pohditaan kieli-ideologioiden tutkimuksen ajankohtaisuutta Suomen näkökulmasta. Artikkelissa kuvataan erilaisia tapoja määritellä ja käyttää kieli-ideologian käsitettä eri tutkimuskonteksteissa. Esiin otetaan esimerkiksi ikonisaation, kertautuvuuden ja poistamisen semioottiset prosessit. Huomiot…

Ensemble deep clustering analysis for time window determination of event-related potentials

2023

Objective Cluster analysis of spatio-temporal event-related potential (ERP) data is a promising tool for exploring the measurement time window of ERPs. However, even after preprocessing, the remaining noise can result in uncertain cluster maps followed by unreliable time windows while clustering via conventional clustering methods. Methods We designed an ensemble deep clustering pipeline to determine a reliable time window for the ERP of interest from temporal concatenated grand average ERP data. The proposed pipeline includes semi-supervised deep clustering methods initialized by consensus clustering and unsupervised deep clustering methods with end-to-end architectures. Ensemble clusterin…

ProcMiner: Advancing Process Analysis and Management

2007

This paper contributes both to research and practice on process mining. Previous research on process mining has focused on mining patterns from event log files to generate process models. The process mining approach adopted in this paper is focused on producing patterns about process models, not the models themselves. The approach is demonstrated by ProcMiner -an explorative research prototype for management, consolidating, publishing, retrieving, and analyzing process models. Content-based document clustering is applied to process models represented as XML database in order to find topical groups from models. In practice, organizations face numerous challenges in managing their process mod…

Task-oriented reading efficiency : interplay of general cognitive ability, task demands, strategies and reading fluency

2022

AbstractThe associations among readers’ cognitive skills (general cognitive ability, reading skills, and attentional functioning), task demands (easy versus difficult questions), and process measures (total fixation time on relevant and irrelevant paragraphs) was investigated to explain task-oriented reading accuracy and efficiency (number of scores in a given time unit). Structural equation modeling was applied to a large dataset collected with sixth-grade students, which included samples of dysfluent readers and those with attention difficulties. The results are in line with previous findings regarding the dominant role of general cognitive ability in the accuracy of task-oriented reading…

Relationship between cognitive performance and mobility over the life course

2018

We studied cross-sectional, longitudinal and temporal associations between executive function and life-space mobility in old age. We assessed the association between intellectual ability in early adulthood and physical functioning in old age, and the association between early life motor development and cognitive performance in early old age. The participants of the first dataset were 157 persons aged 76-91 y who were followed up for two years as part of the Life-Space Mobility in Old Age study, and who took part in measurements on executive function (EF) implemented with the Trail Making Test and Life-Space Assessment. The second dataset comprised persons from the Helsinki Birth Cohort Stud…

Cognition in Interaction : Challenges in Assessing Persons with Sensory and Multiple disabilities

2021

This article reports a qualitative study of cognitive assessments of three teenagers with sensory and multiple disabilities, including moderate to profound developmental disability. The aim was to evaluate the possibilities for adapting standardized tests and the implementation of interactional partnership in assessment. Cognitive assessments were made with an individually-adapted psychological assessment tool, the Bayley Scales of Infant and Toddler Development. The assessment situations were video-recorded and analyzed based on sociocultural theories of early interaction, dynamic assessment, and the bodily-tactile modality of cognition. The results showed that the requirements for assessm…

Affective Mimetics, Emotional Information Space, and Metaverse

2021

Current technology design pursues applying human-like features to AI technologies. These attempts have faced many challenges due to the essential complexities of the human mind. Cognitive mimetics is a design approach to mimic human information processes in designing intelligent technologies. The focus is on mimicking cognition, human knowledge structures, and represented mental information contents which addresses a fundamental issue in technology design. However, cognition is one aspect of information processing in the human mind. Affective information processing also plays an essential role in addressing the meaningfulness of cognitive processes. This paper discusses affective mimetics (…
