Neural specialization to human faces at the age of 7 months.
2021
AbstractSensitivity to human faces has been suggested to be an early emerging capacity that promotes social interaction. However, the developmental processes that lead to cortical specialization to faces has remained unclear. The current study investigated both cortical sensitivity and categorical specificity through event-related potentials (ERPs) previously implicated in face processing in 7-month-old infants (N290) and adults (N170). Using a category-specific repetition/adaptation paradigm, cortical specificity to human faces, or control stimuli (cat faces), was operationalized as changes in ERP amplitude between conditions where a face probe was alternated with categorically similar or …
Functional connectivity of major depression disorder using ongoing EEG during music perception
2020
Abstract Objective The functional connectivity (FC) of major depression disorder (MDD) has not been well studied under naturalistic and continuous stimuli conditions. In this study, we investigated the frequency-specific FC of MDD patients exposed to conditions of music perception using ongoing electroencephalogram (EEG). Methods First, we applied the phase lag index (PLI) method to calculate the connectivity matrices and graph theory-based methods to measure the topology of brain networks across different frequency bands. Then, classification methods were adopted to identify the most discriminate frequency band for the diagnosis of MDD. Results During music perception, MDD patients exhibit…
Psychometric properties of 12-item self-administered World Health Organization disability assessment schedule 2.0 (WHODAS 2.0) among general populati…
2019
WHODAS 2.0 is a unified scale to measuring disability across diseases, countries, and cultures. The objective was to explore the available evidence on the psychometric properties of 12-item self-administered WHODAS 2.0 among a general population and people with non-acute physical causes of disability.Five databases Medline, Embase, Web of Science, Scopus, and PsycINFO were searched for papers related to the validity, reliability, responsiveness, minimal clinically important difference or minimal detectable change of 12-item self-administered WHODAS 2.0. In order to avoid missing any potentially relevant studies, the search clauses were left as generic as possible and the refining search was…
Heart Rate Dynamics after Combined Strength and Endurance Training in Middle-Aged Women: Heterogeneity of Responses
2013
The loss of complexity in physiological systems may be a dynamical biomarker of aging and disease. In this study the effects of combined strength and endurance training compared with those of endurance training or strength training alone on heart rate (HR) complexity and traditional HR variability indices were examined in middle-aged women. 90 previously untrained female volunteers between the age of 40 and 65 years completed a 21 week progressive training period of either strength training, endurance training or their combination, or served as controls. Continuous HR time series were obtained during supine rest and submaximal steady state exercise. The complexity of HR dynamics was assesse…
State of the Art Literature Review on Network Anomaly Detection
2018
As network attacks are evolving along with extreme growth in the amount of data that is present in networks, there is a significant need for faster and more effective anomaly detection methods. Even though current systems perform well when identifying known attacks, previously unknown attacks are still difficult to identify under occurrence. To emphasize, attacks that might have more than one ongoing attack vectors in one network at the same time, or also known as APT (Advanced Persistent Threat) attack, may be hardly notable since it masquerades itself as legitimate traffic. Furthermore, with the help of hiding functionality, this type of attack can even hide in a network for years. Additi…
A Novel Deep Learning Stack for APT Detection
2019
We present a novel Deep Learning (DL) stack for detecting Advanced Persistent threat (APT) attacks. This model is based on a theoretical approach where an APT is observed as a multi-vector multi-stage attack with a continuous strategic campaign. To capture these attacks, the entire network flow and particularly raw data must be used as an input for the detection process. By combining different types of tailored DL-methods, it is possible to capture certain types of anomalies and behaviour. Our method essentially breaks down a bigger problem into smaller tasks, tries to solve these sequentially and finally returns a conclusive result. This concept paper outlines, for example, the problems an…

Afrikkalaisesta nykytaiteesta kirjoittamisen haasteet. Näyttelyluetteloiden risteävät diskurssit
2015
Länsimaissa järjestetyt afrikkalaisen nykytaiteen näyttelyt ovat osoittautuneet monin tavoin ongelmalliseksi: purkavatko vai uusintavatko ne länsimaiden ja Afrikan välisiä koloniaalisia valtahierarkioita? Myös Suomessa on järjestetty viime vuosina useita laajoja nykytaiteen näyttelyitä, joissa Afrikkaa on lähestytty eri näkökulmista. Millaisia merkityksiä afrikkalainen nykytaide saa näiden näyttelyiden näyttelyjulkaisuissa? peerReviewed
Community-dwelling older adults and their informal carers call for more attention to psychosocial needs - Interview study on unmet care needs in thre…
2022
Background: Unmet care needs are usually defined in terms of receiving sufficient help in instrumental activities and activities of daily living. Research on unmet needs is mostly based on quantitative data. Older persons’ and informal carers’ views and experiences have received less attention. Methods: In this paper, we rely on a definition of unmet needs which includes both unmet needs due to insufficient care and those situations where informal carers experience undue strain. Using theory-driven content analysis, we examine community-dwelling older adults’ and their informal carers’ experiences of unmet needs: what kind of unmet needs they have, why and in which ways these needs are left…
Everyday life and the new shapes of identities : The different meanings of ‘things that did not happen’ in the lives of Finnish older persons during …
2021
The COVID-19 pandemic has affected our lives in many ways since the end of 2019. This paper investigates the everyday lives of Finnish older persons during the first three months of the pandemic when they were required to stay in “quarantine-like conditions.” The study utilises the ‘sociology of nothing’ in exploring the meanings of nothingness in the everyday lives of older people; that is, the things, events and people that were absent from their lives because of the pandemic. The main interest of the article is to reverse the typical analytical focus from ‘things that happened’ to ‘things that did not happen’ and to shed light on the experiences and descriptions of older persons' unlived…
