    Abstract : I: Amplitude and phase relationship between alpha and beta oscillations in the human EEG We have studied the relation between two oscillatory patterns within EEG signals (oscillations with main frequency 10 Hz and 20 Hz), with wavelet-based methods. For better comparison, a variant of the continuous wavelet transform, was derived. READ MORE

  5. 5. Violence prevention and management in acute psychiatric care: aspects of nursing practice

    University dissertation from Stockholm : Karolinska Institutet, Dept of Clinical Neuroscience

    Author : Anna Björkdahl; Karolinska Institutet.; Karolinska Institutet.; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Aim: The general aim of this thesis was to explore and evaluate different aspects of nursing practice in relation to prediction, prevention and management of patient violence in acute psychiatric care. The specific aims were: to evaluate the short-term predictive capacity of the violence risk assessment instrument Brøset Violence Checklist (BVC) when used by nurses in a psychiatric intensive care unit (study I), to compare the occurrences of coercive interventions and violence-related staff injuries before and after a two-year nursing development and violence prevention intervention (study II), to describe aspects of the caring approaches used by nurses in acute psychiatric intensive care units (study III) and finally (in study IV) to test the hypothesis that staff training according to the ‘Bergen model’ has a significant positive influence on the violence prevention and management climate in psychiatric inpatient wards, as perceived by patients and staff.
