How Good Is the Professional\u27s Aptitude in the Conceptual Understanding of Change Management?

As information technology (IT) functions and their professionals become partners in managing the information resource of the organization, contributors to the strategic planning process and major players in the business, rather than appendages which can be outsourced, new skills and competencies are needed for IT personnel. In particular, the proposition that IT specialists will have to function more like change agents has been echoed by a number of writers. However, there has been no prior empirical research that explicitly measures the degree of knowledge that IT specialists possess about fundamental concepts in the management of change in organizations. The present study offers to fill that gap. Data were collected using a survey instrument, the Managing Change Questionnaire, which was mailed to over 2,200 Canadian IT specialists. Of the sample, 18% returned completed questionnaires. ANOVA and t-test were used to identity differences among categories of respondents. Overall, IT practitioners\u27 scores were acceptable but not particularly impressive. Results indicate that most IT specialists could pass the test regarding their knowledge of the concepts underlying organizational change management, and in the techniques needed to implement such a process, but they were not outstanding in that knowledge. Further, senior IT managers and systems/business analysts demonstrated a better grasp of many of the issues inherent in organizational change efforts than did technical personnel. Implications of these results for research as well as practice and educational programs in IT are discussed

The neurophysiological brain-fingerprint of Parkinson’s diseaseResearch in context

Summary: Background: Research in healthy young adults shows that characteristic patterns of brain activity define individual “brain-fingerprints” that are unique to each person. However, variability in these brain-fingerprints increases in individuals with neurological conditions, challenging the clinical relevance and potential impact of the approach. Our study shows that brain-fingerprints derived from neurophysiological brain activity are associated with pathophysiological and clinical traits of individual patients with Parkinson’s disease (PD). Methods: We created brain-fingerprints from task-free brain activity recorded through magnetoencephalography in 79 PD patients and compared them with those from two independent samples of age-matched healthy controls (N = 424 total). We decomposed brain activity into arrhythmic and rhythmic components, defining distinct brain-fingerprints for each type from recording durations of up to 4 min and as short as 30 s. Findings: The arrhythmic spectral components of cortical activity in patients with Parkinson’s disease are more variable over short periods, challenging the definition of a reliable brain-fingerprint. However, by isolating the rhythmic components of cortical activity, we derived brain-fingerprints that distinguished between patients and healthy controls with about 90% accuracy. The most prominent cortical features of the resulting Parkinson’s brain-fingerprint are mapped to polyrhythmic activity in unimodal sensorimotor regions. Leveraging these features, we also demonstrate that Parkinson’s symptom laterality can be decoded directly from cortical neurophysiological activity. Furthermore, our study reveals that the cortical topography of the Parkinson’s brain-fingerprint aligns with that of neurotransmitter systems affected by the disease’s pathophysiology. Interpretation: The increased moment-to-moment variability of arrhythmic brain-fingerprints challenges patient differentiation and explains previously published results. We outline patient-specific rhythmic brain signaling features that provide insights into both the neurophysiological signature and symptom laterality of Parkinson’s disease. Thus, the proposed definition of a rhythmic brain-fingerprint of Parkinson’s disease may contribute to novel, refined approaches to patient stratification. Symmetrically, we discuss how rhythmic brain-fingerprints may contribute to the improved identification and testing of therapeutic neurostimulation targets.
