Relationship between affective temperaments and aggression in euthymic patients with bipolar mood disorder and major depressive disorder
So far there is a scarce of studies dealing with the relationship between different aspects of aggressive behaviour and affective temperaments among various mood disorders. The aim of the present study was to explore in a group of patients with affective mood disorders the relationship between affective temperaments and aggression.100 consecutive outpatients in euthymic phase of mood disorders (46 with bipolar disorder-type I, 18 with bipolar disorder-type II and 36 with major depressive disorder) were self-assessed with the Aggression Questionnaire and the short version of Slovenian Temperament Evaluation of Memphis, Pisa, Paris and San Diego - Autoquestionnaire (TEMPS-A).The factorial analysis of the TEMPS-A subscales revealed 2 main factors: Factor 1 (prominent cyclothymic profile) consisted of cyclothymic, depressive, irritable, and anxious temperaments and Factor 2 (prominent hyperthymic profile) which was represented by the hyperthymic temperament, and by depressive and anxious temperaments as negative components. Patients with prominent cyclothymic profile got their diagnosis later in their life and had significantly higher mean scores on anger and hostility (non-motor aggressive behaviour) compared with patients with prominent hyperthymic profile.We included patients with different mood disorders, therefore the sample selection may influence temperamental and aggression profiles. We used self-report questionnaires which can elicit sociable desirable answers.Anger and hostility could represent stable personality characteristics of prominent cyclothymic profile that endure even in remission. It seems that distinct temperamental profile could serve as a good diagnostic and prognostic value for non-motor aspects of aggressive behaviour
FPGA Development Approach for Accelerator Systems with High Integration Complexity”. In: IPAC2013
Abstract This paper presents a Field Programmable Gate Array (FPGA) development workflow for custom hardware as part of an accelerator control systems. The workflow is narrowed down to three equally important parts: requirements analysis, implementation and testing. Each part is presented with milestones and guidelines, which addresses subjects such as knowledge alignment and development standards. These are presented and have been proven to increase efficiency and quality of control systems
Using the physical properties of artefacts to manage through‐life knowledge flows in the built environment: an initial exploration
Effective through‐life management of built facilities requires effective through‐life knowledge management to support it. The KIM (Immortal Information and Through‐Life Knowledge Management) project attempted to develop such an approach, based on a dichotomy of knowledge and information. Knowledge is conceived in terms of communities of practice. An initial philosophical analysis demonstrates deficiencies in this conception. Drawing inspiration from production theory, a tripartite analysis is offered, suggesting that knowledge flows consist of: social practices, information and physical properties. Literature on physical properties from design studies, production management and ethnomethodology is briefly reviewed to demonstrate the information bearing functions of physical properties. Fieldwork conforming to the unique adequacy requirement of methods was carried out on construction sites, in hotel and hospital facilities during the use stage of their life cycles. Safety barriers on construction sites were found to have informational properties beyond their function as a physical barrier. The quality of information delivered by wayfinding signs was found to depend upon both the physical placement of the signs in relation to the surrounding environment and the physical layout of the sign itself. It was found that social practices are institutionalized to repair the knowledge flow when the physically instantiated wayfinding system breaks down. Finally, through the investigation of practices surrounding emergency resuscitation equipment, it was found that if the physical properties of information are not designed to mesh with the work practices of the setting, this will lead to a breakdown in the knowledge flow. It is suggested that elements of knowledge management, ethnomethodology, production management and design studies might be integrated to form the basis of a hybrid discipline
39K NMR and EPR study of multiferroic K3Fe5F15
39K NMR spectra and relaxation times of polycrystalline K3Fe5F15 have
been used as a microscopic detector of the local magnetic fields at
the magnetic transition at TN = 123 K. The NMR lineshape widens
abruptly upon crossing TN due to the onset of internal magnetic
fields, while we find no significant lineshift. The paraelectric to
ferroelectric transition at Tc = 490 K and the magnetic transition at
TN have also been studied using X-band EPR (electron paramagnetic
resonance). An increase and subsequent decrease in the EPR
susceptibilities is observed on approaching TN from above. There is
also a significant increase in the linewidth. At the same time the
g-factor first decreases and then increases with decreasing
temperature. The local magnetic field is different at different K
sites and is much smaller than the magnetic field around the Fe sites.
This seems to be consistent with the behaviour of a weak ferrimagnet.
The ferrimagnetism does not seem to be due to spin canting as the
lattice is disordered, but may arise from thermal blocking of
superparamagnetic percolation clusters. The ferroelectric transition
at Tc shows no electronic anomaly, demonstrating that we are dealing
with a classical phonon anomaly as found in conventional oxides rather
than an electronic transition
