Tracking Rotational Diffusion of Colloidal Clusters

We describe a novel method of tracking the rotational motion of clusters of colloidal particles. Our method utilizes rigid body transfor- mations to determine the rotations of a cluster and extends conventional proven particle tracking techniques in a simple way, thus facilitating the study of rotational dynamics in systems containing or composed of colloidal clusters. We test our method by measuring dynamical properties of simulated Brownian clusters under conditions relevant to microscopy experiments. We then use the technique to track and describe the motions of a real colloidal cluster imaged with confocal microscopy.Comment: 14 pages, 6 figures. Submitted to Optics Expres

Unsettling planning theory

Recent political developments in many parts of the world seem likely to exacerbate rather than ameliorate the planetary-scale challenges of social polarization, inequality and environmental change societies face. In this unconventional multi-authored essay, we therefore seek to explore some of the ways in which planning theory might respond to the deeply unsettling times we live in. Taking the multiple, suggestive possibilities of the theme of unsettlement as a starting point, we aim to create space for reflection and debate about the state of the discipline and practice of planning theory, questioning what it means to produce knowledge capable of acting on the world today. Drawing on exchanges at a workshop attended by a group of emerging scholars in Portland, Oregon in late 2016, the essay begins with an introduction section exploring the contemporary resonances of ‘unsettling’ in, of and for planning theory. This is followed by four, individually authored responses which each connect the idea of unsettlement to key challenges and possible future directions. We end by calling for a reflective practice of theorizing that accepts unsettlement but seeks to act knowingly and compassionately on the uneven terrain that it creates

Sensoria Patterns: Augmenting Service Engineering with Formal Analysis, Transformation and Dynamicity

The IST-FET Integrated Project Sensoria is developing a novel comprehensive approach to the engineering of service-oriented software systems where foundational theories, techniques and methods are fully integrated into pragmatic software engineering processes. The techniques and tools of Sensoria encompass the whole software development cycle, from business and architectural design, to quantitative and qualitative analysis of system properties, and to transformation and code generation. The Sensoria approach takes also into account reconfiguration of service-oriented architectures (SOAs) and re-engineering of legacy systems. In this paper we give first a short overview of Sensoria and then present a pattern language for augmenting service engineering with formal analysis, transformation and dynamicity. The patterns are designed to help software developers choose appropriate tools and techniques to develop service-oriented systems with support from formal methods. They support the whole development process, from the modelling stage to deployment activities and give an overview of many of the research areas pursued in the Sensoria project

Caregiver's experience of Rehabilitation for children with cerebral palsy: A Qualitative Study

The aim of the study was to explore the caregiver's experience of rehabilitation for children with cerebral palsy. The hypothesis of the study was that caregivers had a major role in rehabilitation process and rehabilitation helps in improving the motor and social milestones of the child with cerebral palsy. It was a qualitative study in which in-depth face to face, semi structured interviews were taken from 11 caregivers of cerebral palsy from different rehabilitation centres. A questionnaire was deveoped by the prime reseacher in which questions regarding the rehabilitation experience, barriers and facilitators, social engagemnet were framed. The interview questions were based on a thorough review of literature. Participants who were caregiver of a child with cerebral palsy and who volunteered to participate in the study were included in this study. Participants who had communication problems were excluded. The interviews were audio recorded and were written in english & transcribed verbatim. The transcribed interviews were then entered into a QDA Miner Lite software for data analysis. The data analysis was done and various themes and sub themes were obtained from interview transcripts. Total 10 themes and 46 sub-themes were obtained. The themes were staff, overall experience, motor recovery, Barriers & facilitators in rehabilitation, cognitive and perceptual abilities, caregiver's burden, psychological effects, glimmer of hope, speech. The participants discussed their experiences with the interaction with the staff at rehabiltation centre. They told about the Motor recovery of the child which included Improvement in oromotor functions, improvement in motor milestones, improved activities of daily living, improved posture and prevention of secondary complications as a result of rehabilitation. These findings have an important role in clinical settings and rehabilitation of a child with cerebral palsy. The coded transcripts were also sent back to participants for member checking. On the basis of this study , it was concluded that caregivers had a major role in prognosis of the child.Also rehabilitation plays an important role in achieving the motor milestones in the children with cerebral palsy.THIS DATASET IS ARCHIVED AT DANS/EASY, BUT NOT ACCESSIBLE HERE.
