Mental health needs in schools for emotional, behavioural and social difficulties
No full textWithin the UK, around 10% of children have mental health problems, but this is likely to be higher among certain specific populations. Children and young people attending provisions for social, emotional and behavioural difficulties (SEBD) are a particularly vulnerable group whose mental health needs are under-researched. The authors, Latha Hackett, Louise Theodosiou, Freya Spicer and Rachel Lever of the Winnicott Centre, Manchester, Claire Blackburn who is a clinical psychologist and Caroline Bond of Manchester University conducted a study which involved all pupils in two schools for children with SEBD. The views of parents and teachers were sought for a sample of 71 children. The Strength and Difficulties Questionnaire and a supplementary questionnaire were used to gain a broad picture of the mental health needs of this group and the services required. The findings from these questionnaires indicate a much higher than national level of perceived mental health difficulties within this population. This piece of research highlights that both teachers and parents identified a need for professional support, from education, social care, health and other services. These findings have implications for future commissioning of services. © 2010 The Author(s). Journal compilation © 2010 NASEN
Transforming Realities—Making the Improbable Possible: Reclamation of Sacredness as a Source of Generative Capacities
No full textUnderstanding the nature and source of generative capacities for radical change has been an enduring concern for researchers of organizations and social movements. However, the role of spirituality as a resource in social movements is an undertheorized area. Based on the field study of a successful, long-term social movement in India and drawing on the emerging discourse on spirituality in organizational literature, the author describes how in a community reclamation of the sacred came to be a source of generative capacities for transformation. This article describes a dynamic model of change that begins with recognition of the sacred and positive action that has the potential to spiral to escalating levels of positive change. The article also describes how the sacred in this community is manifested as a socioecological, relational ethic. The author concludes by discussing the implications of this framework for social movements and organizational change theories
The effective use of virtualization for selection of data centers in a cloud computing environment
No full textEnhancement of Underwater Images Using FPGA
No full textDue to low illumination and changing environmental circumstances, underwater photography is difficult. The obtained weak images must be upgraded due to limited light offered by the Automated Underwater Vehicles (AUV). In order to employ AUVs, image enhancing algorithms must be created in hardware. Because of their intrinsic parallelism, Field Programmable Gate Arrays (FPGA) have shown to be a superior solution for image processing approaches. Power law transform, contrast stretching, Histogram Equalization, Histogram Stretching, and Negative transformation are among the spatial domain procedures used to preprocess an underwater picture. A comparison of the above-mentioned picture enhancement technique implemented in FPGA is conducted in this work
Design and Comparison of Waveguide Windows
No full textAbstractThe waveguide Windows used in most of the high power microwave Tubes are of different types, namely the rectangular single block window, the multilayer window and the thin disc pillbox window. In this paper, the design of all the three types of windows is carried out in the X-band frequency. The design of the single block window has been carried out with inductive, capacitive and resonant type of irises to find their suitability for window applications. The results obtained from the equivalent circuit have been compared with that of results from the Electromagnetic software HFSS and presented for all the RF windows
Efficient Buffer Management Protocol for Multicast Streaming in MANET
No full textAbstractBuffer management techniques are essential while handling multicast streaming in MANET since real-time data will involve playback delay and jitter. In this paper, an efficient buffer management protocol is developed for streaming data in multicast groups. The frequently requested video data can be buffered in any intermediate nodes along the multicast tree from the source to the receivers. When packets are received, they are classified as real-time or non-real-time and placed into respective queues. Cumulative weight of the packets in the real-time buffer is then estimated based on number of hops, deadline and waiting time. Based on the estimated weight value, transmission priorities are assigned. The buffer space is dynamically adjusted depending on the number of intermediate nodes along the multicast tree from the source to the receivers. Simulation results show that the proposed buffer management protocol reduces the latency and energy consumption while increasing the packet delivery ratio
Mode Matching Method for the Analysis of Cascaded Discontinuities in a Rectangular Waveguide
No full textAbstractThe generalized scattering properties of cascaded H-plane discontinuity in a rectangular waveguide operating in X- band using Mode Matching Technique (MMT) is obtained from the respective field equations for two different junctions. The S-parameters obtained are cascaded to obtain the S-parameters for the whole system. The results obtained using MMT are compared with Equivalent circuit approach and 3-Dimensional (3-D) Electromagnetic (EM) simulation software package, Computer Simulation Technology Microwave Studio (CST-MWS) and High Frequency Structure Simulator (HFSS) which are based on Finite Integration Technique (FIT) and Finite Element Method (FEM) respectively, based on accuracy and simulation time
Data Protection Efforts in India: Blind Leading the Blind?
No full textThis paper, after establishing the need for effective data protection in India, goes on to describe the rudimentary measures taken in the country till date in the sphere of data protection. While highlighting the inadequacy of such measures and the ambiguity in proposed amendments, the author seeks inspiration from European Union law in proposing a broad framework for data protection law in India
