Vehicular ad hoc networks (VANETs): Current state, challenges, potentials and way forward

Abstract: Recent advances in wireless communication technologies and auto-mobile industry have triggered a significant research interest in the field of VANETs over the past few years. VANET consists of vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications supported by wireless access technologies such as IEEE 802.11p. This innovation in wireless communication has been envisaged to improve road safety and motor traffic efficiency in near future through the development of Intelligent Transport Systems (ITS). Hence, government, auto-mobile industries and academia are heavily partnering through several ongoing research projects to establish standards for VANETs. The typical set of VANET application areas, such as vehicle collision warning and traffic information dissemination have made VANET an interested field of wireless communication. This paper provides an overview on current research state, challenges, potentials of VANETs as well the way forward to achieving the long awaited ITS.

Enhancing Wellbeing in Social Work Students: Building Resilience in the Next Generation

Abstract: The need for social workers to be resilient is widely emphasised. Although enhancing resilience in social work trainees presents a challenge to educators, they are nonetheless responsible for developing professionals who are able to cope with the emotional demands of the job. This paper argues that building resilience in the future workforce should be a key element of social work education. However, as little is known about the competencies and support structures that underpin resilience or the extent to which resilience protects the wellbeing of trainees, an evidence-based approach is required to inform curriculum development. Recent research conducted by the authors of this paper has highlighted the protective nature of resilience in social work trainees. Emotional intelligence and associated competencies, such as reflective ability, aspects of empathy and social confidence, were found to be key predictors of this important quality. The important role played by social support from various sources was al...

Evolution and sustainability of a wildlife monitoring sensor network

Abstract: As sensor network technologies become more mature, they are increasingly being applied to a wide variety of applications, ranging from agricultural sensing to cattle, oceanic and volcanic monitoring. Significant efforts have been made in deploying and testing sensor networks resulting in unprecedented sensing capabilities. A key challenge has become how to make these emerging wireless sensor networks more sustainable and easier to maintain over increasingly prolonged deployments.In this paper, we report the findings from a one year deployment of an automated wildlife monitoring system for analyzing the social co-location patterns of European badgers (Meles meles) residing in a dense woodland environment.We describe the stages of its evolution cycle, from implementation, deployment and testing, to various iterations of software optimization, followed by hardware enhancements, which in turn triggered the need for further software optimization. We report preliminary descriptive analyses of a subset of the data collected, demonstrating the significant potential our system has to generate new insights into badger behavior. The main lessons learned were: the need to factor in the maintenance costs while designing the system; to look carefully at software and hardware interactions; the importance of a rapid initial prototype deployment (this was key to our success); and the need for continuous interaction with domain scientists which allows for unexpected optimizations.

Assessment of bacterial viability status by flow cytometry and single cell sorting

Abstract: Rapid bacterial detection and viability measurements have been greatly enhanced by recent advances in the use of fluorescent stains in cytometry. It has previously been shown that four physiological states can be distinguished: reproductively viable, metabolically active, intact and permeabilized. Previous sorting experiments have shown that not all intact cells readily grow, but some intact cells can grow even when they fail to show metabolic activity, as determined by esterase turnover. To circumvent the limitations imposed by active dye extrusion or cell dormancy on viability measurements used to date (e.g., enzyme activity or cell polarization), a fast triple fluorochrome staining procedure has been developed that takes account of these problems. This allows further cellular characterization of intact cells by: active exclusion of ethidium bromide (EB) (metabolically active cells), uptake of EB but exclusion of bis-oxonol (BOX) (de-energized but with a polarized cell membrane) and uptake of both dyes (depolarized). Permeabilized cells were identified by propidium iodide (PI) uptake. The method was validated using an electronically programmable single cell sorter (EPICS Elite) and aged Salmonella typhimurium cells. Reproductive viability was determined by sorting single cells to their staining pattern directly onto agar plates. Most polarized cells could be recovered as well as a significant fraction of the depolarized cells, demonstrating that depolarization is a sensitive measure of cell damage but a poor indicator of cell death.
