Miniaturized transducers are fabricated from commercially available four-arm semiconductor gages; transducers are connected as bridge circuit and mounted on internal face of small diaphragm. Jacket made of conductive plastic may be needed to avoid buildup or static charges

Heritage branding orientation: The case of Ach. Brito and the dynamics between corporate and product heritage brands

The notion of heritage branding orientation is introduced and explicated. Heritage branding orientation is designated as embracing both product and corporate brands and differs from corporate heritage brand orientation which has an explicit corporate focus. Empirical insights are drawn from an in-depth and longitudinal case study of Ach. Brito, a celebrated Portuguese manufacturer of soaps and toiletries. This study shows how, by the pursuance of a strategy derived from a heritage branding orientation Ach. Brito – after a prolonged period of decline – achieved a dramatic strategic turnaround. The findings reveal how institutional heritage can be a strategic resource via its adoption and activation at both the product and corporate levels. Moreover, the study showed how the bi-lateral interplay between product and corporate brand levels can be mutually reinforcing. In instrumental terms, the study shows how heritage can be activated and articulated in different ways. For instance, it can re-position both product and/or corporate brands; it can be meaningfully informed by product brand heritage and shape corporate heritage; and can be of strategic importance to both medium-sized and small enterprises

Detecting energy dependent neutron capture distributions in a liquid scintillator

A novel technique is being developed to estimate the effective dose of a neutron field based on the distribution of neutron captures in a scintillator. Using Monte Carlo techniques, a number of monoenergetic neutron source energies and locations were modelled and their neutron capture response was recorded. Using back propagation Artificial Neural Networks (ANN) the energy and incident direction of the neutron field was predicted from the distribution of neutron captures within a 6Li-loaded liquid scintillator. Using this proposed technique, the effective dose of 252Cf, 241AmBe and 241AmLi neutron fields was estimated to within 30% for four perpendicular angles in the horizontal plane. Initial theoretical investigations show that this technique holds some promise for real-time estimation of the effective dose of a neutron field

A novel approach to neutron dosimetry

Purpose: Having been overlooked for many years, research is now starting to take into account the directional distribution of neutron workplace fields. Existing neutron dosimetry instrumentation does not account for this directional distribution, resulting in conservative estimates of dose in neutron workplace fields (by around a factor of 2, although this is heavily dependent on the type of field). This conservatism could influence epidemiological studies on the health effects of radiation exposure. This paper reports on the development of an instrument which can estimate the effective dose of a neutron field, accounting for both the direction and the energy distribution. Methods: A 6Li-loaded scintillator was used to perform neutron assays at a number of locations in a 20 × 20 × 17.5 cm3 water phantom. The variation in thermal and fast neutron response to different energies and field directions was exploited. The modeled response of the instrument to various neutron fields was used to train an artificial neural network (ANN) to learn the effective dose and ambient dose equivalent of these fields. All experimental data published in this work were measured at the National Physical Laboratory (UK). Results: Experimental results were obtained for a number of radionuclide source based neutron fields to test the performance of the system. The results of experimental neutron assays at 25 locations in a water phantom were fed into the trained ANN. A correlation between neutron counting rates in the phantom and neutron fluence rates was experimentally found to provide dose rate estimates. A radionuclide source behind shadow cone was used to create a more complex field in terms of energy and direction. For all fields, the resulting estimates of effective dose rate were within 45% or better of their calculated values, regardless of energy distribution or direction for measurement times greater than 25 min. Conclusions: This work presents a novel, real-time, approach to workplace neutron dosimetry. It is believed that in the research presented in this paper, for the first time, a single instrument has been able to estimate effective dose

Cost-effectiveness of voluntary HIV-1 counseling and testing in reducing sexual transmission of HIV-1 in Kenya and Tanzania.

Background Access to HIV-1 voluntary counseling and testing (VCT) is severely limited in less-developed countries. We undertook a multisite trial of HIV-1 VCT to assess its impact, cost, and cost-effectiveness in less-developed country settings.\ud Methods\ud The cost-effectiveness of HIV-1 VCT was estimated for a hypothetical cohort of 10 000 people seeking VCT in urban east Africa. Outcomes were modelled based on results from a randomised controlled trial of HIV-1 VCT in Tanzania and Kenya. Our main outcome measures included programme cost, number of HIV-1 infections averted, cost per HIV-1 infection averted, and cost per disability-adjusted life-year (DALY) saved. We also modelled the impact of targeting VCT by HIV-1 prevalence of the client population, and the proportion of clients who receive VCT as a couple compared with as individuals. Sensitivity analysis was done on all model parameters.\ud Findings\ud HIV-1 VCT was estimated to avert 1104 HIV-1 infections in Kenya and 895 in Tanzania during the subsequent year. The cost per HIV-1 infection averted was US$249 and$346, respectively, and the cost per DALY saved was $12·77 and$17·78. The intervention was most cost-effective for HIV-1-infected people and those who received VCT as a couple. The cost-effectiveness of VCT was robust, with a range for the average cost per DALY saved of $5·16-27·36 in Kenya, and$6·58-45·03 in Tanzania. Analysis of targeting showed that increasing the proportion of couples to 70% reduces the cost per DALY saved to $10·71 in Kenya and$13·39 in Tanzania, and that targeting a population with HIV-1 prevalence of 45% decreased the cost per DALY saved to $8·36 in Kenya and$11·74 in Tanzania.\ud Interpretation\ud HIV-1 VCT is highly cost-effective in urban east African settings, but slightly less so than interventions such as improvement of sexually transmitted disease services and universal provision of nevirapine to pregnant women in high-prevalence settings. With the targeting of VCT to populations with high HIV-1 prevalence and couples the cost-effectiveness of VCT is improved significantly

When legal rights are not a reality: Do individuals know their rights and how can we tell?

Public knowledge of rights has been the subject of a number of empirical enquiries over the last decade. In England and Wales, knowledge of rights and its relationship with an individual's capacity to 'self-help' and 'self-represent' when faced with a civil justice problem has become the subject of renewed attention following changes to legal aid which, from March 2013, will see the availability of legal advice and representation dramatically reduced. Previous studies focusing on public knowledge of rights in this (and other) jurisdictions have illustrated a lack of knowledge amongst the general population and more specifically, a widespread tendency of individuals to assume that the law aligns with their own moral, ethical or social attitudes. However, many of these studies have also suffered from methodological shortcomings. In attempting to address some of these shortcomings this study uses an open-ended format to ask individuals with one or one or more civil or social justice problems to describe their rights/legal position. We find that whilst an open-ended question approach to exploring knowledge of rights yields insight not acquired by other formats, its utility is constrained by difficulty reconciling articulation and actual knowledge of rights. We discuss the implications of these findings as they relate to the development of future research in the field of family and social welfare law, Public Legal Education (PLE) and access to justice post-March 2013. © 2013 Copyright Taylor and Francis Group, LLC

Navigating the Legal Advice Maze – Knowledge, Expectations and the Reality of Advice Seeking

As law has become increasingly ubiquitous in modern life, the sources of help to deal with an increasing range of legal issues have become more fragmented and complex. Yet, despite the ubiquity of law and scale of the (broadly defined) legal services sector, there is evidence in England and Wales that public awareness of even the most prominent services is limited. How is it that people navigate the legal advice maze? What does this mean for the development of the law, legal services and access to justice? In this paper we build on the existing literature, using data from both waves of the English and Welsh Civil and Social Justice Panel Survey (CSJPS) to explore public awareness of legal services, the characteristics associated with greater/lesser knowledge of advice services, as well as what it is that consumers of legal services want from their advisors. In confirming that levels of awareness of legal services are relatively low, and that the accuracy of the public’s understanding of the types of issue that different services can help with is wanting, our findings point to the need for legal services to convey more effectively the support they can offer. Even those services that figure prominently in the public’s consciousness have work to do in more accurately targeting their services and more effectively promoting access to justice

Unmanageable Debt and Financial Difficulty in the English and Welsh Civil and Social Justice Survey: Report for the Money Advice Trust

The following report uses three years of data from the English and Welsh Civil and Social Justice Survey (CSJS), a face-to-face household survey of people’s experience of and response to rights problems, to examine respondents who reported problems associated with unmanageable debt and financial difficulty. The research was commissioned by the Money Advice Trust with the aim of enriching and supporting existing research regarding people in debt, with reference to adviceseeking strategies, impact of debt problems, and the interrelationship between debt and other problems
