Are Existing Security Models Suitable for Teleworking?

The availability of high performance broadband services from the home will allow a growing number of organisations to offer teleworking as an employee work practice. Teleworking delivers cost savings, improved productivity and provides a recruitment policy to attract and retain personnel. Information security is one of the management considerations necessary before an effective organisational teleworking policy can be implemented. The teleworking computing environment presents a different set of security threats to those present in an office environment. Teleworking requires a security model to provide security policy enforcement to counter the set of security threats present in the teleworking computing environment. This paper considers four existing security models and assesses each model’s suitability to define security policy enforcement for telework. The approach taken is to identify the information security threats that exist in a teleworking environment and to categorise the threats based upon their impact upon confidentiality of data, system and data integrity, and availability of service in the teleworking environment. It is found that risks exist to the confidentiality, integrity and availability of information in a teleworking environment and therefore a security model is required that provides appropriate policy enforcement. A set of security policy enforcement mechanisms to counter the identified information security threats is proposed. Using an abstraction of the identified threats and the security policy enforcement mechanisms, a set of attributes for a security model for teleworking is proposed. Each of the four existing security models is assessed against this set of attributes to determine its suitability to specify policy enforcement for telework. Although the four existing models were selected based upon their perceived suitability it is found that none provide the required policy enforcement for telework

Application of a news quality monitoring methodology

This set of case studies has two main purposes Case studies illustrating the usefulness of the quality monitoring framework set out in chapter one of The Future of Quality News Journalism: a cross-continental analysis The material that is produced below is still under development and may be modified when the final draft is produced shortly. a) Introduction This set of case studies has two main purposes. First, to provide examples of how the quality monitoring framework outlined in chapter one might be applied to online news stories of quality mainstream news providers. Second, to provide some representative sample evidence of the quality of the hard news provision of some of the best of the mainstream news providers. This is intended to back up the case for their continuing importance that is made within the bonus chapter (available only online at: HTTP://CLOK.UCLAN.AC.UK/7824) There are several things that it is important to emphasise. First, as chapter one makes clear, the preferred means of quality assessment would be via the kind of expert/professional panels outlined and suggested there. This should enhance the rigour of the evaluative process in so far as several pairs of expert eyes are likely to pick up inconsistencies in the application of that process in a way that would not be possible for one. Given that such panels do not yet exist to apply it and that the purpose here is mainly illustrative, the evaluations have been made by the author alone. That means that they should be treated with greater caution than had they been panel produced, but providing that is remembered it does not detract from their illustrative value. For the purposes of transparency and the need to provide readers with enough information to help them cross-check the judgments for themselves if they so wish, concise sample reasons are provided at the end of each piece as to why the individual quality ratings have been arrive

Absorption and dispersion spectroscopy in the far infra-red region

The work described in this thesis can be divided into two main parts. The first part describes the modifications of the instrument (a Beckman-RIIC FS720) to enable it to be operated in the polarising mode with a liquid helium cooled detector. Several problems were encountered during the testing of this equipment particularly when operating the polarising system. Initially the spectra recorded with this system showed considerable distortion in the high and low frequency regions. The low frequency distortion was found to arise from electrical non-linearity (due to overload) within the electronics (RIIC FS200) and modifications to the amplifier have, eliminated this problem. The high frequency distortion, which appears as a ≈120 cm(^-1)limit, has not been corrected and is now thought to arise from a 'software' (computing) problem. The signal-to-noise ratio tests carried out on the cooled detsctor indicate that the bolometer element may not be operating at its most sensitive temperature due to overheating by the hot source. However, when operating with heavy optical filtering (therefore reducing the radiation reaching the bolometer) it has been possible to record spectra in the very far-infrared region (20 -» 5 cm(^-1)).The second part of the thesis describes the practical operation and tests carried out on the previously constructed cell designed for conversion of the instrument to operate in the dispersive mode. To enable this cell to be mounted vertically on the instrument a top window has been included to hold a liquid sample. This leads to the appearance of reflections and multiple reflections not present when studying a gravity held liquid. These reflection fringes have been fully assigned and therefore it has been possible to obtain the continuous dispersion (refractive index) curve of a liquid in the far- infrared region. The overall aim of this work has been to test the limitations and accuracy of the new equipment and make original studies in the far-infrared region

Maintaining safety : the social support and monitoring of men who have completed therapy for sexual offending : a thesis presented in partial fulfilment of the requirements for the degree of Master of Philosophy in Social Policy and Social Work at Massey University

Many consumers are conscious of the potential health problems incurred by the high consumption of fat. Consequently, they are discouraged from drinking whole milk due to its high fat content, despite its nutritional benefits, e.g. as a calcium source. A variety of low-fat milk products are currently available, with fat contents ranging from 0.1 % to 1.5 % fat. However, it is known that many consumers prefer the mouthfeel characteristics of high-fat milk. The consistency of low-fat milks was perceived as watery and the colour was often described as "green" or "grey". This identified a need for a low-fat milk product with mouthfeel characteristics and colour similar to high-fat milk. Attempts to improve the texture of low-fat milks have included the addition of non-fat milk solids to skim milk. Phillips et al. (1995) added 2 % non-fat dry milk powder to fluid skim milk. The addition of non-fat milk solids produced an objective measure of viscosity similar to milk with 2 % added fat. However, the colour and texture attributes of milk with 2 % added non-fat milk solids did not improve to such an extent that non-fat milk solids could be used as a substitute for fat

Mummies and masquerades: English and Caribbean connections

The composite mumming play script that the Ecclesfield-based Victorian children's author Juliana Horatia Ewing published in 1884 found its way to St. Kitts and Nevis in the Caribbean, where it was it was taken up enthusiastically by the black population as one of its Christmas Sports. The Mummies continue to act (and dance) to this day. Economic migrants took the Christmas Sports in turn to the Dominican Republic, in particular around the town of San Pedro de Macoris, where the performers recently gained a UNESCO Cultural Heritage Award. This paper derives from a presentation based around two videos, presented here as story boards. Millington introduces Ewing's play, and footage of the St Kitts Mummies and the Bull Play filmed by Joan McMurray. James continues the story by introducing footage of the related tradition from the Dominican Republic called the Wild Indians in English and Los Guloyas (the Goliaths) in Spanish
