Joint complex diversity coding and channel coding over space, time and frequency

This study provides a general diversity analysis for joint complex diversity coding (CDC) and channel coding-based space-time-frequency codeing is provided. The mapping designs from channel coding to CDC are crucial for efficient exploitation of the diversity potential. This study provides and proves a sufficient condition of full diversity construction with joint three-dimensional CDC and channel coding, bit-interleaved coded complex diversity coding and symbol-interleaved coded complex diversity coding. Both non-iterative and iterative detections of joint channel code and CDC transmission are investigated. The proposed minimum mean-square error-based iterative soft decoding achieves the performance of the soft sphere decoding with reduced complexity.

The justice-workplace health relationship:The mediating role of emotions

Purpose - The purpose of this paper is to examine the mediational effects of positive and negative emotions in the relationship between organisational justice and health. Design/methodology/approach - This cross-sectional research obtained data from 206 workers employed within the financial/banking, manufacturing, and retail industries in Barbados. Findings - Structural equation modelling analyses revealed that positive and negative emotions completely mediated the effects of relational justice (but not procedural justice) on overall health. Research limitations/implications - Research was cross-sectional, and relied on self-report measures. The findings suggest that employers must properly evaluate their health and safety policies and practices in the organisation to ensure that aspects of the psychosocial work environment are being properly implemented, managed, and monitored, to ensure that individuals' health and well-being are not at risk. Originality/value - The paper represents a first attempt to investigate the roles of positive and negative emotions in the justice-health relationship in a different cultural context such as the Caribbean. Justice has been rarely researched as a psychosocial work stressor. The study described in the paper focused on multiple health outcomes. Copyright © 2012 Emerald Group Publishing Limited.

“They might as well be walking around the inside of a biscuit tin”: Barriers to Employment and Reintegration for ‘Politically Motivated’ Former Prisoners in Northern Ireland

The prisoner provisions under the Northern Ireland Peace Agreement clearly emphasised the importance of the reintegration and civic inclusion of ‘politically motivated’ former prisoners; however, numerous barriers to full reintegration remain. Even though these prisoners were released as part of a peace process, based on principles of conflict transformation and reconciliation, there were still The prisoner provisions under the Northern Ireland Peace Agreement emphasised the importance of the reintegration and civic inclusion of ‘politically motivated’ former prisoners; however, numerous barriers to full reintegration remain. Notwithstanding the fact that these prisoners were released as part of a peace process, based on principles of conflict transformation and reconciliation, there were still numerous conditions placed upon them as part of their release process and they continued to hold a ‘criminal’ record upon release. As with ‘ordinary’ ex-prisoners, these ‘politically motivated’ former prisoners have subsequently faced numerous obstacles in their attempts to reintegrate back into society, particularly in the area of employment. Recognising that they needed to deal with the consequences of imprisonment, ‘politically motivated’ former prisoners formed numerous self-help organisations to assist in the reintegration process and have mobilised to lobby for protection against the discrimination and unequal treatment experienced by ex-prisoners seeking employment. This article explores the remaining barriers to employment for ‘politically motivated’ former prisoners and the consequences of these barriers. The article moves to assess how prisoner groups have subsequently used a ‘rights based’ discourse to engage local government in their struggle to overcome existing obstacles before finally concluding that any piecemeal attempt to remove barriers to full reintegration will only impede the longer term conflict transformation process in Northern Ireland.

Tobramycin Inhalation Powder™:a novel drug delivery system for treating chronic Pseudomonas aeruginosa infection in cystic fibrosis

Lung disease in cystic fibrosis (CF) is typified by the development of chronic airways infection culminating in bronchiectasis and progression to end-stage respiratory disease. Pseudomonas aeruginosa, a ubiquitous gram-negative bacteria, is the archetypical CF pathogen and is associated with an accelerated clinical decline. The development and widespread use of chronic suppressive aerosolized antibacterial therapies, in particular Tobramycin Inhalation Solution (TIS), in CF has contributed to reduced lung function decline and improved survival. However, the requirement for the aerosolization of these agents through nebulizers has been associated with increased treatment burden, reduced quality of life and remain a barrier to broader uptake. Tobramycin Inhalation Powder (TIP™) has been developed by Novartis with the express purpose of delivering the same benefits as TIS in a time-effective manner. Administered via the T-326™ (Novartis) Inhaler in four individual 28-mg capsules, TIP can be administered in a quarter of the time of traditional nebulizers and is inherently portable. In clinical studies, TIP has been shown to be safe, result in equivalent or superior reductions in P. aeruginosa sputum density and produce similar improvements in pulmonary function. TIP offers significant advantages in time saving, portability and convenience over traditional nebulized TIS with comparable clinical outcomes for individuals with CF.

'Strange Visitor From Another Planet': Genre, Corporate Identity and the Arrival of American Telefantasy on British Television

While the BBC had been broadcasting television Science Fiction productions from as early as 1938, and Horror since the start of television in 1936, American Telefantasy had no place on British television until ITV’s broadcast of Adventures of Superman (1952-1958) in 1956. It would be easy to assign this absence to the avoidance of popular American programming, but this would ignore the presence of Western and adventure serials imported from the US and Canada for monopoly British television. Similarly, it would be inaccurate to suggest that these imports were purely purchased as thrilling fare to appease a child audience, as it was the commercial ITV that was first to broadcast the more adult-orientated Science Fiction Theatre (1955-7) and Inner Sanctum (1954). This article builds on the work of Paul Rixon and Rob Leggott to argue that these imports were used primarily to supply relatively cheap broadcast material for the new channel, but that they also served to appeal to the notion of spectacular entertainment attached to the new channel through its own productions, such as The Invisible Man (1958-1959) and swashbucklers such as The Adventures of Robin Hood (1955-60). However, the appeal was not just to the exciting, but also to the transatlantic, with ITV embracing this conception of America as a modern place of adventure through its imports and its creation of productions for export, incorporating an American lead into The Invisible Man and drawing upon an (inexpensive) American talent pool of blacklisted screenwriters to provide a transatlantic style and relevance to its own adventure series. Where the BBC used its imported serials as filler directed at children, ITV embraced this transatlantic entertainment as part of its identity and differentiation from the BBC.
