E-readiness in construction (ERiC) : self-assessment framework for UK small and medium enterprise building services providers

The construction industry’s ability to innovate in order to improve its practices has been widely debated. As organisations in other sectors globally are addressing technology challenges, is the UK construction industry e-ready? Of particular concern is the plethora of small and medium enterprises (SME) that constitute over 80% of the UK construction industry. There are noticeable SME laggards in the uptake of new processes and technologies. This paper aims to assess the e-readiness levels of UK SME building services provider in order to leverage the advantages of technology opportunities in the future. The resultant self-assessment ERiC framework enables SMEs to quantify and measure e-readiness from an organisation, technical and process perspective

Carrying out research across the arts and humanities and social sciences: developing the methodology for Dementia and Imagination

This paper analyses how the methodological approach for a major Arts and Humanities Research Council and Economic and Social Research Council-funded project entitled Dementia and Imagination1 was formulated. This multidisciplinary project brings together the arts and humanities with the social sciences with their different epistemological philosophies and subsequent understandings of research methods. The main objective was to determine how visual arts activities may change, sustain and catalyse community cultures, beliefs, attitudes and behaviours to create dementia-friendly communities. This project involves 6 different UK universities, 14 researchers, 10 formal partners, 7 project artists, 3 research artists and a large number of civil society organisations. The analysis presents a series of themes that have been identified as influencing the approach taken to develop methods which aimed to speak to different audiences in the social sciences, arts and humanities, policy/practice and public domains. It is concluded that a research project of this type needs to embrace a wide variety of epistemological positions if it is to successfully achieve its objectives. This paper contributes to knowledge about how the methodology of large-scale multidisciplinary projects may be constructed which will be of value to those building research consortia across different universities and between universities and community partners. © 2016 The Author(s).

Exploring concepts of health with male prisoners in three category-C English prisons

Lay understandings of health and illness have a well established track record and a plethora of research now exists which has examined these issues. However, there is a dearth of research which has examined the perspectives of those who are imprisoned. This paper attempts to address this research gap. The paper is timely given that calls have been made to examine lay perspectives in different geographical locations and a need to re-examine health promotion approaches in prison settings. Qualitative data from thirty-six male sentenced prisoners from three prisons in England were collected. The data was analysed in accordance with Attride-Stirling's (2001) thematic network approach. Although the men's perceptions of health were broadly similar to the general population, some interesting findings emerged which were directly related to prison life and its associated structures. These included access to the outdoors and time out of their prison cell, as well as maintaining relationships with family members through visits. The paper proposes that prisoners' lay views should be given higher priority given that prison health has traditionally been associated with medical treatment and the bio-medical paradigm more generally. It also suggests that in order to fulfil the World Health Organization's (WHO) vision of viewing prisons as health promoting settings, lay views should be recognised to shape future health promotion policy and practice

CCL3L1 copy number, CCR5 genotype and susceptibility to tuberculosis

Background: Tuberculosis is a major infectious disease and functional studies have provided evidence that both the chemokine MIP-1α and its receptor CCR5 play a role in susceptibility to TB. Thus by measuring copy number variation of CCL3L1, one of the genes that encode MIP-1α, and genotyping a functional promoter polymorphism -2459A > G in CCR5 (rs1799987) we investigate the influence of MIP-1α and CCR5, independently and combined, in susceptibility to clinically active TB in three populations, a Peruvian population (n = 1132), a !Xhosa population (n = 605) and a South African Coloured population (n = 221). The three populations include patients with clinically diagnosed pulmonary TB, as well as other, less prevalent forms of extrapulmonary TB. Methods and results: Copy number of CCL3L1 was measured using the paralogue ratio test and exhibited ranges between 0–6 copies per diploid genome (pdg) in Peru, between 0–12 pdg in !Xhosa samples and between 0–10 pdg in South African Coloured samples. The CCR5 promoter polymorphism was observed to differ significantly in allele frequency between populations (*A; Peru f = 0.67, !Xhosa f = 0.38, Coloured f = 0.48). Conclusions: The case–control association studies performed however find, surprisingly, no evidence for an influence of variation in genes coding for MIP-1α or CCR5 individually or together in susceptibility to clinically active TB in these populations

Modulation of RANTES expression by HCV core protein in liver derived cell lines

<p>Abstract</p> <p>Background</p> <p>Hepatitis C virus (HCV) infection is associated with high percentage of chronicity which implies the ability of the virus to evade or modulate host cell immune system. Modulation of chemokines, such as RANTES may be part of the virus induced pathogenicity. We examined the effect of core and structural proteins of HCV on RANTES expression in two liver derived cell lines, HepG2 and Chang Liver (CHL).</p> <p>Methods</p> <p>HepG2 and Chang Liver (CHL) cell lines were established and selected for constitutive expression of HCV core and structural genes. Flow cytometry and quantitative RT-PCR analysis were performed to examine the effect of HCV core protein on RANTES expression. Luciferase analysis after RANTES-Luc-promoter transfection of established cell lines was assayed by luminometer measurements (RLU) of RANTES promoter activity. IRF-1 and IRF-7 expression was then examined by immunoblotting analysis.</p> <p>Results</p> <p>Results of flow cytometry and RT-PCR analysis indicated that RANTES is differentially regulated by HCV core protein in the two cell lines examined as its expression was inhibited in HepG2 cells, by a reduction of RANTES promoter activity. Conversely, RANTES protein and mRNA were induced by the core protein in CHL cells, through the induction of the promoter.</p> <p>Since HCV genome modulates IRF-1 and IRF-7 in replicon system and IRF-1, IRF-3 and IRF-7 have been reported to regulate RANTES promoter in various cell systems, analysis of the mechanism underlying RANTES modulation by the core protein revealed that IRF-1 expression was induced in HepG2 cells by the core protein, whereas in CHL cells it was expressed at a very low level that was not influenced by transfection with the core protein construct. This suggested that IRF-1 level may mediate the expression of RANTES in cell lines of liver origin. The effect of the core protein on RANTES promoter was countered by co-transfection with NF90, a double-stranded-RNA binding protein that activates some interferon response genes and acts as a component of cell defense against viral infection.</p> <p>Conclusion</p> <p>HCV core protein have opposite effects on the expression of RANTES in different cell types <it>in vitro</it>, possibly reflecting a similar scenario in different microenvironments <it>in vivo</it>.</p

Cortical histomorphometry of the human humerus during ontogeny

Modeling and remodeling are two key determinants of human skeletal growth though little is known about the histomorphometry of cortical bone during ontogeny. In this study we examined the density and geometric properties of primary and secondary osteons (osteon area and diameter, vascular canal area and diameter) in sub-periosteal cortical bone from the human humerus (n=84) between birth and age 18 years. Sections were removed from the anterior midshaft aspect of humeri from skeletons. Age-at-death was reconstructed using standard osteological techniques. Analyses revealed significant correlation between the histomorphometric variables and age. Higher densities of primary osteons occurred between infancy and seven years of age but were almost completely replaced by secondary osteons after 14 years of age. The geometry of primary osteons was less clearly related to age. Secondary osteons were visible after two years of age, and reached their greatest densities in the oldest individuals. Osteon size was positively but weakly influenced by age. Our data implies that modeling and remodeling are age dependent processes that vary markedly from birth to adulthood in the human humerus

The Mycobacterium tuberculosis Drugome and Its Polypharmacological Implications

We report a computational approach that integrates structural bioinformatics, molecular modelling and systems biology to construct a drug-target network on a structural proteome-wide scale. The approach has been applied to the genome of Mycobacterium tuberculosis (M.tb), the causative agent of one of today's most widely spread infectious diseases. The resulting drug-target interaction network for all structurally characterized approved drugs bound to putative M.tb receptors, we refer to as the ‘TB-drugome’. The TB-drugome reveals that approximately one-third of the drugs examined have the potential to be repositioned to treat tuberculosis and that many currently unexploited M.tb receptors may be chemically druggable and could serve as novel anti-tubercular targets. Furthermore, a detailed analysis of the TB-drugome has shed new light on the controversial issues surrounding drug-target networks [1]–[3]. Indeed, our results support the idea that drug-target networks are inherently modular, and further that any observed randomness is mainly caused by biased target coverage. The TB-drugome (http://funsite.sdsc.edu/drugome/TB) has the potential to be a valuable resource in the development of safe and efficient anti-tubercular drugs. More generally the methodology may be applied to other pathogens of interest with results improving as more of their structural proteomes are determined through the continued efforts of structural biology/genomics

Intra-tumoural microvessel density in human solid tumours

Over the last decade assessment of angiogenesis has emerged as a potentially useful biological prognostic and predictive factor in human solid tumours. With the development of highly specific endothelial markers that can be assessed in histological archival specimens, several quantitative studies have been performed in various solid tumours. The majority of published studies have shown a positive correlation between intra-tumoural microvessel density, a measure of tumour angiogenesis, and prognosis in solid tumours. A minority of studies have not demonstrated an association and this may be attributed to significant differences in the methodologies employed for sample selection, immunostaining techniques, vessel counting and statistical analysis, although a number of biological differences may account for the discrepancy. In this review we evaluate the quantification of angiogenesis by immunohistochemistry, the relationship between tumour vascularity and metastasis, and the clinicopathological studies correlating intra-tumoral microvessel density with prognosis and response to anti-cancer therapy. In view of the extensive nature of this retrospective body of data, comparative studies are needed to identify the optimum technique and endothelial antigens (activated or pan-endothelial antigens) but subsequently prospective studies that allocate treatment on the basis of microvessel density are required

The Transformation from Traditional Nonprofit Organizations to Social Enterprises: An Institutional Entrepreneurship Perspective

The development of commercial revenue streams allows traditional nonprofit organizations to increase financial certainty in response to the reduction of traditional funding sources and increased competition. In order to capture commercial revenue-generating opportunities, traditional nonprofit organizations need to deliberately transform themselves into social enterprises. Through the theoretical lens of institutional entrepreneurship, we explore the institutional work that supports this transformation by analyzing field interviews with 64 institutional entrepreneurs from UK-based social enterprises. We find that the route to incorporate commercial processes and convert traditional nonprofit organizations into social enterprises requires six distinct kinds of institutional work at three different domains; these are—“engaging commercial revenue strategies”, “creating a professionalized organizational form”, and “legitimating a socio-commercial business model”. In elaborating on social entrepreneurship research and practice, we offer a comprehensive framework delineating the key practices contributing to the transformation from traditional nonprofit organizations to social enterprises. This extends our understanding of the ex-ante strategy of incorporating commercial processes within social organizations. Furthermore, the identification of these practices also offers an important tool for scholars in this field to examine the connection (or disconnection) of each practice with different ethical concerns of social entrepreneurship in greater depth.British Academ
