Mapping Six New Susceptibility to Colon Cancer ( Scc ) Loci Using a Mouse Interspecific Backcross
Colorectal cancer (CRC) has a complex etiology resulting from the combination of multiple genetic and environmental factors, each with small effects. Interactions among susceptibility modifier loci make many of the loci difficult to detect in human genome-wide association studies. Previous analyses in mice have used classical inbred strains, which share large portions of their genomes due to common ancestry. Herein, we used an interspecific backcross between the Mus musculus strain A/J and the Mus spretus strain SPRET/EiJ to map 6 additional CRC modifier loci (Scc16-21) and 2 suggestive loci. Three loci modify the location of tumors along the proximal-distal axis of the colon. Six CRC modifiers previously mapped in intraspecific crosses were also replicated. This work confirms genetic models suggesting that CRC is caused by many small effect alleles and brings the catalog of reported CRC modifier loci to 23 spread across 13 chromosomes. Furthermore, this work provides the foundation for large population-level epistatic interaction tests to identify combinations of low effect alleles that may have large effects on CRC susceptibility
Quality of life among Latina breast cancer patients: a systematic review of the literature
Introduction
The Latino population is the most rapidly growing ethnic minority in the United States and Latinas have higher rates of advanced breast cancer and more rigorous treatments than White women. However, the literature lacks reviews on quality of life among this population of breast cancer patients.
Methods
A systematic review of the breast cancer quality of life (QOL) literature was conducted among studies that provided a comparison of mental, physical, social, or sexual QOL between Latinas and other racial/ethnic groups. Of the 375 studies reviewed, 20 quantitative studies and two qualitative studies met criteria for inclusion.
Results
Latinas were more likely to report poor mental, physical, and social QOL, relative to non-Latinas. Only four studies assessed sexual QOL, making it difficult to draw any conclusions. Of these four QOL domains, the largest disparity was found in the area of mental health in which Latinas reported poorer QOL compared to non-Latina Whites and Blacks.
Discussion/conclusions
Most quantitative studies revealed either that Latinas consistently evidenced significantly lower QOL than non-Latinas on all measures (6 studies) or reported mixed findings in which Latinas generally demonstrated significantly worse QOL on most, but not all, measures (12 studies) included in the study. Explanatory mechanisms including socio-demographic, treatment-related, and culturally-relevant factors are discussed. Implications for research design, measurement, and clinical work are also included.
Implications for cancer survivors
Although not entirely consistent, data suggest that Latina breast cancer survivors on average experience worse QOL than non-Latina Whites.
Understanding ethnic differences in QOL among breast cancer survivors can inform interventions targeted at improving health status for Latinas

The channel tunnel: An opportunity for london's tourism industry?
Stephen J. Page, and M. Thea Sinclair, 'THE CHANNEL TUNNEL: An opportunity for London's Tourism Industry?', Tourism Recreation Research, Vol. 17 (2): 57-70, January 1992, doi: http://dx.doi.org/10.1080/02508281.1992.11014650.The Channel Tunnel between Great Britain and France is the largest construction project in Europe and has implications for the size and nature of tourism. The economic impact of this new tourism opportunity upon London in particular is discussed within the framework of planning for the region in general. © 1992 Taylor and Francis Group, LLC.Peer reviewe
No escape? The coordination problem in heritage preservation
Conservation Areas (CAs) are among the most restrictive English planning policies. Designation implies a significant limitation of owners' control over the shape and appearance of their properties. The policy, however, can also be argued to solve a sort of ‘prisoner's dilemma’, in which it might be collectively rational to preserve the character of an area, but an individual homeowner may be tempted to inappropriately alter their property, thus free-riding on nearby properties' character. The net benefit of the policy depends largely on the existence of positive ‘heritage effects’ and acknowledgement from homeowners that policy contributes to neighbourhood stability and the preservation of these positive effects. Our results of a mixed-method analysis of close to 1 million property transactions near to about 8000 CAs and 111 interviews with residents in nine representative CAs in Greater London suggest that positive heritage externalities exist and that residents in CAs tend to value their local environments, acknowledge the need for planning control, and execute their right to object to neighbour's planning request
