Since publication of the 'Encyclopedia of Housing' in 1998, many issues have assumed special prominence within this field and, indeed, within the global economy, global meltdown spurred by the subprime mortgage crisis to name but one. This second edition offers significant updating and expansion

Since publication of the groundbreaking Encyclopedia of Housing in 1998, many issues have assumed special prominence within this field and, indeed, within the global economy. For instance, the global economic meltdown was spurred in large part by the worst subprime mortgage crisis we've seen in our history. On a more positive note, the sustainability movement and "green" development has picked up considerable steam and, given the priorities and initiatives of the current U.S. administration, this will only grow in importance, and increased attention has been given in recent years to the topic.

AbstractDespite widespread State acceptance of the international law governing military use of force across the spectrum of operations, the humanitarian reality in today's armed conflicts and other situations of violence worldwide is troubling. The structure and incentives of armed forces dictate the need to more systematically integrate that law into operational practice. However, treaty and customary international law is not easily translated into coherent operational guidance and rules of engagement (RoE), a problem that is exacerbated by differences of language and perspective between the armed forces and neutral humanitarian actors with a stake in the law's implementation. The author examines the operative language of RoE with a view to facilitating the work of accurately integrating relevant law of armed conflict and human rights law norms. The analysis highlights three crucial debates surrounding the use of military force and their practical consequences for operations: the dividing line between the conduct of hostilities and law enforcement frameworks, the definition of membership in an organized armed group for the purpose of lethal targeting, and the debate surrounding civilian direct participation in hostilities and the consequent loss of protection against direct attack.

AbstractModern armed forces are employed in a wide array of operations that range from peacetime riot control to outright international armed conflict. Classifying these various scenarios to determine the applicable international law is rendered difficult by both the lack of clarity inherent in the law and the political factors that tend to enter the decision-making process. The author describes the major challenges of legal classification facing the military leadership, and proposes a solution to ensure that the intended beneficiaries of the law – from soldiers to civilians – do indeed receive its protection.

Abstract
Thermal desorption (TD) gas chromatography is a widely used analytical method for measuring airborne concentrations of (semi) volatile organic compounds ((S)VOCs) collected using sorbent tube samplers and is now widely used in the ambient, fence line, indoor and workplace air monitoring environments. Calibration and internal quality control check samples are prepared in end user laboratories by spiking individual TD sorbent tubes with microliter quantities of (S)VOCs in a carrier solvent such as methanol but this can be a laborious and error-prone step. Historically spiked sorbent certified reference materials were available from IRMM for confirmatory purposes but these stocks are now virtually exhausted. Hence new spiked tubes would be useful for quality control/assurance purposes. Previously HSE developed a system for the simultaneously spiking of 60 TD sorbent tubes with defined mases of VOCs from the gas-phase based upon requirements set out in ISO 6145 part 4[1]. With less volatile (S)VOCs however, spiking from the gas-phase presents challenges and hence an alternative spiking approach using liquid standards is proposed. The performance of a newly acquired automated robotic spiking system will be described.

This article presents the first systematic analysis of residential satisfaction ratings from the largest consumer comment Web site for U.S. apartment residents, www.ApartmentRatings.com. Using the 464,281 tenant satisfaction ratings posted from January 1, 2000, to January 1, 2007, we examine the relative importance of seven core factors in determining tenant satisfaction: parking, noise level, landscaping, safety, building construction, office staff, and maintenance service. Cross tabulation, ordered logit, probit, and path analysis models all point to tenant relations with management office staff as the most influential factor in tenant satisfaction. The fact that the manager—tenant relationship exists for tenants but not for homeowners may help to explain why the gap in residential satisfaction between owners and renters persists even when controlling for other physical environmental characteristics.

Abstract
Silicosis, one of the oldest recorded occupational diseases, is a form of lung disease caused by the inhalation of respirable crystalline silica (RCS) within occupational settings such as quarrying, foundries, potteries and stone masonry. Hence worker exposure studies, involving sampling airborne dust onto a filter for subsequent silica analysis in the laboratory, are often conducted. Laboratories use either X-ray diffraction (XRD) or Fourier-Transform Infrared (FTIR) spectroscopy for measurements and follow validated procedures set out in either national regulatory methods or in international consensus standards. But how well do these published methods work in routine occupational hygiene laboratories? The AIR proficiency testing (PT) programme, a partnership between HSE and LGC Standards, offers test items where participants receive samples prepared through the aerosolisation of defined masses of quartz onto air filters. Are there differences between laboratories using direct on filter assays and those that use methods which require a sample preparatory step? Are instrumental measurements by XRD and FTIR comparable? In this presentation, we will attempt to answer these questions using returned PT data.
