Abstract
Life‐cycle analysis (LCA) provides a general framework for assessing and summarizing all of the information important to a decision. LCA has been used to analyze the desirability of replacing lead (Pb) with a composite of tungsten (W) and tin (Sn) in projectile slugs used in small arms ammunition at US Department of Energy (DOE) training facilities for security personnel. The analysis includes consideration of costs, performance, environmental and human health impacts, availability of raw materials, and stakeholder acceptance. Projectiles developed by researchers at Oak Ridge National Laboratory (ORNL) using a composite of tungsten and tin are shown to perform as well as, or better than, those fabricated using lead. A cost analysis shows that tungsten‐tin is less costly to use than lead, since, for the current number of rounds used annually, the higher tungsten‐tin purchase price is small compared with higher maintenance costs associated with lead. The tungsten‐tin composite presents a much smaller potential for adverse human health and environmental impacts than lead. Only a small fraction of the world’s tungsten production occurs in the USA, however, and market‐economy countries account for only around 15 per cent of world tungsten production. Concludes that stakeholders would prefer tungsten‐tin on the basis of total cost, performance, reduced environmental impact and lower human toxicity. However, lead is preferable on the basis of material availability. Life cycle analysis clearly shows that advantages outweigh disadvantages in replacing lead with tungsten‐tin in small‐caliber projectiles at DOE training facilities. Concerns about the availability of raw tungsten are mitigated by the ease of converting back to lead (if necessary) and the recyclability of tungsten‐tin rounds.

Abstract
Given the enormous scope of the decontamination and decommissioning (D&D) work that government and industry face, there is a tremendous opportunity to save money and avoid further insults to the environment and to human health by applying the principles of life cycle analysis (LCA). An LCA approach is presented that is especially valuable in D&D decision making because it provides a systematic, comprehensive, defensible decision‐aiding process to find solutions that reduce costs and risks of D&D projects. Our approach to LCA differs from other approaches by taking into consideration all the factors important to owners and stakeholders – life cycle cost, health and safety, the environment, programmatic impacts, and other factors. Stakeholder participation is also a key part of the process. The result is robust, durable solutions for even the most complex D&D project. A specific demonstration of this approach to aid D&D at two US Department of Energy sites is presented.

Abstract
Purpose
The purpose of this paper is to look at the impact of social exclusion on mental health in Gypsy, Roma, and Traveller (GRT) communities and make suggestions for services needed to address it. The context of significant financial cuts in public sector budgets in the UK and change in the commissioning landscape mean there are significant risks of these vulnerable communities falling even further behind.
Design/methodology/approach
The authors, both currently engaged in clinical practice, draw on mental health and social work perspectives to review key areas in which social exclusion impacts on the life chances of members of GRT communities. Some examples of good current provision are included as is a case study which illustrates the problematic social context in contemporary relations between traditional Gypsy/Travellers and the settled community, and the impact on family life.
Findings
Research findings from contemporary studies are cited, which show members of these communities suffer significant inequalities in all health and social spheres.
Research limitations/implications
The GRT communities have not been listed in census categories until this year (2011).
Social implications
The paper will hopefully contribute to raising public awareness, and support members of the community in participation in policy and decision making.
Originality/value
This paper arises out of interdisciplinary collaboration between a psychiatrist and a social worker with the support of the voluntary sector. The discussion highlights the gaps in commissioning arrangements and hitherto poor support for health and social care needs of the GRT communities.

Abstract
Purpose
Higher education institutions are centers for knowledge creation and transfer, but most are not considered effective learning organizations, as their knowledge resources are not highly used. Therefore, the purpose of this paper is to investigate the moderating role of organizational learning on the relationship between employee participation and academic results in higher education institutions to promote learning in such organizations.
Design/methodology/approach
Data collected from 1,050 faculties and managers at 139 Vietnamese universities were aggregated and used for analysis. Confirmatory factor analysis and hierarchical multiple regression techniques were applied to test the moderating role of organizational learning in the relationship between employee participation and academic results.
Findings
The results provide support for the view that organizational learning positively moderates the relationship between employee participation and academic results in higher education institutions.
Originality/value
The paper explores the concept of organizational learning in the higher education context and clarifies its moderating role to enhance Vietnamese university performance through learning.

Abstract
This paper considers the determinants of residential values from a hierarchical approach based on market experience using a system of Likert Scaling. The approach is tested initially by statistical methods based on a stepwise selection in an ordinary least squares model. The results, however, seem to indicate the presence of multicollinearity, and ridge regression is used to screen the variables and to help select the appropriate model. The study was carried out in Singapore in relation to the rental value of a cluster of 114 high rise apartments in the prime Orchard Road area. The data were collected by Yeo Swee Ching, and both he and Lee Hin Tak used them as a basis for their student dissertations under the author's guidance. This paper sets out some of the methodology and findings of the investigations.

Abstract
Environmental engineering is primarily concerned with the application of technology to the urgent tasks of cleaning up our environment. Its practitioners generally attempt to cope with the problems of streams and waterways polluted by sewage and industrial waste, oceans damaged by oil spills and sewage sludge dumpings, air polluted with noxious fumes and land abused by solid waste disposal. But that is not all that they do. The recent energy crisis has sharply brought into focus the need for alternate energy strategies, including energy extraction from solid waste. Under current estimates, the United States will produce approximately 340 million tons of solid waste by 1980. This is equivalent to one ton of solid waste per person per year. The most widely used methods of waste disposal right now are dumping, incineration and sanitary landfill. They are expensive and they cause pollution. Instead, solid waste can be burned to produce steam which can be used for heating or to generate electricity. It can also be converted to pyrolysis gas or oil, which can be stored or transported. It is from this standpoint that environmental engineering assumes considerable importance. A report which presents an overview of the state of the art in this area is the Resource Recovery from Municipal Solid Waste. Other pertinent guides include Energy from Solid Waste, Conversion of Refuse to Energy, Recycling and Reclaiming of Municipal Solid Wastes, Resource Recovery and Recycling Handbook of Industrial Wastes, and Wasteheat Management Guidebook. No project of this nature can be undertaken without government assistance. A description of the activities of the Federal Solid Waste Management Program is available from EPA's Solid Waste Recycling Projects: A National Directory.

Abstract
Purpose
This paper places a college at the centreof a multi-hazard assessment (earthquake, flood and landslide). The college is within a less studied, rural area of Ladakh, North India. Research focusses on a case study (Students Educational and Cultural Movement of Ladakh (SECMOL) College), close to Leh, Ladakh, and extends to incorporate/apply thinking from/to the wider Ladakh region. The approach adopted, centring on the hazard assessment of a single entity/local area, allows a rapid uptake of hazard recommendations within a college environment planning to continue its existence for decades ahead. A sister paper (Petterson et al., 2019) documents the active involvement of college staff and students in the principles of geohazard assessment and the development of student-centric hazard assessments of the college and their home village. SECMOL is a self-sufficient, alternative, college, organised along strong environmentally sustainable principles. The paper aims to discuss these issues.
Design/methodology/approach
This work has adopted different strategies for different hazards. Fieldwork involved the collection of quantitative and qualitative data (e.g. shape and size of valleys/river channels/valley sides, estimation of vegetation density, measurement of sediment clasts, angle of slopes, assessment of sediment character, stratigraphy of floodplains and identification of vulnerable elements). These data were combined with satellite image analysis to: define river catchment character and flood vulnerability (e.g. using the methodology of Collier and Fox, 2003), examine catchment connectivity, and examine landslip scars and generic terrain analysis. Literature studies and seismic database interrogation allowed the calculation of potential catchment floodwater volumes, and the collation of epicentre, magnitude, depth and date of seismic events, together with recent thinking on the return period of large Himalayan earthquakes. These data were used to develop geological-seismic and river catchment maps, the identification of vulnerable elements, and disaster scenario analyses.
Findings
This research concludes that SECMOL, and much of the Ladakh region, is exposed to significant seismic, flood and landslide hazard risk. High magnitude earthquakes have return periods of 100s to c. 1,000 years in the Himalayas and can produce intense levels of damage. It is prudent to maximise earthquake engineering wherever possible. The 2010 Leh floods demonstrated high levels of devastation: these floods could severely damage the SECMOL campus if storms were centred close by. This study reveals the connectivity of catchments at varying altitudes and the potential interactions of adjacent catchments. Evacuation plans need to be developed for the college. Northern ridges at SECMOL could bury parts of the campus if mobilised by earthquakes/rainfall. Slope angles can be lowered and large boulders moved to reduce risk. This work reinforces recommendations that relate to building quality and urban/rural planning, e.g. using spatial planning to keep people away from high-risk zones.
Practical implications
The frequency of hazards is low, but potential impacts high to very high. Hazard mitigation actions include engineering options for hazardous slopes, buildings to be earthquake-proofed, and evacuation management for large floods.
Originality/value
Methodologies undertaken in this research are well-tested. Linkages between disciplines are ambitious and somewhat original. The application of this work to a specific college centre site with the capacity to rapidly take up recommendations is novel. The identification of catchment inter-connectivity in this part of Ladakh is novel. This work complements a sister paper (Petterson et al., 2019) for community aspects of this study, adding to the novelty value.

Abstract
The Czech Republic has a long history of product excellence recognizable in such diverse areas as beer, weapons and shoe manufacture. Moreover, many of the ideas regarded as central to contemporary expression of TQM such as empowerment and primacy of the organization’s human resource are to be found in the 1920s and 1930s speeches and essays of Czech industrialist and organizational behaviorist Tomas Bata. Nevertheless, the Czech Republic faces distinct challenges brought about by the Velvet Revolution ‐ challenges common to many Central and Eastern European nations. Challenges, practices, trends and the future promise of quality in the Czech Republic are discussed.
