The presence of underground quarries in North France in close proximity to urbanized areas, imposes serious problems in terms of security of both people and constructions at one hand, and induces a strong constraint against planning and urban development on the other hand. The purpose of this paper is to provide a practical tool for the preliminary estimation of the stability of underground quarries.

In this paper, a numerical stability study of quarries, excavated in chalk of North France with or without joints, by the method of rooms and pillars, is presented. This integrates the data provided from site: mechanical properties of the chalk and geometric characteristics of the quarries (width of the pillar W, height of the pillar H and span between pillars L), as well as the orientation of the joints (α). Numerical parametric analysis is conducted using FLAC 3D. Factors of safety are computed from the numerical models. Then, a second-order regression technique is applied on these numerically obtained factors, to correlate new formulae.

As a result, user-friendly formulae for the calculation of factors of safety Fs (ex) are extrapolated. Besides, abacuses to determine the minimum permissible effective width of safe pillars are proposed.

By this, it becomes possible, knowing only few parameters about geometry and properties, to give a fast estimation of the stability state of any quarry in the region.

This paper considers vernacular roofing practices for natural slate within the Lake District National Park and looks at the application of traditional techniques within the environmentally‐sensitive area. The paper examines the geology of the Lake District, slate production, methods of re‐slating and specific techniques and details. The paper uses case studies of recent roofing projects to illustrate good practice.

Cleaning metals used in helicopter manufacture. As a result of a search for a generalised method of cleaning metals used in helicopter construction, and which would be safe in all areas, Westland Helicopters Ltd, Yeovil, now uses two Oakite cleaners throughout the factory. Both are alkaline and are supplied in bulk by Oakite Ltd. Both have had to meet stringent AQD approved internal specifications for metal treatment which include requirements that chemical reaction with, or attack by, the cleaner on the metal surface and that tolerances of 0.0001 inch (0.025mm) must be maintained, especially on magnesium.

This chapter will examine two questions. First, how can art and cultural heritage contribute to the health and well-being of a place within the context of the tourism industry? More specifically, can cultural tourism be a driver for community sustainability, that is, not only environmental sustainability but also social empowerment, cultural preservation, and economic vitality? To explore these questions, the author begins by establishing the ways art and environment are closely intertwined, while pondering how cultural production generally – along with the cultural tourists it attracts – can be a driver for sustainability in tourism settings. The benefits that the arts draw from the environment as well as the ways the environment benefits from the arts will be examined. In the next section, the author unpacks how cultural tourism, and more specifically art production, can be drivers for environmental sustainability through social and eco-entrepreneurship and the creation of a shared social value. In the third section, the author identifies some of the challenges inherent in government regulation and preservation of cultural heritage sites. The author argues that communication, cooperation, and relationship building, not just between governing bodies and private stakeholders, but with residents and tourists, should be prioritized in destination management and marketing strategies. In the end, the author proposes that this type of strategy is vital in order to move toward greater cultural, environmental, social, economic, and other kinds of sustainability in the tourism industry.

This paper aims to examine the barriers to the environmental sustainability practices of large-scale mining companies throughout a mine lifecycle, analysed in the context of the plural and competing logics and tensions in the broader institutional environment.

The paper used a qualitative methodology based on multiple cases involving multinational mining companies, regulators and other major stakeholder groups, as it offers an opportunity for analytical generalisations where the empirical results are compared to previously established theories.

The empirical results indicate that the environmental sustainability barriers are embedded within gaps in Ghana’s natural resources governance framework. The gaps arise out of contradictory interests and values, which hinder the direction and practices of large-scale mining companies.

The findings may only apply to the context of this study and is inadequate as the basis for assessing the effectiveness or otherwise of specific initiatives of large-scale mining firms in Ghana.

This study have implications on how large-scale mining companies and their stakeholders define their values and goals, and engage in a dynamic process to accommodate the multiple and competing logics by implementing effective structures at the organisational and institutional levels.

This paper contributes to the sustainability and institutional complexity perspective by showing that plural logics are often contradictory, but may also be complementary in situations of complicit commonality, hindering sustainable outcomes. The authors argue that this is one of the few studies that have examined the barriers to environmental sustainability explicated in the context of institutional complexity.

Knight's Industrial Law Reports goes into a new style and format as Managerial Law This issue of KILR is restyled Managerial Law and it now appears on a continuous updating basis rather than as a monthly routine affair.

Drawing from the institutional logics and organizational disaster literature, this paper aims to illustrate that the replacement of logics can be problematic in a high-risk industry such as coal mining by adding an institutional perspective to the understanding of disasters.

This paper investigated the field of coal mining in Turkey historically from archival data resources. A comprehensive, qualitative inquiry of a single-case study was then conducted.

The findings suggest that a shift from social welfare logic to business logic in the coal-mining industry can lead to coal-mining disasters, resulting from changing practices through an increase in the number of private enterprises through royalty contracts, the use of an increased labor force instead of mechanical methods and systems and the maximization of profit by underestimating the effects of taking almost no occupational safety measures.

The connection between institutional logics and organizational disasters could lead institutional actors to question their understanding of institutional logics.

This paper provides original research evidence for the relationship between industrial disasters and institutional logics.

Despite increasing recognition of the importance of mental health at the workplace, there is very little evidence and limited research information on the issue of the poor mental health of the workers, especially miners. The purpose of this paper is to assess the relationship between stress faced by quarry workers in consonance with their socio-demographic characteristics and their working conditions.

This study was a cross-sectional study of quarry workers with comparison groups in the Karauli district of Rajasthan, a state located in north-western India. The study was conducted during the period May-September 2014, as part of a doctoral program. The study sample comprised a total of 218 quarry workers along with a comparison group of 203 non-miners. The level of occupational stress was assessed by using a General Health Questionnaire consisting of 12 questions.

This study found that the comparison group was at a low risk of psychological stress as compared to the mine workers. The independent risk factors for occupational stress among workers were illiteracy, gender (female), married, divorced/separated, and suffering from some occupational health problem.

This study concluded that mine workers are at a high level of stress, which underscores the need for urgent interventions from the government to address the issue. This is especially important as mine workers make significant contributions to the national income.

This paper fulfills an identified need to study the mental health status of quarry workers, thereby helping fill a persistent gap in Indian research on this issue.

The article examines the trends in the employment of women in the industries and service sectors in India, their conditions of work and their problems.
