Scaringella, Jean-Louis. "Les industries de defense en europe : aspects juridiques et economiques." Paris 11, 1995. http://www.theses.fr/1995PA111013.
Full textAbstract:
Depuis la fin de la seconde guerre mondiale, les pays europeens ont developpe des industries d'armement qui ont aujourd'hui un poids economique considerable, tant du point de vue de leur chiffre d'affaires que des effectifs employes. Elles sont fortement exportatrices, grace a la large gamme de leurs productions dans tous les domaines de la defense. Elles sont tres lourdement frappees par la crise qui met en evidence leurs surcapacites et leurs sureffectifs. Leur cadre juridique demeure encore lacunaire. Il presente notamment des reglementations heterogenes en matiere de regime des exportations. Le secteur de l'armement, ecarte du champ d'application du traite de rome, releve essentiellement des reglementations nationales. Les industries de defense ont developpe des cooperations au niveau europeen tant bilaterales que multilaterales. Ces cooperations trouvent leur cadre institutionnel dans les relations interetatiques. Elles font egalement appel aux instruments du droit commercial des differents pays. Mais les cooperations europeennes sont encore tres limitees, alors que le nouveau contexte economique et strategique rend leur developpement indispensable. La reduction drastique des budgets de defense appelle une politique industrielle au niveau de l'union europeenne. Pour favoriser la politique de cooperation, un cadre juridique europeen devient necessaire, tant pour structurer les relations entre etats que les actions entre industriels. La creation d'une agence europeenne de l'armement apparait souhaitable, de meme que l'evolution de la reglementation europeenne en matiere de concurrence pour rendre plus faciles les alliances et les concentrations

Full textAbstract:
Recent studies of the environmental Kuznets curve raise questions regarding the relationship between environmental indicators and GDP and the fundamental reasons that explain this relationship. In response, this thesis presents one-sector and two-sector models to analyze the alternative causal relationships between an environmental indicator and GDP at different stages of economic development. These models analyze how economic scale, technology, preferences, and economic structure influence the causality and shape of the relationship. These theoretical studies are followed by two empirical studies. The first tests the causal relationship between CO2 emissions and GDP in Canadian manufacturing industries. The second explores several factors as the fundamental causes that influence the CO2 emissions in the same industries. Factors, such as economic scale, preferences, technological progress, structural change, and energy input, are found to be crucial in the determination of CO2 emissions. The empirical results are positive, but there are data limitations. The empirical studies can be re-evaluated as more data becomes available.

Full textAbstract:
I consider the influence of foreign environmental policy on domestic manufacturing activity using theory and empirics. A tractable three-country spatial model yields a theory of locational com- parative advantage in the production of pollution-intensive manufactured goods: greater market access to countries with stringent environmental policy encourages output in the polluting sector. Operationalizing the model empirically, I find robust evidence that high market access to countries with stringent environmental policy increases manufacturing value added. Both the theoretical and empirical analyses suggest that estimates of the Pollution Haven Effect that ignore third country environmental policy - yet make the stable unit treatment value assumption - can be misleading. Chapter Two We investigate the impact of short-term weather and long-term climate on self-reported life satisfaction using panel data. We find robust evidence that day-to-day weather variation impacts life satisfaction by a similar magnitude to acquiring a mild disability. Utilizing two sources of variation in the cognitive complexity of satisfaction questions, we present evidence that weather bias arises because of the cognitive challenge of reporting life satisfaction. Consistent with past studies, we detect a relationship between long-term climate and life satisfaction without individual fixed effects. This relationship is not robust to individual fixed effects, suggesting climate does not directly influence life satisfaction. Chapter Three This chapter considers the related policy challenges of deindustrialisation and 'leakage' which can arise when environmental regulation is differentiated across regions. A dynamic two-region 'New Economic Geography' (NEG) model is adopted in which agglomeration forces may make firms tolerant of regulatory disadvantage. Each region ratifies an international environmental agreement (IEA) requiring it to tax transboundary pollution created by local firms. In contrast to previous NEG studies, the model adopted is considerably more tractable, enabling comparative static analysis to be conducted analytically rather than through computer simulation. The model is extended to consider the relationship between the prescribed tax rates and deindustrialisation caused by the relocation of firms. Firm relocation in response to a given tax differential depends crucially on trade costs and the initial location (configuration) of industry. For some industry configurations, agglomeration forces are strong and a set of tax differentials exist which cause no international relocation of polluting firms. For other initial industry configurations in which agglomeration forces are weaker, the same set of tax differentials may cause complete inter-national relocation to the less stringently regulated region. Trade liberalization can actually make industry less likely to relocate in response to a regulatory disadvantage. The model is further extended to consider the issue of carbon leakage, which arises in the regulation of greenhouse gas (GHG) emissions. For relatively low tax differentials, agglomeration forces create rents which tend to anchor industry in the higher taxing region, avoiding carbon leakage. If the tax differential is too great, however, agglomeration forces cause all firms to relocate to the lower taxing region where they optimally emit more GHGs. Environmental outcomes may therefore be improved by reducing the tax rate in the higher taxing region in order to discourage industry relocation. When industry is diversified between regions, firms respond to higher (lower) relative domestic taxes by increasing (decreasing) output and polluting more (less).

Full textAbstract:
The purpose of this study was to assess the status of worksite smoking policies in Indiana's manufacturing industries and to describe the relationship between policy, workforce size, and manufacturing type. Of the 493 questionnaires distributed, 181 (36.7%) were returned. Approximately 67% percent of the industries reported having some type of restrictive policy with the majority of those policies not allowing smoking at the worksite except in designated areas. Most policies were developed within the last five years and were implemented due to a concern for employee health. Workforce size was directly related to the prevalence of significant restrictions. Those companies employing greater then 100 employees were the most likely to have a policy whereas the employing less than 11 were the least likely to have a policy. Standard industrial classifications 34 (fabricated metal products) and 35 (machinery, except electrical) had less restrictive policies as compared to other S.I.C. classifications. A follow up on 10% (n=30) of the nonrespondents yielded similar results to those who did respond.Department of Physiology and Health Science

Full textAbstract:
Unplanned and rapid growth of tourism can be perilous to the natural and socio-cultural environment of communities and regions. Unplanned tourism can destroy the unique landscapes upon which it depends. This problem is particularly severe in third world nations which are hosting a new generation of tourism in hopes of economic survival.This paper presents a case study which supports the above contentions by identifying changes that have taken place in Negril, Jamaica, through a discussion of the causes and effects of rapid, poorly planned tourism development in that town. This provides the basic framework within which the author raises questions suggest ideas to promote more appropriate and culturally and sensitive changes in present land use policies in the city of Negril.Department of Landscape Architecture

Thesis (MTech (Business Administration))--Cape Peninsula University of Technology, 2017.This research study investigates how environmental tools such as Resource Efficiency and Cleaner Production (RECP) can contribute to sustaining and supporting economic growth in South Africa. Resource optimisation is crucial when considering the concept of sustainable development. It also contributes to addressing the challenges of global warming and climate change, which in turn threaten industrial growth and sustainability in the long term. The study places emphasis on the barriers that prevent industry from implementing RECP recommendations, and identifies opportunities that could potentially reposition businesses should they consider implementation. It also promotes other sustainability tools that are available through collaboration with international entities, and this could be of great benefit to the South African industry. Factors of unemployment and urbanisation restricts national growth to some degree, hence the study explores how RECP can contribute to job retention by introducing new resource optimisation methodologies for the manufacturing sector, Moreover, it examines the imbalance between the demand as well as limitations of these resources. Through the compilation of data collated from questionnaires completed by industry, government and civil society participants, this study looks at achieving a balance between environmental sustainability and growth. It also looks at aligning this balance with the integration of specific economic and environmental policies, which also includes social aspects. What comes through significantly in this research is the lack of awareness within industry in terms of RECP, as well as the importance of prioritising the uptake of environmental initiatives to ensure that industry is compliant with the stringent policies and legislation designed by government to drive the sustainability process. Consequently the study shows that communication between public and private sector, as well as the awareness raising and marketing of sustainability to consumers need to be improved. An analysis of the various government support mechanisms is conducted, in respect of how industry could potentially leverage growth and drive positive change within their businesses. In addition to RECP, emphasis is placed on other Sustainable Consumption and Production (SCP) initiatives and tools that could possibly entrench sustainable practices and help with their incorporation into their business strategies.

Full textAbstract:
There is a growing concern from government, communities, civil society and mining companies on the sustained development of the impact of mining on communities and the benefits of mineral development. Communities are more vocal in expressing their expectations for benefits and on the other hand mines are concerned about profits and maintaining a social licence to operate. This study critically evaluates the impact mining has on socio-economic development in mining communities. The focus area of the study is the West Rand District Municipality in Gauteng Province, South Africa. The ‘impact’ refers to the mine’s contribution to infrastructure development and poverty reduction projects in areas where the mine is operating and sourcing labour from. Forecasts for better performance in the future will be assessed. Issues such as community consultation, identification of projects, development forums, the Integrated Development Plan (IDP) and partnerships are addressed. The literature was reviewed from existing national and international research on the topic. The study starts from two assumptions. The first is that minerals are potentially a great resource of wealth for poor countries. The second assumption is that minerals have the potential to benefit the local population through the creation of indirect employment, skills transfer, enhancing the capacity of health and education services, improved infrastructure and small and medium business opportunities. Poverty levels are viewed on a national and international scale. The study reveals problems, with existing approaches, on mine community development. It concludes that the impact of mining on infrastructure development and poverty reduction projects can be huge, but only if a variety of demanding preconditions are met. The study concludes that the reality of mineral led development in mine communities has not lived up to a roaring promise.

Full textAbstract:
Energy is essential to economic prosperity and quality of life. However it can have detrimental effects on the environment if not used properly. Moreover, if energy resources are scarce in a given country, then its use will impose economic and financial burdens on the national economy. The cement industry is energy-intensive, which adds a micro dimension to the macro issues mentioned above. Reducing energy consumption without due consideration to production requirements is not an optimal situation. What is needed is to arrive at a situation whereby energy is used rationally. The concept of rational use of energy has two embedded principles. The first is increased energy-use efficiency and the second is environmental protection. Jordan Cement Factories (JCF), located in a developing country where energy resources are not indigenously available and, therefore, costly energy requirements are imported, have realised the importance of addressing the energy management and conservation issues. This thesis describes the efforts initiated and conducted by the author, to address the research problem of improving energy usage through the application of effective management techniques aimed at reducing energy consumption per unit of cement produced. This present research has been concerned with energy management and efficient use of energy. The Jordan Cement Factories were used as a vehicle to demonstrate the proposed research methodology that aimed at improving energy consumption and thus operational efficiency. The methodology is based on establishing statistically significant relationships between interacting problem factors, and assessing the economic impact of improving these factors. Economic evaluation entailed the development of economic models and an application methodology combined with illustrative case studies. Consequently, the problem of energy management has been presented in a wider perspective that addressed the whole management system at the organisation. Towards that end, it was first necessary to show the significance of energy cost with respect to the overall manufacturing costs. The analysis of production costs, which demonstrated the significance of energy costs, was followed by the investigation and examination of the basic management factors that have direct impact on energy consumption at the JCF. Among these factors are, for instance, production line availability, production rate, average number of stoppages, and average duration of stoppages. These factors were determined using preliminary data analysis and the experience and technical knowledge of the researcher. The statistical analysis proved the existence of strong relationships between energy consumption and management factors. Several models were developed for a set of selected production lines, in the JFC at Fuhais and Rashadiya plants. These statistical models were generated using actual data for electrical energy and fuel consumption. The derived models have demonstrated the existence of strong relationships between energy consumption and management control factors; for instance, the values of R2 range from 60% to 90%. This implies that an equivalent percentage of the variations in energy consumption can be attributed to the selected management factors. The economic model developed in this research is concerned with demonstrating that effective management practices associated with proper maintenance and housekeeping can result in highly significant savings in energy usage. Although a simplistic methodology was used to evaluate the economic impact of any improvement programme, the economic treatment showed that the cost of improvement is actually negligible compared to the realisable savings in energy usage. The research has dealt with the details of developing a coherent energy management model whose objective is to establish transformational management processes of certain high-level management factors into daily operations and controls. The high-level management .factors are the same factors used as independent variables in the statistical and economic models, which statistically proved to be the major factors affecting the energy consumption at JCF. The research has also presented a detailed analysis of the organisational and procedural aspects of energy management with concentration on management functions, especially planning, controlling, executing, organising, and auditing. A detailed mapping and analysis of these functions as the main components of an Energy Management System (EMS) resulted in establishing job descriptions, organisational charts, work instructions and procedures for all-important functions of the EMS. The type of work described in this thesis could be extrapolated for application in other industries, particularly energy-intensive ones, to arrive at the objective of rational use of energy at the national and international levels. Comprehensive studies would need to be carried out for each type of industry prior to implementation. The cost benefit analysis presented in this research proved, beyond any doubt, the importance of implementing the EMS in JCF. As a result of this implementation it is demonstrated that huge annual savings were realised. Finally, as a result of improving energy control factors, introducing energy conservation measures and employing management techniques at JCF to guarantee the effectiveness of all such activities, resulted in an annual savings amount to about USS 3.5 million. Therefore, if the same or similar actions are undertaken by all cement, or other highly energy intensive industries then the savings could reach billions of dollars.

Full textAbstract:
The substantial pollution threat to the South African environment from acid mine drainage (AMD) effluents has been well documented. Due to the juvenile nature of acidity in these flows, any remediation strategies implemented will need to function effectively and at low cost for long periods of time. The widespread use of sulphate reducing biological systems for the treatment of such effluents, and in particular large volume flows, has been limited. The supply of inexpensive electron donor and carbon sources, as well as appropriate reactor designs capable of handling large volume flows, have been identified as among the principal factors limiting development of this technology. The broad aim of the research programme reported here was to undertake an evaluation of the feasibility of an algal-bacterial integrated ponding system for the treatment of AMD, and the waste stabilisation pond (WSP) as an appropriate reactor design for this application. The study attempted to demonstrate the feasibility of individual unit operations in a proposed process train using complex organic carbon serving as the electron donor source for the sulphate reducing bacteria (SRB). Studies were undertaken as laboratory and pilot-scale investigations. Tannery effluent was shown to be a functional carbon source for biological sulphate reduction, with effective removal of sulphate and organics being recorded. In turn, the use of biological sulphate reduction for the treatment of tannery effluent was demonstrated. Algal biomass was shown in laboratory studies to function as an effective carbon source for biological sulphate reduction. It is known that micro-algae produce large quantities of photosynthate which is released to the growth medium under conditions of physiological stress. The potential for the use of photosynthate production in high rate algal ponding systems and its manipulation and use as a sustainable carbon source for sulphate reduction was investigated. Growth of a mixed culture of Dunaliella under conditions of light, temperature and salinity stress demonstrated production of large quantities of organic carbon. However, growth was inhibited at high temperatures. An elevation of salinity levels led to a decrease in growth of Dunaliella, but to increased organic carbon production. Spirulina spp., on the other hand, grew well at higher temperatures but showed the highest organic carbon production, and release to the medium, under low light conditions. These results led to a proposed process for the integration of algal ponding into an integrated system for the treatment of AMD. The algal biomass may be fed into the anaerobic digester as a carbon source, or it may be passed into a High Rate Algal Pond (HRAP) where it is stressed to enhance the organic carbon content. This can then be fed into the anaerobic digester as a carbon source. The impact of high levels of sulphide in the water feeding to the algal growth compartment was investigated. Spirulina spp. isolated from a tannery waste stabilisation pond was shown to be a sulphidophilic strain of cyanobacterium, capable of being adapted to high concentrations of sulphide. Dunaliella salina on the other hand was less tolerant. These results demonstrated the practical use of algal biomass providing an oxygen-rich cap for odour control on the surface of the facultative pond as well for the secondary treatment of sulphide-rich overflow to the High Rate Algal Pond. The ability of micro-algae to elevate the pH of their surrounding environment was evaluated as a functional precipitant and neutralisation reagent for acidic metal containing wastewater. Spirulina spp. was shown to perform effectively. D. salina was less functional in this environment. Anacystis spp. was effective in elevating the pH of a defined medium as well as a zinc-rich effluent. These results indicated the practicality of a neutralising function for algal ponds in the treatment of AMD. Metal removal in the system was found to be a combined function of sulphide precipitation, removal by binding to micro-algal biomass and extracellular polymeric substances. The feasibility of waste stabilisation ponding technology use for the treatment of large volume AMD effluents was provisionally demonstrated. It was shown that complex carbon sources would be used as efficient electron donors for sulphate reduction. The integration of algal ponding into the system provides for the generation of a sustainable carbon source, odour control with the recycling of oxygen-rich water onto the top of the facultative pond, secondary treatment of the anaerobic digester overflow, and the neutralisation of the incoming acidic effluents and removal of heavy metals. Integration of the individual unit operations, the feasibility of which has been provisionally demonstrated in this study, into a continuous process train is being investigated in follow-upstudies.

Full textAbstract:
This study develops and tests a methodology that can be utilized for a reconnaissance level assessment of electric power supply alternatives for medium-scale mining in northwestern British Columbia.
The study is organized into four parts.
Part one characterizes the public planning framework of the study area. Present and future use trends of the region's natural resources, in particular minerals and energy, are reviewed, and a typology of public preferences for their development is established.
Part two carries out a literature-based review of the conceptual basis of normative decision-making. Specific energy project evaluation approaches are introduced. This establishes a theoretical framework for constructing the methodology.
Part three presents the energy project assessment methodology.
Part four applies the methodology to the RED-CHRIS deposit.
Salient features of parts three and four which form the core of the study, are outlined below.
Energy Project Assessment Methodology
The central part of the study proposes a strategic, reconnaissance-level methodology for evaluating energy supply alternatives for medium-scale mining. Its scope is defined by; a) inclusion of strategic elements such as emphasis on priorities, analytical continuity, robustness, and adaptiveness, and b) adoption of a reconnaissance approach which reflects
an intention to accommodate preliminary information at an appropriate level of complexity and comprehensiveness.
The essence of the methodology entails three inter-related components:
1) Core Information Environment - Identifies and focuses on defining the energy supply issues for a particular undeveloped mineral deposit.
2) Basic Evaluation Environment - Assesses the viability of potential alternatives through the application of multiple criteria and formal decision-making procedures.
3) Peripheral Evaluation Environment - Assesses strategic information which is independent of the focused problem, but can exert an influence on the outcome of both the core and basic environments.
Each component contains strategic data bases and analytical processes that assist the analyst to proceed from initial problem identification to selection of alternatives. Within and between the three structural component information is refined in an iterative fashion. This maintains a current perspective on the problem environment and leads to a more confident appraisal of the favoured energy alternatives for a mineral deposit.
Case Study Analysis:
RED-CHRIS copper-gold deposit situated southeast of Iskut was selected for a case study application of the methodology. Typical production schedule ranging from 8 to 20 years would require corresponding installed electrical capacity of 7.5 to 23.5 Megawatts.
Key points which emerged from an analysis of this deposit's energy supply alternatives form the mine planner's perspective are:
1) Interest groups concerned with planning, developing, or regulating energy supply for RED-CHRIS include:
a) Mineral deposit owners whose objective it is to maximize profit b) Societal interests whose objective it is to maximize economic, social and environmental well-being aspects of the project.
c) Public policy interests whose objective it is to maximize economic, political, and social welfare within national and provincial energy policy.
2) Energy supply candidates identified and examined, include: diesel-electric, high voltage grid extension, small-hydroelectric, coal and biomass-fired generation, natural gas, peat, geothermal, wind and solar.
3) Comparison of different small-scale energy applications for remote areas is made difficult because of technical, political, and environmental uncertainties.
4) Satisficing and Dominance can be successfully applied from the mine planner's perspective to key decision criteria to narrow the various energy supply alternatives.
5) Small-hydro is the most favourable alternative at this juncture, followed by diesel. Coal-fired generation and biomass are comparable, and may be more favourable than diesel under certain circumstances. Other alternatives are presently unsuitable.
General Conclusions: Application of the methodology is limited by the interaction between analytical design, available physical resources, and uncertainty in the operating environment, human values and external decisions.
The methodology appears sufficiently robust and comprehensive to be adapted to other deposits in the region. Commonly shared information requirements combined with the iterative nature of information processing, can be used to reduce the resource demands and improve the efficiency of subsequent applications. Finally, it is recommended that the value sensitivity of the methodology be tested by applying it from more than one perspective to the same deposit.Applied Science, Faculty of

Full textAbstract:
Greenhouse gases (GHGs) are vital components of the earth�s atmosphere, trapping heat around the earth, maintaining temperatures necessary for human existence. Until the Industrial Revolution, these gases existed in a natural equilibrium with the environment. Since that time, anthropogenic activities such as fossil fuel burning and land clearing have increased the quantity of GHGs, such as carbon dioxide (CO2) and methane (CH4), in the earth�s atmosphere. Evidence indicates that global warming is occurring as a result of the additional accumulation of GHGs in the atmosphere.
International response to climate change resulted in the 1997 development of the Kyoto Protocol. If the Protocol is ratified, developed countries will be legally bound to reduce their GHG emissions in accordance with negotiated emission reduction targets. At the beginning of the year 2001, the Protocol was still to be ratified.
With the possibility of future GHG emission restrictions, some Australian companies have started quantifying their GHG emission levels. One such company is Visy Industries, the largest privately owned paper packaging manufacturing company in the world. Visy�s core business is the manufacture of cardboard boxes from recycled paper. As part of its future operations, a kraft pulp and paper mill is presently being built in New South Wales, Australia.
The environmental decision support tool, Life Cycle Assessment (LCA), was used to quantify Visy�s CO2 and CH4 emissions across the entire life cycle of the Visy paper recycling and virgin papermaking processes. Commercially defined LCA models were developed for both papermaking processes.
GHG emissions estimated by each model were compared and the effect of different energy sources, technologies and manufacturing processes on CO2 and CH4 emissions were assessed. The majority of emissions in the two Visy papermaking models were due to fossil fuel derived energy sources and the decomposition of wood fibre in Solid Waste Disposal Sites (SWDSs). Results were used to propose appropriate GHG reduction strategies and business opportunities.
GHG reduction strategies included increasing the use of renewable energy, reducing the volume of solid waste rejects sent to SWDS, incinerating solid waste rejects with energy recovery and sourcing steam from third party providers. Proposed GHG business opportunities included increasing the production of Greenpower from the pulp and paper mill for sale to the grid.
This thesis is an example of the practical application of current GHG knowledge and LCA methodology that was undertaken in an environment where technical, political and commercial guidelines at both a national and international level were still evolving. Nevertheless, the thesis is not a critical review of LCA methodology.
The LCA support tool was able to quantify CO2 and CH4 emissions across the life cycle of the Visy recycling and virgin papermaking processes. The chosen functional unit, the assumptions and exemptions made, and the placement of the system boundaries, were found to be critical to the Visy LCA results.

Thesis (MMil)--Stellenbosch University, 2003.ENGLISH ABSTRACT: The fundamental motivation for emerging arms suppliers to produce arms was the desire to overcome their position of dependence in the system of arms production and transfers. However, their predicament as late entrants into the system castigated them to fail in this endeavour. This failure is based on three criteria, which also assist in the identification of emerging suppliers. Firstly, the weaponry they produce is far below the sophistication characterised by higher levels of technological advancement. Secondly, they can only produce one or two advanced weapon systems. Finally, they rely on the leading suppliers for certain sophisticated components of weapon systems which they cannot produce themselves and as a result, become so dependent that they, with an exception of a few, are unable to go beyond the simple reproduction or retrofitting of existing weapon systems. The capability to produce arms was restrictedly extended to certain states in the post-war era, and even those states that obtained such a capability were confmed to producing small arms and platforms for naval vessels. Those states that went beyond these capabilities did so with the assistance of other states or specialists, the initial intention being to meet domestic requirements, and ultimately to dispose surplus Second World War equipment in the re-transfer market. The emerging supplier states' intention to develop indigenous arms industries was driven by the political urge to reduce their reliance on the leading suppliers and to nationalise the arms production process for import substitution in order to meet domestic security needs. Since the emerging suppliers began the process of defence industrialisation from the importation of complete weapon systems to import substitution, and ultimately to the promotion of exports, they mainly relied on technology imported from the leading suppliers. On the one hand, the leading suppliers attempted to hinder the efforts of emerging suppliers to promote arms exports so as to protect their oligopolistic share of the arms market through tightening the controls and regulations on technological supplies. On the other, the emerging suppliers were impelled to promote their arms exports in order to overcome the saturation of their domestic markets, to utilise effectively their arms production capacities, and to positively affect their balance of payments through the procreation of foreign exchange returns. This study reached the following conclusions and inferences: 1. The arms trade has evolved to be characterised by the transfer of military technology, which did not feature in the arms transactions of the previous periods. 2. The gap between the leading and emerging suppliers is widening with regard to the sophistication of technological capabilities, and accordingly the stratification within the arms production and transfer system is sustainable and reinforced, thus making it hard for the lower tiers to progress beyond their current status. 3. The emerging suppliers' share of and contribution into the arms market is constricted, and as such they specialise in specific (often uncomplicated) weapon systems that constitute niches in the global market. 4. The unfolding arms production and transfer system is characterised by a fiercely competitive atmosphere, and consequently, only those states that can subsidise or integrate their efforts are enabled to sustain an advanced arms production faculty. 5. As the emerging suppliers begin to introduce more and more of their wares into the market, the costs of research and development begin to soar in the same manner as those of the leading suppliers, thus urging them to become more export-oriented. 6. Participants in the system will be compelled to relinquish their comparative technological superiority in order to survive, thus narrowing the gap between the capabilities possessed by both the leading and the emerging suppliers.
AFRIKAANSE OPSOMMING: Die onderliggende motivering van opkomende wapenverskaffers om wapens te produseer word toegeskryf aan 'n behoefte om hulle relatiewe afhanklikheid in die stelsel van wapenproduksie en - handel te oorkom. Boonop het die laat toetrede tot die stelsel hierdie opkomende verskaffers se kanse tot sukses verder belemmer. Die rede vir die onsuksesvolle toetrede word gebasseer op drie kriteria (wat ook dien as identifiserende eienskappe van opkomende wapenverskaffers). Eerstens, die wapens wat opkomende verskaffers lewer skiet tekort aan die vereiste gesofistikeerde standaarde van die gevestigde wapenprodusente. Tweedens, hulle kan slegs een of twee gevorderde wapenstelsels produseer. Derdens, sekere komponente van wapenstelsels word verkry by die gevestigde verskaffers, wat lei tot afhanklikheid tot so 'n mate dat die opkomende verskaffer se vermoëns beperk word tot eenvoudige reprodusering of herinstallasies van bestaande stelsels. Trouens, in die post-oorlog tydperk is die vermoë om wapens te produseer doelbewus beperk tot sekere state wat 'n afgebakende reeks van handwapens en uitrusting vir vloot vaartuie kon vervaardig. State wat verby hierdie vermoë beweeg het, het dit gedoen met behulp van ander state of spesaliste, oorspronklik met die oog op die huishoudelike behoefte maar ook om ontslae te raak van surplusse uit die Tweede Wêreldoorlog. 'n Politieke begeerte om in hulle eie sekuriteitsbehoeftes te voorsien deur middel van invoersubstitusie, het die opkomende verskaffers genoop om ontslae te raak van die afhanklikheid op gevestigde verskaffers en om die wapenproduseringsproses te nasionaliseer. Hulle het hoofsaaklik gesteun op ingevoerde tegnologie om die verdedigingsbedryf te industrialiseer. Die proses het so verloop: volledige wapenstelsels is ingevoer, daarna het invoersubstitusie plaasgevind, en daarna 'n bevordering van uitvoere. Gevestigde verskaffers het endersyds probeer om (deur middel van strenger kontrole en regulasies of tegnologiese ware) die opkomende verskaffers te verhoed om hulle oligopolistiese houvas op die mark te belemmer en andersyds moes opkomende verskaffers noodgedwonge hulle uitvoere bevorder om te voorkom dat die plaaslike mark versadig word. Die laasgenoemde aspek het ook die betalingsbalans van opkomende verskaffers positief beinvloed as gevolg van die inkomste uit buitelandse valuta. Hierdie studie kom tot die volgende aanames en gevolgtrekkings: 1. Wapenhandel het só ontwikkel dat die oordrag van militêre tegnologie die hoofkenmerk geword het in die stelsel - 'n ongekende kenmerk tot dusver in die ontwikkelingsgang van internasionale wapenhandel. 2. Die gaping van tegnologiese vermoëns tussen opkomende en gevestigde wapenverskaffers word groter en daarmee saam word die stratifikasie in wapenproduksie en -lewering volhoubaar en versterk, wat lei tot 'n beperking op die vermoë van opkomende verskaffers om vooruitgang te maak. 3. Opkomende verskaffers se aandeel in en bydrae tot wapenmarkte bly beperk en spesialiseer daarom op spesifieke (meestalongekompliseerde) wapenstelsels wat gemik is op sekere nisse in die wêreldmark. 4. Die ontluikende wapenproduksie en -handelsisteem is uiters kompeterend, met die gevolg dat slegs state wat hulle pogings kan subsidieer of integreer in staat is om gevorderde fasiliteite te onderhou. 5. Met die toenemende aanbod vanaf opkomende verskaffers, styg die kostes van navorsing en ontwikkeling vir beide die opkomende en die gevestigde verskaffer wat weer beide dwing om hulle uitvoere te beklemtoon. 6. Deelnemers in die stelsel sal gedwing word om hulle vergelykende tegnologiese voorsprong prys te gee om te oorleef in die stelsel, waarna die gaping tussen die vermoëns van opkomende en gevestigde verskaffers verminder sal word.

Full textAbstract:
Extended producer responsibility (EPR) as a holistic approach to product stewardship has been increasingly incorporated into environmental policy agenda in the last two decades. One major expectation of EPR is to prevent environmental problems at source by providing appropriate incentives for product eco-design changes. However, available studies empirically examining the actual influence of EPR on eco-design are limited. This research therefore aims to fill the research gap by evaluating the effectiveness of existing EPR programmes in driving eco-design changes from the perspective of China’s electrical and electronic (EE) industry, and shed some light on the prospects of EPR development in China.
Based on the analytical framework developed from reconstructed intervention theory, three intensive empirical studies have been carried out. The first study examines the perception and responses of 50 China’s EE manufacturers regarding the EU EPR programmes (i.e. the WEEE and RoHS Directives). The second study investigates the responses of 36 China’s EE manufacturers to the Chinese EPR programmes (i.e. China WEEE and China RoHS legislation) and identifies possible factors that exert causal impact on the occurrence of eco-design. In order to gain a deeper insight into the practical manifestations of effective EPR implementation in the private sector, three company case studies have been conducted in the third stage of the research, serving as an important supplement to the first two studies.
The three studies show that EPR programmes in a stringent regulatory approach focusing on products’ environmental properties such as substance bans can exert strong influence on design changes. However, mandated recycling legislation seems to have little driving effect for companies to change product design. The research points to the weakness of collective producer responsibility that is currently adopted in many EU Member States for WEEE implementation in achieving continuous eco-design improvements. It highlights the significance of realising the principle of individual producer responsibility in EPR programmes for achieving this goal.
Based on an attributability assessment, the research further shows that there are a number of factors that influence the adoption of eco-design in China, and the link between legislative EPR programmes and eco-design is complex and evolving. Not only may the EPR programmes have different existing, anticipating and potential effect on the incorporation of eco-design, but they may have very different driving influence on environmental laggards and leaders.
In this regard, this research suggests that there is no one-stop solution for EPR in China. A mixed mechanism that integrates various policy instruments such as administrative, economic and informative instruments, in conjunction with cooperation and infrastructure facilities, would be the most effective means to implement EPR in the context of China, thereby achieving the goal of sustainable production and consumption.published_or_final_version

Thesis (MTech (Business Administration))--Cape Peninsula University of Technology, 2018.The oil industry has been a major contributor to economic development in many countries; providing jobs, revenue, infrastructure and businesses to third parties. However, this development has also come with adversity on the physical environment. The oil industry accounts for the highest Green House Gas (GHG) emissions in the world, making it the number one polluter. In addition, South Africa has been regarded as the biggest polluter in Africa, with fossil-based fuel cited as the major cause of environmental degradation. South Africa’s physical environment is also cited as having degraded more than most countries in Africa. This proposition requires players in the oil industry to urgently address this situation. As the future of economic development is likely to be spearheaded by the oil industry, concerns have been raised at the slow rate of addressing oil companies’ operations which causes the environment to be less sustainable. This study uses a qualitative content analysis to explore the oil companies’ actions towards addressing environmental adversity caused by their unsustainable operations. In order to be environmental sustainable, oil companies must; incorporate environmental sustainability into missions and visions, financial investment into sustainable initiatives, involve top management in environmental programs, engage stakeholder, comply and align organisational processes and operations with environmental legislations and introducing renewable energy.

Full textAbstract:
Fundação Araucária; CAPESAs indústrias alimentícias utilizam considerável volume de água para suprir a demanda de processos. Devido a isso, observa-se um grande volume gerado de efluentes que necessitam ser tratados para garantir o destino final adequado. Tendo em vista a crescente escassez de água, procedimentos de racionalização do uso da água e o reúso de efluentes tratados surgem como soluções para estes problemas. A aplicação de processos de separação por membranas no tratamento de efluentes da indústria alimentícia para reúso apresenta-se como um processo de tratamento avançado apropriado. Deste modo, o objetivo deste estudo foi avaliar a utilização dos processos de separação por membranas como tratamento avançado de águas residuárias agroindustriais provindas de um abatedouro e frigorífico de suínos, da região oeste do Paraná, visando à possibilidade de reúso destes efluentes. Para isso, foi necessário: realizar a caracterização físico-química dos efluentes agroindustriais; avaliar o emprego de microfiltração, ultrafiltração, e microfiltração seguida de ultrafiltração em diferentes condições operacionais de pressão aplicada à membrana, e avaliar a qualidade do efluente obtido pelos processos de separação com membranas, considerando o atendimento das exigências técnicas, legais e sanitárias para diferentes usos industriais. Os resultados mostraram que os processos de separação por membranas apresentaram, de uma maneira geral, uma sensível melhora na qualidade do efluente final quando comparados com o atual sistema de pós-tratamento empregado pela indústria (flotador físico-químico), que promove eficiências de remoção nas faixas oscilantes de 3% a 29%, 44% a 70%, 40% a 46% e 50% a 58,5%, aproximadamente, para os parâmetros sólidos totais voláteis, turbidez, nitrogênio amoniacal e DQO, respectivamente. A microfiltração apresentou as seguintes faixas de eficiência de remoção, aproximadas: sólidos totais voláteis (51% - 64%), turbidez (83% - 99%), nitrogênio amoniacal (21% - 24%) e DQO (64% - 72%). A ultrafiltração apresentou as seguintes faixas de eficiência de remoção, aproximadas: sólidos totais voláteis (23% - 51%), turbidez (87% - 99%), nitrogênio amoniacal (54% - 69%) e DQO (77% - 85%). A realização do ensaio de microfiltração seguido de ultrafiltração nas melhores condições experimentais investigadas obteve resultados satisfatórios na remoção de aproximadamente 97% para a turbidez, 17% para os sólidos totais voláteis, 67% para a DQO, 38% para o nitrogênio amoniacal, 96% a 99,95% para os coliformes termotolerantes e 93 a 99,69% para os coliformes termorresistentes. Com o aumento da pressão para a microfiltração e ultrafiltração foi obtido maior fluxo permeado e melhor qualidade do efluente final. Embora os efluentes tenham proporcionado distintos valores de fluxo permeado, foram obtidas curvas de desempenho bastante semelhantes, caracterizando-se por uma queda do fluxo permeado nos primeiros minutos de filtração, seguido de um período onde ocorre declínio gradual, com uma tendência ao equilíbrio. De acordo com os requisitos físico-químicos e microbiológicos mínimos exigidos para o reúso de efluentes tratados, a microfiltração e a ultrafiltração atenderam alguns dos parâmetros monitorados, alcançando a qualidade exigida para o reúso em torres de resfriamento, lavagem de pisos, irrigação de áreas verdes, lavagem de veículos, proteção contra incêndio e descarga sanitária.
The food industry uses large volumes of water to meet the demand processes. Because of this, there is a large volume of generated waste that need to be addressed to ensure proper final destination. In view of the growing scarcity of water, the use rationalization of procedures of the water and the reuse of treated effluent arise as solutions to these problems. Application of separation processes by membranes in the treatment of wastewater for reuse food industry presents itself as an appropriate advanced treatment process. Thus, the aim of this study was to evaluate the use of membrane separation processes as advanced treatment of agroindustrial wastewater stemmed from a swine slaughterhouse, the western region of Paraná, aiming at the possibility of recycling these effluents. For this it was necessary: to define the physical-chemical characterization of the agro-industrial effluents; evaluate the use of microfiltration, ultrafiltration, microfiltration and ultrafiltration then under different conditions of pressure applied to the membrane, and evaluate the quality of the effluent obtained by separation processes with membranes, considering the care of the technical, legal and health requirements for different uses industrial. The results showed that membrane separation processes presented in a general way a considerable improvement in final effluent quality compared with the current tertiary treatment system used by the industry (physicochemical flotation) which promotes removal efficiencies in oscillating ranges from 3% to 29%, 44% to 70%, 40% to 46%, 50% to 58.5%, approximately, for the parameters: total volatile solids, turbidity, ammonia nitrogen and COD, respectively. Microfiltration had the following removal efficiency ranges, approximate: total volatile solids (51% - 64%), turbidity (83% - 99%), ammonia nitrogen (21% - 24%) and COD (64% - 72%). Ultrafiltration showed the following removal efficiency ranges, approximate: total volatile solids (23% - 51%), turbidity (87% - 99%), ammonia nitrogen (54% - 69%) and COD (77% - 85%). The completion of the test microfiltration followed by ultrafiltration under the best experimental conditions investigated achieved satisfactory results in the removal of approximately 97% for the turbidity, 17% total volatile solids, 67% for COD, 38% for ammonia nitrogen, 96% to 99.95% for thermotolerant and 93 to 99.69% for the heat-resistant coliforms coliforms. With increasing pressure to microfiltration and ultrafiltration permeate flux was increased and better quality of the final effluent. Although the effluents have provided separate permeate flow rates, very similar performance curves were obtained, characterized by a drop in permeate flux during the first minute filtration followed by a period where there is a gradual decline, with a tendency toward equilibrium. According to the physicochemical requirements and minimum microbiological required for the reuse of treated wastewater, microfiltration and ultrafiltration attended some of the monitored parameters, achieving the required quality for reuse in cooling towers, floor washing, irrigation of green areas , washing vehicles, fire protection and sanitary discharge.

The research also understood that at company X the three strategy propositions (value, profit, people) are achieved through the process of implementing the company‟s change initiatives for sustainability and in turn support the company to evolve towards a sustainable enterprise. The ability to make sustainability a fundamental aspect of its business decisions is what distinguishes company X such that it can successfully design, introduce and diffuse strategies, practices and cultural traits aligned with sustainable models The researcher further believes that change interventions or initiatives carried out at company X such as value delivery, workforce plan alignment and cash generation are expected to enhance responsibility and accountability of employees. At company X, individuals are informed and allowed a great deal of autonomy when it comes to generating ideas to tackle strategic initiatives. The sense of inclusiveness allows individuals in company X to change their identity and behaviour in line with ideal models of the sustainable enterprise.

Full textAbstract:
Natural soils in the Appalachian coal mining region occur on steep slopes and are often thin, rocky, acidic, and/or infertile. This often makes use of natural topsoil for surface coal mine reclamation impractical. Sandstone (SS) and siltstone (SiS) topsoil substitute materials in mixed and pure treatments were compared to ascertain their effects on soil genesis and tall fescue (Festuca arundinaceae Schrab.) growth in a rock mix study. A second surface amendment experiment with similar objectives was established and contained treatments of sawdust, topsoil, a control, and four rates of sewage sludge.
Soil pH, extractable P, and coarse fragment contents decreased at the soil surface from 1982 to 1984. The CEC decreased from 1982 to 1983 due to leaching of cations solubilized from carbonates, but stabilized by 1984. Soil total-N and water availability increased from 1982 to 1984.
Particle size distributions changed as sand and >2 mm sized materials weathered into silt and clay sized particles. As sand contents decreased over time, silt contents increased. Morphologically distinct A horizons developed in these soils rapidly and were formed primarily by plant rooting and organic matter additions. Treatment application, topsoil substitute placement, and grading also created morphologically distinct horizons.
Fescue biomass production indicates topsoil substitutes support more vigorous vegetative growth than topsoil, especially when topsoils are mixtures of subsoil and A horizons. Biomass production was primarily limited by N, P, and water availability. Blended rock mixes consistently supported higher biomass production than pure SS and SiS treatments. Municipal sewage sludge applied at rates-56 Mg/ha equaled or exceeded inorganic fertilization for establishment and maintenance of tall fescue stands, and did not cause heavy metal phytotoxicity.M.S.

Full textAbstract:
This study is aimed at developing policies for energy efficiency by observing the past changes of energy use in Indonesia???s manufacturing sector over the period 1980???2000, and to investigate mitigation options for energy-related CO2 emissions in the sector. The first part of the study uses decomposition analysis to assess the effect of the changes in energy consumption and the level of CO2 emissions, while the second part investigates energy efficiency improvement strategies and the use of economic instruments to mitigate CO2 emissions in the manufacturing sector. Economic activity was the dominant factor in increasing energy consumption over the whole period of analysis, followed by the energy intensity effect and then the structural effect. The increase in aggregate energy intensity over the period 1980-2000 was mainly driven by the energy intensity effect. In turn, the technical effect was the dominant contributor to changes in energy intensity effect, with the fuel-mix effect being of lesser importance. Changes in CO2 emissions were dominated by economic activity and structural change. Sub-sectors that would benefit from fuel switching and energy efficiency improvements are the textile, paper, and non-metal sub-sectors. Three main options for reducing CO2 emissions from the manufacturing sector were considered: the imposition of a carbon tax, energy efficiency initiatives, and other mitigation measures. A carbon tax was found to reduce sectoral emissions from the direct use of oil, gas and coal, but increased the demand for electricity. At the practical level, energy efficiency improvements can be implemented by adopting energy efficient technologies that can reduce aggregate energy intensity up to 37.1 per cent from the base-year level, estimated after imposition of a carbon tax at $30 per tonne of carbon. A major priority for energy efficiency improvements was found to be in the textile and the paper and chemical sub-sectors. A mitigation measure such as the Clean Development Mechanisms could be encouraged in order to reduce projected emission levels. The preferred option would be the adoption of energy efficient technologies in the textile, chemical, paper and non-metal sub-sectors.

Thesis (MTech (Public Relations Management))--Cape Peninsula University of Technology, 2016.The history of public relations include facets of “publicity” and “press agentry,” and has matured beyond these narrow, tactical functions, rising to accept positioning as strategic communications which can drive corporate social responsibility decision-making that resonate credibly with community stakeholder. The study explored public relations models of communication within stakeholder engagement to establish corporate social responsibility projects in the mining sector in Richards Bay, South Africa. The stakeholder engagement process depends greatly on principles outlined in the King Reports, which includes a stakeholder ‘inclusive approach’ and ethical guidelines for ‘governing stakeholder relationships’ and emphasises ‘sustainable development’. Furthermore, a socially responsibility business integrates the economic, legal, ethical and discretionary obligation of business to society and further recognizes its place in the broader community. Although qualitative research design was chosen for this study, the research used purposive sampling to select individuals and groups for data collection on the stakeholder communication experience. Six Individual in-depth interviews and one focus group interview were conducted with the organisation’s Communities and Corporate Relations team and the community leaders. The research reports that the corporate social responsibility stakeholder engagement process has five stages (consultation, engagement, agreement, decision making and feedback) and there is an evaluation process on community development projects set by the organisation. Consequently, the organisation and the communities both benefit from the corporate social responsibility projects. Additionally, the analysis shows that the model used for stakeholder engagement within corporate social responsibility is the mixed-motive model of public relations. Hence, the relationship between the organisation and its host communities is established and maintained, as well as the social licence to operate and reputation is enhanced. Therefore the research concludes that a public relations’ mixed-motive model of communication is best suited for stakeholder engagement in order to establish corporate social responsibility projects in the host communities that can enhance favourable organisation-community relationships. The model intends to achieve equilibrium between the organisation and the community stakeholder. However, further research is recommended into the development of a new African public relations model of communication that encompasses the concept of ‘Ubuntu’ where the community leader is the final decision maker in consultation with the traditional council.

Full textAbstract:
One of the greatest challenges facing the world today is integrating industrial activities such as mining with environmental integrity and social concerns. Monitoring is fundamental to environmental management, both to assess the adherence to standards and to allow environmental managers to learn from practical experiences. However, a problem arises when the regulatory authorities cannot keep up with their mandate of enforcement and compliance monitoring. This research examined how the Department of Minerals and Energy (DME) implements the concept of sustainable development in the mining sector of the Eastern Cape (EC) and, more specifically, the extent to which the Mine Environmental Management (MEM) section is able to effectively monitor compliance of mining operations with environmental legislation. This was the first systematic compilation of statistical data for the DME, and presents the first study in the EC regional office in terms of environmental sustainability. Results indicate that there has been a sustained increase in mining activity over the past three years, possibly as a result of the boom in the construction industry and the accelerated road maintenance and improvement programmes in the Eastern Cape. Mining applications received by the DME have increased by 47% from 2006 to 2007 (January-May) and by a further 100% from 2007 to 2008. In addition to the increasing number of mining concerns being established, 98 mining concerns will need to apply for the conversion of their old order rights to new order rights by the 1st May 2009. Mining in the province is predominantly small scale with mining permits (mined areas less than 1.5Ha) making up 52.3% of all applications, with larger mining concerns contributing 29.3% and prospecting contributing the remaining 18.4%. In terms of compliance inspections, the EC regional office is required to conduct 120 environmental compliance inspections annually in terms of contributing to sustainable development. The MEM section exceeded this target since 2003. However, when the number of operational mines is considered, 120 inspections per year equates to one mine being visited, on average once every four years (based on 2008 data). Based on projected figures (number of compliance audits and number of operational mines) for 2009, the DME’s target of 150 inspections for 2009/10 combined with the limited staff D. Watkins – MBA Dissertation 2008 capacity will, at best, mean that mines would be inspected once in seven years. However, the target of 150 inspections will not actually even cover the expected number of EMP evaluation inspections. This has serious implications in terms of regulating the compliance of the mining concerns with their EMPR’s. The low level of compliance monitoring can be directly related to staff capacity and logistics problems at the regional office as well as provincial targets being based on staff capacity rather than the number of operational mines. Thus, considering potential environmental damage associated with mining operations and the capacity constraints of the MEM to conduct frequent compliance audits, it is likely that mining operations will have negative implications for sustainable development in the region. Currently there are many challenges facing the DME in terms of contributing positively to sustainability in the mining sector and there is a need to base future actions on the idea of continuous improvement and ultimately progress.

With an economic slowdown globally, huge food shortages and record-high fuel prices, it has never been so important for countries to guard their natural resources to ensure future sustainability. The South African energy generation industry, of approximately 40 000 Mega Watt (MW), consists largely (90%) of coal-fired power stations, with the remainder comprising of nuclear and pumped storage schemes which are regarded as environmentally neutral. It is only recently that Eskom and independent power producers (e.g. Darling Independent Power Producer Wind farm with an estimated 10 MW) embarked on utilising South Africa's natural resources to generate electrical power. South Africa's access to inexpensive coal and paid off coal-fired power stations has made it difficult to justify the investment in renewable energy. However, on 31 March 2009 South Africa became the first African country to introduce a feed-in-tariff for renewable energy (Gipe, 2009). The hope is that this initiative would stimulate the investment in green energy generation. Eskom and municipalities are currently the only entities that have licences from the National Energy Regulator of South Africa (NERSA) to buy bulk electricity from power producers. The question therefore arises: if green electricity is more expensive to generate and is sold at a price premium to Eskom and municipalities, would they pass the premium on to consumers; can they differentiate the green electricity product and will consumers be willing to buy at a premium price? This research study aims to answer if businesses would be willing to pay a premium for green electricity, why they would be willing to buy it, which factors influence the purchasing decision and what barriers exist that will deter a purchase. A survey was conducted on businesses in the Western and Northern Cape of South Africa. The businesses sampled have a notified maximum demand of 50kVA or higher and excludes the re-distributor (City of Cape Town) customers. Approximately ten per cent of businesses would be willing buy green electricity. Most of these businesses have indicated that they are willing to pay a premium of five to nine per cent for green electricity. The businesses that are willing to pay the largest premiums (>10%) are in the electricity, gas, water, finance, insurance, real estate, business services, manufacturing, transport, storage and communications sector. Businesses that are willing to buy green electricity: • Have a strategy to reduce their carbon footprint; • Want to be community leaders (altruistic motivators); • Have as their biggest barrier the additional cost of green electricity; and • Feel that power utilities should be required to include a minimum percentage of green energy in their energy mix.

The present study investigated the relationship between level of security clearance in engineering occupations and stress. A total of 63 male employees in the field of engineering and design with varying levels of security clearance employed by a large Southwestern defense company participated in the study. Data was obtained utilizing the Engineering Stress Questionnaire which measures sources of stress, work locus of control, social support, job difficulty, job characteristics, perceived stress, and demographic variables. T-tests revealed no statistically significant differences between employees with low security clearances and high security clearances with regard to perceived stress level. However, correlational support was found for hypotheses involving social support, job difficulty, job characteristics, sources of stress, and perceived stress. Path analysis was performed to investigate the impact of variable relationships.

Adequate supply and availability of nitrogen (N) is a major factor hindering successful revegetation of reclaimed surface mines. Because topsoils are often unrecoverable, “topsoil substitutes”, made up of overburden materials devoid of N, are often used on reclaimed surfaces. Four replications of seven surface treatments were applied to 12 m² plots of 2:1 sandstone:siltstone material on a reclaimed coal surface mine in Wise Co., VA: 1) fertilizer (168 kg/ha N, 147 kg/ha P, and 139 kg/ha K), 2) limed (7.8 Mg/ha), fertilized topsoil (30 cm deep), 3) 112 Mg/ha sawdust + fertilizer + 336 kg/ha slow-release N, and 4-7) lime-treated municipal sewage sludge at rates of 22, 56, 112, and 224 Mg/ha. Nitrogen availability after 40 mo (as determined by aerobic and anaerobic incubations) in sawdust- and sludge-amended soils was two to 20 times higher than in fertilized and topsoil-amended soils. Moisture holding capacity was nearly twice as high in sawdust-amended soils as in all other treatments. Soil nitrate (NO₃⁻) levels (0-20 cm layer) in excess of 75 μg/g were detected in the 112 and 224 Mg/ha sludge plots 28 mo after application. Stem volumes of three-year-old pitch X loblolly pines (Pinus rigida X taeda) were four times larger in soils amended with sawdust + slow-release N and were twice as large in soils amended with 22 and 56 Mg/ha sludge compared to fertilized-only seedlings. Increased seedling mortality was observed in the 112 and 224 Mg/ha sludge treatments, possibly due to high soluble salt levels and/or manganese deficiencies. The availability of N from sawdust + slow-release N or sludge (≤ 56 Mg/ha) is better than that of inorganic fertilizer for sustained tree growth. These amendments are recommended for reclamation to the extent that they are economically available.M.S.

Thesis (MA)--Stellenbosch University, 2014.ENGLISH ABSTRACT: Since the rise of the modern corporation in the late 19th century, the debate on the relationship between business and society has flourished, and the negative impact of businesses became evident as the number and scale of large corporations increased. As a result of the globalization of trade and economic activity, regulating and auditing multinational companies have become both more important and more problematic. Along with the new challenges to be met by companies operating in foreign countries, these factors have resulted in a greater demand for corporate social responsibility (CSR). Originating as an Anglo-American management idea, CSR has spread and become a well-established tool for businesses worldwide. In today’s global capitalist system, characterized by open markets, it is widely acknowledged that it is the role of the state to establish the preconditions for the proper functioning of markets by defining legal rules, establishing enforcement bodies, and providing public goods. However, many corporations choose to go beyond the required regulatory levels and voluntarily engage in CSR. Studies of CSR have long been dominated by business and economic scholars, usually with the aim to confirming or denying CSR as a tool for profit-maximization, and until the last decade, social and political scientists have shown little interest in CSR. From a political science view, the relation between the state, markets and corporations is of interest, but few studies have investigated how political institutions influence corporate behavior. This study has therefore researched the institutional determinants of CSR by analyzing the efforts and the role of the Norwegian government in promoting CSR in the shipping industry. The White Paper on CSR was used as guide to the government’s approach to CSR, and was analyzed in light of the specific CSR challenges faced in the shipping industry. For this purpose, a qualitative methodology and case study research design was adopted to provide in-depth information. New institutional theory and comparative political economy provided the theoretical framework for the study, and helped in answering the main research question: What is the role of the Norwegian government, as a political institution, in promoting CSR in the Norwegian shipping industry? as well as the sub-questions. The study identified both strengths and weaknesses in the government’s role as CSR promoter, and argued that the predominantly international focus of the White Paper is suitable for globally oriented industries, like shipping, while reducing its relevance for nationally oriented firms. The study further found that the government as institution provides the industry with CSR incentives, other than financial ones, as it sets the standards for what is perceived as modern and just corporate behavior. In addition, CSR in the shipping industry was found to take an explicit form, and to reflect the national institutional environment. The findings stand in contrast to the way in which the above-mentioned theories expect CSR to take shape in coordinated market economies. In broader sense, the findings affect the perception of the relationship between CSR as a management tool and strategy, and CSR as a political and regulatory tool that may be used actively by authorities.
AFRIKAANSE OPSOMMING: Sedert die opkoms van die moderne korporasie in die laat 19de eeu, het die debat oor die verhouding tussen besigheid en samelewing floreer terwyl die negatiewe impak van besighede sigbaar geword het soos die aantal en omvang van groot korporasies toegeneem het. As gevolg van die globalisering van handel en ekonomiese aktiwiteit, het die regulerende en multinasionale ouditeringsmaatskappye beide belangrik en meer problematies geword. Tesame met die nuwe uitdagings wat maatskappye in vreemde lande moet ontmoet, het hierdie faktore aanleiding gegee tot ‘n groter vraag na korporatiewe sosiale verantwoordelikheid (KSV). KSV het sy oorsprong as ‘n Anglo-Amerikaanse bestuursidee gehad en het ‘n goed gevestigde hulpmiddel vir besighede wêreldwyd geword terwyl dit ook versprei het. In vandag se globale kapitalistiese sisteem wat deur oop markte gekenmerk word, word dit wydverspreid erken dat dit die rol van die staat is om voorwaardes vir die behoorlike funksionering van markte te vestig deur regsreëls te definieer, handhawingsliggame te vestig en publieke goedere te verskaf. Baie korporasies verkies egter om verder as die vereiste regulerende vlakke en vrywillige deelname in KSV te gaan. Studies van die KSV is vir lank oorheers deur besigheid- en ekonomiese geleerdes wat gewoonlik die doel gehad het om die KSV te bevestig of te ontken as ‘n hulpmiddel vir wins-maksimalisering, en tot en met die laaste dekade het sosiale en politieke wetenskaplikes min belangstelling in die KSV getoon. Uit die Politieke Wetenskaplike oogpunt is die verhouding tussen die staat, markte en korporasies van belang terwyl min studies al ondersoek het hoe politieke instellings korporatiewe gedrag beïnvloed. Hierdie studie het dus die bepalende faktore van die KSV nagevors deur die pogings en die rol van die Noorweegse regering in die bevordering van KSV in die skeepsvaart te analiseer. Die Witskrif op KSV is gebruik as ‘n gids vir die regering se benadering tot die KSV, en is ontleed in die lig van die spesifieke KSV uitdagings wat in die seevaart industrie in die gesig gestaar word. Vir hierdie doeleinde is ‘n kwalitatiewe metodologie en gevallestudie navorsingsontwerp aangeneem om in-diepte inligting te verskaf. Nuwe institusionele teorie en vergelykende politieke ekonomie het die teoretiese raamwerk vir die studie verskaf en het gehelp in die beantwoording van die hoof navorsingsvraag: Wat is die rol van die Noorweegse regering, as ‘n politieke instelling, in die bevordering van KSV in die Noorweegse seevaart industrie? Sowel as die sub-vrae. Hierdie studie het beide sterkpunte en swakpunte in die regering se role as KSV promotor identifiseer en het geargumenteer dat die oorwegende internasionale fokus van die Wit Skrif geskik is vir globaal georiënteerde industrieë soos seevaart, terwyl die toepaslikheid van nasionaal oriënteerde firmas verminder is. Die studie het verder bevind dat die regering as instelling KSV insentiewe aan die industrie anders as finansiële verskaf het, deur dat dit die standaarde stel vir wat gesien word as moderne en regverdige korporatiewe gedrag. Daar is verder bevind dat die KSV ‘n eksplesiete vorm aangeneem het in die seevaart industrie om die nasionale institusionele omgewing te vertoon. Die bevindings staan egter in teenstelling tot die manier waarop die bogenoemde teorieë van die KSV verwag om vorm aan te neem in gekoördineerde mark ekonomieë. In die breër sin beïnvloed die bevindings die siening van die verhouding tussen KSV as ‘n bestuur hulpmiddel en strategie en KSV as ‘n politieke en regulerende hulpmiddel wat aktief deur owerhede gebruik kan word.

Thesis (LLM) -- University of Limpopo, 2012The study focuses on rehabilitation, since absence of proper rehabilitation process result in indelible damage to the environment. South Africa, like many other countries, is faced with many environmental problems caused by mining. These problems are particularly caused by, inter alia, abandoned mining areas without rehabilitation, inadequate environmental impact assessment after closure, inadequate financial provision for rehabilitation, and lack of monitoring and aftercare system after post mine closure. The study found that many Companies ignore laws governing prospecting, extraction and rehabilitation. The main purpose of this research is to investigate and recommend guidelines in the rehabilitation process so as to instil respect for the environment. The study therefore recommended strict legislation relating to environmental protection against mining.

Full textAbstract:
Thesis (Master of Engineering in Chemical Engineering)--Cape Peninsula University of Technology, 2018.Acid rock drainage (ARD) is one of the most severe environmental challenges currently faced by the mining industry worldwide. ARD is formed from the oxidation of sulphide-bearing minerals, particularly pyrite, in the presence of water and oxygen. ARD generation is accelerated by the presence of naturally occurring iron and sulphur-oxidizing micro-organisms, which regenerate leaching agents that facilitate sulphide mineral oxidation. ARD pollution is characterized by a high concentration of metals and sulphates in solution, low pH and a high salt content (salinity) in the environment, contaminating soil and groundwater. In South Africa, ARD is a major challenge in the gold and coal mining industries, where millions of tons of sulphide waste rock and overburden are generated and discarded. Characterization of these waste materials is required to develop an appropriate disposal strategy to minimise the risk of pollution and the generation of ARD. Potential ARD generation prediction from waste rock depends on the precise characterization of ARD potential using Biokinetic tests. Commonly used ARD prediction methods are static and long-term kinetic tests. Static tests provide data for a worst-case scenario focussing on strong acid chemical leaching potential to give an overall acid forming potential of a sample. Such kinetic tests provide data illustrating the rate of the net acid generation capacity of mine waste. However, these tests are capital intensive and time-consuming and fail to provide adequate information on the effect of micro-organisms on the overall net acid generation capacity of mine waste. The Biokinetic test reported herein and developed at the University of Cape Town, focusses on addressing a worst case scenario provided by static tests in a cost-effective manner and reduced time frames provided for by conventional kinetic tests. This test primarily provides relative rates of ARD generation in the presence of micro-organisms within 90 days. However, the Biokinetic test is at the developmental stage and thus far, has not been consistently used for different waste ores to determine a standardised approach. Therefore, the aim of this study was to investigate the effects of microbial consortia and to develop a standardisation approach for the test for ARD formation potential using gold-bearing and copper-bearing waste rock. Additionally, to refine the Semi-continuous Biokinetic test simulation, a flow-through system where there is minimal seepage in the waste deposit, was also developed. The sulphur content of the gold and copper-bearing samples used in this study was between 2.3 and 3.15%, respectively. These waste rock samples were found to be potentially acid- forming. In the Biokinetic test, finely milled waste rock samples were slurrified, inoculated with consortia and cultured under standard bioleaching conditions. Leaching and acidification rates were monitored.

Full textAbstract:
Although remotely sensed data have been employed to assess various environmental problems, relatively few previous studies have focused on the impacts of mining. In Indonesia, mining activities have increasingly become one of major drivers of land cover change. The majority of remote sensing research projects on mining environments have exploited optical data which are frequently complicated by tmospheric disturbance, especially in tropical territories. Active remote sensors such as Synthetic Aperture Radar (SAR) are invaluable in this case. Monitoring by Independent SAR data has been limited due to single polarisation. Dual-polarised data have been employed considerably, although for some forestry applications the data were found insufficient to retrieve basic information. This Masters thesis is devoted to assess fully polarimetric SAR data for environmental monitoring of the tailings deposition zone of the PT Freeport Indonesia Grasberg mine in Papua, Indonesia. The main data were two granules of the AIRSAR datasets acquired during the PACRIM-II campaign. To support the interpretation and analysis, a scene of Landsat ETM February 2001) was used, juxtaposed with classified aerial photographs and a series of SPOT VEGETATION images. Both backscattering information and complex coherence matrices, as common representations of polarimetric data, were studied. Primary applications of this research were on degraded forest and environmental rehabilitation. Most parts of Indonesian forests have experienced abrupt changes as an impact of clear-cut deforestation. Gradual changes such as those due to fire or flooded tailings, however, are least studied. It was shown that the Cloude-Pottier polarimetric decomposition provided a convenient way to interpret various stages of forest disturbance. The result suggested that the Entropy parameter of the Cloude-Pottier decomposition could be used as a disturbance indicator. Using the fully polarimetric dataset combined with Support Vector Machine learning, the outcomes were generally acceptable. It was possible to improve classification accuracy by incorporating decomposition parameters, although it seemed insignificant. Land rehabilitation on tailings deposits has been a central concern of the government and the mining operator. Indigenous plant pioneers such as reeds (Phragmites) can naturally grow on dry tailings where soil structure is fairly well developed. To assist such efforts, a part of this research involved identification of dry tailings. On the first assessment, interpretation of surface scatterers was aided by polarimetric signatures. Apparently, longer wavelengths such as L- and P-band were overpenetrated; hence, growing reeds on dry tailings were less detectable. In this case, the use of C-band data was found fairly robust. Employing Mahalanobis statistics, the combination of HH and VV performed well on classification, having similar accuracy with quad polarimetric data. Extension on previous results was made through the Freeman-Durden decomposition. Interpretation using a three-component image of odd, even bounce and volume scattering showed that dry and wet tailings could be well distinguished. The application was benefited from unique responses of dielectric materials in the tailings deposit on SAR signals; hence it is possible to discriminate tailings with different moisture levels. However, further assessment of tailings moisture was not possible due to security reasons and access limitations at the study site. Fully polarimetric data were also employed to support rehabilitation of stressed mangrove forest on the southern coast. In this case, the Cloude-Pottier decomposition was employed along with textural parameters. Inclusion of textural properties was found invaluable for the classification using various statistical trees, and more important than decomposition parameters. It was concluded that incorporating polarimetric decompositions and textural parameters into coherence matrix leads to profound accuracy.

Bibliography: pages 134-147.Pollution control regulations directed at the land-based factories of the Southern African fish processing industry do not appear to promote the required level of investment in pollution control systems. Two self-administered mail-questionnaires comprising undisguised fixed-alternative and open-ended questions were constructed to survey the opinions and viewpoints of a census consisting of twenty-seven senior managers responsible for making pollution control investments in the demersal and pelagic sectors of the fish processing industry. The first questionnaire was directed at establishing the relative importance of factors that influence waste and pollution control investment decisions as well as the perceptions and preferences of managers with regard to various pollution control policy options. Descriptive statistics such as the modal class were used to summarize the distribution of opinions and viewpoints within the research population. Rank ordered preference data was analyzed using a multidimensional unfolding computer algorithm. This structural multivariate statistical method is a special case of non-metric multidimensional scaling that generates perceptual maps which can aid in the discovery of the hidden structure underlying multidimensional decisions. Investments in waste and pollution control do not appear to have a high priority when compared to other strategic investments that the fish processing industry managers may make. The relative importance of factors that could influence the managers of the industry to invest in waste control equipment appear to be determined by the perceived financial returns that can be expected from such investments. Findings suggest that pollution control legislation is rendered ineffective due to inadequate enforcement. However, it appears that existing legislation needs to be rationalized in order to facilitate compliance. The most favoured pollution control instruments were those that lowered the cost of legally mandated expenses such as subsidies and income tax allowances. These were followed by permit systems which specified the allowable characteristics of discharges while allowing individual companies freedom of choice as to the method of achieving compliance. The second questionnaire was used to verify the researcher's interpretation of the findings and preliminary conclusions drawn from the replies to the first questionnaire.
