The purpose of this study was to understand the lived experiences of skydiving instructors who have shaped the instructional practices of experienced and active accelerated freefall instructors (AFFIs) in Central and Southern Florida. By contributing to the training curriculum, this research attempted to close the experiential gap between novice and senior instructors in a more efficient manner. Due to the complex nature of teaching skydiving and an absence of an opportunity for a skydiving instructor in training to work in freefall with non-certified skydivers, understanding the lived experiences of active AFFIs is of critical importance. This study aimed to answer the following research questions: (a) How do active accelerated freefall training instructors personalize the lessons learned in the AFFI instructor training course, forming their own best practices and instructional style? and (b) What roles do lived skydiving experiences, both significant and critical, play in the development of an active AFFI’s current instructional style and best practices? Sites selected included five dropzones located in Central and Southern Florida, with three of those sites yielding a total of 10 participants. Data were collected regarding basic demographic information as well as about the lived experiences of the active AFFIs through both structured and semi-structured interviews and document analysis. Interviews were conducted either in-person or over the phone based on the preference of the participants. Data analysis took place in three phases: separation of qualitative and quantitative data, open coding, and axial coding following Merriam’s (2009) process of coding. Findings revealed an understanding that accelerated freefall (AFF) instruction has become rooted within the culture and experiences of the skydiving community through the stance “license to learn.” This stance has led to the emergence of an educational model outlining the roles culture and experience play not only in the development of the active AFFIs, but also how those lessons are passed on to the next generation of AFFIs. Findings in this research will play a significant role in the development of future curricular adjustments, highlighting the importance of this stance while also providing a solid foundation for future inquiry. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2019. / FAU Electronic Theses and Dissertations Collection

D.Phil. (Engineering Management) / The construction industry has been recognised internationally as one of the most dangerous industries in which to work, with the statistics often explained in terms of the industry’s inherently hazardous nature. In Botswana a total of 281 fatalities were reported to government agencies, mainly recorded in the high-risk sectors over the period of 2000-2004. The purpose of this study was to investigate the role played by key stakeholders in the health and safety (H&S) performance of the Botswana construction industry and to evaluate their level of H&S commitment and implementation. The aim was to determine how clients, designers and contractors can successfully contribute to H&S performance. Five objectives were identified in this research study. The first was to examine the role of key stakeholders in minimising H&S accidents and incidents in the overall H&S performance of the construction industry of Botswana. The second was to establish whether relevant health and safety planning measures contribute to health and safety performance of the construction industry in Botswana. Thirdly, it was to investigate the extent to which the existing legislative framework is relevant to health and safety performance in the construction industry. The fourth was to determine health and safety commitment levels of clients, designers and contractors’ top management in the construction industry of Botswana. The final objective was to design a multi-stakeholder consultative framework that would address H&S from inception to implementation of the construction project. These objectives were achieved through a research design which included a literature review, methods used and procedures developed to administer the questionnaires, data-collection and analysis through various statistical methods. These included descriptive statistics and nonparametric inferential statistics. The results are then presented in statistical format, tables and graphs. While the literature review revealed that construction industry H&S in developed nations is driven by legislation and regulations, the analysis indicated that there is neither statutory obligation nor the desire on the part of designers and the clients to consider H&S...

While asbestos has been called a 'miracle substance' because of its unique properties, asbestos has also caused cancer in those exposed to its indestructible fibres. This mix of benefits and costs has made the regulation of asbestos particularly difficult for policymakers; in both countries, regulation has been characterized by exceptional measures. In Canada, regulating asbestos has led to innumerable government studies, including the Ontario Royal Commission on Matters of Health and Safety Arising from the Use of Asbestos (1984). The Commission's Report was unique in its extensive scope and detail. Its three volume report included a detailed treatment of asbestos-related diseases, quantitative risk estimates, and assessments of current regulations. The regulatory history of asbestos in the US was also somewhat exceptional. It involved a protracted battle between the Environmental Protection Agency and the Office of Management and Budget. Out of this battle came a House Subcommittee investigation into OMB interference in EPA rulemaking (1985). The comprehensiveness of the Royal Commission's Report is highly significant given that detailed scientific explanations of policy, and the criteria used to balance costs and benefits are usually not explicitly revealed by Canadian regulators. In this sense, the somewhat anomalous nature of the Commission's Report offers an especially detailed view of regulating hazardous substances in Canada. Like the Royal Commission Report, the House investigation provides an extraordinarily detailed look at the politics of regulating a hazardous substance. Out of these involved deliberations, though, emerge very different policies on asbestos. While the US has implemented a three-stage ban, Canadian regulators view asbestos primarily as an occupational problem. The workplace standards of the US, Ontario and Quebec differ, with the US being more stringent. The contributions of this paper stem from its balanced consideration of scientific and political determinants and its comparative nature. This balanced consideration illustrates the double impact of science. While science can set the boundaries of a policy debate, uncertain areas of scientific evidence are usually politicized by competing interests. Thus, the less science is certain, the more politics matters. Within the boundaries set by science, various political forces have an impact on the policy process. Policies are shown to emerge from very different interrelationships between state structures and societal actors, influenced by varying degrees of economic dependence on asbestos. Group theory alone fails to explain the divergent policy outcomes; so do neo-Marxist and institutionalist approaches. Thus, this study demonstrates the superiority of integrative approaches, as opposed to those which emphasize one causal variable at the expense of others. / Arts, Faculty of / Political Science, Department of / Graduate

Industries related to agricultural cooperatives record some of the highest injury rates in the U.S. Therefore, agricultural cooperatives are highly motivated to invest in occupational health and safety (OHS). This thesis examines the economic efficiency of OHS investments at agricultural cooperatives and identifies cooperative characteristics leading to greater economic efficiency of OHS investments. A multiple input-output data envelopment analysis (DEA) is used to estimate technical efficiency. The effects of cooperative characteristics on the efficiency of OHS investments are estimated using ordinary least squares, censored regression, truncated regression, and the Simar and Wilson (2007) bootstrap procedure. Results show that the mean technical efficiency score was 0.833. Furthermore, a cooperative’s annual insurance premia has a significant, negative relationship with technical efficiency. In contrast, the experience levels of a cooperative’s top safety person and top managerial person and a location’s total workers employed have significant, positive relationships with efficiency in all estimated models. / North Dakota State University.

The transportation of anhydrous ammonia, which is classified as a hazardous material, poses risk to the transporter, surrounding communities, and the environment. The commercial transportation of anhydrous ammonia is highly regulated, while the private transport is not subject to the same degree of mandates. Given the regulatory policies, the current locations of licensed dealers of anhydrous ammonia within North Dakota may be leading to a scenario where a private transporter has an incentive to disobey these policies and thereby expose him/herself, the surrounding communities, and the environment to unnecessary risk. Three stylized counties were constructed to represent the attributes of the eastern, central, and western counties of North Dakota. Attributes included transportation infrastructure, population distribution, and crop composition. Mathematical programming techniques were then utilized to determine the number and optimal location of licensed dealers of anhydrous ammonia within these counties. The results were then compared and contrasted with the current locations of licensed dealers throughout North Dakota to determine if the regulatory policies are sufficient in that they are not encouraging unsafe actions of the transporters and thereby endangering the transporters, surrounding communities, and the environment. The results indicated that the current regulatory structure associated with the transportation of anhydrous ammonia is sufficient to limit incidents.

In recent years, concern about food safety linked to health issues has seen a rise in private food safety standards in addition to the regulations set by the Food and Agriculture Organisation (FAO) in collaboration with the World Health Organisation (WHO). These have presented challenges to producers and exporters of agricultural food products especially the producers of fresh fruits and vegetables. In spite of the food safety-linked challenges from the demand side, the vast range of business-environment forces pose equally formidable challenges that negatively impact on the exporting industries’ ability to maintain or improve their market shares and their ability to compete in world markets. The objective of this study was therefore to establish the competitiveness of the South African citrus industry in the international markets within this prevailing scenario. Due to the diversity of the definitions of competitiveness as a concept, this study formulated the following working definition: “the ability to create, deliver and maintain value and constant market share through strategic management of the industrial environment or competitiveness drivers”. This was based on the understanding that the international market shares of an industry are a function of forces in the business environment which range from intra-industry, external and national as well as the international elements. The unit of analysis were the citrus producers engaged in export of their products and the study made use of 151 responses by producers. The study adopted a five-step approach to the analysis of the performance of the South African citrus industry in the global markets, starting with the analysis of the Constant Market Share (CMS) of the South African citrus industry in various world markets, establishing the impact of the business environmental factors upon competitiveness, establishing the costs of compliance with private food safety standards, determining the non-price benefits of compliance with the standards, as well as highlighting the strategies for enhancing long-term competitiveness of the industry in the international markets. South Africa is one of the top three countries dominating the citrus fruit export market. Since its entry into the citrus fruit exports market in the 1900s, the industry has sustained its activity in the international market. The Constant Market Share Analysis shows that, amidst the challenges on the international market side, and the changes in the business environment, over much of which the industry has limited control and influence, the industry has maintained its competitive advantage in several markets. The CMS shows that South Africa’s lemons are competitive in America. Despite a negative trend, the South African grapefruit has been competitive in France, Greece, Italy, the Netherlands and Spain. Oranges have been competitive in the Greece, Italy, Portugal, UK, Asian and Northern Europe markets. Competitiveness in these markets has been due to the inherent competitiveness of the industry. Competitiveness in such markets as the Middle East has been attributed to the relatively rapid growth of these markets. The South African citrus industry has similarly undergone many major processes of transformation. The business environmental factors influencing its performance have ranged reform to the challenges beyond the country’s borders. These factors directly and indirectly affect the performance of the industry in the export market. They have influenced the flow of fruits into different international destinations. Of major concern are the food safety and private standards. Challenges in traditional markets as well as opportunities presented by demand from newly emerging citrus consuming nations have seen a diversification in the marketing of the South African citrus. The intensity of competition in the global market is reflected by the fluctuations in the market shares in different markets as well as the increase and fluctuations of fruit rejection rates in some lucrative markets such as America. A combination of challenging national environmental forces and stringent demand conditions negatively impact on revenues especially from markets characterised by price competitiveness. This study identified cost of production, foreign market support systems, adaptability, worker skills, challenges of management in an international environment and government policies such as labour and trade policies as some of the most influential obstacles to competitiveness. Some of the most competiveness-enhancing factors were market availability, market size, market information, market growth and the availability of research institutions. However, compliance with private standards still poses a challenge to the exporters. The different performance levels of the industry in various markets prove the dissimilarity of the demand conditions in the global market. These are supported by the negative influence associated with the foreign market support regimes as well as the challenges associated with compliance with private food safety standards. While market availability, market growth, market information and size were identified as enhancing competitiveness, the fluctuations and inconsistencies in the competitiveness of the industry in different foreign markets require more than finding markets. Resource allocation by both the government and the industry may need to take into account the off-setting of the national challenges and support of farmers faced with distorted and unfair international playing fields. Otherwise, market availability is not a challenge for the industry save meeting the specifications therewith as well as price competitiveness which is unattainable for the South African citrus producers faced with high production costs. For the purposes of further study, it is recommended that account should be taken of all the products marketed by the industry (including processed products such as fruit juices) in order to have a whole picture of the competitiveness of the industry in the international market. This study also proffers a new theoretical framework for the analysis of the business environment for the citrus industry and other agro-businesses. This framework takes into account the indispensability of the food safety standards and measures as well as the diversity of the global consumer and the non-negotiability of food trade for the sustenance of the growing population.

Risks are present in every aspect of business. As one of the biggest industries worldwide, the construction industry is plagued with risks. Being such a large industry, there are hundreds of contracts signed every day. These contracts range from new construction, refurbishment to maintenance. Some projects are simple and worth few thousands of dollars where others are complex and may cost hundreds of millions. Irrespective of how simple or complex the project is, all projects are exposed to risk and can go wrong (Edwards and Bowen, 2005). Construction is governed by complicated contracts and involves complex relationships in several tiers (Abdou, 1996). According to Sawczuk (1996) as soon as the employer and the contractor have signed a contract they have taken on board risks. Their awareness of the risk and the steps to be taken to manage their share of the risk, will determine the likelihood of problems occurring. Construction projects have an abundance of risk, contractors cope with it and owners pay for it. The construction industry is subject to more risk than any other industries. Taking a project from initial investment appraisal to completion and into use is a complex and time-consuming design and construction process. It requires a multitude of people with different skills and a great deal of effort to co-ordinate a wide ranges of disparate, yet interrelated, activities. Inevitably, this complex process is compounded by many unexpected events that may cause loss to the client and other involved parties (Shen, 1999; Flanagan and Norman, 1993). According to Carter et al. (1997) the construction industry is facing a more challenging environment than any time in the past. Client expectations have grown higher and they call for better quality and service. Smith (1998) highlighted that for years the South African building industry had a very poor reputation in managing construction risks. These risks could be prevented or reduced if management takes action at early stages ofthe project life cycle. In order to overcome these limitations and improve the image of the South African construction industry, this research aims to develop an innovative framework to enable construction contractors to identify, quantify and classify the risks associated with the Joint Building Contracts Committee (JBCC) Principal Building Agreement (PBA). This will help making decisions on informed bases. In addition, it will enable contractors develop particular course of actions to mitigate the effects ofthese risks. The research methodology designed to achieve this aim consisted of literature review, questionnaire and interview.

The European Union (EU), in 1992, issued the Temporary or Mobile Construction Sites (TMCS) Directive, which requires EU members to introduce specific law to improve health and safety (H&S) performance outcomes by placing specific duties on key stakeholders. This Directive led to the introduction of the first Construction (Design and Management) (CDM) Regulations in the UK construction industry on 31 March 1995 and since their introduction, the overall performance of construction H&S has improved gradually. However, despite this positive outlook, there are still significant concerns surrounding the implementation of the CDM Regulations, a subject on which empirical research has been very scanty. It is against such a background that this study investigates the practical implementation of the CDM Regulations and extends current knowledge and understanding, and develops a framework for appropriate remedial action by industry. The research method involved a thorough critical review of literature, semi-structured interviews, and two postal questionnaire surveys, using as research informants, practitioners with experience of the Designer, CDM Coordinator (CDM-C), and Principal Contractor (PC) roles under the CDM Regulations. Primary data were collected and analysed from in-depth interviews with six organisations purposively selected based on their construction design expertise and 122 questionnaires returned in total. The finding regarding lack of collaborative working amongst duty holders is a significant outcome of this study; a requirement expressed explicitly within the CDM Regulations, yet questionable in terms of its implementation. Further, the study reveals a number of statistically significant correlations between the extent of discharge of duties and their perceived degree of importance. However, the strength of the majority of these correlations is weak. In particular, the evidence indicates that 50% of the duties of the CDM-C are misaligned in terms of extent of discharge and perceived degree of importance, whereas 25% of the PC duties are also misaligned. This signals a lack of understanding regarding the importance of duties, towards achieving improved H&S management. Surprisingly, a comparison between extent of discharge of duties and their perceived degree of difficulty reveals that all the duties of the PC are statistically significant, meaning that the perceived degree of difficulty does not impede their extent of discharge. While 90% of the CDM-C duties are also statistically significant, again the same interpretation applies. Further, a consensus reached by Designers supports the view that CDM-Cs provide insufficient input throughout the planning and construction phase, raising doubt as to whether the duty holder is fit for purpose. Overall, the results confirm that interdependent working of duty holders is still a challenge, demonstrated by the Designer duty to ensure appointment of the CDM-C (Regulation 18(1)), the CDM-C duty to ensure Designers comply with their duties (Regulation 20(2)(c)), and the PC duty to liaise with the CDM-C and Designer (Regulation 22(1)(b)). Three recurring themes emerge from the results, that is: (i) collaboration, (ii) accountability and compliance, and (iii) facilitation, which in turn inform the remedial action framework comprising 13 remedial actions and 8 change drivers. Validation of the remedial action framework by 15 study participants reveals that, at least 10 remedial actions and 7 change drivers are considered likely to improve CDM implementation. The top three remedial actions are: (i) ensuring adequate arrangements for coordination of H&S measures; (ii) including provisions within the regulations specifying the stages for the appointment of duty holders; and (iii) amending the ACoP to provide guidance on determining what resources are adequate for a particular project. Whereas, the top three change drivers are: (i) management leadership; (ii) the proactive participation of duty holders; and (iii) training to equip duty holders with sufficient knowledge on provision of timely and adequate preconstruction information. Based on these outcomes, conclusions, recommendations, and further areas of research are drawn.
