Abstract:

Anaerobic digestion technology has not gained widespread acceptance on UK farms due mainly to the long return on investment periods involved. It has been suggested that co-digestion of agricultural and industrial wastes may enhance the economic viability of such installations. Batch and continuous digestion of cattle slurry and organic industrial wastes was carried out in specially constructed pilot plant digesters, to determine optimum mixtures of waste and digester loading rates. A total of 10 different wastes were tested, on a batch digestion basis, for their potential to co-digest with cattle slurry. Of these, 3 were chosen for continuous pilot plant trials, due to either a need to provide a disposal route for the waste, or positive effects of the waste on methane productivity. Chicken manure was found to slightly enhance methane productivity, but ammonia inhibition of methanogenic bacteria was noted over time. The organic fraction of municipal household waste (OFMSW) significantly enhanced digester methane productivity, while fish offal (FO) slightly enhanced methane productivity when added to the digester in small quantities, but quickly caused digester failure when added in larger amounts. An economic model of a digestion facility was developed and used to show the financial benefits of co-digestion.

Abstract:

New agricultural constructions in Czech Republic happen, in better case, privilege of civil engineer, in the worse case only privilege of the investor, in the past. While architects or enlightenment project architects with inventive and feeling for architecture, rarely interfered to their projection. In the practice, the preferred and implemented misconception, that it is a purely purpose-built buildings with economical advantageous solution type, when external design of the building and his effect in landscape plays just a minor role, meant a huge mistake, which disfeature face of a lot of villages. With the gradual development of organic and sustainable agriculture is obvious, that to the design of these buildings gets back the idea of invention and emotion of construction into the landscape. Essence of a dissertation is how to proceed with the draft of a new or completion of original organic farm in conditions of the Czech Republic and on which specific points to focus in the design. Objective of thesis is generalization of rules design new modern organic farm or new buildings on the existing organic farm, using the principles of organic architecture and architecture undemanding of energy, renewable source of energy and non-waste management and verification on the specific examples in the Czech Republic and neighboring Europa countries. Where else should apply the principles of organic architecture more than in the construction of organic farms. Moreover, organic farm offers a great number of functions and with related different operations with requirements for specific areas. This is an added bonus, diversity of construction and the possibility of building creativity in architectural solutions. It is then mainly limited functionality of the building, legislative, public health, fire and traffic regulations, with which any proposal must cope. Organic farms are a phenomenon, but also the future of sustainable agriculture in the Czech Republic, as well. Not only production side of organic farms, but also neglected building stock deserves the attention of experts. Only organic farm with the right comprehensive created building and energy concept on an ecological principle is becoming a well-functioning self-contained unit connected with the cycle of nature, the surrounding landscape and regional tradition.

Stroh, Oliver. "A hearing protection intervention system for agricultural workers." Thesis, University of Iowa, 2019. https://ir.uiowa.edu/etd/6863.

Abstract:

Twenty-two million US citizens are exposed to hazardous noise at work each year, putting them at risk for noise induced hearing loss. Noise induced hearing loss is preventable, cumulative, and irreversible with net economic impact estimated at $123 billion. While agencies such as the Occupational Safety and Health Administration have regulations in place to reduce noise induced hearing loss, these regulations are rarely enforced for agricultural workers. These workers have a low rate of hearing protection usage, with several studies finding that almost half of farmers never use hearing protection devices. Additionally, farmers have twice the hearing loss in higher frequencies and three times in mid-range frequencies than non-farmers. Use of hearing protection can reduce noise induced hearing loss, and agricultural workers are interested in increasing their usage. This makes them a promising group to target with a hearing protection intervention. This paper describes a system that combines a smartphone with a USB based noise dosimeter that can read within +/- 2 A-weighted decibels of a Class 2 sound level meter providing daily noise exposure monitoring. This device is worn by the agricultural worker throughout a work day, collecting location, accelerometer, and audio data. The data is then transferred onto the server and presented to the agricultural worker using a locally hosted website, giving personalized data of loud noise exposures that can be understood without the need for a safety specialist. The dosimeter’s data allows the agricultural worker to explore what sound pressure levels they are exposed to and get an estimate of their total noise exposure. The GPS, paired with audio clips of loud noises, allows the agricultural worker to determine what activities put them at risk of noise induced hearing loss, which are good indications of where to place hearing protection devices. The system was tested on a farm, comparing its output with several reference instruments. A-weighted, 1-second averaged sound pressure levels, GPS, and accelerometer data were collected while performing a variety of tasks indoors and outdoors. The smartphone’s external noise dosimeter read within +/- 2 dBA of the Class 2 reference dosimeter 59% of the time. The GPS devices had an average error of sub-4 meters between and the accelerometers had a mean absolute error of less than 0.1 g.

Abstract:

One of the most significant trends in data warehousing today is the integration of Metadata into data warehousing tools. A data warehouse is an area which exists on computer systems that is used for holding all of the data that an organization might possess. Metadata is ²data about data,² a dictionary and summary of data, that is held in a system catalog that is contained in a data warehouse. The purpose of this dissertation is four-fold: to show that by examining a database?s system catalog, information can be extracted from it that can be used to develop a structure for building operations research applications. To show that a database?s system catalog can be modified to hold the structure and the definition of a linear programming model. To show that a data table containing the linear programming model constraints can be automatically constructed based on the contents of the modified system catalog. And finally, to show that the modified system catalog can be used to guide a user in developing objective functions based on a given set of model constraints. Thus, the main contribution of the work is that it furthers the hybrid area of information technology/mathematical programming by exploiting metadata, as opposed to raw data, that is held in a data warehouse.

Abstract:

The water that is available for beneficial use in Utah is quickly approaching full appropriation; water that has been claimed is nearing the amount that is available for use. The Division of Water Resources of the State of Utah has organized a three-part plan to "Plan, Conserve, Develop and Protect Utah's Water Resources." One of these three elements has a focus to "provide comprehensive water planning." Such planning is best achieved when current and accurate data on the uses of the state's water are available. The primary purpose of this thesis was to provide an evaluation, from data collected on various case studies across the state, on the accuracy of water rights information. The studies were selected based on land that had recently been developed from agricultural usage to residential, commercial, or other municipal uses. After identifying the accuracy of the water rights information, observations to the methods of recording water right transfers were made. A template to summarize a municipality's water rights will also be made available.

Cette thèse porte sur le développement d'une approche de modélisation destinée à quantifier la durabilité de systèmes industriels à partir de biomasse (considérés comme des systèmes complexes), et à fournir un outil d’aide à la décision qui permette, en modifiant certaines de leurs caractéristiques, de diminuer leurs impacts environnementaux.Elle s’appuie sur deux études de cas régionales : la première permet de tester l’hypothèse théorique pour évaluer les facteurs qui contribuent à l’adoption par les agriculteurs du « panic érigé » (switchgrass) dans l’Etat du Michigan (USA), et les effets associés en termes d’impacts environnementaux, en utilisant un modèle multi-agents couplé à l’analyse du cycle de vie ; la seconde combine modélisation multi-agents et système d'information géographique par le biais d’une analyse de flux de matières et d’énergie pour révéler les opportunités symbiotiques d’un écosystème agro-industriel en Champagne-Ardenne (France).On montre que ces deux modèles fonctionnels ont une valeur ajoutée significative pour l’analyse de systèmes sociotechniques durables et la simulation de scénarios futurs
This research is about developing a modeling framework in order to quantify the sustainability of industrial systems for biomass energy (conceived of as complex systems), and to provide decisionmakers with an aiding-tool for reducing their environmental impacts by modifying some of their features.It draws upon two regional case-studies. In the first one, an hybrid agent-based/life cycle assessment approach is used to test the theoretical background, understand the main decision-making factors influencing farmers’ adoption of switchgrass ethanol in Michigan (USA) and assess how such patterns affect environmental impacts. In the second case-study, agent-based modeling and geographical information system are used together via material and energy flow analysis to reveal the potential for industrial symbiosis in the bio-economy cluster of Champagne-Ardenne (France). We show that both models have a significant added value for the analysis of sustainable complex systems and the simulation of future scenarios

Abstract:

Grafted vegetable seedlings have been proven to possess higher seed/non-seed diseases resistance and yields compared with non-grafted ones. Owing to the seasonality of vegetable planting and labor intensiveness of grafted seedling production (e.g., grafting operation), U.S. vegetable seedling supply chains suffer from high grafted seedling cost. To make grafted seedlings affordable for vegetable growers, low-cost production systems and cost-efficient grafting capacity must be achieved via optimal design of a grafting operation system and supply chain collaboration, respectively. Toward this end, a two-level simulation-based framework is proposed in this work for improving the overall performance of the grafted seedling supply chain by supporting both the grafted seedling production system design and supply chain collaboration decisions. The considered supply chain consists of a single grafted seedling producer that produces grafted seedlings and multiple vegetable growers that seasonally purchase grafted seedlings and produce vegetables to meet price-sensitive demand from the downstream market. More specifically, the low level of the proposed framework focuses on the grafted seedling production system design by integrating discrete event simulation (DES) together with a fuzzy analytic hierarchy process (AHP) for multiple criteria (i.e. production cost, capital investment, production throughput time, resource utilization, and product quality). A Unified Modeling Language (UML)-based simulation modeling and generation approach is developed to automatically generate simulation models of various production system design alternatives. UML information models are developed to provide the system structural information for simulation model generation, production information for simulation execution, and output requirement information for defining simulation outputs. The performance of the production system design alternatives for the aforementioned criteria is evaluated via the generated simulation models, and the corresponding simulation results together with decision makers' judgments on the criteria are used to select the best system design via AHP. A best alternative search (BAS) procedure is proposed for the adopted AHP approach to search for the best system design against ranking impreciseness caused by simulation randomness. At the high level, the proposed framework focuses on the optimal supply chain decisions for early order commitment (EOC) to reduce the amortized production capacity cost. EOC is a supply chain collaboration mechanism, where the grafted seedling producer encourages the vegetable growers to commit their orders earlier than their regular ordering times by providing certain benefits (e.g., price discount). Based on the optimal design of a grafted seedling production system and the corresponding production cost obtained at the low level, we first derive analytical solutions for the grafted seedling producer's optimal capacity, vegetable grower's optimal order quantity, and ordering time under a basic supply chain structure (i.e., single-seedling producer and single-vegetable grower). We then introduce capacity competition by extending the basic structure to a multi-vegetable grower structure. The existence of the N-person game equilibrium and the corresponding relationships between the grafted seedling producer's profit and the vegetable growers' early order decisions are provided. In addition, a capacity reservation mechanism is proposed for the seedling producer to motivate the vegetable growers to release order information in advance. To identify the convergence of the vegetable growers' ordering times, a Cellular Automata simulation model is developed, where each vegetable grower is modeled as a Pavlovian or greedy agent making an ordering time decision so as to receive the higher profit over iterations. The proposed framework is demonstrated for grafted seedling supply chains in North America. The experiment results reveal the benefits of the proposed framework in reducing the grafted seedling cost, as well as in increasing the entire supply chain's profit.

Abstract:

The global use of resources such as materials, energy, and water has surpassed sustainable levels by many accounts. The research presented here was explicitly normative in its aim to improve the understanding of, and make sustainable change toward highly systemic issues of resource management. The core methods chosen to work toward this aim were bottom up action research procedures (including stakeholder engagement processes) and industrial ecology analysis tools. These methods were employed and tested in pragmatic combination through two of the author’s case study projects. The first case study, performed between 2009 and 2012, employed a multi-stakeholder process aimed at improving the cycling of construction and demolition waste in the Stockholm region. The second case study produced a strategic tool (Looplocal) built for facilitating more efficient regional industrial resource networks. While the highly participative aim of the cases required a larger contribution of resources than that of more closed studies, it is arguable that the efficacy of approaching the project aims is improved through their employment.

Full text

Abstract:

The primary objectives of this research are formulation and evaluation of an improved batch-means procedure for steady-state simulation output analysis. The new procedure yields a confidence interval for a steady-state expected response that is centered on the sample mean of a portion of the series ofsimulation-generated responses and satisfies a user-specified absolute or relative precision requirement. We concentrate on the method of nonoverlapping batch means (NOBM), which requires the sample means computed from adjacent batches of observations to be independent and identically distributed normal random variables. For increasing batch sizes and a fixed number of batches computed from a weakly dependent (phi-mixing) output process, we establish key asymptotic distributional properties of the vector of batch means and of the numerator and squared denominator of the NOBM -ratio, where the terms of the expansion are estimated via an autoregressive--moving average time series model of the batch means. An extensive experimental performance evaluation demonstrates the advantages of ASAP versus other widely used batch-means procedures.

Abstract:

Industrial development at a regional level demands an ability to create productive cross sector collaboration. This thesis is about how such interorganizational collaboration can be constructed. Based on studies of three collaborative efforts taking place in the same region at the same time, I set out to answer the following main research question.

How can regional actors collaborate to support development in enterprises?

In the theoretical part of the thesis, I address the discourses on industrial development with an emphasis on the collaborative aspects. Three approaches that all heavily influence the current thinking and policymaking in this field are discussed. The first is what may be labeled the regional-development orientation associated with industrial districts and flexible specialization after Piore & Sabel (1984), mainly within the discipline of industrial geography. The second main contribution to the discourse on industrial development is the work of Porter (1990) and his followers. Typical for these two main contributions is that they circle around various collaborative constructs at a systemic or macro level (e.g. networks, industrial clusters) and in essence argue for the centrality of interorganizational collaboration in fostering industrial development. What they both lack, however, is considerations of how the desired collaborations can be created, i.e. they lack a development perspective that addresses the collaborative processes essential to practical development.

The third tradition or approach is associated with public planning for development. It takes the public actors as a point of departure in discussing how industrial development may be advanced. Within certain traditions of public planning associated with community development, a much clearer emphasis is put on broad regional participation and concrete means to involve various actors in collaborative planning efforts. I argue that in order to develop industry, a greater emphasis on “how” is needed, and I question the adequacy of a planning logic in this respect.

The broad support for collaborative strategies, but inability to contribute beyond declaring its importance, leads me to the main theoretical chapter where I address the issue of collaboration. Collaboration between organizations is viewed as a general approach to addressing shared problems, where industrial development is one such problem-complex. In conceptualizing collaboration, I give special attention to social ecology (e.g. Trist 1983) as a framework for interorganizational development. Organizing collaborative domains and collaborative processes are the two main foci of the chapter. I criticize the linear process models and develop the interactive dimension of collaborative processes as an alternative. This chapter ends in an expansion of the main research question into the following issues.

1) the organizing of collaboration

2) the processes of collaboration

3) the regional dimension of collaboration

4) the role of public actors

In part three of the thesis I present the case material covering 5+ years of development trajectories. The Joint Project, the Wood Centre and the Electronics Committee all have central features in common. All the three cases address competence development in enterprises, and they do it through collaboration between enterprises, the educational system and country representatives, however in clearly different ways. Moreover, the cases unfold during the same time period in the same country. Theses similarities give special access to the understanding of collaborative development processes by comparing across the cases.

Analysing and discussing the three development trajectories in part four of the thesis lead me to the last chapter, where my conclusions and contributions to the literature are presented. On the issue of organizing, several contributions to collaborative theory have emerged during the research process. I criticize the prevalent sequential and rather mechanistic contributions in the current literature, and I argue for a more dynamic and rather mechanistic contributions in current literature, and I argue for a more dynamic and iterative understanding of organizational issues. In a regional landscape where legitimacy, the building of trust and the development of relationships are at the core of feasible strategies for change, roles, functions and organizational forms need to be understood in a relational and dynamic perspective. This included regarding convening as an ongoing process throughout the lifespan of a collaborative effort, and to understanding the issue of organizing as a process of ongoing reconstruction, rather than a once-and-for-all construction of an organizational unit. As an alternative to the prevailing process models. I have developed principles of interactivity to characterize dynamic and evolving collaborative relationships based on a democratic value stand.

I have developed the regional dimension of collaboration by introducing new concepts (partial domain, sub-domain and triple connectedness), as well as developing the meaning of previously introduced concepts (infrastructure for change). I suggest the concept of a regional infrastructure for change as the conceptual bridge between industrial geography, collaborative theory and an action research oriented approach to industrial development. While the study does not fully discuss the role of public actors, it clearly argues the importance of a proactive role, and discusses some dilemmas with such a role. I emphasise the importance of regional autonomy, the recognition of public-public collaboration a part of industrial development, and the challenge for public actors of moving back and forth between the two different logics associated with, respectively, bureaucracy and horizontal collaboration.

Abstract:

Setred är ett Europeiskt teknikinnovationsbolag som har utvecklat en 3D-displayteknik som inte kräver glasögon eller headtrackingutrustning. Teknologin har blivit integrerad i en autostereoskopisk 3D-arbetsstation vid namn Clariti som har tagits fram specifikt för medicinsk användning inom kirurgi och kirurgisk planering. I sitt ursprungliga utförande är arbetsstationen ganska stor och tung. Detta är inte ett hinder när den väl är på plats på sjukhuset där produkten är tänkt att användas, men utgör ett stort problem för säljarna på företaget vars främsta uppgift är att åka runt och presentera arbetsstationen för potentiella kunder. Ett examensarbete har därför utförts på Kungliga Tekniska Högskolan (KTH) i Stockholm, för att utveckla en demoversion av arbetsstationen Clariti. Huvudsyftet med demo-arbetsstationen är att förenkla transporten av enheten för säljteamet på Setred och samtidigt kunna demonstrera funktionaliteten hos Clariti på ett tillfredsställande sätt.Uppgiften utfördes av två studenter på inriktningen industriell design på KTH i tätt samarbete med företagsrepresentanter från Setred. Projektet pågick under 20 veckor med arbete på heltid mellan januari och juni 2012. Huvudsakligen utfördes arbetet på Setreds kontor i Stockholm.Projektet följde en fördefinierad produktutvecklingsprocess som började med en litteraturstudie och gick vidare med en problemundersökning med hjälp av semistrukturerade intervjuer, fokusgrupper och kundresor. När problemen med den ursprungliga designen hade blivit identifierade togs flera koncept för en demo-arbetsstation fram i form av skisser och enkla 3D renderingar och presenterades för representanter på företaget. Koncepten diskuterades och analyserades och de bästa valdes ut för vidareutveckling. Samtidigt togs en kravspecifikation fram för demo-arbetsstationen som listade de viktigaste kraven på konstruktionen. De mest lovande koncepten utvecklades till enkla CAD modeller där kärnstrukturen av Claritis 3D skärm integrerades i modellerna. Det bästa konceptet valdes senare för vidareutveckling till en detaljerad CAD modell med hjälp av metoder i användarcentrerad design och ergonomiska riktlinjer som stöd. Simuleringar utfördes på den mekaniska konstruktionen för att verifiera stabiliteten i strukturen och underlätta materialval.Projektet resulterade i en detaljerad CAD modell av en demo-arbetsstation som är anpassad för enkel och smidig transport och hantering. Den nya arbetsstationen har en minskad vikt och en modulär design som ger större transportmöjligheter.
The work presented in this Master Thesis was performed at Setred AB in Stockholm and at the Department of Machine Design at the Royal Institute of Technology in Stockholm. The project was carried out between January 2012 and June 2012 as the final element in our Master of Science Degree within Industrial Design Engineering.We would like to thank all people involved for their time and dedication to the project. Great thanks to the Setred staff from all three offices for all their feedback, knowledge and participation in the project. A special thank you goes to Martin Wahlstedt, our supervisor at Setred, for guiding us through the course of the project and providing us with invaluable information and feedback on our designs.Special thanks to our supervisor Carl Michael Johannesson, our supervisor at KTH, for tutoring and support, and also to our classmates at KTH for the feedback that was received during the seminars and workshops.Finally we would like to thank our families and friends for all their support during the project.

Abstract:

The construction industry is generally considered a non-innovative and conservative industrial sector compared to other industries. Measurement of innovation is a very difficult task and it has very complex product system. This study aims to describe the role of innovation and development activities within the Finnish construction industries. Additionally, it explores the logic of innovation in construction and patent creation in the Finnish construction industry by sectors. It evaluates the correlation of patent creation and Research and Development (R&D) investment. The research also covers the citation of Finnish construction patents. A major conclusion was drawn from the empirical data analysis followed by the qualitative analysis approach. However, both qualitative and quantitative techniques have been used for the data analysis. Whole thesis was completed by two-fold process: 1) analysis of construction patent data from 2004–2014 and 2) semi structured interview with the expert of the construction companies. The result of the research focuses on several aspects of the innovation and development activities. However, the main result demonstrates that the Finnish construction industry have understanding of innovation and development activities as a second factor after price in the bidding process. They are more interested in the innovation activities. Similarly, it also reveals that mainly, patents are created in the construction ‘Product sector’ followed by ‘Building’, ‘HPAC’ and ‘Infra’. The result also reveals that organizational innovation and market innovation have taken place more than product innovation and process innovation. Finally, result shows that the R&D investment and patent creation do have a positive correlation; and R&D budget investment per patent varies from company to company. The major limitation of this study is in finding the correlation of R&D investment and patent creation because of the currency conversion rate. The currency conversion rate on the day of analysis is used for this research which might fluctuate. Also, some of the companies do not indicate their exact R&D budget in their public file. So based on the available information R&D budget is calculated and overall picture has been presented in the research.

Abstract:

According to the USDA Economic Research service, farm-level prices are on the decline. This decline in prices particularly hurts smaller scale operators with many needing to rely on off-farm income in order to ensure they remain in operation. This thesis studies two problems of key interest to the Southeast region and the State of Kentucky by investigating dairy management practices and the environmental benefits of hemp production. As dairy prices have been on the decline and dairy co-ops have tightened their restrictions on somatic cell count (SCC) levels, dairy farmers and farm managers must decide the best course of action for maintaining milk quality in order to maintain their contract and profitability. Maintenance decisions as well as factors like sanitation and animal living conditions can all contribute to bulk tank SCC and depending on the type of incentives or penalties instituted by the co-op they can have an impact on net farm income. The objective of the dairy study is to determine which dairy management practices have the largest impact on SCC levels. Industrial hemp is produced worldwide. Historically, the major producers of hemp have been China, Europe, and Russia. In 2014, the passage of the Farm Bill opened the door to the production of Industrial hemp through the development of state pilot programs. Then the 2018 Farm Bill removed industrial hemp from the Scheduled Drug list. This has further expanded the opportunities and excitement for this crop. The plant’s versatility and the variety of products that can be made from it are coming to light. Sustainability is one of the key attributes touted concerning industrial hemp. Specifically, in the state of Kentucky, it is expected to be a replacement for tobacco and other traditional crops. However, how does the crop compare to tobacco production in terms of sustainability? The objective of the hemp study is to develop a life cycle analysis on the planting and harvesting of hemp and compare its impacts to more traditional crops.

Abstract:

A 500Kg, self-contained biped robot, named Roboshift, has been conceived and tested to investigate issues associated with the control of industrial scale biped robots. This project represents the first credible attempt to build a heavy weight autonomous biped robot. The recent expansion in humanoid robot development has highlighted advances made in anthropomorphic biped technology. Current research into speech recognition, vision systems, laser topography, artificial intelligence and electroactive polymers will ultimately achieve an Android capable of human like actions and thought processes. Justification for this most demanding and expensive research is based on philanthropic models that suggest these robots will attend to the bedridden, or replace humans in dangerous areas. However, the cost of a biped robot when compared to that of a wheeled or tracked vehicle restricts commercialisation for these applications. As well, the size and working capacity of current humanoid robots is not compatible with the heavy lifting requirements found in such environments. It is proposed that only biped robots of an industrial scale, possessing a capacity much greater than that of a human, will be of commercial value in the future. Typical applications may include the handling of materials in confined or uneven terrain, where a forklift or other commercially available materials handling equipment would be unsuitable. For example, field handling in military, mining or geological environments. Minimal research has been conducted into the realisation of such a device, which presents challenges in terms of the magnitude of dynamic forces produced and of the systems required to control the robot in real-time. Review of relevant literature reveals that little research has been completed in this field. Therefore, operational characteristics for an industrial scale biped robot are defined. The design then details the structure and integration of mechanical, hydraulic, and electrical systems. Roboshift is powered by an internal combustion engine and is the first biped robot with a capacity for extended operation. Modelling was conducted to determine joint trajectories, power requirements, hydraulic flow parameters and dynamic characteristics. The robot is controlled by a distributed, hierarchical system comprising sixteen microprocessors, a control computer acting as the midbrain and a communications computer acting as the central nervous system. Sensors measure attitude and heading (vestibular system) as well as ground reaction forces and joint angles (propreoception). The control strategy is based on feed forward trajectories generated by inverse kinematic analysis. Corrections to trajectories are made in real time by higher level routines running on the main control computer. Joint position is achieved by local feedback control. Software for the robot was written in the C language. Experimental results are presented detailing the performance of the robot in comparison to theoretical analysis. After construction and testing of actuators and sensors, calibration software was tested successfully. Once calibrated, the robot was lowered to the ground where the active balance software was able to control the robot in the frontal and sagittal planes. Frontal sway software was tested with mixed success as natural oscillation of the structure, which was not detectable by the control system, led to erroneous force data. Detailed dynamic modelling was then completed to determine the causes of oscillation in the robot. The modelling led to the formulation of a control strategy where non-collocated sensors are used to measure link strain as a feedback to a modified proportional controller. The project has demonstrated that an industrial scale biped incorporating an internal combustion engine and hydraulic power system is feasible.. Analysis presented proposes that as the height of a biped robot increases, the expected elastic deformation of the structure increases as the cube of the height, making control extremely challenging. A strategy for the control of heavy-weight robots is suggested It is also proposed that technology incorporated in current humanoid robots can not be scaled to control industrial bipeds.

Abstract:

Research into the use of project management procedures has mostly been directed at the private sector of the construction industry, despite the fact that the public sector contribute almost half of the UK's construction output, in the repair and maintenance sector of the construction industry. Indeed, since the introduction of compulsory competitive tendering (CCT) in 1980, the public sector has had to carry out a continually increasing proportion of their work under competitive conditions, bidding for work along with private sector construction contractors. This thesis focuses on the use of project management procedures in both private and public sector construction contractor organisations, looking at the utilisation of a number of different project management procedures, including organisation profile, project planning and control, quality management, and human resource considerations. It is believed that all these aspects must be considered together, if an accurate picture of an organisation's approach to the management of projects is to be achieved. The argument employed throughout this study is that where project management procedures are adopted in the management of projects, a project manager will have the potential to better manage the project, than would otherwise be the case. Empirical research was carried out using both a quantitative approach (structured mail questionnaire) and a qualitative approach (semi structured interviews). 100 responses were received in all, 80 to a questionnaire for construction contractors, 63 in the private and 17 in the public sector. Personal interviews were carried out with 20 project managers. Analysis of the data investigated the use of a number of different project management procedures and identified differences in their use between private and public sector contractors. The results showed that despite tendering for and carrying out work in the same market area, there were notable differences in the use of project management procedures between private and public sector construction contractors. In the main, private sector construction contractors utilised project management procedures to a greater extent than contractors in the public sector; however, in many instances the use of such procedures could hardly be described as extensive. For example, planning in many instances did not extend to the monitoring and control phase once projects were underway; the 'baseline' plan was effectively disregarded for updating project status, particularly so in the public sector. Despite the powerful nature of performance monitoring techniques, such as 'earned value analysis', little use was made of them. This general lack of project control was further exacerbated because both private and public sector construction contractors tended to operate separate 'stand alone' project costing systems, remote from those used for project planning and control purposes. There was a strong commitment to quality in both the private and public sectors. However, a noticeable difference wast that the private sector tended to apply their quality management systems to all areas of their business, whereas, the public sector normally only operated such systems for restricted areas of work, when compared to the 'overall' project. Of further concern was that both private and public sector construction contractors took account of the 'human' element to a much lesser degree than issues of time, cost or quality, even though they said they viewed it as important. Notwithstanding the existence of project management procedures for many years, there was a common lack of awareness and under utilisation of all but the most straightforward procedures in both sectors of the industry. This was especially so within the public sector. Essentially, private and public sector construction contractors must initiate familiarisation and training programmes within their organisations to enable their project managers to access the best project management 'tools' available to assist them in their projects.

ENGLISH ABSTRACT: Skills development is a crucial element in improving the effectiveness with which organisations operate in the current global arena. The level of skills of employees in any organisation should be of significant managerial concern. The principal aims of this study is firstly to investigate the success achieved in skills development initiatives in the agricultural sector in South Africa and secondly to develop a theoretical framework of important individual and organisational variables for skills development in agriculture. Management on farms need to develop the skills of their employees in order to ensure effective adaptation to changes in the sector. A strong need for development also exists among South Africans working in the agricultural environment, as the sector is rapidly modernising and the people employed in this sector often possess low skill and literacy levels. The key question is whether the skills development strategies and initiatives of farms are conducive to successful human resource development, in light of the specific individual and organisational context. A multiple case study research design was used, exploring the various ways in which six different farms approach skills development and the variables which impacted on the success thereof. These approaches and effects are compared to the literature and across cases to move towards the development of a skills development framework applicable to the unique agricultural context in South Africa. Data collection included primary (semi-structured interviews with employees and management) and secondary (background and administrative) information to comprehensively describe each case. Pattern matching was used to determine common trends between the cases and illustrate them in terms of a conceptual framework. General support was found across the six cases for the complex and extensive framework of variables. The following individual variables were found to have an impact on the effectiveness of skills development: ability to learn, motivation to engage in and transfer training, attitude to skills development, locus of control, and perceived ability to learn. Organisational variables which affected the effectiveness of skills development included the following: labour relations, organisational strategy, culture, climate, and systems. Many of these variables comprised a number of sub-variables, which were also shown to be relevant in the framework. Variables in the individual and organisational frameworks were also found to demonstrate interactive effects within and across framework boundaries. The results of the study serve as thought provoking reading for managers, which could stimulate critical thought and an inquisitive attitude to skills development on their farms. In general, training and development was approached in a very informal manner in terms of strategy, goals, and practice. Managers can surely benefit from adopting greater formalisation in these aspects as it would ease the process of planning, implementing, and evaluating training. In certain instances additional variables or interrelationships were identified for future study. The establishment of the framework of variables serves to inform future research: it represents a point of departure for research in a critical field where little recent research has been published.
AFRIKAANSE OPSOMMING: Die ontwikkeling van vaardighede is 'n kernbelangrike aspek om die doeltreffendheid waarmee organisasies in die huidige internasionale speelveld optree te verbeter. Die vaardigheidsvlakke van werknemers in enige organisasie behoort van kernbelang te wees vir bestuurders van sulke organisasies. Die hoofdoel van hierdie studie is dus eerstens om die mate van sukses met vaardigheidsontwikkelingsinisiatiewe in die landbousektor te ondersoek en tweedens om 'n teoretiese raamwerk van die belangrikste individuele en organisatoriese veranderlikes vir vaardigheidsontwikkeling in landbou te ontwikkel. Die vaardigheidsvlakke van werknemers in die landbousektor moet deur die werkgewer ontwikkel word om te verseker dat effektiewe veranderinge in hierdie sektor plaasvind. Daar is 'n besonder sterk behoefte aan vaardigheidsontwikkeling onder werknemers in die landbousektor van Suid-Afrika , aangesien die sektor 'n snelle moderniseringsproses ondergaan, maar die werknemers in baie gevalle oor besonder lae vaardigheids- en ontwikkelingsvlakke beskik. Die vraag bestaan of die strategieë en inisiatiewe wat deur die werkgewer geïmplementeer word wel aanleiding gee tot suksesvolle menslike hulpbronontwikkeling, gegewe die spesifieke individuele en organisatoriese konteks. Deur gebruik te maak van veelvoudige gevallestudies as navorsingsmetode, is daar gekyk na ses verskillende plase se benadering tot opleiding, asook die impak en sukses van hierdie opleiding. Hierdie benaderings en invloede word vergelyk met die literatuur en tussen gevallestudies met die oog op die ontwikkeling van 'n vaardigheidsontwikkelingsraamwerk spesifiek binne die unieke konteks van die Suid-Afrikaanse landbousektor. Data-insameling behels primêre inligting (semi-gestruktureerde onderhoude met werknemers en bestuur), en sekondêre inligting (agtergrond- en administratiewe) om elke geval omvattend te beskryf. Patroonpassing is gebruik om algemene tendense tussen die gevallestudies te identifiseer en vervolgens die gevallestudies met die konseptuele raamwerk te vergelyk. Die ses gevallestudies het die komplekse en omvattende raamwerk van veranderlikes in die geheel ondersteun. Resultate toon aan dat die volgende individuele veranderlikes 'n klaarblyklike impak gehad het op die doeltreffendheid van opleiding en ontwikkeling: die vermoë en motivering om te leer en vaardighede oor te dra; die houding teenoor opleiding ontwikkeling; die lokus van beheer; en die waargenome vermoë om te leer. Die doeltreffendheid van opleiding en ontwikkeling is ook deur die volgende organisatoriese veranderlikes beïnvloed: arbeidsverhoudinge, organisatoriese strategie, kultuur, omgewing en stelsels. Die sub-veranderlikes van die individuele en organisatoriese veranderlikes is ook as relevant binne die raamwerk aangedui. Verder is die voorgestelde verwantskappe tussen veranderlikes (binne sowel as oor die grense van die individuele en organisatoriese raamwerke) ook ondersteun. Die resultate van hierdie studie dien as insette vir bestuurders om kritiese denke en 'n ondersoekende ingesteldheid teenoor opleiding en ontwikkeling op hul plase te stimuleer. Opleiding en ontwikkeling is oor die algemeen op 'n baie informele wyse geïmplementeer ten opsigte van strategie, doelwitbepaling en uitvoering in die praktyk. Bestuurders kan baat vind by die formalisering van bestaande praktyke omdat dit die proses van beplanning, implementering en evaluering van opleiding en ontwikkeling kan vergemaklik. Addisionele veranderlikes en interverwantskappe is geïdentifiseer vir verdere navorsing. Die samestelling van die raamwerk van veranderlikes dien juis as uitgangspunt vir toekomstige navorsing in 'n kerngebied wat min aandag in navorsing geniet.

Abstract:

There is a widespread view in the relevant academic literature that the UK's economic performance would be better if the situations of its engineers, engineering and manufacturing were more favourable. In particular the apparent dominance of accountants and financial expertise and the relative lack of influence of engineers and technical and productive expertise in manufacturing companies have been much discussed. As a presumed consequence of this, and despite a shortage of empirical evidence, engineers are apparently marginalised in managerial hierarchies, particularly in the most senior positions, and there is a subordination of technical to financial and other commercial priorities and objectives. The role of engineers in construction, however, has been virtually ignored despite the sector's economic importance and the relatively large numbers of engineers employed in it. The author and his supervisor conducted 25 interviews with representatives of the engineering and other main organizational professions, management institutes, employers' associations and a small number of academic and policy researchers. Their aim was to help identify the main issues which were relevant to UK engineers. From these interviews, and from reviewing the literature about engineers and management, the author decided upon the aims of the research. These were: to examine how engineers in manufacturing and construction feel about their influence and career prospects vis-ä-vis the members of the other professional groups with whom they work; to explore the perceptions of management-level people in industry about the managerial abilities of engineers and their colleagues; to investigate how engineers feel about the trade unions and professional associations which represent many of them; to examine the views of engineers about issues surrounding it engineering education and the importance which employers place on formal engineering qualifications; and to determine how engineers feel about the social place of their profession and about their levels of remuneration. Eighty-two interviews were conducted with engineers and their colleagues in three industrial sectors: mechanical and electrical engineering, chemicals, and construction. In manufacturing the main functional groups seemed to enjoy more constructive relationships than was apparently the case during the 1970s and 1980s. Although they appeared to form an influential group, the author found little evidence to support the notion that accountants dominate manufacturing companies, and they were generally considered both by themselves and by engineers and other colleagues to be performing a support function. Engineers appeared to enjoy the widest range of career opportunities of all the main management level groups, with the possible exception of chemists in chemicals. These opportunities included promotion to the boardroom. However some respondents felt that engineers needed to become rather less involved in the technical aspects of their work to advance their careers. In construction it was found that the main professional groups appeared to operate in varying degrees of mutual opposition. Their roles and influence depended to a large extent on the nature of the product and on the method of contracting chosen by clients. Architects in building and design engineers in civil engineering appeared to have lost their dominant positions in the management of projects. In both cases the main beneficiaries were contracting companies, which are staffed at management level mainly by engineers, and to a smaller extent quantity surveyors. 111 The author found no evidence to support the view that engineers are superior or inferior to other professional groups in terms of their `management' abilities, although the latter are clearly very difficult to measure. Only three of sixty-one engineer respondents were trade union members and most engineers appeared to believe that trade union membership was incompatible with their professional and/or managerial identities. About half of the engineers in the sample were members of professional engineering associations but this varied between sectors, as did the importance attached by respondents and their employers to chartered status. The engineer respondents tended to believe that their profession was poorly organised and ineffectual. Although employers appeared to rely heavily on formal qualifications to distinguish between different grades of technical staff, most respondents felt that engineering degrees needed to more practically oriented. The social standing of engineers and engineering was generally considered to be low. Many engineers believed that the general public neither understood nor appreciated fully what they did. However, engineers in the manufacturing companies in the study were generally satisfied with their levels of remuneration, although most respondents in construction felt that they were underpaid. The thesis concludes by arguing that when taken together with other evidence, particularly the many useful developments in education for management, the results suggest that the prospects for the UK economy might be considered to be improving, and certainly better than they were during the 1970s and 1980s.

Abstract:

The purpose of this study was to investigate the incidence, frequency and severity of accidents in Arizona secondary agricultural education programs. Data were obtained by questionnaires sent to secondary school teachers of agricultural education in Arizona from February 2, 1991, to April 15, 1991. Among the teachers who reported one or more accidents, a pattern of accidents was observed over the period (1989-90 school year) studied. Cuts and burns were the most frequent accidents in the programs, followed by bruises and scratches. Incidents such as loss of hammer head and disintegration of grinder wheel pose great danger and, therefore, require the attention of teachers and administrators as well. It is hoped agricultural education teachers and students, through this study and others similar to it, will be able to gain insight into the patterns of accidents occurring in their labs and, most of all, stress adherence to safety guidelines.

Abstract:

Hydrogen sulfide (H2S) is a gas commonly produced in manure pits. When the manure is disturbed through manure handling activities such as pressure washing, agitating, and pumping out manure, H2S is released. During these activities H2S concentrations increase quickly and reach hazardous concentrations. Many fatalities from high H2S concentrations during manure handling activities have been reported internationally as well as in the Midwest. Occupations in general industry that have identified the potential for high H2S concentrations use monitors to warn worker of high H2S concentrations. However, in agriculture the adoption of H2S monitors is low. To encourage farmers to adopt H2S monitors, interactive training materials were created. Displays were deployed to locations that farmers frequent such as agricultural stores, extension offices, and cooperatives. Agricultural stores are defined here as locations that sell agricultural supplies wholesale, or retail, and services. These displays contained educational materials, two H2S monitors, and two types of bump testing gas for farmers to use. Along with the display passive trainings, six in-person trainings were completed where participants filled out surveys. The survey asked questions about the farmers knowledge and use of H2S monitors, likelihood of purchasing a H2S monitor in the future, easiest bump testing gas to use and the one preferred for future bump testing, and the location that farmers would prefer to go to for bump testing and monitor education. Survey participants were placed into two groups: livestock producers and commercial manure applicators. A total of 43 surveys were completed by these groups. The majority of both livestock producers and commercial manure applicators knew what H2S monitors were, but less than half of the participants actually used H2S monitors. Outreach focusing on H2S monitor use and maintenance should be continued. Hydrogen sulfide monitor use and maintenance training had the more attendance when added to an already existing training or meeting such as the manure applicator trainings or livestock producer meetings. In the survey, livestock producers and commercial manure applicators were asked the easiest type of bump testing gas where both groups chose that the calibration gas is easiest to use. When prices were included in the survey question for both bump testing gas systems, many more of livestock producers and commercial manure applicators responded that they could see themselves using neither in the future. Price of bump testing systems ($130-$220) can be a potential barrier for some farmers to not bump test their monitors, it would be beneficial for multiple farmers to share one bump testing system. Putting a bump testing system in at agricultural stores, cooperatives and extension offices would allow many farmers to use it. Commercial manure applicators reported that they had no preference in future locations for bump testing and monitor advice between the agricultural store, cooperatives, and extension offices. Livestock producers preferred agricultural stores a little more than cooperatives and extension offices, but all three locations should be used for continuing H2S monitor education. In our study agricultural stores had the most bump tests recorded, bump testing gas used, they purchased a bump testing system for their customers.

In the 21st century, millions of older adults in the United States are coming out of retirement to work. In some cases, inadequate benefits and savings force them out of retirement, especially when they or their spouses experience costly health problems. In other cases, older workers “unretire” after losing loved ones, or as they experience social loss and disengagement. These older workers seek companionship through work. Although many older workers enjoy aspects of the jobs they attain in unretirement, their compensation is often insufficient, forcing some of them to perpetually delay re-retiring. Such unretirement reverses decades of movement toward greater and earlier retirement for older adults and significantly affects cultural meanings of old age. Focusing on six different worksites in Kansas, I examine how older workers and employers socially and culturally re-construct age. Evidence from ethnographic observation and thirty-three in-depth interviews with older workers and their employers suggest that employers view older workers’ agedness as an asset they can exploit to cut costs and boost profits. In sharp contrast, many older employees’ younger co-workers and clients treat them as if agedness diminishes their competence and relevance in the workplace. This is particularly true for women, who struggle more than their male colleagues to fend off the negative labels some younger co-workers and clients attempt to apply to them. Ultimately, I find that old age is a valued human resource for employers, making older employees “ideal workers,” but the cumulative effects of older workers’ interactions in the workplaces tend, on balance, to devalue older age. Notably, the forces that promoted positive constructions of older age tend to be rooted in exploitation. Employers who idealize older workers do so to squeeze as much unpaid labor power out of them as possible. When older workers resist exploitative work assignments, they often become subject to negative labeling, as opposed to other kinds of “problem worker” labeling that younger workers might face. By specifying the mechanisms that produce harmful versus helpful constructions of age at work in traditional retirement years, my study contributes to the growing body of research on the relatively new phenomenon of unretirement in the United States.

Abstract:

Background: The burden of fatal and non-fatal injury for the New Zealand construction industry is larger than most other industrial sectors. Injury preventions efforts for construction have however been hampered because of insufficient, industry-specific, surveillance data that is essential for the effective targeting and evaluation of interventions. Aim: This thesis aimed to describe and test a feasible framework of Injury Surveillance for the New Zealand construction industry. Accordingly, the specific objectives to accomplish this aim were: To identify an optimal surveillance dataset for New Zealand construction injuries; To assess potential sources of data and collection methods; To describe an ideal study design for undertaking injury surveillance; To implement an operational design based on industry stakeholder input; To undertake and evaluate an injury surveillance trial; and To suggest how a viable surveillance system could be permanently established. Method: A trial injury surveillance system was developed by identifying known construction injury risk factors from the literature, reviewing the data collection practices of the New Zealand industry and other potential data sources and consulting with industry stakeholders about the most feasible collection methodology. This surveillance framework was then tested by combining national data from routine Government sources and data from 3 construction companies that employed approximately 720 workers between them. National construction injury data was obtained from the Accident Compensation Corporation, the Department of Labour and the Injury Information Manager. The trial Surveillance System was then evaluated in terms of its ability to collect the full range of an optimal dataset, the quality and completeness of information actually collected, the ability to identify and monitor injury priorities for the industry, and the future viability and acceptability of this surveillance design to the industry. Results: A total of 468 medically treated injuries were recorded by the participating companies, with 15 (3.2%) considered to be Serious Harm injuries as defined by the Health and Safety in Employment Act. The level of data completeness across companies was especially low, with on average 18 out of 34 data fields (53%) completely unrecorded. The data from one company was sufficiently complete (i.e. 63% across all fields) to allow individual risk factor analyses to be conducted, whereas the absence of complete denominator data prevented the completion of the same analyses for the other two companies. Viewed overall, Government agency data was sufficiently detailed to estimate national longitudinal trends, injury agency and mechanism priorities for specific occupations and industry subsectors, and allowed a rudimentary evaluation of a national intervention programme. However, questions about data accuracy, completeness and under-reporting were raised for each of the Government data sources used. Conclusions: Using data entirely from Government sources appears to be the most immediately viable framework of Injury Surveillance for the New Zealand construction industry. As such, the relevant range of analyses demonstrated by this study should be continued, expanded and improved. In contrast, obtaining injury surveillance data from companies in the manner that was tested does not appear to feasible, given the difficulty in recruiting companies and the poor data completeness of those companies that did participate. However, the increased range of prevention targets identified by the company that did largely contribute data as intended, demonstrated that company surveillance had merit relative to existing procedures. Suggested steps toward implementing viable construction injury surveillance within New Zealand are outlined, including a recommendation to the industry�s Health and Safety organisation, SiteSafe, to investigate the most feasible data collection protocol for its members.

Dentre diversos casos de SI no mundo, destacam-se o caso do Parque industrial de Kalundborg na Dinamarca e o National Industrial Symbiosis Programme â NISP na Inglaterra. No Brasil, A FederaÃÃo das IndÃstrias do Estado de Minas Gerais â FIEMG coordena o Programa Mineiro de Simbiose Industrial â PMSI, versÃo adaptada no programa de simbiose britÃnico. Foram entrevistadas representantes de sete empresas de diferentes setores e regiÃes do estado alÃm de quatro atores: a FederaÃÃo das IndÃstrias do Estado de Minas Gerais, o ÃrgÃo ambiental, um sindicato setorial e uma associaÃÃo de catadores. A anÃlise dos dados procura identificar os elementos presente no framework de Spekkink (2014): Contextos, Capacidades Institucionais, Atores, InteraÃÃes e Redes de Simbioses na realidade mineira. Os resultados apresentam como a FIEMG utiliza suas capacidades institucionais na promoÃÃo do PMSI; como os atores sÃo envolvidos na simbiose atravÃs de suas crenÃas, desejos e oportunidades; como ocorrem as interaÃÃes entre esses atores e os resultados em forma de rede de simbioses. Como conclusÃes, esta pesquisa constata a importÃncia do promotor da SI e sua articulaÃÃo com os atores, principalmente os sindicatos setoriais; a fraca influÃncia dos contextos de governanÃa, econÃmico e fÃsico na promoÃÃo do PMSI; a fraca participaÃÃo de atores como o ÃrgÃo ambiental no processo de simbiose e as barreiras que surgem nas trocas entre as empresas.
The main objective of this study is to understand how the activities developed by FIEMG â the Federation of Industries of the State of Minas Gerais, have built and mobilized the capacities for the development of Industrial Symbiosis. Industrial symbiosis - IS occurs through physical exchange of materials, energy, water, and/or by-products among (geographically close)industries in a collective approach to increase competitive advantage, thus improving the environmental performance of companies as well as reducing their total costs (Chertow, 2000; Chertow, 2007). Among several cases of IS in the world, we highlight the case of Kalundborg Industrial Park in Denmark and the National Industrial Symbiosis Programme - NISP in England. In Brazil, FIEMG coordinates the Mining Industrial Symbiosis Programme - PMSI, which is based on the British symbiosis program. Representatives of seven companies from different sectors and regions of the state were interviewed, as well as four actors: the Federation of Industries of the State of Minas Gerais, the environmental agency, an employerâs association and a cooperative of waste pickers. Data analysis aims at identifying the elements present in Spekkink framework (2014) Contexts, Institutional Capacities, Actors, Interactions and Network of Symbiotic Exchanges in mining reality. The results show how FIEMG uses its institutional capacity to promote the PMSI; how the actors are involved in symbiosis through their beliefs, desires and opportunities; the way the interactions occur between these actors and the results as a symbiosis network. This study evidences the importance of the IS promoter and its connection with the actors, especially the employerâs associations; the little influence of governance, economic and physical contexts in promoting PMSI; the low participation of some actors, as the environmental agency, in the symbiosis process and the barriers that come from the exchanges between companies.

Abstract:

Safety is a continually significant issue in the construction industry. The Occupation Safety and Health Administration as well as individual construction companies are constantly working on verifying that their selected safety plans have a positive effect on reduction of workplace injuries. Worker safety is a large concern for both the workers and employers in construction and the government also attempts to impose effective regulations concerning minimum safety requirements. There are many different methods for creating and implementing a safety plan, most notably the Construction Industry Instituteâ s (CII) Zero Accidents Techniques (ZAT). This study will attempt to identify a relationship between the level of ZAT implementation and safety performance on industrial construction projects. This research also proposes that focusing efforts on certain ZAT elements over others will show different safety performance results. There are three findings in this study that can be used to assist safety professionals in designing efficient construction safety plans. The first is a significant log-log relationship that is identified between the DEA efficiency scores and Recordable Incident Rate (RIR). There is also a significant difference in safety performance found between the Light Industrial and Heavy Industrial sectors. Lastly, regression is used to show that the pre-construction and worker selection ZAT components can predict a better safety performance.

Abstract:

Construction materials cost estimation is considered one of the most important tasks in the development of project budget. Using material hedging to mitigate the risk of material price volatility is a new concept for construction companies.

This thesis matched material hedging with the fuel hedging application utilized by airlines. The weather hedging process was used as a precedent for material hedging application in the construction industry. This thesis developed a model to provide a step by step guidance to apply material hedging in the construction industry. Further, this thesis matched its model with the model presented by Macdonald (2013) and provided a lower level of detail to support actual implementation of material hedging.

Future work in this area could be the investigation of material hedging cost to decide if the hedging application is feasible. Also, validity and reliability of the model presented by this thesis should be investigated.

Abstract:

This dissertation explores the impact of international trade on the geographic location of manufacturing activities and on regional productivity growth patterns within countries. This study develops models of trade with monopolistic competition in the context of a two-region country. It also provides empirical estimates of the e ect of tari policy on the distribution of industrial activities and on productivity growth di erentials across Colombia's regions. The rst essay investigates the consequences of trade liberalization for the distribution of manufacturing activities between large and small cities. It presents an extension of the Melitz (2003) model of trade with monopolistic competition and heterogeneous rms where producers' location and export market participation decisions depend on their productivity. As a country's exposure to trade shifts, rms and output are reallocated between large and small urban areas. Data from Colombia's manufacturing sector lend support to theoretical predictions concerning tari reduction's impact on the repartition of industrial activities between metro- and nonmetropolitan areas in this country. The second essay extends the New Economic Geography, Footloose-Capital model to examine the e ect of commercial policy on the distribution of industrial activities between regions within a country. This study aims at distinguishing theoretical cases with regard to the nature of the trade policy change or to the source of asymmetry between regions. It shows that trade liberalization can have adverse consequences for the manufacturing sector of a small or isolated region under bilateral liberalization, but a positive impact under unilateral trade liberalization. The third essay adapts the Melitz and Ottaviano (2008) model of trade with monopolistic competition, heterogeneous rms, and variable mark-ups to analyze the relationship between trade openness, regional market size, and regional aggregate industry performance. It demonstrates that the impact of trade liberalization on aggregate industry productivity growth varies across regions as a function of regional market size and proximity to foreign markets. A larger region experiences a greater increase in aggregate productivity through intra-industry reallocation of market shares. Similarly, a region with better access to international markets enjoys a higher productivity growth from tari reduction. Empirical evidence is obtained from the Colombian manufacturing sector.

Abstract:

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.

Abstract:

Without an increase in cropland, agricultural efficiency must be tripled in the next 50 years to sustain the increased demand for food. Controlled environment agriculture (CEA) systems are likely to play an important role in the increase of agricultural efficiency. CEA systems, however, require constant observation because decisions must be quickly made when plants show signs of stress. A visual inspection system that uses a robotic camera system would permit visual access to inaccessible plants in a large hydroponics operation or allows an observer to remotely inspect plants for multiple small or remote CEA operations, whereas a dedicated CEA specialist would be beneficial but impractical under present conditions. This thesis presents a theoretical design for a plant inspection robot. The design parameters, design process, and the system specification necessary to satisfy the design constraints were examined for this system. The design analysis revealed that the major components of the plant inspection robot must be designed sequentially, starting with the imaging system. The imaging system design revealed that the system parameters were governed by illumination, shape and size of the object, and the desired detail. The motion system design was governed by velocity, acceleration, work area, and accuracy. An example design for a system used for visual inspection of 289 romaine lettuce plants was presented. This design was shown to be feasible from the theoretical perspective and could be built from commercially-available components, reducing development time and cost.
