Assessing Student Knowledge and Perceptions of Factors Influencing Participation in Supervised Agricultural Experience ProgramsLewis, Lauren Joanna 2012 May 1900 (has links)
The purpose of this study was to assess student knowledge and perceptions of factors influencing participation in Supervised Agricultural Experience (SAE) programs. This descriptive study was conducted in 120 randomly selected agricultural education programs throughout four purposively selected states representative of the National FFA regions. Within each state the programs randomly selected to participate were from FFA divisions characterized as having urban city-centers with outlying rural/suburban areas. Students in Florida, Indiana, Missouri, and Utah completed a researcher-designed questionnaire assessing knowledge and perceptions on factors influencing SAE participation. A response rate of 43.3% (N = 120, n = 52) was achieved, with questionnaires completed by 1,038 students. According to findings of this study 45.6% (n = 473) of the students participated in SAE programs, with most categorized as an entrepreneurship SAE and classified as a livestock project. Students could only identify at most three of five SAE categories, and those without a SAE program were either not or somewhat familiar with the five SAE categories. Students surveyed in Missouri and Utah appeared to have the strongest SAE knowledge. Each state appeared to have three main types of school resources available for use by student SAE programs. Student perceptions indicated that teachers did encourage all students to have a SAE program and apply for awards and recognition; however, most did not receive awards and recognition for their SAE program. Students reported receiving SAE help from their teacher on a monthly basis most frequently. Most students used a paper-based SAE record book which they updated weekly or monthly. Students on average received a total of nine to 34 days of classroom SAE instruction and a total of eight to 33 days of classroom recordkeeping instruction during enrollment in agricultural education courses. Factors such as enjoyment of agricultural education courses, parental and teacher support and encouragement, resources (money and facilities), and opportunities for awards and recognition did not seem to influence student SAE participation. Contrary to previous research, involvement in community and school activities did not seem to negatively influence student SAE participation. Students did not believe they needed more SAE and recordkeeping instruction.

The Cyprus Question: Continuity, Transformation And TendenciesTuzunkan, Murat 01 September 2007 (has links) (PDF)
This study has three main objectives. First, it provides a theoretical framework that challenges the mainstream approaches to allow for a new reading of the Cyprus Question. Second, it identifies continuities, transformations and tendencies within different historical periods by analyzing the positions of the various actors and the international conjecture in order to offer a correct reading of all previous settlement proposals and indicate the basis on which perceptions and policies were constructed and why the latter failed repeatedly to resolve the Cyprus issue. Continuities are those factors that created the continuum of the crisis and were concretely reflected in the successive failures of different peace talks, plans and initiatives / examining these means analyzing the hegemonic projects of the various actors involved. Examining transformations means looking specifically at how and why these hegemonic projects changed. Examining tendencies means pointing out the latest developments such as accumulated sovereignty, shared sovereignty as protectorate, Taiwan Model, return to 1960, integration through class strategy and independent TRNC and exploring the logical consequences of developments. Third, this study focuses on the European Union&rsquo / s hegemonic projects related to Cyprus &ndash / how they emerged, the relationship between these projects and the domestic and international political conjectures, their aspects of continuity and reasons for transformation and their successes and failures. This thesis argues that all the previous plans and initiatives by international and local actors, latest being the EU-initiated Annan Plan, led not only to failure, but transformed the Cyprus Question from one paradigm to another.

Looking To Development Projects In Turkey From Empowerment Approach: Case Studies In Zumrut-kastamonu And Ovacik-tunceliOzguler, Cevahir 01 December 2007 (has links) (PDF)
This study has discussed women&rsquo / s empowerment through development projects. For this aim, development thought and practices are questioned by establishing their relationship with modernization theory and (neo)liberal politics / the theories, which include women and development, are issued historically. From these theories, Women in Development (WID) Approach, Gender and Development (GAD) Approach, and Empowerment Approach are critically discussed. In the study three
points are emphasized. Firstly, the theoretical approaches have developed by articulating to each other. Secondly, the approaches have lost their transformative and political characteristics in the usage of mainstream development theoricians and institutions. It is pointed that the inclusion of women into development by the mainstream is instrumentalized for the other development goals. Thirdly, although the language of GAD and Empowerment Approaches are adopted by the mainstream, at the discursive and practical level, the dominancy of WID continues.
The development projects implemented in Turkey, in the period between 1960 and 1980 and post 1980 that are significant periods of the economic and political history of Turkey, are evaluated from gender perspective and their parallel characteristics to the discourse and practices in the world are indicated. It is seen that whereas the GAD and Empowerment Approach exist in the language of the development
projects implemented in Turkey, they do not reflect to the practices.
Within the light of these discussions, to be able to comprehend whether the development projects provide contribution to women&rsquo / s empowerment or not, two
development projects that are implemented in Turkey are analyzed. The projects are assessed from the Empowerment Approach, as a current feminist approach in the
development field, within the framework of power relations.

An Institutional Assessment Of World Bank Projects For Effective Provision Of Urban ServicesAlbayrak, Turgay 01 January 2009 (has links) (PDF)
The main aim of this thesis is to assess the institutional arrangements shaped with a perspective of &ldquo / good governance&rdquo / in provision of urban services with reference to the shift of the World Bank&rsquo / s approach to the problem of poverty after 1990s. In spite of the change in the World Bank&rsquo / s perspective, there remain significant problems related with the expected reflection of these institutional arrangements to the practice through certain process and stages of the implemented projects. Regarding this fact, thesis seeks to determine not only the reasons of these problems but also ways for solving them to attain effective provision of urban services.
In this thesis, also, as an institutional comparative assessment, some implemented service projects of the World Bank in Turkey are examined by stressing on the institutional dimension of the project objectives.
At last, thesis makes suggestions about the unsuccessful dimensions and reveals the roles of institutions in the achievement of projects by using the institutional assessment method for the institutions whose institutional capacity has been developed or the institutions created within the World Bank projects implemented in Turkey. This will be achieved by the evaluations on projects with the outputs of institutional assessment and the research on factors for the achievement of the projects.
The results obtained with this thesis study are noteworthy for the evaluation with a new perspective of the projects implemented in Turkey not only by the World Bank but also by other international institutions quite increased in number in recent years.

A Probabilistic Schedule Delay Analysis In Construction Projects By Using Fuzzy Logic Incorporated With Relative Importance Index (rii) MethodOzdemir, Mustafa 01 July 2010 (has links) (PDF)
The aim of this thesis is to propose a decision support tool for contractors before the bidding stage to quantify the probability of schedule delay in construction projects by using fuzzy logic incorporated with relative importance index (RII) method. Eighty three (83) different schedule delay factors were identified through detailed literature review and interview with experts from a leading Turkish construction company, then categorized into nine (9) groups and visualized by utilizing Ishikawa (Fish Bone) Diagrams. The relative importances of schedule delay factors were quantified by relative importance index (RII) method and the ranking of the factors and groups were demonstrated according to their importance level on schedule delay. A schedule delay assessment model was proposed by using Fuzzy Theory in order to determine a realistic time contingency by taking into account of delay factors characterized in construction projects. The assessment model was developed by using Fuzzy Logic Toolbox of the MATLAB Program Software. Proposed methodology was tested in a real case study and probability of schedule delay was evaluated by the assessment model after the required inputs were inserted to software. According to the case study results, the most contributing factors and groups (that need attention) to the probability of schedule delays were discussed. The assessment model results were found to be conceivably acceptable and adequate for the purpose of this thesis.

Looking At The Urban Transformation Project From The Gecekondu DwellersPoyraz, Ufuk 01 June 2011 (has links) (PDF)
The gecekondu settlements emerged as a grassroots solution to the housing problem of migrant population in the lack of effective state intervention. Although most of these settlements gained legal status and title deeds in the following decades, they were still considered to be problem to be solved in due process. Starting from the mid-1980s, as a result of the so-called rehabilitation plans, considerable part of the gecekondu areas underwent a rapid redevelopment process through the market mechanism. The gecekondu owners gave their land to individual small scale developers in return for some portion of flats built in the land plot. However in the 2000s this strategy has changed with the introduction of state-led urban transformation projects. Transformation processes have started to consider the large gecekondu areas rather than the individual land plots as the unit of redevelopment. This brought the market model to a halt as well. It is not any more possible for the gecekondu owners to negotiate with the developers. Instead they have to deal with municipalities. Likewise the share of the gecekondu owners from the emerging rent declined dramatically as well. Such a model meets considerable resistance from the gecekondu owners. They see this process highly unfair and many of them decline to sign the agreement documents with municipal authorities. However there are also segments of gecekondu owners who accept the offer of the public authorities. The main aim of this thesis is to analyse the urban transformation projects with regard to the attitudes of the gecekondu dwellers. The question intended to be answered by the thesis is as to why some of the owner accept the offers while the others decline. While doing this, thesis also raise some further issues beyond the distribution of emerging rents such as the destruction of local communities and their life styles.

Resource Investment Problem With Time/resource Trade-offsColak, Erdem 01 July 2011 (has links) (PDF)
In this study, we consider a resource investment problem with time/resource trade-offs in project environments. We assume each mode of an activity is characterized by its processing time and resource requirement and there is a single renewable resource. Our aim is to minimize the maximum resource usage, hence the total amount invested for the single resource.
We formulate the problem as a mixed integer linear model and find optimal solutions for small sized problem instances. We propose several lower bounding procedures to find high quality estimates on the optimal resource investment cost. We use our lower bounds to evaluate the performance of our heuristic procedures.
The results of our computational experiments have revealed the satisfactory performances of our lower bounds and heuristic procedures.

Design build project delivery in the Air Force Reserve CommandRichardson, Kathleen 01 July 2009 (has links)
Design Build is rapidly becoming one of the most commonly used project delivery methods in the construction industry. The United States Corp of Engineers (USACE) has started implementing its own version of Design Build with the introduction of Military Transformation in April 2005. Per the Department of the Army (2008) Military Transformation is a term employed by the Corps to implement the use of alternate project
delivery method as a means of achieving best value. The United States Air Force (AF)
and the Air Force Reserve Command (AFRC) are expected to establish a target of 75% of
all future Military Construction Projects (MILCONs) executed when using the Design
Build method. The use of this delivery method results in significant changes to the
relationships between the various parties associated with facility project delivery
compared to the traditional Design Bid Build method. AFRC construction project
procedures and requirements must also change.

Bayesian framework for improved R&D decisionsAnand, Farminder Singh 25 March 2010 (has links)
This thesis work describes the formulation of a Bayesian approach along with new tools to systematically reduce uncertainty in Research&Development (R&D) alternatives. During the initial stages of R&D many alternatives are considered and high uncertainty exists for all the alternatives. The ideal approach in addressing the many R&D alternatives is to find the one alternative which is stochastically dominant i.e. the alternative which is better in all possible scenarios of uncertainty. Often a stochastically dominant alternative does not exist. This leaves the R&D manager with two alternatives, either to make a selection based on user defined utility function or to gather more information in order to reduce uncertainty in the various alternatives. From the decision makers perspective the second alternative has more intrinsic value, since reduction of uncertainty will improve the confidence in the selection and further reduce the high downside risk involved with the decisions made under high uncertainty.
The motivation for this work is derived from our preliminary work on the evaluation of biorefiney alternatives, which brought into limelight the key challenges and opportunities in the evaluation of R&D alternatives. The primary challenge in the evaluation of many R&D alternatives was the presence of uncertainty in the many unit operations within each and every alternative. Additionally, limited or non-existent experimental data made it infeasible to quantify the uncertainty and lead to inability to develop an even simple systematic strategy to reduce it. Moreover, even if the uncertainty could be quantified, the traditional approaches (scenario analysis or stochastic analysis), lacked the ability to evaluate the key group of uncertainty contributors. Lastly, the traditional design of experiment approaches focus towards reduction in uncertainty in the parameter estimates of the model, whereas what is required is a design of experiment approach which focuses on the decision (selection of the key alternative). In order to tackle all the above mentioned challenges a Bayesian framework along with two new tools is proposed. The Bayesian framework consists of three main steps:
a. Quantification of uncertainty
b. Evaluation of key uncertainty contributors
c. Design of experiment strategies, focussed on decision making rather than the traditional parameter uncertainty reduction
To quantify technical uncertainty using expert knowledge, existing elicitation methods in the literature (outside chemical engineering domain) are used. To illustrate the importance of quantifying technical uncertainty, a bio-refinery case study is considered. The case study is an alternative for producing ethanol as a value added product in a Kraft mill producing pulp from softwood. To produce ethanol, a hot water pre-extraction of hemi-cellulose is considered, prior to the pulping stage. Using this case study, the methodology to quantify technical uncertainty using experts' knowledge is demonstrated.
To limit the cost of R&D investment for selection or rejection of an R&D alternative, it is essential to evaluate the key uncertainty contributors. Global sensitivity analysis (GSA) is a tool which can be used to evaluate the key uncertainties. But quite often global sensitivity analysis fails to differentiate between the uncertainties and assigns them equal global sensitivity index. To counter this failing of GSA, a new method conditional global sensitivity (c-GSA) is presented, which is able to differentiate between the uncertainties even when GSA fails to do so. To demonstrate the value of c-GSA many small examples are presented.
The third and the last key method in the Bayesian framework is the decision oriented design of experiment. Traditional 'Design of Experiment' (DOE) approaches focus on minimization of parameter error variance. In this work, a new "decision-oriented" DOE approach is proposed that takes into account how the generated data, and subsequently, the model developed based on them will be used in decision making. By doing so, the parameter variances get distributed in a manner such that its adverse impact on the targeted decision making is minimal. Results show that the new decision-oriented DOE approach significantly outperforms the standard D-optimal design approach. The new design method should be a valuable tool when experiments are conducted for the purpose of making R&D decisions.
Finally, to demonstrate the importance of the overall Bayesian framework a bio-refinery case study is considered. The case study consists of the alternative to introduce a hemi-cellulose pre-extraction stage prior to pulping in a thermo-mechanical pulp mill. Application of the Bayesian framework to address this alternative, results in significant improvement in the prediction of the true potential value of the alternative.

Communicating Knowledge in Globally Dispersed Teams : A Study of Autoliv / Kommunikation av Kunskap i Globalt Spridda Team : En Studie av AutolivLövsund, Jenny C., Spiegelberg, Thomas H. January 2002 (has links)
<p>Background: As companies are operating more and more globally, the need for increasingly coordinating and cooperating activities are becoming important. One solution to problems associated with work in globally dispersed teams can be to organize business activites, such as product development, virtually. A virtual setting for knowledge transfer is becoming a part of day-to-day activities for globally dispersed organizations such as Autoliv, the company in focus for this study. </p><p>Purpose: To explore to what extent and in what respect companies can, using virtual teams in the product development process, by codifying knowledge, improve communication and transfer of knowledge between business units within and between projects in order to improve and increase cooperation and coordination. </p><p>Method: The approach taken, has been an hermeneutic case study where we have carried out 16 in-depth interviews with a total of 17 respondents. The interviews have been carried out in face-to-face or videoconference settings with Autoliv employees from all over the world. </p><p>Results: Codification should be used as a complementary tool to the personalization strategy within knowledge intensive companies. The fact that Autoliv’s product development teams often are globally dispersed creates an even larger need for codification in order to reach efficiency in the knowledge sharing process. Positive effects from this can occur, such as help creating a common understanding, which will facilitate coordination and cooperation activities.</p>
