IMPACTS OF BIOFUELS PRODUCTION ON FOOD INDUSTRY IN THE PRAIRIE REGION OF CANADA

Zhong, Jing 22 August 2012 (has links)
On the Canadian Prairies, canola is a main source for biodiesel production and wheat is the primary feedstock for bioethanol production. To raise biofuel production requires a movement of resources and land away from food and grain crops, which would cause food to become scarcer and increase its price. This paper determines the impact of more biofuels production on the food industry. It considers the simultaneous estimation of share equations from both revenue function and distance function. Econometric results exploit the non-stationary nature of the data and the correlations among shares between primal and dual models are exploited by cointegration techniques. Johansen’s maximum likelihood estimator is applied to 1971-2007 data from Manitoba, Alberta and Saskatchewan. Morishima elasticity estimates indicate high long run substitutions among crops (wheat, feed grains and canola). A rise in the production of biofuel crops could cause food prices to increase, both for meat and bread.

Le vote par internet à distance : est-il conforme aux exigences du droit électoral québécois et canadien?

Mercorio, Philippe 01 1900 (has links)
La question posée est: le vote par internet à distance est-il conforme aux exigences du droit électoral québécois et canadien? Ce mémoire procède en trois étapes. Premièrement, nous déterminons quels sont les principes directeurs qui assurent à une élection sa légitimité. Deuxièmement, nous raffinons notre recherche en ne conservant que les principes qui demeurent pertinents dans un contexte électronique. Le vote doit répondre aux principes suivants: suffrage universel, périodicité, égalité, secret, liberté, sécurité et transparence du processus. Troisièmement, nous transposons les étapes du cycle électoral sur internet. Les problématiques identifiées relèvent davantage de facteurs politiques que techniques ou juridiques. Ainsi la cryptographie et l'introduction du vote individuel multiple, qui n'enregistre que le dernier vote effectué, serviraient la confidentialité du vote. La sécurité du processus pourrait être atteinte notamment par des mesures de protection physique des serveurs, une chaîne de contrôles continue et la diffusion du code source du logiciel du vote. L'accès à la technologie serait accru par la mise en place d'un réseau gratuit de points d'accès publics à internet et des activités de formation. Quant à l'accès aux handicapés, la conformité du logiciel de vote à des principes reconnus d'accessibilité y contribuerait. Pour l'identification, la stratégie des secrets partagés, entre électeurs et autorité électorale, permettrait de dématérialiser cette étape. En conclusion, les lois électorales ne s'opposent pas, dans leur esprit, au vote par internet à distance. Il suffirait de les actualiser dans leur forme. / To come to an answer, this thesis employed a three step approach; firstly, we determined the guiding principles which ensure an election's legitimacy. Secondly, we refined our research by retaining only the principles relevant in an electronic context. The vote must abide by the following principles: Vote for all, periodicity, equality, secrecy, freedom, safety and transparency of the process. Thirdly, we transposed the stages of the electoral cycle on the Internet. The identified problems are more political than they are legal or technical. For instance, the confidentiality of the vote can be helped with the use of cryptography, and the introduction of the multiple individual vote, which would make it possible to record only the last vote cast. The safety of the process can be reached by measures of physical protection of the servers, a continuous control mechanism and an access to the source code of the voting software. Accessibility to the technology could be increased with a network of public access points to the Internet, and with education clinics. With respect to the handicapped voters, the voting software should comply with recognised principles of accessibility. To identify the voters, shared secrecies between the voter and the electoral authorities could allow a dematerialisation of this procedure. In conclusion, the spirit of our electoral laws would allow for the introduction of an Internet voting process. / "Mémoire présenté à la Faculté des études supérieures en vue de l'obtention du grade de LL.M. en droit option droit des technologies de l'information"

IMPROVING EFFICIENCY OF ORDER PICKING IN PICKER-TO-PARTS WAREHOUSES

Khalil, Moayad 26 November 2013 (has links)
Order picking is considered one of the most time-consuming operations in picker-to-parts warehouses. Accordingly, more emphasis has been given to the task of improving the efficiency of order picking systems in general, and the required traveled distance during the order picking operation, specifically. In this thesis, we focus on two main factors that significantly affect the efficiency of order picking systems: the assignment storage policies, including the full-turnover, nearest-location and random storage policies; and the warehouse layout structure, in terms of the depth and the number of storage aisles. We investigate the combined effects of these two factors on the order picking travel distance. While previous research compares the full-turnover to the random storage policy, we compare the performance of the full-turnover policy to the nearest-location and random storage policies over various warehouse layout alternatives. For this purpose, we present a methodology for estimating order picking travel distance in a single-block, open-ended warehouse, under the assumptions of S-shape routing and discrete order policies.

Assessing Quality of Instruction, Student Learning, and Satisfaction for Student at a Distance

Chang, Ruei-Ping 16 December 2013 (has links)
The purpose of this study was to describe how assessing interactions in a distance course impact the quality of instruction, student leaning, and satisfaction with the course. This study, further describes how interactions can be enhanced with certain technologies. The population for this research was both undergraduate and graduate students of the college of Agriculture and Natural Resources in National Chung-Hsing University (NCHU), in Taiwan. There are twelve departments under the College of Agriculture and Natural Resources including eleven departments and one graduate institute. Data was collected from students at NCHU (Taiwan) by using Qualtrics (an online survey platform) through the Internet. All data of this research collected via Internet and used SPSS 20.0 to analysis data results. It is an anonymous survey that participants just receive the survey web address from email or academic platforms of each department. There is no any identification information for each participant. According to the findings, there are some relationships between transactional distance theory, technology, and online education. The results of the regression model point out that the learner to the course content interaction is a significant predictor for satisfaction toward online classes. Learner to the course content interaction and learner to the instructor interaction are significant predictors for quality toward online classes. Learner to the course technology interaction and learner to the instructor interaction are significant predictors for learning toward online classes. Learner to the course content interaction and learner to the instructor interaction are significant predictors of enhanced interactions in online classes. However, there is no interaction effect in learner to leaner interaction to enhance the satisfaction, quality, and learning. From the above data, the learner to the instructor interaction and the learner to the course content interaction are two important factors that influence learners’ satisfaction, quality, and learning of online courses. More participants involving in this research recommended increasing the reliability and the diversity of opinions. Besides, using the same instrument for diverse populations such as differences of culture, background, and majors may find more relationships in interactions and technologies in online education. Also, do more researches for enhancing the interaction between learner to learner and learner to the course technology. It is important to find more effective technologies and media for instructors to enhance learners’ satisfaction, quality, and learning of online education.

BEST PRACTICES FOR ONLINE THEOLOGICAL MINISTRY PREPARATION: A DELPHI METHOD STUDY

Cartwright, Jr., John Beck 31 March 2015 (has links)
John Beck Cartwright, Jr., Ed.D. The Southern Baptist Theological Seminary, 2014 This doctoral thesis intended to provide a clear vision of best practices in the area of online theological ministry training at the graduate level by consulting experts in the field. The research question that needed to be answered was, "What are the best practices for ministry preparation in online theological education?" Despite tremendous growth in online learning even among theological institutions, casual observations suggest that the decision to offer online programs may not always have been rooted in deep pedagogical or theological reflection. In other words, in the quest to utilize online education as a viable option for degree preparation, has serious thought been given to the uniqueness of the online learning environment and the potential impact of those differences to how ministry training is accomplished? Or has the choice been driven primarily by pragmatic considerations? A review of the literature revealed that research was needed that would establish consensus among the experts on best practices for online theological ministry training. This research would build on established practices of both online and theological education. This thesis was a mixed-methods exploratory sequential design that utilized the Delphi method in order to establish consensus among the experts on best practices for online theological ministry training. Seventeen experts were recruited that are involved in either the administrative oversight or teaching with seminary or graduate online theological ministry training degree programs. In an anonymous study, each expert answered eight open-ended questions about online theological ministry training. These answers were analyzed for emergent themes and served as the foundation for a Likert-type survey where forty-three statements were then analyzed as to their level of importance related to successfully meeting the four learning outcomes for the Master of Divinity for the Association of Theological Schools. These results were examined for consensus and another survey was given using only those items that achieved consensus. The findings were evaluated from both a consensus and non-consensus perspective. Results of the mixed method Delphi study provided thirty statements of best practices for online theological ministry preparation for which there was consensus. Statements achieving consensus were obtained in all four areas of learning outcomes for the Master of Divinity for the Association of Theological Schools: Religious heritage, cultural context, personal and spiritual formation, and capacity for ministerial and public leadership. Finally, the implications of these findings were discussed along with suggestions for further research.

The cosmological rest frame

McKay, James Hadden January 2015 (has links)
The analysis of the uniformity of a spherically averaged Hubble expansion in the Local Group frame of reference by Wiltshire, Smale, Mattsson and Watkins (2013) is extended. We carry out an investigation to constrain the frame of reference from which the spherically averaged Hubble expansion is the most uniform by applying arbitrary Lorentz boosts to the data. The proposition of a systematic boost offset between the Hubble expansion in the Local Group and CMB reference frames is verified within statistical uncertainties. This evidence further supports the claim that the Local Group is closer to the frame of reference in which Hubble expansion should be considered. We subsequently carry out a statistical analysis in search of a frame of minimum expansion variation and find consistent results with the systematic boost offset analysis. However, there is a considerable degeneracy to perform boosts in the plane of the galaxy, which may be a consequence of a lack of constraints from the Zone of Avoidance where data is absent. The COMPOSITE sample of 4,534 galaxies is used primarily, with the key results repeated with the recently released Cosmicflows-2 sample of 8,162 galaxies. The treatment of Malmquist distance bias is investigated in the context of the Cosmicflows-2 and COMPOSITE samples. We find systematic differences in the inclusion of the large SFI++ subsample into these catalogues. These differences are explored and the origin of Malmquist distance bias reviewed. We find the Cosmicflows-2 data produces results which naively suggest more variation of cosmic expansion than would be expected in any cosmological model when the methods of Wiltshire et al. are applied. We trace this discrepancy to the fact that the distribution Malmquist biases have not been corrected for in the Cosmicflows-2 survey.
