An Exploration of Food Security and Agriculture Challenges for Female Farmers in Rubkona County, South Sudan

Jieknyal Jr, Bijiek Gatwech 10 March 2016 (has links)
The purpose of this study was to explore food security and agricultural challenges to examine the feasibility of using extension services as food security challenges intervention. The study used extension services, microfinance, farm cooperatives, and educational strategy to apply the Theory of Planned Behavior (TPB) to investigate culturally specific attitudes, subjective norms and perceived behavioral constructs in relationship to female economic development through agricultural production. The use of semi-structured interviews in a qualitative research design was found useful in exploring the informants' experiences in challenges to food security and agricultural productivity not only in South Sudan, but also in Sub-Saharan Africa. In-depth one on one semi-structured interviews were conducted with farmers and international agriculture researchers. / Ph. D.

Mécanismes de l'extension continentale au Mésozoïque en Asie de l'Est / Mechanisms of Mesozoic continental extension in East Asia

Charles, Nicolas 01 December 2010 (has links)
La lithosphère continentale peut s’étirer selon trois modes (rift large, rift étroit et Core Complex). En Asie de l’Est, une extension continentale a eu lieu de la fin du Mésozoïque au Cénozoïque et ne semble correspondre à aucun des trois modes actuellement définis. Cette période est caractérisée par un amincissement lithosphérique exceptionnel (>100 km), la présence de MCC, de bassins sédimentaires et une importante activité magmatique. Basé sur une approche multi-échelles, ce travail vise à mieux comprendre les mécanismes à l’origine de cette déformation lithosphérique (jamais abordés) ainsi que du moteur de l’extension (encore vivement discuté). Pluridisciplinaire, cette étude apporte de nouvelles contraintes à partir de l’analyse de la déformation finie (ductile ou fragile), du magnétisme des roches (ASM, paléomagnétisme), de la géochronologie (U/Pb sur zircon et 40Ar/39Ar sur monograins) et de la gravimétrie. Différents objets reconnus, révélant des quantités d’extension différentes (MCC vs. pluton cisaillé), montrent que la croûte continentale se déforme de manière très localisée, par la mise en place de larges dômes extensifs séparant des domaines de « radeaux » ou « boudins » présentant une déformation faible à nulle. Par comparaison des données crustales et mantelliques (tomographie sismique, géochimie) disponibles, cette étude met en évidence que l’amincissement lithosphérique reconnu pour le Mésozoïque est principalement lié à un important flux thermique du manteau, l’extension n’ayant qu’un rôle limité dans cet amincissement (<20%). En outre, eu égard au gradient géothermique exceptionnellement élevé de la région, à la fin du Mésozoïque, il semble très probable que des MCC puissent s’être développés sans épaississement préalable de la croûte. L’analyse comparée des directions d’étirement dans la croûte et dans le manteau met en évidence le rôle majeur de la subduction des panneaux plongeants le long de la marge est-asiatique. Un modèle géodynamique a été proposé montrant le rôle du retrait successif des panneaux plongeants couplé à un phénomène d’érosion thermique de la lithosphère. / Continental lithosphere can be stretched according to three modes (wide rift, narrow rift, Core Complex). In East Asia, a continental extension occurred during the Late Mesozoic to Cenozoic times and seems to do not correspond to any of three modes currently defined. This period is characterised by an exceptional lithospheric thinning (> 100 km) with the presence of MCC, sedimentary basins and a huge magmatic activity. Based on a multi-scale approach, this work aims to better understand the mechanisms of this lithospheric deformation (never addressed) and the engine of the extension (yet highly debated). This study provides new multidisciplinary constraints from the analysis of finite strain (ductile or brittle), rock magnetism (AMS, palaeomagnetism), geochronology (U/Pb on zircon and 40Ar/39Ar on single crystals) and gravity. Different objects have been recognised, revealing different amounts of extension (MCC vs. sheared pluton), and show that the continental crust is locally highly deformed, with emplacements of large MCCs between "rafts" or "boudins" domains which are weakly strained to unstrained. By comparison of available crustal and mantle data (seismic tomography, geochemistry), this study shows that the lithospheric thinning recognised for the Mesozoic is mainly related to a major mantle heat flux, the extension plays a limited role in this thinning (<20%). In addition, given the exceptional high geothermal gradient in the region at the end of the Mesozoic, it seems very likely that MCC may have developed without pre-thickened crust. Comparative analysis of stretching directions within the crust and mantle highlights that the subduction of the (palaeo) Pacific plate along the East Asian margin may play an initial and major role during Late Mesozoic extensional event. A geodynamic model has been proposed to show the role of the successive retreat of subducting slabs coupled to a thermal erosion of the lithosphere.

The Relation ship between Brand Image Perception and Brand Extension Evaluation: Package of Aquatic Products from Taiwan Water Corporation as Example

Chen, Yu-Fen 10 September 2007 (has links)
Brand contraction and Marketing constitute a new challenge in the 21st century¡¦s business development. The Smile Curve Theory provided by the founder of Acer Group, Mr. Stan Shih Z.R, who once stressed that value added manufacturing being low, the future development in Taiwan should focus on research/development and brand marketing. Due to the advancements in science technology and the keen competition among enterprises, many similar products can be found in the market. In general, branding is the motive that encourages producers to create unique products while stimulating customers to pay higher prices for what they want. Brand is an important asset to the enterprise; it not only brings profits under excellent quality control but also offers a convenient identity and enhances a company¡¦s growth. The well-known strategy of brand extension helps to reduce risks while promoting a new product in the market. However, the cost of promoting a new product into the market is higher than the cost occurred in the strategy of brand extension. For instance, the cost of promoting a new product into the market is about 50-100 million US Dollars in the American market (Brown, 1985). As a result, the advantage of applying the brand extension strategy lies in the promoting of new products and increasing the chances for success. The study aims at understanding the evaluation of brand image perception and brand extension from the viewpoint of consumers, and the study object was the package of aquatic products from Taiwan Water Corporation. The brand image perception and its image after extension constitute the independent variable. Consumers¡¦ high or low evaluation of brand image perception and the related extension were analyzed and examined to determine whether there was any significant correlation after extension. Furthermore, comparison of brand image was made between the new mineral water of Taiwan Water Corporation and others from the leading companies. The high or low brand image was sorted out in sequence and its relation ship with the brand extension evaluation was compared. Questionnaires were sent to 386 interviewees and the statistics were examined, the conclusions were drawn. Results: 1. There¡¦s significant correlation between the original brand and brand image perception after extension; if the similarity of brand extension is high, the correlation of the original brand image perception is higher than for products which have low similarity. 2. Between the original brand image perception and brand extension evaluation, the high brand image perception achieved higher brand extension evaluation than did the low brand image perception. The evaluation of brand extension with high similarity is also higher than that of brand extension with low similarity. 3. There¡¦s no interactive effect in ownership between the brand image perception and brand extension evaluation. The owner of the original brand gives a higher evaluation to brand extension with high similarity, than do non-owners. There¡¦s no significant variation between owner and non-owner to brand extension with low similarity. 4. If the similarity of brand extension is high, consumers often focus on the transferred perception of the functional image of the IT commodity. The value, function and reliability will be appreciated after brand extension. The brand extension with low similarity should emphasize the functional image and the transferred perception of the symbolized image from consumers. The fashionable image, personal style and outstanding reputation should also be formed so that a better evaluation of brand extension with low similarity can be made afterwards. Due to customers continuing to value the original brand image after brand extension of cross-classification, enterprises should treasure the influence of the original brand image and the compatible category on brand extension, as well as the variation resulting from different perceptions.

Perceptions of Texas County Extension Agents on Volunteers Who Assist With Planning and Implementation of Extension Educational Programs

Matthies, Allen Z. 2009 December 1900 (has links)
The objective of the study was to determine and evaluate county extension agents' perceptions on volunteer management competencies related to their county program. General perceptions related to volunteer management were also assessed. The research was conducted on Texas county extension agents working in the fields of agriculture and natural resources and family and consumer sciences. The purpose of this study was to make inferences concerning volunteer management based on self assessment data gained from study participants. The secondary purpose was to identify concerns and provide solutions for the Texas AgriLife Extension Service to enhance this organization. Five research questions were examined by the researcher: 1) What are the demographics of county extension agents working for the Texas AgriLife Extension Service, 2) What are the county characteristics of extension volunteers and volunteer programs in Texas, 3) What are the differences in volunteer management based on location factors such as population size and staff size, 4) Is the ISOTURE model for volunteer management utilized by county extension agents working for the Texas AgriLife Extension Service, and 5) How do county extension agents perceive their volunteer programs are viewed by the clientele they serve? The population of county extension agents was 451 at the time of data collection. Two hundred seventeen (217) responses were collected. The instrument for this study was in electronic format and was divided into three sections; general volunteerism, specified volunteerism as it relates to "Your Volunteer Group," and demographic data. The participant was asked to select a specified volunteer group which had eight predefined groups and one blank for "Other." The results of this study identified seven significant findings with seven recommendations for Texas AgriLife Extension Service regarding professional development, volunteer utilization, and volunteer structure. Conclusions reached from this research show county extension agents utilize the volunteer management model adopted by the Texas AgriLife Extension Service. Furthermore, differences in environment such as population, staffing pattern, and volunteer utilization have influence on how volunteers are utilized in different counties. Finally, the researcher identified seven areas of further research.
