The effect of literacy on access to and utilization of agricultural information for household food security at Chirau communal lands in Zimbabwe

Gundu, Moira January 2009 (has links)
The research sought to examine the effect of literacy on access to, and utilization of agricultural information for household food security at Chirau Communal lands in Zimbabwe. The study was influenced by the diffusion of innovations approach based on interviews, observation and document study. Selected female farmers from Chirau communal lands were respondents to the self administered interviews and focus group discussions. Representatives from, Agriculture Extension and the Ministry of Agriculture were key informants. Systematic Random sampling was used to select 100 female respondents from the age of 18 to above 80 from wards 1 to 10 of Chirau Rural District in Zimbabwe. Data was analyzed into themes and coded for statistical analysis using the SPSS. The country is faced with food insecurity and the main findings of this study support the view that women play an active role in food production but their potential is limited by inadequate levels of literacy that affect the way they access and utilize resources for sustainable agriculture and household food security among other factors. This may be generalized to the situation of female farmers in Zimbabwe. Improved literacy competencies among the female farmers in Zimbabwe lends itself as one of the interventions that may assist in improving access to information and its effective utilization.. This calls decision-makers to boost literacy for women, develop available agricultural information resources and harness effort towards making them accessible. While interventions may be multi-sectored, the role of government is stressed in this report.

Reciprocal technologies : enabling the reciprocal exchange of voice in small-scale farming communities through the transformation of information and communications technologies

Tisselli, Eugenio January 2016 (has links)
This dissertation claims that the reciprocal exchange of voice—an element for constructing community and strengthening political recognition—may be fostered in small-scale farming communities by (1) the appropriation and transformation of information and communications technologies, (2) artistic intervention, and (3) cross-community research. This study contributes to participatory research methodologies, particularly those that seek to tackle the diverse challenges faced by small-scale farmers from a broad, complex perspective. The main issue identified in this dissertation is as follows: The hegemony of economic behaviors, which stands as a cornerstone of neoliberal capitalism, constitutes the latest stage of a historical process in which the voices of small-scale farmers seem to have been progressively and systematically silenced, their traditional practices largely invalidated, and their reciprocal forms of social, political, and economic organization marginalized. The purpose of this study was to explore whether an open-ended, sociotechnical methodology could be designed and applied in small-scale farming communities with the aim of strengthening their reciprocal practices while amplifying the voices of their members. The author's research addressed the question of how the role of information and communications technologies can contribute to the creation of enabling environments in which subsistence farmers may exercise their own values and make their voices heard. Another goal was to study whether the reciprocal exchange of voice could relate to the construction and dissemination of a knowledge commons and improve the resilience of small-scale farmers in the context of complex and pressing challenges such as anthropogenic climate change. Consequently, the ERV (Enabling Reciprocal Voice) Methodology was developed and applied in small-scale farming communities in order to respond to the questions of this study. The ERV Methodology sought to redefine the modes of usage of information and communications technologies in order to help communities establish a shared communicational praxis and strengthen their reciprocal relations. The ERV Methodology stands in contrast with the technological determinism found in the purely solutionist, short-term initiatives that are generally implemented in small-scale farming communities. Instead of offering rapid solutions to isolated problems, the ERV Methodology sought to consolidate the social networks of farmers through online and offline interaction. The case studies examined in this dissertation were carried out in two small-scale farming communities in Tanzania and Mexico. Following the ERV Methodology, mobile phones and the Internet were used by farmers in those communities as tools for the collaborative creation of a knowledge commons focused on local agriculture. It was found that the ERV Methodology, carried out as artistic intervention, may encourage technological appropriation, induce reciprocity, and amplify voice under certain sociotechnical conditions. These findings suggest that such a methodology might benefit farmers by becoming a significant aid to increase their resilience and their capacity to face complex challenges in the longer term. However, another conclusion was that the ERV Methodology should be applied carefully, with a strong awareness of the local context, and that greater efforts must be made in order to integrate other communities, such as local authorities and scientific researchers, into the reciprocal dynamics enabled by the methodology.

Developing Maker Economies in Post-Industrial Cities: Applying Commons Based Peer Production to Mycelium Biomaterials

Rocco, Grant R 01 October 2015 (has links)
Our current system of research and production is no longer suitable for solving the problems we face today. As climate change threatens our cities and livelihoods, the global economic system preys on the weak. A more responsive, equitable, and resilient system needs to be implemented. Our post industrial cities are both products and victims of the boom-bust economies employed for the last few centuries. While some communities have survived by converting to retail and services based economies, others have not been so fortunate and have become run-down husks of their former bustling selves. The key to revitalizing these cities is to create new industries that empower people, unlike the service economies that deride and devalue them. Peer to Peer (P2P) development models like open source software communities create platforms for people to collaborate on projects and share resources. On the scale of cities, the goal is to stimulate the growth of closed loop, local, micro-economies that are inherently more stable than traditional, centralized economic models.Commons Based Peer Production (CBPP) is a term coined by Professor Yochai Benkler at Harvard Law School. It describes a new model of socio-economic production in which the labor of large numbers of people is coordinated (usually with the aid of the Internet) mostly without traditional hierarchical organization. It is based on low thresholds for participation, freely available modular tasks, and community verification of quality (peer governance). CBPP usually only applies to intellectual output, from software to libraries of quantitative data to human-readable documents (manuals, books, encyclopedias, reviews, blogs, periodicals, and more); however, this system can be adapted for physical manufacturing. A P2P system of development for material goods must be explored through the production of a common resource. Mycelium is the “roots” of fungi. It can be grown anywhere with agricultural refuse as a substrate. It has properties that make it ideal for building insulation and it is environmentally innocuous. It is Cradle to Cradle certified, and it requires little specialized equipment to produce. As a consumer product, it has had trouble gaining traction in a notoriously stubborn market dominated by hydrocarbon based market leaders like extruded polystyrene (XPS). Mycelium products are ripe for development as a regenerative building material. The goal is to increase the R-value of the material, decrease the cost of manufacturing, and carve out a market for this extraordinary product. The purpose of applying a CBPP approach is to increase the speed of development and aid in market penetration. The strategy is to decentralize manufacturing of and experimentation with the product. This requires a robust network of production nodes. Essentially, this involves setting up franchises in select markets (like the Pioneer Valley), where there is a strong interest in local, sustainable products. The nodes would be small cooperative businesses that are licensed to produce the material as well as collect data on the manufacturing and performance of mycelium insulation. The data will then be used to improve the production process. The bulk of the thesis is in designing one such node in Greenfield, MA, located adjacent to the new John W. Olver Transit Center on Bank Row St.

Seeking the Leviathan, the General Will and the Invisible Hand in Rural Guinea, West Africa: A Science of Human Nature

Bösch, Lukas 26 August 2019 (has links)
The dissertation builds a bridge from the social-philosophical works of Hobbes, Rousseau, and Smith to current game theoretical models explaining social order to two empirical applications in a rural region of Guinea. The work focuses on the central role of natural resources for human societies and uses two empirical studies to test general hypotheses on the drivers of the sustainable exploitation and the equitable distribution of natural resources. The work strictly follows a quantitative empirical approach. After discussing the methodological foundations of statistical causal analysis in a first step, the various approaches are evaluated in a simulation study. Finally, the most successful of these approaches finds its application in the analysis of the empirical data, which was collected during field research in Guinea. In the observational study, socioeconomic data are combined with environmental data to model the influence of humans on the occurrence of wild species that are exploited for economic purposes in the study area. In the experimental study, socioeconomic data is linked to experimental data from a resource distribution game to identify factors affecting the people’s behavior when sharing a common natural resource. Both the exploitation of wild species and the sharing of a natural resource show that the social context is crucial for the understanding of human behavior, as postulated by Hobbes, Rousseau, and Smith: reputation, market integration, inequality and homogeneity of the population, as well as the salience of moral norms and property rights are essential dimensions. / Die Dissertation widmet sich der zentralen Rolle von natürlichen Ressourcen für menschliche Gesellschaften. Anhand zweier empirischer Studien werden allgemeine Hypothesen zu den Determinanten der nachhaltigen Ausbeutung und gerechten Verteilung von natürlichen Ressourcen getestet. Dabei wird in der Arbeit eine Brücke von den Werken der Sozialphilosophen Hobbes, Rousseau und Smith, über aktuelle spieltheoretische Modelle zur Erklärung sozialer Ordnung, hin zu zwei empirischen Anwendungen in einer ländlichen Region Guineas geschlagen. Die Arbeit folgt strikt einem empirischen quantitativen Ansatz. Nach der Erörterung der methodischen Grundlagen der statistischen Kausalanalyse werden die verschiedenen Ansätze im Rahmen einer Simulationsstudie evaluiert. Schließlich findet der erfolgreichste dieser Ansätze in der Auswertung der Daten, die bei der Feldforschung in Guinea erhoben wurden, Anwendung. In der Beobachtungsstudie werden sozioökonomische Daten mit ökologischen Daten verknüpft, um den Einfluss der Menschen auf das Vorkommen von wilden Arten, die zu ökonomischen Zwecken ausgebeutet werden, im Untersuchungsgebiet zu modellieren. In der Experimentalstudie werden sozioökonomische Daten mit Experimentaldaten aus einem Ressourcenverteilungsspiel verknüpft, um Faktoren zu identifizieren, welche sich auf das Verhalten von Menschen beim Teilen einer gemeinsamen natürlichen Ressource auswirken. Sowohl für die Ausbeutung der wilden Arten, wie auch für das gemeinsame Teilen einer natürlichen Ressource gilt, dass der soziale Kontext für das Verhalten der Menschen von großer Relevanz ist, wie von Hobbes, Rousseau und Smith postuliert: Reputation, Marktintegration, Ungleichheit und Homogenität der Bevölkerung sowie die Salienz moralischer Normen und Eigentumsrechte sind entscheidende Dimensionen.

Burunge Wildlife Management Area and effects on the villages around- : A case study in Babati district, Tanzania

Hernold, Henni January 2020 (has links)
This study took place in northern Tanzania in Babati district. Wildlife Management Areas (WMAs) are establishments that endorse conservation of the wildlife and the environment, development and sustainable land-use in the rural areas. The aim of the organization is to provide local communities with economic benefits and including them in the projects of wildlife and habitat conservation (Kicheleri et al., 2018). However, it is unclear if the aim of the organizations has worked that well in the field. The aim of this study is to analyze some of the local attitudes, of the villages Minjingu, Vilima Vitatu and Kakoi, towards Burunge Wildlife Management Area. This study will also analyze how the membership with WMA has changed the living conditions for the inhabitants in the three villages, by conducting semi-structured interviews on villagers, a WMA secretary and the district council officer. Results indicate that the most common perception villagers have about WMA is that the household income has decreased, and the destruction on land and crops by wildlife has increased. The villagers are unhappy about how WMA handles different situations. Due to this, the majority of the respondents from all three studied villages stated they would like to end the membership with WMA.

PubMed Commons: What Happened on the Way to the Forum? Retrospective Explanatory Case Study Research and Lessons Learned from the U.S. National Library of Medicine's Online Forum for Open Science

Farabough, Michelle Claire 12 1900 (has links)
The U.S. National Library of Medicine brought the intensifying interest in open science to national attention when it joined enthusiastic scientists to introduce and host an Amazon-like rating forum on PubMed—the world's largest database of indexed biomedical and life sciences literature. The result was PubMed Commons. In June 2013, the commenting forum was introduced for open discussion about published scientific literature as part of a three-pronged approach to improve research rigor, reproducibility, and transparency. In Feb. 2018, the forum was unexpectedly discontinued. This retrospective explanatory case study research asked the question, "What happened on the way to the forum?" Answers came from a variety of resources using multiple methodologies for data collection and analysis. Historical data from PubMed Commons' 7,629 comments and 1,551 commenters; key informant interviews with PubMed Commons editors; and a systematized search for published articles, gray literature; and social media content about PubMed Commons were analyzed using computer-mediated discourse analysis and a social network analysis. Results from the quantitative content analysis described a forum with little participation, and the qualitative content analysis demonstrated that active forum members were focused primarily on providing links to other information resources and discussing aspects of post-publication peer review. The social network analysis revealed a disconnected network, which was supported by a sociogram showing a community of independents with only seven small clusters. Findings pointed to 11 factors that affected the forum's adoption and use. Rogers' diffusion of innovation theory scaffolds a forum innovation agility model developed from this work to offer a better understanding of organizational processes and to aid organizations interested in introducing and managing a similar forum. PubMed Commons was a missed opportunity. No comparable alternative is available to promote open science and serve as a tool for the expected paradigm shift in the way we do scholarly communication in science.

Grassroots niches transforming cities toward post-growth futures : A case study of the collaborative economy in Gothenburg, Sweden

Enarsson, David January 2019 (has links)
Cities drive some of the most urgent sustainability challenges that societies face today, including inequality, resource consumption and climate change. Meanwhile, economic growth is increasingly being viewed as a challenge for sustainable development, generating a call for post-growth transformation. In recent years, the notion of a sharing economy has spread to cities across the globe and has been adopted as a solution for addressing multiple urban sustainability challenges. The sharing economy is often associated with multinational corporations such as Airbnb and Uber, however, there is a parallel movement of emerging social practices. This study investigates the case of the multi-actor sharing economy in Gothenburg, Sweden, in order to assess the capacity of an emerging grassroots movement to contribute to economic transformation towards a post-growth model. The findings demonstrate how the grassroots movement show potential for radical change as they adopt and replicate goals and visions aligning with post-growth transformations. Further, the results show how the movement is reconfiguring urban governance relations through i) transformative leaders and ii) intermediary organizations enabling cross-sectorial actor relations to emerge. However, the findings also point to emerging risks of disempowerment and limited capacity of grassroots which induce three policy suggestions to strengthen the transformative capacity of the movement. These are to i) organize multi-actor exercises that foster collective visions, ii) support the development of co-operative business models for grassroots, and iii) establish a Community Support Centre. The study concludes that Gothenburg is an example of a type of sharing economy with potential for post-growth transformation.

Opting Out of Opting In: Switching Our Profile Workflow to Include Every University Faculty Member

Johnson, Kyle A., Sergiadis, Ashley 09 November 2022 (has links)
Starting this semester, Charles C. Sherrod Library at East Tennessee State University (ETSU) began shifting our SelectedWorks service model from an opt-in (we create profiles for faculty who send us their CV) process to a quicker and easier opt-out (we create profiles for all faculty) model. Our lightning talk will provide an overview of this opt-out model and how we laid the groundwork for its success. We started by engendering support amongst the Deans, Faculty Senate, and University Research Council, detailing the benefits of a university-wide profile service and assuaging any fears or concerns that an opt-out model might generate regarding utility and privacy. We also undertook a substantial harvesting project as part of this project using Digital Common's PubMed and Scopus integration to harvest thousands of ETSU-affiliated records into our repository. We create these "instant profiles" by aggregating publicly assessable information (such as contact information, education, etc.) from available sources such as university departmental pages, LinkedIn, ResearchGate, etc. to complete their "About" information without needing a copy of their CV. We then import all available works into the profile from the aforementioned harvesting project. Once completed, we email the faculty member in question and give them two weeks to accept or decline their profile before going "live." This will greatly expand the reach of our department's service and further integrate our portion of the library into the academic community of the university.

Designing International Agreements on Global Governance : Analysis of the Applicability of Ostrom’s and Stern’s Principles on the BBNJ Agreement

Nyzell, Ellinor January 2023 (has links)
Areas beyond national jurisdiction or the high seas are vital areas for biodiversity and marine resources in our oceans, yet the protection and conservation of this global resource is insufficient due to absence of international agreement concerning the matter. Therefore, the new Biodiversity Beyond National Jurisdiction (BBNJ) agreement was recently agreed upon, with the objective of ensuring protection for these resources.This study endeavours to assess the applicability of Ostrom's and Stern'sprinciples, as the theoretical frameworks for sustainable governance of global commons, on the BBNJ agreement. By employing deductive reasoning, this study compares and contrasts the principles proposed by Ostrom and Stern, using them as lenses to examine the agreement. As a case study, this research investigates the utilization of international agreements as integral components of international law for the governance of shared resources. Conducted as a qualitative desk study, the analysis involved scrutinizing the BBNJ agreement to identify keywords and themes associated with eachprinciple. The study’s findings reveal that Ostrom's and Stern's principles exhibit varying degrees of applicability. Despite sharing certain similarities, they embody distinct foundational approaches, with Stern's principles demonstrating better applicability to the governance of global commons. The study suggests that the BBNJ agreement holds the potential to govern the global commons in a sustainable manner.
