Encruzilhadas das modernizações: o projeto político do desenvolvimento humano no Brasil (2004 - 2015) / Intersections of modernizations: the political project of human development in Brazil (2004-2015)

Fabio Akira Shishito 16 August 2018 (has links)
A pesquisa examina o projeto político do desenvolvimento humano em suas formas de implementação, no Brasil. As propostas que emanam do Programa das Nações Unidas para o Desenvolvimento (PNUD), sobretudo através dos Relatórios do Desenvolvimento Humano (RDH), ganham características particulares no ambiente sociopolítico nacional. O projeto oriundo do órgão internacional se concretiza, principalmente, através dos esforços de implementação dos Objetivos de Desenvolvimento do Milênio (ODM). O objeto da pesquisa é constituído, assim, pelas representações discursivas dos diversos agentes políticos e econômicos direcionados ao cumprimento dos objetivos e metas denominados ODM. Uma das preocupações centrais da pesquisa diz respeito aos métodos e às instituições disciplinadoras da ação individual e coletiva dos diferentes sujeitos sociais e políticos atuantes em favor dos Objetivos do Milênio. Analisa-se as bases teóricas e metodológicas que dão suporte ao projeto político e examina-se as práticas organizacionais e as representações sob o prisma de uma sociologia da mudança social que interroga, centralmente, as relações de poder e dominação. / The research examines the human development political project in its forms of implementation, in Brazil. Proposals emanating from the United Nations Development Program (UNDP), particularly through the Human Development Reports (HRD), acquire particular characteristics in the national socio-political environment. The project originated from the international organization is realized mainly through the efforts to implement the Millennium Development Goals (MDGs). The research object is constituted, therefore, by the discursive representations of the diverse political and economic actors directed to the fulfillment of the objectives and goals denominated MDG. One of the central concerns of the research refers to the disciplinary methods and institutions for the individual and collective action of the different social and political actors working for the Millennium Development Goals. It analyzes the theoretical and methodological bases that support the political project and examines the organizacional practices and representations under the prism of a sociology of social change that interrogates, centrally, the relations of power and domination.

An Assessment of the EMAS Pump and its Potential for Use in Household Water Systems in Uganda

Carpenter, Jacob Daniel 01 May 2014 (has links)
Rural improved water supply coverage in Uganda has stagnated around 64% for a number of years and at this point more than 10 million rural people do not have access to an improved drinking water source. It has been recognized that progress toward improved water supply coverage and increased service levels may be gained through Government and nongovernmental organization (NGO) support of private investment in household and shared water supplies, commonly known as Self-supply. Self-supply can be promoted by introducing and building local capacity in appropriate and affordable water supply technologies such as hand-dug wells, manually drilled boreholes, low-cost pumps, and rainwater harvesting. Support can also be focused on technical support, marketing, financing, and strategic subsidies that promote and enhance user investment. The Uganda Ministry of Water and Environment has embraced Self-supply as a complementary part of its water supply strategy while government and NGO programs that support Self-supply have emerged. The EMAS Pump is a low-cost handpump appropriate for use in household water systems in the developing world. There are more than 20,000 in use in Bolivia, with many constructed through Self-supply. The EMAS Pump is constructed from simple materials costing about $US 10-30, depending largely on installation depth, and can be fabricated with simple tools in areas with no electricity. The EMAS Pump is used with low-cost groundwater sources such as hand-dug wells and manually drilled boreholes or with underground rainwater storage tanks. It can lift water from 30 m or more below ground and pump water with pressure overland or to an elevated tank. The objectives of this research were to conduct an assessment of the EMAS Pump that considers pumping rates, required energy, and associated costs, to characterize the EMAS Pump for its potential for use in household water systems in Uganda, and to make relevant recommendations. The potential of the EMAS Pump was assessed through testing its use with 2 subject participants (male and female) on wells of 5.1 m, 12.6 m, 17.0 m, 18.4 m, 21.1 m, and 28.3 m static water levels as part of a side-by-side comparative assessment with the Family Model version of the Rope Pump, a more widely known low-cost handpump that has recently been introduced and promoted in Uganda. Shallow and deep versions of each pump were tested on selected wells for 40-liter pumping trials. The status and feasibility of low-cost groundwater development and underground storage tanks were also explored in order to help characterize the potential of the EMAS Pump as an option for low-cost household water systems in Uganda. In general, it was observed that the EMAS Pump performed comparably to the Rope Pump in terms of pumping rates for shallow depths, but the Rope Pump outperformed it on deeper wells. It was determined that the EMAS Pump required more energy for pumping during nearly all trials. A study of relevant supply chains in Uganda concluded that the EMAS pump has a material cost that is less than 50% of the Rope Pump for most applications and 21% of the cost for shallow wells. It was also determined that the EMAS Pump could feasibly be produced nearly anywhere in the country. There are indications that low-cost wells and underground rainwater tanks are applicable in many parts of Uganda and could be paired with an EMAS Pump to achieve significant affordability for Self-supply household water systems. Recommendations are provided in terms of the feasibility of introducing the EMAS Pump as a part of Self-supply strategy in Uganda.

Evaluation of Hand Augered Well Technologies' Capacity to Improve Access to Water in Coastal Ng[oumlaut]be Communities in Panama

Hayman, Sarah 21 March 2014 (has links)
Amid the global efforts surrounding United Nations' Millennium Development Goal Target 7c to improve access to safe and sustainable drinking water among populations who lack this resource, it has become essential to monitor and evaluate progress. Development initiatives working to achieve improved drinking water access often introduce appropriate technologies designed to be sustainably owned and operated by populations in rural areas suffering from water related hardships. It is valuable to thoroughly examine the degree to which these technologies satisfy intended objectives and affect user experienced water access. The accurate reflection of impact and progress can be complex, as the evaluation of water supplies can be made based on a variety of indicators that range from "improved' or "unimproved" water source definitions to measurements of the capacity of a source to satisfy desirable conditions related to water quality, quantity, reliability, or user's preference. The goals of this research are to conduct a comprehensive analysis of the effects of two appropriate technologies on local water access using an assortment of methods including: water quality analysis, visual and manual inspection, user interviews, and an overall sustainability analysis. In Panama, the indigenous Ng[oumlaut]be people in the [Ntilde][oumlaut]Kribo coastal area are a group disproportionately affected by a lack of improved access to drinking water and challenges to the feasibility of piped gravity fed water systems that typically serve the rest of the country. An NGO aiming to ameliorate this situation introduced two improved groundwater supply technologies to the region: bailers and EMAS hand pumps. This study assesses the comparative performance of these systems and evaluates the respective performances of existing water sources, using the wide variety of quantitative and qualitative data obtained. The data collected in this investigation suggested that bailers and EMAS pumps yielded a mixed level of performance based on physical, chemical, and bacteriological water quality measurements in the shallow wells of the study environment. The technologies generally satisfied international guidelines and expected ranges based on chemical and physical parameters such as conductivity, TDS, and turbidity (with 57% of samples under 5 NTU). EMAS hand pumps demonstrated excellent bacteriological water quality with all samples indicating undetectable levels of E.coli, while bailers had a fair performance with 83% of samples falling into a range signifying intermediate to no associated health risk. When comparing the overall water quality performance between the two hand augered well systems and with existing sources, the results indicated that bailers and EMAS pumps performed similarly in all aspects except for bacteriological quality. Overall, analysis based on groupings of "improved" and "unimproved" sources yielded very little distinction between the two categories when considering chemical, physical, and bacteriological parameters. This highlights the added value of using alternative indicators such as WHO guidelines to assess water sources, despite the challenges associated with field water quality sampling. Interview data demonstrated that hand augered wells significantly improved household water access in the study area based on user considerations by providing a reliable water drinking water alternative with adequate quantities of water perceived to be clean. Accordingly, the improved water systems were integrated as a resilient water source into a socio-cultural context noting variable dependence on multiple water sources with categorized, appropriate related water uses set informally by Ng[oumlaut]be families. The overall sustainability analysis found EMAS hand pump and bailer technologies to be effective and appropriate; featuring low costs, few materials, and simple designs. Bailer systems were considered to be especially promising for applications in similar remote areas with high groundwater tables. However, the ultimate sustainability of both systems in the local context was found to be largely dependent on factors related to the development strategy adopted while implementing these systems in the [Ntilde][oumlaut]Kribo area.

Multi-Label Text Classification with Transfer Learning for Policy Documents : The Case of the Sustainable Development Goals

Rodríguez Medina, Samuel January 2019 (has links)
We created and analyzed a text classification dataset from freely-available web documents from the United Nation's Sustainable Development Goals. We then used it to train and compare different multi-label text classifiers with the aim of exploring the alternatives for methods that facilitate the search of information of this type of documents. We explored the effectiveness of deep learning and transfer learning in text classification by fine-tuning different pre-trained language representations — Word2Vec, GloVe, ELMo, ULMFiT and BERT. We also compared these approaches against a baseline of more traditional algorithms without using transfer learning. More specifically, we used multinomial Naive Bayes, logistic regression, k-nearest neighbors and Support Vector Machines. We then analyzed the results of our experiments quantitatively and qualitatively. The best results in terms of micro-averaged F1 scores and AUROC are obtained by BERT. However, it is also interesting that the second best classifier in terms of micro-averaged F1 scores is the Support Vector Machines, closely followed by the logistic regression classifier, which both have the advantage of being less computationally expensive than BERT. The results also show a close relation between our dataset size and the effectiveness of the classifiers.

Inclusion of the African Diaspora in Florida Nonprofit Organizations

Asana, Lydia 01 January 2018 (has links)
Social and economic challenges in one part of the world influence budgets, security, health, and well being of populations globally as was the case with the 2014 Ebola outbreak. Deficits in healthcare, education, governance, and the economy in African nations result in financial and social contributions from the diaspora residing in the United States. Many African-born immigrants to Florida came with useful knowledge and experience from their home nations that could be a valuable resource in carrying out effective development initiatives. However, accessing that knowledge is challenging. The purpose of this research was to explore the inclusion of members of the African diaspora community in Florida nonprofit development initiatives. The transnational theory of migration underpinned the following research question: What are barriers to, and opportunities for, including members of the African diaspora in Florida-based NPOs that carry out development programs in Africa? Semistructured interviews were conducted with Florida nonprofit leaders (N= 21) who have development projects in Africa. Manual and computer assisted methods using NVivo 11 were used to develop codes and themes for data analysis. Identified barriers to including African diaspora in NPOs included lack of established networks and organizational awareness as well as limited service areas, service locations, funding, and leadership roles. All respondents expressed interest in engaging with diaspora members and other nonprofit leaders via expat networks. Successful engagement with the African diaspora community could promote positive social change by improving program delivery, communication, and programmatic outcomes for a mutual impact in both African and Florida-based communities.

Comparison of Bacterial and Viral Reduction Across Different Wastewater Treatment Processes

Vagadia, Aayushi R. 01 November 2018 (has links)
Today billions of people live without access to basic sanitation facilities, and thousands die every week due to diseases caused by fecal contamination associated with improper sanitation. It has thus become crucial for decision makers to have access to relevant and sufficient data to implement appropriate solutions to these problems. The Global Water Pathogen Project http://www.waterpathogens.org/ is dedicated to providing an up-to-date source of data on pathogen reduction associated with different sanitation technologies that are important if the world is to achieve the Sustainable Development Goals (SDGs) related to health and sanitation provision. In this research, a subset of the Global Water Pathogen Project (GWPP) data is used to access the reduction of bacteria and viruses across different mechanical and natural sanitation technologies. The order of expected removal for bacteria during wastewater treatment was reported as highest for a membrane bioreactor (4.4 log10), waste stabilization pond (2.3 log10), conventional activated sludge (1.43 log10), anaerobic anoxic oxic activated sludge (1.9 log10), trickling filter (1.16 log10), and upflow anaerobic sludge blanket reactor (1.2 log10). Furthermore, the order of expected removal for viruses was reported as highest for a membrane bioreactor (3.3 log10), conventional activated sludge (1.84 log10), anaerobic anoxic oxic activated sludge (1.67 log10), waste stabilization pond (1 log10), upflow anaerobic sludge blanket reactor (0.3 log10) and trickling filter (0.29 log10). It was found that hydraulic retention time (HRT) had a statistically significant relation to the reduction of bacteria in an anaerobic, anoxic oxic treatment system. Similarly, a significant relation was found between the number of waste stabilization ponds in series and the expected reduction of bacteria. HRT was also found to be a significant factor in virus reduction in waste stabilization ponds. Additionally, it was observed that waste stabilization ponds, trickling filters, and UASB reactors could obtain a greater reduction in bacteria (5-7 log10) when combined with additional treatment (e.g., chemical disinfection or use of maturation ponds). Also, mechanized systems, such as activated sludge systems and membrane bioreactors, obtained a greater reduction (2-3 log10) of viruses when compared to a natural system. It was concluded that the selection of the best suitable technology for pathogen reduction depends on environmental, design, and operational factors as well as considering the performance of specific wastewater treatment systems individually as well as when combined with other treatment technologies that may provide added removal of microbial constituents.

An Evaluation of the Use of Composting Latrines and the Perceptions of Excrement in Ngäbe Communities in Panama

Wilbur, Patricia Anna Marie 08 May 2014 (has links)
Engineers are exploring a new paradigm in wastewater treatment; focus is shifting to the recovery and reuse of energy, water, and nutrients. Ecological sanitation (EcoSan) technologies, which allow for this recovery and reuse, are an environmentally sound option for the future of sanitation. While the technology to achieve this goal of recovery and reuse exists, a limiting factor is user attitudes and perceptions. Social sciences, especially anthropology, can and should inform engineering projects to ensure socio-cultural sustainability. Since 2003, rural indigenous Ngäbe communities in Panama have been implementing ecological sanitation projects, mainly double vault urine diverting (DVUD) latrines known as composting latrines. With the help of governmental agencies and the Peace Corps, over 200 of these latrines have been built across the province of Bocas del Toro and the ñÖ Kribu region of the Comarca Ngäbe-Buglé. To this point, little monitoring and evaluation has taken place in these communities. Interviews and observations in 23 communities throughout this coastal region revealed that 70.6% of composting latrines constructed (n = 201) were completed and 71.8 % of the completed composting latrines (n = 142) are still in use. Based on observations, 65% of the latrines in use were determined to be used properly, which translates to the proper use of 45.8% of the completed latrines. To promote composting latrine adoption, social marketing and pilot latrine projects can be employed, and to improve the percentage of properly used composting latrines, education campaigns can be deployed as follow up. Utilizing suggestions made in recent literature as guidelines for the proper application of compost, analysis showed that new training messages have not reached the communities with older composting latrines. Informal interviews in 18 communities identified compost production, the lack of mosquitoes and flies, and the lack of odor as the most frequently mentioned advantages. With respect to the disadvantages, the inability to use water for anal cleansing was the most frequently mentioned disadvantage. In three communities, informal interviews and 124 surveys were used to characterize the perceptions of Ngäbes regarding feces and their use of composted human excrement as a soil amendment in agriculture. In general, the responses reflected perceptions that show no strong barrier to the operation and maintenance of composting latrines. Utilizing the Fisher's exact test and Kruskal-Wallis test, the community, sanitation classification, gender, primary occupation, and age all showed some level of association with the perceptions expressed in the survey responses. Filo Verde was more likely to respond with perceptions accepting of composting latrine use, while San San Puente was more likely to respond with "don't know" or with perceptions objecting to composting latrine use. At times, up to 37.9% of the respondents responded with negative perceptions; thus, evaluations of perceptions prior to the implementation stage are still beneficial. One discrepancy existed between the overall majority and the composting latrine user majority; 56.5% of the 124 respondents perceived the handling of human excrement as a great health risk, whereas 59.1% of the 22 composting latrine users did not. As expected, the composting latrine users responses represent the positive perceptions of feces and their reuse, but pit latrine owners were most likely to respond with perceptions contrary to those indicative of proper composting latrine behavior. Overall, males were more likely to agree with the perceptions related to composting latrine use. Regarding primary occupations, farmers consistently replied with more favorable perceptions of feces and their use as a soil amendment, while banana company workers showed more dissidence. Additionally, older participants gave responses reflecting favorable perceptions of composting latrines more than younger participants. Finally, education and household size do not have any statistically significant associations with the perceptions reflected in the survey responses.

International Actors, Norms and Human Development

Moll, Amanda L 07 January 2008 (has links)
A number of international humanitarian organizations focus on human development and aim to improve the situation of children. In many developing countries, states have not been able to fulfill the educational or basic needs of its children. To fill this void, international actors have stepped in to help with human development. This thesis focuses on answering the question: How are norms diffused to local communities? Looking at the implementation of human development norms, this paper examines the norms-based actions that NGOs take to maximize the development potential of children. Programs aimed at increasing basic education as well as fighting child labor are addressed. When exploring the norm socialization process NGOs use to promote programs in education and child labor, it is clear that a different process is present than is suggested by existing literature. This is due to the locale where norms are implemented: local communities.

The Impact of Information and Communication Technology(ICT) on Health : A Cross-Country Study

Liu, Ping-Yu 09 July 2012 (has links)
This paper examines the impact of Information and Communication Technology (ICT) on health using the data of 61 countries between 2000 and 2009 from the World Bank. The ICT variables considered in this paper include internet, fixed phones, and mobile phones. Based on the Millennium Development Goals (MDGs) of the United Nations, we select several health variables and examine the impact of ICT on these variables. These variables include life expectancy at birth, infant mortality rate, under-five mortality rate, maternal mortality ratio, and prevalence of HIV. The estimation strategies are the pooling OLS model, the fixed effect model, and the random effect model. The empirical results suggest that ICT indeed plays a significant role in improving the health level of a country. ICT effectively decreases infant mortality rates and children mortality rates, and also increases life expectancy. This finding supports the viewpoints of United Nations (UN), World Health Organization (WHO), World Bank, and International Telecommunication Union (ITU) that ICT has great potential in improving a country¡¦s health. The finding also confirms the arguments of several literatures, including McNamara (2007) and Lucas (2008), that ICT can lead to a more effective health system. In addition, we also find that fixed phones and mobile phones, which have more powerful functions in communicating and have greater flexibility, help decrease deaths due to acute diseases or emergencies; while internet displays more profound impact on improving health with the accumulation of time. Our results suggest that adopting and promoting ICT is an effective way for developing countries and less-developed countries to enhance the level of health of people. We also expect that ICT can help these countries to meet at least part of the Millennium Development Goals.

Assessment of a Modified Double Agar Layer Method to Detect Bacteriophage for Assessing the Potential of Wastewater Reuse in Rural Bolivia

Hadley, Sakira N. 01 January 2013 (has links)
Water scarcity is a global concern that impacts many developing countries, forcing people to depend on unclean water sources for domestic, agricultural, and industrial needs. Wastewater is an alternative water source that contains nutrients needed for crop growth. Wastewater reuse for agriculture can cause public health problems because of human exposure to pathogens. Pathogen monitoring is essential to evaluate the compliance of wastewater with established World Health Organization (WHO) and U.S. Environmental Protection Agency (EPA) wastewater reuse guidelines. Indicator organisms are commonly used to detect pathogens in water and wastewater because they are quick and easy to measure, non-pathogenic, and have simple and inexpensive methods of detection. The objective of this research was to develop a modified double agar layer assay method that can be conducted in the field to quantify bacteriophage to assess the quality of wastewater for agricultural reuse. Results from the modified double agar layer assay were used to investigate the potential of somatic coliphage as an indicator organism for assessing the potential presence of enteric viruses in developing world treated wastewater, and to use the criteria of a good indicator organism to compare the potential of two commonly used indicator organisms, somatic coliphage and fecal coliforms, as an indicator of enteric viruses in wastewater. A modified EPA double agar layer method was developed and deployed in a developing world rural community to effectively quantify the concentration of somatic coliphage in a community managed wastewater treatment system composed of a Upflow Anaerobic Sludge Blanket (UASB) reactor followed by two maturation lagoons. The modified method served as a good indicator of enteric viruses in the water. Somatic coliphages were easily detected and quantified in the field setting using a modified double agar layer method. Somatic coliphage was found to be a potential indicator for enteric viruses rather than fecal coliforms because of their similarity in characteristics and resistances to wastewater treatment. The concentration of somatic coliphage was only reduced by 1.05 log units across the two series maturation lagoon system. Previous literature suggested removal would range from 2.1 to 4.6 log units. Influent wastewater (previously treated by an UASB reactor) had a concentration of 4.38 E+06 PFU/ 100 mL (standard deviation = ±3.7E+06, n = 9) and the treated effluent contained 3.90 E+05 PFU/100 mL (standard deviation = ± 4.5E+05, n = 8) of somatic coliphages. Results suggest that somatic coliphage is a good potential indicator for enteric viruses in wastewater but further research needs to be done.
