The Intergenerational Transmission and "Moralization" of Appearance and Achievement Values and Their Influence on Children's Contingencies of Self-Worth

Quinlan, Nicole Polanichka 21 February 2008 (has links)
<p>Children's internalization of parental values is differentially influenced by discipline and parent-child relationship quality. Beyond simply affecting values, parents can influence the development of underlying belief structures children use to make sense of behaviors and attributes. Parental values might lead children to experience domains as differentially important and then use this structure when building and judging the content of their self-concept. The intergenerational transmission of values may therefore also differentially influence appraisals of the self. Crocker and colleagues (e.g. Crocker, Sommers, & Luhtanen, 2002) present a model of self-esteem that emphasizes "contingencies of self-worth", which are domains on which individuals stake self-esteem. Although the existence of contingencies of self-worth (CSW) has been supported, their origin has not been addressed. This dissertation is a preliminary investigation into the origins of CSW. It is proposed that early adolescents' CSW will reflect parents' values in domains that carry a 'moral' weight due to parental socialization. The domains of physical appearance and academic achievements were of particular interest. Participants were 127 early adolescents (51% female) and their parents (102 mothers, 62 fathers) recruited from three populations in an effort to sample individuals for whom appearance and academics are differentially salient. Youth and parents each completed questionnaires addressing self-concept/self-esteem, CSW, parenting style, parent-child relationship, and domain-specific beliefs and behaviors. Results indicated that more negative ratings of transgressions in traditionally moral domains (kindness and honesty) as well as the non-traditional domain of academics were associated with higher ratings for these domains on the CSW. Parental discipline moderated the association between parents' and adolescents' ratings of transgressions in kindness, honesty, and academics, and parenting style and parent-child relationship quality moderated the association between parents' domain values and adolescents' domain ratings on the CSW. This suggests that the internalization of moral standards influences developing self-structure and that a domain that is not traditionally considered 'moral' can be raised to a 'moral' level. The results also indicate that parental socialization influences the importance adolescents' place on given domains when evaluating self worth and developmental theories regarding socialization of traditional values can also be used to understand the transmission of non-traditional values.</p> / Dissertation

A Proposed Rule For The Interconnection Of Distributed Generation And Its Economic Justification

Gezer, Dogan 01 December 2009 (has links) (PDF)
Distributed generation (DG) is electricity generation by small generating units, which are interconnected at distribution level with capacity less than 50 MW. Environmental concerns and the idea of using cheap and domestic renewable resources increased the popularity of DG following the developments in equipment technology. In Turkey, interconnection of DG is realized through the distribution busbars of 154/36 kV substation. The interconnection of DG at 36 kV feeders is not allowed by distribution system authority. This thesis proposes an interconnection rule which includes technical analyses to be conducted before the permission of interconnection of DG at 36 kV feeders. Moreover, the protection functions and operational requirements needed for the proper and safe operation of distribution system in presence of DG are introduced. A sample distribution system with relevant parameters is used for the simulation studies in Digsilent software. In order to determine the operational reserve requirement against the variations in wind generation, a statistical method including Weibull distribution, standard deviation and monthly average wind speeds is used. Convenience of hydropower plants&rsquo / response for being backup generation against the fluctuations in wind generation is analyzed by a mid-term dynamic model of the power system. A secondary control mechanism for the integration of wind power is suggested. Finally, an economic comparison between the interconnection alternatives of hydropower and photovoltaic power plants at the distribution busbar of the 154/36 kV substation and the 36 kV feeder is done by present worth analysis using the up to date power plant costs and incentives.

Reliability Cost Model Design and Worth Analysis for Distribution System Planning

Yang, Chin-Der 29 May 2002 (has links)
Reliability worth analysis is an important tool for distribution systems planning and operations. The interruption cost model used in the analysis directly affects the accuracy of the reliability worth evaluation. In this dissertation, the reliability worth analysis was dealt with two interruption cost models including an average or aggregated model (AAM), and a probabilistic distribution model (PDM) in two phases. In the first phase, the dissertation presents a reliability cost model based AAM for distribution system planning. The reliability cost model has been derived as a linear function of line flows for evaluating the outages. The objective is to minimize the total cost including the outage cost, feeder resistive loss, and fixed investment cost. The Evolutionary Programming (EP) was used to solve the very complicated mixed-integer, highly non-linear, and non-differential problem. A real distribution network was modeled as the sample system for tests. There is also a higher opportunity to obtain the global optimum during the EP process. In the second phase, the interruption cost model PDM was proposed by using the radial basis function (RBF) neural network with orthogonal least-squares (OLS) learning method. The residential and industrial interruption costs in PDM were integrated by the proposed neural network technique. A Monte-Carlo time sequential simulation technique was adopted for worth assessment. The technique is tested by evaluating the reliability worth of a Taipower system for the installation of disconnected switches, lateral fuses, transformers and alternative supplies. The results show that the two cost models result in very different interruption costs, and PDM may be more realistic in modeling the system.

Mobile Learning and Self-Worth : The Case of Syrian Refugees from a Kantian Perspective

Alshoufani, Rama January 2018 (has links)
As the war in Syria is about to enter its seventh year, Syrians continue to head towards Europe to seek safety and protection. This challenges European countries to provide urgent relief and services including education for a high number of Syrian refugees every year. However, the journey of Syrian refugees does not end with their arrival to safety. The refugee experience presents many difficulties including issues of wellbeing and self-worth. This qualitative comparative study examines the different platforms and solutions Mobile Learning could offer to refugees. In addition to that, it also discusses the possibility of leveraging Mobile Learning as a mean for Syrian refugees in Europe to achieve a sense of self-worth from the Kantian perspective of agency. The study starts with a comprehensive overview of the meaning of the term ‘refugee’ and the refugee experience, then it moves on to identify Mobile Learning and its impact and relationship to the recent refugee crisis. Then, the study introduces the Kantian philosopher Christine Korsgaard and her idea of agency, action, identity and value. The literature review after that discusses Korsgaard’s philosophy and links it to refugees and Mobile Learning. After viewing the research methods and methodology, the study comparatively analyses and discusses findings drawn from semi-structured interviews of 10 participants pertaining to the use of Mobile Learning platforms for higher education and language learning. The implications of these findings are that Syrian refugees in Europe have access to Mobile Learning platforms that vary in use and quality. However, when these platforms are used successfully, they do have the potential to support refugees’ sense of self-worth. The study then ends with a conclusion and suggestions for future research.

No. of bitstreams: 1 Morgana1.pdf: 314849 bytes, checksum: 0e76a30ac473b73d89fbc3ab4732ce74 (MD5) Previous issue date: 2011-07-29 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / In recent decades, Civil Society Organizations (CSOs) have played a central role on the stage of public sphere. The expansion of the interest in CSOs has been accompanied by criticisms against their performance, questioning mainly their representativeness, impact, accountability, transparency, in short, their own legitimacy. In this scenario, the present work parts of the following research question: what are the dominant justifications that support the role and the existence of CSOs, providing them with legitimacy, according to representative actors of the field? To answer this question, the theoretical methodological path is structured in Five chapters, besides the introduction and conclusion. In Chapter 1 we enter into the theoretical debate about legitimacy of CSOs, which is composed mostly by studies that focus on technical issues and seek to identify the presence of factors that confer legitimacy for CSOs. This dissertation, however, addresses the phenomenon as a social construct that depends on the CSOs and on the external forces with which they interact. To better understand how legitimacy is constructed, in Chapter 2 we mobilize the Economies of Worth theory, formulated by Boltanski and Thévenot (1991), for which the construction of agreements in society takes place through processes of justifications that legitimize them, based on the common worlds, resulting in the construction of an analytical framework to examine the logics behind the legitimacy of CSOs. In Chapter 3, by analyzing the trajectory of the field in Brazil, we seek to identify the common worlds that underlie the construction of legitimacy of CSOs, which allowed the formulation of research hypotheses. The methodology of the work is described in Chapter 4 and the method used is the content analysis of interviews held with 46 managers of CSOs performing in the capitals of southern Brazil. As results, explored in Chapter 5, the presence of several common worlds was observed in the justifications of the actors. Through frequency analysis, it is verified that 42.01% of the relevant words belong to the industrial world; 29.11% to civic world; 10.10% to domestic world; 8.57% to world of projects; 7.58% to marked world; 1.42% to world of fame and 1.12% to world of inspiration. It was observed that there are conflicts between the logics that cohabit the field, but these disputes are not very explicit, since there is a process of adaptation and homogenization of the practices of CSOs to meet the tests which they are subjected to (mostly belonging to the industrial world). The common worlds present in the field also build bridges between themselves and some of these commitments generate wider repercussions, such as the terms social responsibility, solidarity economy and sustainable development. Finally, we realize that there are logics that isolate the existence of others, with a large predominance of the industrial logic, overshadowing logics that have been representative for the field, as the inspired and domestic ones. The results corroborate the conclusion that the dimensions of legitimacy that predominate in CSOs nowadays are the pragmatic and the moral dimensions, which are based on the response to the demands of stakeholders and encourage the adaptation of CSOs to externally set standards. In this sense, to strengthen democracy, it is recommended that CSOs focus on the cognitive dimension of legitimacy, influencing the external environment in the construction of meanings for their existence and fostering the conceiving of their own conventions for legitimacy / Nas últimas décadas, as Organizações da Sociedade Civil (OSCs) têm assumido um papel central no palco da esfera pública. A ampliação do interesse pelas OSCs veio acompanhada por críticas à sua atuação, tendo destaque os construída, recorremos no Capítulo 2 à Teoria das Grandezas, formulada por Boltanski e Thévenot (1991), segundo a qual a construção de acordos se dá por meio de processos de justificações que os legitimam, baseados nos mundos comuns, resultando na construção de um quadro de análise para examinar as lógicas que embasam a legitimidade das OSCs. Buscou-se, no Capítulo 3, a partir da análise da trajetória do campo no Brasil, identificar os mundos comuns que fundamentaram a construção da legitimidade das OSCs, o que permitiu formular as hipóteses de pesquisa. A metodologia do trabalho é descrita no Capítulo 4 e a análise de conteúdo de entrevistas com gestores de 46 OSCs que atuam nas capitais do Sul do Brasil foi utilizada como método. Como resultados, explorados no Capítulo 5, verificou-se a presença de diversos mundos comuns nas justificações dos atores. Na análise frequencial aufere-se que 42,01% das palavras significativas pertencem ao mundo industrial; 29,11% ao cívico; 10,18% ao doméstico; 8,57% ao de projetos; 7,58% ao mercantil; 1,43% ao da fama e 1,12% ao da inspiração. Observou-se que existem conflitos entre as lógicas que coabitam o campo, porém estas disputas não são muito explícitas, visto que ocorre um processo de adequação e homogeneização das práticas das OSCs para corresponderem aos testes aos quais são submetidas (pertencentes na sua maioria ao mundo industrial). Os mundos comuns presentes no campo também constroém pontes entre si e alguns desses compromissos geram repercussões mais amplas, como é o caso dos termos responsabilidade social, economia solidária e desenvolvimento sustentável. Finalmente, percebe-se que existem lógicas que isolam a existência de outras, com ampla predominância da lógica industrial, ofuscando lógicas que já foram representativas para o campo, como a inspirada e a doméstica. Os resultados corroboram para concluir que as dimensões da legitimidade que predominam nas OSCs na atualidade são a pragmática e a moral, as quais têm por base a resposta às demandas dos stakeholders e estimulam a adaptação das OSCs a padrões externamente estabelecidos. Nesse sentido, para fortalecer a democracia, recomenda-se que as OSCs focalizem a dimensão cognitiva da legitimidade, influenciando o ambiente externo na construção dos sentidos para a sua existência e promovendo a concepção de suas próprias convenções de legitimidadequestionamentos sobre representatividade, impacto, accountability, transparência, em suma, sobre a sua própria legitimidade. Nesse cenário, esse trabalho parte da seguinte pergunta de pesquisa: quais são as justificações dominantes que embasam a atuação e a existência das OSCs, e, portanto, lhes conferem legitimidade, de acordo com os atores representativos do campo? Para responder esta questão, o caminho teórico metodológico se estrutura em cinco capítulos, além da introdução e conclusão. No Capítulo 1 adentramos no debate teórico sobre legitimidade, o qual é composto, na sua maioria, por estudos que focalizam aspectos técnicos e buscam identificar a presença de fatores que conferem legitimidade às OSCs. Esta dissertação, no entanto, aborda o fenômeno como um construto social que depende das OSCs e das forças externas com as quais interagem. Para compreender melhor como a legitimidade é

Program "note your money worth": an assessment of its effects on the collection of vat in retail trade cearense / Programa âsua nota vale dinheiroâ: uma avaliaÃÃo dos seus efeitos sobre a arrecadaÃÃo de ICMS no comÃrcio varejista cearense

Nathalia Fontenele Silva 08 February 2012 (has links)
nÃo hà / This paper analyzes the impact of the Program âYour Receipt is Worth Moneyâ created by the Department of Finance of the state of CearÃ, to stimulate people to demand receipts when purchasing goods from stores. Thus, the Program tends to increase the collecting of VAT due to the issuing of invoices and, at the same time, lower tax evasion, since at SEFAZ/CE, part of the collection returns to the tax payer registered in the program. The analysis of the effects of the Program âYour Receipt is Worth Moneyâ SEFAZ/CE, on the collection of the State of CearÃ, was performed using linear regression models, and, for this, we used the collection of VAT retail trade, the indices of the volume of retail sales and industrial production. In all models, these ratios were statistically significant and positively affect the collection of VAT retail. In terms of evaluation, it was observed that, in some models, the Program âYour Receipt is Worth Moneyâ has a positive effect on the collection and in others the effect is null-statistically equal to zero. / Este trabalho objetiva analisar o impacto do Programa âSua Nota Vale Dinheiroâ criado pela Secretaria da Fazenda do Estado do CearÃ, visando estimular a populaÃÃo a exigir o documento fiscal ao adquirir mercadorias junto ao comÃrcio varejista. Sendo assim, o Programa tende a aumentar a arrecadaÃÃo de ICMS por conta da emissÃo de notas fiscais e, ao mesmo tempo, por menor sonegaÃÃo fiscal, uma vez que a SEFAZ/CE devolve parte da arrecadaÃÃo ao contribuinte cadastrado no Programa. A anÃlise do efeito do Programa âSua Nota Vale Dinheiroâ da SEFAZ/CE sobre a arrecadaÃÃo do Estado do Ceara, foi realizada por meio de modelo de regressÃo linear e, para isto, foram utilizadas a arrecadaÃÃo do ICMS do comÃrcio varejista, os Ãndices do volume de vendas do comÃrcio varejista e da produÃÃo industrial. De acordo com os resultados, todos estes Ãndices foram estatisticamente significantes e afetam positivamente a arrecadaÃÃo de ICMS do varejo. Em termos de avaliaÃÃo, observou-se que o Programa âSua Nota Vale Dinheiroâ possui efeito positivo sobre a arrecadaÃÃo.

Agresivita, hostilita a její vliv na interpretaci sociálních situací / Aggression, hostility and its influence on interpretation of social situations

Kunšta, Cyril January 2016 (has links)
Goal of a master thesis was to explore connection between aggression and interpretation of ambiguous social situations. In theoretical part of thesis author described theories of aggression, he was dealing with sources of aggression and also with criminal aggression with an overlap to typology of violent offenders. Author also described the problematic of ambiguous social situations and phenomena connected with it. In empirical part of thesis the main goal was to explore interconnection between aggression and interpretation of ambiguous social situations; and to compare group of inmates convicted for committing a violent crimes (n=30) with comparison group (n=30) in external aggression, understanding of ambiguous social situations and perceived social worth. For the purpose of exploring ambiguous social situations, methods DSS and SIP-AEQ were used. For exploring of external aggression were used Rosenzweig's PFT and for perceived social worth the SWS method. Two of four hypotheses were confirmed.

What Makes Water Policy Sustainable? An Analysis of Water Policy in US Cities

David, Rebecca Brady 25 February 2017 (has links)
This dissertation works to create a clearer understanding of sustainability in water policy. Current water policy in four US cities was compared to a matrix of recommended sustainability themes that have been presented in the literature to determine the extent of which these themes have been implemented into water policy. To best analyze policy for sustainability it is necessary to look at the policy of cities that are considered sustainable. This was determined by a city’s inclusion in “Most Sustainable US Cities” lists. The two cities that best represented sustainability were Austin, TX and San Francisco, CA. The research also included cities that are not considered leaders in sustainability but are similar in demographics, population, and state; these two cities are Fort Worth, TX and San Jose, CA. Finally, the same matrix was applied to the state policy to establish how state policy influences city sustainability. The results of this study add to the current knowledge in this field as it contributes a current analysis of sustainable water policy. The final findings compile the themes into a sustainability pyramid framework of common, uncommon, and rare sustainability. It appears that the ‘sustainable’ cities have included more uncommon and rare themes than the traditional cities, while common themes are implemented across the board. Common themes are those that are traditionally associated with sustainability – themes like conservation, reuse, and reducing pollutant impact on water sources. In order increase sustainability, cities should apply more of the themes from the top of the pyramid.

Multi-Criteria Evaluation in Support of the Decision-Making Process in Highway Construction Projects

jia, jianmin 31 March 2017 (has links)
The decision-making process in highway construction projects identifies and selects the optimal alternative based on the user requirements and evaluation criteria. The current practice of the decision-making process does not consider all construction impacts in an integrated decision-making process. This dissertation developed a multi-criteria evaluation framework to support the decision-making process in highway construction projects. In addition to the construction cost and mobility impacts, reliability, safety, and emission impacts are assessed at different evaluation levels and used as inputs to the decision-making process. Two levels of analysis, referred to as the planning level and operation level, are proposed in this research to provide input to a Multi-Criteria Decision-Making (MCDM) process that considers user prioritization of the assessed criteria. The planning level analysis provides faster and less detailed assessments of the inputs to the MCDM utilizing analytical tools, mainly in a spreadsheet format. The second level of analysis produces more detailed inputs to the MCDM and utilizes a combination of mesoscopic simulation-based dynamic traffic assignment tool, and microscopic simulation tool, combined with other utilities. The outputs generated from the two levels of analysis are used as inputs to a decision-making process based on present worth analysis and the Fuzzy TOPSIS (Technique for Order Preference by Similarity to Ideal Situation) MCDM method and the results are compared.
