Testing the Waters: The Social Contexts of Homeowner Flood Mitigation

Olivier, Maggie L. 16 May 2008 (has links)
South Louisiana regularly experiences effects from flooding. This study looks at what homeowners are doing to reduce their losses from floods through the practices of flood mitigation. I developed four hypotheses to predict homeowners' mitigation behavior. (1) Homeowners with a history of flooding are likely to mitigate more than those without previous flooding. (2) High-disposable-income homeowners are more likely to mitigate than lowdisposable- income homeowners. (3) The stronger the place attachment among homeowners, the higher the likelihood they will mitigate. (4) Homeowners who have experienced effective mitigation measures in the past are more likely to mitigate than those who have not. To test these hypotheses, a survey was administered in five different neighborhoods throughout Orleans and Jefferson parishes having high concentrations of repeatedly flooded homes. The findings suggest severity of past flooding, disposable savings, strong relationships with neighbors, and discussion of flooding with neighbors are the strongest predictors of flood mitigation.

A Novel Electronic Ballast with Repeatedly Resonanting Ignition Circuit for Metal Halide Lamps

Huang, Dai-Jie 09 July 2007 (has links)
In this thesis, a novel electronic ballast that includes a repeatedly resonating ignition circuit is proposed for metal halide lamps. The proposed electronic ballast features a two-stage structure that comprises a power factor corrector and a full-bridge inverter used for current control, filtering and ignition. The full-bridge inverter consists of a leg operating at low-frequency with unidirectional switches and a leg operating at high frequency with bidirectional switches. The low-frequency side performs repetitive resonating on the load circuit with inductors and capacitors to accumulate a high voltage for ignition. Adjusting the duty-ratio of the high-frequency side allows for the regulation of the lamp current. The inductors and capacitors in the load circuit function not only producing the high ignition voltage but also filtering out high-frequency components, so that to drive the lamp with a low-frequency square-wave current. The proposed electronic ballast employing the full-bridge inverter with the specially designed control scheme and circuit parameters allows the metal halide lamp to tackle the demanding starting transient and steady state operation. With a simpler circuit structure and a reduced component count, the product cost will be much lower.

O princípio da confiança legítima sob a perspectiva das práticas reiteradamente observadas pelas autoridades administrativas em matéria tributária / The principle of legitimate expectations from the perspective of the practices observed repeatedly by administrative authorities on tax matters

Tilkian, Guilherme 23 May 2014 (has links)
Este trabalho versa sobre a aplicação do princípio da confiança legítima no Direito Tributário brasileiro, com foco no art. 100, inciso III, do Código Tributário Nacional (CTN), que trata das práticas reiteradamente observadas pelas autoridades administrativas. Parte-se da origem do princípio, aproximando a investigação por meio do princípio da segurança jurídica, da certeza do direito e da irretroatividade; em seguida, diferencia-se a proteção da confiança da boa-fé objetiva e prossegue-se pelo princípio da legalidade e a evolução jurisprudencial a respeito da conservação positiva ou negativa dos atos eivados de vícios quando deles se originaram direitos. Foca-se, então, nos requisitos para a configuração da confiança digna de proteção e os mecanismos de proteção positiva ou negativa dessa confiança. Desse ponto em diante, o estudo passa a desenhar a proteção da confiança legítima nos atos do Poder Executivo, por meio da análise do art. 100 do CTN, como fonte secundária de direito tributário. Conceituam-se as normas complementares, a origem e sua função, para então proceder-se ao exame específico das práticas reiteradamente observadas pelas autoridades administrativas e sua relação com o princípio da confiança legítima. Em seguida, analisa-se o parágrafo único do art. 100 do CTN para avaliar se são corretas a não atualização monetária da base de cálculo do tributo e a admissão de retroatividade parcial dos efeitos do reconhecimento da ilegalidade da prática administrativa em que confiou o contribuinte. Examina-se, de início, se a inércia da Administração Pública acerca de lançamento cuja homologação se dê de maneira tácita seria um silêncio positivo a configurar prática reiterada suficiente para dar respaldo à proteção do parágrafo único do art. 100 do CTN. O estudo avalia se, no caso dos tributos indiretos, pela impossibilidade de o contribuinte transferir ao consumidor a exação, justificaria uma proteção maior do que aquela conferida pelo próprio parágrafo único do art. 100 do CTN. Por derradeiro, a norma do art. 146 é confrontada com a do art. 100, inciso III, ambos do CTN, para fins de estabelecer os campos de aplicação de uma e de outra e em que medida elas se relacionam com a proteção da confiança legítima. / This work deals with the application of the principle of legitimate expectations in Brazilian tax law, focusing on Article 100, section III of the Brazilian Tax Code, which deals with the practices observed repeatedly by administrative authorities. The proposed scientific part of the origin of the principle, approaching research through the principle of legal security, legal certainty and non-retroactivity. Then differentiates the protection of reliable objective good faith and goes by the principle of legality and judicial developments regarding conservation (positive or negative) of the acts riddled with addictions when their rights originated. Focuses, then, on the requirements for setting up trust worthy of protection and the protection mechanisms positive or negative that trust. Thereafter the study is to draw back the protection of legitimate expectations in the acts of the Executive, through the analysis of Article 100 of the Internal Revenue Code, as secondary sources of tax law. Conceptualize themselves supplementary rules, the origin and function, down to the specific scope of practice repeatedly observed by the administrative authorities and their relation to the principle of legitimate expectations. Then we analyze the sole paragraph of article 100 of the Internal Revenue Code to assess whether it is correct not to monetary base tax calculation and admission of retroactivity of the effects of partial recognition of the illegality of administrative practice that relied on the taxpayer. Turning to specific issues initially analyzed is the inertia of public administration, which tacitly approves taxes charged for approval, would be a positive silence configuring repeated practice enough to give birth to protect the sole paragraph of article 100 of the Tax Code national. The study evaluates whether, in the case of indirect taxes, the inability of the taxpayer to transfer the consumer the exaction would justify greater protection than that afforded by the sole paragraph of article 100 of the Internal Revenue Code. Finally, the norm of Article 146 is confronted with Article 100, item III, both of the National Tax Code, for purposes of establishing fields of application of one and the other and the extent to which both relate to the protection of legitimate expectations.
