Tutela antecipada em processos coletivos: a racionalidade de sua concessão / Preliminary injunction in class actions: the rationality of its decree

Leonardo Augusto dos Santos Lusvarghi 20 April 2012 (has links)
O presente trabalho trata das tutelas antecipadas em processos coletivos a partir do tratamento legal diferenciado dado pelo legislador e das considerações jurídicas não-legais próprias do seu objeto. Por meio de estudo comparado, o trabalho pretende enfrentar as dificuldades inerentes à complexidade das relações envolvidas, dando especial atenção à função do desenho da tutela antecipada, ao conceito de irreparabilidade e irreversibilidade, e à aplicação dos requisitos balance of hardships e interesse público. A análise passa pelas teorias da decisão judicial a fim de dar perspectiva à necessidade de um procedimento deliberativo mais complexo e minucioso para fins de responsividade das decisões judiciais. Ademais, explorase a adjudicaçãoo pragmática elaborada por Richard Posner e pretende-se sua aplicação aos processos coletivos por meio da introdução da análise de custo-benefício como procedimento decisório welfarista moralmente relevante, mas não moralmente decisivo. / This thesis focuses on the preliminary injunctions in class actions, having as the starting point the different legal treatment given by the legislator and the non-legal jurídical considerations that flows from its nature. By means of a comparative study, the work intends to face the inherent difficuties of the complex relationships entailed, paying extra attention to the function of the preliminary injunction structure, to the concept of irreparability and irreversibility, and to the way the requirements of balance of hardships and public interest apply. The analysis passes through the theories of the judicial decision-making process in order to give perspective to the need of more complex deliberative proceedings which must be done in full details to reach accountability. Furthermore, the work explores the pragmatic adjudication elaborated by Richard Posner and intends its application to class actions by means of the introduction of cost-benefit analysis as a welfarist decision-making procedure that is morally relevant, but not morally decisive.

Avaliou-se que 59% das APP's de vegetação ripária encontram-se ocupadas por atividades agropecuárias e que o custo de oportunidade da terra apresenta-se como principal custo inibidor da adoção de medidas para adequação destas áreas. A adoção de práticas que visam a conservação do solo nas áreas de cultivo têm grande potencial de redução da perda de solo, contudo o custo de manutenção destas práticas desestimula sua ampla adoção na microbacia. Os resultados da análise econômica de custos e benefícios apontam para a viabilidade da adoção de medidas mitigadoras de impactos agro-ambientais em todos os sistemas agrícolas estudados (relação B/C sempre maior que 1), mas a redução observada no VPL dos sistemas aponta para a necessidade da elaboração de políticas e de incentivos econômicos que compensem as perdas que incorrem sobre os agricultores / Abstract: This work analyzes the economic viability of a private mitigation project for agroenvironmental impacts in the Oriçanguinha watershed. Approximately 59% of riparian zones are occupied by agricultural activities and the opportunity cost of land is primarily responsible for inhibiting the environmental adjustment of these areas. The adoption of conservation soil practices on agricultural land has the potential to reduce erosion, however the maintenance cost of these practices does not stimulate their adoption in the watershed. Cost-benefit analyses point to the economic viability of agro-environmental mitigation practices in alI agricultural systems studied (B/C relation larger thanl) but the observed reduction of Net Present Value in the systems suggests the need for polices and economic incentives that compensate farmer's economic loses / Mestrado / Economia do Meio Ambiente / Mestre em Desenvolvimento Econômico

Diabeettisen retinopatian valokuvaseulonnan kustannukset ja hyödyt sekä näkövammaisten elämänlaatu ja kuolleisuus

Pajunpää, H. (Hannu) 07 May 1999 (has links)
Abstract The purpose of this study was to compare the effectiveness, costs and benefits of screening for diabetic retinopathy with retinal photography and with ophthalmoscopic examination in health care centres by primary care physicians, and also to study the quality of life and mortality of visually impaired diabetics. There are about 150 000 diabetics in Finland. There were 881 visually impaired persons due to diabetic retinopathy in the Finnish Register of Visually Impaired Patients in 1994 (1122 in 1997). Laser photocoagulation has proved to be an effective treatment in diabetic retinopathy preventing visual loss. The screening methods are ophthalmoscopic examination and retinal photography. The incidence of retinopathy was calculated from the photogaphy screening in the Oulu Health Care Centre in 1987 (N = 1015), in 1991–92 (N = 1844) and in 1993–94 (N = 1484). The ophthalmoscopy screening was studied from patients' records (N = 242) in the Raahe Health Care Centre. Out of 120 visually impaired persons with diabetic retinopathy in the province of Pohjois-Pohjanmaa, 50 were interviewed by the health care secretary. The study included cost-benefit analysis for the costs of screening and treatment of diabetic retinopathy compared with the costs of visual impairment. Furthermore the quality of life of patients with visual impairment due to diabetic retinopathy was studied using the Nottingham Health Profile questionaire (NHP) and compared with diabetic patients without visual impairment. The mortality rate of visually impaired patients was compared to that of diabetic retinopathy patients who had been treated with laser photocoagulation. The incidence of all diabetic retinopathy was 9.4 per cent per year and 2.8 per cent per year for moderate to severe retinopathy, and in patients with no insulin in their treatment the incidence of all retinopathy was 3.0 and 1.2 per cent per year respectively. The screening costs per diabetic person screened were 148 Finnish marks (FIM) in the photographic method and 68 FIM in the ophthalmoscopic method. It was calculated that 156 visual impairment cases could be prevented per year in Finland with the photographic method. The screening and treating costs in finding one preventable case of visual impairment were 185 000 FIM. The costs of visual impairment were 594 000 FIM per patient. So retinal photography screening and treatment of diabetic retinopathy could lead to savings of 63.9 million FIM per yearly screening in Finland. The quality of life of visually impaired persons was worse than that of other diabetics in two dimensions of the NHP, Energy and Mobility. In the second part of the NHP, the quality of life of visually impaired persons was worse than that of other diabetics in all questions except working. The mortality rate of visually impaired persons, 14.5 per cent per year was twice as high as that of diabetic patients treated with laser photocoagulation. The incidence of diabetic retinopathy in Finland was about the same as in other industrialized countries. Retinal photography seemed to be a cost-effective screening method for preventing visual impairment and the cost benefit ratio of screening and treating diabetic retinopathy was 3.2. The quality of life of visually impaired patients was worse and mortality risk higher than that of other diabetics. / Tiivistelmä Tarkoituksena oli tutkia perusterveydenhuollossa silmänpohjakuvauksella tai oftalmoskopialla tehdyn diabeettisen retinopatian seulonnan vaikuttavuutta, kustannuksia ja hyötyjä näkövammaisuuden ehkäisyssä sekä diabeettisen retinopatian ilmaantuvuutta, ja sen vuoksi näkövammaisten elämänlaatua ja kuolleisuutta. Suomessa on noin 150 000 diabeetikkoa. Diabeettisen retinopatian aiheuttama näkövamma oli Näkövammarekisterin mukaan vuoden 1994 alussa 881:lla suomalaisella (vuoden 1997 lopussa 1122:lla suomalaisella). Diabeettisen retinopatian aiheuttamaa näkövammaisuutta voidaan ehkäistä ajoissa toteutetulla silmänpohjan laser-fotokoagulaatiohoidolla. Uusien tautitapausten löytämiseksi käytetään oftalmoskopiaa ja silmänpohjakuvausta. Diabeettisen retinopatian ilmaantuvuus laskettiin Oulussa vuosina 1987 (N = 1015), 1991–92 (N = 1844) ja 1993–95 (N = 1484) toteutettujen silmänpohjakuvausten perusteella. Diabeettisen retinopatian oftalmoskooppista toteamista tutkittiin Raahen seudun terveyskeskuksen diabetesvastaanoton potilaiden sairauskertomuksista (N = 242). Seulontamenetelmien tehokkuutta arvioitiin kustannusvaikuttavuusanalyysillä ja diabeettisen retinopatian seulonnan ja hoidon hyötyä näkövammaisuuden ehkäisyssä kustannus-hyötyanalyysillä. Pohjois-Pohjanmaalta diabeettisen retinopatian johdosta näkövammarekisteriin ilmoitetuista (N = 120) haastateltiin tavoitetut 50 henkilöä. Haastatelluilla näkövammaisille sekä Oulussa vuosina 1991–92 silmänpohjakuvaukseen osallistuneille tehtiin elämänlaatukysely NHP-mittarilla. Elämänlaatua ja kuolleisuutta tutkittiin tapaus-verrokki asetelmalla. Tutkimuksen mukaan Diabeettisen retinopatian koko ilmaantuvuus oli 9,4 % vuodessa ja diabeetikoilla, joiden hoidossa ei käytetty insuliinia, ilmaantuvuus oli 3,0 % vuodessa. Vaikean tausta- ja proliferatiivisen retinopatian ilmaantuvuus oli vastaavasti 2,8 % ja 1,2 % vuodessa. Silmänpohjakuvaukseen perustuvan seulonnan ja laserhoidon kustannukset olivat 192 mk seulottua kohti. Silmänpohjakuvausseulonnalla olisi tämän tutkimuksen mukaan mahdollista estää Suomessa vuosittain 156 näkövammaa kustannusten ollessa noin 185 000 mk estettyä näkövammaa kohti. Yhden näkövamman kustannukset olivat yhteensä 594 000 mk. Silmänpohjakuvaukseen perustuvalla seulonnalla olisi mahdollista säästää noin 63,9 milj. mk vuodessa edellyttäen, että tulokset ovat yleistettävissä koko maahan. Diabeettisen retinopatian johdosta näkövammaisten elämänlaatu oli selvästi muita diabeetikkoja huonompi NHP-mittarin ulottuvuuksilla tarmokkuus ja liikkuminen sekä useilla keskeisillä elämänalueilla. Näkövammaisten diabeetikkojen kuolemanriski oli yli kaksinkertainen laserhoidettuhin näkönsä säilyttäneiisiin diabeettista retinopatiaa sairastaviin verrattuna. Tutkimuksen mukaan diabeettisen retinopatian ilmaantuvuus oli Suomessa samalla tasolla kuin muissa teollistuneissa maissa. Silmänpohjakuvaussseulonta osoittautui taloudellisesti kannattavaksinäkövammojen ehkäisyssä. Näkövammaisuus heikensi diabeetikkojen elämänlaatua ja lisäsi kuolemanriskiä.

Design and Implementation of a Tool for Automating Cluster Configuration : For a Software Defined Storage System

Marakani, Sindhusha January 2015 (has links)
Context Traditional storage systems are proving to be inefficient to handle the growing storage need of a modern IT organization. The need for a cost effective and scalable storage framework has led to the development of a Software Defined Storage (SDS) solution. SDS can be defined as an enterprise class distributed storage solution that uses standard hardware, with all the important storage and management functions performed by an intelligent software. Configuring and maintenance of these storage clusters require converting an SDS from any unknown state to a predefined, known state. This configuration of the SDS is best done with minimal human intervention, to ensure minimal errors and save the man hours spent in the configuration process. Objectives A tool for automatic configuration of a SDS storage cluster has been designed and implemented. The tool has later been used to study the man hours saved in the configuration of the SDS cluster. The study also involves a cost-benefit analysis to estimate the break-even point for such a tool to motivate the automation of a SDS cluster configuration process. Methodology In this study, experts from the field of Software Defined Storage have been interviewed to identify interesting and most common states of a SDS cluster. Later a tool was build such that it communicates with the underlying SDS storage cluster to configure it into one of the identified final states. This tool built was later used to conduct experiments wherein the amount of man hours saved by automating the process of cluster configuration was calculated.    Results The tool built was validated through results obtained from the experiments which show that the work time involved in the process of cluster configuration is reduced by 90% - 96% (based on the complexity of the cluster configuration). Also, the lead times of the configuration process are similar when configuring simple states but is greatly reduced by automation when performing complex configurations. Conclusions Similar to any other software automation, the process of automating the configuration of a distributed storage cluster has proven to be beneficial. Automating the process of cluster configuration saves time, reduces human errors induced in the configuration process and improves repeatability of the configuration process. Through the cost-benefit analysis of the complete process, the use of the tool beyond 20 days is deemed profitable for the organization.

Biogas production potential and cost-benefit analysis of harvesting wetland plants (Phragmites australis and Glyceria maxima).

Gilson, Eoin January 2017 (has links)
Biogas production from energy crops grown on arable land often competes with food and feed production. Wetland plants offer an alternative source of biomass as well as offering a number of environmental benefits such as nutrient removal from wastewaters, carbon sequestration and reducing the use of mineral fertilizer. The aim of this study is to investigate the effect of harvest time on biogas production of Phragmites australis and Glyceria maxima and to perform a cost-benefit analysis of using these wetland plants as a substrate for biogas production. The results of the batch experiment show that the overall biogas production and specific methane yields of biomass harvested in June was higher than biomass harvested in September due the increased lignocellulosic nature of the more mature September plant. The cost-benefit showed that in Sweden it is not currently profitable to solely use wetland plants for biogas production. For both species the highest costs were seen in the June harvested biomass, this was due to the much higher fresh weight and increased transportation costs. For both species the highest revenues generated were the June harvested biomass, this was due to the higher specific methane yields. It was found that the harvest time that was closest to profitability from both species was the June harvest for Phragmites australis. Although the costs were higher for harvesting in June, this was outweighed by the higher amount of electricity produced for this scenario. If transportation distance was to be increased it could result in September being the favourable harvest time. Therefore, individual circumstances of the farmers could decide which is the optimal harvest time. Although solely using wetland plants for biogas production is not currently profitable, co-digestion and pre-treatment are options to investigate that could change this. Also if a greater financial value is put on the socioeconomic benefits such as increased biodiversity, aesthetic value and global warming mitigation it may be financially viable in the future.

Caractérisation et évaluation économique de la vulnérabilité des exploitations agricoles aux inondations / Characterization and economic evaluation of farm vulnerability to flooding

Bremond, Pauline 12 December 2011 (has links)
L'échec des politiques structurelles de gestion des inondations à réduire les dommages a orienté les décideurs publics vers la restauration de zones de rétention et la réduction de la vulnérabilité. L'évaluation économique de ces politiques requiert une évaluation fine des dommages agricoles car ils contribuent fortement à déterminer leur efficacité. Or, les méthodes existantes n'intègrent que les pertes de récolte. Considérant que la vulnérabilité des exploitations agricoles dépend de la sensibilité et de la capacité à se remettre en route, entraînant respectivement des dommages directs et induits sur l'activité, nous proposons un modèle conceptuel de vulnérabilité permettant l'évaluation de l'ensemble de ces dommages. Trois profils d'exploitants sont définis selon la possibilité de mobiliser des ressources externes (main d'œuvre et matériel) pour la remise en route. Le profil Interne ne dispose d'aucune ressource externe contrairement aux profils Prestation et Solidarité. Après implémentation, le modèle a permis d'évaluer les dommages de trois exploitations types sur le Rhône aval avec une valorisation financière puis économique. Les dommages supportés par les exploitants de profil Interne sont plus élevés que ceux des deux autres profils. Les dommages évités par la mise en place de mesures de réduction de la vulnérabilité sur ces trois exploitations sont ensuite évalués. Nous montrons que les mesures sont plus efficaces et peuvent être mises en œuvre avec un ratio bénéfice-coût supérieur à un, pour les exploitations fréquemment inondées. Elles sont également plus efficaces pour les profils Interne, la mise en œuvre de la solidarité se dégageant comme une mesure intéressante pour toutes les exploitations. / The failure of structural flood control to mitigate economic losses has lead to a shift towards new policies: floodplain restoration and vulnerability reduction. The economic appraisal of these policies requires an in-depth evaluation of agricultural damage as they are key indicators to determine the efficiency of these policies. However, existing methods only consider harvest loss. We consider that farm vulnerability depends on sensitivity and ability to recover leading respectively to direct damage and induced damage on activity. Based on this, we propose a vulnerability model which allows evaluating the whole of these damages. Three farmer's profiles are defined depending on their ability to access to external resources (workforce and equipment) to recover after flooding. The “Internal” profile has no external resource as opposed to the “Service” and “Solidarity” profiles which can respectively rely on service providing and solidarity. The model is applied to evaluate damages on three farm types of the Rhône River downstream area with a financial and economic valuation. This reveals that damages endured by the profile “Internal” are much higher than those of the two other profiles. Then, avoided damages resulting from the implementation of mitigation measures to reduce vulnerability are evaluated. We prove that these measures are more efficient and can be implemented with Benefit-Cost ratio higher than one, only for the frequently flooded farms. Mitigation measures are also more efficient for the profile “Internal”. To organize solidarity between farms emerges as one of the most interesting measure for all farm types.

Fiabilité du temps de transport : Mesures, valorisation monétaire et intégration dans le calcul économique public / Travel time reliability : Measurement, monetary valuation and cost-benefit implication

Stéphan, Maïté 09 November 2015 (has links)
Cette thèse aborde la question de la fiabilité du temps de transport. L’étude de la fiabilité du temps de transport trouve ses sources dans le fait que, dans bien des situations, le temps de transport n’est pas certain, mais aléatoire. De nombreux évènements peuvent en effet modifier le temps de transport prévu par les opérateurs ou espéré par les usagers. Par ailleurs, lors de l’évaluation socioéconomique de projets d’investissement en infrastructure de transport, il peut exister un arbitrage entre gain de temps et gain de fiabilité. Or, comme la fiabilité est encore à l’heure actuelle, difficilement intégrable dans ce type d’évaluation, ces projets d’investissement voient leur rentabilité collective sous-estimée conduisant à leurs reports. Il émerge ainsi trois problématiques majeures relatives à l’étude de la fiabilité du temps de transport : sa mesure, sa valorisation monétaire (i.e. la disposition à payer des individus pour améliorer la fiabilité du temps de transport) et enfin, sa prise en compte dans les analyses coûts-avantages. Un premier chapitre permet d’adapter les mesures usuelles de la fiabilité du temps de transport appliquées dans le cadre du transport routier, aux modes de transport collectif (fer et aérien plus particulièrement). Nous proposons également une nouvelle mesure de la fiabilité, le Delay-at-Risk (DaR) inspiré de la littérature financière. Le DaR est une transposition de la mesure de la Value-at-Risk (V aR) à l’économie des transports. Cette mesure est plus utile du point de vue des usagers pour la planification des trajets avec correspondance que les autres mesures. Le deuxième chapitre a pour principal objectif de déterminer la disposition à payer des individus pour améliorer la fiabilité du temps de transport. Nous proposons un cadre théorique inspiré de la théorie de la décision en univers risqué à partir duquel nous définissons la préférence des individus à l’égard de la fiabilité (i.e. reliabilityproneness) ainsi que la prudence. Nous développons des nouvelles mesures de la fiabilité du temps de transport, exprimées comme des primes de risque : la reliability-premium et la V OR. La reliability-premium détermine le temps de transport maximum supplémentaire qu’un individu est prêt à accepter pour supprimer l’intégralité du risque sur le temps de transport. La V OR, quant à elle, se définit comme la disposition maximale à payer d’un individu pour supprimer l’intégralité du risque sur le temps de transport. Par ailleurs, nous établissons également les conséquences sur la valeur du temps (V TTS) et de la fiabilité (V OR), de la prise en considération de l’attitude à l’égard du risque sur le temps de transport des usagers (aversion et prudence). Le dernier chapitre de cette thèse a pour objet d’intégrer la fiabilité dans les évaluations socioéconomiques de projet d’investissement et plus particulièrement dans la détermination du surplus des usagers. Nous mettonsen exergue un effet de diffusion des gains de fiabilité par rapport aux gains de temps. Ainsi, nous proposons des recommandations quant à l’arbitrage entre les projets générateurs de gain de temps et de gain de fiabilité en fonction des valeurs monétaires du temps (V TTS) et de la fiabilité (V OR). / This thesis deals with the issue of travel time reliability. The study of travel time reliability emerges from the fact that in many situations, travel time is random. Many events can change the travel time forecasted by operators or expected by users. Moreover, a tradeoff may exist between time and reliability benefits when evaluating socio economic appraisal of transport infrastructure. However, since reliability is still difficult to integrate in this type of evaluation, investment projects’ collective profitability is underestimated and often postponed. Thus, three main issues of travel time reliability analysis emerge: measurement, monetary valuation and implication for cost benefit analysis. This thesis is organized in three chapters. The first chapter adapts the measure of travel time reliability typically used in the road transport context to the collective modes (rail and air, in particular). We also develop a new reliability measure: the Delay-at-Risk (DaR). DaR is an implementation of the Value-at-Risk (V aR) measure into the transport economic framework. The DaR seem to be relevant and understandable information for the users, especially to plan their travel and avoid missing their connections. The main objective of the second chapter is to define the users’ willingness to pay to improve travel time reliability. We present a theoretical framework based on decision theory under risk. We introduce the concept of reliability-proneness (i.e. travel time risk aversion) and prudence. We develop new measures of travel time reliability expressed as risk premium: the reliability-premium and V OR. The reliability-premium is the maximum amount of additional travel time that an individual is willing to accept to escape all the risk of travel time. The V OR is defined as the maximum monetary amount that an individual is willing to pay to escape all the risk of travel time. Furthermore, we also establish the link with attitudes towards risks of travel time (aversion and prudence) and the impact of the value of travel time (V TTS) and the value of reliability (V OR). The final chapter of this thesis integrates reliability in investments project’s socioeconomic appraisal. More particularly, it allows to determine users’ surplus valuation. We highlight a diffusion effect of reliability benefits with regard to travel time benefits. Thus, we propose recommendations regarding the tradeoff between projects that generate time benefits compared with reliability benefits, according to the monetary values of travel time(V TTS) and reliability (V OR).

The Impact of Increased Number of Acute Care Beds to Reduce Emergency Room Wait Time

McKay, Jennifer January 2015 (has links)
Reducing ED wait times is a top health care priority for the Ontario government and hospitals in Ontario are incentivised to meet provincial ED wait time targets. In this study, we considered the costs and benefits associated with increasing the number of acute-care beds to reduce the time an admitted patient spends boarding in the ED. A shorter hospital LOS has often been cited as a potential benefit associated with shorter ED wait times. We derived a multivariable Cox regression model to examine this association. We found no significant association between ED boarding times and the time to discharge. Using a Markov model, we estimated an increased annual operating cost of $2.1m to meet the prescribed wait time targets. We concluded that increasing acute-care beds to reduce ED wait times would require significant funding from hospitals and would have no effect on total length of stay of hospitalized patients.
