Energy and ancillary services joint market simulation

In order to develop a flexible simulator, a variety of models for Ancillary Services (AS) negotiation has been implemented in MASCEM – a multi-agent system competitive electricity markets simulator. In some of these models, the energy and the AS are addressed simultaneously while in other models they are addressed separately. This paper presents an energy and ancillary services joint market simulation. This paper proposes a deterministic approach for solving the energy and ancillary services joint market. A case study based on the dispatch of Regulation Down, Regulation Up, Spinning Reserve, and Non-Spinning Reserve services is used to demonstrate that the use of the developed methodology is suitable for solving this kind of optimization problem. The presented case study is based on CAISO real AS market data considers fifteen bids.

Smart Grid Market Using Joint Energy and Ancillary Services Bids

The power systems operation in the smart grid context increases significantly the complexity of their management. New approaches for ancillary services procurement are essential to ensure the operation of electric power systems with appropriate levels of stability, safety, quality, equity and competitiveness. These approaches should include market mechanisms which allow the participation of small and medium distributed energy resources players in a competitive market environment. In this paper, an energy and ancillary services joint market model used by an aggregator is proposed, considering bids of several types of distributed energy resources. In order to improve economic efficiency in the market, ancillary services cascading market mechanism is also considered in the model. The proposed model is included in MASCEM – a multi-agent system electricity market simulator. A case study considering a distribution network with high penetration of distributed energy resources is presented.

Consumer satisfaction with water, wastewater and waste services in Portugal

While the concept of consumer satisfaction is a central topic in modern marketing theory and practice, citizens' satisfaction with public services, and especially water and waste services, is a eld that still remains empirically rather unexplored. The following study aims to contribute to this area by analysing the determinants of user satisfaction in the water, wastewater and waste sector in Portugal, using a unique survey of 1070 consumers undertaken by the Portuguese Water and Waste Regulator ERSAR. I perform an analysis of the relation between overall service satisfaction and attributespeci c service satisfaction with an ordered logit model. I then explore if subjective consumer satisfaction can be re ected by ERSAR's technical performance indicators. The results suggest that overall consumer satisfaction is driven by consumer's satisfaction with speci c service aspects but unrelated to socioeconomic and demographic characteristics. Furthermore, I show that there is no monotonic association between ERSAR's technical performance indicators and consumers' levels of satisfaction.

“Weathering a Hidden Storm”: An Application of Andersen’s Behavioral Model of Health, and Health Services Use for Those with Diagnosable Anxiety Disorder

Abstract: Research has primarily focused on depression and mood disorders, but little research has been devoted to an examination of mental health services use amongst those with diagnosable anxiety disorder (Wittchen et al., 2002; Bergeron et al., 2005). This study examined the possible predicting factors for mental health services utilization amongst those with identifiable anxiety disorder in the Canadian population. The methods used for this study was the application of Andersen’s Behavioral Model of Health Services Use, where predisposing, need and enabling characteristics were regressed on the dependent variable of mental health services use. This study used the Canadian Community Health Survey (cycle 1.2: Mental Health and Well-Being) in a secondary data analysis. Several multiple logistics models predicted the likelihood to seek and use mental health services. Predisposing characteristics of gender and age, Enabling characteristics of education and geographical location, and those with co-occurring mood disorders were at the greatest increased likelihood to seek and use mental health services.

Unaccompanied minors in Canada: How social and legal services affect their lives in Ontario

This qualitative research examines how service provisions affect lives of unaccompanied minors in Canada. In this study I utilized a semi-structured individual interview method. Among thirteen participants in my study, five came to Canada as unaccompanied minors and eight are professionals involved with service providing organizations in the Niagara region. The unaccompanied children that I interviewed had mixed experiences. Social and legal supports were made available to some of them while one was deported. This paper employs Bhabha’s postcolonial perspective and Foucault’s governmentality to illustrate unaccompanied minors’ post-arrival situation in Canada. This paper also attempts to look at children’s rights from Hanson and Nieuwenhuys’s (2013) perspective of living rights, social justice and translations. This paper explores how the change in recent immigration law affects the lives of unaccompanied minors. Findings of this study suggest that it is important to have a consensus on the definition of an unaccompanied minor; improved data collection and record-keeping on the number of unaccompanied minors; and, having a government-approved follow up mechanism. The study recommends policy makers, service providers and scholars pay increased attention to the experiences of unaccompanied minors to ensure that adequate social and legal services are offered to an unaccompanied minor in Canada.

Wait Times to Rheumatology and Rehabilitation Services for Persons with Arthritis in Quebec

L’arthrite est l’une des causes principales de douleur et d’incapacité auprès de la population canadienne. Les gens atteints d’arthrite rhumatoïde (AR) devraient être évalués par un rhumatologue moins de trois mois suivant l’apparition des premiers symptômes et ce afin de débuter un traitement médical approprié qui leur sera bénéfique. La physiothérapie et l’ergothérapie s’avèrent bénéfiques pour les patients atteints d’ostéoarthrite (OA) et d’AR, et aident à réduire l’incapacité. Notre étude a pour but d’évaluer les délais d’attente afin d’obtenir un rendez-vous pour une consultation en rhumatologie et en réadaptation dans le système de santé public québécois, et d’explorer les facteurs associés. Notre étude est de type observationnel et transversal et s’intéresse à la province de Québec. Un comité d’experts a élaboré trois scénarios pour les consultations en rhumatologie : AR présumée, AR possible, et OA présumée ; ainsi que deux scénarios pour les consultations en réadaptation : AR diagnostiquée, OA diagnostiquée. Les délais d’attente ont été mesurés entre le moment de la requête initiale et la date de rendez-vous fixée. L’analyse statistique consiste en une analyse descriptive de même qu’une analyse déductive, à l’aide de régression logistique et de comparaison bivariée. Parmi les 71 bureaux de rhumatologie contactés, et pour tous les scénarios combinés, 34% ont donné un rendez-vous en moins de trois mois, 32% avaient une attente de plus de trois mois et 34% ont refusé de fixer un rendez-vous. La probabilité d’obtenir une évaluation en rhumatologie en moins de trois mois est 13 fois plus grande pour les cas d’AR présumée par rapport aux cas d’OA présumée (OR=13; 95% Cl [1.70;99.38]). Cependant, 59% des cas d’AR présumés n’ont pas obtenu rendez-vous en moins de trois mois. Cent centres offrant des services publics en réadaptation ont été contactés. Pour tous les scénarios combinés, 13% des centres ont donné un rendez-vous en moins de 6 mois, 13% entre 6 et 12 mois, 24% avaient une attente de plus de 12 mois et 22% ont refusé de fixer un rendez-vous. Les autres 28% restant requéraient les détails d’une évaluation relative à l’état fonctionnel du patient avant de donner un rendez-vous. Par rapport aux services de réadaptation, il n’y avait aucune différence entre les délais d’attente pour les cas d’AR ou d’OA. L’AR est priorisée par rapport à l’OA lorsque vient le temps d’obtenir un rendez-vous chez un rhumatologue. Cependant, la majorité des gens atteints d’AR ne reçoivent pas les services de rhumatologie ou de réadaptation, soit physiothérapie ou ergothérapie, dans les délais prescrits. De meilleures méthodes de triage et davantage de ressources sont nécessaires.

Being a bereaved parent : early bereavement experiences and perspectives on paediatric palliative care and bereavement services

La mort d'un enfant est considérée comme l'une des expériences les plus difficiles à laquelle une personne puisse faire face. Les cliniciens, les hôpitaux et plusieurs organismes ont pour objectif d’aider les parents endeuillés, mais leurs efforts sont compliqués par un manque de recherche dans le domaine du deuil parental. Cette thèse est composée de trois articles, soit deux revues de littérature et une étude empirique, qui tentent de combler cette lacune et d’informer les services en soins palliatifs pédiatriques et les services de soutien au deuil en particulier. Le premier article porte sur les besoins des patients recevant des soins palliatifs pédiatriques et de leurs familles. Par le biais d’un méta-résumé de la recherche descriptive et qualitative récente, 10 domaines de besoins ont été identifiés qui correspondent aux lignes directrices actuelles en soins palliatifs pédiatriques et de fin de vie. Ces besoins sont présentés de manière à être facilement applicables à la pratique. Cependant, les résultats mettent aussi en évidence plusieurs aspects des soins identifiés comme déficitaires ou problématiques qui mériteraient une attention particulière dans le cadre de politiques futures. Dans le deuxième article, l'objectif était de résumer une vaste littérature d'une manière utile aux cliniciens. À cette fin, une synthèse narrative a permis d’intégrer la recherche quantitative et qualitative dans le domaine du deuil parental. Les résultats mettent en évidence les éléments susceptibles de favoriser l’adaptation des parents au deuil, éléments qui suggèrent par le fait même des avenues possibles de soutien et d'intervention. Cette synthèse a cependant cerné dans la littérature certaines failles méthodologiques qui rendent l'applicabilité clinique des résultats difficile. L'objectif du troisième article était d'informer les services de suivi et de soutien au deuil auprès des parents en se renseignant directement auprès de parents endeuillés. À cette fin, 21 parents (dont 8 couples) et 7 membres du personnel impliqués dans des activités de suivi de deuil de 2 hôpitaux pédiatriques ont été interrogés dans le cadre d’une description interprétative, et l'application clinique des résultats a été vérifiée par le biais de réunions avec des collaborateurs de recherche et les décideurs des centres hospitaliers. Les résultats décrivent comment les parents ont fait face à leur détresse dans la phase précoce de leur deuil, ainsi que leurs points de vue sur la façon dont les divers services de suivi de deuil ont été aidants. Les résultats suggèrent que les parents gèrent leurs sentiments intenses de douleur par une alternance de stratégies axées soit sur leur deuil ou sur leur quotidien et que dans plusieurs cas leurs relations avec autrui les ont aidé. Cette étude a également permis d'élucider la façon dont divers services de soutien aide les parents à aborder leur deuil. Les implications cliniques de ces résultats sont discutées ainsi que des recommandations à l’intention de ceux qui sont impliqués dans la provision des services en deuil.

Studies on Landfill Leachate Transportation and Its Impact on Soil Characteristics

Leachate from an untreated landfill or landfill with damaged liners will cause the pollution of soil and ground water. Here an attempt was made to generate knowledge on concentrations of all relevant pollutants in soil due to municipal solid waste landfill leachate and its migration through soil and also to study the effect of leachate on the engineering properties of soil. To identify the pollutants in soil due to the leachate generated from municipal solid waste landfill site, a case study on an unlined municipal solid waste landfill at Kalamassery has been done. Soil samples as well as water samples were collected from the site and analysed to identify the pollutants and its effect on soil characteristics. The major chemicals in the soil were identified as Ammonia, Chloride, Nitrate, Iron, Nickel, Chromium, Cadmium etc.. Engineering properties of field soil samples show that the chemicals from the leachate of landfill may have effect on the engineering properties of soil. Laboratory experiments were formulated to model the field around an unlined MSW landfill using two different soils subjected to a synthetic leachate. The Maximum change in chemical concentration and engineering property was observed on soil samples at a radial distance of 0.2 m and at a depth of 0.3 m. The pollutant (chemicals) transport pattern through the soil was also studied using synthetic leachate. To establish the effect of pollutants (chemicals) on engineering properties of soil, experiments were conducted on two types soils treated with the synthetic chemicals at four different concentrations. Analyses were conducted after maturing periods of 7, 50, 100 and 150 days. Test soils treated with maximum chemical concentration and matured for 150 days were showing major change in the properties. To visualize the flow of pollutants through soil in a broader sense, the transportation of pollutants through soil was modeled using software ‘Visual MODFLOW’. The actual field data collected for the case study was used to calibrate the modelling and thus simulated the flow pattern of the pollutants through soil around Kalamassery municipal solid waste landfill for an extent of 4 km2. Flow was analysed for a time span of 30 years in which the landfill was closed after 20 years. The concentration of leachate beneath the landfill was observed to be reduced considerably within one year after closure of landfill and within 8 years, it gets lowered to a negligible level. As an environmensstal management measure to control the pollution through leachate, permeable reactive barriers are used as an emerging technology. Here the suitability of locally available materials like coir pith, rice husk and sugar cane bagasse were investigated as reactive media in permeable reactive barrier. The test results illustrates that, among these, coir pith was showing better performance with maximum percentage reduction in concentration of the filtrate. All these three agricultural wastes can be effectively utilized as a reactive material. This research establishes the influence of leachate of municipal solid waste landfill on the engineering properties of soil. The factors such as type of the soil, composition of leachate, infiltration rate, aquifers, ground water table etc., will have a major role on the area of influence zone of the pollutants in a landfill. Software models of the landfill area can be used to predict the extent and the time span of pollution of a landfill, by inputting the accurate field parameters and leachate characteristics. The present study throws light on the role of agro waste materials on the reduction of the pollution in leachate and thus prevents the groundwater and soil from contamination

Connecting the Water and Carbon Cycles for the Generation of Food Security and Ecosystem Services

Water scarcity and food insecurity are pervasive issues in the developing world and are also intrinsically linked to one another. Through the connection of the water cycle and the carbon cycle this study illustrates that synergistic benefits can be realized by small scale farmers through the implementation of waste water irrigated agroforestry. The WaNuLCAS model is employed using La Huerta agroforestry site in Texcoco, South Central Mexico, as the basis for parameterization. The results of model simulations depicting scenarios of water scarcity and waste water irrigation clearly show that the addition of waste water greatly increases the agroforestry system’s generation of crop yields, above- and below-ground biomass, soil organic matter and carbon storage potential. This increase in carbon sequestration by the system translates into better local food security, diversified household income through payments for ecosystem services and contributes to the mitigation of global climate change.
