An intelligent network control system for plug-in electric vehicles and the associate communication mechanism

The development of an intelligent plug-in electric vehicle (PEV) network is an important research topic in the smart grid environment. An intelligent PEV network enables a flexible control of PEV charging and discharging activities and hence PEVs can be utilized as ancillary service providers in the power system concerned. Given this background, an intelligent PEV network architecture is first developed, and followed by detailed designs of its application layers, including the charging and discharging controlling system, mobility and roaming management, as well as communication mechanisms associated. The presented architecture leverages the philosophy in mobile communication network buildup

Managing intravenous medications in the non-hospital setting: An ethnographic investigation

Little published information exists about the issues involved in conducting complex intravenous medication therapy in patients' homes. An ethnographic study of a local hospital-in-the-home program in the Australian Capital Territory explored this phenomenon to identify those factors that had an impact on the use of medicine in the home environment. This article focuses on one of the three themes identified in the study-Clinical Practice. Within this theme, topics related to the organization and management of intravenous medications, geography and diversity of patient caseload, and communication in the practice setting are discussed. These findings have important implications for policy development and establishment of a research agenda for hospital-in-the-home services.

Assessing exposure to polybrominated diphenyl ethers (PBDEs) for workers in the vicinity of a large recycling facility

Increased levels of polybrominated diphenyl ethers (PBDEs) can occur particularly in dust and soil surrounding facilities that recycle products containing PBDEs. This may be the source of increased exposure for nearby workers and residents. To investigate, we measured PBDE levels in soil, office dust and blood of workers at the closest workplace (i.e. within 100m) to a large automotive shredding and metal recycling facility in Brisbane, Australia. The workplace investigated in this study was independent of the automotive shredding facility and was one of approximately 50 businesses of varying types within a relatively large commercial/industrial area surrounding the recycling facility. Concentrations of PBDEs in soils were at least an order of magnitude greater than background levels in the area. Congener profiles were dominated by larger molecular weight congeners; in particular BDE-209. This reflected the profile in outdoor air samples previously collected at this site. Biomonitoring data from blood serum indicated no differential exposure for workers near the recycling facility compared to a reference group of office workers, also in Brisbane. Unlike air, indoor dust and soil sample profiles, serum samples from both worker groups were dominated by congeners BDE-47, BDE-153, BDE-99, BDE-100 and BDE-183 and was similar to the profile previously reported in the general Australian population. Estimated exposures for workers near the industrial point source suggested indoor workers had significantly higher exposure than outdoor workers due to their exposure to indoor dust rather than soil. However, no relationship was observed between blood PBDE levels and different roles and activity patterns of workers on-site. These comparisons of PBDE levels in serum provide additional insight into the inter-individual variability within Australia. Results also indicate congener patterns in the workplace environment did not match blood profiles of workers. This was attributed to the relatively high background exposures for the general Australian population via dietary intake and the home environment.

Re-examining habitual residence as the sole connecting factor in Hague Convention child abduction cases

This article critiques the usefulness of habitual residence as the sole connecting factor in Hague Convention child abduction cases. This is achieved by examining the quality of this jurisdiction in light of changes in the gender dynamics underpinning international parental child abduction and the transnational family phenomenon. Arguably, the child’s habitual residence as a home environment of the nature anticipated by the Convention’s drafters is an increasingly outdated construct. This is due to an increase in both the number of abducting primary-carer mothers, and their families’ growing mobility. Judicial determinations of habitual residence made during Conven- tion return proceedings are entrenched in the state-centric paradigm. This paradigm is becoming increasingly incompatible with the lives of families which experience international parental child abduction.

Privacy, modesty, hospitality and the design of Muslim homes in Australia

The home environment is conceptualised in prolific ways within the academic literature. A home is an unparalleled base for human settlement and habitation that embodies a sensorial space that is layered with personal memories and traces of history. The success of a home in providing a strong ‘sense of place’ depends on various factors such as geographical location, monetary funds or personal perceptions. A home too, is an influential medium that allows its dwellers to express, perform and continue their cultural traditions and religious faiths. Traditional Islamic teachings and practices involve guidelines that apply directly to the domestic space. The principles of privacy, modesty and hospitality are paramount to these guidelines and each has a significant influence upon the design of Muslim homes and the home owners’ or dwellers’ domestic behaviours. Despite a significant increase of Muslim population in Australia over the last decade, very little is known about their perceptions of domestic life and their use of domestic spaces within an Australian context. This research investigated on how Muslims in Brisbane live and adapt within their Australian homes and if these homes meet their personal and familial needs to perform their daily activities, as well as maintaining and practising their Islamic faiths and traditions. Specific attention has been given to their perceptions on tripartite principles of privacy, modesty, and hospitality (PMH) and how they achieve these three objectives. A qualitative case study approach was used to investigate six Muslim families living in four Brisbane suburbs, consisting of: a) Case Study 1: three Muslim families residing in one suburb of Brisbane and, b) Case Study 2: three international Muslim students living in three different Brisbane suburbs. This research indicates that apart from minor ‘design-related’ difficulties, case study participants were able to continue to perform their daily activities within their current homes through minor changes to the use of the available interior spaces. Above all, case study participants opined that their current Australian homes provide them with adequate safety and privacy for their families without any major disturbances. Insight gained from these cases suggests that greater research attention needs to be given to the potential development of Australian home designs that are adaptable to the ever-changing needs of the Australian multicultural society. Awareness of the multifactorial nature of the influences on Muslims’ perceptions of home and their use of domestic space is needed if architects, building designers, engineers and builders are to be properly equipped to meet the needs of their Muslim clients.

Lock the gate: Fracking, investor-state dispute settlement, and the Trans-Pacific Partnership

There has been much debate about the relationship between international trade, the environment, biodiversity protection, and climate change.The Obama Administration has pushed such issues into sharp relief, with its advocacy for sweeping international trade agreements, such as the Trans-Pacific Partnership and the Trans-Atlantic Trade and Investment Partnership. There has been much public concern about the impact of the mega-trade deals upon the protection of the environment. In particular, there has been a debate about whether the Trans-Pacific Partnership will promote dirty fracking. Will the Trans-Pacific Partnership transform the Pacific Rim into a Gasland?There has been a particular focus upon investor-state dispute settlement being used by unconventional mining companies. Investor-state dispute settlement is a mechanism which enables foreign investors to seek compensation from national governments at international arbitration tribunals. In her prescient 2009 book, The Expropriation of Environmental Governance, Kyla Tienhaara foresaw the rise of investor-state dispute resolution of environmental matters. She observed:'Over the last decade there has been an explosive increase of cases investment arbitration. This is significant in terms of not only the number of disputes that have arisen and the number of states that have been involved, but also the novel types of dispute that have emerged. Rather than solely involving straightforward incidences of nationalization or breach of contract, modern disputes often revolve around public policy measures and implicate sensitive issues such as access to drinking water, development on sacred indigenous sites and the protection of biodiversity.'In her study, Kyla Tienhaara observed that investment agreements, foreign investment contracts and investment arbitration had significant implications for the protection for the protection of the environment. She concluded that arbitrators have made it clear that they can, and will, award compensation to investors that claim to have been harmed by environmental regulation. She also found that some of the cases suggest that the mere threat of arbitration is sufficient to chill environmental policy development. Tienhaara was equally concerned by the possibility that a government may use the threat of arbitration as an excuse or cover for its failure to improve environmental regulation. In her view, it is evident that arbitrators have expropriated certain fundamental aspects of environmental governance from states. Tienhaara held: As a result, environmental regulation has become riskier, more expensive, and less democratic, especially in developing countries. This article provides a comparative analysis of the battles over fracking, investment, trade, and the environment in a number of key jurisdictions including the United States, Canada, Australia, and New Zealand. Part 1 focuses upon the United States. Part 2 examines the dispute between the Lone Pine Resources Inc. and the Government of Canada over a fracking moratorium in Quebec. Part 3 charts the rise of the Lock the Gate Alliance in Australia, and its demands for a moratorium in respect of coal seam gas and unconventional mining. Part 4 focuses upon parallel developments in New Zealand. This article concludes that Pacific Rim countries should withdraw from investor-state dispute settlement procedures, because of the threat posed to environmental regulation in respect of air, land, and water.

Polybrominated diphenyl ethers (PBDEs) in dust from primary schools in South East Queensland, Australia

PBDE concentrations are higher in children compared to adults with exposure suggested to include dust ingestion. Besides the home environment, children spend a great deal of time in school classrooms which may be a source of exposure. As part of the “Ultrafine Particles from Traffic Emissions and Children's Health (UPTECH)” project, dust samples (n=28) were obtained in 2011/12 from 10 Brisbane, Australia metropolitan schools and analysed using GC and LC–MS for polybrominated diphenyl ethers (PBDEs) -17, -28, -47, -49, -66, -85, -99, -100, -154, -183, and -209. Σ11PBDEs ranged from 11–2163 ng/g dust; with a mean and median of 600 and 469 ng/g dust, respectively. BDE-209 (range n.d. −2034 ng/g dust; mean (median) 402 (217) ng/g dust) was the dominant congener in most classrooms. Frequencies of detection were 96%, 96%, 39% and 93% for BDE-47, -99, -100 and -209, respectively. No seasonal variations were apparent and from each of the two schools where XRF measurements were carried out, only two classroom items had detectable bromine. PBDE intake for 8–11 year olds can be estimated at 0.094 ng/day BDE-47; 0.187 ng/day BDE-99 and 0.522 ng/day BDE-209 as a result of ingestion of classroom dust, based on mean PBDE concentrations. The 97.5% percentile intake is estimated to be 0.62, 1.03 and 2.14 ng/day for BDEs-47, -99 and -209, respectively. These PBDE concentrations in dust from classrooms, which are higher than in Australian homes, may explain some of the higher body burden of PBDEs in children compared to adults when taking into consideration age-dependant behaviours which increase dust ingestion.

Prevalence and developmental course of 'secret language'.

The prevalence and developmental course of supposed ‘secret language’ was examined in a cohort of twins and closely spaced singletons pairs, with systematic assessments at 20 months and again at 36 months. Two forms of apparent ‘secret language’ were examined: (1) shared understanding—speech directed generally but unintelligible to the parent, although apparently clearly understood within the child pair, and (2) private language directed exclusively to the other twin/sibling—not intelligible to the parent, but apparently clearly understood and used only within the child pair. Both occurred in singleton pairs, but the rate was much higher in twins. In most cases it seemed to be a developmental phenomenon occurring in the second year of life with the emergence of immature speech, and decreasing considerably over the next 16 months. A small group of children, primarily male twins, was reported to use a private language at 36 months. This group had poorer cognitive and language functioning, and was characterized by highly dependent relationships. Some aspects of the twins’ home environment were less stimulating and less responsive, most probably reflecting the abilities and relationships of the children. A follow-up of these children when they were ~6 years of age showed that language outcome was poor for the subgroup (n = 4) who did not develop normal language alongside the use of a private language.

Keltaista ja kimaltavaa : kodin ja koulun yhteistyöstä koulun ja kodin yhteyteen

Through this study I aim to portray connections between home and school through the patterns of thought and action shared in everyday life in a certain community. My observations are primarily based upon interviews, writings and artwork by people from home (N=32) and school (N=13) contexts. Through the stories told, I depict the characters and characteristic features of the home-school interaction by generations. According to the material, in the school days of the grandparents the focus was on discipline and order. For the parents, the focus had shifted towards knowledge, while for the pupils today, the focus lies on evaluation, through which the upbringing of the child is steered towards favourable outcomes. Teachers and those people at home hold partially different understandings of home-school interaction, both of its manifested forms and potentials. The forms of contact in use today are largely seen as one-sided. Yearning for openness and regularity is shared by both sides, yet understood differently. Common causes for failure are said to lie in plain human difficulties in communication and social interaction, but deeply rooted traditions regarding forms of contact also cast a shadow on the route to successful co-operation. This study started around the idea, that home-school interaction should be steered towards the ex-change of constructive ideas between both the home and school environments. Combining the dif-ferent views gives to something to build upon. To test this idea, I drafted a practice period, which was implemented in a small pre-school environment in the fall of 1997. My focus of interest in this project was on the handling of ordinary life information in the schools. So I combined individual views, patterns of knowledge and understanding of the world into the process of teaching. Works of art and writings by the informants worked as tools for information processing and as practical forms of building home-school interaction. Experiences from the pre-school environ-ment were later on echoed in constructing home-school interaction in five other schools. In both these projects, the teaching in the school was based on stories, thoughts and performances put to-gether by the parents, grandparents and children at home. During these processes, the material used in this study, consisting of artwork, writings and interviews (N=501), was collected. The data shows that information originating from the home environments was both a motivating and interesting addition to the teaching. There even was a sense of pride when assessing the seeds of knowledge from one’s own roots. In most cases and subjects, the homegrown information content was seamlessly connected to the functions of school and the curriculum. This project initiated thought processes between pupils and teachers, adults, children and parents, teachers and parents, and also between generations. It appeared that many of the subjects covered had not been raised before between the various participant groups. I have a special interest here in visual expression and its various contextual meanings. There art material portrays how content matter and characteristic features of the adult and parent contexts reflect in the works of the children. Another clearly noticeable factor in the art material is the impact of time-related traditions and functions on the means of visual expression. Comparing the visual material to the written material reveals variances of meaning and possibilities between these forms of expression. The visual material appears to be related especially to portraying objects, action and usage. Processing through that making of images was noted to bring back memories of concrete structures, details and also emotions. This process offered the child an intensive social connection with the adults. In some cases, with children and adults alike, this project brought forth an ongoing relation to visual expression. During this study I end up changing the concept to ‘home-school collaboration’. This widely used concept guides and outlines the interaction between schools and homes. In order to broaden the field of possibilities, I choose to use the concept ‘school-home interconnection’. This concept forms better grounds for forming varying impressions and practices when building interactive contexts. This concept places the responsibility of bridging the connection-gap in the schools. Through the experiences and innovations of thought gained from these projects, I form a model of pedagogy that embraces the idea of school-home interconnection and builds on the various impres-sions and expressions contained in it. In this model, school makes use of the experiences, thoughts and conceptions from the home environment. Various forms of expression are used to portray and process this information. This joint evaluation and observation evolves thought patterns both in school and at home. Keywords: percieving, visuality, visual culture, art and text, visual expression, art education, growth in interaction, home-school collaboration, school-home interconnection, school-home interaction model.

Snoring and sleep apnea in children

Snoring is a primary and major clinical symptom of upper airway obstruction during sleep. Sleep-disordered breathing ranges from primary snoring to significant partial upper airway obstruction, and obstructive sleep apnea. Adult snoring and obstructive sleep apnea have been extensively studied, whereas less is known about these disorders in children. Snoring and more severe obstructive sleep apnea have been shown to have a harmful effect on the neurobehavioral development of children, but the mechanisms of this effect remains unknown. Furthermore, the correlation of this effect to objective sleep study parameters remains poor. This study evaluated the prevalence of snoring in preschool-aged children in Finland. Host and environmental risk factors, and neurobehavioral and neurocognitive symptoms of children suffering from snoring or obstructive sleep apnea were also investigated. The feasibility of acoustic rhinometry in young children was assessed. The prevalence and risk factors of snoring (I) were evaluated by a questionnaire. The random sample included 2100 children aged 1-6 years living in Helsinki. All 3- to 6-year-old children whose parents reported their child to snore always, often, or sometimes were categorized as snorers, and invited to participate to the clinical study (II-IV). Non-snoring children whose parents were willing to participate in the clinical study were invited to serve as controls. Children underwent a clinical ear-nose-throat examination. Emotional, behavioral, and cognitive performances were evaluated by Child Behavioral Checklist (CBCL), Wechsler Preschool and Primary Scale of Intelligence (WPPSI-R) and NEPSY-A Developmental Neuropsychological Assessment (NEPSY). Nasal volume was measured by acoustic rhinometry, and nasal resistance by rhinomanometry. Lateral and posteroanterior cephalometry were performed. A standard overnight ambulatory polysomnography was performed in the home environment. Twenty-six healthy children were tested in order to assess the feasibility of acoustic rhinometry in young children (V). Snoring was common in children; 6.3% of children snored always or often, whereas 81.3% snored never or occasionally. No differences were apparent between snorers and non-snorers regarding age, or gender. Pediatric snoring was associated with recurrent upper respiratory infections, otitis media, and allergic rhinitis. Exposure to parental tobacco smoke, especially maternal smoking, was more common among snorers. Rhinitis was more common among children who exposured to tobacco smoke. Overnight polysomnography (PSG) was performed on 87 children; 74% showed no signs of significant upper airway obstruction during sleep. Three children had obstructive apnea/hypopnea index (OAHI) greater than 5/h. Age, gender, or a previous adenoidectomy or tonsillectomy did not correlate with OAHI, whereas tonsillar size did correlate with OAHI. Relative body weight and obesity correlated with none of the PSG parameters. In cephalometry, no clear differences or correlations were found in PSG parameters or between snorers and non-snorers. No correlations were observed between acoustic rhinometry, rhinomanometry, and PSG parameters. Psychiatric symptoms were more frequent in the snoring group than in the nonsnoring group. In particular, anxious and depressed symptoms were more prevalent in the snoring group. Snoring children frequently scored lower in language functions. However, PSG parameters correlated poorly with neurocognitive test results in these children. This study and previous studies indicate that snoring without episodes of obstructive apnea or SpO2 desaturations may cause impairment in behavioral and neurocognitive functions. The mechanism of action remains unknown. Exposure to parental tobacco smoke is more common among snorers than non-snorers, emphasizing the importance of a smoke-free environment. Children tolerated acoustic rhinometry measurements well.

Analysis-aware design of embedded systems software

In the past many different methodologies have been devised to support software development and different sets of methodologies have been developed to support the analysis of software artefacts. We have identified this mismatch as one of the causes of the poor reliability of embedded systems software. The issue with software development styles is that they are ``analysis-agnostic.'' They do not try to structure the code in a way that lends itself to analysis. The analysis is usually applied post-mortem after the software was developed and it requires a large amount of effort. The issue with software analysis methodologies is that they do not exploit available information about the system being analyzed.

In this thesis we address the above issues by developing a new methodology, called "analysis-aware" design, that links software development styles with the capabilities of analysis tools. This methodology forms the basis of a framework for interactive software development. The framework consists of an executable specification language and a set of analysis tools based on static analysis, testing, and model checking. The language enforces an analysis-friendly code structure and offers primitives that allow users to implement their own testers and model checkers directly in the language. We introduce a new approach to static analysis that takes advantage of the capabilities of a rule-based engine. We have applied the analysis-aware methodology to the development of a smart home application.

Estudo DFT para a interação das moléculas de CO e NO com perovskitas de LaFePdO3 dopadas com Mn, Co e Ni

Recentemente, vem sendo desenvolvido o uso de catalisadores de metais preciosos suportados por óxidos do tipo perovskita em automóveis. Tais sistemas catalíticos são conhecidos como catalisadores Inteligentes. A tecnologia dos catalisadores inteligentes aponta para um novo futuro na catálise automotiva e surge como um promissor substituinte para os catalisadores convencionais. O entendimento dos principais fatores que levam a auto regeneração destes catalisadores é um passo fundamental no processo de evolução desta tecnologia. O mecanismo de auto regeneração é responsável diretamente pelo aumento considerável do tempo de vida útil destes catalisadores perante aos convencionais. Consequentemente, o seu custo é bem mais baixo comparado ao convencional. Outro fator relevante é a durabilidade estrutural e o grande número de possibilidade de combinações possíveis das perovskita que fazem delas excelentes estruturas para estudo. O objetivo do trabalho é entender o processo auto regenerativo do catalisador automotivo a base de perovskita dopadas com um átomo de cobalto, manganês e níquel e quando expostas a um ambiente com uma molécula de NO e CO , através da análise da interação desses átomos dopantes em relação a estrutura da perovskita e como se comportará o átomo de paládio ao entrar em contato com a molécula de NO e CO

The autobiographical project of Soveida Dosamantes in Face of an angel, by Denise Chávez

O objetivo desta dissertação é investigar o viés coletivo da autobiografia ficcional de Face of an angel, da escritora estadunidense e de origem mexicana Denise Chávez. Desse modo, o trabalho pretende discutir a sociedade chicana descrita sob a ótica da narradora/protagonista, Soveida Dosamantes, investigando desde o processo histórico de que é resultado, passando pela iniquidade entre os papéis desempenhados por homens e mulheres até chegar ao discurso autorreferencial com que a narradora/protagonista representa o ambiente cultural em que se insere. Antes da narrativa propriamente dita, há a árvore genealógica da narradora/protagonista, assinalando que o que vai se descortinar ao longo da leitura é uma saga de família. Assim, Soveida Dosamantes utiliza a sua ambiência doméstica, bem como a comunidade da fictícia cidade de Água Oscura, sua cidade natal, como recorte de uma estrutura social maior. Fazendo uso do discurso autobiográfico, a narradora/protagonista criada por Denise Chávez expõe as mazelas de uma comunidade que, em virtude ser produto do colonialismo e do neocolonialismo, perdeu sua identidade cultural. Em Face of an angel, através do relato em primeira pessoa de sua narradora/protagonista, a autora Denise Chávez reproduz o universo em que nasceu e cresceu. Cedendo a Soveida Dosamantes componentes autobiográficos como complicadas relações familiares, personagens femininas nativas que funcionam como sentinelas de práticas ancestrais que o domínio europeu apagou, personagens masculinos que mascaram sua fragilidade por trás de uma força e de um poder aparentes, Chávez representa em Face of an Angel o microcosmos de uma comunidade que vem, aos poucos, subvertendo o discurso oficial e conquistando o seu terreno no panorama político e social estadunidense

Metodologia de análise do abastecimento de veículos elétricos no contexto das redes inteligentes de energia.

Este trabalho apresenta um modelo de simulação para avaliação da recarga de veículos elétricos em redes de distribuição de energia, com foco na adequação da capacidade dos transformadores. Com base em medições efetuadas, foi possível o tratamento dos dados para a modelagem de curvas de recarga de veículos elétricos e a análise do acréscimo da demanda da recarga em transformadores de distribuição. O modelo de simulação permite avaliar os efeitos das variáveis relacionadas à distância percorrida e ao horário da conexão dos veículos elétricos à rede, tanto de forma determinística quanto de forma aleatória. Estes efeitos foram comparados e permitiram concluir a importância da utilização deste método mais realista para calcular a capacidade dos transformadores, visando suprir esta nova demanda. Além disso, o trabalho apresenta indicadores dos benefícios ambientais e energéticos da penetração dos veículos elétricos no que diz respeito ao gasto com reabastecimento e às emissões evitadas, respectivamente, ao se utilizar veículos elétricos à bateria em substituição aos tradicionais veículos à combustão interna.
