Full Text Available Os jornais dos principais países desenvolvidos vivem uma crise frequentemente atribuída ao desenvolvimento das mídias digitais. Essa situação parece não se reproduzir nas maiores economias emergentes. O presente trabalho sustenta que, embora o surgimento e avanço dessas mídias tenham efetivamente afetado negativamente o desempenho das empresas jornalísticas, a crise em questão é estrutural e suas origens antecedem o surgimento das mídias digitais. A hipótese de que a situação dos países emergentes seja estruturalmente diversa é testada e, acredita-se, refutada por meio de uma analise comparativa da evolução recente do negócio jornal nos EUA e no Brasil.

Multifractal features of EUA and CER futures markets by using multifractal detrended fluctuation analysis based on empirical model decomposition

International Nuclear Information System (INIS)

Cao, Guangxi; Xu, Wei

2016-01-01

Basing on daily price data of carbon emission rights in futures markets of Certified Emission Reduction (CER) and European Union Allowances (EUA), we analyze the multiscale characteristics of the markets by using empirical mode decomposition (EMD) and multifractal detrended fluctuation analysis (MFDFA) based on EMD. The complexity of the daily returns of CER and EUA futures markets changes with multiple time scales and multilayered features. The two markets also exhibit clear multifractal characteristics and long-range correlation. We employ shuffle and surrogate approaches to analyze the origins of multifractality. The long-range correlations and fat-tail distributions significantly contribute to multifractality. Furthermore, we analyze the influence of high returns on multifractality by using threshold method. The multifractality of the two futures markets is related to the presence of high values of returns in the price series.

Full Text Available To compare finish times across WMM races for Boston, London, Berlin, Chicago and New York Marathons.Race times of the top 10 male and 10 female finishers were analyzed from 2005 to 2014 using the high-performance mixed linear model procedure in the Statistical Analysis System. Venue-to-venue comparisons, as well as comparisons between Boston and other WMM races, with and without factors of temperature, humidity and altitude change were examined.Performance from 2005 to 2014 in the WMM races was found to improve at a rate of ~1% each 7 years. Despite its higher variability, comparison between Boston's estimated mean finishing time and all other venues revealed moderate positive differences, indicating the Boston event to be typically slower than other venues.Across the 10-year study period, performance times improved ~1% each 7 years for both genders for the WMM, with the Boston Marathon being slower on average than other WMM venues. Weather rather than course metrics appeared to impact performance times most.

Ensino de BIM em curso de graduação em engenharia civil em uma universidade dos EUA: estudo de caso

Directory of Open Access Journals (Sweden)

Priscilla Elisa de Azevedo Basto

Full Text Available Resumo Com o crescente avanço da tecnologia, os empreendimentos da construção civil se tornam cada vez mais complexos. Como forma de acompanhar esse processo, foi desenvolvido o paradigma denominado de Building Information Modeling (BIM, que se baseia na colaboração entre as equipes para a elaboração de um modelo integrado e 3D da edificação do qual serão retiradas as informações necessárias para a gestão do empreendimento. O BIM vem sendo utilizado por diversas empresas, devido aos benefícios potenciais, entretanto sua difusão continua sendo restrita em razão do fato de ser dominado por pequena quantidade de profissionais. Dessa forma, este trabalho objetiva descrever um método de abordagem do ensino de BIM, permitindo a sua avaliação para potencial difusão e utilização, e demonstrar a importância desse método. Para isso foram realizadas a descrição detalhada e a análise da experiência de ensino do BIM na disciplina de Gerenciamento de Projeto da Construção I, ministrada na Arizona State University (ASU, localizada nos Estados Unidos. Através dos resultados obtidos, constatou-se que a disciplina realiza a abordagem do BIM em conjunto com os outros assuntos, pode ser classificada como de nível intermediário, formando um analista BIM, e se mostrou efetiva em apresentar os principais conceitos e usos do BIM aos discentes.

2016-02-01

The transformation of Boston Harbor from the "dirtiest in America" to a National Park Area is one of the most remarkable estuarine recoveries in the world. A long-term water quality dataset from 1991 to present exists in Boston Harbor due to a $3. 8 billion lawsuit requiring the harbor clean-up. This project uses discrete water sampling and underway transects with a towed vehicle coordinated with Landsat 7 and Landsat 8 to create surface maps of chlorophyll a (Chl a), dissolved organic matter (CDOM and DOC), total suspended solids (TSS), diffuse attenuation coefficient (Kd_490), and photic depth in Boston Harbor. In addition, 3 buoys have been designed, constructed, and deployed in Boston Harbor that measure Chl a and CDOM fluorescence, optical backscatter, salinity, temperature, and meteorological parameters. We are initially using summer and fall of 2015 to develop atmospheric corrections for conditions in Boston Harbor and develop algorithms for Landsat 8 data to estimate in water photic depth, TSS, Chl a, Kd_490, and CDOM. We will report on initial buoy and cruise data and show 2015 Landsat-derived distributions of water quality parameters. It is our hope that once algorithms for present Landsat imagery can be developed, historical maps of water quality can be constructed using in water data back to 1991.

Full Text Available Há 40 anos, em plena Guerra Fria, Robert Bellah concluiu seu célebre artigo sobre a religião civil americana com a seguinte pergunta: como conceber a aplicabilidade legítima dos valores-chave que suportam o imaginário nacional americano para além dos confins territoriais do seu Estado-nação? O presente artigo quer revisitar esta questão criticamente à luz de incursões regulatórias recentes dos EUA sobre o campo da liberdade religiosa no globo. Primeiramente, reviso a história da relação entre secularismo, identidade nacional e cristianismo nos EUA. A seguir, analiso as articulações político-religiosas que dão origem ao International Freedom of Religion Act (IRFA, em 1998. Por fim, tento destacar como este exercício pode fornecer contribuições mais gerais para o estudo da relação entre religião, nacionalismo e poder secular na contemporaeidade, com ênfase na relação entre estes e o princípio de soberania do estado de direito.

Full Text Available Neste artigo, a teoria de cópulas é utilizada para analisar os co-movimentos entre os mercados de capitais do Brasil e dos EUA. Na finalidade de implementação de uma estratégia de alocação de ativos é importante entender os eventos extremos - tanto os positivos (boom como os negativos (crashes - e seus efeitos sobre os mercados. Os índices de mercado usados são o IBOVESPA e o S&P 500 cobrindo o período de 03/2001 a 04/2007. A aderência aos log-retornos das principais cópulas encontradas na literatura financeira é avaliada. Os seguintes critérios foram escolhidos: o Log-likelihod, o critério de informação de Akaike e o critério de informação bayesiano. Os resultados mostram que a cópula de Joe-Clayton simetrizada é a mais adequada para modelar a estrutura de dependência entre os log-retornos do IBOVESPA e os do S&P500. Este trabalho difere de alguns estudos já realizados [e.g. Mendes e Moretti(2005 e Canela e Collazo(2005], pois leva em consideração a modelagem de cópulas dinâmicas introduzida por Patton (2006. Finalmente, através dos índices de dependência caudal ao longo do tempo, pode-se concluir que a ocorrência de eventos extremos negativos (crashes no mercado norte americano tende a afetar mais o mercado brasileiro quando da comparação da ocorrência dos eventos extremos positivos (booms.

1999-12-01

Full Text Available Estudos foram realizados a fim de verificar se crianças escolhiam entre cumprir uma promessa ou dizer a verdade em três dilemas hipotéticos. As escolhas iniciais das crianças eram contra argumentadas pelos entrevistadores adultos a fim de verificar a sugestionabilidade das mesmas. Os resultados dos estudos conduzidos em Recife e Nova Iorque (EUA, mostram que as crianças de 6 a 8 anos foram mais sugestionáveis em alguns dilemas do que as de 10 a 12 anos. As mudanças das escolhas foram mais freqüentes de promessa para verdade do que de verdade para promessa. Foi evidenciada sugestionabilidade significativamente maior nas crianças estadunidenses do que nas brasileiras, particularmente em dois dos dilemas. Estudos repetidos nos EUA e Brasil confirmam esta diferença, que pode ser explicada, em parte, pelas diferentes relações de autoridade observadas nas escolas nas duas culturas. Os dados são discutidos em termos de heteronomia, das características significantes dos dilemas, e das relações de autoridade dentro da cultura.Studies were conducted in which children chose whether to keep a promise or tell the truth in three hypothetical dilemmas. Their initial choices were then counter-probed by adult interviewers to assess their suggestibility. In these studies, conducted in Recife (Brazil and New York City, younger children (6 to 8 were more suggestible on some of the dilemmas than older children (10-12, and shifting was more frequent from promise to truth than from truth to promise. There was significantly greater suggestibility evidenced by the U.S. than the Brazilian children, particularly on two of the dilemmas. Replication studies in the U.S. and Brazil confirm this difference, which may be explained, in part, by different authority relationships observed in schools in the two cultures. Findings are discussed in terms of heteronomy, the significant features of the dilemmas, and authority relations within culture.

Natural gas is the largest source of anthropogenic emissions of methane (CH 4 ) in the United States. To assess pipeline emissions across a major city, we mapped CH 4 leaks across all 785 road miles in the city of Boston using a cavity-ring-down mobile CH 4 analyzer. We identified 3356 CH 4 leaks with concentrations exceeding up to 15 times the global background level. Separately, we measured δ 13 CH 4 isotopic signatures from a subset of these leaks. The δ 13 CH 4 signatures (mean = −42.8‰ ± 1.3‰ s.e.; n = 32) strongly indicate a fossil fuel source rather than a biogenic source for most of the leaks; natural gas sampled across the city had average δ 13 CH 4 values of −36.8‰ (±0.7‰ s.e., n = 10), whereas CH 4 collected from landfill sites, wetlands, and sewer systems had δ 13 CH 4 signatures ∼20‰ lighter (μ = −57.8‰, ±1.6‰ s.e., n = 8). Repairing leaky natural gas distribution systems will reduce greenhouse gas emissions, increase consumer health and safety, and save money. Highlights: ► We mapped 3356 methane leaks in Boston. ► Methane leaks in Boston carry an isotopic signature of pipeline natural gas. ► Replacing failing gas pipelines will provide safety, environmental, and economic benefits. - We identified 3356 methane leaks in Boston, with isotopic characteristics consistent with pipeline natural gas.

The Boston Architectural College's Urban Sustainability initiative is a demonstration project as defined by the National Energy Technology Laboratory. BAC's proposed project with the U.S. Department of Energy - NETL, is a large part of that overall initiative. The BAC's Urban Sustainability Initiative is a multi-part project with several important goals and objectives that will have a significant impact on the surrounding neighborhood including: energy conservation, reduction of storm water runoff, generation of power through alternative energy sources, elimination/reduction of BAC carbon footprint, and to create a vehicle for ongoing public outreach and education. Education and outreach opportunities will serve to add to the already comprehensive Sustainability Design courses offered at BAC relative to energy savings, performance and conservation in building design. At the finish of these essential capital projects there will be technical materials created for the education of the design, sustainability, engineering, community development and historic preservation communities, to inform a new generation of environmentally-minded designers and practitioners, the city of Boston and the general public. The purpose of the initiative, through our green renovations program, is to develop our green alley projects and energy saving renovations to the BAC physical plant, to serve as a working model for energy efficient design in enclosed 19th century and 20th century urban sites and as an educational laboratory for teaching ecological and sustainable technologies to students and the public while creating jobs. The scope of our project as it relates to the BAC and the U.S. Department of Energy- NETL combined efforts includes: Task I of the project is Phase II (Green Alley). Task I encompasses various renovation activities that will demonstrate the effectiveness of permeable paving and ground water recharge systems. It will aid in the reduction of storm water

Objective: To review and summarize effectiveness and method of the Boston's balloon dilation in cardiac achalasia. Methods: The intensified guide wire was inserted into stomach through mouth cavity under TV control. The Boston's balloon was inserted to the cardiac stricture through the guide wire and dilatated with 15% contrast medium with to a maximum diameter for five minutes and then the balloon was dilatated again for 3-5 minutes, all together for 3-4 times. The severe stricture must be pre-dilatated with 20-25 mm diameter balloon. Results: The balloon insertion was technically successful in all 26 patients. The once success of balloon dilation was achieved in 24 patients and twice in other 2. Follow-up time was from 2 weeks to 31 months (mean 10.6 months). Recurrent stenosis had not occurred in all patients. Remission rate of dysphagia was 100%. Esophageal reflux occurred in 3 patients. Conclusions: The Boston's balloon dilatation is simple and effective for treatment of cardiac achalasia. The method sometimes may replace surgical procedure

Gentry, Elisabeth; Poirier, Katie; Wilkinson, Tiana; Nhean, Siphannay; Nyborn, Justin; Siegel, Michael

2011-10-01

We investigated the frequency of alcohol ads at all 113 subway and streetcar stations in Boston and the patterns of community exposure stratified by race, socioeconomic status, and age. We assessed the extent of alcohol advertising at each station in May 2009. We measured gross impressions and gross rating points (GRPs) for the entire Greater Boston population and for Boston public school student commuters. We compared the frequency of alcohol advertising between neighborhoods with differing demographics. For the Greater Boston population, alcohol advertising at subway stations generated 109 GRPs on a typical day. For Boston public school students in grades 5 to 12, alcohol advertising at stations generated 134 GRPs. Advertising at stations in low-poverty neighborhoods generated 14.1 GRPs and at stations in high-poverty areas, 63.6 GRPs. Alcohol ads reach the equivalent of every adult in the Greater Boston region and the equivalent of every 5th- to 12th-grade public school student each day. More alcohol ads were displayed in stations in neighborhoods with high poverty rates than in stations in neighborhoods with low poverty rates.

Foram analisados os potenciais efeitos do NAIS sobre a percepção de risco dos consumidores americanos em relação aos perigos decorrentes do consumo das carnes bovina, suína e de aves e seus derivados. Sistemas de equações de demanda foram estimados, incorporando-se como "proxies" da percepção de risco do consumidor, séries de índices de segurança do alimento, separadamente construídas para cada tipo de carne. Tais séries foram concebidas, somando-se o número de referências nos principais jornais americanos a problemas de segurança da carne. Foi utilizado o melhor modelo estimado, escolhido com base em uma série de testes de especificação, para se construir três cenários, simulando-se os casos em que o NAIS não está implementado; que está implementado apenas para o gado bovino; e que está implementado para suínos e bovinos. Foram utilizadas as diferenças entre as receitas estimadas para cada cenário e para cada tipo de carne, como uma medida do potencial ganho advindo da implementação do NAIS. Foi concluído que os setores da carne bovina e suína poderiam arcar com os custos do NAIS. Esse resultado, contudo, depende de o quanto desses potenciais ganhos chegarão efetivamente aos produtores agrícolas.This article investigates the potential gains to the U.S. meat sector with the implantation of the U.S. National Animal Identification System (NAIS.

Leucemia Mielóide Crônica: novas drogas em desenvolvimento

Directory of Open Access Journals (Sweden)

Cármino A. de Souza

Full Text Available A LMC é um modelo de investigação biológica e clinica que deve ser seguido nesta nova fase da oncologia moderna. A resposta terapêutica ao uso do imatinibe como droga de primeira linha mudou os conceitos e paradigmas e criou uma expectativa que drogas mais potentes possam ser desenvolvidas no futuro. Infelizmente nem todos conseguem atingir essa situação ideal. Por esta razão, Baccarani M sugeriu que a falência de resposta subótima, precaução ou alerta fossem estudadas no sentido de serem desenvolvidas intervenções terapêuticas diferenciadas mais precoces. A resistência ao imatinibe existe e depende de vários mecanismos. Tanto mais tardia a introdução do imatinibe e mais avançada for a fase evolutiva da doença maior a freqüência de resistência. Do ponto de vista biológico, a superexpressão do BCR-ABL, os defeitos genéticos adicionais e as mutações que podem atingir várias regiões da molécula - a alça de fosfato, a alça de ativação, o domínio da quinase são os mais importantes fatores associados à resistência ao imatinibe. Por esta razão, são necessárias outras opções terapêuticas e hoje há o desenvolvimento de um grande número de drogas para um número maior de alvos. Inicialmente temos o dasatinibe, já aprovado nos EUA, na Europa e também no Brasil; o nilotinibe, em fase avançada de estudos clínicos (inclusive de fase III, e também já aprovado para uso nos EUA; o bosutinibe, o INNO - 406 bem como outras drogas que atuam em alvos como as aurora-quinases ou inibidores de histona-deacetilases.

The Boston Strangler was one of the United States' most notorious serial killers, raping and strangling with decorative ligatures thirteen woman in Boston during the early 1960s. Albert DeSalvo, never a suspect in the slayings, confessed in prison (where he was later murdered) to being the Boston Strangler, and the investigation largely ended. Mary Sullivan was the last victim of the Boston Strangler, found sexually assaulted and strangled in her Boston apartment in 1964. Recently, a team of forensic scientists undertook the exhumation and subsequent scientific analysis of Mary Sullivan's remains, in hope of finding consistencies or inconsistencies between DeSalvo's confessed description of the murder and any evidence left behind. Included in these analyses was extensive DNA testing of all UV fluorescent material associated with the body. The large majority of results were negative, however, fluorescent material located on the underwear and entwined in her pubic hair generated two human mitochondrial DNA sequences. Neither of these matched the victim nor members of the forensic team who worked on the evidence. Most importantly, neither DNA sequence could have originated from Albert DeSalvo.

Although corticosteroid use in acute hemorrhagic stroke is not widely adopted, management with intravenous dexamethasone has been standard of care at the University Hospital of Heraklion, Crete with observed outcomes superior to those reported in the literature. To explore this further, we conducted a retrospective, multivariable-adjusted 2-center study. We studied 391 acute hemorrhagic stroke cases admitted to the University Hospital of Heraklion, Crete between January 1997 and July 2010 and compared them with 510 acute hemorrhagic stroke cases admitted to Massachusetts General Hospital, Boston, from January 2003 to September 2009. Of the Cretan cases, 340 received a tapering scheme of intravenous dexamethasone, starting with 16 to 32 mg/day, whereas the Boston patients were managed without steroids. The 2 cohorts had comparable demographics and stroke severity on admission, although anticoagulation was more frequent in Boston. The in-hospital mortality was significantly lower on Crete (23.8%, n=340) than in Boston (38.0%, n=510; Pmortality (Crete: 25.4%, n=307; Boston: 39.4%, n=510; Pmortality: Crete 20.8%; n=259; Boston 37.0%; n=359; Phemorrhages. After adjusting for acute hemorrhagic stroke volume/location, Glasgow Coma Scale, hypertension, diabetes mellitus, smoking, coronary artery disease and statin, antiplatelet, and anticoagulant use, intravenous dexamethasone treatment was associated with better functional outcomes and significantly lower risk of death at 30 days (OR, 0.357; 95% CI, 0.174-0.732). This study suggests that intravenous dexamethasone improves outcome in acute hemorrhagic stroke and supports a randomized clinical trial using this approach.

Mas é fácil definir que Crawford Williamson Long foi o primeiro a utilizar o éter sulfúrico para operar vários pacientes, sem dor, e realizar analgesias obstétricas. A história é uma ponte que liga o passado ao presente e deve ser estudada e entendida desde os seus primeiros pilares. Assim, justifica-se lembrar ou dar a conhecer quem foi Long, um nome certamente pouco conhecido entre nós, e qual a participação dele na descoberta da anestesia. CONTEÚDO: São discorridos porque e como Crawford Williamson Long foi levado a se tornar o primeiro médico a operar sem dor, quatro anos e meio antes de Morton, e o papel que desempenhou numa das maiores descobertas da Medicina. A biografia de Long é narrada, ressaltando-se o seu caráter, a competência, a dedicação, a modéstia, o desprendimento e um certo desapego com relação à conquista da glória. Descrevem-se as circunstâncias que o levaram a não divulgar de imediato sua descoberta. É analisado o envolvimento de Long na discussão pela primazia da descoberta da anestesia e relatado o seu falecimento. As numerosas homenagens recebidas por Long nos EUA e em outros países são citadas. CONCLUSÕES: W. T. G. Morton costuma ser considerado como o autor da descoberta da anestesia geral, sobretudo por ter sido o primeiro a fazer demonstração pública bem-sucedida, em importante hospital de Boston (EUA. Contudo, provou-se que Long foi o primeiro a utilizar a anestesia cirúrgica e é reconhecido em várias regiões de seu país como o pai da anestesia cirúrgica e "o seu descobridor". É necessário, ainda, reverter o fato de ser Long pouco conhecido entre nós e inseri-lo no lugar a que tem direito na história da anestesia geral.JUSTIFICATIVA Y OBJETIVOS: La historia del descubrimiento de la anestesia continúa sin ser completamente aclarada en varios

Threat perception after the Boston Marathon bombings: The effects of personal relevance and conceptual framing.

Science.gov (United States)

Wormwood, Jolie Baumann; Lynn, Spencer K; Feldman Barrett, Lisa; Quigley, Karen S

2016-01-01

We examined how the Boston Marathon bombings affected threat perception in the Boston community. In a threat perception task, participants attempted to "shoot" armed targets and avoid shooting unarmed targets. Participants viewing images of the bombings accompanied by affectively negative music and text (e.g., "Terror Strikes Boston") made more false alarms (i.e., more errors "shooting" unarmed targets) compared to participants viewing the same images accompanied by affectively positive music and text (e.g., "Boston Strong") and participants who did not view bombing images. This difference appears to be driven by decreased sensitivity (i.e., decreased ability to distinguish guns from non-guns) as opposed to a more liberal bias (i.e., favouring the "shoot" response). Additionally, the more strongly affected the participant was by the bombings, the more their sensitivity was reduced in the negatively framed condition, suggesting that this framing was particularly detrimental to the most vulnerable individuals in the affected community.

Full Text Available A presença de sintomas de 'big vein' ou engrossamento das nervuras em alface e a associação do Lettuce big-vein associated virus (LBVaV e Mirafiori lettuce big-vein virus (MLBVV foram verificadas por RT-PCR utilizando-se oligonucleotídeos específicos para ambos os vírus. Foram coletadas 366 plantas sintomáticas nas regiões de Bauru, Campinas e Mogi das Cruzes no estado de São Paulo nos meses de junho e setembro de 2004 e abril e julho de 2005, e 18 plantas assintomáticas na região de Mogi das Cruzes no mês de dezembro de 2004. Infecção mista do LBVaV e MLBVV foi detectada em 76,2% das plantas sintomáticas, em 11,5% somente o MLBVV foi detectado e em 6,6% somente o LBVaV. Nas plantas assintomáticas coletadas em dezembro na região de Mogi das Cruzes, em áreas de alta incidência da doença durante o inverno, foi detectada a presença de MLBVV em 9 amostras e LBVaV em 7 amostras. Quatro dessas amostras apresentaram infecção mista, indicando que o desenvolvimento de sintomas depende de fatores abióticos, como temperatura. A inoculação via extrato vegetal a partir de plantas de alface com infecção mista pelo MLBVV e LBVaV foi realizada a 16°C/ 10°C (dia/noite e fotoperíodo de 11 horas, verificando-se que o MLBVV foi transmitido para Nicotiana tabacum TNN, N. rustica, N. occidentalis, Chenopodium quinoa e para as cultivares de alface Trocadero e White Boston, enquanto o LBVaV foi transmitido apenas para a alface White Boston. Entretanto, nenhuma destas plantas apresentou sintomas da doença, com exceção de C. quinoa que apresentou sintomas de lesões locais. Plantio em solo proveniente de áreas com histórico da doença de Mogi das Cruzes permitiu a transmissão do LBVaV para alface cv. White Boston e do MLBVV para alface cv. Trocadero e White Boston, embora apenas a cv. White Boston tenha apresentado sintomas da doença. Em conjunto, estes resultados demonstram a dificuldade de transmissão de ambos os vírus, mesmo em

We compared the impact of media vs. direct exposure on acute stress response to collective trauma. We conducted an Internet-based survey following the Boston Marathon bombings between April 29 and May 13, 2013, with representative samples of residents from Boston (n = 846), New York City (n = 941), and the remainder of the United States (n = 2,888). Acute stress symptom scores were comparable in Boston and New York [regression coefficient (b) = 0.43; SE = 1.42; 95% confidence interval (CI), -2.36, 3.23], but lower nationwide when compared with Boston (b = -2.21; SE = 1.07; 95% CI, -4.31, -0.12). Adjusting for prebombing mental health (collected prospectively), demographics, and prior collective stress exposure, six or more daily hours of bombing-related media exposure in the week after the bombings was associated with higher acute stress than direct exposure to the bombings (continuous acute stress symptom total: media exposure b = 15.61 vs. direct exposure b = 5.69). Controlling for prospectively collected prebombing television-watching habits did not change the findings. In adjusted models, direct exposure to the 9/11 terrorist attacks and the Sandy Hook School shootings were both significantly associated with bombing-related acute stress; Superstorm Sandy exposure wasn't. Prior exposure to similar and/or violent events may render some individuals vulnerable to the negative effects of collective traumas. Repeatedly engaging with trauma-related media content for several hours daily shortly after collective trauma may prolong acute stress experiences and promote substantial stress-related symptomatology. Mass media may become a conduit that spreads negative consequences of community trauma beyond directly affected communities.

Although the field of crisis risk communication has generated substantial research, the interaction between social determinants, communication processes, and behavioral compliance has been less well studied. With the goal of better understanding these interactions, this report examines how social determinants influenced communications and behavioral compliance during the 2010 Boston, Massachusetts, water crisis. An online survey was conducted to assess Boston residents' knowledge, beliefs, attitudes, mass and interpersonal communication, and preventive behaviors on emergency preparedness topics dealing with the water crisis. Of a total sample of 726 respondents, approximately one-third (n = 267) reported having been affected by the water crisis. Only data from affected participants were analyzed. Following an order to boil water, 87.5% of respondents refrained from drinking unboiled tap water. These behaviors and other cognitive and attitudinal factors, however, were not uniform across population subgroups. All communication and behavioral compliance variables varied across sociodemographic factors. Crisis communication, in conjunction with other public health preparedness fields, is central to reducing the negative impact of sudden hazards. Emergency scenarios such as the Boston water crisis serve as unique opportunities to understand how effectively crisis messages are conveyed to and received by different segments of the population.

The role of repeated exposure to collective trauma in explaining response to subsequent community-wide trauma is poorly understood. We examined the relationship between acute stress response to the 2013 Boston Marathon bombings and prior direct and indirect media-based exposure to three collective traumatic events: the September 11, 2001 (9/11) terrorist attacks, Superstorm Sandy, and the Sandy Hook Elementary School shooting. Representative samples of residents of metropolitan Boston (n = 846) and New York City (n = 941) completed Internet-based surveys shortly after the Boston Marathon bombings. Cumulative direct exposure and indirect exposure to prior community trauma and acute stress symptoms were assessed. Acute stress levels did not differ between Boston and New York metropolitan residents. Cumulative direct and indirect, live-media-based exposure to 9/11, Superstorm Sandy, and the Sandy Hook shooting were positively associated with acute stress responses in the covariate-adjusted model. People who experience multiple community-based traumas may be sensitized to the negative impact of subsequent events, especially in communities previously exposed to similar disasters. © The Author(s) 2015.

Lost and unaccounted natural gas can amount to over 6% of Massachusetts' total annual greenhouse gas inventory (expressed as equivalent CO2 tonnage). An unknown portion of this loss is due to natural gas leaks in pipeline distribution systems. The objective of the Boston Methane Project is to estimate the overall leak rate from natural gas systems in metropolitan Boston, and to compare this flux with fluxes from the other primary methane emissions sources. Companion talks at this meeting describe the atmospheric measurement and modeling framework, and chemical and isotopic tracers that can partition total atmospheric methane flux into natural gas and non-natural gas components. This talk focuses on estimation of surface emissions that inform the atmospheric modeling and partitioning. These surface emissions include over 3,300 pipeline natural gas leaks in Boston. For the state of Massachusetts as a whole, the amount of natural gas reported as lost and unaccounted for by utility companies was greater than estimated landfill emissions by an order of magnitude. Moreover, these landfill emissions were overwhelmingly located outside of metro Boston, while gas leaks are concentrated in exactly the opposite pattern, increasing from suburban Boston toward the urban core. Work is in progress to estimate spatial distribution of methane emissions from wetlands and sewer systems. We conclude with a description of how these spatial data sets will be combined and represented for application in atmospheric modeling.

Full Text Available The 2013 Boston marathon was disrupted by two bombs placed near the finish line. The bombs resulted in three deaths and several hundred injuries. Of lesser concern, in the immediate aftermath, was the fact that nearly 6,000 runners failed to finish the race. We were approached by the marathon's organizers, the Boston Athletic Association (BAA, and asked to recommend a procedure for projecting finish times for the runners who could not complete the race. With assistance from the BAA, we created a dataset consisting of all the runners in the 2013 race who reached the halfway point but failed to finish, as well as all runners from the 2010 and 2011 Boston marathons. The data consist of split times from each of the 5 km sections of the course, as well as the final 2.2 km (from 40 km to the finish. The statistical objective is to predict the missing split times for the runners who failed to finish in 2013. We set this problem in the context of the matrix completion problem, examples of which include imputing missing data in DNA microarray experiments, and the Netflix prize problem. We propose five prediction methods and create a validation dataset to measure their performance by mean squared error and other measures. The best method used local regression based on a K-nearest-neighbors algorithm (KNN method, though several other methods produced results of similar quality. We show how the results were used to create projected times for the 2013 runners and discuss potential for future application of the same methodology. We present the whole project as an example of reproducible research, in that we are able to make the full data and all the algorithms we have used publicly available, which may facilitate future research extending the methods or proposing completely different approaches.

Assessing Climate Vulnerabilities of Food Distribution Center Sites in Greater Boston and Their Regional Implications: Climate Adaptation Planning in Practice

Teferra, A.; Watson, C.; Douglas, E. M.

2016-12-01

The Metro Boston region, an area whose civic leaders have been at the forefront of climate resilience initiatives in recent years, is finalizing a flood vulnerability assessment of food distribution center sites located north of Boston, with the support of the University of Massachusetts Boston and the American Geophysical Union's Thriving Earth Exchange program. The community-scientist collaboration emerged because of the need for more local analyses of the area to inform climate resiliency policy and planning actions for the region. A significant amount of the metro region's food supply passes through two major distribution centers in the cities of Everett and Chelsea, just north of the Mystic River. The Metropolitan Area Planning Council (MAPC), on behalf of the Metro Boston Climate Preparedness Taskforce, is working with Chris Watson and Ellen Douglas of UMass Boston to build on existing analyses of the region's food system and climate vulnerabilities and to develop a report identifying flood risk exposure to the sites. The analysis brings in dynamic modeling techniques that incorporate storm surge and sea level rise projections under different climate scenarios, and aims to align methodologies with those of other regional analyses, such as Climate Ready Boston and the City of Cambridge's Vulnerability Assessment. The study is helping to inform MAPC's and the Metro Boston Climate Preparedness Taskforce's understanding of this critical food distribution infrastructure, illustrate the larger regional implications of climate impacts on food distribution in the Greater Boston area, and guide the development of site-specific strategies for addressing identified vulnerabilities.

Full Text Available When the Arab Spring broke out, the United States was in a quandary over how to handle the crisis in its attempt to balance its moral obligations and ideals without undercutting its strategic interests and those of its close allies. Flaws in US diplomatic approach have contributed to one of the most serious foreign policy crisis for a US administration to date with consequential upheaval and erosion of the US-built balance of power. The reactions and policy responses of the Obama administration highlight the difficulties in grasping with the new reality in the Middle East and in enunciating a policy platform that could combine American interests and values.Quando a Primavera Árabe eclodiu, os Estados Unidos ficaram num dilema sobre como lidar com a crise tentando equilibrar as suas obrigações morais e os ideais sem fragilizar os seus interesses estratégicos e aqueles dos seus aliados mais próximos. A indecisão e as contradições na abordagem diplomática dos EUA contribuíram para avolumar uma das mais graves crises de política externa dos EUA, pondo em perigo a balança de poder que os EUA criaram na região. A reação e a resposta política da administração Obama põe em destaque a dificuldade de Washington em lidar com a nova realidade no Oriente Médio e em enunciar uma plataforma política que possa conciliar os interesses e os valores americanos.

Inquiry-based, hands-on, graduate content courses have been developed specifically for Boston Public School middle school teachers of Earth Science. Earth Science I: Weather and Water and Earth Science II: The Solid Earth--Earth History and Planetary Systems have been taught a total of seven times to over 120 teachers. Several key attributes to these successful courses have been identified, including co-instruction by a university professor and a high school and a middle school teacher that are familiar with the Boston curriculum, use of hands-on activities that are closed related to those used in the Boston curriculum, pre- and post-course local field trips, and identification of key learning objectives for each day. This model of professional development was developed over several years in all disciplines (Earth Science, Physics, Biology, Chemistry) by the Boston Science Partnership (BSP), an NSF-funded Math Science Partnership program. One of the core strategies of the BSP is these Contextualized Content Courses (CCC), graduate level, lab-based courses taught at either UMass Boston or Northeastern University during summer intensive or semester formats. Two of the eleven courses developed under the grant are Earth Science I & II. This presentation shares the model of the CCC, the impact on teacher participants, the value of these courses for the professor, and lessons learned for successful professional development. Findings about the courses’ impact and effectiveness come from our external evaluation by the Program Evaluation Research Group (PERG). The combination of content and modeling good instructional practices have many positive outcomes for teachers, including increased self-efficacy in science understanding and teaching, positive impacts on student achievement, and teacher shifts from more traditional, more lecture-based instructional models to more inquiry approaches. STEM faculty members become involved in science education and learn and practice new

BUSEFL (Boston University Space Environment Forecast Laboratory) is a comprehensive, integrated project to address the issues and implications of space weather forecasting. An important goal of the BUSEFL mission is to serve as a testing ground for space weather algorithms and operational procedures. One such algorithm is the Magnetospheric Specification and Forecast Model (MSFM), which may be implemented in possible future space weather prediction centers. Boston University Student-satellite for Applications and Training (BUSAT), the satellite component of BUSEFL, will incorporate four experiments designed to measure (1) the earth close-quote s magnetic field, (2) distribution of energetic electrons trapped in the earth close-quote s radiation belts, (3) the mass and charge composition of the ion fluxes along the magnetic field lines and (4) the auroral forms at the foot of the field line in the auroral zones. Data from these experiments will be integrated into a ground system to evaluate space weather prediction codes. Data from the BUSEFL mission will be available to the scientific community and the public through media such as the World Wide Web (WWW). copyright 1996 American Institute of Physics

Future Nuisance Flooding at Boston Caused by Astronomical Tides Alone

Science.gov (United States)

Ray, Richard D.; Foster, Grant

2016-01-01

Sea level rise necessarily triggers more occurrences of minor, or nuisance, flooding events along coastlines, a fact well documented in recent studies. At some locations nuisance flooding can be brought about merely by high spring tides, independent of storms, winds, or other atmospheric conditions. Analysis of observed water levels at Boston indicates that tidal flooding began to occur there in 2011 and will become more frequent in subsequent years. A compilation of all predicted nuisance-flooding events, induced by astronomical tides alone, is presented through year 2050. The accuracy of the tide prediction is improved when several unusual properties of Gulf of Maine tides, including secular changes, are properly accounted for. Future mean sea-level rise at Boston cannot be predicted with comparable confidence, so two very different climate scenarios are adopted; both predict a large increase in the frequency and the magnitude of tidal flooding events.

Methane has substantial greenhouse warming potential and is the principle component of natural gas. Fugitive natural gas emissions could be a significant source of methane to the atmosphere. However, the cumulative magnitude of natural gas leaks is not yet well constrained. We used a combination of point source measurements and ambient monitoring to characterize the methane sources in the Boston urban area. We developed distinct fingerprints for natural gas and multiple biogenic methane sources based on hydrocarbon concentration and isotopic composition. We combine these data with periodic measurements of atmospheric methane and ethane concentration to estimate the fractional contribution of natural gas and biogenic methane sources to the cumulative urban methane flux in Boston. These results are used to inform an inverse model of urban methane concentration and emissions.

Tendo como base a Nova Economia Institucional (NEI, o objetivo deste artigo foi entender como os custos de transação podem influenciar um dos principais elementos de escolha da estrutura de governança, a complexidade das relações contratuais, e como esta influência pode variar nos distintos ambientes institucionais. Para isso, estudou-se a relação contratual entre supermercados e fornecedores de produtos (frutas, verduras e legumes - FLV orgânicos e convencionais em dois diferentes ambientes institucionais (Brasil e EUA. Testaram-se as hipóteses propostas neste artigo por meio de 128 entrevistas, as quais foram analisadas por meio dos modelos de equações estruturais, sendo que um mesmo modelo teórico foi estimado para dois grupos (os dois países para comparação de seus coeficientes. Os resultados encontrados mostraram que a influência dos custos de transação na complexidade da relação contratual, afetando assim a escolha entre as estruturas de governança, foi diferente a depender do ambiente institucional considerado. Conclui-se ao final deste trabalho que há evidências empíricas, demonstradas pelos resultados dos modelos de equações estruturais aqui utilizados, de que o ambiente institucional pode alterar as influências sobre a complexidade das relações contratuais e assim na escolha da estrutura de governança a ser utilizada.

To report the outcomes on the Boston Type 1 Keratoprosthesis at our institution. Retrospective analysis case series. We analyzed 54 eyes of 53 patients who previously underwent Boston Type 1 Keratoprosthesis surgery at our institution from July 2006 to March 2011. Preoperative and postoperative parameters were collected and analyzed. Visual acuity and keratoprosthesis stability. Common preoperative diagnoses were penetrating keratoplasty failure in 49 eyes (90.7%), chronic keratitis in 2 eyes (3.7%), ocular cicatricial pemphigoid in 1 eye (1.85%), Stevens Johnson syndrome in 1 eye (1.85%) and corneal vascularization in 1 eye (1.85%). Additionally, 40 eyes (74%) had preoperative glaucoma, and an Ahmed valve was implanted in 55% of them. Preoperative BCVA ranged from 20/200 to light perception. At an average follow-up of 20.15 months ± 12.7 (range, 1-56), postoperative vision improved to ⩾20/200 in 18 eyes (33.3%) and ⩾20/50 in 4 eyes (7.4%). The graft retention was 96%. The Boston Type 1 keratoprosthesis is a valid option for high-risk patients. The design improvements in the Boston keratoprosthesis, as well as the daily implementation of the therapeutic methods, have notably diminished occurrence of the most serious complications, such as corneal necrosis and endophthalmitis. As such, glaucoma and its subsequent complications now stand as the most prevalent prognostic factor in the long term.

Full Text Available Cet article porte sur un processus de gentrification dans un quartier d’une grande agglomération des États-Unis, Boston. Il montre que ce processus n’a pas seulement résulté de l’évolution des forces du marché et du retour des capitaux dans les centres-villes, des politiques de rénovation urbaine et de transformations culturelles. La mobilisation collective des nouveaux propriétaires a eu un impact décisif, via les associations de quartier dans lesquelles ils se sont engagés depuis les années 1960.This article concerns the process of gentrification in a district of a large urban area in the United States, Boston. It shows that this process has resulted not only from the evolution of market forces and the return of wealth to the inner cities, urban renewal policies and cultural transformations. The collective mobilisation of new property owners has also had a decisive impact, via the neighbourhood associations in which they have been involved since the 1960s.

Nesse sentido, torna-se necessária a avaliação do desempenho sob condições contrastantes em disponibilidade hídrica. Neste estudo, avaliou-se o desempenho de 12 e 6 cultivares de alfafa, respectivamente, em dois experimentos instalados em lisímetros no delineamento estatístico de parcelas subdivididas sob irrigação constante e regime de chuvas. Sob condições controladas, a alfafa responde positivamente à irrigação tanto em relação aos caracteres quantitativos quanto qualitativos e dentre os cultivares estudados, os cultivares Crioula Brasileira e Crioula Chilena apresentaram os melhores desempenhos. Na avaliação de seis meses de duração, não houve correlação entre a discriminação isotópica do carbono (DIC, fixação biológica de nitrogênio (FBN, produção de matéria seca (PMS e eficiência do uso da água (EUA. Na avaliação de um ano sob irrigação a DIC correlacionou-se negativamente com PMS (-0,92**, EUA (-0,94** e FBN (-0,79*. A FBN correlacionou-se positivamente com a PMS (0,93** e EUA (0,87*.

2015-10-01

The aim of this study was to evaluate the imaging findings of head and neck injuries in patients from the Boston Marathon bombing. A total of 115 patients from the Boston Marathon bombing presenting to four hospitals who underwent imaging to evaluate for head and neck injuries were included in the study. Twelve patients with positive findings on radiography or cross-sectional imaging were included in the final analysis. The radiographic, computed tomography (CT), and magnetic resonance (MR) imaging features of these patients were evaluated for the presence of shrapnel and morphological abnormality. Head and neck injuries were seen in 12 out of 115 patients presenting to the four hospitals. There were secondary blast injuries to the head and neck in eight patients, indicated by the presence of shrapnel on imaging. In the four patients without shrapnel, there were two with subgaleal hematomas, one with facial contusion and one with mastoid injury. There were two patients with subarachnoid hemorrhage, one with brain contusion, one with cerebral laceration, and one with globe rupture. There was frontal bone, nasal bone, and orbital wall fracture in one patient each. Imaging identified 26 shrapnel fragments, 21 of which were ball bearings. Injuries to the head and neck region identified on imaging from the Boston Marathon bombing were not common. The injuries seen were predominantly secondary blast injuries from shrapnel, and did not result in calvarial penetration of the shrapnel fragments.

Full Text Available Neste artigo se examina a não adequação dos EUA ao parecer da OMC no contencioso do algodão. Argumenta-se que tal atitude é irracional do ponto de vista do Estado unitário e racional, mas que pode ser explicada por meio de uma perspectiva fragmentada do Estado. Assim, embora a administração desejasse a adequação, cotonicultores e congressistas potencializados por instituições políticas constrangeram as mudanças necessárias. Ao final são projetados cenários para a modificação da política de subsídios agrícolas dos EUA.The article examines the non compliance of the United States with the WTO report on the cotton dispute. It is argued that that attitude is not rational from the unitary and rational State point of view, but it can be explained through a fragmented perspective of the State. Thus, although the administration desired to comply, cotton growers and congressists, strengthened by political institutions, constrained the needed changes. In the end, scenarios about possible changes in the U.S. agriculture subsidy policy are projected.

Full Text Available Entre os anos de 1995 e 1998, foram realizadas 112 cirurgias para tratamento da Síndrome do Túnel do Carpo (STC pela técnica de incisão palmar e utilização do retináculo de Paine. Com o objetivo de avaliar os resultados em longo prazo, os pacientes foram convocados. Houve o retorno de 44 pacientes. Deste total, três pacientes, por terem doenças associadas, foram excluídos, resultando, um total de 53 mãos analisadas. Apresentaremos os resultados da avaliação subjetiva, obtidos através da aplicação de um teste de auto-avaliação chamado de questionário de Boston. Este questionário consiste em perguntas que avaliam a gravidade dos sintomas e o estado funcional no momento da aplicação do mesmo. Através da aplicação do referido questionário encontramos um escore de 1,41 ± 0,57 para gravidade dos sintomas e 1,59 ± 0,93 para o estado funcional. Como este questionário não foi aplicado no pré-operatório deste grupo de pacientes analisados, comparou-se a pontuação obtida com as encontradas na literatura pertinente. Os resultados obtidos demonstraram que as pontuações pós-operatórias são similares àquelas existentes na literatura, mesmo sendo referidas a tempos diferentes de seguimento pós-operatórios, concluindo que havendo uma melhora dos sintomas, o questionário de Boston é sensível a esta mudança clínica.Between the years of 1995 and 1998, 112 surgeries were performed for treating Carpal Tunnel Syndrome (CTS using the technique of palmar incision employing the Paine retinaculum. With the objective of analyzing results in the long-term, the patients were called for review. Forty four patients returned. From these, three patients were excluded due to associated diseases, thus resulting in a total of 53 hands assessed. Here we present the results of the subjective evaluation achieved by applying a self-assessment test called Boston questionnaire. This questionnaire consists of questions evaluating symptoms

Following the Boston Marathon attack, the extraordinary interagency manhunt and shelter-in-place made for a truly unprecedented experience for area families. Although research on Boston youth has found robust associations between manhunt-related experiences and post-attack functioning, such work does little to identify the specific needs of a particularly vulnerable population--i.e., children with a relative who participated in the manhunt. Understanding the adjustment of these youth is critical for informing clinical efforts. Survey of Boston-area parents/caretakers (N = 460) reporting on their child's attack/manhunt-related experiences, as well as psychosocial functioning in the first six post-attack months; analyses compared youth with and without a relative in law enforcement or the armed services who participated in the manhunt. The proportion of youth with likely PTSD was 5.7 times higher among youth with relatives in the manhunt than among youth without. After accounting for child demographics, blast exposure, and children's own exposure to manhunt events (e.g., hearing/seeing gunfire/explosions, having officers enter/search home), having a relative in the manhunt significantly predicted child PTSD symptoms, emotional symptoms, and hyperactivity/inattention. Fear during the manhunt that a loved one could be hurt mediated relationships between having a relative in the manhunt and clinical outcomes; living within the zone of greatest manhunt activity did not moderate observed relationships. Children with relatives called upon to participate in the unprecedented interagency manhunt following the Boston Marathon attack carried a particularly heavy mental health burden. Continued research is needed to clarify the clinical needs of youth with relatives in high-risk occupations. © 2014 Wiley Periodicals, Inc.

Airline deregulation in the United States of America = Desregulamentação aérea nos Estados Unidos

Full Text Available Este artigo apresenta uma análise detalhada sobre a regulamentação e desregulamentação da indústria aeroviária nos Estados Unidos da América. Dado o rápido crescimento tanto em tamanho quanto em influência das companhias aéreas nos EUA, o governo federal estabeleceu leis e regulamentações para posicionar a indústria no que se acreditava ser a direção correta. A ausência de um profundo entendimento das particularidades da indústria aeroviária resultou em uma crescente insatisfação entre as companhias aéreas. A desregulamentação veio como uma solução para muitos problemas, mas também tem sido considerada como uma maldição tanto para companhias aéreas como para passageiros. Através de uma revisão da literatura, esse artigo discute as reais consequências da desregulamentação aérea nos EUA e como isso tem influenciado a maneira como as pessoas voam na America

The energy efficiency partnership - Kraft General Foods and Boston Edison Company

International Nuclear Information System (INIS)

Crowley, J.C.; Donoghue, J.P.

1993-01-01

During the past twenty years, inordinate shifts in the supply and demand of energy have forced both electric utility companies and their customers to investigate new and innovative ways to satisfy the ever increasing demand for electricity. The Energy Efficiency Partnership, developed between Kraft General Foods and Boston Edison Company, presents an exemplary study of how two corporate giants creatively solved the problem of uncontrolled energy costs and its positive effect on the overall operations of Kraft General Foods, Framingham. But the Energy Efficiency Partnership did more than reduce energy costs, it provided benefits to all parties on the playing field. To understand its significance, a review of the partnership's history is paramount. The first official announcement of the Energy Efficiency Partnership was made on April 9, 1990. Framingham, MA, The Commonwealth of Massachusetts Kraft General Foods Framingham, and Boston Edison Company have joined forces in a $3.6 million dollar energy partnership that will help keep 250 industrial jobs in Massachusetts and could lead to the future expansion of the international food company's Framingham facility

Full Text Available RESUMO Em contraste com vários outros estados brasileiros, apenas recentemente o Mato Grosso do Sul iniciou o inventário organizado de sua avifauna. Relacionamos 630 espécies de aves para o Mato Grosso do Sul, pertencentes a 26 ordens e 74 famílias, que corresponde a 34% da avifauna ocorrente no Brasil. Cerca de 90% dessas espécies apresentam registros comprobatórios de ocorrência no estado conforme as normas propostas pelo CBRO. As demais ainda aguardam documentação comprobatória adequada. Quarenta e cinco espécies foram incluídas na lista terciária por apresentarem problemas de documentação comprobatória devido à ausência de circunstanciação e distribuição incompatível. A grande diversidade de fitofisionomias e paisagens sob influência dos biomas Cerrado, Pantanal, Chaco, Bosques Chiquitanos e Mata Atlântica são responsáveis em parte, pela diversidade de espécies ocorrentes no Mato Grosso do Sul. No entanto, várias dessas fitofisionomias e paisagens já foram suprimidas e/ou alteradas pela pecuária e principalmente monoculturas ( Pinus, Eucalyptus e cana-de-açúcar. Trinta e sete espécies de aves ocorrentes no estado encontram-se presentes em listas de espécies ameaçadas de extinção em âmbito global e/ou nacional. Ainda existem grandes lacunas de conhecimento sobre a avifauna sul-matogrossense, notadamente no Pantanal do Paiaguás e em regiões limítrofes com o estado de Goiás e países como Paraguai (Chaco e a Bolívia (Bosques Chiquitanos. Instituições como Embrapa Pantanal e Universidade Federal de Mato Grosso do Sul, bem como o trabalho de consultores ambientais e observadores de aves foram relevantes no avanço do conhecimento sobre a avifauna no estado.

Methane emissions from the natural gas supply chain must be quantified to assess environmental impacts of natural gas and to develop emission reduction strategies. We report natural gas emission rates for one year in the urban region of Boston, MA, using an atmospheric measurement and modeling framework. Continuous methane observations from four stations are combined with a high-resolution transport model to quantify the regional average emission rate, 20.6 ± 1.7 (95 % CI) g CH4 m-2 yr-1. Simultaneous observations of atmospheric ethane, compared with the ethane to methane ratio in pipeline gas, demonstrate that natural gas accounted for 58 - 100 % of methane emissions, depending on season. Using government statistics and geospatial data on energy consumption, we estimate the fractional loss rate to the atmosphere from all downstream components of the natural gas system, including transmission, distribution, and end-use, was 2.9 ± 0.3 % in the Boston urban region, compared to 1.1 % inferred by the Massachusetts greenhouse gas inventory.

The Boston Area Community Health (BACH) Survey is a community-based, random sample, epidemiologic cohort of n = 5502 Boston (MA) residents. The baseline BACH Survey (2002-05) was designed to explore the mechanisms conferring increased health risks on minority populations with a particular focus on urologic signs/symptoms and type 2 diabetes. To this end, the cohort was designed to include adequate numbers of US racial/ethnic minorities (Black, Hispanic, White), both men and women, across a broad age of distribution. Follow-up surveys were conducted ∼5 (BACH II, 2008) and 7 (BACH III, 2010) years later, which allows for both within- and between-person comparisons over time. The BACH Survey's measures were designed to cover the following seven broad categories: socio-demographics, health care access/utilization, lifestyles, psychosocial factors, health status, physical measures and biochemical parameters. The breadth of measures has allowed BACH researchers to identify disparities and quantify contributions to social disparities in a number of health conditions including urologic conditions (e.g. nocturia, lower urinary tract symptoms, prostatitis), type 2 diabetes, obesity, bone mineral content and density, and physical function. BACH I data are available through the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) Central Repositories (www.niddkrepository.org).

A new spin on research translation: the Boston Consensus Conference on Human Biomonitoring.

2009-04-01

Translating research to make it more understandable and effective (research translation) has been declared a priority in environmental health but does not always include communication to the public or residents of communities affected by environmental hazards. Their unique perspectives are also commonly missing from discussions about science and technology policy. The consensus conference process, developed in Denmark, offers a way to address this gap. The Boston Consensus Conference on Human Biomonitoring, held in Boston, Massachusetts, in the fall of 2006, was designed to educate and elicit input from 15 Boston-area residents on the scientifically complex topic of human biomonitoring for environmental chemicals. This lay panel considered the many ethical, legal, and scientific issues surrounding biomonitoring and prepared a report expressing their views. The lay panel's findings provide a distinct and important voice on the expanding use of biomonitoring. In some cases, such as a call for opt-in reporting of biomonitoring results to study participants, they mirror recommendations raised elsewhere. Other conclusions have not been heard previously, including the recommendation that an individual's results should be statutorily exempted from the medical record unless permission is granted, and the opportunity to use biomonitoring data to stimulate green chemistry. The consensus conference model addresses both aspects of a broader conception of research translation: engaging the public in scientific questions, and bringing their unique perspectives to bear on public health research, practice, and policy. In this specific application, a lay panel's recommendations on biomonitoring surveillance, communication, and ethics have practical implications for the conduct of biomonitoring studies and surveillance programs.

Surface wave site characterization at 27 locations near Boston, Massachusetts, including 2 strong-motion stations

2014-01-01

The geotechnical properties of the soils in and around Boston, Massachusetts, have been extensively studied. This is partly due to the importance of the Boston Blue Clay and the extent of landfill in the Boston area. Although New England is not a region that is typically associated with seismic hazards, there have been several historical earthquakes that have caused significant ground shaking (for example, see Street and Lacroix, 1979; Ebel, 1996; Ebel, 2006). The possibility of strong ground shaking, along with heightened vulnerability from unreinforced masonry buildings, motivates further investigation of seismic hazards throughout New England. Important studies that are pertinent to seismic hazards in New England include source-parameter studies (Somerville and others, 1987; Boore and others, 2010), wave-propagation studies (Frankel, 1991; Viegas and others, 2010), empirical ground-motion prediction equations (GMPE) for computing ground-motion intensity (Tavakoli and Pezeshk, 2005; Atkinson and Boore, 2006), site-response studies (Hayles and others, 2001; Ebel and Kim, 2006), and liquefaction studies (Brankman and Baise, 2008). The shear-wave velocity (VS) profiles collected for this report are pertinent to the GMPE, site response, and liquefaction aspects of seismic hazards in the greater Boston area. Besides the application of these data for the Boston region, the data may be applicable throughout New England, through correlations with geologic units (similar to Ebel and Kim, 2006) or correlations with topographic slope (Wald and Allen, 2007), because few VS measurements are available in stable tectonic regions.Ebel and Hart (2001) used felt earthquake reports to infer amplification patterns throughout the greater Boston region and noted spatial correspondence with the dominant period and amplification factors obtained from ambient noise (horizontal-to-vertical ratios) by Kummer (1998). Britton (2003) compiled geotechnical borings in the area and produced a

The adsorption behaviors of ammonium ions from aqueous solution by a novel bioadsorbent,the Boston ivy (Parthenocissus tricuspidata) leaf powder (BPTL) were investigated.The SEM images and FT-IR spectra were used to characterize BPTL.The mathematical models were used to analyze the adsorption kinetics and isotherms.The optimum pH range for ammonium adsorption by BPTL was found to be 5-10.The adsorption reached equilibrium at 14 hr,and the kinetic data were well fitted by the Logistic model.The intraparticle diffusion was the main rate-controlling step of the adsorption process.The high temperature was favorableto the ammonium adsorption by BPTL,indicating that the adsorption was endothermic.The adsorption equilibrium fitted well to both the Langrnuir model and Freundlich model,and the maximum monolayer adsorption capacities calculated from Langmuir model were 3.37,5.28 and 6.59 mg N/g at 15,25 and 35℃,respectively,which were comparable to those by reported minerals.Both the separation factor (RL) from the Langmuir model and Freundlich exponent (n) suggested that the ammonium adsorption by BPTL was favorable.Therefore,the Boston ivy leaf powder could be considered a novel bioadsorbent for ammonium removal from aqueous solution.

Bluff evolution along coastal drumlins: Boston Harbor Islands, Massachusetts

Science.gov (United States)

Himmelstoss, E.A.; FitzGerald, D.M.; Rosen, P.S.; Allen, J.R.

A series of partially drowned drumlins forms the backbone of the inner islands within Boston Harbor. The shoreline of these rounded glacial deposits is composed of actively retreating bluffs formed by continual wave attack. Comparisons of bluffs reveal variability in their height and lateral extent, as well as in the dominant mechanism causing their retreat. Two processes are responsible for bluff erosion and yield distinct bluff morphologies: (1) wave attack undercuts the bluff and causes episodic slumping, yielding planar bluff slopes, and (2) subaerial processes such as rainfall create irregular slopes characterized by rills and gullies. We propose a model of drumlin bluff evolution that is based on processes of erosion and physical characteristics such as bluff height, slope morphology, and the orientation of the bluff with respect to the long axis of the drumlin and its topographic crest. The four phases of drumlin bluff evolution consist of (1) initial formation of bluff, with retreat dominated by wave notching and slumping processes; (2) rill and gully development as bluff heights exceed 10 m and slumped sediment at bluff base inhibits wave attack; (3) return of wave notching and slumping as bluff heights decrease; and (4) final development of boulder retreat lag as last remnants of drumlin are eroded by wave action. These phases capture the important physical processes of drumlin evolution in Boston Harbor and could apply to other eroding coastal drumlin deposits.

To determine the cumulative worldwide incidence of infectious endophthalmitis and associated vision loss after Boston keratoprosthesis (B-KPro) Type I/II implantation and to propose both safe and inexpensive prophylactic antibiotic regimens. Two retrospective methods were used to determine the incidence, visual outcomes and aetiologies of infectious endophthalmitis associated with the B-KPro divided per decade: (i) systematic review of the literature from 1990 through January 2013 and (ii) a surveillance survey sent to all surgeons who implanted B-KPros through 2010 with 1-year minimum follow-up. In addition, a single-Boston surgeon 20-year experience was examined. From 1990 through 2010, there were 4729 B-KPros implanted worldwide by 209 U.S. surgeons and 159 international surgeons. The endophthalmitis cumulative mean incidence declined from 12% during its first decade of use to about 3% during its second decade in the Unites States and about 5% internationally during the second decade. There remains a large incidence range both in the United States (1-12.5%) and internationally (up to 17%). Poor compliance with daily topical antibiotics is an important risk factor. While Gram-positive organisms remained dominant, fungal infections emerged during the second decade. Daily prophylactic topical antibiotics have dramatically reduced the endophthalmitis incidence. Although Gram-positive organisms are the most common aetiology, antimicrobials must be inclusive of Gram-negative organisms. Selection of prophylactic regimens should be tailored to local antibiotic susceptibility patterns, be cost-effective, and should not promote the emergence of antimicrobial resistance. An example of a broad-spectrum, low-cost prophylactic option for non-autoimmune patients includes trimethoprim/polymyxinB once daily. © 2014 Acta Ophthalmologica Scandinavica Foundation.

Avalonian (Pan-African) mylonitic deformation west of Boston, U.S.A.

Science.gov (United States)

Rast, N.; Skehan, J. W.

1995-07-01

West of Boston, Mass., Castle and others (1976) recognized an up to 5km wide, possibly folded, NE-SW trending Burlington Mylonite Zone. We have extended mapping south into Natick and Framington quadrangles, and supplemented it by fixing local directions of tectonic motion, which are more variable than reported by Goldstein (1989). In Natick the mylonite zone is partly migmatized and converted into blastomylonites, forming the lithodemic Rice Gneiss and is intersected by the Dedham Granite dated ca 630 Ma. The granite also invades deformed, folded, and commonly mylonitized Westboro Quartzite. Thus mylonitization, folding, and formation of migmatitic blastomylonites are all earlier than ca 630 Ma, and can collectively be attributed to the main phase of the Avalonian orogeny that in Africa is referred to as the Pan-African I. The sense of movements in the Rice Gneiss is generally sinistral strike-slip with a NE-SW trend of foliation. Other local mylonites have more variable directions of motion. A narrower E-W zone of mylonitization has been recognized by Grimes (M.S. thesis 1993, Boston College) and named the Nobscot Shear Zone. It affects the Milford Granite, also about 630 Ma in age, while similar but narrow shear zones affect other local granites including the Dedham. These zones, dipping steeply north and including the Nobscot, are less intensely mylonitized and are not associated with migmatites. Their age is not known, but since they affect only Precambrian rocks, they are assumed to be late Proterozoic. We attribute these zones to the second stage of the Avalonian or the Pan-African II. The older rocks west of Boston are widely affected by numerous brittle faults. These are all of unknown age, but probably Phanerozoic. The most significant brittle fault in the Burlington area is the mid to late Paleozoic Bloody Bluff Fault. We do not associate large scale mylonitization with that fault, because the mylonites are commonly cut by undeformed or little deformed

MÉTODOS: Três pacientes pediátricos portadores da síndrome da imunodeficiência humana (AIDS, em tratamento com HAART, foram submetidos a exame oftalmológico em um centro universitário de referência - UNIFESP. RESULTADOS: Os três pacientes do sexo masculino apresentavam média de idade de seis anos (variando entre 10 meses e 13 anos e todos pertenciam à classificação C3 (CDC - Atlanta - EUA 1994. A média obtida entre a contagem de linfócitos CD4+ dos três casos foi de 67 cel/mm³ (variando entre 43 - 98 cel/mm³; e a média da carga viral foi de 190.000 cópias/ml (variando entre 53.600 - 460.000 cópias/ml. Os três pacientes desenvolveram resistência ao uso dos antiretrovirais análogos de nucleosídeos inibidores da transcriptase reversa e aos inibidores de protease (HAART, e em todos os casos foram utilizados antivirais específicos para o tratamento da retinite pelo CMV sem sucesso. CONCLUSÕES: Os benefícios obtidos desde a introdução da era HAART são, sem dúvida, sem precedentes dentro do quadro evolutivo da AIDS. O início da falência terapêutica observado com relação às drogas do HAART tem colaborado de maneira decisiva para o surgimento de casos de retinite pelo CMV tão agressivos quanto os observados na era pré-HAART.

A Secondary Spatial Analysis of Gun Violence near Boston Schools: a Public Health Approach.

Science.gov (United States)

Barboza, Gia

2018-04-11

School neighborhood violence continues to be a major public health problem among urban students. A large body of research addresses violence at school; however, fewer studies have explored concentrations of violence in areas proximal to schools. This study aimed to quantify the concentration of shootings near schools to elucidate the place-based dynamics that may be focal points for violence prevention. Geocoded databases of shooting and school locations were used to examine locational patterns of firearm shootings and elementary, middle, and high schools in Boston, Massachusetts. Analyses utilized spatial statistics for point pattern data including distance matrix and K function methodology to quantify the degree of spatial dependence of shootings around schools. Results suggested that between 2012 and 2015, there were 678 shooting incidents in Boston; the average density was 5.1 per square kilometer. The nearest neighbor index (NNI = 0.335 km, p shooting incidents indicative of a spatially non-random process. The mean and median distance from any school to the nearest shooting location was 0.35 and 0.33 km, respectively. A majority (56%, 74/133) of schools in Boston had at least one shooting incident within 400 m, a distance that would take about 5 min to walk if traveling by foot. The bivariate K function indicated that a significantly greater number of shootings were clustered within short distances from schools than would be expected under a null hypothesis of no spatial dependence. Implications for students attending schools in racially homogenous neighborhoods across all income levels are discussed.

The aim of this study is to describe the imaging findings of abdominal and pelvic injuries in victims of the Boston Marathon bombing. A retrospective review of 87 patients following the Boston Marathon bombing was performed to evaluate for abdominal and pelvic injuries on plain radiography or CT scans of the abdomen and pelvis. Imaging exams were evaluated for shrapnel, soft tissue injury, visceral damage, vascular disruption, and fractures. The injuries were classified as primary, secondary, tertiary, and quaternary blast injuries. Eleven of the 87 patients had positive findings in the abdomen or pelvis (M:F = 7:4, average age 34.6 years). There were 22 ball bearings, two nails, one screw, and two irregular metal fragments in the 11 patients with secondary blast (shrapnel) injuries. There was no peritoneal penetration or visceral injury seen in any of the patients. One patient had multiple transverse process fractures, representing tertiary blast injury. All but one patient had superficial penetrating abdominal or pelvic injuries secondary to shrapnel. There were no cases of bowel or solid visceral organ injuries due to the lack of peritoneal violation from the relatively low-powered explosions. Absence of peritoneal penetration by shrapnel indicates no need for laparotomy following low-powered explosions.

Mapping carbon storage in urban trees with multi-source remote sensing data: Relationships between biomass, land use, and demographics in Boston neighborhoods

Raciti, Steve M.; Hutyra, Lucy R.; Newell, Jared D.

2014-01-01

High resolution maps of urban vegetation and biomass are powerful tools for policy-makers and community groups seeking to reduce rates of urban runoff, moderate urban heat island effects, and mitigate the effects of greenhouse gas emissions. We developed a very high resolution map of urban tree biomass, assessed the scale sensitivities in biomass estimation, compared our results with lower resolution estimates, and explored the demographic relationships in biomass distribution across the City of Boston. We integrated remote sensing data (including LiDAR-based tree height estimates) and field-based observations to map canopy cover and aboveground tree carbon storage at ∼ 1 m spatial scale. Mean tree canopy cover was estimated to be 25.5 ± 1.5% and carbon storage was 355 Gg (28.8 Mg C ha −1 ) for the City of Boston. Tree biomass was highest in forest patches (110.7 Mg C ha −1 ), but residential (32.8 Mg C ha −1 ) and developed open (23.5 Mg C ha −1 ) land uses also contained relatively high carbon stocks. In contrast with previous studies, we did not find significant correlations between tree biomass and the demographic characteristics of Boston neighborhoods, including income, education, race, or population density. The proportion of households that rent was negatively correlated with urban tree biomass (R 2 = 0.26, p = 0.04) and correlated with Priority Planting Index values (R 2 = 0.55, p = 0.001), potentially reflecting differences in land management among rented and owner-occupied residential properties. We compared our very high resolution biomass map to lower resolution biomass products from other sources and found that those products consistently underestimated biomass within urban areas. This underestimation became more severe as spatial resolution decreased. This research demonstrates that 1) urban areas contain considerable tree carbon stocks; 2) canopy cover and biomass may not be related to the demographic characteristics of Boston

The aim of this study is to describe the radiologic imaging findings of primary, secondary, tertiary, and quaternary blast injuries in patients injured in the Boston Marathon bombing on April 15, 2013. A total of 43 patients presenting to three acute care hospitals and undergoing radiologic investigation within 7 hours of the time of the bombing on April 15, 2013, were included in this study. The radiographic and CT features of these patients were evaluated for imaging findings consistent with primary, secondary, tertiary, and quaternary blast injury. There were no pulmonary or gastrointestinal manifestations of the primary blast wave on imaging. Secondary blast injuries identified on imaging included a total of 189 shrapnel fragments identified in 32 of the 43 patients. The shrapnel was identified most often in the soft tissues of the leg (36.5%), thigh (31.2%), and pelvis (13.2%). Imaging identified 125 ball bearings, 10 nails, one screw, 44 metal fragments, and nine other (gravel, glass, etc.) foreign bodies. Injuries from the Boston Marathon bombing were predominantly from the secondary blast wave and resulted in traumatic injuries predominantly of the lower extremities. The most common shrapnel found on radiologic evaluation was the ball bearing.

Louis, David N; O'Brien, Michael J; Young, Robert H

2016-09-01

During most of the nineteenth century, the discipline of pathology in Boston made substantial strides as a result of physicians and surgeons who practiced pathology on a part-time basis. The present essay tells the subsequent story, beginning in 1892, when full-time pathologists begin to staff the medical schools and hospitals of Boston. Three individuals from this era deserve special mention: William T Councilman, Frank Burr Mallory and James Homer Wright, with Councilman remembered primarily as a visionary and teacher, Mallory as a trainer of many pathologists, and Wright as a scientist. Together with S Burt Wolbach in the early-to-mid-twentieth century, these pathologists went on to train the next generation of pathologists-a generation that then populated the various hospitals that were developed in Boston in the early 1900s. This group of seminal pathologists in turn formed the diagnostically strong, academically productive, pathology departments that grew in Boston over the remainder of the twentieth century.

Background Homeless persons experience excess mortality, but U.S.-based studies on this topic are outdated or lack information about causes of death. No studies have examined shifts in causes of death for this population over time. Methods We assessed all-cause and cause-specific mortality rates in a cohort of 28,033 adults aged 18 years or older who were seen at Boston Health Care for the Homeless Program between January 1, 2003, and December 31, 2008. Deaths were identified through probabilistic linkage to the Massachusetts death occurrence files. We compared mortality rates in this cohort to rates in the 2003–08 Massachusetts population and a 1988–93 cohort of homeless adults in Boston using standardized rate ratios with 95% confidence intervals. Results 1,302 deaths occurred during 90,450 person-years of observation. Drug overdose (n=219), cancer (n=206), and heart disease (n=203) were the major causes of death. Drug overdose accounted for one-third of deaths among adults homeless adults in Boston remains high and unchanged since 1988–93 despite a major interim expansion in clinical services. Drug overdose has replaced HIV as the emerging epidemic. Interventions to reduce mortality in this population should include behavioral health integration into primary medical care, public health initiatives to prevent and reverse drug overdose, and social policy measures to end homelessness.

Clougherty Jane E

2006-05-01

Full Text Available Abstract Background The Democratic National Convention (DNC in Boston, Massachusetts in 2004 provided an opportunity to evaluate the impacts of a localized and short-term but potentially significant change in traffic patterns on air quality, and to determine the optimal monitoring approach to address events of this nature. It was anticipated that the road closures associated with the DNC would both influence the overall air pollution level and the distribution of concentrations across the city, through shifts in traffic patterns. Methods To capture these effects, we placed passive nitrogen dioxide badges at 40 sites around metropolitan Boston before, during, and after the DNC, with the goal of capturing the array of hypothesized impacts. In addition, we continuously measured elemental carbon at three sites, and gathered continuous air pollution data from US EPA fixed-site monitors and traffic count data from the Massachusetts Highway Department. Results There were significant reductions in traffic volume on the highway with closures north of Boston, with relatively little change along other highways, indicating a more isolated traffic reduction rather than an across-the-board decrease. For our nitrogen dioxide samples, while there was a relatively small change in mean concentrations, there was significant heterogeneity across sites, which corresponded with our a priori classifications of road segments. The median ratio of nitrogen dioxide concentrations during the DNC relative to non-DNC sampling periods was 0.58 at sites with hypothesized traffic reductions, versus 0.88 for sites with no changes hypothesized and 1.15 for sites with hypothesized traffic increases. Continuous monitors measured slightly lower concentrations of elemental carbon and nitrogen dioxide during road closure periods at monitors proximate to closed highway segments, but not for PM2.5 or further from major highways. Conclusion We conclude that there was a small but

Métodos: revisão bibliográfica utilizando banco de dados Medline, selecionando-se aqueles com informações atuais e relevantes. Resultados:mesmo assumindo que a notificação do erro médico não ocorre em um grande número de eventos, é importante notar que sua incidência é muito maior do que julgamos. Só nos EUA, cerca de um milhão de pacientes por ano são vítimas de erros médicos e eventos adversos com drogas. Segundo recente metanálise, esta é, hoje, a quarta causa de morte nos EUA. Em unidades de terapia intensiva neonatal e pediátrica, nas quais é grande a complexidade e a freqüência de procedimentos, a ocorrência de erros é maior. Estima-se que quinze por cento das internações em unidades de terapia intensiva neonatal sejam acompanhadas de erro médico. A maioria destes erros acontece durante o período noturno, e envolve administração incorreta de droga (35% e erro na interpretação da prescrição (26%.

Full Text Available Resumo Este trabalho investiga o comportamento dos bancos centrais (BCs dos EUA e do Brasil frente à recente crise financeira global. O artigo avalia a atuação das autoridades monetárias por meio de uma leitura sistemática das atas dos respectivos comitês de política monetária entre 2004 e 2011. Procura também identificar conceitos necessários para uma correta leitura e reconhecimento da conjuntura macroeconômica e logo uma possível antecipação ou reação adequada à eclosão da crise. Em ambos os casos os BCs não parecem ter sido capazes de diagnosticar corretamente a evolução da conjuntura macroeconômica, principalmente em termos de detectar a bolha no setor imobiliário dos EUA e se antecipar ao estouro da mesma quando esta adquiriu proporções preocupantes. Quando os mercados financeiros entraram em pânico, os BCs tiveram de reagir pragmaticamente de reagir, mas de forma desorganizada, emergencial e, possivelmente, despreparada, em função da complexidade dos sistemas monetário e financeiro e provavelmente dos respectivos interesses financeiros envolvidos. Finalmente, argumenta-se também que parte desta incapacidade de antecipação pode derivar, entre outros, dos modelos macroeconômicos convencionais empregados pelos BCs e de uma confiança absoluta na hipótese dos mercados eficientes.

Full Text Available O objetivo do presente trabalho foi comparar e analisar os requisitos necessários para registro e as ações de tecnovigilância para implantes dentários nos EUA, na União Europeia e no Brasil. Após análise da literatura e das principais normas em vigor, observou-se a preocupação com o controle de riscos e a prevenção de falhas no uso dos implantes dentários. Nos EUA, o sistema de registro e tecnovigilância é centralizado e se verificam problemas de subnotificação e falhas na análise dos relatórios de notificação, bem como um intervalo de tempo longo entre a identificação dos problemas e a ação devido à extensão do processo administrativo. Na União Europeia, os poucos estudos identificados sugerem que o sistema regulatório oferece riscos aos pacientes devido à ausência de transparência entre os Órgãos Notificadores e à dificuldade em se articular a tecnovigilância entre os países. No Brasil, a tecnovigilância é centralizada, porém ainda é incipiente. O envelhecimento da população promove forte demanda por reabilitação oral dos pacientes, sobretudo os carentes, prevista no programa Brasil Sorridente. A demanda pelo serviço oferece uma oportunidade de expansão do mercado, mas detecta-se risco de entrada de produtos de baixa qualidade. Neste contexto, o aprimoramento das atividades de tecnovigilância de implantes dentários é necessário. -------------------------------------------------------------------------------------------- This study compared and analyzed, after reviewing the literature and the main legal regulations, the requirements for registration and the post-marketing surveillance activities of dental implants in the USA, the European Union and in Brazil.

Summary Background The Boston Area Travel Medicine Network surveyed travelers on travel-related health problems. Methods Travelers were recruited 2009–2011 during pre-travel consultation at three clinics. The investigation included pre-travel data, weekly during-travel diaries, and a post-travel questionnaire. We analyzed demographics, trip characteristics, health problems experienced, and assessed the relationship between influenza vaccination, influenza prevention advice, and respiratory symptoms. Results Of 987 enrolled travelers, 628 (64%) completed all surveys, of which 400 (64%) reported health problems during and/or after travel; median trip duration was 12 days. Diarrhea affected the most people during travel (172) while runny/stuffy nose affected the most people after travel (95). Of those with health problems during travel, 25% stopped or altered plans; 1% were hospitalized. After travel, 21% stopped planned activities, 23% sought physician or other health advice; one traveler was hospitalized. Travelers who received influenza vaccination and influenza prevention advice had lower rates of respiratory symptoms than those that received influenza prevention advice alone (18% vs 28%, P = 0.03). Conclusions A large proportion of Boston-area travelers reported health problems despite pre-travel consultation, resulting in inconveniences. The combination of influenza prevention advice and influenza immunization was associated with fewer respiratory symptoms than those who received influenza prevention advice alone. PMID:27687076

Half the global population lives within 60 km of the ocean, profoundly influencing environmental quality and services to local communities. Adoption of marine science curricula creates opportunities for educators and scientists to engage and entrain K-12 students as ocean stewards. In particular, boat-based science activities facilitate hands-on inquiry. These activities reinforce key science concepts while creating a tangible connection to our shared coastal "backyard." A collaboration between Zephyr Education Foundation, the New England Aquarium, the University of Massachusetts Boston and Woods Hole Oceanographic Institution has taken >500 Boston, MA area students from 26 public schools on boat-based education trips in Boston Harbor. Marine science and technology professionals and educators facilitate participatory activities using modern marine technology aboard a research vessel. Trips are funded at no cost to participants by a grant from the Richard Lounsbery Foundation; cost-free outings are essential for participation from underserved public school districts. Participants perceived three important outcomes of their outings: the trips 1) enhanced in-class curricular learning and improved marine science literacy 2) increased personal connections to local marine environments, and 3) increased interest in careers in marine science, including engineering and technical positions. Despite living in close proximity to water, this was the first boat outing for many students; boat-based education trips enhanced student awareness of local environments in a way that curricular study had not. Boston trip results are being evaluated, but 3000 evaluations from similar trips in Woods Hole, MA indicate that 98% of participants gained a better understanding and appreciation of the work conducted by marine scientists, engineers, and other professionals, and 82% said their experience made them more interested in becoming involved in science at school and/or as a job.

High resolution maps of urban vegetation and biomass are powerful tools for policy-makers and community groups seeking to reduce rates of urban runoff, moderate urban heat island effects, and mitigate the effects of greenhouse gas emissions. We developed a very high resolution map of urban tree biomass, assessed the scale sensitivities in biomass estimation, compared our results with lower resolution estimates, and explored the demographic relationships in biomass distribution across the City of Boston. We integrated remote sensing data (including LiDAR-based tree height estimates) and field-based observations to map canopy cover and aboveground tree carbon storage at ∼ 1 m spatial scale. Mean tree canopy cover was estimated to be 25.5 ± 1.5% and carbon storage was 355 Gg (28.8 Mg C ha{sup −1}) for the City of Boston. Tree biomass was highest in forest patches (110.7 Mg C ha{sup −1}), but residential (32.8 Mg C ha{sup −1}) and developed open (23.5 Mg C ha{sup −1}) land uses also contained relatively high carbon stocks. In contrast with previous studies, we did not find significant correlations between tree biomass and the demographic characteristics of Boston neighborhoods, including income, education, race, or population density. The proportion of households that rent was negatively correlated with urban tree biomass (R{sup 2} = 0.26, p = 0.04) and correlated with Priority Planting Index values (R{sup 2} = 0.55, p = 0.001), potentially reflecting differences in land management among rented and owner-occupied residential properties. We compared our very high resolution biomass map to lower resolution biomass products from other sources and found that those products consistently underestimated biomass within urban areas. This underestimation became more severe as spatial resolution decreased. This research demonstrates that 1) urban areas contain considerable tree carbon stocks; 2) canopy cover and biomass may not be related to the demographic

The self-reported prevalence of asthma in the United States increased by 75% from 1980 to 1994, a trend found to be significant and evident in every region of the country. The increase was most marked in children from birth to 14 years of age; and growing evidence indicates that, as with lead poisoning, inner-city and urban populations are most at risk. Attention has turned to the role of indoor environmental risk factors, especially in homes and schools. Such factors include moisture and mold growth, pest infestation, dust mites, the building envelope, heating systems, inadequate ventilation, nitrogen dioxide, and environmental tobacco smoke. The Healthy Public Housing Initiative (HPHI) is a Boston-based community-centered research and intervention project designed to engage Boston Housing Authority residents in a collaborative process to improve respiratory health, quality of life, building conditions, and building maintenance in public housing. This article summarizes the significant research findings from four pilot studies in housing developments that laid the foundation for the larger HPHI asthma-related environmental intervention study. The research design for the pilot projects is informed by principles of community-collaborative research. The strengths of this model of research for our work are also discussed.

The U.S. Geological Survey (USGS) is conducting studies in Boston Harbor, Massachusetts Bay, and Cape Cod Bay designed to define the geologic framework of the region and to understand the transport and accumulation of contaminated sediments. The region is being studied because of environmental problems caused by the introduction of wastes for a long time, because a new ocean outfall (to begin operation in 1995) will change the location for disposal of treated Boston sewage from Boston Harbor into Massachusetts Bay, and because of the need to understand the transport of sediments and associated contaminants in order to address a wide range of management questions. The USGS effort complements and is closely coordinated with the research and monitoring studies supported by the Massachusetts Environmental Trust, the Massachusetts Bays Program, and by the Massachusetts Water Resources Authority. The USGS study includes (1) geologic mapping, (2) circulation studies, (3) long-term current and sediment transport observations, (4) measurements of contaminant inventories and rates of sediment mixing and accumulation, (5) circulation modeling, (6) development of a contaminated sediments data base, and (7) information exchange. A long-term objective of the program is to develop a predictive capability for sediment transport and accumulation.

The classical and a modified Boston brace: description and results.

Idiopathic scoliosis (IS) is characterized by the lateral deviation of the spine and constitutes a three-dimensional distortion that leads to geometric and morphological lesions in the spine and thoracic cage. The most widespread method of conservative management is to use spinal orthoses or body braces. These are usually recommended in patients with skeletal immaturity with a Risser sign 2 or less and with curves ranging from 25° to 45°. Of these, perhaps one of the most popular in recent years is the Boston Brace. It was developed in the early 1970s, and its design is based on symmetry, consisting of extensions and pads, with each of them exerting corrective forces and has a specific role depending on the type of scoliosis. It is important that the treatment group, the patient, and the family environment should work as a team consistently and be well trained to achieve the best result. Various studies published in international literature have observed beneficial effects from the use of the Boston system. Nevertheless, there are still issues that need further investigation regarding its effectiveness depending on the type of curves, the duration of application, the gender, and BMI of patients to whom it is applied. However, without question, if all these factors are taken into account and with the compliance of the therapy group with the instructions, the main goal can be achieved, which is the stability of the spine, and the ultimate result of clinical-radiological and aesthetic improvement, which is directly linked to the psychological satisfaction of the patient.

Outages of electric power supply resulting from cable failures Boston Edison Company system

Energy Technology Data Exchange (ETDEWEB)

None

1980-07-01

Factual data are provided regarding 5 electric power supply interruptions that occurred in the Boston Metropolitan area during April to June, 1979. Common to all of these outages was the failure of an underground cable as the initiating event, followed by multiple equipment failures. There was significant variation in the voltage ratings and types of cables which failed. The investigation was unable to delineate a single specific Boston Edison design operating or maintenance practice that could be cited as the cause of the outages. After reviewing the investigative report the following actions were recommended: the development and implementation of a plan to eliminate the direct current cable network; develop a network outage restoration plan; regroup primary feeder cables wherever possible to minimize the number of circuits in manholes, and to separate feeders to high load density areas; develop a program to detect incipient cable faults; evaluate the separation of the north and south sections of Back Bay network into separate networks; and, as a minimum, install the necessary facilities to make it possible to re-energize one section without interfering with the other; and re-evaluate the cathodic protection scheme where necessary.

Objectives. We sought to determine whether the socioeconomic environment was associated with no participation in physical activity among adolescents in Boston, Massachusetts. Methods. We used cross-sectional data from 1878 urban adolescents living in 38 neighborhoods who participated in the 2008 Boston Youth Survey, a biennial survey of high school students (aged 14–19 years). We used multilevel multiple regression models to determine the association between neighborhood-level exposures of economic deprivation, social fragmentation, social cohesion, danger and disorder, and students’ reports of no participation in physical activity in the previous week. Results. High social fragmentation within the residential neighborhood was associated with an increased likelihood of being inactive (odds ratio = 1.53; 95% confidence interval = 1.14, 2.05). No other neighborhood exposures were associated with physical inactivity. Conclusions. Social fragmentation might be an important correlate of physical inactivity among youths living in urban settings. Interventions might be needed to assist youths living in unstable neighborhoods to be physically active. PMID:25211727

Full Text Available Este ensaio discute a peça The Noam Chomsky Lectures, escrita e encenada pelos atores canadenses Guillermo Verdecchia e Daniel Brooks. Concebida como um “workshop perpétuo”, a obra dos dois autores/atores, em forma de “palestra” sobre a obra do conhecido intelectual Noam Chomsky, aponta para o político enquanto necessidade do dia-a-dia, ou política como “performatividade”, e encena/ensina como resistir à “manufatura do consentimento”. Através de uma forma original de fazer teatro político, a dupla de atores/personagens desenvolve uma maneira alternativa de alertar a platéia para o bombardeio gradual e uniforme da informação, cujos conteúdos são filtrados e homogeneizados, em detrimento das políticas de diversidade do mundo atual, e desconstrói as “ilusões necessárias” do povo canadense, de não-cumplicidade com este modelo. Palavras-chaves: performance e mídia; teatro político; teatro didático; “manufatura do consentimento”; “ilusões necessárias”; EUA e Canadá; política externa. This essay discusses The Chomsky Lectures, written and performed by Guillermo Verdecchia and Daniel Brooks. Conceived as a “perpetual workshop”, and structured around “lectures” on Chomsky’s ideas, the play endeavors to point to the political as an everyday necessity, or to politics as performativity, acting out/teaching how to resist the manufacture of consent. Through this form of political theater, the Canadian duo develops an alternative way to alert the audience to the gradual and uniform bombardment of information, whose filtered and homogenized contents are detrimental do contemporary policies of diversity, at the same time that they deconstruct the Canadian citizens’ “necessary illusions” about their role vis-a-vis this model.

Using the Boston Matrix at Identification of the Corporate Life Cycle Stage

Directory of Open Access Journals (Sweden)

2015-01-01

Full Text Available The main aim of this article is to develop a new model supporting the identification of the particular corporate life stage within the corporate life cycle. This model will be derived from the Boston matrix. The main reason for using this approach as the base for making new model of the corporate life cycle is the fact, that every quadrant of the Boston matrix can be assigned to one phase of the product life cycle and there is supposed, that the phase, in which are most products, determines the phase of the corporate life cycle. For application the Boston matrix by identification phases of the corporate life cycle is necessary to define low and high values of both its variables using some quantities from the model of corporate- and market life cycle by Reiners (2004. So the interval of low and high sales growth is determined by comparing sales of the company and sales of the market and furthermore, there is considered the rate of inflation to eliminate the impact of price changes. And for determination low and high market shares, there are compared the shares of sales and shares of total assets. After that, there will be possible to identify all the quadrants and thus all the individual phases unequivocally, which is the basic advantage compared to most existing models of the corporate life cycle. The following aim of this article is to compare the occurrence of individual phases, identified by this modified model, depending on the sector sensitivity to the economic cycle, measured by the coefficient of correlation between sales on the market and GDP. There are selected two sectors of the Czech economy, namely one cyclical and one neutral sector. Subsequently there is selected a sample of companies from both these sectors. The data are collected from financial statements of companies and from analytical materials by the Czech Ministry of Industry and Trade and by the Czech Statistical Office. On the basis of this research, there were recorded

Full Text Available The Landsat data archive provides a unique opportunity to investigate the long-term evolution of coastal ecosystems at fine spatial scales that cannot be resolved by ocean colour (OC satellite sensors. Recognizing Landsat’s limitations in applications over coastal waters, we have launched a series of field campaigns in Boston Harbor and Massachusetts Bay (MA, USA to validate OC products derived from Landsat-8. We will provide a preliminary demonstration on the calibration/validation of the existing OC algorithms (atmospheric correction and in-water optical properties to enhance monitoring efforts in Boston Harbor. To do so, Landsat optical images were first compared against ocean colour products over high-latitude regions. The in situ cruise data, including optical data (remote sensing reflectance and water samples were analyzed to obtain insights into the optical and biogeochemical properties of near-surface waters. Along with the cruise data, three buoys were deployed in three locations across the Harbor to complement our database of concentrations of chlorophyll a, total suspended solids (TSS, and absorption of colour dissolved organic matter (CDOM. The data collected during the first year of the project are used to develop and/or tune OC algorithms. The data will be combined with historic field data to map in-water constituents back to the early 1990’s. This paper presents preliminary analysis of some of the data collected under Landsat-8 overpasses.

Full Text Available The new tunnel under Boston harbour has been constructed because of the insufficient capacity of a similar, earlier, tunnel to cope with the ever increasing road traffic. This tunnel is 1,550 ms long, and 9.50 ms in external diameter. There are two traffic lanes, each 3.20 ms wide. Inside it is faced with ceramic tiles, has fluorescent lighting, and ventilation is maintained by means of two ducts, one at each entrance, where the necessary compressor and other equipment has been situated. The most interesting feature of this important project is the excavation method adopted for its construction: the tunnel crosses a clay layer, which at certain places is sufficiently fluid to allow a pneumatic shield to be forced through it leaving hardly any debris behind. It will be readily appreciated that this procedure shows an obvious advantage over ordinary methods, in which it is necessary to cut out, and transport to the exterior all the excavated material. The metal sheathing was by the Commercial Shearing and Stamping Co., Youngstown, Ohio.Este nuevo túnel, bajo el puerto de Boston, es una consecuencia de la necesidad imperiosa que se hacía sentir dada la insuficiente capacidad del otro túnel similar antiguo y el aumento continuo del tráfico urbano y por carretera. Tiene 1.550 m de longitud, 9,50 m de diámetro exterior y una calzada con dos bandas de circulación de 3,20 m de anchura cada una. Está revestido ccn baldosa cerámica, iluminado con luz fluorescente, y el aire viciado se ventila y renueva por medio de dos torres de ventilación—una en cada portal—, en las que se han instalado el equipo mecánico adecuado de ventilación y compresores. La parte más interesante de esta importante obra estriba en los procedimientos empleados para llevar a cabo la excavación, pues atraviesa un banco de arcilla que, en ciertos tramos, es suficientemente fluida para permitir dejarse empujar y ceder paso a un escudo neumático que avanza sin apenas

Osgood, Robert; Scanlon, Courtney; Jotwani, Rohan; Rodkey, Daniel; Arshanskiy, Maria; Salem, Deeb

Over the last decade, there has been a rise in the number of mass casualty incidences (MCIs) and their subsequent effect on hospital systems. While there has been much discussion over improving procedures to treat victims of MCIs, there has not been a thorough, systems-based analysis concerning the costs incurred by hospitals during such events. Here the authors examine the history of the Hospital Incident Command Center and how its evolution at Tufts Medical Center helped mitigate the damage following the Boston Marathon Bombings. Tufts' unique variations to the Hospital Incident Command Center include strategic communication hierarchies and a 'zero cost centre' financial system which both provided for a quick and adaptive response. Operating in collaboration with the Conference of Boston Teaching Hospitals encouraged coordination and preparation during emergency situations such as mass casualty events. The direct and indirect effects on Tufts Medical Center stemming from the Boston Marathon Bombings were analysed. Tufts MC treated 36 victims immediately following the MCI. The estimated total cost during the week of April 15 to April 19, 2013 was $776,051. The cost was primarily comprised of lost revenue from cancelled outpatient and inpatient hospital services, as well as expenses incurred due to overtime pay, salary expenses, PPE kits and hospitality services. Finally, the authors examine ways to reduce the future costs during emergency situations through increasing communication with employees, understanding the source of all direct expenses, and mitigating excess risk by developing partnerships with other hospital systems.

The post-September 11 era has prompted unprecedented attention to medical preparations for national special security events (NSSE), requiring extraordinary planning and coordination among federal, state, and local agencies. For an NSSE, the US Secret Service (USSS) serves as the lead agency for all security operations and coordinates with relevant partners to provide for the safety and welfare of participants. For the 2004 Democratic National Convention (DNC), designated an NSSE, the USSS tasked the Boston Emergency Medical Services (BEMS) of the Boston Public Health Commission with the design and implementation of health services related to the Convention. In this article, we describe the planning and development of BEMS' robust 2004 DNC Medical Consequence Management Plan, addressing the following activities: public health surveillance, on-site medical care, surge capacity in the event of a mass casualty incident, and management of federal response assets. Lessons learned from enhanced medical planning for the 2004 DNC may serve as an effective model for future mass gathering events.

"The reflection of England's light": the instructive District Nursing Association of Boston, 1884-1914.

Science.gov (United States)

Howse, Carrie

2009-01-01

This article examines the extent to which the Instructive District Nursing Association (IDNA) of Boston was influenced by the English system of district nursing. The schemes had the same aims and motivation, but the differences in their organizational structures, in particular the lack of specialist training and professional supervision of the Boston nurses, affected the IDNA's work with its poor, mainly immigrant patients. It is clear that much was achieved, but it is also apparent that problems increased as the work expanded. Attempts to solve these difficulties can be traced through the introduction of a nurse supervisor, establishment of a training school, and eventual radical reorganization. The IDNA also had a leading role in the expansion of the visiting nurse movement throughout the United States. I discuss attempts to establish national standards, particularly through the formation of the National Organization for Public Health Nursing (NOPHN). With the disparate arrangements in the U.S. health care system, the NOPHN was unable to reach a workable consensus and failed to produce a comprehensive and cohesive national system similar to that which had been established in England.

Most of the major urban centers of the United States including Boston, New York, Washington, Chicago, New Orleans, Miami, Los Angeles, San Francisco, and Seattle—are on a coast (fig. 1.1). All of these cities discharge treated sewage effluent into adjacent waters. In 2000, 74 percent of the U.S. population lived within 200 kilometers (km) of the coast. Between 1980 and 2002, the population density in coastal communities increased approximately 4.5 times faster than in noncoastal areas of the U.S. (Perkins, 2004). More people generate larger volumes of wastes, increase the demands on wastewater treatment, expand the area of impervious land surfaces, and use more vehicles that contribute contaminants to street runoff. According to the National Coastal Condition Report II (U.S. Environmental Protection Agency, 2005a), on the basis of coastal habitat, water and sediment quality, benthic index, and fish tissue, the overall national coastal condition is only poor to fair and the overall coastal condition in the highly populated Northeast is poor. Scientific information helps managers to prioritize and regulate coastal-ocean uses that include recreation, commercial fishing, transportation, waste disposal, and critical habitat for marine organisms. These uses are often in conflict with each other and with environmental concerns. Developing a strategy for managing competing uses while maintaining sustainability of coastal resources requires scientific understanding of how the coastal ocean system behaves and how it responds to anthropogenic influences. This report provides a summary of a multidisciplinary research program designed to improve our understanding of the transport and fate of contaminants in Massachusetts coastal waters. Massachusetts Bay and Boston Harbor have been a focus of U.S. Geological Survey (USGS) research because they provide a diverse geographic setting for developing a scientific understanding of the geology, geochemistry, and oceanography of

Full Text Available Fluorescence<em> em>>in situ em>hybridization (FISH assay is considered the “gold standard” in evaluating <em>HER2/neu (HER2em> gene status. However, FISH detection is costly and time consuming. Thus, we established nuclei microarray with extracted intact nuclei from paraffin embedded breast cancer tissues for FISH detection. The nuclei microarray FISH (NMFISH technology serves as a useful platform for analyzing <em>HER2em> gene/chromosome 17 centromere ratio. We examined <em>HER2em> gene status in 152 cases of invasive ductal carcinomas of the breast that were resected surgically with FISH and NMFISH. <em>HER2em> gene amplification status was classified according to the guidelines of the American Society of Clinical Oncology and College of American Pathologists (ASCO/CAP. Comparison of the cut-off values for <em>HER2em>/chromosome 17 centromere copy number ratio obtained by NMFISH and FISH showed that there was almost perfect agreement between the two methods (κ coefficient 0.920. The results of the two methods were almost consistent for the evaluation of <em>HER2em> gene counts. The present study proved that NMFISH is comparable with FISH for evaluating <em>HER2em> gene status. The use of nuclei microarray technology is highly efficient, time and reagent conserving and inexpensive.
