AbstractTwo populations of killifish, Fundulus heteroclitus (L.) were studied, one from a high environmentally impacted site (Saw Mill Creek) exposed to pollutants, heavy metals and infected with parasites, the other from a habitat that was far less affected (Lemon Creek), on Staten Island, New York. The rodlet cell counts in the gills of each population were compared and correlated with the number of gill parasites. A comparison of rodlet cell numbers was also made between mature males and females within each population. Although the parasite infestation was significantly higher in the Saw Mill Creek population, the rodlet cell counts did not differ between the two groups. There was no statistical correlation between the parasite number and number of rodlet cells or between standard length and rodlet cells in each population. Also, the number of rodlet cells did not differ between males and females in either group. Furthermore, EM observations showed no difference in the activity of these cells. Our findings suggest that in F. heteroclitus, rodlet cells are not dependable biomarkers for evaluating the fish's response to parasites and environmental stressors. In addition, the sexual status of the fish does not appear to affect the number of rodlet cells.

<p>O <em>Greenmarket Farmers</em>, como são chamados os mercados hortícolas em Nova Iorque, Estados Unidos da América, tem como uma de suas particularidades a de ser organizado por produtores rurais apoiados pelo <em>Council of Environment of the New York City </em>e cuja venda de produtos deve ser feita diretamente aos consumidores, sem intermediários. Exerce uma importante função, tanto para os agricultores quanto para o público consumidor. No presente estudo foi realizado levantamento contínuo no período de um ano (agosto de 2008 a junho de 2009) seguindo-se de visitas pontuais nos anos de 2010, 2011 e 2012 ao levantamento sistemático, um refinamento dos dados sobre as plantas hortícolas comercializadas e seus produtores no <em>Greenmarket Farmers</em>, que possuem 46 pontos de venda em Manhattan, Brooklyn, Queens, Bronx e Staten Island. Neste período foram observados aspectos de entrelaçamento entre produtores rurais e consumidores urbanos, além da diversidade vegetal. Foram levantadas 120 espécies de plantas comercializadas por 60 produtores, nos diversos pontos do Green Market. Foram listadas 38 famílias botânicas, inseridas em 84 gêneros. A família mais recorrente é Brassicaceae (18), seguida de Asteraceae (13), Lamiaceae (12) e Rosaceae (12). Aspecto que se revela nestas feiras é a face agrícola do estado de Nova Iorque, em geral representado por atividades de turismo e do centro financeiro do mais poderoso país do mundo, e uma das maiores concentrações populacionais do planeta. O apelo ecológico, o estímulo ao consumo de produtos locais e a concessão de cupons de beneficio cedidos às pessoas em dificuldade<a title="" href="file:///C:/Users/Eraldo/Documents/02%20-%20Vivencias%20e%20tecnicas%20de%20relaxamento/Green%20market.NYC%20%2010_Out_2018%20Daniel%20GG%20(1).doc#_ftn1">[1]</a>, em uma comunidade cosmopolita e multi-étnica, canalizam recursos públicos e apoiam este tipo de mercado, permitindo uma reflexão sobre as relações e interatividade entre rural e urbano, diluídas pelas características próprias aos países desenvolvidos, em especial em grandes cidades. Portanto, percebe-se com este trabalho que os “greenmarkets” são pontos não só de venda de grande diversidade de vegetais, mas também local para relacionamentos, trocas de experiências e ideologias.</p><div><br clear="all" /><hr align="left" size="1" width="33%" /><div><p><a title="" href="file:///C:/Users/Eraldo/Documents/02%20-%20Vivencias%20e%20tecnicas%20de%20relaxamento/Green%20market.NYC%20%2010_Out_2018%20Daniel%20GG%20(1).doc#_ftnref1">[1]</a> Os cupons podem ser usados em qualquer supermercado ou nos Greenmarkets.</p></div></div>

<p>The Port Authority of New York and New Jersey has completed the replacement of the congested and functionally obsolete Goethals Bridge, a circa 1928 steel cantilever truss bridge, with a dual-span modern cable-stayed bridge connecting Elizabeth, New Jersey and Staten Island, NY. Designed as a 150 year service life structure, the newly opened crossing paves the way towards achieving the possibility of a 200 year bridge, both in material durability, structural redundancy / resilience, and modal flexibility.</p><p>The new crossing features three eastbound and three westbound lanes plus a 3 m wide shared use path (SUP) for bicycles and pedestrians. To accommodate future expansion, the superstructure of the cable stayed spans is designed to receive steel framing to support a variety of possible transit options including light rail, while the substructure need not be strengthened for this future load. With a 274 m main span, the new crossing provides a significant maritime navigational improvement over the original 205 m steel truss span.</p><p>Herein we focus on the strategic application of corrosion protection strategies to achieve the long service life in a competitive bid environment, structural benefit of the design as relates to resiliency, modal flexibility, and operational redundancy to withstand extreme events.</p>

This chapter provides a background of the waterborne evacuation that happened after the events of 9/11. New York harbor was, and is, a busy place — the third largest container port in the United States and a vital connection between New York City and the rest of the world. Manhattan is an island, and the realities of island real estate are what ushered the port's industries off Manhattan's shores and over to Brooklyn, Staten Island, and New Jersey in the 1960s and 1970s. By late 2001, maritime infrastructure had been replaced with ornamental fencing. On September 11, 2001, as the cascade of catastrophe unfolded, people found their fates altered by the absence of that infrastructure and discovered themselves dependent upon the creative problem solving of New York harbor's maritime community — waterfront workers who had been thrust beyond their usual occupations and into the role of first responders. Long before the U.S. Coast Guard's call for “all available boats” crackled out over marine radios, scores of ferries, tugs, dinner boats, sailing yachts, and other vessels had begun converging along Manhattan's shores. Hundreds of mariners shared their skills and equipment to conduct a massive, unplanned rescue. Within hours, nearly half a million people had been delivered from Manhattan by boat.

AbstractIt is clear from disaster evaluations that communities must be prepared to act independently before government agencies can cope with the early ramifications of disasters. In response to devastation to the borough of Staten Island, New York in the wake of 11 September 2001, the Richmond County Medical Society established a structure to incorporate community needs and institutions to work together for the common good. A program that brings together two hospital systems, nursing homes, emergency medical services, and the Office of Emergency Management physician leadership in a meaningful way now is in place. This approach has improved the disaster preparedness of Staten Island and demonstrated how the Medical Society can provide leadership in disaster preparedness and serve as a conduit for communication amongst entities that normally do not communicate.

Bulk tank milk samples and quarter samples from 15,982 cows were collected from 285 herds enrolled in the New York State Mastitis Control Program. Culture and strip-plate examination findings from quarter samples were correlated with bulk milk cell counts. A correlation of 0.50 was found between percent quarters yielding mastitis pathogens and bulk milk cell counts. A correlation of 0.51 was found between percent quarters producing abnormal secretions and bulk milk cell counts. These relationships indicated the bulk milk cell count was not a reliable measure of herd infection or prevalence of abnormal secretion. The most prominent trend in a relationship between pathogens and increased bulk milk cell count was found for Streptococcus agalactiae and a lesser relationship between staphylococci and increased bulk milk cell count. Herds classified as having low bulk milk cell counts produced an average of 1,759 lb. of milk more than herds with high bulk milk cell counts. Only three milking and management practices were found to be associated with bulk milk cell counts.

Although there is an increase in attention being paid to race and sex variations in crime and delinquency, little has been done to disaggregate the “gender-ratio” problem in order to account for participation in particular offenses, specifically different types of violent crime. Virtually all of the research pertaining to the interaction of gender, race and -violent crime focuses on murder and dichotomizes race into white and black, or white and nonwhite. This paper uses New York City arrest data to examine the extent of violence within various race-sex-crime subgroups. Rates of violent offending (i.e., homicide, robbery, assault, and burglary) are presented for black, Hispanic and white males and females. Regardless of violent crime type, black and Hispanic females exhibited high rates of offending relative to white females. Furthermore, the violent offending rates of black females paralleled those of white males. These findings suggest that an examination of gender differences in violent offending, independent of race, will produce incomplete and potentially misleading interpretations. The paper also provides a social structural explanation of the disproportionate involvement of black females (and males) in violent crime.
