A produção de etanol e a dominação da indústria, historicamente, tem sido uma fonte de discórdia para seus dois principais produtores. Os EUA com seu etanol de milho e o Brasil com sua etanol de cana, são os dois maiores produtores mundiais de etanol (1º EUA; 2º Brasil) e tem competido pela participação de mercado mundial há décadas. A partir de Dezembro de 2011, os EUA levantaram as tarifas e os subsídios que foram instalados para proteger sua indústria de etanol, o que muda o campo de jogo da produção mundial de etanol para o futuro. Atualmente em todo o mundo, o etanol é usado em uma proporção muito menor comparativamente a outros combustíveis. Esta pesquisa analisa o nível potencial de colaboração entre os EUA e o Brasil, facilitando um diálogo entre os stakeholders em etanol. A pesquisa consiste principalmente de conversas e entrevistas, com base em um conjunto de perguntas destinadas a inspirar conversas detalhadas e expansivas sobre os temas de relações Brasil-EUA e etanol. Esta pesquisa mostra que o etanol celulósico, que é também conhecido como etanol de segunda geração, oferece mais oportunidades de parceria entre os EUA e o Brasil, como há mais oportunidades para pesquisa e desenvolvimento em conjunto e transferência de tecnologia nesta área. Enquanto o etanol de cana no Brasil ainda é uma indústria próspera e crescente...

O presente trabalho tem por objetivo demonstrar que a criação do Oriente Médio foi estabelecida pelos europeus para a exploração do petróleo, que passou a ser explorado intensamente desde o início do século. A penetração estadunidense na região ocorre no mesmo período, enquanto busca afirmar a sua influência na América Latina, que ainda mantinha fortes ligações com a Europa. As duas guerras mundiais intensificam a presença estadunidense no Oriente Médio e na América do Sul interferindo decisivamente nas relações internacionais de ambas regiões. Com a Guerra Fria, os EUA passaram a atuar decisivamente nas políticas externas de nações importantes estrategicamente como Brasil e Iraque, que passaram a colaborar com os interesses estadunidenses nas duas regiões, no combate à penetração soviética e à Revolução Islâmica, apesar de desenvolverem estratégias próprias para alcançar este objetivo e outros que lhes favoreciam diretamente. A presença brasileira no Oriente Médio foi permitida ainda que tardiamente, sendo que a relação privilegiada com o Iraque gerou uma cooperação extremamente benéfica para ambos, favorecendo também os planos dos EUA para o Oriente Médio, enquanto o Brasil auxiliava o governo estadunidense a conter movimentos de guerrilha na América Central. Com a queda do Império Soviético...

What role does the formal teaching of innovation management play? Courses in Europe and the USA are reviewed, especially two courses, MIETE, taught at the University of Porto, in Portugal, and the Stanford University and Michigan University model from the USA. As these flagship courses have resulted in real innovations being introduced into the market formal teaching may well play a decisive role in the larger scenario of real innovation management. A literature review was performed and these two aforementioned cases studied in depth – MIETE via repeated contact with its Director and through the analysis of other publicly available information; while the Stanford University and Michigan University model was analysed by way of a comprehensive publication. A model for innovation and entrepreneurship is put forward whereby personal characteristics, the environment, and career experience and formal teaching will all play a part in the output of innovation and entrepreneurship in society.

The hydrodynamics of tree islands during the growth of newly planted trees has been found to be influenced by both vegetation biomass and geologic conditions. From July 2007 through June 2009, groundwater and surface-water levels were monitored on eight recently planted tree islands at the Loxahatchee Impoundment Landscape Assessment (LILA) facility in Boynton Beach, Florida, USA. Over the 2-year study, stand development coincided with the development of a water-table depression in the center of each of the islands that was bounded by a hydraulic divide along the edges. The water-table depression was greater in islands composed of limestone as compared to those composed of peat. The findings of this study suggest that groundwater evapotranspiration by trees on tree islands creates complex hydrologic interactions between the shallow groundwater in tree islands and the surrounding surface water and groundwater bodies.

Two deep-well injection sites in south Florida, USA, inject an average of 430 million liters per day (MLD) of treated domestic fresh wastewater into a deep saline aquifer 900 m below land surface. Elevated levels of NH3 (highest concentration 939 µmol) in the overlying aquifer above ambient concentrations (concentration less than 30 µmol) were evidence of the upward migration of injected fluids. Three pathways were distinguished based on ammonium, chloride and bromide ratios, and temperature. At the South District Wastewater Treatment Plant, the tracer ratios showed that the injectate remained chemically distinct as it migrated upwards through rapid vertical pathways via density-driven buoyancy. The warmer injectate (mean 28°C) retained the temperature signal as it vertically migrated upwards; however, the temperature signal did not persist as the injectate moved horizontally into the overlying aquifers. Once introduced, the injectate moved slowly horizontally through the aquifer and mixed with ambient water. At the North District Wastewater Treatment Plant, data provide strong evidence of a one-time pulse of injectate into the overlying aquifers due to improper well construction. No evidence of rapid vertical pathways was observed at the North District Wastewater Treatment Plant.

Gegenstand der vorliegenden Arbeit ist die Untersuchung multikultureller, das heißt fremdsprachiger und/oder ausländischer Einflüsse auf die Rundfunklandschaften in Deutschland und den USA, sowie deren Eingliederung in die herrschende Rechtsordnung. Es soll gezeigt werden, wie die beiden Rechtsordnungen hiermit umgehen und ob und gegebenenfalls wie sie multikulturelle Einflüsse zulassen oder integrieren. Ausgangspunkt der Untersuchung sind die jeweiligen verfassungsrechtlichen Grundlagen und die darauf aufbauenden Rundfunksysteme. Dabei soll zunächst ermittelt werden, ob das jeweilige Rundfunksystem die Produktion und Ausstrahlung fremdsprachiger Sendungen zulässt oder sogar fordert. Weiter wird untersucht, ob ausländische Sender die Möglichkeit haben, Teil der jeweiligen Rundfunklandschaft zu werden. Angesprochen wird ebenfalls die Problematik des grenzüberschreitenden Rundfunks, wobei im deutschen Teil auch auf die Besonderheit der Einbettung in ein europäisches Gefüge eingegangen wird. Ferner wird geprüft, ob der Empfang multikulturellen Rundfunks in Form von ausländischen Sendern geschützt ist und wie die jeweilige Rechtsordnung diese Frage löst. Gesondert eingegangen wird dabei auf die Frage nach der Zulässigkeit der Installation von Parabolantennen zum Empfang ausländischer Rundfunksendungen.; The present study shall analize how multicultural influence affects the braodcasting systems of Germany and the USA. It will be surveyed if and how multicultural influence is integrated into the respective legal system. Multcultural influence hereby means the influence of foreign languages and and of foreign countries in general. Point of origin of the analysis are the constitutions and the broadcasting systems of Germany and the USA which will be presented at the beginning of the work. The study then examins if the respective broadcasting system allows the production and broadcasting of foreign language programs. After that the question is answered if foreign broadcasting stations may get part of the national broadcasting environment. Part of the analisation is also the problem of transnational broadcasting...

Gegenstand der Arbeit ist einerseits die Forschung und andererseits die Gesetzgebung zur Behandlung rückfallgefährdeter Sexualstraftäter in Deutschland, den USA und den Niederlanden. Untersucht werden für diese exemplarisch ausgewählten Rechtsräume zunächst die geschichtlichen und gesellschaftlichen Hintergründe der Kriminalpolitik im Umgang mit Sexualstraftätern. In einem jeweils zweiten Kapitel wird der aktuelle Forschungsstand möglichst umfassend dargestellt. Hierbei gilt das Augenmerk insbesondere Untersuchungen zu Rückfälligkeit und zur Wirksamkeit von Behandlungsmaßnahmen. Das jeweils dritte Kapitel beschäftigt sich mit der kriminalpolitischen und gesetzgeberischen Entwicklung des Umgangs mit besonders rückfallgefährdeten Sexualstraftätern bis in die jüngste Zeit. Hierbei soll nachvollzogen werden, ob und gegebenenfalls inwieweit der Gesetzgeber die gefundenen Untersuchungsergebnisse in seinen gesetzgeberischen Aktivitäten berücksichtigt hat. Es werden auch Vergleiche zwischen den jeweilig untersuchten Rechtsräumen gezogen. Nachgezeichnet werden die Reformen zur Sexualstraftätergesetzgebung seit Mitte der Neunziger Jahre. Für den deutschen Teil sind dies insbesondere das 6. Strafrechtsreformgesetz und das Gesetz zur Bekämpfung von Sexualdelikten und anderen gefährlichen Straftaten. Weiter sind behandelt die Gesetze zur Einführung der vorbehaltenen (§§ 66a [2002]) und der nachträglich angeordneten Sicherungsverwahrung (§ 66b StGB [2004]) sowie das Gesetz zur Änderung der Vorschriften über die Straftaten gegen die sexuelle Selbstbestimmung im Jahre 2003. Diese Gesetzesreformen werden verglichen mit ähnlichen Sicherungsgesetzen und Gesetzen zur Behandlung und Kontrolle von Sexualstraftätern in Nordamerika und den Niederlanden. Stand von Rechtsprechung und Gesetzgebung ist September 2004.; This study analyses research and legislation on the treatment of sexual offenders...

Gegenstand der Arbeit ist die Untersuchung der bestehenden Forschung zu Gewalt an Schulen in Deutschland und den USA. Die Arbeit geht der Frage nach ob es empirisch gesichertes Wissen zum Ausmaß und der Entwicklung von Gewalt an deutschen und amerikanischen Schulen gibt. Im ersten Kapitel der Arbeit wird der Gewaltbegriff definiert. Dabei wird zunächst der juristische Gewaltbegriff kurz erörtert und im Anschluss daran das den empirischen Untersuchungen zugrundeliegende Gewaltverständnis aufgezeigt. Dabei werden die Befunde einiger Studien zum Gewaltverständis der Befragten dargelegt und es zeigt sich, dass die befragten Schüler von einem relativ engen Gewaltverständnis ausgehen während die Mehrzahl der Forscher ihren Untersuchungen einen sehr weiten Gewaltbegriff zugrunde legen. Im zweiten Kapitel werden die Ergebnisse der deutschen Untersuchungen zum Gewaltausmaß an Schulen aufgezeigt. Die Untersuchungen zu diesem Themenbereich werden dabei kritisch analysiert und Mängel an den bestehenden Forschungen aufgezeigt. Das Gewaltausmaß an Schulen wird aus Täter-, Oper- und Wahrnehmungsperspektive dargelegt. Neben tatsächlichen Gewaltvorfällen werden in diesem Abschnitt auch die Ergebnisse der Studien zum Tragen von Waffen untersucht...

Die Forschungsarbeit vergleicht die Entwicklung der Sonderabfallpolitik in Deutschland, Kanada und den USA 1970 bis 1996. Sie nimmt Bezug auf die Konvergenzhypothese, die mit fortschreitender technischer Entwicklung eine Angleichung von Strukturen, Prozessen und politischer Steuerungsfähigkeit in Industriegesellschaften postuliert. Ziele und Schwerpunkte der Sonderabfallpolitik in Deutschland, Kanada und den USA haben identische Entwicklungsphasen - von der Einrichtung einfacher Kontrollsysteme über die Entwicklung von Umweltstandards für die Sonderabfallentsorgung hin zu internationalen Kontrollregimen - durchlaufen. Die Entwicklungsphasen resultierten primär aus Anpassungsreaktionen zwischen Regulation und Wirtschaft. Unterschiede gibt es bei der Wahl regulativer Ansätze, technischer und administrativer Standards sowie von Politikinstrumenten. Maßgeblich hierfür sind unterschiedliche verfassungs- und umweltrechtlichen Rahmenbedingungen der Sonderabfallpolitik. Lediglich bei der Kontrolle von Im- und Exporten sowie in wenigen Teilaspekten der technischen Standards für Sonderabfallverbrennungsanlagen haben internationale Zusammenarbeit bzw. transnationaler Wissenstranfer innenpolitische Faktoren im Policyprozeß überlagert und zu konvergenten Politikentwicklungen geführt. Die Ergebnisse zeigen...

Es wird die Frage untersucht, ob die Europäische Union als aussenpolitischer Akteur bezeichnet werden kann. In einem ersten Teil werden mögliche Modelle für die EU als aussenpolitischem Akteur diskutiert: Zunächst in der Perspektive des Vökerrechts, dann in der Perspektive der Internationalen Beziehungen. Bei letzterem wird das "Principal Agent"-Modell, institutionelle und substanzielle Modelle und die Zivilmachtsrhetorik vorgestellt. In einer Bestandsaufnahme der Transatlantischen Beziehungen werden die gegenwärtige Rolle der USA in der Weltpolitik, zunehmende Spannungen im transatlantischen Verhältnis und Spannungen innerhalb EU-Europas dargestellt. Ein letzter Teil gibt dann "Empfehlungen" in Form von Handlungsoptionen einer europäischen Außenpolitik gegenüber den USA. Diskutiert werden hier die Konzepte eines Kollektiven Balancing, eines Kollektiven Bandwagoning und eines Leitbildes der Zivilmacht.; The research paper deals with the questions, if the European Union could be indicated as an actor in international relations. In the first part are several possible models discussed: At first in the perspective of the international law, then in the perspective of the international relations. In the latter case, three models are presented: the "principal agent" model...

Objectives: Using generic measures to examine outcomes of oral disorders can add additional information relating to health utility. However, different algorithms are available to generate health states. The aim was to assess UK-, US- and Australian-based algorithms for the EuroQol (EQ-5D) in relation to their discriminative and convergent validity. Methods: Data were collected from adults in Australia aged 30-61 years by mailed survey in 2009-10, including the EQ-5D and a range of self-reported oral health variables, and self-rated oral and general health. Results: Responses were collected from n=1,093 persons (response rate 39.1%). UK-based EQ-5D estimates were lower (0.85) than the USA and Australian estimates (0.91). EQ-5D was associated (p<0.01) with all seven oral health variables, with differences in utility scores ranging from 0.03 to 0.06 for the UK, from 0.04 to 0.07 for the USA, and from 0.05 to 0.08 for the Australian-based estimates. The effect sizes (ESs) of the associations with all seven oral health variables were similar for the UK (ES=0.26 to 0.49), USA (ES=0.31 to 0.48) and Australian-based (ES=0.31 to 0.46) estimates. EQ-5D was correlated with global dental health for the UK (rho=0.29), USA (rho=0.30) and Australian-based estimates (rho=0.30)...

This paper looks at the main finding by Amorim Neto (2011), namely that Brazil's power explains why it distanced itself from the country that had once been its great ally in the first half of the last century. We propose an alternative explanation grounded on the realist literature in IR. Ultimately, we seek to determine whether the variable has behaved in the same way for other South American countries, searching for independent variables that could help us explain a visible pattern in the region: the increasing distancing from the United States (USA) at the United Nations General Assembly. We want to contribute to the debate initiated by Amorim Neto (2011) and Schenoni (2012) for future research in the recent field of quantitative analysis of Brazilian Foreign Policy. Using Panel Corrected Standard Error analysis in ten South American countries from 1970 to 2007 we empirically prove that the lower the power gap between a South American country and the U.S., the lower its alignment with the USA in the UN General Assembly voting.

This is the accepted version of the article. The original publication of the Version of Record was in International Sociology November 2013 vol. 28 no. 6 645-662 and is available online at http://iss.sagepub.com/content/28/6/645.; This article draws a distinction between religion as heritage and as belief, and also shows the complications which arise in predominantly Christian countries when ?new arrivals? and evangelical, Pentecostal, or conversion-led, movements claim the recognition which has historically been afforded to hegemonic churches. Using evidence from Europe, the USA and Brazil it reveals the uncertain implementation of the state?religion boundary in the law, in taxation and in politics, and shows how even the most secular states allow religious institutions special exemptions, albeit in different ways. It asks whether religion is not producing demands amounting to a separate citizenship and why religious expression should require privileged treatment additional to freedom of speech in a secular world where religious affiliation is regarded as a matter of personal choice. It also questions the assumption of market theories of religion that more and more intense religion is good for religion and good for society.; This work was supported by the Arts and Humanities Research Council [grant number AH/F007566/1].

The natural and pumping-induced controls on groundwater salinization in the coastal aquifers of North Carolina, USA, and the implications for the performance of a reverse osmosis (RO) desalination plant have been investigated. Since installation of the well field in the Yorktown aquifer in Kill Devil Hills of Dare County during the late 1980s, the groundwater level has declined and salinity of groundwater has increased from ∼1,000 to ∼2,500 mg/L. Geochemical and boron isotope analyses suggest that the salinity increase is derived from an upflow of underlying saline groundwater and not from modern seawater intrusion. In the groundwater of four wells supplying the plant, elevated boron and arsenic concentrations were observed (1.3–1.4 mg/L and 8–53 μg/L, respectively). Major ions are effectively rejected by the RO membrane (96–99% removal), while boron and arsenic are not removed as effectively (16–42% and 54–75%, respectively). In coming decades, the expected rise of salinity will be associated with higher boron content in the groundwater and consequently also in the RO-produced water. In contrast, there is no expectation of an increase in the arsenic content of the salinized groundwater due to the lack of increase of arsenic with depth and salinity in Yorktown aquifer groundwater.

The study asked how well Achenbach's 8-factor cross-informant model for the Child Behavior Checklist (Achenbach, 1991a, 1991b, 1991c) fits clinic data in the USA, Holland, and Australia. DeGroot et al.'s Dutch 8-factor model (DeGroot, Koot, and Verhulst 1994) was also tested for its cross-cultural generalizability. Achenbach's matched clinical sample data (N = 2110) were analyzed and contrasted with the previously reported Dutch findings (N = 2335), as well as a new data set collected on clinic referred children and adolescents in Australia (N = 2237). Confirmatory factor analyses supported the Dutch as much as the American model in the USA, Holland, and Australia. Although about 90% of items showed convergent validity across models and countries, the attention and especially the social problems factor found least support. Most double loadings in the current models were not upheld. Instead, additional analyses discovered a number of unmodelled loadings including many cross-loadings. This led to the redefinition of the social problems factor as a mean aggression factor (with associated social problems) whereas the original aggression factor focuses on emotional acting out and the delinquent factor describes an evasive, covert type of antisocial behavior. Overall most support was obtained for the withdrawn...

The USA National Phenology Network (www.usanpn.org) has recently initiated a national effort to encourage people at different levels of expertise—from backyard naturalists to professional scientists—to observe phenology and contribute to a national database that will be used to greatly improve our understanding of spatio-temporal variation in phenology and associated phenological responses to climate change. Many phenological observation protocols identify specific single dates at which individual phenological events are observed, but the scientific usefulness of long-term phenological observations can be improved with a more carefully structured protocol. At the USA-NPN we have developed a new approach that directs observers to record each day that they observe an individual plant, and to assess and report the state of specific life stages (or phenophases) as occurring or not occurring on that plant for each observation date. Observations of animal phenophases are similarly recorded, although for a species as a whole rather than for a specific individual. Evaluation is phrased in terms of simple, easy-to-understand, questions (e.g. “Do you see open flowers?”) which makes it appropriate for a broad audience. From this method...

During a study of the endohelminths of wading birds from the Texas Gulf coast, 12 specimens of an undescribed species of Patagifer Dietz, 1909 (Echinostomatidae: Nephrostominae) were collected from 2 of 8 white ibis, Eudocimus albus (Linnaeus) (Threskiornithidae), from the Galveston and Brazos County areas of Texas, USA. Patagifer lamothei n. sp. can be distinguished from P. bilobus (Rudolphi, 1819), P. brygooi Richard, 1964, P. consimilis Dietz, 1909, and P. fraternus Johnston, 1917, where the testes are close together (contiguous to nearly contiguous), the ovary is close to the anterior testis (a distance that is less than the length of the ovary), and the posttesticular space is less extensive, by having the testes separated from each other by a distance approximately equal to or greater than the length of the ovary, the ovary positioned about the length or longer of the ovary from the anterior testis, and by having a more extensive posttesticular space. In addition, the ovary of the new species is located just ahead of midbody rather than being at midbody, as is seen in P. bilobus, P. fraternus, and P. vioscai Lumsden, 1962, or below midbody, as is the case in P. brygooi and P. consimilis. The new species is most like P. simarai Nigam...
