    1991-01-01

    For the last 6 years, the Massachusetts Institute of Technology (MIT) Nuclear Reactor Laboratory's academic and scientific staff a have been conducting evening seminars for precollege science teachers, parents, and high school students from the New England area. These seminars, as outlined in this paper, are intended to give general information on nuclear technologies with specific emphasis on radiation physics, nuclear medicine, nuclear chemistry, and ongoing research activities at the MIT research reactor. The ultimate goal is to create interest or build on the already existing interest in science and technology by, for example, special student projects. Several small projects have already been completed ranging from environmental research to biological reactions with direct student involvement. Another outcome of these seminars was the change in attitudes of science teachers toward nuclear technology. Numerous letters have been received from the teachers and parents stating their previous lack of knowledge on the beneficial aspects of nuclear technologies and the subsequent inclusion of programs in their curriculum for educating students so that they may also develop a more positive attitude toward nuclear power

  2. The MIT Integrated Global System Model: A facility for Assessing and Communicating Climate Change Uncertainty (Invited)

    The world is facing major challenges that create tensions between human development and environmental sustenance. In facing these challenges, computer models are invaluable tools for addressing the need for probabilistic approaches to forecasting. To illustrate this, I use the MIT Integrated Global System Model framework (IGSM; http://globalchange.mit.edu ). The IGSM consists of a set of coupled sub-models of global economic and technological development and resultant emissions, and physical, dynamical and chemical processes in the atmosphere, land, ocean and ecosystems (natural and managed). Some of the sub-models have both complex and simplified versions available, with the choice of which version to use being guided by the questions being addressed. Some sub-models (e.g.urban air pollution) are reduced forms of complex ones created by probabilistic collocation with polynomial chaos bases. Given the significant uncertainties in the model components, it is highly desirable that forecasts be probabilistic. We achieve this by running 400-member ensembles (Latin hypercube sampling) with different choices for key uncertain variables and processes within the human and natural system model components (pdfs of inputs estimated by model-observation comparisons, literature surveys, or expert elicitation). The IGSM has recently been used for probabilistic forecasts of climate, each using 400-member ensembles: one ensemble assumes no explicit climate mitigation policy and others assume increasingly stringent policies involving stabilization of greenhouse gases at various levels. These forecasts indicate clearly that the greatest effect of these policies is to lower the probability of extreme changes. The value of such probability analyses for policy decision-making lies in their ability to compare relative (not just absolute) risks of various policies, which are less affected by the earth system model uncertainties. Given the uncertainties in forecasts, it is also clear that

    Full Text Available An all-volunteer organization called the Opensource Opencourseware Prototype System (OOPS, headquartered in Taiwan, was initially designed to translate open source materials from MIT OpenCourseWare (OCW site into Chinese. Given the recent plethora of open educational resources (OER, such as the OCW, the growing use of such resources by the world community, and the emergence of online global education communities to localize resources such as the OOPS, a key goal of this research was to understand how the OOPS members negotiate meanings and form a collective identity in this cross-continent online community. To help with our explorations and analyses within the OOPS translation community, several core principles from Etienne Wenger’s concept of Communities of Practice (COP guided our analyses, including mutual engagement, joint enterprise, shared repertoire, reification, and overall identity of the community. In this paper, we detail how each of these key components was uniquely manifested within the OOPS. Three issues appeared central to the emergence, success, and challenges of the community such as OOPS: 1 strong, stable, and fairly democratic leadership; 2 participation incentives; and 3 online storytelling or opportunities to share one’s translation successes, struggles, and advice within an asynchronous discussion forum. While an extremely high level of enthusiasm among the OOPS members underpinned the success of the OOPS, discussion continues on issues related to quality control, purpose and scope, and forms of legitimate participation. This study, therefore, provides an initial window into the emergence and functioning of an online global education COP in the OER movement. Future research directions related to online global educational communities are discussed.

    2015-11-01

    Global health education is increasingly acknowledged as an opportunity for medical schools to prepare future practitioners for the broad health challenges of our time. The purpose of this study was to describe the evolution of global health education in Swedish medical schools and to assess students' perceived needs for such education. Data on global health education were collected from all medical faculties in Sweden for the years 2000-2013. In addition, 76% (439/577) of all Swedish medical students in their final semester answered a structured questionnaire. Global health education is offered at four of Sweden's seven medical schools, and most medical students have had no global health education. Medical students in their final semester consider themselves to lack knowledge and skills in areas such as the global burden of disease (51%), social determinants of health (52%), culture and health (60%), climate and health (62%), health promotion and disease prevention (66%), strategies for equal access to health care (69%) and global health care systems (72%). A significant association was found between self-assessed competence and the amount of global health education received (pcurriculum. Most Swedish medical students have had no global health education as part of their medical school curriculum. Expanded education in global health is sought after by medical students and could strengthen the professional development of future medical doctors in a wide range of topics important for practitioners in the global world of the twenty-first century. © 2015 the Nordic Societies of Public Health.

  6. Globalization and Conflict Management in Schools

    Directory of Open Access Journals (Sweden)

    2009-12-01

    Full Text Available Globalization has brought many changes on the education systems and schools. These changes will be exemplified from thebasis of school finance, employee rights, curriculum, administration, and school-environment relations in this study. The studyalso reviews common types of conflicts experienced at schools as a result of globalization and the ways in which conflict couldbe managed. Following topics were discussed in the article: ‘Conflicts emerged from perspectives towards globalization,conflicts emerged from cross cultural differences, conflicts sourced from changes in the teaching and learning processes,conflicts sourced from the standardization efforts, conflicts sourced from the change in school-parents relations, conflictssourced from the process of finance related activities and conflicts sourced from information, communication andeducational technologies’. This article argues that schools cannot be isolated from the effects of globalization. Therefore sinceconflict is a normal occurrence in schools, school administrators should discover constructive approaches through carefuldiagnosis and an approach that transforms the conflicting situations into constructive experiences for the school and theeducation.

  9. An integrated assessment modeling framework for uncertainty studies in global and regional climate change: the MIT IGSM-CAM (version 1.0)

    Monier, E.; Scott, J. R.; Sokolov, A. P.; Forest, C. E.; Schlosser, C. A.

    2013-12-01

    This paper describes a computationally efficient framework for uncertainty studies in global and regional climate change. In this framework, the Massachusetts Institute of Technology (MIT) Integrated Global System Model (IGSM), an integrated assessment model that couples an Earth system model of intermediate complexity to a human activity model, is linked to the National Center for Atmospheric Research (NCAR) Community Atmosphere Model (CAM). Since the MIT IGSM-CAM framework (version 1.0) incorporates a human activity model, it is possible to analyze uncertainties in emissions resulting from both uncertainties in the underlying socio-economic characteristics of the economic model and in the choice of climate-related policies. Another major feature is the flexibility to vary key climate parameters controlling the climate system response to changes in greenhouse gases and aerosols concentrations, e.g., climate sensitivity, ocean heat uptake rate, and strength of the aerosol forcing. The IGSM-CAM is not only able to realistically simulate the present-day mean climate and the observed trends at the global and continental scale, but it also simulates ENSO variability with realistic time scales, seasonality and patterns of SST anomalies, albeit with stronger magnitudes than observed. The IGSM-CAM shares the same general strengths and limitations as the Coupled Model Intercomparison Project Phase 3 (CMIP3) models in simulating present-day annual mean surface temperature and precipitation. Over land, the IGSM-CAM shows similar biases to the NCAR Community Climate System Model (CCSM) version 3, which shares the same atmospheric model. This study also presents 21st century simulations based on two emissions scenarios (unconstrained scenario and stabilization scenario at 660 ppm CO2-equivalent) similar to, respectively, the Representative Concentration Pathways RCP8.5 and RCP4.5 scenarios, and three sets of climate parameters. Results of the simulations with the chosen

    2015-12-01

    Global Systems Science (GSS), a high school integrated interdisciplinary science project based at Lawrence Hall of Science at UC Berkeley, began in the early 1990s as a single book "Planet at Risk" which was only about climate change. Federal grants enabled the project to enlist about 150 teachers to field test materials in their classes and then meeting in summer institutes to share results and effect changes. The result was a series of smaller modules dealing not only with climate change, but other related topics including energy flow, energy use, ozone, loss of biodiversity, and ecosystem change. Other relevant societal issues have also been incorporated including economics, psychology and sociology. The course has many investigations/activities for student to pursue, interviews with scientists working in specific areas of research, and historical contexts. The interconnectedness of a myriad of small and large systems became an overarching theme of the resulting course materials which are now available to teachers for free online at http://www.globalsystemsscience.org/

    Full Text Available In this paper we reflect on the issue of school violence under the light of the theoretical framework of Imaginary. The theme imaginary with regard to the school as institution is analyzed dealing with some characteristics of the society pointed out by different authors, such as Sennett (2006, Taylor (2006, and Baumann (2005.Some of the data from the research carried out with teachers of two schools of the interior of the state of Sao Paulo are presented, highlighting the imaginary on the school and the relations established in this context. This research adopted as its methodology for data collection a group dynamics.In conclusion, we stress the importance that studies on school violence try to clarify the different institutional aspects focusing not only the students and their families, but the interactions within the school. An institutional analysis focusing the micro and macrosocial aspects may contribute in order to lead the school to begin coping with the problems in a more realistic perspective, looking for alternatives in the group itself to evidence barriers raised by the institutional imaginary.

    Morimura, Kumiko

    Globalization is one of the most important challenges for universities. Especially for the School of Engineering, it is crucial to foster researchers or engineers with broader perspective. International communication competency is essential for them in order to deal with other professionals from overseas. Center for Innovation in Engineering Education established in the School of Engineering at the University of Tokyo in 2005 started two programs for graduate and undergraduate students to enhance their international communication competency and to increase international competitiveness. ‘English for Scientists and Engineers A, B’ are for the graduate students to learn how to write papers in English and how to make good presentations. Special English Lessons are for the undergraduate students to have a chance to practice English conversation or prepare for TOEFL test. In this paper, the authors discuss the details of the programs, their purpose and the future tasks.

    2014-08-28

    The issue of childhood overweight and obesity has become a global public health crisis. School-based interventions have been developed and implemented to combat this growing concern. The purpose of this review is to compare and contrast U.S. and international school-based obesity prevention interventions and highlight efficacious strategies. A systematic literature review was conducted utilizing five relevant databases. Inclusion criteria were: (1) primary research; (2) overweight or obesity prevention interventions; (3) school-based; (4) studies published between 1 January 2002 through 31 December 2013; (5) published in the English language; (6) child-based interventions, which could include parents; and (7) studies that reported outcome data. A total of 20 interventions met the inclusion criteria. Ten interventions each were implemented in the U.S. and internationally. International interventions only targeted elementary-aged students, were less likely to target low-income populations, and were less likely to be implemented for two or more years in duration. However, they were more likely to integrate an environmental component when compared to U.S. interventions. Interventions implemented in the U.S. and internationally resulted in successful outcomes, including positive changes in student BMI. Yet, varying approaches were used to achieve success, reinforcing the fact that a one-size-fits-all approach is not necessary to impact childhood obesity. However, building on successful interventions, future school-based obesity prevention interventions should integrate culturally specific intervention strategies, aim to incorporate an environmental component, and include parents whenever possible. Consideration should be given to the potential impact of long-term, frequent dosage interventions, and subsequent follow-up should be given attention to determine long-term efficacy.

  19. Historical approach of contemporary understanding of school in globalization

    Directory of Open Access Journals (Sweden)

    Parlić-Božović Jasna Lj.

    2015-01-01

    Full Text Available Intercultural education respects and promotes diversity in all areas of human life. This phenomenon indicates that people naturally and spontaneously develop different lifestyles, different customs and worldviews. These differences need to be considered as a wealth of life. When we talk about education, and school as a narrow concept, in which the differences are usually promoted, we have a vision of a community that provides equal opportunities, opposes injustice and discrimination, and strives for the values which equality is being built on. Especially, this phenomenon is being pointed out in our conditions, when we are still adapting to the reforms of globalization. In the Contemporary World, promoting the democracy becomes a key goal of education, as well as the whole society. Therefore, in the education system it should be taken into account the multicultural character of the society that tends to actively contribute to a peaceful coexistence and positive interaction between different cultural groups. Traditionally, in this sense, there are two approaches in education: multi­cultural education that strives to provide the acceptance and tolerance of other cultures through learning about them. On the other side, we have the intercultural education that aims to overcome the passive coexistence and achieve developed and sustainable way of living together in a multicultural society. This is achieved through the construcive process of understanding, mutual respect and dialogue among groups of different cultures, then, ensuring equal opportunities and combating discrimination.

    The basis for the understanding of radioactivity and radioprotection is formed in the secondary school. Therefore, the German-Swiss Radiation Protection Association has been trying to support the appropriate teaching of relevant topics in school for a long time. Unfortunately experiments with radioactive materials are hampered in Germany by complex and confusing legislation. In this contribution the framework is described which is given by the German legislation for the use of radioactive sources in secondary schools. Additionally, proposals for different simple experiments with radioactivity are presented, alternative methods like e.g. virtual experiments are introduced and a recommendation for a simplified regulatory framework is made.

    To assess the characteristics of global experiential and didactic education offerings in the pharmacy curricula. A 2-stage web-based review of US colleges and schools of pharmacy identified country locations of international advanced pharmacy practice experiences (APPE), globally focused didactic courses, and whether these offerings were interprofessional. Schools were contacted to confirm their offerings and were asked about student participation and demand. Sixty-four percent of responding schools confirmed an international APPE offering in 67 different countries with an average graduating class participation of 6.1%. Forty-seven percent of responding schools confirmed a globally focused course offering with an average graduating class participation of 13.1%. Almost two thirds of international APPEs and a majority of courses were designated as interprofessional. Student demand did not outweigh supply for either. Colleges and schools of pharmacy in the United States are continuing to develop global education opportunities for students in the classroom and throughout the world.

    This study aims to develop a training module i-THINK Mathematics Form Two (Mi-T2) to increase the higher-order thinking skills of students. The Mi-T2 training module was built based on the Sidek Module Development Model (2001). Constructivist learning theory, cognitive learning theory, i-THINK map and higher order thinking skills were the building blocks of the module development. In this study, researcher determined the validity and reliability of Mi-T2 module. The design being used in this study was descriptive study. To determine the needs of Mi-T2 module, questionnaires and literature review were used to collect data. When the need of the module was determined, the module was built and a pilot study was conducted to test the reliability of the Mi-T2 module. The pilot study was conducted at a secondary school in North Kinta, Perak. A Form Two class was selected to be the sample study through clustered random sampling. The pilot study was conducted for two months and one topic had been studied. The Mi-T2 module was evaluated by five expert panels to determine the content validity of the module. The instruments being used in the study were questionnaires about the necessity of the Mi-T2 module for guidance, questionnaires about the validity of the module and questionnaires concerning the reliability of the module. Statistical analysis was conducted to determine the validity and reliability coefficients of the Mi-T2 module. The content validity of Mi-T2 module was determined by Cohen's Kappa's (1968) agreement coefficient and the reliability of Mi-T2 module was determined by Cronbach Alpha's value scale. The content validity of Mi-T2 module was 0.89 and the Cronbach Alpha's value of Mi-T2 module was 0.911.

    Dental schools need to produce graduates who are adequately prepared to respond to the complex needs and challenges of the increasingly diverse and interconnected world in which they will practice dentistry. To enhance discussions about the coverage of global oral health competencies in dental education, the aims of this study were to assess how global health education is currently incorporated into predoctoral dental training in the U.S. and which global oral health competencies are being covered. Surveys were emailed to all 64 accredited U.S. dental schools during the 2015-16 academic year. Respondents from 52 schools completed the survey (response rate 81%). The results showed that social determinants of oral diseases and conditions, how to identify barriers to use of oral health services, and how to work with patients who have limited dental health literacy were covered in the greatest number of responding schools' curricula. Key areas of global health curricula that were covered rarely included global dental infrastructure, data collection design, and horizontal and vertical programming approaches to health improvement. Despite current dialogue on the addition of global oral health competencies to dental curricula, only 41% of the responding schools were currently planning to expand their global oral health education. Based on these results, the authors conclude that it may be most feasible for dental schools to add recommended global oral health competencies to their curricula by incorporating didactic content into already established courses.

  6. Global Warming in Schools: An Inquiry about the Competing Conceptions of High School Social Studies and Science Curricula and Teachers

    Science.gov (United States)

    Meehan, Casey R.

    Despite the scientific consensus supporting the theory of anthropogenic (human-induced) global warming, whether global warming is a serious problem, whether human activity is the primary cause of it, and whether scientific consensus exists at all are controversial questions among the U.S. lay-public. The cultural theory of risk perception (Schwarz and Thompson, 1990) serves as the theoretical framework for this qualitative analysis in which I ask the question how do U.S. secondary school curricula and teachers deal with the disparity between the overwhelming scientific consensus and the lay-public's skepticism regarding global warming? I analyzed nine widely used social studies and science textbooks, eight sets of supplemental materials about global warming produced by a range of not-for-profit and governmental organizations, and interviewed fourteen high school teachers who had experience teaching formal lessons about global warming in their content area. Findings suggest: 1) the range of global warming content within social studies and science textbooks and supplemental curricula reflects the spectrum of conceptualizations found among members of the U.S. public; 2) global warming curricula communicate only a narrow range of strategies for dealing with global warming and its associated threats; and 3) social studies and science teachers report taking a range of stances about global warming in their classroom, but sometimes the stance they put forth to their students does not align with their personal beliefs about global warming. The findings pose a troubling conundrum. Some of the global warming curricula treat the cause of global warming--a question that is not scientifically controversial--as a question with multiple and competing "right" answers. At the same time, much of curricula position how we should address global warming--a question that is legitimately controversial--as a question with one correct answer despite there being many reasonable responses

    2011-06-01

    Full Text Available Im schulpädagogischen Diskurs über Heterogenität werden derzeit die unterschiedlichen Voraussetzungen von Lernenden erörtert. Dies betrifft auch das Geschlecht des Schülers und die subjektiven Geschlechterkonstruktionen der Lehrkräfte. Sie neigen oft dazu, im Unterricht geschlechtsstereotypische Erwartungen an die Schüler zu formulieren. In der Heterogenitätsforschung wird jedoch betont, dass Mädchen und Jungen zwar besondere Fähigkeiten besitzen können, es wird aber gleichzeitig auf die Problematik einer geschlechtlich dichotomen Rollenzuschreibung hingewiesen, die einer Gleichwertigkeit in den Bildungschancen entgegengewirkt. Der Aufsatz behandelt Schwerpunkte der schulpädagogischen Geschlechterforschung. Dabei werden die unterschiedlichen Lebensentwürfe von jungen Frauen und Männern im Bildungsprozess vorgestellt und die Koedukation unter dem kritischen Blick auf die geschlechtliche Segregation des Arbeitsmarktes diskutiert.The school pedagogy’s discourse on heterogeneity currently debates the diverse conditions of learners. This also regards the gender of pupils and the subjective constructions of gender roles by teachers. During lessons, teachers often tend to formulate expectations of gender-stereotypical behaviour to their pupils. Yet, in the research of heterogeneity, it is stressed that girls and boys may indeed possess different skills and abilities but at the same time the problem of a dichotomous role ascription to both genders is pointed out which counteracts equality of educational opportunities. The paper deals with three foci of the school pedagogy’s gender research. The different life courses of young women and men in the process of their education is depicted. Co-education is critically examined with regard to the gender segregation of the employment market.

  15. A rural math, science, and technology elementary school tangled up in global networks of practice

    Science.gov (United States)

    Carlone, Heidi B.; Kimmel, Sue; Tschida, Christina

    2010-06-01

    This is an ethnographic study of a newly created math, science, and technology elementary magnet school in a rural community fiercely committed to cultural preservation while facing unprecedented economic instability brought on by massive loss of manufacturing jobs. Our goal was to understand global- and community-level contexts that influenced the school's science curriculum, the ways the school promoted itself to the community, and the implicit meanings of science held by school staff, parents and community members. Main sources of data were the county's newspaper articles from 2003 to 2006, the school's, town's, and business leaders' promotional materials, and interviews with school staff, parents, and community members. A key finding was the school's dual promotion of science education and character education. We make sense of this "science with character" curriculum by unpacking the school and community's entanglements with historical (cultural preservation), political (conservative politics, concerns for youth depravity), and economic (globalization) networks. We describe the ways those entanglements enabled certain reproductive meanings of school science (as add-on, suspect, and elitist) and other novel meanings of science (empathetic, nurturing, place-based). This study highlights the school as a site of struggle, entangled in multiple networks of practice that influence in positive, negative, and unpredictable ways, the enacted science curriculum.

    Energy Technology Data Exchange (ETDEWEB)

    Rogall, Holger

    2014-07-01

    This book presents itself as a systematic, easily understandable introduction into the requirements for an energy supply based 100% on renewable energy. Its main focus is on the strategic paths that must be followed for this purpose in the realms of business, technology and governmental policy. It highlights the opportunities and impediments on the way, analysing in the process the roles of political, economic and civil society players from the global down to the municipal level. Starting out from the present state of discussion on the German energy transition it investigates the strengths and weak points of efficiency technologies and renewable energies available today and elaborates a strategic path for developing the necessary infrastructure. In awareness of the fact that 100% coverage will not come about from market mechanisms alone it explores the ecological crash barriers that need to be set up in addition. This is followed by chapters on the roles, interests and means of those players who can exert influence on the framing of the relevant political and legal instruments as well as their means of pursuing their interests. The book thus contributes to clarifying the possibilities of and impediments to achieving an energy supply system based 100% on renewable energy.

    Global health has become an increasingly important focus of education, research, and clinical service in North American universities and academic health centers. Today there are at least 49 academically based global health programs in the United States and Canada, as compared with only one in 1999. A new academic society, the Consortium of Universities for Global Health, was established in 2008 and has grown significantly. This sharp expansion reflects convergence of 3 factors: (1) rapidly growing student and faculty interest in global health; (2) growing realization–powerfully catalyzed by the acquired immune deficiency syndrome epidemic, the emergence of other new infections, climate change, and globalization–that health problems are interconnected, cross national borders, and are global in nature; and (3) rapid expansion in resources for global health. This article examines the evolution of the concept of global health and describes the driving forces that have accelerated interest in the field. It traces the development of global health programs in academic health centers in the United States. It presents a blueprint for a new school-wide global health program at Mount Sinai School of Medicine. The mission of that program, Mount Sinai Global Health, is to enhance global health as an academic field of study within the Mount Sinai community and to improve the health of people around the world. Mount Sinai Global Health is uniting and building synergies among strong, existing global health programs within Mount Sinai; it is training the next generation of physicians and health scientists to be leaders in global health; it is making novel discoveries that translate into blueprints for improving health worldwide; and it builds on Mount Sinai’s long and proud tradition of providing medical and surgical care in places where need is great and resources few.

    2013-10-01

    In this study, 491 dental students at one dental school in the United States and one in Bulgaria were surveyed to assess their perceptions about the mission of dental schools to advance global dentistry and philanthropy. The study included questions about prior involvement in charitable dental missions. Many respondents felt that their dental school does not advance global dentistry nor adequately teaches students the virtues of philanthropy and volunteerism. The majority agreed, however, that dental schools have a moral obligation to raise the level of oral health care worldwide and help underserved communities access basic dental care. They reported that an opportunity to spend a semester at a foreign dental school would enhance their dental education in ways that are not presently fulfilled; help them better understand cultural diversity; and teach them about philanthropy and volunteerism. In their opinion, international exchange programs that provide clinical rotations and field experiences in economically challenged and underserved areas of the world would a) foster the global advancement of dentistry; b) promote an appreciation for cultural diversity and socioeconomic disparity in the communities that graduates will be serving; and c) teach students the virtues of philanthropy and volunteerism. This study may contribute to understanding factors affecting student involvement in programs to advance global dentistry.

  6. Should we establish a North American school of global health sciences?

    Hotez, Peter J

    2004-08-01

    Since 1997, an unprecedented amount of American philanthropy from both private and federal sources has been directed toward research and control programs for the major tropical infectious diseases of developing countries. The US and Canadian capacity to respond to these new initiatives might prove inadequate, however, as tropical disease research and training infrastructures have deteriorated at most North American academic health centers over the last three decades. Training opportunities in clinical tropical medicine, parasitology laboratory diagnostics, vector control, and public health practice are especially depleted and portend a lost generation of experts in these areas. In addition, unlike some of the European schools of tropical medicine, no North American medical or public health school currently boasts a comprehensive faculty in the global health sciences, with expertise that spans laboratory investigation, clinical and translational research, health policy, and international development. To meet the challenge presented by the new philanthropy targeting the global diseases of poverty, a North American school of global health sciences should be established. The North American school, possibly in association with one of the existing schools of medicine or public health, would provide interdisciplinary training to produce a new generation of global health scientists.

    Full Text Available In the context of globalization of the business education market, Russian business schools face a complex managerial problem - how to preserve a business school's identity. The parameters of demand for managerial education in Russia have become significantly more complicated, new global competitive pressure forces have arisen, compelling business schools to adjust and revise their strategies and comply with international standards of the global business education market. Normative pressure is one of the key reasons that encourage business schools to adapt successful overseas education models. However, the impact of market logic often covers normative appeals to adaptation, as reflected in copying and adoption of the US MBA model. Our research aims to show what the priorities of Russian business school MBA students are today in choosing a business school, as well as which of the competencies of graduates are most on demand in the Russian labour market. The research was conducted over a period of three years (from 2014 to 2016, 358 Lomonosov Moscow State University MBA program graduates who study in Russia and Kazakhstan participated in our questionnaires. The structure of qualities stated by our graduates raises serious challenges to the content and standards of MBA programs in the global context, especially considering the cultural code of the nation, manifested in the practice of doing business. Globalized and marketable specialized managerial knowledge is clearly a priority among graduates today. Greater attention is being devoted to new innovative models in the field of managerial education (edtech platforms, on-demand platforms, subscription model, freemium model, etc.. The development of innovative models by traditional business schools may cause tension between efficiency and innovation as well as conflicting managerial tasks. Among strategic priorities for Russian business schools under the influence of globalization we highlight

The subjects were 111 teachers from 7 elementary schools in Yogyakarta City and Sleman district. The data were collected using open-ended questions (including perception about the weather, feeling evoked by global warming words and free responses related to global warming issues. The data were analyzed using the technique of qualitative and quantitative content analysis with Indigenous Psychology Approach. The result showed that only one teacher reported that there was no weather anomaly, while 110 teachers reported that they perceived weather anomaly. Of those who perceived weather anomaly mostly referred to natural conditions (including global climatic condition and environmental destruction and human behavior as its causes. Responses about feeling as evoked by global warming word were classified into three categories, i.e. emotional, physical and irrelevant responses. Free responses about global warming were classified into four categories respectively from the highest frequency of responses: prevention (including statement “must be prevented”, prevention behaviors and prevention efforts, states (including the weather states and feeling, causes (including technological advances and human behavior generally, and others. The research finding was discussed in the frame of environmental concern as a means of character education in elementary school.

    The conceptual design of the MIT modular pebble bed reactor is described. This reactor plant is a 250 Mwth, 120 Mwe indirect cycle plant that is designed to be deployed in the near term using demonstrated helium system components. The primary system is a conventional pebble bed reactor with a dynamic central column with an outlet temperature of 900 C providing helium to an intermediate helium to helium heat exchanger (IHX). The outlet of the IHX is input to a three shaft horizontal Brayton Cycle power conversion system. The design constraint used in sizing the plant is based on a factory modularity principle which allows the plant to be assembled 'Lego' style instead of constructed piece by piece. This principle employs space frames which contain the power conversion system that permits the Lego-like modules to be shipped by truck or train to sites. This paper also describes the research that has been conducted at MIT since 1998 on fuel modeling, silver leakage from coated fuel particles, dynamic simulation, MCNP reactor physics modeling and air ingress analysis.

    Full Text Available Global health is increasingly present in the formal educational curricula of medical schools across North America. In 2008, students at Johns Hopkins University School of Medicine (JHUSOM perceived a lack of structured global health education in the existing curriculum and began working with the administration to enhance global health learning opportunities, particularly in resource-poor settings. Key events in the development of global health education have included the introduction of a global health intersession mandatory for all first-year students; required pre-departure ethics training for students before all international electives; and the development of a clinical global health elective (Global Health Leadership Program, GHLP. The main challenges to improving global health education for medical students have included securing funding, obtaining institutional support, and developing an interprofessional program that benefits from the resources of the Schools of Medicine, Public Health, and Nursing. Strategies used included objectively demonstrating the need for and barriers to more structured global health experiences; obtaining guidance and modifying existing resources from other institutions and relevant educational websites; and harnessing institution-specific strengths including the large Johns Hopkins global research footprint and existing interprofessional collaborations across the three schools. The Johns Hopkins experience demonstrates that with a supportive administration, students can play an important and effective role in improving global health educational opportunities. The strategies we used may be informative for other students and educators looking to implement global health programs at their own institutions.

    Full Text Available It is a cliché, but also a fundamental fact that we live in a world where globalization and international challenges, opportunities and relationships play an increasing role. However, how have these changing conditions affected the content of school history? To what degree have curricula and textbooks addressed these challenges? Is the main focus in school history still on the history of the nation state, or has it successfully integrated topics and themes from world history? These are questions I discuss in this paper. In the main, my starting point is the situation in Denmark, but with perspectives and comparisons from Norway, England and Germany. Among other things, I will put school history in a historical context, because the subject’s history and genesis—in my opinion—tends to maintain a traditional content and form of organization, thereby reducing the subject’s usefulness. At the end of the paper, I outline and discuss a few alternative options for selecting and organizing the content with the aim of being more inclusive with regard to global and international aspects. The paper must be understood as a step towards the clarification of a development project that aims to propose and experiment with practices for the selection and organization of the content of the history curriculum, with the aim of increasing the international and global dimensions in history teaching.

  6. Globalization and Classroom Practice: Insights on Learning about the World in Swedish and Australian Schools

    2013-08-01

    Full Text Available Globalization and global education implies changes to practices at the classroom level to adapt to new imperatives associated with technology use and awareness, and environmental sustainability. It also implies much more. It implies that teachers apply their classroom pedagogy to take account of students’ new found global understandings of which they, and the school community, is largely unaware. This article addresses and discuses three key consequences of globalization for classrooms worldwide; an increased diversity of experience of the students within the classroom, an increased competitiveness of educational outcomes between national states and subsequently some standardisation of curriculum across nations to enable this, and an increased emphasis on teaching skills and values associated with intercultural understanding. Young children’s map knowledge and their resultant, and associated, interpretations of the world from a comparative study a from Swedish and Australian primary classrooms is used as examples of some of these implications of the impact of ‘global culture’ and ‘global issues’ on current and future classroom practice.

    Full Text Available Ecological approaches have highlighted the importance of the built environment as a factor affecting physical activity. However, knowledge on children's activity patterns is still incomplete. Particularly, data on the spatial context of physical activity is limited, which limits the potential to design location-based interventions effectively. Using global positioning system (GPS and accelerometry, this study aimed to identify locations where children engage in moderate-vigorous physical activity (MVPA.Participants included 119 children (11-14 years, 57% girls from public schools in Winterthur, Switzerland. During a regular school week between February and April 2013, children wore an accelerometer and GPS sensor for seven consecutive days. Time-matched accelerometer and GPS data was mapped with a geographic information system and each data point was assigned to one of seven defined activity settings. Both the absolute amount of MVPA and proportion of time in MVPA were calculated for every setting. Multilevel analyses accounting for the hierarchical structure of the data were conducted to investigate any gender differences.Children achieved most MVPA on streets (34.5% and on school grounds (33.4%. The proportion children spent in MVPA was highest in recreational facilities (19.4%, at other schools (19.2% and on streets (18.6%. Boys accumulated significantly more MVPA overall and on other school grounds (p < 0.05 and showed a significantly higher proportion of time in MVPA at own school and outside of Winterthur (p < 0.05.The results indicate the importance of streets and school grounds as activity-promoting environments. The high use of streets may be an indicator for active transportation, which appears to contribute to an active lifestyle in both genders. In contrast, the school setting is more likely to encourage physical activity in boys. Recreational facilities seem to be conducive for MVPA among both genders, although infrequently visited

    A NASA-funded Innovations in Climate Education (NICE) Program has been launched in Alabama to improve high school and middle school education in climate change science. The overarching goal is to generate a better informed public that understands the consequences of climate change and can contribute to sound decision making on related issues. Inquiry based NICE modules have been incorporated into the existing course of study for 9-12 grade biology, chemistry, and physics classes. In addition, new modules in three major content areas (earth and space science, physical science, and biological science) have been introduced to selected 6-8 grade science teachers in the summer of 2013. The NICE modules employ five E's of the learning cycle: Engage, Explore, Explain, Extend and Evaluate. Modules learning activities include field data collection, laboratory measurements, and data visualization and interpretation. Teachers are trained in the use of these modules for their classroom through unique partnership with Alabama Science in Motion (ASIM) and the Alabama Math Science Technology Initiative (AMSTI). Certified AMSTI teachers attend summer professional development workshops taught by ASIM and AMSTI specialists to learn to use NICE modules. During the school year, the specialists in turn deliver the needed equipment to conduct NICE classroom exercises and serve as an in-classroom resource for teachers and their students. Scientists are partnered with learning and teaching specialists and lead teachers to implement and test efficacy of instructional materials, models, and NASA data used in classroom. The assessment by professional evaluators after the development of the modules and the training of teachers indicates that the modules are complete, clear, and user-friendly. The overall teacher satisfaction from the teacher training was 4.88/5.00. After completing the module teacher training, the teachers reported a strong agreement that the content developed in the NICE

    This study investigates the unique contribution of microsocial and global measures of parent-child positive coregulation (PCR) in predicting children's behavioral and social adjustment in school. Using a community sample of 102 children, ages 4-6, and their parents, we conducted nested path analytic models to identify the unique effects of 2 measures of PCR on school outcomes. Microsocial PCR independently predicted fewer externalizing and inattention/impulsive behaviors in school. Global PCR did not uniquely relate to children's behavioral and social adjustment outcomes. Household socioeconomic status was related to both microsocial and global measures of PCR, but not directly associated with school outcomes. Findings illustrate the importance of using dynamic measures of PCR based on microsocial coding to further understand how the quality of parent-child interaction is related to children's self-regulatory and social development during school transition.

    Full Text Available The paper aims to investigate potential tensions between local and global context of contemporary ruralities, emphasizing the times, rhythms and spaces constructed from the experiences of teachers and students in the organization of the routines of rural schools. The paper presents theoretical considerations resulting from two studies in the Graduate Program in Education and Contemporary - PPGEduC / UNEB. The clipping and analysis undertaken focus on education developed in rural areas and tensions present in this context in view, discuss issues concerning the new ruralities contemporary. This discussion has as its central theme the issues of timing and the rhythm in schools with multigrade classes Island Tide that articulates with dilemmas and tensions surrounding the experience lived by teachers of geography of the city engaged in teaching in rural areas in semi-arid region of Bahia. Research has pointed to difficulties faced by rural school to consider the different temporalities that exist in rural areas in their educational processes, as well as difficulties of articulation in these contexts of learning, between the local-global dimensions through which passes the contemporary space. This movement creates stress for teachers’ work, since it complicates the relationship between the times established, standardized and rigid, with times of personal students and teachers, covering aspects such as age, life histories, movements and experiences socio-historical and geographical subjects involved in the processes of teaching and learning in rural settings in contemporary times.

    Full Text Available With the rapid development of WLAN, more and more schools and businesses have begun to provide the WLAN for users. However, WLAN is considerably more susceptible to MitM (man- in-the-middle attack. To overcome it, we propose a dynamic password technology named Two-way Dynamic Authentication Technology (TDAT. It uses two-factor during the initial authentication, and uses a two-way hash chain during the cross-domain authentication. TDAT effectively protects users' authentication credentials and improves users' experience. In an actual wireless network environment, we implement a MitM attack framework based on Rogue AP. Then we effectively prevent this MitM attack by using TDAT. Moreover we analyze the security of TDAT by using BAN logic.

Ninehundred eightytwo consecutive patients, undergoing total thyroidectomy, were enrolled. The thyroid volume and maximal nodule diameter were measured by means of ultrasounds. Based on ultrasounds findings, patients were divided into three groups: minimally invasive video assisted thyroidectomy (MIVAT), minimally invasive thyroidectomy (MIT) and conventional thyroidectomy (CT) groups. The data concerning the following parameters were collected: operative time, postoperative complications, postoperative pain and cosmetic results. The MIVAT group included 179 patients, MIT group included 592 patients and CT group included 211 patients. Incidence of complications did not differ significantly in each group. In MIVAT and MIT group, the perception of postoperative pain was less intense than CT group. The patients in the MIVAT (7±1.5) and MIT (8±2) groups were more satisfied with the cosmetic results than those in CT group (5±1.3) (p= MIT is a technique totally reproducible, and easily convertible to perform surgical procedures in respect of the patient, without additional complications, increased costs, and with better aesthetic results.

    Jupiter's upper atmospheric temperature is considerably higher than that predicted by Solar Extreme Ultraviolet (EUV) heating alone. Simulations incorporating magnetosphere-ionosphere coupling effects into general circulation models have, to date, struggled to reproduce the observed atmospheric temperatures under simplifying assumptions such as azimuthal symmetry and a spin-aligned dipole magnetic field. Here we present the development of a full three-dimensional thermosphere model coupled in both hemispheres to an axisymmetric magnetosphere model. This new coupled model is based on the two-dimensional MIT model presented in Yates et al., 2014. This coupled model is a critical step towards to the development of a fully coupled 3D MIT model. We discuss and compare the resulting thermospheric flows, energy balance and MI coupling currents to those presented in previous 2D MIT models.

    This aim of this research was to investigate primary school science teachers understanding and teaching practice as well as the influence on teaching and learning a topic like global warming. The participants were four primary science teachers, who were not graduated in science education. Methodology was the case study method, which was under the qualitative research regarded from interpretive paradigm. Data were collected by openended questionnaire, semi-structure interview, and document colleting. The questionnaire examined teachers' background, teachers' understanding of problems and threats of science teaching, desiring of development their PCK, sharing the teaching approaches, and their ideas of strength and weakness. a semi-structured interview was conducted based on the approach for capturing PCK of Loughran [23] content representation (CoRe). And, the document was collected to clarify what evidence which was invented to effect on students' learning. These document included lesson plan, students' task, and painting about global warming, science projects, the picture of activities of science learning, the exercise and test. Data analysis employed multiple approach of evidence looking an issue from each primary science teachers and used triangulation method to analyze the data with aiming to make meaning of teachers' representation of teaching practice. These included descriptive statistics, CoRe interpretation, and document analysis. The results show that teachers had misunderstanding of science teaching practice and they has articulated the pedagogical content knowledge in terms of assessment, goal of teaching and linking to the context of socio cultural. In contrast, knowledge and belief of curriculum, students' understanding of content global warming, and strategies of teaching were articulated indistinct by non-graduate science teacher.

Experten verschiedener Fachgesellschaften aus Deutschland, Österreich und der Schweiz haben nun einen aktuellen Konsens der Kompressionstherapie für Patienten mit Ulcus cruris venosum erstellt. In Europa ist das Ulcus cruris venosum eine der häufigsten Ursachen für chronische Wunden. Neben der konservativen und interventionellen Wund- und Venentherapie, ist die Kompressionstherapie die Basis der Behandlungsstrategien. Die Kompressionstherapie kann heute mit sehr unterschiedlichen Materialien und Systemen durchgeführt werden. Während in der Entstauungsphase insbesondere Verbände mit Kurzzugbinden oder Mehrkomponentensysteme zur Anwendung kommen, sind es anschließend überwiegend Ulkus-Strumpfsysteme. Eine weitere, bislang wenig verbreitete Alternative sind adaptive Kompressionsbandagen. Insbesondere für die Rezidivprophylaxe werden medizinische Kompressionsstrümpfe empfohlen. Durch die Vielzahl der heute zur Verfügung stehenden Behandlungsoptionen, kann für nahezu alle Patienten ein Konzept entwickelt werden, dass sich an den individuellen Bedürfnissen und Fähigkeiten orientiert und daher auch akzeptiert und durchgeführt wird. Die Kompressionstherapie ist für die Behandlung von Patienten mit Ulcus cruris venosum essentiell. In den letzten Jahren sind viele verschiedene Therapieoptionen verfügbar, die in den deutschsprachigen Ländern unterschiedlich angewendet oder durchgeführt werden. Daher soll dieser Expertenkonsens dazu beitragen, konkrete Empfehlungen für die praktische Durchführung der Kompressionstherapie von Patienten mit Ulcus cruris venosum darzustellen. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

    Investigating the chemical composition of the atmosphere and its influence on the global climate involves a large number of trace species. Therefore, the Lagrangian transport scheme ATTILA has been developed in this thesis. ATTILA runs online in the general circulation model ECHAM4 and, thus, can be used efficiently for studies involving many tracers. The present study discusses the problems which arise when applying Lagrangian methods on long range and global scale, and describes in detail the solutions developed for ATTILA. Transport experiments with both short-lived and long-lived tracers clearly show that ATTILA is numerically much less diffusive than the operational semi-Lagrangian scheme of ECHAM. It could be shown that the enhanced meridional transport in the tropopause region and the overestimated downward flux through the tropopause in ECHAM are rather due to the numerical properties of the semi-Lagrangian scheme than due to an incorrect circulation. Furthermore, the stratospheric dynamics has been investigated in this study by analysing trajectories and by calculating age spectra and mass fluxes. (orig.)

The DSCT and MR images were evaluated: end-systolic (ESV), end-diastolic LV (EDV) volumes, stroke volume (SV), ejection fraction (EF), and myocardial mass (MM) as well as LV wall thickening and segmental WM applying the AHA model were obtained and statistically analyzed. Results: The mean LV-EDV (r = 0.96) and ESV (r = 0.98) as well as LV-EF (r = 0.97), SV (r = 0.83), and MM (r = 0.95) correlated well. Bland Altman analysis revealed little systematic underestimation of LV-EF (-1.1 {+-} 7.8%), EDV (-0.3 {+-} 18.2 ml), SV (-1.3 {+-} 16.7 ml) and little overestimation of ESV (1.1 {+-} 7.8 ml) and MM (12.8 {+-} 14.4 g) determined by DSCT. Systolic reconstruction time points correlated well (DSCT 32.2 {+-} 6.7 vs. MRI 35.6 {+-} 4.4% RR-interval). The LV wall thickness obtained by DSCT and MRI showed close correlation in all segments (diameter diff 0.42 {+-} 1 mm). In 413 segments (89%) WM abnormalities were equally rated, whereas DSCT tended to underestimate the degree of wall motion impairment. Conclusion: DSCT with optimized temporal resolution enables regional and global LV function analysis as well as segmental WM analysis in good correlation with MRI. However, the degree of WM impairment is slightly underestimated by DSCT. (orig.)

    Full Text Available Die paradigmatische Unterscheidung zwischen Sozial- und Kulturwissenschaften, die spätestens seit den 1980er Jahren eingehend diskutiert wurde, lässt sich anhand des Bereichs des Symbolischen auf den Punkt bringen: Ist das Symbolische nur ein Effekt von sozialen, ökonomischen oder medialen Strukturen einer gegebenen Gesellschaft oder reproduzieren sich Strukturen nur durch die symbolischen Handlungen der AkteurInnen innerhalb einer gegebenen Kultur? So hatte etwa der klassische "harte" Strukturalismus bei Claude Lévi-Strauss, Jacques Lacan und dem frühen Michel Foucault symbolische Ordnungen (und d. i. hier die Sprache als eine unbewusst determinierende Voraussetzung von menschlicher Interaktion begriffen, woraufhin mit dem Post- bzw. Neostrukturalismus die Rückkehr der individuellen Äußerung, der parole, des speech acts (und d. i. hier das Sprechen, also der symbolischen Handlung in den Mittelpunkt rückte. Medienpädagogisch ist diese Unterscheidung gerade dann von Interesse, wenn es darum geht, wie Lehrende und Lernende sich zueinander verhalten, interagieren und dabei eben mit Symbolen handeln. Insofern ist es bemerkenswert, dass – fast parallel zu Foucaults Unterscheidung von diskursiven und nicht-diskursiven Praktiken – auch Dieter Baacke 1973 von diskursiven und nicht-diskursiven Symbolen gesprochen hat. Denn – wie auch im Rahmen des "Symbolischen Interaktionismus" von George Herbert Mead argumentiert wurde – können Symbole nur im Rahmen einer gegebenen Diskursökonomie von AkteurInnen diskursiv ausgetauscht werden und konstituieren dabei Erfahrungen bzw. Wahrnehmungen und somit auch die soziale bzw. kulturelle Wirklichkeit. Insofern ist die Frage nach dem Symbolischen immer auch eine Frage nach den Möglichkeiten der Handlungstheorie (im Sinne Jürgen Habermas’ bzw. der Praxeologie (im Sinne Pierre Bourdieus.

  5. Grundlegende Steuerungsverfahren im heterogenen Logistiknetz mit Kanban

    In vielen Unternehmen werden heterogene (verschiedene) Steuerungen in einem abgestimmten Konzept kombiniert. Je nach Anwendungsfall und Rahmenbedingungen werden Kombinationen allgemein bekannter Steuerungen oder Steuerungsvarianten gemischt eingesetzt, um eine optimale Steuerung für unterschiedliche Fälle zu erreichen. Hierbei stehen neben den bekannten und weit verbreiteten Methoden, wie Material Requirements Planning (MRP) oder Kanban, auch weniger bekannte oder neue Methoden zur Auswahl, wie die Produktionssteuerung mit dezentraler, bestandsorientierter Fertigungsregelung (DBF). Kanban ist ein simples und effizientes Steuerungskonzept, das in der klassischen Form für spezifische einfache Anwendungsfälle umsetzbar ist. Hochentwickelte Steuerungsalgorithmen können helfen, komplexe Abläufe optimal abzubilden. Mit einer grundlegenden Vereinfachung der Abläufe kann allerdings in vielen Fällen ein wesentlich stärkerer und umfassender Verbesserungseffekt erzielt werden. Die wesentliche Fragestellung sollte folglich lauten: Warum ist der Ablauf nicht mit einer einfachen Steuerung wie Kanban abzubilden? Um die Vorteile des Konzepts auch in untypischen Bereichen anwenden zu können, sind jedoch verschiedene Varianten oder Kanban-ähnliche Steuerungsmethoden entstanden. Darüber hinaus sind in der Praxis hybride Steuerungen im Einsatz, welche so kombiniert werden, dass die Zusammensetzung anspruchsvolle Eigenschaftsbilder noch exakt abbildet. In der Praxis basieren die Steuerungsentscheidungen nur zu einem kleinen Teil auf den eigentlichen Steuerungsalgorithmen, wie sie uns das MRP-System zur Verfügung stellt. Moderne Steuerungswelten" schließen alle relevanten Informationsquellen in eine heterogene Entscheidungsmatrix mit ein. Letztlich zählt nicht, ob die Entscheidung auf den Informationen aus dem MRP-System oder auf Softfacts basierend getroffen wurde, sondern nur, ob die Entscheidung erfolgreich war.

    In 2007 and 2012, the Global School-Based Student Health Survey (GSHS) and the Global Youth Tobacco Survey (GYTS) were implemented to estimate the prevalence of risk behaviors and protection factors among 13 to 15 year-old adolescents. To assess changes in dietary, body weight, tobacco and physical activity indicators in the past five years. Cross-sectional study. A randomized, two-stage sampling with 600 schools selected at a national level was used. Students from randomly selected courses were invited to answer a self-administered questionnaire (either the GSHS or the GYTS). In 2012, the GSHS was completed by 20 697 students from 544 schools, while the GYTS was completed by 2062 students from 73 schools. Between 2007 and 2012, overweight and obesity prevalence significantly increased (overweight: 24.5% in 2007, 28.6% in 2012; obesity 4.4% in 2007, 5.9% in 2012), while the consumption of sugar-sweetened beverages and fast food remained high. A slight improvement was observed in the level of physical activity (12.7% in 2007, 16.7% in 2012), although it remains below what is recommended. The prevalence of tobacco use was reduced (24.5% in 2007, 19.6% in 2012), but access to tobacco products and exposure to secondhand smoke remains high in public places, including schools. The spread of the overweight and obesity epidemic calls for a need to consolidate actions tending towards a healthy diet and physical activity. Despite a decrease in the prevalence of tobacco use, it is necessary to continue strengthening tobacco control actions.

    Education and training in human rights has been set as a priority by the United Nations. Health and human rights are closely related. Training professionals from various backgrounds in human rights might ultimately contribute to improve the health of individuals and communities. We present the 5 years' experience with a 3-week residential Global Health and Human Rights Course developed at the University of Geneva and implemented with the support/participation of international organizations (IOs) and non-governmental organizations active in the health and human rights sector. Over the years, roughly 150 students from 43 nationalities, with many different educational backgrounds, attended the course. The male/female ratio was 1/5. The adopted educational approach was multifold and comprised lectures from academics and experts with field experience, group work, individual case studies, journal clubs, and site visits. Evaluation data show that site visits at IOs were highly appreciated as well as networking opportunities among students, with academics and experts with field experience. The variety of topics discussed was, at times, "too much"; yet, it allowed students to measure the extent of the challenges the field is facing. The adopted active learning approach facilitated the exchange of experiences among students and allowed them to get acquainted with different cultural sensitivities. The Global Health and Human Rights Summer-School of the University of Geneva allowed its participants, coming from all over the world, to identify challenges of the interlinked fields of health and human rights, reflect upon their underlying causes, and imagine possible solutions. Sharing our experience will hopefully help passionate educators around the world to develop similar programs.

    Science.gov (United States)

    Golden, Barry W.

    This research examined middle school student conceptions about global climate change (GCC) and the change these conceptions undergo during an argument driven instructional unit. The theoretical framework invoked for this study is the framework theory of conceptual change (Vosniadou, 2007a). This theory posits that students do not simply correct incorrect ideas with correct ones, but instead weigh incoming ideas against already existing explanatory frameworks, which have likely served the learner well to this point. The research questions were as follows: (1) What are the patterns of students' conceptual change in GCC? (a) What conceptions are invoked in student learning in this arena? (b) What conceptions are most influential? (c) What are the extra-rational factors influencing conceptual change in GCC? This research took place in an urban public school in a medium sized city in the southeastern United States. A sixth grade science teacher at Central Middle school, Ms. Octane, taught a course titled "Research Methods I., which was an elective science course that students took as part of a science magnet program. A unit was designed for 6th grade instruction that incorporated an Argument-Driven Inquiry (ADI) approach, centered on the subject matter of Global Climate change and Global Warming. Students were immersed in three separate lessons within the unit, each of which featured an emphasis upon creating scientific explanations based upon evidence. Additionally, each of the lessons placed a premium on students working towards the development of such explanations as a part of a group, with an emphasis on peer review of the robustness of the explanations proposed. The students were involved in approximately a two week unit emphasizing global climate change. This unit was based on an argumentation model that provided data to students and asked them to develop explanations that accounted for the data. The students then underwent a peer-review process to determine if

    Massachusetts Institute of Technology (MIT) partnered with the U.S. Department of Energy (DOE) to develop and implement solutions to retrofit existing buildings to reduce energy consumption by at least 30% as part of DOE’s Commercial Building Partnerships (CBP) Program.1 Lawrence Berkeley National Laboratory (LBNL) provided technical expertise in support of this DOE program. MIT is one of the U.S.’s foremost higher education institutions, occupying a campus that is nearly 100 years old, with a building floor area totaling more than 12 million square feet. The CBP project focused on improving the energy performance of two campus buildings, the Ray and Maria Stata Center (RMSC) and the Building W91 (BW91) data center. A key goal of the project was to identify energy saving measures that could be applied to other buildings both within MIT’s portfolio and at other higher education institutions. The CBP retrofits at MIT are projected to reduce energy consumption by approximately 48%, including a reduction of around 72% in RMSC lighting energy and a reduction of approximately 55% in RMSC server room HVAC energy. The energy efficiency measure (EEM) package proposed for the BW91 data center is expected to reduce heating, ventilation, and air-conditioning (HVAC) energy use by 30% to 50%, depending on the final air intake temperature that is established for the server racks. The RMSC, an iconic building designed by Frank Gehry, houses the Computer Science and Artificial Intelligence Laboratory, the Laboratory for Information and Decision Systems, and the Department of Linguistics and Philosophy.

    Education is important in improving economies and creating literate, self-reliant and healthy societies. However, hunger is a barrier to basic education in Malawi. Hunger is also associated with a number of health risk behaviours, such as bullying, suicide ideation and unhygienic behaviours that may jeopardize the future of children. There are, however, limited data on the prevalence and associated factors of hunger among school children in Malawi. The study used data from the Malawi Global School-Based Health Survey conducted in 2009 to estimate the prevalence of self-reported hunger within the last 30 days among primary and secondary school age group. It also assessed the association between self-reported hunger and some selected list of independent variables using frequency distribution, chi-squared test and logistic regression. A total of 2359 students were available for analysis. The overall self-reported prevalence of hunger within the last 30 days was 12.5% (18.9% (172) in the rural and 8.3% (115) in urban areas; and 11.9%(123) for male and 12.5(148) for female children). In the final analysis, geographical location, eating fruits, having been bullied, suicide ideation, and washing hands with soap were significantly associated with hunger. Hunger in both primary and secondary school children in Malawi is a major social problem. The design of school feeding programmes aimed to reduce hunger should incorporate the factors identified as associated with hunger.

    A case of Graves` disease occurring in a patient with hemiagenesis is presented. The detection of the rare occurrence of a congential hemiagenesis is often made by either clinical symptoms of thyroid dysfunction or anatomical abnormalities such as nodular goiter. The symptoms of hyperthyroidism in the current case led to the diagnostic confirmation by scintiscanning and ultrasonography of an absent lobe. Anti-thyroid antibody studies documented the presence of Graves` disease within the remaining lobe. (orig.) [Deutsch] Die Hemiagenesie der Schilddruese stellt eine seltene angeborene Veraenderung dar.

    Climate change is a consequence of interaction among the biosphere, atmosphere, hydrosphere and geosphere. The causes of climate change are extremely complicated for scientists to explain. The fact that the global climate has kept warming in the past few decades is one example. It remains controversial for scientists whether this warming is the result of human activity or natural causes. This research aims to lead students to discuss the causes of global warming from distinct and controversial viewpoints to help the students realize the uncertainty and complicated characteristics of the global warming issue. The context of applying the critical thinking model to teaching the scientific concepts of climate change and global warming is designed for use in junior high schools. The videos of the upside concept 'An Inconvenient Truth' (a 2006 documentary film directed by Davis Guggenheim) and the reverse-side concept 'The Great Global Warming Swindle' (a 2007 documentary film made by British television producer/director Martin Durkin) about the global warming crisis are incorporated into lessons in order to guide students to make their own decisions appropriately when discussing the earth climate change crisis. A questionnaire, individual teacher interviews and observations in class were conducted to evaluate the curriculum. The pre-test and post-test questionnaires showed differences in the students' knowledge, attitudes and behavior towards the global warming phenomenon before and after attending the lessons. The results show that those students who attended the whole curriculum had a significant increase in their knowledge and behavior factors of global climate (P value <0.001*). However, there was no significant improvement in their attitudes between the pre-test and post-test questionnaires (P value=0.329). From the individual interviews, the teachers who gave the lessons indicated that this project could increase the interaction with their students during class

  11. Conceptual Change regarding middle school students' experience with Global Climate Change

    2011-12-01

    Given the complexity of the science involving climate change (IPCC, 2007), its lack of curricular focus within US K-12 schooling (Golden, 2009), and the difficulty in effecting conceptual change in science (Vosniadou, 2007), we sought to research middle school students' conceptions about climate change, in addition to how those conceptions changed during and as a result of a deliberately designed global climate change (GCC) unit. In a sixth grade classroom, a unit was designed which incorporated Argumentation-Driven Inquiry (Sampson & Grooms, 2010). That is, students were assigned to groups and asked to make sense of standard GCC data such as paleoclimate data from ice cores, direct temperature measurement, and Keeling curves, in addition to learning about the greenhouse effect in a modeling lesson (Hocking, et al, 1993). The students were then challenged, in groups, to create, on whiteboards, explanations and defend these explanations to and with their peers. They did two iterations of this argumentation. The first iteration focused on the simple identification of climate change patterns. The second focused on developing causal explanations for those patterns. After two rounds of such argumentation, the students were then asked to write (individually) a "final" argument which accounted for the given data. Interview and written data were analyzed prior to the given unit, during it, and after it, in order to capture complicated nuance that might escape detection by simpler research means such as surveys. Several findings emerged which promised to be of interest to climate change educators. The first is that many students tended to "know" many "facts" about climate change, but were unable to connect these disparate facts in any meaningful ways. A second finding is that while no students changed their entire belief systems, even after a robust unit which would seemingly challenge such, each student engaged did indeed modify the manner in which they discussed the

    Phase I trial designed to determine the maximum tolerable dose to normal tissue for cranial BNCT (Boron Neutron Capture Therapy) irradiations was recently completed at Harvard Medical School and MIT. Twenty-two subjects diagnosed with either glioblastoma multiforme or intracranial melanoma were treated between 1996 and 1999. Subjects received either one or two administrations of boronophenylalanine intravenously at doses between 250 and 350 mg/kg body weight, then exposed in one, two or three fields to epithermal neutrons at the MIT Research Reactor in one or two fractions. Over the course of the study, the maximum normal tissue dose target was increased from 8.8 to 14.2 RBE (Relative Biological Effectiveness) Gy in 10% increments. Subjects have been followed clinically and radiographically. Of those patients surviving beyond six months, no MRI (Magnetic Resonance Image) white-matter changes were observed and no long-term complications attributable to BNCT were evident. Tumor responses were observed, particularly with the melanoma subjects. With increasing doses, difficulties arose from long irradiation times (approximately 3 hours) and the emergence of acute reactions in the skin and mucosa. The trial was stopped in May 1999. Future trials will be initiated with the new high intensity, low background fission converter beam at MIT. (author)

    The MIT Research Reactor (MITR) is a MW nuclear research reactor that is owned and operated by the Massachusetts Institute of Technology to further its educational and research goals at both the undergraduate and graduate level. The reactor first achieved criticality in 1958. It was largely rebuilt in 1973/1974 by MIT staff and students, and its current license expires in August 1999. The current facility, which is designated as the MITR-H, uses a compact core with finned, aluminum-clad, plate-type fuel that is cooled and moderated by light water and reflected by heavy water. The reactor core can hold twenty-seven fuel elements. However, the normal configuration is twenty-four elements. A maximum of four fuel elements can be replaced with in-core experimental facilities. A unique feature of the MITR-II's design is that fixed absorber plates can be inserted in the upper half of the core. These cause the flux to peak in the lower half which benefits experimenters and also facilitates a fuel strategy that involves inversion of fuel elements midway through their life cycle. The MITR-II currently operates continuously for four weeks followed by shutdown of a few days for maintenance. This paper provides an overview of current activities at the MITR including preparations for re-licensing. The status of an on-going Phase-I clinical trial of boron neutron capture therapy for both glioblastoma multiforme and metastatic melanoma is described as well as the design of a fission converter facility for BNCT. Environmental research using neutron activation analysis is summarized as well as in-pile research focussed on LWR water chemistry and structural materials. (author)

  19. Teaching ``The Physics of Energy'' at MIT

    Science.gov (United States)

    Jaffe, Robert

    2009-05-01

    New physics courses on energy are popping up at colleges and universities across the country. Many require little or no previous physics background, aiming to introduce a broad audience to this complex and critical problem, often augmenting the scientific message with economic and policy discussions. Others are advanced courses, focussing on highly specialized subjects like solar voltaics, nuclear physics, or thermal fluids, for example. About two years ago Washington Taylor and I undertook to develop a course on the ``Physics of Energy'' open to all MIT students who had taken MIT's common core of university level calculus, physics, and chemistry. By avoiding higher level prerequisites, we aimed to attract and make the subject relevant to students in the life sciences, economics, etc. --- as well as physical scientists and engineers --- who want to approach energy issues in a sophisticated and analytical fashion, exploiting their background in calculus, mechanics, and E & M, but without having to take advanced courses in thermodynamics, quantum mechanics, or nuclear physics beforehand. Our object was to interweave teaching the fundamental physics principles at the foundations of energy science with the applications of those principles to energy systems. We envisioned a course that would present the basics of statistical, quantum, and fluid mechanics at a fairly sophisticated level and apply those concepts to the study of energy sources, conversion, transport, losses, storage, conservation, and end use. In the end we developed almost all of the material for the course from scratch. The course debuted this past fall. I will describe what we learned and what general lessons our experience might have for others who contemplate teaching energy physics broadly to a technically sophisticated audience.

    The energy-saving effect of single-room control of heating systems was investigated. For this purpose, a single-room control system was installed in a university building of 1961, and energy savings were monitored for a 2-year period, with the following results: 1. The potential savings amounted to 28% in both test years. 2. Different operating strategies were used in order to assess the contribution of heating system components. 3. The amortization period is less than 8 years, i.e. much less than the expected life of the systems. 4. Appropriate technical facilities improve the operation and control of a heat supply system in large buildings. 5. Proposals for improving the functionality of single room control systems were developed. 6. Recommendations were given on how to best modernize the control systems of large buildings. 7. The results can be applied to similar buildings as well. [German] Das Forschungsprojekt hatte folgende Ziele: 1. Die Ermittlung des Energie-Einsparpotentials 2. die daraus resultierende Wirtschaftlichkeit 3. die Optimierung der Regelstrategien 4. Erstellung von Handlungsempfehlungen bei der Sanierung mittels Einzelraumregelung. Es wurde in einem Trakt eines aus dem Jahre 1961 stammenden Hochschulgebaeudes, dessen Gebaeudehuelle sich noch in einem unveraenderten Zustand befindet, ein Einzelraumregelsystem mit zugehoeriger Gebaeudeleittechnik (GLT) installiert. Im Rahmen des Forschungsprojekts wurde ueber zwei Heizperioden die damit erreichte Einsparung an Heizenergie untersucht. Im Rahmen des Projektes konnte nachgewiesen werden, dass besonders bei Gebaeuden mit diskontinuierlicher Nutzung die regelungstechnische Sanierung sowohl oekonomisch als auch oekologisch sinnvoll ist. Im Einzelnen konnten die folgenden Ergebnisse ermittelt werden: 1. Es konnte in beiden Heizperioden des Untersuchungszeitraums ein Einsparpotential von ca. 28% nachgewiesen werden. 2.

    Despite the importance of student health and school hygiene as an aspect of the infrastructure of community health, few feasibility studies have been conducted on school health programs in developing countries. This study examined possible barriers to and challenges of such programs from the executive perspective in East Azerbaijan Province in Iran. This qualitative study used the content analysis approach to recognize barriers to and challenges of health promoting school program from the executive perspective. Fourteen experts were selected in the areas of children and adolescents and school health, physical education and school headmasters. Data were collected using semi-structured interviews and analyzed using the content analysis method. Five themes were extracted as major barriers and challenges: 1. Intraand inter-sectorial collaboration; 2. Policy and rule formulation; 3. Infrastructure and capacity; 4. Human resources; 5. Community involvement. The localized version of the current health promoting school program had major faults. If this program is considered to be a healthcare system priority, it should be revised to set effective policies for implementation and to sustain school health programs based on the capacities and objectives of each country.

    Full Text Available The purpose of this study was to examine the achievement of students in math and science subjects as the impact of using English as a medium of instruction at an international standard school. A questionnaire was used as a research instrument to 190 students at one international standard school in Jambi Province, Indonesia. A focus group discussion (FGD approach was undertaken to validate and verify the data gathered through the questionnaire and clarify some issues raised in the questionnaire. Data were analyzed by using descriptive statistics and Pearson Product Moment Correlation. It was found that the students’ demographic profile, attitude toward English and grades in math and science subjects were significantly related with their academic achievement. However, students’ perception on methods and techniques was not significantly related with their academic achievement in English, math, and the science subjects. The result showed that the implementation of English as a medium of instruction was not done well in the international standard school. This is perhaps due to the difficulty of learning science and math in English. This study provided information for policy makers, school leaders, researchers, and teacher educators to understand how the policy is implemented at the school level. The challenges of attempting too ambitious linguistic and academic goals in the school were discussed as were policy implications and future research.

    Physical and emotional violence against adolescents is a neglected, but growing problem globally. Violence against adolescents negatively affects the victim in terms of physical health, school attendance and performance and social adjustment. The literature on the prevalence and associated factors of bullying against adolescents is sparse in southern Africa outside South Africa. Such data are even sparser for Malawi. The current study was conducted to estimate the prevalence of self-reported bullying and its personal and social correlates. A secondary analysis of the Malawi School-Based Student Health Survey (2009) was done. Descriptive analyses were done to describe the sample and estimate the prevalence of reporting history of bullying in the past 30 days preceding the survey. Logistic regression analysis was done to assess the association between several factors and being a victim of bullying. Crude and adjusted odds ratios are reported. A total of 2,264 in-school adolescents participated in the Malawi School-Based Student Health Survey of 2009. Just under half (44.5%) reported having been bullied in the previous month to the survey (44.1% among boys versus 44.9% among girls). Compared to adolescents of age 16 years or older, those who were 12 years old or younger and those who were 14 years of age were more likely to be bullied (AOR=1.54; 95% CI [1.41, 1.76]) and OR=1.26; 95% CI [1.21, 1.31]) respectively. The other risk factors that were identified in the analysis were loneliness (AOR = 2.23; 95% CI [2.20, 2.27]), and being worried (AOR = 2.80; 95% CI [2.76, 2.85[). Adolescents who had no close friends were 14% (AOR = 1.14; 95% CI [1.11-1.17]) more likely to be reporting bullied compared to adolescents who reported having close friends. Adolescents who smoked cigarettes were more than three times more likely to reporting be bullied compared to non-smokers (AOR=3.97; 955 CI [3.83, 4.10]), while those who drank alcohol were more than twice as likely to be

    IM, E. S.; Eltahir, E. A. B.

    2014-12-01

    Given that warming of the climate system is unequivocal (IPCC AR5), accurate assessment of future climate is essential to understand the impact of climate change due to global warming. Modelling the climate change of the Maritime Continent is particularly challenge, showing a high degree of uncertainty. Compared to other regions, model agreement of future projections in response to anthropogenic emission forcings is much less. Furthermore, the spatial and temporal behaviors of climate projections seem to vary significantly due to a complex geographical condition and a wide range of scale interactions. For the fine-scale climate information (27 km) suitable for representing the complexity of climate change over the Maritime Continent, dynamical downscaling is performed using the MIT regional climate model (MRCM) during two thirty-year period for reference (1970-1999) and future (2070-2099) climate. Initial and boundary conditions are provided by Community Earth System Model (CESM) simulations under the emission scenarios projected by MIT Integrated Global System Model (IGSM). Changes in mean climate as well as the frequency and intensity of extreme climate events are investigated at various temporal and spatial scales. Our analysis is primarily centered on the different behavior of changes in convective and large-scale precipitation over land vs. ocean during dry vs. wet season. In addition, we attempt to find the added value to downscaled results over the Maritime Continent through the comparison between MRCM and CESM projection.

    Bullying has public health importance. It has been reported that both the victims and perpetrators of bullying are more likely to have suicidal ideation and other suicidal behaviours. Moreover, bullying can be a precursor for school violence and can contribute to poor academic performance. The purpose of the study was to raise awareness on the subject in China. We, therefore conducted an analysis of secondary data to determine the prevalence and correlates of having been bullied among in-school adolescents. The data was taken from the Beijing Global School-Based Health Survey conducted in 2003. A weighted analysis to reduce bias due to differing patterns of non-response was conducted using statistical software (SPSS version 14.0). We conducted a backward logistic regression analysis to determine independent predictors for being bullied. Out of a total of 2,348 in-school adolescents who participated in the survey, 20% (23% males, and 17% females) reported having been bullied. Risk factors for having been bullied were loneliness (adjusted odds ratio (AOR) = 1.44; 95% confidence interval (CI) 1.42-1.45), being worried (AOR = 1.30; 95% CI 1.29-1.32), being sad or having feelings of hopelessness (AOR = 1.21; 95% CI 1.19-1.22), smoking cigarettes (AOR = 1.09; 95% CI 1.08-1.11), drinking alcohol (AOR = 1.31; 95% CI 1.29-1.32), and being truant (AOR = 1.24; 95% CI 1.22-1.27). Meanwhile protective factors were having close friends (AOR = 0.84; 95% CI 0.83-0.86), receiving parental supervision (AOR = 0.80; 95% CI 0.80-0.81), and ever been drunk (AOR = 0.86; 95% CI 0.84-0.87). We believe the results of this study will raise awareness among school health practitioners and administrators, paediatric psychiatrists and psychologists on the prevalence and correlates of bullying among adolescents in Beijing, China.

    2017-01-01

    Hintergrund: Canine Mammatumoren (CMT) sind wegen ihrer Häufigkeit und hohen Malignitätsrate eine Herausforderung für die Veterinärmedizin. Bisher ist noch keine postoperative adjuvante Therapie als wirksamer Standard etabliert und in den nächsten Jahren wohl auch nicht zu erwarten. Zusätzlich ist die Frage nach der Verträglichkeit einer adjuvanten Therapie mit Erhaltung oder Verbesserung der Lebensqualität (LQ) wichtig. Die Therapie mit Mistelextrakten (Viscum album L.; VAE) ist in der Humanonkologie nach adjuvanter Tumorbasistherapie (Chemotherapie und Bestrahlung) eine sehr häufig verwendete, zusätzliche adjuvante Behandlungsmethode. Auch bei verschiedenen Tierarten werden inzwischen Mistelpräparate in der Onkologie erfolgreich angewendet. Methoden: Überprüfung von Wirkung und Nutzen einer postoperativen, adjuvanten Misteltherapie beim CMT sowie Erfassung der LQ unter der VAE-Behandlung. Ausgewertet wurden 56 Hündinnen mit Mammaadenokarzinom, 33 ausschließlich operierte Kontrolltiere und 23 operierte Tiere, die adjuvant VAE erhielten. Ergebnisse: Die mediane Überlebenszeit (MST) aller Tiere (n = 56) betrug 32 Monate (Interquartilbereich 13-51 Monate). Im deskriptiven Vergleich der Überlebenszeiten (ST) nach Kaplan-Meier waren nach 12, 24, 36 bzw. 48 Monaten noch 24, 20, 15 bzw. 5 Hündinnen (entsprechend 72,7%, 60,6%, 45,1%, 12,4%) der Kontrollgruppe sowie 19, 14, 11 und 1 Hündin (82,6%, 60,9%, 47,8%, 4,3%) der VAE-Gruppe am Leben. Die VAE-Therapie führte zu einem geringeren Gesamtversterberisiko, das statistisch nicht signifikant war (Hazard Ratio (HR) 0,530, 95%-Konfidenzintervall (KI) 0,222-1,262; p = 0,15). Tendenziell (p = 0,07) zeigte sich eine Verringerung des tumorbedingten Sterberisikos auf 25% (HR 0,251, 95%-KI 0,056-1,122). Schlussfolgerungen: Es kann eine Tendenz zur Senkung des tumorbedingten Sterberisikos der VAE-Gruppe bei guter Verträglichkeit der Therapie angenommen werden. Die LQ der Tiere blieb über die gesamte

    2016-02-01

    A two week high school course for high-achieving 10th-12th graders was developed through the combined efforts of Scripps Institution of Oceanography (SIO) Graduate Students and UC San Diego Academic Connections. For the high school students involved, one week was spent at SIO learning basic climate science and researching climate-related topics, and one week was spent in Washington D.C. lobbying Congress for an environmental issue of their choosing. The specific learning goals of the course were for students to (1) collect, analyze and interpret scientific data, (2) synthesize scientific research for policy recommendations, (3) craft and deliver a compelling policy message, and (4) understand and experience change. In this first year, 10 students conducted research on two scientific topics; sea level rise using pier temperature data and California rainfall statistics using weather stations. Simultaneous lessons on policy messaging helped students learn how to focus scientific information for non-scientists. In combining the importance of statistics from their Science lessons with effective communication from their Policy lessons, the students developed issue papers which highlighted an environmental problem, the solution, and the reason their solution is most effective. The course culminated in two days of meetings on Capitol Hill, where they presented their solutions to their Congressional and Senate Members, conversed with policymakers, and received constructive feedback. Throughout the process, the students effectively defined arguments for an environmental topic in a program developed by SIO Graduate Students.

    Good evening and thank you - Director Spradling, members of the faculty, alumni, family and friends of this graduating class, and especially the graduates of the American International School Vienna Class of 2003. Let me begin by thanking you for the invitation to share this important occasion with you. In my work, I frequently speak with diplomats and statesmen about how we can make our world a better place for 'future generations' - but I don't often get an opportunity like this one: to speak directly to you - the generation that holds the future in its hands. And I feel particularly fortunate to be speaking to such an international graduating class. As an Egyptian educated in the US, working in Vienna, with my children living in London, and an entire career devoted to international co-operation, I can tell you that I consider myself primarily a global citizen. And for me, thinking globally is now almost a must. This is because the world we live in has become highly interdependent. Many aspects of our modern life - Internet communication, the global marketplace, global warming, even the fights against disease and terrorism - point to the fact that the human race has entered a new era - a global era - and there is no turning back. To members of your generation, this might not seem like news. To your parents, the Internet feels like a new way of life (in fact - speaking for your parents, or perhaps your grandparents, we can still remember when television was a new and awesome thing) - but to you, global interaction and communication is a natural part of life. In fact, you especially are well equipped for this interdependent world - because the development of a global perspective is an essential feature of your educational environment here at the American International School. So you are 'ahead of the curve' in this regard. Yes, you are Brazilian, you are Indian, you are Iranian, you are Austrian, you are Japanese - you are one of the fifty nationalities that make

    Mandin, C; Derbez, M; Kirchner, S

    2012-07-01

    This review provides a global overview of indoor air quality issues in schools, office buildings and recreational settings. It presents the most recent scientific publications and the on-going work conducted in France in the frame of the indoor air quality Observatory. Monitoring campaigns on indoor air quality in schools have been carried out in the recent years in Europe. However, few studies have specifically addressed the role of exposure in these buildings on children's health. Indoor air quality in office buildings has been little studied so far. However, some specificities, such as emissions from electronic devices, frequent cleaning, impossibility to open windows in high-rise buildings, for example, should be examined and their role on the health and comfort studied. Finally, even if the time spent in recreational settings is short, the quality of indoor air should also be considered because of specific pollution. This is the case of indoor swimming pools (exposure to chlorination byproducts) and ice-rinks (exposure to exhaust from machines used to smooth the ice). Copyright © 2012 Elsevier Masson SAS.

    2007-11-01

    Full Text Available Abstract Background Educational attainment is an important determinant of diverse health outcomes. Truancy among adolescents jeopardizes chances of achieving their educational goals. Truant behaviors are also associated with various psychosocial problems. There is however limited data on the prevalence and factors associated with truancy among adolescents in Africa. Methods We used data from the Swaziland Global School-Based Health Survey (GSHS conducted in 2003 to estimate the prevalence of self-reported truancy within the last 30 days among adolescents. We also assessed the association between self-reported truancy and a selected list of independent variables using logistic regression analysis. Results A total of 7341 students participated in the study. In analysis of available data, 2526 (36.2% and 4470 (63.8% were males and females respectively. The overall prevalence of truancy within the last 30 days preceding the study was 21.6%. Prevalence of truancy was 27.4% (605 and 17.9% (723 in males and females respectively. In multivariate logistic regression analysis, being a male, having been bullied, lower school grades, and alcohol use were positively associated with truancy. Adolescents who perceived themselves as having parental support were less likely to have reported being truant. Conclusion Truancy among adolescents in Swaziland should be regarded as an important social problem as it is relatively prevalent. The design and implementation of intervention programs aimed to reduce truant behaviours should incorporate our knowledge of the factors identified as associated with bullying.

    2018-01-01

    Radiology interconnects medical disciplines given that a working understanding of imaging is essential to clinicians of every specialty. Using online education, we created a globally accessible, web-based undergraduate medical radiology curriculum modeled after the National Medical Student Curriculum in Radiology program of the Alliance of Medical Student Educators in Radiology. Seventy-four radiology faculty-mentored video modules were produced, 50 of which were integrated into the 1st-year anatomy course. We administered tests to medical students before and after students saw the videos to assess the effectiveness of the modules. We surveyed students on their interests in pursuing radiology as a career before and after participating in this curriculum. On the preexamination questions, the mean score was 58.0%, which increased to 83.6% on the pair-matched imaging-related questions on the actual examination. Before participating in the new curriculum, 88% of students did not express an interest in radiology, and 9% were undecided about radiology as a future career. There was an increase in students who reported that they would definitely or most likely pursue a career in radiology (7%) after they had viewed the lectures. Radiology education is now available to a greater number of multidisciplinary learners worldwide. This project produced a comprehensive, globally accessible radiology curriculum in a self-paced, flexible learning format for new generations of physicians.

    The micro turbine study began a few years ago at the MIT, with the participation of specialists from different fields. The purpose is the development of a MEMS (micro electro mechanical systems) based, 1 cm in diameter, micro gas turbine. Potential applications are devoted to micro drone propulsion, electric power generation for portable power sources in order to replace heavy Lithium batteries, satellite motorization, the surface distributed power for boundary suction on plane wings. The manufacturing constraints at such small scales lead to 2-D extruded shapes. The physical constraints stem from viscous effects and from limitations given by 2-D geometry. The time scales are generally shorter than for conventional machines. Otherwise the material properties are better at such length scales. Transposition from conventional turbomachinery laws is no more applicable and new design methods must be established. The present paper highlights the project progress and the technology breakthroughs. (author)

    Die Detektion von Hindernissen vor dem Automobil ist eine Hauptanforderung an moderne Fahrerassistenzsysteme (FAS). In dieser Arbeit wird ein System vorgestellt, das mit Hilfe einer PMDKamera (Photomischdetektor) Hindernisse auf der Fahrspur erkennt und deren relevante Parameter bestimmt. Durch die PMD-Kamera werden zunächst 3D-Tiefenbilder der Fahrzeugumwelt generiert. Nach einem initialen Filterprozess werden im Tiefenbild mit Hilfe eines Bereichswachstumsverfahrens Hindernisse gesucht. Zur Stabilisierung des Verfahrens und zur Parameterberechnung wird ein Kaiman Filter eingesetzt. Das Ergebnis ist eine Liste aller Hindernisse im Fahrbereich des Automobils.

  9. NASA/JPL CLIMATE DAY: Middle and High School Students Get the Facts about Global Climate Change

    Science.gov (United States)

    Richardson, Annie; Callery, Susan; Srinivasan, Margaret

    2013-04-01

    In 2007, NASA Headquarters requested that Earth Science outreach teams brainstorm new education and public outreach activities that would focus on the topic of global climate change. At the Jet Propulsion Laboratory (JPL), Annie Richardson, outreach lead for the Ocean Surface Topography missions came up with the idea of a "Climate Day", capitalizing on the popular Earth Day name and events held annually throughout the world. JPL Climate Day would be an education and public outreach event whose objectives are to provide the latest scientific facts about global climate change - including the role the ocean plays in it, the contributions that NASA/JPL satellites and scientists make to the body of knowledge on the topic, and what we as individuals can do to promote global sustainability. The primary goal is that participants get this information in a fun and exciting environment, and walk away feeling empowered and capable of confidently engaging in the global climate debate. In March 2008, JPL and its partners held the first Climate Day event. 950 students from seven school districts heard from five scientists; visited exhibits, and participated in hands-on-activities. Pleased with the outcome, we organized JPL Climate Day 2010 at the Pasadena Convention Center in Pasadena, California, reaching more than 1700 students, teachers, and members of the general public over two days. Taking note of this successful model, NASA funded a multi-center, NASA Climate Day proposal in 2010 to expand Climate Day nation-wide. The NASA Climate Day proposal is a three-pronged project consisting of a cadre of Earth Ambassadors selected from among NASA-affiliated informal educators; a "Climate Day Kit" consisting of climate-related electronic resources available to the Earth Ambassadors; and NASA Climate Day events to be held in Earth Ambassador communities across the United States. NASA/JPL continues to host the original Climate Day event and in 2012 held its 4th event, at the Pasadena

    The abundance and significant contribution to global primary production of the marine cyanobacterium Prochlorococcus have made it one of the main models in marine ecology. Several conditions known to cause strong effects on the regulation of N-related enzymes in other cyanobacteria lacked such effect in Prochlorococcus. Prochlorococcus sp. strain MIT9313 is one of the most early-branching strains among the members of this genus. In order to further understand the C/N control system in this cyanobacterium, we studied the effect of the absence of three key elements in the ocean, namely N, P and Fe, as well as the effect of inhibitors of the N assimilation or photosynthesis on the N metabolism of this strain. Furthermore, we focused our work in the effect of ageing, as the age of cultures has clear effects on the regulation of some enzymes in Prochlorococcus. To reach this goal, expression of the main three regulators involved in N assimilation in cyanobacteria, namely ntcA, glnB and pipX, as well as that of icd (encoding for isocitrate dehydrogenase) were analysed. Our results show that the control of the main proteins involved in the C/N balance in strain MIT9313 differs from other model Prochlorococcus strains. © FEMS 2017. All rights reserved.

    The safety limits of transport by monorails were determined within the framework of a test project. The safety-related components of the system, in particular the rail system with its suspensions and the drive and braking system, were investigated for normal and heavy load transport. In addition to operational measurements for actual stressing of the components tests were conducted on test benches to determine the dynamic strength. The concept of a new forward-looking monorail system with greater safety was subsequently developed with the aid of the results obtained. The compatibility with the previous components was ensured. Compared to the determined load capacity limits a development requirement for monorail suspension anchor bolts, diesel- and battery-operated trolleys as well as braking trolleys for ropeways were derived. The other components are already adequately dimensioned. (orig.) [German] Im Rahmen eines Untersuchungsvorhabens wurden die sicherheitlichen Grenzen des Transports mit EHB ermittelt. Die sicherheitsrelevanten Bauteile des Systems, insbesondere das Schienensystem mit seinen Aufhaengungen sowie das Antriebs- und Bremssystem, wurden fuer den Normal- und den Schwerlasttransport untersucht. Neben Betriebsmessungen zur tatsaechlichen Beanspruchung der Bauteile erfolgten Pruefstandsuntersuchungen zur dynamischen Festigkeit. Mit Hilfe der gewonnenen Ergebnisse wurde anschliessend das Konzept fuer ein neues, zukunftsorientiertes EHB-System mit erhoehter Sicherheit erarbeitet. Die Kompatibilitaet zu den bisherigen Bauteilen wurde dabei gewaehrleistet. Im Vergleich zu den ermittelten Belastbarkeitsgrenzen wurde daraus ein Entwicklungsbedarf bei EHB-Aufhaengeankern, Diesel- und Batteriekatzen sowie Bremskatzen fuer Seilbahnen abgeleitet. Die uebrigen Bauteile sind bereits jetzt ausreichend bemessen. (orig.)

    Today continuous subcutaneous insulin infusion (CSII) is frequently used in children and adolescents with type 1 diabetes mellitus. The present cross-sectional trial aimed to document current practice, quality of diabetes control and incidence of acute complications in different age-groups under CSII vs. multiple daily insulin injection therapy (MIT). Moreover the survey analyzed socio-demographic backgrounds of the patients. A total of 901 patients (age 11.5±4.0, diabetes duration 4.0±3.6 years) was entered in the database. Clinical data, laboratory parameters and, using a standardized questionnaire, socio-demographic data were assessed. For age-related analyses patients were allocated to 4 groups: pre-school children (MIT. Patients with CSII vs. MIT had a longer diabetes duration, they used more frequently insulin analogues, performed more frequently blood-glucose self-tests and had a lower insulin dosage per kilogram body weight. In respect of HbA1c, the mean amplitude of blood-glucose excursions, but also of lipids, creatinine, microalbuminuria and blood pressure, there were no differences in neither age-group between patients with CSII and MIT. In patients with CSII and MIT, there was a tendency (pMIT there is an increase of HbA1c towards adolescence. It must also highlighted that CSII seems to be expansive and that CSII is more frequently used in patients with better educational levels and deriving from higher social classes. © Georg Thieme Verlag KG Stuttgart · New York.

  4. Understanding Global Change (UGC) as a Unifying Conceptual Framework for Teaching Ecology: Using UGC in a High School Biology Program to Integrate Earth Science and Biology, and to Demonstrate the Value of Modeling Global Systems in Promoting Conceptual Learning

    2017-12-01

    Global change science is ideal for NGSS-informed teaching, but presents a serious challenge to K-12 educators because it is complex and interdisciplinary- combining earth science, biology, chemistry, and physics. Global systems are themselves complex. Adding anthropogenic influences on those systems creates a formidable list of topics - greenhouse effect, climate change, nitrogen enrichment, introduced species, land-use change among them - which are often presented as a disconnected "laundry list" of "facts." This complexity, combined with public and mass-media scientific illiteracy, leaves global change science vulnerable to misrepresentation and politicization, creating additional challenges to teachers in public schools. Ample stand-alone, one-off, online resources, many of them excellent, are (to date) underutilized by teachers in the high school science course taken by most students: biology. The Understanding Global Change project (UGC) from the UC Berkeley Museum of Paleontology has created a conceptual framework that organizes, connects, and explains global systems, human and non-human drivers of change in those systems, and measurable changes in those systems. This organization and framework employ core ideas, crosscutting concepts, structure/function relationships, and system models in a unique format that facilitates authentic understanding, rather than memorization. This system serves as an organizing framework for the entire ecology unit of a forthcoming mainstream high school biology program. The UGC system model is introduced up front with its core informational graphic. The model is elaborated, step by step, by adding concepts and processes as they are introduced and explained in each chapter. The informational graphic is thus used in several ways: to organize material as it is presented, to summarize topics in each chapter and put them in perspective, and for review and critical thinking exercises that supplement the usual end-of-chapter lists of

Analyses are based on the Global School-Based Student Health Survey (GSHS conducted in Zambia (2004 of students primarily 11 to 16 years of age (=2257. Four statistical models were computed to test the associations between alcohol marketing and education and alcohol use, while controlling for possible confounding factors. Alcohol marketing, specifically through providing free alcohol through a company representative, was associated with drunkenness (AOR = 1.49; 95% CI: 1.09–2.02 and problem drinking (AOR = 1.41; 95% CI: 1.06–1.87 among youth after controlling for demographic characteristics, risky behaviors, and alcohol education. However, alcohol education was not associated with drunkenness or problem drinking. These findings underscore the importance of restricting alcohol marketing practices as an important policy strategy for reducing alcohol use and its dire consequences among vulnerable youth.

Methods: In an area of moderate iodine deficiency 163 goitrous patients without and 179 with functional autonomy all clinically euthyroid were compared by sex, age, signs and symptoms, sonographic results, qualitative and quantitative scintigraphy without and with suppression, TRH test, hormone concentrations and iodine excretion in the urine. Results: Age, signs and symptoms, thyroid volume and structure did not contribute sufficiently to diagnosis. To detect functional autonomy quantitative scintigraphy under suppression was superior to the TRH test. Increased hormone concentrations were observed in 15% of patients with functional autonomy. A global {sup 99m}Tc thyroid uptake of {>=}3% under suppression indicates a higher risk of spontaneous hyperthyroidism. It was present in 20% of patients with functional autonomy. Conclusion: to diagnose and treat adequately functional autonomy in euthyroid goitre quantitative scintigraphy, determination of TSH and hormone concentrations are inevitable. (orig.)

    This project looks to help teachers utilize iPad technology in their classrooms as an instructional tool for Earth system science and connections to the Big Ideas in Earth Science. The project is part of Penn State University's National Science Foundation (NSF) Targeted Math Science Partnership grant, with one goal of the grant to help current middle school teachers across Pennsylvania engage students with significant and complex questions of Earth science. The free Apple software iBooks Author was used to create an electronic book for the iPad, focusing on a variety of controversial issues impacting the hydrosphere. The iBook includes image slideshows, embedded videos, interactive images and quizzes, and critical thinking questions along Bloom's Taxonomic Scale of Learning Objectives. Outlined in the introductory iBook chapters are the Big Ideas of Earth System Science and an overview of Earth's spheres. Since the book targets the hydrosphere, each subsequent chapter focuses on specific water issues, including glacial melts, aquifer depletion, coastal oil pollution, marine debris, and fresh-water chemical contamination. Each chapter is presented in a case study format that highlights the history of the issue, the development and current status of the issue, and some solutions that have been generated. The next section includes critical thinking questions in an open-ended discussion format that focus on the Big Ideas, proposing solutions for rectifying the situation, and/or assignments specifically targeting an idea presented in the case study chapter. Short, comprehensive multiple-choice quizzes are also in each chapter. Throughout the iBook, students are free to watch videos, explore the content and form their own opinions. As a result, this iBook fulfills the grant objective by engaging teachers and students with an innovative technological presentation that incorporates Earth system science with current case studies regarding global water issues.

    The MIT-Skywalker is a robotic device developed for the rehabilitation of gait and balance after a neurological injury. This device has been designed based on the concept of a passive walker and provides three distinct training modes: discrete movement, rhythmic movement, and balance training. In this paper, we present our efforts to evaluate the comfort of a bicycle/saddle seat design for the system's novel actuated body weight support device. We employed different bicycle and saddle seats and evaluated comfort using objective and subjective measures. Here we will summarize the results obtained from a study of fifteen healthy subjects and one stroke patient that led to the selection of a saddle seat design for the MIT-Skywalker.

    Full Text Available Es gibt Menschen, die die innere Gewissheit besitzen, dass ihre Geschlechtsidentität nicht zu ihrem biologischen Ursprungsgeschlecht passt. Durch die Entwicklungen in der Medizin in den letzten hundert Jahren ist es möglich geworden, die körperlichen Geschlechtsmerkmale an das innerlich erlebte Geschlecht anzupassen. Die Zahl der Hilfesuchenden in den ärztlichen Ambulanzen und Privatpraxen hat in den vergangenen Jahren deutlich zugenommen. Das Vorgehen bei der Diagnostik und Therapieeinleitung erlebt zurzeit eine deutliche Veränderung hin zu mehr Patientenzentriertheit und Individualisierung des Transitionsprozesses. Dabei bildet die geschlechtsangleichende Hormontherapie ein wesentliches Standbein in der körperlichen Angleichung an das Gegengeschlecht. Unter Beachtung von bestimmten Sicherheitsaspekten ist eine Hormontherapie mit Sexualhormonen sicher und einfach durchzuführen. Regelmäßige Verlaufskontrollen sowie der offene und affirmative Umgang mit den Betroffenen tragen zudem wesentlich zur Sicherheit in der Behandlung bei.

  16. Are the N and Δ deformed MIT bags

    Clement, G.; Maamache, M.

    1985-01-01

    The influence of the one-gluon exchange interaction, zero-point energy, and centre-of-mass correction, on the deformation of the nucleon and Δ bags, is studied in the MIT bag model. If the sharp MIT boundary conditions are taken seriously, the strong dependence of the zero-point energy on the deformation leads to the collapse of the N and Δ bags for realistic values of the strong fine structure constant α/sub S/. If on the other hand the zero-point energy is ignored altogether, then the nucleon, spherical for α/sub S/ 3.25, while the Δ is always prolate. The various predictions of the model are, for α/sub S/> or approx. =3.25, consistent with experiment, except for the proton magnetic moment which is only about 40% of the experimental value

  17. Properties of hybrid stars in an extended MIT bag model

    Bao Tmurbagan; Liu Guangzhou; Zhu Mingfeng

    2009-01-01

    The properties of hybrid stars are investigated in the framework of the relativistic mean field theory (RMFT) and an MIT bag model with density-dependent bag constant to describe the hadron phase (HP) and quark phase (QP), respectively. We find that the density-dependent B(ρ) decreases with baryon density ρ; this decrement makes the strange quark matter become more energetically favorable than ever; which makes the threshold densities of the hadron-quark phase transition lower than those of the original bag constant case. In this case, the hyperon degrees of freedom can not be considered. As a result, the equations of state of a star in the mixed phase (MP) become softer whereas those in the QP become stiffer, and the radii of the star obviously decrease. This indicates that the extended MIT bag model is more suitable to describe hybrid stars with small radii. (authors)

    In this work we revisit the MIT bag model to describe quark matter within both the usual Fermi-Dirac and the Tsallis statistics. We verify the effects of the non-additivity of the latter by analysing two different pictures: the first order phase transition of the QCD phase diagram and stellar matter properties. While the QCD phase diagram is visually affected by the Tsallis statistics, the resulting effects on quark star macroscopic properties are barely noticed. (orig.)

    Obwohl subklinische Enthesiopathie ein gut etabliertes diagnostisches Merkmal der Psoriasisarthritis (PsA) ist, wird sie häufig übersehen, da viele Patienten asymptomatisch sind. Gäbe es klinische Hinweise auf das Vorliegen einer Enthesiopathie, würde dies den Klinikern die Möglichkeit eröffnen, eine PsA frühzeitig zu diagnostizieren. Es wurde eine monozentrische prospektive Studie mit insgesamt 90 Psoriasis-Patienten durchgeführt, um mittels Ultraschall das Vorliegen von Enthesenanomalien zu untersuchen und eine Korrelation mit dem Befall der Nägel festzustellen. Enthesenanomalien wurden bei 23 Patienten (25,5 %) gefunden, von denen 19 (82,6 %) Nagelbefall aufwiesen. Bei 4 Patienten waren die Nägel nicht betroffen. Enthesiopathie lag bei 31,1 % (19/61) der Patienten mit Onychopathie vor, von den Patienten ohne Nagelbefall litten nur 13,8 % (4/29) an Enthesiopathie (p = 0,07). Zwischen dem Target-NAPSI-Score und dem Vorliegen einer Enthesiopathie bestand eine signifikante Korrelation. Eine signifikante Korrelation bestand darüber hinaus auch zwischen dem Vorliegen einer Enthesiopathie und der Anzahl der betroffenen Nägel (p = 0,035). Klinische Belege für eine Onychopathie können der Schlüssel für die frühe Diagnose einer Enthesiopathie bei Psoriasis-Patienten sein. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

    In the last decade, the rehabilitation of postlingually deaf adults and prelingually deaf children with cochlear implants has been established as a treatment of deafness. The technological development of the implant devices and improvement of the surgical technique have led to a considerable increase of hearing performance during the last years. The postlingually deaf adults are able to use the telephone and may be integrated in their original job. Prelingually deaf children can even visit normal schools after cochlear implantation and hearing rehabilitation training. In order to preoperatively establish the state of the cochlear, radiological diagnosis of the temporal bone is necessary. High resolution computerized tomography imaging of the temporal bone with coronar and axial 1 mm slices and MRI with thin slice technique (three dimensional, T2 weighted turbo-spinecho sequence with 0.7 mm slices) have proved to be valuable according to our experience. Furthermore a postoperative synoptical X-ray, in a modified Chausse III projection, offers good information about the position of the implant and insertion of the stimulating electrode into the cochlea.

    2010-01-01

    Non-communicable diseases (NCD), such as heart disease, stroke, cancer and diabetes, are by far the leading cause of mortality in the world, representing 60% of all deaths. Unhealthy diets and physical inactivity are well-established risk factors for overweight and the major NCD. In response to the rapid global growth of the NCD burden, the 2008 Action Plan on Prevention and Control of NCD and the 2004 Global Strategy on Diet, Physical Activity and Health (DPAS) have been developed and endorsed as key international policy instruments. As part of the work of the World Health Organization (WHO) to implement these resolutions, a framework describing the core elements for the development and implementation of a national school policy focused on diet and physical activity has been developed. This framework is included in the "DPAS implementation tool box", and it aims to guide policy-makers in the development and implementation of policies that promote healthy eating and physical activity in the school setting through changes in environment, behaviour and education. The article describes the key elements of the framework and details how this tool is integrated into other WHO activities to provide leadership, guidance, capacity building, evidence-based recommendations and advocacy for action to improve dietary practices and increase physical activity globally.

    Die Behandlung von Psoriasis-Patienten mit einer Kombination aus Fumarsäureestern (FSE, Fumaderm ® ) und Phototherapie (UV) ist verbreitet, wurde aber im Rahmen von Studien wenig untersucht. Bisher liegen lediglich Daten aus einer kleinen Pilotstudie vor. Intention dieser Studie war, eine FSE/UV-Kombinationsbehandlung an einem größeren Patientenkollektiv mit mittelschwerer bis schwerer Psoriasis zu untersuchen. In dieser prospektiven, multizentrischen, nichtinterventionellen Studie wurden Daten von Patienten mit FSE/UV-Kombinationstherapie hinsichtlich der Wirksamkeit (PGA' PASI, DLQI, EQ-5D), Sicherheit und Dosierung über einen Zeitraum von zwölf Monaten erfasst und mit Daten einer retrospektiven Studie mit FSE-Monotherapie verglichen. Es wurden Daten von 363 Patienten ausgewertet. Unter der Kombinationstherapie verbesserten sich alle Wirksamkeitsparameter deutlich. Im Vergleich zur Monotherapie mit FSE konnte durch die Kombination mit UV ein schnellerer Wirkeintritt erzielt werden, wobei nach zwölf Monaten kein Unterschied in der Wirksamkeit bestand. Die Dauer und Art der Phototherapie zeigte keinen Einfluss auf die Wirksamkeitsparameter. Allgemein wurde die Kombinationstherapie gut vertragen. Unerwünschte Ereignisse wurden bei 7 % der Patienten berichtet. Die FSE/UV Kombinationstherapie zeigt eine gute Wirksamkeit und Verträglichkeit und kann zu einem schnelleren Wirkeintritt führen. Eine Kombinationstherapie erscheint vor allem in den ersten drei Monaten der FSE Behandlung sinnvoll. © 2017 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

    Eine Säule der kausalen Therapie bei Patienten mit Ulcus cruris venosum ist die Kompressionstherapie. Sie unterstützt die Abheilung, reduziert Schmerzen und Rezidive und steigert die Lebensqualität. Bislang existieren kaum wissenschaftliche Daten zu dem Versorgungsstand und fachspezifischem Wissen von Patienten mit Ulcus cruris venosum. Standardisierte Fragebögen wurden bundesweit in 55 Pflegediensten, 32 Arztpraxen, vier Wundzentren und -sprechstunden sowie einem Pflegetherapiestützpunkt von Patienten mit Ulcus cruris venosum bei Erstvorstellung anonym ausgefüllt. Insgesamt nahmen 177 Patienten (Durchschnittsalter 69,4 Jahre; 75,1 % Frauen) teil. Ein florides Ulcus cruris venosum bestand im Mittel 17 Monate. 31,1 % hatten keine Kompressionstherapie, 40,1 % Binden und 28,8 % Strümpfe. Bei der Bestrumpfung hatten 13,7 % Kompressionsklasse III, 64,7 % Kompressionsklasse II und 19,6 % Kompressionsklasse I. 70,6 % legten die Strümpfe nach dem Aufstehen an, 21,1 % trugen sie Tag und Nacht. 39,2 % bereiteten die Strümpfe Beschwerden. Lediglich 11,7 % hatten eine An- und Ausziehhilfe. Die Binden wurden im Mittel 40,7 Wochen getragen und bei 69 % nicht unterpolstert. Bei 2,8 % wurde der Knöchel- und Waden-Umfang zur Erfolgskontrolle gemessen. Venensport machten 45,9 %. Ein Drittel hatte keine Kompressionsversorgung, obwohl diese eine Basismaßnahme der Therapie des Ulcus cruris venosum ist. Zudem ist deren korrekte Auswahl und Anwendung angesichts der langen Bestandsdauer der Ulzerationen zu hinterfragen.

  1. Comments on the MIT Assessment of the Mars One Plan

    Science.gov (United States)

    Jones, Harry W.

    2015-01-01

    The MIT assessment of the Mars One mission plan reveals design assumptions that would cause significant difficulties. Growing crops in the crew chamber produces excessive oxygen levels. The assumed in-situ resource utilization (ISRU) equipment has too low a Technology Readiness Level (TRL). The required spare parts cause a large and increasing launch mass logistics burden. The assumed International Space Station (ISS) Environmental Control and Life Support (ECLS) technologies were developed for microgravity and therefore are not suitable for Mars gravity. Growing food requires more mass than sending food from Earth. The large number of spares is due to the relatively low reliability of ECLS and the low TRL of ISRU. The Mars One habitat design is similar to past concepts but does not incorporate current knowledge. The MIT architecture analysis tool for long-term settlements on the Martian surface includes an ECLS system simulation, an ISRU sizing model, and an analysis of required spares. The MIT tool showed the need for separate crop and crew chambers, the large spare parts logistics, that crops require more mass than Earth food, and that more spares are needed if reliability is lower. That ISRU has low TRL and ISS ECLS was designed for microgravity are well known. Interestingly, the results produced by the architecture analysis tool - separate crop chamber, large spares mass, large crop chamber mass, and low reliability requiring more spares - were also well known. A common approach to ECLS architecture analysis is to build a complex model that is intended to be all-inclusive and is hoped will help solve all design problems. Such models can struggle to replicate obvious and well-known results and are often unable to answer unanticipated new questions. A better approach would be to survey the literature for background knowledge and then directly analyze the important problems.

    1999-10-01

    Having grown at a rate of 15% since the middle of the 1980s the photovoltaic market today commands an annual module production of more than 100 MW{sub p}. In Germany altogether 10,000 PV systems with a total power output of 10 MW{sub p} were newly installed in 1997 alone. In 1990 the market was boosted by the heavily subsidised 1000 roofs programme, under which in the end more than 2,000 systems were installed on the roofs of mostly one-family houses. With power ratings ranging from 1 to 5 kW these decentral plants require roof surface areas between 10 and 50 m-2. On average they generate 800 kWh of electricity per kW of installed power. According to a number of studies carried out in the early 1990s the total surface area on buildings available for photovoltaics amounts to an enormous potential of 1,000 km-2, which is equivalent to an electricity generating potential of 130 TWh (100 TWh on roofs and 30 TWh on facades), or 25% of Germany`s total electricity demand. The degree to which this potential will be realised in the long term will notably depend on whether convincing architectural solutions are found for integrating photovoltaic plants in roofs and facades. [Deutsch] Der Photovoltaikmarkt waechst weltweit seit Mitte der 80er Jahre um durchschnittlich 15% und liegt heute bei einer Jahresmodulproduktion ueber 100 MW{sub p}.

    2000-01-01

    An automated control and monitoring system for the new MIT high intensity epithermal neutron irradiation facility has been designed and constructed. The neutron beam is monitored with fission counters located at the periphery of the beam near the patient position. Control of the beam is accomplished with redundant Programmable Logic Controllers (PLCs). These industrial controllers open and close the three shutters of the Fission Converter Beam. The control system uses a series of robust components to assure that the prescribed fluence is delivered. This paper discusses the design and implementation of this system. (author)

    Buckley, Tamara R

    2017-09-12

    Intersectional approaches for understanding identity have gained momentum in the social sciences. Black adolescent males are often perceived as threatening, underachieving, and hypermasculine, which is reinforced through media outlets and psychological research that portray them as a monolith rather than a heterogeneous group with multiple intersecting identities. This cross-sectional study of 70 Black adolescent males between 14 and 18 years old simultaneously explores their race and gender identities and associations with self-concept (global and school). Results demonstrated that participants reported a combination of feminine and masculine gender roles, rather than hypermasculine. A canonical correlation analysis found that Black racial identity attitudes (RIAS-L) and gender roles simultaneously contributed to significant relationships with total and school self-concept. Study limitations and future directions for research and practice are discussed. © 2017 The Authors. Child Development © 2017 Society for Research in Child Development, Inc.

Iodine status was found as deficient, adequate, more than adequate and excessive in 2, 4, 19 and 25 schools, respectively. Seventy seven percent of table salt samples showed adequate iodine content (20-40 ppm), while 9.6% of the samples had low iodine content (school were positively correlated with medians of body mass index (BMI) by using the standard deviation score (SDS) (r = 0.47; p school were negatively correlated with stunting prevalence (r = -0.39; p = 005) and social gap index (r = -0.36; p coexistence between the two extremes of iodine intake (insufficient and excessive). To our knowledge, the observed positive correlation between UIC and overweight and obesity has not been described before, and could be explained by the availability and consumption of snack food rich in energy and iodized salt.

    Helicobacter sp. MIT 01-6451 has been detected in SPF mice kept in Japan. To characterize strain MIT 01-6451, its infection route during fetal and neonatal life and effects on pregnancy were investigated using immunocompetent and immunodeficient mouse strains (BALB/c, C57BL/6, and SCID). MIT 01-6451 was detected in the uterus, vagina, and mammary glands of 50% of infected SCID mice, whereas these tissues were all negative in immunocompetent mice. No fetal infections with MIT 01-6451 were detected at 16-18 days after pregnancy in any mouse strain. In newborn mice, MIT 01-6451 was detected in intestinal tissue of C57BL/6 and SCID mice at 9-11 days after birth, but not in BALB/c mice. The IgA and IgG titers to MIT 01-6451 in sera of C57BL/6 female mice were significantly lower than those of BALB/c mice. Although no significant differences in the number of newborns per litter were observed between MIT 01-6451-infected and MIT 01-6451-free dams, the birth rate was lower in infected SCID mice than in control SCID mice. The present results indicated that MIT 01-6451 infects newborn mice after birth rather than by vertical transmission to the fetus via the placenta and that MIT 01-6451 infection shows opportunistically negative effects on the birth rate. In addition, the maternal immune response may affect infection of newborn mice with MIT 01-6451 through breast milk.

    Versorgungsregister dienen der Erfassung des Einsatzes und der Wirksamkeit von Therapien unter realen Versorgungsbedingungen und sind als Basis einer evidenzbasierten Gesundheitsversorgung unverzichtbar. Das deutsche Neurodermitis-Register TREATgermany wurde als weltweit erstes Register für Patienten mit schwerer Neurodermitis 2011 initiiert. Erwachsene mit schwerer Neurodermitis (aktuelle/frühere antientzündliche Systemtherapie und/oder objektiver SCORAD ≥ 40) werden über einen Zeitraum von 24 Monaten prospektiv beobachtet. Anhand validierter Erhebungsinstrumente werden die klinische Erkrankungsschwere (EASI, SCORAD), Lebensqualität (DLQI), Symptome, globale Erkrankungsschwere sowie die Patientenzufriedenheit erfasst und die durchgeführten Therapien dokumentiert. Die vorliegende Analyse beschreibt die Charakteristika, Therapiewahl und Wirksamkeit der eingesetzten antiinflammatorischen Systemtherapien der bis Oktober 2014 eingeschlossenen Patienten. An fünf Zentren wurden insgesamt 78 Patienten (Durchschnittsalter 39 Jahre, 61 % männlich) eingeschlossen. Bei den Patienten besteht eine hohe Inanspruchnahme ambulanter und stationärer Leistungen. Ciclosporin war das am häufigsten eingesetzte Systemtherapeutikum und zeigte die höchste klinische Effektivität (EASI-50-Ansprechrate 51 %; EASI-75-Ansprechrate 34 % nach zwölfwöchiger Therapie). Azathioprin, Methotrexat (MTX), Prednisolon oral, Mycophenolat, Alitretinoin und Leflunomid wurden ebenfalls bei einzelnen Patienten eingesetzt. Die vorliegende Registerauswertung gibt wichtige Hinweise zur derzeitigen Versorgung von Erwachsenen mit schwerer Neurodermitis in Deutschland, dokumentiert die hohe Erkrankungslast, den Nutzen vorhandener Therapien und den Bedarf an weiteren, effektiven und in der Langzeitanwendung sicheren Therapieoptionen. © 2017 Deutsche Dermatologische Gesellschaft (DDG).

    Alitretinoin ist die einzige zugelassene Behandlung für schweres chronisches Handekzem (CHE), das refraktär gegenüber potenten topischen Corticosteroiden ist. Bei dieser Studie (FUGETTA) wurde die Wirksamkeit von leitliniengerecht angewendetem oralem Alitretinoin sowie dessen Einfluss auf die Lebensqualität (LQ) bei Patienten mit schwerem refraktärem CHE beurteilt. Multizentrische, offene, nichtinterventionelle Beobachtungsstudie, durchgeführt in Deutschland. Die Patienten wurden nach Ermessen ihres behandelnden Arztes mit Alitretinoin 10 mg oder 30 mg einmal täglich über maximal 24 Wochen behandelt. Die Wirksamkeit wurde anhand des Physician Global Assessment (PGA) und des Dermatology Life Quality Index (DLQI) bewertet. Zudem wurden unerwünschte Ereignisse (UE) erfasst. Die Studienpopulation bestand aus 658 Patienten (30 mg: n = 581; 10 mg: n = 77). Bei Beobachtungsbeginn litten die meisten Patienten (83 %) gemäß PGA an einem schweren CHE. Bei Beobachtungsende war das Handekzem bei 48 % der Patienten gemäß PGA vollständig oder fast vollständig abgeheilt (30 mg: 49 %; 10 mg: 43 %). Die mittlere Verbesserung des DLQI-Scores in Woche 24 betrug 58 % (30 mg: mittlere [SD] Veränderung gegenüber dem Ausgangswert -10,4 [8,04]) und 70 % (10 mg: mittlere [SD] Veränderung gegenüber dem Ausgangswert -10,8 [7,29]). Die Gesamtinzidenz von NW war niedrig und in den beiden Gruppen ähnlich. Alitretinoin führte zu einer schnellen, deutlichen Verbesserung der LQ bei Patienten mit schwerem CHE. © 2016 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

    The Idaho National Engineering Laboratory (INEL) has initiated the design and development of a novel pulsed accelerator-based, active interrogation concept. The proposed concept, referred to as the Material Identification Technology (MIT), enables rapid (between accelerator pulses), non-destructive, elemental composition analysis of both nuclear and non-nuclear materials. Applications of this technique include material monitoring in support of counter-proliferation activities, such as export controls (at domestic and international inspection locations), SNM controls, nuclear weapon dismantlement, and chemical weapon verification. Material Identification Technology combines a pulsed, X-ray source (an electron accelerator) and a gamma detection system. The accelerator must maximize neutron production (pulse width, beam current, beam energy, and repetition rate) and minimize photon dose to the object. Current available accelerator technology can meet these requirements. The detection system must include detectors which provide adequate gamma energy resolution capability, rapid recovery after the initial X-ray interrogation pulse, and multiple single gamma event detection between accelerator pulses. Further research is required to develop the detection system. This report provides the initial feasibility assessment of the MIT concept

    The MIT-Bates South Hall Ring construction project is now nearly complete. At this time the Energy Compression System, the SHR Injection Line and the South Hall Ring itself are complete. The SHR Extraction Line is complete but has not been connected to the ring. Commissioning with beam of the completed beam lines has been started. The MIT-Bates South Hall Ring (SHR) is an electron storage ring used with the 1 GeV Bates electron accelerator to increase the effective duty factor and luminosity. A beam can be stored for use with an internal target, thus allowing for high duty factor, high luminosity experiments. External beams with high duty factor can be obtained using resonant extraction. The new systems associated with the SHR include the Energy Compression System (ECS), the Injection line, and the Extraction line. The authors have commissioned the ECS, the new injection line and the SHR without RF. This includes transporting beam, measuring beam phase space parameters using critical injection elements including a high voltage electrostatic septum, a fast beam kicker, and storing a beam in the SHR

    Given the lack of a standardized approach to medical student global health predeparture preparation, we evaluated an in-person, interactive predeparture orientation (PDO) at the University of California Los Angeles (UCLA) to understand program strengths, weaknesses, and areas for improvement. We administered anonymous surveys to assess the structure and content of the PDO and also surveyed a subset of students after travel on the utility of the PDO. We used Fisher's exact test to evaluate the association between prior global health experience and satisfaction with the PDO. One hundred and five students attended the PDO between 2010 and 2014 and completed the survey. One hundred and four students (99.0%) reported learning new information. Major strengths included faculty mentorship (N = 38, 19.7%), opportunities to interact with the UCLA global health community (N = 34, 17.6%), and sharing global health experiences (N = 32, 16.6%). Of students surveyed after their elective, 94.4% (N = 51) agreed or strongly agreed that the PDO provided effective preparation. Students with prior global health experience found the PDO to be as useful as students without experience (92.7% versus 94.4%, P = 1.0). On the basis of these findings, we believe that a well-composed PDO is beneficial for students participating in global health experiences and recommend further comparative studies of PDO content and delivery. © The American Society of Tropical Medicine and Hygiene.

    The microtubule interacting and trafficking (MIT) domain is a small protein module that is conserved in proteins of diverged function, such as Vps4, spastin and sorting nexin 15 (SNX15). The molecular function of the MIT domain is protein-protein interaction, in which the domain recognizes peptides containing MIT-interacting motifs. Recently, we identified an evolutionarily related domain, 'variant' MIT domain at the N-terminal region of the microtubule severing enzyme katanin p60. We found that the domain was responsible for binding to microtubules and Ca(2+). Here, we have examined whether the authentic MIT domains also bind Ca(2+). We found that the loop between the first and second α-helices of the MIT domain binds a Ca(2+) ion. Furthermore, the MIT domains derived from Vps4b and SNX15a showed phosphoinositide-binding activities in a Ca(2+)-dependent manner. We propose that the MIT domain is a novel membrane-associating domain involved in endosomal trafficking.

  4. Parallelization Experience with Four Canonical Econometric Models Using ParMitISEM

    Directory of Open Access Journals (Sweden)

    Nalan Baştürk

    2016-03-01

    Full Text Available This paper presents the parallel computing implementation of the MitISEM algorithm, labeled Parallel MitISEM. The basic MitISEM algorithm provides an automatic and flexible method to approximate a non-elliptical target density using adaptive mixtures of Student-t densities, where only a kernel of the target density is required. The approximation can be used as a candidate density in Importance Sampling or Metropolis Hastings methods for Bayesian inference on model parameters and probabilities. We present and discuss four canonical econometric models using a Graphics Processing Unit and a multi-core Central Processing Unit version of the MitISEM algorithm. The results show that the parallelization of the MitISEM algorithm on Graphics Processing Units and multi-core Central Processing Units is straightforward and fast to program using MATLAB. Moreover the speed performance of the Graphics Processing Unit version is much higher than the Central Processing Unit one.

  5. Multi-model Ensemble Regional Climate Projection of the Maritime Continent using the MIT Regional Climate Model

    In this study, the future change in precipitation due to global warming is investigated over the Maritime Continent using the MIT Regional Climate Model (MRCM). A total of nine 30-year projections under multi-GCMs (CCSM, MPI, ACCESS) and multi-scenarios of emissions (Control, RCP4.5, RCP8.5) are dynamically downscaled using the MRCM with 12km horizontal resolution. Since downscaled results tend to systematically overestimate the precipitation regardless of GCM used as lateral boundary conditions, the Parametric Quantile Mapping (PQM) is applied to reduce this wet bias. The cross validation for the control simulation shows that the PQM method seems to retain the spatial pattern and temporal variability of raw simulation, however it effectively reduce the wet bias. Based on ensemble projections produced by dynamical downscaling and statistical bias correction, a reduction of future precipitation is discernible, in particular during dry season (June-July-August). For example, intense precipitation in Singapore is expected to be reduced in RCP8.5 projection compared to control simulation. However, the geographical patterns and magnitude of changes still remain uncertain, suffering from statistical insignificance and a lack of model agreement.

    Obwohl Tätowierungen in den letzten Jahren außerordentlich beliebt geworden sind, wurde in der Literatur bisher nur über wenige Fälle schwerer Reaktionen berichtet, die zu einer malignen Transformation führten. Dies steht im Kontrast zu der praktisch unüberschaubaren Zahl an Tätowierungen weltweit. Die Zusammensetzung der für Tätowierungen verwendeten Farbstoffe variiert stark, und selbst gleiche Farbtöne können unterschiedliche Komponenten enthalten. Das Ziel unserer Studie war es zu untersuchen, auf welche Weise Tätowierungen möglicherweise Hautkrebs auslösen können. Wir berichten über den seltenen Fall einer 24-jährigen Frau, bei der sich sieben Monate nachdem sie eine Tätowierung auf dem Fußrücken erhalten hatte in unmittelbarer Nähe des verwendeten roten Farbstoffs ein Plattenepithelkarzinom entwickelte. Die Komplikationen begannen mit einer unspezifischen Schwellung. Die Läsion wurde histologisch untersucht. Die Zusammensetzung des inkorporierten Farbstoffs wurde mittels Rasterelektronenmikroskopie in Kombination mit energiedispersiver Elementanalyse analysiert. Zur weiteren Charakterisierung wurden Thermogravimetrie und Pulverdiffraktometrie eingesetzt. Der Tätowierungsfarbstoff enthielt hauptsächlich Bariumsulfat; Spuren von Al, S, Ti, P, Mg und Cl ließen sich ebenfalls nachweisen. Bei der Analyse zeigten sich Pigmentgranula unterschiedlicher Größe. In seltenen Fällen kann Tätowierungstinte karzinogene Effekte haben, die multifaktoriell zu sein scheinen. © 2016 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

  18. MiT family translocation renal cell carcinoma.

    Argani, Pedram

    2015-03-01

    The MiT subfamily of transcription factors includes TFE3, TFEB, TFC, and MiTF. Gene fusions involving two of these transcription factors have been identified in renal cell carcinoma (RCC). The Xp11 translocation RCCs were first officially recognized in the 2004 WHO renal tumor classification, and harbor gene fusions involving TFE3. The t(6;11) RCCs harbor a specific Alpha-TFEB gene fusion and were first officially recognized in the 2013 International Society of Urologic Pathology (ISUP) Vancouver classification of renal neoplasia. These two subtypes of translocation RCC have many similarities. Both were initially described in and disproportionately involve young patients, though adult translocation RCC may overall outnumber pediatric cases. Both often have unusual and distinctive morphologies; the Xp11 translocation RCCs frequently have clear cells with papillary architecture and abundant psammomatous bodies, while the t(6;11) RCCs frequently have a biphasic appearance with both large and small epithelioid cells and nodules of basement membrane material. However, the morphology of these two neoplasms can overlap, with one mimicking the other. Both of these RCCs underexpress epithelial immunohistochemical markers like cytokeratin and epithelial membrane antigen (EMA) relative to most other RCCs. Unlike other RCCs, both frequently express the cysteine protease cathepsin k and often express melanocytic markers like HMB45 and Melan A. Finally, TFE3 and TFEB have overlapping functional activity as these two transcription factors frequently heterodimerize and bind to the same targets. Therefore, on the basis of clinical, morphologic, immunohistochemical, and genetic similarities, the 2013 ISUP Vancouver classification of renal neoplasia grouped these two neoplasms together under the heading of "MiT family translocation RCC." This review summarizes our current knowledge of these recently described RCCs. Copyright © 2015 Elsevier Inc. All rights reserved.

An einem zweiten Kollektiv von 23 Patienten wurden Analysen des Phänotyps für alpha1-PI im Hinblick auf das Vorliegen von genetisch determinierten Mangelallelen vorgenommen. Hier zeigte sich kein signifikanter Unterschied zu einem Kontrollkollektiv von 19 gesunden Probanden. Die alpha1-PI Erniedrigung der IPP-Patienten ist signifikant und liegt unterhalb des Normalwertbereichs für die gesunde Population. Ein Mangel an alpha1-PI kann zur Aktivitätserhöhung der Proteasen und zum Umbau des Kollagengewebes führen. Möglicherweise kommt es zusammen mit einem lokal wirksamen Einflußfaktor schließlich zur dystrophen Kalzifikation. Die humangenetischen Untersuchungen sprechen nicht für eine genetische Determinierung des alpha1-PI-Mangels, sondern legen eine erworbene hepatische Störung nahe.

    The Harvard-MIT Research Program in Short-lived Radiopharmaceuticals was established in 1977 to foster interaction among groups working in radiopharmaceutical chemistry at Harvard Medical School, the Massachusetts Institute of Technology, and the Massachusetts General Hospital. To this was added a group at The Childrens Hospital. From these collaborations and building upon the special strengths of the participating individuals, laboratories and institutions, it was hoped that original approaches would be found for the design of new, clinically useful, radiolabeled compounds. The original thrust of this proposal included: (a) examination of the coordination chemistry of technetium as a basis for rational radiopharmaceutical design, (b) development of an ultrashort-lived radionuclide generator for the diagnosis of congenital heart disease in newborns, (c) synthesis of receptor-site-directed halopharmaceuticals, (d) improved facile labeling of complex molecules with positron-emitting radionuclides. The authors' 1986 proposal was oriented toward organs and disease, emphasizing radiolabeled agents that delineate specific functions and the distribution of receptors in brain, heart, and tumors. In 1989, they further refined their purposes and focused on two major aims: (a) synthesis and utilization of neutral technetium and rhenium complexes of high specific activity, and (b) development of new approaches to the radiolabeling of proteins, peptides, immunoglobulins, and their fragments. In 1992, the authors amended this proposal to concentrate their efforts on biologically active peptides and proteins for targeted radiodiagnosis and therapy

    Full Text Available The perception of the value of themselves as individuals is a very important outcome in childhood. The aim of this paper is to study the influence of specific domain self-perception on the self-esteem of school age children from Buenos Aires City/AR (CABA. The Self-Perception Profile for Children was administered to 219 children of both genders (mean age = 10.34; SD = 1.77 from a private school from CABA. Multiple lineal regression analysis were performed. School grade and sex differences were taken into account. The main predictor of self-esteem for the boys is the self-perception of physical appearance and for the girls the self-perception of social acceptance. Considering grade differences, the main predictor of self-esteem for children from third to fifth grade is the self-perception of physical appearance and for sixth and seventh graders the self-perception of social acceptance and behavior.

    The Micro Imaging Technology (MIT) 1000 Rapid Microbial Identification (RMID) System is a device that uses the principles of light scattering coupled with proprietary algorithms to identify bacteria after being cultured and placed in a vial of filtered water. This specific method is for pure culture identification of Listeria spp. A total of 81 microorganisms (55 isolates) were tested by the MIT 1000 System, of which 25 were Listeria spp. and 30 a variety of other bacterial species. In addition, a total of 406 tests over seven different ruggedness parameters were tested by the MIT 1000 System to determine its flexibility to the specifications stated in the MIT 1000 System User Guide in areas where they might be deviated by a user to shorten the test cycle. Overall, MIT concluded that the MIT 1000 System had an accuracy performance that should certify this Performance Test Method for the identification of Listeria spp. This report discusses the tests performed, results achieved, and conclusions, along with several reference documents to enable a higher understanding of the technology used by the MIT 1000 System.

    Experimental models of education that incorporate the mother tongue of immigrant children into the structure of their curricula constitute obvious cases-in-point for assessing the validity of bilingual or multilingual education for such children. The present case study of one such model, the so-called `Foyer Bicultural Education Project' of Brussels, is intended to shed some light on the relationship between formal mother-tongue training and the development of global language proficiency in minority-language children. Since this particular case-in-point involves three languages — Italian (the mother tongue), Flemish and French — it is especially interesting with regard to the validity of the so-called `interdependence principle', as formulated by Cummins (1979). The findings presented here confirm Cummins' principle that the development of literacy in the mother tongue is a determinant of global language proficiency in minority-language children.

    In Deutschland wenden 40-90 % aller Krebspatienten Methoden der komplementären and alternativen Medizin (KAM) an. Bis dato gibt es kein Datenmaterial zum Einsatz der KAM bei Melanompatienten. Das Ziel unserer Studie war es, Daten über den Gebrauch, die Informationsquellen und Ziele von Patienten mit metastasierendem Melanom zu erfassen. Einhundertsechsundfünfzig Patienten aus 25 Studienzentren nahmen an der DecOG-MM-PAL Multibasket Studie teil. Die beteiligten Personen wurden auch gebeten, an einer Nebenstudie teilzunehmen, die ihren Gebrauch von KAM erfassen sollte. Dazu wurde während der Behandlung ein standardisierter Fragebogen zu genau festgelegten Zeitpunkten ausgeteilt. Insgesamt gingen 55 Fragebögen von 32 (21 %) Melanompatienten ein. Von diesen gaben 17 (53 %) ein Interesse an KAM an, und sieben (22 %) machten von KAM Gebrauch. Die Hauptinformationsquellen (31 %) waren Familienmitglieder und Freunde, gefolgt von Ärzten (19 %). Die Hauptgründe für die Anwendung von KAM waren die Stärkung des Immunsystems (41 %) und des Körpers (34 %). Nahrungsergänzungsmittel (Vitamine und Spurenelemente) wurden am häufigsten angewendet (28 %). Eine relativ hohe Anzahl an Patienten mit metastasierendem Melanom machte trotz Teilnahme an einer klinischen Studie von KAM Gebrauch. Wechselwirkungen könnten durch biologisch basierte KAM auftreten, und hier besonders bei immunmodulierenden KAM- Strategien. Um Risiken zu vermeiden, sollte die Kommunikation zwischen den Ärzten und den Patienten verbessert werden. © 2016 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

  11. Conceptualizing In-service Secondary School Science Teachers' Knowledge Base for Promoting Understanding about the Science of Global Climate Change

    Bhattacharya, Devarati

    Efforts to adapt and mitigate the effects of global climate change (GCC) have been ongoing for the past two decades and have become a major global concern. However, research and practice for promoting climate literacy and understanding about GCC have only recently become a national priority. The National Research Council (NRC), has recently emphasized upon the importance of developing learners' capacity of reasoning, their argumentation skills and understanding of GCC (Framework for K-12 Science Education, National Research Council, 2012). This framework focuses on fostering conceptual clarity about GCC to promote innovation, resilience, and readiness in students as a response towards the threat of a changing environment. Previous research about teacher understanding of GCC describes that in spite of the prevalent frameworks like the AAAS Science Literacy Atlas (AAAS, 2007) and the Essential Principles for Climate Literacy (United States Global Climate Research Program, 2009; Bardsley, 2007), most learners are challenged in understanding the science of GCC (Michail et al., 2007) and misinformed perceptions about basic climate science content and the role of human activities in changing climate remain persistent (Reibich and Gautier, 2006). Our teacher participants had a rather simplistic knowledge structure. While aware of climate change, teacher participants lacked in depth understanding of how change in climate can impact various ecosystems on the Earth. Furthermore, they felt overwhelmed with the extensive amount of information needed to comprehend the complexity in GCC. Hence, extensive efforts not only focused on assessing conceptual understanding of GCC but also for teaching complex science topics like GCC are essential. This dissertation explains concept mapping, and the photo elicitation method for assessing teachers' understanding of GCC and the use of metacognitive scaffolding in instruction of GCC for developing competence of learners in this complex

    Suicidal behavior among adolescents is not a well-explored public health problem. Health policy decision-making on suicidal behavior needs reliable information on the prevalence of suicidal ideation (SI) and its associated risk factors to produce health promotion and prevention programs. The Global School Health Survey is a self-administered survey done on a random probabilistic sample among students of the 7th, 8th, and 9th grades in the Lara State, Venezuela, school period 2003 to 2004. Point prevalence of SI and associated factors were included and the odds (OR) of having SI was calculated given selected factors. Two-thousand seventy (2070) respondents, of which 13.5 % reported having SI in the last 12 months, and in females more than males (14.6% vs. 11.7%). The OR for SI, according to an associated risk factor, were among (a) females: age > or = 14 years (2.2), worries (3.42), loneliness (8.8), ever had sexual intercourse (5.58), alcohol (8.43) and (b) males: having only one or non close friends (3.69), alcohol (12.36), ever had sexual intercourse (2.73). Behavioral risk factors are relatively new in the field of surveillance systems; therefore, results on SI should be cautiously taken into consideration and a wide discussion should be encouraged as we learn how to best use the results for health promotion and disease prevention.

    The goals of this study were to identify the proportion of early adolescents in southern South America who were injured in the past year, to identify risk behaviours and other exposures associated with injuries, and to evaluate the most common types and causes of injury in this population. We used complex samples analysis to examine cross-sectional data from more than 35,000 students from all four countries in South America that participated in the Global School-based Student Health Survey (GSHS) in 2012-2013. The proportion of students reporting at least one injury in the past year that required medical treatment or caused at least one full day of missed school or usual activities was 27.1% in Argentina, 29.5% in Uruguay, 30.9% in Chile, and 36.8% in Bolivia. Significantly more boys than girls reported injuries. Injured students were more likely than non-injured students to report anxiety-induced insomnia, being physically attacked, being in a physical fight, and being lonely in the past year, and they were also more likely to report being bullied, using tobacco, drinking alcohol, and missing school in the past month. For both boys and girls, the most common type of injury reported was a broken bone or dislocated joint and the most common injury cause was the student falling. However, most students were not able to provide a specific answer to either question. The GSHS has been conducted in 100 low- and middle-income countries and territories around the world, and new waves of data collection are currently being planned and implemented. The utility of the injury data from the GSHS would be improved if the injury type and cause response items were updated to better capture information about self-harm, sports injuries, and other statistics that will provide a stronger foundation for evidence-based injury prevention interventions in adolescent populations.

    The future of all reactors will depend on whether they can be economically built and operated. One of the major impediments to new nuclear construction is the capital cost due in large part to the length of construction time and complexity of the plant. Pebble bed reactors offer the opportunity to reduce the complexity of the plant because the number of safety systems required is significantly reduced due to the inherent safety of the technology. However, because of its small size, the capital cost per kilowatt is likely to be large if traditional construction approaches are followed. This strongly suggests the need for innovative construction concepts to reduce the construction time and cost. MIT has proposed a modularity approach in which the plant is pre-built in space-frame type modules which are built in factories. These space frames would contain all the equipment contained in a given volume. Once equipment in the space frame is installed, the space frame would then be shipped to the site and assembled 'lego-style.' Studies presently underway have demonstrated the feasibility of the concept. Thermal stress analysis has been performed and an integrated design with the space frames has been developed. It is expected that this modularity approach will significantly shorten construction time and expense. This paper proposes a concept for further development, not a final design for the entire plant.

    The control and data system of the MIT Tara Tandem Mirror has worked successfully throughout the lifetime of the experiment (1983 through 1987). As the Tara project winds down, it is appropriate to summarize the lessons learned from the implementation and operation of the control and data system over the years and in its final form. The control system handled ∼2400 I/0 points in real time throughout the 5 to 10 minute shot cycle while the data system, in near real time, handled ∼1000 signals with a total of 5 to 7 Mbytes of data each shot. The implementation depended upon a consistent approach based on separating physics and engineering functions and on detailed functional diagrams with narrowly defined cross communication. This paper is a comprehensive treatment of the principal successes, residual problems, and dilemmas that arose from the beginning until the final hardware and software implementation. Suggestions for future systems of either similar size or of larger scale such as CIT are made in the conclusion. 11 refs., 1 fig

    Full Text Available Abstract Background Many studies examining the social correlates of tobacco use among adolescents fail to recognise theories of health behaviour and health promotion in their analysis. Using the Socio-Ecologiocal Model (SEM we assessed the demographic and social factors associated with current cigarette smoking among adolescents in Thailand. Method A secondary analysis of cross-sectional data from the Thai Global Youth Tobacco Survey (Thai GYTS 2005 was analysed to obtain prevalence of selected attributes and assess factors associated with current cigarette smoking. Current cigarette smoking was defined as having smoked a cigarette, even a single puff, in the last 30 days. Logistic regression was conducted to estimate the level of association between the explanatory variables and current smoking. Results Of the 18,368 respondents, 22.0% males and 5.2% females reported being current smokers (p Conclusion Current cigarette smoking was associated with male gender, smoking parents or closest peers. Perception that smoking was harmful to health was associated with less likelihood of being a current smoker.

    Cardiovascular magnetic resonance imaging (CMR) has become a routinely used imaging modality for congenital heart disease. A CMR examination allows the assessment of thoracic anatomy, global and regional cardiac function, blood flow in the great vessels and myocardial viability and perfusion. In the clinical routine cardiovascular MRI is mostly performed at field strengths of 1.5 Tesla (T). Recently, magnetic resonance systems operating at a field strengths of 3 T became clinically available and can also be used for cardiovascular MRI. The main advantage of CMR at 3 T is the gain in the signal-to-noise ratio resulting in improved image quality and/or allowing higher acquisition speed. Several further differences compared to MRI systems with lower field strengths have to be considered for practical applications. This article describes the impact of CMR at 3 T in patients with congenital heart disease by meanings of methodical considerations and case studies. (orig.)

    Susceptibility to smoke has been recognized as a strong predictor of smoking experimentation and taking up regular smoking habit. The identification of smoking susceptible individuals and its determinants is important in the efforts to reduce future smoking prevalence. The aims of this study are to estimate prevalence of susceptibility to smoke among adolescents, and identify factors associated with it. Cross sectional data was obtained from Global Youth Tobacco Survey conducted in three cities of Pakistan in year 2004. Study population consisted of students in grades, 8th, 9th, and 10th; aged 13 to 15 years. Secondary analysis using univariate and multivariate logistic regression analyses were performed to estimate the associations between smoking susceptibility and co-variates. Descriptive statistics were reported in proportions, and adjusted odds ratios with 95% confidence interval were used to report logistic regression analyses. Approximately 12% of nonsmoking students were found susceptible to smoking. Students, who were females (OR = 1.53, 95% CI [1.24-1.89]); whose parents (OR = 1.64, 95% CI [1.35-1.99]); or close friend smoked (OR = 2.77, 95% CI [2.27- 3.40]) were more susceptible to cigarette smoking. Students who had good knowledge about harmful effects of smoking (OR = 0.54, 95% CI [0.43-0.69]); and had access to anti-smoking media (OR = 0.73, 95% CI [0.59-0.89]) were less likely to be susceptible to smoking. Students who were females, had smoking parents, friends or exposure to newspaper/magazines cigarette marketing, were more susceptible to cigarette smoking among Pakistani adolescents. While knowledge of harmful effects of smoking and access to anti-smoking media served as protective factors against susceptibility to smoking.

    Iron (Fe) is an essential micronutrient for plant growth and development, and its reduced bioavailability strongly impairs mitochondrial functionality. In this work, the metabolic adjustment in the rice (Oryza sativa) mitochondrial Fe transporter knockdown mutant (mit-2) was analysed. Biochemical characterization of purified mitochondria from rice roots showed alteration in the respiratory chain of mit-2 compared with wild-type (WT) plants. In particular, proteins belonging to the type II alternative NAD(P)H dehydrogenases accumulated strongly in mit-2 plants, indicating that alternative pathways were activated to keep the respiratory chain working. Additionally, large-scale changes in the transcriptome and metabolome were observed in mit-2 rice plants. In particular, a strong alteration (up-/down-regulation) in the expression of genes encoding enzymes of both primary and secondary metabolism was found in mutant plants. This was reflected by changes in the metabolic profiles in both roots and shoots of mit-2 plants. Significant alterations in the levels of amino acids belonging to the aspartic acid-related pathways (aspartic acid, lysine, and threonine in roots, and aspartic acid and ornithine in shoots) were found that are strictly connected to the Krebs cycle. Furthermore, some metabolites (e.g. pyruvic acid, fumaric acid, ornithine, and oligosaccharides of the raffinose family) accumulated only in the shoot of mit-2 plants, indicating possible hypoxic responses. These findings suggest that the induction of local Fe deficiency in the mitochondrial compartment of mit-2 plants differentially affects the transcript as well as the metabolic profiles in root and shoot tissues. © The Author 2015.

    We present preliminary results from recent measurements of the proton, neutron and deuterium electro-magnetic form factors obtained by the BLAST collaboration at the MIT/Bates Linear Accelerator Facility. BLAST (Bates Large Acceptance Spectrometer Toroid) is a large-acceptance multi-purpose detector dedicated to studies of exclusive spin-dependent electron scattering from internal polarized targets. BLAST makes use of stored electron beam currents in excess of 150 mA with a 60-70% polarization. The electron beam is let through a 15 mm diameter, 60 cm long open-ended storage cell which is fed with ultra-pure, high-polarization H1,D1 gas from an Atomic Beam Source. The target polarization can be rapidly reversed between different vector and tensor target states, thus minimizing systematic uncertainties. The target spin can be oriented to any in-plane direction via a set of Helmholtz coils. Target polarizations in the storage cell of up to 80% (vector) and 70% (tensor) have been routinely achieved over a period of several months. Our data on the D-vector(e-vector,e'n) reaction off vector polarized deuterium allow for a unique extraction of the neutron charge form factor G E n . At same time, complementary measurements of G M n , T20 and the spin-dependent nucleon momentum distributions in deuterium are obtained via the D-vector(e-vector,e'), D (e-vector,e'd) and D (e-vector,e'p) reactions. In addition, BLAST data on vector polarized hydrogen will provide novel measurements of the GE/GM form-factor ratio on the proton as well as of the spin-dependent electro-excitation of the Δ(1232) resonance. Such comprehensive program on few body physics is now well underway and preliminary data will be presented

    Der übermäßige oder unkritische weltweite Einsatz von Antibiotika in der Medizin hat die Ausbreitung von Antibiotikaresistenzen beschleunigt. In einigen Bereichen sind viele Antibiotika bei bakteriellen Infektionen, die zuvor noch gut auf antibakterielle Wirkstoffe reagierten, mittlerweile wirkungslos geworden. Dermatologen/Venerologen setzten orale und topische Antibiotika bei der Behandlung von Acne vulgaris routinemäßig ein, obwohl Akne weder eine infektiöse Erkrankung ist noch alleine durch das Propionibacterium getriggert wird. Vielmehr ist sie eine komplexe, chronische entzündliche Hauterkrankung, die durch verschiedene pathogenetische Faktoren wie follikuläre Hyperkeratose, erhöhter Sebumproduktion, bakterielle Proliferation und Entzündung zustande kommt. Folglich sollte eine erfolgreiche Therapie auf die Bekämpfung verschiedener pathogenetischer Faktoren und nicht nur auf die von Propionibacterium acnes abzielen. Daher wurden topische Retinoide und Benzoylperoxid als Mittel der ersten Wahl definiert. Monotherapien mit lokalen Antibiotika sollten insgesamt vermieden werden. Systemische Antibiotika der Tetrazyklin-Gruppe haben bei bestimmen Krankheitsstadien ihren Sinn, ihre Wirkung könnte aber eher auf der antientzündlichen als auf der antibiotischen Reaktion beruhen. Gesundheitsbehörden ermahnen alle Gesundheitsdienstleister, den Einsatz von Antibiotika einzuschränken. Das Nutzen-Risiko-Verhältnis muss bei der Entscheidung für oder gegen eine antibiotische Therapie bei einem einzelnen Patienten immer auch in Bezug auf das öffentliche Interesse am Erhalt der Wirksamkeit von Antibiotika abgewogen werden. Im Folgenden werden das aktuelle Krankheitskonzept zu Acne vulgaris und die sich daraus ableitenden Konsequenzen für den Einsatz von Antibiotika vorgestellt. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

    Full Text Available Dieser Beitrag zeigt die Relevanz der Soziologie Bourdieus für die Stadtforschung auf, indem er Bourdieus Frühwerk zu Macht, Raum und Urbanisierung im Béarn und Algerien aufgreift und es mit seinem Spätwerk verknüpft, in welchem er das soziale Leiden in der französischen Metropole analysiert. Es wirft ein Schlaglicht auf die vier übergreifenden Prinzipien, die Bourdieus Forschungspraxis antreiben und eine fruchtbare Anleitung für die Stadtforschung sein können: den Bachelardschen Imperativ des erkenntnistheoretischen Bruchs und der erkenntnistheoretischen Wachsamkeit; die Webersche Aufforderung zur dreifachen Historisierung des Handelnden (Habitus, der Welt (sozialer Raum, wovon das soziale Feld lediglich einen Untertypus darstellt und der Kategorien des Analytikers (erkenntnistheoretische Reflexivität; den Leibnizschen-Durkheimschen Vorschlag, eine topologische Denkweise zu nutzen, um den Wechselbeziehungen zwischen symbolischem, sozialem und physischem Raum nachzuspüren; sowie das Cassirersche Moment, das uns dazu anhält, die konstitutive Wirksamkeit symbolischer Strukturen zur Kenntnis zu nehmen. Ich möchte zudem auf drei Fallstricke hinweisen, die eine Stadtforschung auf den Spuren Bourdieus tunlichst vermeiden sollte: die Fetischisierung von Konzepten; die Verlockung, sich der Sprache Bourdieus zu bedienen („speaking Bourdieuse“, ohne die Forschungsschritte, die die Bourdieuschen Begriffe verlangen, tatsächlich durchzuführen; sowie das zwanghafte Überstülpen seines Theorierahmens als Ganzes auch in Fällen, in denen es produktiver wäre, einzelne Bausteine zu übertragen.

    The MIT Haystack Observatory Undergraduate Research Initiative is an NSF- funded program aimed at involving undergraduate students in active radio astronomical research. The project has two major thrusts - students get hands-on experience using a small radio telescope that has been developed at Haystack and which will be provided as a low cost kit early next year. Beta versions of this telescope are being built for a select group of institutions. The second component is a research experience with the Haystack 37-m telescope. Use of the 37-m telescope has ranged from classroom demonstrations to original research projects. The Small Radio Telescope (SRT) project consists of a 2m dish with a 1420 MHz receiver. The antenna has a two axis mount that provides full sky coverage. The telescope is intended to provide students and faculty with an introduction to radio astronomy and instrument calibration. Observations of the sun and the galactic HI line are possible with the current version of this telescope. The 37-m telescope program is aimed at providing students with a research experience that can result in publishable results. The telescope has also been used in providing students with an introduction to the scope of radio astronomical data including continuum and spectral line observations. Classroom demonstrations have also been tested with non-science majors. Extensive supporting materials for the project have been developed on the world wide web. These include a radio astronomy tutorial, hardware and software information about both telescopes and project descriptions. We also provide curriculum suggestions to aid faculty incorporate radio astronomy into their courses.

    The alcohol oxidase 1 (AOX1) promoter (P AOX1) of Pichia pastoris is the most powerful and commonly used promoter for driving protein expression. However, mechanisms regulating its transcriptional activity are unclear. Here, we identified a Zn(II)2Cys6-type methanol-induced transcription factor 1 (Mit1) and elucidated its roles in regulating PAOX1 activity in response to glycerol and methanol. Mit1 regulated the expression of many genes involved in methanol utilization pathway, including AOX1, but did not participate in peroxisome proliferation and transportation of peroxisomal proteins during methanol metabolism. Structural analysis of Mit1 by performing domain deletions confirmed its specific and critical role in the strict repression of P AOX1 in glycerol medium. Importantly, Mit1, Mxr1, and Prm1, which positively regulated P AOX1 in response to methanol, were bound to P AOX1 at different sites and did not interact with each other. However, these factors cooperatively activated P AOX1 through a cascade. Mxr1 mainly functioned during carbon derepression, whereas Mit1 and Prm1 functioned during methanol induction, with Prm1 transmitting methanol signal to Mit1 by binding to the MIT1 promoter (P MIT1), thus increasingly expressing Mit1 and subsequently activating P AOX1. © 2016 by The American Society for Biochemistry and Molecular Biology, Inc.

    A largely unaddressed issue in lower income countries and the Philippines, in particular, is the role of alcohol marketing and its potential link to early alcohol use among youth. This study examines the associations between exposures to alcohol marketing and Filipino youths' drinking prevalence and drunkenness. Cross-sectional analyses were used to examine the Global School-based Student Health Survey (GSHS) conducted in Philippines (2011). The self-administered questionnaires were completed by students primarily 13 to 16 years of age (N = 5,290). Three statistical models were computed to test the associations between alcohol marketing and alcohol use, while controlling for possible confounding factors. Alcohol marketing, specifically through providing free alcohol through a company representative, was associated with drunkenness (AOR: 1.84; 95% CI=1.06-3.21) among youths after controlling for demographic and psychosocial characteristics, peer environment, and risky behaviors. In addition, seeing alcohol ads in newspapers and magazines (AOR: 1.65, 95% CI=1.05-2.58) and seeing ads at sports events, concerts or fairs (AOR: 1.50, 95% CI =1.06-2.12) were significantly associated with increased reports of drunkenness. There are significant associations between alcohol marketing exposure and increased alcohol use and drunkenness among youth in the Philippines. These findings highlight the need to put policies into effect that restrict alcohol marketing practices as an important prevention strategy for reducing alcohol use and its dire consequences among vulnerable youth.

    Full Text Available Targeting the weekend to promote physical activity (PA in children seems to be promising given that they tend to be less physically active and, particularly, as the age-related decline in PA is more marked during weekends. Considering the ambiguity of why children are not able to maintain their PA level on weekends, the aim of the present study was to objectively investigate differences in children’s spatial PA patterns between week and weekend days using the combination of Global Positioning System (GPS and accelerometry. Seventy-four second graders (aged 7–9 years and 98 sixth graders (aged 11–14 years wore an accelerometer and GPS sensor for seven consecutive days to determine where children spend time and engage in PA. Time-matched accelerometer and GPS data was mapped with a geographic information system and multilevel analyses accounting for the hierarchical structure of the data were conducted. Differences between weekdays and weekends regarding the total time spent and the absolute and relative level of PA in various settings were found in both age groups. The findings support previous research pointing to the importance of targeting weekend PA, especially when children grow older. Future interventions should encourage children to use outdoor spaces more frequently on weekends, rather than stay at home, and to commute actively to destinations other than school.

    The mechanism of iron (Fe) uptake in plants has been extensively characterized, but little is known about how Fe transport to different subcellular compartments affects Fe localization in rice seed. Here, we discuss the characterization of a rice vacuolar Fe transporter 2 (OsVIT2) T-DNA insertion line (osvit2) and report that the knockdown of OsVIT2 and mitochondrial Fe transporter (MIT) expression affects seed Fe localization. osvit2 plants accumulated less Fe in their shoots when grown under normal or excess Fe conditions, while the accumulation of Fe was comparable to that in wild-type (WT) plants under Fe-deficient conditions. The accumulation of zinc, copper, and manganese also changed significantly in the shoots of osvit2 plants. The growth of osvit2 plants was also slow compared to that of WT plants. The concentration of Fe increased in osvit2 polished seeds. Previously, we reported that the expression of OsVIT2 was higher in MIT knockdown (mit-2) plants, and in this study, the accumulation of Fe in mit-2 seeds decreased significantly. These results suggest that vacuolar Fe trafficking is important for plant Fe homeostasis and distribution, especially in plants grown in the presence of excess Fe. Moreover, changes in the expression of OsVIT2 and MIT affect the concentration and localization of metals in brown rice as well as in polished rice seeds.

    2010-12-01

    The Caenorhabditis elegans mitochondrial (Mit) mutants have disrupted mitochondrial electron transport chain (ETC) functionality, yet, surprisingly, they are long lived. We have previously proposed that Mit mutants supplement their energy needs by exploiting alternate energy production pathways normally used by wild-type animals only when exposed to hypoxic conditions. We have also proposed that longevity in the Mit mutants arises as a property of their new metabolic state. If longevity does arise as a function of metabolic state, we would expect to find a common metabolic signature among these animals. To test these predictions, we established a novel approach monitoring the C. elegans exometabolism as a surrogate marker for internal metabolic events. Using HPLC-ultraviolet-based metabolomics and multivariate analyses, we show that long-lived clk-1(qm30) and isp-1(qm150) Mit mutants have a common metabolic profile that is distinct from that of aerobically cultured wild-type animals and, unexpectedly, wild-type animals cultured under severe oxygen deprivation. Moreover, we show that 2 short-lived mitochondrial ETC mutants, mev-1(kn1) and ucr-2.3(pk732), also share a common metabolic signature that is unique. We show that removal of soluble fumarate reductase unexpectedly increases health span in several genetically defined Mit mutants, identifying at least 1 alternate energy production pathway, malate dismutation, that is operative in these animals. Our study suggests long-lived, genetically specified Mit mutants employ a novel metabolism and that life span may well arise as a function of metabolic state.

    Full Text Available This paper presents the R package MitISEM (mixture of t by importance sampling weighted expectation maximization which provides an automatic and flexible two-stage method to approximate a non-elliptical target density kernel - typically a posterior density kernel - using an adaptive mixture of Student t densities as approximating density. In the first stage a mixture of Student t densities is fitted to the target using an expectation maximization algorithm where each step of the optimization procedure is weighted using importance sampling. In the second stage this mixture density is a candidate density for efficient and robust application of importance sampling or the Metropolis-Hastings (MH method to estimate properties of the target distribution. The package enables Bayesian inference and prediction on model parameters and probabilities, in particular, for models where densities have multi-modal or other non-elliptical shapes like curved ridges. These shapes occur in research topics in several scientific fields. For instance, analysis of DNA data in bio-informatics, obtaining loans in the banking sector by heterogeneous groups in financial economics and analysis of education's effect on earned income in labor economics. The package MitISEM provides also an extended algorithm, 'sequential MitISEM', which substantially decreases computation time when the target density has to be approximated for increasing data samples. This occurs when the posterior or predictive density is updated with new observations and/or when one computes model probabilities using predictive likelihoods. We illustrate the MitISEM algorithm using three canonical statistical and econometric models that are characterized by several types of non-elliptical posterior shapes and that describe well-known data patterns in econometrics and finance. We show that MH using the candidate density obtained by MitISEM outperforms, in terms of numerical efficiency, MH using a simpler

Mit1 regulated the expression of many genes involved in methanol utilization pathway, including AOX1, but did not participate in peroxisome proliferation and transportation of peroxisomal proteins during methanol metabolism. Structural analysis of Mit1 by performing domain deletions confirmed its specific and critical role in the strict repression of PAOX1 in glycerol medium. Importantly, Mit1, Mxr1, and Prm1, which positively regulated PAOX1 in response to methanol, were bound to PAOX1 at different sites and did not interact with each other. However, these factors cooperatively activated PAOX1 through a cascade. Mxr1 mainly functioned during carbon derepression, whereas Mit1 and Prm1 functioned during methanol induction, with Prm1 transmitting methanol signal to Mit1 by binding to the MIT1 promoter (PMIT1), thus increasingly expressing Mit1 and subsequently activating PAOX1.

    2013-01-01

    Background A largely unaddressed issue in lower income countries and the Philippines, in particular, is the role of alcohol marketing and its potential link to early alcohol use among youth. This study examines the associations between exposures to alcohol marketing and Filipino youths’ drinking prevalence and drunkenness. Methods Cross-sectional analyses were used to examine the Global School-based Student Health Survey (GSHS) conducted in Philippines (2011). The self-administered questionnaires were completed by students primarily 13 to 16 years of age (N = 5290). Three statistical models were computed to test the associations between alcohol marketing and alcohol use, while controlling for possible confounding factors. Results Alcohol marketing, specifically through providing free alcohol through a company representative, was associated with drunkenness (AOR: 1.84; 95% CI = 1.06–3.21) among youths after controlling for demographic and psychosocial characteristics, peer environment, and risky behaviors. In addition, seeing alcohol ads in newspapers and magazines (AOR: 1.65, 95% CI = 1.05–2.58) and seeing ads at sports events, concerts or fairs (AOR: 1.50, 95% CI = 1.06–2.12) were significantly associated with increased reports of drunkenness. Conclusions There are significant associations between alcohol marketing exposure and increased alcohol use and drunkenness among youth in the Philippines. These findings highlight the need to put policies into effect that restrict alcohol marketing practices as an important prevention strategy for reducing alcohol use and its dire consequences among vulnerable youth.

    Mental health and injury are neglected public health issues especially in low-income nations. The objective of the study was to determine the prevalence and socio-demographic correlates for serious injury in the last 12 months. The study used data of the 2007 Djibouti Global School-based Health Survey. Logistic regression analysis was used to establish associations. Of the 1, 777 respondents, 61.1% (63.2% males and 57.8% females) reported having sustained serious injury (SSI). Compared to participants who were not bullied, those who reported being bullied 3-9 days per month were more likely to have sustained serious injury in the last 12 months (AOR = 1.27; 95% CI [1.06, 1.52] for 3-5 days of bullying victimization per month, and AOR = 3.19; 95% CI [2.28, 4.47] for 6-9 days per month. Adolescents who were engaged in physical fighting were 47% (AOR = 1.47, 95% CI [1.40, 1.55] more likely to have sustained serious injury compared to those who were not engaged in the fighting. Meanwhile, adolescents who used substances (cigarettes, other forms of tobacco or drugs) were 30% (AOR = 1.30, 95% CI [1.19, 1.42]) more likely to have sustained serious injury compared to those who did not use substances. Serious injury is common among adolescents in Djibouti, and we suggest that health workers attending to injured adolescents explore the patients' psycho-social environment. Further, we suggest longitudinal studies where reduction of substance use and bullying may be assessed if they have an impact in reducing serious injury among adolescents.

    Scientific evidence on all aspects of smoking amongst youth is very important for designing appropriate interventions to reduce smoking among this vulnerable population. This paper describes current access to antismoking information among school children aged 13 to 15 years in Vietnam in 2014 and examines its potential impact on preventing smoking initiation. The data used in this paper were obtained from the 2014 Global Youth Tobacco Survey (GYTS) in Vietnam. Students were asked questions about their level of awareness of anti-smoking information from various sources in the past 30 days and about lessons in school regarding the dangers of tobacco use during the last 12 months. Those who have never smoked were asked "whether or not they thought about avoiding cigarettes because of health warnings on cigarette packages" and answers were analyzed in combination with data on access to anti-smoking information from other sources. The prevalence of exposure to antismoking campaigns was high among school children in Viet Nam: 55.3% of current smokers reported thoughts of smoking cessation because of health warnings on cigarette packages; 60.5% of never smokers avoided initiating smoking because of the same health warnings. The potential impact of graphic health warnings to prevent school-aged children from smoking initiation would be stronger if there was concurrent access to anti-smoking programs on the dangers of tobacco use in schools. However, school education for tobacco prevention and control has not been as strong as expected. A more comprehensive school curriculum on tobacco prevention and control is recommended to reinforce antismoking messages among school children.

    A number of underground stores have been developed in recent years in Denmark. The development has been subsidised with funds of `Development program renewable energy` launched by the Danish Ministry for Environment and Energy. First experience reports on underground storage show that more emphasis must be put on the development of storage sealing and cover construction. Hence research works currently focuses on the investigation of liner material and further development of floating cover constructions. The target is the development of underground storage using solar energy for heating that can compete with conventional heating systems technically and economically. (orig.) [Deutsch] In Daenemark hat man in den letzten Jahren eine Reihe von Erdbeckenspeichern entwickelt.

Deshalb wird in Daenemark aktuell mit der Untersuchung von Linermaterialien und der Weiterentwicklung von schwimmenden Deckelkonstruktionen gearbeitet. Das Ziel dieser Arbeit ist es, Erdbeckenspeicher zu entwickeln, die die Ausnutzung von Sonnenenergie zur Waermeversorgung im Vergleich mit herkoemmlicher Waermeversorgung sowohl technisch als auch oekonomisch konkurrenzfaehig macht.

    In spite of the usual combination form of methotrexate (MTX)/mitoxantrone (MIT) and various complex combination regimens of MTX/MIT with other anticancer drugs, the survival period, cure rate, and systemic toxicity still need to be improved. For this purpose, a nanostructured amino group-modified mesoporous silica nanoparticles (MSNN)-MTX/MIT was designed. In the preparation, the surface of mesoporous silica nanoparticles (MSNs) was modified with amino groups to form MSNN. The covalent modification of the amino groups on the surface of MSNN with MTX resulted in MSNN-MTX. The loading of MIT into the surface pores of MSNN-MTX produced nanostructured MSNN-MTX/MIT. Compared with the usual combination form (MTX/MIT), nanostructured MSNN-MTX/MIT increased the survival period greatly, heightened the cure rate to a great extent, and lowered the systemic toxicity of the treated S180 mice, significantly. These superior in vivo properties of nanostructured MSNN-MTX/MIT over the usual combination form (MTX/MIT) were correlated with the former selectively releasing MTX and MIT in tumor tissue and inside cancer cells in vitro. The chemical structure and the nanostructure of MSNN-MTX/MIT were characterized using infrared and differential scanning calorimeter spectra as well as transmission electron microscope images, respectively.

    This paper describes, first, the international community of social scientists working on global change, and elaborates on possible contributions to this community by German political scientists. Second, the paper examines three new conceptual approaches to analysing global change, namely the Syndromes of Global Change approach, Earth System Analysis, and Sustainability Science. The paper then elaborates on a number of ways in which German political science could respond to the academic and political challenges posed by global change. It concludes by emphasizing the need for a new approach, focusing on 'world environmental policy analysis' that would bridge traditional (environmental) policy analysis, international relations research, and comparative politics.

  3. A review of the MIT experiments on the closed-loop digital control of reactor power

    International Nuclear Information System (INIS)

    Bernard, J.A.

    1989-01-01

    In this paper a review is provided of certain major experiments conducted from 1985 to 1988 as part of the MIT program on the development and demonstration of advanced technologies for the closed-loop digital control of nuclear reactors. Included are demonstrations of the supervisory control of neutronic power using an alternate formulation of the dynamic period equation, the use of the MIT-SNL Period-Generated Minimum Time Control Laws for the time-optimal control of neutronic power, and the evaluation of predictive displays as an operator aid. The significance of each of these advances is discussed in terms of the overall development of a multi-tiered controller that includes supervisory algorithms, predictive control laws, and automated reasoning

  4. Rethinking the Relationship Between Academia and Industry: Qualitative Case Studies of MIT and Stanford.

    2016-10-01

    As knowledge has become more closely tied to economic development, the interrelationship between academia and industry has become stronger. The result has been the emergence of what Slaughter and Leslie call academic capitalism. Inevitably, tensions between academia and industry arise; however, universities such as MIT and Stanford with long traditions of industry interaction have been able to achieve a balance between academic and market values. This paper describes the strategies adopted by MIT and Stanford to achieve this balance. The results indicate that implicit culture is a stronger determinant of balance than are explicit rules. Finally, the author proposes a concept of balance to reconsider the relationship between academia and industry: today's universities, particularly those with strengths in engineering and management, are both symbiotic and interdependent with industry. A reasonable attitude toward the university-industry relationship is that of balance rather than strict separation. Universities can thus establish effective mechanisms to reach a balance between conflicting values.

    The goal of the MIT mission is to understand the coupling of the magnetosphere and ionosphere from the prospective of particles. It will focus on the outflow of the ionosphere particles (mainly oxygen ions) from the Earth, including the acceleration mechanisms of oxygen ions and their relative importance in different regions, the importance of these ions while transferred into the magnetosphere and the roles they played in magnetosphere activities. A constellation of four satellites orbiting at three elliptical orbits will provide the unique opportunities to observed there ions at three different altitude with temporal changes of the flux of these particles and the magnetic field environments. The conceptual design of the spacecraft and a summary of the payload will be presented. The MIT mission was selected as one of the five candidates for the upcoming mission plan in China.

    MIT Hacking Medicine is a student, academic, and community-led organization that uses systems-oriented "healthcare hacking" to address challenges around innovation in healthcare. The group has organized more than 80 events around the world that attract participants with diverse backgrounds. These participants are trained to address clinical needs from the perspective of multiple stakeholders and emphasize utility and implementation viability of proposed solutions. We describe the MIT Hacking Medicine model as a potential method to integrate collaboration and training in rapid innovation techniques into academic medical centers. Built upon a systems approach to healthcare innovation, the time-compressed but expertly guided nature of the events could enable more widely accessible preliminary training in systems-level innovation methodology, as well as creating a structured opportunity for interdisciplinary congregation and collaboration.

    We calculate all twist-2, -3 and -4 parton distribution functions involving two quark correlations using the wave function of the MIT bag model. The distributions are evolved up to experimental scales and combined to give the various nucleon structure functions. Comparisons with recent experimental data on higher twist structure functions at moderate values of Q 2 give good agreement with the calculated structure functions. (orig.)

  12. Hardware for quasi-single-shot multifrequency magnetic induction tomography (MIT): the Graz Mk2 system

    International Nuclear Information System (INIS)

    Scharfetter, H; Köstinger, A; Issa, S

    2008-01-01

    Magnetic induction tomography (MIT) has been suggested by several groups for the contact-less mapping of the passive electrical properties of tissues via AC magnetic fields in the frequency range between several tens of kHz and several tens of MHz. Multifrequency MIT as an analog to multifrequency EIT has been tried and first image reconstructions have been demonstrated with phantoms. MIT appears to yield comparable images to EIT but offers the advantage of being non-contacting. In the beta-dispersion range of most tissues the method is challenging because the signals are very small and buried in noise. In order to minimize drifts and systematic errors fast data acquisition is therefore pivotal. This paper presents a method for single-shot MIT which allows us to acquire the data for a multifrequency image with an analog bandwidth of 50 kHz–1.5 MHz which covers a good part of the β-dispersion of many tissues. The transmit (TX) coils are simultaneously driven by individual power amplifiers with a multisinus pattern with up to 3 A pp . The amplifiers are configured as current sources so as not to perturb the excitation fields by inappropriately terminated coils. The separation of the different TX channels after reception is achieved by splitting up the carrier frequencies into individual subcarriers with a narrow spacing of at most 300 Hz. In this way every TX coil is identifiable by its own subcarrier but the whole excitation band is contained within a few kHz. The real and imaginary parts of the received signals are extracted efficiently with FFT. The system noise and the sources for low-frequency perturbations are analyzed and characterized

  14. Pionic corrections to the MIT bag model: The (3,3) resonance

    International Nuclear Information System (INIS)

    Theberge, S.; Thomas, A.W.; Miller, G.A.

    1980-01-01

    By incorporating chiral invariance in the MIT bag model, we are led to a theory in which the pion field is coupled to the confined quarks only at the bag surface. An equivalent quantized theory of nucleons and Δ's interacting with pions is then obtained. The pion-nucleon scattering amplitude in this model is found to give a good fit to experimental data on the (3,3) resonance, with a bag radius of about 0.72 fm

    The commonest method of thermal sewage sludge treatment at present is still combustion in mono-fluidised-bed plants. The possibilities described in the introduction of this paper give an impression of the great variety of disposal methods with a thermal final stage among which one can choose today. The solution that has been found to the disposal problems of four sewage plants in Berlin shows by way of example how a Europe-wide tender can lead to an inexpensive, permanent, secure, and flexible disposal system which includes recycling and figures as part of an integrated disposal system for different wastes. This disposal system has found ready acceptance on account of its environmental friendliness and sparing consumption of resources. Unlike incineration plants, its construction did not meet with public resistance. [Deutsch] Die zur Zeit noch haeufigste thermische Klaerschlammbehandlung ist die Verbrennung in Mono-Wirbelschichtanlagen. Die einleitend geschilderten Moeglichkeiten lassen jedoch die Vielfalt erkennen, die jetzt bei der Wahl eines Entsorgungsweges mit thermischer Endstufe gegeben sind. Die Loesung der Entsorgungsprobleme fuer 4 Berliner Klaerwerke hat beispielhaft gezeigt wie z.B. mittels eines europaweiten Ausschreibungsverfahrens ein kostenguenstiger, zeitlich nicht begrenzter, sicherer und flexibler Entsorgungsweg mit stofflicher Verwertung im Rahmen eines Verbundkonzeptes mit anderen Abfallstoffen gefunden werden kann. Ein Verwertungsweg, der allgemein wegen seiner Umweltvertraeglichkeit und Ressourcenschonung grosse Akzeptanz erfahren hat. Widerstand, wie beim Bau von Verbrennungsanlagen, hat es nicht gegeben.

    2016-01-01

    Hintergrund: Erkrankungen der Atemorgane treten mit steigendem Alter öfter auf, nehmen weltweit zu und sind häufige Ursachen für Morbidität und Mortalität. In dieser Pilotstudie wurde der Frage nachgegangen, ob eine einmalige 10-minütige Behandlung mit einer Körpertambura eine signifikante und effektive Verbesserung der Lungenfunktion von Patienten mit chronisch-obstruktiver Lungenerkrankung (COPD; GOLD-Stadium A oder B) erbringen kann. Patienten und Methoden: 54 Probanden konnten je zur Hälfte in eine Behandlungsgruppe (Körpertambura) und eine aktive Kontrollgruppe (Atemtherapie) randomisiert werden. Eine Bestimmung der Lungenfunktionsmessparameter «Einsekundenkapazität» (FEV1) und «inspiratorische Vitalkapazität» (IVC) zu den Zeitpunkten T1 (Baseline), T2 (direkt nach Behandlung) und als Follow-up etwa 3 Wochen nach T1 (T3). Ergebnisse: Die Behandlungsgruppe zeigte sich der Kontrollgruppe in beiden Werten signifikant überlegen. Die Zeit-×-Gruppe-Interaktion (Varianzanalyse) ergab p = 0,001 (FEV1) bzw. p = 0,04 (IVC). Die Behandlungsgruppe zeigte bei beiden Werten eine Verbesserung von klinischer Relevanz. Schlussfolgerung: Diese Ergebnisse zeigen, dass die Klangbehandlung mittels einer Körpertambura - neben den schulmedizinischen, leitliniengerechten Therapien - eine zusätzliche, nebenwirkungsarme, aber durchaus klinisch wirksame Option für die Behandlung von COPD-Patienten darstellen kann, um deren Lebensqualität zu stabilisieren und zu verbessern. © 2016 S.

    Mit mutations that disrupt function of the mitochondrial electron transport chain can, inexplicably, prolong Caenorhabditis elegans lifespan. In this study we use a metabolomics approach to identify an ensemble of mitochondrial-derived α-ketoacids and α-hydroxyacids that are produced by long-lived Mit mutants but not by other long-lived mutants or by short-lived mitochondrial mutants. We show that accumulation of these compounds is dependent on concerted inhibition of three α-ketoacid dehydrogenases that share dihydrolipoamide dehydrogenase (DLD) as a common subunit, a protein previously linked in humans with increased risk of Alzheimer's disease. When the expression of DLD in wild-type animals was reduced using RNA interference we observed an unprecedented effect on lifespan - as RNAi dosage was increased lifespan was significantly shortened, but, at higher doses, it was significantly lengthened, suggesting that DLD plays a unique role in modulating length of life. Our findings provide novel insight into the origin of the Mit phenotype. © 2012 The Authors Aging Cell © 2012 Blackwell Publishing Ltd/Anatomical Society of Great Britain and Ireland.

    To evaluate the accuracy of the Omron MIT Elite in pregnancy and pre-eclampsia according to the British Hypertension Society protocol (BHS). Prospective observational study. Antenatal clinics and wards at St. Thomas' Hospital (London, UK). Forty-five pregnant women including 15 with pre-eclampsia. Nine sequential same arm blood pressure (BP) measurements were taken from each woman by trained observers, alternating between mercury sphygmomanometry and the test device. Grading criteria of the BHS protocol (A/B grade=pass; C/D=fail). The Omron MIT Elite achieved a grade A/A in both pregnancy and pre-eclampsia. The mean difference (SD) between the mercury standard and the device in pregnancy was -1.1 (5.2)mmHg and 1.5 (4.8)mmHg for systolic and diastolic BP respectively compared to 0.2 (5.3)mmHg and 2.2 (5.5)mmHg in pre-eclampsia. The Omron MIT Elite can be recommended for use in pregnancy and pre-eclampsia according to the BHS protocol. To date, this is the most accurate automated BP device validated in pre-eclampsia.

    Hintergrund: In dieser Anwendungsbeobachtung wird zum ersten Mal die Behandlung des Reizdarmsyndroms (RDS) mit einem homöopathisch-phytotherapeutischen Komplexpräparat beschrieben. Methodik: Ziel der 6-wöchigen Therapie mit dem Magen-Darm-Entoxin N® war die Reduzierung der RDS-Symptomatik sowie die Verbesserung der Lebensqualität. Zielkriterien waren die Veränderungen in der Irritable Bowel Syndrome - Severity Scoring System (IBS-SSS) und der Irritable Bowel Syndrome - Quality-of-Life Scale (IBS-QoL). Die Patient/innen (N = 41; Alter 44,0 ± 15,74 Jahre) wurden zu gleichen Teilen in einer Hausarztpraxis (N = 20) und einer Heilpraktikerpraxis (N = 21) rekrutiert. Ergebnisse: Der IBS-QoL-Score verringerte sich signifikant (prä: 35,9 ± 16,3; post: 20,1 ± 13,4; t = 8,504; p mit einer Effektstärke von d = 1,24. Die Neben- und Wechselwirkungen waren minimal und signifikante Unterschiede zwischen beiden Praxen wurden nicht gefunden. Schlussfolgerungen: Magen-Darm-Entoxin N® ist eine sichere und sinnvolle Therapieoption bei der Behandlung des RDS. Allerdings sollten randomisierte kontrollierte Studien folgen, um die Spezifizität der Ergebnisse dieser Anwendungsbeobachtung zu stützen. © 2017 S. Karger GmbH, Freiburg.

    2011-11-01

    The MiT family comprises four genes in mammals: Mitf, Tfe3, Tfeb, and Tfec, which encode transcription factors of the basic-helix-loop-helix/leucine zipper class. Mitf is well-known for its essential role in the development of melanocytes, however the functions of the other members of this family, and of interactions between them, are less well understood. We have now characterized the complete set of MiT genes from zebrafish, which totals six instead of four. The zebrafish genome contain two mitf (mitfa and mitfb), two tfe3 (tfe3a and tfe3b), and single tfeb and tfec genes; this distribution is shared with other teleosts. We present here the sequence and embryonic expression patterns for the zebrafish tfe3b, tfeb, and tfec genes, and identify a new isoform of tfe3a. These findings will assist in elucidating the roles of the MiT gene family over the course of vertebrate evolution. Copyright © 2011 Wiley-Liss, Inc.

    In Hadronproduktionsdaten der e+e− - Vernichtungsexperimente JADE und OPAL messen wir die ersten f¨unf Momente von zw¨olf hadronischen Ereignisformvariablen bei Schwerpunktsenergien von 14 bis 207GeV. Aus dem Vergleich der QCD NLO-Vorhersage mit den mittels MC-Modellen um Hadronisierung korrigierten Daten erhalten wir den Referenzwert der starken Kopplung αs(MZ0) = 0.1254 ± 0.0007(stat.) ± 0.0010(exp.)+0.0009 −0.0023(had.)+0.0069 −0.0053(theo.) . F¨ur einige, insbesondere h¨ohere, Momente sind systematische Unzul¨anglichkeiten in der QCD NLO-Vorhersage erkenntlich. Simultane Fits an zwei Momente unter Annahme identischer Renormierungsskalen ergeben Skalenwerte von xμ=0.057 bis xμ=0.196 . Wir pr¨ufen Vorhersagen verschiedener nichtperturbativer Modelle. Aus der Single Dressed Gluon - N¨aherung ergibt sich eine perturbative Vorhersage in O(α5 s ) mit zu vernachl¨assigender Energiepotenzkorrektur, die den Mittelwert von Thrust auf Hadronniveau gut beschreibt mit αs(MZ0) = 0.1186 ± 0.0007(st...

    Nickel, Felix; Wegner, Ingmar; Kenngott, Hannes; Neuhaus, Jochen; Müller-Stich, Beat P.; Meinzer, Hans-Peter; Gutt, Carsten N.

    In dieser Studie wurde untersucht ob in einem typischen OP-Aufbau mit dem da Vinci® Telemanipulator elektromagnetisches Tracking für die Realisation eines Navigationssystems eingesetzt werden kann. Hierfür wurde in einem realen OP-Aufbau untersucht, wie stark metallische und ferromagnetisch wirksame Objekte wie Operationstisch und Telemanipulator das elektromagnetische Feld des Trackingsystems beeinflussen. Die Ergebnisse zeigen, dass der Telemanipulator nur unwesentlich die Störung des Magnetfeldes durch den OP-Tisch verstärkt. Insbesondere die Bewegung der Instrumente im Trackingvolumen verursachte keine zusätzliche relevante Störung des Magnetfeldes. Bei Begrenzung des Trackingvolumens auf eine Länge von 190 mm, Höhe von 200mm und Breite von 400 mm war der maximale Fehler in diesem Bereich an allen Messpunkten kleiner 10 mm. Der Einsatz von elektromagnetischem Tracking für die Navigation mit dem da Vinci® Surgical System ist somit in einem begrenzten Arbeitsvolumen mit hinreichender Genauigkeit möglich.

A large range of operation at a constant height of fall is ensured by a variable revolution number. The profiles of the adjustable diffusor and rotor disk and the design of the draft tube were optimized using numerical flow calculation. First operating experience is very positive. The turbine runs extremely smoothly over the entire range. (orig.) [Deutsch] Das Kleinwasserkraftwerk Rupboden in Oberfanken wurde nach 30 Jahren Stillstand reaktiviert. Die neue Niederdruckanlage besteht aus einer Schachtturbine mit verstellbarem Leitapparat, feststehendem Laufrad (Propeller) mit senkrechter Welle. Zum Erzielen eines grossen Betriebsbereiches bei gleichbleibender Fallhoehe wurde eine variable Drehzahl vorgesehen. Die Profilierung von Leitapparat und Laufrad sowie die Formgebung fuer das Saugrohr wurden mit numerischer Stroemungsberechnung optimiert. Erste Betriebserfahrungen sind sehr positiv. Die Turbine laeuft im gesamten Leistungsbereich ausserordentlich ruhig. (orig.)

    Within the framework of a project sponsored by the Stiftung Energieforschung Baden-Wuerttemberg, an axial turbine was developed as a flash evaporator, which permits energy recovery in all sectors where liquids in piping undergoes pressure relaxation. A specific feature of this turbine is that it forms part, complete with generator, of a single pipeline and that it does not cause any pressure variations worth mentioning in case of mains failure. The report describes the turbine, its advantages, and a pilot operation carried out with a prototype. The turbine`s performance is compared with a return pump. Further, the optimization of the hydraulic design by computer and the results of a market analysis are dealt with. (orig.) [Deutsch] Im Rahmen einer von der Stiftung Energieforschung Baden-Wuerttemberg gefoerderten Neuentwicklung wurde eine Axialturbine als Entspannungsturbine entwickelt, mit der eine Energierueckgewinnung in allen Bereichen erfolgen kann, in denen Fluessigkeiten in Rohrleitungssystemen entspannt werden. Die Turbine zeichnet sich unter anderem dadurch aus, dass sie komplett, inklusive Generator, innerhalb einer Rohrleitung angeordnet ist und bei Netzausfall keine nennenswerte Druckschwankung erzeugt. Es werden die Turbine, deren Vorteile sowie der mit einem Prototypen durchgefuehrte Betriebsversuch beschrieben. Weiterhin werden ein Vergleich des Betriebsverhaltens mit einer rueckwaertslaufenden Pumpe, die rechnerische Optimierung der hydraulischen Formgebung sowie die Ergebnisse einer Marktanalyse behandelt.

    The first natural gas vehicles form BMW are designed for arbitrary gasoline or natural gas operation. It is possible only to a limited extent to take advantage of the benefits of natural gas as a fuel as long as this is the case. An analysis was made to determine possible improvements in terms of fuel economy, emissions, full load and maximum exhaust gas temperatures through selective optimisation for exclusive natural gas operation. The results of this analysis have been used in the design of natural gas engines for mid-sized vehicles. Vehicle examinations in FTP75 confirm the existing potential for satisfying EZEV standards discussed in California even with vehicles of the upper midsize category by using optimised natural gas engines. (orig.) [Deutsch] Die ersten Automobile mit Erdgasantrieb von BMW sind fuer den wahlweisen Benzin- oder Erdgasbetrieb ausgelegt. Deshalb koennen die Vorteile des Kraftstoffs Erdgas nur zum Teil genutzt werden. Es wurde untersucht, welche Verbesserungen durch gezielte Optimierung fuer den ausschliesslichen Erdgasbetrieb bei Kraftstoffverbrauch, Emissionen, Vollast und maximalen Abgastemperaturen moeglich sind. Die Ergebnisse wurden bei der Auslegung von Erdgasmotoren fuer Mittelklassefahrzeuge verwendet. Untersuchungen im FTP-75 bestaetigen, dass mit optimierten Erdgasmotoren das Potential besteht, selbst mit Automobilen der oberen Mittelklasse die in Kalifornien diskutierten EZEV-Standards zu erfuellen.

    The critical role of chitin synthases in oomycete hyphal tip growth has been established. A microtubule interacting and trafficking (MIT) domain was discovered in the chitin synthases of the oomycete model organism, Saprolegnia monoica. MIT domains have been identified in diverse proteins and may play a role in intracellular trafficking. The structure of the Saprolegnia monoica chitin synthase 1 (SmChs1) MIT domain has been recently determined by our group. However, although our in vitro assay identified increased strength in interactions between the MIT domain and phosphatidic acid (PA) relative to other phospholipids including phosphatidylcholine (PC), the mechanism used by the MIT domain remains unknown. In this work, the adsorption behavior of the SmChs1 MIT domain on POPA and POPC membranes was systematically investigated by molecular dynamics simulations. Our results indicate that the MIT domain can adsorb onto the tested membranes in varying orientations. Interestingly, due to the specific interactions between MIT residues and lipid molecules, the binding affinity to the POPA membrane is much higher than that to the POPC membrane. A binding hotspot, which is critical for the adsorption of the MIT domain onto the POPA membrane, was also identified. The lower binding affinity to the POPC membrane can be attributed to the self-saturated membrane surface, which is unfavorable for hydrogen-bond and electrostatic interactions. The present study provides insight into the adsorption profile of SmChs1 and additionally has the potential to improve our understanding of other proteins containing MIT domains.

Patienten und Methoden: Von 01/97 bis 09/99 behandelten wir 102 Patienten mit Prostatakarzinomen im Stadium T1–3 N0 M0. Im Stadium T1–2 befanden sich 71, im Stadium T3 31 Patienten. Der mediane prätherapeutische PSA-Wert betrug 15,3 ng/ml. Nach ultraschallgesteuerter transrektaler Implantation von vier Afterloadingnadeln erfolgte die CT-gestützte 3D-Brachytherapie- Planung. Alle Patienten erhielten vier HDR-Implantate mit einer Referenzdosis von 5 Gy oder 7 Gy pro Implantat. Die Zeit zwischen jedem Implantat betrug jeweils 14 Tage. Nach der Brachytherapie folgte die externe Radiotherapie bis 39,6 Gy oder 45,0 Gy. Alle Patienten erhielten eine neoadjuvante und adjuvante Kurzzeit-Hormontherapie, die 2–19 Monate vor der Brachytherapie eingeleitet und 3 Monate nach Abschluß der externen Radiotherapie abgesetzt wurde (mediane Dauer: 9 Monate. Ergebnisse: Die mediane Nachbeobachtungszeit war 2,6 Jahre (range: 2,0–4,1 Jahre. Die biochemische Kontrollrate betrug 82 % nach 3 Jahren. Bei 14/102 Patienten registrierten wir ein biochemisches Rezidiv, bei 5/102 Patienten ein klinisches Rezidiv. Das Gesamtüberleben betrug 90 %, das krankheitsspezifische Überleben 98,0 % nach 3 Jahren. Ein Patient entwickelte eine prostato-urethro-rektale Fistel als späte Grad 4-Toxizität. Akute Grad-3 Toxizitäten traten bei 4 %, späte Grad-3 Toxizitäten bei 5 % der Patienten auf. Schlußfolgerung: Die neoadjuvante und adjuvante Kurzzeit-Hormontherapie kombiniert mit konformaler HDR-Brachytherapie und externer Radiotherapie erweist sich als sichere und wirksame Behandlungsmodalität beim Prostatakarzinom mit minimalen behandlungsbedingten Toxizitäten und einer vielversprechenden biochemischen Kontrollrate nach medianer Nachbeobachtungszeit von 2,6 Jahren.

    Purpose: To differentiate between urodynamically relevant obstruction and functionally unimportant dilation of the upper urinary tract in patients with neobladder using a modified furosemide urogram. Method: An excretory urogram with furosemide loading was carried out in 19 patients with neobladder and sonographically and urographically confirmed dilation of the upper urinary tract. Once strong contrasting of the renal pelves and calyces has been achieved, 20 mg of furosemide were applied and late radiographs were obtained at 15 min and 30 min, respectively. An obstruction was defined as increasing dilation of the renal pelves and calices during forced diuresis and lack of washout effect of the contrast medium. Results: In 32 cases, the renoureteral unit (RUU) was dilated on ultrasound. Of these, 25 RUU`s showed good emptyness of contrast medium upon stimulation of diuresis, six RUU`s returned a borderline findings, while one RUU was found to exhibit a decompensated anastomotic stenosis, which was dilated. Two further patients with bordeline findings were later treated surgically due to their pain symptoms. No patient required further preoperative diagnostic procedures. Conclusions: The modified furosemide urogram represents a cost-effective diagnostic orientation strategy in patients with neobladder and dilated renal pelves and calyses and is both well-tolerated by patients and meets with broad acceptance from the urologic staff.

    1999-01-01

    For many decades, Dr. Claus Berke worked at the interface of technology and politics. This is particularly true of nuclear technology. Between 1985 and 1989, he was Chairman of the Kerntechnische Gesellschaft; between 1989 and 1995, President of the Deutsches Atomforum. In Brussels, he was President of Foratom for a period of two years. Dr. Berke has been distinguished by a number of awards for his services. The Kerntechnische Gesellschaft has now appointed him its Honorary Member in recognition of his commitment to nuclear technology. The article is an excerpt from a speech made by Dr. Berke to the KTG at the awarding ceremony. Dr. Berke deals with the question why the acceptance of nuclear power in this country has become so negative, in contrast to the situation with our main competitors on the world market, especially France. He traces the growth of ideologies in the German political party scene, which resulted in destroying national unity in this important issue for the future. He feels that one of the major reasons for this development lies in the considerable loss of reputation and influence in the German public of science and engineering over the past thirty years. The situation with our French neighbors is quite different. Already French schools attach particular importance to mathematics, biology, physics, and chemistry. As a consequence, technical and scientific curricula are very attractive in France, while Germany is heading toward the paradoxical situation that industry will soon be short of more than ten thousand young engineers annually, while German universities produce a surplus of humanists for whom there will often be no proper jobs.

    This paper aims to estimate the prevalence of cigarette smoking among students in Vietnam ages 13-15 and examines its relationship with compositional and contextual factors. The data used in this paper were obtained from the 2007 Global Youth Tobacco Survey conducted in nine provinces in Vietnam. A multilevel logistic regression model was applied to analyse the association between the current incidence of cigarette smoking and factors on both the individual and school level. The prevalence of cigarette smoking among students was 3.3% overall. The prevalence of smoking among male students (5.9%) was higher than that among females (1.2%). Parental smoking was a significant risk factor for smoking among the students. Having a friend who smoked was the strongest predictor of smoking status among the study subjects. We have demonstrated that school-level factors appeared to impact the prevalence of cigarette smoking among students ages 13-15. This paper highlights the importance of utilising an extensive range of actions to prevent students from using tobacco in Vietnam. These actions should include providing specific curricula for students that address both individual characteristics and the school environment. Further, prevention programmes should also target both parental- and peer-smoking issues.

    The Harvard-MIT Program in Health Sciences and Technology (HST) is a flexible, preclinical curriculum, taught by members of the faculties of both Harvard University and the Massachusetts Institute of Technology, that stresses a rigorous, scientific, quantitative approach, small classes (usually fewer than 50 students), and student-faculty interaction. The program is aimed at students with strong backgrounds in quantitative and biological sciences who are interested in careers as physician-scientists. The first 234 students of the program, who graduated between 1975 and 1985, were asked to participate in a 1990 follow-up study by completing a four-page questionnaire and submitting curricula vitae and lists of publications, if available. Data were analyzed quantitatively and qualitatively. Of the 234 graduates, 211 (90%) responded. Sixty-three (30%) had received both MD and PhD degrees. The graduates were twice as likely to describe their primary professional roles as academic than as clinical practice; 94 held full-time faculty positions at 50 medical schools. The 154 (73%) in research spent an average of 51% of their time on this activity. According to the 179 graduates (85%) who stated that they would choose HST again, the most frequently mentioned reasons were the quantitative approach that emphasized integration of basic science and clinical practice (49%) and the small class size (37%). The HST MD curriculum, with its emphasis on basic science and research experience, has been successful in preparing carefully selected students for careers as physician-scientists, without necessarily requiring the completion of a PhD degree.

  14. MitProNet: A knowledgebase and analysis platform of proteome, interactome and diseases for mammalian mitochondria.

    Jiabin Wang

    Full Text Available Mitochondrion plays a central role in diverse biological processes in most eukaryotes, and its dysfunctions are critically involved in a large number of diseases and the aging process. A systematic identification of mitochondrial proteomes and characterization of functional linkages among mitochondrial proteins are fundamental in understanding the mechanisms underlying biological functions and human diseases associated with mitochondria. Here we present a database MitProNet which provides a comprehensive knowledgebase for mitochondrial proteome, interactome and human diseases. First an inventory of mammalian mitochondrial proteins was compiled by widely collecting proteomic datasets, and the proteins were classified by machine learning to achieve a high-confidence list of mitochondrial proteins. The current version of MitProNet covers 1124 high-confidence proteins, and the remainders were further classified as middle- or low-confidence. An organelle-specific network of functional linkages among mitochondrial proteins was then generated by integrating genomic features encoded by a wide range of datasets including genomic context, gene expression profiles, protein-protein interactions, functional similarity and metabolic pathways. The functional-linkage network should be a valuable resource for the study of biological functions of mitochondrial proteins and human mitochondrial diseases. Furthermore, we utilized the network to predict candidate genes for mitochondrial diseases using prioritization algorithms. All proteins, functional linkages and disease candidate genes in MitProNet were annotated according to the information collected from their original sources including GO, GEO, OMIM, KEGG, MIPS, HPRD and so on. MitProNet features a user-friendly graphic visualization interface to present functional analysis of linkage networks. As an up-to-date database and analysis platform, MitProNet should be particularly helpful in comprehensive studies of

    Global health rotations are increasingly popular amongst medical students. The training abroad is highly variable and there is a recognized need for global health curriculum development. We sought to create and evaluate a curriculum, applicable to any global health rotation, that requires students to take an active role in their education and promotes engagement. Prospective, observational, mixed method study of 4th year medical students enrolled in global health courses at UCLA in 2011-12. Course directors identified 4 topics common to all rotations (traditional medicine, health systems, limited resources, pathology) and developed activities for students to complete abroad: observation, interview and reflection on resources, pathology, medical practices; and compare/contrast their experience with the US healthcare system. Students posted responses on a discussion board moderated by US faculty. After the rotation, students completed an anonymous internet-based evaluative survey. Responses were tabulated. Qualitative data from discussion board postings and free response survey items were analyzed using the framework method. 14 (100 %) students completed the Activated Learning assignment. 12 submitted the post rotation survey (85.7 %). Activated Learning enhanced GH education for 67 % and facilitated engagement in the local medical culture for 67 %. Qualitative analysis of discussion board posting demonstrated multiple areas of knowledge gain and analysis of free response survey items revealed 5 major themes supporting Activated Learning: guided learning, stimulation of discussion, shared interactions, cultural understanding, and knowledge of global healthcare systems. Increased interactivity emerged as the major theme for future improvement. The results of this study suggest that an Activated Learning program may enhance education, standardize curricular objectives across multiple sites and promote engagement in local medical culture, pathology and delivery

    The endosomal sorting complexes required for transport (ESCRT) pathway drives reverse topology membrane fission events within multiple cellular pathways, including cytokinesis, multivesicular body biogenesis, repair of the plasma membrane, nuclear membrane vesicle formation, and HIV budding. The AAA ATPase Vps4 is recruited to membrane necks shortly before fission, where it catalyzes disassembly of the ESCRT-III lattice. The N-terminal Vps4 microtubule-interacting and trafficking (MIT) domains initially bind the C-terminal MIT-interacting motifs (MIMs) of ESCRT-III subunits, but it is unclear how the enzyme then remodels these substrates in response to ATP hydrolysis. Here, we report quantitative binding studies that demonstrate that residues from helix 5 of the Vps2p subunit of ESCRT-III bind to the central pore of an asymmetric Vps4p hexamer in a manner that is dependent upon the presence of flexible nucleotide analogs that can mimic multiple states in the ATP hydrolysis cycle. We also find that substrate engagement is autoinhibited by the Vps4p MIT domain and that this inhibition is relieved by binding of either Type 1 or Type 2 MIM elements, which bind the Vps4p MIT domain through different interfaces. These observations support the model that Vps4 substrates are initially recruited by an MIM-MIT interaction that activates the Vps4 central pore to engage substrates and generate force, thereby triggering ESCRT-III disassembly. © 2015 by The American Society for Biochemistry and Molecular Biology, Inc.

Here, we report quantitative binding studies that demonstrate that residues from helix 5 of the Vps2p subunit of ESCRT-III bind to the central pore of an asymmetric Vps4p hexamer in a manner that is dependent upon the presence of flexible nucleotide analogs that can mimic multiple states in the ATP hydrolysis cycle. We also find that substrate engagement is autoinhibited by the Vps4p MIT domain and that this inhibition is relieved by binding of either Type 1 or Type 2 MIM elements, which bind the Vps4p MIT domain through different interfaces. These observations support the model that Vps4 substrates are initially recruited by an MIM-MIT interaction that activates the Vps4 central pore to engage substrates and generate force, thereby triggering ESCRT-III disassembly.

    The concept of usability has become an increasingly important consideration in the design of all kinds of technology. As more products are aimed at global markets and developed through internationally distributed teams, usability design needs to be addressed in global terms. Interest in usability as a design issue and specialist area of research and education has developed steadily in North America and Europe since the 1980's. However, it is only over the last ten years that it has emerged as a global concern. Global Usability provides an introduction to the important issues in globalizing des

    Scientific warnings of world-wide climate changes through human activities were voiced even as long ago as 100 years before now. A chain of evidence reaching into our time has since turned up. With the first UN world climate conference in 1979, climate change became a concern of climatologists all over the world. Many scientists fear that man has already triggered global warming by emissions of trace gases into the atmosphere. (orig.)

    2014-09-01

    Tom G. K. Bryce and Stephen P. Day's (2013) original article on scepticism and doubt in science education explores the context of citizens' attitudes towards the complexities and uncertainties of global issues, namely global warming. This response aims to stimulate reflection on some of the implicit assumptions underpinning the relationships between science, technology and the public. I argue that an underestimation of the political and ethical dimensions of science and technology limits the possibilities for education to set the agenda for citizens' participation in science and technological matters. Drawing on Sheila Jasanoff's model of co-production, this paper proposes a radical re-affirmation of the aims and purposes of science education to embrace a multiplicity of disciplines, narratives and ways of knowing in science, technology and society issues.

    Young adults with personality disorders (PD) other than borderline are in urgent need of validated treatments to help them in managing important life transitions. Therapeutic interventions focused upon social and interpersonal difficulties may facilitate these individuals in maximizing opportunities for employment, forming stable romantic relationships, and belong to social groups. It is also important that they are offered evidence-based, first-line time-limited treatments in order to maximize effectiveness and reduce costs. We developed a 16-session programme of group-based Metacognitive Interpersonal Therapy (MIT-G) including psychoeducation on the main interpersonal motives, an experiential component enabling practice of awareness of mental states; and use of mentalistic knowledge for purposeful problem-solving. We report a feasibility, acceptability, and clinical significance randomized clinical trial. Participants meeting inclusion criteria were randomized to receive MIT-G (n = 10) or waiting list+TAU (n = 10). Dropout rate was low and session attendance high (92.19%). Participants in the MIT-G arm had symptomatic and functional improvements consistent with large effect sizes. In the MIT-G arm similarly large effects were noted for increased capacity to understand mental states and regulate social interactions using mentalistic knowledge. Results were sustained at follow-up. Our findings suggest potential for applying MIT-G in larger samples to further test its effectiveness in reducing PD-related symptoms and problematic social functioning. © 2018 The British Psychological Society.

  10. Eddy current testing with high penetration; WS-Pruefungen mit grosser Eindringtiefe

    The low-frequency eddy current testing method is used when penetration into very deep layers is required. The achievable penetration depth is determined among other parameters by the lowest testing frequency that can be realised together with the eddy current sensor. When using inductive sensors, the measuring effect declines proportional to the lowering frequency (induction effect). Further reduction of testing frequency requires other types of sensors, as e.g. the GMR (Giant Magnetic Resistance), which achieves a constant measuring sensitivity down to the steady field. The multi-frequency eddy current testing method MFEC 3 of IZFP described here can be operated using three different scanning frequencies at a time. Two variants of eddy current probes are used in this case. Both have an inductive winding at their emitters, of the type of a measuring probe. The receiver end is either also an inductive winding, or a magnetic field-responsive resistance (GMR). (orig./CB) [Deutsch] Das Niederfrequenz(NF)-Wirbelstrom(WS)-Verfahren wird eingesetzt, um eine grosse Eindringtiefe zu erzielen. Die erreichbare Tiefenreichweite wird u.a. durch die niedrigste Prueffrequenz bestimmt, die zusammen mit dem Wirbelstrom-Sensor realisiert werden kann. Bei Einsatz von induktiven Sensoren geht mit abnehmender Prueffrequenz der Messeffekt proportional zurueck (Induktionswirkung). Eine weitere Absenkung der Prueffrequenzen macht den Einsatz von andersartigen Sensoren notwendig, z.B. den GMR (Giant Magnetic Resistance), der eine gleichmaessige Messempfindlichkeit bis zum Gleichfeld besitzt. Das eingesetzte Mehrfrequenz-Wirbelstrom-Pruefverfahren MFEC 3 des IZFP arbeitet mit drei gleichzeitig eingespeisten Prueffrequenzen. Dabei werden zwei Varianten von WS-Sensoren eingesetzt. Beide besitzen auf der Senderseite eine induktive Wicklung in der Art einer Tastsonde. Die Empfaengerseite ist entweder ebenfalls eine induktive Wicklung oder ein magnetfeldempfindlicher Widerstand (GMR). (orig./DGE)

    Nature is providing a once-per-thousand year opportunity to study the geophysical outcome induced on an unprecedentedly large (350 meter) asteroid making an extremely close passage by the Earth (inside the distance of geosynchronous satellites) on Friday April 13, 2029. The aircraft carrier-sized (estimated 20 million metric ton) asteroid is named Apophis. While many previous spacecraft missions have studied asteroids, none has ever had the opportunity to study "live" the outcome of planetary tidal forces on their shapes, spin states, surface geology, and internal structure. Beyond the science interest directly observing this planetary process, the Apophis encounter provides an invaluable opportunity to gain knowledge for any eventuality of a known asteroid found to be on a certain impact trajectory. MIT's Project Apophis [1] is our response to nature's generous opportunity by developing a detailed mission concept for sending a spacecraft to orbit Apophis with the objectives of surveying its surface and interior structure before, during, and after its 2029 near-Earth encounter. The Surface Evaluation & Tomography (SET) mission concept we present is designed toward accomplishing three key science objectives: (1) bulk physical characterization, (2) internal structure, and (3) long-term orbit tracking. For its first mission objective, SET will study Apophis' bulk properties, including: shape, size, mass, volume, bulk density, surface geology, and composition, rotation rate, and spin state. The second mission objective is to characterize Apophis' internal structure before and after the encounter to determine its strength and cohesion - including tidally induced changes. Finally, the third objective studies the process of thermal re-radiation and consequential Yarkovsky drift, whose results will improve orbit predictions for Apophis as well as other potentially hazardous asteroids.

  12. Expanding educational access and opportunities: The globalization and foreign direct investment of multinational corporations and their influence on STEM, project-based learning and the national science and technology fair in schools in Costa Rica

    Science.gov (United States)

    Valdez, Joaquin G.

    The purpose of this qualitative study was to examine the influence of globalization and the foreign direct investment (FDI) of multinational corporations (MNCs) on the curriculum in schools in Costa Rica. The study focused primarily on Science, Technology, Engineering and Mathematics (STEM), Project-Based Learning (PBL), 21st century skills, and the national science and technology fair. The high influx of MNCs such as Intel has changed the global and educational culture of the country increasing the number of knowledge-based workers in Costa Rica. As a result, policy changes have been instituted in education to mirror the demands of sustaining the country's global economy. This study was supported by the creation of three research questions that would attempt to answer 1) the extent that teachers implementing STEM curriculum trace their practices back to policy, globalization, and multinational corporations as well as the extent to which the economic growth of Costa Rica and STEM education are related, 2) how mandating the national science and technology fair has influenced 21st century skills through project-based learning and the use of technology by teachers and its impact on curriculum and instruction, and 3) how has the national science and technology fair policy changed the value of STEM education for students, teachers, and educational leaders. To further understand the outcome of this study, four theoretical frameworks were applied that included, Spring's theory of world educational culture, Friedman's world flatteners, Wagner's 21st century skills and partnerships for 21st century skills, and Slough and Milam's STEM project-based learning theoretical framework. Each framework was applied to support the changes to the educational system; survival skills necessary to compete in the global job market; application of 21st century skills in the classroom and in the science projects students created.

  14. How global brands compete.

    Science.gov (United States)

    Holt, Douglas B; Quelch, John A; Taylor, Earl L

    2004-09-01

    It's time to rethink global branding. More than two decades ago, Harvard Business School professor Theodore Levitt argued that corporations should grow by selling standardized products all over the world. But consumers in most countries had trouble relating to generic products, so executives instead strove for global scale on backstage activities such as production while customizing product features and selling techniques to local tastes. Such "glocal" strategies now rule marketing. Global branding has lost more luster recently because transnational companies have been under siege, with brands like Coca-Cola and Nike becoming lightning rods for antiglobalization protests. The instinctive reaction of most transnational companies has been to try to fly below the radar. But global brands can't escape notice. In fact, most transnational corporations don't realize that because of their power and pervasiveness, people view them differently than they do other firms. In a research project involving 3,300 consumers in 41 countries, the authors found that most people choose one global brand over another because of differences in the brands'global qualities. Ratherthan ignore the global characteristics of their brands, firms must learn to manage those characteristics. That's critical, because future growth for most companies will likely come from foreign markets. Consumers base preferences on three dimensions of global brands--quality (signaled by a company's global stature); the cultural myths that brands author; and firms' efforts to address social problems. The authors also found that it didn't matter to consumers whether the brands they bought were American--a remarkable finding considering that the study was conducted when anti-American sentiment in many nations was on the rise.

    Rother, Claudia; Schnelle, Martin

    Hintergrund: Schlafstörungen gehören zu den häufigsten gesundheitlichen Problemen der heutigen Zeit. Stress und die dadurch bedingte innere Anspannung sowie eine unrhythmische Lebensführung z.B. durch Schichtarbeit sind bekannte auslösende Faktoren. Weniger bekannt ist, dass auch funktionelle Herz-Kreislauf-Beschwerden zu Störungen des Schlafs führen können und dass deren Behandlung zu einer Verbesserung der Schlafqualität beiträgt. Ganzheitlich betrachtet geht es daher um die Wiederherstellung einer gesunden Rhythmik, insbesondere des Herz-/Atem- sowie des Schlaf-Wach-Rhythmus, die Cardiodoron®, eine Heilpflanzenkomposition aus Primula veris, Hyoscyamus niger und Onopordum acanthium, unterstützt. Patienten und Methoden: Mittels einer prospektiven, multizentrischen Beobachtungsstudie sollte ermittelt werden, wie sich funktionelle Herz-Kreislauf-Beschwerden und/oder Schlafstörungen unter der Behandlung mit Cardiodoron® (Dilution) über 3-6 Monate entwickeln. Im Zeitraum von September 2009 bis März 2012 dokumentierten 92 Ärzte 501 Patienten, von denen 380 über Schlafstörungen klagten und deren Daten in dieser Publikation näher betrachtet werden. Nach einer Aufnahmeuntersuchung erfolgte nach 90 Tagen eine Abschlussuntersuchung und bei Fortführung der Therapie nach nochmals 90 Tagen eine Follow-up-Untersuchung. Neben 30 ärztlicherseits bewerteten Symptomen beurteilten die Patienten ihr Befinden mittels Pittsburgh Sleep Quality Index (PSQI) nach Buysse und der Beschwerden-Liste nach von Zerssen (B-L und B-L'). Ergebnisse: Unter der Cardiodoron®-Therapie gingen bei guter Verträglichkeit sowohl die Ausprägung der Schlafstörungen (um 65% von 2,0 auf 0,7 Punkte) als auch die erfassten 30 Symptome (um 59% von 24,3 auf 9,9 Punkte) deutlich zurück (p mit Schlafstörungen (mit oder ohne funktionelle Herz-Kreislauf-Beschwerden) kann die Ausprägung der Beschwerden mit Cardiodoron® deutlich gesenkt werden.

    In this paper the energy densities of the vacuum in the Wigner and the Goldstone modes of the Nambu- Jona-Lasinio Hamiltonian are calculated. The difference of these two quantities is analogous to the condensation energy of a BCS superconductor, and is used here to estimate the temperature dependence of the MIT bag constant. The formalism of da Providencia et al is generalized to finite temperatures, yielding the same gap equation as the finite- temperature field theory. The thermodynamics of the vacuum in the two phases is studied

    In California there are already 350 MW{sub e} worth of solar thermal energy plants in operation on a more or less commercial basis. In these installations thermal oil in parabolic gutters is heated from 300 C to 400 C. The thermal oil passes its thermal energy on to a water vapour circuit via a heat exchanger. The water vapour circuit can also be heated with natural gas, for instance at night when solar energy is not available. However, as yet no existing plant fulfils all three of the following requirements: its construction should entail the lowest possible investment costs and it should be able to run without solar energy and without an expensive storage system; it should have the greatest possible efficiency, especially at times when solar energy is not available (e.g. at night); at the same time, the solar thermal energy should be harvested at the lowest possible temperature so as to make expensive concentrating equipment superfluous. These seemingly contradictory demands are now met by a new concept involving a combined gas and steam plant whose operation is based on the injection of water into the compressed air rather than on a high excess of air. This water is evaporated by solar thermal energy at temperatures below 170 C according to its partial pressure. [Deutsch] Es gibt bereits ueber 350 MWe solarthermische Anlagen in Kalifornien, die mehr oder weniger kommerziell betrieben werden.

In einem weiteren Schritt wurde vorgeschlagen, das Wasser direkt zu verdampfen. Keine dieser Anlagen genuegt jedoch gleichzeitig den folgenden drei Anforderungen: Die Anlage sollte mit moeglichst niedrigen Investitionskosten gebaut und auch ohne Solarwaerme bzw. ohne aufwendigen Speicher betrieben werden koennen

    The MIT extraction method for obtaining flow split data for individual subchannels is described in detail. An analysis of the method is presented which shows that isokinetic values of the subchannel flow rates are obtained directly even though the method is non-isokinetic. Time saving methods are discussed for obtaining the average value of the interior region flow split parameter. An analysis of the method at low bundle flow rates indicates that there is no inherent low flow rate limitation on the method and suggests a way to obtain laminar flow split data

    The material is summarized that was covered by the MIT/NASA Waterville Valley workshop which dealt with the institutional, socio-economic, operational and technological problems associated with introducing new forms of short haul domestic air transportation. It was found that future air systems hold great potential in satisfying society's needs for a low noise, low landspace, high access, high speed, large network system for public travel over distances between 5 and 500 miles. It is concluded that quiet air systems are necessary for obtaining community approval, and is recommended that extremely high priority be assigned to the development of quiet aircraft for future short haul air systems.

Ziel dieser Studie ist, sowohl das klinische Ansprechen und die unerwünschten Nebenwirkungen als auch die Patientenwahrnehmung hinsichtlich intraläsionaler Injektionen von anti-CD20-Antikörpern zur Behandlung indolenter primär kutaner B-Zell-Lymphome im Vergleich mit anderen Therapien zu evaluieren. Elf Patienten mit einem primär kutanen B-Zell-Lymphom, namentlich primär kutanes Keimzentrumslymphom (n = 9) und primär kutanes Marginalzonenlymphom (n = 2), welche mittels intraläsionalem Anti-CD20-Antikörper behandelt wurden, wurden retrospektiv evaluiert hinsichtlich der Ansprechrate und unerwünschter Nebenwirkungen sowie in Bezug auf deren Selbsteinschätzung dieser und anderer Therapien des primär kutanen B-Zell-Lymphoms. Patienten, deren primär kutanes B-Zell-Lymphom mittels intraläsionaler Gabe von Anti-CD20-Antikörper behandelt wurde, zeigten ein komplettes oder partielles Ansprechen in 45 % beziehungsweise 27 % aller Patienten. Speziell Patienten mit grippeähnlichen Symptomen nach erfolgter Injektion zeigten ein gutes Ansprechen. Die Mehrheit der Patienten empfand die Therapie mit Rituximab als die beste Therapie im Vergleich zu anderen Therapien wie beispielsweise chirurgische Exzision oder Radiotherapie. Intraläsionales Rituximab ist eine effektive Therapie mit hoher Patientenzufriedenheit. Starke therapiebedingte Nebenwirkungen wie Fieber, Schüttelfrost und Kopfschmerzen nach Gabe von Rituximab könnten als Indikator für gute Wirksamkeit dienen. © 2017 Deutsche Dermatologische Gesellschaft (DDG).

    A plethora of methods have been developed over the years so that carbon dioxide can be used as a reactant in organic synthesis. Given the abundance of this compound, its utilization in synthetic chemistry, particularly on an industrial scale, is still at a rather low level. In the last 35 years, considerable research has been performed to find catalytic routes to transform CO2 into carboxylic acids, esters, lactones, and polymers in an economic way. This Review presents an overview of the available homogeneous catalytic routes that use carbon dioxide as a C1 carbon source for the synthesis of industrial products as well as fine chemicals.

    How can universities create engaged citizens and global leaders? Each year, a select group of advanced practice nursing students at Baylor University Louise Herrington School of Nursing travel to Africa for a month-long clinical mission experience. Students work alongside local and missionary healthcare providers in a comprehensive Christian outreach to the community at a high-volume clinic. Creating rich learning experiences in a global setting in significant and sustainable ways is difficult, but intentionally focusing on what we are called to do and who we serve provides ballast for faculty and students. The success of the trip in preparing students to be global influencers is evident by the work graduates elect to do around the world, following graduation.

    The aim of this study was to determine the value of a combined magnetic resonance imaging (MRI) protocol including steady-state free precession (SSFP) imaging, phase-contrast measurements and contrast-enhanced MR angiography (CE-MRA) for presurgical or preinterventional diagnostic imaging in patients with suspected atrial septum defects. Out of 65 MRI studies of patients with suspected atrial septum defects, 56 patients were included in the study. The atrial septum defects were identified on cine images. Velocity encoded flow measurements were used to determine shunt volumes, which were compared with invasive oxymetry in 24 patients. Contrast-enhanced MRI was used to assess the thoracic vessels in order to detect vascular anomalies. The findings were compared with the intraoperative results. A total of 24 patients with high shunt volumes were treated either surgically (16 patients) or interventionally (8 patients) and 32 patients with low shunt volumes did not require surgical or interventional treatment. The vascular anomaly, which in all cases was anomalous pulmonary venous return, was confirmed by the intraoperative findings. The type and location of atrial septal defects which required treatment, were confirmed intraoperatively or during the intervention. The results of shunt quantification by MRI showed a good correlation with the results of invasive oximetry (r=0.91, p <0.0001). A combined MRI protocol including cine SSFP images, velocity-encoded flow measurements and CE-MRA is an accurate method for preoperative and preinterventional evaluation of atrial septum defects.

    Laut einer Befragung im Jahre 2012 war der Umgang mit Antithrombotika bei dermatochirurgischen Eingriffen in Deutschland sehr heterogen. 2014 wurde erstmals eine evidenzbasierte Leitlinie zu diesem Thema veröffentlicht. Es wurde eine anonyme Befragung derselben Stichprobe zum Umgang mit Antithrombotika sowie zu Kenntnissen der Leitlinie durchgeführt. Die Ergebnisse wurden als relative Häufigkeiten berichtet und denen aus 2012 gegenübergestellt. 208 Antwortbögen wurden ausgewertet (Rücklaufquote: 36,6 %). Die große Mehrheit der Dermatologen erklärte, kleinere Eingriffe unter Fortführung der Therapie mit Phenprocoumon, niedrig dosierter Acetylsalicylsäure (≤ 100 mg) und Clopidogrel sowie mit direkten oralen Antikoagulanzien durchzuführen. Bei größeren Eingriffen war der Umgang hingegen weiterhin heterogen, insbesondere unter niedergelassenen Dermatologen. Der Anteil der Dermatologen, die Phenprocoumon, Acetylsalicylsäure und Clopidogrel leitlinienkonform verwendeten, hat sich insgesamt vergrößert. Führten 2012 beispielsweise 53,8 % der Klinikärzte bzw. 36,3 % der niedergelassenen Dermatologen eine große Exzision unter Fortführung der Therapie mit niedrig dosierter Acetylsalicylsäure durch, taten dies 2017 90,2 % bzw. 57,8 % (Phenprocoumon: 33,8 % bzw. 11,9 % auf 63,9 % bzw. 29,9 %; Clopidogrel: 36,9 % bzw. 23,2 % auf 63,9 % bzw. 30,6 %). Unter den Klinikärzten war ein hoher Anteil mit der Leitlinie vertraut und fand diese hilfreich. Eine Zunahme des leitlinienkonformen Verhaltens war bei allen Eingriffen zu verzeichnen.

    Die Pustulosis palmoplantaris ist eine chronisch entzündliche Hauterkrankung, die mit bedeutenden Einschränkungen der Lebensqualität und der Belastbarkeit einhergeht. Aufgrund von Zulassungsbeschränkungen und einem häufig therapierefraktären Verlauf sind die Behandlungsmöglichkeiten limitiert. Nach zuvor frustranen Therapien erhielten 9 Patienten mit Pustulosis palmoplantaris nach Ausschluss einer latenten Tuberkulose Ustekinumab (45 mg Ustekinumab bei  100 kg KG) in Woche 0, 4, 12 und 24. Reguläre Visiten erfolgten nach 4 und 12 Wochen, im weiteren Verlauf alle 12 Wochen. Das Durchschnittsalter bei Therapiebeginn betrug 48 Jahre. Drei Patienten waren männlich. Bei n  =  4 Patienten (44,4 %) wurde eine Verbesserung um 75 % des Palmoplantar-Psoriasis-Area-Severity-Index (PPPASI) erreicht. Insgesamt verbesserte sich der PPPASI nach 24 Wochen durchschnittlich um 71,6 %. Eine komplette Abheilung zeigte sich bei n  =  2 Patienten nach 24 Wochen. Bis auf lokale Injektionsreaktionen und leichte Infekte wurden keine unerwünschten Wirkungen beobachtet. Die Fallserie ist ein weiterer Beleg für die Wirksamkeit und Verträglichkeit von Ustekinumab in der Therapie der Pustulosis palmoplantaris. Zur Beurteilung der Langzeitwirkung und -sicherheit sowie der Wirksamkeit einer intermittierenden Therapie sind kontrollierte Studiendaten sowie Beobachtungen im Rahmen von Patientenregistern notwendig. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

    2017-09-06

    To provide body weight support during walking and balance training, one can employ two distinct embodiments: support through a harness hanging from an overhead system or support through a saddle/seat type. This paper presents a comparison of these two approaches. Ultimately, this comparison determined our selection of the body weight support system employed in the MIT-Skywalker, a robotic device developed for the rehabilitation/habilitation of gait and balance after a neurological injury. Here we will summarize our results with eight healthy subjects walking on the treadmill without any support, with 30% unloading supported by a harness hanging from an overhead system, and with a saddle/seat-like support system. We compared the center of mass as well as vertical and mediolateral trunk displacements across different walking speeds and support. The bicycle/saddle system had the highest values for the mediolateral inclination, while the overhead harness body weight support showed the lowest values at all speeds. The differences were statistically significant. We selected the bicycle/saddle system for the MIT-Skywalker. It allows faster don-and-doff, better centers the patient to the split treadmill, and allows all forms of training. The overhead harness body weight support might be adequate for rhythmic walking training but limits any potential for balance training.

Das Gesamtsystem kann von beliebiger Topologie sein, und die Zahl der die Segmente verkoppelnden Hohlleiter- Moden ist nicht begrenzt. Als Ergebnis steht bei offenen Strukturen deren vollständige S-Matrix, bei abgeschlossenen deren Resonanzeigenschaften zur Verfügung. Die theoretischen Grundlagen werden beschrieben und die Anwendung mit Beispielen aus dem Gebiet der Teilchenbeschleuniger und zu Eigenschaften schwach elliptisch geformter Resonatoren illustriert. A method called Coupled S-Parameter Calculation – CSC is described which is used to calculate the rf properties of complex structures, i.e. either their scattering (devices with ports or their resonance properties. The method is based on the segmentation of the entire system into sections being less complex, the external calculation of the section’s broadband S-matrices, and a combination scheme, which is applicable to any topology and number of modes. The method’s principle is described. Examples from the field of particle accelerator cavities and about the properties of weakly elliptical resonators are given.

    2005-01-01

    A fissile materials irradiation capability has been developed at the Massachusetts Institute of Technology (MIT) Research Reactor (MITR) to support nuclear engineering studies in the area of advanced fuels. The focus of the expected research is to investigate the basic properties of advanced nuclear fuels using small aggregates of fissile material. As such, this program is intended to complement the ongoing fuel evaluation programs at test reactors. Candidates for study at the MITR include vibration-packed annular fuel for light water reactors and microparticle fuels for high-temperature gas reactors. Technical considerations that pertain to the design of the MITR facility are enumerated including those specified by 10 CFR 50 concerning the definition of a research reactor and those contained in a separate license amendment that was issued by the U.S. Nuclear Regulatory Commission to MIT for these types of experiments. The former includes limits on the cross-sectional area of the experiment, the physical form of the irradiated material, and the removal of heat. The latter addresses experiment reactivity worth, thermal-hydraulic considerations, avoidance of fission product release, and experiment specific temperature scrams

    This research project was sponsored by the federal ministry of science and technology BMFT (product owner: New Materials and Chemical Technologies - NMT). Its aim was to develop a novel unit that can work both as a pump and a turbine with a constant flow direction through internal blade adjustment. This specifically high-speed pump-turbine is suited for plants where a liquid in one case needs to be hauled against a rising pressure and where, in another case, there is a pressure drop in the same direction. So far, either a separate pump and turbine each are used which are temporarily stopped, involving corresponding effort, or - almost as a rule - the turbine is dispensed with, so that the energy locked up in the pressure drop goes unused. (orig.) [Deutsch] Die Zielsetzung unseres Forschungsvorhabens, das vom BMFT (Produkttraeger: Neue Materialien und Chemische Technologien - NMT) gefoerdert wird, war die Entwicklung eines neuartigen Aggregats, das durch interne Schaufelverstellung in der Lage ist, sowohl als Pumpe als auch als Turbine mit gleichbleibender Durchstroemrichtung zu arbeiten. Diese spezifisch schnellaeufige Pumpturbine kommt fuer Anlagen in Frage, in denen eine Fluessigkeit im einen Fall gegen einen anstehenden Druck gefoerdert werden muss und im anderen Fall in gleicher Richtung ein Druckgefaelle zur Verfuegung steht. Entweder werden bisher getrennt aufgestellte Pumpen und Turbinen mit zeitweisem Stillstand und entsprechendem Aufwand eingesetzt oder es wird - fast in der Regel - auf die Turbine und damit auf die im Druckgefaelle enthaltene Energie verzichtet.

    2007-06-01

    Partielle Differentialgleichungen des Reaktions-Diffusions-Typs beschreiben Phänomene wie Musterbildung, nichtlineare Wellenausbreitung und deterministisches Chaos und werden oft zur Untersuchung komplexer Vorgänge auf den Gebieten der Biologie, Chemie und Physik herangezogen. Zellulare Nichtlineare Netzwerke (CNN) sind eine räumliche Anordnung vergleichsweise einfacher dynamischer Systeme, die eine lokale Kopplung untereinander aufweisen. Durch eine Diskretisierung der Ortsvariablen können Reaktions-Diffusions-Gleichungen häufig auf CNN mit nichtlinearen Gewichtsfunktionen abgebildet werden. Die resultierenden Reaktions-Diffusions-CNN (RD-CNN) weisen dann in ihrer Dynamik näherungsweise gleiches Verhalten wie die zugrunde gelegten Reaktions-Diffusions-Systeme auf. Werden RD-CNN zur Identifikation neuronaler Strukturen anhand von EEG-Signalen herangezogen, so besteht die Möglichkeit festzustellen, ob das gefundene Netzwerk lokale Aktivität aufweist. Die von Chua eingeführte Theorie der lokalen Aktivität Chua (1998); Dogaru und Chua (1998) liefert eine notwendige Bedingung für das Auftreten von emergentem Verhalten in zellularen Netzwerken. Änderungen in den Parametern bestimmter RD-CNN könnten auf bevorstehende epileptische Anfälle hinweisen. In diesem Beitrag steht die Identifikation neuronaler Strukturen anhand von EEG-Signalen durch Reaktions-Diffusions-Netzwerke im Vordergrund der dargestellten Untersuchungen. In der Ergebnisdiskussion wird insbesondere auch die Frage nach einer geeigneten Netzwerkstruktur mit minimaler Komplexität behandelt.

    The MIT HEDP Accelerator Facility utilizes a 135-keV, linear electrostatic ion accelerator; DT and DD neutron sources; and two x-ray sources for development and characterization of nuclear diagnostics for OMEGA, Z, and the NIF. The accelerator generates DD and D3He fusion products through the acceleration of D+ ions onto a 3He-doped Erbium-Deuteride target. Accurately characterized fusion product rates of around 106 s- 1 are routinely achieved. The DT and DD neutron sources generate up to 6×108 and 1×107 neutrons/s, respectively. One x-ray generator is a thick-target W source with a peak energy of 225 keV and a maximum dose rate of 12 Gy/min; the other uses Cu, Mo, or Ti elemental tubes to generate x-rays with a maximum energy of 40 keV. Diagnostics developed and calibrated at this facility include CR-39-based charged-particle spectrometers, neutron detectors, and the particle Time-Of-Flight (pTOF) and Magnetic PTOF CVD-diamond-based bang time detectors. The accelerator is also a valuable hands-on tool for graduate and undergraduate education at MIT. This work was supported in part by the U.S. DoE, SNL, LLE and LLNL.

    Yields and product compositions of pyrolysis reactions depend on the mode of heat supply, the temperature level, and the time of residue at reaction temperature. Using hot circulating granular materials mixed with solid or liquid materials (e.g. biogenic or hydrocarbon-rich residues and waste materials or refinery residues), the following important processes can be investigated: Separation of pyrolysis reaction and heat supply - accurate, optimal temperature levels for pyrolysis, e.g. between 5000 and 850 degrees centigrade - undiluted, unmixed pyrolysis gas - short times of residue of the pyrolysis gas for suppression of secondary reactions.

    To explore the meaning of “global culture” in a professional communication context, this paper explores the “unsettled” global culture of Vatel, a private business school educating students from nearly 50 different countries for the hospitality industry. This paper explores the role of knowledge...... management in understanding global culture, arguing that the notion of “unsettled” cultures demonstrates how ideologies function in global settings and draw on national “settled” cultural resources. In unpacking different aspects of Vatel's culture this paper questions assumptions built into cultural frames...... of reference by offering a global culture frame, drawing on cultural resources from country based “settled” cultural contexts, and reflects on how global cultural contexts can benefit from a knowledge management approach to this dynamic between “settled” cultural contexts and “unsettled” cultural ideologies...

    Full Text Available Abstract Background Smoking is a leading cause of morbidity and mortality globally. There is therefore need to identify relevant factors associated with smoking among adolescents in order to better tailor public health interventions aimed at preventing smoking. Methods We used data from the Global Youth Tobacco Survey (GYTS conducted in 2003 in Punjab, India, on 2014 adolescents of whom 58.9% were males. We conducted a weighted logistic regression analysis, adjusting for age and sex, to determine associations between predictor variables and current tobacco smoking status. Results A total of 2014 adolescents participated in the survey in 2003, and of these 58.9% were males. Male respondents tended to be older than females (21.2% of males, and 13.1% of females were of age 16 years or above. The percent of males and females in the other age groups were: 23.0% and 28.6% for Conclusion The observed associations between current smoking on one hand and peer smoking, and perception that boys who smoke are less attractive on the other, deserve further studies. The factors reported in the current study should be considered in the design of public health interventions aimed to reduce adolescent cigarette smoking.

  12. A MIT-Based Nonlinear Adaptive Set-Membership Filter for the Ellipsoidal Estimation of Mobile Robots' States

    Full Text Available The adaptive extended set-membership filter (AESMF for nonlinear ellipsoidal estimation suffers a mismatch between real process noise and its set boundaries, which may result in unstable estimation. In this paper, a MIT method-based adaptive set-membership filter, for the optimization of the set boundaries of process noise, is developed and applied to the nonlinear joint estimation of both time-varying states and parameters. As a result of using the proposed MIT-AESMF, the estimation effectiveness and boundary accuracy of traditional AESMF are substantially improved. Simulation results have shown the efficiency and robustness of the proposed method.

    Results of calculations of physical parameters characterizing the TRX, MIT and BETTIS critical assemblies obtained according to the program TRIFON are presented. The program TRIFON permits to calculate the space-energy neutron distribution in the multigroup approximation in a multizone cylindrical cell. Results of comparison of the TRX, BETTIS and MIT crytical assembly parameters with experimental data and calculational results according to the Monte Carlo method are presented as well. Deviations of the parameters are in the range of 1.5-2 of experimental errors. Data on the interference of uranium 238 levels in the resonant neutron absorption in the cell are given [ru

  18. Distinct Mechanisms of Recognizing Endosomal Sorting Complex Required for Transport III (ESCRT-III) Protein IST1 by Different Microtubule Interacting and Trafficking (MIT) Domains*

    The endosomal sorting complex required for transport (ESCRT) machinery is responsible for membrane remodeling in a number of biological processes including multivesicular body biogenesis, cytokinesis, and enveloped virus budding. In mammalian cells, efficient abscission during cytokinesis requires proper function of the ESCRT-III protein IST1, which binds to the microtubule interacting and trafficking (MIT) domains of VPS4, LIP5, and Spartin via its C-terminal MIT-interacting motif (MIM). Here, we studied the molecular interactions between IST1 and the three MIT domain-containing proteins to understand the structural basis that governs pairwise MIT-MIM interaction. Crystal structures of the three molecular complexes revealed that IST1 binds to the MIT domains of VPS4, LIP5, and Spartin using two different mechanisms (MIM1 mode versus MIM3 mode). Structural comparison revealed that structural features in both MIT and MIM contribute to determine the specific binding mechanism. Within the IST1 MIM sequence, two phenylalanine residues were shown to be important in discriminating MIM1 versus MIM3 binding. These observations enabled us to deduce a preliminary binding code, which we applied to provide CHMP2A, a protein that normally only binds the MIT domain in the MIM1 mode, the additional ability to bind the MIT domain of Spartin in the MIM3 mode.

  20. Global Mindsets

    DEFF Research Database (Denmark)

    Global Mindsets: Exploration and Perspectives seeks to tackle a topic that is relatively new in research and practice, and is considered by many to be critical for firms seeking to conduct global business. It argues that multiple mindsets exist (across and within organizations), that they operate...... in a global context, and that they are dynamic and undergo change and action. Part of the mindset(s) may depend upon place, situation and context where individuals and organizations operate. The book will examine the notion of "mindset" is situational and dynamic, especially in a global setting, why...... it is important for future scholars and managers and how it could be conceptualized. Global Mindsets: Exploration and Perspectives is split into two major sections; the first examines where the literature currently is with respect to the knowledge in the field and what conceptual frameworks guide the thinking...
