Liver transplantation: current status and future prospects

The enormous progress that has been made in liver transplantation over the past two decades has culminated in survival approaching 90% at 12 months. The success of the procedure combined with the widening spectrum of disease processes deemed amenable to liver transplantation has meant that there are too few donors for those awaiting transplantation. This has extrapolated to many patients having such advanced disease by the time a suitable donor liver is available, that they are almost non-transplantable. The immediate options facing the transplant community are to decrease the number of patients listed or to increase the number of living donor transplants. Alternatives to liver transplantation such as hepatocyte transplantation, gene therapy, xenotransplantation and the bioartificial liver are being sought but, at best, are some way from clinical application. It is anticipated that a number of liver diseases that are indications for liver transplantation at this time will have progression arrested or will be cured by medical therapy in the future.

Brazil and the USA: rethinking the future of ethanol for stronger mutual wns

A produção de etanol e a dominação da indústria, historicamente, tem sido uma fonte de discórdia para seus dois principais produtores. Os EUA com seu etanol de milho e o Brasil com sua etanol de cana, são os dois maiores produtores mundiais de etanol (1º EUA; 2º Brasil) e tem competido pela participação de mercado mundial há décadas. A partir de Dezembro de 2011, os EUA levantaram as tarifas e os subsídios que foram instalados para proteger sua indústria de etanol, o que muda o campo de jogo da produção mundial de etanol para o futuro. Atualmente em todo o mundo, o etanol é usado em uma proporção muito menor comparativamente a outros combustíveis. Esta pesquisa analisa o nível potencial de colaboração entre os EUA e o Brasil, facilitando um diálogo entre os stakeholders em etanol. A pesquisa consiste principalmente de conversas e entrevistas, com base em um conjunto de perguntas destinadas a inspirar conversas detalhadas e expansivas sobre os temas de relações Brasil-EUA e etanol. Esta pesquisa mostra que o etanol celulósico, que é também conhecido como etanol de segunda geração, oferece mais oportunidades de parceria entre os EUA e o Brasil, como há mais oportunidades para pesquisa e desenvolvimento em conjunto e transferência de tecnologia nesta área. Enquanto o etanol de cana no Brasil ainda é uma indústria próspera e crescente, o milho e a cana são muito diferentes geneticamente para aplicar as mesmas inovações exatas de um etanol de primeira geração, por outro. As semelhanças entre os processos de fermentação e destilação entre as matérias-primas utilizadas nos EUA e no Brasil para o etanol de segunda geração torna o investimento conjunto nesta área mais sensível. De segunda geração é uma resposta para a questão "alimentos versus combustíveis". Esta pesquisa aplica o modelo de co-opetição como um quadro de parceria entre os EUA e o Brasil em etanol celulósico. A pesquisa mostra que enquanto o etanol pode não ser um forte concorrente com o petróleo no futuro imediato, ele tem melhores perspectivas de ser desenvolvido como um complemento ao petróleo, em vez de um substituto. Como os EUA e o Brasil tem culturas de misturar etanol com petróleo, algo da estrutura para isso já está em vigor, a relação de complementaridade seria fortalecido através de uma política de governo clara e de longo prazo. A pesquisa sugere que apenas através desta colaboração, com toda a partilha de conhecimentos técnicos e estratégias econômicas e de desenvolvimento, o etanol celulósico será um commodity negociado mundialmente e uma alternativa viável a outros combustíveis. As entrevistas com os interessados em que esta pesquisa se baseia foram feitas ao longo de 2012. Como a indústria de etanol é muito dinâmica, certos eventos podem ter ocorrido desde esse tempo para modificar ou melhorar alguns dos argumentos apresentados.

Investing Effectively in Information and Communication Technology in Schools, 2008-2013

Learning is changing. A pivotal force in bringing about this change is the use of information and communications technology (ICT) which provides richer, more immediate, world-relevant educational resources and opportunities. When used well, ICT enriches learning and enhances teaching. It invigorates classroom activities and is a powerful motivational tool that encourages learners to progress in more personalised and self-directed ways. Ireland has achieved rapid change and growth in the past decade, but to sustain this we must prepare the next generation for the knowledge society in which they will live. The challenge we face is to ensure that the emphasis on ICT in schools shifts, in the immediate future, from technology provision to a focus on its deliberate use by the learner. Fostering personal creativity has always been a desirable educational value. The pursuit of creativity and inventiveness are now pivotal skills in a knowledge economy and the embedding of ICT in learning can greatly facilitate their development. Web 2.0 will facilitate greater interactivity and enable greater levels of user-generated content. It is crucial that young people acquire the ICT and related skills to support these new opportunities.

Road Safety Audit for the US 61/Harrison Street and West Locust Street Intersection in Davenport-Scott County, Iowa, 2008

On the October 7 and 8, 2008, a road safety audit was conducted for the intersection of US 61/Harrison Street and West Locust Street in Davenport, Iowa. US 61/Harrison Street is a one-way street and a principal arterial route through Davenport, with three southbound lanes. Locust Street is a four-lane, two-way minor arterial running across the city from west to east. The last major improvement at this intersection was implemented approximately 20 years ago. The Iowa Department of Transportation requested a safety audit of this intersection in response to a high incidence of crashes at the location over the past several years, in view of the fact that no major improvements are anticipated for this intersection in the immediate future. The road safety audit team discussed current conditions at the intersection and reviewed the last seven years of crash data. The team also made daytime and nighttime field visits to the intersection to examine field conditions and observe traffic flow and crossing guard operations with younger pedestrians. After discussing key issues, the road safety audit team drew conclusions and suggested possible enforcement, engineering, public information, and educational strategies for mitigation.

Cooperació i teoria de jocs, el programari lliure o el #15m, dos exemples per l'universitat

Xerrada de cloenda de la Setmana internacional d'accés obert 2011 a la UOC, a càrrec de l'advocat Josep Jover. Per què les estratègies altruistes guanyen les egoistes en el programari lliure i en el #15m? El moviment #15m, igual que el programari, a diferència dels béns materials, no es pot posseir, ja que en pot gaudir (formant-ne part) un nombre indeterminat de persones sense que per això hagi de privar ningú de tenir-lo al seu torn. I això porta a girar com un mitjó la manera com manegen la informació les universitats, i quina és la missió de la universitat en la nova societat. En el futur immediat, valorarem les universitats no per la informació que guarden, que fora sempre serà millor i més extensa, sinó per la capacitat de crear masses crítiques, sia de recerca de coneixement, de capacitació humana, d'enllaç entre iguals... Les universitats hauran d'implantar el model o quedaran relegades.

Cooperation and game theory, free software or the #15m movement: Two examples for universities

Closing talk of the Open Access Week 2011 at the UOC, by Josep Jover. Why do altruistic strategies beat selfish ones in the spheres of both free software and the #15m movement? The #15m movement, like software but unlike tangible goods, cannot be owned. It can be used (by joining it) by an indeterminate number of people without depriving anyone else of the chance to do the same. And that turns everything on its head: how universities manage information and what their mission is in this new society. In the immediate future, universities will be valued not for the information they harbour, which will always be richer and more extensive beyond their walls, but rather for their capacity to create critical masses, whether of knowledge research, skill-building, or networks of peers... universities must implement the new model or risk becoming obsolete.

Young people and youth policies in Spain in times of austerity: between juggling and the trapeze

The aim of this article is to present and discuss the situation regarding young people and youth policy in Spain via the parameters of the magic triangle linking policy, research and action: (1) the situation of young people in Spain today -some indicators are highlighted regarding the main challenges and opportunities for young people, with references to the so-called"Ni-Nis" (neither studying nor working)- and the movement of the"outraged" youth that occupied the streets of Spain"s major cities in May 2011; (2) the current approaches adopted by public youth policies in Spain and limitations and difficulties encountered by the government in attempting to meet the demands of young people; (3) social work with young people and professionals involved in youth policies. In the last section, we conclude with some open questions and proposals for the immediate future

IDEAS for Strategic Technology Management: Design of an electronically mediated scenario method

The age-old adage goes that nothing in this world lasts but change, and this generation has indeed seen changes that are unprecedented. Business managers do not have the luxury of going with the flow: they have to plan ahead, to think strategies that will meet the changing conditions, however stormy the weather seems to be. This demand raises the question of whether there is something a manager or planner can do to circumvent the eye of the storm in the future? Intuitively, one can either run on the risk of something happening without preparing, or one can try to prepare oneself. Preparing by planning for each eventuality and contingency would be impractical and prohibitively expensive, so one needs to develop foreknowledge, or foresight past the horizon of the present and the immediate future. The research mission in this study is to support strategic technology management by designing an effective and efficient scenario method to induce foresight to practicing managers. The design science framework guides this study in developing and evaluating the IDEAS method. The IDEAS method is an electronically mediated scenario method that is specifically designed to be an effective and accessible. The design is based on the state-of-the-art in scenario planning, and the product is a technology-based artifact to solve the foresight problem. This study demonstrates the utility, quality and efficacy of the artifact through a multi-method empirical evaluation study, first by experimental testing and secondly through two case studies. The construction of the artifact is rigorously documented as justification knowledge as well as the principles of form and function on the general level, and later through the description and evaluation of instantiations. This design contributes both to practice and foundation of the design. The IDEAS method contributes to the state-of-the-art in scenario planning by offering a light-weight and intuitive scenario method for resource constrained applications. Additionally, the study contributes to the foundations and methods of design by forging a clear design science framework which is followed rigorously. To summarize, the IDEAS method is offered for strategic technology management, with a confident belief that it will enable gaining foresight and aid the users to choose trajectories past the gales of creative destruction and off to a brighter future.

Casa Dental Eduardo Daza Ltda. Un estudio de caso de perdurabilidad empresarial

Este trabajo presenta un estudio de caso de perdurabilidad empresarial de la empresa Casa Dental Eduardo Daza Ltda, que como Empresa de Familia, desafía la tendencia de su desaparición a partir de la tercera generación, como lo han hecho la mayoría de empresas de esta naturaleza a nivel mundial. En primera instancia se contextualiza y caracteriza las empresas de familia a nivel mundial a partir de una revisión de la literatura existente, para poder consolidar un marco referencial que permite una aproximación al estado del arte en el ámbito corporativo de empresas de naturaleza familiar, para luego analizar su dinámica actual en la economía colombiana, en un enfoque desde lo general a lo particular. Posteriormente se presenta las características que demarcan el éxito de las empresas de familia, su gestión y gobernabilidad, el protocolo de traspaso y el direccionamiento estratégico hacia la innovación como sinónimo que garantiza la perdurabilidad en el tiempo. Después de esta contextualización, se presenta las particularidades desde un contexto histórico de la empresa Casa Dental Eduardo Daza Ltda, sus vicisitudes corporativas, su decadencia y renacer, hasta convertirse en un caso de éxito empresarial a nivel de empresa de familia, sustentando en su comportamiento económico financiero en los últimos tres años, para poder definir sus particularidades, tendencias y prospectiva en el inmediato futuro. Se concluye que las empresas de familia como forma más antigua de organización empresarial, tienen un amplio reconocimiento como un actor importante y diferenciador de la economía mundial, pues el aparato productivos de muchos países desarrollados y en vías de desarrollo se soporta en empresas de familia. La evidencia empírica señala dos características distintivas de las empresas de familia: 1) en casi todos los países estas empresas tienen una alta participación en la creación de riqueza; y 2) tienen una alta probabilidad de desaparecer. En todas las economías, en mayor o menor grado, conviven estos dos fenómenos tan significativos: su importancia económica y su vulnerabilidad

The use of land-sea warming contrast under climate change to improve impact metrics

A favoured method of assimilating information from state-of-the-art climate models into integrated assessment models of climate impacts is to use the transient climate response (TCR) of the climate models as an input, sometimes accompanied by a pattern matching approach to provide spatial information. More recent approaches to the problem use TCR with another independent piece of climate model output: the land-sea surface warming ratio (φ). In this paper we show why the use of φ in addition to TCR has such utility. Multiple linear regressions of surface temperature change onto TCR and φ in 22 climate models from the CMIP3 multi-model database show that the inclusion of φ explains a much greater fraction of the inter-model variance than using TCR alone. The improvement is particularly pronounced in North America and Eurasia in the boreal summer season, and in the Amazon all year round. The use of φ as the second metric is beneficial for three reasons: firstly it is uncorrelated with TCR in state-of-the-art climate models and can therefore be considered as an independent metric; secondly, because of its projected time-invariance, the magnitude of φ is better constrained than TCR in the immediate future; thirdly, the use of two variables is much simpler than approaches such as pattern scaling from climate models. Finally we show how using the latest estimates of φ from climate models with a mean value of 1.6—as opposed to previously reported values of 1.4—can significantly increase the mean time-integrated discounted damage projections in a state-of-the-art integrated assessment model by about 15 %. When compared to damages calculated without the inclusion of the land-sea warming ratio, this figure rises to 65 %, equivalent to almost 200 trillion dollars over 200 years.

When rules and principles are not enough: insiders’ views and narratives on the global financial crisis

Much has been written about Wall Street and the global financial crisis (GFC). From a fraudulent derivatives market to a contestable culture of banking bonuses, culpability has been examined within the frames of American praxis, namely that of American exceptionalism. This study begins with an exploratory analysis of non-US voices concerning the nature of the causes of the GFC. The analysis provides glimpses of the globalized extent of assumptions shared, but not debated within the globalization convergence of financial markets as the neo-liberal project. Practical and paradigmatic tensions are revealed in the capture of a London-based set of views articulated by senior financial executives of financial service organizations, the outcomes of which are not overly optimistic for any significant change in praxis within the immediate future.

Cashew cultivation, access to land and food security in Brong-Ahafo Region, Ghana: Preventing the intergenerational transmission of poverty

This research aimed to investigate the implications of changing agricultural land use from food production towards increased cashew cultivation for food security and poverty alleviation in Jaman North District, Brong-Ahafo Region of Ghana. Based on qualitative, participatory research with a total of 60 participants, the research found that increased cashew production had led to improvements in living standards for many farmers and their children over recent years. Global demand for cashew is projected to continue to grow rapidly in the immediate future and cashew-growing areas of Ghana are well placed to respond to this demand. Cashew farmers however were subject to price fluctuations in the value of Raw Cashew Nuts (RCN) due to unequal power relations with intermediaries and export buyer companies and global markets, in addition to other vulnerabilities that constrained the quality and quantity of cashew and food crops they could produce. The expansion of cashew plantations was leading to pressure on the remaining family lands available for food crop production, which community members feared could potentially compromise the food security of rural communities and the land inheritance of future generations.

Assessing and applying evidence-based interventions at the community level in India as a model policy to reduce neonatal mortality rates in Nigeria

Background. The United Nations' Millennium Development Goal (MDG) 4 aims for a two-thirds reduction in death rates for children under the age of five by 2015. The greatest risk of death is in the first week of life, yet most of these deaths can be prevented by such simple interventions as improved hygiene, exclusive breastfeeding, and thermal care. The percentage of deaths in Nigeria that occur in the first month of life make up 28% of all deaths under five years, a statistic that has remained unchanged despite various child health policies. This paper will address the challenges of reducing the neonatal mortality rate in Nigeria by examining the literature regarding efficacy of home-based, newborn care interventions and policies that have been implemented successfully in India. ^ Methods. I compared similarities and differences between India and Nigeria using qualitative descriptions and available quantitative data of various health indicators. The analysis included identifying policy-related factors and community approaches contributing to India's newborn survival rates. Databases and reference lists of articles were searched for randomized controlled trials of community health worker interventions shown to reduce neonatal mortality rates. ^ Results. While it appears that Nigeria spends more money than India on health per capita ($136 vs. $132, respectively) and as percent GDP (5.8% vs. 4.2%, respectively), it still lags behind India in its neonatal, infant, and under five mortality rates (40 vs. 32 deaths/1000 live births, 88 vs. 48 deaths/1000 live births, 143 vs. 63 deaths/1000 live births, respectively). Both countries have comparably low numbers of healthcare providers. Unlike their counterparts in Nigeria, Indian community health workers receive training on how to deliver postnatal care in the home setting and are monetarily compensated. Gender-related power differences still play a role in the societal structure of both countries. A search of randomized controlled trials of home-based newborn care strategies yielded three relevant articles. Community health workers trained to educate mothers and provide a preventive package of interventions involving clean cord care, thermal care, breastfeeding promotion, and danger sign recognition during multiple postnatal visits in rural India, Bangladesh, and Pakistan reduced neonatal mortality rates by 54%, 34%, and 15–20%, respectively. ^ Conclusion. Access to advanced technology is not necessary to reduce neonatal mortality rates in resource-limited countries. To address the urgency of neonatal mortality, countries with weak health systems need to start at the community level and invest in cost-effective, evidence-based newborn care interventions that utilize available human resources. While more randomized controlled studies are urgently needed, the current available evidence of models of postnatal care provision demonstrates that home-based care and health education provided by community health workers can reduce neonatal mortality rates in the immediate future.^
