Mohammed's family was forced to leave Palestine long before he was born, with no opportunity for return. Instead, Mohammed has lived most of his life between Saudi Arabia and Greece, which became his second home. For three weeks Mohammed joined dozens of Greek, Arab and Western volunteers in preparing the Greek ship Eleftheri Mesogeios (,Free Mediterranean'), to carry 2000 tons of humanitarian aid, including prefabricated houses and hospital equipment, to Gaza. The ship formed part of the Gaza Freedom Flotilla, an international effort by volunteers from 36 countries that aimed to send eight ships to Gaza, carrying 700 passengers and 10,000 tonnes of humanitarian aid, in an attempt to prise open the strict embargo Israel has imposed on the Gaza strip since 2007. The Israeli army attacked the flotilla in international waters, killing eight Turkish nationals and one Turkish-American national, and injuring many more. Flotilla participants were placed behind bars. Intending to propagate their own version of events, the Israeli authorities confiscated audio-visual records made by witnesses. As an ethnographer invited to participate in the flotilla, Nikolas Kosmatopoulos was a witness to the events that took place. His notes are published in the form of a narrative in this issue of ANTHROPOLOGY TODAY. Israel has so far rejected the UN's call for an international independent inquiry. The Turkish government has threatened to cut all ties with Israel unless it apologizes or agrees to such an inquiry. Back cover CLIMATE CHANGE ,There is no planet B': an estimated 100,000 people demonstrate at the Copenhagen Climate talks, 12 December 2009. Since the débâcle of the UN Climate talks in Copenhagen last December, a broad new global coalition of resistance has begun to emerge. It includes the Climate Camp protesters who took direct action against the coal-fired Kingsnorth power station and the fourth runway at Heathrow, the tens of thousands of demonstrators who joined the Wave in London in December and the estimated 100,000 who marched at Copenhagen. They join others who have intimate experience of melting sea ice and Andean glaciers, flooding in Bangladesh and New Orleans and droughts in Africa. In April, in Cochabamba, Bolivia, a conference of 35,000 people, many of them indigenous Americans, began to organize to protect themselves and Mother Earth , Pachamama , to avert catastrophic climate change. This new social movement poses a personal and professional challenge to anthropologists to integrate climate issues and global politics into the discipline and into their lives.

The festival includes endurance races of up to 36 kilometres over steep, rocky mountain paths and streams, a far cry from the bowling-green surfaces of Churchill Downs and Newmarket. Abdildechan, an expert in horse games in Kyzyl Suu, explained that horse games and competitions such as these derive from the importance of horses to the nomadic and warrior traditions of the Kyrgyz people. Horses enable people to move away from danger, he explained, and are also essential for work and food. Cars are becoming increasingly common in Kyrgyzstan, but many people believe that they will never completely replace horses in this mountainous region. ,Young people may have cars', says shepherd Jakshylyck Orgochor, ,but where there is a Kyrgyz person there is always a horse: a horse is a man's wings'. In this issue, Rebecca Cassidy scrutinizes claims about the distinctiveness of the Kyrgyz horse and considers the political consequences of evaluating domesticated animals on the basis of contested categories including ,breed' and ,type'. Back Cover: HUMAN-ANIMAL RELATIONS Ros Coard, lecturer in archaeology and specialist in archaeozoology and forensic taphonomy in the Department of Archaeology and Anthropology at the University of Wales Lampeter, examines forensic evidence taken from the scene of a suspected big cat kill in West Wales, UK. The skulls in the foreground belong to an array of known big cat species, and Coard compared tooth pit data from these skulls with those found in sheep and horses killed in unusual circumstances. These data have been used to provide evidence for the existence of at least one large predatory felid in West Wales. However, even without this scientific corroboration, many people around the UK report sightings of non-endemic ,alien' big cats (ABCs) on a regular basis, attributing to them an almost mythical status, and this makes them an interesting phenomenon to be considered from an anthropological perspective. Coard has been working collaboratively with Samantha Hurn, an anthropologist who has been documenting narratives relating to big cat sightings in West Wales. In this issue of ANTHROPOLOGY TODAY, Hurn outlines the data collected so far. She argues that ABCs do, indeed, exist in West Wales, and discusses how and why her informants from the local Welsh farming community regard these predators in positive terms. Many see ABCs as both important keystone species performing the valuable function of keeping other problematic predators (notably foxes) in check, and highly politicized animals who symbolize their own marginalized position within contemporary UK society. As Lévi-Strauss put it long ago, animal-human relations are, indeed, good to think with.

Among others adopting a critical perspective, the animal rights movement was outraged at claims made about red meat as a ,natural', ,healthy' and ,essential' part of the average Australian diet. Just as a prominent film star was recruited to the ,Red Meat , Feel Good' campaign, the hugely popular Missy Higgins was deployed to front the response from the animal rights movement. The youthful and fresh-faced Australian singer-songwriter, cuddling the vulnerable white piglet, iconically represents an informed, intelligent and humane vegetarian approach to the future in the relationship between human and non-human animals. Higgins here makes a striking plea for ,enlightenment'. Enlightenment of a different kind is offered by the poster reprinted on the back cover, where an Indian transvestite celebrates the joy of a minority gender identity. Although the rights of both human minorities and non-human animals may be ,universal', they must be rendered in culturally specific terms in order to be politically effective. Back cover Back cover: modern enlightenment in ancient sacred sites ,Be enlightened!' In 2006 ,Shelly Innocence' launched a new phone service in Bodhgaya, Bihar, offering customers the opportunity to receive personal text messages of EnlightenmentÔ on their mobile phones. Large billboards with images of this virtual transgendered guru were erected outside the main temple to advertise the service. Not only is Bodhgaya a site of inspiration for millions of Buddhists around the world, but the seat of enlightenment has also come to mean very different things as this cosmopolitan pilgrimage town goes global. For many decades the state of Bihar, where Bodhgaya is located, has been one of the least attractive destinations for pilgrims, tourists and anthropologists because of its notorious reputation as one of the most impoverished and ,lawless' states in the country. However in recent years the Mahabodhi Temple complex in Bodhgaya has become the object of global attention as a UNESCO World Heritage site, setting in motion a series of initiatives to encourage tourism and city development plans. As a result of new conservation policies and demands on the built environment, the World Heritage designation has become invested with a diverse set of claims and meanings by various stakeholders and religious communities. As a site of dense historical, religious and political significance, Bodhgaya today is a unique locus where spiritual and digital worlds collide in the shade of the bodhi tree.

One of the longest-serving pontiffs of modern times, and the only non-Italian to have been elected since the Dutch Adrian VI in the 1520s, Pope John Paul II died on 2 April and was buried on 8 April in the grottoes under St Peter's Basilica in Rome, the Tomb of the Popes. During this week unprecedented expressions of grief and mourning were displayed in Polish cities. Whole streets and squares were converted into temporary shrines, decorated with burning candles, flowers, papal portraits, letters to the departed Pope and both papal and Polish flags. The front cover shows a mother and daughter paying homage by lighting and placing candles along John Paul II Avenue, one of the biggest streets in central west Warsaw. The back cover shows a spontaneous memorial in the form of a large cross in Pilsudski Square, Warsaw, where John Paul II had celebrated mass during his first visit to Poland in 1979, the year after he was elected Pope. The memorial incorporates lanterns, flower offerings and a commemoration board made by primary school children. In constructing unofficial, vernacular and temporary commemorative sites from candles and flowers, Polish citizens re-enacted both the rituals of All Saints Day and the tradition of arranging flowers and candles in public places. The latter is, in the Polish context, more than an expression of grief provoked by deaths of important Polish personalities: it is also historically a way of expressing popularly shared feelings and values, and of asserting a degree of autonomy from the government of the day. Until 1990, Pope John Paul II symbolized powerful nationalist-Catholic sentiments that had helped Polish citizens stand up to communism. However, the slogan ,I didn't mourn the pope' which appeared on T-shirts made by a young Polish artists' group suggests that this new alliance between religion and official politics is being contested. Mourning rituals surrounding public figures frequently have a multivocal quality, and are barometers of change. As part of its ongoing engagement with public events, ANTHROPOLOGY TODAY invites debate on how collective memories are punctuated and shaped by historical moments such as these.

We are caught in a dilemma. For we are a meat-eating species, which gains much of its protein from consuming other animals. It is almost impossible to imagine that we will change, but we may, with sufficient will, find ways to minimise the pain we inflict on our fellow species.' Our front cover photo is taken from a publicity poster produced by SARC, the Southern Animal Rights Coalition, which is organizing the Southampton Cruelty Free Festival on 12 May (see www.crueltyfreefestival.com). In this issue of ANTHROPOLOGY TODAY, Jonathan Benthall asks why it is that, while anthropologists have studied most other social movements including environmentalism, little attention has been focused on the animal liberation and rights movement. The movement is underpinned by serious philosophical reflection and by its acknowledgment of Darwinism. This suggests that the shock caused by Darwin's discoveries is still being worked through nearly a century and a half later. Benthall's guest editorial outlines the ideological manifestations of the movement and also considers the implications of taking it seriously. Macfarlane's view, meanwhile, is that ,perhaps it will not be until some new and superior species emerges on earth, some computerised android, which breeds humans in tiny cages, force-feeds them, drains their bile, eats them, that we will seriously begin to crusade for the abolition of animal-on-animal cannibalism.' [source] Front and Back Covers, Volume 23, Number 1.ANTHROPOLOGY TODAY, Issue 1 2007February 200 Front and back cover caption, volume 23 issue 1 Front cover A Dutch participant in the reality television series Groeten uit de rimboe, in which Dutch and Belgian families immerse themselves in the daily life of the world's ,most primitive tribes'. Some time afterwards, their hosts pay a return visit to experience life in Europe, screened on television in the sequel Groeten terug. The two series have been subject to heated debate in the Dutch media, having been both lauded as unpretentious entertainment and condemned as unethical ,popular anthropology'. The attention of Myrna Eindhoven, Laurens Bakker and Gerard Persoon was first drawn to the series when a family was sent to Mentawai, where all three have done fieldwork. While they themselves are critical of the unashamed focus on entertainment, they became intrigued by the reactions of other anthropologists to the series. Here they connect this case from the Netherlands to the ongoing debate on ,popular anthropology' in ANTHROPOLOGY TODAY, triggered by the UK series Tribe. Dutch anthropologists have mostly dismissed the series as ,not anthropology', criticizing it as exploitative and as ethnocentric. But do anthropologists have the authority to define ,popular anthropology'? How do we come to terms with blatant commercialization of our fieldwork sites, and their conversion into exotic locations for popular entertainment? Back cover NATION-BUILDING IN EAST TIMOR East Timor celebrates its Independence Day on 20 May each year. The day forms the backdrop for the largest annual encounter between the political centre and the periphery. In this photo, an elder (katuas) member of Fretilin, the largest political party, blends traditional and modern at the Independence Day celebrations in the capital, Dili, in 2005. As an exemplar of the United Nations' capacity for ,nation-building', the Democratic Republic of Timor Leste (or ,East Timor' as it is more popularly known) developed into something of a ,poster boy' for the United Nations from the day it became a sovereign nation on 20 May 2002. But in April 2006, some months after the last remaining UN staff had left, violence in the streets of the capital began to undermine social and political stability, resulting in the overthrow of prime minister Mari Alkatiri. Under the more engaged leadership of his successor, José Ramos-Horta, the threat of unrest has abated to some extent. Nevertheless, the country faces an array of serious problems , political, social and economic. In his article in this issue, David Hicks draws on his anthropological fieldwork to highlight the widening gap between the ,centre' and the ,periphery'. Hicks argues that the former embodies the institutions and quasi-Western values professed by the national leaders in Dili, while the latter centres around the traditional, largely indigenous values of the country's local communities, who comprise the overwhelming majority of the population. Although already latent before the United Nations left, this widening divergence in values is eroding the political integrity of the first nation-state to become a member of the United Nations in the 21st century, and if it continues to grow, will call into question the ability of the United Nations to ,manufacture' nation-states. Anthropology has an important role to play in highlighting and analysing the implications of grassroots discrepancies between local populations and political elites. More than this, it has a role to play in confronting the international community with the ethical and other consequences of its increasingly regular interventions in third countries. [source] Front and Back Covers, Volume 21, Number 4.ANTHROPOLOGY TODAY, Issue 4 2005August 200 Front and back cover caption, volume 21 issue 4 Front cover The photo on the front cover, taken from the World Monuments Fund (WMF) website, shows house in Hilinawalö Mazingö, South Nias, Indonesia which was recently included on the WMF's List of 100 most endangered sites. Built in the 19th century, the house withstood the massive earthquake of 28 March 2005 that reduced the port towns of Nias to rubble and made over 150,000 people homeless. Constructed without nails, its complex structure can absorb tremors where modern concrete houses collapse. However, the hardwoods needed to replace columns and panels damaged by fire, rain and insects are no longer available, since Nias has been stripped of primary forest. Urgent conservation work is needed if the stone-paved villages and traditional architecture of Nias are to survive further destruction. In order to house the homeless, reconstruction planners are now studying the possibility of reviving traditional designs using cheaper, renewable materials. South Nias, whose plight was barely reported in the aftermath of the earthquake, received no government attention until ten days after the disaster. In his article on pp. 5-7 of this issue, Andrew Beatty reflects on the lack of development in Nias since he began fieldwork there in 1986 and considers the context of the recovery operation, showing how selective reporting, narrowly focused on stereotypical human interest stories, has failed to address local conditions, allowing corruption and inefficiency to thrive. Local knowledge is key to the success of aid. But only better reporting of regional power structures and stakeholders, combined with greater scrutiny of official dealings, will help to ensure that aid reaches those most in need. Back cover POLICY AND RACE The back cover reproduces questions from recent censuses conducted in England and Wales (above) and the USA (below). The former asks the respondent to state 'your ethnic group'; the latter seeks information on a 'person's race'. Statistics from the responses to these questions are given on page 4 of this issue. The British census question on ethnic origin, first introduced in 1991, is unusual in the European context. The 2001 census introduced a new 'mixed' category, as well as the term 'British' as a qualifier (to permit identification as British Black or British Asian), and a 'white' category subdivided into British, Irish and others. It also included a question on religion for the first time in more than a century, in response to the concerns of those for whom ethnic affiliation relates closely to religion (e.g. South Asian Muslims). In the US, the census of 2000 offered individuals, for the first time, the opportunity to identify themselves as belonging to more than one racial category (previously people of mixed descent were asked to choose a single racial category or to respond as 'some other race'). Most countries conduct regular censuses of their populations. In 1995 the United Nations Assembly passed a resolution calling on all its member countries to compile census data by 2004. However, a census depends on the consent of the population. Germany has not taken a full census since 1987, after postponing its scheduled 1983 census because of public concern over the proposed use of census returns to update local population registers; the Netherlands has not had a census since 1971, when high rates of refusal rendered returns unreliable. In common with a number of other countries, including Denmark, these two have turned to alternative data sources, particularly population and housing registers as well as sample surveys, for population statistics. The discourse of governance and perceptions of social category are powerfully influenced by the terms officially sanctioned by governments for the classification of citizens. The US census identifies its use of race as 'sociopolitical constructs' that are not 'scientific or anthropological in nature' (quickfacts.census.gov/qfd/meta/long_68186.htm). Race is surely one of the most potent and elusive of concepts anthropology is trying to make sense of, whether as a scientific or as a cultural category. In this issue of AT, Michael Banton contends that contributors to recent debate have not distinguished sufficiently between scientific classifications and the categories current in the English language of everyday life. In their review of the recent 'Anthropology and Genomics' conference, Simpson and Konrad point out how issues of race and policy arise in this dynamic field. ANTHROPOLOGY TODAY continues to offer a forum for topical debate on issues of public concern, and welcomes further contributions on these questions.

A solar collector is hoisted onto the roof of a Swedish house. In Sweden, the most common solar heating systems are those that supply hot water for both heating and general domestic hot water purposes. Contrary to popular belief, solar collectors are not dependent on a high air temperature, but produce heat throughout the year, whenever there is a clear sky. In her article, Annette Henning examines the actual and potential role of anthropology in energy studies. She reflects on her own experience of the trials of working as an anthropologist in the energy sector, where economists and technical expertise reign, and where production- and distribution-oriented approaches prevail. There is a great deal of resistance to anthropological contributions, in part because anthropologists have made so little effort to be heard in the public domain on this issue. In his editorial, Hal Wilhite makes the case for "energy anthropology". He argues that anthropologists have paid insufficient attention to one of the most urgent problems facing the world, namely our patterns of energy consumption and their economic and environmental consequences. Increasing consumerism in developing countries makes anthropological approaches indispensable, particularly in finding ways to moderate energy consumption and to help implement small-scale renewable energy initiatives. In his review of three of the latest books on vernacular architecture, Marcel Vellinga identifies architecture as a prominent cultural category and a major consumer of energy and resources, and thus a significant contributor to current environmental problems. Vellinga argues that anthropology should pay more attention to vernacular architecture as a locus of indigenous knowledge, to help the global community address the challenges of creating a sustainable built environment for all. ANTHROPOLOGY TODAY brings these contributions to your attention in the hope of stimulating discussion and promoting wider ethnographic research in areas of public concern. [source] Serious Games: Broadening Games Impact Beyond EntertainmentCOMPUTER GRAPHICS FORUM, Issue 3 2007Ben Sawyer Computer and videogames for many years has been an island of technology and design innovation largely left to itself as it morphed from a cottage business into a global media and software industry. While there have been pockets of derivative activity related to games and game technology only in the last half-dozen years has there been a real movement toward exploiting this industry in many new and exciting ways. Today the general use of games and game technologies for purposes beyond entertainment is collectively referred to as serious games. The Serious Games Initiative was formed in 2002 and since its inception has been among a number of critical efforts that has helped open up the world and many disciplines to the ideas and innovations that may be sourced from the commercial, independent, and academic game fields. This has been a person-by-person, project-by-project effort that not only has informed us about the potential of games but also in how you merge innovation and innovators from one discipline with those in another. In this talk we will explore the total gamut of the serious games field identifying past the obvious how games and game technologies are being applied to problems in a wide array of areas including healthcare, productivity, visualization, science, and of course training and education. Once a proper definition of serious games is established the talk will focus on the current state of the field as it relates to research and infrastructure issues that are needed to make the difference between seeing serious games take hold as a major new practice or having it devolve into another trend of the moment lost to history. [source] Are Points the Better Graphics Primitives?COMPUTER GRAPHICS FORUM, Issue 3 2001Markus Gross Since the early days of graphics the computer based representation of three-dimensional geometry has been one of the core research fields. Today, various sophisticated geometric modelling techniques including NURBS or implicit surfaces allow the creation of 3D graphics models with increasingly complex shape. In spite of these methods the triangle has survived over decades as the king of graphics primitives meeting the right balance between descriptive power and computational burden. As a consequence, today's consumer graphics hardware is heavily tailored for high performance triangle processing. In addition, a new generation of geometry processing methods including hierarchical representations, geometric filtering, or feature detection fosters the concept of triangle meshes for graphics modelling. Unlike triangles, points have amazingly been neglected as a graphics primitive. Although being included in APIs since many years, it is only recently that point samples experience a renaissance in computer graphics. Conceptually, points provide a mere discretization of geometry without explicit storage of topology. Thus, point samples reduce the representation to the essentials needed for rendering and enable us to generate highly optimized object representations. Although the loss of topology poses great challenges for graphics processing, the latest generation of algorithms features high performance rendering, point/pixel shading, anisotropic texture mapping, and advanced signal processing of point sampled geometry. This talk will give an overview of how recent research results in the processing of triangles and points are changing our traditional way of thinking of surface representations in computer graphics - and will discuss the question: Are Points the Better Graphics Primitives? [source] High-precision measurement of internuclear distances using solid-state NMRCONCEPTS IN MAGNETIC RESONANCE, Issue 1 2008Jae-Seung Lee Abstract Today, nuclear magnetic resonance (NMR) is among the most efficient tools in structural studies. Measurement of interatomic distances is the most common way of determining high-resolution structures of molecules using NMR techniques. In this article, we describe NMR techniques for static powder samples, based on a two-dimensional single-echo scheme, enhanced with adiabatic cross-polarization. They can significantly increase the accuracy of measuring internuclear distances and turn NMR into a high-precision crystallographic technique, complementing the X-ray, and neutron-scattering methods.

[source] Simulation of resource synchronization in a dynamic real-time distributed computing environmentCONCURRENCY AND COMPUTATION: PRACTICE & EXPERIENCE, Issue 14 2004Chen Zhang Abstract Today, more and more distributed computer applications are being modeled and constructed using real-time principles and concepts. In 1989, the Object Management Group (OMG) formed a Real-Time Special Interest Group (RT SIG) with the goal of extending the Common Object Request Broker Architecture (CORBA) standard to include real-time specifications. This group's most recent efforts have focused on the requirements of dynamic distributed real-time systems. One open problem in this area is resource access synchronization for tasks employing dynamic priority scheduling. This paper presents two resource synchronization protocols that the authors have developed which meet the requirements of dynamic distributed real-time systems as specified by Dynamic Scheduling Real-Time CORBA (DSRT CORBA). The proposed protocols can be applied to both Earliest Deadline First (EDF) and Least Laxity First (LLF) dynamic scheduling algorithms, allow distributed nested critical sections, and avoid unnecessary runtime overhead. In order to evaluate the performance of the proposed protocols, we analyzed each protocol's schedulability. Since the schedulability of the system is affected by numerous system configuration parameters, we have designed simulation experiments to isolate and illustrate the impact of each individual system parameter. Simulation experiments show the proposed protocols have better performance than one would realize by applying a schema that utilizes dynamic priority ceiling update. Copyright © 2004 John Wiley & Sons, Ltd. [source] Forest Stand Dynamics and Livestock Grazing in Historical ContextCONSERVATION BIOLOGY, Issue 5 2005MICHAEL M. BORMAN clima; incendio forestal; pastoreo histórico; pino ponderosa; supresión de fuego Abstract:,Livestock grazing has been implicated as a cause of the unhealthy condition of ponderosa pine forest stands in the western United States. An evaluation of livestock grazing impacts on natural resources requires an understanding of the context in which grazing occurred. Context should include timing of grazing, duration of grazing, intensity of grazing, and species of grazing animal. Historical context, when and under what circumstances grazing occurred, is also an important consideration. Many of the dense ponderosa pine forests and less-than-desirable forest health conditions of today originated in the early 1900s. Contributing to that condition was a convergence of fire, climate, and grazing factors that were unique to that time. During that time period, substantially fewer low-intensity ground fires (those that thinned dense stands of younger trees) were the result of reduced fine fuels (grazing), a substantial reduction in fires initiated by Native Americans, and effective fire-suppression programs. Especially favorable climate years for tree reproduction occurred during the early 1900s. Exceptionally heavy, unregulated, unmanaged grazing by very large numbers of horses, cattle, and sheep during the late nineteenth and early twentieth centuries occurred in most of the U.S. West and beginning earlier in portions of the Southwest. Today, livestock numbers on public lands are substantially lower than they were during this time and grazing is generally managed. Grazing then and grazing now are not the same. Resumen:,El pastoreo de ganado ha sido implicado como una causa de la mala salud de los bosques de pino ponderosa en el occidente de Estados Unidos. La evaluación de los impactos del pastoreo sobre los recursos naturales requiere de conocimiento del contexto en que ocurrió el pastoreo. El contexto debe incluir al período de ocurrencia, la duración y la intensidad del pastoreo, así como la especie de animal que pastoreó. El contexto histórico, cuando y bajo que circunstancias ocurrió el pastoreo, también es una consideración importante. Muchos de los bosques densos de pino ponderosa y de las condiciones, menos que deseables, de salud de los bosques actuales se originaron al principio del siglo pasado. Contribuyó a esa condición una convergencia de factores, fuego, clima y pastoreo, que fueron únicos en ese tiempo. Durante ese período, hubo sustancialmente menos incendios superficiales de baja intensidad (que afectaron a grupos densos de árboles más jóvenes) como resultado de la reducción de combustibles finos (pastoreo), una reducción sustancial en los incendios iniciados por Americanos Nativos y programas efectivos de supresión de incendios. Al inicio del siglo pasado hubo años con clima especialmente favorable para la reproducción de árboles. Al final del siglo diecinueve y comienzo del veinte hubo pastoreo no regulado ni manejado, excepcionalmente intensivo, por una gran cantidad de caballos, reses y ovejas en la mayor parte del oeste de E.U.A. y aun antes en porciones del suroeste. En la actualidad, el número de semovientes en terrenos públicos es sustancialmente menor al de ese tiempo, y el pastoreo generalmente es manejado. El pastoreo entonces y el pastoreo ahora no son lo mismo. [source] RESTRUCTURING U.S. FEDERAL FINANCIAL REGULATIONCONTEMPORARY ECONOMIC POLICY, Issue 3 2007ROSE M. KUSHMEIDER Despite changes over the past 70 yr, the U.S. federal financial regulatory system remains rooted in the reforms of the 1930s. The institutions governed by this system have, nevertheless, continued to evolve. Today, regulation of large, multiproduct, internationally active financial organizations poses challenges for a system designed largely to regulate smaller, distinct, locally based organizations. Reform of the regulatory system, however, is not an easy task,complex issues regarding deposit insurance, the role of the central bank, and the dual banking system must be addressed. In the absence of a crisis, however, regulatory restructuring will not likely generate much political interest. (JEL G28) [source] Equilibrium and growth shapes of crystals: how do they differ and why should we care?CRYSTAL RESEARCH AND TECHNOLOGY, Issue 4-5 2005Robert F. SekerkaArticle first published online: 15 MAR 200 Abstract Since the death of Prof. Dr. Jan Czochralski nearly 50 years ago, crystals grown by the Czochralski method have increased remarkably in size and perfection, resulting today in the industrial production of silicon crystals about 30 cm in diameter and two meters in length. The Czochralski method is of great technological and economic importance for semiconductors and optical crystals. Over this same time period, there have been equally dramatic improvements in our theoretical understanding of crystal growth morphology. Today we can compute complex crystal growth shapes from robust models that reproduce most of the features and phenomena observed experimentally. We should care about this because it is likely to result in the development of powerful and economical design tools to enable future progress. Crystal growth morphology results from an interplay of crystallographic anisotropy and growth kinetics by means of interfacial processes and long-range transport. The equilibrium shape of a crystal results from minimizing its anisotropic surface free energy under the constraint of constant volume; it is given by the classical Wulff construction but can also be represented by an analytical formula based on the ,-vector formalism of Hoffman and Cahn. We now have analytic criteria for missing orientations (sharp corners or edges) on the equilibrium shape, both in two (classical) and three (new) dimensions. Crystals that grow under the control of interfacial kinetic processes tend asymptotically toward a "kinetic Wulff shape", the analogue of the Wulff shape, except it is based on the anisotropic interfacial kinetic coefficient. If it were not for long range transport, crystals would presumably nucleate with their equilibrium shape and then evolve toward their "kinetic Wulff shape". Allowing for long range transport leads to morphological instabilities on the scale of the geometric mean of a transport length (typically a diffusivity divided by the growth speed) and a capillary length (of the order of atomic dimensions). Resulting crystal growth shapes can be cellular or dendritic, but can also exhibit corners and facets related to the underlying crystallographic anisotropy. Within the last decade, powerful phase field models, based on a diffuse interface, have been used to treat simultaneously all of the above phenomena. Computed morphologies can exhibit cells, dendrites and facets, and the geometry of isotherms and isoconcentrates can also be determined. Results of such computations are illustrated in both two and three dimensions. (© 2005 WILEY-VCH Verlag GmbH & Co.

In the United States, children's museums represent one of the youngest and fastest growing cultural sectors. Our field was founded in 1899 with the opening of the Brooklyn Children's Museum. Anna Billings Gallup, an influential curator and director at the museum from 1902 to 1937, spoke widely about the value of bringing the child into the forefront of museum activities. In the United States, the field grew slowly but steadily to four children's museums in 1925 and to approximately 38 by 1975. In the last three decades, sparked by the groundbreaking work of Michael Spock at the Boston Children's Museum, the field has been energized by an extraordinary boom in new and expanding children's museums. Today there are approximately 350 worldwide. [source] Relationship of Student Undergraduate Achievement and Personality Characteristics in a Total Web-Based Environment: An Empirical StudyDECISION SCIENCES JOURNAL OF INNOVATIVE EDUCATION, Issue 2 2005Marc J. Schniederjans ABSTRACT Web-based education is a popular format for the delivery of college courses. Research has shown that it may not be the best form of education for all students. Today, many students (and student advisors) face a choice in course delivery format (i.e., Web-based or more traditional classroom courses). This research study examines the relationship between student personality characteristics and their achievement scores as a means of identifying predictors of academic success in an undergraduate business program using Web-based education. The results of the study show that four basic personality characteristics are highly correlated to student achievement in Web-based courses. Use of these personality characteristics as variables in a regression model is shown to be a highly accurate predictive tool to aid students in the decision as to whether to take a particular Web-based course format or a more traditional classroom course.

Consequently, the use of bone substitutes has increased. Today, a substantial number of biomaterials are available on the market, but only a few are well documented. The user should be aware that these biomaterials have different properties: resorbable or non-resorbable, time of resorption and resorption mechanism. The purpose of this review is to describe the function of various bone substitutes and indications for their use in reconstructive implant surgery and to give an overview of the current situation. [source] Medical treatment of hirsutismDERMATOLOGIC THERAPY, Issue 5 2008Ulrike Blume-Peytavi ABSTRACT:, Hirsutism is usually the result of an underlying adrenal, ovarian, or central endocrine abnormality mainly due to polycystic ovary syndrome but may also be idiopathic or drug induced. The aim of medical treatment of hirsutism is to rectify any causal hormonal balance, slow down or stop excessive hair growth, and improve the aesthetic appearance of hirsutism, thereby positively affecting the patient's quality of life. Today, for the majority of women, a monotherapy with oral contraceptives that have antiandrogenic activity is recommended as a first-line treatment for hirsutism. Combining an oral contraceptive pill with an antiandrogen is recommended if clinical improvement of hirsutism is insufficient after 6,9 months' monotherapy. In women who present with hirsutism, hyperandrogenism, and insulin resistance, insulin sensitizers are effective for the hirsutism as well as the hyperinsulinemia, hyperandrogenism, and infertility but there is no convincing evidence that they are effective for hirsutism alone. Topical eflornithine is a medical therapy that can be a useful adjuvant for hirsutism when used in conjunction with systemic medications or with laser/photoepilation. [source] Soft tissue augmentation 2006: filler fantasyDERMATOLOGIC THERAPY, Issue 3 2006Arnold William Klein ABSTRACT:, As an increasing number of patients seek esthetic improvement through minimally invasive procedures, interest in soft tissue augmentation and filling agents is at an all-time high. One reason for this interest is the availability of botulinum toxin type A, which works superbly in the upper face. The rejuvenation of the upper face has created much interest in injectable filling agents and implant techniques that work equally well in the restoration of the lower face. One of the central tenets of soft tissue augmentation is the concept of the three-dimensional face. The youthful face has a soft, full appearance, as opposed to the flat, pulled, two-dimensional look often achieved by more traditional surgical approaches. Injectable filling agents can augment and even at times, replace pulling. Additionally, with the lip as the focal center of the lower face, subtle lip enhancement is here to stay, and is in fact, the number one indication for injectable fillers. Moreover, minimally invasive soft tissue augmentation offers cosmetic enhancement without the cost and recovery time associated with more invasive procedures. As more and more physicians take interest in minimally invasive surgery, courses in cosmetic surgery techniques are becoming increasingly popular at the medical meetings of many specialties. Today, physicians have a much larger armamentarium of techniques and materials with which to improve facial contours, ameliorate wrinkles, and provide esthetic rejuvenation to the face. For a substance or device to be amenable for soft tissue augmentation in the medical community, it must meet certain criteria. It must have both a high "use" potential, producing cosmetically pleasing results with a minimum undesirable reactions, and have a low abuse potential in that widespread or incorrect or indiscriminate use would not result in significant morbidity. It must be nonteratogenic, noncarcinogenic, and nonmigratory. In addition, the agent must provide predictable, persistent correction through reproducible implantation techniques. Finally, the substance, agent or device must be approved by the U.S. Food and Drug Administration, which assures purity, safety, and accessibility, as well as much-needed information regarding use. Having a thorough understanding of the filling agents available, their indications and contraindications, as well as having thorough knowledge of implant technique are vital in providing the patient with an esthetically pleasing result. [source] The stratum corneum: structure and function in health and diseaseDERMATOLOGIC THERAPY, Issue 2004Clive R. Harding ABSTRACT:, Our understanding of the formation, structure, composition, and maturation of the stratum corneum (SC) has progressed enormously over the past 30 years. Today, there is a growing realization that this structure, while faithfully providing a truly magnificent barrier to water loss, is a unique, intricate biosensor that responds to environmental challenges and surface trauma by initiating a series of biologic processes which rapidly seek to repair the damage and restore barrier homeostasis. The detailed ultrastructural, biochemical, and molecular dissection of the classic "bricks and mortar" model of the SC has provided insights into the basis of dry, scaly skin disorders that range from the cosmetic problems of winter xerosis to severe conditions such as psoriasis. With this knowledge comes the promise of increasingly functional topical therapies. [source] Gene transfer into chicken embryos as an effective system of analysis in developmental biologyDEVELOPMENT GROWTH & DIFFERENTIATION, Issue 3 2000Sadao Yasugi Chicken embryos have been used as a model animal in developmental biology since the time of comparative and experimental embryology. Recent application of gene transfer techniques to the chicken embryo increases their value as an experimental animal. Today, gene transfer into chicken cells is performed by three major systems, lipofection, electroporation and the virus-mediated method. Each system has its own features and applicability. In this overview and the associated four minireviews, the methods and application of each system will be presented. [source] Therapeutic targets in the management of Type 1 diabetesDIABETES/METABOLISM: RESEARCH AND REVIEWS, Issue S1 2002P. D. Home Abstract For historical reasons, diabetes has long been linked with blood and urine glucose control, partly because these were clearly linked to acute symptoms, and partly because glucose became measurable around 200 years ago. Today it is recognized that there is far more to diabetes than simply monitoring symptoms and blood glucose. Intensive management has an impact on the quality of life. Late complications have their own risk factors and markers. Monitoring and early detection of these risk factors and markers can lead to changes in treatment before tissue damage is too severe. Accordingly, professionals now find themselves monitoring a range of adverse outcomes, markers for adverse outcomes, risk factors and risk markers for microvascular and arterial disease, acute complications of therapy, and the care structures needed to deliver this. Adverse outcomes lend themselves to targets for complication control in populations, and markers of adverse outcomes (such as retinopathy and raised albumin excretion rate) in treatment cohorts. Surveillance systems will have targets for yearly recall and review of early complications. Metabolic (surrogate) outcomes can be monitored in individual patients, but monitoring is only of value in so far as it guides interventions, and this requires comparison to some intervention level or absolute target. Even for blood glucose control this is not easy, for conventional measures such as glycated haemoglobin have their own problems, and more modern approaches such as post-prandial glucose levels are controversial and less convenient to measure. In many people with type 1 diabetes targets for blood pressure, LDL cholesterol, and serum triglycerides will also be appropriate, and need to be part of any protocol of management. Copyright © 2002 John Wiley & Sons, Ltd. [source] Animal models of diabetes mellitusDIABETIC MEDICINE, Issue 4 2005D. A. Rees Abstract Animal models have been used extensively in diabetes research. Early studies used pancreatectomised dogs to confirm the central role of the pancreas in glucose homeostasis, culminating in the discovery and purification of insulin. Today, animal experimentation is contentious and subject to legal and ethical restrictions that vary throughout the world. Most experiments are carried out on rodents, although some studies are still performed on larger animals. Several toxins, including streptozotocin and alloxan, induce hyperglycaemia in rats and mice. Selective inbreeding has produced several strains of animal that are considered reasonable models of Type 1 diabetes, Type 2 diabetes and related phenotypes such as obesity and insulin resistance. Apart from their use in studying the pathogenesis of the disease and its complications, all new treatments for diabetes, including islet cell transplantation and preventative strategies, are initially investigated in animals. In recent years, molecular biological techniques have produced a large number of new animal models for the study of diabetes, including knock-in, generalized knock-out and tissue-specific knockout mice. [source] Ecological Theology: Roots in Tradition, Liturgical and Ethical Practice for TodayDIALOG, Issue 3 2003Rosemary Radford Ruether Abstract Often it is claimed that themes occasionally present in Christianity such as anthropocentrism, ecological alienation, and redemption as a world-escaping disembodied immortality, translated directly into large-scale abuse of nature and subsequent ecological crisis. Such a view is too simplistic, however. Instead the present environmental and ecological crisis may be primarily traced to cultural, economic, and technological developments of the last 500 years. Indeed, within Christian monasticism, ecofeminism, covenantal ethics, and cosmic christology, one finds ample resources for the transformation of human attitudes towards nature and a brighter ecological future.

This makes confirmation ministry as discipleship training most important in our churches. This article explores the confirmation ministry of Lord of Life Lutheran Church in Depew, NY, and critically analyzes the methodology,4 turnings, 6 disciplines, and 19 assets,behind the ministry. This methodology has been developed from researchers such as Jean Piaget, James Fowler, Duffy Robins, and researchers at the Search Institute. [source] Confirmation Ministry in the Batak ChurchDIALOG, Issue 3 2002Binsar Nainggolan Historically, confirmation ministry among Batak's took the form of missionaries presenting the Christian religion in an apologetic and persuasive tone, in an effort to ready Batak converts for Baptism. Today, confirmation ministry among Batak Christians is understood as a fleshing out of what it means to be baptized into the church community. This article explores the method and aims of the confirmation rite and ministry among Batak Christians. [source] Land-cover and land-use change and its contribution to the large-scale organization of Puerto Rico's bird assemblagesDIVERSITY AND DISTRIBUTIONS, Issue 1 2008Miguel A. Acevedo ABSTRACT Global biodiversity is changing rapidly driven by human alteration of habitat, and nowhere this is more dramatic than in insular habitats. Yet land-cover change is a complex phenomenon that not only involves habitat destruction but also forest recovery over different time scales. Therefore, we might expect species to respond in diverse ways with likely consequences for the reorganization of regional assemblages. These changes, however, may be different in tropical islands because of their low species richness, generalist habits and high proportion of endemics. Here, we focus on the island of Puerto Rico and ask how island-wide changes in land cover and land use has influenced the large-scale organization of bird assemblages. To address this question, we combined in a Geographical Information System (GIS) the first 6 years (1997,2002) of the Puerto Rican Breeding Bird Survey (PR-BBS) with land-cover and land-use data extracted from a published digital map derived from the classification of Landsat images. A Non-metric Multidimensional Scaling (NMS) ordination based on the composition and abundance of birds, and percentage land-use types showed that land use followed by climate could explain most of the variation observed among routes in terms of species composition and abundance. Moreover, endemic and exotic species were widely distributed throughout the island, but the proportion of endemic species is higher in closed forests while exotic species are more abundant in open habitats. However, historical accounts from the early 1900s indicate that endemic species were distributed across the entire island. Today, most of the land cover transformation in Puerto Rico occurs in the lowlands which may explain the high abundance of endemic species in cloud forests and the high abundance of exotic species in open habitats in the lowlands.
