New Breed (new + breed)
Selected AbstractsA survey of mobile and wireless technologies for augmented reality systemsCOMPUTER ANIMATION AND VIRTUAL WORLDS (PREV: JNL OF VISUALISATION & COMPUTER ANIMATION), Issue 1 2008George Papagiannakis Abstract Recent advances in hardware and software for mobile computing have enabled a new breed of mobile augmented reality (AR) systems and applications. A new breed of computing called ,augmented ubiquitous computing' has resulted from the convergence of wearable computing, wireless networking, and mobile AR interfaces. In this paper, we provide a survey of different mobile and wireless technologies and how they have impact AR. Our goal is to place them into different categories so that it becomes easier to understand the state of art and to help identify new directions of research. Copyright © 2008 John Wiley & Sons, Ltd. [source] A beginner's guide to radiation damageJOURNAL OF SYNCHROTRON RADIATION, Issue 2 2009James M. Holton Many advances in the understanding of radiation damage to protein crystals, particularly at cryogenic temperatures, have been made in recent years, but with this comes an expanding literature, and, to the new breed of protein crystallographer who is not really interested in X-ray physics or radiation chemistry but just wants to solve a biologically relevant structure, the technical nature and breadth of this literature can be daunting. The purpose of this paper is to serve as a rough guide to radiation damage issues, and to provide references to the more exacting and detailed work. No attempt has been made to report precise numbers (a factor of two is considered satisfactory), and, since there are aspects of radiation damage that are demonstrably unpredictable, the `worst case scenario' as well as the `average crystal' are discussed in terms of the practicalities of data collection. [source] Ethernet aggregation and core network models for effcient and reliable IPTV servicesBELL LABS TECHNICAL JOURNAL, Issue 1 2007Christian Hermsmeyer With the growing interest on wireline network architectures for residential triple-play and business Ethernet services there is a renewed demand for efficient and reliable packet-based transport capabilities between the content providers and the end users. Voice and data traffic carried over a variety of access technologies is collected via technology-specific access networks (e.g., digital subscriber line [xDSL], passive optical network [xPON], and wireless fidelity [WiFi]). Metro and core networks need to aggregate the various user flows from different access network nodes and provide scalable and cost-effective distribution of various flow types (e.g., Internet access, voice, video on demand, and broadcast TV services) to the relevant service access points. Varying quality of service and resiliency requirements for these services are being reflected in a new breed of converged Ethernet and optical network elements with capabilities to interwork the bearer-planes of these two networking technologies seamlessly. Network elements based on Ethernet/Optical converged technology are able to select the most fitting mechanisms from each networking technology to meet the transport requirements for each individual service demand better while providing significantly enhanced implementation and operational efficiencies. This paper discusses network architecture models and network elements addressing these goals. © 2007 Alcatel-Lucent. [source] The times they are a changinJOURNAL OF NURSING MANAGEMENT, Issue 5 2009Cert Ed, MIKE THOMAS PhD Aim, A discussion paper outlining the potential for a multi-qualified health practitioner who has undertaken a programme of study incorporating the strengths of the specialist nurse with other professional routes. Background and rationale, The concept and the context of ,nursing' is wide and generalized across the healthcare spectrum with a huge number of practitioners in separate branches, specialities and sub-specialities. As a profession, nursing consists of different groups in alliance with each other. How different is the work of the mental health forensic expert from an acute interventionalist, or a nurse therapist, from a clinical expert in neurological deterioration? The alliance holds because of the way nurses are educated and culturalized into the profession, and the influence of the statutory bodies and the context of a historical nationalized health system. This paper discusses the potential for a new type of healthcare professional, one which pushes the intra- and inter-professional agenda towards multi-qualified staff who would be able to work across current care boundaries and be more flexible regarding future care delivery. In September 2003, the Nursing and Midwifery Council stated that there were ,more than 656 000 practitioners' on its register and proposed that from April 2004, there were new entry descriptors. Identifying such large numbers of practitioners across a wide range of specialities brings several areas of the profession into question. Above all else, it highlights how nursing has fought and gained recognition for specialisms and that through this, it may be argued client groups receive the best possible ,fit' for their needs, wants and demands. However, it also highlights deficits in certain disciplines of care, for example, in mental health and learning disabilities. We argue that a practitioner holding different professional qualifications would be in a position to provide a more holistic service to the client. Is there then a gap for a ,new breed' of practitioner; ,a hybrid' that can achieve a balanced care provision to reduce the stress of multiple visits and multiple explanations? Methods, Review of the literature but essentially informed by the authors personal vision relating to the future of health practitioner education. Implications for nursing management, This article is of significance for nurse managers as the future workforce and skill mix of both acute and community settings will be strongly influenced by the initial preregistration nurse education. [source] Pacific ,Babes': issues in the origins and dispersal of Pacific pigs and the potential of mitochondrial DNA analysis,INTERNATIONAL JOURNAL OF OSTEOARCHAEOLOGY, Issue 1-2 2001Melinda S. Allen Abstract We explore potential sources of genetic variation in Pacific pigs over the duration of their commensal relationships with Pacific people. Three time periods are identified as critical to understanding the history of pigs in the Pacific region: (1) the late Pleistocene,early Holocene following from human movement into Near Oceania; (2) with Lapita colonization of Remote Oceania beginning ca. 3000 bp, and (3) in Polynesia, shortly after sustained Euro-American contact (ca. late 1700s) when several new breeds were introduced into the region. This paper highlights the important role mitochondrial DNA (mtDNA) work can play in detailing the origins, directions, and frequency of pig transfers, and by extension, the movements of their human carriers. Our preliminary molecular studies identify a hypervariable region of mtDNA in the genus Sus, rendering it an ideal taxon for detailed study of the issues we raise herein.

[source] Global geographies of innovation diffusion: the case of the Australian cattle industryTHE GEOGRAPHICAL JOURNAL, Issue 1 2010MATTHEW TONTS The geographies and histories of the introduction of cattle breeds to Australia in the period since white settlement are documented as an example of the diffusion of agricultural innovations. Three phases of development are identified: a colonial expansion phase from the late eighteenth to the early twentieth century during which a number of primarily British cattle breeds were imported by the colonial settlers; an innovative phase in the mid twentieth century when both governments and private interests sought to produce or import new breeds deemed to be better adapted to Australian environments; and a multifunctional phase in recent decades. In this final phase, government deregulation and new technologies, such as the long distance transport of genetic packages, have facilitated the importation and development of many new cattle breeds in Australia. While this has produced a significant rise in the total number of breeds represented nationally, many recent and historic breeds currently exhibit extremely small numbers and a few generally well-established breeds such as Holstein, Hereford and Angus still dominate the national herd. This study of changing breed types and introductions provides some evidence of post-productivism and of a multifunctional transition in that several cattle breeds favoured by hobby farmers and boutique breeders are now represented, but the aggregate numbers for these breeds remain small and the numbers for several of the traditional (or colonial) breeds are currently in decline. Overall, it is apparent that Australia's cattle industry retains a strongly productivist ethos and that, particularly given the country's very great environmental variation, its levels of breed diversity remain low. [source] Use of linked loci as individuals or haplotypes for marker-assisted breed assignmentANIMAL GENETICS, Issue 1 2008A. Stella Summary The objective of this study was to use simulation to evaluate the benefits of considering haplotypes of loci when linked single nucleotide polymorphisms are used for breed assignment. Three breeds of 10 000 females each were simulated under eight scenarios that differed according to the number of generations separating the breeds, size of breed founder populations and recombination rate between linked loci. Molecular genotypes consisted of 20 groups of three linked loci each. Breed assignment was performed in the final generation and was based on the frequency method. Haplotypes were reconstructed using the expectation,maximization algorithm. Accuracy of breed assignment was based on the frequency of correct breed assignment. Assignment accuracy increased as more genotypes (loci or haplotypes) were considered and more animals were used to estimate genotypic frequencies within breed. For most scenarios, use of haplotypes yielded equal or greater accuracies than when loci were considered independent. The advantage of haplotypes tended to increase as linkage disequilibrium between adjacent loci increased. The greatest advantage for using haplotypes was observed when recombination rate was low (0.001), breeds were separated by few generations (100), and a relatively large number of founder animals (110) was used to form new breeds. In this situation, 90% accuracy of breed assignment was achieved using nine to 14 haplotypes (i.e. 27,42 loci) depending on breed, vs. 39,57 individual loci. [source] | ||||||||||
