Recently, Y chromosome markers have begun to be used to study Native American origins. Available data have been interpreted as indicating that the colonizers of the New World carried a single founder haplotype. However, these early studies have been based on a few, mostly complex polymorphisms of insufficient resolution to determine whether observed diversity stems from admixture or diversity among the colonizers. Because the interpretation of Y chromosomal variation in the New World depends on founding diversity, it is important to develop marker systems with finer resolution. Here we evaluate the hypothesis of a single-founder Y haplotype for Amerinds by using 11 Y-specific markers in five Colombian Amerind populations. Two of these markers (DYS271, DYS287) are reliable indicators of admixture and detected three non-Amerind chromosomes in our sample. Two other markers (DYS199, M19) are single-nucleotide polymorphisms mostly restricted to Native Americans. The relatedness of chromosomes defined by these two markers was evaluated by constructing haplotypes with seven microsatellite loci (DYS388 to 394). The microsatellite backgrounds found on the two haplogroups defined by marker DYS199 demonstrate the existence of at least two Amerind founder haplotypes, one of them (carrying allele DYS199 T) largely restricted to Native Americans. The estimated age and distribution of these haplogroups places them among the founders of the New World.

More than 30 years ago, Brambell published the hypothesis bearing his name [Brambell, F. W. R., Hemmings, W. A. & Morris, 1. C. (1964) Nature (London) 203, 1352-1355] that remains as the cornerstone for thinking on IgG catabolism. To explain the long survival of IgG relative to other plasma proteins and its pattern of increased fractional catabolism with high concentrations of IgG, Brambell postulated specific IgG "protection receptors" (FcRp) that would bind IgG in pinocytic vacuoles and redirect its transport to the circulation; when the FcRp was saturated, the excess unbound IgG then would pass to unrestricted lysosomal catabolism. Brambell subsequently postulated the neonatal gut transport receptor (FcRn) and showed its similar saturable character. FcRn was recently cloned but FcRp has not been identified. Using a genetic knockout that disrupts the FcRn and intestinal IgG transport, we show that this lesion also disrupts the IgG protection receptor, supporting the identity of these two receptors. IgG catabolism was 10-fold faster and IgG levels were correspondingly lower in mutant than in wild-type mice, whereas IgA was the same between groups, demonstrating the specific effects on the IgG system. Disruption of the FcRp in the mutant mice was also shown to abrogate the classical pattern of decreased IgG survival with higher IgC concentration. Finally, studies in normal mice with monomeric antigen-antibody complexes showed differential catabolism in which antigen dissociates in the endosome and passes to the lysosome, whereas the associated antibody is returned to circulation; in mutant mice, differential catabolism was lost and the whole complex cleared at the same accelerated rate as albumin, showing the central role of the FcRp to the differential catabolism mechanism. Thus, the same receptor protein that mediates the function of the FcRn transiently in the neonate is shown to have its functionally dominant expression as the FcRp throughout life, resolving a longstanding mystery of the identity of the receptor for the protection of IgG. This result also identifies an important new member of the class of recycling surface receptors and enables the design of protein adaptations to exploit this mechanism to improve survivals of other therapeutic proteins in vivo.

Bowerbirds (Ptilonorhynchidae) have previously been considered to be confined to the Australo-Papuan continental plate. We provide molecular evidence that the extinct New Zealand Piopio Turnagra capensis is, in fact, a bowerbird. Such a finding is surprising on biogeographical grounds. However, recent molecular evidence on the relationships of the New Zealand moas and kiwis with the Australo-Papuan flightless birds suggests the need for a reassessment of current views on the origins of New Zealand's fauna.

Information obtained from studies of developmental and cellular processes in lower organisms is beginning to make significant contributions to the understanding of the pathogenesis of human birth defects, and it is now becoming possible to treat birth defects as inborn errors of development. Mutations in genes for transcription factors, receptors, cell adhesion molecules, intercellular junctions, molecules involved in signal transduction, growth factors, structural proteins, enzymes, and transporters have been identified in genetically caused human malformations and dysplasias. The identification of these mutations and the analysis of their developmental effects have been greatly facilitated by the existence of natural or engineered models in the mouse and even of related mutations in Drosophila, and in some instances a remarkable conservation of function in development has been observed, even between widely separated species.

In the first wave, behaviorists questioned the conventional wisdom that inner experience was relevant to understanding human behavior. In the 1970s, cognitive-behavioral theories emphasized the importance of the cognitive element, not just the environment, in explaining and modifying behavior. The third wave is drawn from advances in basic and applied behavior analysis of language, Eastern mystical traditions, and less empirically oriented therapeutic approaches. Examples include Acceptance and Commitment Therapy (ACT), Dialectical Behavior Therapy (DBT), Functional Analytic Psychotherapy (FAP), and Mindfulness Based Cognitive Therapy (IBCT). This study reports a survey of clinicians and non-clinicians who self-identify with second or third wave approaches, and a group of undergraduate psychology students intended to represent a layperson or folk psychological approach. Their preferences, in the context of 10 clinical vignettes, among 5 different therapeutic responses or interventions that included "ACT-like," "cognitive," and commonsense or "neutral" options were measured. Third wave-oriented respondents exhibited more consistency than others in their preference for interventions that match their self-identified theoretical orientation, however the author suggests that construction of the vignettes may have influenced this result.

Onboarding is an important aspect of the employment process that has been often ignored. Overlooked onboarding results in high turnover costs, totaling up to 30 to 50 percent of an employee's first-year pay. To decrease this turnover and its associated high costs, this paper proposes the implementation of a highly strategic onboarding process. This process has a strategic focus, SMART goals, integrates multiple offices and people, and addresses all new employee needs with two considerations, generational and technological advances. An employee stays continuously and actively engaged, with vested interest in success, maximizing engagement and retention. The process focuses on constant and continuous feedback from all stakeholders. The project is a practical guide for implementing a new strategically focused onboarding process.

Introduction: Current physical activity levels among children and youth are alarmingly low; a mere 7% of children and youth are meeting the Canadian Physical Activity Guidelines (Colley et al., 2011), which means that the vast majority of this population is at risk of developing major health problems in adulthood (Janssen & Leblanc, 2010). These high inactivity rates may be related to suboptimal experiences in sport and physical activity stemming from a lack of competence and confidence (Lubans, Morgan, Cliff, Barnett, & Okely, 2010). Developing a foundation of physical literacy can encourage and maintain lifelong physical activity, yet this does not always occur naturally as a part of human growth (Hardman, 2011). An ideal setting to foster the growth and development of physical literacy is physical education class. Physical education class can offer all children and youth an equal opportunity to learn and practice the skills needed to be active for life (Hardman, 2011). Elementary school teachers are responsible for delivering the physical education curriculum, and it is important to understand their will and capacity as the implementing agents of physical literacy development curriculum (McLaughlin, 1987). Purpose: The purpose of this study was to explore the physical literacy component of the 2015 Ontario Health and Physical Education curriculum policy through the eyes of key informants, and to explore the resources available for the implementation of this new policy. Methods: Qualitative interviews were conducted with seven key informants of the curriculum policy development, including two teachers. In tandem with the interviews, a resource inventory and curriculum review were conducted to assess the content and availability of physical literacy resources. All data were analyzed through the lens of Hogwood and Gunn’s (1984) 10 preconditions for policy implementation. Results: Participants discussed how implementation is affected by: accountability, external capacity, internal capacity, awareness and understanding of physical literacy, implementation expertise, and policy climate. Discussion: Participants voiced similar opinions on most issues, and the overall lack of attention given to physical education programs in schools will continue to be a major dilemma when trying to combat such high physical inactivity levels.

This CEPS Policy Brief reviews key aspects of the new financial paradigm in a transatlantic perspective, focusing on the general approach in EU and US legislation in response to the financial crisis and the G-20 commitments and specifically as regards the extraterritorial implications. Following discussion of the institutional setting, conclusions are offered on what these changes mean in the context of the recently proposed Transatlantic Trade and Investment Partnership. In comparing the EU and the US efforts in re-engineering their regulatory regimes in response to the financial crisis, the paper finds, with the notable exception of the banking union, serious grounds for concern that the outcome may be an even more fragmented European financial market, access to which for third-country institutions is highly problematic.

The Irish Presidency of the Council of the EU (January-June 2013) faced numerous challenges, not least of which was to negotiate the financial framework for the period 2014-2020 and the reform of the Common Agricultural Policy with the European Parliament, as well as the pressure to advance the banking agenda. Moreover, the fact that it was the start of a new Trio Presidency, the small size of the Irish administration and its fragile financial situation gave rise to some doubts as to how much it could achieve. Nevertheless, this post mortem on the Irish presidency finds that the Irish government approached the task with realism and optimism, a firm focus on results and the strong conviction that a good performance would enhance its reputation at home and in the EU. It is now for Lithuania and subsequently Greece, in the first half of 2014, to continue to tackle the remaining formidable challenges.

Introduction. Regional government in contemporary western Europe corresponds to a type of society and economy variously labeled "post-industrial", "post-bourgeois" or merely "the New Europe."l This New Europe evolved historically from the interconnected strands of capitalism; industrialism and pluralistic democracy. It resembles in many respects the type of economy and society familiar to us in North America. Regional government in such a society is thus merely an adaptation on the scale of half a continent of forms of social and economic organization which evolved historically at the national level. Regional government in the New Europe is the institutional and political recognition that societies have changed dramatically since 1945, so dramatically that they cannot be adequately described in the doctrines and ideologies made familiar by nineteenth and early twentieth century political thought. Hence the New Europe and its regional government is the future of that part of history which has also been aptly described as "the end of ideology."

This short contribution outlines the renewed constitutional framework in which the “European Neighbourhood Policy” (ENP) is to be integrated and further developed (1.) and briefly discusses its possible implications for the finalité of the neighbourhood relationship in general and of the ENP more specifically (2.). This constitutional perspective reveals three – already well-known – conceptual problems of the ENP (3.).

Nationalism remains central to politics in and among the new nation-states. Far from »solving« the region's national question, the most recent reconfiguration of political space – the replacement of the Soviet Union, Yugoslavia, and Czechoslovakia by some twenty would-be nation-states – only recast it in a new form. It is this new phase and form of the national question that I explore in this paper. I begin by outlining a particular relational configuration – the triadic relational nexus between national minorities, nationalizing states, and external national homelands – that is central to the national question in post-Soviet Eurasia. In the second, and most substantial, section of the paper, I argue that each of the »elements« in this relational nexus – minority, nationalizing state, and homeland – should itself be understood in dynamic and relational terms, not as a fixed, given, or analytically irreducible entity but as a field of differentiated positions and an arena of struggles among competing »stances.« In a brief concluding section, I return to the relational nexus as a whole, underscoring the dynamically interactive quality of the triadic interplay.

This Policy Brief describes and discusses the proposals for a European Single Resolution Mechanism (SRM) for banks and for a Directive on Bank Recovery and Resolution (BRR). The authors find that the proposals are generally well designed and present a consistent approach, yet there is room for improvement, including the streamlining of procedures for the start of resolution, which now entail much overlap in the powers attributed to the various institutions involved (the Commission, the Single Resolution Board and the European Central Bank). The paper makes a number of key recommendations to facilitate discussions for stakeholders and regulators.
