    In light of regulators\u27 renewed attention, this article discusses recent events, reviews AML enforcement actions against securities firms, and identifies the compliance risks they suggest. The article concludes that the time has come for broker-dealers and advisers alike to take a holistic view of compliance and their AML risks, and to prepare for enhanced oversight and regulation

    Seeds of Change: Corn Seed Mixtures for Resistance Management and Integrated Pest Management

    The use of mixtures of transgenic insecticidal seed and nontransgenic seed to provide an in-field refuge for susceptible insects in insect-resistance-management (IRM) plans has been considered for at least two decades. However, the U.S. Environmental Protection Agency has only recently authorized the practice. This commentary explores issues that regulators, industry, and other stakeholders should consider as the use of biotechnology increases and seed mixtures are implemented as a major tactic for IRM. We discuss how block refuges and seed mixtures in transgenic insecticidal corn, Zea mays L., production will influence integrated pest management (IPM) and the evolution of pest resistance. We conclude that seed mixtures will make pest monitoring more difficult and that seed mixtures may make IRM riskier because of larval behavior and greater adoption of insecticidal corn. Conversely, block refuges present a different suite of risks because of adult pest behavior and the lower compliance with IRM rules expected from farmers. It is likely that secondary pests not targeted by the insecticidal corn as well as natural enemies will respond differently to block refuges and seed mixtures

    Pest population dynamics are related to a continental overwintering gradient

    Overwintering success is an important determinant of arthropod populations that must be considered as climate change continues to influence the spatiotemporal population dynamics of agricultural pests. Using a long-term monitoring database and biologically relevant overwintering zones, we modeled the annual and seasonal population dynamics of a common pest, Helicoverpa zea (Boddie), based on three overwintering suitability zones throughout North America using four decades of soil temperatures: the southern range (able to persist through winter), transitional zone (uncertain overwintering survivorship), and northern limits (unable to survive winter). Our model indicates H. zea population dynamics are hierarchically structured with continental-level effects that are partitioned into three geographic zones. Seasonal populations were initially detected in the southern range, where they experienced multiple large population peaks. All three zones experienced a final peak between late July (southern range) and mid-August to mid-September (transitional zone and northern limits). The southern range expanded by 3% since 1981 and is projected to increase by twofold by 2099 but the areas of other zones are expected to decrease in the future. These changes suggest larger populations may persist at higher latitudes in the future due to reduced low-temperature lethal events during winter. Because H. zea is a highly migratory pest, predicting when populations accumulate in one region can inform synchronous or lagged population development in other regions. We show the value of combining long-term datasets, remotely sensed data, and laboratory findings to inform forecasting of insect pests

    The Crowdsourced Replication Initiative: Investigating Immigration and Social Policy Preferences. Executive Report.

    In an era of mass migration, social scientists, populist parties and social movements raise concerns over the future of immigration-destination societies. What impacts does this have on policy and social solidarity? Comparative cross-national research, relying mostly on secondary data, has findings in different directions. There is a threat of selective model reporting and lack of replicability. The heterogeneity of countries obscures attempts to clearly define data-generating models. P-hacking and HARKing lurk among standard research practices in this area.This project employs crowdsourcing to address these issues. It draws on replication, deliberation, meta-analysis and harnessing the power of many minds at once. The Crowdsourced Replication Initiative carries two main goals, (a) to better investigate the linkage between immigration and social policy preferences across countries, and (b) to develop crowdsourcing as a social science method. The Executive Report provides short reviews of the area of social policy preferences and immigration, and the methods and impetus behind crowdsourcing plus a description of the entire project. Three main areas of findings will appear in three papers, that are registered as PAPs or in process

    El proyecto fue una formulación exitosa de un plan parcial que incluyó usos de vivienda y comercio, se desarrolló en respuesta a la problemática habitacional y social del sector Las Brisas en la localidad de Fontibón y es en la actualidad un modelo en cuanto a sus gestiones de tiempo; ya que estuvo proyectado para tomarse 12 meses, cumplió con los lineamientos establecidos por los interesados y de costo mediante el seguimiento de un presupuesto que se siguió según lo proyectado, de esta manera se entregó el proyecto cuyo objetivo principal fue realizar el diseño urbano en el cual se cumplieron con requerimientos sociales, ambientales, urbanos y legales del sector.The project was a successful formulation of a partial plan that included uses of housing and commerce, was developed in response to the housing and social problems of the Las Brisas sector in the town of Fontibón and is currently a model in terms of its efforts to weather; Since it was projected to take 12 months, it complied with the guidelines established by the interested parties and by cost by following a budget that was followed as projected, thus the project was delivered whose main objective was to carry out urban design in the which were fulfilled with social, environmental, urban and legal requirements of the sector

    Sunflower genetic, genomic and ecological resources

    Long a major focus of genetic research and breeding, sunflowers (Helianthus) are emerging as an increasingly important experimental system for ecological and evolutionary studies. Here, we review the various attributes of wild and domesticated sunflowers that make them valuable for ecological experimentation and describe the numerous publicly available resources that have enabled rapid advances in ecological and evolutionary genetics. Resources include seed collections available from germplasm centres at the USDA and INRA, genomic and EST sequences, mapping populations, genetic markers, genetic and physical maps and other forward- and reverse-genetic tools. We also discuss some of the key evolutionary, genetic and ecological questions being addressed in sunflowers, as well as gaps in our knowledge and promising areas for future research
