    Implicit norms

    Robert Brandom has developed an account of conceptual content as instituted by social practices. Such practices are understood as being implicitly normative. Brandom proposed the idea of implicit norms in order to meet some requirements imposed by Wittgenstein’s remarks on rule-following: escaping the regress of rules on the one hand, and avoiding mere regular behavior on the other. Anandi Hattiangadi has criticized this account as failing to meet such requirements. In what follows, I try to show how the correct understanding of sanctions and the expressivist reading of the issue can meet these challenges

    Horticultural markets promote alien species invasions : an Estonian case study of herbaceous perennials

    Gardening is a popular pastime, but commercial horticulture is responsible for the introduction of alien species and contributes to invasions in a variety of ways. Although an extensive international literature is available on plant invasions, it is still important at the national level to examine the influence of local factors. Accordingly, 17 nurseries in Estonia that cultivated and sold perennial alien species were selected, and a list of species and prices was compiled. The relationships between species status, and factors such as their abundance in the wild were examined statistically. A qualitative list of the nationally problematic species among herbaceous perennials was also completed. A total of 880 taxa were recorded, of which 10.3% were native and 89.7% alien. In all, 87.3% of the alien species were still confined to cultivated areas. The ecological and socio-economic characteristics of the taxa were described, and lists of the families of casual, naturalised and invasive aliens were provided. Both native and increasing wild alien species have a very similar profile on the market. Alien species that are less expensive, widely available and have more cultivars per species on the market are also more likely to escape. The invasive status and abundance of escaped aliens in an area increases with residence time. In general, socio-economic factors create new and reflect previous propagule pressures from commercial horticulture, which continuously increase the likelihood of alien species surviving and invading new areas. Our findings suggest that these national socioeconomic market-related factors explain much of the invasiveness of various perennial ornamental species, and therefore regional and national authorities urgently need to regulate and control the ornamental plant trade to diminish the risk of new invasions

    Unmet Needs of Unaccompanied Minors from Central America: Perceptions of Professionals from Multiple Sectors

    Background: In recent years, there has been a significant influx of Central American youth who cross the U.S.-Mexico border without a parent or legal guardian. While federal procedures are established to oversee the treatment and placement of unaccompanied minors, less is known about the needs of unaccompanied minors and available services afterthey are placed in appropriate custody. Methods: Purposive and strategic sampling of professionals from medical, social work, education and legal fields was conducted. Fourteen informants were recruited across the U.S. for confidential semi-structured interviews, which were audio recorded and transcribed in 2016 to 2017. Standard anthropological methods were employed, including immersion and crystallization techniques that incorporated within-case and across-case analytic strategies. Results: Recruited informants had previous or current direct experience working with immigrant minors for three or more years in addition to extensive public health experience. Unaccompanied minors were described as predominantly adolescent boys, ranging from 2 to 18 years old. Children faced unmet mental, medical and psychosocial needs that are interconnected and largely unmet due to children’s legal status and ineligibility to access services in most jurisdictions. The most pressing challenge affecting the health of youth was their immigration status. Across sectors,informants revealed an imbalance between the growing demand for services, including legal counsel, and the limited supply of professionals and well-funded services to meet children’s complex needs. Informants emphasized the value of trauma-informed practice, Spanish language proficiency, child-informed practice and intercultural awareness and humility towards their clients as key features of equipped professionals working with this vulnerable population. Regardless of sector, professionals emphasized the importance of culturally-informed care to immigrant youth. Building these skills is associated with greater confidence to provide services to unaccompanied minors, many of whom have experienced as significant burden of childhood trauma. Conclusions: The health needs of unaccompanied minors are complex and span across medical, social work, education, and legal fields. Interdisciplinary collaboration is needed to address the challenges faced by unaccompanied minors in their efforts to integrate themselves into their new communities and promote their resilience. Promising initiatives include co-location of inter-sector services for increased access and efficiency of services and development of professional trainings and resources for professionals in sectors that serve this population

    Bridging the gap between policy and science in assessing the health status of marine ecosystems

    Get PDF
    Human activities, both established and emerging, increasingly affect the provision of marine ecosystem services that deliver societal and economic benefits. Monitoring the status of marine ecosystems and determining how human activities change their capacity to sustain benefits for society requires an evidence-based Integrated Ecosystem Assessment approach that incorporates knowledge of ecosystem functioning and services). Although, there are diverse methods to assess the status of individual ecosystem components, none assesses the health of marine ecosystems holistically, integrating information from multiple ecosystem components. Similarly, while acknowledging the availability of several methods to measure single pressures and assess their impacts, evaluation of cumulative effects of multiple pressures remains scarce. Therefore, an integrative assessment requires us to first understand the response of marine ecosystems to human activities and their pressures and then develop innovative, cost-effective monitoring tools that enable collection of data to assess the health status of large marine areas. Conceptually, combining this knowledge of effective monitoring methods with cost-benefit analyses will help identify appropriate management measures to improve environmental status economically and efficiently. The European project DEVOTES (DEVelopment Of innovative Tools for understanding marine biodiversity and assessing good Environmental Status) specifically addressed t hese topics in order to support policy makers and managers in implementing the European Marine Strategy Framework Directive. Here, we synthesize our main innovative findings, placing these within the context of recent wider research, and identifying gaps and the major future challenges
