    Chapter 15 South Koreaā€™s Green New Deal 2.0

    Get PDF
    In recent years, the Green New Deal has moved from relative obscurity to front and centre of policy discussions and public debates about how to respond to the climate crisis. It has been credited with radically changing the nature of the conversation on climate change and with re-energizing the environmental movement at a critical time. All Green New Deal proposals share an emphasis on the need for governments (rather than markets) to lead the energy transition. However, they differ in other respects. This Handbook analyses the fundamentals underlying all Green New Deals as well as exploring national and regional variations. It is divided into three parts. The first part examines the political economy of the Green New Deal focussing not just on how proposals will be costed but also on opportunities for a fundamental transformation of both national economies and the global economic system. The second part explores issues of justice, which are central to many Green New Deal proposals, including Indigenous rights, racial and gender equity, and justice for the Global South. In the third part, authors detail case studies of Green New Deal proposals and plans at the local, national, and regional level. This book will be an invaluable research and reference volume for students and scholars in economics, politics, sociology, geography, and environmental studies. It should also be of interest to those actively involved in climate and environmental policymaking

    Highly parallel oligonucleotide purification and functionalization using reversible chemistry

    Get PDF
    We have developed a cost-effective, highly parallel method for purification and functionalization of 5ā€²-labeled oligonucleotides. The approach is based on 5ā€²-hexa-His phase tag purification, followed by exchange of the hexa-His tag for a functional group using reversible reaction chemistry. These methods are suitable for large-scale (micromole to millimole) production of oligonucleotides and are amenable to highly parallel processing of many oligonucleotides individually or in high complexity pools. Examples of the preparation of 5ā€²-biotin, 95-mer, oligonucleotide pools of >40K complexity at micromole scale are shown. These pools are prepared in up to ~16% yield and 90ā€“99% purity. Approaches for using this method in other applications are also discussed

    Reproductive Success of Eastern Bluebirds (Siala sialis) on Suburban Golf Courses

    Understanding the role of green space in urbanā€”suburban landscapes is becoming critical for bird conservation because of rampant habitat loss and conversion. Although not natural habitat, golf courses could play a role in bird conservation if they support breeding populations of some native species, yet scientists remain skeptical. In 2003ā€“2009, we measured reproduction of Eastern Bluebirds (Siala sialis) in Virginia on golf courses and surrounding reference habitats, of the type that would have been present had golf courses not been developed on these sites (e.g., recreational parks, cemeteries, agriculture land, and college campus). We monitored \u3e650 nest boxes and 2,255 nest attempts (n = 1,363 golf course, n = 892 reference site). We used an information-theoretic modeling approach to evaluate whether conditions on golf courses affected timing of breeding, investment, or nest productivity compared with nearby reference sites. We found that Eastern Bluebirds breeding on golf courses reproduced as well as those breeding in other disturbed habitats. Habitat type had no effect on initial reproductive investment, including date of clutch initiation or clutch size ( = 4 eggs). During incubation and hatching, eggs in nests on golf courses had higher hatching rates (80%) and brood sizes ( = 4.0 nestlings brood-1) than nests on reference sites (75% hatching rate; = 3.8 nestlings brood-1). Mortality of older nestlings was also lower on golf courses and, on average, golf course nests produced 0.3 more fledglings than nests on reference sites. Thus, within a matrix of human-dominated habitats, golf courses may support productive populations of some avian species that can tolerate moderate levels of disturbance, like Eastern Bluebirds

    Boson Stars: Alternatives to primordial black holes?

    Get PDF
    The present surge for the astrophysical relevance of boson stars stems from the speculative possibility that these compact objects could provide a considerable fraction of the non-baryonic part of dark matter within the halo of galaxies. For a very light `universal' axion of effective string models, their total gravitational mass will be in the most likely range of \sim 0.5 M_\odot of MACHOs. According to this framework, gravitational microlensing is indirectly ``weighing" the axion mass, resulting in \sim 10^{-10} eV/c^2. This conclusion is not changing much, if we use a dilaton type self-interaction for the bosons. Moreover, we review their formation, rotation and stability as likely candidates of astrophysical importance.Comment: 14 pages, uses REVTeX, 1 postscript figur

    Ground performance of the High-Energy Focusing Telescope (HEFT) attitude control system

    Get PDF
    The High Energy Focusing Telescope (HEFT) is a balloon-borne, hard x-ray/gamma ray (20-70 keV) astronomical experiment. HEFT's 10 arcminute field of view and 1 arcminute angular resolution place challenging demands on its attitude control system (ACS). A microprocessor-based ACS has been developed to manage target acquisition and sidereal tracking. The ACS consists of a variety of sensors and actuators, with provisions for 2-way ground communication, all controlled by an on-board computer. Ground based pointing performance measurements indicate 1Ļƒ jitter of 7" and gyro drift rates of <1" s^(-1). Jitter is expected to worsen in the flight environment, but star tracker data are expected to reduce drift rates significantly, enabling a predicted 1Ļƒ absolute attitude determination of ā‰„4.7". HEFT is scheduled for flight in Spring 2004

    Does the planning system in England deliver a sustainable and resilient built environment? A study of the experience of town planners

    Get PDF
    The case has been made in the reports of the Intergovernmental Panel on Climate Changes for the crucial role of the built environment in mitigating the worst excesses of a warming global climate and in protecting people through adaptation. Town planners are essential actors in delivering sustainable and resilient urbanism. Given that legislation is implemented by people, the study aimed to examine how town planners experienced and thought about the changing legislation and how they understood the concepts of ā€˜sustainabilityā€™ and ā€˜resilienceā€™ in the built environment. Semi-structured interviews were conducted with 19 planners working in England who had at least seven yearsā€™ experience. In the analysis, we explored meanings of sustainability and of resilience, and how these concepts were seen as incorporated in legislation. Sustainability was seen by the participants as embedded in regulations but its realisation varied substantially. Tensions were evident between the three pillars of environment, society and economy. ā€˜Resilienceā€™ as a concept was poorly understood and legislative support was patchy at best: while flooding features extensively in local plans, wider issues of climate impact such as overheating are not comprehensively addressed. The conclusions are that planners are often frustrated in their attempts to develop a more sustainable built environment and that the current planning system is inadequate to deliver consistently sustainable and resilient outcomes. However, alignment between sustainability goals and professional identity were also noted, offering avenues to explore beyond the institutional constraints of legislation

    Regime shifts and panarchies in regional scale social-ecological water systems

    Get PDF
    In this article we summarize histories of nonlinear, complex interactions among societal, legal, and ecosystem dynamics in six North American water basins, as they respond to changing climate. These case studies were chosen to explore the conditions for emergence of adaptive governance in heavily regulated and developed social-ecological systems nested within a hierarchical governmental system. We summarize resilience assessments conducted in each system to provide a synthesis and reference by the other articles in this special feature. We also present a general framework used to evaluate the interactions between society and ecosystem regimes and the governance regimes chosen to mediate those interactions. The case studies show different ways that adaptive governance may be triggered, facilitated, or constrained by ecological and/or legal processes. The resilience assessments indicate that complex interactions among the governance and ecosystem components of these systems can produce different trajectories, which include patterns of (a) development and stabilization, (b) cycles of crisis and recovery, which includes lurches in adaptation and learning, and (3) periods of innovation, novelty, and transformation. Exploration of cross scale (Panarchy) interactions among levels and sectors of government and society illustrate that they may constrain development trajectories, but may also provide stability during crisis or innovation at smaller scales; create crises, but may also facilitate recovery; and constrain system transformation, but may also provide windows of opportunity in which transformation, and the resources to accomplish it, may occur. The framework is the starting point for our exploration of how law might play a role in enhancing the capacity of social-ecological systems to adapt to climate change

    The Praise Paradox: When and Why Praise Backfires in Children With Low Self-Esteem

    Get PDF
    In contemporary Western society, many adults use praise to boost children's self-esteem. Accordingly, they might praise those who seem to need it the most: children with low self-esteem. In this article, we review research showing that certain types of praise can backfire, especially in children with low self-esteem. Adults are inclined to give children with low self-esteem person praise (e.g., ā€œYou're smart!ā€) and inflated praise (e.g., ā€œThat's incredibly beautiful!ā€). Paradoxically, such praise can lower these children's motivation and feelings of self-worth in the face of setbacks (e.g., when they struggle or fail). Lowered feelings of self-worth, in turn, might invite more person praise and inflated praise from adults, creating a self-sustaining downward spiral. We propose a transactional model to shed light on this apparent praise paradox, and we describe the model's implications for theory and research
