A strategic niche management approach for shaping bio-based economy in Europe
The goal of this paper is to investigate the transition towards a bio-based economy as part of a broader sustainable transition in Europe. To analyse the challenges and opportunities associated with the bio-based economy, we applied the Strategic Niche Management approach to investigate the drivers that boost the emergence of the bio-based economy, the factors hindering it, as well as institutional changes which are at the base of the socio-technological transition. Although considered as just one piece of the sustainability puzzle, the bio-based economy behaves as a socio-technical system on its own, providing valuable hints on systemic transitions
Interference between initial and final state radiation in a QCD medium
We investigate the color coherence pattern between initial and final state
radiation in the presence of a QCD medium. We derive the medium-induced gluon
spectrum of an "asymptotic" parton which suffers a hard scattering and
subsequently crosses the medium. The angular distribution of the induced gluon
spectrum is modified when one includes interference terms between the incoming
and the outgoing parton at finite angle between them. The coherent, incoherent
and soft limits of the medium-induced gluon spectrum are studied. In the soft
limit, we provide a simple and intuitive probabilistic picture which could be
of interest for Monte Carlo implementations. The configuration studied here may
have phenomenological consequences in high energy nuclear collisions.Comment: 9 pages, 2 figures. Typos corrected and added remarks. Accepted for

Poverty Law 101: The Law and History of the U.S. Welfare State
Poverty law will remain marginalized so long as we confine it to a population that we and our students understand as marginal. Tani discusses Professor Waxâs characterization of the âold welfare law framework,â as well as her account of what happened to it, and would not advocate a return to a court-centered, advocacy-oriented approach
An Administrative Right To Be Free from Sexual Violence? Title IX Enforcement in Historical and Institutional Perspective
One of the most controversial administrative actions in recent years is the U.S. Department of Educationâs campaign against sexual assault on college campuses. Using its authority under Title IX of the Education Amendments of 1972 (mandating nondiscrimination on the basis of sex in all educational programs and activities receiving federal funds), the Departmentâs Office for Civil Rights (OCR) has launched an enforcement effort that critics denounce as aggressive, manipulative, and corrosive of individual liberties. Missing from the commentary is a historically informed understanding of why this administrative campaign unfolded as it did. This Article offers crucial context by reminding readers that freedom from sexual violence was once celebrated as a national civil rightâupon the enactment of the Violence Against Women Act of 1994âbut then lost that status in a 5â4 decision by the U.S. Supreme Court. OCRâs recent campaign reflects a legal and political landscape in which at least some potential victims of sexual violence had come to feel rightfully connected to the institutions of the federal government, and then became righteously outraged by the endurance of such violence in their communities. OCRâs campaign also reflects the unique role of federal administrative agencies in this landscape. Thanks to the power of the purse and the conditions that Congress has attached to funding streams, agencies enjoy a powerful form of jurisdiction over particular spaces and institutions. Attempts to harness this jurisdiction in service of aspirational rights claims should not surprise us; indeed, we should expect such efforts to continue. Building on this insight, the Article concludes with a research agenda for other scholars seeking to understand and evaluate OCRâs handiwork
Has saturation physics been observed in deuteron-gold collisions at RHIC?
We have addressed the question of whether saturation (CGC) has been observed
in deuteron-gold collisions at RHIC. We have made a detailed analysis of the
Cronin peak characteristic of the nuclear modification factor measured for d-Au
collisions at mid-rapidity. The Cronin peak which is obtained around GeV may be reproduced at the proper height only by boosting the saturation
momentum by a huge non-perturbative additional component. At forward rapidity,
we get a quantitative agreement with data, reproducing hadron production
spectra and the ratio using a recently developed description of the
small-x physics.Comment: 4 pages, 2 figures. Talk given at 41st Rencontres de Moriond: QCD and
