Consumer/Producer Links in Fair Trade Coffee Networks

Abstract: This article analyzes the multifaceted connections linking consumers and producers in expanding North/South Fair Trade coffee networks. I develop a commodity network framework that builds on the commodity chain tradition, integrating insights from cultural studies, actor–network theory, and conventions approaches. This framework illuminates how material and ideological relations are negotiated across production and consumption arenas. In the case of Fair Trade, progressive ideas and practices related to trust, equality, and global responsibility are intertwined with traditional commercial and industrial conventions. As I demonstrate, the negotiation of these divergent conventions shortens the social distance between Fair Trade coffee consumers and producers. I conclude that by re–linking consumers and producers, commodity network analysis provides a robust entre for academic inquiry and engagement in alternative food politics.

Monitoring and Understanding Trends in Extreme Storms: State of Knowledge

Abstract: The state of knowledge regarding trends and an understanding of their causes is presented for a specific subset of extreme weather and climate types. For severe convective storms (tornadoes, hailstorms, and severe thunderstorms), differences in time and space of practices of collecting reports of events make using the reporting database to detect trends extremely difficult. Overall, changes in the frequency of environments favorable for severe thunderstorms have not been statistically significant. For extreme precipitation, there is strong evidence for a nationally averaged upward trend in the frequency and intensity of events. The causes of the observed trends have not been determined with certainty, although there is evidence that increasing atmospheric water vapor may be one factor. For hurricanes and typhoons, robust detection of trends in Atlantic and western North Pacific tropical cyclone (TC) activity is significantly constrained by data heterogeneity and deficient quantification of internal variab...

The nucleosomal surface as a docking station for Kaposi's sarcoma herpesvirus LANA.

Abstract: Kaposi's sarcoma-associated herpesvirus (KSHV) latency-associated nuclear antigen (LANA) mediates viral genome attachment to mitotic chromosomes. We find that N-terminal LANA docks onto chromosomes by binding nucleosomes through the folded region of histones H2A-H2B. The same LANA residues were required for both H2A-H2B binding and chromosome association. Further, LANA did not bind Xenopus sperm chromatin, which is deficient in H2A-H2B; chromatin binding was rescued after assembly of nucleosomes containing H2A-H2B. We also describe the 2.9-angstrom crystal structure of a nucleosome complexed with the first 23 LANA amino acids. The LANA peptide forms a hairpin that interacts exclusively with an acidic H2A-H2B region that is implicated in the formation of higher order chromatin structure. Our findings present a paradigm for how nucleosomes may serve as binding platforms for viral and cellular proteins and reveal a previously unknown mechanism for KSHV latency.

Population Properties of Compact Objects from the Second LIGO-Virgo Gravitational-Wave Transient Catalog

Abstract: We report on the population of 47 compact binary mergers detected with a false-alarm rate of 0.01 are dynamically assembled. Third, we estimate merger rates, finding RBBH = 23.9-+8.614.3 Gpc-3 yr-1 for BBHs and RBNS = 320-+240490 Gpc-3 yr-1 for binary neutron stars. We find that the BBH rate likely increases with redshift (85% credibility) but not faster than the star formation rate (86% credibility). Additionally, we examine recent exceptional events in the context of our population models, finding that the asymmetric masses of GW190412 and the high component masses of GW190521 are consistent with our models, but the low secondary mass of GW190814 makes it an outlier.

Revisiting the urban politics of climate change

Abstract: In our 2005 paper, Rethinking Sustainable Cities, we made a case for the increasing significance of climate change in the urban politics of sustainability. Taking a multilevel governance perspective, we argued that the ‘urban’ governance of climate protection was not confined to a local arena or to the actions of the state, but rather was orchestrated through the interrelations between global, national and local actors across state/non-state boundaries. We revisit these arguments and examine their validity in the light of the rapidly changing landscape of urban responses to climate change and the growing academic literature in this field. We consider in turn: the ways in which climate change is shaping urban agendas; the utility of multilevel governance perspectives for understanding this phenomenon; and the extent to which we can identify a ‘new’ politics of urban climate change governance and its consequent implications for the development of theory and practice in this field.
