Civil Society Engagement in Free Trade Negotiations: CAFTA Opposition Movements in El Salvador
This article analyzes civil society participation in the free trade debate by focusing on networks that opposed the Central American Free Trade Agreement (CAFTA) in El Salvador. Drawing on documents, observations, and semi-structured interviews with civil society leaders, two kinds of opposition coalitions are identified. âCritic negotiators,â emphasizing active engagement and policy research, used the limited participation space opened by authorities to push for reform. âTransgressive resisters,â repudiating the formal consultation process, deployed confrontational tactics and posed more fundamental challenges. This work uses social movement theory to explore coalition resource mobilization, the role of movement entrepreneurs, strategic decision-making, mechanisms linking local and transnational activists, and the dynamics of intra-movement competition
From the Streets to the Chamber: Social Movements and the Mining Ban in El Salvador
Following an extended anti-mining campaign, El Salvador became the first country to adopt a legal ban on all forms of metallic mining. This article uses process tracing to map direct, indirect and mediated linkages between the anti-mining mobilization and the formal adoption of a mining prohibition by the national legislature in 2017. It draws on 78 interviews with campaign activists, legislators, government officials, business leaders and legal teams, and combines this information with legislative documents and reports, public opinion data, legal documents from an investment dispute filed against the Salvadoran government, and blogs and website of the Mesa Nacional Frente a la MinerĂa MetĂĄlica. This analysis gives particular attention to the spatial reach and breadth of the anti-mining networks; fissures within and situational realignment of the political elite; and the strategic use of diverse institutional openings (docking points), some of which were adapted to new purposes by movement entrepreneurs. Although major obstacles to sustainable development and environmental protection remain in El Salvador, this article identifies a set of iterative interactions between activist alliances and institutional actors that can successfully contribute to policy change
Los empresarios y el estado posrevolucionario: el reordenamiento de las ĂŠlites y la nueva estrategia de colaboraciĂłn en Nicaragua
This study examines the political processes that affected the reconfiguration of the economic elite in Nicaragua during the 1980s and 1990s, and documents the changing patterns of relations between businessmen and the State after the return to power of Sandinista leader Daniel Ortega in 2007. Based on documents and interviews with representatives of COSEP, the Government and NGOs, this article traces the rise and fall of the factions of the traditional elite during the Sandinista Revolution and analyzes the impact of market reform on emerging dynamics during the post-revolutionary transitions that followed. These experiences help explain the new strategy of the business sector of sustained negotiation and collaboration with the government after the re-election and growing political dominance of Ortega.
Este estudio examina los procesos polĂticos que afectaron la reconfiguraciĂłn de la ĂŠlite econĂłmica en Nicaragua durante los aĂąos 1980 y 1990, y documenta los patrones cambiantes de las relaciones entre los empresarios y el Estado tras el regreso al poder del lĂder sandinista Daniel Ortega en 2007. BasĂĄndose en documentos y entrevistas con representantes de COSEP, el Gobierno y las ONG, este artĂculo traza el auge y la caĂda de las facciones de la ĂŠlite tradicional durante la RevoluciĂłn Sandinista y analiza el impacto de la reforma del mercado en la dinĂĄmica emergente durante las transiciones postrevolucionarias que siguieron. Estas experiencias ayudan a explicar la nueva estrategia del sector empresarial de negociaciĂłn sostenida y colaboraciĂłn con el gobierno tras la reelecciĂłn y creciente dominio polĂtico de Ortega. El artĂculo concluye levantando preguntas sobre los puntos de tensiĂłn y los problemas no resueltos que quedan.

The \u3cem\u3eChlamydomonas\u3c/em\u3e Genome Reveals the Evolution of Key Animal and Plant Functions
Chlamydomonas reinhardtii is a unicellular green alga whose lineage diverged from land plants over 1 billion years ago. It is a model system for studying chloroplast-based photosynthesis, as well as the structure, assembly, and function of eukaryotic flagella (cilia), which were inherited from the common ancestor of plants and animals, but lost in land plants. We sequenced the âź120-megabase nuclear genome of Chlamydomonas and performed comparative phylogenomic analyses, identifying genes encoding uncharacterized proteins that are likely associated with the function and biogenesis of chloroplasts or eukaryotic flagella. Analyses of the Chlamydomonas genome advance our understanding of the ancestral eukaryotic cell, reveal previously unknown genes associated with photosynthetic and flagellar functions, and establish links between ciliopathy and the composition and function of flagella
Performance of CMS muon reconstruction in pp collision events at sqrt(s) = 7 TeV
The performance of muon reconstruction, identification, and triggering in CMS
has been studied using 40 inverse picobarns of data collected in pp collisions
at sqrt(s) = 7 TeV at the LHC in 2010. A few benchmark sets of selection
criteria covering a wide range of physics analysis needs have been examined.
For all considered selections, the efficiency to reconstruct and identify a
muon with a transverse momentum pT larger than a few GeV is above 95% over the
whole region of pseudorapidity covered by the CMS muon system, abs(eta) < 2.4,
while the probability to misidentify a hadron as a muon is well below 1%. The
efficiency to trigger on single muons with pT above a few GeV is higher than
90% over the full eta range, and typically substantially better. The overall
momentum scale is measured to a precision of 0.2% with muons from Z decays. The
transverse momentum resolution varies from 1% to 6% depending on pseudorapidity
for muons with pT below 100 GeV and, using cosmic rays, it is shown to be
better than 10% in the central region up to pT = 1 TeV. Observed distributions
of all quantities are well reproduced by the Monte Carlo simulation.Comment: Replaced with published version. Added journal reference and DO

X-ray emission from the Sombrero galaxy: discrete sources
We present a study of discrete X-ray sources in and around the
bulge-dominated, massive Sa galaxy, Sombrero (M104), based on new and archival
Chandra observations with a total exposure of ~200 ks. With a detection limit
of L_X = 1E37 erg/s and a field of view covering a galactocentric radius of ~30
kpc (11.5 arcminute), 383 sources are detected. Cross-correlation with Spitler
et al.'s catalogue of Sombrero globular clusters (GCs) identified from HST/ACS
observations reveals 41 X-rays sources in GCs, presumably low-mass X-ray
binaries (LMXBs). We quantify the differential luminosity functions (LFs) for
both the detected GC and field LMXBs, whose power-low indices (~1.1 for the
GC-LF and ~1.6 for field-LF) are consistent with previous studies for
elliptical galaxies. With precise sky positions of the GCs without a detected
X-ray source, we further quantify, through a fluctuation analysis, the GC LF at
fainter luminosities down to 1E35 erg/s. The derived index rules out a
faint-end slope flatter than 1.1 at a 2 sigma significance, contrary to recent
findings in several elliptical galaxies and the bulge of M31. On the other
hand, the 2-6 keV unresolved emission places a tight constraint on the field
LF, implying a flattened index of ~1.0 below 1E37 erg/s. We also detect 101
sources in the halo of Sombrero. The presence of these sources cannot be
interpreted as galactic LMXBs whose spatial distribution empirically follows
the starlight. Their number is also higher than the expected number of cosmic
AGNs (52+/-11 [1 sigma]) whose surface density is constrained by deep X-ray
surveys. We suggest that either the cosmic X-ray background is unusually high
in the direction of Sombrero, or a distinct population of X-ray sources is
present in the halo of Sombrero.Comment: 11 figures, 5 tables, ApJ in pres
