Globalization, Gender, and Poverty in the Senegal River Valley

In an impressive attempt to guarantee food security, well over two billion dollars have been invested in the modernization of the agrarian economy in the Senegal River Valley. But, even though two huge dams and thousands of village-based irrigation schemes have been constructed since the late 1970s, food security is still as illusive as ever. This study attempts to explain why. In doing so it focuses on the impact of donor-dominated macro-structural change on gender and class relations. This analytical perspective has two benefits: First, it reveals the risks posed by foreign domination of development programs for different segments of the rural population. Second, it points to a critical element in a new approach to improving farm productivity and food security�-�improving women's access to land and technology.Foreign aid, structural adjustment, food security, women's land rights, inequality, JEL Codes: N57, Q01,

Measurements of ttˉt\bar{t} differential cross-sections of highly boosted top quarks decaying to all-hadronic final states in pppp collisions at s=13 \sqrt{s}=13\, TeV using the ATLAS detector

Measurements are made of differential cross-sections of highly boosted pair-produced top quarks as a function of top-quark and $t\bar{t}$ system kinematic observables using proton--proton collisions at a center-of-mass energy of $\sqrt{s} = 13$ TeV. The data set corresponds to an integrated luminosity of $36.1$ fb$^{-1}$, recorded in 2015 and 2016 with the ATLAS detector at the CERN Large Hadron Collider. Events with two large-radius jets in the final state, one with transverse momentum $p_{\rm T} > 500$ GeV and a second with $p_{\rm T}>350$ GeV, are used for the measurement. The top-quark candidates are separated from the multijet background using jet substructure information and association with a $b$-tagged jet. The measured spectra are corrected for detector effects to a particle-level fiducial phase space and a parton-level limited phase space, and are compared to several Monte Carlo simulations by means of calculated $\chi^2$ values. The cross-section for $t\bar{t}$ production in the fiducial phase-space region is $292 \pm 7 \ \rm{(stat)} \pm 76 \rm{(syst)}$ fb, to be compared to the theoretical prediction of $384 \pm 36$ fb
