Evaluation of ecological migrants’ adaptation to their new living area in Three-River Headwater wetlands, China

AbstractEcological migration is an important policy for sustainable ecosystem management, which usually relocates a large number of residents from their traditional living regions with high ecological sensitivity to other areas with low ecological sensitivity as part of the government's initiative to restore and recover seriously degraded ecosystems. Evaluation of ecological migrants’ adaptation to their new living area is essential for assessing the success of migration and directing the design and implementation of measures to improve the effectiveness of migration. In this research, the adaptation of ecological migrants to their new living area was investigated and analyzed in Three-River Headwater region, a typical and significant migration area in China. The questionnaire survey method was applied. Three many issues related to migrants’ adaptation were discussed, namely the determination of suitable migration population size, the choice of follow-up industry and the integration issue in ecological migration. The result indicated that the majority of migrants could adapt to their new living places and could live with a better life standard. In spite of this, the unsuitability for new work was the major problem for the ecological migration with 72% people unable for their new work

Partial Wave Analysis of J/ψ→γ(K+K−π+π−)J/\psi \to \gamma (K^+K^-\pi^+\pi^-)

BES data on $J/\psi \to \gamma (K^+K^-\pi^+\pi^-)$ are presented. The $K^*\bar K^*$ contribution peaks strongly near threshold. It is fitted with a broad $0^{-+}$ resonance with mass $M = 1800 \pm 100$ MeV, width $\Gamma = 500 \pm 200$ MeV. A broad $2^{++}$ resonance peaking at 2020 MeV is also required with width $\sim 500$ MeV. There is further evidence for a $2^{-+}$ component peaking at 2.55 GeV. The non-$K^*\bar K^*$ contribution is close to phase space; it peaks at 2.6 GeV and is very different from $K^{*}\bar{K^{*}}$.Comment: 15 pages, 6 figures, 1 table, Submitted to PL

Evidence of Color Coherence Effects in W+jets Events from ppbar Collisions at sqrt(s) = 1.8 TeV

We report the results of a study of color coherence effects in ppbar collisions based on data collected by the D0 detector during the 1994-1995 run of the Fermilab Tevatron Collider, at a center of mass energy sqrt(s) = 1.8 TeV. Initial-to-final state color interference effects are studied by examining particle distribution patterns in events with a W boson and at least one jet. The data are compared to Monte Carlo simulations with different color coherence implementations and to an analytic modified-leading-logarithm perturbative calculation based on the local parton-hadron duality hypothesis.Comment: 13 pages, 6 figures.
