Environmental changes and violent conflict
This letter reviews the scientific literature on whether and how environmental changes affect the risk of violent conflict. The available evidence from qualitative case studies indicates that environmental stress can contribute to violent conflict in some specific cases. Results from quantitative large-N studies, however, strongly suggest that we should be careful in drawing general conclusions. Those large-N studies that we regard as the most sophisticated ones obtain results that are not robust to alternative model specifications and, thus, have been debated. This suggests that environmental changes may, under specific circumstances, increase the risk of violent conflict, but not necessarily in a systematic way and unconditionally. Hence there is, to date, no scientific consensus on the impact of environmental changes on violent conflict. This letter also highlights the most important challenges for further research on the subject. One of the key issues is that the effects of environmental changes on violent conflict are likely to be contingent on a set of economic and political conditions that determine adaptation capacity. In the authors' view, the most important indirect effects are likely to lead from environmental changes via economic performance and migration to violent conflict. © 2012 IOP Publishing Ltd
Conflict and Livelihood Decisions in the Chittagong Hill Tracts of Bangladesh
__Abstract__
We analyse rural household livelihood and child school enrolment
decisions
in the post-conflict setting of the Chittagong Hill Tracts (CHT) region of
Bangladesh. What makes this paper innovative is the use of current subjective perceptions
regarding the possibility of violence in the future and past actual experiences
of violence in explaining household economic decision-making. Preferences
are endogenous in line with behavioural economics. Regression results show that
heightened subjective perceptions of future violence and past actual experiences
of conflict influence current consumption and child enrolment and could encourage
risky mixed crop cultivation. The trauma emanating from past experiences
combined with current high perceptions of risk of violence may induce bolder
and riskier behaviour in line with prospect theories of risk. Furthermore, a postconflic
Effective-Range Expansion of the Neutron-Deuteron Scattering Studied by a Quark-Model Nonlocal Gaussian Potential
The S-wave effective range parameters of the neutron-deuteron (nd) scattering
are derived in the Faddeev formalism, using a nonlocal Gaussian potential based
on the quark-model baryon-baryon interaction fss2. The spin-doublet low-energy
eigenphase shift is sufficiently attractive to reproduce predictions by the
AV18 plus Urbana three-nucleon force, yielding the observed value of the
doublet scattering length and the correct differential cross sections below the
deuteron breakup threshold. This conclusion is consistent with the previous
result for the triton binding energy, which is nearly reproduced by fss2
without reinforcing it with the three-nucleon force.Comment: 21 pages, 6 figures and 6 tables, submitted to Prog. Theor. Phy
