Resonansi istilah maupun seruan jihâd sungguh terasa lebih “menggetarkan” nurani kaum Muslim, terlebih  bagi pemeluk agama lain, daripada penggunaan kosakata lainnya yang bermakna serupa. Apalagi, jika istilah atau seruan itu diiringi dengan pekik-suara Allâhu Akbar!!! tiga kali, seolah-olah genderang perang-suci agama baru saja ditabuh dan pasukan mulai dikomando menuju the killing field. Tidak jarang, teriakan keras Allâhu Akbar pun diserupakan dengan kesiapan ber-jihâd, dalam arti berperang secara fisik melawan orang-orang yang “mempertontonkan” perilaku munkar, batil, kâfir, dan dhalim dalam segala bentuk, level, maupun konteksnya sesuai dengan klaim-persepsif kebenaran sepihak pada golongan tertentu. Dalam realitasnya, para pelaku aksi-aksi kekerasan seringkali menggunakan istilah jihâd sebagai dasar-pembenar atas tindakan yang beraneka motif. Persoalannya, apakah jihâd itu “berwajah” tunggal? Berlaku untuk semua konteks? Identik dengan kekerasan atau peperangan? Atau masih adakah ruang tersisa untuk memaknakannya kembali menurut ragam konteksnya sebagai perspektif baru yang mencerahkan dan membebaskan umat dari belenggu yang bernuansa kengerian

De León provides a critique of “Prevention through Deterrence,” the federal border enforcement policy that encourages migrants to cross in areas characterized by extreme environmental conditions and a high risk of death. This policy has failed to deter border crossers while successfully turning the rugged terrain of southern Arizona into a killing field for all undocumented migrants. The threatening space of the U.S.-Mexico border poses particular threats to children and youth who are attempting to cross, especially when crossing without adult family members. Guides and smugglers typically facilitate the movement of young people, or—which is equally dangerous—children increasingly attempt to cross alone or with groups of other children. As children and youth are apprehended trying to enter the United States, they also enter a complicated system of immigration enforcement and detention.

AbstractLet ℱ be a Kähler foliation on a compact Riemannian manifold M. If the transversal scalar curvature of ℱ is nonzero constant, then any transversal conformal field is a transversal Killing field; and if the transversal Ricci curvature is nonnegative and positive at some point, then there are no transversally holomorphic fields.

The static patch of de Sitter spacetime and the Rindler wedge of Minkowski spacetime are causal diamonds admitting a true Killing field, and they behave as thermodynamic equilibrium states under gravitational perturbations. We explore the extension of this gravitational thermodynamics to all causal diamonds in maximally symmetric spacetimes. Although such diamonds generally admit only a conformal Killing vector, that seems in all respects to be sufficient. We establish a Smarr formula for such diamonds and a ``first law" for variations to nearby solutions. The latter relates the variations of the bounding area, spatial volume of the maximal slice, cosmological constant, and matter Hamiltonian. The total Hamiltonian is the generator of evolution along the conformal Killing vector that preserves the diamond. To interpret the first law as a thermodynamic relation, it appears necessary to attribute a negative temperature to the diamond, as has been previously suggested for the special case of the static patch of de Sitter spacetime. With quantum corrections included, for small diamonds we recover the ``entanglement equilibrium'' result that the generalized entropy is stationary at the maximally symmetric vacuum at fixed volume, and we reformulate this as the stationarity of free conformal energy with the volume not fixed.

Kilmister (1) has considered dynamical systems specified by coordinates q( = 1, 2, , n) and a Lagrangian(with summation convention). He sought to determine generally covariant conditions for the existence of a first integral, , linear in the velocities. He showed that it is not, as is usually stated, necessary that there must exist an ignorable coordinate (equivalently, that b must be a Killing field:where covariant derivation is with respect to a). On the contrary, a singular integral, in the sense that for all time if satisfied initially, need not be accompanied by an ignorable coordinate.

In the present paper, we study the global behaviour of geodesics of a Randers metric, defined on Finsler surfaces of revolution, obtained as the solution of the Zermelo’s navigation problem. Our wind is not necessarily a Killing field. We apply our findings to the case of the topological cylinder R×S1 and describe in detail the geodesics behaviour, the conjugate and cut loci.



Einstein's equations for empty space are solved for the class of metrics which admit a family of hypersurface-orthogonal, non-shearing, diverging null curves. Some of these metrics may be considered as representing a simple kind of spherical, outgoing radiation. (Among them are solutions admitting no Killing field whatsoever.) Examples of solutions to the Maxwell-Einstein equations with a similar geometry are also given.
