Longstanding proposals to strengthen implementation of the international human rights treaties have often focused on procedural reforms such as harmonizing methods of work or consolidating ten treaty monitoring bodies into one. This article reviews past reform efforts and then considers proposals to create stronger individual petition mechanisms—including a ‘world court’—as a way of strengthening human rights implementation. After discussing these proposals, the author offers additional ways to make the system more effective and efficient. She rejects the oft-suggested proposal to create a ‘world court’ for human rights, noting legal, organizational, logistical, and financial obstacles. Rather than rushing to tear down the current treaty body system, the author offers a proposal for determining how consolidation of petition proceedings might affect normative standards.

AbstractIn this work we demonstrate customized depolarization spatial patterns by imaging a dynamical time-dependent pixelated retarder. A proof-of-concept of the proposed method is presented, where a liquid–crystal spatial light modulator is used as a spatial retarder that emulates a controlled spatially variant depolarizing sample by addressing a time-dependent phase pattern. We apply an imaging Mueller polarimetric system based on a polarization camera to verify the effective depolarization effect. Experimental validation is provided by temporal integration on the detection system. The effective depolarizance results are fully described within a simple graphical approach which agrees with standard Mueller matrix decomposition methods. The potential of the method is discussed by means of three practical cases, which include non-reported depolarization spatial patterns, including exotic structures as a spirally shaped depolarization pattern.

AbstractCylindrical vector beams (CVBs), being a special kind of beams with spatially variant states of polarizations, are promising in photonics applications, including high-resolution imaging, plasmon excitation, optical trapping, and laser machining. Recently, generating CVBs using metasurfaces has drawn enormous interest owing to their highly designable, multifunctional, and integratable features. However, related studies remain unexplored in the terahertz regime. Here, a generic method for efficiently generating terahertz CVBs carrying orbital angular momentums (OAMs) is proposed and experimentally demonstrated using transmission-type spatial-variant dielectric metasurfaces, which is realized by designing the interference between the two circularly polarized transmission components. This method is based on spin-decoupled phase control allowed by simultaneously manipulating the dynamic phase and geometric phase of each structure, endowing more degree of freedom in designing the vector beams. Two types of metasurfaces which respectively generate polarization-dependent terahertz vector vortex beams (VVBs) and vector Bessel beams (VBBs) are experimentally characterized. The proposed method opens a new window to generate versatile vector beams, providing new capabilities in developing novel, compact, and high-performance devices applicable to broad electromagnetic spectral regimes.

The Individual

Abstract A camp may be described as a temporary space in which individuals receive humanitarian relief and protection until a durable solution can be found to their situation. The camp environment is often riddled with contradictions—the camp can be a place of refuge while at the same time, a place of overcrowding, exclusion and suffering. This article asks to what extent removal of an individual from state A to state B, where he or she will have to live in a camp, is a breach of state A’s human rights law obligations. It argues that even if encampment in state B will expose the individual to terrible conditions, it is unlikely that they will be able to successfully challenge a removal decision before international human rights courts and/or treaty monitoring bodies.
