A characterization for complex symmetric Toeplitz operators

In this paper we use orthonormal basis for the Hardy space $H^{2}(\mathbb{T})$, formed by rational functions, to characterize complex symmetric Toeplitz operators on $H^{2}(\mathbb{T})$. As a result, we get examples of these operators whose symbols are non-trigonometric functions.Comment: 7 page

A Review of 'Law's Impunity: Responsibility and the Modern Private Military Company'

The mercenaries and mercenarism are two points of concern for scholars studying the rules of war throughout history. Both in jus ad bellum (JAB) and jus in bellum (JIB) we can find a framework of international law crafted to impede the participation of individuals motivated to take part in hostilities to get private gain. Nevertheless, paradoxically, the problem is when corporations are supported by domestic law to perform serviced in ground combats abroad. In the latter case, Human Rights Law (HRL), International Humanitarian Law (IHL) and International Criminal Law (ICL) present numerous gaps that make it difficult to incriminate corporations, which perpetuate the impunity among private organizations involved in human rights violations in conflict zones

A Review of 'Human Insecurities in Southeast Asia'

Debates on human insecurities are crucial in a changing world that witnesses high social inequality, degradation of environment, social tensions and a growing violation of human rights. Unfortunately, all these issues permeate the social structures of Southeast Asian countries in different ways. In that region civil society faces problems that are diverse, as seen in the political tensions in Thailand, the deterritorialization of indigenous peoples in Philippines and Malaysia, human rights violations in Myanmar, and numerous other challenges. Such setting demands different approaches from institutions and communities to overcome pending risks threatening their populations

Conjugations on the Hardy space H2H^{2}

A conjugation $C$ on a separable complex Hilbert space $\mathcal H$ is an antilinear operator that is isometric and involutive. In this notes, we characterize all conjugations on the Hardy-Hilbert space $H^{2}$ over the disk. In addition, we characterize complex symmetric Toeplitz operators with a special type of these conjugations.Comment:

Os órgãos governamentais brasileiros e a questão do terrorismo na Tríplice Fronteira: divergências de percepções e convergências nas ações

O presente artigo visa analisar como os órgãos governamentais brasileiros se posicionam frente àsacusações de que a Tríplice Fronteira Argentina, Brasil e Paraguai (TF) sirva como base do terrorismointernacional. A subida do terrorismo como tema principal da agenda de segurança internacional após osatentados de 11 de Setembro, somado ao passado dos atentados em território argentino em 1992 e 1994,fez com que a região entrasse na órbita dos discursos e políticas públicas de combate a essa ameaça.Neste sentido, o pós-11 de setembro exigiu do Brasil uma postura mais clara frente ao terrorismo, assimcomo o apoio a mecanismos multilaterais e respostas de suas instituições de segurança e judiciais.Tendo como metodologia entrevistas in loco e pesquisas bibliográficas, nota-se que a postura dos órgãosgovernamentais do Brasil espelharam uma aparente discordância frente aos EUA que não se concretizouno campo das ações
