从“卡翁达诉南非共和国总统案”看外交保护的另一种国家实践

外交保护的实施过程可以区分为国内决策阶段和利用国际法向侵害本国人权利的相对国采取措施的阶段。因此,在国内决策阶段中有一种不可忽视的实践,那就是认为从国内法角度来看国家负有以一切可能方式保护本国公民的义务。但是,实际上外交是国家行为,它代表国民的整体利益。因而在具体个案中可能需要从大局出发采取和缓的方式对权益受侵害的国民进行保护或放弃保护。但,必须建立有效的机制以沟通被害者和实行外交保护的公权力机构。在对公共利益和私人利益进行取舍时,可能需要考虑相应的补偿问题。以此为出发点,对将以外交保护方式保护国民作为国家宪法义务的国家实践进行研究。

‘The sleep has been rubbed from their eyes’: social citizenship and the reproduction of local hierarchies in rural Hungary and Romania

In this paper, we make three interrelated points. First, while much of the recent literature on new forms of citizenship has focused on the diversity of large cities and new forms of migration, we seek to establish rural sites as important arenas for negotiating citizenship. We stress that far from being homogeneous, villages in their struggles over belonging are affected by long-standing diversity as well as global discourses. Second, we seek to complicate the interpretation of the demise of socialism as a radical break manifested in a diminished role of the state. We show that if the central state retreats, local state actors may gain in importance for local negotiations of citizenship. Third, we explore how the local state actors sometimes use their new powers over social rights to recreate boundaries of belonging through public performances tied to the administration of these rights. We go on to explore the normative basis for these performances and indicate that membership is still based on a contribution of work to the common good. This can best be conceptualised as a shifting continuity rather than a sharp break after 1989.     

Dual citizenship and theories of democracy

Dual/multiple citizenship has become a widespread phenomenon in many parts of the world. This acceptance or tolerance of overlapping memberships in political communities represents an important element in the ongoing readjustment of the relationship between citizens and political communities in democratic systems. This article has two goals and parts. First, it evaluates dual citizenship from the perspective of five normative theories of democracy. Liberal and republican as well as multicultural and deliberative understandings of democracy deliver a broad spectrum of arguments in favour of dual citizenship. Only communitarians fear that dual citizenship endangers national democracies. Nevertheless, empirical evidence and national policies largely contradict these fears. The second part of the article reverses the perspective and shows that most theories of democracy do not only legitimate and facilitate the acceptance of dual citizenship – the phenomenon of multiple citizenships induces innovation in democratic theory in turn. A second look at the relationship between dual citizenship and theories of democracy reveals that dual citizenship stimulates refinements, expansions and reconceptualisations of these theories for a transnationalising world.     

The detection of multiply charged dyes using matrix-assisted laser desorption/ionization mass spectrometry for the forensic examination of pen ink dyes directly from paper

Abstract:  Laser desorption mass spectrometry (LDMS) is emerging as a technique for questioned document examination. Its use is limited to detecting ink dyes that are neutral or singly charged. Several inks contain dyes that are multiply charged and LDMS cannot be employed for their identification. We have successfully detected >20 polyionic dyes that can be used in the manufacture of inks using matrix-assisted laser desorption/ionization (MALDI) MS, directly from paper, with the matrix, 2-(4-hydroxyphenylazo)benzoic acid (HABA), and the additive, diammonium hydrogen citrate (DAHC). For example, Acid Violet 49, a charged dye containing one positively-charged site and two negatively charged sulfonate groups, cannot be detected by LDMS, but forms intact, singly charged ions in the MALDI MS experiment. The method described is also useful for identifying multiply charged dye mixtures that are used in modern pen inks.     

The Future of Consumer Web Data: A European/US Perspective

The article considers the subject of clickstream data from aEuropean/US perspective, taking into account the Data ProtectionFramework (Data Protection Directive 95/46/EC; Directive onPrivacy and Electronic Communications 2002/58/EC) and the USlegal framework and in particular, the Wiretap Act U.S.C. 2701(2004) and related statutes. It examines the extent to whichclickstream data is considered "personal data" within the DataProtection Directive and the implications to consumers and businesses.     

The law and the sublime: Rethinking the self and its boundaries

Christine Battersby has argued that it is Kant (and not Descartes) who provides the paradigm model of what it is to be a self in modernity. The Kantian self is established in opposition to its other. The body is commonly envisaged as a container, with selfhood as something that is defended against the outside. In contrast, she proposes a feminist reworking of such a model of selfhood, applicable to both men and women, in which the self and other emerge over time through patterns of relationality. This paper introduces Battersby’s work by focusing upon her early analysis of Kantian aesthetics, in particular the sublime. The aim is to draw out some of the legal and political implications of her work, particularly with regard to the common law’s developing conception of privacy. This is carried out by distinguishing her ontological position from the psychology of Carol Gilligan and then by considering the overlapping concerns of Jennifer Nedelsky in the area of legal theory.
