Steven French and Decio Krause examine the metaphysical foundations of quantum physics. They draw together historical, logical, and philosophical perspectives on the fundamental nature of quantum particles and offer new insights on a range of important issues. Focusing on the concepts of identity and individuality, the authors explore two alternative metaphysical views; according to one, quantum particles are no different from books, tables, and people in this respect; according to the other, they most certainly are. Each view comes with (...) certain costs attached and after describing their origins in the history of quantum theory, the authors carefully consider whether these costs are worth bearing. Recent contributions to these discussions are analyzed in detail and the authors present their own original perspective on the issues. The final chapter suggests how this perspective can be taken forward in the context of quantum field theory. (shrink)

Most philosophers writing about personal identity in recent years claim that what it takes for us to persist through time is a matter of psychology. In this groundbreaking new book, Eric Olson argues that such approaches face daunting problems, and he defends in their place a radically non-psychological account of personal identity. He defines human beings as biological organisms, and claims that no psychological relation is either sufficient or necessary for an organism to persist. Olson rejects several famous (...) thought-experiments dealing with personal identity. He argues, instead, that one could survive the destruction of all of one's psychological contents and capabilities as long as the human organism remains alive--as long as its vital functions, such as breathing, circulation, and metabolism, continue.

In Consciousness and Persons: Unity and Identity, Michael Tye takes on the thorny issue of the unity of consciousness and answers these important questions: What exactly is the unity of consciousness? Can a single person have a divided consciousness? What is a single person? Tye argues that unity is a fundamental part of human consciousness -- something so basic to everyday experience that it is easy to overlook. For example, when we hear the sound of waves crashing on a (...) beach and at the same time see a red warning flag, there is an overall unity to our experience; the sound and the red shape are presented together in our consciousness. Similarly, when we undergo a succession of thoughts as we think something through, there is an experience of succession that unifies the thoughts into a conscious whole. But, Tye shows, consciousness is not always unified. Split-brain subjects, whose corpus callosum has been severed, are usually taken to have a divided or disunified consciousness. Their behavior in certain situations implies that they have lost the unity normal human subjects take for granted; it is sometimes even supposed that a split-brain subject is really two persons.Tye begins his account by proposing an account of the unity of experience at a single time; this account is extended over the succeeding chapters to cover bodily sensations at a single time and perceptual experience, bodily sensations, conscious thoughts, and felt moods at a single time. Tye follows these chapters with a discussion of the unity of experience through time. Turning to the split-brain phenomenon, he proposes an account of the mental life of split-brain subjects and argues that certain facts about these subjects offer support for his theory of unity. Finally, addressing the topic of the nature of persons and personal identity, Tye finds the two great historical accounts -- the ego theory and the bundle theory -- lacking and he makes an alternative proposal. He includes an appendix on the general representational approach to consciousness and its many varieties, because of the relevance of representationalism to the theory of unity being adanced.

In this book chapter, Moya argues that recognizing, indeed mobilizing, identities in the classroom is a necessary part of educating for a just and democratic society. Only a truly multi-perspectival, multicultural education can create the conditions needed to alter the negative identity contingencies that minority students commonly face, while creating opportunities for all students. By treating identities as epistemic resources and mobilizing them, we can draw out their knowledge-generating potential and allow them to contribute positively to the production and (...) transmission of knowledge.

Locke’s account of personal identity has been highly influential because of its emphasis on a psychological criterion. The same consciousness is required for being the same person. It is not so clear, however, exactly what Locke meant by ‘consciousness’ or by ‘having the same consciousness’. Interpretations vary: consciousness is seen as identical to memory, as identical to a first personal appropriation of mental states, and as identical to a first personal distinctive experience of the qualitative features of one’s own (...) thinking. There is wide agreement, however, that Locke’s theory of personal identity is meant to complement his moral and theological commitments to a system of divine punishment and reward in an afterlife. But these commitments seem to require also a metaphysical criterion, and Locke is insistent that it cannot be substance. The difficulty reconciling the psychological and metaphysical requirements of the theory has led, at worst, to charges of incoherence and, at best, to a slew of interpretations, none of which is widely accepted.

In this paper I argue that composition as identity entails unrestricted composition. I also briefly consider a new take on the special composition question.

In this essay I shall argue that the crucial assumptions of Kripke's argument, i.e. the collapse of the appearance/reality distinction in the case of phenomenal states and the idea of a qualitatively identical epistemic situation, imply an objective principle of identity for mental-state types. This principle, I shall argue, rather than being at odds with physicalism, is actually compatible with both the type-identity theory of the mind and Kripke's semantics and metaphysics. Finally, I shall sketch a version of (...) the type-identity theory. (shrink)

Genetic information is becoming increasingly used in modern life, extending beyond medicine to familial history, forensics and more. Following this expansion of use, the effect of genetic information on people’s identity and ultimately people’s quality of life is being explored in a host of different disciplines. While a multidisciplinary approach is commendable and necessary, there is the potential for the multidisciplinarity to produce conceptual misconnection. That is, while experts in one field may understand their use of a term like (...) ‘gene’, ‘identity’ or ‘information’ for experts in another field, the same term may link to a distinctly different concept. These conceptual misconnections not only increase inefficiency in complex organisational practices, but can also have important ethical, legal and social consequences. This paper comes at the problem of conceptual misconnection by clarifying different uses of the terms ‘gene’, ‘identity’ and ‘information’. I start by looking at three different conceptions of the gene; the Instrumental, the Nominal and the Postgenomic Molecular. Secondly, a taxonomy of four different concepts of identity is presented; Numeric, Character, Group and Essentialised, and their use is clarified. A general concept of Information is introduced, and finally three distinct kinds of information are described. I then introduce Concept Creep as an ethical problem that arises from conceptual misconnections. The primary goal of this paper is to reduce the potential for conceptual misconnection when discussing genetic identity and genetic information. This is complimented by three secondary goals—1) to clarify what a conceptual misconnection is, 2) to explain why clarity of use is particularly important to discussions of genes, identity and information and 3) to show how concept creep between different uses of genetic identity and genetic information can have important ethical outcomes.

Choosing to interact with others in an online forum provides an opportunity for exploring one’s own identity. With each new group joined, a person must make decisions about self-presentation and react to an audience. Such decisions continue as social interactions occur and relationships develop. This paper discusses how bloggers who have affiliated with each other to form a loosely knit community develop largely pseudonymous identities along with norms surrounding the development and performance of identity. The study is ethnographic (...) and longitudinal, examining a community of academics who blog and comment alongside each other in a diaristic manner. Focal areas include blog elements through which identity may be expressed, namely (1) Name and blog title; (2) Profiles; (3) Post content; (4) Voice; (5) Affiliations; and (6) Visual design; the effect of pseudonyms on blog authors and readers; and how issues of privacy and trust are manifest in the community.

Driven by privacy-related fears, users of Online Social Networks may start to reduce their network activities. This trend can have a negative impact on network sustainability and its business value. Nevertheless, very little is understood about the privacy-related concerns of users and the impact of those concerns on identity performance. To close this gap, we take a systematic view of user privacy concerns on such platforms. Based on insights from focus groups and an empirical study with 210 subjects, we (...) find that (i) Organizational Threats and (ii) Social Threats stemming from the user environment constitute two underlying dimensions of the construct Privacy Concerns in Online Social Networks . Using a Structural Equation Model, we examine the impact of the identified dimensions of concern on the Amount, Honesty, and Conscious Control of individual self-disclosure on these sites. We find that users tend to reduce the Amount of information disclosed as a response to their concerns regarding Organizational Threats. Additionally, users become more conscious about the information they reveal as a result of Social Threats. Network providers may want to develop specific mechanisms to alleviate identified user concerns and thereby ensure network sustainability. (shrink)

This paper explores the intersections between national identity and the production of medical/population genomics in Mexico. The ongoing efforts to construct a Haplotype Map of Mexican genetic diversity offers a unique opportunity to illustrate and analyze the exchange between the historic-political narratives of nationalism, and the material culture of genomic science. Haplotypes are central actants in the search for medically significant SNP’s, as well as powerful entities involved in the delimitation of ancestry, temporality and variability. By following the circulation (...) of Haplotypes, light is shed on the alignments and discordances between socio-historical and bio-molecular mappings. The analysis is centred on the comparison between the genomic construction of time and ethnicity in the laboratory, and on the public mobilisation of a “Mexican Genome” and its wider political implications. Even though both: the scientific practice and the public discourse on medical/population genomics are traversed by notions of “admixture”, there are important distinctions to be made. In the public realm, the nationalist post-revolutionary ideas of Jose Vasconcelos, as expressed in his Cosmic Race, still hold sway in the social imaginary. In contrast, admixture is treated as a complex, relative and probabilistic notion in laboratory practices. I argue that the relation between medical/population genomics and national identity is better understood as a process of re-articulation, rather than coproduction of social and natural orders. The evolving process of re-articulation conceals the novelty of medical/population genomics, aligning scientific facts in order to fit the temporal and ethnic grids of “Mestizaje”. But it is precisely the social and political work, that matches the emerging field of population genomics to the pre-existing projects of national identity, what is most revealing in order to understand the multiple and even subtle ways in which population genomics challenges the historical and identitarian frames of a “Mestizo” nation.

Issues of identity and reduction have monopolized much of the philosopher of mind’s time over the past several decades. Interestingly, while investigations of these topics have proceeded at a steady rate, the motivations for doing so have shifted. When the early identity theorists, e.g. U. T. Place ( 1956 ), Herbert Feigl ( 1958 ), and J. J. C. Smart ( 1959 , 1961 ), fi rst gave voice to the idea that mental events might be identical to (...) brain processes, they had as their intended foil the view that minds are immaterial substances. But very few philosophers of mind today take this proposal seriously. Why, then, the continued interest in identity and reduction? Th e concern, as philosophers like Hilary Putnam and Jerry Fodor have expressed it, is that a victory for identity or reduction is a defeat for psychology. For if minds are physical, or if mental events are physical events, then psychologists might as well disassemble their laboratories, making room for the neuroscientists and molecular biologists who are in a better position to explain those phenomena once misdescribed as “psychological.” Th e worry nowadays is not that locating thought in immaterial souls will make psychology intractable, but that locating thoughts in material brains will make it otiose.

The issue of identity cards is hotly debated in many countries, but it often seems to be an oddly backward-looking debate that presumes outdated “Orwellian” architectures. In the modern world, surely we should be debating the requirements for national identity management schemes, in which identity cards may or may not be a useful implementation, before we move on to architecture. If so, then, what should a U.K. national identity management scheme for the 21st century look like? (...) Can we assemble a set of requirements understandable to politicians, professionals and the public? We’ve certainly had some difficulty to date. One reason might be that we lack a compelling, narrative vision. As a result, we’re constructing a legacy system that will subvert the rational goals of worthwhile scheme. We’re not aiming high enough. The technology, I will argue, can deliver far more than the politicians, professionals and public imagine: In particular, it can deliver the apparently paradoxical result of more security and more privacy by exploiting smart cards, biometrics and cryptography. In this paper, I will set out a high-level vision of what a forward-looking national identity management and identity “card” scheme should look like: Dr. Who’s psychic paper. Not only is this a simple, clear vision that is familiar to the expert and layperson alike, but it’s a very useful artistic representation of the capabilities of the technology. I will further suggest that a utility implementation of identity infrastructure can deliver the on this vision in a practical way, and that all of the technology needed to create an ID scheme for the future already exists.

Those who work with topics related to Modern Greek identity usually start discussing these issues by quoting the famous Georgios Gemistos Pletho (c.1360-1454): we, over whom you rule and hold sway, are Hellenes by genos (γένος), as is witnessed by our language and ancestral education. Although Woodhouse thought of Pletho as the last of the Hellenes, others prefer to denounce him the last of the Byzantines and the first and foremost Modern Greek. During the 14th and 15th centuries, a (...) number of influential intellectuals in the Eastern Roman Empire preferred the term Hellene (Ἓλλην) to identify themselves, instead of the formal Roman (Ρωμαῖος) and the common Greek (Γραικός). According to the prevalent view of modern scholarship, the shift should not be interpreted only as a statement of proto-national identity, but also as the outcome of growing archaism. As Vryonis pointed out, the historian Critoboulos used to call the Balkan nations with their archaic names: Byzantines became “Hellenes,” Albanians became “Illyrians,” etc. Chalkokondyles followed in the same path. Furthermore, in order to lament the decline of their Empire, byzantine intellectuals tended to compare their sad present to the glory of ancient Greece. Besides archaism, proto-nationalism and Hellenism, I suggest that a careful reading of the sources would lead us to reappraise the ways 15th century intellectuals perceived identity. Whilst I do not accept Vakalopoulos’ views on diachronic Hellenic identity, I support that, in the 15th century, Byzantine scholars attempted to create an identity based on cultural and historical continuity and otherness. Moreover, Laiou’s definition of Greek identity as a resultant of language, history, tradition and interests does not cover the case of 15th century Byzantine philosophers, since the latter strived to enrich and enlarge Greek identity with additional elements. It is worth noting that those philosophers who fled to Italy deliberately chose to describe themselves as Greeks (Greci/Γραικοί) or Hellenes (Ἓλληνες) and not as Romans (Ρωμιοί/Ρωμαῖοι), according to the Byzantine official terminology. During the 15th century a major shift occurred in the Byzantine intelligentsia and its prominent members revisited matters of identity. In this paper, I attempt to scrutinize the ways Byzantine philosophers of the 15th century, who lived in the territories of the Byzantine Empire and in Italy, perceived identity and otherness. In my research, I include not only Greek, but also Latin sources, since their works is written in both languages. (shrink)

In this article, I argue that lawmakers must abandon their previous reluctance to engage with questions of personal identity. While frequently seen as an esoteric subject, of limited interest outside of academic philosophy departments, I attempt to show that, in fact, assumptions about PI—and its durability in the face of certain psychological or genetic changes—underpin many current legal rules. This is most perhaps obviously exemplified with regard to reproductive technologies. Yet the Parfitian challenge to identify a victim of ‘bad’ (...) reproductive choices has been largely overlooked in framing legislative responses to such technologies. Furthermore, I argue, it is not only with regard to emerging technologies that questionable assumptions about PI play a role; legal responses to questions about the attribution of criminal responsibility, and about the treatment of demented or brain-injured people, necessitate a frank engagement with such questions. It may be, however, that a multi-faceted approach to PI, which takes account of genetic, psychological and social factors—will prove a better fit for the myriad needs of the legal system than any sort of ‘unified theory of identity’.

As research into identity in the information society gets into its stride, with contributions from many scholarly disciplines such as technology, social sciences, the humanities and the law, a moment of intellectual stocktaking seems appropriate. This article seeks to provide a roadmap of research currently undertaken in the field of identity and identity management showing how the area is developing and how disparate contributions relate to each other. Five different perspectives are proposed through which work in the (...) identity field can be seen: tensions, themes, application areas, research focus and disciplinary approaches and taken together they provide a comprehensive overview of the intellectual territory currently being tilled by academia on this subject. This attempt at a coherent overview is offered in the spirit of debate and discussion, and the authors invite criticism, development and improvement. Another purpose of this paper is to provide an introduction to the range and type of research that the new journal Identity in the Information Society will publish, giving researchers working in the field a clearer idea of the scope of multidisciplinary study that is envisaged.

This paper discusses the “blended identity” of online rock fans to show that the standard dichotomy between anonymous and real life personas is an inadequate description of self-presentation in online communities. Using data from an ethnographic, exploratory study of an online community and comparison groups including interviews, an online questionnaire, fan discussion boards, and participant/observation, the research analyzes fan identity online and then offline. Rolling Stones fans often adopt names that illustrate their allegiance to the band, along with (...) avatars. Issues of gender and the technological change of software platform also affect types of online self-presentations and their construction. Fans engage in “role embracement”, merging their individual selves with the role of Stones fans, demonstrated by reactions of friends and family. Connections between offline and online settings occur, with band affiliation of fans expressed through choice of apparel offline, and usernames from online filtering into the offline interactions among fans.

This paper presents a framework for the design of human-centric identity management systems. Whilst many identity systems over the past few years have been labelled as human-centred, we argue that the term has been appropriated by technologists to claim moral superiority of their products, and by system owners who confuse administrative convenience with benefits for users. The framework for human-centred identity presented here identifies a set of design properties that can impact the lived experience of the individuals (...) whose identity is being managed. These properties were identified through an analysis of public response to 15 historic national identity systems. They capture the practical design aspects of an identity system, from structural aspects that affect the flow of information - Control Points, Subject Engagement, Identity Exposure, Population Coverage—to the metrical aspects that considers how information is used and perceived—Expert Interpretation, Population Comprehension, Information Accuracy, Information Stability, Subject Coupling, Information Polymorphism. Any identity system can be described in terms of these fundamental properties, which affect individuals’ lived experience, and therefore help to determine the acceptance or rejection of such systems. We first apply each individual property within the context of two national identity systems—the UK DNA Database and the Austrian Citizen Card, and then also demonstrate the applicability of the framework within the contexts of two non-government identity platforms—Facebook and Phorm. Practitioners and researchers would make use of this framework by analysing an identity system in terms of the various properties, and the interactions between these properties within the context of use, thus allowing for the development of the potential impacts that the system has on the lived experience.

The individual management of online identity, as part of a wider politics of personal information, privacy, and dataveillance, is an area where public policy is developing and where the public sector attempts to intervene. This paper attempts to understand the strategies and methods through which the UK government and public sector is engaging in online identity management. The analysis is framed by the analytics of government and governmentality. This approach draws attention to the wide assemblage of public and (...) private actors with shared regimes of practice and fields of visibility, as well as to the extent to which individual actors are made responsible for their own identity management. The paper also uses communication and discursive research to examine the potential failings of engagement efforts. Communication theory suggested that the assumption of individual responsibility, alongside linguistic distortions created by this way of understanding the problematic of identity management, complicate and fundamentally limit engagement activity.

The Web 2.0, with online social technologies such as social networking services, blogs, wikis, or microbloging, has brought the vision of the Internet as a social landscape in which people are engaged in a multitude of social activities. This editorial of the special issue ‘Social Web and Identity’ discusses the importance of identity in the context of the Social Web, introducing the different papers of this special issue and the different aspects associated to these online identities. The topics (...) covered in this issue include how people define their identity in blogs and what is the articulation between online and offline identities in these systems. It also presents an article studying the privacy issues in online social networks and more specifically how these risks are perceived and how people can control their identity in this context. The next article compares privacy in two different categories of social systems (social network and collaborative workspace). Finally, another article discusses to what extent the current legislation, such the data protection regulations directive 95/46/EC, is providing the right instrument for dealing with privacy issues.

This article claims that an ‘enclosure of the commons’ is underway, which reaches far beyond intellectual property, to a point where, through profiling, ‘identity’ has itself become enclosed property that can be owned by another.

A real but typical case of identity fraud is used to open up the complex web of identification systems in Brazil. It is argued that identification has two poles related to the nature of citizenship—repression and inclusion—and that reactions from citizens to new identification schemes can be attributed to how they view the purpose of the cards in these terms. In Brazil, a sense of inclusion and citizenship based on a fear of anonymity and exclusion predominates leading to widespread (...) support amongst even critics of state activities. However, this may be undermined by the lack of state preparation for an information society, particularly the absence of meaningful data protection laws. (shrink)

The article argues for a shift of perspective in identity management research and development. Accessibility and usability issues affect identity management to such an extent that they demand a reframing and reformulation of basic designs and requirements of modern identity management systems. The rationale for the traditional design of identity management systems and mechanisms has been security concerns as defined in the field of security engineering. By default the highest security level has been recommended and implemented, (...) often without taking end-user needs and accessibility issues into serious consideration. The article provides a conceptual framework for inclusive IDM, a brief overview of the regulatory status of inclusive IDM and a taxonomy of inclusive identity management methods. Several widespread IDM approaches, methods and techniques are analyzed and discussed from the perspective of inclusive design. Several important challenges are identified and some ideas for solutions addressing the challenges are proposed and discussed. (shrink)

The never ending growth of digital information and the availability of low-cost storage facilities and networks capacity is leading users towards moving their data to remote storage resources. Since users’ data often holds identity-related information, several privacy issues arise when data can be stored in untrusted domains. In addition digital identity management is becoming extremely complicated due to the identity replicas proliferation necessary to get authentication in different domains. GMail and Amazon Web Services, for instance, are two (...) examples of online services adopted by million of users throughout the world which hold huge amounts of sensitive users data. State-of-the-art encryption tools for large-scale distributed infrastructures allow users to encrypt content locally before storing it on a remote untrusted repository. This approach can experience performance drawbacks, when very large data-sets must be encrypted/decrypted on a single machine. The proposed approach extends the existing solutions by providing two additional features: (1) the encryption can also be delegated to a pool of remote trusted computing resources, and (2) the definition of the encryption context which drives the tool to select the best strategy to process the data. The performance benchmarks are based on the results of tests carried out both on a local workstation and on the Grid INFN Laboratory for Dissemination Activities (GILDA) testbed. (shrink)

The present paper summarizes the development of the national electronic Identity Management System (eIDMS) in Estonia according to a conceptual framework developed in an European comparative research project outlined in the first chapter of this special issue. Its main function is to amend the picture of the European eIDMS landscape by presenting a case with high involvement of the private sector and thereby checking the generalizations from the comparisons of Austria, Belgium, Germany and Spain, presented by Kubicek and Noack (...) in the previous chapter of this special issue. Starting with a short introduction into the historical background of identity documents in Estonia the national population register, the passport as well as the bank ID are described as the main pillars of the Estonian eIDMS, on which the national ID card builds on, which has been introduced in 2002. The technical features of the eID and the ID card are described in Section two as well as the areas of application and the processes for production and distribution. Section three presents the actors constellation, Section four the time line of the development process, starting from 1997. Section five deals with the diffusion and promotion of the ID card and the eID authentication function. After a very low and slow take up during the first 5 years due to a cooperation agreement between major banks, telecom operators and the government usage has increased. But still the authentication by Internet banks, which provides authentication services to third parties, including government, is the biggest competitor for the eID function on the national eID card. Only recently the major banks have announced to slowly fade out the password cards and PIN calculators as alternative modes of bank authentication. (shrink)

This chapter describes the introduction and diffusion of the Finnish Electronic Identity Card (FINEID card). FINEID establishes an electronic identity (eID), based on the civil registry and placed on an identity chip card issued by Finnish government to Finnish citizens and permanent residents from age 18 and older. It is a non-mandatory electronic identity card introduced in 1999 in order to replace the older citizen ID card. It serves as a travel document and is intended to (...) facilitate access to eGovernment services as well as offering a possibility to sign electronically. Therefore the chip contains two certificates: one for authentication purposes, and one for qualified signatures. The eID function had to compete with the already existing PIN/TAN based TUPAS standard for online authentication for eBanking, eCommerce and eGovernment applications, and has lost this battle by reaching less than one percent of all online authentications. The history, actor constellation, time line and barriers will be described and a few communalities and differences to other countries under study in this special issue will be highlighted. (shrink)

Identity governance is an emerging concept for fine-grained conditional disclosure of identity information and enforcement of corresponding data handling policies. Although numerous technologies underlying identity management have been developed, people still have difficulty obtaining a clear picture of how their identity information is maintained, used, and propagated. An identity management framework is described for tracking the history of how a person’s identity information is handled after it is transferred across domains of control and for (...) enforcing meta-policies related to managing identity information distributed over the Internet. With this framework, organizations that manage identity information can improve accountability for their data practices and thereby increase their trustworthiness. The framework also enables users to control and optimize the propagation of their identity information in a user-centric manner. (shrink)

Over the past few years, the Virtual Organization (VO) paradigm has been emerging as an ideal solution to support collaboration among globally distributed entities (individuals and/or organizations). However, due to rapid technological and societal changes, there has also been an astonishing growth in technologies and services for mobile users. This has opened up new collaborative scenarios where the same participant can access the VO from different locations and mobility becomes a key issue for users and services. The nomadicity and mobility (...) introduces additional challenges for managing collaboration in VO environments. This paper focuses on the Identity Management challenge in a Mobile Dynamic VO environment, which is a VO that takes into account nomadicity and seamless mobility aspects as elaborated within the EU funded project Akogrimo (Access to Knowledge through the Grid in a mobile world). The resulting work is the design of the Akogrimo Identity Management system supporting the authentication and authorization process across the different administrative domains of the Mobile Dynamic VO. This design follows the service oriented approach and integrates the different perspectives: that of the network, that of the user and that of the service provider. Such an integration requires facing challenges; both from the architectural and technological viewpoints because different ‘worlds’ (i.e. network and service level) leverage different (and sometimes conflicting) approaches when addressing Identity Management.

Today, Service-Oriented Architecture (SOA) and Grid and Cloud computing comprise the key technologies in distributed systems. In systems following the SOA approach, functionalities are delivered and consumed as services. Given the variety of resources (i.e. data, computing capabilities, applications, etc) as well as the variation of user-requested Quality of Service (e.g., high performance, fast access, low cost, high media resolution, etc), there is a need for advanced user management, trust establishment and service management mechanisms which adjust, monitor and evaluate service (...) provision according to the users’ requirements and rights. Within this context, security and privacy requirements have become of great importance, as well the need for flexible and efficient identity management. This editorial of the special issue Identity Management in Grid and SOA discusses the importance of identity management within SOA and Grid environments. A number of techniques and existing systems addressing these issues are presented and evaluated. Identity management is considered in various contexts and at different levels, including service composition level, system level and inter-system communication level. (shrink)

Providing Single Sign-On (SSO) between service providers and enabling service providers to share user personal attributes are critical for both users to benefit from a seamless access to their services, and service providers to realize new business opportunities. Today, however, the users have several independent, partial identities spread over different service providers. Providing SSO and attribute sharing requires that links (federations) are established between (partial) identities. In SAML 2.0 (Maler et al. 2003), the links between identities are stored and managed (...) at the network side by the identity providers (network-side identity federation). This model prevents the service providers from mass-correlating the partial identities they have, but the users must fully trust the identity providers. In this paper, we propose a complementary approach where the users have a full control of the links between their partial identities. It is a client-side identity federation approach, which relies on the introduction of a new cryptographic tool, called invariable partially blind signature scheme, that may be of independent interest.

Nine years before the fall of Constantinople, in 1444, cardinal Bessarion in his third and last letter addressed to Constantine Palaeologus, Despot of Mystra, expressed his deep concern about the economic, political, cultural, social and moral crisis, maintaining that the multidimensional crisis would inevitably lead to Byzantium’s decline. Bessarion stresses that the aristocracy’s biased policy, the burdensome taxation, the low level of business activity, the complete lack of technological advancements and the deficient education system not only shaped the Peloponnesian state (...) but also transformed the once brave, conscientious and studious Greeks into a cowardly, indolent and ignorant people. Realizing that the constitution of Greek society and the behavior of its citizens are impediments to modernization and to cultural progress, Bessarion proposes a series of reforms based on a revival of Ancient Greek culture and on technological advances of West that would lead to a well-governed, self-sufficient and independent Greek state. On 23 April 2010, 566 years after Bessarion’s letter, the Greek government requested financial assistance from the European Support Mechanism in order to avert the probability of default in Greece. The fiscal deficit, the swelling sovereign debt and the global financial recession shape Greece in crisis. The aim of this paper is to give an interpretative presentation of Bessarion’s letter with reference to modern Greece; to analyze the causes of the Byzantine Empire’s decline and the recommended reforms in comparison to the causes of the financial crisis in Greece and the implementation of austerity measures. I will prove that nowadays modern Greeks face the same problems with the Greeks of Peloponnese such as political corruption, administrative incompetence, excessive taxation, economic impoverishment, class inequality, unemployment, reduced business activity and inability to exploit natural resources. In this sense, I will show that the identity crisis of modern Hellenism was first cultivated and formed gradually from the Renaissance to modern Greece. (shrink)

Memory of past episodes provides a sense of personal identity — the sense that I am the same person as someone in the past. We present a neurological case study of a patient who has accurate memories of scenes from his past, but for whom the memories lack the sense of mineness. On the basis of this case study, we propose that the sense of identity derives from two components, one delivering the content of the memory and the (...) other generating the sense of mineness. We argue that this new model of the sense of identity has implications for debates about quasi-memory. In addition, articulating the components of the sense of identity promises to bear on the extent to which this sense of identity provides evidence of personal identity. (shrink)

This paper offers a critical assessment of the current state of the debate about the identity and individuality of material objects. Its main aim, in particular, is to show that, in a sense to be carefully specified, the opposition between the Leibnizian ‘reductionist’ tradition, based on discernibility, and the sort of ‘primitivism’ that denies that facts of identity and individuality must be analysable has become outdated. In particular, it is argued that—contrary to a widespread consensus—‘naturalised’ metaphysics supports both (...) the acceptability of non-qualitatively grounded (both ‘contextual’ and intrinsic) identity and a pluralistic approach to individuality and individuation. A case study is offered that focuses on non-relativistic quantum mechanics, in the context of which primitivism about identity and individuality, rather than being regarded as unscientific, is on the contrary suggested to be preferable to the complicated forms of reductionism that have recently been proposed. More generally, by assuming a plausible form of anti-reductionism about scientific theories and domains, it is claimed that science can be regarded as compatible with, or even as suggesting, the existence of a series of equally plausible grades of individuality. The kind of individuality that prevails in a certain context and at a given level can be ascertained only on the basis of the specific scientific theory at hand. (shrink)

In discussions about whether the Principle of the Identity of Indiscernibles is compatible with structuralist ontologies of mathematics, it is usually assumed that individual objects are subject to criteria of identity which somehow account for the identity of the individuals. Much of this debate concerns structures that admit of non-trivial automorphisms. We consider cases from graph theory that violate even weak formulations of PII. We argue that (i) the identity or difference of places in a structure (...) is not to be accounted for by anything other than the structure itself and that (ii) mathematical practice provides evidence for this view. We want to thank Leon Horsten, Jeff Ketland, Øystein Linnebo, John Mayberry, Richard Pettigrew, and Philip Welch for valuable comments on drafts of this paper. We are especially grateful to Fraser MacBride for correcting our interpretation of two of his papers and for other helpful comments. CiteULike Connotea Del.icio.us What's this? (shrink)

This paper employs a case study from the history of neuroscience—brain reward function—to scrutinize the inductive argument for the so-called ‘Heuristic Identity Theory’ (HIT). The case fails to support HIT, illustrating why other case studies previously thought to provide empirical support for HIT also fold under scrutiny. After distinguishing two different ways of understanding the types of identity claims presupposed by HIT and considering other conceptual problems, we conclude that HIT is not an alternative to the traditional (...) class='Hi'>identity theory so much as a relabeling of previously discussed strategies for mechanistic discovery.

Some authors have claimed that ante rem structuralism has problems with structures that have indiscernible places. In response, I argue that there is no requirement that mathematical objects be individuated in a non-trivial way. Metaphysical principles and intuitions to the contrary do not stand up to ordinary mathematical practice, which presupposes an identity relation that, in a sense, cannot be defined. In complex analysis, the two square roots of –1 are indiscernible: anything true of one of them is true (...) of the other. I suggest that ‘i’ functions like a parameter in natural deduction systems. I gave an early version of this paper at a workshop on structuralism in mathematics and science, held in the Autumn of 2006, at Bristol University. Thanks to the organizers, particularly Hannes Leitgeb, James Ladyman, and Øystein Linnebo, to my commentator Richard Pettigrew, and to the audience there. The paper also benefited considerably from a preliminary session at the Arché Research Centre at the University of St Andrews. I am indebted to my colleagues Craige Roberts, for help with the linguistics literature, and Ben Caplan and Gabriel Uzquiano, for help with the metaphysics. Thanks also to Hannes Leitgeb and Jeffrey Ketland for reading an earlier version of the manuscript and making helpful suggestions. I also benefited from conversations with Richard Heck, John Mayberry, Kevin Scharp, and Jason Stanley. CiteULike Connotea Del.icio.us What's this? (shrink)

The ethics literature has identified moral motivation as a factor in ethical decision-making. Furthermore, moral identity has been identified as a source of moral motivation. In the current study, we examine religiosity as an antecedent to moral identity and examine the mediating role of self-control in this relationship. We find that intrinsic and extrinsic dimensions of religiosity have different direct and indirect effects on the internalization and symbolization dimensions of moral identity. Specifically, intrinsic religiosity plays a role (...) in counterbalancing the negative impact of extrinsic religiosity on the internalization of moral identity. Further, intrinsic religiosity also counterbalances the negative and indirect impact of extrinsic religiosity on symbolization of moral identity via self-control. Lastly, self-control does not play a mediating role in the impact of religiosity on the internalization dimension of moral identity. We conclude that this study presents important findings that advance our understanding of the antecedents of moral identity, and that these results may have implications for the understanding of ethical decision-making.

This paper is about intentional identity, the phenomenon of intentional attitudes having a common focus. I present an argument against an approach to explaining intentional identity, defended by Nathan Salmon, Terence Parsons and others, that involves positing exotic objects. For example, those who adopt this sort of view say that when two astronomers had beliefs about Vulcan, their attitudes had a common focus because there is an exotic object that both of their beliefs were about. I argue that (...) countenancing these exotic objects does not help us explain intentional identity. (shrink)

According to realist structuralism, mathematical objects are places in abstract structures. We argue that in spite of its many attractions, realist structuralism must be rejected. For, first, mathematical structures typically contain intra-structurally indiscernible places. Second, any account of place-identity available to the realist structuralist entails that intra-structurally indiscernible places are identical. Since for her mathematical singular terms denote places in structures, she would have to say, for example, that 1 = − 1 in the group (Z, +). We call (...) this the identity problem and conclude that nominalism is presently the safest route for the structuralist. (shrink)

In this book, Eli Hirsch focuses on identity through time, first with respect to ordinary bodies, then underlying matter, and eventually persons.

A theory of gender ought to be compatible with trans-inclusive definitions of gender identity terms, such as ‘woman’ and ‘man’. Appealing to this principle of trans-inclusion, Katharine Jenkins argues that we ought to endorse a dual social position and identity theory of gender. Here, I argue that Jenkins’ dual theory of gender fails to be trans-inclusive for the following reasons: (i) it cannot generate a definition of ‘woman’ that extends to include all trans women, and (ii) it understands (...) transgender gender identity through a cisgender frame.

Kimberlé Williams Crenshaw ends her landmark essay “Mapping the Margins: Intersectionality, Identity Politics, and Violence against Women of Color” with a normative claim about coalitions. She suggests that we should reconceptualize identity groups as “in fact coalitions,” or at least as “potential coalitions waiting to be formed.” In this essay, I explore this largely overlooked claim by combining philosophical analysis with archival research I conducted at the Gay, Lesbian, Bisexual and Transgender Historical Society Archive in San Francisco about (...) Somos Hermanas, the solidarity project of the Alliance Against Women’s Oppression, based in the San Francisco Women’s Building (1984–90). I extend my analysis into the present by drawing on the oral history and published works of Carmen Vázquez, a key organizer in both Somos Hermanas and the Women’s Building. I argue that conceptualizing identities as in fact coalitions—as complex, internally heterogeneous unities constituted by their internal differences and dissonances and by internal as well as external relations of power—enables us to organize effective political coalitions that cross existing identity categories and to pursue a liberatory politics of interconnection.

Many of us agree that we ought not to wrong future people, but there remains disagreement about which of our actions can wrong them. Can we wrong individuals whose lives are worth living by taking actions that result in their very existence? The problem of justifying an answer to this question has come to be known as the non-identity problem.[1] While the literature contains an array of strategies for solving the problem,[2] in this paper I will take what I (...) call the harm-based approach, and I will defend an account of harming—which I call the existence account of harming—that can vindicate this approach. -/- Roughly put, the harm-based approach holds that, by acting in ways that result in the existence of individuals whose lives are worth living, we can harm and thereby wrong those individuals. An initially plausible way to try to justify this approach is to endorse the non-comparative account of harming, which holds that an event harms an individual just in case it causes her to be in a bad state, such that the state’s badness does not derive from a comparison between that state and some alternative state that the individual would or could have been in. However, many philosophers argue that the non-comparative account of harming is inadequate,[3] and one might be tempted to infer from this that any harm-based approach to the non-identity problem will fail. My proposal, which I call the existence account of harming, will show that this inference is faulty: we can vindicate the harm-based approach without relying on the non-comparative account of harming.

This review aims to identify (1) sources of knowledge and (2) important themes of the ethical debate related to surgical alteration of facial features in East Asians. This article integrates narrative and systematic review methods. In March 2014, we searched databases including PubMed, Philosopher’s Index, Web of Science, Sociological Abstracts, and Communication Abstracts using key terms “cosmetic surgery,” “ethnic*,” “ethics,” “Asia*,” and “Western*.” The study included all types of papers written in English that discuss the debate on rhinoplasty and blepharoplasty (...) in East Asians. No limit was put on date of publication. Combining both narrative and systematic review methods, a total of 31 articles were critically appraised on their contribution to ethical reflection founded on the debates regarding the surgical alteration of Asian features. Sources of knowledge were drawn from four main disciplines, including the humanities, medicine or surgery, communications, and economics. Focusing on cosmetic surgery perceived as a westernising practice, the key debate themes included authenticity of identity, interpersonal relationships and socio-economic utility in the context of Asian culture. The study shows how cosmetic surgery of ethnic features plays an important role in understanding female identity in the Asian context. Based on the debate themes authenticity of identity, interpersonal relationships, and socio-economic utility, this article argues that identity should be understood as less individualistic and more as relational and transformational in the Asian context. In addition, this article also proposes to consider cosmetic surgery of Asian features as an interplay of cultural imperialism and cultural nationalism, which can both be a source of social pressure to modify one’s appearance.

Occasions of Identity is an exploration of timeless philosophical issues about persistence, change, time, and sameness. Andre Gallois offers a critical survey of various rival views about the nature of identity and change, and puts forward his own original theory. He supports the idea of occasional identities, arguing that it is coherent and helpful to suppose that things can be identical at one time but distinct at another. Gallois defends this view, demonstrating how it can solve puzzles about (...) persistence dating back to the Ancient Greeks, and investigates the metaphysical consequences of rejecting the necessity and eternity of identities.

Dominant views of personal identity in philosophy take some kind of psychological continuity or connectedness over time to be criterial for the identity of a person over time. Such views assign psychological states, particularly those necessary for narrative memory of some kind, special importance in thinking about the nature of persons. The extended mind thesis, which has generated much recent discussion in the philosophy of mind and cognitive science, holds that a person’s psychological states can physically extend beyond (...) that person’s body. Since “person” is a term of both metaphysical and moral significance, and discussions of both extended minds and personal identity have often focused on memory, this article explores the relevance of extended cognition for the identity of persons with special attention to neuroethics and memory.

In attempting to understand personal identity, it is common practice to imagine a person existing at some time t and a person existing at a time t* , and then to ask, What does it take for person x at t to be the same person as person y at t*?The Psychological Continuity Approach answers: there is a relation, R, of psychological continuity such that person x at t is the same person as person y at t* if and (...) only if x at t bears R to y at t*.But maybe the question above is not the right one to ask when trying to understand personal identity. Olson calls this the narrow question of personal identity, which he distinguishes from the broad question: What does it take for person x at t to be the same individual as y at t*? (shrink)

Questions about the relation between identity and discernibility are important both in philosophy and in model theory. We show how a philosophical question about identity and dis- cernibility can be ‘factorized’ into a philosophical question about the adequacy of a formal language to the description of the world, and a mathematical question about discernibility in this language. We provide formal definitions of various notions of discernibility and offer a complete classification of their logical relations. Some new and surprising (...) facts are proved; for instance, that weak dis- cernibility corresponds to discernibility in a language with constants for every object, and that weak discernibility is the most discerning nontrivial discernibility relation.

In this chapter I discuss Charles Taylor's and Paul Ricoeur's theories of narrative identity and narratives as a central form of self-interpretation. Both Taylor and Ricoeur think that self-identity is a matter of culturally and socially mediated self-definitions, which are practically relevant for one's orientation in life. First, I will go through various characterisations that Ricoeur gives of his theory, and try to show to what extent they also apply to Taylor's theory. Then, I will analyse more closely (...) Charles Taylor's, and in section three, Paul Ricoeur's views on narrative identity. (shrink)
